 Conveyance device for conveyed goods, method for unloading conveyed goods from transport container using the same, and method for loading conveyed goods into transport container

 Technical field

 The present invention relates to a device for transporting a transported object, a method for unloading a transported item from a transport container using the same, and a method for loading a transported item into the transport container. Transport equipment that can safely transport goods with an inexpensive and simple structure that can transport the goods of the same type, a method of unloading the goods from the transport container using the same, and the goods that are transported to the transport container Related to the carrying out method.

 Background art

 [0002] Conventionally, as a method of transporting cargo by truck, railcar, ship, or the like, container transport using a container is known. There are many types of containers that can be selected depending on the application, etc. However, dry containers are the most owned and inexpensive and easy to secure. However, since the dry container has an opening only on one end side, it is necessary to load heavy cargo, long cargo, bulky cargo, etc. into the dry container (called banjung) or unload it. (Called Devang Jung) was extremely difficult.

 In special containers such as flat containers and open-top containers, cargo hung by a crane or the like from the open ceiling can be loaded into or unloaded from containers, but these special containers are dry containers. It is more expensive than containers and has a smaller distribution volume!

 [0003] In order to solve the above problem, the present applicant has proposed a transfer device and a transfer method capable of transferring various conveyed items to a container (particularly, a dry container) via a pallet. (For example, see Patent Documents 13).

[0004] For example, Patent Documents 1 and 2 disclose a stage side for supporting a transported product pallet movably up and down and horizontally movable on the floor of a stage adjacent to the opening side of a container. Elevating sliding means is provided, and container-side elevating sliding means is provided on the floor surface of the container so as to freely and horizontally move the loading pallet. Which can transfer a pallet loaded with goods between a stage-side elevating sliding means and a container-side elevating sliding means. As a result, heavy cargo, long cargo, bulky cargo, etc. can be efficiently handled at containers at distribution centers handling large quantities and various types of cargo, such as C'F'S (container 'freight' stations). Can be transported. As a result, container transportation of heavy cargo, long cargo and bulky cargo can be realized.

 [0005] However, in Patent Document 1 and Patent Document 2, it is necessary to provide two transport means, a stage-side elevating / sliding means and a container-side elevating / sliding means, which is relatively expensive. In addition, special large-sized transfer means (for example, a push-pull mechanism) must be provided to transport the loaded pallets to the correct transport position on the container or stage, and these must be properly driven and controlled. there were.

 Here, in places where large volumes of cargo do not need to be handled frequently (for example, on the receiving side of cargo overseas), even if the transport efficiency is slightly reduced, it is relatively inexpensive, has a simple structure, and is safe. There has been a demand for a transport device capable of transporting various transport objects.

 [0006] Further, for example, in Patent Document 3 described above, a conveyed product is loaded between a container and a stage adjacent to the opening side of the container by an air-floating carrier operated by an operator. A pallet is disclosed in which a pallet is conveyed while also raising the floor surface force. As a result, a plurality of cargoes (especially, coiled steel, etc.) having a size of about 1Z4 of the entire length of the container can be efficiently transported to the container.

 However, in Patent Document 3 described above, heavy cargo, long cargo, bulky cargo, and the like having the size of the entire length of the container cannot be transported.

 [0007] Conventionally, there has been a demand for transporting heavy objects such as press dies by rail in containers. However, long-term vibration of railway vehicles and shocks at the time of connection could cause the container floor to fall off, causing damage to luggage, and rail transport of heavy goods had not been realized. In particular, in the above-mentioned press die, usually, a force that simultaneously transports a measuring device for measuring the molding accuracy of the die (also referred to as a checking Z fixture). Because of its susceptibility, it was not suitable for rail transport.

[0008] Further, especially when a cargo pallet is carried into a dry container via one opening in the longitudinal direction, the cargo pallet is transported straight (with straightness). Is required. In other words, if the cargo pallets are not transported straight to the dry container, the following problems (1)-(3) will occur.

 (1) Cargo pallets are loaded in an inclined state in the dry container, and when the cargo is unloaded, the cargo pallets rub against the inner walls of the dry container (frictional contact), and the cargo pallets are unloaded. Becomes extremely difficult.

 (2) If multiple cargo pallets are sequentially loaded into the dry container by multiple loading operations, for example, two cargo pallets equivalent to 20 feet are transported twice in a 40-foot dry container. When loading sequentially in the work, if the first cargo loading pallet (the cargo loading pallet delivered to the back of the dry container) is loaded in an inclined state, the second cargo loading pallet is in front of the H dry container. Loading pallet carried into the side (opening side) cannot fit inside the dry container.

 (3) The cargo loading pallet collides with the inner wall of the dry container, and the cargo loading pallet and the inner wall of the dry container are damaged.

 In addition, when the pallet is 1 alone, when combined with 2 or more pallets, if the pallet is approximately the same as the plane shape inside the transport container, the pallet is The work of fixing and releasing the pallet can be minimized.

 In addition, the pallet includes a pallet main body, a placing section, and a leg section, and the placing section is supported movably along a horizontal plane and can be positioned at a predetermined position. In the case of having a conveyed object, it can be fixed in accordance with a conveyed object having various outer shapes (especially, a press die or the like). As a result, for example, railway transportation of press dies, which has been extremely difficult in the past, can be realized.

 Further, in the case where the transporting object fixing tool is supported via an elastic tool, the transported article is transported to a transported article (particularly, a measuring device for a press die) fixed by the transporting article fixing tool. The influence of vibration, impact, etc. can be suppressed. As a result, for example, railway transportation of press dies, which has been extremely difficult in the past, can be realized.

 When the transport container is placed on the chassis of the vehicle, the transported object can be transported more efficiently than when the transport container does not need to be placed on the floor.

 BEST MODE FOR CARRYING OUT THE INVENTION

 [0015] 1. Conveyance device for conveyed goods

 A transporting device for a transported object according to the present invention includes a base member, a traveling unit, a pallet supporting member, and a lifting / lowering operation unit described below, and can transport the transported item via a pallet to a transport container. It is like that. The transfer device can include, for example, one or more of a contact unit, a remote control unit, a guided unit, a connecting unit, an engaging unit, and a connection releasing unit, which will be described later. .

 [0016] The structure, size, material, and the like of the "transport container" are not particularly limited as long as a pallet on which a load is loaded (hereinafter, also simply referred to as a load pallet) can be stored. This transport container usually has a rectangular floor surface, and its longitudinal direction is set as the transport direction of the transported object. Examples of the transport container include a dry container, a reefer container, an open top container, and a flat container. Of these, dry containers and reefer containers are preferred. This is because it is the most distributed, cheap and easy to secure. This dry container usually has a rectangular floor surface and has an opening formed at one end in the longitudinal direction. When transported by a transport device described later, this transport container can be placed on a chassis of a vehicle such as a truck, or removed from the chassis and placed on the floor.

[0017] The type, size, weight, and the like of the "transported object" are not particularly limited as long as they can be stored in a transport container via a pallet. Examples of the type of the conveyed object include dies, machine tools, automobiles, automobile parts, electric products, concrete piles, precast concrete, fruits, miscellaneous goods, and the like. Examples of the conveyed product include a plate-shaped product, a coil-shaped product, a long product, a bar-shaped product, and a lump product. these Examples of the material of the product include steel, stainless steel, aluminum, plastic, glass, stone (eg, tombstone), and wood. The weight of the conveyed object is, for example, about 100 kg to 50 tons. Generally, it is about lton-20ton. When the conveyed product is a coil-shaped product formed by winding a band-shaped material or a wire-shaped material, the axis of the coil-shaped product is perpendicular to the transport direction (longitudinal direction) of the transport container. It is preferable to be stored in a transport container. This is because when the transport container is transported, it is possible to prevent the roll of the coiled product from jumping out in the transport direction.

 [0018] The structure, size, material, and the like of the "pallet" are not particularly limited as long as a conveyed object can be loaded. This pallet, for example, when it is 1 alone or when combined when it is 2 or more, can have a size substantially equal to the size of the planar shape inside the transport container. In this way, if the pallet is modularized (standardized) based on the length of the transport container floor in the longitudinal direction, the work of fixing and releasing the pallet from the transport container is minimized. It can be.

 Here, the above-mentioned “if the case of (1) is used alone, and the case of (2) or more, when they are combined, the size almost matches the size of the plane shape inside the above-mentioned shipping container” means that the bottom surface of this pallet is When considered to be a shape, the shape and size can be approximately the same as the bottom surface of the shipping container. Further, the bottom shape obtained by combining two or more main pallets of various sizes and shapes can be a shape and a size that substantially match the transport container. In a pallet used in combination, for example, the shape of the pallet is such that the long side (or short side) of the floor of the transport container is divided into two, three, four, five, etc. can do. Similarly, the floor surface may be combined with a pallet having a size such as 1Z6, 2/6, or 3Z6, or a pallet having an unequal size such as 2Z5, 3/5, or the like. In addition, a pallet that has a size such as a floor that divides the long side direction into three equal parts and the short side direction into two equal parts, that is, a pallet that separates both directions in the long side direction and the short side direction, is used. They may be combined.

[0019] Further, the pallet is, for example, a pallet main body, a mounting portion provided on the upper side of the pallet main body for mounting and supporting the conveyed object, And a leg portion to be grounded, and a lower open space can be formed below the pallet main body, at least one of which is open below and on one side. this For example, (1) a configuration having a plurality of band fixing holes provided at positions along a flat outline of a plurality of plate-like (or lump) conveyed articles having different planar shapes, (

2) A pair of opposed slopes that can support the coiled product in contact with its outer peripheral surface (see Fig. 10). (3) Restrict the movement of a plurality of long products in the longitudinal direction. (See FIGS. 37 and 38), and (4) a configuration having a goods fixing tool that is supported movably along a horizontal plane and can be positioned at a predetermined position (see FIGS. 32 to 34). Reference) and the like. Here, the mounting portion of the pallet in the above-described (4) mode is composed of, for example, a plurality of lower base materials and a plurality of upper base materials provided orthogonally to the upper surface of the lower base materials. The side substrate is provided with a substrate fixing tool for fixing the upper substrate movably along the longitudinal direction, and the upper substrate is provided with a transport object fixing tool movably along the longitudinal direction. Can be. Accordingly, it is possible to fix a transported object having various external β shapes (especially, a press die or the like). In this case, it is preferable that the upper and lower substrates or the lower substrate are supported by the above-mentioned conveyed object fixing device via an elastic member (for example, a rubber member, a panel, a buffer mechanism or the like). As a result, it is possible to suppress the influence of vibration, impact, and the like at the time of transportation on a transported object (particularly, a measuring device for a press die) fixed by the transported object fixing tool. In addition, examples of the fixing tool include a screwing tool, a clamp tool, and a hook tool.

 The lower open space is used, for example, mainly as a space for inserting the transfer device or a part thereof, and is a space for fixing a fixing member for fixing the conveyed object to the mounting portion. The above-mentioned "at least one side is open" does not necessarily mean that all of the directions need to be open. In other words, it only needs to be open in one of the directions of “front”, “rear”, “right” and “left”. That is, for example, the “lower open space” may be configured such that only “lower” and “rear” are open.

In addition, the pallet can further include, for example, a connection / disconnection unit that connects / disconnects the pallet main body and a pallet main body of another pallet. Thereby, connection or non-connection of a plurality of pallets can be appropriately selected according to the type (for example, size, shape, etc.) of the conveyed object. In this way, a versatile pallet corresponding to various types of conveyed goods can be provided. As this connection form, for example, those utilizing screwing, fitting, engagement, connection, pinching, and the like can be cited. This connection / disconnection means can be arranged, for example, at a corner of the mounting surface of the pallet body for the transported object. As a result, the connection workability can be improved, and the space efficiency of the loading surface of the conveyed object can be improved.

 [0021] The pallet may have, for example, a pallet-side guided portion guided by a guide means described later. The pallet-side guided portion can have, for example, one or a combination of two or more of a rotating roller, a rolling ball, a guide surface, and the like.

 The structure, size and the like of the “base member” are not particularly limited. The base member can have, for example, a substantially U-shaped vertical cross section. Further, the base member can be formed to extend, for example, along the transport direction of the transported material (the longitudinal direction of the transport container). In this case, it is preferable that a plurality (preferably, a pair of right and left) is provided side by side. This is because a lightweight and high-strength structure can be obtained. In particular, it is preferable that the planar shape of the base member is substantially the same as the planar shape of the pallet support member described later.

The “traveling means” is not particularly limited in its structure, traveling mode, and the like, as long as it is provided on the lower surface side of the base member and can travel on the floor surface. This traveling means is a means for reciprocating the transport device in the transport direction of a predetermined transported object (longitudinal direction of the transport container). Further, as the traveling means, for example, (1) a form having a rolling member rotatably supported on the lower surface side of the base member, (2) the rolling member, and driving the rolling member A form having driving means (for example, an air motor or the like) can be given. From the viewpoint of being more inexpensive and simpler, it is preferable that the above-mentioned (1) is provided without any means for driving the rolling members. In the above-mentioned mode (1), usually, an external force is applied to the transporting device or the pallet on which goods are to be conveyed by a cargo handling means or manually, and the transporting device travels on the floor via the rolling members. It becomes. Further, in the above-described (2) mode, for example, the transporting device can be moved on the floor surface by the rolling member driven by the driving means. However, the transporting device and the transporting device are assisted by the loading and unloading means or manually. The loading device may be configured to run on the floor surface by applying an external force to the pallet. The rolling members include, for example, rotating rollers, rolling balls, rotating wheels, endless belts, and the like. be able to. Of these, a large number of rotating rollers are preferred from the viewpoint that a lightweight and high-strength structure can be obtained.

 [0024] The structure and support form of the "pallet support member" are not particularly limited as long as it is provided on the base member so as to be able to move up and down and can support the pallet from below. The pallet support member usually has a pallet support surface that contacts the lower surface of the pallet. The pallet support member may have, for example, a substantially U-shaped vertical cross section. Further, the pallet support member can be formed to extend, for example, in the transport direction of the transported material (the longitudinal direction of the transport container). In this case, it is preferable that a plurality (preferably, a pair of right and left) is provided side by side. This is because a lightweight and high-strength structure can be obtained. In particular, it is preferable that at least one end of a plurality of pallet support members arranged side by side be mutually connected via a connecting member! /.

 Further, the pallet support member can be modularized (standardized) based on, for example, the length in the longitudinal direction of the floor surface of the transport container. Thus, the above-mentioned modular pallet can be favorably supported by the pallet supporting member.

 The structure of the “elevating operation means” is not particularly limited as long as the pallet support member can be elevated and lowered. The lifting / lowering operation means lowers the pallet supporting member in an ascending state during traveling by the traveling means, places the pallet supported by the pallet supporting member on a floor surface, and stops the traveling. It is composed of Thus, the traveling of the transport device can be stopped by the grounding of the transported product loading pallet on the floor surface. As a result, it is possible to easily position and load the conveyed product loading pallet, that is, the conveyed product at an accurate transfer position. Examples of the elevating means include an expansion / contraction mechanism, a jack mechanism, a link mechanism, a gear mechanism, and a cylinder mechanism.

The elevating means is provided between the base member and the pallet support member and expands / contracts and expands / contracts when a fluid {usually, gas (particularly, air, etc.)} is supplied and discharged. A pipe for communicating the expansion / contraction member with the fluid supply source, and an opening / closing valve mechanism provided in the middle of the pipe and capable of supplying and discharging fluid to and from the expansion member can be provided. Thus, a heavier transported object can be raised and lowered, and the transported object can be positioned at a more accurate transport position. Here, the expansion / contraction member is, for example, a tubular member. be able to. Further, the pipe may have, for example, one end connected to the expansion / contraction member and a connection connected to another pipe connected to the fluid supply source at the other end. This connection portion can be disposed, for example, on the end surface side in the transport direction of the base member and z or the pallet support member. This makes it easy to connect the pipes.

 Further, the opening / closing valve mechanism may be constituted by, for example, one or more opening / closing valves. Examples of the open / close knob include a valve having an operation unit such as a push button and a roller, an electromagnetic valve, and the like. Further, the opening / closing valve mechanism may have, for example, a fluid discharge contact valve and a Z or fluid discharge operation valve described below. The fluid discharge contact valve is provided at a contact portion described below and contacts a stop member described later to switch its flow path to discharge the fluid supplied to the bulging member. The fluid discharge contact valve may switch its flow path by an operation of an operator to discharge the fluid supplied to the bulging member. The fluid discharge operation valve is provided in a remote control unit to be described later, and switches its flow path by a fingertip operation (for example, a push button operation, a lever tilting operation, etc.) to supply the fluid supplied to the bulging member. Is to be discharged. From the viewpoint that safety can be further improved, it is preferable that the opening / closing valve mechanism has both the fluid discharge contact valve and the fluid discharge operation valve. Further, the opening / closing valve mechanism may have, for example, a fluid supply operation valve for switching the flow path by a fingertip operation to supply the fluid to the bulging member.

The structure, the contact form, the number, the shape, and the like of the “contact portion” are not particularly limited as long as the contact portion can contact a stove member described later. The contact portion may have a detection sensor for detecting the contact when the contact portion comes into contact with the stopper member, for example. Thus, the pallet support member can be automatically lowered by the lifting / lowering operation means based on the detection signal of the detection sensor. Further, the contact portion may have, for example, the above-mentioned fluid discharge contact valve. Accordingly, based on the switching of the flow path of the fluid discharge contact valve, the fluid supplied to the bulging member is discharged, and the pallet supporting member can be automatically lowered. Further, the contact portion includes the fluid discharge contact valve and the fluid discharge valve. And a guard member surrounding the outer periphery of the contact valve. Thereby, the operability of the fluid discharge contact valve can be improved. Further, this contact portion can be disposed, for example, on the end face side in the transport direction of the base member and the Z or pallet support member. Thus, the contact portion and the stopper member can be more reliably brought into contact with each other. In particular, it is preferable that a plurality of (preferably, a pair of right and left) contact portions are provided along the width direction of the transfer device (a direction orthogonal to the transfer direction).

 The structure, arrangement position, number, shape, and the like of the “storage member” are not particularly limited as long as they are provided corresponding to predetermined traveling stop positions of the transfer device. The stopper member restricts travel of the transfer device by contact with the contact portion. Further, the stove member can be provided, for example, on the opening side of the transport container. As a result, as described in the unloading method described later, it is possible to convey the conveyed object without using an expensive stage having a leveling mechanism. In this case, the stopper member is preferably attached to a corner fitting on the opening side of the transport container. This is because the stud member can be easily attached and detached using the corner fittings already installed in the transport container (especially the container). The above-mentioned corner fittings are used to fix the transport container to the chassis, to fix the transport containers to each other in the ship, and to pick up by a crane or a gantry crane. It is a metal fitting that has been installed. Further, the stove member may be provided, for example, on a stage adjacent to the opening side of the transport container. Thereby, a heavier, longer, bulkier conveyed object can be conveyed using the stage. Further, the stove member can be fixed to, for example, the inner wall surface or the floor surface of the transport container. Further, the stove member can be constituted by, for example, the inner wall surface of the transport container (particularly, the inner wall surface on the back side).

Further, as the stopper member, for example, (1) a base portion having substantially the same length as the lateral width of the transport container, and screw fixing portions provided on both ends of the base member and screwed to corner fittings of the transport container. And (2) a base portion having a length substantially equal to the lateral width of the transport container, and a stopper portion provided on both ends of the base member. Examples include a form having a fixing portion that can be fixed to both side walls of the container, and a stopper piece provided at a predetermined position in the longitudinal direction of the base member. Wear.

 [0028] The structure, shape, control operation, and the like of the "remote control unit" are not particularly limited as long as it is a part for controlling various operations of the transfer device at a location remote from the transfer device. The control operation includes, for example, a raising operation of the pallet supporting member, a lowering operation of the pallet supporting member, a traveling operation of the traveling means, and the like. This remote control unit can output an operation signal to the elevating / lowering operating means and Z or the traveling means, for example, by wire or wirelessly. It is preferable that the remote control unit has at least one open / close valve connected to the pipe of the lifting / lowering operating means and constituting the open / close valve mechanism, from the viewpoint of being simpler and cheaper. In particular, it is preferable that the open / close valve is the above-mentioned fluid discharge operation valve.

 [0029] The structure and guided state of the "guided portion" are not particularly limited, as long as the "guided portion" can be guided by guide means described later. The guided portion may have, for example, one or a combination of two or more of a rotating roller, a rolling ball, a guide surface, and the like. From the viewpoint of guideability, it is preferable that the guided portion has a rotating roller and a Z or a rolling ball. The guided portion may be provided on, for example, the base member and the Z or Nort support member of the transport device. From the viewpoint of guideability, it is preferable that a plurality of the insides of the case are provided along the conveying direction of the conveyed object.

[0030] The above-mentioned "guidance means" is not particularly limited in its structure, guidance form, and the like, as long as it is provided corresponding to the traveling area. This guide means is a means for guiding the guided part of the transport device and the pallet-side guided part of Z or the pallet. The term "provided corresponding to the traveling area" is not limited to the form provided in the traveling area of the transport device, but may guide the guided part and the Z or pallet-side guided part. As long as this is the case, the form provided at a portion close to the traveling area of the above-mentioned transport device is also included.

[0031] The guide means may be, for example, a guide having a long guide body extending along the transport direction of the transported object. Examples of the vertical cross-sectional shape of the guide body include a U-shape, a C-shape, an H-shape, an L-shape, a rectangular ring, a circular ring, a flat plate, and a different shape. The guide body may have, for example, one or more of a guide surface, a rotating roller, a rolling ball, and the like. From the viewpoint of guideability, Preferably, the guide body has a guide surface. Examples of the arrangement of the guide main body include (1) a form provided on the floor of the transport container, and (2) a floor of the stage adjacent to the opening end of the transport container. And (3) a form provided over the floor of the transport container and the stage. In these cases, the guide body can be placed on the floor, for example, or fixed to the floor by appropriate fixing means (for example, a clamp, a lock, a screw, etc.). . The guide body may be provided, for example, on the inner wall of the transport container.

 [0032] Further, the guide means includes, for example, the above-described guide body, a traveling section for running the guide body, and a lifting / lowering section provided between the guide body and the travel section to raise and lower the guide body. And The guide body includes, for example, a flat floor portion on which the traveling means of the transport device can travel, and a guide wall portion that rises from both side edges of the floor portion and guides the guided portion of the transport device. , Can be provided. Thus, the guide means can be run with the transport device mounted thereon, and the work of installing and removing the guide means can be performed more easily and quickly. In addition, examples of the traveling unit include a rotating roller, a rolling ball, and an endless belt. Further, examples of the elevating unit include a cylinder mechanism, a link mechanism, and the like. From the viewpoint that a simpler and cheaper structure can be obtained, the elevating unit is supported by the guide body so as to be able to move up and down, and the elevating member having the traveling unit is provided between the elevating member and the guide body. It is preferable to have an elastic member (for example, a panel member, a rubber member, or the like) for urging the guide body upward with respect to the member. The urging force of the elastic member is usually set to a value larger than the weight of the guide body and the transfer device. The elevating unit may be, for example, an elevating member which is supported by the guide body so as to be able to ascend and descend and has the traveling unit, and is provided between the elevating member and the guide body, and is a fluid (usually a gas (particularly, And the like, which expands and contracts due to the supply and discharge of}).

[0033] The guide means may be constituted by, for example, the inner wall of the transport container.

The lifting mechanism 86 is driven by the action of the air motor 87. It is composed of a screw jack 88. According to the leveling mechanism 82, when the corner member c2 of the container C and the locking member 83 in the locked state are raised, the container C on the chassis is lifted, and the height level of the floor surface is raised. It will be adjusted.

 First, the container C is transported to a predetermined work place adjacent to the S-stage 80 by the truck. Then, the leveling mechanism 82 matches the height of the floor of the container C placed on the chassis with the height of the floor of the stage 80. Thereafter, the engaging bar 63 of the transfer device 41 is positioned at the cargo handling position b, and the engaging bar 63 is engaged with the claw f of the forklift F to move the transfer device 41 to a desired position on the stage 80. Transfer. At this time, the transport device 41 is disposed such that the connecting member 46a faces the opposite side to the container C. Next, the transport device 41 on the stage 80 is pushed into the inside of the container C by the operator, and the transport device 41 is moved to the transport object loading pallet Pb placed on the floor at the opening cl side of the container C. Into the lower open space Pb4 (see Fig. 41).

 [0086] After that, in the transfer device 41, the air hose 56 is connected to the joint tool 54, and the other end of the wire rope 34 having one end connected to the winch W is engaged with the annular member 48. In this state, when the push button valve 60 is pressed, compressed air is supplied to the expansion / contraction member 52 to expand the expansion / contraction member 52, and the pallet support member 45 is raised. Pb lifts the force on the floor of Container C. Thereafter, when the wire rope 34 is wound by the winch W, the transport device 41 is pulled toward the opening cl side of the container C, and the transported product pallet Pb is moved along with the transport device 41 on the floor of the container C. It travels from the back side to the opening side, and further travels on the floor of the stage 80 (see Fig. 42). When the contact valve 47 of the transfer device 41 contacts the stop member 62 provided on the floor of the stage 80 during the traveling, the compressed air supplied to the expansion / contraction member 52 is exhausted to the outside. As a result, the expansion / contraction member 52 contracts, the pallet support member 45 is lowered, and the transported product loading pallet Pb supported by the pallet support member 45 is placed on the floor of the stage 80. Next, the load Pallet Pb carried out onto the stage 64 is transferred to a desired position by a crane or the like.

After that, the above-described operation (see FIGS. 41 and 42) is repeated to unload the remaining pallets Pb in the container C, thereby completing a series of unloading operations. [0087] (3) Loading operation of the transfer device

 Next, a description will be given of an operation of loading a transported object into the container C, which is used in the transport device 41 having the above configuration.

 In this carrying-in operation, it is assumed that two independent pallets Pb for transporting goods are stored in the container C. In this loading operation, the above-described stage 80 adjacent to the opening cl side of the container placed on the chassis is used. In this transfer operation, the transfer device 41 which does not connect the other lifting units 42c and 42d is used.

First, an empty container C is carried by a truck to a predetermined work place adjacent to the stage 80. Then, the leveling mechanism 82 matches the height of the floor of the container C placed on the chassis with the height of the floor of the stage 80. Thereafter, the engaging bar 63 of the transport device 41 is positioned at the cargo handling position b, and the engaging bar 63 is engaged with the claw f of the forklift F, so that the transport device 41 is moved to a desired position on the stage 64. Transfer to At this time, the transport device 41 is disposed such that the connecting member 46a faces the back side of the container C. Next, the transported product pallet Pb is transported to a desired position where the transported product pallet Pb is covered and covered by the transport device 41 on the stage 80 by a tray or the like, and is transported into the lower open space Pb4 of the transported product pallet Pb. It is assumed that the device 41 has entered.

Then, the wire rope 34 connected to the air hose 56 and the winch W is connected to the transfer device 41. The wire rope 34 is wound around a roller tool 33 provided on the wall on the back side of the container C. In this state, when the push button valve 60 is pressed, compressed air is supplied to the expansion / contraction member 52 to expand the expansion / contraction member 52, and the pallet support member 45 is raised. Pb can also raise the floor force of Container C. Thereafter, when the wire rope 34 is wound up by the winch W, the transport device 41 and the transported product pallet Pb are pulled toward the back of the container C (see FIG. 43). Then, when the contact valve 47 of the transfer device 41 comes into contact with the inner wall surface of the container C during traveling, the pallet support member 45 is lowered, and the conveyed product loaded on the pallet support member 45 is loaded. The pallet Pb is placed on the floor on the back side of the container C. Next, transport device 4 Pull 1 out onto the stage 80 floor (see Figure 44).

 Thereafter, the above-described operation (see FIGS. 43 and 44) is repeatedly performed, and the remaining loaded pallets Pb are loaded into the container C, and the loading operation of a series of loaded products is completed. At the time of loading of the remaining loaded product pallets Pb, the stopper member 62 is fixed to the opening portion cl side of the container C of the loaded loaded product pallets Pb.

(4) Effects of Embodiment 2

 As described above, in the transport device 41 of the second embodiment, a large number of rotating rollers 44 are rotatably supported on the lower surface side of the base member 43, and the pallet Pb can be supported by the base member 43 from below. The member 45 is supported so as to be able to move up and down freely, and an expansion member 52 that expands and contracts by supplying and discharging compressed air is provided between the base member 43 and the pallet support member 45, so that simple cargo handling means such as a forklift and winch can be used. By using the dry container C, a heavy, long, or bulky conveyed product (for example, a press die having a weight of about 420 to 20 tons) can be loaded and unloaded. Further, a contact valve 47 is provided in the middle of the pipe 53 connected to the expansion / contraction member 52 so as to be able to contact the stop member 62 and switch its flow path. When the contact valve 47 contacts the stop member 62, the contact valve 47 expands. The compressed air supplied to the compression member 52 is exhausted to the outside, and the pallet support member 45 is lowered, so that the conveyed object can be accurately conveyed to a predetermined conveyance position (travel stop position). it can. As a result, during the transfer of the load, the load pallet Pb also loses its upper force on the stage 64, or the load pallet Pb violently collides with the back wall of the dry container C or another load pallet Pb. Damage and collapse of cargo can be prevented.

Further, in the transfer device 41 of the second embodiment, it is possible to engage and disengage with a concave portion 49 formed at one longitudinal end of the elevating units 42a and 42b and at the other longitudinal end of the other elevating units 42c and 42d. Since the simple connecting lever 51 is provided so as to be swingable, it is possible to appropriately select connection or non-connection according to the type (for example, size, shape, weight, etc.) of the conveyed object. Further, in the transport device 41 of the second embodiment, the engaging bar 63 is provided so as to be displaceable between the cargo handling position b protruding from the pallet supporting surface 45a and the storage position a immersed from the pallet supporting surface 45a. The transporting device 41 can be easily lifted and transported by the loading means such as a forklift via the engaging bar 63 at the loading position b. Further, in the transport method of the second embodiment, the transported object is transported to the container C by using the stage 80, so that various types of transported objects such as weight, long, bulky, etc. are efficiently transported. it can. Further, since the pallets Pb are modularized based on the floor length of the container C, the work of fixing and releasing the pallets Pb to and from the dry container C can be minimized.

 [0091] The present invention is not limited to the first and second embodiments, but may be variously modified within the scope of the present invention according to the purpose and application. That is, in the second embodiment, the force for transporting the conveyed object to the container C placed on the chassis is not limited to this. For example, as shown in FIG. You may want to transport the goods to C.

 In the second embodiment, the transfer device 41 is provided with the guide rollers 40 at positions guided along the leg portions Pb3 provided on the left and right sides of the pallet Pb. For example, the transport device 41 may be provided with a guide roller 40 '(indicated by an imaginary line in FIG. 24) at a position where it is guided along a leg Pb3 provided at the center of the pallet Pb. Good. Thereby, the straightness of the transfer device can be further improved.

 [0092] In the second embodiment, the leveling mechanism 82 that lifts the container C and adjusts the height level of the floor is illustrated. The force is not limited to this. A leveling mechanism that lowers the locking member to be stopped and pushes down the container to adjust the height level of the floor may be used. Also, the lower corner fitting c on the opening cl side of the container C

The force exemplified in the leveling mechanism 82 using the second method is not limited to this. For example, upper and lower corner fittings on the opening side of the container may be used. Further, it is preferable that a slope (not shown) on which the wheels of the chassis can ride is provided at a position close to the stage 80, and a height adjusting plate (such as an iron plate) is provided on the slope.

[0093] In the second embodiment, the transporting device 41 is caused to travel on the floor surface, or the transporting device 41 or the transported product pallet Pb is transported to a desired position by a cargo handling means such as a forklift or a winch. However, the present invention is not limited to this.For example, the operator may move the transport device 41 on the floor or transfer the transport device 41 or the transported product pallet Pb to a desired position. Can be. In particular, a self-propelled transport device It can be run on the floor.

 [0094] In transporting the press die in the second embodiment, the three-dimensional measuring device is usually transported together with the press die B. In this case, as shown in FIG. 35, a substantially C-shaped base material 69 is fixed to the upper surface of the slit base material 67 constituting the pallet Pb via a fixture 68, and the upper surface of the base material 69 is fixed to the upper surface of the base material 69. If the plate 73 for mounting and supporting the three-dimensional measuring device 71 is fixed via the vibration-proof rubber member 70, the container can be transported using the pallet Pb on which the three-dimensional measuring device 71 is loaded. Thereby, vibration during transportation is absorbed by the vibration-proof rubber member 70, and the adverse effect on the three-dimensional measuring device 71 due to the vibration can be suppressed. As a result, rail transportation of press dies, which was difficult in the past, can be realized. In particular, it is preferable to pack the three-dimensional measuring device 71 with a waterproof sheet material 72 (for example, a material in which a volatile protective agent is coated on the surface of vinyl).

[0095] Further, in the second embodiment, the conveyed material is loaded on the pallet connection body formed by connecting two pallets (1Z4 modular pallets). However, the present invention is not limited to this. The connection or non-connection can be appropriately selected according to the size, shape, weight, and the like of the conveyed object. For example, as shown in Fig. 36, in the case of a bulky conveyed product corresponding to the inner volume of a container, one conveyed product may be mounted on a pallet connection body that connects four pallets. it can. In addition, as shown in FIG. 37, in the case of a conveyed product made of a large number of steel materials slightly longer than the entire length of the container, a receiving member 74 is provided on a pallet connection body connecting four pallets. A conveyed object can be mounted in an inclined state via the receiver 74. In addition, as shown in Fig. 38, in the case of a large number of steel materials that are shorter than the full length of the container, a receiving device 75 is provided on a pallet connection body that connects four pallets, and the receiving device 75 is provided. Via 5, the conveyed object can be mounted in a state where it is prevented from jumping out in the longitudinal direction. In this case, it is preferable that the receiving member 75 is slidably supported by the slide rail 76. Thereby, it is possible to cope with long transported articles of various lengths. Further, as shown in FIG. 38, a composite member 100 such as a square member can be interposed between the left and right side surfaces of the pallet Pb and the left and right inner wall surfaces of the container C. As a result, it is possible to ensure appropriate straightness of the pallet drawn out of the container when unloading. In addition, as described above, when using a pallet with a size substantially the same as the container If the transport unit 41 is configured by connecting the lift units 42c and 42d to the lift units 42a and 42b, the transport device 41 can load and unload the loaded product pallet to the container at one time. .

In the first and second embodiments, the opening / closing valve mechanisms 20, 61 are provided only in the transfer devices 1, 41. However, the present invention is not limited to this, and various operations of the transfer device are remotely controlled. An open / close valve mechanism can also be provided in the remote control unit for this purpose. For example, as shown in FIG. 46, a remote control unit 90 (shown by phantom lines in FIG. 9) is connected to the pipe 13 (or the air hose 16) via another pipe, and the fluid supply to the remote control unit 90 is performed. Operating valve 91, a fluid discharging operating valve 92, and a valve 93 may be provided. Here, the fluid supply operation valve 91 switches its flow path by a push button operation to supply the fluid to the bulging member 12 and raise the pallet support member 5. The fluid discharge operation valve 92 switches its flow path by a push button operation to discharge the fluid supplied to the bulging member 12 and lower the pallet supporting member 5. As a result, (1) the push button valve 19 is operated to push up the pallet support member 5 by operating the push button valve 19, and the contact valve 7 contacts the stop member 32 to lower the pallet support member 5; A mode in which the operation of raising and lowering the pallet support member 5 is remotely controlled by the remote control unit 90 can be appropriately selected at a location distant from 1 (for example, a driver's seat of a forklift). From the viewpoint that the safety can be further improved, it is preferable to use the above-mentioned (1) form and (2) form together.

 Furthermore, for example, as shown in FIG. 47, without providing the contact valve 7 and the push button valve 19 in the transfer device 1, the remote control unit 90 includes a fluid supply operation valve 91, a fluid discharge operation valve 92, and a A valve 93 may be provided.

 Further, in the loading / unloading operation of the first and second embodiments, the connection Z disconnection of the track head (operation driving unit) to the chassis on which the container is placed can be appropriately selected.

 Example 3

 Hereinafter, the present invention will be specifically described with reference to the drawings, using a third embodiment.

In the third embodiment, the other lifting units 42c and 42d are connected to each other in the same manner as in the second embodiment, and the transport device 41 (the size of the floor of container C is approximately 1Z2) is used. Using the container It is assumed that two independent load pallets Pb (see Fig. 60) are to be transported (unloaded Z loaded) to C. A relatively heavy press mold B (for example, about 10 tons) is exemplified as a conveyed product to be loaded on the pallet Pb. In this transport method, a large forklift F (approximately 10t class) that cannot enter the container C shall be used. In addition, this transport method is performed in a state where the container C is mounted on the truck chassis and is adjacent to the opening cl side container 98 {platform (for example, withstand load 5tZm ² )}. And Further, in this transfer method, a transfer stage 99 that can be transferred by a large forklift F is used.

 [0098] (1) The unloading action and effect of the transfer device

 First, as shown in FIG. 48, the container C transported by the truck is transported to a predetermined work place adjacent to the container C force stage 98 in which the loaded pallets Pb are stored, and the landing gear is used to move the container C placed on the chassis. The level is adjusted. Then, the door of the container is opened and the pallet Pb loaded on the floor at the opening cl side of the container C is moved by the large forklift F to a desired position outside the container C. Transfer.

 Thereafter, as shown in FIG. 49, the transfer stage 99 on which the transfer device 41 is mounted on the floor is transferred by the large forklift F to the floor on the opening cl side of the container C. At this time, the floor surface of the transfer stage 99 and the floor surface of the container C are at substantially the same height level. Next, a fixing band (not shown) fixing the transfer device 41 to the transfer stage 99 is removed, and the transfer device 41 is moved by an operator to the floor of each of the transfer stage 99 and the container C. After being moved on the surface, it is pushed into the deep side of the container C, and enters the lower open space Pb4 of the transported product pallet Pb.

 Thereafter, the air hose 56 is connected to the joint 54 of the transfer device 41, and the other end of the wire rope 34, one end of which is connected to the large forklift F, is engaged with the annular member 48. In this state, when the fluid supply operation valve 91 (up button) of the remote control unit 90 (see the phantom line in FIG. 9) is pressed, compressed air is supplied to the expansion / contraction member 52 and the expansion / contraction member 52 is released. The pallet support member 45 is expanded and the pallet support member 45 is lifted, and the pallet Pb to be transported is also lifted by the rising pallet support member 45 on the floor of the container C.

[0101] Thereafter, as shown in Fig. 50, the large forklift F was driven in a direction in which the force of the container C also moved away. Then, the transporting device 41 is pulled through the wire rope 34, and the transported product loading pallet Pb travels along the floor of the container C from the back side to the opening portion cl side together with the transporting device 41. Then, when the transported product pallet Pb is moved to the floor on the opening cl side of the container C, the operator operates the contact valve 47 (or the fluid discharge valve 92 of the remote control unit 90), The compressed air supplied to the expansion / contraction member 52 is exhausted to the outside, the expansion / contraction member 52 contracts, the pallet support member 45 is lowered, and the pallet Pb supported by the pallet support member 45 is moved to the container C. It is placed on the floor at the opening cl side.

[0102] Thereafter, as shown in Fig. 51, the large forklift F transfers the empty transfer stage 99 to the floor on the opening cl side of the force S container c. The transport device 41 is pulled out. Thereafter, as shown in FIG. 52, the large-sized forklift F transfers the load Pallet Pb placed on the floor at the opening cl side of the container C to a desired position outside the container C. , A series of unloading work will be completed

[0103] According to such an unloading method, the transport device 41 and the large forklift F are used for the container C mounted on the truck chassis which cannot be removed from the chassis C of the truck using a large crane or the like and placed on the floor. By using the pallet, the pallet Pb loaded with the relatively heavy press die B can be safely carried out. As a result, railway transportation in press mold containers, which was difficult in the past, can be realized, and depending on geographical factors, transportation time (lead time) can be significantly reduced.

 In the above embodiment, as shown in FIGS. 51 and 52, the transported product pallet Pb is placed on the floor surface on the opening cl side of the container C, and then immediately below the transported product pallet Pb. Force to take out the transported product pallet Pb out of the container C after taking out the transport device 41 in the container C outside the container C, and is not limited to this.For example, as shown in Figs. 53 and 54, After moving the transport device 41 directly below the transported product pallet Pb to the back side of the container C, the large forklift F unloads the transported product pallet Pb to the outside of the container C, and then removes the transport device 41. It may be taken out of the container C.

 [0105] (2) Loading operation of the transfer device

First, as shown in FIG. 55, an empty container C is adjacent to the stage 98 by a truck. It is transported to the designated work place and the level of the container C placed on the chassis is adjusted by the landing gear. Then, the door of the container C is opened, and the transported pallets Pb are transported by the large fork lift F onto the floor at the opening cl side of the container C.

 Thereafter, as shown in FIG. 56, the transfer stage 99 equipped with the transfer device 41 is transferred by the large forklift F onto the floor at the opening cl side of the container C. At this time, the floor of the transfer stage 99 and the floor of the container C are at substantially the same height level. Next, a fixing band (not shown) for fixing the transfer device 41 to the transfer stage 99 is removed, and the transfer device 41 is pushed by the operator on the floor of the container C toward the back side. , And enters the lower open space Pb4 of the pallet Pb.

 After that, the air hose 56 is connected to the transfer device 41, and the pushing member 31 (attachment) is attached to the claw portion f of the large forklift F. In this state, the operating valve 91 (lift button) for the fluid supply of the remote control unit 90 (see the phantom line in FIG. 9) is pressed to raise the knurl support member 45, and the pallet support member 45 moves the transported object. The loading pallet Pb is lifted from the floor of the container C.

 Thereafter, as shown in FIG. 57, when the large forklift F is moved in a direction approaching the container C from a state in which the tip side of the pushing member 31 is in contact with the transfer device 41, the transfer device 41 and the The loaded pallet Pb is pushed into the back of the container C. During the travel, the contact valve 47 of the transport device 41 is operated by the operator, and the pallet support member 45 is lowered. The pallet Pb supported by the pallet support member 45 is moved to the container C. Is placed on the floor on the back side of the.

 Next, the air hose 56 connected to the transfer device 41 is removed, and then, as shown in FIG. 58, the empty transfer stage 99 is moved by the large forklift F onto the floor at the opening cl side of the container C. The transfer device 41 is drawn out onto the floor of the transfer stage 99. After that, as shown in FIG. 59, the large pallet Pb is transferred by the large forklift F onto the floor at the opening cl side of the container C, and a series of loading operations is completed.

[0110] According to such a loading method, the chassis force of the truck is increased by using a large crane or the like. For the container C mounted on the truck chassis that cannot be removed and placed on the floor, the transport device 41 and the large forklift F are used to safely transfer the pallet Pb loaded with the relatively heavy press die B to the container C. Can be brought in. As a result, railway transportation in press mold containers, which was difficult in the past, can be realized, and depending on geographical factors, transportation time (lead time) can be significantly reduced.

 In this embodiment, as shown in FIG. 60, two pallets (two or more pallets each having a size of approximately 1Z4 on the floor of the container) connected by a connecting member 97 (for example, a clamp). The Pb is stored in a container, and the pallet connected body Pb is loaded with a pressing die (for example, about 1 Ot). The force is not limited to this. For example, as shown in FIG. A pallet may be stored in each of the pallets at both ends in the longitudinal direction of the pallet C, and the pallet connector Pb may be stored between the pallets. Here, for example, a relatively lightweight press die (for example, about 3 tons) is loaded on each pallet, and a relatively heavy press die (for example, about 10 tons) is mounted on the pallet link Pb. Can be loaded. In this case, the conveyed article-loaded pallet linked body Pb is conveyed by the conveyer 41, and the conveyed article-loaded pallet is conveyed by the conveyer 41 or a small forklift that can enter the container C. Further, as shown in FIG. 62, even if two press dies (for example, about 3 tons) are loaded on each of the two pallet linked bodies Pb, each transported article is loaded by the transport device 41. Pallet linked body Pb can be transported. Further, as shown by phantom lines in FIGS. 60-62, a state in which the pallet linked bodies Pb are connected to each other and the pallet linked body Pb and a single pallet are connected by the connecting tool 97a, that is, the pallet linked body Pb has substantially the same size as the container floor surface. Container transportation can be stably performed in a state where the pallet assembly as described above is stored in the container. In this case, for example, when loading a pallet loaded with goods, use a pallet linkage almost the same size as the floor of the container, and complete the loading once efficiently while ensuring straight-line stability. Therefore, when unloading the pallets loaded with goods, it is also possible to remove the connecting member 97a and unload a plurality of pallets loaded with goods.

In the third embodiment, the operator operates the contact valve 47 and the like to lower the transported product pallet Pb together with the pallet support member 45.However, the present invention is not limited to this. A stopper member 32 is provided in the same manner as in Examples 1 and 2, and the stopper member 32 is The loaded pallet Pb may be lowered together with the pallet support member 45 by contact with the contact valve 47. Thereby, safer transport can be realized.

 Further, in the third embodiment, an example in which the transfer is performed using the stage 98 (platform) is described. However, the present invention is not limited thereto. For example, the large forklift F and the large forklift F that move on the ground without using the stage 98 may be used. A transport stage 99 may be used to transport the transported object to the container C. Furthermore, as described above, the transported object may be transported to the container C further placed on the floor without using the stage 98.

 Further, in the first and third embodiments, the force for adjusting the horizontality of the container C placed on the chassis by the landing gear when the pallet is loaded is not limited to this. The conveyance may be performed without using the landing gear. In the third embodiment, the transport is performed with the track head (driving drive) connected to the chassis. However, as in the first and second embodiments, the transport of the track head (driving drive) is performed. Connection Z disconnection can be appropriately selected.

 Example 4

 [0112] Hereinafter, the present invention will be described in detail with reference to the drawings using Example 4.

 In the fourth embodiment, as a “transport container” according to the present invention, as shown in FIG. 63, a 40-foot dry container C (hereinafter simply referred to as a “container”) having an opening portion cl at one end in the longitudinal direction. Container C).) Further, as a “pallet” according to the present invention, a pallet connector 100A formed by connecting two pallets 100 and 100 modularized to have a length of approximately 1Z2 in the longitudinal direction of the container C is used. For example. Further, as the “transported object” according to the present invention, heavy cargo, long cargo, bulky cargo, and the like loaded on the pallet assembly 100A are exemplified. Further, as the “transport device” according to the present invention, two right and left transport devices 101, 101 capable of transporting the pallet linked body 100A loaded with the transported object are exemplified. Each transport device 101 has substantially the same configuration as the transport device 41 described in the second embodiment, and the same components are denoted by the same reference numerals and detailed description thereof will be omitted.

 [0113] (1) Configuration of transfer device

In the transport device 101 according to the fourth embodiment, as shown in FIG. 64, the left and right side surfaces of the pallet support member 45 are provided with projecting pieces 102 projecting outward. Each protruding piece 102 has A guide roller 103 (shown as a “guided portion” according to the present invention) guided by a guide tool described later is rotatably supported around a vertical axis. Each of the guide rollers 103 is provided in a plurality (four in FIG. 63) along the transport direction Q of the transported object in one transport device 101.

 [0114] Next, the configuration of the guide tool 105 (exemplified as "guide means" according to the present invention) used in Embodiment 4 will be described.

 As shown in FIGS. 63 and 64, the guide 105 has a guide body 106 having a long shape and a substantially U-shaped vertical cross section extending along the transport direction Q of the transported object. As shown in FIG. 66, the guide body 106 includes a flat floor portion 106a on which the rotating roller 44 of the transfer device 101 can run, and a right and left side edge of the floor portion 106a. The guide roller 103 includes left and right guide walls 106b for guiding the guide rollers 103, and left and right horizontal walls 106c extending outward from the upper edge of each guide wall 106b.

 [0115] A plurality of support members 107 are fixed at predetermined intervals along the transport direction Q on the lower surface side of each of the horizontal wall portions 106c. An elevating shaft 108 is supported by a through hole 107a formed in each support member 107 so as to be able to move up and down. An elevating member 111 that rotatably supports a rolling ball 110 (exemplified as a “traveling portion” according to the present invention) for traveling on the floor is connected to a lower end of each elevating shaft 108. ing. A panel member 112 (illustrated as the “elastic member” according to the present invention) between each lifting member 111 and each supporting member 107 for urging the guide body 106 upward with respect to the lifting member 111. Is interposed. The urging force of the panel member 112 is set to a value larger than the total weight of the guide body 106 and the transport device 101. Accordingly, in a state where only the transfer device 101 without the conveyed article-loading pallet 100A is mounted on the floor portion 106a of the guide main body 106, the floor body force of the plan body 102 is also reduced by the urging force of the panel member 112.
