Description

  The present invention relates to an article conveying conveyor, and more particularly to an automatic lifting mechanism for a conveyor.

  Generally, in a merchandise distribution base that performs merchandise collection and delivery, when a large quantity of merchandise is shipped, a conveyor transport device is used to pick and sort merchandise by destination. Since there are a large number of types and numbers of goods, a large number of conveyor lines are densely installed as individual lines or parallel lines in the site of a vast product collection and distribution center. In addition, the flow of goods by the conveyor is often arranged with individual conveyors connected from the upstream to the downstream of the conveyor so as to promote workability and a smooth flow of conveyance.

  In general, the vast site space of a merchandise collection and distribution base is occupied by such a conveyor with high density, but at the merchandise collection and delivery base, picking and sorting operations by conveyor transport are various. Needless to say, it requires a lot of work. In order to effectively utilize the site space of a vast merchandise collection and delivery base, it is an important issue to make it possible to use the space occupied by the transfer conveyor in combination for other work.

  When the amount of work such as picking and sorting is reduced, if other work or other work is performed on the same floor, it is necessary to remove the heavy conveyor line to secure site space. Removing conveyor lines connected mechanically with sufficient strength to ensure certainty in terms of safety, transport quality, speed, etc., temporarily or as needed, can result in significant work and time and cost loss It is not a realistic response.

  If there is a simple technique and method for sequentially removing and re-installing a large number of heavy conveyor conveyors as needed, picking operations and other operations that require conveyor lines can be performed at the same collection and delivery site. It can be carried out using the floor, and the work and utilization efficiency of the floor can be dramatically improved.

  In order to lift and install a long and sturdy heavy conveyor for transportation in a ceiling direction, it must be lifted by a crane and then securely installed and fixed. Various techniques have been studied for crane lifting and fixing with hooks and wires. In patent document 1, in the structure of the hook in the wire tip of a crane, the technique of the mechanism for attaching / detaching a hanging article is comprised.

  The same applies to Patent Document 2, which discloses a technique that contributes to the attachment / detachment of articles and the fixing / detachment of the hook part itself in the mechanism of the hook part of the crane. However, all these references are made only by making technical improvements to the structure of the hook part. However, in order to safely and temporarily fix a heavy and large device such as a transport conveyor to a high place by lifting it with a crane, it is very dangerous only by fixing the hook with a chain or roller chain or wire. Has not reached the technology to present sufficient countermeasures.

  The present invention has been made in order to solve such problems.

  To temporarily remove the conveyor for installation, which is installed in a vast space at the product collection and delivery site, temporarily lift the conveyor itself to a high place using a crane or the like and place it in a safe standby state. Is most preferred.

  In general, conveyor transportation of goods in a distribution base is performed by first loading the goods that have been received or received into the conveyor line, and then gradually transporting them to a lower position according to the flow or branching of the conveyor line. There are many. Among them, inclined conveyors are often used to convey articles from high places to low positions. The high part of such an inclined conveyor has enough room to carry out other operations under it, for example, the lower part on the other side of this inclined conveyor is lifted by a lift. If the raised conveyor can be automatically fixed and held safely at the ceiling, the space of the installation section of the inclined conveyor can be used for other operations.

  The present invention provides a holding mechanism for safely and stably holding an inclined conveyor lifted by an overhead crane in a hollow portion of a ceiling with a simple operation, and can be easily used when hanging an inclined conveyor. It is an object to develop a detachable holding mechanism for releasing the holding mechanism and re-installing the floor surface.

  While holding a heavy conveyor on one side to the conventional upstream high-conveyance part, hang the low part on the other side of the conveyor, securely fix it to the ceiling, and sequentially convey the conveyor when necessary. It is necessary to be able to suspend and reconstruct and utilize as a conveyor transport line.

In order to solve such a problem, the lifting and lowering device with an automatic detachment mechanism according to the present invention,
Inclined conveyors singly or connected in the article transport conveyor line;
Moving means for allowing the inclined conveyor to move upward in order to provide a working space below the inclined conveyor;
It has a feature in that it has a moving / fixing mechanism for the inclined conveyor comprising fixing means for moving and fixing the inclined conveyor upward by the moving means.
The lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention specifically includes an inclined type conveyor that is singly or connected in an article conveying conveyor line, a lifting mechanism unit laid on the inclined type conveyor, and the lifting mechanism. A hooking hook mechanism part of the part, a fixed tip part of the lifting mechanism part of the inclined conveyor, which is a hinge structure that can be rotated in the vertical direction, and connected to the lifting mechanism part from the ceiling direction An apparatus for lifting the inclined conveyor in a single-supported form, and a ceiling hanging metal fitting mechanism section for hanging and fixing the hanging hook mechanism section of the lifting mechanism section at a ceiling section, the hanging hook mechanism section Has a hook part structure, so that the ceiling hanging bracket can be automatically latched and unlocked.

  In the lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention, the hook portion is a release plate that is rotatable within a certain range, and automatically holds and releases the ceiling hanging bracket and the hook portion. It is characterized by being a release plate that can be used.

  According to the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to the present invention, an inclined conveyor in a heavy and large article conveying conveyor line is lifted in the vicinity of the other end by a hoisting machine (a lifting / lowering machine) while being supported on one side. Can be removed easily and safely. In addition, the inclined conveyor can be installed again by performing the reverse suspension activation when necessary.

  The inclined conveyor preferably has a lifting mechanism portion with a hook structure for lifting near the lower end, and the ceiling is connected to the upper portion of the lifting mechanism portion via a chain or a roller chain or a wire. It is lifted by a crane laid in the section. However, the lifting mechanism is provided in the vicinity of the lower end of the inclined conveyor, but the position may be a substantially intermediate portion of the inclined conveyor, and the present invention limits the position. is not.

  A solid, preferably rod-shaped ceiling hanging bracket is laid on the ceiling, and the hooked portion installed on the upper part of the lifting mechanism is hooked to secure the lifted inclined conveyor safely. Temporary installation is possible. What is necessary is just a form which is a ceiling hanging metal fitting and the hook of a lifting mechanism part is hooked safely and reliably.

  The hook portion of the lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention has an inclined portion at the head in the shape thereof, and the hook portion is automatically moved by abutting the rod-like ceiling hanging bracket on the inclined portion of the head. Inclined and has a structure in which the ceiling hanging metal fitting is automatically latched to the hook portion as the inclined conveyor rises. (See FIG. 3) This structure is hereinafter referred to as a “hook structure”. The mechanism portion having a hook structure is referred to as a “hook portion”.

  Although the present invention does not limit the number of hook portions, the description will be made on the assumption that there are a total of two hook portions in a balanced manner on the left and right sides of the conveyor because it is a mechanism for hanging an inclined conveyor. . Of course, it is sufficient if there are one or more hook portions.

  The hook part of the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to the present invention has a substantially triangular rotating plate that can rotate in the vertical direction at the handle part under the hook. Hereinafter, it is referred to as a “release plate” and is a structure included in the hook portion. When the inclined conveyor is suspended, the hook portion must be automatically removed from the ceiling hanging bracket. At this time, the inclined conveyor is temporarily raised by a lifting device such as a crane. At this time, the ceiling hanging metal fitting is automatically detached from the hook and returned to the inclined portion of the hook portion head by being brought into contact with the inclined portions of the two sides of the release plate. That is, in order to prevent the hook from being blocked by the substantially leading end of the two-side inclined portion of the release plate coming into contact with the lower end of the head inclined portion of the hook portion, the ceiling hanging bracket is prevented from being hooked again on the hook. In addition, the movement of releasing the hook becomes possible. The inclined conveyor is suspended downward by the crane from the time when the ceiling hanging bracket moves from the upper inclined portion to the lower inclined portion of the two inclined portions of the release plate. In FIG. 4, the release plate is described as a substantially triangular rotating plate. However, the release plate may have other shapes as long as it can function as a release plate as described herein. The shape of the release plate is not limited to a substantially triangular shape.

  When the release plate of the hook part is brought into contact with the ceiling hanging metal fitting, the hook part is inclined and guided to release the hook. All the movements of the hook portions described above do not require power, and are automatically performed only by the raising and lowering operation of the inclined conveyor by the device that lifts from the ceiling. Such a structure that exhibits the function of automatically hooking and releasing the hook portion to the ceiling hanging bracket of the inclined conveyor is defined as the hook portion structure of the present invention. The hook part structure is a concept including a similar structure having the same function, and these are included in the present invention.

  The lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention is also characterized by a hinge structure in which the connecting portion of the lifting mechanism and the inclined conveyor is rotatable.

  The lifting mechanism having the hook is connected to the inclined conveyor, but the connecting structure has a hinge structure that allows the lifting mechanism to rotate with respect to the conveyor flow direction. When hooks are hooked to and released from the upper suspension fitting, it is possible to simultaneously cope with the inclination movement of the hook portion due to the ceiling suspension fitting contact. In this case, it is not necessary to have a pivotable hinge structure in joining the hook part and the lifting mechanism part. This leads to structural reinforcement of the entire lifting mechanism.

  However, the present invention does not preclude a hinge structure that can rotate at the joint between the hook portion and the lifting mechanism portion.

  The lifting mechanism of the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to the present invention is an automatic locking structure of a lifting mechanism laid on an inclined conveyor, its connecting mechanism, and a hanging hook mechanism for a ceiling hanging bracket and a rod-shaped bracket. It reaches. However, the detailed shape, size, and material of the lifting mechanism section, hook section, release plate, ceiling hanging bracket, etc. are not limited to the contents of one embodiment described later, and the functions described in detail are in the invention. It is the essence. In addition, it goes without saying that the positions of the hook part and the hanging bracket can be established upside down.

  According to the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to the present invention, the inclined conveyor in the heavy and long article conveying conveyor line can be safely and simply by lifting the vicinity of the other end with, for example, a crane in the state of one side indication. Can be removed. In addition, the inclined conveyor can be installed again by performing the reverse suspension activation when necessary. These can be automatically and safely performed by the hook mechanism of the hook portion included in the lifting mechanism portion. The technical means for effective use of the site floor at the merchandise collection and delivery base can be presented.

  According to the present invention, while a heavy conveyor with a heavy weight is fixed to a conventional upstream high-conveyance section, the lower section on the other side of the conveyor is suspended and automatically and safely suspended on the ceiling section. It can be fixed, and when necessary, the conveyor can be hung up and down again, and it can be constructed and used again as a conveyor transport line.

  And, in the product delivery base having a large number of article transport conveyor lines, the inclined conveyor that is a part of the transport line can be removed or re-installed as needed, so the selection of the site floor of the product collection base The way of effective use can be opened, and it can contribute to the dramatic improvement of effective use. In addition to safety lifting of heavy conveyors on the ceiling, not only ensuring the safety of the site floor, but also a product that can dramatically improve the work efficiency of workers and also improve economic efficiency. A distribution base or a distribution base is realized.

It is the conceptual diagram which showed the aspect by which the hook part of the lifting raising / lowering apparatus with an automatic attachment or detachment mechanism which concerns on one Embodiment of this invention was cancelled | released from a rod-shaped metal fitting.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and the range necessary for the description of the relevant part of the present invention will be mainly described. According to a known technique.

  FIG. 1 is a conceptual diagram showing an overall image of a lifting and lowering apparatus with an automatic attachment / detachment mechanism according to an embodiment of the present invention. This figure is an external view of the inclined conveyor as viewed from the side, and shows the state in which the inclined conveyor of the lifting and lowering apparatus with an automatic attachment / detachment mechanism according to one embodiment of the present invention is installed on the floor and an overhead crane. Both are shown in a lifted state. First, the inclined conveyor 11 installed on the floor surface is installed on the floor surface 13 whose left side is the high end and the right end is the low in FIG.

  For example, the following description will be given on the assumption that articles conveyed by the conveyor are conveyed from the high end to the right low end by the inclined conveyor 11. However, there are cases where the low part of the inclined conveyor is upstream in the conveyance of the article and the article is conveyed to the high part of the inclined part, but it goes without saying that both cases can be handled in the present invention. The height of the inclined conveyor is connected to the upstream conveyor, and the height difference is often sufficiently higher than the height of a person.

  The downstream low part is connected to another downstream conveyor, and the inclined conveyor shown in the figure is positioned as a conveyor that performs inclined conveyance, which is a part of a series of conveyance conveyors. Since the lower part of the inclined conveyor is located on the floor, it can be used by humans. A lifting mechanism 20 is laid in the vicinity of the lower end on the downstream side of the inclined conveyor. Although a lifting device such as a crane is installed on the ceiling portion 14, the illustration is omitted. In the following description, the lifting device is an overhead crane. The crane is near the lifting mechanism 20 of the inclined conveyor 11.

  As shown in FIG. 1, a lifting chain 16 is connected to an overhead crane at the upper part of the lifting mechanism 20. The chain 16 is wound up by a crane which is a lifting device, and the inclined conveyor 11 is lifted upward, and is lifted and fixed to the state of the inclined conveyor 12 shown in FIG.

  The high-level upstream side of the inclined conveyor 11 is connected to another upstream conveyor (not shown). Since the connecting portion is connected by a hinge structure that can be rotated and rotated in the vertical direction, the inclined conveyor 12 is rotated by the lifting device when the hinge structure connecting portion rotates even in the lifting operation of the inclined conveyor 12. The single support can be lifted and raised from the vicinity of the lower end. Of course, the hinge structure may be capable of moving in the left-right direction.

  A hook portion (referred to as a “hook-type hook portion”) 30 is laid on the upper portion of the lifting mechanism portion 20 for convenience of explanation of the drawings. At the tip of the ceiling hanging bracket 24 laid downward from the ceiling, there is a rod-shaped bracket 31, which is a mechanism that is hooked by the hook-shaped hook portion 30. In other words, the inclined conveyor 12 is suspended and fixed in the air via the lifting mechanism 20 by the crane chain 16 from the ceiling and the hook-shaped hook 30 hooked to the rod-shaped bracket 31 of the ceiling hanging bracket 24. It will be in the state.

  FIG. 2 is a conceptual diagram showing a lifting mechanism part of a lifting / lowering apparatus with an automatic attachment / detachment mechanism according to an embodiment of the present invention. This figure is the conceptual diagram which looked at the lifting mechanism part 20 from the low place downstream which is the right side of the inclined conveyor of FIG. The lifting mechanism 20 in the figure is lifted upward by a crane chain 16.

  As shown in FIG. 2, the lifting mechanism 20 has a gate shape, for example, and both legs are connected to both side surfaces of the inclined conveyor 12. A chain 16 from the overhead crane 15 is connected to the substantially upper center of the lifting mechanism 20. When the apparatus 15 that lifts from the ceiling operates to wind up the chain 16, the inclined conveyor 12 together with the lifting mechanism 20 is lifted from the floor surface, and is fixed and hollowly fixed near the ceiling. The shape of the lifting mechanism unit 20 is not limited to the portal form.

  As shown in FIG. 2, ceiling suspension fittings 24 are firmly installed from the ceiling on both sides of the lifting device 15 of the ceiling 14. It goes without saying that the lower end portion of the ceiling hanging bracket 24 is a rod-shaped bracket pipe (rod-shaped bracket 31), and has a strength sufficient to withstand the weight of the inclined conveyor 12. On the other hand, hook-shaped hook portions 30 for hanging are laid on both upper sides of the lifting mechanism portion 20, and the hooks of the hook-shaped hook portions 30 are attached to the rod-shaped metal fitting 31 at the lower end of the ceiling hanging metal fitting 24. It is locked up. Here, it is not necessary to limit the number of the hook parts 30 and the rod-shaped metal parts 31. It may be one or more and is technically selected according to the size and weight of the inclined conveyor.

  The inclined conveyor 12 having a heavy weight is lifted from the overhead crane 15 and fixed in a single-supported manner, not only by the chain 16 from the crane 15 but also by the hook-shaped hook portions 30 laid on both sides of the lifting mechanism portion 20. By securing the rod-shaped metal fitting 31 suspended from the ceiling, safer and more reliable fixation can be achieved. Further, the hooking by the hooking hook type hook part 30 also contributes to prevention of the shaking of the inclined conveyor 12 in the hollow state.

  The lower side legs of the lifting mechanism 20 are fixed to the inclined conveyor 12 by a hinge structure 32 that can rotate and rotate. As shown in FIG. 1, the lifting mechanism portion 20 is rotated and rotated at the connecting portion with the inclined conveyor 12 by the lifting and lifting of the inclined conveyor 12, and thus the hinge structure of the foot connecting portion of the lifting mechanism portion 20. The effect which the connection part 32 fulfills is large. The hinge structure 32 also rotates and performs an important function when the hook-shaped hook portion 30 is automatically hooked to the rod-shaped metal fitting 31.

  Next, the aspect in which the hook-shaped hook portion 30 of the lifting mechanism portion 20 is hooked on the rod-shaped metal fitting 31 of the ceiling hanging metal fitting 16 will be described in detail.

  FIG. 3 is a conceptual diagram showing an aspect in which the hook portion of the lifting / lowering device with an automatic attachment / detachment mechanism according to the embodiment of the present invention is hooked to the rod-shaped metal fitting. The figure shows a hook-like hook 30 laid on the upper part of the lifting mechanism 20 by a hinge mechanism that can be rotated and a substantially triangular release laid on the hook-type hook so as to be rotatable. The plate 33 and the rod-shaped metal fitting 31 in the lower part of the ceiling hanging metal fitting are shown. In these descriptions, the “hook-shaped hook portion” and the “substantially triangular release plate” are shape expressions used as an example for easy understanding of the function, and the shapes of the hook portion and the release plate are the same. It is not limited. Any shape that enables the functions described below is included in the concept of the hook and release plate of the present invention.

  FIG. 3 is an external view of the above structure as viewed from the side of the inclined conveyor. In addition, the figure shows the movement from the drawing shown on the left side to the drawing shown on the right side in the order of the arrows until the hook-shaped hook portion 30 and the lifting mechanism portion 20 are hooked on the rod-shaped metal fitting 31. The ceiling hanging bracket 24 is omitted for easy understanding of the drawing, and only the rod-shaped bracket 31 is described in cross section. The lifting mechanism 20 and the hook-shaped hook part 30 are raised or lowered by the crane chain, and the hook-shaped hook part 30 is accompanied by a movement that tilts left and right. The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting does not move.

  The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting from the ceiling is fixed, and is also fixed in FIG. The saddle type hook portion 30 is gradually raised from the lower side to the upper side by the crane when the inclined type conveyor is lifted. Therefore, when the hook-shaped hook portion 30 gradually rises and the head inclined portion 34 comes into contact with the rod-shaped bracket 31, it is pushed by the rod-shaped bracket 31 and gradually tilts to the right in FIG. ). In FIG. 3, the hook-shaped hook portion 30 is rotated and inclined at the hinge connecting portion with the lifting mechanism portion 20. However, the hook-shaped hook portion 30 may be gradually inclined with the lifting mechanism portion 20 as a shaft and a pivotable connecting portion with the inclined conveyor.

  The bar-shaped metal part 31 reaches the lowermost part of the head inclined part 34 of the hook-shaped hook part 30, and the hook-shaped hook part 31 is hooked on the bar-shaped metal part 31 of the hanging metal (FIG. 3C). The hook-type hook part 30 and the lifting mechanism part 20 which have been returned to the vertical state by the reaction pushed by the bar-like metal fittings as shown in FIG. At the same time, the lifting and fixing of the inclined conveyor is completed.

  Next, a mode in which the hook-shaped hook part of the hooking hook mechanism part is released from the state of being hooked on the ceiling hanging metal fitting will be described.

  FIG. 4 is a conceptual diagram showing a manner in which the hook-shaped hook portion of one example of the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to one embodiment of the present invention is released from the bar-shaped bracket. In the same manner as in FIG. 3, the hook-type hook portion 30 is laid on the upper side of the lifting mechanism portion 20 by a hinge mechanism that can be rotated and the hook-type hook portion is laid in a manner that can be rotated. The release plate 33 and the rod-shaped metal fitting 31 at the lower part of the ceiling hanging metal fitting are shown.

  FIG. 4 is an external view of the structure as seen from the side of the inclined conveyor as in FIG. This figure shows the movement from the drawing shown on the left side to the drawing shown on the right side in the order of the arrows until the hook-type hook part 30 and the lifting mechanism part 20 are released from the bar-shaped metal fitting 31. The ceiling hanging bracket 24 is omitted for easy understanding of the drawing, and only the rod-shaped bracket 31 is shown in cross section. The lifting mechanism 20 and the hook-shaped hook part 30 are raised or lowered by the crane chain, and the hook-shaped hook part 30 is accompanied by a movement that tilts left and right. The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting does not move.

  When the latch is released, the inclined conveyor, the lifting mechanism 20 and the hook 30 are once lifted upward by the crane. As a result, the rod-shaped metal fitting 31 that has been removed downward from the hook-shaped hook portion 30 apparently moves downward along the handle 35 of the hook-shaped hook portion 30 (FIG. 4, D to E). The rod-shaped metal fitting 31 hits the triangular plate-like release plate 33 laid on the handle 35 of the hook-shaped hook portion 30 and moves downward along the inclined surfaces (upper) 36 of the inclined portions on the two sides of the triangular plate (FIG. To f).

  The release plate 33 is fixed in a structure that is partially rotatable around a fixed axis with the handle 35 of the hook-shaped hook portion 30. As the saddle hook 30 and the lifting mechanism 20 are lifted by lifting the crane chain, the rod-shaped bracket 31 moves on the 36 slopes of the release plate 33 and reaches the slope (lower) 37 of the slopes on the two sides (FIG. 4). , From to chi). When the rod-shaped metal fitting 33 reaches the inclined surface (lower) 37 of the two-side inclined portion of the release plate, the lifting device chain gradually lowers the inclined type conveyor, the lifting mechanism portion 20 and the hook-type hook portion 30 downward. Start to take down. Then, the release plate 33 rotates, and the tip portion 38 where the inclined surface (upper) and the inclined surface (lower) of the two-side inclined portion intersects with the lower portion 39 of the hook of the hook-shaped hook portion 30 to stop the rotation of the release plate 33 ( FIG.

  Then, as the saddle type hook part 30 descends, the rod-shaped metal fitting 31 moves the head inclined part 34 of the saddle type hook part upward. As described above, the hook-shaped hook portion 30 is tilted to the right in FIG. 4 by the pressure of the rod-shaped bracket 31, and the rod-shaped bracket 31 is disengaged from the two side inclined portion tips 38 of the release plate 33. It will come off (Fig. 4, Ri to Nu). Thereafter, the entire inclined conveyor is gradually lowered downward by the lifting device and re-installed on the floor.

  The structure of the hook-type hook portion 30 of the lifting / lowering apparatus with an automatic attachment / detachment mechanism according to an embodiment of the present invention does not require any power when lifting and releasing the inclined conveyor, and the hook-type hook portion. The entire lifting mechanism 20 including 30 is connected and fixed to the inclined conveyor with a hinge structure that can be rotated in advance. Can move smoothly and tilt. Similarly, no power is required for this inclined movement.

  As a result, the heavy-duty inclined conveyor can be hooked automatically to the hanging brackets installed on the ceiling only by the lifting and lowering movement of the crane, so that it can be safely hooked and fixed so that it does not come off. When removing the hook, it is possible to automatically and safely release the latching hook only by the lifting and lowering movement of the lifting device. In the present invention, no power other than the crane lifting device is required for latching and releasing the hook portion and the hanging metal fitting. The pivotable hinge-type connection of the lifting mechanism to the inclined conveyor is not only the rotational movement of the connection angle with the lifting mechanism associated with the rising of the inclined conveyor, but also the hook-type hook to the hanging bracket The function of rotational movement can be doubled also in stopping and releasing.

  The lifting mechanism of the lifting and lowering apparatus with an automatic attachment / detachment mechanism according to an embodiment of the present invention includes a lifting mechanism section laid on an inclined conveyor, a coupling mechanism thereof, a ceiling hanging bracket, and a hook hook mechanism for a bar-shaped bracket. Ranges to automatic locking structure. However, the detailed shape, size, and material of the lifting mechanism section, hook section, release plate, ceiling hanging bracket, etc. are not limited to the contents of the above-mentioned one embodiment, and the functions described in detail are the invention's. It is the essence.

  Therefore, the same technique having the same function regardless of the detailed shape is included in the present application, and various modifications can be made without departing from the gist of the present invention. These are all part of this technical idea.

  As described above, according to the invention according to the present application, the inclined conveyor in the article transport conveyor line can be temporarily and easily removed to the ceiling surface at the merchandise collection and delivery base. Can be utilized for the purpose of. In addition, fixing the inclined conveyor for temporary removal of the ceiling is safe, and it is easy to install the inclined conveyor again.
