Abstract

A folding cage of a synthetic resin is dried after washing without the use of any hot air blower whereby reduction of a mechanical strength of the cage and thermal deformation of the cage are avoided. A folding cage (1) having been washed by a washing apparatus (400) is fed into a turn-over dewatering device (500). While the folding cage (1) is turned over by a conveying pawl (537), a template (539) abutting against the folding cage (1) from downward and inside brings the folding cage (1) into a vertical position to allow the same to fall shaking off a wash liquid therein, and pushes the folding cage (1) against a roller conveyor (513) on a turn-over outgoing side to cause the wash liquid on an outer surface of the folding cage (1) to be shaken off. Further, after the folding cages (1) are stacked by a stacking device (600), they are placed on respective stages (808) of a small-diameter turntable (802) of a centrifugal dehydrator (800), and are revolved by a centrifugal dehydrating station (804) at high speed to blow off the wash liquid due to centrifugal forces, so that the folding cages (1) are completely or substantially completely dried.

Description

 Description Folding basket washing and drying equipment

 The present invention relates to an apparatus for washing and drying a folding basket made of synthetic resin, which conveys articles such as vegetables and fruits or small parts. Background art

 Conventionally, when goods such as vegetables and fruits or small parts are transported by trucks or other freight vehicles, paper packing boxes such as cardboard boxes are used, and the goods are packed and packed inside. After the use of such articles, the paper packaging boxes such as the cardboard boxes were discarded. In recent years, such paper boxes have been collected and reused.However, such paper boxes are often soiled or broken during transportation, etc. Is still high and is extremely disadvantageous both economically and in terms of resource savings.

Therefore, it is becoming increasingly possible to use such transport containers made of synthetic resin such as plastic and to reliably reuse them. However, if such a synthetic resin transport container is transported in the shape of a container, that is, in the shape of a box or basket, even though the interior is empty, for example, at the location from which goods are taken out, unnecessary space becomes large. After all, waste is likely to occur in terms of the freight transport vehicles that transport them and the stocker yard where they are stored. Therefore, for example, such a synthetic resin transport container is formed in a basket shape without a lid, and when the inside is empty, both side walls are folded inward to form a thin plate shape. It is considered that there is no useless space when transporting to the unloading source. These foldable baskets made of synthetic resin will be simply These folding baskets, which are called baskets, include, for example, those manufactured by Ifco Japan Co., Ltd.

 Figure 39 shows the usage of this folding basket. In this folding basket 1, as shown in Fig. 39a, a rectangular bottom member 1a has a side wall corresponding to the short side thereof (hereinafter also referred to as a short side wall) 1b and a long side corresponding thereto. The side wall (hereinafter also referred to as the long side wall) 1 From the fully open state (hereinafter also referred to as the fully opened state) standing vertically or c, first, as shown in FIG. b is folded inward (hereinafter, this state, that is, the state in which only the long side wall 1 c is opened is also referred to as a half-open state), and then the long side wall 1 c is folded inward as shown in FIG. When it is knocked down (hereinafter, this state is also referred to as a closed state), the cage 1 is in a completely folded state. In the closed state or the folded state, if the sheet is conveyed to, for example, the conveyance source, no useless space is generated. When the cage 1 is used, the cage 1 in the fully opened state can be formed by opening the side walls in the order of the long side wall 1 c and the short side wall 1 b, contrary to the above. Incidentally, many slit-shaped gaps are formed in the bottom member 1a, the short side wall 1b, and the long side wall 1c of the folding basket 1.

However, even when the folding basket 1 made of such a synthetic resin transports articles such as vegetables and fruits as described above, both the inside and the outside of the basket are soiled. Naturally, the folding basket 1 contaminated in this way must be cleaned before reuse, but in the past, workers had to open these baskets one by one and manually clean the inside. However, this requires a lot of cleaning work, and the time required for cleaning is enormous. Therefore, the present applicant sets the folded basket in a closed state upside down, that is, when the bottom member 1a is placed one by one so as to be upward, and automatically puts it in a half-open state, and sprays the cleaning liquid from inside and outside. After washing off the attached dirt with the cleaning solution, the automatic cleaning device sends it out again in the closed state. Developed.

 However, since the automatic cleaning device merely cleans the folding basket, the cleaning liquid is likely to adhere to the folding basket sent from the cleaning device. For more efficient and clean storage of folding baskets, the washed folding baskets are completely dried, stacked on a transfer pallet by a specified number of layers, and the surrounding area is covered with synthetic resin wrapping material. Although it is desirable to pack it, the folding basket that has been sent from the washing device has a large amount of washing liquid attached to it, so it cannot be sent to the next step until it is dried. Yield decreases.

 The simplest way to dry such wet articles efficiently is to blow hot air, so-called blower drying. However, the temperature of the hot air at which the cleaning liquid, whose component is mostly water, is dried efficiently is 100 or more, whereas the synthetic resin folding basket is mechanically operated at a lower temperature. The blower drying cannot be used for drying the folding basket made of synthetic resin because the strength is reduced or the heat is deformed. Further, even if the temperature of the blown wind is set to a temperature at which the synthetic resin is not deformed or its mechanical strength is reduced, a thin slit is formed in the closed folding basket. In some cases, it is difficult for the wind to pass through to the inside of the folding basket in the closed state, and it is difficult for the wind to dry. Disclosure of the invention

The present invention has been developed in view of these problems, and efficiently and completely dries a folding basket sent out from the cleaning device without thermally deforming or reducing mechanical strength. Thus, the object of the present invention is to provide a folding basket washing and drying apparatus capable of improving the yield.

 Next, an embodiment of the folding basket cleaning and drying apparatus of the present invention will be described in detail with reference to the drawings.

In the folding basket washing and drying apparatus of the present embodiment, as shown in FIG. 1, two parallel lines A and B are formed up to the entrance side of the centrifugal dewatering apparatus due to the cycle time required for each treatment, Thereafter, processing is performed on a single line C. In this embodiment, first, the folding basket 1 stacked on the transfer pallet 2 is transferred by the traveling cart 100 to the loading device 200 provided at the loading entrance of the two lines A and B. In each loading device 200, only the stacked folding baskets 1 are loaded into the respective lines A and B as they are. Then, in the next cutting device 300, the stacked folding baskets 1 are cut out one by one (accurately one by one) and sent out, and the cleaning devices 4 are sent out by the conveyors 240, 241 and 242. 0 Feed into 0. In the cleaning device 400, the basket 1 folded in the opening step 410 described later is set to a half-open state, and the basket 1 is sprayed with cleaning liquid from various directions with various nozzles. The basket 1 is sent out again in the folded state by the closing step 4600. Next, the folded folding basket 1 is sent to an inverted drainer 500. In the reversing drainer 500, a slight impact is applied to the folded baskets 1 while the folded baskets 1 are flipped one by one twice to roughly drain the cleaning liquid adhering to the baskets. . And this roughly drained folding basket 1 積 After a predetermined number of stages are stacked by the lifting device, the line is integrated by the transfer device and sent to the centrifugal dehydrator. In this centrifugal dehydrator, the folding baskets stacked by the predetermined number of stages are rotated at high speed as they are to blow off the washing liquid by centrifugal force. The stacked folding baskets sent from the centrifugal dewatering device are placed in a predetermined stacking state on a transfer pallet by a carry-out device, sent to the next packaging device, and the pallet for transfer is performed by the packaging device. The wrapping band is wound around the entire folding basket placed in a stacked state on the top, wrapped, and transported by a forklift or the like.

Incidentally, in this embodiment, on the transfer pallet, for example, as shown in FIG. 6, three rows and two rows in plan view, and the bottom material 1 a shown in FIG. In other words, the folding baskets 1 are stacked one on top of the other on the short side wall 1b and the long side wall 1c. In each of the lines A and B, it is necessary to carry the folding basket 1 one row at a time for washing and drying. However, when the folding basket 1 has an area of the bottom material 1a that is half of that shown in a plan view, it is stacked on each transfer pallet in three columns and four rows. Each row A and B must be loaded with one row of folding baskets. The schematic structure of the folding basket 1 to be washed and dried is the same as the conventional one described above, but the shape is not the simple one as described above, but has a complicated shape such as a bump and a depression. ing. However, here, in order to facilitate understanding, only those necessary parts will be described in the description part of each device. Next, before describing the traveling trolley, two rails 11 are laid on the entry side of each of the lines A and B in a direction orthogonal to the lines A and B, and a rack rail 12 between them. Are also laid. A traveling vehicle 100 is mounted on these rails 11 and rack rails 12. This traveling vehicle 100 has a rectangular frame as shown in FIGS. It is mounted on the two rails 11 via four rotatable wheels 102 mounted on the lower surface of 101. An electric motor 103 is mounted on the upper portion of the frame 101, and a sprocket 105 mounted on the rotating shaft 104 of the electric motor 103 and the frame 1 A chain 109 is wound between the spun UJ-ket 108 of the rotating shaft 107, which is rotatably mounted via a bearing 106, at the lower part of 01, and the rotating shaft 1 A pinion 110 that fits with the rack rail 12 is attached to 07 by a positioning mechanism 111 such as a key. Therefore, when the electric motor 103 is rotated in a predetermined direction, the rotational force is transmitted in the order of the sprocket 105, the chain 109, the sprocket 108, and the rotating shaft 107. As a result, the pinion 110 is rotated while being engaged with the rack rail 12 so that the entire traveling vehicle 100 including the frame 101 is moved in the direction of the arrow a shown in FIG. 3 or FIG. You. Of course, if the electric motor 103 is rotated in the opposite direction to the above, it is possible to cause the traveling carriage 100 to travel in the opposite direction to the arrow a. Incidentally, reference numeral 112 in the figure denotes a tension adjusting mechanism for adjusting the tension of the chain 109 by moving the electric motor 103.

The upper surface of the frame 101 has two wall-shaped support members 121 with notches formed at two locations facing each other. The force is orthogonal to the two rails 11. Are erected in parallel to each other in the direction. A plurality of rollers 122, 123 whose upper surfaces are at the same horizontal plane are rotatably suspended between the upper portions of the two support members 121. Of these, reference numeral 122 denotes a driving roller which is driven to rotate by an electric motor 124, and reference numeral 123 denotes a so-called free roller which does not receive a driving force. As a result, the upper surfaces of the rollers 122 and 123 move as a whole in the direction of arrow b with respect to the floor surface. These rollers 122, 123 are illustrated in FIG. The transfer pallet 2 on which the folding baskets 1 are stacked is automatically transported from a stocker (storage device) onto the traveling carriage 100. The transfer pallet 2 on which the folding baskets 1 are stacked is usually placed on the upper surfaces of these rollers 122, 123 as shown in FIG.

 On the upper side of the frame 101, a horizontal member 13 1 is provided at each of the two cutout portions of the support member 121 in a direction orthogonal to the support member 121. These are arranged, and these are connected by vertical members 13 2 arranged at appropriate intervals to form a movable frame 133. In addition, the movable base 133 is connected to the frame 101 via an air cylinder 134 and a guide device 135. In addition, on each of the horizontal members 13 1 of the movable gantry 13 3, the traveling carriage 100 is provided via spout packets 13 36 provided at both ends of the horizontal member 13 1. The chain conveyor 13 7 is arranged in the moving direction, that is, in the same direction as the direction of the arrow a in FIG. Then, the sprockets 13 36 located at the right end in FIG. 4 are connected to each other by a rotating shaft 1338, and a separate sprocket 13 9 is attached to the rotating shaft 13, and this sprocket 13 Reference numeral 9 denotes a sprocket 14 3 provided on the rotary shaft 14 2 of the electric motor 14 1 on the support frame 14 provided integrally below the moving frame 13 3, and a chain 14 4 Connected by four. Incidentally, the electric motor 14 1 is composed of a servomotor such as a pulse motor, and its rotation speed and the like can be adjusted and controlled.

Therefore, the traveling cart 100 is moved from a stocker (not shown) to the transfer pallet 2 on which the folding basket 1 is stacked by the mouths 122, 123 by the rollers 122, 122. After the transfer, the pinion 110 is rotated by rotating the electric motor 103 and moved to a predetermined position of each carry-in device 200. Stretched Then, the chain conveyor 13 7 is moved up to the position indicated by the phantom line in FIG. Thus, the transfer pallet 2 on which the folding baskets 1 are stacked is also raised to the position indicated by the imaginary line. Then, in this state, the stacking folding baskets 1 are loaded into the line A or the line B by the loading device 200 described later by one row, and when the loading of the folding baskets 1 in the row is completed, By rotating the electric motor 14 1, the chain conveyor 13 7 is moved in the direction of arrow c by one row of the stacked folding baskets 1, and stacked on the transfer pallet 2. The folding basket 1 in the next row is moved to a predetermined position on the entry side of the loading device 200, and is loaded in the same manner as described above. Then, the folding basket 1 in the next row is moved and loaded. Then, when all the folding baskets 1 on the transport pallet 2 have been carried in, the air cylinder 13 34 is contracted to lower the chain conveyor 13 7 and the movable pedestal 13 3. As shown in the figure, only the transfer pallet 2 is again mounted on the mouths 122, 123, and then the carriage 100 is moved in the direction of arrow d in FIG. The pallet 2 is transferred to a pallet stocker by a transfer device (not shown) or a forklift.

Next, the loading device 200 will be described in detail with reference to FIGS. As shown in FIG. 5, for example, as shown in FIG. 5, the loading device 200 is composed of a portal frame 201 so as to straddle the rail 11 and the rack rails 12 and the traveling vehicle 100 mounted thereon. In rare cases, a portal frame 202 for providing a cutting device 300 described later also extends to the left in FIG. 5, that is, in the transport direction of the lines A and B. These portal frames 201 and 202 have at least a height equal to or higher than the height of the stacked folding baskets 1, and are stacked on both sides of the transfer lines A and B. Guide plates 203 for guiding the side surfaces of the folding basket 1 are attached at predetermined intervals as shown in FIGS. In addition, of the portal frames 201 and 202, the lower surface of the intermediate beam member 211 disposed above the rail 11 for the traveling carriage 100 has a line transfer line. Guide plates 2 1 2 are attached along the direction. Further, two guide rails 214 are laid on the upper surface of the uppermost beam member 21 3 of the portal frame 201 along the line transport direction. A movable frame 2 16 is mounted on these guide rails 2 14 via a linear guide 2 15. A support plate 2 17 extends from the movable gantry 2 16 downwardly below the lower surface of the beam member 211 at the center toward the transfer line side. Guide rollers 2 18 are attached to the lower end of 17 so as to sandwich both sides of the guide plate 2 12. In addition, the beam members 2 13 below the movable gantry 2 16 and at the top of the portal frame 201 are racked along the guide rails 2 14 so that the teeth are directed sideways.

The tip of the piston port 238 of the cylinder 237 is rotatably connected. Therefore, when the piston rod 238 of the air cylinder 237 is expanded and contracted, the rotating shaft 233 is rotated through the rotating arm 236, thereby the push plate 233 mounted on the mounting arm 234. 5 reciprocates from the two-dot chain line to the solid line position as shown. As described above, in the carrying-in device 200, the folding cart 1 stacked on the transport pallet 2 by the traveling carriage 100 is moved to the position indicated by the two-dot chain line in FIG. 6, for example. The piston port 238 of the stretched air cylinder 237 is contracted from the position indicated by the two-dot chain line to the position indicated by the solid line in FIG. 6 to rotate the rotating shaft 233. As a result, the push plate 2 35 attached to the attachment arm 2 3 4 is rotated from the position indicated by the two-dot chain line a to the position indicated by the solid line in the drawing, and Make them face each other. In this state, when the electric motor 220 is rotated in a predetermined direction, the pinion 219 rotates while being engaged with the rack rail 218. The push plate 235 is moved in the direction of arrow d in FIG. 6 together with the push plate 235, and the push plate 235 pushes out the stacked single row of folding baskets 1 in the direction of arrow d shown in FIG. When the rack moves from the position indicated by the solid line in the figure to the position indicated by the two-dot chain line b, the folding basket 1 in the single row moves from the transfer pallet 2 to the above-mentioned cutting device 30 above the belt conveyor 240. It is transferred to 0, which completes the loading of the folding basket 1 for the one row. At this time, the side walls of the stacked single row folding baskets 1 are guided by the guide plates 203 during the transfer. When the loading of the one row of folding baskets 1 stacked on the transfer pallet 2 in this manner is completed, the electric motor Rotate 220 in the opposite direction to the above and return the push plate 2 35 together with the moving platform 2 16 to the position indicated by the solid line in the figure, and then, as described above, the chain conveyor 1 3 7 of the traveling vehicle 100.

Next, the cutting device 300 will be described in detail with reference to FIGS. The cutting device 300 includes a lowering device 310 that lowers the lowermost folding basket 1 of the stacked folding baskets 1 and places it on a belt conveyor 240, and And a support device 350 for supporting the folding basket 1. Among them, the lowering device 310 is provided with two guide rails 311 mounted vertically on each of both sides of the frame 301 supporting the belt conveyor 240, and A movable base 3 13 arranged slidably in the vertical direction via a linear guide 3 1 2 with respect to the guide rail 3 1 1, and the movable base 3 13 includes the belt conveyor 2. The piston rod 3 15 of the air cylinder 3 14 fixed to the frame 30 of 40 is connected, and the movable base 3 13 is placed above the belt conveyor 240, respectively. An air cylinder 317 with a piston rod 316 extending and contracting is attached to the inside and outside of the belt conveyor 240. A support member 318 for supporting the lower surface of the lowermost folding basket 1 is attached to the distal end of the biston rod 316 of the air cylinder 317 on the movable base 313. Of the members 3 18, guide bars 3 19 are provided on both sides of the air cylinder 3 17 so as to project toward the movable base 3 13, and the guide bars 3 19 are mounted on the movable base 3. It is connected to a guide device 320 provided in 13. Therefore, for example, when the piston rod 1336 of the air cylinder (hereinafter also referred to as a supporting air cylinder) 317 on the moving base 313 expands and contracts, the support member 318 becomes The piston of the air cylinder (hereinafter also referred to as a descending air cylinder) attached to the frame 301 is reciprocated between the position indicated by the solid line in FIG. 10 and the position indicated by the two-dot chain line a. When the rod 3 15 is expanded and contracted, the support member 3 18 is reciprocated along with the movable base 3 13 between the position indicated by the solid line and the position indicated by the alternate long and two short dashes line b in FIG.

 In addition, the supporting device 350 is provided with a frame 301 supporting the belt conveyor 240, and a gate-shaped frame 351 erected around the lowering device 310. In this portal frame 351, above the supporting air cylinder 317 of the lowering device 310, a piston rod 352 is also provided with a belt conveyor 240. An air cylinder 3 5 3 that expands and contracts outward is installed. The lower end of the piston rod 3 52 of the air cylinder 35 3 supports the lower surface of the protrusion 1 d formed on the side surface of the upper folding basket 1 above the lowermost folding basket 1. The upper basket support member 35 54 is attached, and guide bars 35 5 on both sides of the upper cylinder support member 35 4 sandwiching the air cylinder 35 3 are directed toward the portal frame 35 1. The guide bar 355 is connected to a guide device 355 provided on the portal frame 351. Accordingly, when the piston rod 352 of the air cylinder of the support device 350 (hereinafter also referred to as an air cylinder for supporting the upper basket) 353 expands and contracts, the upper basket support member 354 becomes the lowermost cylinder. The direction of arrow e-f in Fig. 10 is such that the upper side of folding basket 1 approaches folding basket 1 (hereinafter also referred to as the second lower folding basket 1) and moves away from it. Is reciprocated.

As described above, in the cutting device 300, first, the piston rod 35 2 of the upper cylinder support air cylinder 35 3 of the support device 350 is contracted, and the upper basket support member 35 4 is folded. 1 and the piston rod of the lowering air cylinder 314 of the lowering device 310 is extended. The movable gantry 3 13 is raised, and the piston rod 3 16 of the support air cylinder 3 17 is extended, and the lowermost folding basket 1 on which the support members 3 18 are stacked is stacked. In a state opposite to the lower surface, that is, in a state shown by a solid line in FIG. 10, the carrying-in device 200 puts a step on the supporting member 318 of the descending device 310 as shown by a two-dot chain line in FIG. The stacked folding basket 1 is loaded.

Next, the piston rod 352 of the upper cylinder support air cylinder 353 of the support device 350 is extended, and the upper cage support member 354 is moved to the second lower folding basket 1 from the bottom. The upper basket supporting member 354 is brought closer to the side surface so that the upper surface of the upper basket support member 354 faces the lower surface of the projection 1 d on the side surface of the second folding basket 1 from the bottom. From this state, when the biston rod 3 15 of the descending air cylinder 3 14 is contracted and the support member 3 18 is lowered in the direction of arrow g in FIG. 10, the lowermost fold supported by the lower member is supported. As basket 1 descends, folding basket 1 above it also attempts to descend. However, since the protrusion 1 d on the side surface of the second folding basket 1 from the bottom is supported by the upper basket supporting member 3554, the lowering of the folding basket 1 in the upper stage is restricted and the state is maintained. Will be maintained. Therefore, when the support member 3 18 is lowered to the position indicated by the two-dot chain line in FIG. 10, the contraction of the piston rod 3 15 of the lowering air cylinder 3 14 is stopped. The piston rod is contracted, and the support member 318 is simultaneously moved in the direction of arrow h in FIG. Then, the lowermost folding basket 1 supported by the support member 3 18 is no longer supported from below by the support member 3 18, and falls slightly onto the belt conveyor 240. Is placed. When the series of cutting steps is completed, the belt conveyor 240 is driven to rotate, and the lowermost folding basket 1 placed on the belt conveyor 240 is transferred. At the same time, the piston of the lowering air cylinder 3 1 4 The rod 3 15 is extended to raise the supporting air cylinder 3 17 together with the moving base 3 13 in the direction of the arrow i in FIG. 10. Then, when the support member 3 18 force is raised to the position indicated by the two-dot chain line in FIG. 10, the piston rod 3 16 of the support bearing cylinder 3 17 is extended, and the support member 3 18 Move in the direction of arrow j in the figure to the position indicated by the solid line in the figure. In this state, when the piston α 352 of the upper cylinder support air cylinder 35 3 of the support device 350 is contracted, the folding basket 1 of the second stage from the bottom supported by it is However, the lowering device 310 slightly drops to above the support member 318, and accordingly, the folding basket 1 in the upper stage also lowers. Therefore, the folding basket 1 that has dropped onto the supporting member 3 18 of the descending device 3 10 becomes the new lowest folding basket 1, and the folding basket 1 above it is the second folding basket 1 from the bottom. Therefore, the operation after the above-described loading is repeated, and the stacked folding baskets 1 are cut out one by one from the bottom to the belt conveyor 240, and are transported along the line Α or the line Β. Can be. The folding basket 1 cut out one by one on the belt conveyor 240 in this way is carried over to the following two belt conveyors 241 and 242 and sent to the cleaning device 400.

In addition, the tip of the jetting pipe material 43 1 along the transfer direction of the folding basket 1 is closed, and the long side wall 1 c of the jetting pipe material 43 1 Many small holes 4 3 3 are drilled. Therefore, by the so-called crank motion of the electric motor 4 34 shown in FIG. 11, the connecting pipe member 4 32 is swung in the vertical direction, that is, in the direction of the arrow 0-0 in FIG. When the cleaning liquid under pressure is supplied from the connecting pipe material 432 to the jetting pipe material 431, the small holes 433 of the jetting pipes 431, etc. The cleaning liquid is sprayed upward and downward toward the long side wall 1 c of the folding basket 1 in the state.

In the next third washing step 440, as shown in Fig. 14c, the supply pipe member 441, which also serves as a rotating shaft, is located above the bottom member 1a of the folding basket 1 to be transferred. The distribution chambers 442 are provided at the lower end thereof, and connecting pipe members 443 are protruded from the four sides thereof, and the chambers are provided at the ends of the connecting pipe members 443. 444 are provided, and a jet nozzle 445 is provided on the lower surface of each chamber 444. Therefore, the motor shown in Fig. 11 While rotating the supply pipe member 441 serving also as the rotary shaft in the direction of the arrow p in FIG. 14C by the motor 446, the distribution pipe 441 from the supply pipe 441 to the connection chamber is connected. When the cleaning liquid lacking pressure is supplied in the order of the pipe member 4 4 3 and the chamber 4 4 4, the cleaning liquid is rotated from the nozzles 4 4 5 toward the bottom member 1 a of the folding basket 1 while rotating. It is gushing. In the next finish cleaning step 450, as shown in Fig. 14d, chambers 451 are provided above and below the folding basket 1 to be transported, and each chamber 451 has a nozzle that jets the cleaning liquid widely. 4 5 2 are provided. Therefore, when the cleaning liquid under pressure is supplied to each of the chambers 451, the cleaning liquid is widely ejected from the nozzles 452 from above and below the bottom material 1a of the folding basket 1 to be transferred. Is done.

 In this way, the folding basket 1 from which all attached unnecessary materials have been washed is transferred to the closing step 460 shown in FIG. In this closing step 460, as shown in FIG. 15, the entrance side of the folding basket 1 in the transfer direction is wider than the opened long side wall 1c and the center of the long side wall 1c or higher. A guide bar 4 61 is disposed downward, and is smoothly curved so as to come into contact with the lower surface of the closed long side wall 1 c on the exit side in the transport direction of the folding basket 1.

On the other hand, a template 539 as shown in FIG. 19 is provided inside each of the two opposite transporting claws 537 of the reversing device 530. . These templates 539 are fixed to the upper part of the frame 501, and the outer shape is the rotation direction of the rotation shaft 534 from the entrance side of the folding basket 1 in the transfer direction, that is, FIG. An arc-shaped outer peripheral surface 539a with a large radius of curvature is formed up to a position that is vertical or almost vertical in the directions of arrows r and u, and then has a larger radius of curvature until the exit side of the folding basket 1 in the transfer direction. It is formed on a small arc-shaped outer peripheral surface 539b, and is formed of a vertical surface 539c at a connection point between the two, that is, at a position which is vertical or almost vertical in the rotation direction of the rotary shaft 534.

In addition, the folding basket 1 is hit against the belt conveyor 5 13 or 5 14 on the exit side in the transfer direction of the folding basket 1 with respect to the rotation direction of the rotating shaft 5 3 4 and the conveying claw 5 3 7. As the driving device, a transport claw locking Z drop device 540 as shown in FIG. 17 is provided. The transport claw locking Z dropping device 540 includes an air cylinder 541, which is disposed upward from both upper beam members 501a of the frame 501, and a frame 501, similarly.

Therefore, this inverted drainer 500 operates as follows. However, here, only one operation of the four transport claws 537 protruding from the rotary shaft at every 90 ° will be described in detail, and the other transport claws have a rotary shaft of 9 °. 0. Since it operates in the same way when rotated, a detailed description thereof will be omitted. That is, the folding basket 1 sent from the belt conveyor 480 is transported in the direction of the arrow q by the belt conveyor 512 on the entry side, and the belt on the entry side of the reversing device 5300 is soon. The sheet is fed between the openings of one of the transport claws 537 waiting to face the conveyor 512 and comes into contact with the template 539. When the folding basket 1 comes into contact with the template 539 in this way, the rotation axis of the reversing device 5330 is rotated in the direction of arrow r (u) in FIG. 19, and accordingly, both ends in the width direction of the folding basket 1 The transport claws 537 supported so as to sandwich the portion are rotated in the same direction. Thereafter, when the rotating shaft 5 3 4 and the conveying claw 5 3 7 of the reversing device 5 30 are in the vertical or almost vertical position in the rotational direction thereof, the folding is performed. With the upper end of the basket 1 in contact with the contact plate 547, as shown in Fig. 19, the folding basket 1 is held from below by the outer peripheral surface 539a having the same radius of curvature until then. The template 5 3 9 that was supported The folding basket 1 is supported from below by the outer peripheral surface 539 b with a small radius of curvature through the vertical plane 5 39 c. The template 539 falls in the direction of the arrow s (v) to the outer peripheral surface 539b having a small radius of curvature, and the washing liquid attached to the folding basket 1 is shaken off by a slight impact at that time. In particular, at this time, the cleaning liquid adhering to the inside of the folded folding basket, that is, the surface where the bottom member 1a, the short side wall 1b, and the long side wall 1c are closed, flows along them. Is effectively shaken off to the outside.

Even when the folding basket 1 falls in this way, the folding basket 1 continues to be further rotated in the direction of the arrow r (u) while being sandwiched by the transport claws 537 on both sides in the width direction. Incidentally, even if the contact plate 545 is pressed against the folding basket 1 in the rotation direction of the folding basket 1 while being in contact with the folding basket 接触, the contact with the upper end of the folding basket 1 is caused. When there is no more, it is dropped down by the tension panel 548. Also, at this time, the piston rod 542 of the air cylinder 541 of the transport claw locking / falling device 540 is extended, and the locking Z drop claw 5444 is shown by a two-dot chain line in FIG. As shown in the figure, if the U-shaped upper end portion 544 a is positioned inside the transport line, the plate 5 3 for locking the transport claw 5 3 7 which continues to be rotated. 8 comes into contact with the roller 545 of the upper end 5 4 4a of the locking / dropping claw 5 4 4 and cannot be moved further in the rotation direction. The hammo that drives 3 4 in rotation also stops 5 3 1. However, since this air humor 531 allows a slight phase difference within the allowable range of the compression deformation of the supplied air, that is, within the allowable range of the air pressure for driving the air humor 531, Locking the transport claw within the range Z Air dropper 540 Air cylinder 54 1 Piston When the connecting rod 542 is contracted, the locking Z drop claw 544 rotates around the support point of the bracket 543, and as shown by a solid line in FIG. The lower end 5544 b moves inside the transfer line, and the upper end 5544 a comes off the locking plate 538 force of the transfer claw 537. The transport claw 537, whose movement in the rotation direction has been restricted until then, rapidly rotates in the downward direction by the air pressure compressed in the air motor 531. Then, the folding basket 1 sandwiched by the transport claws 5 3 7 is hit on the belt conveyor 5 13 in the next central portion, and here, due to the slight impact, adheres to the folding basket 1. Cleaning solution is shaken off. At this time, the cleaning liquid adhering particularly to the surface hit against the belt conveyor 5 13 is effectively shaken off.

 At this time, the transport claw locking and dropping device 540 locking Z dropping claw 544 lower U-shaped lower end portion 544 b is a locking plate for the transport claw 537 locking plate. The transport claw 5 3 Ί is positioned below 5 3 8 so that it does not rotate below it. Then, again extend the biston rod 542 of the air cylinder 541 of the dropping device 540 with the carrier claw locking and dropping device 540, and make the U-shaped lower end 5 44b is removed from the outside of the transfer line to enable rotation of the transfer claw 537, and the upper end portion 5444a of the transfer claw 537 is provided inside the transfer line with the next transfer claw 537. Move it. At this time, the folding basket 1 is inverted so that the bottom member 1a faces downward, contrary to the previous transport.

On the other hand, the folding basket 1 hit on the central belt conveyor 513 is transferred as it is in the direction of the arrow t by the central belt conveyor 513, and sent to the next reversing device 5330. In this reversing device 530, similarly to the above-described reversing device, while the folding cage 1 is reversed by the transport claw 537, the balance basket 1 is temporarily moved to a position where it is vertical or almost vertical. When the folding basket 1 falls along the rate 5 39, the cleaning liquid still attached to the folding basket 1 is shaken off, and the folding basket 1 is driven into the next belt conveyor 5 14 on the outlet side. The washing liquid still attached to the folding basket 1 is shaken off. In this way, the folding basket 1 that has been inverted twice has the bottom member 1a facing upward, as in the case where the folding basket 1 is sent to the entry side. Therefore, the pushing device 550 stretches the folding basket 1 sent out from the belt conveyor 514 on the outlet side by extending the piston cod 552 of the air cylinder 551 to the next stacking. It is fed in the direction of arrow w into the belt conveyor 65 0 on the input side of the device 600.

Next, the stacking device 600 will be described in detail with reference to FIGS. The stacking device 600 is provided with a belt conveyor 650 for transferring the folding basket 1 sent out from the inverted water draining device 500 on its entry side. This belt conveyor 65 is slightly different from the conventional belt conveyor, and for example, as shown in FIG. 22, is separated by a predetermined distance in a direction orthogonal to the transport direction, that is, in the width direction of the folding basket 1. It has a book belt 651. Each of the belts 651 includes a pulley 652 disposed at a position where the folding basket 1 is extruded from the pushing device 550 of the reversing drainer 500, and a stacking device 600. Of the two pulleys corresponding to each belt 651, which are wound between the pulleys 653 arranged in the lower central part, the pulley 652 at the position where the folding basket 1 is pushed out. Each of them is attached to one rotating support shaft 655 via a bearing 6554, and the pulleys 653 arranged at the lower central portion of the stacking device 600 main body, respectively. It is attached to one rotating shaft 657 via a positioning mechanism 656 such as a key. A sprocket 658 is attached to the rotating shaft 657. The sprocket 658 and the electric motor 659 provided on the lower entry side of the stacking device 600 are rotated. Switch attached to axis 660 The chain 662 is wound between the bracket 661 and the bracket 661. Therefore, when this electric motor 659 is rotated in a predetermined direction, the two belts 651 are rotated in synchronization, whereby the folding basket 1 is moved from the position pushed out by the pushing device 5550. It is transported to the center of the stacking device 600. Incidentally, reference numeral 663 is a tension adjusting mechanism of the chain 662, and reference numeral 664 is a tension adjusting mechanism of the belt 651.

Sprockets 6 are provided between the two belts 651 of the belt conveyor 650 and on the entrance side and the exit side in the transfer direction sandwiching the pulley 653 at the center of the stacking device 600. 0 1 and 6 0 2 are provided. Of these, the sprockets 601, on the entering side of the folding basket 1 in the transfer direction, are provided with a rotation support shaft 606 between brackets 605 projecting from the frame 604. It is rotatably supported with respect to 606 via a bearing 607. On the other hand, the sprockets 602 on the exit side in the transport direction of the folding basket 1 are directly connected to the rotating shaft 609 rotatably supported on the frame 604 via the bearing 608, and a key or the like. It is mounted via a positioning mechanism 6 10. Then, a chain 603 is wound between these sprockets 61 and 62, and furthermore, the chain 603 has a position where the chain 603 makes a half turn, or a position where the chain 633 faces each other, that is, For example, in FIG. 20, a push plate 611 is attached to a portion corresponding to the position of the outgoing sprocket 602 with respect to the position of the incoming sprocket 601. Incidentally, the upper surface of the layout of the chain 603 is lower than the upper surface of the belt conveyor 650, but the upper surface of the trajectory of the push plate 611 is the lower surface of the belt conveyor 650. It is located above the upper surface. An individual sprocket 612 is attached to the rotating shaft 609, and the sprocket 612 and the stacking device 609 are mounted. A chain 616 is wound around a sprocket 615 mounted on a rotating shaft 614 of an electric motor 613 provided on a lower exit side of the main body. Therefore, when the electric motor 613 is rotated in a predetermined direction while the belt conveyor 650 is stopped, the chain 603 is rotated with this rotation. A push plate 611 attached to the chain 603 is brought into contact with the folding basket 1 stacked on the exit side of the belt conveyor 65 by the stacking device 600, and is moved in the transport direction. It can be transferred and sent out onto a chain conveyor 680 described later. Incidentally, reference numeral 6 17 denotes a tension adjusting mechanism of the chain 6 16 between the electric motor 6 13 and the rotating shaft 6 09, and reference numeral 6 18 denotes the two sp □ kets 6 0 1, 6 0. O A tension adjustment mechanism for the chain between the two

 On the other hand, on both sides of the chain 603 and the belt 651 in the transport direction, elevating devices 620 constituting the main body of the stacking device 600 are provided. The lifting / lowering device 620 includes an air cylinder 621, which is disposed upward on both sides of the frame 604, and a moving device attached to the tip of a piston rod 622 of the air cylinder 621. The gantry includes a gantry 623, a guide bar 264 projecting downward from the movable gantry 623, and a guide device 625 through which the guide bar 624 is inserted. In addition, on the movable gantry 6 23, elevating claws 6 2 6 for supporting the folding basket 1 from below and moving up and down are provided on the entrance side and the exit side of the folding basket 1 in the transfer direction and at the center thereof. It is mounted on a rotating base. By the way, of the guide plate 627 protruding upward from the frame 604 to guide both side surfaces of the folding basket 1 to be transferred, a portion to which these lifting claws 626 correspond, The lifting claw 6 26 is cut out so as not to hinder the lifting.

These lifting pawls 6 2 6 are, for example, as shown in FIG. Mounted on 2 3 That is, bearings 628 with their axes directed in the transport direction are erected on the movable gantry 6 23 at portions corresponding to the lifting claws 6 26, and these bearings 6 2 8 are attached to the rotating shaft 6. 2 9 are communicated. The outer cylindrical portion 626a of the lifting claw is fixed to the rotating shaft 629 by a set screw 6330. Therefore, the lifting claw 6 26 rotates from the fixed position shown by the solid line in FIG. 24 to the flip-up position shown by the two-dot chain line in FIG. The inner upper end surface 6 26 b of the lifting claw 6 26 is formed horizontally at a fixed position shown by a solid line in FIG. 24, and similarly, the lower portion on the inner side has a tapered surface 6 whose lower portion extends outward in the transport direction. 26C is formed. A bracket 631 projects downward from the moving base 623, a coil spring locking shaft 632 projects from the bracket 631, and a taper of the elevating pawl 626. At the lower end of the surface 6 26 c, that is, at the lower part on the tip side of the elevating claw 6 26, a coil spring locking shaft 6 33 is protruded, and both locking shafts 6 3 2, 6

Both ends of the coil spring 6 3 4 are locked to 33. Further, on the moving stand 6 23, further on the exit side of the elevating claw 6 2 6 on the exit side, a stopper 6 35 for regulating the folding basket 1 to be transferred is attached. Incidentally, the lifting claw 6 2 6 in the central portion is the half of the bottom member 1 a of the folding basket 1, which is half of the planar view illustration, that is, the folding basket whose length in the transport direction is half. Also in 1, the lifting claw 6 26 in the center and the lifting claw 6 26 on the exit side are provided at positions where the lower surface of the folding basket 1 having the half length can be supported. Reference numeral 636 shown in each figure is a support plate that supports the folding basket 1 in a stacked state, which is raised and lowered by the lifting claw 626 from below.

Therefore, once the folding basket is moved by the belt conveyor to a position where it comes into contact with the stopper 635 of the movable base 623, the piston rod 622 of the air cylinder 621 of the lifting device 620 is extended. And mobile rack Raise the platform 6 2 3. As a result, the inner upper end surface 6 26 a of the lifting claw 6 26 that had been located below the folding basket 1 abuts on the lower surface of the transferred folding basket 1 and is raised as it is. When the folding basket 1 transferred earlier in this way is lifted and the front part of the stopper 635 is vacated, the next folding basket 1 is brought to a position where it comes into contact with the stopper 635 in the same manner as described above. Transfer. In this state, when the piston port 6 22 of the air cylinder 6 2 1 is contracted to lower the lifting claw 6 2 6 raised as described above, The taper surface 6 2 6c force, abutting against the side surface from the top surface of the folding basket 1 stopped in contact with the stopper 6 35, for example, as shown by the two-dot chain line a in FIG. The folding basket 1 supported by the lifting claw 6 2 6 is now strong, and is placed above the folding basket 1 that has stopped in contact with the stopper 6 35. Is done. Then, from this state, when the piston rod 622 of the air cylinder 621 is further contracted to lower the elevating pawl 626, its inner end comes into contact with the stopper 635 and stops. The lifting claw 6 26 is released from the side surface of the folding basket 1, and is restored to the fixed position indicated by a two-dot chain line b in FIG. 23 by the elastic force of the coil spring 6 34. Then, the piston rod of the air cylinder 6 21 is moved from a state in which the inner upper end surface 6 2 6 a of the lifting claw 6 2 6 is located below the folding basket 1 stopped in contact with the stopper 6 35. When 6 2 2 is extended, the folding baskets 1 stacked in two stages are supported by the inner upper end surface 6 2 6 a of the lifting claw 6 2 6 from above and ascend. By repeating this, when a predetermined number of folding baskets 1 (10 in the figure) are stacked above the raising and lowering claws 6 26, the stopper 6 35 is moved together with the moving base 6 2 3 into the chain 6 2 Then, they are lowered and replaced on the support plate 6336, and in this state, the electric motor 613 is rotated to rotate the chain 63. Then, it is attached to the relevant chain The push plate 611, which is in contact with the folding baskets 1, is pushed from the rear of the stacked folding cages 1, pushed out in the transport direction, and sent out to the next chain conveyor 680.

 Next, the chain conveyor 680 will be described in detail with reference to FIGS. 25 and 26. FIG. Two chain conveyors 680 are provided in series for each of the transport lines, and each of the chain conveyors 680 is provided on the outlet side and the inlet side of a separate frame 681 respectively. The sprockets 684 are mounted parallel to the rotating shaft 683 rotatably mounted via bearings 682, and the opposite sprockets 684 and the column members 6 in the center of each frame 681 The chain 687 is wound between the sprockets 686 which also serve as the tension adjusting mechanism provided in the 885. In addition, a separate sprocket 688 is attached to the rotating shaft 683 on the outlet side of each chain conveyor 680, and the sprocket 688 is provided on the lower outlet side of each frame 681. A chain 692 is wound between the electric motor 689 and the sprocket 691 connected to the rotating shaft. Incidentally, the electric motor 689 is constituted by a servomotor such as a pulse motor. In addition, a washing liquid receiving stand 693 having a water gradient for receiving the washing liquid falling from the folding basket 1 is provided below each frame 681.

Therefore, when the electric motor 689 of each chain conveyor 680 is rotated in a predetermined direction, the chains 687 are respectively rotated in a predetermined direction, and accordingly, the chains 687 are fed from the stacking device 600. The folded basket 1 in the stacked state is transferred by two chain conveyors 680 in the direction of arrow a ′ in FIG. Incidentally, on the two chain conveyors 680, the stacked folding baskets 1 can be placed in a state where only a predetermined maximum number of sets (up to eight sets in the figure) can be placed. Depending on the fluctuation of the operation rate between the process up to the stacking device 600 and the process after the transfer device 700 described later, The chain conveyor 680 has a function as a slight stocker. However, if the cycle time of both is the set time, in order to improve the yield as much as possible, these chain compensators 680 always have a maximum number of folding baskets 1 should be placed, and it should flow sequentially from the preceding process to the subsequent process. Therefore, the position sent from the stacking device 600 located at the rightmost position in FIG. 25 is transferred to a first station, a transfer device 700 described later located at the leftmost position in FIG. When the position is set to the eighth station, and the positions obtained by dividing them into seven equal parts are set to the second to seventh stations, respectively, the electric motor 689 consisting of the above-mentioned servo-boom is used for every predetermined cycle time. By rotating the folding baskets 1 in a stacking state waiting at each station to the next station by rotating them by an amount corresponding to the pitch of each station at a time, that is, sending them to the subsequent transfer device, We try to improve the yield.

 Next, the transfer device 700 will be described in detail with reference to FIGS. 27 to 29. The transfer device 700 is opposed to the two transport lines A and B, with a delivery line to a centrifugal dehydrator 800 to be described later being inserted into a centrifugal dehydrator 800 to be described later.

A movable base Ί 05 is attached, and a guide bar 706 protruding downward from the movable base 705 is inserted into the guide device 704. The free port is mounted rotatably so as not to interfere with each of the chains 687 of the outlet side chain conveyor 680. Therefore, in a state where the piston rod 703 of the air cylinder 702 is contracted, the upper surface formed by the rollers 707 on the moving base 705 is formed by the chain 6 of the outlet-side chain conveyor 680. When the piston rod 703 of the air cylinder 702 is extended, the moving base 705 and each roller 707 pass between the chains 687. The upper surface formed by the rollers 707 on the movable base 705 is configured to protrude above the upper surface of the chain 687 of the output side chain conveyor 680.

A chain 72 is wound between the sprocket 71 and a sprocket 72 connected to the rotating shaft of an electric motor 71 mounted below the frame 71. You. Therefore, when the electric motor 721 is rotated in a predetermined direction, the upper surface of the roller 712 disposed at the upper end of the frame 711 is synchronized with the direction of the arrow b ′ in FIG. It is rotated. The reference numeral 724 in the figure denotes a cleaning liquid receiving stand for receiving the cleaning liquid falling from the folding basket 1.

 In addition, an individual frame 7 25 is provided on the opposite side of the drive port 1-side conveyor 7 1 0 across the free port-side 1-side conveyor 7 01, that is, behind the output side tune conveyor 6 8 0. On the frame 7 25, and behind the upper side of the outlet side chain conveyor 6 80, there is a piston port 7 2 7 force. An air cylinder 726 extending to the end is provided, and a push plate 728 is attached to the tip of the piston rod 727. Further, a guide bar 7229 is protruded from the push plate 728 toward the upper side of the frame 7225, and a guide bar 7229 force is provided on the frame 7225. Connected to device 730. Accordingly, the folding basket 1 placed in the eighth station of the outlet side chain conveyor 680 in a stacked state is raised by the free roller conveyor 71, and in this state, the air cylinder 72 When the biston rod 7 2 7 of 6 is extended, the folding basket 1 in the stacked state is pushed by the push plate 7 2 8 of the piston port 7 2 7 and driven from the free roller compass 7 0 1. It is sent out on a moving roller conveyor 7110.

Also, in FIG. 28, the loading into the centrifugal dehydrator 800 described below is performed. To the right of the upper part of the drive roller conveyor 710 corresponding to the feed line C to the feeder 7500, a piston rod 732 extends from the drive roller conveyor 710 to the left, and an air cylinder 731 force, which drives It is provided on a frame 733 provided on the right side of the roller conveyor 710, and a push plate 733 is attached to the tip of the bit rod 732. Further, a guide bar 735 is provided to project upward from the push plate 733 toward the frame 733, and the guide bar 735 is provided with a guide device 7 provided on the frame 733. It is communicated to 36. Therefore, when the folding rod 1 in the stacked state is placed at a position corresponding to the delivery line C of the drive roller conveyor 7110, when the piston rod 732 of the air cylinder 731 is extended, The folding basket 1 in the stacked state is pushed by the push plate 734 of the piston rod 732 and sent out from the drive roller conveyor 7110 to an insertion device 7500 to a centrifugal dehydrator 800 described later. It is.

As described above, while the folding baskets 1 in a stacked state are placed on the eighth station of the outlet-side chain conveyor 680, the air cylinders 720 are extended to move the moving racks 705 together. When the free roller compensator 701 is raised, the folding basket 1 previously mounted on the chain compensator 680 is transferred onto the free roller compensator 701. In this state, the piston rod 7 27 of the air cylinder 7 26 is extended, and the folding basket 1 in the stacked state is moved from the free roller conveyor 70 1 to the drive port 1 on the roller conveyor 7 10. The folding basket 1 is transported to a delivery line C to the insertion device 750 by sending the folding basket 1 by driving the electric roller conveyor 710 by rotating the electric motor 721. Then, the piston rod 732 of the air cylinder 731 is extended, and the folding basket 1 in the stacked state is sent out to the insertion device 7500 into the centrifugal dehydrator 800. Therefore, Are alternately performed by the transfer device 700 provided on each of the two transport lines as described above, so that the two lines A and B become one line to the insertion device 7500.
