DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing / drying apparatus for a folding basket made of synthetic resin for carrying articles such as vegetables, fruits, and small parts.

[0002]

2. Description of the Related Art Conventionally, when goods such as vegetables and fruits or small parts are conveyed by a cargo transportation vehicle such as a truck,
A paper packing box such as a cardboard box is used, and articles are packed and packed therein, and after using the articles, the paper packing box such as the cardboard box is discarded. In recent years, such paper boxes have been collected and reused.However, such paper boxes are often soiled or broken during transportation or the like. It is still expensive and very disadvantageous both economically and resource saving.

[0003] Therefore, such a transport container is made of synthetic resin such as plastic, and it is being surely reused. 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 a basket, even though the inside is empty, for example, at the source of the article, unnecessary space becomes large. In addition, waste is likely to occur in terms of a freight transport vehicle for transporting the vehicle and a stocker yard for storing the vehicle. 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, for example, to the source of the article as described above. It is considered that no useless space is generated when the sheet is transported. Such a foldable basket made of a synthetic resin is hereinafter simply referred to as a foldable basket, and such a foldable basket includes, for example, a product made by "Ifco Japan Co., Ltd."

[0004] FIG. 39 briefly shows the use state of the folding basket. In this folding basket 1, as shown in FIG.
With respect to the rectangular bottom member 1a, a side wall (hereinafter also referred to as a short side wall) 1b corresponding to its short side and a side wall (hereinafter also referred to as a long side wall) 1c corresponding to its long side stand vertically. From a fully opened state (hereinafter also referred to as a fully opened state), first, as shown in FIG. 2B, the short side wall 1b is folded inward (hereinafter, this state, that is, only the long side wall 1c is opened). The state in which the basket 1 is closed is also referred to as a half-open state), and then the long side wall 1c is folded inward as shown in FIG. Becomes If the sheet is conveyed to, for example, the conveyance source in the closed state or the folded state, no useless space is generated. Then, when used as the basket 1, contrary to the above, open the side walls in the order of the long side wall 1c and the short side wall 1b,
The basket 1 in a completely opened state can be formed. 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.

[0005]

However, such a folding basket 1 made of synthetic resin, when carrying goods such as vegetables and fruits as described above, for example, also stains the inside and outside of the basket. Would. Naturally, the folding basket 1 thus contaminated needs to be cleaned before reuse, but in the past, these baskets were opened one by one, and the inside was manually cleaned. However, this requires not only a troublesome cleaning operation but also an enormous amount of time required for cleaning. Then, the present applicant sets the folded basket in a closed state upside down, that is, puts one by one with the bottom member 1a facing upward, and automatically sets it in a half-open state, and sprays the cleaning liquid from inside and outside. We have developed an automatic cleaning device that removes the adhered dirt with a cleaning solution and then sends it out again in a closed state.

[0006] However, since this automatic cleaning device merely cleans the folding basket, a 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 wrapped with synthetic resin wrapping material. Although it is desirable to perform, it is impossible to send out to the next step until the folding basket which has been sent out from the washing device has been dried, since the washing liquid is likely to adhere to the folding basket, and the yield during that time decreases. I do.

The simplest method for efficiently drying such wet articles is so-called blower drying, in which hot air is blown. However, while the temperature of the hot air at which the cleaning liquid, whose component is mostly water, is efficiently dried is 100 ° C. or higher, the synthetic resin folding basket has a lower mechanical strength at lower temperatures. Because of this, the blower drying cannot be used for drying the folding basket made of synthetic resin due to thermal deformation. Also, 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,
Since only a narrow slit is formed in the folded basket in the closed state, it is difficult for the wind to pass through the inside of the folded basket in the closed state, and it is difficult for the wind to dry.

The present invention has been developed in view of these problems. The folding basket delivered from the washing device can be efficiently and completely removed without thermally deforming or reducing the mechanical strength. It is an object of the present invention to provide a folding basket cleaning / drying apparatus capable of improving the yield by drying.

A push plate 554 having a central portion connected to the piston rod 552 and both end portions connected to the guide device 553.

Therefore, the inverting drainer 500 operates as follows. However, here, 9
Only the operation of one of the four transport claws 537 protruding at every 0 ° will be described in detail, and the other transport claws will act similarly when the rotation shaft rotates by 90 °. The detailed description is 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 is shortly between the openings of one of the transport claws 537 of the reversing device 530 that are waiting to face the belt conveyor 512 on the entry side. And is brought into contact with the template 539. When the folding basket 1 comes into contact with the template 539 in this manner, the rotation axis of the reversing device 530 is rotated in the direction of the arrow r (u) in FIG. 19 so that both end portions in the width direction of the folding basket 1 are sandwiched. The supported transport claws 537 are rotated in the same direction. Thereafter, when the rotation shaft 534 and the transport claw 537 of the reversing device 530 are in the vertical or almost vertical position in the rotation direction, the upper end of the folding basket 1 is in contact with the contact plate 547. As shown in FIG. 19, the template 539 which has supported the folding basket 1 from below with the outer peripheral surface 539a having the same radius of curvature is changed to the folding basket 539b with the smaller radius of curvature via the vertical surface 539c. 1 is supported from below, and during this time, the folding basket 1 becomes the outer peripheral surface 539b of the template 539 having a small radius of curvature.
The cleaning 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, is effective along the outside. Is shaken off.

Even when the folding basket 1 falls in this manner, the folding basket 1 continues to be further rotated in the direction of the arrow r (u), with both sides in the width direction being sandwiched by the transport claws 537. By the way, even if the contact plate 547 is kept in contact with the folding basket 1 and is thereby pushed and moved in the rotation direction of the folding basket 1, when the contact with the upper end of the folding basket 1 is lost, The extension spring 548 hangs back. 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 / falling claw 5 is extended.
As shown by a two-dot chain line in FIG. 17, when the U-shaped upper end portion 544a is positioned inside the transport line, the plate for locking the transport claw 537 which is continuously rotated is provided. 538 comes into contact with the roller 545 at the upper end 544a of the locking / dropping claw 544, and cannot move any more in the rotation direction. At the same time, the air motor 531 that rotates the conveyance claw 537 and the rotating shaft 534 also stops. However, the air motor 531 has an allowable range of compressive deformation of the supplied air, that is,
Since a slight phase difference is allowed within the allowable range of the air pressure for driving the drive 31, when the piston rod 542 of the air cylinder 541 of the transport claw locking / falling device 540 is contracted within that range, the locking / falling is performed. The claw 544 rotates about the support point of the bracket 543, and as shown by a solid line in FIG. 17, the U-shaped lower end 544b moves inside the transport line, and the upper end 544a is Since the transport claw 537 is disengaged from the locking plate 538 to the outside, the transport claw 537 whose movement in the rotation direction has been restricted until then is rapidly moved in the drop direction by the air pressure compressed in the air motor 531. Rotate. Then
The folding basket 1 held by the transport claws 537 is hit on a belt conveyor 513 at the next central portion, and the slight impact of the folding basket 1 also shakes off the cleaning liquid attached to the folding basket 1. . At this time, the cleaning liquid adhering to the surface of the belt conveyor 513, in particular, is effectively shaken off.

At this time, the U-shaped lower end portion 544b of the locking / falling claw 544 of the transport claw locking / falling device 540 is connected to the locking plate 53 of the transport claw 537.
8 so that the transport claw 537 does not rotate below it. Then, the piston rod 542 of the air cylinder 541 of the transport claw locking / falling device 540 is extended again, and the locking / falling claw 544 is extended.
The U-shaped lower end 544b is removed from the outside of the transfer line to enable the rotation of the transfer claw 537, and the upper end 544a is provided on the next transfer claw 537 and is moved inside the transfer line. Let it be. At this time, the folding basket 1 is inverted so that the bottom member 1a faces downward, contrary to the previous transportation.

On the other hand, the belt conveyor 513 in the central portion
The folding basket 1 hit on the upper side is transported as it is in the direction of the arrow t by the belt conveyor 513 at the central portion, and sent to the next reversing device 530. In the reversing device 530, the transport claw 53 is provided in the same manner as the reversing device described above.
While the folding basket 1 is inverted by 7, once the folding basket 1 falls along the template 539 at a position where it is vertical or almost vertical, the cleaning liquid still attached to the folding basket 1 is shaken off. Then, the folding basket 1 is hit against the next belt conveyor 514 on the exit side, whereby the cleaning liquid still attached to the folding basket 1 is shaken off. In this way, the folding basket 1 inverted twice.
The bottom material 1a faces upward, as in the case of being sent to the entry side. Therefore, the pushing device 550
Expands the folding basket 1 sent out from the belt conveyor 514 on the delivery side by extending the piston rod 552 of the air cylinder 551 to the next stacking device 600.
The sheet is fed into the entrance belt conveyor 650 in the direction of the arrow w.
