2. Description of the Related Art For example, packages from a spinning winder are subjected to yarn end treatments such as surface treatment and bunching, inspection of shape and weight, and labeling before being temporarily stored in an automated warehouse. During this storage, the packages are stacked on pallets.

Next, the shape of this pallet is shown in FIGS. 4 to 6.
This is explained by: They are stacked in four tiers as shown in FIG. 4, nine packages P are lined up in one tier as shown in FIG. 5, and the package is box-shaped as a whole as shown in FIG. 6. As shown in FIG. 4, the pallet 1 includes a bottom plate 2, three middle plates 3, a top plate 4, and a surrounding wrapping film 5. The bottom plate 2 has an upward protrusion 2a, the middle plate 3 has an upward protrusion 3a and a downward protrusion 3b, and the top plate 4 has a downward protrusion 4a, and these protrusions are fitted into the bobbin B of the package P. Then, the package P is positioned.

By the way, the pallet 1 packed as shown in FIG. 6 is once transported to an automated warehouse and then transported to a stretch false twisting machine factory for each type, where it is unpacked and the packages inside are separated into each stretch false twister. Transported towards the machine. The wrapping film 5 of the pallet 1 is disposable, but the bottom plate 2, middle plate 3, and top plate 4 are molded plastic products and are not disposable but reused. Therefore, when unpacking, the pallet transfer device first transfers the top plate 4 to a predetermined first position. The package transfer robot sequentially transfers the topmost packages to the transport device. The pallet transfer device transfers the intermediate plate 3 to a predetermined second position. The package transfer robot sequentially transfers the packages in the middle row to the transport device. The pallet transfer device transfers the bottom plate 3 to a predetermined third position. in this way,
The top plate 4 is collected at the first position of the pallet transfer device, the middle plate 3 is collected at the second position, and the bottom plate 2 is collected at the third position. Then, the top plate 4 in the first position, the middle plate 3 in the second position, and the bottom plate 2 in the third position are each separately transported again to the spinning winder factory, where they are combined with a similar pallet transfer device and package transfer robot. Accordingly, bottom plate 2, package, middle plate 3
, the package, and the top plate 4 are packed in this order.

[0005]

The pallet transfer apparatus described in the prior art section is based on the premise that the bottom plate 2, middle plate 3, and top plate 4 are transferred separately. Therefore, the bottom plate 2, middle plate 3, and top plate 4 are each separated and stored or transported separately. Therefore, since the three types of products are handled separately, the storage or transportation process becomes complicated, which poses a problem that it is difficult to automate.

[0006] The present invention has been made in view of the problems of the prior art, and its purpose is to unpack or unpack the bottom plate, middle plate, and top plate of a pallet in an easy-to-handle manner. The purpose is to provide a pallet transfer device for packaging.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the pallet transfer device of the present invention packages a pallet in which packages are stored in a stacked manner between the bottom plate, middle plate, and top plate. A pallet transfer device that sequentially transfers each plate material when unpacking or packing via a transfer robot, wherein the pallet transfer device transfers the top plate to the inside while the package transfer robot is operating. It has an intermediate transfer place where the plates are transferred in order, and a final transfer place on the last bottom plate where the middle plates are transferred in order, and then the top plate.

[0008]

[Operation] When unpacking a pallet, the top plate and middle plate are stacked in that order at an intermediate transfer location, and then at the final transfer location, the bottom plate and
The middle plate and top plate are stacked as a set and transported or stored as a set. When packing a pallet, it goes from a set state to an intermediate transfer location where the top plate and middle plate are stacked in that order, and then at the final transfer location, the pallet is made up of the bottom plate, middle plate, and top plate in that order.
