Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for unpacking a pallet in which synthetic fiber packages, etc. from a spinning winder factory are packed in a box in a drawing false twisting machine factory, etc., and separating them into individual packages to convey them to a predetermined position. The present invention relates to an unpacking transfer system for packages.

[0002]

2. Description of the Related Art For example, in a spinning winder factory, a synthetic fiber package is wound and formed through a spinning process. After going through the inspection process for this synthetic fiber package, it is packed in a box in the packing process,
Once stored in automated warehouses, etc., they are shipped to the draw false twister factory. An example of the structure of the pallet thus shipped will be described with reference to FIG. Pallets 21 are stacked in 4 layers and 3 in 1 layer
A package P of 12 pieces × 4 rows = 12 pieces is erected, placed in a grid pattern and packed in a box, and has a base plate 22b and a floor plate 22c.
Consisting of a bottom plate 22, three middle plates 23, a top plate 24,
It consists of the surrounding wrapping film 25. The number of the intermediate plates 23 is changed to 2 to 4 as needed. Then, the base plate 22c of the bottom plate 22 has an upward protrusion 22a,
The middle plate 23 has an upward protrusion 23a and a downward protrusion 23b.
However, the top plate 24 has the downward projection 24a, and the projection is fitted into the bobbin B of the package P in the upright state, and the position where the package P is placed is determined.

A case in which the pallet 21 is unpacked and the package P is mounted on, for example, a creel device of a draw false twisting machine will be described with reference to FIG. The creel device 26 is a rotary type, and has six rotatable peg shafts 27a to 27 in a single stage.
f is provided. In the illustrated example, the package Pb inserted into the peg shaft 27b is in the unwinding state, and the state immediately after the spare package Pa is inserted into the peg shaft 27a is shown. Then, unwind the bunch winding 20 of the package Pb,
The yarn end of the package Pa is spliced, and the peg shaft 27a is swung into the creel device 26 to finish the work. In order to connect the yarn to the bunch winding 20, the package mounted on the creel device 26 needs to be inserted into the peg shaft from the side where the bunch winding 20 is applied. Therefore, the bunch winding 20 of the package P is required to face downward even in stacking in the pallet. The reason is that when automating the mounting of the package P on the creel device 26, it is necessary that the bunch winding 20 always exists in a certain direction, and if the bunch winding 20 is downward in the pallet 21, a natural flow occurs. This is because the package P having a predetermined orientation can be mounted on the creel device 26. Therefore, the pallet 21 of FIG. 7 accommodates the package P with the bunch winding down.

[0004]

As described above, for example, an overhead conveyor or a self-propelled peg stand is used to convey the oriented package to the creel device of the draw false twisting machine. Therefore, unpack the pallet,
It is necessary to transfer each package to the overhead conveyor or the hanger of the peg stand. This work is usually done manually. This is because the packages placed on the bottom plate and the middle plate are arranged in multiple rows of a plurality of rows, and it is necessary to recognize and pick up the package positions in a wide range, for example using an articulated robot. If so, it becomes large and the position of the package to be picked up is not determined.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to open a pallet in which a plurality of packages are arranged in a single row. An object of the present invention is to provide an unpacking and conveying system for packages which can be packaged and automatically transferred and conveyed.
