DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse storage facility.

[0002]

2. Description of the Related Art When a load is stored in an automatic warehouse at a distribution center, the load is arranged by a load correcting machine before the storage is performed.

At this time, the cargo is transported by a truck or the like in a state in which cardboard boxes are stacked on the pallet (pallet packing), so that when the cargo arrives at the distribution center, the cargo has shifted or collapsed to the outside of the pallet. It is in a state. If you enter the automatic warehouse as it is, it will collapse during transportation or be caught on a crane or shelf, so that the load is corrected by the load-correction machine.

When the pallets are stacked vertically, the stack is disassembled into single pallets, and each single pallet is corrected sequentially by a packing corrector. After that, each pallet package whose packaging has been modified is to be sequentially stored.

[0005]

However, the prior art has the following problems. Stacked packages cannot be modified as they are. For this reason, it is necessary to always disassemble the pallet into a single pallet in front of the pallet corrector, and the warehousing efficiency is low.

[0006] In the case of stacked cargoes of the same type in which the cargo in each tier is of the same type, the garments are first disassembled as described above to correct the garbage, and then sequentially rectified, and then the individual shingles after the rectification are corrected. When the pallet packing is stored, the pallet will be restacked again, resulting in poor storage efficiency.

[0007] It is an object of the present invention to improve the storage efficiency of a staged package.

[0008]

According to the present invention, there is provided an automatic warehouse receiving apparatus for receiving a pallet loaded on a pallet according to claim 1, wherein the pallets are stacked vertically. In addition to having a package shape corrector that can correct at the same time, it has a type discriminator that can identify the type of load at each stage, and if the load at each stage is the same type, it can be stored as stacked. In addition, if the load in each stage is of a different type, a storage processing control device is provided which disassembles and stores the different types of products in different stages.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, there is provided a loading height control device which can detect a loading height of each stage. Is designed to make it possible to recognize the types of goods to be stored and their numbers based on the outputs of the type discriminator and the package height detector.

[0010]

[Function] It is possible to correct the stacked form at the same time up and down. For this reason, there is no need to disassemble the stacked packages into a single pallet package in front of the package modification machine, and the storage efficiency is high.

[0011] If the load of each stage is of the same type of stacked cargo, the cargo will be stored in the stacked state after being corrected. Therefore, the storage efficiency is good without the disassembly and re-stacking of the stacking.

Based on the outputs of the type discriminator and the package height detector, it is possible to easily recognize the type of the storage and the number thereof.

The stacked packages 1 (1A, 1B) can be simultaneously corrected up and down. Therefore, there is no need to disassemble the stacked packages 1 (1A, 1B) into the single pallet packages 1A, 1B before the package modification machine 100, and the storage efficiency is good.

If the loads 3 in each stage are of the same type of stacked cargo 1A, 1B, they will be stored in the stacked state after they have been modified. Therefore, the storage efficiency is good without the disassembly and re-stacking of the stacking.

The product type discriminator 400 and the package height detector 30
Based on the output of 0, it is possible to easily recognize the warehousing type and the number thereof.

In the case of the X-direction packing correction machine 100 and the Y-direction packing correction machine 200, each of the packing correction plates 131, 141.
Is performed in two stages. As a result, the cargo
If the pallets 2A and 2B are shifted to the outside as shown in (A), the shifted packing style plates 131 and 141 hit the cargo first, and the packing style correcting boards 131 and 141 are slowly moved by the load resistance. Even if it moves, the loading state correcting plates 131 and 141 do not complete the clamping of the load during the first stage pressing operation. Accordingly, both packing appearance correction plates 131,
When the first-stage pressing operation is completed, 141 always reaches the first pressing position that matches the outer edges of the pallets 2A and 2B (see FIG. 20B).

[0113] Then, the both appearance correction plates 131 and 141 are
The second pressing operation completes the pressing of the load within the width of the pallets 2A and 2B (see FIG. 20C). As a result, the packed cargo can be placed on both sides of the pallet 2
A, 2B will be accommodated (FIG. 20 (D)
reference).

That is, both the packing appearance correction plates 131 and 141 are 1
The load is brought closer to the outer edges of the pallets 2A and 2B by the pressing operation of the second stage, and the load is completed by the pressing operation of the second stage to complete the packing.

16 is similar to the above-described X-direction packing correction machine 100. In addition to the X-direction upper pallet lifting / lowering device 103, the lower pallet fixing device 104 and the upper pallet fixing device are mounted on the frame 101. 105, a lower-stage package appearance correction device 106, and an upper-stage package appearance modification device 107.
The difference between the packing correction machine 600 and the X-direction packing correction machine 100 is that the packing correction machine 600 includes a turntable 601 in place of the transport roller 102 and a Y-direction upper pallet lifting / lowering device 602. Pallet package 1 can be corrected in both the X direction and the Y direction.

The turntable 601 converts the pallet package 1 by at least 90 degrees. The Y-direction upper pallet lifting device 602 pushes a lifting lever 603, which is rotated by a lifting lever operating cylinder (not shown), into a through-hole 2C passing through the X direction of the upper pallet 2B turned 90 degrees by the turntable 601. Can be disengaged.

Therefore, in the packing appearance correcting machine 600,
The X-direction upper pallet lifting device 1 is inserted into the through-hole 2C of the upper pallet 2B placed on the lower pallet packing 1A arriving on the turntable 601.
03 of the upper pallet 2
By raising B, the upper pallet package 1B is separated from the lower pallet package 1A, and the upper and lower pallet fixing devices 104 and 105 and the upper and lower pallet fixing device 10 are separated.
6 and 107, the upper and lower pallet packages 1A and 1B are corrected in the X direction, and the upper and lower pallet packages 1A and 1B corrected in the X direction are returned to the turntable 601. The pallet packages 1A and 1B are turned by 90 degrees by turning the table 601, and the through-holes 2C of the upper pallet 2B placed on the lower pallet package 1A, which has been turned by 90 degrees, are used. The upper pallet 2B is raised by inserting the lifting lever 603 of the upper pallet lifting device 602 for Y direction into the same through hole 2C) as the insertion of the lifting lever 120 of the upper pallet lifting device 103 for X direction. Upper pallet package 1B
The upper and lower pallet packages 1A and 1A are separated by using upper and lower pallet fixing devices 104 and 105 and upper and lower pallet fixing devices 106 and 107 in a state where the pallets are separated from the lower pallet package 1A.
By correcting B in the Y direction and returning the pallet packages 1A and 1B corrected in the Y direction to the turntable 601, the correction in both the XY directions is completed.

That is, the packaging style correction machine 600 can correct the pallet packaging style 1 using the two-way difference pallets 2A and 2B in both the X and Y directions with one correction machine.

[0119] In addition, the packing state correction machine 600 has a packing state height detector 604 installed on its entry side, and the lower type reading device 605 and the upper type reading device 603 are mounted on the lifting lever 603 of the upper pallet lifting device 602 for the Y direction. A package height detector 604, a kind reader 605, 606.
, The form of the pallet package 1 is determined, and an appropriate correcting operation is performed on the various packages a to f (see FIG. 9) of the pallet package 1 in the same manner as in the storage facility 10 described above (see FIG. 16). (B)). Therefore, after the correction in the X and Y directions, if the upper and lower types are the same type, the upper and lower pallet packages 1A and 1B are stacked and the turntable 601 is stacked.
Return to the top and store at the same time, if the upper and lower varieties are different varieties,
The lower pallet package 1A can be returned to the turntable 601 first and paid out, and then the upper pallet package 1B can be returned to the turntable 601 and paid out. At this time, the lifting / lowering lever 603 of the upper pallet lifting / lowering device 602 for the Y direction descends to the turntable 601 side without buffering with the lower pallet correction device 106, and can transfer the upper pallet packaging 1B to the turntable 601.

17 is similar to the Y-direction packing apparatus 200 in that the upper pallet lifting apparatus 203, the lower pallet fixing apparatus 204, the upper pallet fixing apparatus 205, and the lower packing apparatus 206 are mounted on the frame 201. , An upper-stage package appearance correction device 207. And the packaging correction machine 7
00 differs from the Y-direction packing state correction machine 200 in that a turntable 701 is provided instead of the transport roller 202. As a result, the pallet 2 is
When a four-sided pallet is used as A and 2B, the pallet package 1 can be corrected in both the X direction and the Y direction with one correction machine.

The turntable 701 converts the pallet package 1 at least 90 degrees. Therefore, in the packing state correcting machine 700, the upper pallet is moved up and down into the X-direction through hole 2C of the upper pallet 2B placed on the lower pallet packing form 1A arriving on the turntable 701. By inserting the lifting lever 220 of the device 203 and raising the upper pallet 2B, the upper pallet packing form 1B is separated from the lower pallet packing form 1A and the upper and lower pallet fixing devices 204, 205, The upper and lower pallet packages 1 using the shape correction devices 206 and 207.
A, 1B are corrected in the X direction, and the pallet packages 1A, 1B corrected in the X direction are returned on the turntable 701, and the pallet packages 1A, 1B are rotated 90 degrees by turning the turntable 701. Turned 2 degrees, turned 90 degrees
By inserting the lifting lever 220 of the upper pallet lifting device 203 into the Y-direction through hole 2C of the upper pallet 2B placed on the lower pallet packing 1A of the stacked pallet packing 1, and raising the upper pallet 2B The upper and lower pallet packages 1A and 1B are separated by using the upper and lower pallet fixing devices 204 and 205 and the upper and lower package correction devices 206 and 207 in a state where the upper pallet package 1B is separated from the lower pallet package 1A. By correcting the pallet packages 1A and 1B corrected in the Y direction on the turntable 701 in the Y direction, the correction in both the X and Y directions is completed.

That is, the packaging style correction machine 700 can correct the pallet packaging style 1 using the four-way difference pallets 2A and 2B in both the X and Y directions with one correction machine.

[0123] In addition, the packing state correcting machine 700 has a packing state height detector 704 on the entry side thereof, and the lower type reader 7 is mounted on the lifting lever 220 of the upper pallet lifting device 203.
05 and an upper type reader 706, and the form of the pallet package 1 is determined based on the output of the package height detector 704 and the output of the type readers 705 and 706, and the pallet is loaded in the same manner as in the above-described storage facility 10. Various packaging styles a-1
f (see FIG. 9), an appropriate correction operation is performed (see FIG. 1).
6 (B)). Therefore, after the above correction in the X and Y directions, if the upper and lower varieties are the same type, the upper and lower pallet packages 1A and 1B are returned to the turntable 701 in a stacked state and stored simultaneously, and the upper and lower varieties are different types. If so, the lower pallet package 1A can be returned to the turntable 701 first and paid out, and then the upper pallet package 1B can be returned to the turntable 701 and paid out. At this time,
The lifting / lowering lever 220 of the upper pallet lifting / lowering device 203 moves down to the turntable 701 side without buffering with the lower pallet loading correction device 206, and can transfer the upper pallet loading 1B to the turntable 701.

It should be noted that in the above-described X-direction packing state correcting machine 100, a machine in which the transport roller 102 is replaced with a turntable may be used. However, in this case, the upper and lower pallet packages 1A and 1B stacked in two different varieties cannot be separated (stepped apart) after their correction.
