PURPOSE: To provide a corrugated sheet-packaging device with a favorable work efficiency, which can be operated by an unmanned control. CONSTITUTION: Corrugated sheets 9 which are loaded on a pallet 1 are tied by a specified number with a band, and the corrugated sheets 9 tied by the band are re-loaded on the pallet 1 by a corrugated sheet-packaging device. Such a corrugated sheet-packaging device is constituted of a transfer machine 6 with a mechanism which draws up the corrugated sheets 9 being already stacked on the pallet 1 by vacuum suction and accumulates a specified number of the corrugated sheets 9, band-placing machine 23 which places a band on the accumulated corrugated sheets 9 in the corrugation direction, loading machine which loads the tied corrugated sheets 9 on the pallet again, and pallet- correcting machine which performs a positional correction of the pallet 1 loaded with the corrugated sheets 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated sheet packing apparatus for automatically taking out a plurality of corrugated sheets stacked on a pallet one by one, accumulating a predetermined number of sheets, banding them, and loading them again on the pallet. Regarding

[0002]

2. Description of the Related Art Conventionally, a predetermined number of sheets are taken out from a corrugated sheet loaded on a pallet, and the end faces are aligned and usually 2 in a corrugating direction.
Most of the work involved banding books, transporting them in the direction perpendicular to the corrugation direction, and then loading them onto a pallet with a loading machine was done manually.

[0003]

In the packaging of corrugated sheets, since the corrugated sheets loaded on the pallet are banded, a predetermined number of corrugated sheets must be accumulated to align the end faces. However, this kind of work requires a lot of manpower,
Particularly, when the corrugated sheet is relatively long, it requires an excessive amount of labor, and there is a problem in terms of workability and labor cost. Therefore, the present invention is intended to provide a corrugated sheet packing device which can perform this work unattended and has high work efficiency.

SUMMARY OF THE INVENTION The gist of the present invention for solving the above-mentioned problems is to use a corrugated sheet packing apparatus for banding a predetermined number of corrugated sheets loaded on a pallet and loading them again on the pallet. A transfer machine having a mechanism for sucking up the corrugated sheets loaded on top by vacuum suction and accumulating a predetermined number of sheets, a banding machine for banding the accumulated corrugated sheets in the corrugating direction, and a loading machine for reloading on the pallet again. It is a corrugated board packing device consisting of a pallet corrector that corrects the position of a pallet loaded with corrugated boards.

The corrugated sheet packing device of the present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. Figure 1
The structure of an apparatus used for carrying out the present invention and the flow of packing work are shown by arrows. The pallet 1 on which the corrugated sheets are loaded is placed on the conveyor 2 and sent to the next pallet correction machine 3. When the pallet 1 is placed on the conveyor 2, it is preferable to place the pallet on the left side because the entire device is designed with the left side facing the traveling direction as the reference surface.

On the pallet correcting machine 3, conveyors 4 and 5 are attached separately on the left and right sides, and the bending of the pallet 1 is corrected by reversing them. This is to prevent a suction mistake of the suction pad 10, and the pallet 1 can be accurately stopped at the reference surface by moving the entire conveyors 4 and 5 to the left and right by driving the motor. The pallet 1 whose position has been corrected by the pallet correcting machine 3 is sent to below the transfer machine 6 by the conveyors 4, 5 and 8 and the lifter 7 causes the uppermost surface of the corrugated plate 9 loaded on the pallet 1 to move. The suction pad 10 attached to the transfer machine 6 is raised to the suction position. In addition, the corrugated plate 9 during transfer
Is lifted by the lifter 7 so that the uppermost surface of the is always held at the suction position.

As for the corrugated plate 9 that has risen to the suction position, the uppermost one of the corrugated plates is sucked up by the suction pad 10 by the suction blower. The suction pad 10 is shown in FIG.
As shown in, the cross-section is circular or elliptic bowl-shaped,
A sponge 28 is adhered on its inner peripheral surface with a double-sided adhesive. Two sponges 28 are attached to the head plate 11 at intervals narrower than the width of the corrugated plate. It moves up and down by the cylinder 13 for.
These are unitized, and three units are mounted on the overhanging arm of the unit base 15 by the guide plate 14. With respect to the unit of this suction pad, two units from the left in the traveling direction are always used, and the remaining one unit is used for a long corrugated plate (9 or larger).

Next, a transfer machine constituting the corrugated board packing device of the present invention will be described. The unit base 15 on which the unit of the suction pad 10 is mounted is the same as the linear guide rail 1.
2 sets installed on 6 and slidable by the air cylinder 17, and the corrugated plate adsorbed on the adsorption pad is corrected table 1
Reprinted on 8. The two sets of unit bases have overhanged and offset arms to avoid interference with each other. The operation of transferring the corrugated sheets adsorbed to the adsorption pad 10 to the correction table in this manner is repeated until a predetermined number of corrugated sheets are accumulated. The corrugated sheet in which a predetermined number of sheets are accumulated is subjected to the final position correction with respect to the reference plane and the bend on the correction table 18 by the side face correction plate 19 and the end face correction plate 20.

As shown in FIG. 2, the side surface correction plates 19 are installed at a total of six places on the left and right, and the link mechanism and the air cylinder 1 are installed.
7, the end surface correction plate 20 fixes the reference surface side,
On the other side, the end surface is corrected by pushing the air cylinder 17. When corresponding to the length of the corrugated sheet product, the air cylinder 17 is slid on the linear guide rail 16 by the motor and the ball screw.

The position-corrected corrugated sheet is moved down to the correction table 18 by the cylinder 21 and is moved to the banding machine 23 by the conveyor 22, where it is banded in the corrugating direction. The banded corrugated sheet is moved to a predetermined position by the conveyor 24. After the movement, the entire conveyor 24 is moved forward by driving the motor, and the conveyor 24 is rotated in the reverse direction to load the banded corrugated plate on the pallet 26 on the lifter 25 which has already been raised to the loading position.

Then, the lifter 25 is gradually lowered so that the uppermost surface of the loaded corrugated plates is always constant. After loading a predetermined number of banded corrugated sheets, the lifter 25 descends to the conveyor 27. The pallet 26 loaded with the banded corrugated plates is moved to a predetermined position by the conveyor 27 and is carried out by the forklift. The pallet 1 on the lifter 7 is lowered by the lifter 7 immediately after the transfer is completed, and the pallet 1 and the conveyor 2
By 8 the sheet is conveyed to the lifter 25 under the loading machine and is ready for the next loading operation. In this way, the corrugated board packing operation is repeated.

[0012]

According to the corrugated sheet packing device of the present invention, the corrugated sheets loaded on the pallet sent by the conveyor are surely transferred one by one, and after stacking a predetermined number of sheets, the corrugated sheets are again placed on the pallet. It is possible to provide a corrugated board packaging device that is highly useful in practical use because it can be loaded on a vehicle and can perform these steps unattended, workability can be improved, and labor costs can be reduced. Further, the corrugated plate can be reliably transferred by the sponge of the suction pad attached to the transfer machine.
