Abstract

PURPOSE:To automate a packing task and save power by mounting a protection board on an upper face of a cut board to be packed and bringing margins of the protection board protruding from the cut board against four sides of the cut board for forming, thereby surrounding an upper face and sides of the cut board. CONSTITUTION:A carrier 5 for carrying a protection board 2 is provided freely automatically along a travel guide means hung above a conveyer line 6 and the protection board 2 for cut boards 1 which have been stacked by a plurality of pieces and packed in paper in a previous process. After the protection board 2 is mounted on the cut board 1 which has been positioned and stopped on the conveyer line 6, a forming plate 3 placed around the cut board 1 is tilted toward a side of the cut board from upward by an air cylinder, whereby margins of the protection board 2 protruding form the cut board 1 are brought against four sides of the cut board 1 for forming. Thus an upper face and sides of the cut board are surrounded by the protection board 1, and then a corner of the protection board 2 is folded into a V-shape by a triangular board 4 to obtain a predetermined figure.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting plate packing method and apparatus for carrying out metal packing of cutting plates such as cold rolled sheet steel plates.

[0002]

2. Description of the Related Art In recent years, due to the trend toward higher grades of cut sheet products such as cold rolled steel sheets, surface defects and rust during transportation have become a problem, and packaging has become necessary. In the conventional cut board packing line, the outer surfaces of several stacked cut boards are pre-packed with rust-proof paper, etc., and a box-shaped metal plate is placed over the paper to prevent damage from external impact or friction. It also prevents rustproof paper.

As the packing device, Japanese Patent Application No. 4-140 is used.
As proposed in Japanese Patent No. 147, a bent-box-shaped metal plate is used, the side surface of the metal plate is formed at right angles to the upper surface, and when mounted on a cold-rolled steel plate, the side surface of the metal plate is expanded outward. There is a device to be installed while.

[0004]

In the conventional packing method of the cut plate, the bent portion of the metal plate is formed vertically in order to make it adhere to the cut plate. However, when the cut plate is mounted on the cut plate, the cut plate is packed in a paper. Since the packing paper is bent at the end surface, it has some bulge.Be careful when covering the cut box with a box-shaped metal plate having a hanging part formed at a right angle to the upper surface. If not done, the metal plate could get caught in the paper and tear, so I had to attach it while watching the manual correction and the catch.

Further, since the lunch box-shaped metal plate is quite large, it is difficult for one person to handle, and the number of man-hours required for the packaging work is large. In addition, the above-mentioned Japanese Patent Application No. 4
In the one proposed in No. 140147, it is possible to automatically attach a metal plate to a cutting plate, but there is a problem that a device is complicated because a metal plate once vertically formed is spread and attached to the cutting plate. . The present invention provides a method of packing a cut plate and an apparatus for the same, which prevents generation of frictional flaws during transportation, is excellent in rust prevention, and is advantageous for labor saving.

[0006]

The gist of the present invention is as follows. (1) A protection pad plate having a size larger than that of the cut plate, which is the material to be packed, is placed on the top surface of the cut plate, and the extra portions of the protection pad plate protruding from the cut plate are pressed against the four side surfaces of the cut plate from above, and molded. A method of packing a cut plate, which is characterized in that a top face and four side faces of the cut plate are surrounded by protective backing plates by closely adhering to the side faces of the cut plate.

(2) A protective backing plate transporting device for transporting and placing the protective backing plate on the cut plate, and a tilting type for pressing the protective backing plate placed on the cut plate in the lateral direction of the cut plate to form the protective back plate. This is a cut-sheet packing device consisting of the molded plate of No. 1 and a triangular plate that folds the corners of the protective patch inside the side of the protective patch to form a triangular valley. (3) The cut plate packing device according to (2), wherein a slide mechanism is provided on the molding plate and the triangular plate so that the position can be changed according to the size of the cut plate.

[0008]

1 and 2 are a front view and a side sectional view illustrating the present invention. The transport device 5 that transports and mounts the protective backing plate 2 to the cutting plate 1 that is stacked on the conveyor line 6 and is pre-packaged in the paper in the previous process, and the protective backing plate 2 that is mounted on the cutting plate 1 are thin. It is a metal plate, and is prepared in such a size that the cutting plate 1 is not exposed even if it is bent from the upper surface to the end face of the cutting plate 1. The forming plate 3 of the protective backing plate 2 is tilted from above the protective backing plate 2 toward the side of the cutting plate by an air cylinder, and the protective backing plate 2 between them is pressed against the cutting plate 1 for bending.

Further, the forming plate 3 is arranged near the conveyor line 6 side, is slidable in the longitudinal and width directions in accordance with the dimensional change of the cutting plate 1, and is further bent in the width direction of the cutting plate 1. When the cutting plate 1 moves on the conveyor line 6, the cutting plate 1 is on the line and interferes with each other. Therefore, it is necessary to evacuate from the interference area due to the movement of the cutting plate 1, and the forming plate 3 in the width direction.
Requires a mechanism for moving the cutting plate 1 above the conveyor line 6 and the retracted position when the cutting plate 1 is moved. When forming the cut plate 1, the corners of the square are
It is necessary to make a valley fold inside the protective backing plate 2 formed on the side surface in the longitudinal direction, and a triangular plate 4 having a size matching the shape of the corner is provided on the forming plate 3 in the width direction.

The cut plate 1 placed on the conveyor line 6 and pre-packaged with paper in the previous step is conveyed by the conveyor line 6 to the position of the molding plate 3. The protective backing plate 2 is the transport device 5
Then, it is positioned so as to come to the center of the cut plate 1, and is conveyed to the top of the cut plate and lowered and placed. The part of the protection pad plate 2 that protrudes from the upper surface of the cut plate 1 is bent by being pressed against the cut plate 1 from the upper surface by the molding plate 3 and adheres to the side surface of the cut plate 1 so that the upper surface and the end surface can be packed.

At this time, the corner portion of the protective pad 2 is the triangular plate 4
Since it is valley-folded in the line direction and enters the inside of the protective backing plate 2 that is bent on the side surface of the cutting plate, it does not stick out from the side surface and can be prevented from being caught at the time of transportation, and it also has a good packing form. It can be anything.

[0012]

EFFECTS OF THE INVENTION According to the present invention, the work of covering the cutting plate with the protective backing plate can be automated, which is not only advantageous in terms of labor saving but also leads to the safety of the work and further the cutting plate. Since the top surface and four side surfaces can be covered with a metal plate, it is possible to prevent scratches and frictional flaws due to impact during transportation, protect rustproof paper, and ensure rustproofness. In addition, since the protective backing plate is molded after mounting, positioning at the time of mounting can be eliminated.
