The present invention relates to a furniture leather perforation device for improving productivity.

In general, furniture such as chairs and sofas are used when a user sits down or rests or works. The furniture includes a seat on which the user sits and a back part on which the user leans back.

Among these chairs and sofas, not only can the design be luxurious and comfortable, but also the chairs and sofas are made and sold using leather that gives a classic feel. These chairs and sofas are made of leather Because it is made of materials, it is sufficient to give a feeling of classic and luxury furniture, but there is a problem in that the structure of combining leather with a chair or a sofa frame is not easy.

However, in order to embed the decorative pins on the leather, it is necessary to puncture the holes so that the decorative pins are embedded in the leather. Therefore, the work having to puncture the holes in the thick leather is very difficult, resulting in a large drop in productivity and workability.

In other words, in order to drill a hole in the leather, the worker generally has to drill a hole manually by using a punching tool such as an awl, so that a large amount of force is applied to the wrist of the worker in order to drill thick leather with a drilling tool such as an awl. This has to be demanded, so there is a problem that the wrist is followed by a large crowd.

In addition, the hole between the perforated hole and the hole is not uniform because the holes are drilled in the leather depending on manual labor, and the spacing of the decorative pins does not remain constant with each other. There is a problem that impairs the appearance of the sofa or the high-end design of the chair.

In addition, as the worker perforates the leather manually by hand, there is a problem that the work efficiency is greatly reduced, and the productivity is also significantly reduced.

And the first and second adhesive rollers to superimpose the upper and lower bands to each other and the wires (copper wires) are wound, and the first and second adhesive rollers are positioned so that the wires are positioned in a plurality of contact holes formed in the upper bands, respectively. When the lower band overlaps each other, the first and second wire winding rollers for automatically feeding the wound wire and the upper and lower bands overlapped by the first and second adhesive rollers are perforated in the coupling holes and the contact holes. It is comprised by the limit switch which switches to maintain the space spacing of the engagement hole and contact hole by a cylinder after determining a state.

As another example, a punching machine having an easy adjustment of the drilling interval, which is registered utility model No. 20-0306951, has been devised, which has moving paths formed on both sides of the body part, and inserted into the moving path to move up and down by manipulation of the handle. In the perforator is fixed to the connecting shaft by the connecting rod, the bottom and front region of the moving shaft is provided with a detachable puncturing interval adjusting device for adjusting the puncturing interval of the puncture blade, the puncturing interval adjusting device, the movement Containing means formed in the bottom surface and the front region of the shaft and a holder member detachably inserted into the receiving means, the receiving means is formed in the front region in communication with the horizontal long hole formed on the bottom of the movable shaft, the horizontal long hole And a stepped groove having a locking piece formed therein, and a horizontal rotating groove formed at an upper portion of the stepped groove, and having a locking jaw formed at both upper and lower sides thereof. Consists of a horizontal locking groove formed on the top of the horizontal rotating groove.

Such prior arts allow holes to be drilled in the member to be drilled more easily, and holes to be drilled are drilled at a predetermined interval, but there is a problem in that installation costs are increased as the components are complicated.

In addition, there are problems of frequent failures caused by many components, and it is difficult to drill holes in thick members such as leather because most punching devices are used only to punch thin members such as paper or cloth. There is a problem.
