Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for processing a sheet material, and more particularly to a method for preventing the occurrence of scratches on the back surface of a sheet material when feeding the sheet material to a punch press machine, and setting up a step for measuring a sheet length. The present invention relates to a sheet material processing method and apparatus for shortening time and improving productivity.

[0002]

2. Description of the Related Art Conventionally, a method and an apparatus for processing a plate material are generally provided with a free bear table for carrying the plate material into a punch press machine for processing the plate material and for placing the plate material thereon to process the plate material. On the front side of the table, an uncoiler provided with a plate material in a coil shape, a leveler for smoothing the plate material from this uncoiler with a roller such as a straightening roll, a feed roller for feeding the plate material, and a feed roller for feeding the plate material Shearing for shearing the cut plate material is provided.

The plate material sheared by the shearing is sucked by a suction pad provided in a single-sheet work loader. Further, the plate material is conveyed on the free bear table in the direction of the punch press as the single work loader advances by the servo drive mechanism. The length of the plate material is measured by calculating the amount of movement of the plate material by a servomotor, an arithmetic unit, and the like in this transport process.

[0004] As another method of measuring the length of a plate material, it is possible to measure the length by a measuring roll before shearing by shearing, and to shear by shearing to a desired length.

[0005] A locate pin is provided in front of the free bear table in the work loading direction to abut the tip of the plate material. When being loaded by the single work loader, the plate material is released just before the locate pin, and is then abutted against the locate pin by the origin setting pad to determine the origin.

[0006] The plate material positioned at the origin is gripped by a work clamp provided on a free bear table and supplied to a punch press.

[0007]

In a conventional punch press, however, the length of the plate is measured by calculating the amount of movement of the plate using a servomotor, an arithmetic unit, or the like. There has been a problem that the cost of the length measuring device increases and the length of the length measuring time increases, so that the production cost increases.

Further, there is another problem that when a length of a plate material is measured by a measuring roll, a length measurement error occurs, so that it is necessary to correct the length.

Further, when the plate material is transported on the free bear table, there is a problem that the plate material is damaged by friction with the free bear.

[0010] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to prevent the occurrence of scratches on the back surface of a plate material when feeding the plate material to a punch press, and to reduce the length of the plate material.
