Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper chip removing apparatus for removing chips formed on a peripheral portion of a paper which has been punched.

[0002]

2. Description of the Related Art Punching may be performed on a paper on which a label or the like is printed or a paper for assembling a predetermined three-dimensional shape such as a box. The punching process is performed by making a cut along a contour line of a developed view shape of a label or a box by a press operation of a press machine equipped with a cutting blade. Generally, the punching process is rarely performed at the same time as the printing, and it is usual that the punching process and the printing process are performed at different times. However, when punching out a development view shape such as a plain box, printing is not performed and only punching processing is performed.

By the way, in the punching process, all the contour lines may be cut to obtain punched products on the spot. However, in this case, the punched products are scattered on the punching site and are collected and arranged. It takes time and labor to carry out the work, and the subsequent transfer work and quantity management at the time of shipment become complicated.Therefore, a punching process that forms a small uncut portion that is commonly called a blade stopper is performed. To be done. In this way, the punched product is not separated from the sheet even if the punching process is performed, so that the subsequent handling can be performed on a sheet-by-sheet basis, which is convenient.

However, with respect to the sheet shipped with the blade stopper formed, it is necessary for the user side to perform a work of removing an ear portion (hereinafter referred to as a tip portion) formed around the punched product. Conventionally, such chip removal work was carried out by placing punched products in a stacked state on a base and hammering the chip part with a hammer, but such work is very troublesome. In addition, it takes a lot of time, and tending to tendonitis is often caused by engaging in such work all day long, and improvement of the work method has been desired.

Under these circumstances, the one in which the chip portion is mechanically removed in recent years is disclosed in Japanese Patent Laid-Open No. 3-14220.
No. 0, Japanese Patent Laid-Open No. 4-87799 and the like are proposed.

In the chip portion removing apparatus described in Japanese Patent Laid-Open No. 3-142200, the punched sheet stack is placed on a pedestal having a planar shape of the punched article, and the chip section is placed from above. The punching tool for pressing is lowered. By doing so, the chip portion is separated downward, the stack of punched products remains on the pedestal, and the chip removal is completed.

Further, the chip removing device described in the above-mentioned Japanese Patent Laid-Open No. 4-87799 is constructed so that the pedestal rises in synchronization with the lowering of the punching tool. That is, the chips of the paper sandwiched between them are removed by raising the pedestal and lowering the punching tool.

[0008]

In the conventional chip removing apparatus described in the above publication, the punching tool is lowered with respect to the sheet placed on the base (Japanese Patent Laid-Open No. 142200/1993). ), The punching tool is lowered and the pedestal is raised (Japanese Patent Laid-Open No. 4-87799) to apply a vertical force to the chip portion of a sheet in which a large number of sheets are stacked. Therefore, there is a problem in that the power consumption of the press mechanism that operates the punching tool and the like increases correspondingly, and as a result, the operating cost of the chip removal process increases.

Further, since a plurality of stacked sheets are punched in the vertical direction, if the sheets are misaligned, the sheets will be broken without following the contour line of the punched product, and defective products will increase. Inconvenience occurs.

The present invention has been made in order to solve the above-mentioned problems, and the operating cost and the equipment cost do not increase, and the chip removal of the paper which can effectively suppress the generation of defective products. The purpose is to provide a device.
