Problems solved by technology

In addition, when the cover sheet is used, in addition to the problem of being entangled in the cutting head, when the part is taken out from the cut material, it is troublesome to separate the cut piece of the part and the cover sheet.
When it is troublesome to separate 10 or more parts and the same number of cut-off pieces of the cover sheet, for example, in the case of taking out 60 parts from one piece of leather, even if the cover sheet is separated for each Parts take 2 seconds on average and also lose a total of 2 minutes

Embodiment Construction

[0026] Figure 1 to Figure 5 The cutting method and cutting apparatus of the embodiment are shown. In each figure, 2 is a cutting device, which consists of a cutting bed 4 and a computer 6 for control. The cutting bed 4 includes a gas-permeable pad 8 made of bristles or the like. The gas-permeable pad 8 is, for example, annular, and is rotated by a pair of pulleys 9 , 9 . The cutting bed 4 includes a vacuum pump 12 and a suction chamber 13 to suck air from the pad 8 . 14 and 14 are a pair of rails, and the rail 16 for moving the carriage 18 is moved by a moving motor not shown. The rail 16 supports a carriage 18, and the carriage 18 may move on the rail 16 by itself with a built-in motor, or may move by a driving source provided on the side of the rail 16, such as a timing belt.

[0027] The carriage 18 has a camera head 19 with a CCD camera and a cutting head 20 with a free-moving knife or a circular knife, and the heads 19 and 20 move on the cutting bed 4 in two-dimension...

Abstract

The present invention relates to a cutting method and a cutting device employing overlay pieces, wherein material to be cut is arranged on a cutting bed having an attraction source, is filmed to obtain the contour of the material to be cut, and is covered by a non-permeability overlay piece. Parts are arranged in the contour, and the material to be cut is cut into parts by a cutting head moving on the cutting bed. overlay pieces are cut according to cutting lines along the material contour, and parts is cut after removing the overlay pieces on the material. The overlay piece will not be coiled on the material to forbid the cutting, and the parts after cutting will not be separated from the overlay pieces.

Description

technical field [0001] The present invention relates to the cutting of non-breathable material to be cut such as leather or vinyl chloride sheet, and particularly relates to the use of a non-breathable cover sheet to prevent movement of the material to be cut during cutting. Background technique [0002] Patent Document 1 (JPH04-61108B) and Patent Document 2 (JPH10-8100A) describe a technical solution in which a material to be cut is covered with an air-impermeable covering sheet for cutting. The cutting bed of the cutting device has a vacuum source such as a vacuum pump, and the material to be cut is attracted and fixed on the vacuum bed. Here, if air is sucked from the periphery of the material to be cut to the vacuum source side, the suction porosity decreases. Therefore, the material to be cut is cut in a state where the material to be cut is covered with the air-impermeable covering sheet. [0003] However, the present inventors found that the following problems arise...
