Cutting machine and sheet feeding cutting method

Abstract

When a cutting machine which can execute feeding cutting to the sheet material is used for cutting the sheet material, the waiting time of cutting units of cutter, etc. can be reduced furthest for increasing the cutting efficiency even the long component is cut. After the former component is cut by sheet material feeding cutting, when the feeding cutting of sheet material of next component is subsequently executed, a determining unit determines whether the object part on the cutting line to be cut by the cutter enters the cutting area according to cutting data before the cutting of next component. When the determining result of the determining unit shows that the object part on the cutting line to be cut by the cutter has entered the cutting area, the feeding cutting of sheet material is executed next to the former component. When the determining result of determining unit shows that the object part on the cutting line to be cut by the cutter has not entered the part in the cutting area, an arithmetic unit calculates the cutting waiting time and the cutting waiting position of cutting head when the sheet material is fed without cutting, so that the object part in the cutting line to be cut by the cutter enters the cutting area. The feeding of sheet material is executed by a cutting control unit without shearing in the cutting waiting position and the cutting waiting time calculated by the arithmetic unit.

Description

technical field

[0001] The present invention relates to a cutting machine for cutting sheets of cloth, leather, etc. A cutting machine for cutting, and a sheet-feed cutting method. Background technique

[0002] As a sheet cutting method of an existing cutting machine that cuts a sheet while moving on a cutting table, for example, Patent Document 1 discloses a sheet feeding and cutting method, which is a method for cutting a sheet along a predetermined The method of cutting along the path constitutes a processing window with a preset length equal to or less than the length of the processing area in the advancing direction of the sheet, and by moving the processing window while the sheet is advancing, the cutting knife, etc. are processed. The tool moves in two directions (X-axis direction·Y-axis direction) within the determined processing window, and cuts the sheet while moving through each path within the processing window.
