Problems solved by technology

[0008] Therefore, when one figure is cut and moved to the next figure, the scissors are raised more than necessary, so in the process of cutting a plurality of figures, the movement time accompanying the scissors' rise is accumulated, and there is a cut. The problem of reduced efficiency

Embodiment Construction

[0119] Below, based on Figure 1 to Figure 5 One embodiment of the sheet cutting device of the present invention will be described.

[0120] figure 1 It is a partially cutaway perspective view showing the whole of the sheet shearing device of the present invention. As shown in the figure, the sheet cutting device 1 is provided with a cutting table 2 formed of bristles 3 on the upper surface of a cutting machine body 80 serving as a suction box. Sheets 7 of woven or non-woven fabrics, leather, carbon fiber materials, etc. are stacked on the cutting table 2, and the surface thereof is covered with an airtight vinyl sheet 8 as needed, so that the above-mentioned sheets Material 7 attracts and remains on the surface of above-mentioned shearing workbench 2.

[0121] In addition, a Y-beam 4 is suspended perpendicularly to the X direction (longitudinal direction) on the upper portion of the shearing table 2, and the Y-beam 4 can move freely in the X direction. A shearing head 10 ...

Abstract

The invention provides a sheet material shearing device. The sheet material shearing device eliminates useless lifting of a sheared knife and the shearing efficiency is raised. A sheared head is composed of a sheared head fixing frame, a sheet material pressing mechanism, a lifting frame, a sheared knife reciprocating motion mechanism arranged on the lifting frame, and a sheared knife lifting unit lifting the lifting frame between a first position of the uppermost end and a second position of the lowest end. The sheet material pressing mechanism is arranged on the fixed frame separating from the lifting frame, and comprises a sheet material pressing member lifting unit and a detection plate lifting together with the sheet material pressing member. The lifting frame comprises a sensor, for detection, of the detection plate. Detection is carried out in a third position where the knife point between the first position and the second position and the bottom surface of the sheet material pressing member separate at a special interval when the lifting frame rises to the third position, through detection of the sensor, rising of the lifting frame is stopped, and the sheared head can move in the shearing pattern.

Description

technical field [0001] The present invention relates to a sheet cutting device which cuts stacked sheets into a desired shape, and more specifically, relates to a sheet cutting device which controls the lifting amount of the shearing knife when cutting stacked sheets. Controlled, efficient cutting. Background technique [0002] Conventionally, it is known that sheets are stacked and sucked and held on a cutting table, and a shearing head (equivalent to a cutter head) arranged to move horizontally is moved on the cutting table according to a pre-designed pattern while setting the cutting head. A sheet cutting device that cuts the sheet into a desired shape by reciprocating up and down the cutting blade on the cutting head (for example, Patent Document 1). [0003] In the sheet cutting device of this patent document 1, a sheet pressing member (equivalent to a pressing plate) is provided around the cutting blade so that the sheet does not rise when the cutting blade reciprocat...
