Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a laminate cutting device that cuts a plurality of sheet materials such as cloth with a knife-shaped cutter.

[Prior art]

Conventionally, for example, as shown in Japanese Patent Publication No. 51-45113, a cutter head that moves in the X and Y directions orthogonal to each other is provided above a supporting member such as a brush table, and the tip end of the cutter head is disposed. There has been a laminate cutting device in which a sharp elongated knife-shaped cutter is mounted so that it can be raised and lowered and rotated about a vertical axis. In this cutting device, the cutter is lowered, and the cutter head is normally moved from the end of the laminate stacked on the support member to the X-axis.
By moving the cutter horizontally in the Y-direction and in the Y-direction, the cutter is moved, and the cutter is rotated around the vertical axis so that the blade edge is oriented in the moving direction, and the laminate is cut into a desired shape over the entire thickness direction. There is.

[Problems to be Solved by the Invention]

When cutting the laminate with the cutting device as described above, it may be necessary to insert a cutter into the laminate from above the laminate rather than from the end of the laminate to perform the cutting. Has the following problems. That is, when the laminate has a large thickness, the cutter may not be inserted vertically into the laminate, and may elastically deform to cause cutting deviation or damage the cutter. Especially,
A blade receiver is provided below the laminate, and the tip of the cutter is inserted into and supported by the hole of the blade receiver for cutting.
When the cutter bends, the hole of the blade receiving tool and the tip portion located below the cutter are displaced, and the cutter is easily damaged. In addition, when cutting the laminate with only the cutter,
As shown in the figure, since almost the entire side surface of the cutter 10 contacts the laminate, depending on the material of the laminate such as vinyl chloride or leather, the cut edge of the laminated sheet material may melt due to the friction caused by the vertical movement of the cutter. I have something to do. In order to prevent this, as shown in FIG. 7, a cutter guide 16 is provided at the rear of the cutter 10 to reduce friction with the laminate at the time of cutting, but this is because the cutter 10 and the guide 16 are at the same time. However, there is a problem in that it is impossible to penetrate the entire laminate due to the presence of the guide when inserting the laminate. The present invention solves the above-mentioned problems, and even if the cutter is penetrated into the laminate from an arbitrary position in the middle of the laminate, the cutter is not bent, the laminate can be accurately cut, and the cutter is damaged. It is an object of the present invention to provide a laminate cutting device that does not do so.

[Means for Solving the Problems]

According to the present invention, a cutter head that horizontally moves is provided above a support member that supports a laminate, and a knife-shaped cutter that moves up and down and rotates around a vertical axis is attached to the cutter head, and the cutter is attached to the support member. In a laminate cutting device equipped with a cutter receiver that moves synchronously in the same direction as the head, a tubular punch having an inner diameter in which the cutter is fitted to the cutter head is mounted so as to be able to move up and down, and the upper end of this punch is for sucking scraps. A punch receiving member is provided on the cutter receiver so as to face the lower side of the punch by connecting an intake device. Further, in the present invention, instead of connecting an intake device to the tubular punch, a punch receiving member of a cutter receiver provided below the tubular punch is provided with an air blowing hole facing the tubular punch and opening on the upper surface of the cutter. A compressed air supply device for blowing out scraps is connected to the air blowing hole.

[Action]

The cutting device for a laminate according to the present invention moves and stops the cutter head so that the tubular punch is positioned above the cutting start position of the laminate laminated on the support member, and lowers the punch to perform lamination. The product is penetrated and the tip (lower end) part of the punch is brought into contact with the punch receiving member to punch out the laminate and hold the scraps in the punch. After that, the punch is raised and returned, the cutter head is stopped by moving the cutter head to a position where the cutter faces the punching hole by the punch, the cutter is lowered and inserted into the punching hole, and the tip of the cutter is fitted into the cutter receiver. In this state, the cutter is moved in the same manner as the conventional one described above to start cutting the laminate. With this configuration, even when the thickness of the laminate is large when the cutter descends, the tip of the cutter can be easily brought into contact with the cutter receiver, and the cutter vertically penetrates the laminate without bending. Therefore, the laminate can be cut accurately without causing cutting deviation, and the tip of the cutter fits securely into the hole of the cutter receiver, and there is no positional deviation between them, which may damage the cutter. Nor. Then, the scraps held in the punch can be removed to the outside of the punch by driving the intake device after the punch is returned to the ascending state or by driving the compressed air supply device before the punch is raised. The punching operation of the laminate due to the next lowering of the punch can be reliably performed without any trouble.
