Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting device for cutting objects to be cut, and in particular,
This invention relates to a cutting apparatus suitable for automatically or semi-automatically cutting a plurality of stacked cloths.

[Prior art and its problems]

Conventionally, when cutting cloth according to a pattern, as shown in FIG. The marking sheet 1-3 on which type 2 was written was placed, and each city 1 was simultaneously cut along the outline of the marking sheet 3 using a manual cutting machine 4.

However, such conventional cutting methods have problems in that they are inefficient and require a lot of time because they are manual operations. Furthermore, in order to accurately cut the marking sheet 3 along the outline of the mold 2, a skilled technique is required, and if done manually, there is a problem that a deviation of about 2 to 3 mm may occur. Ta.

Furthermore, in recent years, automation has progressed in the industry where sewing machines are used, and sewing allowances and the like are automatically processed based on the cut surface, creating a demand for highly accurate cutting.

C) Object of the Invention The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a cutting device that can automatically and highly accurately cut objects to be cut, such as cloth.

(Summary of the invention) In order to achieve the above-mentioned object, a cutting device according to the present invention has the following features:
A cutting table on which an object to be cut is placed, a cutting manner in which the object to be cut is cut by being freely movable on the cutting table, and outlines of marking sheets 1 to 16 in which cutting shapes of the object to be cut are marked. A control device is provided that reads the line, and a control device that moves the cutting machine along the contour line of the marking seam type based on the detection signal from the sensor. Since the cutting machine is automatically moved along the outline of the marking sheet mold, it is possible to perform cutting work with high precision and in a short time without manual intervention.

(Example of the invention) The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a first embodiment of the present invention, and shows a cutting table 5 on which a plurality of pieces of cloth 1 are placed as an example of objects to be cut.
On both sides, both ends are upright portions 6a.

6b, a gate-shaped column 6 on which a beam portion 6C extending substantially horizontally is formed as a bridge is disposed so as to be able to reciprocate (in the direction of arrow X) along both side edges of the cutting table 5. , a holding member 7 is attached to one side edge of the beam portion 6C of the column 6 so as to be reciprocally movable (in the direction of arrow Y) along the beam portion 6C in a direction perpendicular to the moving direction of the column 6. There is.

On the lower surface side of the holding member 7, a cutting machine 9 having a cutting blade 8 attached to the lower end portion for cutting the cloth 1 is installed vertically, and the lower end of the cutting machine 9 near the cutting blade 8 The department includes
A sensor 10, which will be described later, is attached. Said column 6
, the holding member 7 and the cutting machine 9 are each driven by a drive motor (not shown) or the like so that the cutting pieces 19 can be freely moved on the cutting table 5. The member 7 is rotated (
(in the direction of arrow B), and the cutting blade 8 is always on the marking sheet 3.
The direction can be changed to follow the contour line of type 2.

The sensor 10 reads the outline of the mold 2 of the marking sheet 3 on which the mold 2 for cutting the cloth 1 is drawn, and outputs the read detection signal to a control device (not shown). The apparatus drives the column 6, the holding member 7, and the cutting machine 9 based on the detection signal of the sensor 10, so that the rF+19 cutting blade 8 moves along the outline of the marking sheet 3. It is designed to be controlled.

Next, the operation of the above-described embodiment will be explained.

In order to cut the cloth 1, the marking sheet 3 is placed on the top surface of a plurality of cloths 1 stacked on the cutting table 5, and the sensor 10 is activated to cut the marking sheet 3. The fabric 1 can be automatically cut by reading the contour line of the mold 2 and moving the cutting blade 8 of the cutting machine 9 along the contour line by the control device based on the read detection signal.

Therefore, in this embodiment, since the cloth 1 can be cut automatically, the cutting time can be shortened, and moreover, the cutting can be performed with high precision. Further, since the mold 2 of the marking sheet 3 is directly read by the sensor 10, there is no need to input data or create numerical data in advance using CAD for the cutting type, and the cutting can be easily and inexpensively performed.

FIG. 2 shows a second embodiment of the present invention. In addition to a cutting table 5 on which a plurality of fabrics 1 are placed, a reading table 11 on which only marking sheets 3 are placed is provided. As in the first embodiment described above, there is a gate-shaped column 6 that is movable along both side edges of the cutting table 5, and a gate-shaped column 6 that is movable along one side edge of this column 6 and that cuts on the bottom surface. The machine 9 has a holding member 7 rotatably mounted thereon. Further, a gate-shaped column 12 and a holding member 13 are similarly arranged on the reading table 11, and a sensor 10 for reading the outline of the mold 2 of the marking sheet 3 is attached to the holding member 13. ing. The control devices (not shown) of each column 6.12 are electrically connected to each other by cables 14, and are configured to move the cutting machine 9 of the cutting table 5 based on the detection signal of the sensor 10.

According to such a configuration, when the cloth 1 is placed on the cutting table 5 and the marking sheet 3 is placed on the upper surface of the reading table 11, and the sensor 10 is operated, the sensor 10 detects the marking sheet 3. Read the contour line of type 2,
Based on this detection signal, the control device controls the cutting machine 9 of the cutting table 5 via the cable 14 in the same manner as this contour line.
The cloth 1 can be cut by moving the cutting blade 8.

In this embodiment as well, as in the first embodiment described above, the marking of the cloth 1 can be done with high precision and in a short time according to the outline of the marking sheet 3. I! It becomes possible to perform lJ cutting.

[Effects of the Invention] As explained above, according to the present invention, it is possible to perform cutting work with high precision and in a short time without relying on manual labor.

Furthermore, since the type of the marking sheet is read by a sensor, there is no need to prepare data on the number of cutting types in advance, and cutting can be performed easily and inexpensively.
