Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method in which numerical information on the shape of each of a large number of paper patterns is input into a computer (processing device) in advance in correspondence with symbol data of each paper pattern. When placing a large number of the above-mentioned paper patterns on the object to be cut to create a cutting trajectory pattern, and converting this pattern into digital information of numerical system,
Operate the coordinate analyzer to read the symbol data of each pattern to be read and the coordinate values of two preset positions on the pattern, enter these data into the above-mentioned computer, and from the computer read the pattern data. The present invention relates to a method for converting cutting locus patterns into numerical information, characterized in that a digital information output for numerical control is obtained.

The configuration of the present invention will be described in detail below with reference to the accompanying drawings.

1 is a coordinate analysis machine, and an X rail 2 supported on a mount,
X cursors 4 and 5 are slidably attached to the X cursors 3, and a Y cursor 7 is slidably attached to the Y rail 6 installed between the X cursors 4 and 5.

A reading head 8 having a crosshair indicator drawn on a transparent body is attached to the Y cursor 7.

X rail 2 of the X cursors 4, 5 and Y cursor 7,
The movement along the Y rails 3 and 6 is converted into pulses by an encoder, and the number of pulses is counted and displayed by a counter 9.

10 is a keyboard, which is connected to the input/output device 11;

Reference numeral 12 denotes an object to be cut, and on the object to be cut 13 made of a plastic plate, cloth, or other sheet-like member supported by this means, a large number of paper patterns 14 are placed by the means. A cutting locus pattern is formed on the object 13.

The object-to-be-cut support means 12 is placed on a carrier (not shown).

A computer (processing device) 15 is connected to a control section of an automatic cutting machine 18 via an interface 16 and a console 17.

Digital information about the shape of each of a large number of patterns 14 is input into the storage device of the computer 15 for each pattern symbol code.

19 is a tape reader of the computer 15;

The interface 16 is a processing device (computer) 15
The computer is connected to the numerically controlled automatic cutting machine 18 to smoothly exchange information, and it relays commands from the console 17 and controls the input and output of the automatic cutting machine 18 and computer 15.

The operation console 17 is used to issue instructions to the automatic cutting machine 18, including starting and stopping the machine.

In the above-described configuration, the carrier is moved and the supporting means 12
was brought between the X rails 2 and 3, and positioned at a predetermined position.

Next, two preset points a on the object to be cut 13 are set.

Position the index of the reading head 8 at each of b,
Read the X-Y coordinate values of the two points a and b, and press keyboard 1.
0, the X-Y coordinate values are punched into the tape 22, and the position of the object 13 to be cut is input into the tape 22 as numerical information.

Next, the symbol data of the paper pattern 14 to be read, for example coded numerical information of AI, is perforated on the tape 22, and the two preset points a' of the paper pattern 14 are punched.

The X-Y coordinate values of the position b' are read and the tape 22 is punched with these values.

In this way, the symbol-encoded numerical information of the paper pattern 14 and the positional numerical information of the paper pattern are punched into the tape 22 one after another.

Next, the object supporting means 12 is brought to the cutting position of the automatic cutting machine, and then the tape 22 is applied to the tape leader 19 of the processing device 15.

The processing device 15 internally processes these numerical information according to a program based on the numerical information of the tape 19 and the numerical information of a large number of paper patterns inputted in advance, and creates numerical control information of the cutting trajectory pattern. .

This numerical control information is supplied to the control section of the automatic cutting machine 18.

The automatic cutting machine 18 is driven by digital information signals from the computer 15, and cuts the object 13 supported by the object supporting means 12 along a cutting locus pattern.

In this embodiment, the cutting locus pattern was formed by placing a large number of actual-sized paper patterns 14 directly on the object to be cut 13, but the reduced pattern was placed on a reduced model of the object to be cut. Alternatively, a cutting locus pattern may be created and read.

Further, the coordinate analyzer 1 may be connected to the computer 15 online.

As described above, the present invention inputs numerical information on the shapes of a plurality of paper patterns into the processing device in advance.
By simply reading the coordinate values of the point positions one after another and inputting this numerical information into the processing device, numerical control information for the cutting locus pattern can be obtained, making the work of reading the coordinates of the cutting locus pattern extremely simple, quick and efficient. There are some effects that can be achieved.
