Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a drafting table or a cutting table (hereinafter referred to as a cutting table) equipped with a head having a drawing instrument or a blade (hereinafter referred to collectively as a drawing instrument) that is relatively movable in the X and Y directions by numerical control means. The present invention relates to a means for transmitting operation production signals in an automatic drafting machine, which includes a drawing table (together referred to as a drafting table), an operating table for operating the drawing table, and a control device for controlling the drafting table.

The conventional transmission of operation control signals for a self-drawing machine will be explained using diagrams.

Fig. 1 is a perspective view showing the melting of a conventional automatic drafting machine, in which 1 is the drafting table main body, 2 is the Y rail, 3 is the head, 4 is the operating table,
5, 5' are operation panels, 6, 6' are cables, 7 is a control device 1i1j, 8.9 is a cable, and the drafting table main body 1. Y rail 2. The head 3 constitutes a drafting table lO.

At step A31, a drawing is made on the 18th side of the paper set on the drafting table 1 according to the command from the control device 7.

FIG. 2 is a block diagram showing a control signal transmission system of the automatic drafting machine, in which 70 is a magnetic tape device, and other symbols are the same as in FIG. 1.

The operating table 4 can be divided into those installed next to the drafting table and those installed separately from the drafting table, but in this description, it will be assumed that the operation table 4 is installed separately.

In addition, the control device 7 is built in the drafting table, and the control device 4 is built in the drawing table.
There are some built-in devices, but in this explanation they are placed separately.

Therefore, the magnetic tape device 70 for performing program drawing of the drawing machine is also built into the drawing table 10, and the operation table 4
In this explanation, in an automatic drawing machine installed in this way, the operator sets the paper 1a on the drawing table, and in order to draw the desired drawing, set the drawing starting point 1.
Guide the head 3 to point b, and set the drawing origin 31a of the drawing instrument 31 attached to the head 3 to the drawing starting point 1b on the paper la.
X to match.

It is necessary to align the axis in the Y direction and to make corrections due to the shrinkage of the paper 1a.

Operation panel 5. for axis alignment correction work. Or 5'(
It is necessary to operate the switches on the operation panel 5 (hereinafter referred to as operation panel 5), check and read on the drafting table, and then return to the operation panel 5 position to perform the next operation and repeat the operation to make corrections. This operation requires a great deal of effort and time to make corrections when the drafting table is large, which has the disadvantage of making the operation of the automatic drafting machine inefficient.

In order to solve this drawback, it was considered that the operation panel 5 could be removed from the drafting table, and when correction work was to be carried out, the operation panel 5 could be carried to the vicinity of the correction point on the drafting table, but the signal transmission However, the disadvantage remains that the length and weight of the cape tare 6 for movement to the correction point impairs operability. .

In addition, if the drafting table becomes large, it may be considered to divide the operation panel 5 into multiple operation panels 5 and 5', and at the same time, divide the cable 6 into cables 6 and 6', but this method would result in a complicated circuit. This results in other drawbacks, such as the need to add an ink clock device to prevent malfunctions even if they are operated at the same time.

The present invention has been made in order to eliminate the drawbacks as explained above, and this will be explained with the help of drawings. This is a perspective view showing the configuration, 40 is a control panel, 40a is a transmitting/receiving device for the control panel 40, 4, 1 is a control panel, 41a is a transmitting/receiving device for the control panel 41, and other symbols are the same as in FIG. 1. .

Figure 4 shows the control of the automatic drafting machine according to the embodiment shown in Figure 3.
+ In the block diagram showing the signal transmission system, 400 is infrared,
Indicates the propagation medium of ultrasound, radio waves, etc. Other symbols are the same as in FIG. 3.

In figure M3, the operation panel 40 has a portable housing structure,
A control signal from the operation panel 40 is transmitted from the transmitting/receiving device 40a to a transmission medium 400 such as infrared rays, ultrasonic waves, or radio waves, and the transmitting/receiving device 41a of the operating console 41 transmits the transmission medium 400.
0, the console 41 transmits the received control 111 signal to the control device R7, and the control device f#, 7
sends a predetermined control signal to the drafting table to move the head 31 to
Control movement on the Y axis.

Therefore, the operator can carry the operation panel 40 close to the point on the drafting table where correction work is to be performed, and immediately send subtle control signals to align the drawing origin 31a with the drawing start point 1b. , correction work can be easily performed without having to go back and forth to the fixed position of the operation panel 5 as shown in FIG.

Further, there is no need for the hassle of having to route the cable 6 shown in FIG. 16 to the point where the correction work is to be performed, and the labor and time required for the work can be reduced.

FIG. 5 is a perspective view showing the configuration of an automatic drafting machine according to another embodiment of the present invention, in which 71 is a control device, and 71a is a control device 7.
In the transmitting/receiving device No. 1, the ill sign is the same as that in FIG.

FIG. 6 is a block diagram showing a transmission system for control signals of the automatic drawing machine according to the embodiment shown in FIG. 5, and shows propagation media such as 4003 infrared light, ultrasonic waves, and radio waves. The numbers of the songs are the same as in FIG.

In FIG. 5, the control signal from the operation panel 40 is transmitted from the transmitter/receiver device fi40a through a transmission medium 400a such as infrared rays, ultrasonic waves, or radio waves, and the transmitter/receiver device 4 of the operation panel 41
1a, the transmitting/receiving device 71a of the restraint device 71 transmits the transmission medium 4.
00a, the operation console 41 and the control device 71 select necessary control signals respectively, and the control device F, 71 sends a predetermined control signal to the drafting table to control the head 31 in X, Y@ Move and place above.

In the case of FIG. 5, the cable 8 is omitted and the operation console 41
As in the case of FIG. 3, it is possible to install the device at any position and reduce the operator's work effort and time.

As yet another embodiment of the present invention, although not shown, a drafting table 1
A transmitting/receiving device is installed at the transmitting/receiving device 7 of the control device 71.
1a, the control signal is transmitted between the control device and the control device fPj70 via a transmission medium such as infrared rays, ultrasonic waves, or radio waves, so that the transmission cable 9 can be omitted. It is possible to eliminate restrictions on the installation position of a 71-stroke drafting table.

As explained above, according to the present invention, the operation panel 40. By installing the operator, it is possible for the operator to
The drawing starting point 1b, the drawing origin 31a, and the drawing starting point 1b at 3 degrees can save labor and time for positioning, and the operation table 41. Control device 71
．． This has great effects on the configuration of an automatic drafting machine, such as being able to eliminate restrictions on the installation position of the drafting table loquat.
