Is deformed so as to hang down on the top plate (11) of the mounting table (10), so that the position of the welding point (P) is misaligned, and a uniform and highly accurate welding state cannot be always secured.

As the cloth holder (17), it is preferable to prepare at least two pieces of the welding point indicating holes (87) which are engraved (perforated). that way,
One of them is attached to the vertical / horizontal positioning arm (69), and while the cut fabrics (M1) and (M2) are being welded together, the next cut fabric (M1) is attached to the remaining fabric holder (17). (M2) It is because the competitors can be placed one on top of the other, and the manual work for the preparation can be easily performed by one worker. This includes a dough holder (1
It can be said that it is useful to be able to attach and detach 7) to both chuck claws (72) and (73) of the vertical and horizontal positioning arm (69) by stepping on the foot switch (FSW1).

Further, the air cylinder (21) for raising and lowering the engraving machine is provided with a rotary drill ascending position detecting sensor (S).
The lifting cylinder is controlled by the output signal from the lowering position detecting sensor (S4) and the lowering position detecting sensor (S4). Since the lifting and lowering is controlled by an output signal from the position detection sensor (S10), the rotary drill (2) of the die engraving machine (B) is used.
Even in the work of engraving (perforating) the cloth holder (17) according to 5), the welding point indicating holes (87) can be correctly distributed in the cloth holder without fear of damaging the synthetic resin cloth holder (17). .

When the cut fabrics (M1) and (M2) have different outline shapes and / or sizes and the target welding point (P) changes, the cut fabric (M
1) Prepare various cloth holders (17) engraved according to (M2), replace them with the vertical and horizontal positioning arms (69), use them, and cut the cloths (M1) (M2). It is needless to say that the automatic welding device of the present invention can be used for general purposes by storing the corrected graphic data in the memory (84) of the microcomputer as each corrected graphic data.

[0072]

As described above, as a method for automatically welding ladies' brassieres, slips, and other various cut fabrics according to the present invention, a fabric used by switching with a die engraving / welding work mode switch (SW) is used. The die engraving machine for holder (B) and the ultrasonic welding machine for cut cloth (W) are installed so as to face the top plate (11) of the installation table (10),

The above-mentioned top plate (11) is obtained by inputting a target welding point (P) which is scattered and distributed along the peripheral edge of the cut fabrics (M1) and (M2) to be welded, and teaching input of the welding point (P). The movement of the vertical / horizontal positioning arm (69) for the cloth holder, which is moved vertically and horizontally, is stored as graphic data in advance in the memory (84) of the microcomputer.

First, the changeover switch (SW) is set to the engraving work mode, and the vertical and horizontal positioning arms (6) are set.
9) A cloth holder (17) capable of sandwiching the cut cloths (M1) and (M2) is attached to the cut cloth (M1) and (M2), and the vertical and horizontal positioning arms (69) are controlled to move based on the read signal of the graphic data. (B) is operated, and a welding point indicating hole (87) corresponding to the welding point (P) is die-cut into the dough holder (17) by the rotary drill (25) of the die-sculpting machine (B). And

Next, the changeover switch (SW) is switched to the welding operation mode, and the cut doughs (M1) and (M2) are placed one on top of the other at the predetermined position of the engraved dough holder (17). Dough holder (17)
Is mounted on the vertical and horizontal positioning arm (69) again, and also the movement control of the vertical and horizontal positioning arm (69) is reproduced based on the readout signal of the graphic data, and the operation of the welding machine (W) is controlled so that the dough holder is moved. Since the cut fabrics (M1) and (M2) are welded to each other by the tool horn (31) of the welding machine (W) entering the welding point indicating hole (87) of (17), it is described at the beginning. The problem of the prior art can be drastically solved, and there is an effect that a uniform and high quality temporary fixing state can be always obtained, and the mass productivity is also remarkably excellent.

That is, the welding points (P) scattered and distributed along the peripheral edge of the cut fabrics (M1) and (M2) to be welded, and the movement of the vertical and horizontal positioning arms (69) for the fabric holder following this. As long as it is stored in advance in the memory (84) of the microcomputer as graphic data, a welding point indicating hole (87) corresponding to the welding point (P) is inserted into the cloth holder (17).
The die-cutting (perforation) can be accurately performed by itself, and thereafter, only the welding operation of the same cut cloth (M1) (M2) may be repeatedly performed using the die-cut cloth holder (17). Anyone can efficiently process the large amount of cut fabrics (M1) and (M2).

This effect can be obtained by preparing a plurality of the engraved cloth holders (17).
It can be further improved. Also, cut fabric (M1)
(M2) Various cloth holders engraved according to the cut cloths (M1) and (M2) even when the target welding point (P) changes due to differences in the outline shape and size of the comrades. After preparing (17), this can be attached and detachably and exchangeably mounted on the vertical and horizontal positioning arm (69), and this is extremely convenient.

Further, since the automatic welding apparatus used for carrying out the above method employs the structure described in claim 2,
By using the one device, it is only necessary to switch between the engraving operation mode and the welding operation mode by operating the die engraving / welding operation mode switch (SW), so that the cost of the above device can be reduced and anyone can use it. There is an effect that can be used well.

In particular, if the structure of claim 3 is adopted,
When the tool horn (31) and the horn receiver (49) of the ultrasonic welding machine (W) correspond to and are aligned on the same vertical line (OO) passing through one selective escape hole (33). In combination with the vertical entry into the welding point indicating hole (87) of the cloth holder (17), the effect of always obtaining a very uniform and highly accurate welding state between the cut cloths (M1) and (M2) is obtained. is there.

If the structure of claim 4 is adopted, the cloth holder (17) required every time the target welding point (P) in the cut cloth (M1) (M2) changes.
Can be prepared relatively inexpensively, and based on the provided instruction mark (79), the cut fabric (M
1) Since (M2) can always be correctly placed and set at a predetermined position, and can be inspected through a perspective, the convenience in use is remarkably excellent.
