At this sewing position, when sewing by the sewing machine head 5 is completed in accordance with the sewing program, a drive command signal is output to the thread cutting mechanism 206 and the drive circuits 225 and 228 of the sewing machine motor 205 for thread cutting, The thread cutting operation is started (S1).

Next, when it is determined that the thread cutting operation is completed based on the detection result of the encoder 210, a drive command signal is sent to the drive circuits 123 and 327 for extending the cylinders 60 and 310. Is output. Then,
The body cloth W is firmly held in two places by the moving roller 55, the cloth pressing rubber 340 and the upper surface of the table 4 (S2). The drive command signal of S2 is the drive circuit 123.
When a certain time has elapsed after being output to 327, a drive command signal is output to the drive circuit 228 of the sewing machine motor 205 in order to position the sewing needle 9 at the uppermost point. Then, the sewing needle 9
Is separated from the body cloth W (S3). Next, presser bar 2
In order to raise 00, a drive command signal is output to the drive circuit 222 of the vertical movement mechanism 204, and the presser foot 202 separates from the body cloth W (S4). Further, in order to position the feed plate 11 at the uppermost point, the drive command signal is applied to the clamp mechanism 2.
It is output to the drive circuit 226 of 14 and the feed plate 11 is slightly separated from the body cloth W (S5).

Next, the drive command signal of S5 is the drive circuit 22.
When a predetermined time has elapsed after being output to 6, it is determined that the feed plate 11 has been separated upward from the body cloth W, and subsequently, the drive command signal moves horizontally to move the feed plate 11 from the sewing position to the preparation position. It is output to the drive circuit 224 of the mechanism 212, and the next body cloth W can be prepared by the folding machine 3 (S6). It should be noted that the fixed time for performing such processing is measured by the timer function of the CPU 100.

While the feed plate 11 is moved, the body cloth W is held between the moving roller 55 and the cloth pressing rubber 340 of the pad screw 320 and the upper surface of the table 4, so that the body cloth W is subordinate to the feed plate 11. Movement is restricted.

When the drive command signal of S6 is output to the drive circuit 224 and a certain period of time elapses, it is determined that the feed plate 11 is separated from the body cloth W in the horizontal direction, and subsequently the regulation air cylinder 310 is put into the retracted state. Therefore, the drive command signal is output to the drive circuit 327 of the electromagnetic switching valve 317, and the holding of the body cloth W by the cloth pressing rubber 340 of the pad screw 320 is released (S7).

When the drive command signal of S7 is output to the drive circuit 327 and a certain period of time elapses, it is determined that the cloth pressing rubber 340 of the pad screw 320 has separated from the body cloth W,
Subsequently, in order to put the air cylinder 56 into the retracted state, a drive command signal is output to the drive circuit 121 of the electromagnetic switching valve 111, and the movement of the body cloth W by the rotation of the moving roller 55 is started. When the body cloth W is moved forward by the rotation of the transfer roller 55, the whole body cloth W is located near the end of the loading platform 80, and the portion of the body cloth W hanging down from the front end of the table 4 is appropriately lengthened. Therefore, by lengthening the hanging portion of the body cloth W to some extent, the loading balance when the body cloth W is loaded on the loading platform 80 can be improved. The position where the sewing is finished is a movement start position where the movement of the work cloth W can be started by the moving mechanism 51, and the position of the work cloth W sent by the moving roller 55 is started by the loading mechanism 52 to load the work cloth W. This is a possible loading start position.

Next, as shown in FIG. 12, the piston rod 87 of the air cylinder 86 is advanced, the loading platform 80 is tilted to the table 4 side as described above, and the body is placed between the table 4 and the loading platform 80. Insert the hanging part of the dough W. At the same time, the cloth presser 91 tilts toward the table 4 side at the same time in synchronization with the loading table 80. At this time, in the moving mechanism 51, the piston rod 61 of the air cylinder 60 is advanced, the moving mechanism main body MP is swung upward, the transfer roller 55 is raised, and the body cloth W is released from the pressed state.

Next, the piston rod 98 of the air cylinder 97 of the loading mechanism 52 is advanced, and the cloth wiper 95 waiting on the lower side of the front end portion of the table 4 is turned to the front while the hanging portion of the body cloth W is hooked. Be moved. Therefore, the body cloth W on the table 4 is loaded on the loading platform 80 so as to be shaken off by the forward rotation of the cloth wiper 95.

On the other hand, at the same time, the piston rod 90 of the air cylinder 89 is retracted, and the presser foot 91 which is in contact with the loading platform 80 is rotated to the position shown in FIG. Immediately thereafter, the piston rod 90 of the air cylinder 89 is advanced, the cloth presser 91 is rotated upward again, and the loading platform 8 is moved.
This body cloth W loaded on 0 is pressed from the front.

Further, the piston rod 98 of the air cylinder 97 is retracted, the cloth wiper 95 is again rotated upward and returned to the lower position of the front end portion of the table 4, and the piston of the air cylinder 86 is further rotated. The rod 87 is retracted, and the loading platform 80 is returned and rotated to the standby position shown in FIG. In this way, every time the sewing of the pocket cloth piece P on the body cloth W is completed, the body cloth W on the table 4 is moved to the position corresponding to the loading platform 80 by the moving mechanism 51 and the loading platform is also loaded. The sheets are sequentially loaded on the 80 (S8).

Therefore, as the feed plate 11 moves in S6, the dependent movement of the body cloth W due to being caught on the feed plate 11 or its sponge S is restricted, and the body cloth W is always fixed after the end of sewing. Since the body cloth W is located at the position (moving start position) and can be favorably moved to the loading start position, the body cloth W is stably loaded on the loading table 80 in S8, and the body cloth W is The body cloth W is prevented from collapsing from the loading platform 80, and the body fabric W is loaded onto the loading platform 80 without protruding from the loading platform 80, and the body fabric W is prevented from interfering with the sewing operation. Further, since the work cloth W is stably loaded on the loading platform 80 in a stable manner, the time and effort for reloading the work cloth W on the loading platform 80 is reduced.

Further, since the work cloths W are all loaded on the loading table 80 and are easy to hold, and the work cloths W can be easily moved from the loading table 80 to another place, the working efficiency is improved. In the case of moving the work cloth W in the direction of the arrow Y orthogonal to the direction of the arrow X in the moving direction of the feed arm 10, the work cloth W is most likely to be moved (shifted). It is most necessary to regulate the movement of the work cloth W.

Since the movable roller 55 and the cloth pressing rubber 340 of the pad screw 320 are clamped at two places, the work cloth W is clamped more firmly than when clamped at one place. As shown, the body cloth W is prevented from rising together with the feed plate 11 due to static electricity or the like and shifting. Since the straight line connecting the two holding points extends in a direction substantially orthogonal to the moving direction of the feed plate 11,
The body cloth W can be firmly held. Furthermore, FIG.
Since the process of the flowchart shown in FIG. 14 is mainly performed with the passage of time, it is possible to arbitrarily set the time according to various work cloths W, and it is easy to try to approach the best work efficiency. is there.

It is needless to say that the present invention can be applied to various work cloth loading devices provided with the moving mechanism 51 and the loading mechanism 52.

The restricting means of the present invention such as the restricting cylinder 310 may be provided, for example, by hanging it from the ceiling or other stand other than the sewing device 2. In this case, the area of the table 4 is increased to facilitate the sewing work and reduce the load when the sewing machine head 5 is moved. Moreover, although the movement of the work cloth W is regulated by being sandwiched, the work cloth W is sucked,
The movement of the work cloth W may be restricted. If the regulation is performed by suction, even if the work cloth W is made of a slippery material, the dependent movement (deviation) can be reliably regulated. Further, although the process of the flowchart shown in FIG. 14 mainly proceeded with the passage of time, a sensor for detecting the position of the work cloth W, the feed plate 11 or the like is provided, and based on the detection result, You may proceed. When the position is detected, it is possible to control the work cloth loading device 50 more reliably than loading the work cloth only at the timing.

When the work cloth W is not moved by the moving mechanism 51 and the work cloth W is directly loaded on the loading table 80 from the position where the loading mechanism 52 finishes sewing, the control device 35 is used.
0 ··· Cloth cleaning 95 · Air cylinder 97 · Air cylinder 5
6, the moving roller 55 and the like correspond to the workpiece moving means according to the first aspect, and the loading start position is the position where the sewing is finished. In this case, the movement of the work cloth W can be similarly regulated by the regulation mechanism 300 at the loading start position.
The positional deviation of the work cloth W with respect to the work cloth W is prevented, and the work cloth W is stably loaded on the loading platform 80, or the work cloth W is loaded without protruding from the loading platform 80, which hinders the sewing operation. To be prevented. Further, the workpiece W is not largely displaced by the regulation mechanism 300, and the stacking mechanism 52 does not move the workpiece W.
Can be loaded reliably.

Further, when the regulating air cylinder 310 is installed below the arm portion 6 and the distance between the nipping point by the moving roller 55 and the nipping point by the material pressing rubber 340 is widened, the work cloth W is more firmly nipped. It is possible. Then, in the present embodiment, the pressing plate 11 moves in the direction of the arrow X,
The same effect can be obtained when moving in the Y direction.
