Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automatic sewing device for an industrial sewing machine.

[Prior art]

Conventionally, when sewing work using an industrial sewing machine, the series of operations such as feeding the sewing product to the sewing position of the sewing machine and removing the completed sewing product from the sewing position were performed manually. This is the current situation.

[Summary of the invention]

This invention was made in order to omit the conventional manual work as described above, and it automatically supplies the sewing product to the sewing position before the sewing machine starts sewing, and also automatically supplies the sewing product to the sewing position after the sewing machine finishes sewing. They are automatically removed from position and stacked.

9, 40, 41, 42, 43, 46, 48,
Piping is connected to an air compressor (not shown) via a control valve, and each piston rod is expanded and contracted by alternate operation of supplying and discharging pressurized air from the air compressor by switching operations from a control section E of the control valve. It's getting old. F indicates a sewing operation section of the sewing machine, and this sewing operation section F and the above-mentioned control section E are connected as will become clear in the operation described later.

Next, the operation will be explained. Before setting the yoke member X constituting one part of the sewing product and the name member Y constituting the other part of the sewing product in the loader device A, the base 14 is stopped at the setting position 15 as shown in the first figure. At the same time, each setter section 9,
9 and the free end of the name positioning part 10 are set surface 1
It is stopped at a distance above 6. Furthermore, the mounting table part 26 of the stacker device B is separated from one side of the throat plate 6,
The terminal support part 27 is stopped below the throat plate 6, and the brushing part 28 is stopped between the throat plate 6 and the terminal support part 27. Further, the needle 3 and presser foot 4 of the sewing machine are both stopped at the top dead center position. In this state, the operator places the yoke member X on the lower setting surface 16 of the yoke setter section 9 using a mark (not shown) as a reference, and then turns on a foot switch (not shown). As a result, the yoke cylinder 39 retracts, the yoke setter section 9 rotates downward about the hinge 17, and after the yoke member X is supported on the setting surface 16 by the yoke setter section 9, the positioning cylinder 4
1 retracts, the name positioning part 11 rotates downward about the hinge 22, and the name positioning recessed part 24 is placed at the set position on the yoke member X. Therefore, the operator places the name member Y on the yoke member X using the name positioning recess 24 as a guide, and then turns on the foot switch (not shown). This allows name cylinder 4
0 retracts and the name setter section 10 moves to the hinge 1.
9 as the center of rotation, and rotate the name member Y.
After holding down the base cylinder 38, the base cylinder 38 retracts and the base 14 of the loader device A is moved to the set position 15.
Immediately before the yoke member X and name member Y are pressed against the setting surface 16 and stopped at the sewing position 1, the presser foot 4 starts moving downward, Sewing position 1 on the above placement surface 16
After stopping at , the presser foot 4 presses down the name member Y and the yoke member X from both sides of the name setter section 10. Thereafter, the cylinders 39, 40, 41 are extended, and the setter parts 9, 10 and the name positioning part 11 are rotated upward, and both the members X,
After the pressure of Y is released, the base cylinder 38 is extended and the set surface 16 is pulled out from between the yoke member X and the throat plate 6 as shown in the second figure, and moves back to return to the set position and stop. At the same time, the sewing operation of the sewing machine starts. Then, the next yoke member
Press down with
When the base cylinder 38 of the loader device A retracts in response to the recovery completion signal No. 8, the base 14 moves forward, and the next yoke portion X and name member Y are transported to the sewing position 1 (see FIG. 2).

In response to the sewing completion signal of the yoke member At the same time, the terminal support section 27 moves to the mounting table section 26 side and presses one end of the yoke member X, and then the wiping cylinder 48 extends and the wiping slider 34 moves, and the wiping section 28 passes above the mounting surface 32 from the sewing position 1. As a result, after the yoke member At the same time as the terminal support section 27 is restored, the swinging cylinder 46 is extended and the discharging section 2
8 rotates downward, the brushing cylinder 48 retracts, and the brushing portion 28 moves toward the throat plate 6 while being separated from the rear edge of the yoke member X on the mounting surface 32. Then, when this sweeping part 28 is located after passing through the yoke member X and in front of the terminal support part 27,
The swing cylinder 46 retracts and returns to a position between the throat plate 6 and the terminal support portion 27. When this restoration is completed, a restoration completion signal of the removal section 28 of the stacker device B is supplied to the base cylinder 38 of the loader device A (see FIG. 3).

〔Effect of the invention〕

As described above, according to the present invention, the sewing product is automatically supplied to the sewing position before the sewing machine starts sewing, and the sewing product is automatically removed from the sewing position after the sewing machine finishes sewing, and the sewing product is automatically removed from the sewing position. Since they are stacked on top of each other, it is possible to automate a series of sewing operations in which the next sewing item is loaded into the loader device while the next sewing item is being sewn, and the completed sewing items are collected before setting the next sewing item. It is possible to achieve efficiency and shortening of sewing work.
