Description

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

[Prior art]

Conventionally, in sewing operations using industrial sewing machines, the current situation is that the finished sewing items are manually stacked on a mounting table from the sewing position.

[Summary of the Invention] This invention was made in order to omit the conventional manual work as described above. , the sewing products are stacked upside down on a mounting table, and then the mounting table is removed from the sewing position.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views showing an embodiment of the stacker device according to the present invention. In the figures, 1 indicates the sewing position of the sewing machine, and the stacker device is attached to the needle bar 2 linked to the upper shaft of the sewing machine. The needle 3, a presser foot (not shown), a lower press plate for holding the sewing object, and a mechanism (not shown) for moving these in a specific pattern in synchronization with the vertical movement of the needle are arranged.

Reference numeral 6 indicates a mounting table mechanism disposed on one side of the sewing position 1, which includes a guide section 8 fixed on a frame 7 protruding from the front part of the top plate 4, and a guide fixed on the upper surface of this guide section 8. a mounting table 11 having a mounting surface 10 movably attached to the guide rail 9 and disposed on one side of the sewing position 1 apart from the throat plate 5; It consists of a fixed cylinder 12. The piston 12a of this cylinder 12 is fixed to the mounting table 11.

Reference numeral 13 denotes a yoke end support section disposed below the sewing position 1, a presser bar 14 disposed at the lower front side of the throat plate 5 in correspondence with the end surface on the throat plate 5 side of the mounting base 11, and the top plate 4. Cylinder 1 fixed to the bottom of
It consists of 5. Piston 15 of this cylinder 15
A is fixed to the lower end of a swinging arm 17 connected to the top plate 4 by a pin 16. A swing arm 17 is fixed to the presser bar 14.

Reference numeral 18 indicates a yoke removal mechanism, and the guide portion 8
A slider 19 is rotatably mounted on a rail formed on the lower surface of the slider 19, and a bearing 20 is rotatably mounted on a bearing 20 extending from the rear end of the slider 19 to the rear upper part of the mounting surface 10 and arranged horizontally. Throat plate 5 of shaft 21
A blowing stick 22 fixed to the side protruding end, and this blowing stick 2
A piston 24a is connected to a swinging arm 23 fixed to a shaft 21 with a cylinder 24 fixed to a bracket 25 protruding from the lower rear surface of the bearing 20, and a cylinder 26 fixed to the lower surface of the top plate 4. It consists of Piston 2 of this cylinder 26
6a is fixed to a bracket 27 protruding from the lower surface of the slider 19. Each of the cylinders 12, 15, 24, and 26 is connected to an air compressor (not shown) via a control valve, and the switching operation of the control valve controls the supply and discharge of pressurized air from the air compressor. Each piston 12 in alternation
a, 15a, 24a, and 26a are adapted to perform expansion and retraction operations.

Next, the operation will be explained. When sewing a name member Y to a sewing product, for example, a yoke member
are arranged as shown in the first figure. That is, the mounting table 11 is arranged at a distance from one side of the throat plate 5, and the presser bar 14
is arranged below the throat plate 5, and the brushing rod 22 is placed below the throat plate 5.
and the presser bar 14. Then, one end of the yoke member X is suspended downward from one side end of the throat plate 5 and positioned between the mounting table 11 and the presser bar 14, and the name member Y is sewn onto the yoke member X. After this sewing work is completed, the piston 12a of the cylinder 12 is extended to move the mounting table 11 toward the throat plate 5, and the piston 15a of the cylinder 15 is moved to the side of the throat plate 5.
is retracted and the presser bar 14 is moved to the mounting table 11 side, so that one end of the yoke member By moving, the brushing rod 22 is caused to pass above the mounting surface 10 from the sewing position 1. As a result, the yoke member X is placed upside down on the mounting surface 10 with the name member Y facing downward as shown in the second figure. After that, the pistons 12a, 15 of the cylinders 12, 15
Operate a in the opposite direction to the above to remove the mounting table 11 and presser bar 1.
4 to the state shown in the first figure, and after extending the piston 24a of the cylinder 24 and rotating the blowing rod 22 downward, the piston 26 of the cylinder 26 is
By retracting a, the blowing rod 22 is placed on the mounting surface 1.
The throat plate 5 is spaced apart from the rear edge of the yoke member
Move to the side. Then, when the blowing rod 22 passes through the yoke member X and is positioned in front of the presser rod 14, the piston 24a of the cylinder 24 is retracted, the blowing rod 22 is rotated upward, and the piston of the cylinder 26 is moved upward. With the retraction of 26a, the gap between the needle plate 5 and the presser bar 14 is restored. Thereafter, place the next yoke member The members Y are turned over and stacked on the mounting surface 10, specifically, on the previous yoke member X, one after another.

〔Effect of the invention〕

As described above, according to the present invention, after sewing is completed, by supporting one end of the sewn items and sweeping the sewn items to one side from the sewing position, the sewn items can be stacked upside down on the mounting table. Moreover, since the mounting table can be separated from the sewing position, the sewing machine or the like does not get in the way when a sewing product is taken down from the mounting table, and the mounting table does not get in the way when the operator is sewing. Since the blowing stick does not pass over the stacked sewing items during recovery movement, the blowing stick does not hit the sewing items and damage or break them, and when the worker unloads the sewing items from the mounting table, does not hit the worker.
