Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loader device for an industrial sewing machine, and more particularly to a mechanism for adjusting the setting position of a sewing product.

[Prior art]

Conventionally, the loader device of an industrial sewing machine is provided with a slider mechanism having a set surface that reciprocates between a sewing position and a set position in front of the sewing position. Some devices are provided with a setter section that presses the sewn product placed thereon, and a positioning section that indicates the position at which the sewn product is placed on the setting surface.

However, with this structure, the positioning section is fixedly attached to the setting surface, so the index position cannot be changed, and the loader device with a different positioning section must be assembled each time the sewing operation is changed. It was a hassle to replace the sewing work.

[Summary of the invention]

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional sewing machine, and aims to improve the efficiency of changing sewing operations by adjusting the movement of the positioning section relative to the setting surface of the slider mechanism.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a perspective view showing an embodiment of the loader device according to the present invention, and in the figure, 1 indicates the sewing position of the sewing machine;
Needle 3 attached to needle bar 2 linked to the upper shaft of the sewing machine
, a presser foot 4 that moves up and down along the needle bar 2, and a needle that is attached to a bed 5 and that holds the sewing material between the presser foot 4 and moves in a specific pattern in synchronization with the rotation of the sewing machine. A plate 6 is arranged. 7 indicates a set position set in front of the above-mentioned sewing position], and a guide rail 8 is installed between this set position 7 and the sewing position l, and this guide rail 8
A slider mechanism 9 is disposed in such a manner that it can freely reciprocate. The bracket 9a of this slider mechanism 9 has a set surface 10 arranged horizontally above the guide rail 8, and a slide cylinder with a cylinder tube supported on a bracket 11 fixed to the mounting base end side of the guide rail 8. The tip of piston rond 12 is attached. A pair of left and right yoke setter portions 13 that support a yoke member
The base end of the yoke setter part 13 is rotatably mounted via a hinge 14, and the free end of this yoke setter part 13 is formed from the base end to the setting surface 10 side. The tip of the piston rod of the yoke cylinder 15 with the cylinder tube attached to the mechanism 9 is fixed by passing through the set surface 10. The above pair of yoke setter parts 13
The base end of a name setter part 16 that supports the other name member Y constituting the other part of the sewn product is rotatably attached to the extended part located inside one of the parts, via a hinge 17.
The free end of this name setter section 16 is connected from the base end to the setting surface 1.
A step is formed on the o side, and the piston rond tip of a name cylinder 18 having a cylinder tube attached to the slider mechanism 9 is fixed to the base end side of the name section 16 by passing through the set surface 10. Reference numeral 19 indicates a name positioning portion, the base end of which will be described later.
9 via a hinge 20, and the free end passes through an escape recess 21 cut out inside the name setter part 16 of the slider mechanism 9, and the set surface 10 and the free end of the name setter part 16 are connected to each other. A positioning recess 22 is formed in an L-shape at one corner of the extending end.

The base 24 fixed on the upper surface in front of position 7 and this base 2
A movable base 26 is attached to a guide rail 25 horizontally mounted on a guide rail 25 so as to be movable in the left-right direction. An operation knob 27 screwed into the end wall, a support part 29 rotatably attached to the rear end of the moving table 26 via a hinge 28, and a tip end rotatably attached to the support part 29. It consists of a handle 32 that is threadedly fitted to the front end of a threaded rod 31 that passes through a rising wall 30 at the front end of the moving platform 26 that corresponds to the support section 29 . A spring 33 is provided on the outer periphery of the threaded rod 31 between the support portion 29 and the rising wall 30.
It is equipped with. Note that 34 is a spring disposed between the other end of the moving table 26 and the corresponding other end of the base 24.

Next, the operation will be explained. The yoke setter section 13, name setter section 16, and positioning section 19 are placed on the setting surface 10.
After rotating the yoke member X upward and placing the yoke member X on the setting surface 10 with reference to a mark (not shown) set on the setting surface 10, the yoke setter section 13 is moved by the retraction movement of the piston rond of the yoke cylinder 15. It rotates downward to support the yoke member X between the set surface 10 and the yoke setter section 13. Next, the positioning part 19 is rotated downward, the setting position of the name member Y is set on the yoke member X using the positioning recessed part 22, and the name member Y is set on the yoke member After being placed on top, the name section 19 is rotated downward by the retracting action of the piston rond of the name cylinder 18 to press down the name member Y.

Thereafter, the slide cylinder 12 is retracted to move the slider mechanism 9 together with both setter parts 13 and 16 to the set position 7.
The yoke member
After the yoke member X and the name member Y are pressed down to both sides of the yoke member
3 and name section 16 upward, and the slider mechanism 9 is moved back while pulling out the set surface 10 from between the yoke member X and the throat plate 6 by the extension action of the piston rond of the slide cylinder 12. Restores to set position 7.

Now, when sewing the name member Y to the yoke member X, when changing the position or sewing another name member to another yoke member, rotate the operation knob 27 in the direction of the arrow. As a result, the positioning recess 22 is moved and adjusted in the left-right direction via the moving table 26. Further, by rotating the handle 32 in the direction of the arrow, the positioning recessed part 22 is adjusted to move in the front-rear direction via the support part 29.

〔Effect of the invention〕

As described above, according to the present invention, the positioning section can be adjusted by moving forward, backward, left, and right with respect to the set surface of the slider mechanism, so that sewing one workpiece to another workpiece can be done by changing the position or When changing sewing operations such as changing the type of sewing, a new set position can be set without replacing the loader device, and the efficiency of changing sewing operations can be improved.
