[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for holding a workpiece to be transported, in which a holding frame for holding the workpiece is transferred in a direction perpendicular to the vertical movement direction of the needle of the sewing machine.

[0002]

2. Description of the Related Art Conventionally, this kind of a device for holding a sewing object has
For example, there is a holding device for an embroidery sewing machine. A schematic configuration of the holding device of the embroidery sewing machine will be described with reference to FIG.

A sewing machine bed 51 protrudes from a sewing machine table (not shown). Further, a Y-direction feeding device 53 is provided on the sewing machine table so as to be movable in the Y direction which is the longitudinal direction of the bed 51. The Y-direction feeder 53 includes a rail 55 extending in the X direction orthogonal to the Y direction and a slider 5 slidable on the rail 55.
7 are provided. The slider 57 has a frame holder 5
9 is fixed by screws 61a and 61b. An embroidery frame 63 on which a sewing object is stretched is mounted on the frame holder 59 in parallel with a gap of about 1 mm to 1.5 mm with respect to the surface of the sewing machine bed 51. It can move in the X direction and the Y direction orthogonal to the vertical movement direction.

[0004]

However, in the above-described embroidery sewing machine holding device, since the slider 57 supports the weight of the frame holder 59 and the embroidery frame 63, the heavy sewn material is not embroidered by the embroidery frame. The embroidery frame 63 is no longer parallel to the bed 1 when the embroidery frame 63 is attached to the bed or when a large embroidery frame is attached. That is, the embroidery frame 63 on the right side in FIG.
The worker side may be lowered and the sewing object may come into contact with the bed 51 surface. When there is no gap between the sewn material and the bed 51 surface, the bed 51 surface and the sewn material are rubbed, so that when the upper thread is tightened by a balance (not shown), a frictional force is applied to the upper thread and the lower thread, The seam tightens poorly. If there is a gap, no friction is applied to the upper thread and the lower thread, so that tightness is good. Therefore, in the case described above, there is a problem that a portion having poor tightening and a portion having good tightening are formed in a sewing pattern of one piece of the sewing object, and the quality of a sewn product is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to maintain a constant gap between a workpiece and a bed surface to hold the workpiece. An object of the present invention is to provide a holding device for a sewn product.

[0006]

In order to achieve this object, a holding device for a sewn object according to the present invention includes a holding frame for holding a sewn object, and a needle for vertically moving the holding frame on a sewing machine bed surface. A feeding device for transferring the holding frame in a direction perpendicular to the direction, and mounting means for adjusting the holding frame so as to be parallel to the sewing machine bed surface .

[0007]

The feeder of the device for holding a sewn object of the present invention having the above-described structure transfers the holding frame for holding the sewn object in a direction perpendicular to the vertical movement direction of the needle of the sewing machine. Then, parallel the holding frame for the sewing machine bed surface by attachment means
And attached to the feeder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in an embroidery frame holding device of an embroidery sewing machine will be described with reference to the drawings.

A sewing machine bed 1 protrudes from a sewing machine table (not shown). The sewing machine table is provided with a Y-direction feeder 3 that is movable in the Y direction, which is the longitudinal direction of the bed 1. As shown in FIG. 1, the Y-direction feeder 3 includes a rail 5 extending in the X direction perpendicular to the Y direction, and a slider 7 slidable on the rail 5.

As shown in FIGS. 2 and 3, the slider 7 has a positioning plate 11a on which positioning pins 9 are projected.
11b is fixed. When the positioning pins 9 are inserted, the tilt adjusting plates 13a and 13b are moved to the positioning plates 11a and 1b.
1b.

The frame holder 15 is rotatably supported on the tilt adjusting plates 13a and 13b by stepped screws 17a and 17b. Further, tilt adjusting bolts 21 a and 21 b having a thread portion longer than the screw holes 19 a and 19 b are screwed into the screw holes 19 a and 19 b of the frame holder 15, and the tips of the bolts 21 a and 21 b are inserted into the tilt adjusting plate 13. The frame holder 15 is supported in contact with the frame holder 15. Then, the inclination adjusting plates 13a, 13b pass through the through holes 23a, 23b of the frame holder 15.
Screw 25a, 25b into the frame holder 15
The rotation of is fixed.

The embroidery frame 27 has an embroidery frame mounting bracket 29a,
29b is fixed. The mounting brackets 29a and 29b are fixed to the frame holder 15 by embroidery frame mounting screws 31a and 31b, respectively. The embroidery frame 27 thus attached is movable in the X direction and the Y direction orthogonal to the vertical movement direction of the sewing needle 33, and is rotatable around the axes of the stepped screws 17a and 17b. is there.

In order to attach the work cloth to the embroidery frame holding device, first, the work cloth is put on the embroidery frame 27, and the embroidery frame 27 is attached to the frame holder 15 via the embroidery frame mounting brackets 29a and 29b.
Are fixed with embroidery frame mounting screws 31a and 31b. Due to the weight of the frame holder 15 due to the weight of the work cloth and the embroidery frame 27, the worker side, which is the tip side of the bed 1 on the right side in FIG. 1, is lowered, and the sewing surface of the work cloth comes into contact with the bed 1 surface. Then, tightening screw 25a,
The frame holder 15 is rotated about the axis of the stepped screws 17a and 17b by loosening the 25b and then screwing the tilt adjusting bolts 21a and 21b. The tilt adjusting bolts 21a and 21b are adjusted so that one bed and the embroidery frame 27 have a clearance of about 1 mm to 1.5 mm and are kept parallel. Then, the frame holder 15 is fixed to the slider 7 of the Y-direction feeding device 3 with the tightening screws 25a and 25b.

As described above, the embroidery frame 27 can be adjusted so as to be parallel to the one bed, so that the clearance between the sewing surface of the work cloth and the one bed is constant. Therefore, there are no poorly-sealed portions and tightly-sealed portions in the sewing pattern of one work cloth, and the quality of the sewn product is not deteriorated. Good quality.

In this embodiment, the frame holder 15 is rotatably supported by the slider 7, but may be arranged as follows. That is, the frame holder 15 is fixed to the slider 7, and FIG.
As shown in the figure, the embroidery frame 27 is attached to the embroidery frame mounting brackets 29a, 2b.
9b (only the embroidery frame mounting bracket 29b side is shown in FIG. 4) by stepped screws 41a and 41b (only the stepped screw 41b is shown in FIG. 4) so as to be rotatable. And screw 4
3a and 43b (only the screw 43b is shown in FIG. 4) are provided with holes 45a and 45 provided in the embroidery frame mounting brackets 29a and 29b.
b (only the hole 45b is shown in FIG. 4).
And the rotation of the embroidery frame 27 is fixed. In addition, various changes can be made in the present invention without departing from the gist thereof.

[0016]

[Effect of the invention] As is clear from the above description,
According to the present invention, the holding frame for holding the workpiece can be adjusted so as to be parallel to the bed surface, so that the clearance between the sewing surface of the workpiece and the bed surface is constant, and one sewing In the sewing pattern of the product, there are no poorly tightened portions and well-tightened portions, and the quality of the sewn product is not degraded. .
