BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth feeding device for a pattern sewing machine, and more particularly to a small and inexpensive cloth feeding device for a pattern sewing machine.

[0002]

2. Description of the Related Art FIG. 3 shows a pattern sewing machine.
The pattern sewing machine includes a sewing machine M and a cloth feeding device D that is installed on a sewing machine bed Ma of the sewing machine M and moves a workpiece (not shown) below the sewing needle N. The cloth feeder D includes a holding means 7 for holding the workpiece, a moving means C for moving the holding means 7, and a sewing table T for preventing the workpiece from swinging during sewing.

The moving means C comprises an X moving means 1 and a Y moving means 2. The X moving means 1 has an X rail 3 installed on the sewing machine bed Ma in the X direction, and is fitted to the X rail 3 X moving body 4 reciprocating in the direction
The moving means 2 includes a Y rail 5 installed on the X moving body 4 of the X moving means 1 in the Y direction, and a Y rail 5
And a support table 6 that reciprocates in the direction.

Although not shown, the moving means C includes a pulse motor, and the pulse motor can move the X moving body 4 and the support 6.

[0005] By the respective operations of the X moving means 1 and the Y moving means 2, the support table 6 moves the holding means 7 on the sewing machine bed Ma in the X direction, the Y direction, and the combined direction thereof, thereby enabling predetermined sewing. And On the other hand holding means 7
Is composed of a lower frame 8, an upper frame 9 provided to be able to move up and down with respect to the lower frame 8, and lifting means 10 for operating the upper frame 9. The lower frame 8 and the upper frame 9 are formed with through windows 7a as shown in the figure.

[0006] The holding means 7 lowers the upper frame 9 by the elevating means 10, holds (clamps) the material to be sewn between the upper frame 9 and the lower frame 8, and holds the material to be sewn in the through window 7a. The moving means C moves on the sewing table T together with the movement of the support base 6 so as to form a seam pattern of a predetermined shape.

The lower frame 8 and the upper frame 9 of the sewing means 7 can be replaced as appropriate according to the shape to be sewn, and the lower frame 8 and the upper frame 9 in which various through windows 7a are formed. Is prepared. On the other hand, the sewing table T has a flat surface that covers the moving range of the two frames 8, 9 of the holding means 7,
The lower frame 8 is fixed to the sewing machine bed Ma so as to be positioned below the lower frame 8, and prevents the frames 8, 9 and the workpiece from swinging due to the vertical movement of the sewing needle N and the vertical movement of the upper frame 9.
And it is arranged in contact with the sewing object.

[0008]

However, the above-mentioned conventional pattern sewing machine has the following problems. That is, the support table 6 is provided so as to be fitted to the Y rail 5 and reciprocate. However, in order to reciprocate the support table 6 without swinging, the support table 6 naturally has a predetermined length. Must be formed.

The sewing table T needs to be arranged at a position separated from the moving means C so as not to come into contact with the support table 6 by the support table 6 formed in the longitudinal direction in the Y direction. As a result, the sewing table T protrudes larger than the sewing machine as shown in the drawing, and the entire pattern sewing machine must be enlarged, and the lifting / lowering means 10 and the sewing machine M also need to be enlarged to correspond to the installation position of the sewing table T. As a result, there arises a problem that the cost of the pattern sewing machine is increased.

By the way, in order to solve such inconvenience, the support table 6 is moved at a position lower than the sewing table T as shown in FIG.
, The sewing table T is positioned inside the sewing machine M, the pattern sewing machine is reduced in size, and the lifting / lowering means 10 and the sewing machine M are reduced in size and cost.

However, in order to move the lower frame 8 on the sewing table as shown in FIG. 5, for example, as shown in FIG. Must be formed, and the strength of the lower frame 8 is not only weakened, but also the manufacturing cost is increased. When preparing a plurality of lower frames 8 for performing various pattern stitches, it is often inconvenient to store the lower frames 8 if the lower frames 8 have the bent portions as described above.

[0012]

SUMMARY OF THE INVENTION A cloth feeder for a pattern sewing machine according to the present invention is made to solve the above-mentioned conventional problem, and a lower frame mounting portion of a support base and a sewing table are arranged at substantially the same height. A retreat portion is formed at the upper end of the support table on the side of the sewing table to prevent contact between the end of the sewing table and the end of the support table.

[0013]

In the pattern sewing machine according to the present invention, the retreat portion is formed at the upper end of the support table on the side of the sewing table. Therefore, even if the support table moves in the direction of the sewing table, the retreat portion overlaps below the sewing table. Therefore, the support table does not come into contact with the sewing table.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The same or corresponding parts as those in the conventional example are denoted by the same reference numerals, and redundant description will be omitted. 1 and 2 are views showing one embodiment of a pattern sewing machine according to the present invention.

In FIG. 1, the support 6 of the moving means C is Y
The mounting surface 6a of the lower frame 8 is formed to have a necessary and sufficient length to move on the rail body 5 without swinging.
Is the same height as the upper surface of the sewing table T. The elevating means 10 and the lower frame 8 are installed on the upper surface 6a of the support 6 so as to move together with the support 6.

Reference numeral 6b denotes a retreating portion formed by cutting out the upper end of the support base 6 on the side of the sewing table T. The retreating portion 6b corresponds to the thickness of the sewing table T as shown in FIG. Having a depth of 6b1 and extending in the Y direction,
It is formed to have a width 6b2 that does not hinder installation of the lifting means 10 and the lower frame 8.

The sewing table T is installed inside the sewing machine by an amount corresponding to the width 6b2 of the retreating portion 6b as compared with the conventional pattern sewing machine, thereby making the pattern sewing machine overall smaller. Fig. 2
Even if the support table 4 is moved in the direction of the sewing table T as shown in (b), the retreat portion 6b enters below the sewing table T so as to overlap, so that the support table 4 and the sewing table T do not come into contact with each other. Absent.

The sewing table T and the support table 6 (upper surface 6)
Since a) is arranged at the same height, the lower frame 8 fixed to the support base 4 can be formed flat as shown in the figure.

[0019]

As described above, the cloth feeder of the pattern stitch sewing machine according to the present invention arranges the lower frame mounting portion of the support base and the sewing table at substantially the same height, and arranges the support table on the side of the sewing table. A retracting section is formed at the top of the tip to prevent the end of the sewing table from contacting with the end of the support table, so that the support table has the necessary length to reciprocate without swinging on the Y rail. Thus, the sewing table can be installed inside the sewing machine, and the size of the pattern sewing machine can be reduced.
