(A) DEVICE FOR AUTOMATIC ROTATION OF PARTS WITH REGARD TO THE NEEDLE OF THE SEWING MACHINE

  , .

The invention relates to a sewing machine industry, namely to devices for automatically rotating parts relative to a sewing machine.

According to the main author. St. No. 751858 a device is known for automating the rotation of parts relative to the needle of a sewing machine, including two pairs of irreversible rings-) manipulators, which by means of two, hydraulic motors and di (| x1) gearbox f 1.

The known device is inefficient.

The purpose of the invention is to increase productivity.

The goal is achieved in that the device has two guide rollers for contacting each one of the parts to be machined, mounted on the sewing machine foot by means of spring-loaded brackets, and two stops for the parts, one of which is mounted on one of the.

driving rings, and the other on the axis of one of the guide rollers.

FIG. 1 shows the device, “general view; Fig. 2 shows the arrangement of the guides of the rollers relative to the needle of the sewing machine.

The device contains a roller 1 of the sewing head 2, the brackets 3 of the guide rollers 1. The machined parts 5 have an upper stop 6 and a LOWER stop 7. The manipulator rings (not shown) are placed on the bracket 8 and placed in the case 9 The brackets 3 are spring-loaded with a spring 10

The device works as follows $ 1 at a time.

At. transporting the material of the part 5 by a rack and pinion mechanism, the roller 1 of the tab rises according to the cyclogram, lifting also the upper rings 20 of the manipulators. In this case, under the action of the springs 10, the brackets 3 are lowered and pressed by the rollers of the part 5 of the stitched Blanks to the fixed lid of the lower manipulator rings acting as the needle plate. Since the rollers k are located at an angle to the direction of the main feed (FIG. 2), they shift the part 5 along the needle to the stops 6 and 7, thus providing the required amount of mutual overlap of the parts. The invention The device for automatic rotation of parts relative to the needle of the author. St. No. 751858, of a sewing machine in accordance with the fact that, in order to increase its productivity, it has two guide rollers for contacting each one of the parts to be ground, mounted on the sewing machine foot by means of spring-loaded brackets, and two stops for parts one of which is mounted on one of the drive rings, and the other on the axis of one of the guide rollers.
