Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a quilting machine capable of sewing gears.

B. Conventional technology A quilting machine is a machine that continuously sews long or short fabrics using multiple needles.

In recent years, many special sewing machines have been designed to use rollers, or in the case of short fabrics, belt feeding and feeding rollers, to form stitches at predetermined intervals on long or short fabrics using multiple needles. In order to meet this demand, there are increasing demands for quilting machines that can perform gear stitching, but no machine that satisfactorily meets these demands has been provided.

C.9 Problems to be Solved by the Invention These gear stitch quilting machines have a complicated structure and are not satisfactory in terms of improvement in N manufacturing efficiency, etc. In view of the above-mentioned circumstances, in the present invention, a quilting machine having a simple configuration,
The purpose is to achieve efficient gear sewing.

20 Means and Function for Solving the Problems In the present invention, in a machine that quilts upper and lower fabrics using multiple needles, which are fed out by upper and lower feed rollers, the swinging motion of a crank connected to a drive shaft is used. Through a link mechanism, the gears are converted into a rotational motion of the shaft that operates the device that forms gears on the upper fabric, and the gear feeding means of the gear forming device is slid back and forth on the sliding plate, thereby forming gears on the upper fabric. Provides a configuration to form. The feed plate, which is the gear feed means, slides back and forth on the sliding plate together with the feed spring in accordance with the rotation of the shaft, forming gears on the upper fabric, and by the cooperation of the needle and presser foot [1], gears are formed on the upper fabric together with the lower fabric. It is also possible to perform sewing quilting.

E, Example An embodiment of the present invention will be described below with reference to the accompanying drawings.

A drive wheel 6 and a crank 8 are attached to the upper shaft 4 which is rotatably supported on the side plate 2 of the quilting machine main body, and the cam ball lO of the crank 8 is rotatably pivoted on the protruding arm 14 of the support plate 12. A long groove 20 bored in the supported first operating arm 18
to fit. The end of the first actuating arm 1B is pivoted 24 to another second actuating arm 22 into which a rotation shaft 28, which will be described later, is inserted and fixed.
be done. A rotating wheel 28 is rotatably supported on a pair of side plates 26 attached to the support plate 12 . [Plate 26,
A plurality of feed arms 30 are fitted and fixed at predetermined intervals on the rotating shaft 28 between the feed arms 2B, and the sliding plate 32 is connected to the feed arms 3.
0 so as to form a predetermined inclination toward the front (toward FIG. 1), and is supported by a support plate 35 provided on the side plate 26. A feed plate 3B having a feed spring plate 34 fixed to the opposite end thereof is pivotally attached 38 to one end of the feed arm 30. Reference numeral 40 designates a spring member having one end wrapped around the rotary wheel 28 and the other end pressing against the feed spring plate 34. A pair of support plates 42 are attached to the outside of the side plates 26, and a fabric support rod 44 is installed across the side plates 28,28.

In addition, a cloth presser 48 and needles 50 attached to a plurality of needle bars are provided in the vicinity of the sliding plate 32. Code 52.54
are feed rollers that pull and feed the upper and lower fabrics in the direction of the arrow.

The upper fabric is indicated by Wl, and the lower fabric is indicated by W2. Further, reference numeral 56 is a machine frame, and 58 is a thread guide.

Next, the operation of this embodiment will be explained. -h fabric W1
The material passes through between the dough support rods 44 installed on the support plate 42, is fed in the direction of the arrow as shown in FIG. It passes through and is located below the feed spring 34. On the other hand, drive wheel 6
As the drive shaft 4 rotates and the crank 8 is oscillated by the operation of Part 1
B as a fulcrum, the second actuating arm 22 pivotally attached to the end of the first actuating arm 18 swings Ngh in the direction of the arrow along with the rotation axis 28. As the rotation shaft 28 and feed@30 also move in the same direction, the feed plate 36, which is pivotally attached to the end of the feed arm 30, slides back and forth on the sliding plate 32 together with the feed spring 34, and the feed @30 moves in the same direction. The upper end of spring 34! Form gears on W1. At this time, the spring member 40 presses the feed spring 34 and serves to facilitate the formation of gears. Pass under and above.

It is held between lower feed rollers 52 and 54 and sent out in the forward arrow direction. Meanwhile, upper and lower fabrics Wl and W2 have multiple stitches of 50
Of course, it is sewn with.

The depth of the gears formed on the upper material W+, the number of gears formed in a certain period of time, etc. are determined by the rotation angle of the drive shaft 4, L, the lower material, and tI! ! It can be freely set by adjusting the feed speed of W' and W2.

1. Effects of the Invention The present invention has an extremely simple configuration and has the advantage of being able to carry out gather stitching using a quilting machine.
