Technical Field

The invention relates to the field of quilting machines, in particular to a computer quilting machine needle and rotating shuttle gap compensation control method.

Background

At present, most of general computer single-needle quilting machines on the market have principle defects. During the quilting of the machine, the machine needle is in the running stage under the cloth (the time is about 30 percent of one needle period), because the quilted material is continuously moved, the machine needle can be pulled and deformed, if the needle pulling direction is to increase the gap between the machine needle and the rotating shuttle point, the problem of sewing thread jumping is often generated; in the opposite direction, the shuttle point needle punching phenomenon is generated, and the machine needle is broken to cause a fault when the machine needle is serious; meanwhile, the service life of the rotating shuttle is shortened. The root of these phenomena is that the quilting machine is heavy and large in moving part, and the high-speed operation vibration is serious, so that it can not do gap movement like that of embroidery machine, i.e. the sewing material is still when the machine needle is under the cloth, and the same is true of ordinary flat sewing machine.

The traditional technology has the following technical problems:

the earliest machine type in the world to solve the problem is a Japanese prince brand quilting machine, and the machine head rotating mode is adopted, namely the machine head always rotates along the change of a flower-shaped track, so that the gap between a machine needle and a rotating shuttle is not changed by pulling the needle. But the rotary mode of the machine head also has the disadvantages that firstly, when the instantaneous rotating angle is larger, the operation efficiency is reduced due to inertia factors, and secondly, the structure is complex and the cost is high. In addition, the left and right movement of the machine head is driven by an upper synchronous belt and a lower synchronous belt at present, so that continuity errors can occur in the movement process of the machine head and the machine base, the machine head and the machine base are deviated left and right, a machine needle cannot be always kept at the central line position of the machine base, and unstable line hooking can be caused in the high-speed sewing process, so that line breakage is caused. Some special models adopt the scheme.

Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

The time part of the machine needle under the cloth is determined, the offset of the pull needle is related to the needle pitch, the movement direction, the needle thickness and the density of a quilted object, the former two are fixed values, the offset of the needle can be obtained through calculation, the contribution of the latter to the pull needle can obtain an empirical value through experiments, the final value is connected with a control system, a double-layer mechanism is used for driving a machine base, the movement of the machine base in the X direction and the Y direction is quickly driven by software and an execution mechanism to the machine base or a machine head, the real-time compensation in the quilting process is completed, the sewing quality, the working reliability and the rotating shuttle abrasion of the machine can be greatly improved, particularly for the objects needing to be sewn by using thin needles (10-11), the scheme is a novel competitive method, the investment of a user in the equipment can be reduced by half, and the novel method has high economic value.

The electrical appliance control idea is as follows:

1. a driving motor (servo motor) is used for driving a fine adjustment mechanism, so that a rotating shuttle seat or a needle is driven, a system sends out pulses to control the motor so as to achieve a compensation function, and the effect of dynamically adjusting two distance values of L1 or L2 is realized; wherein the value of L1 refers to the distance of the rotating shuttle seat from the X direction of the needle, wherein the value of L2 refers to the distance of the rotating shuttle seat from the Y direction of the needle;

2. calculating a specific numerical value to be compensated according to real-time judgment of the running track during working, and giving a quantitative pulse by the system to timely give compensation (controlling the value of L1 or L2) by matching with the running period of XYZ three axes;

3. the type of the fabric of the currently produced product can be input into the system, and then the system can automatically judge the value needing compensation according to the input type of the fabric (the value of the control L1 or the value of the control L2).
