Electronic cam take-up device used for computer embroidering machine, and take-up method thereof

Abstract

The invention discloses an electronic cam take-up device used for a computer embroidering machine, and a take-up method thereof. The device comprises a computer embroidering machine control system, an electronic cam take-up driving plate, a take-up motor assembly, a take-up mechanism component and a position sensor, and the computer embroidering machine control system is connected with a main shaft photoelectric encoder; the position sensor is used to detect the initial position of the electronic cam take-up driving plate; the electronic cam take-up driving plate is connected with the main shaft photoelectric encoder; the electronic cam take-up driving plate is connected with the take-up motor assembly; and the take-up motor assembly is connected with the take-up mechanism assembly. The device continuously controls the position of a take-up motor through monitoring the angle and position information and the rotating direction information of a main shaft according to parameters preset by the computer embroidering machine control system and a built-in electronic cam curve in order to adjust the take-up position in real time, realizes the setting of the take-up curve and the take-up angle of a computer embroidering machine, and improves the take-up accuracy and consistence of the machine.

Description

technical field [0001] The invention relates to the field of computer embroidery machines, in particular to an electronic cam thread take-up device and a thread take-up method for computer embroidery machines. Background technique [0002] The embroidery principle of the computerized embroidery machine is similar to that of a sewing machine. The upper thread penetrates the fabric through the needle, and the upper thread is hooked by the lower hook, and the bottom thread in the hook is circled to form a thread knot. When the hook hooks the upper thread and rotates for one circle, the thread take-up lever needs to be fed by the hook in the previous stage to pull the thread, and the thread take-up lever needs to be taken up by the thread take-up lever in the latter stage when the hook is off the thread. The cooperation of thread take-up and hook plays an extremely important role in the embroidery process, which directly affects the embroidery and thread breakage rate of the mac...

AI Technical Summary

Problems solved by technology

However, the existing thread take-up cams are installed inside each machine head and set on the main shaft, so it is extremely difficult to change and adjust the types and angles of the cams, which cannot meet the ever-changing needs of users.

[0005] Secondly, because the thread take-up mechanism on each machine head is relatively independently installed and positioned, it is inevitable that there will be mutual differences, so the embroidery effect produced by each machine head will not be uniform and the quality will vary greatly.

[0006] Furthermore, the thread take-up work is completed by the rotation of the nylon cam to drive the bearing movement. The accumulated wear and tear makes the thread take-up accuracy worse and worse until it needs to be replaced.
