Sewing box replacing device, driving method thereof and sewing machine

Abstract

The present invention relates to a sewing box replacing device, a driving method thereof and a sewing machine comprising the sewing box replacing device. The sewing box replacing device of the invention comprises sewing boxes used for fixing the above sewed objects and arranged in a Y-shaft direction on the upper surface of a workbench; a Y-shaft conveying unit conveying the sewing boxes to the Y-shaft to execute the sewing performance, conveying the finished sewing boxes backwards at the same time, and conveying the to-be-sewed sewing boxes to a head side to execute the sewing performance to thereby realize the replacement of the sewing boxes. By replacing the sewing boxes automatically, even though a lot of sewing performance is executed, the sewing box replacement time can be shortened substantially, and the work efficiency is improved substantially; by spacing a Y-shaft driving part of the sewing machine apart from a bottom frame, the work region towards Y-shaft direction ( the front and back length directions) can be expanded without limited by the size of the sewing machine, so that the sewing box replacing device, the driving method thereof and the sewing machine have the effects of sewing large-scale sewed objects.

Description

technical field [0001] The present invention relates to a sewing frame replacement device, a driving method thereof, and a sewing machine including the sewing frame replacement device. More specifically, the sewing frame for fixing a sewing object is automatically replaced to continuously perform sewing operations of a plurality of sewing objects A sewing frame replacement device, a driving method thereof, and a sewing machine including the sewing frame replacement device. Background technique [0002] figure 1 Showing an example of a conventional sewing machine, the arm portion 40 including the head is located on the upper side of the table 10, the bottom plate portion (not shown) including the hook (Hook) is located on the lower side of the above-mentioned table 10, and the above-mentioned arm is connected by The joint part 60 of the part 40 and the bottom plate part is comprised, and the sewing object fixed to the sewing object fixing part 50 is sewn by the cooperation o...

Problems solved by technology

[0006] However, in conventional sewing machines, when a new operation is performed after sewing one operation object, the operator needs to directly replace the sewing frame, which consumes a lot of time for replacement, and the larger the sewing object, the longer the sewing required. The larger the frame, the heavier the burden on the operator and poor workability

[0007] In addition, the conventional sewing machine sews while transferring the sewing object by X-Y driving in the table of the sewing machine, so the size of the sewing object is inevitably limited by the size of the table, which makes it impossible to perform sewing on a large-area sewing object. sewing defect
