Template changing device for pattern sewing machine and pattern sewing machine

Abstract

The invention relates to a template changing device for a pattern sewing machine and the pattern sewing machine. According to the template changing device for the pattern sewing machine, a workbench is provided with a template changing station, the template changing station is provided with a transfer station and at least one machining station in the circumferential direction, and each machining station is correspondingly provided with a sewing device. The grabbing action of machined sewing templates from the machining stations to the template changing station is achieved through a taking mechanism of the template changing device, and the feeding action of transferring new sewing templates on the template changing station from the template changing station to the machining stations again is achieved through a feeding mechanism. A transfer mechanism is used for replacing a sewing template at the template changing station, manual whole-process participation is not needed in the whole template changing process, the taking and feeding actions are coherent and rapid, and the device is very suitable for fast-paced assembly line machining.

Description

technical field [0001] The invention relates to the field of sewing devices, in particular to a mold changing device for a pattern machine and a pattern machine. Background technique [0002] In order to meet the increasingly diverse sewing needs, the pattern machine usually adopts the method of changing molds to match different sizes and styles of molds, so that when the production target changes, the pattern machine can be used in the existing structure without major changes. Basically, only a small amount of disassembly and replacement is required to quickly put it into use. Such a change can greatly reduce the investment of enterprises in equipment, which is very practical. [0003] However, in some special scenarios, some raw materials require complex production processes. In the process of completing a sewing process, different molds need to be used. This requires the pattern machine to have the ability to change molds in real time to ensure that the entire The sewing...

Problems solved by technology

[0004] Although the above-mentioned pattern machine meets the needs of mold change to a certain extent, on the one hand, the mold change in the form of flipping is slow, and there are high requirements for the fixing and locking of the mold, which cannot meet the fast-paced production needs. On the other hand, the two mold changing devices are only used side by side, and there is no connection in the process and process. The actual mold changing still requires manual real-time participation in the operation, which cannot be fully automated, and is still very inconvenient.
