Abstract
Description
Technical Field
[0001] The invention relates to a tooling fixture for automatic single-needle sewing equipment for hats. Background Art
[0002] Sewing a hat requires 26 processes and several parts. The crown part is made of 6 pieces of fabric, which are sewn one by one according to the process flow to form a hemispherical crown. Each piece of fabric needs to be sewn with a single needle once, and then sewn with a double needle once and double needle cloth is added. Now many hat sewing processes are mostly completely manual. It is necessary to develop an automated hat production line. In the automated production line, single needle sewing is one of the important steps. The process is to align the two pieces of fabric and sew one of the edges with a single needle flat sewing machine. This process was previously performed manually. There are the following problems with manual operation: one is poor repeatability and the size of the sewing is not standardized; the second is that the quality of the sewing is not controlled and it is easy to make mistakes; the third is that the manufacturing industry needs to be transformed and upgraded, and personalized customization and other demands have become the development trend of the clothing industry. Intelligent and automated transformation must be carried out to meet the needs of development.
[0003] The purpose of the invention is to provide a tooling fixture for single-needle hat sewing automation equipment, which solves the problems of poor repeatability during manual operation in the prior art, unstandardized sewn size, uncontrolled sewing quality, and easy mistakes.
[0004] The technical solution of the present invention is:
[0005] The invention discloses a tooling fixture for a single-needle hat sewing automation device, which comprises a set of a template pressing plate and a mounting seat, wherein the template pressing plate comprises a guide pressing plate and a floating pressing plate, wherein the rear portion of the guide pressing plate is mounted on the mounting seat via a vertical rotating support shaft, and the floating pressing plate is mounted below the front end of the guide pressing plate via an adjustable flexible positioning connection structure, and the guide pressing plate and the floating pressing plate can passively rotate along the rotating support shaft at the same time under the guidance of a sewing machine guide wheel;
[0006] The front ends of the guide pressing plate and the floating pressing plate have the same outer contour curves, which are set to be the same as the edge shape of the material to be sewn, and the single-needle sewing process is completed during the rotation process;
[0007] A mounting plate is fixed at the rear of the mounting seat, and the tooling fixture can be mounted on the multi-axis motion servo mechanism through the mounting plate and driven by the multi-axis motion servo mechanism.
[0008] Furthermore, the adjustable flexible positioning connection structure of the floating pressure plate and the guide pressure plate described in the present invention is: a row of positioning holes are correspondingly arranged on the floating pressure plate and the guide pressure plate, an optical axis guide rod is arranged in each pair of corresponding upper and lower positioning holes, and the upper and lower ends of the optical axis guide rod are respectively provided with a mounting cap, the two mounting caps are respectively fixed on the guide pressure plate and the floating pressure plate, the optical axis guide rod can make a limited displacement in the mounting cap in the upper and lower directions, and a spring is sleeved on the optical axis guide rod between the floating pressure plate and the guide pressure plate.
[0009] When the device of the present invention is working: the multi-axis motion servo mechanism presses the two aligned pieces of cloth on the work surface by moving up and down; the multi-axis mechanism interpolates in linkage, so that the cloth pieces move between the work surface and the sewing machine according to the specified contour curve. The shape of the guide pressing plate is the specified contour curve, and the multi-axis motion servo mechanism drives the fixture to ensure that the floating pressing plate is in close contact with the sewing machine to form a mold processing, and the fixture presses the cloth pieces to move according to the specified contour curve. The single-needle sewing process is completed during the movement.
[0010] The beneficial effects of the present invention are as follows: At present, most of the general hat sewing enterprises use manual sewing equipment to complete the entire hat production process. No matter how strictly the workers operate according to the specifications and how good the workers' skills are, it is difficult to avoid the following problems: first, the repeatability is poor, the size of the sewing is not standardized; second, the quality of the sewing is not controlled, and it is easy to make mistakes. And to establish a set of automated production lines, one of the important links is that the crown processing part needs to sew 6 pieces of cloth one by one according to the process flow, and finally form a hemispherical crown. Single-needle sewing is required between each piece of cloth. At this time, an accurate automated clamping tool is required to cooperate with the automatic sewing machine to complete this action, and the holding tool is very important. The use of the tool of the present invention in conjunction with the automatic control sewing machine can well realize the automatic single-needle automatic sewing of the cloth piece, which has high work efficiency, good repeatability, low error rate, can be customized, and is suitable for cloth pieces of different sizes. Moreover, the tool structure design of the present invention is simple and reasonable, easy to control, good accuracy in completing the action, and low cost. It is a very excellent tooling fixture for automated hat single-needle sewing equipment. BRIEF DESCRIPTION OF THE DRAWINGS
