Description

Shoemaking assembly line

Technical Field

The invention relates to a shoemaking assembly line.

Background

In the field of shoe making, there are many processes, each process consists of dozens to hundreds of processes, in most processes, the whole shoe making process is carried out by combining two processes of making uppers and soles, taking the most common shoe gluing process as an example, an upper making workshop needs to cut raw and auxiliary materials such as a whole piece of leather into each part of a vamp, and the whole vamp is made by processes of splitting, bonding, sewing, shaping and the like, a forming workshop needs to bond the vamp and a sole, namely the sole combining process, so as to make a pair of complete shoes, wherein the processes comprise a series of processes of vamp shaping, cleaning, light spraying, glue brushing, cold and hot shaping and the like.

The assembly line is also called assembly line, in industrial production, it can greatly reduce operation time and raise efficiency, and in the present, shoe-making forming workshop basically adopts assembly line operation, and shoe-making upper workshop, such as needle-sewing line, also can partially adopt assembly line operation. The method is characterized in that a pre-process of an upper making process is required to cut raw and auxiliary materials such as leather surface, lining, hot melt adhesive, foaming material and the like into parts with specified specifications in a shoe making process diagram through cutting, the parts are combined with each other to form a complete upper, namely the upper making process needs to take all parts forming the upper in the last cutting process to completely process one upper, taking natural leather as an example, the animal size of the natural leather cannot be completely consistent, in order to fully utilize the leather, the existing leather basically has no natural leather with completely consistent leather surface size, and the flaws of the leather surface caused by the wound or sore of the animal leather surface cannot be used for processing the upper parts, so that the number of the parts which can be processed by one leather is inconsistent, the left foot and the right foot of a common shoe are equally divided, therefore, the processed parts also need to be doubled, and the actual processing method is that one cutting station cuts one piece of natural leather into different parts of the same style of shoe The actual processing time needs more than half an hour, which is one of the reasons that the assembly line is difficult to be practically applied in the cutting process, the reason is that a single part is downwards distributed in the assembly line mode, the next process cannot be processed but is disordered, the current order mode is forward converted to a small batch of orders with multiple styles, the assembly line is often required to be doped with multiple shoes, the parts of the multiple shoes are distributed in the next process in the cutting process, errors are easy to cause, in the actual production process, after the parts of all materials are cut, the parts are conveyed by a specially-assigned person in the same centralized mode, corresponding materials such as art books and the like are put into the field, the manufacturing of different shoe types is completed by different stations, and the cutting process to the upper making process needs more than 30 hours.

Disclosure of Invention

The invention aims to provide a shoe making production line, in particular to a production line suitable for a cutting process, and solves the technical problems that the cutting process has more parts and is complex and has the characteristic of complete combination, a single part cannot flow to the next process to process and needs to wait for other parts, a plurality of shoes cannot accurately acquire process drawings, exploded views and sample drawings of corresponding shoe styles in the simultaneous production, the production line processing of the cutting process is realized by arranging a conveying belt which can uniformly convey different parts of a plurality of stations to the next process after gathering, and bar code stickers with the contents of the process drawings, the exploded views and the sample drawings are arranged on the parts to accurately acquire technical files required by processing, so that the efficiency is improved, and the waiting time is saved.
