A fully automatic shoe sole gluing and marking machine

Abstract

A fully automatic shoe sole gluing and marking machine, including a controller, a workbench, a marking device and a sole rotating device; the marking device includes a first rotating motor, a first rotating shaft, a first base, a translation mechanism, a telescopic pen and a stroke The sensor and the sole rotating device include a second rotating motor, a second rotating shaft, a second base and a sole fixing device. When the stroke sensor detects that the telescopic pen extends forward to the maximum distance, the sole does not move, the telescopic pen moves forward, and draws a marking line with a small arc on the side of the sole through the rotation of the telescopic pen. When the first shaft rotates past the preset Angle, the telescopic pen moves backwards, the telescopic pen does not move, and draws a large arc marking line on the toe or heel through the rotation of the sole. In this way, through the cycle switching of two different marking methods, the arcs are respectively completed. The marking of the side of the sole, the toe or the heel with large differences can avoid jamming, the operation is quite simple, the production efficiency can be greatly improved, the error can be reduced, and the marking accuracy can be improved.

Description

technical field [0001] The invention relates to a shoe sole processing equipment, in particular to an automatic shoe sole gluing and marking machine. Background technique [0002] In the shoe manufacturing industry, the sole and the upper are generally produced separately, and then the sole and the upper are attached to each other, usually by glue. Therefore, it is necessary to pre-coat an adhesive layer on the side of the sole. The adhesive layer A certain height requirement needs to be met and the sides of the sole cannot be completely painted. Therefore, before applying glue on the side of the sole, it is often necessary to draw a circular marking line on the side of the sole according to the predetermined gluing requirements, and then apply glue on the side of the sole below the marking line, so as to ensure that the glue applied Layers meet predetermined requirements. However, due to the unevenness of the side of the sole, it is difficult for the marking line on the s...

However, due to the unevenness on the side of the sole, it is difficult to automatically mark the marking line on the side of the sole

In the past, we had the idea that the scribing pen is fixed and the automatic scribing is achieved by the rotation of the sole, but this idea does not work at all, because the scribing pen and the toe, heel, and sole of the sole The distance between the sides is too large. During the rotation of the sole, the line between the scribing pen and the sole must be stuck due to the sudden change in the distance. This problem has not been solved. Therefore, at present, in the shoemaking industry, it can only be done by hand. Scribing, manual scribing requires workers to hold the sole in one hand and a pen in the other hand for circular scribing. It is necessary to constantly change the angle of the sole and adjust the angle of the pen tip, which is quite troublesome and the production efficiency is low. Error prone, not very precise
