Outline measuring device and control method thereof

Abstract

The invention provides an outline measuring device and a control method thereof. The outline measuring device is used for measuring an outline of a shoe upper, and the device comprises a mechanical arm, a feedback sensor, an outline path adjusting module. A measuring unit of the mechanical arm abuts against the shoe upper along an original outline path to shift, so that the shoe upper correspondingly generates displacement. The feedback sensor is connected with the measuring unit, and senses and records the displacement. The outline path adjusting module is connected with the mechanical arm and the feedback sensor, and the outline path adjusting module calculates and corrects the original outline path and generates a preset outline path according to the displacement, so that the measuring unit shifts along the preset outline path. Firstly the displacement of the shoe upper is read through the mechanical arm by combining with the feedback sensor, then the operation is conducted by using the displacement, the preset outline path is obtained, the different material is judged, and then the accuracy and efficiency of roughing are improved.

Description

technical field [0001] The present invention relates to a contour measurement device and its control method, in particular to a contour measurement device and its control method which utilizes the displacement of the vamp to determine the contour and judge the material. Background technique [0002] The upper path plays a very important role in the entire shoe manufacturing process, and it is used in all roughing, gluing, or sewing processes. Therefore, in the fully automated shoe-making process, the precise upper path is an important basis for the successful realization of automatic shoe manufacturing. [0003] At present, there is a known technology, which is a three-dimensional measurement system and a three-dimensional measurement method for bonding marking lines between soles and uppers. It mainly uses a three-dimensional scanner to automatically measure the three-dimensional structure of the inner surface of the sole to form a three-dimensional surface for the shoe upp...

Problems solved by technology

However, this technology still cannot know the material and hardness of the upper in real time, so it is prone to excessive or insufficient roughening

[0005] As far as general shoe upper materials are concerned, most of them are soft materials. During the roughing process, the roughing equipment may cause the soft material to collapse when it touches the upper. How deep should the device be set before it can start running along the periphery of the upper?

Therefore, it is easy to cause excessive or insufficient roughening

If the thickness is too thick, although the viscosity is excellent, it is easy to cause glue overflow after subsequent application; on the contrary, if the thickness is too shallow, although the glue will not overflow, the viscosity is not enough to make the sole and the upper completely. bond

The difference in the height of the fabric on the shoe surface cannot be known through the general roughening device, so the roughening effect is not ideal, and often needs to be roughened several times to overcome it.

[0006] It can be seen that there is currently a lack of a contour measurement device and its control method that can quickly determine an accurate and ideal roughing path and instantly determine the material in the market, so relevant companies are all looking for a solution
