Automatic vulcanization shoe foxing strip attaching method

Abstract

The invention provides an automatic vulcanization shoe foxing strip attaching method. The method comprises the steps of pre-preparation, image acquisition, image processing, shrinkage compensation andthe like. An industrial camera of a scanning device completes one revolution around a vulcanization shoe semi-finished product along a specific path in the image acquisition step, and shrinkage quantity of inward shrinkage of a scanning track at positions corresponding to a toe cap and a heel relative to an actual attachment track is reduced as much as possible; meanwhile, in the shrinkage compensation step, a specific attachment device is adopted and a compression spring of the attachment device compensates the shrinkage quantity of the scanning track, thus the change of extrusion force received by a foxing strip when the foxing strip is attached is relatively small, the foxing strip does not deform easily, the attachment error is small, the production efficiency is relatively high, andthe attachment quality is relatively good.

Description

technical field [0001] The invention relates to a method for attaching a skirt, in particular to a method for automatically attaching a vulcanized shoe skirt. Background technique [0002] In the production of vulcanized shoes, it is necessary to attach a strip at the junction between the upper and the sole to strengthen the strength of the shoe and make the appearance more beautiful. [0003] At present, the attachment of vulcanized shoe skirts is mainly done by manual paste, the production efficiency is relatively low, and the attachment quality depends entirely on manual work, resulting in unstable product quality. There are also some enterprises that use equipment such as manipulators to realize the automatic attachment of the fences. Although the production efficiency can be improved, the quality of the attachment is relatively low. Attachment track, the attachment track is also the shape of the enclosure attached to the vulcanized shoe, the shape is as figure 1 As sh...

Problems solved by technology

[0003] At present, the attachment of vulcanized shoe skirts is mainly done manually, the production efficiency is relatively low, and the attachment quality depends entirely on manual labor, and the product quality is unstable.

There are also some enterprises that use manipulators and other equipment to realize the automatic attachment of the fence. Although the production efficiency can be improved, the quality of the attachment is relatively low. Attachment track, the attachment track is also the shape of the enclosure attached to the vulcanized shoe, the shape is as figure 1 As shown, it is a closed-loop and irregular shape formed by the connection of multiple curves. The radius of curvature at the position corresponding to the toe and the heel is relatively small, while the radius of the crank at the position corresponding to the waist is relatively large. Therefore, if Directly use the scanning device to rotate around the vulcanized shoe and obtain the attachment track for the junction position between the upper and the sole, the attachment track will be due to the distance between two adjacent phase acquisition points of the industrial camera of the scanning device There is a difference between the actual attachment trajectory and the actual attachment trajectory. Specifically, the attachment trajectory acquired by the scanning device will shrink inwards relative to the actual attachment trajectory at the position corresponding to the toe and heel. In addition, the scanning device will In the process of forming the attachment trajectory through fitting processing, in order to ensure smooth trajectory, it is inevitable to perform interpolation filtering, and the above-mentioned shrinkage phenomenon may also occur. The existence of the shrinkage phenomenon makes the manipulator stick with the attachment trajectory obtained by the scanning device. During the process of attaching the surrounding strip, the extrusion force on the surrounding strip changes relatively greatly, which makes the surrounding strip deformed, and the error of attaching the surrounding strip is large, which affects the attachment quality
