Description

Automatic label feeding device

Technical Field

The utility model relates to a label production check out test set, concretely relates to label automatic feeding device.

Background

The labels in the prior art are divided into a number of forms, one of which is a sheet-like sticker, such as a product label that is affixed to the outside of a shoe box. The label is relatively large in area, made of paper, flexible and light in weight. Before the production of the label is finished, quality detection is needed, the purpose of detection is mainly to determine whether the product is flat and complete in shape, and if printed contents exist, whether the printed contents are correct and clear needs to be detected. Therefore, the detection process requires the camera to completely shoot the whole label. In addition, due to the independence and light weight of the labels, the conveying device cannot use a conveying belt structure, and the reasonable mode is that the single label is grabbed and conveyed reasonably by using a sucker structure.

There is a material loading detection mechanism among the current technical scheme, as shown in fig. 1, mainly include that platform base A1 snatchs module A2 with the label, horizontal drive module A3 and material loading module A4, the label snatchs module A2 and drives it at straight line translation motion through horizontal drive module c3, the label snatchs module A2 and snatchs the label that piles up in material loading module A4 automatically, the translation is through the image detection module A5 of shooting from bottom to top that material loading module A4 one side set up, thereby complete discernment is to whole label, and then carry out quality testing to the label. It has solved the problem that the label snatchs module and image detection module mutual interference through the mode of shooting from bottom to top, nevertheless has following defect:

in order to guarantee the accuracy of detection, image detection module A5 shoots the in-process, it keeps quiescent condition to need the label, thereby lead to drive module A3 with the label conveying to next station in-process need pause when passing through image detection module A5, and because horizontal drive module A3 generally uses the motor as power, start-stop every time all can influence certain output efficiency, consequently once snatch under the condition of a slice label using single sucking disc mechanism, overall efficiency is lower, can't satisfy the requirement of getting fast to the label is automatic in current actual production process label material loading detection mechanism.
