Bottom surface labeling machine

Abstract

The invention discloses a bottom surface labeling machine which comprises a controller, a first conveying mechanism used for inputting a to-be-labeled product and a positioning and clamping device, wherein the first conveying mechanism is electrically connected with the controller; the positioning and clamping device comprises a material clamping mechanism arranged above the first conveying mechanism and is electrically connected with the controller, the material clamping mechanism comprises a drive part, a fixed seat in drive connection with the drive part and at least three material clamping and correcting fingers arranged on the fixed seat; the at least three material clamping and correcting fingers can rotate relative to the fixed seat, are arranged in a surrounding manner to form a material clamping chamber and can be relatively-close to or far away from one another. Thus, through the characteristic that the material clamping and correcting fingers can rotate relative to the fixed seat, the bottom surface labeling machine can better adapt to clamping, positioning and pose correction of irregularly-shaped products, so that the poses of the irregularly-shaped products are adjusted to be aligned with the height of a labeling station, the product labeling precision is greatly improved, and the higher product production quality is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic labeling, in particular to a bottom labeling machine. Background technique [0002] In order to indicate the composition formula of the product, production-related information, etc., most commodities currently need to paste labels or trademarks on the surface of the product or the surface of the outer packaging bag of the product. In order to improve work efficiency, most manufacturers use automatic labeling equipment for labeling processing. The working process is roughly that the jaws of the labeling equipment grab the product to be labeled for positioning and calibration of the labeling position, and then the jaws grab the product to be labeled. The labeled products move together to the labeling station to complete the labeling, and finally the grippers transport the labeled products and place them on the conveyor belt to enter the next process. However, the grippers of the above-mentioned t...

Problems solved by technology

However, the grippers of the above-mentioned traditional labeling equipment can only achieve high-precision clamping and positioning for products with regular shapes, and when the shape of the product is irregular, the grippers often cannot effectively and accurately position the product. Clamping and positioning will cause the labeling position of the product to be inaccurate and high-precision alignment with the labeling equipment, which will affect the labeling accuracy of the label or trademark, resulting in product quality that does not meet the requirements, resulting in rework or scrapping, and increasing the production of the enterprise cost
