AI Technical Summary

Technical Problem

When conveying Tetra Pak boxes on the conveyor belt, some Tetra Pak boxes will be inverted, resulting in the failure of laser inkjet operation. Especially when the conveyor belt is long, the inverted bag is more common.

Method used

A Tetra Pak box inverted bag removal device is designed, including a front upper barrier rod, a front lower barrier rod and a rear barrier rod on the conveyor belt. The notch section and the inverted bag collection container (can be a net bag) are used to combine the bag push mechanism to automatically identify and remove the inverted bag Tetra Pak box.

Benefits of technology

It effectively avoids the inverted Tetra Pak box entering the subsequent station, resulting in the failure of laser injection and coding operations, and improves the stability and efficiency of the production process.

Abstract

The utility model discloses an inverted tetra pak bag removing device. The device comprises a conveying belt, the front side of the conveying belt is provided with a front side upper blocking rod and a front side lower blocking rod which extend in the conveying direction, and the rear side of the conveying belt is provided with at least one rear side blocking rod; the lower edge of the front side upper blocking rod is higher than the inverted tetra pak box, and the lower edge of the rear side blocking rod is lower than the inverted tetra pak box; a notch section is arranged between the front side lower blocking rods, and a bag-to-bag collecting container is arranged at the position of the notch section and located below the conveying belt. The device can automatically reject ladle-to-ladle products on the conveying belt, and avoids the situation of failure of laser code spraying operation caused by ladle-to-ladle.
