Mouth expanding and bag opening device for woven bags

Abstract

The invention relates to the technical field of automatic filling equipment for bulk materials, and specifically relates to a mouth expanding and bag opening device for woven bags. The mouth expandingand bag opening device comprises a bag opening mechanism, a mouth expanding device and a cleaning device for the woven bags, wherein the mouth expanding device is used for sucking-expanding the mouths of the woven bags; the bag opening mechanism is used for opening the sucked-expanded woven bags and loading the woven bags; and the cleaning device for the woven bags eliminates the woven bags whichare not successfully subjected to bag opening to avoid influence on the subsequent procedures. The mouth expanding and bag opening device is capable of realizing automatic mouth expanding for the woven bags, and carrying out bag opening for the woven bags on the woven bags with different specifications, capable of accurately identifying the action of grabbing failure of a manipulator, reasonablein design, reliable in working, high in practicability, and capable of timely removing and cleaning the woven bags with failed bag hanging, so that the mouth expanding and bag loading efficiency for the woven bags is increased.

Description

technical field [0001] The invention relates to the technical field of automatic filling equipment for bulk materials, in particular to a woven bag opening and bag supporting device. Background technique [0002] In the bulk material filling industry, especially in the grain, oil, food, feed, cement, chemical and other bulk material filling industries, due to factors such as production costs, manufacturers often use low-cost woven bags to fill materials. Woven bags are divided into two types: film-coated and non-film-coated. At present, in terms of automatic filling and packaging, there are already good methods for automatic hanging of woven bags with film, but for woven bags without film , due to the high air permeability of the non-coated woven bag, and when the woven bag is made and cut, the eager method is often used, causing the woven bag to stick.

AI Technical Summary

Problems solved by technology

Woven bags are divided into two types: film-coated and non-film-coated. At present, in terms of automatic filling and packaging, there are already good methods for automatic hanging of woven bags with film, but for woven bags without film , due to the high air permeability of the non-coated woven bag, and when the woven bag is made and cut, the eager way is often used, causing the woven bag to stick

At present, the vacuum system of the vacuum generator is mostly used in the industry, and the negative pressure adsorption makes the woven bag open automatically, or the woven bag is opened with a sharp needle-like object, or the woven bag is bonded with adhesive tape. , but the above method often cannot make the woven bag open smoothly when carrying out the action of opening the bag to hang the bag.

At present, most of these devices use the bag-hanging manipulator to realize the automatic bag-hanging action, but because different manufacturers may have various specifications of bulk packaging bags, such as 50KG and 70KG packaging bags, this requires that the bag-hanging manipulator must be able to handle different The standard packaging bags are hung, and most of the existing automatic bag hanging equipment cannot meet this requirement

In addition, during the bag hanging work of the woven bag, the hanging bag may fail, and the manipulator fails to grab the woven bag. If the woven bag that failed to hang the bag is not removed in time, it will affect the subsequent bag hanging work of the manipulator and require manual labor. Timely stop and clear, reduce the efficiency of bag support and filling efficiency

As a result, the working efficiency of the automatic filling equipment is low and the production efficiency is affected.
