Abstract
In an effort to increase efficiency of the process of handling of an air-penetrating flexible container during its’ filling with free-flowing materials a devise has been designed for automatic gripping, opening, holding and sealing of flexible container, containing vacuum gripping devise, pneumatic drive for its’ transfer and a control system based on programmable logical controller. Vacuum gripping device can be produced using the method of additive technologies. It has a modular structure, while each module contains random or structured vacuum chambers located on work surface area, connected to a system of internally branched channels with the source of vacuum. Large number of small vacuum chambers in place allows to minimize leakage of air though pores and openings on the surface of the mouth of weaved flexible container, which increases reliability of holding and reduces energy consumption during the process of handling air-penetrating packaging during its’ filling.
Highlights
In a modern automated packaging production, it is necessary to introduce robotic and mechatronic systems, allowing to fully automate the packaging process, thereby increasing the quality of the process, productivity and environmental friendliness, eliminating the human factor
If the flexible container is made from air-penetrating material, the effectiveness of its gripping, opening and holding during filling is reduced, since significant air leaks occur when the vacuum chambers of a sufficiently large size interact with the material of the flexible container
The dimensions of outer gripping modules 2 of the gripper mechanism are selected in such a way that the length of the working surface of the entire vacuum gripper is equal to the width of the neck of the closed flexible container 6
Summary
In a modern automated packaging production, it is necessary to introduce robotic and mechatronic systems, allowing to fully automate the packaging process, thereby increasing the quality of the process, productivity and environmental friendliness, eliminating the human factor. If the flexible container is made from air-penetrating material, the effectiveness of its gripping, opening and holding during filling is reduced, since significant air leaks occur when the vacuum chambers of a sufficiently large size interact with the material of the flexible container. Existing VGDs, for example, described in [6,7], do not allow to solve this problem
