Automatic unpacking and feeding method based on vibration removal method

Abstract

The invention discloses an automatic unpacking and feeding method based on vibration removal of residual material, which comprises the following steps: moving the material bag to the conveyor belt; the surface of the conveyor belt is inclined upward, and a device for detecting the material bag The first material bag sensor; set the collector under the transmission belt, collect the material before loading; the material bag enters the front end of the conveyor belt, and the middle part of the lower side of the material bag is cut by the cutting mechanism installed near the front end of the conveyor belt. Carry out cutting; the cut material bag continues to be conveyed, when it is detected that the material bag reaches the predetermined position at the rear end of the conveyor belt, the vibration bag mechanism located at the rear end of the conveyor belt works, vibrates and beats the material bag to promote the discharge of residual materials; in the vibration bag mechanism While vibrating and beating the bale, the dragging mechanism grabs the bale and drags it forward, pulling the bale off the conveyor belt as the remnant is emptied. The invention realizes automatic unpacking, does not produce packaging bag debris pollution to granular materials; realizes no residual blanking, and prevents waste of raw materials.

Description

technical field [0001] The invention relates to the technical field of unpacking and unloading, in particular to an automatic unpacking and loading method for industrial production based on vibration and residue removal. Background technique [0002] The main raw material for the production of plastics (such as biaxially oriented film BOPP) is polymer particle PP material, which is generally packed and transported in woven bags. At present, most of the feeding of granular materials in China is done manually, and there are many disadvantages in manual feeding. First of all, manual feeding seriously reduces the degree of automation of the process, and manual unpacking is labor-intensive and prone to fatigue, resulting in unstable feeding speed, which is prone to problems that the manual speed cannot keep up with supporting equipment; secondly, material bag feeding and cutting is a heavy task. It is tedious manual labor, and it is difficult for manual feeding to be efficient a...

AI Technical Summary

Problems solved by technology

For the granular material package, Italy has developed an automatic feeding and cutting system for the polymer particle material package, which uses a manipulator to move the material package to a special cutter head bag breaker, then puts the material bag down, and the material bag falls to the cutter head This system is easy to break the woven bag and cause the problem that the woven bag debris pollutes the raw material

Similarly, some domestic automatic unpacking devices also have this problem, such as Chinese patent CN2013102767140 and patent CN201510116184, both use saw blades to destructively unpack bags, which is prone to bag debris

[0004] Chinese patent CN2015201899359 has improved this problem. When the bag is broken, the bag debris will not fall into the material pool with the material, but it still has the incomplete whereabouts of the material in the material bag, and it is easy to be at the folds and corners of the material bag. The problem of residual material

[0005] It can be seen that the automatic unpacking and feeding device in the prior art is easy to produce packaging bag debris, and it is easy to mix into the material, and the incomplete whereabouts of the material causes the problem of waste of residual material
