Vibrational residue removal type automatic unpacking and unloading method

Abstract

The invention discloses a vibrational residue removal type automatic unpacking and unloading method. The method comprises the following steps that material bags are moved onto a conveying belt; the surface of the conveying belt slopes downwards, and the conveying belt is used for conveying the material bags to a bag cutting bin located at the rear end of the conveying belt; the bag cutting bin isvertically arranged, and an opening is formed at the bottom of the bag cutting bin; after the material bags enter the bag cutting bin, a cutting mechanism, mounted close to the rear end of the conveying belt and located below the bag cutting bin, penetrates through the opening at the bottom of the bag cutting bin, and the material bags are cut open; after cutting is completed, a bag vibrating mechanism located on the outer side of the bag cutting bin functions, and the material bags are vibrated and patted to promote discharging of residue; and when the material bags are vibrated and patted bythe bag vibrating mechanism, the material bags are caught and dragged upwards by a bag dragging mechanism, and the material bags are dragged away from the conveying belt when the residue is emptied.By means of the vibrational residue removal type automatic unpacking and unloading method, automatic unpacking is achieved; packaging bag scrap pollution is not generated to a particle material; and non-residual blanking is achieved, and waste of raw materials is prevented.

Description

[0001] This application is a divisional application with application number 201710037245.5, application date January 13, 2017, and the title of the invention "a method for automatic unpacking and unloading with vibration and residue removal". technical field [0002] The invention relates to the technical field of unpacking and unloading, in particular to an automatic unpacking and unpacking and unpacking method for industrial production with vibration and residue removal. Background technique [0003] 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 uns...

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

[0005] 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 fall into the folds and corners of the material bag. The problem of residual material

[0006] It can be seen that the automatic unpacking and unloading device in the prior art is prone 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
