Vibration removal type automatic unpacking and feeding device

Abstract

The invention discloses an automatic unpacking and loading device for removing residues by vibration. The device comprises a pack carrying machine, a conveying belt, a collector, a cutting mechanism, a pack vibration mechanism and a pack towing mechanism, wherein the pack carrying machine is used for carrying packs onto the conveying belt; the surface of the conveying belt is upwards inclined for conveying the packs; the length directions of the packs are perpendicular to the conveying direction of the conveying belt; a first pack sensor for detecting the packs is arranged on the conveying belt; the collector is arranged below the conveying belt; when the packs enter the front end position of the conveying belt, the cutting mechanism is controlled to cut the middle parts of the lower side edges of the packs; the pack vibration mechanism is positioned at the back end of the conveying belt; when the packs are detected to reach a preset position at the back end of the conveying belt, the packs are vibrated and flapped to accelerate discharge of the residues; when the pack vibration mechanism vibrates and flaps the packs, the pack towing mechanism grabs and tows the packs to advance; and when the residues are emptied, the packs are towed away the conveying belt. The device realizes automatic unpacking, cannot generate the packing bag chip pollution for particles, realizes no-residue falling, and prevents raw material wastes.

Description

technical field [0001] The invention relates to the technical field of unpacking and unloading, in particular to a vibration-residue-removing automatic unpacking and feeding device for industrial production. 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 and smooth all...

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
