Automatic unpacking and feeding method

Abstract

The invention discloses an automatic unpacking and feeding method, which automatically transports a packing bag through a packing conveyor and transports the packing bag to a discharging mechanism. The unloading mechanism automatically cuts and unpacks the packages conveyed to it, hangs the packages, lowers and empties the packages to realize automatic unloading; Aggregate feeding mechanism is used to receive the discharged materials and collect and transport them to realize automatic feeding. The invention realizes automatic unpacking, unloading and feeding, and does not produce packaging bagdebris pollution to the granular material. No residual blanking is realized, and the waste of raw materials is prevented.

Description

[0001] This application is a divisional application with the application number 201611041089.1, the application date of November 22, 2016, and the title of the invention "A Method for Automatic Unpacking and Feeding". technical field [0002] The invention relates to the technical field of automatic feeding, in particular to an automatic unpacking and feeding method for industrial production. 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 unstable feeding speed, which is prone to problems that the manual speed cannot keep ...

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 CN 2015103809614 and patent CN 2015103540947, both use saw blades to destructively unpack bags, which is prone to bag debris

[0005] Chinese patent CN2015108873053 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 in the folds and corners of the material bag. The problem of residual material

[0006] It can be seen that the automatic unpacking and feeding device in the prior art often produces packaging bag debris, which is easily mixed into the material, and the incomplete whereabouts of the material causes the problem of waste of residual material
