A method for automatic unpacking and feeding

Abstract

The invention discloses an automatic unpacking and loading method. The method applies the bag conveyor to convey the material bag, and feed the bag to the unloading mechanism. The unloading mechanism automatically cuts and unpacks the bags conveyed upon it, hoists up the bags, lowers down the bags to empty the bags to achieve the automatic material unloading. Material gathering and conveying mechanisms are used to accept the unloaded material and collect and convey the unloaded materials to achieve the material loading. The method achieves the automatic unpacking, unloading and loading with no contamination caused by broken packing bag pieces to the particle materials thus achieving the non-residue material unloading, and preventing the squandering of material.

Description

technical field [0001] The invention relates to the technical field of automatic feeding, in particular to an automatic unpacking and feeding method 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-weather. Therefore, the plasti...

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 CN2015103809614 and patent CN2015103540947, both use saw blades to destructively unpack bags, which is prone to bag debris

[0004] 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 fall into 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 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
