An automatic unpacking and unloading method

Abstract

The invention discloses an automatic unpacking and unloading method. A conveyor belt is used to convey the material package, and a material package sensor for detecting the material package and a magnetic needle head ligand matched with the head of the magnetic needle are arranged on it; the material package is transported When reaching the predetermined position, a cutting mechanism is used to cut and unpack the material bag; a hanging bag mechanism is arranged above the conveyor belt, and a magnetic needle ejection mechanism and a magnetic needle tail ligand matching with the magnetic needle tail are sequentially arranged on it The magnetic needle is located in the magnetic needle ejection mechanism in the initial state, and in the process of transferring the material bag after cutting and unpacking, after the position of the material bag is detected by the material bag sensor, the magnetic needle is ejected from the magnetic needle ejection mechanism to the material bag, The head of the magnetic needle cooperates with the ligand of the magnetic needle head; then the magnetic needle is sucked up by the tail ligand of the magnetic needle on the bag hanging mechanism, so as to realize the lifting of the material bag. 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 automatic feeding, in particular to an automatic unpacking and unloading 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 plas...

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
