Description

Material taking and stacking device based on PLC control Technical Field The invention relates to the technical field of food processing, in particular to a material taking and stacking device based on PLC control. Background The fried dough twist is used as a traditional fried flour food, and the production process generally comprises the steps of dough kneading, tabletting, slitting, twisting and forming, frying, cooling and packaging and the like. With the deep development of food processing mechanization, an automatic dough twist processing machine can efficiently finish continuous forming operation from dough to semi-finished dough twist, and the efficiency of basic procedures is greatly improved. However, the molded semi-finished twist is transferred to frying equipment for curing, and the joining process still highly depends on manual operation in the prior art. Operators have to collect scattered semi-finished products of the fried dough twists at the discharge end of the fried dough twist processing machine in real time, and stack the semi-finished products of the fried dough twists on a tray or a conveying mesh belt in order according to a specific arrangement rule, and then send the semi-finished products of the fried dough twists into the frying machine. The manual mode has the obvious defects that the manual operation speed is difficult to match with the discharging rhythm of the high-speed fried dough twist processing machine, when the discharging speed is increased, semi-finished products are easily accumulated, mutually adhered or deformed to cause the reduction of the product quality, meanwhile, operators need to repeatedly bend down, grab and stack for a long time, the labor intensity is high, the labor intensity is easy to fatigue, the rest is required to be frequently interrupted, and the production efficiency is fluctuated. In addition, the hands directly contact the un-fried green twist, so that the surface of the dough is softened, deformed and oil stain is permeated due to improper body temperature or operation force, the product phase and taste of the final product are affected, the risk of introducing microbial contamination is also present, and potential threat is formed to food safety. More notably, the fried dough twist processing machine and the frying equipment are single systems which are operated independently, a special automatic connecting device is lacked between the two systems, and a semi-finished product often needs to be subjected to intermediate temporary storage in the transferring process, so that the complexity of a production process is increased, the exposure time of the semi-finished product in the air is prolonged, the surface is easy to air dry and crack, and the puffing effect and the crispness after frying are further weakened. Disclosure of Invention Aiming at the situation, in order to overcome the defects of the prior art, the invention provides the material taking and stacking device based on the PLC control, and the problems that in the conventional fried dough twist production, the process that the semi-finished dough twist molded by a dough twist processing machine is transferred to frying equipment, the labor intensity of manual operation is high, the transfer efficiency is low, the semi-finished products are easily accumulated, adhered or deformed, the risk of secondary pollution of microorganisms exists, and the quality and the taste of the final product are affected are effectively solved through the design.
