The automatic cartoning machine integrates optics, mechanics, electricity and gas, and is controlled by computer. It is suitable for automatic mechanical packing of plate and bottle-shaped articles such as pharmaceuticals, food and health products. Automatic delivery of items, folding and transmission of instructions, carton forming and transmission, loading of articles and instructions into cartons, carton tongue packaging at both ends and other processes, and automatic rejection of non-conforming products. According to the object of packing, the cartoning machine can be divided into plate-type automatic cartoning machine (the cartoning object is mostly the medicine plate packed with bubble cap) and bottle-type automatic cartoning machine (the cartoning object is mostly the medicine bottle). The two machines have the same technological process and are mainly used in the medicine industry cartoning machine. At present, the speed of cartoning machine is generally 80-100 boards/min PLC.
