In recent years, with the substantial growth of the production, sales and export of the nail coil, especially the market demand for hot-dip galvanized nails is increasingly strong, many manufacturers continue to expand production, in order to meet the increasing demand of the market. As an automatic welding equipment, nailing machine is an indispensable part of nailing production process. High speed nailing machine is a popular nailing machine, which can not only meet the increasing demand of nailing production, but also greatly improve the efficiency of nailing production. First of all, the high-speed nailing machine through the vibration plate of the vibration motor and blow valve, the loose nails in order to arrange on the track. When the track is full of nails, the vibration motor and the blow valve stop working. Secondly, after the nail enters the track, with the main motor running, the nail plate sucks the nail on the track to the pad. After the acquisition of welding signals, PLC immediately output welding instructions, the nail and two copper-plated wire welding into wire row nails. Wire row nails by automatic oil immersion rust prevention, drying and counting mechanism automatically rolled into a disc. Finally, according to the set number of each roll automatically cut, the finished product by the operator fixed with a rubber band can be packed into the box. If there is a lack of nails on the track or in the welding pad during operation, immediately stop the equipment and output the alarm lamp, and the fault cause will be displayed by the touch screen. The system uses Hollysys PLC as the control core. According to the requirements of input and output points, the system only needs to configure a CPU module LM3106 that integrates 14 points of switching input and 10 points of transistor output. Through its own RS-232 communication port, PLC realized the communication with the touch screen. PLC mainly collects proximity switch, photoelectric switch and other data, according to the control process requirements, according to the pre-prepared program to control the frequency converter, welding power supply, pneumatic valve and other equipment, to realize the automatic control of the nail rolling machine. The whole system is mainly composed of feeding, welding, finished products, fault alarm processing, display and so on. The feeding part includes a vibration plate and a nail feeding track to complete the supply of nails during welding. The welding part is the core part of the system, which completes the process from loose stitching to row stitching. The main part of the finished product counts, packaging and other processing. When the PLC collects the fault signal, the alarm signal is sent out in time. The touch screen can not only display the speed, fault, operation and other information in real time, but also complete the parameter setting of each link. High speed nailing machine control equipment selection and HOLLiAS? LM series PLC, with its high-speed arithmetic processing function, to achieve the nail welding, nail row accurate count, complete the production of the nail roll, improve the anti-interference ability of the system and processing speed, economic and social benefits are very considerable.
