In the pharmaceutical, food, medical device, cosmetic, health product and handicraft industries, the equipment used for aluminum-plastic and aluminum-sealed packaging of tablets, capsules, soft capsules, candies and other items is today's protagonist that meets "GMP" requirements: blister packaging machine.
Application of Hexin Solution
Hexin has developed a pulse control solution for the CTH200 main controller for the blister packaging machine market, which features stability, reliability, precision, and speed.
Hexin on-site: Blister Packaging Machine
Machine Description: Flat-panel blister packaging machine
A blister packaging machine is a machine that uses transparent plastic film or sheet to form blister packs and seals the product between the blister pack and the base plate using methods such as heat sealing and bonding.
① Process flow of flat-plate blister pack machine:
The forming film is heated and softened by a flat heating device. In the flat forming device, compressed air is used to blow the softened film into a blister. The filling device fills the packaged goods into the blister and then sends it to the flat sealing device. Under appropriate temperature and pressure, the covering film and the forming film are sealed together. The batch number is then printed and the fold line is pressed out by the printing and stamping device. Finally, the punching device punches and cuts the product into product plates of the specified size.
②Key control points:
★ The entire motion sequence is determined by the encoder angle, requiring precise timing of each action;
★ Equipped with a calibration mode, it requires deceleration before reaching the color mark to prevent excessive deceleration from damaging the film.
Hexin - Blister Packaging Machine Control Solution Configuration
Hexin provides a complete control system consisting of PLC, servo motor, and HMI to meet the control requirements of blister packaging machines.
Solution Analysis
The blister pack machine control system uses the Hexin CTH200 series 40-point universal H226IL as the main controller, and expands to the SM231 temperature module to judge the temperature of three heating plates; the film advance is achieved by pulse control of an A3S servo drive system; it is stable, reliable, accurate and fast.
Touch screen system: The system adopts the Hexin TP series TP07i Ethernet HMI, which communicates with the PLC via EtherNET. It can monitor the current production speed, heating plate temperature, and set the timing of actions such as blowing, forming, and punching.
The flat-panel blister packaging machine controlled by Hexin PLC has powerful functions and an intelligent operating platform, enabling packaging technology for multiple product types and achieving coordination, stability, energy saving, and high efficiency at each workstation.
