Container cleaning-drying and filling-sealing interlocking machine set control system

Abstract

The invention relates to a container cleaning-drying and filling-sealing interlocking machine set control system, which comprises a detection element, a control element, an actuator element and an operating element, wherein the detection element is a non-electricity measurement sensor; the control element is a programmable logic controller (PLC); the operating element is a touch screen; the programmable logic controller (PLC) comprises a central processing unit (CPU) and an extension unit; the extension unit comprises an output extension unit and a temperature control unit; the temperature control unit is connected with the CPU; the CPU of the programmable logic controller (PLC) is connected with the non-electricity measurement sensor, the actuator element and the touch screen respectively; and the temperature control unit is sequentially connected with the actuator element and the non-electricity measurement sensor to form a closed loop structure. The scheme ensures low production cost, and meets the requirements of electronic tags and electronic records of good manufacturing practice (GMP) as well as the requirements on energy saving, emission reduction and high efficiency.

Description

technical field [0001] The invention relates to a control system, in particular to a container washing, drying, filling and rolling unit control system. Background technique [0002] There is a need to improve the design and wiring of the current electronic control system. The oral liquid glass bottle washing, drying, filling and rolling linkage unit consists of an intermittent automatic cleaning machine, a tunnel-type far-infrared sterilizing dryer, a plunger pump filling machine, and a multi-head 3 The knife capping machine consists of four machines, and the machines are connected by mesh belt and screw conveyor. The existing electric control system consists of three independent electric control parts (three electric control cabinets). [0003] The existing electronic control system has many discrete components, many types of power supplies, many old-fashioned devices, many electrical cabinets, many indicator lights, and many switches. Of course, there will be more connec...

AI Technical Summary

Problems solved by technology

There are many discrete components, the electrical performance consistency of the electric control system is poor, and the old-fashioned devices are bulky and require a relatively large space. Therefore, the existing electric control system uses three electric control cabinets, and the cost is very high.

[0004] In the electronic control system of the sterilizing dryer, the electric heater protection method uses a fuse to protect multiple electric heaters. If a single electric heater overcurrent occurs, the fuse will not respond; between the output of the frequency converter and the motor, Adding the AC contact link is a hidden trouble for the inverter; adding a relay contact link between the output of the temperature controller and the solid-state relay, the proportional integration differentiation (PID) function is destroyed

[0005] The existing electronic control system has a recorder, but it lacks the function of electronic signature, let alone the function of displaying real-time working conditions, and it does not meet the requirements of the GMP standard (Good Manufacturing Practice, pharmaceutical production management regulations) as recorded in Article 169 of Chapter 8 The "Dual Power" standard must have electronic signature and electronic record functions
