Abstract

At present, with the increasingly intensified competition in the market, as well as food, beverage, pharmaceutical, and other safety and health requirements of the improvement of three-in-one (Blow / Fill / Seal) equipment to medical equipment from market-oriented, gradually extended to more areas and has become the mainstream of packaging machinery.

1. System Requirements

• May need to manually adjust the parameters in accordance with
• For decision-making with real-time accurate data
• Fieldbus manner of data acquisition and control, industrial control station computer-based data acquisition and control of management, the provision of human-machine interfaces and network services
• Friendly man-machine interface, data at a glance
• Modular structure, easy to extend
• Simple operation, easy maintenance

2. Analysis

Packaging equipment for modular units, we have adopted a "Tablet PC configuration software + HMI + PLC + inverter + Temperature Meter + servo positioning controller" control portfolio, which, flat panel computer monitors the production process, showing the status of work and can be manually adjusted parameters, advanced temperature control, light control, process control, positioning control, frequency control, automation technology, to achieve matching packaging, for sealing, automatic protection features such as failure to achieve stable, safe and reliable high efficiency, the goal of speed to reach bag - filling - sealing, cup system - filling - sealing, blowing - filling - sealing and other purposes of three-in-one packaging.

PPC-L156T fanless design is a Tablet PC, the product is to require low-noise and ultra-clean working environment for an ideal solution for applications. PPC-L156T with two power supplies: an optional battery pack and an AC power supply. PPC-L156T-connected after AC power for charging batteries. Optional rechargeable battery pack more than 60 minutes time, a power outage in case of an accident, can be used as a UPS power supply. PPC-L156T in line with the VESA standard mounting hole through its flexible approach using a variety of installation. Features removable front cover for products such as LCD and touch screen provides a convenient maintenance.

3. System Architecture

Control in the system, the core of control parts of S7-300PLC, through PPC, acquisition systems, sensors, inverter motor, etc. The electrical control part of the system. Powerful S7-300, the control system can be achieved, while the PPC is a Tablet PC fanless design, CPU for embedded Intel ULV Celeron800 MHz / Pentium M 1.1 GHz, the highest support for 1GB of DDRAM1 the Mini PCI slot, 1 CF card slot, a 32-bit PCI slot (optional) 10/100 Base-T or Gigabit Ethernet, USB2.0 interface has two, three COM port, VGA interface, PSII mouth 10M/100M adaptive Ethernet port, and fully meet the requirements of the scene. MCGS own pre-installed software configuration can be achieved and friendly user interface, historical curve, the police and so on.

4. Software Description

Control in the whole process, PLC is part of the core control, PPC main parameter setting interface, graphics, sound and light alarm, such as data query. Running in the system, we set up the parameters, the system automatically run, running through the interface that we can clearly see the status of various parts of the system, parameters, the system can see trends, make timely adjustments in the event of failure can also time when the first repair in time to find where the problem lies, but also in the long run after the statistical data, the system made in the overall analysis.
