Up-to-date complete control system for blow moulding machines

Overview:
  • IPC-Control based on Windows CE.NET
  • PC without fan and harddisk
  • Beckhoff TwinCAT control softwrae with hard realtime (15μs jitter, time base 1ms)
  • PLC software, technology software and visualisation on one PC
  • Remote diagnostics via VPN
  • TFT operator panel with touchscreen
  • Data saving by flash memory (compactflash, USB-stick) or network
 
Conception of the control:
  • PanelPC
  • EtherCAT fieldbus
  • Distance for I/O up to 100m (between 2 stations)
  • USB- and LAN interfaces
  • Optional additional fieldbus (Profibus, CAN, Sercos, ...)

 Operator panel:

  • Panel PC - Industrial-PC intergated in the panel
  • 12'' TFT display
  • Touchscreen
  • 12 function keys for screen selection
  • Numerical keyboard, cursor block
  • 10 PLC-keys with LED for activation of special functions
  • EtherCAT fieldbus 100MBit
  • Ethernet 100/1000 MBit
  • Installation in the wall of the switch board or panel version
Advantage at a glance:
  • Control system for combine PLC-, motion control- and visualisation functions
  • Function independent hardware, all software modules are installed in one CPU
  • Industrial PC with PLC chracteristics, without fan and rotating memory disk, fast booting, real time clock, exchange of programs by storage cards, remanent memory and operation without UPS
  • Efficient CPU; Intel Celeron M, 1 GHZ Taktfrequenz
  • Operation system of the latest generation: Microsoft Windows CE.NET
  • Ethernet, EtherCAT, COM1 and USB already installed in the basic version
  • Support of the most fieldbus systems like Profibus, CANOpen, DeveiceNET, SERCOS and Lightbus
  • Ability to fit for WEB-server or FTP-server for internet-/intranet applications
  • Via analog modem conected to the serial interface PLC software changes and Remote Desctop (screen 1 to 1 from the remote computer visible) can be done.
  • Low heat and low power consumption
  • Small measurements of the system require little space within the switch board or terminal box

Function overview:
  • Temperature control for extruder and head, 2-and 3 point controller, self optimizing
  • Wall thickness control up to 10 channels (selectively 100, 200 or 400 setpoints)
  • Accumulator head operation (constant or profiled, 3 heads)
  • Extruder speed control, synchronized adjustment when operation more than 1 extruder
  • Parison lenght control in case of continuous extrusion
  • Filling level control and die adjustment during accumulator head operation
  • Distance cams for clamping unit and blowpin
  • Closed loop motion control for hydraulic axis
  • Blow mould open / close
  • Blowpin movement
  • Blow mould movement
  • Motion control for electrical axis
  • Display of melt temperature, melt pressure, extruder speed, extruder torque or current
  • Monitoring of process parameters as e.g. melt temperature, melt pressure, Timers, ect.
  • Sequence control of the machine - presections, timers and counters are shown on the display
  • Display of blowing devolution in a diagram
  • Diagnostics, error messages in plain text with timestamp
  • Operator protocal: Each change of value by the user is logged in a file (wtih following information: timestamp, user, user-level, old value, new value).
  • Process data monitoring: important process data (e.g. cycle time, blowing time, extruder rpm, melt pressure, melt temperature, other temperatures, etc.) are displayed in a chart and logged in a file (text-, XML-File or connection to SQL-server) for each cycle.
  • Integrated scope functionality of motion actual- and setpoint- values
  • Configurable access levels: The access of each input control (input fileds, preselections. timers. check boxes, buttons, ...) can be changed individual on screen.
  • Limit values for numeric input can be changed individual on screen.
  • Saving of setting parameters internal, on USB-stick or network. The setting paramaters can be organized in different groups like wallthickness-, temperature or movement values.
  • Language reversal for up t 8 languages at the same time. (asia character sets are supported)
  • Access control via PIN-code, optional fingerprint. 3 access level, 1 administrator
  • Hardcopy function: One or all screen pages can be stored on USB-stick or network.
  • Online help: At each page the help button displays the help page for this screen in the browser.
  • The complete user manual is deposited in HTML-files on the system.
