BC6 Control System for Paper Cutter Gauge setting control

Gauge setting BC6 control system has been designed for upgrading of paper-cutters of the older types, which are not equipped with electronic control of the gauge position. The BC6 has been used successfully for upgrading the elder types of paper cutters manufactured by ADAST company, Czech Republic - for instance the following models: 80r10, 80r12, 115r10, 115r12, SEY115, SEY132. In general, the BC6 is applicable for upgrading the paper cutters with motor-driven gauge moving, controlled with classical three-phase asynchronous motors. The upgrading can be taken into consideration in case of paper cutters in good general conditions and with the cutting circuit working perfectly. The system BC6 control unit is equipped with MOTOROLA® Inc. microcontroller.

BC6 Functions

  • The initial position setting
    It sets the absolute starting position at the first IRC index after having left the rear-end switch.
  • Drive into the position
    It drives to the position set.
  • Strips cutting
    Setting of the strip width and number, drive of the gauge to the position of the strip cut, and waiting for the cut after that repeatedly. Setting of as many as two widths of the strips (and setting of the eventual cut-out width - the third strip) and of the number of strip groups drive of the gauge to the strip cut position alternatively by the widths defined, and waiting for the cut after that repeatedly.
  • Drive into front position
    Shift of the material from any position to the front position (according to the clamp-plate position).
  • Stop
    Stops the function currently in progress.
  • Manual slow drive forward
    Slow drive of the gauge forward.
  • Manual fast drive forward
    Fast drive of the gauge forward.
  • Manual fast drive backward
    Fast drive of the gauge backward.
  • Counting the cuts since putting the machine into operation and displaying the number of cuts performed
  • Service function of BC6 - parameters setting during the installation
    • initial position 800, 1150 or 1320 mm,
    • screw 10, 12 or 20 mm per turn.

BC6 package and delivery

  • The electronic control system BC6 is delivered within a metallic box with connectors for connecting input signals, output signals, and power supply - 12 to 20V AC, 5VA. The connectors are completed with their counterpieces through which all machine input and output signals are connected (including IRC inputs and inverter of the gauge drive motor control signal outputs). The box is mounted into the paper cutter.
  • The BC6 system is provided with a washable keyboard with 21 keys.
  • The BP6 system display consists of a six-digit with seven-segment LED display of a 20 mm character height.
  • BC6 delivery kit includes accompanying documentation of BC6 system describing the connection of machine signals, IRC signals, and inverter control signals. Also "BC6 User's and Installation manual" is included.
  • Upon the customer's order the complete kit for upgrading of the machine can be delivered, including inverter, incremental position counter (IRC), contactors, etc.
