Minitron - Coil-Winding Feeder Specs

MAIN BENEFITS
  • TOP Quality Standards Goal

is ensured by the highest coil winding quality and repeatability, thanks to BTSR ‘Double Closed Loop’ Technology guaranteeing the most accurate and precise wire tension control.

  • TOP Versatility

 is guaranteed by Fully programmable parameters according to the wire requirements and possibility to dynamically modify the wire control tension according to the operating stage (‘Tension Profiler’ Function).

  • TOP Process Production Efficiency

Thanks to the user-friendly programming options and easy and quick machine setup.

  • TOP Productivity

is guaranteed by the capability to work at the maximum possible process speed.

  • Minimized Labour Costs

is possible thanks to the user-friendly programming options.

  • A wide application range

 is possible thanks to the wide wire tension and diameter range of MINITRON

  • Centralized programming and monitoring

 is possible thanks to MATRIX TOUCH COIL controller which will allow to program and control MINITRON units and monitoring the whole process production status also in graphical form.

DOUBLE CLOSED CONTROL LOOP (BTSR Patent)

MOTOR TORQUE (BTSR Patent)

1st closed loop

Total Input Controls

Operated by the motor control force (Torque). Detects and adjust any input wire tension variation caused by:

• Input tension variation (full/empty feeding bobbin)

• Input wire entanglement

LWA Length of Wire Absorbed (BTSR Patent)

2nd closed loop

Total Output Controls Operated by means of multiple motor controls, Speed/Wire consumption.

Detects and monitor:

• Any dimensional variation of coil formers.

• A wrong wire dimension (diameter/AWG).

• Accumulation of dirtiness inside the wire guide

• Damage of the wire guide.

• Any mechanical variation or friction on the contact points after the tension feeder device (Minitron - Megatron - Gigatron).

• Wire passing through the wire guides with different angles and frictions (wrong thread-up).

CONSTANT TENSION VALUE GUARANTEED

Output Wire Tension (LIGHT BLUE color) is kept constant at the set value, despite of input wire feeding tension variations (RED color) and/or wire speed variations (GREEN color) during the working process.

MATRIX TOUCH COIL TERMINAL

Centralized programming and monitoring is possible thanks to MATRIX TOUCH COIL controller which will allow you to program and control MINITRON - MEGATRON - GIGATRON units and monitoring the whole process production status also in graphical form.
