Yaskawa Servo Controller Streamlines Extrusion Die Adjustments

One of our clients needed a solution for automatically adjusting his horizontal extrusion die. The die controls the thickness of a plastic web about 72 inches wide.

Previously, the 72 bolts across the top of the die were adjusted by hand by an operator. The worker would compare the readings on a nuclear micrometer to what the set point was. This was labor intensive and required a lot of the operator’s attention, time he should have been dedicating to watching the machine and its operation.

Servo controllers, motors and Modbus solved a die adjustment problem on this extrusion machine.

Servo controllers, motors and Modbus solved a die adjustment problem on this extrusion machine.

Our solution was to incorporate a Yaskawa multi-axis servo controller with four servo amplifiers and motors and Modbus communication to interface with their micrometer.

A brief explanation: Two motors are mounted on two “heads.” Each head consists of:

  • A position motor with a gear reducer that travels on a linear gear across the die
  • And, an adjusting motor with a socket mounted to the motor shaft that pneumatically lowers down on a bolt to adjust it.

Each head is taught the position of the first bolt by moving it manually to that position. The distance between each bolt is inputted into the system through the Parker HMI. Then each head travels across the die, learning the positions of every bolt and the rotational position of each bolt head. In case of vibrations or other external influences to the bolts, the system has the ability to relearn on the fly the rotational position of any bolt.

The micrometer will message the servo controller via Modbus when a portion of the web is out of tolerance. The servo controller is told which bolt is causing the error and by how much. The “head” closest to the offending bolt will move to a bolt 3 bolts away. Then, alternating between bolts on either side of the offender, the head start adjusting the bolts. The outside bolts receive minor adjustments working up to a full adjustment on the center (and offending) bolt.

Result; the operator can manage the machine and not have to micromanage a bunch of bolts.

Application Note: Going From DC Motors to a Synchronized System of AC Motors and Drives

Overview:  At one company, there is what they call a brine box. There is a saltwater tank setup that slows an electric motor saw. Within this setup, they use three DC motors. They decided they would like to change the DC motors to AC motors. In addition to changing from DC to AC, they would like to implement speed control between the motors including the ability to decelerate the motors at the same time, and at the same rate.

The Solution: We selected the AC motors to match the required speed and torque needed for the application. This information was obtained by analyzing the load conditions and from the specifications at which the DC motors were running the application. For speed control, the simple solution was to daisy chain Yaskawa drives. This allowed the drives to communicate with each other, as well as synchronize their deceleration.

The Results:  The AC motors can be rated to give the same performance, or higher performance, as the DC motors.The AC drives can provide for controlled acceleration and deceleration rates. Connection between the drives allows for the synchronization of the acceleration and deceleration rates.The Yaskawa drives have the ability for the parameter setting to be extracted. This would make programming the drives to be easier by setting the parameters in one, and just copying the parameters from that one to the other two.
