APPLICATIONS
ROTARY PACKAGE SEALING APPLICATION
Application Solution: The IIS 11/2 axis DeltaMax controller is ideally suited for this master slave application. A servo motor is connected to the seal/cut drum via a precision gearbox. A line encoder is connected to the conveyor system to sense the speed and position of the conveyor. A product sensor is positioned to detect the incoming product and to compensate for slight product pitch variations.
An application program for the DeltaMax controller was developed using the MacroPro II PC software to create the following sequence:
- The seal/cut drum is positioned so the knives are horizontal and clear of the plastic web.
- The conveyor starts running and product is fed onto the second conveyor.
- When the sensor detects a product, the servo driving the cutter/sealer drum synchronizes to the web, cuts and seals the leading edge of the first product.
- An electronic cam in the DeltaMax controller, driven by the line encoder, is used to control the motion of the cutter/sealer drum to create a seal and cut between each product.
- The pitch of the cutter/sealer is electronically adjusted, using the product sensor, to compensate for product spacing.
- If the product flow terminates or a jam is detected the cutter/sealer drum is positioned horizontally and the heater controls are turned off.
Additional Application Features:
- Touch screen operator interface for batch count, parameter entry, diagnostics and error messages.
- Control of the conveyor prime mover motor.
- Control of heaters for the cutter/sealer drum and side seal rollers.
Other Industry Applications:
- Rotary Cutoff
- Perforating
- Rotary printing
