The J141-215
DigiPack
Ⅲ
is a user friendly, high performance 200 Point Digital Blow Molding Parison
Wall Thickness controller producing lighter, stronger containers at increased production rates.
A properly installed and intelligently used system will deliver higher operating efficiency from your blow
molding machine as a result of faster molding cycles, shorter change over times and reduced scrap.
The DigiPack
Ⅲ
adjusts the parison wall thickness by controlling the core position with the core actuator.
The core position can be finely set up to 200 points maximum.
For an accumulator type blow molding machine, set the target core position with reference to the accumu-
lator position. For a continuous blow molding machine, set the target core position based on time.
The core position control system with the above setting consists of four main components: DigiPack
Ⅲ
controller, servo valve, actuator for core and feedback detector for accumulator. The function of each
component is as follows.
Operator using DigiPack
Ⅲ
to set the core position (core die gap opening / closing amount) required
to obtain a product with the desired wall thickness (usually constant wall thickness). In addition, it
outputs a flow (spool position) command to the servo valve so that the core follows the set core
position.
DigiPack
Ⅲ
also functions as a digital interface with the PLC controller of the blow molding machine
and provides information such as the end of the program and the point status of sequential programs.
The servo valve adjusts the flow rate to the core actuator according to the flow (spool position) com-
mand from DigiPack
Ⅲ
.
The actuator for the core, the core is fixed to the rod, and the rod (core) moves according to the flow
rate adjusted by the servo valve. Moving the core changes the gap through which the parison passes
and controls the wall thickness of the parison.
