ACCUMULATOR POSITION MEASUREMENT
Accumulator type blow molding machines require a position transducer to indicate the accumulator position.
The parison wall thickness pattern can then be programmed with direct reference to the accumulator
stroke of Shot Size.
If the DigiPackⅡis being installed on a continuous extrusion machine please go to the next section.
1-5-10.
INSTALLATION REQUIREMENTS
The position transducer is required to operate in a high temperature and vibration environment. In addition
the transducer must accommodate some mechanical miss-alignment without reduction of life and linearity.
Transducer installation designed to control and adjustment the alignment between the potentiometer and
the accumulator motions. The features are as follows:
1)
An accumulator driven bearing guided structure for the potentiometer drive arm
2)
Mounting provisions for the potentiometer on the same bearing guided structure, provisions for
adjustment to insure parallel motion of the potentiometer guide arm and potentiometer drive rod
3)
And a rod end bearing between the potentiometer drive rod and the potentiometer guide arm
