PET Preform Conveyors
|
From early in the life of two stage PET bottle production, PCE has been involved with the design and manufacture of conveyors to take the preforms from the out feed conveyor of the injection moulding machine and discharge to one, two or more boxes. The standard range incorporates:
- Soft face food contact approved continuous welded belting.
- Tracking strip to prevent belt wander.
- Belt driven incline conveyor drive for smooth drive.
- Covered incline conveyor to prevent contamination.
- Fabricated steel frame and stand for durability.
- Shot counting as standard.
- Standard 2 & 3-box configurations.
- Standard designs for most HUSKY moulding machines.
- Configuration for other moulding machine suppliers available.

Softdrop Option
 |
For certain markets, potential damage to the preform is critical. For these applications, PCE can offer the Softdrop option. Here the preforms are delivered to the bottom of the box minimising the drop heights.
|
Weigh Counting
|
As margins are eroded, the need for accurate stock control is ever more pressing. Instead of counting preforms by multiplying the number of cavities by the number of machine cycles, PCE can offer a more accurate counting method.
By batch weigh counting the preforms using Mettler-Toledo technology just prior to entering the box, the number per box can be individually set. The chance of preforms being taken from the line and not accounted for is virtually eliminated. |
Box Agitators
 |
By agitating the box during filling, many more preforms can be packaged. From customer data >20% of additional preforms per box can be achieved (depending on perform shape and colour).
Operation is smooth and quiet due to the electric drive, and eliminates the need for manual smoothing of the mound at the top of the box.
Shake duration, interval between shakes and speed can all be adjusted and a light curtain protects the operator. |
