Lanfranchi preform loaders couple perfectly with blow moulding machine or injection presses.
They guarantee the high efficiency of lines dedicated to preforms.
The need to reduce the costs of packaging has led now, especially in the field of mineral water, to a reduction in weight of the body of preforms and a consequent reduction in thickness of the neck ring.
Reduced bottle neck thickness with normal processing methods could cause damage to the container which would cause reduced efficiency of the line in case of jamming or negative image, if the damaged container was placed on the market.
To To guarantee the absolute integrity of preforms in the blow moulding machine feeding system, there must not be any changes in height, neither up nor down, of more than 100 mm. This principle applied to the design has allowed Lanfranchi to build SOFT-TIP, the case loading system that guarantees the absolute integrity of preforms, preserving the high efficiency of downstream machines and thereby reducing production scraps.
The working sequence of SOFT-TIP is the following:
The case loader with manual feeding features solid construction and comes in two versions:
Both versions fulfil CE safety standards and include an operator control panel with PLC for the automatic control of the unloading cycle.
A preform containment damper with gradual opening and closing makes it possible to avoid damaging the preforms during the loading phase.
Lanfranchi has developed a completely automatic solution for the management of full or empty preform boxes in highly automated blow moulding systems; this solution includes chain conveyor belts and automatic case stacking and destacking units.
