90 Degree infeed
Product infeed is at 90 degree with respect to the direction of translation of the layer. This type of palletiser may well be considered the most traditional of all, in that it is based on a commonly used method for layer forming and handling. These palletisers are defined 90 degree infeed palletisers because the products arrives perpendicularly with respect to the direction of layer translation, that is, with respect to the direction of movement of the pusher that transfers the layer of products onto the pallet. Palletisers with 90degree infeeds are generally smaller sized as compared to in-line palletisers.
In-line palletisers with low and high level infeed Product infeed and layer forming take place along the same direction of movement. This series comprises some of the fastest machines in the world and represents the ideal choice for various high-end applications. product infeed and layer forming take place along the same direction of move ment. Unlike 90 degree palletisers, there is no downtime during the layer forming cycle, so the maximum machine speed is generally higher. High and low level infeed: how to choose? Choosing the type of pallet management, either high or low level, may be based on many variables. Without presuming to provide a definitive decision-making tool, the main features and advantages of the two alternatives are illustrated here following.
High level: high level infeed machines with
mobile pallet allow for greater productivity. Layer
forming and, therefore, the final part of the route
followed by the products, takes place overhead,
leaving free passage areas before the palletiser.
This type of machine layout allows for superior
optimisation of ground space.
Low level: low level palletisers are usually more accessible than high level palletisers. All man-machine interactions, for maintenance or any other activity on board the machine, are facilitated by the fact that the machine is at ground level. This also ensures better machine visibility on behalf of the operators, who do not have to change level to inspect the machine during the normal operating cycle.
Robot Palletisers have been evolving rapidly over the last few years. Robots have traditionally offered a flexible solution for low speed production lines. However, current models with 450Kg payloads have enabled full layer picks on most products allowing a Robotic Palletiser to match production speeds in many more varied industries. There are now many successful applications within the Food, Tissue & Drink sectors to name only a few.

The palletising process includes various stages, each of which is indispensable to obtain a pallet on which the product is positioned according to specific requirements:
>Pick-up and deposit
Metering the packages Package metering is used to space and count the products (boxes, bundles, loose products, etc.) to be palletised. The items to be palletised move towards the palletiser from an accumulation area along a system of conveyors that leaves an appropriate space between one item and another and subsequently makes it possible to count the items. Products may be handled singly (product by product) or in batches. The latter solution contributes to a significant increase in productivity and reduces the speed of forward movement of the product; on the other hand, working by rows of products does not permit positioning each row specifically. The heart of the metering section consists in a system with two (or three) belt conveyor segments that run at different speeds. There are 2 different package metering systems designed based on the stability of the product being handled.
Double metering belt with 1 motor
Fixed speed ratio between the two belts (usually 1:2) to create a space equal to the size of the package. This system is usually used to count packages and leave the space needed for rotation.
Double metering belt with 2 motors
Variable speed ratio between the two belts, to optimise system performance. This system is used to count packages and leave the space needed for rotation. The system creates the minimum space needed, based on the palletising pattern (ex. for non-rotated objects, the space required is less than that needed for objects that have to be rotated, thereby allowing higher speeds).
