Abstract
A unit for forming packs of products for a packaging machine comprises at least three feed surfaces (3, 4, 5) for layers of products (2) and a receiving station (6) for the layers of products (2). The receiving station (6) comprises an elevator (7), mobile only between a position for loading the products (2) and a position for releasing the products (2), to transfer the layers of products (2) to a packaging machine (8). The three feed surfaces (3, 4, 5) comprise synchronization means so that they simultaneously release the respective layers of products (2) onto the elevator (7).
Claims21
A unit for forming packs of products for a packaging machine, comprising a plurality of feed surfaces for layers of products and a receiving station for the layers of products, the receiving station comprising an elevator for transferring the layers of products to a packaging machine, the elevator being mobile only between a position for loading the products and a higher position for releasing the products, wherein there are three feed surfaces, respectively a first, second and third feed surface positioned on top of one another and comprising synchronization means for controlling the speed of the feed surfaces and moving the products on each feed surface at predetermined speeds so that the products reach ends of the respective feed surfaces at the same moment and the respective layers of products are simultaneously released onto the elevator.
A method for forming packs of products to be transferred to a packaging machine, comprising the steps of alternately feeding one after another a first, second and third feed surface with respective layers of products, feeding said layers of products from the first feed surface onto an elevator located in a loading position, further comprising the steps of controlling the speed of the feed surfaces, synchronizing movement of the feed surfaces, moving the products on each feed surface at predetermined speeds so that the products reach the end of the respective feed surfaces at the same moment, releasing simultaneously the layers of products onto the elevator.
A unit for forming packs of products for a packaging machine, comprising a plurality of feed surfaces for layers of products and a receiving station for the layers of products, the receiving station comprising an elevator for transferring the layers of products to a packaging machine, the elevator being mobile only between a position for loading the products and a position for releasing the products, wherein there are three feed surfaces, respectively a first, second and third feed surface positioned on top of one another and comprising synchronization means so that they simultaneously release the respective layers of products onto the elevator, and wherein a first and a second containment wall, parallel with one another, are located at the receiving station for providing lateral support for the layers of products and for laterally compressing and compacting the layers of products, by moving the first and the second wall towards one another.
