Abstract

Abstract An improved device for dispensing volumetric batches of incoherent products, particularly for high speed packaging machines, comprising a dispensing drum with horizontal axis of rotation, having peripherally distributed batching recesses, a product feed hopper associated with the dispensing drum, means for the entrainment of the packaging band from which the envelopes for the product batches are formed and which is maintained in contact with the surface of the dispensing drum without slipping on it.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 209 words
Device for dispensing volumetric batches of incoherent material comprising a horizontally arranged material dispensing cylinder which is rotatable about its horizontal axis and is provided with a plurality of radially outwardly open pockets, a hopper for the material positioned at the top of the dispensing cylinder and adapted to feed by gravity incoherent material into the pockets as the cylinder rotates, a roller idly supported adjacent and downstream of said hopper and adapted to deviate a strip of packaging material around the dispensing cylinder in the direction of rotation of the latter so as to partially wrap said cylinder, and means for driving the strip of packaging material including a pair of counterrotating entraining rollers through which the strip passes and provided with complementary recesses, wherein according to the improvement said entraining rollers have their rotation axes lying in a vertical plane and their contact line lying in a horizontal plane tangential to the lower point of the dispensing cylinder so that the strip defines a horizontal run extending from the dispensing cylinder to said entraining rollers for receiving the volumetric batches of incoherent material deposited thereon from said pockets as the dispensing cylinder rotates, said volumetric batches during passing said entraining rollers being accomodated in said complementary recesses.
Claim 2
Dependent Claim 209 words
Device for dispensing volumetric batches of incoherent material comprising a horizontally arranged material dispensing cylinder which is rotatable about its horizontal axis and is provided with a plurality of radially outwardly open pockets, a hopper for the material positioned at the top of the dispensing cylinder and adapted to feed by gravity incoherent material into the pockets as the cylinder rotates, a roller idly supported adjacent and downstream of said hopper and adapted to deviate a strip of packaging material around the dispensing cylinder in the direction of rotation of the latter so as to partially wrap said cylinder, and means for driving the strip of packaging material including a pair of counterrotating entraining rollers through which the strip passes and provided with complementary recesses, wherein according to the improvement said entraining rollers have their rotation axes lying in a vertical plane and their contact line lying in a horizontal plane tangential to the lower point of the dispensing cylinder so that the strip defines a horizontal run extending from the dispensing cylinder to said entraining rollers for receiving the volumetric batches of incoherent material deposited thereon from said pockets as the dispensing cylinder rotates, said volumetric batches during passing said entraining rollers being accomodated in said complementary recesses.
Claim 3
Dependent Claim 34 words
Device as claimed in claim 1 wherein means are provided for guiding a cover strip of packaginG material through said entraining rollers to cover the volumetric batches of material deposited on said horizontal run.
