Abstract

Abstract A device for placing at regular distances delicate objects coming from a production line onto a receiving line. The objects are firstly pushed from the production line into a channel and then accelerated therein by a jet of air until they are engaged by pulling elements projecting from the bottom of the channel and arranged on an endless chain moving at the same speed of said receiving line. At the end of the channel the objects pass into receptales defined by the adjacent portion of a pair of parallel belts, from which they are expelled onto the receiving line by means of ejectors mounted on an endless belt located above said pair of belts.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 267 words
A device for placing at regular distances delicate or fragile objects coming from a production line onto a continuously moving receiving line characterized in that it comprises an intercepting mechanism (13) cross-wise to such production line (4) for stopping the objects in arrival (2), a channel (10-11) extending between the production line (4) and the receiving line (21), means of transfer (12) Operating in coordination with such intercepting mechanism for the transfer of the objects (2) of the production line (4) into the channel (10-11), at least one nozzle (17) placed at the entrance of channel (10-11) and cyclically connected to a source of compressed air, so as to emit a jet of air suitable for pushing forward and accelerating each object (2) along channel (10-11), pulling elements (18) spaced on chains (19) in endless-belt fashion and travelling at the same speed as and in synchronized manner with the receiving belt (21) below the channel (10,11), said pulling devices containing a portion which projects within the channel for pulling objects (2) already in acceleration along such channel, a pair of belts (24) extending from the exit of the channel to above the receiving line (21) and having two opposed and parallel sections which are equipped peripherally with projections forming receptacles or seating (25) open below for receiving and holding objects (2) coming from the channel, said belts (24) being driven at the same speed as that of the receiving line (21), an endless belt (28) equipped with ejectors that push the objects outside the seatings (25) into the respective receptacles (20) of the lower-lying receiving line (21).
Claim 2
Independent Claim 267 words
A device for placing at regular distances delicate or fragile objects coming from a production line onto a continuously moving receiving line characterized in that it comprises an intercepting mechanism (13) cross-wise to such production line (4) for stopping the objects in arrival (2), a channel (10-11) extending between the production line (4) and the receiving line (21), means of transfer (12) Operating in coordination with such intercepting mechanism for the transfer of the objects (2) of the production line (4) into the channel (10-11), at least one nozzle (17) placed at the entrance of channel (10-11) and cyclically connected to a source of compressed air, so as to emit a jet of air suitable for pushing forward and accelerating each object (2) along channel (10-11), pulling elements (18) spaced on chains (19) in endless-belt fashion and travelling at the same speed as and in synchronized manner with the receiving belt (21) below the channel (10,11), said pulling devices containing a portion which projects within the channel for pulling objects (2) already in acceleration along such channel, a pair of belts (24) extending from the exit of the channel to above the receiving line (21) and having two opposed and parallel sections which are equipped peripherally with projections forming receptacles or seating (25) open below for receiving and holding objects (2) coming from the channel, said belts (24) being driven at the same speed as that of the receiving line (21), an endless belt (28) equipped with ejectors that push the objects outside the seatings (25) into the respective receptacles (20) of the lower-lying receiving line (21).
Claim 3
Dependent Claim 57 words
A device, as claimed in claim 1, wherein said belt (28) lies in a vertical plane passing between the contiguous sections of said pair of belts (24) and that the lower section of said belt (28), beginning from the exit of said channel (10,11), descends toward the receiving line (21) and intersects said pair of belts (24).
Claim 4
Dependent Claim 104 words
A device, as claimed in claim 1, wherein the production line is composed of a pair of parallel production belts (4) between which said channel (10,11) extends along the median line, and that said transfer device comprises a propulsion mechanism equipped with a pair of receptacles (12) and actuated with alternating movement cross-wise in respect to belts (4) so that, while one of said receptacles is aligned with a production belt (4), the other is aligned with channel (10,11) and vice versa, said propulsion mechanism being provided with wings (13) which intercept objects (2) arriving on the production belt not aligned with receptacles (12).
