Patent ID: 8530764

Claim:
A device for continuously weighing articles in arrival from a conveyor organ, the device comprising: a weighing apparatus ( 40 ) arranged downstream of the conveyor organ ( 80 ), which weighing apparatus ( 40 ) detects a weight of articles transiting continuously thereon, a first conveyor ( 20 ) for abutting and engaging a side of an article (X) in arrival from the conveyor organ ( 80 ), which first conveyor ( 20 ) transfers the article (X), once the article (X) has been engaged, and draws the article (X) along an advancement direction (WW) towards the weighing apparatus ( 40 ), the first conveyor ( 20 ) being activatable such as to convey the article (X), once engaged, towards the weighing apparatus ( 40 ) along the advancement direction (WW) at a first advancement velocity (V 1 ); a second conveyor ( 30 ) associated to the weighing apparatus ( 40 ) and arranged to receive the article (X) while the article (X) is engaged to and drawn by the first conveyor ( 20 ) and the article (X) is in advancement along the advancement direction (WW) towards the weighing apparatus ( 40 ), the second conveyor ( 30 ) being activatable to convey the article (X) at a second advancement velocity (V 2 ) which is greater than the first advancement velocity (V 1 ) at which the article (X) is advanced by the first conveyor ( 20 ), to disengage the article (X) from the action of the first conveyor ( 20 ) and to advance the article (X) freely onto the weighing apparatus ( 40 ) in order to detect a relative weight thereof and convey the article (X) downstream of the weighing apparatus ( 40 ); wherein the second conveyor ( 30 ) comprises a closed-ring conveyor belt ( 300 ) which is activatable to receive the articles (X) from the first conveyor ( 20 ) and to convey the articles (X) along the weighing apparatus ( 40 ); and, wherein the first conveyor ( 20 ) comprises at least one closed-ring conveyor belt ( 200 ) and at least one drawing element ( 70 ) borne by the conveyor belt ( 200 ) for engaging an article (X), the conveyor belt ( 200 ) having a transport direction which is parallel to a transport direction of the conveyor belt ( 300 ) of the second conveyor ( 30 ) and a development which is such that an article (X) to be weighed, received on a fixed inlet plane ( 50 ), can be abutted and engaged at a side thereof by the drawing element ( 70 ), the development further being such that the article (X), once weighed and received by a fixed outlet plane ( 60 ), can newly be abutted at a side thereof by the drawing element ( 70 ) for subsequent transfer downstream of the fixed outlet plane ( 60 ).
