Abstract
The device includes at least one continuous flexible suction conveyor which is equipped with openings and which conveys articles along a transfer path from an article feeder to an article received. A discharge point for the trimmings is provided along the transfer path. A suction system is also provided which is associated with the conveyor and which generates a suction through the openings along the transfer path. At least one obturator element, which is movable along the transfer path and which temporarily closes the openings of the conveyor opposite the trimming or trimmings, is provided.
Claims18
A device for eliminating at least one trimming from a series of articles fed to said device comprising:
- at least one continuous flexible suction conveyor which is equipped with openings and which conveys said articles along a transfer path from a feeder to a receiver, a discharge point for the at least one trimming being provided along the transfer path;
- a suction system which is associated with said conveyor and which generates a suction through said openings along said transfer path;
- and
- at least one obturator element which is movable along said transfer path and which temporarily closes said openings of the conveyor opposite said at least one trimming, the at least one obturator element operating independently of the conveyor including as to speed;
- wherein said at least one obturator element is mounted on a continuous flexible member which extends parallel to said conveyor at least along a portion of said transfer path;
- and
- wherein said continuous flexible member comprises two parallel continuous flexible elements, between which said at least one obturator element is applied, said continuous flexible elements being arranged on sides of the conveyor at least along said transfer path.
A device for eliminating at least one trimming from a series of articles fed to said device comprising:
- at least one continuous flexible suction conveyor which is equipped with openings and which conveys said articles along a transfer path from a feeder to a receiver, a discharge point for the at least one trimming being provided along the transfer path;
- a suction system which is associated with said conveyor and which generates a suction through said openings along said transfer path;
- and
- at least one obturator element which is movable along said transfer path and which temporarily closes said openings of the conveyor opposite said at least one trimming, the at least one obturator element operating independently of the conveyor including as to speed;
- wherein said at least one obturator element temporarily closes said openings of the conveyor opposite a front trimming and/or an end trimming of a series of articles;
- wherein said at least one obturator element is mounted on a continuous flexible member which extends parallel to said conveyor at least along a portion of said transfer path;
- and
- wherein said continuous flexible member comprises two parallel continuous flexible elements, between which said at least one obturator element is applied, said continuous flexible elements being arranged on sides of the conveyor at least along said transfer path.
A device for eliminating at least one trimming from a series of articles fed to said device, comprising:
- at least one continuous flexible suction conveyor which is equipped with openings and which conveys said articles along a transfer path from a feeder to a receiver, a discharge point for the at least one trimming being provided along the transfer path;
- a suction system which is associated with said conveyor and which generates a suction through said openings along said transfer path;
- and
- at least two obturator elements which are movable along said transfer path and which temporarily close said openings of the conveyor opposite said at least one trimming, the at least two obturator elements operating independently of the conveyor and being controlled independently of each other.
A method for eliminating at least one trimming from a series of articles fed to a device comprising engaging articles by means of suction by a continuous flexible suction conveyor, transporting the articles along a transfer path, inserting into said transfer path at least one obturator element which is separated from said conveyor and which enters between said conveyor and the at least one trimming, and moving said at least one obturator element together with the conveyor along the transfer path in order to intercept the suction opposite the at least one trimming causing elimination of the at least one trimming from said transfer path as a result of falling.
A device for eliminating at least one trimming from a series of articles fed to said device, comprising:
- at least one continuous flexible suction conveyor which is equipped with openings and which conveys said articles along a transfer path from a feeder to a receiver, a discharge point for the at least one trimming being provided along the transfer path;
- a suction system which is associated with said conveyor and which generates a suction through said openings along said transfer path;
- and
- at least one obturator element which is movable along said transfer path and which temporarily closes said openings of the conveyor opposite said at least one trimming, the at least one obturator operating independently of the conveyor, whereby the conveyor is controlled to move the at least one obturator in synchronism with the at least one trimming being discharged and reposition said at least one obturator into a position for a subsequent discharge of another of the at least one trimming.
