Abstract

Abstract Conveyor apparatus for transporting an imbricated formation of objects, such as a succession of folded newspapers, comprises a conveyor track adjoining the trailing edges of the newspapers, and pairs of grippers moving along the conveyor track and gripping the trailing edges of the newspapers. A distribution or device is disposed ahead of the conveyor track to provide the intervals between successive newspapers of the imbricated formation so that the distance between successive trailing edges of the newspapers corresponds to a predetermined value.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 90 words
Conveyer apparatus for flat objects supplied in an imbricated formation, said apparatus comprising a conveyer track on which the objects are transported with successive trailing edges of the objects resting on the track, a plurality of grippers travelling along an endless path, at least a portion of which directly adjoins the conveyer track, and means for moving the grippers, in a region of said portion of the endless path thereof, in the conveying direction of the conveyer track, to cause said grippers to grip said trailing edges of the objects.
Claim 2
Dependent Claim 90 words
Conveyer apparatus for flat objects supplied in an imbricated formation, said apparatus comprising a conveyer track on which the objects are transported with successive trailing edges of the objects resting on the track, a plurality of grippers travelling along an endless path, at least a portion of which directly adjoins the conveyer track, and means for moving the grippers, in a region of said portion of the endless path thereof, in the conveying direction of the conveyer track, to cause said grippers to grip said trailing edges of the objects.
Claim 3
Dependent Claim 24 words
Conveyer apparatus according to claim 1 comprising an endless travelling conveyer member, said grippers being secured to said conveyer member at regularly spaced intervals.
Claim 4
Dependent Claim 71 words
Conveyer apparatus according to claim 1 comprising a distribution means arranged ahead of said conveyer track and comprising a plurality of driving members each cooperating with a respective one of said objects in said imbricated formation, said driving members being successively arranged at uniformly spaced intervals and being moved in a direction parallel to said conveyer track at a travelling speed greater than the conveying speed of the supplied imbricated formation.
Claim 5
Dependent Claim 36 words
Conveyer apparatus according to claim 3, in which said distribution means comprises an endless travelling member having one length running parallel to said conveyer track, said driving members being secured to the latter said travelling member.
Claim 6
Dependent Claim 55 words
Conveyer apparatus according to claim 4, in which said driving members each comprises a two-armed lever pivotally connected to said endless travelling member, said lever having one free end urged to protrude into the path of conveyance of the imbricated formation and a stop member positioned to pivot the levers out of the conveying path.
Claim 7
Dependent Claim 32 words
Conveyer apparatus according to claim 2, in which said grippers are arranged in pairs, the two grippers of a pair being disposed symmetrically at both sides of said endless travelling conveyer member.
Claim 8
Dependent Claim 31 words
Conveyer apparatus according to claim 1, comprising an endless travelling chain guided at least over a portion of its length along said conveyer track, said grippers being secured to said chain.
Claim 9
Dependent Claim 33 words
Conveyer apparatus according to claim 1, in which said grippers each comprises a movable jaw adapted to travel at a greater speed than the conveying speed of said track upon gripping said objects.
Claim 10
Dependent Claim 42 words
Conveyer apparatus according to claim 8, in which said grippers each comprises a fixed jaw, said means causing each movable jaw to effect a pivoting movement towards a respective fixed jaw for exerting clamping action on the trailing edges of said objects.
Claim 11
Dependent Claim 39 words
Conveyer apparatus according to claim 9, in which said movable jaw is supported for undergoing a helical motion, said means comprising a spring operated retracting mechanism having a relieved position in which it holds the grippers in clamping position.
Claim 12
Dependent Claim 34 words
Conveyer apparatus according to claim 10, in which said means comprises a link motion mechanism to pivotally move the movable jaws of the grippers into open position against the action of the retracting mechanism.
Claim 13
Independent Claim 90 words
A method for conveying flat objects supplied in an imbricated formation onto a conveyer track with successive trailing edges of the objects resting on the track, a number of grippers travelling along an endless path being adapted to grip said trailing edges during a portion of their travelling path, said method comprising arranging said imbricated formation, prior to transfer thereof to the conveyer track and the grippers, so that the interval between successive objects of the formation corresponds to a predetermined value or to a whole multiple of this value.
Claim 14
Independent Claim 90 words
A method for conveying flat objects supplied in an imbricated formation onto a conveyer track with successive trailing edges of the objects resting on the track, a number of grippers travelling along an endless path being adapted to grip said trailing edges during a portion of their travelling path, said method comprising arranging said imbricated formation, prior to transfer thereof to the conveyer track and the grippers, so that the interval between successive objects of the formation corresponds to a predetermined value or to a whole multiple of this value.
