Definitions

  • the invention relates to a device for separating essentially sheet-shaped products moving in a shingled stream, with a belt conveyor transporting the shingled stream, at the end of which is connected another belt conveyor running in the same conveying direction, the conveying surface of which lies below the conveying surface of the first belt conveyor , and a counting sensor scanning the products to be separated, which is arranged in the area of the step formed by the two belt conveyors, with the lower belt conveyor being associated with a driver device which can be moved in its conveying direction and which consists of a waiting position in the area of the step formed by the two belt conveyors can be set in motion by means of the counting sensor as a function of a predetermined number of products to be separated, in the sense of a advance of the driver device with respect to the lower belt conveyor and with the. Trailing edge of the last counted product can be engaged.
  • the present invention now aims to avoid this disadvantage and to further develop a device of the type specified in the introduction in such a way that a correct opening of the shingled stream in the area of the step between the two belt conveyors is guaranteed in each case.
  • the device according to the invention is characterized in that the deflecting roller of the upper belt conveyor is associated with a pressing device for the products running over the deflecting roller, which is guided by two deflecting rollers, engaging on the products, endless, preferably elastically deformable perpendicular to its direction of travel Has pressure belt, and that the front deflection roller of the pressure belt with a horizontal distance in front of the deflection roller of the belt conveyor, is substantially at the same height as this deflection roller and is adjustable and / or resiliently biased against the area of the step formed by the two belt conveyors.
  • a belt conveyor 1 which is connected, for example, to a folder (not shown) of a web-fed rotary printing press or a rotary cutting machine, folded products 2 are moved forward in the form of scales in the conveying direction (arrow F).
  • a deflection roller 4 of a belt conveyor 5 arranged downstream of the belt conveyor 1 in its longitudinal direction and on which the products 2 leaving the first belt conveyor 1 are retained is arranged below a deflection roller 3 thereof of the scale formation.
  • the lower belt conveyor 5 has mutually transverse spacing parallel to the upper belt conveyor 1 and driven at the same speed as this conveyor belts.
  • a counting sensor 6 is arranged between the forward runs of the belt conveyors 1, 5, which counts mechanically, electronically or with the aid of a laser beam and emits the predetermined pulse.
  • the counter can also be on the top
  • the lower belt conveyor 5 is assigned a driver device with a drive, not shown, which, in the example shown, is formed by an endless driver member 7 which extends parallel to the lower belt conveyor 5 and whose forward run is below the forward run of the lower one Belt conveyor 5 lies.
  • the endless driver link 7 is or the like along its length with a plurality of driver forks 8. provided the 5; protrude at a mutual transverse distance from the endless driver link, the driver link 7 being arranged such that the driver forks 8 or the like run between the parallel conveyor belts of the lower belt conveyor 5.
  • the driver element 7 is controlled by the counting sensor 6 and a control device (not shown) assigned to it so that one driver is at a standstill or in the waiting position in the area of the step formed by the belt conveyors.
  • the drive of the entraining member 7 receives a forward pulse which causes the entraining member 7 to advance at a higher speed than the lower belt conveyor 5 for a predetermined period of time.
  • the driver forks 8 or the like which come into engagement with the last counted product, push the products of the shingled stream 2 'together on the lower belt conveyor into a stack in the conveying direction.
  • the deflection roller 3 of the upper belt conveyor 1 is assigned a pressing device 9, which has an elastic endless belt 12 that engages the products and is guided over two deflection rollers 10, 11.
  • the front deflection roller 10 of this belt lies at a horizontal distance in front of the deflection roller 3 of the belt conveyor 1, to the extent that the lower run of the pressure belt 12 touches the belt conveyor deflection roller 3 essentially tangentially when no products are being conveyed.
  • the lower run Under the action of the shingled stream, the lower run is elastically deformed and, together with the front deflecting roller 10, exerts a reaction force on the upper edges of the products 2, or a significant kink in the shingled stream in front of the deflecting roller 3 of the upper belt conveyor, which causes the spring to spring open Scale flow in the area of the stage.
  • a perfect separation process is achieved even in the case of very thin or highly electrostatically charged products which tend to stick together in the area of the counter.
  • the front deflection roller 10 of this belt can be adjustable and / or resiliently pretensioned against the region of the step formed by the two belt conveyors.

Abstract

Dispositif pour séparer des produits imbriqués et essentiellement en forme de feuille, défilant dans un flux sur un transporteur à bande (1), à l'extrémité duquel est raccordé un autre transporteur à bande (5) défilant dans le même sens et dont la surface de transport est située au-dessous de celle du premier transporteur. Un palpeur de comptage (6) disposé dans la région du gradin formé par les deux transporteurs palpe les produits à séparer, et un taquet poussoir (7, 8) adjoint au transporteur inférieur et déplaçable dans le sens de transport de ce dernier peut être mis en contact avec le bord arrière du dernier produit compté, après comptage d'un nombre prédéfini de produits à séparer; au tambour de renvoi (3) du transporteur supérieur (1) est adjointe une installation transporteuse exerçant une contre-pression (9) sur les produits (2) défilant sur ledit tambour, laquelle installation comporte une bande (12) sans fin à contre-pression, élastiquement déformable, guidée sur deux tambours de renvoi (10, 11) et s'appliquant sur les produits. Le tambour de renvoi avant (10) de ladite bande est situé à une distance horizontale en amont du tambour de renvoi (3) du transporteur (1), sensiblement à la même hauteur que ledit tambour (3), et est précontraint de manière réglable et/ou élastique contre la région du gradin formé par les deux transporteurs (1, 5).
