Definitions

  • the invention relates to a device for separating substantially 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 is below the conveying surface of the first belt conveyor, and one Products to be separated scanning sensing sensor, which is arranged in the area of the stage formed by the two belt conveyors, the lower belt conveyor being assigned a moving device which can be moved in the conveying direction thereof and which, from a waiting position in the region of the stage formed by the two belt conveyors, by means of the counting sensor as a function of a predetermined number of products to be separated can be set in motion in the sense of a advance of the driver device with respect to the lower belt conveyor and can be brought into engagement with the rear edge of the last counted product.
  • the present invention now aims to avoid this disadvantage and to further develop a device of the type specified in the introduction so that in any case a correct opening of the shingled stream in the area of the step between the two belt conveyors is ensured.
  • the device according to the invention is characterized in that the deflecting roller of the upper belt conveyor is assigned a pressing device for the products running over the deflecting roller, which has an endless pressing strip, which is guided over the deflecting roller and engages the products, preferably elastically deformable perpendicular to its direction of travel, 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).
  • 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 counting sensor can also be arranged on the top of the scale flow, as shown in dashed lines at 6 '.
  • the lower belt conveyor 5 is assigned a driver device with a drive, not shown, which, in the example shown, is formed by a continuous endless driving member 7 which extends parallel to the lower belt conveyor 5 and whose forward run lies below the forward run of the lower belt conveyor 5 .
  • the endless entraining member 7 is provided over its length with a plurality of entraining forks 8 or the like, which protrude at a mutual transverse distance from the endless entraining member, the entraining member 7 being arranged such that the entraining forks 8 or the like. Between the parallel conveyor belts of the lower belt conveyor 5 run.
  • the entraining element 7 is controlled by the counting sensor 6 and a control device (not shown) associated therewith in such a way that one entrainer is at a standstill or in the waiting position in the region of the step formed by the belt conveyors.
  • the drive of the driving element 7 receives a advance pulse, which causes the driving element 7 to advance at a higher speed than the lower belt conveyor 5 for a predetermined period of time.
  • the deflecting roller 3 of the upper belt conveyor 1 is assigned a pressing device 9 which has an elastic endless belt 12 which engages the products and is guided over two deflecting 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 kinking of the shingled stream in front of the deflecting roller 3 of the upper belt conveyor, which causes the spring to crack 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 to one another 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.
