Definitions

  • the invention relates to a device for separating products moving in a shingled stream.
  • Printing machines such as rotary rotary printing machines, are usually followed by folding devices in which the printed products are folded crosswise and lengthwise.
  • the products are then transferred to a boom conveyor in the form of a scale, for example with the aid of a delivery wheel.
  • a boom conveyor in the form of a scale
  • a delivery wheel In order to be able to transport the products away, they must be combined into stacks with a predetermined number of pieces.
  • various types of devices are already in use, which also make it possible to determine the number of pieces of each stack and to change them if necessary.
  • a counting device periodically identifies a specific example of the products that are transported in the form of scales on the delivery conveyor belt.
  • the counting is carried out by scanning the upper product edge and the separation of the products after reaching a predetermined number of products by pinching or stopping the stream of shingles behind the last counted product at a point following the counting point, so that the last product is still assigned to the stack or the backflow does not disturb the counter sensor when the current is stopped.
  • the distance between the counting point and the separation point results in inevitable inaccuracies because the scale flow in the known devices is not completely regular.
  • the known procedure is also relatively complicated in terms of control technology and involves the risk of being accidentally caught of the last product in question or a drawing of the immediately following product.
  • a device in which a counting head with a sensor is arranged in the conveying direction at a distance in front of a step between two conveyor belts transporting the scale flow.
  • the sensor is actuated by the respective leading edges of the printed products and generates counting pulses.
  • a relatively complex mechanism intervenes in the stream of shingles in order to detach individual products from it and to convey them upwards. With this device, however, the printed products cannot be combined and removed in a simple manner from the product stream in the area of the second conveyor.
  • the invention aims to provide a device for counting and separating products moving in a shingled stream, which, with a simple design and control technology, enables precise separation of the products to be summarized from the product stream, etc. without impairing the subsequent products or the subsequent product stream.
  • the invention relates to a device for separating products moving in a shingled stream, with a belt conveyor transporting the shingled stream, at the end of which a further belt conveyor is connected in the 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;
  • This device is characterized according to the invention in that the counting sensor is arranged in the region of the step formed by the two belt conveyors and the rear section of each from the upper to the lower Belt conveyor falling product senses that the lower belt conveyor is associated with a known in the conveying direction movable driver device and that this driver device from a waiting position in the area formed by the two belt conveyors by means of the counting sensor depending on a predetermined number of products to be separated in the sense a lead of the driver device in relation to the lower belt conveyor can be set in motion and can be brought into engagement with the rear edge of the last counted product.
  • the main advantage of the invention is that the counting of the products and the separation of the product flow takes place at one and the same point on the conveyor.
  • the entraining device has at least one entraining fork or the like mounted on an endless entraining member that rotates parallel to the lower belt conveyor. that protrudes above the conveying surface of the lower belt conveyor.
  • a cantilever belt conveyor 1 which a folder, not shown, e.g. a web-fed rotary printing press, downstream, folded products are moved forward in a scale-like manner.
  • Products 2 can e.g. slide out of the blades of a delivery wheel onto the belt conveyor 1.
  • a deflection roller 4 of a belt conveyor 5 arranged downstream of the belt conveyor 1 in its longitudinal direction, on which the products 2 leaving the first belt conveyor 1 fall while maintaining the scale arrangement, is arranged below a deflection roller 3 thereof.
  • the lower belt conveyor 5 has three mutually parallel 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 levels of the forward runs of the belt conveyors 1, 5, which e.g. can be a mechanical sensor.
  • an air nozzle can optionally be provided in the area of the deflection rollers 3, 4, which is located between the rear sections of the falling products blows.
  • 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 is below the forward run strums of the lower belt conveyor 5.
  • the endless driver member 7 is or the like along its length with a plurality of driver forks 8 extending transversely to the lower belt conveyor 5. provided that protrude from the endless driver link at a mutual transverse distance, the driver link, as shown in FIG. 2, being arranged such that the driver forks 8 or the like. run between the three parallel conveyor belts of the lower belt conveyor 5.
  • the driver member 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 region of the step formed by the belt conveyors and the drive of the driver member 7 each time a predetermined one is reached
  • Product number receives a lead pulse, which causes the driver 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 each of which at the beginning of a driver cycle in the area of the counter sensor 6 with the the last counted product come into engagement, the products in the direction of conveyance form a stack.
  • the proper engagement of the driving forks 8 or the like. is secured by opening the shingled stream during the falling of the products over the stage formed by the belt conveyors 1, 5.
  • the endless driver link can be provided with a single driver.
  • the forward speed of the driver member must then be controlled so that the driver after pushing the products together has moved back to the waiting position in the area of the counting sensor before the counting sensor has counted the specified number of products. If there are several drivers over the length of the driver member, a corresponding control is carried out, that is, the forward speed and the length of the driver member are matched to the feed speed of the belt conveyors 1, 5 so that one driver is in the waiting position before the counting process is completed.
  • a reciprocating driver device could also be provided.
