Definitions

  • the present invention relates to a cycle conveyor according to the preamble of claim 1.
  • Tactile conveyors are usually used for the rapid transport of rectangular flat objects, such as printed and folded sheets of paper, especially newspapers. They are used in particular for the isochronous transfer of the printed sheets from the folder or a storage station and their delivery to a collating or inserting machine. It bridges the mostly large distance between the print shop and the mail room and must therefore be suitable for the construction of curves or loops or for a rotation around its longitudinal axis.
  • a clock conveyor of this type is known from PCT publication WO 86/03476.
  • the U-shaped profile of the rail of this cycle conveyor makes it difficult to bend the rail for curves and / or to twist it about the longitudinal axis. Deformation of the rail while maintaining the profile is complex.
  • the object of the present invention is to eliminate this disadvantage.
  • the solution is achieved by the characterizing features of claim 1.
  • the cheeks are continuously subjected to a closing force by a spring.
  • the grippers are opened against them Closing force and the cheeks are to be kept in their open position by a locking device which counteracts the closing force.
  • the object of the present invention is to simplify a gripper of the type mentioned without sacrificing its advantages.
  • the cycle conveyor has an articulated chain 1, which consists of alternately arranged links 2, 3 of the first and second type, which are connected to one another by a universal joint 4.
  • One gripper 5 is mounted on each of the links 2 of the first type, whereas the links 3 of the second type determine the distance between the following grippers 5.
  • the links 2, 3 have in common that two axes 6 and 7 are fastened thereon, on each of which two guide rollers 8, 9 and 10, 11 are free are rotatably mounted.
  • Spacer sleeves 12, 13 and 14, 15 hold the guide rollers at a certain mutual distance.
  • the guide rollers 8 to 11 roll on the narrow sides of the parallel legs 16 of a guide rail 17 which is H-shaped in cross section.
  • axle 7 is diametrically penetrated by an axle stub 18 on which a guide roller 19 is rotatably mounted.
  • Their diameter is at least approximately the same but smaller than the distance between the legs 16, so that the guide roller can alternately roll on one of the two legs 16.
  • the universal joints 4 connecting the links 2, 3 have a universal joint 20 which is rotatably connected to the adjacent link about the longitudinal axis of the chain.
  • the universal joint 20 is formed by an axis cross 21, of which one beam is pivotally mounted in the joint member 2 or 3.
  • a bracket 22 is pivotally articulated on the other bar, the web of which is freely rotatably mounted on a pivot pin 23.
  • the links 2 and 3 can thus be rotated relative to one another about the longitudinal central axis of the articulated chain 1 and also about the bars of the axis cross 21 and thus simultaneously about all three spatial axes.
  • the links 2 of the first type also have an upward-facing extension 24, to which an angle bracket 25 is attached.
  • Its trailing flank 26 forms the fixed cheek of the gripper 5, against which a movable cheek 27 acts.
  • This is through the one arm of the three-armed lever with the other arms 28 and 29 formed, which is pivotally mounted on the axis 7.
  • a pin 30 laterally points away from the arm 28, on which a spring 31 that is biased under pressure is supported at one end.
  • the other end of the spring is mounted on the triangular leg of the angle bracket 25.
  • the three-armed lever can be swiveled between two end positions. In one the cheek 27 lies against the flank 26 and in the other the arm 18 lies at the lower end of the angle bracket 25.
  • the connecting straight line 32 intersect between the axis 7 and the pin 30 and the central axis of the spring 31 an angle ⁇ .
  • the angle lever 27, 28, 29 passes through a dead center position and then swings into the other end position.
  • the connecting straight line 32 and the central axis 33 of the spring 31 are aligned axially and the spring 31 is most compressed.
  • a cam roller 34 is freely rotatably mounted on the free end of the third arm 29 of the three-armed lever. This interacts with fixed guide curves at a transfer or delivery station, which move the three-armed lever from one end position to the dead center to the other in order to hold a printed product immovably or to deliver it to a further processing machine.
