  • US 4,132,403 discloses a sheet transfer device for a printing press. It are by a transfer drum that is at least two angularly apart has spaced grippers, sheets from one stack to one in one Printing machine located continuously rotating recording drum moves.
  • the Transfer drum with the grippers is at a relatively low speed rotated, and each of the grippers can be on the transfer drum and relative to the other Grippers can be moved angularly.
  • each gripper is accelerated after the latter has recorded a sheet at the receiving station, so that the arrival of the Gripper at a transfer station, where it transfers the sheet to the take-up drum passes, the sheet moves at the same speed as the take-up drum becomes.
  • each gripper is braked evenly, so that when it goes to Has come back, the gripper is moving at the same speed how the bow moved there
  • US 4,290,595 shows a rotatable feed or pre-gripper drum.
  • a continuously rotatable feed device for sheet-fed rotary printing presses has one Pre-gripper drum and a gripper bridge movable relative to the drum.
  • the device further includes a crank-driven linkage transmission mechanism is attached to the drum and rotates with it and operationally with the Gripper bridge is connected to move it.
  • US 4,629,175 discloses a method and an apparatus for the display of arcuate products that are fed in a stream of flakes.
  • the one Folder coming sheet-shaped products are initially over a certain Route transported before they are caused to overlap each other.
  • To the Braking products so that the overlap can take place and the products become one completely normal supply flow can be arranged without being damaged the products are gripped by grippers that run exactly along a support arcuate path are moved, with the products being gripped by the grippers Speed of a delivery belt is braked and deposited there.
  • US 4,767,112 discloses a product transfer and transport device for folded copies.
  • a chain wheel chain engages between the folded sheets of a folded product provided on which grippers are attached, the gripper arms at their outer end exhibit.
  • the gripper elements are at a transfer position or station on a arched path, the fold copies between a counter surface and a movable tongue of the gripper elements, which is then under the pressure of a spring close, be pushed.
  • the gripper elements can be controlled by cornering open and close to take the product copy.
  • the product copies can be transported in a scale formation to a receiving or delivery station will.
  • the tapes of the tape system must move at a higher speed than that Move the cutting cylinder surfaces. This results in a relative movement between the Band surfaces and the surface of the signature until the signature by one transverse cut between the cutting cylinders is separated from the web.
  • the signatures are therefore subject to considerable mechanical stress, which can lead to damage and lubrication points on the signatures.
  • the present invention is based on the object Speed difference between the surfaces of the cutting cylinder and the Exclude belt system associated with cutting cylinders.
  • Another object of the present invention is reliable and safe Grasp the signatures emerging from a tape system.
  • a Conveyor device for flat printed products a transport device for transport of the signatures as well as a lot of poor, each one of the Transport device assigned gripping device for gripping the from the Have transport devices appearing signatures, the gripping devices the arms during their rotational movement in non-raised parts of a transport element Immerse the transport device to close the leading edge of a respective signature seize.
  • the embodiments of the present invention offer the considerable advantage that enough space is now available for a gripping device, with one of their To move components past the front edge of the signatures.
  • the non-sublime Parts of the circumferential transport elements then make it possible to deflect the Trailing edge of the previous signature without the signatures hindering each other.
  • the circumferential transport elements of the transport device is a segmented tape with raised and non-raised surface parts.
  • the arms with their gripping device to immerse them in the non-raised parts of the segmented bands steer the trailing edges of the preceding ones Signatures and take the leading edge of the next signature.
  • a Distance between the signatures to be transported is no longer necessary because now there is enough space to place the gripping devices in the non-raised parts of the to immerse segmented tapes and the leading edge of a signature in one more reliable way to take. Because there is no more space between the signatures is necessary, the speed difference between the Cutting cylinder surfaces and the belt system can be eliminated.
  • FIG. 1A shows the general arrangement of an embodiment of the invention.
  • a running web of material 1 enters a gap between a pair of cutting cylinders.
  • the pair of cutting cylinders comprises an anvil cylinder 3 with on its circumference arranged cutting rails 4 and a cutting cylinder 2.
  • the move out of the gap between the Cylinder surfaces 9 emerging signatures in a transport device 10 the co-operating encircling elements, which in Fig. 1A as a flat or flat belt 11 and a segmented belt 12, each around rollers 16 run, are shown.
  • the segmented band, or the segmented bands 12 have raised or thick Parts 13 and non-raised or thin parts 14 or gaps, the raised parts 13 preferably have a regular distance 15 from each other.
  • the raised parts 13 mainly support first and second signatures 5, 6, as shown in FIG Figures 2 and 3 is shown in detail. In one embodiment of the invention the length of the signatures 5 and 6 exceeds the length of the raised parts 13.
  • the drive of the rollers 16 and the drive of the pair of cutting cylinders 2 and 3 are of this type coupled that the speed of the Schpeid cylinder surfaces 9 and Surface speed of the raised parts 13 of the segmented belts 12 in are essentially the same. This creates a speed difference between the Cutting cylinders 2, 3 and the transport device 10 avoided. Consequently, they are out the gap emerging, cut in the transverse direction signatures 5, 6 in the Transport device 10 transported side by side.
  • the transport device 10 shown in FIG. 1A is a braking device 17 assigned, which has a plurality of arms 18 rotating about an axis of rotation 26.
  • the arms 18 are above bearings shown in FIG. 1B Pin 31 rotatably mounted.
  • the arms 18 are mounted on a turntable, which in the Figures is not shown.
  • the turntable on which the arms 18 are mounted is on a level below the in Fig. 1B shown arms 18 and over a star-shaped control disc, which in Fig. 1B as disc-shaped element 19 is shown.
  • the turntable rotates about an axis 26. As can be seen from the circumference of one through the pins 31 of each of those shown in Fig.
  • the turntable has a smaller Diameter than the disc-shaped element 19 and is opposite to that disc-shaped element 19 offset in such a way that the turntable is about Axis 26 rotates while disc-shaped member 19 rotates about axis 26A.
  • the turntable and the disc-shaped element 19 at the same speed.
  • each Arm 18 is connected directly to the turntable via the pins 31, such as as described in U.S. Patent No. 5,452,886, the arms 18 are not directly associated with connected to the disc-shaped element 19. Rather, there is an end to each Arm 18 belonging control rod 19A with a respective pivot point 34 of the disc-shaped element 19 connected to a desired one Create a speed profile for rotating the arms 18 about the axis 26. The the second end of each control rod 19A is connected to the respective arm 18 via a pin 33 connected. The control rods 19A determine the positions of the arms 18 at each point of the speed profile created in the configuration of FIG.
  • the Arms 18 of the braking device 17 rotate about the axis of rotation 26 in a through the Arrow 27 indicated direction of rotation.
  • each arm 18 includes on its distal end a gripping device 23 in the form of a gripping element which, for. B. from a movably attached gripper finger 24 and a fixedly attached - Gripper rail 25 exists.
  • Control levers 20A are mounted on each of the arms 18 Connection with cams or control cams 30 and cam followers or sensing elements 32 are actuated to cause the gripper fingers 24 to open and close, while the arms 18 are rotated about the axis 26 by the turntable.
  • the gripping devices 23 move in the Area of the non-raised parts 14 into it, which is a more reliable grip of the Allows leading edges of the signatures when they exit the sheet guide 28.
  • slow down arms 18 gradually move along their rotational path along axis of rotation 26. Consequently comes from the rotational movement of the arms 18 a scaled formation of the signatures state in which each of the gripping devices 23 has taken a single signature.
  • the rotational movement of the arms 18 about the axis of rotation 26 is thus with a irregular speed profile of the arms 18 executed.
  • FIGS 2 and 3 show an example of the signature transfer from Transport device to the gripping device 23 in detail.
  • Fig. 2 shows the rotating movement of the arm 18 in synchronism with the non-raised surface part 14 of the segmented band 12 shown.
  • the gripping device 23 comprises a movable mounted gripper fingers 24 and a fixedly mounted gripper rail 25.
  • Fig. 2 shows the Gripper fingers 24 at a point in time before this trailing edge 8 of a preceding one Signature 8 deflects.
  • the signatures 5, 6 to be transported do not Have a distance (i.e. gap) between them.
  • the leading edge 7 of the following signature 6 to be transported is, as shown, near the rear edge 8 of the Signature 5.
  • the second signature 6 is mainly supported by the raised part 13, whereas the trailing edge 8 of the first signature 5 over the non-raised part 14 is arranged so that the respective rear edge 8 can be bent or deflected.
  • Fig. 3 shows the gripper finger 24 after this by its rotary and radial Movement has deflected the rear edge 8 of the first signature 5.
  • the Signature trailing edge 8 moves into the area of the non-raised part 14 of the segmented belt 12, the gripper finger 24 behind the front edge 7 of the second signature 6 can move.
