  • the transport carriage 21 released from the buffer section 18 can, in the same way as described above, receive a movement impulse in the direction of the delivery point via the elastically deformable impeller 24.
  • the printed products 23 are delivered in a lower part of the orbit at the discharge station 9. Following the discharge station 9 follows in the direction of rotation U considered the already mentioned climb path 26, along which the empty trolley 21 are promoted for the purpose of returning to the transfer station 5 in a higher-lying portion of the orbit U.
  • the buffering of trolley 21 with printed products 23 serves to ensure a continuous supply of the further processing device 51 with printed products 23 operated with another working cycle.
  • the level of the buffer section 18 with trolley 21 is monitored by the controller 4.
  • a first buffer sensor 61 is arranged in front of the buffer section 18 and a second buffer sensor 62 is arranged after the buffer section 18.
  • the first buffer sensor 61 is used to count the transport carriage 21 entering the buffer section 18, and the second buffer sensor 62 is used to count the transport carriage 21 leaving the buffer section.
  • the level of the sensor data from the buffer sensors 61, 62 can now be continuously increased. determine the number of currently located in the buffer section 18 Dolly 21.
  • the feeding device 1 is operated to control the level of the buffer section 18 at a variable clock rate.
  • the number of transport carriages 21 in the buffer section 18 can be increased or the number of transport carriages can be increased by lowering the take-over cycle rate of the feed device at a constant delivery clock rate, depending on the fill level of the buffer line 18 21 are reduced in the buffer section 18.
  • each gripper 22 of a trolley 21 contains a printed product 23
  • each gripper 22 of a trolley 21 contains a printed product 23
  • only trolleys 21 each having a printed product 23 are fed to the buffer section 18. Faulty products are therefore removed in the transfer section and empty cycles without printing product 23 are omitted.
  • the delivery conveyor 3 comprises for this purpose a discharge device 8 with a chute 19 for discharging defective printed products 23, which are not taken over by a gripper 22 of a trolley 21, from the transfer section 12 by means of gravity support.
  • the delivery conveyor 3 further includes a sensor device 31 for detecting tact-correct products.
  • the sensor device 31 is in FIG. 1 viewed in the conveying direction F, for example, arranged in front of the conveying gap of the double belt conveyor 30.
  • the control device 4 switches the retaining element 10 into the release position for the relevant transfer cycle. Consequently, a transport carriage 21 is released into the transfer section for the respective transfer cycle.
  • control device 4 does not switch the retaining element 10 into the release position for the respective acquisition cycle. As a result, no transport carriage 21 is conveyed to the transfer section 12 for the corresponding transfer cycle.
  • the faulty product is a faulty printed product 23, this is indeed conveyed into the takeover section 12, but is not taken over by a transporting carriage 21, since such was not released.
  • the unaccounted, defective printed product 23 is rather deflected at the positioning device 17 down and falls onto the chute 19 of the discharge device 8, via which the defective printed product 23 slips into a collecting container.
  • the positioning device 17 in this case also has the function of a deflector.
  • the sensor device 31 for detecting clock-correct printed products 23 it is ensured that in each case a clock-correct printed product 23 is always transferred to the transport carriage 21 and released into the buffer section 18 in the respective transfer cycles. Since in the buffer section 18, as already mentioned above, a buffer of trolley 21 is formed with printed products 23, the transfer melts but not the fill level can not affect the working cycle of the subsequent further processing device 51.
