Definitions

  • the present invention relates to an envelope feeder for printing presses, in which the envelopes are fed continuously from a refill envelope stack to a storage stack in the form of a forced clutch, a transport arrangement having a first conveyor belt, which together with a second conveyor belt, is arranged around a stack between the refill stack and the storage stack Deflection pulley is guided around in order to turn over the enveloped transported envelopes onto the second conveyor belt, which transports the envelopes under the storage stack, with an adjustable scraper above the first conveyor belt holding back the refill stack.
  • the US-A-4,369,959 already describes an envelope feeder for printing presses, in which the envelopes are fed in the form of a forced clutch from a refill envelope stack to a storage stack, with a transport arrangement with a first conveyor belt, which together with a second one, is located between the refill stack and the storage stack Conveyor belt is guided around a deflection roller in order to transfer the enveloped transported envelopes to the second conveyor belt, with a scraper over the holds the refill stack on the first conveyor belt.
  • the object of the present invention is therefore to create an envelope feeder of the aforementioned type, in which the envelopes are reliably transported with a very small overlap distance, the overlap distance having only small scatter values.
  • the second conveyor belt transports the envelopes under the storage stack and in that the first conveyor belt has an air-permeable perforation, under which conveyor belt in the area of the refill stack there is a vacuum chamber which generates a suction flow onto the bottom envelope of the refill stack to produce a temporary one Driving connection between the conveyor belt and the bottom envelope for transporting it under the scraper is arranged, the scraper to change the overlap of the Envelopes are adjustable in the transport direction relative to the vacuum chamber and height-adjustable relative to the air-permeable conveyor belt, and the overlap corresponds to the distance between the rear edge of the vacuum chamber in the transport direction and the rear edge of the lowermost envelope in the refill stack located behind this edge of the vacuum chamber.
  • an air squeezing element is arranged above the second conveyor belt in front of the storage stack, in which case the air squeezing element is a rotatable hold-down roller.
  • a device for example a light barrier for monitoring the height of the storage stack, and a device for controlling the speed of the air-permeable conveyor belt depending on the height of the storage stack be provided and further a device, for example a light barrier for monitoring the height of the refill stack and emitting a signal when this height drops below a predetermined value.
  • Fig. 1d it is shown how the envelopes come to rest nicely on one another, if, as in Fig. 1c), only one small scaling distance was chosen.
  • Fig. 2 it is clearly shown how the scaling distance 5 can be set very easily, because it also corresponds to the distance between the left edge of the vacuum chamber and the left edge of the envelope 1. This scaling distance can now be deliberately and specifically varied by moving the envelope beige to the left or right.
  • this can be accomplished very easily with the displaceable barrier and the simultaneous stripper 6, because this barrier or stripper 6 can be displaced to the left and right and can then be fixed in any position.
  • the wiper 6 can also be shifted in height and can be fixed again in any position.
  • the task of the envelope feeder is now to form a storage stack 8 (FIG. 3), of which the scale feeder of the printing press can print the envelopes at any time can take away.
  • This storage stack 8 is achieved in that, in the case of a stack, further envelopes are continuously pushed in at the bottom and the stack thus becomes ever larger if the envelopes are not continuously removed again from the scale feeder of the printing press. So that this storage stack cannot get too big, it is provided with a light barrier so that the envelope feed can be electronically controlled in this way.
  • a photocell can also be installed in the refill stack 11, which emits a signal as soon as you have to refill.
  • a hold-down roller 7 directly in front of the storage stack 8, which ensures that any air that may be present is pressed out of the envelopes.
