Definitions

  • the present invention relates to a device for trimming folded, in particular multi-sheet, printed products, such as e.g. Newspapers, magazines and brochures, at least on the side edge parallel to the fold edge according to the preamble of claim 1.
  • the receiving compartments are driven in rotation about a common, horizontal axis and extend in the radial direction.
  • the receiving compartments are open on the circumference and on the two end faces of the device designed as a processing drum.
  • the printed products to be trimmed are inserted into the receiving compartments with their folded edge through the openings of the receiving compartments arranged on the drum circumference and fall onto the base serving as a support.
  • Controllable clamping arrangements are present in the receiving compartments, which clamp the printed products at least during the cutting process.
  • the clamping arrangements are released when the receiving compartments extend downward around the axis of rotation during their rotational movement.
  • the temporarily released printed matter slide outwards and, with its trimmed side edge, bumps against a stop that is at a short distance from the circumference of the Processing drum runs.
  • the printed products are clamped again.
  • the printed products which now protrude somewhat beyond the opening of the receiving compartments are then moved past a stationary knife element which interacts with a knife element which is arranged at the opening of the receiving compartments and rotates with the latter.
  • the protruding edge strip is cut away by the interaction of the two knife elements.
  • the trimmed, no longer clamped printed products slide out of the receiving compartments and are transported away by a conveyor.
  • the printed products are conveyed out of the receiving compartments against a stop under the effect of gravity and centrifugal force.
  • this can damage the side edge to be trimmed and, in the case of multi-part printed products, can also cause the individual parts of the printed product lying one inside the other to slip. Since the finished trimmed printed products are also conveyed out of the receiving compartments under the effects of gravity and centrifugal force, the finished conveyor does not ensure that the finished printed products are taken over in the correct position.
  • a similar device for trimming printed products is described in EP-A-0 602 594.

  • the printed products to be trimmed are fed hanging with their folded edge at the bottom and dropped into the receiving compartments which are open at the bottom.
  • a support separate from this is provided below the processing drum, on which the printed products come to rest with their folded edge.
  • the printed products fall back under the effect of gravity into the receiving compartments of a second processing drum with a horizontal axis of rotation, in which the printed products are trimmed at the side edges running at right angles to the folded edge.
  • a cutting device of comparable type is known from CH-A-685 153, which likewise has a processing drum with radial receiving compartments which are open on the circumference and on the end faces.
  • the printed products to be trimmed are introduced with their side edge to be trimmed opposite the folding edge into the receiving compartments and dropped against a stop.
  • the printed products, which are to be trimmed at the stop at the stop assume a waiting position, from which the printed products are displaced in the radial direction against the axis of rotation into the cutting position at the appropriate time by means of a displacement device.
  • the displacement device detects the printed products on the fold edge.
  • the printed products are shifted outwards again and are removed from the receiving compartments in the upper region of the processing drum by means of a travel conveyor running above the processing drum.
  • the conveyor has grippers arranged one behind the other at regular intervals, which grasp the printed products on the folded edge.
  • the present invention has for its object to provide a device of the type mentioned in which the printed products in a gentle manner both in the trimming for the parallel to the folded edge side edge and possibly also the right-angled side edges as well as in the for Takeover can be brought to the correct positions by the conveyor.

  • the clamping device 44 is opened (see also the corresponding representations in the receiving compartments denoted by 4 'in FIGS. 5 and 9).
  • the movement of the displacement device 37 now begins from the starting position into the first operative position, in which the printed matter 50 is in a second cutting position (area F, FIG. 4).
  • the printed product 50 is clamped again by means of the clamping device 44, so that the edge 50b now to be cut is clamped between the pressure bar 56 and the associated connecting strut 10. This is shown in the receiving compartments denoted by 4 ′′ in FIGS. 5 and 9.
  • the side edge 50b is cut (so-called front or front trimming) by the interaction of the stationary knife element 51 with the knife element 52. This occurs in the area designated G in FIG. 4.
  • the clamping device 44 is then released again and the displacement device 37 is now displaced from the first operative position into the second operative position.
  • the now finished trimmed printed product is pushed into the removal position in which it protrudes from the circumferential opening O of the receiving compartment 4 and can be gripped by the grippers 48 of the conveyor 46.
  • This pushing out into the removal position is shown in FIGS. 5 and 9 in the receiving compartments denoted by 4 ′′ ′′ and takes place in the region denoted by H in FIG. 4.
  • the distance between the grippers 48 is smaller than the division of the receiving compartments 4.
  • the displacement device 37 can always be advanced for the same distance for each format to get from the starting position to the first active position and from there to the second active position. As a result, the design effort for the displacement device 37 is kept as low as possible.
  • the guided pushing out of the printed products 50 in the radial direction from a basic position into the second cutting position and then into the removal position ensures that the printed products 50 always take a precisely defined position for trimming the side edge 50b and for removal by the conveyor 46.
  • a processing drum with a vertical drum axis can also be used, in which case the cutting of the side edge 50b opposite the folding edge 50a takes place on an end face of the processing drum, as is the case with the device described in the previously mentioned EP-A-0 602 594 .
  • the trimming of the side edges 50c running at right angles to the fold edge 50a takes place in a second processing drum, which can be connected upstream or downstream of the first processing drum.
