Definitions

  • the invention relates to a method and an apparatus for three-sided trimming of stacks from book blocks, brochures or the like, in which side knives trim the top and bottom and a cross knife the front of the stack of material to be cut and the material to be cut is pressed against a support table during trimming .
  • the material to be cut such as stacks of book blocks, brochures or other printed products
  • a feed device aligned and held on the cutting table by a press ram.
  • the head and foot are trimmed in a first work cycle and the front cut in a second work cycle, whereupon the material to be cut is automatically ejected by an extension arm and guided out of the three-knife cutting machine by a conveyor belt.
  • Air pockets in the material to be cut reduce the compressive stress under the ram, see above that the material to be cut is more compressed in the area of the knife for the side trimming due to its linear contact than under the press ram.
  • This relatively strong compressive stress under the knife leads to the elongation of the paper up to tearing before the start of the cut and to pulling forward individual paper sheets or paper layers under the press ram, which results in hollow cut surfaces.
  • the object of the invention is to provide a three-knife cutting machine of the generic type with which the cutting quality and the effective performance can be improved.
  • the method according to the invention is characterized in that a stack of material to be cut is subjected to a pre-pressing, in that the air enclosed in the stack of material to be cut is pressed out beginning on one side of the stack under increasing pressure.
  • the stack of material to be cut can be detected and subjected to a pre-pressing during the passage, in that the enclosed air is pressed out against the direction of flow beginning on the inlet side.
  • the pressing force advantageously acts on the stack of material to be cut from both sides.
  • the air pockets present in the material to be cut can thereby be largely eliminated, so that a material stack which is highly compressed before the press ram is put in place is available for the cutting process, which significantly improves the cutting quality and permits a higher cycle sequence.
  • the effective performance of the three-knife cutting machine is increased by increasing the number of products per cutting insert.
  • a pre-pressing device which is preferably arranged directly in front of the trimming station and has endless conveying means which exert a pressing force on the stack of cut goods and act on the stack of cut goods from above and below and which exert the same speed the stack of goods to be cut can be fed via a conveyor.
  • Another device for carrying out the method is characterized by a lower press plate arranged in the feed device, preferably directly in front of the trimming station, within a conveyor system with a continuously driven upper and lower endless conveying means, as well as an upper press plate, which are actuated between an oblique to the lower press plate Opening position can be pivoted into a closing position parallel to the lower press plate by applying a pressing pressure to the working strands of the conveying means and to which the stacks of material to be cut can be fed in cycles.
  • FIG. 1 of the drawing shows a trimming station with two side knives 2, a cross knife 3 and a press ram 4, which presses a stack of cut material 1 against a support table 5 for three-sided trimming.
  • the cutting station stacks 1 of book blocks, brochures or the like are fed automatically from an insertion slide 7, which can be moved back and forth in the inlet table 6 in a longitudinal recess 6a, bearing against lateral alignment rails 8, 9 which are adjustable in size.
  • the head and foot sides are first trimmed by the two side knives 2 and then the front of the stack of cut goods is trimmed by the transverse knife 3.
  • a Vorpreßein device 10 which the individual stack 1 are fed cyclically lying. During the passage of the stacks of cut material 1 through the pre-pressing device 10, the air enclosed in the stack 1 is pressed out progressively against the direction of passage beginning on the inlet side.
  • the pre-pressing device 10 is formed by an upper and lower plate chain 11, 12 driven at the same speed and rotating, with pressing plates 13 oriented transversely to the direction of travel, which arranged on both sides of the plane of movement of the stack of cut material 1 and having chains 19, 18, which run around deflection chain wheels 15, 16 and 17, 18, 20 are articulated.
  • the chains 19, 20 are driven by a drive sprocket 25 via chains and gearwheels, not shown in detail.
  • the working strands of the two chains 19, 20 are slidably guided in the pressing zone on support rails 26, 27.
  • the articulation of the pressure plates 13 of the chains 19, 20 was provided in such a way that the surface of the pressure plates 13 is located slightly outside the pitch circle of the chain wheels 15-18, thereby preventing the stack 1 from being cut.
  • a trouble-free entry of the material to be cut 1 into the pre-pressing device 10 and also a trouble-free removal can be achieved by a wedge-shaped tapering plate chain inlet 28 and outlet 29.
  • adjusting spindles 33 on a support frame 32 of the lower plate chain 12 on the input and output sides which engage in a nut thread piece 34 of a support frame 30 of the upper plate chain 11 and are jointly motorized via drive means, not shown in detail be operated.
  • the pressing force advantageously acts from above and below on the stack of material to be cut 1, for which purpose the working strand of the lower plate chain 12 is positioned in a higher level with respect to the entry level of a feed belt 35.
  • a stack of cut material 1 to be pressed arrives via the feed belt 35 in front of an inlet lock 39 which is controlled in the path of movement by a light barrier 40 and which releases the stack of cut material 1 in accordance with the machine speed for introduction into the pre-pressing device 10.
  • a pair of feed rollers with a lower transport roller 36 driven by the drive sprocket 25 and an upper transport roller 37 which can be swung in and out via a working cylinder.
  • the stack 1 to be cut is taken over by the plate chains 11, 12 of the pre-pressing device 10 and transported forward until its front edge reaches a light barrier 43.
  • a leading stack of cut material 1 comes against the alignment rail 8, conveyed by a lower pair of transport rollers 45 driven by the plate chain drive and an upper pair of transport rollers 46 that can be pivoted on and off via working cylinders.
  • a light barrier 48 is provided, by means of which the speed of the pre-pressing device 10 is regulated in such a way that the stack of cuttings 1 hits the alignment rail 8 at a slower speed while being aligned with a side stop 50.
  • they lift up the upper trans port rollers 46 from the cutting material stack 1 and at the same time an alignment of the cutting material stack 1 takes place on the alignment rail 8 via an alignment rod 51 which can be swiveled into a vertical plane by a working cylinder 49.
  • the pressed and precisely aligned stack of cut goods 1 is gripped behind by the insertion slide 7 and transported to the cutting station of the three-knife cutting machine.
  • the pre-pressing device 10 is arranged in a straight line arrangement directly in front of the three-knife cutting machine, which is approximately enables direct feeding of the pressed stack of cut material into the cutting station.
  • the stacks 1 of cut material are fed via an indicated infeed conveyor 52 installed at right angles to the infeed conveyor 35.
  • FIG. 4 shows the pre-pressing device 10 in a modified embodiment.
  • the revolving plate chains there are fixed press plates arranged within a conveyor system 53, 54 with a lower press plate 55 arranged in a horizontal plane and a pivotable upper press plate 56 cooperating with the lower press plate.
  • the upper press plate 56 is used for trouble-free entry and exit from the pre-press device brought out of the plane of movement of the stack of material to be cut by means of the cylinder 59.
  • the upper press plate 56 can be swiveled downward from an open position inclined to the lower press plate 55 into a closed position parallel to the lower press plate 55 while simultaneously exerting a pressing pressure on the working strands of the conveyor system 53, 54 and thus on one in the effective area of the pressing plates 55, 56, the stack of sliced goods 1 transported in cycles.
  • the two press plates 55, 56 preferably have a covering 57, 58 made of an elastic material, which is useful for gentle treatment of sensitive products.
  • the distance between the conveying means 53, 54 and the pressing plates 55, 56 from one another can be changed by means of adjusting means.
  • the pressing plates 13 are replaced by a number of belts 64 oriented in the running direction at a defined distance from one another.
  • the distance between the belts 64 can serve to accommodate the back areas, for example when prepressing book blocks with a bulky back.
  • FIG. 5 shows a last embodiment variant of a pre-pressing device with a fixed lower press plate 62 as a support surface and a fixed swiveling upper press plate 63 which is brought into operative connection with the lower press plate 62.
  • a working cylinder 60 ' is provided, which brings the upper press plate 63 from an open position inclined to the lower press plate 62 into a closed position parallel to the lower press plate 62 and at the same time press pressure on a stack of cut material transported by conveyors 61 of a rotating chain system onto the lower press plate 62 1 exercises.
  • the second working cylinder 59 ′ engaging on the upper press plate 63 brings about an additional stroke of the press plate 63 for trouble-free insertion and export of the stack of cut goods 1.
