Definitions

  • the invention relates to a cutting machine for three-sided trimming of stacks from book blocks, brochures or the like.
  • a cutting station with side knives and with a cross knife, with a pressing device for exerting a pressing pressure on the stack of material to be cut lying on the system table and with a feed device for the cycles Conveying the stack of material to be cut into the trimming station.
  • 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.
  • 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 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.
  • 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 trimming station is automatically supplied with the stacks of cut material 1 made from book blocks, brochures or the like from an insertion slide 7, which can be moved forwards and backwards in the longitudinal table 6 in a longitudinal recess 6a, bearing against lateral alignment rails 8, 9 which are adjustable in size.
  • the head and foot side are first trimmed by the two side knives 2 and then the front of the stack of the trimmings is trimmed by the cross knife 3.
  • a pre-pressing device 10 is located in the entry of the three-knife cutting machine at right angles to the infeed direction of the stacks of cut material 1, to which the individual stacks of cut material 1 are guided in a lying manner. 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 are arranged on both sides of the plane of movement of the stack of cut material 1 and have chains 19, 18 running around deflection sprockets 15, 15 and 17, 18, respectively. 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 press plates 13 of the chains 19, 20 was provided in such a way that the surface of the press plates 13 is located slightly outside the pitch circle of the sprockets 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 with a driven transport roller 36 and an upper transport roller 37 which can be swung in and out via a working cylinder.
  • the stack of cut material 1 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 which 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 transport rollers 46 from the stack of cut material 1 and, at the same time, the stack of cut material 1 is aligned on the aligning rail 8 via an aligning rod 51 which is oriented in a vertical plane and can be pivoted into the movement path 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 immediately in front of the three-knife cutting machine, which enables the pressed stack of cut material to be introduced almost directly 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.
  • fixed press plates with a lower one are arranged within a conveyor system 53, 54 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 moved 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 pivoted 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 range 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.
