Definitions

  • the invention relates to a three-knife cutting machine, with a front knife and two side knives by a drive device are driven to be out of phase on a cut, a front cut and at least one Carry out a side cut.
  • Three knife cutting machines for three sided trimming of Printed products such as books, brochures and the like have been known for a long time.
  • the material to be cut becomes Cutting is conveyed to and on a cutting table aligned with the knives and from a press plate or the like held on the cutting table. With the two Side knives become the head and foot side at the same time of the material to be cut. Before or after in a further step the cut with the front knife the front.
  • the trimmed material is cut automatically moved out of the cutting area and for example by means of a conveyor belt removed from the three-cutting machine. at These three-knife cutting machines are thus cut in a single cutting station. Since the material to be cut is only once it has to be aligned, there are significant advantages compared to three-knife cutting machines with two stations. So that the front and side knives do not collide Front cut and side cut out of phase.
  • a three-knife cutting machine is for example disclosed in DE 32 01 836 A.
  • This one Drive device for the knives each of which is a so-called Guide gear and a so-called functional gear connected upstream having.
  • the functional gear is through a Gear transmission with one during one revolution one A touring wave changing gear ratio formed.
  • Another three-knife cutting machine is in CH 537 260 A reveals. This is where the knives are driven a driven single-speed shaft mounted in the machine body.
  • a crank is arranged at the ends of the single-turn shaft, a connecting rod engages each of the crank pins.
  • a universal joint pull rod is also used to drive the front knife provided that should make it possible to use the usual double-sided knife pull through a single-sided knife pull to replace.
  • the invention has for its object to provide a three-knife cutting machine of the type mentioned, which has a simpler structure with fewer parts and which is still reliable. According to the invention the object is achieved by the features of claim 1.
  • the two levers are driven by a single drive curve enables a simple construction with few parts as well as one low deformation movement.
  • the Drive curve endlessly formed. This curve at least moves two swiveling levers with which the front knife and at least a side knife to be driven.
  • the drive of the Messer therefore takes place over just one curve.
  • This curve can cause the uneven movement of the knives be determined.
  • the drive with the common drive curve results in a phase-shifted movement of the knife carrier.
  • There the drive device with few and robust individual parts is producible, there is also a very low deformation Movement of the knife or knife holder.
  • the drive curve is driven, for example, via a pinion and simultaneously moves at least two levers with which the front knife and at least one side knife are driven.
  • a second drive curve can be provided, which is connected to the first drive curve via a torsionally rigid shaft.
  • the lever for the front knife is preferably a linkage that engages a knife belt.
  • the two side knives are preferably fixed at a distance from one another on a carrier shaft which is drive-connected to at least one of the levers mentioned for carrying out the cutting movements.
  • the three-knife cutting machine 1 has a front knife 4 and two side knives 5, 6 on by a drive device 2 out of phase and driven non-uniformly.
  • a front cut is made before the side cut.
  • the Cutting order is due to a change in the direction of rotation the shaft 24 is reversible in a simple manner.
  • the two side knives 5 and 6 are each with a carrier 31 arranged on a carrier shaft 11. The distance of this two knives 5 and 6 to each other by moving the two carriers 31 to adapt to the format of the to be cut Cuttings 30 can be adjusted.
  • the two knives 5 and 6 are arranged parallel to each other and each have a cutting edge 5a, 6a. With two at a distance from each other arranged pivotable struts 29, the carrier shaft 11 on a machine frame 3 only indicated in FIG. 1 attached that the cutting knives 5 and 6 to execute the Cutting movements are essentially vertically movable.
  • the Cuttings 30, for example a stack of printed products is in the direction of arrow 36 ( Figure 2) here Cutting table not shown fed.
  • the circumcised Sliced material is cut in the same direction by the three-knife slicer 1 led away.
  • the front knife 4 has a cutting edge 4a on.
  • the knife 4 shown in Figures 1 and 2 is on one attached with a coupling 8 connected knife carrier 7.
  • On Linkage 9 is articulated with an upper end 9a with the coupling 8 connected.
  • the coupling 8 is on the machine frame 3 led.
  • the linkage 9 is essentially according to FIG. 1 according to the double arrow 37 arranged vertically movable. This is the linkage 9 at its lower end via a joint 13 with a lever 16 connected to a cam roller 18 in a drive curve 23 engages a cam disc 22.
  • the lever 16 is as can be seen a two-armed angle lever, which between the Joint 13 and the cam roller 18 with a bearing 34 rotatably on Machine frame 3 is stored.
  • the arm 16a of the lever 16 on which the cam roller 18 is arranged is much shorter than the arm 16b on which the linkage 9 is articulated.
  • the cam disc 22 is preferably driven by a motor 28, via a pinion 27 with spur toothing 26 the cam 22 is engaged.
  • the cam disc 22 is driven counterclockwise according to arrow 25.
  • a second lever is simultaneously activated by the drive curve 23 19 moves, the one-armed and at one end around an axis 20 is pivotable on a bearing 35 fixed to the frame is supported.
  • a swivel 14 arranged, which the lever 19 with a rod 10th connects that at an upper end 10a rotatably with the carrier shaft 11 is connected.
  • a cam roller 21 is arranged on the lever 19, which engages in the drive curve 23.
  • the drive curve 23 can be designed as a closed curve or as an open curve.
  • the drive curve 23 is preferably a closed curve, with which comparatively large cutting forces are absorbed can. Basically, there is also an open curve Spring or complementary curve conceivable.
  • the rod 10 leads driven cam 22 movements according to the double arrow 39 out. Accordingly, the struts 29 are fixed to the frame Axis 40 swiveled.
  • the drive curve 23 is circumferential and designed so that the linkage 9 and the rod 10 are moved out of phase.
  • the Swiveling movements of the levers 16 and 19 take place in each case when the cam roller 18 or 21 in a recessed area 23a. If the cam 22 in the direction of Arrow 25 rotated, the lever 16 and then the lever 19 is pivoted. Accordingly, first with the front knife 4 and then with the side knives 5 and 6 cut.
  • the clippings 30 must be led away from the machine 1 and at the same time, another clippings to be trimmed fed to the cutting table and fixed on it.
  • the material to be cut 30 thus aligned, cut and transported away.
  • the front knife 4 and the two side knives 5 and 6 are in one position in which transport is possible.
  • the knives 4, 5 and 6 can be replaced by a corresponding one Design of the drive curve 23 accelerated or that the cycle time remaining for the transport is delayed is optimal.
