Definitions

  • the invention relates to a knife holder for longitudinal cutting stations on paper processing machines with a guide rod that can be displaced in the vertical direction in a rotationally secured manner and carries a knife head with a circular knife for setting the circular knife against a counter knife.
  • a knife holder of the type mentioned is known for example from DE-PS 28 21 957.
  • the disclosed guide rod allows precise guidance and also a sensitive adjustment of the knife holder or the circular knife mounted thereon relative to the counter knife.
  • there is always a certain amount of play in all knife holder guide parts that, over time, increases due to wear and can inevitably lead to vibrations and changes in the angle of attack of the circular knife to the counter knife, particularly under load.
  • the invention has for its object to make a knife holder guide of the type described functionally reliable.
  • a clamping device which non-positively locks the guide rod in its extended setting position.
  • the circular knife which can be adjusted in the vertical direction, is expediently formed by an upper knife which can be lowered from above and the counter knife by a rotating driven lower knife, a useful addition being that the upper knife is additionally equipped with actuating means for lateral adjustment to the lower knife.
  • the anti-rotation means of Guide rod include an actuator for adjusting the angle of attack of the circular knife to the counter knife.
  • the simplest way to achieve this is to provide the clamping sleeve with an axially parallel, continuous longitudinal slot.
  • the force for constriction or for applying the clamping sleeve to the circumference of the guide rod is most easily realized according to one embodiment in that the clamping sleeve, which can be displaced longitudinally axially relative to the guide rod, has an end-face outer cone that is operatively connected to a stationary end-side inner cone of a guide bush that supports the guide rod stands. In this way, when the clamping sleeve is axially displaced, its outer cone is pressed into the inner cone of the guide bushing, its inner diameter narrowing.
  • the guide bush is provided below its inner cone with slide bearings receiving the guide rod, so that there is a sufficient distance between the inner wall of the guide bush and the outer circumference of the guide rod .
  • the clamping sleeve In order to allow the clamping force of the clamping sleeve to take effect at the right time, ie after taking the predetermined position of the circular knife relative to the counter knife, the clamping sleeve is longitudinally axially opposed to the force of a coordinated compression spring system by a diaphragm piston which is acted on by pressure medium and is displaceable on the guide rod on the Guide rod slidably arranged.
  • a particularly expedient constructive embodiment consists in that the compression spring system has a first compression spring, which is supported on the one hand on the diaphragm piston and on the other hand on an end ring surface of the guide rod, and a second compression spring is supported on the one hand on the clamping sleeve and on the other hand on a stationary housing flange of the knife holder, the spring force of which is designed to be weaker than the spring force of the first compression spring, the guide rod also being provided with a stop cone which is operatively connected to an adjustable, fixed cone seat which is at a defined distance from the inner cone of the guide bushing. In this way, the clamping force is effective in its extended state immediately after reaching the predetermined end position of the guide rod.
  • the first compression spring is expediently designed as a plate spring and the second compression spring as a spiral spring.
  • the advantage achieved by the invention is that after the precise setting of the knife age or after reaching the precisely specified setting position of the circular knife relative to the counter knife, the guide rod is completely fixed in this setting position, so that any residual play in the guide parts is eliminated, i.e. H. a rigid connection on all sides is established with the stationary knife holder housing. This guarantees a functionally reliable method of operation or compliance with a certain angle of attack in the long term.
  • the figure shows a knife holder according to the invention in Longitudinal section with a guide rod fixed in its extended position.
  • the knife holder assigned to a longitudinal cutting station has a carrier housing 1, flanged to the frame of a paper processing machine (not shown further), for a guide rod 2, to which a knife head 3 is attached with a circular knife 4, which forms an upper knife to a counter knife 6 designed as a lower knife, which in is fixed in a known manner on a driven shaft 7.
  • the cutter head 3 is assembled in a known manner from the segments 8a, 8b and 8c for the purpose of laterally adjusting the circular knife 4 to the counter knife 6, a bushing 9 and 11, in which an axis 12 is guided, being fastened in the segments 8a and 8c .
  • bushings 13 and 14 are fastened, with the aid of which two membranes 16 and 17 are clamped on the axis 12.
  • the membranes 16 and 17 are clamped on the other side between the segments 8a and 8b or 8b and 8c.
  • the membrane 17 divides the interior of the cutter head 3 into two chambers 18 and 19 and serves as a pressurized second piston for the axis 12.
  • the membranes 16 and 17 thus form actuating means for the lateral displacement of the circular knife 4.
  • the free cross section of the membrane 16 is smaller than that of the membrane 17 because the segment 8b has an annular shoulder 21 in the chamber 19.
  • the membrane 16 is used exclusively for sealing the chamber 19 against the bushing 9.
  • a sealing of the chamber 18 against the bushing 11 is not necessary because a bore receiving the bushing 11 is designed as a blind hole 22 in the segment 8c and the axis 12 in pressure equalization Has connection, not shown, in the form of holes from the blind hole 22 to the chamber 18. With 23 and 24 pressure medium connection holes are designated.
  • a knife holder 28 is on ball bearings 26 and 27 freely rotatably mounted on which the circular knife 4 is attached.
  • the carrier housing 1 of the knife holder is designed as a cylinder 29 for a drive for the vertical adjustment of the circular knife 4 to the counter knife 6 in the form of a membrane piston, consisting of an axial on an end pin 31 of the guide rod 2 between a stop disc 32 and a ring shoulder 33 of the guide rod 2 displaceably mounted piston head 34 and on the one hand resting on the piston head 34 and on the other hand by means of an air connection 36 having a cover 37 clamped to the cylinder 29 membrane 38.
  • the guide rod 2 itself is mounted by means of two slide bearings 39 and 41 in a guide bush 42 which is in the cylinder 29 is screwed in and secured by means of a lock nut 43.
  • a conical seat 46 is installed below the guide bush 42 by means of a support ring 44 and is operatively connected to a stop cone 47 of the guide rod 2.
  • a prestressed compression spring designed as a plate spring 48 is supported between the piston head 34 and an end ring surface of the guide rod 2.
  • a clamping sleeve 51 provided with a longitudinal slot 49 surrounds the guide rod 2 and is supported with its upper end face on the piston head 34. The supporting force is applied by a spiral spring 52 which is slightly preloaded in the upper end position of the piston head 34 and which is supported on the one hand on a flanged-on base part 53 of the cylinder 29 and on the other hand on a support disk 54 surrounding the clamping sleeve 51.
  • the compression spring system is matched to one another in such a way that the spring force of the plate spring 48 is higher than the spring force of the spiral spring 52.
  • the clamping sleeve 51 On its lower end face, the clamping sleeve 51 is provided with an outer cone 56, which is operatively connected to a stationary end inner cone 57 of the guide bush 42.
  • the inner cone 57 of the guide bush 42 and the cone seat 46 on lower support ring 44 have a defined distance.
  • the conical seat 46 defines the defined vertical lowering position of the circular knife 4 relative to the counter knife 6, while a stop ring surface 58 forms the retracted end position of the guide rod in cooperation with the underside of the support ring 44.
  • the height of the cone seat 46 can be adjusted relative to the counter knife 6.
  • a short, tab-like rail 59 is inserted into the guide rod 2, which in a known manner according to the German patent specification 28 21 957 between two stationary guide parts in the form of rollers 61 acting on opposite sides from both sides of the rail 59 and spring-loaded on one side is led.
  • the other roller which is mounted in a bearing block 62 which is displaceable perpendicular to the plane of the drawing, can be adjusted by means of an adjusting screw 63 against the spring force acting on the opposite side.
