Definitions

  • a bridge having a central cavity with open end portions includes an elongated lateral opening in the side portion of the bridge for providing lateral access to the central cavity.
  • the bridge is longitudinally movable on the surface of a worktable which supports a punching knife with webs of material or blanks positioned thereon.
  • a plurality of detachably connected cells are transversely positioned within the central cavity.
  • Each of the cells includes a pressure roller and a counter-roller positioned in spaced underlying parallel relationship relative to the pressure roller.
  • a servomotor provided in the bridge is connected to each of the pressure rollers over a chain drive and is operable upon actuation to move the pressure rollers vertically in the central cavity to a preselected height above the counter-rollers.
  • a ring member surrounding the upper portion of the bridge and rotatably supported thereon is positioned in underlying abutting relation with the surface of the pressure rollers.
  • the ring member serves to protect the pressure rollers from the cutting edges of the punching knife as the web of material positioned thereon is introduced through the lateral opening into the space between the pressure and counter-rollers for compression by the pressure rollers to thereby form an impression upon the web of material.
  • This invention relates to a blankpunching apparatus and more particularly to a blank punching apparatus that includes a bridge having a lateral opening provided in the side portion thereof to permit introduction of the blank positioned on the punching knife therethrough and into compressive relationship with a pressure roller rotatably mounted within a central cavity of thebridge.
  • Conventional devices for punching blanks or webs of material with a punching knife include a pressure roller that is supported in a frame mounted to a worktable and brought into compressive relationship with the blanks supported on the punching knife. A desired pattern is impressed on the surface of the blanks corresponding to the .cutting pattern of the punching knife.
  • the frame portion is provided with a longitudinal chamber open at the front and rear portions of the frame to permit passage of the blankson the punching knife through the chamber.
  • the frame may remain stationary relative to the worktable with the blanks and punching knife moved horizontally over the surface of the worktable through the frame.
  • the blanks and punching knife may remain fixed relative to the worktable with the frame moved horizontally over the surface of the worktable to bring the pressure rollers into compressive relationship with the blanks.
  • a blank punching apparatus that includes a plurality of pressure rollers horizontally positioned in a bridge that is movable on a worktable.
  • the pressure rollers are rotatably mounted to a horizontal arm of a lever that is arranged for swivelable movement on an axle. Movement of the lever in a desired direction will raise and lower the pressure rollers to a preselected height above the surface of an abutment member which supports the punching knife and blanks to be punched.
  • the laterally positioned pressure rollers may be used to precompress or prepunch the blanks with the center pressure roller serving as the main punch.
  • the axis of rotation of the pressure rollers may be vertically aligned by the lever so that the rollers simultaneously compress the blanks on the punching knife.
  • the blanks may be of unlimited length; however, the width of the blanks is limited to the width of the openings provided in the end portions of the frame. Increasing the width of the frame to accommodate blanks of greater surface area has been found to be economically undesirable. Furthermore. the increase in the overall size of the punching device necessitated by an increase in the width of the frame makes it more difficult for the operator to maneuver the blanks and punching knife relative to the frame and pressure rollers.
  • This invention relates to an apparatus for punching blanks or webs of material with a punching knife that includes a worktable for supporting the blanks on the punching knife in which a bridge member is positioned for longitudinal reciprocal movement on the worktable.
  • the bridge has a central cavity and an elongated lateral opening in the side portion of the bridge for providing access to the central cavity.
  • a pressure roller is rotatably mounted in the central cavity and is arranged transversely relative to the worktable.
  • An adjusting mechanism is provided for vertically positioning the pressure roller in the central cavity relative to the lateral opening so that the blanks are introduced on the punching knife through the lateral opening into compressive relationship with the pressure roller.
  • a plurality of detachably connected cells are arranged within the central cavity of the bridge.
  • Each cell includes a rotatable pressure roller and a counter-roller positioned in spaced overlying parallel relation with the pressure roller.
  • a servo-motor is provided in the bridge having a chain drive operably connected to the pressure roller for vertically adjusting the pressure roller within the central cavity to a preselected height above the counter-roller.

  • a ring member surrounds the frame of the bridge having one portion of the ring arranged in underlying relationship with the surface of the pressure roller.
  • Guide members positioned laterally of the pressure roller adjacent the lateral opening to the central cavity maintains the ring member in compressive relationship with the blank on the punching knife.
  • the ring member rotates about its axis or about an axis parallel to its axis and together with the guide plates serves to precompress the blank on the punching knife to thereby guide the blank through the lateral opening into the central cavity for further compression by the pressure rollers.
  • the principal object of this invention is to provide a blank punching apparatus that includes a bridge having a central cavity and a lateral opening in which a blank of unlimited surface area-positioned on a punching knife may be introduced through the lateral opening into the central cavity for compression by pressure rollers.
  • Another object of this invention is to provide a plurality of pressure rollers, rotatably mounted within the bridge of the punching apparatus, which may be adjustably positioned to a preselected height above the counter-rollers. cooperatively arranged with the pressure rollers. to permit punching of a single blank having a desired thickness, punching simultaneously a plurality of blanks or laminating together a plurality of blanks to form a single blank having a desired thickness.

  • the transmission rods 12 are threadedly engaged within the threaded bores 5a of the upper body portion 5.
  • the bridge I may be provided with a plurality of individual cells 13 detachably connected to each other by suitable connecting means. such as bolts.
  • Each cell includes a pressure roller 2 spaced in overlying parallel relationship with a counterroller 3 having the gap 9 provided therebetween.
  • Each combination of pressure and counter-rollers within the cells 13 may be provided with motors l0 and chain drives 11 connected to transmission rods 12 for raising and lowering the pressure rollers 2 independently of each other to a preselected height above the counter rollers 3.
  • a single motor and a common chain drive 11 may be provided for all of the cells 13 to thereby maintain the pressure rollers 2 at a desired height above the counter-rollers 3.
  • varying degrees of compression may be applied by the pressure rollers 2 upon the blanks introduced through the lateral opening 7a into the gap 9 as determined by the vertical positioning of the pressure rollers 2 relative to the counter-rollers 3.
  • the counter-rollers 3 are rigidly mounted in the bridge 1 and an equivalent structure may be provided by eliminating the counter-rollers 3 and providing a worktable having its top surface maintained at the elevation of the counter-rollers 3.
  • either the pressure rollers 2 or the counter-rollers 3 are driven so that the bridge 1 is moved horizontally on the worktable as the blank passes into frictional engagement with the respective driven roller.
  • the bridge moves across the worktable.
  • the frictional engagement between the pressure rollers 2 and the blank is broken and movement of the bridge on the worktable interrupted.
  • the bridge may be moved in the opposite direction on the worktable by feeding the blank between the pressure rollers 2 and the counter-rollers 3 in the opposite direction bringing the bridge 1 to its initial starting position on the worktable.
  • pressure rollers 2 and counter-rollers 3 placed in spaced overlying parallel relationship within the bridge 1 may be used for laminating, coating, glueing and other similar operations of blanks or webs of material by the compressive relationship of the material between the pressure rollers 2 and the counter-rollers 3 and eliminating use of the punching knife.
  • the pressure rollers 2, accordingly. may be profiled to reproduce a desired pattern upon the blank corresponding to the profile design of the roller.
  • the rollers 2 may be heated to an elevated temperature for improving the impression formed on the plastic material.
  • FIG. 3 there is diagrammatically illustrated another embodiment of the present invention in which the bridge 1 is supported for longitudinal movement upon the horizontal surface of a worktable 14 having a knife punch support base 15 for maintaining the punching knife 16 rigidly thereon.
  • a blank or any other material suitable for punching is positioned on the surface of the cutting edges of the knife.
  • the blank 17 and the punching knife 16 may be of any suitable length depending upon the capacity of'the worktable 14.
  • the pressure rollers 2 are adjustably positioned at varied elevations above the counter-rollers 3 which have top surfaces maintained in the same plane.
  • the middle pressure roller is set lower relative to the counterrollers than the two lateral pressure rollers.
  • the bridge 1 is then capable of being moved upon the surface of the worktable 14 in the direction indicated by the arrows 18 and 19.
  • the drive for the bridge 1 may be effected either by a motor operably associated with the bridge 1 supported on the frame 26, or by a motor operably associated with the middle pressure roller 2 or all the pressure rollers.

  • the rods 21 are retracted to permit placement of the ring member 24 over the bridge. Then once the ring 24 has been positioned in abutting contact with the pressure rollers 2 and the guide plates 25, the rods 21 are extended outwardly from the frame 20 until the ring 24 is loosely supported by the shafts 22.
  • the adjustable rods 21 are fixedly secured to extend outwardly from the bridge frame 20 so that the ring 24 remains rotatable on the shafts 22 but is restrained from moving axially thereon.
  • the ring 24 abutting the driven pressure rollers 2 is urged into frictional engagement with the blank 17.
  • the ring 24 is rotated as the bridge 1 moves in the direction 18 or 19 on the surface-of the worktable 14.
