Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the object of the invention is to provide a device according to the preamble of claim 1, which is of simple construction and which allows strong compressed air blasts to be supplied to the outlet openings within the punched edges.
  • the path between the opening in the side surface of the fork or the ring part and the outlet openings in the punching cylinder can be kept short.
  • the fork or the ring part acts as a valve slide in relation to the inlet openings in the punching cylinder. This results in strong pulses of compressed air.
  • An embodiment according to claim 2 is particularly simple in terms of production technology. In order to adapt the position of the punching cylinder to the prevailing conditions, an embodiment according to claim 3 is preferred intended.
  • the configuration according to claim 4 provides simple handling, in particular in the case of adjustable punching cylinders.
  • a configuration according to claim 6 is preferably provided.
  • an embodiment according to claim 7 is preferably provided.
  • an embodiment according to claim 8 is preferably provided.
  • the punch cylinders can be short or long axially. If they are short, their shape is more like a disk than a cylinder in common usage.
  • the device is suitable for removing any sheet material from punched material areas, such as for removing stamping remnants from web edges perforated by stamping, but also for removing labels punched out of sheet material.
  • the punching cylinders can have the shape of punching rings, be designed as a solid body, be composed of segments or also consist of a carrier cylinder with a punching sleeve attached.
  • Fig. 1 shows in perspective two disc-shaped punch cylinders with forks cooperating with them.
  • Fig. 2 shows, partly in section, a view of a punch cylinder according to Fig. 1 from its narrow side with an associated fork.
  • Fig. 3 shows a side view of a punch cylinder according to Fig. 1 with an associated fork, partially in section.
  • Fig. 4 shows a punch cylinder with attached punch segments and an associated fork.
  • Fig. 5 shows a side view of a punch cylinder.
  • Fig. 6 shows a closed punching edge, in which a compressed air outlet opening lies.
  • Fig. 7 shows a closed punched edge in which two compressed air outlet openings are located.
  • Fig. 8 shows an end of a punch cylinder with a ring cooperating with it and a drive gear in an exploded view.
  • FIG. 9 shows a section along the line IX-IX in FIG. 8 according to the composition of the parts shown in FIG. 8.
  • FIG. 10 shows a box for receiving the punched-out material areas in its interaction with a punching cylinder and an abutment cylinder.
  • Figures 1 to 3 show a stationary, driven shaft 2, on the axially displaceable and lockable two disc-shaped punch cylinders 4, 6 are non-rotatably.
  • the rotationally fixed connection is brought about in that a wedge on the shaft engages in a groove 8 of the punching cylinders 4, 6.
  • the fork 30 is provided with a guide hole 42 which runs parallel to the shaft 2 and through which a shaft 44 passes.
  • the shaft 44 is in turn mounted radially displaceable relative to the shaft 2.
  • the fork 30 can thus axially and radially to the punch cylinder 4 or 6 respectively assigned to it be moved.
  • the fork 30 is stationary during operation and the punch cylinder 4 or 6 rotates.
  • the compressed air emerging from the opening 34 of the fork 30 thus passes successively into the inlet openings 18 of the short channels 14 and, if it cannot be introduced into one of the inlet openings 18 during the transition from one channel 14 to a subsequent channel 14, is stowed. This results in very high compressed air pulses.
  • an elongated carrier cylinder 60 of punched segments 62 is provided, which has axial pins 64, 66 for storage.
  • a drive gear 68 which extends at an axial distance from an end face of the support cylinder 60 and thus leaves space for a fork 70, which is basically designed in the same way as the fork 30 according to FIGS. 1 to 3.
  • Axial bores 72 which correspond to the bores 46
  • radial bores 74 which correspond to the radial bores 48, run in the carrier cylinder.
  • These radial bores 74 coincide with bores 76 in the punching segments 62.
  • each closed punching edge 78 of the punching segments 62 encloses four outlet openings 79.
  • FIG. 5 shows a punch cylinder 80 on which only one of a plurality of closed punch edges 82 is indicated.
  • Axial bores 84 which correspond to the axial bores 46, and radial bores 86, which correspond to the radial bores 48, extend through the punching cylinder 80.
  • a gear 92 is attached, on the outside of which there is a journal 94.
  • a bearing journal 98 is also attached to the other end face 96 of the punching cylinder 80.
  • the space 100 between the end face 88 and the gear 92 serves to accommodate the fork, not shown.
  • FIG. 6 shows a circularly closed punching edge 110, in which an outlet opening 112 opens centrally.
  • FIG. 7 shows an elongated, closed punched edge 120, in the end regions of which an outlet opening 122, 124 for compressed air opens.
  • FIGS. 8 and 9 show a punch cylinder 130 with projecting closed punch edges 132, within which outlet openings 134 for compressed air open.
  • the compressed air is fed to the outlet openings 134 via channels 136 which are formed within the punch cylinder 130 and have inlet openings 138 on a lateral annular surface 140 of the punch cylinder 130.
  • the annular surface 140 encloses a cylinder shoulder 142 on the punch cylinder 130, the peripheral surface 144 of which is a bearing surface for an annular part 146.
  • an opening 150 opens out in the circumferential direction of the punching cylinder 130, from which compressed air is to be supplied in sequence to the inlet openings 138 via a channel 152 in the ring part 146.
  • An assembly-serving fork part 154 is attached in one piece to the ring part 146.
  • the channel 152 ends on the inlet side in an internally threaded section 156, which can receive an externally threaded attachment 158 on a compressed air supply part 160.
  • the gear 164 is by means of screws 166, which pass through holes 168 in the gear 164, in threaded holes 170 of the end face of the cylindrical Screw approach 142.
  • FIG. 10 shows a punch cylinder 180 which interacts with a rotatably mounted abutment cylinder 182 arranged below it.
  • Sheet-shaped material to be punched out is passed through a gap between the punching cylinder 180 and the abutment cylinder 182 and is then discharged obliquely upwards via a rotatably mounted support roller 186.
  • the box 188 is designed on the inside as a kind of labyrinth, on the inner surfaces of which the punched-out material areas are repeatedly reflected, as indicated by solid arrows.
  • Compressed air partly flows through the box in a vortex shape, as indicated by dashed arrows.
  • a discharge nozzle 196 for the punched-out material areas opens, which is connected to a suction device, not shown.
  • the entry slot 192 is delimited at the bottom by a wall 198, which is directed approximately tangentially obliquely upwards to the abutment cylinder 182 and on which a doctor blade 202 is attached which scrapes the circumferential surface 200 of the abutment cylinder 182.
  • the inlet slot 192 of the box is delimited by a wall 204 pointing away from the punching cylinder 180, which in cross section forms approximately an L with the wall 206 of the box 188 adjoining it.
