Definitions

  • the invention relates to a device for removing stripped parts, especially waste pieces, from a blank or the like. containing sheet of material, which rests on a stripping surface so that the stripping part spans a breakthrough of the stripping surface and is pressed by this under pressure of at least one stripping member, in particular a stripping pin, the stripping member being assigned an abutment in the direction of movement of the stripping member below the stripping part.
  • stripping devices which are preferably provided in a set-up table outside the punching machine.
  • stripping station is of particular importance for production, since if it is used incorrectly, it takes the greatest part of the overall set-up time and a poorly set stripping station leads to ongoing disruptions to the production process.
  • the punched cardboard sheet is freed of waste after reaching a predetermined latching position on the stripping surface usually offered by a stripping board or a die by means of stripping pins or cutters that press upwards.
  • the first step in the development of the stripping technique was the top tool pin, which pushes the scrap through the opening of the stripping board. Then there was an additional lower tool with lower pins, which are aligned with the upper tool pins and hold the waste piece in place.
  • the break-out opening in the break-out area must be kept smaller at various points than the waste piece assigned to it, so that it rests in small areas on the break-out area or die with higher friction.
  • the resistance now arises when the stripping pin hits the waste thanks to the friction generated.
  • DYN pin a stripping pin with a tip, the iw conical side walls of which have concave contours in cross section.
  • this tip hits the piece of waste, which, by placing it on the breakthrough edges, offers so much resistance that this tip can penetrate slightly into the material of the piece of waste. This prevents undesired lateral evasion of the piece of waste.
  • the piece of waste bends; the tension between it and the breakthrough wall provides the DYN pin with enough friction to achieve the desired frictional connection with the waste piece, which if necessary makes a lower tool unnecessary when using the DYN pin.
  • the inventor has set itself the goal of further improving the stripping of waste pieces from material sheets and, above all, of simplifying the tools required for this - not least because of the storage effort for reduce the tools; since almost every sheet design requires a special tool, the cost of warehousing is disproportionately high with the previous tools.
  • the abutment is a surface which is movable and / or resilient within the opening - at least partially in an inclined position - at a distance from the break-out surface, which in its rest position is that located in the material sheet Roughly engages with the piece of waste and is designed so that it can be converted into an angle of inclination to the sheet of material by the stripping member when the waste piece is moved - that is, primarily when lowering.
  • the abutment as a resilient surface of a tongue-like spring which is fixed at one end to the stripping surface or the so-called stripping board and the free end of which is arranged in the opening and there is approximately aligned with the stripping surface in the said rest position.
  • the opening in the stripping board is usually shaped in accordance with the piece of waste to be removed therein; according to the invention, the opening arm, which is preferably directed transversely to its longitudinal axis, for receiving the spring, which, for example, is fixed at one end in a support profile running in the opening arm and with it the angle of inclination already mentioned certainly.
  • This support profile or its support section can either in turn be flush with the surface of the stripping board or run at a distance from it, which is a accordingly bring with it a different shape of the spring tongue, which can then optionally also carry a vibrating pin with it, which is coaxial with the stripping pin coming from above in the rest position.
  • the principle according to the invention is also realized by means of a rigidly rigid bearing surface which can be lowered at a distance from the break-out surface and can be adjusted to the angle of inclination described.
  • an angle piece which can be rotated about an axis and under the action of the restoring force of an energy accumulator, has proven to be particularly suitable.
  • axis rotatable roller-like body is provided, the periphery of which has a plurality of surfaces which are inclined to radii of the axis.
  • a roller is particularly suitable for this purpose, the cross section of which is structurally composed, for example, of a number of interlocking circles and which offers a circumferential groove through which the path of movement of the stripping pin is laid tangentially. It is also possible to place two disk-shaped rollers on the axis instead of the one roller with a circumferential groove, which have circumferential contours that are aligned with one another and between which the path of movement of the stripping pin lies.
  • At least one edge recess should extend from the free edge of the abutment, in particular the spring, as a lateral limitation of the path of movement of the stripping element or stripping pin.
  • a hole can be provided within the abutment surface, the width of which is greater than the cross section of the stripping pin or the like, so that this - as in the described edge recess - cannot come into direct contact with the spring surface on its way down. This requirement also significantly improves the discharge effect.
  • Cardboard sheets 10 used in the folding box industry have punched blanks for folding boxes or the like. on, in the blanks or on them waste pieces 12, 12 a arise.
  • the punched cardboard sheet 10 arrives after a punching station, which is not shown in the drawing for reasons of clarity, on a stripping board or a die 14 on which it is freed of its waste pieces 12, 12 a ; these are located above - depending on their contour - openings 16 in which, in the cross section of FIG. 2, an upper frame part 17 with a vertical wall is followed by a cone part that opens downwards.
  • the stripping board 14 has small edge zones of the waste pieces 12, 12 a , while other areas of edges 12 'of the waste piece 12, 12 a run at a distance within the contour of the opening 16 on the surface 15 of the stripping board 14. This gives rise to support zones R shown in FIG. 2 with a relatively high frictional resistance and areas of lower friction denoted by N.
  • break-out elements 20 in the form of a pin, or - in FIG. 1, 2 on the right, for example - as pressure cutters 20 s in a line-like manner, wherein differently designed break-out elements, not shown, can also be used.
  • the waste pieces 12, 12 a are separated from the cardboard sheet 10 and led away downward in the breaking-out direction x.
  • FIG. 3 shows a stripping tool with a clamping or lower pin 22, the surface of which lies against the lower surface of the waste piece 12 coaxially with the upper stripping pin 20, with which the waste piece 12 is held in a clamped manner and thus also leads out of the opening 16.
  • Figure 4 shows a typical multi-arm waste piece 12 t , on which - in accordance with the marked pressure points 20 '- eight break-out pins 20 act, of which only two (in FIG. 4: black points) are each supported on a coaxially provided lower pin 22.
  • the exemplary section from a stripping board 14 according to the invention according to FIGS. 5 to 8 reveals an approximately rectangular opening 16 for a waste strip 12 to be broken out, to which a breakthrough arm 24 connects transversely to its longitudinal axis M for receiving a step-shaped support profile 26; this is with a short bearing section 27 on the underside of the board 15 t at one end by means of screws 25 or the like. so determined that a - compared to the profile section 27 - longer support section 28 extends near the board surface 15 and the end edge 29 runs at a small distance b from the parallel opening edge 16 '.
  • a spring tongue 30 nestles, riveted or the like to this with its rear end region. attached and is otherwise resiliently pivoted downward from this.
  • a cranked upwardly directed bearing step 32 is formed at its free end, which is arranged in front of the end edge 29 of the support section 28 and is in the opening 16 in the rest position shown in FIG. 6 and its upper side with the surface 15 of the stripping board 14 approximately flees.
  • the free length i of the spring tongue 30 of approximately 35 mm corresponds in the selected exemplary embodiment to almost three times the thickness q of the stripping board 14 or the height of its opening 16.
  • the cone angle t from the cone part 18 of the opening 16 is more than 50 °.
  • the bearing step 32 of the spring tongue 30 has a part-circular recess 34 in the region of its free edge 33, within which the movement path of the stripping pin 20 determined by the pin axis A runs.
  • the spring tongue 30 in the embodiment of FIG. 10 is curved in cross-section like a loop between the bearing stage 32 and the fastening end and is fixed under the support section 28 of a U-shaped support profile 26 a , the transverse wall of which has a cutout 36 penetrated by the spring tongue 30; its edges limit the feather deflection.
  • a spring bolt 30 a crossing and holding at its bearing end 31 spirally rolled 30 a can be fixed.
  • a spring tongue 30 which is fixed at one end at a distance from the surface 15 of the stripping board 14 is bent upwards with its free part and folded to form a double-layered bearing step 32 d ; this training increases the elasticity of the device considerably.
  • Correspondingly folded free ends are also possible with approximately vertical lines projecting into the opening 16 spring tongues 30 v according to FIG. 14.
  • a clamping pin 22 which is spring-mounted in this way protrudes upwards from a spring tongue 30 h provided at a distance from the surface 15 of the stripping board 14 and ends slightly below the surface 15.
  • a roller 40 can be rotatably mounted in a stepwise manner in the opening arm 24 on a horizontal axis 28a, the cloverleaf-like or cross-shaped cross-sectional contour of which - here four - is composed of partial circles; the outer surface 41 of the roller 40 from bead strips thus formed form abutments for the stripping pin 20 or the intermediate waste piece 12 which can be moved downward against the force of a spring 42.
  • the roller 40 is otherwise provided with a central circumferential groove 44 for the passage of the pin axis A. .
  • two roller disks 40 a can also be fixed at a distance e from one another on the axis 38 a (FIG. 18).
  • the axis B of a clamping pin 22 a is inclined at an angle f of approximately 20 ° in a bushing 46 and the clamping pin 22 a is held in the gripping position shown by the force of a spring 48.
  • This clamping pin 22 a is equipped with a stop head 50, the surface 51 encloses an angle f with a radial to the axis B and extends approximately parallel to a fastening collar 52 of the sleeve 46.
  • FIGS. 20 to 22 offers, in the opening 16, an angle piece 58 which can be tilted to a limited extent against the force of an expansion spring 56 about an axis bolt 54 running parallel to the stripping board 14, one leg 59 of which extends on the surface 15 of the stripping board 14 and the other ( Bearing) leg 60 - optionally also a wing formation 61 - is penetrated by that axle pin 54.
  • the latter is mounted in flank walls 62 of a bearing block 64, which in turn is fixed by means of wing-like flanges 65 which engage under the stripping board 14.
  • the flank walls 62 are connected by a front transverse web 63 of the bearing block 64, in which a free end 55 of that spreading spring 56 is fixed; whose other radial end 57 sits below the axle pin 54 in the bearing arm 60.
  • FIG. 23 shows two approximately vertical leaf springs 30 v on both sides of the opening 16. These leaf springs 30 v flank a passage gap 66 (FIG. 24) which determines the path of movement of a stripping pin 20 s with a flat end edge or cutting edge. Such a passage gap 66 is limited according to FIG. 25 by resilient rubber noses 68 or brush-like inserts 70 (FIG. 26). Bristles 72 of the brushes 70 extend transversely to the pin axis A and are of decreasing length in the printing direction, so that they are able to serve as an abutment on the one hand and on the other hand allow the waste piece 12 to be guided downward.
