Definitions

  • the invention relates to a device for removing stripped parts, especially waste pieces, from a blank or the like. containing sheet of material, according to the preamble of claim 1.
  • stripping devices which are preferably provided in a set-up table outside the punching machine.
  • Such a stripping station is of particular importance for production, since if it is used incorrectly, it takes the largest 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 cutting edges which press from above.
  • the first step in the development of the stripping technique was the top tool pin, which pushes the waste piece 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 i.w. conical side walls have concave contours in cross section.
  • this tip hits the piece of waste, which, when placed on the breakthrough edges, opposes the tip with so much resistance that this tip can penetrate slightly into the material of the waste piece. This prevents undesired lateral evasion of the piece of waste.
  • a device according to the preamble of claim 1 has become known from DE-B-1 206 715.
  • This document shows a stripping device for a press for punching shaped pieces of paper or the like. According to this document, shaped pieces of paper are thus created, rather than broken pieces of waste from a sheet of material containing blanks, as is the case according to the invention.
  • a support frame made of rubber rests on the die.
  • This support frame has an opening that is smaller than the die opening. Both openings lie vertically one above the other.
  • the patrix i.e. the stripping element
  • the stripping device hits the fitting with the stripping device and cuts the connecting webs in the further downward movement, the elastic edge of the rubber support frame, as shown in FIG. 3 of this document, being bent downwards.
  • the elastic edge of the support frame according to this DE-B is therefore an abutment, which can be converted into a deflection angle to the material sheet when the molded part is moved by the stripping member there when the molded part is lowered into a deflection angle.
  • the abutment according to this DE-B-1 206 715 is therefore part of a rubber pad, wherein rubber has the usual signs of aging. It must be assumed that the elastic edge of the support frame 19, which is bent downward when the shaped piece 12 broken out according to FIG. 3 breaks off, only snaps back into its old position to a limited extent in order to hold a new shaped piece 12 for the next breaking-out process .
  • the rubber bearing frame 19 must often be replaced with certainty.
  • 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 is fixed at one end therein, for example on 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 aligned with the surface of the stripping board or can run at a distance from it, which can result in a correspondingly different shape of the spring tongue, which then also, if appropriate can carry a vibrating pin that is coaxial with the stripping pin coming from above in the rest position.
  • the principle according to the invention is also realized by a rigid bearing surface, which can be lowered at a distance from the break-out surface and can be adjusted in the described angle of inclination.
  • An angle piece which can be rotated about an axis and is under the action of the restoring force of an energy store, has proven to be particularly suitable for this purpose, which preferably bears in a bearing block of the stripping board and offers a leg as an abutment.
  • axis rotatable roller-like body may be 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, structurally, consists, for example, of a plurality 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, instead of one roller with a circumferential groove, to place two disc-shaped rollers on the axis, which have circumferential contours which 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 movement path 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 comes after the sake of clarity is not shown in the drawing, punching station to a stripping board and a template 14 on which / is freed of the cardboard sheet from its waste portions 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 18 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 results in support zones R shown in FIG. 2 with a relatively high frictional resistance and areas of lower friction designated with 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 guided away downward in the breaking-out direction x.
  • FIG. 3 a stripping tool with a clamping or lower pin 22 is shown, the surface of which rests on the lower surface of the waste piece 12 coaxially with the upper stripping pin 20, holds the waste piece 12 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 of a stripping board 14 according to the invention according to FIGS. 5 to 8 shows 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 stepped shaped support profile 26; this is with a short profile section 27 on the underside of the board 15 t at one end by 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 cranked upward-facing 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 which, in the rest position shown in FIG. 6, is in the opening 16 and the upper side of which is approximately flush with the surface 15 of the stripping board 14 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 cut-out 36 penetrated by the spring tongue 30; the edges of this cutout 36 limit the spring deflection of the spring tongue 30.
  • a spring bolt 30 a which crosses and holds at its bearing end 31 in a spiral manner and which holds axles 38 can be fixed.
  • edge recess 34 instead of the edge recess 34 described here - as is also possible in other examples - there is an elongated hole 34 n at a distance from the free edge 33 through which the movement path of the stripping pin 20 leads.
  • a spring tongue 30 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 into 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 spring pin 30 resiliently mounted in this way protrudes 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 supported in a stepwise manner in the opening arm 24 on a horizontal axis 38a, the cloverleaf-like or cruciform 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 which can be moved downward against the force of a spring 42 for the stripping pin 20 or the intermediate waste piece 12.
  • 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 or lower 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 of which encloses the angle f with a radial to the axis B and extends approximately parallel to a fastening collar 52 of the sleeve 46.
  • the embodiment according to FIGS. 20 to 22 offers in the opening 16 an angle piece 58, which can be tilted to a limited extent against an axis bolt 54 running parallel to the stripping board 14 against the force of an expansion spring 56 and whose one leg 59 runs on the surface 15 of the stripping board 14; the other (bearing) leg 60 - possibly also a wing 61 - is penetrated by that axle 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.
  • a passage gap 66 can be 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 downwards.
