Definitions

  • the invention relates to a method and a device for punching labels, in particular neck labels or similar punched material made of paper, plastic films or the like.
  • the punching of labels takes place in a punching machine in which a stack of mostly rectangular pre-cut pieces of material is pressed from below against the cutting edge of a frame-shaped punch knife, in particular open at the top and bottom.
  • the interior formed by the side walls of the frame-shaped punching knife has the final shape of the material to be punched, the lower edge of the side walls being the cutting edge of the punching knife and the side walls widening in a wedge shape from the cutting edge upwards and outwards so that the punching knife increases the considerable amount that occurs during punching Can endure forces.
  • the final shape of the punched material can thus be recorded in the interior of the punching knife having vertical wall surfaces, while the outer edges of the pre-cut punched material accumulate as waste outside the side walls of the punching knife and can be removed in a simple manner.
  • the type and structure of known punching machines enable the punching of labels with simple outer contours, such as, for example, square, oval, rounded, bordered labels or punched material, the final shape of which can be easily accommodated inside the punching knife.
  • Cutouts with narrower points between the cutout edges at the cutout mouth compared to cutout widths inside the cutout are particularly desired by the beverage industry for neck labels for bottles, in particular in order to be able to provide the bottles with more elegant neck labels with the same extensive, printed information content.
  • the well-known neck labels are usually so large because of the desired amount of information that they appear "plump" and cover a very large part of the bottle surface.
  • the object of the invention is to provide punched material of the type described at the outset with cutouts, in particular with undercuts, in a simple and economical manner, the known punching devices with the proven punching technology being used.
  • the method according to the invention starts out in a manner known per se from square, pre-cut die-cut sheets 1, which are combined in a stack 28 and have the side edges 2, 3, the top edge 4 and the bottom edge 5.
  • a label 15 with contours symmetrical to the center line (FIG. 3)
  • identical cutouts 6, 7 are directed into the sheet 1 with a correspondingly shaped frame-like shape, the punched product in its interior positively receiving, indentations for the cutouts having punch knife 21 and the resulting scrap 8 immediately after the cut laterally in the direction of the arrow 9 pulled out. In this way, the pre-punched intermediate punch product 11 is created.
  • Each cutout 6, 7 has, starting from the cutout mouth 10 on the side edge, cutting edges 12, 13 which run into the interior of the sheet and merge into an end cutting edge 14.
  • the cutting edges 12, 13 are expediently arranged to converge somewhat from the mouth 10, whereby the pulling out of the waste piece 8 is promoted.
  • the angle of convergence is adapted to the shape and size of the cutout, the area of the waste piece 8 being chosen to be as large as possible, so that the greatest possible free space is created by the cutout 6,7.
  • the cut edges 12, 13 can also run at least partially parallel to one another or even somewhat diverging towards the end cut edge 14, provided that and insofar as the removal of the waste piece 8 is not hindered.
  • each piece of waste 8 of a sheet of cut material 1 arranged in the stack is removed immediately after the cut, so that the waste pieces of the stack do not hinder the progress of the punch in the indentations tapering upwards.
  • the stack with the precut die-cut sheets 1 is pressed from below against the cutting edge of the correspondingly shaped, frame-shaped die-cutter, which positively accommodates the die-cut material in its interior, and is continuously pushed upwards, thereby effecting the punching process.
  • edges 8a are cut off from the side edges 2, 3, the upper edge 4 and the lower edge 5, so that the edges 8a can still be connected to the waste piece 8.
  • the intermediate punch product 11 accordingly has shorter side edges 2a, 3a, a short front edge 4a and a shorter rear edge 5a.
  • the cutting off of the edges 8a is problem-free because, on the one hand, this edge material has sufficient space on the outside of the knife to be displaced there and, on the other hand, it is transported away together with the waste piece 8 can.
  • a punching is carried out with at least one punching knife 36 arranged on the outside of the punching knife, which executes a possibly leading, short punching cut 16, starting from the lower edge 5 and / or the upper edge 4, in the edge width.
  • a punching knife 54 which is also frame-shaped and has at least one punching knife, serves for this purpose, the inner contour of which has the label contour and the outer contour of which has corresponding indentations in the region of the cutouts.
  • the final die-cut shape of the neck label 15 shown in FIG. 3, for example, has an upper label band 17, a lower label band 18 and a narrow central web 19 connecting the bands 17, 18.
  • the space between the bands 17, 18 next to the central web 19 is a free cut 6a, 7a, which has a free cut mouth 10a, from which cut edges 12a, 13a diverging from one another to the end cut edge 14a, which results in an undercut free cut 6a, 7a, the width of the mouth M is smaller than its greatest width B behind the free cut mouth 10a.
  • the device in particular for carrying out the method described, has, apart from the special spatial shape of the pre-punching knife 21 and a clearing device 22 for each cutout 6, 7 a conventional structure and has an upper abutment 23 with a central hole 23a, including a table top 25 with a central hole 26 and a stacking bearing plate 24 in the region of the hole 26.
  • a force generating device for example a piston-cylinder unit 27, is arranged under the stacking bearing plate 24 and can move the stacking bearing plate 24 in the double arrow direction 28, wherein the stacking bearing plate 24 can pass through the hole 26.
  • a stack bearing plate 24 On the stack bearing plate 24 is a stack of material to be punched 28, on which the punching knife 21 is arranged, which is supported during punching with its upper edge 30 against abutment cantilever arms 29 against which it is pressed indirectly by the piston-cylinder unit 27.
  • the abutment cantilever arms 29 are arranged on the upper abutment 23, which thus intercepts the punching forces.
  • the frame-shaped pre-punching knife 21 has the side walls 31, 32 as well as the upper edge wall 33 and the lower edge wall 34.
  • the walls 31 to 34 run downwards in a wedge shape in a cutting edge 35 seated on the stack of material 24, the inner wall surfaces of the walls 31 to 34 being aligned vertically.
  • a punching knife 36 is provided on at least one outer wall surface, expediently on the outer surface 34 and / or 33 in the context of the invention.
  • the interior 37 of the pre-punching knife 21, which has vertical inner wall surfaces, has the cross-section of the contour of the intermediate punching product, i.e. during punching, an edge region 8a of the stack 28 is punched away as waste, while the material to be punched is positively received in the interior 37.
  • the punching device corresponds in construction to a conventional punching machine.
  • a punch knife 21 with U-shaped indentations 38 which extend from the side walls 31, 32, extend into the interior 37 and have the indentation side webs 39, 40 and the indentation base web 41.
  • the Indentation webs 39, 40 run from indentation base web 41 parallel to one another, preferably slightly diverging.
  • the webs 39, 40, 41 like the walls 31 to 34, have vertical surfaces on the inside and outer surfaces running wedge-shaped to the cutting edge 35 on the outside.
  • a clearing device 22 is provided for the controllable removal of the waste pieces 8, possibly with the edge 8a, immediately after the punching of the corresponding sheet belonging to the waste piece 8 or edge 8a in the stack 28.
  • An expedient clearing device consists of a vertically oriented, narrow, endlessly guided clearing band 42, the surface 43 of which is roughened, in particular provided with teeth.
  • the clearing band 42 is so narrow that it fits loosely into the indentations 38.
  • the front contact area in particular the front area of the front deflection 45 of the inclined broach 42, protrudes into the indentation 38 and lies on the surface of the stack 28 in some areas.
  • the rear, higher-lying area of the broaching band 42 is arranged outside the indentation 38, the rear deflection 44 being coupled to a drive motor 46 which is supported on the table top 25 with a bearing block 47.
  • the broaching band 42 engages with its central region through a slot 48 of a vertical wall 49 of a broaching plate 50 designed as an angled plate, the horizontal wall 51 of which rests on the table top 25 and is directed against the punching knife 21.
  • the broaching plate 50 is longer than the punching knife 21 is wide, the projecting area having a downward slope 51a.
  • the clearing band 42 is thus arranged above the horizontal wall 51.
  • a blower 52 is installed, which is directed into the clearing alley formed by the clearing plate 50 (arrow direction 53 in FIG. 4).
  • the clearing belt 42 is expediently spring-loaded (not shown) in such a way that the contact area of the clearing belt not only with the dead weight on the waste piece 8 or the stack 28, but instead with an additional force.
  • the speed of the clearing belt 42 driven in the direction of the arrow 53 can be regulated and adjusted to the punching speed in such a way that the waste pieces 8 are cleared away immediately after they have arisen, the clearing belt 42 pulling the waste pieces 8 out of the indentation 38 and the blower 52 then blows the waste pieces out of the machine through the clearing alley of the clearing belt 50 via the slope 51a.
  • a post-punching knife 54 which also has indentations 55, is used in a different or the same basic machine to determine the final shape of the punched product, e.g. the label 15, ready to punch (Fig. 7).
  • the bulges 55 are so wide that the waste edges can be freely displaced into the indentations and removed in the usual way. Waste disposal does not require a special clearing device.
  • the clearing device 22 according to the invention can also be used expediently during re-punching in order to accelerate the removal of the waste in a controlled manner.
