Definitions

  • the invention relates to a device for punching a hole in a paper web, in particular for the production of liquid packs, with a movable punch with circular pressure which can be guided against a counterplate. the knife at its tip.
  • packs with punch holes are known, in particular packs for liquid beverages made of paper coated with plastic.
  • the punched holes in the paper web of such packs are used to pierce a straw.
  • the aim of the manufacturer of such packs is to pre-punch the hole in the paper web in such a way that, on the one hand, the pack is or remains tight and, on the other hand, the user can easily pierce it using the straw.
  • the stamping dies instead of the subsequent coating of the completely punched-out paper web, attempts have been made to use the stamping dies on paper webs that have already been coated on both sides. If you go e.g. from a paper thickness of 0.4mm, including the plastic coatings; then the thickness of the outward facing plastic coating is e.g. 0.01 mm, while the plastic layer to be placed inside has a thickness of 0.04 mm.
  • the punching knife should completely punch through the outer thin layer and the paper layer arranged between the two plastic layers, while the plastic coating on the inside should remain intact so that the tightness is not endangered. In the example mentioned above, this means that the punching knife has to be pressed so deep into the coated paper web that the punching depth is 0.35 mm.
  • the object of the invention is therefore to provide a device of the type mentioned at the outset, which enables the desired hole to be punched into the desired depth with simple means.
  • the object is achieved in that the punch has a rotatably driven cutting head.
  • the basic idea of the invention lies in the movement of the punch or the edge forming the knife at its tip, so that it is not only pressed into the paper web as in the previously usual pure punching process, but is moved perpendicular to this direction of movement, thereby creating a cutting effect like when using a knife. With this measure, the desired hole is cut, and it is even possible with advantage to insert holes of larger diameter in paper webs in exact cutting depth and over the entire circumference of the same punching or cutting depth.
  • Suitable carrier beams can be selected, preferably those at the embossing station, so that additional control devices are omitted, which cause increases in price and susceptibility to faults in the known devices.
  • the cutting head is held in an outer carrier and can be adjusted and locked relative to this by means of an adjusting nut in the axial direction.
  • the adjusting nut is therefore rigidly connected to the cutting head, e.g. by a screw connection, and is supported with its end face against the outer support, which holds the cutting head.
  • This support takes place via a friction clamping surface, which is preferably located on the outer carrier mentioned and against which the adjusting nut can be firmly locked by suitable means, preferably clamping screws.
  • the cutting head is detachably attached to a drive shaft.
  • the cutting head carrying the knife is therefore advantageously exchangeable as a wearing part and is held by its fastening means in the drive shaft, for example a correspondingly secured screw connection, so that the cutting head is carried along by the drive shaft.
  • the drive shaft in turn is connected to a motor that intermittently or continuously rotates them during the punching process.
  • the hollow drive shaft which is preferably held in an adjustable bearing cylinder via ball bearings, is kept free of play in the direction of its axis. This can be achieved, for example, by a nut with a lock nut placed above it.
  • the cutting head and the drive shaft are hollow, the cavities are flush with one another, and the drive shaft is provided with at least one radial bore at its rear end facing away from the cutting head tip.
  • this piece of cardboard can move backwards through the cavities, which are preferably designed as bores, in the cutting head and further back in the drive shaft and through one or several radial holes (holes) are discharged to the outside.
  • the circular knife at the tip of the cutting head is preferably designed such that, according to the invention, a circular edge is formed, which is defined by the cutting line between the cylinder of the central bore forming the cavity of the cutting head and one of the cone extends backwards.
  • a circular edge is formed, which is defined by the cutting line between the cylinder of the central bore forming the cavity of the cutting head and one of the cone extends backwards.
  • One surface behind the circular knife edge is therefore a cylindrical surface which surrounds the central bore, and the other surface behind the circular knife edge is a truncated cone surface, the truncated cone moving backwards from the tip of the cutting head, ie from the Paper web continued, expanded.
  • This configuration of the cutting head tip causes friction to be applied to the correct surface parts: the greatest friction occurs with such a cutting head knife on the truncated cone surface described.
  • the greater the pressure the greater the radius of the truncated cone surface.
  • the lowest friction results in this knife according to the invention in the area of the cylindrical surface, ie on the circumference of the central bore.
  • the paper middle part can be least torn off from the point of adhesion, preferably from the opposite plastic, by the penetration of the knife with the central bore.
  • the round middle section remains in the paper web.
  • An exact cutting depth can be provided in a particularly favorable manner in that, according to the invention, the outer carrier holding the cutting head can be pressed against a resiliently mounted plate of large surface area.
  • the counterplate mentioned at the beginning, against which the punch or cutting head is pressed, rests on at least one compression spring which acts in the direction of the lifting movement of the punch (for performing the punching or the cut) and thus in the direction of the longitudinal axis of the hollow drive shaft and Longitudinal axis of the cutting head is compressible.
  • the punching device is arranged on the support bar of an embossing station or the resiliently mounted plate is provided on the opposite part of the bar.
  • the resilient mounting of the counter plate gives the punching device the option of performing the punching before the stamping.
  • the distance between the spring-loaded plate and the outer carrier ie those two surfaces which lie opposite one another in the punching device and between which the paper web to be punched is passed and clamped, determines the depth of penetration of the knife into the paper web.
  • the paper web is clamped between the outer support or its front-side contact surface and the spring-loaded plate (single-layer or double-layer, depending on the requirements) as the one or more springs allow.
  • the area of the spring-loaded plate is chosen to be large in relation to the hole to be punched, because it eliminates fluctuations in paper thickness.
  • a scale can also be expediently attached to the adjusting nut, which cooperates with a pointer attached to the outer carrier for the cutting head and drive shaft. In this way you get a simple indication of the cutting depth because the scale can be calibrated in cutting depth.
  • FIGS. 1 and 2 show a punching device with a punch bar on the punch punch side, which is arranged in the area of the stamping station indicated in FIG. 1 and generally designated 1 with the two stamping plates 2 and 3 (on the right in FIGS. 1 and 2) and a support bar 5 on the counter plate side (on the left in FIGS. 1 and 2).
  • the outer support 6 is fastened with its end-face contact surface 7, while on the opposite support beam 5, the support bracket 8 for the spring-loaded plate 9 is attached.
  • the embossing plates 3 and 2 are also fastened to the support beams 4 and 5. These are provided with embossing devices (bulge and channel) at the locations marked with 10.
  • the spring-mounted counter plate 9 is guided by two screws 11 and supported against the compression spring 12. As a result, it has the possibility of moving in the direction of the double arrow 13 shown in FIG. 2, although the support bar 4 or 5 or both also has the possibility of moving in the direction of the double arrows 14 shown. It can be seen that at least in one direction (perpendicular to the paper plane in Fig. 1 and from top to bottom in Fig. 2 in the paper plane) the spring-mounted plate 9 has a large surface area, in particular in relation to that in the Paper web 15 hole to be punched.
  • the outer support 6 is fastened, which is open on one side towards the rear, forms the contact surface 7 on the front on the front side and is provided in the middle with a further opening through which the cutting head 16 can protrude in front of the contact surface 7.
  • an adjustable bearing cylinder 18 is arranged displaceably in the direction of the longitudinal axis 19 of the entire arrangement.
  • the adjustable bearing cylinder 18 is also hollow on the inside and holds the ball bearings 20, which are arranged at a distance from one another in the axial direction 19, for the concentrically arranged and supported hollow drive shaft 21, in the front end of which the cutting head 16 is screwed in, and the rear end of which via the coupling 22 is attached to the drive shaft of the motor 23.
  • the two cylindrical cavities 26 and 27 which are arranged coaxially in the cutting head 16 and are in alignment with one another are in alignment with the cylindrical cavity 28 and are therefore in connection therewith, which as a central bore along the axis 19 in the drive shaft 21 is arranged. Furthermore, the radial bores 24 are connected to the cylindrical cavity 28, so that in operation, pieces of paper punched out of the paper web 15, which should, contrary to expectations, be torn off every now and then, can reach the outside in the manner just described of the interconnected cavities .
  • the motor 23 is fastened to an elongated motor mounting plate 31 via screws 29 and sleeves 30.
  • this motor mounting plate 31 is firmly attached, so that when moving along the axes 19 to the front (in FIGS. 1 and 2 on the left) or to the rear (in FIGS. 1 and 2 to the right), motor 23 with Sleeves 30, motor support plate 31, bearing cylinder 18, drive shaft 21 and cutting head 16 can be moved. So that this displacement in the direction of the axis 19 can be carried out properly and precisely, the adjustable bearing cylinder 18 is clamped absolutely free of play against a movement in the direction of the axis 19 via the ball bearings 20, a spacer 32 and two nuts 33 placed one behind the other.
  • the adjustment itself is carried out with the aid of the adjusting nut 34, on which a scale 35 shown in FIG. 2 is provided for the interaction with a pointer 36 on the outer carrier 6.
  • the above-described unit consisting of motor 23, adjustable bearing cylinder 18, drive shaft 21 and cutting head 16 is moved forwards or backwards in the direction of the axis 19 (left or right in the drawings).
  • the adjusting nut 34 acts the friction clamping surface 37 on the outer carrier 6 and is clamped on the other hand via the locking screws 38. In this way, the tip 40 of the cutting head 16 can be adjusted to protrude the desired distance beyond the contact surface 7 of the outer carrier 6.
  • the tip 40 of the cutting head 16 which e.g. rotates in the direction of arrow 39 and is pressed into the paper web 15 with the outer plastic layer 41, the carrier material made of paper 42 and the inner plastic layer 43 while cutting.
  • the circular knife at this tip 40 is formed by the circular edge 44, which is formed by a cutting line which results when the cylinder of the central bore forming the front cavity 26 of the cutting head 16 is cut with a cone which extends from the tip 40 extended backwards (upwards in FIG. 3) so that the truncated cone surface 45 results.
  • the support beams 4 and 5 move apart, the paper web 15 is conveyed from top to bottom and inserted between the dies 2 and 3 and the contact surface 7 and the surface of the spring-mounted plate 9 opposite this. If the support beams 4 and 5 are now moved towards one another, the single-layer or two-layer paper web 15 initially comes into contact with the resilient surface of the resilient surface, pushed against the contact surface 7 of the outer carrier 6 mounted plate 9, which evades the compression of the spring 12 in FIGS. 1 and 2 to the left.
  • the motor 23 sets the drive shaft 21 with the cutting head 16 in rotation according to arrow 39 in FIG. 3 and in doing so carries out the cut to the desired depth, as shown in FIG. 3. It can be seen from FIG.
  • the cutting head 16 moves out of the position shown in FIG. 3 by moving the support bars 4 and 5 apart again.
  • the tip 40 of the cutting head 16 protrudes just as far in front of the contact surface 7 of the outer carrier 6 as is to be made in the operation mentioned above, i.e. e.g. by 0; 35 mm if the example mentioned at the beginning is used.
  • the depth of cut is determined by the distance between the resilient plate 9 and the outer support 6 or its front contact surface 7. At this distance, the knife edge 44 can penetrate the paper web 15.
