Definitions

  • the subject of the invention is a punching machine for punching labels and lids according to the preamble of claim 1.
  • the invention also relates to a method for controlling the advance of the punch according to claim 24.
  • the punching of labels and flat lids is known and takes place in different ways.
  • the labels and lids which consist of paper, cardboard, metal foils or laminated materials such as metal and plastic materials, can be produced by a punching process with a linearly driven punch or, on the other hand, between two rotating drums.
  • the method described here comprises only the punching with a punch against a die and in particular the punching of labels and lids from starting material fed in endlessly in the form of a strip.
  • the strip-shaped material is unwound or pulled off a coil and passed between the punch and the die.
  • the tape lifters only guide the tape in one direction. Tape lifters only ensure a minimum distance between the tape and the die, but the distance between the tape and the punch is not influenced by the tape lifters.
  • One object of the present invention is to create a punching machine which enables perfect, uninterrupted punching and which In particular, a proper advance of the film to be punched to and in the punching device is guaranteed and then a proper removal of the unstable lead frame is guaranteed. In addition, the aim is to create the possibility of leading the lead frame through the punching device and also out of it again without interference.
  • Another task is to be able to set and adjust the time course of the punching stroke at any time, in particular the time course of the entry and exit
  • Another object of the invention is to create a method with which the course of the punching stroke can be adapted to the properties of the film.
  • the servo motor allows the time course of the punch from the rest position to the working position or its end after the immersion and cutting of the
  • the rigid connection of the two components creates a guide system with a large guide distance, which practically does not allow any deformation and thus ensures a uniform cutting gap between the punch and die (2-3 micrometers gap).
  • the system of a tool slide with a rigid connection between the tool slide / tool and a free-flying tool is unique and offers great advantages in terms of accessibility in the tool area and a precise and stable guide system.
  • the feed device comprises two interacting rotatably driven rollers with a jacket made of rubber or another covering having a high coefficient of friction.
  • axially spaced apart magnets are used. These cause the contact pressure between the two interacting rollers to be constant over their entire length, ie between the bearing points, so that the film can be fed to the punching device without slippage at an exactly predetermined speed.
  • the distance to the opposite shaft or a ferromagnetic core located in the opposite shaft can be adjusted and / or adjusted the force of attraction and thus the surface pressure of the two rollers by rotating the shaft can be set.
  • toothed wheels are attached, over which a toothed belt, preferably a toothed belt with teeth attached on both sides, rotates. Due to the partial wrapping of the two gears at the same time, they are driven at exactly the same peripheral speed. This increases the accuracy of the advance of the film and, in particular, a distortion-free advance over the entire width of the
  • Two pairs of conveyor rollers can each be rotatably mounted in a common axis or the axially opposite pairs of conveyor rollers are arranged at a slightly acute angle so that they always pull and tension the film outwards during transport.
  • the bearing housings of the conveyor rollers can be raised or lowered perpendicular to the base plate in order to increase the distance between the foil and later the lead frame to the die and the punch and thus additionally prevent the lead frame from getting caught in the punching device when it is pulled away from the punching device .
  • the linear guides with roller cages are preferably mounted so as to be vertically displaceable.
  • a first deflecting roller is mounted so that it can be displaced essentially perpendicular to the transport direction between a second pair of take-off rollers arranged following the punching device, seen in the working direction, which, like the first pair of take-off rollers, can be formed in front of the punching device.
  • the amount of the respective shift due to voltage changes or changes in conveyor speed is measured by a position encoder.
  • the take-off speed can be regulated in order to guide the latter taut on the entire transport path of the film and then the lead frame.
  • the pulleys, over which the lead frame is guided after the punching process, are mounted in bearing blocks which are mutually displaceable on guide profiles in order to adapt the clamping gap to the thickness of the foil or lead frame.

  • the essential elements of the punching machine 1 include a main drive 7 with a servomotor 9, a spindle 11, a guide element such as a tool slide which guides the punch 13 linearly in the direction of a die 57 on a base plate 15
  • the punching material hereinafter referred to as film 19 for short, is fed to punching machine 1 from a coil 21.
  • the film 19 is pulled off the coil 21 with the feed device 17, which can be preceded by a dancer (FIGS. 5 to 10).
  • the feed device 17 comprises two rollers 29 arranged on parallel axes, which preferably have a rubber coating or jacket 41 on their periphery, which ensures a slip-free feed of the film 19. At least one of the two rollers 29 can be driven by a drive motor 53. Both rollers 29 are preferably driven synchronously.
  • the two rollers 29 comprise a shaft 37 on which a plurality of axially parallel arranged in a row
  • Magnets 33 are arranged in bores 35 extending radially to the axis.
  • the magnets 33 can also be attached to the surface of the shaft 37.

  • rollers 29, which are thin in relation to their axial length, are driven by the non-co-rotating shafts 37 arranged in their center or by the shafts 37 arranged thereon
  • Electro or permanent magnets 33 are mutually attracted. In this way, over the entire axial length achieve a uniform, mutual pressing of the peripheries of the rubber jackets 41. This uniform, mutual attraction of the rollers 29 extending over the entire axial length is retained, regardless of the thickness of the film 19, which is passed between the two rollers 29 and conveyed. The change in the center distance between the two rollers 29 due to foils 19 of different thicknesses is absorbed by shifting one of the rollers 29 on the guides 49 on which the second shaft bearing is mounted so as to be radially displaceable.
  • the power of mutual attraction can be adjusted.
  • the shafts 37 are attached to the bearing block 45 so that they can rotate through a certain angle of rotation, so that the radial distance between the magnets 33 on the shafts 37 can be adjusted. If the magnets 33 lie opposite one another on the two shafts 37 exactly between the axes of rotation of the rollers 29, then there is the greatest force of attraction; if they are rotated by a few degrees, the mutual attraction decreases accordingly.

  • the film 19 drawn off from the coil 21 by the feed apparatus 17 then passes into the punching device 5, ie between the punch 13 and the base plate 15 with a die 57 (FIG. 11).

  • the film 19 is consequently held by four pairs of conveyor rollers 63 during the punching process, on the one hand when the film 19 is stationary and on the other hand when it is being transported. As a result, it cannot contract lengthways, crossways or diagonally.
  • the lead frame produced after the punching is consequently always kept taut when the film 19 is moved out of the punching area. Even if the greater part of the
