Definitions

  • lids made of very thin and light material such as heavily rolled aluminum or aluminum-laminated nylon foils, etc.
  • the present invention was based on the object of designing a method and a device which is suitable for carrying out this method and which also allows very light and possibly less area-stable materials to be used as cover material without the risk having to be accepted that on the The relative position of the lid relative to the container changes from the punching point to the sealing point.
  • This object is achieved by a method of the type mentioned in the introduction, in which the container and the film are connected to one another at the punching point.
  • the main task was to connect the connecting means to the punching device in the simplest possible and space-saving manner. This is achieved through within a punch Tool and co-axially movable means for making this connection.
  • This film designates a die formed as a base plate, against which a film 3 can be clamped by means of the hold-down device 2 which can be actuated in a manner not shown.
  • This film consists of the thermoplastic material on the underside of the closing element, which is intended to be placed on the upper edge 4a of the cup 4 and to be hot-sealed with it in a further station, not shown.
  • This material can be thin aluminum, plastic laminated with aluminum or another thin material suitable for an airtight seal.
  • the hold-down 2 has a circular opening 2a arranged co-axially with the die opening la, into which the combined punching and stapling tool 5 can enter.
  • This tool 5 essentially consists of a punch 6 designed as a punching device, which is designed in its lower part as a bell, which comprises both the most essential parts of a stapling device 7 and an ejector 8.
  • the three parts, punching device 6, stapling device 7 and ejector 8 are arranged co-axially with respect to one another and can be moved up and down at right angles to the film 3 within the opening 2a of the hold-down device 2 in a manner not shown further. It is not critical whether the stapling device 7 and the ejector 8 are used individually or only together. are movable over the punch 6.
  • the punching device 6 consists essentially of an actuating tube 6a and one at the bottom of this tube 6a adjoining bell 6b, the edges 6c of which are designed as punching tools.
  • the actuator tube slidably supported 7a of the stapler 7 which also has a lower from that of the punching device comprised 6 bell, 7b, along the edges thereof in - 9 are arranged spaced from each other, micro-resistors, wherein the power supply to these micro-resistors 9 through the pipe 7a and is not shown in the drawing.
  • the actuating rod 8a of the ejector 8, through which a channel 10 passes, is held within the tube 7a, which rod 8a carries at its lower end an ejector plate 8b within which a number of suction channels 11 communicating with the channel 10 are provided.
  • the channel 10 is connected at its upper end to a vacuum source in a manner not shown.
  • the three elements 6-8 are lowered through the opening 2a onto the film 3, the edge 6c of the punching device 6 protruding downward beyond the stapling device 7 and the ejector 8 and being formed as a punching tool, and from the film 3 cut out a circular lid.
  • the ejector 8 is lowered until the ejector plate 8b rests on the top of the film, its central channel 10 being connected to the vacuum source, so that after the cover has been punched out, the ejector 8 sucks it in and pulls it on the bottom of the ejector plate 8b sticks.
  • the ejector 8 is then lowered jointly with the stapling device 7 until the ejection is complete punched lid rests on the edge 4a of the container 4, the last of which is brought into a position below the die opening 1 a by a schematically indicated transport device 12, as shown in the drawing.
  • the micro-resistors 9 therefore rest on the edge 4a of the cup 4, so that when the feed current line to these micro-resistors 9 is closed, a point-like connection between the lid punched out of the film and the container rim 4a takes place by thermal welding.
  • the punched-out lid film is now connected at certain points to the container edge 4a, so that a change in the relative position of these two elements during the further transport of the cup 4 from the punching point shown in the drawing to the. is no longer possible from the sealing point that is not apparent from the drawing.
  • the high-precision punching tool is not impaired by the effect of heat, which cannot be avoided during the final sealing.
  • the heat generated by the micro-resistors is comparatively low and, on the other hand, thanks to the relative mobility of the stapling device with respect to the punching device, it takes place at a location that is last removed from it.
  • a number of micro resistors are used for stapling.
  • the first group includes, for example, heated pens, ultrasound exciters, etc.
  • the second group primarily includes gluing or local mechanical deformation using a lowerable deformation tool. All of these tacking means serve to establish a punctiform connection between the cover film and the container edge, in order in this way, during the further transport of the cup, a relative movement of the film relative to the cup, respectively. to avoid corrugation of the film edge caused by moisture, electrostatic forces or other influences.
