Definitions

  • the invention relates to a method and an apparatus for the disposal of flat problem material.
  • This is to be understood as material that cannot be easily reused and whose disposal causes problems.
  • An example of this are lead frames that are left over after stamping out adhesive labels. These lead frames have coherent longitudinal and transverse webs. They consist of paper, cardboard, aluminum or plastic film, but are always coated with a self-adhesive material. So far, the lead frames, wound up in rolls, can only be brought to a landfill. Disposal at landfills is expensive and will only be possible to a limited extent for commercial waste of this type in the future.
  • waste-to-energy plants need high-energy material to maintain a support fire during the night.
  • the material is interesting for thermal recycling there because of its high energy content, but not in the form of poorly flammable, solidly bonded rolls.
  • the object of the invention is therefore to provide a method and a device which convert problem material in such a way that it can be readily used for thermal recycling, in particular in a waste-to-energy plant.
  • the handling of the material at the point of origin should be automated.
  • leadframes and their parts usually get caught in processing machines.
  • the present invention is intended to solve the problems described above.
  • the width of the longitudinal strips can be selected so that subsequent transport by air flow in a tube is possible.
  • the resulting granulate can be transported automatically in a central disposal system and can also be sent to a waste incineration plant, since its surface / space ratio is particularly high, in contrast to glued rolls of lead frames, where the flames have practically no access to the interior.
  • the large numerical ratio mentioned is therefore an essential prerequisite for combustion without the addition of further fuels.
  • the remaining longitudinal strips are conveyed, preferably by an air stream, through a tube from the slitter to the cross cutter.
  • the width of the longitudinal strips can be selected so that when they are subsequently transported in a tube, cross webs remaining due to air flow get caught on at least one longitudinal web.
  • a device for carrying out the method contains, in addition to knives for the longitudinal and transverse cutting, above all an application station which serves to dispense the lubricant, in particular oil.
  • the granules can be fed to a press container, again from an air stream, by means of further pipes, whereby the transport volume is reduced.
  • FIG. 1 shows two printing presses 2, which print labels within a web running from a roll and punch out the labels. A then remaining lead frame 4 of z. B. 50 cm width is subtracted upwards. Three labels were printed next to each other, so that the lead frame has three approximately rectangular openings next to each other.
  • the leadframe consists of four longitudinal bars (perpendicular) and cross bars arranged at right angles to them. The lead frames 4 are each fed to a slitter 6, as shown in perspective in FIG. 2.
  • the slitter has cooperating pairs of conveyor rollers 8, which pull the lead frame in the direction of arrow 10, past an application station 12, which applies a lubricant, in particular oil, to the lower side of the lead frame without contact.
  • the application station has a flat storage container 12.1 below, which holds the liquid lubricant 12.2.
  • a freely rotatably mounted metering roller 12.3 is partially immersed in the lubricant, takes along lubricant on its surface during its rotation and transfers it to a roller provided with radial, elastic bristles (brush roller 12.5). The brush roller is driven in the direction of an arrow 12.6.
  • a scraper 12.7 which runs over its entire length and which projects so close to the brush roller that the bristles are bent as the brush roller rotates and then snap back upwards. Doing so the lubricant adhering to the bristles is thrown in fine droplets against the lower surface of a lead frame drawn over it. The lubricant is therefore applied without contact between the bristles and the lead frame.
  • the lubricant may be easier to apply, such as spraying or rolling.
  • the lead frames are pushed into pairs of interacting, rotating cutter disks 14 by the conveyor rollers 8.
  • An air flow guided in the running direction of the lead frame acts as a support.
  • the cutter disks 14 can be moved and locked in the direction of their drive shaft. They are set so that they cut through the crossbars of the lead frames. If you do not want individual crossbar pieces, only one pair of knife disks can be effective between two longitudinal webs.
  • FIGS. 3 and 4 show the cross cutter in two mutually perpendicular cuts, both in the longitudinal direction of a tube 26 containing the cross cutter.
  • the cross cutter has three knives 28 which are arranged at the same angles and are connected in a rotationally fixed manner to a drive shaft 30 via circular disks 29.
  • the cutting edges of the knives are at an angle to the axis and are curved slightly outwards so that they lie within an imaginary cylinder surface.
  • the longitudinal strips are sucked in the direction of the arrows 32 into the area of the knives 28. 3 and 4, the strips are cut into pieces by an axially parallel cutting edge 34 (FIG. 4).
  • Passage openings 36 for the conveying air remain between the knives and the drive shaft 30. Further passage openings for the conveying air exist between those knives 28 that are not currently involved in the cutting process and the inner wall of the tube 26.
  • granulate is formed which is sucked in by the blower 22 through a pipe 40 (FIG. 1), passes through the blower and then via a cyclone 42 for air separation, a climate lock 44 from a further blower 46 through a pipe 48 is finally fed to a press 52 via a collecting container 50. This presses the granules into a press container 54, which is then fed to a disposal point, in particular a waste-to-energy plant.
