Definitions

  • the invention relates to a film storage for continuous films.
  • the labels are preferably in the form of endless films from a stock holder, such as a film roll, controlled unwound and fed to a film cutter in which individual labels are separated from the continuous film.
  • a stock holder such as a film roll
  • film cutter in which individual labels are separated from the continuous film.
  • film storage Between the stock holder and the film cutter are known to use film storage, as used for example in the DE 3727339A1 and the EP 2284108A2 are described.
  • the endless film is guided back and forth in such film stores along a meandering transport path between an upper and a lower group of deflection rollers, wherein the storage size of the film storage device depends on the distance between the upper and lower deflection rollers.
  • the upper deflection rollers are firmly mounted.
  • the lower pulleys can be mounted on a support, move along a vertical rail or the like. Here, the weight of the lower rollers and their support is carried by the current through the film storage endless film under appropriate tension.
  • Such film stores buffer variations of the transport speed upstream and downstream according to the principle of a dancer by the distance between the upper and the lower group of transport rollers and thus the length of the continuous film running in the film storage dynamically changes.
  • the feed with an input side brake or the like is stopped in continuous conveyance of the endless film, so that the lower pulleys are pulled continuously by the still remaining in the film storage endless film.
  • the roll change is fed faster than conveyed away until the film storage has increased under lowering the lower pulleys back to normal.
  • the stated object is achieved with a film store according to claim 1. Accordingly, this is designed for continuous films, such as film tubes for labeling containers, in particular beverage bottles, with label sleeves.
  • endless film is here too Understand that the film in the sense of a film web or a film tube during production constantly running through the film memory.
  • the film storage device comprises deflection rollers which are fastened to an upper support and to a lower support in such a way that the endless film can be deflected in the storage operation along a meandering transport path extending between the upper and the lower support.
  • the distance between the upper and the lower carrier is variable. According to the invention, not only the vertical position of the lower beam but also the vertical position of the upper beam is changeable.
  • the upper carrier for threading through the endless foil and / or for maintenance measures can be lowered into an ergonomic position. Accordingly, the upper support for the normal memory operation can be arranged in a higher position than is still acceptable with firmly mounted upper straps from an ergonomic point of view.
  • the upper and lower beams are mechanically, pneumatically and / or hydraulically coupled to each other such that lowering of the lower beam causes lifting of the upper beam and vice versa.
  • the lower and the upper carrier can then be lowered and lifted in opposite directions as a function of a weight difference between the two carriers and the counteracting tensile stress in the endless foil. This allows ergonomic operation of the film memory, in particular a change between a position when loading the film storage and a position in the normal storage operation.
  • a mechanical force coupling is conceivable, for example, by connecting the upper and the lower carrier by means of a cable, chain, linkage or the like.
  • a pneumatic and / or hydraulic power coupling is conceivable by means of coupled lifting cylinders, lines, fluids and the like.
  • a particularly favorable embodiment of the film storage device according to the invention comprises a cable, which is deflected above the upper support and whose one end is connected to the upper support and the other end is connected to the lower support.
  • a mechanical coupling is structurally simple and reliable.
  • a deflected cable is to be understood as meaning any combination of tension / suspension cables, chains, belts or the like which, for example, run around at least one roller and / or run in a casing or rail, for example in the sense of a Bowden cable.
  • the lower carrier is heavier than the upper carrier. This allows the principle of a dancer in a one-to-one power coupling between the upper and the lower carrier, so in each case inversely corresponding strokes of the upper and lower carrier.
  • the lower beam includes a weight for adjusting a weight difference between the lower and upper beams. This allows a defined weight difference between the lower and the upper carrier set.
  • the weight is replaceable.
  • a tensile stress acting on the endless foil during storage operation is adjustable by predetermining a weight difference between the lower and the upper support.
  • the film storage can be adapted to the material properties of the endless film to be stored.
  • the upper carrier and the lower carrier in particular together, can move together in a central position for loading the film storage.
  • This allows a particularly ergonomic assembly, in particular the threading through the endless film.
  • the upper carrier and the lower carrier can be locked in the central position. This facilitates the loading of the film storage with endless film.
  • a particularly favorable embodiment of the film storage device further comprises input-side and output-side deflection rollers which are fastened in such a way that they are located in the central position of the carriers below the deflection rollers of the upper carrier and above the deflection rollers of the lower carrier. This ensures a reliable deflection of the endless film both when threading the endless film as well as in normal storage operation.
  • the film memory according to the invention further comprises a guide means for vertically displacing the lower and the upper carrier.

  • the deflection rollers of the upper carrier in its lowest position not exceed a height level of 2 m, in particular of 1.5 m. This ensures an ergonomic position of the upper carrier when threading the endless foil for the respective operating personnel.
  • the film storage comprises roller-shaped deflection rollers with a length which is greater than its diameter. This allows reliable operation even in the event that changes the track or lateral position of the endless film on the pulleys during operation of the film storage.
  • the deflection rollers may be cylindrical.
  • the deflection rollers may have a smooth lateral surface.
  • the film storage device comprises a tracking control unit formed downstream, in particular downstream of the output-side deflection roller. This allows an output side correction if the track or lateral position of the endless film on the pulleys during operation of the film storage changes.
  • the film storage device comprises a film drive unit, which is formed downstream, in particular downstream of the output-side deflection roller, for further transporting the endless film.
  • a film drive unit which is formed downstream, in particular downstream of the output-side deflection roller, for further transporting the endless film.
