Abstract

Film store (1) for an endless film (12), with deflection rollers (3, 5), which are fastened to an upper support (2) and to a lower support (4) in such a way that the endless film (12) runs along a between the upper and the lower carrier (2, 4) extending meandering transport path (12a) can be deflected, wherein the distance (13, 16) between the upper and the lower support (2, 4) for resizing the film memory (1) is variable , and wherein the vertical positions (2a, 4a) of the upper carrier (2) and the lower carrier (4) are variable.

Description

  • The invention relates to a film storage for continuous films.
  • In the labeling of containers, for example, beverage bottles, 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. 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. In the known film stores 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. For example, for a roll change in the stock holder, 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. After the roll change is fed faster than conveyed away until the film storage has increased under lowering the lower pulleys back to normal.
  • The disadvantage of such film stores is the limited accessibility of the upper deflection rollers for the manual threading of the endless film through the film storage. Conversely, the height of such film storage is limited due to a required accessibility of the upper pulleys in an undesirable manner.
  • There is thus a need for improved film stores for continuous films in this respect. 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. Under endless film is to be understood here 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. For size adjustment of the film memory, 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.
  • Thus, 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.
  • Preferably, 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. In particular, 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. Such a mechanical coupling is structurally simple and reliable. Under a deflected cable are any combinations of pull / support cables, chains, belts or the like to understand, for example, to guided at least one role and / or run in a shell or rail, for example in the sense of a Bowden cable.
  • Preferably, 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.
  • Preferably, 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. Preferably, the weight is replaceable.
  • Preferably, 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. As a result, the film storage can be adapted to the material properties of the endless film to be stored.
  • Preferably, 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.
  • Preferably, 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 according to the invention 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.
  • Preferably, the film memory according to the invention further comprises a guide means for vertically displacing the lower and the upper carrier. For example, a common guide rail for the lower and the upper carrier may be present. Also conceivable are separate guide rails, as well as guide rods or the like.
  • Preferably, 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.
  • A preferred embodiment of the film storage device according to the invention is shown in the drawing. It shows:
  • 1 the film memory in a position with a minimum memory size;
  • 2 the film memory according to the invention in a position with maximum memory size.
  • As the 1 and 2 can recognize, comprises a preferred embodiment of the film storage device according to the invention 1 an upper carrier 2 with upper pulleys 3 and a lower carrier 4 with lower pulleys 5 , The carriers 2 . 4 are each in the vertical direction along at least one guide device 6 in the vertical direction 6a displaceable.
  • The lower carrier 4 is with a schematically indicated weight 7 complained, so that the lower carrier 4 heavier overall than the upper girder 2 all in all. The upper carrier 2 and the lower carrier 4 are through a cable 8th at the ends 8a . 8b connected with each other. The cable 8th runs over one above the upper beam 2 stored pulley 9 , The cable 8th and the pulley 9 could be functionally replaced by chains, belts and matching wheels. Likewise, several pulleys could 9 and / or Bowden cables or the like for deflecting the cable 8th to be available. Also, mechanical linkage are conceivable in principle, as well as functionally corresponding pneumatic / hydraulic power couplings of the carrier 2 . 4 ,
  • Schematically illustrated are also an input side pulley 10 and an output side pulley 11 so between the upper support 2 and the lower carrier 4 are stored that the upper carrier 2 regardless of its vertical position 2a always above the input side and output side pulleys 10 . 11 located and the lower beam 4 regardless of its vertical position 4a always below it. This ensures reliable guidance of a continuous foil 12 , regardless of the vertical positions 2a . 4a of the upper carrier 2 and the lower carrier 4 , Between the upper and lower pulleys 3 . 5 runs the endless foil 12 along a meandering transport path 12a ,
  • The 1 shows the foil store 1 in a position where the upper beam 2 and the lower carrier 4 to a minimum distance 13 have moved together. For example, monitor / limited by at least one sensor 14 with which the vertical position 2a of the upper carrier 2 can be determined. Conceivable, of course, would be appropriate sensors for the lower carrier 4 , as well as a position limitation by at least one mechanical stop (not shown).
  • At the in 1 shown minimum distance 13 between the carriers 2 . 4 has the foil store 1 its smallest memory size. This preferably corresponds to a placement position 15 of the film storage 1 in which the pulleys 3 . 5 the upper and the lower carrier 2 . 4 are particularly well accessible to operating personnel.
  • 2 shows the film storage according to the invention 1 at maximum distance 16 between the upper carrier 2 and the lower carrier 4 and thus the capacity of the film storage 1 , In normal memory operation, the film memory according to the invention 1 any intermediate position between those in the 1 and 2 occupy positions shown schematically.
  • The management device 6 is in 2 omitted for the sake of clarity. Instead, one is in the 1 for simplicity, not shown transport 18 indicated schematically, the frictional and variable speed on the endless film 12 acts. For example, the means of transport 18 act as a brake by setting the feed rate lower than the removal speed from the film storage device according to the invention 1 , With the help of the tension in the endless foil 12 become the upper carrier 2 and the lower carrier 4 then drove together. Likewise, the means of transport could 18 set the feed speed to a higher value than the discharge speed. In this case, the carriers move 2 . 4 due to their weight difference with the help of gravity apart.
  • Preferably, the carrier can be 2 . 4 in the central assembly position 15 for threading the endless foil 12 lock. Only indicated schematically is a corresponding locking device 19 For example, a mechanical clamp or the like.
  • With the weight difference between the lower carrier 4 and the upper carrier 2 let's put it on the endless foil 12 applied tension within the film memory 1 influence. In the example shown with 1: 1 force coupling is the lower carrier 4 always heavier than the upper carrier 2 to the function in the sense of a dancer even with changing vertical position 2a of the upper carrier 2 to ensure during operation.
  • Especially with a replaceable weight 7 can be flexibly a suitable tensile stress in dependence on the mechanical load capacity of the endless film 12 to adjust. A separate weight 7 However, it is not mandatory if the lower carrier 4 has a total sufficient for the function of the invention weight.
  • It goes without saying that downstream of the illustrated film storage 1 a suitable transport means (not shown) is provided, which is the further transport of the endless film 12 ensures and a suitable tension at the output of the film memory 1 generated.
  • From the prior art well-known devices upstream of the transport 18 for example, to provide, cut and splice the continuous film 12 in a supply roll change are not shown for the sake of simplicity.
  • In general, the film store according to the invention is suitable 1 For any film webs, film tubes or the like and can be, for example, with the help of the weight 7 also to different mechanical requirements when storing endless films 12 to adjust.
  • The carriers 2 . 4 are preferably on a frame 19 of the film storage 1 mounted so that the upper pulleys 3 a predetermined height level 20 to the surrounding soil, especially in the placement position 15 do not exceed, for example, a height level 20 of 2 m, in particular of 1.5 m. This improves the ergonomics when threading the film tube 12 , Conversely, the upper pulleys can be 3 in memory operation according to the invention then arrange on an unavailable for operators without ladders or the like height to a footprint-saving, larger overall height of the film memory 1 to enable.
  • Thus, in particular, allows the movable upper carrier 2 both an ergonomic operation of the film storage 1 as well as to required storage capacities and the respective space adapted designs.
