  • Such film donation facilities are at the need points mentioned installed to allow the user from a roll delivered foil single pieces of different depending on the need Cut off length.
  • the invention is based on known constructions in which the Storage roll of the respective film supply roll a stationary blade or Saw edge is assigned so that the manipulating the leading end Hand after a pivoting movement of the leading end section around the Blade or saw cut off by a pulling impulse can.
  • the known embodiment works with easily tearable and little tough foils regularly in a sufficient manner.
  • tough films such as plastic films the following problem arises: by extreme sharpening of the blade or Saw edge can ensure that even such tough foils sufficient precision can be cut off.
  • the invention has for its object a film dispenser to indicate which enables the cutting of even tough films and reduces the risk of injury.
  • the invention proposes that by manual manipulation of the film advance section, in particular its leading end, a cut off of the respective film leading section triggering relative movement of the cutting edge a guide part can be triggered.
  • the manual manipulation of the film advance section leads according to the invention to an additional cutting movement of the cutting edge compared to the Foil, which supports the cutting of even tough foils.
  • This additional cutting movement by manipulating the film advance section is initiated, it is ensured that the manipulative Person manipulating hands while initiating the cutting process or has fingers at a distance from the moving cutting edge, i.e. outside the danger zone of an injury.
  • the Effective cutting edge without extreme sharpening because you just the additional movement, that is the relative movement compared to the Guide part, is conveyed.
  • the cutting edge can, as long should not be cut, kept in a protective state , for example in a position in which they are shaded by a Protective edge stands and cannot be touched. It then exits this shadow of the protective edge only when cut out should be, i.e. when the manipulation is done, the cutting should initiate.
  • cutting edge should also include saw edges and other edge shapes that cut off enable.
  • the geometry of the cutting edge is not fixed.
  • the cutting edge can run in a straight line, if desired with an inclination with respect to the closest transverse film line. It it is also conceivable to use cutting elements, e.g. Circular knives or circular saws, to be used along a line parallel to the film transverse line Are guided.
  • the relative movement of the cutting edge can be triggered by a tensile force pulse in the pull-off direction on the film.
  • the cutting effect can be supported by the fact that Guide means have a film deflection or kink area, which runs parallel to a film transverse line and that the cutting edge in the Foil deflection or kink area is arranged.
  • the response to the manipulation of the film lead section are still sensitized by the fact that the guidance a Have film deflection or kink area, which is parallel to one Foil transverse line runs and that a tamper-evident sensor system is arranged in the film deflection or kink area.
  • a sensor system that detects the manipulation can, for example, detect one Include film contact body, which by frictional engagement with in Pull-off movement of the film around a transverse film line parallel pivot axis is pivotable. In this case, one is sufficient slight tightening of each with the roll material connected film advance section to the film contact body to cause rotation and thus trigger the cutting movement.
  • the sensors that detect the manipulation can also be used with one of the Apply film in the path that is tailored to the cutting process Pushbutton must be formed.
  • the push button responds if the one caught by manipulating fingers at their leading end Section of the film advance section that has already moved over the cutting edge is approached swinging to the key. The key is then depressed and releases the cutting movement of the cutting edge out.
  • a manipulation-detecting Sensor system a force measuring device assigned to the storage of the film supply roll includes.
  • a force measuring device assigned to the storage of the film supply roll includes.
  • This traction impulse is transferred to the Bearing of the film roll.
  • At this warehouse of the film roll one can Install force sensors that register the occurrence of the tensile force pulse and causes the cutting edge to move relative to it the coordinated route.
  • the film supply roll has an unwinding braking device assigned, although not be excluded is to do that solely by the moment of inertia of the film supply roll a braking effect arises in connection with the respective Manipulation triggers the relative movement causing cutting allowed. If this moment of inertia is not sufficient, then will provide an unwinding brake device which it manipulating hands allowed a tension in the respective film advance section initiate and thereby or in connection with it trigger the cutting process.
  • the cutting edge is arranged substantially parallel to a transverse film line and that the relative movement of the cutting edge relative to the guide part has a movement component orthogonal to the film surface. It should but also can not be excluded that the cutting edge along a film transverse line is displaceable, such as from DE 92 07 836 U known.
  • the guide means can include a storage surface, on which after Cut off a slide advance section the newly created slide advance section is discardable. This will record each made easy on the roll hanging film advance section; this recording can be further facilitated in that the Storage area has at least one depression, which the underside the one still connected to the film supply roll Film advance section for subsequent peeling and manipulation facilitated.
  • the lead agent In order to manipulate the tension of the film on the path length between To concentrate the film supply roll and the deduction-side end of the guide means, it is recommended that the lead agent has a lead agent drainage role comprise which about an axis of rotation parallel to a film transverse line is rotatable.
  • a sensor system that responds to hand manipulation and / or the cutting means are attached to the guide means.
  • the Attachment of the sensors or the cutting means to the guide means can be designed in such a way that the guide means one of the film width define the appropriate route and that on the guidance means on both sides fastening means for the sensor system and / or for outside the guideway the cutting means and / or for a provided at the end of the runway Guide roller are provided.
  • the guide means can be designed as a baffle to be on this Way to create a lightweight construction for a film dispenser is acceptable in terms of construction and costs.
  • the active connection between the cutting means and the sensor system is made as simple as possible for manufacturing reasons, for example in the way that the cutting means as part of a manipulation-responsive Sensor system designed or with such a sensor system by mechanical Transmission means are connected. But it is not meant to be excluded be that an electrical control connection between sensors and Cutting means is used especially when a source of external energy for moving the cutting edge relative to the guide means is provided.
  • a source of external energy can also be used in complex film dispensing facilities dispense with the rotary motion of the roll used when pulling the respective film advance section to to charge an energy store, for example to tension a spring device, which later relaxes when manipulation sensors are operated and thereby causing the relative movement of cutting means and guide means.
  • the film supply roll includes a bearing shaft, which at their ends in a storage pocket of one if desired with several Foil supply rolls stocked roll carrier is stored.
  • the film supply roll attached to a roll carrier which is for hanging on a suspension rail or a Perforated sheet with hook structures and, if necessary, with spacer structures is provided.
  • a film supply roll 10 is rotatably mounted on a shaft 14.
  • the shaft 14 is by bearing pockets not shown on their Ends added.
  • the film is drawn with a dashed line Line 16 shown.
  • the film is at its leading end at 18 between two finger pairs of both hands are grasped and removed up to one Length l of a film lead section, which is for a wrapping or Cleaning process is needed. Then the film advance section l, brought into position 20 without the fingers having to reach around.
  • the Film advance section 1 comes to rest on an eccentric roller 26; the film advance section 1 then becomes a small piece in the direction of the arrow 28 pulled, the eccentric roller 26 rotates in the direction of arrow 30 from the rest position determined by the stop 32 against the Effect of a tension spring 34 up to the stop of the spur 36 on one Stop 38.
  • the gear ratios can be chosen so that the blade 40 with its cutting edge 42 hits the film at high speed and reliably cuts through.
  • Fig. 2 are analog parts with the same reference numerals as in Fig. 1st provided, each increased by the number 100. If the respective film advance section l is reached by pulling off the film the web 120 brought into the dashed line 148. Thereby a pushbutton 150 is pressed down and a knife bar 140 pivots with the result that the cutting edge 142 again in cutting engagement occurs with the slide.

  • the hanging frame 11 is by means of a hook structure 15 hooked onto a carrier rail.
  • the bearing 13 includes 8, a storage pocket 17 into which the two Ends of the shaft 14 can be locked.
  • the storage pocket 17 is attached to a piece of sheet metal 19 which forms a guide surface 22.
  • Fig. 5 - upper half - the film over the guide surface 22 initially essentially horizontally along line 16 deducted until a film advance section of the desired length l is formed. Then the film advance section 1 is into the web 20 (Fig. 5, lower half) tilted so that it has a freely rotatable guide roller 21 runs.
  • the film comes into contact with the eccentric roller 26 so that it is rotated about its axis of rotation 23.
  • 5 are two film dispensers shown one above the other, the upper one in the state of the film being pulled off horizontally along the path 16, while the lower one is in the state of initiating the cutting operation located. If the eccentric roller 26 by the frictional engagement with the Slide from the position of the upper illustration to the position of the lower one Reaches the illustration, the blade 40 reaches with its cutting edge 42 in the cutting position, as shown in the lower half of FIG. 5. The film is cut off and the film advance section 1 can be removed. The newly created film advance section is located then on the guide surface 22 and can be picked up again by fingers and be moved on.

  • Bearing bodies 29 are seated on the shafts 14 for the storage of hollow cores 31 of the film supply rolls.
  • To the Braking film withdrawal from the film supply rolls are the hollow ones Cores 31 of the supply rolls on centering springs 33 of the bearing bodies 29 put on. Through these centering springs 33 an adaptation to hollow cores 31 different diameters.
  • the hollow cores 31 are braked in their rotational movement when the film is pulled off, so that in the film on the way from the respective film supply roll up to the leading end 18 a voltage arises that Triggering the cutting process and the cutting process itself favors.
  • the centering springs 33 can also act so tightly that the desired Braking effect between the bearing tables 17 and the ends the waves 13 is generated. Then of course the bearing body 29 rotating test sitting on the shafts 14. It is also conceivable that the braking effect by mounting the bearing bodies 29 on the shafts 14 is produced.
  • the cutting edge 42 of the blade 40 can be straight or with a serrated tooth be provided. It is also conceivable that the cutting edge 42 across the width of the film web an acute angle with the latter includes, so that the cutting process begins at an edge of the film.
  • the inclination of the blades 40, 140, ... supports the cutting process at least if, in the course of manipulating the film web A trigger movement to trigger the cutting process takes place, even if this deduction movement is only slight.
  • the cutting edge 42 before Initiation of the cutting process practically inaccessible to finger touch is in the shadow of one or more guiding surfaces, e.g. Guide surface 22 in FIG. 5. This eliminates the risk of injury, because the cutting edge 42 only emerges when the Leading end section l for the purpose of triggering the cutting process is manipulated. Then there are the fingers, as in FIG. 1 visible, far outside the cutting edge.
