Definitions

  • the invention relates to a film transport device for transporting a stretchable film with at least one belt conveyor, the belt conveyor having two opposite transport belts for transporting the film and a first and a second deflecting roller, each of which endlessly guide one of the transport belts and arranged at the end in the respective transport belt are.
  • a packaging machine for packaging packaging goods by means of films is known.
  • the films are conveyed from a film dispenser through a movable film guide element to a film transport device.
  • the film transport device has two synchronously operated belt conveyors arranged in parallel.
  • the films are transferred from the film dispenser to the belt conveyors of the film transport device.
  • the conveyor belts take up the film by friction.
  • the film is transported by the belt conveyors to a position in the packaging machine in which a packaged product can be brought up to the film and packaged in the film.
  • the known film transport device has two deflection rollers over which the belts run.
  • the pulleys and belts are flush.
  • the belt thus protrudes beyond the deflection roller in the radial direction.
  • the film is placed between the two belts by moving the slide and the guide plate accordingly.
  • the belts take up the film due to a frictional connection. This film transfer can cause problems with variable film thickness and / or quality, which is why the arrangement is normally only ever set for a specific film thickness / quality.
  • the object of the invention is to provide a film transport device for a packaging machine of the type defined in the introduction, in which the introduction of the film into the film transport device is process-reliable and to a greater extent independent of the thickness and quality of the film, even without changes to the film transfer device.
  • a generic packaging machine which is characterized in that the first deflecting roller projects with one end section beyond the transport belt assigned to it, and that the first deflecting roller has a first transport ring at its end section along its circumference that the second deflection roller projects with an end section beyond the transport belt assigned to it, and that the second deflection roller has a second transport ring along its circumference at the end section, a first contact surface of the first transport ring with mechanical friction extending along the circumference of the first deflection roll, wherein a second contact surface of the second transport ring with mechanical friction extends along the circumference of the second deflection roller, and wherein the contact surfaces abut one another with frictional engagement.
  • the films are introduced between the transport rings when they are fed to the film transport device and come into contact with the transport rings with static friction.
  • the transport rings can continue to transport the foils until they are taken over by the transport belts. This increases the stability of the process of introducing the film into the film transport device.
  • the pulleys are designed so that they have a protruding area on the side of the conveyor belt, which is made of an elastic material, for. B. rubber is formed.
  • the two deflection rollers thus form their own frictional connection, which conveys the film a little further until it is reliably taken over by the belts.
  • the rubber rings of a pair of rollers are arranged so that they deform each other slightly at the point of contact, which creates a frictional connection.
  • An advantageous embodiment of the film transport device is characterized in that the transport rings consist of elastically deformable material, in particular of rubber-elastic material. By pressing the elastic materials of the transport rings together, the frictional engagement can be achieved in a space-saving manner.
  • a preferred development of this embodiment is characterized in that the transport rings in their frictionally abutting state on the contact surfaces have a flattening inwards in the radial direction in comparison to the rest of the surface of the transport rings.
  • the surfaces of the contact surfaces are pressed by the respective other contact surface in the direction of the deflection roller belonging to the respective contact surface.
  • the contact surface is flat and the distance between the contact surface and the longitudinal axis of the deflection roller is smaller than the distance between the remaining surface of the transport ring and the longitudinal axis of the deflection roller.
  • a further embodiment of the film transport device is characterized in that at least one end section of the first deflecting roller and / or the second deflecting roller as a transport ring is trained. If the entire end section is designed as a transport ring, a frictional engagement with the film can be brought about on a particularly large area.
  • a further advantageous embodiment of the invention is characterized in that at least the end section of the first deflection roller and / or the second deflection roller has a plurality of transport rings of the end section, in particular two transport rings of the end section.
  • the use of several transport rings is one way of increasing the area of the frictional connection.
  • the transport rings are made of the same material. If the transport rings are made of the same material, a flat surface of the contact surfaces can be brought about when the transport rings are pressed against one another, thus preventing the foils from bending.
  • a further advantageous embodiment of the film transport device is characterized in that the first deflecting roller with a further end section, which lies opposite the end section of the first deflecting roller, projects beyond the transport belt arranged on it.
  • the first deflection roller has a third transport ring along the circumference of the first deflection roller.
  • the second deflection roller projects with a further end section, which lies opposite the end section of the second deflection roller, beyond the transport belt arranged on it.
  • the second deflection roller has a fourth transport ring along the circumference of the second deflection roller.
  • the third and fourth are in particular Flat transport ring against each other under frictional engagement. Transport rings with contact surfaces are provided on both sides of each deflection roller. As a result, frictional connections for the film are produced on both sides of the deflection rollers in order to increase the safety of the process of film insertion into the film transport device.
  • At least one deflection roller has a gearwheel for driving by means of a gearwheel gear, wherein a washer can be arranged in particular between the transport ring of the deflection roller and the gearwheel.
  • the deflection roller can be driven in a particularly simple manner by such a gearwheel.
  • Another embodiment of the invention provides that the transport rings are fastened to the associated deflection rollers by means of bolts and / or screws. As a result, the transport rings can be attached to the associated deflection rollers in a simple manner.
  • a preferred embodiment is characterized in that the deflection rollers each have a layer-like structure.
  • a first layer comprises a gearwheel with a ball bearing.
  • a second layer comprises a first washer, which is arranged on the gear.
  • a third layer comprises a transport ring, in particular a rubber ring, which is arranged on the first washer.
  • a fourth layer comprises a second washer, which is arranged on the transport ring.
  • the layers are firmly connected to one another by means of screws. The transport rings are protected and cushioned from the other components of the deflection roller by the washers.
  • the screws are designed as screw bolts with a thread-free section. Screw bolts are particularly easy to insert into the associated openings.
  • a further improvement of this development can be achieved in that the layer structure has through holes for pushing through the screw bolts, which are fastened on the other side by lock nuts. This means that all layers can be attached to each other.
  • a packaging machine for packaging packaging goods by means of a stretchable film which has a film transport device according to the invention, also falls within the scope of the present invention.
  • Such a packaging machine modified according to the invention is distinguished by a high degree of process reliability when a film is introduced into the film transport device.
  • Fig. 1 shows an isometric front view of a packaging machine 10 for packaging packaging goods (not shown) by means of a stretchable film (not shown).

  • the choice between the second, third or fourth recess 21b-21d is made in such a way that the distance 23 of the belt conveying devices 12a, 12b in the recesses 21a-21d corresponds to the width of the film. This defines the zero positions of the belt conveyors with respect to the width of the film. If the second recess 21b surrounds the second belt conveyor 12b, this is referred to as "first zero position" in the context of the application. If the third recess 21c engages around the second belt conveyor 12b, this is referred to as "second zero position" in the context of the application.
