Definitions

  • the invention relates to a rewinder for winding film residues for packaging machines according to the preamble of claim 1.
  • a winding device of a thermoforming packaging machine for winding up waste strips such as edge strips and center strips goes out of the DE 1922848 out.
  • the winding device has a shaft driven by a cutter on which rest one or more tubular winding body with its inner diameter.
  • a cutter on which rest one or more tubular winding body with its inner diameter.
  • a disadvantage is the undefined, significantly changing during winding slip, and that the winding body must be disposed of together with the wound waste strips.
  • Thermoforming packaging machines are also known, which in each case have an edge strip winder on both sides in a region in which a foil feed releases a foil web to be transported.
  • Each RandstMailwickler is driven with its own motor and turned on for a certain period for winding.
  • tray sealing machines are known which wrap a residual foil grid of the lid foil by means of a rewinder.
  • From the EP 1 655 258 A2 is a friction element for transmitting a certain torque to a winding core for winding tape-shaped materials such as adhesive tape known.
  • the EP 0 437 751 A2 discloses a winding shaft for simultaneously winding a plurality of web strips side by side with the same web tension with an adjustable torque.
  • the JP 60 204552 A discloses a winding shaft for sheet material with a very high winding force.
  • a winding device which provides two torque adjustment discs, both of which have a plurality of permanent magnets and which are mutually adjustable in distance and thus the torque is variable.
  • the object of the present invention is to improve a rewinder for a packaging machine with regard to its use for winding waste strips and / or residual foil lattices.
  • the rewinder according to the invention for winding film residues for packaging machines comprises a drive, a mandrel and at least two winding rollers and has an adjustment for adjusting a torque threshold, above which a slip between the individual winding rollers and the winding mandrel and / or between the Winding rollers occurs to each other.
  • the adjusting device comprises coupling elements via which the mandrel transmits a torque to the winding rollers, and provides a machine operator according to the invention the ability to increase or decrease the torque threshold.
  • the advantage here is, on the one hand, that a common drive is provided for several winding rollers, which transmits its torque to the winding mandrel and the winding mandrel transmits the torque to the winding rollers via coupling elements. Above the set torque limit, slip may occur on the winding rollers independently of each other.
  • the torque limit limits the maximum tensile force acting on a waste strip or a residual foil grid. When the drive is running and the feed of the packaging machine is stationary, the waste strips or the residual foil grid can no longer be wound up and the winding rollers can stop, even at different times, since the torque threshold is exceeded and the desired slip occurs without having to shut down the drive at this moment.
  • the winding rollers can also rotate differently during winding. The adjustment of the torque threshold and thus the tensile force on the waste strip or the residual foil grid allows an adaptation to the material properties of the waste strip or the residual foil grid and leads to an improved process reliability during winding.
  • the adjusting device further comprises at least two cooperating permanent magnets.
  • Such a magnetic coupling works wear-free even when running in continuous operation drive.
  • Another advantage is that permanent magnets do not need to be powered.
  • the permanent magnets according to the invention in the axial direction of the winding mandrel relative to each other adjustable to adjust the torque threshold of the winding rollers to the winding mandrel.
  • the adjustment device has a plurality of coupling rings, which are arranged laterally and / or between the winding rollers. This allows a simple and inexpensive construction.
  • the coupling rings are preferably made of the approved in the food industry material POM (polyoxymethylene).
  • a dial for axially compressing the coupling rings and the winding rollers is provided on the winding mandrel to adjust the slippage continuously and in a simple manner by the operator of the packaging machine can.
  • the setting wheel is attached to an end of the winding mandrel opposite the drive, since it is then located on the operating side of the packaging machine and is thus very easily accessible.
  • a spring element is provided on the winding mandrel between the drive and the winding rollers, wherein the adjusting wheel is movable against the spring element to increase the torque threshold.
  • the winding rollers preferably have a plurality of roller elements, which can be spread radially to the winding mandrel by laterally mounted and axially displaceable clamping elements.
  • the roller elements can be adjusted to a maximum outer diameter of the winding roller and, after winding, to slightly pull down film residues, the roller elements are reduced to a smaller outer diameter.
  • clamping element which is furthest away from the drive can be removed from the winding mandrel in order to be able to axially remove a rolled-up film residue from the device.

  • an insertion path 15 is provided, in which the containers 14 formed in the first web-shaped material 8 are filled with product 16.
  • the sealing station 3 has a closable chamber 17 in which the atmosphere in the container 14 can be replaced prior to sealing, for example, by gas purging with a replacement gas or with an exchange gas mixture.
  • the cross-cutting device 4 is designed as a punch that cuts through the first web-shaped material 8 and the second web-shaped material 10 in a direction transverse to the working direction R between adjacent containers 14.
  • the cross-cutting device 4 operates such that the first web-shaped material 8 is not divided over the entire width, but at least in an edge region is not severed. This allows a controlled onward transport by the feed device.

  • the drive 24, for example, a servo motor transmits its torque to the mandrel 29 and the rotatably mounted on the winding mandrel 29 clamping elements 27.
  • the torque is further transmitted to the winding rollers 25a, 25b.
  • the dial 28 is screwed onto the winding mandrel 29 and presses the outer Mit videbuchse 31 via the outer coupling ring 30 on the outer clamping element 27 and in consequence on the roller elements 32a of the outer winding roller 25a and the further clamping element 27.
