Definitions

  • the invention relates to a tube holder for a tube filling machine according to the preamble of claim 1. Furthermore, the invention relates to a tube filling machine with at least one such tube holder.
  • a tube holder for a tube filling machine is known from the WO 2008/064 748 A1
  • a tube filling machine with tube holders is also known from the DE 37 33 687 A1 , from the US 3,199,552 , from the KR 20-0447797 Y1 and from the WO 2012/150 007 A2 ,
  • the flexible clamping sleeve according to the invention allows a uniform force input to a tube jacket, in particular during an entire filling cycle during operation of the tube filling machine.
  • the holding of the tube with the clamping sleeve can be designed by appropriate design of the cuff dimensions so that the clamping sleeve and the tube jacket is neither in any processing phase in the tube filling machine stretched or stretched measurable.
  • a holding force of the clamping sleeve on the tube results due to a different cross-sectional contour of the inner circumference the clamping sleeve to the cross-sectional contour of an outer circumference of the tube end portion.
  • a tensioning collar with an inner cross section round in a force-free state leads to a corresponding holding force, which results solely from the difference in the contour cross sections and the restoring force resulting from a formulaic elasticity of the tensioning collar.
  • the exertion of a holding force can be realized on the tube without holding body attack with corners or edges on the tube and without undesirable deformation of the tube results.
  • the tube holder according to the invention for example, cylindrical aluminum tubes, cylindrical plastic tubes, cylindrical laminate tubes or even such tubes with oval cross section or super oval cross section can be maintained.
  • the clamping sleeve is, as explained above, form-elastic, but not designed elastic. A restoring force does not result from an expansion or compression of the clamping collar in the circumferential direction, but exclusively from the change in shape or the elasticity of the shape.
  • a tube-type tube-filling machine that results across all tubes thus results.
  • the tensioning collar can also compensate for cross-sectional deviations in the region of a tube cover or a tube cap inserted into the tube holding device.
  • an inner circumference of the tension cuff, whether or not the tube end portion is inserted is at least as large as an outer circumference of the tube end portion.
  • metal tubes can be held over a larger axial extent at the tube end portion and thereby supported, without this being an undesirable plastic deformation of the tube jacket leads.
  • a wall thickness of the clamping sleeve can be in the range between 0.1 mm and 5 mm and in particular in the range between 0.25 mm and 1.5 mm.
  • a typical wall thickness of the clamping sleeve is in the range of 1 mm.
  • the clamping sleeve In a full-scale investment of the clamping sleeve on the tube end portion according to claim 2 results in the ability to distribute the holding force over a large area of the tube shell, so that a particularly gentle holding results.
  • the clamping sleeve can rest only on at least one peripheral region or over a plurality of peripheral regions on the outside of the tube end portion.
  • a cross-sectional deviation according to claim 3 results after insertion of the tube into the clamping sleeve due to the flexibility of the clamping sleeve deformation of this, resulting in the form-elastic clamping sleeve to corresponding restoring and thus holding forces exerted by the clamping sleeve on the tube end portion.
  • An inner circumference of the clamping sleeve is always at least as large as an outer circumference of the tube end portion.
  • the tensioning collar can have a multiple rotationally symmetrical cross section, for example a cross section in the form of a spherical square or in the form of a spherical hexagon.
  • the clamping sleeve can alternatively also have a circular cross section. A holding force can result in this case by a deformation of the clamping sleeve from the initially circular cross-section to the predetermined non-rotationally symmetrical cross section of the tube.
  • a holding body according to claim 4 allows a secure holding the clamping sleeve in the tube base holder.
  • the tensioning collar can be braced or clamped radially or axially via the holding body in the tube base holder.
  • This bias of the clamping sleeve for generating the cross-sectional deviation can be generated via a corresponding shape design of the tube base holder or the holding body for holding the clamping sleeve in the tube base holder.
  • the clamping sleeve can thus have, for example, a circular inner cross-sectional shape, which is then deformed by the bias in the tube base holder.
  • the resulting, deformed inner cross-sectional shape of the clamping sleeve then allows the holder of a tube end portion with a circular outer cross-sectional shape.
  • the clamping sleeve can be manufactured according to claim 6 from the house with deviating from the outer cross section of the tube end portion inner cross section. So it can for example a Clamping collar with preformed non-rotationally symmetrical cross section are used.
  • Thermoplastics as clamping sleeve material according to claim 7 have been found to be particularly advantageous in terms of the required material properties for the clamping sleeve.
  • the clamping sleeve can be made of POM, POM-PTFE, PEO or polyolefin.
  • thermoplastic elastomers TPE
  • elastomers even elastomers, in which case only their adhesive properties are used, but not their elasticity in volume, that is to say their extensibility or compressibility in the circumferential direction of the tensioning collar.
  • the material of the clamping sleeve can be a ductile plastic.
  • An insertion of the clamping sleeve according to claim 8 facilitates insertion of the tube into the tube base holder or insertion of the tube into the clamping sleeve.
  • a cover ring according to claim 9 avoids that the tube comes into contact with the other tube base holder during insertion.
  • a total in the Fig. 1 to 5 illustrated tube holder 1 is used to hold a tube 2 in an otherwise not shown tube filling machine.

  • a cover ring 9 An insertion side of the tube base holder 3, ie the side of the base holder 3, from which the tube 2 is inserted into the tube base holder 3, is covered by a cover ring 9.

  • Fig. 1 shows in a plan view of the tube holder 1, of which only the cover ring 9 and an inside of the inner cross section of the cover 9 protruding portion of the clamping sleeve 5 can be seen in this plan.
  • An insertion-side edge 12 of the insertion section 11 of the clamping sleeve 5 abuts the end face of an axial stop surface 13 of the cover ring 9.
  • FIG. 2 shows the holding effect of the clamping sleeve 5 in unclosed tube 2
  • FIG. 4 and 5 the holding effect of the clamping sleeve 5 at the end closed tube 2.
  • a tube sheath closure 14 is carried out at the free end of the tube 2, which is opposite to the tube end portion 4.
  • the tube sheath closure 14 extends in the plane of the Fig. 4 and perpendicular to the plane of the Fig. 5 ,

  • the clamping sleeve 5 is fully outside of the tube 2 and has deformed into a likewise circular cross-section. by virtue of the elasticity of the material of the clamping sleeve 5 causes this cross-sectional deformation due to the insertion of the tube end portion 4 radial forces exerted by the clamping sleeve 5 on the tube end portion 4.
