Definitions

  • the invention relates to a tube holder for a tube filling machine, with a cup-shaped housing which has an upwardly opening tube receptacle into which a tube can be inserted with its one axial end region, a tensioning device being arranged in the region of the tube wall of the tube receptacle, by means of which the Tube a clamping force can be applied.
  • a tube filling machine of conventional construction has an endlessly rotating conveyor device which carries a plurality of receptacles, in each of which a tube holder is inserted.
  • a tube with its head or cap section can be inserted into each tube holder from above, the tube passing through the individual work stations of the tube filling machine together with the tube holder.
  • the filling station and the closing station provision can be made for the tube with its tube holder to be lifted out of the tube holder and inserted into the respective workstation, and after the work step has been completed it is put back into the tube holder is lowered.
  • a removal station the filled and closed tube is removed from the tube holder and transported away.
  • a tube holder of the type mentioned in which at least one tensioning element is arranged in the area of the inner wall of the tube receptacle, which can be displaced essentially perpendicular to the longitudinal central axis of the tube receptacle and by means of which, under the action of at least one spring element, a tensioning force acting radially from the outside on the tube used can be applied.
  • the clamping element is pivotally mounted.
  • top and bottom refer to the usual alignment of a tube holder with an upwardly opening tube holder, in which the tube with its head or cap section can be inserted from above, so that the. Tube with its end to be welded protrudes from the top of the tube holder. With such an orientation of the tube holder, its longitudinal center axis extends vertically and the clamping forces clamping the tube in the tube holder are applied essentially perpendicular to the central longitudinal axis and thus essentially horizontally.
  • the invention has for its object to provide a tube holder of the type mentioned, with which a secure mounting and a good centering of tubes of different formats is guaranteed.
  • the tensioning device has at least one inflatable tensioning element with an inner chamber into which a fluid can be filled under pressure through a feed line, so that the tensioning element can be adjusted between a tensioning position in which a tensioning force is applied to the tube and a release position is. In the release position, there is preferably no tension force or only such a low tension force that the tube can be inserted into and removed from the tube receptacle in a simple manner despite the low tension force.
  • a gas and in particular air is preferably used as the fluid.
  • the invention is based on the basic idea of triggering the adjustment of the tensioning element between the tensioning position and the release position by an externally supplied, pressurized fluid and in particular gas. If the tube holder is empty, ie there is no tube in the tube holder, the clamping element is in its release position. A tube can then be inserted into the tube holder are used and the pressurized fluid is filled into the inner chamber of the clamping element, whereby the clamping element deforms elastically into its clamping position. In this clamping position, the clamping element rests on the outside of the tube and exerts a clamping force on it, so that the tube is held securely in the tube receptacle.
  • the tube holder with the tube inserted can be conveyed through the work stations. If the tube has to be removed from the tube holder or lifted out of it, the excess pressure in the inner chamber is released, whereupon the tensioning element returns to its release position and releases the tube.
  • the tensioning element can be returned to the release position preferably by internal restoring forces due to elastic deformation.
  • a soft-elastic plastic and in particular a thermoplastic elastomer is preferably used as the material for the tensioning element.
  • the tensioning element should preferably have a high elastic deformability, whereby it can be achieved that it can adapt well to the tube shape even in the case of non-round tubes or tubes which have a relatively large deviation from their desired shape and hold the tube with high certainty can.
  • the tube holder usually has a vertically oriented, channel-shaped tube holder.
  • at least one recess is formed which extends radially outward from the tube receptacle and in which the tensioning element is arranged, the tensioning element being affected by the action of the pressurized fluid in the Tube receptacle protruding position and in particular is deformable in the clamping position.
  • the tensioning element is preferably completely retracted into the recess, so that it does not exert any tensioning force on the tube inserted in the tube receptacle. If the tensioning element is deformed by means of the pressurized fluid, the tensioning element is adjusted radially inward into the tube receptacle and is thus tensioned against the tube located there.
  • the recess is designed as a circumferential annular groove.
  • a plurality of clamping elements can preferably be arranged uniformly distributed over the circumference, it is preferably provided that the clamping element is designed in a ring shape and thus its inner chamber is an annular chamber.
  • a plurality of annular chambers can be provided in the tensioning element, which are either acted upon by the same internal pressure from a single pressure source, but alternatively it is also possible to supply a fluid with different pressure to individual annular chambers in order to be able to securely accommodate even highly asymmetrical tubes.
  • the tensioning element preferably fills the recess completely and can be fixed in it positively and / or non-positively, for example by friction or by means of an adhesive.
  • a filling valve and in particular a proportional valve can be arranged.
  • the housing of the tube holder can be placed on a base part in a detachable manner.
  • a coupling device can be provided in the feed line between the housing and the base part, via which the portion of the feed line which is arranged in or on the housing can be connected in a pressure-tight manner to a portion of the feed line which is arranged in or on the base part ,
  • the housing can be placed on the base part and held magnetically thereon, for example. As soon as the housing is correctly placed on the base part, the coupling device is closed and it is possible to introduce the fluid under pressure into the inner chamber of the tensioning element in this position or to drain it out of it.
  • a check valve is arranged in the coupling device, which is automatically opened by placing the housing on the base part, for example by a valve element of the check valve running against a stop and being displaced, as a result of which Check valve is opened.
  • the coupling device is preferably located in the feed line between the filling valve and the inner chamber of the tensioning element, so that the filling valve is not arranged on the housing but rather either on the base part or away from it.
  • the tube holder 10 shown has a cup-shaped housing 11 with an outer, likewise cup-shaped housing base part 11a, into which a housing insert part 11b is inserted.
  • a cylindrical, vertical through-bore is formed in the housing insert part 11b, which forms a tube receptacle 12 and has an inner wall 12a.
  • a circumferential, annular groove-like recess 21 is formed in the inner wall 12a thereof, into which a clamping element 14 made of a soft-elastic, easily deformable material is inserted such that the clamping element 14 completely fills the recess 21 and forms a section of the circumferential boundary of the tube receptacle 12.
  • the clamping element 14 is annular and has an inner chamber 15 in the form of an annular chamber.
  • the clamping element 14 is part of a clamping device 13 with which the tube T can be clamped in the tube receptacle 12.
  • the tensioning device 13 further comprises a feed line 16, which is in the inner chamber 15 of the tensioning element 14 empties.
  • a first coupling part 19 of the feed line 16 is formed in the bottom of the housing 11 and can interact with a second coupling part 20 of the feed line 16, which is formed in a base part 17.
  • the housing 11 can be placed on the base part 17 and is held thereon by clamping, latching or preferably magnetically. When the housing 11 is placed on the base part 17, a fluid-tight connection is provided between the 1st coupling part 19 of the housing 11 and the 2nd coupling part 20 of the base part 17.
  • a fill valve 22, indicated only schematically, is provided in the feed line 16, the coupling device 18 being arranged between the fill valve 22 and the inner chamber 15 of the tensioning element 14.
  • compressed air can be introduced through the supply line 16 into the inner chamber 15 of the tensioning element 14. Since the tensioning element 14 sits with a tight fit in the recess 21 of the housing 11, pressurization of the inner chamber 15 leads to the wall of the tensioning element 14 facing the tube T being deformed radially inwards, ie in the direction of the tube, and against the tube spans like it in Figure 2 is shown.
  • a corresponding projection or pin can be integrated in the second coupling part 20 of the base part 17, which protrusion when the housing 11 is placed on the base part 17 opens the check valve integrated in the first coupling part 19 so that the pressure escapes from the inner chamber 15 of the tensioning element 14 and the tensioning element 14 returns to its release position, as shown in FIG Figure 1 is shown.
