Definitions

  • the invention relates to a tube holder for a tube filling machine according to the preamble of claim 1.
  • a tube filling machine usually has an endlessly revolving 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 tube with its tube holder is lowered back into the holder.
  • the filled and closed tube is removed from the tube holder and transported away.
  • Tube holders are known in various designs.
  • a tube holder has a housing with an upwardly opening tube holder into which a tube, which is preferably made of plastic or metal, is inserted with its head or cap section.
  • Several clamping elements are arranged in the tube receptacle, which are distributed over the circumference of the tube wall and are each under the action of a spring element.
  • Each clamping element can be adjusted perpendicular to the longitudinal center axis of the tube receptacle and is urged radially inward by the spring element in the direction of the longitudinal center axis of the tube receptacle.
  • the tube presses the clamping elements radially outwards against the respective spring force.
  • the clamping elements are pressed radially from the outside against the outer wall of the tube, whereby the tube is clamped in the tube holder.
  • top and bottom used here relate to the usual alignment of a tube holder with an upward-opening tube holder into which the tube with its head or cap section can be inserted from above, so that the tube with its to be closed The end protrudes from the tube holder at the top.
  • longitudinal center axis of the tube holder extends vertically.
  • axial used here refers to the vertical longitudinal center axis of the tube holder. A radial displacement of the clamping elements takes place perpendicular thereto and thus essentially horizontally.
  • the invention is not limited to a corresponding alignment of the tube holder and / or the tube holder.
  • a tube holder is known in which the clamping elements are each pivotably mounted in a pivot bearing about a horizontally extending pivot axis. In this way, a defined pivoting movement of the clamping elements is given.
  • the tubes are held positively by means of the known tube holder.
  • the tensioning elements are displaced against the spring force, whereby they exert a tensioning force on the tube and thus an increased frictional force.
  • the tube is removed, it is pulled upwards out of the tube holder, whereby the tensioning elements return to their starting position as a result of the spring force.
  • a tube holder is known in which over the circumference of the tube holder alternately upwardly freely cantilevered fingers and downwardly freely cantilevered fingers are arranged, which act radially to internally acting spring elements. Because of the freely protruding fingers, there is no defined pivoting movement for them and, in particular, no defined pivoting axis, so that the clamping elements do not have exactly the same movements.
  • the invention is based on the object of creating a tube holder of the type mentioned, with which tubes of different diameters can be held securely and reliably.
  • a tube holder with the features of claim 1. It is provided that below the 1st group of clamping elements further clamping elements are arranged at an axial distance, which are arranged distributed over the circumference of the tube holder and form a 2nd group of further clamping elements and each with a clamping surface with the outer wall of the tube can be brought into contact and with which, under the action of the spring element and / or at least one further spring element, a clamping force acting radially from the outside on the inserted tube can be applied, the further clamping elements each being pivotably mounted in a pivot bearing about a horizontally extending pivot axis.

  • the clamping surface of the clamping element facing the tube has at least some sections of a convex curvature, the curvature preferably extending from its upper end to the lower end. Because of the convex, curved On the one hand, the contour of the clamping surface facilitates the insertion of the tube and, on the other hand, the pivoting of the clamping element automatically adapts to the diameter of the tube to be picked up.
  • clamping elements are arranged, preferably evenly distributed over the circumference of the tube holder and thus over the circumference of the tube. It has proven to be useful to provide at least two clamping elements and in particular 4, 5 or 6 clamping elements for the tube holder.
  • the several clamping elements should preferably be arranged in the same axial position of the longitudinal center axis of the tube holder, i.e. should not be offset in the direction of the longitudinal center axis of the tube holder.
  • the clamping elements distributed over the circumference of the tube holder form the 1st group of clamping elements.
  • the clamping elements of the 1st group can each be acted upon by their own spring element, in a preferred embodiment of the invention, however, it is provided that all clamping elements of the 1st group of clamping elements are acted upon by a common spring element, for example an annular spring, either directly on the clamping elements engages or indirectly engages the clamping elements with the interposition of at least one component.

  • a separate spring element can be provided for each of the further tensioning elements, but alternatively it is also possible that a common further spring element, in particular in the form of an annular spring, is assigned to all further tensioning elements of the 2nd group of further tensioning elements. However, it can also be provided to assign a single common spring element, in particular in the form of an annular spring, to the 1st group of clamping elements and the 2nd group of further clamping elements.
  • the common spring element can attack directly on the 1st group of clamping elements and its effect is applied indirectly to the 2nd group of further clamping elements, but alternatively it is also possible that the common spring element acts directly on the 2nd group of further clamping elements and that its effect is indirect is applied to the 1st group of clamping elements. Alternatively, it is possible that the common spring element acts neither directly on the 1st group of clamping elements nor directly on the 2nd group of further clamping elements, but on a transmission component from which the spring force acts on the 1st group of clamping elements and the 2nd group of clamping elements Group of further clamping elements is transferred.
  • At least some and preferably all clamping elements and also at least some and preferably all further clamping elements are each pivotably mounted in a pivot bearing with a defined pivot axis. This ensures a defined pivoting movement of the clamping elements or the further clamping elements and thus defined clamping forces on the tube.

In this way, the connecting part with an H-shape connects two clamping elements lying one above the other and is in engagement with the adjacent connecting parts with an H-shape via the horizontal legs.
  • a tube holder 10 has a housing 11, which is preferably made of plastic and has an upwardly opening tube holder 12 in its interior, which resembles a tube T to be received (see FIG Figure 2 ) is adjusted.
  • a longitudinal center axis L of the tube receptacle 12 runs essentially vertically.
  • a 1st group of clamping elements 14 is arranged in the upper region of the tube holder 12, which are distributed over the circumference of the tube holder 12 and are arranged at a common axial height of the longitudinal center axis L. Since the clamping elements 14 are all designed in the same way, only one of the clamping elements 14 is explained below. The same then applies to the other clamping elements 14.
  • the clamping element 14 is mounted in a pivot bearing 20 in the housing 11 so as to be pivotable about a horizontal pivot axis 18. All tensioning elements 14 are pretensioned in the direction of the longitudinal center axis L by means of a common spring element 16, which is formed by an annular spring. The spring element 16 engages the clamping element 14 at a relatively small distance a of approx. 3 mm to 5 mm from the pivot axis 18 (see FIG Figure 2 ).
  • the 1st group of swivel elements 14 there is a similar 2nd group of further swivel elements 14a, which in terms of construction corresponds to the 1st group of swivel elements 14 and comprises several similar swivel elements 14a that extend over the circumference of the tube holder 12 are arranged distributed.
  • the further swivel elements 14a are under the action of a further spring element 16a, which is also designed as an annular spring and acts on the further swivel elements 14a in the direction of the longitudinal center axis L of the tube receptacle 12.
  • Each of the upper clamping elements 14 is connected to one of the lower further clamping elements 14a located axially below it via a connecting part 19, which will be discussed in detail later. All further clamping elements 14a have the same structural design and correspond to the clamping elements 14 in terms of their structural design.
  • the clamping element 14 is block-shaped and around the horizontal Pivot axis 18 can be pivoted, as indicated by the double arrow S.
  • the clamping element 14 is penetrated by the spring element 16 and, on its side facing the longitudinal center axis L of the tube receptacle 12, has a clamping surface 15 which can be brought into contact with an outer wall of the tube T.
  • the clamping surface 15 has a contour that is convex in the direction of the longitudinal center axis L and curved about a horizontal axis.

  • the convex contour of the clamping surface is preferably formed by a section of an involute of a circle in relation to the pivot axis 18, as is symbolically shown in FIG Figure 5 is shown. This has the consequence that for each point of the involute of a circle there is a normal N to a tangent T running through the point at the same distance A from the pivot axis 18 runs. This has the result that the clamping point at which the clamping surface 15 (theoretically, mathematically) comes into contact with the outer surface of the tube T is at the same distance from the pivot axis 18 regardless of the diameter of the tube T.
  • FIG. 6 shows, one of the clamping elements 14 and the associated, further clamping element 14a arranged below are connected to one another via a connecting part 19 and movement-synchronized, that is, when the upper clamping element 14 pivots by an angle ⁇ , this pivoting movement is transmitted via the connecting part 19 to the lower further clamping element 14a transmitted, which pivots through a corresponding angle ⁇ .
  • the connecting part 19 is articulated both on the upper tensioning element 14 and also on the lower further tensioning element 14a, so that, from a kinematic point of view, a four-bar linkage is formed, as is the case on the right-hand side of FIG Figure 6 is shown schematically.
  • the connecting part 19 is in Fig. 7 shown.
  • the connecting part 19 has an H-shaped configuration with two spaced apart vertical legs 19a. Between the upwardly pointing sections of the legs 19a of the connecting part 19 one of the tensioning elements 14 is articulated and between the downwardly pointing sections of the legs 19a one of the lower further tensioning elements 14a is articulated.
  • Each connecting part 19 has a horizontal central leg 19b with horizontal projections protruding on opposite sides, via which adjacent connecting parts 19 are in engagement with one another.
  • One of Projections is designed as a fork (see Fig. 7 , right side), while the projection formed on the opposite side is designed as an engaging part that can be inserted into the fork.
