Definitions

  • the invention relates to a device for temporarily holding and holding open preferably elastic containers on a filler neck, which is surrounded in its lower region by several spreading segments which protrude beyond its lower edge and are encompassed by a spring element and which extend in the direction of the flow of material Filler neck can be spread from this with uniform pivoting around a support line running around the neck and thereby cause the containers to be fixed.
  • DE-OS 1461795 shows a device which is improved in terms of the sealing effect but is inadequate in the holding function - at least for containers to be filled from above - in the form of an expandable leadpipe.
  • a filling pipe for valve bags arranged in a horizontal position over a considerable part of its length surrounded by one or two half-shells, which in turn are surrounded by a rubber sleeve and thus rest against the filling tube in their rest position.
  • An elaborate spreading mechanism grips these half-shells at their ends facing away from the outlet opening of the filling tube, so that the rubber sleeve for filling the sacks is widened at their rear ends and seals against the sack opening.
  • the holding of the bags is only guaranteed to a limited extent.
  • Another device known from DE-OS2231 040 for filling dimensionally stable or shape-changing containers from above works with a holding device which consists of four rounded sector pieces arranged around a cylindrical material outlet nozzle, which are held together in their upper regions by an annular spring.
  • the spring and with it the holding device In the rest position, the spring and with it the holding device is located at the lower end of the outlet nozzle and pulls the sector pieces together in the sense of a funnel formation.
  • the holding device together with the spring on the material outlet nozzle is shifted upwards, cams stamped into the sector pieces, in cooperation with an inclined surface on the outlet nozzle, causing the sector pieces to spread apart from the nozzle, which of the Spring is supported.
  • the object of the invention is to combine the advantages of systems working with mechanical expansion elements, such as in particular long clamping paths defined by a fixed end stop, with the essential advantage of better sealing of the systems working with inflatable elements.
  • this combination should be simple, light and compact, so that the device according to the invention is particularly suitable for use on portable dosing weighing devices with minimal weight and space requirements.
  • the spring element consists in a known manner from a sleeve made of elastic material that spans the spreading segments designed as 4 angle levers in their entirety, the spreading segments in the axial direction of the filler neck compared to one of the sem attached, circumferential contact surface are pivotally locked in the area of their bend and the common spreading takes place under the action of force on the outwardly angled actuating arms of the expansion segments.
  • the bearing points for the expansion segments are thus virtually formed by simply placing the expansion segments between the filler neck and the contact surface or the collar, the collar simultaneously taking over their fixing.
  • the expansion segments are of flat design perpendicular to their spreading planes, and their number is such that they are at a round filler neck in its entirety in the non-activated state form an approximately round outlet opening in a manner known per se.
  • the containers which are held open and made available by a separate device in an annular manner, are by no means missed by the outlet opening, or that they always reach the containers with certainty
  • the spreading segments have a taper compared to that lower edge of the filler neck in the direction of its longitudinal axis angled ends.
  • the spreading segments are guided by a collar that is guided on the filler neck and that embodies the fixed surface of the contact surface up and down movable cam ring actuated, the actuating arm of each expansion segment pointing obliquely downwards from the wall of the filler neck and cooperating with the cam ring.
  • the range of movement of the expansion segments can be determined in an incredibly simple manner by the degree of the inclined arrangement of their actuating arms.
  • the lower area of the cam ring is covered by an enlarged collar of the collar in a further advanced embodiment of the invention.
  • an advantageous development of the invention provides for an inflatable pressure hose for the movement of the cam ring.
  • the cuff expediently also performs an important function for reliably holding the containers in place by providing a friction-increasing profile on its outer surface.
  • the holding device shown in the figures is arranged on a hollow cylindrical filler neck 1, which is provided with an opening 2 for the material to be filled and a flange 3 for fastening z. B. on a spout, a weighing device or the like.
  • the holding device itself essentially consists of a multiplicity of spreading segments 4, a cuff 5 of elastic material that surrounds this and a lifting ring 6 with an inflatable pressure hose 7.
  • the spreading segments 4 which are designed to simplify production as flat-surface angle levers, are arranged in a large number, which brings about an approximation to the cylindrical shape of the filler neck 1 (see FIG. 3), in a uniform distribution around the lower region of the filler neck 1 and on this through the Tension of the cuff 5 held.
  • the spreading segments 4 protrude with their ends 4a angled in the direction of the longitudinal axis of the filler neck 1 over the lower edge 1a of the filler neck and thus form a taper in the direction of the crop flow, so that the introduction into a container provided in an open form (not shown) made easier.
  • each expansion segment 4 has an actuating arm 4b which is angled downwards, and in the region of this angling, all expansion segments 4 lie against a circumferential collar which is fastened to the filler neck 1 and which fixes the expansion segments 4 upwards.
  • This collar 8 simultaneously forms the support for the cam ring 6, which is designed as a circumferential box profile, in that the latter is supported on the collar 8 by means of its inner support ring 6c and via a cam ring cover 9.
  • the cam ring 6 also encompasses the inflatable pressure hose 7 and the actuating arms 4b of the expansion segments 4.
  • a collar surface 8a serves as a support plane for the pressure hose 7 which is in contact with the cam ring cover 9 in its upper region, and a collar edge 8b forms a stop for the angled ends 4a of the expansion segments 4, the lifting ring base 6a only linear in their rest position touch.
  • the cam ring base 6a is provided with a circumferential opening 6b for the passage of a curvature of the sleeve 5, which by means of a collar 5a encompasses the entire lower region of the cam ring 6 for sealing against leakage.
  • a somewhat lower requirement for such a sealing sufficient design could be equipped with a less complex sleeve, which only grips the expansion segments up to the end of their area adjacent to the filler neck and ends in front of the angled actuating arms.
  • the mode of operation of the holding device starting from the rest position shown in FIG. 1, is as follows:
