Definitions

  • the invention is therefore based on the object of a device for compressing small liquid containers, in particular incorrectly filled beer cans or the like. To create upsetting that allows the small containers to be compressed in a time-saving and labor-saving manner and thereby to be separated from the liquid in them in a hygienically correct manner, so that the separate reuse of these components is possible.
  • the device for upsetting has an essentially horizontal stuffer box provided with an upper feed hopper and with a liquid collecting trough arranged below its liquid-permeable bottom, at one end of which a side chamber corresponding to its profile with a housed therein, hydraulically operated in the stowage chamber laterally in and out of it Press ram and at the other end opposite the latter there is an ejector tube which is curved in order to form a sufficient pressing resistance and which narrows increasingly towards the tube end.
  • Advantageous is curved o the ejector tube relative to the tubular outlet end of the stuffer box by less than 50th
  • the ejector tube is advantageously provided with longitudinal slots which open out freely to the tube end, the tube segments which are thereby separated from one another being able to be connected to one another via prestressable suspension elements which cross the longitudinal slots.
  • the conicity of the ejector tube can be adjusted to a certain extent via the corresponding pretensioning of the suspension elements, and thus the compression resistance in the ejector tube which is adapted to the respective upsetting material can also be set.
  • a corresponding pressing resistance must be provided in the ejector tube. In principle, this can be achieved by upset material remaining in it from the preceding upsetting presses, which adheres in the ejector tube with sufficient frictional resistance.
  • the respective retention of upsetting material in the ejector tube after the respective upsetting press work is disadvantageous insofar as it necessarily leads to soiling in the interior of the device.
  • filler plugs can be introduced into the ejector tube, most of which have a smaller outer diameter compared to the inner diameter of the ejector tube end, but one or more of these filler plugs have a larger one, namely or essentially corresponding to the inner diameter of the ejector tube end have a little larger outside diameter.
  • Such fill plugs can be pressed into the ejector tube in a suitable number and sequence via the feed hopper and the stuffer box with the aid of the press ram.
  • the ejector tube can be fitted with a built-in locking slide and / or one that is placed on the end of the tube Area cap must be partitioned.
  • the ejector tube can also consist of two conical longitudinal tube halves which are connected to one another in a hinged manner.
  • a hydraulic lifting cylinder with a piston rod displaceably guided therein is provided for the actual pressing device in the side chamber, axially central, at the inner end of which a piston which can be acted upon from both sides and at the outer end of which the pressing cylinder enclosing the lifting cylinder over its almost full longitudinal extent its end wall facing the stuffer box is fastened.
  • the device shown in Figure 1 is particularly for the upsetting of incorrectly filled beer cans or the like. Upset determined. It has a substantially horizontal tubular cylindrical stuffer box 2, which is inclined only a few degrees with respect to the installation surface 1 and which is provided with an upper feed hopper 3 of sufficient width for the goods to be squeezed to be fed in here, in particular thus incorrectly filled beer cans. At one end of the stuffer box 2 there is in its extension a side chamber 4 corresponding to its profile with a hydraulically operated press ram 5 which is accommodated therein and can be moved laterally into and out of the stuffer box 2.
  • the press ram 5 is fastened with its end wall 5 'facing the compression chamber 2' to the free end of a piston rod 6 which is displaceably guided in the hydraulic lifting cylinder 7 arranged axially centrally in the side chamber 4.
  • a double-acting piston 8 is provided, which is sealingly guided in the lifting cylinder 7.
  • the hydraulic medium in particular a suitable oil, can optionally be supplied to the lifting cylinder 7 at one end and discharged from it at the other end via the hydraulic lines 11, 12 from a hydraulic device not shown, so that the piston rod 6 and with her the ram 5 can be operated accordingly reversing.
  • the ejector tube 14 which is provided with a bend section 13 and which narrows conically towards its outlet end 14 ′, is connected to the stuffer box 2.
  • the curvature of the ejector tube 14 relative to the stuffer box tube 2 is less than 50 ° , which has proven to be sufficient in any case for the compression molding of beer cans.
  • This pipe bend is advantageously in the range of 45 ° .
  • the ejector tube 14 is provided on both sides with longitudinal slots 15 which open out freely to the tube end 14 '.
  • the pipe segments 14 ′′ which are separated from one another in this way are connected to one another by prestressable suspension elements 16 which cross the longitudinal slots 15. On in this way, the pipe segments 14 ′′ can be adjusted accordingly with regard to their compression resistance pressure exerted on the upsetting material passing through them, and at the same time they can also be elastically spread to a certain extent.
  • the bottom 2 'of the stuffer box 2 is provided with liquid passage slots 2' '. Below them is a liquid sump 17, which rests on the bearing points 18 of the device frame.
  • This frame can optionally also, as shown in FIG. 2, be provided with fixed or swivel castors 19 in order to make the pressing device movable.
  • the fill plugs 20 ', 20''indicated by dash-dotted lines in FIG. 1 can be used for this.
  • These fill plugs are advantageously made of a hard-elastic material, in particular corresponding plastic, so that they can adapt to the passage of the ejector tube 14 by slightly elastic deformation of the pipe curvature, but at the same time are sufficiently pressure-resistant for the generation of the compression resistance pressure.
  • the fill plugs 20 have different outside diameters.
  • the outer diameter is smaller than the inner diameter of the ejector tube end 14', so that these fill plugs 20 'can slide freely in the ejector tube 14.
  • at least one of these filler plugs 20 ′′ has a larger outer diameter, namely one that essentially corresponds to the inner diameter of the ejector tube end 14 ′ or is even slightly larger, so that this filler plug 20 ′′ is seated in the ejector tube 14 with a corresponding static friction resistance.
  • the compression molding work can be started by feeding the beer cans to be compressed via the feed hopper 3 and by switching on the hydraulic device by the press plunger 5 which works with a few strokes per minute and which reverses Stuffer box 2 are pressed against the initial resistance pressure of the filler plugs 20 ', 20''.
  • the from the Filling liquid escaping to be compressed passes through the bottom slots 2 ′′ into the collecting trough 17, from which it can be discharged via the outlet 17 ′ and a drain line to be connected to it.
  • the filling plugs 20 ', 20'' are increasingly pushed out of the ejector tube 14 by the pressing compression material until finally only compressed compression material fills the tube 14 or leaves it.
  • the upsetting device can be cleaned every evening after the pressing work has taken place, its ejector tube 14 must be able to be freed from the upsetting material that is still therein.
  • the filling plugs 20 ', 20' ' are again used for this purpose, in the manner already described above.
  • an annular seal 21 is provided in the housing wall 4 'of the side chamber in the vicinity of the stuffer box 2, which is constantly applied to the circumference of the press ram 5. Nevertheless, the side chamber 4 or its interior must be cleaned for hygiene reasons.
  • detergent connection points 22 are provided in the side chamber housing wall 4 'for the supply and discharge of a corresponding detergent.
  • the ejector tube 14 shown in FIG. 2 differs from that shown in FIG. 1 essentially only in that it has a locking slide 23, which is preferably installed directly behind the tube bend 13 and with which the ejector tube 14 can be sealed off, as at the beginning of the respective upsetting press for the initial pressing resistance generation required for this.
  • Such gate valves 23 can also be provided at other points of the ejector tube 14 for its partial partitioning.
  • the ejector tube 14 can also consist of two conical longitudinal tube halves 14 ′′ ′′, 14 IV , which can be hingedly connected to one another via the joints 25, one of which, in particular the lower longitudinal tube half 14 IV , with the stuffer box housing 2 '''can be firmly connected via the ejector elbow 13'.
  • the two longitudinal tube halves 14 IV can be kept closed by the locking latch 26. This also makes particularly simple cleaning of the ejector tube 14 possible simply by opening the upper tube half 14 '''.
  • the device according to the invention can also be used for upsetting other small liquid containers, such as e.g. of juices or the like Drinking liquids filled sheet metal or cardboard packs with the same advantage as can be used in the compression molding of beer cans. Also with other liquids, e.g. Cleaning liquids incorrectly filled small containers can be squeezed with the new device without labor and time saving.
  • other small liquid containers such as e.g. of juices or the like Drinking liquids filled sheet metal or cardboard packs with the same advantage as can be used in the compression molding of beer cans.
  • other liquids e.g. Cleaning liquids incorrectly filled small containers can be squeezed with the new device without labor and time saving.
