Definitions

  • the invention relates to a device suitable for the metered filling of flowable or pasty filling material into containers, which consists of a housing provided with an inlet and outlet opening for the filling material, preferably arranged horizontally, a rotatably mounted in the housing and the inlet and outlet opening alternately releasing and closing, at least partially conical rotary cylinder, which has at least one window-like passage opening in its wall and is mounted in a bearing part, and also with an essentially coaxial to the axis of rotation of the rotary cylinder and on the inner wall of which is displaceably guided between a suction position and an ejection position, one in a bearing part slidably guided piston rod having a metering piston, through its outer surface in the initial position of the suction stroke and in the end position of the exhaust stroke at least a third of the window-like passage opening of the rotary cylinder and the substantially same size as the passage opening formed inlet opening is covered, which is the same as the passage opening cross-section at least approximately equal to the cross sectional
  • the metering piston of the known device is formed by a piston head acting as a displacer and a piston sleeve.
  • the piston head is bevelled on its rear side towards the piston sleeve.
  • the invention has for its object to provide a suitable device for the metered filling of flowable or pasty contents into containers of the type mentioned, which with a compact or compact Construction and simple manufacture and assembly at the same time ensure gentle handling of the filling material and enable good flushing of the device on all sides by means of a cleaning liquid.
  • the means according to the invention arrives at a metering device that solves the task in an optimal manner.
  • the arrangement of the end face of the metering piston in the region of the edges of the passage opening and the inlet opening in the end position of the suction stroke or the starting position of the metering piston for the ejection stroke ensures that the product is not deflected, so that it is subjected to a gentle treatment.
  • the device is therefore particularly suitable for salad-like or dry and low-fat products. Since the metering piston is also supported on the inner wall of the rotary cylinder, at least over part of its length, in the end position for the ejection stroke or in the initial position of the suction stroke, the metering piston is guided precisely at all times and thus the product quantity is metered precisely .
  • the metering piston acts both as a guide and as a sealing element, so that special sealing elements such as piston sleeves or the like can be dispensed with.
  • the arrangement of the bearing parts for the journal of the rotary cylinder and the piston rod of the metering piston on opposite sides of the device leads to favorable space conditions, which ensure simple manufacture and assembly.
  • good rinsing is also ensured, since such a device enables the two interacting components, namely the rotary cylinder and the metering piston, to be pulled apart in opposite directions in the cleaning position so that they no longer have any contact with one another.
  • comparatively large channels are formed, which enable the components to be flushed thoroughly with a cleaning liquid on all sides.
  • the channels are so large that even a backwash is possible with a comparatively large amount of liquid. As a result, not only product residues are washed away with certainty, but also other foreign bodies. It is also important that the dosing piston does not have to be brought into a special cleaning position for cleaning, but that this cleaning position is also the end position of the suction stroke in the production position, so that also simpler manufacture or simpler
  • the rotary cylinder only needs to have a certain length. It has proven to be advantageous if the rotary cylinder has approximately twice the length of the metering piston.
  • the rotary cylinder can additionally be guided in the housing via cylindrical bearing surfaces arranged at its ends. This has the advantage that the conical outer surface located between the cylindrical bearing surfaces does not need to be machined exactly, but on the other hand can be set very sensitively in the housing, so that the annular surface located between the housing and the conical outer surface of the rotary cylinder is set precisely with regard to its play can be, so that there can be no undesirable clamping of the conical part.
  • the storage of the rotary cylinder in bearing elements of the housing which are preferably formed by plastic-coated bearing rings, on the one hand enables exact storage and, on the other hand, good sealing at this point.
  • the filling device according to the invention can be cleaned particularly simply by circulation cleaning if, according to a further feature of the invention, as is known per se, the rotary cylinder is axially adjustable from a first control position corresponding to a production position into a second control position corresponding to a cleaning position and if in the cleaning position of the rotary cylinder and the metering piston are pulled apart coaxially, the rotary cylinder being approximately a quarter of its length within the associated bearing part provided with supply and discharge connections for the flow of cleaning fluid and the metering piston largely inside the other, also with supply and discharge connections provided for the flow of cleaning fluid bearing part.
  • Suitable device comprising a housing 1 with a relatively large diameter inlet opening 2 and an outlet opening 3 with a smaller cross section.
  • a filling container 5 can be connected to the inlet opening 2, while the outlet opening 3 does not have a shown mouthpiece container can be filled.
  • a rotary cylinder 9 is rotatably mounted and axially displaceable in a manner not shown via a bearing pin 6 and a bearing 7 of a bearing part 8 which is detachably fastened to the housing.
  • the bearing part 8 is provided with supply and discharge connections 11, 12 for a cleaning liquid for purposes described in more detail below.
  • a dosing piston 13 is provided coaxially with the rotary cylinder 9 and is displaceably guided within the rotary cylinder 9 via a piston rod 14.
  • the piston rod 14 is displaceably guided via an actuating mechanism 15, which is only indicated schematically, via a bearing 16 in a bearing part 17 which can be screwed onto the housing 1.
  • the bearing part 17 also has supply and discharge connections 18, 19 for a cleaning liquid.
  • the piston 13 is additionally displaceably guided on the inner wall 21 of the rotary cylinder 9.
  • the rotary cylinder 9 also has a window-like passage opening 22 which is substantially the same size as the inlet opening 2 of the housing 1.
  • bearing rings 23, 24 are provided, each of which cooperate with cylindrical guide surfaces 25, 26 of the outer surface of the rotary cylinder 9 and thus serve to support the rotary cylinder and to seal it from the housing.
  • the conical part of the rotary cylinder 9 need not be machined particularly precisely.
  • the function of the filling device is as follows:
  • Fig. 1 the filling device is shown in the production position, i.e. the rotary cylinder 9 is in the position shown with solid lines.
  • the metering piston 13 seen in the longitudinal direction, closes approximately half of the window-like passage opening 22 or the inlet opening 2, so that the contents are initially prevented from falling in this part.
  • the dosing piston 13 is moved back into its rear position, shown by broken lines, via the piston rod 14, the filling material falls into the interior of the rotary cylinder. It is initially prevented by the wall of the rotary cylinder from exiting into the outlet opening 3.
  • Fig. 2 the filling device is shown in the cleaning position.
  • the rotary cylinder 9 has been adjusted via the bearing pin 6 to the left, so that approximately a quarter of the rotary cylinder is located within the bearing part 8.
