  • the metering device 4 illustrated in more detail in FIGS. 2 through 4 is provided with a metering cylinder 6 , a valve cylinder 7 arranged coaxially therein, and a ring-shaped metering piston 8 that is movable within an annular chamber 9 extending between the metering cylinder 6 and the valve cylinder 7 in such a way that the metering piston 8 , in accordance with the cycle control of the filling device 1 , assumes an upper intake position and a lower dispensing position and, accordingly, conveys a product quantity, respectively, out of the product reservoir 3 .
  • the metering piston 8 divides the annular chamber 9 into an upper part connected in a passage area 10 to the product reservoir 3 and a lower part forming the metering chamber 11 for the product.
  • the metering chamber 11 in the metering cylinder 6 is closed at the bottom side by a mouthpiece 13 with the exception of a coaxial cylindrical dispensing opening 12 .
  • a central valve piston 15 is provided that is axially movable between a lower closing position (metering device 4 . 2 ) engaging the dispensing opening 12 of the mouthpiece 13 and an upper release position (metering device 4 . 3 ).
  • This configuration of the metering device 4 that is referred to as a piston metering device is disclosed in principle in EP 0 286 785 A2.
  • valve cylinder 7 and the valve piston 15 are combined into a central module so that the constructive expenditure for manufacturing the respective modules can be significantly reduced by simpler individual parts, in particular, turned parts.
  • the assembly comprised of the metering cylinder 6 , the metering piston 8 , and the piston-cylinder unit 7 , 15 , provided especially as a monolithic part, is arranged coaxially to an outer supply cylinder 16 connected with its top to the product reservoir 3 and extending between a bottom plate 17 of the product reservoir 3 and a securing plate 18 of the filling device 1 provided with the mouthpiece 13 .
  • a supply chamber 20 is created that surrounds as an annular chamber the metering cylinder 6 .
  • the metering cylinder 6 is moveable according to the direction of arrow D from a lower closing position (according to metering device 4 . 1 , FIG. 2 ) into an upper opening position (metering device 4 . 3 , FIG. 3 ).
  • the end face of the metering cylinder 6 engages the mouthpiece 13 so that the inner metering chamber 11 is closed relative to the surrounding annular supply chamber 20 .
  • the upper opening position of the metering device 4 In the upper opening position of the metering device 4 .
  • the metering chamber 11 communicates with the surrounding annular supply chamber 20 within the supply cylinder 16 via a supply opening 21 , wherein this supply opening 21 extends between the end face of the metering cylinder 6 and the mouthpiece 13 .
  • the metering device 4 . 1 shows the valve piston 15 in its upper opening position in which the dispensing opening 12 of the mouthpiece 13 is open relative to the metering chamber 11 .
  • the metering cylinder 6 is positioned in its lower contact position and rests against the mouthpiece 13 so that the connection between the supply chamber 20 and the metering chamber 11 is interrupted.
  • the metering piston 8 is moved by an advancing movement illustrated by arrow A to such an extent that the product contained in the metering chamber 11 is moved in a dispensing direction indicated by several arrows P and is conveyed through the dispensing opening 12 via the mouthpiece 13 into the cup 5 .
  • the metering piston 8 reaches the lower push-out position illustrated in metering device 4 . 2 in which a product quantity that has been precalculated based on the metering chamber 11 and the stroke of the metering piston 8 is dispensed into the cup 5 .
  • the valve piston 15 can become active in that it is moved in the direction of arrow K so that the dispensing opening 12 in the area of the mouthpiece 13 is closed.
  • the subsequent movement phase is illustrated in FIG. 3 wherein the valve piston 15 now remaining in the closing position in the mouthpiece 13 is illustrated clearly.
  • the metering cylinder 6 by introducing a movement according to the direction of arrow D, as well as the metering piston 8 , by introducing a movement according to arrow B, are moved simultaneously or sequentially upwardly. In this way, the movement according to arrow D first opens the gap-shaped area of the supply opening 21 in order to repeat a product supply.
  • This new product supply into the metering chamber 11 is illustrated in more detail with the aid of the metering device 4 . 4 in FIG. 3 , wherein, for taking in the product, a further movement of the metering piston 8 in the direction of arrow B′ is provided and the product that has been sucked in from the product reservoir 3 passes the annular passage area 10 , reaches the supply chamber 20 , and, by moving through the latter, fills the metering chamber 11 via the supply opening 21 . In the upper part of the annular chamber 9 , the product that also surrounds the metering piston 8 at the backside is pushed back via the openings 14 , 14 ′ out of the annular chamber 9 into the container 3 .
  • the movement of the metering cylinder 6 (arrow D) according to the present invention is advantageous because its distance S in the area of the annular supply opening 21 can be matched with minimal expenditure to the consistency of the product being processed.
  • the gap size S can be kept small, for example, for liquid products; for pasty products, it can be enlarged accordingly.
  • this adjusting possibility is useful in particular when products with solid components, for example yogurt containing fruit, is to be dispensed.
  • the gap size S can be matched to the size of the fruit so that accidental crushing of the fruit or jamming in the gap area can be reliably prevented.
  • the metering piston 8 After the metering piston 8 has reached its upper end position that is determined in accordance with the metering volume of the metering chamber 11 upon movement according to the direction of arrow B′, in accordance with a substantially reverse sequence of the above described movement sequences initially the metering cylinder 6 is lowered opposite to its lifting movement D and, in this way, the connection between supply chamber 20 and metering chamber 11 is interrupted, wherein the terminal edge of the metering cylinder 6 can comprise a profiled configuration in the form of a cutting edge that cooperates with the mouthpiece 13 .
  • valve piston 15 In the contact position of the metering cylinder 6 , the valve piston 15 can be lifted opposite to its lowering movement K so that the dispensing opening 12 in the area of the mouthpiece 13 can be released for the dispensing phase illustrated with the aid of the metering device 4 . 1 ( FIG. 2 ) and the filling process to be performed can be realized by lowering the metering piston 8 .
  • metering device 4 . 5 illustrates schematically a movement phase of the assembly required for cleaning the dispensing device 1 after a long period of use.
  • the valve piston 15 and the metering cylinder 6 are axially movable into an upper service position wherein at the same time the metering piston 8 is moved into a lower service position.
  • the valve piston 15 is retracted completely into the metering cylinder 6 so that these two parts are positioned at a spacing above the metering piston 8 and, in this way, a rinsing agent, for example, for steam cleaning, allows complete cleaning of the components even in the gap E.
  • the correlated drive members G, G′, G′′ ( FIG. 2 ), not illustrated in greater detail, are designed such that particularly the metering cylinder 6 can be moved into a position above its opening position ( FIG. 3 , metering device 4 . 4 ) in the supply phase provided during the filling process.
  • the metering piston 8 is adjustable such that it is located above the mouthpiece 13 without contacting it.
  • FIGS. 5 and 6 a different embodiment of the metering device 4 is illustrated; it is provided with a mouthpiece 13 ′ that is supported seal tightly in the lower end area of the supply cylinder 16 so as to be axially movable.
  • the mouthpiece 13 ′ can be moved together with the metering unit that is comprised of the metering piston 8 , the metering cylinder 6 , and the valve piston 15 from an upper starting position into the illustrated lower dispensing position in an axial direction (movement arrow F).
  • FIG. 5 shows in analogy to the illustration of FIG. 2 (metering device 4 . 1 ) the filling phase for the product P wherein the mouthpiece 13 ′ is immersed to an appropriate depth into the cup 5 ′.
  • the mouthpiece 13 ′ embodied like a movable nozzle is expedient in particular when the product P is to be filled into the cup 5 ′ by a so-called bottom filling action.
