Definitions

  • the invention relates to a device for metering of powdery filling material, as is known from DE 102 11 118 Al.
  • the known device is provided to press the stop ring by means of adjusting against the underside of the dosing.
  • the counterpressing of the stop ring against the underside of the metering disk takes place in order to prevent during insertion of the stuffing die in the openings of the metering that powder passes from the openings in the gap between the bottom of the metering disk and the stop ring.
  • Such powder losses are undesirable on the one hand because the leaked powder contaminates the device, and on the other hand, the loss of powder, especially for relatively expensive pharmaceuticals, represents a significant cost factor. Therefore, a device is desirable which avoids powder losses during insertion of the stuffing dies into the openings of the product container, the device being intended to have a high degree of operational reliability and the device at the same time being designed to be relatively simple in terms of design.
  • the device according to the invention for metering powdery filling material with the characterizing features of claim 1 has the advantage that it holds the closure element gap-free on the underside of the metering chamber during the Einopfvorgangs thanks to the support means for applying a force on the closure element against the stuffing direction of the stuffing die. Thanks to the better closure of the dosing chamber will escape of metered Good difficult. This can reduce the consumption of the goods to be filled.
  • At least one plunger is provided as support means. A pestle can be easily in his
  • At least one wedge is provided as support means, which is preferably designed to be displaceable. Depending on the position of the metering chamber, sufficient supporting force can be exerted indirectly or directly on the wedge via the wedge. In particular, manufacturing tolerances in the distance of the underside of the metering chamber from the table can be compensated for by possibly displacing the wedge slightly further or less far in the direction of its bevelled surface so that the desired force acts on the closure means.
  • At least one spring means is provided as support means, which also exerts a force against the stuffing direction on the closure means.
  • a spring is particularly suitable when the closure means is displaced in order to empty the metering chamber again.
  • the wedge acts on the plunger for applying a supporting force to the closure means.
  • the position of the plunger can be particularly easily changed in Stopfraum by the inclined surface of the wedge cooperates with the lower end of the plunger and the wedge is displaced substantially perpendicular to the stuffing direction for changing the position of the plunger.
  • This arrangement is characterized by a particularly simple design.
  • FIG. 1 shows a longitudinal section of a device according to the invention for metering powdery filling material in the stuffing position
  • FIG. 2 shows the device for dosing powdered filling material before the stuffing process
  • FIG. 3 shows the device for metering pulverulent filling material after the stuffing process.
  • the device 10 shown in the figures for metering powdered product is used in the pharmaceutical industry for the production of drug-filled hard gelatin capsules.
  • the device 10 has a product container 11 for the product, which has a substantially disc-shaped bottom 12 and an outer, vertically encircling boundary wall 13.
  • In the bottom 12 holes are formed as Dosierhuntn 15 or hole groups in each case at equal angular intervals, which cooperate with stuffing dies 17 and transfer stamps 18.
  • Transfer stamps 18 are mounted in spring-loaded stuffing stamp carriers 19 as well as transfer stamping carriers 20, which in turn are fastened together on a cross-beam 22.
  • the cross-beam 22 is mounted in columns 23, 24 and movable up and down in the direction of the arrow 25.
  • a closure means 1 is provided in the outer region, which comprises at least one opening 8 for the possible emptying of the metering chamber 15.
  • the capsule part carrier 30 has in registration with the metering chambers 15 receptacles 31 for capsule parts, which is part of already are addressed hard gelatin capsules. For dosing the contents in the capsule bases of the product container 11 is gradually rotated by a coupled with a motor, not shown drive shaft 32 under the respective stuffing die 17 and transfer stamp 18.
  • the closure means 1 acts as an abutment.
  • the pressed powder compact is pushed over by the transfer stamp 18 during its downward movement into the respective capsule lower part which is provided in the capsule sub-carrier 30.
  • the capsule part carrier 30 together with the filled capsule lower parts is pivoted out of the region of the product container 11 in order to place the corresponding capsule upper parts on the capsule lower parts.
  • the device 10 Due to a gap between the bottom 12 of the product container 11 and the closure means 1, in particular when lowering the stuffing die 17 into the metering chambers 15, powder losses may occur due to the stuffing punch pressure. This powder passes from the holes 15 into the gap and is distributed from there via the closure means 1 and the entire device 10. To avoid or reduce these powder losses, the device 10 according to the invention is particularly adapted.
  • Stopfraum exerts on the underside of the closure means 1.
  • the spring means 6 is for this purpose connected to the underside of the closure means 1.
  • a plunger 2 is arranged substantially on the axis of the stuffing die 17. With its end face, the plunger 2 counteracts a displacement of the closure means 1 downwards in the stuffing direction.
  • the another end face rests on the inclined surface of a wedge 5.
  • the oblique surface of the wedge 5 opposite side is arranged on a table 7, which can not be moved in the direction of stuffing with respect to the closure means 1.
  • the wedge 5 can be moved substantially perpendicular to the stuffing direction on the surface of the table 7.
  • These support means 2, 5, 6 for applying a force to the closure means 1 against the stuffing direction of the stuffing die 17 operate as follows.
  • the stuffing position is shown.
  • the stuffing die 17 compresses by one or more downward movements located in the metering chamber 15 Good.
  • the closure means 1 is in the stuffing position, in which it closes the underside of the metering chamber 15 designed as a bore.
  • the stuffing die 17 exerts force in the stuffing direction on the closure means 1 in order to keep a possible gap between the closure means 1 and the underside of the metering disk 34 as small as possible, especially when plugging, a force is generated against the stuffing direction via wedge 5 and plunger 2 applied the closure means 1.
  • the wedge 5, as shown in Figure 2 moved to the left until the plunger 2 wedged between the closure means 1 and 5 wedge or table 7. This position is shown in FIG. Then the already described stuffing process of the metering chamber 15 can begin. If the stuffing process is completed, the dosing chamber 15 located under the stuffing die 17 should be brought into the next working position. In order to move the metering disc 34 in this next position, the plunger 2 is again brought into a position in which it no longer applies force to the closing means 1 and on the underside of the metering disc 34. For this purpose, the wedge 5 is again moved to the right, as indicated in FIG. 3, so that the plunger 2 releases from the wedged position and moves downward and is no longer in contact with the closure means 1. When the position shown in Figure 3 is reached, the metering disk 34 can be brought into the next working position, in which, for example, located in the metering chamber 15
  • the closing means 1 still closing the metering chamber 15 is displaced outwards in such a way that the opening 8 is in register with the metering chamber 15.
  • the transfer punch 18 is lowered, whereby the metering chamber 15 is completely emptied.
  • the device 10 according to the invention can be modified in many ways, without departing from the inventive idea, which is to press the closure means 1 against the underside of the metering chamber 15 during the metering of the filling powder into the metering chamber 15, so that no filling material at the
