Subsequently, the butterfly valve 32 again transferred to the open state. The drive 18 moves the moving part 22 with full product storage attached thereto 14 again by 180 ° up in the in 4 shown state. The product transfer system 12 can then be reactivated. Here, the funding promotes 24 that in the product memory 14 located product of the moving part 22 through the wall 16 through into the interior of the filling machine 1 until the product reaches a substantially vertical section of the product transport module 12 passes and the filling device 4 is supplied.

The moving part 22 could also be made in one piece. The provision of a releasable connection part 25 , preferably the butterfly valve 36 as well as the appropriate attachment mechanisms 21 This makes it easier to clean or sterilize. This can increase the ease of maintenance.

In 5 is a turning mechanism 42 for the moving part 22 shown closer. The fixed pipe 28 , which the metering screw of the conveyor 24 encloses, runs in the flange 29 out. At its front side is a seal 50 appropriate. This seal 50 works with the moving part 22 together. The moving part 22 on the one hand also encloses the dosing screw. Towards the stationary pipe 28 the moving part is running 22 also flange-shaped. The moving part 22 is via a fastening mechanism 52 with a carrier 48 releasably connected. As a fastening mechanism 52 For example, a screw or a quick-release screw is used.

The carrier 48 is also sleeve-shaped and surrounds substantially cylindrical a portion of the fixed tube 28 , At the moving part 22 facing side of the carrier runs 48 also in a flange-shaped portion which coincides with the flange-shaped portion of the movable part 22 for fixing by the attachment mechanism 52 interacts. On the carrier 48 is a rotating gear 46 or corresponding teeth or a ring gear arranged. In the 5 are corresponding teeth of the gear 46 indicated. The gear 46 works with a chain 44 together, by the drive 18 can be moved. The from the drive 18 moving chain 46 turns over the movably mounted carrier 48 the moving part 22 , The moving part 22 is through a pivot bearing 56 stored. The storage thus formed 23 is designed as a plain bearing. For this purpose, the pivot bearing encloses 56 the cylindrical portion of the movable support 48 that is between the gear 46 and the flange is located. The pivot bearing 56 is by fasteners 54 with the wall 16 or a corresponding panel connected.

For cleaning purposes, according to the measures already described above, the fastening mechanism 52 solved. This allows the moving part 22 from the carrier 48 be removed. Then there is the flange 29 of the pipe 28 free and can towards the outside of the filling machine 1 be removed. The flange 29 in turn acts with a recess in the carrier 48 together, so when installing the pipe 28 can be pressed against the outside of this recess to achieve the correct mounting position. Subsequently, the moving part 22 put back on and through the attachment mechanism 52 with the carrier 48 screwed. This pushes the moving part 22 about the seal 50 on the flange 29 of the pipe 28 , In that the moving part 22 against the seal 50 in the flange 29 is arranged, is braced, there is a secure seal this separation point.

The device described finds particular use for the delivery of the product to be filled in filling machines in the pharmaceutical field. However, the use is not limited thereto.
