Definitions

• the invention relates to a portioning unit for a filling system for filling cans with a viscous, pasty or lumpy filling material, with at least one cylinder unit guided past a sealing plate.
• the object of the invention is to create a positioning unit in which the pressure with which the sealing plate is pressed against the open end of the filling cylinder fulfills these requirements.
• this object is achieved in a first embodiment by means of a lower part which is provided with a first bore for the filling material and which is provided with an annular spring which is arranged concentrically with the first through hole, and which is designed with a second through hole for the filling material , the sealing plate-carrying upper part, which is provided with an annular groove concentrically arranged with the second through hole and receiving the ring spring, the depth of the ring groove being greater than the height of the ring spring and the ring groove receiving an elastic ring hose.
• a second exemplary embodiment is characterized by a lower part formed with a first through-hole for the filling material, which is provided with an annular groove arranged concentrically to the first through-hole, and an upper part designed with a second through-hole for the filling material, which has a concentric is arranged for the second through hole arranged, engaging in the annular groove, wherein the depth of the annular groove is greater than the height of the annular spring and the annular groove receives an elastic ring hose. It is also proposed that the ring hose be filled with air.
• FIG. 1 shows a filling system designed with a portioning unit according to the invention
• FIG. 3 shows a representation corresponding to FIG. 2 with the upper part lowered
• FIGS. 2 and 3 shows a representation corresponding to FIGS. 2 and 3 when the hose is defective.
• Fig. 1 shows a system for filling cans with a viscous, pasty or lumpy filling material, which consists of a with a lower part 12, an upper part 18 and a plurality of Greincm 2, which are guided past the sealing plate 22.
• the filling cylinders 24 are provided with sealing flanges 26 which slide on the sealing plate 22, with each filling cylinder 24 carrying out a quantity of the filling material with each filling operation records how it should later be placed in a tin.
• the sealing plate 22 In order to enable a reliable transfer between the upper part 18 of the positioning unit and the filling cylinder 24, the sealing plate 22 must be pressed against the sealing flanges 26 of the filling cylinder 24 with a suitable pressure. This pressure must be so great that the filling material does not escape between the sealing plate 22 and sealing 2: 6. On the other hand, this pressure must not be too high, since the sliding movement between the sealing flanges 26 and the sealing plate 22 must be guaranteed.
• annular groove / ring spring configuration is provided between the lower part 12 and the upper part 18 of the positioning unit.
• the depth of the annular groove 20 is greater than the depth of the annular spring 14, so that a space remains between the surface of the annular spring 14 and the bottom of the annular groove 20 even when the upper part 18 is in contact with the lower part 12. In this remaining space, an annular tube 28 is inserted, which is filled with air.
• DExr annular tube 28 thus presses the upper part 18 with the af this resting sealing plate 22 from the base 12 in a direction towards the sealing flange 26, wherein de / r contact pressure between the sealing plate 22 and the Dicht ⁇ flanges 26 from the pressure at which the ring hose 24 is acted on, results.
• the annular groove 20 can optionally be arranged in the upper part 18, as shown, the annular spring 14 being a component of the lower part 12. However, the annular groove 20 can also be formed in the lower part 12, while the annular spring 14 is formed on the upper part 18.
• Fig. 3 illustrates that when the pressure in the ring hose 28 is reduced, the upper part 18 can be lowered onto the lower part 12, for example for maintenance or cleaning work.
• the proposed design of a portioning unit thus enables filling material in a filling system, in which filling cylinders are guided past a sealing plate, to be pressed onto this sealing plate with a predetermined pressure, the function being ensured in any case even if the pressure medium fails is.
