Definitions

  • the invention relates to a device for filling portions of liquid or pasty filling material into containers according to the preamble of claim 1.
  • a known device of this type (DE-OS 30 24 489) is used for filling liquid or flowable or pasty contents, especially in the food industry and the chemical and pharmaceutical industries, and ensures that the metering and filling process with high working speed with gentle treatment of Filling material can be carried out to avoid segregation, at the same time a high degree of dosing accuracy is achieved and infections of the filling material are largely excluded.
  • the shut-off valve contained in the outflow channel is formed by a flat valve plate and a web-shaped guide part guided axially upwards and downwards in an inlet channel of the outflow.
  • the inlet channel opens out into a flow channel with an enlarged diameter, and the transition area between the inlet and flow channel is formed by a horizontal annular shoulder of the outlet housing, which forms a valve seat for the valve plate of the shut-off valve.
  • shut-off valve works properly over a large range of properties of various filling goods to be filled into containers, but that in certain cases, in particular when filling inhomogeneous liquids which contain, for example, fibrous components, such as fruit curd, malfunctions occur in that the valve is not quick enough or not completely closes, with the result of an unpleasant drop formation of filling residues in the outflow area.
  • a device for continuously filling containers with a metered amount of liquid is also known (DE-B-1 251 204), in which the outlet-side shut-off valve has a through-hole for the filling material or the liquid in a guide bore of the same diameter in the outflow channel existing holder supported valve sleeve is formed and the guide bore continues in its outflow end region in an annular valve seat, which cooperates with a valve plate at the outflow end of the valve sleeve as a counter member.
  • the valve seat is formed at the lower end of a valve sleeve which surrounds the valve sleeve on its outer circumference and is spring-loaded, such that the valve sleeve is pressed with its valve seat down against the valve plate in order to hold the shut-off valve in its closed position.
  • the shut-off valve is opened when the valve bushing is pushed upwards through a vessel to be filled pressed down from below, so that the valve seat lifts off the valve disk. In the known device, the shut-off valve thus opens inwards and closes outwards through the valve seat pressed onto the valve plate.
  • the invention has for its object to provide a device of the type mentioned with a simple structure and an improved closing function of the shut-off valve, which avoids undesirable drop formation of filling material residues in the outflow area.
  • the guide bore for the valve sleeve continues in its discharge-side end region in a cutting ring, which interacts with a Gey cutting edge on the discharge-side end of the valve sleeve, care is also taken to ensure that fibrous or other constituents of the liquid with a firmer consistency between the cutting ring and Geyenschneide generated shear are cut to ensure a proper closing of the valve sleeve.
  • the outflow-side end face of the cutting ring can form a valve seat for the valve sleeve, on which the valve sleeve is held in contact with an annular shoulder in its closed position.
  • valve parts are usually made of metal for physiological reasons, a secure metal seal of the valve sleeve on its valve seat is ensured, which is also wear-resistant and aging-resistant. Thanks to this design of the shut-off valve, its closing process can be done very quickly and with a high degree of shut-off security carry out.
  • the metering valve which can be moved up and down in the metering chamber can be designed in the same way as the shut-off valve with a valve sleeve, so that in particular the valve sleeves of the shut-off valve and metering valve are formed from the same parts in the interest of a simple construction of the device and are therefore interchangeable.
  • a distributor plate 1 can be seen in FIG. 1 in the bottom region of a storage container (not shown) for liquid or pasty filling material, to which a tubular body 4 is connected via an intermediate ring 2 with a sealing ring 3.
  • the tubular body 4 is welded to the intermediate ring 2 in the extension of an outlet opening 5 of the storage container for filling material and delimits a metering chamber 6 for the filling material, which is in open connection with the storage container via the outlet opening 5.
  • the tubular body 4 is connected to a welded ring flange 7 with the interposition of a sealing ring 8 with an intermediate plate 9, on which an outflow designated as a whole as 10 is supported for the filling material measured in the metering chamber 6.
  • the outlet 10 comprises a shut-off valve 11 with a tubular housing 12, which is fastened to the intermediate plate 9 by means of a welded-on ring flange with the interposition of a sealing ring 13, and a filling nozzle 14, which is provided with an internal thread Upper end part is screwed with an externally threaded on the outer periphery of the valve housing 12 firmly attached threaded sleeve 15 with the interposition of a sealing ring 16 which is held in sealing engagement with the underside of the valve housing 12.
  • the filling nozzle 14 comprises in its base 17 a ring of discharge pipes 18 for the filling material to be filled into a container 19 placed below.
  • the valve housing 12 and the tubular filling nozzle 14 in turn delimit an outflow channel 20 in which a cylindrical shut-off valve sleeve 21 is supported in a holder 22 formed by the bottom of the shut-off valve housing 12 and can move up and down coaxially.
  • the valve sleeve 21 is guided for its axial up and down movement in a guide bore of the same diameter in the holder 22, which is defined by a cutting ring 23 inserted therein, which protrudes beyond the underside of the holder 22 with a tapered end region 24 to the outlet pipes 18 .
  • the cutting ring 23 interacts with a shear bar which is formed by an end plate 25 which forms a unit with the valve sleeve 21 at the outflow end of the valve sleeve 21.
  • the end plate 25 has a shear region 26 of its outer circumference which adjoins the sleeve body and which can be brought into shear engagement with the inner circumference 27 of the tapered end region 24 of the cutting ring 23 during the closing movement of the valve sleeve 21.
  • the shear region 26 is overlapped by an annular shoulder 28 at the end of the valve sleeve 21, which is worked onto the outer circumference of the end plate 25.
  • the narrow outflow-side end face 29 of the cutting ring 23 forms a valve seat for the valve sleeve 21, onto which it can be placed at the end of its closing movement.
  • the end of the valve sleeve 21 facing the metering chamber 6 is of an open design, while the end of the valve sleeve 21 on the outflow side is closed by the end plate 25 on the underside.
  • a passage opening for the filling material is formed by at least one transverse bore 30 in the wall of the valve sleeve 21 near the end plate 25.
  • One is useful with the transverse bore 30 aligned further transverse bore is provided in an opposite region of the valve sleeve wall.
  • cleaning bores 31 are provided in a uniform distribution on a circumferential circle of the valve sleeve wall.
  • the transverse bore 30 In the closed position of the valve sleeve 21, the transverse bore 30 is held in a sealing manner within the cutting ring 23 and thus prevents the filling material from passing into the part of the outflow channel 20 directly in front of the outflow pipes 18. For a transfer of filling material into this part of the outlet channel 20 from the transverse bore 30 this can be moved out of the cutting ring 23 during the opening movement of the valve sleeve 21 to the outlet pipes 18. This opening movement takes place under compression of a return spring 23 which is attached between the end of the cutting ring 23 facing the metering chamber 6 on the one hand and a spring retaining ring 33 fixed at the end of the valve sleeve 21 on the metering chamber side.
  • a piston 34 is axially movable up and down, which is formed by a support plate 35 and a valve sleeve 21 ', which is identical to the valve sleeve 21 of the shut-off valve 11, as it is by using the same reference numerals for the same or matching parts are identified.
  • the valve sleeve 21 ' is further guided axially up and down in a cutting ring 23' corresponding to the cutting ring 23 of the shut-off valve 11, the return spring 32 in turn being attached between the spring retaining ring 33 and the end of the cutting ring 23 'facing it.
  • the support plate 35 of the piston 34 is provided with an annular seal 36 on its circumference and corresponds in its cross-sectional dimensions to the cross-section of the metering chamber 6.
  • the piston 34 For its axial upward and downward movement in the metering chamber 6, the piston 34 is provided with a rod-shaped actuating device 37 which is fastened to the support plate 35 at its piston end by means of a support device 39 comprising rod-shaped support members 38. Furthermore, the actuating rod 37 is centered through the outlet opening 5 of the Passed through the storage container and connected in a manner not shown with a suitable mechanical, pneumatic or hydraulic actuation or lifting and lowering device for the piston 34.
  • the piston 34 which divides the metering chamber 6 into the two spaces 40 and 41, the volume of which changes correspondingly during the piston movement, forms an automatically opening and closing spring-loaded check valve or metering valve, depending on its upward and downward movement, the transition opening of which for filling material forming transverse bore 30 of the valve sleeve 21 'is normally closed by the position assumed within the cutting ring 23', but is released during the upward movement of the piston 34, which is carried out with movement through the filling material flowing through the opening 5 in the dosing chamber 6.
  • Fig. 1 the piston 34 is shown in a state in which the transition opening or transverse bore 30 between the two metering chamber spaces 40 and 41 is closed by arrangement within the cutting ring 23 'and its sealing system on the end plate 25.
  • a downward ejection pressure is exerted on the piston 34 via the rod-shaped actuating device 37, in which the support plate 35 and the valve sleeve 21 'are held in the fixed mutual association shown in FIG. 1.
  • the filling material contained in the metering chamber space 40 acts on the shut-off valve 11 (shown in the closed state in FIG. 1) by lifting the valve sleeve 21 from its valve seat 29 with compression of the return spring 32, as is the case the detail section according to FIG.
  • the transverse bore 30 at least partially emerges from the cutting ring 23 downwards, and filling material can pass from the transverse bore 30 into the space of the outflow channel 20 directly in front of the outflow pipes 18 of the filling nozzle 14 in order to be filled into the container 19.
  • the return spring 32 of the shut-off valve 11 relaxes and moves the valve sleeve 21 with its end plate 25 while exerting a corresponding suction effect on residues of filling material against the cutting ring 23 in sealing contact with the valve seat 29, the transverse bore 30 again taking up its covered position within the cutting ring 23 .
  • the shut-off valve 11 of the outflow 10 forms a spring-loaded check valve which opens automatically when the piston 34 moves downward under the pressure of the filling material and which closes automatically when the piston 34 moves upward.
  • the upward movement of the piston 34 is terminated and instead the pressure load and downward movement again for dispensing a metered quantity Quantity of product conveyed to a container 19.
  • the return spring 32 of the metering valve relaxes and guides the valve sleeve 21 'onto the valve seat formed by the adjacent end face of the cutting ring 23' to block the transition opening or transverse bore 30 for the filling material.
  • the piston 34 is then in a state ready for carrying out a new working cycle as shown in FIG. 1.
  • the metering valve formed by the piston 34 works in principle in the same fast and reliable manner as the shut-off valve 11, and the valve sleeves 21 and 21 'Are easily interchangeable.
