Definitions

  • shut-off options for containers of such substances provide seals that can be rubbed off, in particular rubber or rubber-like seals. If abraded particles penetrate into the fabric, they are often extremely dangerous for its further processing, especially if highly stressed components made from such fabrics still contain abrasion particles of the type mentioned in the end product.
  • the object of the invention is to provide a device according to the preamble of claim 1, which enables a vacuum-tight delivery of a viscous substance and prevents abrasion of particles of the sealing material such as rubber and thus an impairment of the material to be processed.
  • the sealing plate of the shut-off device In one position ( «open») or in the other position ( «closed •) the sealing plate of the shut-off device is pressed against the relevant sealing surfaces (sealing flange) by the filling pipe.
  • the device can be shut off immediately vacuum-tight; the vacuum tightness is facilitated in that the shut-off means has no passage to the outside. Furthermore, the shut-off device of the device can be closed very quickly.
  • the device has a shut-off means 4 - hereinafter referred to as “another shut-off means” - which consists of two hardened metal disks 2 and 3, between which a hardened control slide is movably arranged.
  • the hardened metal disks 2, 3 are braced against one another with tension springs 5 without play.
  • the control slide further shut-off means 4 can be operated by means of a transmission linkage 7 and a piston 6 pressurized by compressed air, which works against a compression spring 8, which brings the further shut-off means 4 back into the closed position when the air pressure of the compressed air is reduced.
  • a nut 10 to actuate the transmission linkage 7 manually (for example in the event of a fault or failure of the pneumatics or the compressed air) and thus to bring the control slide of the further shut-off means 4 into any desired position.
  • a metal bellows 9 which is tightly welded to the housing 1 of the device and to the transmission linkage 7, a wear-resistant seal from an evacuated housing 1 or from the storage container 38 to the atmosphere is achieved.
  • the storage container 38 which carries the viscous substance to be filled or metered, such as powder metal or other viscous sensitive substances, has a filling funnel 37 according to FIG. 1.
  • the cylindrical part of the receptacle 38 adjoins the filling funnel 37 upwards.
  • the one shut-off means 21 has a movable sealing plate and a filling tube 22, the sealing plate is connected by means of wire pins 20 to a fork head 19, which is actuated by an actuating rod 15 in the desired position relative to a sealing flange 24 - at the end of the filling funnel 37 - or from a body 23 of the device can be brought away.
  • the actuating rod 15 has, on the side facing away from the fork head 19, two annular grooves 16 which hold the rod 15 in the two positions «on and « to the one shut-off means 21 in an actuator support plate 13.
  • the actuating rod 15 is locked with a bolt 14.
  • control slide 4 further shut-off means 4 must be moved out of the closed position shown in the drawing.
  • an actuation lock 27 is provided which can be triggered manually by means of a button 17 on the actuation rod 15 of the one shut-off means 21. With the lock 27 is in the vacuum-tight shut-off position of one shut-off means 21 moved downward Cross member 28 a locking yoke 12 slipped over a pin 11 which engages the actuating rod 7 of the control slide further shut-off means 4.
  • the filling tube 22 is detached in a receptacle 26 from the sealing plate of the one shut-off means 21 and the sealing plate in question can now be pulled into the open position with the actuating rod 15 and the wire pins 20.
  • the sealing plate slides on ball guides 30, 31, 32 and 33. This results in rolling friction and therefore no abrasion or other wear, and «jamming of the parts together is impossible.
  • the actuating rod 15 can then be pressed down so that it is guided with its relevant annular groove 16 into the actuator support plate 13 and can be locked again.
  • the bolt 14 is entangled by means of spring force on the actuating rod 15 and also locked.
  • the sealing rings 25 and 34 reliably prevent powder or liquids or other medium from penetrating into the space 35.
  • a membrane 36 is provided, in which the filling pipe 22 is guided so that it can be connected to a receptacle 39 in an elastically sliding manner, vertically movable and in a vacuum-tight manner.
  • the pneumatic actuation (piston 6) enables a sensitive adjustment and very quick closing of the control slide of the further shut-off means 4 responsible here for the metering of material. Pneumatic actuation could also be provided for the one shut-off means 21.
  • An electromechanical or hydraulic control, actuation of the device would also be applicable, as would a mutual electromechanical lock for the actuation of one (21) and further shut-off means 4 and / or a jointly or independently actuated control system for quantity and / or volume metering of the respective substance.
  • the filling tube 22 can be connected directly to a packaging device or to a further processing or processing device for the material discharged and / or dosed from the receiving container 39.
  • the device according to the invention is particularly well applicable for powder metal processing but also glass, ceramics or other powdery, granular or otherwise particulate materials or other viscous substances, such as melting of certain metals, such as, for. B. mercury or pastes or poorly flowing pharmaceutical preparations or similar substances.
  • a normal horizontal guide could also be provided and the filling tube 22 could in turn be provided with a cylindrical spring (helix) which surrounds it concentrically and which seals the sealing plate of the one blocking means 21 presses, provided.
  • tension springs with said cylindrical compression spring could also be combined and used, or a compression spring in the space 35 could surround the lower conical end of the central sealing flange 24 so that the sealing plate in question is pressed against the filling tube 22 (essentially vertically) .
  • the entire device does not have to have a vertical main axis for the shut-off and metering device, as shown in FIG. 1, but this could also be carried out almost horizontally or in a different inclined position and thus work.
  • bellows 9, 18 made of metal
  • simple plastic bellows can be used as a cover for z. B. each serve a plate spring assembly or the like, concentrically surrounding the actuating rods 7 and 15, respectively.
  • the control slide of the further shut-off means 4 can also be mounted on rollers or balls in a manner similar to the sealing plate of the one shut-off means 21.
  • the slide or plate materials can be selected in a suitable manner known to the person skilled in the art, so that there is no abrasion by the valve actuation. Of course, this also includes the adjustment of the slide or plate materials to the seat materials. What is essential is particularly easy sliding or rolling on the sealing elements mentioned; if necessary, there is no need for sealing rings, depending on the application or the pressure difference from the atmosphere.
  • the filling tube 22 can be closed at the bottom by a stopper and also evacuated, even after connection to the receptacle 39 or a device for receiving the goods to be filled, such as collectors, molds, etc., which can fit tightly against the membrane 36 from below.
