  • the housing has two [56] References Cited parallel rows of outlet apertures connectable with the con- UNITED STATES PATENTS tainers which receive the dosages expelled by the cooperation of the two cocks from the chambers 1n the main cock.
  • the invention relates to a dosaging device for viscous substances with at least one rotary slide valve, in whose housing a main cock and an auxiliary cock are rotatably arranged coaxially independently of one another, whereby in the main cock at least one chamber is recessed which extends over a sector angle of approximately 180, and in which is positioned a displacement sector formed by the auxiliary cock and fixedly connected with a shaft, said displacement sector extending over a sector angle of approximately 90, and whereby in the housing an inlet aperture is provided, through which the viscous substance to be dosaged is drawn by means of the displacement sector into a part of the chamber corresponding to its angle of rotation, as well as an outlet aperture, through which the dosage of the substance measured thereby, by means of the displacement sector is forced out of the chamber part and through an outlet pipe arrives at a vessel to be filled.
  • two rotary slide valves are arranged as twins adjacent one another, in order to fill at the same time a plurality of containers arranged in two rows with a predetermined dosage of the viscous substance, whereby during each operative cycle of a rotary slide valve from each chamber only one dosage is ejected.
  • the present invention insures in very simple manner, a doubling of the output of the previous devices, or in making use of a single rotary slide valve only of the same size instead of two rotary slide valves, although providing the possibility of providing in the dosaging device of the invention two rotary slide valves.
  • the invention is distinguished by an inlet aperture which extends at the periphery of the two cocks over a sector angle of approximately 90", and that in the housing outside of the mentioned outlet aperture, still a second outlet aperture is provided in addition to the mentioned outlet aperture, however, no ventilation aperture, so that with each operative cycle of the cock, a dosage of the substance is forced through each of the two outlet apertures.
  • FIG. 1 illustrates a vertical section of a rotary slide valve for a dosaging device along the line II of FIG. 2.
  • FIG. 2 illustrates a vertical section along the line lIII of FIG. I and FIGS. 30, 3b, 3c and 3d illustrate each a diagrammatic sectional view corresponding to FIG. 2, namely, for four different operative positions of the rotary slide cock.
  • the dosaging device illustrated in the drawing has a rotary slide valve 1, which is arranged on the lower end of a supplyfunnel 2.
  • the rotary slide valve 1 has a housing which by screws, indicated solely by their center lines 4, is secured to a horizontal frame 5 having an aperture in which the lower end of the funnel 2 is mounted, which communicates with an inlet aperture 6 of the housing 3.
  • the interior of the housing 3 con tains a rotary slide cock 7, which consists of two coaxial parts 8 and 9 rotatable oppositely to each other.
  • the part 8 is designated in the following as main cock and consists of a circular-cylindrical body, in which four axially alined chambers 10 disposed parallel adjacent one another have been produced by a milling operation.
  • the chambers 10 extend each over a sector angle exceeding somewhat 180 to a chord ll of the cylinder-cross-section adjacent to the diameter.
  • the chambers 10 are separated from one another by three partitions 12, whereby the two outer chambers 10 are limited by the end portions 13 and 14 of the member 8.
  • the main cock 8 is rotatably joumaled on the shaft 15 and extends on its outer periphery at a sector angle of over 180 along a cylindrical inner surface 16 of the housing, and indeed, with a play of preferably about 0.1 to 0.3 mm.
  • the part 9 of the rotary slide cock 7 is designated in the following as auxiliary cock and comprises the shaft 15 and four similar displacement sectors 17 which extend into the chambers 10, and are fixed on this shaft 15.
  • the sectors 17 extend each over a sector angle of somewhat beyond whereby between them and the inner circumferential housing surface 16 or the partitions 12, respectively, again a play of about 0.1 to 0.3 mm. is provided.
  • each chamber 10 On the lower side of the housing 3 are provided for each chamber 10 two outlet apertures 18 and 19, to which funnelshaped outlet pipes 20 are attached. Accordingly eight funnels 20 are present in all which serve for the simultaneous filling of eight containers, not shown, for example, eight deeply dished cans made of a synthetic foil, which in known manner, are still connected with the foil, and placed under the funnels 20.
  • the funnels 20 are removably mounted so that they may easily be replaced by other funnels corresponding in each case to the inlet aperture of the receptacles to be filled.
  • the end portion 13 and 14 of the member 8 are provided each with a pair of annular seals or packings 22 which are disposed between member 8 and housing 3.
  • the packings 21 and 22 are inserted in annular grooves of the body 8, but they could also be disposed in annular grooves of the shaft, or of the housing 3, respectively, or in annular grooves of bushings mounted on the member 8.
  • channels 26 which insure the introduction of a sealing fluid into the annular groove 24 and accordingly also in the other annular groove 23.
  • the sealing fluid which stands under a slight excess pressure and preferably consists of a greatly diluted disinfecting solution, prevents an escape of the substance to be dispensed in dosages as described, for example, of butter or jogurt from the interior of the rotary slide valve 1.
  • a pinion 27 fixed on the end portion 13 and which is in engagement with a toothed rack bar 28.
  • the toothed rack bar 28 is moved to and fro by the piston of a doubly-acting, pneumatic cylinder 29.
  • a pinion 30 which is fixed on the shaft 15, and is in engagement with a toothed rack bar 31.
  • the toothed rack bar 31 is moved to and fro by the piston of a doubly-acting pneumatic cylinder 32, whereby it carries out on the forward path as well as on the return path two steps, whose length may be continuously altered by a hand-wheel 33, for example, by adjustment of stop members.
  • FIG. 3a shows the rotary slide cock 7 in the same position as in FIG. 2, wherein the somewhat semicylindrical solid part 8a of the cylindrical member 8 which remained after the milling operation forming the chambers 10 is rotated up to the outlet openings 18 which all are disposed consecutively in a row, without, however, covering these outlet apertures 18.
  • the sector 17 is disposed in starting position to the right above in the chamber 10.
  • the cylinder 32 and the toothed rack bar 31 rotate the auxiliary cock 9 about an angle which is adjusted by the hand wheel 33 in the direction of the arrow 34 of FIGS. 3a and 3b, so that the viscous substance 35 in accordance with FIG. 3b is drawn into the right hand upper part of the chamber 10, while at the same time the substance which was delivered by a previous operative cycle according to FIG. 3a into the left hand lower part of the chamber 10 is forced out through the aperture 18.
  • the cylinder 29 and the toothed rack bar 28 rotate the main cock 8 in direction of the arrow 36 (FIG. 3b) and moves with the part 8a up to the outlet apertures 19 without, however, covering the same, as shown in FIG. 3c.
  • the auxiliary cock 9 is rotated further in the direction of the arrow 34 up to the suction position shown in FIG. 30.
  • FIG. 3d shows the condition at the end of the rotary movement in direction of the arrow 37.
  • FIGS. 30 and 30, or the FIGS. 3b and 3d, respectively show the two-part rotary cock 7 in positions symmetrical to the vertical axial central plane of the rotary slide valve 1, and that with each operative cycle, each chamber 10 pushes the substance 35 for two cans from the device, one through the aperture 18 and the other through the aperture 19.
  • the size of the can to be filled is dependent on the size of the angle about which the auxiliary cock 9 is rotated when the main cock 8 remains stationary (between FIG. 3a and FIG. 3b, or FIG. 30 and FIG. 3d, respectively), namely from the adjustable size of the first stroke of the entire stroke of the cylinder 32 and the toothed rack bar 31, respectively.
  • the inlet aperture was only about as wide as indicated in dotted lines in FlG. 3a and designated with 6a. Furthermore, in place of the outlet aperture l8, solely a ventilation aperture 39 indicated by dotted line, and of very small cross-section was present, through which upon rotation of the sector 17 from the position of F IG. 3a into that of FIG. 3b, air was blown out, which was present in the lower empty part of the chamber 10. A substance dosage was only discharged upon the movement of the sector 17 from the position shown in FIG. 30 into that of FIG. 3d through the aperture 19, while through a further ventilation aperture 40 indicated in FIG. 3d, air could enter into the part of the chamber 10 which was emptied.
  • a further very great advantage of the present dosaging device is that it may very easily be cleaned, for example, in that steam is introduced through the inlet 6 and is blown through the housing while the cocks 8 and 9 are being rotated, without any dismounting of parts being necessary.
  • steam is introduced through the inlet 6 and is blown through the housing while the cocks 8 and 9 are being rotated, without any dismounting of parts being necessary.
  • the range of utilization of the present dosaging device is appreciably greater than that of the device previously known.
  • main cock 8 consists of one single piece
  • same may obviously also consist of several parts fixedly connected with one another, by screws or the like.
  • auxiliary cock 9 could also be made from one single piece.
  • an agitator means or a worm rotatable about vertical axis is arranged in the funnel 2 in order to feed the viscous substance to the inlet aperture 6, because the specific weight of the substance in many cases may not be sufficient for this purpose.
  • a dosaging device for viscous substances comprising a cylindrical housing having a substantially horizontal axis, a rotary slide valve member in said housing, a shaft extending through said valve member in concentric relation to said valve member and said cylindrical housing and being freely rotatable in said valve member, at least one chamber in said valve member extending inwardly from the peripheral surface thereof to said shaft and circumferentially through an angle of approximately 180, a vane in said chamber secured to said shaft and having an axial width substantially equal to that of said chamber and an angular dimension of approximately said housing having a top inlet opening and two bottom outlet openings spaced from each other circumferentially of said housing, means for intermittently causing rotary reciprocation of said valve member and said shaft with the vane in relation to each other to introduce doses of material into said chamber alternately at one side of said vane and the other and to discharge said doses alternately through said two bottom openings of the housing, a pair of annular sealing means spaced from each other between said valve member and said shaft adjacent each end of
