Definitions

  • the present invention relates to a means for dosing a predetermined quan ⁇ tity of powder or granular material.
  • the object of the present invention is to fulfil the above-mentioned de ⁇ sired and this is achieved by arranging an aperture or pipe for a cylinder with an adjustable circumferal groove, between a store and a discharge means located one immediately above the other.
  • the cylinder is movable in said aperture between the two spaces in such a way that in one position the circumferal groove is in the store and in a second position it is in the discharge means.
  • Said aperture has only sufficient room for said cylinder.
  • the store may be provided with a control means so that the material in the store flows at an angle towards said cylinder.
  • the discharge means cooperates with a container movable between the discharge means and a discharge station where it is emptied into a container.
  • This emptying is preferably via a mixer arranged symmetrically in relation to the container and being identical in appearance to the container opening except that its dimension is smaller than the actual opening of the con ⁇ tainer. This avoids spilling outside the opening of the container.

  • the upper part 11 is conically bevelled at the bottom, and this bevelled part is designated 12.
  • Above the cone is a control means for the material flow towards the cylinder 6,11.
  • the control means consists of a conical hood 18 provided with openings 19 at its periphery. The hood is connected at the top to a pipe 17 through which leads an operating rod 16, connected to the cylinder 6 and 11.
  • the lower end of the cylinder.6 and 11 is provided with guide blades 13 joined to a tube 14.
  • the tube 1 is in turn joined at the lower end to a discharge tube 15. When the cylinder 6,11 is displaced, the tube 14 and discharge tube 15 are
  • the dosing means described above functions as follows. First the width of the circumferal groove 7, 8 and 12 is set by turning the two cylindrical parts 6 and 11 in relation to each other. The dosing quantity is deter- mined by the width of this groove. The cylinder 6,11 is moved by an operating rod to the position shown in Fig.2. If the store is filled with material, this will be supplied through the openings 19 from the side to the circumferal groove. The material supplied to the groove is not sub ⁇ jected to the full pressure of the material in the store, thanks to the protective . conical hood 18. If the operating rod 16 is moved down, the circumferal groove 7, 8 and 12 will arrive in the aperture 5. There is thus a limited quantity of material in the groove. Once the groove arrives on the other side of the aperture 5, the material will be transferred to the discharge means and the discharge tube 15. The desired quantity then arrives on the conveyor belt 4.

  • the container 23 is provided at the side with a toothed wheel 25 cooperating with a rack 26.
  • the container 23 can be forced into a receiving position by the toothed wheel 25 and rack 26, as shown in Figs.4 and 6 or into a discharge position as shown in Figs.5 and 7, where the axis of the discharge aperture is quite vertical.
  • a receiving unit such as a • container 22, or a mould, is provided at the discharge station.
  • the opening of the mixer has the same appearance as that of the container 22.
  • the dimension of the mixer opening is slightly less than that of the container opening in order to prevent spilling outside the container 22.
  • the powder in the container 23 is below the centre of rotation. This means that when transferred from horizontal transport to rotation, it will not change position because of the centrifugal force and retardation force.
  • container 23 with mixer can be used for applications other than that described above.

Abstract

La présente invention permet de prélever d'un magasin (1) une quantité prédéterminée d'un matériau pulvérulent ou granulaire. On obtient cela à l'aide d'un magasin (1) et d'un organe de décharge (3) disposés l'un sur l'autre et reliés par une ouverture (5) pour un cylindre (6 et 11) possédant une rainure de circonférence (7, 8 et 12), lequel cylindre (6 et 11), lorsqu'il se déplace dans l'ouverture (5), entraîne avec lui du matériau du magasin (1) à l'organe de décharge (3).
