Definitions

  • Dosing device on a filling system in particular for liquid and pasty products and processes for their operation
  • a large number of metering devices for liquid or pasty products are known, for example according to Swiss Patent Nos. 540 478 or 555 043, these metering devices working by means of an extendable bellows and the entire outlet valve being moved up and down , the stroke determines the volume of the product to be filled.
  • an inlet valve is opened and the outlet valve is closed, the bellows being pulled out, while when emptying, the inlet valve is closed and the outlet valve is open and the bellows chamber is shortened.
  • the maximum frequency is limited by the fact that in order to fill the bellows chamber with the dosing volume, it must be moved downwards and the process takes a relatively long time.
  • DE-B-2 218 864 describes a metering device using a rotary slide valve for filling milk, with a housing connected to a liquid supply with a continuous cylindrical bore, the hollow rotary slide valve alternately establishing the connection to the liquid supply and again closes.
  • a metering device allows a relatively high filling frequency, but is only suitable for liquids and neither for pasty products nor for liquids containing solids such as yoghurt, soups or the like.
  • a metering device which works by means of a vertically operating metering piston, the shut-off valve being formed by a horizontally mounted shaft which has a through bore which, when this bore is in a suitable position, the liquid enters a filling head provided with a shut-off valve.

  • the shaft 1 has a storage container 1 which is fed via a fixed feed pipe 2 such that the level of the product 23 is always above the shaft 3.
  • the shaft 3, which is driven by a manual geared motor 4, has one or more, in the present case two, continuous, cylindrical bores 5 which, together with the stroke of the double-acting piston 6, result in the metering volume.
  • the outlet pipe 7 has a shut-off valve 8 known per se and opens into a filling mouthpiece 9.

  • Both the actuating rods 10 and the shaft 3 are suitably supported, these details not being drawn in the schematic representations and being known per se.
  • the motor 4, the gearbox and the bearing are mounted outside the housing and a vapor barrier 24 is expediently arranged between these parts and the interior of the housing.

  • a locking ring 12 is inserted at the top and bottom to secure the path of the piston 6 upwards and downwards.
  • three pins can also be used.
  • the piston itself has a seal 13.
  • an actuating frame 14 is fastened, which has three legs 15 which act directly on the piston 6.
  • this tripod means that the rod has a low weight and on the other hand that the piston can be actuated without the risk of canting or jamming.
  • the shaft 3 is held by means of a bearing 16, which has a seal " 17 on each side of the outlet 7, which can either be attached to the shaft or to the bearing, but which can also be omitted.
  • the mode of operation of this metering device is as follows: in the position shown in FIG. 3, the piston has been pushed down almost completely, i.e. almost the entire metering volume has been expelled. After reaching the lower position, the actuating rod 10 is raised with the tripod 14, so that the lower surfaces of the legs are above the outer circumference of the shaft 3. The shaft 3 is then turned through 180 ° and the piston is now in its uppermost position. In this process, the metering volume is filled at the same time. Then the actuating rod 10 lowers and the piston is thereby pressed into its lowest position. The product then passes through the shut-off valve 8 into the filling mouthpiece 9 and from there into the container intended for it.
  • the storage container 1 can be sealed very easily, so that a completely aseptic filling can be achieved with relatively light means.
  • a high filling frequency can be achieved, since the metering bores fill quickly with each metering stroke, a rotation can be carried out quickly and the actuating rod with the tripod and the piston represent a small mass, which can be easily accelerated without great effort.
  • more than four bores or dosing units can be arranged per device. to achieve a higher waste volume. If solids are to be added to the liquid or pasty mass, it is very easy to provide this. When the piston is knocked down, suction is created and the desired amount of solid particles can then be entered before rotating through 180 °.
  • the supply of solid substances can be carried out easily if the actuating frame and rod consist of tubes through which the solid substances can be passed into the metering volume. Of course, it is also possible to provide a suitable separate line for this. Moreover, it is set festzu ⁇ that the pressure exerted on the product is very low ', and thereby a more gentle treatment is possible. As a result of the individual calibration, ie the calibration of each individual dosing unit, a very precise dosing volume can be set. Finally, the entire dosing device is easy to arrange. The dosing device is particularly suitable for liquid and pasty products, but it is also possible to

  • the shaft 28 has two cylindrical bores 29, the outer shape following the two bores for space-saving reasons, so that the outline of the shaft at the location of the two bores resembles an eight.
  • the bores have the same securing means, ie securing ring or pins, as in the previous example, and the double-acting piston 6 is also the same as in the previous example.
  • the shaft is not sealed off from the outlet, so that the liquid 23 to be filled reaches the shut-off valve 30, so that the shaft rotates completely in the storage liquid.
  • the shut-off valve at the end of the outlet is designed in a known manner as a spring-loaded valve.

Abstract

Le dispositif de dosage comporte un réservoir de stockage (1) dans lequel se trouve, au-dessous de la hauteur de remplissage du produit (23), un arbre (3). Ce dernier possède au moins un alésage (5) dans lequel un piston (6) agissant des deux côtés est enfoncé par une bielle d'actionnement (10) réglable en longueur et entraînée, ce qui permet d'obtenir le volume de dosage souhaité. Le produit arrive au réservoir par une vanne d'arrêt (8). Lors du fonctionnement de ce dispositif de dosage, la bielle d'actionnement (10) est levée dans la position la plus basse du piston, grâce à quoi l'alésage se remplit de produit et l'arbre est tourné de 180° au moyen d'un électro-réducteur (4), après quoi le piston, dans sa course descendante, expulse le volume contenu dans l'alésage. Un tel dispositif de dosage permet une fréquence de soutirage élevée, un réglage simple et précis du volume des différentes unités doseuses, un soutirage des meilleurs et des plus aseptiques et un nettoyage aisé.
