Definitions

  • the object of the present invention is a method and an installation for filling containers.
  • volumetric dosers of the type comprising a timer which controls the opening and closing of the orifice of a reservoir of product to be packaged or of the type comprising a cylinder-piston assembly in which the piston stroke defines the volume to be introduced into the container.
  • These dosers are adjusted to deliver a given volume of product at a given temperature. If the temperature of the product introduced into it varies over the course of a day, over a few days etc., the quantity of product introduced into the containers will vary.
  • a balance only the weight making it possible to define exactly a quantity of product which whatever the temperature.
  • this device has some disadvantages in practice.
  • the transfer of the container from the conveyor belt to the balance then from the balance to the conveyor belt as well as the weighing of the container which, to be precise, must last a minimum time does not allow a very rapid filling rate.
  • this device it is not intended to tare the containers.
  • the weight of the containers even manufactured in series, can vary significantly. This is particularly the case for glass containers. Therefore it is not possible to determine the exact weight of the contents of the weighed containers.
  • Document US-A-2 961 013 describes an installation for filling receptacles by means of volumetric devices each comprising a piston moving in a cylinder, the movements of the pistons being caused by a movable cam whose position determines the volume distributed to each hit of boost.
  • the position of the cam is controlled as a function of various parameters, but at no time is it intended to check the weight of product dispensed so that this weight can vary depending on the density of the product dispensed.
  • Document EP-A-52 546 describes a weight metering device in which the product to be dispensed is placed in a hopper and flows out when a filling spout is opened. Such a device is not suitable for filling containers at a high rate with a product of high viscosity.
  • An object of the present invention is to provide a method and an installation for filling containers which make it possible to achieve a high rate while retaining high precision whatever the viscosity of the product to be dispensed.
  • a container filling installation comprising: a rotary carousel, means for introducing containers one by one onto a plurality of filling stations each comprising a volumetric metering device of the type comprising a piston-cylinder assembly in which the stroke of the piston defines the volume of product transferred, means for filling the volumetric dispenser with product and then emptying the latter into a container, the volume transferred being determined by a control member (such an installation is known from the document US- A-2 961 013), characterized in that at least one filling station includes a scale associated with a calculation and storage device for storing the weight of an empty container introduced on the scale, the weight of the full container given by each balance to calculate the net weight of the product introduced into the container, and means for acting on the control member in order to modify the volume e of product to be introduced into the containers on the carousel upstream of the weighed container.
  • Figure 1 are shown the different phases of the path of a container placed on one of the filling stations equipped with a balance of a chain filling installation comprising a rotating carousel 3.
  • the container is conveyed by a conveying means 1 to a distribution star 2 which introduces it at point 6 onto one of the filling stations of the carousel 3 equipped with a scale.
  • Carousel 3 is rotated. Between point 6 and point 7 the empty container is weighed and its weight is stored in memory while the filling of the volumetric metering unit of the filling station, started at point 40, is completed.
  • the volume of product contained in the volumetric dispenser is transferred with a rapid flow rate (7-8) then with a slower flow rate (8-9) from the dispenser to the container.
  • the container is weighed continuously between its entry into the carousel and its exit from the carousel. Between point 9 and point 10 the balance stabilizes and determines the weight of the full container.
  • a calculation and control unit a microprocessor for example, calculates from the weight of the full container and the weight of the empty container previously stored the exact weight of the product introduced into the container, compares this weight with a set value and optionally orders the modification of the dosage which will intervene for the containers appearing at a later stage.
  • the advantage of the mobility of the balance (s) installed on the carousel is to allow a weighing time long enough to be precise, without slowing down the filling rate.
  • the container leaves the carousel 3 or else at point 10, tangentially to the carousel 3, on a conveying means 25, or else at point 40, in a preferred direction, parallel to the conveying means 1 for example, by the through a distribution star 4.
  • FIG. 2 shows a schematic sectional view of an exemplary embodiment of a filling station equipped with a balance.
  • Each filling station is located on the rotary carousel 3 and comprises: an electronic balance 36; means 38 for centering a container 39; a product feed hopper 22 to be packaged 12; a volumetric metering device 37 comprising a piston 28 provided with sealing means 29, a cylinder 13 in which the piston 28 slides, a rod 33 actuating the piston 28; a distributor 14 comprising a body 19 and a cylindrical plug 18 capable of pivoting in the body 19.
  • the body 19 has a horizontal bore of axis 27; a vertical duct 24 located in its upper part and opening on the one hand into the feed hopper 12 and on the other hand into the bore of axis 27; a vertical duct 26 located in its upper part and opening on the one hand into the volumetric metering device 37 and on the other hand into the bore of axis 27; a vertical bore of the same axis as the conduit 26, surmounting the latter and receiving the cylinder 13 of the volumetric metering device 37; a vertical duct 30 located in its lower part and opening on the one hand into the bore of axis 27 and on the other hand above the container 39.
  • the cylindrical plug 18 occupies the vertical bore of axis 27 of the body 19 in which it can pivot. It comprises a recess 15 which, in a determined position of the plug 18 relative to the body 19, connects the conduits 24 and 26 of the body 19; a cylindrical conduit 17, without communication with the recess 15, which, in another determined position of the plug 18 relative to the body 19, connects the conduits 26 and 30 of the body 19; a control lever 20 for pivoting the plug 18 inside the body 19. Electrical, pneumatic or equivalent means, not shown in the figure, act on the control lever 20 on the instructions communicated to them by the member of calculation and order.
  • plug 18 When a filling station is located between points 10 and 7 of the path shown in FIG. 1, the plug 18 is positioned so that the recess 15 faces the conduits 24 and 26 of the body 19 and the hopper of supply 12 and the volumetric dispenser 37 are in communication (case of FIG. 2). When a filling station is located between point 7 and point 9 of the path shown in FIG. 1, plug 18 is positioned so that the conduit 17 faces the conduits 26 and 30 of the body 19 and the volumetric metering device 37 and the container 39 are in communication.
  • FIG. 4 represents a schematic developed view of a cam controlling the operation of two filling stations. It must be understood that in reality such a cam is not located in a plane but is wound on a cylinder with the same center as the carousel and that it controls a number of filling stations, variable depending on the case, but well above 2.
  • the cam 34 shown in FIG. 2 comprises a rising ramp with two successive inclinations: ramp 340 between points 40 and 6, adjustable ramp 341, between points 6 and 7; a downward ramp with two inclinations: ramp 342 between points 7 and 8, ramp 343 between points 8 and 9; a horizontal part 344 between points 9 and 40.
  • a cam follower 35 parallel to cam 34, is arranged above the descending ramp of cam 34, between points 7 and 9. (The numbering of these points corresponds to that of figure 1).
  • the rising ramp corresponds to the filling of the volumetric metering device 37, which in this embodiment is a metering cylinder.
  • the downward ramp with two inclinations corresponds to the transfer of the product at two flow speeds, from the volumetric dispenser 37 into the container 39.
  • the cam 34 and the cam follower 35 are fixed relative to the rotary carousel 3 on which the filling stations are installed.
  • the cam 34 guides only the roller 32 secured to the rod 33 of the piston 28 between point 40 and point 7. Between point 7 and point 9, that is to say on the descending ramp of the cam 34, the cam 34 cooperates with the cam follower 35 to guide the roller 32.
  • the cam 34 has a rising ramp portion 341 whose inclination, which is variable, is adjusted by the stroke of an endless screw 16 driven by a geared motor 25. If the calculation and control member finds a difference between the weight of product introduced into the container and the set value, it controls the modification of the inclination of the ramp part 341 up or down depending on the direction of the drift. The resulting change in the volume admitted into the volumetric dispenser occurs naturally for containers that appear at a later stage.
