Definitions

  • the object of the present invention is a method and a device for monitoring and controlling the filling of containers successively engaged in a chain filling installation.
  • volumetric metering devices of the type comprising a timer which controls the opening and closing of the orifice of a reservoir of product to be conditioned or of the type comprising a cylinder-piston assembly in which the piston stroke defines the volume to be introduced into the container.
  • These dispensers are adjusted to deliver a given volume of product, to. 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 While it allows in theory to solve the problem posed, this device has some drawbacks in practice. On the one hand the transfer of the container from the conveyor belt to the scale 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. On the other hand, on this device, it is not intended to tare the containers. However, depending on the material of which they are made, the weight of the containers, even manufactured in series, can vary appreciably. 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.
  • the complete path on the filling installation of a container placed on a scale associated with one of the filling stations successively comprises a weighing phase of the empty container, a filling phase and a phase weighing the full container, calculation means determining, after this last phase, the exact weight of the product introduced.
  • the dosage of the product is adjusted by a timer or by a cam.
  • control member is either a timer defining the duration of filling on each station, or a cam acting on the stroke of the piston of a metering cylinder and at least part of which can be moved to modify the stroke of the piston and consequently the volume of the metering cylinder.
  • 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 in point 6 on one of the. carousel 3 filling stations 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 (7-8) then with a slower flow (8-9) from the doser 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 in memory the exact weight of the product introduced into the container, compares this weight with a set value and orders possibly the modification of the dosage which will intervene for the containers presenting themselves 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 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 hopper for supplying the product 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 situated 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. '
  • the 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 1a and the hopper of power supply 12 and the volumetric metering device: 37 are in communication (case of ' Figure 2). When a filling station is located between point 7 and point 9 of the path shown in FIG. 1, the 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 downward 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 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.
