Definitions

  • the subject of the present invention is a method and a device for monitoring and controlling the chain filling of containers with a determined weight of product having a variable density.
  • the device comprises means for controlling the transfer of the product from the volumetric dispenser to the container first at high speed on the first part of the second path of the carousel, then at reduced speed on the second part of the second path of the carousel
  • the device comprises means for acting on the control member as a function of the stop point for filling the container on the second part of the second path of the carousel.
  • Figure 1 are shown the different phases of the path of a container on a chain filling installation comprising a rotary carousel 3 equipped with several filling stations.
  • 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, which is driven in a rotational movement.
  • a distribution star 2 which introduces it at point 6 onto one of the filling stations of the carousel 3, which is driven in a rotational movement.
  • the container is tared, by resetting the balance to zero for example, while the filling of the volumetric metering device started at point 10 is completed.
  • part of the volume of product contained in the volumetric dispenser is transferred with a rapid flow from the dispenser to the container.
  • the transfer continues with a slower flow until the container contains the desired weight of product.
  • the container is weighed continuously.
  • a calculation and storage unit a microprocessor for example, continuously compares the weight of the product contained in the container with the desired weight and, when this desired weight is reached, orders the filling of the container to stop.
  • the filled container then leaves the carousel 3 or tangentially to the carousel 3, on a conveying means 25 or else in a preferred direction, parallel to a conveying means 1 for example, via a distribution star 4 on a conveying means 5.
  • FIG. 2 shows a schematic sectional view of an exemplary embodiment of a filling station.
  • 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 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 calculation and storage.
  • the plug 18 When a filling station is located between points 10 and 7 of the path shown in Figure 1, the plug 18 is positioned so that the recess 15 faces the conduits 24 and 26 of the body 19 and the feed hopper 12 and the volumetric metering device 37 are in communication (case of FIG. 2). When a filling station is located between point 7 and the filling stop point located between points 8 and 9 of the path shown in Figure 1 the plug 18 is positioned so that the conduit 17 is facing the conduits 26 and 30 of the body 19 and the volumetric dispenser 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. 4 comprises a rising ramp with two: successive inclinations: ramp 340 between points 10 and 6, 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 10 (the numbering of these points corresponds to that of FIG. 1).
  • the upward path corresponds to the filling of the volumetric dispenser 37.
  • the downward path corresponds in part to the transfer of the product from the volumetric doser 37 into the container 39.
  • the cam 34 is fixed relative to the rotary carousel 3 on which the filling stations are installed. It controls the operation of each of them by guiding a roller 32 secured to the rod 33 of the piston 28, by the interposition of elastic means 40 fixed on the one hand to the end of the rod 33, on the other hand to a fixed point 41 secured to the carousel.
  • the elastic means 40 work in compression and keep the roller 32 in contact with the cam 34 which allows the guiding the roller 32 by the cam on the downward ramp thereof. They have another function: when the container 39 is filled with the desired weight of product, the calculation and storage unit controls the closing of the dispensing orifice of the volumetric dispenser. The stroke of the piston 28 is thereby interrupted.
  • the roller 32 was guided along the descending ramp by rigid means, a rail parallel to the cam 34 coming into contact with the upper part of the roller, for example, damage would ensue.
  • the elastic means 40 the compression force of which has been calculated so that it is greater than the resistance encountered by the piston of the volumetric dispenser when it drives the product into the container, but less than the resistant force exerted on the elastic means by the piston rod when it is blocked, absorb the excess travel of the piston.
  • the roller 32 leaves the contact of the descending ramp of the cam at the point of filling the container and resumes contact with the rising ramp of the cam at a point situated in the same horizontal plane as the point where the filling of the container is stopped.
  • the guiding of the roller 32 by the cam 34 with the interposition of elastic means also constitutes security for the filling installation: the accidental blocking of a piston does not cause any unfortunate consequence of the fact that the roller can escape from drug.
  • the filling of the volumetric metering device 37 can be modified so that the point of stopping the filling of the container 39 takes place between points 8 and 9, that is to say on the descending ramp 343, when the filling rate is slow.
  • FIG. 4 is shown a device, allowing the modification of the volume admitted into the volumetric metering device, constituted by a part of an ascending ramp 341 of the cam 34 with adjustable inclination, and a gear motor 25 actuating an endless screw 16.
  • the inclination of the ramp part 341 is adjusted so that the point of stopping the filling of the containers takes place between points 8 and 9.
  • the calculation and storage unit records the coordinates of the stop point for filling each container and check that it is on the ramp part 343. If for some reason or other a drift occurs and the stop point for filling the containers closer to point 8 or point 9 beyond determined set values, the calculation and storage unit would command a modification of the inclination of the ramp part 341, up or down depending on the direction drift.
  • FIG. 5 represents an example of an embodiment of elastic means interposed between the cam 34 and the rod 33 of the piston of each volumetric metering device 37.
  • the elastic means used in this example consist of a pneumatic cylinder comprising a cylinder 44 integral with the carousel 3 , a piston 43 sliding in the cylinder 44, a rod 42 fixed to the piston 43 at one end and secured to the roller 42 at the other end.
  • the pneumatic cylinder of each filling station is connected to the cylinder of all the other filling stations and has a buffer volume 46 by a pipe 45.
  • Figure 6 shows the sectional view of another embodiment of elastic means interposed between the cam 34 and the rod 33 of the piston.de each volumetric metering device.
  • the piston 28 of the volumetric metering device 37 is surmounted by a cylindrical part 47 having a bore intended to guide the end of the rod 33.
  • the rod 33 has a vertical slot 48. It enters the bore of the cylindrical part 47 where it can slide vertically between two extreme positions defined by the light 48, light which passes a horizontal pin 5 0 jack at both ends in the cylindrical portion 47.
  • on the rod 33 is fixed in addition, by a pin 51, a ring 49 having a shoulder.
  • a spring 52 working in compression is disposed between the ring 49 and the piston 28 along the axis of the rod 33.
