Definitions

  • the present invention relates to container filling installations, and more particularly, to a method and a device for dosing container filling material in a filling machine with metering by weight.
  • Weight dosing is becoming more and more necessary in filling installations with liquid or divided materials, for example in the food or pharmaceutical industries, because of obtaining more precise and more reliable results compared to installations with volumetric dosing .
  • This technique requires the arrangement, for each filling head, of a weighing scale associated with detection means for controlling the filling head as a function of the weight of filling material actually delivered.
  • detection means for controlling the filling head as a function of the weight of filling material actually delivered.
  • This all-or-nothing control technique gives all satisfaction with regard to the robustness of the reliability of use but has the disadvantage of having to take into account and also correct fluctuating parameters of the filling installations, such as for example those relating to the taring of empty containers or the weight of the column of material delivered between the outlet of the filling head and the container, requiring the use of means for correcting proximity switches as described for example in French patent application No. 78/1787 in the name of the applicant.
  • the object of the present invention is precisely to propose a method and a device for dosing container filling material in filling machines with weight dosing, overcoming the above drawbacks, offering, while retaining high reliability in use, a great flexibility of use by integrating programmable logic components and making it possible to modulate the operating conditions of the installation, either by injecting image data of specific parameters, or automatically during operation
  • the process according to the present invention implemented in a filling machine comprising at least one filling / weighing station with a filling head, a weighing balance with parallelogram equipment, detection means being associated with the provi- t if weighing for controlling the filling head, is mechanically coupled to a movable member of the crew of the balance a force sensor and to transmit continuously the output signal of the sensor unit logic-programmable with memory providing a control signal to the filling head when the detected weight value reaches a value deducted and corrected from the recorded nominal value.
  • the metering device for such a filling machine comprising at least one filling station with a controllable filling head and a weighing scale with parallelogram equipment, detection means being associated with the weighing balance to supply a control signal to the filling head, comprises a force sensor mechanically coupled to a mobile element of the equipment of the balance and connected to a first entry of a programmable logic unit with memory comprising a second control and storage input, the output of which is connected to the filling head.
  • the force sensor being of the sensitive blade and strain gauge type
  • the mechanical coupling between the sensor and the moving element or beam of the balance equipment is carried out by a cable traction.
  • the Applicant has found that the output signal from a transducer operating in compression was almost unusable in a filling machine, while the tensile stress, more particularly by a flexible cable, makes it possible to decrease with a factor of 10 the effects of vibrations on the sensitive sensor plate.
  • FIG. 2 there is a multi-station filling carousel 1 supplied with containers to be filled by an upstream transfer carousel 2 picking up the containers 3 on a linear conveyor 4, the containers filled in the filling carousel 1 being withdrawn therefrom and recirculated on the linear conveyor 4 by an output transfer carousel 5.
  • the filling carousel 1 is provided with a number of weighing stations (typically 12 or 24) of the type shown in FIG. 1.
  • the balance 8 consists of a supporting column 9, mounted on a frame 10 secured to the hollow shaft 11 of the carousel, a floating column 11, and a lower beam 12, the parallelogram being completed by a upper cross member 13, these various elements being articulated with respect to each other by means of ball bearings such than that shown in 14.
  • the balance 8 has a particularly compact configuration, with the average height of the columns greater than or double the length of the crosspieces.
  • the plate 7 is connected to the floating column 11 by a hollow tubular upright 15.
  • the post 15 for adjusting the leveling of the scale plate 7 with the plate 16 of the carousel, has its lower end 'higher on a cam surface 17 scalable controllable by a shaft 18 , the upright 15 being fixed to the floating column 11, once leveled, by clamping plates 19.
  • the various scales of the carousel 1 are traditionally housed in a casing comprising an upper cover 20 and an external peripheral skirt 21.
  • the upright 15 of the plate 7 is associated with a cylinder labyrinth system 22, as shown in FIG.
  • the plate 7 is traditionally equipped with open flanges 23 for centering the containers, located for the bottles at the neck of these bottles and inducing the problems of parasitic couplings mentioned above.
  • the balance equipment 8 can be completed by a counterweight 24, mounted on an extension of the beam 12, although this counterweight induces inertial torque problems requiring mass compensation on the other side of the balance, such a counterweight being not necessary with the force sensor according to the present invention.
  • the force transducer 25 comprising a sensitive blade 26 with strain gauge, is mounted on a stirrup 27, substantially in the extension of the upper cross member 13, the stirrup 27 being fixed by the inner ends of its lateral branches to the column support 9.
  • this support column 9 is also fixed to the frame 10 with the interposition of elastic elastomer elements 28, for example of the so-called "Silent-Block" type.
  • the sensitive blade 26 of the sensor 25 is mechanically coupled to the outer end of the beam 12 by a cable 28 carrying normally a traction on the sensitive blade in a direction perpendicular to the plane thereof.
  • the cable 28 passes through the orifice of the sensitive blade 26 and a helical spring 29, at the upper end of which is connected the adjacent end of the cable 28, the spring 29 carrying by a cup profiled on the blade 26.
  • the spring 29 is of the high stiffness type and designed to start to crush under the application of a compressive force of the order of 20 kg, that is to say much greater at the normal weight of the filled containers to be weighed by the balance.
  • the sensor 25 is chosen with a sensitive blade of the 20 kg class. To avoid any accidental damage to the sensitive blade, the downward angular movement of the beam 12 is limited by an adjustable stop 30.
  • the output of the force sensor 25 is routed by a line 31 to a measurement input 32 of a programmable logic unit with microprocessor 33, housed in a support with damper below the crew, 8.
  • the balance unit logical memory 33 comprises at least one second inlet 34, for injecting data memory determined and the inclusion of no determined program.
  • a calculation output 35 of the logic unit 33 is connected by a line 36, to the filling head 6, to selectively control the opening and closing thereof according to conditions developed by the logic unit 33, typically when the weight value measured by the sensor, converted to digital, reaches an internal displayed value.
  • the dosage control method according to the present invention will now be explained in more detail with reference to the layout diagram in FIG. 2.
  • the data specific to this cycle in particular the weight values desired according to the type of products to be filled and the dimensions of the containers, are injected through the inlet 34 into the logic units 33 of the balans these different filling stations of the carousel 1.
  • the desired weight of the filling material of the container is 1000 grams.
  • a first passage of containers supplied by the linear conveyor 4, allows, for successive filling stations, the associated sensors 25 to transmit to the corresponding logic units 33, during the first angular transfer phase AB from the loading area A, ( angle AB of the order of 15 to 20 °) -, measurement signals making them take into account the weight of the tare formed by each container, which makes it possible to reset the registers of the logic unit 33 for make it carry out a continuous measurement in net weight during the angular transfer phase BC upstream of the unloading zone D , that is to say before structural elements of the transfer carousel 5 begin to come into contact with the containers.
  • the angle CD is chosen in the range of 10 to 15 °.
  • the logic unit 33 will have supplied, by its output 35, a signal for closing the head 6 when the value detected by the sensor 25 - shifted from the initial taking into account of the taring - will have reached 900 grams, upstream of the angular zone C.
  • the logic unit 33 records the actual weight of the container filled, and, during the angular transfer phase at vacuum DA, performs the comparison with the desired value recorded to correct it, thus taking into account the parameters specific to the filling cycle considered, such as the weight of the material column or the impact force thereof depending on the filling rate , so that the value taken into account in the following cycle to order the head of closing will be different from the exact value desired and from the value initially displayed to provide, from this second cycle, the taring offset being effected each time during the AB transfer, the exact weight required; in this case 1000 grams to ⁇ 5 grams.
  • the method according to the present invention also makes it possible to take into account unwanted quantities of material on the plates 7, originating for example from leaks from previous containers and to actuate, by an outlet 37, an alarm device and / or a display, signaling the malfunction of a head as detected during the comparison phase in the angular transfer phase DA.
