    FILLING DEVICE AND METHOD FOR AUTOMATIC HORIZONTAL MACHINE FORMER AND FILLER OF FLEXIBLE CONTAINERS
    Technical field
    The present invention concerns a filling device for automatic horizontal forming machine and flexible packaging liner, including means for preventing splashing from a filling nozzle at the time of closing a filling valve that opens and closes a duct of supply of a product capable of flowing used to fill the containers. The present invention also concerns a filling method for an automatic horizontal forming machine and flexible packaging liner equipped with such a filling device.
    Background of the invention
    Automatic horizontal forming and packaging machine machines are known which essentially comprise a belt supply unit that supplies a heat-sealable flexible sheet band from a coil, a packaging forming unit that forms individual flexible packages from said sheet band flexible, a filling unit that fills individual flexible containers with one or more products, and a closing unit that closes filled flexible containers and delivers them to an outgoing conveyor.
    In this type of machines, said filling unit includes one or more filling devices, each of which comprises a supply conduit connected to an inlet of a filling valve for supplying a flowable product, and a nozzle of filling connected to an outlet of the filling valve to guide said product capable of flowing into an opening of a container, where a control device controls the opening and closing of the filling valve according to the movements of a conveyor device that positions successive flexible packages in relation to said filling nozzle.
    A problem with prior art filling devices is that, during the closing action of the filling valve, the passage area of the valve is gradually reduced while the pressure in the supply line remains constant, and this produces an acceleration of the product capable of flowing through the filling valve that causes splashing from the outlet of the filling nozzle just before the shut-off valve
    reach a completely closed position. These splashes are an inconvenience since they can dirty the outer surfaces of the flexible containers and contaminate the environment of the filling device, forcing frequent cleaning.
    JP 2010222023 A describes a filling device comprising a four-way rotary valve, a supply conduit connected to an upper opening of the four-way valve for supplying a flowable product, a filling piston pump connected to a side opening of the four-way valve, a suction piston pump connected to another side opening of the four-way valve, and a filling nozzle connected to a bottom opening of the four-way valve. The suction piston pump is used to suction the remaining flowable product content in the filling nozzle in order to avoid splashing and dripping after the four-way valve has closed the passage to the filling nozzle. However, this device is mechanically complex and economically expensive.
    Exhibition of the invention
    The object of the present invention is to solve or mitigate the foregoing and other inconveniences by providing a filling device for automatic horizontal forming machine and flexible packaging liner, comprising a filling valve, a supply conduit connected to an inlet of said filling valve for supplying a flowable product, a filling nozzle connected to an outlet of the filling valve to guide said flowable product towards an opening of a flexible container, and a control device configured to open and close the filling valve of according to a conveyor device that positions successive flexible packages in relation to said filling nozzle to perform successive filling cycles.
    The filling device further comprises an auxiliary valve interposed in said supply line upstream of the filling valve. This auxiliary valve is controlled by said control device to close the passage of the product capable of flowing into the supply line upstream of the filling valve before the closing of the filling valve at the end of a cycle of filling is completed. fill.
    Thus, from the moment the auxiliary valve has closed the passage of the product capable of flowing in the supply line upstream of the filling valve, the pressure decreases or ceases in the section of the supply conduit between the auxiliary valve and the filling valve and consequently the acceleration of the product capable of flowing through the filling valve does not occur and splashes are prevented from
    the outlet of the filling nozzle during the closing of the filling valve from a fully or partially open position to a completely closed position.
    The control device is also configured to open the auxiliary valve and allow the passage of the product capable of flowing through it, and thereby restore a predetermined working pressure in said section of the supply line between the auxiliary valve and the valve of filling, before the opening of the filling valve has begun to fill a new container.
    The opening and closing movements of the filling valve and the auxiliary valve are governed by respective actuating devices controlled by the control device. Preferably, the auxiliary valve actuation device provides a closing time from a fully open position to a completely closed position shorter than a closing time provided by the filling valve actuation device from a fully open position at a fully open position. fully closed position. This offers the possibility for the control device to simultaneously issue the opening and closing orders for the filling valve and for the auxiliary valve.
    As an auxiliary valve, a membrane valve may be suitable, for example a pneumatically operated membrane valve, and as a filling valve a seat valve, such as a motor-driven seat valve, for example, a motor, may be appropriate. electric.
    The method of the present invention comprises performing the following steps for each filling cycle using the filling device described above. First, open the filling valve to whose inlet the supply line that supplies the product that is capable of flowing is connected to the inlet, and whose outlet is connected to the filling nozzle that guides the product that can flow into the opening of a flexible container Then, after a predetermined time, close the filling valve by means of the control device at the end of the filling cycle, with the intention of closing the auxiliary valve interposed in the supply line upstream of the control via the control device. filling valve to interrupt the passage of the product capable of flowing into the supply line upstream of the filling valve before the closing of the filling valve is completed at the end of the filling cycle.
    BRIEF DESCRIPTION OF THE DRAWINGS The above advantages and characteristics will be more fully understood from the following detailed description of an exemplary embodiment, which is provided merely for illustrative purposes and not limitation, with reference to the accompanying drawings, in the that:
    Fig. 1 (single figure) is a schematic side view of a filling device for automatic horizontal forming machine and flexible packaging liner according to an embodiment of the present invention.
    Detailed description of an embodiment example
    Fig. 1 shows a filling valve 1 supported on a structural element 5 of an automatic horizontal forming machine and flexible packaging liner. This filling valve 1 has an upper inlet to which a supply conduit 2 is connected and a lower outlet to which a filling nozzle 3 is connected. Through the supply conduit 2 a flowable product is supplied, typically a liquid or a paste, at a predetermined working pressure. Upstream of the filling valve 1 there is an auxiliary valve 4 interposed in the supply line 2.
    The automatic horizontal flexible forming and filling machine comprises a conveyor device, which can be of any known type and is not part of the present invention, which has for example a pair of tweezers 6 configured to support a plurality of flexible packages E and a step-by-step translation means for successively positioning each of the flexible packages E supported by the tweezers 6 with an upper opening E1 thereof open below the filling nozzle 3. The filling nozzle 3 is configured to guide the product liable to flow into said opening E1 of flexible container E.
    The filling device is governed by a control device 10 configured to open and close the filling valve 1 in accordance with the movements of the conveyor device. The control device 10 also controls the auxiliary valve 4 so that, at the end of the filling of each flexible container E, the control valve 4 closes the passage of the product capable of flowing into the supply line 2 upstream of the valve filling 1 before the closing of the filling valve 1 is completed. This substantially reduces or eliminates the pressure of the product that can flow into the section of the supply line 2 between the auxiliary valve 4 and the filling valve 1 and prevents splashing from the filling nozzle 3 at the time of filling of the filling valve 1.
    In the embodiment shown in Fig. 1, the auxiliary valve 4 is a membrane valve provided with a pneumatic drive 7 and the filling valve 1 is a seat valve driven by an electric motor 8. A pneumatic supply tube 11 provides power to the pneumatic actuator 7 of the auxiliary valve 4. The control device 10
    5 is connected by a signal line 12 to a control valve 9 interposed in said pneumatic supply tube 11 and by another control line 13 to the electric motor 8 of the filling valve 1.
    Typically, the pneumatic drive 7 of the auxiliary valve 4 provides a closing time from a fully open position to a completely closed position of
    10 the auxiliary valve 4 shorter than a closing time provided by the electric motor 8 of the filling valve 1 from a fully open position to a completely closed position of the filling valve 1.
    The scope of the present invention is defined in the appended claims.
