- the carriage 13 is connected to a second actuator 15 making it possible in particular to move the filling spout 11 substantially vertically between a high position, or disengaged position, in which the filling cannula 11.2 is outside the bottle (FIG. 1). and a first low position, or engaged position, in which the filling cannula 11.2 is engaged inside the bottle B, a free end of said filling cannula then extending near a bottom of said bottle B (figure 2).
- the first actuator 17 can for example be a linear electromechanical actuator, a servomotor or a stepping motor driving in rotation an endless screw cooperating with a nut fixed to the valve to have a substantially vertical axis.
- the second actuator 15 can for example be a linear electromechanical actuator, a servomotor or a stepping motor rotating a worm screw cooperating with a nut fixed to the carriage 13 to have a substantially vertical axis.
- a programmable control unit UC (not shown here) is connected to the strain gauge and is arranged to control the first actuator 17 and the second actuator 15.
- the filling device 1 further comprises an annular-shaped cleaning manifold 16 which is fixed to the frame 5 so as to extend coaxially with the tubular body 3 of the turret 2, and therefore also with respect to the first, second and third platforms 8.1, 8.2, 8.3.
- the collector of cleaning 13 is arranged slightly below the trays 9 intended to receive the bottles B and comprises, facing each of the filling nozzles 11, an inlet orifice 16.1 extending projecting and arranged to receive the free end of the filling cannula 11.2.
- each of the plates 9 comprises, opposite each of the filling nozzles, a hole 9.1 arranged to allow the filling cannula 11.2 to pass through said plate 9 to join the inlet orifice 16.1 of the cleaning manifold 16.
- the carriage 13 controlled by the second actuator 15 also allows the filling spout 11 to be moved substantially vertically between the engagement position and a second low position, or cleaning position, in which the free end of the filling cannula 11.2 is engaged in one of the inlet openings 16.1 of the cleaning manifold 16 (FIG. 3).
- the engagement position is thus between the release position and the cleaning position.
- the duct 12 connecting the supply chamber 11.1 of the filling spout 11 to the distribution chamber delimited by the cylindrical body 6 is arranged to ensure, whatever the position of the filling spout 11, the supply of product. liquid from said filling spout 11.
- the duct 12 here comprises a first section 12.1 and a second section 12.2 rigid connected to each other by a first articulated connector 12.3, the first section 12.1 and the second section 12.2 being respectively connected to an outlet orifice 6.2 of the distribution chamber and to an inlet orifice of the supply chamber 11.1 of the spout filling 11 by a second and a third articulated connector 12.3.
- the bottle B intended to be filled with liquid product is brought onto the plate 9 so that the upper opening B2 of the bottle B is opposite the filling cannula 11.2 of the plunger spout 11.
- the plunger spout 11 is then in the disengaged position and the valve mounted inside the supply chamber 11.1 of the filling spout 11 is in the closed position (FIG. 1).
- control unit UC controls the second actuator 15 to bring the filling spout 11 into the engagement position.
- the free end of the filling cannula 11.2 then extends into the bottle B, near the bottom of the bottle B
- the control unit UC then controls the first actuator 17 to bring the valve mounted inside the supply chamber 11.1 of the filling spout 11 to the open position in which the liquid product flows from the chamber d 11.1 feed of the tubular body to the filling cannula 11.2 to form a jet of liquid product escaping substantially horizontally from the free end of the filling cannula 11.2.
- the second actuator 15 is again controlled by the control unit UC to move the filling spout 11 from the engagement position towards the disengaged position, the liquid product continuing to flow into the bottle B.
- the movement of the filling spout is synchronized with the quantity of liquid contained in the bottle B which is measured by the strain gauge.
- the filling spout 11 is permanently above the level of liquid product contained in the bottle or that it is slightly immersed in the liquid product throughout the filling, in particular when the latter is foamy.
- the first actuator 17 is controlled by the control unit UC to bring the valve mounted inside the supply chamber. 11.1 of the filling spout 11 in the closed position and thus stop the filling of the bottle B.
- the filling spout 11 then continues to rise and reaches the disengaged position.
- the bottle B can then be removed from the plate 9 and for example receive a stopper on the upper opening B2 of the bottle B.
- the movement of the filling spout 11 is independent of the angular position of the turret 2. Furthermore, it will be noted that the filling speed of the bottle B is independent of the rotational speed of the turret 2.
- the filling cannula 11.2 of the filling spout 11 will probably bear, during its descent, on a wall of said bottle B, which will generate abnormal mechanical forces which may be detected by the strain gauge 10.
- the control unit UC can then, for example, be programmed to trigger an audible and / or visual alarm, but also to stop the descent of the filling spout, or even to control its ascent.
- the control unit UC controls the second actuator 15 so as to move the filler spout 11 to the cleaning position (FIG. 3).
- the movement of the filling spout 11 towards the cleaning position can of course be conditioned by a detection of the non-presence of the bottle B on the plate 9 by the strain gauge 10.
- the control unit UC controls the first actuator 17 to allow the flow of liquid product through the filling spout to form a substantially horizontal jet inside the cleaning manifold 16.
- the liquid product introduced into the cleaning collector 16 then flows into an evacuation duct 16.3 of said cleaning collector 16.
- control unit UC controls the first actuator 17 to stop the flow of liquid product and then controls the second actuator 15 to raise the filling spout 11 in the disengaged position.
- the liquid product is replaced, during cleaning of the filling spout by a cleaning liquid making it possible to ensure cleaning of the various elements of the filling device 1 through which the liquid product passes without degrading them.
- the control unit UC can thus be programmed to automatically carry out the cleaning of the filling spouts 11, that is to say without any physical intervention by the operator, which represents significant time savings, thus improving the productivity of the installation and allows sanitary hygiene compatible with filling with food, pharmaceutical or cosmetic products.
- the plunger 11 is fixed and it is the plate 9 on which the bottle B is placed which is connected to a vertically movable mounted carriage.
- the device here does not have the fixed cleaning manifold 16 and the strain gauge. In this case, the incorrect positioning of the bottle B can for example be detected directly by reading the current flowing through the second actuator 15.
- the filling of the bottle B is carried out by a volumetric dosing system (the quantity of liquid product introduced into the bottle B is determined by measuring the weight of said bottle B by through the strain gauge 10), it can also be achieved by a flow metering dosing system.
- the valve of the filling spout 11 can for example be equipped with a flowmeter connected to the control unit UC such that the control unit UC controls the first actuator 17 from the measurements of the flowmeter.
- the filling device 1 is of the rotary type, other types can be envisaged and in particular a filling device of the translational type.
- the numbers of trays 9, of carriages 13 and of filling spouts 11 may of course be different from that of the filling device 1 described and shown here.
- the arrangement of the outlet orifices 6.2 can of course be different from that of the filling device 1 illustrated in FIGS. 1 to 3.
- the outlet orifice 6.2 can be axial.
- An upper surface of the plate 9 can be shaped to match the lower surface B1 of the bottle B and improve the positioning accuracy of said bottle B on the plate 9.
- the plate 9 can be replaced by a plate arranged to receive a neck of said bottle B and thus maintain the bottle B under the filling spout 11.
