Abstract

The invention relates to a filling machine (1, 1′) for filling packages (2) with fluid products with a continuously circulating transport device (14) for transporting the packages (2) through the filling machine (1, 1′), comprising a plurality of cells (15) for receiving the packages (2), wherein a supply device (13) for supplying packages (2) to be filled is assigned to a supply region (16) of the transport device (14), and an output device (27) for outputting the packages (2) is assigned to an output region (28) of the transport device (14), wherein a filling region (17) is provided between the supply region (16) and the output region (28) in the transport direction (14) of the transport device (14), and a return region (29) of the respective transport device (14) is provided between the output region (28) and the supply region (16), and wherein at least one nozzle (38, 38′) for spraying the cells (15) with a cleaning fluid (40) is associated with the return region (29) of the transport device (14). According to the invention, so that the accumulation of impurities and the contamination of the filled product with microorganisms can be better prevented, a spray wall (39) is arranged on the side of the transport device (14) facing away from the at least one nozzle (38, 38′) and opposite the nozzle (38, 38′) in order to catch and discharge cleaning fluid (40) sprayed from the nozzle (38, 38′) and passing the cells (15).

First claim

1 . A filling machine for filling packages with fluid products, with a continuously circulating transport device for transporting the packages through the filling machine comprising a plurality of cells for receiving the packages, wherein a supply device for supplying packages to be filled is assigned to a supply region of the transport device and a discharge device for discharging the packages is assigned to a discharge region of the transport device, wherein in the transport direction of the transport device a filling region is provided between the supply region and the discharge region and a return region provided between the discharge region and the supply region in each case of the transport device and wherein at least one nozzle for spraying the cells with a cleaning fluid is assigned to the return region of the transport device, and wherein
a splash board for collecting and draining cleaning fluid sprayed by the nozzle and passing the cells is arranged on the side of the transport device facing away from the at least one nozzle and opposite the nozzle, characterized in that the at least one nozzle and the at least one splash board are assigned to a deviation region of the transport device.

2 . The filling machine according to claim 1 ,
characterised in that the at least one nozzle is provided for spraying the cleaning fluid at least partially upwards, preferably largely horizontally, in particular at an angle of between 5° and 20° to the horizontal and/or in that the at least one nozzle for spraying the cleaning fluid is provided at an angle of between 5° and 35°, preferably of between 5° and 20° to the longitudinal extension of the cells.

3 . The filling machine according to claim 1 ,
characterised in that the splash board is formed at least in sections as a splash guard for collecting and draining cleaning fluid and/or in that the side of the splash board facing the nozzle points at least partially, preferably largely downwards and/or is at least partially convexly curved and/or in that a tray for collecting the cleaning fluid, in particular reflected and/or dripping from the splash board is provided under the splash board, in particular under the transport device.

4 . The filling machine according to claim 3 ,
characterised in that the inclination and/or the curvature of the side of the splash board facing the nozzle and the spray direction of the at least one nozzle are matched to one another such that the cleaning fluid is reflected at least substantially vertically, preferably at an angle smaller than 10°, in particular at an angle smaller than 5° to the vertical of the splash board.

5 . The filling machine according to claim 1 ,
characterised in that the cells are open at the base side and/or head side and preferably in that on the inner side of the transport device, preferably in the deviation region of the transport device at least one discharge device is provided penetrating from the base region of the cells at least partially into the cells, preferably guided in an oscillating manner, for ejecting the packages from the cells.

6 . The filling machine according to claim 1 ,
characterised in that the at least one nozzle is provided such that the cleaning fluid is sprayed at least partially from below, preferably from the head side of the cells into the cells and/or in that the at least one nozzle and the at least one splash board are aligned in relation to one another such that the cleaning fluid reflected by the splash board cleans the cells, in particular enters into the cells, at least partially from above, preferably from the base side of the cells.

7 . The filling machine according to claim 1 ,
characterised in that the transport device has a plurality of, preferably three, four, five or six rows of circulating cells, preferably parallel to one another and in that, preferably, at least one nozzle is assigned to each row of cells and/or a common splash board is assigned to all rows of cells.

8 . The filling machine according to claim 7 ,
characterised in that the plurality of nozzles are connected to a preferably at least substantially horizontal nozzle pipe.

9 . A method for filling packages with fluid products with a filling machine, preferably according to claim 1 ,
in the case of which in a supply region packages to be filled are supplied in cells of a continuously circulating transport device, in the case of which the supplied packages are transported in the cells of the transport device from the supply region via a filling region to a discharge region and are filled at the same time, in the case of which the filled packages are discharged in the discharge region from the cells of the transport device, in the case of which the cells are returned from the discharge region to the supply region, in the case of which the cells are sprayed in the return region by at least one nozzle with a cleaning fluid and in the case of which the cleaning fluid sprayed by the at least one nozzle and passing the cells is collected and drained at least partially by a splash board provided on the side of the transport device facing away from the at least one nozzle and opposite the nozzle, and in the case of which the at least one nozzle sprays the cells in a deviation region of the transport device and the cleaning fluid sprayed by the nozzle and passing the cells is collected and drained in a deviation region of the transport device by the splash board.

10 . The method according to claim 9 ,
in the case of which the at least one nozzle sprays the cleaning fluid at least partially upwards, preferably largely horizontally, in particular at an angle of 5° to 20° to the horizontal against the cells and/or in the case of which the at least one nozzle sprays the cleaning fluid at an angle of between 5° and 35°, preferably of between 5° and 20° to the longitudinal extension of the cells against the cells,

11 . The method according to claim 9 ,
in the case of which the cleaning fluid is sprayed by the nozzle at least partially against a splash board formed at least in sections as a splash guard and/or in the case of which the cleaning fluid is sprayed by the nozzle at least partially against a side of the splash board at least partially, preferably largely pointing downwards and/or at least partially convexly curved and/or in the case of which the cleaning fluid collected by the splash board is drained to a tray provided in particular below the transport device.

12 . The method according to claim 9 ,
