Abstract

PURPOSE:To simplify the structure of a charging machine provided with a washing circuit in addition to a charging circuit and a gas circuit and change over between the gas circuit and the washing circuit by a simple operation. CONSTITUTION:Charging nozzles 22 are fixed every interval in a casing 20. A charging machine is provided with a liquid valve 18 opening or closing the pass to feed liquid into the charging nozzles and a gas valve 26 opening or closing the gas line between the casing and the charging nozzles. A washing liquidrecovery pipe 30 is fitted to the upper part of casing so as to be relatively movable up-and downward. The washing valve 36 is constituted of this pipe and the upper part of charging nozzle. The pipe and the charging nozzle are raised and lowered by a cam 12. The above pipe is forced to stop by a stopper 40 when the casing raises or lowers more than specified positions. On washing, the cam is positioned lower than that in charging and the pipe is relatively raised against the casing and the washing valve is opened.

The operation of the filling machine having the above structure will be described. During normal operation, the cam 12 arranged at a predetermined height moves the valve lifter 6 up and down while the rotary table 2 makes one rotation, and the filling mechanism 6 fills the container B. First, in the container supply unit, the cam follower 10 is pushed up by the cam 12 to raise the valve lifter 6 to the highest position so that the nozzle portion 22a at the lower end of the filling nozzle member 22 does not interfere with the container B, and the container base 9 Supply container B on top. At this time, the stopper 40
Is raised to a high position where it does not come into contact with the rotary table 2, the cleaning liquid recovery pipe 30 is urged downward by the compression spring 39, and the inner peripheral surface (valve seat) 30 of the lower end portion thereof is

Then, as the rotary table 2 rotates,
When the locus of the cam 12 is lowered, the valve lifter 6 is lowered and the nozzle portion 22a is inserted into the container B (state in FIG. 1). Even at this position, since the stopper 40 floats on the rotary table 2 as shown in the figure, the cleaning valve 36 is closed by the compression spring 39, and the rotation of the rotary table 2 causes the filling mechanism 6 and the container B to be integrated. While rotating, the liquid valve 18 is opened for filling. During this filling, the gas valve 26 is also opened to inject air, nitrogen gas, or the like into the container B from the gas supply passage 28 between the casing 20 and the filling valve member 22. In this way, during normal operation, even if the valve lifter 6 moves up and down, the stopper 40 does not contact the upper surface 2a of the rotary table 2, so that it does not act as a stopper and the cleaning liquid recovery pipe 30 is always urged downward by the compression spring 39. The cleaning valve 36 is closed.

Next, the case of cleaning the filling machine will be described. At the time of cleaning, the cleaning cup C is arranged immediately below each filling mechanism 6. Then, the gas valve 26 is closed, and the cam 12 is further lowered below the filling position shown in FIG. 1 (see FIG. 3). Then, the cam follower 10 attached to the lower end of the valve lifter 6 is lowered by the cam 12, and the valve lifter 6 and the liquid supply pipes 14 and 16, the cylindrical casing 20, the filling nozzle member 22 and the like fixed to the valve lifter 6 are integrated by their own weight.

In the container supply part to which the container B is supplied at the time of filling, the locus of the cam 12 is at the highest position, and the lowering of the cleaning liquid recovery pipe 30 is stopped as described above, and the cleaning liquid recovery pipe 30 is fixed to the valve lifter 6. Since the filling nozzle member 22 is also stopped from descending by this cam 12, the cleaning valve 36 including the inner peripheral surface (valve seat) 30a of the lower end portion of the cleaning liquid recovery pipe 30 and the upper end portion (valve body) 22d of the filling nozzle member 22 is closed. ing. When the rotary table 2 rotates from the above state, the locus of the cam 12 gradually descends.
Valve lifter 6 and casing 20 fixed to this
And the filling nozzle member 22 further descends. While the cleaning liquid recovery pipe 30 is stopped, the casing 20
Since the filling nozzle member 22 descends against the compression spring 39, the cleaning liquid recovery pipe 30 relatively rises, so that the rubber packing 34 fitted to the upper end portion of the filling nozzle member 22 is replaced with the cleaning liquid recovery pipe. The cleaning valve 36 is opened away from the inner peripheral surface 30a of the lower end portion of 30 to form a cleaning circuit. The lower limit of the valve lifter 6, the casing 20 fixed to the valve lifter 6, and the filling nozzle member 22 is regulated by the cleaning cup C, and the cam follower 10 of the valve lifter 6 is separated from the cam 12.
