Embodiments of the present invention will be described in detail with reference to the drawings.

In the drawing, reference numeral 1 denotes a filling cylinder, which is arranged downwardly in the opening 2A opened at predetermined intervals in the periphery of the bottom plate of the liquid storage tank 2 provided on the upper part of the rotation drive shaft (not shown). The liquid communication port 3 is opened near the center of the length of the peripheral wall. 4 is a receiving member provided on the upper end of the cylinder 1, the through hole 5 is opened in the center, and the liquid cylinder 6 is opened at predetermined intervals at the outer peripheral part. Reference numeral (7) is a fixed-quantity cylinder, which is attached to the rotating disc 8 attached to the drive shaft and integrally rotated through the attachment control 9 corresponding to each filling cylinder 1. (10) is a communication tube, one end is attached to the upper end of the metering cylinder (7), and the other end is inserted into the fitting portion (11) of the outer periphery of the filling cylinder (1) to be connected with the liquid communication port (3) The inside of the filling cylinder 1 and the metering cylinder 7 are connected to each other through this communicating tube 10 and the communicating port 3. (12) is a piston which slides freely into the fixed-quantity cylinder (7), the rod (13) slides freely into the attachment cylinder (9), and is always urged downward by the compression spring (14). The lower end of the rod 13 is provided with a roller 16 in contact with the cam 15 of the piston lifting and lowering action. The cam 15 is attached to the charger bed 39 via an attachment member 17 so as to be adjustable in position up and down. Reference numeral 18 denotes a lifting control, which is inserted into the filling cylinder 1 in a state in which the lower end thereof protrudes below the filling cylinder 1, and a partition wall having a through hole 20 opened in the center inside the upper portion thereof. 18A) is described. The partition wall 18A has an upper liquid introduction portion 21 and a lower liquid discharge portion 22 at an upper side thereof, and an upper liquid inlet 23 at a circumferential wall of the upper liquid introduction portion 21 at a lower liquid discharge portion 22. The lower liquid outlets 24 are respectively opened on the circumferential wall.

In addition, the lower end of the elevating control unit 18 is opened to form an injection port 19. Reference numeral 25 is a flange having a lateral air bleed hole 25A, which is attached to the lower end of the lift control 18, between the upper surface of the flange 25 and the end 1A of the filling cylinder 1. A coiled compression spring 26 is provided so that the lift control 18 is always pressed against the filling cylinder 1.

Reference numeral 27 denotes an edge bar, which slides through the through holes 5 and 20 freely, and an upper portion thereof has a lower stopper 28 having a step portion for defining a rising position of the edge bar 27. (29) is a deformed body, is attached to the lower end of the rim bar (27), and the leading edge thereof abuts against the periphery of the injection port (19), and receives the lifting control unit (18). 30 is an upper stopper made of a sleeve wound around the upper end of the fluctuation 27 and has an upper part 30A at its upper end, and a coiled compression spring between the upper part 30A and the receiving member 4. It is weaker than the compressive force of (26). Reference numeral 32 is a container table, and is fixed to an upper end of the lifting rod 34 which slides into the cylinder 38 provided at a position outside of the fixed-quantity cylinder 7 of the outer peripheral part of the rotating disc 8.

The lifting rod 34 is always pressed downward by the spring 35. Reference numeral 37 is a roller in contact with the cam 36 for container up and down operation, and is set at the lower end of the rod 34. 38 is fixed to the upper surface of the container stand 32 with the container receiving member.

In the above structure, in the container carrying-in part, the roller 37 is separated from the cam 36, and the maintenance stand 32 is lowered in the lower position by the compression force of the spring 35. As shown in FIG. In addition, since the lifting control 18 is pressurized by the compression spring 26, the lower end of the cylinder 18 contacts the deformable body 29, and the compression force of the compression spring 26 is stronger than the compression force of the compression spring 31. The rim 27 is also descending.

And since the sleeve 30 touches the receiving member 4, the lowering position of the elevating cylinder 18 is defined. In the lowered position of the elevating cylinder 18, the lower liquid outlet 24 is blocked by the inner circumferential surface of the filling cylinder 1, and the upper liquid inlet 28 coincides with the liquid communicating port 3. The injection port 19 is also blocked by the deformable body 29. In this state, the container A is moved on the holding base 32 and the position is determined by the receiving member 38. On the other hand, in the place where the upper surface of the cam 15 in front of or behind the container carrying part is descending, the roller 16 causes the compression force of the compression spring 14 along the upper surface of the cam 15 with the rotation of the rotary disk 8. The ascent is stopped. Since the container A is still rising, the lifting cylinder 18 also continues rising, and the injection port 19 opens. In the place where the lower liquid outlet 24 and the liquid communication port 3 coincide with each other, the lifting of the lifting cylinder 18, that is, the lifting of the container holding platform 32 is stopped. Since the piston 12 is raised to the predetermined position by the cam 15 via the rod 13, the liquid in the metering cylinder 7 is passed through the communication tube 10, the liquid communication port 3, the lower liquid outlet 24 and The container A is filled from the injection port 19 through the lifting cylinder 18.

When the filling of the liquid in the container A is completed by filling, the maintenance base 32 and the container A are filled in the container A. As shown in FIG. Out through the vent hole 25A of the flange 25. As the lowering and lowering of the container A together, the lifting cylinder 18 is also pressurized by the compression spring 26, so that the lower end of the cylinder 18 contacts the deformable body 27 and the injection port 19 is closed. Thereafter, the edge bar 27 is pressed against the compressive force of the compression spring 31. The lower liquid outlet 24 is blocked by the lowering of the elevating cylinder 18 by the inner circumferential surface of the filling cylinder 1, and the upper liquid inlet 23 and the liquid communicating port 3 coincide with each other so that the fixed quantity cylinder 7 is filled. In communication with the cylinder (1). Thus, the piston 12 is lowered to the predetermined position again, so that the liquid is introduced into the metering cylinder 7 from the liquid receiving tank 2. The container A, which is lowered to the lower limit position, is discharged to the outside from the maintenance stand 32 when it reaches the container discharge part. When the container A is not loaded on the maintenance stand 32, the elevating cylinder 18 is always pressurized by the compression spring 26, so that even if the piston 12 is raised, the fixed quantity cylinder 7 The liquid inside is only returned to the liquid storage tank 2 via the communication tube 10, the upper liquid inlet 23, and the filling cylinder 1. It is not discharged from the injection port 19 of the elevating cylinder 18.

The operation as described above is successively carried out with respect to the containers moved on each maintenance stand 32 in accordance with the rotation of the rotary disk 8, each container is automatically filled with a certain amount of liquid.

According to this invention, the filling amount of the liquid is determined in accordance with the up and down distance of the piston of the fixed-quantity cylinder, and it is possible to arbitrarily change the filling amount by always filling a certain amount and changing the up and down distance of the piston. Moreover, since the liquid flow path can be widened, even if mixed matter such as pulp is contained in the liquid, it can be filled smoothly and reliably without bursting. Further, after filling, the inlet is blocked by the deformed body, so that the balance does not drop.

Since the opening and closing of the communication cylinder of the filling cylinder and the fixed-quantity cylinder is opened and closed by the displacement of the lifting cylinder relative to the filling cylinder, it is an extremely simple structure without requiring a separate device, and is easy to manufacture, and there is little trouble. And since the liquid communication port is opened and closed by rolling up the lower end of the elevating cylinder to the circumferential part of the container, there is no need for any electric control or flow rate control means for detecting the container and operating the filling device with the detection signal. The configuration is further simplified.

In addition, since the air vent is drilled in the lower flange of the elevating cylinder, charging is performed smoothly. Also, the air vent is drilled in the transverse direction, so there is no risk of dust entering there.
