The elevating shaft 31 includes a head portion 31 a formed larger than the shaft portion of the shaft 31 and an elevating mechanism. When the elevating mechanism is operated and the shaft 31 is lowered, the head portion 31a comes into contact with the head portions of the fan-shaped rotating plate 30 and the connecting member 33, and as shown in FIG. Pushing down, the fan-shaped rotating plate comes into close proximity to the flange 32a of the hollow shaft. Thereby, the elastic member 34 will be in the compressed state. Further, in this state, the tip 51 of the nozzle 5 of the liquid discharge unit 4 to be described later approaches the opening of the container 10 or enters the opening so that liquid can be injected from the opening. In particular, it is preferable that the elevating mechanism raises the intermittent rotary table 3 immediately before the end of the rotation of the rotary table 2 in the forward rotation direction and lowers it after the end of the reverse rotation.

  A plurality of liquid ejection units 4 are mounted on the intermittent rotation table 3.

Further, the arrangement angle is the same as the arrangement angle of the plurality of container holding portions 21 of the turntable 2. For this reason, the arrangement pitch (fixed pitch) of the plurality of container holding units 21 arranged on the same circumference of the rotary table 2 and the arrangement pitch of the liquid ejection units 4 arranged on the intermittent rotary table 3 are the same. It has become.

A lower flange 44 is provided at the lower end of the lower tubular portion 41, and a side flange 43 is provided at the end of the side tubular portion 42. A liquid supply pipe 62 of the liquid supply unit 6 is connected to the side flange 43.

The liquid discharge unit 4 includes a filter 45 arranged so as to cross the inside. As the filter 45, a layered portion of mesh filters having different eye roughness can be preferably used. The mesh filter is preferably laminated so that the mesh becomes finer from the upstream side toward the downstream side.
In this embodiment, the filter 45 is provided at a position near the opening of the nozzle 5 and slightly upstream. Specifically, the filter 45 is accommodated in the upper flange 53 of the nozzle 5. Further, an inner cylinder portion 48 is accommodated in the lower portion of the main body portion 40 of the liquid discharge portion 4 and the lower tubular portion 41. The lower end portion of the cylindrical portion of the inner cylindrical portion 48 prevents the filter 45 from moving upward.

The liquid can be discharged from the nozzle 5. In the state shown in FIG. 9, the valve 47 is positioned below, and its side surface is in liquid-tight contact with the valve seat 49 to block communication between the side tubular portion 42 and the lower tubular portion 41. In this embodiment, the valve 47 descends toward the opening of the nozzle 5. For this reason, the final liquid discharged from the liquid discharge unit is strongly discharged, and the liquid breakage is good.

In this embodiment, the nozzle 5 is provided with a filter housing recess. The cylindrical part 50 has a completely short cylindrical part. Further, the inner diameter of the cylindrical portion 50 is substantially equal to the inner diameter of the inner cylindrical portion 48. For this reason, it is substantially impossible to hold the liquid to be filled.

The nozzle 5 extends downward from the cylindrical portion 50 and a portion that is on the outer side in the normal direction of the rotary table 2 of the cylindrical portion 50 (in other words, a side to which centrifugal force is applied when the intermittent rotary table rotates in the traveling direction). And a nozzle tip 52 provided so as to narrow toward the tip 51. Further, the nozzle tip 52 extends downward from the cylindrical portion 50, faces the rotation axis direction of the intermittent turntable 3 (and the turntable 2), and further decreases in width toward the tip.
A centrifugal force is applied to the nozzle tip 52 in such a form when the intermittent rotary table rotates in the traveling direction, and the liquid adhering to the nozzle tip 52 rises up the intermittent rotary table 3 after filling the fixed amount chemical solution. The applied centrifugal force is expressed in the swinging section (before entering the minute speed reduction section when ascending) and reliably drops in the container opening located below. In the apparatus of the present invention, the rotary plate 30 is swung for a certain interval under the condition that the valve is sealed and the liquid is not supplied, and the remaining adhering to the inner wall of the nozzle 5 is caused by the centrifugal force generated at that time. All the liquid is discharged into the bag. As a result, when the fan-shaped rotating plate 30 is raised and returned, there is no residual liquid on the inner wall surface of the nozzle, so that no liquid dripping occurs.

In this embodiment, the nozzle tip 52 is formed such that the widths of both side portions 54a and 54b abruptly narrow toward the tip 51 having a slight roundness. As shown in FIG. 11, the start ends of both side portions are located in the vicinity of the center of the cylindrical portion 50, and as shown in FIG. 10, the side portions 54a and 54b of the nozzle tip portion 52 are curves that curve inwardly. And ends at the tip 51. The nozzle tip 52 has a cutting edge shape having inner and outer surfaces (both sides 54a and 54b) curved inward .

And the protrusion length B from the cylindrical part of the nozzle front-end | tip part 52 is preferably 8-15 mm, and it is especially preferable that it is 10-12 mm. Moreover, it is preferable that the internal diameter L of the cylindrical part 50 is 8-12 mm. The length of the tubular portion 50 of the nozzle tip 52 (the length C from the lower end of the filter 45 to the lower end of the tubular portion 50 is preferably 0.5 to 1.0 mm. Further, both side portions of the nozzle The curvature of 54a and 54b is preferably R8 to 15 mm.

1 and 2 illustrate the positions of the start point and the end point in a state where the intermittent rotary table 3 (fan-shaped rotary plate 30) is lowered. In the raised position, the intermittent rotating table 3 (fan-shaped rotating plate 30) in FIG. 1 is positioned slightly on the reverse rotation side from the illustrated position, and the intermittent rotating table 3 (fan-shaped rotating plate 30) in FIG. Therefore, it is located slightly on the rotation side in the traveling direction. Further, the intermittent rotary table 3 (fan-shaped rotary plate 30) rotates in the traveling direction at the same speed as the rotary table 2 (disk-shaped rotary table 20) in the lowered state shown in FIGS.
In the liquid filling apparatus 1 of this embodiment, the intermittent rotary table 3 (fan-shaped rotary plate 30) is lowered while rotating in the traveling direction.

It becomes a state. Then, the valve 47 is opened, and liquid filling is started. In addition, in the state shown in FIG. 4, in other words, the elevating shaft 31 is lowered, and the fan-like rotating plate 30 is pushed down by the head portion 31 a of the shaft 31 to rotate in the traveling direction. When the fan-shaped disk portion 30 rotates in the direction of travel (descent), the valve 47 of the liquid discharge unit 4 is located above, the valve opens, and the liquid is discharged downward from the nozzle 5. It is injected into the container 10 located at.

  Then, immediately before the intermittent rotary table 3 (fan-shaped rotary plate 30) reaches the state shown in FIG. 2, the valve 47 is closed and the liquid injection is completed. The residual liquid of the nozzle 5 is dropped into the container 10 by the centrifugal force applied to the nozzle 5 after the valve 47 is closed. Further, the intermittent rotation table 3 rises while continuing the rotation in the traveling direction without stopping suddenly. Specifically, the fan-shaped rotating plate 30 continues from the state shown in FIG. 4 until it reaches the state shown in FIG. At the same time, the direction of rotation changes, and the process proceeds to reverse rotation. Then, the reverse rotation is performed until it is slightly on the reverse rotation side from the position of the intermittent rotation table 3 (fan-shaped rotating plate 30) shown in FIG. Then, the intermittent rotation table 3 does not stop abruptly and continues to rotate in the reverse direction until it slightly exceeds the position shown in FIG. Specifically, the fan-shaped rotating plate 30 continues from the state shown in FIG. 3 until it reaches the state shown in FIG. The direction of rotation changes and shifts to the direction of rotation. Then, a series of operations of rotation in the advancing direction, ascent, reverse rotation, and descent are repeated.
