Further, (3) is a thrust ring made of an oil-free bearing material such as MC nylon, and the thrust ring (3) is inserted and fixed to the substrate (2). In addition, (4) is a plurality of shafts (four in this example) implanted in concentric positions on the substrate (2), and (5) is a disk, each of the shafts (four in this example).
) is inserted into the hole of the disc (5), and the disc (
5) are fixed to each shaft (4) via screws (14). In addition, (6) is a plurality of levers (four in this example), (6") is a bush that is inserted into and fixed to the hole of each lever (6), and each lever (6) is a bush that is fixed to the hole of each lever (6). (6")
It is rotatably attached to each of the above shafts (4) via. Further, (7) is a plurality of (four in this embodiment) compression members, each of which is attached to the inner finger side of each of the levers (6). In addition, (8) is an annular rotating plate loosely fitted around the disk (5), and (8') is the tip of an arm provided on the rotating plate (8). is a drive device such as an air cylinder (not shown)
When the drive device is driven, the rotating plate (8) rotates about the central axis of the substrate (2).

Further, (9) is a plurality of (four in this embodiment) cam followers, each of which is attached to the lower surface of the rotary plate (8), and whose lower surface abuts the thrust ring (3). The cam follower (9) is rotatably supported on the thrust ring (3) together with the rotating plate (8). Further, (10) is a plurality of (four in this embodiment) cam followers, each of which is mounted on the upper surface of the rotary plate (8) and engaged with each of the levers (6).

Further, (11) is connected to a driving device (not shown) by a stoppering rod, and is moved up and down by driving the driving device. Further, (12) is a cork, and the cork (12) is fed from a supply device (not shown) to a disk (5).
through a central hole in the compressor to the compression position.

Moreover, (13) is a bottle, and the bottle holder (13) is supplied from a stand (not shown) to the position shown in FIG. 3, and after being capped, it is discharged from the same position.

(Function) Next, the function of the cork compression device will be explained. When the rotary table (1) is rotated by a drive device (not shown) and the nine cork compressors reach a predetermined position, the corks (12) and ]tK (13) are supplied to the position shown in FIG. At this time, the single cork compression device is in the state shown in FIG. Next, a drive device (not shown) such as an air cylinder connected to the tip of the arm provided on the rotating plate (8) drives the two rotating plates (8) around the central axis of the board (2). Arrow (a)
Rotate in the direction. At this time, each cam follower (9) moves on the thrust ring (3) while functioning as a bearing, assisting the rotation of the one-turn plate (8) and each cam follower (10) in the direction of arrow (a), and each lever (6) and each compression member (7) rotate in the direction of the arrow (b) about each axis (4), and the circular arc surface provided on the inner end side of each compression member (7)
) to compress the cork (12) as shown in FIG. Next, a drive device (such as an air cylinder) connected to the tip of the arm provided on the rotary plate (8)
(not shown) is driven in the opposite direction to the above to rotate the plate (8) twice.
rapidly rotates in the direction of arrow (b) around the central axis of the substrate (2). At this time.

A driving device (not shown) for the capping rod (11) is driven, the capping rod (11) is lowered, and the cork (12) is placed in the bottle (13).
The mouth of the bottle is corked. The rotating plate (8) and the arm (8), which have rapidly rotated in the direction of the arrow (B) as described above, gradually decelerate, and each cam follower (10) rotates as shown in FIG.
comes into contact with the deep part of the U-shaped notch of each lever (6),
Stop. Moreover, after the above-mentioned capping, the capping rod (11) rises,
The bottle (13) is also ejected by an ejector (not shown), completing one cycle of capping. At this time, the rotary table (1) rotates once and each part of the cork compression device returns to its original position. Thereafter, the above-mentioned action is repeated, and the capping is performed one after another. The above is the effect when the present cork compression device is applied to a corking machine with a turret and multiple heads, but the same effect is performed in a corking machine with a fixed one-rotation table.

(Effects of the Invention) As described above, the cork compression device of the present invention is rotatably attached to a donut disk-shaped substrate, a plurality of shafts installed at concentric positions on the substrate, and each of the shafts. a plurality of levers, each having an arcuate surface for compressing cork, each of which is attached to an inner end of each lever; and a plurality of compression members each having an arcuate surface for compressing cork, and rotating each of the levers by rotating around the central axis of the board. It is equipped with a rotating plate and a rotation drive mechanism that rotates the rotating plate, and each compression member rotates without sliding friction and compresses the cork in the direction of diameter reduction, so lubricating oil is applied to the lubricated part. There is no need for this, and there is no risk of metal wear particles adhering to the cork, and it is possible to prevent lubricating oil and metal wear particles from adhering to the cork. In addition, since the cork compressed in the diametrical direction is released and the cork is plugged at the same time, a small driving force is required, and damage to the cork can be prevented. In addition, there is less wear on parts and the center of the cork does not change after compression.
It has the effect of stably sealing the cork.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to these embodiments, and can be modified in various ways without departing from the spirit of the present invention.
