Therefore, as shown in FIG.
49 is the capping position 4 of the star wheel 1 for capping
The position of the chuck 49 between the capping position 4 and the cap receiving position 85 does not change while moving to the cap receiving position 85.
The rotation is performed by the motor 45 in synchronization with the rotation of the motor 19.

Next, the operation of the above embodiment of the present invention will be described. First, the container 13 is guided by guides on the upper side of the container 13 by a container transport conveyor (not shown), is taken in on the rotary table 5, is guided by the star wheel 1, and is marked by the mark positioning means 8 to mark (print) the container 13. ) Is directed in a certain direction and moves to the capping position 4.

On the other hand, the cap 15 is transferred from the turntable 14 to the conveyor 16, and the wings 15 B are sent forward or backward by the cap conveyance guide 17 to the cap 38. Contact, the cap 15 with the wing 15B facing backward rotates the cap 15 by 180 degrees, the wing 15B becomes forward, and the wing 15B
15 is constrained by the wing guide bar 17B and does not rotate. The wings 15B are intermittently fed to the chucking position without changing the direction of the wings 15B.

The chucking position, that is, the cap receiving position 85
First, since all the grips 55 and 56 of the chuck main body 57 are opened and rotated by the arm 44 in a state where the grips 55 and 56 are open (see FIG. 13), the cap 15 and the chuck 49 are simultaneously rotated at the position 85 with good timing. When stopped, the chuck 49 is lowered by the vertical movement means, near the end of lowering, the grip closing cylinder 60 is operated, the grip opening / closing cam 59 is advanced, and the upper and lower grips 55 and 56 are simultaneously closed. As shown in (5), the cap portion 15A and the wing portion 15B of the cap 15 are simultaneously grasped respectively.

When the cap 15 is gripped by the chuck body 57, the chuck 49 rotates while being turned upside down by the arm 44, and the cap 15 reaches the capping position 4 and is positioned immediately above the mouth of the container 13 to stop the operation. Once in,
Subsequently, the chuck main body 57 is lowered by the chuck up / down moving means, and the cap 15 is mounted on the mouth of the container 13. At this time, the cap 15 is pressed against the mouth of the container 13 by the lower cap portion grip 56, and the cap mounting coil spring
It is safely and securely crowned by the cushioning action of 62.

When the cap 15 is completely attached to the opening of the container 13, the air for operating the cylinder 60 of the chuck 49 is released, and the chuck body 57 is moved by the grip opening spring 61 in FIG.
Open as shown in
As 49 rises, the capping star wheel 1 and the chuck 49 move intermittently at the respective timings.

Thus, the chuck 49 of the cap 15
Chucking operation and capping operation are smoothly performed, and the wing portion 15B of the cap 15 is positioned at the mark position of the container 13.
Can be capped together. The present invention
The present invention is not limited to the above embodiment, and the design can be changed as appropriate.

[0033]

According to the present invention, the wings of the cap are fixed.
Into the chuck means aligned in the direction of
