The supply, stoppage, and exhaust of the pressurized fluid to the cylinder 43 are arbitrarily controlled by remote control by a control means (not shown).

Therefore, in the lid application processing according to the embodiment of the present invention, first, the cap support 4 is rotated by the pivoting means 19 so as to correspond to the lower side of the lid application member 3, and then the lid supply means (not shown). The cap c which is not aligned in the direction sent from
Are supplied to the cap support 4. A plug-type cap was used as the cap c.

The rotating shaft 2 hung from the machine body 1 in the capper A is not rotated by the release of the clutch 40, and the cover member 3 is lowered by the elevating means 12 so that the cap support body 4 is placed on the cap support body 4. The outer periphery of the cap c is grasped, and the table 10 is provided below the cover member 3.
A filled container b is supplied on top.

In this state, the stopper 5 is rotated by the rotating means 32 so that the engagement edge 28 of the engagement body 29 is brought into contact with the outer periphery of the cap c. Is set to an appropriate position for applying the projection c2 of the cap c to the container b.

Next, when the clutch 40 of the rotary shaft 2 is put in,
The rotating force of the rotating means 11 is transmitted to the cover member 3 and the cap c grasped starts rotating on the cap support 4.

While the cap c makes one revolution, the cap c
Since the stopper 5 which is in contact with the outer circumference of the cover 5 abuts on the projection c2, the rotation of the cover member 3, that is, the rotary shaft 2 is restricted, so that the rotation of the rotary shaft 2 is prevented by the pressure relief means 6.
The cap c is stopped on the cap support 4 and a predetermined positioning is performed.

By releasing the clutch 40, the rotary shaft 2
Is stopped, the stopper 5 is returned to the original position by the rotating means 32, and the cap support 4 is retracted by the rotating means 19 as the rotating shaft 2 is raised by the elevating means 12.
Again, the rotating shaft 2 descends, and the cap c held by the covering member 3 is pushed into the mouth of the container b to complete the covering.

If these operations are continuously performed, the cap c having the orientation thereof aligned in one direction is applied to the supplied filled container b.

[0047]

The present invention configured as described above has a slight projection like a hinge cap, so that even if the cap is difficult to align in a direction with a direction aligning machine, the cap can be securely attached at the time of applying the lid. The cap is placed in a state where the caps are aligned in a uniform direction with respect to each cap so that the liquid filled in the container does not stain the container, the label, or the printing surface. Since the cap is placed in the most suitable direction according to, the liquid can be poured easily, and the product itself can be easily displayed in the store.

Further, since the caps are aligned in the final direction when the lids are applied to the container, misalignment or error is reduced, and stable lids can be accurately aligned in the correct orientation.

In the case of a normal cap, the stopper can be removed and the cap can be used as a normal cap for tightening or pushing, and one cap can be used for a wide variety of caps. It has special effects such as.
