[0019]

Next, the operation of the labeling machine will be described.

<B> Label supply (Fig. 2)

The tape pulled out from the roll 2 is cut into a label having a predetermined size by the rotary cutter 3, and the label transferred to the peripheral surface of the sticking drum 5 via the relay drum 4 is cut by the gluing device 7. The glue is applied to the transport device 8.

<B> Supply of container (FIGS. 2 and 3)

On the other hand, the container 12 is sequentially supplied to the conveying device 8 through the screw conveyor 10 and the inlet star 11 with the handle 12a having an irregular orientation. Over the interval L ₂ in FIG. 2, the sheath 36 is lowered of the mounting table 23 shown in FIG. 3, also 12 accept preparation of containers have to rise retainer 30 and the regulating plate 54 is made. When the container 12 transferred to the mounting table 23 in this state plunges into the section L ₁ of FIG. 2, the outer cylinder 36 of the mounting table 23 of FIG.
0 descends and holds the top and bottom of the container 12. The held container 12 receives the rotation of the mounting table 23 and starts rotating (spinning). Further, when the container 12 passes through the section L ₁ in FIG. 2, the roller 56 is disengaged from the swing guide plate 27 as shown in FIG. 7, and the connecting arm 55 is moved by the spring force of the return spring 59.
It swings in the counterclockwise direction about 2, and the regulation plate 54 at the tip of the swing arm 53 descends toward the peripheral surface of the container 12. The regulating plate 54 elastically contacts the peripheral surface of the container 12 by the spring force of the return spring 59, but the upper and lower sides of the container 12 are restrained, so that the elastic contact of the regulating plate 54 does not cause the container 12 to fall. A handle 12a that continues to rotate with the container 12 as shown in FIG.
When approaching the restriction plate 54 and reaching the position of the cutout 54d of the restriction plate 54, the restriction plate 54 loses the supporting member and slightly advances to insert the handle 12a of the container 12 into the cutout 54d. When the container 12 tries to continue to rotate further, the handle 12a comes into contact with the latch arm 54b of the regulation plate 54 to prevent the rotation.
If the container 12 is forcibly continued to rotate, the handle 12a gets over the locking arm 54b of the regulation plate 54 and the direction cannot be corrected. However, as shown in FIG. Since the friction clutch 35 interposed between the support shafts 31 slips and only the pulley 32 idles, the rotation of the container 12 remains blocked. In this way, since the containers 12 can be rotated and the rotation of the containers 12 can be stopped via the handle 12, all the containers 12 can be corrected in a predetermined direction during transfer.

<C> Labeling

In FIG. 2, the container 1 whose direction has been corrected
2 approaches the sticking drum 5, meets the label adsorbed on the peripheral surface of the sticking drum 5, and the label is stuck at a predetermined position of the container 12. Immediately before the start of attaching the label, the regulation plate 54 shown in FIG. 1 rises, the pressing tool 30 that holds the top of the container 12 rises, and the outer cylinder of the mounting table 23 that holds the bottom of the container 12 descends. Then, preparation for taking in the next container 12 is prepared. The container 12 discharged from the conveying device 8 between the sticking drum 5 and the curved finishing guide 15 receives the rotational force from the sticking drum 5 to rotate, and further receives the rotational force of the finishing belt 16 to continue the rotation and carry out. Move 13. When the carry-out path 13 is moved, the peripheral surface of the container 12 is stroked by the finishing belt 16 and the finishing plate 17 to finish the attached label.

[0026]

Since the present invention is as described above,
It has the following effects.

<B> Since the regulation plate for locking the handle of the container is swingably supported, the direction of the container can be corrected easily and accurately.

<B> The mounting table can be rotated by a simple belt drive system, and the mechanism for forcibly rotating the container can be greatly simplified.

<C> Since the mounting table that supports the bottom of the container can be driven to impart the rotational force to the container, the rotational force can be reliably imparted even if the container is a soft material.

<D> The intermittent rotation of the mounting table can be easily controlled by the friction clutch. Therefore, it is possible to prevent the container from rotating carelessly after the direction of the container is regulated.

<E> The original performance of the rotary type transporting device can be fully exerted, and high-speed labeling of containers with handles becomes possible.
