(6) Operation Next, the operation of the umbrella label mounting device will be described.

[Supply of umbrella labels]
The umbrella label B manufactured in the shape of a truncated cone by the supply means 20 of the umbrella label B shown in FIG. 1 is sequentially supplied to the belt conveyor 25 at a predetermined interval.
The umbrella label B mounted on the belt conveyor 25 with the small-diameter side facing up and the large-diameter side facing down moves toward the starting end of the stepped sliding floor 30.
The umbrella label B transported while maintaining the horizontality is guided and allowed to stand on the upper surfaces of the start ends of the pair of step plates 31 and 32 constituting the step sliding floor 30.

[Container supply]
On the other hand, the container A is transferred from the right side to the left side of the drawing through the container conveying means 10.

[Swivel of feed tube]
As the chain 53 positioned above the belt type conveyor 12 rotates in the clockwise direction in FIG. 1, the plurality of support shafts 54 provided on the chain 53 start turning all at once.
Along with the turning movement of the support shaft body 54, the elevating shaft 55 penetrating the support shaft body 54 rotates together with the feed tube 56.

  The timing of the umbrella label B and the container A and the timing of the feed tube 56 are synchronized with each other, and the transport speed of the container A and the turning speed of the feed tube 56 are the same. Under this premise, the umbrella label B is attached to the neck of the container A by the raising and lowering operation of the feed tube 56 described in detail below.

[Drop of umbrella label]
The operation of attaching the umbrella label B will be described with reference to FIG.
As shown at the right end of the figure, immediately after the start of the mounting section, the feed tube 56 is located immediately above the umbrella label B.
The umbrella label B placed across the upper surfaces of the start ends of the pair of step plates 31 and 32 constituting the step sliding floor 30 is pushed at the rear part thereof by the pusher 54b, and the upper surfaces of the pair of step plates 31 and 32. Glide.
As the roller 57 moves down along the guide surface of the lifting guide rail 42 in parallel with the moving process in which the umbrella label B is moved toward the left in FIG. The feed tube 56 at the lower end of 55 is lowered.
As a result, the lower open end of the feeding cylinder 56 is placed on the upper part of the umbrella label B so that the umbrella label B can be conveyed by the feeding cylinder 56, and the lowering of the feeding cylinder 56 is stopped.
Thereafter, the umbrella label B slides on the upper surfaces of the pair of step plates 31 and 32 following the movement of the feed tube 56, but every time it passes through the step portions of the pair of step plates 31 and 32, the lifting guide rail 42. The feed tube 56 descends following the lowering of the roller 57 along the guide surface.
As a result, the umbrella label B continues to slide smoothly on the upper surfaces of the pair of stepped plates 31 and 32 with steps while maintaining the horizontality.

[Attachment of umbrella label]
The conveyance speed of the umbrella label B by the feed tube 56 and the conveyance speed of the container A that continues to move under the umbrella label B are constant.
Therefore, as the feed tube 56 moves, the umbrella label B is gradually guided downward, and the opening of the umbrella label B is gradually inserted into the neck of the container A.

Immediately after the umbrella label B passes the end of the pair of step plates 31 and 32, the feed tube 56 forcibly descends the umbrella label B, and the attachment of the umbrella label B to the neck of the container A is completed.
[Rise of feed tube]

When the attachment of the umbrella label B is completed, as shown in the left end of FIG. 4, as the roller 57 rises along the guide surface of the lifting guide rail 42, the feed tube 56 at the lower end of the lifting shaft 55 rises and the container Leave A.
By repeating the above steps, the umbrella label B is sequentially attached to the neck of each container A that is continuously supplied.

As described above, a simple mechanism that combines the feed tube 56 locked to the umbrella label B and the stepped sliding floor 30 that supports the umbrella label B forcibly moves downward while conveying the umbrella label B. Can be pushed down.
Therefore, the umbrella label B can be forcibly fitted into the neck portion of the container A while maintaining the level of the umbrella label B without being affected by air resistance.
In other words, there is no fear that the umbrella label B being mounted is tilted or the mounting timing is shifted. Therefore, it is possible to completely eliminate the installation mistake of the umbrella label B.

In particular, even if the mounting speed of the umbrella label B is increased, the accuracy of the lowering operation of the umbrella label B is not affected, so that the apparatus can be operated at high speed.
