DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a stopper supply device for supplying stoppers one by one in order to attach stoppers to a liquid container made of paper.

[Prior Art] Recently, a paper box container 10 as shown in FIG. 3 is filled and preserved with a beverage such as fruit juice or sake, and a mouth plug 12 is attached to this and the beverage is taken out by breaking the mouth plug 12. Things are on the market. The box container 10 is made by bending a paper whose inner surface is coated with a synthetic resin into a box shape, and sealing the sides, the bottom and the top by heat welding. The upper part of the container is closed in the shape of a gable roof, and the spout 12 is attached to one of the inclined surfaces by heat welding.

When attaching the stopper 12 to the container 10, a stopper attaching device is used. In the spout installation device, a container already filled with a beverage is intermittently conveyed by a conveyor, and when the container is temporarily stopped, only one spout is transferred from the spout supply device to the spout installation device. Mount on top of container.
The spout supply device is provided above the transfer conveyor so as to intersect the conveyor.

As shown in FIG. 4, the mouth plug supply device includes a vertical chute 2
And a drop-out prevention guide 3 provided along the vertical chute 2.
And a pair of cylinders 4 provided on the sides of the vertical chute 2
And a spout pushing means (not shown) horizontally provided so as to intersect the vertical chute 2 at the pushing position 6 at the lower end of the chute. When supplying the stoppers 12, the pair of cylinder rods 5 are alternately projected into the passage of the vertical chute 2 and the stoppers 12 in the vertical chute 2 are dropped one by one to the lower end of the chute to push out the stoppers 12. Push out at position 6 towards the spigot attachment device (not shown).

However, in this type of plug supply device, since the plug 12 is pushed out in the crossing direction of the vertical chute 2 at the pushing position 6, it is not possible to provide the drop-out prevention guide 3 up to the lower end of the vertical chute 2 and the Stopper plug 12 if dropped
