Rotation of barrel 3 by 0d and label 5 by collection means 33
There is no hindrance during the suction of the label, and the pressure rollers 10a, 10b, 10c, and 10d roll on the label 5, so that the label 5 attached to the barrel 3 can be effectively peeled off. It will be possible.

Further, as a cutting means, a hot air jet nozzle 30
Although the cutting means is not limited to this, for example, it is composed of a heater having a heating wire and the heater is brought into contact with the label 5, or it is composed of a cutter to cut the label 5. It may be one.

Moreover, the label 5 may be made of a heat-shrinkable film or a paper sheet in addition to the stretch film, and the upper portion of the barrel 3 can be freely attached and detached as shown by a phantom line in FIG. Pressing rollers 10e and 10f for pressing may be provided. In addition, the container is not limited to the barrel 3, and may be a bottle filled with drinking water or the like, and the design of other constituent members can be arbitrarily changed.

[0034]

As described above, according to the present invention, when the tubular label fitted in the container is cut by the cutting means and the cut label is sucked and collected by the collecting means, the label is pulled by hand. Since the label that has been cut while being sandwiched by the means and rotating the container is drawn by hand and the label is sucked and collected by the collecting means, even when the label and the container are blocked, As described above, the suction error does not occur, and the label can be surely sucked and collected.

Further, when a rotary roller capable of pulling the cut label by hand is provided at the tip of the pulling means so as to be rotatable, the rotation of the rotary roller ensures that the label is removed from the container. It can be peeled off and pulled by hand.

Further, when a rotating means for rotating the container so that the label is sucked by the collecting means is provided at the time when the pulling means is separated from the container, it is particularly difficult in the conventional case such as a beer barrel. Even when a large-sized container or a water drop is attached between the label and the container, the label can be effectively peeled from the container.

When the label is made of a stretch film and the cutting means is a hot air jet nozzle for jetting hot air, the label can be reliably held by the pulling means by utilizing the stretching force of the label and the hot air can be surely held. The label can be easily fused and the label can be collected easily and quickly, which is very practical.
