Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a belt cutting / removing device for automatically cutting and removing a belt wound around the outer circumference of a carrying container, for example.

(Prior Art) Drinking water such as beer or juice is supplied to the market after being filled in bottles, etc., then placed in a box-shaped transport container in which a predetermined number of bottles are stored in an aligned state, and collected after sale. The bottles are stored again in the transport container and collected, and after being washed, they are filled with drinking water again and put on the market.

In recent years, in the beer industry, varieties of beer have been diversified, and different types of beer bottles are stored in the same-shaped carrier container and distributed in the market.

When bottles containing different types of drinking water are stored in the same-shaped transport container and distributed in the market as described above, the label attached to the bottle in the transport container cannot be seen at the distribution stage or the storage stage. Not only does it take time to confirm the types when sorting and handling, but it also causes erroneous delivery.

In order to eliminate such an inconvenience, conventionally, a sheet indicating a product type has been put in a position visible from the outside in a transport container.

(Problems to be Solved by the Invention) However, the above-described conventional method of putting a sheet in a transport container leads to an increase in cost and is inefficient because the work is manually performed, and improvement has been desired. Therefore, it is proposed to wrap a belt-shaped label indicating the type on the side surface of the transport container.

The present invention is intended to be used for other products when the transport container returned from the market after being wrapped with the strip label is to be removed from the transport container. The object of the present invention is to provide a band-shaped material cutting / removing device capable of automatically cutting and removing the band-shaped material wound around a carrier container such as a band-shaped label without damaging it.

(Means for Solving the Problem) As a means for solving the problems of the above-described conventional technology, the present invention is a conveyor for conveying a container around which a strip is wound, and a vertical position adjustment on one side of this conveyor. A lift table that can be installed, a belt-shaped object suction nozzle that sucks the band-shaped object that is arranged on the lift table to separate from the container, and a suction nozzle that is arranged on the lift table near the suction nozzle. A cutter that presses and cuts a site separated from the container of the sucked band-shaped object, and a band-shaped cut piece supported by a support arm that is installed across the conveyor on the elevating table and extends to the opposite side of the conveyor. A belt-shaped material recovery nozzle for sucking and removing the material from the container and a suction source connected to each of the nozzles are provided, and the belt-shaped material suction nozzle sucks the belt-shaped material wound around the container to be conveyed. thing It is characterized in that the slack portion caused by the above is pressed against the cutter to cut it, and then the collection nozzle sucks and removes.

(Operation) On the conveyor, when the transport container around which the strip is wound is transported, when approaching the position of the strip suction nozzle, a part of the strip is sucked by this nozzle and separated from the transport container, The slack portion formed by this separation contacts the cutter and is cut. The cut strip is sucked by the strip collecting nozzle on the opposite side, and is sucked and removed by peeling it from the periphery of the transport container.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.
