Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting a PET bottle as a beverage container.

[0002]

2. Description of the Related Art Disposal of a large amount of used PET bottles is performed by a compressor at a factory or a disposal site.
This was done by reducing the volume and providing it for recycling.

However, the used PET bottles to be transported to the disposal site are such as to carry air, which increases the transportation cost, and the disposal site requires equipment such as a compressor for mass processing. Have become larger and require dedicated workers, and because PET bottles are made to be extremely durable despite their light weight, they require a large amount of energy to compress, and have high energy costs and are inexpensive. Has been a major obstacle to recycling.

As a solution to such a problem (failure), there is a technique disclosed in Japanese Patent Application Laid-Open No. 8-197495. This disclosure technology, while the PET bottle is rotating on a disk, the mouth and bottom of this PET bottle is separated from the body by a mouth cutter and a bottom cutter, only the body is rotated by a rotating cylinder and conveyor. , And are compressed into a flat plate.

[0005]

However, in the above-described disclosed technology, the plastic bottle is cut off only at the mouth and the bottom and is separated from the body.
In order to compress the cylindrical body that occupies the largest volume into a flat plate, a rotating cylinder and a conveyor are required, and the cutting device for this PET bottle becomes larger and heavier. Need to be identified,
There were also problems in the transportation and production costs.

In the conventional PET bottle cutting apparatus, only the mouth and the bottom of the PET bottle are cut, and the cylindrical body occupying the largest volume remains as it is. When transporting used PET bottles to the disposal site, although the volume has decreased,
When a large number of used PET bottles are used, there is a problem that the volume becomes considerable and the transportation cost becomes high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to be small in size and light in weight, inexpensive in manufacturing cost, and in general household use.
It is an object of the present invention to provide a PET bottle cutting device which can be used with electric power of V and can be installed in a small space at a convenience store, a supermarket, a restaurant, an event venue, a meeting place of a neighborhood association, and the like.

[0008]

In order to achieve the above object, a PET bottle cutting apparatus according to the first aspect of the present invention comprises:
A bottle inlet at the upper end and a bottle outlet at the lower end, and a part of the PET bottle inserted from the bottle inlet is projected to the bottle outlet, and a bottle outlet of the inlet cylinder Cutting means for compressing a part of the protruding plastic bottle and cutting it in a circle.

With this configuration, a plastic bottle is inserted from the charging opening of the charging cylinder, a part of the plastic bottle is projected from the opening of the bottle, and a part of the plastic bottle is compressed by a cutting means and cut into a slice. can do.

[0010] As described above, the cutting means only needs to be configured so that the end of the PET bottle is compressed and cut into rings. As a PET bottle cutting device, it is possible to reduce the size and weight, and therefore, the production cost is also reduced. Inexpensive and for general household use 100
V power can be used, convenience stores, supermarkets,
It can be installed in small spaces at restaurants, event venues, neighborhood association gatherings, etc.

In addition, since the PET bottle is cut into a round slice, the volume can be reduced to about 1/8, and the transportation cost to the disposal site can be greatly reduced.

According to a second aspect of the present invention, there is provided a PET bottle cutting apparatus according to the first aspect, wherein the cutting means comprises a fixed blade body and a rotary blade body. With the rotation of the rotary blade, the rotary blade and the fixed blade sandwich a part of the plastic bottle projecting from the bottle outlet and compress and cut it.

[0013] With this configuration, a plastic bottle is thrown in from the throw-in port of the throw-in cylinder, a part of the PET bottle is projected from the bottle projecting port, and positioned between the rotary blade body and the fixed blade body. Due to the rotation of the body, the PET bottle is sandwiched between the rotating blade body and the fixed blade body and compressed in a state where the movement in the front-rear direction and the left-right direction is restricted by the charging cylinder body, and then the blade portion of the rotating blade body And the blade portion of the fixed blade body is cut into a round slice state.

As described above, the cutting means only needs to have the structure of the rotary blade body and the fixed blade body, so that the PET bottle cutting apparatus can be reduced in size and weight, so that the manufacturing cost is low and the manufacturing cost is low. It can be used with 100V power for general household use, and can be installed in a small space at convenience stores, supermarkets, restaurants, event venues, neighborhood association gatherings, and the like.

In addition, since the PET bottle is cut into slices, its volume can be reduced to about 1/8, and the transportation cost to the disposal site can be greatly reduced.

According to a third aspect of the present invention, there is provided a PET bottle cutting apparatus according to the third aspect, wherein the cutting means comprises a plurality of cutting means provided on a periphery of the rotating shaft. The rotating blades are fixed radially with the axis a of these rotating blades inclined at a predetermined angle α with respect to the axis b of the rotating shaft, and the rotating shaft is mounted on the apparatus main body, and the blade portion of the rotating blade is attached. At an angle α so as to approach the blade portion of the fixed blade body.

With this configuration, not only can the same operation and effect as those of the second aspect of the invention be achieved, but also because the axis a of the rotary blade is inclined at a predetermined angle α with respect to the axis b of the rotary shaft. The blade portion of the rotary blade body comes close to the blade portion of the fixed blade body at a predetermined angle α to cut the PET bottle in a compressed state, so that the PET bottle is cut smoothly.
For this reason, labor saving and rationalization of sharpness are achieved.
