DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PET bottle processing apparatus for heating and compressing a polyethylene terephthalate container (hereinafter referred to as a PET bottle) for holding drinks and the like to promote the reuse of resources.

[0002]

2. Description of the Related Art Conventionally, as apparatuses for heating and compressing plastic waste, there are a processing apparatus described in JP-A-2-6105 and a processing apparatus described in Japanese Utility Model Laid-Open No. 4-114485. The former treatment device is a device for removing plastic waste containing vinyl chloride having a large composition fluctuation due to foreign matter at a low cost, and the latter device bends and stretches while heating a plastic packaging container with a heater. A device that compresses with an arm.

[0003]

However, all of the conventional processing apparatuses are processing apparatuses for discarding plastic waste, and are not used to promote the reuse of resources. Moreover, the conventional processing apparatus is a final processing apparatus used by a so-called industrial waste disposal company, and an apparatus used to promote the reuse of resources in each household has not yet been proposed.

[0004] On the other hand, PET materials, which are made of carbon, hydrogen and oxygen and have excellent properties in strength and hygiene safety by being stretched, are increasingly demanded as PET bottles every year. However, in order to grind this PET bottle and reprocess it into other products, it is necessary to: 1. Even if plastics are mixed with other materials such as egg packs, they cannot be recycled due to differences in processing temperatures. 2. It is necessary to remove the metal cap and paper label attached to the PET bottle. Unless plastic bottles are crushed, there remain problems such as bulkiness and difficulty in using them.

Therefore, when trying to reuse such a PET bottle, when the PET bottle is collected from a general household, only the PET bottle is already separated, the metal cap or the paper label is removed, and the PET bottle is crushed. Is preferred.

However, if a heater or the like is used at home to heat and compress the PET bottle, there is a possibility of ignition, and it takes time and effort to remove the paper label from the PET bottle, so that the PET bottle can be separated and collected. Even so, it was extremely difficult to perform other processing at home.

Therefore, the present invention has been made to solve the above-mentioned problem, and a paper label attached to a plastic bottle can be easily removed even in a general household.
In addition, it is an object of the present invention to provide a plastic bottle processing apparatus which can be heated and compressed safely and is extremely effective in recycling plastic bottles.

[0008]

In order to achieve the above-mentioned object, the present invention comprises a heating mechanism 10 located at the bottom P2 of a plastic bottle P for heating the bottom P1 with hot water, and an upper part P1 of the plastic bottle P. And a compression mechanism 20 for compressing the upper part P1 with the bottom part P2.

Further, the heating mechanism 10 and the compression mechanism 20
A heater 12 housed inside the container 1 and provided inside the heating mechanism 10 is provided so as to obtain hot water of 90 ° C. or more.

Further, the compression mechanism 20 comprises a rotary long screw 25 linked to the motor 21 and a pressing body 30 provided on the rotary long screw 25 so as to be vertically movable.

The pressing body 30 is screwed to the rotary long screw 25 and is movable up and down, and the movable body 31 is detachably provided on the movable board 31 to connect and fix the upper part P1 of the PET bottle P. And the lid 32 to be used as means for solving the problem.

[0012]

According to the present invention, the bottom part P2 of the plastic bottle P is heated by the hot water of the heating mechanism 10, and in this state, the compression mechanism 20 is heated.
Compresses the upper part P1 of the PET bottle P into the bottom part P2. Then, the bottom of the PET bottle P gradually shrinks, and the paper label attached to the surface of the PET bottle P comes off.

The container 1 covers the heating mechanism 10 and the compression mechanism 20, and the hot water of the heating mechanism 10
0 The heater inside heats more than 90 degrees Celsius.

Further, when the pressing body 30 is lowered along the rotary long screw 25 which is rotated by the drive of the motor 21,
The upper part P1 of the PET bottle P is compressed at the bottom part P2.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

The basic structure of the present invention comprises a heating mechanism 10 for heating the bottom P2 of the plastic bottle P with hot water, and a compression mechanism 20 for compressing the top P1 of the plastic bottle P with the bottom P2. At this time, the heating mechanism 10 and the compression mechanism 20
Means that the heating mechanism 10 and the compression mechanism 2 are housed in the container 1 through a partition 2 provided in the container 1.
0 is vertically separated (see FIG. 1).

In the illustrated heating mechanism 10, a heater 12 is provided inside a hot water tub 11 for storing hot water.
The setting is such that the temperature of the hot water is at least 90 degrees Celsius or higher. At this time, it is also possible to use steam at 90 degrees Celsius or more instead of the hot water in the hot water tub 11. In addition, a support protrusion 13 is provided in the inside of the water reservoir 11 so as to press against the central portion of the bottom portion P2 in order to increase the compression efficiency of the PET bottle P. In addition, the heating mechanism 10 can be mounted on a resource collection vehicle by using the cooling water of the engine.

The compression mechanism 20 is composed of a long screw 25 linked to the motor 21 and a pressing body 30 provided on the long screw 25 so as to be vertically movable. Rotating long screw 2 shown
5 rotates forward and backward through a worm gear 22 linked to a motor 21 and spur gears 23 and 24 linked to the worm gear 22. The compression mechanism 20 can be arbitrarily selected as the other compression mechanism 20, such as a mechanism that manually rotates the rotary screw 25 instead of the motor 21 or a mechanism that moves the pressing body 30 up and down by leverage. is there.

On the other hand, the pressing body 30 is screwed to the rotary long screw 25 and is movable vertically (see FIG. 2).
And is provided detachably on the movable board 31,
A lid 32 (see FIG. 3) for connecting and fixing the upper part P1 of the PET bottle P. The lid 32 is particularly provided with a connecting portion 33 that fits into a screw at the mouth of the plastic bottle P, thereby making it very easy to attach and detach the plastic bottle P. Further, a handle 34 protrudes from the upper portion of the lid 32 so that the PET bottle P which is compressed toward the heating mechanism 10 and is in a heated state can be taken out of the heating mechanism 10 without directly touching it. It has become. In the illustrated example, the locking piece 35 of the lid 32 is
The detaching means for engaging with the fitting concave portion 36 is adopted. Reference numeral 37 in the figure is a screw hole for screwing the rotary long screw 25.

[0020]

According to the present invention, the above-mentioned configuration achieves the original object.

That is, the PET bottle P can be heated and compressed safely even in ordinary households. Moreover, in this heating and compressing step, the paper label attached to the surface of the PET bottle P is easily detached, which is very preferable as promoting the reuse of the PET bottle P resources.

Further, the heating and compression can be always performed in a stable state. As a result, the apparatus of the present invention can be compressed into a similar shape no matter who operates the apparatus, which is convenient for the collection, transportation, and reuse steps.

Further, since the lid 32 is provided detachably on the movable board 31 of the pressing body 30 and connects and fixes the upper part P1 of the plastic bottle P, the plastic bottle P can be easily taken in and out, and the processing can be performed. The work is simple and safe use is possible even in ordinary households.

As described above, according to the present invention, the paper label attached to the PET bottle can be easily removed even in a general household, and the PET bottle can be safely heated and compressed. It has various industrially beneficial effects such as being extremely effective.
