Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a method for easily compressing and reducing the weight of used PET bottles in general households when discarding the used PET bottles. Not only in the field of waste treatment,
It can be widely used in the field of recycling PET bottles.

2. Description of the Related Art At present, used beverage PET bottles are discarded and then recycled.
It is necessary to reduce the volume by crushing at the time of disposal for transportation, accumulation and storage before processing. Conventionally, in general, used PET bottles are collected as they are, then reduced at a processing plant by a large-scale crushing and crushing machine, and then recycled. However, in each municipality, the transportation and storage work was extremely inefficient even if the waste was separated and disposed. For this reason, in each household, it is being promoted to reduce the weight by crushing at the time of disposal. Since it is difficult to crush the opening side and the bottom side, they remain as they are, and the effect of weight reduction was not expected.

[Problems to be Solved by the Invention] Conventionally, reducing the weight of plastic bottles performed in ordinary households only involves crushing the sides, and the effect of the weight reduction has not been improved. In order to crush and increase the weight loss effect, it is effective to press and crush from the vertical direction rather than the side (horizontal) direction, but to press and compress from the vertical direction, simply pressing it requires a strong pressing force Therefore, it is difficult to easily implement the method using tools used at home. The present invention is completely different from the conventional means of crushing the side direction, in which the pressing direction is set to the vertical direction, the entire PET bottle is first twisted, and thereafter, the PET bottle is pressed down directly and pressurized from the vertical direction, and the twisted pet is pressed. The bottle is compressed vertically to minimize weight loss.

[Means for solving the problems]
Turn the PET bottle upside down, push and fix, push and twist,
Further, the action of pressing and crushing and compressing is performed continuously by a consistent operation of just pressing, by twisting the entire PET bottle fixed upside down first, and then pressing it directly down from the vertical direction, It compresses to the maximum and reduces the weight. The first torsion can be easily twisted with a small force, and the application of the torsional force and the subsequent downward pressing force can be easily performed by pressing.

That is, according to the present invention, a bottom support having a plurality of piercing needles for fixing the opening surface of a bottle protruding from an upper surface thereof and an upper support having a vertical cylinder portion at the center are spaced by a plurality of columns. The lifting and lowering rotating body attached to a lifting guide which is slidably fitted to the support column and which moves up and down is provided with a rotation imparting projection in a through hole provided in the center portion and projects the upward cylindrical body. A cylindrical elevating operation shaft 7 provided with a handle 1 at the upper end is inserted into the elevating cylinder portion 4, and the rotation and elevating and lowering are inserted into the upwardly directed cylinder and the shaft hole of the elevating operation shaft. The free rotating body is provided with a rotating helical groove on the lower end side in which the rotation imparting protrusion is slidably fitted, and the lower end of the rotating body is provided with a plurality of piercing needles for fixing the bottom surface of the bottle on the lower surface. A pet port in which a presser is continuously provided, and a spring is fitted to a rotating body in the upward cylinder. A Le compressor.

[Operation] The operation will be described with reference to FIGS. 1, 2 and 3. The upper handle 1 is raised to the top as shown in FIG. 1, and the PET bottle 20 is set between the bottle holder 10 and the bottom support 2 in an inverted state as shown by the dotted line. At this time, the rotation imparting projection 16 provided on the rotation imparting body 13 that freely moves up and down fits into the lowermost end of the rotating spiral groove 9 of the rotating body 8. Thereafter, when the handle 1 is slightly pressed down, the plastic bottle 20 is compressed with the spring 18 compressed.
The opening surface is fixed by a needle 5 on the upper surface of the bottom support 2, and the bottom surface is fixed by a needle 11 on the lower surface of the bottle holder 10. In this state, when the handle 1 is further depressed, the rotating body 8 rotates and descends while rotating due to sliding of the rotation imparting projection 16 fitted in the rotating spiral groove 9 in the groove. The directly-connected bottle holder 10 descends while rotating, and a rotational force is applied to the bottom surface of the plastic bottle 20 fixed by the puncture needle 11 to apply a torsional force. Therefore,
As the handle 1 descends, the rotation of the rotating body 8 continues, the bottle holder 10 and the vertically rotating body 13 descend, and the entire PET bottle 19 is twisted as shown by the dotted line in FIG. On this occasion,
Since the handle 1 and the rotating body 8 are rotatably connected, the handle 1 does not rotate.

Thereafter, when the handle 1 continues to descend, the rotating body 8
Stops rotating, and as shown in FIG. 3, the bottle holder 10 and the rotation applying body 13 in the state as they are are lowered to compress the twisted PET bottle 20 to the maximum as shown by the dotted line. Thereafter, when the pushing force of the handle 1 is removed, the needles 5 and 11 are removed from the pet pottle 20 by the restoring force of the spring 18. After taking out the compressed PET bottle 20, when performing the next compression, pull up the handle 1,
The rotating body 8 rises by the reverse rotation by the rotation imparting projection 16, and at the same time, the bottle holder 10 also rises, restoring the state shown in FIG. 1.

[Embodiment] An embodiment shown in FIGS. 1, 2 and 3 will be described. The bottom support 2 having a plurality of needles 5 protruding from the upper surface for fixing the opening surface of the PET bottle 20 set upside down, and the upper support 3 having the elevating cylinder 4 in the center are connected to a plurality of columns 6. The main body is formed by fixing at intervals. A through hole 15 is provided in the center of the rotation applying body 13 which is connected to an elevating guide 14 which is freely slidably fitted to the support column 6 and which vertically moves up and down. An upwardly directed cylindrical body 12 is provided to protrude. A handle 1 is provided at the upper end of the elevating cylinder part 4, and a cylindrical elevating operation shaft 7 having a shaft hole 17 at a lower end side is inserted thereinto, and the rotating body 8 is inserted into the shaft hole 17 and the upward cylinder 12. Insert. The rotating body 8 is provided at its lower end with a rotating helical groove 9 into which the rotation imparting projection 16 is slidably fitted, and at the lower end thereof a plurality of needles 11 for fixing the bottom of the bottle projecting from the bottom. 10 and the upwardly facing cylindrical body 12
The spring 18 is fitted to the portion of the rotating body 8 inside. Therefore, when the rotating body 8 rotates, the bottle holder 10 rotates together with the rotating body 8, but the elevating operation shaft 7 separated from the upwardly directed cylindrical body 12 of the elevating rotation applying body 13 does not rotate.

As shown in FIG. 1, when the lifting operation shaft 7 is raised, the rotation imparting projection 16 provided on the rotation imparting body 13 which moves up and down but is fixed in the horizontal direction rotates the rotating body 8. The rotary body 8 and the bottle holder 10 do not fall down alone because they are fitted in the spiral groove 9 for use. When the handle 1 is depressed and the elevating operation shaft 7 is lowered, the bottle holder 10 presses the PET bottle 20, compresses the spring 18, and the needle 11 on the lower surface of the bottle holder 10 and the needle 5 on the upper surface of the bottom support 2 make the PET bottle. 20 is fixed. When the handle 1 is further depressed, the rotating body 8 and the bottle holder 10 are rotated by the sliding of the rotation imparting projection 16 fitted in the spiral groove 9 for rotation, and as shown in FIG.
A twisting force acts on. Thereafter, when the handle 1 is further depressed to lower the elevating operation shaft 7, a compressive force acts in a downward direction in a state where the rotation of the bottle holder 10 is stopped, and the PET bottle 20 is compressed to the maximum as shown in FIG. Can be reduced.
