[0009]

An empty can or a plastic bottle is introduced between one metal roll and the other metal roll, and the crushing plate and the block-shaped claw provided on one metal roll are close to the surface of the other metal roll. The other block-shaped claw body provided on the other metal roll is close to and located between the crushed plate provided on the one metal roll and the claw body. In other words, each of the crushing plate and the claw body approaches the mating metal roll surface alternately with the mating claw body. Therefore, the empty can or the plastic bottle is crushed by the wide crushing plate and the both claws while being drawn into both the claws, and is discharged through both metal rolls.

[0010] In addition, by arranging each of the crushing plate and the claw body provided on the metal roll in a chevron shape over the entire width of the roll, particularly in the case of a PET bottle, it may escape when hitting the claw body. The PET bottle is pressed down in a state inclined with respect to the axial direction of the roll, so that the PET bottle can be easily pulled into the roll when crushed, and can be easily crushed in a short time.

In particular, the other block-shaped claw body and the block-shaped claw body for preventing the container from escaping are alternately provided at an interval slightly larger than the interval corresponding to the crushing plate provided in the circumferential direction of one of the metal rolls. In this case, even if the PET bottle tries to escape from the claw body, the PET bottle can be effectively crushed while being securely caught by the corners of the escape prevention block-shaped claw body arranged in a different direction from the claw body it can.

When each of the crushed plate, the claw body, and the block-shaped claw body for preventing escape of the container provided on the metal roll are disposed in a mountain shape over the entire width of the roll, there is almost no escape of the PET bottle, which is more effective. Can be crushed. Also, the case where the crushing plate is provided on both of the metal rolls is suitable for the case where the crushing machine is enlarged, and it is needless to say that empty cans and PET bottles can be crushed alternately with both crushing plates. Various types of containers can be crushed, and can be crushed alternately not only by the crushing plate provided on one side but also by the crushing plates provided on both sides, so that durability can be increased and long-term use can be endured.

Good to do. By arranging the crushing plate 6 in a chevron shape, the plastic bottle put between the metal rolls 1 and 2 is captured by the crushing plate 6 while being captured in an inclined state with respect to the roll axis together with a claw body 8 described later. It will be crushed efficiently. It is easier to catch the PET bottle without escaping than to catch the PET bottle in parallel with the roll axis.

Reference numeral 7 denotes a block-shaped claw body provided before and after the crushing plate 6 of one of the metal rolls 1 and is provided at predetermined intervals in the roll width direction. The crushed plate 6 and the block-shaped claw 7 are formed to have the same height or the same thickness, and the other block-shaped provided on the other metal roll 2 is provided between the crushed plate 6 and the block-shaped claw 7. An interval is provided so that the claw body 8 is located.

When the crushing plate 6 is disposed in the shape of a mountain, the block-shaped claw 7 is also disposed in the shape of a mountain. In this embodiment, a case is shown in which each of the block-shaped claw body 7 and the crushing plate 6 is arranged in a mountain shape. The reason why the claw body 7 is formed into a block shape is to make it easy to catch the container at the corner and to endure repeated use in terms of strength.

On the other metal roll 2, the other block-shaped claw body 8 is provided along the circumferential direction at a slightly wider interval than the space corresponding to the crushing plate 6. When you hit 8, you may run away without getting caught. In order to eliminate the phenomenon of escape, the other metal roll 2 is provided with the other block-shaped claw bodies 8 and the block-shaped claw bodies 9 for preventing escape of the container alternately. It is important that the escape-preventing block-shaped claw bodies 9 are installed at a wider interval than the claw bodies 7 and 8 and oriented in a direction different from the orientation of the claw bodies 7 and 8. In this example, when each of the crushing plate 6 and the claw members 7 and 8 are oriented in a chevron shape,
The orientation direction of the claw members 7 and 8 is oriented along the chevron direction, while the orientation direction of the escape-preventing block-shaped claw body 9 is oriented in a direction parallel to the roll axis.

Although not shown, crushing plates 6 may be provided alternately on both of the metal rolls 1 and 2. That is, the other metal roll 2 is provided with another crushed plate 8 and the other block-shaped claw body 8 similar to the crushed plate 6 and the claw body 7 provided on the one metal roll 1, and both metal rolls 1, 2
