とができる。In this device, the shaft is driven by the power given by the prime mover 15.
13 rotates, and gear 14 is fitted to shaft 13
The rotation torque is transmitted to 11, and the lower drum 2 rotates. Then, the rotational force is transmitted from the gear 10 to the gear 9 that meshes with the gear 10, and the upper drum 1 rotates. Therefore, the upper and lower drums 1 and 2 rotate in mutually opposite directions, and the upper and lower knives 3 and 4 fixed to the upper and lower drums 1 and 2 approach and engage once per one rotation of the drums 1 and 2.
The cycle of leaving will be repeated. Also,
The prime mover 15 controls the rotation speed according to a desired cutting length of the corrugated board by a signal system (not shown), and determines the feeding speed of the corrugated board and the rotation peripheral speed of the upper and lower knives 3 and 4 when cutting the corrugated board, that is, the upper and lower knives. The rotational speeds of the upper and lower drums 1 and 2 are controlled to accelerate and decelerate in order to equalize the speeds when the 3 and 4 are engaged. According to this structure of the rotary cutter, the corrugated board continuously fed by the conveyor is cut by the upper and lower knives 3 and 4, and the corrugated board cut into a desired length can be obtained.

る。Next, problems with the conventional device will be described. In this device, the cutting operation is performed according to all traveling speeds of the corrugated board ranging from low speed to high speed. As for cutting, the upper and lower knives 3 and 4 start engaging from one knife end as described above, and the engaging position moves axially with the rotation of the upper and lower drums 1 and 2 to reach the other knife end. It is performed by repeating the operation of leaving at the point of time. At this time, the upper and lower knives 3 and 4 undergo bending vibration in the direction in which the upper and lower knives 3 and 4 open due to the initial impact when the upper and lower knives 3 and 4 start to engage and start cutting. When the bending vibration cycle of the upper and lower drums 1 and 2 and the moving speed associated with the engagement of the upper and lower knives 3 and 4 are synchronized with each other, resonance occurs and a state in which the upper and lower knives 3 and 4 are not in contact with each other occurs. Therefore, in a certain cutting speed region, the knives 3 and 4 open to cause a phenomenon that the sharpness is deteriorated or cutting failure occurs.

Here, the difference between the inner diameters of the upper and lower drums 1 and 2 and the outer diameters of the upper and lower cylinders 17A and 17B, that is, the clearance, must be set appropriately in order to improve the vibration suppression effect described later, but as a rough guideline, it is several hundred. It is in the range of μm to several tens of mm. The upper and lower cylinders 17A and 17B are enclosed for the purpose of colliding with the inner surfaces of the drums in the hollow portions of the upper and lower drums 1 and 2, and the standard of the mass is 2 to 20% of the vibration equivalent mass of the drum system. It should be about.
本発明の基本的な構成は、上記の如き上下円筒17A,17B
の少なくともその一方をドラムに封入することにある。
なお、ここで円筒17A,17Bとドラム1,2との中空部に油等

支持される。In addition to this, if the following configuration is adopted as a support device for the cylinders 17A and 17B, it is technically possible to add a measure for preventing vibration only at the time of resonance, which has been cited as a conventional problem. 18A and 18B are cylindrical shafts formed at both ends of the cylinders 17A and 17B and having conical tips. 19A, 19B
Is a support member having an inverted conical concave portion that is in close contact with the conical portions of the cylindrical shaft portions 18A and 18B. The support members 19A and 19B are fixed to the cylinder rods 20A and 20B, respectively.
Are configured to be able to project and retract in the pressurizing cylinders 21A and 21B, respectively. The pressure cylinders 21A and 21B are rigidly supported by the frame 22.

として示した。With the same configuration, the upper and lower cylinders 17A and 17B can be supported from the side surfaces of the upper and lower drums 1 and 2 to the inner surfaces of the drums 1 and 2 in a non-contact state, and the cylinders 17A and 17B cannot be supported by the support members 19A and 19B. Allows the cylinders 17A and 17B to freely collide with the hollow portions of the drums 1 and 2 by the operation described later. That is, the cylinders 17A, 17
When B is supported on the inner surfaces of the drums 1 and 2 in a non-contact state, the internal pressure of the pressurizing cylinders 21A and 21B is increased and the cylinder rods 20A and 20B are projected so that the supporting members 19A and 19B are supported.

As a result, the cylinders 17A and 17B can be supported and fixed to the frame 22 system without contacting the inner surfaces of the upper and lower drums 1 and 2. Further, by reducing the internal pressure of the pressurizing cylinders 21A, 21B and submerging the cylinder rods 20A, 20B into the pressurizing cylinders 21A, 21B, the supporting members 19A, 19B move accordingly and the cylindrical shaft portions 18A, 18B. Further, the cylinders 17A and 17B are released so that the cylinders 17A and 17B can be freely moved. This state is shown in FIG. 2 as a partial view.

を行わせればよい。Now, in the device of the present embodiment configured as described above, with respect to the bending vibration of the upper and lower drums 1 and 2 caused by the initial impact caused by the cutting of the corrugated cardboard fed by the engagement of the upper and lower knives 3 and 4, The cylinders 17A and 17B, which are enclosed in the upper and lower drums 1 and 2 and are allowed to move freely, collide with the inner surfaces of the drums 1 and 2 so as to resist the vibrations and suppress the vibrations. That is,
At this time, since the cylinders 17A and 17B as mass elements are not particularly fixedly supported, the movement of the cylinders 17A and 17B cannot be followed due to the rapid movement accompanied by the vibration of the drums 1 and 2, and thus floats in the air. It collides with the inner surfaces of the drums 1 and 2. Therefore,
The cylinders 17A and 17B serve as so-called impact dampers. Further, when it is desired to expect the collision action of the cylinders 17A, 17B only at the time of resonance, which is a problem of the rotary cutter, the cylinder shaft device 18A, 18B is normally supported by the support members 19A, 19B by the cylinder support device as described above. Pressurize cylinder 21A, only in the speed range where you want to suppress vibration and keep it fixed.
It suffices to operate 21B and release the cylinders 17A and 17B to perform the above-mentioned collision action.
このようにドラム1,2の振動を円筒17A,17Bの衝突作用に
よって抑制すれば、ドラム1,2に固着されたナイフ3,4の
開きも抑制され、切味が劣化することもなく切断不良も
防止され、段ボールの切断品質を良好に維持できる。If the vibration of the drums 1 and 2 is suppressed by the collision action of the cylinders 17A and 17B in this way, the opening of the knives 3 and 4 fixed to the drums 1 and 2 is also suppressed, and the cutting quality does not deteriorate and the cutting failure occurs. Is also prevented and the cutting quality of the corrugated board can be maintained in good condition.

る。(Effects of the Invention) As described above in detail, according to the present invention, even when the drum vibrates, vibration is suppressed by the collision action of the cylinder enclosed inside, and as a result, opening of the knife can be suppressed, resulting in poor cutting. In addition, it is possible to expect great effects such as deterioration of sharpness can be prevented and cutting quality of corrugated board can be improved.
