満足できる。 In the above configuration, the unidirectional rotation transmission mechanism means a mechanism that transmits rotation to a rotated body in only one direction, and is usually referred to as a one-way clutch mechanism.

更に、本考案を、実施例を用いて、図面を参照
しながら説明する。 Further, the present invention will be explained using examples and with reference to the drawings.
第１図は、本考案に係る切断装置の一例を示す
概略構成図である。 FIG. 1 is a schematic diagram showing an example of a cutting device according to the present invention.
この切断装置は、大きくは、回転丸刃機構と、
被加工物取付機構とに分けられる。 This cutting device mainly consists of a rotating round blade mechanism,
It can be divided into workpiece attachment mechanism.

ある。 The rotating round blade mechanism is composed of a rotating round blade 1, an arm 2, an intermediate shaft 3, a first rotary drive motor 4, and drive transmission belts 5, 5'.
a first rotary drive motor 4, a drive transmission belt 5,
5' constitutes a drive system for the rotary round blade 1.
The rotational torque of the first rotary drive motor 4 is transmitted to the rotary round blade 1 via the drive transmission belts 5, 5', and the rotary round blade 1 rotates at a constant rotation speed. The arm 2 is swingably supported around the intermediate shaft 3 as a fulcrum. The arm 2 is then swung toward the workpiece 6 to press the rotary round blade 1 against the workpiece to cut the workpiece 6.

る。 The workpiece mounting mechanism is composed of a mounting shaft 7 that supports the workpiece 6, a one-way rotation transmission mechanism 8, a second rotation drive motor 9, and drive transmission belts 10, 10'. , a second rotary drive motor 9, and drive transmission belts 10, 10' constitute a drive system for the workpiece 6. The torque of the second rotation drive motor 9 is determined by the rotation transmission belt 10,
10' and is transmitted to the workpiece 6 via the one-way rotation transmission mechanism 8, and the workpiece 6 rotates at a constant number of rotations.
この場合、一方向回転伝導機構８は、回転丸刃

６が回転するように構成しなければならない。 In this case, the unidirectional rotational transmission mechanism 8 is configured to rotate the rotary round blade 1 in a co-rotation direction when the rotary round blade 1 is pressed against the workpiece 6 attached to a freely rotatable shaft, that is, opposite to the rotation direction of the rotary round blade 1. It must be constructed so that the workpiece 6 rotates in the rotational direction.
また、被加工物６の外周の周速度は回転丸刃１

ことが必要である。このような回転丸刃１と被加
工物６間の周速度条件は、例えば、上記駆動伝導

回転数Ｎより増速され、連れ回り回転数N1で回
転する。 In addition, the circumferential speed of the outer circumference of the workpiece 6 is the rotating round blade 1
It is necessary to set the rotation speed so that it is smaller than the circumferential speed. Such circumferential speed conditions between the rotary round blade 1 and the workpiece 6 can be easily obtained by known means, such as by appropriately setting the pulley ratios of the drive transmission belts 5, 5', 10, and 10'. be able to. Attach the workpiece 6 to the shaft 7 under such circumferential speed conditions, and use the arm 2 to move the rotary round blade 1 to the workpiece 6.
When pressed, the circumferential speed of the rotating round blade 1 is higher than the circumferential speed of the workpiece 6, so the workpiece 6 is moved by the rotating round blade 1 in a direction that increases the friction torque corresponding to the difference in peripheral speed. receive. At this time, the speed increase in the co-rotation direction becomes free due to the operation of the unidirectional rotation transmission mechanism, so the rotation speed of the workpiece 6 is increased from the driving rotation speed N, and the rotation speed of the workpiece 6 is increased to the co-rotation rotation speed N 1 . Rotate.

ままでは次第に被加工物６の回転数N1が減少し、
ついには、切断終了前に回転停止してしまう。 As cutting progresses due to co-rotation, the workpiece 6
The rotational speed N 1 increases as the diameter of the uncut portion of the workpiece 6 becomes smaller, but when cutting a large, unbalanced workpiece 6 using a conventional device, the uncut portion of the workpiece 6 becomes smaller. When the diameter becomes smaller than a certain value, the friction torque caused by the rotating round blade 1 will be applied to the workpiece 6.
The torque N1 of the workpiece 6 will gradually decrease if it continues as it is.
Eventually, the rotation will stop before the cutting is finished.
しかしながら、本考案に係る切断装置は、被加
工物６の回転数N1が、第２の回転駆動モータ９

ることになる。 However, in the cutting device according to the present invention, the rotation speed N 1 of the workpiece 6 is
When the drive rotation speed decreases to N, the rotational torque of the second rotational drive motor 9 increases to the one-way rotational transmission mechanism 8.
is transmitted to the mounting shaft 7, and the workpiece 6 can continue to rotate at the rotation speed N.
The rotary round blade 1 allows cutting to the end without leaving any uncut parts.
第２の回転駆動モータ９の回転トルクを一方向

荷が加わり好ましい切断ができないことがある。 Although it is possible to rotate the workpiece 6 to the end of cutting by directly transmitting the rotation torque of the second rotation drive motor 9 to the mounting shaft 7 without going through the unidirectional rotation transmission mechanism 8, this method In this case, it is impossible to cut the workpiece 6 while rotating with the workpiece 6, and an extra load is applied to the workpiece 6 and the rotary round blade 1, making it impossible to perform the desired cutting.
以上述べたように、回転丸刃１で被加工物を連

る。 As described above, the method of cutting while rotating the workpiece with the rotary round blade 1 reduces the load on the rotary round blade, and the cut surface of the workpiece can be finished well. Therefore, in the present invention, the workpiece is allowed to rotate freely during machining of the outer periphery of the workpiece (during high-speed co-rotation).
一方、回転バランスの悪い被加工物の場合、中

駆動させるようにしたものである。 On the other hand, in the case of a workpiece with poor rotational balance, the slippage between the rotary round blade and the rotary round blade becomes large near the center axis, and the rotation becomes impossible, making it impossible to cut. During machining (low-speed co-rotation), the workpiece is forcibly driven to the end.
本考案において、円筒状の被加工物は、例えば
RO膜が適用される。 In the present invention, the cylindrical workpiece is, for example,
RO membrane is applied.

きる。 The RO membrane is made into a cylindrical shape by wrapping an RO membrane 12 with adhesive around a central axis 11 called a central pipe, as shown in FIGS. 2A and 2B. As shown in Figure 3, in order to make it into a product,
It is necessary to cut both sides of the membrane to a certain size and to the final cut so that the cut surface is clean. If the membrane cannot be cut to the final length, the chips will not be able to be pulled out of the central pipe. In this case, the operator has to cut open the membrane with a cutter and remove it, which takes a lot of effort. Once the cutting is completed, the chips can be easily removed as shown in FIG.
｛考案の効果｝
本考案は、上記の構成、作用を有するため、次

果を奏する。 First, in a cutting device for a workpiece 6, which is equipped with a mounting shaft 7 that rotatably supports a cylindrical workpiece 6, and a rotary round blade 1 that can be pressed in a direction perpendicular to the mounting shaft, a workpiece 6 is cut. A circumferential speed setting means for setting the circumferential speed of the rotary round blade 6 to be smaller than the circumferential speed of the rotary round blade 1 is provided in the drive system of the rotary round blade or the drive system of the workpiece. Since the unidirectional rotation transmission mechanism 8 is interposed in the system, if the workpiece 6 is a product with good rotational balance, the load applied to the rotating round blade 1 is small.
Moreover, the cut surface of the workpiece is also effectively finished.
更に、被加工物６が回転バランスの悪い製品で

Due to the action of the one-way rotation transmission mechanism 8, the workpiece 6
Since the machine rotates reliably until the final stage of cutting, even heavy objects or workpieces with poor rotational balance can be cut without leaving any uncut parts.
また、被加工物６を積極回転せしめたため、高
価な回転丸刃１の破損が減少し寿命が延びた。 Furthermore, since the workpiece 6 is actively rotated, damage to the expensive rotary round blade 1 is reduced and its life is extended.
