Description

本発明は、シート状物を切断する切断装置および切断方法の技術に関する。   The present invention relates to a cutting device and a cutting method for cutting a sheet-like material.

従来から、互いに反対方向に回転する略円板状の上下刃を具備する切断装置によって、搬送されるシート状物（例えば、金属箔等）を切断することが行われている。
上下刃は、互いに所定の間隔だけ先端部をオーバーラップさせるとともに、互いに対向する上下刃の一端面の深さ方向（上下刃の回転軸方向）に所定の間隔だけクリアランスを形成することで、長寿命化できることが知られている。 2. Description of the Related Art Conventionally, a sheet-like object (for example, a metal foil or the like) to be conveyed is cut by a cutting device that includes substantially disk-shaped upper and lower blades that rotate in opposite directions.
The upper and lower blades are overlapped with each other at a predetermined interval, and a clearance is formed at a predetermined interval in the depth direction of one end face of the upper and lower blades facing each other (in the rotational axis direction of the upper and lower blades). It is known that the life can be extended.

上下刃が摩耗した場合、クリアランス量は摩耗部間の距離となる。つまり、上下刃の摩耗深さ（深さ方向における上下刃の摩耗量、つまり、摩耗部の深さ寸法）だけ、クリアランス量が変動する。従って、上下刃の摩耗が進んだ場合、クリアランス量が所定の範囲を超えてしまうため、上下刃を長寿命化できなくなってしまう。
このため、上下刃の摩耗深さを定期的に測定する必要がある。 When the upper and lower blades are worn, the clearance amount is the distance between the worn parts. That is, the clearance amount varies by the wear depth of the upper and lower blades (the wear amount of the upper and lower blades in the depth direction, that is, the depth dimension of the worn portion). Therefore, when the wear of the upper and lower blades progresses, the clearance amount exceeds the predetermined range, so that the life of the upper and lower blades cannot be extended.
For this reason, it is necessary to periodically measure the wear depth of the upper and lower blades.

特許文献１に開示される技術では、投光器、受光器、および摩耗量演算処理手段を用いて上下刃の水平方向の摩耗量（上下刃の摩耗深さ）を測定する。
投光器は、上下刃よりも搬送方向上流側または下流側に配置され、上下刃に向けて搬送方向（上下刃の径方向）に沿った光を照射する。受光器は、上下刃を挟んで投光器に対して対向配置され、投光器からの光を受光する。摩耗量演算処理手段は、受光器の受光量に基づいて上下刃の摩耗面積を算出し、摩耗面積から上下刃の水平方向の摩耗量を算出する。 In the technique disclosed in Patent Document 1, the amount of wear in the horizontal direction of the upper and lower blades (the wear depth of the upper and lower blades) is measured using a projector, a light receiver, and a wear amount calculation processing means.
The projector is disposed on the upstream side or the downstream side in the transport direction from the upper and lower blades, and irradiates light along the transport direction (the radial direction of the upper and lower blades) toward the upper and lower blades. The light receiver is disposed opposite to the projector with the upper and lower blades interposed therebetween, and receives light from the projector. The wear amount calculation processing means calculates the wear area of the upper and lower blades based on the received light amount of the light receiver, and calculates the wear amount in the horizontal direction of the upper and lower blades from the wear area.

特許文献１に開示される技術では、光を照射して上下刃の水平方向の摩耗量を測定する都合上、ハレーションが発生してしまい測定誤差が生じてしまう。
また、上下刃の径方向に沿って光を照射する構成であるため、先端部よりも径方向内側の一端面が削れてクレーター形状の摩耗部が形成された場合（図９に示す上下刃２０・５０参照）、その測定誤差がさらに大きくなってしまう。 In the technique disclosed in Patent Document 1, halation occurs and measurement error occurs due to the convenience of measuring the amount of wear in the horizontal direction of the upper and lower blades by irradiating light.
Moreover, since it is the structure which irradiates light along the radial direction of an upper-and-lower blade, when the end surface of radial direction inner side is cut | disconnected from the front-end | tip part, and the crater-shaped wear part is formed (up-and-down blade 20 shown in FIG. 9) (Refer to 50), the measurement error is further increased.

つまり、特許文献１に開示される技術では、上下刃の摩耗深さを精度よく測定できなかった。   In other words, the technique disclosed in Patent Document 1 cannot accurately measure the wear depth of the upper and lower blades.

Then, the “front-back direction of the cutting device 1” is defined with the direction toward the back side of the paper surface in FIG.

本実施形態のシート状物１１０は、一つの電池の正極用の金属箔および負極用の金属箔であるものとし、後方向から前方向に向かって搬送されるものとする。
なお、切断装置１の切断対象となるシート状物１１０は、本実施形態に限定されるものでなく、扁平状である物、例えば、紙やフィルム等を広く含むものである。 The sheet-like object 110 of this embodiment shall be the metal foil for positive electrodes and the metal foil for negative electrodes of one battery, and shall be conveyed from back to front.
Note that the sheet-like object 110 to be cut by the cutting device 1 is not limited to the present embodiment, and widely includes flat objects such as paper and films.

切断装置１は、上ユニット１０、下ユニット４０、一対の測定機構７０等を具備する。   The cutting device 1 includes an upper unit 10, a lower unit 40, a pair of measurement mechanisms 70, and the like.

上ユニット１０は、シート状物１１０を上面から切断するためのものである。上ユニット１０は、上刃２０、自転軸３１、複数の自転軸受３２、およびラップ調整機構３４を備える。   The upper unit 10 is for cutting the sheet-like object 110 from the upper surface. The upper unit 10 includes an upper blade 20, a rotation shaft 31, a plurality of rotation bearings 32, and a lap adjustment mechanism 34.

図２および図３に示すように、上刃２０は、略円板状に形成される矩形刃である。この場合、上刃２０の径方向外側の端部が先端部２１となる。上刃２０は、切断装置１の左端部に配置され、切断装置１を左方向から見たとき視認可能である。   As shown in FIGS. 2 and 3, the upper blade 20 is a rectangular blade formed in a substantially disc shape. In this case, the radially outer end of the upper blade 20 is the tip 21. The upper blade 20 is disposed at the left end of the cutting device 1 and is visible when the cutting device 1 is viewed from the left.

図１および図２に示すように、自転軸３１は、第一軸３１ａと第二軸３１ｂとを相対回転不能に連結することで構成され、上刃２０を回転可能に支持する。
第一軸３１ａは、後述する公転軸３５に収容され、自転駆動軸３３からの動力で回転する。
第二軸３１ｂは、その外周面に上刃２０が相対回転不能に取り付けられる。 As shown in FIGS. 1 and 2, the rotation shaft 31 is configured by connecting a first shaft 31 a and a second shaft 31 b so as not to be relatively rotatable, and supports the upper blade 20 so as to be rotatable.
The first shaft 31 a is accommodated in a revolving shaft 35 described later, and is rotated by power from the rotation drive shaft 33.
The upper shaft 20 is attached to the outer peripheral surface of the second shaft 31b so as not to be relatively rotatable.

各自転軸受３２は、それぞれ後述する公転軸３５に収容される。本実施形態の各自転軸受３２は、それぞれ図２における左端部、左右中途部、および右端部にて、自転軸３１（第一軸３１ａ）を回転可能に支持する。   Each rotation bearing 32 is accommodated in a revolution shaft 35 described later. Each rotation bearing 32 of the present embodiment rotatably supports the rotation shaft 31 (first shaft 31a) at the left end portion, the left and right halfway portion, and the right end portion in FIG.

ラップ調整機構３４は、公転軸３５および公転軸受３６を備える。   The lap adjustment mechanism 34 includes a revolution shaft 35 and a revolution bearing 36.

公転軸３５は、上刃２０の右方に配置される。公転軸３５には、自転軸３１および各自転軸受３２を収容可能な中空部分が形成される。   The revolution shaft 35 is disposed on the right side of the upper blade 20. The revolution shaft 35 is formed with a hollow portion that can accommodate the rotation shaft 31 and each rotation bearing 32.

公転軸受３６は、公転軸３５の左端部に配置され、公転軸３５を回転可能に支持する。本実施形態の公転軸受３６は、左右方向に沿って複数のころが設けられ、公転軸３５を左右方向にも移動可能に支持する。   The revolution bearing 36 is arrange | positioned at the left end part of the revolution shaft 35, and supports the revolution shaft 35 rotatably. The revolution bearing 36 of this embodiment is provided with a plurality of rollers along the left-right direction, and supports the revolution shaft 35 so as to be movable also in the left-right direction.

公転軸３５は、公転駆動軸３７に連結されて回転可能に構成される。公転軸３５の回転に伴って、自転軸３１および各自転軸受３２は、それぞれ一体的に回転する。   The revolution shaft 35 is connected to the revolution drive shaft 37 and is configured to be rotatable. As the revolution shaft 35 rotates, the rotation shaft 31 and each rotation bearing 32 rotate integrally.

公転軸３５は、自転軸３１を偏心させて支持する（図２に示す軸線Ｌ１１・Ｌ１２・Ｌ２１・Ｌ２２参照）。すなわち、図２および図３に示すように、自転軸３１の中心Ｐ１１は、左右方向から見たときに、上下方向および左右方向に所定の間隔だけ公転軸３５の中心Ｐ１２から離間している。
ラップ調整機構３４は、公転軸３５を回転させることで公転軸３５の中心Ｐ１２を基準に、上刃２０を旋回させる。このような旋回動作によって、上刃２０は、後述する下刃５０および各測定機構７０に対して相対的に上下方向に移動する（図３に点線で示す上刃２０参照）。 The revolution shaft 35 eccentrically supports the rotation shaft 31 (see axes L11, L12, L21, and L22 shown in FIG. 2). That is, as shown in FIGS. 2 and 3, the center P <b> 11 of the rotation shaft 31 is separated from the center P <b> 12 of the revolution shaft 35 by a predetermined interval in the up-down direction and the left-right direction when viewed from the left-right direction.
The lap adjustment mechanism 34 rotates the revolution shaft 35 to rotate the upper blade 20 with reference to the center P12 of the revolution shaft 35. By such a turning operation, the upper blade 20 moves in the vertical direction relative to the lower blade 50 and each measuring mechanism 70 described later (see the upper blade 20 indicated by a dotted line in FIG. 3).

なお、ラップ調整機構３４の構成は、上刃２０を下刃５０および各測定機構７０に対して上下方向に相対的に移動可能な構成であればよく、本実施形態に限定されるものでない。   The configuration of the lap adjustment mechanism 34 is not limited to the present embodiment as long as the upper blade 20 can be moved relative to the lower blade 50 and each measurement mechanism 70 in the vertical direction.

下ユニット４０は、シート状物１１０を下面から切断するためのものである。下ユニット４０は、クリアランス調整機構６８を備える点を除いて、上ユニット１０と同様に構成される。   The lower unit 40 is for cutting the sheet-like object 110 from the lower surface. The lower unit 40 is configured in the same manner as the upper unit 10 except that a clearance adjustment mechanism 68 is provided.

図４に示すように、下刃５０は、上刃２０の左方に位置するとともに、その先端部５１（上端部）が上刃２０の先端部２１（下端部）よりも上方に位置する。
つまり、上下刃２０・５０は、互いに先端部２１・５１が上下方向へ所定の間隔だけオーバーラップするとともに、左右方向に所定の間隔だけ離間して、一端面２２・５２の間にクリアランスが形成される。 As shown in FIG. 4, the lower blade 50 is located to the left of the upper blade 20, and the tip 51 (upper end) thereof is located above the tip 21 (lower end) of the upper blade 20.
That is, the upper and lower blades 20 and 50 have the tip portions 21 and 51 overlap each other by a predetermined interval in the vertical direction, and are spaced apart by a predetermined interval in the left and right direction to form a clearance between the one end surfaces 22 and 52. Is done.

本実施形態では、上刃２０の左側面と下刃５０の右側面とが、それぞれ互いに対向する上下刃２０・５０の一端面２２・５２となる。
また、本実施形態では、上下刃２０・５０の平面方向を高さ方向とし、上下刃２０・５０の厚み方向を深さ方向とする。
すなわち、本実施形態のように上下刃２０・５０が略円板状である場合には、上下方向が高さ方向となり、上下刃２０・５０の外径寸法ｒが、それぞれ上下刃２０・５０の高さ寸法となる。
また、左右方向が、互いに対向する上下刃２０・５０の一端面２２・５２の深さ方向となる。 In the present embodiment, the left side surface of the upper blade 20 and the right side surface of the lower blade 50 are the end surfaces 22 and 52 of the upper and lower blades 20 and 50 that face each other.
In the present embodiment, the planar direction of the upper and lower blades 20 and 50 is the height direction, and the thickness direction of the upper and lower blades 20 and 50 is the depth direction.
That is, when the upper and lower blades 20 and 50 are substantially disk-shaped as in the present embodiment, the vertical direction is the height direction, and the outer diameter r of the upper and lower blades 20 and 50 is the upper and lower blades 20 and 50, respectively. It becomes the height dimension.
Further, the left-right direction is the depth direction of the one end faces 22, 52 of the upper and lower blades 20, 50 facing each other.

以下では、上下刃２０・５０のクリアランスの長さ、つまり、左右方向における各一端面２２・５２の距離を「クリアランス量Ｃ」と表記する。
また、上下刃２０・５０のオーバーラップの度合い、つまり、上下方向における上刃２０の先端部２１から下刃５０の先端部５１までの距離を「オーバーラップ量Ｄ」と表記する。 Hereinafter, the length of the clearance between the upper and lower blades 20, 50, that is, the distance between the one end faces 22, 52 in the left-right direction will be referred to as “clearance amount C”.
Further, the degree of overlap of the upper and lower blades 20, 50, that is, the distance from the tip portion 21 of the upper blade 20 to the tip portion 51 of the lower blade 50 in the vertical direction is expressed as “overlap amount D”.

クリアランス量Ｃおよびオーバーラップ量Ｄは、それぞれシート状物１１０の厚み（上下方向の幅）等に基づいて、所定の範囲内に設定される。
クリアランス量Ｃおよびオーバーラップ量Ｄを設定した状態で、図１および図２に示すように、切断装置１は、各自転駆動軸３３・６３により各自転軸３１・６１を回転させることで、上下刃２０・５０を互いに反対方向に回転させる。この状態で上下刃２０・５０に向けて、シート状物１１０を搬送して切断する（図６参照）。 The clearance amount C and the overlap amount D are set within a predetermined range based on the thickness (width in the vertical direction) of the sheet-like material 110, respectively.
In the state where the clearance amount C and the overlap amount D are set, as shown in FIGS. 1 and 2, the cutting device 1 rotates the rotation shafts 31 and 61 by the rotation drive shafts 33 and 63 so as to move up and down. The blades 20 and 50 are rotated in opposite directions. In this state, the sheet-like object 110 is conveyed and cut toward the upper and lower blades 20 and 50 (see FIG. 6).

これにより、切断装置１は、シート状物１１０の切断時に上下刃２０・５０の接触を防止して、上下刃２０・５０を長寿命化させている。   Thereby, the cutting device 1 prevents the upper and lower blades 20 and 50 from coming into contact with each other when the sheet-like material 110 is cut, thereby extending the life of the upper and lower blades 20 and 50.

このように、上下刃２０・５０は、シート状物１１０を切断する一対の刃具として機能する。
また、各ラップ調整機構３４・６４は、上下刃２０・５０を旋回させる一対の偏心旋回手段として機能する。 Thus, the upper and lower blades 20 and 50 function as a pair of cutting tools for cutting the sheet-like object 110.
The lap adjusting mechanisms 34 and 64 function as a pair of eccentric turning means for turning the upper and lower blades 20 and 50.

クリアランス調整機構６８は、回転可能な端面調整軸６９を備える。   The clearance adjustment mechanism 68 includes a rotatable end surface adjustment shaft 69.

端面調整軸６９は、回転運動を直進運動に変換する変換機構等を介して下ユニット４０の公転軸６５に連結され、回転することで下ユニット４０の公転軸６５を左右方向に移動させる。この移動に伴って下ユニット４０の自転軸６１および各自転軸受６２等が左右方向へ移動する。
これにより、切断装置１は、下刃５０を上刃２０に対して相対的に左右方向へ移動させ、クリアランス量Ｃを調整する。 The end surface adjustment shaft 69 is connected to the revolution shaft 65 of the lower unit 40 via a conversion mechanism or the like that converts rotational motion into straight motion, and moves to move the revolution shaft 65 of the lower unit 40 in the left-right direction. Along with this movement, the rotation shaft 61 and each rotation bearing 62 of the lower unit 40 move in the left-right direction.
Thereby, the cutting device 1 moves the lower blade 50 in the left-right direction relative to the upper blade 20 to adjust the clearance amount C.

本実施形態のように、クリアランス調整機構６８が下ユニット４０だけに備えられる構成である場合、上ユニット１０の公転軸受３６は、公転軸３５を回転可能に支持すればよく、必ずしも左右方向に移動可能に支持する必要はない。   When the clearance adjustment mechanism 68 is provided only in the lower unit 40 as in the present embodiment, the revolution bearing 36 of the upper unit 10 only needs to support the revolution shaft 35 in a rotatable manner and does not necessarily move in the left-right direction. There is no need to support it as much as possible.

測定手段としての各測定機構７０は、それぞれ各一端面２２・５２までの距離を左右方向から測定するものである。各測定機構７０は、それぞれ上刃２０の左方および下刃５０の右方に配置される。   Each measuring mechanism 70 as a measuring means measures the distance to each one end surface 22 and 52 from the left-right direction. Each measuring mechanism 70 is disposed on the left side of the upper blade 20 and on the right side of the lower blade 50, respectively.

本実施形態の各測定機構７０には、それぞれ左右方向に沿って波長の異なる複数のレーザを照射する分光干渉方式のレーザセンサが用いられる。この場合、各測定機構７０は、それぞれ各一端面２２・５２に当たって跳ね返るレーザの波長に基づいて、各一端面２２・５２までの距離を測定する。
なお、各測定機構７０の構成は、本実施形態に限定されるものでない。 Each measurement mechanism 70 of the present embodiment uses a spectral interference type laser sensor that irradiates a plurality of lasers having different wavelengths along the left-right direction. In this case, each measuring mechanism 70 measures the distance to each end surface 22, 52 based on the wavelength of the laser that bounces off each end surface 22, 52.
The configuration of each measurement mechanism 70 is not limited to this embodiment.

次に、切断装置１が用いられて行われる切断方法について説明する。   Next, a cutting method performed using the cutting device 1 will be described.

切断装置１は、図５に示すように、切断工程Ｓ１、測定工程Ｓ２、および調整工程Ｓ３を行う。   As shown in FIG. 5, the cutting apparatus 1 performs a cutting step S1, a measuring step S2, and an adjusting step S3.

図６に示すように、切断装置１は、切断工程Ｓ１において、上下刃２０・５０を互いに反対方向に回転させて、シート状物１１０を切断する。このとき、切断装置１は、上下刃２０・５０を旋回させない。
切断工程Ｓ１を行うことで、上下刃２０・５０は摩耗する。 As shown in FIG. 6, the cutting device 1 cuts the sheet-like object 110 by rotating the upper and lower blades 20 and 50 in opposite directions in the cutting step S1. At this time, the cutting device 1 does not turn the upper and lower blades 20 and 50.
By performing the cutting step S1, the upper and lower blades 20, 50 are worn.

図７および図８に示すように、各一端面２２・５２は、それぞれ摩耗している部分が各摩耗部２３・５３として形成されるとともに、摩耗していない部分が各非摩耗部２４・５４として形成される。   As shown in FIGS. 7 and 8, each end surface 22, 52 has a worn portion formed as each wear portion 23, 53, and a non-wear portion has each non-wear portion 24, 54. Formed as.

各摩耗部２３・５３の形状は、それぞれ切断条件等によって異なるものとなる。各摩耗部２３・５３の形状としては、例えば、切欠形状およびクレーター形状等がある。   The shapes of the wear parts 23 and 53 are different depending on cutting conditions and the like. Examples of the shape of each of the wear parts 23 and 53 include a notch shape and a crater shape.

図７に示すように、切欠形状の各摩耗部２３・５３は、それぞれ上下刃２０・５０の先端部２１・５１から中心Ｐ１１・Ｐ２１側に向けて、上下方向に所定の長さだけ削れる（摩耗する）ことで形成される。   As shown in FIG. 7, the respective wear parts 23 and 53 having a notch shape are scraped by a predetermined length in the vertical direction from the tip parts 21 and 51 of the upper and lower blades 20 and 50 toward the centers P11 and P21, respectively. Formed by wear).

図８に示すように、クレーター形状の各摩耗部２３・５３は、それぞれ上下刃２０・５０の先端部２１・５１よりも中心Ｐ１１・Ｐ２１側において、各一端面２２・５２が左右方向に窪む（摩耗する）ことで形成される。   As shown in FIG. 8, the crater-shaped wear parts 23 and 53 are recessed in the left and right directions on the center P11 and P21 side from the tip parts 21 and 51 of the upper and lower blades 20 and 50, respectively. It is formed by wearing (wearing).

図７および図８に示すように、各摩耗部２３・５３は、それぞれその形状に関わらず、上下方向に沿って平らな平坦面２３ａ・５３ａを有する。各平坦面２３ａ・５３ａは、それぞれ各摩耗部２３・５３において最も摩耗している部分である。   As shown in FIGS. 7 and 8, the wear parts 23 and 53 have flat surfaces 23 a and 53 a that are flat in the vertical direction regardless of the shape of the wear parts 23 and 53. The flat surfaces 23a and 53a are the most worn portions in the wear portions 23 and 53, respectively.

また、各摩耗部２３・５３の形状に関わらず、各一端面２２・５２においては、各非摩耗部２４・５４の先端部２４ａ・５４ａよりも、上下刃２０・５０の先端部２１・５１側が、全て各摩耗部２３・５３となる。
従って、上下刃２０・５０の先端部２１・５１は、各摩耗部２３・５３の先端部である。 Regardless of the shape of the wear parts 23 and 53, the tip parts 21 and 51 of the upper and lower blades 20 and 50 are located at the one end faces 22 and 52 rather than the tip parts 24a and 54a of the non-wear parts 24 and 54, respectively. The sides are all the wear parts 23 and 53.
Accordingly, the tip portions 21 and 51 of the upper and lower blades 20 and 50 are the tip portions of the wear portions 23 and 53, respectively.

このような各摩耗部２３・５３が形成された場合、左右方向および上下方向における上下刃２０・５０の摩耗量は、以下のように規定される。   When such wear parts 23 and 53 are formed, the wear amount of the upper and lower blades 20 and 50 in the left and right direction and the up and down direction is defined as follows.

左右方向における上下刃２０・５０の摩耗量は、各摩耗部２３・５３の深さ寸法である。つまり、各非摩耗部２４・５４から各摩耗部２３・５３の平坦面２３ａ・５３ａまでの、左右方向における長さ寸法である。
以下では、左右方向における上下刃２０・５０の摩耗量を、「上下刃２０・５０の摩耗深さｄ」と表記する。 The amount of wear of the upper and lower blades 20 and 50 in the left-right direction is the depth dimension of each wear portion 23 and 53. That is, it is the length dimension in the left-right direction from the non-wear parts 24, 54 to the flat surfaces 23a, 53a of the wear parts 23, 53.
Hereinafter, the amount of wear of the upper and lower blades 20 and 50 in the left-right direction is referred to as “wear depth d of the upper and lower blades 20 and 50”.

上下方向における上下刃２０・５０の摩耗量は、各摩耗部２３・５３の高さ寸法（各摩耗部２３・５３の上端部から下端部までの長さ寸法）である。つまり、上下刃２０・５０の先端部２１・５１から各非摩耗部２４・５４の先端部２４ａ・５４ａまでの、上下方向における長さ寸法である。
以下では、上下方向における上下刃２０・５０の摩耗量を、「上下刃２０・５０の摩耗幅ｗ」と表記する。 The amount of wear of the upper and lower blades 20 and 50 in the vertical direction is the height dimension of each wear part 23 and 53 (the length dimension from the upper end to the lower end of each wear part 23 and 53). That is, it is a length dimension in the up-down direction from the tip portions 21 and 51 of the upper and lower blades 20 and 50 to the tip portions 24 a and 54 a of the non-wear portions 24 and 54.
In the following, the amount of wear of the upper and lower blades 20 and 50 in the vertical direction is referred to as “the wear width w of the upper and lower blades 20 and 50”.

図９に示すように、上下刃２０・５０が摩耗したとき、左右方向における各摩耗部２３・５３の平坦面２３ａ・５３ａ間の距離が、クリアランス量Ｃとなる。
つまり、上下刃２０・５０の摩耗深さｄの変化量がクリアランス量Ｃの変化量となる。 As shown in FIG. 9, when the upper and lower blades 20, 50 are worn, the distance between the flat surfaces 23 a, 53 a of the wear parts 23, 53 in the left-right direction is the clearance amount C.
That is, the change amount of the wear depth d of the upper and lower blades 20 and 50 becomes the change amount of the clearance amount C.

上下刃２０・５０は、再研磨したときに、その取代の分だけ外径寸法ｒが小さくなる。また、切断装置１は、上下刃２０・５０を所定の回数だけ再研磨したときに、新品の上下刃２０・５０に交換する。このとき、上下刃２０・５０の外径寸法ｒが大きくなる。   When the upper and lower blades 20 and 50 are re-polished, the outer diameter r becomes smaller by the amount of the machining allowance. The cutting device 1 replaces the upper and lower blades 20 and 50 with new ones when the upper and lower blades 20 and 50 are re-polished a predetermined number of times. At this time, the outer diameter r of the upper and lower blades 20 and 50 is increased.

この場合、図１０に示すように、切断装置１は、上下刃２０・５０の外径寸法ｒの変化量に応じて上下刃２０・５０を旋回させなければ、オーバーラップ量Ｄが所定の範囲を超えてしまう、あるいは、上下刃２０・５０がオーバーラップしなくなる可能性がある。
つまり、上下刃２０・５０の外径寸法ｒの変化量がオーバーラップ量Ｄの変化量となる。 In this case, as shown in FIG. 10, the cutting device 1 has an overlap amount D within a predetermined range unless the upper and lower blades 20 and 50 are turned according to the amount of change in the outer diameter r of the upper and lower blades 20 and 50. Or the upper and lower blades 20 and 50 may not overlap.
That is, the amount of change in the outer diameter r of the upper and lower blades 20 and 50 becomes the amount of change in the overlap amount D.

そこで、切断装置１は、図５に示すように、クリアランス量Ｃおよびオーバーラップ量Ｄが所定の範囲を超える前に、測定工程Ｓ２および調整工程Ｓ３を行い、クリアランス量Ｃおよびオーバーラップ量Ｄを調整する（図５に示すクリアランス量Ｃ＋Ｎ参照）。
例えば、コイル状に巻かれたシート状物１１０を巻き出しながら切断する場合、コイル状のシート状物１１０を交換するときに、測定工程Ｓ２および調整工程Ｓ３を行う。また、上下刃２０・５０の再研磨や交換も、シート状物１１０の交換時に行う。 Therefore, as shown in FIG. 5, the cutting device 1 performs the measurement step S2 and the adjustment step S3 before the clearance amount C and the overlap amount D exceed the predetermined range, and sets the clearance amount C and the overlap amount D. Adjust (see clearance amount C + N shown in FIG. 5).
For example, when cutting the coiled sheet 110 while unwinding, when the coiled sheet 110 is replaced, the measuring step S2 and the adjusting step S3 are performed. Further, the upper and lower blades 20 and 50 are re-polished and replaced when the sheet 110 is replaced.

なお、測定工程Ｓ２および調整工程Ｓ３における切断装置１の動作等は、各摩耗部２３・５３の形状に関わらず、全て同様である。このため、以下では、上下刃２０・５０には、図８に示すようなクレーター形状の各摩耗部２３・５３が形成されたものとして説明を行う。   In addition, operation | movement of the cutting device 1 in measurement process S2 and adjustment process S3 are all the same irrespective of the shape of each wear part 23 * 53. Therefore, in the following description, it is assumed that the upper and lower blades 20 and 50 are formed with crater-shaped wear parts 23 and 53 as shown in FIG.

測定工程Ｓ２は、調整工程Ｓ３の前に行われ、上下刃２０・５０の摩耗深さｄと外径寸法ｒと摩耗幅ｗとを測定する。   The measurement step S2 is performed before the adjustment step S3, and measures the wear depth d, the outer diameter r, and the wear width w of the upper and lower blades 20 and 50.

切断装置１は、測定工程Ｓ２において、上下刃２０・５０の回転を停止する。そして、図２および図３に示すように、各ラップ調整機構３４・６４の公転駆動軸３７・６７（図１参照）を回転させて、予め設定される所定の位相まで上下刃２０・５０を旋回させる。
これにより、切断装置１は、各一端面２２・５２を各測定機構７０が測定できない位置まで、上下刃２０・５０を旋回させる。 The cutting device 1 stops the rotation of the upper and lower blades 20 and 50 in the measurement step S2. 2 and 3, the revolving drive shafts 37 and 67 (see FIG. 1) of the respective lap adjustment mechanisms 34 and 64 are rotated to move the upper and lower blades 20 and 50 to a predetermined phase set in advance. Turn.
Thereby, the cutting device 1 rotates the upper and lower blades 20 and 50 to the position where each measuring mechanism 70 cannot measure the one end surfaces 22 and 52.

そして、切断装置１は、図３に示す矢印の方向の反対方向に上下刃２０・５０を旋回させ、上下刃２０・５０の先端部２１・５１から順に各測定機構７０によって測定する。   Then, the cutting device 1 rotates the upper and lower blades 20 and 50 in the direction opposite to the direction of the arrow shown in FIG. 3, and measures by each measuring mechanism 70 in order from the tip portions 21 and 51 of the upper and lower blades 20 and 50.

すなわち、各測定機構７０は、それぞれ各公転軸３５・６５の中心Ｐ１２・Ｐ２１を中心とした旋回軌跡Ｔ１・Ｔ２に沿って、各一端面２２・５２を測定する。
これにより、図１１に示すように、旋回量に対応する上下刃２０・５０の上下方向への移動量と、各測定機構７０から各一端面２２・５２までの距離とを測定する。 That is, each measuring mechanism 70 measures each end surface 22 and 52 along the turning trajectories T1 and T2 around the centers P12 and P21 of the revolution shafts 35 and 65, respectively.
As a result, as shown in FIG. 11, the amount of vertical movement of the upper and lower blades 20, 50 corresponding to the turning amount and the distance from each measuring mechanism 70 to each end face 22, 52 are measured.

なお、切断装置１は、上下刃２０・５０の中心Ｐ１１・Ｐ２１側から順に測定しても構わない。   In addition, the cutting device 1 may measure in order from the center P11 / P21 side of the upper and lower blades 20/50.

各測定機構７０による測定値は、各測定機構７０のサンプリング周期および上下刃２０・５０の旋回速度に応じた間隔毎に得られる（図１１に示す点参照）。   The measurement value by each measuring mechanism 70 is obtained at intervals corresponding to the sampling period of each measuring mechanism 70 and the turning speed of the upper and lower blades 20 and 50 (see the points shown in FIG. 11).

上下刃２０・５０の移動量を縦軸、各測定機構７０の測定値を横軸にとり、各測定機構７０の測定値を縦軸に沿って順番に繋いだ場合、その形状は、各摩耗部２３・５３の形状に沿ったものとなる（図１１に示す符号Ｆ参照）。   When the amount of movement of the upper and lower blades 20 and 50 is taken on the vertical axis, the measured value of each measuring mechanism 70 is taken on the horizontal axis, and the measured value of each measuring mechanism 70 is connected in order along the vertical axis, the shape of each of the worn parts 23 and 53 (see symbol F shown in FIG. 11).

すなわち、各摩耗部２３・５３を測定した部分では、各測定機構７０の測定値が変動するため、その変動度合いに応じて各測定機構７０の測定値が斜めに繋がる。
また、各非摩耗部２４・５４を測定した部分では、各測定機構７０の測定値が一定となるため、各測定機構７０の測定値が直線で繋がる。 That is, since the measured value of each measuring mechanism 70 fluctuates in the portion where each of the wear parts 23 and 53 is measured, the measured value of each measuring mechanism 70 is connected obliquely according to the degree of variation.
Moreover, in the part which measured each non-wear part 24 * 54, since the measured value of each measuring mechanism 70 becomes fixed, the measured value of each measuring mechanism 70 is connected with a straight line.

このように、各測定機構７０の測定値は、上下方向に沿った各一端面２２・５２の深さの変位量となる。   As described above, the measurement value of each measurement mechanism 70 is the displacement amount of the depth of each end face 22, 52 along the vertical direction.

以上のように、切断装置１は、各測定機構７０と上下刃２０・５０とを上下方向に沿って相対的に移動させるとともに、各測定機構７０によって各一端面２２・５２を測定することで、上下方向に沿って各一端面２２・５２の深さの変位量を測定する。
また、切断方法では、各測定機構７０と上下刃２０・５０とを上下方向に沿って相対的に移動させるとともに、各測定機構７０によって各一端面２２・５２を測定することで、上下方向に沿って各一端面２２・５２の深さの変位量を測定する測定工程Ｓ２を行う。 As described above, the cutting device 1 relatively moves the measuring mechanisms 70 and the upper and lower blades 20 and 50 along the vertical direction, and measures the one end faces 22 and 52 by the measuring mechanisms 70. Then, the amount of displacement of the depths of the one end faces 22 and 52 along the vertical direction is measured.
Further, in the cutting method, each measuring mechanism 70 and the upper and lower blades 20 and 50 are relatively moved along the vertical direction, and each end surface 22 and 52 is measured by each measuring mechanism 70 so that the vertical direction is measured. A measuring step S2 for measuring the amount of displacement of the depths of the one end faces 22 and 52 is performed.

ここで、各測定機構７０の測定値は、左右方向から各一端面２２・５２を測定した結果である。
このため、切断装置１は、図８に示すようなクレーター形状の各摩耗部２３・５３が形成された場合でも、各一端面２２・５２までの距離を確実に測定できる。つまり、各一端面２２・５２の深さの変位量を確実に測定できる。 Here, the measurement value of each measurement mechanism 70 is the result of measuring each end surface 22 and 52 from the left-right direction.
For this reason, the cutting device 1 can reliably measure the distances to the one end faces 22 and 52 even when the crater-shaped wear parts 23 and 53 as shown in FIG. 8 are formed. That is, the displacement amount of the depth of each one end surface 22 * 52 can be measured reliably.

切断装置１は、各一端面２２・５２の深さの変位量の測定結果から、各測定機構７０の測定値と上下刃２０・５０の移動量とを選択的に取得する。   The cutting device 1 selectively acquires the measurement value of each measurement mechanism 70 and the movement amount of the upper and lower blades 20, 50 from the measurement result of the displacement amount of the depth of each one end face 22, 52.

本実施形態の切断装置１は、各測定機構７０の測定値として、各非摩耗部２４・５４までの距離ｘ０と、各摩耗部２３・５３までの距離ｘ１との測定結果を取得する。   The cutting device 1 of this embodiment acquires the measurement result of the distance x0 to each non-wear part 24 * 54 and the distance x1 to each wear part 23 * 53 as a measured value of each measurement mechanism 70. FIG.

各非摩耗部２４・５４までの距離ｘ０は、各摩耗部２３・５３の測定を終えて値が一定となったときの、各測定機構７０の測定値である。   The distance x0 to each non-wear part 24 * 54 is a measurement value of each measurement mechanism 70 when the measurement of each wear part 23 * 53 is finished and the value becomes constant.

各摩耗部２３・５３までの距離ｘ１は、各摩耗部２３・５３の平坦面２３ａ・５３ａを測定したときの、各測定機構７０の測定値である。
各摩耗部２３・５３を測定しているとき、各測定機構７０の測定値は変動するが、各摩耗部２３・５３の平坦面２３ａ・５３ａを測定しているときだけ、各測定機構７０の測定値が一定となる。切断装置１は、このときの各測定機構７０の測定値を各摩耗部２３・５３までの距離ｘ１として取得する。 The distance x1 to each wear part 23/53 is a measured value of each measurement mechanism 70 when the flat surfaces 23a / 53a of each wear part 23/53 are measured.
When the wear parts 23 and 53 are measured, the measurement values of the measurement mechanisms 70 change, but only when the flat surfaces 23a and 53a of the wear parts 23 and 53 are measured. The measured value becomes constant. The cutting device 1 acquires the measurement value of each measurement mechanism 70 at this time as the distance x1 to each wear part 23/53.

例えば、上下刃２０・５０の摩耗深さｄが変動した場合、その変動量に応じて各摩耗部２３・５３までの距離ｘ１も変動する。
つまり、各非摩耗部２４・５４および各摩耗部２３・５３までの距離ｘ０・ｘ１の差は、上下刃２０・５０の摩耗深さｄに対応する。 For example, when the wear depth d of the upper and lower blades 20 and 50 changes, the distance x1 to each wear part 23 and 53 also changes according to the amount of change.
That is, the difference between the distances x0 and x1 to the non-wear parts 24 and 54 and the wear parts 23 and 53 corresponds to the wear depth d of the upper and lower blades 20 and 50.

本実施形態の切断装置１は、上下刃２０・５０の移動量として、上下刃２０・５０の先端部２１・５１までの移動量ｙ０と、各非摩耗部２４・５４の先端部２４ａ・５４ａまでの移動量ｙ１との測定結果を取得する。   In the cutting device 1 of the present embodiment, as the movement amount of the upper and lower blades 20 and 50, the movement amount y0 to the tip portions 21 and 51 of the upper and lower blades 20 and 50, and the tip portions 24a and 54a of the non-wear portions 24 and 54, respectively. The measurement result with the movement amount y1 is acquired.

上下刃２０・５０の先端部２１・５１までの移動量ｙ０は、最初に各測定機構７０が各一端面２２・５２を測定したときの、上下刃２０・５０の移動量である。   The amount of movement y0 of the upper and lower blades 20 and 50 to the tip portions 21 and 51 is the amount of movement of the upper and lower blades 20 and 50 when each measuring mechanism 70 first measures the one end surfaces 22 and 52.

例えば、上下刃２０・５０の外径寸法ｒが変動した場合、その変動量に応じて、上下刃２０・５０の先端部２１・５１を測定するまでの、上下刃２０・５０の旋回量が変動する。つまり、上下刃２０・５０の先端部２１・５１までの移動量ｙ０も上下刃２０・５０の外径寸法ｒに応じて変動する。
つまり、上下刃２０・５０の先端部２１・５１までの移動量ｙ０は、上下刃２０・５０の外径寸法ｒに対応する。 For example, when the outer diameter r of the upper and lower blades 20 and 50 changes, the amount of turning of the upper and lower blades 20 and 50 until the tip portions 21 and 51 of the upper and lower blades 20 and 50 are measured according to the amount of change. fluctuate. That is, the amount of movement y0 of the upper and lower blades 20 and 50 to the tip portions 21 and 51 also varies depending on the outer diameter r of the upper and lower blades 20 and 50.
That is, the movement amount y0 of the upper and lower blades 20 and 50 to the tip portions 21 and 51 corresponds to the outer diameter r of the upper and lower blades 20 and 50.

各非摩耗部２４・５４の先端部２４ａ・５４ａまでの移動量ｙ１は、各摩耗部２３・５３の測定が終わったとき（つまり、各測定機構７０の測定値が最終的に一定となったとき）の、上下刃２０・５０の移動量である。   The amount of movement y1 of each non-wear part 24/54 to the tip part 24a / 54a is determined when the measurement of each wear part 23/53 is finished (that is, the measurement value of each measurement mechanism 70 is finally constant). ) Of the upper and lower blades 20 and 50.

例えば、上下刃２０・５０の摩耗幅ｗが変動した場合、その変動量に応じて各非摩耗部２４・５４の先端部２４ａ・５４ａまでの移動量ｙ１も変動する。
つまり、各先端部２１・５１・２４ａ・５４ａまでの移動量ｙ０・ｙ１の差は、上下刃２０・５０の摩耗幅ｗに対応する。 For example, when the wear width w of the upper and lower blades 20 and 50 varies, the movement amount y1 of the non-wear portions 24 and 54 to the tip portions 24a and 54a also varies according to the variation amount.
That is, the difference between the movement amounts y0 · y1 to the tip portions 21, 51, 24a, and 54a corresponds to the wear width w of the upper and lower blades 20 and 50.

ここで、各距離ｘ０・ｘ１および各移動量ｙ０・ｙ１は、それぞれ実際の距離および移動量とは異なる場合がある。   Here, each distance x0 · x1 and each movement amount y0 · y1 may be different from the actual distance and movement amount, respectively.

具体的には、各先端部２１・５１・２４ａ・５４ａまでの移動量ｙ０・ｙ１は、それぞれ各測定機構７０の測定スポット径ｓや旋回速度等に応じて、実際の移動量よりも短くなる場合がある。
また、各非摩耗部２４・５４および各摩耗部２３・５３までの距離ｘ０・ｘ１は、それぞれ各測定機構７０の測定精度等に応じて、実際の距離よりも大きくなる（あるいは小さくなる）場合がある。 Specifically, the movement amounts y0 and y1 to the respective tip portions 21, 51, 24a, and 54a are shorter than the actual movement amounts according to the measurement spot diameter s, the turning speed, and the like of each measurement mechanism 70, respectively. There is a case.
Further, when the distances x0 and x1 to the non-wear parts 24 and 54 and the wear parts 23 and 53 are larger (or smaller) than the actual distances depending on the measurement accuracy of each measurement mechanism 70, respectively. There is.

従って、各距離ｘ０・ｘ１および各移動量ｙ０・ｙ１だけで、上下刃２０・５０の摩耗深さｄ等を算出した場合、精度よく上下刃２０・５０の摩耗深さｄ等を測定できない。   Therefore, when the wear depth d and the like of the upper and lower blades 20 and 50 is calculated only by the distances x0 and x1 and the movement amounts y0 and y1, the wear depth d and the like of the upper and lower blades 20 and 50 cannot be measured with high accuracy.

切断装置１は、図１２に示すように、予め（測定工程Ｓ２を行う前に）基準値を取得している。   As shown in FIG. 12, the cutting device 1 acquires a reference value in advance (before performing the measurement step S <b> 2).

基準値は、各距離ｘ０・ｘ１および各移動量ｙ０・ｙ１から、上下刃２０・５０の摩耗深さｄと外径寸法ｒと摩耗幅ｗとを算出可能な情報である。
本実施形態の切断装置１は、基準刃１００から基準値を取得している。 The reference value is information capable of calculating the wear depth d, the outer diameter r, and the wear width w of the upper and lower blades 20 and 50 from the distances x0 and x1 and the movement amounts y0 and y1.
The cutting device 1 of this embodiment acquires a reference value from the reference blade 100.

基準刃１００は、その一端面１０２に切欠部１０３が形成される略円板状の刃具である。すなわち、本実施形態では、基準刃１００の径方向外側の端部が先端部１０１となる。   The reference blade 100 is a substantially disc-shaped cutting tool in which a notch 103 is formed on one end surface 102 thereof. That is, in the present embodiment, the end portion on the radially outer side of the reference blade 100 is the tip portion 101.

切欠部１０３は、基準刃１００の先端部１０１から上下方向（径方向）に沿って平らな面として形成され、基準刃１００の一端面１０２に対して所定の深さだけ窪んでいる部分である。切欠部１０３は、例えば、研磨機等で基準刃１００の先端部１０１を所定の寸法だけ全周にわたって削ることで形成される。
つまり、切欠部１０３は、所定の深さ寸法Ａで基準刃１００の一端面１０２に意図的に形成された摩耗部分である。 The notch 103 is a portion that is formed as a flat surface along the vertical direction (radial direction) from the tip 101 of the reference blade 100 and is recessed by a predetermined depth with respect to the one end surface 102 of the reference blade 100. . The notch 103 is formed by, for example, grinding the tip 101 of the reference blade 100 over a whole circumference with a predetermined dimension by a polishing machine or the like.
That is, the notch 103 is a wear part intentionally formed on the one end face 102 of the reference blade 100 with a predetermined depth dimension A.

また、基準刃１００の一端面１０２は、窪んでいない部分（切欠部１０３が形成されていない部分）が、非切欠部１０４として形成される。   In addition, the one end surface 102 of the reference blade 100 is formed as a non-notched portion 104 in a portion that is not recessed (a portion in which the notched portion 103 is not formed).

切断装置１は、高精度測定器（例えば、真円度測定器や三次元測定器等）によって基準刃１００を測定する。そして、基準刃１００に設定される、切欠部１０３の深さ寸法Ａと、基準刃１００の外径寸法Ｒ０と、非切欠部１０４の先端部１０４ａまでの外径寸法Ｒ１とを取得する。   The cutting device 1 measures the reference blade 100 with a high-precision measuring instrument (for example, a roundness measuring instrument or a three-dimensional measuring instrument). And the depth dimension A of the notch part 103, the outer diameter dimension R0 of the reference blade 100, and the outer diameter dimension R1 to the front-end | tip part 104a of the non-notch part 104 which are set to the reference blade 100 are acquired.

本実施形態のように基準刃１００が円板状である場合、基準刃１００の外径寸法Ｒ０は、基準刃１００の高さ寸法となる。また、非切欠部１０４の先端部１０４ａまでの外径寸法Ｒ１は、非切欠部１０４の先端部１０４ａまでの高さ寸法となる。   When the reference blade 100 is disc-shaped as in the present embodiment, the outer diameter R0 of the reference blade 100 is the height of the reference blade 100. Further, the outer diameter dimension R1 of the non-notched part 104 to the tip part 104a is the height dimension of the non-notched part 104 to the tip part 104a.

切断装置１は、上ユニット１０（または下ユニット４０）に基準刃１００をセットして、測定機構７０によって、上下方向に沿って一端面１０２の深さの変位量を測定する。   The cutting device 1 sets the reference blade 100 on the upper unit 10 (or the lower unit 40), and measures the amount of displacement of the depth of the one end face 102 along the vertical direction by the measuring mechanism 70.

このような測定結果は、上下刃２０・５０の場合と同様にして、切欠部１０３を測定しているときに測定機構７０の測定値が変動し、非切欠部１０４を測定しているときに測定機構７０の測定値が一定となる。   Similar to the case of the upper and lower blades 20 and 50, such a measurement result is obtained when the measurement value of the measurement mechanism 70 fluctuates when the notch 103 is measured and the non-notch 104 is measured. The measurement value of the measurement mechanism 70 is constant.

切断装置１は、この測定結果より、上下刃２０・５０の場合と同様に、非切欠部１０４までの距離Ｘ０と、切欠部１０３までの距離Ｘ１と、基準刃１００の先端部１０１までの移動量Ｙ０と、非切欠部１０４の先端部１０４ａまでの移動量Ｙ１とを取得する。   From this measurement result, the cutting device 1 moves to the tip portion 101 of the reference blade 100 and the distance X0 to the non-notched portion 104, the distance X1 to the notched portion 103, as in the case of the upper and lower blades 20 and 50. The amount Y0 and the amount of movement Y1 of the non-notched portion 104 to the tip portion 104a are acquired.

つまり、本実施形態の基準値は、各寸法Ａ・Ｒ０・Ｒ１と各距離Ｘ０・Ｘ１と各移動量Ｙ０・Ｙ１である。   That is, the reference values of the present embodiment are the dimensions A, R0, R1, the distances X0, X1, and the movement amounts Y0, Y1.

なお、基準刃１００の形状は、本実施形態に限定されるものでなく、例えば、クレーター形状に切欠部１０３を形成しても構わない（図８参照）。   The shape of the reference blade 100 is not limited to the present embodiment, and for example, the notch 103 may be formed in a crater shape (see FIG. 8).

非切欠部１０４および切欠部１０３までの距離Ｘ０・Ｘ１の差は、一端面１０２の深さの変位量の測定結果から算出可能な（測定誤差の影響を受けた）切欠部１０３の深さ寸法Ａである。また、切断装置１は、実際の切欠部１０３の深さ寸法Ａを基準値として取得している。   The difference between the distances X0 and X1 between the non-notch portion 104 and the notch portion 103 can be calculated from the measurement result of the displacement amount of the depth of the one end face 102 (the influence of the measurement error). A. Moreover, the cutting device 1 acquires the actual depth dimension A of the notch 103 as a reference value.

そこで、図１１および図１２に示すように、切断装置１は、非切欠部１０４および切欠部１０３までの距離Ｘ０・Ｘ１の差と、各非摩耗部２４・５４および各摩耗部２３・５３までの距離ｘ０・ｘ１の差とを比較して、その比較結果を切欠部１０３の深さ寸法Ａに反映する。
これにより、切断装置１は、上下刃２０・５０の摩耗深さｄを算出する。 Therefore, as shown in FIGS. 11 and 12, the cutting device 1 includes the difference between the distances X <b> 0 and X <b> 1 to the non-notch 104 and the notch 103, the non-wear parts 24 and 54, and the wear parts 23 and 53. And the comparison result is reflected in the depth dimension A of the notch 103.
Thereby, the cutting device 1 calculates the wear depth d of the upper and lower blades 20 and 50.

具体的には、切断装置１は、以下の式１を用いて、上下刃２０・５０の摩耗深さｄを算出する。
ｄ＝Ａ−｛（Ｘ１−Ｘ０）−（ｘ１−ｘ０）｝・・・式１ Specifically, the cutting device 1 calculates the wear depth d of the upper and lower blades 20 and 50 using the following formula 1.
d = A-{(X1-X0)-(x1-x0)} Equation 1

なお、切断装置１は、以下の式１´を用いて、上下刃２０・５０の摩耗深さｄを算出しても構わない。
ｄ＝Ａ＊（ｘ１−ｘ０）／（Ｘ１−Ｘ０）・・・式１´ In addition, the cutting device 1 may calculate the wear depth d of the upper and lower blades 20 and 50 using the following formula 1 ′.
d = A * (x1-x0) / (X1-X0) Formula 1 ′

また、前記式１および前記式１´の両方を用いて、上下刃２０・５０の摩耗深さｄを算出しても構わない。この場合、例えば、前記式１および前記式１´の平均値を、上下刃２０・５０の摩耗深さｄとすればよい。
つまり、上下刃２０・５０の摩耗深さｄは、前記式１および前記式１´の少なくともいずれか一方が用いられて算出されればよい。 Further, the wear depth d of the upper and lower blades 20 and 50 may be calculated by using both of the formula 1 and the formula 1 ′. In this case, for example, the average value of Equation 1 and Equation 1 ′ may be the wear depth d of the upper and lower blades 20, 50.
That is, the wear depth d of the upper and lower blades 20 and 50 may be calculated using at least one of the formula 1 and the formula 1 ′.

このように、切断装置１は、各一端面２２・５２の深さの変位量の測定結果（各距離ｘ０・ｘ１）と基準値（切欠部１０３の深さ寸法Ａおよび各距離Ｘ０・Ｘ１）とに基づいて、上下刃２０・５０の摩耗深さｄを算出する。
また、切断方法の測定工程Ｓ２では、各一端面２２・５２の深さの変位量の測定結果（各距離ｘ０・ｘ１）と基準値（切欠部１０３の深さ寸法Ａおよび各距離Ｘ０・Ｘ１）とに基づいて、上下刃２０・５０の摩耗深さｄを算出する。 As described above, the cutting device 1 has the measurement results (the distances x0 and x1) of the displacement amounts of the depths of the one end faces 22 and 52 and the reference values (the depth dimension A of the notch 103 and the distances X0 and X1). Based on the above, the wear depth d of the upper and lower blades 20, 50 is calculated.
Further, in the measuring step S2 of the cutting method, the measurement results (the distances x0 and x1) of the displacement amounts of the depths of the one end faces 22 and 52 and the reference values (the depth dimension A of the notch 103 and the distances X0 and X1). ) To calculate the wear depth d of the upper and lower blades 20, 50.

これによれば、基準値を基準として上下刃２０・５０の摩耗深さｄを算出できるため、各一端面２２・５２の深さの変位量の測定結果に誤差がある場合でも、上下刃２０・５０の摩耗深さｄを精度よく算出できる。   According to this, since the wear depth d of the upper and lower blades 20 and 50 can be calculated on the basis of the reference value, the upper and lower blades 20 even if there is an error in the measurement results of the displacement amounts of the depths of the one end faces 22 and 52. -The wear depth d of 50 can be calculated with high accuracy.

以上のように、切断装置１および切断方法は、測定工程Ｓ２において、各一端面２２・５２を左右方向から測定した結果と基準値とに基づいて、上下刃２０・５０の摩耗深さｄを算出するため、各摩耗部２３・５３の形状に関わらず、上下刃２０・５０の摩耗深さｄを精度よく測定できる。   As described above, in the cutting device 1 and the cutting method, the wear depth d of the upper and lower blades 20 and 50 is determined based on the result of measuring each end surface 22 and 52 from the left and right direction and the reference value in the measurement step S2. Therefore, the wear depth d of the upper and lower blades 20 and 50 can be accurately measured regardless of the shape of each wear part 23 and 53.

なお、切断装置１は、測定工程Ｓ２において、上下刃２０・５０の摩耗深さｄだけを測定する場合、各非摩耗部２４・５４および各摩耗部２３・５３までの距離ｘ０・ｘ１を測定できる程度に、各一端面２２・５２の深さの変位量を測定すればよい。
つまり、各非摩耗部２４・５４の先端部２４ａ・５４ａの近傍と各摩耗部２３・５３の平坦面２３ａ・５３ａとを測定すればよく、必ずしも上下刃２０・５０の中心Ｐ１１・Ｐ２１から先端部２１・５１までを測定する必要はない。 The cutting device 1 measures the distances x0 · x1 to the non-wear parts 24 and 54 and the wear parts 23 and 53 when measuring only the wear depth d of the upper and lower blades 20 and 50 in the measurement step S2. What is necessary is just to measure the displacement amount of the depth of each end surface 22 * 52 to the extent possible.
That is, it is only necessary to measure the vicinity of the tip portions 24a and 54a of the non-wear portions 24 and 54 and the flat surfaces 23a and 53a of the wear portions 23 and 53, and the tips are not necessarily from the centers P11 and P21 of the upper and lower blades 20 and 50. It is not necessary to measure the parts 21 and 51.

基準刃１００の先端部１０１までの移動量Ｙ０は、一端面１０２の深さの変位量の測定結果から算出可能な（測定誤差の影響を受けた）基準刃１００の外径寸法Ｒ０である。また、切断装置１は、実際の基準刃１００の外径寸法Ｒ０を基準値として取得している。   The amount of movement Y0 of the reference blade 100 to the tip 101 is the outer diameter R0 of the reference blade 100 that can be calculated from the measurement result of the displacement amount of the depth of the one end face 102 (affected by the measurement error). Further, the cutting device 1 acquires the actual outer diameter R0 of the reference blade 100 as a reference value.

そこで、切断装置１は、基準刃１００の先端部１０１までの移動量Ｙ０と、上下刃２０・５０の先端部２１・５１までの移動量ｙ０とを比較して、その比較結果を基準刃１００の外径寸法Ｒ０に反映する。
これにより、切断装置１は、上下刃２０・５０の外径寸法ｒを算出する。 Accordingly, the cutting device 1 compares the movement amount Y0 of the reference blade 100 to the tip portion 101 with the movement amount y0 of the upper and lower blades 20 and 50 to the tip portions 21 and 51, and compares the comparison result with the reference blade 100. This is reflected in the outer diameter R0.
Thereby, the cutting device 1 calculates the outer diameter dimension r of the upper and lower blades 20 and 50.

具体的には、切断装置１は、以下の式２を用いて、上下刃２０・５０の外径寸法ｒを算出する。
ｒ＝Ｒ０−（Ｙ０−ｙ０）・・・式２ Specifically, the cutting device 1 calculates the outer diameter r of the upper and lower blades 20 and 50 using the following formula 2.
r = R0− (Y0−y0) Equation 2

なお、切断装置１は、以下の式２´を用いて、上下刃２０・５０の外径寸法ｒを算出しても構わない。
ｒ＝Ｒ０＊（ｙ０／Ｙ０）・・・式２´ Note that the cutting device 1 may calculate the outer diameter r of the upper and lower blades 20 and 50 using the following expression 2 ′.
r = R0 * (y0 / Y0) Formula 2 ′

また、前記式２および前記式２´の両方を用いて、上下刃２０・５０の外径寸法ｒを算出しても構わない。この場合、例えば、前記式２および前記式２´の平均値を、上下刃２０・５０の外径寸法ｒとすればよい。
つまり、上下刃２０・５０の外径寸法ｒは、前記式２および前記式２´の少なくともいずれか一方を用いられて算出されればよい。 In addition, the outer diameter r of the upper and lower blades 20 and 50 may be calculated by using both the expression 2 and the expression 2 ′. In this case, for example, the average value of the formula 2 and the formula 2 ′ may be the outer diameter r of the upper and lower blades 20, 50.
That is, the outer diameter r of the upper and lower blades 20 and 50 may be calculated using at least one of the formula 2 and the formula 2 ′.

このように、切断装置１は、各一端面２２・５２の深さの変位量の測定結果（上下刃２０・５０の先端部２１・５１までの移動量ｙ０）と基準値（基準刃１００の外径寸法Ｒ０および基準刃１００の先端部１０１までの移動量Ｙ０）とに基づいて、上下刃２０・５０の外径寸法ｒを算出する。
また、切断方法の測定工程Ｓ２では、各一端面２２・５２の深さの変位量の測定結果（上下刃２０・５０の先端部２１・５１までの移動量ｙ０）と基準値（基準刃１００の外径寸法Ｒ０および基準刃１００の先端部１０１までの移動量Ｙ０）とに基づいて、上下刃２０・５０の外径寸法ｒを算出する。 As described above, the cutting device 1 is configured to measure the displacement amount of the depths of the one end faces 22 and 52 (the amount of movement y0 of the upper and lower blades 20 and 50 to the tip portions 21 and 51) and the reference value (of the reference blade 100). Based on the outer diameter R0 and the amount of movement Y0) of the reference blade 100 to the tip 101, the outer diameter r of the upper and lower blades 20 and 50 is calculated.
Further, in the measurement step S2 of the cutting method, the measurement result of the displacement amount of the depth of each one end face 22, 52 (movement amount y0 to the tip portions 21, 51 of the upper and lower blades 20, 50) and the reference value (reference blade 100). The outer diameter dimension r of the upper and lower blades 20 and 50 is calculated based on the outer diameter dimension R0 and the amount of movement Y0) of the reference blade 100 to the tip 101.

これによれば、基準値を基準として上下刃２０・５０の外径寸法ｒを算出できるため、各一端面２２・５２の深さの変位量の測定結果に誤差がある場合でも、上下刃２０・５０の外径寸法ｒを精度よく算出できる。   According to this, since the outer diameter dimension r of the upper and lower blades 20 and 50 can be calculated based on the reference value, even if there is an error in the measurement results of the displacement amounts of the depths of the one end faces 22 and 52, the upper and lower blades 20 and 50 can be calculated.・ The outer diameter r of 50 can be calculated with high accuracy.

また、切断装置１および切断方法は、上下刃２０・５０を左右方向から測定する各測定機構７０だけで、上下刃２０・５０の摩耗深さｄに加えて、外径寸法ｒも測定できる。
つまり、一つの測定器で上下刃２０・５０の摩耗深さｄおよび外径寸法ｒを測定できる。このため、上下刃２０・５０を再研磨したときや交換したときに、三次元測定器等で別途上下刃２０・５０の外径寸法ｒを測定する必要がなくなる。 In addition, the cutting device 1 and the cutting method can measure the outer diameter r in addition to the wear depth d of the upper and lower blades 20 and 50 only by the measurement mechanisms 70 that measure the upper and lower blades 20 and 50 from the left and right directions.
That is, the wear depth d and the outer diameter r of the upper and lower blades 20 and 50 can be measured with a single measuring instrument. For this reason, when the upper and lower blades 20 and 50 are re-polished or replaced, it is not necessary to separately measure the outer diameter r of the upper and lower blades 20 and 50 with a three-dimensional measuring instrument or the like.

さらに、切断装置１および切断方法は、一回の測定動作で上下刃２０・５０の摩耗深さｄおよび外径寸法ｒを測定できるため、上下刃２０・５０の摩耗深さｄおよび外径寸法ｒの測定に要する時間を短縮できる。   Furthermore, since the cutting device 1 and the cutting method can measure the wear depth d and the outer diameter r of the upper and lower blades 20 and 50 in one measurement operation, the wear depth d and the outer diameter of the upper and lower blades 20 and 50 are measured. The time required for measuring r can be shortened.

なお、切断装置１は、測定工程Ｓ２において、上下刃２０・５０の外径寸法ｒだけを測定する場合、上下刃２０・５０の先端部２１・５１までの移動量ｙ０を測定できる程度に、各一端面２２・５２の深さの変位量を測定すればよい。
つまり、上下刃２０・５０の先端部２１・５１だけを測定すればよい。 In the measuring step S2, when the cutting device 1 measures only the outer diameter r of the upper and lower blades 20 and 50, the cutting device 1 can measure the amount of movement y0 to the tip portions 21 and 51 of the upper and lower blades 20 and 50. What is necessary is just to measure the displacement amount of the depth of each end surface 22 * 52.
That is, only the tip portions 21 and 51 of the upper and lower blades 20 and 50 need be measured.

各先端部１０１・１０４ａまでの移動量Ｙ０・Ｙ１の差は、一端面１０２の深さの変位量の測定結果から算出可能な（測定誤差の影響を受けた）切欠部１０３の高さ寸法である。また、切欠部１０３の高さ寸法は、実際の切欠部１０３の外径寸法Ｒ０と非切欠部１０４の先端部１０４ａまでの外径寸法Ｒ１との差である。切断装置１は、各外径寸法Ｒ０・Ｒ１を基準値として取得している。   The difference between the movement amounts Y0 and Y1 to the tip portions 101 and 104a is the height dimension of the notch 103 that can be calculated from the measurement result of the displacement of the depth of the one end face 102 (affected by the measurement error). is there. The height dimension of the notch 103 is a difference between the actual outer diameter R0 of the notch 103 and the outer diameter R1 of the non-notch 104 to the tip 104a. The cutting device 1 acquires the outer diameters R0 and R1 as reference values.

そこで、切断装置１は、各先端部１０１・１０４ａまでの移動量Ｙ０・Ｙ１の差と、各先端部２１・５１・２４ａ・５４ａまでの移動量ｙ０・ｙ１の差とを比較して、その比較結果を切欠部１０３の高さ寸法（各外径寸法Ｒ０・Ｒ１の差）に反映する。
これにより、切断装置１は、上下刃２０・５０の摩耗幅ｗを算出する。 Therefore, the cutting device 1 compares the difference between the movement amounts Y0 and Y1 up to the tip portions 101 and 104a with the difference between the movement amounts y0 and y1 up to the tip portions 21, 51, 24a, and 54a. The comparison result is reflected in the height dimension of the notch 103 (difference between the outer diameter dimensions R0 and R1).
Thereby, the cutting device 1 calculates the wear width w of the upper and lower blades 20 and 50.

具体的には、切断装置１は、以下の式３を用いて、上下刃２０・５０の摩耗幅ｗを算出する。
ｗ＝（Ｒ１−Ｒ０）−｛（Ｙ１−Ｙ０）−（ｙ１−ｙ０）｝・・・式３ Specifically, the cutting device 1 calculates the wear width w of the upper and lower blades 20 and 50 using the following formula 3.
w = (R1-R0)-{(Y1-Y0)-(y1-y0)} Equation 3

なお、切断装置１は、以下の式３´を用いて、上下刃２０・５０の摩耗幅ｗを算出しても構わない。
ｗ＝（Ｒ１−Ｒ０）＊（ｙ１−ｙ０）／（Ｙ１−Ｙ０）・・・式３´ In addition, the cutting device 1 may calculate the wear width w of the upper and lower blades 20 and 50 using the following expression 3 ′.
w = (R1-R0) * (y1-y0) / (Y1-Y0) Formula 3 '

また、前記式３および前記式３´の両方を用いて、上下刃２０・５０の摩耗幅ｗを算出しても構わない。この場合、例えば、前記式３および前記式３´の平均値を、上下刃２０・５０の摩耗幅ｗとすればよい。
つまり、上下刃２０・５０の摩耗幅ｗは、前記式３および前記式３´の少なくともいずれか一方を用いられて算出されればよい。 Further, the wear width w of the upper and lower blades 20 and 50 may be calculated by using both the expression 3 and the expression 3 ′. In this case, for example, the average value of Equation 3 and Equation 3 ′ may be the wear width w of the upper and lower blades 20 and 50.
That is, the wear width w of the upper and lower blades 20 and 50 may be calculated using at least one of the formula 3 and the formula 3 ′.

このように、切断装置１は、各一端面２２・５２の深さの変位量の測定結果（各移動量ｙ０・ｙ１）と基準値（各外径寸法Ｒ０・Ｒ１および各移動量Ｙ０・Ｙ１）とに基づいて、上下刃２０・５０の摩耗幅ｗを算出する。
また、切断方法の測定工程Ｓ２では、各一端面２２・５２の深さの変位量の測定結果（各移動量ｙ０・ｙ１）と基準値（各外径寸法Ｒ０・Ｒ１および各移動量Ｙ０・Ｙ１）とに基づいて、上下刃２０・５０の摩耗幅ｗを算出する。 As described above, the cutting device 1 has the measurement results of the displacement amounts of the depths of the one end faces 22 and 52 (respective movement amounts y0 and y1) and the reference values (respective outer diameter dimensions R0 and R1 and movement amounts Y0 and Y1). ) To calculate the wear width w of the upper and lower blades 20, 50.
Further, in the measuring step S2 of the cutting method, the measurement results of the displacement amounts of the depths of the one end faces 22 and 52 (respective movement amounts y0 and y1) and reference values (respective outer diameter dimensions R0 and R1 and movement amounts Y0 and Y0). The wear width w of the upper and lower blades 20 and 50 is calculated based on Y1).

これによれば、基準値を基準として上下刃２０・５０の摩耗幅ｗを算出できるため、各一端面２２・５２の深さの変位量の測定結果に誤差がある場合でも、上下刃２０・５０の摩耗幅ｗを精度よく算出できる。   According to this, since the wear width w of the upper and lower blades 20 and 50 can be calculated on the basis of the reference value, even if there is an error in the measurement result of the displacement amount of the depths of the one end surfaces 22 and 52, the upper and lower blades 20 The wear width w of 50 can be calculated with high accuracy.

また、前記式１から前記式３（および前記式１´から前記式３´）を用いることで、上下刃２０・５０の摩耗深さｄと外径寸法ｒと摩耗幅ｗとを、簡単に算出できるとともに精度よく算出できる。   Further, by using the above formula 1 to the above formula 3 (and the above formula 1 'to the above formula 3'), the wear depth d, the outer diameter r and the wear width w of the upper and lower blades 20 and 50 can be easily obtained. It can be calculated with high accuracy.

上下刃２０・５０の摩耗幅ｗは、オーバーラップ量Ｄに応じて変動する。具体的には、図１３（ａ）に示すように、オーバーラップ量Ｄが多い場合、上下刃２０・５０の摩耗幅ｗは大きくなる。一方、図１３（ｂ）に示すように、オーバーラップ量Ｄが小さい場合、上下刃２０・５０の摩耗幅ｗは小さくなる。   The wear width w of the upper and lower blades 20, 50 varies according to the overlap amount D. Specifically, as shown in FIG. 13A, when the overlap amount D is large, the wear width w of the upper and lower blades 20 and 50 is increased. On the other hand, as shown in FIG. 13B, when the overlap amount D is small, the wear width w of the upper and lower blades 20 and 50 is reduced.

すなわち、切断装置１は、測定工程Ｓ２にて上下刃２０・５０の摩耗幅ｗを算出することで、オーバーラップ量Ｄが、所定の範囲内に設定された状態で、シート状物１１０を切断していたかどうかを判断できる。
つまり、切断装置１および切断方法は、最適なオーバーラップ量Ｄを設定した状態で、シート状物１１０を切断していたかどうかを判断できる。 That is, the cutting device 1 calculates the wear width w of the upper and lower blades 20 and 50 in the measurement step S2, and cuts the sheet-like object 110 in a state where the overlap amount D is set within a predetermined range. You can determine whether you were doing.
That is, the cutting apparatus 1 and the cutting method can determine whether or not the sheet-like object 110 has been cut in a state where the optimum overlap amount D is set.

なお、切断装置１は、測定工程Ｓ２において、上下刃２０・５０の摩耗幅ｗだけを測定する場合、各先端部２１・５１・２４ａ・５４ａまでの移動量ｙ０・ｙ１を測定できる程度に、各一端面２２・５２の深さの変位量を測定すればよい。
つまり、上下刃２０・５０の先端部２１・５１から各非摩耗部２４・５４の先端部２４ａ・５４ａの近傍までを測定すればよい。 In addition, when measuring only the wear width w of the upper and lower blades 20 and 50 in the measurement step S2, the cutting device 1 is capable of measuring the movement amounts y0 and y1 to the tip portions 21, 51, 24a, and 54a. What is necessary is just to measure the displacement amount of the depth of each end surface 22 * 52.
That is, what is necessary is just to measure from the front-end | tip part 21 * 51 of the upper-and-lower blades 20 * 50 to the front-end | tip part 24a * 54a vicinity of each non-wear part 24 * 54.

切断装置１は、調整工程Ｓ３において、上下刃２０・５０の摩耗深さｄに基づいてクリアランス量Ｃを調整するとともに、上下刃２０・５０の外径寸法ｒに基づいてオーバーラップ量Ｄを調整する。
すなわち、切断方法では、上下刃２０・５０の摩耗深さｄに基づいてクリアランス量Ｃを調整するとともに、上下刃２０・５０の外径寸法ｒに基づいてオーバーラップ量Ｄを調整する調整工程Ｓ３を行う。 In the adjusting step S3, the cutting device 1 adjusts the clearance amount C based on the wear depth d of the upper and lower blades 20 and 50, and adjusts the overlap amount D based on the outer diameter r of the upper and lower blades 20 and 50. To do.
That is, in the cutting method, an adjustment step S3 in which the clearance amount C is adjusted based on the wear depth d of the upper and lower blades 20 and 50 and the overlap amount D is adjusted based on the outer diameter r of the upper and lower blades 20 and 50. I do.

図１４に示すように、上下刃２０・５０の摩耗深さｄだけ下刃５０を右方向に移動させ、クリアランス量Ｃを調整する。
また、図１５、図１６（ａ）、および図１６（ｂ）に示すように、上下刃２０・５０の外径寸法ｒに基づいて、上下刃２０・５０を旋回させ、オーバーラップ量Ｄを調整する。 As shown in FIG. 14, the lower blade 50 is moved rightward by the wear depth d of the upper and lower blades 20, 50, and the clearance amount C is adjusted.
Further, as shown in FIG. 15, FIG. 16 (a), and FIG. 16 (b), the upper and lower blades 20 and 50 are turned based on the outer diameter r of the upper and lower blades 20 and 50, and the overlap amount D is set. adjust.

図５に示すように、切断装置１は、以上のような、切断工程Ｓ１、測定工程Ｓ２、および調整工程Ｓ３を繰り返し行う。
すなわち、切断装置１は、シート状物１１０を切断するとともに、定期的にクリアランス量Ｃおよびオーバーラップ量Ｄを測定し、クリアランス量Ｃおよびオーバーラップ量Ｄが所定の範囲を超える前に調整する。 As shown in FIG. 5, the cutting device 1 repeatedly performs the cutting step S1, the measuring step S2, and the adjusting step S3 as described above.
That is, the cutting device 1 cuts the sheet 110 and periodically measures the clearance amount C and the overlap amount D, and adjusts the clearance amount C and the overlap amount D before they exceed a predetermined range.

これによれば、切断装置１は、上下刃２０・５０が摩耗した場合や上下刃２０・５０を再研磨した（または交換した）場合でも、クリアランス量Ｃおよびオーバーラップ量Ｄを精度よく調整できる。従って、常に所定の範囲内でクリアランス量Ｃおよびオーバーラップ量Ｄを維持できるため、上下刃２０・５０を長寿命化できる。   Accordingly, the cutting device 1 can accurately adjust the clearance amount C and the overlap amount D even when the upper and lower blades 20 and 50 are worn or when the upper and lower blades 20 and 50 are re-polished (or replaced). . Accordingly, since the clearance amount C and the overlap amount D can always be maintained within a predetermined range, the upper and lower blades 20 and 50 can have a longer life.

なお、切断装置１は、調整工程Ｓ３において、オーバーラップ量Ｄを調整するときに、必ずしも上下刃２０・５０をそれぞれ上下方向に相対的に移動させる必要はない。例えば、切断装置１は、図１７（ａ）および図１７（ｂ）に示すように、オーバーラップ量Ｄを調整するときに、上刃２０を下刃５０に対して上下方向に相対的に移動させても構わない。   Note that the cutting device 1 does not necessarily have to move the upper and lower blades 20 and 50 relatively in the vertical direction when adjusting the overlap amount D in the adjustment step S3. For example, as shown in FIGS. 17A and 17B, the cutting device 1 moves the upper blade 20 relative to the lower blade 50 in the vertical direction when adjusting the overlap amount D. It does n’t matter.

しかし、上刃２０を下刃５０に対して上下方向に相対的に移動させる場合、シート状物１１０を切断する高さ位置が変動してしまう。
また、切断装置１の前方および後方には、シート状物１１０をガイドする二つのフリーローラ８０が設けられる。 However, when the upper blade 20 is moved relative to the lower blade 50 in the vertical direction, the height position at which the sheet-like object 110 is cut fluctuates.
Further, two free rollers 80 for guiding the sheet-like object 110 are provided in front of and behind the cutting device 1.

このため、図１７（ｂ）に示すように、シート状物１１０の上下刃２０・５０への侵入角度が変わってしまう。
この場合、各フリーローラ８０の高さ位置も調整する必要があるため、オーバーラップ量Ｄの調整に時間がかかってしまう。 For this reason, as shown in FIG.17 (b), the penetration | invasion angle to the upper-and-lower blades 20 * 50 of the sheet-like object 110 will change.
In this case, since it is necessary to adjust the height position of each free roller 80, it takes time to adjust the overlap amount D.

一方、本実施形態において、上下刃２０・５０をそれぞれ上下方向に相対的に移動させる場合、図１６（ａ）および図１６（ｂ）に示すように、オーバーラップ量Ｄを調整するときに、シート状物１１０を切断する高さ位置が変動しない。
つまり、切断装置１は、オーバーラップ量Ｄを調整するときに、各フリーローラ８０の位置を調整する必要がなくなるため、オーバーラップ量Ｄの調整作業をより簡略化できる。 On the other hand, in this embodiment, when the upper and lower blades 20 and 50 are relatively moved in the vertical direction, as shown in FIGS. 16 (a) and 16 (b), when the overlap amount D is adjusted, The height position at which the sheet 110 is cut does not vary.
In other words, since the cutting device 1 does not need to adjust the position of each free roller 80 when adjusting the overlap amount D, the adjustment work of the overlap amount D can be further simplified.

このため、切断装置１は、オーバーラップ量Ｄを調整するときに、上下刃２０・５０をそれぞれ上下方向に相対的に移動させることが好ましい。   For this reason, when adjusting the overlap amount D, it is preferable that the cutting device 1 moves the upper and lower blades 20 and 50 relatively in the vertical direction.

切断装置１は、各一端面２２・５２の深さの変位量を測定するときに、必ずしも上下刃２０・５０を各測定機構７０に対して相対的に移動させる必要はない。すなわち、切断装置１は、各測定機構７０を上下刃２０・５０に対して相対的に移動させても構わない。   The cutting device 1 does not necessarily need to move the upper and lower blades 20, 50 relative to the measuring mechanisms 70 when measuring the amount of displacement of the depths of the one end faces 22, 52. That is, the cutting device 1 may move each measuring mechanism 70 relative to the upper and lower blades 20 and 50.

ただし、各測定機構７０を移動させて各一端面２２・５２までの距離を測定する場合、各測定機構７０の移動に起因して測定誤差が発生してしまう。   However, when the measurement mechanisms 70 are moved and the distances to the one end faces 22 and 52 are measured, a measurement error occurs due to the movement of the measurement mechanisms 70.

このような測定誤差の発生を防止できるという観点から、図１１に示すように、切断装置１は、各一端面２２・５２の深さの変位量を測定するときに、上下刃２０・５０を各測定機構７０に対して相対的に移動させることが好ましい。   From the viewpoint of preventing the occurrence of such a measurement error, as shown in FIG. 11, the cutting device 1 uses the upper and lower blades 20, 50 when measuring the displacement amount of the depth of each end face 22, 52. It is preferable to move relative to each measurement mechanism 70.

切断装置１は、必ずしも各ラップ調整機構３４・６４により、各測定機構７０に対して上下刃２０・５０を上下方向に沿って相対的に移動させる必要はない。   The cutting device 1 does not necessarily need to move the upper and lower blades 20 and 50 relative to the measurement mechanisms 70 along the vertical direction by the lap adjustment mechanisms 34 and 64.

ただし、各ラップ調整機構３４・６４を備えることで、切断装置１は、図２に示すように、各自転軸３１・６１（第一軸３１ａ・６１ａおよび第二軸３１ｂ・６１ｂ）を左側だけで支持する片持ち構造にできる。
つまり、切断装置１は、各自転軸受３２・６２に加えて、各公転軸３５・６５および各公転軸受３６・６６により各自転軸３１・６１を支持する構成となる。 However, by providing the lap adjustment mechanisms 34 and 64, the cutting device 1 allows the rotation shafts 31 and 61 (first shafts 31a and 61a and second shafts 31b and 61b) only on the left side, as shown in FIG. Cantilever structure supported by
That is, the cutting device 1 is configured to support the rotation shafts 31 and 61 by the respective revolution shafts 35 and 65 and the respective revolution bearings 36 and 66 in addition to the respective rotation bearings 32 and 62.

これによれば、片持ち構造でも上下刃２０・５０を確実に支持できるため、上下刃２０・５０の回転ブレの発生を防止できる。つまり、片持ち構造でもシート状物１１０を切断するために必要な剛性を確保できる。   According to this, since the upper and lower blades 20 and 50 can be reliably supported even in a cantilever structure, it is possible to prevent the rotation of the upper and lower blades 20 and 50 from occurring. That is, the rigidity necessary for cutting the sheet-like object 110 can be secured even in a cantilever structure.

また、片持ち構造にすることで、切断装置１は、両持ち構造（各自転軸３１・６１を左右両側の軸受により支持する構造）の場合と比較して、上下刃２０・５０の左方に位置する部品点数を少なくできる。   In addition, by using a cantilever structure, the cutting device 1 has a left-hand side of the upper and lower blades 20 and 50 as compared with a case of a double-supported structure (a structure in which the rotation shafts 31 and 61 are supported by left and right bearings). The number of parts located in can be reduced.

これによれば、切断装置１は、上下刃２０・５０の取付けや取外しを容易に行うことができる。このため、上下刃２０・５０の交換作業や再研磨作業を単純化できるとともに、より短時間で行うことができる。   According to this, the cutting device 1 can perform attachment and removal of the upper and lower blades 20 and 50 easily. For this reason, the replacement work and re-polishing work of the upper and lower blades 20 and 50 can be simplified and can be performed in a shorter time.

以上より、切断装置１は、各ラップ調整機構３４・６４により各測定機構７０に対して上下刃２０・５０を上下方向に沿って相対的に移動させる構成とすることが好ましい。   From the above, it is preferable that the cutting device 1 has a configuration in which the upper and lower blades 20 and 50 are relatively moved along the vertical direction with respect to the measurement mechanisms 70 by the lap adjustment mechanisms 34 and 64.

各測定機構７０は、それぞれ各一端面２２・５２を測定するときの測定スポット径ｓが、以下の式４を満たす条件にて設定されることが好ましい。
ｓ≦Ｗ／２・・・式４
ここで、前記式４において、Ｗは、上下刃２０・５０の摩耗幅ｗの最小値である。このような上下刃２０・５０の摩耗幅ｗの最小値は、実験等によって予め算出される。 In each measurement mechanism 70, it is preferable that the measurement spot diameter s when measuring the one end faces 22 and 52 is set under a condition satisfying the following Expression 4.
s ≦ W / 2 Formula 4
Here, in Formula 4, W is the minimum value of the wear width w of the upper and lower blades 20 and 50. Such a minimum value of the wear width w of the upper and lower blades 20 and 50 is calculated in advance by an experiment or the like.

このように構成することで、各測定機構７０は、各一端面２２・５２の深さの変位量を測定するときに、確実に各摩耗部２３・５３の平坦面２３ａ・５３ａを測定できる。つまり、切断装置１は、各摩耗部２３・５３までの距離ｘ１を確実に測定できる。   With this configuration, each measuring mechanism 70 can reliably measure the flat surfaces 23a and 53a of the wear parts 23 and 53 when measuring the displacement of the depths of the one end faces 22 and 52, respectively. That is, the cutting device 1 can reliably measure the distance x1 to each of the wear parts 23 and 53.

本実施形態の上下刃２０・５０および基準刃１００は、略円板状としたが、これに限定されるものでなく、例えば、略板状であっても構わない。
この場合、上下刃２０・５０および基準刃１００の長手方向の寸法が、一対の刃具および基準刃の高さ寸法に対応する。 The upper and lower blades 20 and 50 and the reference blade 100 of the present embodiment are substantially disk-shaped, but are not limited to this, and may be, for example, substantially plate-shaped.
In this case, the longitudinal dimensions of the upper and lower blades 20 and 50 and the reference blade 100 correspond to the height of the pair of cutting tools and the reference blade.
