At this time, the first driving rollers 13 and the second driving rollers 15 are rotated by driving of the motors 16 and 18, respectively, while the non-driving rollers 14a and 14b are passively following the flow of the glass ribbon G. It is rotated. The rotational speed (circumferential speed) of the second drive roller 15 that pulls the glass ribbon G is set to be faster than the rotational speed (circumferential speed) of the first drive roller 13, and the first and second drive rollers 13, The non-driving rollers 14 a and 14 b located between 15 are preferably rotated at a rotational speed (circumferential speed) equal to or higher than the rotational speed of the first drive roller 13 and lower than the rotational speed of the second drive roller 15. As described above, when the first driving roller 13 and the non-driving rollers 14a and 14b are configured as cooling rollers for cooling the end portion in the width direction of the glass ribbon G, the first driving roller 13 and the non-driving rollers 14a and 14b On the other hand, the viscosity of the end portion is increased, and the shrinkage of the glass ribbon G to the inner side in the width direction is more suitably suppressed.

ここで、非駆動ローラ１４ａやそれ以外の製造設備（成形部１２及び第１及び第２駆動ローラ１３，１５を含む設備）の異常が原因で、非駆動ローラ１４ａの回転速度に異常が生じる、つまり、非駆動ローラ１４ａの回転速度が正常範囲よりも速く又は遅くなることがある。例えば、成形部１２や第１駆動ローラ１３等の非駆動ローラ１４ａよりも上段の製造設備の何らかの異常によって、非駆動ローラ１４ａに到達するガラスリボンＧの形状に異常が生じた場合、非駆動ローラ１４ａの回転速度に異常が生じる。また、例えば、非駆動ローラ１４ａを軸支するベアリングの不具合によって非駆動ローラ１４ａのスムーズな回転が阻害されている場合や、非駆動ローラ１４ａに軸ぶれ（軸直交方向への振動）が発生している場合、非駆動ローラ１４ａの回転速度に異常が生じる。   Here, due to an abnormality in the non-driving roller 14a and other manufacturing equipment (equipment including the molding unit 12 and the first and second driving rollers 13 and 15), an abnormality occurs in the rotational speed of the non-driving roller 14a. That is, the rotational speed of the non-driving roller 14a may be faster or slower than the normal range. For example, when an abnormality occurs in the shape of the glass ribbon G reaching the non-driving roller 14a due to some abnormality in the manufacturing equipment above the non-driving roller 14a such as the molding unit 12 or the first driving roller 13, the non-driving roller An abnormality occurs in the rotational speed of 14a. Further, for example, when the smooth rotation of the non-driving roller 14a is hindered by a failure of the bearing that pivotally supports the non-driving roller 14a, or the non-driving roller 14a is shaken (vibration in the direction perpendicular to the axis). If so, an abnormality occurs in the rotational speed of the non-driving roller 14a.

非駆動ローラ１４ａに回転異常が生じると、回転検出部２１からの出力信号に基づいて制御部２０にて算出される非駆動ローラ１４ａの回転速度が異常値を示し、制御部２０から報知部２２に異常検出信号が出力される。そして、その異常検出信号に基づいて報知部２２のディスプレイ２３及びスピーカ２４にて非駆動ローラ１４ａの回転異常の報知が実行される。つまり、この報知によって、非駆動ローラ１４ａやその他の製造設備（成形部１２及び第１及び第２駆動ローラ１３，１５等）に異常が生じていることを作業者が把握することが可能となっている。   When a rotation abnormality occurs in the non-drive roller 14a, the rotation speed of the non-drive roller 14a calculated by the control unit 20 based on the output signal from the rotation detection unit 21 shows an abnormal value. An abnormality detection signal is output. Based on the abnormality detection signal, the display 23 and the speaker 24 of the notification unit 22 notify the rotation abnormality of the non-driving roller 14a. That is, by this notification, it becomes possible for the operator to know that an abnormality has occurred in the non-driving roller 14a and other manufacturing equipment (such as the molding unit 12 and the first and second driving rollers 13, 15). ing.

次に、本実施形態の特徴的な効果を記載する。
（１）ガラスリボン製造装置１１は、非駆動ローラ１４ａの回転を検出する回転検出部２１と、回転検出部２１にて検出された非駆動ローラ１４ａの回転情報に基づいて該非駆動ローラ１４ａの状態異常を検出する制御部２０と、制御部２０による異常検出に基づいて非駆動ローラ１４ａの状態異常を報知する報知部２２とを備える。この構成によれば、非駆動ローラ１４ａに状態異常が生じたときに、報知部２２が対処動作としてその状態異常を報知するため、非駆動ローラ１４ａやその他の製造設備に異常が生じたことを作業者が迅速に把握することができる。その結果、成形部１２及び各種ローラ１３，１４ａ，１４ｂ，１５を含む製造設備における異常箇所の確認、及びその異常への対応を速やかに実行することが可能となる。 Next, characteristic effects of the present embodiment will be described.
(1) The glass ribbon manufacturing apparatus 11 includes a rotation detecting unit 21 that detects the rotation of the non-driving roller 14a, and the state of the non-driving roller 14a based on the rotation information of the non-driving roller 14a detected by the rotation detecting unit 21. A control unit 20 that detects an abnormality, and a notification unit 22 that notifies a state abnormality of the non-driving roller 14a based on the abnormality detection by the control unit 20 are provided. According to this configuration, when a state abnormality occurs in the non-driving roller 14a, the notification unit 22 notifies the state abnormality as a coping operation, so that an abnormality has occurred in the non-driving roller 14a and other manufacturing equipment. An operator can grasp quickly. As a result, it is possible to promptly execute confirmation of an abnormal location in the manufacturing facility including the forming unit 12 and the various rollers 13, 14 a, 14 b, 15 and response to the abnormality.

（２）回転検出部２１及び制御部２０によって非駆動ローラ１４ａの回転速度の異常が検知され、その回転速度の異常が報知部２２にて報知される。この構成によれば、製造設備の種々の異常及びそれに起因するガラスリボンＧの形状異常が非駆動ローラ１４ａの回転速度に反映されやすいため、非駆動ローラ１４ａの回転速度の異常が報知部２２にて報知されることで、様々な異常の多くに対応できる。   (2) An abnormality in the rotational speed of the non-driving roller 14a is detected by the rotation detection unit 21 and the control unit 20, and the abnormality in the rotational speed is notified by the notification unit 22. According to this configuration, various abnormalities in the manufacturing equipment and the abnormal shape of the glass ribbon G resulting therefrom are easily reflected in the rotational speed of the non-driving roller 14a. Can be used to deal with many of the various abnormalities.

（３）回転検出部２１及び制御部２０による異常検知の対象を非駆動ローラ１４ａとしている。非駆動ローラ１４ａは、ガラスリボンＧの流れに追従して受動的に回転するものであることから、設備異常に起因するガラスリボンＧの形状異常が非駆動ローラ１４ａの回転速度に反映されやすい。このため、ガラスリボンＧの形状異常、ひいてはそれを引き起こす設備異常を作業者がより好適に把握することが可能となる。   (3) The abnormality detection target by the rotation detection unit 21 and the control unit 20 is the non-driving roller 14a. Since the non-driving roller 14a rotates passively following the flow of the glass ribbon G, the abnormal shape of the glass ribbon G due to equipment abnormality is easily reflected in the rotational speed of the non-driving roller 14a. For this reason, an operator can grasp | ascertain the shape abnormality of the glass ribbon G, and the equipment abnormality which causes it more suitably.

なお、上記実施形態は、以下のように変更してもよい。
・上記実施形態では、非駆動ローラ１４ａ，１４ｂのうちの非駆動ローラ１４ａの回転速度を検出し、その回転速度に基づいて異常を検出しているが、非駆動ローラ１４ｂの回転速度、又は非駆動ローラ１４ａ，１４ｂ両方の回転速度を検出し、その回転速度に基づいて異常を検出してもよい。 In addition, you may change the said embodiment as follows.
In the above embodiment, the rotational speed of the non-driving roller 14a out of the non-driving rollers 14a and 14b is detected, and abnormality is detected based on the rotational speed. However, the rotational speed of the non-driving roller 14b or The rotational speeds of both the drive rollers 14a and 14b may be detected, and an abnormality may be detected based on the rotational speed.

・上記実施形態では特に言及しなかったが、制御部２０から入力される異常検出信号に基づいて非駆動ローラ１４ａをガラスリボンＧから厚み方向Ｙ又は幅方向Ｘに離間するように退避させる例えば流体圧シリンダ等の退避駆動部２５（図１参照）を設けてもよい。この場合、制御部２０は、非駆動ローラ１４ａの回転異常を検出すると、報知部２２及び退避駆動部２５に異常検出信号を出力し、報知部２２にて回転異常の報知が実行されるとともに、退避駆動部２５の駆動によって非駆動ローラ１４ａがガラスリボンＧに対して厚み方向Ｙ又は幅方向Ｘに退避される。   Although not particularly mentioned in the above embodiment, for example, a fluid that retracts the non-driving roller 14a away from the glass ribbon G in the thickness direction Y or the width direction X based on an abnormality detection signal input from the control unit 20 A retraction drive unit 25 (see FIG. 1) such as a pressure cylinder may be provided. In this case, when detecting the rotation abnormality of the non-driving roller 14a, the control unit 20 outputs an abnormality detection signal to the notification unit 22 and the retracting drive unit 25, and the notification unit 22 executes the rotation abnormality notification. The non-driving roller 14 a is retracted in the thickness direction Y or the width direction X with respect to the glass ribbon G by driving the retracting drive unit 25.

このような構成によれば、非駆動ローラ１４ａの回転異常が検出されると、非駆動ローラ１４ａが退避駆動部２５の駆動によってガラスリボンＧから離間されるため、回転異常が生じている非駆動ローラ１４ａがガラスリボンＧに与える影響を小さく抑えることができる。例えば、ベアリング等の不具合によって非駆動ローラ１４ａの回転が極めて鈍くなった場合では、ガラスリボンＧが非駆動ローラ１４ａとの接触によって飛散し、その飛散したガラスが後段の設備（第２駆動ローラ１５やそれ以降の設備）に降りかかるおそれがある。   According to such a configuration, when a rotation abnormality of the non-driving roller 14a is detected, the non-driving roller 14a is separated from the glass ribbon G by the drive of the retracting drive unit 25. The influence which the roller 14a has on the glass ribbon G can be suppressed small. For example, when the rotation of the non-driving roller 14a becomes extremely slow due to a problem such as a bearing, the glass ribbon G scatters due to contact with the non-driving roller 14a, and the scattered glass becomes the subsequent equipment (second driving roller 15 Or equipment after that).

その点、この構成では、回転異常が検出されると非駆動ローラ１４ａが退避駆動部２５の駆動によってガラスリボンＧから退避されるため、回転異常が生じた非駆動ローラ１４ａによってガラスリボンＧが飛散するといった事態を免れることができ、非駆動ローラ１４ａに回転異常が生じたことによる影響を小さく抑えることができる。また、このような構成によれば、非駆動ローラ１４ａが異常検出に基づいて自動で退避されるため、対処動作としての非駆動ローラ１４ａの退避をより迅速に実行させることができる。   In this respect, in this configuration, when a rotation abnormality is detected, the non-driving roller 14a is retracted from the glass ribbon G by driving the retracting drive unit 25, so that the glass ribbon G is scattered by the non-driving roller 14a in which the rotation abnormality has occurred. It is possible to avoid such a situation, and it is possible to reduce the influence caused by the rotation abnormality occurring in the non-driving roller 14a. Further, according to such a configuration, since the non-driving roller 14a is automatically retracted based on the abnormality detection, the non-driving roller 14a can be evacuated more quickly as a coping operation.

なお、上記では、制御部２０からの異常検出信号に基づいて対処動作を行う対処部として報知部２２と退避駆動部２５の両方を備えた構成を説明したが、報知部２２を備えずに退避駆動部２５のみを対処部として備えた構成としてもよい。   In the above description, the configuration in which both the notification unit 22 and the retraction drive unit 25 are provided as the coping unit that performs the coping operation based on the abnormality detection signal from the control unit 20 has been described. It is good also as a structure provided only with the drive part 25 as a countermeasure part.

・上記実施形態では、制御部２０は、回転検出部２１の出力信号から算出した非駆動ローラ１４ａの回転速度に基づいて非駆動ローラ１４ａの回転異常を検出するが、これ以外に例えば、回転検出部２１の出力信号から算出した非駆動ローラ１４ａの回転加速度に基づいて該非駆動ローラ１４ａの回転異常を検出するようにしてもよい。また、第１駆動ローラ１３と非駆動ローラ１４ａとの回転速度差（又は速度比率）、又は第２駆動ローラ１５と非駆動ローラ１４ａとの回転速度差（又は速度比率）に基づいて該非駆動ローラ１４ａの回転異常を検出するようにしてもよい。なお、複数の駆動ローラが設けられている場合、非駆動ローラ１４ａとの距離が最も近い駆動ローラの回転速度と、非駆動ローラ１４ａの回転速度とを比較して回転異常を検出することが好ましい。ローラ間の距離が近いほど正常時の回転速度が近くなり、異常状態を、より容易かつ正確に検出し易くなる。   In the above embodiment, the control unit 20 detects the rotation abnormality of the non-driving roller 14a based on the rotation speed of the non-driving roller 14a calculated from the output signal of the rotation detection unit 21, but other than this, for example, rotation detection The rotation abnormality of the non-driving roller 14a may be detected based on the rotational acceleration of the non-driving roller 14a calculated from the output signal of the unit 21. Further, the non-driving roller based on the rotational speed difference (or speed ratio) between the first driving roller 13 and the non-driving roller 14a or the rotational speed difference (or speed ratio) between the second driving roller 15 and the non-driving roller 14a. The rotation abnormality 14a may be detected. In the case where a plurality of drive rollers are provided, it is preferable to detect rotation abnormality by comparing the rotation speed of the drive roller closest to the non-drive roller 14a with the rotation speed of the non-drive roller 14a. . The closer the distance between the rollers is, the closer the normal rotation speed is, and it becomes easier to detect an abnormal state more easily and accurately.

・また、上記実施形態では、回転検出部２１及び制御部２０にて非駆動ローラ１４ａの回転異常を検出し、その回転異常の検出に基づいて制御部２０が報知部２２に異常検出信号を出力するが、これに特に限定されるものではない。例えば、非駆動ローラ１４ａの変位異常を検出し、その変位異常の検出に基づいて制御部２０が報知部２２に異常検出信号を出力するようにしてもよい。   In the above embodiment, the rotation detection unit 21 and the control unit 20 detect a rotation abnormality of the non-driving roller 14a, and the control unit 20 outputs an abnormality detection signal to the notification unit 22 based on the detection of the rotation abnormality. However, it is not particularly limited to this. For example, a displacement abnormality of the non-driving roller 14a may be detected, and the control unit 20 may output an abnormality detection signal to the notification unit 22 based on the detection of the displacement abnormality.

この場合の一例を図２に示す。同図の例では、非駆動ローラ１４ａの変位異常を検出するための手段として、ＣＣＤやＣＭＯＳ等の撮像素子を有するカメラからなる撮像部３１を備えている。撮像部３１は非駆動ローラ１４ａ（及び回転軸）の一部又は全体を撮像し、その撮像した画像データを制御部２０に出力する。制御部２０は、撮像部３１により得られた画像データに基づいて非駆動ローラ１４ａの変位特性値（例えば、非駆動ローラ１４ａの位置情報）を算出する。そして、制御部２０は、算出した非駆動ローラ１４ａの変位特性値に基づいて非駆動ローラ１４ａの変位（位置）が異常か否かを判定し、異常が生じていると判定した場合、報知部２２に異常検出信号を出力する。   An example of this case is shown in FIG. In the example shown in the figure, an image pickup unit 31 composed of a camera having an image pickup device such as a CCD or CMOS is provided as means for detecting a displacement abnormality of the non-driving roller 14a. The imaging unit 31 images a part or the whole of the non-driving roller 14 a (and the rotation shaft), and outputs the captured image data to the control unit 20. The control unit 20 calculates a displacement characteristic value of the non-driving roller 14a (for example, position information of the non-driving roller 14a) based on the image data obtained by the imaging unit 31. Then, the control unit 20 determines whether or not the displacement (position) of the non-driving roller 14a is abnormal based on the calculated displacement characteristic value of the non-driving roller 14a. 22 outputs an abnormality detection signal.

この構成によれば、例えば、非駆動ローラ１４ａに軸ぶれが生じている場合等に、制御部２０にて算出される非駆動ローラ１４ａの変位特性値が異常値を示し、制御部２０から報知部２２に異常検出信号が出力される。そして、その異常検出信号に基づいて報知部２２のディスプレイ２３及びスピーカ２４にて非駆動ローラ１４ａの変位異常の報知が実行される。これにより、非駆動ローラ１４ａに軸ぶれ等の変位異常が生じて所望のガラスリボンＧが形成されないといった状況を、報知部２２による報知によって作業者が迅速に把握することができる。   According to this configuration, for example, when the shaft blurring occurs in the non-driving roller 14a, the displacement characteristic value of the non-driving roller 14a calculated by the control unit 20 shows an abnormal value, and notification from the control unit 20 An abnormality detection signal is output to the unit 22. Based on the abnormality detection signal, the display 23 and the speaker 24 of the notification unit 22 notify the displacement abnormality of the non-driving roller 14a. As a result, the operator can quickly grasp the situation in which a desired glass ribbon G is not formed due to a displacement abnormality such as shaft runout in the non-driving roller 14a by the notification by the notification unit 22.

なお、図２に示す例では、非駆動ローラ１４ａの変位異常を検出するための手段とし撮像部３１を備えたが、これに特に限定されるものではなく、例えば、接触式変位センサや光学式等の非接触変位センサによって非駆動ローラ１４ａ（又は回転軸）の変位異常を検出してもよい。   In the example shown in FIG. 2, the imaging unit 31 is provided as a means for detecting a displacement abnormality of the non-driving roller 14a. However, the present invention is not particularly limited to this. For example, a contact displacement sensor or an optical type is provided. An abnormal displacement of the non-driving roller 14a (or the rotating shaft) may be detected by a non-contact displacement sensor such as.

また、図２に示す例では、非駆動ローラ１４ａ，１４ｂのうちの非駆動ローラ１４ａの変位異常を撮像部３１にて検出しているが、非駆動ローラ１４ｂの変位異常、又は非駆動ローラ１４ａ，１４ｂ両方の変位異常を検出する構成としてもよい。   In the example shown in FIG. 2, the displacement abnormality of the non-driving roller 14a among the non-driving rollers 14a and 14b is detected by the imaging unit 31, but the displacement abnormality of the non-driving roller 14b or the non-driving roller 14a is detected. , 14b may be configured to detect displacement anomalies.

また、例えば、図３に示すように、非駆動ローラ１４ａに内蔵した温度センサ３２にて該非駆動ローラ１４ａの温度異常を検出し、その温度異常の検出に基づいて報知部２２に異常検出信号が出力されるようにしてもよい。なお、非駆動ローラ１４ａに温度異常が生じる状態では、ガラスリボンＧの所望の形状が形成されないといった状況となる。このことは、非駆動ローラ１４ａがガラスリボンＧの幅方向端部を冷却する冷却ローラである場合は特に顕著となる。   For example, as shown in FIG. 3, a temperature sensor 32 built in the non-driving roller 14a detects a temperature abnormality of the non-driving roller 14a, and an abnormality detection signal is sent to the notification unit 22 based on the detection of the temperature abnormality. It may be output. In the state where the temperature abnormality occurs in the non-driving roller 14a, the desired shape of the glass ribbon G is not formed. This is particularly noticeable when the non-driving roller 14a is a cooling roller that cools the end of the glass ribbon G in the width direction.

このような構成によれば、温度センサ３２にて測定される非駆動ローラ１４ａの温度が異常値を示し、制御部２０から報知部２２に異常検出信号が出力されると、その異常検出信号に基づいて報知部２２のディスプレイ２３及びスピーカ２４にて非駆動ローラ１４ａの温度異常の報知が実行される。これにより、非駆動ローラ１４ａの温度異常によって所望のガラスリボンＧが形成されないといった状況を、報知部２２による報知によって作業者が迅速に把握することができる。   According to such a configuration, when the temperature of the non-driving roller 14a measured by the temperature sensor 32 indicates an abnormal value and an abnormality detection signal is output from the control unit 20 to the notification unit 22, the abnormality detection signal Based on this, the display 23 and the speaker 24 of the notification unit 22 notify the temperature abnormality of the non-driving roller 14a. Thereby, the operator can quickly grasp the situation where the desired glass ribbon G is not formed due to the temperature abnormality of the non-driving roller 14a by the notification by the notification unit 22.

なお、非駆動ローラ１４ａに軸ぶれや温度異常が生じた場合には、非駆動ローラ１４ａの回転速度が変動する傾向があるため、上記実施形態のように回転速度の異常を検知する構成でも非駆動ローラ１４ａの軸ぶれや温度異常に対応できる。   Note that, when shaft shake or temperature abnormality occurs in the non-driving roller 14a, the rotational speed of the non-driving roller 14a tends to fluctuate. It is possible to cope with shaft runout and temperature abnormality of the drive roller 14a.

また、図３に示す例では、非駆動ローラ１４ａ，１４ｂのうちの非駆動ローラ１４ａの温度異常を温度センサ３２にて検出しているが、非駆動ローラ１４ｂの温度異常、又は非駆動ローラ１４ａ，１４ｂ両方の温度異常を検出する構成としてもよい。   In the example shown in FIG. 3, the temperature abnormality of the non-driving roller 14a among the non-driving rollers 14a and 14b is detected by the temperature sensor 32. However, the temperature abnormality of the non-driving roller 14b or the non-driving roller 14a is detected. , 14b may be configured to detect temperature abnormalities.

・上記実施形態では、制御部２０からの異常検出信号に基づいてスピーカ２４から警報音を発生させるとともに、非駆動ローラ１４ａの回転に異常が発生した旨の警告情報をディスプレイ２３に表示させるようにしたが、報知部２２による報知の態様はこれに限定されるものではなく、例えば、警告灯の点灯によって報知するように構成してもよい。   In the above embodiment, an alarm sound is generated from the speaker 24 based on the abnormality detection signal from the control unit 20, and warning information indicating that an abnormality has occurred in the rotation of the non-driving roller 14a is displayed on the display 23. However, the mode of notification by the notification unit 22 is not limited to this, and for example, the notification unit 22 may be configured to notify by turning on a warning lamp.

・上記実施形態では、非駆動ローラ１４ａの状態異常（上記実施形態では回転異常）を報知部２２にて報知可能に構成されたが、これ以外に例えば、第１及び第２駆動ローラ１３，１５の少なくとも一方の状態異常（例えば回転異常）を報知部２２にて報知可能に構成してもよい。また、非駆動ローラ１４ａ及び第１及び第２駆動ローラ１３，１５の全ての状態異常を報知部２２にて報知可能に構成してもよい。   In the above embodiment, the notification unit 22 is configured to notify the abnormality of the state of the non-driving roller 14a (rotation abnormality in the above embodiment), but other than this, for example, the first and second driving rollers 13, 15 The notification unit 22 may be configured to notify at least one state abnormality (for example, rotation abnormality). In addition, the notification unit 22 may be configured to notify all the abnormal states of the non-driving roller 14a and the first and second driving rollers 13 and 15.

・上記実施形態では、成形部１２の下方において上流側から順に第１駆動ローラ１３、非駆動ローラ１４ａ，非駆動ローラ１４ｂ及び第２駆動ローラ１５が配置されたローラ構成としているが、成形部１２の下方におけるローラ構成は上記実施形態に限定されるものではなく、構成に応じて適宜変更してもよい。また、上記実施形態では各第２駆動ローラ１５がガラスリボンＧの表面側及び裏面側でそれぞれ１本の回転軸１７によって一体回転する例を示したが、これ以外に例えば、各第２駆動ローラ１５を個別の回転軸により所謂片持ち状態で回転させてもよい。   In the above embodiment, the first driving roller 13, the non-driving roller 14 a, the non-driving roller 14 b, and the second driving roller 15 are arranged in order from the upstream side below the molding unit 12. The roller configuration below is not limited to the above embodiment, and may be changed as appropriate according to the configuration. In the above-described embodiment, the example in which each second driving roller 15 is integrally rotated by one rotating shaft 17 on the front surface side and the back surface side of the glass ribbon G has been described. 15 may be rotated in a so-called cantilever state by an individual rotating shaft.

・上記実施形態では、ガラス物品の製造装置１１は、ダウンドロー法を用いてガラスリボンＧを成形する成形部１２を備えているが、ダウンドロー法に限定されず、ガラスを流下成形する成形部に変更することもできる。   In the above-described embodiment, the glass article manufacturing apparatus 11 includes the molding unit 12 that molds the glass ribbon G using the downdraw method, but is not limited to the downdraw method, and a molding unit that molds the glass downward. It can also be changed.
