Description

摩擦材の加熱装置および加熱方法Friction material heating device and heating method
　本発明は、摩擦材の加熱装置および加熱方法に関する。 The present invention relates to a friction material heating device and a heating method.
　車両やその他各種の機械で用いられるブレーキには、通常、摩擦材が備わっている。摩擦材は、運動エネルギーを熱エネルギーに変換する部材なので、複数回連続して制動すると摩擦面が高温になり、所望の効き性能が発揮されるようになる。そこで、摩擦材の製造ラインでは、初期フェード対策として、出荷前に予め摩擦面を加熱する処置が行われる（特許文献１－２を参照）。 Brakes used in vehicles and other various machines are usually equipped with friction materials. Since the friction material is a member that converts kinetic energy into thermal energy, the friction surface becomes hot when braking continuously for a plurality of times, and desired effectiveness performance is exhibited. Therefore, in the friction material production line, as a countermeasure against initial fading, a pretreatment is performed to heat the friction surface before shipping (see Patent Document 1-2).

　摩擦材の摩擦面を加熱する温度や時間などの条件は、製品の種別毎に異なる。よって、様々な種類の摩擦材を取り扱う製造ラインでは、加熱する摩擦材の種類に応じた加熱温度や加熱時間の管理が行われる。加熱温度や加熱時間の管理手法としては、例えば、摩擦材のサンプルを試験的に加熱して得た摩擦材の種類と適正な加熱時間との相関関係に従い、加熱時間を調整する手法が挙げられる。しかし、当該手法は、加熱した摩擦面の状態を直接確認する手法ではないため、コンベア等に複数ワークが並んだ搬送状態においてワークそれぞれの個別計量をすることが出来ず、出荷する摩擦材の摩擦面が適正に加熱されていることを正確に把握することは困難である。 ¡Conditions such as temperature and time for heating the friction surface of the friction material differ depending on the product type. Therefore, in a production line that handles various types of friction materials, management of the heating temperature and the heating time according to the type of friction material to be heated is performed. As a management method of the heating temperature and the heating time, for example, there is a method of adjusting the heating time according to the correlation between the type of friction material obtained by experimentally heating the friction material sample and the appropriate heating time. . However, since this method is not a method for directly checking the state of the heated friction surface, it is not possible to individually measure each workpiece in a conveying state where a plurality of workpieces are arranged on a conveyor or the like, and the friction of the friction material to be shipped It is difficult to accurately grasp that the surface is properly heated.
　そこで、本発明は、摩擦材の摩擦面をワーク毎に適正に加熱可能にすることを解決課題とする。 Therefore, an object of the present invention is to enable heating of the friction surface of the friction material appropriately for each workpiece.
　上記課題を解決するため、本発明では、摩擦材の重量変化を測定しながら加熱することにした。 In order to solve the above problems, in the present invention, heating was performed while measuring the change in the weight of the friction material.
　詳細には、本発明は、ブレーキ用摩擦材の表面を加熱する摩擦材の加熱装置であって、摩擦材の表面を加熱する加熱手段と、前記加熱手段で加熱する際に摩擦材が支持される部位を形成する摩擦材支持部と、摩擦材支持部に支持される摩擦材の重量変化を測定する計量部と、を備える。 More specifically, the present invention relates to a friction material heating device for heating the surface of a friction material for a brake, the heating means for heating the surface of the friction material, and the friction material being supported when heated by the heating means. A friction material support portion that forms a portion to be measured, and a measuring portion that measures a change in weight of the friction material supported by the friction material support portion.
　上記の加熱装置によれば、摩擦材支持部に支持された摩擦材の重量変化を測定することができる。よって、摩擦材の加熱中に摩擦材の重量変化を監視すれば、加熱に伴う摩擦材の重量変化を基に、摩擦材の焼き度合いをワーク毎に定量的に把握することができる。摩擦材の焼き度合いをワーク毎に定量的に把握することができれば、摩擦材の摩擦面をワーク毎に適正に加熱することが可能になる。 According to the above heating device, the weight change of the friction material supported by the friction material support portion can be measured. Therefore, if the weight change of the friction material is monitored during the heating of the friction material, the degree of baking of the friction material can be quantitatively grasped for each workpiece based on the weight change of the friction material accompanying the heating. If the degree of baking of the friction material can be grasped quantitatively for each workpiece, the friction surface of the friction material can be appropriately heated for each workpiece.
　なお、摩擦材支持部は、摩擦材を上端で支持する支柱を有し、計量部は、支柱から受ける荷重を基に摩擦材の重量変化を測定するものであってもよい。摩擦材支持部がこのように構成されていれば、計量部が受ける熱の影響を抑制することができる。 The friction material support portion may have a support column that supports the friction material at the upper end, and the measuring unit may measure a change in the weight of the friction material based on a load received from the support column. If the friction material support portion is configured in this way, the influence of heat received by the measuring portion can be suppressed.
　また、上記加熱装置は、摩擦材の重量変化が所定量に達したことを計量部で検知すると、摩擦材の加熱を停止する制御部を更に備えるものであってもよい。摩擦材の加熱を停止する手法としては、例えば、加熱手段の停止、加熱手段からの摩擦材の離間、及び、摩擦材に対する空気の吹き付けのうち少なくとも何れかの手法が挙げられる。このような制御部が備わっていれば、摩擦材への加熱を自動的に止められるので、人為的な加熱不良を防ぐことができる。 The heating device may further include a control unit that stops heating the friction material when the weighing unit detects that the weight change of the friction material has reached a predetermined amount. Examples of the method for stopping the heating of the friction material include at least one of a method for stopping the heating unit, a separation of the friction material from the heating unit, and a blowing of air to the friction material. If such a control unit is provided, the heating to the friction material can be automatically stopped, so that artificial heating failure can be prevented.
　また、本発明は、方法の側面から捉えることもできる。例えば、本発明は、ブレーキ用摩擦材の表面を加熱する摩擦材の加熱方法であって、加熱手段によって表面が焼かれていく状態の摩擦材の重量変化を監視し、重量変化に基づいて、加熱手段による摩擦材の加熱を停止するものであってもよい。 The present invention can also be understood from the aspect of the method. For example, the present invention is a friction material heating method for heating the surface of a friction material for a brake, monitoring the change in weight of the friction material in a state where the surface is baked by the heating means, and based on the change in weight, The heating of the friction material by the heating means may be stopped.
　本発明であれば、摩擦材の摩擦面をワーク毎に適正に加熱することが可能となる。 In the present invention, the friction surface of the friction material can be appropriately heated for each workpiece.

The embodiment described below exemplifies one aspect of the present invention, and the technical scope of the present invention is not limited to the following aspect.
　図１は、摩擦材の加熱装置の概略構成図である。加熱装置１は、ディスクブレーキの摩擦材の摩擦面を加熱する装置であり、摩擦材の製造において行われるいわゆる表面焼なる工程で用いられる装置である。加熱装置１は、図１に示すように、加熱炉２、加熱器３（「加熱手段」の一例）、支柱４、計量装置６、制御装置８を備える。 FIG. 1 is a schematic configuration diagram of a friction material heating apparatus. The heating device 1 is a device that heats the friction surface of the friction material of the disc brake, and is a device that is used in a so-called surface baking process performed in the manufacture of the friction material. As shown in FIG. 1, the heating device 1 includes a heating furnace 2, a heater 3 (an example of “heating means”), a support column 4, a weighing device 6, and a control device 8.
　加熱炉２は、摩擦材９の摩擦面を加熱するスペースを内部に形成する炉であり、煙や臭気の飛散を防ぐことも可能で、摩擦材９を収容可能な大きさを有する。加熱炉２は、摩擦材９を出し入れするための出入口７を側面に有する。よって、摩擦材９を加熱炉２の側方から出し入れ可能である。また、加熱炉２の底部には、支柱４が通る孔５が設けられている。 The heating furnace 2 is a furnace in which a space for heating the friction surface of the friction material 9 is formed, and it is possible to prevent scattering of smoke and odors, and has a size that can accommodate the friction material 9. The heating furnace 2 has an entrance / exit 7 for taking in and out the friction material 9 on a side surface. Therefore, the friction material 9 can be taken in and out from the side of the heating furnace 2. Further, a hole 5 through which the support column 4 passes is provided at the bottom of the heating furnace 2.

　支柱４は、摩擦材９を支柱上端４Ｓ（「摩擦材支持部」の一例）で支持する棒状の部材であり、下端が計量装置６に固定されている。支柱４は、加熱炉２の孔５に挿通されている。よって、治具１０に載置された摩擦材９が支柱上端４Ｓに載ると、治具１０と摩擦材９の重量が計量装置６に加わる。支柱４は、適当な長さを有する棒状体であるため、計量装置６に伝わる加熱器３の熱量を抑制し、保護する機能を兼ね備える。 The support column 4 is a rod-like member that supports the friction material 9 with an upper end 4S of the support column (an example of a “friction material support portion”), and the lower end is fixed to the measuring device 6. The support column 4 is inserted into the hole 5 of the heating furnace 2. Therefore, when the friction material 9 placed on the jig 10 is placed on the support upper end 4 </ b> S, the weight of the jig 10 and the friction material 9 is added to the weighing device 6. Since the support | pillar 4 is a rod-shaped body which has a suitable length, it has the function to suppress and protect the calorie | heat amount of the heater 3 transmitted to the weighing | measuring apparatus 6.

The weighing device 6 can measure a change in the weight of the friction material 9 due to carbonization or evaporation of moisture due to heating of the friction material 9.

In addition, when the operator of the heating apparatus 1 controls the heater 3 manually, the control apparatus 8 can be omitted.
　図２は、摩擦材９を動かす機構を示した図である。加熱装置１は、出入口７を通じて加熱炉２の内外へ摩擦材９を出し入れする出し入れ装置１１と、支柱４が固定された計量装置６を上下に昇降する昇降装置１２とを備える。出し入れ装置１１は、治具１０を横方向へスライド可能なレール１１ａ，１１ｂを有する。また、出し入れ装置１１には、レール１１ａ，１１ｂに載った治具１０をレール１１ａ，１１ｂの長手方向沿いに動かす図示しない駆動機構が備わっている。昇降装置１２は、計量装置６を昇降させるためのシリンダ１２ｂ、シリンダ１２ｂに嵌るピストン１２ｃ、ピストン１２ｃの上端に固定されるプレート１２ｄを備える。計量装置６は、プレート１２ｄに固定されている。昇降装置１２が作動すると、ピストン１２ｃが押し上げられてプレート１２ｄが上昇したり、ピストン１２ｃが引き下げられてプレート１２ｄが下降したりする。出し入れ装置１１や昇降装置１２は、制御装置８に制御されてもよいし、或いは、その他の制御装置に制御されてもよい。 FIG. 2 is a view showing a mechanism for moving the friction material 9.

The taking-out apparatus 11 has rails 11a and 11b that can slide the jig 10 in the lateral direction. In addition, the loading / unloading device 11 includes a driving mechanism (not shown) that moves the jig 10 mounted on the rails 11a and 11b along the longitudinal direction of the rails 11a and 11b. The lifting device 12 includes a cylinder 12b for lifting and lowering the weighing device 6, a piston 12c fitted to the cylinder 12b, and a plate 12d fixed to the upper end of the piston 12c.

　図３は、加熱装置１において実現される動作内容を示したフローチャートである。以下、加熱装置１において実現される動作内容について説明する。なお、以下に説明する加熱装置１の動作内容は、制御装置８あるいはその他の制御装置で自動的に実現される。さらに一部または全部の動作内容が手動で実現されてもよい。 FIG. 3 is a flowchart showing the operation content realized in the heating apparatus 1. Hereinafter, the operation content realized in the heating apparatus 1 will be described. The operation content of the heating device 1 described below is automatically realized by the control device 8 or another control device. Furthermore, part or all of the operation content may be realized manually.
　加熱装置１においては、まず、摩擦材９を治具１０に載せた状態のままで加熱炉２の内部へ移送する動作が出し入れ装置１１によって行われる（Ｓ１０１）。次に、昇降装置１２が僅かに作動して計量装置６が上昇し、摩擦材９を載せた治具１０が支柱４に支持された状態になると、計量装置６が出力する計測値の基準点の確認が行われる（Ｓ１０２）。基準点の確認は、いわゆるゼロ点調整であってもよいし、単なる計測値の記録であってもよい。計量装置６が出力する計測値の基準点の確認が行われた後、摩擦材９の加熱が開始される（Ｓ１０３）。すなわち、加熱器３がオンになり、昇降装置１２が作動して計量装置６が上昇し、摩擦材９が加熱器３の付近へ移動する。加熱器３がオンの状態で摩擦材９が加熱器３の付近へ配置されると、摩擦材９の摩擦面が焼け始める。摩擦材９の摩擦面が焼け始めると、摩擦材９の摩擦面で加熱による炭化や水分の蒸発が行われ、摩擦材９の質量が低下する。摩擦材９の質量が低下すると、計量装置６によって計測される摩擦材９の重量の計測値が下がる（Ｓ１０４）。摩擦材９の重量変化が所定量に達すると摩擦材９の加熱が停止される（Ｓ１０５）。すなわち、加熱器３がオフになり、昇降装置１２が作動して計量装置６が下降し、摩擦材９を載せた治具１０が再びレール１１ａ，１１ｂに載る。なお、所定量とは、摩擦材９の摩擦面が設計上のブレーキ性能を使用開始初期から発揮できるように設定される摩擦材９の焼き減量であり、例えば、製品毎に予め適宜設定される。摩擦材９の加熱が停止された後は、摩擦材９を治具１０に載せた状態のままで加熱炉２の外部へ移送する動作が出し入れ装置１１によって行われる（Ｓ１０６）。 In the heating device 1, firstly, an operation of transferring the friction material 9 to the inside of the heating furnace 2 while being placed on the jig 10 is performed by the loading / unloading device 11 (S <b> 101). Next, when the lifting / lowering device 12 operates slightly to raise the weighing device 6 and the jig 10 on which the friction material 9 is placed is supported by the support column 4, the reference point of the measurement value output by the weighing device 6 Is confirmed (S102). The confirmation of the reference point may be a so-called zero point adjustment or may be a simple measurement value recording. After the reference point of the measurement value output from the weighing device 6 is confirmed, heating of the friction material 9 is started (S103). That is, the heater 3 is turned on, the lifting device 12 is operated, the weighing device 6 is raised, and the friction material 9 is moved to the vicinity of the heater 3. When the friction material 9 is disposed in the vicinity of the heater 3 with the heater 3 turned on, the friction surface of the friction material 9 starts to burn. When the friction surface of the friction material 9 starts to burn, carbonization or evaporation of moisture by heating is performed on the friction surface of the friction material 9, and the mass of the friction material 9 is reduced. When the mass of the friction material 9 decreases, the measured value of the weight of the friction material 9 measured by the weighing device 6 decreases (S104). When the weight change of the friction material 9 reaches a predetermined amount, heating of the friction material 9 is stopped (S105). That is, the heater 3 is turned off, the elevating device 12 is operated, the measuring device 6 is lowered, and the jig 10 on which the friction material 9 is placed is placed on the rails 11a and 11b again. The predetermined amount is a burn-out amount of the friction material 9 that is set so that the friction surface of the friction material 9 can exhibit the designed brake performance from the beginning of use. For example, the predetermined amount is appropriately set in advance for each product. . After the heating of the friction material 9 is stopped, an operation for transferring the friction material 9 to the outside of the heating furnace 2 while being placed on the jig 10 is performed by the loading / unloading device 11 (S106).
　図４（Ａ）～図４（Ｃ）は、出し入れ装置１１及び昇降装置１２の動作内容を示した図である。上述のステップＳ１０１においては、図４（Ａ）に示されるように、摩擦材９を治具１０に載せた状態のままで加熱炉２の内部へ移送する動作が出し入れ装置１１によって行われる。また、上述のステップＳ１０２においては、計量装置６が僅かに上昇することにより、摩擦材９を載せた治具１０が支柱４に支持された状態になる。また、上述のステップＳ１０４においては、図４（Ｃ）に示されるように、計量装置６が上昇して摩擦材９が加熱器３の付近へ移動する動作が昇降装置１２によって行われる。 4 (A) to 4 (C) are diagrams showing the operation contents of the loading / unloading device 11 and the lifting device 12. In step S <b> 101 described above, as shown in FIG. 4A, an operation for transferring the friction material 9 to the inside of the heating furnace 2 while being placed on the jig 10 is performed by the loading / unloading device 11. Further, in the above-described step S102, the jig 10 on which the friction material 9 is placed is supported by the support column 4 by slightly raising the measuring device 6. Further, in step S104 described above, as shown in FIG. 4C, the lifting device 12 performs an operation in which the weighing device 6 moves up and the friction material 9 moves to the vicinity of the heater 3.
　図５は、加熱器３で摩擦材９を焼いている際に計量装置６で観測される重量の指示値の変化を示した図である。摩擦材９の加熱が開始されると、摩擦材９の摩擦面が焼け始める。摩擦材９の摩擦面が焼け始めると、摩擦材９の摩擦面で加熱による炭化や水分の蒸発が行われるため、摩擦材９の質量が低下する。摩擦材９の質量が低下すると、図５に示されるように、計量装置６によって計測される摩擦材９の重量の計測値が下がる。摩擦材９の焼き減量が所定の適当な管理幅の範囲内に達し、摩擦材９の加熱が停止された後も、摩擦材９の重量の低下は、摩擦材９の自燃や残留熱による水分の揮散により暫く継続することもある。よって、例えば、焼き減量による摩擦材９の重量低下が適当なところで、出し入れ装置１１やその他の搬送ロボットが摩擦材９を取り出すようにすることで、摩擦材９を加熱炉２の周囲の空気に曝して冷却し、自燃や残留熱による摩擦材９の重量の降下を速やかに停止あるいは抑制することが好ましい。 FIG. 5 is a diagram showing a change in the indicated value of the weight observed by the weighing device 6 when the friction material 9 is baked by the heater 3. When heating of the friction material 9 is started, the friction surface of the friction material 9 starts to burn. When the friction surface of the friction material 9 starts to burn, carbonization or moisture evaporation due to heating is performed on the friction surface of the friction material 9, so that the mass of the friction material 9 is reduced. When the mass of the friction material 9 is lowered, as shown in FIG. 5, the measured value of the weight of the friction material 9 measured by the measuring device 6 is decreased. Even after the amount of burn-out of the friction material 9 has reached the range of a predetermined appropriate control width and the heating of the friction material 9 is stopped, the decrease in the weight of the friction material 9 is due to the self-combustion of the friction material 9 and moisture due to residual heat. It may continue for a while due to volatilization. Therefore, for example, when it is appropriate to reduce the weight of the friction material 9 due to the amount of burning loss, the friction material 9 is taken into the air around the heating furnace 2 by taking out the friction material 9 by the loading / unloading device 11 and other transport robots. It is preferable to cool by exposure to quickly stop or suppress a decrease in the weight of the friction material 9 due to self-combustion or residual heat.
　なお、図５では、加熱開始後、摩擦材９の重量が上昇することなく低下している。しかし、例えば、加熱器３がガスバーナーの場合、摩擦材９が火炎の圧力を受ける為、加熱開始後、摩擦材９の重量が一旦上昇した後に低下する傾向が現れることもある。 In FIG. 5, the weight of the friction material 9 decreases without increasing after the start of heating. However, for example, when the heater 3 is a gas burner, the friction material 9 receives the pressure of the flame, so that after the heating is started, there is a tendency that the weight of the friction material 9 once increases and then decreases.
　上記実施形態の加熱装置１を用いれば、摩擦材９の摩擦面の焼き度合いを摩擦材９の重量に基づいて定量的に把握することができるため、経験的に設定された規定の加熱時間に沿って焼く場合に比べて摩擦面を適正に焼くことができる。よって、例えば、雰囲気温度の変化や加熱器３の劣化といった各種要因に伴う加熱不良を抑制し、歩留まりの向上が図られる。また、上記実施形態の加熱装置１を用いれば、摩擦材９の摩擦面の焼き度合いを摩擦材９のワーク毎に把握することができる。摩擦材９の摩擦面の焼き度合いを摩擦材９のワーク毎に把握することができると、ワーク毎に適正な加熱を実現することができるため、製品種別毎にも対応することができる。ここで、製品種別毎とは、ライニング部分の面積、厚み、ライニングを構成する材料の特性の違いを指している。製品種別毎の対応が可能であれば、例えば、加熱装置１が多品種少量生産のラインに用いられる場合に有利である。また、個別の品質管理にも有効である。 If the heating device 1 of the above-described embodiment is used, the degree of baking of the friction surface of the friction material 9 can be quantitatively grasped based on the weight of the friction material 9, so that the specified heating time is set empirically. The friction surface can be properly baked as compared with the case of baking along. Therefore, for example, defective heating due to various factors such as change in ambient temperature and deterioration of the heater 3 can be suppressed, and the yield can be improved. Moreover, if the heating apparatus 1 of the said embodiment is used, the baking degree of the friction surface of the friction material 9 can be grasped | ascertained for every workpiece | work of the friction material 9. FIG. If the degree of baking of the friction surface of the friction material 9 can be grasped for each workpiece of the friction material 9, appropriate heating can be realized for each workpiece, and therefore, it can be handled for each product type. Here, each product type refers to the difference in the area of the lining portion, the thickness, and the characteristics of the materials constituting the lining. If it is possible to cope with each product type, for example, it is advantageous when the heating device 1 is used in a line for multi-product and small-quantity production. It is also effective for individual quality control.
　なお、上記実施形態では、加熱炉２の中に１つの摩擦材９が収容されていたが、加熱炉２の中には複数の摩擦材９が収容されてもよい。この場合、計量装置６は、１つの加熱炉２に対し複数備わっていてもよい。 In the above embodiment, one friction material 9 is accommodated in the heating furnace 2, but a plurality of friction materials 9 may be accommodated in the heating furnace 2. In this case, a plurality of weighing devices 6 may be provided for one heating furnace 2.
　また、上記実施形態では、摩擦材９が棒状の支柱４に支持されていたが、加熱器３の熱による支障が計量装置６に無ければ、摩擦材９は棒状の支柱４以外の形態の部材を介して計量装置６に載るようにしてもよい。 Moreover, in the said embodiment, although the friction material 9 was supported by the rod-shaped support | pillar 4, if there is no trouble by the heat | fever of the heater 3 in the measuring device 6, the friction material 9 is a member of forms other than the rod-shaped support | pillar 4 You may make it mount on the weighing | measuring apparatus 6 via.
　また、上記実施形態では、摩擦材９の加熱を止める手段として加熱器３をオフにしていたが、加熱器３をオンにしたまま摩擦材９を加熱器３から離間させることで摩擦材９の加熱を止めるようにしてもよいし、摩擦材９に空気を吹き付けることで加熱を実質的に止めてもよいし、或いは、これらの手法を組み合わせてもよい。 In the above embodiment, the heater 3 is turned off as a means for stopping the heating of the friction material 9. However, the friction material 9 is separated from the heater 3 while the heater 3 is turned on. The heating may be stopped, the heating may be substantially stopped by blowing air on the friction material 9, or these methods may be combined.
　また、上記実施形態では、摩擦材９が棒状の支柱４の上端に載置される形態であったが、摩擦材９は、例えば、支柱４の上端で把持される形態であってもよい。また、上記実施形態では、摩擦材９の摩擦面が上を向いた状態で加熱されていたが、摩擦材９は、例えば、摩擦面が横向きや下向きの状態で加熱されてもよい。この場合、摩擦材９と加熱器３の位置関係は、上記実施形態のように摩擦材９が加熱器３の下方へ配置される形態ではなく、上下関係が逆になったり、或いは横向きに並ぶ形態になったりすることになる。 In the above-described embodiment, the friction material 9 is placed on the upper end of the rod-shaped support 4. However, the friction material 9 may be held on the upper end of the support 4, for example. Moreover, in the said embodiment, although the friction surface of the friction material 9 was heated in the state which faced up, the friction material 9 may be heated in the state where the friction surface is horizontal or downward, for example. In this case, the positional relationship between the friction material 9 and the heater 3 is not a form in which the friction material 9 is disposed below the heater 3 as in the above-described embodiment, but the vertical relationship is reversed or arranged sideways. It will become a form.
　また、上記実施形態では、摩擦材９が加熱炉２の内部で加熱される形態となっていたが、加熱炉２は省略されていてもよい。摩擦材９は、例えば、工場内やその他建物の室内空間において露出した状態で加熱されてもよいし、或いは、簡易的な囲いの中で加熱されてもよい。 In the above embodiment, the friction material 9 is heated inside the heating furnace 2, but the heating furnace 2 may be omitted. The friction material 9 may be heated, for example, in an exposed state in a factory or in an indoor space of a building, or may be heated in a simple enclosure.
　また、上記実施形態では、加熱器３や計量装置６が横移動する形態となっていなかったが、加熱装置１は、例えば、以下のように変形してもよい。図６（Ａ）および図６（Ｂ）は、加熱装置１の各機器の動作内容の変形例を示した図である。加熱装置１の加熱器３は、例えば、図６（Ａ）に示されるように、横方向に移動可能なようにしてもよい。また、加熱装置１の計量装置６は、例えば、図６（Ｂ）に示されるように、横方向に移動可能なようにしてもよい。これらの変形例においては、摩擦材９を出し入れする出し入れ装置１１を省略することも可能である。 In the above embodiment, the heater 3 and the measuring device 6 are not laterally moved. However, the heating device 1 may be modified as follows, for example. FIG. 6A and FIG. 6B are diagrams showing a modification of the operation content of each device of the heating device 1. The heater 3 of the heating device 1 may be movable in the lateral direction as shown in FIG. 6 (A), for example. Further, the weighing device 6 of the heating device 1 may be movable in the horizontal direction as shown in FIG. 6B, for example. In these modified examples, it is also possible to omit the taking in / out device 11 for taking in and out the friction material 9.
