Description

本発明はロールプレス装置の軸受冷却機構および軸受冷却方法並びにロールプレス装置に関する。   The present invention relates to a bearing cooling mechanism and a bearing cooling method for a roll press device, and a roll press device.

電極材料の生産を向上させるために、ロールプレス装置の高速化・連続化が望まれている。しかし、高速化・連続化を図ると、長時間の連続運転時に軸受部の機械摩擦により発生した熱がロールに伝わることでロール両端部が熱変形するサーマルクラウンが発生する。サーマルクラウンによるロールの変形量は小さいが、薄膜材を対象としているロールプレス装置においては、サーマルクラウンは、成形後の材料の板厚分布が不均一となる原因となり影響が大きい。このため、軸受部の冷却をいかに低コストで高効率に行うかが課題となっている。   In order to improve the production of electrode materials, there is a demand for a high-speed and continuous roll press device. However, when the speed is increased and the operation speed is increased, heat generated by mechanical friction of the bearing portion is transmitted to the roll during continuous operation for a long time, so that a thermal crown is generated in which both ends of the roll are thermally deformed. Although the amount of deformation of the roll due to the thermal crown is small, in a roll press apparatus for a thin film material, the thermal crown causes a non-uniform thickness distribution of the formed material, and has a large influence. For this reason, how to cool the bearing part efficiently at low cost has been an issue.

二次電池用電極材料のロールプレス装置におけるロール軸受の冷却構造として、特許文献１に記載のものが提案されている。特許文献１には、高速、長時間運転をしても軸受部の機械的摩擦熱により生じるロールの熱変形を防止して、加工精度の高い二次電池用電極材の連続圧縮加工を可能にするため、加圧ロールの軸受を収納保持する軸受箱に熱媒体を流通させてロール軸受の熱を奪う冷却構造が記載されている。なお、二次電池用電極材料のロールプレス装置では、転がり軸受の潤滑として、封入もしくは定期的に追加入れ換えされたグリースで潤滑を行うグリース潤滑方式が主として用いられている。   As a cooling structure of a roll bearing in a roll press device for an electrode material for a secondary battery, one described in Patent Document 1 has been proposed. Patent Literature 1 discloses that the roll can be prevented from being thermally deformed due to the mechanical frictional heat of the bearing portion even when operated at high speed for a long time, thereby enabling continuous compression working of the electrode material for a secondary battery with high working accuracy. For this purpose, there is described a cooling structure in which a heat medium is circulated through a bearing box that houses and holds the bearing of a pressure roll, thereby removing heat from the roll bearing. In a roll press device for an electrode material for a secondary battery, a grease lubrication method for lubricating rolling bearings, in which lubrication is performed with grease that has been sealed or periodically replaced, is mainly used.

特開２０１１−１８１３４８号公報JP 2011-181348 A

近年、電極材料の生産を向上させるために、ロールプレス装置のさらなる高速化及び連続化が望まれている。さらなる高速化・連続化を図る上では、ロール軸受部の冷却をより効果的に行うことが望まれる。   In recent years, in order to improve the production of electrode materials, it has been desired to further increase the speed and continuity of the roll press device. In order to achieve higher speed and continuity, it is desired to cool the roll bearing more effectively.

特許文献１に記載の冷却構造では、軸受箱を冷却するものであり、軸受部の発熱部を間接的に冷却する構造である。発熱部を間接的に冷却する構造となっているため、ロールプレス装置のさらなる高速化及び連続化を図ると、間接冷却では間に合わず、軸受部および軸受箱の温度を効果的に管理することが難しくなることが予想される。   The cooling structure described in Patent Literature 1 cools a bearing housing and indirectly cools a heat generating portion of a bearing portion. Since the heat-generating part is indirectly cooled, if the roll press device is further speeded up and made continuous, the temperature of the bearing part and the bearing box can be effectively managed because the indirect cooling is too late. It is expected to be difficult.

本発明の目的は、ロールプレス装置のさらなる高速化及び連続化を可能とするロールプレス装置の軸受冷却機構および軸受冷却方法並びにロールプレス装置を提供することにある。   An object of the present invention is to provide a bearing cooling mechanism, a bearing cooling method, and a roll press device of a roll press device, which can further increase the speed and make the roll press device continuous.

上記目的を解決するために、本発明は、特許請求の範囲に記載の構成を採用するものである。例えば、本発明は、軸受として転がり軸受を用いたロールプレス装置の軸受冷却機構であって、転がり軸受の潤滑剤として潤滑油を用い、潤滑油の循環ライン上に潤滑油の温度を冷却する温度管理部を備えた潤滑油貯蔵庫を備えたものである。   In order to solve the above-mentioned object, the present invention employs a configuration described in the claims. For example, the present invention relates to a bearing cooling mechanism of a roll press device using a rolling bearing as a bearing, wherein a lubricating oil is used as a lubricant for the rolling bearing, and a temperature for cooling the lubricating oil on a lubricating oil circulation line. A lubricating oil storage provided with a management unit is provided.

本発明によれば、潤滑油に冷却機能を積極的に持たせて発熱部である転がり軸受（軸受部）を直接冷却するようにしているので、ロールプレス装置の軸受部及び軸受箱の温度を効果的に管理することができ、その結果として、ロールプレス装置のさらなる高速化及び連続化が可能となる。
上記した以外の課題、構成及び効果は、以下の実施形態の説明により明らかにされる。 According to the present invention, since the lubricating oil is provided with a cooling function positively to directly cool the rolling bearing (bearing portion) which is a heat generating portion, the temperature of the bearing portion and the bearing box of the roll press device is reduced. It can be managed effectively, and as a result, the speed and continuity of the roll press device can be further increased.
Problems, configurations, and effects other than those described above will be apparent from the following description of the embodiments.

以下、図面を用いて本発明の実施例を詳細に説明する。
図１は本発明のロールプレス装置の軸受冷却機構の概念を示す図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a view showing the concept of a bearing cooling mechanism of the roll press device of the present invention.

ロールプレス機１は、上下に対向配置された一対の加圧ロール（上ロール１０，下ロール１１）と、それらのロール軸２０，２１を支持する転がり軸受（ロール軸受部）３０ａ〜３０ｄと、その転がり軸受を保持する軸受箱４０ａ〜４０ｄと、軸受箱４０ａ〜４０ｄを保持するロールハウジング（図示省略）を備える。ロール軸両端に配置された軸受箱４０ａ〜４０ｄとロールハウジングとの間には、加圧ロール間の間隙調整と加圧調整を行うための例えば油圧シリンダーなどの加圧機構（図示省略）が設けられている。加圧ロール（上ロール１０，下ロール１１）間において二次電池用電極材３がプレス加工される。   The roll press 1 includes a pair of pressure rolls (upper roll 10, lower roll 11) that are vertically opposed to each other, and rolling bearings (roll bearing portions) 30 a to 30 d that support the roll shafts 20 and 21. A bearing box 40a to 40d for holding the rolling bearing and a roll housing (not shown) for holding the bearing box 40a to 40d are provided. A pressurizing mechanism (not shown) such as a hydraulic cylinder for adjusting the gap between pressurizing rolls and pressurizing is provided between the bearing housings 40a to 40d arranged at both ends of the roll shaft and the roll housing. Have been. The secondary battery electrode material 3 is pressed between the pressure rolls (the upper roll 10 and the lower roll 11).

転がり軸受３０ａ〜３０ｄの潤滑には、通常、グリース潤滑方式が採用されているが、本実施例では、油循環潤滑方式を採用している。潤滑油としては、例えば、一般作動油（タービン油：ＩＳＯ ＶＧ ３２など）が用いられる。   Normally, a grease lubrication system is adopted for lubrication of the rolling bearings 30a to 30d. In this embodiment, an oil circulation lubrication system is adopted. As the lubricating oil, for example, general working oil (turbine oil: ISO VG32 or the like) is used.

潤滑油は潤滑油貯蔵庫８０に収容されており、潤滑油供給路５０を介して軸受箱４０ａ内の転がり軸受３０ａに供給される。潤滑油供給路５０上には、ポンプまたは制御弁などからなる潤滑油供給装置５１が設けられ、所定量の潤滑油（例えば、８リットル／分程度）を継続して転がり軸受３０ａに供給する。転がり軸受３０ａを潤滑かつ冷却した後の潤滑油は潤滑油回収路６０を介して潤滑油貯蔵庫８０に回収される。潤滑油回収路６０上には、ポンプまたは制御弁などからなる潤滑油回収装置６１が設けられている。なお、潤滑油供給路５０上および／または潤滑油回収路６０上には、流量計や圧力計などが設置されており（図示省略）、これらの計器を定期的に目視確認し、潤滑油の供給量、排油量、圧力が所定範囲の値になっているか確認できるようにしている。   The lubricating oil is stored in the lubricating oil storage 80 and is supplied to the rolling bearing 30a in the bearing box 40a via the lubricating oil supply path 50. A lubricating oil supply device 51 including a pump or a control valve is provided on the lubricating oil supply passage 50, and continuously supplies a predetermined amount of lubricating oil (for example, about 8 liters / minute) to the rolling bearing 30a. The lubricating oil after lubricating and cooling the rolling bearing 30 a is collected in the lubricating oil storage 80 via the lubricating oil collecting passage 60. A lubricating oil recovery device 61 including a pump or a control valve is provided on the lubricating oil recovery path 60. A flow meter, a pressure gauge, and the like are provided on the lubricating oil supply path 50 and / or the lubricating oil recovery path 60 (not shown). It is possible to check whether the supply amount, the oil discharge amount, and the pressure are within predetermined ranges.

潤滑油供給路５０は、図５に示す給油口５２に接続される。給油口５２は軸受箱４０に形成され、給油口５２から供給された潤滑油は転がり軸受３０に直接供給される。一方、潤滑油回収路６０は図５に示す排油口６２に接続されている。本実施例では、軸受箱４０に排油口６２が二つ形成され、二つの排油口６２から排油された潤滑油が一つの潤滑油回収路６０に合流する。   The lubricating oil supply path 50 is connected to an oil supply port 52 shown in FIG. The oil supply port 52 is formed in the bearing box 40, and the lubricating oil supplied from the oil supply port 52 is directly supplied to the rolling bearing 30. On the other hand, the lubricating oil recovery path 60 is connected to an oil discharge port 62 shown in FIG. In this embodiment, two oil discharge ports 62 are formed in the bearing housing 40, and the lubricating oil discharged from the two oil discharge ports 62 joins one lubricating oil recovery path 60.

本実施例では、排油量（排出量）は、給油量（供給量）よりも、少し多くなるようにしている。例えば、潤滑油供給装置５１、潤滑油回収装置６１のポンプ回転数および／または制御弁開度を制御して、排油量（排出量）＞給油量（供給量）とする。排油量（排出量）と給油量（供給量）の関係は、制御以外に、給油口５２又は潤滑油供給路５０、排油口６２又は潤滑油回収路６０の径や数を調整することにより調整することも可能である。   In this embodiment, the oil discharge amount (discharge amount) is set to be slightly larger than the oil supply amount (supply amount). For example, the pump rotation speed and / or the control valve opening of the lubricating oil supply device 51 and the lubricating oil recovery device 61 are controlled so that the amount of discharged oil (discharged amount)> the amount of supplied oil (supplied amount). The relationship between the oil discharge amount (discharge amount) and the oil supply amount (supply amount) is to adjust the diameter and number of the oil supply port 52 or the lubricating oil supply path 50, the oil discharge port 62, or the lubricating oil recovery path 60 in addition to the control. Can also be adjusted.

このように、給油口５２に加えて排油口６２を軸受箱４０に形成し、排油量（排出量）＞給油量（供給量）とすることにより、軸受部からの油の漏れが抑制可能である。一般的な油循環潤滑方式では、軸受に給油した潤滑油が軸受部から漏れ出し、漏れ出た潤滑油をオイルパンなどで回収し、その潤滑油を集めて循環させている。これでは、プレス加工される電極材への潤滑油の付着の恐れが大きい。本実施例では、そのような潤滑油の付着の恐れを極めて小さくすることができる。なお、プレス加工される電極材への潤滑油の付着の恐れを略なくすように、ロール側と軸受箱との間を分離するようにシール部材などを設けることが望ましい。また、本実施例では、潤滑油の漏れが生じ難い構成であるが、循環する潤滑油の量を確保するために、定期的に（例えば、生産開始時）に潤滑油貯蔵庫８０における潤滑油量を確認し、必要に応じて補充するようにする。   As described above, the oil discharge port 62 is formed in the bearing box 40 in addition to the oil supply port 52, and by setting the oil discharge amount (discharge amount)> the oil supply amount (supply amount), oil leakage from the bearing portion is suppressed. It is possible. In a general oil circulation lubrication system, lubricating oil supplied to a bearing leaks from a bearing portion, the leaked lubricating oil is collected by an oil pan or the like, and the lubricating oil is collected and circulated. In this case, there is a great possibility that lubricating oil will adhere to the electrode material to be pressed. In the present embodiment, the risk of such adhesion of the lubricating oil can be extremely reduced. It is desirable to provide a seal member or the like so as to separate the roll side from the bearing box so as to substantially eliminate the possibility of lubricating oil adhering to the electrode material to be pressed. Further, in the present embodiment, the configuration is such that the leakage of the lubricating oil hardly occurs. However, in order to secure the amount of the circulating lubricating oil, the amount of the lubricating oil in the lubricating oil storage 80 is periodically (for example, at the start of production). Check and replenish if necessary.

そして、本実施例では、軸受箱４０を介して転がり軸受３０に供給する潤滑油の温度を所定の温度に維持するため、次の構成を有する。
軸受箱内の転がり軸受冷却後の潤滑油の温度を計測する温度センサ７０が潤滑油回収路６０上に設けられている。本実施例では、潤滑油回収装置６１の下流側に温度センサ７０が設けられている。温度センサ７０の計測情報は、管理装置１００と潤滑油貯蔵庫８０内に設けられた温度管理部８１に送信される。 The present embodiment has the following configuration in order to maintain the temperature of the lubricating oil supplied to the rolling bearing 30 via the bearing housing 40 at a predetermined temperature.
A temperature sensor 70 for measuring the temperature of the lubricating oil after cooling the rolling bearings in the bearing housing is provided on the lubricating oil recovery path 60. In this embodiment, a temperature sensor 70 is provided downstream of the lubricating oil recovery device 61. The measurement information of the temperature sensor 70 is transmitted to the management device 100 and a temperature management unit 81 provided in the lubricating oil storage 80.

温度管理部８１は、本実施例ではチラーが用いられている。チラーを構成する冷却部が潤滑油に浸漬されており、温度センサ７０の計測情報（軸受箱内の転がり軸受冷却後の潤滑油温度情報）を温度管理部８１に直接取り込み、計測情報に基づきチラーを構成する圧縮機の回転数をインバータ制御して、潤滑油の油温を例えば常温（２３度）±１度に温度管理するようにしている。温度センサ７０の計測情報は管理装置１００にも送信されており、管理装置１００から制御指令を温度管理部８１に送信し、管理装置１００からの制御指令に基づき温度管理部８１による潤滑油の冷却を制御するようにしても良い。例えば４つの軸受箱４０ａ〜４０ｄ（転がり軸受３０ａ〜３０ｄ）毎の潤滑油の温度の変化状況を監視して管理装置１００から制御指令により特定の軸受箱４０ａ〜４０ｄ（特定の転がり軸受３０ａ〜３０ｄ）に潤滑油を供給する潤滑油貯蔵庫８０の潤滑油の冷却を温度管理部８１による温度制御とは異ならせて制御することもできる。管理装置は入力部、ＣＰＵ、メモリ、出力部を備える。   As the temperature management unit 81, a chiller is used in the present embodiment. The cooling part constituting the chiller is immersed in the lubricating oil, and the measurement information of the temperature sensor 70 (the lubricating oil temperature information after the cooling of the rolling bearing in the bearing housing) is directly taken into the temperature management part 81, and the chiller is based on the measurement information. Is controlled by an inverter to control the lubricating oil temperature to, for example, normal temperature (23 degrees) ± 1 degree. The measurement information of the temperature sensor 70 is also transmitted to the management device 100, and a control command is transmitted from the management device 100 to the temperature management unit 81, and cooling of the lubricating oil by the temperature management unit 81 is performed based on the control command from the management device 100. May be controlled. For example, the temperature change state of the lubricating oil for each of the four bearing housings 40a to 40d (rolling bearings 30a to 30d) is monitored, and the specific bearing housings 40a to 40d (specific rolling bearings 30a to 30d) are controlled by the control command from the management device 100. The cooling of the lubricating oil in the lubricating oil storage 80 for supplying the lubricating oil can be controlled differently from the temperature control by the temperature management unit 81. The management device includes an input unit, a CPU, a memory, and an output unit.

本実施例では、転がり軸受３０に潤滑油を供給して発熱部である転がり軸受を直接冷却するようにしており、さらに、軸受箱内の転がり軸受冷却後の潤滑油温度情報に基づき温度管理部８１で制御することにより潤滑油貯蔵庫８０内の潤滑油の温度を所定の温度に維持するようにしている。すなわち、本実施例では、潤滑油の冷却を制御して潤滑油に冷却機能を積極的に持たせて発熱部である軸受部を直接冷却するようにしているので、ロールプレス装置の軸受部及び軸受箱の温度を効果的に管理することができる。また、本実施例では、転がり軸受で発生する熱を効果的に奪うことができ、軸受部及び軸受箱の蓄熱量を所定値以内に抑え、軸受部及び軸受箱の温度を所定の温度範囲内に保持・抑制することが可能となる。その結果として、軸受部及び軸受箱からロールへ伝導される熱量を減らし、ロールの熱変形を減らす。これにより、高精度な二次電池用電極材の圧縮加工が、ロールプレス機の高速回転、長時間運転の下でも可能になる。なお、本実施例では、潤滑油の油温を例えば常温（２３度）±１度に温度管理するようにしている。本実施例では、二次電池用電極材３を常温でプレス加工するようにしているので、潤滑油の温度を冷却しすぎると、ロールの熱変形に悪い影響を与える可能性がある。このようなことから、常温を基準として潤滑油の温度を管理するのが望ましい。   In the present embodiment, the lubricating oil is supplied to the rolling bearing 30 to directly cool the rolling bearing, which is a heat generating part. Further, the temperature management unit is controlled based on the lubricating oil temperature information after the cooling of the rolling bearing in the bearing housing. By controlling at 81, the temperature of the lubricating oil in the lubricating oil storage 80 is maintained at a predetermined temperature. That is, in the present embodiment, the cooling of the lubricating oil is controlled to positively provide the lubricating oil with a cooling function so as to directly cool the bearing portion, which is a heat generating portion. The temperature of the bearing housing can be managed effectively. Further, in this embodiment, the heat generated in the rolling bearing can be effectively removed, the heat storage amount of the bearing portion and the bearing box is suppressed to within a predetermined value, and the temperature of the bearing portion and the bearing box is kept within a predetermined temperature range. Can be held and suppressed. As a result, the amount of heat conducted from the bearing portion and the bearing housing to the roll is reduced, and the thermal deformation of the roll is reduced. Thus, highly accurate compression processing of the electrode material for the secondary battery can be performed even under high-speed rotation and long-time operation of the roll press machine. In this embodiment, the lubricating oil temperature is controlled, for example, to room temperature (23 degrees) ± 1 degree. In this embodiment, since the secondary battery electrode material 3 is pressed at room temperature, if the lubricating oil temperature is excessively cooled, it may adversely affect the thermal deformation of the roll. For this reason, it is desirable to control the temperature of the lubricating oil based on normal temperature.

図４に、本実施例による油循環潤滑方式による軸受冷却（軸受内部に一定流量の潤滑油を供給して軸受冷却）した場合と軸受冷却しない場合の軸受温度の変化について示す。縦軸は軸受温度、横軸は経過時間（ｔ０〜ｔ１）を示す。
図４に示すように、軸受冷却なしの場合には、軸受温度はＴ１→Ｔ２に大幅に温度上昇し、本実施例の軸受冷却ありの場合には、軸受温度Ｔ３→Ｔ４に若干の温度上昇となる。時刻ｔ０における温度Ｔ１≒Ｔ３とすると、軸受冷却をすることにより、ｔ０からｔ１の時間（Δｔ）において、温度ΔＴの温度抑制効果がある。 FIG. 4 shows a change in the bearing temperature when the bearing is cooled by the oil circulation lubrication system according to the present embodiment (the bearing is cooled by supplying a constant flow rate of lubricating oil inside the bearing) and when the bearing is not cooled. The vertical axis indicates the bearing temperature, and the horizontal axis indicates the elapsed time (t0 to t1).
As shown in FIG. 4, when the bearing is not cooled, the bearing temperature rises significantly from T1 to T2, and when the bearing is cooled in this embodiment, the bearing temperature rises slightly from T3 to T4. Becomes Assuming that the temperature T1 at time t0 is approximately equal to T3, the cooling of the bearing has an effect of suppressing the temperature ΔT during the time (Δt) from t0 to t1.

次に図２を用いて本発明の実施例を説明する。図２は、本発明の実施例の軸受冷却機構を備えたロールプレス装置の全体構成を示す図である。本実施例では、各軸受部に潤滑油を供給する潤滑油貯蔵庫８０が１つのケースを示す。   Next, an embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram showing the overall configuration of a roll press device provided with a bearing cooling mechanism according to an embodiment of the present invention. In this embodiment, a single lubricating oil storage 80 for supplying lubricating oil to each bearing unit is shown.

一つの潤滑油貯蔵庫８０から潤滑油供給路５０ａ〜５０ｄを介して軸受箱４０ａ〜４０ｄ内の転がり軸受３０ａ〜３０ｄに供給される。潤滑油供給路５０ａ〜５０ｄ上には、それぞれ潤滑油供給装置５１ａ〜５１ｄが設けられ、所定量の潤滑油を継続して転がり軸受３０ａ〜３０ｄのそれぞれに供給する。転がり軸受３０ａ〜３０ｄを潤滑かつ冷却した後の潤滑油は潤滑油回収路６０ａ〜６０ｄを介して潤滑油貯蔵庫８０に回収される。潤滑油回収路６０ａ〜６０ｄ上には、それぞれ潤滑油回収装置６１ａ〜６１ｄが設けられている。   The lubricant is supplied from one lubricating oil storage 80 to the rolling bearings 30a to 30d in the bearing boxes 40a to 40d via the lubricating oil supply paths 50a to 50d. Lubricating oil supply devices 51a to 51d are provided on the lubricating oil supply passages 50a to 50d, respectively, and continuously supply a predetermined amount of lubricating oil to each of the rolling bearings 30a to 30d. The lubricating oil after lubricating and cooling the rolling bearings 30a to 30d is collected in the lubricating oil storage 80 via the lubricating oil collecting passages 60a to 60d. Lubricating oil collecting devices 61a to 61d are provided on the lubricating oil collecting passages 60a to 60d, respectively.

軸受箱内の転がり軸受冷却後の潤滑油の温度を計測する温度センサ７０ａ〜７０ｄが潤滑油回収路６０ａ〜６０ｄ上に設けられている。本実施例では、潤滑油回収装置６１ａ〜６１ｄの下流側に温度センサ７０ａ〜７０ｄが設けられている。温度センサ７０ａ〜７０ｄの計測情報は、管理装置１００と潤滑油貯蔵庫８０内に設けられた温度管理部８１に送信される。温度管理部８１は、温度センサ７０ａ〜７０ｄの計測情報を直接取り込み、計測情報の平均値に基づきチラーを構成する圧縮機の回転数をインバータ制御して、潤滑油の油温を例えば常温（２３度）±１度に温度管理するようにしている。温度センサ７０ａ〜７０ｄの計測情報は管理装置１００にも送信されており、管理装置１００から制御指令を温度管理部８１に送信し、管理装置１００からの制御指令に基づき温度管理部８１による潤滑油の冷却を制御するようにしても良い。本実施例では比較的大きな潤滑油貯蔵庫８０を準備することができる場合に適する。   Temperature sensors 70a to 70d for measuring the temperature of the lubricating oil after the rolling bearing in the bearing housing is cooled are provided on the lubricating oil recovery paths 60a to 60d. In the present embodiment, temperature sensors 70a to 70d are provided downstream of the lubricating oil recovery devices 61a to 61d. The measurement information of the temperature sensors 70 a to 70 d is transmitted to the management device 100 and the temperature management unit 81 provided in the lubricating oil storage 80. The temperature management unit 81 directly takes in the measurement information of the temperature sensors 70a to 70d, controls the number of revolutions of the compressor constituting the chiller based on the average value of the measurement information by inverter, and sets the oil temperature of the lubricating oil to, for example, normal temperature (23 (Degree) The temperature is controlled to ± 1 degree. The measurement information of the temperature sensors 70 a to 70 d is also transmitted to the management device 100, and a control command is transmitted from the management device 100 to the temperature management unit 81, and the lubricating oil is controlled by the temperature management unit 81 based on the control command from the management device 100. May be controlled. This embodiment is suitable when a relatively large lubricating oil storage 80 can be prepared.

本実施例では、図１に示す実施例と同様に、既存の潤滑油に軸受部を冷却する冷却媒体としての機能を持たせ、それぞれの軸受部（転がり軸受３０ａ〜３０ｄ）にそれぞれ温度管理された潤滑油を冷却専用の供給路を設けることなく同一の潤滑油供給路５０ａ〜５０ｄを介して供給し、また、冷却専用の回収路を設けることなく同一の潤滑油回収路６０ａ〜６０ｄを介して回収することにより、全ての軸受部及び軸受箱の蓄熱量を所定範囲内に保持することができ、軸受部及び軸受箱の温度を所定温度に保持することができる。これにより、高精度な二次電池用電極材の圧縮加工が、ロールプレス機の高速回転、長時間運転の下でも可能になる。   In this embodiment, as in the embodiment shown in FIG. 1, the existing lubricating oil is provided with a function as a cooling medium for cooling the bearings, and the temperature of each bearing (rolling bearings 30a to 30d) is controlled. The lubricating oil is supplied via the same lubricating oil supply passages 50a to 50d without providing a cooling-dedicated supply passage, and is supplied via the same lubricating oil collection passages 60a to 60d without providing a cooling-dedicated recovery passage. By collecting the bearings, the heat storage amounts of all the bearing portions and the bearing boxes can be kept within a predetermined range, and the temperatures of the bearing portions and the bearing boxes can be kept at a predetermined temperature. This enables highly accurate compression processing of the electrode material for a secondary battery even under high-speed rotation and long-time operation of a roll press.

なお、本実施例では、一つの潤滑油貯蔵庫８０を４つの転がり軸受３０ａ〜３０ｄの冷却に用いるようにしているが、例えば、二つの潤滑油貯蔵庫を設け、それぞれの潤滑油貯蔵庫を二つの転がり軸受の冷却に用いるようにしても良い。例えば、上ロール１０側の左右の転がり軸受３０ａと３０ｃ、下ロール１１側の左右の転がり軸受３０ｂと３０ｄの組み合わせで一つの潤滑油貯蔵庫を用いるようにしたり、右側の上下の転がり軸受３０ａと３０ｂ、左側の上下の転がり軸受３０ｃと３０ｄの組み合わせで一つの潤滑油貯蔵庫を用いるようにしたりしても良い。   In this embodiment, one lubricating oil storage 80 is used for cooling the four rolling bearings 30a to 30d. However, for example, two lubricating oil storages are provided, and each lubricating oil storage is used for two rolling. It may be used for cooling the bearing. For example, one lubricating oil storage may be used in combination of the left and right rolling bearings 30a and 30c on the upper roll 10 side and the left and right rolling bearings 30b and 30d on the lower roll 11 side, or the upper and lower right and left rolling bearings 30a and 30b may be used. Alternatively, one lubricating oil storage may be used in combination with the upper and lower left and right rolling bearings 30c and 30d.

次に図３を用いて本発明の実施例を説明する。図３は、本発明の実施例の軸受冷却機構を備えたロールプレス装置の全体構成を示す図である。本実施例では、軸受ごとに潤滑油貯蔵庫があるケースを示す。すなわち、転がり軸受３０ａ〜３０ｄ毎に潤滑油貯蔵庫８０ａ〜８０ｄが設けられ、それぞれの潤滑油貯蔵庫８０ａ〜８０ｄに温度管理部８１ａ〜８１ｄが設けられている。これらの点以外は、図２と同様である。   Next, an embodiment of the present invention will be described with reference to FIG. FIG. 3 is a diagram showing the overall configuration of a roll press device provided with a bearing cooling mechanism according to an embodiment of the present invention. In this embodiment, a case is shown in which a lubricating oil storage is provided for each bearing. That is, lubricating oil storages 80a to 80d are provided for each of the rolling bearings 30a to 30d, and temperature management units 81a to 81d are provided in the respective lubricating oil storages 80a to 80d. Except for these points, it is the same as FIG.

本実施例では、潤滑油貯蔵庫８０ａ〜８０ｄ内の潤滑油の温度管理が図２の実施例と比べて容易となる。また、潤滑油貯蔵庫８０ａ〜８０ｄの潤滑油収容量を小さくすることができ、低コスト化することが可能である。潤滑油貯蔵庫８０ａ〜８０ｄの潤滑油の収容量は例えば２０リットル程度である。   In the present embodiment, the temperature control of the lubricating oil in the lubricating oil storages 80a to 80d is easier than in the embodiment of FIG. Further, the amount of the lubricating oil stored in the lubricating oil storages 80a to 80d can be reduced, and the cost can be reduced. The storage amount of the lubricating oil in the lubricating oil storages 80a to 80d is, for example, about 20 liters.

なお、本発明は上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加えることも可能である。また、各実施例の構成の一部について、他の構成の追加，削除，置換をすることが可能である。   Note that the present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described above. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of one embodiment can be added to the configuration of another embodiment. Further, for a part of the configuration of each embodiment, it is possible to add, delete, or replace another configuration.

例えば、上述の実施例では、軸受箱内の転がり軸受冷却後の潤滑油の温度を計測して計測情報に基づき温度管理部を制御しているが、軸受箱に温度センサを設置してその計測情報に基づき温度管理部を制御するようにしても良い。但し、この場合、軸受箱が発熱部による熱を蓄熱した状態の情報であるため、軸受箱の計測温度と軸受部及び軸受箱の温度を所定の温度に維持するのに必要な潤滑油の温度との関係を予め求めておき、軸受箱の計測温度に基づき温度管理部での目標温度を設定する。この場合、管理装置１００による温度管理部の制御となる。   For example, in the above-described embodiment, the temperature of the lubricating oil after cooling the rolling bearing in the bearing housing is measured and the temperature management unit is controlled based on the measurement information. The temperature management unit may be controlled based on the information. However, in this case, since the information is a state in which the bearing housing stores heat generated by the heat generating portion, the temperature of the lubricating oil required to maintain the measured temperature of the bearing housing and the temperature of the bearing housing and the bearing housing at a predetermined temperature. Is determined in advance, and a target temperature in the temperature management unit is set based on the measured temperature of the bearing housing. In this case, the management device 100 controls the temperature management unit.
