Description

定溫水供給裝置Constant temperature water supply device

發明領域 本發明是有關於一種將來自水供給源的水調整成定溫並供給到加工裝置的定溫水供給裝置。Field of the Invention The present invention relates to a constant temperature water supply device that adjusts water from a water supply source to a constant temperature and supplies it to a processing device.

發明背景 一般在研磨裝置或切削裝置等的加工裝置中，會將加工水或主軸的冷卻水等的水溫管理在一定的溫度。藉由一定溫度的加工水或冷卻水之供給，來防止像是因機械零件的熱膨脹及熱收縮所造成的加工精度的惡化、或主軸的擦傷等因零件彼此的接觸而損傷裝置本體之情形。以往，已知有將供給至加工裝置的水保持於一定溫度的定溫水供給裝置(參照例如專利文獻1)。定溫水供給裝置是在從貯留槽至到達加工裝置的流路的中途設置溫度調整器，並將已藉由溫度調整器調整成一定溫度的水供給到加工裝置。 先前技術文獻 專利文獻BACKGROUND OF THE INVENTION Generally, in a processing device such as a grinding device or a cutting device, the temperature of the processing water or the cooling water of the spindle is controlled to a certain temperature. The supply of processing water or cooling water at a certain temperature prevents the deterioration of the machining accuracy caused by thermal expansion and contraction of mechanical parts, or the abrasion of the spindle, etc., which damages the device body due to the contact between the parts. Conventionally, a constant temperature water supply device that keeps water supplied to a processing device at a constant temperature is known (see, for example, Patent Document 1).

發明概要 發明欲解決之課題 然而，由於主軸等的驅動部的冷卻水並不需要像供給到工件等的加工水那種程度的純度或溫度調整，所以有時會使其在加工裝置與定溫水供給裝置之間循環而使用。在這種情況下，若在不更換加工水的情形下經過長時間而持續使用冷卻水的話，不純物會被濃縮而作為污垢堆積於配管等中，而將此污垢與冷卻水一起供給至驅動部，因此恐有導致驅動部之損壞的疑慮。又，因為於驅動部的冷卻水的更換時，必須停止加工裝置的運轉，因而有產生停機時間的問題。SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION However, since the cooling water of the driving section such as the spindle does not require the degree of purity or temperature adjustment as the processing water supplied to the workpiece or the like, it may sometimes be used in the processing device and the constant temperature It is used by circulating between water supply devices. In this case, if the cooling water is continuously used for a long period of time without changing the processing water, the impurities will be concentrated and accumulate as dirt in the piping, etc., and this dirt will be supplied to the drive unit together with the cooling water Therefore, there is a possibility that the driver may be damaged. In addition, since it is necessary to stop the operation of the processing device when replacing the cooling water of the drive unit, there is a problem of downtime.

本發明是有鑑於所述問題點而作成之發明，其目的在於提供一種能夠防止驅動部之損壞，並且大幅縮減冷卻水的更換作業及停機時間的定溫水供給裝置。 用以解決課題之手段The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a constant-temperature water supply device capable of preventing damage to a driving unit and greatly reducing cooling water replacement work and downtime. Means to solve the problem

本發明之定溫水供給裝置，為將來自水供給源的水調整成定溫並供給至加工裝置，該定溫水供給裝置的特徵在於具備： 第1貯留槽，貯留從水供給源所供給的加工用的水； 第1送出幫浦，將水從該第1貯留槽往加工裝置送出； 水溫調整機構，配設於從該第1貯留槽至到達該加工裝置的第1流路上的比該第1送出幫浦更下游處，並將水的溫度調整成預定溫度； 第2貯留槽，貯留該加工裝置的驅動部冷卻用的水； 第2送出幫浦，將水從該第2貯留槽往該加工裝置送出； 循環流路，使該加工裝置內的驅動部冷卻後的水往該第2貯留槽返回而使其循環； 定溫水供給流路，在該第1流路上的該水溫調整機構的下游處從該第1流路分歧並連通到第2貯留槽而形成，以將已調整成該預定溫度的水供給到該第2貯留槽； 第1電磁閥，配設於從該第1流路往該定溫水供給流路的分歧部位； 排水流路，在從該第2貯留槽至到達該加工裝置的第2流路上的比該第2送出幫浦更下游處從第2流路分歧而形成，以將該第2貯留槽的水往外部排出； 第2電磁閥，配設於從該第2流路往該排水流路的分歧部位；及 控制機構，至少控制該第1電磁閥及該第2電磁閥的開關， 該控制機構具備管理從該第2貯留槽排水的時序之時序管理部、與控制該第1電磁閥及該第2電磁閥的開關之電磁閥控制部， 並以預定的時序，將該第2電磁閥設為開啟而將預定量的該第2貯留槽內的水排出，並且將該第1電磁閥設為開啟而將預定量的該第1流路內的該水供給到該第2貯留槽，以免使侵入到進行循環的驅動部冷卻水內的不純物濃度上升。The constant temperature water supply device of the present invention adjusts the water from the water supply source to a constant temperature and supplies it to the processing device. The constant temperature water supply device is characterized by comprising: a first storage tank storing the supply from the water supply source Water for processing; the first pump is sent to send water from the first storage tank to the processing device; the water temperature adjustment mechanism is arranged on the first flow path from the first storage tank to the processing device Downstream of the first pump, the temperature of the water is adjusted to a predetermined temperature; the second storage tank stores the water used for cooling the driving unit of the processing device; the second pump sends the water from the second The storage tank is sent to the processing device; the circulation flow path returns the water cooled by the driving part in the processing device to the second storage tank and circulates it; the constant temperature water supply flow path on the first flow path The downstream of the water temperature adjustment mechanism branches from the first flow path and communicates with the second storage tank to form water that has been adjusted to the predetermined temperature to the second storage tank; the first solenoid valve is provided At the branching point from the first flow path to the constant temperature water supply flow path; the drain flow path is further downstream than the second delivery pump on the second flow path from the second storage tank to the processing device The branch is formed by diverging from the second flow path to discharge the water of the second storage tank to the outside; the second solenoid valve is arranged at a diverging portion from the second flow path to the drainage flow path; and the control mechanism, A switch that controls at least the first solenoid valve and the second solenoid valve, the control mechanism includes a timing management unit that manages the timing of draining water from the second storage tank, and a switch that controls the first solenoid valve and the second solenoid valve Solenoid valve control unit, and at a predetermined timing, the second solenoid valve is turned on to discharge a predetermined amount of water in the second storage tank, and the first solenoid valve is turned on to set a predetermined amount The water in the first flow path is supplied to the second storage tank so as not to increase the concentration of impurities entering the cooling water of the circulating drive unit.

根據此構成，可將第1貯留槽內的加工用的水在第1流路的中途藉由水溫調整機構調整成預定溫度，且將溫度調整後的加工用的水的一部分通過定溫水供給流路供給到第2貯留槽。另一方面，將第2貯留槽內的驅動部冷卻用的水通過第2流路供給至加工裝置的驅動部，且通過循環流路返回到第2貯留槽，並且將驅動部冷卻用的水的一部分通過排水流路而排出。亦即，由於一方面可將第2貯留槽內的驅動部冷卻用的水排出，另一方面可從第1貯留槽將加工用的水供給至第2貯留槽，所以可自動地替換第2貯留槽內的水。由於一邊替換水一邊在第2貯留槽與加工裝置的驅動部之間循環驅動部冷卻用的水，所以不會有不純物濃度上升之情形，且不會有因不純物堆積而成的污垢之供給而導致驅動部損壞的情形。又，由於可在將裝置持續地運轉的狀態下，自動地替換第2貯留槽內的水，所以變得不需要進行驅動部冷卻用的水的更換作業，並且可以大幅地減少停機時間。此外，由於對第2貯留槽會供給與排水量大致同量之溫度調整後的加工用的水，所以可以使驅動部冷卻用的水的溫度變動較小，進而防止因溫度變動所形成的機械故障。又，由於可以藉由單一的水溫調整機構來調整2個系統的水，所以可以減少零件數量而縮減成本。According to this configuration, the processing water in the first storage tank can be adjusted to a predetermined temperature by the water temperature adjustment mechanism in the middle of the first flow path, and part of the temperature-adjusted processing water can pass through the constant temperature water The supply flow path is supplied to the second storage tank. On the other hand, the water for cooling the driving part in the second storage tank is supplied to the driving part of the processing device through the second flow path, and returns to the second storage tank through the circulation flow path, and the water for cooling the driving part Part of it is discharged through the drainage channel. That is, on the one hand, the water for cooling the driving part in the second storage tank can be discharged, and on the other hand, the processing water can be supplied from the first storage tank to the second storage tank, so the second tank can be automatically replaced Water in the holding tank. Since the water for cooling the drive unit is circulated between the second storage tank and the drive unit of the processing device while replacing the water, there is no possibility that the concentration of impurities will increase, and there will be no supply of dirt due to the accumulation of impurities Causes damage to the drive unit. In addition, since the water in the second storage tank can be automatically replaced while the device is continuously operated, it is not necessary to replace the water for cooling the drive unit, and the downtime can be greatly reduced. In addition, since the second storage tank is supplied with processing water whose temperature is adjusted to the same amount as the drainage amount, it is possible to make the temperature variation of the cooling water of the driving unit small, and to prevent mechanical failure due to the temperature variation . In addition, since the water of the two systems can be adjusted by a single water temperature adjustment mechanism, the number of parts can be reduced and the cost can be reduced.

又，在本發明的定溫水供給裝置中具備冷卻機構，該冷卻機構是配設在比從該第2貯留槽至到達該加工裝置的第2流路上的該第2送出幫浦更下游處，以將水冷卻到預定溫度。 發明效果In addition, the constant temperature water supply device of the present invention includes a cooling mechanism disposed downstream of the second delivery pump from the second storage tank to the second flow path to the processing device To cool the water to a predetermined temperature. Invention effect

根據本發明，由於一方面可將第2貯留槽內的驅動部冷卻用的水排出，另一方面可從第1貯留槽將加工用的定溫水供給至第2貯留槽，所以可自動地替換第2貯留槽內的水。據此，可以防止驅動部的損壞，並且大幅地縮減冷卻水的更換作業及停機時間。According to the present invention, on the one hand, the water for cooling the driving part in the second storage tank can be discharged, and on the other hand, the constant temperature water for processing can be supplied from the first storage tank to the second storage tank, so it can be automatically Replace the water in the second storage tank. According to this, it is possible to prevent damage to the drive unit, and to greatly reduce the cooling water replacement work and downtime.

用以實施發明之形態 以下，參照附加圖式，說明本實施形態的定溫水供給裝置。圖1是本實施形態之定溫水供給裝置的示意圖。再者，在以下的說明中，雖然例示的是於切削裝置或磨削裝置等的加工裝置中設置定溫水供給裝置的構成，但並不限定為此構成。定溫水供給裝置也可以設置於具備有主軸等的驅動部的其他的加工裝置上。Forms for Carrying Out the Invention The fixed temperature water supply device of this embodiment will be described below with reference to the attached drawings. FIG. 1 is a schematic diagram of a constant temperature water supply device of this embodiment. In the following description, although a configuration in which a constant temperature water supply device is provided in a processing device such as a cutting device or a grinding device is exemplified, it is not limited to this configuration. The constant-temperature water supply device may be installed on another processing device including a drive unit such as a spindle.

如圖1所示，定溫水供給裝置1是將來自水供給源2的水調整成定溫並供給到加工裝置3的裝置，並且具備有供給加工用的水的第1系統10、與供給驅動部冷卻用的水的第2系統20。第1系統10是將加工用的水供給到加工裝置3的噴嘴(未圖示)等以將加工部位冷卻及洗淨。供給後的加工用的水是透過加工裝置3的水箱(未圖示)等而被排出。由於加工用的水也會噴附到加工對象的工件等之上，所以會調整成一定溫度以免對加工精度造成影響。As shown in FIG. 1, the constant-temperature water supply device 1 is a device that adjusts water from the water supply source 2 to a constant temperature and supplies it to the processing device 3, and is provided with a first system 10 that supplies water for processing and a supply The second system 20 of the cooling water for the drive unit. The first system 10 is to supply water for processing to a nozzle (not shown) or the like of the processing device 3 to cool and wash the processing site. The supplied processing water is discharged through a water tank (not shown) of the processing device 3 or the like. Since the water used for processing is also sprayed on the workpiece to be processed, it will be adjusted to a certain temperature to avoid affecting the processing accuracy.

在第2系統20中，是將驅動部冷卻用的水供給到主軸、工作夾台或旋轉工作台的軸馬達等的驅動部4內，以將在這些驅動部4產生的熱冷卻。由於驅動部冷卻用的水僅需冷卻驅動部4即可，所以不需要像加工用水一般的純度或溫度調整，而可在定溫水供給裝置1與加工裝置3之間循環。像這樣，於加工裝置3的運轉時，是使來自水供給源2的水持續通過第1系統10以供給到加工裝置3，並且在第2系統20使水循環以持續冷卻在驅動部4產生的熱。In the second system 20, water for cooling the drive unit is supplied into the drive unit 4 such as a spindle, a work clamp table, or a shaft motor of a rotary table to cool the heat generated in these drive units 4. Since the water for cooling the drive unit only needs to cool the drive unit 4, there is no need for purity or temperature adjustment like processing water, but it can be circulated between the constant temperature water supply device 1 and the processing device 3. In this way, during the operation of the processing device 3, the water from the water supply source 2 is continuously passed through the first system 10 to be supplied to the processing device 3, and the water is circulated in the second system 20 to continuously cool the generated in the driving unit 4. heat.

然而，一般而言若將驅動部冷卻用的水經過長時間持續循環並使用時，恐有使不純物被濃縮而作為污垢堆積於流路等之疑慮。於是，在本實施形態的定溫水供給裝置1中，是做成：將於第2系統20進行循環的驅動部冷卻用的水的一部分排出，並且將第1系統10的加工用的水的一部分供給到第2系統20，以自動地替換第2系統20內的水。藉此，由於可以抑制不純物的濃縮，進而在使加工裝置3運轉的狀態下替換第2系統20內的水，所以變得可大幅地減少停機時間。However, in general, if the water for cooling the drive unit is continuously circulated and used for a long period of time, there is a possibility that impurities may be concentrated and accumulate as dirt on the flow path. Therefore, in the fixed-temperature water supply device 1 of the present embodiment, a part of the water for cooling the driving part that circulates the second system 20 is discharged, and the water for processing of the first system 10 is discharged A part is supplied to the second system 20 to automatically replace the water in the second system 20. Thereby, since it is possible to suppress the concentration of impurities and further replace the water in the second system 20 with the processing device 3 in operation, it is possible to significantly reduce downtime.

又，若在加工裝置3的初期運轉時，驅動部冷卻用的水過冷時，會有導致各驅動部4的軸承等收縮而使旋轉軸擦傷的可能性。通常來說，雖然可藉加工前驅動部4的空載(idling)時的發熱來使驅動部冷卻用的水上升到一定溫度而抑制加工中的擦傷，但會使初期運轉時的啟動時間變得較遲。於是，在本實施形態中是做成將已在第1系統10進行溫度調整成預定溫度的加工用的水供給到第2系統20。藉此，不會有第2系統20內的驅動部冷卻用的水變得過冷之情形，而可將初期運轉時的啟動時間提前。In addition, if the water for cooling the drive unit is too cold during the initial operation of the processing device 3, the bearings of each drive unit 4 may shrink and the rotating shaft may be scratched. In general, although the heat generated during idling of the drive unit 4 before processing can be used to raise the cooling water for the drive unit to a certain temperature to suppress scratches during processing, the start-up time during initial operation may be changed It's late. Therefore, in the present embodiment, the water for processing whose temperature has been adjusted in the first system 10 to a predetermined temperature is supplied to the second system 20. Thereby, the water for cooling the drive unit in the second system 20 does not become too cold, and the start-up time during the initial operation can be advanced.

以下，針對本實施形態的定溫水供給裝置1之第1系統10及第2系統20之詳細構成進行說明。在第1系統10中，設置有從第1貯留槽11至到達加工裝置3的第1流路12。在第1流路12上，從上游朝向下游依序設置有第1貯留槽11、第1送出幫浦14、第1壓力檢測機構15、水溫調整機構16及第1過濾器17。在第1貯留槽11貯留有從水供給源2所供給的加工用的水，且第1貯留槽11內的水是藉由第1送出幫浦14而從第1貯留槽11送出至加工裝置3。Hereinafter, the detailed configuration of the first system 10 and the second system 20 of the constant temperature water supply device 1 of the present embodiment will be described. The first system 10 is provided with a first flow path 12 from the first storage tank 11 to the processing device 3. The first flow path 12 is provided with a first storage tank 11, a first delivery pump 14, a first pressure detection mechanism 15, a water temperature adjustment mechanism 16, and a first filter 17 in order from upstream to downstream. The processing water supplied from the water supply source 2 is stored in the first storage tank 11, and the water in the first storage tank 11 is sent from the first storage tank 11 to the processing device by the first sending pump 14 3.

第1送出幫浦14的送出壓力是藉由第1壓力檢測機構15而被檢測，並且可因應第1壓力檢測機構15的檢測結果來調整第1送出幫浦14的送出壓力。在第1流路12上的第1送出幫浦14的下游，是藉由水溫調整機構16來將水的溫度調整成預定溫度。水溫調整機構16是由冷卻器(chiller)等的第1冷卻機構18與加熱器等加熱機構19所構成，並且組合第1冷卻機構18的冷卻與加熱機構19的加熱來將水調整到預定溫度。已成為預定溫度的水(定溫水)會通過第1過濾器17，並作為加工用的水而供給到加工裝置3內的噴嘴。The delivery pressure of the first delivery pump 14 is detected by the first pressure detection mechanism 15, and the delivery pressure of the first delivery pump 14 can be adjusted according to the detection result of the first pressure detection mechanism 15. Downstream of the first delivery pump 14 on the first flow path 12, the water temperature adjustment mechanism 16 adjusts the temperature of the water to a predetermined temperature. The water temperature adjustment mechanism 16 is composed of a first cooling mechanism 18 such as a chiller and a heating mechanism 19 such as a heater, and combines the cooling of the first cooling mechanism 18 and the heating of the heating mechanism 19 to adjust the water to a predetermined level temperature. Water having reached a predetermined temperature (constant temperature water) passes through the first filter 17 and is supplied to the nozzle in the processing device 3 as water for processing.

在第2系統20中，設置有從第2貯留槽21至到達加工裝置3之驅動部4的第2流路22、與從加工裝置3之驅動部4至到達第2貯留槽21的循環流路23。在第2流路22上，從上游朝向下游而設置有第2貯留槽21、第2送出幫浦24、第2壓力檢測機構25、第2冷卻機構(冷卻機構)26及第2過濾器27。在第2貯留槽21中貯留有加工裝置3的驅動部冷卻用的水，且第2貯留槽21內的水是藉由第2送出幫浦24，而從第2貯留槽21送出至加工裝置3的驅動部4。The second system 20 is provided with a second flow path 22 from the second storage tank 21 to the driving unit 4 of the processing device 3 and a circulating flow from the driving unit 4 of the processing device 3 to the second storage tank 21路23. The second flow path 22 is provided with a second storage tank 21, a second delivery pump 24, a second pressure detection mechanism 25, a second cooling mechanism (cooling mechanism) 26, and a second filter 27 from upstream to downstream . In the second storage tank 21, water for cooling the driving portion of the processing device 3 is stored, and the water in the second storage tank 21 is sent from the second storage tank 21 to the processing device by the second sending pump 24 3的驱动部4。 3 drive section 4.

第2送出幫浦24的送出壓力是藉由第2壓力檢測機構25而被檢測，並且可因應第2壓力檢測機構25的檢測結果來調整第2送出幫浦24的送出壓力。在第2流路22上的第2送出幫浦24的下游，是藉由冷卻器等的第2冷卻機構26來將水的溫度冷卻到預定溫度。已被冷卻到預定溫度的水會通過第2過濾器27，並作為驅動部冷卻用的水而供給到加工裝置3內的驅動部4。又，驅動部冷卻後的水會通過循環流路23返回到第2貯留槽21內，並在第2貯留槽21與驅動部4之間循環。The delivery pressure of the second delivery pump 24 is detected by the second pressure detection mechanism 25, and the delivery pressure of the second delivery pump 24 can be adjusted according to the detection result of the second pressure detection mechanism 25. Downstream of the second delivery pump 24 on the second flow path 22, the temperature of the water is cooled to a predetermined temperature by a second cooling mechanism 26 such as a cooler. The water cooled to a predetermined temperature passes through the second filter 27 and is supplied to the driving unit 4 in the processing device 3 as cooling water for the driving unit. In addition, the water cooled by the drive unit returns to the second storage tank 21 through the circulation channel 23 and circulates between the second storage tank 21 and the drive unit 4.

又，在第1系統10中，是在水溫調整機構16的下游設置從第1流路12分歧並連通到第2貯留槽21的定溫水供給流路31，並將已調整成預定溫度的水通過定溫水供給流路31來從第1流路12供給到第2貯留槽21。在第2系統20中，是在第2送出幫浦24的下游設置有從第2流路22分歧並將第2貯留槽21的水往外部排出的排水流路32。在從第1流路12往定溫水供給流路31的分歧部位上，配設有往第2貯留槽21之供水用的第1電磁閥33，而在從第2流路22往排水流路32的分歧部位上，配設有第2貯留槽21之排水用的第2電磁閥34。Furthermore, in the first system 10, a fixed-temperature water supply flow path 31 branching from the first flow path 12 and communicating with the second storage tank 21 is provided downstream of the water temperature adjustment mechanism 16, and adjusted to a predetermined temperature The water is supplied from the first flow path 12 to the second storage tank 21 through the constant temperature water supply flow path 31. In the second system 20, a drain channel 32 branching from the second channel 22 and discharging the water in the second storage tank 21 to the outside is provided downstream of the second delivery pump 24. A first solenoid valve 33 for water supply to the second storage tank 21 is provided at a branching portion from the first flow path 12 to the constant-temperature water supply flow path 31, and a drain flow is discharged from the second flow path 22 A second solenoid valve 34 for draining the second storage tank 21 is arranged at a branched portion of the path 32.

在定溫水供給裝置1中，設置有至少控制第1電磁閥33及第2電磁閥34的開關的控制機構41。在控制機構41中，設置有管理來自第2貯留槽21的排水時序的時序管理部42、與控制第1電磁閥33及第2電磁閥34的開關的電磁閥控制部43。再者，控制機構41是由執行各種處理的處理器(processor)或記憶體(memory)等所構成。記憶體是因應用途而由ROM(唯讀記憶體(Read Only Memory))、RAM(隨機存取記憶體(Random Access Memory))等的一個或複數個儲存媒體所構成。在記憶體中儲存有用於執行時序管理或開關控制的程式等。The constant temperature water supply device 1 is provided with a control mechanism 41 that controls at least the opening and closing of the first solenoid valve 33 and the second solenoid valve 34. The control mechanism 41 is provided with a timing management unit 42 that manages the timing of draining from the second storage tank 21, and a solenoid valve control unit 43 that controls the opening and closing of the first solenoid valve 33 and the second solenoid valve 34. In addition, the control mechanism 41 is constituted by a processor or memory that executes various processes. The memory is composed of one or more storage media such as ROM (Read Only Memory), RAM (Random Access Memory), etc. according to the application. Programs for performing timing management or switch control are stored in the memory.

在如此所構成的定溫水供給裝置1中，是在預定的時序下，開啟第2電磁閥34來將相當於預定量的第2貯留槽21內的水排出，並且開啟第1電磁閥33來將相當於預定量的第1流路12內的水供給至第2貯留槽21。一邊將第2貯留槽21內的水按預定量進行替換，一邊使水在第2貯留槽21與加工裝置3的驅動部4之間循環。據此，可以抑制在第2貯留槽21與驅動部4之間進行循環的水的不純物濃度之上升，並且可自動地實施第2貯留槽21內的驅動部冷卻用的水的更換作業。In the constant temperature water supply device 1 configured as described above, the second solenoid valve 34 is opened at a predetermined timing to discharge the water in the second storage tank 21 corresponding to a predetermined amount, and the first solenoid valve 33 is opened Then, the water in the first flow path 12 corresponding to a predetermined amount is supplied to the second storage tank 21. While replacing the water in the second storage tank 21 by a predetermined amount, the water is circulated between the second storage tank 21 and the drive unit 4 of the processing device 3. According to this, it is possible to suppress an increase in the concentration of impurities in the water circulating between the second storage tank 21 and the drive unit 4, and it is possible to automatically perform the replacement operation of the water for cooling the drive unit in the second storage tank 21.

參照圖2，針對定溫水供給裝置所進行的水的供給動作進行說明。圖2是本實施形態之定溫水供給裝置所進行的水的供給動作之說明圖。再者，分別顯示的是圖2A為已停止從第1流路往第2貯留槽21的供水之供水停止狀態，圖2B為從第1流路對第2貯留槽21供水的供水狀態。2, the water supply operation by the constant temperature water supply device will be described. 2 is an explanatory diagram of the water supply operation performed by the constant temperature water supply device of the present embodiment. In addition, FIG. 2A shows the water supply stop state in which the water supply from the first flow path to the second storage tank 21 has been stopped, and FIG. 2B shows the water supply state in which the water supply from the first flow path to the second storage tank 21 is stopped.

如圖2A所示，在往第2貯留槽21的供水停止狀態下，是因應來自時序管理部42的指示，藉由電磁閥控制部43將定溫水供給流路31的第1電磁閥33及排水流路32的第2電磁閥34關閉。藉此，將從第1流路12往第2貯留槽21的供水停止，並且將第2貯留槽21往外部的排水停止。在這個往第2貯留槽21的供水停止狀態下，會從水供給源2對第1貯留槽11供給加工用的水，並將第1貯留槽11內的水藉由第1送出幫浦14的送出壓力送出到第1流路12內。As shown in FIG. 2A, in a state where water supply to the second storage tank 21 is stopped, in response to an instruction from the timing management unit 42, the solenoid valve control unit 43 supplies constant temperature water to the first solenoid valve 33 of the flow path 31 And the second solenoid valve 34 of the drain channel 32 is closed. As a result, the water supply from the first flow path 12 to the second storage tank 21 is stopped, and the drainage of the second storage tank 21 to the outside is stopped. When the water supply to the second storage tank 21 is stopped, the processing water is supplied from the water supply source 2 to the first storage tank 11, and the water in the first storage tank 11 is sent out of the pump 14 through the first The sending pressure is sent into the first flow path 12.

第1流路12內的水是藉由通過水溫調整機構16而被調整成預定溫度。在第1流路12內的水溫為預定溫度以上的情況下，可藉由水溫調整機構16的第1冷卻機構18來冷卻到預定溫度。又，在第1流路12內的水溫比預定溫度更低的情況下，可藉由水溫調整機構16的加熱機構19來加熱到預定溫度。並且，預定溫度的水會在已藉由第1過濾器17移除異物的狀態下，從加工裝置3的噴嘴朝向工件的加工點噴射。此加工用的水是透過加工裝置3的水箱等而排出到外部。The water in the first flow path 12 is adjusted to a predetermined temperature by passing through the water temperature adjustment mechanism 16. When the temperature of the water in the first flow path 12 is equal to or higher than the predetermined temperature, the first cooling mechanism 18 of the water temperature adjustment mechanism 16 can be used to cool to the predetermined temperature. In addition, when the temperature of the water in the first flow path 12 is lower than the predetermined temperature, it can be heated to the predetermined temperature by the heating mechanism 19 of the water temperature adjustment mechanism 16. In addition, water with a predetermined temperature is sprayed from the nozzle of the processing device 3 toward the processing point of the workpiece in a state where the foreign material has been removed by the first filter 17. The processing water is discharged to the outside through the water tank of the processing device 3 or the like.

另一方面，第2貯留槽21內的水是藉由第2送出幫浦24的送出壓力而被送出到第2流路22內。第2流路22內的水是藉由通過第2冷卻機構26而被冷卻到預定溫度。在第2流路22內的水溫為預定溫度以上的情況下，可藉由第2冷卻機構26來冷卻到預定溫度。又，在第2流路22內的水溫比預定溫度更低的情況下，則可在不以第2冷卻機構26冷卻的情形下通過。並且，冷卻後的水會在已藉由第2過濾器27移除異物的狀態下，供給到加工裝置3的驅動部4。驅動部冷卻後的水會通過循環流路23而返回到第2貯留槽21。On the other hand, the water in the second storage tank 21 is sent out into the second flow path 22 by the sending pressure of the second sending pump 24. The water in the second flow path 22 is cooled to a predetermined temperature by passing through the second cooling mechanism 26. When the temperature of the water in the second flow path 22 is equal to or higher than the predetermined temperature, the second cooling mechanism 26 can cool the temperature to the predetermined temperature. In addition, when the temperature of the water in the second flow path 22 is lower than the predetermined temperature, it can pass without cooling by the second cooling mechanism 26. In addition, the cooled water is supplied to the driving unit 4 of the processing device 3 in a state where foreign substances have been removed by the second filter 27. The water cooled by the driving part returns to the second storage tank 21 through the circulation flow path 23.

像這樣，由於對加工裝置3，會供給通過第1流路12且已調整成預定溫度的加工用的水，所以可以抑制工件之加工時的加工精度之降低。又，由於對加工裝置3中的驅動部4，會供給通過第2流路22且已冷卻到預定溫度以下的驅動部冷卻用的水，所以可以從驅動部4奪取熱以抑制驅動部4的熔執等。又，雖然驅動部冷卻後的水會吸收熱而變暖，但返回到第2貯留槽21之後，會再度在第2流路22內被冷卻到預定溫度之下，藉此可再度作為驅動部冷卻用的水而被再利用。In this manner, since the processing device 3 is supplied with water for processing that has passed through the first flow path 12 and has been adjusted to a predetermined temperature, it is possible to suppress a reduction in processing accuracy during processing of the workpiece. In addition, since the driving unit 4 in the processing device 3 is supplied with water for cooling the driving unit that has passed through the second flow path 22 and has cooled to a predetermined temperature or less, heat can be taken from the driving unit 4 to suppress the driving unit 4 Stubbornness, etc. In addition, although the water cooled by the drive unit absorbs heat and becomes warmer, after returning to the second storage tank 21, it will be cooled again below the predetermined temperature in the second flow path 22, thereby serving as the drive unit again The cooling water is reused.

如圖2B所示，在往第2貯留槽21的供水狀態下，是因應來自時序管理部42的指示，而藉由電磁閥控制部43將定溫水供給流路31的第1電磁閥33及排水流路32的第2電磁閥34開啟。藉此，開始進行從第1流路12往第2貯留槽21的供水，並且開始進行從第2貯留槽21往外部的排水。在往此第2貯留槽21的供水狀態下，當藉由第1送出幫浦14將加工用的水從第1貯留槽11送出時，會將已通過水溫調整機構16的預定溫度的水在第1流路12的中途部分處藉由定溫水供給流路31而分流。As shown in FIG. 2B, in the water supply state to the second storage tank 21, in response to an instruction from the timing management unit 42, the solenoid valve control unit 43 supplies constant temperature water to the first solenoid valve 33 of the flow path 31 And the second solenoid valve 34 of the drain channel 32 is opened. With this, the water supply from the first flow path 12 to the second storage tank 21 is started, and the drainage from the second storage tank 21 to the outside is started. In the state of water supply to the second storage tank 21, when the processing water is sent out from the first storage tank 11 through the first sending pump 14, the water having a predetermined temperature that has passed through the water temperature adjusting mechanism 16 The middle temperature of the first flow path 12 is divided by the constant temperature water supply flow path 31.

於第1流路12直進的水會從加工裝置3的噴嘴朝向加工點噴射，並透過加工裝置3的水箱等排出至外部。已流入定溫水供給流路31的水會供給到第2貯留槽21，並在第2貯留槽21中作為驅動部冷卻用的水而貯留。此時，由於已將定溫水供給流路31內的水藉由水溫調整機構16調整成預定溫度，所以不會有使已貯留於第2貯留槽21中的水的溫度大幅變動之情形。再者，由於即使因開啟第1電磁閥33而使水壓下降，第1送出幫浦14的送出壓力還是相當地高，因此仍可將加工用的水送出到加工裝置3。The water flowing straight through the first flow path 12 is sprayed from the nozzle of the processing device 3 toward the processing point, and is discharged to the outside through the water tank of the processing device 3 or the like. The water that has flowed into the constant temperature water supply flow path 31 is supplied to the second storage tank 21, and is stored in the second storage tank 21 as water for cooling the drive unit. At this time, since the water in the constant-temperature water supply flow path 31 has been adjusted to a predetermined temperature by the water temperature adjustment mechanism 16, there is no possibility that the temperature of the water stored in the second storage tank 21 will greatly change . Furthermore, even if the water pressure drops due to opening of the first solenoid valve 33, the delivery pressure of the first delivery pump 14 is still relatively high, and therefore the processing water can be delivered to the processing device 3.

另一方面，當藉由第2送出幫浦24將驅動部冷卻用的水從第2貯留槽21送出時，會在第2流路22的中途部分處藉由排水流路32而被分流。於第2流路22直進的水會藉由第2冷卻機構26而被冷卻到預定溫度以下，並供給至加工裝置3的驅動部4，進而通過循環流路23返回到第2貯留槽21中。已流入排水流路32的水會被排出到外部，以在第2貯留槽21與驅動部4之間在不純物於循環中濃縮之前將水量減少。像這樣，以相當於從定溫水供給流路31供水到第2貯留槽21的量，從第2貯留槽21通過排水流路32進行排水。On the other hand, when the water for cooling the driving section is sent out from the second storage tank 21 by the second sending pump 24, it is divided by the drain flow path 32 at the midway portion of the second flow path 22. The water flowing straight through the second flow path 22 is cooled to a predetermined temperature or lower by the second cooling mechanism 26, and is supplied to the driving section 4 of the processing device 3, and then returned to the second storage tank 21 through the circulation flow path 23 . The water that has flowed into the drain channel 32 is discharged to the outside, so that the amount of water between the second storage tank 21 and the drive unit 4 is reduced before the impurities are concentrated in the circulation. In this way, water is discharged from the second storage tank 21 through the drain flow channel 32 by an amount equivalent to the supply of water from the constant-temperature water supply flow channel 31 to the second storage tank 21.

由於可逐次少量地替換第2貯留槽21的水來抑制不純物之濃度的上升，所以不會有將不純物堆積而成的污垢供給到驅動部4之情形，而可防止驅動部4的損壞。又，由於是在使加工裝置3運轉的狀態下自動地替換第2貯留槽21內的水，所以可以減少第2貯留槽21內的水的更換作業並且縮減裝置停止所形成的停機時間。在這種情況下，較理想的是控制對第2貯留槽21的供水時序、與從第2貯留槽21的排水時序，以在24小時內替換第2貯留槽21內的水。Since the water in the second storage tank 21 can be replaced by a small amount one by one to suppress the increase in the concentration of impurities, the dirt accumulated by the impurities will not be supplied to the drive unit 4, and damage to the drive unit 4 can be prevented. In addition, since the water in the second storage tank 21 is automatically replaced with the processing device 3 in operation, the replacement work of the water in the second storage tank 21 can be reduced and the downtime caused by the stop of the device can be reduced. In this case, it is desirable to control the timing of water supply to the second storage tank 21 and the timing of drainage from the second storage tank 21 to replace the water in the second storage tank 21 within 24 hours.

如上述，由於對於第2貯留槽21會從定溫水供給流路31供給預定溫度的水，所以不會有第2貯留槽21內的水變得過低的情形。由於第2流路22內的水溫不會極端地降低，因此即便縮短加工裝置3的初期運轉前的空轉時間(空載(idling)時間)，也不致產生起因於軸承的收縮等的驅動部4的旋轉軸的擦傷等不良狀況。據此，可以將加工裝置3的初期運轉時的啟動時間提前。再者，由於即使因開啟第2電磁閥34而使水壓下降，第2送出幫浦24的送出壓力還是相當地高，因此依然可將冷卻用的水送出到驅動部4。As described above, since water of a predetermined temperature is supplied from the constant-temperature water supply flow path 31 to the second storage tank 21, the water in the second storage tank 21 does not become too low. Since the temperature of the water in the second flow path 22 does not extremely decrease, even if the idling time (idling time) before the initial operation of the processing device 3 is shortened, the driving portion due to contraction of the bearing or the like does not occur 4. Malfunctions such as scratches on the rotating shaft. According to this, the start-up time during the initial operation of the processing device 3 can be advanced. Furthermore, even if the water pressure drops due to the opening of the second solenoid valve 34, the delivery pressure of the second delivery pump 24 is still relatively high, and therefore the cooling water can be delivered to the drive unit 4.

如以上所述，在本實施形態的定溫水供給裝置1中，由於一方面可將第2貯留槽21內的驅動部冷卻用的水排出，另一方面可從第1貯留槽11將加工用的水供給至第2貯留槽21，所以可自動地替換第2貯留槽21內的水。由於一邊替換水一邊在第2貯留槽21與加工裝置的驅動部4之間循環驅動部冷卻用的水，所以不會有不純物濃度上升之情形，且不會有因不純物堆積而成的污垢之供給而導致驅動部4損壞的情形。又，由於可在將裝置持續運轉的狀態下，自動地替換第2貯留槽21內的水，所以變得不需要進行驅動部冷卻用的水的更換作業，並且可以大幅地縮減停機時間。此外，由於對第2貯留槽21會供給與排水量大致同量之經過溫度調整後的加工用的水，所以可以使驅動部冷卻用的水的溫度變動較小，進而防止因溫度變動所形成的機械故障。As described above, in the constant temperature water supply device 1 of the present embodiment, on the one hand, the water for cooling the driving part in the second storage tank 21 can be discharged, and on the other hand, the processing can be performed from the first storage tank 11 The used water is supplied to the second storage tank 21, so the water in the second storage tank 21 can be automatically replaced. Since the water for cooling the drive unit is circulated between the second storage tank 21 and the drive unit 4 of the processing device while replacing the water, there is no possibility that the concentration of impurities will increase and there will be no dirt due to the accumulation of impurities The supply causes damage to the drive unit 4. In addition, since the water in the second storage tank 21 can be automatically replaced while the device is continuously operated, it is no longer necessary to replace the water for cooling the drive unit, and the downtime can be greatly reduced. Furthermore, since the temperature-adjusted processing water is supplied to the second storage tank 21 at approximately the same amount as the drainage amount, it is possible to make the temperature variation of the cooling water of the driving unit small, and to prevent the formation of the temperature variation Mechanical failure.

再者，本發明並不受限於上述實施之形態，且可進行各種變更而實施。在上述實施形態中，關於在附圖所圖示的大小與形狀等，並不受限於此，並可在能發揮本發明的效果的範圍內作適當變更。另外，只要不脫離本發明的目的之範圍，均可以作適當的變更而實施。In addition, the present invention is not limited to the above-described embodiment, and can be implemented with various changes. In the above-mentioned embodiment, the size, shape, etc. shown in the drawings are not limited thereto, and can be appropriately changed within the range capable of exerting the effects of the present invention. In addition, as long as it does not deviate from the scope of the object of the present invention, it can be implemented with appropriate changes.

例如，在上述實施形態中，雖然是做成將第1流路12的水藉由水溫調整機構16來調整成預定溫度，並將第2流路22的水藉由第2冷卻機構26來調整成預定溫度以下之構成，但並不限定為此構成。例如，亦可為在第2流路22中不設置第2冷卻機構26，以不在第2流路22內進行水溫調整。雖然第2流路22內的水會從驅動部4奪取熱而升溫，但由於從第1流路12以預定溫度的水對第2貯留槽21進行供水，所以不會有第2流路22內的水變得過於高溫之情形，而可以持續地冷卻驅動部4。像這樣，由於可用單一的水溫調整機構16對第1流路12及第2流路22的2個系統供給預定溫度的水，所以可以減少零件數量並降低成本。For example, in the above embodiment, although the water in the first flow path 12 is adjusted to a predetermined temperature by the water temperature adjustment mechanism 16, the water in the second flow path 22 is adjusted by the second cooling mechanism 26. The structure adjusted to below the predetermined temperature is not limited to this structure. For example, the second cooling mechanism 26 may not be provided in the second flow path 22 so that the water temperature is not adjusted in the second flow path 22. Although the water in the second flow path 22 takes heat from the drive unit 4 and heats up, since the first flow path 12 supplies water to the second storage tank 21 with water of a predetermined temperature, there is no second flow path 22 If the water inside becomes too high, the drive unit 4 can be continuously cooled. In this way, since a single water temperature adjustment mechanism 16 can be used to supply water at a predetermined temperature to the two systems of the first flow path 12 and the second flow path 22, the number of parts can be reduced and the cost can be reduced.

又，在上述之實施形態中，雖然將往第2貯留槽21的供水時序、與由第2貯留槽21的排水時序同時實施，但並不限定為此構成。只要能將預定量以上的水貯留在第2貯留槽21即可，亦可將往第2貯留槽21的供水時序、與由第2貯留槽21的排水時序設成一前一後。In addition, in the above-described embodiment, the timing of water supply to the second storage tank 21 and the timing of water drainage from the second storage tank 21 are implemented at the same time, but the configuration is not limited to this. As long as the predetermined amount of water can be stored in the second storage tank 21, the timing of water supply to the second storage tank 21 and the timing of drainage from the second storage tank 21 can be set in tandem.

又，在上述之實施形態中，雖然做成在第1過濾器17的下游從第1流路12分歧而形成定溫水供給流路31之構成，但並不限定為此構成。定溫水供給流路31只要是在水溫調整機構16的下游且從第1流路12分歧而形成即可，亦可為例如讓定溫水供給流路31在第1過濾器17的上游從第1流路12分歧而形成。In the above-described embodiment, although the first filter 17 is branched downstream from the first flow path 12 to form the constant-temperature water supply flow path 31, it is not limited to this structure. The constant temperature water supply flow path 31 may be formed downstream of the water temperature adjustment mechanism 16 and diverged from the first flow path 12. For example, the constant temperature water supply flow path 31 may be upstream of the first filter 17. It diverges from the first flow path 12 and is formed.

又，在上述之實施形態中，雖然是做成使排水流路32在第2送出幫浦24與第2冷卻機構26之間從第2流路22分歧而形成之構成，但並不限定為此構成。排水流路32只要是在第2送出幫浦24的下游從第2流路22分歧而形成即可，亦可為例如排水流路32是從循環流路23分歧而形成。In addition, in the above-described embodiment, although the drainage flow path 32 is formed so as to diverge from the second flow path 22 between the second delivery pump 24 and the second cooling mechanism 26, it is not limited to This constitutes. The drain channel 32 may be formed by diverging from the second channel 22 downstream of the second delivery pump 24. For example, the drain channel 32 may be formed by diverging from the circulation channel 23.

又，在上述之實施形態中，雖然作為驅動部4而例示了主軸、工作夾台或旋轉工作台的軸馬達，但並不限定為此構成。驅動部4只要是伴隨加工裝置3的運轉而發熱之驅動部位即可，並無特別限定。 産業上之可利用性In addition, in the above-mentioned embodiment, although the shaft motor of the main shaft, the work clamp table, or the rotary table is exemplified as the drive unit 4, it is not limited to this configuration. The driving unit 4 is not particularly limited as long as it is a driving part that generates heat as the processing device 3 operates. Industrial availability
