Description

この発明は、電子部品、特に、排気ダクトを通る排気フロー内に冷却フィンを突き出した周波数変換器を備えた紡績機に関する。   The present invention relates to an electronic component, and more particularly, to a spinning machine including a frequency converter that protrudes a cooling fin into an exhaust flow passing through an exhaust duct.

紡績機は、冷却が必要な程多くの熱を発生する電子部品を有する。そのような電子部品に対して、紡績領域からの浮遊物、埃、糸屑等を吸引した排気フロー内に突き出た冷却面を設けることは周知である。それは、そのような排気フローの量が十分であることを前提としている。そのような排気フローは、フィルターによって、混ざっている汚染物を除去されるので、フィルターの堆積物が増大するにつれて、その量が低下する。そのため、フローによる冷却効果も低減する。   Spinners have electronic components that generate so much heat that they need to be cooled. It is well known to provide such an electronic component with a cooling surface protruding into the exhaust flow that sucks suspended matter, dust, lint, etc. from the spinning region. It assumes that such an exhaust flow volume is sufficient. Such exhaust flow is reduced by the filter as the filter deposits are removed so that the amount of filter deposits increases. Therefore, the cooling effect by the flow is also reduced.

以上のことから、この発明の課題は、フィルターの堆積物が増大することにより生じる電子部品の温度上昇を警告することである。   In view of the above, an object of the present invention is to warn of an increase in temperature of an electronic component caused by an increase in filter deposits.

この課題は、請求項1の特徴部に挙げた特徴によって解決される。   This problem is solved by the features listed in the characterizing part of claim 1.

第一のアプローチでは、フィルターへの汚染物の堆積増大と、それにより生じる通過する排気フロー量の低下とによって、電子部品の温度上昇が起こるものと考える。従って、先ずは、フィルターを清掃する必要性が有ることを警告する。そのような清掃を行ったにも係わらず、温度上昇が報告される場合、別の原因が有るに相違無く、その原因を探し出さなければならない。   In the first approach, it is considered that the temperature of the electronic component increases due to the increase in the accumulation of contaminants on the filter and the resulting decrease in the amount of exhaust flow passing therethrough. Therefore, first warn that there is a need to clean the filter. If a temperature increase is reported despite such cleaning, there must be another cause and the cause must be sought.

フィルター清掃の必要性に関する提示は、段階的に行うことができ、最後の段階では、電子部品の損傷を防止するために、電子部品を止めて、紡績機の操業を停止する。   The presentation regarding the need for filter cleaning can be made in stages, and in the last stage, the electronic parts are stopped and the spinning machine is stopped to prevent damage to the electronic parts.

図面には、紡績機での配置系統を平面図により模式的に図示している。   In the drawing, an arrangement system in a spinning machine is schematically shown by a plan view.

紡績機、例えば、リング紡績機又は粗紡機は、排気ダクト1を備えており、そのダクト内を、浮遊物及び/又は埃を含んだ空気が、換気扇3によって、例えば、ここでは図示されていない糸切れ吸入位置から矢印方向2に吸引される。浮遊物及び/又は埃を含んだ空気を取り込んだ後、その空気をフィルターボックス4に通して、その中の一つ以上のフィルター5により、混入している浮遊物及び/又は埃を回収する。換気扇3は、清浄化された空気を再び矢印方向6に糸道内に吹き出している。この吹出しは、放出された熱を糸道に加えないように、空調設備内に行うことも可能である。   A spinning machine, for example a ring spinning machine or a roving machine, is provided with an exhaust duct 1 in which air containing suspended matter and / or dust is not shown here, for example by means of a ventilation fan 3. Suction is performed in the direction of the arrow 2 from the thread break suction position. After taking in air containing floating substances and / or dust, the air is passed through the filter box 4, and the floating substances and / or dust mixed therein are collected by one or more filters 5 therein. The ventilation fan 3 blows out the cleaned air into the yarn path in the arrow direction 6 again. This blow-out can be performed in the air conditioning equipment so that the released heat is not applied to the yarn path.

紡績機は、複数の電気駆動モーターを有し、ここでは、例として、その中の二つを符号7と8で表示し、図示している。この場合、紡績機のスピンドル、フライヤー又はその他の動作機器に対する駆動モーターとすることができる。回転数を変更することが可能な三相交流モーターとし、その回転数を調整可能な周波数変換器9と10により決定する。配線11を介して供給される電力の周波数は、制御機器12を通し、配線13を介して周波数変換器9と10に供給される。周波数変換器9と10は、制御配線14を介して回転数信号を与えられ、その信号にもとづき、モーター配線15を介してモーター7と8に提供される、モーターを駆動するための周波数を制御する。   The spinning machine has a plurality of electric drive motors, and here, as an example, two of them are indicated by reference numerals 7 and 8 and illustrated. In this case, it can be a drive motor for a spinning machine spindle, flyer or other operating device. A three-phase AC motor capable of changing the rotation speed is determined by the frequency converters 9 and 10 which can adjust the rotation speed. The frequency of the electric power supplied through the wiring 11 is supplied to the frequency converters 9 and 10 through the control device 12 and through the wiring 13. The frequency converters 9 and 10 are supplied with the rotation speed signal via the control wiring 14 and control the frequency for driving the motor provided to the motors 7 and 8 via the motor wiring 15 based on the signal. To do.

周波数変換器9と10は、特に、整流器とインバーターを有し、それらは、避けられない熱を発生して、動作中に周波数変換器の温度を上昇させる。この熱を排出して、周波数変換器の過熱を防止するために、周波数変換器は、排気ダクト1内に充満する空気フローに突き出た冷却フィンを備えている。即ち、発生した熱は、その空気フローによって排出される。   The frequency converters 9 and 10 have in particular rectifiers and inverters, which generate unavoidable heat and raise the temperature of the frequency converter during operation. In order to discharge this heat and prevent the frequency converter from overheating, the frequency converter includes cooling fins protruding into the air flow filling the exhaust duct 1. That is, the generated heat is exhausted by the air flow.

当然のことながら、周波数変換器9と10の排熱に代わって、紡績機の別の電気又は電子部品の排熱も、排気ダクト1内の空気フローにより排出することができ、その場合同様にその空気フロー内に冷却フィンを突き出している。即ち、紡績機の電力供給を直流で行う場合、部品9,10は、インバーターだけを備えることができる。   Naturally, instead of the exhaust heat of the frequency converters 9 and 10, the exhaust heat of another electrical or electronic part of the spinning machine can also be exhausted by the air flow in the exhaust duct 1, in that case as well. A cooling fin protrudes into the air flow. That is, when the spinning machine is supplied with direct current, the components 9 and 10 can include only an inverter.

排気ダクト1内での十分な熱を排出、冷却するための空気フロー2は、その量がフィルター5への浮遊物と埃の堆積によって大幅に絞り込まれ過ぎない場合にのみ得られる。従って、フィルターを時々又は定期的に清掃する必要が有る、即ち、堆積物を除去する必要が有る。それを行わない場合、十分な熱の排出が行われず、過熱して、電気又は電子部品、即ち、例えば、周波数変換器9,10が故障する可能性が有る。   An air flow 2 for exhausting and cooling sufficient heat in the exhaust duct 1 is obtained only when the amount is not significantly reduced due to suspended matter and dust accumulation on the filter 5. Therefore, it is necessary to clean the filter from time to time or periodically, i.e. to remove deposits. If this is not done, sufficient heat is not drained and overheating can cause electrical or electronic components, for example, frequency converters 9, 10 to fail.

そういうことを防止、保証するために、電子部品9,10は、温度計17を備えており、この温度計は、所定の温度を上回った場合に、信号配線18又は19を介して制御機器12に信号を出力する。この信号は、到達している温度の高さに依存して符号化することができる、即ち、例えば、温度が上昇するに従って増大させることができる。この信号に対する制御機器の反応は、段階的に行うことができる。   In order to prevent or guarantee such a situation, the electronic components 9 and 10 are provided with a thermometer 17, and when the thermometer exceeds a predetermined temperature, the control device 12 is connected via the signal wiring 18 or 19. To output a signal. This signal can be encoded depending on the height of the temperature reached, i.e. it can be increased as the temperature increases, for example. The response of the control device to this signal can be performed in stages.

制御機器12は、先ずディスプレイ20上にフィルター5を清掃する必要性が有ることを表示することができる。一定の時間内に対処されなかった場合、或いは信号が更に高い温度を報告してきた場合、光学的な表示機器21を用いて、或いは音響信号により、清掃する必要性が有ることを提示することができる。フィルター5の清掃後においても、一つ以上の電子部品の温度が低下しない場合、別の原因が有るに相違無く、その原因を探し出さなければならない。   The control device 12 can display on the display 20 that it is necessary to clean the filter 5 first. If not addressed within a certain time, or if the signal reports a higher temperature, it may indicate that there is a need to clean using the optical display device 21 or by an acoustic signal. it can. If the temperature of one or more electronic components does not decrease even after the filter 5 is cleaned, there must be another cause and the cause must be found.

一つの電気又は電子部品の温度が、それを故障させる虞の有る高さに達した場合、制御機器12は、最終的に電力の供給を停止することができ、その目的のために、電力供給線11/13が、この制御機器を介して配線されている。しかし、多くの場合、制御機器が制御した形で駆動を停止させるのが、その目的に適ったことである。そうすることによって、障害、例えば、糸切れなどが防止される。   If the temperature of one electrical or electronic component reaches a height that could cause it to fail, the control device 12 can eventually stop supplying power, and for that purpose, the power supply Lines 11/13 are routed through this control device. However, in many cases, it is suitable for the purpose to stop the drive in a form controlled by the control device. By doing so, obstacles such as thread breakage are prevented.

電気又は電子部品9,10の冷却フィン16は、浮遊物と埃が付着しないように、排気ダクト1を通る空気フローの方向に対してフィルターボックス4の後で、排気ダクト1内に、そのため清浄化された空気フロー内に突き出ている。排気ダクトは、有利には、その領域に、冷却フィンを容易に取り付けることが可能な平坦な壁面を有する。   The cooling fins 16 of the electrical or electronic components 9, 10 are therefore cleaned in the exhaust duct 1 after the filter box 4 with respect to the direction of air flow through the exhaust duct 1 so that no suspended matter and dust adhere. Protrudes into the conditioned air flow. The exhaust duct advantageously has a flat wall in its area to which the cooling fins can be easily attached.

冷却フィン16は、清浄化された空気フロー内に突き出ており、そのため汚染に曝されていない。しかし、フィルター5は、通常微粒子を回収しないので、排気ダクト1の冷却フィンと対向する側に、取り外し可能な蓋で閉鎖された開口部22を配置して、時々冷却フィンの微粒子を取り除くために、その開口部を通して、冷却フィンにアクセスすることを可能としている。   The cooling fins 16 protrude into the cleaned air flow and are therefore not exposed to contamination. However, since the filter 5 normally does not collect fine particles, an opening 22 closed with a removable lid is arranged on the side of the exhaust duct 1 facing the cooling fin to remove the fine particles of the cooling fin from time to time. The cooling fins can be accessed through the openings.
