具抑制噪音功能之分紙裝置、自動饋紙裝置及製造方法Paper separation device with noise suppression function, automatic paper feeding device and manufacturing method

本案係關於一種分紙裝置、自動饋紙裝置及製造方法,尤指一種具抑制噪音功能之分紙裝置、自動饋紙裝置及製造方法。The present invention relates to a paper separation device, an automatic paper feeding device and a manufacturing method thereof, and more particularly to a paper separation device, an automatic paper feeding device and a manufacturing method having a noise suppression function.

隨著電子技術的大幅進步,現今辦公室中所有的庶務工作都與影印機、傳真機、印表機、掃描器等事務機息息相關,使得不論是單功能事務機或多功能事務機皆成為辦公室內不可或缺的影像處理設備。為了使得工作流程更加快速正確,能夠連續地將複數張疊置於供紙盤上的紙張(例如原稿)逐一傳送至影像處理設備內進行傳真、列印或掃描的自動饋紙裝置(Auto Document Feeder,ADF)也就成為影像處理設備的基本配備。With the advancement of electronic technology, all the work in today's office is closely related to photocopiers, fax machines, printers, scanners, etc., making it a single-function machine or a multi-function machine. An indispensable image processing device. In order to make the workflow faster and more accurate, it is possible to continuously transfer a plurality of sheets (such as originals) stacked on the paper feed tray one by one to the automatic paper feeding device for faxing, printing or scanning in the image processing apparatus (Auto Document Feeder) , ADF) has become the basic equipment of image processing equipment.

請參閱第一圖,其係顯示傳統之自動饋紙裝置之部分結構示意圖。如圖所示,傳統自動饋紙裝置1係包含供紙盤10(sheet feeding tray)、送紙裝置11(sheet feeding device)、分紙裝置12(sheet separating device)以及驅動裝置(未圖示),其中供紙盤10可用於疊置複數張紙張,驅動裝置可為驅動馬達。送紙裝置11與驅動裝置連接,以藉由驅動裝置的驅動而將複數張疊置於供紙盤10上的紙張(例如原稿)逐一傳送至導紙路徑13中,以利於傳送至影像處理設備內進行影像處理。分紙裝置12係設置於導紙路徑13之入口端,且鄰設於送紙裝置11,以用於與送紙裝置11相配合而將送紙裝置11所傳送之紙張分離,俾使紙張可以逐一且不重疊地被傳送至導紙路徑13中。Please refer to the first figure, which shows a partial structural diagram of a conventional automatic paper feeding device. As shown in the figure, the conventional automatic paper feeding device 1 includes a sheet feeding tray, a sheet feeding device 11, a sheet separating device, and a driving device (not shown). The paper feed tray 10 can be used to stack a plurality of sheets of paper, and the driving device can be a drive motor. The paper feeding device 11 is connected to the driving device to transfer a plurality of sheets (for example, originals) stacked on the paper feeding tray 10 one by one to the paper guiding path 13 by driving of the driving device, so as to facilitate transmission to the image processing device. Image processing is performed inside. The paper separating device 12 is disposed at the inlet end of the paper guiding path 13 and adjacent to the paper feeding device 11 for cooperating with the paper feeding device 11 to separate the paper conveyed by the paper feeding device 11 so that the paper can be They are transferred to the paper guide path 13 one by one and without overlapping.

當自動饋紙裝置1接收到工作指令時,驅動裝置啟動並且驅動送紙裝置11進行供紙,此時送紙裝置11之分紙滾輪113會因應驅動裝置之驅動而開始轉動,且送紙裝置11之取紙滾輪111逐漸往供紙盤10方向下降,直到與最上方紙張的表面接觸後,取紙滾輪111便藉由轉動以及摩擦力將紙張傳送至導紙路徑13。然而,在驅動裝置啟動、送紙裝置11之分紙滾輪113轉動,以及取紙滾輪111傳送至導紙路徑13之紙張尚未與分紙滾輪113以及分紙裝置12接觸時,常會有很大的噪音產生,直到紙張通過分紙滾輪113以及分紙裝置12之間時噪音才會降低。此外,在最後一張紙張離開分紙滾輪113與分紙裝置12間之導紙路徑13時,驅動裝置仍持續運作,分紙滾輪113仍會轉動,且取紙滾輪111須一段時間回復到原位置,在分紙滾輪113空轉且與分紙裝置12摩擦接觸的這段期間,仍會有很大的噪音產生,直到取紙滾輪111回復到原位置,驅動裝置以及分紙滾輪113停止運轉時噪音才會消失。When the automatic paper feeding device 1 receives the work instruction, the driving device starts and drives the paper feeding device 11 to perform paper feeding. At this time, the paper separating roller 113 of the paper feeding device 11 starts to rotate according to the driving of the driving device, and the paper feeding device The paper take-up roller 111 of FIG. 11 gradually descends toward the paper feed tray 10 until the paper contact roller 111 conveys the paper to the paper guide path 13 by the rotation and the frictional force after coming into contact with the surface of the uppermost paper. However, when the driving device is activated, the separation roller 113 of the paper feeding device 11 is rotated, and the paper conveyed by the pickup roller 111 to the paper guiding path 13 has not been in contact with the separation roller 113 and the paper separating device 12, there is often a large Noise is generated until the paper passes between the separation roller 113 and the separation device 12, and the noise is lowered. In addition, when the last sheet of paper leaves the paper guide path 13 between the separation roller 113 and the separation device 12, the driving device continues to operate, the separation roller 113 still rotates, and the pickup roller 111 needs to return to the original state for a while. At the position, during the period in which the separation roller 113 is idling and in frictional contact with the separation device 12, a large noise is still generated until the pickup roller 111 returns to the original position, and the driving device and the separation roller 113 are stopped. The noise will disappear.

雖然,自動饋紙裝置1之分紙滾輪113與分紙裝置12間的摩擦可能是造成噪音的因素,但經過改變分紙裝置12之材質或使其具有不同摩擦係數表面的方式,仍無法有效改善噪音的問題,甚至可能會導致使用者誤認影像處理設備已產生故障或者有零件鬆脫的情形。因此,如何顯著地改善傳統自動饋紙裝置於運作時所產生的噪音問題,實為長久以來一直無法解決且有待克服之問題。Although the friction between the separation roller 113 of the automatic paper feeding device 1 and the separation device 12 may be a cause of noise, it is still not effective by changing the material of the separation device 12 or having a surface having a different friction coefficient. Improving the noise problem may even cause the user to misunderstand that the image processing equipment has failed or has loose parts. Therefore, how to significantly improve the noise generated by the conventional automatic paper feeding device during operation is a problem that has been unsolved for a long time and needs to be overcome.

In some embodiments, the separation pad 221 can be fixed to the first surface 222a of the separation seat 222 by means of adhesive, locking or securing. A vibration absorbing member (not shown) such as a sponge or the like may be disposed between the paper separation pad 221 and the paper separation base 222. The separation seat 222 further has a second surface 222b, such as a bottom surface, and the second surface 222b is biased or connected to the elastic member 223 with respect to the first surface 222a. The paper separating base 222 has a shaft portion 222c on two adjacent sides of one side, and can be fixed inside the automatic paper feeding device 2 as a rotating shaft of the paper separating base 222. The separation seat 222 has support members 222d on two adjacent sides of the other side, and the support member 222d can support the separation seat 222.

One end of the elastic member 223 is disposed on the inner surface of the casing of the automatic paper feeding device 2, and the other end is abutted or connected to the second surface 222b of the paper separation seat 222, thereby using the elastic force to cause the paper separation seat 222 to carry the paper separation pad. The 211 is pressed against the separation roller 213 to bring the separation pad 211 into contact with the first friction layer 213a of the separation roller 213 or with the paper passing between the separation roller 213 and the separation pad 221. In some embodiments, the separation device 22 further includes a separation film 225 disposed on a portion of the surface of the separation pad 221 to facilitate guiding the paper between the separation roller 213 and the separation pad 221 . The separation film 225 can be composed of, for example, polyethylene terephthalate (Mylar, commonly known as Mylar).

噪音抑制元件224之設置主要係藉由調整或改變分紙墊221與分紙座222組合之總重量的方式,來改變或偏移分紙墊221與分紙座222組合之自然頻率特性,使其動態響應不與分紙滾輪213之工作頻率(Working frequency)以及諧振頻率(Harmonic frequency)重疊,以避免共振(resonance)現象產生,而達到顯著抑制自動饋紙裝置2於運作時產生噪音之效果。請參閱第三圖、第四圖A與第四圖B,噪音抑制元件224可以是例如金屬塊224a,但不以此為限,噪音抑制元件224可設置於分紙座222之第二表面222b,俾藉由增加分紙墊221與分紙座222組合之總重量,以改變或偏移其自然頻率特性。噪音抑制元件224可利用黏貼(未圖示)、鎖固元件226鎖固或夾具夾固(未圖示)之方式固定於分紙座222之第二表面222b上。於一些實施例中,如第五圖所示,噪音抑制元件224亦可以是一或複數個通孔224b,設置於分紙座222中,俾藉由降低分紙墊221與分紙座222組合之總重量,以改變或偏移其自然頻率特性。The noise suppression component 224 is mainly configured to change or shift the natural frequency characteristics of the combination of the separation pad 221 and the separation tray 222 by adjusting or changing the total weight of the combination of the separation pad 221 and the separation tray 222. The dynamic response does not overlap with the working frequency and the Harmonic frequency of the separation roller 213 to avoid the occurrence of resonance, and the effect of suppressing the noise generated by the automatic paper feeding device 2 during operation is significantly suppressed. . Please refer to the third figure, the fourth figure A and the fourth figure B. The noise suppression component 224 can be, for example, a metal block 224a, but not limited thereto, the noise suppression component 224 can be disposed on the second surface 222b of the paper separation seat 222. , by changing the total weight of the separation pad 221 and the separation tray 222 to change or shift its natural frequency characteristics. The noise suppression element 224 can be secured to the second surface 222b of the separation deck 222 by means of a sticker (not shown), a locking element 226, or a clamp (not shown). In some embodiments, as shown in FIG. 5, the noise suppression component 224 may also be one or more through holes 224b disposed in the paper separation base 222, by combining the separation paper pad 221 and the paper separation base 222. The total weight to change or offset its natural frequency characteristics.

根據本案之構想,當自動饋紙裝置2之分紙滾輪213之工作頻率(Working frequency)以及諧振頻率(Harmonic frequency)與分紙墊221與分紙座222組合之自然頻率動態響應(dynamic response)有接近或重疊的現象產生時,便會產生共振而造成刺耳的噪音。因此,本案之分紙裝置製造方法係藉由改變或調整分紙墊221與分紙座222組合之總重量的方式,來改變或偏移分紙墊221與分紙座222組合之自然頻率特性,使其動態響應不與分紙滾輪213之工作頻率(Working frequency)以及諧振頻率(Harmonic frequency)重疊,以避免共振(resonance)產生,而達到顯著抑制自動饋紙裝置2於運作時產生噪音之效果。According to the concept of the present invention, the working frequency and the resonance frequency (Harmonic frequency) of the separation roller 213 of the automatic paper feeding device 2 and the natural frequency dynamic response of the separation pad 221 and the paper separation base 222 are combined. When there is a phenomenon of closeness or overlap, resonance occurs and a harsh noise is generated. Therefore, the papermaking device manufacturing method of the present invention changes or shifts the natural frequency characteristics of the combination of the paper separation pad 221 and the paper separation base 222 by changing or adjusting the total weight of the combination of the separation paper pad 221 and the separation paper base 222. The dynamic response does not overlap with the working frequency and the Harmonic frequency of the separation roller 213 to avoid resonance, and the noise of the automatic paper feeding device 2 during operation is significantly suppressed. effect.

請參閱第六圖,係為本案較佳實施例之分紙裝置之製造方法流程圖。如第六圖所示,首先,如步驟S11所示,藉由分析與計算,取得分紙滾輪之工作頻率與諧振頻率。接著,如步驟S12所示,依據分紙滾輪之工作頻率與諧振頻率,調整或改變分紙裝置之分紙墊以及分紙座組合之總重量,使其所具有之自然頻率動態響應與分紙滾輪之工作頻率以及諧振頻率偏移(shift)且不重疊。依據本案之構想,於步驟S12中,本案之方法可為預先計算出可以使其自然頻率動態響應與分紙滾輪213之工作頻率以及諧振頻率不重疊之分紙墊221以及分紙座222組合之總重量,然後直接形成一體成形之分紙座222。於一些實施例中,本案之方法可利用噪音抑制元件224,例如金屬塊224a,增加或調整分紙墊221以及分紙座222組合之總重量,以使其自然頻率動態響應與分紙滾輪213之工作頻率以及諧振頻率偏移且不重疊。於另一些實施例中,本案之方法可利用噪音抑制元件224,例如通孔224b,降低分紙墊221以及分紙座222組合之總重量,以使其自然頻率動態響應與分紙滾輪之工作頻率以及諧振頻率偏移且不重疊。Please refer to the sixth drawing, which is a flow chart of a manufacturing method of the paper separating device of the preferred embodiment of the present invention. As shown in the sixth figure, first, as shown in step S11, the operating frequency and the resonance frequency of the separation roller are obtained by analysis and calculation. Then, as shown in step S12, according to the working frequency and the resonance frequency of the separation roller, adjust or change the total weight of the separation pad and the separation base of the separating device to make the natural frequency dynamic response and the separation The operating frequency of the scroll wheel and the resonant frequency shift and do not overlap. According to the concept of the present invention, in the step S12, the method of the present invention may be pre-calculated by combining the paper separation pad 221 and the paper separation seat 222, which can make the natural frequency dynamic response and the working frequency and the resonance frequency of the separation roller 213 do not overlap. The total weight is then directly formed into an integrally formed separation block 222. In some embodiments, the method of the present invention can utilize the noise suppression component 224, such as the metal block 224a, to increase or adjust the total weight of the combination of the separation pad 221 and the separation deck 222 to have its natural frequency dynamic response and the separation roller 213. The operating frequency and the resonant frequency are offset and do not overlap. In other embodiments, the method of the present invention can utilize the noise suppression component 224, such as the through hole 224b, to reduce the total weight of the combination of the separation pad 221 and the separation pad 222 to allow the natural frequency dynamic response and the operation of the separation roller. The frequency and resonant frequency are offset and do not overlap.

舉例而言,當驅動裝置,例如驅動馬達,以一設定轉速驅動時,例如以2500pps轉動時,分紙滾輪之工作頻率為例如53.48Hz,其諧振頻率表列於表一。For example, when the driving device, for example, the driving motor, is driven at a set rotational speed, for example, at 2500 pps, the operating frequency of the separating roller is, for example, 53.48 Hz, and the resonant frequency thereof is shown in Table 1.

當分紙裝置22之分紙墊221與分紙座222組合之總重量為例如4.2克時,經實驗量測與計算可知分紙墊221與分紙座222組合之自然頻率動態響應如表二之A欄所示。另外,當以噪音抑制元件224,例如金屬塊224a,增加與調整分紙墊221與分紙座222組合之總重量時,例如由重量4.2g增加至8.8g時,分紙墊221與分紙座222之自然頻率動態響應如表二之B欄所示。此外,當以噪音抑制元件224,例如通孔224b,降低分紙墊221與分紙座222組合之總重量時,例如由重量4.2g降低至2.1g時,分紙墊221與分紙座222之自然頻率動態響應如表二之C欄所示。When the total weight of the paper separation pad 221 and the paper separation base 222 of the paper separation device 22 is, for example, 4.2 grams, the natural frequency dynamic response of the paper separation pad 221 and the paper separation base 222 is shown by the experimental measurement and calculation. It is shown in column A. In addition, when the total weight of the combination of the separation separation pad 221 and the separation tray 222 is increased by the noise suppression member 224, for example, the metal block 224a, for example, when the weight is increased from 4.2 g to 8.8 g, the separation pad 221 and the separation paper The natural frequency dynamic response of the seat 222 is shown in column B of Table 2. Further, when the total weight of the combination of the separation pad 221 and the separation tray 222 is reduced by the noise suppression member 224, for example, the through hole 224b, for example, when the weight is reduced from 4.2 g to 2.1 g, the separation pad 221 and the separation pad 222 are used. The natural frequency dynamic response is shown in column C of Table 2.

第七圖係顯示分紙墊與分紙座組合之自然頻率動態響應與振幅之關係圖。如表一,表二以及第七圖所示,當分紙滾輪213之工作頻率及諧振頻率與分紙墊221及分紙座222之自然頻率動態響應相近或重疊時,例如分紙滾輪213之工作頻率及諧振頻率之第8諧振頻率427.84Hz與分紙墊221與分紙座222組合之自然頻率動態響應之第1模態(modal)相近時,則會使分紙墊221與分紙座222產生共振。於此情況下,即使改變其他因素,例如改變材料、改變彈性元件之彈性係數等等,皆僅能輕微地改善噪音而無法顯著地抑制噪音產生,這是因為共振的結果將使振幅加大,無法顯著地抑制噪音產生。因此,為有效抑制噪音問題,可以將分紙墊221與分紙座222組合之自然頻率動態響應與分紙滾輪213之工作頻率以及諧振頻率偏移,使其不會有接近或重疊的現象,如此可以避免產生共振而可以顯著地抑制噪音。The seventh figure shows the relationship between the natural frequency dynamic response and the amplitude of the combination of the separation pad and the separation table. As shown in Table 1, Table 2 and Figure 7, when the operating frequency and resonance frequency of the separation roller 213 are close to or overlap with the natural frequency dynamic response of the separation pad 221 and the separation tray 222, for example, the separation roller 213 When the eighth resonant frequency of the operating frequency and the resonant frequency is 427.84 Hz and the first mode of the natural frequency dynamic response of the combination of the paper separating pad 221 and the paper separating base 222 is similar, the paper separating pad 221 and the paper separating base are provided. 222 produces resonance. In this case, even if other factors are changed, such as changing the material, changing the elastic modulus of the elastic member, etc., the noise can be slightly improved without significantly suppressing the noise generation, because the result of the resonance will increase the amplitude. Noise generation cannot be significantly suppressed. Therefore, in order to effectively suppress the noise problem, the natural frequency dynamic response of the separation pad 221 and the separation tray 222 can be offset from the operating frequency and the resonance frequency of the separation roller 213 so that there is no closeness or overlap. This avoids resonance and can significantly suppress noise.

於此系統中,當分紙墊221與分紙座222組合之總重量為4.2g(未增加或降低總重量),分紙滾輪213之工作頻率以及諧振頻率之第8諧振頻率427.84Hz與分紙墊213與分紙座222組合之自然頻率動態響應之第1模態(modal)418Hz相近,因此抑制噪音之效果相對有限。當分紙墊221與分紙座222組合之總重量調整或降低為2.2g,分紙滾輪213之工作頻率以及諧振頻率之第8諧振頻率427.84Hz與分紙墊213與分紙座222組合之自然頻率動態響應之第1模態(modal)425Hz相近,因此抑制噪音之效果亦相對有限,其中原總重量抑制噪音的效果較降低總重量抑制噪音的效果為佳。然而,若以噪音抑制元件224來增加分紙墊221與分紙座222組合之總重量為8.8g時,分紙滾輪213之工作頻率以及諧振頻率之第8諧振頻率427.84Hz與分紙墊213與分紙座222組合之自然頻率動態響應之第1模態(modal)270Hz相較可以顯著偏移,如此可以有效避免共振現象的產生,可達到顯著抑制噪音之效果。因此,於自動饋紙裝置以及分紙裝置製造或出廠前,皆可透過本案之方式達到避免共振現象產生以及可以顯著抑制噪音之效果。In this system, when the total weight of the separation pad 221 and the separation tray 222 is 4.2 g (no increase or decrease in total weight), the operating frequency of the separation roller 213 and the eighth resonance frequency of the resonance frequency are 427.84 Hz and minutes. The first modal 418 Hz of the natural frequency dynamic response of the paper pad 213 combined with the paper separation base 222 is similar, so the effect of suppressing noise is relatively limited. When the total weight of the combination of the separation pad 221 and the separation tray 222 is adjusted or lowered to 2.2 g, the operating frequency of the separation roller 213 and the eighth resonance frequency of the resonance frequency of 427.84 Hz are combined with the separation pad 213 and the separation tray 222. The first mode of the natural frequency dynamic response is similar to the modal 425 Hz, so the effect of suppressing noise is relatively limited, and the effect of suppressing the noise by the original total weight is better than the effect of reducing the total weight suppressing noise. However, if the total weight of the combination of the separation pad 221 and the separation tray 222 is 8.8 g by the noise suppression member 224, the operating frequency of the separation roller 213 and the eighth resonance frequency of the resonance frequency are 427.84 Hz and the separation pad 213. The first mode modal 270 Hz of the natural frequency dynamic response combined with the paper separator 222 can be significantly shifted, so that the resonance phenomenon can be effectively avoided, and the effect of significantly suppressing noise can be achieved. Therefore, in the case of the automatic paper feeding device and the paper separating device manufactured or shipped from the factory, the effect of avoiding the resonance phenomenon and the noise suppression can be achieved by the method of the present invention.

當然,於其他實施例中,在不同之自動饋紙裝置中,當分紙滾輪213以不同工作頻率以及諧振頻率進行時,分紙裝置22之分紙墊221與分紙座222組合亦可能以降低總重量之方式較以原總重量或增加總重量之方式具有更好的抑制噪音效果,可依據實際應用而調整。因此,藉由改變或調整分紙墊221與分紙座222組合之總重量的方式,來改變或偏移分紙墊221與分紙座222組合之自然頻率特性,使其自然頻率動態響應與分紙滾輪213之工作頻率以及諧振頻率不重疊,可避免共振(resonance)現象產生,而達到顯著抑制自動饋紙裝置2於運作時產生噪音之效果。Of course, in other embodiments, in different automatic paper feeding devices, when the separation rollers 213 are operated at different operating frequencies and resonant frequencies, the combination of the separation pad 221 of the separation device 22 and the separation tray 222 may also be The method of lowering the total weight has better noise suppression effect than the original total weight or increasing the total weight, and can be adjusted according to practical applications. Therefore, by changing or adjusting the total weight of the combination of the separation pad 221 and the separation tray 222, the natural frequency characteristics of the combination of the separation pad 221 and the separation tray 222 are changed or offset, so that the natural frequency dynamic response and The operating frequency and the resonance frequency of the separation roller 213 do not overlap, thereby avoiding the occurrence of resonance, and the effect of suppressing the noise generated by the automatic paper feeding device 2 during operation is remarkably suppressed.

綜上所述,由於長久以來皆無法找出自動饋紙裝置真正產生噪音之原因以及提出有效的抑制噪音方法,因此抑制噪音之效果有限。本案藉由改變或調整分紙墊221與分紙座222組合之總重量的方式,來改變或偏移分紙墊221與分紙座222組合之自然頻率特性,使其自然頻率動態響應與分紙滾輪213之工作頻率以及諧振頻率不重疊,可避免共振(resonance)產生,而達到顯著抑制自動饋紙裝置2於運作時產生噪音之效果。此外,採用本案之方式不只結構簡單、易於實施,且成本低。In summary, since the reason why the automatic paper feeding device actually generates noise and the effective noise suppression method have not been found for a long time, the effect of suppressing noise is limited. In this case, by changing or adjusting the total weight of the combination of the separation pad 221 and the separation tray 222, the natural frequency characteristics of the combination of the separation pad 221 and the separation tray 222 are changed or offset, so that the natural frequency dynamic response and the score are divided. The operating frequency and the resonance frequency of the paper roller 213 do not overlap, and resonance can be avoided, and the effect of the noise generated by the automatic paper feeding device 2 during operation is remarkably suppressed. In addition, the method of using this case is not only simple in structure, easy to implement, but also low in cost.
