Description
本發明涉及一種可避免夾紙以及因夾紙而損害紙張的自動饋紙器，尤其指一種直接量測紙張動態以及時對夾紙狀況進行反應的防夾紙自動饋紙器。
The present invention relates to an automatic paper feeder which can avoid paper jam and damage paper due to paper jamming, and more particularly to an paper jam automatic paper feeder which directly measures paper dynamics and reacts to paper jam conditions.
請參閱第一圖，為了避免輸送紙張時發生卡紙或夾紙的現象，必須使自動饋紙器的送紙路徑１０保持通暢，且進紙時要避免同時將一張以上的紙張送入送紙路徑１０中。因此一般自動饋紙器在進紙機構的下游會設置有避免重複進紙的分紙機構３０。常見的分紙機構３０可如第一圖中所示，利用分紙輪３１搭配被動惰輪３２而成的機械式分紙機構３０，或者是進一步利用超音波感應器３３量測紙張厚度，並在發生重複進紙時停止進紙。但即使在進紙時完全避免重複進紙，紙張在輸送的過程中仍有可能受到異常阻力而產生卡紙Referring to the first figure, in order to avoid paper jam or paper jam when conveying paper, the paper path of the automatic paper feeder must be kept clear, and it is necessary to avoid feeding more than one sheet of paper at the same time. In path 10. Therefore, the general automatic paper feeder is provided with a paper separating mechanism 30 for avoiding repeated paper feeding downstream of the paper feeding mechanism. The common paper separating mechanism 30 can use the mechanical paper separating mechanism 30 formed by the paper separating wheel 31 and the passive idler gear 32 as shown in the first figure, or further measure the paper thickness by using the ultrasonic sensor 33, and Stop feeding when duplicate feed occurs. However, even if the paper feed is completely avoided during paper feeding, the paper may still be subjected to abnormal resistance and jam during the conveyance process.
而且，上述防止重複進紙之機制均以間接方式判斷紙張輸送狀態，無法準確判斷卡紙狀態。舉例來說，重複進紙的現象在卡紙初期並不一定會伴隨發生。因此一般自動饋紙器在感測到卡紙發生時往往已經太遲，等到真正停止送紙時紙張大多已遭受無法復原的損害。Moreover, the above mechanism for preventing repeated paper feeds judges the paper conveyance state in an indirect manner, and cannot accurately judge the jam state. For example, the phenomenon of repeated feeding does not necessarily occur at the beginning of the jam. Therefore, the automatic paper feeder is often too late when it senses that a paper jam has occurred, and most of the paper has suffered irreparable damage when the paper feed is actually stopped.
有鑑於以上缺點，實有必要對現有自動饋紙器加以改良，以提供一種能夠在早期對卡紙狀態提供預警，以減少紙張損害的防夾紙自動饋紙器。In view of the above shortcomings, it is necessary to improve the existing automatic paper feeder to provide an anti-pinch automatic paper feeder capable of providing early warning of the jam state to reduce paper damage.

為詳細說明本發明之技術內容、構造特徵、所達成的目的及功效，以下茲舉例並配合圖式詳予說明。In order to explain the technical contents, structural features, objects and effects of the present invention in detail, the following detailed description is given by way of example.
現請參閱第三圖與第四圖，以下以掃描機進行說明。該掃描機具有一送紙路徑１０，且由送紙路徑１０的上游至下游分別設置有進紙匣１１，用以對齊並暫時儲放待掃描的原稿；本發明的防夾紙自動饋紙器２０，將進紙匣１１中的原稿逐張取出並饋送通過送紙路徑１０；一掃描單元４０，設置於送紙路徑１０上以掃描原稿影像；以及一出紙匣１２，設置於送紙路徑１０的末端並儲放掃描完畢的原稿。Please refer to the third and fourth figures. The following is a description of the scanner. The scanner has a paper feed path 10, and a paper feed cassette 11 is disposed from upstream to downstream of the paper feed path 10 for aligning and temporarily storing the original to be scanned; the paper jam automatic paper feeder 20 of the present invention The originals in the paper feed cassette 11 are taken out one by one and fed through the paper feed path 10; a scanning unit 40 is disposed on the paper feed path 10 to scan the original image; and a paper output tray 12 is disposed on the paper feed path 10 At the end, the scanned original is stored.
而本發明中的防夾紙自動饋紙器２０由送紙路徑１０的上游往下游依序設有一取紙裝置２１，設置於送紙路徑１０上游以將紙張饋入送紙路徑１０中；一組輸送裝置２２，設置於送紙路徑１０上以輸送紙張；一動態量測模組２３，設置於送紙路徑１０上並用以測量紙張的移動速度及移動方向等資訊；以及一控制單元２４，與動量測模組及取紙裝置２１訊號相連，並在紙張的移動速度或移動方向發生異常時暫停取紙裝置２１。The anti-pinch automatic paper feeder 20 of the present invention is provided with a paper taking device 21 from the upstream to the downstream of the paper feeding path 10, and is disposed upstream of the paper feeding path 10 to feed the paper into the paper feeding path 10; The conveying device 22 is disposed on the paper feeding path 10 for conveying the paper; a dynamic measuring module 23 is disposed on the paper feeding path 10 for measuring information such as the moving speed and the moving direction of the paper; and a control unit 24, The momentum measuring module and the paper picking device 21 are connected to each other, and the paper picking device 21 is suspended when an abnormality occurs in the moving speed or moving direction of the paper.
在此一實施例中，上述動態量測模組２３包含一攝像單元，該攝像單元固定在送紙路徑１０上以連續拍攝紙張行進時的局部影像，藉著紙張的局部影像可得知紙張與攝影單元之間的相對位置。並藉由比對不同局部影像之間的偏移量而求得紙張的移動速度以及紙張的移動方向。In this embodiment, the dynamic measurement module 23 includes an image capturing unit that is fixed on the paper feeding path 10 to continuously capture a partial image of the paper as it travels, and the paper can be known by the partial image of the paper. The relative position between the photography units. And by moving the offset between the different partial images, the moving speed of the paper and the moving direction of the paper are obtained.
請參閱第五圖，如圖中所示，當紙張在送紙路徑１０中移動的時候，攝像單元同時以極短的時間間隔連續且快速的拍攝通過的紙張局部表面。在第Ｔ秒時所截取到的局部影像為Ａ而在第Ｔ’秒時所截取到的局部影像為Ａ’。藉著比對Ａ以及Ａ’之間的相對偏移量可求得紙張的即時移動速度以及移動方向。Referring to the fifth figure, as shown in the drawing, when the paper is moved in the paper feed path 10, the image pickup unit simultaneously and continuously photographs the passing paper partial surface at extremely short time intervals. The partial image captured at the Tth second is A and the partial image captured at the T' second is A'. The instantaneous moving speed of the paper and the moving direction can be obtained by comparing the relative offset between A and A'.
再請參閱第六Ａ圖至第六Ｃ圖，如圖中所示，在正常送紙的過程中，紙張的移動方向將會沿著送紙路徑１０的方向，且以預定的送紙速度移動。若紙張的移動方向正常，但移動速度低於預定速度則表示紙張可能已受到異常的阻力並發生卡紙的現象。相對的，當紙張的移動速度正常，但是紙張的移動方向與送紙路徑１０的方向偏斜了，則紙張可預期的將會撞上送紙路徑１０的邊緣並造成卡紙。因此當控制單元２４監測到紙張的移動方向或移動速度發生異常時，便控制取紙裝置２１與輸送裝置２２停止取紙與送紙，以避免紙張因卡紙而受損。Referring to FIGS. 6A to 6C, as shown in the figure, in the normal paper feeding process, the moving direction of the paper will follow the direction of the paper feeding path 10 and move at a predetermined paper feed speed. . If the paper moves in the normal direction, but the moving speed is lower than the predetermined speed, it means that the paper may have been subjected to abnormal resistance and a paper jam has occurred. In contrast, when the moving speed of the paper is normal, but the moving direction of the paper is skewed with the direction of the paper feeding path 10, the paper can be expected to hit the edge of the paper feeding path 10 and cause a jam. Therefore, when the control unit 24 detects that the moving direction or the moving speed of the paper is abnormal, the paper picking device 21 and the conveying device 22 are controlled to stop the paper picking and paper feeding to prevent the paper from being damaged due to the paper jam.
請參閱第七圖，於圖中所示的另一實施例中動態量測裝置包含一第一量測輪２５以及一第二量測輪２６，第一量測輪２５與第二量測輪２６分別經由一組傳動機構２９而與第一軸編碼器２７與第二軸編碼器２８相連接，其中第一量測輪２５與第二量測輪２６分別被固定在送紙路徑１０上的左右兩側，並與送紙路徑１０中紙張的左右兩側接觸，則當紙張通過送紙路徑１０時第一量測輪２５與第二量測輪２６將隨著紙張而轉動。再透過第一軸編碼器２７與第二軸編碼器２８而分別求得第一與第二量測輪２５、２６的角度以及角速度，並藉由比對紙張在第一量測輪２５與第二量測輪２６位置處的移動速度而求得紙張的移動方向。Referring to the seventh figure, in another embodiment shown in the figure, the dynamic measuring device comprises a first measuring wheel 25 and a second measuring wheel 26, a first measuring wheel 25 and a second measuring wheel. 26 is connected to the first shaft encoder 27 and the second shaft encoder 28 via a set of transmission mechanisms 29, respectively, wherein the first measuring wheel 25 and the second measuring wheel 26 are respectively fixed on the paper feeding path 10. The left and right sides are in contact with the left and right sides of the paper in the paper feed path 10, and the first measuring wheel 25 and the second measuring wheel 26 will rotate with the paper as the paper passes through the paper feeding path 10. The angles and angular velocities of the first and second measuring wheels 25, 26 are respectively obtained by the first shaft encoder 27 and the second shaft encoder 28, and the first measuring wheel 25 and the second measuring wheel are respectively aligned by the paper. The moving speed of the position of the measuring wheel 26 is used to determine the moving direction of the paper.
再請參閱第八Ａ圖至第八Ｃ圖，如圖中所示，在正常的送紙過程中，第一量測輪２５與第二量測輪２６所量測到的紙張速度應保持相同，且以預定的送紙速度移動。若如第八Ｂ圖中所示，第一與第二量測輪２５、２６量測到的速度值相同但是均小於預定的送紙速度，則紙張可能已受到異常的阻力並發生卡紙的現象。相對的，若如第八Ｃ圖所示，第一與第二量測輪２５、２６所量測到的移動速度均未低於預定的送紙速度，但是兩惰輪量測到的速度具有速度差，則紙張並未順著送紙路徑１０前進，且可預期的將會撞上送紙路徑１０的邊緣並造成卡紙。因此當控制單元２４監測到紙張的移動方向或移動速度發生異常時，便控制取紙裝置２１與輸送裝置２２停止取紙與送紙，以避免紙張因卡紙而受損。Referring again to FIGS. 8A to 8C, as shown in the figure, the paper speed measured by the first measuring wheel 25 and the second measuring wheel 26 should remain the same during normal paper feeding. And move at a predetermined paper feed speed. If the speed values measured by the first and second measuring wheels 25, 26 are the same as shown in the eighth drawing but are less than the predetermined paper feeding speed, the paper may have been subjected to abnormal resistance and jammed. phenomenon. In contrast, as shown in FIG. C, the moving speeds measured by the first and second measuring wheels 25, 26 are not lower than the predetermined paper feeding speed, but the speeds measured by the two idlers have If the speed is poor, the paper does not advance along the paper feed path 10, and it is expected that it will hit the edge of the paper feed path 10 and cause a jam. Therefore, when the control unit 24 detects that the moving direction or the moving speed of the paper is abnormal, the paper picking device 21 and the conveying device 22 are controlled to stop the paper picking and paper feeding to prevent the paper from being damaged due to the paper jam.
由以上敘述可知，本發明藉著直接檢測紙張的移動速度與移動方向，並在紙張的移動速度或移動方向發生異常時立刻暫停取紙與送紙動作來避免紙張卡紙。因此與現有送紙機構相比較，可以更迅速準確的對紙張輸送狀況異常做出反應，減少紙張因卡紙而受損的現象。As apparent from the above description, the present invention avoids paper jam by directly detecting the moving speed and moving direction of the paper and immediately suspending the paper picking and paper feeding operations when an abnormality occurs in the moving speed or moving direction of the paper. Therefore, compared with the existing paper feeding mechanism, the paper conveying condition can be reacted more quickly and accurately, and the paper is damaged due to paper jam.
