Description of the Invention: [Technical Field] The present invention relates to a paper separating device for an automatic paper feeder, and more particularly to an automatic paper feeder separating device having an energy storage effect. [Prior Art] The automatic paper feed cassette can be (4) in image input/rounding devices such as scanners, multifunction printers, printers, and even printers. In order to feed the paper one by one, a paper separation device must be provided in the automatic paper feeder so that multiple sheets of paper can be prevented from being fed at the same time. 1 to 3 show schematic views of the operation of a conventional paper separating device. As shown in Figures 1 to 3, the conventional secret holder is a white paper < paper cutter device comprising a paper separation roller i 1 , a friction wheel 120 and a torque limiter 13 (). The separation roller ιι is mounted on the shaft 112. The rotating shaft 112 may be a rotating shaft of the motor. The friction wheel 120 is mounted on a rotating shaft 122. The shaft 122 is the shaft of the other motor. The torque limiter 130 is coupled to the friction wheel 12A and the rotating shaft to provide a torque that limits the rotation of the friction wheel 120. As shown in Fig. 1 and 7F, in the case where the paper separation function has not been started yet, the separation roller "0 rotates clockwise and drives the friction wheel 12 to rotate, so as to feed the sheets S1 and S2, and the paper is not fed. The situation of multiple feeds expected. In order to solve this problem, as shown in FIG. 2, the rotating shaft 122 drives the friction wheel 12 to continuously rotate in the clockwise direction through the torque limiter 130, so as to push the paper §2 out of the friction wheel m and the minute under the condition of multiple sheets feeding. The passage between the paper rollers 110 to meet the requirements of the paper separation. As shown in FIG. 3, when the paper 82 is left, the rotating shaft 112 drives the paper separation! 2895〇8 The roller 11 旋转 rotates clockwise so that the paper S2 enters the passage, and the paper S2 and the friction wheel 120 are held together. Force n. ^ hand ^ knife tribute friction wheel 120 along the reverse: the direction of the needle 'while fortunately' 22 driving torque limit n 13 〇 shun: needle rotation. But because the paper S2 drives the friction wheel i2G to reverse ten directions The torque of the rotation is greater than the torque limit. The torque of the friction wheel 120 is rotated clockwise, so the seat ± M thick wiper 12〇 will be rotated counterclockwise by the paper S2. Therefore, the paper is distributed. The device needs to have two power sources and a torque limiter, and the frictional friction between the friction wheel, the torsion limiter and the rotating shaft causes the manufacture to be the same as that of the same and easy to wear and affect the subsequent separation. [Invention] The automatic paper feeder, together with the energy storage type paper-storing energy storage component that can be stored and can effectively reduce the energy storage of the paper feeder, can be separated by the friction wheel in the paper separation roller. Being driven by a friction wheel Therefore, an object of the present invention is to provide an energy storage type separation device in which only one energy storage element storing energy is used, so that the operation of the paper separation is more reliable and the cost of the paper separation device is reduced and the roller is reduced. In order to achieve the above object, the present invention provides an automatic paper separating device for feeding a first paper and a first paper sheet separately. The automatic paper feed tray includes a paper separation roller. A friction wheel, a shaft and a paper roller are driven to rotate by a driving device. The motor is driven to rotate. The shaft passes through the friction wheel and is rotated relative to the stationary state. The energy storage element is connected to the shaft friction wheel and is moved to store one. The energy friction wheel has a first 1 : wire 89508 state and a second forward rotation state. In the first forward rotation state of the friction wheel, the friction wheel train is rotated by the paper separation roller to feed the first paper Feeding or feeding the first paper and the second paper at the same time, the friction wheel also drives the energy storage element to store the energy of the energy storage element. In the reverse state of the friction wheel, the energy dissipating component releases energy and makes the friction wheel Turning to push the second paper away from the friction wheel and the separation roller in the second forward rotation state of the friction wheel, and the separation roller drives the second paper/paper to make the second paper/first-, sheet The friction wheel is rotated to store energy in the energy storage element.
At旦藉由本毛明之上述分紙裝置，利用儲能裝置來儲存 :里，只要在通道間存在有兩張紙張的時候，摩擦輪即 會因儲能裝置之釋放能量而反轉，因此可將摩擦輪側之 β張紙張退出通道，避免多張饋紙的狀態。值得注意的 :，储能元件本身可以具有離合器或配設有一離合器， 以在儲存滿能量時，使摩擦輪能持續轉動。 【實施方式】 % 動作L4圖至7顯示依據本發明較佳實施例之分紙裝置之 之儲处―、ν如圖4至7所7^ ’本實施例之自動送紙器 之儲能式分紙裝置传用 張81疊接之一第二、：：：—第-紙張81以及與第-紙 ^ M At. 、、 x 2依序分開饋送。自動送紙器 二二:；置包含一分紙滾輪10、-摩擦輪-、- 之轉軸二Γ:元件40。分紙滾輪10受-驅動裝置12 旋轉，亦可被第可被分紙滾輪10驅動 30穿過摩擦輪2二 張S2帶動旋轉。軸 並相對於轉動中之摩擦輪20呈靜止 8 128950s 能二。儲能元件40可以是一蜗型彈簧或一扭轉彈簧。儲 ^疋件40連接軸3〇與摩擦輪2〇，用以被摩擦輪 動以儲存一能量。 驅 。 為了於初始設定時使儲能元件40儲存有一些能量， 可=對儲能元件40施以一預壓以預先儲存一定的能量。 =侍〉主意的是，當儲能元件4〇儲滿最大能量時，儲能元 1 40就不再儲存能量，但是不影響摩擦輪之轉動， ，、中可利用類似單向離合器等機構來達成此功能。 摩擦輪20具有一第一正轉狀態、一反轉狀態及 -正轉狀態。於摩擦輪20之第一正轉狀態下，如 二==向旋轉的分紙滾輪10帶動摩擦輪20朝逆 :第十=轉，以便將第一紙張S1饋入或將第一紙張以 ▲張S2同時饋入’此時’摩擦輪20亦驅動儲能 疋件40以使儲能元件4〇儲存能量。 於摩擦輪2 0之反鏟壯能τ , 茫S1 *。圖5所示，也就是紙 又 ” S2同時進入摩擦輪20與分紙爭鈐 道時，由於紙張suS2之間= =10之間的通 與摩擦輪20之間的摩捧力 1 紙張S2 以將摩擦…順時二元件4〇釋放能量 推離摩擦輪20與分紙滾輪簡第二紙張Μ “示的狀態。在饋紙過程中之:二道 =，雨、首摩擦輪2〇可能會間歇性地正轉或 反轉猎以在通道60之間維持單一 要有兩張紙張進入通道，儲能元件二換：：說’只 摩擦輪反轉，以將其中一張紙張推出通曰道中放月b里來·駆動 1289508 • 於摩擦輪20之第二正轉狀態下，如圖6與7所示， 分紙滾輪ίο驅動第二紙張S2/第一紙張si，使第二紙 S2/第-紙張S1帶動摩擦輪2〇旋轉來使儲能元件利餘 存能量。 此外，自動送紙器之健能式分紙裝置可以更包含链 .如彈簧或是一液壓/油麼裝置之-施力機構50,用以❹ .紙滾輪10與摩擦輪20推靠在一起。或者，可以利用分 紙滚輪1G自身的重量使分紙滾輪1。抵靠在摩擦輪20 #上。如此的設置可以使本裝置適用於不同厚度的紙張， 並可以對磨損的分紙滾輪或摩擦輪做即時補償。 藉由本發明之上述分紙裝置，可以不需要使用扭力 限制器’而是利用儲能元件達到有效降低成本、縮小體 積之優點。由於只有單一動力源，因此組裝上可以較為 簡化。由於摩擦輪與進紙滾輪及摩擦輪與紙張之間都是 處於滾動摩擦狀態，所以摩擦輪的磨損可以有效被降低， 藉以延長摩擦輪之使用壽命。 φ 在較佳實施例之詳細說明中所提出之具體實施例僅 •用以方便說明本發明之技術内容，而非將本發明狹義地 限制於上述實施例，在不超出本發明之精神及以下申請 專利範圍之情況，所做之種種變化實施，皆屬於本發明 之範圍。At the above-mentioned paper separation device of Ben Maoming, the energy storage device is used for storage: in the case where there are two sheets of paper between the channels, the friction wheel is reversed due to the energy released by the energy storage device, so The β sheets of paper on the friction wheel side exit the passage to avoid the state of multiple sheets. It is worth noting that the energy storage element itself may have a clutch or be equipped with a clutch to enable the friction wheel to continue to rotate when full energy is stored. [Embodiment] % actions L4 to 7 show the storage of the paper separation device according to the preferred embodiment of the present invention, ν, as shown in Figs. 4 to 7, the energy storage type of the automatic paper feeder of the present embodiment. The paper device transmits one of the sheets 81, a second, a:::-the first paper 81 and is fed separately from the first papers M At., x 2 in sequence. Automatic paper feeder 22:; includes a paper roller 10, - friction wheel -, - shaft 2: element 40. The separation roller 10 is rotated by the driving device 12, and can also be driven by the separation roller 10 to be rotated by the two S2 rollers. The shaft is stationary with respect to the rotating friction wheel 20 8 128950s. The energy storage element 40 can be a scroll spring or a torsion spring. The reservoir member 40 is coupled to the shaft 3〇 and the friction wheel 2〇 for being frictionally rotated to store an energy. Drive. In order to store some energy in the energy storage element 40 during the initial setting, a preload may be applied to the energy storage element 40 to pre-store a certain amount of energy. = The idea is that when the energy storage element 4 〇 is filled with the maximum energy, the energy storage element 1 40 will no longer store energy, but does not affect the rotation of the friction wheel, and may use a mechanism such as a one-way clutch. Achieve this feature. The friction wheel 20 has a first forward rotation state, a reverse rotation state, and a forward rotation state. In the first forward rotation state of the friction wheel 20, if the two == to the rotating paper separation roller 10, the friction wheel 20 is driven to the reverse: tenth=turn, so that the first paper S1 is fed or the first paper is ▲ The S2 simultaneously feeds the 'this time' friction wheel 20 also drives the energy storage element 40 to store energy in the energy storage element 4 . The anti-shovel τ of the friction wheel 20, 茫S1*. As shown in Fig. 5, when the paper "S2" enters the friction wheel 20 and the paper-discriminating track at the same time, since the paper between the suS2 ==10 and the frictional force between the friction wheel 20, the paper S2 is The friction...the second component 4 〇 release energy is pushed away from the friction wheel 20 and the separation roller is the second paper Μ "showing state. In the paper feeding process: two lanes =, rain, first friction wheel 2 〇 may intermittently forward or reverse hunting to maintain a single between the channels 60 to have two paper into the channel, the energy storage component two :: Say 'only friction wheel reversal, to push one of the papers out of the squatting lane to the moon b · sway 1289508 • In the second forward rotation state of the friction wheel 20, as shown in Figures 6 and 7, The paper roller ίο drives the second paper S2/first paper si to cause the second paper S2/the first paper S1 to rotate the friction wheel 2 to cause the energy storage element to retain energy. In addition, the manual paper separator of the automatic paper feeder may further include a chain, such as a spring or a hydraulic/oil device-applying mechanism 50, for pushing the paper roller 10 and the friction wheel 20 together. Alternatively, the separation roller 1 can be made by the weight of the separation roller 1G itself. Abut against the friction wheel 20 #. This arrangement allows the unit to be used with different thicknesses of paper and provides instant compensation for worn paper separation rollers or friction wheels. According to the above-described paper separating device of the present invention, it is possible to achieve the advantages of effectively reducing the cost and reducing the volume by using the energy storage element without using the torque limiter. Since there is only a single power source, assembly can be simplified. Since the friction wheel and the paper feed roller and the friction wheel and the paper are in a rolling friction state, the friction wheel wear can be effectively reduced, thereby prolonging the service life of the friction wheel. The specific embodiments of the present invention are described in the detailed description of the preferred embodiments, and are not intended to limit the scope of the present invention to the above embodiments, without departing from the spirit and scope of the invention. The scope of the patent application and the various changes made are within the scope of the invention.
