請一併參閱圖2,其是本發明第一實施例的使用分紙機構的自動饋紙電子裝置的示意圖;如圖所示,自動饋紙電子裝置2包括殼體21,設置在殼體21內的送紙機構22、出紙機構23以及分紙機構1,其中,分紙機構1位於送紙機構22與出紙機構23間。分紙機構1的第一預分紙組件11靠近送紙機構22,第一預分紙組件11的支撐架111固定在殼體21的內表面。送紙機構22及出紙機構23與目前市面的自動饋紙電子裝置的送紙機構及出紙機構相同,於此不再細說其結構。Please refer to FIG. 2 together, which is a schematic diagram of an automatic paper-feeding electronic device using a paper separation mechanism according to a first embodiment of the present invention. As shown in the figure, the automatic paper-feeding electronic device 2 includes a casing 21 and is disposed on the casing 21 The paper feeding mechanism 22, the paper discharging mechanism 23, and the paper separating mechanism 1 are located therein. The paper separating mechanism 1 is located between the paper feeding mechanism 22 and the paper discharging mechanism 23. The first pre-separation assembly 11 of the separation mechanism 1 is close to the paper feeding mechanism 22, and the support frame 111 of the first pre-separation assembly 11 is fixed on the inner surface of the casing 21. The paper feeding mechanism 22 and the paper discharging mechanism 23 are the same as the paper feeding mechanism and the paper discharging mechanism of the automatic paper feeding electronic device currently on the market, and their structures are not described in detail here.
本實施例的自動饋紙電子裝置2在使用時,層疊的紙張送入送紙機構22,多個輸送輪221帶動層疊的紙張往分紙機構1移動。請一併參閱圖3a及圖3b,其是本發明第一實施例的分紙機構的使用狀態圖;如圖所示,於此先將層疊的紙張分為上部紙張層31及下部紙張層32,以便於下述說明,下部紙張層32是指通過第一預分紙組件11的紙張層。層疊的紙張通過第一預分紙組件11時,每一個可撓墊片112的預分紙端部1121會與層疊的紙張接觸。預分紙端部1121具有背離分紙輥筒組件10的接觸表面1121a,接觸表面1121a接觸層疊的紙張,並與上部紙張層31間產生摩擦力F f,同時上部紙張層31有推動預分紙端部1121的推動力F d以及上部紙張層31的多個紙張間具有紙張摩擦力F f1,當F d+ F f1<F f時,可撓墊片112的預分紙端部1121可阻擋上部紙張層31。隨著送紙機構22持續帶動下部紙張層32往分紙輥筒組件10移動,下部紙張層32因可撓墊片112對其所產生的摩擦力F f遠小於送紙機構22對其的推力F s,使得下部紙張層32與上部紙張層31分離,並往分紙輥筒組件10移動。由上述可知,當層疊的紙張通過第一預分紙組件11時,第一預分紙組件11可阻擋大部份的紙張,使進入分紙輥筒組件10進行分紙的紙張數量大幅減少,達到預分紙的作用。 When the automatic paper feeding electronic device 2 of this embodiment is in use, the stacked paper is fed into the paper feeding mechanism 22, and the plurality of conveying wheels 221 drive the stacked paper to move to the paper separating mechanism 1. Please refer to FIG. 3a and FIG. 3b together, which are diagrams of the use state of the paper separating mechanism according to the first embodiment of the present invention; as shown in the figure, the laminated paper is first divided into an upper paper layer 31 and a lower paper layer 32. In order to facilitate the following description, the lower paper layer 32 refers to a paper layer passing through the first pre-separation module 11. When the stacked paper passes through the first pre-separation module 11, the pre-separation end portion 1121 of each flexible pad 112 is in contact with the stacked paper. The pre-separation end portion 1121 has a contact surface 1121a facing away from the separation roller assembly 10. The contact surface 1121a contacts the laminated paper and generates a friction force F f with the upper paper layer 31. At the same time, the upper paper layer 31 promotes the pre-separation. The pushing force F d of the end portion 1121 and the paper friction force F f1 between the plurality of sheets of the upper paper layer 31. When F d + F f1 <F f , the pre-splitting end portion 1121 of the flexible pad 112 can block Upper paper layer 31. As the paper feeding mechanism 22 continuously drives the lower paper layer 32 to move toward the separation roller assembly 10, the friction force F f generated by the flexible paper 112 on the lower paper layer 32 is much smaller than the thrust of the paper feeding mechanism 22 on it. F s causes the lower paper layer 32 to be separated from the upper paper layer 31 and moves toward the separation roller assembly 10. It can be known from the above that when the stacked paper passes the first pre-separation assembly 11, the first pre-separation assembly 11 can block most of the paper, and the number of papers entering the separation roller assembly 10 for separation is greatly reduced. To achieve the role of pre-separation.
在下部紙張層32傳送至分紙輥筒組件10前,也就是紙張未進入分紙輥筒101與延遲輥筒102間時,分紙輥筒101與延遲輥筒102接觸,分紙輥筒101轉動並帶動延遲輥筒102轉動。下部紙張層32傳送至分紙輥筒組件10後,分別接觸分紙輥筒101及延遲輥筒102,其中,延遲輥筒102的表面阻擋下部紙張層32中的大部份紙張32a,同時分紙輥筒101帶動下部紙張層32中位於底層的部份紙張32b進入分紙輥筒101與延遲輥筒102間,延遲輥筒102停止轉動並提供向下壓力,對進入分紙輥筒101與延遲輥筒102間的部份紙張32b進行分紙,讓最底層的紙張32c通過分紙輥筒101與延遲輥筒102間,通過的紙張從出紙機構23輸出。Before the lower paper layer 32 is conveyed to the separation roller assembly 10, that is, when the paper does not enter between the separation roller 101 and the retard roller 102, the separation roller 101 contacts the retard roller 102, and the separation roller 101 Rotate and drive the retard roller 102 to rotate. After the lower paper layer 32 is conveyed to the separation roller assembly 10, it contacts the separation roller 101 and the retard roller 102, respectively. Among them, the surface of the retard roller 102 blocks most of the paper 32a in the lower paper layer 32, and simultaneously The paper roller 101 drives a part of the paper 32b at the bottom of the lower paper layer 32 into the separation roller 101 and the delay roller 102. The delay roller 102 stops rotating and provides downward pressure. Part of the paper 32b between the retard rollers 102 is separated, and the bottom-most paper 32c passes between the separation roller 101 and the retard roller 102, and the passed paper is output from the paper discharge mechanism 23.
