The bottom of the guiding groove 233 may be, but not limited to, a vertical elongated hole shape, and the aperture thereof is slightly larger than the width of the insertion end 2312 of the paper stopper member 231. The guiding portion 2332 is connected to the straight portion 2331 and faces the pickup roller 21 The direction is inclined, and the aperture is larger than the aperture of the straight portion 2331 to provide a space in which the tip 2312 of the paper stopper member 231 moves.
再者，請再參閱第4A圖，導槽233之導引部2332係具有一第一傾斜面23321及與第一傾斜面23321相對應設置之一第二傾斜面23322，第一傾斜面23321及第二傾斜面23322係朝取紙滾輪21之方向傾斜，且第一傾斜面23321係鄰近取紙滾輪21。請再次參閱第2、4A-4E圖，擋紙機構23更具有一彈性元件234，其係鄰設於導槽233之直線部2331，可為但不限為由泡棉或是彈片所製成，於擋紙元件231之插梢2312設置於直線部2331時，彈性元件234將與插稍2312相抵觸，以經由插稍2312提供一彈性作用力至擋紙部2311。 Furthermore, referring to FIG. 4A, the guiding portion 2332 of the guiding groove 233 has a first inclined surface 23321 and a second inclined surface 23322 corresponding to the first inclined surface 23321, and the first inclined surface 23321 and The second inclined surface 23322 is inclined toward the direction of the pickup roller 21, and the first inclined surface 23321 is adjacent to the pickup roller 21. Referring to FIG. 2 and FIG. 4A-4E again, the paper stopper mechanism 23 further has an elastic member 234 disposed adjacent to the straight portion 2331 of the guide groove 233, which may be, but not limited to, made of foam or shrapnel. When the insertion end 2312 of the paper stopper member 231 is disposed on the straight portion 2331, the elastic member 234 will interfere with the insertion portion 2312 to provide an elastic force to the paper stopper portion 2311 via the insertion portion 2312.
以下請參閱第4A-4E圖，並配合第2圖及第3A、3B圖所示之結構來說明本案擋紙機構之作動方式。首先，如第4A圖所示，在待機狀態下，亦即取紙滾輪21進行取紙前，擋紙元件231之擋紙部2311係插設於容置槽271中，且接觸供紙盤24上堆疊的紙張P之前緣，以阻擋紙張P進入導紙路徑x，在此同時，擋紙元件231之插梢2312係容置於導槽233之直線部2331中，且擋紙元件231的受抵部2314係設置於凸部2323與軸套部2321之間，並與受抵部2314相抵觸。 Please refer to Figure 4A-4E below, and explain the operation of the paper stopper mechanism in this case in conjunction with the structure shown in Fig. 2 and Figs. 3A and 3B. First, as shown in FIG. 4A, in the standby state, that is, before the pickup roller 21 performs the paper picking, the paper stopper portion 2311 of the paper stopper member 231 is inserted into the accommodating groove 271 and contacts the paper feed tray 24 The leading edge of the stacked paper P is disposed to block the paper P from entering the paper guide path x, and at the same time, the insertion end 2312 of the paper stopper member 231 is accommodated in the straight portion 2331 of the guide groove 233, and the paper blocking member 231 is received. The abutting portion 2314 is disposed between the convex portion 2323 and the boss portion 2321 and is in contact with the abutting portion 2314.
請再參閱第4A圖，當紙張P放入供紙盤24時，會因擋紙元件231之擋紙作用，而停止在擋紙元件231之擋紙部2311前，此時擋紙元件231之插 梢2312會設置於導槽233之直線部2331中且與擋紙元件231之插稍2312相抵觸，即插梢2312會頂到彈性元件234，彈性元件234將施予插稍2312一朝紙張P方向之作用力，以將該作用力傳遞至擋紙部2311，而使紙張P稍微回彈，可有效防止紙張P放入供紙盤24的力量過大，而發生要進行取紙時，擋紙元件231之插梢2312卡在導槽233之直線部2331中而使得整個擋紙元件231無法抬起的情況發生。另外，在進行取紙前擋紙元件231之擋紙部2311亦會插設於導紙路徑X上之容置槽271中，因此，當紙張P放入供紙盤24中時，擋紙元件231上方以插梢2312作為支撐點，而下方則以擋紙部2311作為另一個支撐點，上下共有兩支點來支撐擋紙，使得擋紙元件231可以更確實的達到擋紙的功效。 Referring to FIG. 4A again, when the paper P is placed in the paper feed tray 24, it stops in front of the paper stopper portion 2311 of the paper stopper member 231 due to the paper blocking action of the paper stopper member 231, and at this time, the paper stopper member 231 Insert The tip 2312 is disposed in the straight portion 2331 of the guide groove 233 and is in contact with the insertion portion 2312 of the paper stopper member 231, that is, the insertion end 2312 is pushed to the elastic member 234, and the elastic member 234 is applied to the insertion portion 2312 toward the paper P. The force of the direction is such that the force is transmitted to the paper stopper 2311, and the paper P is slightly rebounded, so that the force of the paper P placed in the paper feed tray 24 can be effectively prevented from being excessively large, and the paper jam occurs when the paper is taken. The insertion of the tip 2312 of the member 231 in the straight portion 2331 of the guide groove 233 causes the entire paper stopper member 231 to be lifted. In addition, the paper stopper portion 2311 of the paper-receiving member 231 is also inserted into the accommodating groove 271 of the paper guide path X. Therefore, when the paper P is placed in the paper feed tray 24, the paper stopper member Above the 231, the insertion end 2312 is used as a support point, and the lower side takes the paper blocking portion 2311 as another support point, and two points are supported on the upper and lower sides to support the paper stop, so that the paper blocking member 231 can more reliably achieve the effect of blocking the paper.
請參閱第4B圖，當自動饋紙裝置2收到饋紙指令時，分紙滾輪22將受驅動裝置之驅動而轉動，同時，取紙臂25以分紙滾輪22之軸部221為轉軸，帶動取紙滾輪21往下轉動並接近供紙盤24，且藉由傳動齒輪組26之傳動，取紙滾輪21會因應分紙滾輪22之轉動而轉動，以接觸及饋送供紙盤24上之紙張P。 Referring to FIG. 4B, when the automatic paper feeding device 2 receives the paper feed command, the paper feed roller 22 is driven to rotate by the driving device, and the paper take-up arm 25 has the shaft portion 221 of the paper separation roller 22 as a rotating shaft. The take-up roller 21 is driven to rotate downward and approach the paper feed tray 24, and by the transmission of the transmission gear set 26, the pickup roller 21 is rotated in response to the rotation of the separation roller 22 to contact and feed the paper feed tray 24. Paper P.
當取紙滾輪21往下朝供紙盤24接近時，由於導引元件232之軸套部2321係套設在取紙滾輪21之軸部211上，因此在取紙滾輪21往下接近供紙盤24的過程中，取紙滾輪21會帶動軸套部2321下降並以軸套部2321為旋轉軸旋轉，且導引元件232之延伸臂2322的受頂部23221會接觸到自間隔壁201、202往內延伸之抵頂元件235，並以抵頂元件235為支點，使延伸臂2322及凸部2323抵頂擋紙元件231之受抵部2314並將擋紙元件231往上提，即擋紙元件231之受抵部2314受凸部2323以及凸部2323與受頂部23221之間的延伸臂2322的抵頂，而使擋紙元件231因槓桿原理往上抬起，進而帶動擋紙部2311上升而脫離容置槽271，至於，擋紙元 件231之插梢2312將脫離導槽233之直線部2331並由直線部2331移動至第一傾斜面23321。 When the paper take-up roller 21 approaches the paper feed tray 24 downward, since the sleeve portion 2321 of the guiding member 232 is sleeved on the shaft portion 211 of the paper take-up roller 21, the paper take-up roller 21 approaches the paper feed downward. During the process of the disk 24, the take-up roller 21 will drive the sleeve portion 2321 to descend and rotate with the sleeve portion 2321 as a rotating shaft, and the top portion 23221 of the extending arm 2322 of the guiding member 232 will contact the self-dividing walls 201, 202. The abutting member 235 extends inwardly, and the abutting member 235 is used as a fulcrum, so that the extending arm 2322 and the protruding portion 2323 abut against the receiving portion 2314 of the top paper blocking member 231 and lift the paper blocking member 231 upward, that is, the paper stopper The receiving portion 2314 of the element 231 is abutted by the protruding portion 2323 and the extending portion 2322 between the convex portion 2323 and the receiving portion 23221, so that the paper blocking member 231 is lifted up by the principle of the lever, thereby driving the paper stopping portion 2311 to rise. And out of the receiving groove 271, as for the paper blocking element The insertion end 2312 of the member 231 will be separated from the straight portion 2331 of the guide groove 233 and moved by the straight portion 2331 to the first inclined surface 23321.
請參閱第4C圖，當取紙滾輪21持續往下降，擋紙元件231的插梢2312將藉由第一傾斜面23321的引導使得擋紙元件231持續朝取紙滾輪21方向傾斜，如此一來，擋紙元件231即可遠離導紙路徑X，當取紙滾輪21碰到紙張P時，便會開始帶紙，讓最上層之紙張P通過擋紙部2311而傳送至導紙路徑X中。 Referring to FIG. 4C, when the pickup roller 21 continues to descend, the insertion end 2312 of the paper stopper member 231 will cause the paper stopper member 231 to continuously tilt toward the pickup roller 21 by the guidance of the first inclined surface 23321, thus The paper stopper member 231 can be moved away from the paper guide path X. When the pickup roller 21 hits the paper P, the paper feed is started, and the uppermost paper P is conveyed to the paper guide path X through the paper stopper portion 2311.
此時，因取紙滾輪21下降的幅度大，導引元件232之延伸臂2322的受頂部23221受蓋體20之抵頂元件235的支撐並以軸套部2321為旋轉軸而旋轉移動，將使導引元件232的凸部23623跨至抵頂元件235的另一側，可為但不限為由抵頂元件235的左側跨至右側，而擋紙元件231的受抵部則由凸部2323與軸套部2321之間跨設至凸部2323與阻擋部2324之間。 At this time, due to the large extent of the falling of the pickup roller 21, the top portion 23221 of the extension arm 2322 of the guiding member 232 is supported by the abutting member 235 of the cover 20 and is rotated by the sleeve portion 2321 as a rotation axis. The convex portion 23623 of the guiding member 232 is spanned to the other side of the abutting member 235, which may be, but is not limited to, the left side of the abutting member 235 to the right side, and the abutting portion of the paper blocking member 231 is formed by the convex portion. The gap between the 2323 and the boss portion 2321 is spanned between the convex portion 2323 and the blocking portion 2324.
請參閱第4D圖，當取紙滾輪21取紙完成後，取紙滾輪21將反向上旋回到原始位置，並連帶帶動導引元件232旋轉回到原始位置，此時若有供紙盤24中的紙張P偷跑，即紙張P往前移動且覆蓋於容置槽271的上方，紙張P會擋住容置槽271上方的開口，但因此時導引元件232之延伸臂2322並未與抵頂元件235連接，因此，導引元件232可以軸套部2321為旋轉軸旋轉，使得擋紙元件231之擋紙部2311不會強制插回容置槽271中，而不會使提前移動之紙張P有破裂的風險。 Referring to FIG. 4D, when the paper take-up roller 21 is finished, the paper take-up roller 21 will be reversely rotated back to the original position, and the belt guiding member 232 is rotated to return to the original position, and at this time, if there is a paper feed tray 24 The paper P is sneaked, that is, the paper P moves forward and covers the upper portion of the accommodating groove 271. The paper P blocks the opening above the accommodating groove 271, but the extension arm 2322 of the guiding member 232 does not come to the top. The element 235 is connected. Therefore, the guiding member 232 can rotate the sleeve portion 2321 as a rotating shaft, so that the paper stopping portion 2311 of the paper blocking member 231 is not forcibly inserted into the receiving groove 271, and the paper P that moves in advance is not caused. There is a risk of rupture.
請參閱第4E圖，當取紙滾輪21取紙完成後，取紙滾輪21將反向上旋而遠離供紙盤24以回到原始位置，並連帶帶動導引元件232旋轉回到原始位置使取紙滾輪21之軸部211藉由軸套部2321帶動導引元件231及擋紙元件231下降，而此時因擋紙元件231之受抵部2314係置於導引元件232之凸部2323與阻擋部2324之間，凸部2323會頂住擋紙元件231之受抵部 2314，且擋紙元件231之插梢2312將由第一傾斜面23321移動至第二傾斜面23322，再由第二傾斜面23322移動至直線部2331，因此擋紙元件231之擋紙部2311將可下降且精確定位插設於容置槽271中，當擋紙元件231之插梢2312持續下降至直線部2331的底部時，擋紙元件231之受抵部2314將由凸部2323與阻擋部2324之間跨回凸部2323與軸套部2321之間(如第4A圖所示)，使擋紙元件231可回歸擋紙位置，在下一個取紙動作開始前，阻擋供紙盤24上堆疊之紙張P進入導紙路徑X，且同時具有整理紙張前緣的功能。 Referring to FIG. 4E, when the paper take-up roller 21 is taken out, the pickup roller 21 will be reversely rotated upside away from the paper feed tray 24 to return to the original position, and the belt guiding member 232 is rotated to return to the original position. The shaft portion 211 of the paper roller 21 is driven by the sleeve portion 2321 to lower the guiding member 231 and the paper stopper member 231. At this time, the abutting portion 2314 of the paper stopper member 231 is placed on the convex portion 2323 of the guiding member 232. Between the blocking portions 2324, the convex portion 2323 will abut against the abutment portion of the paper stopper member 231. 2314, and the insertion end 2312 of the paper stopper member 231 is moved from the first inclined surface 23321 to the second inclined surface 23322, and then moved to the straight portion 2331 by the second inclined surface 23322, so the paper blocking portion 2311 of the paper blocking member 231 will be The lowering and the precise positioning are inserted into the accommodating groove 271. When the insertion end 2312 of the paper blocking member 231 continues to descend to the bottom of the straight portion 2331, the abutting portion 2314 of the paper blocking member 231 will be replaced by the convex portion 2323 and the blocking portion 2324. Between the inter-transverse convex portion 2323 and the sleeve portion 2321 (as shown in FIG. 4A), the paper stopper member 231 can be returned to the paper stop position, and the paper stacked on the paper feed tray 24 is blocked before the next paper take-up operation starts. P enters the paper guide path X and at the same time has the function of sorting the leading edge of the paper.
綜上所述，本案之具有導引元件之擋紙機構及其所適用之自動饋紙裝置，其主要包含導引元件、擋紙元件以及導槽，當取紙滾輪朝供紙盤接近時，透過軸套部與取紙滾輪連動之導引元件會帶動擋紙元件之擋紙部上升而脫離容置槽，且帶動擋紙元件之插梢於導槽中移動，使受抵部由凸部與軸套部之間跨至凸部與阻擋部之間，以使一紙張通過擋紙部而傳送至一導紙路徑中，使本案可解決擋紙不夠確實、擋紙支撐點無彈性，取紙時容易造成擋紙元件卡死，無法順利解除擋紙，以及取紙完成後，擋紙元件無法正確回到擋紙位置等問題。 In summary, the paper stopper mechanism having the guiding member and the automatic paper feeding device applied thereto mainly include a guiding member, a paper blocking member and a guide groove, and when the pickup roller approaches the paper feeding tray, The guiding element that is coupled to the paper take-up roller through the sleeve portion drives the paper stopping portion of the paper blocking member to rise out of the receiving groove, and drives the insertion end of the paper blocking member to move in the guiding groove, so that the receiving portion is convex Between the protruding portion and the blocking portion, the paper is conveyed to a paper guiding path through the paper blocking portion, so that the paper can solve the problem that the paper blocking is not accurate and the paper stopping support point is inelastic. When the paper is jammed, the paper stopper element is likely to be stuck, the paper stopper cannot be smoothly released, and the paper stopper member cannot be correctly returned to the paper stopper position after the paper is taken out.
本案得由熟知此技術之人士任施匠思而為諸般修飾，然皆不脫如附申請專利範圍所欲保護者。 This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application.
