The specific embodiment
Please refer to Fig. 3, it is for the lateral plan of autoamtic paper feeding system of the present invention.Autoamtic paper feeding system 20 includes a shell 22, one storage paper box 24 is fixed in and is used for bearing paper 21 in the shell 22, it includes a front end moving up and down, one paper-feeding passage 28, one paper extraction unit 30 is located at the top of storage paper box 24, one paper separating device, 32, one control setups 36, and an actuating device 38 (not shown).Storage paper box 24 includes a front end, and paper-feeding passage 28 is located at the outside of storage paper box 24 front ends.Paper separating device 32 includes a comber 33 and a separation friction lining 34, is located at the both sides up and down of paper-feeding passage 28 respectively.
Please refer to Fig. 4, it is for the actuating device functional block diagram of automatic paper feeder of the present invention.Actuating device 38 includes a motor 40 and a driving device 42, is used for driving simultaneously paper extraction unit 30, paper separating device 32 and control setup 36.Autoamtic paper feeding system 20 includes a sensing device 46 in addition, its position is located in the shell 22 and is positioned at the rear side of paper separating device 32, be used for the paper of sensing by paper separating device 32, and a control circuit 44, be used for deciding the hand of rotation of motor 40 according to the output of sensing device 46.
Paper extraction unit 30 includes a roller (roller) 31 and is fixed in the shell 22 in rotating mode.When the front end controlled device 36 of storage paper box 24 upwards lifted, the paper 21 in the storage paper box 24 can touch the roller 31 of paper extraction unit 30 and be sent to paper-feeding passage 28.Control setup 36 is located at paper-feeding passage 28 belows, and the front end and the separation friction lining 34 that are used for will storing up simultaneously paper box 24 lift or put down.Control setup 36 includes one first gear 48 and one second gear 50, is located at paper-feeding passage below 28 in intermeshing mode, and one first rocking bar 52 and one second rocking bar 54.One end of first rocking bar is fixed on first gear 48, the other end is positioned at the downside of storage paper box 24 front ends, be used for lifting or falling the front end of storage paper box 24, one end of second rocking bar 54 is fixed in second gear 50, the other end is positioned at the downside of separation friction lining 34, is used for lifting or falls separation friction lining 34.
Please refer to Fig. 5.Lateral plan when it carries out the paper feeding action for autoamtic paper feeding system of the present invention.When beginning to carry out the paper feeding action, motor 40 beginnings of the control circuit 44 meeting driver 38 of autoamtic paper feeding system 20 are turned round towards a first direction.When motor 40 during towards the rotation of this first direction, front end and separation friction lining 34 that driving device 42 can driving control devices 36 will store up paper box 24 simultaneously upwards lift.When the front end controlled device 36 of storage paper box 24 upwards lifts, paper 21 in the storage paper box 24 can touch the roller 31 of paper extraction unit 30, and actuating device 38 (not shown) is driving rolls 31 and make the paper 21 in the storage paper box 24 be moved into paper-feeding passage 28 forward simultaneously.When two pieces of paper enter one of 34 of comber 33 and separation friction linings and are abutted against, the paper that is positioned at comber 33 sides can move forward by the drive of comber 33, and the paper that is positioned at separation friction lining 34 sides can be held by separation friction lining 34 and can't advance.This be because the comber 33 of paper separating device 32, and paper and separation friction lining 34 and paper between friction force all greater than paper friction force each other, therefore 33 of combers can be taken away the paper that is contacted smoothly, and unnecessary paper is stayed on the separation friction lining 34.
Please refer to Fig. 6.It is the top view of the torque force limiting device 56 of autoamtic paper feeding system of the present invention.In autoamtic paper feeding system 20 paper feeding processes, driving device 42 can drive paper extraction unit 30, paper separating device 32 and control setup 36 constantly.Yet, because first rocking bar 52 of control setup 36 and second rocking bar 54 should just shut down at its first dead center of arrival (top dead point), therefore between first rocking bar 52 and first gear 48, be provided with a torque force limiting device (torgue limiter) 56 in addition, be used for limiting the torsion that is sent to first rocking bar 52 and second rocking bar 54.When the paper 21 when first rocking bar 52 makes storage paper box 24 because of rising in touched the roller 31 of paper extraction unit, torque force limiting device 56 can make first rocking bar 52 stop to rise but first gear 48 still can continue to drive running by driving device 42.Same, also be provided with a torque force limiting device 56 between second rocking bar 54 and second gear 50, when second rocking bar 54 made separation friction lining 34 upwards touch comber 33 because of rising, torque force limiting device 56 can make second rocking bar 54 stop to rise but second gear 50 still can continue to drive running by driving device 42.Please refer to Fig. 7, torque force limiting device 56 by spring plate washer 60, spring 64 and friction lining (for example: wool felt) form for 62.Can utilize the friction size of the elastic force of spring 64 and Friction disk 62 to decide the torque magnitude of torque force limiting device 56.
When sensing device 46 senses paper 21 front ends by paper separating device 32, control circuit 44 can make motor 40 rotate with drive transmission 42 towards the second direction opposite with above-mentioned first direction, drive control setup 36 and the front end of storage paper box 24 and separation friction lining 34 are put down simultaneously by driving device 42 again, return to state as shown in Figure 3.At this moment, the comber 33 of paper separating device 32 promptly can't drive the paper 21 that enters paper-feeding passage 28 forward.When sensing device 46 sensed paper 21 and leaves autoamtic paper feeding system 20 fully, control circuit 44 can make motor 40 rotate with drive transmission 42 towards first direction again, continued to repeat paper feeding process as hereinbefore.Office work machine major part all can design the rear that a correcting (de-skew) device is located at feeding system 20 at present, and the paper of being sent to prevent is distorted.Therefore, when another advantage of the present invention entered guide device for leave feeding system 20 when top of form, comber 33 can avoid the front and back ends of paper to bear pullling of producing because of stressed inequality with separating of separation friction lining 34.
Compare with existing feeding system, feeding system 20 of the present invention has paper extraction unit 30 and paper separating device 32 simultaneously, can effectively reduce multiple paper feeding or paperboard caused can't the paper feed situation.Autoamtic paper feeding system 20 of the present invention utilizes a control setup 36 to control the lifting of storage paper box 24 and separation friction lining 34 simultaneously.Wherein control setup 36 utilizes the just commentaries on classics of motor 40, counter-rotating to decide direction of action.Therefore one group of actuating device 38 of 20 needs of the whole autoamtic paper feeding system of the present invention just can drive paper extraction unit 30, paper separating device 32 simultaneously with control setup 36, finishes whole paper feeding process, can reduce the quantity of the required element of system.In addition, because the separation friction lining 34 in the paper separating device 32 only can contact with comber 33 in the process of carrying out paper feeding, therefore can avoid paper when carrying out the correcting process, to be pullled.
Above-described only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the covering scope of patent of the present invention.
