The specific embodiment
According to the disclosed paper delivery mechanism of the utility model, be assemblied in the media article logger, in order to transmit the paper of a predetermined number.Its main purpose is to provide the more fast speed paper sheet delivery pattern of moving.
Refer now to the basic framework that Fig. 2 illustrates paper delivery mechanism of the present utility model.This paper delivery mechanism has a paper feed path, according to the sense of motion of paper 200, disposes pickup roller 10, relaying roller 20, paper-feeding roller 30 in regular turn and goes out paper roller 80 on the paper feed path.One auxiliary pickup roller 11 is installed in the corresponding position of pickup roller 10, and a predetermined distance is apart arranged and can cooperate pickup roller 10 to come the paper 200 of clamping different-thickness.Alternative routing roller 21 is installed in the corresponding position of relaying roller 20, and a predetermined distance is apart arranged and can cooperate relaying roller 20 to come the paper 200 of clamping different-thickness.Auxiliary paper-feeding roller 31 is installed in the corresponding position of paper-feeding roller 30, and a predetermined distance is apart arranged and can cooperate paper-feeding roller 30 to come the paper 200 of clamping different-thickness.In the same manner, assist out paper roller 81 to be installed in out the corresponding position of paper roller 80, and a predetermined distance is apart arranged and can cooperate the paper 200 of paper roller 80 with the clamping different-thickness.
CD-ROM drive motor 70 is propulsions source of whole mechanism, for the required propulsive effort of mechanism's work, in fact is made of first power gear 71, second power gear 72 and the 3rd power gear 73.Certainly showed with three power gear in the icon, and non-limiting need can transfer a driving force to other assembly by three gears.First clutch is coupled to CD-ROM drive motor 70, and is assemblied on the paper feed path, with the mode of operation of control pickup roller 10.First clutch is actually by the first clutch body of rod 40, first clutch gear 41 and the first clutch idle gear 42 to be formed, the first clutch body of rod 40 is arranged in the media article logger in the mode that can swing, and stretch out the paper feed path, an elastic component (as torsion spring etc.) is selectively assembled in the other first clutch body of rod 40 and the junction of media article logger, produces swing to make paper 200 can suppress the first clutch body of rod 40 smoothly.First clutch gear 41 is assemblied in a side of the first clutch body of rod 40, and the first clutch idle gear 42 is coupled to first clutch gear, and affects pickup roller 10 by belt 43.Certainly be not to need to drive pickup roller 10 by belt 43, also the mode that can directly be coupled to each other is come transmission of drive force, only illustrates the mode of belt 43 among the figure.Second clutch includes the second clutch body of rod 50, be equipped in the media article logger in the mode that can swing, first idle gear 51 is coupled to CD-ROM drive motor 70, wherein between the second clutch body of rod 50 and first idle gear 51 friction force is arranged, when the hand of rotation of first idle gear 51 changed, the second clutch body of rod 50 also can and then rotate.The second clutch right gear 54 is installed in an end of the second clutch body of rod 50, and is coupled to first idle gear 51.The second clutch left gear 52 is provided with the other end of the second clutch body of rod 50, and is coupled to first idle gear 51.Sensor 60 is arranged at the end in paper feed path, in order to the mode of operation of control second clutch.
By Fig. 2 and mentioned above, can clearly recognize the roughly composition of paper delivery mechanism of the present utility model, as for continuous action relation between each assembly and real-world operation state, will describe in detail in hereinafter being aided with accompanying drawing.
Please refer to Fig. 3, at first CD-ROM drive motor 70 provides propulsive effort, drive pickup roller 10 by first idle gear 51, first clutch gear 41 and the first clutch idle gear 42, and cooperate auxiliary pickup roller 11 to obtain paper 200, will touch the first clutch body of rod 40 until paper 200.Then as shown in Figure 4, the leading edge of paper 200 will touch the first clutch body of rod 40 and continue to advance, the first clutch body of rod 40 is pressed down by the compacting of paper 200 therefore and rotates a predetermined angle, make first clutch gear 41 leave the first clutch idle gear 42, therefore what pickup roller 10 will stop paper 200 gets the paper operation, advancing of paper 200 is to be responsible for by relaying roller 20 and alternative routing roller 21 at this moment, the running of relaying roller 20 is by first idle gear 51 in addition, the second clutch left gear 52 and second idle gear 53 transmit the propulsive effort that CD-ROM drive motor 70 is provided, and relaying roller 20 is identical with the hand of rotation of paper-feeding roller 30.Next ask for an interview Fig. 5, when paper 200 leading edges are detected by sensor 60, will transmit electronic information and come controlling and driving motor 70 to change hand of rotation, and control the angle that 50 rotations one of the second clutch body of rod are scheduled to.To make the second clutch left gear 52 remove the meshing relation with second idle gear 53 after the rotation of the second clutch body of rod 50, and be coupled directly to relaying roller 20 by the second clutch right gear 54, and continue paper 200 is given forward, but because of relaying roller 20 is opposite with the sense of motion of paper-feeding roller 30, so the leading edge of paper 200 will align before paper-feeding roller 30.
As shown in Figure 6, after the leading edge of paper 200 aligns, CD-ROM drive motor 70 changes hand of rotation once more, paper 200 transmission is left with going out paper roller 80 by paper-feeding roller 30, and can be read the data on the paper or carry out other action by mechanisms such as image capture units 90.At last as shown in Figure 7, when the trailing edge of paper 200 leaves the first clutch body of rod 40, the first clutch body of rod 40 will be returned to initial position, and interlock first clutch gear 41 falls with the first clutch idle gear 42 and is meshing with each other, and the propulsive effort that provided from CD-ROM drive motor 70 can be provided, and drive pickup roller 10 and obtain next paper 200.
By above description, can recognize clearly that paper delivery mechanism of the present utility model has following advantage at least:
(1) high speed paper feed mode of operation: after must waiting for that compared to prior art paper withdraws from paper advance mechanism fully, another paper of gripping once again, paper delivery mechanism provided by the utility model, trailing edge at paper leaves the first clutch body of rod, can carry out the operation that enters of next paper, and significantly reduce the haulage time of paper in the unit time, and carry out high-revolving paper feed mode of operation.
(2) simple structure: the disclosed paper delivery mechanism simple structure assembling of the utility model only can be finished by simple die clutch construction easily, and the time of production and assembly shortens dramatically, and is beneficial to the manufacturing.Moreover assemble easily because of its simple structure, nature can greatly reduce relevant cost, makes product more competitive.
The above only is this later-model preferred embodiment, is not to be used for limiting practical range of the present utility model; All equalizations of being done according to this specification sheets and accompanying drawing content change and modify, and all are included in the claim of the present utility model.
