The position that clips conveying road 2 and conveying roller 3 running contacies at the upper face side (opposite side) of carrying road 2 is setting separate roller 5.The rotating shaft 5a of separate roller 5 is installed near the swing front end of clamp arm 6 by bearing 6a with rotating freely.Center of oscillation at clamp arm 6 is connecting axle 6c by bearing 6b.The two ends of axle 6c are fixed on the base component 10.In addition, establishing spring 7 at the base end part of clamp arm 6 opening between itself and the base component 10, giving the elastic force of the direction of arrow in Fig. 1 frequently to clamp arm 6, separate roller 5 is urged on conveying roller 3 thus.
On a side belt pulley 11, and be installed in the toothed belt 15 of the ring-type of reeling between the belt pulley 4c on the rotating shaft 4a of motor 4.This belt pulley 11, belt pulley 4c and toothed belt 15 play a part second transmission mechanism of the present invention.The number of teeth that the ratio of number of teeth of a side's who is being connected with torque sensor 13 belt pulley 11 is installed in the belt pulley 4c on the rotating shaft 4a of motor 4 is many, makes belt pulley 11 with the rotative speed rotation slower than the rotative speed of motor 4.In other words, the rotative speed that is input on the torque limiter 13 by belt pulley 11 is slow.
On the opposing party's belt pulley 12, the toothed belt 16 by ring-type is connecting the belt pulley 17a that is installed on the axle 17.In other words, establishing toothed belt 16 being installed in the belt pulley 17a on the bearing 7 and being connected to reel between the belt pulley 12 on the torque limiter 13 to open.The two ends of axle 17 are installed on the base component 10 by bearing 10 with rotating freely.In addition, other belt pulley 17b is installed on axle 17.On this belt pulley 17b, at it and be installed in to reel to open between the belt pulley 5b on the rotating shaft 5a of separate roller 5 and establishing endless belt toothed belt 18.This belt pulley 12, toothed belt 16, belt pulley 17a, belt pulley 17b, toothed belt 18 and belt pulley 5b play a part the 3rd transmission mechanism of the present invention.Many with the number of teeth of the belt pulley 17a of ratio of number of teeth separate roller 5 sides of torque limiter 13 bonded assembly the opposing party's belt pulley 12, make belt pulley 12 with the rotative speed rotation slower than the rotative speed of separate roller 5.In other words, it is slow to be input to the reverse rotative speed of torque limiter 13 by belt pulley 12.
Below, the action of the separation device 1 of formation as described above is described.
At first, by carrying road 2 to carry under the state of pages, when motor 4 rotations make conveying roller 3 when arrow T direction is rotated, be rotated with the separate roller 5 of conveying roller 3 running contacies.
At this moment, the first, because it is many to be located at the belt pulley 3b number of teeth that the ratio of number of teeth of the belt pulley 4b on the rotating shaft 4a of motor 4 is installed on the rotating shaft 3a of conveying roller 3, so conveying roller 3 is with the rotative speed rotation faster than the rotative speed of motor 4.In other words, even when making rotative speed with the conveying roller of page delivery speed basically identical make the processing speed high speed of page at a high speed, the rotative speed of motor 4 can be not fast like that yet.
Second, after the rotative speed of motor 4 has been set in the lowland as described above, because it is few to be located at the side's that the ratio of number of teeth of the belt pulley 4c on the rotating shaft 4a of motor 4 is connected with torque limiter 13 the number of teeth of belt pulley 11, therefore belt pulley 11 is with the rotative speed rotation slower than the rotative speed of motor 4, and the rotative speed that is input to torque limiter 13 from motor 4 sides is extremely slow.And, few with the skin number of teeth of the ratio of number of teeth of separate roller 5 side bonded assembly belt pulley 17a and torque limiter 13 bonded assembly the opposing party's belt pulley 12, therefore, belt pulley 12 is with the rotative speed rotation slower than the rotative speed of separate roller 5, and the reverse rotative speed that is input to torque limiter 13 from separate roller 5 sides is extremely slow.
Therefore, under the state that separate roller 5 rotates together along with conveying roller 3, can make backward two rotative speeds that are input to torque limiter 13 extremely slow, can make the relative velocity of the load that becomes torque limiter 13 minimum, can make the load of torque limiter 13 minimum.Thus, after making the processing speed high speed of page, the load of torque limiter 13 can be reduced at a high speed, the service life of torque limiter 13 can be prolonged at the rotative speed that makes conveying roller 3.
In addition, when page being sent between conveying roller 3 and the separate roller 5 by conveying road 2, being transferred overlappingly with the plurality of sheets of paper page or leaf is that condition is carried along carrying road 2 former states to be in a piece of paper page or leaf of the coincidence direction end of conveying roller 3 sides unchangeably, and second later page separated by separate roller 5.At this moment, on separate roller 5, transmitting rotary driving force by torque limiter 13, giving and the rightabout torque of the throughput direction of page from motor 4 as moment of torsion.And, be stopped or be reversed to 5 moments of separate roller, separate overlapping the page that is being transferred.
As mentioned above, according to present embodiment, after the rotative speed that makes conveying roller 3 is faster than the rotative speed of motor 4, the rotative speed that makes belt pulley 11 is slower and make the rotative speed of belt pulley 12 slower than the rotative speed of separate roller 5 than the rotative speed of motor 4, and it is poor to reduce the rotative speed that is input on the torque limiter 13.Therefore, after having reduced the load that is applied on the torque limiter 13, the delivery speed high speed of page can be made, treatment effeciency can be improved.
Below, with reference to Fig. 3 the second embodiment of the present invention is described.
For with the identical symbol of inscape mark of separation device 1 said function of above-mentioned first embodiment, omit its detailed description.
According to the separation device of present embodiment, on the belt pulley 4c that is located on the rotating shaft 4a of motor 4, connecting belt pulley 21 by toothed belt 15a, and, on the belt pulley 21a that is provided with coaxially on this belt pulley 21, connecting belt pulley 11 by toothed belt 15b.The number of teeth of ratio of number of teeth belt pulley 4c by making belt pulley 21 is many, and makes the number of teeth of ratio of number of teeth belt pulley 21 of belt pulley 11 many, rotative speed that can double reduction motor 4.In addition, on the belt pulley 17a that is connected separate roller 5 sides, connecting belt pulley 22, in addition, on the belt pulley 22a that is arranged on coaxially on this belt pulley 22, connecting belt pulley 12 by flute profile belt 16b by flute profile belt 16a.The number of teeth of ratio of number of teeth belt pulley 17a by making belt pulley 22 is many, and makes the number of teeth of ratio of number of teeth belt pulley 22a of belt pulley 12 many, with the reverse rotative speed of double reduction separate roller 5.
Thus, compare, can further make from two directions and be input to rotative speed step-down on the torque limiter 13, the load that is applied on the torque limiter 13 is diminished with above-mentioned first embodiment.Therefore, by further the rotative speed of motor 4 being controlled to be the delivery speed high speed that can further make stationery at a high speed, can not increase the load that is applied on the torque limiter 13 in this case yet.
In addition, the present invention is not limited to the above embodiments, can carry out all modification within the scope of the invention.For example, in the above-described embodiment, use the situation of a motor 4 to be illustrated to drive source, still as separation device, also be not limited to this, also can utilize from making separation device work by the propulsive effort of carrying road 2 to carry the conveying mechanism transmission not shown in the figures of page.In this case, also can be used in drive source that conveying roller 3 rotation drives and to give the drive source of separate roller 5 with moment of torsion independent respectively.But, no matter under any circumstance, for by carrying page to improve treatment effeciency at high speed, behind the rotative speed of the such speedup drive source of the present invention, pass to conveying roller 3, input to torque limiter behind the rotative speed in deceleration source, and to input to torque limiter 13 these technology behind the rotative speed of deceleration separate roller 5 are actvies.
What as above illustrate is such, and page of the present invention separates conveying mechanism owing to have formation as described above and effect, can reduce the load of torque limiter, can carry and the separation page by at high speed, can improve treatment effeciency.
