Book pressing mechanism includes the guide rail 6 being fixed on book laying board 3, and sliding block 7, sliding block 7 and guide rail 6 are provided on guide rail 6 It is locked by the way that T-type lock screw 8 is fixed, is fixed with bearing block a9 on sliding block 7, connecting shaft 10 is provided in bearing block a9, connect Axis 10 is connected with linking arm 11, small connecting plate 12 and shell 13 in turn, and shell 13 covers in partial frictional wheel 16 and blade wheel 15 Wherein, shell 13 is connected with 14 both ends of rotation axis, and rotation axis 14 is connected with motor a, and motor a is direct current generator, and revolving speed is 500r/min is disposed with friction pulley 16 and blade wheel 15, settable friction pulley 16 two and blade wheel 15 in rotation axis 14 One, friction pulley 16 is coated with damping abrasion resistant layer, and the blade of blade wheel 15 is silica gel blade, and the wheel footpath of blade wheel 15 is greater than Friction pulley wheel footpath, friction pulley 16 and blade wheel 15 are located at upper 3 top of book laying board and close to upper book laying board 3, friction pulley 16 and blades Wheel 15 is center axis with rotation axis 14 and rotates with rotation axis 14 that rotation axis 14 is parallel with upper book laying board connecting shaft 2.
It includes the motor cabinet 18 being fixed on mounting base 4 that paper, which sticks up mechanism, and motor b is provided in motor cabinet 18, electricity Machine b is DC speed-reducing, and revolving speed 24r/min, motor cabinet 18 is on upper 2 one end of book laying board connecting shaft, motor cabinet 18 It is fixed with bearing block b26, square head shaft 17 is provided in bearing block b26, motor b is connect with square head shaft 17, and square head shaft 17 is connected with 19 one end of swing arm, 19 other end of swing arm are connected with sticky paper wheel 21 by spring 20, and sticky paper wheel 21 is nylon wheel, nylon wheel periphery It is enclosed with stickiness coating, sticky paper wheel 21 can be swung between antiskid rubber 5 and upper book laying board 3 with swing arm 19, and sticky paper wheel 21 is swung It is not contacted in the process with upper book laying board 3, the swing angle of swing arm 19 is 130 °~150 °.
A kind of main component effect of automatic page turning device of the present invention is as follows:
The rotational angle of the adjustable upper book laying board 3 of upper book laying board connecting shaft 2, book laying board 3 in supported underneath of support rod 22, With the active angle of fixed upper book laying board 3.
Antiskid rubber 5 for fixing paper bottom page, avoids its moving influence page turning during page turning because of its rough surface Be normally carried out.
Page pressing rod 24 will be pushed aside before being used for page turning around screw a rotation, and being put into reverse page pressing rod 24 after page turning paper makes It pushes down last page paper, is limited by screw b23 to page pressing rod 24 after reversing.
Sticky paper wheel 21 is sticked up the band page turning paper on antiskid rubber 5 using its circumferential surface viscous coating, this stickiness applies Layer can easily stick up a piece of paper, but not leave a trace or paper is glued to break and can be repeated several times and stick up paper, in motion process The stickiness of sticky paper wheel 21 makes the sub- rotation of paper tape driving wheel, and the sticky stuff of wheel surface is made to be fully utilized.
To guarantee that sticky paper wheel 21 does not contact during the swing with upper book laying board 3, as shown in Fig. 2, motor cabinet 18 is close to peace The angle of the side wall and 4 long side of mounting base that fill 4 long side of bottom plate is 22 °, as shown in fig. 6, motor cabinet 18 is fixed with bearing block b26 Upper surface and mounting base 4 between angle be 15 °.
Sliding block 7 can adjust its position on guide rail 6 according to page turning paper size, to meet friction pulley 16 and blade wheel 15 contact with paper.
The blade of blade wheel 15 is soft silica gel material, and the paper that blade wheel 15 glues sticky paper wheel 21 when rotating is dialled Enter below friction pulley 16.
Friction pulley 16 is coated with damping abrasion resistant layer, and when rotation can be very good to prevent paper from gliding, but not by paper It pulls open or leaves a trace, so that there is suitable frictional force between friction pulley and paper, tense paper simultaneously when friction pulley 16 rotates Paper is pushed down by its pressure, prevents paper from springing back.
Patch type photodiode 27 for detecting optical signal, during page turning patch type photodiode 27 always by The optical signal that paper covering detects is weaker, and when page turning only remains last paper that page pressing rod 24 is pushed down, patch type is photosensitive The optical signal enhancing that diode 27 detects controls motor a and motor b at this time and stops working, extra page turning is avoided to act.
A kind of course of work of automatic page turning device of the present invention is specific as follows:
Books to page turning are placed on antiskid rubber 5, page pressing rod 24 is stirred by books last page and is pressed into page pressing rod Under 24, the length of support rod 22 and the position of sliding block 7 are adjusted according to the size of paper, opens motor a and motor b, 19 band of swing arm Dynamic sticky paper wheel 21 moves downward, and clings paper, and then swing arm 19 drives sticky paper wheel 21 to move upwards and sheet movement is driven extremely to turn Paper engaging friction wheel 16 is stirred by blade wheel 15 in the following, rubbing at this time as swing arm continues to rotate in the edge of dynamic blade wheel 15 It wipes wheel to separate with paper, paper is tensed and push down paper by its pressure and prevents from springing back by the friction pulley 16 of rotation.It puts at this time Arm 19 by backswing until sticky paper wheel 21 clings next paper, press when paper only remains page pressing rod 24 by the above-mentioned page turning movement of repetition When last page firmly, patch type photodiode 27 blocks the optical signal enhancing that light source detects without paper at this time, according to patch The variation of 27 output optical signal of chip photodiode, control motor a and motor b stop working, and the page turning of the books is fully completed.
A kind of automatic page turning device of the present invention compared with prior art the invention has the following advantages that
One, page turning is high-efficient: can be achieved page turning 57 times per minute or more, can be used for archives books page turning scanning, page turning is beaten Print etc.;
Two, error is small: since paper is to be sticked up by 21 surface of sticky paper wheel, and the motion profile of paper is in oblique camber line, phase For other page turning modes, there is no once turn over page two or even multipage;
Three, safe and reliable: motor a and motor b of the invention is all made of 24V direct current generator, and voltage is safer.
