Operation program when the pneumatic automatic page turning of the utility model mechanism works is summarized as follows:
(1) original copy cover plate 4 is in ° position, α=145 (Fig. 3) before the work beginning, and slider-rocker mechanism is in OA
1B
1The position, press strip 15 is in position shown in Figure 1, and the books 19 usefulness books vacuum cups 18 that are copied hold fixing, face upward on the inner plane that places original copy cover plate 4;
(2) the right chamber that work beginning, compressed air enter cylinder 1 promotes piston and moves to left, and the gear 11 that piston rod promotes to increase times mechanism rolls left, moves to left with the connected slide block 16 of carry-over bar 12 drives of gear 11 engagements, and slide block 16 is from B
1Move to B
2 Promote rocking bar 13 with hinged 17 on the connecting rod of slide block 16 from the A point and clockwise rotate, by OA
1Go to OA
2Page turning vacuum cup 14 work that are hinged on the rocking bar 13C point pick up page.
(3) when cylinder 1 drives from right chamber, compressed air is also connected in the right chamber of cylinder 2, piston rod moves to left, and promotion gear 8, fixed rack 7 and carry-over bar 9 formed increases a times mechanism, the press strip 15 that is connected with carry-over bar 9 is moved to left, and press strip 15 is pushed down the page that has been adsorbed by page turning vacuum cup 14 while moving.
(4) forward OA to when rocking bar 13
2Behind the position, because the effect of translating cam 20, make the rotating shaft 25 of slider-rocker mechanism and the roller 26 that connects together is with it upwards carried from the O point, make page turning vacuum cup 14 at rocking bar 13 from OA
2Turn to OA
3The time, bring up to top (on the outerplanar) of original copy cover plate 4.
In this process, press strip 15 continues to move to left under the driving of cylinder 2 and push down page, when rocking bar 13 arrives at OA
2Behind the position, page turning vacuum cup 14 stops to adsorb page.
(5) go to OA when rocking bar 13
3Behind the position, cylinder 1 and 2 right chamber stop air inlet, slider-rocker mechanism and all stop motions of press strip 15, and the right chamber of cylinder 3 begins to enter compressed air (Fig. 3), piston rod promotes tooth bar 6 and is moved to the left, clockwise rotate with tooth bar 6 meshed gears 5, cause original copy cover plate 4 (Fig. 3 shown in the dotted line) upset clockwise from ° position, α=145.
(6) when original copy cover plate 4 forwarded ° position, α＜45 clockwise to, compressed air entered the left chamber of cylinder 2, and press strip 15 moves to right and gets back to after the origin-location, and the left chamber of cylinder 2 stops air inlet; Simultaneously original copy cover plate 4 continues to clockwise rotate, up to the books 19 that are copied arrive at lie on the original copy glass 23 till, this moment, the right chamber of cylinder 3 stopped air inlet, duplicator begins to duplicate then.
(7) finish when this page duplicating of books 19, the left chamber air inlet of cylinder 3, original copy cover plate 4 upwards rotates counterclockwise, and exhaust hood 1 left chamber air inlet, slider-rocker mechanism is from OA
3B
3The position is toward original OA
1B
1The position motion.When original copy cover plate 4 transferred back to ° position, α=145, slider-rocker mechanism was also got back to position OA shown in the original solid line of Fig. 2
1B
1, then the left chamber of cylinder 1 and cylinder 3 stops air inlet.
So far, the state before the entire mechanism work of returning to begins can descend the duplicating of one page.
The utility model mechanism enlarges and the perfect function of duplicator, the agent structure that needn't change the existing duplicator of repacking, and whole mechanism is uncomplicated, makes, installation, maintenance is easy, long service life.Except on duplicator, using, can also be used as the similar applications such as reading device of disabled person's service.
