Description
Technical field
The present invention relates to a kind of automatic page turning machine, be used for the copying and scanning equipment technical field.
Background technology
People use the scanner scanning books at present, generally need to use handspring one page, scanning one page, and this needs the people to wait on one side, and it is low again promptly to take manpower effectiveness.Be head it off, the machine that need a kind ofly can turn over book automatically is laborsaving for people save worry.
Find Chinese patent application number by literature search: 95215254.1, this patented technology discloses a kind of electronic automatic page turning structure, mainly is made up of page turning mechanism, press strip reciprocator and original copy cover plate switching mechanism three parts, and each several part is by motor-driven.These invention characteristics are, utilize vacuum cup to hold page, increase times mechanism and cam mechanism etc. by stroke then and promote the slide bar motion, and then finish and turn over the book action.Books fixedly be to adopt vacuum cup and press strip to finish.The pull of vacuum of this invention produces and control by vavuum pump, vacuum solenoid, vacuum pipe etc., the vacuum system more complicated.In addition, utilize fixedly books instability of vacuum cup, reason is that sucker can only adsorb books surface paper, utilizes the front cover of absorption book to fix books, and the size of books bed knife will depend on the toughness of book cover paper fully.This invention is turned over book and is not possessed invertibity, only can unidirectionally turn over book.
Summary of the invention
The objective of the invention is at the above deficiency that exists in the prior art, a kind of automatic page turning machine that is applied on the scanner is provided, make it not only can unidirectionally turn over book, can also oppositely turn over book, and possess characteristics such as volume mini system in light weight is simple.
The present invention is achieved by the following technical solutions, the present invention includes: page turning mechanism, fixed mechanism, page turning platform and switching mechanism four parts.Its connected mode is: page turning mechanism just has been connected in the page turning platform outside, and fixed mechanism is fixed on the page turning platform, and wherein the brake portion of fixed mechanism is positioned at the page turning platform back side, and working portion is positioned at page turning platform working face top, and switching mechanism is connected with the rotating shaft of page turning platform.
Page turning mechanism comprises: sucker, the page turning bar, sucker disk seat, first decelerator, second decelerator, motor cabinet, flip vertical motor and flip horizontal motor, its connected mode is: motor cabinet inside is provided with the flip horizontal motor that flip vertical motor that control page turning bar rotates and control page turning bar rotate on horizontal plane in vertical plane, motor cabinet is bound up in the page turning platform on the front end side with coupling seat, wherein the flip horizontal motor is positioned at the flip vertical motor lower portion, the flip horizontal motor links to each other with first decelerator, the first decelerator output drives the motor cabinet that connects the flip vertical machine, makes motor cabinet and flip vertical motor, the page turning bar, sucker disk seats etc. rotate in horizontal plane.The flip vertical motor is connected with second decelerator, and the second decelerator output connects the page turning bar.The page turning boom end is equipped with sucker disk seat, and sucker disk seat is two-sided respectively to be furnished with a plurality of suckers.Sucker is bowl-shape, and a plurality of suckers are contained on the sucker disk seat positive and negative, makes sucker disk seat have two-sided adsorption function.During work, sucker disk seat is pressed on the page by the rotation of page turning motor, and extrudes air formation pull of vacuum in the sucker by pressure, and by the inner two-way valve switch of control sucker disk seat, can control having or not of the interior pull of vacuum of sucker.
The present invention has two fixed mechanisms that structure function is identical.Fixed mechanism comprises: fixed electrical machinery, reel, strand cable, spring attachment, depression bar, compressing tablet.Its connected mode is: the fixed electrical machinery output connects reel, twines strand cable on the reel, and strand cable links to each other with spring attachment, constitutes the brake portion of fixed mechanism jointly, is positioned at the page turning platform back side.Spring attachment links to each other with compressing tablet by depression bar, and compressing tablet is positioned at directly over the page turning edge of table.Wherein depression bar, compressing tablet constitute the working portion of fixed mechanism.
Spring attachment is made of spring, guide groove, baffle plate, pull bar and removable pin.Wherein the baffle plate retaining is before guide groove, and pull bar is through the hollow guide groove.Pull bar one end and depression bar hinge joint, the pull bar middle part is connected with the spring tempering, and the pull bar other end links to each other with strand cable.The depression bar end is connected with compressing tablet, and compressing tablet is positioned at directly over the page turning edge of table.Removable pin is contained on the page turning edge of table outside, and depression bar forms a fulcrum by removable pin with removable pin.
The normal condition lower spring is in compressive state, and compressing tablet is pressed in turn over the book platform or turns on written on the book platform.Have only fixed electrical machinery to rotate to make pull bar to the middle part pulling and continue the compression spring, the compressing tablet that spring has just been connected turns over book table top and expansion because the motion of pull bar is left.When fixed electrical machinery stopped, because the effect of spring force, compressing tablet set back, and recovered to be pressed on the state that turns on the book platform.Therefore fixed mechanism has two duties, and the compressing tablet that compressing tablet releasing orientation when promptly fixed electrical machinery starts and fixed electrical machinery stop to press state.
The page turning platform is made of the tabular table top and the positioning convex strip of a concavity, tabular table top and positioning convex strip cooperate, the main weight that plays carrying books and page turning mechanism, fixed mechanism etc., wherein positioning convex strip is positioned on the page turning platform front, mainly plays the books effect of preliminary location.
Switching mechanism is made of upset motor and the 3rd decelerator, and the upset motor is connected with the rotating shaft of page turning platform by the 3rd decelerator, and the vertical line of upset electrical axis and page turning platform is vertical.The switching mechanism major function is to utilize the output of upset motor by the 3rd decelerator, makes the page turning platform can be turned to the angle of requirement according to instructions for use around the rotating shaft of page turning platform.
The present invention adopts the multiple degrees of freedom sucker to realize turning over book, have simple in structure, reliably, can also easily realize forward and reverse characteristics of turning over book, can be used as piano turns over spectrometer and is the auxiliary reading device of disabled person service, also can be applied to these equipment be possessed turn over this function of book automatically on the many equipment of scanner.
