The present invention relates to facsimile apparatus, specifically, relate to a kind of device, be used for separating the file of forming by a large amount of pages exactly, make it to be suitable in facsimile apparatus transmission page by page and with every file of time gap auto-feed of rule.
Be used for the application at the device of facsimile apparatus automatic feeding file based on korean application No. 38754/1995, this application file is attached to here as comprehensive reference.
Usually, at a kind of conventional equipment that is used for the file that auto-feed is made up of a large amount of pages, such as transfer transmitter, if when a large amount of pages are packed the paper feeding device into, produce a certain transmission signal, the said apparatus of facsimile apparatus just begins from each page of a nethermost file that feeding is page by page in order adorned, and gives the other side the information transfer that needs by means of the image that scans feeding page.
At this moment, for a large amount of pages of feeding page by page continuously, use a kind of device that is shown in Fig. 1.At this, Fig. 1 is a plan view, show a kind of conventional equipment that is used at the facsimile apparatus automatic feeding file, and Fig. 2 is a decomposition diagram, shows the vital parts that is used at a kind of conventional equipment of facsimile apparatus automatic feeding file.
In Fig. 1, cylindrical automatic paper feeding roller 2 is fixed on the middle part of the automatic paper feeding roll shaft 3 of automatic paper feeding roller 2, be used for being contained in each page 1 of paper feeding device, and paper feeding roll shaft 3 is bearing on the frame 4 to rotate automatically from the feeding of page forward position.Paper feeding sheet rubber 21 is can be selectively mutually close with automatic paper feeding roller 2 by means of spring 22.
Automatically an end of paper feeding roll shaft 3 pack into sleeve 5 cylindrical shape part 5a and fixed.The cylindrical shape part 5a of the cylindrical shape part 7a of one automatic paper feed gear wheel 7 and sleeve 5 inserts among the clutch spring 6, and clutch spring 6 can stop or transmit the power that puts on automatic paper feeding gear 7 from a motor (not shown) and arrive automatic paper feeding roller 2.
Also have, cylindrical delivery roll 8 is fixed on the middle part of the transmission roll shaft 9 of delivery roll 8, and its position is parallel to automatic paper feeding roller 2 and transmits each page, is bearing on the frame 4 waiting and rotates and transmit roll shaft 9.One is being bearing on another frame during the page transmission to the pinch roll 11 that delivery roll 8 is exerted pressure.Transmit the end that gear 8a is fixed on the transmission roll shaft 9 of close frame 4, transmit rotative power from the outside to delivery roll 8.
Fig. 3 is a work view, shows that one is used to handle the clutch spring of conventional automatic paper feed rolls.
As mentioned above, if page 1 is fed to automatic paper feeding roller 2, paper feeding gear 7 and transmission gear 8a then rotate according to direction A automatically.So, as shown in Figure 3,, can be rotated and compress because clutch spring 6 places between the cylindrical shape part 5a of the cylindrical shape part 7a of automatic paper feeding gear 7 and sleeve 5.The power that puts on automatic paper feeding gear 7 reaches automatic paper feeding roll shaft 3 through clutch spring 6 and sleeve 5 from the outside, thereby automatic paper feeding roll shaft 3 is rotated according to direction A.
Because this rotation, page 1 is transferred into delivery roll 8 from automatic paper feeding roller 2, and a page is recognized and read device 23 and begin to recognize from the page forward position and read page simultaneously.Next, page 1 borrows friction force to send between pinch roll 11 and the delivery roll 8, and has the tension force of forcing when transmitting subsequently, and this tension force is that this situation of linear velocity that the linear velocity owing to automatic paper feed rolls 2 is lower than delivery roll 8 causes.
Along with the transmission of page 1, the linear velocity of the linear velocity convergence delivery roll 8 of automatic paper feeding roller 2.At the rotational sleeve 5 that is connected with automatic paper feeding roll shaft 3 with have that to have produced operation mutually between the automatic paper feeding gear 7 of constant speed poor, it is proportional to the length of page 1.This operation difference mutually is to be caused by the velocity contrast between automatic paper feeding roller 2 and the automatic paper feeding gear 7.The result, as shown in Figure 3, the spring clutch 6 of being rolled up pressure loosens gradually, form a gap between the interior periphery of the outer periphery of cylindrical component 5a and 7a and clutch spring 6, thereby paper feeding roller 2 begins rotation with the linear velocity that equates with delivery roll 8 automatically.
On the other hand, if the back edge of page 1 skids off automatic paper feeding roller 2, the automatic paper feed gear wheel 7 that rotates with constant speed turns over the angle that is equal to the size of operation difference mutually along direction A, thereby the clutch spring 6 round the cylindrical shape part 5a of the cylindrical shape part 7a of automatic paper feeding gear 7 and sleeve 5 is pressed towards A direction volume, and the gap between clutch spring 6 and two cylindrical portions may 5a and 7a is reduced.Automatically 7 of paper feeding gears rotate along the A direction with automatic paper feeding roll shaft 3.Therefore, the power that comes from the outside sends the automatic paper feeding roll shaft 3 of automatic paper feeding roller 2 to by sleeve, and next is opened page and supplies with automatic paper feeding roller 2 subsequently.
The result of aforesaid operations is, sleeve 5 and the operation difference mutually between the paper feeding gear 7 automatically be pick feed of formation between the back edge of the forward position of back one page 1 and last page 1, thereby makes each page be able to feeding one by one.
But, in the conventional equipment that is used for each page of auto-feed facsimile apparatus file, in order to realize aforesaid operations, playing the external impetus that stops or transmit automatic paper feeding gear in the effect of sleeve, the clutch spring must assemble fine with pin or (or two a) sleeve, so that form very small gap between clutch spring and each cylindrical part branch.Because a kind of like this clutch spring not a duck soup of assembling adopts this clutch spring will cause cost to improve.
And after each working gear engagement, because it is not firm to exist pressure or gear wheel shaft to fix between gear tooth, thereby the automatic paper feeding gear that is connected with automatic paper feeding roll shaft has the pressure moment of torsion two driven wheel places effects.So, when two gears just in time mesh, can cause operational issue.
Therefore, a project of the present invention be, a kind of device is provided, be used for each page of feeding facsimile apparatus file automatically, way is, automatic paper feeding axle and plastics are joined together and are not adopted pin or clutch sleeve by injection mo(u)lding (iijection molding), so just can be by the number of parts that reduces device its assembling operation of cost-cutting and simplification, thereby address the above problem.
Another purpose of the present invention is, a kind of device is provided, and is used for the file of feeding facsimile apparatus automatically, so as to prevent owing to come from automatic paper feeding axle or automatically the gear torque of paper feeding gear have problems.
These and other some purposes can adopt according to the present invention and a kind ofly be used for the device of each page of feeding facsimile apparatus file automatically and be achieved, this kind device comprises: a pair of projection, the upper and lower end that is arranged on automatic paper feeding roller of each projection, be used for power is passed to the automatic paper feeding roller of automatic page, this roller begins each page of feeding one by one from the paper feeding device from more following page; And automatic paper feeding gear, engage with automatic paper feeding roll shaft, thereby automatic paper feeding roll shaft can be rotated, in order to power is passed to automatic paper feeding roller, axis hole and motion eyelet are made in middle part at automatic paper feeding gear, so as to by sleeve automatic each page of feeding successively also of the pick feed between the back edge of the forward position of adjusting back one page of the operation difference mutually between the paper feeding gear and last page therewith, this gear support is on the gear case frame, two projections embed among the motion eyelet herein, thereby by automatic paper feeding gear power is passed to automatic paper feeding roll shaft, so as to reducing to be created in the application force on the automatic paper feeding roll shaft vertical direction and finally preventing the moment of torsion of automatic paper feeding gear.

Get back to Figure 4 and 5 now, will make in detail following according to operation instructions of the present invention.
Automatically the automatic paper feeding roll shaft 3 of paper feeding roller 2 is supported on a frame 4, from more than of paper feeding devices from the more following a large amount of pages of page feeding.In addition, make a pair of projection 3a in two parts place up and down at an automatic end of paper feeding roll shaft 3, each projection 3a is self symmetry of benchmark with automatic paper feeding roll shaft 3.
Among Fig. 5, the middle part of automatic paper feeding gear 30 1 sides of rotating under dynamic action is shaped on cylindrical axis hole 30a.Secondly, be benchmark, self make fan-shaped motion eyelet 30b symmetrically with automatic paper feeding roll shaft 3.Whereby, projection 3a can stretch out the width (thickness) that surpasses automatic paper feeding gear 30, and embeds from the motion eyelet 30b that axis hole 30a radially stretches.Once more, be shaped on the hole at the middle part of automatic paper feeding gear 30 opposite sides, thereby an axostylus axostyle of gear case fuselage 19 can insert the eyelet of gear 30 opposite side center.Therefore, automatically paper feeding gear 30 just is installed in gear case fuselage 19 places, so as to the moment of torsion that prevents automatic paper feeding gear 30 or formed the deflection of plastic shaft 3 by in vertical direction dynamic action.
As preceding pointed, understood specifically in prior art and produced the steel axle and embed bearing pin or the method for use clutch spring that the present invention will illustrate the method that connects automatic paper feeding gear in exclusive mode, so as to improving its function.
Become big owing to be positioned at the linear velocity of the transfer roller 8 at automatic paper feeding roller 2 anterior places, automatically the power of paper feeding gear 30 does not pass to automatic paper feeding roll shaft 3, wherein the power of transfer roller 8 passes to automatic paper feed rolls 2 by the conveying capacity of each page, a pair of projection 3a designs to such an extent that can rotate in the motion eyelet 30b the inside of automatic paper feeding gear 30, thereby paper feeding roller 2 rotates with the speed that equals transfer roller 8 speed automatically.
Be described as follows now according to every principle design-calculated of the present invention work effect of the present invention.
When the application force of paper feed sheet rubber 21 by spring 22 with paper feeding roller 2 jam-packeds automatically and page 1 when being sent to automatic paper feeding roller 2, the sensor (not shown) detects paper 1, power is passed to automatic paper feeding gear 30 from motor, automatic paper feeding gear 30 is rotated along the A direction.
Fig. 6 is a work view, is used to handle the automatic paper feeding gear of automatic paper feeding roller when showing according to feeding file of the present invention.
In the case, as shown in Figure 6, a pair of projection 3a that inserts automatic paper feeding gear 30 is pushed and rotates along the A direction.After this, along with the transmission of automatic paper feeding gear 30 power and the rotation of paper feeding roll shaft 3 automatically, paper feeding roller 2 rotates along the A direction automatically.Next, because the friction force of paper feeding sheet rubber 21, one in the page 1 is fed, and page 1 begins to recognize at page from one forward position wherein and reads device and recognized and read, thereby reads page and send transfer roller 8 to recognizing.
After this, one forward position arrives transfer roller 8 in the page 1, and is admitted between transfer roller 8 and the pinch roll 11, is being with tension force to transmit subsequently; This tension force is that the linear velocity that the linear velocity by automatic paper feeding roller 2 is lower than transfer roller 8 causes.
Fig. 7 is a view, shows the automatic paper feeding gear when file is placed in the transfer roller place according to the present invention.
Therefore, under the situation of linear velocity near the linear velocity of transfer roller 8 of automatic paper feeding roller 2, with automatic paper feeding roll shaft 3 bonded assembly rotational sleeves 5 and automatic paper feeding gear 7 with constant speed between can operation mutually that is proportional to page 1 length of generation poor.So, because being contained in the actuating speed of the automatic paper feeding roller 2 on automatic paper feeding roll shaft 3 stage casings becomes greater than the actuating speed of automatic paper feeding gear 30, as shown in Figure 7, the motion eyelet 3b the inside of a pair of projection 3a on automatic paper feeding gear 30 that is formed on the automatic paper feeding roll shaft 3 moves in the opposite direction, thereby automatically paper feeding roller 2 can be to rotate with the same linear velocity of transfer roller 8, so as to last transmission page 1.
Because this situation, the power of paper feeding gear 30 does not pass to automatic paper feeding roll shaft 3 automatically, and page 1 is all passed to edge thereafter by transfer roller 8.
Next, when the back edge of page 1 skids off automatic paper feeding roller 2, paper feeding roll shaft 3 transfixions automatically, one of motion eyelet 30b on the automatic paper feeding gear 30 that rotates with constant speed is contacting with a pair of projection 3a.Equally, during rotation, in automatic paper feeding roll shaft two projection 3a of 3 contacts and two motion eyelet 30b, under the state that power does not transmit, paper feeding roller 2 is owing to rotate again the page that continues is fed among sheet supply apparatus automatically.
As mentioned above, motion eyelet 30b and two projection 3a be formed to be moved missionary society mutually produce a pick feed between the forward position of the back edge of last page and back one page, thus page feeding one by one.
From above-mentioned obviously as seen, according to the present invention, by using two projection 3a that make as benchmark with automatic paper feeding roll shaft and the automatic paper feeding gear that is shaped on two motion eyelets 30 thereon with being mutually symmetrical, paper feeding operation is automatically to keep pick feed between each page and finishing under the situation of each page of feeding one by one, and feeding and the transmission one by one automatically of each page.
Secondly, because automatic paper feeding operation and page transmission operation all are to realize reliably that under the situation that does not have E shape circle, pin or sleeve so the invention has the advantages that, above-mentioned each part assembles easily, and its manufacturing cost can reduce.
In addition, another advantage of the present invention is, because the paper feeding gear is installed on the gear case frame automatically, so vertically act on the deflection that driving force on the automatic paper feeding roll shaft can stop reversing of automatic paper feeding gear or plastic shaft.
Since the present invention has done concrete diagram and explanation with reference to preferred specific embodiment herein, for those in the art skilled person, be that aforementioned is to make under the situation that does not depart from essence of the present invention and category in the various changes aspect form and the details apparently.
