Background technology
All be provided with conductive rubber pad (hereinafter to be referred as conductive pad) on the archives class paper perforating binding machine (hereinafter to be referred as binder) that uses at present, the function of conductive pad is the grooved bit after paper is punched in the pad support; While can be transmitted the signal of telecommunication through lead feedback electric control gear in the moment that drill bit touches conductive pad, thereby the control drill bit rises.Conductive pad generally is to be flush-mounted in the conductive seat, and for hand-operated binder, conductive seat is arranged on the base plate of binder; For automatic bookbinding machine, the conductive seat 3 of setting-in conductive pad 4 is arranged on the slide plate 2 on the base plate 1 of binder (as depicted in figs. 1 and 2).
When punching paper at every turn, beats all on drill bit that the pad support that causes this place's excessive wear to be brought at the same place of conductive pad was lost efficacy and conduction lost efficacy, usually want behind every dozen of several times holes conductive pad to be turned an angle, to make full use of each position of conductive pad, finish effective pad support and conducting function.Therefore, rotating conductive pad timely and effectively is to guarantee that binder finishes the important step that continues normal operation.
The early stage mode that realizes that conductive pad rotates is: shut down the artificial recruitment tool in back conductive pad is prized from conductive seat; put back in the conductive seat again behind the conversion direction; this mode is operated inconvenience, efficient is low; and, cause binder operation troubles and drill bit premature wear thus because of no location measure usually makes conductive pad dislocation undesirable.
Improvement to the conductive pad rotating manner subsequently is: conductive seat is divided into upper and lower two pedestals that are connected by rotary motion pair, and conductive pad embeds upper pedestal (referring to the inventor at the disclosed Chinese patent 200620072925 of first to file).The conductive pad of this structure rotates convenient, but still manual finishing after needing to shut down, efficient is not high, the job requirements of incompatibility automatic bookbinding machine yet.
For automatic bookbinding machine, require the rotation of conductive pad fast automaticly to finish, the automatic tumbler of conductive pad has appearred in design for this reason.The whirligig of the drill support sole plate in a kind of punching machine of automatic bookbinding machine is disclosed as the Chinese patent of the patent No. 200410085256.3.Though the whirligig of this patent has been awarded a very grands droits scope that limits with the functional character literal, the inventor thinks the technical scheme that only can draw a kind of concrete whirligig from the full text of this patent.This technical scheme is: be interval with four rotating shafts on the slide plate on the base plate of binder successively; Coaxial drill support sole plate retainer and the swing pinion of being equipped with in first rotating shaft, drill support sole plate retainer and swing pinion lay respectively on the upper and lower surface of slide plate; In second rotating shaft, idler gear is housed; The coaxial rocking arm that driven wheel, ratchet and built-in one-way clutch are housed in the 3rd rotating shaft; In the 4th rotating shaft, be equiped with S word arm; Swing pinion and idler gear engagement, idler gear meshes with driven wheel again; S word arm one end is provided with and is crimped on the ratchet that intermittently limits the ratchet rotation on the ratchet; The free end of rocking arm is divided into two and is the U font, and the card shotpin card that hangs down from pedestal extend into the free-ended centre of rocking arm U font.The inventor be sure of after by the full text that reads over this patent: each technical characterictic in the technique scheme is all indispensable, otherwise can't realize this patent problem to be solved and and reach corresponding effect; Can not learn simultaneously except this technical scheme, to also have what other technologies scheme can realize this patent problem to be solved and corresponding effect.Opposite is that the inventor thinks: the frame for movement that technique scheme embodies is very complicated very, not only makes inconvenience, manufacturing cost is high, and operational failure rate height, easy-maintaining, service life are not short; Therefore beyond technique scheme, be necessary to design the other technical scheme that is different from this technical scheme fully.
Summary of the invention
The technical problem that the present invention solves is: at the disadvantage that the whirligig of the conductive pad of above-mentioned existing automatic bookbinding machine exists, propose a kind of simple in structure, low-cost, fault rate is low, be convenient to make maintenance be used to make the full-automatic binder conduction pad device of rotation automatically.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of full-automatic binder conduction pad rotation device, comprise and be located at chute and the slide plate that forms moving sets on the automatic bookbinding machine base plate each other, described slide plate one end is equiped with first and second liang of rotating shafts at interval, described first rotating shaft is passed slide plate and is equiped with the conductive pad that lays respectively at above the slide plate and the ratchet below the slide plate, described second rotating shaft is equiped with and is positioned at below the slide plate and is pressed on the ratchet that prevents ratchet counter-rotating on the ratchet one side ratchet, described ratchet is provided with elastic component, described chute is provided with to stagger with ratchet and is pressed on the elasticity push jack that on the described ratchet one side ratchet ratchet is just being changeed, and described elasticity push jack compresses the direction of ratchet and direction that ratchet compresses ratchet in the same way.
During use, after the drill bit of automatic bookbinding machine touches conductive pad, rise through lead feedback electric control gear control drill bit, controlling slide plate simultaneously moves backward from bore position, in slide plate moves backward, the dead end (free end) of the elasticity push jack on the chute compresses on the ratchet one side ratchet gradually and promotes the ratchet forward rotation (the elasticity push jack promotes ratchet of ratchet makes ratchet rotate a unit angle, promoting two ratchets of ratchet makes ratchet rotate two unit angles, by that analogy, the unit angle depends on the number of teeth of ratchet.), the conductive pad that the ratchet that turns an angle like this can drive in first rotating shaft turns an angle, slide plate continues to move backward to make ratchet leave the elasticity push jack, in the process that slide plate moves backward, staggering with the elasticity push jack is pressed on ratchet on the same side ratchet of ratchet and guarantees not reverse ratchet all the time conductive pad is completed just to be changeed to keep; Finish when pressing, slide plate is controlled to move forward when passing through the elasticity push jack once more, because this moment, ratchet was come from elasticity push jack rear, therefore the dead end of elasticity push jack can not be pressed on the ratchet of ratchet, the elasticity push jack presses to the chute side under the ratchet compressing, this moment, ratchet and elasticity push jack formed slip toward each other, thereby made ratchet and slide plate move forward smoothly, after slide plate moved forward and arrives bore position once more, drill bit descended and restarts boring; So repeatedly, move back and forth, can finish conductive pad and rotate continuously and automatically at a certain angle along with before and after the slide plate.
