Description
The present invention relates to the paper supplyor that a kind of paper finisher is used.
Known the paper supplyor that has paper finisher to use, this device promotes suction nozzle with one paper is picked up and promotes from feeding pile, is transferred the conveying facility reception that is provided with later after the direction then and is transported to paper finisher, for example prints the printer of unit.It should be noted that at that time promoting suction nozzle must rest on raised position for a long time till the trailing edge of received paper leaves the range of movement that promotes suction nozzle.Promoting suction nozzle afterwards could descend so that pick up down a piece of paper apace again.The known device that machinery is arranged, this device can guarantee to make the lifting suction nozzle to rest on the top of paper, and it just can be moved down after braking is unclamped.But the brake system of the costliness of this machinery seems that for high-revolving paper finisher action is too slow especially.This system is used for producing, at first is that take-off the brake needs a lot of times of spend, cause down a piece of paper to be delayed and lift, thereby print out rate will significantly reduce.But if too early take-off the brake promote the trailing edge that suction nozzle just might be run into paper, thereby paper may suffer damage, or paper snatched away from conveying facility subsequently, or the position of paper can be moved at least.This danger exists really when particularly drawing paper sucking machine as subsequently conveying facility.
A kind of simply can making promotes suction nozzle to make the terms of settlement of short stay is disclosed in Deutsche Reichspatent DD PS 293562 A5 numbers.Wherein promote suction nozzle and be with other and air-breathing it is remained on the raised position, this is air-breathing be by intake guide that increases on the paper sucking machine one promote on the contact level of suction nozzle from above apply effect.After paper trailing edge that the traction paper sucking machine receives left the range of movement that promotes suction nozzle, air-breathing in the intake guide that this root increases promptly gave interruption, promoted the mode that suction nozzle just can be common and descended fast so that receive a piece of paper down.The lifting suction nozzle of this suggestion be owing to need increase airway and air-breathing control are arranged, thus be non-normalizing expense, complexity with costliness.Maintenance face has that a horn shape is outstanding to become nose shape, therefore suction nozzle can not be rotated, and this rotation is often wished to do under the constraint that is provided with the rapid-action maintaining body in operation.The suction of air also must be harmonized very exactly so that tackle the deadweight that promotes suction nozzle.
Purpose of the present invention be substantially to develop that another is simple, promote use on the suction nozzle, can remove holding device its effect, flexibility and changeability fast.
Just can solve according to listed feature the problems referred to above in the claim 1 of the present invention.
Be contained in and promote the power source decline that continues the effect that applies to the pile direction on the suction nozzle with making the rapid reaction of lifting suction nozzle, in case the paper trailing edge leaves the scope that promotes suction nozzle, magneto motive maintenance facility just will promote suction nozzle and discharge.Magneto motive maintenance facility can be cancelled to rapid reaction to make and be promoted the magnetic force that suction nozzle remains on raised position.Magneto motive maintenance facility be simple and expense little.The intake guide of so just desirable digestion money.Control can be accomplished easily.Just can not occur and may produce dysgenic air misoperation paper sheet delivery yet.
Adopt the feature of claim 2 to make a simple structure by enough a small amount of facilities.
Adopt the feature of claim 3 to make an especially simply structure by enough simple controlled electromagnets.Electromagnetic field must be so selected at that time, make the magnetic force that keeps promoting suction nozzle to be overcome, and the magnetic force that keep to promote suction nozzle is to be caused with impelling the difference that promotes the power that suction nozzle moves down by the permanent magnet magnetic force that acts on the maintainance block, impels to promote power that suction nozzle moves down and comprise the gravity that promotes suction nozzle and the power of first power source generation.When the circuitry cuts of electromagnet,, the lifting suction nozzle is promoted rapidly owing to above-mentioned maintenance effect.The feature of claim 3 can especially promptly be eliminated the maintenance effect of permanent magnet, because cause the electromagnetic field may be more next hurry up than eliminating it.
Form of implementation according to claim 4 and 5 can be made the simple structure that can change money especially less by enough a small amount of facilities.Structure according to claim 6 is another the simple and effective form of implementation that can change money less.
According to the form of implementation of claim 7, make rapid reaction except making electromagnetic field, help the confining force of permanent magnet to make outside the lifting of lifting suction nozzle, can also obtain the repulsive force of electromagnetism from electromagnetic field.Be in raised position in case promote suction nozzle, just can connect the circuit of electromagnetic field, the magnetic force that it is produced surpasses the confining force of permanent magnet, and between electromagnet and permanent magnet, obtain a repulsive force, this repulsive force is applied to and promotes on the suction nozzle, add that the former there that acted on impels its downward power, for example promote the power that the gravity of suction nozzle and the first power source produce, impel to promote suction nozzle pile downwards and descend.Therefore can make the maintenance that promotes suction nozzle accomplish and to remove especially apace.
Following the present invention illustrates the embodiment that Fig. 1 to Fig. 9 draws in detail.
Wherein:
Fig. 1 promotes the front elevation of inhaling the paper unit on the sheet convey apparatus,
Fig. 2 promotes the top view of inhaling the paper unit for this,
Fig. 3 inhales the section-drawing that III among Fig. 1-III line is pressed in the paper unit for promoting, and is divided into two figure:
Lifting suction nozzle when Fig. 3 A is illustrated in lowering position,
Lifting suction nozzle when Fig. 3 B is illustrated in raised position,
Fig. 4 is that the lifting suction nozzle among Fig. 3 is inhaled the turned situation of paper part,
Fig. 5 is the embodiment that electromagnet and permanent magnet are housed on paper sucking machine,
Fig. 6 presses the section-drawing of VI among Fig. 5-VI line for magnet arrangement,
Fig. 7 be another kind of on paper sucking machine electromagnet and the embodiment of permanent magnet configuration,
Fig. 8 is another electromagnet on paper sucking machine and the embodiment of permanent magnet configuration,
Fig. 9 is for being contained in electromagnet on the paper sucking machine and permanent magnet is contained in the embodiment that promotes on the suction nozzle.
In the embodiments of figure 3, the position lifting that has an electromagnet 8 to be fixed tightly in to captive joint with crossbeam 2 above guiding cylindrical shell 4 is inhaled on the paper unit 1, as shown in Figure 1 to Figure 3.Form an impingement area on the top that promotes suction nozzle 5, on this impingement area, be provided with one with the concentric circular groove of lifting suction nozzle, a ring 9 of being made by magnetisable material in embedding securely in this circular groove.
When promoting suction nozzle when pile picks up a piece of paper, promote suction nozzle 5 since by the suction of air-breathing adapter 3 remove air, the action of the spring that overcomes spring 16 promotes, until the collision of its impingement area is till on the electromagnet 8.At that time because electromagnet is switched on, and electromagnetic field is established, when paper be arranged on by sheet transport direction the back, after traction paper sucking machine that do not draw, that have common structure receives on the figure, aspirated air just can cut off.Promote suction nozzle is maintained at lifting owing to the electromagnetic force of electromagnet 8 position.In case when the paper of being carried by the traction paper sucking machine leaves the range of movement that promotes suction nozzle, make and the circuitry cuts of electromagnet can be removed electromagnetic field.Because the deadweight of the retracing spring power of spring 16 and lifting suction nozzle 5 promotes suction nozzle and can immediately go to following so that receive a piece of paper down.The lift stroke that promotes suction nozzle at that time is owing to a guiding spring 14 that is fixed tightly on the paper sucking machine is restricted (see figure 1).
As shown in Figure 4, such lifting suction nozzle 5 can according in the operation need be around himself rotational, therefore can make often can not be parallel with paper on the pile the paper 17 of getting rotate.
In the embodiment shown in Fig. 5 and Fig. 6, have one securely with paper sucking machine on the electromagnet 10 that links of crossbeam 2 be fixed tightly on the plane with lifting suction nozzle axis normal.This electromagnet 10 has one to be wound on coil 13 on the iron core by common mode.With coil 13 coaxial also tightening up one with coil 13 series connected permanent magnets 11.Tightening up a holding plate 19 of making by magnetisable material in the upper end that promotes suction nozzle 5.Pick up a piece of paper towards being right after lift stroke buting iron electromagnet 10 below when promoting, though the electromagnetic field of the circuitry cuts permanent magnet 11 of electromagnet still can attract annular holding plate 19 in case promote suction nozzle 5 from feeding pile.Because making, the confining force of this sucking action promotes suction nozzle 5 still can remain on rising after the inspiratory flow by air-breathing adapter 3 stops position.In case paper is owing to the traction paper sucking machine of next connecting is able to fully when the range of movement that promotes suction nozzle leaves, the circuit of electromagnet 10 is just connected, and makes it self can produce a magnetic field opposite with the magnetic field of permanent magnet.The size of this electromagnetic field is chosen such that and makes the power of being synthesized by two magnetic fields less than facilitating the power that suction nozzle moves downward that promotes.Therefore electromagnetic force is selected as making it can offset the power that permanent-magnetic field produces.
And both sides and the permanent magnet 11 and 12 that can imagine electromagnet be cascaded, as shown in Figure 6.
Fig. 7 illustrates another embodiment of series connected like this electromagnet, permanent magnet device.Here the tandem arrangement by electromagnet 13 ' and permanent magnet 12 ' forms is arrangement like this, make the permanent magnet device axis and promote suction nozzle parallel axes, electromagnet apparatus axis and promote the suction nozzle axis normal, be higher than another on the paper sucking machine and be fixed on cylindrical iron core 20 on the paper sucking machine and be fixed on by the tandem arrangement that permanent magnet and electromagnet are formed.Its mode of action is with embodiment illustrated in fig. 6 identical.By the permanent-magnetic field of permanent magnet 12 ' cause,, be to act on the magnetizable holding plate 19 that is fixed tightly on the lifting suction nozzle 5 by unshakable in one's determination 20 by the magnetic confining force of permanent magnet 12 ' generations by unshakable in one's determination 20 further diffusions.This lifting state can be used for the maintenance that electromagnet is offset permanent magnet changing.
Fig. 8 is on the coaxial permanent magnet 24 that is fixed tightly in a jar shape and be fixed on the paper sucking machine one and comprise bobbin frame 22 and coil 23 with the coaxial electromagnet 21 of lifting suction nozzle.Tightening up the holding plate 25 of an annular at the top that promotes suction nozzle 5.In raised position, this holding plate 25 abut against an annular, with promote suction nozzle coaxial, be fixed tightly on the energy disperser 28 between permanent magnet 24 and the electromagnet 21, permanent magnet magnetic force acts on the holding plate 25, makes to promote suction nozzle and remain on the raised position.After the circuit of electromagnet was connected, the magnetic force that holding plate 25 and lifting suction nozzle 5 are kept was just cancelled.Promoting suction nozzle 5 just will move downward so that pick up down a piece of paper according to the mode of having said.
In the structure of Fig. 9, without the jar shape magnet 24 among Fig. 8 embodiment but with the holding plate 27 of one jar of shape as stop block.At the top that promotes suction nozzle 5 without the holding plate among Fig. 8 embodiment 25 but tightening up a coaxial annular permanent 26 that promotes on the suction nozzle that is contained in.Promote suction nozzle 5 and can upwards rise to permanent magnet 26 collisions till on the stopping surface 27 always.Because the magnetic force of permanent magnet 26 makes lifting suction nozzle 5 still can remain on raised position after air-breathing cut-out.In case the paper of being carried by the traction paper sucking machine leaves the range of movement that promotes suction nozzle fully, electromagnet 21 ' circuit just can connect.Produce an electromagnetic field opposite at that time with the permanent magnet field action direction.This electromagnetic field can so design, make by electromagnet 21 ' and the magnetic force that produces of permanent magnet 26 make a concerted effort promote gravity and the spring force that suction nozzle 5 moves downward less than making.Therefore electromagnet 21 ' circuit connect after, the maintenance effect of permanent magnet just promptly disappears.Promoting suction nozzle can move downward so that pick up down a piece of paper by the mode of having stated.
And can imagine with electromagnet 21 ' the size design of electromagnetic field must be also bigger than permanent-magnetic field, make after the circuit of electromagnet is connected, electromagnet 21 ' with permanent magnet 26 synergy under, magnetic force plays the effect of repulsion; Like this, after the circuit of electromagnet is connected, promote suction nozzle 5 and also will be promoted downwards by magnetic force except the effect that is subjected to gravity and spring force, therefore promoting suction nozzle can descend especially apace.
And can imagine, select for use magnetic direction can control and the electromagnet 21 of conversion '.So just, can keep doing time spent electricity consumption magnet and apply an electromagnetic field simultaneously the magnetic field of permanent magnet 26 is further strengthened will producing.And keep doing the time spent magnetic direction of electromagnet is changed will removing, so just can remove confining force.Also can imagine herein, electromagnetic field can be adjusted to size like this in this case, make it except removing the maintenance effect, also can under electromagnet and permanent magnet 26 synergy, produce magnetic repulsion, try hard to recommend the moving suction nozzle 5 of lifting down at this and can quicken to move downward.
In the embodiment of Fig. 9 and can imagine, with an energy disperser 28 be fixed tightly in stop block 27 and electromagnet 21 ' between.
