Technical field

The present invention relates to a kind of paper aligning apparatus, the paper delivery device for sheet that uses it and sheet-fed press and paper alignment schemes.

Background technology

In the paper delivery device for sheet of sheet-fed press, transmit by the jaw arrangement of the paper after the printing element printing through the chain type grippers, unclamp dop above row's paper platform, fall, on the row's of overlaying paper platform.

At this moment, the front and back of the paper that falls and about the position be aligned, and stack with the state of aiming at.

As the device of this aligned position, for example there is the spy to open the paper aligning apparatus of the width position of the alignment paper shown in the flat 9-58920 communique.

This device is in the Width both sides of paper configuration paper alignment plate, makes paper alignment plate crank motion periodically on Width, the width position of alignment paper.

This paper aligning apparatus has: the antiquarian of regulating the width position of paper alignment plate corresponding to the dimension modifying of paper changes mechanism and makes the paper alignment plate periodically to the reciprocating swinging gear of paper.

Make the paper alignment plate be positioned at position with paper sidepiece butt by antiquarian change mechanism corresponding to the size of paper, therefore the paper alignment plate that makes both sides by swinging structure crank motion periodically, beat the both sides of paper, make the both sides position alignment of paper.

But the spy opens the device shown in the flat 9-58920 communique swings integral body such as antiquarian change mechanism and paper alignment plate owing to constituting by swinging gear, so the inertial mass of wobbling action becomes greatly.In addition, can have on Width than large deviation when paper falls sometimes, for example count the deviation of mm, therefore in order to tackle this situation, the reciprocating amplitude of paper alignment plate is a movement range, has for example surplus about 10mm.

Owing to these reasons, be difficult to make the paper alignment plate to be swung fast, the acceleration oscillation period is limited.

So, if can not quicken oscillation period, just can not increase the pushing number of times of paper alignment plate to the paper that falls, it is limited to improve paper alignment performance.

Summary of the invention

The object of the present invention is to provide a kind of paper aligning apparatus, the paper delivery device for sheet that uses it and sheet-fed press that increases the number of times of pushing paper and improve the paper alignment performance of the paper that stacks.

And, the invention provides and a kind ofly can fully tackle contingent paper aligning apparatus, the paper delivery device for sheet that uses it and sheet-fed press and the paper alignment schemes that produces the paper fall than large deviation and the paper that can improve the paper that stacks alignment performance at Width.

And then the invention provides a kind of paper aligning apparatus and printer of the paper alignment performance that can further improve paper.

In order to address the above problem, the present invention adopts with lower device.

That is, first mode of the present invention is a kind of paper aligning apparatus, is configured in the direct of travel both sides of the paper of discharge, alignment width position when stacking this paper, it is characterized in that having: moving-member, framework is provided with on described Width movably relatively; Antiquarian change mechanism moves this moving-member on described Width; Push part can be installed in the described paper side of described moving-member movably on described Width; And near away from mechanism, the predetermined moment make this push part near or away from described paper.

In the paper aligning apparatus of the manner, when the change of the width of paper, make the work of antiquarian change mechanism, moving-member is moved to the Width of paper, the position of push part is moved to position with paper both sides butt.Under this state, by near make away from mechanism push part to the Width of paper near or away from the time, the paper that the push part pushing is discharged, alignment width position.

Like this, owing to only make the push part vibration, therefore the pushing paper is compared with the device of existing body vibration, can suppress the inertial mass of oscillating component very little.

If can reduce the inertial mass of oscillating component, then can quicken period of vibration, the number of times that utilizes push part to push the paper of being discharged on Width is increased.

Thus, can improve the paper alignment performance of the Width of paper.

And, in aforesaid way, described near can comprising away from mechanism: elastomeric element, to described paper side to the described push part application of force flexibly; And the position limit parts, push described push part to direction away from described paper, limit described push part to the moving of described paper side, and the predetermined moment make restriction site near or away from described paper.

In this structure, push part always by elastomeric element to the paper side application of force, therefore the restriction site by making the position limit parts near or away from paper, can make push part near or away from paper.

At this moment, because the position limit parts push push part to the direction away from paper, therefore the power that push part is applied to paper side only is the elastic force that elastomeric element produces.Therefore, for example, owing to only act on the elastic force that flexible parts produce on the push part, even therefore holding articles between paper that stacks and push part, make push part when paper side moves, also not have inappropriate masterpiece and to be used on the push part.Therefore, can prevent the danger of push part breakage.

In said structure, preferred described position limit parts by the cam part that is driven in rotation make described restriction site near or away from described paper.

So, only by making cam part rotation, just can make push part periodically approaching or away from paper.

And in aforesaid way, described antiquarian changes mechanism and can comprise: tooth bar is installed on the described moving-member along described Width with extending; Miniature gears is installed on the described Width to the position almost fixed, with described tooth bar engagement; And drive division, drive this miniature gears rotation.

In this paper aligning apparatus, mobile on Width when making the miniature gears rotation with the tooth bar of pinion by drive division, thus can regulate the position of moving-member on Width.Thus, the width position that is installed in the push part on the moving-member can be regulated, therefore the width position of push part can be regulated accordingly with the change of antiquarian.

And in aforesaid way, described moving-member and described push part can be provided with many groups along described direct of travel, and described moving-member of at least 1 group and described push part in these many groups constitute the position that can be adjusted on the described direct of travel.

Like this owing to be provided with many group moving-members and push part along the direct of travel of paper, therefore can along the direct of travel of paper on Width at many places pushing paper.

Thus, can increase number of times and scope, therefore can releasably be installed on the support component, thereby can further improve the paper alignment performance of the Width of paper to the Width pushing of paper.

And at least 1 group of organizing in moving-member and the push part constitutes the position of scalable on direct of travel more, even therefore paper follows the into length change of direction, also can tackle.

And, in said structure, in described many described moving-members of group and the described push part, the described moving-member in downstream and described push part can constitute on the stationkeeping ground of described direct of travel, and the described mobile device and the described push part of upstream side are installed on the vacuum attraction car device.

For example, in the paper delivery device for sheet of sheet-fed press, the position, downstream of the paper of discharge and the length of paper are irrelevant, for constant, are provided with the vacuum attraction car device with vacuum attraction car of braking at the upstream extremity of paper.

Vacuum attraction car device constitutes, and when the length of paper changes, can move accordingly with it, thereby regulate the position of vacuum attraction car on the paper direct of travel.

In paper aligning apparatus of the present invention, the moving-member and the push part of upstream side are installed on the vacuum attraction car device, therefore can move on the paper direct of travel along with moving of changing of the corresponding yardage of vacuum attraction car.

Like this, the moving-member of upstream side and push part are moved by the vacuum attraction car device of keeping roughly certain position relation with the upstream extremity of paper, and the push part that does not therefore need to regulate upstream side just can be positioned at upstream extremity with paper to be had on the position that the constant position concerns.

And, can omit for the position of the moving-member of regulating upstream side and push part and parts that move it and the parts of regulating.

And then the moving-member in downstream and push part are arranged in the stationkeeping on the paper direct of travel, and the downstream end that the push part in therefore downstream can be positioned at paper has on the position of constant position relation.

Therefore, for example, when moving-member and push part are 2 groups, can omit parts that move it and the parts of regulating.

Like this, the upstream end portion of paper and downstream end portion (that is, the paper of paper direct of travel central authorities both sides) are urged the parts pushing, therefore make its rotating moment in its paper can not acted on the paper.Therefore, can improve the paper alignment performance of paper width direction.

And in said structure, each described moving-member can comprise: tooth bar, change mechanism as described antiquarian, and on described Width, be installed in described moving-member with extending; Miniature gears is installed on the described Width to the position almost fixed, with described tooth bar engagement; And the common drive division that makes the common rotation of all described miniature gearss, described common drive division has the axle drive shaft that all described miniature gearss are installed, and can install movably along described axle drive shaft with the described miniature gears of described tooth bar ingear of the described moving-member that constitutes the position of scalable on described direct of travel.

In this structure, when making the axle drive shaft rotation of common drive division,, therefore, on Width, move with all tooth bars of its ingear with all miniature gears rotations that axle drive shaft fastens.Thus, all moving-members are moved on Width, therefore can regulate the width position of all push part, the change of the Width size of reply paper.

And, can install movably along axle drive shaft with the tooth bar ingear miniature gears that constitutes the moving-member that can be adjusted in the position on the direct of travel, even therefore paper direct of travel size changes, also can not be subjected to it to tackle the change of paper width direction size with influencing.

And in said structure, the shape of cross section of described axle drive shaft is preferably polygon.

So, miniature gears can move along axle drive shaft, and by polygonal jut and the rotation of axle drive shaft one, does not therefore for example need to form the such slot part of bond structure.

For example, in the paper delivery device for sheet of sheet-fed press, the pulverized powder for the greasy dirt that prevents paper, if but do not form slot part, this powder can be detained in groove, hinders miniature gears to move along axle drive shaft, and the present invention can prevent this point.

And second mode of the present invention is to use the paper delivery device for sheet of the paper aligning apparatus of above-mentioned first mode.

Paper delivery device for sheet according to the manner, owing to using the number of times to be increased in pushing paper on the Width to improve the paper aligning apparatus of paper alignment performance of the Width of paper, therefore can send to subsequent processing making paper under the state that aligns on the Width, stack paper.

And Third Way of the present invention is to use the sheet-fed press of the paper delivery device for sheet of above-mentioned second mode.

According to of the present invention first to Third Way,, therefore can be increased in the number of times of the paper of pushing discharge on the Width owing to only making the push part vibration push paper.

Thus, can improve the paper alignment performance of paper width direction.

Cubic formula of the present invention is a kind of paper aligning apparatus, has the paper alignment board of direct of travel both sides of the paper of the discharge of being configured in; And regulate the align antiquarian change mechanism of width position of board of this paper accordingly with the size of described paper, this paper alignment board is with respect to described paper crank motion periodically, the both sides of knocking described paper by this paper alignment board, with its width position that aligns, it is characterized in that, described paper alignment board, have on the movable part that is installed in described antiquarian change mechanism, carry out common reciprocatingly near away from mechanism, and carry out this large amplitude crank motion more than common big several times of reciprocating amplitude of rate of amplitude at predetermined instant.

In the paper aligning apparatus of the manner, paper alignment plate portion is positioned on paper direct of travel both sides and the position paper butt by antiquarian change mechanism.Under this state, paper alignment board by on the movable part that is installed in antiquarian change mechanism near carrying out common crank motion away from mechanism, the paper that the pushing of paper alignment board is discharged, alignment width position.

Like this,, therefore compare, can suppress the inertial mass of oscillating component very little with the device of existing body vibration owing to only making paper alignment board crank motion push paper.

If can reduce the inertial mass of oscillating component, then can quicken period of vibration, therefore can make the number of times that utilizes paper alignment board on Width, to push the paper of discharging.Thus, can improve the paper alignment performance of the Width of paper.

And, because paper alignment board carries out large amplitude crank motion more than the common big several times of reciprocating amplitude of rate of amplitude in the predetermined moment, therefore the width position of paper is bigger than the desired location, even for example when discharging greater than the deviation of common reciprocating amplitude, also can pass through this large amplitude crank motion, paper alignment board pushing paper turns back to common reciprocating amplitude range at least.

And, by the common crank motion of paper alignment board paper is alignd accurately, even therefore might be created in the paper that the Width deviation falls significantly, also can improve the paper alignment performance of paper width direction.

And in described mode, the position moving part that the described large amplitude crank motion of described paper alignment board preferably utilizes described antiquarian to change mechanism carries out.

So, need other drive elements be set separately, can prevent that therefore structure from complicating and cost increases in order to make paper alignment board large amplitude crank motion.

And the 5th mode of the present invention is to use the paper delivery device for sheet of sheet-fed press of the paper aligning apparatus of above-mentioned cubic formula.

Like this, push paper, therefore compare, can suppress the inertial mass of oscillating component very little with the device of existing body vibration because paper alignment board is vibrated.

If can reduce the inertial mass of oscillating component, then can quicken period of vibration, therefore can make the number of times that utilizes paper alignment board on Width, to push the paper of discharging.Thus, can improve the paper alignment performance of the Width of paper.

And, because paper alignment board carries out large amplitude crank motion more than the common big several times of reciprocating amplitude of rate of amplitude in the predetermined moment, therefore the Width end position of paper is bigger than the desired location, even for example when discharging with the deviation bigger than common reciprocating amplitude, also can by paper alignment board pushing paper, turn back to common reciprocating amplitude range at least by this large amplitude crank motion.

And, by the common crank motion of paper alignment board paper is alignd accurately, even therefore might be created in the paper that the Width deviation falls significantly, also can improve the paper alignment performance of paper width direction.

And in aforesaid way, the position moving part that the described large amplitude crank motion of described paper alignment board preferably utilizes described antiquarian to change mechanism carries out.

So, need other drive elements be set separately, can prevent that therefore structure from complicating and cost increases in order to make paper alignment board large amplitude crank motion.

According to cubic formula to the seven modes of the present invention, paper alignment board by moving back and forth on the movable part that is installed in antiquarian change mechanism near carrying out common crank motion away from mechanism, and carry out large amplitude crank motion more than the common big several times of reciprocating amplitude of rate of amplitude at predetermined instant, even therefore might be created in the paper that the Width upper limit of variation falls significantly, also can improve the paper alignment function of the Width of paper.

And Width paper alignment control part 165 has the function that makes electro-motor 87,133,153 actions in order to make back alignment plate 61 and preceding alignment plate 113 carry out paper alignment action.In this case, Width paper alignment control part 165 has that the action that makes electro-motor 87,133 and electro-motor 153 is synchronously controlled or multiple operation mode such as control independently.

The Width paper aligns control part 165 in order to grasp the width position of back maintaining part 55 and preceding maintaining part 101, for example moving by preceding tooth bars 145 of detection such as potentiometers.

Work to the present embodiment sheet-fed press 1 of above explanation describes.

At first, the printing action to sheet-fed press 1 describes.

The paper 9 that overlays on the feedboard for paper 11 of paper feed 3 is taken out from topmost page by page by not shown paper-feeding mechanism, is provided to printing element 5.

Be provided to of the jaw arrangement clamping of the paper 9 of printing element 5, then change into by impression cylinder 17 clampings from middle cylinder 19 by the intermediate calender rolls 19 of printing element 5.Carry out this action repeatedly,, transmit by 4 printing elements 5.

In each transfer printing unit 5, supply with water from damping device to the non-setting-out portion that is installed in forme on plate cylinder 13 peripheries, then supply with ink to the setting-out portion of forme from ink-feeding device.

Printed images on the forme that obtains thus can be transferred to blanket cylinder 15.

The printed images that is transferred on the blanket cylinder 15 is transferred on the paper 9 that sends by impression cylinder 17, carries out a kind of printing of color.

In each printing element 5, carry out this action repeatedly, can carry out colored printing.

Change jaw arrangement 29 clampings through the paper 9 of colored printing into from the impression cylinder 17 of last printing element 5 by chain type grippers 21.

Above row's paper platform 23, decontrol clamping by the paper 9 that jaw arrangement 29 transmits, it is fallen, on the row's of overlaying paper platform 23.

At this moment, print to the back side of upside paper 9 in order to prevent undried ink, when using jaw arrangement 29 to transmit, pulverized powder in advance on paper 9.

Then, the action that stacks to the paper 9 of row's paper platform 31 describes.

Regulate the position of vacuum attraction car 43, rear paper aligning apparatus 39 and Width paper aligning apparatus 35 (left side paper alignment part 47a and right side paper alignment part 47b) accordingly with the size of the paper 9 of discharging.For example, can be arranged on the position shown in the solid line of Fig. 2.

Under this state, make vacuum attraction car 43 with predetermined speed rotation, and make not shown pump work, to apply the attractive force after the adjusting.

And, make electro-motor 87,133 work.Thus, make output shaft 95,141 rotations via reductor 89,135, so eccentric cam 91,137 rotations.

During eccentric cam 91,137 rotation, move between outer fix and inner side whenever revolving when turning around the position of the outboard end of eccentric cam 91,137.This amount of movement is 2 times of offset (0.5mm), is approximately 1mm.

Like this, when the outboard end of eccentric cam 91,137 moved, restriction eccentric cam 91,137 moved on Width to the positional cycle ground of cylinder roller 81,127 medial movement.

By moving of cylinder roller 81,127, back alignment plate 67 and preceding alignment plate 113 move (with amplitude A (approximately 1mm) vibration) integratedly on Width B shown in solid line among Fig. 2 and long and short dash line.

At this moment, cylinder roller 81,127 moving laterally, the power that overcomes compression spring 85,131 by eccentric cam, 137 forces to carry out, and moving to the inside then undertaken by the power of compression spring 85,131.

Under this state, when carrying out above-mentioned presswork, the rearward end that the jaw arrangement 29 of chain type grippers 21 is decontroled the paper 9 of clampings is attracted and braking by vacuum attraction car 43, advances at leisure and falls.The front end of this paper 9 and pressing board 33 butts, making advances stops, and with the position alignment of leading section.

Simultaneously, by back alignment plate 67 and preceding alignment plate 113 pushing both sides, so the aligned in position of both sides.

And the rear end is guided by rear paper aligning apparatus 39, and stacks under the state of alignment.

Like this, owing to only make back alignment board 57 and preceding alignment board 103 vibrations push paper 9, therefore compare with the existing device of integral body (comprising dimension modifying mechanism) vibration that makes, the inertial mass of oscillating component can be suppressed very for a short time.

If can reduce the inertial mass of oscillating component, then can accelerate period of vibration, therefore can be increased in the number of times of the paper 9 that alignment plate 113 was discharged before pushing reached by back alignment plate 67 on the Width.

Thus, can improve the paper alignment performance of the Width of paper 9.

Because eccentric cam 91,137 is alignment board 103 before the direction pushing back alignment board 57 away from paper 9 reaches, therefore the power that alignment board 103 applies before paper 9 sides reach back alignment board 57 only is the elastic force of compression spring 85,131.Therefore, for example, because back alignment plate 67 and before the effect elastic force that has compression spring 85,131 etc. to produce only on the alignment plate 113, even paper 9 that therefore stacks and back alignment plate 67 and before between the alignment plate 113 holding articles and make back alignment plate 67 and before alignment plate 113 can not be to paper 9 side shiftings, do not have yet inappropriate masterpiece be used in back alignment plate 67 and before on alignment plate 113 grades.Therefore, can prevent back alignment plate 67 and preceding alignment plate 113 breakages such as grade.

And, the rear end part of paper 9 and fore-end (that is, the paper 9 central both sides of paper 9 direct of travels) by back alignment plate 67 and before alignment plate 113 pushings, therefore do not have and make moment loading that paper 9 rotates in its face on paper 9.Therefore, can improve the paper alignment performance of the Width of paper 9.

Counter-measure when then, the size of the paper 9 that print being changed describes.

As shown in Figure 2, when the paper 9 of the solid line of current operation changed to the less paper 9 of long and two-short dash line, at first, vacuum attraction car maintaining part 45 is side shifting forward, and the position of vacuum attraction car 43 is moved to the desired location shown in the long and two-short dash line.

Along with vacuum attraction car maintaining part 45 side shifting forward, move to the desired location with the rear paper aligning apparatus 39 of vacuum attraction car maintaining part 45 one.

Simultaneously, mobile holding member 163 is along axle drive shaft 151 side shifting forward.Along with moving of mobile holding member 163, back tooth bar 143 and back miniature gears 147 be side shifting forward.Along with moving of back tooth bar, back width alignment part 49 is side shifting forward, makes back alignment plate 67 be positioned at position with the rear end part fastening of new paper 9.

Like this, back width alignment part 49 moves by the vacuum attraction car maintaining part that keeps vacuum attraction car 43, this vacuum attraction car 43 is kept the position relation with the upstream extremity constant of paper 9, therefore can automatically be positioned at the paper rear end to have on the position of constant position relation.

Therefore, can omit parts that move and the parts of regulating in order to change the position of regulating back width alignment part 49 along with antiquarian.

And preceding width alignment part 51 is arranged to the stationkeeping on its paper direct of travel, therefore always is positioned at the position that has constant position relation with top of form.

Therefore, can omit for adjust back width alignment part 49 and before the position of direct of travel of width alignment part 51 and parts that move it and the parts of regulating.

Then, electro-motor 153 work, when making axle drive shaft 151 rotations via reductor 155, back miniature gears 147 and 149 rotations of preceding miniature gears.At this moment, be slidably mounted on the axle drive shaft 151 and the bight fastening and the rotation of loose back miniature gears 147 and axle drive shaft 151.

Like this, therefore axle drive shaft 151 does not need to form the such slot part of bond structure by orthohexagonal jut and the rotation of axle drive shaft 151 one.

The pulverized powder for the greasy dirt that prevents paper 9 if do not form slot part, can prevent that then this powder is trapped in the groove and hinders back miniature gears 147 to move along axle drive shaft 151.

Back miniature gears 147 and before during miniature gears 149 rotations, with tooth bar behind its ingear 143 and before tooth bar 145 on Width B, move, therefore back width alignment part 49 and before width alignment part 51 on Width, move.Thus, back alignment plate 67 and the preceding position of alignment plate 113 on Width B can be positioned at the desired location.

Like this, when making axle drive shaft 151 rotation, back tooth bar 147 and before tooth bar 149 rotations, therefore with its ingear after tooth bar 143 and before tooth bar 145 mobile on Width B.Thus, can make back width alignment part 49 and preceding width alignment part 51 mobile on Width, therefore regulate the position that back width alignment part 49 reaches the Width B of preceding width alignment part 51, can tackle the change of the Width size of paper 9.

In addition, in the present embodiment, the cross sectional shape of axle drive shaft 151 is a regular hexagon, but so long as can realize transmitting the shape of the engaging structure of rotary driving force and get final product, is not limited to regular hexagon.

For example, also can be quadrangle as shown in figure 12, so long as the above convex polygon of triangle gets final product.

And, also can be matrix polygon as shown in figure 13.

And then, also can be round section as shown in figure 14, keyway extends setting at direction of principal axis, and back miniature gears 147 is by key 165 fastenings.In this case, when on the keyway total length of axle drive shaft 151 sides, key 165 being set, can prevent effectively that powder is trapped in the keyway.

And, in the present embodiment,, but also can more than three places, align along the Width B position of direct of travel L two places alignment paper 9 of alignment plate 113 before back alignment plate 67 reaches.

And then, can improve the paper alignment performance of the Width of paper 9 by making the alignment plate slight vibration, therefore also can align at a place.

Then, other methods of operation of using Figure 15 Width paper alignment control part 165 extremely shown in Figure 19 are described.

Width paper alignment control part 165 is in electro-motor 153 work, when making axle drive shaft 151 rotations, and back miniature gears 147 reaches preceding miniature gears 49 rotations.At this moment, be slidably mounted on the axle drive shaft 151 and the bight fastening and the rotation of loose back miniature gears 147 and axle drive shaft 151.

Back miniature gears 147 and before during miniature gears 149 rotations, with tooth bar behind its ingear 143 and before tooth bar 145 on Width B, move, therefore back width alignment part 49 and before width alignment part 51 on Width, move.Thus, make back alignment plate 61 and before alignment plate 13 on the position on the Width B is positioned at shown in the solid line of Figure 15 and the cooresponding desired location of the size paper 9 of discharging.

Under this state, make vacuum attraction car 43 with predetermined speed rotation, and make not shown pump work, to apply the attractive force after the adjusting.

And Width paper alignment control part 165 makes electro-motor 87,133 and electro-motor 153 work according to the mode of operation of having set.

This mode of operation works alone electro-motor 87,133 and electro-motor 153.

Width paper alignment control part 165 drives electro-motor 87,133, and it is rotated all the time.

During electro-motor 87,133 rotations, eccentric cam 91,137 rotations, the position of the outboard end of eccentric cam 91,137 is whenever revolved to turn around and is promptly moved between outer fix and inner side.This amount of movement is 2 times of offset (0.5mm), is approximately 1mm.

Like this, when the outboard end of eccentric cam 91,137 moved, restriction eccentric cam 91,137 moved on Width to the positional cycle ground of cylinder roller 81,127 medial movement.

By moving of cylinder roller 81,127, back alignment plate 61 and preceding alignment plate 113 shown in solid line among Figure 15 and thin dashed line, integratedly on Width B with amplitude D1 slight vibration (common crank motion).Amplitude D1 is approximately 1mm.

At this moment, cylinder roller 81,127 moving laterally, the power that overcomes compression spring 85,131 by eccentric cam 91,137 forces to carry out, and moving to the inside then undertaken by the power of compression spring 85,131.

On the other hand, Width paper alignment control part 165 separate certain intervals, promptly termly or predetermined instant make electro-motor 153 to make back alignment plate 61 and before alignment plate 113 away from the direction work certain hour of paper 9, then, in order to make back alignment plate 61 and preceding alignment plate 113 is returned original position and it is worked round about.

Thus, back alignment plate 61 and before alignment plate 113 termly the position of alignment paper 9 and on the Width away from the position of this position between crank motion 1 time (large amplitude crank motion).This reciprocating amplitude D2 for example is approximately 10mm.

The size of amplitude D2 be the back alignment plate 61 that produces of electro-motor 87,133 and before about 10 times of amplitude D1 of alignment plate 113.This amplitude D2 is preferably dimensioned to be more than the several times of amplitude D1.

And the certain intervals of electro-motor 153 work for example was made as 5 seconds or 10 seconds.

This at interval or amplitude D2 can be according to the suitably configurations such as situation of the kind of the paper that uses, print out rate, row's paper.

Motion track Ka, the Kb of the position of the medial end of alignment part 61a, 61b and preceding alignment plate 113a, 113b after when Figure 16 represents to make the electro-motor 153b synchronous working of the electro-motor 153a of left side paper alignment part 47a and right side paper alignment part 47b.

Because electro-motor 87,133 works alone, therefore by electro-motor 153 away from paper 9 during, back alignment plate 61 and preceding alignment plate 113 slight vibration.

Under this state, when carrying out above-mentioned presswork, the rearward end that the jaw arrangement 29 of chain type grippers 21 is decontroled the paper 9 of clampings is attracted and braking by vacuum attraction car 43, advances at leisure and falls.The front end of this paper 9 and pressing board 33 butts, making advances stops, and with the position alignment of leading section.

Simultaneously, by back alignment plate 61 and preceding alignment plate 113 pushing both sides, so the aligned in position of both sides.

And the rear end is stacked under the state of alignment by 39 guiding of rear paper aligning apparatus.

At this moment, discharge sometimes and on Width B, depart from bigger paper 9.For example, as shown in figure 15, under big a lot of situation, be difficult to slight vibration aligned position than amplitude D1 by the back alignment plate 61 and the preceding alignment plate 113 of electro-motor 87,133 generations at the bias H that paper 9 departs from from the desired location.

In the present embodiment, in the predetermined moment, electro-motor 153 work make back alignment plate 61 and preceding alignment plate 113 carry out the crank motion of amplitude D2, therefore by this reciprocating return movement, also this paper that departs from 9 can be pushed back the inboard.

At this moment because back alignment plate 61 and before alignment plate 113 carry out slight vibration, while therefore knock paper 9 it is pushed back the width position of easier alignment paper 9.

And, when paper 9 enters the scope of amplitude D1 of slight vibration, can may on Width, depart from the paper that falls significantly even therefore exist by align the accurately position of paper 9 of this slight vibration, also can improve the paper alignment performance of the Width of paper.

Like this, only make back alignment board 57 and preceding alignment board 103 vibrations push paper 9, therefore compare with the existing device that integral body (comprising antiquarian change mechanism) is vibrated, the inertial mass of oscillating component can be limited very for a short time.

If can reduce the inertial mass of oscillating component, then can quicken period of vibration, therefore can increase the number of times that on Width, pushes the paper 9 of discharging by back alignment plate 61 and preceding alignment plate 113.

Thus, can improve the paper alignment performance of the Width of paper 9.

In addition, in the present embodiment, the electro-motor 153a of left side paper alignment part 47a is synchronoused working with the electro-motor 153b of right side paper alignment part 47b, but also can make it asynchronous as shown in figure 17, in different moment work.

So, on the other hand, for example as shown in figure 15, when departing from bigger paper 9 on the left of back alignment plate 61a and preceding alignment plate 113a knock, back alignment part 61b and preceding alignment plate 113b slight vibration are near the desired location, therefore can prevent that paper 9 is bigger in the right side deviation.

And, in the present embodiment, electro-motor 87,133 and electro-motor 153 independent operation, but also can run-in synchronism.

In this case, for example as shown in figure 18, the peak value of the slight vibration of the peak value of amplitude D2 of electro-motor 153 and electro-motor 87,133 is as one man turned round.

So, for example back alignment plate 61 and before the separating distance of alignment plate 113 bigger, therefore by electro-motor 153 correspondingly reduced back maintaining part 55 and before the amount of movement of maintaining part 101.

And, for example as shown in figure 19, the mode run-in synchronism that electro-motor 97,133 stops in the time of also can working with electro-motor 153.

So, do not needing to carry out to stop electro-motor 87,133 during the aligned in position of paper 9, thereby can correspondingly save power.

In addition, in the following description, the structure that left side paper alignment part 201a and right side paper alignment part 201b have mutual line symmetry, therefore following structure to left side paper alignment part 201a describes, and the short of special reason of explanation of right side paper alignment part 201b is as far as possible with its omission.In addition, for left side paper alignment part 201a and right side paper alignment part 201b, distinguish at label end interpolation " a ", " b ".That is, " a " expression is position or the parts of left side paper alignment part 201a, and " b " expression is position or the parts of right side paper alignment part 201b.And in the explanation afterwards, annotate under the situation of difference left side paper alignment part 201a and right side paper alignment part 201b a, b distinguish; Under the situation about distinguishing especially, do not omit a, b and only represent each position and parts with label.

Left side paper alignment part 201a has as the back alignment part 220 of width alignment part and preceding alignment part 240.Back alignment part 220 and preceding alignment part 240 dispose successively along the direct of travel L of paper 9, that is, back alignment part 220 is located at upstream side (rear side), and preceding alignment part 240 is located at downstream (front side).The position of the Width B of the rearward end side of back alignment part 220 alignment paper 9, the position of the Width B of preceding on the other hand alignment part 240 alignment leading section sides.And then, as shown in figure 22, left side paper alignment part 201a has the dimension modifying mechanism 280 as antiquarian change mechanism, and this dimension modifying mechanism 280 changes the position on the Width B of this back alignment part 220 and preceding alignment part 240 corresponding to the size of the Width B of paper 9.

At this, the preceding alignment part 240b of the back alignment part 220b of the back alignment part 220a of left side paper alignment part 201a and right side paper alignment part 201b, the preceding alignment part 240a of left side paper alignment part 201a and right side paper alignment part 201b is equivalent to 1 pair of width alignment part of the present invention respectively.That is, the Width paper aligning apparatus 200 of present embodiment is provided with 2 groups of 1 pair of width alignment part of the present invention along direct of travel L.And, back alignment part 220a and back alignment part 220b, in the rearward end side of paper 9, broad ways B disposes relatively in the direct of travel both sides of paper 9; On the other hand, preceding alignment part 240a and preceding alignment part 240b, in the toe lateral of paper 9, broad ways B disposes relatively in the direct of travel both sides of paper 9.

In addition, in the explanation of following Figure 23 to Figure 28, back alignment part 220 and preceding alignment part 240 have roughly line symmetrical structure mutually, and therefore the structure to preceding alignment part 240 is elaborated, and the short of special reason of the explanation of back alignment part 220 is as far as possible with its omission.Wherein, back alignment part 220 as the back alignment plate 221 of aftermentioned paper align unit and shorter slightly than the preceding alignment plate 241 and the holding plate 243 of preceding alignment part 240 as the length of holding plate 223 on direct of travel L of holding member.

As Figure 23, shown in Figure 28, preceding alignment part 240 has preceding alignment plate 241 as the paper align unit, as the swing part 242 of swing part, as the holding member 43 of holding member.It is the tabular of long limit that preceding alignment plate 241 forms along the limit of direct of travel L.Holding plate 243 forms the tabular of L font roughly, place and fixing swing part 242 at the face of vertical upside, on the other hand, on the face of vertical downside, fix described later before tooth bar 282.Swing part 242 has leaf spring 244 (spring members) as force application part, as the eccentric cam mechanism 245 of wobble drive mechanism.

As shown in figure 24, leaf spring 244 has: be fixed on base end part 246 on the holding plate 243, be located at vertical (paper 9 stack direction) reflex part 247 of downside and the leading section 248 of going back to the vertical upside via reflex part 247 of base end part 246.Base end part 246 is fixed on from the outstanding leaf spring installation portion 249 of the lower surface of holding plate 243.And leaf spring 244 extends setting at the leading section 248 that reflex part 247 turns back to paper 9 sides above vertical.That is, the cross sectional shape of the short side direction of leaf spring 244 forms the roughly shape of J type.

Before alignment plate 241, can with these paper 9 Width sidepiece butts be fixed on the face of paper 9 sides of leading section 248 of leaf spring 244, and be supported on the holding plate 243 by this leaf spring 244.Leaf spring 244 can be that pivot point flexibly rotates with the reflex part 247 of vertical bottom, and preceding alignment plate 241 can freely swing on Width B as the swing fulcrum with the apex portion of the reflex part 247 of this leaf spring 244.Therefore, preceding alignment plate 241 is provided with the swing fulcrum at the vertical downside, and it is alignment plate 241 before the center is supported on Width B with freely swinging that leaf spring 244 makes preceding alignment plate 241 swing fulcrum with this, and can be to the paper 9 side application of forces.To these preceding alignment plate 241 application of forces, effect has the power that promotes paper 9 to this leaf spring 244 on preceding alignment plate 241 to paper 9 directions.At this, preceding alignment plate 241 forms along the limit of direct of travel L as mentioned above as the rectangular plate shape on long limit, so the swing fulcrum of the apex portion of reflex part 247 forms along the axis of oscillation of the level of direct of travel L.

By above-mentioned base end part 246 be fixed on the holding plate 243, on the leading section 248 that reflex part 247 turns back, be provided with before alignment plate 241, before can being implemented in the bottom of alignment plate 241 the swing fulcrum is set, can be supported on with freely swinging this preceding alignment plate 241 the upper end structure and to the structure of paper 9 sides to preceding alignment plate 241 application of forces.

As shown in figure 25, preceding alignment plate 241 is formed with breach 254 in the vertical bottom.And preceding alignment part 240 has confinement plate 255 in this breach 254.Confinement plate 255 forms tabular, is fixed on the holding plate 243 in the swing fulcrum side of preceding alignment plate 241.The plate-shaped member that confinement plate 255 is and preceding alignment plate 241 splits ground forms, the face of paper 9 sides roughly aligns with the face of paper 9 sides of the vertical bottom of preceding alignment plate 241, can with the Width sidepiece butt of paper 9.And as mentioned above, preceding alignment plate 241 is supported on the holding plate 243 by leaf spring 244, can move with respect to holding plate 243 thus; On the other hand, confinement plate 255 is fixed on the holding plate 243, can not move with respect to this holding plate 243 thus.

As Figure 23, shown in Figure 26, eccentric cam mechanism 245 has swing electro-motor 250, eccentric cam 251, connecting rod 252 and the cam lateral bracket 253 as motor.Cam lateral bracket 253 is fixed on the face of vertical upside of holding plate 243.But swing electro-motor 250 driven in rotation, and the one end has output shaft 256.Swing is installed on the cam lateral bracket 253 with electro-motor 250, and its output shaft 256 is inserted in the cam lateral bracket 253.

Eccentric cam 251 is located at swing with on the output shaft 256 of electro-motor 250.Eccentric cam 251 is rotatably supported by two antifriction-bearing boxs 257 in the cam lateral bracket 253.Eccentric cam 251 forms the shape of stacked a plurality of cylinders, and its central axis is positioned at the position of departing from scheduled volume δ (for example 0.5mm) abreast with the rotation axis of electro-motor 250 with swing.

One end side of connecting rod 252 is provided with eccentric cam 251, and the other end side is provided with preceding alignment plate 241.One end side of connecting rod 252 runs through the sidewall of cam lateral bracket 253, forms to insert mouth 258 in this cam lateral bracket 253.Connecting rod 252 has antifriction-bearing box 259 in this insertion mouth 258, insert the eccentric part of eccentric cams 251 by this antifriction-bearing box 259.Connecting rod 252 is connected by this antifriction-bearing box 259 relatively with eccentric cam 251 with rotating freely.

And, the connecting portion 260 of alignment plate 241 and eccentric cam mechanism 245 before the other end side of connecting rod 252 is provided with and connects.As Figure 26, shown in Figure 27, connecting portion 260 has slotted hole 261 as recess, as the pin 262 and the paper alignment plate lateral bracket 263 of protuberance.Paper alignment plate lateral bracket 263 is fixed in the back side (back side of the face of paper 9 sides) of the leading section 248 of leaf spring 244.Slotted hole 261 is formed at the other end side of connecting rod 252, promptly with the end of the opposition side of the end that is connected with eccentric cam 251.Slotted hole 261 broad ways B are the application of force direction setting of leaf spring 244.Pin 262 is installed on the paper alignment plate lateral bracket 263 regularly, and inserts this slotted hole 261.Then, there is predetermined gap in the application of force direction along leaf spring 244 between this slotted hole 261 and the pin 262.Therefore, before alignment plate 241 form following structure: be connected with the connecting rod 252 of eccentric cam mechanism 245 via leaf spring 244 and paper alignment plate lateral bracket 263 with connecting portion 260, and on Width B, buffer zone arranged according to gap along the application of force direction of slotted hole 261 and pin 262.Its result is, for example, even the paper 9 that falls from chain type grippers 21 drops on the position of departing from significantly, perhaps accompany foreign matter etc. between paper 9 on the row's of overlaying paper platform 23 and the preceding alignment plate 241, be applied with under the situation of excessive load on alignment plate 241 and the leaf spring 244 before making, the leading section 248 of preceding alignment plate 241 and leaf spring 244 also can pass through along the gap of the application of force direction of slotted hole 261 and pin 262, withdraw to direction, prevent that alignment plate 241 and leaf spring 244 forward from applying the inappropriate power above the elastic force of this leaf spring 244 away from paper 9.

To above-mentioned such eccentric cam mechanism 245 that constitutes, by driving output shaft 256 rotations of swing with electro-motor 250, eccentric cam 251 also rotates jointly with this output shaft 256, thus connecting rod 252 with corresponding to offset (scheduled volume δ) apart from broad ways B crank motion.Then, eccentric cam mechanism 245 is by the crank motion of connecting rod 252 broad ways B, before can making the top of alignment plate 241 and the paper aligned position of paper 9 butts (among Figure 24 shown in the solid line) and away from the position of readiness of paper 9 (among Figure 24 shown in the dotted line) between reciprocally swinging.More particularly, eccentric cam mechanism 245, by eccentric cam 251 rotations, connecting rod 252 broad ways B move to the direction away from paper 9, shown in the dotted line of Figure 24, to leading section 248 and the preceding alignment plate 241 away from the direction stretching leaf spring 244 of paper 9, therefore, the leading section 248 of leaf spring 244 is that the center is to rear side (opposition side of paper 9) bending with the swing fulcrum of the apex portion that is positioned at reflex part 247.Thus, the vertical upper end of paper alignment plate 241 is that middle mind-set is rotated away from a side of paper 9 with the leading section 248 of leaf spring 244 with this swing fulcrum.Then, be further rotated by eccentric cam 251, connecting rod 252 broad ways B are to the side shifting near paper 9, and the leading section 248 of leaf spring 244 is that paper 9 sides are returned at the center with the swing fulcrum.Thus, the vertical upper end of preceding alignment plate 241 is that middle mind-set paper 9 sides are rotated with the leading section 248 of leaf spring 244 with this swing fulcrum.Therefore, the top of alignment plate 241 was along the Width swing of paper 9 before swing part 242a can make.

At this moment, preceding alignment plate 241 serves as a swing spot wobble by the apex portion with reflex part 247, and its swinging distance is elongated in vertical upper end side, and side shortens in the bottom, and near the lowest end the swing fulcrum is almost nil.And, before alignment plate 241 near the position of paper 9, be the position of the preceding alignment plate 241 of connecting rod 252 when being positioned at the most close paper 9 sides, by the dimension modifying mechanism 280 of following explanation Width length setting, promptly be set in the position that can not run into the sidepiece of paper 9 according to paper 9.

As shown in figure 22, dimension modifying mechanism 280 has as the back tooth bar 281 of tooth bar and preceding tooth bar 282, electro-motor 286 and the reductor 287 used as the back miniature gears 283 of miniature gears and preceding miniature gears 284, axle drive shaft 285, as the change Width of drive division.

And then control setup 300 is electrically connected with input/output unit 303 and sampling switch 304.Input/output unit 303 is imported indication by the operator when sheet-fed press 1 running, the operative condition of sheet-fed press 1 is shown to the operator, has guidance panel and monitoring device etc.By input/output unit 303, for example be used for the default indication of the size of default paper 9 according to operator's operation input, the handling part 301 of control setup 300 is according to should defaultly indicating, the driving of control vacuum attraction car device 37 and dimension modifying mechanism 280 can move to and the cooresponding desired location of the size of paper 9 back alignment part 220a, back alignment part 220b, preceding alignment part 240a and preceding alignment part 240b.Sampling switch 304 can send to sampled signal control setup 300 after being set to ON by operator's operation.And in the present embodiment, input/output unit 303 and sampling switch 304 splits constitute, and input/output unit 303 also can be used as test section of the present invention.

This control setup 300 is set to sampling switch 304 ON in the operation by the operator, generates under the situation of sampled signal, when receiving the sampled signal from sampling switch 304, drive retaining paper and make axle 41 rotations with electro-motor 305, shown in the dotted line of Figure 20, paper stopping part spare 33 is fallen down to the downstream direction of direct of travel L, and this paper stopping part spare 33 remains on open position.Afterwards, the electro-motor 286a of the change of control setup 300 the controlling dimensions 280a of mechanism, 280b, the driving of 286b, make holding plate 223a, 223b, 243a, 243b (with reference to Figure 22) broad ways B away from paper 9, make back alignment part 220a, back alignment part 220b, preceding alignment part 240a and preceding alignment part 240b respectively away from paper 9 preset distances (for example about 5mm).Then, when control setup 300 is set to OFF in the operation by the operator with sampling switch 304, drive retaining paper and make axle 41 rotations with electro-motor 305, paper stopping part spare 33 is erected to the updrift side of direct of travel L, this paper stopping part spare 33 is maintained in its closed position, the driving of control electro-motor 286a, 286b, make holding plate 223a, 223b, 243a, 243b (with reference to Figure 22) broad ways B near paper 9, make back alignment part 220a, back alignment part 220b, preceding alignment part 240a and preceding alignment part 240b return-to-home position.

And then, the driving of this control setup 300 control swing electro- motor 130a, 130b, 250a, 250b, each back alignment plate 221a, the 221b of alignment part 220a, back alignment part 220b, preceding alignment part 240a and preceding alignment part 240b and the top of preceding alignment plate 241a, 241b and the time of paper 9 butts differ from one another the step after setting for.

Then, the sheet-fed press 1 of above-mentioned explanation and the action of Width paper aligning apparatus 200 are described.At first, when importing the size of paper 9 by input/output unit 303 by the operator, dimension information based on the paper of importing 9, electro-motor 286a, the 286b of control setup 300 control vacuum attraction car devices 37 and dimension modifying mechanism 280, vacuum attraction car 43, rear paper aligning apparatus 39, back alignment part 220a, back alignment part 220b, preceding alignment part 240a and preceding alignment part 240b are moved to and the cooresponding desired location of the size of paper 9 (for example, position shown in the solid line of Figure 21).Then, control setup 300 begins to comprise the driving of swing with each drive division of paper feed 3, Printing Department 2 and the paper delivery device for sheet 7 of electro- motor 230a, 230b, 250a, 250b after receiving the printing commencing signal by input/output unit 303.

The paper 9 that stacks on the feedboard for paper 11 of paper feed 3 is begun to take out one by one from topmost by paper-feeding mechanism 6, offers the printing element 5 of Printing Department 2.The paper 9 that offers printing element 5 is replaced clamping successively by the impression cylinder 17 of each printing element 5 and the jaw arrangement (not shown) of intermediate calender rolls 19, is transmitted ink in the transfer printing successively in its way by each printing element 5.

In each printing element 5, provide water by the non-setting-out portion of the forme of damping device (not shown) on the periphery that is installed in plate cylinder 13, then provide ink to the setting-out portion of forme by ink-feeding device (not shown).Printed images on the forme that obtains thus is transferred on the blanket cylinder 15.The printed images that is transferred on the blanket cylinder 15 is transferred on the paper 9 that ships by impression cylinder 17, carries out a kind of printing of color.On each printing element 5, repeat this process, carry out colored printing.

The paper 9 that has carried out colored printing changes grippers 15a clamping by chain type grippers 21 into by the impression cylinder 17 of last printing element 5.Decontroled clamping, fallen the top of the row's of overlaying paper platform 23 above row's paper platform 23 by the paper 9 that grippers 15a transmits.At this moment, print to the back side of the paper 9 of upside in order to prevent undried printing ink, when transmitting by grippers 15a on paper 9 pulverized powder in advance.

Therebetween, in paper delivery device for sheet 7, vacuum attraction car 43 is with predetermined speed rotation, and the work of the attraction portion (not shown) by pump etc., produces predetermined attractive force.Then, by swing electro- motor 130a, 130b, 250a, 250b driven in rotation, each back alignment plate 221a, the 221b of back alignment part 220a, 220b and preceding alignment part 240a, 240b and the vertical upper end of preceding alignment plate 241a, 241b are center broad ways B swing with the swing fulcrum of vertical bottom side.

Under this state, as mentioned above, the rearward end of being decontroled the paper 9 of clamping by the grippers 15a of chain type grippers 21 is attracted and braking by vacuum attraction car 43, slowly advances and falls.Then, these paper 9 front ends and paper stopping part spare 33 butts stop to advance, and the position alignment of leading section.Simultaneously, paper 9, end side is by back alignment plate 221a and the back alignment plate 221b both sides pushing from Width B thereafter, and its leading section side is by preceding alignment plate 241a and the preceding alignment plate 241b both sides pushing from Width B, so the aligned in position of Width B.Then, the rear end of paper 9 is by rear paper aligning apparatus 39 guiding and aim at, and paper 9 overlays on row's paper platform 23 with the state of relative direct of travel L and Width B alignment as shown in figure 24.

At this moment, for example, preceding alignment plate 241a, only vertical top serves as a swing spot wobble with the apex portion of the reflex part 247a of vertical downside, therefore swing part 242a can will should be restricted to Min. by preceding alignment plate 241a swing part, so inertial mass reduces, the oscillation period of alignment plate 241 before can accelerating.Therefore, can increase the pushing number of times of paper 9 on Width B, improve the paper alignment performance of paper falling.And then, preceding alignment plate 241a serves as a swing spot wobble with the apex portion of reflex part 247a, its swinging distance with fall process in the vertical upper end side that contacts of paper 9 elongated in, the bottom side that contacts with the paper 9 that stacks on row's paper platform 23 shortens, therefore can align effectively and fall the width position of the paper 9 in the process, and can prevent from the paper 9 on the row's of overlaying paper platform 23 is applied unnecessary vibration, thereby prevent the damage of this paper 9.

And, for example, the vertical Nogata of preceding alignment plate 241a is provided with confinement plate 255a to the bottom, when preceding alignment plate 241a relatively moves with respect to holding plate 243, therefore confinement plate 255a can not move relative to this holding plate 243, can keep arranging the position on the Width B of the paper 9 that stacks on the paper platform 23 effectively.

And, as mentioned above, back alignment plate 221a, 221b and preceding alignment plate 241a, 241b formation follows into, and the limit of direction L is the rectangular plate shape on long limit, therefore alignment plate 221a after, 221b and preceding alignment plate 241a, the face of the Width sidepiece butt of 241b and paper 9 is very wide, the Width of paper 9 so can easily align, because the swing fulcrum of the apex portion of reflex part 247 follows the into axis of oscillation of the L shaped one-tenth level of direction, therefore alignment plate 221a after, 221b and preceding alignment plate 241a, 241b oscillating quantity in the horizontal direction is constant, and therefore the contact condition with paper 9 can keep stable in the horizontal direction.

And then, because control setup 300 control swing electro-motor 130a, 130b, 250a, the driving of 250b, set back alignment part 220a for, back alignment part 220b, each back alignment plate 221a of preceding alignment part 240a and preceding alignment part 240b, 221b and preceding alignment plate 241a, the time of the top of 241b and paper 9 butts differs from one another the step, so alignment plate 221a after 4,221b and preceding alignment plate 241a, the oscillation period of 241b is also inconsistent, even, also this paper 9 can be focused on the desired location so the lowering position of the paper 9 that falls from chain type grippers 21 has deviation.

And, in this Width paper aligning apparatus 200, be provided with back alignment part 220a and back alignment part 220b and preceding alignment part 240a and these two groups of width alignment part of preceding alignment plate 240b along direct of travel L, therefore back alignment part 220a and back alignment part 220b are in the width position of the rearward end side alignment paper 9 of paper 9, before alignment part 240a and preceding alignment plate 240b at the width position of the leading section side alignment paper 9 of paper 9, therefore do not have and make moment loading that paper 9 rotates in its face on paper 9.

And control setup 300 receives when stopping printing signal from input/output unit 303, stops to comprise the driving of swing with each drive division of paper feed 3, Printing Department 2 and the paper delivery device for sheet 7 of electro- motor 130a, 130b, 250a, 250b.

At this, in sheet-fed press 1 operation process, when the paper 9 that stacks from row's paper platform 23 extracted the sample of the paper 9 after printing, this control setup 300 was when sampling switch 304 receives sampled signal, drive retaining paper with electro-motor 305, paper stopping part spare 33 is remained on open position.Afterwards, the electro-motor 286a of the change of control setup 300 the controlling dimensions 280a of mechanism, 280b, the driving of 286b, make back alignment part 220a, back alignment part 220b, preceding alignment part 240a, preceding alignment part 240b respectively temporarily away from paper 9 preset distances, swing to direct of travel L downstream by paper stopping part spare 33 thus and form the gap, when the paper 9 that stacks is taken a sample, prevent that paper 9 from being tangled by each back alignment plate 221a, 221b and preceding alignment plate 241a, 241b.

Action when then, the size of the paper 9 that print being changed describes.As shown in figure 21, when the paper 9 as the solid line of current operation changed over the less paper 9 of long and two-short dash line, at first, vacuum attraction car support portion 45 is side shifting forward, makes the position of vacuum attraction car 43 move to the desired location shown in the long and two-short dash line.And, along with this vacuum attraction car support portion 45 to the moving of front side, move to the desired location with the rear paper aligning apparatus 39 of vacuum attraction car support portion 45 one.Simultaneously, mobile holding member 292a, 292b are along axle drive shaft 285a, 285b side shifting forward.Move moving of holding member 292a, 292b by this, back tooth bar 281a, 281b and back miniature gears 283a, 283b be side shifting forward.And along with moving of back tooth bar 281a, 281b, preceding alignment part 220a, 120b be side shifting forward, back alignment plate 221a, 221b be configured to can with the position of the rear end part butt of new paper 9.

Like this, back alignment part 220a, 120b move by vacuum attraction car support portion 45, wherein this vacuum attraction car support portion 45 is used to keep keeping with the upstream extremity of paper 9 the vacuum attraction car 43 of constant position relation, therefore can automatically be positioned at the position that has constant position relation with the rear end of paper 9.Therefore, can omit parts that move it for the position of regulating back alignment part 220a, 120b according to the dimension modifying of paper 9 and the parts of regulating.And, preceding alignment part 240a and before alignment part 240b be arranged in the stationkeeping of paper 9 direct of travel L, the front end that therefore always is positioned at paper 9 has on the position of constant position relation.Therefore can omit in order to regulate back alignment part 220a, 220b and preceding alignment part 240a, 240b in the position of direct of travel and parts that move it and the parts of regulating.

Then, electro- motor 286a, 286b work, when making axle drive shaft 285a, 285b rotation via reductor 287a, 287b, back miniature gears 283a, 283b and preceding miniature gears 284a, 284b rotation.At this moment, being slidably mounted in bight that axle drive shaft 285a, 285b last and loose back miniature gears 283a, 283b and cross sectional shape roughly be orthohexagonal axle drive shaft 285a, 285b fastens and rotates.

When back miniature gears 283a, 283b and preceding miniature gears 284a, 284b rotation, mobile on Width B with tooth bar 281a, 281b behind its ingear and preceding tooth bar 282a, 28b, alignment part 240b moved on Width B before therefore back alignment part 220a, 120b and preceding alignment part 240a reached.Thus, can make back alignment plate 221a, 221b and before position on the Width B of alignment plate 241a, 241b be positioned on the desired location.

Like this, in the Width paper aligning apparatus 200 of present embodiment, has back alignment part 220a, 120b and preceding alignment part 240a, 240b, the direct of travel L both sides of the paper 9 after it is located at and prints, when stacking paper 9, the align position of Width B of this paper 9, back alignment part 220a, back alignment part 220b, before alignment part 240a and before alignment part 240b has respectively: the top on vertical can be that the swing fulcrum freely swings with the bottom, and can with the back alignment plate 221a of the Width B sidepiece butt of paper 9,221b and preceding alignment plate 241a, 241b, can make back alignment plate 221a, 221b and preceding alignment plate 241a, 241b is to the swing part 222a of the Width B of paper 9 swing, 222b, 242a, 242b.

Therefore, for example, in preceding alignment part 240a, preceding alignment plate 241a, only swing as the swing fulcrum with the vertical bottom on top, swing part 242a can be suppressed to Min. with the part of swinging among the alignment plate 241a before being somebody's turn to do thus, so inertial mass reduces the oscillation period of alignment plate 241a before can accelerating.Therefore, can be increased in the number of times that Width B goes up pushing paper 9, improve the paper alignment performance of paper 9.And then, before alignment plate 241a swinging distance with fall process in the vertical upper end side that contacts of paper 9 elongated in, the bottom side that contacts with the paper 9 that stacks on row's paper platform 23 shortens, therefore can align effectively and fall the width position of the paper 9 in the process, and can prevent from the paper 9 on the row's of overlaying paper platform 23 is applied unnecessary vibration, prevent the damage of this paper 9.Consequently, can realize the raising of paper alignment performance and prevent the damage of paper 9, promptly prevent printing trouble simultaneously.

And then in the Width paper aligning apparatus 200 of present embodiment, back alignment plate 221a, 221b, 241a, 241b form tabular, and the swing fulcrum is along the axis of oscillation of the L shaped one-tenth level of direct of travel.Therefore, back alignment plate 221a, 221b and before among alignment plate 241a, the 241b, with the face of the Width sidepiece butt of paper 9 can guarantee bigger, so position of the Width B of the paper 9 that can more easily align.And then, the swing fulcrum is along the axis of oscillation of the L shaped one-tenth level of direct of travel, therefore the oscillating quantity of back alignment plate 221a, 221b and preceding alignment plate 241a, 241b is constant in the horizontal direction, stable in the horizontal direction with the contact condition of paper 9, therefore can make the in stable condition of paper 9, therefore can suppress the damage of this paper 9 effectively.

And then, in the Width paper aligning apparatus 200 of present embodiment, for example, in preceding alignment part 240a, swing part 242a have make before alignment part 241a top and the paper aligned position of paper 9 butts and away from the position of readiness of paper 9 between the 245a of eccentric cam mechanism of reciprocally swinging.Therefore, make top reciprocally swinging between paper aligned position and position of readiness of preceding alignment plate 241a by the 245a of eccentric cam mechanism, therefore on the top of this preceding alignment plate 241a from the paper aligned position when position of readiness moves, make the paper that on Width B, falls 9 with departing from suitable stacked position with should before behind the top butt of alignment plate 241a, move to the paper aligned position from position of readiness on the top of alignment plate 241a before being somebody's turn to do, and this paper 9 can be back into the appropriate location on the Width B thus.

And then, in the Width paper aligning apparatus 200 of present embodiment, for example in preceding alignment part 240a, the 245a of eccentric cam mechanism has: but the swing of driven in rotation is provided with connecting rod 252a that eccentric cam 251a and the other end side be provided with preceding alignment plate 241a from swing with stagger abreast eccentric cam 251a, the end side of predetermined value delta of the rotation axis of electro-motor 250a with electro-motor 250a, central axis position.Therefore, by drive swing with electro-motor 250a, make eccentric cam 251a rotation, make the reciprocating simple structure of connecting rod 252a, the top that makes preceding alignment plate 241a and the paper aligned position of paper 9 butts and away from the position of readiness of paper 9 between reciprocally swinging.

And then, in the Width paper aligning apparatus 200 of present embodiment, for example, in preceding alignment part 240a, have connecting portion 260a, this connecting portion 260a has: alignment plate 241a and the 245a of eccentric cam mechanism and be located at slotted hole 261a on the connecting rod 252a of the 245a of eccentric cam mechanism before connecting; And the paper alignment plate lateral bracket 263a that is located at preceding alignment plate 241a side goes up and inserts the pin 262a among this slotted hole 261a, swing part 242 has can be to the leaf spring 244a of paper 9 sides to the top application of force of this preceding alignment plate 241a, and slotted hole 261a and pin 262a have the gap along its application of force direction.Therefore, being provided with can be with the top of the preceding alignment plate 241a leaf spring 244a to the paper 9 side application of forces, and before connection, be provided with slotted hole 261a on the connecting portion 260a of alignment plate 241a and the 245a of eccentric cam mechanism and have the pin 262a that is inserted into gap in the slotted hole 261a along application of force direction, thus by leaf spring 244a always to paper 9 sides the time to the preceding alignment plate 241a application of force, alignment plate 241a before being somebody's turn to do, with on the connecting portion 260a along the gap of the application of force direction of slotted hole 261a and pin 262a accordingly, on Width B, form buffer zone.Its result is, for example, even be applied with under the situation of excessive load on preceding alignment plate 241a and the leaf spring 244a, the leading section 248a of preceding alignment plate 241a and leaf spring 244a also can be by the gap along application of force direction of slotted hole 261a and pin 262a, withdraw to direction away from paper 9, therefore prevent that alignment plate 241a forward from applying the inappropriate power above the elastic force of this leaf spring 244a, the breakage of alignment part 240a before can preventing.

And then, in the Width paper aligning apparatus 200 of present embodiment, for example, the holding plate 243a that comprises alignment plate 241a and swing part 242a before being provided with in preceding alignment plate 40a has as the leaf spring 244a of force application part: be fixed on base end part 246a on the holding plate 243a, be located at this base end part 246a the vertical downside reflex part 247a and via reflex part 247a go back to the vertical upside and be provided with before the leading section 248a of alignment plate 241a.Therefore, base end part 246a be fixed on holding plate 243a go up, on the leading section 248a of the leaf spring 244a that reflex part 247a turns back, be provided with before alignment plate 241a, the vertical bottom of alignment plate 241a is provided with structure that swing fulcrum, this preceding alignment plate 241a top can support with freely swinging and to the structure of paper 9 sides to the preceding alignment plate 241a application of force before can being implemented in simultaneously thus, therefore number of components can be reduced, and the high efficiency in space can be realized being provided with compact design.

And then, in the Width paper aligning apparatus 200 of present embodiment, for example in preceding alignment plate 240a, has confinement plate 255a, this confinement plate 255a and preceding alignment plate 241a split, can be connected to the Width sidepiece of paper 9, and be fixed on the holding plate 243a in the swing fulcrum side of preceding alignment plate 241a.Therefore, on preceding alignment plate 241a, be provided with confinement plate 255a in the vertical bottom, when preceding alignment plate 241a relatively moves with respect to holding plate 243a, confinement plate 255a can not move relative to this holding plate 243a, therefore the position of paper 9 on Width B on the row's of overlaying paper platform 23 be can keep effectively, paper 9 ground, alignment more fitly therefore can not damaged.

And then, in the Width paper aligning apparatus 200 of present embodiment, have: be located at holding plate 223a, 223b, 243a, 243b last and back tooth bar 281a, 281b that extend along Width B and before tooth bar 282a, 282b; With back tooth bar 281a, 281b and before behind the tooth bar 282a, 282b ingear miniature gears 283a, 283b and before miniature gears 284a, 284b; And drive back miniature gears 283a, 283b and before electro-motor 286a, the 286b of miniature gears 284a, 284b rotation, also have make holding plate 223a, 223b, 243a, 243b with back tooth bar 281a, 281b and before tooth bar 282a, 282b along the 280a of dimension modifying mechanism, 280b that Width B moves.Therefore, when making back miniature gears 283a, 283b and preceding miniature gears 284a, 284b rotation by electro-motor 286a, 286b, with back miniature gears 283a, 283b and before behind the miniature gears 284a, 284b ingear tooth bar 281a, 281b and before tooth bar 282a, 282b on Width B, move, thereby can regulate holding plate 223a, 223ab, 243a, the 243b position on Width B.Thus, can adjust the width position that the back alignment plate 221a, the 221b that are installed on holding plate 223a, 223b, 243a, the 243b reach preceding alignment plate 241a, 241b, therefore can regulate the width position of back alignment plate 221a, 221b and preceding alignment plate 241a, 241b corresponding to the dimension modifying of paper 9.

And then, in the Width paper aligning apparatus 200 of present embodiment, have the control setup 300 of driving of controlling dimension the change 280a of mechanism, 280b and the sampling switch 304 that when paper 9 is taken a sample, sampled signal can be sent to control setup 300, when control setup 300 receives sampled signal, controlling dimension the change 280a of mechanism, 280b, make back alignment plate 221a, 221b and before alignment plate 241a, 241b with holding plate 223a, 223b, 243a, 243b along Width B away from paper 9.

Therefore, make back alignment part 220b, preceding alignment part 240a and before alignment part 240b respectively temporarily from paper 9 away from preset distance, thus when the paper 9 that stacks is taken a sample, can prevent paper 9 by each back alignment plate 221a, 221b and before alignment plate 241a, 241b tangle, therefore can prevent the sample damage of the paper 9 extracted out.
