Description
Technical area
The present invention relates to a kind of storage paper roll of perfecting press, particularly relate to when the paper supporting surface is shunk, the leading section of the comb tooth-like part of rear supporter than the position of living paper by the grippers rank also to the improvement of the storage paper roll of the outstanding structure in front portion.
Background technology
Be the example that to carry out the sheet-fed press of printed on both sides shown in Fig. 8.This perfecting press is made of with row paper portion 3 and Printing Department 2 paper feed part 1, and Printing Department 2 has two printing elements 4,5.And,, be provided with the paper transfer unit 4,5 of two printing elements for the pressure roller 7 from the pressure roller 6 of the printing element 4 of upstream side to the printing element 5 in downstream transmits sheet-feds.Perfecting press shown in Figure 8 can switch to and is printed on one side and printed on both sides, when printed on both sides, after the face by printing element 4 printings one side of upstream side, by the face of the remaining opposite side of printing element 5 printings in downstream.Specifically be exactly to print the face of a side, by the face of the printing element 5 dichromatisms printing opposite side in downstream by printing element 4 dichromatisms of upstream side.In addition, when being printed on one side, be total to the four-color process single face by two printing elements 4,5.
The sheet-fed that printing element 4 by upstream side is printed is delivered to the paper transfer unit of the printing element 5 in downstream like this, has transfer cylinder 8 (the 1st transfer cylinder), storage paper roll 9 (the 2nd transfer cylinder) and counter-rotating cylinder 10 in order from upstream side.Transfer cylinder 8, collect sheet-fed and be delivered to storage paper roll 9 from the pressure roller 6 of upstream side, this storage paper roll 9 has grippers 11 and the fixing paper adsorbent equipment 12 of end thereafter of absorption that rank is lived the leading section of sheet-fed, and with the predetermined angular zone of outer peripheral face from the footpath inwardly the side support sheet-fed.And, counter-rotating cylinder 10 is from storing the pressure roller 7 that paper roll 9 is collected sheet-fed and is delivered to the downstream, but when printed on both sides, the counter-rotating grippers 13 of counter-rotating cylinder 10 lives and collects the rearward end of sheet-fed from paper adsorbent equipment 12 ranks of storage paper roll 9, follow rotation, the counter-rotating grippers 13 of counter-rotating cylinder 10 to do slightly 180 degree rotations, make counter-rotating in the sheet-fed table and be delivered to pressure roller 7 to the direction of rotation rear side.Like this, in can the sheet-fed press of printed on both sides, because the position of the rearward end of the sheet-fed in storage paper roll 9 is very important, so need to be used for fixing the paper adsorbent equipment 12 that the rearward end of sheet-fed is used on the paper roll 9 in storage, simultaneously, need make the structure that distance changes according to the length of sheet-fed of leaving of Zhou Fangxiang between this paper adsorbent equipment 12 and the grippers 11.
Therefore, for example Fig. 9 is such for storage paper roll 9, has the place ahead supporter 20 and the rear supporter 21 with paper adsorbent equipment 12 of grippers 11, to constitute on engagement ground, front and back mutually.Specifically, the place ahead supporter 20 and rear supporter 21 have intermeshing comb tooth- like part 22,24 respectively.This combs tooth-like part 22,24, it is the part that on the direction of principal axis of storage paper roll 9, is arranged side by side in the tooth portion 23,25 that Zhou Fangxiang extends every predetermined distance, the place ahead supporter 20 has grippers 11 at the front end face of comb tooth-like part 22, and rear supporter 21 has paper adsorbent equipment 12 at the rear end face of comb tooth-like part 24.Thereby, between grippers 11 and paper adsorbent equipment 12, form the paper supporting surface of support sheet-fed from the outer peripheral face of two comb tooth-like parts 22,24.In addition, at the storage paper roll 9 shown in Fig. 9, three paper supporting surfaces are arranged in its periphery.Be so-called three times of formula cylinders, therefore, on three paper supporting surfaces, have grippers 11 and paper adsorbent equipment 12 respectively.
Before and after a side in two supporters 20,21 be not fixed on revolvably on the central shaft 26 of storing paper roll 9, the opposing party be constituted as can rotate on the central shaft 26 and position in hope on can fix.Thereby for example in the slit 27 that is formed between the tooth portion 23 of adjacency, the tooth portion 25 of the comb tooth-like part 24 of the supporter 21 by the opposing party enters, with the length ground that the is fit to sheet-fed paper supporting surface that can stretch.
Promptly, make rear supporter 21 relatively rotate, make the lengths of action of two comb tooth- like parts 22,24 to shorten gradually rearward and, make the length of the Zhou Fangxiang of paper supporting surface be maximum with the front end of the comb tooth-like part 24 of the rearward end of the comb tooth-like part 22 of the place ahead supporter 20 and rear supporter 21 state before being about to deviate from for the place ahead supporter 20.On the contrary, when making rear supporter 21 relatively forwards side rotates, makes the length of action of two comb tooth- like parts 22,24 elongated for the place ahead supporter 20, the paper supporting surface shrinks with it.
And the mode of building bridge between when the base end part of the comb tooth-like part 22 of supporter 20 forwardly, with the tooth portion 23 in adjacency the and when structure of bridge formation portion (diagram is omitted) is set is not only by each tooth portion 23 but also support the leading section of sheet-fed by bridge formation portion.Thereby, being in the leading section of the comb tooth-like part 24 of rear supporter 21, under the state of the bridge formation portion of contact the place ahead supporter 20, the length of the Zhou Fangxiang of paper supporting surface be minimum, printing machine can not print the sheet-fed of lacking than it.
To this, as shown in figure 10, the structure that also has the base end part of the comb tooth-like part 22 of supporter 20 forwardly not establish bridge formation portion.In this structure, forwardly on the comb tooth-like part 22 of supporter 20, the slit 27 that each tooth portion is 23 is side opening forwards also.Therefore, when the paper supporting surface is shunk, the leading section of the comb tooth-like part 24 of rear supporter 21, as among Fig. 9 and Figure 10 by shown in the double dot dash line, live the position by the paper rank of grippers 11, that is, forwards more outstanding than the leading section of sheet-fed.Thereby, as mentioned above because with the structure comparison that is connected by base end part, the paper supporting surface is shunk, so the increase of the stroke of paper supporting surface, its result also can print shorter sheet-fed, can expand the scope of the paper size of press printing.
In addition, as shown in figure 10, the axis direction of grippers 11 edge storage paper rolls 9 separates certain intervals and is arranged side by side.That is, each grippers 11 is configured on the position of each tooth portion 23 of combing tooth-like part 22, holds in the mouth the firmly leading section of sheet-fed with pawl platform 28 (with reference to Fig. 9) coordination.
Like this, the leading section of the comb tooth-like part 24 of rear supporter 21, forwards outstanding and constitute when the paper supporting surface shrinks, the base end part of the comb tooth-like part 22 of supporter 20 forwardly, the outer peripheral face of each tooth portion 23 leave mutually and are discrete state.Therefore, make paper supporting surface when elongation on the contrary, the leading section of sheet-fed is the outer peripheral face, supported on the axis direction devices spaced apart ground of storage paper roll 9 of each the tooth portion 23 by the place ahead supporter 20 only.Its result, as shown in figure 11, the end, the left and right sides of the sheet-fed W that do not lived by grippers 11 rank enters slit 27 and paper folding takes place easily.
Like this, when paper folding takes place, be used as be printed on one side, when counter-rotating cylinder 10 transmits sheet-feds, the possibility that counter-rotating grippers 13 ranks are lived the leading section of sheet-fed uprises, and becomes the main cause broken phenomenon brought by transmitting bad.
Therefore the present invention is in view of above-mentioned problem points in the past, and bad to prevent to the transmission generation of counter-rotating cylinder, the scope that enlarges the size of the sheet-fed that can use simultaneously is problem.
Summary of the invention
The present invention is the invention that can solve above-mentioned problem, the storage paper roll of perfecting press of the present invention, be when carrying out printed on both sides,, it is characterized in that: have: be provided with the place ahead supporter of the grippers of holding in the mouth the sheet-fed leading section and be provided with the fixedly rear supporter of the paper fixture of sheet-fed rearward end to making the counter-rotating cylinder that reverses in the sheet-fed table transmit the storage paper roll of the perfecting press of sheet-fed; Comb tooth-like part by the place ahead supporter of rearward extending from grippers and from the comb tooth-like part of the rear supporter that the paper fixture is forwards extended mutually before and after engagement, make paper supporting surface between grippers and paper fixture, that form by two outer peripheral faces of combing tooth-like parts to stretch, so that consistent with the length of sheet-fed; When the paper supporting surface was shunk, the leading section of the comb tooth-like part of rear supporter forwards protruded in the paper rank of grippers and lives the position; Be between the tooth portion of adjacency on the comb tooth-like part of the place ahead supporter, be provided with the paper support component of the leading section that supports sheet-fed, this paper support component when the paper supporting surface shrinks, is kept out of the way from the paper Support Position that should avoid conflicting with the leading section of the comb tooth-like part of rear supporter.
In this constitutes, when the paper supporting surface is shunk, because the paper support component keeps out of the way the paper Support Position, so can avoid and the conflicting of the leading section of the comb tooth-like part of rear supporter, it is outstanding to the front portion to make the comb tooth-like part of rear supporter live the position than the paper rank of grippers.
Particularly, the paper support component, be set to can to the storage paper roll radially go out to move back, and when the paper supporting surface shrinks radius vector inwardly just to keep out of the way be desirable.Inwardly keep out of the way the side by radius vector, can prevent interference easily with other component parts.
In addition, the paper support component is desirable by inwardly square keeping out of the way of cam mechanism radius vector, can be made as easy structure to the structure that is used to keep out of the way.
And then, when supporter is relatively near the place ahead supporter in the wings, the cam mechanism action, inwardly square keeping out of the way of paper support component radius vector is desirable.Like this, by the action interlock of cam mechanism and rear supporter, just there is no need to make cam mechanism action independently in addition.
Form cam surface on the side in two supporters of front and back and cam follower is set as cam mechanism on the opposing party, when supporter was relatively near the place ahead supporter in the wings, cam follower contacted with cam surface, and the cam mechanism action is desirable.Like this, by cam mechanism directly being set, not only do not need to make the other mechanism of cam mechanism action, and the action of cam mechanism is also reliable at two supporters itself.
In addition, the paper support component is desirable in the front openings portion that is set to slightly block the slit between the tooth portion on the paper Support Position.Slightly block front openings portion by the paper support component, suppress to flow into air, can suppress the chaotic and distortion of the sheet-fed that produces to flow into air, sheet-fed can stably be delivered on the counter-rotating cylinder to slit.
In addition, the paper support component is formed lamellar, and in the front openings portion that is set to slightly block the slit between the tooth portion on the paper Support Position, and, the paper support component be set to can to the storage paper roll radially go out to move back, and the interior side who keeps out of the way radially when the paper supporting surface shrinks is desirable.According to such structure, can suppress effectively to flow into air to slit, and, owing to be lamellar and to radially going out to move back, so can prevent easily and other the interference of component parts.

The specific embodiment
Below, to an embodiment of the storage paper roll of perfecting press of the present invention, describe, the component part that has illustrated is omitted the explanation of its repetition when giving identical symbol referring to figs. 1 to Fig. 6.
In addition, Fig. 1 is the stereogram corresponding to Figure 10, Fig. 2 and Fig. 4 see the figure of the place ahead supporter 20 with the state that omitted grippers 11 from front side, and Fig. 3 is the cutaway view of the P-P line of Fig. 2, and Fig. 5 is the cutaway view of Fig. 3 that is in the state of retreating position corresponding to the paper support component.In addition, the direction of rotation that arrow R represents to store paper roll 9 in Fig. 3.
As mentioned above, storage paper roll 9 has the place ahead supporter 20 and rear supporter 21, sees that to the axis direction of storage paper roll 9 they all are provided with three with the interval of 120 ° of summaries altogether in sector region.That is, storage paper roll 9 is so-called three times of formula cylinders.
On the Zhou Fangxiang of sector region front end face, be provided with the grippers 11 of living the leading section of sheet-fed with pawl platform 28 coordinations rank, on the Zhou Fangxiang rear end face, be provided with the fixedly paper adsorbent equipment 12 of the rearward end of sheet-fed (paper fixture) of absorption.Pawl platform 28, is fixed by screw respectively on the front end face of each the tooth portion 23 in comb tooth-like part 22, but also can be formed to shown in Figure 4 as Fig. 2.In addition, cut apart at the axis direction pawl platform 28 of storage paper roll 9 like this, this is because at the slit 27 of 23 formation of tooth portion of adjacency also side opening forwards, when its front openings portion paper supporting surface shrinks, the leading section of each tooth portion 25 of the comb tooth-like part 24 of rear supporter 21, as shown in Figure 5, also forwards more outstanding than pawl platform 28.
Like this, the slit 27 that between the tooth portion 23 of adjacency, forms, side opening forwards, but the paper support chip 30 of the leading section that supports sheet-fed is set in the slit 27 between the tooth portion 23 of adjacency.This paper support component 30, on Fig. 2 and paper Support Position shown in Figure 3, the outer peripheral face of its upper surface (be last with the footpath direction outside) and tooth portion 23 is slightly with simultaneously, supports the leading section of sheet-fed with tooth portion 23.Paper support chip 30 as shown in Figure 2, the front openings portion of be located at slit 27 places respectively, slightly blocking slit 27 erects with the dividing plate shape and is being provided with.Thereby the leading section of sheet-fed supports at the direction of principal axis along storage paper roll 9 slightly continuously by tooth portion 23 and paper support chip 30.In addition, also be provided with paper support chip 30 in the outside of the tooth portion 23 at two ends, the left and right sides.
In addition, each paper support chip 30, the axis direction in its bottom in storage paper roll 9 is connected integratedly, is constituted a laminal gripper shoe.That is, paper gripper shoe 31, end thereon, a plurality of paper support chips 30 are provided with so that predetermined distance is outstanding along the axis direction of storage paper rolls 9, are formed slightly zigzag as a whole as shown in Figure 2.This paper gripper shoe 31 as shown in Figure 3, is configured in the rear side near pawl platform 28.Thereby, when on counter-rotating cylinder 10, transmitting sheet-fed, can not interfere with counter-rotating grippers 13.
And then when the paper supporting surface shrank, for fear of the leading section of the tooth portion 25 of rear supporter 21 and the conflict of paper support chip 30, paper gripper shoe 31 was the structures that go out to move back to radially.Specifically, from keep out of the way interior side radially in Fig. 2 and paper Support Position shown in Figure 3, be Fig. 4 and retreating position shown in Figure 5.Below be elaborated.
The front end face of the comb tooth-like part 24 of supporter 20 forwardly, for and its front end face between form predetermined gap, pressing plate 32 is fixed as screw by screw 33, betwixt configuration paper gripper shoe 31 in the crack.Paper gripper shoe 31 has the slotted hole 34 that extends to radially, connects this slotted hole 34 by screw 33, and paper gripper shoe 31 can be to moving radially in the gap.
In addition, form the slotted hole 35 that extends to radially, in paper gripper shoe 31 pin 36 is installed highlightedly to the front portion, on this pin 36, connect outboard end to the axle 37 that radially extends from this slotted hole 35 at pressing plate 32.This 37 run through supporting base 38 and within it side end have the columnar component 39 that the axis direction to storage paper roll 9 extends, this columnar component 39 cooperates with the recess of the summary U font of an end that is formed on rotating connecting part 40.Rotating connecting part 40 is installed in the other end along being that fulcrum rotates with fulcrum 41 on the fulcrum 41 of axis direction of storage paper roll 9 and with the rotation of this fulcrum 41.In addition, as shown in Figure 2, separate predetermined distance at the axis direction of storing paper roll 9, axle 37 etc. is set at two places, two rotating connecting parts 40 are separately fixed at the both ends of fulcrum 41.In addition, on fulcrum 41, the cam follower mounting base 43 with cam follower 42 is installed in leading section.This cam follower mounting base 43 is between two rotating connecting parts 40.
In addition, the cam surface 44 that contacts with cam follower 42 is formed on the rear supporter 21.In the wings on the supporter 21 as shown in Figure 3, at the forwards outstanding cam of inside square one-tenth in footpath of its comb tooth-like part 24 with protuberance 45.Be formed with cam surface 44 at this cam with the inner face of protuberance 45, this cam surface 44 is made of than the 2nd cam surface 44b that it tilts to relax the 1st big cam surface 44a of relative tilt and the 1st cam surface 44a that continues.
In addition, between pin 36 and supporting base 38, be contained on the axle 37 as the helical spring of force application apparatus (diagram is omitted) is outer, by its elastic force make paper gripper shoe 31 always by roof pressure to radially foreign side.In addition, symbol 46 is the support components that support fulcrum 41 among the figure.
Then, the action with regard to paper gripper shoe 31 is described.At first, when the paper supporting surface shrinks, make rear supporter 21 side shifting forwards, when the leading section of the comb tooth-like part 24 of rear supporter 21 is come the front of contact paper support chip 30, cam contacts with cam follower 42 with the cam surface 44 of protuberance 45, is pushed cam follower 42 and fulcrum 41 is rotated with predetermined angular by cam surface 44.This rotatablely moves by rotating connecting part 40 and columnar component 39, is converted to rectilinear motion radially, is delivered on the paper gripper shoe 31 by axle 37.Thereby, with approaching comb tooth-like part 24 linkedly, paper gripper shoe 3 inchmeal radius vector inwardly move side's (arrow S direction of Fig. 2), directly move to retreating position shown in Figure 5.
On the contrary, when the rear supporter 21 that the paper supporting surface should be extended when move at the rear portion, along with this moves, gripper shoe 31 radius vectors move and turn back to paper Support Position shown in Figure 3 to foreign side's (arrow L direction of Fig. 4).
As previously discussed owing between the pawl platform 28 of supporter 20 paper support chip 30 is set forwardly, so make should paper supporting surface elongation corresponding to long paper size in, as shown in Figure 6, support the both side ends of sheet-fed W by paper support chip 30.
Thereby, can transmit sheet-fed to counter-rotating cylinder 10 reliably, can prevent by transmitting the phenomenon that the bad paper that brings damages.Particularly owing in each slit 27, be provided with paper support chip 30, thus change that also can corresponding paper web, and, owing to also be provided with paper support chip 30, so sheet-fed that also can corresponding width of cloth broad in the outside of the tooth portion 23 at two ends.In addition, owing on a piece of paper gripper shoe 31, form each paper support chip 30, thereby cost is low and assembling is also convenient, owing to can move the travel mechanism that therefore can simplify paper support chip 30 with being integral.
And then, since for the front openings portion of slightly blocking slit 27 with dividing plate shape ground configuration paper support chip 30, therefore with relatively can suppress inflow air in the place ahead side direction slit 27 significantly in the past.When air flows into to slit 27, can cause the chaotic and distortion of sheet-fed, make easily to transmit to become unreliable with this.To this, as present embodiment,, can suppress the inflow of air, and can prevent to transmit bad because sheet-fed is stable to slit 27 by slightly blocking front openings portion by paper support chip 30.
In addition, owing to when the paper supporting surface shrinks, make paper support chip 30 keep out of the way retreating position, can prevent and the conflicting of the comb tooth-like part 24 of rear supporter 21, by comb tooth-like part 24 is become than lived the also forwards outstanding state in position by the paper rank of grippers 11, can make grippers 11 and paper adsorbent equipment 12 more approaching.Thereby also can corresponding sheet-fed of lacking size.
At this moment owing to be to make inwardly side's formation of keeping out of the way of paper gripper shoe 31 radius vectors, therefore have can avoid easily with other component parts, particularly with the advantage of the interference of counter-rotating grippers 13.Particularly,, so as mentioned above, the inflow of air can be suppressed effectively, interference can be prevented simultaneously easily with other component parts in the paper Support Position to slit 27 because paper gripper shoe 31 is lamellar and radius vector is inwardly square mobile point-blank.But, as shown in Figure 7, also can adopt paper gripper shoe 31 to rotate and the structure of keeping out of the way.
In addition, owing in the present embodiment paper gripper shoe 31 is kept out of the way by the cam mechanism that is made of cam surface 44 and cam follower 42, formation is simple and control is also easy.And then, automatically move when connecting nearby square supporter 20, with action interlock, the cam mechanism of this rear supporter 21 paper gripper shoe 31 is kept out of the way, so the operator does not make necessity of cam mechanism action in addition owing to rear supporter 21.At this moment, particularly, owing on supporter 20 and the rear supporter 21 cam surface 44 and cam follower 42 are set directly forwardly, therefore by both approaching, leave, paper support chip 30 can be moved easily and reliably in paper Support Position and retreating position, in addition, do not need to make the other mechanism of cam mechanism action usefulness yet.And then, because by the motion of cam follower 42 being delivered on the paper gripper shoe 31, so can be by simple mechanism from the paper gripper shoe 31 that moves away from reliably by rotating connecting part 40 and axle 37 bindiny mechanisms that constitute.
In addition, in the present embodiment, used a piece of paper gripper shoe 31, but also can be by many structure.Other as the paper support component, can certainly use lamellar paper support component in addition.In addition, the storage paper roll of three times of cylinders is illustrated, but also can be suitable for storage paper roll or four times of storage paper rolls more than the cylinder of single entry cylinder and double cylinder.
(invention effect)
As shown above, because by the paper support component of the leading section that supports sheet-fed is set, Can prevent inwardly side's bending of side end radius vector of sheet-fed between the tooth section, so can roll in counter-rotating Transmit reliably sheet-fed on the tube, can prevent by transmitting the bad broken phenomenon of bringing. And, Because the paper support component is kept out of the way from the paper Support Position when the paper supporting surface shrinks, and can avoid and the rear The leading section of the comb teeth-shaped section of supporter and paper support component conflict, thereby, make the rear supporter The leading section of comb teeth-shaped section than lived by the paper rank of grippers the position also forwards highlightedly, can advance one Step is shunk the paper supporting surface, can reach the scope of the paper size that enlarges spendable sheet-fed.
