Guidance panel 58 has omitted diagram, has plate-making beginning key, printing beginning key, other various setting keys etc.
Hole plate print device 1, such as has been said, constitute and can carry out for of the printing of long size with paper P.Therefore, in ROM, except storing the common operation program with the operation program of paper P, when also storing the long size of printing with paper P.
Based on above-mentioned formation, the below action of explanation hole plate print device 1.In addition, make plate cylinder 9 be common plate cylinder 9.Hole plate print device 1, when long size is used the printing of paper P, control its action as follows by controlling organization 57, so that carry out once ratio with whenever rotating a circle of plate cylinder, carry out paper supply action, and carry out to grow the push action that size is pushed to plate cylinder 9 with paper P by pressure roller 10 from sheet feed section 4.Also can repeatedly carry out once these actions of proportion control with general cylinder 9 every rotations.
Contacting on the glass 51 or the original copy that mounting will be printed on the ADF unit 56, then, if press plate-making beginning key by operating personnel, then image reading unit 7 actions and carry out reading of original image, and 5 actions of composing portion and the mother matrix 24 of version before peeling off from plate cylinder 9.3 actions of then plate-making portion are finished in action if set type, and carry out the plate-making action to mother matrix 24.
Transport roller to 22,23 and the mother matrix 24 after the carrying plate-making by air roll 19 and each mother matrix, by clamp 15 and the top that keeps mother matrix 24.Then, plate cylinder 9 rotates and carries out the package action of mother matrix 24, and controlling organization 57 has transported 1 edition corresponding mother matrix 24 if pick out plate-making by the number of steps of stepper motor 25, and then mother matrix shut-off mechanism 21 moves and cut-out mother matrix 24.Pull out the mother matrix 24 that has cut off by the rotation of plate cylinder 9 and from the inside of plate-making portion 3, finish the package action and hole plate print device 1 becomes the printing holding state.
After hole plate print device 1 is for the printing holding state, set the formation position, print speed printing speed, printing number of printing image etc. by the various setting keys on the guidance panel 58, then, press printing beginning key, then rotate and drive plate cylinder 9 with the circular velocity corresponding with the print speed printing speed of having set, and if controlling organization 57 is based on judging that from the signal of encoder 16 plate cylinder 9 arrives set position, then drive paper supply motor 31 and rotation driving paper feed roller 27 and separate roller 28a, supply with from paper supply tray 26 and use paper P.
What be supplied to uses paper P, is separated into one in separating feed mechanism 28, sends to resistance roller 29 afterwards.This moment on solenoid 36 no power, resistance roller 29 occupies crimping position., then, behind the clamping section butt of resistance roller 29, and then be supplied to by detecting its top with paper top detecting sensor 62 with paper P, separate roller to 28 and resistance roller 29 between form deflection.On with paper P, form both quantitative deflection if controlling organization 57 is judged by the number of steps of paper supply motor 31, then stopped the action of paper supply motor 31.
Afterwards, if controlling organization 57 can be to the position with both allocations printing of paper P based on identify the image that plate cylinder 9 rotated to the mother matrix 24 that is wrapped on the plate cylinder 9 from the signal of encoder 16, then under this supplies with beginning opportunity, stepper motor begins to move and drives driven roller 29a with circular velocity identical with the circular velocity of plate cylinder 9 or slow slightly circular velocity rotation, supplies with from resistance roller 29 to Printing Department 2 and uses paper P.With paper P is common during with paper P, makes to supply with beginning opportunity for can form the opportunity of the blank of 5mm on the end of downstream side among the direction X of paper P.In addition, blank is meant and the regional corresponding part in the outside of can making a plate.
Under the opportunity consistent with the image apex of mother matrix 24 with near the both allocations the top of paper P, swing mechanism moves, and pressure roller 10 occupies crimping position, thereby is crimped on the mother matrix 24 on the plate cylinder 9, to printing with paper P with paper P.Based on the revolution speed of the driven roller 29a of stepper motor 37, only can be that the print speed printing speed of hole plate print device 1 changes accordingly with the circular velocity of plate cylinder 9.In addition, supplying with beginning also can adjust with the print speed printing speed of hole plate print device 1 opportunity accordingly.
Transfer printing image use paper P, by separation claw and peel off, send downwards by the mother matrix 24 that its top begins from the plate cylinder 9.That sends downwards uses paper P, be attracted on the endless belt 47 by the attraction that attracts fan 48, by the rotation of endless belt 47 and and then be transported downstream and send to discharge tray 44.At this moment, driven roller 45 is to be driven in rotation based on the travelling speed with paper P of endless belt 47 circular velocity faster slightly than the circular velocity of plate cylinder 9, and what be printed is transported with the state that is applied in little tension between plate cylinder 9 and endless belt 47 with paper P.
If the whole transfer printings of the image of mother matrix 24 quilt on usefulness paper P, are then removed the action of swing mechanism and are made pressure roller 10 occupy the separation point position.Occupy at pressure roller 10 under the state of separation point position, the revolving force of plate cylinder 9 is to applying with paper P, mainly is only to be transported by side downstream by the transport force of transporting parts 43 with paper with paper P.
At this moment,, then be subjected to the influence of the frictional resistance of resistance roller 29, can not carry out good transporting with transporting of paper P if make resistance roller 29 occupy crimping position.Thus, controlling organization 57 based on identify the position that pressure roller 10 occupies the plate cylinder 9 before the separation point position from the signal of encoder 16, is switched on as separation opportunity this to solenoid 36, make resistance roller 29 be positioned at the separation point position.Thereby can roughly eliminate based on resistance roller 29 and to the frictional resistance that applies with paper P, so can not exist on paper P and influence the resistance that transports that it transports degree, only transported well by side downstream with paper P, can prevent to transport the generation of obstruction with paper by the transport force of transporting parts 43 with paper.
In addition, as shown in Figure 5, resistance roller 29 have after occupying the separation point position, still be driven in rotation during, so after separation opportunity, in this period, bear transport force based on driven roller 29a with paper P.In addition, after separation opportunity, before breaking away from driven roller 29a, bear frictional resistance, still with paper P based on driven roller 29a with paper P rear end, driven roller 29a is driven in rotation during described, so lowered the frictional resistance that is born with paper P in this period.
The separation opportunity that resistance roller 29 is moved to the separation point position, also can not be pressure roller 10 occupy the separation point position slightly before, but after Printing Department 2 supplies with, seized on both sides by the arms after a while opportunity by plate cylinder 9 and pressure roller 10 by resistance roller 29 with the top of paper P with paper P.
In addition, make resistance roller 29 to butt opportunity that crimping position moves, when the size of supplying with to Printing Department 2 with paper P is the B4 size, be set to the opportunity of passing through the opportunity that breaks away from resistance roller 29 with the upstream side end among the rear end direction X of paper P between driven roller 29a and the driven voller 29b after a while, can shorten many and print the needed times.Like this, butt opportunity and print speed printing speed are irrelevant, become the opportunity that phase place with respect to the plate cylinder 9 that is used to print becomes certain relation.
Therefore, no matter the kind of plate cylinder 9, even if the time to the printing of arbitrary dimension with paper P, the top in the zone of can making a plate in mother matrix 24 is that the position of the end of downstream side of direction R all is certain with respect to the phase place of plate cylinder 9, in addition, supplying with beginning opportunity is certain with respect to the phase place of plate cylinder 9 also, then be formed on head portion with paper P and be length on the end of downstream side part of direction X, the blank in direction X, with irrelevant but fix with the size of paper P.
On the other hand, when forming blank on the end sections of wanting at direction X of using paper P, in press use long size paper P sometimes.In the time will growing size and be used to print with paper P, if supply with beginning opportunity with to common identical when printing with paper P, then on the upstream-side-end part in direction X with paper P, in direction X, form than common blank with paper P length, but, on the end of downstream side part in direction X with paper P, in direction X, form with to the common blank of equal length when printing with paper P.
But, have following expectation, promptly wish on the end of downstream side part in direction X with paper P, form than to common when printing with paper P on direction X the blank of length.In this case, push opportunity, be used in then that to carry out described mechanism of pushing complicated, cause the maximization of hole plate print device 1, complicated, high price to be formatted with paper P if will change to plate cylinder 9.
In addition, if making separation opportunity is above-mentioned opportunity, then do not bear the resistance of resistance roller 29 with paper P, only by mainly transporting the transport force of parts 43 and being transported well by side downstream with paper, can prevent to transport the generation of obstruction with paper, but, thereafter butt opportunity is before the rear end of sending to plate cylinder 9 with paper P breaks away from, then on both sides, apply burden, have the printing of generation bad with paper P and resistance roller 29, the hole plate print device 1 of Printing Department's 2 grades bad, based on transport the bad of parts 43 with paper with transporting of paper P, transport the generation of obstruction with paper, and then the possibility of generation noise.
Such phenomenon, particularly, as hole plate print device 1 make for its densification the resistance roller 29 and the distance of Printing Department 2 become with the corresponding length with paper P of B4 size and the situation of lacking than long size usefulness paper P under, and under the situation of printing with paper P, be easy to generate to long size, in addition, by in growing the situation that size prints with paper P, being easy to generate above-mentioned phenomenon for the hole plate print device 1 that shortens rear end that printing time makes butt become B4 size opportunity opportunity after breaking away from resistance roller 29 with paper P.
Therefore, in hole plate print device 1, under the situation of printing using common plate cylinder 9, if the supply during order the size that is used to the print size that to be B4 following with paper P begin opportunity for the size below the B4 with paper P be benchmark set shown in Fig. 5 (a) the 1st opportunity T1, then make when the common plate cylinder 9 of use prints, be used to print with paper P be the length size with the supply beginning under the situation of paper P be opportunity than shown in Zao, this figure (b) of the 1st T1 on opportunity the 2nd opportunity T2.
Thus, even if do not change the structure of machinery, shown in Fig. 6 (a), with compare to the situation of supplying with the B4 size corresponding to the zone of can making a plate of B4 size with paper P, shown in Fig. 6 (b), on the end of downstream side part under the direction X, in direction X, be formed with longer blank with paper P.
In addition, the long size paper P that in orifice plate printing equipment 1, is used for printing, when using full-size to be printing of A3 size with paper P, be the opportunity with the rear end disengaging resistance roller 29 of paper P the mode on butt opportunity be provided with the 2nd opportunity T2.
Thus, even if do not change the structure of machinery, with the rear end of paper P butt in opportunity also not by 29 clampings of resistance roller, so do not apply burden to both sides with paper P and resistance roller 29, can prevent that long size printing is bad, the hole plate print device 1 of Printing Department 2 etc. bad, based on transport with paper parts 43 bad with transporting of paper P, transport the generation of obstruction, the generation of noise with paper.
Such control, by controlling organization 57, be long size during only, and carry out when plate cylinder 9 is the signal of small size with plate cylinder 9 not importing from plate cylinder species detection mechanism 64 with paper P in the size of measuring by paper size testing agency 63 with paper P.Thus, when printing, big blank can on direction X downstream, not occur, and the printing image can not overflow in the direction X upstream-side-end of paper P to common with paper P.
If adjust printing, then as shown in Figure 7 based on described control.
Promptly, if press printing beginning key as described above, then paper supply motor 31 is driven and grows the paper supply (S1) of size with paper P, long size arrives the resistance roller 29 (S2) that is positioned at as the crimping position of original position with the top of paper P, then after supply beginning opportunity promptly under the 2nd opportunity T2, resistance roller 29 is driven in rotation and grows size and supplied with (S3) to Printing Department 2 with paper P, if long size arrives Printing Department 2 (S4) with the top of paper P, then after promptly corresponding opportunity on opportunity with the tip side position of range L 1 in, pressure roller 10 occupies crimping position (S5).
Then, long size with the top of paper P arrive arrange paper portion 6 transport parts 43 (S6) with paper, the opportunity corresponding with the rear end side position of range L 1 slightly before separate under opportunity, resistance roller 29 occupies separation point position (S7), afterwards, under the opportunity corresponding with the rear end side position of range L 1, pressure roller 10 occupies separation point position (S8).Then, long size with opportunity (S9) of the rear end of the paper P resistance roller 29 by occupying the separation point position slightly before separation opportunity under, resistance roller 29 occupies crimping position (S10).
Controlling organization 57 judges whether the number of completed printing reaches the printing number (S11) of setting, be judged as do not reach before, repeatable operation to step S10, finishes printing if be judged as to reach then from step S1.
On the other hand, when using small size to print with plate cylinder 9, as along Fig. 3 explanation, occupy the opportunity of separation point position for pressure roller 10, opportunity when using small size with plate cylinder 9 is Zao when using common plate cylinder 9, so, be long size paper P as if what be used to print with paper P, it transports bad possibility then to have generation.This be because, if pressure roller 10, resistance roller 29 occupy the separation point position, then only obtain, as if with paper P being long size paper P by transporting parts 43 with paper with the transport force of paper P is main, then increase, increase based on the resistance of friction with the length of the part of the common rear end side of comparing direction X with paper P.
Therefore, hole plate print device 1 is using small size to connect 9 when printing with forme, and is long size during with paper P what be used to print with paper P, shown in Fig. 5 (c), make the supply beginning become opportunity than the 2nd opportunity T2 more Zao, the 3rd opportunity T3.
Thus, shown in Fig. 6 (c), on the end of downstream side part of direction X with paper P, in direction X, form longer blank, correspondingly, arrive the length growth of transporting parts 43 with paper, can obtain based on the transport force of transporting parts 43 with paper, and the contraction in length of the part of the rear end side of direction X can reduce the resistance based on friction, and it is bad with transporting of paper P to prevent and even suppress long size.
In addition, in upstream side and the downstream of direction X, blank balance also improves.Among this figure (c), the profile in the zone of can making a plate when chain-dotted line is represented to use common plate cylinder 9.Small size is with the zone of can making a plate of plate cylinder 9, the zone of can making a plate when ratio uses common plate cylinder 9 in the upstream side of direction X is short, when using long size to print with paper P, make supply with beginning be opportunity the 3rd opportunity T3, so blank balance improves on the upstream side of direction X and downstream.
Such control, by controlling organization 57, be long size during only, and be that small size is carried out in the signal of plate cylinder 9 from plate cylinder species detection mechanism 64 input plate cylinders 9 with paper P in the size of measuring by paper size testing agency 63 with paper P.Thus, when printing, big blank can on direction X downstream, not occur, and the printing image can not overflow in the direction X upstream-side-end of paper P to common with paper P.
For above such control, also can by guidance panel 58 input expression be used to print with paper P be common with paper P and long size with which the size of using paper P among the paper P, guidance panel 58 plays a role as paper size testing agency at this moment.In addition, can whether be small size plate cylinder 9 also by guidance panel 58 input plate cylinders 9, guidance panel 58 plays a role as plate cylinder species detection mechanism at this moment.
When carrying out such control, carry out the printing identical with explanation shown in Figure 7.But, in step 3, resistance roller 29 be driven in rotation and long size with paper P be the opportunity to Printing Department's 2 supplies the 3rd opportunity T3.In addition, in step 8, be the opportunity corresponding with the rear end side position of range L 2 opportunity that pressure roller occupies the separation point position.
