<The method of operating of printing equipment>

Below, the elemental motion method to printing equipment 1 illustrates.Fig. 4 to Fig. 7 is the action side for showing printing equipment The schematic diagram of method.In the following description, to being delivered to post-processing unit 300 from printing element 100 by temporary location 200 Paper M conveying form illustrates.In addition, by supply, be delivered to printing element 100 record printhead 111 paper M from First page starts to be set to the first paper Ma, the second paper Mb, the 3rd paper Mc successively, and the paper M of page four is set into the 4th paper Md, the paper M of page four all illustrate as dry paper M is eliminated.

First, when performing printing treatment (printing treatment of image), control unit 10 drives each motor class.Thus, The pickup roller 142a of each motor, conveying roller are connected to 131, driven roller 133, the first conveying roller to the 254, second conveying roller Roller is turned to 257, first to the 256, the 3rd conveying roller turn roller to 265, second and 268 and conveying roller are driven to 327 etc. It is dynamic.

Also, the discharge ink from record printhead 111 to paper M of record portion 110, so as to print image.It should be noted that In this case, printing treatment can be printed on one side or printed on both sides.

Also, as shown in figure 4, the first paper Ma conveyed with speed before turning in the 3rd discharge path 153 is with substantially Same speed is delivered in lead-in path 243.Also, when importing test section 258 detects the first paper Ma front end, control Portion 10 drives solenoid, guiding wing 259 is located at first position P1.I.e., guiding wing 259 guides the first paper Ma to first point Branch path 244.Also, the first paper Ma for being transported to the first tie point B is contacted by front end with the first limitation wing 261, with The mode resisted in the force of force application part moves the first limitation wing 261.I.e., first the wing 261 is limited to open first point The mode of the downstream of branch path 244 moves.Therefore, the first paper Ma turns roller to 265 by the first of forward drive First, which is admitted to, with speed before turning turns path 248.Also, once the first paper Ma is by the first limitation wing 261, then first The limitation wing 261 is moved to from the position for opening the first downstream for turning path 244 and blocks the first downstream for turning path 244 Position.

As shown in figure 5, when first turns test section 264 and detect the first paper Ma rear end, control unit 10 will rotate forward The first of driving turns roller and reverse drive is switched to 265.So, first portion 241 is turned to turn rear speed by the first paper Ma turns path 248 from first and sent out to the first tie point B sides.In addition, now, the first limitation wing 261 draws the first paper Ma It is oriented to first and converges path 246.I.e., first turn portion 241 by by from the first paper Ma that the first individual path 244 is sent into First converges path 246 sends out, so as to turn and (go back to) the first paper Ma direction.

In addition, when importing test section 258 detects the second paper Mb front end, control unit 10 drives solenoid to change The position of guiding wing 259.I.e., control unit 10 makes the guiding wing 259 positioned at first position P1 be moved to second place P2.So, Guiding wing 259 guides the second paper Mb to the second individual path 245.

As shown in fig. 6, convey turn portion 241 through first and turn first to turn rear speed in rear path 218b is turned Paper Ma.Also, control unit 10 makes first to turn roller and rotated forward to 265 and rotated when the first paper Ma is by the first tie point B. In addition, control unit 10 when second turns test section 267 and detect the second paper Mb rear end, makes second, to turn roller anti-to 268 To rotation.I.e., second turn portion 242 and first turn portion 241 in the same manner as turn the second paper Mb, with turn rear speed by its to Second, which converges path 247, sends out.

Moreover, when importing test section 258 detects the 3rd paper Mc front end, control unit driving solenoid draws to change The position of guide vane 259.Specifically, control unit 10 makes the guiding wing 259 positioned at second place P2 be moved to first position P1. I.e., guiding wing 259 will alternately convey next paper M and guide to the first individual path 244 and the second individual path 245.

As shown in fig. 7, through second turn portion 242 turn and be sent to second converge the second paper Mb in path 247 via Point D and conveyed in path 250 is exported.In addition, now, middle delivery section 252 is with than slow-footed tune before turning Turn rear speed to convey the first paper Ma and the second paper Mb.Therefore, with being entered with turning preceding speed in path 218a before turning Compared during row conveying, the interval of the first paper Ma and the second paper Mb in the conveying direction diminishes.

Also, when first turns test section 264 and detect the 3rd paper Mc rear end, control unit 10 makes first to turn roller Reversely rotated to 265, the 3rd paper Mc is sent into first converges path 246.

In addition, when importing test section 258 detects the 4th paper Md front end, control unit 10 drives solenoid, will draw The position of guide vane 259 is changed to second place P2.

Then, temporary location 200 is sent out to post-processing unit 300 successively since the first paper Ma first imported.I.e., paper M its paper M faces in temporary location 200 are opened to be turned and be transported to post-processing unit 300.In addition, downstream delivery section 335 so that than turning rear fireballing processing speed conveying paper M, therefore, the interval between paper M expands.Also, paper M quilts Paper piler 328 is delivered to successively, and when the paper M of regulation number of pages has been loaded in paper piler 328, luggage is entered by processing unit 325 The processing such as order, and 329 driving is discharged to discharge tray 331 by exit roller.

Below, the technical problem involved by the post-processing unit 300 of present embodiment is illustrated.As described above, In the case that printing element 100 possesses the ink-jet printer for the record printhead 111 that ink spues as drop, exist and pass through With the absorption of inking (moisture), drying of ink etc. curling (paper bending occurs for the paper M that printing element 100 has printed image State, the state rolled up of paper) situation.Therefore, in paper piler 328, if the paper M first loaded amount of crimp Greatly, then the paper M come is conveyed after producing bad worry is stacked due to the paper M first loaded curling.It is if in addition, logical Cross printing element 100 printed image paper M ink (moisture) drying it is insufficient, then can be due to residual on paper M surface Moisture has been stayed, has been raised so as to the frictional resistance on paper M surfaces.Therefore, will printed by printing element 100 (ink-jet printer) Brushed image paper M be placed in paper piler 328 successively in the case of, if the frictional resistance on the paper M first loaded surface Rise, then the paper M that the paper M come is first loaded is conveyed after having and is involved, so as to produce the irregular alignment in paper M end Bad worry.

And then the generation mechanism of the curling to paper M is described in detail.The paper M of present embodiment is configured to fibre Dimension element is principal component, and the cellulose is formed by hydrogen bonding each other.Therefore, by printing element 100 paper M's When simultaneously upper coating is black, due to the absorption of ink, the hydrogen bonding between cellulose disconnects.So, between cellulose It is easier to extend every expansion, compared with the another side opposite while with this of paper M for the paper M for being coated with ink.Therefore, exist During mounting that a paper M surface side is (downward) towards gravity direction, it is a convex (secondary volume that paper M crimps towards gravity direction It is bent).

In addition, after once curling is generated, if the black propulsion of drying that paper M is absorbed, cellulose that This is freely combined because of hydrogen bonding, and the interval between cellulose diminishes.So, the paper M of ink one side is coated with than another More shrink in face.Therefore, when making a paper M surface side be loaded towards gravity direction, with situation about once crimping on the contrary, It is concavity (the opposite direction side towards gravity direction is convex) (secondary coil) that paper M crimps towards gravity direction.

In addition, the generation of above-mentioned paper M curling is not limited in being printed on one side, can similarly be produced in printed on both sides It is raw.I.e., when the printing duty (printing duty) in paper M one side is different with the printing duty on another side, easily Curling is produced on paper M.Particularly, the difference of the printing duty on the printing duty and another side in paper M one side is rule More than fixed when (for example, about more than 30%), paper M curling generation is then more obvious.It should be noted that " duty " refers to lead to Cross duty (%)=physical record points/(in formula, " physical record points " are every lists for (vertical resolution ratio × horizontal resolution ratio) × 100 The physical record points of plane product, " vertical resolution ratio " and " horizontal resolution ratio " is the resolution ratio of per unit area respectively) calculate Value.In addition, paper M printing duty difference refers to the difference of the amount of moisture of paper M positive and negative (simultaneously and another side).

Then, possesses drying unit 270 in temporary location 200, the drying unit 270 is for being placed in post-processing unit The paper M of 300 paper piler 328, suppress paper M dries deficiency, deformation (curling).By drying unit 270, can reduce It is placed in aliging caused by the paper M of paper piler 328 high frictional resistance and stacks bad hair caused by bad, curling It is raw.

Temporary location 200a involved by second embodiment does not possess the directing plate 271 that paper M is guided when drying, and It is to possess tension force imparting mechanism, this point is different from the temporary location 200 of first embodiment.

<Tension force imparting mechanism>

Temporary location 200a is provided with the tension force imparting that tension force is assigned to paper M to suppress the deformation such as paper M curling Mechanism.As shown in figure 15, tension force imparting mechanism is arranged at second and turns path 249.Tension force imparting mechanism by the first roller to 268a, Second roller is to 268b and the first roller is turned path 249 along second to 268b relative position relative to the second roller to 268a The gearshift composition (not shown) that (transport path 218) changes, first roller has to 268a to be clamped and keeps paper M One end the first maintaining part 269a, second roller to 268b have clamp and keep the second of paper M the other end to protect Hold portion 269b.It should be noted that a pair of rolls structures of the first maintaining part 269a and the second maintaining part 269b by clamping paper M Into therefore, paper M can be kept by the rotation of the stop roller after paper M is clamped.

Supply to possess tension force imparting mechanism second and turn the second roller of the paper M in path 249 by rotation to 268b, The first roller rotated is to clamped by 268a.Then, 268a is reached and kept relative to paper M position in the first roller During paper M holding position (position for being distance L1 apart from paper M front end), stop rotation of first roller to 268a, pass through First maintaining part 269a keeps paper M.Afterwards, the second roller is made to rotate 268b by gearshift (not shown) side, while making the One roller is mobile to the approach axis (direction of arrow of dotted line) of from 268a to paper M, makes the first roller to 268a relative to the second roller pair 268b relative position changes.

Then, the second roller is reached to the 268b holding position that should be kept (apart from paper M end in paper M Hold as distance L2 position) when, stop rotation of second roller to 268b, paper M is kept by the second maintaining part 269b.Afterwards, Make the first roller mobile to the approach axis (direction of arrow of dotted line) of from 268a to paper M by gearshift (not shown), can be with Tension force is produced between the first maintaining part 269a and the second maintaining part 269b, tension force is assigned to paper M.

After tension force is assigned to paper M, the second roller is set to reversely rotate 268b by gearshift (not shown) side, side The first roller is set to move 268a to the direction opposite with paper M approach axis.Afterwards, first is reached to 268a in the first roller When roller is to 268a initial position, the first roller is reversely rotated 268a, turned so as to have been assigned the paper M of tension force second After going back to and turning in path 249, conveyed to post-processing unit 300.

In addition it is also possible to the method being discussed further below：The first roller of paper M front is being maintained to 268a to paper M approach axis move the end side for maintaining paper M after predetermined distance to 268b by the second roller in the state of, i.e. the In the state of one roller maintains paper M both ends (front and end side) to 268a and the second roller at predetermined intervals to 268b, Fix position of first roller to 268a and the second roller to 268b, and by only make method that the first roller rotates forward to 268a or Only make the method that the second roller reversely rotates to 268b to assign paper M tension force.

<Possesses the method for operating of the printing equipment of tension force imparting mechanism in temporary location>

Below, the method for operating for possessing the printing equipment 1 of tension force imparting mechanism in temporary location 200a is illustrated.Figure 16 be the flow chart for showing to possess in temporary location the method for operating of the printing equipment of tension force imparting mechanism.In addition, by paper M's Illustrated when as front, using the while relative another side with paper M as reverse side.

First, the presswork signal (step S2-1) for coming from control unit 10 is received.Then, believed based on presswork Number, image (step S2-2) is printed to paper M in printing element 100.The paper M for having printed image is transported to conveying The temporary location 200a in path 218.

Afterwards, in temporary location 200a lead-in path 243, according to come from control unit 10 as printed data Paper M positive and negative printing duty it is poor, selection be not provided with the first of tension force imparting mechanism turn path 248 or set The second of tensioned imparting mechanism turns path 249.That is, the printing duty differences in paper M positive and negative are regulation threshold In the case of being worth more than (such as 30%), it is sent into and sets the second of tensioned imparting mechanism to turn path 249, to having printed image Paper M assign tension force.In addition, in the poor situations for being less than defined threshold (such as 30%) of printing duty of paper M positive and negative Under, it is not necessary to assign tension force to paper M.Therefore, it is sent into first to turn paper M and turns path 248 or the second and turns road Footpath 249.

In step S2-3, whether the printing duty differences for judging paper M positive and negative are more than defined threshold, in "Yes" In the case of, into step S2-4, in the case of "No", it is not necessary to assign tension force to paper M, therefore, turned via first Path 248 or the second is turned after path 249 turned, and is conveyed to post-processing unit 300, into step S2-5.Need It is noted that in the case where tension force need not be assigned to paper M, use and tensioned imparting is set to turn paper M The second of mechanism when turning path 249, can also go back to and turn in the upstream side of tension force imparting mechanism.So, can shorten Fed distance and time of delivery, therefore, it can carry out turning processing at high speed.

In step S2-4, it is sent into and sets the second of tensioned imparting mechanism to turn path 249, pass through tension force imparting mechanism Assign tension force to paper M, and turn and gone back in path 249 after turning second, conveyed to post-processing unit 300, entered Enter step S2-5.Now, it is poor according to the printing duty of paper M positive and negative, become the size of imparting paper M tension force Change.For example, in the case of containing many moisture in poor big, the i.e. paper M of printing duty, paper M tensile strength is weak, therefore, In order to avoid paper M breakage, and reduce the tension force for assigning paper M.In addition it is also possible to the printing according to paper M positive and negative Duty is poor, the time of imparting paper M tension force is changed.For example, in the case where printing duty differences are small, shorten and assign tension force Time.

In addition it is also possible to it is poor according to the printing duty of paper M positive and negative, make the holding position (distance that should keep paper M Position that paper M front end is distance L1 and the position for being distance L2 apart from paper M end) close to or away from.Namely Say, in the paper M region for assigning tension force in the case of paper M front, make the second maintaining part 269b holding position For paper M central portion (distance L2 is elongated).In addition, in the case of the central portion positioned at paper M, make the first maintaining part 269a Central portion with the second maintaining part 269b holding position close to paper M (distance L1 and distance L2 are elongated).Therefore, can be right Assign tension force the area efficient of paper M imparting tension force.

It should be noted that can also be from the drying unit 270 comprising air blower to just by the imparting of tension force imparting mechanism The paper M air blast of power.Paper M is dried by air blast, so as to turn path 249 comprising second after suppressing In transport path 218 dry deficiency caused by the generation of the paper M deformation such as secondary coil, paper M frictional resistance it is upper Rise.

In step S2-5, the paper M conveyed is conveyed to paper piler 328, paper M one end by guide portion 330 Align and be placed in paper piler 328 in side.Afterwards, processing unit 325 is carried out to the paper M in the state of being placed in paper piler 328 Punched on paper M punching processing, paper M is bound by regulation number of pages binding process, by every page or each stacker The post processings such as the displacement processing for opening the position on the width for the paper M that in the width direction staggers to be adjusted.

As described above, the print for possessing tension force imparting mechanism in temporary location 200a according to involved by second embodiment Brush device 1, following effect can be obtained.

The tension force imparting mechanism of tension force is assigned to paper M due to being provided with temporary location 200a transport path 218, Therefore, can conveying midway by tension force imparting mechanism by paper M shape keep and be corrected to it is plane, therefore, can be with The caused temporary location 200a for the curling that paper M can be suppressed is provided.Therefore, in the paper to being discharged from temporary location 200a When M implements post processing, it can reduce caused by paper M curling after printing etc. deforms and stack bad generation.
