Description

The job operation of paper in reel and system of processing

The present invention relates to a kind of paper in reel job operation and system of processing, this system for example can finish prints off generic operations such as image by printing, duplicating or other marking method (hereinafter being generically and collectively referred to as " printing ") on paper in reel (for example paper), and/or folds or regulate the size of size.The present invention especially (not being unique) relates to system of processing, and paper and other material are from the continuous paper in reel on the spool (alleged paper in reel not only refers to common paper among the present invention, also refers to other material) in this system.

Known this system of processing is sending into printer from the paper on the spool, by being printed on a series of patterns on it behind the printer, and then rolls, and is cut into or is folded into various sizes.But this system also exists very big problem, and these problems have seriously limited the efficient of machine, and one of problem is " floor time ".In case the printer adjustment finishes, paper moves, and printing process can carry out very soon.Yet this machine must delay for a long time when printing object or delivering method are done any change.For example, print different patterns, or change the repeat length of pattern, maybe will use different colors, or change folded size, must stop printing this moment.Because there are these problems in known this press structure, make above-mentioned these change extremely difficulty and carry out, the non-operative time (floor time) of machine is more much longer than the operational use time usually.

The structure of known printer also has a problem, be that printer is designed to special printing, machine is designed to an integral body, this just means in practice, if during machine customer wants to carry out to come more complicatedly than the operation that can carry out now on his machine operation, he must carry out big repacking or buy a cover new engine.

The present invention has overcome (or having solved at least to some extent) these problems, design the paper in reel system of processing, (can be described as " awing ") can carry out many changes when this system moves, but also has standardized advantage, and this system can enlarge its working ability where necessary.

The present invention relates to the relation of printing mechanism and paper in reel thereafter processing.Printing industry develops at both direction.One of them direction relates to the processing of elongated coil coil paper, and example is as described above), and another direction relates to the processing of sheet-fed material.In general, all there are some problems in each equipment, and the worker of this area generally concentrates on attention themselves technical field.Yet it has been recognized that the folding problem that occurs on the elongated coil coil paper manufacture field can solve effectively with the technology of sheet-fed manufacture field, this technology has developed into the product that is used for processing single sheet paper printer.Thereby, the present invention proposes the paper of web press output is cut into sheet-fed, and send into the sheet-fed folding system.

By the present invention, a kind of method of processing at least one volume stock roll coil paper is provided, be included at least one volume paper in reel and print, the reel tube that printed or each paper in reel are cut into many sheet-feds with the mode that is printed with the certain hour relation, with folding each sheet-fed of folder, the action of folder depends on that sheet-fed arrives the time of folder, and wherein material is a continuous movement to beginning folding sheet-fed from printing before.

The invention provides the method for at least one volume stock roll coil paper of another kind of processing, be included at least one volume paper in reel and print, the paper in reel of longitudinal folding printing or each paper in reel, paper in reel or each paper in reel are cut into many sheet-feds with the mode that is printed with the certain hour relation, with folding each sheet-fed of folder, the action of folder depends on that sheet-fed arrives the time of folder.

The present invention also provides the method for at least one volume stock roll of another kind of processing coil paper, be included at least one volume paper in reel and print, the paper in reel of longitudinal folding printing or each paper in reel, paper in reel or each paper in reel are cut into many sheet-feds with the mode that is printed with the certain hour relation, with folding each sheet-fed of folder, the action of folder depends on that sheet-fed arrives the time of folder.

The invention provides the method for at least one volume stock roll coil paper of another kind of processing, comprise at least one volume paper in reel of printing, cross-perforating on the paper in reel that printed, paper in reel or each paper in reel are cut into many sheet-feds with the mode that is printed with the certain hour relation, with folding each sheet-fed of folder, the action of folder depends on that sheet-fed arrives the time of folder.

The present invention also provides a kind of paper in reel system of processing, comprise the equipment that is used for printing continuously at least one volume stock roll coil paper, be used to carry the device of the paper in reel that printed, with the device that is used for conveying single paper, carry the device of the paper in reel that printed the paper in reel that printed to be transported to continuously the device that is used for paper in reel is cut into many sheet-feds, the action of this cutting means and printing device have the regular hour relation, the device of conveying single paper is transported to the device that folds sheet-fed continuously to sheet-fed, and the action of folding device depends on that sheet-fed arrives the time of folding device.

The present invention also provides a kind of paper in reel system of processing, comprise: the equipment that is used to print at least one volume stock roll coil paper, the device that is used for longitudinal folding paper in reel or each paper in reel is used for that paper in reel is cut into the device of many sheet-feds and is used for the device of folding sheet-fed.

At first with reference to figure 1, paper in reel involved in the present invention (being paper in this example) system of processing comprises three parts.First briefly represents by 1, and this part comes out paper and is transported to printing element 3 and optional drying unit 4 with the form of reel paper web 2 unreel from one or more paper spools.As shown in Figure 1, reel paper web 2 is realized right-angle steering by a turner bar 5, after printing element 3 and drying unit 4.For simplicity, reel paper web 2 changes 90 ° of angles again by another turner bar 6 again, delivers to one again and cuts and fold mechanism (briefly being represented by Fig. 7).Through suitable printing, cut and fold the sheet-fed of processing and send to along the direction shown in the arrow 8 and pile up.Certainly, can arrange paper in reel input block 1, printing element 3, drying unit 4 arbitrarily and cut and folding device 7, but practical structure is arranged and depended on space and other similar limiting condition.

As mentioned above, the present invention relates to the various improvement of the parts of this system.

Fig. 2 shows an embodiment of the equipment 1 that is used to carry and send to the material (for example paper) on the spool, it comprises a connector unit and a series of movably scroll support represented with piece number 10, they take spool transport trolley 11,12 form (although only illustrating two, available more).Each transport trolley is included in a base 13 with wheel or castor 14, the lifting of base support spool and load bearing arm.Be loaded with the spool 16 of a paper on the arm 15 of each transport trolley 11,12, the axis of arm is roughly level, and the reel paper web can be by being drawn out and being transported to connector unit 10 on the reel like this.Each transport trolley all has control setup, the unreel of contained spool on the arm 15 of control example such as transport trolley 11,12.The front end of each transport trolley 11,12 can be equipped with and the interconnective device of another transport trolley trailing edge, and they can not connect yet and are in line.So just, can below connector unit 10, order promote transport trolley 11,12, make that another volume just can be brought into use when a coil paper used up.The scheme of the transport trolley of this paper spool that is in line can be used under high quick coupling situation, and is then more superior during zero-speed, the equipment that is used for the latter shown in Figure 2.

Transport trolley is used for transporting and returning from the machine of storage at, and the scroll rack during as unreel, but the transport trolley serial arrangement is on the close position of connector unit, and it is removable, make that (on transport trolley 12) next volume paper in reel (on transport trolley 11) can arrive station when a volume paper in reel uses up, reel paper web in the running on the transport trolley 12 roughly is identical inclination angle during by roller 17 in connector unit 10, make each joint afterwards that one predetermined shearing length is all arranged like this and all on the same one side of paper web.This has reduced the carrying and the process load of spool.Make machine in this section with other machine operation part to be connected work more flexible; Make machine and material movement layout better, particularly under the situation that a part need be unloaded from machine with the spool of crossing or scrap.

As shown in Figure 2, deliver to a Suspension System 20 from the reel paper web 18 of fwd transport trolley 12 by roller 17 and pressing plate 19, Suspension System 20 has a roller 21, and this roller can move between diagram solid line position and dotted line position.The spool 16 that is loaded with next reel paper web 22 of preparing place in operation is installed on second transport trolley 11, but its front end is contained on the swing unit 23.But swing unit 23 has a compression system 24, is fixed at the front end of this system's inner drum paper web 22, preferably fixes when swing unit 23 is in retracted position shown in the dotted line.

When 18 runnings of first volume coil paper, roller 21 moves to the position shown in the solid line, also has quite a lot of a part of paper to move in suspension unit like this.When the reel paper web of pulling out 18 when terminal or when wanting to change paper in reel, stop to suspension unit input reel paper 18, but because roller 21 moves towards dotted line position, paper continues output (along the direction of arrow 25 indications) from transport trolley 12.Because the part transfixion of paper in reel 18 contiguous pressing plates 19, swing unit 23 swing by graphic solid line position until linkage unit 24 with till pressing plate contacts, so will scribble lining cement above the reel paper web 22() be pressed onto and finish joint on the reel paper web 10 No. one time.By cutter 26 severings, return by swing unit 23 below pressing plate 19 for reel paper web 18 then, and reel paper web 22 is admitted to suspension unit 20 again, and roller 21 is moved back into the initial position shown in the solid line again.

Delivery roller paper web 18,22 enters connector unit 10 does not depend on the axis of spool 16 to the accuracy rate of printer by suspension unit 20 alignment precision.If the axis of spool 16 is not accurately perpendicular to the indicated direction by suspension unit 20 outputs of arrow 25, reel paper web 18,22 just has the danger of in printer foldover or " exceeding the bounds " (for example sideslip) so.In order to prevent this phenomenon, the registration device of the spool 16 of transport trolley 11,12 and joint below need be set.Adoptable a kind of like this alignment device has been shown among Fig. 3 a and the 3b.

Accurately vertical with the reel direction of web movement and guarantee that the axis of spool is correct to the distance of splicer 10, two kinds of different alignings of needs for the axis that guarantees spool.Fig. 3 a shows first kind of alignment device.As shown in the figure, outside face at one of them arm 15 of transport trolley 11 is rotatably mounted with two guiding balls 30, the outside face of another one arm 15 is equipped with a guiding ball 31, and guiding ball 31 is not only rotatable and can be to the outside face of arm 15 elastic load in addition.(as shown in Figure 2) ball 30,31 contacts respectively with the pair of guide rails 32 of transport trolley both sides when transport trolley 11 passes through splicer 10 belows.Two balls 30 guarantee that the remainder of cooresponding arm 15 and whole transport trolley accurately collimates with guide rail 32, and spring-loaded roller ball 31 guarantees the adjustment of the slight variation on whole transport trolley width.3 contacts of ball 30,31 can accurately collimate transport trolley with guide rail 32, and guide rail 32 can accurately collimate with the sense of motion of reel paper web.

As above with reference to what Fig. 2 addressed, transport trolley is installed on wheel or the castor 14, and theoretically, if ground 33 is very flat, wheel is done very accurately, and the axis that then can guarantee spool 16 is perpendicular positioning accurately.And in fact this accurate location can not be accomplished.Therefore among Fig. 3 b a kind of method that obtains this perpendicular positioning has been shown.Each transport trolley 11 has a pair of support ball post 25 in its both sides, chute 36 roughly is housed on the ground below the splicer 33.When the front-wheel 14 of transport trolley moves on on the chute 36, to support ball post 35 and cooperate with guide rail 37, a guide rail 37 respectively is equipped with in transport trolley 11 both sides.Guide rail 37 tilts at the sense of motion of transport trolley 11.When transport trolley 11 moved, the effect of supporting ball post 35 and guide rail 37 was that the trailing wheel of transport trolley 11 or rear truckle 14 33 are risen built on stilts from ground.Therefore the perpendicular positioning of the spool 16 on transport trolley and the car is mainly determined by guide rail 37.

When transport trolley moves forward, support ball 35 and move to the position by the position A among Fig. 3 b.

Said system transport trolley 11 by splicer 10 below in the moving process, the arm 15 on the transport trolley 11 need be locked on the appropriate location.The method that also available suitable stop motion mechanism stops when making arm 15 move to a certain definite position reaches the accurate perpendicular positioning of spool, although this method is not optimum.

Fig. 3 a and 3b show the embodiment of the transport trolley that low spool is installed that is in line like this, and this embodiment is first aspect of the present invention.

Described with reference to figure 1 as mentioned, the reel paper web is transported to printing element 3 then and goes, and Fig. 4 shows an embodiment of printing element 3 according to a second aspect of the invention, and this embodiment is a paper in reel offset perfector.As shown in the figure, printer has three frameworks 40,41 and 42, a pair of B-B formula blanket cylinder 43,44 and a pair of plate cylinder 45,46 are arranged on each framework, form a forme at the plate cylinder outside face, forme respectively with blanket cylinder 43,44 in cooresponding one contact: promptly each framework can comprise one " printing to ".Usually plate cylinder has identical diameter with blanket cylinder, but known also have the plate cylinder girth be cooresponding blanket cylinder girth half.As shown in the figure, framework 40,41 and 42 tight adjacency, it is small-sized that this arrangement makes that framework is arranged.Can also be with framework 40,41,42 are spaced.Reel paper web 2 is walked around roller 47 and is passed through between a pair of blanket cylinder 43,44 from each framework 40,41,42.Preferably framework 40,41 and 42 basic stacked vertical are arranged, but also can substantial horizontal be arranged, framework is made movably on perpendicular to the reel web direction.Be loaded with the image of preparing to be printed onto on the reel paper web 2 on the plate cylinder 45 and 46, be transferred on the paper web by blanket cylinder (" offset printing " printing).This process is known.

As shown in Figure 4, the paper in reel both sides are provided with one and comprise printed medium, for example inking and damping conveyer 48,49, the unit.Inking and damping conveyer 48,49 can move in the vertical direction separately or together, and comprise a release mechanism respectively so that said apparatus vertical shifting (comparison device 48 and 49).

When printing process begins, inking and damping conveyer 48,49 vertically move go with framework 40,41 and 42 in an alignment.Inking and dampening roller 50 enter engagement by the mechanism and the plate cylinder that can guarantee proper operation pressure and figure.As shown in the figure, inking and damping conveyer 48,49 are located at the both sides of reel paper web 2 and are that three frameworks 40,41 and 42 are shared.If with framework 41 printing, conveyer 48,49 just inking and dampening roller 50 are delivered to framework 41 on two plate cylinders 45 and 46 position contacting on, printing process begins then.When printing process finished, inking and damping conveyer 48,49 were got back to its open position (among the figure shown in the piece number 48) again.Conveyer 48,49 vertically moves, up to other two frameworks 40,42 in one adjacent till.Then inking and plate-moistening roller again with another framework 40 or 42 on plate cylinder 45,46 enter contact condition, a new printing process begins again.

Also having a kind of may be exactly that framework perpendicular movement and toter keep transfixion, but this is with more difficult the reaching of method of machinery, notices that this scheme makes the framework can " at machine " storage, and this is more effective than known scheme.

One with Fig. 4 in the supporting drive system of printer will be described to reference to figure 5 and 6 below.Shown in the planar view among Fig. 5, inking will be contained in one with the damping toter can be on the support frame 51 that printer mainframe 52 moves, and mainframe is again by end frame 52a idler pulley 43,44,45 and 46.The horicontal motion mechanism of inking and damping conveyer 48,49 is not shown, but the limiting device 53 that is installed on the support frame 51 has been shown among Fig. 4, is used to limit this horizontal motion.

Support frame 51 with and on the inking and the perpendicular movement of damping toter be to control by the elevating motor of installing on the support frame 51 54.Electrical motor 54 drives one 55, and this axle connects across support frame 51 and by bevel gear 56,57 and two axles 58,59.Axle 58 drives a miniature gears 60 that is installed on the mainframe 52 and rotates, and miniature gears 60 is meshed with tooth bar 61.Equally, axle 59 drives two miniature gearss 62,63 that are installed in mainframe 52 relative sides, and this miniature gears meshes with cooresponding tooth bar 64,65 respectively again.Electrical motor rotates and axle drive shaft 55,58,59 like this, cause miniature gears 60 thus, 62,63 along cooresponding tooth bar 61,64,65 last or following motions, drive support frame 51 relative mainframe 52 last or following motions thus, in this structure, used 3 installations, but also can be by the axle 58 on mainframe 52, the more miniature gears of configuration on 59, tooth bar pair are realized or more multiple spot installation at 4.The accurate perpendicular positioning of support frame can reach by the accurate control to electrical motor 54, or sees Fig. 4 by a limiting device 66(is installed on mainframe 52) reach.Limiting device 66 can be spring-loaded, and when support frame 51 moved it, it just ejected from mainframe 52 like this, and support frame 51 just drops on the position of limiting device.Very clear, when support frame 51 moved downward, for example, the station to framework 40 in Fig. 4 went; Limiting device 66 must be depressed to allow support frame to pass through.

Narrate the driver train of cylinder 43,44,45 and 46 now.In fact, the driving device of the driving device of cylinder 43,45 and cylinder 44,46 is identical, will only relate to the driving device of cylinder 43 and 45 below.

Extend upward along mainframe 52 for one 67, and can move manyly on mainframe, a gear 68 is installed on it, gear 68 is gone up the gear of installing 69 and is meshed to rotate with one, is extended with a worm screw 71 along axle 70, and worm screw 71 is meshed with worm gear 72.An axle 73 is fixed in the hole of worm gear 72, and is supported frame 51 by a strut member 74 and supports.At axle 73 the axle head away from reel 43,45 one cylinder 75 is arranged, cylinder 75 can make axle 73 make axial motion.The other end at axle 73 has a clutch-plate 76, and clutch-plate 76 and the clutch-plate 77 from plate cylinder 45 extended minor axises 78 mesh.Clutch- plate 76,77 and their coupling spindle 73,78 pass a hole 79 on the mainframe 52.In the end of plate cylinder 45 gear 80 is arranged, gear 81 engagements on gear 80 and the blanket cylinder 43.

Like this when axle 73 by cylinder when mobile, just make clutch- plate 76,77 enter engagement, propulsive effort from axle 67 passes through gear 68,69, axle 70, worm screw 71, worm gear 72, axle 73, clutch- plate 76,77 and minor axis 78 are sent to printing cylinder, and be delivered to blanket cylinder by gear 80,81 by printing cylinder.

When axle 73 is moved by cylinder and makes clutch- plate 76,77 jump out of meshs, come without any power transmission.Can think that further this move of axle 73 enough makes clutch-plate 76 leave hole 79, make on the whole support frame device relatively mainframe 52 move on to the station adjacent with another framework.The preceence of this device is not carry any power to go over to the cylinder on the framework that is in off working state, therefore can dispose safely, for example, changes the forme on this.Because the cylinder transmission device is along with the motion of inking and damping conveyer, any specific of non-printing state is accidental in the time to drive them so can not be at cylinder.

The power-transfer clutch of being made up of clutch- plate 76,77 has another effect.Clutch- plate 76,77 constitutes " unique position " power-transfer clutch, makes power-transfer clutch be scheduled to sync bit between plate cylinder 45 and the corresponding driving system.Do not consider the initial position of plate cylinder 45 like this, its rotation will be synchronous with the rotation of axle 67.

Sometimes, need to change axle 67 and plate cylinder 45 synchronously with in advance or postpone printed image with respect to main drive system.For achieving the above object, worm screw 71 is driven along axle 70 by a straight line motion actuator 82 and moves, and this linear motion actuator just often makes worm screw 71 keep motionless on axle 70.The mobile worm gear 72 that makes of worm screw rotates, and worm gear makes the position rotation of plate cylinder relative drive shaft 67 again by axle 73 and clutch-plate 76,77.The motion of worm screw 71 also can be from an electrical motor or hydraulic ram.Another plate cylinder 46 can green phase with respect to the motion of axle 67 with method obtain, can be at the same time or separately obtain by the motion of plate cylinder 45.

The inking on inking and the damping conveyer 48,49 and the drive system of plate cylinder 50 will be narrated with reference to Fig. 6 below, the view that though Fig. 6 is Fig. 4 to be equal to, but for clarity sake, framework 40,41,42 has been omitted, and above-mentioned conveyer is moved with respect to mainframe 52 by the power driven support frame 51 from elevating motor 54.

As shown in Figure 6, an end of axle 70 is equipped with gear 83, and the other end is equipped with gear 69, and the centre is a worm screw 71.These gears 83 are meshed with another planetary train 84 of installing on 85.The two ends of axle 85 are separately installed with gear 86, gear 86 and gear 87 engagements, and the driving system in gear 87 and inking and the damping unit meshes in a conventional manner.Axle 70 just has been bound up with axle 85 like this, and is bound up with reference to the axle drive shaft 67 that Fig. 5 discussed with top, axle drive shaft 67 head rolls 43,44,45,46, and drive inking and dampening roller 50.

; this diameter that also depends on plate cylinder 45,46 synchronously; if and printer has the cylinder of two kinds of different-diameters; above-mentioned driving system only is applicable to a kind of cylinder of diameter; and when inking and damping unit 48,49 move to the framework of the cylinder that has different-diameter, whole printing will lose synchronously.The scheme of Fig. 6 has been used a kind of auxiliary motor 88 that power is delivered to axle from planetary train 84 85 to overcome the problems referred to above.The rotating speed of auxiliary motor 88 is detected, discriminator 89 of testing result input, and this device compares (paper in reel is by passing through between the roller 90) to the rotating speed of plate cylinder and roller 90.These rollers 90 equally also can be got in touch with planetary train.If find that driving system is asynchronous, just allow electrical motor 88 quicken or deceleration, till synchronously.The speed change of electrical motor 88 makes axle 85 change rotating speed by planetary train 84 like this.

Fig. 6 shows the further feature of this system,, drives 91 drivings of axle by the extension of printing element outside of the axle 67 of forme and blanket cylinder that is.Like this, also can add more printing element, or as shown in Figure 6, can connect the tapping and plugging machine of a pre-folder 92 or cut the tapping and plugging machine or the guIllotine of unit axle 67.These will be described in detail in the back, but can see that main shaft 91 has gear 93, and gear 93 drives the axle 94 of pre-folder 92 again, and axle 94 drives tapping and plugging machine 95 again, also can add planetary train 96 in this system, and mix discriminator 89.

As shown in Figure 4, a pair of inking and damping conveyer 48,49 are that three frameworks are common.Usually, three frameworks can have different images on their plate cylinder, perhaps even the diameter difference of cylinder.By changing the method for framework, can change printing length.Other scheme also is feasible, an embodiment has been shown among Fig. 7, comprising four frameworks 100,101,102,103, each is all similar to the framework 40,41,42 shown in Fig. 4, reel paper web 2 is by passing through in the middle of the framework 100,101,102,103, be provided with four inkings and damping conveyer, a pair of 104,105 of top is used for two frameworks 100,101 of top, and a pair of 106,107 of below is used for two frameworks 102,103 of below.By this method, for example, might print two kinds of different colors, and still keep the possibility that changes image and/or repeat length with the printing cylinder of same diameter.Equally, as shown in Figure 7, the cylinder on the support can have different diameters, and for example, the diameter of the cylinder on the framework 100,102 is littler than the diameter of cylinder on the framework 101,103.Printing element shown in Fig. 7, disposed four frameworks except discussed above that other is roughly similar to the printing element among Fig. 4, and have a similar driving system of being narrated among Fig. 5 and Fig. 6, therefore will omit the further detailed description of the mechanism of Fig. 7.

Characteristics of this system are to have set up additional frame, and the inking and the damping transmission system 48,49 that add when possibility, have so just increased the quantity of different presswork.

Above is to make perpendicular movement with respect to the framework of row's vertically stacked with reference to inking among the embodiment that Fig. 4 to Fig. 7 narrated and damping unit.Equally, also can be horizontally disposed with, promptly framework is lined up a row of level, and inking and damping unit be with respect to these frame movements, and prints on framework.Can adopt one or two inking and damping unit, the driving of plate cylinder and inking and damping unit is still the same with described vertical cell (being shown in Fig. 5).Difference only is and can drives plate cylinder with the horizontal power axle with the main power shaft parallel running.Pass the power of coming from main power shaft and import by a vertical axis, this vertical axis connects main power shafts and horizontal shaft by two pairs of bevel gears.

As previously discussed, whole row's framework is fixed, and inking and damping unit then are movable.Because the present invention is that it is moving so inking and damping unit are fixed framework to be raftinged by relative motion.Make frame movement can take any way, as roller, guide rail, or air pressure jack, the motion of the plate cylinder on the framework can realize by the monodentate power-transfer clutch that reference Fig. 6 was described.Adopt the advantage of movable framework to be that inking and damping unit fix, therefore, the transmission of system is also fixed.But common people think makes frame movement than making inking and damping block operation difficulty.

Fig. 8 and Figure 9 shows that an alternative embodiment of the invention, it is related is exactly the inking fixed and the framework of damping unit and motion.This embodiment has 4 frameworks 111,112,113,114, and they form a rotating disk 115.As shown in Figure 8, each framework all has a pair of plate cylinder 116 and a pair of blanket cylinder 117, and their form is similar substantially with the forme and the blanket cylinder of the framework in embodiment illustrated in fig. 4 40,41,42.But as can be seen from Figure 8, the forme of framework 111,113 and blanket cylinder 116,117 are littler than the forme and the blanket cylinder 116,117 of framework 112,114.This just makes framework 111,113 and framework 112,114 have different some repeat lengths.

Paper in reel 2 enters printer by roller 118,119, and moves along a horizontal path by two 112,114 in four frameworks 111,112,113,114 of rotating disk 115.This rotating disk rotatably is supported on the frame 120, and 121 of second frames are supporting one or two inking and damping unit 122(can be more clearly visible an inking and damping unit from Fig. 9).When an inking and damping unit were housed, it preferably was positioned at the paper in reel of rotating disk 115 and imports a side.When two inkings and damping unit were housed, they were usually located at the relative both sides of rotating disk 115, so that framework 111,113 or framework 112,114 can be driven.

Fig. 8 and printer shown in Figure 9 can be with a kind of work in several forms.For example, can only carry out presswork with framework 114, framework 112 can be prepared another kind of different presswork.After finishing with the presswork of framework 114, the blanket cylinder 117 on the framework 114 can be removed on the paper in reel 2, and stops the driving to this framework, the blanket cylinder on the framework 112 117 is moved on to paper in reel to contact then, and drives framework 112.Just can carry out presswork and framework 114 is prepared then with framework 112.If framework 112 and 114 has identical print repeat length or printing diameter, just may carry out the printing of two kinds of colors in tandem with framework 112 and 114.

When using framework 111,113 instead and printing, a motor 123 drives rotating disks 115, makes it rotate 90 ° on frame 120, and framework 111,113 has just been aimed at paper in reel 2 like this.(not shown) can classification be realized in the accurate location of rotating disk.This rotation of rotating disk 115 means that paper in reel 2 must disconnect to be transformed into another from pair of frames on the framework.Therefore, just as shown in Figure 4 embodiment is insuperior for present embodiment.As arrow 124 indications, rotating disk 115 can clockwise rotate or rotate counterclockwise on demand.

Narrate Fig. 8 and driver train embodiment illustrated in fig. 9 now.Referring to Fig. 9, this can be connected to axle 125(on the drive system of the whole print system of being discussed as reference Fig. 6) drive an axle 127 by gear 126, drive the driver train 129 of an inking and damping unit 122 again by gear 128.Driver train 129 can be with similar with reference to the mechanism that Fig. 6 narrated, i.e. transmission can realize that planetary wheel then moves to reach the synchronous of driving by an additional motor 131 by planetary wheel 130.

Also has a gear 132 on the axle 127, its same worm screw 133 connection, same again worm gear 134 effects of worm screw 133.This worm gear rotates an axle 135, and its end is a linear actuators 136, and the other end is a power-transfer clutch 137.Power-transfer clutch 137 same axises 138 link, and this root axle drives the plate cylinder 116 on one of framework 111,112,113,114.Like this, the driving of present embodiment is haply with similar with reference to what Fig. 5 narrated, so its operation just becomes conspicuous.

Illustrate to draw that as the right side of Fig. 9 axle 127 also can stretch to the opposite side of rotating disk 115, to drive another inking and damping unit (not shown).

Shown in Fig. 4 (or Fig. 7 or 8 and 9) one of mechanism further improve be about cylinder at framework 40,41,42(100,101,102,103 or 111,112,113,114) in installation.Obviously, if cylinder is installed in a usual manner, when changing framework, all need spended time accurately to adjust the printing position at every turn.Therefore, a third aspect of the present invention is the mechanism that can easily blanket cylinder be moved on to or move apart their accurate contact position about.After their contacts, just can print.After they moved apart contact, they just can not hinder next step, for example adopt the printing of other framework.Also have, can remove a framework from the printing position, and replace it, and carry out quickly and easily locating in the accurate movement with another framework that has the different size cylinder.By this way, just can machine repeatedly be changed with minimum floor time.

Figure 10 shows that an embodiment of this system, be used for blanket cylinder 43,44 is moved on to or move apart contacting with paper in reel and the cylinder adjacent with them.Solid line is represented the position of cylinder when printing, the position when dotted line is represented not print.A blanket cylinder 44 is by the gear 79 that meshes together, 80(sees Fig. 5) shift onto with the plate cylinder 46 that is associated with it and contact, also lean against simultaneously on another blanket cylinder 43 by (paper in reel just nipped between blanket cylinder 43 and 44 the good contact when guaranteeing printing).Then, blanket cylinder 43 leans against on its plate cylinder 45.Usually, left a very little gap at 43,44 o'clock at the installation blanket cylinder, therefore when blanket cylinder 44 is pulled to the cylinder contact that is adjacent together, since with the plate cylinder that is associated with them and and their coefficient blanket cylinders between contact pressure, two cylinders all can automatically be positioned oneself on its accurate printing position.

Make blanket cylinder 43,44 contacts, one (cylinder 44 among Figure 10) in them should be movable, and their axle moves between position B and A.This can be achieved like this, and for example the termination with cylinder is placed in the groove of strut member, and an end of groove is corresponding to the drum shaft at position B, and the other end is processed to make drum shaft in these groove both sides single-degree-of-freedom to be arranged when the A of position.When not printing, drum shaft is pushed to position B by a loaded piston 140, i.e. the position at blanket cylinder 44 places represented of dotted line.At this moment, blanket cylinder 44 has also all broken away from another blanket cylinder 43 with its plate cylinder 46 and has contacted.

Another blanket cylinder 43 is installed on the swing strut member 141, and swing strut member 141 makes that drum shaft can be along a movement in a curve that limits in a macropore (not shown).The position of the axle the when edge in this hole does not influence blanket cylinder 43 with plate cylinder 45 contact, but limited its amount of movement when removing plate cylinder.Like this, when blanket cylinder 44 moves to position B, just can produce a gap between blanket cylinder 43 and the plate cylinder 45, and owing to blanket cylinder 43 can move with cylinder 44, between blanket cylinder 43 and 44, also can produce a gap, but can not be as far as disengaging.Similar functions also can realize by the strut member that blanket cylinder 43 is installed in a groove, can make it with plate cylinder 45 contacts, has limited being separated from moving of plate cylinder again.If there is not thing to make blanket cylinder 43 keep contact with plate cylinder 45, it will do disengaging movement on the swing strut member 141 at it under the effect of a power (can be provided by gravity) that makes its separation.Make the power of its separation require to be no more than a critical value.If the gravity (or other power) that acts on the roller 43 has surpassed this value, a spring 142 or other bias unit (for example cylinder) that this separating force will be applied on swing strut member 141 weaken.

As shown in figure 10, blanket cylinder 44 also is installed on the frame 143, and frame 143 same levers 144 link together, and lever 144 can rotate around point 145.When lever 144 by for example pressure system 146 in figure during the motion of position shown in the solid line, a power just is applied on the blanket cylinder 44, and the pressure that makes its axle overcome piston 140 leaves position B, and to move to position A(be the printing position).Blanket cylinder 44 props up its plate cylinder 46, simultaneously also with another blanket cylinder 43 contacts, and makes it also move to 45 contacts of another plate cylinder.Just can get accurate localization and pressure to the end (and end the dependence upon their mounting groove or Kong Ze effect) by application force between two blanket cylinders and their adjacent rollers and the controlled power that they are moved into place.

Like this, when " opening " position, by making in the cylinder one move on to or move apart the device in a printing position and making another cylinder limit the interior because counteraction of power of distance and the Fu device one, when " pass " position, by the restriction in groove or hole, also can realize disengaging and contacting again of printing at an easy rate very soon even if when printing, change a different framework.In other words, this system can realize that pressure loads and self-orientation.Ideally, cylinder should operation on a continuous surface, and this preferably realizes by idler (will discuss afterwards).

Therefore, can realize continuously printing, and make when changing framework can be soon and easily by desired precision location with reference to the machine that Fig. 4 to Figure 10 discussed.This is very important concerning shortening floor time.Mechanism shown in Figure 4 is specially adapted to single color printing (comprising black).It also is applicable to colored printing, though can need a plurality of frameworks and inking and damping transmission system this moment this moment because public inking and damping transmission system causes difficulty.

Figure 11 is specially adapted to cylinder design of the present invention with Figure 12 shows that.Each cylinder all has the tube core 150 of an intended size, can load onto the rim unit of different-thickness on the tube core as required.Figure 11 shows that a cylinder that thicker rim unit 151 is housed, Figure 12 shows that a cylinder that thin rim unit 152 is housed.Changing rim unit just can change the effective diameter of cylinder and needn't take off a core 150 from printer.Rim unit 151,152nd, erosion resisting (otherwise the Aci-Jel in the fountain solution can corrode it), and also just be easy to keep in repair after taking off rim unit.

See Figure 11 and 12, a forme 153 is arranged on the wheel rim 151,152, it is fixing by clip 154,155, makes forme 153 around stretching tight on cylinder.From Figure 11 and 12, be also shown in the end ring 156 and the gripping mechanism 157 of cylinder end, in order to rim unit 151,152 is fixed on the core 150.Ring 156 also plays the effect of a supporting member, to guarantee the smooth rotation of foregoing cylinder.It should be noted that ring 156 is thicker slightly than rim unit 151,152, their outer radial face is just fully corresponding with the outside face of forme 153 like this.

After web printing is intact, another aspect of the present invention will work.In most of the cases, becoming the folding of paper of paper in reel form is (though may realize that one or more are longitudinal folding, this will narrate hereinafter) that is difficult to, and the folding system of loading onto several complexity of minority in web press output place is possible.On the other hand, the technology of folding page has a variety of, and for example gate-type is folding, and multilayer is laterally folded and longitudinal folding, and Figure 13 and 14 is depicted as wherein two kinds.

Figure 13 shows that a kind of mechanism that is known as knife folding machine, in this mechanism, paper 160 passes through on the roller 161,162 of a pair of contrarotation.When paper 160 was fixed on this position, a cutter 163 moved downward and forces paper 160 to enter " roll gap " 164, and paper is just folded up securely.Paper 160 is made next step purposes from pulling out between the roller 161,162 downwards then.Cutter 163 is connected with an electro-optical tubes usually or whether similar detector has paper 160 below the detection cutter.Like this, folding operation just gets up synchronously with the arrival folder of paper, rather than synchronous with the presswork of last operation.

Figure 14 shows that a kind of mechanism that is known as the buckle-fold device, in this mechanism, paper 170 passes through between the roller 171,172 of first pair of contrarotation, and its front end is run into an inclined-plane 173.The effect of roller 171,172 forces paper 170 along the inclined-plane 173 upwards, runs into a baffle plate 174 up to its front end, and the position of baffle plate 174 is according to required folding position decision.After paper was run into baffle plate 174, it just can not continue along the inclined-plane upward movement, so the effect of roller 171,172 forces paper 170 to enter roll gap between roller 172 and another roller 175.It is folding accurately that this just makes paper produce, and then, because the effect of roller 172 and 175, it moves downward up to meeting another baffle plate 177 along another inclined-plane 176 again.In this position, paper 170 is subjected to the effect of roller 175 and 178, and another roll gap between them makes paper be folded again.Can also make paper be sewn on vertical perforation of the paper after folding by the perforating roller between the roller 179.Like this, it is folding and to the perforation of paper that system shown in Figure 14 just can carry out continuous transverse.Several this unit that have one or two inclined-plane are set, just can realize any amount of horizontal folding.If change the sense of motion of paper between a buckle folding machine and another buckle folding machine, the folding of vertical and horizontal just can both have been realized.Yet general folding for the first time all is laterally folded, otherwise just needs supplementary equipment therefore.Equally, paper 170 folding is the time decision that arrives folding machine according to its, rather than according to time of presswork.

Also can adopt the folding machine of a kind of cutter formula and fence type combination.

Referring now to Figure 15 and 16,, the paper in reel 2 that comes out from a web press (for example shown in Figure 4) is cut into sheet-fed by a paper cutting device 180.Figure 15 is the transparent view of this device, and the paper in reel 2 that comes out from printer 2 makes it turn over 90 ° by a bar 6 earlier, and this narrated with reference to Fig. 1.Certainly, this not necessarily, the route that paper in reel arrives paper cutting device 180 can be straight as shown in phantom in Figure 15 like that also.Paper cutting device 180 can be by a drive shaft public with printing mechanism, and Fig. 6 narrated as reference, and promptly the paper cutting device 180 among Figure 15 and 16 is corresponding to the element among Fig. 6 91.Can also be provided with one as dryer unit with reference to Fig. 1 narrated.After paper cutting device 180 was cut into page (sheet-fed) with paper in reel 2, just by a folding machine 181, this folding machine can be a sort of buckle folding machine for example shown in Figure 14, also can adopt knife folding machine shown in Figure 13 for they.The something that should note is, the speed that the speed of the paper in reel that comes out from printer can be handled greater than known paper folding system possibly is so the paper that stream can be brought is diverted to two or more routes.In this example, system is equipped with a diverter 183, so a part of paper is directly delivered to folding machine 181, another part then is diverted to another folding machine 182.184,185 places can also further change of direction in the unit.It is known that the two-way of this paper is handled, and just there is no need here to be described in a more detailed discussion.Obviously, according to the purposes of paper, can carry out the folding of any number of times.

In fact, as previously discussed, folding for the first time in the paper feed system generally all is laterally folded.Figure 16 shows that a kind of first time is with regard to longitudinal folding straightforward procedure.This is particularly important for the thin paper that the buckle folding machine of using is not too easily as shown in figure 14 handled.The paper in reel 2 that comes out from printer and (possible) drier leads to a leg-of-mutton stereotype press 190, therefore, a slit is arranged when paper moves downward a pair of deflector roll 192(from a roller 191 between them) time, paper is just by longitudinal folding.Like this, the paper that passes to a total label and be 193 buckle folding machine once by longitudinal folding mistake, therefore just mistake appears in not conference when folding.Equally, should assemble upper slitter or similar paper cutter 194 on the position before paper in reel enters buckle folding machine 193.

It is above that what narrate all is directly this paper to be folded.But, laterally foldedly carry out easily in order to make, also can last horizontal perforating mechanism 195 be installed in the front of cutter or other paper cutter 194.Also have, can pass hole 197 by continuous perforation wheel 196, it is shown in Figure 16 longitudinal folding to help so just can to pass vertical hole with web press.The main drive shaft of the print system of being narrated when in addition, this perforation wheel 196 can be by reference Fig. 6 drives.Equally, any longitudinal foldingly all can carry out continuously.Because air can be discharged from the hole in folding process, so perforation also helps to improve the quality.
