A reciprocating paper-transferring tooth system 20 is followed after preceding seamed edge backstop 17, and this paper-transferring tooth system flows to 4.2 the past of paper seamed edge backstop 17 grippers 21 of conveying cylinder 22.Paper-transferring tooth system 20 can be by electrical motor 23 controls.In the transport path of going to conveying cylinder 22, a retaining pawl 24 is movable, and paper 4 is stopped.Conveying cylinder 22 drives by train of gears, wherein by the motion of corner transmitter 25 sensing rotation.Corner transmitter 25, electrical motor 23, retaining pawl 24, detector 18, negative pressure source 8, belt speed sensor 16, controller 15 and suction nozzle 3 are connected with control setup 26.
Fig. 2 illustrates the birds-eye view of sheet feeder platform 5.Be provided with two detectors 18.1,18.2, the front of seamed edge backstop 17 before they are arranged on distance a on sheet movement direction 27.In sheet movement direction 27 transversely, detector 18.1,18.2 is arranged in the track 28.1,28.2, and these tracks are respectively on the next door of the paper edge 29.1,29.2 of side.Track width can adapt to paper width.Detector 18.1,18.2 independently of each other the paper 4 that moves in the above of continuous detecting on sheet movement direction 27 and the speed transversely of this direction.Have two load-transfer devices 6.1,6.2 in sheet feeder platform 5, they are parallel in the zone that sheet movement direction 27 is arranged on paper edge 29.1,29.2 and can be driven by electrical motor 14.1,14.2 independently of each other.Arm-tie 30 works perpendicular to sheet movement direction 27 and is used for the paper 4.1 that leans on preceding seamed edge backstop 17 is carried to lateral edges backstop 31.
Explain the enforcement of this method below by means of the diagram of curves among Fig. 3-5.Diagram of curves among Fig. 3 illustrates the stroke of paper on sheet movement direction 27 curve relevant with the machine angle [alpha].The machine angle [alpha] is drawn by the signal of corner transmitter 25.In the angular range of 360 degree, just in time a paper 4 is flowed to sheet-fed press.Horizon is positioned on the height of line 32, and this line constitutes by preceding seamed edge backstop 17.Diagram of curves in the Figure 4 and 5 illustrate paper 4 on sheet movement direction 27 with the transversely relevant velocity curve 33,34 of this direction with the machine angle [alpha].
Diagram of curves among Fig. 3 illustrates two strokes- angle curve 35,36 of two paper of successively carrying 4.2,4.1.Corresponding to curve 35, paper 4.1 by the load-transfer device 6.1,6.2 that is synchronized with the movement with identical speed v 2 forward seamed edge backstop 17 carry, and flow to the grippers 21 of conveying cylinder 22 with speed v 1 by oscillating type paper-transferring tooth system 20 at the paper 4.2 of preceding advancing.To be provided with line 32 partition distance a ground, they at first write down the speed v 1 of the paper 4.2 that leaves from preceding seamed edge backstop 17 to detector 18.1,18.2 along line 37.If the preceding seamed edge of paper 4.1 is by straight line 37 when machine angle [alpha] 1, detector 18.1,18.2 paper speed v2 then are before paper 4.1 moves to this speed on the seamed edge backstop 17.In the velocity jump from v1 to v2 shown in the velocity curve 33.When machine angle [alpha] 2, paper 4.1 leans on preceding seamed edge backstop 17, and speed jumps to zero from v2 thus.
If paper 4.1 obliquely or reverse on sheet feeder platform 5 forward seamed edge backstop 17 carry, then on detector 18.1,18.2 in different machine angle [alpha] 1, occur during α 2 from v1 to v2 and from the transition of v2 to zero, these signal edge shown in broken lines in Fig. 4 38,39 expressions.The appearance at the signal edge 38,39 of detector 18.1 and signal edge 40,41 are compared and are postponed a differential seat angle Δ α.Can calculate the obliquity of paper 4.1 on the sheet feeder platform by the spacing of differential seat angle Δ α and track 28.1,28.2.In the machine angular range between 2 to values of α α 3, velocity curve 33 is owing to seamed edge backstop 17 resiliences of 4.1 the past of paper have negative curve.
When machine angle [alpha] 3, paper 4.1 leans still on preceding seamed edge backstop 17, begins up to machine angle [alpha] 6 from this angle, and arm-tie 30 is operated, so that paper 4.1 is with to lateral edges backstop 31.By arm-tie 30, paper 4.1 is accelerated to layback speed v Z and is drawn to lateral edges backstop 31 with identical speed v Z.In machine angle [alpha] 4, paper edge 29.2 arrives lateral edges backstop 31.Detector 18.1,18.2 records the speed zero transverse to the sheet movement direction when machine angle [alpha] 4, and this is more by finding out in the velocity curve 34.On lateral edges backstop 31, resilience occurs in the machine angular range between α 4 to α 5, make velocity curve 34 in negative region, extend.On sheet movement direction 27, produce a velocity curve in negative region again in the machine angular range between α 3 to α 4.The motion of seamed edge backstop 17 appears at when lateral edges backstop 31 is drawn before this leaving of paper 4.1, and wherein, paper 4.1 is seamed edge backstop 17 before a side that deviates from routine seamed edge backstop 31 is rotated away from slightly.
The signal of detector 18.1,18.2 is evaluation in control setup 26.Can monitor sheet movement on the sheet feeder platform 5 fully by analysis speed curve 33,34.Detector signal is directly used in the adjusting of the power element in the sheet feeder of sheet-fed press.
Arrive in order to regulate paper, determine the actual value v2 of paper speed in the machine angular range between α 1 to α 2
IstAnd with given value v2
SollRelatively.When between actual value and given value, deviation being arranged, by 6.1,6.2 the speed that controller 15.1,15.2 is regulated load-transfer devices like this, make paper 4.1 arrive with given low velocity before seamed edge backstop 17.At this, the speed of load-transfer device 6.1,6.2 also can differently change.If in detector 18.1,18.2 the above occur in different machine angles from v1 to v2 or from the velocity jump of v to zero, then load-transfer device 6.1,6.2 moves like this with different speed, make paper 4.2 have angular error ground to arrive before seamed edge backstop 17.If do not take place from v1 to v2 or from the velocity jump of v2 to zero, then produce wrong paper signal or tear the paper signal in control setup 26, this signal is used to activate retaining pawl 24 and makes sheet feeder or sheet-fed press stops.Can prevent that by retaining pawl 24 paper 4 that will tear from flowing to machine.
For such feedway: wherein paper 4 does not have and is transferred mechanism such as paper-transferring tooth system with stopping receives from the sheet feeder platform under certain speed, can regulate paper speed like this, makes that seamed edge is received in the motion identical with conveying mechanism before the paper.
Device with detector 18.1,18.2 makes it possible to be identified in the interference when seamed edge backstop 17 is carried forward.Monitor the velocity curve 33 in the machine angular range between α 1 to α 2 for this reason.If seamed edge backstop 17 was not carried before paper was crossed with not stopping, then velocity jump does not appear to zero in machine angle [alpha] 2.Relate in this case and overflow paper, wherein, in control setup 26, produce the signal that causes machine down.
The actual arrival angle [alpha] 2 of the preceding seamed edge of the signal edge 41 reflection paper 4.1 in the velocity curve 39 on the preceding seamed edge backstop 17.This paper arrives angle [alpha] 2 and can regulate or control by control paper speed.
In the machine angle between A2 to α 3, paper arrive before in velocity curve 33 after on the seamed edge backstop 17 and the machine angle between α 3 to α 4, the velocity curve 34 after paper arrives lateral edges backstop 31 comprises the information of the spring of paper on backstop 17,31.Because the paper spring diminishes printing quality, so control or adjusting are to the feeding of backstop 17,31.Can regulate the speed of load-transfer device 6.1,6.2,30 and/or regulate negative pressure based on the paper spring in order to control or to regulate by cooresponding negative pressure source 8.For example can improve feeding always, lean still on preceding seamed edge backstop 17 at interval at time enough before transversely the drawing of sheet movement direction 27 in beginning up to paper 4.1.Reduce the feeding of paper 4.1 in addition always, after paper 4.1 arrives on the backstop 17,31, begin spring.If sheet feeder is regulated and do not produced desired result, then can warn the operator of printer: deterioration in print quality.The operator then can introduce additional manual measure targetedly, is used to guarantee printing quality.
Draw the arrival angle [alpha] 4 of paper 4.1 on lateral edges backstop 31 by velocity curve 34.Regulate drawing stroke or arriving angle [alpha] 4 by means of velocity curve 34 transverse to sheet movement direction 27.By the position that velocity curve 34 can calculate paper edge 29.2, wherein, pile 2 such shifted laterallys make to produce desired arrival angle [alpha] 4.In the birds-eye view of Fig. 6, be shown specifically shifted laterally 42.For shifted laterally, be provided with electrical motor 43 and driving device 44.Electrical motor 43 is connected with control setup 26.In order to compensate the paper obliquity, suction nozzle 3 can be around vertical axis swing.In addition, can control negative pressure or the pulling force on moving direction 42 in the suction chamber below the arm-tie 30 by velocity curve 34.Reduce this pulling force so for a long time, up to guaranteeing: paper 4.1 arrives on the lateral edges backstops 31 in desired machine angle [alpha] 4 for this reason, and perhaps this degree ground improves pulling force, makes wrinkling on paper spring or the paper seamed edge 29.2 do not taken place.If this adjusting does not take place, alert operator then is so that can take the manual measure that adds.
The layout of detector 18.1,18.2 also is used to guarantee circumferential register and side direction alignment.Monitor the speed of paper 4.1 in the machine angular range between the machine angle [alpha] 7 when the α 6 when the layback motion finishes and the transfer movement of grippers 20 begin.By can before the beginning printing process, just carrying out alignment control to version by controlling continuous paper on the sheet movement direction 27 and transverse to the information of the motion on this direction about paper.In a circumferential direction or on the sheet movement direction 27, this information is used to the feeding of control by load-transfer device 6.1,6.2.The operator obtains the information about the continuous paper alignment quality of expectation.If the motion of paper 4.1 takes place in the machine angular range between α 6 and α 7, this motion can not be returned before receiving by paper-transferring tooth system 20, then alert operator printing quality defective.
Given paper 4 given speeds can be compared with the actual speed of cooresponding feed mechanism in the machine angular range of determining.Can calculate the value of the slip between load-transfer device 6 or arm-tie 30 and the paper 4 thus.As shown in Figure 1, in order to measure the actual speed of load-transfer device 6, belt speed sensor 16 is set.This slip can be regulated.Can monitor the wearing and tearing of load-transfer device 6 or arm-tie 30 equally.By can regulate for the measurement parameter that slides be used for paper 4.2 in the past seamed edge backstop 17 be transported to the speed of conveying mechanism of the grippers 21 of conveying cylinder 22, paper 4.2 is received in same movement under the speed of determining.Signal by belt speed sensor 16 can also be determined whether occurring slip between paper 4 and the load-transfer device 6 or between load-transfer device 6 and slewing rollers 13.
If paper 4 is driven forwards on preceding seamed edge backstop 17 like this, so that it is in the moment distortion of being grasped by paper-transferring tooth system 20, can cause paper 4 lax when then carrying in sheet-fed press, therefore occurs double exposure between printing mechanism.As shown in Fig. 6, can use the detector 18.1-18.3 to be used to monitor sheet movement more than two.Location information by comparing motion information and detector 18.1-18.3 can detect the paper distortion.If paper 4 distortions, then motor message is not interrelated with the position of detector 18.1-18.3.In order to resist the paper distortion, change the centripetal force of paper 4 or regulate the position of preceding seamed edge backstop 17 so that paper 4 is stable on the sheet movement direction by control negative pressure source 8.
