The present invention relates to a kind of printing machine page spreaders, including the first roller (1), for rotating the first driver (11) of first roller, second roller (2), wherein, second roller follows first roller on page direction of transfer (BFR) to be deployed or to smooth page (B).First driver is controlled in this wise by control device (17), so that first roller alternatively rotates in terms of the transmission rhythm of page when press printing constant airspeed.

Description

The page spreader of printing machine
Technical field
The present invention relates to a kind of page spreader of printing machine, the page spreader includes the first roller, the second roller and position Medial compartment between first roller and second roller, page of second roller in (or to smooth) page to be deployed It opens and follows first roller on direction of transfer.
Background technique
Such a page spreader is described in 26 48 986B1 of DE, its two supporters rotatably support simultaneously It is driven corresponding to page speed with circumferential speed.
Another page spreader is described in 33 45 201A1 of DE, wherein by driven suction roll, so that two A support roller rested on the suction roll can be driven by friction.The support roller under the suction roll and necessary situation Driver can hold in the month to take from one or two and removed on device chain, thus, it is possible to be carried out roller circumferential speed according to page travelling speed Simply it is adapted to.
Summary of the invention
Task of the invention lies in propose another page spreader.
The task is addressed by the page spreader with feature described in claim 1.
Page spreader in printing machine according to the present invention includes: the first roller；For rotating the first of first roller Driver；Second roller, wherein second roller follows described first on page direction of transfer to be deployed or to smooth page Roller (namely being arranged in first roller downstream), is equipped with medial compartment, and described between first roller and second roller First driver is controlled in this wise by control device, so that first roller is in page in the case where press printing constant airspeed The transmission rhythm openedAspect is alternativelyRotation.
The advantage of page spreader according to the present invention is: the page spreader is especially suitable for by relative stiffness Page made by (inflexible) material.
There are a variety of feasible improvement projects for page spreader according to the present invention.
First driver can be motor.The second driver for rotating second roller can be equipped with.It is described Second driver can be motor.Second driver can be controlled in this wise by the control device, so that in printing machine Second roller alternatively rotates in terms of the transmission rhythm of page in the case that print speed printing speed is constant.The medial compartment can be by true Empty generator load is to aspirate air.Support component can be disposed in the medial compartment, the support component has towards page Supporting surface.The supporting surface can have concave curvatures upwardly extending in page sender, with radius.In described Injection tube can be disposed on compartment, page is squeezed into the medial compartment by the injection tube.First roller and described Two rollers can have slot in their periphery respectively, these slots are constituted for holding the channel for taking device in the month, these, which are held in the month, takes device by page It is kept fixed.
Detailed description of the invention
Other improvement projects are obtained from the description of next embodiment and attached drawing.Attached drawing is shown:
Fig. 1: the space view of page spreader；
Fig. 2: the side view of page spreader；
Fig. 3: the detailed view of page spreader；With
Fig. 4: page spreader according to fig. 2 in IV-IV cutting line view.
Specific embodiment
Fig. 1 shows the page spreader in the discharger of the printing machine of offset printing or ink jet printing.The page expansion Device is arranged between guide plate 3 and including the first roller 1 and the second roller 2, and first roller 1 and 2 diameter of the second roller are identical and axial In parallel.First roller 1 is rotated by the first driver 11, and second roller 2 is rotated by the second driver 12.These drivings Device 11,12 is motor and couples as direct driver with these rollers 1,2.Calibrator (-ter) unit can be equipped with It (Justageeinrichtung), can be according to the rigidity of page to be processed to change the roller 1,2 by the calibrator (-ter) unit Rotation axis between distance between axles.
Fig. 2 shows holding in the month for the chain conveyor of discharger to take device bridge 4.It is described hold in the month the leading edge that takes device bridge 4 to page B into Row is fixed and draws page B on page direction of transfer BFR by the page spreader.Here, the page B composition is curved It encloses (Schleife), the curved circle is extruded between the roller 1,2 by injection tube 6.The injection tube 6 refers to towards page B To and support the page B to takeoff onto page spreader.The curved circle is displaced (wandert) by page B from front to back, by Page B is unfolded in this.
Fig. 3 is shown, and medial compartment 9 is connected to vacuum generator 18 and constitutes negative pressure cavity, and the negative pressure cavity is by rear sealing 8 limit of part 7 and front seal.The rear seal 7 rests on first roller 1, and the front seal 8 rests on institute It states on the second roller 2.
The negative pressure cavity can be filled for example by lead screw transmission by side seal 5 (referring to Fig. 1) limit, these side seals 5 It sets mutually direction ground or adjusts away from each other.Show that the specification of page spreader sets shape according to the width of page B as a result, State F.
Support component 13 is disposed in the medial compartment 9, it is R (referring to fig. 2) that the support component 13, which has radius, Supporting surface 14.Based on the visual angle of page B, the supporting surface 14 is spill.The supporting surface 14 can coated be reduced abrasion Protective layer.The support component 13 be and the roller 1,2 in parallel lengthwise extend item (Leiste).In the support component Introducing in 13 has hole, this some holes is passed into the supporting surface 14.Suction air is flowed into the negative pressure cavity by this some holes And it is flowed into from this in vacuum generator 18.The curved circle abuts on the supporting surface 14 that radius is R, the radius R The shape of the curved circle is thereby determined that.In order to enable after page B takeoffs (Anspringen) in the page spreader Negative pressure will not be excessively increased, settable pressure limit valve.
Fig. 4 is to be illustrated with the second roller 2: these rollers 1,2 have rill (Relief), and the rill has the ring of protrusion And the slot 15 positioned at interannular.These slots 15 around roller circumference extend and on page direction of transfer BFR (referring to Fig. 1) respectively with It holds in the month and takes holding in the month for device bridge 4 that device 16 is taken to be aligned.Take device bridge 4 when these 1,2 side operations of roller are passed through in described hold in the month, described hold in the month takes device 16 It partly sinks in these slots 15.These rollers 1,2 protrude slightly above the page guide surface more than the guide plate 3 towards page B.
The present invention operates as follows: control device 17 is connect with the driver 11,12 and basis is determined by master driver Print speed printing speed to control the revolving speed of the driver 11,12.Holding in the month for chain conveyor takes device bridge 14 corresponding to printing speed The transmission rhythm of degree transmits page in succession by the page spreader, wherein each page is flattenedThis Outside, the control device 17 controls the driver 11,12 in this wise, so that the institute for each page B to be deployed It states the first roller 1 briefly to accelerate and then slow down, and second roller 2 also alternatively rotates, preferably not with first roller 1 It is synchronous.First roller 1, the circumferential speed that is improved for holding the transmission speed for taking device bridge 4 in the month only may be present in it is as follows In period: in the period, the front section of page B and the roller 1,2 is opposite.First roller 1 can hereafter subtracted Speed, so that size is identical again for circumferential speed and transmission speed when back section is opposed.
