Abstract
In a device for positioning a sheet front edge at the stopping part in a sheet-processing machine, a compression roller acting on the sheet is arranged, the compression roller can be linearly arranged along and against the sheet conveying direction in order to change the feeding force acting on the sheet.
Description
Technical field
The present invention relates to the device at the backstop place in a kind of machine, such as printer or mould cutting machine for page leading edge being positioned at processing page
Background technology
In the continuous glassware of the machine of processing page, page individually or with flakey is transported to continuation processing station.Before page being transferred to continuation processing station, described page is alignd along page throughput direction at leading edge backstop place.The conveying of load-transfer device realization at described leading edge backstop place of the withdrawing air of continuous circulation such as can be applied by means of at least one.
Such as be well known that by DE 19525549 C2, be provided with a kind of pinch rollers, described pinch rollers is arranged in be had in the region of flakey spacing relative to leading edge backstop and to act on page to be aligned from top, to improve page and the contact being arranged in the feed roller below described page, because this ensure that, page is sent to well until leading edge backstop place.
A usual problem is, the page utilizing enough feeding force to be transported to leading edge backstop place is hit in described leading edge backstop with too high energy.At this, the described page of one side may be rebounded or page leading edge deforms due to backstop and damages thus.Therefore, this particularly may result through grabbing device and catches during page leading edge and go wrong in continuation conveying.
Summary of the invention
The object of the invention is to, propose a kind of device, described device can the feeding force of regulating action in page.
According to the present invention, this object is realized by feature according to claim 1.
Special advantage of the present invention is, arranges a pinch rollers acted in the region of page leading edge in page to be aligned, described pinch rollers can along or be conditioned against page throughput direction.The thrust of described roller in page and the thrust on feedway can be regulated by described measure, therefore can regulate the feeding force be applied in page.
In order to make described plant automation, arrange the linear system that an energy motor drives, described linear system is connected with sensor, and described sensor is arranged in the region of the continuous stockline formed by leading edge backstop.
In favourable layout, before sensor is not only arranged in continuous stockline but also after being arranged in described continuous stockline, thus particularly also can detects the part exceeding continuous stockline of described page and the gauffer of page can be detected.
Accompanying drawing explanation
Embodiments of the invention are shown in the drawings and be described as follows.In accompanying drawing
Fig. 1 illustrates rotary sheet-fed printing presses with section drawing in sketch,
Fig. 2 illustrates the birds-eye view on the continuous material region in the region of leading edge backstop,
Fig. 3 illustrates the section drawing of the leading edge backstop of dissecting in front and continued material region,
Fig. 4 illustrates an embodiment of the sensor by having the below being arranged in delivery system.
Detailed description of the invention
Process the machine of page 7, such as mould cutting machine or printer 1 there is continuous glassware 2 and there is when printer at least one printing device 3 or 4 and collector 6.Page 7 stacks 8 from page and to be removed and separated or be scaly transported to printing device 3 or 4 by transport platform 9.In known manner, described printing device comprises a plate cylinder 11,12 respectively.Plate cylinder 11 and 12 has a device for the forme of fixing flexible respectively.In addition, one is configured for semi-automatically or fully automatically changing the device of forme to each plate cylinder 11,12.
Page stacks 8 and is placed on the master that can control to lift and stacks on plate 10.From page stack 8 above realize taking out page 7 by means of so-called dust collecter 18, in addition, described dust collecter has the lifting aspirator for separating of page 7 and the traction aspirator of some.In addition, arrange blowing device for making the page layer of the top of control member loose, described control member is used for tracking and stacks.Stack 8 to make page, page 7 that particularly page stacks the top of 8 aligns, arrange the side of some and backstop below.
Preferably by means of the load-transfer device 21 that can apply withdrawing air, the page be separated by dust collecter 18 is transported in leading edge backstop 22 by means of at least one load-transfer device 21.Leading edge backstop 22 is spaced transverse to page throughput direction layout of turning up the soil abreast.
Above page stream, with the spacing a (scale lengths of a=page) relative to leading edge backstop 22, pinch rollers 23 is set at interval, described pinch rollers acts in page 7 in the region of trailing edge, described page to be pressed to the load-transfer device 21 that transport platform 9 guides or the follow-up page pressed between described page and described load-transfer device.Decrease sliding between page 7 and feedway by described measure establishes and feedway is good contact.
The page 7 being transported to leading edge backstop 22 place circumferentially or page throughput direction align at described leading edge backstop place.Pinch rollers 23 is preferably configured to brush roller and can be rotatably supported in fork-shaped bearing 20.Fork-shaped bearing 20 has the linear transmission 25 of band servomotor 27, and described servomotor is for changing pinch rollers 23 position.
On the one hand, the quality of page and hardness change when processing the page of different size and thickness.Therefore possible that, page is carried with the mass impact too high towards leading edge backstop 22.At this, page leading edge is out of shape and may be exceeded the continuous stockline A determined by leading edge backstop 22.The gauffer of page is caused at this.
Sensor 24 in one or more region being arranged in continuous stockline A detects the page that exceeds continuous stockline A and produces the control signal for servomotor 27 by means of computer for controlling 26, and described servomotor controls the position of pinch rollers 23.
As in the case of the embodiment according to fig. 2, sensor 24 is configured to opto-electronic pickup and is integrated in transport platform 9.Opto-electronic pickup extends on length b along page throughput direction, before described length originates in continuous stockline A and after ending at continuous stockline A.
Arranging according in the embodiment of Fig. 3, sensor 24 is being crossed the top that continuous stockline A is arranged in transport platform 9, wherein, observing along page throughput direction, before surveyed area originates in continuous stockline A and until continuous stockline A.
According to the simple sensor 24 arranged in the embodiment of Fig. 4 with diode or photoelectric switch form, observe, after described sensor is only arranged in continuous stockline A along page throughput direction.
If carry page 7 with the speed too high towards leading edge backstop 22, so produce too high mass impact when page leading edge is touched in leading edge backstop 22.Described process causes page leading edge to be out of shape, thus the part of page leading edge exceeds continuous stockline A.Can the described part of page leading edge be detected by means of sensor 24 and can continue to be transferred on servomotor 27 by means of correspondingly conditioning signal.Servomotor 27 makes pinch rollers 23 against page throughput direction away from leading edge backstop 22 shift position by means of linear transmission 25.Stoped by described measure or cancel the contact of pinch rollers 23 and page 7 and the carrying capacity acted in page is minimized.Therefore, page can slide relative to its feedway, such as load-transfer device 21 or the page of being carried by load-transfer device 21 be positioned at below described page and carry towards leading edge backstop 22 with less power.
In addition propose, reduce the swabbing pressure of load-transfer device 21, to reduce to act on from down the power of page and to realize page and slide relative to load-transfer device 21 equally simultaneously.
