Definitions
- the invention relates to a method and a device for drawing in a printing material web in roll rotary printing according to the preambles of claims 1 and 10.
- Printing material webs are usually drawn into printing units of the machine by means of endless revolving tension belts which are guided over rollers within the side walls of a web-fed rotary printing press.
- Such feed systems are now largely automated through appropriate programming. In this process, feed queues are guided in via tracks and switches.
- An automated pulling device for the turning bar area is known from DE 41 30 678 Al.
- an endlessly running-in feeding tape in the form of a hook tape is guided on the feeding path, the hook of which is provided in a printing material web to be drawn in at the beginning of the web.
- Hook the loop band.
- This device requires the attachment of a loop or hook tape at the beginning of the web of the printing material web, a separate roller system for the endless guidance of the drawing tape designed as a hook or loop tape, and such an additional drawing tape.
- the pull-in device is complex and takes up a lot of space. There is also the risk of tearing when taking over the start of the web and also during transport through the feed belt.
- the invention has set itself the task of creating a safe, automated web deflection, which also ensures a clean web feed.
- a printing material web is conveyed to a deflection axis and deflected about this deflection axis when it is conveyed further, ie deflected from its conveying direction.
- the printing material web runs around a cylindrical deflection means, in particular a turning bar or a roller, the longitudinal axis of which forms the deflection axis.
- the web is pressed in the direction of the deflection axis when deflected with compressed gas, in particular compressed air. It is particularly advantageous that a web start, if it is a printing material web to be drawn in, does not have to be connected to a traction means, as is the case with known drawing systems.
- Nozzles for blowing out the compressed gas are preferably arranged along the deflection axis and distributed over an angular range around the deflection axis.
- Such a nozzle arrangement is advantageously formed by a surface which is correspondingly provided with blowing openings, in particular perforated, and which surrounds part of the circumference of the deflecting means.
- the compressed gas is preferably blown out with an overpressure against ambient pressure of a few mbar.
- the perforated surface advantageously also serves as a deflecting surface for the beginning of the web of the printing material web. The blowing of the web, especially the blowing of the beginning of the web, ensures a trouble-free deflection even in the event of contamination by paint splashes and onward transport.
- the deflecting surface is shaped in such a way that there is an annular segment-shaped space between the deflecting means and the surrounding deflecting surface, through which the printing material web is conveyed.
- a web entry into a deflection gap formed in this way is preferably widened.
- Slit nozzles can preferably also be arranged in this.
- the printing material web is pushed in the area of the deflecting means lying on a support for deflecting and is not pulled as in the prior art.
- a web support is particularly advantageously designed as a bar grate.
- the bar construction reduces the friction between the substrate and the rust and the contamination to a minimum while at the same time achieving an optimal view.
- the printing material web is preferably stiffened before the first deflection in order to improve its stability for further transport.
- a blowing device which is arranged in the case of a deflection means, is preferably easy to assemble, in particular can be repositioned, in order to be able to be used in many ways.
- a system of a few form types of web supports is proposed, with which different deflecting configurations formed from a plurality of deflecting means arranged one behind the other can be equipped with web supports.
- the attachment points of the blowing device and the web supports arranged symmetrically to a system center of the printing material web to be drawn in.
- the blowing device according to the invention and the web supports according to the invention can also be easily retrofitted to existing printing machines.
- Known deflection means in particular turning bars, are already supplied with compressed gas, which is blown out against the circumferential printing material web on the circumference, thereby reducing the friction.
- the invention can thus advantageously fall back on an existing compressed gas supply.
- Pressurized gas is supplied to the deflecting means through fastening pins of the blowing device, which are suitably attached to a deflecting means and secured with a screw plug. Since the blowing of the printing material web according to the invention is particularly advantageous when the web is being drawn in, the compressed gas supply to the blowing device can be switched off after the web start has been drawn in. Preferably, only the blowing device is applied for drawing in and only compressed air is applied to the deflecting means after the drawing in has taken place. The switching can be done manually or automatically via a switching valve, which is preferably attached in the blowing device according to the invention or in its vicinity.
- blowing devices can be arranged in the printing machine along the web feed path, so that they serve in connection with the blowing air as non-contact web tension means of the printing material web.
- the supply of blown air to the printing material web also serves to guide the printing material web true to the web.
- folding rollers are arranged in front of the respective deflecting means.
- the folding rollers at the same time form transport rollers, namely thrust drive rollers, in that they press the printing material web against a bar of the web support designed as a bar grating pointing in the conveying direction of the web and, on the other hand, protrude at least on one side, preferably on both sides, next to this bar a little bit into the support surface for the printing material web .
- the deflection means is a traction drive, preferably another transport roller, also referred to as a pulling roller because of its function.
- the full web following the start of the web is continuously transported on by these driven transport rollers.
- the traction drive also serves to guide the web in the correct direction.
- the cylindrical pulling rollers are driven with a certain advance compared to the folding rollers, which preferably does not make up more than about 20%. They press the printing material web against a bar of the web support and in this way provide a tensioning of the web via its frictional force.
- a partial web of the previously longitudinally cut printing material web is torn off over a cutting edge arranged transversely to the conveying direction of the printing material web.
- the free-hanging web beginning after tearing off of the partial web now forming the printing material web is blown with compressed air according to the invention and thus raised for further transport for drawing in.
- a second blowing device with a cutting edge is particularly advantageously provided directly in front of the thrust drive rollers between the pulling roller walls of a longitudinal cutting device. The blowing gas of this blowing device leads the beginning of the path of the partial web to the thrust drives in the manner described.
- the tearing off according to the invention with subsequent blowing and lifting of the partial web can also be used in conjunction with other drawing-in devices and in principle also anywhere where a "free" web start has to be raised for further conveying.
- the second blowing device according to the invention is to be arranged accordingly below a deflecting means, so that the hanging beginning of the web can be blown on.
- the invention is preferably used for deflecting the printing material web in the turning area of a rotary printing press, it is not only restricted to this purpose. In principle, it can be used for deflecting wherever space permits and where a blowing device can be suitably arranged for a deflecting means.
- Figure 1 shows a turning and sweeping area of a rotary printing machine in side view.
- a printing material web 1 which comes from a printing unit, is drawn over a pull roller 10 and cut lengthwise into partial webs 1 and 2 by means of a slitter 11.
- the partial web 2 is simply conveyed on in a known manner.
- the other partial web 1 becomes the pull roller 10 swept, then turned and swept via a turning bar 12, then swept again via a transverse guide roller 13, turned and turned again via a second turning bar 14, which is oriented at a right angle to the first turning bar 12, fed to a linear register roller 15 around this roller 15 swept and finally conveyed under the continuous web 2 and fed to a folder.
- Turning and sweeping configurations of the type shown in FIGS. 1 and 2 are known insofar as this relates to the arrangement of the turning bars, guide and register rollers.
- FIG. 3 shows the interface, namely the preparation and transfer of the longitudinally cut partial web 1 to a push roller, in the exemplary embodiment a folding and transport roller 50 which feeds the partial web 1 to a deflection.
- the partial web 1 to be drawn in is initially still carried along by the partial web 2 which is simply conveyed onward.
- the partial web 1 to be drawn in which due to its own weight runs approximately vertically downward from the pulling roller 10, is torn off along a cutting edge 24 arranged below the pulling roller 10.
- the tearing can be done by hand or using a suitable device. By tearing off, a defined web start 3 running transverse to the conveying direction of the partial web 1 is obtained.
- the cutting edge 24 is fastened to a blower device 20, in the exemplary embodiment a blower tube 20, which is designed essentially simply as a square tube.
- a compressed gas preferably compressed air
- the blow pipe 20 is provided with blowing openings 22 along its side facing the partial web 1.
- this web beginning swivels about the pulling roller 10 in the direction of this pulling roller 10 into the position also shown in FIG. 3.
- By blowing the web start 3 of the partial web 1 is raised onto a web support 30 and fed to a conveying means, in the exemplary embodiment a drive roller 50.
- the web support 30 is provided at its end facing the blowpipe 20 with a baffle plate 31 which is directed obliquely downward in the direction of the cutting edge 24 and which forms a kind of inlet funnel for the web start 3 with the pull roller 10.
- the blowing openings 22 blow into this inlet funnel and align lane 1 at the same time.
- the web start 3 is then conveyed or pushed on the web support 30 by pressing the drive roller 50 against the web support 30 for deflection.
- a plurality of such drive rollers 50 are arranged distributed over the width of the partial web 1 - hereinafter again referred to as the printing substrate web 1.
- FIG. 1 A deflection of the printing material web 1 according to the invention is shown in FIG.
- the beginning of the web 3 is pushed onto the web support 30 by the drive rollers 50 to the turning bar 12 and deflected by 180 ° during further pushing about the longitudinal axis 12 'of the turning bar 12.
- the turning bar 12 is surrounded along its side facing away from the web inlet and the web outlet by a deflection plate 41 of a blowing device 40 arranged concentrically to the longitudinal axis 12 'of the turning bar 12.
- the surface of the turning bar 12 forms, with the deflecting surface 41 ′ of the deflecting plate 41 facing it, a semi-ring-shaped deflecting gap around the turning bar 12. On the inlet side, this deflecting gap formed in this way is widened by correspondingly guiding the deflecting plate 41.
- the deflection plate 41 is provided with blow holes 42, through which compressed gas can be blown in the direction of the turning bar 12 or its deflection axis 12 '.
- the baffle plate 41 itself forms the end face 41 'of the turning bar 12 of a box 45 which extends along the turning bar 12 and to which compressed gas can be supplied via a feed line 48 and a changeover valve.
- the beginning of the web 3 entering the deflection is deflected in the desired direction by this end surface 41 ', which forms a deflection surface 41', the inflowing pressurized gas assisting the entry and the passage.
- the compressed gas flowing in from blowing nozzles 43 provides a certain pushing force in the conveying direction when the web runs in, and that from the blowing holes 42 creates an air cushion by means of which the friction between the printing material web 1 and the deflection surface 41 'is substantially reduced.
- the compressed gas flowing out through blowholes 44 at the outlet lifts the printing material web somewhat to reduce the friction at an outlet edge 100 of Deflection surface 41 'and in the initial region of the grating 30.
- the blowing device 40 shown in FIG. 4 is used in the embodiment described with parallel turning bars or with the inlet at the top.
- the turning bar 12 lies, as shown in FIG. 4a, over the inlet of the printing material web, so that it is drawn in from below.
- the blowing device 40a is provided with the deflecting surface 41a '.
- the deflecting surface 41a 'or the deflecting plate 41a differ essentially, apart from design differences, in that it only has blow holes 42.
- blowing device 40b according to FIG. 4b for the transverse guide roller and the blowing device 40c according to FIG. 4c for the linear register are only provided with blowing nozzles 43 at the web entry, which is usually sufficient for larger deflection radii.
- the blowing device 40 is shown in plan view.
- the fastening pin 48 of the blowing device 40 is plugged onto the turning bar 12 and secured with a screw plug.
- Compressed gas can be supplied to both the blowing device 40 and the turning bar 12 via a common feed 49.
- the feeder 49 branches into a feeder 46 to the box 45 of the blowing device 40 and a feeder 47 for the turning bar 12.
- the branching takes place by means of a changeover valve which is attached directly to the deflection plate 41.
- turning bars 12 are provided on the circumference with blowing openings in order to reduce the friction of the printing material web when turning.
- the blowing device 40 according to the invention can thus be connected to the compressed gas system already provided for the turning bars 12, as a result of which the design effort can be kept low.
- compressed gas is first supplied via the changeover valve to the blowing device 40, while the supply 47 to the turning bar 12 is initially closed.
- the feed 45 to the blowing device 40 is closed by the changeover valve and the feed 47 to Turning rod 12 opened to act on the turning rod 12 with compressed gas in a known manner.
- the blowing device 40, 40a, 40b or 40c is supplied with compressed gas at a pressure of 25 to 180 mbar.
- the compressed gas is blown out with an overpressure of approximately 0.1 to 6 mbar.
- FIG. 5 Also shown in FIG. 5 is an incoming web start 3 with the embossed stiffening grooves 5.
- the turning bar 12 is arranged at an angle of 45 ° to the web start edge. It can be seen how the beginning of the web 3 runs into the deflection gap with its right tip 6 in FIG. 5.
- FIG. 6 shows the development of the deflecting surface 41 'of the deflecting plate 41.
- the deflecting plate 41 is divided into two partial areas 42.1 and 42.2, each of which is provided with simple blowing holes 42, 44 and blowing nozzles 43.
- the baffle plate 41 has a simple, elongated rectangular shape, which is bent in the form of a segment of a circle that spans an angle of somewhat more than 180 ° including the inlet and outlet area to the baffle surface 41 '.
- the two perforated sections 42.1 and 42.2 are arranged in the longitudinal direction of the baffle 41 next to each other symmetrically to the right and left of a central transverse axis of the baffle 41.
- a left and a right outer side zone of the deflection plate 41 remain free of blow openings.
- the tip 6 (FIG. 5) of the beginning of the web 3 entering the deflection gap is conveyed during the deflection in the region of one of these two perforation-free side zones, so that the tip 6 does not run into a blow hole 42 and may possibly cause a web jam in the deflection gap.
- Two rectangular cutouts in the baffle 41 together with the box 45 form the blowing nozzles 43.
- FIGS. 7 and 8 show the conveying means 50 according to the invention for conveying the web start 3 to be drawn in.
- the conveying means is designed as a drive roller 50 which presses a printing material web resting on a web support 30 against the support 30 and conveys the web as it rotates in the direction of the turning bar 12 from FIG. The beginning of the path 3 becomes the turning bar 12 by the drive roller 50 pushed there.
- Several such drive rollers 50 are individually driven by electric motors 70 which are fed with variable direct current.
- the web supports 30 are formed by bar gratings with tubular bars 32 pointing in the conveying direction.
- the drive rollers 50 are each arranged opposite a tubular rod 32 and can be pressed against the tubular rod 32, so that a web start 3 resting on the tubular grate 30 is pushed forward by the driven drive roller 50.
- the freely lying printing material web is provided with stiffening grooves 5 (FIG. 7).
- the drive roller 50 has a circumferential depression 54 on the circumference, which is enclosed between projections 52 circumferentially circumferentially on both sides. With the two projections 52, the drive roller 50 protrudes into the support surface of the bar grate 32 on both sides of the opposite tube rod 32 if the drive roller 50 with its recess 54 is pressed against this tube rod 32. As a result, the beginning of the path 3 is pressed into the spaces between the two adjacent tubular rods 32 during conveying and is provided with the stiffening grooves 5. Because of their dual function, the transport roller 50 is referred to below as a folding drive roller.
- FIG. 8 shows an example of a piston / spring mechanism with which the folding drive roller 50 can be pressed onto the bar grate 30 and moved away from it again.
- the folding drive roller 50 is rotatably mounted on a swivel arm 59 about an axis 55 pointing transversely to the conveying direction of the printing material web. Between the pivot axis 55 and a receptacle of the folding drive roller 50 in the pivot arm 59, a piston rod 56 is pivotally pivoted to the pivot arm 59.
- the swivel arm 59 can be pivoted by a piston 57 against the pressure of a spring 58 and the folding drive roller 50 can be pressed against the opposite tubular rod 32 of the bar grate 30.
- This pressing takes place immediately after the beginning of the web 3, as described in connection with FIG. 3, has been fed between the bar grate 30 and the folding drive roller 50.
- the web start 3 and the trailing web are then provided with stiffening grooves 5 and deflected around the turning bar 12.
- the downstream transport device (FIGS. 17 and 18) is formed by cylindrical pulling rollers 50 ′ which press the beginning of the web against the tubular rods of the grate 30 arranged behind the turning bar 12 and pull it around the turning bar 12.
- These traction rollers are driven with a lead at about 25% compared to the upstream stage or the folding drive rollers 50.
- the printing material web 1 can advantageously be kept taut and a lateral course and a possible congestion of the printing material web can be avoided.
- the folding drive rollers 50 are also driven with a certain advance relative to the incoming printing material web 1.
- the drives of the folding drive rollers 50 (FIGS. 7 and 8) and the pull rollers 50 '(FIGS. 17 and 18) are electric motors.
- the activation, i.e. the delivery of the folding and drive rollers 50 is carried out pneumatically in the manner described by the piston 57. Rollers that are not in engagement simply run along empty.
- the infeed of the groups of folding drive rollers 50 and pull rollers in the turning and sweeping area is controlled by a corresponding control in accordance with a preset control matrix.
- the drive motors can be controlled at the same time and the control effort can thus be kept low.
- the transport rollers 50 ' which rest on the web due to their own weight, are lifted pneumatically by pistons 75.
- FIGS. 9 to 13 the deflection means 10, 12 to 16 and these deflection means upstream and downstream of the bar gratings 30 of the turning and sweeping configuration shown in FIGS. 1 and 2 are shown schematically in the order in which the printing material web passes through.
- the first turning bar 12, the transverse guide roller 13, the second turning bar 14 and the linear register roller 15 are each provided according to the invention with blowing devices 40, 40a, 40b, 40c.
- the beginning of the web of the printing material web is conveyed so as to rest on the bar grating 30 arranged in front of the deflecting means.
- As few, standardized basic shapes as possible, as described below, are used as bar gratings 30.
- the bar gratings 30 are at a distance of at least 5 mm from the theoretical web position, so that there is no contact between the printing material web during operation and the bar grating takes place.
- the bar gratings before and after the linear register roller 15 are firmly screwed, since they remain the same in all turning and sweeping configurations used in practical operation.
- the remaining bar gratings 30 are arranged symmetrically to a system center of the printing material web conveyed by the turning and sweeping configuration and can be adapted by repositioning any turning and sweeping configuration used in practice. The same applies to the blowing devices 40 and 40a.
- FIG. 14 shows in table form the four basic elements A, B, C and D of bar gratings 30, which can be adapted to the different arrangements of turning bars by simply repositioning them.
- the number of the respective basic elements A to D for each of the four possible arrangements of turning bars 12, 14 with or without a transverse guide roller 13 is entered in the table.
- FIGS. 15 and 16 show, in cross section and in plan view, an example of a bar grate 30 of type A.
- the tube bars 32 are fastened in a frame 34.
- the frame 34 has the shape of a right-angled, isosceles triangle, which has been cut off at one of its two 45 ° edges at right angles to one of the two perpendicular legs.
- a plurality of tubular bars 32 are arranged closer to one another than in the two areas in between, so that the beginning of the web does not thread under the bar.
