Definitions

  • the invention relates to a method and a device for aligning sheets that are fed to a sheet processing machine via a sheet feeder, according to a patent (patent application P 33 05 606.4).
  • a sheet feed and feed device in printing machines with feed table front and side marks and rotating pre-gripper are known, in which the front marks come in from below into the feed table plane and allow sheet alignment or pre-alignment in a covered state.
  • a side pulling device also works in a covered state.
  • a suction pull bar detects the aligned sheet and transports it transversely to the sheet conveying direction out of the area of the side pulling device into a desired position, in which the pre-gripper detects the sheet leading edge and transports the sheet provided in this way.
  • the next sheet of the scale is fed so that in turn the leading edge and side edge alignment can be carried out.
  • the object of the invention is to align each other slightly laterally staggered sheets transported over the feed table without the aid of fixed stops.
  • the sheet aligned at its front edge is detected by a side alignment device on its underside, that the side alignment device is controlled in such a way that the detected sheet is transported transversely to the sheet conveying direction into the precise, lateral position and that Side alignment device holds the sheet in this target position until sheet-promoting means take over the sheet with a precise fit.
  • the method according to the invention can be implemented, for example, by a device in which a suction pull bar is provided in the alignment area of the sheet feeder, which can be pushed back and forth across the sheet conveying direction by means of a drive in the sheet plane and which is connected to a pressure generator with the interposition of an air control, whereby the drive of the squeegee can be controlled by a positioning device, and the squeegee firmly sucks the underside of the sheet entering the alignment area, which is already aligned at its front edge, transported to a precisely fitting lateral position and released exactly in this desired position by the action of fresh air, as soon as sheet-promoting agents have grasped the sheet.
  • the suction strip according to the device according to the invention transports the sheet to be aligned laterally by means of static friction.
  • the method according to the invention and the device for carrying out this method thus not only make side pulling devices with stops superfluous, but also enable a safe lateral displacement of the sheet to be aligned into the precisely fitting position.
  • the squeegee can be arranged directly in front of the front marks, whereby the scale distance can be reduced to about half of what is currently common for sheet feeders. All of these advantages contribute significantly to the fact that Sheet feed and registration speed can be increased significantly without sacrificing accuracy.
  • an electromotive actuator e.g. a DC motor with a small time constant
  • this actuator being controllable by a positioning device, for example an electro-optical scanning device.
  • a positioning device for example an electro-optical scanning device.
  • the squeegee can be extremely light and stable, e.g. Made of aluminum or a glass fiber reinforced plastic and extremely smoothly but exactly guided in the sheet feeder can be moved transversely to the sheet conveying direction.
  • the suction strip can advantageously be formed from a number of suction chambers, the outer ones of which can be switched on or off in accordance with the sheet format to be processed.
  • a particularly advantageous development of the invention consists in that one or more suction pulling strips are accommodated in an alignment cylinder connected downstream of the feed table.
  • This alignment cylinder can be arranged between the feed table and a feed cylinder, wherein, for example, 5 suction pull bars are provided in the alignment cylinder, symmetrically distributed over the circumference, and a suction pull bar is also assigned to each front mark.
  • sheets 2 are fed to a pre-gripper cylinder 3 offset in a scale-like manner.
  • Transport elements which are not shown in more detail, provide the feed of the sheets.
  • the foremost sheet 4 of the scale covers the subsequent sheet or sheets 2 and is located in the so-called alignment area 5.
  • the front edge of the foremost sheet 4 of the sheet lies against the front marks 6.
  • a suction strip 8 is provided in the alignment area 5 and extends almost over the entire width of the feed table. It is mounted in the feed table 1 transversely to the sheet conveying direction, as indicated by the double arrow 9, and can be moved back and forth.
  • the suction strip 8 consists of several to or. Switchable suction chambers 10. It is preferably made of a light material, for example aluminum or glass fiber reinforced plastic.
  • the suction strip 8 is driven by a stepper motor 11, for example a direct current motor with a small time constant. The power transmission from the stepper motor 11 to the suction strip 8 takes place via two drive cams 12 and two cam rollers 13.
  • the two drive cams 12 are on the stub shaft 14 of the stepper motor 11 attached that the sum of the distances of the opposing sections of both cam tracks from the axis of rotation of the stepping motor 11 is always the same. This enables play-free rolling of the two cam rollers 13, which are rotatably mounted on the suction pull bar 8, on the drive curves 12.
  • a query gap 15 is provided in the feed table 1 both on the drive side and on the operator side.
  • a sensor 16 is laterally adjustably mounted on a crossbar 17.
  • This sensor 16 belongs to a positioning device, not shown, for example according to patent (P 33 05 606.4). As indicated by the dot-dash circle 17, the sensor 16 can also be provided above the interrogation gap 15 on the operating side.
  • the sensor 16 and the interrogation gap 15 are located between the suction strip 8 and the front marks 6.
  • the sequence of the scanning and aligning means could be as follows, first the leading edge of the sheet passes the suction strip 8, then the scanning gap 15 and finally comes to rest on the front marks 6.
  • FIGS. 3 to 8 Another embodiment of the invention is shown in FIGS. 3 to 8. The point here is to carry out both the front and side edge alignment with a flowing sheet feed.
  • An alignment cylinder 20 is mounted in the machine side walls 21 and 22 below the lower end of the feed table 1. As FIG. 5 shows, the bearing of the shaft 23 of the alignment cylinder 20 consists of one roller bearing 24 each.
  • the alignment cylinder 20 is followed by a half-speed pre-gripper cylinder 3, which transfers the sheet taken over to the impression cylinder 50 of the first printing unit of the sheet-processing machine.
  • transport members 25 are indicated, which ensure that the sheets 2, which are conveyed in a scale-like manner and are conveyed over the feed table, are fed to the aligning cylinder 20 and there, after contact with a number of front marks 6, are gripped by a suction strip 8.
  • the alignment cylinder 20 transfers the aligned sheet 4 to a gripper bridge 27 of the pre-gripper cylinder 3.
  • the alignment cylinder 20 is provided with five suction pulling strips 8 arranged symmetrically on the circumference. Accordingly, its surface speed is approximately five times lower than that of the printing cylinder 50.
  • a suction strip 8 is arranged directly in front of each row of front marks 6.
  • the special design of the alignment cylinder 20 is shown in more detail in FIGS. 4 and 5.
  • sheet guiding segments 28 are provided, which are adjustably mounted on a cross member 29 in the axial direction of the aligning cylinder 20 such that a query gap 15 can be formed between two of them.
  • the circumferential length extension of the arc guide segments 28 is somewhat larger than the circumferential length of the alignment region 26.
  • a traverse 49 extending across the machine is fastened in the side walls 21 and 22 above the alignment cylinder 20, on which one or two sensors 16 of a positioning device (not shown) are adjustably mounted. These sensors 16 register the time at which the side edge of the sheet 4 is passed. They are set to the sheet format to be processed in each case. Corresponding to the respective position of a sensor 16, the sheet guide segments 28 provided in this area must be arranged in such a way that a query gap 15 is formed directly below the sensor 16.
  • the two gripper bridges 27 are pivotally arranged in the pre-gripper cylinder 3 in such a way that, after the sheet has been taken over from a swiveled-out position, they gradually pivot back onto the circumference of the feed cylinder 3, so that the detected sheet 4 gradually moves from the low speed of the aligning cylinder 20 to the higher peripheral speed of the pre-gripper cylinder 3 is accelerated.
  • the front mark cover grippers 30 are pivoted in the alignment cylinder 20 on a shaft 31 and another gripper shaft 32 is tiltably supported.
  • the front mark cover grippers 30 are fixedly connected to a guide roller lever 33 on which a guide roller 34 is rotatably mounted. This guide roller 34 runs along a control cam 35 rotating with the alignment cylinder 20 during the pivoting of the front mark cover grippers 30.
  • the area of the sheet guide surface of the alignment cylinder 20 from the front marks 6 to the beginning of the sheet guide segments 28 runs flat, so that the suction of the lower sheet edge by the suction strip 8 is not made unnecessarily difficult becomes. In addition, an absolutely flat contact of the leading edge of the sheet with the front marks 6 is to be achieved.
  • the sheet guiding surface can also be curved.
  • the suction strip 8 consists of a series of mutually sealed suction chambers 10. These are connected via air lines 38 to a valve body 39, in such a way that the two outer suction chamber groups by means of valves 40 depending on the sheet format to be processed can be switched off.
  • the valve body 39 is fixedly attached to the shaft 23 of the alignment cylinder 20. Via a seal 41 it works together with a valve ring 42 which is fastened to the side wall 21 of the sheet-processing machine.
  • a suction opening 44 and a fresh air opening 45 are provided in the control surface 43 of the valve ring 42 at the same radial height.
  • the control surface 46 of the valve body 39 has an air control opening 47 to which all the air lines 38 of the suction chambers 10 are connected.
  • each air control opening 47 is at the same radial height as the suction and fresh air openings.
  • the width of the air control opening 47 corresponds approximately to the distance between the suction opening 44 and the fresh air opening 45.
  • an air control opening 47 is assigned to each suction pulling strip 8.
  • the suction opening 44 is connected via an air line 48 to a vacuum generator, not shown.
  • the dimensions of the suction opening 44 of the fresh air opening 45 and the air control opening 47 are such that the negative pressure generated in the respective suction pulling strip 8 for holding the sheet 4 breaks down by supplying fresh air as soon as the gripper bridge 27 has firmly taken over the leading edge of the sheet.
  • FIG. 5 shows a section through the feeder 1 and the alignment drum 20 as seen from the sheet-processing machine
  • the drive of the suction pull bars 8 is located on the drive side of the sheet feeder. It consists first of all of a stepper motor 11 with a reduction gear, which is fastened to the side wall 22 by means not shown.
  • a stepper motor 11 with a reduction gear which is fastened to the side wall 22 by means not shown.
  • two drive cams 12 of the same design are fastened, which are diametrically opposed to one another in such a way that their two cam tracks always have the same distance in the diagonal direction to the motor.
  • a cam roller 13 runs on each of these drive curves 12. These cam rollers 13 are fastened to a drive rod 54 via a bearing block 53.
  • Drive curves 12 and cam rollers 13 work together in such a way that the rotational movement of the stub shaft 14 of the stepping motor 11 is transmitted to the drive rod 54 without play.
  • the latter is mounted axially displaceably, one in the guide console 55 and the other in the machine side wall 22. Both bearings consist of ball bushings 56.
  • the free end of the drive rod 54 on the inside of the machine side wall 22 is provided with a control segment 57, which is provided with drive rollers 58 each squeegee 8 can engage, such that the axial drive movement of the drive rod 54 is transmitted to the squeegee 8 to be driven in each case without play.
  • the control segment 57 seen in the axial direction of the drive rod 54, is slidably accommodated in a recess of a return disk 59.
  • a guide 60 also projects into this recess of the return disk 59, in which a guide roller 61 runs, which is rotatably mounted on the underside of the control segment 57. In this way, the drive rod 54 is secured against rotation.
  • Both the guide 60 and the return disk 59 are attached to the side wall 22.
  • FIGS. 6 to 8 show the essential working positions of the control segment 57.
  • the control segment 57 In the middle FIG. 7, the control segment 57 is in its middle zero position. It takes up this position before an adjustment of a suction pulling strip 8 is to be carried out.
  • the drive rollers 58 which are normally guided by the return disk 59, of a suction pull bar 8, which, as can be seen from the above, rotates with the alignment cylinder 20, have just reached the control segment 57. The adjustment process can begin at this moment.
  • the stepping motor 11 rotates the drive cams 12 via the shaft end 14 in such a way that the drive rod 54 is pulled in the direction of the drive side until finally after signaling that the sheet edge has been passed by sensor '1 an exactly predetermined remaining distance has been covered.
  • the drive rod 54 remains in this position, as shown in FIG. If the stepper motor 11 is actuated accordingly, the control segment 57 stops before reaching the maximum stroke and thus guides the adjusted suction strip 8 in this desired position until the alignment process has been completed and the aligned sheet 4 has been taken over by further funding. After this adjustment process, the return disk 59 returns the suction strip 8 to the zero position.
  • the drive rod 54 is moved into the machine interior by the stepping motor 11, and in fact up to the position shown in FIG. 8. With appropriate positioning, the control segment 57 comes to a standstill before this end position and guides the adjusted suction strip 8 in this position until the laterally aligned sheet 4 has been taken over by the feed cylinder 3. Even after this adjustment, the return suction disc 8 is returned to its zero position by means of the return disk 59.
  • the side edge alignment then begins in the so-called alignment area 26 during the further transport of the sheet 4, in such a way that the sheet is sucked in firmly after the leading edge alignment has been carried out due to the air control of the suction pull bar 8, so that between the underside of the sheet and the sheet Suction surface 62 of the suction strip 8 static friction arises.
  • the sheet 4 has thus been gripped non-slip.
  • the suction strip 8 has assumed the position in FIG. 7, that is to say that its drive rollers 58 have contact with the control segment 57 without play.
  • the control segment 57 is now moved via the stepper motor 11, the cam drive 12/13 and the drive rod 54 Direction to the end position according to FIG. 6.
  • the sheet is thus conveyed in the direction of the drive side, at some point in the alignment area 26 the operator-side sheet edge passes the sensor 16 and due to the interrogation gap 15 a reflection of the light emitted by the sensor 16 no longer takes place, whereby the Positioning device controls the stepper motor 11 in such a way that the sheet 4 then only covers a very specific distance, for example 2.00 mm.
  • the suction pull bar can be replaced by preferably two suction pulling shoes, which are also mounted in the feed table so as to be displaceable transversely to the sheet conveying direction.
  • One suction shoe is arranged on the drive side and the other on the operator side. Both suction shoes are driven by appropriate means.
  • a control device influencing the positioning device can be provided for the purpose of different positioning of the two side pull shoes.
  • a further modification of the described embodiments can consist in that the air control is arranged in the center of the alignment cylinder or on the drive side.
