Definitions
- the invention relates to an alignment device, in particular for a single sheet printer or copier, for aligning a single sheet of a recording medium, with a sensor device which detects the side edge of the sheet in order to determine its position relative to a desired printing position, with a transverse to the transport direction of the Sheet movable transport device, with which the sheet held by it can be aligned depending on the determined position in the target pressure position and the two oppositely arranged, in a transverse to the direction of transport line touching transport units, the line of contact has a stop for forms the front edge of the recording medium, and with a feed device feeding the sheet to the transport device, which in the transport position conveys the sheet before being gripped by the transport units to such an extent that the sheet moves between the feed device and the transport device bulges and aligns with the line of contact.
- an alignment device for copying machines in which the position of individually fed sheets of a recording medium can be changed before printing with a transport device which can be moved transversely to the transport direction.
- the sheet is first aligned parallel to the transport direction.
- the transport gap of the transport device running transversely, ie approximately perpendicular to the transport direction is closed, so that a line of contact is formed between the transport units. This line of contact between the transport units forms the stop for the leading edge of the sheet. If a record carrier sheet is now inserted into the copier, it is drawn in by means of the feed device upstream of the transport device and conveyed in the direction of the transport device.
- the feeder only ends the transport process when the sheet bulges between the feeder and the transport device.
- the arched record carrier sheet is under tension and its front edge lies evenly on the line of contact between the transport units of the transport device.
- the sheet is then gripped by the transport device and conveyed into the copier.
- a sensor device detects the side edge of the sheet and determines its position transversely to the transport direction and relative to the desired pressure position. If the position determined transversely to the transport direction does not correspond to the target pressure position, the transport device holding the sheet is stopped and moved transversely to the transport direction until the position of the sheet corresponds to the target pressure position. The transport process is then continued.
- the distance between the feed device and the conveyor device downstream of the transport device, which the sheet in the Copier transported be larger than the maximum possible length of a single sheet. This is the only way to ensure that neither the feed device nor the conveying device hold the sheet while it is aligned transversely to the transport direction by the transport device. Otherwise the sheet will be damaged during the alignment. Consequently, the overall length of the alignment device depends on the maximum sheet length and is of a correspondingly large size. At the same time, shorter sheets which are less than half as long as the sheets of maximum length cannot be transported by the alignment device, since the transfer of such a short sheet from the feed device to the transport device or from this to the conveyor device fails.
- the feeder releases the sheet to be aligned after it has been gripped by the transport device. This ensures in a simple manner that the sheet is only held by the transport device during the alignment transversely to the transport direction. Furthermore, in the constructive arrangement of the feed device to the transport device, no consideration has to be given to the actual sheet length, so that sheets of different lengths can be aligned on the one hand and the distance of the feed device to the transfer device on the other hand. port device can be kept low, whereby a small overall length for the alignment device is possible.
- the feed device has two conveyor units running transversely to the transport direction of the sheet. At least one of the two conveyor units can be moved between the transport position in which it rests on the other conveyor unit and the open operating position in which it is held at a distance from the other conveyor unit.
- Suitable conveyor units are, for example, rotatably mounted conveyor rollers, at least one of which is driven. The use of conveyor belts or tractor units is also possible.
- At least one clamping element is provided on the feed device, which biases the movable conveyor unit into the transport position.
- at least one actuating unit is provided on the feed device, which moves the movable conveying unit into the open operating position against the force of the tensioning element. In this way it is ensured that the feed device is ready for transport at all times and is only in the open operating position during the alignment of the sheet.
- a tensioning device on the aligning device which holds the transport device in a starting position transversely to the transport direction, in which the transport device is arranged approximately centrally to the transport path, along which the sheet is guided through the aligning device, before it grips the sheet becomes.
- the transport device is then moved against the force of the tensioning device.
- the tensioning device ensures that the transport device is in a defined starting position before it grips the recording medium. det.
- the transport device must be moved transversely to the transport device against the force of the clamping device during the process, so that it is mechanically clamped. A particularly high positioning accuracy is thereby achieved. Hydraulic or mechanical spring elements, which are each arranged on the two end faces of the transport device and are fastened to the frame of the alignment device, are suitable as tensioning devices.
- the sensor device preferably has a first edge sensor, which is arranged in front of the transport device, viewed in the transport direction. This first edge sensor detects the position of the side edge of the sheet in relation to the desired pressure position at the beginning of the alignment of the sheet. It is also advantageous if the sensor device has a second edge sensor arranged after the transport device, seen in the transport direction, which only determines the position of the side edge of the sheet when the transport device feeds the sheet to the transfer location of the single sheet printer or the copier. This makes it possible to continuously monitor the position of the side edge of the sheet with the aid of the first edge sensor and to continuously readjust the transport device during the process.
- a first and a second edge sensor are used at the same time, it is possible not only to determine the offset of the sheet, but also to determine whether the recording medium is drawn in at an angle by comparing the position values determined by the two edge sensors at the same time.
- Simple light barriers are particularly suitable as edge sensors, but also light-sensitive arrangements such as CCD arrays.
- the transport device is preferably moved transversely to the transport direction of the recording medium by means of a first drive.
- Servo drives are particularly suitable as the first drive, since they can be controlled very precisely.
- Stepper motors are also proposed as drives for the transport device, since these are len of the individual control pulses can be positioned very precisely and at the same time the position of the transport device can be determined by counting the individual control pulses.
- the first transport unit of the transport device is a transport roller extending transversely to the transport direction.
- a second transport unit at least one counter-pressure roller bearing against the transport roller with pre-tension is used. Both the transport roller and the counter-pressure roller can be designed with an elastic coating so that the sheet can be held securely.
- the transport takes place by means of a second drive which moves the transport roller.
- a servo drive or a stepper motor is also suitable as a drive here.
- so-called tractor units can be used as transport units, which pull the recording medium into the alignment device by means of conveyor belts.
- Figure 1 is a schematic diagram of an alignment device according to the invention.
- Figure 2 is a schematic representation of the processes involved in aligning a single sheet of a recording medium.
- FIG. 1 shows a basic illustration of an exemplary embodiment of an alignment device 10 which is used to align a single sheet 12 of a paper recording medium.
- the alignment device 10 has a transport device 14 shown approximately in the middle in FIG. 1, seen in the transport direction 16 of the sheet 12 the feed device 18 arranged in the transport device 14 and a conveyor device 20 adjoining the transport device 14 in the transport direction 16. Furthermore, the alignment device 10 is equipped with a total of four light barriers 22, 24, 26 and 28.
- the first light barrier 22 is arranged directly in front of the feed device 18, as seen in the transport direction 16, and emits a signal to the controller (not shown) of the alignment device 10 as soon as the sheet 12 is inserted into the alignment device 10.
- the second and third light barriers 24 and 26 are arranged in the immediate vicinity of the transport device 14.
- the second light barrier 24 is positioned in front of the transport device 14 as seen in the transport direction 16 and detects the sheet 12 as soon as it is fed to the transport device 14.
- the third light barrier 26, viewed in the transport direction 16, is arranged after the transport device 14 and serves to determine the side edge of the sheet 12 as soon as the sheet 12 has been gripped by the transport device 14.
- the fourth light barrier 28, which detects the sheet 12 as soon as it is fed to the conveying device 20, is fastened directly in front of the conveying device 20 in the transport direction 16.
- the use of light barriers 22, 24, 26 and 28 ensures that only one sheet 12 is in alignment device 10 during the alignment of sheet 12 by transport device 14, as will be explained below.
- the transport device 14 uses a transport roller 30 which is mounted in a frame (not shown) and extends transversely to the transport direction 16 of the sheet 12. Above the transport roller 30 there are three counter-pressure rollers 32 which are likewise held in the frame and which bear against the transport roller 30 under prestress and form a transport nip with the latter, through which the sheet 12 is conveyed.
- a roller drive 34 is arranged on the right end face of the transport roller 30 shown in FIG. This roller drive 34 displaces the transport roller 30 during the Transport of the sheet 12 in rotation, so that the sheet 12 is conveyed by the counter-pressure rollers 32 which are under prestress on the transport roller 30.
- the frame of the transport device 14 is held in guide rails (not shown) running transversely to the transport direction 16 of the sheet 12.
- One end of a leaf spring 36 or 38 is attached to each end of the frame of the transport device 14.
- the other end of the leaf springs 36 and 38 is fixedly connected to the frame 40 of the alignment device 10.
- an actuator 42 is fastened to the latter, the drive shaft 44 of which extends in the transport direction 16.
- the drive shaft 44 is equipped with a toothing which engages with a toothed rack 46 which is fastened to the frame 40 of the alignment device 10 and extends transversely to the transport direction 16.
- the transport device 14 If the actuator 42 is activated by the control (not shown) of the alignment device 10, the transport device 14 is moved along the guides against the force of the leaf springs 36 and 38 transversely to the transport direction 16 by the interaction of the drive shaft 44 with the rack 46. If the actuator 42 is deactivated, the transport device 14 moves back into its starting position due to the action of the leaf springs 36 and 38.
- the feed device 18 uses a feed roller 48 which extends transversely to the transport direction 16 and is rotatably mounted in a frame (not shown).
- a counter-pressure roller 50 is arranged above the feed roller 48.
- the counter-pressure roller 50 is rotatably supported at each of its ends on a pivotable plate 52 or 54.
- the pivotable plates 52 and 54 are fixed on a common axis A, which in turn is rotatably mounted on the frame (not shown).
- a coil spring 56 and 58 is also pushed onto the axis A.
- spiral springs 56 and 58 are used to pivot the Narrow plates 52 and 54 and thus the counter-pressure roller 50 biased in the direction of the feed roller 48 so that the counter-pressure roller 50 in a transport position in which the sheet 12 can be transported by the feed device 18, bears against the feed roller 48 under tension.
- An adjusting element 60 is also provided on each of the pivotable plates 52 and 54, of which only the adjusting element 60 of the plate 52 shown on the left can be seen in FIG. With the help of the actuating elements 60, the counter-pressure roller 50 can be moved against the force of the spiral springs 56 and 58 into an open operating position in which it is held at a distance from the feed roller 48.
- the feed roller 48 is set in rotation by means of a feed roller drive 62, so that the sheet 12 arranged between the feed roller 48 and the counter-pressure roller 50 resting thereon is conveyed.
- the conveying device 20 likewise uses a conveying roller 64 which extends transversely to the transport direction 16 and against which three counter-pressure rollers 66 bear under pretension.
- the conveyor roller 64 is rotated by means of a conveyor roller drive 68, so that the sheet 12 arranged between the conveyor roller 64 and the counter-pressure rollers 66 is transported.
- the first light barrier 22 detects the side edge of the sheet 12 shown on the left in FIG. 1 and emits a signal to the controller (not shown) of the alignment device 10.
- the control activates the feed roller drive 62 of the feed device 18 by means of the signal from the first light barrier 22, as a result of which the feed roller 48 pivoted into the transport position is set in rotation and the sheet 12 is drawn into the alignment device 10.
- the second light barrier 24 detects the front edge of the sheet 12 conveyed into the aligning device 10, it passes this signal on to the control.
- the control stops the feed device 18 until the fourth light barrier 28 has detected that the further sheet has left the alignment device 10. If the further sheet has left the alignment device 10, the control deactivates the roller drive 34 and, with the aid of the actuator 42, moves the transport device 14 back to its starting position, ie approximately in the middle of the transport path. The controller then activates the feed device 18 again, so that the sheet 12 to be aligned is drawn further into the alignment device 10. If, at the point in time when the control detected the signal from the second light barrier 22, there was no further sheet in the alignment device 10, the feed device 18 is not stopped, but instead pulls the sheet 12 into the alignment device 10 without interruption.
- the sheet 12 to be aligned arrives in the transport device 14, its front edge pushes into the transport gap between the transport roller 30 and the counter-pressure roller 32.
- the feed device 18 continues to feed the sheet 12 into the alignment device 10
- the sheet 12 arches between the feed device 18 and the transport device 14, as shown in FIG.
- the control of the aligning device 10 stops the feeding device 18, so that the sheet is held by the feeding device 18 and at the same time aligns with its leading edge on the line of contact due to the stresses in the sheet 12 caused by the curvature.
- the controller then activates the roller drive 34 of the transport device 14 so that the sheet 12 is drawn into the alignment device 10. As soon as the third light barrier 26 the front edge of the Detected sheet 12, the controller stops the transport device 14. The control then actuates the actuating elements 60 of the feed device 18, as a result of which the counter-pressure roller 50 is moved from its transport position, in which it bears against the feed roller 48 under pretension, into the open operating position, in which it is held at a distance from the feed roller 48. As a result of this opening movement, the feed device 18 releases the sheet 12, which relaxes and runs flat again along the transport direction 16. The transport device 14 then begins the alignment process, which is explained in more detail below with reference to FIG. 2.
- FIG. 2 shows a path-time diagram and a current-time diagram arranged below it.
- the path-time diagram shows the alignment process of the sheet 12 in a top view, the different positions of the sheet 12 being shown in dotted, dashed or solid lines.
- the setpoint pressure position which is labeled X- Q on the path axis, runs in a dashed line.
- the value XQ on the axis defines the starting position of the sheet 12 when it is drawn into the alignment device 10.
- the value XL defines a predetermined distance of the third light barrier 26 from the target pressure position, which should be 6 mm in this exemplary embodiment.
- the current-time diagram shows the signal curve 70 of the light barrier 26 and the signal curve 72 of the actuator 42, with which the transport device 14 is moved transversely to the transport direction 16.
- the sheet previously aligned by the alignment device 10 has left the transport device 14. Since the light barrier 26 is no longer interrupted, it generates a signal (shown hatched).
- the actuator 42 is activated, as shown in the signal curve 72, whereby the transport device 14 is moved again in its starting position. The return movement of the transport device 14 is completed at the time t.
- the third light barrier 26 detects the sheet 12 to be realigned, which is drawn into the transport device 14 with an initial position X Q.
- the third light barrier 26 is interrupted, which can be seen in the signal curve 70.
- the control detects the signal from the third light barrier 26 at time t3, it moves the feed device 18 into the open position, which releases the sheet 12, and then activates the actuator 42, which transversely to the entire transport device 14 and thus also the sheet 12 to be aligned Transport direction 16 moved to the left.
- the sheet 12 has been moved to the left so far that its position corresponds to the position XL of the third light barrier 26, this is no longer interrupted by the sheet 12 and no signal is generated, as shown in the signal curve 70.
- the control system recognizes that the sheet 12 is at the level of the third light barrier 26 and stops the actuator drive second drive 42.
- the control activates the actuator 42 in such a way that it moves the transport device 14 and thus the sheet 12 to the right transversely to the transport direction.
- the actuator 42 is operated by the control at a constant speed over a predetermined period of time. After this period of time at time tg, the controller stops the actuator 42, so that the transport device 14 and thus the sheet 12 remain in a certain position transverse to the transport direction 16. Since the actuator 42 had been activated at a constant speed for a predetermined period of time, the blade 12 was moved to the right a predetermined distance.
- This path section corresponds to the distance of third light barrier 26 to the target pressure position X D , so that the sheet 12 is from the time tg with its right side edge at the level of the target pressure position Xp.
- the control activates the roller drive 34 of the transport device 14 and the conveyor roller drive 68 of the conveyor device 20. As a result, the sheet 12 is transported out of the alignment device 10. As soon as the second light barrier 24 detects the rear edge of the sheet 12, the control deactivates the actuating elements 60 of the feed device 18, as a result of which the counter-pressure roller 50 is moved back into its transport position by the force of the spiral springs 56 and 58.
