Definitions

  • the invention relates to a method and an arrangement for the lateral alignment of sheets according to the preamble of claim 1.
  • Method and arrangements for the lateral alignment of sheets in a conveying direction are conveyed in a sheet-processing machine sheet in which the sheets to be printed by means of a arranged below or in the feed table, in time with the incoming sheet from a drive to a 9.zieh Gay driven side pulling in a Detected starting position and promoted to a 9.ausrichtposition.
  • the position of the not yet page-aligned sheet is detected by the sensor and determines the individual drawing path for the sheet until it hits a side stop.
  • suction air is connected to the trained as a sucker Soziehorgan sooner or later to the constant running movement of the nipple and promoted the sheet of the teat fixed in position against the side stop.
  • the vacuum at the vacuum cleaner must be set very sensitively to the respective sheet to be processed. If the vacuum is high, it may damage the bow.
  • the object of the invention is therefore to provide a method of the type mentioned above and an arrangement for carrying out the method, so that the sheets are correct side aligned without damage.
  • the reaching of the page-alignment position of the sheet is detected by a sensor and a corresponding side-position signal is generated, by which the drive is actuated to end the side-pulling movement.
  • the sheet can be detected with a holding force of the Soziehorgans that can vary within a wider tolerance range and only has to be high enough to ensure a slip-free holding without leading to a deformation of the bow.
  • a sensitive adjustment of the holding force on each type of sheet to be processed is not required.
  • the secure holding of the bow avoids a relative movement between bow and 9.ziehorgan and thus a static charging of the bow.
  • the page puller can be triggered to detect the sheet, so that when the page alignment position is reached, the sheet is also released for onward transport.
  • the side position signal is fed to a control unit by the sensor, whereby a first stop signal is triggered in the control unit and supplied to the drive in a non-stop manner.
  • the object is achieved in an arrangement for carrying out the method, characterized in that the soziehorgan is acted upon with vacuum from a vacuum source suckers, which is movable transversely to the conveying direction of the sheet from a starting position to the Soausrichtposition movable by the drive, wherein for gentle detection of the arc Sucker can be a sucker plate.
  • For detecting and holding the sheet during the page orientation of the sucker is preferably connected via a switching valve with the vacuum source.
  • the switching valve is a 2/2-way valve, in which a switch position of the sucker with the vacuum source and in the second switching position of the sucker with atmosphere or an overpressure source is connected, then after reaching the Soausrichtposition is a switching from the first switching position in the second switching position and thus a venting of the nipple, so that the sheet is released from the nipple.
  • this can be a solenoid valve.
  • the senor may be adjustable to different Soausrichtpositionen, preferably the sensor is continuously adjustable to the different Soausrichtpositionen.
  • the senor may be arranged on a carrier which is adjustable transversely to the conveying direction by a motor drive, which can be controlled by the control unit.
  • Such a Einjust Schlieren preferably takes place in a maximum range up to 0.1 mm, but especially only in the range of a few 0.01 mm.
  • the carrier may be a carrier plate whose surface extends in the plane of the feed table.
  • a guide recess may be formed in the feed table or in the carrier plate, in which the nipple or the nipple plate is guided transversely to the conveying direction movable ,
  • the drive of the Soziehorgans is a servo motor, which can be an accurately driven and fast driving drive an electric motor.
  • the senor may be a non-contact sensor, wherein preferably the sensor is an optical sensor.
  • FIG. 1 a first embodiment of an inventive arrangement is shown.
  • a support plate 4 is arranged at least in a left or right edge region, the surface of which extends in the plane of the feed table 1.
  • a scissor lattice 5 is arranged, the upper, by Side edges of the scissor lattice 5 formed guide surface also extends in the plane of the feed table 1.
  • the support plate 4 is adjustably adjustable by a motor drive 6 transversely to the conveying direction 2 by a compensation path 14.
  • a suction plate 8 is guided transversely to the conveying direction 2 by a maximum pulling path 9 movable.
  • the suction plate 8 having a plurality of suction openings 10 which are open towards the top side can be driven in a mobile manner from the illustrated starting position, which is remote from the side edge of the carrier plate 4, in the direction of the side edge up to a side alignment position.
  • one of an electric servomotor 11 rotatably driven spindle 11 engages the suction plate 8 at.
  • the suction plate 8 is acted upon by a negative pressure on its underside, which can be supplied from a negative pressure pump 13 forming a vacuum source via a 2/2-way valve 12 of the suction plate 8.
  • an optical sensor 15 is arranged, whose position defines the Thisausrichtposition.
  • the 2/2-way valve 12 which is designed as a magnetic valve, is switched into the illustrated suction position, so that the suction openings 10 of the suction plate 8 be subjected to negative pressure. As a result, the sheet is sucked against the suction plate 8 and thus detected.
  • the suction plate 8 is now moved by means of the drive from the servo motor 11 from the initial position shown in the direction of the sensor 15 until the side edge of the sheet reaches the sensing or detection range of the sensor 15.
  • the sensor 15 detects the arrival of the side edge of the sheet in the page alignment position defined by the touch area and generates a side position signal which is fed to the control unit 16, which then terminates a first stop signal to the servomotor 11 with its side pulling movement.
  • a second stop signal in the control unit 16 which is the 2/2-way valve 12 is supplied so that it switches from its illustrated suction position into a ventilation position.
  • the front marks 18 in front of the contact sheet 3 then move from their vertical bearing or alignment position into a substantially horizontal position, so that the sheet, which is now completely aligned with its leading edge and one side edge, can be fed to the further processing machine in the sheet conveying direction 2.
  • the servo motor 11 moves the suction plate 8 back to its original position, so that the now next sheet can be detected and aligned in the same way as the previous sheet.
  • the sheets are fed either in a single-sheet stream or in a scale flow on the feed table 1 the contact plate 3 and to bear against the front lays 18.
  • this movement is small and has an order of less than 0.1 mm.
  • control unit 16 can be fed to the control unit 16 by means of a control station 17.
  • the alignment of the sheet can also be performed on bow-leading drums of the sheet-processing machine.
  • This embodiment is in FIG. 2 schematized illustrated.
  • FIG. 2 For example, one known arrangement for sheet feeding to a sheet processing machine such as a sheetfed press is shown.
  • a feed table 1 a plant drum 20, which is associated with a gripper system 21.
  • the sheet transport continues in the sheet conveying direction 2 via a sheet leading cylinder, which also has a gripper system.
  • the abutment drum 20 and the sheet guiding cylinder 22 may also be formed as so-called double-sized drums with two gripper systems arranged offset by 180 degrees.
  • the sheet transport finally takes place to a impression cylinder 23, which also has gripper systems and is designed as part of a printing unit 24 of the sheet-fed press.
  • FIG. 2 shows according to the first embodiment described above, designed as a belt table feed table 1, by means of which individual sheets, usually arranged in a submerged sheet flow, are conveyed in the sheet conveying direction 2 and an abutment sheet 3 to a system of front lays.
  • the front marks were at the boundary of this are arranged on a collision drum 20.
  • the leading marks could also be arranged on another sheet-guiding cylinder 22 or an impression cylinder 23 of the sheet-processing machine, which is arranged in a corresponding configuration in connection with the feed table 1.
  • the leading brands are here on the investment drum 20 in conjunction with there for the Sheet transport provided gripper systems 21 arranged. The latter applies to other drums or cylinders.
  • the conveyance of the sheets to these front edge alignment on the feed drum 20 serving front marks is carried out by means not shown conveyor systems without interruption in time to symbolically here with a printing unit 24 illustrated sheet processing machine.
  • the sheets no longer have to be stopped in their movement for the alignment at the front marks, since they are conveyed directly to the at the time of taking over the sheet at a slower speed rotating drum 20.
  • the leading brands are arranged in this case together with the grippers 21 and therefore arranged with these pivotally drivable relative to the sheet leading cylinder surface of the plant drum 20.
  • the carrier plate can preferably extend over the entire cylinder width or drum width and extend parallel to a gripper loading strip assigned to the grippers of the cylinder or the drum.
  • the alignment elements are then also arranged over the entire cylinder or drum width in the carrier plate.
  • the sheet holding grippers, the gripper assembly on the cylinder or the drum of the alignment movement of the alignment in the carrier plate can follow.
  • the gripper assembly 21 can be deflected laterally transversely to the sheet conveying direction 2.
  • the page orientation can also be performed with the gripper assembly 21 itself, the sheet is then moved by the grippers on quasi passive alignment elements in the support plate relative to the support plate.
  • the grippers of the gripper assembly are slightly raised and thus release the sheet during the movement of the alignment.
  • the sheet can then follow the alignment movement of the alignment elements when coupled thereto by suction or clamping means which may be parallel to the grippers, by friction or other type of frictional connection. After performing the Soausrichtnado the grippers are closed again and take over the further transport of the sheet in the now aligned at the front edge and on the side edge position.
  • Embedded in the support plate can thus also be provided in this embodiment designed as suction pads alignment elements. It is again provided to adjust the support plate of a motor drive transversely to the sheet conveying direction 2 adjustable by a compensation path. Furthermore, a sensor in the support plate is also provided here, by means of which the pneumatic control alignment movement of the alignment as the suction pads is feasible. The control takes place in the same way as described above for the first embodiment according to the invention.
  • the motor drive of the alignment in this case either promotes the arc with the grippers or the motor drive is directly connected to the gripper assembly and moves the sheet by a lateral deflection of the gripper assembly on the sheet leading cylinder.
  • the motor drive of the carrier plate is assigned according to the first embodiment on the sheet leading cylinder of the carrier plate.
  • this area is indicated as alignment area 19.
  • the page orientation can be made safer because it is carried out continuously and over a longer period of time.
