Definitions

  • the present invention relates to an apparatus for the production of printed products, comprising an arrangement of interacting rollers and a device for adjusting the center distance of two rollers according to the preamble of claim 1.
  • Paper and / or board processing machines with an arrangement of a plurality of mutually parallel rolls are known, which comprise means for adjusting the roll distances from each other.
  • the font DE 602 14 133 T2 discloses such a machine in the form of a machine for the production of corrugated cardboard. This comprises a first corrugating roller which cooperates on the one hand with a second corrugating roll to wave a paper web, and on the other hand with an adhesive cylinder for applying adhesive to the peaks of the paper web and a pressure roller feeding a second paper web, all said rollers and cylinders with their Axes are arranged parallel to each other.
  • the adhesive cylinder is supported in a swinging structure which is pivotable about axes parallel to the rolls.
  • a pair of first eccentrics are disposed above the plane defined by the axes of the glue cylinder and the first corrugating roll, which serve as a stop for the swing construction and are independently adjustable to serve a precise parallel alignment of the glue cylinder with the first corrugating roll.
  • a further eccentric is provided, which is arranged opposite the pair of first eccentric relative to the said plane, and allows pivoting of the swinging construction around the stop serving as a pair of first eccentric and thus adjusting the gap width.
  • the adhesive cylinder has a freewheel and is driven such that its peripheral speed is slightly lower than the peripheral speed of the corrugated paper web transported on the first corrugating roller.
  • the freewheel is equipped with sensors that monitor whether a drive torque is applied via the freewheel on the adhesive cylinder. This allows indirect monitoring, whether a drive of the adhesive cylinder on the freewheel or on the first corrugating roll transported paper web and thus, whether the gap width allows an adhesive transfer.
  • the largest possible gap width is initially set via the additional eccentric, in order subsequently to reduce the gap with the machine running until a drive of the adhesive cylinder over the corrugating roll is ascertained.
  • the actually set gap width remains unknown, so that during each adjustment this slow approach is required anew and can only be done while the machine is running and not at a standstill.
  • such a gap width adjustment is heavily dependent on the material properties of the paper web, the adhesive cylinder and possibly on the adhesive cylinder adhesive adhering. Too high an approach speed of the adhesive cylinder to the corrugating roll leads to narrower gap widths than desired in connection with the inertia of the information processing of the drive monitoring.
  • document DE-A-.2008 013315 discloses an apparatus according to the preamble of claim 1.
  • the object of the invention is to provide a device of the generic type, which improves the adjustability of the nip.
  • the invention achieves the object by a device having the features of claim 1.
  • Advantageous developments of the invention are characterized by the features specified in the subclaims.
  • the device for producing printed products comprises at least two cooperating and forming a pair of rollers, which are arranged parallel to each other and together form a gap and of which a first roller is pivotally mounted about a pivot axis parallel to the rollers, that by pivoting the first roller around the pivot axis, the gap width of the gap formed by the roller pair is changed.
  • at least one pivot arm is provided, which is arranged pivotably about the pivot axis of the first roller and receives the bearing of the first roller, so that the pivoting of the pivot arm, the first roller is pivoted.
  • the device comprises a linear guide and along this guide linearly movable reference element whose position corresponds along its trajectory of the gap width of the gap formed by the at least one pair of rollers.
  • the gap width is mapped in a linear reference system and is characterized in a particularly simple manner and precisely detectable without having to capture the gap forming and rotating rollers themselves.
  • the device preferably comprises a first drive as a pivot drive drivingly connected to the swivel arm.
  • a controllable drive as a rotary actuator, which is controlled by a controller of the device. This way, even heavy rolls can be swiveled and an automation of the gap setting is made possible.
  • an adjustable first stop is provided, which limits the pivoting movement of the pivot arm and thus the first roller on one side.
  • the adjustable first stop is arranged such that the smallest achievable by the pivot drive gap determines.
  • a second drive is associated with the adjustable first stop, which is drive-connected with this. In particular, in a control of the second drive by the control of the device an automated gap width adjustment is possible.
  • a mitschwenkender and said reference member displacing driver is arranged on the pivot arm, which transmits the pivotal movement of the pivot arm and thus the first roller to the reference element.
  • the driver engages in the manner of a slotted guide in a guide track of the reference element, which is designed so that it converts the pivotal movement of the pivot arm in a linear movement of the reference element, wherein there is a proportional relationship between the position of the reference element along its linear trajectory and the gap width , In this way, the gap acted upon by a constant factor can be read off exactly from the position of the reference element without the need for further arithmetic operations, in particular the use of trigonometric formulas.
  • the first roller comprises a shaft shoulder, which engages as a driver in the guide track of the reference element, so that position errors of the reference element due to manufacturing tolerances can be further reduced.
  • this shaft paragraph serves as a seat for a cam roller running in the guideway to decouple the slotted guide of rotation of the roller and thus to reduce their wear.
  • the device comprises a measuring device which detects the position of the reference element along its linear trajectory.
  • This measuring device supplies the control of the device with data, which are interpreted as the position of the reference element and thus as a gap width.
  • a non-contact displacement measuring system is used in the measuring device, which has no mechanical wear.
  • a magnetic sensor mounted on the reference element and moving with this magnetic strip and a frame-resistant and the magnetic strip across an air gap scanning is provided.
  • a reverse arrangement with magnetic stripe fixed to the frame and sensor attached to the reference element is also conceivable, but less advantageous due to the necessarily bending in the pivoting of the first roller line of the sensor.
  • the gap setting of the device forms a control loop, which is closed via the pivot drive, the measuring device and the control of the device.
  • the device in this case comprises a controllable drive, which allows any pivoting angle, so that can be dispensed with end stops. This way is an automated and very Precise adjustment of the gap width is possible, which eliminates reading and manual correction by an operator.
  • the gap setting of the device forms a control loop, which is closed via the actuator of the adjustable end stop of the pivoting movement, the measuring device and the control of the device.
  • this retains the advantage of allowing very simple drives, which allow pivoting from a first predetermined by a stop end length in a second predetermined by a further stop end position and back.
  • the gap width is predetermined by the first adjustable stop as described above.
  • a device with two as described and complementary control circuits also offers greater flexibility in the design of the movement curves for gap width changes.
  • pivot arm as an eccentric, which allows a simple and robust construction and high precision of the pivotable mounting of the first roller.
  • nip is adjustable in a very simple manner and with very high repeatability to different substrate thicknesses or to different plate thicknesses, so that the usability of the printing unit with respect to these parameters significantly expanded can be.
  • Sheet feeder with a gap adjustment of the transport gap according to the invention can be adjusted very easily, precisely and repeatably to different substrate thicknesses, without damaging sensitive sheets.
  • Roller pair 1 shown comprises a rotatable first roller 2 and a parallel to this and also rotatable second roller 3 , which together form a gap 5 with gap width 6 .
  • Both rollers 2 , 3 are driven by electric motors in a known manner, wherein the direction of rotation 31 of the first roller 2 of the direction of rotation 32 of the second roller 3 is only partially shown opposite.
  • the second roller 3 is mounted stationary in a machine frame, not shown.
  • the first roller 2 is movably mounted with variable gap width 6 to the second roller 3 .
  • a device is provided, which end of the first roller 2 comprises a pivot arm 8 which is mounted about a parallel to the rollers 2 , 3 pivot axis 7 pivotally mounted in the machine frame, not shown.
  • this pivot arm 8 the first roller 2 is mounted and thus pivotable together with the pivot arm 8 about the fixed frame pivot axis 7 , so that the gap width 6 between the first roller and the second roller is determined by the pivoting movement 33 .
  • a drive 9 which acts on the pivot arm 8 .
  • a pneumatic cylinder 9 is used, which pivots the pivot arm 8 with the first roller 2 selectively in a first end position or in a second end position.
  • the drive 9 is controllably connected to a controller 22 of the machine.
  • the according to Fig. 1 upper end position is determined by a frame-fixed first stop 10 .
