Definitions

  • the invention relates to a method for pressing a book block with rounded back according to claim 1 and an apparatus therefor according to claim 14 and a book production line with such a device.
  • each individual signatures comprising several pages of a book.
  • individual pages can be linked directly.
  • the signatures are first folded into stacks until a desired page size is available for a book block.
  • the folded sheets of a book block are precisely back to back superimposed and tied there, so that a common flat block back arises.
  • the procedure is analogous, so that a book block with a flat block spine is also created.
  • the rounding, the signatures and / or single sheets are displaced in a direction perpendicular to the block spine parallel to each other.
  • the middle folded sheets emerge with their backs from the flat block spine and there is a round back of the book block.
  • Other rounding methods work in addition to the above-described roll round principle, for example, the so-called. Hammer beam principle.
  • the interchangeable, mostly concave-shaped tools used for the known squeezing in a press beam are available in a narrow-stepped manner and are exchanged to suit the rounding of the back of the book block.
  • the replacement of these tools is usually done in a manual process and is expensive.
  • a book production line for the industrial production of books requires a fast automatic setup of each device of the book production line for job changes, especially for small and very small runs, which are understood as so-called on-demand orders and a single-book production.
  • this is hindered when manual setup processes are required.
  • the book block is clamped with rounding between two bars.
  • movements of the beams and the rounding devices are coordinated.
  • the roundness of the spine is determined by sensing the thickness of the book block used and by manual presetting.
  • the scan specifies a swing curve of the roller pressing off the spine.
  • the roller passes for pressing alternately, sometimes several times, holding the book block held in position on an arcuate path adapted to the back rounding.
  • this solution has due to the taking place in one and the same position rounding and pressing a very high mechanical complexity and a very low productivity.
  • rollers or plates which are either pressed only vertically against the back of the book block or stroke in a combined arrangement of a pressing and rounding a scan following the back.
  • the object of the invention is to provide a method and a device for high-quality pressing of a book block, which can be carried out automatically or which can be operated automatically and does not require a change of order due to replacement of tools.
  • the book block to be wiped off by the method or apparatus has a rounded spine and a longitudinal axis running along the spine, and according to the invention is subjected to the sequentially proceeding process steps described below.
  • the book block is first clamped on both sides in a region near the back parallel to the longitudinal axis of the rounded back between two clamping jaws. Subsequently, a compact is at least once moved against the rounded back of the firmly clamped book block, thereby perpendicular to the longitudinal axis and in the middle or at least approximately in the middle of the rounded back placed on this. In the subsequent pressing, the compact is moved over at least a portion of the spine. The compact presses the book block parallel to the longitudinal axis over the back away, where it follows at least one infinitely pre-selectable, lying in a plane perpendicular to the longitudinal axis of the back plane trajectory.
  • Preselectable means that the requirements of previous processes or changed orders can be met by adjusting parameters of the method or device. Preselecting also means that settings control the press device before or while the book block is being clamped. Such an adjustment may also occur for quality reasons during a job, such as when the speed of book production varies.
  • the device according to the invention has a clamping device and a pressing device.
  • the clamping device two clamping jaws are arranged parallel to each other.
  • the book block can be aligned with its back parallel to its longitudinal axis between the jaws, for example, after a feeder has raised or lowered the book block in the correct position.
  • the jaws serve for clamping the book block on both sides.
  • the jaws are mounted on each other, usually in the horizontal direction, so that the book block can be clamped in a region near the back between the clamping jaws.
  • the pressing device has a movably mounted compact and is used for vertical movement of the compact perpendicular to the longitudinal axis against the back of the book block and for lifting the compact from the book block.
  • the parallel to the longitudinal axis of the spine aligned press body is placed in a preselectable position on the back.
  • the compact is in the position assumed by the placement in the pressing device of a continuously selectable path of movement over the back of the book block movable.
  • the trajectory lies in a plane spanned perpendicular to the longitudinal axis of the spine.
  • the movement of the compact usually begins with placement in or near the center of the book block and subsequently describes an arcuate path. Due to this from the book block center outwardly extending path of the compact material displacement takes place in the back of the book block. With the material displacement is accompanied by a plastic deformation of the back, whereby the desired Abpress bin is achieved.
  • the plastic deformation caused by the compact under the support of the clamping jaws can, for example, be constant from the inside to the outside. It is considered advantageous if the plastic deformation increases from the book block center to the outside. As a result, the leaves of the finished book can be relieved because the back is stabilized by the plastic deformation.
  • Corresponding courses of the trajectory can be stored and retrieved product-related or derived from format parameters of the products to be produced, so that an automated processing of small, very small and individual editions is possible.
  • the at least one movement path of the compact is predetermined by a variably configured gear.
  • On the gear acts a first actuator.
  • the actuator adjusts the transmission according to a specification, before the compact is moved on the preselected thereby, at least one trajectory over the back of the book block.
  • the gearbox can be integrated as a robust component in the pressing device and can be steplessly controlled externally via the first actuator.
  • the compact is first moved in a first portion of the trajectories from the center of the back outwards to a first side of the book block before the compact lifted from the back of the book block and following another trajectory again to the center of Back is moved, but without having contact with the back. There, the compact is placed again on the back of the book block and presses this, at least another section of one of the trajectories following, from the center outwards to an opposite, second side of the book block.
  • the compact is moved on its way from at least one of the two sides of the book block to the center of the back on a path which is opposite to the trajectory of the compact on its way from the center to one of the two sides of the book block having different radius. If the movement path of the compact to the middle of the spine has a larger radius, the lifting of the compact from the back is advantageously integrated into the respective trajectory. In this type of pressing is avoided that disturbances in a once pressed-off portion of the back result, for example, by repainting the same portion in the reverse direction.
  • the compact can also be moved on a path to the center of the back, which has a relation to the trajectory of the previously performed pressing smaller radius, whereby the book block can be advantageously further pressed.
  • the at least one movement path of the compact is determined by means of a control unit from book block parameters and transmitted by means of the first actuator to the transmission.
  • the compact body presses at least a portion of the back several times.
  • the first actuator can also adjust the transmission during the pressing, so that the section can be pressed in each case with increasing pressure. Repeated overpainting of the back may be beneficial for certain materials. If, in such cases, the same pressure were to be applied to the back in just a single sweep, or in other words a simple squeeze, it could possibly lead to destruction.
  • the advantage here is possibly in quality improvements. There is thus a possibility to react in particular to changes in the choice of material.
  • the trajectory or trajectories are determined in dependence on a single or several book block parameters, such as the width, the material or the type of binding of the book block, or the curvature of its back.
  • the compact is independent of the preselected trajectory during pressing against a resistance of the back movable to realize an overload protection, so that exceeding a maximum pressing pressure is avoided by avoiding the trajectory.
  • an overload protection ensures a high level of quality and a high level of operational safety.
  • the transmission is moved together with the compact vertically in a stationary frame.
  • a placement of the compact on and a lifting of the compact from the back are thus possible without changing the arrangement of the compact in the transmission.
  • a control unit and an actuator designed in particular as a drive are required in a minimal case.
  • a format adjustment device can be provided for the superimposed vertical movement of the compact.
  • this will be the top one corrected setting and lifting of the compact corrected by a vertical actuator shortened or extended a distance between a fixed point and the compact in the vertical direction.
  • the transmission for moving the compact according to a first embodiment, at least two by means of the first actuator horizontally and preferably symmetrically displaceable, designed as a carriage gear elements each having two groove curves.
  • the transmission has at least two by means of the first actuator horizontally and preferably symmetrically toward each other or away from each other movable, constructed as a lever gear elements each having a rotatably mounted in a respective pivoting crank lever.
  • the compact is mounted by means of a traverse in the Nutkurven or the crank levers.
  • the two embodiments for the implementation of the transmission are basically the same effect.
  • the first embodiment represents a certain extent a simplification compared to the second embodiment, since pivot points are eliminated.
  • Other alternative embodiments of the transmission with coupling, crank and rocker come for similar implementation into consideration.
  • the embodiments may be performed with multiple components, for example with four transmission elements.
  • the traverse travels the trajectories in the groove curves, after the transmission elements have been moved relative to each other if necessary. What is needed is such an adjustment of the transmission, for example, when switching from a thinner to a thicker book block or book blocks with different curves.
  • the designed as a lever gear elements are shifted from each other. In both embodiments the first actuator acts exclusively in horizontal directions on the two gear elements. As a result, a different path of movement of the compact is established in the transmission.

  • the pressing body of alternative embodiments has a convex pressing surface facing the back of the book block to be pressed.
  • This compact is preferably designed as a partial or solid cylinder.

  • a crank lever is rotatably mounted in the pivot points, wherein in the crank lever, connecting them together, a parallel to the longitudinal axis of the back aligned, connected to the compact cross member is coupled.
