Definitions

  • the invention relates to a device and a method for handling flat wire binding element preforms, the wire binding element preforms representing semi-finished products of wire binding elements.
  • wire binding elements are typically used in binding devices for the loose connection of a brochure consisting of a plurality of sheet-shaped printing materials by means of wire comb binding, in particular the so-called Wire-O TM wire binding (registered trademark).
  • Wire-O wire binding elements are understood to mean wire loops S spaced parallel to one another with a loop length L, a loop spacing A and a wire diameter D. These are formed into a Wire-O-ring by means of suitable locking devices.
  • the wire binding elements are usually provided pre-formed for such binding devices in order to accommodate different binding requirements, such as the thickness and format of the brochure on the loop spacing, the loop length, etc.
  • Devices that produce the wire binding elements with different parameters such as loop spacing, loop length and number of loops are part of the prior art. However, changing the parameters has so far required considerable intervention and modification of the device for producing the wire binding elements.
  • a method for producing a wire binding for blocks etc. in which a wire continuously withdrawn from a supply is formed by bending back and forth into a wave-shaped structure, the wave-shaped wire structure subsequently transverse to the plane of the waves in a C-shape is bent.
  • Forming rollers with fixed diameters are used for bending, so that only wire binding elements with fixed loop spacing and length can be produced.
  • Binding devices for the production of brochures, which use so-called Wire-O TM wire binding elements in different sizes, are known, for example, from European patent applications EP 0 095 243 and EP 0 095 245. There is also an overview of different binding methods in H. Kipphan "Handbook of Print Media", pages 861 ff; Springer Verlag (2000).
  • the binding devices for the abovementioned patent applications are designed in such a way that the processing of preformed wire-O wire binding elements with different loop spacings and lengths is made possible.
  • the binding elements required for binding brochures of different formats and thicknesses are in the form of a number of binding element stocks that have already been formed, e.g. as roll material or as elements cut to length, must be made available to the binding device.
  • a considerable number of stocks is necessary.
  • several magazines of the necessary wire binding elements are usually to be made available, and the magazine can be changed manually or automatically.
  • these magazines require a lot of space.
  • such a magazine also represents a financial advance, whereby it is not ensured that all pre-bent wire binding elements will actually be used later.
  • these wire binding elements In the course of the binding process, these wire binding elements have to be inserted into a row of holes in the sheet-shaped printing materials that make up the brochure.
  • the automated handling of these stored wire binding elements is not trivial due to the considerable expansion of the stored wire binding elements and their flexible properties as well as their large dimensional tolerance ranges in all three dimensions, this applies in particular to the process of inserting the wire binding elements into the perforated row of a brochure to be bound. This insertion is done by hand in many of the commercially available devices, which is uneconomical for larger runs.
  • the often bought Pre-bent wire binding elements are deformed by transport damage and can then only be assembled manually, because the machine actually intended for this only tolerates deformations to a limited extent.
  • the devices suitable for transport and processing are to be adapted to the requirements of the different wire binding elements.
  • This retrofitting requires complex constructions of the transport and binding devices and only makes the binding process economical if larger quantities of a brochure thickness are produced in one format. Smaller runs are therefore uneconomical to produce and require a longer time due to the machine adaptation.
  • This object is achieved with a device according to the features of claim 1 and with a method according to the features of claim 17. Further features emerge from the subclaims.
  • the unit that provides the wire binding element preform can, on the one hand, be a unit that makes the wire binding element preform of the device according to the invention available from a magazine.
  • the unit that provides wire binding element preform can be a unit that produces the wire binding element preform immediately before.
  • the insertion unit advantageously comprises exactly one insertion module in order to insert the flat wire binding element preforms into the row of holes in a stack of sheet-like printing material.
  • the wire binding element preform comprises a number of wire loops which have the same number of holes as are to be inserted in the stack of sheet-like printing materials.
  • wire binding element preforms can be used that have a number of wire loops that is less than the number of holes in the stack of sheet-form substrates.
  • a plurality of wire binding element preforms can be inserted next to one another in the row of holes in a stack of sheet-shaped printing materials, possibly at different distances from one another.
  • the plug-in unit can comprise a plurality of parallel plug-in modules which operate synchronously or asynchronously. It is also conceivable that the plurality of wire binding element preforms into the holes of a stack sheet-like printing materials are inserted sequentially and the individual wire binding element preforms are assigned to the holes in the stack of sheet-like printing materials and inserted by suitable means. For this purpose, a relative movement in the direction of the row of holes between the plug-in unit and the stack can be provided, either by moving the plug-in unit or by moving the stack.
  • the transport unit has an endless transport belt.
  • This transport belt is advantageously made of plastic, flexible and low in wear.
  • Wire binding element preforms with different loop lengths L are processed in a device for flexible binding of book blocks or brochures of different thicknesses by means of wire comb binding.
  • the width of the transport belt is matched to the loop length L of the wire binding element preforms, such that the wire binding element preforms with the shortest loop lengths L laterally project over the transport belt on the one hand with the wire base and on the other hand with the wire loop tip, the lateral projection of the wire loop tip not being absolutely necessary.
  • a link chain as a transport element is also conceivable, which is equipped with small spring-loaded wire holders.
  • the wire base comes to rest at a predetermined distance outside the transport belt. This ensures that the wire binding element preform on the transport belt can be safely taken over by the plug-in unit.
  • the belt of the transport unit has teeth which, due to their geometry, support alignment of the wire loops.
  • the wire loops are aligned essentially parallel to the teeth on the conveyor belt.
  • the parallel alignment of the wire loops to one another is of particular importance, since the wire loops are to be inserted through parallel holes in the stack of sheet-like printing materials.
  • the parallel alignment results in a sufficiently large contact between the wire loops and the transport belt.
  • the teeth mutually chamfer the wire loops into the spaces between the teeth, thereby improving the alignment of the wire loops during the takeover of the wire binding element preform by the unit that provides the wire binding element preform.
  • the teeth are at a distance from one another which essentially corresponds to the width of the wire loops.
  • magnets are arranged within the endless transport belt, which pulls the flat wire binding element preform onto the transport belt.
  • the holding force of the wire loops on the transport belt caused by the magnets is chosen so large that the wire loops of the wire binding element preform can also be held securely on the transport belt against deformation of the wire binding element preform.
  • deformation is understood to mean the deviation of the shape of the wire binding element preform from the ideal shape of the wire binding element preform. Such deformation occurs, for example, when the wire base describes a curve shape.
  • Such a curve shape is caused by the summation of angular deviations of the individual bending points in the wire binding element preform.
  • the wire loop tips either gap apart or are pressed together.
  • the deformation can be a twisting of the wire binding element preform, that is to say a helical deformation of the wire binding element preform.
  • Such deformations can occur through the magazining of the wire binding element preform or through the production of the wire binding element preform itself.
  • the holding force of the magnets is at least so great that the wire loops do not slip while they are exposed to considerable acceleration and deceleration forces during transport on the conveyor belt.
  • the considerable acceleration and deceleration forces come about due to the wire-loop-like inclusion of the wire binding element preform on the transport unit.
  • the transport unit must always advance the transport belt by one increment in time with the device which provides the wire binding element preform.
  • the holding force of the magnets has to be low enough so that the plug-in unit following the transport unit is able to lift the wire binding element preform from the transport unit.
  • the magnets are permanent magnets.
  • the magnets are electromagnets that can be switched on and off with a controller. Permanent magnets are preferred over electromagnets because they are cheap on the one hand and on the other hand do not require a power supply or other electronics for control.
  • the holding force of the magnets can be optimally adjusted by the magnetization of the magnets, the width of the conveyor belt and the distance of the magnet system from the wire loops on the conveyor belt.
  • the transport unit has a star wheel, which guides the flat wire binding element preform in wire loops onto the transport base. This enables the rounding in the entrance area of the transport belt to be bridged in particular, since the star wheel at this point protrudes beyond the transport belt in the direction of the unit that the wire binding element preform provides.
  • a wire base backdrop is provided in the entrance area of the transport unit, which laterally aligns the wire base in order to achieve a predetermined lateral distance between the wire base and the transport belt.
  • This exact lateral registration of the wire binding element preform is important so that the further processes, in particular the takeover and insertion by the insertion unit, are reproducibly guaranteed can be.
  • the wire loops come out of the device with a certain deviation from the predetermined path, which provides the flat wire binding element preform.
  • the wire base backdrop therefore has an entrance funnel that guides the wire base to an alignment segment within the backdrop. This inlet funnel proves to be particularly advantageous when the first wire loop of a wire binding element preform is to be gripped by the transport unit.
  • the conveyor belt of the device according to the invention initially stands still during the production of the first two loops, only to become clear the third wire loop to move synchronously with the work cycle of the previous unit.
  • This is advantageous because the beginning of the wire binding element preform cannot get caught in the star wheel and is kept at the right distance at the top prong, so that, due to production, too large gaps between the wire loops are still correctly captured by the star wheel and in the spaces between the conveyor belt be pressed.
  • the plug-in unit has a rake plate, the rake plate having vertical rake fingers that are regularly spaced, the distance between the rake fingers essentially corresponding to the wire loop distance.
  • the number of rake fingers In a one-piece design of the insert unit, the computing plate corresponds to the maximum number of holes provided in the stack of sheet-like printing materials, and are therefore designed for the largest format of the stack of sheet-like printing materials to be processed.
  • the rake plate has at least as many rake fingers as the longest wire binding element preform to be processed has wire base segments.
  • the transport unit leads the flat wire binding element preform to the insertion unit in such a way that the computing fingers are assigned to the wire base segments, so that the center of the computing fingers essentially coincides with the center of the wire base segments.
  • the insertion unit has a prism plate which has notches which are aligned with one another and are assigned to the wire base segments. Rake fingers and prisms in the prism plate enable three-point mounting of the wire base segments of the wire binding element preform.
  • the notches aligned with one another define the plane in which the wire binding element preform is located when it is subsequently handled by the plug-in unit.
  • the transport unit has movable wire loop support elements which support the wire loops in a defined manner during handling by the plug-in unit.
  • the wire loop support elements are particularly advantageous when it comes to wire loops of great length, that is to say with wire binding element preforms for books with many pages.
  • the wire loop support elements can ensure that the wire loop tips are at the same height as the wire base. This is necessary in order to be able to ensure that the wire loop tips are securely inserted into the holes in the stack of sheet-like substrates, regardless of the format, that is to say regardless of the length of the wire loops.
  • the computing plate, the prism plate and the wire loop support elements are movably connected to form a plug-in module and this plug-in module is jointly mounted, driven and controlled in such a way that the plug-in module can move the wire binding element preform horizontally and vertically parallel to the wire base.
  • the horizontal and vertical movement of the wire binding element preform parallel to the wire base results from a superimposed, pivoting movement and a horizontal movement of the plug-in module.
  • the radius of the pivoting movement essentially corresponds to the height difference to be overcome between the plane in which the wire binding element preform is located on the transport unit and the plane on which the holes are in the stack of sheet-like printing materials. This difference in height can be reproduced in a simple and precise manner by the pivoting movement.
  • the rake fingers plunge substantially vertically behind the wire base of the wire binding element preform on the transport belt and then essentially horizontally pull the wire binding element preform backwards into the prisms of the prism plate.
  • the wire binding element preform is only displaced by a small distance in comparison to the loop length L in order to avoid damage to the wire binding element preform or the jacket of the wire binding element preform as far as possible.
  • the vertical movement of the rake fingers is achieved by superimposing the swivel movement and the horizontal movement in the plug-in module.
  • the wire loop support elements are inserted into the loops of the wire binding element preform after the wire base has been fixed between the wire fingers and the prisms.
  • the wire loop support elements have three-area fixing surfaces in the longitudinal direction, which are adapted to the wire diameters and are spaced apart from one another to correspond to the width of the wire loops. In this way, a three-sided support of each leg of a wire loop can be achieved.
  • the length of the wire loop support elements is the shortest length of the wire loops adapted to the wire binding element preform which is to be handled by the device according to the invention.
  • the wire binding element preform is lifted vertically from the transport unit.
  • the wire binding element preform can be detached from the transport unit with as little damage as possible.
  • the device has a control which adapts the forward movement of the transport unit to the clock frequency of the upstream device.
  • this is a mechanical stepping gear with a summing gear which is coupled to the unit which makes the wire binding element preform available in loops. This makes it possible to implement the operating states “stand”, “transport in cycles” and “transport quickly in cycles”.

After the wire binding element preform 41 is lifted off the transport belt 21, the transport unit 20 is ready to receive the next wire binding element preform 41.
  • the device according to the invention is in a basic position.
  • a stack of sheet-like printing materials 11 with aligned holes 12 are clamped in a pair of pliers 70, so that the holes 12 of the sheet-like printing materials 11 are located in an insertion plane for the wire binding element preform 41.
  • C-formers 50, 50 ' are located above the insertion level
  • O-formers 60, 60' are located below the insertion level and are spaced according to the thickness of the booklet 10 to be bound, in such a way that, in the position assumed, they act as fanning-out preventers for the sheet-like form
  • Printing materials 11 act, in particular when the tongs 70 pivot the sheet-shaped printing materials 11 into the intended position from below. As a result, individual spread sheet-like printing materials 11 are aligned.
  • the second C-former 50 ′ moves down into the centering position for the flat loop-shaped wire binding element 41, as shown in FIG. 10-2.
  • the second C former is in the centering position when the centering funnels 54 ′ of the second C former 50 ′ are aligned with the holes 12 in the sheet-like printing materials 11.
  • a flat wire binding element preform 41 is then inserted through the holes 12 in the sheet-like printing materials 11.
  • the flat wire binding element preform 41 is pushed in as far as possible with the tips 41s in the centering funnels 54 'of the second C-former 50'. In this position, the flat wire binding element preform 41 is still fixed in this position by the insertion unit 100.
  • it can also be a plurality of flat wire binding element preforms 41, as described above and shown in FIGS. 4a and 4b.
  • a single flat wire binding element preform 41 is always assumed in the following, although a plurality of flat wire binding element preforms 41 make no difference for the device according to the invention and the method according to the invention.
  • the O-formers 60, 60 ′ move up in the Y direction and plunge between the loops S of the flat wire binding element preform 41.
  • the O-formers 60, 60 'then move in the X direction to the correct engagement point for a C-shape of the wire binding element 41 "which is to be manufactured first.
  • This C-shape which is to be manufactured first of all depends on the loop length S, and thus in turn on the diameter of the finished O-shape and thus on the thickness of the booklet 10.
  • the O-formers 60, 60 'then move in the Z direction with their lugs 62, 62' over the loops S until the Noses 62, 62 'cover the loops S in width.
  • the O-formers 60, 60 ′ subsequently clamp the wire binding element 41 toward the brochure 10 by rotation about provisional pivot points (not shown). Up to this point, the flat wire binding element preform 41 has stopped in the centering funnels 54 'of the second C-former with the tips 41s. As soon as the wire binding element preform 41 is clamped in this position by the O-formers 60, 60 ', the plug-in unit 100 releases the wire base, because for the further process of O-forming. the wire binding element 41 "is fixed in position by the C-former 50, 50 'or the O-former 60, 60'.
