Definitions

  • the present invention relates to a device for processing sheet edges in the Production of books according to the preamble of claim 1 and a method for Editing sheet edges according to the preamble of claim 13.
  • All currently known methods are based on a back or sheet edge processing, which in essentially from a rotating tool platform in the form of a disc or Metal cross or similar exists, which is equipped with small knives, grooved pins or other teeth and turns parallel to the bottom edge of the sheet.
  • This tool platform or the axis of rotation is included a motor, which, depending on the tool configuration in individual cases rotates at a relatively high speed, but in any case exerts a considerable force on the book block to be able to record all sheet edges to be processed.
  • the book block is in a book block pliers with a certain paper notice, usually 7 to 15mm, which the individual leaves are pressed together.
  • the book block is as accurate as possible, in individual cases with a deviation of a fraction of a millimeter, is held in its position.
  • an extremely high force of the pliers is required to to hold the book block in place.
  • the pliers pressure is often not sufficient more and cannot be enlarged technically.
  • the block display since the book block is at right angles to the tool while the sheet edges are being processed, the block display, especially in the case of smaller machines, must be counterbalanced, for example with a type Shear bar ", to be kept in shape.
  • hot processing known as hot melt
  • hot glues including adhesives based on polyamide or polyurethane
  • Two shot processes or other processes.
  • the hot processing is essentially based on the clamping effect after the hot glue has cooled.
  • Cold processing uses so-called dispersion adhesives.
  • the cold glue binding is essentially based on the fact that the aqueous phase seeps into the prepared sheet edge, penetration forces are created by the water content on the one hand and by the capillary active bond of the paper on the other hand, which ensure that the adhesive penetrates into the sheet edges however, this physical process is the best possible back processing, in which the paper fibers are gently uncovered, especially when using aqueous dispersions, there must be no adhesive infeed due to, for example, too strenuous back processing.
  • Cold processing is generally preferred because the books so bound are better Laying behavior shows as the books bound by hot processing, in which the Clamping effect of the hot melt prevents the spine from being level when the book is opened lies.
  • the book display is deflected according to the direction of rotation of the tool.
  • the book block itself is always heavily loaded laterally across the entire width, because the tool in principle only that front or, in the case of counter-rotating tools, the rear blade cuts or tears and then how a plow is pushed through the stack of paper.
  • the exposed Fibers because the tool always works parallel to the lower edge of the book block, also deformed in parallel, i.e. deflected to the side. This makes it difficult to apply the glue and reduces the strength the bond.
  • the book block After processing and gluing the sheet edges, the book block passes through one or more processing stations, which take care of cutting, roughening or leveling the book block.
  • the object of the present invention is therefore a method and an apparatus the above Provide type that do not have the disadvantages described and a gentle, Allow even sheet edge processing without placing a heavy load on the book block.
  • the solution consists in a device with the features of claim 1 and in a method with the features of claim 13.
  • the present invention is therefore based on a completely different design principle.
  • Separate Milling discs are next to each other with a small distance from each other on at least two Axis systems arranged in pairs with mounting axes for one or more milling discs.
  • the axle systems are mounted so that each pair is parallel to the lower edge of the block or to the Sheet edges, but arranged opposite to each other.
  • the axis systems of each pair are in one Angle arranged at an angle to each other. Seen in the direction of the pliers, at least one rotates left axis of each pair clockwise and the at least right axis of each pair counterclockwise clockwise.
  • each milling disc processes only a small part of the book block and does not have to go through slide the entire book block. This results in less effort, from which it follows that the pinch pressure can also be reduced. There is also less noise pollution.
  • the peripheral speed of the milling discs is such that there is a clear removal the bottom edge of the sheet comes. This exposes the fiber and loosens the immediate one Prevents the environment of a fiber. There is no hitting or tearing of the sheet edges instead of.
  • the position of the outermost milling discs also corresponds to the maximum to be machined Book block thickness.
  • the angle of attack of the milling disks ensures that no paper waste is released into the environment outside the device according to the invention.
  • the removal of paper is not, as in the prior art, over the entire book block width pressed ", but is transported away according to the radius of the milling disk immediately after the cutting device has been engaged, usually at an angle of approximately 135 degrees. This is achieved in that the milling disk does not run parallel to the book block like the tools known in the prior art
  • the paper is removed radially and discharged with the air flow downwards.
  • the exposed fibers are brushed downwards and not, as in the prior art, brushed forwards or backwards so that they are vertical and optimal for the Glueing are prepared.
  • the number and spacing of the milling discs depend on the type of back processing in individual cases e.g. Cutting, milling, roughening or leveling, of the chosen diameter and thickness and the number of cutting devices per milling cutter. Due to the arrangement of the milling discs, as well as by choosing a certain speed compared to the pliers speed, an even, flat removal of the sheet edges is achieved.
  • the diameter of the milling discs and the height of the removed paper are proportional to each other, since the Paper is removed by attacking the cutting devices at the zenith of the milling disk. So prepared Sheet edges are optimally prepared for gluing, with penetrable adhesives works and therefore requires an appropriate adhesion between the sheet edges.
  • the advantages of the invention are thus that the processed paper notice in two, however opposing directions are deflected and thereby cancel each other out. Because of the special The counterweight or the counter cutting edge are dispensed with if the receiving axes are arranged to one another. Due to the special arrangement of the milling discs, only a small amount of pliers pressure is required.
  • the glue can be applied parallel to the book fiber as it is for optimal adhesion of the Envelope is desirable.
  • There are also advantages when processing paper with a line since there is no longer any lateral deflection of the paper notice and thus the milling disks capture the paper fibers and not just the line, so that better penetration of the Fibers with glue and so better adhesion of the envelope are possible.
  • a first embodiment of the present invention provides that at least two in pairs and arranged at an angle of inclination to one another and rotatable in opposite directions to one another Receiving axes are provided which are equipped with two or more milling disks.
  • the left Axis rotates clockwise and the right axis rotates clockwise.
  • a second embodiment of the present invention provides that at least instead three synchronously driven smaller axes arranged in pairs are provided, which are arranged parallel to the direction of the book block, the two axes of each Pair are mutually counter-rotating and each axis is equipped with a single milling tool is.
  • the left axis of each pair clockwise and the right axis of each pair counterclockwise.
  • each axle of a pair is driven separately but evenly, for example by electric motors by means of one belt drive each.
  • the left axis system is preferably at an angle of approximately 3 to 12 degrees from the center right and the right axis system at an angle of approx. 10 to 25 degrees from the center to the left assembled.
  • the degrees mentioned here are determined by the length of the tool, i.e. the Axes, according to the pliers speed and the maximum book block width, which with the inventive device to be processed.
  • the diameter of the milling discs can be, for example, 10 to 50 mm.
  • 50 milling cutters can up to 80 teeth can be provided, which can additionally have a grinding angle of, for example, 30 degrees.
  • a larger area of the blade edges can be cut cleanly by teeth with a ground angle become.
  • the milling discs only touch the edge of the book block at its zenith. This will wear out reduced because the surface of the milling discs is kept small and by the Rotation is constantly changing.
  • the length of the axis systems can be different and depends on the correlation between Setting angle and maximum book thickness.
  • the length assembly is preferably offset. With the same Setting angle of 5 degrees is z.
  • the right axis system of a pair is preferably a multiple longer than the left axis system. This ratio changes when the setting angles are changed. The shorter the axis systems are, the more force is exerted on each milling disc.
  • the milling discs on the shorter, for example, left axis system can have more teeth than those on the longer right axis system, for example.
  • the shorter axis system can, for example, 3 to 5 milling disks and the longer axis system has 9 to 12 milling disks at an angle to the vertical of 3 up to 12 degrees (longer axis system) and 10 to 25 degrees (shorter axis system).
  • edit the rear milling disks of the longer axis system the central areas of the spine, where there is no significant distraction.
  • a further advantageous development of the device according to the invention provides that it is a corresponding mounting unit is infinitely adjustable in height or that several Cutting devices arranged one behind the other in the pliers running direction with increasing height are. This gives the operator the opportunity to determine the amount of paper removal himself and adapt to the requirements of the individual case.
  • the device according to the invention can be provided with a suction device, so that the processing of the book block takes place under negative pressure. Because of this and additionally through the angle of attack The milling discs ensure that there is no paper waste in the area outside the device according to the invention is delivered.

  • the book block In the case of softcover book production, the book block has so far been entered into the book block pliers by hand or via an automatic feeder in such a way that the lower edge, to which the cover will later be glued, lies flush. Even edges are required for a later even glue film.
  • the opening or width of the book block pliers depends on the book block thickness. In the currently known methods and machines, the book block pliers must be set to the required book block thickness by hand, and usually with the aid of tools, in a time-consuming manner. This is sometimes done by adding spacers or similar. This requires a certain amount of time, especially in view of the fact that, for example, single-jaw machines are mainly used for short runs with different block thicknesses and especially for the so-called on demand "area. This would ultimately mean that the book block pliers must be manually adapted to the processing block thickness.
  • the book block pliers can be provided with a spindle drive.
  • the book block is pressed in the book block tongs and so over the different processing stations transported. This transport takes place on all machines using a simple one Chain.
  • Lighter and more unstable machines are mostly single chains, e.g. Bicycle chains. Multiple chains or more stable single chains are often used for heavier machines used.
  • Such a chain with a length of, for example, 3.5 meters consists of approximately 350 chain links and Thus, depending on the chain arrangement, from approx. 700 chain links or chain bearings.
