Definitions
- the present invention relates to a method for grooving envelopes according to the preamble of claim 1 and an apparatus for performing this method according to the preamble of claim 5.
- the structure of the paper structure is changed at this point.
- the paper fiber or the composite is pressed together. This change causes a reduction in the restoring forces, i.e. the envelope is easier to open or fold at this point without breaking the material.
- grooves are known.
- a groove is rotated, which is the most commonly used method today, the envelope passes through a pair of rollers consisting of a top tool and a bottom tool (female and male).
- the problem with this is the lack of directional stability, i.e. the groove or groove can move sideways.
- Another problem is that the material of the envelope is tumbled by the rotation. Under the microscope you can see that the edge breaks, especially on painted surfaces.
- Another method is to insert a groove using a slot iron.
- the envelope is loaded evenly by a small lifting movement and is thus compressed.
- This procedure delivers higher quality results because the grooves are made particularly clean.
- the cleaner the groove is inserted the higher the appearance of the bound book.
- Both processes are operated both manually and in machine operation. In any case, the distance between the grooves that limit the spine must be adjusted by hand.
- Two grooves b and c delimit the spine and lie between the glue area for the book spine and the glue areas for the side gluing. Grooves a and d can be introduced again along the other side of each side glue.
- the distance between the grooves a and b is equal to the distance between the grooves c and d. As a rule, this distance is about 5 mm.
- the distance between the grooves b and c is variable and depends on the thickness of the book block.
- the work process in the prior art must be carried out twice.
- the groove lines a and b are introduced by means of a so-called “twin iron”
- the groove lines c and d are accordingly introduced.
- the distance between the grooves b and c has so far always had to be set manually, for example when using a sliding iron by manually adjusting the stop for the envelope in the machine.
- this process is uneconomical due to the very complex set-up time and is therefore rarely used.
- the manual adjustment of the distance between the grooves b and c carries the risk of reading errors, which leads to inaccuracies.
- the book block has also previously 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 is later glued, rests smoothly. 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.
- 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 done in part by adding spacers or the like. This requires a certain amount of time, in particular 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.
- the solution consists in a method with the features of claim 1 and in a device with the features of claim 5. According to the invention, it is therefore provided that an automatic book block pliers with at least one movable stop surface is used to adjust the distance between the grooves and which by means of automatic book block pliers determined value for the thickness of the book block is used to automatically adjust the distance between the grooves.
- the device according to the invention is characterized in that it has a grooved iron with a stationary and a displaceable pair of tools, the displaceable tool pair being automatically adjustable to the desired distance between the grooves delimiting the book block by means of a control unit.
- the method according to the invention and the device according to the invention are user-friendly, allow a high degree of automation and higher performance, that is to say a higher throughput of envelopes. Double grooves can be made in a single operation using a slot iron.
- the method and the device according to the invention are preferably suitable for use in book production lines.
- the determined value for the thickness of the book block can be transferred to a control device for the grooving tool.
- the device according to the invention can therefore be operated as an "in-line” device which receives the digital values for the thickness of the spine from a previous processing station which has the book block pliers.
- the device according to the invention can also be used as a "stand-alone” device. Device are operated, in which the values for the thickness of the spine are entered, for example, using a keyboard.
- the device operating according to the method of the invention preferably a one- to five-pin binding machine, can therefore be provided with a book block pliers, which no longer has to be adjusted to the different block thicknesses. This measure is an important contribution too Automation in the area of small machines and thus reduces set-up times enormously. Another important aspect is that no tools are required.
- the value for the thickness of the book block is preferably determined by first opening the book block pliers to the maximum value and then closing it to receive a book block, the movement of the at least one movable stop surface or the respective one for opening and closing being opened and closed required time is measured and stored in a control unit and the difference between the two values is calculated and stored and the stored value is digitally transmitted to the control device for the grooving tool.
- a value can be added to the determined difference value which corresponds to the volume of the most voluminous paper contained in the book blocks to be recorded, in order to avoid errors caused by different paper volumes.
- the book block pliers (50) can have a fixed stop surface (51) and a movable stop surface (52) which are connected to one another via at least two axes (53, 54), the movable stop surface (52) along the axes (53, 54) is movable.
- toothed racks can be provided which are operatively connected to a toothed pinion, so that the movable stop surface (52) can be displaced by actuating the toothed pinion.
- the pinion can be actuated by means of an electric motor.
- Figure 1 is a schematic representation, not to scale, of a bound book with a cardboard cover with four grooves;
- Figure 2 shows the envelope of Figure 1 in an expanded view
- Figure 3 is a schematic representation of a grooving tool
- Figure 4 is a schematic perspective view, not to scale, of an embodiment of an automatic book block pliers
- FIG. 5a shows a side view of the book block pliers from FIG. 4;
- Figure 5b is a view of the book block pliers from Figure 4 from below.
- the bound book 1 consists of a book block 2 and a cardboard cover 3.
- the cover 3 has four grooves 4, 5, 6, 7.
- the distance between the grooves 4 and 5 is equal to the distance between the grooves 6 and 7 and is usually about 5 mm.
- the area between the grooves 4 and 5 or 6 and 7 is glued to the pages of the book blocks, so that the so-called page gluing results.
- Each pair of grooves 4, 5 and 5, 6 can also be referred to as a double groove, the outer grooves 4 and 7 pointing inwards towards the book block 2 and the inner grooves 5, 6 pointing outwards from the book block 2.
- the grooves 5 and 6 delimit the spine 8, i.e. that part of the cover 3 which later covers the back of the book block 2.
- the spine 8 is glued to the back of the book block 2. Therefore, the distance between the grooves 5 and 6 is variable depending on the thickness of the book block 2.
- FIG. 3 shows a device for carrying out the method according to the invention, namely a grooving iron 10.
- the grooving iron 10 consists of two upper tools 11, 13 and two lower tools 12, 14.
- the tools 11, 12 and 13, 14 each form a matrix and Patrice existing pair and have a device 15, 16, 17, 18 for introducing a double groove 4, 5 and 6, 7.
- the two upper tools 11 and 13 execute a synchronous lifting movement along the arrow A in FIG. 3.
- the height h of the lifting movement is preferably such that normal envelope grammages, ie from 170 to 300 g / m 2 , can be processed.
- This height h preferably measures just enough that the envelope 3 can be easily inserted into the tool.
- the height h is preferably fixed and need not be set separately by the operator of the slot iron 10.
- the distance between the two pairs of tools 11, 12 and 13, 14 must be set so that the resulting grooves 5 and 6 have the desired distance corresponding to the thickness of the book block 2.
- This setting is made automatically via a control.
- the desired value is taken from a previous processing operation in which the book block 2 is held by an automatically controlled book block pliers 50, for example the back processing for roughening the back of the book block 2.
- This value can either be read and separately, for example using a keyboard, can be entered into the device according to the invention ("stand-alone” device) or it can be digitally transferred directly from the control of the book block pliers to the control of the grooving iron 10 ("in-line” device).
- the grooved iron is designed in such a way that a pair of tools 11, 12 or 13, 14 is stationary and the other pair can be moved continuously along arrow B in FIG. 3, for example by means of a servomotor.
- the pair 13, 1 is fixed and the pair 11, 12 slidable.
- the envelope 2 is automatically fed to the device according to the invention in a manner known per se, for example via a bias tape in a defined feed direction along the arrow C. It is positioned along a defined stop or alignment edge 19.
- This edge can be an electrically, pneumatically or hydraulically movable stopper edge, for example for processing envelope sizes of different sizes.
- the arrangement of the fixed and displaceable pair of tools can also be exactly the opposite, that is to say, for example, in FIG. 3 with the same feed direction along arrow C, the pair 11, 12 is fixed and the pair 13, 14 is displaceable.
- the device operating according to the method according to the invention is preferably equipped with automatic book block pliers 50.
- An embodiment of this book block pliers 50 shown in FIGS. 6, 7a and 7b consists of a rear fixed stop surface 51 and a smaller front movable stop surface 52 or press plate, which are connected to one another via at least two axes 53, 54.
- the dimensions of the entire book block pliers are such that all common book formats from A6 to A3 can be processed. This also applies to the block thickness in the range of min. approx. 3mm to max. approx. 60 mm.
- the front stop surface 52 can be moved on the axles 53, 54 by a corresponding bearing guide (not shown). At the respective two ends of the axes 53, 54 racks are attached. Via a toothed pinion connected to a continuous axis, the front stop surface 52 is moved forward by motor, that is to say for opening, and to the rear, that is to say for closing. The movements of the pinion who which are incrementally counted and stored in a control unit. Thus, after the first opening of the book block pliers 50 to the largest possible opening width, z. Ex. 60 mm, entered a book block. The front stop surface 52 is moved inwards in the direction of the rear stop surface 51, so that the book block is pressed together.
- the difference between the resulting travel distance "and the total opening distance corresponds to the book block thickness. This value is saved. If subsequent, similar book blocks are processed, the book block pliers 50 are only opened by this determined and saved opening width. It is no longer necessary to adjust the opening width by hand.
- the measurement of the book block thickness can also take place over the time which elapses until the front stop surface 52, which is moved at a constant speed, is moved so far back that it comes to a standstill on the book block.
- This recorded value is also transferred to a servomotor which opens or closes the opening of the glue nozzle accordingly, so that a glue strip is applied in the required width corresponding to the book block thickness.
- This recorded value is also transferred to a further servomotor, which opens or closes the distance between two or more external tools accordingly. This is necessary for the preparation of the envelope.
- papers can have different volumes, i.e. some papers appear softer and can be pressed more. This phenomenon is taken into account by automatically adding an amount of e.g. five or ten mm is added. This ensures that all papers, even with different volumes, can be processed without any problems.
