Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a method of manufacturing a booklet of arbitrary paper size and thickness by wire comb binding, and in order to bind a booklet made of a plurality of sheet-like printing materials loosely, the wire binding element is a sheet-like The invention relates to a method of being received by a row of holes provided along an edge of a printing material.
[0002]
[Prior art]
Methods for producing booklets using so-called Wire-O wire binding elements (registered trademark) of various sizes are known, for example from EP-A-0095243 and EP-A-0095245.
[0003]
The Wire-O wire binding element is defined as a wire loop having a loop length L, a loop interval A, and a wire diameter D, arranged in parallel with each other, as shown in FIG. Is done. This Wire-O wire binding element is shaped into a Wire-O ring by a suitable closure device.
[0004]
The binding device according to the above mentioned patent specification is formed so that it can process shaped Wire-O wire binding elements with different loop spacings and different loop lengths.
[0005]
In general, the above-described devices have drawbacks, such as the need for wire binding elements required for such paper sizes and thicknesses in order to bind booklets of different paper sizes and thicknesses. It must be provided to the binding device in the form of an already shaped storage binding element (for example an element cut with respect to roll material or binding length). In order to be bound in different booklet sizes and thicknesses, a considerable number of stocks are required beforehand. Furthermore, in the case of a change in the form of a booklet to be produced, an apparatus suitable for transport and processing must be adapted to the requirements of different wire binding elements. Such a change in equipment requires a costly conveying device and a binding device structure, which is economical only when a large number of booklets having a certain thickness are produced. Therefore, it cannot be economically manufactured with a small production volume and requires a long time cost based on adapting the machine.
[0006]
From German Offenlegungsschrift 2 847 700 a method for producing wire bindings for blocks (booklets) etc. is known, in which the wire drawn continuously from the stock is corrugated by a reciprocating bending motion. The corrugated wire compact is then bent into a C shape perpendicular to the corrugated plane. Since a forming roller with a fixed diameter is used to bend the wire, only wire binding elements with a constant loop spacing and length can be produced.
[0007]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to improve the method of producing a booklet of arbitrary paper size and thickness by wire comb binding in the method as described at the beginning, and to determine each paper size and thickness of the booklet to be bound, It is to provide a method in which the wire binding elements can be produced directly during the binding process, depending on the binding element requirements.
[0008]
[Means for Solving the Problems]
According to the method of the present invention for solving this problem, at least one wire binding element harmonized with each paper size and thickness of the booklet is produced immediately before the binding process, if necessary.
[0009]
For this purpose, first, the paper size and thickness of the booklet to be bound are detected. Detection of the paper size and thickness of the booklet to be bound and possibly the hole type is performed by transmitting parameters from the preceding device to the electronic device and / or by the sensor technology. This is done by specifying the paper size and thickness, and possibly the hole type, and transmitting them to the electronic device.
[0010]
The production parameters for the wire binding element are then defined by the electronic device, and then the wire binding element is electronically and mechanically coupled by the device,
Supplying the wire bending device from at least one wire reservoir with a storage wire roll;

[0011]
【The invention's effect】
Various advantages are obtained by the method of the present invention. Fully automatic binding of the booklet is possible with a wire binding element produced as needed having an arbitrary loop length, loop width, wire diameter and number of loops corresponding to the maximum booklet width that can be processed. Changing or adapting the binding device is not necessary. Booklet binding can also be realized by a plurality of single binding elements having the same or different mutual spacing. In this case, a high binding speed can be obtained by binding the single binding elements together in time. Deformation of the wire binding elements produced on demand is avoided by automatic production and transport, so that the possibility of trouble is significantly reduced compared to conventional devices.

As shown in FIGS. 1 and 6, the wire storage unit 20 includes storage wire rolls 21, 22, and 23, and the storage wire rolls 21, 22, and 23 have different wire diameters (e.g., 0. A wire 1 having 8 mm to 1.2 mm). In this case, wires are used which are distinguished by different coloration and can be arranged corresponding to the aforementioned wire diameters. In detail, the wire 1 is looped by a wire bending device 40 (not shown). In this case, the loop length L and the loop interval A can be adjusted to values arbitrarily set by the electronic control unit 110. After reaching the number of loops set by the electronic control unit 110, the wire bending device 40 cuts the existing wire binding element 41.
[0015]
The conveying means 50 conveys the wire binding element 41 to an insertion device 80 (Einkaemmvorrichtung), which is not shown in detail, which is part of the bending and closing device 90. The printing material 11 is not printed or is printed on one or both sides by a printing device, stacked, provided with a row of holes 12 by a punching device and then aligned, and a stack of such printing materials 11 in sheet form is formed. The conveying means conveys to the bending and closing device 90. The wire binding element 41 is passed by the insertion device 80 through the hole row 12 of the sheet-like printing material 11 stacked and aligned, and is closed by the bending and closing device 90 so that Wire-O is formed. Next, the bound booklet is discharged from the booklet production apparatus 200 via the discharge apparatus 100 and stored.

Forming the indentation deforming part 61 at the center with respect to the loop length L (see FIG. 2) is also advantageous by appropriately feeding the casing 54 supporting the tongue 51 in the conveying direction of the wire conveying path 2. Incremental for each loop. An optical edge sensor (not shown) is used to define the loop center, which identifies the exact position of the wire loop in the bending device 60. The tongue 51 guided through the spindle 52 is transported in a direction perpendicular to the wire transport path 2 by a drive device 53 formed as a step motor, as schematically indicated by the arrow X in FIG. Is possible. In order to move the casing 54 in parallel to the wire conveyance path 2, guide grooves 55 are provided in the casing 54, and guide bars 56 attached to the casing of the booklet production apparatus 200 are provided in the guide grooves 55. Is engaged. The parallel movement with respect to the wire transport path 2 is performed by a suitable driving device (not shown). When it is necessary to correct the position of the tongue 51, the driving device 53 of the spindle 52 formed as a step motor is actuated appropriately by the electronic control unit 110.
