Die Erfindung betrifft eine Einrichtung zur Herstellung gebundenen Schriftgutes mit repräsentativen Einbänden, wodurch Texte, Zeitschriften, konstruktive Darstellungen, Bildsammlungen, Vertragswerke, Angebote, Werbeschriften (Kataloge) in ansprechender Form, in kleinen bis mittleren Serien auf den Markt gebracht werden können.
Die Anwendung ist für den privaten und gewerblichen Gebrauch vorgesehen, insbesondere für Arbeiten in Architektur-, Ingenieur-und Konstruktionsbüros, sowie in Steuerbetatungs- und Rechtsanwaltskanzleien und auch Schulen, Verwaltungen oder Werbeagenturen.The invention relates to a device for producing bound written material with representative bindings, which texts, magazines, constructive representations, image collections, contracts, offers, advertising pamphlets (catalogs) can be brought in an appealing form, in small to medium series on the market.
The application is intended for private and commercial use, in particular for work in architectural, engineering and design offices, as well as in tax accounting and law firms and also schools, administrations or advertising agencies.

Zum Binden loser beschriebener oder anderweitig bedruckter Blätter in verhältnismäßig kleinen Auflagen gibt es bereits ausgefeilte technische Lösungen, die mehr oder weniger beschrieben sind und bisher zur Anwendung kommen.For binding loose written or otherwise printed sheets in relatively small runs there are already sophisticated technical solutions that are more or less described and are used so far.

Anhand der nachfolgend genannten technischen Lösungen soll prinzipiell der Stand der Technik dokumentiert werden.Based on the technical solutions mentioned below, the state of the art should in principle be documented.

Die schweizerische Patentschrift CH 677053 A5 stellt ein Gerät zum Binden von Blättern durch Erwärmen vor, wobei im Inneren eines oktogonalen Gehäuses eine Aluminiumschiene mit Ausnehmungen für Heizelemente angeordnet ist. Die Einrichtung gestattet das gleichzeitige Binden von 2 Mappen, wobei mittels eingebauter Elektronik die Schaltdauer der Kaltleiterheizelemente zeitlich regelbar ist. Die kompakte Bauweise hat einerseits den Vorteil der leichten Bedienbarkeit aber andererseits den Nachteil, dass die Taktzeiten zwischen Heizen und Kühlen hoch sind und damit Energie "verschenkt" wird. Zur Verkürzung dieses Zeitnachteils werden zusätzliche Lüftungsschlitze im Boden des Gehäuses vorgeschlagen.The Swiss patent CH 677053 A5 discloses an apparatus for binding sheets by heating, wherein an aluminum rail with recesses for heating elements is arranged in the interior of an octagonal housing. The device allows the simultaneous binding of 2 folders, whereby by means of built-in electronics, the switching time of the PTC thermistor heating elements is temporally adjustable. The compact design on the one hand has the advantage of ease of use but on the other hand, the disadvantage that the cycle times between heating and cooling are high and thus energy "is given away". To shorten this time disadvantage additional ventilation slots in the bottom of the housing are proposed.

In der europäischen Patentanmeldung EP 0 489 336 A1 wird ein Tischgerät zum Binden eines Bündels von Papieren, entlang einer gemeinsamen Kante, vorgeschlagen. Der technische Vorgang der Herstellung gebundener Produkte vereint die Schritte des Laminierens und Bindens miteinander. Vorgefertigte Einbände können hier nicht gemeinsam mit losen Blättern verwendet werden. Die Einbringung der Heizenergie wird über mehrere Blöcke wärmeleitenden Materials, insbesondere aus Aluminium bestehend, gewährleistet, wobei der Abkühlvorgang technisch nicht weiter unterstützt wird. Als aufwendig und mechanisch anfällig ist der Transport mittels mehrerer Rollenpaare zu sehen.In the European patent application EP 0 489 336 A1 For example, a tabletop device is proposed for binding a bundle of papers along a common edge. The technical process of producing bonded products combines the steps of laminating and binding. Prefabricated bindings can not be used together with loose sheets. The introduction of the heating energy is ensured by several blocks of heat-conducting material, in particular made of aluminum, guaranteed, the cooling process is technically not further supported. As complex and mechanically prone to see the transport by means of several pairs of rollers.

Die US-Patentanmeldung 5 829 938 stellt ebenfalls ein heizbares Tischgerät vor, mit dem ein vorgegebener Papierstapel mittels eines mit Klebstoff benetzten L-förmigen Bindebandes nach Einlegen und elektrischer Erwärmung "gefaßt" und anschließend durch manuelles Schwenken, im Sinne des "Abkantens", ein kurzer Druck im zu verklebenden Bereich aufgebracht wird. Besondere Maßnahmen zur effektiven Nutzung einmal eingebrachter Heizenergie und deren Abschirmung zum Zwecke des kurzzeitigen Abkühlens sind nicht vorgesehen, wobei auch ein unabhängig davon nachfolgendes "Verpacken" in einen Einband noch zusätzlich erfolgen muß.The U.S. Patent Application 5,829,938 also provides a heated tabletop device, with which a given stack of paper by means of a wetted with adhesive L-shaped binding tape after insertion and electrical heating "captured" and then applied by manually panning, in the sense of "Abkantens", a short pressure in the area to be bonded becomes. Special measures for the effective use of once introduced heating energy and their shielding for the purpose of short-term cooling are not provided, with an independent subsequent "packaging" in a cover must be made additionally.

Gemäß der europäischen Patentanmeldung EP 0 841 192 A1 gibt es nunmehr ein elektrisch beheizbares Tischgerät mit Mehrfachaufnahmen definierter Breite zum Binden von Blättern oder Bögen, wobei durch zeitgesteuertes Beheizen der mit den Blättern/Bögen bestückten Einbände, die wiederum eine Klebstoffeinlage besitzen, der optimale Zeitpunkt des "Auswurfes" durch schaltbare Magnetkontakte einleitbar ist. Die zu diesem Zeitpunkt noch vorhandene Erwärmung im Heizelement kann, bei nicht sachgerechter Einstellung der Heizzeit, zum "Verwerfen" des Einbandes führen.According to the European patent application EP 0 841 192 A1 There is now an electrically heated table top device with multiple recordings defined width for binding sheets or sheets, which by timed heating of the sheets / bows stocked bindings, which in turn have an adhesive insert, the optimal time of the "ejection" by switchable magnetic contacts can be introduced. The still existing at this time heating in the heating element, in case of improper setting of the heating time, lead to "discarding" of the cover.

Diese dem Stande der Technik entnommenen Nachteile gilt es nunmehr zu überwinden, wobei es Aufgabe der Erfindung sein soll, die energetischen Verhältnisse bekannter Bindegeräte zu verbessern, das Binden von Einbänden aus metallischen oder nichtmetallischen Materialien gleichermaßen zu ermöglichen und zudem mit einer die Bindedauer optimal steuernden Technik auch unterschiedliche Formate zu bindender Blätter oder Bögen zu ermöglichen, wobei es keinerlei Einschränkungen hinsichtlich verwendbarer Bindemappen geben soll.These disadvantages of the prior art, it is now overcome, the object of the invention is to improve the energetic ratios of known binding devices to allow the binding of bindings of metallic or non-metallic materials alike and also with a binding time optimally controlling technology also to allow different formats to be bound sheets or sheets, with no restrictions on usable binders should give.

Erfindungsgemäß wird die Aufgabe wie folgt gelöst, wobei die grundlegenden erfinderischen Gedanken im Patentanspruch 1 niedergelegt sind und in den Ansprüchen 2 bis 11 die weitere Ausgestaltung vorgenommen wird.According to the invention the object is achieved as follows, wherein the basic inventive idea laid down in claim 1 and in the claims 2 to 11, the further embodiment is made.

Das zentrale Element des Bindegerätes stellt sich als eine schnell aufheizbare und schnell abkühlbare längliche und in sich stabile Keramikfläche dar, an deren Unterseite ein Heizelement angebracht ist. Die etwa paarweise oder zu mehreren angeordneten induktiven Sensoren, die sich unter der Keramikfläche befinden, lösen bei Einlage einer Bindemppe die Aufheizung der Keramikfläche aus, bis zum optimalen Erweichungspunkt des im Rücken eines metallischen Einbandes deponierten Klebematerials, wobei über die Heizfläche dieser Keramikfläche verteilte Thermosensoren überwachend wirken. Damit werden mittels exakt vorgegebener Temperaturen und Steuerzeiten, die elektrisch regelbar sind, Fehlbindungen vermieden sowie Verwerfungen des Bucheinbandes durch Überhitzung von vornherein ausgeschlossen.
Neben der Verwendung von Einbänden mit steifer metallischer Einlage sind auch Mappen produzierbar, die in anderer Weise konzipiert sind, nämlich Herstellung aus plastischen Werkstoffen, Pappe oder aus kaschierten Werkstoffen bestehen.
Zu diesem Zweck befinden sich neben den vorgenannten induktiven Sensoren ein oder mehrere mechanisch beaufschlagbare Sensoren, die in der Breite der Heizfläche, wobei durch Absenken eines Quersteges, der beidseits federbelastet ist, der Heizkontakt durch Betätigung eines optischen oder Mikroschalters (-tasters) einleitbar bzw. mittels der Messung über die vorhandenen thermischen Sensoren jederzeit abschaltbar ist. Ein weiterer, in einem Querspalt der keramischen Heizfläche nach oben partiell austretender, z.B. in Form einer Drahtwendel konzipierter Sensor steht bei Belastung in elektrischem Kontakt mit einem Kontaktdraht / Widerstandsdraht, wodurch gemessen an der Breite eines willkürlich beschaffenen Einbandes bzw. seines Gewichtes mit den zu bindenden Blättern der elektrische Widerstand mikroelektronisch erfaßbar ist und den Aufheiz-und Abschaltvorgang der Thermosensoren unterstützt, indem die erforderliche Zeit der Erwärmung bestimmt wird.
In einer, die Funktion sichernden zusätzlichen Ausbildung besitzt der Sensor an seiner Unterseite innen einen angeordneten Schlauch nebst Justiermöglichkeit, zur Einstellung eines definierten Druckes, wobei die durch Einlegen eines Einbandes eingebrachte Belastung in Wirkverbindung mit einem druckerfassenden Sensor und/ oder Schalter steht. Letzterer löst sodann den Beginn der Aufheizung der keramischen Heizfläche aus.The central element of the binding device turns out to be a rapidly heatable and rapidly cooled elongated and inherently stable ceramic surface, on the underside of which a heating element is attached. The inductive sensors located approximately in pairs or more, which are located below the ceramic surface, initiate the heating of the ceramic surface upon insertion of a binder, up to the optimum softening point of the adhesive material deposited in the back of a metallic cover, monitoring thermal sensors distributed over the heating surface of this ceramic surface Act. Thus, by means of precisely predetermined temperatures and control times, which are electrically controllable, faulty connections are avoided and distortions of the book cover due to overheating are excluded from the outset.
In addition to the use of bindings with a stiff metallic insert also folders can be produced that are designed in other ways, namely made of plastic materials, cardboard or laminated materials.
For this purpose, in addition to the aforementioned inductive sensors one or more mechanically acted upon sensors, in the width of the heating surface, wherein by lowering a transverse web which is spring-loaded on both sides, the heating contact by actuation of an optical or microswitch (pushbutton) can be introduced or by means of the measurement via the existing thermal sensors can be switched off at any time. Another, in a transverse gap of the ceramic heating surface upwards partially exiting, for example designed in the form of a wire helix sensor is under load in electrical contact with a contact wire / resistance wire, thereby measured on the width of a random cover or its weight with the binding Scroll the electrical resistance is detected microelectronics and supports the heating and shutdown of the thermal sensors by the required time of heating is determined.
In one, the function securing additional training, the sensor has on its underside inside an arranged hose together with adjustment possibility to set a defined pressure, wherein the introduced by inserting a cover load is in operative connection with a pressure sensing sensor and / or switch. The latter then triggers the beginning of the heating of the ceramic heating surface.

Die Lage des Sensors kann dabei in der Mitte der keramischen Heizfläche oder am Ende derselben vorgesehen werden, wobei bei letzterem ein Anschlag den Abschluß der keramischen Heizfläche bildet.
Die technologisch günstige Beherrschbarkeit des Aufheizens und Abkühlens der keramischen Heizfläche wird einrichtungsgemäß noch dahingehend befördert, dass ein eingebauter Ventilator die Kühlung bewirkt.
Die Zeit für Erwärmung (Heizzeit) kann auch durch einen Drucksensor in Abhängigkeit vom unterschiedlichen Gewicht der Bindemappen gesteuert werden.
Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden. Dazu wurden zeichnerische Darstellungen anhand der Figuren 1-16 genutzt.

The position of the sensor can be provided in the middle of the ceramic heating surface or at the end thereof, wherein in the latter case a stop forms the conclusion of the ceramic heating surface.
The technologically favorable controllability of the heating and cooling of the ceramic heating surface is still conveyed to the effect that a built-in fan causes the cooling.
The time for heating (heating time) can also be controlled by a pressure sensor depending on the different weight of binders.

In einem Thermo-Bindegerät befindet sich an der Oberseite des Gehäuses 5 die keramische Heizfläche 1. Zur Stützung der zu bindenden Blätter 14 nebst Einband 13 werden Haltebügel 23 paarweise über der seitlichen keramischen Heizfläche 1 vorgesehen.
Die keramische Heizfläche 1 an deren Unterseite ein Heizelement integriert bzw. ein Peletier-Element angebracht ist, trägt an ihrer Unterseite ferner ein oder mehrere induktive Sensoren 3 und Thermosensoren 2 die einerseits den Erwärmungsvorgang auslösen und andererseits nach Erreichen des optimalen Schmelzens des Bindeklebestoffes und Einsinkens der Blätter 14 in den vorhandenen Einband 13 den Heizungsprozeß abschalten.
Durch die unterschiedlichen Werkstoffe der Bindemappen wird das Erreichen der Schmelztemperatur des Klebers beeinflußt. Unterschiedliche Werkstoffe erfordern andere Bindetemperaturen und andere Bindezeiten. Zum Erkennen von Einbänden / Bindemappen ohne Metalleinlage werden Mikrotaster oder optische Sensoren, die über einen Quersteg 15 beaufschlagbar sind, alternativ eingesetzt.
Unabhängig von dem Bindemappenwerkstoff ermittelt der Drucksensor 22 aus dem Gewicht einer Mappe die dazugehörige Bindebreite und die dafür nötige Bindezeit bei vorgegebener Bindetemperatur.
Mit der Anordnung eines Sensors bestehend aus den Elementen flexibler Schlauch 6, Schalter 7 und Drahtwendel 8, im Bereich der Keramikheizfläche 1 wird die Bindemappenbreite erkannt und die Heizzeit genau geregelt.
Dem gleichen Zweck dient auch die Drahtwendel 8 bei Berührung des Kontaktdrahtes / Widerstansdrahtes 10 infolge Belastung durch die Bindemappe. Der dadurch veränderte Widerstand im Kontaktdraht / Widerstandsdraht 10 wird als Breite der Bindemappe zur Heizungsregelung benutzt. Zweckmäßigerweise befindet sich bei seitlicher Lage der Drahtwendel 8 neben dieser der Anschlag 9. Unter der Drahtwendel 8 ist weiterhin der flexible Schlauch 6 mit einem Kolben 11 und der Stellschraube 12 zur Justierung des Ausgangssignals angeordnet.
Entlang der keramischen Heizfläche 1 kann an ihrer Unterseite ein / oder eine Reihe von Piezoelementen angeordnet werden, die während des Schmelzens des Bindeklebstoffes das Einsinken der Blätter 14 in einen Einband 13 durch Schwingung und Vibration befördern.
Zur schnellen Kühlung gebundener Einbände werden unterhalb, seitlich der keramischen Heizfläche 1 ein oder mehrere Motorenlüfter 4 positioniert, wobei mittels eines schwenkbaren, motorbetriebenen Abdeckbleches 19 die erzeugten Luftströme lediglich den Einband/ die Einbände 13 erreichen und die Restheizenergie der keramischen Heizfläche 1 möglichst nicht angegriffen wird. Der Antrieb für das Abdeckblech 19, d.h. der Motor, ist mit dem Positionzeichen 20 bezeichnet. Zu diesem Zweck ist die keramische Heizfläche 1 zusätzlich mittels Motor 21 abschwenkbar. Der Prozeß der Kühlung wird vorteilhafterweise durch zuschaltbare Peltier-Elemente in der Nähe der Einbände 13 zeitlich forcierbar gestaltet. Es kann vorgesehen werden, dass ein Quersteg 18 als Aufstellfläche für das Bindegut dient, für den Fall, dass die keramische Heizfläche 1 zum Zwecke der Kühlung seitlich verschiebbar ausgebildet wird.In a thermo-binder is located on the top of the housing 5, the ceramic heating surface 1. To support the sheets to be bound 14 together with cover 13 headband 23 are provided in pairs over the lateral ceramic heating surface 1.
The ceramic heating surface 1 at the bottom of a heating element integrated or mounted a Peletier element, carries on its underside also one or more inductive sensors 3 and 2 thermosensors on the one hand trigger the heating process and on the other hand after reaching the optimum melting of the binding adhesive and sinking the Leaves 14 in the existing cover 13 to turn off the heating process.
Due to the different materials of the binders, the achievement of the melting temperature of the adhesive is affected. Different materials require different binding temperatures and other binding times. For detecting binders / binders without metal insert, micro-probes or optical sensors, which can be acted upon by a transverse web 15, are used alternatively.
Regardless of the binding binder material, the pressure sensor 22 determines from the weight of a folder the associated binding width and the necessary binding time for a given binding temperature.
With the arrangement of a sensor consisting of the flexible hose element 6, switch 7 and wire coil 8, in the area of the ceramic heating surface 1, the binder wall width is detected and the heating time is precisely controlled.
The wire helix 8 also serves the same purpose when the contact wire / resistance wire 10 is touched as a result of loading through the binder. The thus changed resistance in the contact wire / resistance wire 10 is used as the width of the binding binder for heating control. Conveniently located at the side position of the wire coil 8 in addition to this stop 9. Under the wire coil 8, the flexible hose 6 is further arranged with a piston 11 and the adjusting screw 12 for adjusting the output signal.
Along the ceramic heating surface 1, one or a series of piezoelectric elements can be arranged on its underside, which convey the sinking of the sheets 14 into a cover 13 by vibration and vibration during the melting of the binding adhesive.
For quick cooling bonded bindings are positioned below, one side of the ceramic heating surface 1 one or more motor fan 4, 19 by means of a pivotable, motorized cover plate 19, the air currents generated reach only the cover / bindings 13 and the residual heat energy of the ceramic heating surface 1 is not attacked , The drive for the cover plate 19, ie the engine is designated by the position mark 20. For this purpose, the ceramic heating surface 1 is additionally swung off by means of motor 21. The process of cooling is advantageously designed temporally forcibly by switchable Peltier elements in the vicinity of the covers 13. It can be provided that a transverse web 18 serves as a footprint for the binding material, in the event that the ceramic heating surface 1 is formed laterally displaceable for the purpose of cooling.
