Abstract

The invention relates to a device for producing bound written material with representative covers, for marketing texts, magazines, constructions plans, collections of drawings, contracts, offers and promotional literature (catalogues) as required in small to medium series. A heatable ceramic surface (1) with an integrated heating element has several inductive (3) and thermal sensors (2) on its underside, for detecting covers with a metal inlay and for controlling the heat output. Said inductive sensors (3) are partially also supplemented with sensors with microswitches (16), optical sensors (17) and additionally, a pressure sensor (22) if the device is to be used for binding covers consisting of non metallic materials at the same time. The very short time for heating up the ceramic heating surface (1) made technically possible by the invention and the use of the stored temperature is made optimal use of through an internal flap system which is motor-operated. Integrated ventilators (4) ensure controlled ducted cooling which can also be supported by Peltier elements embedded in the ceramic heating surface (1). The inventive device can be used for binding different formats (DIN A4, DIN A5) and thicknesses.

Description

Thermo-Bindegerät Thermal Binding Machine
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.The invention relates to a device for producing bound documents with representative covers, whereby texts, magazines, constructive representations, image collections, contracts, offers, advertising material (catalogs) in an appealing form, in small to medium series can be brought onto the market.
Die Anwendung ist für den privaten und gewerblichen Gebrauch vorgesehen, insbesondere für Arbeiten in Architektur-, Ingenieur-und Konstruktionsbüros, sowie in Steuerberatungsund Rechtsanwaltskanzleien und auch Schulen, Verwaltungen oder Werbeagenturen.The application is intended for private and commercial use, in particular for work in architecture, engineering and construction offices, as well as in tax consulting 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.There are already sophisticated technical solutions for binding loose, described or otherwise printed sheets in relatively small editions, which are more or less described and have so far been used.
Anhand der nachfolgend genannten technischen Lösungen soll prinzipiell der Stand der Technik dokumentiert werden.In principle, the state of the art is to be documented using the technical solutions mentioned below.
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 specification CH 677053 A5 presents a device for binding sheets by heating, an aluminum rail with recesses for heating elements being arranged in the interior of an octagonal housing. The device allows two folders to be bound at the same time, and the switching duration of the PTC heating elements can be regulated in time using built-in electronics. On the one hand, the compact design has the advantage of being easy to use, but on the other hand the disadvantage that the cycle times between heating and cooling are high and energy is "wasted". Additional ventilation slots in the bottom of the housing are proposed to reduce this time disadvantage.
In der europäischen Patentanmeldung EP 0 489 336 AI 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 European patent application EP 0 489 336 AI, a table device for binding a bundle of papers along a common edge is proposed. The technical process of making bound products combines the steps of laminating and binding. Pre-made covers cannot be used with loose sheets. The introduction of the heating energy is ensured via several blocks of heat-conducting material, in particular consisting of aluminum, the cooling process not being technically supported. Transport using several pairs of rollers can be seen as complex and mechanically sensitive.
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. Gemäß der europäischen Patentanmeldung EP 0 841 192 AI 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.The US patent application 5 829 938 also presents a heatable table device with which a given paper stack is “gripped” by means of an L-shaped binding tape wetted with adhesive after insertion and electrical heating and then by manual swiveling in the sense of “folding” short pressure is applied in the area to be glued. There are no special measures for the effective use of heating energy once it has been introduced and its shielding for the purpose of short-term cooling, although subsequent “packaging” in a cover must also take place separately. According to the European patent application EP 0 841 192 AI there is now an electrically heated table device with multiple receptacles of defined width for binding sheets or sheets, whereby the optimal time of the time by heating the covers equipped with the sheets / sheets, which in turn have an adhesive insert "Ejection" can be initiated by switchable magnetic contacts. If the heating element is still warm at this point, the cover may be "rejected" if the heating time is not set correctly.
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 derived from the prior art must now be overcome, the object of the invention being to improve the energetic conditions of known binding devices, to enable binding of bindings made of metallic or non-metallic materials to be made equally possible and also with a technique which optimally controls the binding time enable different formats of sheets or sheets to be bound, with no restrictions on usable binders.
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, the basic inventive ideas being set out in claim 1 and the further embodiment being carried out in claims 2 to 11.
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.The central element of the binding device is an elongated and inherently stable ceramic surface that can be quickly heated and cooled, and on the underside of which a heating element is attached. The inductive sensors, which are arranged in pairs or several, which are located under the ceramic surface, trigger the heating of the ceramic surface when inserting a binder, up to the optimal softening point of the adhesive material deposited in the back of a metallic cover, whereby thermal sensors distributed over the heating surface of this ceramic surface monitor Act. This prevents incorrect bindings by means of precisely specified temperatures and control times, which can be regulated electrically, and prevents warping of the book cover due to overheating from the outset.
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.In addition to the use of covers with a rigid metallic insert, folders can also be produced that are designed in a different way, namely manufacture from plastic materials, cardboard or from laminated materials.
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. 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.For this purpose, in addition to the aforementioned inductive sensors, there are one or more mechanically loadable sensors, which can be introduced in the width of the heating surface, and by lowering a crossbar that is spring-loaded on both sides, the heating contact can be initiated or activated by actuating an optical or microswitch (button). can be switched off at any time by means of the measurement using the existing thermal sensors. Another sensor that partially emerges upwards in a transverse gap in the ceramic heating surface, for example in the form of a wire helix, is in electrical contact with a contact wire / resistance wire when subjected to load, which means that measured in terms of the width of an arbitrarily obtained cover or its weight with the ones to be bound Scrolling the electrical resistance can be detected microelectronically and supports the heating and switching-off process of the thermal sensors by determining the required heating time. In an additional embodiment ensuring the function, the inside of the sensor has an arranged hose along with an adjustment facility for setting a defined pressure, the load introduced by inserting a cover being in operative connection with a pressure-sensing sensor and / or switch. The latter then triggers the start of the heating of the ceramic heating surface. The position of the sensor can be provided in the center of the ceramic heating surface or at the end of the same, a stop forming the end of the ceramic heating surface in the latter.

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.The ceramic heating surface 1 is located in a thermal binding device on the upper side of the housing 5. In order to support the sheets 14 to be bound together with the cover 13, retaining brackets 23 are provided in pairs above the lateral ceramic heating surface 1. The ceramic heating surface 1 on the underside of which a heating element is integrated or a Peletier element is attached also has on its underside one or more inductive sensors 3 and thermosensors 2 which on the one hand trigger the heating process and on the other hand after the optimum melting of the binding adhesive and sinking in of the Sheets 14 in the existing cover 13 switch off the heating process.
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.Due to the different materials of the binder, reaching the melting temperature of the adhesive is influenced. Different materials require different binding temperatures and different binding times. To detect bindings / binders without a metal insert, microswitches or optical sensors, which can be acted upon via a crosspiece 15, are alternatively used.
Unabhängig von dem Bindemappenwerkstoff ermittelt der Drucksensor 22 aus dem Gewicht einer Mappe die dazugehörige Bindebreite und die dafür nötige Bindezeit bei vorgegebener Bindetemperatur.Regardless of the binder material, the pressure sensor 22 determines from the weight of a folder the associated binding width and the binding time required for this at a predetermined binding temperature.
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.With the arrangement of a sensor consisting of the elements flexible hose 6, switch 7 and wire helix 8, in the area of the ceramic heating surface 1, the binding folder width is recognized and the heating time is precisely regulated.
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.The wire coil 8 also serves the same purpose when the contact wire / resistance wire 10 comes into contact as a result of loading by the binder. The changed resistance in the contact wire / resistance wire 10 is used as the width of the binder for heating control. Appropriately, with the wire coil 8 in a lateral position, the stop 9 is located next to it. The flexible hose 6 with a piston 11 and the adjusting screw 12 for adjusting the output signal is also arranged under the wire coil 8.
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. Along the ceramic heating surface 1, a / or a row of piezo elements can be arranged on its underside, which promote the sinking of the sheets 14 into a cover 13 by oscillation and vibration during the melting of the binding adhesive. For rapid cooling of bound covers, one or more motor fans 4 are positioned below, to the side of the ceramic heating surface 1, the air currents generated only reaching the cover / covers 13 by means of a pivotable, motor-operated cover plate 19 and the residual heating energy of the ceramic heating surface 1 is not attacked if possible , The drive for the cover plate 19, i.e. the motor is marked with the position symbol 20. For this purpose, the ceramic heating surface 1 can additionally be pivoted off by means of a motor 21. The cooling process is advantageously designed to be able to be forced in time in the vicinity of the covers 13 by switchable Peltier elements. It can be provided that a transverse web 18 serves as a mounting surface for the binding material, in the event that the ceramic heating surface 1 is designed to be laterally displaceable for the purpose of cooling.
