Abstract

The invention relates to a method for bonding grinding material, in particular, endless grinding belts or grinding belt segments onto a grinding element, preferably a grinding disk, or the like. Used endless grinding belts can be removed from the grinding elements only under great difficulties. However, such operations must be performed at regular intervals, as soon as the service life of the endless grinding belt has been exceeded. In particular, the removal of adhesive residues from the grinding element is a tedious task and the use of aggressive solvents is disadvantageous for the adhesive. In order to eliminate these disadvantages, the invention provides that a separating layer which is made of an unstable material with respect to solvents, is applied on at least one of the two engaging faces of an endless grinding belt and the grinding element before applying the adhesive layer. Preferably, the separating layer is mounted on the engagement face of the grinding element. As a material for the separating layer, an adhering agent, for example, a plastic resin is particularly suitable. The endless grinding belt can be bonded onto this adhering agent. Since the material used for the separating layer is easily dissolvable with a mild solvent, a used endless grinding belt can be easily removed from the grinding element, without any remaining adhesive residues.

Description

Die Erfindung betrifft ein Verfahren zum Kleben von Schleifmaterial, insbesondere Schleifband bzw. Schleifband-Abschnitten auf einen Schleifkörper, vorzugsweise eine Schleifscheibe o. dgl.The invention relates to a method for gluing abrasive material, in particular abrasive belt or abrasive belt sections on an abrasive body, preferably a grinding wheel or the like.

Insbesondere in der Möbelindustrie, wo sowohl glatte als auch profilierte Oberflächen zu schleifen sind, werden Schleifkörper eingesetzt, deren am zu bearbeitenden Werkstück angreifende Oberflächen, meistens die Umfangsfläche, mit Schleifband bedeckt bzw. ummantelt werden. Das Schleifband wird mit der Leinen- oder Papierseite direkt auf die zugeordnete Außenfläche des Schleifkörpers aufgeklebt, z. B. mittels eines Kontaktklebers.In the furniture industry in particular, where both smooth and profiled surfaces are to be ground, grinding bodies are used whose surfaces which attack the workpiece to be machined, usually the peripheral surface, are covered or coated with sanding belt. The sanding belt is glued with the linen or paper side directly onto the assigned outer surface of the grinding body, e.g. B. by means of a contact adhesive.

Statt eines Schleifbandes können auf die Schleifkörper auch Abschnitte aus einem Schleifband geklebt werden, insbesondere dann, wenn die damit zu beklebende Oberfläche des Schleifkörpers profiliert ist, um z. B. eine profilierte Holzoberfläche bearbeiten zu können.Instead of an abrasive belt, sections from an abrasive belt can also be glued to the grinding wheel, in particular if the surface of the grinding wheel to be glued to it is profiled in order, for. B. to be able to edit a profiled wooden surface.

Sobald die Standzeit des Schleifmaterials bzw. Schleifbandes erschöpft ist, muß das verbrauchte Schleifband vom Schleifkörper entfernt werden und ist durch ein neues Schleifband zu ersetzen.As soon as the service life of the abrasive material or abrasive belt is exhausted, the used abrasive belt must be removed from the abrasive body and replaced with a new abrasive belt.

Die EP-A 5 161 gibt an, einen Kontaktkleber auf dem Schleifkörper anzubringen. In das dadurch auf dem Schleifkörper gebildete Klebstoffbett wird das Schleifband gedrückt. Das Schleifband hat an seiner mit dem Klebstoffbett in Berührung kommenden Anlagefläche eine Trennschicht, die mit dem Klebstoff nur eine verminderte Haftung eingeht. Dadurch soll das Abziehen des abgenutzten Schleifbandes erleichtert werden.EP-A 5 161 specifies that a contact adhesive should be applied to the grinding wheel. The grinding belt is pressed into the bed of adhesive thus formed on the grinding wheel. The abrasive belt has a separating layer on its contact surface that comes into contact with the adhesive bed, which only has reduced adhesion with the adhesive. This should make it easier to remove the worn sanding belt.

Das bis dahin inzwischen ausgehärtete Klebstoffbett bleibt jedoch auch nach dem Abziehen des abgenutzten Schleifbandes am Außenumfang eines Schleifkörpers erhalten. Gerade bei profilierten Schleifkörpern, die eine in ihren Außenumfang eingearbeitete Kontur aufweisen, um damit Profile schleifen zu können, muß aber, bevor ein neues Schleifband aufgebracht wird, auch die Klebstoffschicht entfernt werden.However, the adhesive bed that has cured by then remains intact even after the worn abrasive belt has been removed from the outer circumference of an abrasive wheel. Especially in the case of profiled grinding bodies which have a contour machined into their outer circumference in order to be able to grind profiles, the adhesive layer must also be removed before a new grinding belt is applied.

Die Schleifkörper werden z. B. in ein Lösungsmittel getaucht, welches die Klebstoffschicht auflösen soll. Dabei gelingt das vollständige Auflösen der Klebstoffschicht gewöhnlich nicht. Die Klebstoffschicht wird lediglich angelöst. Die an dem Schleifkörper noch haftenden Klebstoffreste können dann nur durch harte mechanische Oberflächenbearbeitung entfernt werden. Hierfür wird z. B. ein kräftiges Reiben mit Stahlwolle, auch unter Einsatz von zusätzlichem Lösungsmittel notwendig.The grinding wheels are z. B. immersed in a solvent which is to dissolve the adhesive layer. It is usually not possible to completely dissolve the adhesive layer. The adhesive layer is only dissolved. The adhesive residues still adhering to the grinding wheel can then only be removed by hard mechanical surface treatment. For this, z. B. vigorous rubbing with steel wool, also with the use of additional solvent necessary.

Häufig bestehen die Schleifkörper aus elastischem Material, wie Gummi oder Kork, und bei solchem Werkstoffen kann es vorkommen, daß in Bereichen, in denen der Klebstoff nicht vollständig gelöst ist, aus der Anlagefläche des Schleifkörpers Stücke herausgerissen werden, wodurch der Schleifkörper unbrauchbar wird.Frequently, the grinding wheels consist of elastic material, such as rubber or cork, and with such materials it can happen that in areas in which the adhesive is not completely dissolved, pieces are torn out of the contact surface of the grinding wheel, making the grinding wheel unusable.

Das bisher bekannte Verfahren zum Entfernen von verbrauchten Schleifbändern von den Schleifkörpern hat auch den Nachteil, daß verhältnismäßig aggressive Lösungsmittel benötigt werden, deren Verarbeitung unangenehm oder sogar gesundheitsschädlich ist. Durch ein aggressives Lösungsmittel kann auch der Werkstoff des Schleifkörpers angegriffen und zerstört werden. Insbesondere bei mit Profilkonturen versehenen Schleifkörpern kann durch das wiederholte ständige feste Abreiben von Klebstoffrückständen die vorbestimmte, in den Schleifkörper eingeschnittene Profilkontur verändert werden, so daß der Schleifkörper auch dadurch für das Bearbeiten von Profilen unbrauchbar wird.The previously known method for removing used grinding belts from the grinding wheels also has the disadvantage that relatively aggressive solvents are required, the processing of which is unpleasant or even harmful to health. The material of the grinding wheel can also be attacked and destroyed by an aggressive solvent. Particularly in the case of abrasive bodies provided with profile contours, the predetermined constant profile cut into the abrasive body can be changed by the repeated, constant rubbing off of adhesive residues, so that the abrasive body also becomes unusable for machining profiles.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Kleben von Schleifmaterial auf einen rotierenden Schleifkörper zu finden, das ein leichteres Ablösen eines verbrauchten Schleifbandes vom Schleifkörper ermöglicht.The invention has for its object to find a method for gluing abrasive material to a rotating grinding wheel, which enables easier removal of a used grinding belt from the grinding wheel.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst worden, daß vor dem Anbringen der Klebstofflage auf wenigstens eine der beiden gegenseitigen, miteinander zu verklebenden Anlageflächen von Schleifband und Schleifkörper eine Trennschicht aus gegen Alkohol, insbesondere Spiritus als Lösungsmittel unbeständigem Vinylharz oder Polyurethanharz oder einer Mischung aus Vinylharz und Polyurethanharz auf die Anlagefläche des Schleifkörpers aufgetragen wird.This object has been achieved according to the invention in that before the adhesive layer is applied to at least one of the two mutual contact surfaces of the abrasive belt and the abrasive body, a separating layer made of vinyl resin or polyurethane resin or a mixture of vinyl resin and polyurethane resin which is resistant to alcohol, in particular alcohol as a solvent is applied to the contact surface of the grinding wheel.

Die Trennschicht verhindert in vorteilhafter Weise den direkten Kontakt des Klebstoffs mit den zu verklebenden Anlageflächen. Um ein verbrauchtes Schleifband z. B. von einer Schleifscheibe zu entfernen, genügt demzufolge ein Auflösen der Trennschicht. Die Trennschicht weist mit Vorteil die Eigenschaft auf, daß sie in einem Alkohol, insbesondere Spiritus, als verhältnismäßig mildes Lösungsmittel leicht gelöst werden kann, wenn der Schleifkörper mit dem Schleifband in das Lösungsmittel eingetaucht wird. Somit ist es nicht mehr notwendig, aggressive Lösungsmittel zum Auflösen der Klebstoffschicht zu verwenden. Klebstoffrückstände können an den Anlageflächen auch nicht mehr haften bleiben, sobald die Trennschicht aufgelöst ist.The separating layer advantageously prevents direct contact of the adhesive with the contact surfaces to be bonded. To a used sanding belt z. B. to remove from a grinding wheel, it is therefore sufficient to dissolve the interface. The separating layer advantageously has the property that it can be easily dissolved in an alcohol, in particular alcohol, as a relatively mild solvent if the grinding wheel is immersed in the solvent with the grinding belt. It is therefore no longer necessary to use aggressive solvents to dissolve the adhesive layer. Adhesive residues can no longer stick to the contact surfaces as soon as the separating layer is dissolved.

Da die Trennschicht auf der Anlagefläche des Schleifkörpers aufgetragen wird, kann dann, wennn diese Trennschicht durch das Lösungsmittel aufgelöst wurde, das Schleifband mit den an seiner Anlagefläche haftenden Klebstoffresten zusammen entfernt werden.Since the separating layer is applied to the contact surface of the grinding body, when this separating layer has been dissolved by the solvent, the grinding belt with the adhesive residues adhering to its contact surface can be removed together.

Bei einer bevorzugten Ausführung ist vorgesehen, daß eine leicht lösbare Trennschicht auf der Anlagefläche des Schleifkörpers aufgetragen wird, und daß auf die Anlagefläche des Schleifbandes eine Trennschicht aus gegen das gleiche Lösungsmittel relativ beständigem Werkstoff aufgetragen wird.In a preferred embodiment it is provided that an easily releasable separating layer is applied to the contact surface of the grinding body and that a separating layer made of material which is relatively resistant to the same solvent is applied to the contact surface of the grinding belt.

Weil für die Trennschicht ein als Haftmittel wirkendes Vinylharz oder Polyurethanharz oder eine Mischung aus Vinylharz und Polyurethan verwendet wird, ergibt sich aus der Anordnung von Haftmitteln verschiedener Löslichkeit eine Verbindung zwischen Schleifkörper und Schleifband mit hoher Festigkeit.Because a vinyl resin or polyurethane resin or a mixture of vinyl resin and polyurethane acts as an adhesive for the separating layer is used, the arrangement of adhesives of different solubility results in a connection between the grinding body and the grinding belt with high strength.

Selbstverständlich können auch andere Haftmittel eingesetzt werden. Wichtig für das als Trennschicht einsetzbare Haftmittel sind lediglich dessen Eigenschaften. Es muß hochflexibel und temperaturbeständig sein sowie günstige Adhäsionseigenschaften aufweisen, um mit den Anlageflächen sowohl vom Schleifkörper als auch vom Schleifband feste Verbindungen eingehen zu können.Of course, other adhesives can also be used. Only the properties of the adhesive that can be used as a separating layer are important. It must be highly flexible, temperature-resistant and have good adhesive properties in order to be able to make firm connections with the contact surfaces of both the grinding wheel and the grinding belt.

Dies gilt auch für die Verbindungseigenschaften mit dem einzusetzenden Kleber, der vorzugsweise ein Kontaktkleber ist.This also applies to the connection properties with the adhesive to be used, which is preferably a contact adhesive.

Ferner sollte das als Trennschicht verwendbare Haftmittel nach dem Aufbringen verhältnismäßig schnell abtrocknen. Eine weitere wichtige Eigenschaft, die das als Trennschicht verwendete Haftmittel erfüllen sollte, ist sein Lösungsvermögen in einem Lösungsmittel, daß nicht gesundheitsschädlich, nicht aggressiv und unkompliziert in der Verarbeitung ist.Furthermore, the adhesive that can be used as a release layer should dry relatively quickly after application. Another important property that the adhesive used as a release layer should fulfill is its ability to dissolve in a solvent which is not harmful to health, is not aggressive and is uncomplicated to process.

Bei der Verwendung von Vinyl- oder Polyurethanharzen, die die vorgenannten Eigenschaften erfüllen, besteht außerdem noch die vorteilhafte Möglichkeit, die Lösungseigenschaften in dem zu verwendenden Lösungsmittel durch den Zusatz eines Härters zum Harz einzustellen. Daraus ergibt sich der bereits beschriebene Vorteil, daß auf der Leinenseite des Schleibandes bzw. einzelner Schleifband-Abschnitte ein Haftmittel aufgetragen werden kann, während das auf der Anlagefläche des Schleifkörpers befindliche Trennmittel keinen Härterzusatz aufweist und somit im Lösungsmittel leicht gelöst werden kann.When using vinyl or polyurethane resins that meet the aforementioned properties, there is also the advantageous possibility of adjusting the solution properties in the solvent to be used by adding a hardener to the resin. This results in the advantage already described that an adhesive can be applied to the linen side of the abrasive belt or individual abrasive belt sections, while the release agent located on the contact surface of the abrasive body has no hardener additive and can therefore be easily dissolved in the solvent.

Mögliche Haftgrundstücke können dann durch ein leichtes Abreiben vom Schleifkörper entfernt werden, ohne daß dieser beschädigt wird. Durch die Verwendung von unterschiedlichen Haftmitteln, eines leicht und eines schwerer lösbaren Haftmittels, wird eine relativ hohe Klebefestigkeit der Verbindung des Schleifbandes mit dem Schleifkörper erreicht.Possible adhesive properties can then be removed by rubbing them slightly off the grinding wheel without damaging it. The use of different adhesives, one that is easy to remove and one that is more difficult to remove, results in a relatively high adhesive strength of the connection of the abrasive belt to the abrasive body.

Selbstverständlich wäre auch ein Werkstoff für die erfindungsgemäße Trennschicht möglich, der sich in Wasser auflöst. Wasser hat jedoch den Nachteil, daß unter Umständen metallische Teile des Schleifkörpers durch Korrosion angegriffen werden können. Dies ist bei Spiritus nicht der Fall.Of course, a material for the separating layer according to the invention that dissolves in water would also be possible. However, water has the disadvantage that metallic parts of the grinding wheel can be attacked by corrosion. This is not the case with alcohol.

Die erfindungsgemäßen Maßnahmen haben den Vorteil, daß sie bei allen Schleifkörpern aus Kork, Gummi, Metall, Holz o. dgl. Werkstoffen eingesetzt werden können, die mit aufgeklebtem Schleifmaterial versehen werden. Um nach überschrittener Standzeit das Schleifmaterial auswechseln zu können, ist ein Anlösen des Klebstoffes nicht mehr notwendig. Nach Auflösen der Trennschicht läßt sich das Schleifband leicht von dem Schleifkörper lösen. Umständliches und aufwendiges Vorbereiten der Schleifkörper, bevor ein neues Schleifband aufgeklebt werden kann, entfällt, so daß die aufzuarbeitenden Schleifkörper in kürzester Zeit wieder zum Einsatz, z. B. in einer Schleifmaschine, gebracht werden können.The measures according to the invention have the advantage that they can be used with all abrasive bodies made of cork, rubber, metal, wood or the like. Materials that are provided with bonded abrasive material. In order to be able to replace the abrasive material after a longer service life, it is no longer necessary to loosen the adhesive. After the separation layer has been dissolved, the grinding belt can easily be detached from the grinding body. Laborious and time-consuming preparation of the grinding wheel before a new grinding belt can be glued on is not necessary, so that the grinding wheel to be refurbished can be used again in the shortest possible time, e.g. B. can be brought in a grinding machine.
