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 angrei - fende 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 Kontaktkle - bers.In the furniture industry in particular, where both smooth and profiled surfaces are to be ground, grinding bodies are used whose surfaces touching the workpiece to be machined, usually the peripheral surface, are covered or coated with sanding belt. The abrasive belt is glued with the linen or paper side directly onto the assigned outer surface of the abrasive body, e.g. using 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 is profiled, e.g. to be able to process 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.

Das Entfernen des verbrauchten Schleifbandes vom Schleifkörper ist eine mühsame und aufwendige Arbeit. Die Schleifkörper wer - den z.B. in ein Lösungsmittel getaucht, welches die Klebstoffschicht zwischen den Anlageflächen von Schleifkörper und Schleifband auflösen soll. Dabei gelingt das'vollständige Auflösen der Klebstoffschicht gewöhnlich nicht. Die Klebstoff - schicht wird lediglich angelöst. Beim Abreißen des verbrauchten Schleifbandes bleiben somit Klebstoffreste an dem Schleifkörper haften, die nur durch harte mechanische Oberflächenbearbeitung entfernt werden können. Hierfür wird z.B. ein kräf - tiges Reiben mit Stahlwolle, auch unter Einsatz von zusätzli - chem Lösungsmittel notwendig.Removing the used grinding belt from the grinding wheel is a tedious and time-consuming task. The grinding wheels are dipped in a solvent, for example, which is intended to dissolve the adhesive layer between the contact surfaces of the grinding wheel and grinding belt. It is usually not possible to completely dissolve the adhesive layer. The adhesive layer is only loosened. When the used grinding belt is torn off, adhesive residues remain on the grinding body and can only be removed by hard mechanical surface treatment. This requires, for example, vigorous rubbing with steel wool, also with the use of additional solvents.

Häufig bestehen die Schleifkörper aus elastischem Material, wie Gummioder Kork, und bei solchen Werkstoffen kann es vorkommen, daß beim Abreißen des verbrauchten Schleifbandes 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 are made of elastic material, such as rubber or cork, and with such materials it can happen that, when the used grinding belt is torn off in areas in which the adhesive is not completely dissolved, pieces are torn out of the contact surface of the grinding wheel, as a result of which the grinding wheel becomes unusable.

Das bisher eingesetzte Verfahren zum Entfernen von verbrauchten Schleifbändern von den Schleifkörpern hat auch den Nach - teil, 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 Kleberückständen die vorbestimmte, in den Schleifkörper eingeschnittene Profilkontur verändert werden, so daß der Schleifkörper auch dadurch für das Bearbeiten von Profilen unbrauchbar wird.The previously used method for removing used abrasive 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, eine 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 allows 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 Lösungsmittel unbeständigem Werkstoff aufgetragen wird.This object has been achieved in that Before applying the adhesive layer, a separating layer made of solvent-resistant material is applied to at least one of the two mutual contact surfaces of the abrasive belt and the abrasive body.

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 verhältnismäßig milden Lösungsmittel leicht gelöst werden kann, wenn der Schleifkörper mit dem Schleifband in ein Lösungsmittel eingetaucht wird. Somit ist es nicht mehr notwendig, aggressive Lösungsmittel zum Auflösen der Klebstoff - schicht 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. Around a used sanding belt e.g. To remove from a grinding wheel, it is sufficient to dissolve the interface. The separating layer advantageously has the property that it can be easily dissolved in a relatively mild solvent if the grinding body is immersed in a 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.

Vorzugsweise wird die Trennschicht auf der Anlagefläche des Schleifkörpers aufgetragen, so daß dann, wenn diese Trenn - schicht durch das Lösungsmittel aufgelöst wurde das Schleifband mit den an seiner Anlagefläche haftenden Klebstoffresten zusammen entfernt werden kann.The separating layer is preferably applied to the contact surface of the grinding body, so that 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.

Insbesondere dann, wenn als Trennschicht ein Haftmittel verwendet wird, ergibt sich aus der Anordnung von Haftmitteln verschiedener Löslichkeit eine Verbindung zwischen Schleifkörper und Schleifband mit hoher Festigkeit.In particular, if an adhesive is used as the separating layer, the arrangement of adhesives of different solubility results in a connection between the grinding body and the grinding belt with high strength.

Als Haftmittel ist z.B. die Verwendung eines Vinylharzes vorgesehen. Es kann auch ein Polyurethanharz eingesetzt werden. Selbstverständlich ist auch eine Mischung der beiden Harze möglich.For example, the use of a vinyl resin is preferred as the adhesive see. A polyurethane resin can also be used. A mixture of the two resins is of course also possible.

Die Verwendung eines Harzes als Haftmittel ist bevorzugt geeignet. Selbstverständlich können auch andere Haftmittel eingesetzt werden. Wichtig für das als Trennschicht einsetzbare Haftmittel sind lediglich dessen Eigenschaften. Es muß hoch - flexibel und temperaturbeständig sein sowie günstine Adhäsionseigenschaften aufweisen, um mit den Anlageflächen sowohl vom Schleifkörper als auch vom Schleifband feste Verbindungen eingehen zu können.The use of a resin as an adhesive is preferably suitable. 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 favorable adhesive properties in order to be able to make firm connections with the contact surfaces of both the grinding body 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 demAufbringen verhältnismäßig schnell abtrocknen. Eine weitere wichtige Eigenschaft, die das als Trennschicht verwendete Haftmittel erfüllen sollte, ist sein Lösungsvermögen in einem Lö - sungsmittel, 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 work with.

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 Schleifbandes bzw. einzelner Schleifband-Abschnitte ein Haftmittel aufgetragen werden kann, das durch den Zusatz eines Härters kaum noch angelöst wird, 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 sanding belt or individual sanding belt sections, which is hardly dissolved by the addition of a hardener, while the release agent located on the contact surface of the grinding body has no hardener additive and can be easily dissolved in the solvent.

Mögliche Haftgrundrückstände 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 Uerbindung des Schleifbandes mit dem Schleifkörper erreicht.Possible residues of adhesive can then be removed by a light Rubbing can be removed from the grinding wheel without damaging it. Through the use of different adhesives, an easily and a more difficult to remove adhesive, a relatively high adhesive strength of the connection of the grinding belt to the grinding body is achieved.

Bei Einsatz der bevorzugt verwendbaren Werkstoffe für die Trennschicht kann als Lösungsmittel Alkohol, insbesondere Spiritus, verwendet werden. 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.When using the preferred materials for the separating layer, alcohol, in particular alcohol, can be used as the solvent. 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 aufge - klebtem Schleifmaterial versehen werden. Um nach überschrittener Standzeit das Schleifmaterial auswechseln zu können, ist ein Anlösen des Klebstoffs nicht mehr notwendig. Nach Auflösen der Trennschicht läßt sich das Schleifband leicht von dem Schleifkörper lösen. Umständliches und aufwendiges Vor - bereiten 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 which 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 wheels before a new grinding belt can be glued on is not necessary, so that the grinding wheels to be refurbished can be used again in the shortest possible time, e.g. in a grinding machine.
