Definitions
- the invention relates to a wide-belt sanding device for machining preferably panel-shaped workpieces, and to a method.
- the operator of the wide-belt sander is usually responsible for handling the workpiece, which can lead to the tool of the wide-belt sander not being evenly worn over the time the tool is in use.
- the engagement time is the time that the tool was already engaged. Uneven wear of the tool can prevent a consistent surface quality of the workpieces to be machined.
- partial (one-sided) wear of a tool can further accelerate the wear of the tool and, in the worst case, lead to damage to the tool and possibly to the workpiece being machined at the moment.
- wide-belt sanders as a specific example of a wide-belt sander, it is generally known that the individual workpieces to be machined often do not occupy the full width of the wide-belt sander. This means that when such a workpiece is machined, only a certain part of the abrasive (abrasive belt) is used and thus worn out, with the remaining part of the abrasive being unused. This leads to the need for the operator to distribute the workpieces to be processed over the entire width of the wide belt sander and over the entire engagement time of the abrasive (abrasive belt) in such a way that the abrasive is worn almost evenly.
- the DE 199 26 946 A1 which relates to a device for pneumatic position control of a workpiece in relation to a predetermined workpiece arrangement in a workpiece holder, an LED display that uses color coding of the fields to indicate whether the workpiece is correctly placed in the workpiece holder or not.

- the DE 100 41 925 A1 a method and an apparatus for grinding a workpiece with a rotating abrasive.
- the workpiece is fixed on a workpiece carrier and can be fed by a feed movement. Deviating from the direction of the feed movement, the workpiece carrier is set in an oscillating movement, resulting in a superimposed engagement movement.
- the changing direction of engagement of the abrasive, which is designed as an abrasive belt, on the workpiece leads to a significant improvement in the surface finish.
- a wide belt sanding device according to claim 1 and a method according to claim 11.
- Preferred developments of the invention are specified in the dependent claims.
- Features of the dependent device and method claims may apply to the independent claims, respectively.

- Step three checks whether wear status data is already available. That is, whether a workpiece W has already been placed in the wide belt sander and machined and therefore the tool WZ has already been partially worn out. If yes, continue with step 4. If there is no wear condition data, go to step 4a.
- method step four the present state of wear of the tool WZ is displayed to the operator by means of the light signal display device 10, which gives the operator the opportunity to optimally insert the workpiece W in the wide belt sander 2, so that the tool WZ is used evenly over the entire intervention time and is therefore worn will.
- method step four it is also possible to indicate an advantageous insertion position EPv of the workpiece W to the operator.
- the light signal display device 10 indicates to the operator 10 that there is no wear status data.
- the tool WZ is usually a new tool WZ for which no state of wear has yet been determined.
- this is signaled by a solid green light signal indicator, which means that there is no wear on the tool WZ.
- step 5 a current state of wear is determined.
- the state of wear is a summation of individual wear of the tool WZ, which is determined when a workpiece W is machined.
- the wear is determined here based on the recorded length dimensions X, Y and the recorded insertion position EP as well as existing processing parameters. Based on the length dimensions X, Y and the recorded insertion position EP, it can be determined which specific area of the tool WZ is affected by the machining that has been carried out stressed and thus worn out. Furthermore, based on the existing machining parameters, such as machining time, machining forces, grinding time, contact pressure, etc., the respective load or wear of the tool WZ can be determined. All in all, it can be determined specifically which area of the tool WZ is worn to what extent.
- a separate light display device for each unit in a wide belt sanding machine 2 with several units, such as in a wide belt sanding machine with four units.
- the four units can be, for example, two calibration rollers and two grinding belts (pre-grinding and fine grinding). This creates the possibility of displaying to the operator a determined degree of wear and an advantageous insertion position EPv for each individual unit.
- the degree of wear of all aggregates can first be displayed individually to an operator at the same time. If the operating mode is now switched on and/or a workpiece is inserted which is to be processed by three units, for example, the operator can be shown total wear and an advantageous insertion position EPv, taking into account the degrees of wear of all three units. For this purpose, the degrees of wear of the three units are offset against each other and a total value is formed.
- step six the determined current state of wear of the tool WZ of the wide belt sanding machine 2 is stored in a database so that the next time a new workpiece W is machined, it can be accessed.
- the method for operating a wide belt sanding machine 2 ends with step six and returns to the starting position (step 1).
Description
Die Erfindung betrifft eine Breitbandschleifvorrichtung zur Bearbeitung von bevorzugt plattenförmigen Werkstücken, sowie ein Verfahren.The invention relates to a wide-belt sanding device for machining preferably panel-shaped workpieces, and to a method.
Im Bereich der Breitbandschleifmaschinen, insbesondere bei Breitbandschleifmaschinen die im Handwerksbereich genutzt werden, obliegt meist vollständig das Werkstückhandling dem Bediener der Breitbandschleifmaschine, was dazu führen kann, dass das Werkzeug der Breitbandschleifmaschine über die Eingriffszeit des Werkzeugs nicht gleichmäßig abgenutzt wird. Hierbei ist unter Eingriffszeit die Zeit zu verstehen, die das Werkzeug bereits im Eingriff war. Eine ungleichmäßige Abnutzung des Werkzeugs kann einer gleichbleibenden Oberflächenqualität der zu bearbeitenden Werkstücke entgegenstehen.In the field of wide-belt sanders, especially in the case of wide-belt sanders used in the trade sector, the operator of the wide-belt sander is usually responsible for handling the workpiece, which can lead to the tool of the wide-belt sander not being evenly worn over the time the tool is in use. Here, the engagement time is the time that the tool was already engaged. Uneven wear of the tool can prevent a consistent surface quality of the workpieces to be machined.
Ferner kann eine partielle (einseitige) Abnutzung eines Werkzeugs die Abnutzung des Werkzeugs noch beschleunigen und im schlimmsten Fall zu einer Beschädigung des Werkzeugs und gegebenenfalls des in dem Moment bearbeitenden Werkstücks führen.Furthermore, partial (one-sided) wear of a tool can further accelerate the wear of the tool and, in the worst case, lead to damage to the tool and possibly to the workpiece being machined at the moment.
So ist es zum Beispiel bei Breitbandschleifmaschinen als ein konkretes Beispiel einer Breitbandschleifmaschine allgemein bekannt, dass die einzelnen zu bearbeitenden Werkstücke oft nicht die vollständige Breite der Breitbandschleifmaschine belegen. Dies führt dazu, dass bei einer Bearbeitung eines derartigen Werkstücks nur ein gewisser Teil des Schleifmittels (Schleifbands) genutzt und somit abgenutzt wird, wobei der restliche Teil des Schleifmittels unbenutzt ist. Dies führt zu der Notwendigkeit, dass der Bediener über die vollständige Breite der Breitbandschleifmaschine und über die komplette Eingriffszeit des Schleifmittels (Schleifbands) die zu bearbeitenden Werkstücke so verteilt, dass das Schleifmittel annährend gleichmäßig abgenutzt wird.For example, in the case of wide-belt sanders, as a specific example of a wide-belt sander, it is generally known that the individual workpieces to be machined often do not occupy the full width of the wide-belt sander. This means that when such a workpiece is machined, only a certain part of the abrasive (abrasive belt) is used and thus worn out, with the remaining part of the abrasive being unused. This leads to the need for the operator to distribute the workpieces to be processed over the entire width of the wide belt sander and over the entire engagement time of the abrasive (abrasive belt) in such a way that the abrasive is worn almost evenly.

Die Aufgabe wird gelöst durch eine Breitbandschleifvorrichtung nach Anspruch 1 sowie ein Verfahren nach Anspruch 11. Bevorzugte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Merkmale der abhängigen Vorrichtungs- und Verfahrensansprüche können jeweils bei den unabhängigen Ansprüchen Anwendung finden. Beispielsweise kann eine Steuereinrichtung der Breitbandschleifvorrichtung eingerichtet oder ausgelegt sein, bestimmte Verfahrensschritte auszuführen.The object is achieved by a wide belt sanding device according to claim 1 and a method according to claim 11. Preferred developments of the invention are specified in the dependent claims. Features of the dependent device and method claims may apply to the independent claims, respectively. For example, a control device of the wide belt sanding device can be set up or designed to carry out specific method steps.
Einer der Kerngedanken der vorliegenden Erfindung ist es, mittels einer Lichtsignalanzeigevorrichtung einer Bedienperson der Breitbandschleifvorrichtung visuell einen Abnutzungszustand eines Werkzeugs der Breitbandschleifvorrichtung und/oder eine vorteilhafte Einlegeposition des zu bearbeitenden Werkstücks in der Breitbandschleifvorrichtung anzuzeigen.One of the core ideas of the present invention is to use a light signal display device to visually indicate to an operator of the wide belt sander the state of wear of a tool of the wide belt sander and/or an advantageous insertion position of the workpiece to be machined in the wide belt sander.
Mittels der vorgeschlagenen Lichtsignalanzeigevorrichtung kann somit einer Bedienperson der Breitbandschleifvorrichtung auf einfache und sichere Weise stets der aktuelle Abnutzungszustand eines Werkzeugs und/oder eine vorteilhafte Einlegeposition eines mittels der Breitbandschleifvorrichtung zu bearbeitenden Werkstücks angezeigt werden. Hierdurch kann der Bedienperson ein Mittel zur Verfügung gestellt werden, welches es der Bedienperson ermöglicht, über die Eingriffszeit des Werkzeugs dieses annährend gleichmäßig abzunutzen, was zu einer längeren Lebensdauer des Werkzeugs sowie einer gleichbleibenden und hohen Oberflächenqualität des bearbeitenden Werkstücks beiträgt.Using the proposed light signal display device, the current state of wear of a tool and/or an advantageous insertion position of a workpiece to be machined using the wide-belt sanding device can therefore be displayed to an operator of the wide-belt sanding device in a simple and reliable manner. As a result, the operator can be provided with a means which enables the operator to wear the tool almost uniformly over the time it is in use, which contributes to a longer service life of the tool and a constant and high surface quality of the workpiece being machined.
Gemäß einem Aspekt der vorliegenden Erfindung weist die Breitbandschleifmaschine, insbesondere Breitbandschleifmaschine zur Bearbeitung von bevorzugt plattenförmigen Werkstücken, die bevorzugt zumindest abschnittsweise aus Holz, Holzwerkstoff und/oder Kunststoff bestehen, eine Steuereinrichtung und mindestens eine Lichtsignalanzeigevorrichtung auf, die an der Breitbandschleifmaschine derart eine Information anzeigt, dass die durch die Lichtsignalanzeigevorrichtung angezeigte Information für eine Bedienperson sichtbar bzw. wahrnehmbar ist, wobei die Steuereinrichtung eingerichtet ist, über die Eingriffszeit mindestens eines Werkzeugs der Breitbandschleifmaschine den aktuellen Abnutzungszustand des mindestens einen Werkzeugs der Breitbandschleifmaschine basierend auf einer Aufsummierung von ermittelten Abnutzungen des Werkzeugs zu ermitteln, wobei die Abnutzung des Werkzeugs basierend auf erfassten Längenabmessungen der bearbeiteten Werkstücke, einer erfassten Einlegeposition der jeweiligen Werkstücke und vorliegenden Bearbeitungsparametern ermittelt wird. Mittels der Lichtsignalanzeigevorrichtung kann der Bedienperson als die Information der Abnutzungszustand des mindestens einen Werkzeugs der Breitbandschleifmaschine und/oder eine vorteilhafte Einlegeposition des zu bearbeitenden Werkstücks in der Breitbandschleifmaschine visuell angezeigt werden.According to one aspect of the present invention, the wide-belt sanding machine, in particular wide-belt sanding machine for processing preferably panel-shaped workpieces, which preferably consist at least in sections of wood, derived timber product and/or plastic, has a control device and at least one light signal display device which displays information on the broad-band sander in such a way that that the information displayed by the light signal display device can be seen or perceived by an operator, with the control device being set up to determine the current state of wear of the at least one tool of the wide belt sander via the intervention time of at least one tool of the wide belt sander based on a summation of the determined wear of the tool , The wear of the tool based on detected length dimensions of the machined workpieces, a detected insertion position of the respec gene workpieces and existing processing parameters is determined. The wear status of the at least one tool of the wide belt sander and/or an advantageous insertion position of the workpiece to be machined in the wide belt sander can be visually displayed to the operator by means of the light signal display device.
Auf diese Weise wird eine Lichtsignalanzeigevorrichtung bereitgestellt, mit der bei einer Breitbandschleifmaschine auf einfache und sichere Weise dem Bediener der Abnutzungszustand des Schleifbands bzw. eine vorteilhafte Einlegeposition des zu bearbeitenden Werkstücks visuell angezeigt werden kann. Dies ist insbesondere bei Breitbandschleifmaschinen vorteilhaft, da wie oben bereits ausgeführt, bei Breitbandschleifmaschinen die im Handwerksbereich genutzt werden, das Teilehandling meist vollständig dem Bediener der Maschine obliegt, wodurch es erforderlich ist, dass der Bediener über die vollständige Breite der Breitbandschleifmaschine und über die komplette Eingriffszeit des Schleifbands die zu bearbeitenden Teile gleichmäßig verteilt, um das Schleifband gleichmäßig abzunutzen.In this way, a light signal display device is provided with which, in a wide belt sanding machine, the state of wear of the sanding belt or an advantageous insertion position of the workpiece to be machined can be visually displayed to the operator in a simple and reliable manner. This is particularly advantageous in the case of wide-belt sanders, since, as already explained above, the part handling in wide-belt sanders used in the trade sector mostly entirely the responsibility of the operator of the machine, which requires the operator to evenly distribute the parts to be machined over the full width of the wide belt sander and over the entire engagement time of the sanding belt in order to wear the sanding belt evenly.
Hierbei kann den Bediener die erfindungsgemäße Lichtsignalanzeigevorrichtung unterstützen, da sie dem Bediener stets den aktuellen Abnutzungszustand des Schleifbands und/oder die vorteilhafte Einlegeposition des momentan zu bearbeitenden Werkstücks auf einfache und sichere Weise visuell anzeigen kann.The light signal display device according to the invention can support the operator here, since it can always visually indicate to the operator the current state of wear of the grinding belt and/or the advantageous insertion position of the workpiece to be machined in a simple and reliable manner.
Hiermit ist es möglich, die Abnutzung des Schleifbands über die ganze Breite der Breitbandschleifmaschine gleichmäßig zu verteilen und damit die Eingriffszeit des Schleifbands zu erhöhen und eine gleichbleibende Oberflächenqualität der zu bearbeitenden Werkstücke zu gewährleisten.This makes it possible to evenly distribute the wear on the sanding belt over the entire width of the wide-belt sanding machine, thereby increasing the sanding belt's engagement time and ensuring a consistent surface quality of the workpieces to be machined.
Bevorzugt umfasst die Breitbandschleifmaschine eine Fördereinrichtung, insbesondere einen Riemen-, Ketten- oder Bandförderer, die eingerichtet ist, das Werkstück zum Bearbeitungswerkzeug zu bewegen und ggf. ferner aus der Breitbandschleifmaschine heraus zu fördern.The wide-belt sanding machine preferably includes a conveyor device, in particular a belt, chain or belt conveyor, which is set up to move the workpiece to the machining tool and, if necessary, also to convey it out of the wide-belt sander.
Bevorzugt ist die Lichtanzeigevorrichtung an einem Einlegebereich der Breitbandschleifmaschine vorgesehen, an welchem das zu bearbeitende Werkstück in die Breitbandschleifmaschine einlegbar und/oder mittels einer Fördereinrichtung zum Werkzeug bewegbar ist. Bei dem Einlegebereich handelt es sich in der Regel um eine Werkstückaufnahme, in welche das Werkstück eingelegt werden kann und an der eine Fördereinrichtung zum Bewegen des Werkstücks angeordnet werden kann. Bevorzugt ist die Lichtsignalanzeigevorrichtung in vertikaler Richtung oberhalb des Einlegebereichs angeordnet. Es besteht jedoch auch die Möglichkeit, die Information an dem Einlegebereich, insbesondere vertikal oberhalb des Einlegebereichs, anzuzeigen.The light display device is preferably provided on an insertion area of the wide belt sander, where the workpiece to be machined can be inserted into the wide belt sander and/or can be moved to the tool by means of a conveyor device. The insertion area is usually a workpiece holder into which the workpiece can be inserted and on which a conveyor device for moving the workpiece can be arranged. The light signal display device is preferably arranged in the vertical direction above the loading area. However, there is also the possibility of displaying the information in the loading area, in particular vertically above the loading area.
Somit ist es möglich, dem Bediener der Breitbandschleifmaschine direkt vor Ort, d.h., direkt an der Stelle, an der der Bediener das zu bearbeitende Werkstück in die Breitbandschleifmaschine einlegen muss, die Information über den Abnutzungszustand des Werkzeugs und/oder die vorteilhafte Einlegeposition des aktuellen Werkstücks auf einfache und sichere Weise anzuzeigen.It is thus possible to provide the operator of the wide-belt sander with information about the state of wear of the tool and/or the advantageous insertion position of the current workpiece directly on site, i.e. directly at the point where the operator has to insert the workpiece to be machined into the wide-belt sander display in a simple and safe way.
Gemäß einer bevorzugten Ausführungsform wird ein Werkstück in einem Einlegebereich von einer Fördereinrichtung, wie einem Riemen-, Band- oder Kettenförderer aufgenommen und zu einem Werkzeug der Breitbandschleifmaschine bewegt.According to a preferred embodiment, a workpiece is picked up in an insertion area by a conveyor device, such as a belt, belt or chain conveyor, and is moved to a tool of the wide-belt sanding machine.
Des Weiteren kann die Lichtsignalanzeigevorrichtung in Form einer Anzeigeleiste ausgebildet sein, welche sich entlang des Einlegebereichs erstreckt, und diesen insbesondere vollständig abdeckt. Es besteht jedoch auch die Möglichkeit, die Information derart anzuzeigen bzw. zu projizieren, dass sie sich teilweise oder vollständig entlang des Einlegebereichs erstreckt. Hierbei ist unter Anzeigeleiste eine schmale längliche Anzeige zu verstehen, welche sich entlang des Einlegebereichs erstreckt. Da die Werkstücke in der Regel horizontal und ebenflächig in den Einlegebereich der Bearbeitungsmaschine eingelegt werden, bietet es sich an, die Anzeigeliste ebenfalls horizontal und insbesondere oberhalb des Einlegebereichs vorzusehen. Ferner ist es vorteilhaft, wenn die Anzeigeleiste sich durchgehend von einem Seitenbereich des Einlegebereichs bis zu einem anderen Seitenbereich des Einlegebereichs erstreckt, d.h., die Anzeigeleiste den Einlegebereich vollständig oder im Wesentlichen vollständig abdeckt. Die Lichtsignalanzeigevorrichtung kann auch durch mehrere Anzeigeleisten ausgebildet sein.Furthermore, the light signal display device can be designed in the form of a display strip, which extends along the insertion area and, in particular, completely covers it. However, there is also the possibility of displaying or projecting the information in such a way that it extends partially or completely along the loading area. In this context, a display bar is to be understood as meaning a narrow, elongated display that extends along the loading area. Since the workpieces are generally placed horizontally and flat in the loading area of the processing machine, it makes sense to also provide the display list horizontally and in particular above the loading area. Furthermore, it is advantageous if the display bar extends continuously from one side area of the insertion area to another side area of the insertion area, i.e. the display bar completely or essentially completely covers the insertion area. The light signal display device can also be formed by several display bars.
Gemäß einer weiteren Ausführungsform vorliegender Erfindung kann die Lichtsignalanzeigevorrichtung anhand unterschiedlicher Farben der Bedienperson den Abnutzungszustand des Werkzeugs und/oder die vorteilhafte Einlegeposition des zu bearbeitenden Werkstücks anzeigen. Die Anzeige erfolgt insbesondere anhand der Farben grün, gelb und rot, wobei grün für einen guten Zustand des Werkzeugs bzw. eine gute Einlegeposition, gelb für einen mittleren Zustand des Werkzeugs bzw. eine mittlere Einlegeposition und rot für einen schlechten Zustand des Werkzeugs bzw. eine schlechte Einlegeposition verwendet wird. Es ist auch möglich Farbverläufe zur besseren Visualisierung zu nutzen.According to a further embodiment of the present invention, the light signal display device can use different colors to indicate to the operator the state of wear of the tool and/or the advantageous insertion position of the workpiece to be machined. The display is in particular based on the colors green, yellow and red, with green for a good condition of the tool or a good insertion position, yellow for an average condition of the tool or an average insertion position and red for a poor condition of the tool or a bad insertion position is used. It is also possible to use color gradients for better visualization.
Des Weiteren weist die Steuereinrichtung bevorzugt eine Werkstückerfassungseinrichtung auf, mittels der Längenabmessungen des Werkstücks und eine Einlegeposition des Werkstücks im Einlegebereich der Breitbandschleifmaschine erfassbar sind, insbesondere bereits vor dem Einlegen in den Einlegebereich erfassbar sind. Bei den Längenabmessungen des zu bearbeitenden Werkstücks handelt es sich in der Regel um die Breite und die Länge des Werkstücks. Ferner ist unter der Einlegeposition die Position des Werkstücks zu verstehen, an die die Bedienperson der Breitbandschleifmaschine das Werkstück in den Einlegebereich eingelegt hat.Furthermore, the control device preferably has a workpiece detection device, by means of which the length dimensions of the workpiece and a loading position of the workpiece in the loading area of the wide belt sander can be detected, in particular can already be detected before the loading into the loading area. The length dimensions of the workpiece to be machined are usually the width and the length of the workpiece. Furthermore, the insertion position is to be understood as meaning the position of the workpiece at which the operator of the wide belt sander has inserted the workpiece in the insertion area.
Auf diese Weise ist es möglich dem Bediener der Breitbandschleifmaschine vor dem Einlegen des zu bearbeitenden Werkstücks in den Einlegebereich der Breitbandschleifmaschine die vorteilhafte Einlegeposition des aktuellen Werkstücks anzuzeigen. Was es dem Bediener ermöglicht, das aktuelle Werkstück sofort auf die vorteilhafte Einlegeposition in der Breitbandschleifmaschine zu platzieren, was ein unnötiges erneutes Platzieren oder Verschieben des Werkstücks obsolet macht.In this way, it is possible to show the operator of the wide-belt sander the advantageous insertion position of the current workpiece before the workpiece to be machined is inserted into the insertion area of the wide-belt sander. Which allows the operator to immediately place the current workpiece to the advantageous loading position in the wide belt sander, making unnecessary re-positioning or moving of the workpiece obsolete.
Ferner ist die Steuereinrichtung eingerichtet, über die Eingriffszeit des Werkzeugs den Abnutzungszustand des Werkzeugs zu ermitteln und anhand der Lichtsignalanzeigevorrichtung der Bedienperson anzuzeigen.Furthermore, the control device is set up to determine the state of wear of the tool via the intervention time of the tool and to display it to the operator using the light signal display device.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung ermittelt die Steuereinrichtung über die Eingriffszeit des Werkzeugs gesehen den Abnutzungszustand des Werkzeugs, wobei die Steuereinrichtung anhand der erfassten Längenabmessungen der bearbeiteten Werkstücke und deren jeweiligen Einlegeposition in der Breitbandschleifmaschine (Position im Einlegebereich) sowie den jeweiligen Bearbeitungsparametern, wie z.B. Bearbeitungsdauer, Bearbeitungskräfte, Schleifdauer, Anpresskraft usw., den Abnutzungszustand ermittelt. Dies bedeutet, dass die Steuereinheit anhand der genannten Parameter eine Abnutzung des Werkzeugs berechnet, wobei auf empirisch ermittelte Erfahrungswerte oder simulierte Werte zur Ermittlung der Abnutzung zurückgegriffen wird, und die jeweilig ermittelten Abnutzungen summiert werden, um einen aktuellen Abnutzungszustand zu ermitteln. Auf die Ermittlung des Abnutzungszustands wird später noch im Detail eingegangen.According to a further embodiment of the present invention, the control device determines the state of wear of the tool over the engagement time of the tool, the control device using the recorded length dimensions of the machined workpieces and their respective insertion position in the wide belt sander (position in the insertion area) and the respective processing parameters, such as e.g. Machining time, machining forces, grinding time, contact pressure etc. determines the state of wear. This means that the control unit uses the parameters mentioned to calculate wear on the tool, using empirically determined empirical values or simulated values to determine the wear, and the wear determined in each case are summed up in order to determine a current state of wear. The determination of the state of wear will be discussed in detail later.
Des Weiteren ist mittels der Steuereinrichtung und anhand des ermittelten Abnutzungszustands des Werkzeugs sowie anhand der erfassten Längenabmessungen des zu bearbeitenden Werkstücks die vorteilhafte Einlegeposition des zu bearbeitenden Werkstücks ermittelbar, welche anhand der Lichtsignalanzeigevorrichtung der Bedienperson anzeigbar ist.Furthermore, the advantageous insertion position of the workpiece to be machined can be determined by means of the control device and based on the determined state of wear of the tool and based on the recorded length dimensions of the workpiece to be machined, which can be displayed to the operator using the light signal display device.
Bevorzugt besteht auch die Möglichkeit, die Steuerung so einzurichten, dass die vorteilhafte Einlegeposition stochastisch oder chaotisch bestimmt wird. D.h., die Einlegeposition wird nicht basierend auf dem Abnutzungszustand des Werkzeugs ermittelt, sondern über die Eingriffszeit des Werkstücks stochastisch oder chaotisch über die Werkzeugfläche verteilt, sodass, statistisch gesehen, das Werkzeug gleichmäßig über die Eingriffszeit abgenutzt wird. Des Weiteren kann die Lichtsignalanzeigevorrichtung eine Inspektionsvorrichtung aufweisen, mittels der eine Oberflächenbeschaffenheit, wie z.B. eine Maserungsrichtung, des zu bearbeitenden Werkstücks ermittelbar ist, und entsprechend der ermittelten Oberflächenbeschaffenheit anhand der Lichtsignalanzeigevorrichtung der Bedienperson eine vorteilhafte Einlegeposition und/oder vorteilhafte Einlegeorientierung anzeigbar ist.There is preferably also the possibility of setting up the control in such a way that the advantageous insertion position is determined stochastically or chaotically. This means that the insertion position is not determined on the basis of the state of wear of the tool, but is distributed stochastically or chaotically over the machining time of the workpiece over the tool surface, so that, statistically speaking, the tool is worn evenly over the machining time. Furthermore, the light signal display device can have an inspection device, by means of which a surface condition, such as a grain direction, of the workpiece to be machined can be determined, and according to the determined surface condition, an advantageous loading position and/or advantageous loading orientation can be displayed to the operator using the light signal display device.
Bevorzugt kann die Lichtanzeigevorrichtung als eine Projektionseinheit ausgebildet werden, insbesondere in Form eines Projektors.The light display device can preferably be designed as a projection unit, in particular in the form of a projector.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung ist die Lichtanzeigevorrichtung anhand einer LED-Leiste, einer OLED-Leiste und der gleichen ausgebildet, wobei eine Auflösung, d.h., der Abstand zwischen einzelnen Anzeigeelementen oder Anzeigeabschnitten der Lichtanzeigevorrichtung oder der Einteilung der Anzeigeabschnitte am projizierten Bereich weniger als 5 cm, insbesondere weniger als 2 cm beträgt. Bevorzugt wird die Lichtanzeigevorrichtung anhand eines Bands mit beabstandeten LEDs ausgebildet, wobei die Auflösung dem Abstand zwischen den einzelnen LEDs (Anzeigeelementen) entspricht. Ferner weist die Lichtanzeigevorrichtung bevorzugt eine 24 Bit Auflösung auf, mit der Farbverläufe angezeigt werden können.According to another embodiment of the present invention, the light display device is made using an LED bar, an OLED bar, and the like formed, wherein a resolution, ie, the distance between individual display elements or display sections of the light display device or the division of the display sections in the projected area is less than 5 cm, in particular less than 2 cm. Preferably, the light display device is formed using a strip of spaced LEDs, with the resolution corresponding to the spacing between the individual LEDs (display elements). Furthermore, the light display device preferably has a 24-bit resolution with which color gradients can be displayed.
Ferner kann es sich bei dem zumindest einen Werkzeug (WZ) der Breitbandschleifmaschine um ein Schleifband, eine Schleifwalze, Polierwalze, eine Tellerbürste oder dergleichen handeln. Im Falle mehrerer Werkzeuge können diese eines der genannten Werkzeuge umfassen. Weiter bevorzugt werden im Falle mehrere Werkzeuge verschiedene der genannten Werkzeuge kombiniert, beispielsweise eine oder mehrere Kalibrierwalze(n), ein oder mehrere Schleifbänder, eine oder mehrere Polierwalzen, eine oder mehrere Tellerbürsten.Furthermore, the at least one tool (WZ) of the wide belt sander can be a sanding belt, a sanding roller, a polishing roller, a disc brush or the like. If there are several tools, they can include one of the tools mentioned. More preferably, if there are several tools, different ones of the tools mentioned are combined, for example one or more calibrating roller(s), one or more grinding belts, one or more polishing rollers, one or more disk brushes.
Des Weiteren betrifft die vorliegende Erfindung ein Verfahren zum Betreiben einer Breitbandschleifmaschine, insbesondere der oben beschriebenen Breitbandschleifmaschine, wobei das Verfahren umfasst: Erfassen von Längenabmessungen des zu bearbeitenden Werkstücks, Erfassen der Einlegeposition des zu bearbeitenden Werkstücks in einem Einlegebereich der Breitbandschleifmaschine, Ermitteln einer Abnutzung des Werkzeugs basierend auf den erfassten Längenabmessungen der erfassten Einlegeposition und vorliegenden Bearbeitungsparametern, wie beispielsweise Bearbeitungsdauer, Bearbeitungskräfte, Schleifdauer, oder Anpresskraft, Ermitteln des aktuellen Abnutzungszustands des Werkzeugs der Breitbandschleifmaschine über die Eingriffszeit des Werkzeugs basierend auf einer Aufsummierung von ermittelten Abnutzungen des Werkzeugs, Anzeigen des ermittelten Abnutzungszustands des Werkzeugs mittels einer Lichtsignalanzeigevorrichtung, und/oder Anzeigen einer vorteilhaften Einlegeposition des zu bearbeitenden Werkstücks in der Breitbandschleifmaschine mittels der Lichtsignalanzeigevorrichtung, wobei insbesondere die vorteilhafte Einlegeposition basierend auf dem ermittelten Abnutzungszustand des Werkzeugs oder stochastisch bzw. chaotisch ermittelt wird.Furthermore, the present invention relates to a method for operating a wide belt sander, in particular the wide belt sander described above, the method comprising: detecting length dimensions of the workpiece to be machined, detecting the insertion position of the workpiece to be machined in an insertion area of the wide belt sander, determining wear on the tool based on the recorded length dimensions of the recorded insertion position and available processing parameters, such as processing time, processing forces, grinding time, or contact pressure, determining the current state of wear of the tool of the wide belt grinding machine over the intervention time of the tool based on a summation of determined wear of the tool, displaying the determined state of wear of the tool by means of a light signal display device, and/or displays an advantageous insertion position of the to edit the workpiece in the wide-belt sanding machine by means of the light signal display device, with the advantageous insertion position being determined based on the determined state of wear of the tool or stochastically or chaotically.

Ferner kann mittels des Verfahrens der aktuelle Abnutzungszustand des Werkzeugs über die Eingriffszeit des Werkzeugs basierend auf einer Aufsummierung von ermittelten Abnutzungen des Werkzeugs ermittelt werden, wobei die jeweiligen Abnutzungen des Werkzeugs jeweils zu dem Zeitpunkt ermittelt wurden, zu dem ein neues Werkstück in den Einlegebereich der Breitbandschleifmaschine eingelegt wurde.The method can also be used to determine the current wear status of the tool via the intervention time of the tool based on a summation of the determined wear on the tool, with the respective wear on the tool being determined at the time when a new workpiece entered the loading area of the wide belt sander was inserted.

Die Verwendung einer Kamera bietet den Vorteil, dass falls gewünscht eine Oberflächenbeschaffenheit des Werkstücks W, wie z.B. eine Maserungsrichtung, erfasst werden kann. In diesem Fall bildet die Kamera auch ein Bestandteil einer Inspektionsvorrichtung 40. Es können durch die Werkstückerfassungseinrichtung noch weitere Informationen (Daten) vorab ermittelt werden, wie z.B. Werkstücktyp, Werkstücknummer und dergleichen.The use of a camera offers the advantage that, if desired, a surface condition of the workpiece W, such as a grain direction, can be recorded. In this case, the camera also forms part of an inspection device 40. Further information (data) can be determined in advance by the workpiece detection device, such as workpiece type, workpiece number and the like.
In Schritt eins des Verfahrens zum Betreiben einer Breitbandschleifmaschine 2 werden anhand der Werkstückerfassungseinrichtung 30 Längenabmessungen X, Y des Werkstücks W erfasst und der Steuereinrichtung 20 eingegeben.In step one of the method for operating a wide
In Verfahrensschritt zwei wird anhand von Sensoren in der Breitbandschleifmaschine 2, insbesondere in dem Einlegebereich 4 und/oder anhand der Werkstückerfassungseinrichtung 30 eine Einlegeposition EP des zu bearbeitenden Werkstücks erfasst.In method step two, an insertion position EP of the workpiece to be machined is detected using sensors in the
Mit Verfahrensschritt drei wird geprüft, ob bereits Abnutzungszustandsdaten vorliegen. D.h., ob bereits vorher ein Werkstück W in die Breitbandschleifmaschine eingelegt und bearbeitet wurde und daher das Werkzeug WZ bereits teilweise abgenutzt wurde. Falls ja, wird mit Schritt 4 fortgefahren. Falls keine Abnutzungszustandsdaten vorliegen wird mit Schritt 4a weiter gemacht.Method step three checks whether wear status data is already available. That is, whether a workpiece W has already been placed in the wide belt sander and machined and therefore the tool WZ has already been partially worn out. If yes, continue with
In Verfahrensschritt vier wird der Bedienperson mittels der Lichtsignalanzeigevorrichtung 10 der vorliegende Abnutzungszustand des Werkzeugs WZ angezeigt, was der Bedienperson die Möglichkeit verschafft, das Werkstück W in der Breitbandschleifmaschine 2 optimal einzulegen, so dass das Werkzeug WZ über die komplette Eingriffszeit gesehen gleichmäßig verwendet und somit verschlissen wird. Im Verfahrensschritt vier ist es auch möglich, der Bedienperson eine vorteilhafte Einlageposition EPv des Werkstücks W anzuzeigen.In method step four, the present state of wear of the tool WZ is displayed to the operator by means of the light signal display device 10, which gives the operator the opportunity to optimally insert the workpiece W in the
Im parallelen Verfahrensschritt 4a wird mittels der Lichtsignalanzeigevorrichtung 10 der Bedienperson 10 angezeigt, dass keine Abnutzungszustandsdaten vorliegen. D.h., dass es sich bei dem Werkzeug WZ in der Regel um ein neues Werkzeug WZ handelt, für welches noch kein Abnutzungszustand ermittelt wurde. Im Allgemeinen wird dies anhand einer vollständig grün aufleuchtenden Lichtsignalanzeigevorrichtung signalisiert, was bedeutet, dass kein Verschleiß an dem Werkzeug WZ vorliegt.In the parallel method step 4a, the light signal display device 10 indicates to the operator 10 that there is no wear status data. This means that the tool WZ is usually a new tool WZ for which no state of wear has yet been determined. Generally this is signaled by a solid green light signal indicator, which means that there is no wear on the tool WZ.
Nach den beiden alternativen Verfahrensschritten 4 und 4a folgt der Schritt 5, bei welchem ein aktueller Abnutzungszustand ermittelt wird. Bei dem Abnutzungszustand handelt es sich um eine Aufsummierung von einzelnen Abnutzungen des Werkzeugs WZ, welche jeweils bei der Bearbeitung eines Werkstücks W ermittelt werden. Die Abnutzung wird hierbei basierend auf den erfassten Längenabmessungen X, Y und der erfassten Einlegeposition EP sowie vorliegenden Bearbeitungsparametern ermittelt. Basierend auf den Längenabmessungen X, Y und der erfassten Einlegeposition EP kann ermittelt werden, welcher konkrete Bereich des Werkzeugs WZ durch die durchgeführte Bearbeitung beansprucht und somit abgenutzt wird. Ferner kann basierend auf den vorliegenden Bearbeitungsparametern, wie z.B. Bearbeitungsdauer, Bearbeitungskräfte, Schleifdauer, Anpresskraft, usw. die jeweilige Belastung bzw. Abnutzung des Werkzeugs WZ ermittelt werden. In Summe kann konkret ermittelt werden, welcher Bereich des Werkzeugs WZ wie stark abgenutzt wird.The two alternative method steps 4 and 4a are followed by
Hierbei ist es auch möglich, einen Gesamtverschleiß bei einer Maschine mit mehreren Aggregaten (mit unterschiedlichen Werkzeugen WZ) zu ermitteln. So besteht die Möglichkeit, dass bestimmte Schleifaggregate bei der Bearbeitung eines bestimmten Werkstücks W außer Eingriff gebracht werden, z.B. eine der nachfolgend genannten Schleifeinrichtungen: eine oder mehrere Kalibrierwalzen (Stahlwalze und gummierte Walze) und/oder ein Feinschleifaggregat (Querband und H-Aggregat). So wird über mehrere unterschiedliche Werkzeuge hinweg ein gemeinsamer Gesamtverschleiß ermittelt und entsprechend dem Bediener ein Gesamtabnutzungszustand und/oder eine vorteilhafte Einlegeposition EPv, die den Gesamtabnutzungszustand berücksichtigt, mittels der Lichtsignalanzeigevorrichtung 10 angezeigt.It is also possible to determine the total wear on a machine with several units (with different tools WZ). It is therefore possible that certain grinding units are disengaged when processing a specific workpiece W, e.g. one of the following grinding devices: one or more calibrating rollers (steel roller and rubber-coated roller) and/or a fine grinding unit (cross belt and H unit). A common total wear is determined across several different tools and a total wear state and/or an advantageous insertion position EPv, which takes into account the total wear state, is displayed to the operator by means of the light signal display device 10 .
Dabei ist es auch möglich, den Abnutzungsgrad einzelner Schleifaggregate separat anzuzeigen.It is also possible to display the degree of wear of individual grinding units separately.
Ferner ist es auch möglich, bei einer Breitbandschleifmaschine 2 mit mehreren Aggregaten, wie z.B. bei einer Breitbandschleifmaschine mit vier Aggregaten, für jedes Aggregat eine separate Lichtanzeigevorrichtung, insbesondere LED-Leiste vorzusehen. Bei den vier Aggregaten kann es sich z.B. um zwei Kalibrierwalzen und um zwei Schleifbänder (Vor- und Feinschleifen) handeln. Auf diese Weise ist die Möglichkeit geschaffen, dem Bediener für jedes einzelne Aggregat einen ermittelten Abnutzungsgrad und eine vorteilhafte Einlegeposition EPv anzuzeigen.Furthermore, it is also possible to provide a separate light display device, in particular an LED bar, for each unit in a wide
Beispielsweise kann einem Bediener zunächst gleichzeitig der Abnutzungsgrad aller Aggregate einzeln angezeigt werden. Wird nun der Betriebsmodus eingeschaltet und/oder ein Werkstück eingelegt, welches z.B. von drei Aggregaten bearbeitet werden soll, kann dem Bediener ein Gesamtverschleiß und eine vorteilhafte Einlegeposition EPv unter Berücksichtigung der Abnutzungsgrade aller drei Aggregate angezeigt werden. Hierzu werden die Abnutzungsgrade der drei Aggregate miteinander verrechnet und ein Gesamtwert gebildet.For example, the degree of wear of all aggregates can first be displayed individually to an operator at the same time. If the operating mode is now switched on and/or a workpiece is inserted which is to be processed by three units, for example, the operator can be shown total wear and an advantageous insertion position EPv, taking into account the degrees of wear of all three units. For this purpose, the degrees of wear of the three units are offset against each other and a total value is formed.
Es besteht aber auch die Möglichkeit, dem Bediener alle drei Abnutzungsgrade separat anzuzeigen und es dem Bediener zu überlassen, wo er letztendlich das Werkstück einlegt.However, there is also the option of showing the operator all three degrees of wear separately and leaving it up to the operator where to ultimately insert the workpiece.
Ferner ist es möglich, nur anhand einer Lichtanzeigevorrichtung die gleiche Funktion zu realisieren, in diesem Fall würden einzelne horizontale Zeilen der Lichtanzeigevorrichtung, insbesondere der LED-Leiste, die verschiedenen Abnutzungsgrade anzeigen.Furthermore, it is possible to implement the same function using just one light display device; in this case, individual horizontal lines of the light display device, in particular the LED strip, would display the different degrees of wear.
Als nächstes wird in Schritt sechs der ermittelte aktuelle Abnutzungszustand des Werkzeugs WZ der Breitbandschleifmaschine 2 in einer Datenbank abgespeichert, so dass bei einer nächsten Bearbeitung eines neuen Werkstücks W auf diesen zurückgegriffen werden kann.
