Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Prüfen und Aussortieren von Ziegeln, mit einem Förderband und einer oberhalb des Förderbandes angeordneten, mit Taststiften versehenen Prüfvorrichtung, welche über eine Meßvorrichtung und eine Steuereinheit mit einer Abwurfvorrichtung verbunden ist.The invention relates to a device for testing and sorting bricks, with a conveyor belt and a test device which is arranged above the conveyor belt and is provided with stylus pins and which is connected via a measuring device and a control unit to a discharge device.

Als Stand der Technik ist hierbei bereits eine Vorrichtung zur Kontrolle der Maß- und Formgenauigkeit, insbesondere plattenförmiger Gegenstände, bekannt (DE-A-2 434 603). Diese bekannte Vorrichtung ist so gestaltet, daß als Förderband zwei parallel laufende, keilartige Elemente vorgesehen sind. Auf diesen Riemenelementen liegt der zu prüfende Gegenstand. Sobald er sich im Bereich der Prüfvorrichtung befindet, dringt von unten eine Stützplatte durch die Zwischenräume zwischen die beiden Förderbänder und hebt den zu prüfenden Gegenstand gegen die Prüfvorrichtung. Nach Durchführung der Prüfung wird über eine Markierungsvorrichtung der Gegenstand optisch gekennzeichnet, ob er den Qualitätsanforderungen genügt oder als Abfallprodukt entfernt werden muß.A device for checking the dimensional and shape accuracy, in particular plate-shaped objects, is already known as prior art (DE-A-2 434 603). This known device is designed so that two parallel wedge-like elements are provided as the conveyor belt. The object to be tested lies on these belt elements. As soon as it is in the area of the test device, a support plate penetrates from below through the spaces between the two conveyor belts and lifts the object to be tested against the test device. After the test has been carried out, the object is visually marked by a marking device as to whether it meets the quality requirements or has to be removed as a waste product.

Es ergibt sich hierbei der Nachteil, daß die zu prüfenden Gegenstände nur mit Linienberührung auf den beiden Förderbändern liegen, wobei die Stützplatte die zu prüfenden Gegenstände gegen die Prüfvorrichtung anheben muß. Hieraus resultiert sowohl ein baulicher, als auch ein erheblicher zeitlicher Aufwand bei der Durchführung des Prüfverfahrens, wobei außerdem nachteiligerweise der zu prüfende Gegenstand angehoben und abgesenkt werden muß.This has the disadvantage that the objects to be tested only lie on the two conveyor belts with line contact, the support plate having to lift the objects to be tested against the test device. This results in a constructional as well as a considerable expenditure of time when carrying out the test method, the object to be tested also having to be raised and lowered disadvantageously.

Zum Stand der Technik zählt weiterhin eine Prüfvorrichtung zur Ermittlung, ob einzelne elektrische bzw. elektronische Komponenten auf einem Träger ordnungsgemäß angebracht sind (GB-A-1 248 841). Diese bekannte Vorrichtung ist nicht zum Messen und Prüfen von Ziegeln geeignet.The prior art also includes a test device for determining whether individual electrical or electronic components are properly attached to a carrier (GB-A-1 248 841). This known device is not suitable for measuring and testing bricks.

Darüber hinaus ist ein Automat zum Prüfen der Maßhaltigkeit von Werkstücken bekannt, welcher ebenfalls nicht in den Gattungsbereich der vorliegenden Erfindung fällt (DE-U-1 914 838). Auch eine Maschine zum Prüfen von Glasbehältern, welche zum bekannten Stand der Technik zählt, kann nicht zum Prüfen und Aussortieren von Ziegeln herangezogen werden (DEA-1 548 210). Weiterhin ist eine Vorrichtung bekannt, welche eine Anzahl von Kurvenscheiben einsetzt, um die einzelnen Elemente funktionsmäßig bei der Durchführung der Prüfung miteinander zu verbinden (GB-A-912 640).In addition, an automatic machine for checking the dimensional accuracy of workpieces is known, which likewise does not fall within the scope of the present invention (DE-U-1 914 838). Even a machine for checking glass containers, which is part of the known prior art, cannot be used for checking and sorting bricks (DEA-1 548 210). Furthermore, a device is known which uses a number of cams to functionally connect the individual elements to one another when the test is carried out (GB-A-912 640).

Bei der Beurteilung der Neuheit zählt zum Stand der Technik noch ein Verfahren und eine Vorrichtung zum Prüfen und Aussortieren von Ziegeln (EP-A1-153 575 Art. 54 (3) Dokument). Hierbei werden die zu prüfenden Ziegel von einem Transportband über eine Doppelschwinge auf eine Transportbahn überführt, wobei während dieses Überführungsvorganges die Qualitätsprüfung erfolgt.When assessing novelty, the prior art also includes a method and a device for checking and sorting bricks (EP-A1-153 575 Art. 54 (3) document). Here, the bricks to be tested are transferred from a conveyor belt to a conveyor belt via a double rocker, the quality check being carried out during this transfer process.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung gemäß der eingangs genannten Gattung zu schaffen, welche bei einfacherem Aufbau eine schnellere und wirkungsvollere Qualitätskontrolle durchführt.The invention has for its object to provide a device according to the type mentioned, which performs a quicker and more effective quality control with a simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Prüfvorrichtung gegenüber dem Förderband heb- und senkbar ausgebildet ist, daß die Taststifte der Prüfvorrichtung über eine Übersetzungseinrichtung die Meßvorrichtung steuern, daß die Übersetzungseinrichtung ein dreiarmiger Hebel ist, dessen einer Hebelarm die Meßvorrichtung steuert, dessen zweiter Hebelarm mit den oberen, dem Förderband abgewandten Enden der Taststifte in Verbindung steht und dessen dritter Hebelarm federbeaufschlagt ist, und daß das Förderband kontinuierlich bewegbar ist mit synchronem Mitlauf der Prüfvorrichtung über eine Teilstrecke. Es ergibt sich hierdurch der Vorteil eines zeitsparenden Prüfverfahrens, wobei der zu prüfende Gegenstand insofern eine schonende Behandlung erfährt, als er nicht von dem Förderband entfernt werden muß.This object is achieved in that the test device is designed to be raised and lowered relative to the conveyor belt, that the probe pins of the test device control the measuring device via a translation device, that the translation device is a three-armed lever, one lever arm of which controls the measuring device, the second lever arm communicates with the upper ends of the feeler pins facing away from the conveyor belt and the third lever arm of which is spring-loaded, and that the conveyor belt is continuously movable with synchronous tracking of the test device over a partial distance. This results in the advantage of a time-saving test method, the object to be tested being treated gently insofar as it does not have to be removed from the conveyor belt.

In weiterer Ausgestaltung der Erfindung kann die Meßvorrichtung mechanisch, elektrisch, elektronisch, hydraulisch oder pneumatisch ausgebildet sein. Weiterhin besteht erfindungsgemäß die Möglichkeit, daß die Abwurfvorrichtung eine Kolben-Zylinder-Einheit ist, deren Antriebsteil mit der Steuereinheit verbunden ist.In a further embodiment of the invention, the measuring device can be designed mechanically, electrically, electronically, hydraulically or pneumatically. Furthermore, according to the invention there is the possibility that the ejection device is a piston-cylinder unit, the drive part of which is connected to the control unit.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. In der Zeichnung zeigen :

  • Fig. 1 eine schematische Seitenansicht der erfindungsgemäßen Vorrichtung ;
  • Fig. 2 eine schematische Darstellung der Taststifte und der Meßvorrichtung.
The invention is described below with reference to an embodiment shown in the drawing. The drawing shows:
  • Fig. 1 is a schematic side view of the device according to the invention;
  • Fig. 2 is a schematic representation of the stylus and the measuring device.

In Fig. 1 ist eine Vorrichtung zum Prüfen und Aussortieren von Ziegeln 5 dargestellt. Hierbei findet ein Förderband 1 Anwendung, auf welchem in Abteilen die Ziegel 5 liegen. Das Förderband 1 bewegt sich in Pfeilrichtung, d. h. in der Zeichenebene von rechts nach links. Oberhalb des Förderbandes ist eine Prüfvorrichtung 2 angeordnet, welche stirnseitig mit Taststiften 3 versehen ist. Diese Prüfvorrichtung 2 kann in Pfeilrichtung nach unten gegen den zu prüfenden Ziegel bewegt werden.1 shows a device for checking and sorting bricks 5. Here, a conveyor belt 1 is used, on which the bricks 5 lie in compartments. The conveyor belt 1 moves in the direction of the arrow, i.e. H. in the drawing plane from right to left. A test device 2 is arranged above the conveyor belt and is provided on the end face with stylus pins 3. This test device 2 can be moved downward in the direction of the arrow against the brick to be tested.

Über eine Leitung 11 ist die mit einer nicht näher dargestellten Meßvorrichtung verbundene Prüfvorrichtung mit einer Steuereinheit 4 verbunden. Über eine Leitung 10 steht diese Steuereinheit mit einer Abwurfvorrichtung 6 in Verbindung. Diese Abwurfvorrichtung ist als Kolben-Zylinder-Einheit 7 ausgebildet.The test device, which is connected to a measuring device, not shown, is connected to a control unit 4 via a line 11. This control unit is connected to a discharge device 6 via a line 10. This ejection device is designed as a piston-cylinder unit 7.

Das Prüfungsverfahren läuft wie folgt ab : Befindet sich ein zu prüfender Ziegel unterhalb der Prüfvorrichtung 2, so stoppt das Förderband 1 und die Prüfvorrichtung 2 bewegt sich in Pfeilrichtung nach unten, bis die Taststifte 3 die Oberfläche des Ziegels 5 beaufschlagen und damit seine Ebenflächigkeit prüfen. Dieses Prüfungsergebnis wird durch die Meßvorrichtung ausgewertet und an die Steuereinheit 4 abgegeben. In der Steuereinheit 4 wird der Wert gespeichert. Handelt es sich bei dem zu prüfenden Ziegel um einen Abfallziegel 5', so gibt die Steuereinheit 4 über die Leitung 10- ein Signal an die Kolben-Zylinder-Einheit 7, so daß diese beim Vorliegen des Abfallziegels 5' in Tätigkeit tritt und den Ziegel seitlich von dem Förderband 1 abwirft. Das Förderband 1 braucht daher nicht durchbrochen ausgebildet zu sein.The test procedure is as follows: If there is a tile to be tested below the test device 2, the conveyor belt 1 stops and the test device 2 moves downwards in the direction of the arrow until the feeler pins 3 surface of the brick 5 and check its flatness. This test result is evaluated by the measuring device and output to the control unit 4. The value is stored in the control unit 4. If the brick to be tested is a waste brick 5 ', the control unit 4 gives a signal to the piston-cylinder unit 7 via the line 10-, so that it comes into operation when the waste brick 5' is present and the brick throws off the side of the conveyor belt 1. The conveyor belt 1 therefore does not need to be open.

Es besteht auch die Möglichkeit, daß das Förderband kontinuierlich läuft, wobei sich die Prüfvorrichtung 2 auf den zu prüfenden Ziegel absenkt und über eine Teilstrecke synchron mit dem Förderband 1 mitläuft.There is also the possibility that the conveyor belt runs continuously, the test device 2 descending onto the tile to be tested and running synchronously with the conveyor belt 1 over a partial distance.

In Fig. 2 ist die Wirkungsweise der Taststifte 3 näher dargestellt. Beim Absenken der Prüfvorrichtung 2 beaufschlagen die Taststifte die Oberfläche des zu prüfenden Ziegels 5. Die Taststifte sind hierbei im nicht näher dargestellten Gehäuse der Prüfvorrichtung 2 gelagert. Oberhalb des Taststiftes 3 befindet sich ein in einem Drehpunkt 16 drehbar gelagerter dreiarmiger Hebel 8 mit den Armen 9, 12 und 13. Der Arm 12 ist hierbei federbeaufschlagt, der Arm 13 steht mit dem oberen Teil des Taststiftes 3 in Verbindung, der Arm 9 arbeitet mit einer Lichtquelle 14 zusammen.In Fig. 2, the operation of the stylus 3 is shown in more detail. When the test device 2 is lowered, the feeler pins act on the surface of the brick 5 to be tested. The feeler pins are stored in the housing of the test device 2, which is not shown in detail. Above the stylus 3 there is a three-armed lever 8 with the arms 9, 12 and 13, which is rotatably mounted in a fulcrum 16. The arm 12 is spring-loaded, the arm 13 is connected to the upper part of the stylus 3, and the arm 9 works together with a light source 14.

Befindet sich der dreiarmige Hebel 8 bei guter Qualität des zu messenden Ziegels im Bereich des Lichtstrahles der Lichtquelle 14, so ragt der Hebelarm 9 in diesen Bereich des Lichtstrahles. Damit liegt ein qualitativ guter Ziegel vor und dieses Meßergebnis wird über die Leitung 11 der Steuereinheit 4 mitgeteilt, welche ihrerseits zu einem gegebenen Zeitpunkt nicht die Bewegung der Kolben-Zylinder-Einheit 7 ansteuert. Ist jedoch, wie in Fig. 2 dargestellt, ein qualitativ schlechter Ziegel 5' vorhanden, so senkt sich der Taststift 3 bis auf seinen Flansch 20 ab, wodurch der dreiarmige' Hebel 8 unter Wirkung der Feder 21 im Uhrzeigersinn bewegt wird und damit aus dem Bereich des Lichtstrahls der Lichtquelle 14 gelangt. Nunmehr steuert dieser Lichtstrahl eine nicht näher dargestellte Einheit, wodurch über die Leitung 11 die Steuereinheit 4 ein Signal erhält, welches ihrerseits über die Leitung 10 zu einem gegebenen Zeitpunkt die Kolben-Zylinder-Einheit 7 betätigt, so daß über diese bei Vorliegen des qualitativ schlechten Ziegels 5' dieser an der betreffenden Station abgeworfen wird.If the three-armed lever 8 is of good quality of the brick to be measured in the area of the light beam from the light source 14, then the lever arm 9 projects into this area of the light beam. This is a good quality brick and this measurement result is communicated via line 11 to control unit 4, which in turn does not control the movement of piston-cylinder unit 7 at a given time. However, as shown in Fig. 2, a poor quality brick 5 'is present, the stylus 3 lowers down to its flange 20, whereby the three-armed' lever 8 is moved clockwise under the action of the spring 21 and thus out of Area of the light beam from the light source 14 arrives. Now this light beam controls a unit, not shown, whereby the control unit 4 receives a signal via the line 11, which in turn actuates the piston-cylinder unit 7 via the line 10 at a given point in time, so that when the quality is poor, the latter Brick 5 'this is dropped at the station in question.

Um den Toleranzbereich T einstellen zu können, kann an dem Hebelarm 9 des dreiarmigen Hebels 8 über einen Drehpunkt 24 ein weiterer Hebel 23 angebracht sein. Die beiden Hebel 9 und 23 geben damit im oberen Bereich eine Toleranzzone ; innerhalb dieser Toleranzzone, d. h. dem Bereich T, entspricht die Ebenflächigkeit des zu prüfenden Ziegels den Qualitätsansprüchen. Hierbei ist es auch möglich, bei geänderten Qualitätsansprüchen den Hebel 23 um den Drehpunkt 24 enger oder weiter zu schwenken, und damit den Toleranzbereich T zu vergrößern oder zu verkleinern.In order to be able to set the tolerance range T, a further lever 23 can be attached to the lever arm 9 of the three-armed lever 8 via a pivot point 24. The two levers 9 and 23 thus give a tolerance zone in the upper area; within this tolerance zone, d. H. the area T, the flatness of the tile to be tested corresponds to the quality requirements. It is also possible here to pivot the lever 23 closer or farther about the pivot point 24 in the case of changed quality requirements, and thus to increase or decrease the tolerance range T.

Es ist auch möglich, daß in Umkehr der Konstruktion die Prüfvorrichtung 2 einen Abfallziegel 5' dann abwirft, wenn der Lichtstrahl der Lichtquelle 14 unterbrochen wird.It is also possible that, in reverse of the construction, the test device 2 sheds a waste brick 5 'when the light beam from the light source 14 is interrupted.

Die Meßvorrichtung kann hierbei mechanisch, elektrisch, elektronisch, hydraulisch oder pneumatisch ausgebildet sein und ist in jedem Fall in der Lage, der Steuereinheit 4 über die Leitung 11 den Steuerbefehl zu geben, bei qualitativ gutem Ziegel diesen auf dem Förderband 1 zu belassen, d. h. bei Vorliegen eines Abfallziegels 5' über die Kolben-Zylinder-Einheit 7 diesen von dem Förderband 1 abzuwerfen.The measuring device can be designed mechanically, electrically, electronically, hydraulically or pneumatically and is in any case able to give the control unit 4 the control command via the line 11, to leave it on the conveyor belt 1 if the brick is of good quality, i. H. if a waste brick 5 'is present, throw it away from the conveyor belt 1 via the piston-cylinder unit 7.

Durch dieses Prüf- und Aussortierverfahren ergibt sich eine schonende ßehandlung der zu prüfenden Ziegel bei einfachem, konstruktivem Aufbau der Vorrichtung und Zeitersparnis während des Prüfverfahrens.This test and sorting process results in a gentle treatment of the bricks to be tested with a simple, constructive structure of the device and saves time during the test process.
