Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Prüfen und Aussortieren von Ziegeln, welche auf einem Förderband einzeln einer mit einer Meßvorrichtung verbundenen Prüfvorrichtung zugeführt werden, wobei jeder Ziegel durch eine die Prüfvorrichtung tragende Schwenkeinrichtung von dem Förderband abgenommen, über die Meßvorrichtung geprüft und entweder als Abfall abgeworfen oder auf ein anderes Förderband transportiert wird, nach DBP 34 04 640.The invention relates to a method and a device for testing and sorting bricks, which are individually fed on a conveyor belt to a test device connected to a measuring device, each brick being removed from the conveyor belt by a swiveling device carrying the test device, checked via the measuring device and either discarded as waste or transported on another conveyor belt, according to DBP 34 04 64 0 .

Der Gegenstand des Hauptpatentes ist so beschaffen, daß durch das erfindungsgemäße Verfahren bzw. die Vorrichtung die Möglichkeit besteht, die den Qualitätsanforderungen nicht entsprechenden Ziegel abzuwerfen. Die anderen, für gut befundenen Ziegel werden jedoch im einzelnen nicht bewertet, obwohl sich auch hier Qualitätsunterschiede ergeben.The subject of the main patent is such that the method and the device according to the invention make it possible to throw off the bricks that do not meet the quality requirements. However, the other bricks, which were found to be good, are not assessed in detail, although there are also differences in quality here.

Aufgabe der vorliegenden Erfindung ist es daher, den Gegenstand nach dem Hauptpatent so weiterzubilden, daß auch die den Qualitätsanforderungen entsprechenden Ziegel eine Prüfung und Sortierung erfahren.The object of the present invention is therefore to further develop the object according to the main patent so that the bricks corresponding to the quality requirements are also tested and sorted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß durch die Meßvorrichtung und die Prüfvorrichtung jeder verwertbare Ziegel einzeln auf Qualitätsunterschiede geprüft wird und daß die Entnahme der auf dem anderen Förderband abgelegten, geprüften Ziegel entsprechend den einzelnen Güteklassen erfolgt. Hierdurch ergibt sich der Vorteil, daß durch das erfindungsgemäße Verfahren automatisch die den Güteanforderungen entsprechenden Ziegel eine Klassifizierung erfahren, welche den geforderten Güteanforderungen entspricht.According to the invention, this object is achieved in that each usable brick is individually checked for quality differences by the measuring device and the testing device, and that the checked bricks deposited on the other conveyor belt are removed in accordance with the individual quality classes. This has the advantage that the method according to the invention automatically classifies the bricks corresponding to the quality requirements which correspond to the required quality requirements.

Bei der Vorrichtung zur Durchführung des Verfahrens, welche mit einer mit Taststiften und einer Übersetzungseinrichtung verbundenen, optisch wirkenden Meßvorrichtung ausgestattet ist, weist die Meßvorrichtung entsprechend der Güteklassen der zu prüfenden Ziegel mehrere, mit der Übersetzungseinrichtung zusammenwirkende Lichtschranken auf und ist mit einer Steuereinheit verbunden. Diese Steuereinheit kann hierbei mit dem Antrieb des abtransportierenden Förderbandes und/oder mit einer Anzeigeeinheit verbunden sein.In the device for carrying out the method, which is equipped with an optically acting measuring device connected to styli and a translation device, the measuring device has a plurality of light barriers which interact with the translation device and is connected to a control unit in accordance with the quality classes of the bricks to be tested. This control unit can be connected to the drive of the conveying conveyor belt and / or to a display unit.

Eine andere Möglichkeit zur Durchführung des erfindungsgemässen Verfahrens besteht darin, daß die Vorrichtung mit einer Weiche im Endbereich des die geprüften Ziegel abtransportierenden Förderbandes verbunden ist. Hierbei können dem Förderband unter Zwischenschaltung der Weiche zwei weitere Förderbänder nachgeschaltet sein, wobei die drei Förderbänder und die dazwischengeschaltete Weiche vorteilhafterweise in einer im wesentlichen gemeinsamen horizontalen Ebene liegen.Another possibility for carrying out the method according to the invention is that the device is connected to a switch in the end region of the conveyor belt that transports the tested tiles. In this case, the conveyor belt can be followed by two further conveyor belts, with the three conveyor belts and the interposed switch advantageously lying in a substantially common horizontal plane.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. In der Zeichnung zeigen:

  • Fig. 1 eine schematische Ansicht der Vorrichtung zum Prüfen und Aussortieren von Ziegeln;
  • Fig. 2 bis 4 die Meßeinrichtung in einzelnen Meßpositionen;
  • Fig. 5 eine weitere Ausführungsform der Vorrichtung zum Prüfen und Aussortieren von Ziegeln.
The invention is described below with reference to exemplary embodiments shown in the drawing. The drawing shows:
  • Figure 1 is a schematic view of the device for checking and sorting bricks.
  • 2 to 4 the measuring device in individual measuring positions;
  • Fig. 5 shows another embodiment of the device for checking and sorting bricks.

In Fig. 1 ist schematisch eine Vorrichtung zum Prüfen und Aussortieren von Ziegeln gemäß DBP 34 04 640 dargestellt. Hierbei finden zwei Förderbänder 1 und 2 Anwendung, wobei zwischen diesen beiden Förderbändern 1 und 2 eine Abfördervorrichtung 4 angeordnet ist. Zwischen den Förderbändern 1 und 2 befindet sich eine Prüfvorrichtung 3, welche auf einer Schwenkeinrichtung 6 angeordnet ist. Diese Schwenkeinrichtung 6 ist als Doppelschwinge ausgebildet mit den beiden schwingenden Armen 7 und 8 und einem Koppelteil 9. Dieses Koppelteil 9 und die Schwingen 7 und 8 sind durch nicht näher bezeichnete Gelenke miteinander verbunden; die Schwingen 7 und 8 sind über nicht näher bezeichnete Gelenke gelenkig am Boden angebracht.In Fig. 1, a device for checking and sorting bricks according to DBP 34 04 640 is shown schematically. Here, two conveyor belts 1 and 2 are used, a conveyor device 4 being arranged between these two conveyor belts 1 and 2. Between the conveyor belts 1 and 2 there is a test device 3 which is arranged on a swivel device 6. This swiveling device 6 is designed as a double rocker arm with the two swinging arms 7 and 8 and a coupling part 9. This coupling part 9 and the rockers 7 and 8 are connected to one another by joints which are not described in more detail; the wings 7 and 8 are articulated on the floor via joints not specified.

Die Prüfvorrichtung 3 besitzt Anlagestifte 14 sowie Taststifte 16. Wie aus Fig. 1 ersichtlich, wird ein Ziegel 5, beispielsweise ein Biberschwanzziegel, auf dem Förderband 1 in Pfeilrichtung bewegt und bei der linken Stellung der Schwenkeinrichtung 6 von der Prüfvorrichtung 3 erfaßt.The test device 3 has contact pins 14 and feeler pins 16. As can be seen from FIG. 1, a brick 5, for example a plain tile, is moved on the conveyor belt 1 in the direction of the arrow and is detected by the test device 3 when the swivel device 6 is in the left position.

Nunmehr schwenkt infolge der Bewegung der Doppelschwingen 7 und 8 die Prüfvorrichtung 3 über ihren mittleren Bereich nach rechts zu dem Förderband 2. Während dieser Bewegung erfolgt eine Prüfung des betreffenden Ziegels auf Ebenflächigkeit und Verdrehung. Genügt dieser Ziegel den Qualitätsanforderungen der Prüfvorrichtung 3 nicht, so wird dieser Ziegel 5' in der Mittelstellung der Schwenkeinrichtung 6 abgeworfen und gelangt auf die Abfördervorrichtung 4, welche den Abfallziegel abtransportiert.Now, as a result of the movement of the double rockers 7 and 8, the test device 3 pivots over its central region to the right toward the conveyor belt 2. During this movement, the tile in question is checked for flatness and twist. If this brick does not meet the quality requirements of the testing device 3, then this brick 5 'is thrown off in the middle position of the swivel device 6 and reaches the removal device 4, which transports the waste brick away.

Entspricht der betreffende Ziegel 5" den Qualitätsanforderungen, so wird er in der rechten Lage der Schwenkvorrichtung 6 auf das Förderband 2 abgelegt und weitertransportiert.If the relevant brick 5 "corresponds to the quality requirements, it is placed in the right position of the swivel device 6 on the conveyor belt 2 and transported on.

Während der Bewegung der Schwenkeinrichtung 6 von der linken zur rechten Stellung werden auch diejenigen Ziegel qualitätsmäßig erfaßt, welche den Qualitätsnormen entsprechen. Die einzelnen, entsprechend den Qualitätsnormen aufgeschlüsselten Ziegel werden über eine elektrische Leitung 70 in einer Steuereinheit 80 erfaßt, wobei durch diese Erfassung das Abförderband 2 beispielsweise taktweise gesteuert wird und eine Anzeige in einem nicht näher dargestellten Bereich dann erfolgt, wenn beispielsweise ein Ziegel zweiter Wahl vorliegt. Dieser Ziegel zweiter Wahl kann durch eine nicht näher dargestellte Vorrichtung von dem Förderband 2 entnommen werden. Die den Qualitätsanforderungen als Ziegel erster Wahl entsprechenden Ziegel werden auf dem Förderband 2 zu einer nicht näher dargestellten Verpackungsvorrichtung transportiert und dort entsprechend verpackt und weiterbefördert.During the movement of the swiveling device 6 from the left to the right position, those bricks which meet the quality standards are also recorded in terms of quality. The individual bricks, which are broken down according to the quality standards, are recorded via an electrical line 70 in a control unit 80, the conveyor belt 2 being controlled, for example, cyclically by this recording and being displayed in an area not shown in more detail if, for example, a second choice brick is present . This brick of second choice can be removed from the conveyor belt 2 by a device, not shown. The bricks corresponding to the quality requirements as the brick of first choice are transported on the conveyor belt 2 to a packaging device (not shown in more detail), where they are packed and transported accordingly.

Durch die Steuereinheit 80 besteht also die Möglichkeit, Ziegel erster und zweiter Wahl qualitätsmäßig zu erfassen und im Bereich des taktweise laufenden Förderbandes 2 durch entsprechende Vorrichtungen die Ziegel erster und zweiter Wahl voneinander zu trennen.By means of the control unit 80 there is therefore the possibility of detecting the quality of the first and second choice bricks and of separating the bricks of the first and second choice from one another in the area of the cyclically running conveyor belt 2.

In Fig. 2 ist ein in Fig. 1 schematisch dargestellter Taststift 16 der Prüfvorrichtung 3 näher bezeichnet. Dieser Taststift 16 der Prüfvorrichtung 3 bildet ein Teil einer Meßvorrichtung 17 und ist in einem Gehäuse 35 der Prüfvorrichtung 3 gelagert. Oberhalb des Taststiftes 16 befindet sich in einem Drehpunkt 26 ein drehbar gelagerter, dreiarmiger Hebel 18 mit den Armen 20, 21 und 22. Der Arm 20 wird hierbei federbeaufschlagt, der Arm 21 steht mit dem oberen Teil des Taststiftes 16 in Verbindung, der Arm 22 arbeitet mit zwei Lichtquellen 25 und 50 zusammen.A stylus 16 of the test device 3, which is shown schematically in FIG. 1, is designated in more detail in FIG. 2. This stylus 16 of the test device 3 forms part of a measuring device 17 and is mounted in a housing 35 of the test device 3. Above the stylus 16 there is a pivoted, three-armed lever 18 with the arms 20, 21 and 22 at a pivot point 26. The arm 20 is spring-loaded, the arm 21 is connected to the upper part of the stylus 16, the arm 22 works with two light sources 25 and 50.

Befindet sich nach Fig. 2 die als dreiarmiger Hebel 18 ausgebildete Meßvorrichtung 17 bei guter Qualität des zu messenden Ziegels im Bereich der ersten Wahl, so sind die beiden Lichtstrahlen der Lichtquellen 25 und 50 durch die beiden Hebel 22 und 23 abgedeckt, so daß über die in Fig.1 dargestellte elektrische Leitung 70 ein entsprechendes Signal an Die Steuereinheit 80 abgegeben wird.2 is the three-armed lever 18 measuring device 17 with good quality of the brick to be measured in the area of first choice, the two light beams of the light sources 25 and 50 are covered by the two levers 22 and 23, so that the An electrical signal 70 shown in FIG. 1 is sent to the control unit 80.

Der Taststift 16 wird über die Feder 19 und den dreiarmigen Hebel, welcher um den Drehpunkt 26 schwenkt, entsprechend beaufschlagt. Weiterhin weist der Taststift 16 einen Bund 40 auf.The stylus 16 is acted upon accordingly via the spring 19 and the three-armed lever, which pivots about the pivot point 26. Furthermore, the stylus 16 has a collar 40.

Nach Fig. 3 liegt innerhalb der Qualitätsanforderung ein Ziegel 5" zweiter Wahl vor. Entsprechend ist nur noch die Lichtquelle 50 durch die beiden Hebel 22 und 23 bedeckt, wobei die Feder 19 den dreiarmigen Hebel 18 auf den Taststift 16 drückt. Das Ergebnis der Messung dieses Ziegels zweiter Wahl wird über die in Fig. 1 dargestellte elektrische Leitung 70 wiederum der Steuereinheit 80 mitgeteilt, so daß dieser Ziegel zweiter Wahl erfaßt wird. Durch die Steuereinheit 80 wird im Bereich des Abförderbandes 2 dann eine entsprechende, nicht näher dargestellte Abhub- oder Schiebevorrichtung betätigt, wodurch der Ziegel zweiter Wahl von dem Förderband 2 abgenommen werden kann.3 there is a brick 5 "of the second choice within the quality requirement. Accordingly, only the light source 50 is covered by the two levers 22 and 23, the spring 19 pressing the three-armed lever 18 onto the stylus 16. The result of the measurement This brick of second choice is in turn communicated to the control unit 80 via the electrical line 70 shown in Fig. 1 so that this brick of second choice is detected by the control unit 80 in the area of the conveyor belt 2 then a corresponding lifting or not shown Slider actuated, whereby the second choice brick can be removed from the conveyor belt 2.

Nach Fig. 4 liegt ein Ziegel 5' vor, welcher in keiner Weise den Qualitätsanforderungen entspricht. Entsprechend liegt der Taststift 16 in seiner untersten Lage, wobei diese Bewegung, welche durch die Feder 19 ausgelöst wird, durch den Bund 40 begrenzt ist, welcher seinerseits am Gehäuse 35 anliegt. In dieser Stellung gibt der dreiarmige Hebel 18 die beiden Lichtschranken 25 und 50 vollkommen frei, so daß in der in Fig. 1 dargestellten mittleren Position der den Qualitätsanforderungen nicht entsprechende Ziegel 5' auf das Förderband abgeworfen wird.4 there is a brick 5 'which in no way meets the quality requirements. Correspondingly, the stylus 16 lies in its lowermost position, this movement, which is triggered by the spring 19, being limited by the collar 40, which in turn rests on the housing 35. In this position, the three-armed lever 18 releases the two light barriers 25 and 50 completely, so that in the middle position shown in FIG. 1, the brick 5 'which does not meet the quality requirements is dropped onto the conveyor belt.

Die Halterung der Ziegel 5 an der Prüfvorrichtung 3 erfolgt durch einen im Hauptpatent beschriebenen, hier nicht näher dargestellten Saugkopf, welcher durch die Prüfvorrichtung 3 gesteuert wird und entsprechend die Ziegel in der funktionsrichtigen Lage freigibt.The bricks 5 are held on the test device 3 by a suction head described in the main patent, not shown here, which is controlled by the test device 3 and accordingly releases the bricks in the functional position.

In Fig. 5 ist eine andere Ausführungsmöglichkeit der Vorrichtung dargestellt. Hier befindet sich am Ende des Förderbandes 2 eine Weiche 60, welche mit zwei Förderbändern 61 und 62 zusammenwirkt. Vorteilhafterweise liegen hierbei die Förderbänder 2 sowie 61 und 62 und die Weiche 60 in einer im wesentlichen gleichen horizontalen Ebene; zur Verdeutlichung der Funktion wurden lediglich in Fig. 5 die Förderbänder 61 und 62 in verschiedenen horizontalen Ebenen angeordnet.Another possible embodiment of the device is shown in FIG. Here is at the end of the funding bandes 2 a switch 60 which interacts with two conveyor belts 61 and 62. Advantageously, the conveyor belts 2 and 61 and 62 and the switch 60 lie in an essentially identical horizontal plane; to illustrate the function, the conveyor belts 61 and 62 were only arranged in different horizontal planes in FIG. 5.

Wird nun ein Ziegel erster Wahl ermittelt, so bleibt die hinter dem Förderband 2 als Förderband ausgebildete Weiche 60 in der in Fig. 5 dargestellten Lage, wodurch der Ziegel 5" erster Wahl über die Weiche 60 zu dem Förderband 61 transportiert und später in nicht näher dargestellter Weise verpackt und abtransportiert wird.If a brick of the first choice is now determined, the switch 60 which is designed as a conveyor belt behind the conveyor belt 2 remains in the position shown in FIG. 5, as a result of which the brick 5 "of the first choice is transported via the switch 60 to the conveyor belt 61 and later not in closer detail is packaged and transported as shown.

Ergibt die Prüfung der Prüfvorrichtung 3, daß innerhalb der Qualitätsgrenzen ein Ziegel zweiter Wahl vorliegt, so wird über die elektrische Leitung 70 durch die Prüfvorrichtung 3 die als Förderband ausgebildete Weiche 60 verschwenkt, wodurch der Ziegel 5" zweiter Wahl auf das Förderband 62 gelangt und von hier entsprechend weiterbefördert wird.If the test of the test device 3 reveals that a brick of second choice is present within the quality limits, then the switch 60 designed as a conveyor belt is pivoted via the electrical line 70 through the test device 3, whereby the brick 5 "of the second choice reaches the conveyor belt 62 and from is transported here accordingly.

Zwischen der Prüfvorrichtung 3 und der Weiche 60 besteht also eine Wirkverbindung, wodurch die Weiche entsprechend dem Prüfergebnis der den Qualitätsanforderungen entsprechenden Ziegel 5" bzw. 5''' entsprechend bewegt wird.There is therefore an operative connection between the test device 3 and the switch 60, as a result of which the switch is moved in accordance with the test result of the bricks 5 ″ or 5 ″ ″ corresponding to the quality requirements.

Durch die Erfindung wird damit bewirkt, daß auch die den Qualitätsanforderungen entsprechenden Ziegel nach Güteklassen I und II automatisch sortiert und abtransportiert werden.The effect of the invention is that the bricks corresponding to quality requirements are automatically sorted and transported according to quality classes I and II.
