Description

Halte- und Transportvorrichtung  Holding and transport device
Die Erfindung betrifft eine Halte- und Transportvorrichtung nach dem Oberbegriff des Anspruchs 1. Diese werden insbesondere in Fertigungslinien von Presshärtverfahren eingesetzt und transportieren Zwischenprodukte, die erhitzt sind, insbesondere austenitisiert wurden zwischen dem Ofenaustritt und einem Umformwerkzeug, in welches sie eingelegt werden. Bei den Zwischenprodukten handelt es sich insbesondere um Platinen aus Metallblech oder bereits teilweise vorgeformte Formbauteile sowie die nach der Umformung entstandenen Halbzeuge vor der Endbearbeitung. The invention relates to a holding and transporting device according to the preamble of claim 1. These are used in particular in production lines of Presshärtverfahren and transport intermediates that are heated, in particular were austenitized between the furnace outlet and a forming tool, in which they are inserted. The intermediate products are, in particular, sheet metal plates or already partially preformed molded components and the semi-finished products formed after the forming prior to finishing.
Es ist wünschenswert, Informationen besonders über die Platinenentnahmetempera- tur aus dem Ofen bis zum Einlegen in das Umformwerkzeug zu erhalten, um frühzeitig Prozessfehler aufzudecken sowie Ausschussquoten minimieren zu können. Dazu werden in der Praxis bereits vereinzelt optische Pyrometer oder Thermographieka- meras am Ofenaustritt und/oder in der Presse eingebaut, um die Temperaturen an diesen Orten zu erfassen. Nachteilig ist dabei jedoch, dass nur punktuelle Messungen an den betreffenden Orten und zu den Zeitpunkten, zu denen das Zwischenprodukt sich an diesen Orten befindet, möglich sind. Auch hängt die Messgenauigkeit sehr stark von dem Emissionsfaktor des Zwischenprodukts ab. Dieser ist aufgrund der Schichtausprägung von Platine zu Platine unterschiedlich in Abhängigkeit von der Ofentemperatur und der Ofenhaltezeit, so dass meist keine genauen Kenntnisse über den Emissionsfaktor vorliegen. Bei Werkstücken mit unterschiedlich temperierten Bereichen sind die Messabweichungen umso höher, da aufgrund der unterschiedlichen Temperaturprofile verschiedene Emissionsfaktoren an einer Platine It is desirable to obtain information in particular about the board removal temperature from the furnace until it is placed in the forming tool in order to be able to detect process errors at an early stage and to minimize scrap rates. In practice, optical pyrometers or thermographic cameras are already occasionally installed at the oven outlet and / or in the press in order to record the temperatures at these locations. The disadvantage here, however, is that only punctual measurements at the locations concerned and at the times at which the intermediate product is located at these locations are possible. Also, the measurement accuracy depends very much on the emission factor of the intermediate product. This is due to the Schichtausprägung from board to board different depending on the furnace temperature and the furnace holding time, so that there is usually no exact knowledge about the emission factor. For workpieces with differently tempered areas, the measurement deviations are all the higher because, due to the different temperature profiles, different emission factors on a circuit board
BESTÄTIGUNGSKOPIE vorherrschen, die nur mittels vorheriger Durchführung von Schleppmessungen ermittelt und dann mit dem optischen Temperaturerfassungssystem abgeglichen werden müssen. Dies ist sehr aufwendig. CONFIRMATION COPY prevail, which must be determined only by previously carrying out drag measurements and then adjusted with the optical temperature detection system. This is very expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte und/oder vereinfachte Temperaturmessung der Zwischenprodukte zu ermöglichen. Diese Aufgabe wird mittels einer Halte- und Transportvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. The invention is therefore based on the object to enable an improved and / or simplified temperature measurement of the intermediates. This object is achieved by means of a holding and transport device with the features of claim 1.
Durch die Integration von zumindest einem taktilen, d.h. berührend messenden Temperaturmesssensor in die Halte- und Transportvorrichtung, die das Zwischenprodukt insbesondere vom Ofen zur Warmumformung, beispielsweise zur Presshärtform transportiert, können während des gesamten Transports Temperaturdaten über das Zwischenprodukt aufgenommen werden, so dass man eine Aussage nicht nur über die Temperatur des Zwischenprodukts bei Verlassen des Ofens und/oder beim Einlegen in die Form, sondern auch in der Zwischenzeit erhält. Diese Daten sind durch die taktile Messung von dem Emissionsgrad des Werkstücks unabhängig und daher wesentlich präziser, ohne dass es einer Ermittlung des Emissionsgrades im Vorfeld bedarf. Um an verschiedenen Punkten des Werkstücks Temperaturdaten aufzunehmen oder eine Sicherheit durch doppelte Messung zu erhalten, können auch mehrere Temperaturmesssensoren vorgesehen werden. Wenn im Folgenden vereinfachend "ein" oder "der" Temperaturmesssensor erwähnt ist, sollen dabei stets auch Ausführungsformen mit mehreren Sensoren umfasst sein. By integrating at least one tactile, i. Contacting measuring temperature measuring sensor in the holding and transport device, which transports the intermediate product in particular from the furnace for hot forming, for example to Presshärtform can be recorded throughout the transport temperature data on the intermediate product, so that a statement not only on the temperature of the intermediate product when leaving of the furnace and / or when inserting into the mold, but also in the meantime receives. Due to the tactile measurement, these data are independent of the emissivity of the workpiece and therefore much more precise, without the need to determine the emissivity in advance. In order to record temperature data at various points of the workpiece or to obtain security by double measurement, it is also possible to provide several temperature measuring sensors. If a "temperature sensor" or "the" temperature measuring sensor is mentioned in the following for the sake of simplification, embodiments with multiple sensors should always be included.
Da die Halte- und Transportvorrichtung während des Transportes des Zwischenproduktes mit diesem stets mit mindestens einem Kontaktbereich in Berührung steht, ist der Einsatz eines taktilen Temperaturmesssensors immer möglich. Über die daraus generierten Informationen lässt sich eine effiziente Prozessüberwachung bzw. Prozesssteuerung aufbauen, die unabhängig von den Oberflächeneigenschaften der Platine bzw. des Werkstücks ist. Über einen taktilen Temperaturmesssensor lassen sich hohe Mess- und Wiederholungsgenauigkeiten mit Messabweichungen <=1 ,5% und kurze Ansprechzeiten von maximal 2 Sekunden erreichen. Besonders für Werkstücke mit verschiedenen Temperaturbereichen sind erfindungsgemäß ausgestattete Halte- und Transportvorrichtungen von großem Vorteil, da besonders für diese Bauteile über Temperaturüberwachung Fehler frühzeitig erkannt und den einzelnen Prozessschritten zugewiesen werden können. Since the holding and transporting device is always in contact with at least one contact area during the transport of the intermediate product, the use of a tactile temperature measuring sensor is always possible. About the same information generated can be an efficient process monitoring or process control to build, which is independent of the surface properties of the board or the workpiece. A tactile temperature measuring sensor can achieve high measuring and repetitive accuracies with measuring deviations <= 1.5% and short response times of up to 2 seconds. Especially for workpieces with different temperature ranges equipped holding and transport devices according to the invention are of great advantage, since especially for these components via temperature monitoring errors detected early and can be assigned to the individual process steps.
Besonders vorteilhaft ist es, wenn der taktile Temperaturmesssensor zur Kontaktie- rung des Zwischenprodukts gegen eine elastische Vorspannung, insbesondere federvorgespannt, jedoch nachgiebig in oder an der Halte- und Transportvorrichtung verschieblich gehalten ist. Dadurch kann gewährleistet werden, dass der Temperaturmesssensor mit dem Werkstück auch bei Oberflächen- und Formabweichungen stets in Kontakt steht. It is particularly advantageous if the tactile temperature measuring sensor for contacting the intermediate product is displaceably held in or on the holding and transporting device against a resilient bias, in particular spring-biased but yielding. As a result, it can be ensured that the temperature measuring sensor is always in contact with the workpiece even in the event of surface and shape deviations.
Halte- und Transportvorrichtungen der vorbeschriebenden Art sind häufig an einem Roboterarm als ein Greifer mit einem beweglichen Greiferelement bzw. einer beweglichen Greifzange und einem demgegenüber starren Widerlager ausgebildet. Für derartige Halte- und Transportvorrichtungen ist es von Vorteil, den Temperaturmesssensor an einem sich beim Transport gegenüber dem Zwischenprodukt nicht bewegenden Bereich, hier dem Widerlager, anzuordnen, da dann Verbindungen, Kabelzuführleitungen etc. nicht beweglich geführt werden müssen. Retaining and holding devices of the above-described type are often formed on a robot arm as a gripper with a movable gripper element or a movable gripping tongs and a rigid abutment on the other hand. For such holding and transporting devices, it is advantageous to arrange the temperature measuring sensor on a non-moving area during transport relative to the intermediate product, in this case the abutment, since then connections, cable feed lines etc. need not be movably guided.
Bevorzugt ist der Temperaturmesssensor mit einer in die Halte- und Transportvorrichtung integrierten oder an diese angebundenen, separaten Auswerteeinheit ver- bunden, die beispielsweise der Aufzeichnung der Temperaturwerte, der Ermittlung von Grenzbereichen, der Warnung bei Überschreitung von Grenzbereichen etc. dienen kann. The temperature measuring sensor is preferably provided with a separate evaluation unit integrated into or connected to the holding and transport device. which can serve, for example, the recording of the temperature values, the determination of border areas, the warning when border areas are exceeded, etc.
Auf vorteilhafte Weise kann in die Halte- und Transportvorrichtung zusätzlich zumindest ein berührungslos messender Temperaturmesssensor integriert werden. Über diesen lässt sich dann in Abgleich mit den Werten des taktilen Temperaturmesssensors eine Information über den Emissionsfaktor des Werkstücks erhalten, ohne dass es aufwendiger Schleppmessungen bedarf. Die Ermittlung des Emissionsfaktors kann vollautomatisch erfolgen, wenn sowohl der taktile als auch der berührungslose Temperaturmesssensor mit einer Auswerteeinheit wie vorbeschrieben verbunden sind. Advantageously, at least one non-contact measuring temperature measuring sensor can additionally be integrated into the holding and transport device. In comparison with the values of the tactile temperature measuring sensor, this information can then be used to obtain information about the emission factor of the workpiece, without the need for complicated drag measurements. The determination of the emission factor can be fully automatic if both the tactile and non-contact temperature measuring sensor are connected to an evaluation unit as described above.
Unabhängig davon, ob die Auswerteeinheit mit Daten eines Temperaturmesssensors oder mehrerer Temperaturmesssensoren gespeist wird, ist es besonders vorteilhaft, wenn die Auswerteeinheit mit einer Steuer- oder Regeleinrichtung verbunden ist, über die der Transport des Zwischenproduktes bzw. der Platine beeinflusst werden kann. So können beispielsweise Produkte, deren gemessene Temperatur auf ein Ausschussprodukt schließen lassen, bereits vor der weiteren Umformung aussortiert werden, ohne dass noch weitere Prozessschritte investiert werden müssen. Sollte die Temperatur jedoch lediglich zu hoch sein, kann der Transport auch verlangsamt werden, so dass die Bauteile mit stets gleichbleibender Temperatur in das Umformwerkzeug eingelegt werden. Regardless of whether the evaluation unit is supplied with data from a temperature measuring sensor or a plurality of temperature measuring sensors, it is particularly advantageous if the evaluation unit is connected to a control or regulating device via which the transport of the intermediate product or of the circuit board can be influenced. Thus, for example, products whose measured temperature may indicate a reject product can be sorted out prior to further forming without the need for further process steps. However, should the temperature be too high, the transport may also be slowed down so that the components are loaded into the forming tool at a constant temperature.
Die erfindungsgemäße Halte- und Transportvorrichtung ist kostengünstig herstellbar. Auch lassen sich taktile Temperaturmesssensoren auf einfache Weise in das Hand- ling- bzw. Greifersystem integrieren. Dies ist sogar durch Anbau an vorhandene Halte- und Transportvorrichtungen möglich, wodurch diese nachrüstbar sind. The holding and transport device according to the invention is inexpensive to produce. In addition, tactile temperature measuring sensors can be easily integrated into the hand- integrate ling or gripper system. This is even possible by attachment to existing holding and transport devices, making them retrofitted.

Dort können sie als Entnahmeroboter die Grenztemperatur des Bauteils überwachen, die bei Entnahme aus der Form nicht überschritten werden darf, um beispielsweise später keine unzulässig hohen Schrumpfungen zu produzieren. Ist z.B. die Grenzentnahmetemperatur auf 200°C festgesetzt und wird durch die Sensorik der erfindungsgemäßen Vorrichtung eine Temperatur darüber festgestellt, so kann bereits unmittelbar bei dem darauf folgenden Bauteil reagiert werden, indem man dieses zur weiteren Abkühlung etwas länger in der Form belässt. So kann die Produktionsqualität noch weiter erhöht werden. The device according to the invention can also advantageously be used for temperature monitoring not only between the furnace and the mold but also for already formed intermediate products after leaving the shaping device. There they can monitor the limit temperature of the component as a removal robot, which must not be exceeded when removed from the mold, for example, later to produce any unacceptably high shrinkages. Is e.g. the boundary removal temperature is set to 200 ° C and is determined by the sensors of the device according to the invention, a temperature above, it can already be reacted directly in the subsequent component by leaving it for further cooling in the mold a little longer. Thus, the production quality can be further increased.
