Die vorliegende Erfindung betrifft eine Tablettenpressvorrichtung mit einer Tablettenpresse, einem Steuerrechner, der die motorischen Verstellmöglichkeiten der Tablettenpresse steuert und regelt, und einem Bedienrechner, der die Ein- und Ausgabe von Daten zur Bedienung der Tablettenpresse zuläßt.The present invention relates to a tablet press device with a tablet press, a control computer, which the motor adjustment options Tablet press controls and regulates, and an operating computer, the input and output of data for operating the tablet press.
Moderne Tablettenpressen können bis zu über 1 Millionen Tabletten pro Stunde pressen. Die Steuerung der Tablettenpresse erfolgt hierbei über einen eigens vorgesehenen Steuer- bzw. Prozeßrechner, der Daten an Meßstellen in der Tablettenpresse erfaßt und anhand der erfaßten Daten eine Regelung der Maschine vornimmt. Ferner ist ein separater Rechner als Bedienrechner vorgesehen. Der Bedienrechner dient dazu, Betriebszustandsdaten auszuwerten, produktionsspezifische Größen sich anzusehen und beispielsweise Probeläufe und dergleichen durchzuführen. Bei dem Bedienrechner handelt es sich in der Regel um einen herkömmlichen Industrie-PC, der über ein Netzwerk mit dem Steuerrechner verbunden ist. Die Positionierung des Bedienrechners relativ zu der Tablettenpresse wird hierbei durch die Kabelverbindung beschränkt. Zudem hat sich herausgestellt, daß die Kabelverbindung mit der Tablettenpresse Ursache für Fehler sind, die von einer Bedienperson nicht richtig erkannt werden oder der Tablettenpresse zugeordnet werden.Modern tablet presses can handle up to 1 million tablets per hour press. The tablet press is controlled via a specially provided one Control or process computer, the data at measuring points in the tablet press recorded and controls the machine based on the recorded data. Further a separate computer is provided as the operating computer. The operator computer serves to evaluate operating status data, look at production-specific variables and to conduct test runs and the like, for example. In which Operator computer is usually a conventional industrial PC, which is connected to the control computer via a network. The positioning of the Operating computer relative to the tablet press is hereby through the cable connection limited. It has also been found that the cable connection with The tablet press are the cause of errors that are incorrect by an operator recognized or assigned to the tablet press.
Der Erfindung liegt die Aufgabe zugrunde, eine Tablettenpressvorrichtung bereit zu stellen, die weniger anfällig für Fehler ist und eine einfache Bedienung und Reinigung gestattet. The object of the invention is to prepare a tablet press device that is less prone to errors and easy to use and clean allowed.
Die erfindungsgemäße Aufgabe wird durch eine Tablettenpressvorrichtung mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen finden sich in den Unteransprüchen.The object of the invention is achieved by a tablet press device with the Features solved from claim 1. Advantageous refinements can be found in the Dependent claims.
Bei der erfindungsgemäßen Tablettenpressvorrichtung ist die Tablettenpresse mit ihren Motoren und Sensoren zum Steuerrechner über eine Kabelverbindung zum Hochgeschwindigkeitsdatentransfer verbunden. Gleichzeitig ist die Tablettenpresse und der Bedienrechner jeweils mit einer Sende- und Empfangseinheit versehen, um über eine kabellose Funkverbindung Daten und Steuerbefehle auszutauschen. Bei der erfindungsgemäßen Lösung wird für den Steuer- bzw. Prozeßrechner eine Hochgeschwindigkeitsdatentransferverbindung vorgesehen, die es gestattet, ein stabiles Regelverhalten auch bei großer Produktionsgeschwindigkeit zu erzielen. Gleichzeitig ist bei der erfindungsgemäßen Tablettenpressvorrichtung die Verbindung der Tablettenpresse zu dem Bediener über eine Sende- und Empfangseinheit vorgesehen, so daß Daten und Steuerbefehle über Funk ausgetauscht werden. Zwar eignet sich eine solche Datenverbindung nicht zur Übertragung mit einer hohen Datenrate, doch ist die bei der Verwendung von Sende-/Empfangseinheiten über Funk und/oder Infrarot erzielbare Datenrate für den Bedienrechner ausreichend. Mit dem drahtlosen Datenaustausch werden Kommunikationskabel im Produktionsraum vermieden, wodurch ein geringerer Aufwand bei der Reinigung des Produktionsraums anfällt. Hinzu kommt, daß bei der Installation ein geringerer Verdrahtungsaufwand anfällt und eine Herstellung von Kabeln mit einer kundenspezifischen Kabellänge entfallen kann. Zudem entfallen Fehler an den Bedienrechnern, die durch eine falsche oder unvollständige Verbindung mit der Tablettenpresse auftreten. Als weiterer Vorteil der erfindungsgemäßen kabellosen Verbindung ist auch zusehen, daß im Produktionsraum eine Unfallgefahr ausgeräumt wird. In the tablet press device according to the invention, the tablet press is included their motors and sensors to the control computer via a cable connection to High speed data transfer connected. At the same time is the tablet press and the operating computer each with a transmitting and receiving unit in order Exchange data and control commands via a wireless radio connection. at The solution according to the invention becomes a high-speed data transfer connection for the control or process computer provided that allows a stable To achieve control behavior even at high production speeds. simultaneously is the connection of the tablet press device according to the invention Tablet press provided to the operator via a transmitting and receiving unit, so that data and control commands are exchanged via radio. Suitable Such a data connection is not suitable for transmission at a high data rate, however, this is the case when using transmitting / receiving units via radio and / or Data rate achievable by infrared is sufficient for the operating computer. With the wireless Communication cables are avoided in the production room, which means less effort in cleaning the production room. In addition, the installation requires less wiring and the production of cables with a customer-specific cable length is eliminated can. In addition, there are no errors on the operating computers caused by an incorrect or incomplete connection with the tablet press. Another advantage The wireless connection according to the invention can also be seen in the production room an accident risk is eliminated.
In einer bevorzugten Weiterbildung ist zusätzlich mindestens ein Handbediengerät vorgesehen, das mit einer Sende-/ und Empfangseinheit versehen ist, um über eine kabellose Verbindung mit der Tablettenpresse und/oder dem Bedienrechner Daten auszutauschen. Ein mobiles Handbedienungsgerät besitzt den Vorteil, daß beispielsweise bei einem Probelauf eine Bedienperson sich frei um die Tablettenpresse bewegen kann.In a preferred development, at least one handheld control device is additionally provided provided, which is provided with a transmitting / receiving unit, via a wireless connection with the tablet press and / or the operating computer data exchange. A mobile handheld device has the advantage that for example, during a test run, an operator freely around the tablet press can move.
Auch kann der Bedienrechner über seine Sende-/Empfangseinheit Daten mit einem oder mehreren Peripheriegeräten austauschen und diese ansteuern. Hierdurch entfällt eine Verkabelung der Peripheriegeräte mit dem Bedienrechner für die Tablettenpresse. Es kann beispielsweise, wenn ein Drucker als Peripheriegerät ausgetauscht werden soll, der Drucker entfernt werden und ein neuer Drucker in die Nähe des Bedienrechners gestellt werden, ohne daß ein Stecker hierfür erforderlich wäre.The operating computer can also transmit data with a via its transmitter / receiver unit exchange or control several peripheral devices. This eliminates a wiring of the peripheral devices with the operating computer for the tablet press. It can be, for example, when a printer is replaced as a peripheral the printer should be removed and a new printer near the Operating computer can be provided without a plug being required for this.
Für die drahtlose Übertragung zwischen den Sende- und Empfangseinheiten kann ebenfalls Bluetooth eingesetzt werden.For wireless transmission between the sending and receiving units Bluetooth can also be used.
