Description

Die Erfindung bezieht sich auf einen Tisch, insbesondere Zuschneidtisch, zum Bearbeiten von flachen Werkstücken, insbesondere zum Schneiden von Stofflagen und derglei- chen, mit einer Tischplatte, welche eine Vielzahl von Luftlöchern aufweist, einer Druckquelle und einer Vakuumquelle und Mitteln, mit welchen die Luftlöcher mit der Druckquelle bzw. mit der Vakuumquelle in Verbindung ge-bracht werden können.The invention relates to a table, in particular Zuschneidtisch, for processing flat workpieces, in particular for cutting layers of fabric and the g managerial Chen, with a table plate having a plurality of air holes, a pressure source and a vacuum source and means by which g the air holes with the pressure source or the vacuum source-e can be introduced.

Solche Zuschneidtische ermöglichen es, Stofflagen spielend zu transportieren, weil durch die aus den Luftlöchern strömende Luft unter den Stofflagen ein Luftkissen gebildet wird. Durch Umschalten von der Druckquelle zur Vakuumquelle kann dann die Stofflage rasch fixiert werden. Als nachteilig hat sich jedoch erwiesen, dass der Tisch bei kleinflächigen Stofflagen seine Funktion vielfach nur ungenügend erfüllen kann, weil zu viel Luft durch die freibleibenden Luftlöcher fliesst und einen Abfall des Ueber- oder Unterdrucks veranlasst, so dass kein genügendes Luftkissen gebildet wird bzw. die Stofflage zuwenig gut fixiert wird.Such cutting tables make it easy to transport layers of fabric because an air cushion is formed under the layers of material by the air flowing out of the air holes. By switching from the pressure source to the vacuum source, the layer of fabric can then be quickly fixed. It has proven to be disadvantageous, however, that the table can often only insufficiently fulfill its function with small layers of fabric, because too much air flows through the unoccupied air holes and causes a drop in the overpressure or underpressure, so that no sufficient air cushion is formed Fabric layer is not fixed enough.

Bei einem bekannten Tisch ist zur Vermeidung dieser Nachteile unter dem Tisch eine Anzahl von Kammern vorgesehen, die automatisch von der Druckquelle bzw. der Vakuumquelle getrennt werden, wenn sich über dem darüberliegenden Tischabschnitt keine Stofflage befindet. Der Aufwand für eine entsprechende Steuerung ist aber sehr gross, so dass solche Tische mit automatischer Sektionalsteuerung sehr teuer sind.In a known table to avoid these disadvantages, a number of chambers is provided under the table, which are automatically from the pressure source or Vacuum source must be disconnected if there is no fabric layer above the table section above. However, the effort for a corresponding control is very large, so that such tables with automatic sectional control are very expensive.

Es.ist Aufgabe der vorliegenden Erfindung, die Nachteile bekannter Zuschneidtische zu beheben. Insbesondere soll der Tisch sich für die Verarbeitung von gross- und kleinflächigen Werkstücken eignen.It is the object of the present invention to overcome the disadvantages of known cutting tables. In particular, the table should be suitable for processing large and small workpieces.

Zur Lösung dieser Aufgabe sind gemäss der Erfindung Mittel zur Einstellung des Ueberdrucks bzw. des Unterdrucks entsprechend der Art der zu bearbeitenden Werkstücke vorgesehen. Dies ermöglicht es, eine Verstellung je nach Art und Grösse des Werkstücks vorzunehmen. Ist beispielsweise das Werkstück grossflächig, so werden dadurch die meisten Luftlöcher abgedeckt. Die Druckquelle muss daher relativ wenig Druckluft abgeben, um unter dem Werkstück ein geeignetes Luftkissen zu erzeugen, damit dieses leicht bewegt werden kann. Müssen umgekehrt relativ kleine Werkstücke bearbeitet werden, so kann zu einer grossen Zahl von Luftlöchern Luft ungehindert ausströmen, so dass ein Druckabfall entsteht und das Werkstück nicht mehr gut getragen wird. Durch entsprechende Er- höhuna der Druckluftabgabe der Druckquelle kann jedoch diesem Druckabfall entgegengewirkt werden, so dass unter dem Werkstück immer noch ein Luftkissen erzeugt wird, das dessen Bewegung auf dem Tisch erleichtert. Sind die Werkstücke zudem stark porös, so kann durch entsprechende Einstellung die Druckluftabgabe noch weiter erhöht werden. In entsprechender Weise ist auch die Saugleistung der Vakuumquelle steuerbar, um für jede Werkstückgrösse und Werkstückart eine genügende Saugkraft aufrecht zu erhalten, damit'das Werkstück haftet.To achieve this object, means for adjusting the overpressure or the underpressure are provided according to the invention according to the type of workpieces to be machined. This makes it possible to make an adjustment depending on the type and size of the workpiece. For example, if the workpiece is large, most of the air holes are covered. The pressure source therefore has to release relatively little compressed air in order to generate a suitable air cushion under the workpiece so that it can be moved easily. Conversely, if relatively small workpieces have to be machined, air can flow freely to a large number of air holes, so that there is a drop in pressure and the workpiece is no longer carried well. This pressure drop can, however, be counteracted by correspondingly increasing the compressed air delivery from the pressure source, so that an air cushion is still generated under the workpiece, which facilitates its movement on the table. If the workpieces are also highly porous, the compressed air output can be increased even further by making the appropriate settings. In a corresponding manner, the suction power of the vacuum source can also be controlled in order to maintain sufficient suction power for each workpiece size and type, so that the workpiece sticks.

Gemäss einem Ausführungsbeispiel der Erfindung sind die genannten Mittel zur Einstellung des Ueberdrucks bzw. des Unterdrucks entsprechend der Art der zu bearbeitenden Werkstücke durch einen zwischen Druckquelle und Vakuumquelle angeordneten Bypass mit einer Steuerklappe gebildet. Durch Verstellen der Steuerklappe kann also die Kraft geregelt werden, mit welcher das Werkstück angehoben oder festgehal- ten wird.According to an embodiment of the invention, the means mentioned for setting the overpressure or the underpressure are formed by a bypass with a control flap arranged between the pressure source and the vacuum source, in accordance with the type of workpieces to be machined. By adjusting the control valve so the force can be regulated with which the workpiece is lifted or fixed ehal- g th is.

Es ist aber auch möglich, dass als Druckquelle und als Vakuumquelle ein Ventilator dient, und dass als Mittel zur Einstellung des Ueberdrucks bzw. des Unterdrucks entsprechend der Art der zu bearbeitenden Werkstücke eine Vorrichtung zur Steuerung der Drehzahl des Ventilators vorgesehen ist. Diese Anordnung hat den Vorteil, dass der Energieverbrauch klein gehalten werden kann.However, it is also possible for a fan to serve as the pressure source and for the vacuum source, and for a device for controlling the speed of the fan to be provided as a means for setting the overpressure or underpressure in accordance with the type of workpieces to be processed. This arrangement has the advantage that the energy consumption can be kept low.

Ein Ausführungsbeispiel sieht einen Drucksensor vor, welcher an eine elektronische Steuereinheit angeschlossen ist, welche die Steuerklappe des Bypasses oder die Drehzahl des Ventilators regelt.One exemplary embodiment provides a pressure sensor which is connected to an electronic control unit which regulates the control flap of the bypass or the speed of the fan.

Ein Ausführungsbeispiel der Erfindung wird nun unter Bezugnahme auf die Zeichnung beschrieben. Es zeigt:

  • Figur 1 ein Prinzipschema eines Zuschneidtisches, und
  • Figur 2 einen Schnitt durch ein Luftloch in der Tischplatte des Zuschneidtisches.
An embodiment of the invention will now be described with reference to the drawing. It shows:
  • Figure 1 is a schematic diagram of a cutting table, and
  • Figure 2 shows a section through an air hole in the table top of the cutting table.

Der Zuschneidtisch weist eine Tischplatte 11 mit einer Vielzahl von Luftlöchern 13 auf. Unter der Tischplatte befindet sich eine Saug-/Druckkammer 15. Diese Druckkammer ist wahlweise mit einer Druckquelle oder einer Vakuumquelle verbindbar. Druckquelle und Vakuumquelle werden durch den Eingang 17 bzw. den Ausgang 19 des Ventilators 21 gebildet.The cutting table has a table top 11 with a plurality of air holes 13. There is a suction / pressure chamber 15 under the table top. This pressure chamber can optionally be connected to a pressure source or a vacuum source. Pressure source and vacuum source are formed by the inlet 17 and outlet 19 of the fan 21.

Es wäre aber auch möglich, z.B. eine Druckpumpe und eine Vakuumpumpe vorzusehen.But it would also be possible, e.g. to provide a pressure pump and a vacuum pump.

Zwischen der Saug-/Druckkammer 15 und dem Ventilator 21 sind der Filter 23 und der Schalldämpfer 25 angeordnet. Zwischen dem Ausgang 19 des Ventilators 21 und der Druckkammer 15 befindet sich der Schalldämpfer 27. Ein Klappensystem mit den Klappen 29, 31, 33 und 35, welche vom Motor 37 über das Gestänge 39 antreibbar sind, ermöglicht es, in der Kammer 15 Unterdruck oder Ueberdruck zu erzeuaen.The filter 23 and the silencer 25 are arranged between the suction / pressure chamber 15 and the fan 21. Between the outlet 19 of the fan 21 and the pressure chamber 15 there is the muffler 27. A flap system with the flaps 29, 31, 33 and 35, which can be driven by the motor 37 via the linkage 39, enables underpressure or 15 in the chamber To generate overpressure.

Von Bedeutung ist nun, dass zwischen dem Eingang 17 und dem Ausgang 19 ein Bypass 41 mit einer verstellbaren Steuerklappe 43 vorgesehen ist. Die Steuerklappe 43 kann von Hand oder durch ein Antriebsglied 45 verstellt werden, um entsprechend der Art des zu bearbeitenden Werkstücks den wirksamen Ueber- oder Unterdruck in der Saug-/Druckkammer 15 zu erzeugen. Es kann auch eine Regelung der Steuerklappe 43 mittels eines Druckfühlers 47 in der Saug-/Druckkammer 15 erfolgen. Zu diesem Zweck ist der Druckfühler 47 an das Steuergerät 49 angeschlossen, welches seinerseits mit dem Antriebsglied 45 verbunden ist. Das Steuergerät 49 weist ferner einen Verstellknopf 51 für die Einstellung des Ueberdrucks und einen Verstellknopf 53 für die Einstellung des Unterdrucks auf. Das Antriebsglied 37 ist ebenfalls mit der Steuereinrichtung 49 verbunden, welches zwei Steuerknöpfe 55, 57 für "Blasen" und "Saugen" aufweist. Mit dem Knopf 59 kann der Ventilator 21 ein- oder ausgeschaltet werden.It is important that a bypass 41 with an adjustable control flap 43 is provided between the input 17 and the output 19. The control flap 43 can be adjusted by hand or by a drive member 45 in order to generate the effective excess or negative pressure in the suction / pressure chamber 15 in accordance with the type of workpiece to be machined. The control flap 43 can also be regulated by means of a pressure sensor 47 in the suction / pressure chamber 15. For this purpose, the pressure sensor 47 is connected to the control device 49, which in turn is connected to the drive member 45. The control device 49 also has an adjustment button 51 for setting the positive pressure and an adjusting button 53 for setting the negative pressure. The drive member 37 is also connected to the control device 49, which has two control buttons 55, 57 for "blowing" and "suction". The fan 21 can be switched on or off with the button 59.

Dem Fachmann sind verschiedene Möglichkeiten offen, um das beschriebene Ausführungsbeispiel abzuändern, ohne vom Grundkonzept der Erfindung abzuweichen. So ist es beispielsweise möglich, anstelle der Druckknöpfe 55, 57 einen oder mehrere Fussschalter zu verwenden.Various possibilities are open to the person skilled in the art in order to change the exemplary embodiment described without deviating from the basic concept of the invention. For example, it is possible to use one or more foot switches instead of the push buttons 55, 57.

Die Tischplatte 11 besteht zweckmässigerweise aus Kunststoff mit einem Hartbelag 12. Solche Kunststoffplatten sind im Handel unter der Bezeichnung "Argolite Vollkern" erhältlich. Die Plattenstärke beträgt vorteilhaft 20 mm. Von erheblicher Bedeutung ist die Ausgestaltung der Luftlöcher 13. Beim Ausführungsbeispiel von Figur 2 besitzt das Luftloch 13 oben einen konischen Abschnitt 61. Auf die Stelle 63 mit dem kleinsten Durchmesser folgt unten ein konischer Abschnitt 65. Unter dem konischen Abschnitt 65 ist ein ungefähr zylinderischer Abschnitt 67 angeordnet, der einen etwa dreifach grösseren Durchmesser aufweist als die Stelle 63 mit dem kleinsten Durchmesser. Der Konuswinkel des oberen konischen Abschnitts 61 ist vorteilhaft kleiner als 90°, währenddem der Konuswinkel des unteren konischen Abschnitts 65 etwa 120° beträgt. Diese durch langwierige Versuche ermittelte Materialwahl für die Tischplatte und die Ausgestaltung der Luftlöcher hat sich in der Praxis bewährt. Die so gestalteten Luftlöcher neigen nur wenig zu Verstopfung durch Textilfasern und ermöglichen einen geräuscharmen Betrieb. Es hat sich in der Praxis gezeigt, dass gewöhnliche zylindrische Bohrungen zu Verstopfung durch Textilfasern neigen und erhebliche Geräuschprobleme verursachen. Durch die strömende Luft entstehen nämlich Pfeifgeräusche, welche bei einer Vielzahl von Luftlöchern sich sehr unangenehm auswirken können. Durch die beschriebene Formgebung werden jedoch die Pfeifgeräusche erheblich reduziert.The table top 11 suitably consists of plastic with a hard covering 12. Such plastic tops are commercially available under the name "Argolite solid core". The plate thickness is advantageously 20 mm. The configuration of the air holes 13 is of considerable importance. In the exemplary embodiment in FIG. 2, the air hole 13 has a conical section 61 at the top. The conical section 65 is followed by a conical section 65 at the bottom 63. Below the conical section 65 is an approximately cylindrical section 67 arranged, which has an approximately three times larger diameter than the point 63 with the smallest diameter. The cone angle of the upper conical section 61 is advantageously less than 90 °, while the cone angle of the lower conical section 65 is approximately 120 °. This choice of material for the table top and the design of the air holes, which was determined by lengthy tests, has proven itself in practice. The air holes designed in this way have little tendency to become blocked by textile fibers and enable quiet operation. It has been found in practice that ordinary cylindrical bores are prone to clogging by textile fibers and considerable noise PROBLEMS cause. The flowing air causes whistling noises, which can be very unpleasant with a large number of air holes. However, the whistling noises are considerably reduced by the shape described.
