Description

Die vorliegende Erfindung bezieht such auf eine Arbeitsein­richtung, insbesondere an einer Textilmaschine, mit einem längs einer Schiene hin und her verfahrbaren Arbeitsorgan.The present invention also relates to a working device, in particular on a textile machine, with a working member which can be moved back and forth along a rail.

Beim Arbeitsorgan kann es sich um eine Reinigungsvorrich­tung handeln, welche längs der Schiene über eine oder mehrere in Längsrichtung hintereinander aufgestellte Textil­maschine(n) hin und her verfahrbar ist, um diese perio­disch mittels Blas- und Saugluft von Staub und Flug zu rei­nigen. Die Blas- und Saugluft wird durch einen Ventilator im verfahrbaren Arbeitsorgan erzeugt und durch Luftleit­elemente an die Reinigungszonen geführt.The working organ can be a cleaning device which can be moved back and forth along the rail over one or more textile machine (s) arranged one behind the other in the longitudinal direction in order to periodically clean it of dust and flight by means of blowing and suction air. The blowing and suction air is generated by a fan in the movable working element and guided to the cleaning zones by air guiding elements.

Es ist bekannt, solche verfahrbaren Arbeitsorgane mit einer Steuerung zur Wahrnehmung von Hindernissen auszurüsten. Es können optische oder electromechanische Detektoren vor­handen sein, welche bei Wahrnehmung von Hindernissen die Bewegung des Arbeitsorgans anhalten und gegebenenfalls die Bewegungsrichtung umkehren.It is known to equip such movable working elements with a control for the detection of obstacles. Optical or electromechanical detectors can be present, which stop the movement of the work organ and, if necessary, reverse the direction of movement when obstacles are detected.

Den bekannten Lösungen ist gemeinsam, dass die Stromzu­führung sowohl für den Ventilator als auch für die Fahr­bewegung vom Netz aus über Stromschienen oder Schleppkabel erfolgt. Diese Art der Stromzuführung ist jedoch mit Nach­teilen verbunden, welche in der unerwünschten Funkenbil­dung und in oft auftretenden Kontaktunterbrüchen zwischen Stromschiene und Abnehmer bzw. in der umständlichen Führung der Schleppkabel besteht. Die Stromabnehmer sind einer starken Abnützung unterworfen und müssen oft erneuert wer­den. Auch die Steuerung der Bewegung des Arbeitsorganes ist aufwendig und kompliziert.The known solutions have in common that the power supply for the fan as well as for the travel movement takes place from the network via busbars or trailing cables. However, this type of power supply is associated with disadvantages, which consists in the undesirable spark formation and in frequently occurring interruptions in contact between the power rail and the consumer or in the cumbersome routing of the trailing cable. The pantographs are subject to heavy wear and often need to be replaced. Controlling the movement of the work organ is also complex and complex.

Zur Vermeidung dieser Nachteile ist bereits eine Antriebs­vorrichtung bekannt geworden, bei welcher die Wanderbe­wegung eines Wagens mit Ventilatorlaufrad mittels eines endlosen Transmissionsgliedes erfolgt, welches mit einem stationären Antriebsmotor verbunden ist.To avoid these disadvantages, a drive device has already become known in which the traveling movement of a car with a fan impeller takes place by means of an endless transmission member which is connected to a stationary drive motor.

Ausgehend von einer solchen Arbeitseinrichtung besteht die durch die Erfindung zu lösende Aufgabe darin, die Speisung der am Arbeitsorgan angeordneten, zur Wahrnehmung von Hindernissen dienenden Steuerung so zu bewerkstelligen, dass keine Schleppkabel oder dem Verschleiss unterworfene, mechanische Kontaktorgane benötigt werden. Zur Lösung die­ser Aufgabe dient die Arbeitseinrichtung, welche eines oder mehrere der in den Ansprüchen und/oder in der Be­schreibung aufgeführten Merkmale aufweist. Durch die Anord­nung eines mit dem Arbeitsorgan zusammen bewegten Generators wird die nur geringen Strom benötigende Speisung der Steue­rung in einfacher Weise bewerkstelligt.Starting from such a work device, the object to be achieved by the invention is to supply the control, which is arranged on the work organ and is used to detect obstacles, in such a way that no trailing cables or mechanical contact elements subject to wear are required. The work device, which has one or more of the features listed in the claims and / or in the description, is used to achieve this object. The arrangement of a generator which is moved together with the working member makes it easy to supply the control, which requires only a small amount of current.

Besonders vorteilhaft ist es, wenn der Generator in einem mit dem Arbeitsorgan bewegungsverbundenen Transmissions­glied Aufnahme findet, wobei der Generatorantrieb mit dem rotierenden Teil des Transmissionsgliedes in Verbindung steht.It is particularly advantageous if the generator is accommodated in a transmission element that is connected to the working element in a movement-related manner, the generator drive being connected to the rotating part of the transmission element.

Eine bevorzugte Lösung sieht vor, dass das verfahrbare Arbeitsorgan mit von einem Treibriemen um­fassten Transmissionsgliedern ausgerüstet ist, die sich aus je drei gleichachsig angeordneten Riemenscheiben zusammen­setzen, wobei die einzelnen Riemenscheiben des gleichen Transmissionsgliedes sich im Durchmesser voneinander unter­scheiden. In diesem Falle ist die im Anspruch 5 beschrie­bene Ausführung besonders empfehlenswert, da die genannte Ausbildung einen sehr einfachen Richtungswechsel des hin und her verfahrbaren Arbeitsorgans gestattet, wobei der Antrieb des Generators vom Richtungswechsel in keiner Weise beeinflusst wird und keinen Unterbruch erleidet.A preferred solution provides that the movable working member is equipped with transmission members which are comprised of a drive belt and which are each composed of three pulleys arranged with the same axis, the individual pulleys of the same transmission member differing in diameter from one another. In this case, the embodiment described in claim 5 is particularly recommended, since the said Training allows a very simple change of direction of the reciprocating work organ, the drive of the generator is in no way influenced by the change of direction and does not suffer an interruption.

  • Figure 2 seen the same working device frontally.
  • Figure 3 is a schematic representation of the detailed design of the drive and control parts. and

Die vorgeschlagene Arbeitseinrichtung ist gemäss dem Aus­führungsbeispiel als fahrbares Reinigungsgerät ausgebildet, welches entlang einer oder mehrerer hintereinander aufge­stellten Testilmaschinen, wie z.B. Spinn- oder Zwirn-­maschinen, hin- und herbeweglich ist, um diese mittels Blas- und Saugluft periodisch von Staub und Flug zu reini­gen. In den Figuren ist die als Reinigungsgerät ausgebil­dete Arbeitseinrichtung mit 1 bezeichnet. Sie weist einen auf zwei horizontalen Schienen 2 verfahrbaren Wagen 3 auf, an welchem Transmissionsglieder 16,17,18, ein Ventilator 5, sowie ein Steuergerät 6 mit Endschaltern 7a und 7b an­geordnet sind. Ferner sind noch vier Sensoren 8a bis 8d vor­gesehen, welche alle mit dem Steuergerät 6 durch Leitungen 9 in Verbindung stehen. An das Gehäuse des Ventilators 5 sind Luftleitelemente 10 angeschlossen, welche an beiden Seiten der Antriebseinrichtung 1 angeordnet sind, und sich annähernd bis zum Boden erstrecken. Durch diese Luftleit­elemente 10 werden Reinigungszonen 4 begrenzt, in welchen durch Druck- und Saugluft die Reinigung der Textilmaschinen erfolgt, die generell mit 11 bezeichnet sind. Die Arbeits­einrichtung 1 wird entlang diesen Maschinen 11 so hin­und herbewegt, dass die Maschinen 11 zwischen den Luft­leitelementen 10 sich in der Reinigungszone befinden.According to the exemplary embodiment, the proposed work device is designed as a mobile cleaning device which can be moved back and forth along one or more testile machines, such as spinning or twisting machines, to periodically clean them of dust and flight by means of blowing and suction air . In the figures, the working device designed as a cleaning device is designated by 1. It has a carriage 3 which can be moved on two horizontal rails 2 and on which transmission elements 16, 17, 18, a fan 5 and a control device 6 with limit switches 7a and 7b are arranged. Furthermore, four sensors 8a to 8d are also provided, all of which are connected to the control device 6 by lines 9 are connected. Air guiding elements 10 are connected to the housing of the fan 5 and are arranged on both sides of the drive device 1 and extend approximately to the bottom. These air-guiding elements 10 delimit cleaning zones 4, in which the textile machines, which are generally designated 11, are cleaned by compressed and suction air. The working device 1 is moved back and forth along these machines 11 in such a way that the machines 11 are located between the air guiding elements 10 in the cleaning zone.

Zum Antrieb ist am einen Ende des durch die Arbeitseinrich­tung zurückzulegenden Weges ein Elektromotor 12 ortsfest angeordnet (Fig. 3), wobei zwischen der Antriebsscheibe 13 des Elektromotors 12 und einer Umlenkscheibe 14 am anderen Ende des Arbeitsweges ein Transmissionselement in der Form eines endlosen Treibriemens 15 gespannt ist. Der endlose Treibriemen 15 umschlingt auch die drei Trans­missionsglieder 16,17,18, wie dies nachfolgend beschrie­ben wird. Jedes Transmissionsglied 16,17,18 setzt sich aus drei Riemenscheiben 16a,b,c; 17a,b,c und 18a,b,c zusammen, wobei die einzelnen Riemenscheiben des gleichen Trans­missionsgliedes sich im Durchmesser voneinander unterschei­den. Die Abmessungen sind so gewählt, dass die unterste Riemenscheibe 16c im Durchmesser kleiner ist als die oberste Riemenscheibe 16a, welche wiederum kleiner ist als die mittlere Scheibe 16b. Genau gleich sind die Verhältnisse bezüglich der Transmissionsglieder 17 und 18. Die Anord­nung ist dabei so getroffen, dass der hintere Trum 15a des Treibriemens konstant über die Riemenscheiben 16a, 17a und 18a, diese entlang einer Schlangenlinie umfassend, ge­führt ist, während der vordere Trum 15b wahlweise über die unteren Riemenscheiben 16c,17c,18c oder über die mittleren Scheiben 16b,17b und 18b bzw. über die oberen Scheiben 16a,17a und 18a geführt werden kann. Dieser vordere Trum 15b umfasst die Scheiben 16,17,18 in jedem Falle ent­gegengesetzt zum, hinteren Trum 15a. Zur Verstellung des Trums 15b dient eine Umstellvorrichtung 19, die aus einem Elektromagneten 20 sowie aus einem den Trum 15b umfassen­den Führungsorgan 21 besteht, das durch den Elektromagneten 20 in den Pfeilrichtungen 22 verschiebbar ist. Eine Leitung 23 verbindet den Elektromagneten 20 mit dem Steuergerät 6. Anstelle des Elektromagneten 20 könnte auch ein Elektro­motor verwendet werden.For the drive, an electric motor 12 is arranged in a fixed position at one end of the path to be covered by the working device (FIG. 3), a transmission element in the form of an endless drive belt 15 being stretched between the drive pulley 13 of the electric motor 12 and a deflection pulley 14 at the other end of the working path is. The endless drive belt 15 also wraps around the three transmission links 16, 17, 18, as will be described below. Each transmission link 16, 17, 18 is made up of three pulleys 16a, b, c; 17a, b, c and 18a, b, c together, the individual pulleys of the same transmission member differing in diameter from one another. The dimensions are chosen such that the lowest pulley 16c is smaller in diameter than the uppermost pulley 16a, which in turn is smaller than the central pulley 16b. The relationships with respect to the transmission members 17 and 18 are exactly the same. The arrangement is such that the rear run 15a of the drive belt is constantly guided over the belt pulleys 16a, 17a and 18a, which comprises a serpentine line, while the front run 15b either over the lower pulleys 16c, 17c, 18c or over the middle ones Disks 16b, 17b and 18b or can be guided over the upper disks 16a, 17a and 18a. In any case, this front run 15b comprises the disks 16, 17, 18 opposite to the rear run 15a. For the adjustment of the strand 15b, a changeover device 19 is used, which consists of an electromagnet 20 and a guide element 21 which surrounds the strand 15b and can be displaced in the arrow directions 22 by the electromagnet 20. A line 23 connects the electromagnet 20 to the control device 6. Instead of the electromagnet 20, an electric motor could also be used.

Da bei allen drei Transmissionsgliedern 16,17,18 die unter sich gleichen unteren Riemenscheiben 16c,17c und 18c klei­ner sind als die wiederum unter sich gleichen oberen Rie­menscheiben 16a,17a und 18a, wird durch die auftretende Differenz in der Umfangsgeschwindigkeit an den oberen Scheiben 16a,17a,18a einerseits und an den mittleren oder unteren Scheiben 16b,17b,18b bzw. 16c,17c,18c andererseits eine Bewegung des Wagens 3 in einer Richtung erzeugt. Falls der Trum 15b mit Hilfe der Umstellvorrichtung 19 von den unteren Riemenscheiben 16c,17c,18c auf die mittleren Riemen­scheiben 16b,17b,18b gewechselt wird, so entsteht eine in der anderen Richtung wirksame Geschwindigkeitsdifferenz zur Erzeugung einer entgegengesetzen Bewegung. Falls die Rie­menscheiben 16a,17a,18a mit je einer weiteren Rille zur Führung des Trums 15b versehen werden, so ist es möglich, den Trum 15b vollständig nach oben auf die Riemenscheiben 16a,17a und 18a zu verschieben. In diesem Falle läuft zwar der Treibriemen 15, der Wagen 3 bewegt sich aber nicht.Since in all three transmission elements 16, 17, 18 the lower pulleys 16c, 17c and 18c, which are the same under each other, are smaller than the upper pulleys 16a, 17a and 18a, which in turn are the same, the difference in the peripheral speed occurring on the upper pulleys 16a , 17a, 18a on the one hand and on the middle or lower disks 16b, 17b, 18b or 16c, 17c, 18c on the other hand produces a movement of the carriage 3 in one direction. If the strand 15b is changed from the lower pulleys 16c, 17c, 18c to the middle pulleys 16b, 17b, 18b with the aid of the changeover device 19, a speed difference which is effective in the other direction is produced to produce an opposite movement. If the pulleys 16a, 17a, 18a are each provided with a further groove for guiding the strand 15b, it is possible to move the strand 15b completely upward onto the pulleys 16a, 17a and 18a. In this case, the drive belt 15 runs, but the carriage 3 does not move.

Die Stromversorgung des Steuergerätes 6 erfolgt mit Hilfe eines Generators 24, welcher in das Transmissionsglied 16 eingebaut ist. In der Fig. 4 ist der nähere Aufbau des Generators 24 in Verbindung mit dem Transmissionsglied 16 dargestellt. Der Generator 24 weist eine Welle 28 mit den Riemenscheiben 16a,16b,16c auf. Das Polrad ist mit 29 und die Ankerwicklung mit 32 bezeichnet. Durch die Rotation des Transmissionsgliedes 16 rotiert auch das Polrad 29 des Generators 24 mit und es wird in den feststehenden Anker­wicklungen 32 Strom induziert. Durch eine Leitung 25 wird das Steuergerät 6 mit Strom versorgt und zwar unabhängig von der Bewegungsrichtung des Wagens 3. In der beschrie­benen Weise wird auch dafür gesorgt, dass auch bei still­stehendem Wagen 3 kein Stromausfall entsteht.The power supply to the control device 6 takes place with the aid of a generator 24 which is built into the transmission element 16. 4 is the detailed structure of the Generator 24 shown in connection with the transmission member 16. The generator 24 has a shaft 28 with the pulleys 16a, 16b, 16c. The pole wheel is designated 29 and the armature winding 32. Due to the rotation of the transmission member 16, the magnet wheel 29 of the generator 24 also rotates and current is induced in the fixed armature windings 32. The control device 6 is supplied with power by a line 25, regardless of the direction of movement of the carriage 3. In the manner described, it is also ensured that there is no power failure even when the carriage 3 is stationary.

Bei der Bewegung der Arbeitseinrichtung 1 entlang der Schienen 2 strömt durch die genannten Luftleitelemente 10 die mit in der Höhe verteilt angeordneten Düsen 26 ver­sehen sind, Druckluft oder es wird Luft angesogen. Dazu dient der Ventilator 5, dessen Welle 27 eine Verlängerung der gemeinsamen Welle der Riemenscheiben 17a bis 17c bil­det und durch das Transmissionsglied 17 angetrieben wird.When the working device 1 moves along the rails 2, compressed air flows through said air-guiding elements 10, which are provided with vertically distributed nozzles 26, or air is sucked in. The fan 5 is used for this purpose, the shaft 27 of which forms an extension of the common shaft of the pulleys 17a to 17c and is driven by the transmission member 17.

Die am Wagen 3 angeordneten Endschalter 7a und 7b arbei­ten mit an beiden Enden der Bewegungsbahn des Wagens 3 vor­handenen Anschlägen zusammen und sind durch Leitungen 30,31 mit dem Steuergerät 6 verbunden. Im Bereiche dieser Anschläge wird einer der Endschalter 7a oder 7b umgestellt, wodurch das Steuergerät 6 den Elektromagneten 20 zur Verstellung des Führungsorgans 21 für den Treibriemen betätigt. Der Trum 15b wird von den unteren Riemenscheiben 16c,17c,18c auf die mittleren Scheiben 16b,17b,18b verschoben, die grösser sind als die oberen, vom Trum 15a umschlungenen Riemenscheiben 16a,17a und 18a, so dass ein Richtungswechsel in der Bewegung des Wagens 3 erfolgt. Darüberhinaus ist noch zu erwähnen, dass die Sensoren 8a bis 8d an den Luft­leitelementen 10 angeordnet, und z.B. als Ultraschall­ Sensoren ausgebildet sind, welche bei Annäherung der Luft­leitelemente 10 an ein Hindernis ebenfalls eine Unsteuerung des Wagens 3 samt Luftleitelementen 10 bewirken. Beim Auf­tauchen eines Hindernisses gibt der das Hindernis wahr­nehmende Sensor 8a bis 8d ein Signal an das Steuergerät 6, welches in der erwähnten Weise den Elektromagneten 20 zur Umstellung des Führungsorganes 21 beeinflusst, wo­durch die Bewegungsrichtung des Wagens 3 geändert wird. In dieser Weise können Kollisionen der Luftleitelemente mit Hindernissen, die in der Bewegungsbahn der Luftelemente liegen, vermieden werden.The limit switches 7a and 7b arranged on the carriage 3 cooperate with stops present at both ends of the movement path of the carriage 3 and are connected to the control device 6 by lines 30, 31. In the area of these stops, one of the limit switches 7a or 7b is changed over, as a result of which the control device 6 actuates the electromagnet 20 to adjust the guide member 21 for the drive belt. The strand 15b is shifted from the lower pulleys 16c, 17c, 18c to the middle pulleys 16b, 17b, 18b, which are larger than the upper pulleys 16a, 17a and 18a, which are wrapped by the strand 15a, so that a change of direction in the movement of the Wagens 3 takes place. In addition, it should also be mentioned that the sensors 8a to 8d are arranged on the air guiding elements 10 and, for example, as ultrasound Sensors are formed which, when the air guiding elements 10 approach an obstacle, also cause the carriage 3 together with the air guiding elements 10 to be uncontrolled. When an obstacle appears, the sensor 8a to 8d, which detects the obstacle, sends a signal to the control device 6, which influences the electromagnet 20 for converting the guide member 21 in the manner mentioned, as a result of which the direction of movement of the carriage 3 is changed. In this way, collisions of the air guide elements with obstacles that lie in the path of movement of the air elements can be avoided.

Die Zuverlässigkeit der Sensoren 8a bis 8d kann noch er­höht und die Möglichkeit von Fehlschaltungen ausgeschlos­sen werden, falls jeweils nur die in der Fahrtrichtung lie­genden Sensoren eingeschaltet sind.The reliability of the sensors 8a to 8d can be increased further and the possibility of incorrect switching can be excluded if only the sensors in the direction of travel are switched on.

In der beschriebenen Weise erfolgt der energieintensive Antrieb für den Wagen 3 und für den Ventilator 5 durch den endlosen Treibriemen 15, welcher vom ortsfesten Elektro­motor 12 bewegt wird, während der minim benötigte Strom mit Hilfe des auf dem fahrbaren Wagen 3 angeordneten bürstenlosen Generators 24 erzeugt wird.In the manner described, the energy-intensive drive for the carriage 3 and for the fan 5 takes place through the endless drive belt 15, which is moved by the stationary electric motor 12, while the minimally required current is generated with the aid of the brushless generator 24 arranged on the movable carriage 3 .
