Je nach Außendurchmesser des Coils 2 wird die Richtmaschine 6 zum Abwickler 4 bzw. zum Coil 2 hin horizontal verfahren; zusätzlich wird die Neigung der Richtmaschine 6 ebenfalls entsprechend dem Außendurchmesser des Coils 2 so eingestellt, dass der Bandmaterialanfang optimal in die Richtmaschine 6 bzw. in deren Bandeinlauf 9 einführbar ist. Die Ausrichtung der Richtmaschine 6 erfolgt automatisch mittels der vertikalen Positionierantriebe 10, 14 am Bandeinlauf 9 bzw. Bandauslauf 12 der Richtmaschine 6. Die Laser-Analog-Lichtschranke des Abwicklers 4 kann weiterhin genutzt werden, um ein Abzugsbremsmoment einer Ablaufbremse des Abwicklers 4 zu steuern.A strip material start of a processed coil 2, which is located on the unwinder 4, is held by a hydraulically operated pressure roller with hydraulic drive and multi-disc brake. The diameter of coil 2 is detected by a laser-analogue light barrier. Depending on the outer diameter of the coil 2, the straightening machine 6 is moved horizontally to the unwinder 4 or to the coil 2; in addition, the inclination the straightening machine 6 also set according to the outer diameter of the coil 2 so that the beginning of the strip material is optimally inserted into the straightening machine 6 and in the band inlet 9. The alignment of the straightening machine 6 takes place automatically by means of the vertical positioning drives 10, 14 at the belt inlet 9 and belt outlet 12 of the straightening machine 6. The laser-analogue light barrier of the unwinder 4 can furthermore be used to control a withdrawal brake torque of a drain brake of the unwinder 4.

Bei sich allmählich verringerndem Außendurchmesser des Coils 2 wird mittels eines fallenden Bremsmoments die Abzugkraft, mit der das Bandmaterial 3 vom Abwickler 4 bzw. vom Coil 2 abgezogen wird, konstant gehalten, wobei bei der Einstellung selbstverständlich auch unterschiedliche Bandquerschnitte unterschiedlicher Coils 2 berücksichtigt werden.With gradually decreasing outer diameter of the coil 2, the withdrawal force with which the strip material 3 is withdrawn from the unwinder 4 and from the coil 2, is kept constant by means of a falling braking torque, wherein, of course, different band cross sections of different coils 2 are taken into account in the setting.

Vor Beginn des Richtbetriebs wird die Richtmaschine 6 mittels des horizontalen Positionierantriebs 8 in einen den Bandquerschnitt, insbesondere die Banddicke, berücksichtigenden, optimalen Abstand zum Abwickler 4 bzw. zum Coil 2 verfahren, wobei diese Positionierung der Richtmaschine 6 automatisch erfolgt. Wenn dieser optimale Abstand zwischen der Richtmaschine 6 und dem Abwickler 4 bzw. dem Coil 2 eingestellt ist, kann der Vorschub 5, ohne dass eine Bandschlaufe zwischen dem Bandauslauf 12 der Richtmaschine 6 und der Einlaufseite 17 des Vorschubs 5 übermäßig schwingt, das Bandmaterial 3 mit optimaler Hubzahl in die in den Figuren nicht gezeigte Weiterverarbeitungsmaschine weiterleiten.Before the start of the straightening operation, the straightening machine 6 is moved by means of the horizontal positioning drive 8 into a belt cross-section, in particular the belt thickness, taking into account the optimal distance from the unwinder 4 or the coil 2, this positioning of the straightening machine 6 taking place automatically. If this optimum distance between the leveler 6 and the unwinder 4 or the coil 2 is set, the feed 5, without a belt loop between the belt outlet 12 of the leveler 6 and the inlet side 17 of the feed 5 oscillates excessively, the strip material 3 with forward optimum stroke rate in the further processing machine, not shown in the figures.

Wenn ein neues Coil 2 auf dem Abwickler 4 eingesetzt wird, so dass ein neuer Bandmaterialanfang vorliegt, ergibt sich folgender Ablauf:If a new coil 2 is used on the unwinder 4, so that there is a new beginning of the strip material, the following sequence results:

Die beiden vertikalen Positionierantriebe 14 am Bandauslauf 12 der Richtmaschine 6 und der vertikale Positionierantrieb 10 am Bandeinlauf 9 der Richtmaschine 6 verfahren die Richtmaschine 6 in eine optimale Position, in der die Richtmaschine 6 etwa in Richtung einer Tangente des Bandmaterialanfangs, der von der hydraulisch betätigten Andrückrolle des Abwicklers 4 gehalten wird, so dass der neue Bandmaterialanfang in einfacher Weise in den Spalt zwischen geöffneten Vorbiege- und Einzugrollen der Richtmaschine 6 eingebracht werden kann. Die Verstellvorgänge zur Ausrichtung der Vertikalposition und der Neigung der Richtmaschine 6 beginnen simultan mit der horizontalen Verfahrung der Richtmaschine 6 mittels des horizontalen Positionierantriebs 8, so dass aufgrund der Gleichzeitigkeit der Verstellbewegungen Rüstzeit eingespart und dementsprechend Produktionszeit gewonnen werden kann.The two vertical positioning 14 on the belt outlet 12 of the leveler 6 and the vertical positioning 10 at the belt inlet 9 of the leveler 6 process the leveler 6 in an optimal position in which the leveler 6 approximately in the direction of a tangent of Bandmaterialanfangs, of the hydraulically operated pressure roller the unwinder 4 is held, so that the new beginning of the strip material can be introduced in a simple manner into the gap between opened pre-bending and drawing-in rollers of the straightening machine 6. The adjustment operations for aligning the vertical position and the inclination of the straightening machine 6 start simultaneously with the horizontal Verfahrung the leveler 6 by means of the horizontal positioning drive 8, so that saved due to the simultaneity of the adjustment setup time and accordingly production time can be obtained.

Am Bandeinlauf 9 der Richtmaschine 6 ist ein hydraulisch schwenkbarer Bandüberleittisch 18 vorgesehen. Der Bandüberleittisch 18 besteht aus zwei Tischteilen 19, 20, die mittels eines Gelenks 21 miteinander verbunden sind. Beim Anfahren des Bandüberleittisches 18 bei der horizontalen Verfahrung der Richtmaschine 6 knickt der vordere Tischteil 19 ab. Durch dieses Abknicken wird ein Näherungsschalter betätigt, der nacheinander die folgenden Vorgänge einleitet:

  • Anhalten der horizontalen Verfahrung der Richtmaschine 6,
  • Aufwärtsschwenken der Richtmaschine 6 um deren Schwenklager 13, bis die schräg verlaufende Vorderkante des vorderen Tischteils 19 vom Außenumfang des Coils 2 entfernt ist, damit bei der darauf folgenden Drehung des Coils 2 am Abwickler 4 die Außenmantelfläche des Coils 2 nicht beschädigt wird, wobei der Abstand zwischen der Vorderkante des vorderen Tischteils 19 und der Außenmantelfläche des Coils 2 ca. 5 mm bis 10 mm betragen sollte,
  • Einschalten eines hydromotorischen Wickelantriebs des Abwicklers 4 und eines hydromotorischen Andruckrollenantriebs, wobei jeweils eine Lamellenbremse freigeschaltet wird.
At the belt inlet 9 of the straightening machine 6, a hydraulically pivotable tape transfer table 18 is provided. The tape transfer table 18 consists of two table parts 19, 20, which are connected to each other by means of a hinge 21. When starting the tape transfer table 18 in the horizontal Verfahrung the leveler 6 bends the front table part 19 from. This kinking operation activates a proximity switch which initiates the following operations in succession:
  • Stopping the horizontal movement of the straightening machine 6,
  • Swinging up the straightening machine 6 about its pivot bearing 13 until the oblique front edge of the front Table part 19 is removed from the outer circumference of the coil 2, so that in the subsequent rotation of the coil 2 on the unwinder 4, the outer circumferential surface of the coil 2 is not damaged, wherein the distance between the front edge of the front table part 19 and the outer circumferential surface of the coil 2 approximately 5 mm to 10 mm,
  • Switching on a hydromotorischen winding drive of the unwinder 4 and a hydromotorischen Andruckrollenantriebs, wherein in each case a multi-disc brake is released.

Der Bandmaterialanfang gleitet dann über den Bandüberleittisch 18 in die geöffneten Biege- und Einzugrollen der Richtmaschine 6. In Laufrichtung des Bandmaterials hinter der oberen Einzugrolle der Richtmaschine ist ein Sensor für die Erfassung des Bandmaterialanfangs angeordnet. Sobald der Sensor die Ankunft des Bandmaterialanfangs erfasst, erfolgt eine hydraulische Anstellung der oberen Einzugrolle der Richtmaschine 6.The beginning of the strip material then slides over the strip transfer table 18 into the open bending and drawing rollers of the leveling machine 6. In the direction of the strip material behind the upper feed roller of the leveler, a sensor for detecting the beginning of the strip material is arranged. As soon as the sensor detects the arrival of the strip material beginning, a hydraulic adjustment of the upper feed roller of the leveler 6 takes place.

Die Anstellkraft der oberen Einzugrolle der Richtmaschine 6 wird mittels eines Proportionaldruckregelventils und eines Drucksensors entsprechend der Bandbreite und der Festigkeitseigenschaften des Bandmaterials 3 vorgegeben. Danach stellt sich die Vorbiegerolle, die in Bandlaufrichtung stromauf der Einzugrol'le angeordnet ist, in ihre vorbiegeposition. Der Anstellhub der Vorbiegerolle wird, wenn sich diese in der Vorbiegeposition befindet, durch einen Wegaufnehmer in Abhängigkeit von der Dicke des Bandmaterials angehalten. Befindet sich die Vorbiegerolle in ihrer Vorbiegeposition, wird die Antriebseinrichtung der Richtmaschine 6 eingeschaltet, mittels der die Biege-, Einzug- und Richtrollen der Richtmaschine in Drehbewegung versetzt werden. Hierdurch wird dann der Bandmaterialanfang aus der Richtmaschine 6 herausgetrieben. Ein weiterer Sensor, der am Bandauslauf 12 der Richtmaschine 6 angeordnet ist, erfasst den Bandmaterialanfang und setzt den horizontalen Positionierantrieb 8 der Richtmaschine 6 bzw. den Servomotor und den Servoumrichter desselben in Betrieb. Die Richtmaschine 6 wird dann mittels des horizontalen Positionierantriebs 8 in Richtung zum Vorschub 5 verfahren. Bei der Bewegung der Richtmaschine 6 aus dem Bereich des Abwicklers 4 in Richtung zum Vorschub 5 wird die Richtmaschine 6 mittels der vertikalen Positionierantriebe 10, 14 in die Horizontale versetzt. Danach wird die Richtmaschine 6 mittels der vertikalen Positionierantriebe 10, 14 in eine Vertikalposition verbracht, die der Höhe der Einlaufseite 17 des Vorschubs 5 entspricht, die etwa der Höhe von Unterwerkzeugen einer dem Vorschub 5 nachgeschalteten Presse entsprechen kann. Derartige Unterwerkzeuge von Pressen können z.B. Einlaufhöhe von 100 mm bis 450 mm haben; daher ist es für eine problemlose Übergabe des Bandmaterialanfangs in den Vorschub 5 äußerst vorteilhaft, wenn die Richtmaschine 6 bei der Übergabe des Bandmaterialanfangs in den Vorschub 5 das gleiche Vertikalniveau wie der Vorschub 5 und damit der Einlauf der nachgeschalteten Presse hat.The contact force of the upper feed roller of the leveler 6 is determined by means of a proportional pressure control valve and a pressure sensor according to the bandwidth and the strength properties of the strip material 3. Thereafter, the Vorbiegerolle, which is arranged in the strip running direction upstream of the Einzugsrol'le, in its pre-bending position. The Anstellhub the Vorbiegerolle is, if this is in the Vorbiegeposition stopped by a transducer in dependence on the thickness of the strip material. The Vorbiegerolle is in its Vorbiegeposition, the drive means of the leveler 6 is turned on, by means of the bending, retraction and straightening rollers of the leveler be set in rotary motion. As a result, the beginning of the strip material is then driven out of the straightening machine 6. Another sensor, which is arranged on the belt outlet 12 of the straightening machine 6, detects the beginning of the strip of material and sets the horizontal positioning drive 8 of the straightening machine 6 or the servomotor and the servo converter thereof into operation. The straightening machine 6 is then moved by means of the horizontal positioning drive 8 in the direction of the feed 5. During the movement of the straightening machine 6 out of the area of the unwinder 4 in the direction of the feed 5, the straightening machine 6 is offset by means of the vertical positioning drives 10, 14 in the horizontal. Thereafter, the leveler 6 is moved by means of the vertical positioning drives 10, 14 in a vertical position corresponding to the height of the inlet side 17 of the feed 5, which may correspond approximately to the height of sub-tools of the feed 5 downstream press. Such sub-tools of presses can eg inlet height of 100 mm to 450 mm have; Therefore, it is extremely advantageous for a problem-free transfer of Bandmaterialanfangs in the feed 5, when the straightening machine 6 in the transfer of Bandmaterialanfangs in the feed 5 has the same vertical level as the feed 5 and thus the inlet of the downstream press.

Befindet sich der Bandmaterialanfang hinter den Vorschubrollen des Vorschubs 5 im Erfassungsbereich eines Sensors, werden Richtrollenantriebe gestoppt und anschließend die obere Vorschubrolle durch einen hydraulischen Anstellzylinder abgesenkt. Der Anstelldruck und damit die Anstellkraft der oberen Vorschubrolle wird von einem Schrittmotor, der durch ein Proportionaldruckregelventil gesteuert wird, vorgegeben. Die Einstellwerte werden in einem Werkstückdatenspeicher, üblicherweise für ca. 250.unterschiedliche Werkstücke, gespeichert.If the beginning of the strip material is behind the feed rollers of the feed 5 in the detection range of a sensor, straightening roller drives are stopped and then the upper feed roller is lowered by a hydraulic setting cylinder. The contact pressure and thus the contact force of the upper feed roller is determined by a stepper motor, which is controlled by a proportional pressure control valve. The setting values are stored in a workpiece data memory, usually for about 250.unterschiedliche workpieces, saved.

Durch diese exakt dosierbare Anstellkraft, die mittel seines präzise bei Erreichen eines eingestellten Druckwertes abschaltenden Drucksensors erreicht wird, ist es nicht mehr erforderlich, dass die Bedienungsperson der Bandanlage 1 immer dann, wenn sich die Werkstückbreiten oder Werkstückwerkstoffe ändern, andere Druckwerte manuell eingeben muss; darüber hinaus wird durch die genaue Vorgabe der Anstellkraft Bandschieflauf, der auf zu hohe Anstelldrücke oder auf eine ungenügende Bandmitnahme zurückgeht, die bei zu geringem Anstelldruck auftritt, vermieden.By means of this precisely meterable setting force, which is achieved by means of its pressure sensor which switches off precisely when a set pressure value is reached, it is no longer necessary for the operator of the conveyor system 1 to enter other pressure values manually whenever the workpiece widths or workpiece materials change. In addition, the accurate specification of the contact force band skew, which is due to excessive contact pressures or insufficient tape drive, which occurs at too low Anstelldruck avoided.

Nachdem der Bandmaterialanfang zwischen den Vorschubrollen des Vorschubs 5 fixiert ist, wird seitens der Steuereinheit der Bandanlage veranlasst, dass die Richtmaschine 6 in ihre Richtposition verfahren wird, wobei die genaue Richtposition unter anderem von der Dicke des Bandmaterials 3 abhängt. Die Verfahrung bzw. die Verstellung der Richtmaschine 6 erfolgt durch die Rollenantriebe der Richtmaschine 6; hierbei fördert die Richtmaschine 6 Bandmaterial 3, das in einer Bandschlaufe, die sich zwischen dem Bandauslauf 12 der Richtmaschine 6 und der Einlaufseite 17 des Vorschubs 5 bildet, gespeichert wird. Aus dieser Bandschlaufe entnimmt im weiteren Verfahren der Vorschub 5 das Bandmaterial 3.After the strip material beginning between the feed rollers of the feed 5 is fixed, is caused by the control unit of the belt system that the leveler 6 is moved to its directional position, the exact directional position depends inter alia on the thickness of the strip material 3. The Verfahrung or adjustment of the leveler 6 is carried out by the roller drives the leveler 6; In this case, the leveler 6 promotes strip material 3, which is stored in a belt loop which forms between the strip outlet 12 of the leveler 6 and the inlet side 17 of the feed 5. From this belt loop takes in the further process of the feed 5, the strip material. 3

Die Bedienungsperson der Bandanlage 1 steuert nachfolgend im Einrichtbetrieb den Bandmaterialanfang zum Anschneiden in die Weiterverarbeitungsmaschine. Nachdem einige Vorschubschübe mit jeweilig nachfolgendem Weiterverarbeitungsmaschinenhub getätigt worden sind, wird die Bandanlage 1 auf Automatikbetrieb gestellt.The operator of the conveyor system 1 subsequently controls in Einrichtbetrieb the beginning of the strip material for cutting into the finishing machine. After some feed thrusts with respective subsequent processing engine hub have been made, the belt system 1 is set to automatic mode.

Das Coil 2 wird abgearbeitet, bis ein Bandrest desselben von einem am Bandeinlauf 9 der Richtmaschine 6 angeordneten Bandendesensor erfasst wird.The coil 2 is processed until a remainder of the same is detected by a belt end 9 of the straightening machine 6 arranged belt end.

Für die Verarbeitung des restlichen Bandmaterials 3 ist es vorteilhaft, wenn nach entsprechender Signalisierung des Bandendesensors die Richtmaschine 6 durch ihren horizontalen Positionierantrieb 8, ohne dass sich die Richtrollen der Richtmaschine 6 drehen, mit der Vorschubgeschwindigkeit des Bandmaterials 3 zum Vorschub 5 hin verfahren wird. Bei diesem Verfahren wird eine vergleichsweise flache Bandschlaufe, die der Dicke des Bandmaterials 3 entspricht, gefahren, damit sich der Bandrest nicht unnötig verformt. Der Bandrest fällt dann nicht, wie bei aus dem Stand der Technik bekannten stationären Richtanlagen üblich, auf den Hallenboden oder auf Überleitbrücken, wodurch Oberflächenbeschädigungen und Verschmutzungen auf dem Bandmaterial 3 vermieden werden.For the processing of the remaining strip material 3, it is advantageous if, after appropriate signaling of the belt end sensor, the straightening machine 6 is moved by its horizontal positioning drive 8 without the straightening rollers of the straightening machine 6 rotating with the feed speed of the belt material 3 towards the feed 5. In this method, a comparatively flat belt loop, which corresponds to the thickness of the strip material 3, driven so that the rest of the band does not deform unnecessarily. The rest of the band then does not fall, as is common in stationary dressing systems known from the prior art, onto the hall floor or on transfer bridges, as a result of which surface damage and soiling on the strip material 3 are avoided.

Hierbei wird von einem Vorschubwegaufnehmer die Geschwindigkeit des Bandmaterials 3 an den horizontalen Positionierantrieb 8 bzw. an dessen Steuerung übermittelt. Die Bandgeschwindigkeit ergibt sich aus der Hubzahl je Minute und der Hublänge. Entsprechend fährt die Richtmaschine 6 während der Werkstückproduktion mit Bandgeschwindigkeit in Richtung auf den Vorschub 5.In this case, the speed of the strip material 3 is transmitted to the horizontal positioning drive 8 or to its control by a feed path sensor. The belt speed results from the number of strokes per minute and the stroke length. Accordingly, the straightening machine 6 moves during the workpiece production with belt speed in the direction of the feed. 5

Wenn sich der Bandauslauf 12 der Richtmaschine 6 ca. 1,20 m vor der Einlaufseite 17 des Vorschubs 5 befindet, wird der Transport des Bandmaterialendes durch die horizontale Verfahrung der Richtmaschine 6, ohne dass sich die Rollen der Richtmaschine 6 drehen, durch einen dann betätigten Näherungsschalter unterbrochen. Der Näherungsschalter setzt eine bandeinlaufseitig der Richtmaschine 6 vorgesehene Trennvorrichtung 22 in Betrieb. Mittels dieser Tennvorrichtung 22 wird ein am Bandmaterialende vorgesehener Bandendehaken abgetrennt. Der abgetrennte Bandendehaken fällt - immer an der gleichen Stelle - in einen Schrottbehälter. Dieser Schrottbehälter, bei dem es sich um einen Wagen mit zwei Schrottbehältern handeln kann, kann z.B. rechtwinklig zur Laufrichtung des Bandmaterials 3 aus der Bandanlage 1 herausfahrbar sein.When the belt outlet 12 of the leveler 6 is about 1.20 m in front of the inlet side 17 of the feed 5, the transport of the strip material end by the horizontal Verfahrung the straightening machine 6, without turning the rollers of the leveler 6, interrupted by a then actuated proximity switch. The proximity switch sets a belt inlet side of the straightening machine 6 provided separator 22 in operation. By means of this Tennvorrichtung 22 a provided at the end of the strip material Bandendehaken is separated. The severed Bandendehaken falls - always in the same place - in a scrap container. This scrap container, which may be a car with two scrap containers, can be moved out of the belt system 1 at right angles to the running direction of the strip material 3, for example.

Anschließend übernehmen Hydromotoren, welche die Rollen der Richtmaschine 6 antreiben, automatisch den Weitertransport des gerichteten Bandrestes. Bei jedem Vorschubhub wird diesen Hydromotoren ein Impuls vom Vorschub 5 erteilt. Die Fluidmenge für die Drehzahl und damit die Umlaufgeschwindigkeit der Rollen der Richtmaschine 6, welche der Bandgeschwindigkeit entspricht, wird von einem Proportionalstromregelventil vorgegeben.Subsequently, hydraulic motors, which drive the rollers of the straightening machine 6, automatically take over the further transport of the straightened band remainder. With each feed stroke, these hydraulic motors are given a pulse from the feed 5. The amount of fluid for the speed and thus the rotational speed of the rollers of the leveler 6, which corresponds to the belt speed, is determined by a proportional flow control valve.

Da die meisten Weiterverarbeitungsmaschinen, wie Stanzen und Pressen, Bandmaterial unterschiedlicher Banddicken und hoher Materialfestigkeit verarbeiten können, sollte der Bandendehaken, der nicht durch die Richtmaschine 6 und nicht durch die Weiterverarbeitungsmaschine geführt werden kann, generell abgetrennt werden. Hierzu dient die stromauf der Richtmaschine an deren Bandeinlauf 9 angeordnete Trennvorrichtung 22.Since most finishing machines, such as stamping and pressing, can process strip material of different strip thicknesses and high material strength, the strip end hook, which can not be passed through straightening machine 6 and not through the further processing machine, should generally be severed. For this purpose, the upstream of the straightening machine at the band inlet 9 arranged separator 22 is used.

Die Trennvorrichtung 22 kann als kompakt bauende, hydraulisch betätigte Schere ausgebildet sein, die am Bandeinlauf 9 der Richtmaschine 6 befestigbar ist. Bei dieser Ausführungsform kann der scharnierend aufgehängte Bandüberleittisch 18 am Einlauf der Trennvorrichtung 22 bzw. der Schere gehaltert werden. Die Trennvorrichtung 22 bzw. die Schere kann auch für das Schopfen des Bandmaterialanfangs eingesetzt werden.The separator 22 may be formed as a compact, hydraulically operated scissors, which is fastened to the tape inlet 9 of the leveler 6. In this embodiment can the hinged suspended band transfer table 18 at the inlet of the separator 22 and the scissors are held. The cutting device 22 or the scissors can also be used for the Schopfen the beginning of the strip material.

Darüber hinaus kann die Trennvorrichtung 22 als Trennjäger mit einer mit einer hohen Drehzahl drehenden Trennscheibe ausgestaltet sein. Die Trennscheibe ist mittels eines frequenzgeregelten Getriebemotors profilschienengeführt über einen Kugelspindeltrieb verstellbar, wobei die Verstellrichtung rechtwinklig zur Laufrichtung des Bandmaterials 3 verläuft. Der Trennjäger ist ebenfalls am Bandeinlauf 9 der Richtmaschine 6 angeordnet. Die Verfahrgeschwindigkeit für die Trennscheibe der Trennvorrichtung 22 wird dann je nach Dicke des zu bearbeitenden Bandmaterials 3 im Werkstückdatenspeicher programmiert. Auch bei dieser Ausgestaltung der Trennvorrichtung 22 ist der Bandüberleittisch 18 an der Trennvorrichtung 22 befestigt.In addition, the separating device 22 may be designed as a separating hunter with a rotating at a high speed cutting wheel. The cutting disc is guided by means of a frequency-controlled geared motor profiled rail via a ball screw drive, wherein the adjustment direction is perpendicular to the direction of the strip material 3. The separation hunter is also arranged at the belt inlet 9 of the leveler 6. The travel speed for the cutting wheel of the separating device 22 is then programmed depending on the thickness of the strip material 3 to be processed in the workpiece data memory. Also in this embodiment of the separating device 22, the tape transfer table 18 is attached to the separating device 22.

Des Weiteren ist es möglich, die Trennvorrichtung 22 als Plasma- oder Laserschneidvorrichtung auszugestalten.Furthermore, it is possible to design the separating device 22 as a plasma or laser cutting device.

Aufgrund des Einsatzes der Trennvorrichtung 22 im Bereich des Bandeinlaufs 9 der Richtmaschine 6 ergibt sich eine erhebliche Zeit- und Materialeinsparung.Due to the use of the separating device 22 in the region of the strip inlet 9 of the leveler 6 results in a considerable time and material savings.

Wenn der vorstehend erwähnte Bandendesensor das Bandmaterialende erfasst, erfolgt bei der vorstehend beschriebenen Bandanlage 1 zwangsläufig zunächst die Abtrennung des Bandendehakens mittels der Trennvorrichtung 22. Erst nachdem dieser Vorgang beendet ist, kann der verbleibende Bandrest entsprechend den einzelnen Vorschublängen im Einzelhubbereich aus der Richtmaschine 6 geleitet werden. Die Bedienungsperson wird somit zu der Durchführung des Trennschnitts mittels der Trennvorrichtung 22 gezwungen.When the above-mentioned tape end sensor detects the tape material end, in the tape unit 1 described above, the separation of the tape end hook by means of the separator 22 necessarily begins only after this process is completed, the remaining tape remaining in accordance with the individual feed lengths in Einzelhubbereich the straightening machine 6 are passed. The operator is thus forced to perform the separating cut by means of the separating device 22.

Einlaufseitig des Vorschubs 5 hat die vorstehend geschilderte Bandanlage 1 eine Schneid- und Verbindungsvorrichtung. Ein Schneid- bzw. Verbindungskopf dieser Schneid- und Verbindungsvorrichtung 23 ist in drei Bewegungsrichtungen gezielt verfahrbar, und zwar in Banddurchlaufrichtung, in Bandebene senkrecht zur Banddurchlaufrichtung und vertikal zur Banddurchlaufrichtung.On the inlet side of the feed 5, the above-described conveyor system 1 has a cutting and connecting device. A cutting or connecting head of this cutting and connecting device 23 is selectively movable in three directions of movement, in the tape passage direction, in the belt plane perpendicular to the tape passage direction and vertically to the tape passage direction.

Der Schneid- bzw. Verbindungskopf der Schneid- und verbindungsvorrichtung 23 ist mittels eines Antriebs, der durch einen Servomotor, einen Servoumrichter und eine Kugelrollspindel gebildet ist, in den genannten Richtungen profilschienengeführt verfahrbar.The cutting head of the cutting and connecting device 23 is movable in the rail guided by means of a drive, which is formed by a servo motor, a servo-converter and a ball screw.

Der Schneidvorgang sowie der Verbindungsvorgang kann durch einen Laserschneid- bzw. Laserschweißkopf oder Plasmaschneid- bzw. Plasmaschweißkopf, evtl. der Verbindungsvorgang aber auch durch Clinchen, erfolgen.The cutting process and the bonding process can be done by a laser cutting or laser welding head or plasma cutting or plasma welding head, possibly the connection process but also by clinching.

Das Bandmaterialende wird in Bandlaufrichtung vor dem Vorschub 5 mittels zweier stufenlos verstellbarer, gehärteter und geschliffener Bandseitenführungsleisten 24 geführt. Die Anstellung der beiden Bandseitenführungsleisten 24 erfolgt über ein Handrad mit Bandbreitenanzeige mittels eines rechten bzw. linken Gewindespindeltriebs.The strip material end is guided in the strip running direction before the feed 5 by means of two continuously adjustable, hardened and ground strip side guide strips 24. The employment of the two band side guide rails 24 via a handwheel with bandwidth display by means of a right or left threaded spindle drive.

Der Bandrest wird, je nach erforderlicher Vorschublänge, durch den Vorschub 5 positioniert. Die Schneidvorrichtung der kombinierten Schneid- und Verbindungsvorrichtung 23 wird X Vorschublängen vor der Mitte der Vorschubrollen 25 vor dem Vorschub 5 positioniert. Bei einer Vorschublänge von 100 mm und X = 2 beträgt der Abstand zwischen der Schneidvorrichtung der Schneid- und Verbindungsvorrichtung 23 zur Mitte des Vorschubs 5 bzw. der Vorschubrollen 25 somit 200 mm.The remaining tape is positioned by the feed 5, depending on the required feed length. The cutting device of combined cutting and connecting device 23 X feed lengths is positioned in front of the center of the feed rollers 25 before the feed 5. With a feed length of 100 mm and X = 2, the distance between the cutting device of the cutting and connecting device 23 to the center of the feed 5 and the feed rollers 25 is thus 200 mm.

Die Schneidvorrichtung schneidet nach vorgegebenen Daten, die im Werkstückspeicher gespeichert sind, in Bandlaufrichtung und in horizontaler, senkrecht zur Bandlaufrichtung verlaufender Richtung den Bandrest ab. Der Schnittverlauf bzw. die Kontur des Schnitts ist so gelegt, dass die später folgenden Verbindungsstellen vom Bandmaterialende des ablaufenden Bandes bzw. Coils 2 und vom Bandmaterialanfang des neuen Bandes bzw. Coils 2 nicht in einem empfindlichen Bereich, wo in der nachgeschalteten Weiterverarbeitungsmaschine kleine Ausschnitte, z.B. kleine Lochungen, geschnitten werden, von einem Stempel der Weiterverarbeitungsmaschine zerstört würden. Nach dem Beschneiden des Bandmaterialendes taktet der Vorschub 5, damit die Bandtrennstelle frei wird, um einen Vorschubhub oder mehrere Vorschubhübe das Bandmaterialende aus dem Trennstellenbereich heraus.The cutting device cuts according to predetermined data, which are stored in the workpiece memory, in the tape running direction and in the horizontal, perpendicular to the direction of tape running direction from the rest of the tape. The cutting profile or the contour of the cut is placed so that the later following connection points from the strip material end of the expiring strip or coil 2 and the beginning of the strip material of the new strip or coil 2 not in a sensitive area, where in the downstream processing machine small sections, eg small holes, to be cut, would be destroyed by a stamp of the finishing machine. After trimming the strip material end, the feed 5 clocks to allow the strip separation point to free one feed stroke or multiple feed strokes of the strip material end out of the separation point region.

Die Richtmaschine 6 mit dem Bandmaterialanfang des neuen Coils 2, der über einen am Bandauslauf 12 der Richtmaschine 6 vorgesehenen scharnierbaren Bandüberleittisch 26 positioniert vorragt, leitet, angetrieben durch den horizontalen Positionierantrieb 8, den Bandmaterialanfang des neuen Coils 2 in die Schneidposition für den Bandmaterialanfang.The straightening machine 6 with the beginning of the strip material of the new coil 2, which protrudes over a provided on the belt outlet 12 of the straightening machine 6 hinged band transfer table 26, passes, driven by the horizontal positioning drive 8, the beginning of the strip material of the new coil 2 in the cutting position for the beginning of the strip material.

Mit der gleichen Kontur in Bandlauf- und einer in Horizontalrichtung rechtwinklig zur Bandlaufrichtung verlaufenden Richtung, in der das Bandmaterialende des vorherigen Coils 2 beschnitten wurde, wird auch der Bandmaterialanfang des neuen Coils 2 beschnitten.With the same contour in Bandlauf- and a horizontal direction perpendicular to the direction of tape running direction, in which the strip material end of the previous coil 2 has been cut, the beginning of the strip material of the new coil 2 is also trimmed.

Bei schmalem Bandmaterial 3 kann es vorkommen, dass der Bandmaterialanfang in der Richtmaschine 6 seitlich versetzt wird. Hierdurch kann durch eine indirekte Anstellung der oberen Richtrollen 27 der Richtmaschine 6 bewirkt werden, dass die oberen Richtrollen 27 der Richtmaschine und auch deren obere Einzugrolle innerhalb weniger Sekunden gelüftet werden, die Laufrichtung des Bandmaterials 3 korrigiert wird und anschließend die oberen Richtrollen 27 der Richtmaschine 6 wieder zugefahren werden.With narrow strip material 3, it may happen that the beginning of the strip material is offset laterally in the straightening machine 6. This can be effected by an indirect employment of the upper straightening rollers 27 of the straightening machine 6 that the upper straightening rollers 27 of the straightening machine and their upper feed roller are aired within a few seconds, the running direction of the strip material 3 is corrected and then the upper straightening rollers 27 of the leveler 6th be closed again.

Falls die oberen Richtrollen 27 der Richtmaschine und die obere Einzugrolle derselben gelüftet werden müssen, halten die Bandvorbiegerollen vor den Einzugrollen der Richtmaschine 6 den Bandmaterialanfang in der Richtmaschine 6, damit das Gewicht der Bandschlaufe das Bandmaterial 3 nicht aus der Richtmaschine 6 herauszieht.If the upper straightening rollers 27 of the straightening machine and the upper feed roller of the same need to be lifted, keep the Bandvorbiegerollen before the feed rollers of the leveler 6 the beginning of the strip material in the leveler 6, so that the weight of the belt loop, the strip material 3 does not pull out of the leveler 6.

Am Bandeinlauf 9 der Richtmaschine und am Bandauslauf 12 derselben sind über Hydromotoren und Wegaufnehmer anstellbare Zentriervorrichtungen 28, 29 vorgesehen, die jeweils mit Bandseitenführungen 30 bzw. 31 ausgerüstet sind. Über einen Tipptasterbetrieb wird die erforderliche Position des Bandmaterials 3 hergestellt. Nach der erfolgten Korrektur des Bandlaufs wird der Bandmaterialanfang, wie vorstehend beschrieben, beschnitten.At the belt inlet 9 of the straightening machine and at the belt outlet 12 of the same are provided via hydraulic motors and displacement sensor adjustable centering devices 28, 29, which are each equipped with band side guides 30 and 31 respectively. The required position of the strip material 3 is produced by way of a touch probe operation. After the correction of the tape run, the beginning of the tape material is trimmed as described above.

Das sich daran anschließende Verbinden des Bandmaterialendes des verbrauchten Coils 2 mit dem Bandmaterialanfang des neuen Coils 2 geschieht in derjenigen Position, in der das Bandmaterialende des verbrauchten Coils 2 nach der Beschneidung desselben vom Vorschub 5 positioniert worden ist.The subsequent joining of the strip material end of the spent coil 2 with the beginning of the strip material of the new Coils 2 takes place in the position in which the strip material end of the spent coil 2 has been positioned by the feed 5 after the circumcision thereof.

Um den Bandmaterialanfang des neuen Coils 2 in die gleiche Position zu bekommen, wird der horizontale Positionierantrieb 8 der Richtmaschine 6 entsprechend angesteuert.In order to get the strip material beginning of the new coil 2 in the same position, the horizontal positioning drive 8 of the leveler 6 is driven accordingly.

Der Bandmaterialanfang des neuen Coils 2 wird bündig vor das Bandmaterialende des verbrauchten Coils 2 positioniert.The beginning of the strip material of the new coil 2 is positioned flush in front of the strip material end of the used coil 2.

Die Verbindung zwischen dem Bandmaterialanfang und dem Bandmaterialende wird gezielt an denjenigen Stellen vorgenommen, wo Schweißpunkte bzw. Heftstellen angebracht werden können, die nicht in demjenigen Bereich positioniert sind, wo in der Weiterverarbeitungsmaschine bzw. im Werkzeug empfindliche Durchbrüche, z.B. Lochungen, mit kleinen Durchmessern, eingebracht werden müssen. Die Verbindung kann auch durch Clinchvorgänge erfolgen.The connection between the beginning of the strip material and the strip material end is made specifically at those locations where welding points or stapling points can be applied which are not positioned in that area where sensitive perforations, for example in the finishing machine or in the tool. Perforations, with small diameters, must be introduced. The connection can also be made by clinching operations.

Danach wird im Einzelhubbetrieb der Vorschub 5 mit jeweils nachfolgendem Weiterverarbeitungsmaschinenhub getaktet, bis die Verbindungsstelle zwischen dem Bandmaterialende und dem Bandmaterialanfang auslaufseitig der Weiterverarbeitungsmaschine durchgelaufen ist. Die Verbindungsstellen müssen nach Durchlauf der Weiterverarbeitungsmaschine aus dem Werkstückbehälter entnommen werden.Thereafter, in the single stroke operation, the feed 5 is clocked with subsequent subsequent processing machine lift until the connection point between the strip material end and the strip material beginning has passed through the downstream processing machine. The joints must be removed after passing through the finishing machine from the workpiece container.
