Description

Die Erfindung betrifft eine Plissiermaschine mit intermittierend angetriebenen Plissierwalzen, zwischen die ein faltbarer Stoff mit Hilfe von an einem oberen und einem unteren Messerbalken angeordneten nach Art von Vorschubzangen arbeitenden Faltmessern einführbar ist, wobei den schwenkbar an den Enden von Auslegern einer um veränderbare Beträge hin- und herschwenkbaren Messerwelle gelagerten Messerbalken Kippvorrichtungen zugeordnet sind.The invention relates to a pleating machine with intermittently driven pleating rollers, between which a foldable material can be inserted with the aid of folding knives arranged in the manner of feed tongs and arranged on an upper and a lower cutter bar, the swiveling at the ends of the outriggers to and fro by variable amounts pivotable knife shaft bearing knife bar tilting devices are assigned.

Bekannt sind Plissiermaschinen der vorstehenden Art, mit denen sich lediglich eine vergleichsweise geringe Zahl von Faltenkombinationen herstellen läßt. Der größte. Teil der Funktionen derartiger Maschinen wird mechanisch gesteuert, wobei eine oder mehrere Steuerwellen Verwendung finden, die mit Nocken versehen sind, welche je nach Art des gewünschten Faltenmusters eingestellt werden müssen. Das Einrichten der bekannten Maschine ist sehr aufwendig und insbesondere in Fällen, in denen nur kleine Aufträge zu erledigen sind, außerordentlich unwirtschaftlich.Pleating machines of the above type are known, with which only a comparatively small number of fold combinations can be produced. The biggest. Part of the functions of such machines is controlled mechanically, one or more control shafts being used which are provided with cams which have to be adjusted depending on the type of the desired fold pattern. Setting up the known machine is very complex and, particularly in cases in which only small orders have to be carried out, is extremely uneconomical.

Der Erfindung liegt die Aufgabe zugrunde, eine Plissiermaschine der in Betracht gezogenen Gattung zu schaffen, bei der alle Funktionen der an der Faltenbildung beteiligten Bauteile mit Hilfe einer elektronischen Programmsteuereinrichtung frei wählbar sind.The invention has for its object to provide a pleating machine of the type under consideration, in which all functions of the components involved in the formation of folds can be freely selected with the aid of an electronic program control device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zum Antrieb der Plissierwalzen, zum Antrieb des Messerbalkens, zum Antrieb der Kippvorrichtung für den oberen Messerbalken und zum Antrieb der Kippvorrichtung für den unteren Messerbalken Einzelantriebe vorgesehen sind, deren Funktionen voneinander unabhängig durch eine elektronische Steuereinrichtung steuerbar sind.This object is achieved in that individual drives are provided for driving the pleating rollers, for driving the cutter bar, for driving the tilting device for the upper cutter bar and for driving the tilting device for the lower cutter bar, the functions of which can be controlled independently of one another by an electronic control device.

Die erfindungsgemässe Plissiermaschine bietet den Vorteil, daß sich mit ihr eine bisher nicht erreichbare Mustervielfalt herstellen läßt. Eine mechanische Umrüstung der Maschine ist nicht mehr erforderlich. Die Arbeitsprogramme lassen sich vielmehr auf internen oder externen Datenträgern speichern und von Fall zu Fall abrufen.The pleating machine according to the invention has the advantage that it can be used to produce a previously unattainable variety of patterns. Mechanical retrofitting of the machine is no longer necessary. The work programs can rather be saved on internal or external data carriers and called up on a case-by-case basis.

Bei Plissiermaschinen, die zusätzlich mit einer Vorrichtung zum Einleiten einer Axialbewegung in die Messerwelle versehen sind, dient auch zur Einleitung der Axialbewegung in die Messerwelle ein weiterer durch die elektronische Steuereinrichtung steuerbarer Einzelantrieb.In the case of pleating machines which are additionally provided with a device for introducing an axial movement into the knife shaft, a further individual drive which can be controlled by the electronic control device also serves to initiate the axial movement into the knife shaft.

Der Aufbau der Vorrichtung zur Einleitung der Axialbewegung sollte dabei übersichtlich sein und auf einfache Weise sowohl eine Veränderung des Axialhubes der Messerwelle als auch je nach Art des gewünschten Musters eine vorübergehende Unterbrechung der Axialbewegungen ermöglichen. Diese Anforderungen sind bei einer Vorrichtung erfüllt, die einen Kugelgewindetrieb aufweist, dessen Gewindespindel durch einen Einzelantrieb mit veränderbarer Drehrichtung antreibbar ist und dessen Gewindehülse mit der Messerwelle verbunden ist.The structure of the device for initiating the axial movement should be clear and allow both a change in the axial stroke of the knife shaft and, depending on the type of the desired pattern, a temporary interruption of the axial movements. These requirements are met in a device which has a ball screw drive, the threaded spindle of which can be driven by an individual drive with a variable direction of rotation, and the threaded sleeve of which is connected to the knife shaft.

Ist die Plissiermaschine darüber hinaus mit einer Vielzahl von relativ zueinander bewegbar an den Messerbalken gelagerten Faltmessersegmenten, d. h. mit einer sogenannten Push-Up-Einrichtung, versehen, so dienen auch zum Bewegen der Faltmessersegmente den einzelnen Segmenten zugeordnete Einzelantriebe, die ebenfalls durch die elektronische Steuereinrichtung steuerbar sind, dabei erweist es sich als besonders zweckmässig, wenn die Faltmessersegmente schwenkbar an den Messerbalken gelagert sind und die Messerbalken Elektromagnete tragen, wobei jedem Faltmessersegment ein Elektromagnet zugeordnet ist. Dadurch, daß die Elektromagnete zusammen mit den Faltmessersegmenten an den Messerbalken gelagert sind, erhält man in diesem Fall Baueinheiten, die bei Bedarf gegen Messerbalken üblicher Art austauschbar sind.If the pleating machine is also equipped with a plurality of folding knife segments which are movably movable relative to one another on the knife bar, i. H. provided with a so-called push-up device, individual drives assigned to the individual segments, which can also be controlled by the electronic control device, also serve to move the folding knife segments, it proves to be particularly expedient if the folding knife segments are pivotably mounted on the cutter bars and the cutter bars carry electromagnets, an electromagnet being assigned to each folding cutter segment. The fact that the electromagnets are mounted together with the folding knife segments on the cutter bars, in this case, structural units are obtained which, if necessary, can be exchanged for conventional cutter bars.

Die dargestellte Maschine besitzt ein Gestell 1 mit zwei Seitenwangen 2 und 3. Die Seitenwangen dienen zur Aufnahme der wichtigsten Teile der Maschine. Zwischen ihnen sind insbesondere zwei Plissierwalzen 4 und 5 gelagert, zwischen die der Stoff mit Hilfe von Faltmessern 6 und 7 einführbar ist, deren Spitze je nach Art der zu bildenden Falten an einem oberen Streifblech 8 oder einem unteren Streifblech 9 entlang geführt werden. Die Faltmesser 6 und 7 sind an Messerbalken 10 und 11 befestigt, die schwenkbar an Auslegern 12 einer Messerwelle 13 gelagert sind. Die Messerbalken 10 und 11 können Kippbewegungen ausführen, um die Messerspitzen entweder am oberen Streifblech 8 oder am unteren Streifblech 9 entlangzuführen bzw. um die Faltmesser zangenartig zu öffnen oder zu schliessen. Zum Einleiten der Kippbewegung in den unteren Messerbalken 11 dient eine an der linken Seite der Maschine angeordnete Kippvorrichtung 14, zum Kippen des oberen Messerbalkens 10 eine an der rechten Seite der Maschine angeordnete Kippvorrichtung 15. In die Messerwelle 13 ist mittels eines Gewindetriebes 16 eine Axialbewegung einleitbar.The machine shown has a frame 1 with two side walls 2 and 3. The side walls serve to hold the most important parts of the machine. Between them, in particular, two pleating rollers 4 and 5 are mounted, between which the fabric can be inserted with the aid of folding knives 6 and 7, the tips of which, depending on the type of folds to be formed, are guided along an upper stripping plate 8 or a lower stripping plate 9. The folding knives 6 and 7 are fastened to knife bars 10 and 11, which are pivotably mounted on arms 12 of a knife shaft 13. The cutter bars 10 and 11 can perform tilting movements around the cutter to lead either along the upper scraper plate 8 or along the lower scraper plate 9 or to open or close the folding knives like pliers. A tilting device 14 arranged on the left side of the machine serves to initiate the tilting movement into the lower cutter bar 11, and a tilting device 15 arranged on the right side of the machine for tilting the upper cutter bar 10. Axial movement can be introduced into the cutter shaft 13 by means of a screw drive 16 .

Wie aus den Figuren erkennbar, ist die Maschine mit fünf von trägheitsarmen Elektromotoren gebildeten Einzelantrieben 17 bis 21 versehen.As can be seen from the figures, the machine is provided with five individual drives 17 to 21 formed by low-inertia electric motors.

Der Einzelantrieb 17 dient zum Antrieb der Plissierwalzen 4 und 5, der Einzelantrieb 18 zum Einleiten einer Schwenkbewegung in die Messerwelle 13, der Einzelantrieb 19 zum Einleiten einer Axialbewegung in die Messerwelle 13 und die Einzelantriebe 20 und 21 zum Antrieb der Kippvorrichtungen 14 und 15. Zur Steuerung der Einzelantriebe 17-21 dient eine elektronische Steuereinrichtung 22.The individual drive 17 is used to drive the pleating rollers 4 and 5, the individual drive 18 to initiate a pivoting movement in the knife shaft 13, the individual drive 19 to initiate an axial movement in the knife shaft 13 and the individual drives 20 and 21 to drive the tilting devices 14 and 15 An electronic control device 22 is used to control the individual drives 17-21.

Einzelheiten von Vorrichtungen zum Einleiten von Axialbewegungen in die Messerwelle 13 ergeben sich aus den Figuren 4 und 5. Man erkennt, daß auf der während des Faltvorganges Hin- und Herbewegungen ausführenden Messerwelle 13 drehbar, jedoch in Axialrichtung gegenüber der Messerwelle 13 nicht verschiebbar, eine Buchse 23 gelagert ist. Diese Buchse 23 trägt eine Platte 24, welche über eine Brücke 25 mit der Gewindehülse 26 in Verbindung steht, die auf der Gewindespindel 27 eines Kugelgewindetriebes gelagert ist. Zum Antrieb der Gewindespindel 27 dient der Einzelantrieb 19, der vorzugsweise von einem trägheitsarmen Scheibenläufermotor gebildet wird.Details of devices for initiating axial movements into the knife shaft 13 can be seen from FIGS. 4 and 5. It can be seen that on the knife shaft 13 which executes back and forth movements during the folding process, a bushing can be rotated, but cannot be displaced in the axial direction with respect to the knife shaft 13 23 is stored. This bushing 23 carries a plate 24 which is connected via a bridge 25 to the threaded sleeve 26 which is mounted on the threaded spindle 27 of a ball screw drive. The individual drive 19, which is preferably formed by a low-inertia disc rotor motor, is used to drive the threaded spindle 27.

Der Einzelantrieb 19 kann um jeweils gewünschte Beträge in die eine oder andere Richtung Drehbewegungen ausführen und dabei über die Gewindehülse 26, die Brücke 25, die Platte 24 und die Buchse 23 Hin- und Herbewegungen in die Messerwelle 13 einleiten, ohne die Schwenkbewegungen der Messerwelle 13 zu behindern.The individual drive 19 can execute rotational movements in one direction or the other in each case by the desired amounts and in the process initiate back and forth movements into the knife shaft 13 via the threaded sleeve 26, the bridge 25, the plate 24 and the bush 23 without the pivoting movements of the knife shaft 13 to hinder.

In Fig. 5 tragen Teile, die Teilen der Fig. 4 entsprechen, die gleichen Bezugszeichen wie in Fig. 4. Bei der Vorrichtung gemäß Fig. 5 fluchten die Achsen der Gewindespindel 28 und der Messerwelle 13, und die Gewindehülse 29 ist mit einem Flansch 30 versehen, der über einen Bolzen 31 fest mit einem Flansch 32 verbunden ist, der drehbar auf einer Hülse 33 gelagert ist, die die Ausleger 12 für die Messerbalken 10 und 11 trägt, die durch die Messerwelle 13 hin- und herschwenkbar sind. Zur Verbindung des Einzelantriebes 19 mit der Gewindespindel 28 dient eine Gelenkkupplung 34, zur Verbindung der Gewindehülse 29 mit der Messerwelle 13 eine von den Flanschen 30 und 32 sowie dem Bolzen 31 gebildete Gabel, die Schwenkbewegungen der Messerwelle 13 mit dem Ausleger 12 zuläßt und letzteren zusammen mit der Messerwelle 13 in Axialrichtung hin- und herverschieben kann. 35 ist ein Drehbewegungen der Gabel verhindernder Führungsbolzen, der in eine Nut 36 des Flansches 30 greift.In FIG. 5, parts which correspond to parts in FIG. 4 have the same reference numerals as in FIG. 4. In the device according to FIG. 5, the axes of the threaded spindle 28 and the cutter shaft 13 are aligned, and the threaded sleeve 29 has a flange 30 provided, which is fixedly connected via a bolt 31 to a flange 32 which is rotatably mounted on a sleeve 33 which carries the arms 12 for the cutter bars 10 and 11 which can be pivoted back and forth by the cutter shaft 13. An articulated coupling 34 is used to connect the individual drive 19 to the threaded spindle 28, and a fork formed by the flanges 30 and 32 and the bolt 31 is used to connect the threaded sleeve 29 to the cutter shaft 13, which allows pivoting movements of the cutter shaft 13 with the boom 12 and the latter together can slide back and forth with the knife shaft 13 in the axial direction. 35 is a rotation movement of the fork-preventing guide pin which engages in a groove 36 of the flange 30.

Die elektronische Steuereinrichtung 22 läßt sich auch dazu nutzen, bei Maschinen mit einer sogenannten Push-Up-Einrichtung zum Betätigen der einzelnen Faltmessersegmente einer derartigen Einrichtung vorgesehene weitere Einzelantriebe zu steuern, welche zweckmässigerweise von Elektromagneten gebildet werden. Wie eine Einrichtung der beschriebenen Art ausgebildet sein kann, ist in den Figuren 6 bis 8 dargestellt.The electronic control device 22 can also be used to control further individual drives provided on machines with a so-called push-up device for actuating the individual folding knife segments of such a device, which drives are expediently formed by electromagnets. How a device of the type described can be designed is shown in FIGS. 6 to 8.

In Fig. 6 sind 37 der obere und 38 der untere Messerbalken einer Plissiermaschine. Die Messerbalken 37 und 38 haben ein im wesentlichen T-förmiges Profil, d. h. sie besitzen jeweils einen Längsbalken 39 und einen Querbalken 40 mit zwei Schenkeln 41 und 42. Im Bereich der freien Enden der Längsbalken 39 und des Schenkels 41 des Querbalkens 40 des T-Profils ist an den Messerbalken 37 und 38 jeweils ein Träger 43 befestigt, der von einer U-Profilschiene gebildet wird. Im Bereich des freien Endes des jeweils anderen Schenkels 42 der Querbalken 40 des T-Profils befinden sich Schwenklager 44 für Faltmessersegmente 45. Die Faltmessersegmente 45 sind als zweiarmige Hebel ausgebildet, die an ihren den Messerbalken 37 bzw. 38 zugewandten Enden Rastanker 46 tragen, welche mit Rastnuten 47 für Raststifte 48 versehen sind (vgl. Fig. 7). Zur Betätigung der an Federn 49 gelagerten Raststifte 48 dienen als Elektromagnete 50 ausgebildete Einzelantriebe, deren Anker 51 auf die Federn 49 einwirken.In Fig. 6, 37 are the upper and 38 the lower cutter bars of a pleating machine. The cutter bars 37 and 38 have a substantially T-shaped profile, i.e. H. they each have a longitudinal bar 39 and a crossbar 40 with two legs 41 and 42. In the area of the free ends of the longitudinal bars 39 and the leg 41 of the crossbar 40 of the T-profile, a support 43 is fastened to the cutter bars 37 and 38, respectively is formed by a U-profile rail. In the area of the free end of the other leg 42 of the crossbeams 40 of the T-profile there are pivot bearings 44 for folding knife segments 45. The folding knife segments 45 are designed as two-armed levers which carry latching anchors 46 on their ends facing the knife bars 37 and 38, respectively are provided with locking grooves 47 for locking pins 48 (see FIG. 7). For actuating the locking pins 48 mounted on springs 49, individual drives designed as electromagnets 50, the armatures 51 of which act on the springs 49.

Wie aus Fig. 8 erkennbar, werden die Federn 49 von Zungen kammartiger Federleisten 52 gebildet.As can be seen from FIG. 8, the springs 49 are formed by tongues of comb-like spring strips 52.

Beim Betrieb der Einrichtung wird durch die Faltmessersegmente 45 ein zu plissierender Stoff zwischen die Plissierwalzen 4 und 5 geführt. Je nach Art der zu bildenden Falten erfolgt die Messerführung längs des oberen Streifbleches 8 oder längs eines unteren Streifbleches 9. Die Messerbalken 37 und 38 führen dabei eine hin-und hergehende Bewegung aus. Beim vorderen walzennahen Totpunkt der Faltmessersegmente 45 werden die Messer geöffnet, d. h. der obere Messerbalken 37 wird in Richtung auf das obere Streifblech 8 und der untere Messerbalken 38 in Richtung auf das untere Streifblech 9 gekippt. Dabei drückt die Vorderkante der oberen Faltmessersegmente gegen das obere Streifblech 8 und die Raststifte 48 rasten in die ihnen zugeordneten Rastlücken 47 der Rastanker 46 ein. Ent-' sprechendes geschieht mit den Faltmessersegmenten 45 des unteren Messerbalkens 38. Während des Rücklaufes der Messerbalken, bei dem die oberen Faltmessersegmente 45 gegen das obere Streifblech 8 und die unteren Faltmessersegmente 45 gegen das untere Streifblech 9 anliegen, werden je nach gewähltem Programm oben und unten Faltmessersegmente 45 entriegelt, wobei jeweils einem entriegelten Faltmessersegment ein verriegeltes Faltmessersegment zugeordnet bleibt. Im hinteren Totpunkt der Messerbalkenbewegung kippt der untere Messerbalken 45 in Richtung des oberen Streifbleches 8 und die mit ihm verriegelten unteren Faltmessersegmente drücken gegen die entriegelten oberen Faltmessersegmente und das obere Streifblech 8. Die auf diese Weise am oberen Streifblech 8 entlanggeführten Faltmessersegmentpaare bilden beim Messervorlauf sogenannte Rückwärtsfalten. Entsprechend kippt der obere Messerbalken 37 in Richtung des unteren Streifbleches 9 und die mit ihm verriegelten oberen Faltmessersegmente 45 drücken folglich gegen die entriegelten unteren Faltmessersegmente 45 des unteren Messerbalkens. Die gegen das untere Streifblech 9 gedrückten Faltmessersegmentpaare formen beim Messervorlauf Vorwärtsfalten. Durch sinnvolle Anordnung der Vor- und Rückwärtsfalten lassen sich plissierte Muster bzw. Bilder bisher nicht bekannter Vielfalt bilden.During operation of the device, a material to be pleated is guided between the pleating rollers 4 and 5 through the folding knife segments 45. Depending on the type of folds to be formed, the knife is guided along the upper scraper plate 8 or along a lower scraper plate 9. The knife bars 37 and 38 execute a reciprocating movement. At the front dead center of the folding knife segments 45 near the roller, the knives are opened, ie the upper knife bar 37 is tilted in the direction of the upper scraper plate 8 and the lower knife bar 38 in the direction of the lower scraper plate 9. The front edge of the upper folding knife segments presses against the upper scraper plate 8 and the locking pins 48 snap into the locking gaps 47 of the locking anchors 46 assigned to them. The same thing happens with the folding knife segments 45 of the lower knife bar 38 . During the return of the knife bar, in which the upper folding knife segments 45 lie against the upper stripping plate 8 and the lower folding knife segments 45 against the lower stripping plate 9, folding knife segments 45 are unlocked at the top and bottom, depending on the program selected, with an unlocked folding knife segment being assigned to each unlocked folding knife segment remains. At the rear dead center of the knife bar movement, the Lower knife bar 45 in the direction of the upper scraper plate 8 and the lower folding knife segments locked with it press against the unlocked upper folding knife segments and the upper scraper plate 8. The folding knife segment pairs guided along the upper scraper plate 8 in this way form so-called reverse folds during the knife advance. Accordingly, the upper cutter bar 37 tilts in the direction of the lower scraper plate 9 and the upper folding knife segments 45 locked with it consequently press against the unlocked lower folding knife segments 45 of the lower cutter bar. The folding knife segment pairs pressed against the lower scraper plate 9 form forward folds during the knife advance. By means of a sensible arrangement of the forward and backward folds, pleated patterns or pictures can be created in a variety not previously known.
