  • a support bolt that can be inserted into its inner opening and several clamping segments that are vertically movable on its outer circumference and thereby radially expandable.
  • Such coils are wound on spools of winding machines, then bound and removed from the spool and transported to the place of their further processing. To do this, the coils, which often have a weight of over 100 kg even with smaller versions, must be hoisted. Here, as with transport, the coil should be treated as gently as possible so as not to impair the unwinding during subsequent processing. It is particularly difficult to transport coils with a comparatively small diameter of the inner opening because the known devices are generally too large to be able to be inserted into such smaller inner openings of coils. The known lifting devices are also complicated in construction and expensive to manufacture, which is mainly due to the fact that they often serve other purposes in the handling of such coils.

  • the outer diameter of the bell can be larger than the maximum diameter of the clamping segments, because when the device is moved into the coil to be lifted, the clamping segments alone engage the inner opening of the coil. In this position, the locking device for the tensioning segments can then be unlocked against the oem support bolt, so that the tensioning segments fall off and are not spread out outside. When the support pin is subsequently raised, the clamping segments then grip firmly on the inside of the coil opening, the weight of the coil increasing the frictional force between the clamping segments and the coil in a known manner.
  • a particularly useful locking device consists of an axially parallel pin arranged at the head of a jeoen clamping segment, penetrating an opening in the bell, and a releasable locking bolt which engages on the outside of the bell in a catch of the pin. If the device is moved into the coil, the lock is released and the pins are released so that the clamping segments can reach their lowering position.
  • a rotary cap is rotatably and axially immovably mounted on the support bolt above the cover plate of the bell, which has a common locking bolt for the pin of all clamping segments. When handling this common locking bolt, all clamping segments are locked or released at the same time.
  • the head of the clamping segments projects radially outward from their outer friction surfaces.

This angle results from the position of the stops 32 and 33 delimiting the window opening 27 with respect to the pin 29. If the pin 29 lies against the stop 32, as can be seen in FIG. 5, the bolt 28 of the bottom 26 of the rotary cap 25 engages the catch 30 of the pin 29 fastened to the clamping segment 3.

Abstract

Apparatus for the lifting of coils, spools and the like of the type which have an interior opening includes a carrying shaft, guide tracks arranged circumferentially about the carrying shaft, and clamping segments disposed on the guide tracks for movement in a radial and a vertical direction, the clamping segments and guide tracks having a cooperable aperture and a cross shaft accommodated in the aperture such that the cross shaft moves in the aperture during relative movement between the guide tracks and the clamping segments. The carrying shaft has an outer conical surface and the clamping segments have an inner conical surface engaging the outer conical surface on the carrying shaft. A locking device is operable to lock the clamping segments into a radially inwardly disposed position such that when the locking device is released, the clamping segments are extended radially outwardly relative to the carrying shaft as the inner conical surface of the carrying segments slide on the carrying shaft to thereby engage the interior opening.

Description

Die Erfindung richtet sich auf eine Vorrichtung zum Anheben von Coils, Spulen oder dergl. mit einem in deren innere Öffnung einfahrbaren Tragbolzen und mehreren an dessen Außenumfang vertikal beweglich und dabei radial nach außen spreizbar gelagerten Spannsegmenten.The invention is directed to a device for lifting coils, coils or the like. With a support bolt that can be inserted into its inner opening and several clamping segments that are vertically movable on its outer circumference and thereby radially expandable.

Derartige Coils werden auf Spulen von Wickelmaschinen gewickelt, dann gebunden und von oer Spule abgenommen und zum Ort ihrer Weiterverarbeitung transportiert. Hierzu müssen die Coils, die selbst bei kleineren Ausführungen vielfach ein Gewicht von bereits über 100 kg aufweisen, angehooen werden. Hierbei wie beim Transport soll das Coil möglichst schonend behandelt werden, um das Abwickeln bei der späteren Weiterverarbeitung nicht zu beeinträchtigen. Besondere Schwierigkeiten bereitet es, Coils mit vergleichsweise geringem Durchmesser der Innenöffnung zu transportieren, weil die bekannten Vorrichtungen im allgemeinen zu groß sind, um in solche kleineren Innenöffnungen von Coils eingefahren werden zu können. Die bekannten Anhebevorrichtungen sind außerdem kompliziert im Aufbau und aufwendig in ihrer Herstellung, was vornehmlich daher rührt, daß sie vielfach auch gleichzeitig anderen Zwecken bei der Handhabung derartiger Coils dienen.Such coils are wound on spools of winding machines, then bound and removed from the spool and transported to the place of their further processing. To do this, the coils, which often have a weight of over 100 kg even with smaller versions, must be hoisted. Here, as with transport, the coil should be treated as gently as possible so as not to impair the unwinding during subsequent processing. It is particularly difficult to transport coils with a comparatively small diameter of the inner opening because the known devices are generally too large to be able to be inserted into such smaller inner openings of coils. The known lifting devices are also complicated in construction and expensive to manufacture, which is mainly due to the fact that they often serve other purposes in the handling of such coils.

Es bestent desnalb das bedürfnis nach oer Konstruktion einer Vorrichtung der eingangs bezeicnneten Art, die einfach im Auf-Dau, wirkungsvoll im Gebrauch und vor allem aucn zur Handhabung von Coils Kleinerer Abmessungen der Innenbonrung geeignet ist. Diesen Aufgaben wird eine Vorrichtung der vorbezeichneten Art gerecnt, bei der an dem Umfang des Tragbolzens für jeoes Spannsegment eine raaial vorstehende achsparallele Führungsscniene angeoranet ist, die in einen Längsführungsschlitz des Spannsegments eingreift und wenigstens einen tangential verlaufenoen Querbolzen trägt, der ein scnräg zur Längsachse angeordnetes Langiocn in dem Spannsegment ourchsetzt, wobei der Tragoolzen einen Außenkonus als Gleitführung für einen Innenkonus der Spannsegmente und die Spannsegmente eine in ihrer radial inneren oberen Stellung wirksame Arretierungseinrichtung gegenüber dem TragDolzen aufweisen.It therefore also meets the need for the construction of a device of the type described at the outset, which is simple in duration, effective in use and, above all, also suitable for handling coils of smaller dimensions for the inner bore. A device of the aforementioned type is calculated for these tasks, in which an axially protruding axially parallel guide rail is anoranet on the circumference of the supporting bolt for jeoes clamping segment, which engages in a longitudinal guide slot of the clamping segment and carries at least one tangential transverse bolt, which has an L arranged obliquely to the longitudinal axis ourchsetzt angiocn in the clamping segment, wherein the Tragoolzen have Olzen effective in its radially inner upper position locking means relative to the supporting D an outer cone as a sliding guide for an inner cone of the collet segments and the clamping segments.

Eine solche Vorricntung besteht praktisch aus lediglich arei Einheiten, dem Tragbolzen, den an diesen gelagerten Spannsegmenten und der Arretierungeinricntung. Sie ist infolgeaessen einfacn uno kostengünstig herzustellen sowie zuverlässig bei ihrer Handhabung, und sie kann dadurch, daß die Spannsegmente unmittelbar um den zentralen Tragbolzen gelagert sind, mit einem außerordentlich kleinen Außendurchmesser der Spannsegmente ausgestaltet werden. Damit kommt sie aber besonders zur Handhabung von Coils mit geringem Durchmesser der Innenöffnung in Betracht.Such a device practically consists only of arei units, the supporting bolt, the clamping segments mounted on these and the locking device. It is consequently simple and inexpensive to manufacture and reliable in its handling, and it can be designed with an extraordinarily small outer diameter of the clamping segments in that the clamping segments are mounted directly around the central supporting bolt. This makes it particularly suitable for handling coils with a small diameter in the inner opening.

In weiterer Ausgestaltung der Erfindung weist der Tragbolzen eine den Kopf der Spannsegmente von oben übergreifende Glocke auf, in die der Kopf der Führungsschiene eingreift und die einen Innenkonus als Gleitführung für einen oberen Außenkonus der Spannsegmente aufweist. Diese Glocke dient der zusätzlichen oberen Führung der Spannsegmente bei inrer SpreizDewegung nach innen, so daß diese nicht nur durch inre Langlöcher geführt sind, sondern sich auch zusätzlich an der GlocKe abstützen.In a further embodiment of the invention, the supporting bolt has a bell which overlaps the head of the clamping segments from above, into which the head of the guide rail engages and which has an inner cone as a sliding guide for an upper outer cone of the clamping segments. This bell is used for the additional upper guidance of the clamping segments in the case of the inner expansion movement inwards so that they are not only led through the inner elongated holes, but are also supported on the bell.

uer Außendurcnmesser der Glocke kann größer sein als dermaximale Durchmesser der Spannsegmente, weil beim Einfahren der Vorrichtung in das anzuhebende Coil allein die Spannsegmente irrdie Innenöffnung des Coils eingreifen. In dieser Stellung kann dann die Arretierungseinricntung für die Spannsegmente gegenüDer oem Tragbolzen entriegelt werden, so daß die Spannsegmente abfallen und nierDei nacn außen verspreizt werden. Beim nachfolgenden Anheben des TragDolzens greifen dann die Spannsegmente fest an der Innenseite der Coilöffnung an, wobei das Gewicht des Coils in bekannter Weise die Reibungskraft zwiscnen Spannsegmenten und Coil erhöht.The outer diameter of the bell can be larger than the maximum diameter of the clamping segments, because when the device is moved into the coil to be lifted, the clamping segments alone engage the inner opening of the coil. In this position, the locking device for the tensioning segments can then be unlocked against the oem support bolt, so that the tensioning segments fall off and are not spread out outside. When the support pin is subsequently raised, the clamping segments then grip firmly on the inside of the coil opening, the weight of the coil increasing the frictional force between the clamping segments and the coil in a known manner.

Nach einem anoeren Merkmal der Erfindung besteht eine besonders zweckmäßige Arretierungseinricntung aus einem am Kopf eines jeoen Spannsegmentes angeordneten, eine Öffnung in der Glocke ourchsetzenden achsparallelen Zapfen sowie einem an der Außenseite der Glocke in eine Raste des Zapfens eingreifenden lösbaren Sperriegel. Ist die Vorrichtung in das Coil eingefahren, wird die Verriegelung gelöst, und die Zapfen werden freigegeben, so daß die Spannsegmente in ihre Absenkstellung gelangen können.According to another feature of the invention, a particularly useful locking device consists of an axially parallel pin arranged at the head of a jeoen clamping segment, penetrating an opening in the bell, and a releasable locking bolt which engages on the outside of the bell in a catch of the pin. If the device is moved into the coil, the lock is released and the pins are released so that the clamping segments can reach their lowering position.

Nach einem weiteren Merkmal der Erfindung ist über der Deckplatte der Glocke eine Drehkappe drehbar und axial unverschiebbar auf dem Tragbolzen gelagert, die einen gemeinsamen Sperriegel für die Zapfen aller Spannsegmente aufweist. Bei der Handhabung dieses gemeinsamen Sperriegels werden gleichzeitig sämtliche Spannsegmente verriegelt bzw. freigegeben.According to a further feature of the invention, a rotary cap is rotatably and axially immovably mounted on the support bolt above the cover plate of the bell, which has a common locking bolt for the pin of all clamping segments. When handling this common locking bolt, all clamping segments are locked or released at the same time.

Es liegt im Rahmen der Erfindung, daß der Kopf der Spannsegmente deren äußere Reibungsflächen radial nach außen überragt. Das hat den Vorteil, daß die Vorrichtung bis zum Aufsitzen dieser Spannsegmentköpfe auf. dem Coil in dieses eingefahren werden kann, worauf dann die Verriegelung für die Spannsegmente gelöst wird. Die Spannsegmente bilden auf diese einfache Weise einen Anschlag, der die Einfahrbewegung in die Vorrichtung in den Coil begrenzt.It is within the scope of the invention that the head of the clamping segments projects radially outward from their outer friction surfaces. This has the advantage that the device remains on until these clamping segment heads are seated. the coil can be retracted into this, whereupon the locking for the clamping segments is released. In this simple manner, the clamping segments form a stop which limits the movement of the device into the coil.

Wie die Erfindung weiter vorsieht, ist bei einer alternativen Ausführungsform der Erfindung zwischen jedem Spannsegment und der zugehörigen Führungsschiene eine Parallelfünrung mit zwei Querbolzen und entsprecnenoen Langlöchern vorgesehen. Durch diese Ausführungsform werden die Spannsegmente doppelt erführt, was eine exakte Führung der Spannsegmente bewirkt.As the invention further provides, in an alternative embodiment of the invention, a parallel guide with two cross bolts and corresponding elongated holes is provided between each clamping segment and the associated guide rail. Through this embodiment, the clamping segments are performed twice, which causes an exact guidance of the clamping segments.

Die Vorrichtung besteht aus einem zentralen Tragpolzen 1, an dessen oberem Ende eine Tragöse 2 befestigt ist, mittels deren die Vorrichtung an einem HeDezeug angeschlagen werden kann. Am unteren Teil des Tragbolzens 1 sind, bei der wiedergegebenen Ausführungsform mit drei Spannsegmenten 3, drei Führungsschienen 4 in achsparalleler Anordnung befestigt, deren Kopf 5 sich in Abstand von der Wandung 6 des Führungsbolzens befindet. Diese Führungsschienen 4 sind in Abstand von 120° um den zentralen Tragbolzen 1 angeordnet. Am unteren Ende 7 des Tragbolzens 1 weist dieser in dem Zwischenraum zwischen den Fünrungsschienen 4 einen Außenkonus 8 auf.The device consists of a central support pole 1, at the upper end of which a support eye 2 is fastened, by means of which the device can be attached to a HeDezeug. On the lower part of the support bolt 1, in the embodiment shown with three clamping segments 3, three guide rails 4 are fastened in an axially parallel arrangement, the head 5 of which is located at a distance from the wall 6 of the guide bolt. These guide rails 4 are arranged at a distance of 120 ° around the central support pin 1. At the lower end 7 of the support bolt 1, this has an outer cone 8 in the space between the guide rails 4.

Jede Führungsschiene 4 dient zur Lagerung eines Spannsegments 3. Hierzu weist der Träger 9 des Spannsegments 3 einen Längsführungsscnlitz 10 auf, der durch das die beiden Teile 11 und 12 des Trägers 9 verbindende Joch 13 überbrückt wird. Der Kopf 14 des Trägers 9 weist ein Langloch 15 auf, aessen Längsachse zum Ende 7 des Tragbolzens 1 hin konvergiert. Das Maß der Konvergenz entspricht dabei dem Steigungswinkel des Konus 8 des Tragbolzens 1. In die Langlöcner 15 der beiden Teile 11 und 12 des Spannsegmentträgers 9 ragen die Enden eines im Kopf 5 der Führungsschiene 4 befestigten Querbolzens 16. Im unteren Ende der Führungsschiene 4 ist ein innenkonus 17 angebracht, der dem Außenkonus 8 des Tragbolzens 1 flächig aufliegt. Die äußere Umfangsfläche 20 des Joches 13 ist in einer dem Steigungswinkel des Konus 8 und dem Konvergenzwinkel der Langlöcher 15 entsprechenden Weise konisch ausgebildet. Dieser Außenkonus 20 liegt dem Innenkonus 21 einer Glocke 22 an, die den Kopf 5 der Führungsschienen 4 und den Kopf 14 der Spannsegmentträger 9 übergreift. Die beiden Konen 20 und 21 bilden eine obere Gleitführung für die Spannsegmente 3 wie die Konen 8 und 17 eine untere Gleitführung gegenüber dem zentralen Tragbolzen 1 darstellen.Each guide rail 4 serves to support a clamping segment 3. For this purpose, the carrier 9 of the clamping segment 3 has a longitudinal guide slot 10, which is bridged by the yoke 13 connecting the two parts 11 and 12 of the carrier 9. The head 1 4 of the carrier 9 has an elongated hole 15, the longitudinal axis of which converges towards the end 7 of the supporting bolt 1. The degree of convergence corresponds to the angle of inclination of the cone 8 of the supporting bolt 1. The ends of a transverse bolt 16 fastened in the head 5 of the guide rail 4 protrude into the elongated holes 15 of the two parts 11 and 12 of the clamping segment carrier 9. In the lower end of the guide rail 4 there is a attached inner cone 17, which lies flat against the outer cone 8 of the supporting bolt 1. The outer peripheral surface 20 of the yoke 13 is conical in a manner corresponding to the pitch angle of the cone 8 and the angle of convergence of the elongated holes 15. This outer cone 20 bears against the inner cone 21 of a bell 22 which engages over the head 5 of the guide rails 4 and the head 14 of the clamping segment carrier 9. The two cones 20 and 21 form an upper sliding guide for the clamping segments 3 as the cones 8 and 17 represent a lower sliding guide relative to the central support pin 1.

Die Glocke 22 ist im Bereich des oberen Endes des Tragbolzens an diesem befestigt. uber der Deckplatte 23 der Glocke 22 ist drehbar, aber axial unverschiebbar auf dem Stutzen 24 des Tragbolzens 1 eine Drehkappe gelagert. Der Boaen 26 dieser Drehkappe 25 weist im Winkelabstand von 120° je ein Fenster 27 auf, in welches ein Sperriegel 28 eingreift. In die Öffnung 27 ragt ein an dem Joch 20 eines jeden Spannsegments 3 befestigter Zapfen 29, der in seinem Umfang eine Raste 30 aufweist. Diese befindet sich in der Einfahrstellung der Spannsegmente 3 nach Fig. 6 in einer solchen Höne, daß sie mit dem Boden 26 der Drehkappe 25 fluchtet. Die Drehkappe 25 weist eine seitliche Handhabe 31 auf, mittels oeren Hilfe sie um einen Winkel von etwa 30° verschwenkt weroen kann. Dieser Winkel ergibt sich aus der Lage der die Fensteröffnung 27 gegenüber dem Zapfen 29 begrenzenden Anschläge 32 und 33. Liegt der Zapfen 29, wie dies Fig. 5 erkennen läßt, dem Anschlag 32 an, greift der Riegel 28 des Bodens 26 der Drehkappe 25 in die Raste 30 des an dem Spannsegment 3 befestigten Zapfens 29 ein. Wird die Drehkappe 25 derart gegenüber den Stutzen 24 des Tragbolzens 1 verschwenKt, daß der Riegel 28 aus der Raste 30 der einzelnen Zapfen 25 austritt, sind die Zapfen 29 und damit die Träger 9 der Spannsegmente 3 freigegeben, so daß sie in die Stellung nach Fig. 7 abfallen können. Dabei gleitet der Konus 20 des Jochs 13 auf dem Innenkonus 21 der Glocke 22 und der Innenkonus 17 des Trägers 9 auf dem Außenkonus 8 des Tragbolzens 1. Die axiale Länge dieser Bewegung bestimmt sich maximal durch die axiale Länge der Langlöcher 15.The bell 22 is fastened to the support bolt in the region of the upper end thereof. Above the cover plate 23 of the bell 22, a rotary cap is rotatably but axially immovable on the socket 24 of the supporting bolt 1. The boa 26 of this rotary cap 25 has a window 27 at an angular distance of 120 °, in which a locking bolt 28 engages. A pin 29, which is fastened to the yoke 20 of each clamping segment 3 and has a catch 30 in its periphery, projects into the opening 27. This is in the retracted position of the clamping segments 3 according to FIG. 6 in such a tone that it is flush with the bottom 26 of the rotary cap 25. The rotary cap 25 has a lateral handle 31, by means of which it can be pivoted through an angle of approximately 30 °. This angle results from the position of the stops 32 and 33 delimiting the window opening 27 with respect to the pin 29. If the pin 29 lies against the stop 32, as can be seen in FIG. 5, the bolt 28 of the bottom 26 of the rotary cap 25 engages the catch 30 of the pin 29 fastened to the clamping segment 3. If the rotary cap 25 is pivoted relative to the socket 24 of the supporting bolt 1 in such a way that the bolt 28 emerges from the catch 30 of the individual pins 25, the pins 29 and thus the carrier 9 of the clamping segments 3 are released so that they move into the position according to FIG 7 can fall off. The cone 20 of the yoke 13 slides on the inner cone 21 of the bell 22 and the inner cone 17 of the carrier 9 on the outer cone 8 of the support bolt 1. The axial length of this movement is determined at most by the axial length of the elongated holes 15.

Der Träger 9 der Spannsegmente 3 trägt unterhalb des Kopfes 14 je eine kreisbogenförmig gekrümmte Spannbacke 35 mit einem äußeren Reibungsbelag 36, z.B. aus Hartgummi oder dergl.The carrier 9 of the clamping segments 3 carries below the head 14 a circular arc-shaped clamping jaw 35 with an outer friction lining 36, e.g. made of hard rubber or the like

Die Ausführungsform nach den Figuren 8 und 9 unterscheidet sicn dadurch von der vorbeschriebenen Ausbildung, oaß eine jede Führungsscniene 4 des Tragbolzens 1 außer dem oberen Querbolzen 16 einen unteren Querbolzen 37 aufweist, der ein weiteres Langloch 38 in den beiden Teilen 11 und 12 des Trägers 9 des Spannsegments 3 durchsetzt. Außerdem sind die Spannbacken 35 mit dem Reibungsbelag 36 über die Zwischenstücke 37 und 38 mit dem Träger 9 verbunden.The embodiment according to FIGS. 8 and 9 differs from the above-described design, in that each guide rail 4 of the supporting bolt 1 has, in addition to the upper transverse bolt 16, a lower transverse bolt 37 which has a further elongated hole 38 in the two parts 11 and 12 of the carrier 9 of the clamping segment 3 penetrates. In addition, the clamping jaws 35 are connected to the friction lining 36 via the intermediate pieces 37 and 38 with the carrier 9.

Die Figuren 1, 6 und 8 zeigen die Vorrichtung in einer Stellung mit eingefahrenen Spannsegmenten 3. Hierbei sind die Zapfen 29 durch die Riegel 28 im Boden 26 der Drehkappe 25 in ihrer oberen Stellung verriegelt. Die Spannsegmente 3 liegen hierbei auf dem minimalen Umfangskreis. In dieser Stellung wird die Vorrichtung in die innere öffnung 40 eines Coils 41 eingefahren, bis die Stufe 42 des Kopfes 14 des Trägers 9 der Oberfläche 43 des Coils 41 zur Auflage gelangt. In dieser Stellung ist die Arretierungseinrichtung für die Zapfen 29 entlastet, und due Drehkappe 25 kann mittels ihrer Handnabe 31 so weit verschwenkt werden, daß die Riegel 28 die Zapfen 29 freigeoen. Durch das eigene Gewicht fallen dann die Spannsegmente 3 so weit ab, bis ihre Reibungsbeläge 36 an der Innenwand des Coils 40 zur Anlage gelangen. Wird nun die Vorrichtung durch ein an der Tragöse 2 angreifendes Hebezeug angehoben, verharren die Spannsegmente 3 in ihrer unteren Stellung, und die Querbolzen 16 bewegen sich innerhalb der schrägverlaufenden Langlöcher 15 nach oben. Dadurch werden die Spannsegmente 3 an ihren konischen Führungen noch weiter nach außen bewegt und die Angriffskraft der Reibbeläge 36 an dem Coil 40 erhöht, so daß dieses bei weiterem Anheben der Vorrichtung zuverlässig mitgenommen wird.Figures 1, 6 and 8 show the device in a position with retracted clamping segments 3. Here, the pins 29 are locked in their upper position by the bolt 28 in the bottom 26 of the rotary cap 25. The clamping segments 3 lie on the minimum circumferential circle. In this position the device is moved a coil 4 1 in the inner opening 4 0 until the level 42 of the head 14 of the support surface 41 comes to rest 9 43 of the coil. In this position, the locking device for the pin 29 is relieved, and the rotary cap 25 can be pivoted so far by means of its hand hub 31 that the bolts 28 release the pin 29. Due to its own weight, the clamping segments 3 then fall off until their friction linings 36 come to rest on the inner wall of the coil 40. If the device is now raised by a lifting device acting on the lifting eye 2, the clamping segments 3 remain in their lower position, and the cross bolts 16 move upward within the oblique elongated holes 15. As a result, the clamping segments 3 are moved further outward on their conical guides and the engagement force of the friction linings 36 on the coil 40 is increased, so that this is reliably carried along when the device is raised further.

Das Mab der Spreizbewegung der Spannsegmente 3 ergibt sich aus der axialen Länge oer Langlöcher 15 und dem Winkel, um welches die Längsachse dieser Langlöcner 15 gegenüber der mittelachse der Vorrichtung konvergieren.The Mab of the spreading movement of the clamping segments 3 results from the axial length of the elongated holes 15 and the angle by which the longitudinal axis of these elongated holes 15 converge with respect to the central axis of the device.
