- the straightening roller elements By means of the straightening roller elements, the elongate semifinished product is directed, while this is conveyed axially along a horizontal conveying path or horizontal straightening of a roller conveyor line of the straightening machine.
- the straightening roller elements wear out gradually and must therefore be replaced from time to time with new straightening roller elements.
- a change of the straightening roller elements in a product change if another elongated semi-finished product is to be addressed.
- the upright device is opened by the operator-side stator half is displaced in the radial direction sideways towards the operating side with respect to the drive-side stator half.
- the straightening roller elements are displaced laterally along a horizontal displacement plane by means of the operator-side stator half in the direction of the horizontal directional plane of the straightening path of the roller conveyor line.
- the straightening roller elements are gripped by a gripper of a change manipulator of the leveler from above, from the horizontal direction plane upwards in a horizontal plane of change, which has a greater vertical height than the horizontal directional plane or the horizontal displacement plane, and thus removed from the operator-side stator half and in the horizontal changing plane is transported sideways over the operating side half of the rack towards the operating side.
- new straightening roller elements are inserted in the reverse direction in the stand device and the straightening machine can begin their work with new straightening roller elements.
- the object of the invention is a straightening machine for straightening an elongated semi-finished product with straightening rollers, with a conveyor track ausgestaltende roller conveyor, with a straightening roller elements opposite the conveyor line holding stand device comprising a drive-side stator half and a relation to the drive-side stator half displaceable user-side stator half, with a changing device for Changing the straightening roller elements and with an alternating path along which the straightening roller elements are movable for changing, solved, in which the straightening roller elements on the one hand by means of the service side stator half along a first extending in a horizontal displacement plane portion of the alternate path and on the other hand by means of the changing device along another in a horizontal change plane extending portion of the alternating path are movable, wherein the straightening machine dad urch distinguished that the horizontal plane of change in the region of the physical vertical extent of the operating side half of the stand is arranged.
- the horizontal plane of change lies within the vertical extent of the operator-side stator half.
- the operating side half of the frame penetrates the horizontal plane of change physically.
- the straightening machine can be set up even in shallow building halls, the room height for changing devices with Kirmanipulatoren conventional design did not appear suitable.
- alternating path in the sense of the invention describes a path between a working position of the straightening roller elements arranged in the roller table and a provision position arranged outside the stand device.
- the first subsection of the alternating path is arranged between this working position and a transfer position arranged within the upright device, but outside the roller conveyor line.
- the further subsection of the alternating path is arranged between this transfer position and the provisioning position, which is located outside the leveler.
- a straightening roller element is preferably composed of straightening rollers, an associated mounting bushing and other supplements. This means that the straightening rollers are pre-assembled or preassembled on the mounting bushes.
- the straightening rollers here are the actual tools of the straightening machine, which interact with the elongated semi-finished products or the like.
- vertical extent in this case describes the physical height of the stand device, in particular the operator-side stand half of the stand device, which extends substantially perpendicular to the horizontal plane.
- the alternating path is arranged completely within the vertical extension of the operating-side stator half.
- the present horizontal change plane such as the horizontal displacement plane
- the horizontal displacement plane is arranged substantially at the same vertical height, on which, for example, the horizontal conveying path of the roller conveyor line or the horizontal directional plane is located.
- the horizontal displacement plane and the horizontal plane of change can also be arranged vertically offset from each other within a certain frame. As a tolerable measure of this may be indicated when the horizontal displacement plane and the horizontal plane of change are spaced apart by a vertical distance which is less than a diameter of the straightening roller elements. As a rule, the vertical distance is then less than 100 mm, for example.
- the changing device comprises changing hurdles, by means of which the straightening roller elements along the horizontal plane of change as a set of rollers on the upright device sentencewise available.
- the straightening roller elements can be advantageously replaced compactly in a substantially horizontal direction.
- change hurdle in the context of the invention describes any device on which one or preferably as roller set several straightening roller elements can be stored for transport purposes. Often such change hurdles associated with straightening machines are also referred to as cassettes.
- a preferred embodiment provides that the changing device at least one longitudinal transport with a parallel to the conveying path of the straightening machine extending longitudinal support track, wherein the longitudinal transport is at least partially disposed between the drive-side stator half and the user-side stator half. This ensures that the longitudinal transport extends at least in the region of the stand device mainly in the direction of the conveying path.
- the change hurdles of the changing device can thereby extremely easy to cooperate with the stand device, since the straightening roller elements can be passed from the user-side stand half to the respective change hurdle constructive very easy, or vice versa.
- this longitudinal transport is a change hurdle longitudinal transport or a straightening roller element or roller set longitudinal transport.
- longitudinal transport in the context of the invention refers to a device whose main transport direction preferably runs essentially parallel to the conveying path of the roller conveyor line.
- a straightening roller transfer between a change hurdle and the operator-side stand half can be structurally further simplified if the longitudinal support section is at the same or approximately the same vertical height of the horizontal plane of change.
- the longitudinal support section lies approximately at the same vertical height of the horizontal alternating plane.
- a vertical height difference of about 100 mm or less is easily possible.
- the longitudinal support section only has to extend from a single side into the upright device in order to be able to arrange the respective change hurdle in the transfer position between the drive-side upright half and the service-side upright half.
- the longitudinal support section is arranged through the upright device, since the longitudinal transport can thereby be arranged on both sides of the upright device.
- the longitudinal support section is connected on both sides to the stand device.
- an inlet-side longitudinal support section section by means of which a fitted with new straightening roller elements change hurdle between the drive-side stator half and the operator-side stator half can retract horizontally.
- an outlet-side longitudinal support stretch section can be realized, by means of which a change hurdle equipped with used straightening roller elements can be extended horizontally out of the upright device.
- the changing device comprises a transverse transport with a transverse transport path, by means of which the straightening roller elements can be delivered to a longitudinal transport of the changing device.
- the transverse transport by means of the longitudinal transport with the stand device operatively connected, so that the change hurdles can be passed easily between the transverse transport and the stand device.
- the longitudinal support section and the transverse transport path along a horizontal plane are arranged to extend.
- the interchangeable hurdles can be moved mainly along the horizontal plane, so that lifting of the leveling roller elements to a vertical height level beyond the pedestal device can be completely avoided.
- the stand device in particular the operating-side stand half, has a receptacle for receiving a change hurdle, so that the change hurdle along the first section of the Alternating path in the displacement plane sideways to the roller conveyor line is displaced.
- a change hurdle can be provided, bypassing the longitudinal transport, so that the used straightening roller elements can be stored more quickly from the operator-side half of the stand to the change hurdle.
- Particularly space-saving recording can be integrated into the leveler when the recording in the roller conveyor line can be arranged below the conveyor line.
- the object of the invention is also achieved by a method for changing straightening roller elements of a straightening machine for straightening an elongated semi-finished product conveyed along a conveying path of a roller table of the straightening machine, in which the straightening roller elements travel horizontally by means of an operator-side stator half of a stator device holding the straightening roller elements with respect to the conveyor track Displacement plane are shifted sideways out of the roller conveyor line or in the roller conveyor line, and in which the straightening roller elements are provided in a laterally arranged next to the roller transfer line transfer position, wherein the method is characterized in that the straightening roller elements in this transfer position of the operating side stand half a change hurdle or vice versa are handed over, and wherein the change hurdle along a horizontal plane of change in the transfer position hine is moved in or out of the transfer position.
- the present method can be performed with a significantly lower vertical height than heretofore possible, thus increasing the variety of potential job sites where the leveler is installed and can be operated significantly increased.
- the change hurdle is moved along the horizontal change plane between the operator-side stator half and one of the actuator-side stator half opposite, drive-side stator half of the stator device.
- the respective change hurdle can be moved in a structurally particularly simple horizontal manner into the straightening machine or out of the straightening machine.
- the change hurdle is moved in alignment with the conveying path into the transfer position or out of the transfer position, since the change hurdle can thereby also be moved parallel to the longitudinal orientation of the stand device.
- a straightening roller change can be made particularly quickly when the straightening roller elements are exchanged sentence by bit as a set of rollers at the transfer position by means of a change hurdle.
- a particularly advantageous variant of the method provides that the change hurdles is moved when the stand device between the drive-side stator half and the service-side stand half, then the change hurdle is moved by means of the operator-side stand half in the roller conveyor line and placed below the conveyor line, while directed by the straightener an elongated semi-finished becomes.
- the change hurdle remains during production in the straightening machine between the two stator halves and is moved during the straightening roll change together with the service-side stand from the roller conveyor line and then moved parallel to the conveying direction of the straightening machine with the used straightening roller elements from the straightening machine. Subsequently, an already built change hurdle is driven with new straightening roller elements in the leveler and moved together with the service-side stand in roller conveyor line, where the change hurdle during production also remains again. As a result, a change hurdle for receiving used straightening roller elements can be provided particularly quickly on the straightening machine.
- the straightening roller elements are already placed on the change hurdle when the change hurdle is displaced sideways out of the roller conveyor line together with the operator-side stand half.
- the construction of the leveler can be significantly simplified.
- a further time savings can be achieved, whereby the straightening machine is ready for use more quickly.
- Possible concrete variants which are possible in the sense of the invention, could be as follows: With regard to a first variant of a change concept with moveable change hurdles, on the one hand, a suitably mounted change hurdle with new straightening roller elements or mounting bushes / straightening rollers and, on the other hand, an empty change hurdle for receiving the straightening roller elements, which were still in use, parallel to the roller table of the straightening machine in an inlet region, So inlet side, and in an outlet area, ie the outlet side, the straightening machine or its stand device on rails a rail track of the longitudinal transport ready. The operator-side stand half of the stand device moves radially so far until the straightening roller elements are in alignment with the available change hurdles.
- the empty change hurdle With a sufficiently large air gap between lower guide rods and transport rings of the lower mounting bushes of the straightening roller elements in the open stator device of the leveler. Additional threading aids on the stand device in the entry or exit area can in particular align upper guide bars on an upper support of transport rings of lower assembly sockets.
- the distance between the upper guide rods to lower supports in the empty state of the change hurdle corresponds approximately to the distance of the upper and lower bearing surfaces, taking into account the air gap (outstanding stroke) of the exchange hurdle.
- chocks can be lowered with upper mounting bushes until upper transport rings rest on upper guide rods.
- a gripping mechanism of holding elements for holding the mounting bushes on the operating side half of the stand can be solved, and the operating side half of the stand continues to drive until the centering of straightening shafts has moved completely out of the mounting bushing.
- the change hurdle is lowered again to the rails.
- the changing hurdle loaded with the used straightening roller elements now moves backwards out of the open stator device of the straightening machine to its initial position.
- the change hurdle pre-assembled with the straightening rollers moves with the new straightening roller elements into the still open Stand device of the leveler into it.
- the change hurdle is raised.
- the operator-side half of the stand continues to move until the straightening shafts are centered in the new mounting bushings of the new straightening shaft elements.
- the gripping mechanism grabs the mounting bushes and pulls them to the operating side half of the stand.
- the emptied change hurdle is lowered in mm down to rails.
- the upper chocks are raised so that the contact between the transport rings of the upper mounting bushes and the upper guide rods is released.
- the guide rods are only on the lower transport rings.
- the emptied change hurdle can drive backwards out of the open stand device back to its original starting position.
- the gripping mechanism for holding the mounting bushes on the operator-side stand half can be released again.
- the leveler is ready for production again.
- an empty change hurdle for receiving the straightening roller elements to be changed and an already pre-assembled for installation of the new straightening roller elements in the inlet and outlet area of the leveler can be arranged, which then only parallel to the roller conveyor line on the same longitudinal support distance in the opposite sense in the direction drive the open stand device in and out of the straightening machine.
- the change hurdles drive only from one side, ie either from the inlet area or from the outlet area, forth in the open stand device of the leveler and then also proceed on a common substructure or stage transversely to the roller conveyor line be used to position the required change hurdle accordingly.
- straightening machine 1 shown serves for straightening elongated semi-finished products (not shown), such as elongate profiles, carriers, such as high-speed rails, or the like.
- the straightening machine 1 shown is a horizontal roller straightening machine (not separately numbered) of the type CRS® (Compact Roller Straightener).
- the straightening machine 1 comprises a roller conveyor line 3 extending in the longitudinal direction 2 of the straightening machine 1, which defines a conveying path 4 of the straightening machine 1, along which the elongated semi-finished product is conveyed through the straightening machine 1 according to the axial conveying direction 5.
- the straightening machine 1 comprises a plurality of straightening roller elements 6 (numbered only by way of example). These straightening roller elements 6 are held in a known manner in a stand device 7 of the straightening machine 1 in a working position 8 in the roller conveyor line 3, that the elongated semi-finished product is directed in the desired manner when passing through the straightening machine 1.
- the straightening roller elements 6 sit at least in this embodiment of receiving bushes 6A and the actual straightening rollers 6B (see only Figures 2 and 3 ), wherein the straightening rollers 6B directly in operative contact with the elongated semi-finished product and therefore subject to wear. In this respect, there is the need to exchange these straightening roller elements 6 on the straightening machine 1 as a function of wear.
- An exchange of the straightening roller elements 6 can be cumulative or alternatively also depending on an elongate semi-finished product to be straightened, for example if the straightening machine 1 is to be converted to another elongated semi-finished product.
- the roller table line 3 is therefore guided by the straightening roller elements 6 arranged and held one behind the other in the upright device 7, and further on the other hand by an inlet roller table 9, which - seen in the axial conveying direction 5 - is arranged in front of the stand device 7, and by an outlet roller table 10, which - seen in the axial conveying direction 5 - placed behind the upright device 7, given.
- the straightening machine 1 further comprises a drive 15 for driving the individual straightening roller elements 6, which is arranged radially, ie in the radial direction 16, spaced from the upright device 7 and thus laterally next to the upright device 7. Since the drive 15 coupled to the individual straightening roller elements is well known from the prior art, this will not be discussed further.
- the upright device 7 has a drive-side stator half 17 and an operator-side stator half 18.
- the drive-side stator half 17 is in this case arranged substantially stationary with respect to the roller table line 3.
- the operator-side stator half 18 is radially displaceable to the roller conveyor line 3 and thus also arranged to the drive-side stator half 17, so that the stator device 7 in the radial direction 16, ie transverse to the conveyor section 5, can be opened to better replace the straightening roller elements 6 can (cf. Figures 2 and 3 ).
- the number of holding elements 19 on the operating-side stand half 18 (only exemplified, see FIG Figures 2 and 3 ) held or mounted straightening roller elements 6 by means of this operator-side stand half 18 along a horizontal displacement plane 20 radially to the conveyor section 4 from the roller conveyor line 3 movable out and positioned in a radially adjacent the roller table 3 arranged transfer position 21 into it.
- the straightening machine 3 comprises a changing device 25 for changing the straightening roller elements 6.
- This changing device 25 has at least one longitudinal transport 26, which extends in this embodiment exactly parallel to the conveying path 4 of the leveler 1.
- This longitudinal transport 26 has a parallel to the conveyor section 4 of the leveler 1 extending longitudinal support section 27, which at least when open stand device 7 (see. Figures 2 and 3 ) passes through the stator device 7 passes.
- the longitudinal transport 26 is at least partially disposed between the drive-side stator half 17 and the operator-side stator half 18, at least when the stand device 7 is opened accordingly, so that a change of the straightening roller elements 6 in the sense of the invention can take place.
- the longitudinal support section 27 is formed in this embodiment as a rail track 28.
- the straightening machine 1 includes changing hurdles 30, on which the straightening roller elements 6 can be discontinued in sets as sets of rollers 31 (only exemplified).
- These change hurdles 30 can advantageously be positioned parallel to the conveying path 4 or the roller conveyor line 3 by means of the longitudinal transport 26 along a horizontal changing plane 32 between the drive-side stator half 17 and the operating-side stator half 18.
- the interaction between the stand device 7 and the change hurdles 30 is structurally simple in that the horizontally extending displacement plane 20 and the horizontally extending change plane 32 lie essentially at the same vertical height 33, the vertical height 33 being shown in FIG FIG. 1 is arranged perpendicular to the sheet plane.
- the present leveler 1 is characterized by an alternating path 35, which has a first section 36 extending in the horizontal displacement plane 20 and which has at least one further section 37 extending in the horizontal plane of change 32.
- the first section 36 of the change path 35 extends here between the working position 8 of the leveler 1 and the transfer position 21 of the leveler 1 and is realized by the radial travel 38 of the operator-side stand half 18.
- the further section 37 of the changing path 35 extends here between the transfer position 21 of the straightening machine 1 and another supply position (not shown here) outside of the straightening machine 1 and is realized by an axial, other travel 39 of the changing device 25 and the longitudinal transport 26 thereof.
- the alternating path 35 more precisely at least the two subsections 36 and 37 of this alternating path 35, extends along a horizontal plane (not separately numbered), preferably the horizontal alternating plane 32, which coincides approximately with the plane of the page.
- the changing device 25 in contrast to the known Krumanipulatoren (not shown) of conventional straightening machines - extremely flat, so that hereby Equipped straightening machines 1 can be installed even in low-building operating buildings.
- the changing device 25 can in this case be made sufficiently flat when the horizontal plane of change 32 extends within the vertical extension 40 of the operating side half 18, as a result, the straightening rollers 6 can be moved in particular parallel to the conveyor section 4 of the leveler 1 by the stator device 7.
- an empty change hurdle 30 is parked by way of example, by means of which, for example, a used roller set 31 can be picked up from used straightening roller elements 6 from the upright device 7.
- a change hurdle 30 with a new set of rollers 31 is arranged on straightening roller elements 6.
- This is a fresh set of rollers 31 arranged in the transfer position 21, which can be used on the leveler 1.
- another example is a change hurdle 30 with a used set of rollers 31 placed on used straightening roller elements 6.
- the change hurdles 30 are retracted only during the straightening roller change in the straightening machine 1, in each case a change hurdle 30 is moved in addition to the inlet and outlet roller table 9 and 10 of the straightening machine 1 parallel to the axial conveying direction 5.
- a change hurdle 30 is moved in addition to the inlet and outlet roller table 9 and 10 of the straightening machine 1 parallel to the axial conveying direction 5.
- the operator-side stator half 18 moves together with the straightening roller elements 6 to be changed transversely to the axial conveying direction 5 out of the roller conveyor line 3.
- an empty change hurdle 30 moves parallel to the roller conveyor line 3 in the raised with respect to the stand device 7 straightening machine 1, takes over the used straightening rollers 6B with the mounting sockets 6A and drives Then back to the starting position on the output side 42 of the transfer position 21.
- the second change hurdle 30 with the already mounted on mounting bushes 6A straightening rollers 6B from the other side, ie input side 41, retract into the straightening machine 1 and the new straightening roller elements 6 to the operator-side stand half 18 handed over. Subsequently, this second change hurdle 30 likewise returns to its previous starting position, that is to say on the input side 41. Finally, the operator-side stand half 18 moves together with the mounting bushes 6A / straightening rollers 6B back into the roller conveyor line 3 and in the working position 8. Thus, the change of the straightening roller elements 6 is constructively and procedurally very simple.
- the straightening roller elements 6 have been transferred in the transfer position 21 of the operator-side stand half 18 to the change hurdle 30 or vice versa, the change hurdle 30 along the horizontal change plane 32 in the transfer position 32 into or out of the transfer position 32 has been moved out.
- the changing device 25 of the leveler 1 is alternatively equipped with a transverse transport 50.
- the transverse transport 50 comprises a transverse support section 51, which is connected to the longitudinal support section 27 of the longitudinal support 26.
- the transverse transport 50 is operatively connected by means of the longitudinal transport 26 with the upright device 7 of the straightening machine 1.
- the transverse support section 51 is at the vertical height 33 of the horizontal plane of change 32, so that a transfer of a change hurdle 30 from the transverse transport 50 to the longitudinal transport 26 or vice versa is easily possible.
- the stand device 7 can also be operated only from a single page.
- the change hurdles 30 are driven only during the actual straightening roller change in the straightening machine 1, but two change hurdles 30 either input side 41 or output side 42 (see. FIG. 1 ) are positioned on a common stage 53 which can be moved in the transverse direction 52 to the longitudinal support section 27 in order to additionally be moved parallel to the conveying path 4 after transfer to the longitudinal transport 26.
- the straightening roller change is basically similar to the first in the FIGS. 1 to 3 shown embodiment, but in which in the FIG. 4 shown further embodiment, the change hurdles 30 either only on the input side 41 (see in particular FIG. 1 ) or only on the output side 42 (see in particular FIG. 1 ) are placed in order to possibly realize the present change concept even in extremely confined spaces.
- the present leveler 1 is still modified to the effect that below the conveyor section 4 and below the working position 8, a receptacle 60 for a change hurdle 30 is present.
- This change hurdle 30 remains during production in the straightening machine 1 between the two stator halves 17 and 18 and is moved at a straightening roller change together with the operator-side stand half 18 from the roller conveyor line 3 and then parallel to a material flow of an elongated semi-finished with used straightening roller elements 6 and used Mounting bushes 6A / straightening rollers 6B moved out of straightening machine 1.
- a vor foundede already with new straightening roller elements 6 change hurdle 30 is driven into the leveler 1 and moved together with the service-side stand 18 in roller conveyor line 3, where the change hurdle 30 remains stationary during production again in the stator device 7.
- a change hurdle 30 for receiving used straightening roller elements 6 can be provided particularly fast on the straightening machine 1.
- the straightening roller elements 6 can at least partially already be deposited on the change hurdle 30, while the change hurdle 30 is displaced sideways out of the roller slide line 3 together with the operator-side stator half 18.

Die Erfindung betrifft einerseits eine Richtmaschine zum Richten eines länglichen Halbzeugs mit Richtrollenelementen, mit einer eine Förderstrecke ausgestaltende Rollgangslinie, mit einer die Richtrollenelemente gegenüber der Förderstrecke haltenden Ständervorrichtung umfassend eine antriebsseitige Ständerhälfte und eine gegenüber der antriebsseitigen Ständerhälfte verlagerbare bedienseitige Ständerhälfte, mit einer Wechselvorrichtung zum Wechseln der Richtrollenelemente und mit einem Wechselpfad, entlang welchem die Richtrollenelemente zum Wechseln bewegbar sind, bei welcher die Richtrollenelemente einerseits mittels der bedienseitigen Ständerhälfte entlang eines ersten sich in einer horizontalen Verlagerungsebene erstreckenden Teilabschnitts des Wechselpfads und andererseits mittels der Wechselvorrichtung entlang eines weiteren sich in einer horizontalen Wechselebene erstreckenden Teilabschnitts des Wechselpfads bewegbar sind.
Die Erfindung betrifft andererseits ein Verfahren zum Wechseln von Richtrollenelementen einer Richtmaschine zum Richten eines entlang einer Förderstrecke einer Rollgangslinie der Richtmaschine geförderten, länglichen Halbzeugs, bei welchem die Richtrollenelemente mittels einer bedienseitigen Ständerhälfte einer die Richtrollenelemente gegenüber der Förderstrecke haltenden Ständervorrichtung entlang einer horizontalen Verlagerungsebene seitwärts aus der Rollgangslinie heraus oder in die Rollgangslinie hinein verlagert werden, und bei welchem die Richtrollenelemente in einer seitlich neben der Rollgangslinie angeordneten Übergabeposition zum Wechseln bereitgestellt werden.The invention relates, on the one hand, to a straightening machine for straightening an elongate semifinished product with straightening roller elements, comprising a roller conveyor line comprising a straightening roller element relative to the conveyor track, comprising a drive-side stator half and an actuator-side stator half displaceable relative to the drive-side stator half, with a changing device for changing the Straightening roller elements and with an alternating path along which the straightening roller elements are movable for changing, in which the straightening roller elements extending on the one hand by means of the service-side stator half along a first extending in a horizontal displacement plane portion of the alternate path and on the other hand by means of the changing device along another extending in a horizontal plane of change Part of the alternate path are movable.
On the other hand, the invention relates to a method for changing straightening roller elements of a straightening machine for straightening a longitudinal semi-finished product conveyed along a conveying path of a roller table of the straightening machine, in which the straightening roller elements move sideways out of the horizontal direction of the straightening roller elements by means of an operating side half of a stator device holding the straightening roller elements Roller rail line or be shifted into the roller conveyor line, and in which the straightening roller elements are provided in a laterally arranged next to the roller table transfer position for changing.
Insbesondere gattungsgemäße Richtmaschinen zum Richten von länglichen Halbzeugen oder dergleichen sind aus dem Stand der Technik hinlänglich bekannt. Diese Richtmaschinen umfassen Werkzeuge, nämlich Richtrollenelemente, welche satzweise in einer Ständervorrichtung der Richtmaschine gehaltert bzw. gelagert sind. Diese Ständervorrichtung umfasst zwei Ständerhälften, eine antriebsseitige Ständerhälfte, welche im Wesentlichen ortsfest an einem Antrieb der Richtrollenelemente angebunden ist, und eine bedienseitige Ständerhälfte, welche gegenüber der antriebsseitigen Ständerhälfte radial zu der Rollgangslinie der Richtmaschine verlagerbar ist, um die Ständervorrichtung zu öffnen.In particular, generic straightening machines for straightening elongated semi-finished products or the like are well known from the prior art. These straightening machines comprise tools, namely straightening roller elements, which are mounted and stored in sets in a stand device of the straightening machine. This stand device comprises two stator halves, a drive-side stator half, which is connected substantially stationary to a drive of the straightening roller elements, and an operator-side stator half, which is opposite to the drive-side stator half radially to the roller table line of the straightener displaceable to open the stator device.
Mittels der Richtrollenelemente wird das längliche Halbzeug gerichtet, während dieses axial entlang einer horizontalen Förderstrecke bzw. horizontalen Richtstrecke einer Rollgangslinie der Richtmaschine gefördert wird. Durch den Kontakt mit dem länglichen Halbzeug während des Richtvorgangs verschleißen die Richtrollenelemente jedoch sukzessive und müssen daher von Zeit zu Zeit gegen neue Richtrollenelemente ausgewechselt werden. Ferner fällt ein Wechsel der Richtrollenelemente bei einem Produktwechsel an, wenn ein anderes längliches Halbzeug gerichtet werden soll.By means of the straightening roller elements, the elongate semifinished product is directed, while this is conveyed axially along a horizontal conveying path or horizontal straightening of a roller conveyor line of the straightening machine. However, due to the contact with the elongated semi-finished product during the straightening process, the straightening roller elements wear out gradually and must therefore be replaced from time to time with new straightening roller elements. Furthermore, a change of the straightening roller elements in a product change, if another elongated semi-finished product is to be addressed.
Zum Auswechseln der Richtrollenelemente wird die Ständervorrichtung geöffnet, indem die bedienseitige Ständerhälfte gegenüber der antriebsseitigen Ständerhälfte in radialer Richtung seitwärts zur Bedienseite hin verlagert wird.To replace the straightening roller elements, the upright device is opened by the operator-side stator half is displaced in the radial direction sideways towards the operating side with respect to the drive-side stator half.
Hierbei werden die Richtrollenelemente mittels der bedienseitigen Ständerhälfte im Wesentlichen in Richtung der horizontalen Richtebene der Richtstrecke der Rollgangslinie seitwärts entlang einer horizontalen Verlagerungsebene verlagert.In this case, the straightening roller elements are displaced laterally along a horizontal displacement plane by means of the operator-side stator half in the direction of the horizontal directional plane of the straightening path of the roller conveyor line.
Anschließend werden die Richtrollenelemente von einem Greifer eines Wechselmanipulators der Richtmaschine von oben gegriffen, aus der horizontalen Richtebene hochwärts in eine horizontale Wechselebene, welche eine größere Vertikalhöhe als die horizontale Richtebene bzw. die horizontale Verlagerungsebene aufweist, angehoben und somit aus der bedienseitigen Ständerhälfte entfernt sowie in der horizontalen Wechselebene seitwärts über die bedienseitige Ständerhälfte hinweg in Richtung Bedienseite abtransportiert. Danach werden neue Richtrollenelemente in umgekehrter Richtung in die Ständervorrichtung eingesetzt und die Richtmaschine kann ihre Arbeit mit neuen Richtrollenelementen aufnehmen.Subsequently, the straightening roller elements are gripped by a gripper of a change manipulator of the leveler from above, from the horizontal direction plane upwards in a horizontal plane of change, which has a greater vertical height than the horizontal directional plane or the horizontal displacement plane, and thus removed from the operator-side stator half and in the horizontal changing plane is transported sideways over the operating side half of the rack towards the operating side. Thereafter, new straightening roller elements are inserted in the reverse direction in the stand device and the straightening machine can begin their work with new straightening roller elements.
Zwar kann insbesondere mit den bekannten Wechselmanipulatoren ein Wechseln der Richtrollenelemente an den Richtmaschinen problemlos vorgenommen werden, jedoch erweist sich das Wechselprozedere mit diesen Wechselmanipulatoren recht aufwändig.Although changing the straightening roller elements on the straightening machines can be carried out without problems, in particular with the known changeover manipulators, the change procedure with these changeover manipulators proves to be rather complicated.
Insbesondere sind die großen unterschiedlichen Vertikalhöhen hinsichtlich der eigentlichen horizontalen Richtebene bzw. horizontalen Verlagerungsebene und der vertikal wesentlich höher liegenden horizontalen Wechselebene von Nachteil, da hierdurch ein in Richtung hochwärts sehr hoch und seitwärts über die bedienseitige Ständerhälfte hinweg bauender Wechselpfad vorgegeben ist. Insofern ist der Wechselpfad nachteilig sehr raumergreifend, so dass diesbezügliche Richtmaschinen meist nur in relativ hohen Hallen bzw. Gebäuden zum Einsatz kommen können.
Der Erfindung liegt die Aufgabe zugrunde, gattungsgemäße Richtmaschinen weiterzuentwickeln, um zumindest die vorgenannten Nachteile überwinden zu können.In particular, the large different vertical heights with respect to the actual horizontal Richtebene or horizontal displacement plane and the vertically much higher lying horizontal plane of change are disadvantageous, as a result in the direction of upwards very high and sideways over the user-side stator half away away building alternating path is given. Insofar is the Wechselpfad adversely very spacious, so that relevant straightening machines can usually be used only in relatively high halls or buildings.
The invention has for its object to further develop generic straightening machines in order to overcome at least the aforementioned disadvantages.
Die Aufgabe der Erfindung wird von einer Richtmaschine zum Richten eines länglichen Halbzeugs mit Richtrollenelementen, mit einer eine Förderstrecke ausgestaltende Rollgangslinie, mit einer die Richtrollenelemente gegenüber der Förderstrecke haltenden Ständervorrichtung umfassend eine antriebsseitige Ständerhälfte und eine gegenüber der antriebsseitigen Ständerhälfte verlagerbare bedienseitige Ständerhälfte, mit einer Wechselvorrichtung zum Wechseln der Richtrollenelemente und mit einem Wechselpfad, entlang welchem die Richtrollenelemente zum Wechseln bewegbar sind, gelöst, bei welcher die Richtrollenelemente einerseits mittels der bedienseitigen Ständerhälfte entlang eines ersten sich in einer horizontalen Verlagerungsebene erstreckenden Teilabschnitts des Wechselpfads und andererseits mittels der Wechselvorrichtung entlang eines weiteren sich in einer horizontalen Wechselebene erstreckenden Teilabschnitts des Wechselpfads bewegbar sind, wobei sich die Richtmaschine dadurch auszeichnet, dass die horizontale Wechselebene im Bereich der körperlichen Vertikalerstreckung der bedienseitigen Ständerhälfte angeordnet ist.The object of the invention is a straightening machine for straightening an elongated semi-finished product with straightening rollers, with a conveyor track ausgestaltende roller conveyor, with a straightening roller elements opposite the conveyor line holding stand device comprising a drive-side stator half and a relation to the drive-side stator half displaceable user-side stator half, with a changing device for Changing the straightening roller elements and with an alternating path along which the straightening roller elements are movable for changing, solved, in which the straightening roller elements on the one hand by means of the service side stator half along a first extending in a horizontal displacement plane portion of the alternate path and on the other hand by means of the changing device along another in a horizontal change plane extending portion of the alternating path are movable, wherein the straightening machine dad urch distinguished that the horizontal plane of change in the region of the physical vertical extent of the operating side half of the stand is arranged.
Dadurch, dass die horizontale Wechselebene im Bereich der körperlichen Vertikalerstreckung der bedienseitigen Ständerhälfte angeordnet ist, baut insbesondere die Wechselvorrichtung wesentlich kompakter als bisher.The fact that the horizontal plane of change is arranged in the region of the physical vertical extension of the operating-side stand half, in particular, the changing device builds much more compact than before.
Mit anderen Worten ausgedrückt: Die horizontale Wechselebene liegt innerhalb der Vertikalerstreckung der bedienseitigen Ständerhälfte.In other words, the horizontal plane of change lies within the vertical extent of the operator-side stator half.
Insofern durchdringt die bedienseitige Ständerhälfte hierbei die horizontale Wechselebene körperlich.In this respect, the operating side half of the frame penetrates the horizontal plane of change physically.
An dieser Stelle sei bereits erwähnt, dass die horizontale Verlagerungsebene und die horizontale Wechselebene nicht zwingend die gleiche Höhenkoordinate hinsichtlich der Vertikalhöhe haben müssen.It should be mentioned at this point that the horizontal displacement plane and the horizontal plane of change do not necessarily have to have the same height coordinate with respect to the vertical height.
Insbesondere wird hierdurch erzielt, dass der weitere Teilabschnitt des Wechselpfads nicht mehr, wie bisher, über die bedienseitige Ständerhälfte verläuft, so dass die Wechselvorrichtung signifikant niedriger baut als bisher üblich.In particular, this achieves the result that the further subsection of the alternating path no longer, as hitherto, runs over the operator-side stator half, so that the interchangeable device builds significantly lower than hitherto usual.
Hierdurch kann die Richtmaschine selbst in flacher bauenden Hallen aufgestellt werden, deren Raumhöhe für Wechselvorrichtungen mit Wechselmanipulatoren herkömmlicher Bauart nicht geeignet erschienen.As a result, the straightening machine can be set up even in shallow building halls, the room height for changing devices with Wechselmanipulatoren conventional design did not appear suitable.
Der Begriff "Wechselpfad" beschreibt im Sinne der Erfindung einen Pfad zwischen einer in der Rollgangslinie angeordneten Arbeitsposition der Richtrollenelemente und einer außerhalb der Ständervorrichtung angeordneten Bereitstellungsposition.The term "alternating path" in the sense of the invention describes a path between a working position of the straightening roller elements arranged in the roller table and a provision position arranged outside the stand device.
Hierbei ist der erste Teilabschnitt des Wechselpfads zwischen dieser Arbeitsposition und einer innerhalb der Ständervorrichtung, aber außerhalb der Rollgangslinie angeordneten Übergabeposition angeordnet.In this case, the first subsection of the alternating path is arranged between this working position and a transfer position arranged within the upright device, but outside the roller conveyor line.
Der weitere Teilabschnitt des Wechselpfads hingegen ist zwischen dieser Übergabeposition und der Bereitstellungsposition angeordnet, welche sich außerhalb der Richtmaschine befindet.The further subsection of the alternating path, however, is arranged between this transfer position and the provisioning position, which is located outside the leveler.
Es versteht sich, dass die auszuwechselnden Richtrollenelemente unterschiedlich ausgestaltet sein können. In der Regel setzt sich ein Richtrollenelement vorzugsweise aus Richtrollen, einer dazugehörigen Montagebuchse und sonstigen Beilagen zusammen. Das bedeutet, dass die Richtrollen auf den Montagebuchsen vorgebaut bzw. vormontiert sind. Die Richtrollen sind hierbei die eigentlichen Werkzeuge der Richtmaschine, welche mit den länglichen Halbzeugen oder dergleichen wechselwirken.It is understood that the straightening roller elements to be replaced can be designed differently. As a rule, a straightening roller element is preferably composed of straightening rollers, an associated mounting bushing and other supplements. This means that the straightening rollers are pre-assembled or preassembled on the mounting bushes. The straightening rollers here are the actual tools of the straightening machine, which interact with the elongated semi-finished products or the like.
Die Begriffe "Verlagerungsebene" und "Wechselebene" beschreiben im Sinne der Erfindung Horizontalebenen, welche im Wesentlichen horizontal verlaufend angeordnet sind.The terms "displacement plane" and "change plane" in the context of the invention describe horizontal planes which are arranged substantially horizontally.
Der Begriff "Vertikalerstreckung" beschreibt vorliegend die körperliche Bauhöhe der Ständervorrichtung, insbesondere der bedienseitigen Ständerhälfte der Ständervorrichtung, welche im Wesentlichen senkrecht zu der Horizontalebene verläuft.The term "vertical extent" in this case describes the physical height of the stand device, in particular the operator-side stand half of the stand device, which extends substantially perpendicular to the horizontal plane.
Um den Wechselpfad horizontal möglichst flach verlaufen zu lassen, ist es vorteilhaft, wenn der Wechselpfad vollständig innerhalb der Vertikalerstreckung der bedienseitigen Ständerhälfte angeordnet ist.In order to allow the alternating path to run as flat as possible horizontally, it is advantageous if the alternating path is arranged completely within the vertical extension of the operating-side stator half.
Das heißt mit anderen Worten, dass die horizontale Wechselebene sich nicht oberhalb der bedienseitigen Ständerhälfte befindet.In other words, that the horizontal plane of change is not above the operating side half of the stand.
In diesem Zusammenhang ist es zweckmäßig, wenn auch die vorliegende horizontale Wechselebene, wie die horizontale Verlagerungsebene, im Wesentlichen auf gleicher Vertikalhöhe angeordnet ist, auf welcher zum Beispiel die horizontale Förderstrecke der Rollgangslinie bzw. die horizontale Richtebene liegt.In this context, it is expedient if the present horizontal change plane, such as the horizontal displacement plane, is arranged substantially at the same vertical height, on which, for example, the horizontal conveying path of the roller conveyor line or the horizontal directional plane is located.
Insofern ist es vorteilhaft, wenn die horizontale Verlagerungsebene und die horizontale Wechselebene auf gleicher Vertikalhöhe angeordnet sind.In this respect, it is advantageous if the horizontal displacement plane and the horizontal plane of change are arranged at the same vertical height.
Es versteht sich, dass die horizontale Verlagerungsebene und die horizontale Wechselebene auch in einem gewissen Rahmen vertikal zueinander versetzt angeordnet sein können. Als ein tolerierbares Maß hierfür kann angegeben sein, wenn die horizontale Verlagerungsebene und die horizontale Wechselebene durch einen Vertikalabstand voneinander beabstandet angeordnet sind, welcher weniger als ein Durchmesser eines der Richtrollenelemente beträgt. In der Regel beträgt hierbei der Vertikalabstand dann beispielsweise weniger als 100 mm.It is understood that the horizontal displacement plane and the horizontal plane of change can also be arranged vertically offset from each other within a certain frame. As a tolerable measure of this may be indicated when the horizontal displacement plane and the horizontal plane of change are spaced apart by a vertical distance which is less than a diameter of the straightening roller elements. As a rule, the vertical distance is then less than 100 mm, for example.
Ferner ist es vorteilhaft, wenn die Wechselvorrichtung Wechselhürden umfasst, mittels welchen die Richtrollenelemente entlang der horizontalen Wechselebene als Rollensatz an der Ständervorrichtung satzweise bereitstellbar sind. Mittels dieser Wechselhürden können die Richtrollenelemente kompakt vorteilhaft im Wesentlichen in horizontaler Richtung ausgewechselt werden.Furthermore, it is advantageous if the changing device comprises changing hurdles, by means of which the straightening roller elements along the horizontal plane of change as a set of rollers on the upright device sentencewise available. By means of these change hurdles, the straightening roller elements can be advantageously replaced compactly in a substantially horizontal direction.
Der Begriff "Wechselhürde" beschreibt im Sinne der Erfindung jegliche Einrichtung, auf welcher zu Transportzwecken eine oder vorzugsweise als Rollensatz mehrere Richtrollenelemente abgelegt werden können. Oftmals sind derartige Wechselhürden im Zusammenhang mit Richtmaschinen auch als Kassetten bezeichnet.The term "change hurdle" in the context of the invention describes any device on which one or preferably as roller set several straightening roller elements can be stored for transport purposes. Often such change hurdles associated with straightening machines are also referred to as cassettes.
Eine bevorzugte Ausführungsvariante sieht vor, dass die Wechselvorrichtung wenigstens einen Längstransport mit einer zu der Förderstrecke der Richtmaschine parallel verlaufenden Längssupportstrecke umfasst, wobei der Längstransport zumindest teilweise zwischen der antriebsseitigen Ständerhälfte und der bedienseitigen Ständerhälfte angeordnet ist. Hierdurch ist sichergestellt, dass der Längstransport zumindest im Bereich der Ständervorrichtung hauptsächlich in Richtung der Förderstrecke verläuft.A preferred embodiment provides that the changing device at least one longitudinal transport with a parallel to the conveying path of the straightening machine extending longitudinal support track, wherein the longitudinal transport is at least partially disposed between the drive-side stator half and the user-side stator half. This ensures that the longitudinal transport extends at least in the region of the stand device mainly in the direction of the conveying path.
Insbesondere die Wechselhürden der Wechselvorrichtung können hierdurch außerordentlich einfach mit der Ständervorrichtung zusammenarbeiten, da die Richtrollenelemente von der bedienseitigen Ständerhälfte an die jeweilige Wechselhürde konstruktiv sehr einfach übergeben werden können, oder vice versa.In particular, the change hurdles of the changing device can thereby extremely easy to cooperate with the stand device, since the straightening roller elements can be passed from the user-side stand half to the respective change hurdle constructive very easy, or vice versa.
Bei diesem Längstransport handelt es sich insofern um einen Wechselhürden-Längstransport oder um einen Richtrollenelemente- bzw. Rollensatz-Längstransport.To this extent, this longitudinal transport is a change hurdle longitudinal transport or a straightening roller element or roller set longitudinal transport.
Der Ausdruck "Längstransport" bezeichnet im Sinne der Erfindung eine Einrichtung, deren Haupttransportrichtung bevorzugt im Wesentlichen parallel zu der Förderstrecke der Rollgangslinie verläuft.The term "longitudinal transport" in the context of the invention refers to a device whose main transport direction preferably runs essentially parallel to the conveying path of the roller conveyor line.
Eine Richtrollenübergabe zwischen einer Wechselhürde und der bedienseitigen Ständerhälfte kann konstruktiv weiter vereinfacht werden, wenn die Längssupportstrecke auf gleicher oder auf annähernd gleicher Vertikalhöhe der horizontalen Wechselebene liegt.A straightening roller transfer between a change hurdle and the operator-side stand half can be structurally further simplified if the longitudinal support section is at the same or approximately the same vertical height of the horizontal plane of change.
Vorliegend sind geringe Vertikalhöhenunterschiede tolerierbar, um die Fertigungskosten hinsichtlich der Wechselvorrichtung gering halten zu können, so dass es vorteilhaft ist, wenn die Längssupportstrecke näherungsweise auf gleicher Vertikalhöhe der horizontalen Wechselebene liegt. Beispielsweise ist ein Vertikalhöhenunterschied von ca. 100 mm oder weniger problemlos möglich.In the present case, small vertical height differences can be tolerated in order to be able to keep the production costs with regard to the changing device low, so that it is advantageous if the longitudinal support section lies approximately at the same vertical height of the horizontal alternating plane. For example, a vertical height difference of about 100 mm or less is easily possible.
Es versteht sich, dass sich die Längssupportstrecke nur von einer einzigen Seite her bis in die Ständervorrichtung hinein erstrecken muss, um die jeweilige Wechselhürde in der Übergabeposition zwischen der antriebsseitigen Ständerhälfte und der bedienseitigen Ständerhälfte anordnen zu können.It is understood that the longitudinal support section only has to extend from a single side into the upright device in order to be able to arrange the respective change hurdle in the transfer position between the drive-side upright half and the service-side upright half.
Besonders zweckmäßig ist es, wenn die Längssupportstrecke durch die Ständervorrichtung hindurch angeordnet ist, da der Längstransport hierdurch beidseits der Ständervorrichtung angeordnet werden kann.It is particularly expedient if the longitudinal support section is arranged through the upright device, since the longitudinal transport can thereby be arranged on both sides of the upright device.
Insofern ist es vorteilhaft, wenn die Längssupportstrecke beidseits an der Ständervorrichtung angeschlossen ist.In this respect, it is advantageous if the longitudinal support section is connected on both sides to the stand device.
Beispielsweise kann hierdurch zum einen ein einlaufseitiger Längssupportstreckenabschnitt realisiert werden, mittels welchem eine mit neuen Richtrollenelementen bestückte Wechselhürde zwischen die antriebsseitige Ständerhälfte und die bedienseitige Ständerhälfte horizontal einfahren kann. Zum anderen kann auch ein auslaufseitiger Längssupportstreckenabschnitt realisiert werden, mittels welchem eine mit gebrauchten Richtrollenelementen bestückte Wechselhürde horizontal aus der Ständervorrichtung ausgefahren werden kann.For example, this can be realized on the one hand, an inlet-side longitudinal support section section, by means of which a fitted with new straightening roller elements change hurdle between the drive-side stator half and the operator-side stator half can retract horizontally. On the other hand, an outlet-side longitudinal support stretch section can be realized, by means of which a change hurdle equipped with used straightening roller elements can be extended horizontally out of the upright device.
Eine alternative Ausführungsvariante sieht vor, dass die Wechselvorrichtung einen Quertransport mit einer Quertransportstrecke umfasst, mittels welchem die Richtrollenelemente einem Längstransport der Wechselvorrichtung zustellbar sind. Hierdurch kann die Bedienung der Ständervorrichtung mit Wechselhürden nur von einer Seite aus erfolgen, wodurch die entsprechend ausgestaltete Vorrichtung insbesondere in Längserstreckung noch kompakter gebaut werden kann.An alternative embodiment provides that the changing device comprises a transverse transport with a transverse transport path, by means of which the straightening roller elements can be delivered to a longitudinal transport of the changing device. As a result, the operation of the stand device with change hurdles can only take place from one side, as a result of which the correspondingly configured device can be made even more compact, especially in the longitudinal direction.
Vorteilhafterweise ist der Quertransport mittels des Längstransports mit der Ständervorrichtung wirkverbunden, so dass die Wechselhürden problemlos zwischen dem Quertransport und der Ständervorrichtung übergeben werden können.Advantageously, the transverse transport by means of the longitudinal transport with the stand device operatively connected, so that the change hurdles can be passed easily between the transverse transport and the stand device.
Liegt die Quersupportstrecke auf der Vertikalhöhe der horizontalen Wechselebene, kann ein im Bereich des Quertransports nochmals in Querrichtung zu der Rollgangslinie der Richtmaschine erweiterter Wechselpfad weiterhin flach ausgestaltet werden.If the transverse support section lies at the vertical height of the horizontal changing plane, an alternative path extended in the region of the transverse transport in the transverse direction to the roller conveyor line of the straightening machine can continue to be flat.
Insofern ist es vorteilhaft, wenn die Längssupportstrecke und die Quertransportstrecke entlang einer Horizontalebene, nämlich bevorzugt entlang der horizontalen Wechselebene, verlaufend angeordnet sind. Hierdurch können die Wechselhürden hauptsächlich entlang der Horizontalebene bewegt werden, dass ein Anheben der Richtrollenelemente auf ein Vertikalhöhenniveau über die Ständervorrichtung hinaus zur Gänze vermieden werden kann.In this respect, it is advantageous if the longitudinal support section and the transverse transport path along a horizontal plane, namely preferably along the horizontal plane of change, are arranged to extend. As a result, the interchangeable hurdles can be moved mainly along the horizontal plane, so that lifting of the leveling roller elements to a vertical height level beyond the pedestal device can be completely avoided.
Bei einer anderen Ausführungsvariante ist vorgesehen, dass die Ständervorrichtung, insbesondere die bedienseitige Ständerhälfte, eine Aufnahme zum Aufnehmen einer Wechselhürde aufweist, so dass die Wechselhürde entlang des ersten Teilabschnitts des Wechselpfads in der Verlagerungsebene seitwärts zu der Rollgangslinie verlagerbar ist. Hierdurch kann bereits unter Umgehung des Längstransports zumindest dahingehend eine Wechselhürde bereitgestellt werden, so dass die gebrauchten Richtrollenelemente schneller von der bedienseitigen Ständerhälfte auf die Wechselhürde abgelegt werden können.In another embodiment, it is provided that the stand device, in particular the operating-side stand half, has a receptacle for receiving a change hurdle, so that the change hurdle along the first section of the Alternating path in the displacement plane sideways to the roller conveyor line is displaced. As a result, at least to this extent, a change hurdle can be provided, bypassing the longitudinal transport, so that the used straightening roller elements can be stored more quickly from the operator-side half of the stand to the change hurdle.
Besonders platzsparend kann die Aufnahme in die Richtmaschine integriert werden, wenn die Aufnahme in der Rollgangslinie unterhalb der Förderstrecke anordenbar ist.Particularly space-saving recording can be integrated into the leveler when the recording in the roller conveyor line can be arranged below the conveyor line.
Die Aufgabe der Erfindung wird auch von einem Verfahren zum Wechseln von Richtrollenelementen einer Richtmaschine zum Richten eines entlang einer Förderstrecke einer Rollgangslinie der Richtmaschine geförderten, länglichen Halbzeugs gelöst, bei welchem die Richtrollenelemente mittels einer bedienseitigen Ständerhälfte einer die Richtrollenelemente gegenüber der Förderstrecke haltenden Ständervorrichtung entlang einer horizontalen Verlagerungsebene seitwärts aus der Rollgangslinie heraus oder in die Rollgangslinie hinein verlagert werden, und bei welchem die Richtrollenelemente in einer seitlich neben der Rollgangslinie angeordneten Übergabeposition zum Wechseln bereitgestellt werden, wobei sich das Verfahren dadurch auszeichnet, dass die Richtrollenelemente in dieser Übergabeposition von der bedienseitigen Ständerhälfte an eine Wechselhürde oder vice versa übergeben werden, und wobei die Wechselhürde entlang einer horizontalen Wechselebene in die Übergabeposition hinein oder aus der Übergabeposition heraus bewegt wird.The object of the invention is also achieved by a method for changing straightening roller elements of a straightening machine for straightening an elongated semi-finished product conveyed along a conveying path of a roller table of the straightening machine, in which the straightening roller elements travel horizontally by means of an operator-side stator half of a stator device holding the straightening roller elements with respect to the conveyor track Displacement plane are shifted sideways out of the roller conveyor line or in the roller conveyor line, and in which the straightening roller elements are provided in a laterally arranged next to the roller transfer line transfer position, wherein the method is characterized in that the straightening roller elements in this transfer position of the operating side stand half a change hurdle or vice versa are handed over, and wherein the change hurdle along a horizontal plane of change in the transfer position hine is moved in or out of the transfer position.
Dadurch, dass die Wechselhürde entlang einer horizontalen Wechselebene in die Übergabeposition hinein oder aus der Übergabeposition heraus bewegt wird, kann das vorliegende Verfahren mit einer signifikant geringeren Vertikalhöhe durchgeführt werden als bisher möglich, wodurch sich die Vielfalt an potentiellen Einsatzorten, an welchen die Richtmaschine aufgestellt und betrieben werden kann, erheblich erhöht.By moving the changeover hurdle into or out of the transfer position along a horizontal change plane, the present method can be performed with a significantly lower vertical height than heretofore possible, thus increasing the variety of potential job sites where the leveler is installed and can be operated significantly increased.
Besonders vorteilhaft ist es, wenn die Wechselhürde entlang der horizontalen Wechselebene zwischen die bedienseitige Ständerhälfte und eine der bedienseitigen Ständerhälfte gegenüberliegende, antriebsseitige Ständerhälfte der Ständervorrichtung bewegt wird. Hierdurch kann die jeweilige Wechselhürde baulich besonders einfach horizontal bis in die Richtmaschine hinein oder aus der Richtmaschine heraus gefahren werden.It is particularly advantageous if the change hurdle is moved along the horizontal change plane between the operator-side stator half and one of the actuator-side stator half opposite, drive-side stator half of the stator device. As a result, the respective change hurdle can be moved in a structurally particularly simple horizontal manner into the straightening machine or out of the straightening machine.
Besonders zweckmäßig ist es, wenn die Wechselhürde fluchten zu der Förderstrecke in die Übergabenposition hinein oder aus der Übergabenposition heraus bewegt wird, da die Wechselhürde hierdurch auch parallel zu der Längsausrichtung der Ständervorrichtung bewegt werden kann.It is particularly expedient if the change hurdle is moved in alignment with the conveying path into the transfer position or out of the transfer position, since the change hurdle can thereby also be moved parallel to the longitudinal orientation of the stand device.
Ein Richtrollenwechsel kann besonders zügig erfolgen, wenn die Richtrollenelemente als Rollensatz an der Übergabeposition mittels einer Wechselhürde satzweise gewechselt werden.A straightening roller change can be made particularly quickly when the straightening roller elements are exchanged sentence by bit as a set of rollers at the transfer position by means of a change hurdle.
Eine besonders vorteilhafte Verfahrensvariante sieht vor, dass die Wechselhürden bei geöffneter Ständervorrichtung zwischen die antriebsseitige Ständerhälfte und die bedienseitige Ständerhälfte bewegt wird, anschließend die Wechselhürde mittels der bedienseitigen Ständerhälfte in die Rollgangslinie verfahren und unterhalb der Förderstrecke platziert wird, während mittels der Richtmaschine ein längliches Halbzeug gerichtet wird.A particularly advantageous variant of the method provides that the change hurdles is moved when the stand device between the drive-side stator half and the service-side stand half, then the change hurdle is moved by means of the operator-side stand half in the roller conveyor line and placed below the conveyor line, while directed by the straightener an elongated semi-finished becomes.
Die Wechselhürde verbleibt während der Produktion in der Richtmaschine zwischen den beiden Ständerhälften und wird beim Richtrollenwechsel zusammen mit dem bedienseitigem Ständer aus der Rollgangslinie verfahren und anschließend parallel zu der Förderrichtung der Richtmaschine mit den gebrauchten Richtrollenelementen aus der Richtmaschine gefahren. Anschließend wird eine bereits vorgebaute Wechselhürde mit neuen Richtrollenelementen in die Richtmaschine gefahren und zusammen mit dem bedienseitigem Ständer in Rollgangslinie verfahren, wo die Wechselhürde während der Produktion auch wieder verbleibt. Hierdurch kann eine Wechselhürde zum Aufnehmen von gebrauchten Richtrollenelementen besonders schnell an der Richtmaschine bereitgestellt werden. In diesem Zusammenhang ist es besonders vorteilhaft, wenn die Richtrollenelemente bereits auf die Wechselhürde abgelegt werden, wenn die Wechselhürde gemeinsam mit der bedienseitigen Ständerhälfte seitwärts aus der Rollgangslinie heraus verlagert wird. Hierbei kann die Konstruktion der Richtmaschine signifikant vereinfacht werden. Ferner kann eine weitere Zeitersparnis erzielt werden, wodurch die Richtmaschine schneller wieder einsatzbereit ist.The change hurdle remains during production in the straightening machine between the two stator halves and is moved during the straightening roll change together with the service-side stand from the roller conveyor line and then moved parallel to the conveying direction of the straightening machine with the used straightening roller elements from the straightening machine. Subsequently, an already built change hurdle is driven with new straightening roller elements in the leveler and moved together with the service-side stand in roller conveyor line, where the change hurdle during production also remains again. As a result, a change hurdle for receiving used straightening roller elements can be provided particularly quickly on the straightening machine. In this context, it is particularly advantageous if the straightening roller elements are already placed on the change hurdle when the change hurdle is displaced sideways out of the roller conveyor line together with the operator-side stand half. In this case, the construction of the leveler can be significantly simplified. Furthermore, a further time savings can be achieved, whereby the straightening machine is ready for use more quickly.
Es versteht sich, dass es auch hinsichtlich dieser Verfahrensvariante möglich ist, die Ständervorrichtung mit zwei Seiten oder nur mit einer Seite an den Längstransport anzuschließen.It is understood that it is also possible with respect to this variant of the method to connect the stand device with two sides or only one side of the longitudinal transport.
Mögliche konkrete Varianten, welche im Sinne der Erfindung möglich sind, könnten wie folgt aussehen:
Hinsichtlich einer ersten Varianten eines Wechselkonzepts mit verfahrbaren Wechselhürden stehen einerseits eine in geeigneter Weise vorgebaute Wechselhürde mit neuen Richtrollenelementen bzw. Montagebuchsen/Richtrollen sowie andererseits eine leere Wechselhürde zur Aufnahme der sich noch zuvor im Einsatz befindlichen Richtrollenelemente parallel zu der Rollgangslinie der Richtmaschine in einem Einlaufbereich, also einlaufseitig, und in einem Auslaufbereich, also auslaufseitig, der Richtmaschine bzw. deren Ständervorrichtung auf Fahrschienen einer Schienenstrecke des Längstransports bereit. Die bedienseitige Ständerhälfte der Ständervorrichtung fährt radial soweit auf, bis sich die Richtrollenelemente in einer Flucht mit den bereitstehenden Wechselhürden befinden. Jetzt fährt die leere Wechselhürde mit einem ausreichend dimensionierten Luftspalt zwischen unteren Führungsstäben und Transportringen der unteren Montagebuchsen der Richtrollenelemente in die geöffnete Ständervorrichtung der Richtmaschine ein. Zusätzliche Einfädelhilfen an der Ständervorrichtung im Ein- oder Auslaufbereich können insbesondere obere Führungsstäbe auf eine obere Auflage von Transportringen von unteren Montagebuchsen ausrichten. Hierbei entspricht der Abstand der oberen Führungsstäbe zu unteren Auflagen im leeren Zustand der Wechselhürde in etwa dem Abstand der oberen und unteren Auflageflächen unter Berücksichtigung des Luftspalts (ausstehender Hub) der Wechselhürde. Nach dem Einfahren der Wechselhürde in die Ständervorrichtung können die Einfädelhilfen beispielsweise händisch entfernt werden. Nun kann die Wechselhürde von den Fahrschienen angehoben werden. Die oberen Führungsstäbe bleiben bevorzugt gelenkig auf der Oberseite der Transportringe der unteren Montagebuchsen liegen. Jetzt können noch Einbaustücke mit oberen Montagebuchsen abgesenkt werden, bis obere Transportringe auf obere Führungsstäbe aufliegen. Ein Greifmechanismus von Halteelementen zum Halten der Montagebuchsen an der bedienseitigen Ständerhälfte kann gelöst werden, und die bedienseitige Ständerhälfte fährt weiter auf, bis die Zentrierung von Richtwellen komplett aus der Montagebuchse gefahren ist. Anschließend wird die Wechselhürde wieder bis auf die Fahrschienen abgesenkt. Die mit den gebrauchten Richtrollenelementen beladene Wechselhürde fährt nun rückwärts aus der geöffneten Ständervorrichtung der Richtmaschine bis auf ihre Anfangsstellung hinaus. Jetzt fährt die mit den Richtrollen vorgebaute Wechselhürde mit den neuen Richtrollenelementen in die weiterhin geöffnete Ständervorrichtung der Richtmaschine hinein. Die Wechselhürde wird angehoben. Die bedienseitige Ständerhälfte fährt weiter zu, bis die Richtwellen in den neuen Montagebuchsen der neuen Richtwellenelemente zentriert sitzen. Der Greifmechanismus packt die Montagebuchsen und zieht diese an die bedienseitige Ständerhälfte heran. Die geleerte Wechselhürde wird mm bis auf Fahrschienen abgesenkt. Die oberen Einbaustücke werden angehoben, so dass der Kontakt zwischen den Transportringen der oberen Montagebuchsen und den oberen Führungsstäben aufgehoben wird. Die Führungsstäbe liegen nur noch auf den unteren Transportringen auf. Nun kann die geleerte Wechselhürde rückwärts aus der geöffneten Ständervorrichtung in ihre ursprüngliche Ausgangsstellung zurück fahren. Jetzt schließt sich die Ständervorrichtung wieder komplett, indem die bedienseitige Ständerhälfte auf die antriebsseitige Ständerhälfte zu fährt. Der Greifmechanismus zum Halten der Montagebuchsen an der bedienseitigen Ständerhälfte kann wieder gelöst werden. Somit ist die Richtmaschine wieder produktionsbereit.Possible concrete variants, which are possible in the sense of the invention, could be as follows:
With regard to a first variant of a change concept with moveable change hurdles, on the one hand, a suitably mounted change hurdle with new straightening roller elements or mounting bushes / straightening rollers and, on the other hand, an empty change hurdle for receiving the straightening roller elements, which were still in use, parallel to the roller table of the straightening machine in an inlet region, So inlet side, and in an outlet area, ie the outlet side, the straightening machine or its stand device on rails a rail track of the longitudinal transport ready. The operator-side stand half of the stand device moves radially so far until the straightening roller elements are in alignment with the available change hurdles. Now moves the empty change hurdle with a sufficiently large air gap between lower guide rods and transport rings of the lower mounting bushes of the straightening roller elements in the open stator device of the leveler. Additional threading aids on the stand device in the entry or exit area can in particular align upper guide bars on an upper support of transport rings of lower assembly sockets. Here, the distance between the upper guide rods to lower supports in the empty state of the change hurdle corresponds approximately to the distance of the upper and lower bearing surfaces, taking into account the air gap (outstanding stroke) of the exchange hurdle. After retracting the change hurdle in the stand device Einfädelhilfen example, can be removed manually. Now the change hurdle can be lifted from the rails. The upper guide rods preferably remain articulated on the top of the transport rings of the lower mounting sockets. Now chocks can be lowered with upper mounting bushes until upper transport rings rest on upper guide rods. A gripping mechanism of holding elements for holding the mounting bushes on the operating side half of the stand can be solved, and the operating side half of the stand continues to drive until the centering of straightening shafts has moved completely out of the mounting bushing. Subsequently, the change hurdle is lowered again to the rails. The changing hurdle loaded with the used straightening roller elements now moves backwards out of the open stator device of the straightening machine to its initial position. Now the change hurdle pre-assembled with the straightening rollers moves with the new straightening roller elements into the still open Stand device of the leveler into it. The change hurdle is raised. The operator-side half of the stand continues to move until the straightening shafts are centered in the new mounting bushings of the new straightening shaft elements. The gripping mechanism grabs the mounting bushes and pulls them to the operating side half of the stand. The emptied change hurdle is lowered in mm down to rails. The upper chocks are raised so that the contact between the transport rings of the upper mounting bushes and the upper guide rods is released. The guide rods are only on the lower transport rings. Now the emptied change hurdle can drive backwards out of the open stand device back to its original starting position. Now the stand device closes completely again, by the operating side half of the stand moves to the drive-side stand half. The gripping mechanism for holding the mounting bushes on the operator-side stand half can be released again. Thus, the leveler is ready for production again.
Bei dieser ersten Variante sind zwei Ausführungsmöglichkeiten denkbar.In this first variant, two design options are conceivable.
Je nach zur Verfügung stehendem Bauraum können eine leere Wechselhürde zur Aufnahme der zu wechselnden Richtrollenelemente und eine bereits vorgebaute zum Einbau der neuen Richtrollenelemente im Ein- und Auslaufbereich der Richtmaschine angeordnet werden, welche dann nur parallel zu der Rollgangslinie auf derselben Längssupportstrecke in umgekehrtem Richtungssinn in die geöffnete Ständervorrichtung der Richtmaschine hinein und wieder hinaus fahren.Depending on the available installation space, an empty change hurdle for receiving the straightening roller elements to be changed and an already pre-assembled for installation of the new straightening roller elements in the inlet and outlet area of the leveler can be arranged, which then only parallel to the roller conveyor line on the same longitudinal support distance in the opposite sense in the direction drive the open stand device in and out of the straightening machine.
Alternativ hierzu ist es auch denkbar, dass die Wechselhürden nur von einer Seite, also entweder von dem Einlaufbereich oder von dem Auslaufbereich, her in die geöffnete Ständervorrichtung der Richtmaschine fahren und zusätzlich dann auch noch auf einer gemeinsamen Unterkonstruktion bzw. Bühne quer zu der Rollgangslinie verfahren werden, um die benötigte Wechselhürde entsprechend zu positionieren.Alternatively, it is also conceivable that the change hurdles drive only from one side, ie either from the inlet area or from the outlet area, forth in the open stand device of the leveler and then also proceed on a common substructure or stage transversely to the roller conveyor line be used to position the required change hurdle accordingly.
Abweichend zu dieser ersten Variante gibt es noch eine Variante mit einem alternativen Wechselkonzepts mit einer zumindest temporär stationär zwischengeparkten Wechselhürde mit der Möglichkeit, dass die Wechselhürde während der Produktion innerhalb der Ständervorrichtung, also innerhalb der Richtmaschine unterhalb der Richtrollenelemente zu belassen. Beim Richtrollenwechsel gleiten diese Richtrollenelemente dann bereits auf die Wechselhürde nach unten, wenn die bedienseitige Ständerhälfte auffährt. Hierbei wird die Wechselhürde mit der bedienseitigen Ständerhälfte gemeinsam querverfahren (Kopplung z.B. über Mitnehmer) und dann analog zu der vorstehend beschriebenen erstens Variante parallel zu der Rollgangslinie aus der geöffneten Ständervorrichtung der Richtmaschine herausgefahren. Eine Klemmung der Montagebuchse an der bedienseitigen Ständerhälfte ist somit im Vergleich zu der ersten Variante nicht zwingend erforderlich, wodurch sich die Konstruktion vereinfacht.
Weitere Merkmale, Effekte und Vorteile vorliegender Erfindung werden anhand anliegender Zeichnung und nachfolgender Beschreibung erläutert, in welchen beispielhaft eine Richtmaschine mit sich innerhalb der Vertikalerstreckung einer bedienseitigen Ständerhälfte einer Ständervorrichtung befindlichen horizontalen Wechselebene dargestellt und beschrieben ist.

Die hinsichtlich eines ersten Ausführungsbeispiels in der
Die Richtmaschine 1 umfasst eine sich in Längserstreckung 2 der Richtmaschine 1 erstreckende Rollgangslinie 3, welche eine Förderstrecke 4 der Richtmaschine 1 definiert, entlang welcher das längliche Halbzeug gemäß der axialen Förderrichtung 5 durch die Richtmaschine 1 hindurch gefördert wird.
Die Richtmaschine 1 umfasst eine Vielzahl an Richtrollenelementen 6 (nur exemplarisch beziffert).
Diese Richtrollenelemente 6 sind in einer an sich bekannten Weise in einer Ständervorrichtung 7 der Richtmaschine 1 derart in einer Arbeitsposition 8 in der Rollgangslinie 3 gehalten, dass das längliche Halbzeug beim Durchlaufen der Richtmaschine 1 in gewünschter Weise gerichtet wird.
Die Richtrollenelemente 6 setzen sich zumindest in diesem Ausführungsbeispiel aus Aufnahmebuchsen 6A und den eigentlichen Richtrollen 6B (siehe nur
Die Rollgangslinie 3 ist einerseits also durch die in der Ständervorrichtung 7 hintereinander angeordneten und gehaltenen Richtrollenelemente 6 und des Weiteren andererseits durch einen Einlaufrollgang 9, welcher - in axialer Förderrichtung 5 gesehen - vor der Ständervorrichtung 7 angeordnet ist, sowie durch einen Auslaufrollgang 10, welcher - in axialer Förderrichtung 5 gesehen - hinter der Ständervorrichtung 7 platziert ist, vorgegeben.
Die Richtmaschine 1 umfasst ferner einen Antrieb 15 zum Antreiben der einzelnen Richtrollenelemente 6, welcher radial, also in radialer Richtung 16, beabstandet von der Ständervorrichtung 7 und damit seitlich neben der Ständervorrichtung 7 angeordnet ist. Da der an den einzelnen Richtrollenelementen gekoppelte Antrieb 15 aus dem Stand der Technik hinlänglich bekannt ist, wird hierauf nicht weiter eingegangen.
Die Ständervorrichtung 7 weist eine antriebsseitige Ständerhälfte 17 und eine bedienseitige Ständerhälfte 18 auf.
Die antriebsseitige Ständerhälfte 17 ist hierbei im Wesentlichen ortsfest bezüglich der Rollgangslinie 3 angeordnet.
Die bedienseitige Ständerhälfte 18 hingegen ist radial verlagerbar zu der Rollgangslinie 3 und damit auch zu der antriebsseitigen Ständerhälfte 17 angeordnet, so dass die Ständervorrichtung 7 in radialer Richtung 16, also quer zu der Förderstrecke 5, geöffnet werden kann, um die Richtrollenelemente 6 besser auswechseln zu können (vgl.
Insofern sind die an der bedienseitigen Ständerhälfte 18 an Halteelemente 19 (nur exemplarisch beziffert, siehe
Darüber hinaus umfasst die Richtmaschine 3 eine Wechselvorrichtung 25 zum Wechseln der Richtrollenelemente 6.
Diese Wechselvorrichtung 25 weist wenigstens einen Längstransport 26 auf, welcher sich in diesem Ausführungsbeispiel genau parallel zu der Förderstrecke 4 der Richtmaschine 1 erstreckt.
Dieser Längstransport 26 weist eine zu der Förderstrecke 4 der Richtmaschine 1 parallel verlaufenden Längssupportstrecke 27 auf, welche zumindest bei geöffneter Ständervorrichtung 7 (vgl.
Die Längssupportstrecke 27 ist in diesem Ausführungsbeispiel als Schienenstrecke 28 ausgebildet.
Des Weiteren umfasst die Richtmaschine 1 Wechselhürden 30, auf welchen die Richtrollenelemente 6 als Rollensätze 31 (nur exemplarisch beziffert) satzweise abgesetzt werden können.
Diese Wechselhürden 30 können mittels des Längstransports 26 entlang einer horizontalen Wechselebene 32 vorteilhalft zwischen die antriebsseitige Ständerhälfte 17 und die bedienseitige Ständerhälfte 18 parallel zu der Förderstrecke 4 bzw. der Rollgangslinie 3 positioniert werden.
Konstruktiv einfach gelingt das Zusammenspiel zwischen der Ständervorrichtung 7 und den Wechselhürden 30 dadurch, dass die horizontal verlaufende Verlagerungsebene 20 und die horizontal verlaufende Wechselebene 32 im Wesentlichen auf gleicher Vertikalhöhe 33 liegen, wobei die Vertikalhöhe 33 gemäß der Darstellung nach der
Insofern zeichnet sich die vorliegende Richtmaschine 1 durch einen Wechselpfad 35 aus, welcher einen sich in der horizontalen Verlagerungsebene 20 erstreckenden, ersten Teilabschnitt 36 und welcher zumindest einen sich in der horizontalen Wechselebene 32 erstreckenden, weiteren Teilabschnitt 37 aufweist.
Der erste Teilabschnitt 36 des Wechselpfades 35 erstreckt sich hierbei zwischen der Arbeitsposition 8 der Richtmaschine 1 und der Übergabeposition 21 der Richtmaschine 1 und ist durch den radialen Verfahrweg 38 der bedienseitigen Ständerhälfte 18 realisiert. Der weitere Teilabschnitt 37 des Wechselpfades 35 erstreckt sich hierbei zwischen der Übergabeposition 21 der Richtmaschine 1 und einer anderen Bereitstellungsposition (hier nicht gezeigt) außerhalb der Richtmaschine 1 und wird durch einen axialen, anderen Verfahrweg 39 der Wechselvorrichtung 25 bzw. des Längstransports 26 hiervon realisiert. Hierbei erstreckt sich der Wechselpfad 35, genauer gesagt zumindest die beiden Teilabschnitte 36 und 37 dieses Wechselpfades 35, entlang einer Horizontalebene (nicht gesondert beziffert), bevorzugt der horizontalen Wechselebene 32, welche beide etwa mit der Blattebene zusammenfällt.
Aufgrund dieses horizontal flach verlaufenden Wechselpfades 35 baut die Wechselvorrichtung 25 - im Gegensatz zu den bekannten Wechselmanipulatoren (nicht gezeigt) herkömmlicher Richtmaschinen - außerordentlich flach, so dass hiermit ausgerüstete Richtmaschinen 1 selbst in niedrig bauenden Betriebsgebäuden aufgestellt werden können.
Die Wechselvorrichtung 25 kann hierbei ausreichend flach gebaut werden, wenn sich die horizontale Wechselebene 32 innerhalb der Vertikalerstreckung 40 der bedienseitigen Ständerhälfte 18 erstreckt, da hierdurch die Richtrollenelemente 6 insbesondere parallel zu der Förderstrecke 4 der Richtmaschine 1 durch die Ständervorrichtung 7 bewegt werden können.
Wie insbesondere aus den
Gemäß der Darstellung nach der
Bei diesem ersten möglichen Ausführungsbeispiel werden die Wechselhürden 30 nur während des Richtrollenwechsels in die Richtmaschine 1 eingefahren, wobei jeweils eine Wechselhürde 30 neben dem Ein- und Auslaufrollgang 9 bzw. 10 der Richtmaschine 1 parallel zu der axialen Förderrichtung 5 verfahren wird.
Zum Richtrollenwechsel fährt die bedienseitige Ständerhälfte 18 gemeinsam mit den zu wechselnden Richtrollenelementen 6 quer zu der axialen Förderrichtung 5 aus der Rollgangslinie 3 hinaus. Anschließend fährt eine leere Wechselhürde 30 parallel zu der Rollgangslinie 3 in die bezüglich der Ständervorrichtung 7 aufgefahrene Richtmaschine 1 ein, übernimmt die gebrauchten Richtrollen 6B mit den Montagebuchsen 6A und fährt wieder zurück in die Ausgangsstellung ausgangsseitig 42 der Übergabeposition 21. Danach kann die zweite Wechselhürde 30 mit den bereits auf Montagebuchsen 6A vorgebauten Richtrollen 6B von der anderen Seite her, also eingangsseitig 41, in die Richtmaschine 1 einfahren und die neuen Richtrollenelemente 6 an die bedienseitige Ständerhälfte 18 übergeben. Anschließend fährt diese zweite Wechselhürde 30 ebenfalls wieder in ihre vorherige Ausgangsstellung, also eingangsseitig 41, zurück. Abschließend fährt die bedienseitige Ständerhälfte 18 zusammen mit den Montagebuchsen 6A/Richtrollen 6B wieder zurück in die Rollgangslinie 3 bzw. in die Arbeitsposition 8. Somit ist der Wechsel der Richtrollenelemente 6 konstruktiv und verfahrenstechnisch sehr einfach durchgeführt.
Insofern sind die Richtrollenelemente 6 in der Übergabeposition 21 von der bedienseitigen Ständerhälfte 18 an die Wechselhürde 30 oder vice versa übergeben worden, wobei die Wechselhürde 30 entlang der horizontalen Wechselebene 32 in die Übergabeposition 32 hinein oder aus der Übergabeposition 32 heraus bewegt wurde.
Bei dem in der
Der Quertransport 50 umfasst eine Quersupportstrecke 51, welche an der Längssupportstrecke 27 des Längssupports 26 angeschlossen ist.
Insofern ist der Quertransport 50 mittels des Längstransports 26 mit der Ständervorrichtung 7 der Richtmaschine 1 wirkverbunden.
Auch bei dem Quertransport 50 befindet sich die Quersupportstrecke 51 auf der Vertikalhöhe 33 der horizontalen Wechselebene 32, so dass eine Übergabe einer Wechselhürde 30 von dem Quertransport 50 zu dem Längstransport 26 oder umgekehrt problemlos möglich ist.
Mittels des Quertransports 50 kann die Ständervorrichtung 7 auch nur von einer einzigen Seite aus bedient werden.
