- the corresponding slat securing area for a slat may be disposed within the slat.
- the slat securing portion for a slat may include a head portion adapted to secure the slat against detachment from the device upon failure of the corresponding slat guide portion. This allows the head portion of the slat securing means to catch the slat when the slat detaches from the device and is thrown radially as a result of the centrifugal forces.
- the defect of the slat guide section may be wear or breakage of the slat guide section from the slat guide means.
- the slat guide portion for a slat may include at least one recess adapted to slidably receive the slat for guiding the slat on the slat guide.
- a game between lath and Lattenfiihrungs Superior be provided so that the bar can be slidably received.
- the batten and the slat guide section may be arranged to prevent the slat from detaching from the device during normal operation.
- the slat securing portion may also include a recess which is larger than the recess of the slat guide portion. This allows the slat securing means to catch the slat as the slat detaches from the device. It also prevents the slat and the slat securing means from coming into contact during normal operation of the device, that is, when there is no defect in the slat guide section.
- the slat guide may be made of a first material
- the slat securing means may be made of a second material having a higher hardness and / or abrasion resistance than the first material.
- the first material (Lattenfiihrungsstoff) may be plastic, for example Polyethylene (eg PE 1000) or polyvinylidene fluoride (PVDF).
- the first material may also be another material suitable for guiding the slidable slats.
- the second material (slate securing agent) may be metal, in particular steel.
- the second material may also be another material suitable for securing the slats against detachment of the slats from the device upon failure of the respective slat guide sections.
- the slat guide When the slat guide is made of plastic, it provides a good sliding fit of the slats, that is, a slat - for example made of metal - can slide well on the corresponding slat guide area and thus be guided.
- plastic has a higher wear than, for example, metal. Wear can occur for example due to excessive web tension and a corresponding bending of the geometry or the cross section of the slats.
- the perpendicular may in particular run through the center of the roller (or the axis) and the center of the central support area of the bar.
- the crossbar may be symmetrical in cross section.
- the slat guide portion may include a recess on each side with respect to the vertical.
- the recesses can be essentially in the right Angle (such as 90 ° ⁇ 10 °) to the vertical run.
- the recesses may be adapted to slidably receive the support portions of the slat, which are also substantially perpendicular to the normal, to guide the slat on the slat guide means.
- the holding portions and the recesses are then arranged such that detachment of the bar from the device in the radial direction during normal operation is prevented.
- the roller may comprise a roller body, for example a tube, on which the slats can be guided.
- the roller or the roller base body can be supported by roller bearing means rotatably mounted about the axis.
- the roll bearing means may be located outside of the area of the roll enclosed by the slats (outside the interior of the roll) and / or outside of the fixed part of the apparatus so as to allow easier maintenance or replacement of the roll support means without dismantling the apparatus.
- the slat securing means may be attached to the slat guiding means.
- the lath securing means may also be attached to the roller body.
- the Lattenfiihrungsstoff can be firmly connected to the rotatably mounted about the axis roller body, for example by a screw or pin connection.
- the slat guide means When the slat guide means is disposed at a right angle to the axis, the slat securing means may also be arranged at a right angle to the axis.
- the lattice securing agent may be annular.
- the slat guide may be annular.
- the slat guide means and / or the slat securing means may be closed annular or have at least one slit in the annular form. If both the slat securing means and the slat guide are annular, the slat guide can be slid onto and secured to the roll body and the slat securing means can be slid onto the roll body and attached to the slat guide, or even secured directly to the roll body. This allows the slat securing means to be easily mounted in the device.
- the slats can be continuous.
- the slats may be split, each slat comprising a first slat area and a second slat area in the direction of the axis, wherein the first slat area and the second slat area are slidable relative to each other (split slats).
- the division forms a gap between the first slat region and the second slat region.
- the slat guide may be located a short distance from the gap. This allows the split battens to be optimally supported.
- the roller may comprise at least one protection means for a batten disposed between the first batten region and the second batten region inside the batten, and is adapted to provide a gap between the first batten region and the second batten region in the direction of the axis bridged. It is thus ensured a higher safety of the device during operation. In particular, injuries to the operator can be avoided or reduced by accidental intervention of the operator, for example, with the finger, in the gap between the first and the second lath area and it can also no other items, such as insertion aids (eg straps or ropes) in the Gap.
- insertion aids eg straps or ropes
- the apparatus may comprise at least one slat shifting means for displacing the slats in the direction of the axis, and at least one actuator.
- the actuator may be connected to the slat displacement means by at least one connecting means such that an adjustment of the actuator results in an adjustment of the slat displacement means to offset the at least one resting on the slats web during operation in the direction of the axis.
- the connecting means may be adapted such that the adjustment of the actuator and the adjustment of the slat-displacing means are in a certain relationship to one another.
- the ratio can be variably adjustable. The variable setting of the ratio allows individual adaptation to the particular application of the device. It can thus different strengths or gains of the lateral displacement can be achieved with otherwise the same Actuation of the actuator. In particular, the strength of the lateral displacement can thus be adapted in a simple manner to the type of material web, for example textile web or rubber web.
- the material web can be, for example, a textile web, a paper web, a plastic web or a rubber web, in particular for the production of tires.
- the device can be operated continuously. This has the advantage that the production process is accelerated and thus costs are saved.
- the device can be operated discontinuously, for example with stop intervals for cutting the material web.

- the lath securing portion 23 also includes two notches 23c which are larger than the corresponding notches 21c of the lath guide portion 21. This allows the lath securing means 22 to catch the lath 2 when the lath 2 disengages from the device. It is also prevented that the lath 2 and the lath securing means 22 come into contact during normal operation of the device, that is, when there is no defect of the Lattenfiihrungs Kunststoffes 21.
- the slat guide 20 is made of a first material, such as plastic

- plastic is suitable for guiding the displaceable slats 2 and metal is suitable for securing the slats 2 against detachment of the slats 2 from the device in the event of a defect in the corresponding slat guide regions 21.
- plastic has a higher wear than metal. Wear can occur for example due to excessive web tension and a corresponding bending of the geometry or the cross section of the slats.
- the vertical S is, as in Fig. 2 shown, through the center of the roller 1 (or the axis A) and the center of the central support area 21 a of the bar 2 extending straight line.
- the bar 2 is symmetrical with respect to the vertical S.
- the recesses 21c extend substantially at right angles to the vertical S.
- the recesses 21c are suitable, the holding regions 2c of the crossbar 2 - which are also substantially in the right Angle to the vertical S run - take up slidably to guide the bar 2 on the Lattenfiihrungsstoff 20.
- the holding portions 2c and the recesses 21c are therefore arranged such that detachment of the bar 2 from the device in the radial direction during normal operation is prevented.

- both the slat guide 20 and the slat securing means are disposed at a right angle to the axis A.
- the slat securing means 22 and the slat guide 20 are here annular, either closed annular or having at least one slit in the annular form.
- the slat guide 20 can be slid onto and secured to the roll body 24, and the slat securing means 22 can be slid onto the roll body 24 and attached to the slat guide 20, or even secured directly to the roll body 24. This allows the slat securing means 22 to be easily mounted in the device.
- the slats may be continuous, as in FIG Fig. 1 shown.
- a web guide can be made possible in that the material web is offset laterally and thus there is a change in the positional position of the material web.
- the material web can be guided exactly in this way. It can be a regulation to the center of the web or a regulation by web edge.
- the two ends of the roller can both be connected to a single actuator.
- each slat 2 has a first slat region 31 and a second slat region 32 in the direction of the axis A, the first slat region 31 and the second slat region 32 being displaceable relative to one another.
- the division then creates a gap between the first slat area 31 and the second slat portion 32 formed.

- construction is both a web guide and a Bruausstreifung possible. In Bruausstreifung the web is stretched over its width, for example, to prevent the material web folds wrinkles.
- the two ends of the roller can in this case both be connected to a single actuator, so that the first slat areas 31 and the second slat areas 32 of the slats 2 are displaced by the same actuator.
- the two ends of the roller can also be connected to two different actuators so that the first slat areas 31 and the second slat areas 32 of the slats 2 are displaced independently of each other by different actuators.
- the in the Fig. 6 to 8 shown construction also be used to control the lateral displacement of two webs independently.
- the slat guide 22 and also the slat securing means 22 are arranged at a small distance from the gap. This allows the split battens 2 to be optimally supported.
- Fig. 4 shows a perspective view of a part of the device and Fig. 3 shows a cutaway side view of the device.
- the device shown comprises a slat shifting means 3 for displacing the slats 2 in the direction of the axis A. Furthermore, the device comprises an actuator 4.
- the in Fig. 4 and Fig. 5 The slat shifting means 3 is arranged in the interior of the roller 1, or the steering wheel 7 and the bearing means 6 are in the interior of the roller 1, ie within the space enclosed by the slats 2 space arranged.
- the actuator 4 is connected to the slat-shifting means 3 by a connecting means 5 such that an adjustment of the actuator 4 results in an adjustment of the slat-shifting means 3 to the on the Slats to move 2 lying material web during operation laterally in the direction of the axis A.
- a certain ratio also called adjustment ratio V
- FIG. 4 and Fig. 5 The apparatus shown results in the adjustment of the actuator 4 in a pivoting of the connecting means 3 about a pivot point D relative to a fixed part 10 of the device.
- the ratio is thus defined by a first lever arm between the actuator 4 and the pivot point D and a second lever arm between the pivot point D and the slat shifting means 3.
- This in Fig. 4 and Fig. 5 illustrated connecting means 5 is a pivot lever.
- the pivot lever is connected at one of its ends to the actuator 4 by a hinge 12 and connected at the other end to the slat shifting means 3.
- the slat shifting means 3 comprises for each slat 2 bearing means 6.
- the bearing means 6 is formed in the form of two rollers, so that each bar is slidably mounted in the direction of the axis A.
- the rollers are lightweight castors which have a reduced rolling resistance, so that a low-friction sliding support of the slats is possible.
- the rollers are ball bearings, so that less friction and thus less wear occurs. This is particularly advantageous in a dry environment, such as tire manufacturing.
- the rollers may also be slide-mounted, for example in a wet environment, such as in textile production.
- the rollers have a curved (crowned) tread.
- the slat shifting means 3 further comprises a steering disc 7.
- the connecting means 5 in the form of the pivot lever is fixed with the steering wheel 7 connected.
- the steering disc 7 is - in a starting position - arranged in a plane perpendicular to the axis A, that is, the steering disc 7 forms a right angle with the axis A.
- An adjustment of the steering disc 7 is therefore a pivoting of the steering disc 7 to the axis A, that is, the steering wheel 7 is - either to the right or to the left in the direction of the axis A - placed at an angle less than 90 ° to the axis A.
- the steering disc 7 interacts with the rollers of the slats 2 such that an adjustment of the steering disc 7 results in a displacement of the slats 2 in the direction of the axis.
- the belonging to a bar 2 roles are firmly connected to the bar 2.
- the rollers are arranged on the two sides of the steering wheel 7 in the direction of the axis A, so that the bar 2 is displaceable in the direction of the axis A.
- the displacement of the slat displacement means 3 here is thus a pivoting of the steering disc and a displacement of the rollers in the direction of the axis A.
- rollers on the two sides of the steering disc 7 By providing the rollers on the two sides of the steering disc 7 is allowed that the rollers do not have to be braked when the direction the lateral displacement reverses in the direction of the axis. Thus, a wear of the rollers is reduced and therefore increases the life of the device.
- the bearing means of a lath could comprise only one roller, which is connected to the batten and which is arranged between two steering discs, wherein a clearance between the roller and the steering discs is provided. In this case, however, the roller is braked when the direction of lateral displacement reverses in the direction of the axis, and thus a higher wear of the roller occurs.
- the in Fig. 4 and Fig. 5 shown actuator 4 is a linear actuator with a linear adjustment and is arranged such that the adjustment of the actuator 4 takes place in a direction substantially parallel to the direction of the axis A.
- the actuator can be operated electrically, hydraulically or pneumatically.
- the actuator 4 is disposed within a housing of the device or the fixed part of the device, so that it is not directly accessible from the outside and thus protected.
- the adjusting means 8 is adapted to move the pivot point D of the connecting means 5 (or the pivoting lever) in a direction perpendicular to the axis A.
- the displacement of the pivot point D is thereby achieved in that the adjusting means 8 comprises at least one recess in the connecting means 5, by means of which, as in Fig. 4 and Fig. 5 represented, different pivot points D are defined.
- the adjusting means 8 further comprises a fastening means 9, for example in the form of a bolt or a screw with locking ring.
- the connecting means 5 is pivotally connected by means of the fastening means 9 through the recess or recesses with the fixed part 10 of the device. As in Fig.
- the adjusting means 8 also includes recesses in the fixed part 10 of the device.
- the connecting means 5 is here pivotally connected to the fixed part 10 of the device by the fastening means 9 is arranged through one of the recesses in the fixed part 10 and a corresponding recess in the connecting means 5.
- the pivot point D of the connecting means 5 can be displaced by a detachable bolt connection so as to variably set the displacement ratio.
- the bolt connection allows the pivoting of the connecting means 5 about the pivot point D relative to a fixed part 10 of the device.
- adjusting means 8 comprises three recesses in the connecting means 5 and three corresponding recesses in the fixed part 10 of the device, by which three different pivot points D are defined, so that the adjustment ratio can be adjusted discretely.
- a pivot point D is defined by a respective recess.
- the adjusting means 8 may comprise only a single recess in the form of a slot through which different pivot points D are defined. This allows the ratio to be continuously adjustable.
- the detachable bolt connection can be manually arranged in another recess and thus displaced.
- the displacement ratio is constant while the roller 1 rotates or during operation of the device.
- the adjustment ratio is variably adjustable while the roller rotates or during operation of the device, for example by a drive or automatically by a controller.
- the adjustment ratio is usually smaller than 1, usually in a range of 1: 1-1: 5, about 1: 1 or 1: 2. Only as an example, with a ratio of 1: 2 and an adjustment of the actuator of 0.5 mm, the adjustment of the slat shifter (or the rollers and thus also the slats) 1.0 mm. For example, the ratio can be adjusted from 1: 1 to 1: 2 or vice versa.
- the device comprises at least one protection means 30 for a slat 2, which is arranged between the first slat region 31 and the second slat region 32 in the interior of the slat 2.
- the protection means 30 bridges a gap 33 between the first slat portion 31 and the second slat portion 32 in the direction of the axis A.
- the thickness of the bar is low, for example in the range of 0.5 to 3 mm, in particular about 1.5 mm, then an accidental intervention of the operator only leads to minor injuries, such as slight bruising of the finger.
- the protection means 30 in this case prevents serious injury, such as loss of all or a significant portion of the finger.
- the gap 33 between the first slat portion 31 and the second slat portion 32 may be substantially S-shaped, as in FIG Fig. 6 and Fig. 7 shown.
- the first slat portion 31 and the second slat portion 32 each include a protrusion 31 a, 32 a extending in the direction of a longitudinal axis of the slat 2.
- the protrusion 31 a of the first slat portion 31 and the protrusion 32 a of the second slat portion 32 are arranged to each other such that the substantially S-shaped gap 33 is formed between the first slat portion 31 and the second slat portion 32.
- the protrusion 31 a of the first slat portion 31 and the protrusion 32 a of the second slat portion 32 each extend only over a part of the width of the slat 2 and are arranged on opposite sides with respect to the longitudinal axis of the slat 2. Since the gap 33 is substantially S-shaped, optimum guidance of the split slats 2 on the roll 1 and optimum guidance of the slat regions relative to one another can be achieved.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Regeln des seitlichen Versetzens mindestens einer Materialbahn umfassend eine um eine Achse drehbar gelagerte Walze.The present invention relates to a device for regulating the lateral displacement of at least one material web comprising a roller rotatably mounted about an axis.
In bestimmten Anwendungen, insbesondere in der Textilindustrie zur Herstellung oder Bearbeitung von Textilbahnen, umfasst die Walze Latten, welche sich in Richtung der Achse erstrecken und in Umfangsrichtung der Walze angeordnet sind. Die Latten können in diesem Fall in Richtung der Achse verschoben werden, so dass eine Verschiebung der Latten in einem seitlichen Versetzen der Materialbahn resultiert, beispielsweise zur Bahnführung oder Bahnausstreifung. Eine solche Vorrichtung ist beispielsweise in
Eine Vorrichtung zum Regeln des seitlichen Versetzens mindestens einer Materialbahn umfasst mindestens eine um eine Achse drehbar gelagerte Walze, welche Latten umfasst, welche sich in Richtung der Achse erstrecken und in Umfangsrichtung der Walze angeordnet sind, wobei jede Latte in Richtung der Achse verschiebbar gelagert ist. Die Walze umfasst weiterhin mindestens ein Lattenfiihrungsmittel, auf welchem die verschiebbaren Latten geführt werden, wobei das Lattenfiihrungsmittel für jede der Latten einen entsprechenden Lattenfiihrungsbereich umfasst.A device for controlling the lateral displacement of at least one material web comprises at least one roller rotatably mounted about an axis, which comprises slats which extend in the direction of the axis and are arranged in the circumferential direction of the roller, each slat being displaceably mounted in the direction of the axis. The roller further comprises at least one slat guide on which the slidable slats are guided, the slat guide comprising a respective slat guide section for each of the slats.
Erfindungsgemäß umfasst die Walze mindestens ein Lattensicherungsmittel, welches geeignet ist, die Latten gegen ein Ablösen der Latten von der Vorrichtung bei Defekt der entsprechenden Lattenfiihrungsbereiche zu sichern, wobei das Lattensicherungsmittel für jede der Latten einen entsprechenden Lattensicherungsbereich umfasst. Es wird somit eine höhere Sicherheit der Vorrichtung bei Betrieb gewährleistet. Insbesondere können Maschinenbeschädigungen und Verletzungen des Bedienpersonals durch sich von der mit hoher Geschwindigkeit drehenden Walze ablösende Latten vermieden werden.According to the invention, the roller comprises at least one slat securing means which is suitable for securing the slats against detachment of the slats from the device in the event of the defect of the corresponding slat guide sections Slate securing means for each of the slats comprises a corresponding slack securing area. It is thus ensured a higher safety of the device during operation. In particular, machine damage and operator injury can be avoided by slats detaching from the high-speed rotating roller.
Der entsprechende Lattensicherungsbereich für eine Latte kann innerhalb der Latte angeordnet sein. Der Lattensicherungsbereich für eine Latte kann einen Kopfbereich umfassen, welcher geeignet ist, die Latte gegen ein Ablösen von der Vorrichtung bei Defekt des entsprechenden Lattenfiihrungsbereiches zu sichern. Dies ermöglicht, dass der Kopfbereich des Lattensicherungsmittels die Latte auffängt, wenn die Latte sich von der Vorrichtung ablöst und in Folge der Fliehkräfte radial weggeschleudert wird. Der Defekt des Lattenfiihrungsbereiches kann insbesondere ein Verschleiß oder ein Abbrechen des Lattenfiihrungsbereiches von dem Lattenfiihrungsmittel sein.The corresponding slat securing area for a slat may be disposed within the slat. The slat securing portion for a slat may include a head portion adapted to secure the slat against detachment from the device upon failure of the corresponding slat guide portion. This allows the head portion of the slat securing means to catch the slat when the slat detaches from the device and is thrown radially as a result of the centrifugal forces. In particular, the defect of the slat guide section may be wear or breakage of the slat guide section from the slat guide means.
Der Lattenfiihrungsbereich für eine Latte kann mindestens eine Aussparung umfassen, welche geeignet ist, die Latte gleitend aufzunehmen, um die Latte auf dem Lattenfiihrungsmittel zu führen. Hierbei kann ein Spiel zwischen Latte und Lattenfiihrungsbereich vorgesehen sein, damit die Latte gleitend aufgenommen werden kann. Die Latte und der Lattenfiihrungsbereich können derart angeordnet sein, dass ein Ablösen der Latte von der Vorrichtung bei normalem Betrieb verhindert wird. Der Lattensicherungsbereich kann ebenfalls eine Aussparung umfassen, welche größer ist als die Aussparung des Lattenfiihrungsbereiches. Dies ermöglicht, dass das Lattensicherungsmittel die Latte auffängt, wenn die Latte sich von der Vorrichtung löst. Es wird auch verhindert, dass die Latte und das Lattensicherungsmittel in Kontakt kommen bei normalen Betrieb der Vorrichtung, das heißt, wenn kein Defekt des Lattenfiihrungsbereiches vorliegt.The slat guide portion for a slat may include at least one recess adapted to slidably receive the slat for guiding the slat on the slat guide. Here, a game between lath and Lattenfiihrungsbereich be provided so that the bar can be slidably received. The batten and the slat guide section may be arranged to prevent the slat from detaching from the device during normal operation. The slat securing portion may also include a recess which is larger than the recess of the slat guide portion. This allows the slat securing means to catch the slat as the slat detaches from the device. It also prevents the slat and the slat securing means from coming into contact during normal operation of the device, that is, when there is no defect in the slat guide section.
Das Lattenfiihrungsmittel kann aus einem ersten Material hergestellt sein und das Lattensicherungsmittel kann aus einem zweiten Material hergestellt sein, welches eine höheren Härte und/oder Abriebfestigkeit als das erste Material aufweist. Das erste Material (Lattenfiihrungsmittel) kann Kunststoff sein, beispielsweise Polyethylen (z.B. PE 1000) oder Polyvinylidenfluorid (PVDF). Das erste Material kann auch ein anderes Material sein, das geeignet ist, die verschiebbaren Latten zu führen. Das zweite Material (Lattensicherungsmittel) kann Metall sein, insbesondere Stahl. Das zweite Material kann auch ein anderes Material sein, das geeignet ist, die Latten gegen ein Ablösen der Latten von der Vorrichtung bei Defekt der entsprechenden Lattenfiihrungsbereiche zu sichern. Wenn das Lattenfiihrungsmittel aus Kunststoff ist, bietet es eine gute gleitende Aufnahme der Latten, das heißt, eine Latte - beispielsweise aus Metall - kann gut auf dem entsprechenden Lattenfiihrungsbereich gleiten und somit geführt werden. Kunststoff weist jedoch einen höheren Verschleiß als beispielsweise Metall auf. Verschleiß kann beispielsweise durch überhöhte Materialbahnspannung und ein entsprechendes Verbiegen der Geometrie bzw. des Querschnitts der Latten auftreten. Somit besteht ein erhöhtes Risiko, dass die Aussparung, welche die Latte gleitend aufnimmt, durch Verschleiß soweit vergrößert wird, dass sich die Latte von der Vorrichtung lösen kann, oder es besteht Gefahr dass es sogar zu einem Abbrechen des gesamten oder zumindest eines ausreichenden Teils des Lattenfiihrungsbereiches für die Latte kommt, so dass sich die Latte von der Vorrichtung lösen kann.The slat guide may be made of a first material, and the slat securing means may be made of a second material having a higher hardness and / or abrasion resistance than the first material. The first material (Lattenfiihrungsmittel) may be plastic, for example Polyethylene (eg PE 1000) or polyvinylidene fluoride (PVDF). The first material may also be another material suitable for guiding the slidable slats. The second material (slate securing agent) may be metal, in particular steel. The second material may also be another material suitable for securing the slats against detachment of the slats from the device upon failure of the respective slat guide sections. When the slat guide is made of plastic, it provides a good sliding fit of the slats, that is, a slat - for example made of metal - can slide well on the corresponding slat guide area and thus be guided. However, plastic has a higher wear than, for example, metal. Wear can occur for example due to excessive web tension and a corresponding bending of the geometry or the cross section of the slats. Thus, there is an increased risk that the recess slidably receiving the slat will be increased by wear to the extent that the slat may become detached from the device, or there is a risk that it may even break off all or at least a sufficient portion of the slat Lattenfiihrungsbereiches for the bar comes, so that the bar can be detached from the device.
Die Latte kann im Querschnitt polygonförmig sein. Insbesondere kann die Latte im Querschnitt folgende Bereiche umfassen:
- einen mittleren Auflagebereich zum Aufliegen der mindestens einen Materialbahn,
- einen Seitenbereich an jeder Seite des mittleren Auflagebereiches, bezüglich einer in radialer Richtung verlaufenden Senkrechten, und
- einen Haltebereich angrenzend an jeden der Seitenbereiche, wobei der Haltebereich im Wesentlichen im rechten Winkel (wie z.B. 90° ± 10°) zu der Senkrechten verläuft.
- a middle support area for resting the at least one material web,
- a side region on each side of the central support region, with respect to a vertical extending in the radial direction, and
- a holding area adjacent to each of the side areas, wherein the holding area is at substantially right angles (such as 90 ° ± 10 °) to the vertical.
Die Senkrechte kann insbesondere durch den Mittelpunkt der Walze (bzw. die Achse) und den Mittelpunkt des mittleren Auflagebereiches der Latte verlaufen. Die Latte kann im Querschnitt symmetrisch sein.The perpendicular may in particular run through the center of the roller (or the axis) and the center of the central support area of the bar. The crossbar may be symmetrical in cross section.
Der Lattenfiihrungsbereich kann eine Aussparung an jeder Seite bezüglich der Senkrechten umfassen. Die Aussparungen können im Wesentlichen im rechten Winkel (wie z.B. 90° ± 10°) zu der Senkrechten verlaufen. Die Aussparungen können geeignet sein, die Haltebereiche der Latte - welche ebenfalls im Wesentlichen im rechten Winkel zu der Senkrechten verlaufen - gleitend aufzunehmen, um die Latte auf dem Lattenführungsmittel zu führen. Die Haltebereiche und die Aussparungen sind dann derart angeordnet, dass ein Ablösen der Latte von der Vorrichtung in radiale Richtung bei normalen Betrieb verhindert wird.The slat guide portion may include a recess on each side with respect to the vertical. The recesses can be essentially in the right Angle (such as 90 ° ± 10 °) to the vertical run. The recesses may be adapted to slidably receive the support portions of the slat, which are also substantially perpendicular to the normal, to guide the slat on the slat guide means. The holding portions and the recesses are then arranged such that detachment of the bar from the device in the radial direction during normal operation is prevented.
Die Walze kann einen Walzengrundkörper, beispielsweise ein Rohr, umfassen, auf welchem die Latten geführt werden können. Die Walze bzw. der Walzengrundkörper kann durch Walzenlagermittel drehbar um die Achse gelagert sein. Die Walzenlagermittel können außerhalb des von den Latten umschlossenen Bereiches der Walze (außerhalb des Innenraumes der Walze) und/oder außerhalb des feststehenden Teils der Vorrichtung angeordnet sein, so dass eine leichtere Wartung bzw. ein leichter Austausch der Walzenlagermittel ohne Demontage der Vorrichtung ermöglicht wird.The roller may comprise a roller body, for example a tube, on which the slats can be guided. The roller or the roller base body can be supported by roller bearing means rotatably mounted about the axis. The roll bearing means may be located outside of the area of the roll enclosed by the slats (outside the interior of the roll) and / or outside of the fixed part of the apparatus so as to allow easier maintenance or replacement of the roll support means without dismantling the apparatus.
Das Lattensicherungsmittel kann an dem Lattenführungsmittel befestigt sein. Alternativ kann das Lattensicherungsmittel auch an dem Walzengrundkörper befestigt sein. Das Lattenfiihrungsmittel kann mit dem um die Achse drehbar gelagerten Walzengrundkörper fest verbunden sein, beispielsweise durch eine Schraub- oder Stiftverbindung. Wenn das Lattenführungsmittel in einem rechten Winkel zu der Achse angeordnet ist, kann das Lattensicherungsmittel ebenfalls in einem rechten Winkel zur Achse angeordnet sein. Das Lattensicherungsmittel kann ringförmig sein. Das Lattenfiihrungsmittel kann ringförmig sein. Das Lattenfiihrungsmittel und/oder das Lattensicherungsmittel können geschlossen ringförmig sein oder mindestens einen Schlitz in der Ringform aufweisen. Wenn sowohl das Lattensicherungsmittel als auch das Lattenfiihrungsmittel ringförmig sind, kann das Lattenfiihrungsmittel auf den Walzengrundkörper aufgeschoben werden und mit diesem befestigt werden und das Lattensicherungsmittel kann auf den Walzengrundkörper aufgeschoben werden und an dem Lattenfiihrungsmittel befestigt werden, oder auch direkt auf dem Walzengrundkörper befestigt werden. Dies ermöglicht, dass das Lattensicherungsmittel auf einfache Weise in der Vorrichtung angebracht werden kann.The slat securing means may be attached to the slat guiding means. Alternatively, the lath securing means may also be attached to the roller body. The Lattenfiihrungsmittel can be firmly connected to the rotatably mounted about the axis roller body, for example by a screw or pin connection. When the slat guide means is disposed at a right angle to the axis, the slat securing means may also be arranged at a right angle to the axis. The lattice securing agent may be annular. The slat guide may be annular. The slat guide means and / or the slat securing means may be closed annular or have at least one slit in the annular form. If both the slat securing means and the slat guide are annular, the slat guide can be slid onto and secured to the roll body and the slat securing means can be slid onto the roll body and attached to the slat guide, or even secured directly to the roll body. This allows the slat securing means to be easily mounted in the device.
Die Latten können durchgehend sein. Alternativ können die Latten geteilt sein, wobei jede Latte einen ersten Lattenbereich und einen zweiten Lattenbereich in Richtung der Achse umfasst, wobei der erste Lattenbereich und der zweite Lattenbereich gegeneinander verschiebbar sind (geteilte Latten). Durch die Teilung wird eine Lücke zwischen dem ersten Lattenbereich und dem zweiten Lattenbereich gebildet. Das Lattenfiihrungsmittel kann in einem geringen Abstand zu der Lücke angeordnet sein. Dies ermöglicht, dass die geteilten Latten optimal abgestützt werden.The slats can be continuous. Alternatively, the slats may be split, each slat comprising a first slat area and a second slat area in the direction of the axis, wherein the first slat area and the second slat area are slidable relative to each other (split slats). The division forms a gap between the first slat region and the second slat region. The slat guide may be located a short distance from the gap. This allows the split battens to be optimally supported.
Im Falle geteilter Latten kann die Walze mindestens ein Schutzmittel für eine Latte umfassen, welches zwischen dem ersten Lattenbereich und dem zweiten Lattenbereich im Inneren der Latte angeordnet ist, und geeignet ist, eine Lücke zwischen dem ersten Lattenbereich und dem zweiten Lattenbereich in Richtung der Achse zu überbrücken. Es wird somit eine höhere Sicherheit der Vorrichtung bei Betrieb gewährleistet. Insbesondere können Verletzungen des Bedienpersonals durch versehentliches Eingreifen des Bedienpersonals, beispielsweise mit dem Finger, in die Lücke zwischen dem ersten und dem zweiten Lattenbereich vermieden bzw. reduziert werden und es können auch keine anderen Gegenstände, wie Einführhilfen (z.B. Gurte oder Seile), in die Lücke gelangen.In the case of split battens, the roller may comprise at least one protection means for a batten disposed between the first batten region and the second batten region inside the batten, and is adapted to provide a gap between the first batten region and the second batten region in the direction of the axis bridged. It is thus ensured a higher safety of the device during operation. In particular, injuries to the operator can be avoided or reduced by accidental intervention of the operator, for example, with the finger, in the gap between the first and the second lath area and it can also no other items, such as insertion aids (eg straps or ropes) in the Gap.
Die Vorrichtung kann mindestens ein Lattenverschiebungsmittel zum Verschieben der Latten in Richtung der Achse umfassen, und mindestens einen Stellantrieb. Der Stellantrieb kann mit dem Lattenverschiebungsmittel durch mindestens ein Verbindungsmittel derart verbunden sein, dass eine Verstellung des Stellantriebes in einer Verstellung des Lattenverschiebungsmittels resultiert, um die mindestens eine auf den Latten aufliegende Materialbahn beim Betrieb seitlich in Richtung der Achse zu versetzen. Das Verbindungsmittel kann derart angepasst sein, dass die Verstellung des Stellantriebes und die Verstellung des Lattenverschiebungsmittels in einem bestimmten Verhältnis zueinander stehen. Das Verhältnis kann variabel einstellbar sein. Durch die variable Einstellung des Verhältnisses wird eine individuelle Anpassung an die jeweilige Anwendung der Vorrichtung ermöglicht. Es können somit verschiedene Stärken bzw. Verstärkungen des seitlichen Versetzens erreicht werden bei ansonsten gleicher Ansteuerung des Stellantriebes. Insbesondere kann die Stärke des seitlichen Versetzens somit in einfacher Weise an die Art der Materialbahn, beispielsweise Textilbahn oder Gummibahn, angepasst werden.The apparatus may comprise at least one slat shifting means for displacing the slats in the direction of the axis, and at least one actuator. The actuator may be connected to the slat displacement means by at least one connecting means such that an adjustment of the actuator results in an adjustment of the slat displacement means to offset the at least one resting on the slats web during operation in the direction of the axis. The connecting means may be adapted such that the adjustment of the actuator and the adjustment of the slat-displacing means are in a certain relationship to one another. The ratio can be variably adjustable. The variable setting of the ratio allows individual adaptation to the particular application of the device. It can thus different strengths or gains of the lateral displacement can be achieved with otherwise the same Actuation of the actuator. In particular, the strength of the lateral displacement can thus be adapted in a simple manner to the type of material web, for example textile web or rubber web.
Die Materialbahn kann beispielsweise eine Textilbahn, eine Papierbahn, eine Kunststoffbahn oder eine Gummibahn, insbesondere zur Herstellung von Reifen, sein.The material web can be, for example, a textile web, a paper web, a plastic web or a rubber web, in particular for the production of tires.
Die Vorrichtung kann kontinuierlich betrieben werden. Dies hat den Vorteil, dass der Produktionsprozess beschleunigt wird und somit Kosten gespart werden. Alternativ kann die Vorrichtung diskontinuierlich betrieben werden, beispielsweise mit Stoppintervallen zum Schneiden der Materialbahn.The device can be operated continuously. This has the advantage that the production process is accelerated and thus costs are saved. Alternatively, the device can be operated discontinuously, for example with stop intervals for cutting the material web.
Die vorliegende Erfindung betrifft außerdem eine Anlage zur Reifenherstellung oder Reifenbearbeitung, welche eine der oben beschriebenen Vorrichtungen zum Regeln des seitlichen Versetzens mindestens einer Materialbahn umfasst.The present invention also relates to a tire-building or tire-working equipment which comprises one of the above-described devices for regulating the lateral displacement of at least one material web.

Fig. 1 zeigt eine perspektivische Ansicht der Vorrichtung zum Regeln des seitlichen Versetzens mindestens einer Materialbahn. Die Vorrichtung umfasst eine um eine Achse A drehbar gelagerte Walze 1. Die Walze 1 umfasst Latten 2, welche sich in Richtung der Achse A erstrecken und in Umfangsrichtung der Walze 1 angeordnet sind. Die Latten 2 sind in Richtung der Achse A verschiebbar gelagert. In der inFig. 1 dargestellten Konstruktion sind sieben Latten in Umfangsrichtung der Walze 1 vorgesehen. Allgemein hängt die Anzahl der Latten vom Durchmesser der Walze und von der Breite der Latten ab. Es sollte zudem ein Sicherheitsabstand zwischen den Latten 2 eingehalten werden, damit die Latten 2 sich gegenseitig nicht berühren. Dieser Sicherheitsabstand sollte jedoch gering genug sein, so dass die Materialbahn gut auf der Walze aufliegen kann und so dass keine Verletzungen des Bedienpersonals durch Eingreifen in den Raum zwischen den in Umfangsrichtung der Walze angeordneten Latten auftreten können. Die Latten können beispielsweise aus Metall hergestellt sein, insbesondere Edelstahl. Die Latten können eine Beschichtung aufweisen, welche an die jeweilige Anwendung angepasst ist.Fig. 1 shows a perspective view of the device for controlling the lateral displacement of at least one material web. The device comprises aroller 1 rotatably mounted about an axis A. Theroller 1 comprisesslats 2 which extend in the direction of the axis A and are arranged in the circumferential direction of theroller 1. Theslats 2 are slidably mounted in the direction of the axis A. In the inFig. 1 shown construction seven slats in the circumferential direction of theroller 1 are provided. Generally, the number of slats depends on the diameter of the roll and the width of the slats. In addition, a safety distance should be maintained between theslats 2, so that theslats 2 do not touch each other. However, this safety distance should be low enough so that the material web can rest well on the roller and so that no injuries to the operator by intervention in the space between the arranged in the circumferential direction of the roller slats can occur. The slats can be made, for example, of metal, in particular stainless steel. The slats may have a coating which is adapted to the particular application. -

Alternativ könnte das Lagermittel einer Latte nur eine Rolle umfassen, welche mit der Latte verbunden ist und welche zwischen zwei Lenkscheiben angeordnet ist, wobei ein Spiel zwischen der Rolle und den Lenkscheiben vorgesehen ist. In diesem Fall wird die Rolle jedoch abgebremst, wenn sich die Richtung des seitlichen Versetzens in Richtung der Achse umkehrt, und somit tritt ein höherer Verschleiß der Rolle auf.Alternatively, the bearing means of a lath could comprise only one roller, which is connected to the batten and which is arranged between two steering discs, wherein a clearance between the roller and the steering discs is provided. In this case, however, the roller is braked when the direction of lateral displacement reverses in the direction of the axis, and thus a higher wear of the roller occurs.

side portion 30b on each side of thecentral portion 30a with respect to a vertical S.
Die Senkrechte S verläuft durch den Mittelpunkt des mittleren Bereiches 30a des Schutzmittels.

Die Vorrichtung kann auch kontinuierlich betrieben werden, das heißt die Regelung des seitlichen Versetzens wird vorgenommen während die Walze sich dreht. Dies ist beispielsweise der Fall, wenn die Vorrichtung im Bereich des Umrollers, des Extruders, und/oder des Kalanders in der Anlage zur Reifenherstellung verwendet wird. Alternativ kann die Vorrichtung aber auch diskontinuierlich betrieben werden, das heißt, die Regelung des seitlichen Versetzens wird in Stoppintervallen vorgenommen, in denen die Walze sich nicht dreht. Dies ist beispielsweise der Fall, wenn die Vorrichtung im Bereich der Schneidevorrichtung in der Anlage zur Reifenherstellung verwendet wird, wobei während der Stoppintervalle die Materialbahn durch die Schneidevorrichtung geschnitten wird.The device can also be operated continuously, that is, the lateral displacement control is performed while the roller is rotating. This is the case, for example, when the device is used in the area of the rewinder, the extruder, and / or the calender in the tire manufacturing plant. Alternatively, however, the device may also be operated discontinuously, that is, the lateral displacement control is performed at stop intervals in which the roller does not rotate. This is the case, for example, when the device is used in the region of the cutting device in the tire manufacturing plant, wherein during the stop intervals the material web is cut by the cutting device.
Die Vorrichtung kann auch in anderen Anwendungen verwendet werden, wie in einer Anlage zur Textilherstellung oder Textilbearbeitung, wobei die Materialbahn dann eine Textilbahn ist. Die Vorrichtung kann auch in einer Anlage zur Papierherstellung oder Papierbearbeitung, wobei die Materialbahn dann eine Papierbahn ist, oder in einer Anlage zur Kunstofffolienherstellung oder Kunstofffolienbearbeitung, wobei die Materialbahn dann eine Kunstoffbahn ist, verwendet werden.The device can also be used in other applications, such as in a textile manufacturing or textile processing plant, the web then being a textile web. The apparatus may also be used in a papermaking or papermaking plant, the web then being a paper web, or in a plant for plastic film production or plastic film processing, the web then being a plastic web.
Die Vorrichtung kann ein Detektionsmittel (nicht gezeigt) zur Detektion der Position der Materialbahn umfassen. Auch kann die Vorrichtung eine Steuereinrichtung (nicht gezeigt) zum Regeln des seitlichen Versetzens umfassen. Die Steuereinrichtung ist dann mit dem Detektionsmittel und dem Stellantrieb derart verbunden, dass die Steuereinrichtung Signale des Detektionsmittels auswertet und den Stellantrieb entsprechend ansteuert, um das seitliche Versetzen der Materialbahn zu regeln. Das Detektionsmittel kann ein Bahnkantensensor sein, der die Kante der Materialbahn mittels einer Lichtschranke detektiert, und/oder eine Kamera. Es können jedoch auch andere Arten von Detektionsmitteln vorgesehen sein.The device may include a detection means (not shown) for detecting the position of the web of material. Also, the apparatus may include control means (not shown) for controlling lateral displacement. The control device is then connected to the detection means and the actuator such that the control device evaluates signals of the detection means and controls the actuator accordingly to regulate the lateral displacement of the material web. The detection means may be a web edge sensor which detects the edge of the material web by means of a light barrier, and / or a camera. However, other types of detection means may be provided.
