[0001] The present invention relates to a winding device for winding up and winding up ropes. Background Technology
[0002] When winding a rope onto a seiltrommel, the individual rope loops should be placed directly and firmly side-by-side to produce a good winding pattern. To achieve this, the rope must be offset from the axial direction of the seiltrommel by approximately the rope's diameter for each revolution of the seiltrommel. This offset of the rope in the axial direction of the seiltrommel is also known as the rope pitch.
[0003] It is known that a good winding profile is produced when the overwind angle (Auflaufwinkel) of the rope, measured relative to a plane perpendicular to the axis of rotation of the rope drum, is not significantly greater than 3º. The overwind angle is measured on the tangential plane of the rope already wound on the rope drum, at the point where the rope begins to wind onto the already wound rope layer (or seillage). The tangential plane is positioned at a distance from the axis of rotation equal to the average radius of the outermost wound rope layer. This so-called "+ / -3º-winding principle" uses a rope winding method in which the overwinding rope is guided to the rope drum by fixed rope rods (Seilpol). The rope rods are spaced so far apart in a direction perpendicular to the axis of rotation of the rope drum that the overwind angle at the edge discs (Bordscheibe) of the rope drum is at most 3º. The rope rods are typically centered between the edge discs of the rope drum. To ensure the top winding angle does not significantly exceed 3º, the distance between the rope rods and the axis of rotation of the rope drum must be at least 9.5 times the distance measured along the axis of rotation of the rope drum's edge discs. This arrangement ensures that the loops of rope being wound are placed side-by-side without further guidance. When the rope collides with the edge disc, the axial winding direction automatically reverses. To prevent the rope at the edge disc from overlapping in multiple loops and instead extending in another axial winding direction, the so-called winding angle must not be too small. The winding angle is equal to the top winding angle of the rope on the rope drum when the rope reaches the edge disc. At a winding angle of 3º, the rope wound at the edge disc is pulled away from the edge disc again. This arrangement produces a good winding pattern. However, a disadvantage is the large installation space required for this winding device.
[0004] It is also known to use a winding arm or pivoting arm to wind up the rope. The winding arm is mounted so as to pivot freely about a pivot axis. The pivot axis is typically arranged in the middle of the rope drum in a plane perpendicular to the axis of rotation of the rope drum. In the case of the "+ / -3º winding principle", the pivot axis can be arranged much closer to the rope drum than the rope rod, which is why this winding device requires less installation space. The wound rope is guided to the rope drum along the winding arm. The winding arm has a deflector roller at its end facing the rope drum. The rope is wound onto the rope drum from the deflector roller at a small angle. For this purpose, the rope is typically deflected about 90º at the deflector roller. Thus, the rope extends approximately parallel to the pivot axis of the winding arm in the winding area on the rope drum. In this winding device, the winding angle of the rope on the rope drum is determined not only by the pivoting position of the pivoting arm but also by the position of the deflector element relative to the rope drum. The position of the deflecting elements is determined by the radial distance between the deflecting elements and the axis of rotation of the rope drum, and the axial distance between the deflecting elements and the center plane of the rope drum, which is measured in the direction of the axis of rotation of the rope drum. The center plane is oriented perpendicular to the axis of rotation of the rope drum and is positioned midway between the two edge discs of the rope drum. The upwind angle is measured relative to a plane perpendicular to the axis of rotation of the rope, at the upwind point of the rope toward the already wound rope layer, in the tangential plane of the rope already wound onto the rope drum. The tangential plane is positioned at a distance from the axis of rotation equal to the average radius of the outermost wound rope layer.
[0005] Typically, winding devices with a winding arm are arranged such that when the rope deflects 90° on the deflector roller, the upwind angle of the rope is approximately 0°. This is usually the case when the winding arm is in the middle between the two edge discs, when the rope is half-wound. Due to the pivoting motion of the winding arm about the pivot axis, the deflector roller moves on a circular track relative to the pivot axis. When the winding arm deviates from the middle position (where the rope deflects approximately 90° at the deflector element), the deflection angle of the rope at the deflector element changes. This arrangement is typically designed such that the deflection angle becomes smaller as the winding arm pivots away from the middle position. As the winding arm pivots out of the middle position, the upwind angle of the rope on the rope drum becomes larger. Due to the positioning of the deflector roller at the free longitudinal end of the winding arm relative to the rope drum, and due to the deflection of the rope on the deflector roller, the upwind angle can also be maintained below 3° in this arrangement, although in winding devices with fixed rope rods, the distance between the pivot axis and the axis of rotation of the rope drum is smaller than the spacing of the rope rods. In this arrangement, the winding angle can be greater than or equal to 3º. The winding angle is the angle at which the rope is wound up when it hits the edge disc. Ideally, the winding angle is 3º. Winding devices with winding arms have a free-moving rope rod, i.e., a deflecting element.
[0006] This type of winding arm can only be used to wind ropes onto a storage drum. Most of the force caused by the load suspended on the rope or the tension acting on the rope is absorbed here by a winch positioned between the load and the storage drum. In the case of the storage drum, a constant preload, large or small, is always applied, which is much smaller than the winch's tension. In contrast, the rope drum, constructed as part of the winch, bears the maximum tension, as this maximum tension is a major component of the winch itself. The force on the rope fluctuates between no force and the winch's maximum tension. The winding device with the winding arm still has an excessively small compactness, although this is an improvement over the + / -3º winding principle using a fixed rod.
[0007] Other winding devices exist, such as systems that can move parallel and reciprocate, driven by a rope drum via a cross screw, or equipped with external actuators and controllers. They all have the same function of orderly unwinding the rope onto the rope drum, i.e., one loop following another, thus ensuring a secure and gapless rope belt, and during layer changes, the rope is turned away from the edge disc in a prescribed opposite direction. Summary of the Invention
[0008] The purpose of this invention is to provide a winding device that provides a good winding pattern in the case of limited installation space.
[0009] This objective is achieved by a winding device for winding a rope onto a rope drum rotatable about a rotation axis. The winding device includes a rope guide for supplying the rope to the rope drum, wherein the rope guide has a pivot arm with a longitudinal axis and a deflection element, wherein the pivot arm is pivotable about the pivot axis, wherein the deflection element is arranged at the pivot arm, wherein the winding device is designed such that the rope passes in front of the deflection element on the pivot arm as it is wound onto the rope drum, wherein the rope guide includes a limiting element, and wherein the limiting element is arranged such that the pivoting movement of the pivot arm about the pivot axis is limited to a critical angle range, and the deflection element is tiltable about an inclined axis extending along the longitudinal axis of the pivot arm.
[0010] Based on known winding arms, the desired compactness and durability can be achieved cost-effectively through modifications. Therefore, the present invention is based on a winding device with a winding arm.
[0011] This invention is based on the understanding that in compact winding devices with shorter pivot arms due to desired compactness, it is difficult or almost impossible to maintain an upwind angle of the rope on the rope drum ≤3º across the entire width of the rope drum. Due to the required compactness, the pivot angle of the pivot arm must be very large to guide the deflection element sufficiently close to the edge disc. Only in this way can the reverse movement of the rope on the rope drum be correctly achieved during layer changes.
[0012] To provide a rope guide capable of achieving an upwind and winding angle of ≤3º, independent of the length of the pivot arm or the pivotable portion of the rope guide relative to the reference pivot axis, the deflecting element is obliquely supported about an inclined axis extending along the longitudinal axis of the pivot arm. Specifically, the inclined axis extends centrally relative to the rope. Due to the oblique nature of the deflecting element, an upwind angle of less than 3º on the rope drum can be achieved over a wide angle range, even with a short pivot arm. It is thus feasible to achieve a winding angle of approximately 3º even with a short pivot arm. It is particularly feasible to achieve winding angles of 2º to 4º, suitably 2.5º to 3.5º, especially 2.8º to 3.2º, and preferably 2.9º to 3.1º, even with a short pivot arm. Due to the oblique design of the deflecting element, the winding device can be compactly designed while still providing a good winding pattern when the rope is wound onto the rope drum. The winding device according to the invention requires only a small installation space while still providing a good winding pattern. The tiltable deflector element limits the pivot angle of the winding arm. Because of the tiltable deflector element, the rope output opening extending from the deflector element can be close to the edge disc even when the pivot arm is fixed. This allows for a small upward winding angle.
[0013] The rope guide is configured to include a limiting element, which is configured to restrict the pivoting movement of the pivot arm about the pivot axis within a critical angle range. The critical angle range is particularly a continuous angle range. The critical angle range is suitably up to 135º, particularly up to 90º, preferably up to 70º, and especially preferably up to 60º.
[0014] The rope drum has a radius. The distance between the pivot axis and the axis of rotation of the rope drum is suitably greater than the radius of the rope drum. The distance between the pivot axis and the axis of rotation of the rope drum is particularly less than twice the radius of the rope drum, preferably less than 1.5 times.
[0015] The limiting element is a component of the winding device and is constructed independently of the rope drum. Due to the tiltability of the deflecting element, it can continue to follow the rope wound onto the rope drum even when the pivot arm is against the limiting element. The smaller pivot angle due to the limiting element and the tiltability of the deflecting element allow for a good winding pattern even with a compact winding arm design. In particular, a winding angle of approximately 3º can be achieved despite the short length of the pivotable portion of the winding arm or winding device. The rope winding angle can still be less than 3º despite the short length of the pivotable portion of the winding arm or winding device.
[0016] Winding devices are particularly suitable for winding and unwinding, and for multi-layered ropes. They are especially suitable for both traction and hoisting winches, where higher safety standards must be met. Winding devices are suitably designed for traction applications with forces ranging from 10 kN to 1000 kN, particularly 50 kN to 500 kN. Winding devices are also suitably designed for hoisting applications with forces ranging from 1 kN to 100 kN, particularly 10 kN to 50 kN.
[0017] The pivot arm suitably has a rope window. A rope can pass through the rope window. The rope is supplied to the pivot arm through the rope window during winding. Specifically, the pivot arm is designed such that the rope is guided along the pivot arm from the rope window to the deflection element.
[0018] Due to the limiting element and the associated limitation on the pivoting range of the pivot arm, the magnitude of rope deflection is limited when the rope enters through the rope window. This results in virtually no wear on the rope. The rope has a long lifespan.
[0019] In particular, the combination of tiltable deflector elements and limiting elements enables a compact structure for the winding device while maintaining a good winding pattern. The winding device can thus be designed so that even when the pivot arm is at the edge of the critical angle range, the rope can be guided by the rope guide to an area of the rope drum outside the critical angle range due to the tiltable deflector element. In this case, collisions between the pivotable portion of the winding device and one of the two edge discs or the rope strip can be avoided. The rope strip refers to the portion of the rope wound onto, and particularly multiple times wound onto, the rope drum.
[0020] In a similar manner, the rope can be wound from the rope drum using the winding device according to the invention. For this application, the compactness of the winding device according to the invention is also advantageous, achieved through the tiltability of the limiting element and the deflecting element.
[0021] The winding device is advantageously designed such that the deflector element can tilt about an inclined axis, allowing the rope to be guided by the deflector element into an angle range outside the critical angle range. Thus, the arm length of the pivot arm, measured perpendicular to the pivot axis, can be very small, while still achieving a good winding pattern. The pivotable portion of the rope guide has a pivot length measured perpendicular to the pivot axis, starting from the pivot axis. Because the rope can be guided by the tiltable deflector element into an angle range outside the critical angle range, the pivot length can be very small, while still achieving a good winding pattern.
[0022] Specifically, the deflecting element is arranged in an inclined position with reference to the tilt axis. The pivot arm is arranged in a pivot position with reference to the pivot axis. Specifically, the deflecting element can be freely tilted about the tilt axis in any pivot position of the pivot arm. In an advantageous improvement of the invention, the winding device includes an adjusting device, and the adjusting device presets the tilt position according to the pivot position. Therefore, the winding device can be designed such that the rope is continuously fed onto the rope drum in the direction of the rope drum's rotation axis, regardless of the guidance of the pre-tensioned rope. Thus, the feed in the direction of the rope drum's rotation axis is uniform and continuous, regardless of the pre-tensioning and guidance of the rope. Specifically, the rope can be wound at a preset upwind angle within a critical angle range. By means of the adjusting device, the winding device can be designed to produce a good winding pattern, regardless of the force acting on the rope (e.g., due to load). The winding device can be designed to produce a good winding pattern even with variations in load. The greater the load / force in the rope, the better the winding pattern. Ideally, the force on the rope should be 2% of the rope's minimum breaking strength.
[0023] It can be configured such that, at the edge of the critical angle range within the pivot arm's edge position, multiple different tilt positions of the deflection element are possible, provided the pivot position of the pivot arm is the same. Advantageously, the deflection element operates freely at the edge position of the critical angle range. In particular, the deflection element operates freely in each pivot position of the pivot arm.
[0024] Specifically, the deflection element is forcibly controlled within a critical angle range. It can be configured such that the deflection element is forcibly controlled at each pivot position of the pivot arm. Specifically, the winding device is designed such that the maximum tilt angle of the deflection element exists at the edge position of the pivot arm. Suitably, the winding device is designed such that a stepless transition is achieved between the minimum and maximum tilt angles during pivot arm pivoting regarding the tilt position of the deflection element.
[0025] In an advantageous improvement of the invention, the rope guide has a pivoting drive. Specifically, the winding device is designed such that the pivot arm can move back and forth within a critical angle range via the pivoting drive. Specifically, the winding device has a pivot actuator. The pivoting drive is suitably an integral part of the pivot actuator. Advantageously, the pivot actuator is reversible.
[0026] Specifically, the pivoting drive includes a crank drive. Suitably, the pivoting drive has a shaft rotatable about a centerline, a pin eccentrically arranged relative to the centerline and movable about the centerline by means of the shaft, and a connecting rod. Specifically, the connecting rod connects the pin to the pivot arm. The connecting rod is suitably rotatably supported on the pin.
[0027] The pivoting drive (especially the crank drive) is preferably designed such that the distance between the axis and the pin changes as the pin moves about its axis. This compensates for irregularities that would otherwise occur when guiding the pin on a circular track due to the arrangement of the connecting rods. Suitably, the distance between the axis and the pin changes as the pin moves about its axis, resulting in a constant feed when the rope is wound onto the rope drum. In particular, the distance changes as the pin moves about its axis, achieving a constant rope pitch when the rope is wound onto the rope drum. Rope pitch refers to the offset of the rope in the direction of the rope drum's axis of rotation. In particular, the winding device is designed such that, as the rope drum rotates about its axis of rotation, the pivot arm offsets in the direction of the rope drum's axis of rotation by 100% to 110% of the rope diameter, particularly 100% to 105% of the rope diameter, preferably 100% to 102% of the rope diameter.
[0028] Suitably, the pivoting drive has a cam disk with a track in which a pin is guided along its path around the axis. Specifically, the cam disk is fixed relative to the rotating disk of the pivoting drive. Suitably, the rotating disk can be rotated about the axis by the pivoting drive. Specifically, the rotating disk has an elongated hole that completely penetrates the rotating disk in the direction of the axis and extends radially along the axis. Specifically, a pin plug passes through the elongated hole of the rotating disk and through the track of the cam disk. Thus, the crank radius and the movement of the pivoting arm can be linearized. The movement of the longitudinal end of the pivoting arm facing the deflection element in the direction of rotation can thus be performed at a constant speed. It can also be configured such that the speed of the longitudinal end of the pivoting arm in the direction of rotation is proportional to the rotational speed of the rope drum.
[0029] In an advantageous improvement of the invention, the deflecting element comprises a plurality of rollers. Specifically, the rollers are arranged side-by-side on a curved track. This allows for compact deflection of the rope. In this case, the rope bears only a small mechanical load. Specifically, the wrap angle of the rope around each individual roller is at most 25º, suitably at most 15º, advantageously at most 10º, and preferably at most 5º. By arranging the rollers on a curved track, the diameter of each roller can be very small, and the output opening of the deflecting element for the rope can be brought closer to the outer circumference of the rope drum. The output opening of the deflecting element can be brought closer to the rope belt. Arranging the rollers on a curved track allows for better rope supply to the rope drum, producing a good winding pattern.
[0030] When using a single roller as the deflection element, the wrap angle of the single roller will be much larger than the wrap angle of any single roller among the multiple rollers of the deflection element according to the improved invention. To keep the rope stress low, the diameter of the single roller must be much larger, which prevents the rope from being guided so close to the rope drum because the unused side of the single roller protrudes towards the rope drum due to its larger diameter. Since the diameter of the single roller will be many times larger than the diameter of any single roller among the multiple rollers of the deflection element according to the improved invention, a much larger distance from the rope drum will be required for the single roller compared to the deflection element according to the improved invention. Due to the multiple rollers, the winding device can be constructed compactly.
[0031] The curved track is suitably elliptical in orientation. This elliptical orientation can be observed in the direction perpendicular to the deflection plane. This allows for the design of uniform contact force across the rollers.
[0032] In an advantageous improvement of the invention, the winding device is an integral part of the rope winding device. The rope winding device includes a rope drum and a winding mechanism. In particular, the rope drum has two edge discs. The rope winding device is suitably designed such that the pivot arm can pivot back and forth between the two edge discs about a pivot axis.
[0033] Specifically, the winding device is designed such that a critical angle range limits the pivoting movement of the pivoting arm to a range within which the pivotable portion of the rope guide avoids contact between the edge discs of the rope drum or the imaginary plane of the edge discs. The edge discs are also called edge walls. By limiting to the critical angle range, collisions between the pivotable portion of the rope guide and the edge discs or rope strips can be avoided. Without limiting elements, the pivotable portion of the rope guide will pivot between the two edge discs within the maximum edge angle range between them, particularly between the planes associated with the edge discs. The pivotable portion of the winding device can collide, particularly with the edge discs or rope strips. The critical angle range is suitably up to 80% of the maximum edge angle range. Specifically, the critical angle range is up to 75% of the maximum edge angle range. Preferably, the critical angle range is up to 70% of the maximum edge angle range. In particular, the critical angle range is arranged symmetrically between the two edge discs with respect to the direction of the rope drum's axis of rotation. However, it can also be configured such that the critical angle range is asymmetrically arranged with reference to a central plane that extends perpendicularly to the axis of rotation between the two edge disks. The location of the critical angle range can be selected based on the optimal winding angle.
[0034] Each edge disc has a diameter measured perpendicular to the axis of rotation. The largest of these diameters is called the maximum diameter. Advantageously, the pivot length is at most 100% of the maximum diameter. In particular, the pivot length is at most 95% of the maximum diameter. Preferably, the pivot length is at most 90% of the maximum diameter. This allows for a compact construction of the winding device. The winding device requires only a small installation space. Due to the shorter pivot length, only a small torque acts through the rope on the pivotable portion of the rope guide. In particular, due to the shorter pivot length, the lever torque acting on the pivotable portion of the winding device is smaller. A winding device with a pivot length of at most 100% of the maximum diameter can wind up the rope, and a larger force (e.g., due to the load suspended on the rope) acts on the rope.
[0035] The rope winding device advantageously includes a drum drive for driving the rope drum. This allows the rope to be wound onto the rope drum in a simple manner. It also allows the rope to be wound onto the rope drum in a power-adjustable manner. Specifically, one end of the rope is fixed to the rope drum. Specifically, the rope is an integral part of the rope winding device. The rope drum is advantageously configured as a component for storing drums.
[0036] The rope winding device is advantageously designed such that when the rope drum is in a specific rotational position relative to the axis of rotation, the rope guide (particularly the pivot arm of the rope guide) occupies a pivotal position that depends on the rotational position. Therefore, the pivot arm can be configured for forced control.
[0037] Suitably, the rope winding device has a drum driver for driving the rope drum, particularly the drum of the rope drum. Specifically, the drum driver is part of a pivot drive, and the pivot transmission is part of the pivot drive. The drum driver and the pivot drive preferably use a common motor. Specifically, the pivot drive and the drum driver are matched to each other. The motor suitably drives the rope drum, which is designed as a component of the storage drum, and the pivot transmission connected in series. The motor drives the storage drum via a separate transmission, and the pivot transmission is attached to the storage drum.
[0038] Suitably, the winding device is driven by a rope drum configured as a component of a storage drum and a pivoting drive that is driven through it. Specifically, the transmission ratio of the pivoting drive is twice the number of rope turns in the rope layers of the rope drum. The number of rope turns in each rope layer is the same. The total transmission ratio of the pivoting drive is suitably about 20 to 50. Specifically, the transmission ratio of the pivoting drive is achieved by a chain drive and a worm gear drive. The chain drive is suitably suspended at the rope drum and drives the worm gear drive. The shaft, connected to the connecting rod of the pivot arm, is advantageously located at the worm gear drive. The shaft is a component of the crank drive.
[0039] Specifically, the pivot drive returns via two positions and, after sweeping the pivot angle in both directions (back and forth) along the axis of rotation of the rope drum, returns to its initial position. Suitably, the worm gear drive has a fixed gear ratio, and the number of turns is adjusted by a chain drive. Specifically, the chain drive covers a gear ratio of approximately 2.5.
[0040] Specifically, the rope drum is a component of the drum winch. The total tension is transmitted from the rope to the rope drum, which is part of the drum winch.
[0041] However, it can also be configured such that the rope drum is an integral part of the storage drum. Only the preload is transmitted from the rope to the rope drum, which is part of the storage drum. Attached Figure Description

Detailed Implementation
[0043] Figure 1A rope winding device is shown. This device includes a winding mechanism 40 and a rope drum 3 with a rope 2. The winding mechanism 40 is used to wind the rope 2 onto the rope drum 3. For this purpose, the rope drum 3 is rotatably supported about a rotation axis 50. The winding mechanism 40 is used to unwind the rope 2 from the rope drum 3.
[0044] The rope winding device is suitable for multi-level operation. The winding device 40 is suitable for hoisting winches and traction winches. The winding device 40 is designed for traction applications with forces ranging from 10 kN to 1000 kN (50 kN to 500 kN in these embodiments). The winding device 40 is designed for hoisting applications with forces ranging from 1 kN to 100 kN (10 kN to 50 kN in these embodiments).
[0045] The rope winding device includes a base 19. The base 19 is a component of the rope drum 3. The drum of the rope drum 3 is rotatably supported at the base 19. The base 19 is also referred to as a support bearing.
[0046] The rope reel 3 includes a reel, two edge discs 4, and a base 19. The reel has a reel cover. The reel cover extends between the two edge discs 4. The reel cover rotates about a rotation axis 50. The reel cover has the shape of a cylindrical outer circumference.
[0047] The rope winding device has a drum driver. The drum driver is used to drive the rope drum 3 to rotate about a rotation axis 50. In these embodiments, the drum driver includes a motor (not shown) having a motor rotation axis 45. The drum driver includes a transmission device (not shown). This transmission device is arranged between the motor and the rope drum 3. Alternatively, the drum driver may not have such a transmission device. In these embodiments, the motor rotation axis 45 extends coaxially with the rotation axis 50 of the rope drum 3. The motor drives the rope drum 3.
[0048] Rope 2 is fixed at one end to rope drum 3. Rope drum 3 has... Figure 1 The two edge discs 4 are shown. The edge discs 4 restrict the winding space for the rope 2 in the direction of the rotation axis 50. The winding space is restricted in the radial direction of the rotation axis 50 by the drum of the rope drum 3. Between the edge discs 4, the rope 2 can be wound onto the drum of the rope drum 3. The rope winding device is designed such that the rope 2 is wound onto the rope drum 3 such that, when winding, the loops are first placed one after another onto the rope drum 3 with reference to the direction of the rotation axis 50 until the rope 2 touches the edge discs 4. When the rope 2 touches the edge discs 4, the rope... Figure 5The rope 2 is wound onto the rope drum 3 at the indicated winding angle α. The winding angle α is measured relative to plane G in the tangential plane of the rope 2 already wound on the rope drum 3, at the point where the rope 2 is wound towards the top layer of the already wound rope 2. The tangential planes are arranged at a distance of 50 from the axis of rotation, which is equal to the average radius of the outermost layer of wound rope. Figure 5 In the diagram, the tangential plane extends parallel to the drawing plane. Each edge disc 4 is arranged in plane G. Plane G extends perpendicular to the axis of rotation 50. Plane G rests on the inner side of the edge disc 4. The inner sides of the edge discs 4 face each other. The inner sides of the edge discs 4 limit the space for receiving the rope 2 in the rope reel 3.
[0049] After rope 2 collides with edge disc 4, the axial winding direction of rope 2 changes. The rope now winds away from the edge disc 4 that rope 2 touched and winds towards the opposite edge disc 4. In this case, a new layer of rope is generated in the radial direction about the axis of rotation 50. In this way, a neat winding pattern is produced.
[0050] In these embodiments, the rope drum 3 is part of the storage drum. The storage drum includes a drum driver. The storage drum includes a controller (not shown). The storage drum includes a rope guide 5. Upstream of the rope drum 3 is a rope winch (not shown). Only preload is transmitted from the rope 2 to the storage drum. However, it can also be configured such that the rope drum is part of a drum winch. The drum winch includes a drum driver. The drum winch includes a controller. When the rope drum is implemented as part of a drum winch, all forces acting on the rope 2 are transmitted from the rope 2 to the rope drum.
[0051] In these embodiments, the winding device 40 includes a rope guide 5 ( Figure 1Rope 2 is supplied to rope drum 3 via rope guide 5. Rope guide 5 includes a pivot arm 6 and a deflection element 7. The pivot arm 6 is pivotable about a pivot axis 48. The pivot axis 48 is located in a plane oriented perpendicular to the rotation axis 50 and arranged between the two edge discs 4, particularly in the middle between the two edge discs 4. The direction of the pivot axis 48 is perpendicular to the rotation axis 50. The pivot axis 48 extends parallel to the tangent abutting the rope drum 3. The pivot axis 48 can be arranged at a distance from the drum of the rope drum 3. The pivot arm 6 is pivotable back and forth between the two edge discs 4 about the pivot axis 48. The two edge discs 4 are located in one of two planes G. The plane G is oriented perpendicular to the rotation axis 50. The two planes G respectively confine the edge discs 4 to their inner sides facing each other relative to the rotation axis 50. The pivot arm 6 is pivotable back and forth between these two planes G of the edge discs 4. The pivot arm 6 can be positioned relative to the rope drum 3 such that the pivotable portion of the rope guide 5 is arranged radially outside the edge disc 4, either partially or, as in these embodiments, entirely about the axis of rotation 50.
[0052] The pivot arm 6 has a rope window 34 ( Figure 2 Rope 2 is supplied to pivot arm 6 via rope window 34 at the longitudinal end of pivot arm 6 opposite to deflection element 7. Between rope window 34 and deflection element 7, rope 2 is guided along longitudinal axis 49 of pivot arm 6. Rope window 34 includes two guide rollers 35. Guide rollers 35 are rotatably supported at pivot arm 6. Guide rollers 35 are rotatable about roller axis 34. Roller axis 34 extends parallel to pivot axis 48 of pivot arm 6. Guide rollers 35 are arranged side-by-side. Guide rollers 35 constrain rope window 34 on opposite sides. Rope 2 passes between the two guide rollers 35. Rope 2 rests against the two guide rollers 35. Rope 2 is deflected by guide rollers 35.
[0053] The winding device 40 includes Figure 1Alternatively, the support element 36 shown in Figure 2. The support element 36 supports the pivotable portion of the rope guide 5. The support element 36 supports the pivot arm 6. The support element 36 is arranged such that it supports the pivot arm 6 at its longitudinal end opposite to the pivot axis 48. The support element 36 is arranged radially relative to the rotation axis 50 between the pivot arm 6 and the rope drum 3. The support element 36 extends its longitudinal extension in the direction of the rotation axis 50. The support element extends from one edge disc 4 of the rope drum 3 to the other edge disc 4. During the reciprocating movement of the pivot arm 6, the leverage force generated by the rotational motion of the rope drum 3 and transmitted to the pivot arm 6 via the deflection element 7 through the rope 2 is at least partially absorbed by the support element 36. In these embodiments, the support element 36 is a schiene. The support element 36 is fixed to the bracket 33 of the winding device 40. In these embodiments, the bracket 33 of the winding device 40 is formed from the base 19 of the rope drum 3. However, a winding device with a support structure separate from the rope drum can also be provided. An embodiment of the winding device without support elements can also be provided.
[0054] A deflecting element 7 is arranged at the pivot arm 6. The deflecting element 7 is located at the end of the pivot arm 6 opposite to the pivot axis 48. The deflecting element 7 is arranged such that the rope 2 passes in front of the pivot arm 6 when wound onto the rope drum 3. The deflecting element 7 is functionally positioned between the pivot arm 6 and the rope drum 3. The winding device 40 is designed such that the rope 2 is guided along the pivot arm 6. The rope 2 is guided from the pivot axis 48 to the longitudinal end of the pivot arm 6 facing the deflecting element 7. The rope 2 is guided along the pivot arm 6 from the rope window 34 to the deflecting element 7.
[0055] The deflection element 7 is tiltable about the tilt axis 47. The pivot arm 6 has a longitudinal axis 49. The tilt axis 47 extends along the longitudinal axis 49 of the pivot arm 6. The tilt axis 47 extends laterally (perpendicularly to the pivot axis 48 in this embodiment). The tilt axis 47 extends radially relative to the pivot axis 48. The tilt axis 47 is pivotable about the pivot axis 48.
[0056] After passing through the pivot arm 6, the rope 2 is supplied to the rope drum 3 via the deflection element 7. By pivoting the pivot arm 6 about the pivot axis 48, the rope guide 5 can be roughly pre-positioned. By tilting the deflection element 7, precise positioning can be achieved, especially in the area near the edge disc 4.
[0057] exist Figure 2In this configuration, the pivot arm 6 pivots such that the deflecting element 7 is located near the edge disc 4. The pivot axis 48 of the pivot arm 6 is arranged in the middle between the edge discs 4 about the rotation axis 50 of the rope drum 3. The central plane M extends perpendicular to the rotation axis 50. The central plane M contains the pivot axis 48. When the longitudinal axis 49 of the pivot arm 6 is located in the central plane M, the pivot arm 6 is positioned in the center. Figure 2 In the middle, the pivot arm 6 pivots from the center position through a pivot angle β.
[0058] On its path to the rope drum 3, the rope 2 enters the rope window 34 in the central plane M. As the pivot arm 6 pivots out from the intermediate position, the rope 2 deflects through the rope window 34. In these embodiments, this is accomplished by the guide roller 35.
[0059] exist Figures 1 to 7 In the position where the pivot arm 6 has pivoted through the pivot angle β, the deflection element 7 tilts from the basic position. In the basic position, the deflection element 7 guides the rope 2 such that the rope extends in plane E within the deflection element region, which includes the pivot axis 48 and the tilt axis 47. Figure 3 A view of the end face of deflecting element 7 along the direction of tilt axis 47 is shown. Rope 2 is guided within the region of deflecting element 7 in tilt plane F. Deflecting element 7 tilts from its basic position from plane E toward its tilt position into tilt plane F. Figure 2 and 3 In this configuration, deflecting element 7 is tilted by an angle γ about tilting axis 47. Tilt plane F is tilted by an angle γ relative to plane E. Tilt plane F includes tilting axis 47. Tilt plane F is tilted about tilting axis 47 relative to plane E. This tilting of deflecting element 7 relative to pivot arm 6 also... Figures 5 to 7 As shown in the image.
[0060] According to Figures 1 to 11 In this embodiment, the deflection element 7 is freely movable relative to the pivot arm 6. The tilting of the deflection element 7 is caused by the rope 2.
[0061] according to Figures 8 to 10 The schematic diagram shows the pivot arm 6 in its central position. Two other pivot positions of the sole pivot arm 6, or rope guide 5, are also schematically shown. For better illustration, the pivot arm 6 is not shown in its pivoted position from the central position.
[0062] Pivot arm 6 in Figures 8 to 10The two positions schematically shown are the edge positions of the pivot arm 6. Furthermore, the pivot arm 6 cannot pivot about the pivot axis 48. The winding device 40 has a limiting element 8. The limiting element 8 is arranged such that the pivoting movement of the pivot arm 6 about the pivot axis 48 is limited to a critical angle range Δ. The critical angle range Δ extends in a plane perpendicular to the pivot axis 48. The critical angle range Δ is a single continuous angle range. The critical angle range Δ is at most 135º, particularly at most 90º, preferably at most 70º, and in this embodiment at most 60º. The rope guide 5 has a pivotable portion about the pivot axis 48 with respect to the base 19. In these embodiments, the pivotable portion of the rope guide 5 includes the pivot arm 6 and the deflection element 7. Without the limiting element 8, the pivotable portion of the rope guide 5 would pivot about the pivot axis 48 between the edge discs 4 within a maximum edge angle range Ω. The edge angle range Ω is limited by the two edge discs 4. The inner sides of the two facing edge discs 4 lie in plane G. The edge angle range Ω is such that the pivotable portion of the rope guide 5 can pivot until it encounters the opposing planes G of the edge discs 4. When the pivotable portion of the rope guide 5 contacts plane G, the edge region of the edge angle range Ω is limited at that position by the position of the tilt axis 47. The maximum edge angle range Ω is measured in the basic position of the deflection element 7. Without the limiting element 8, the pivotable portion of the rope guide 5 would pivot about the pivot axis 48 within the maximum edge angle range Ω between the planes G of the edge discs 4.
[0063] The critical angle range Δ is less than the edge angle range Ω. The critical angle range Δ is at most 80%, particularly at most 75%, and in this embodiment at most 70%, of the maximum edge angle range Ω. The critical angle range Δ lies entirely within the edge angle range Ω. The region of the edge angle range Ω that does not overlap with the critical angle range Δ is called the angle range Φ. In these embodiments, the angle range Φ comprises two partial ranges. In these embodiments, the critical angle range Δ is arranged symmetrically about the central plane M. In these embodiments, the maximum edge angle range Ω is arranged symmetrically with respect to the central plane M. In these embodiments, the angle range Φ is arranged symmetrically with respect to the central plane M. The winding device 40 is designed such that the steering element 7 can tilt about the inclined axis 47, causing the rope 2 to be guided by the steering element 7 into the angle range Φ outside the critical angle range Δ.
[0064] In these embodiments, the limiting element 8 is implemented via a crank drive 18. The crank drive 18 includes... Figure 8 The shaft 11 is shown. Shaft 11 is rotatable about its centerline 46. In these embodiments, shaft 11 is driven by a worm gear transmission 20 (…). Figure 1The rope drum 3 is driven by a motor. However, it can also be configured such that a separate motor is used for the drive shaft 11. The motor used to drive the rope drum 3 is a hydraulic motor. However, it can also be any other type of motor. The motor drives the rope drum 3. In these embodiments, a transmission device (not shown) is arranged between the motor and the rope drum 3. The rope drum 3 is connected to the worm gear drive 20 via a chain drive 21. The gear of the chain drive 21 is torsionally connected to the worm shaft of the worm gear drive 20. The worm shaft is rotatably supported about the worm axis 43. Figure 1 and 4 The worm shaft meshes with a worm wheel (not shown) fixed at shaft 11. The rope winding device is designed such that when the rope drum 3 is in a specific pivot position relative to the axis of rotation 50, the rope guide 5 (particularly the pivot arm 6 of the rope guide 5) occupies a pivot position about the pivot axis 48 that depends on the position of rotation.
[0065] The crank drive 18 further includes an eccentric element 22. Figure 8 Eccentric member 22 is torsionally connected to shaft 11. At the longitudinal end of eccentric member 22 opposite to the axis 46, eccentric member 22 has a pin 12. Shaft 11 and eccentric member 22 allow pin 12 to move about axis 46. Pin 12 is torsionally connected to eccentric member 22. A connecting rod 13 is rotatably supported at pin 12. Connecting rod 13 connects pin 12 to bolt 23 of pivot arm 6. Connecting rod 13 is rotatably supported on bolt 23. Bolt 23 is torsionally connected to pivot arm 6. Bolt 23 is arranged at a distance d from the pivot axis 48. Figure 2 The distance d between the bolt 23 and the pivot axis 48 is at least 10%, advantageously at least 20%, and in these embodiments at least 25%, of the pivot length l of the pivotable portion of the rope guide 5, which is measured perpendicularly to the pivot axis 48 starting from the pivot axis 48. The bolt 23 is arranged on the longitudinal axis 49 of the pivot arm 6. Figure 8 The lengths of the connecting rod 13 and the eccentric element 22 determine the range of angles at which the bolt 23 and therefore the pivot arm 6 can pivot. In this way, the crank drive 18 forms the limiting element 8.
[0066] However, it can also be configured such that the limiting element 8 is formed by two simple pins, which are relative to the bracket 33. Figure 8 The pivoting movement of the pivot arm 6 is highlighted and restricted in this manner. In one embodiment variation, the winding device can be implemented entirely without forced guidance of the pivot arm or rope guide. Thus, the limiting element restricts only the free pivoting movement of the pivotable portion of the rope guide.
[0067] By limiting the pivoting motion of the pivot arm 6 to a critical angle range Δ and by providing tiltability of the deflection element 7 around the tilt axis 47, the winding device 40 can be compactly constructed while simultaneously providing a good winding image. Figure 15 A comparison is shown between a winding device 40 according to the invention and a winding device 41 according to the prior art. The two winding devices 40 and 41 are schematically drawn in a single figure relative to a single rope reel 3. The winding device 41 has a winding arm 42 with a non-tilting deflector element 37. The winding arm 42 is shown in two different pivot positions. In the pivot position where the winding arm 42 is near the edge disc 4, the rope touches the edge disc 4. The winding angle is 3º. In this pivot position, the wrap angle around the deflector element 37, which is configured as a single roller, is 75º.
[0068] According to the same invention Figure 15 The winding device 40 shown also has a deflection element 7 configured as a single roller. In this example, the diameter of the roller of the winding device 40 is equal to the diameter of the winding device 41. Figure 15 In this configuration, the pivot arm 6 is located in the edge region of the critical angle range Δ at the edge position. The wrapping angle around the deflection element 7 is also 75º. Compared to the pivot arm 6 of the winding device 40 according to the invention, the winding arm 42 of the prior art winding device 41 has a larger distance from the rotation axis 50 of the rope drum 3. The deflection element is tilted from its basic position about the inclined axis 47. The rope touches the edge disc 4. The winding angle is also 3º.
[0069] The pivot arm 6 of the winding device 40 according to the invention is significantly shorter than the winding arm 42 of the winding device 41 according to the prior art. However, the winding device 40 provides a good winding pattern and a winding angle of 3º. Due to the invention, the winding device 40 can be designed to be significantly more compact.
[0070] According to Figures 1 to 14 In one embodiment, the winding device 40 has a pivot drive 10. The pivot drive 10 is, for example, in... Figure 2 or Figure 8 As shown in the diagram, the winding device 40 is designed such that the pivot arm 6 can move back and forth within a critical angle range Δ via the pivot drive 10. In these embodiments, the pivot drive 10 includes a crank drive 18, a worm gear drive 20, and a chain drive 21. Alternatively, the winding device can be configured such that the pivot drive includes only a crank drive. Another embodiment of the winding device can be configured such that the pivot drive is implemented by a different type of circulating drive.
[0071] The pivot drive 10 is a component of the pivot actuator. The pivot actuator includes a motor. In these embodiments, the motor used to drive the rope drum 3 also drives the pivot drive 10. However, it can also be configured such that the pivot actuator includes a motor constructed separately from the motor of the rope drum 3. The pivot arm 6 is forcibly guided by the pivot actuator. However, it can also be configured such that the pivot arm 6 can move freely back and forth within a critical angle range Δ, particularly between the edge discs 4, without the actuator. Thus, the angular position of the pivot arm 6 is determined by the winding position of the rope 2 on the rope drum 3. The pivot arm 6 follows the rope 2, which is wound onto the rope drum 3 one loop at a time in the direction of the rotation axis 50.
[0072] According to Figures 1 to 11 In this embodiment, the pivot arm 6 is forcibly controlled, and the deflecting element 7 is freely movable relative to the pivot arm 6. The tilting of the deflecting element 7 is caused by the rope 2. According to Figures 1 to 11 The rope winding device is designed so that when the rope 2 is wound onto the rope drum 3, it travels a greater distance in the direction of rotation axis 50 compared to the distance traveled by the free end of the pivotable portion of the rope guide 5 in the direction of rotation axis 50 due to pivoting around pivot axis 48. In its... Figure 2 The deflecting element 7 is inclined via the rope 2 at the front (vorauseilend) along the path from the center plane M to one of the two edge regions of the critical angle range Δ, specifically to one of the two edge disks 4. The deflecting element 7 is about... Figure 3 The inclination of the basic position in plane E shown continuously increases here. The inclination of deflecting element 7 is greatest at the return point of pivot arm 6. In the edge region of deflecting element 7 from the critical angle range Δ, especially on the path from edge disk 4 to center plane M, the inclination of deflecting element 7 with respect to its basic position in plane E decreases. When rope 2 is wound out from rope drum 3, the drum of rope drum 3 rotates in the opposite direction about the axis of rotation 50. The steps described for winding are performed in reverse order. Deflecting element 7 is tilted by subsequent rope 2.
[0073] In these embodiments, the pivot drive 10 includes the crank drive 18 already described. Accordingly, the pivot drive 10 has a shaft 11 rotatable about a centerline 46, a pin 12 eccentrically arranged relative to the centerline 46 and movable about the centerline 46, an eccentric element 22, a connecting rod 13, and a bolt 23. The pivot arm 6 is forcibly guided by the pivot drive 10, which is part of the pivot actuator. The pivot drive 10 causes the pivot arm 6 to... Figure 8 It moves back and forth between the edges of the critical angle range Δ shown. In this embodiment, the centerline 46 extends parallel to the pivot axis 48. According to... Figures 1 to 13In one embodiment, the eccentric member 22 guides the pin 12 on a circular track around the axis 46.
[0074] The force of the motor is transmitted to the pivot arm 6, in particular, through the transmission device, through the rope drum 3, through the chain drive 21, through the worm gear drive 20, and through the crank drive 18.
[0075] The pivot drive is reversible. The two layers of rope 2 on the rope drum 3 correspond to one revolution of the crank drive 18. The pivot drive 10 includes a worm gear drive 20 and a chain drive 21. The total gear ratio of the worm gear drive 20 and the chain drive 21 is approximately twice the number of rope turns on one rope layer. In these embodiments, the total gear ratio for reduction is approximately 20 to 50.
[0076] The overall transmission ratio can be adapted based on the number of rope turns on a single rope layer. Therefore, a rope spool 3 with a length greater or less than the direction of the rotation axis 50 can be used. In these embodiments, the overall transmission ratio is adapted by adjusting the transmission ratio of the chain drive 21. The transmission ratio of the chain drive 21 can vary between 1:1 and 2.5:1. In this case, the rotational speed is reduced by the chain drive 21.
[0077] Figure 14 An alternative implementation scheme is shown in the figure. Figure 14 The winding device 40 is designed such that the distance 'a' between the axis 46 and the pin 12 varies as the pin 12 moves around the axis 46. In an alternative design for the crank drive, the crank drive has a rotating disk 24 and a cam disk 14 instead of an eccentric element. The cam disk 14 is torsionally fixed to the winding device 40. Figure 14 The base 19 (not shown) is rotatably supported relative to the cam disk 14. The rotating disk 24 is located at... Figure 14 Shown in dashed lines. The rotating disk 24 has an elongated hole 25. The elongated hole 25 is an opening that completely penetrates the rotating disk 24 along the axis 46. The elongated hole 25 has a longitudinal extension. The longitudinal extension of the elongated hole 25 extends radially along the axis 46. The length of the longitudinal extension of the elongated hole 25 is several times the diameter of the pin 12. The pin 12 is inserted through the elongated hole 25. The pivoting transmission device 10... Figure 14 The shaft 11 (not shown) is torsionally connected to the rotating disk 24. When the shaft 11 rotates, the rotating disk 24 also rotates. The pin 12, which passes through the elongated hole 25, is driven by the edge of the elongated hole 25. The pin 12 is fixed to the connecting rod 13.
[0078] The cam disk 14 has a track 15. The track 15 completely penetrates the opening of the cam disk 14 in the direction of the axis 46. The track 15 is closed around the axis 46. A pin 12 is inserted through the track 15 in the direction of the axis 46. Viewed in the direction of the axis 46, the track 15 and the elongated hole 25 overlap. The pin 12 is inserted through both the track 15 and the elongated hole 25 in the direction of the axis 46. As the rotating disk 24 rotates around the axis 46, the pin 12 is driven by the elongated hole 25 and guided in the track 15 around the axis 46. The track 15 guides the pin 12 on its path around the axis 46. In this case, the distance 'a' between the pin 12 and the axis 46 is variable. The track 15 is designed such that it causes a change in the distance 'a' of the pin 12.
[0079] The spacing 'a' varies according to the angular position of the rotating disk 24 as it passes through the track 15, resulting in a constant rope pitch as the rope is wound onto the rope drum 3. The rope winding device is designed such that the pivot arm 6, during one revolution of the rope drum 3 around the rotation axis 50, offsets the rope 2 in the direction of the rotation axis 50. Figure 6 The rope diameter c shown is 100% to 110%, particularly 100% to 105%, and in this embodiment, 100% to 102%. This is particularly applicable in accordance with... Figure 12 and 13 The case where the alternative crank drive is used in the winding device 40. According to... Figure 14 The crank drive mechanism can also be used according to Figures 1 to 13 In the embodiments described above.
[0080] Regardless of the precise design of the crank drive mechanism, based on Figures 1 to 13 In one embodiment, the pivotable portion of the rope guide 5 can pivot about a pivot axis 48. As described above, it is also conceivable that the pivotable portion of the rope guide 5 is not forcibly controlled but can pivot freely. Figure 2 As shown, the pivotable portion of the rope guide 5 has a pivot length l measured perpendicularly to the pivot axis 48, starting from the pivot axis 48. The edge discs 4 each have a maximum diameter measured perpendicularly to the rotation axis 50. The larger of these two diameters is referred to as the maximum diameter d. The pivot length l of the pivotable portion of the rope guide 5 is at most 100% of the maximum diameter d, particularly at most 95%, and in this embodiment at most 90%.
[0081] Figure 11 A deflection element 7 is shown. The deflection element 7 has a rope inlet 26. A rope 2 is supplied to the deflection element 7 through the rope inlet 26. The deflection element 7 has a rope outlet 27. The rope 2 exits the deflection element 7 at the rope outlet 27. The rope 2 deflects within the deflection element 7.
[0082] In the prior art, a single deflection roller is typically used for this purpose. When the rope deflects at approximately 90°, a wrap angle of approximately 90° for the single roller is also required. If the radius of the single roller is chosen to be too small, excessive and rapid wear of the rope may occur. On the other hand, a larger radius for the single deflection roller requires more installation space and hinders its arrangement at the desired small radial distance from the rope drum.
[0083] In the case of the deflection element 7 according to these embodiments, a plurality of rollers 16 are provided. These rollers 16 are arranged on a curved track 17. The rollers 16 are rotatably supported at the base 28 of the deflection element 7. The rollers 16 are arranged directly side by side on the curved track 17. The wrap angle of the rope 2 around the single roller among the plurality of rollers 16 is less than 30º, particularly less than 20º, and in this embodiment less than 10º. In this embodiment, six rollers 16 are provided. The curved track 17 can mimic a circular line. In this embodiment, the curvature of the curved track 17 is greater than the curvature of a circular line passing through the rotation axes of the two outermost rollers, the central axis of which extends parallel to the rotation axis. The spacing between the individual rollers 16 is less than 100% of the diameter of the smallest roller 16, particularly less than 50%, and in this embodiment less than 5%. In this embodiment, the rollers 16 are of the same diameter. In the deflection element 7, the rope 2 is guided from the rope inlet 26 to the rope outlet 27 on the deflection rollers 16. The base 28 restricts the guiding space for the rope 2 on both sides of the rope 2 in the direction of the rotation axis of the roller 16.
[0084] Figure 12 and 13 Alternative embodiments of the winding device 40 and the rope winding device are shown respectively. According to... Figure 12 and 13 The winding device 40 and according to Figures 1 to 11 The only difference in the winding device is that it additionally includes an adjustment device 9. According to Figure 12 and Figure 13 The remaining components of the winding device 40 and according to Figures 1 to 11 The components of the winding device 40 are implemented in the same manner. Correspondingly, the same reference numerals are also used.
[0085] The deflecting element 7 is arranged in an inclined position about the tilt axis 47. The pivot arm 6 is arranged in a pivot position about the pivot axis 48. According to... Figure 12 and 13 The winding device 40 is designed such that the adjusting device 9 presets the tilt position of the deflection element 7 according to the pivot position of the pivot arm 6. Figure 12In one embodiment, the adjusting device 9 includes a linkage guide 29, a linkage pin 30, and a tilting element 31. The tilting element 31 is torsionalally connected to a tiltable deflector element 7. The linkage pin 30 is fixed to the tilting element 31. The linkage pin 30 protrudes beyond the tilting element 31 in the direction of the tilt axis 47. The linkage pin 30 is eccentrically arranged relative to the tilt axis 47. The linkage pin 30 has a distance from the tilt axis 47 measured in the direction of the rotation axis 50. The linkage pin 30 has a distance from the deflector element 7 measured in the direction of the rotation axis 50. The linkage pin 30 is inserted through a linkage track 32 of the linkage guide 29. The linkage track 32 is an opening in the linkage guide 29 that completely penetrates the linkage guide 29 in the direction of the tilt axis 47.
[0086] like Figure 13 As shown, the tilt axis 47 can pivot about the pivot axis 48 in the pivot plane S. The pivot plane S is perpendicular to the pivot axis 48. If the deflecting element 7 is located in the central plane M between the edge disks 4, the connecting pin 30 is arranged with its central axis in the pivot plane S. The connecting rod track 32 extends obliquely relative to the pivot plane S. When the deflecting element 7 pivots out of the central plane M, the connecting pin 30, in particular the central axis of the connecting pin 30, moves out of the pivot plane S due to the guidance of the connecting pin 30 in the connecting rod track 32 of the connecting rod guide 29. Since the connecting pin 30 is eccentrically fixed at the tilting element 31 relative to the tilt axis 47, the tilting element 31 tilts when the connecting pin 30 deviates from the pivot plane S. When the pivot arm 6 pivots about the pivot axis 48 from the central plane M toward one of the two edge regions of the critical angle range Δ, in particular one of the two edge disks 4, the deflecting element 7 continues to tilt further about the tilt axis 47. The linkage track 32 has a continuous direction. However, a linkage track with a discontinuous direction can also be provided, which causes a sudden change in the tilt position of the deflection element 7.
[0087] The adjusting device 9 causes the correlation between the tilt position of the deflecting element 7 and the pivot position of the pivot arm 6. The adjusting device can also be implemented in any other conceivable manner. For example, a separate drive can be provided for the tilt of the deflecting element 7, which is coordinated with the pivot drive via a control unit. It is also conceivable that the tilt position of the deflecting element 7 is achieved through a drive connection with the pivot drive. Forced control of the tilt of the deflecting element 7 can also be achieved, for example, by a thrust member that is tilted about an axis parallel to... Figure 13 The line of intersection between the center plane M and the pivot plane S shown extends as illustrated. In this case, the base point of the deflection element can only be on a plane parallel to... Figure 13The pivot plane S shown moves within the plane. As the thrust member pivots, its length changes. The deflecting element 7 pivots about the pivot axis of the thrust member to the same degree as the thrust member.
