Technical Field

The present invention relates to a method for operating a slewing winch according to the preamble of claim 1. The invention further relates to a corresponding slewing winch as a device.

Background

Such a slewing winch is known in principle from the prior art, i.e. for example from japanese patent document JP 64-5625. The slewing gear disclosed there has a rotor, at which at least one gear spindle is mounted, the rotor-side end of which is eccentric to the axis of rotation of the rotor. A slewing winch is used to wind a belt, in particular a metal belt, onto its winch spindle. At the beginning of the winding process, the rotor of the winch spindle is first rotated such that the still empty winch spindle is positioned in the unwinding position. In this position, the strip is then first unwound onto the winch spindle. After the unwinding, that is to say after winding about 1 to 3 coils of the strip onto the capstan mandrel, a tensile stress is built up in the strip for the further winding (strip tension). During continued winding, the winch spindle is rotated from said unwinding position to a winding-complete position. Where the tape is wound to complete a coil or bundle. The coil can then be removed from the winding-complete position after completion and transported further. In this way, the slewing winch typically has two winch spindles which are fixed to the rotor of the slewing winch eccentrically to the axis of rotation of the rotor and can be pivoted alternately between the unwinding and winding-completion positions. This enables an extremely short bundle connection sequence (bundfoldesequenzen). It is also known from said japanese document that a following mandrel support is assigned to the free end of the winch mandrel, which following mandrel support is coupled to the free end of the winch mandrel in the unwinding position and remains coupled at its free end during the transfer of the winch mandrel from the unwinding position to the winding-up completion position. In this regard, the term "follower mandrel support frame" means that it follows during transit.

The winch spindle typically already has a very high self weight. Thus, its free end, even when it is not wound with a metal strip, hangs down or hangs down, typically 1 to 2mm, with respect to its rotor-side end. In the case where the load and the bundle weight are increased by the belt tension, such deformation of one side becomes severe.

This sagging or hanging of the free end is disadvantageous in this respect, since it reduces the permissible loading of the winch spindle and, in addition, reduces the winding accuracy of the winding on the winch spindle. When winding the web, so-called "cratering formation" is therefore often caused, i.e. the individual turns of the web are offset from one another in an accordion-like manner. Finally, the strap tension for stable winding also builds up relatively late, i.e. only slowly after unwinding of a few coils of the strap, for the suspended free end of the winch spindle, which in addition leads to inaccuracies in winding the strap. Based on the coil accuracy mentioned, it is conventionally generally stated that the not inconsiderable parts of the metal strip wound into a coil are scrap. This course of the tape and the "shrinkage cavity formation" associated therewith have an additional influence on the flatness measurement and adjustment of the tape head.

The following mandrel support frames known from said japanese patent application do not appear suitable for eliminating these known drawbacks, since they support the free end of the winch mandrel not mainly against gravity but obviously mainly against the belt tension. This is obvious to the person skilled in the art that the two-part carrier head of the following mandrel support surrounds and stabilizes the surrounded winch mandrel not in the vertical direction but mainly in the horizontal direction.

Disclosure of Invention

The object of the present invention is to improve the known method for operating a slewing winch and the known slewing winch in such a way that bending or hanging-up of the free end of the winch spindle is avoided, in particular at the beginning of the unwinding process.

The object is achieved by the method claimed in claim 1. The winch spindle is characterized in that the free end of the winch spindle is raised in the uncoiled position against the force of gravity to the height of its rotor-side end by means of a detachably coupled follower spindle support.

By lifting the free end of the winch spindle in the claimed manner, its lowering or lifting is compensated for and all the above-mentioned disadvantages are thereby avoided. In particular, shrinkage cavity formation during winding of the metal strip can be avoided thereby (totnebildung). In addition, the rapid build-up of the strip tension achieved thereby ensures that the individual coils of the strip of the coil are stacked closely on one another. By means of the free mandrel end being supported, the strip tension can assume an increased value in the unwinding position compared to the unsupported mandrel end.

According to a first embodiment of the method according to the invention, it is advantageous if the free end of the winch spindle has been lifted before and/or during the unwinding of the strip in the unwinding position. When the free end has been lifted before the unwinding of the strip begins, the shrinkage cavity formation can thereby already be prevented when the strip is unwound. In principle, the following are used: the earlier the lifting is, the better the winding result. The less scrap is produced by the winding process.

Advantageously, the free end of the winch spindle is permanently held at the changing height of its rotor-side end by means of the coupled following spindle support frame during the transfer of the winch spindle from the unwinding position to the winding-completion position (even in view of the increased coil weight here). This ensures a flush winding of the strip with the rings lying closely against one another even during the continued winding process during the transfer of the winch spindle.

Claims 1 to 4 discussed so far are directed only to compensating for the force of gravity, so that according to the method steps first only the lowering of the free end of the winch spindle due to the force of gravity is counteracted, which is reflected in that the free end of the winch spindle is raised to the "level" of its rotor-side end.

However, in addition to gravity, the winch spindle and in particular the free end thereof are also subjected to at least one force component in the horizontal direction based on the belt tension to which the belt is subjected during winding. The free end of the winch spindle is thereby also bent in principle in the horizontal direction. Such bending in the horizontal direction is also undesirable, since it likewise leads to the described failure of the band when it is wound onto the winch spindle.

The invention therefore advantageously provides that the free end of the winch spindle is also permanently held against the end on the rotor side thereof by means of the following spindle support frame already in the unwinding position and also during the transfer of the winch spindle from the unwinding position to the winding-complete position (even when taking into account the belt tension which increases here and changes in its direction and in its value). The expression "end opposite the rotor side" means that the free end of the winch spindle is not only at the level of the rotor-side end, but that the winch spindle is also not bent in a horizontal plane. This is ensured according to the invention in that the following mandrel support is configured not only to counteract the gravitational force and to correct the height of the free end of the winch mandrel, but also to counteract the belt tension.

In order to synchronize such movements and to calculate the specific support position and support force of the following spindle supports, a calculation unit is provided. This is determined by the changed parameters of the support position, which generally correspond to the current position of the free end of the winch spindle: the gravity, the belt tension, the current position of the mandrel and the rotation process are calculated, and the supporting position is occupied by the follow-up mandrel supporting frame. The resulting force and thus the changed amount of the deviation of the free end of the winch spindle from the fixedly mounted end of the winch spindle results from the changed load parameters gravity and the strap tension. This ensures that the movement performed by the adjusting mechanism is not only performed synchronously with the position of the spindle during the swiveling process, but also takes into account the changing load parameters and thus causes the free end of the winch spindle to be always raised to the height of its rotor side. The synchronization can be performed by electrical and/or mechanical components/structures.

Advantageously, the winch mandrel is additionally supported in the winding-completed position with the coil typically wound thereon by means of a fixed mandrel support frame. After the fixed mandrel support has performed its supporting function, the following mandrel support can be disengaged and moved back into the unwinding position. The coil can be wound in a supported manner in the winding-completed position by means of a fixed mandrel support. Next, the completed roll can be carried away, typically using a bundle transport vehicle.

The above object is achieved by a slewing winch as claimed in claim 7. It is characterized in that the following mandrel support frame is supported on the ground of the preferably car lobby and the adjusting mechanism is configured such that the support head together with the coupled free end of the winch mandrel is lifted against the force of gravity to such an extent that the free end of the winch mandrel is at the level of the rotor-side end of the winch mandrel when the winch mandrel is in the unwinding position.

Detailed Description

The present invention will be described in detail below in the form of embodiments with reference to the accompanying drawings. Throughout the drawings, elements of the same technology are denoted by the same reference numerals.

Fig. 1 shows a slewing winch 100 according to the invention. It is essentially formed by a rotor 110 (i.e., a disk which rotates here by way of example), on which two winch spindles 112 are mounted, the rotor-side ends of which are eccentric to the axis of rotation D of the rotor. The two winch spindles 112 extend substantially perpendicularly to the plane of the rotor. Each of these two winch spindles serves for winding the strip 200, in particular a metal strip, into a coil. The winch spindle 112 shown on the left in fig. 1 is in the so-called unwinding position a, while the second winch spindle 112 is in the so-called winding-complete position. The way in which the slewing winch operates and the method according to the invention continue to be described below.

According to fig. 1, in the working position a the winch spindle 112 is equipped with a following spindle support 120. The mandrel support frame 120 has a cradle head 122 that is releasably coupled to the free end of the winch mandrel 112. The free end of the winch spindle is opposite the end located on the rotor side of the winch spindle, which is mounted with the rotor-side end on the rotor 110.

The follower mandrel support frame 120 sits and is supported on the ground 300, such as a workshop hall, or on a pedestal. In particular, it has an adjusting mechanism 124, for example in the form of a double parallel crank drive, for moving the carrier head 122 of the support carrier on a track, in particular a circular track, which is predetermined by the structure of the adjusting mechanism. This circular path is indicated in fig. 1 by an arrow to the right, on which the left winch spindle can be moved from the unwinding position a into the winding-complete position F by a rotation of the rotor 110 about its axis of rotation D and at the same time by a suitable movement of the adjusting mechanism 124 by following up of the spindle support.

This situation is shown in fig. 2. It can furthermore be seen there that the winch spindle 112 is initially supported in the winding-complete position F not only by the following spindle support 120, but initially additionally also by the fixed spindle support 130. In this winding-completed position F, the fixed mandrel support does not have to support only the winch mandrel, but additionally also the roll togetherThe completed coil is wound. In this case, fig. 2 shows that the fixed mandrel support 130 is positioned and designed such that it can be placed further inside the winch mandrel than the carrier head 122 of the following mandrel support in order to support the free end of the winch mandrel 112. "more inwardly" means here "closer to the rotor 110", however always still at the free end of the winch spindle. This arrangement and positioning of the fixed mandrel support 130 with respect to the follower mandrel support 120 is important to achieve disengagement of the bracket head 122 from the free end of the winch mandrel 112 in the wind-up complete position. Since the fixed mandrel support 130 is positioned more inwardly at the free end of the winch mandrel 112, the region in front of the bracket head 122 is left free, so that the bracket head can be easily detached for interference edges without problemsThe follower mandrel support frame is disengaged.

Fig. 3 shows an embodiment of a holder head 122 for a follower mandrel support 120. It can be seen that the bracket head 122 is of sleeve-like design at its end facing the winch spindle 112. In or on this sleeve-like end, a sliding sleeve 128 is mounted so as to be movable axially in the direction of the double arrow. In order to couple the support head 122 to the free end 113 of the winch spindle 112, the sliding sleeve is slid onto the protruding end 113a of the free end of the winch spindle and is locked in this position by means of a handling element 129, for example a cylinder. The actuating element 129 is also used to retract the sliding sleeve and thus to release the free end of the winch mandrel from the holder head 122 or from the following mandrel support. In the coupling position shown in fig. 3, the free end 113 of the winch spindle 112 is rotatably supported within the sliding sleeve 128 or within the sleeve-like end of the support head 122. At the same time, however, the sleeve-like end design ensures that the free end 113 of the winch spindle is supported at each point of the orbital curve mentioned above with reference to fig. 1 against the weight G of the following spindle support.

The method according to the invention for operating the slewing winch 100 according to the invention described above is explained in more detail below with reference to fig. 4 to 6.

The method first provides that the rotor 110 of the slewing winch 100 is rotated in order to move the first empty winch spindle 112 into the unwinding position a, see fig. 1. In the uncoiled position a, the cradle head 122 of the follower mandrel support frame 120 is then disengageably coupled to the free end of the winch mandrel 112. This state is also depicted in fig. 4.2.

The idea on which the method according to the invention is based, however, is shown in fig. 4.1. In the schematic illustration, it can be seen that the end face of the winch spindle 112 is in the unwinding position a. The small circles drawn with a dot-dash line here show the rotor-side end of the winch spindle fixedly mounted on the rotor 110, while the small circles drawn with a continuous line show the free end of the winch spindle. The deviation shown in the exaggerated illustration between the two small circles marks a sagging or lowering of the free end of the winch spindle 112 relative to its rotor-side end, wherein a sagging of, for example, approximately 1 to 3mm would have been carried out only on the basis of the high dead weight of the winch spindle 112. This sagging of the free end of the winch spindle leads to an imprecisely wound coil as described at the outset.

This sagging of the free end 113 of the winch spindle 112 is therefore counteracted according to the method according to the invention in such a way that this free end 113 is lifted by means of the coupled following spindle support shelf against the force of gravity G to the level of the rotor-side end of the winch spindle 112.

Fig. 4.2 shows the free end of the winch spindle 112 in the raised position, wherein it can be seen that in fig. 4.2 the rotor-side end of the winch spindle 112 and the free end are shown overlapping.

Starting with this in the unwinding position a, the tape is wound onto the winch spindle 112. This is initially carried out completely without any belt tension, which is established only when the belt, in particular a metal belt, is wound in several windings (typically 1 to 5 windings) on the winch spindle 112 and can be subjected to an applied tensile stress or an applied belt tension.

Preferably, the free end 113 of the winch spindle 112 is already raised to the level of the rotor-side end before and/or during the unwinding of the strip in the unwinding position a. In a possible case, the free end of the winch spindle should already be raised to the level of the rotor-side end before the unwinding begins, since the problems described at the outset in winding the strip can already be avoided from the beginning.

Fig. 4.3 shows the components of the strip tension which are also in the uncoiled position a, where they are indicated by two arrows aligned with one another parallel to the strip 200. In fig. 4.2 and 4.3, the double parallel crank drive 124 of the following spindle support holds its support head and thus also the free end 113 of the winch spindle 112 at the level of the rotor-side end in the unwinding position.

Fig. 4.4 shows the winch spindle 112 together with the partially wound strip 200 with the strip tension in its transfer from the unwinding position a into the winding-complete position. Here, too, according to the method according to the invention, the adjusting mechanism 124, here in the form of a double crank gear, for example, always keeps the free end 113 of the winch spindle 112 at the level of the rotor-side end of the winch spindle. At the same time, the adjusting mechanism 124 also counteracts the belt tension at the free end of the winch spindle, so that no lateral deviations occur between the two ends of the winch spindle 112. More precisely, it is ensured in particular by the adjusting mechanism 124 that the free end of the winch spindle is always held opposite the rotor-side end of the winch spindle. In this way, it is ensured that the band 200 is wound exactly onto the coil and does not have the disadvantages described at the outset.

Fig. 4.5 shows the winch spindle 112 in the winding-complete position F together with the coil diameter increased during this. The adjustment mechanism 124 is suitably rotated accordingly.

Fig. 4.6 shows the winch spindle 112 in the winding-completed position F, where the free end 113 of the winch spindle 112 is now also supported by the static or fixed spindle support 130. In this winding-completed position, the fixed mandrel support 130 alone takes up the support of the free end of the winch mandrel, so that the following mandrel support, for exampleCan be disengaged from the free end by pulling back the pusher sleeve 128. The detached following mandrel support can thus be moved into the unwinding position again, as shown in fig. 4.7. The coil can be wound to completion and then removed from the winch mandrel without interfering edges with the following mandrel support

Fig. 5 again shows a different scenario in which the winch spindle has already been known from fig. 4.1 to 4.7 in its transfer from the unwinding position a to the winding-complete position F. In fig. 5, it is particularly evident that the acting forces which have already been indicated in fig. 4.1 to 4.7 can also be recognized. The resultant or resultant force FRES acting on the winch spindle 112 is given as the vector sum of the weight force FG and the tension force Fz based on the belt tension. It can be recognized that the gravitational force FG acting always in the vertical direction is also relatively small in the unwinding position a and becomes always larger toward the winding completion position. This is explained by the fact that in the uncoiled position a, only a part of the dead weight of the winch spindle 112 at the free end has to be supported and lifted by the following spindle support frame. During the transfer into the winding-complete position, at the same time more and more of the band 200 is wound onto the winch spindle, whereby the weight force FG increases all the time until it consists of a portion of the weight force of the coil and the self weight of the winch spindle in the winding-complete position. Furthermore, fig. 5 makes it possible to recognize that the pulling force FZ increases in number from the unwinding position a to the winding completion position F and changes in direction, in particular, however, as well. When vector-combined with the described weight force FG, different resulting forces FRES, respectively, are thereby generated, which are illustrated in fig. 5. The follower spindle support 120 according to the invention must in particular be configured to react said resulting resultant force FRES. To this end, in accordance with the present invention, the follower spindle support 120 is supported on the ground for directing force into the ground.

The resultant force and the current pivot position are calculated by a not shown calculation unit, which specifies the occupied support position of the following spindle carrier and can be implemented by the adjusting mechanism.

Fig. 6 again shows the position of the winch spindle already described in part with reference to fig. 4.1 to 4.7 during its transfer from the unwinding position into the winding-complete position. Fig. 6 shows in particular different possibilities for positioning the drive 126 in the hinge point of the double crank drive 124. The drives are each represented by a segmented assignment of the hinge points. In principle, it is sufficient to provide only one drive in one pivot point, as is shown in fig. 1 by way of example and alternatively for the two pivot points in the second column. It is better, but also more expensive, to mount the two drives 126 in different hinge points of the double crank transmission 124, as this is shown in the third column in fig. 6. In the embodiment shown in fig. 3 and in the position of the winch spindle 112 shown there, a rotation direction of the drive 126 in the same direction is suitable. Here, the winch spindle 112 is also before the dead center. The rotational moments applied by the two drivers 126 add up.

In the exemplary embodiment shown in the fourth column of fig. 6, the winch spindle 112 is located opposite a dead center, and the rotational torques applied by the two drives 126 act individually and in opposite rotational directions.

The flexibility of the winding process is advantageously significantly increased by the method and the device according to the invention. The number of possible turns in the unwinding position and the permissible tape tension value in the unwinding position can be increased, and the speed during the revolution can be changed. The winding process can thereby be carried out in a significantly more flexible manner.
