Description

The The invention relates to a device for winding and unwinding strand-like Winding material, wherein the device rotatably mounted about an axis of rotation Winding drum, one provided with a cross thread, to the axis of rotation spaced guide axis, one on the guide axis longitudinal the guide axis reciprocable guide element and a hold-down, at least when rolling up the Wickelguts on the winding drum, the winding material on the outer circumference of the guide element suppressed.

From the DE-G 85 26 244 For example, a cable drum for an electric cable is known, which has a rotatably mounted winding drum and a guide element which is displaceably arranged along a guide axis. In this case, the guide axis is arranged parallel to the axis of rotation of the winding drum. In order to achieve guidance of the winding material, the guide element must be manually moved back and forth along the guide axis. In addition, the winding material grinds both during winding and unwinding over the U-shaped design guide element and a handle axis forming the handle. As a result, an increased wear of the winding material occurs. In addition, the guide element must be manually moved back and forth.

Furthermore, from the DE-G 94 01 104 a hose carriage is known, which has a along a threaded rod designed as a guide axis and forth movable guide element. The winding drum is movable via a hand crank. About gear wheels and a power transmission belt, the guide shaft is rotated in response to the winding drum in rotation and thus causes a displacement of the guide element along the guide axis. This device has the disadvantage of a very complex construction.

A device for winding and unwinding of strand-like winding material of the type mentioned is from the DE 103 00 960 A1 known. In the known device, the hold-down device is designed as a simple rod, which is arranged at a fixed distance from the outer circumference of the guide element. Although it is mentioned in this document that the distance of the hold-down to the guide axis and to the outer periphery of the guide element is adjustable. However, this only serves to adapt the hold-down to winding material of different thickness and thus to prevent jumping out of the winding material optimal. The distance of the holddown is at most once adapted to the thickness of the winding material and remains unchanged over the entire useful life of the device, since the wound on the winding drum winding material over the useful life of the device is usually not replaced, especially not exchanged for a winding material with a different thickness becomes. It is not contemplated to adjust the hold-down during the useful life of the device, eg. For easier unwinding of the winding material. That would not even be possible in the known device, since only a retaining element of the blank holder would have to be solved by means of a suitable tool in a time-consuming procedure.

task The invention is a device of the type mentioned To design and further develop, on the one hand, the winding material while rolling up safely and reliably on the outer circumference holds the guide element and on the other hand but also facilitates the unwinding of the winding material.

outgoing from a device of the type mentioned is the object solved by the hold-down device is pivotable between two positions is, namely a first position in which the hold down the winding material on the outer periphery of the guide element pushes and a second position in which the hold-down a greater distance to the outer circumference of the guide element as in the first position.

Advantages of the invention

The invention makes it possible during the winding of the winding material to bring the hold-down in the first position and to press the winding material on the guide element, so that this is safely and reliably brought into a rotational movement and reciprocated on the guide shaft. The winding material is rolled up evenly distributed on the winding drum. For unwinding of the winding material of the hold-down is simply brought into the second position, that is, the distance between downholder and outer peripheral surface of the guide element increases. As a result, the winding material can be handled much easier and faster from the winding drum, especially when it is simply pulled to unwind at the unwound end of the winding material. For unwinding, the winding material can be removed completely from the guide element and at the end of unwinding easily reinserted into the guide element, wherein the increased distance between hold-down and guide element greatly simplifies the removal of the winding material and insertion into the guide element. Alternatively, the winding material can be easily left in the guide element, wherein the greater distance between hold-down and guide element allows easier and faster unwinding of the winding material. This is achieved in particular by the fact that Wi ckelgut in the second position of the blank holder does not rub against the hold-down and / or the peripheral surface of the guide member along, but can be handled almost without resistance.

According to one advantageous development of the invention it is proposed that the hold-down is formed as a cover, which has an upper Covering the peripheral region of the guide element. This will be the area of the guide axis and / or leadership Protected against dirt and moisture from above. This always provides a smooth and moving the guide member on the guide axis for sure. This development is particularly in the use of the device according to the invention in dirt and moisture endangered Areas, for example. On a construction site or in the outdoor area of importance.

Advantageously covered the cover viewed from above at least the guide axis completely. Logically, At least the areas of the guide axis should be covered be that the guiding element while of his float. This embodiment in particular, concerns the breadth of the proposed coverage. Preferably covered the cover viewed from above at least the guide element Completely. This embodiment in particular concerns the depth of the proposed coverage. Preferably, the cover is in the manner of a cylinder jacket section domed educated, being the imaginary longitudinal axis the cylinder jacket is parallel to the guide axis.

According to one preferred embodiment suggested that the hold-down between the first and the second position is pivotable about a pivot axis in the essentially parallel to the guide axis runs.

Around ensure that the hold down the winding material safely and reliable on the outer peripheral surface of the leadership suppressed, It is suggested that the hold down at least in the first Position detachable is held. Advantageously, the hold-down is at least in the first position by means of a latching or snap connection solvable held. Preferably, the device has at least one support or holding element on which the guide shaft is attached and at which the hold-down releasably held at least in the first position is. It is proposed that at least one yielding to the support or holding element Projection is formed, at least in the first position of the hold-down with a corresponding, on the hold-down trained depression engages. According to a preferred embodiment the resilient projection formed in the support or holding element Bore and held in the bore under spring load ball.

According to one Another advantageous development of the invention is proposed that the external thread is designed as a cross thread and the cross thread a left-hand thread with a first pitch angle and a right-hand thread with a second pitch angle includes.

advantageously, is the guide element as a leadership role formed, which leads the winding material during winding and unwinding, wherein the winding material during winding and unwinding by friction with the guide roller engages and this in a rotational movement about the guide axis added.

The Device allows, for example, a cable particularly evenly characterized unwind and unwind that the guide element automatically during winding or unwinding of the cable across the width of the winding drum is led back and forth. When winding the winding material is evenly distributed on the winding drum. In order to on the one hand, the available on the winding drum so-called changing room optimally used. On the other hand, it will Prevents entanglement on the winding drum that when unwinding the winding material, a winding of a subsequent superimposed that the unwinding is made difficult at this point.

The guide element is preferably as a guide role designed. Furthermore has the leading role on the inner circumference of a runner on, which is aligned about an axis perpendicular to the guide axis axis of rotation is rotatable. It is on the directed to the guide axis surface of the runner formed a female threaded portion. The trained on the runner Internal threaded section allows it that the leadership on the guide axis along the guide axis especially simply by the fact that the leadership is placed in a rotational movement about its axis of rotation.

The rotor may assume the first pitch angle and the second pitch angle by rotation about a rotation axis. Reached the rotor and thus the leadership of an outer boundary of the cross thread, the rotor is rotated by a there changing pitch angle of the outer thread of the guide roller along its axis of rotation such that the rotor - and thus the guide roller - a first thread crossing second thread in the now opposite direction to the opposite end of the guide axis follows. This allows a particularly simple way an automatic back and forth tion of the leadership role in winding and unwinding of the winding material.

Preferably the first pitch angle has the same amount as the second Incline. Thus, the winding material can be particularly evenly the cable drum are wound up and unwound. But it is also conceivable that the pitch angles are different, so that the winding material depending on the direction of movement of the guide element on the guide axis different fast, d. H. different densities next to each other lying on the winding drum is wound.

Preferably is the outer circumference the leadership role connected in such a frictional engagement with the winding material, that the guide roller by the winding material entering during the winding in a rotary motion around the guide axis is brought. This makes it particularly simple, robust and inexpensive Way possible, the leadership automatically with the winding and unwinding of the winding material in a rotary motion around the guide axis and thus to put in a reciprocating motion along the guide axis.

advantageously, is the distance of the holddown to the guide axis in the different Adjustable positions. By this adjustment is the hold-down so to speak placed in a first and / or second basic position. Of course you can also moves such an adjustable hold-down between the two basic positions become. By adjusting the distance between downholder and outer peripheral surface of the guide member in the first position, the hold-down on winding material different Be adjusted thickness, so that always jumping out of the winding material can be optimally prevented. Setting the basic position The hold-down is much more complex than the near automatically moving the hold between the different ones Positions. Therefore, the hold-down once at the beginning of its useful life adjusted and adapted to the thickness of the winding material. After that stays the setting over the entire service life of the device according to the invention. In contrast For this purpose, the hold-down is between each winding change and unwinding of the winding material switched between the positions, preferably for winding in the first position and for unwinding in the second position.

In 1 is with the reference numeral 1 a device according to the invention for winding and unwinding strand-like winding material, for example, of cables or hoses shown. This includes a winding drum, also referred to as a cable drum 10 pointing at one on a profile tube 50 rotatably mounted axis of rotation 12 is attached and by means of a crank 14 can be set in rotary motion. Of course, the winding drum 10 electrically, pneumatically, hydraulically or otherwise be set in rotary motion. At the outer ends of the cable drum 10 are sidewalls 11a . 11b arranged, which prevent lateral slipping of the winding material.

At the cable drum 10 opposite end of the profile tube 50 is one with a thread 23 provided guide axis 22 angeord net, on the one about the longitudinal axis of the guide axis 22 rotatable guide roller 20 is appropriate. The leadership 20 has a guide groove on the outer circumference 24 on. There is also a hold-down 40 represented, which is formed as a cover in the form of a cylinder jacket portion. The cover 40 is on a pivot axis 90 to this pivotable on the profile tube 50 attached.

In 1 is the cover 40 shown in their first position in which they the winding material 30 on the outer peripheral surface of the guide roller 20 suppressed. This causes the winding material 30 when winding up the roll 20 in a rotational movement about the guide axis 22 and because of the thread 23 in a reciprocating motion along the guide axis 22 , In 1a is the cover 40 shown in its second position, in which it is given away to the top, so that the distance between the cover 40 and the outer periphery of the guide roller 20 greater than in the first position. More specifically, that is the pivot axis 90 opposite side of the cover 40 at a greater distance to the outer periphery of the guide roller 20 Side of the cover 40 The cover 40 can the second position eg. When unwinding the winding material 30 from the cable drum 10 take, especially if the unwinding of the winding material 30 easy on the already unwound winding 30 pulled and the winding drum 10 is thereby set in a rotary motion.

Strictly speaking, it serves the pivot axis 90 opposite side of the cover 40 as the actual hold-down for the winding material 30 , The remaining part of the cover 40 mainly used to protect the guide axle 22 and the leadership 20 from dirt (eg mortar residues, sawdust, sand, etc.) and moisture (raindrops, splash water, etc.). To roll up the winding material 30 To facilitate, it is conceivable that the entire of the pivot axis 90 opposite side of the cover 40 around a rotation axis 46 (see. 5 ) is rotatable, wherein the axis of rotation 46 preferably parallel to the axis of rotation 90 or to the guide axis 22 and / or the axis of rotation 12 the winding drum 10 runs. For this purpose, for example, one about the axis of rotation 46 rotatable roller 48 in the pivot axis 90 opposite side of the cover 40 to get integrated.

To use the device for winding or unwinding of winding material, the device by means of the holding element 60 held. Alternatively, it is also conceivable to fix the device in a frame provided for this purpose steadfastly.

For example, to wind a cable, the cable becomes 30 in the guide trough 24 the leadership role 20 inserted. The hold down 40 is placed in the first position so he slipping out of the cable 30 from the guide trough 24 effectively prevented.

Now, for example, the cable drum 10 by means of the crank 14 put in a rotary motion that is suitable to the cable 30 to wind up, so by means of the cable 30 and between the cable 30 and the guide trough 24 existing stiction the leading role 20 put in a rotary motion.

at this embodiment It is easy to see that a person with one hand the cable drum can hold while she uses the crank with the other hand. This can, for example an extension cable, which is provided with a plug, which is still in a socket already wound evenly on the way to the socket become. This means a comfort increase and a workload, because it is no longer necessary to go to the socket first, to the Remove plug there and then the cable drum, for example must be kept on the ground, so that with one hand the cable drum can be set in motion while using the other hand the cable is guided.

In the 2 illustrated plan view of a device according to the invention illustrates the emergence of a movement along the longitudinal axis of the guide axis 22 by the above-described rotational movement of the guide roller 20 :
The leadership 20 is shown in a longitudinal section, leaving a runner 70 is visible, which has a female thread section 71 and by means of one with an external thread 84 provided bolt 80 is adjustable. The guide axis 22 has a cross thread 23 that has a right-hand thread 23R and a left-hand thread crossing this 23L having. At the two ends of the guide axle 22 the slopes of the left-hand thread change 23L and the right-hand thread 23R so, the profiles of these threads merge into each other.

The leadership 20 is so on the leadership axis 22 arranged that the female thread section 71 of the runner 70 in a groove of the cross thread 23 to be led. This causes a rotational movement of the guide roller 20 a shift in leadership 20 along the longitudinal axis of the guide axis 22 , If the guide roller reaches one end of the guide axle 22 and followed the runners so far, for example, the right-hand thread 23R , So there causes the change in the pitch angle of the external thread of the guide axis that the rotor 70 around its axis of rotation 86 also by this amount turns until he finally the pitch angle of the left-hand thread 23L has accepted and from the left-hand thread 23L back to the other end of the guide axle 22 to be led.

The hold down 40 is in 2 dashed in its first position to allow a clear view of the underlying components. In the in 2 V-designated areas a snap or snap connection is provided to the cover 40 safe and reliable in the first position. The snap or locking connection is described below with reference to 5a and 5b explained in more detail. The snap or latching connection is preferably designed such that the cover 40 when unwinding the cable 30 simply by pulling on the already unwound cable end up to the second position (see. 1a ) is brought. After unwinding the cover is brought by gentle pressure from above back to the first position and stands for a winding of the cable 30 ready.

In 3 is the in 2 illustrated section through the guide roller 20 shown enlarged. One at the top of the female thread section 71 of the runner 70 lying angle 72 here is about 90 °, which is a particularly good guide of the female thread section 71 in the thread 23 allowed. With the reference number 81 is a spring referred to in cooperation with one on the bolt 80 attached printing surface 82 one by turning the bolt 80 adjustable spring force on the rotor 70 exercises. As a result, a minimum contact pressure of the female threaded portion 71 to the external thread 23 the guide axis 22 guaranteed.

In 4 is a cross section through the guide axis 22 and the leadership 20 shown. An in 4 not shown cable 30 gets in the guide trough 24 guided. An angle 73 of about 100 ° indicates the size of a runner 70 illustrated circle segment. The bolt 80 that for adjustment and as a rotation axis 86 for a rotary movement of the runner 70 around a trained as a depression pivot 85 serves, is of the spring 81 surround.

In 5a is the distal end of the profile tube 50 shown. The cover 40 is shown in her first position. In the bottom of the profile tube 50 is a hole 92 introduced, in which a ball 94 is held spring loaded. The spring is denoted by the reference numeral 96 designated. The diameter of the opening of the hole 92 is after inserting the ball 94 at least partially so reduced that the ball 94 in the hole 92 is held. By pressure on the ball 94 from outside (in the embodiment from below) becomes the ball 94 against the spring force in the hole 92 pressed.

The cover 40 has an extension 42 on which down and laterally to below the distal end of the profile tube 50 is guided. In the horizontal area of the extension 42 is one in the direction of the profile tube 50 directed depression 44 educated. The depression 44 is positioned so that it is exactly opposite the ball 94 located when the cover 40 in the first position.

If the cover 40 is brought into the first position, the ball is 94 first through the horizontal part of the extension 42 into the hole 92 pressed. Once the cover 40 has reached the first position becomes the ball 94 through the spring 96 pressed outwards again and is partially from the depression 44 added. The ball 94 and the depression 44 are in terms of shape and / or surface texture such that the cover 40 safely held in the first position.

In the embodiment of 5b is the hole 92 on the front side of the distal end of the profile tube 50 educated. Accordingly, the extension points 42 only a vertical part on and is the recess 44 in the direction of the profile tube in the vertical part of the extension 42 educated. Again, the recess 44 positioned so that they are exactly opposite the ball 94 located when the cover 40 in the first position.

Furthermore it is suggested that on the cover 40 a cable cleaner 100 is arranged, which is the winding material 30 at least when winding (ie when the cover 40 located in the first position) at least partially surrounds. The cable cleaner 100 is at the cover 40 guided in such a way that it the to and fro movement of the guidance role 20 on the guide axis 22 follows. It is suggested that at the bottom of the cover 40 a guide rail 102 is arranged, on which the cable cleaner 100 is guided back and forth. The cable cleaner 100 will be together with the cover 40 pivoted upward to the second position. In this case, the winding material occurs 30 preferably from the cleaning area of the cable cleaner 100 out, leaving the winding material 30 then free from the winding drum 10 can be handled.

As a possible concrete embodiment, a cable cleaner 100 proposed, the an annular support or support structure (eg. In the form of a wire loop) 104 having, which with cleaning agents (eg. In the form of cleaning bristles) 106 is busy. The support or support structure 104 has a passage opening 108 on, through which the winding material 30 into the inner of the ring or the loop can enter and exit. In 6 you can clearly see that the cable 30 almost over its entire circumference of the cleaning bristles 106 of the cable cleaner 100 is surrounded. In the passage opening 108 are also bristles 106 arranged to prevent unintentional slipping out of the cable 30 to prevent.

The float of the cable cleaner 100 can mechanically attach to the leadership role 20 be coupled. In addition has the cable cleaner 100 about mechanical gripping elements, which is the leading role 20 embrace on both sides. In this way will be a movement of leadership 20 over the gripping elements on the cable cleaner 100 transfer. Alternatively, it is also conceivable that the reciprocating motion of the cable cleaner 100 is effected solely by the cable guided therein. The cable 30 when rolling up by the leadership role 20 put in a float. This can be done with appropriate storage of the cable cleaner 100 in the guide rail 102 a reciprocating of the cable cleaner 100 with the cable 30 cause.
