Definitions
- Unwinding mandrel for connection to an unwinding device for unwinding elongated materials
- the invention relates to an unwinding mandrel for connection to an unwinding device for unwinding elongated materials such as cables or pipes from a collar, the unwinding mandrel having a main body for arrangement in the center of the collar and a connecting section for releasably connecting the unwinding mandrel to the unwinding device.
- Elongated materials such as cables, tapes or pipes are often available in rolls for storage or transport, i.e. rolled up as a bundle.
- a core for example a cable drum or a coil, can be used, or the material can be without a core.
- an unwinding mandrel is arranged centrally in the collar and prevents the collar from slipping on the device.
- an unwinding mandrel is understood to be an elongate component that rotates with the collar or the spool when the material is unrolled or rolled up.
- the unwinding device is arranged at a suitable distance from the central opening of the standing federal government and this is then tilted over and onto the unwinding device.
- the unwinding mandrel is thus at least partially inserted into the central opening. This way the bunch won't roll away while it's being unrolled.
- this is difficult and time-consuming, since the distance must be measured precisely in order to hit the unwinding mandrel precisely with the central opening.
- the object of the invention is to avoid the problems described and to provide an unwinding mandrel which enables accelerated unwinding or rolling up.
- the rolling mandrel has at least one, preferably four, movable bodies which are pivotably connected to the main body via at least one joint transversely to a main axis of extension of the main body.
- releasable connection is meant an operationally nondestructive releasable connection.
- the bodies can be brought into contact during transport, which means that the unwinding mandrel can be transported as easily as possible. If they are swiveled out of the resting position, they can serve to accommodate the federal government and thus enable improved rolling and unrolling, as they can better stabilize the federal government.
- the body can serve as a connection between the unwinding mandrel and the federal government, in particular the special coil of the federal government and better fix the unwinding device with the federal government.
- This is particularly advantageous in the case of bundles with a core, such as, for example, the cable drum.
- This enables the unwinding mandrel to be inserted and fixed in the upright collar (ie cable drum) and this connection with the cores is strengthened in a form-fitting and / or frictional manner.
- the collar together with the unwinding mandrel and the unwinding device attached to it can be tilted so that the unwinding device is arranged between the collar and the substrate. Complicated measuring and positioning of the unwinding device is no longer necessary.
- the body preferably forms a support surface for supporting the collar in order to support the collar.
- the support surface is therefore essentially horizontal in the position of use.
- essentially horizontal means that the deviation from the horizontal plane is so small that the collar can rest on it without slipping.
- the bodies can be brought into a resting position in which they run essentially along the main extension axis of the main body. This enables a particularly compact form of transport. Furthermore, it can be provided that the bodies in the abutment position at least partially rest against the main body, preferably at least at their end opposite the joint. The joint can be arranged in the area of the connecting section. This enables the body to unfold in the direction of the unwinding device.
- At least one body is preloaded in at least one position and preferably at least one spring exerts a force on the body in at least one direction. In this way, the position of the body can be better defined and unintentional movement of the same can be prevented.
- the body is biased away from its abutment position in the direction of a receiving position, wherein in receiving position the opposite ends of the bracket from the main body are removed from the main body than in the abutment position.
- This allows the body to be self-clamping. In this way, the body can connect to the reel even when it is inserted into the reel and fix the unwinding mandrel in the reel.
- the body is biased from a transition point along its movement between the resting position and receiving position in the direction of the receiving position and that the body is preferably biased into the resting position before the transition point.
- the body is thus held in its transport position and is not unintentionally unfolded during handling. If the body is moved up to the transition point, this automatically changes to the receiving position. This facilitates and improves the positioning of the body.
- the body can be brought into a receiving position in which it runs essentially transversely to the main axis of extension.
- the movable body is designed as a bracket.
- bracket is meant a shaped piece with a substantially constant profile, which has at least two bracket parts that connect the joint to the end of the body opposite the joint.
- the bracket is preferably made of a metal such as steel or aluminum and particularly preferably has a constant profile.
- the collar can better connect to the body, it is preferably provided that at least one body has a termination at its end opposite the joint, which, when in contact, points in the direction of the main extension axis.
- the closure prevents part of the covenant from sliding over the body.
- the termination can be formed by a part formed from the body. This can be produced particularly easily and therefore inexpensively, especially if the body is designed as a bracket.
- the termination has a molded part applied to the end of the body.
- This molded part can be, for example, a non-slip plastic or rubber cover.
- the body is designed to be telescopic, preferably along its main extent. This allows the length of the body to be adjusted depending on the size of the waistband.
- At least one body has a closure at its end opposite the joint, and that the closure is designed telescopically, preferably in a resting position in the direction of the main extension axis.
- the body can have a support surface for supporting the federal government, which preferably points in the abutment position to the main body.
- At least two bodies can be provided and the bodies have at least partially different lengths.
- At least the main body is at least partially made of plastic. This makes it possible to achieve a low weight and a robust structure.
- the main body is preferably designed to be telescopic, particularly preferably along the main axis of extension.
- a telescopic body of the main body can have a locking mechanism for fixing at least one position on the main body and the locking mechanism can preferably be locked by a snap lock after it has been pulled out of the main body.
- the connecting section can have a snap connector for a form-fitting connection with the unwinding device and the connection can be released by means of a push button on the unwinding mandrel.
- a snap connector or a snap lock is an element for the positive locking of components to one another, in that parts to be joined are hooked to one another when a certain position is reached and can be brought out of this position by pressing on a part against a bias.
- the invention also comprises an unwinding system with an unwinding device for unrolling elongated materials such as cables or pipes from a bundle, with a base plate for standing on a surface.
- the unwinding system has at least one unwinding mandrel of the type described above.
- the unwinding mandrel is preferably mounted so as to be rotatable relative to the base plate.
- a rotary plate rotatable about an axis of rotation for receiving the federal elongate union material is mounted on the plate to the bottom.
- the unwinding device can optionally be used without the unwinding mandrel of the type described above, for example by placing a coil on the turntable, or a loose collar is placed on the movable body of the unwinding mandrel attached to the turntable.
- the roll-off device has a connector for non-destructively releasable connection to the connecting section of the roll-off mandrel.
- the turntable can be rotatably connected to the base plate centrally, preferably along the axis of rotation.
- the turntable can be rotatably connected to the Bo denplatte via preferably horizontally arranged bearings.
- the base plate can have a receptacle for various additional devices, preferably length measuring devices for the elongated material.
- the body can at least partially extend in the receiving position on the rotary disc addition.
- the unwinding mandrel it is possible for the unwinding mandrel to be attached to the base plate without a turntable.
- only one pivot bearing is provided to ensure that the unwinding mandrel can rotate.
- Such a design can in particular be designed as an extension of a roll-off device, which has a turntable with a roll-off mandrel that can be fastened thereon and one or more rotary bearings for receiving further roll-off mandrels. It is then possible to unroll several wires, each of which is present on a bundle, at the same time.

- FIG. 5 shows a roll-off system according to the invention in a second embodiment in a receiving position in a view from the side;
- Fig. 6 is an exploded view of a roll-off device of the second embodiment.
- Figs. 1 to 4 show a first embodiment of an unwinding mandrel 1b which has an elongated, essentially round main body 1c which extends along a main extension axis 2.
- a connection section 11 is arranged, which has a connection surface standing normal to the main extension axis 2 and a receiving opening for connecting to an unwinding device lb and receiving a pivot pin 3 of the unrolling device lb.
- the pivot pin 3 also acts as a connector. If the pivot pin 3 is inserted, a positive connection is established by a snap connection, which can be released by pressing the push button 8 against a preload of an elastic spring element.
- a total of 4 bodies 18 are each connected via a joint, which are designed as a one-piece bracket. All brackets are made the same and are arranged radially symmetrically about the main axis 2 extension.
- the joints allow pivoting about axes normal to the main axis of extension 2.
- the respective opposite pivot axes of the joints are parallel.
- Each body 18 is bent into shape from a piece of steel rod and has a substantially constant, round profile. At the end opposite the joint, each body 18 has a termination 15 which is triangular in shape and is normal to its main extent.
- the main body 1c is made of plastic and has a telescopic body 7 which is inserted in the end opposite the joint. This is in a folded position as shown in Figs. 1 or 2, it can be brought into an unfolded position by pulling it out (as shown in FIGS. 3 and 4), in which a snap lock 9 fixes the position of the telescopic body 7 in relation to the rest of the main body 1c. As with the snap connection, this can be released by another push button.
- the bodies 18 are shown in Figs. 1 and 2 shown in a lay-up position. The bodies 18 lie parallel to the main axis of extension 2 and on the main body 1c.
- the terminations 15 move away from the main extension axis 2.
- the pivoting of the body 18 is preferably limited to a maximum angle starting from the abutment position, particularly preferably a maximum of 180 ° and very particularly preferably 90 °.
- the bodies 18 are normal times to the main axis of extension 2 and thus form receiving surfaces on which a collar can be received.
- the terminations 15 point upwards and can prevent slipping off the edge areas of the federal government.
- an unwinding device la is shown on which an inventive unwinding mandrel lb is connected ready for operation.
- the body 18 protrudes beyond a turntable 1 of the roll-off device la.
- the bodies 18 lie on the turntable 1.
- the main axis of extension 1c is coaxial with the pivot pin 3 and the axis of rotation 3a, which connects the turntable 1 to a base plate 4.
- the turntable 1 and the base plate 4 can also be designed differently, for example not as continuous plates but only as strips or rod elements.
- Turntable 1 and base plate 4 can be rotated against each other via the axis of rotation 3a and are also supported by bearings in the form of plastic rollers.
- the base plate 4 has a receptacle 6 on which, for example, a length measuring device for measuring the length of the unrolled material can be carried out.
