Definitions
- the present invention relates to an expandable mandrel spool for a spool provided with at least one mandrel mounted on a frame, the mandrel having movable jaws between a loading position in which the jaws are retracted and a position of use in which the jaws are expanded and maintain the coil in a substantially horizontal axis.
- the reels are stored and transported in a standing position, their axis being horizontal, or in a supine position, their axis being vertical. In the upright position, they can be gripped by the forks of a forklift to be loaded directly onto the horizontal-axis mandrels. In the supine position, they are raised flat by the forks of a forklift and must be tilted a quarter of a turn before being loaded on the mandrels.
- This reversal operation is dangerous and carried out most of the time either by suspending the hook of a traveling crane, or directly by the forklift.
- rockers To perform this reversal operation safely, there are special machines called rockers. But their use generates additional operations in the handling of the coils. In addition, they represent a significant investment, are bulky and require external energy input.

- the chuck To use the spool, the chuck must be tilted a quarter turn and the spool must be locked in position. This system is unsatisfactory since it requires an actuator for chuck tilting and locking mechanical position in the coil since the clamping of the jaws on the inner diameter of the coil is not ensured when the axis of the mandrel is horizontal.
- the present invention aims at proposing a new solution which eliminates the disadvantages of both the crank system and the jack system for the expansion and retraction of the jaws of the chuck, which is economical, simple, maintenance-free, or the contribution of energy and guarantees an optimal and reproducible clamping of the jaws on the inside diameter of the coil in the position of use.
- the invention proposes alternatively an integrated solution for tilting the coils when loaded in the prone position, while ensuring their tightening in the use position.
- the invention relates to a mandrel of the type indicated in the preamble, characterized in that it comprises means arranged to generate the automatic expansion of the jaws under the weight of the coil and the clamping of the jaws on the inner diameter of the coil, the clamping force of the jaws may be proportional to the weight of the coil, placing the mandrel in the use position.
- the reel advantageously comprises a return device coupled to said means and arranged to generate the automatic retraction of the jaws in the absence of a reel and the return of the chuck to the loading position, as well as a locking mechanism for locking the mandrel in position use.
- the reel comprises an expansion device connected to the jaws of the mandrel and said means comprise a device for guiding the mandrel between at least one loading position and a position of use, the guiding device being coupled to the device of the mandrel. expansion in order to drive the expansion automatic jaws simultaneously displacement of the mandrel under the weight of the coil.
- the expansion device comprises a tie rod connected to the jaws by a variable geometry mechanism, this tie rod being slidable in the axis of the mandrel for moving the jaws between their loading and unloading positions.
- the tie is preferably connected to the frame by a mechanical connection selected from the group comprising an articulated link, a rack-and-pinion system, a jack, a slide, a combination of these mechanisms.
- the loading and unloading positions of the mandrel are parallel and the guide device is arranged to move the mandrel in a substantially rectilinear path.
- the guide device may comprise a rocker coupled to the frame by a fixed pivot axis and the mandrel by its axis of rotation, the two axes being parallel. It may also comprise a carriage coupled to the mandrel by its axis of rotation and slidably mounted in the frame along an axis perpendicular to said axis of rotation of the mandrel.
- the loading and unloading positions of the mandrel are perpendicular and the guide device is arranged to move the mandrel in a substantially circular path.
- the guide device comprises a rocker coupled to the frame by a fixed pivot axis and the mandrel by its axis of rotation, the two axes being perpendicular and offset.
