Abstract

A device for deposition of fibers on a support ( 30 ) for producing a panel with an axis of revolution, includes a deposition head ( 32 ) and elements for positioning the deposition head relative to the support ( 30 ), with the positioning elements of the deposition head having kinematics including a first translation in a first direction (X) that is parallel to the axis of revolution, a second translation in a second direction (W) making it possible to come more or less close to the head of the support, a first rotation (C) around a first rotary axis combined with the second direction (W), and a second rotation (B) around a second rotary axis that is perpendicular to the first and second directions, wherein the kinematics of the positioning elements of the head include a third rotation (A) around a third axis of rotation that is parallel to the first direction (X).

First claim

The invention claimed is:

1. A device for deposition of fibers on a support for producing a panel with an axis of revolution, said device comprising:
a deposition head; and
means for positioning said deposition head relative to the support, the means for positioning having kinematics comprising
a first translation in a first direction that is parallel to the axis of revolution,
a second translation in a second direction making possible to bring the deposition head close to the support,
a first rotation around a first rotary axis combined with the second direction,
a second rotation around a second rotary axis that is perpendicular to the first and second directions, and
a third rotation around a third axis of rotation that is parallel to the first direction, the third axis of rotation being combined with the axis of revolution of the panel to be produced, and the third rotation is placed between the two translations,
wherein
the means for positioning is configured to be split on both sides of the third axis of rotation makes possible to limit the weight of parts in movement around said third axis of rotation and makes possible to increase the range of the angular section of the cross-sections of panel, and it is not necessary to combine the third axis of rotation with the axis of revolution of the panel, since the control of the position of the center of the roller is done in cylindrical coordinates, and
the device further comprises:
a crosspiece that moves translationally in the first direction,
a telescopic upright,
a joint that connects one end of the telescopic upright to the deposition head comprising the first and second rotations, and

a shaft that corresponds to the third axis of rotation of the third rotation and whose ends are connected to two forks that are integral with the crosspiece, whereby the telescopic upright is able to pivot around said shaft.

2. The device for deposition of fibers according to claim 1 , further comprising a frame on which the support and rails are connected parallel to the first direction and along which the crosspiece moves translationally, with the support, the rails, the crosspiece, and the shaft being arranged in such a way that the axis of revolution of the support is combined with the shaft.

3. A device for deposition of fibers on a support for producing a panel with an axis of revolution, said device comprising:
a deposition head; and
means for positioning said deposition head relative to the support, the means for positioning having kinematics comprising
a first translation in a first direction that is parallel to the axis of revolution,
a second translation in a second direction making possible to bring the deposition head close to the support,
a first rotation around a first rotary axis combined with the second direction,
a second rotation around a second rotary axis that is perpendicular to the first and second directions, and
a third rotation around a third axis of rotation that is parallel to the first direction, the third axis of rotation being combined with the axis of revolution of the panel to be produced, and the third rotation is placed between the two translations,

said device further comprises a crosspiece that moves translationally in the first direction, a telescopic upright, and a joint that connects one end of the telescopic upright to the deposition head that comprises the first and second rotations, and a shaft that corresponds to the axis of rotation of the third rotation and whose ends are mounted to pivot relative to forks that are integral with the crosspiece, with the telescopic upright being stationary relative to the shaft.

4. The device for deposition of fibers according to claim 3 , further comprising a frame on which the support and rails are connected parallel to the first direction and along which the crosspiece moves translationally, with the support, the rails, the crosspiece, and the shaft being arranged in such a way that the axis of revolution of the support is combined with the shaft.

5. A device for deposition of fibers on a support for producing a panel with an axis of revolution and an angular sector forming an angle of an order of 240°, said device comprising:
a deposition head; and
a positioning device adapted for positioning said deposition head relative to the support, the positioning device configured to perform
a first translation in a first direction that is parallel to the axis of revolution,
a second translation in a second direction making possible to bring the deposition head close to the support,
a first rotation around a first rotary axis combined with the second direction,

a third rotation around a third axis of rotation that is parallel to the first direction, the third axis of rotation being combined with the axis of revolution of the panel to be produced, and the third rotation is placed between the two translations, wherein
splitting the positioning means on both sides of the third axis of rotation makes possible to limit the weight of parts in movement around said third axis of rotation and makes possible to increase the range of the angular section of the cross-sections of panel, and there is no need to combine the third axis of rotation with the axis of revolution of the panel, since the control of the position of the center of the roller is done in cylindrical coordinates, and wherein
said device further comprises a crosspiece that moves translationally in the first direction, a telescopic upright, a joint that connects one end of the telescopic upright to the deposition head comprising the first and second rotations, and a shaft that corresponds to the axis of rotation of the third rotation and whose ends are connected to two forks that are integral with the crosspiece, whereby the telescopic upright is able to pivot around said shaft.

6. A device for deposition of fibers on a support for producing a panel with an axis of revolution and an angular sector forming an angle of an order of 240°, said device comprising:
a deposition head; and
