Width-adjusting device for conveyor corridor(s)
First Claim
1. A width-adjusting device for conveyor corridor(s), comprising a mechanism with high gear reduction integrally attached to a chassis of said conveyor, said mechanism being arranged between a control shaft and a wall or walls of said corridor and comprising:
- a final drive offering irreversible operation, comprising;
—
said control shaft in the form of a first endless screw, and—
a toothed wheel,a maneuvering system for maneuvering at least one of the walls of said corridor, comprising a second endless screw and a nut, said second endless screw being mobile or fixed relative to said toothed wheel.

Abstract
The invention relates to a width-adjusting device for conveyor corridor(s), comprising a wide gear-reduction mechanism connected to the frame (5) of said conveyor, wherein said mechanism is arranged between the control shaft (12) and the wall(s) of said corridor. The device includes: a final drive capable of reverse operation and consisting of said control shaft (12) in the form of an endless screw and of a toothed wheel (11); and a system for controlling at least one of the walls of said corridor, consisting of an endless screw (13) and a nut, the endless screw being mobile or fixed relative to said toothed wheel (11). The shaft (12) of the final drive is a flexible shaft having a long length and engaging with the tension-retaining system (20) for absorbing the pulling and pushing forces in the rotation direction thereof.

10. A method for assembling a width-adjusting device for corridor(s), comprising
a mechanism with high gear reduction integrally attached to a chassis of said conveyor, said mechanism being arranged between a control shaft and a wall or walls of said corridor and comprising: -
a final drive offering irreversible operation, comprising;
—
said control shaft in the form of a first endless screw, and—
a toothed wheel,a maneuvering system for maneuvering at least one of the walls of said corridor, comprising a second endless screw and a nut, said second endless screw being mobile or fixed relative to said toothed wheel, said final drive comprising a flexible control shaft and said toothed wheel engages in a gearbox and, between two consecutive gearboxes, said flexible control shaft is housed in a guiding protective cover, said cover having ends fitted into and/or attached to said corresponding gearboxes, said gearbox comprising; two half-shells machined and intended to be attached to said chassis of the conveyor, a substantially cylindrical housing delimited by said half-shells when they are assembled, said housing being occupied by said toothed wheel, a passage calibrated for said flexible control shaft and arranged in each of said half-shells, said calibrated passage being positioned orthogonally to an axis of said housing and tangential to said housing to allow the operation of said final drive and,—
said half-shells comprise cylindrical projections to guide and cover the threading of said second endless screw for maneuvering said wall(s), of the corridor(s) onto a single row or multi-row conveyor, said method comprising;attaching one of said half-shells of each gearbox onto said chassis of said conveyor, sizing said covers which extend between two gearboxes and slipping them onto the corresponding portion of said flexible control shaft, placing in one of said half-shells said final drive comprising said flexible control shaft and said toothed wheel with said corresponding covers, closing each gearbox by attaching the other half-shell to said half-shell already in place, and connecting said flexible control shaft to a motor. - View Dependent Claims (11)

12. A tension module associated with a flexible shaft which is long and is in the form of an endless screw, said flexible shaft being driven at one of its ends by a motor means in order to maneuver toothed wheels which actuate means for adjusting one or more of walls of conveyor corridor(s), said tension module being arranged at said free end of said flexible shaft and comprising a tensioning system comprising a thrust bearing placed between a ferrule integrally attached to said free end of said flexible shaft and a shoulder, said shoulder being on a tube centered around said flexible shaft and being mobile relative to a chassis of said conveyor while being held in position by a pre-tensioned spring, in a manner that provides a compression displacement and an elongation displacement when there are no forces exerted on said flexible shaft.
