Abstract:
A system (1) for transferring a movable load (2) for an installation (3) for conveying a load (2), making it possible to transfer a load (2) from a so-called arrival track (8), supported by a fixed frame (40) of the installation, where the load (2) is conveyed along a so-called entry conveying path (C), to at least first (9) and second (10) so-called exit tracks where the load (2) is conveyed respectively along first and second so-called exit conveying paths (C1, C2) having respectively first and second so-called exit radii of curvature (R1, R2), or from at least first and second tracks (9, 10) to a single track (8), the system (1) comprising a movable track section (11) adjustable for position, where the load (2) is conveyed along the so-called intermediate conveying path, the said section (11) comprising a fixed end (12) disposed opposite one end (13) of the arrival track (8), and a movable end (14), able to be moved by an actuating device (15) in order to be disposed opposite one end of each exit track (9, 10), characterised in that(a) the section (11) comprises at least two track segments (16) associated end to end, mounted at least pivotally with respect to each other by means of association means (17), disposed close to a junction (18) between the segments (16) so that the entry, intermediate and exit conveying paths form end to end a conveying path whose tangent has a continuous variation, and(b) an adjustment device (24) for adjusting the magnitude of the relative movement of the adjacent segments (16) which comprises at least a first pair (25) of pieces (26, 27) forming stops, disposed on each side of the junction (18) between the two track segments (16), a first piece (26) of the first pair (25) being fixed to one of the two track segments (16) on one side of the section (11), a second piece (27) in the first pair (25) being fixed to the other track segment (16) on the same side of the section (11) as the first piece (26), opposite the latter with an adjusted separation, the pieces (26, 27) forming a corresponding stop being able to come into contact with each other when the movable end (14) is opposite the end of the first exit track (9), and the separation between the said pieces (26, 27, 30, 31) forming the stops is adjustable by means of an adjustment device (33) comprising an adjustable finger (34) mounted on one of the pieces forming the stops in the same pair (25, 29).
