Resumen
PROBLEM TO BE SOLVED: To provide an inexpensive aerial system that can form bypasses and entrances on both sides of a main circulating path without needing a travel rail for a truck on the main circulating path. SOLUTION: A aerial system for light product transportation, storage, classification and control is formed of a closed main circulating path 2 along which trucks with product units hanging travel, and various stations 1, 3, 4, 5 are provided on both sides of the main circulating path 2. The aerial system is provided with a means for identifying the identification codes of trucks, and control cards for the state of the trucks and the main circulating path 2. The main circulating path 2 is provided with a series of identical strip pieces 15 pivotally fixed to a main support body 16, and the main support body 16 has a clearance 19 and a clamp for supporting the truck with light products hanging. The truck has a cylindrical top part so as to support the main support body 16 on a wheel clamp. The truck enters from the lowest spot of the stations 1, 3, 4, 5 and is pulled up to the main circulating path 2 by hoisting mechanism having a detector for detecting the presence of the truck at the lowest spot.
Reivindicaciones
1. Aerial system for automatic transport, storage, classification and control of hanging light products, including a transport system formed by a main closed circuit (2) with diverse stations (1, 3, 4, 5) on each side of same, along which carriages (8) travel, from which the production units are hung, including the means to identify the carriages, control cards for the stations and the main circuit and the means of communication between the cards, a control computer and the operators, with the appropriate computer resources to know the position and status of the carriages at all times and to control their movement according to flexible preset routes, characterised because its main circuit includes a series of identical flanges (15) articulated through primary supports (16) that have a gap (19) and a trigger (37) to hold the carriages, so these are transported hanging along said circuit, a series of detours that include a cam (35) that acts on the trigger releasing the relevant carriage that drops due to its own weight on a fixed (37) or mobile (38) stretch, with a detour to the relevant station, on the rails of which, the carriages move supported on wheels (10). 2. Aerial system according to claim 1, characterised because the carriages have a cylindrical shape (9) at the top so they may be held handing from the primary supports using triggers, for wheels (10) in the central part to rest and move on the rails of the stations, with U shaped lateral flanges (23) that allow the identification codes (12) to be held by an arm (28), to be identified by appropriate readers, of a rigid element (36) to transmit the load hung toward the wheels, or toward the cylindrical shape or the flanges. 3. Aerial system according to claim 1, characterised because the carriages may enter from the lowest point (24) of the stations up to the main circuit due to a hoist mechanism that includes a carriage presence detector (25) at the lowest point, a hoist arm (28) shaped to pick the carriage up by the flanges (23) and articulated on a small hoist carriage (27) that may be moved guided by a hoist tube (26), the upper end of which is at the level of the main circuit, a flexible cable (32) that is rigid to traction and runs over a pulley, connecting the hoist carriage to a drive carriage (29) that may be moved guided along a lengthwise guide (30) included in the main circuit, that drive carriage having a mobile part (31) between two positions activated by an activator so the activation position of the mobile piece interferes with a primary support that moves to drag the drive carriage to the end of the lengthwise guide where a camp moves the mobile part to the position of non interference with the primary supports, allowing the drive carriage to return to its initial position due to the weight of the hoist carriage, a presence detector (40) for the drive carriage at its original position and a detector (33) for carriage free primary supports, linking the lengths and positions of the hoist tube, of the lengthwise guide and the flexible cable to make the initial positions of the hoist carriage and the drive carriage and the final positions coincide so the cylindrical shape of carriage coincides with the gap on the primary supports.
