Abstract

The present invention relates to a machine used to assemble metal cages for reinforced concrete piles or similar items, which comprises a control system used to actuate the welding torch (8) and at least a vision device (9) to detect images in the welding areas, the said control system being designed to receive the images of the welding areas and switch on the welding torch (8) when necessary.

Claims

AMENDED CLAIMS received by the International Bureau on 04 feb 2009 (04. 02. 2009)
1. Machine used to assemble metal cages for reinforced concrete piles or similar items, the said cages being composed of at least multiple cross pieces (3) around which a spiral reinforcement rod (4) is wound, the said machine comprising at least: two housing heads (5) for the cross pieces (3), a deposition device (6) of at least one spiral rod (4), a welding torch (8) to weld the cross pieces (3) and the spiral rod (4), machine characterised in that it also comprises a control system of the welding torch (8) and at least a vision device (9) situated in the welding torch (8) to detect images of the welding area, designed to detect the passage of each crossing point (11) between a cross piece (3) and the spiral rod (4) in the welding area, the said control system being designed to receive the images of the welding area transmitted by the vision system (9) and actuate the switch on of the welding torch in the crossing point (11).
2. Machine as claimed in the above claim characterised in that the housing heads (5) are situated one in front of the other one, with possibility to rotate around their axis and slide on tracks (7).
3. Machine as claimed in claim 1 or 2, characterised in that the vision system (9) and/or the welding torch (8) are fixed to a support (10) fitted to the frame of the device (1) or onto the ground.
4. Machine as claimed in one or more of the above claims, characterised in that the welding torch and/or the vision device (9) are mobile with respect to the support means (10) associated with them, by means of adjustment means (12, 13) that allow for fine adjustment of the position of the welding torch and the vision device (9).
5. Machine as claimed in one or more of the above claims, characterised in that the adjustment means (12, 13) allow for moving the welding torch (8) and the vision system (9) preferably according to two axes: a horizontal axis, that is basically parallel to the longitudinal axis of the cross pieces (3) and a vertical axis perpendicular to the horizontal axis.
6. Machine as claimed in one or more of the above claims, characterised 14
in that the adjustment can be controlled manually or automatically with the adjustment means (12, 13) by the control system.
7. Machine as claimed in one or more of the above claims, characterised in that the vision device (9) is a video camera or similar item.
8. Machine as claimed in one or more of the above claims, characterised in that the control system also comprises at least one monitor to display images and at least means to enter data or controls by the operator, the said control system being automatic or controlled by the operator.
9. Machine as claimed in one or more of the above claims characterised in that the control system is provided with a memory to store the position and quality of each welding operation.
10. Machine as claimed in one or more of the above claims, characterised in that it is provided with a motor to translate and rotate the heads.
11. Machine as claimed in one or more of the above claims, characterised in that it comprises a third adjustment means (14) to move the torch (8) in a radial direction perpendicular to the longitudinal axis of the rods (3), the said adjustment means (14) comprising: a feeler roller (14b) applied at the end of a floating shelf (14d) pivoted at the base of a bracket (14a) connected to the adjustment means (13); - a linear actuator (14c) designed to bring the roller (14b) in contact with the rod (4); a bracket (8b) that supports the torch (8) and is fixed to the floating shelf (14d).
12. Method to assemble a metal cage (2) for reinforced concrete piles or similar items, comprising the following steps:
- winding a spiral rod (4) around multiple cross pieces (3), and
- welding the cross pieces (3) and the spiral rod (4), by means of a welding torch (8), characterised in that it further comprises the steps of - detecting the passage of each crossing point (11) between a cross piece (3) and the spiral rod (4) in the welding area, and
- actuating the switch on of the welding torch (8) in said crossing point 15
(11).
13. Method according to claim 12, characterised in that the step of detecting the passage of each crossing point (11) between a cross piece (3) and the spiral rod (4) in the welding area is performed by means of a vision device (9) which transmits the images of the welding area to a control system of the welding torch (8) to actuate the switch on of the welding torch (8).
