Abstract
Abstract A device is provided for conveying reinforcing or skeleton elements to a welding station and for holding and aligning said elements in relation to a metal sheet at the welding station, said device comprising a traveling carriage having a box or beam construction movably and pivotally mounted thereon, electromagnets being attached to said box or beam construction for holding said reinforcing elements. The electromagnets are arranged in a lower and an upper row, the electromagnets in the lower row being fixed and the electromagnets in the upper row being displaceable, thus enabling the device to handle reinforcing elements of varying sizes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
A device for conveying reinforcing elements to a welding station and for holding and aligning these in relation to a sheet of metal at the welding station to which reinforcing elements are to be welded substantially perpendicularly, characterized by a traveling carriage (1) on which reinforcing elements (3) are conveyed and which is provided with a rigid box or beam construction (7) carrying a pluraLity of electromagnets (5, 6) which hold said reinforcing elements and which are arranged in a lower and an upper row, the electromagnets in the lower row (5) being fixed so that they are close to said sheet of metal (4) in the welding station and the electromagnets in the upper row (6) being displaceable in a direction substantially perpendicular to the surface of said sheet of metal, and the box or beam construction (7) being movable in the traveling carriage (1) so that it can be raised or lowered in relation to said sheet of metal for applying the reinforcing element (3) thereon and so that it can be pivoted for turning the held reinforcing element away from a position perpendicular to said sheet of metal if desired.
Claim 2
Independent Claim
193 words
A device for conveying reinforcing elements to a welding station and for holding and aligning these in relation to a sheet of metal at the welding station to which reinforcing elements are to be welded substantially perpendicularly, characterized by a traveling carriage (1) on which reinforcing elements (3) are conveyed and which is provided with a rigid box or beam construction (7) carrying a pluraLity of electromagnets (5, 6) which hold said reinforcing elements and which are arranged in a lower and an upper row, the electromagnets in the lower row (5) being fixed so that they are close to said sheet of metal (4) in the welding station and the electromagnets in the upper row (6) being displaceable in a direction substantially perpendicular to the surface of said sheet of metal, and the box or beam construction (7) being movable in the traveling carriage (1) so that it can be raised or lowered in relation to said sheet of metal for applying the reinforcing element (3) thereon and so that it can be pivoted for turning the held reinforcing element away from a position perpendicular to said sheet of metal if desired.
Claim 3
Dependent Claim
74 words
A device according to claim 1, characterized in that the box or beam construction (7) is arranged to be pivoted about an axis through the line of contact (16) between the reinforcing element and said sheet of metal (4) by means of brackets (13), said brackets being attached to the construction and having slots (14) therein, said slots constituting parts of a circle arc and cooperating with journal pins (15) attached to the carriage.
Claim 4
Dependent Claim
49 words
A device according to claim 2 characterized in that said journal pins (15) are attached to members (17) which can be raised and lowered in the carriage, said members also carrying activating members (20, 21, 22, 23, 24, 25) to displace said brackets (13) relative to the journal pins.
Claim 5
Dependent Claim
30 words
A device according to claim 1 characterized in that the surfaces (26, 27) of the electromagnets cooperating with the reinforcing element (3) are flat and lie in the same plane.
Claim 6
Dependent Claim
54 words
A device according to claim 1 characterized in that the electromagnets (6) in the upper row are displaced in the longitudinal direction of the box or beam construction (7) relative to the electromagnets (5) in the lower row, so that the former can be lowered between the latter to the same level as these.
