Method and device for depositing a metal coil

A method of depositing a metal strip wound into a coil on first and second support points of a coil buggy,

• characterized by the following steps:
• checking if a following condition is met:
• a diameter of the metal coil is smaller than a threshold diameter, and thickness of the metal strip is greater than a threshold thickness, and strength of the material of the metal strip is greater than a threshold strength;
• and
• manipulating determination that the metal coil would rest on both support points positioned relative to each other in an initial position, in an unstable equilibrium position when the condition is met;
• changing horizontal and/or vertical distance of both support points relative to each other in comparison with an initial position thereof so that the metal coil can be deposited on both support points in a stable equilibrium position;
• and
• depositing the metal coil on both support points having a changed relative position with respect to each other unless this has not been carried out before.

A device with first and second support points for deposition of a metal coil on both support points,

• characterized in that
• at least a first support point is arranged on the device with a possibility of changing a position thereof relative to a second support point;
• a checking device is provided for checking and determining whether the metal coil rests or would rest on both support points in a stable equilibrium position;
• and
• a control device is provided for changing the relative position of both support points to each other, when an unstable equilibrium position is determined, so that the metal coil rests on both support points at least approximately in a stable equilibrium position.

A coil buggy with first and second support points for disposition of a metal coil on both support points so that ends of a metal strip are held by the weight of the metal coil,

• characterized in that
• at least a first support point is arranged on the coil buggy with a possibility of changing a position thereof relative to a second support point;
• a checking device is provided for checking whether a following condition is met;
• the diameter of the metal coil is smaller than a threshold diameter, and the thickness of the metal strip is greater than a threshold thickness, and the strength of the material of the metal strip is greater than a threshold strength;
• and
• for manipulating determination that the metal coil would rest on both support points positioned relative to each other in an initial position, in an unstable equilibrium position when the condition is met;
• a control device is provided for changing the horizontal and/or vertical distance of both support points to each other when the condition is met, so that the metal strip can be deposited on both support points in a stable equilibrium condition.
