Abstract
Abstract In a blanking line including a coil car, an uncoiler, a washing roll, a feed roll, a leveler and a blanking press, an autoloading operation of a coiled steel material in the blanking line can be attained by carrying out automatically various kinds of operations which have been manually made heretofore, such as, for example, operation for loading the coiled steel material on the coil car, operation for supporting the coiled steel material by the uncoiler and the like operations.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
A method of automatically loading coiled material in position in an uncoiler comprising tHe steps of positioning and holding a movable support surface at a loading station spaced from the uncoiler, loading a unit of coiled material on the movable support surface held in the loading position, moving the support surface and the coiled material into a standby position spaced between the loading position and the uncoiler, holding the coiled material in the standby position, monitoring the movement of the coiled material located in the uncoiler and generating a signal when the trailing end portion of the coiled material in the uncoiler has passed a position downstream of the uncoiler, in response to the signal generated by the trailing end portion of the coiled material removed from the uncoiler moving the coiled material on the support surface into the position of the uncoiler, sensing the outside diameter of the coiled material on the support surface in the uncoiler, lifting the coiled material on the support surface and moving the coiled material into a position where the center axis of the coiled material coincides with the center axis of uncoiler cones which support the coiled material on the uncoiler, clamping the coiled material on the uncoiler cones whereby the axis of the coiled material is automatically positioned on the axis of the uncoiler cones and the uncoiled material is supported by the uncoiler.
Claim 2
Independent Claim
232 words
A method of automatically loading coiled material in position in an uncoiler comprising tHe steps of positioning and holding a movable support surface at a loading station spaced from the uncoiler, loading a unit of coiled material on the movable support surface held in the loading position, moving the support surface and the coiled material into a standby position spaced between the loading position and the uncoiler, holding the coiled material in the standby position, monitoring the movement of the coiled material located in the uncoiler and generating a signal when the trailing end portion of the coiled material in the uncoiler has passed a position downstream of the uncoiler, in response to the signal generated by the trailing end portion of the coiled material removed from the uncoiler moving the coiled material on the support surface into the position of the uncoiler, sensing the outside diameter of the coiled material on the support surface in the uncoiler, lifting the coiled material on the support surface and moving the coiled material into a position where the center axis of the coiled material coincides with the center axis of uncoiler cones which support the coiled material on the uncoiler, clamping the coiled material on the uncoiler cones whereby the axis of the coiled material is automatically positioned on the axis of the uncoiler cones and the uncoiled material is supported by the uncoiler.
Claim 3
Dependent Claim
47 words
A method, as set forth in claim 1, characterized therein that after clamping the coiled material on the uncoiler cones, returning the support surface to the loading position for receiving another unit of the coiled material for repeating the operation of loading coiled material onto the uncoiler.
Claim 4
Dependent Claim
38 words
A method, as set forth in claim 2, characterized therein by drawing out the leading end portion of the coiled material mounted on the uncoiler cones and feeding the coiled material from the uncoiler to a working operation.
Claim 5
Dependent Claim
38 words
A method, as set forth in claim 3, characterized therein by aligning the longitudinal center of the coiled material mounted on the uncoiler with the center line of the working operation to which the coiled material is fed.
