A method and apparatus for locating improperly positioned or bent rolls among a set of rolls which define a confined path of travel for a workpiece, particularly useful for checking a straight or curved roll-rack of a continuous-casting machine. The apparatus may be propelled through the path defined by the rolls by any suitable mechanism. For example, as applied to a roll-rack, the apparatus may be attached to the upper end of a starter bar and propelled with the bar through the rack, or the apparatus may be suspended from a hoist and pulled through the rack. The apparatus includes a housing and means within the housing for measuring the gap between work-engaging faces of the rolls and/or, when used with a curved roll-rack, means for measuring the angular relation of adjacent bottom rolls. The latter measurement is used in determining whether the work-engaging faces lie on arcs of the intended radii. Bent rolls are located by observing different measurements when the apparatus is moved in opposite directions through the path of travel.
An apparatus for locating improperly positioned rolls among a set of rolls which are arranged in opposed pairs and have work-engaging faces defining a confined path of travel for a workpiece, said apparatus comprising a housing movable along said path, means carried by said housing at opposite faces thereof for abutting said work-engaging faces and guiding said housing, and a plurality of gap sensors carried by said housing and including heads supported for relative movement normal to the direction of movement of said housing along said path and adapted to contact the work-engaging faces of the individual roll-pairs successively at a plurality of locations along the length of the rolls, and transducer means operatively connected with said heads for transmitting signals representative of the measurements of the gaps between the work-engaging faces of each roll-pair contacted by said heads.
An apparatus for locating improperly positioned rolls in a curbed roll-rack, the rolls of which are arranged in opposed pairs and have work-engaging faces defining a confined path of travel for a workpiece and lying on arcs of predetermined radii, said apparatus comprising a housing movable along said path, at least one gap sensor carried by said housing for transmitting signals representative of the gap measurement between the rolls of the various pairs, and angle-measuring means carried by said housing for transmitting signals representative of the angles of lines tangent to work-engaging faces of adjacent rolls and thereby indicating whether the work-engaging faces lie on arcs of the intended radii.
An apparatus for locating improperly positioned rolls in a curved roll-rack in which the rolls are arranged in opposed pairs and have work-engaging faces lying on arcs of predetermined radii, said apparatus comprising a housing movable through the roll-rack, guide means on said housing adapted to abut two adjacent rolls and lie on a line tangent to the work-engaging faces thereof, and angle-measuring means in said housing for indicating the angle at which said guide means lies and thereby indicating whether the work-engaging face of each roll lies on an arc of the intended radius.
A method of locating improperly positioned rolls among a set of rolls which are arranged in opposed pairs and have work-engaging faces defining a confined path of travel for a workpiece, said method comprising moving an apparatus along said path, transmitting signals from said apparatus representative of the measurement of the gap separating the work-engaging faces of rolls of each pair in succession at a plurality of locations along the length of the rolls during each pass of the apparatus along said path, and recording said signals.
A method of locating improperly positioned rolls among a set of rolls which are arranged in opposed pairs and have work-engaging faces defining a confined path of travel for a workpiece, said method comprising moving an apparatus along said path, transmitting signals from said apparatus representative of the measurement of the gap separating the work-engaging faces of rolls of each pair in succession, transmitting signals representative of the angles of lines tangent to each adjacent pair of work-engaging faces, and recording both the gapmeasurement signals and the angle-measurement signals.
An apparatus for locating improperly gapped rolls among a set of rolls arranged in opposed pairs and having work-engaging faces with a gap therebetween defining a confined path of travel for a workpiece, said apparatus comprising a supporting structure, means carried by said structure for contacting the work-engaging faces of each pair of rolls at opposite sides of the gap and thereby guiding the structure as it moves along said path, a plurality of gap-sensing means carried by said structure for measuring the gap between each pair of rolls in succession at a plurality of locations along the length of the rolls, and means connected with said gap-sensing means for transmitting signals representative of the measurements.
