Abstract
Transfer apparatus for a workpiece such as a metal slab, bloom or coil of metal strip comprises a carriage supported on a substantially horizontal beam. The beam is displaceable in the direction of its length and the ends of a flexible cable are connected to opposite ends of the carriage with a reach of the cable extending substantially parallel to the length of the beam. An intermediate point of the cable is firmly anchored so that displacement of the beam causes the carriage to be displaced along the beam as well as its movement with the beam. The beam can also be raised and lowered.
Claims6
Transfer apparatus comprising:
- an elongate beam arranged substantially horizontal on supports which permit the beam to be displaced in the direction of its length,
- means for displacing the beam in the direction of its length,
- a carriage providing a support for a workpiece,
- said carriage being supported on the beam so as to be displaceable therealong,
- an elongate flexible member connected at its ends to opposite ends of the carriage with a reach of the flexible member extending substantially parallel to the length of the beam, and
- anchor means fixed relative to the beam and connected to said flexible member at a position intermediate the ends of said member, the apparatus being so constructed and arranged that displacement of the beam relative to the anchor means causes the carriage to be displaced along the beam in addition to its movement with the beam.
Transfer apparatus comprising:
- an elongate beam arranged substantially horizontal on rollers,
- a pair of stationary supports arranged parallel to and one on each side of the beam, the upper surfaces of each of said supports providing a workpiece support surface,
- means for displacing the beam in the direction of its length,
- a carriage providing a support for a workpiece,
- said carriage being supported on the beam so as to be displaceable thereby,
- an elongate flexible cable connected at its ends to opposite ends of the carriage and extending around pulleys positioned at the ends of the beam with a reach of the cable extending beneath and substantially parallel to the length of the beam,
- anchor means fixed relative to the beam and connected to said reach of the cable at substantially the mid point of the cable, and
- means for raising and lowering said rollers in unison between positions in which the workpiece support provided by the carriage is above and below the support surfaces of the stationary supports respectively.
