Claims3
A shear front feed system for feeding sheet metal into the front of a shear,
- said system including conveyor means for receiving said sheet metal and transferring it to the front of the shears for shearing operations,
- said conveyor means having a sheet metal receiving end remote from said shears and a sheet metal transferring end adjacent said shears,
- said transfer end being separated from said receiving end by the length of said conveyor means,
- said conveyor means comprising a plurality of parallel spaced apart powered roller means for moving the sheet metal in a substantially straight line from the receiving end to the transferring end,
- each of said roller means extending from one side of the conveyor means to the opposite side transverse to the length of the conveyor means from the receiving end to the transferring end,
- ball transfer means free to rotate in any direction mounted on said conveyor means for facilitating the movement of the sheet metal from the normal straight line motion actuated by the roller means to thereby present the sheet metal at a selected one of various angles to the blade of the shear;
- and means for lifting said ball transfer means to a position above said powered roller means to separate said sheet metal from said roller means for reorientation upon said ball transfer means,
- said ball transfer means being arranged in spaced apart rows with said rows being located transversely between each of said spaced apart roller means.
