Abstract:
1. An apparatus for sorting textile workpieces comprising: an enclosed workpiece flow pathway comprising, a tube having a mouth for receiving a textile workpiece into said flow pathway, a diverter connected to said tube, said diverter having at least first and second exit pathways from said diverter and said diverter having a selectably repositionable diversion tube for receiving a workpiece entering said diverter and said diversion tube providing selectable directing of said workpiece to at least first and second exit pathways, means for selectably repositioning said diversion tube, a receiving arm connected to one of said first and second exit pathways of said diverter, a sorting bin for receiving a workpiece from said receiving arm, said sorting bin is an inverted cone having a cylindrical section extending upwardly from said cone base and said cone having an apical portion terminating in a flat door generally covering the diameter of the cone near the apex of the cone and said receiving arm being connected in tangential arrangement to the side of said cylinder section and, a motor operated fan for generating suction airflow within said flow pathway to provide movement of said workpiece through said flow pathway said motor having a variable frequency drive control connected thereto said variable frequency drive being responsive to a programmable controller that detects the number of tubes operating in the apparatus to direct the frequency of the variable frequency drive control in response thereto, and a brake operably connected to said motor to rapidly reduce or terminate fan rotation by said motor and the suction generated by said fan in response to said variable frequency drive control.
