摘要： An apparatus is provided for feeding fabric workpieces one at a time from the top of a stack of like workpieces having a first rough side and a second smooth side, the workpieces being stacked with alternating sides up. A computer controlled picker is used to separate the top workpiece from the remaining workpieces in the stack, and for depositing the workpiece on a downstream conveyor. An ultrasonic face detector is mounted above the first conveyor for determining whether the side of the workpiece facing the face detector--the top surface--is relatively rough or relatively smooth. A pivoting feeder/inverter is provided at the end of the first conveyor. If the workpiece has the desired side up for subsequent sewing operations, the inverter/conveyor is placed in a first position so that the workpiece is directed into a sandwich belt type conveyor which will not change the orientation of the workpiece. If the workpiece has the desired side down, the feeder/inverter is pivoted to a second position to enable the workpiece to enter an inverter conveyor which will rotate the workpiece 180 degrees about an axis along the direction of travel to place the workpiece in the correct orientation for the subsequent sewing operation. Thus, this apparatus takes all of the fabric workpieces from a stack in which the sides facing up alternate, and automatically places all of them in the same orientation prior to arrival at a sewing station.

摘要翻译： 一种装置，用于从具有第一粗糙面和第二平滑侧的类似工件的堆叠的顶部一次一个地馈送织物工件，工件以交替的侧面向上堆叠。 使用计算机控制的拾取器将顶部工件与堆叠中的其余工件分离，并将工件沉积在下游输送机上。 超声波面部检测器安装在第一传送器上方，用于确定面向面部检测器的工件的侧面（顶部表面）是相对粗糙还是相对光滑的。 在第一输送机的端部设置有枢转进给器/逆变器。 如果工件具有所需的侧面朝上用于随后的缝纫操作，则将变频器/输送机置于第一位置，使得工件被引导到不会改变工件的取向的夹心带式输送机。 如果工件具有所需的侧面向下，则进给/转换器枢转到第二位置，以使工件能够进入逆变器输送机，该输送机将使工件沿着行进方向绕轴线旋转180度，以将工件放置在正确的位置 方向为随后的缝制操作。 因此，该装置将所有的织物工件从侧面朝上交替的堆叠中取出，并且在到达缝纫台之前自动将它们全部放在相同的方位。
