    • One end of a pull rod (66) is pivotably attached to a lever (82), and the other end of rod (66) has a T-shaped slot (70) for receiving the head (28) and part of the shaft (24) of a plastic blind rivet fastener (22). Rod (66) slides axially in a tube (54) which has a radial end wall (60) with a slot (62) for slidably receiving the shaft (24). A spring (76) biases the rod (66) into a fastener-receiving position adjacent to wall (60). The lever (82) is squeezed toward a handle (56) to pull the rod (66) away from the wall (60) and the fastener head (28) axially inwardly. The abutment of the wall (60) against a collar (36) on shaft (24) slides collar (36) along shaft (24) to force a portion of a sleeve (30) on shaft (24) radially outwardly. A bent tube (104) may be provided instead of the straight tube (54). The pull member (110) received in the tube (104) has two rod portions (112,120) on oposite sides of the bend (106). These portions (112,120) are connected by a flexible cable (116).

    • Disclosed is device (10) for orienting and conveying a headed fastener (14), wherein the device is positioned beneath any suitable dispenser (12) whereby headed fasteners are removed from a supply container and successively dropped with random orientation onto the device. The device (10) is configured to receive the headed fasteners (14) within a selected groove (32, 132) so that the headed fastener will assume a predetermined orientation within the device. The oriented fastener is then conveyed from the point it is received in the groove to a conduit (55, 57) which directs the headed fastener into the feeder tube (16) of the fastening machine. The fasteners are rotated as they are conveyed along the device in order to create a gyroscopic effect in the fastener as a means of maintaining the relative orientation of the fastener as it moves through the groove toward the feeder tube.
    • 公开了一种用于定向和传送头部紧固件(14)的装置(10),其中该装置位于任何合适的分配器(12)下方,由此朝向的紧固件从供应容器移除并随机取向连续地落到装置上。 装置(10)构造成在所选择的凹槽(32,132)内接收头部紧固件(14),使得头部紧固件将在装置内呈现预定取向。 然后将定向的紧固件从其被容纳在凹槽中的点传送到将头部紧固件引导到紧固机器的给料管(16)中的导管(55,57)。 当紧固件沿着装置传送时,紧固件被旋转以便在紧固件中产生陀螺效应,作为当紧固件通过凹槽朝向馈送管移动时保持紧固件的相对定向的手段。
