Abstract
In order to correctly detect whether an individually supplied part is actually mounted on a part-receptive member, a part detector is disposed at a position close to a part-holding member of a part-supply rod. Positionwise relationship between this part detector and the part-receptive member is predetermined in order that the part mounted on the part-receptive member can activate operation of the above-identified part detector to generate a signal for identifying presence of the delivered part while the part-supply rod retreats.
Claims3
A device for detecting presence or absence of an individually supplied part in a part-supply rod, wherein a part-detecting means is set to a position close to a part-holding member of said part-supply rod, and wherein a positionwise relationship between said part-detecting means and a part-receptive member is predetermined in order that an individual part mounted on said part-receptive member can activate operation of said part-detecting means to generate a signal for identifying presence of said individual part in said part-supply rod;
- wherein an axial-directional groove is formed on an external circumferential surface of said part-supply rod;
- and
- further wherein a cable extended from said part-detecting means is accommodated in said groove.
An assembly for, detecting the presence of absence of an individually supplied part, the assembly comprising:
- a reciprocating part-supply rod for supplying a preselected part to a pickup point;
- part-detecting means positioned adjacent a part holding means of the part-supply rod for detecting the presence of a part on a part-receptive member, :the part-receptive member having a preselected positional relationship to the part-detecting means for causing activated operation of the part-detecting means by the part positioned in the part-supply rod;
- wires connected at first ends thereof to an output of the part-detecting means for carrying an electrical signal indicative of activated operation of the part-detecting means;
- means formed on an external circumferential surface of the part-supply rod for receiving the wires;
- an insulated conductive plate secured to the part-supply rod, second ends of the wires being connected to the plate;
- a conductive shoe held in contact with the conductive plate for conducting the electrical signal from the plate to a control circuit, indicating the presence or absence of said individual part in the part-supply rod, while the part-supply rod withdraws from the pickup point.
