Abstract
A tension springs separation device for use in a system for automatically mounting tension springs to a seat frame of a seat for an automobile. In the separation device, there are provided two narrow portions in a feed passage in a part feeder, each of which has a width permitting only one tension spring to pass therethrough in the longitudinal direction, and there are provided two projected ramp portions each of which has a level difference slightly larger than the outside of the tension spring, whereby a large number of tension springs loaded into the part feeder can be sent out one by one sequentially.
Claims9
A sparation device for separating tension springs from each other, comprising:
- two narrow portions located in an upwardly inclined spring feed conduit of a part feeder and having a width permitting only one tension spring to pass therethrough in the longitudinal direction, said tension spring having two hook portions at the two ends thereof;
- and,
- two projected ramp portions provided in said conduit of said part feeder which cause a temporary elevation of the tension springs moving over said ramp portions relative to, the level of the tension springs immediately before and after passing said ramp portions characterized in that, when said tension springs are transferred, in said narrow portions the tension springs that protrude overlappingly beyond said narrow portions are caused to fall down to the bottom portion of said part feeder, and the end hook portions of two tension springs entangled with each other can be separated from each other at said projected ramp portions.
