Collating system for conveyor belt rivets and method
A collating system for rivets is provided that includes a rivet holder for supporting rivets in a predetermined pattern. In one form, the rivet holder includes a body having cavities for supporting the rivets therein. The rivet holder body includes a top plate member and a bottom plate member. The rivet holder has drive heads connected to the top plate member via frangible portions and the bottom plate member has retaining webs disposed below the drive heads. The top and bottom plates are secured together to capture heads of the rivets between the drive heads and retaining webs. The drive heads may be driven downward to drive the rivet heads from the rivet holder and into bores of a guide block with the retaining webs flexing to release the rivet head from the lower bottom plate member. A method of using the rivet collating system is also disclosed.
1. A method of positioning rivets in bores of a guide block, the method comprising:
positioning a lower surface of a holder on a guide block, the holder having an upper surface and a predetermined thickness between the upper surface and the lower surface;
impacting upper portions of the holder with a tool to drive heads of rivets out from the holder and into the bores; and
deflecting flap portions about hinge portions of the holder into grooves of the holder as the rivet heads are driven out from the holder, the hinge portions having a thickness that is reduced relative to the predetermined thickness of the holder.
2. The method of claim 1 wherein impacting the upper portions of the holder with the tool includes impacting upper portions of an upper plate of the holder; and
deflecting flap portions of the holder into grooves of the holder includes deflecting flap portions of a lower plate portion of the holder into grooves of the lower plate portion.
3. The method of claim 1 wherein deflecting flap portions of the holder includes camming radially outer portions of the rivet heads against lands of the flap portions.
4. The method of claim 1 wherein deflecting flap portions of the holder includes pivoting the flap portions about the hinge portions of the holder above the grooves.
5. The method of claim 1 wherein impacting upper portions of the holder with the tool include impacting drive heads of the holder with the tool; and
abutting enlarged portions of the drive heads against portions of the holder above the grooves to restrict the drive heads from falling out of the holder.
6. A method of positioning rivets in bores of a guide block, the method comprising:
positioning a lower portion of a holder on a guide block;
impacting upper portions of the holder with a tool to drive heads of rivets out from the holder and into the bores; and
deflecting flap portions of the holder into grooves of the holder as the rivet heads are driven out from the holder,
wherein positioning the lower portion of the holder on the guide block includes positioning a lower surface of the holder on the guide block while the flap portions of the holder are outside of the bores of the guide block.
7. The method of claim 1 wherein impacting upper portions of the holder with the tool includes impacting drive heads of the holder to drive the rivet heads out from the holder.
