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 rivet collating system comprising:
a plurality of connected bodies;
an upper plate and a lower plate of each body;
a plurality of rivets associated with each body, the rivets including rivet heads held between the upper and lower plates of the body;
vertically aligned apertures of the upper and lower plates that are configured to allow the rivets to be driven out from the bodies;
a plurality of flap portions of the lower plates supporting the rivet heads; and
take-up spaces of the lower plates adjacent the flap portions and spaced from the lower plate apertures by the flap portions, the take-up spaces narrowing as the flap portions shift apart to permit the rivet heads to be driven out from the bodies.
2. The rivet collating system of claim 1 wherein the lower plates include reduced thickness hinge portions about which the flap portions pivot as the rivet heads are driven from the bodies.
3. The rivet collating system of claim 2 wherein the upper plates include drive heads above the rivet heads for driving the rivet heads out of the bodies, the drive heads including upper, enlarged portions configured to contact the hinge portions and resist passage of the drive heads beyond the lower plates.
4. The rivet collating system of claim 1 wherein the lower plates include substantially flat upper surfaces and substantially flat lower surfaces and the flap portions include inclined surfaces extending from the upper surfaces of the lower plates downwardly along lower portions of the rivet heads.
5. The rivet collating system of claim 1 wherein the lower plates have an upper surface, a lower surface, and a thickness therebetween and the flap portions and take-up spaces are within the thicknesses of the lower plates.
6. The rivet collating system of claim 1 wherein the bodies are connected by frangible bridges.
