Abstract
Abstract A separator-conveyor for the product and scrap of blow-molding apparatus in which the product drops between spaced, upwardly and outwardly convergent guide plates onto the top of closely spaced flat, rigid cleats arranged in edge-to-edge relation longitudinally of an endless conveyor belt. The cleats have their top edges terminate short of the convergent edges of the guide plates and the blow molding products rest on top of the cleats and against the edges of the guide plates, the scrap dropping between the guide plates to each side of the cleats. In one embodiment of the invention spaced, selected of the cleats are of higher altitude and extend into the space between the guide plates to act as pushers for the blow molded products.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
193 words
A separator-conveyor for products discharged from blow molding apparatus, said products including the molded article and the scrap comprising the portions of the parison tube engaged between the walls of the mold sections of the blow molding apparatus, said apparatus including a frame, an endless conveyor belt and means on said frame for supporting said conveyor belt for continuous movement, said belt including an endless flexible base and a plurality of closely spaced, substantially flat sided, erect cleats arranged in a longitudinally extending row on said web at a midpoint of the width thereof and extending the entire length thereof, and outwardly and upwardly tapering guide plates mounted on said frame, one to each side of said row of cleats, said guide plates having their lower edges disposed at a level above the top of said cleats and laterally spaced therefrom, whereby an article discharged from the blow molding apparatus will be supported on the tops of said cleats and on the adjacent edge of at least one of said guide plates, and said scrap will drop between the conveyor edges of said guide plates and said row of cleats onto said base.
Claim 2
Dependent Claim
193 words
A separator-conveyor for products discharged from blow molding apparatus, said products including the molded article and the scrap comprising the portions of the parison tube engaged between the walls of the mold sections of the blow molding apparatus, said apparatus including a frame, an endless conveyor belt and means on said frame for supporting said conveyor belt for continuous movement, said belt including an endless flexible base and a plurality of closely spaced, substantially flat sided, erect cleats arranged in a longitudinally extending row on said web at a midpoint of the width thereof and extending the entire length thereof, and outwardly and upwardly tapering guide plates mounted on said frame, one to each side of said row of cleats, said guide plates having their lower edges disposed at a level above the top of said cleats and laterally spaced therefrom, whereby an article discharged from the blow molding apparatus will be supported on the tops of said cleats and on the adjacent edge of at least one of said guide plates, and said scrap will drop between the conveyor edges of said guide plates and said row of cleats onto said base.
Claim 3
Dependent Claim
50 words
The separator-conveyor of claim 1, wherein selected of said cleats are of greater altitude than the other of said cleats and project into the space between said guide plates and are adapted to engage articles resting on said other cleats for pushing said articles for movement with said conveyor belt.
Claim 4
Dependent Claim
23 words
The separator-conveyor of claim 1, wherein said guide plates are adjustably supported for movement lAterally toward and away from said row of cleats.
Claim 5
Dependent Claim
56 words
The separator-conveyor of claim 1 wherein said conveyor belt comprises a flexible web and a body including a relatively rigid spine and a laterally offset flexible extension at each side of said spine, said body secured by said extension to said web, said spine having spaced slits formed therein extending the full height of said spine.
Claim 6
Dependent Claim
15 words
The separator-conveyor of claim 4 wherein said slits comprise triangular darts cut into said spine.
Claim 7
Dependent Claim
74 words
The separator-conveyor of claim 1, wherein said endless conveyor belt comprises an endless flexible web and a superposed body comprising a relatively rigid, upright spine having laterally extending flexible base portions to each side thereof, said body secured to said web by said base portions with said spine extending longitudinally thereof; said spine having relatively closely spaced slits formed therein extending from its outer edge to its base to thereby render said belt flexible.
Claim 8
Dependent Claim
17 words
The separator-conveyor of claim 6, wherein said slits comprise triangular shaped cut-out darts formed in said spine.
Claim 9
Dependent Claim
68 words
The separator-conveyor of claim 7, wherein said body includes relatively longer body sections having spines of uniform relatively low altitude and of a length to provide a plurality of said cleats, said sections interspersed by body sections having spines of relatively greater altitude and of a length to provide a single cleat of a height to extend into the space between said guide plates above their lower edges.
Claim 10
Dependent Claim
100 words
An endless conveyor belt for a separator-conveyor of the character described, comprising an endless flexible web and a superposed body on said web, said body comprising a relatively rigid spine and laterally offset flexible base portion to each side of said spine, said body secured to said endless flexible web by said flexible base portions with said spine extending longitudinally of said web; said spine having relatively closely spaced slits formed therein extending from its outer edge inwardly thereinto to said base, to form a plurality of tooth-like cleats, and thereby render said endless belt flexible around a supporting drum.
Claim 11
Dependent Claim
100 words
An endless conveyor belt for a separator-conveyor of the character described, comprising an endless flexible web and a superposed body on said web, said body comprising a relatively rigid spine and laterally offset flexible base portion to each side of said spine, said body secured to said endless flexible web by said flexible base portions with said spine extending longitudinally of said web; said spine having relatively closely spaced slits formed therein extending from its outer edge inwardly thereinto to said base, to form a plurality of tooth-like cleats, and thereby render said endless belt flexible around a supporting drum.
Claim 12
Dependent Claim
17 words
The endless conveyor belt of claim 9, wherein said slits comprise triangular darts cut into said spine.
Claim 13
Dependent Claim
51 words
The endless conveyor claim 10, wherein said superposed body comprises sections having a spine of relatively lower altitude and of a length to provide a plurality of said cleats therein interspersed by sections having a spine of relatively greater altitude and of a length to provide a single of said cleats.
