Abstract
Abstract An apparatus for carrying and separating articles includes a pair of parallel endless belts made of an elastic material, a plurality of carrying rods bridging the two belts in the transversal direction and carriers each engaged with adjacent carrying rods and capable of sliding relative thereto in transversal directions. Articles are put on the carriers and are separated with displacement of the carriers in transversal directions. The belt has a core buried in it and incapable of elongation or contraction in the length direction. The pair of belts have carrying rod mounting pins projecting from their opposed edges. These pins are coincident with the center of the cores. They each have an engaged portion and an embedded portion, the engaged portion being engaged in an end of a carrying rod, the embedded portion being embedded in a belt. The engaged portion and embedded portion are eccentric with each other, the embedded portion being embedded in a portion not interfering with the core, the engaged portion being found in the vicinity of the core.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
An apparatus for carrying and separating articles, comprising: a pair of parallel carrying means; a plurality of carrying rods bridging said pair of carrying means; a number of carriers each provided between adjacent ones of said carrying rods for relative sliding movement; and separating means for moving said carriers in transverse directions; wherein each said carrying means includes: an endless belt with teeth formed of an elastic material, a core embedded in said elastic material, said core being flexible but substantially incapable of elongation or contraction in the length direction, a plurality of pins projecting from the inner side surface of said belt, and opposite ends of said carrying rods are mounted on said belts by said pins; each of said pins has an embedded portion and an engaged portion, said embedded portion being embedded in a region of the associated belt not occupied by the core, said engaged portion being fitted in an end of the associated carrying rod; and said embedded portion of each pin has a crescent sectional profile, a plane surface of said embedded portion corresponding to the chord of the crescent section is in close contact with one surface of said core, and a stepped portion is provided in each pin in a region connecting said embedded portion and the remaining part of the pin, said stepped portion abutting said inner side surface of each belt.
Claim 2
Independent Claim
231 words
An apparatus for carrying and separating articles, comprising: a pair of parallel carrying means; a plurality of carrying rods bridging said pair of carrying means; a number of carriers each provided between adjacent ones of said carrying rods for relative sliding movement; and separating means for moving said carriers in transverse directions; wherein each said carrying means includes: an endless belt with teeth formed of an elastic material, a core embedded in said elastic material, said core being flexible but substantially incapable of elongation or contraction in the length direction, a plurality of pins projecting from the inner side surface of said belt, and opposite ends of said carrying rods are mounted on said belts by said pins; each of said pins has an embedded portion and an engaged portion, said embedded portion being embedded in a region of the associated belt not occupied by the core, said engaged portion being fitted in an end of the associated carrying rod; and said embedded portion of each pin has a crescent sectional profile, a plane surface of said embedded portion corresponding to the chord of the crescent section is in close contact with one surface of said core, and a stepped portion is provided in each pin in a region connecting said embedded portion and the remaining part of the pin, said stepped portion abutting said inner side surface of each belt.
Claim 3
Dependent Claim
20 words
The apparatus according to claim 1, wherein said pins are mounted on said belt at locations corresponding to said teeth.
Claim 4
Dependent Claim
81 words
The apparatus according to claim 2, wherein each belt has raised portions formed on a side of said core opposite to the side on which said teeth are provided and at locations corresponding to said teeth; embedding holes extending in the transversal direction of the belt are formed at locations corresponding to said raised portions; and each pin is fitted in each embedding hole, and clamped and secured in position by an elastic force of the elastic material of the belt.
Claim 5
Dependent Claim
27 words
The apparatus according to claim 1, wherein said engaged portion of each pin is deviated toward the tooth side with respect to the core of the belt.
Claim 6
Dependent Claim
166 words
An endless belt assembly with teeth for use with apparatus for carrying and separating articles, wherein said belt assembly comprises: an endless belt made of an elastic material and having a core embedded in said elastic material, said core being flexible but substantially incapable of elongation and contraction in the length direction; a plurality of pins projecting from one side surface of said belt and coincident in position with the center of said core in the thickness direction thereof, each pin including: an embedded portion having a crescent sectional profile, said embedded portion being embedded in a region of said belt which is not occupied by said core, a plane surface of said embedded portion corresponding to the chord of the crescent section being in close contact with one surface of said core; an engaged portion; and a stepped portion provided in a region connecting said embedded portion and the remaining part of the pin, said stepped portion abutting an inner side surface of each belt.
Claim 7
Dependent Claim
166 words
An endless belt assembly with teeth for use with apparatus for carrying and separating articles, wherein said belt assembly comprises: an endless belt made of an elastic material and having a core embedded in said elastic material, said core being flexible but substantially incapable of elongation and contraction in the length direction; a plurality of pins projecting from one side surface of said belt and coincident in position with the center of said core in the thickness direction thereof, each pin including: an embedded portion having a crescent sectional profile, said embedded portion being embedded in a region of said belt which is not occupied by said core, a plane surface of said embedded portion corresponding to the chord of the crescent section being in close contact with one surface of said core; an engaged portion; and a stepped portion provided in a region connecting said embedded portion and the remaining part of the pin, said stepped portion abutting an inner side surface of each belt.
Claim 8
Dependent Claim
83 words
The belt assembly according to claim 5, wherein each belt has raised portions formed on one side of said core opposite to the other side on which said teeth are provided and at locations corresponding to said teeth; embedding holes extending in the transversal direction of the belt are formed at locations corresponding to said raised portions; and each pin is fitted in each embedding hole, and clamped and secured in position by an elastic force of the elastic material of each belt.
