Abstract
Abstract An article placement system for applying a plurality of articles to a substrate, each article placed in a different location and perhaps at a different angular orientation on said substrate. The system includes a base with a walking beam mounted to the base which has an axis of bi-directional movement, and a direction of length along the axis. A plurality of article transfer members is mounted to the walking beam at axially spaced-apart locations from one another. Conveyor means extends axially beneath the article transfer means for conveying substrates to positions beneath successive ones of the article transfer means. A plurality of article supply members is mounted to the base. Each has a respective delivery point where it provides an article to a respective one of the article transfer means. Positioning means is provided for locating the article transfer members and the article supply members relative to each other to provide for selectively adjustable placement of the articles. The conveyor means is stepped intermittently beneath the article transfer members which oscillate as a group with the walking beam to pick up an article and deposit it on a respective substrate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
274 words
An article placement system for applying a plurality of articles to a substrate, each article being placed at a different location on said substrate, said system comprising: a base; a walking beam mounted to the base, said walking beam having an axis of bi-directional movement, and a dimension of length along said axis; a plurality of article transfer members mounted to said walking beam at axially spaced-apart locations from one another; conveyor means extending axially beneath said article transfer members for conveying substrates to positions beneath successive ones of said article transfer means; a plurality of article supply members, each having a respective delivery point where it provides an article to a respective one of said article transfer members; drive means axially bi-directionally moving said walking beam, and thereby all of the article transfer members simultaneously by a unit distance, between a respective delivery point and a respective deposit point and reversely; stepper means intermittently moving said conveyor means by an indexing distance, whereby to move all substrates simultaneously beneath successive deposit points; supply positioning means mounting each said article supply member to the base whereby its respective delivery point is axially and laterally adjustable; transfer positioning means mounting each said article transfer member to said walking beam for axial and lateral adjustment to meet the respective delivery point; whereby said stepper means intermittently operates to cause the conveyor means to move the substrates beneath successive deposit points, and the walking beam oscillates to move the article transfer means from the delivery point of their respective article supply member where they pick up an article, to their respective deposit point where they deposit it.
Claim 2
Dependent Claim
274 words
An article placement system for applying a plurality of articles to a substrate, each article being placed at a different location on said substrate, said system comprising: a base; a walking beam mounted to the base, said walking beam having an axis of bi-directional movement, and a dimension of length along said axis; a plurality of article transfer members mounted to said walking beam at axially spaced-apart locations from one another; conveyor means extending axially beneath said article transfer members for conveying substrates to positions beneath successive ones of said article transfer means; a plurality of article supply members, each having a respective delivery point where it provides an article to a respective one of said article transfer members; drive means axially bi-directionally moving said walking beam, and thereby all of the article transfer members simultaneously by a unit distance, between a respective delivery point and a respective deposit point and reversely; stepper means intermittently moving said conveyor means by an indexing distance, whereby to move all substrates simultaneously beneath successive deposit points; supply positioning means mounting each said article supply member to the base whereby its respective delivery point is axially and laterally adjustable; transfer positioning means mounting each said article transfer member to said walking beam for axial and lateral adjustment to meet the respective delivery point; whereby said stepper means intermittently operates to cause the conveyor means to move the substrates beneath successive deposit points, and the walking beam oscillates to move the article transfer means from the delivery point of their respective article supply member where they pick up an article, to their respective deposit point where they deposit it.
Claim 3
Dependent Claim
41 words
An article placement system according to claim 1 in which said article transfer means includes a pick up element, said pick up element being adapted to engage and release respective articles, and to move vertically to raise and lower said articles.
Claim 4
Dependent Claim
39 words
An article placement system according to claim 2 in which said pick up element comprises a rod having a respective axis, said rod being movable along said axis; and motor means for moving said rod along its said axis.
Claim 5
Dependent Claim
52 words
An article placement system according to claim 3 in which said rod has a tip, and a passage extending to and opening onto said tip, said passage being adapted to be connected to suction pressure to cause an article to be engaged by the rod, and disconnected therefrom to release the article.
Claim 6
Dependent Claim
41 words
An article placement system according to claim 4 in which said passage extends axially in the rod, and has a side-tapped port, and in which a pair of seals seal against said rod on axially opposite sides of said side-tapped port.
Claim 7
Dependent Claim
38 words
An article placement system according to claim 3 in which said motor means comprises a piston-cylinder assembly operatively engaged to said rod, and means for exerting fluid pressure on said assembly for moving said rod along its axis.
Claim 8
Dependent Claim
27 words
An article placement system according to claim 2 in which said pick up element is rotatable to determine the angular position of the article on the substrate.
Claim 9
Dependent Claim
39 words
An article placement system according to claim 7 in which said pick up element comprises a rod having a respective axis, said rod being movable along said axis; and motor means for moving said rod along its said axis.
Claim 10
Dependent Claim
40 words
An article transfer system according to claim 8 in which said rod includes axial splines, and in which rotation means comprises gear means engageable to said splines which enable axial movement of said rod, and which can rotate the rod.
Claim 11
Dependent Claim
30 words
An article transfer system according to claim 9 in which said gear means comprises a rack, and in which means is provided to move the rack to rotate the rod.
Claim 12
Dependent Claim
30 words
An article transfer system according to claim 10 in which stop means is provided to limit the movement of the rack, and thereby establish a rotary position of the rod.
Claim 13
Dependent Claim
