Abstract
Abstract AN ARTICLE-CONVEYING DEVICE FOR PROVIDING DELAY IN THE CONVEYANCE OF AN ARTICLE WHEN NECESSARY WITHOUT INTERRUPTING THE SPEED OF THE ARTICLE. THE INVENTION PROVIDES A REGULAR CIRCULAR PATH AND AN AUXILIARY CIRCULAR DELAY PATH TANGENT THERETO IN FIG. 8 FORM WITH MEANS TO SELECT WHICH PATH AN ARTICLE IS TO FOLLOW. DETECTION OF THE PRESENCE OF ARTICLES IN EITHER PATH IS BY PHOTOCELLS WHICH RELAY INFORMATION TO A CENTRAL CONTROL WHICH CONTROLS THE PATH-SELECTION MEANS. AN ARTICLE WHICH IS TO DELAYED IS TAKEN OUT OF THE REGULAR PATH AND GUIDED INTO THE AUXILIARY PATH TO REMAIN THEREIN FOR AT LEAST ONE REVOLUTION OF THE PATH, AND IS RETURNED TO CONTINUE ITS JOURNEY IN THE REGULAR PATH WHENEVER THE CENTRAL CONTROL SO DIRECTS.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
In an article-conveying device, the arrangement comprising: a. first means, defining a curved continuous first path for imparting movement to articles along said first path; b. second means defining a substantially circular continuous second path, said second means including a drum the peripheral surface of which is positioned proximate said first path so as to provide said first and second paths with a coincident point of tangency; and c. switch means for selectively guiding articles from said first path into said second path and vice versa, said switch means including a two-position points mechanism positioned between said first and second paths at said coincident point of tangency, said points mechanism being arranged in the one position to permit articles in the first path to remain therein and articles in the second path to return to the first path, and in the other position permit articles in the first path to be conveyed into the second path and for articles already in the second path to remain therein, said switching means further including third means for detecting articles in either path and electromagnetic means responsive to said detecting means for switching said switch means in accordance with the transit time period requirement for each article between the input and output of said first path.
Claim 2
Dependent Claim
213 words
In an article-conveying device, the arrangement comprising: a. first means, defining a curved continuous first path for imparting movement to articles along said first path; b. second means defining a substantially circular continuous second path, said second means including a drum the peripheral surface of which is positioned proximate said first path so as to provide said first and second paths with a coincident point of tangency; and c. switch means for selectively guiding articles from said first path into said second path and vice versa, said switch means including a two-position points mechanism positioned between said first and second paths at said coincident point of tangency, said points mechanism being arranged in the one position to permit articles in the first path to remain therein and articles in the second path to return to the first path, and in the other position permit articles in the first path to be conveyed into the second path and for articles already in the second path to remain therein, said switching means further including third means for detecting articles in either path and electromagnetic means responsive to said detecting means for switching said switch means in accordance with the transit time period requirement for each article between the input and output of said first path.
Claim 3
Dependent Claim
112 words
An article-conveying device comprising first means for imparting movement to an article along a substantially circular closed loop first path and to selectively direct the article in and out of said first path, said first means including a rotatable cylindrical drum and an associated holding arrangement to hold the article in contact with the peripheral surface of said drum, wherein said peripheral surface of said drum is delimited at one side by a peripheral collar and said holding arrangement includes freely rotatable rollers mounted with respect to said drum such that contact is made by said rollers with said peripheral surface and the article located thereon is urged toward said peripheral collar.
Claim 4
Dependent Claim
112 words
An article-conveying device comprising first means for imparting movement to an article along a substantially circular closed loop first path and to selectively direct the article in and out of said first path, said first means including a rotatable cylindrical drum and an associated holding arrangement to hold the article in contact with the peripheral surface of said drum, wherein said peripheral surface of said drum is delimited at one side by a peripheral collar and said holding arrangement includes freely rotatable rollers mounted with respect to said drum such that contact is made by said rollers with said peripheral surface and the article located thereon is urged toward said peripheral collar.
Claim 5
Dependent Claim
25 words
The article-conveying device according to claim 2 wherein the axial width of said peripheral surface is smaller than the smallest width of the articles conveyed.
Claim 6
Dependent Claim
28 words
The article-conveying device according to claim 2 wherein it includes second means to impart movement to said article along a second path tangent to said closed loop path.
Claim 7
Dependent Claim
45 words
The article-conveying device according to claim 4 wherein said first and second means include a common points mechanism which is mounted at the point of tangency of said paths and which is adapted to direct said article into or out of said closed loop path.
Claim 8
Dependent Claim
22 words
The article-conveying device according to claim 5 wherein said first and second means impart movement to said article at the same speed.
Claim 9
Dependent Claim
25 words
The article-conveying device according to claim 6 wherein the direction of article movement associated with said first and second paths is respectively counterclockwise and clockwise.
