Abstract
Abstract An apparatus for dividing a row of tierlike superposed flat articles, particularly newspapers, which row rests on a main conveyor belt, into two dividing rows. The apparatus is characterized by at least one swordlike slide having an operating mechanism for insertion of the slide between two articles lying one on top of the other. In addition, two rollers (dividing rollers) are provided having a friction coating thereon and are arranged below a table and extend with their upper sides through slots in the table. The upper sides of the rollers are positioned lower than the transporting surface of the conveyor belt and the axes of which are arranged parallel to the direction of movement of the main conveyor belt or V-shaped in such a manner that the dividing rollers at an increasing distance from the main conveyor belt approach one another. A movable roller cover is provided which is interchangeably associated with the one or the other of the dividing rollers for covering same. Conveyor belts (divided flow conveyor belts) are connected after the dividing rollers and a counting device is provided for the articles conveyed by the main conveyor belt or the divided flow conveyor belts. A control and operating mechanism is provided for periodically moving the slide and the roller cover in such a manner that the roller cover is changed over to a different dividing roller when the slide holds the papers away from the dividing rollers after a predetermined number of articles have been conveyed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
214 words
In an apparatus for dividing a single row of tierlike superposed flat articles into two divided rows, the combination comprising: first conveyor means for conveying said tierlike superposed flat articles in said single row toward an end thereof; second and third conveyor means each adapted to convey said tierlike superposed flat articles away from said end of said first conveyor means; means for supporting said second and third conveyor means in a generally coplanar relationship; drive means adjacent said end of said first conveyor means for driving said tierlike superposed flat articles toward and onto a select one of said second and third conveyor means; and diverting means for diverting the movement of said tierlike superposed flat articles exiting said firsT conveyor means from engaging said drive means during the interval of time required to shift the flow of tierlike superposed flat articles from one of said second and third conveyor means to a selected other of said second and third conveyor means, said diverting means thereafter depositing said articles onto said drive means and said selected one of said second and third conveyor means, said diverting means including means for preventing said superposed flat articles from becoming jammed together so that said tierlike superposed relationship between articles is maintained during said diverting movement.

Claim 3
Dependent Claim
105 words
The improvement according to claim 1, wherein said drive means comprises selectively actuatable first and second drive mechanisms, said first drive mechanism effecting a drive of said articles from said first conveyor means to said second conveyor means, said second drive mechanism effecting a drive of said articles from said first conveyor means to said third conveyor means; and including blocking means for rendering one of said first and second drive mechanisms ineffective to thereby effect a transfer by the other of said first and second drive means of said tierlike superposed flat articles onto a selected one of said second and third conveyor means.
Claim 4
Dependent Claim
18 words
The improvement according to claim 2, wherein said first and second drive mechanisms each comprise a roller mechanism.
Claim 5
Dependent Claim
43 words
The improvement according to claim 3, wherein said roller mechanisms each comprise a dividing roller and a pressure roller mounted above said dividing roller, and includes lift support means for supporting said pressure roller to be lifted from engagement with said dividing roller.
Claim 6
Dependent Claim
16 words
The improvement according to claim 4, wherein said pressure rollers are shorter than said dividing roller.
Claim 7
Dependent Claim
30 words
The improvement according to claim 3, wherein said rollers are arranged in a V-shaped arrangement, the diverging end of said V-shaped arrangement facing said end of said first conveyor means.
Claim 8
Dependent Claim
23 words
The improvement according to claim 6, wherein the end of each of said pressure rollers facing said first conveyor means is conically shaped.
Claim 9
Dependent Claim
39 words
The improvement according to claim 7, wherein said blocking means comprises a movable roller cover which is supported for movement between said superposed articles and one of said rollers to prevent said transfer of articles by said one roller.
Claim 10
Dependent Claim
34 words
The improvement according to claim 1, wherein said diverting means comprises a swordlike slide and drive means for inserting said slide between a pair of mutually adjacent articles exiting from said first conveyor means.
Claim 11
Dependent Claim
43 words
The improvement according to claim 9, wherein said slide includes support means for supporting said slide for a reciprocating movement, said slide including means defining a surface onto which said articles slide when said slide functions to divert the flow of said articles.
Claim 12
Dependent Claim
37 words
The improvement according to claim 10, including a pair of reciprocating slides each being adapted to engage said articles on a laterally spaced edge thereof to divert the movement of said articles from said first conveyor means.
Claim 13
Dependent Claim
20 words
The improvement according to claim 11, including means for supporting each of said slides for movement about parallel pivot axes.
Claim 14
Dependent Claim
20 words
The improvement according to claim 1, including a counting device for counting said articles conveyed by said first conveyor means.
