Abstract
Abstract There is disclosed an apparatus for aligning articles in parallel rows as the articles are being moved forward on a conveyor in a single row. A plurality of spaced apart dividers are provided for defining parallel lanes into which the articles are to be conveyed. A pivotally mounted guide chute is used for directing the articles into the respective parallel lanes. The guide chute can be readily exchanged for another guide chute by merely disconnecting various quick release mechanisms. A fixed frame member is carried above a conveyor which transports the articles and is used for supporting the guide chute. The guide chute includes a top plate which has a forward end that is pivotally mounted on the fixed frame member. A plurality of stops are carried on the top plate and are spaced apart a predetermined distance corresponding to the spacing between the various parallel lanes. Indexing mechanism is provided for indexing the guide chute between the various lanes. In order to control the flow of articles through the guide chutes to the throat of the lanes, pivotally mounted shoes are carried adjacent the outer end of the space rails forming the guide chute. These shoes, when in a first position, extend the length of the guide rail by means of planar side surfaces. When the shoes are shifted to a second position, a curved trailing surface provided on the shoes enter the path of travel of the articles between the rails, preventing the articles from passing between the rails.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
286 words
An apparatus for aligning articles in parallel rows and said articles are being moved forward on a conveyor in a single row, a plurality of spaced apart dividers defining a plurality of parallel lanes, said divides being positioned above said conveyor, a pivotally mounted guide chute having an inlet end and an outlet end, said outlet end of said guide chute being positioned adjacent said plurality of spaced apart dividers, a fixed frame member carried above said conveyor, said guide chute including: (a) a top plate having a forward end pivotally mounted on said fixed frame member; (b) a plurality of stops carried on said top plate and being spaced apart at predetermined distances corresponding to the spacings between said spaced apart dividers; (c) a main power operated cylinder for pivoting said outlet end of said guide chute about an arcuate pate to different positions; (d) said stops being located on an arcuate path corresponding to the arc of travel of the outer end of said guide chute; (e) an indexing means cooperating with said main power operated cylinder for indexing said outlet end of said guide chute from alignment with one lane to another lane; (f) said indexing means including a movable post; (g) said indexing means being carried by said fixed frame member with said post extending over said top plate so that said post engages and disengages a stop carried on said top plate as said post is moved between extended and retracted positions; and (h) means for selectively activating said indexing means to move said post to and from said extended and retracted positions when indexing said outer end of said guide chute from alignment with one lane to the next lane.
Claim 2
Independent Claim
286 words
An apparatus for aligning articles in parallel rows and said articles are being moved forward on a conveyor in a single row, a plurality of spaced apart dividers defining a plurality of parallel lanes, said divides being positioned above said conveyor, a pivotally mounted guide chute having an inlet end and an outlet end, said outlet end of said guide chute being positioned adjacent said plurality of spaced apart dividers, a fixed frame member carried above said conveyor, said guide chute including: (a) a top plate having a forward end pivotally mounted on said fixed frame member; (b) a plurality of stops carried on said top plate and being spaced apart at predetermined distances corresponding to the spacings between said spaced apart dividers; (c) a main power operated cylinder for pivoting said outlet end of said guide chute about an arcuate pate to different positions; (d) said stops being located on an arcuate path corresponding to the arc of travel of the outer end of said guide chute; (e) an indexing means cooperating with said main power operated cylinder for indexing said outlet end of said guide chute from alignment with one lane to another lane; (f) said indexing means including a movable post; (g) said indexing means being carried by said fixed frame member with said post extending over said top plate so that said post engages and disengages a stop carried on said top plate as said post is moved between extended and retracted positions; and (h) means for selectively activating said indexing means to move said post to and from said extended and retracted positions when indexing said outer end of said guide chute from alignment with one lane to the next lane.
Claim 3
Dependent Claim
149 words
The apparatus for aligning articles in parallel rows as set forth in claim 1 further comprising: (a) a quick release pivot connecting said forward end of said top plate to said fixed frame member; (b) a support plate carried by said fixed frame member adjacent a distal end of said top plate from said forward end; (c) a channel member carried by said top plate into which said support plate rides as said top plate and said guide chute are pivoted to different positions; (d) a quick disconnect member connecting said main power operated cylinder to said top plate, and (e) supporting frame members supporting said guide chute from said top plate; (f) whereby said top plate, supporting frame members and said guide chute can be readily removed from said fixed frame member so that a guide chute provided for accommodating a different size article can be substituted therefor.
