Abstract

An article inspection and orientation adjustment assembly is generally provided. The assembly is generally characterized by a primary subassembly operatively linked for travel with a secondary subassembly. The primary subassembly includes a vision system for visually inspecting conveyed articles, and an array of actuators, actuators thereof responsive to detections of the vision system and selectively energizable for conveyed article engagement in furtherance of altering an orientation of the conveyed article. The secondary subassembly includes a friction bar extending along a travel path for the conveyed articles, energization of an actuator of the array of actuators resulting in frictional engagement of an actuated article with the friction bar so as to rotatingly orient the actuated article.

Claims

1. An assembly for orienting conveyed articles comprising a primary subassembly operatively linked for travel with a secondary subassembly, said primary subassembly including a vision system and an array of actuators, actuators thereof responsive to detections of said vision system and selectively energizable for conveyed article engagement in furtherance of altering an orientation of the conveyed article, said secondary subassembly characterized by a friction bar extending along a travel path for the conveyed articles, energization of an actuator of said array of actuators resulting in frictional engagement of an actuated article with said friction bar so as to rotatingly orient the actuated article.

2. The assembly of claim 1 wherein said primary subassembly is directly driven for select reversible translation.

3. The assembly of claim 1 wherein said primary subassembly is directly driven for downstream synchronous translation with conveyed articles.

4. The assembly of claim 1 wherein said primary subassembly is directly driven for downstream synchronous translation with conveyed articles, and for upstream translation at a rate greater than downstream translation.

5. The assembly of claim 1 wherein said secondary subassembly is indirectly driven for select reversible translation.

6. The assembly of claim 1 wherein said primary subassembly is directly driven for select reversible translation and said secondary assembly is indirectly driven for select reversible translation, a rate of downstream translation for said secondary subassembly being less than a rate of downstream translation of said primary subassembly.

7. The assembly of claim 1 wherein said primary subassembly is directly driven for select reversible translation and said secondary assembly is indirectly driven for select reversible translation, a rate of downstream translation for said secondary subassembly being about one quarter to three quarters less than a rate of downstream translation of said primary subassembly.

8. The assembly of claim 1 wherein said primary subassembly is directly driven for select reversible translation and said secondary assembly is indirectly driven for select reversible translation, a rate of downstream translation for said secondary subassembly being about one half a rate of downstream translation of said primary subassembly.

9. The assembly of claim 1 further comprising a linkage for operatively uniting said primary subassembly with said secondary subassembly for combined travel of said subassemblies along the travel path for the conveyed articles.

10. The assembly of claim 1 further comprising a linkage for operatively uniting said primary subassembly with said secondary subassembly for combined travel of said subassemblies along the travel path for the conveyed articles, a rate of travel for said secondary subassembly being less than a rate of travel for said primary subassembly.

11. The assembly of claim 1 further comprising a linkage for operatively uniting said primary subassembly with said secondary subassembly for combined travel of said subassemblies along the travel path for the conveyed articles, a rate of travel for said secondary subassembly being about half of a rate of travel for said primary subassembly.

12. The assembly of claim 1 further comprising a linkage for operatively uniting said primary subassembly with said secondary subassembly, said linkage having a first end anchored to a portion of said primary subassembly, a portion of said secondary subassembly anchored to said linkage intermediate opposing ends thereof.

13. The assembly of claim 1 wherein said vision system comprises an optical device array.

14. The assembly of claim 1 wherein said vision system comprises an optical device array characterized by spaced apart groups of optical devices.

15. The assembly of claim 1 wherein said actuators comprise lifters for conveyed article tilting in furtherance of orientation adjustment via a tilted article engagement with said friction bar.

16. The assembly of claim 1 wherein said actuators comprise pneumatic cylinders for conveyed article tilting in furtherance of orientation adjustment via a tilted article engagement with said friction bar.

17. The assembly of claim 1 wherein each actuator of said actuators comprises an article engaging member characterized by a periphery comprised of a valley intermediate two peaks.

18. An assembly for orienting conveyed articles comprising a primary subassembly operatively linked for travel with a secondary subassembly, said primary subassembly including an operative combination of a lens and an image sensor, and an array of actuators, actuators thereof responsive to detections of said vision system and selectively energizable for conveyed article engagement in furtherance of altering an orientation of the conveyed article, said secondary subassembly characterized by a friction bar extending along a travel path for the conveyed articles, energization of an actuator of said array of actuators resulting in frictional engagement of an actuated article with said friction bar so as to rotatingly orient the actuated article.
