An apparatus for conveying and arranging bakery products such as hot dog buns or breadsticks. The products are delivered with their length dimensions at a variety of angular orientations and some products inverted. An aligning conveyor receives misaligned products on adjacent belts or other drive members which are driven at differential speeds to rotate the products to the proper orientation. Inverted products are conveyed against guide rails which are arranged to interact with the curved edges on the tops of the buns to roll the inverted products over. The products are conveyed in discrete lanes to properly organize them for packaging.

1. An aligning conveyor operable for conveying and aligning first bakery products each having a width dimension and a length dimension greater than said width dimension, said aligning conveyer comprising: a conveyor mechanism operable to convey said first bakery products in a conveying direction along a conveying surface;a plurality of guides spaced apart to provide a plurality of substantially parallel lanes extending in said conveying direction and sufficiently wide to receive said first bakery products with said length dimensions oriented generally in the direction of said conveying direction, said guides each having an upper edge portion; anda drive element on the upper edge portion of each guide mounted thereon for movement generally parallel to said conveying direction and operable at different speeds to allow aligning of said length dimension;wherein said guides are movable generally up and down between an extended position wherein said guides project above said conveyor surface to provide said lanes and a retracted position wherein all said guides can be retracted below said conveyor surface to allow conveying of bakery products that do not have a length dimension greater than the corresponding with direction. 2. Aligning conveyor as set forth in claim 1, wherein said drive elements comprise drive belts traveling on said upper edge portions of said guides. 3. Aligning conveyor as set forth in claim 1, said drive elements being driven in the same direction at different speeds to turn misaligned first bakery products delivered to said aligning conveyor with the length dimensions thereof offset substantially from said conveying direction, thereby turning such misaligned first bakery products to allow dropping thereof between said guides. 4. Aligning conveyor as set forth in claim 3, wherein each said drive element is driven at a speed that is either slower or faster than the speed of an immediately adjacent drive element. 5. Aligning conveyor as set forth in claim 1, further comprising a carriage to which said guides are mounted, said carrier being operable for moving said guides between said extended position and said retracted position. 6. Aligning conveyor as set forth in claim 1, operable for conveying second bakery products having a width dimension and a length dimension substantially equal to said width dimension when said guides are in said retracted position. 7. Aligning conveyor as set forth in claim 6, wherein said first bakery products are hot dog buns, bread sticks or other products having a length dimension greater than a width dimension and said second bakery products are hamburger buns, rolls or other products that do not require a particular orientation. 8. Aligning conveyor as set forth in claim 1, wherein top surfaces of all said drive elements are in a common first plane when said guides are in said extended position and in a common second plane when said guides are in said retracted position. 9. Aligning conveyor as set forth in claim 1, wherein the retraction of all said guides results in a conveyer surface having substantially no obstructions.
