Patent ID: 7269934

Claim:
An assembly for folding an insert for placement within the opening of a taco shell, nesting individual taco shells to form a nested group of taco shells, placing the insert within the nested group of taco shells, and aligning the nested group of taco shells comprising: a first apparatus for folding the insert for placement within the opening of a taco shell of the nested group of taco shells including: a frame; a first pivot shaft rotatably connected to the frame; a second pivot shaft rotatably connected to the frame; a first lever arm perpendicularly connected to the first pivot shaft; a second lever arm perpendicularly connected to the second pivot shaft; a first folder finger perpendicularly connected to the first pivot shaft and adapted to engage the insert; a second folder finger perpendicularly connected to the second pivot shaft and adapted to engage the insert; a spring having a first end and a second end, wherein the first end is connected to the first lever arm and the second end is connected to the second lever arm; and an insert magazine connected to the frame for holding the insert prior to delivery to the first and second folding fingers, the insert magazine comprising a channel and a slide block, the slide block having an angled leading face and adapted to slidably displace within the channel, the channel adapted to receive inserts; a second apparatus for nesting the individual taco shells to form the nested group of taco shells including: a nester conveyor adapted to transport taco shells to a taco shell nesting station and having a first operational speed and a second operational speed, wherein the first operational speed is greater than the second operational speed; and a first sensor adapted to detect the passage of taco shells traveling to the nesting station, wherein the nester conveyor shifts from the first operational speed to the second operational speed when the passage of a predetermine number of taco shells has been detected by the first sensor; a third apparatus for placing the insert within the nested group of taco shells including: a horizontal shaft; and a vacuum cup adapted to transport the insert and supported off of a first pillow block having a bore therethrough for receiving the horizontal shaft; and a fourth apparatus for aligning the nested group of taco shells including: a convergence volume adapted to hold the nested group of taco shells; a pair of opposed vertical surfaces forming two sides of the convergence volume and adapted to converge towards each other to align the nested group of taco shells; and a structure located above the convergence volume and adapted to limit the vertical travel of the nested group of taco shells as aligning occurs.
