A manufacturing apparatus produces defined lengths of meat or other filling materials for taquitos, enchiladas, burritos, and other rolled, wrapped, or folded tortilla foods. This apparatus includes a small, upper, filling conveyor that operates in parallel with a large, lower, tortilla conveyor. Other components include an extruder, nozzle, cutter, and various sensors that produce output signals indicating tortilla and filling position. Encoders are also provided to represent position and/or movement of at least the upper conveyor. According to the sensor outputs, a controller regulates operation of the upper conveyor, extruder, and cutter to produce and then accurately deposit segments of filling material upon tortillas as they pass by upon the lower conveyor. As needed, the controller (1) advances, reversed, and/or stops the upper conveyor, (2) directs the pump to start/stop filling production, and (3) regulates the cutter to cut extruded filling material.

[ What is claimed is:] [1.]1. A method for producing and then accurately depositing segments of filling material upon tortillas in a system that includes:a lower conveyor;an upper conveyor and selectable-speed drive motor;a portioning assembly including a pump, an extruder nozzle, and machine-activated blade;object sensors including one or more tortilla sensors and one or more filling sensors;a controller coupled to the motor, pump, sensors, and blade; re the method is performed by the controller and comprises operations of:performing operations to create a filling segment of a desired size, comprising:responsive to signals from the tortilla sensor indicating arrival of a tortilla at a first designated site on the lower conveyor, starting the pump at a prescribed time thereafter;responsive to signals from the filling sensor indicating arrival of filling material from the extruder nozzle at a first designated site on the upper conveyor, waiting for a predetermined advancement of the upper conveyor and then activating the blade and stopping the pump to complete a filling segment;performing operations to accurately deposit the completed filling segment upon the arriving tortilla, comprising:responsive to signals from the tortilla sensor indicating arrival of a tortilla at a second designated site on the lower conveyor, starting to monitor position of the lower conveyor;responsive to signals from the filling sensor indicating arrival of the filling segment at a second designated site on the upper conveyor, utilizing the tortilla's monitored position to determine offset between the filling segment and the tortilla;calculating a correction profile of upper conveyor movement to place the filling segment in predetermined relationship to the tortilla; anddirecting the motor to execute the correction profile and deposit the filling segment upon the tortilla.
