ABSTRACT:
A typical product overwrap machine includes a crossfeed conveyor, a pusher bar for transferring bread products to a lifting table which moves upwardly to wrap the bread product with a sealing wrap, and the wrapped bread product is sealed by heated rollers. The present invention provides a sensor and control systems operating servomotors or AC drives so that the crossfeed conveyor is operated only when product is detected at a conveyor inlet, and the pusher bar is actuated to move the product from the crossfeed conveyor when product is detected. The control systems detect the width of a pusher bar plate and adjust the separation of flight bars in the crossfeed conveyor to match the size of the installed pusher bar plate, thereby preventing damage to the crossfeed conveyor if there is a mismatch in sizes. Other control systems may be provided to adjust both the width of the pusher bar and the separation of flight bars in the crossfeed conveyor.
