Abstract

After a photoreceptor belt is ultrasonically welded, it is notched to remove weld splash that is created during the welding process. The notch chips sometimes adhere to the anvil by static. When the next photoreceptor belt is formed and welded, the notch chip left on the anvil is welded into the weld seam causing horn burn. Therefore, the photoreceptor belt is rejected as defective.

After a photoreceptor belt is ultrasonically welded, it is notched to remove weld splash that is created during the welding process. The notch chips sometimes adhere to the anvil by static. When the next photoreceptor belt is formed and welded, the notch chip left on the anvil is welded into the weld seam causing horn burn. Therefore, the photoreceptor belt is rejected as defective.

A vacuum style notcher block can prevent the above described problem. In particular, the notcher block incorporates both an air port and a vacuum port, which may be angled at about 300 degrees from each other. The air port is used to blow air at the notch chip to help lessen the static effect of the chip to the anvil. The vacuum port will then remove the notch chip from the anvil and dispense it into the vacuum system. The air port and the vacuum port can work simultaneously with each other. The vacuum notcher block can move up and down by the use of air cylinders. In addition, the timing hole punch can be incorporated into the vacuum line so that the timing hole chips can be removed from the finishing machine.
