Abstract

This collator bin includes an upper sheet deflector associated with grounded metallic tinsel, such that the entering paper sheet is deflected downward, away from the tinsel. If the sheet carries an electrostatic charge, the air between the sheet and the tinsel ionizes, and the charge on the sheet is reduced.

Collator Bin

This collator bin includes an upper sheet deflector associated with grounded metallic tinsel, such that the entering paper sheet is deflected downward, away from the tinsel. If the sheet carries an electrostatic charge, the air between the sheet and the tinsel ionizes, and the charge on the sheet is reduced.

Sheet discharging, electrically conductive tinsel 10 is mounted on the top wall of each collator bin. This tinsel is mounted generally behind flap 11 so as not to physically engage the entering sheet. Flap 11 is nonconductive and flexible plastic. Its function is to hold down the trailing edge of sheet stack 12, to reduce the kinetic energy of the entering sheet, to squeeze the air out from under the entering sheet, and to prevent physical contact between the sheet and the tinsel
10.

The sheet's leading edge first encounters flap 11. The flap and the tinsel 10 extend the width of the bin, for example 15 inches. The flap 11 is, for example, 0.004 inch thick.

Tinsel 10 is constructed with sharp, needle-like points. The electrical field created between the charged sheet and these sharp points causes the air between the tinsel 10 and the sheet to ionize, thereby reducing the charge on the sheet's surface. Since the sheet does not physically engage the tinsel 10, tinsel wear is reduced. Thus, the tinsel's ability to create an electrical ionizing field, from the sharp points thereof, does not degrade with use.
