Abstract

This article describes a paper cutting mechanism for the continuous web feed customer receipt paper commonly employed in point of sale terminal printers and the like. The normal paper incrementing feed motor is employed through selective one-way clutches either to feed the paper or drive the cutter. The motor is a reversible type. This design eliminates the use of solenoid actuated guillotine blades and the like. These are sensitive to adjustment and have a low reliability as well as a significant electrical power consumption. A rotary drive motor is not subject to as many sensitive adjustments, has high reliability and uses relatively little electric power.

Rotary Shear Receipt Tape Cutter

This article describes a paper cutting mechanism for the continuous web feed customer receipt paper commonly employed in point of sale terminal printers and the like. The normal paper incrementing feed motor is employed through selective one-way clutches either to feed the paper or drive the cutter. The motor is a reversible type. This design eliminates the use of solenoid actuated guillotine blades and the like. These are sensitive to adjustment and have a low reliability as well as a significant electrical power consumption. A rotary drive motor is not subject to as many sensitive adjustments, has high reliability and uses relatively little electric power.

Figure 1 illustrates a cross-sectional end view of the mechanism shown in elevation in Figure 2. A rotating platen 1 is supported on a shaft 2 by one-way roller clutches 3. A rotating guillotine shear blade 4 is concentrically mounted on shaft 2 with platen 1 and is supported by a reverse oriented one-way clutch 5. A stationary blade 6 cooperates with the cutting edge of the rotating blade 4 to shear off a portion of paper 7 which is fed from a supply roll 8. A print head 9 is schematically shown in Figure 1 with the paper 7 between it and platen 1. A pressure roll 10 cooperates with the driving rotary platen 1 to withdraw paper from the supply roll 8, feed it past the print head 9 and deliver it past the stationary cutting blade 6 as shown in Figure 1.

In Figure 2, framework...
