Abstract

A dispensing device includes a drive unit, a detector and a controller. The drive unit is configured to operate a material dispenser. The detector is configured to detect a velocity of the material sensor. The controller is programmed to maintain the material dispenser at a constant velocity based on the velocity detected by the detector.

First claim

What is claimed is:

1. A dispensing device comprising:
a drive unit configured to operate a material dispenser;
a detector configured to detect a velocity of the material dispenser; and
a controller configured to maintain the material dispenser at a constant velocity based on the velocity detected by the detector, and to terminate voltage supplied to the drive unit, when the detector detects that the velocity is less than a predetermined velocity.

2. The dispensing device of claim 1 , wherein
the material dispenser is a plunger.

3. The dispensing device of claim 1 , wherein
the material dispenser is a first material dispenser of a plurality of material dispensers, and
the drive unit is configured to operate the plurality of material dispensers.

4. The dispensing device of claim 1 , wherein
the dispensing device is configured to mix first and second materials.

5. The dispensing device of claim 1 , further comprising
a power supply configured to provide a voltage to the drive unit to operate the material dispenser, and
the controller being configured to monitor at least one of a current provided to the drive unit and the speed of the material dispenser, and increase at least one of the current from an initial current to a target current and an initial speed to a target speed over a predetermined time interval.

6. The dispensing device of claim 5 , wherein
the controller is configured to increase the speed of the material dispenser to the target speed by increasing the speed of the material dispenser at intervals of 0.1 seconds for 3 seconds.

7. The dispensing device of claim 5 , wherein
the controller is configured to increase the current provided to the drive unit to the target current by increasing the current of the material dispenser at intervals of 0.1 seconds for 5 seconds.

8. The dispensing device of claim 5 , wherein
the target speed is between 0.5 and 5 mm/s.

9. The dispensing device of claim 5 , wherein
the material dispenser is a plunger.

10. The dispensing device of claim 5 , wherein
the material dispenser is a first material dispenser of a plurality of material dispensers, and
the drive unit is configured to operate the plurality of material dispensers.

11. The dispensing device of claim 5 , wherein
the dispensing device is configured to mix first and second materials.

12. A dispensing device comprising:
a drive unit configured to operate a material dispenser;
a power supply configured to provide a voltage to the drive unit to operate the material dispenser; and
a controller configured to monitor a current provided to the drive unit based on the voltage, adjust the voltage to a voltage level that maintains the current at or below a predetermined threshold, and modify a pulse length of the voltage based on a change in the voltage of the power supply.

13. The dispensing device of claim 12 , wherein
the material dispenser is a plunger.

14. The dispensing device of claim 12 , wherein
the material dispenser is a first material dispenser of a plurality of material dispensers, and
the drive unit is configured to operate the plurality of material dispensers.

15. The dispensing device of claim 12 , wherein
the dispensing device is configured to mix first and second materials.
