CLAIMS

What is claimed is:

1. A multi-head fastening device comprising:

a chassis comprising;

a frame having a longitudinal and transverse axis:

a plurality of wheels secured to the frame;

a transverse rail movable relative to the frame;

a plurality of automated fastening heads mounted to the movable rail; each fastening head configured to automatically install a fastener to a substrate below the chassis and further configured to move vertically;

a fastener loading mechanism; and

a control system for activating the plurality of fastener heads.

2. The device of claim 1 further comprising a first servo motor for moving the transverse rail and a second servo motor for moving the plurality of fastening heads.

3. The device of claim 2 wherein the second servo motor comprises a plurality of servo motors.

4. The device of claim 1 wherein each of the plurality of fastening heads has dedicated servo motor and is configured to move independently from any other fastening head.

5. The device of claim 1 further configured with a plurality of servo motors to actuate movement of the transverse rail relative to the longitudinal axis of the frame and to actuate movement of each of the plurality of fastener heads vertically from a plane defined by the longitudinal and transverse axis of the frame.

6. The device of claim 1 further configured with an actuator to feed fasteners into each of the plurality of the fastener heads.

7. The device of claim 1 wherein the control system is configured to actuate two or more fastener heads simultaneously.

8. The device of claim 1 wherein the control system is configured to actuate two or more fastener heads independently.

9. The device of claim 1 wherein the control system is configured to actuate at least three fastener heads simultaneously in a first installation and to actuate at least two fastener heads in a second installation.

10. The device of claim 1 further comprising a photo sensor for determining the position of the plurality of fastener heads.

11. A system for installing multiple fasteners to a substrate comprising:

a chassis having a frame and a transverse member;

a plurality of fastener heads mounted to the transverse member;

a fastener feed system;

a fastener head actuator to move two or more fastener heads in simultaneous movement;

a control system comprising a processor configured to control movement of the fastener head actuator.

12. A method of installing multiple fasteners to a substrate comprising:

providing an multi-head fastening device comprising:

a frame having a longitudinal and transverse axis:

a plurality of wheels secured to the frame;

a transverse rail movable relative to the frame;

a plurality of automated fastening heads mounted to the movable rail; each fastening head configured to automatically install a fastener to a substrate below the chassis and further configured to move vertically;

a fastener loading mechanism; and

a control system for activating the plurality of fastener heads activating a first sequence wherein the control system causes a first set of the plurality of fastening heads to install multiple fasteners to a substrate at a first location, and

activating a second sequence wherein the control system causes a second set of the plurality of fastening heads to install multiple fasteners to a substrate at a second location.
