Abstract

A method and a system for dispensing bolts are provided. The system includes a dispensing cartridge including a dispensing tube and a dispensing section. The dispensing tube includes a first end, a second end, and a passage provided between the first end and the second end. The passage is configured to store a plurality of bolts to be supplied to the dispensing tube through the first end such that the bolts are moved through the passage. The dispensing section is located near the second end of the dispensing tube and is configured to dispense the bolts one at a time from the second end.

First claim

What is claimed is:

1. A method of dispensing bolts into apertures formed on a work piece, the method including steps of:
providing a dispensing cartridge including a gripping section, a dispensing tube, and a dispensing section, the dispensing section configured to control opening and closing of an end of the dispensing tube, wherein the gripping section is configured to be engaged with or grasped by a first portion on a dock, or engaged with or grasped by a second portion on a robotic arm;
filling the dispensing tube with a plurality of bolts by stacking the bolts on top of one another; and
dispensing the bolts one at a time from the dispensing tube into apertures formed on a work piece using the dispensing section while the gripping section is engaged with or grasped by the second portion.

2. The method of claim 1 , wherein the bolts inside the dispensing tube are not of equal length.

3. The method of claim 1 , further including a step of transporting the dispensing cartridge, using the robotic arm, between
a bolt loading station where the step of filling the dispensing tube occurs, and
a holding device where the step of dispensing the bolts occurs, wherein the work piece is secured to the holding device.

4. The method of claim 3 , wherein the bolts are stacked inside the dispensing tube according to an order of apertures by which the robotic arm is configured to transport the dispensing cartridge.

5. The method of claim 4 , further including the step of emptying the dispensing cartridge in case the bolts are stacked in an incorrect order.

6. The method of claim 1 , further including a step of fastening the bolts to the apertures.

7. The method of claim 1 , wherein the bolts are dispensed into the apertures by way of gravity.

8. A method of dispensing bolts into apertures formed on a work piece, the method including steps of:
providing a first dispensing cartridge and a second dispensing cartridge, each of the first dispensing cartridge and the second dispensing cartridge including a
dispensing tube, a gripping section, and a dispensing section, wherein the dispensing section is configured to control opening and closing of an end of the dispensing tube;
filling the dispensing tube of the first dispensing cartridge with bolts;
filling the dispensing tube of the second dispensing cartridge with bolts; selecting the first dispensing cartridge using a robot; and
using the robot for dispensing the bolts one at a time from the end of the dispensing tube of the first dispensing cartridge into apertures formed on a work piece using the dispensing section of the first dispensing cartridge.

9. The method of claim 8 , wherein the step of dispensing the first dispensing cartridge and the step of filling the dispensing tube of the second dispensing cartridge occur at least in part simultaneously.

10. The method of claim 8 , wherein the bolts in the first dispensing cartridge are different in diameter from the bolts in the second dispensing cartridge.

11. The method of claim 8 , further comprising the steps of:
selecting the second dispensing cartridge using the robot; and
dispensing the bolts one at a time from the end of the dispensing tube of the second
dispensing cartridge into apertures formed on the work piece or another work piece using the dispensing section of the second dispensing cartridge.

12. The method of claim 1 , wherein the dispensing tube is filled with said plurality of bolts when the gripping section is engaged with or grasped by the first portion; and
the bolts are dispensed one at a time from the dispensing tube into the apertures formed in the work piece when the gripping section is engaged with or grasped by the second portion.

13. The method of claim 1 , wherein the dispensing tube is filled with said plurality of bolts when the gripping section is engaged with or grasped by the first portion.

14. The method of claim 8 , wherein the gripping section is configured to be engaged with or grasped by the robot, wherein selecting the first dispensing cartridge using the robot further comprises:
grasping or engaging the gripping section of the first dispensing cartridge with a first portion of the robot.

15. The method of claim 14 , wherein filling the dispensing tube of the first and second dispensing cartridge with bolts further comprises:
grasping or engaging the gripping section of the first dispensing cartridge and the second dispensing cartridge with a portion of a dock.
