Abstract

Described herein are systems and methods providing a slip gear for an industrial cart. One embodiment includes a slip gear that includes a track gear for engaging with the track, a stabilizing bar, and a motor gear for engaging with a drive motor and the track gear. The slip gear may also include a stabilizing bar that is rotatably coupled to the track gear and the motor gear. In some embodiments, when the drive motor rotates the motor shaft, the motor gear rotates with the motor shaft to cause rotation of the track gear to propel the industrial cart. In response to an object pushing the industrial cart along the track, the stabilizing bar rotates to disengage the track gear from the track, thereby reducing friction between the industrial cart and the track.

First claim

What is claimed is:

1. An industrial cart, comprising:
a drive motor that facilitates propelling of the industrial cart along a track, wherein the drive motor includes a motor shaft; and
slip gear, wherein the slip gear comprises:
a track gear for engaging with the track;
a motor gear for engaging with the drive motor of the industrial cart and the track gear, wherein the motor gear is physically coupled to the track gear; and
a stabilizing bar that is rotatably coupled to the track gear and the motor gear,
wherein the stabilizing bar defines a motor pass through for receiving the motor shaft,
wherein when the drive motor rotates the motor shaft, the motor gear rotates with the motor shaft to cause rotation of the track gear to propel the industrial cart along the track, and
wherein in response to the drive motor ceasing rotation and an object contacting a rear surface of the industrial cart to push the industrial cart along the track, the stabilizing bar rotates to disengage the track gear from the track, thereby reducing friction between the industrial cart and the track.

2. The industrial cart of claim 1 , wherein the track includes a plurality of track teeth and wherein the track gear includes a plurality of track gear teeth, such that the plurality of track gear teeth engage with the plurality of track teeth to propel the industrial cart along the track.

3. The industrial cart of claim 1 , wherein the track is part of an assembly line grow pod and the industrial cart receives at least one of the following: a seed or a plant.

4. The industrial cart of claim 1 , further comprising a sensor to determine when the industrial cart is being is being pushed by the object.

5. The industrial cart of claim 1 , wherein the stabilizing bar rotates to disengage the track gear from the track via electrical power.

6. The industrial cart of claim 1 , wherein the stabilizing bar is freely rotatable respective to the motor gear, such that when the object pushes the industrial cart, the track gear is pushed by the track to automatically disengage from the track.

7. The industrial cart of claim 1 , wherein the object includes a trailing cart that is traveling behind the industrial cart on the track.

8. A system, comprising:
a drive motor that facilitates propelling of the an industrial cart along a track;
slip gear that is coupled to the drive motor, wherein the slip gear engages a gear of the track to enable the drive motor to propel the industrial cart, and
an assembly line grow pod that is configured to receive a plurality of industrial carts, wherein at least a portion of the plurality of industrial carts traverse the track to facilitate growth of plants,
wherein in response to a trailing cart contacting the industrial cart to propel the industrial cart along the track without use of the drive motor, the slip gear disengages from the track to allow the trailing cart to propel the industrial cart along the track.

9. The system of claim 8 , wherein the slip gear comprises a track gear, a motor gear, and a stabilizing bar, wherein the stabilizing bar is rotatably coupled to the track gear and the motor gear, wherein the track gear is coupled to the motor gear, wherein when rotation of the drive motor causes the motor gear to rotate, which causes the track gear to rotate, wherein when the track gear is engaged with the track, the rotation of the track gear causes traversal of the industrial cart along the track.

10. The system of claim 9 , wherein the track includes a plurality of track teeth and wherein the track gear includes a plurality of track gear teeth, such that the plurality of track gear teeth engage with the plurality of track teeth to propel the industrial cart along the track.

11. The system of claim 9 , wherein the stabilizing bar is freely rotatable respective to the motor gear, such that when the trailing cart pushes the industrial cart, the track gear is pushed by the track to automatically disengage from the track.

12. The system of claim 9 , wherein the stabilizing bar rotates to disengage the track gear from the track via electrical power.

13. The system of claim 8 , further comprising a sensor to determine at least one of the following: when the industrial cart is being is being pushed by the trailing cart, when the industrial cart has malfunctioned, or when the industrial cart is about to malfunction.

14. A slip gear for an industrial cart, comprising:
a track gear for engaging with a track;
a motor gear for engaging with a drive motor of the industrial cart and the track gear; and
a stabilizing bar that is coupled to the track gear and the motor gear, wherein the track gear is also coupled to the motor gear,
wherein the stabilizing bar defines a motor pass through for receiving a motor shaft of the drive motor,
wherein when the drive motor rotates the motor shaft, the motor gear rotates with the motor shaft to cause rotation of the track gear to propel the industrial cart along the track, and
wherein in response to the drive motor ceasing rotation and an object contacting a rear surface of the industrial cart to push the industrial cart along the track, the stabilizing bar rotates to disengage the track gear from the track, thereby reducing friction between the industrial cart and the track.

15. The slip gear of claim 14 , further comprising the drive motor.

16. The slip gear of claim 14 , wherein the track includes a plurality of track teeth and wherein the track gear includes a plurality of track gear teeth, such that the plurality of track gear teeth of the track gear engage with the plurality of track teeth to propel the industrial cart along the track.

17. The slip gear of claim 14 , wherein the track gear includes a plurality of track gear teeth and the motor gear includes a plurality of motor gear teeth, wherein the plurality of motor gear teeth engage with the plurality of track gear teeth to propel the industrial cart along the track.

18. The slip gear of claim 14 , wherein the track is part of an assembly line grow pod and the industrial cart receives at least one of the following: a seed or a plant.

19. The slip gear of claim 14 , wherein the stabilizing bar is freely rotatable respective to the motor gear, such that when the object pushes the industrial cart, the track gear is pushed by the track to automatically disengage from the track.
