6. The tote exchange module of claim 4 , further comprising an exchange equipment configured to pick-up the tote located at the pick-up location responsive to processing of data captured by the one or more photoeyes indicating at least one of the presence or the predefined orientation of the tote satisfies a threshold requirement.

7. The tote exchange module of claim 6 , wherein the exchange equipment moves the tote from the pick-up location to a tote receiving position corresponding to a second conveyor.

8. A tote exchange module comprising:

a first conveyor comprising a forward end, an opposite trailing end, a first side and a second side approximately parallel to a transport direction of the first conveyor, and a conveyance system positioned between the first side and the second side and configured to transport one or more totes along the conveyance system in the transport direction, the transport direction of the first conveyor being in the direction from the trailing end toward the forward end, the second side comprising a wall;

an L-shaped pushing member comprising:

a forward element, the forward element comprising a forward surface orientated transverse to the transport direction and having a first forward surface end and a second forward surface end, and

a side element, the side element comprising a side surface oriented approximately parallel to the transport direction and having a forward side surface end and a trailing side surface end,

wherein (a) the forward element is secured to the side element at the first forward surface end of the forward surface and the forward side surface end of the side surface, (b) the forward side surface end of the side surface is closer to the forward end than the trailing side surface end, and (c) the second forward surface end is closer to the second side than the first forward surface end,

an actuator configured to move the L-shaped pushing member from a first position proximate to the first side to a second position proximate to the wall to cause a tote to move into a predefined orientation at the second position, and wherein the wall is configured to receive the tote in the predefined orientation at the second position, the second position defining a pick-up location;

a second conveyor;

a tote receiving position proximate to the second conveyor; and

a tote release system configured to move the tote located at the tote receiving position onto the second conveyor.

9. The tote exchange module of claim 8 , further comprising an exchange equipment configured to pick-up the tote located at the pick-up location and place the tote at the tote receiving position.

10. The tote exchange module of claim 8 , wherein the tote release system is configured to move the tote in a second transport direction, opposite to the transport direction of the first conveyor, towards the second conveyor.

11. The tote exchange module of claim 8 , wherein the tote release system is located adjacent to the second side of the first conveyor.

12. The tote exchange module of claim 9 , wherein the exchange equipment is configured to pick-up empty totes from the first conveyor and place filled totes on the tote release system.

13. The tote exchange module of claim 1 , further comprising a tote release system configured to move the tote located at a tote receiving position onto a second conveyor, wherein the tote release system comprises a plurality of timing belts that are driven together via a set of timing pulleys clamped to a motorized drive roller, wherein at least one of the plurality of timing belts comprises one or more cleats configured to receive and align the tote on the at least one of the plurality of timing belts, and wherein the one or more cleats further comprise one or more proximity sensor targets configured to detect the presence of the tote on the at least one of the plurality of timing belts.

14. The tote exchange module of claim 13 , wherein the tote release system is further configured to move the tote in a second transport direction, opposite to the transport direction of the conveyor, towards the second conveyor from the tote receiving position.

15. The tote exchange module of claim 13 , wherein the tote release system is further configured to receive the tote from an exchange equipment in a tote release position.

16. The tote exchange module of claim 13 , further comprising one or more photoeyes configured to confirm the presence of the tote on an exchange equipment, and wherein the plurality of timing belts are configured to move the one or more cleats in a receiving position responsive to processing of data captured by the one or more photoeyes indicating the presence of the tote on the exchange equipment.
