Tray apparatus
A tray apparatus includes an elongated platform and a tray mechanism. The tray mechanism includes a plate disposed onto the platform and an arm assembly coupled to the plate and including a post and an arm. The post is coupled to the plate and extends upwardly therefrom. The arm is rotatably coupled to the post between a first position and a second position. The plate receives a box containing foodstuffs from a conveyance apparatus. The plate moves in a first direction when moving from a first state toward a second state. The arm is configured to contact the box and rotate from the first position toward the second position when the plate is moving in the first direction. The arm is configured to contact and move the box in a second direction opposite the first along the platform when the plate moves from the second state toward the first state.

the arm is configured to contact the box and rotate from the first position toward the second position when the plate is moving from the first state toward the second state, and
the arm is configured to contact and move the box in the second longitudinal direction along the platform when the plate moves from the second state toward the first state.
2. The tray apparatus of claim 1 , wherein the post includes a slot having a helical shape.
3. The tray apparatus of claim 2 , further comprising:
a bearing and a fastener at least partially disposed in the slot,
wherein the fastener extends through the bearing and attaches to the arm so that the bearing and the arm translates in the slot as the arm moves between the first and second positions.
4. The tray apparatus of claim 3 , wherein:
the arm assembly includes a cap attached to an end of the platform, and
the cap acts as a stop to prevent the bearing and the fastener from being removed from the slot.
5. The tray apparatus of claim 1 , wherein the arm extends:
perpendicular to the first longitudinal direction of the platform when in the first position, and
parallel to the first longitudinal direction of the platform when in the second position.
6. The tray apparatus of claim 1 , wherein the arm is permitted to rotate in a clockwise direction and prevented from rotating in a counter-clockwise direction.
7. The tray apparatus of claim 1 , wherein the arm is near or at a lower end of the post when in the first position and near or at an upper end of the post when in the second position.
8. The tray apparatus of claim 1 , further comprising:
an alignment mechanism attached to the platform,
wherein the alignment mechanism includes:
a guide plate configured to contact and move the box laterally when the plate is moving from the first state toward the second state, and
a stopping plate attached to the guide plate and configured to contact and prevent the box from moving further in the first longitudinal direction when the plate moves from the first state toward the second state.
9. The tray apparatus of claim 8 , wherein the guide plate and the platform cooperate to define a space that accommodates the arm assembly when the plate is moving between the first and second states.
10. The tray apparatus of claim 1 , further comprising:
a plurality of tabs integral with and extending outwardly from a lateral side of the platform,
wherein the plurality of tabs is configured to interface with the conveyance apparatus.
11. The tray apparatus of claim 10 , further comprising:
guide members attached to the plurality of tabs,
wherein each guide member inclines upwardly from a first end positioned at a distal end of a respective tab toward a second end positioned at a proximal end of the respective tab.
12. The tray apparatus of claim 1 , further comprising:
a ledge attached to the platform and configured to receive the box from the platform, and
a sensor associated with the ledge and configured to detect another box on the ledge,
wherein the plate of the tray mechanism is prevented from moving from the second state toward the first state when the sensor detects the another box on the ledge.
13. The tray apparatus of claim 12 , wherein the sensor is an optical sensor.
14. A tray apparatus comprising:
an elongated platform; and
a tray mechanism including:
a plate disposed onto the platform and configured to receive a box containing foodstuffs from a conveyance apparatus, wherein:
the plate is movable in a first longitudinal direction of the platform when moving from a first state toward a second state, and
the plate is also movable in a second longitudinal direction of the platform that is opposite the first longitudinal direction when moving from the second state toward the first state;
an alignment mechanism attached to the platform, wherein:
the alignment mechanism includes a guide plate and a stopping plate,
the guide plate is configured to move the box laterally relative to the platform when the plate moves from the first state toward the second state a first distance,
the stopping plate is attached to the guide plate, and
the stopping plate is configured to contact and prevent the box from moving further in the first longitudinal direction when the plate moves from the first state toward the second state a second distance;
a ledge attached to the platform and configured to receive the box from the platform; and
a sensor associated with the ledge and configured to detect an object on the ledge, wherein the plate of the tray mechanism is prevented from moving from the second state toward the first state when the sensor detects the object on the ledge.
15. The tray apparatus of claim 14 , wherein the guide plate and the platform cooperate to define a space that accommodates the plate when the plate moves between the first and second states.
16. The tray apparatus of claim 14 , wherein the sensor is an optical sensor.
17. The tray apparatus of claim 14 , wherein:
the tray mechanism further includes a sliding mechanism movable between a first position and a second position,
the plate is cantilevered to the sliding mechanism,
the plate is movable from the first state toward the second state when the sliding mechanism moves from the first position toward the second position, and
the plate is movable from the second state toward the first state when the sliding mechanism moves from the second position toward the first position.
18. The tray apparatus of claim 14 , wherein a bottom surface of the plate has a Teflon® coating.
19. The tray apparatus of claim 14 , further comprising:
a plurality of tabs integral with and extending outwardly from a lateral side of the platform,
