The container unloader device comprises a platform to receive a container, wherein the container comprises a package. The container unloader device also comprises a front panel configured to move between a raised orientation and a lowered orientation, wherein when the front panel being is in the raised orientation, the front panel is orthogonal with respect to the platform, and when the front panel is in the lowered orientation, the front panel and the platform form a continuous surface. The platform can be pivoted from a first angle to a second angle, that is greater than the first angle. The package leans against the front panel the front panel is in the raised orientation. The package is released on a surface of a conveyor when the front panel is in the lowered orientation. ## Claims ### Claim 1 A method comprising: receiving a container on a platform of a device, wherein the container comprises an item and wherein the platform is at a first angle with respect to a ground surface when the platform receives the container; moving a front panel of the device between a raised orientation and a lowered orientation with respect to the platform, wherein in response to the front panel being in the raised orientation, the front panel is orthogonal with respect to the platform, and in response to the front panel being in the lowered orientation, the front panel and the platform form a continuous surface; pivoting the platform from the first angle to a second angle with respect to the ground surface that is larger than the first angle, wherein pivoting the platform to the second angle comprises at least one or more of: rotating the container around a rotational axis which is normal with respect to the platform to configure the item in the container to lean against a surface of the front panel when the front panel is in the raised orientation; and rotating the container around the rotational axis which is normal with respect to the platform to configure the item to be released onto a surface of a conveyor when the front panel is in the lowered orientation; and wherein the method further comprises configuring a rotary joint to be placed between the platform of the device and the container to rotate the container around the rotational axis which is normal with respect to the platform. ### Claim 2 (depends on 1) The method of claim 1, wherein the method further comprises configuring a first side panel and a second side panel of the front panel of the device to be placed in an upright position with respect to a surface of the front panel. ### Claim 3 (depends on 1) The method of claim 1, wherein the method further comprises configuring a roller bed to receive the container, wherein the roller bed is positioned on the platform of the device. ### Claim 4 (depends on 1) The method of claim 1, wherein the method further comprises latching the container to a surface of the platform of the device using a locking mechanism. ### Claim 5 (depends on 4) The method of claim 4, wherein the locking mechanism further comprises one or more latches. ### Claim 6 (depends on 1) The method of claim 1, wherein the method further comprises transporting the container to the device using at least one of a robotic device or a fork-lift truck. ### Claim 7 (depends on 6) The method of claim 6, wherein the method further comprises transferring the container from at least one of the robotic device or the fork-lift truck to the platform of the device. ### Claim 8 (depends on 6) The method of claim 6, wherein the method further comprises configuring the container to be transported from the platform of the device to at least one of the robotic device or the fork-lift truck when the item has been released on the surface of the conveyor.
