An energy harvesting roller for a cargo handling system may comprise a shaft and a sleeve located on the shaft. A piezoelectric member may be coupled to the sleeve. A shell may be located radially outward of the piezoelectric member and configured to rotate relative to the sleeve. A radially inward surface of the shell may define at least one of a plurality of grooves or a plurality of protrusions.

A method for automatically calibrating a rocker-type sensor module having a position or acceleration sensor involves measuring a position of the sensor module as an angle relative to a fixed spatial direction, and outputting an output signal that depends on whether the measured angle is less than or greater than a switching angle. The output signal is set to a first output value if the measured angle exceeds the switching angle. The switching angle is set to a value corresponding to the measured angle minus an “off” free pivot angle, as long as the value of the measured angle continues to increase. The output signal is set to a second output value if the measured angle falls below the switching angle. The switching angle is set to a value corresponding to the measured angle plus an “on” free pivot angle, as long as the value of the measured angle continues to fall.

Various embodiments illustrated herein disclose a container unloader device. 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.

A grouping station for grouping pallets includes an inbound conveyor, which is a gravity conveyor. The grouping station includes a fixed-height pairing conveyor and a grouping conveyor with three height positions for different grouping functions.

The present invention concerns an order-picking system, comprising a goods-in buffer (3) with at least one storage area (4), in which the picked goods units are stored before they leave the order-picking system, and at least one staging area (6), in which the picked goods units are staged automatically by an operating device in accordance with a predetermined sequence. In addition, the present invention comprise a pallet racking warehouse for a shipping buffer and a stacker crane for a corresponding pallet racking warehouse. A gravity conveyor (5) for the staging area of the shipping buffer is also the subject-matter of the present invention.

A sliding device configured to perform a sliding process on a surface of an object to be slid includes a sliding part including sliding bodies each having a flat working surface; a first driving mechanism configured to regularly move the sliding bodies in parallel with the working surfaces of the sliding bodies; and a second driving mechanism configured to regularly move the sliding part in parallel with the working surfaces in a direction different from a moving direction by the first driving mechanism while the first driving mechanism moves the sliding bodies. This enables uniform supply of the sliding process material onto the surface of the object to be slid or clean the surface of the object to be slid.

A rolling structure and a method of mounting the same on an object are introduced. The rolling structure includes a body portion, a first rolling member and at least one second rolling member. The body portion is disposed at an object. The first rolling member is movably disposed at the body portion and adapted to roll in the first direction. The second rolling member is movably disposed at the body portion and adapted to roll in the second direction. Therefore, the rolling structure is structurally simple, easy to use, and mechanically strong so as to cut cost.
