A pallet centering device includes a frame upon which is mounted a plurality of conveyor rollers, the conveyor rollers mounted transverse to a direction of pallet travel. A first pallet pusher unit and a second pallet pusher unit are associated with respective sides of the support frame, both for reciprocal movement transverse to the direction of pallet travel. The first and second pallet pusher units each have pallet pusher members configured for engaging respective sides of a pallet. At least one transverse U-channel rail is mounted to the support frame beneath the conveyor rollers and defining a channel track. Each first and second pallet pusher unit has at least one depending bearing mount aligned with the channel track and provided with a bearing rotatably engaging the channel track. A drive assembly moves the first and second pallet pusher units reciprocally for centering the pallet located on the conveyor rollers.

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 conveying and metering device with an endless apron belt that is movable by rollers on guide rails, wherein sections of the guide rail that are opposite one another are separated from the adjacent sections and, for determining the mass of the conveyed material, are supported on weighing devices that are connected to an electronic analysis device. Provision is made that the sections of the guide rail to be weighed, together with longitudinal members and transverse struts that are perpendicular to the longitudinal members, form a weighing frame, and this weighing frame is supported at each of its four corners on a separate weighing device, wherein an adjustable centering device is provided between the weighing frame and each of the weighing devices.

A transport conveyor includes an upstream conveyor section, a downstream conveyor section, and a relay conveyor section having an orientation changeable between a connecting orientation, in which the relay conveyor section in a gap region to connect the upstream conveyor section to the downstream conveyor section, and an open orientation, in which the relay conveyor section is in a non-overlapping region that does not overlap a movement path to open the gap region. A support axis is above a drive axis, and a link mechanism is configured such that when the relay conveyor section is in the connecting orientation, a first pivot axis is below a reference virtual plane connecting the drive axis to a second pivot axis.

A trolley system for transferring cargo in relation to a cargo compartment of a vehicle includes a frame defining a cargo-retaining platform. The cargo-retaining platform is configured to receive and retain the cargo. At least a portion of a lower surface of the frame is formed of a low friction material. One or more handles are moveably coupled to the frame. The handle(s) are configured to be moved between a retracted position and an extended position. One or more attachments are configured to secure the cargo on the cargo-retaining platform.

A roller track includes a base, parallel guides, roller support bars placed into their respective guides, and a plurality of rollers removably disposed between the roller support bars. The roller support bars preferably are removably secured to the base via the respective guides which are affixed to the base. The base also can be provided with connecting elements sidewalls thereof such that a plurality of bases of roller tracks can be connected laterally to accommodate any width of shelf or display planogram. Thus, the roller tracks can be used either separately roller tracks or as a continuous mat (i.e. a plurality of roller tracks affixed to adjacent roller tracks). Additionally, dividers can be removably affixed to each roller track via securing members comprising an upper body portion formed via a living hinge and at least one lower connector that removably connects the securing member to the roller track.

In one aspect, a gap blocker having a body with an upper blocking portion and leg portions of the body connected to the upper blocking portion at longitudinally spaced apart locations. The leg portions of the body have an initial, undeflected configuration with at least one of the leg portions having a first orientation relative to the upper blocking portion. The leg portions of the body have an operating configuration with the body in a gap between rollers wherein the at least one of the leg portions has the first orientation relative to the upper blocking portion. The upper blocking portion has upper contact portions and the leg portions have lower contact portions for contacting the rollers. The body also has outer surface portions intermediate the upper and lower contact portions configured to be in clearance with the rollers.
