Device for delivery of sorted elements for feeding a downstream work station that includes a downward drop that brings the elements, a one-at-a-time processor that receives the elements from the drop, an upward conveyor branch that extends from the processor and that receives the elements therefrom, and an ejector that is located in the area of the upward conveyor branch. The device includes at least one viewing unit that is positioned to monitor the elements in the area of the processor, such as a camera.

A sheet conveying device includes a supporting shaft, a rotating unit removable from an installation portion, a movable shaft, and an interlocking device. The rotating unit includes first and second ends, a holding member that holds a rotating body that conveys a sheet. The supporting shaft supports the rotating unit at the first end in an axial direction of the rotating body. The movable shaft is movable in the axial direction and supports the second end. The interlocking device moves the movable shaft per the rotating unit movement. Where the rotating unit is to be moved at a moving amount towards a side in which the rotating unit separates from the supporting shaft as part of removing the rotating unit from the installation portion, the interlocking device moves the movable shaft in the axial direction at a moving amount that is larger than the moving amount the rotating unit.

In a transporting system, a first conveyor includes a transport surface to transport different size tires in a first direction. A first positioner positions an end of a tire transported by the first conveyor, at a first predetermined position in the first direction. A second positioner positions an end of the tire at a second predetermined position in a second direction horizontally perpendicular or substantially perpendicular to the first direction. The first and second clamping portion portions are at or adjacent to a clamping position, and pass through between a tire first portion at or adjacent to an end of the tire positioned by the first positioner and a tire second portion at or adjacent to an end of the tire positioned by the second positioner to clamp side surfaces of the tire.

An embedding cassette marking machine and an operating method are provided. The embedding cassette marking machine includes: a housing; a feeding mechanism; a laser marking mechanism for marking the embedding cassette that slides down to the slideway assembly; and a discharging mechanism, which includes a pushing assembly and a material-carrying rail. The pushing assembly includes a pushing block, and the pushing block is configured to reciprocate toward or away from the material-carrying rail, so as to push the marked embedding cassette to the material-carrying rail.
