A device on a conveyor sortation system used to move a case/carton/piece off the main line. The device utilizes wheels(skate) that are powered to raise up form the conveyor bed and divert the objects in the desired direction.
An in-line diverter conveyor that has wheels that pop up between the rollers of a powered roller conveyor or between belt conveyor segments and direct sorted items onto a powered take-away line. Fairly high speed sorting, in the range of 120 cases per minute, can be achieved.
A variation of overhead chain conveyor is "power and free". In a conventional overhead conveyor the carrier is permanently fastened to the drive chain, in the power and free case the carrier can mechanically disengage from the drive chain and essentially idle while the chain continues to move. Power and free conveyors can also be inverted so that they can be mounted to the floor, in which case the carrier or tray rides on top of the guiding rail as opposed to being suspended beneath it.
Palletizers are special machines capable of building a complete unit load on a pallet. Although the most common application is for cases, some palletizers can also handle sacks and bags. A less common palletizer application would be for special products such as sheet stock. There are two general methods employed for automatically building a full pallet. One makes use of a fixed position or overhead gantry robot with end effectors suited to the individual loads, such as vacuum lifts or a gripper. The other method employs more complex mechanisms for forming pallet layers off line, one at a time, and then shifting or transferring each successive layer onto the pallet as it is lowered via a lift/lower table.
Industrial trucks equipped with a telescoping fork arrangement that permits the stacking of loads double deep. For storage depths greater than two, there is at least one example in Europe where the fork unit mechanically disengages from the mast allowing it to run into the rack on narrow rails under its own power which is derived from the truck via an umbilical cord. Applications like this can be considered a very special case of a drive-in type storage rack.
A rotary rack is a special variation of a horizontal carousel. In this case each vertical level or storage location is mechanically independent of the location above or beneath it. Each level in turn is driven by a separate and independent drive. Therefore, simultaneous, independent rotation of each level is possible (in any direction). Although replenishment and picking can be accomplished manually, most rotary racks incorporate automatic load inserters and extractors. See also Horizontal Carousels and/or AS/RS .
