1) Pallet flow rack
May be considered back-to-back selective rack. Inclined conveyor wheel sections are installed in the rack enabling back-loaded pallets are allowed to flow by gravity to the front or pick face. Pallet flow rack is useful for the movement of fast-moving items and serves to increase density of storage and throughput.
2) Platform conveyor
Another form of the conventional poternoster (See definition for Poternoster) is the platform conveyor that consists of multiple, equally spaced battens which form rigid horizontal surfaces in one direction (up and down) but behave like the front of a roll top desk on the return. Platform conveyor is an effective means of moving a continuous flow of pallets or other unit loads between levels.
Another variation of the posternoster concept, which permits both vertical and horizontal movement of load, consists of freely swinging platforms suspended between two parallel chains.
3) Pneumatic pusher
An air-powered conveyor sortation device. This device utilizes a ram and cylinder configuration and its movement is programmed to redirect packages and materials on a conveyor line.
4) Pnuematic puller
An air-powered conveyor sortation device. This device is used to redirect packages and materials on a conveyor. Pulling device travels beyond the object to be redirected and retracts, therein pulling the object in the desired direction.
5) Pop-up rollers
Rollers which rise up between chain or roller conveyors to move the item off the conveyor to the desired location.
6) Pop-up skewed wheel sorter
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 type of vertical conveyor that provides for continuous operation of multiple, equally spaced, load-carrying units fixed to chains that move continuously in an endless loop. With such a system the loading and unloading, usually automatic, occurs while the conveyor is running, resulting in greater throughput and an even flow of loads. This type of vertical conveyor is common in Europe
8) Power and free conveyor
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.
9) Powered conveyor
Conveyor of any type that's movement is driven by motors and drives. Power may be electrical or pneumatic.
10) Powered wheel diverter
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.
11) Push driver
A computer-controlled arm that can push items at a right angle from a conveyor line to the desired location.
12) Rake puller
A device in which tines pop up between conveyor rollers and pull the item accross the conveyor to the desired location.
13) Roller belt conveyor
A powered form of conveyor where the transporting belt is supported by rollers spaced along the frame, not unlike a gravity roller section. Power and forward motion is transferred by utilizing a moving belt powered by a pulley and motor configuration at one end of the section. Capable of handling rather heavy loads.
14) Roller conveyor
A series of roller supported in a frame over which objects are advanced manually, by gravity, or by power.
15) Roller diverter
A device on a conveyor sortation system used to move a case/carton/piece off the main line. This device utilizes "pop-up" type rollers to redirect the object in a predetermined direction.
