As an intelligent track guidance handling equipment in automated storage system, the shuttle vehicle can display the high speed and high efficiency automatic conveying of the unit material, which has high automation and flexibility. The shuttle vehicle has the function of dynamically moving along the fixed path, which can realize the transmission between different stations, which makes the equipment layout of the automatic conveying system more compact and simple, improves the efficiency of material conveying, and is widely used in the automatic logistics system. The shuttle Shelf is one of the typical representatives of its use.

From the form of the track, the shuttle can be divided into reciprocating straight shuttle car, circular shuttle car, circular shuttle car can be run in the same track more than one body, is the development trend of the shuttle vehicle. Shuttle car and fixed at the end of the vertical elevator, continuous hoist or basket-type shelves free combination, with the use of Multi-layer shuttle, it is possible to replace the stacking machine, the completion of the rapid access to the box material operations. Due to the small ratio of the working payload to the equipment, it means that the energy consumption of each storage unit is greatly reduced, and the concept of green energy saving is in line with the current trend of world development.

Reciprocating straight-line shuttle vehicle is an intelligent track guidance handling equipment used in the automated logistics system, under the control of the electronic control system, we can accurately locate the input and output stations through the encoder, laser ranging and so on, and accept the material to carry out reciprocating shuttle transportation, which is mainly used in the unit logistics high speed in the automated logistics system. Efficient plane automatic transmission, with a high degree of automation and flexibility.

Reciprocating straight-line shuttle car mainly by the body system, conveying devices, access devices, rail systems, safety protection devices, electrical devices and shuttle vehicle scheduling management.

(1) Body system. Mainly by the frame body, walking drive device, decorative hood composition. The frame body is the main body which carries the other parts, and the main part is welded by the steel. The walking drive device consists of a drive shaft, a driving wheel and a motor. Walking Wheel of the driving device uses High-tech polyurethane material, not only improve the wear resistance of the wheel, but also greatly reduce the wheel and the friction wheel, which can prolong the service life of the wheel. In addition, the car body can be designed in accordance with the overall process flow needs of dual-body to meet the needs of dual-station.

(2) Conveying device. The conveying device is the conveying part of the material, which is installed on the body and the frame is made of steel structure. According to the form of materials, can choose roller conveyor, chain conveyor, belt conveyor and other transport forms, at the same time according to the overall process flow needs to design a dual conveyor to meet the demand for dual-station transportation, can greatly improve the delivery capacity.

(3) the address device. The identification device is the positioning signal device of the shuttle vehicle out of the storage platform. The device has a chain-type, synchronous belt type, friction wheel-type coding, and laser address, bar code identification and other ways, according to different modes of electronic control. The accuracy of the locating device can directly affect the positioning accuracy and the smoothness of the ship speed vehicle, so we should choose different way of address according to the operation ability and the investment cost of the equipment.

(4) guideway system. The guide rail system consists of a guide rail and a stop device, which is the guide for carrying the foundation and walking of the shuttle vehicle. Rail has purchased light rail, professional aluminum-type guide rail two forms. Both guides are equipped with a stop device, including a bumper and bracket, mounted on both ends of the track to prevent the shuttle from rushing out of the track in the event of an accident. The track type is selected according to the operation Capability requirement and the investment cost of the equipment.

(5) Safety protection device of shuttle car. The shuttle vehicle is equipped with a safe distance detection device and an obstacle detector, if detected in the range of its settings will emit sound and light alarm until it stops running, the safety protection device can not affect the normal operation of the shuttle, the effective protection of workers, goods in the shuttle car into the area of safety, and effectively prevent the shuttle vehicle itself damage.
