DETAILED DESCRIPTION OF EMBODIMENTS

Referring, to FIG. 1, a forklift 1 made in accordance with the present invention includes a hoisting apparatus 22, a fork 3 and a static electricity eliminating device 23. The static electricity eliminating device 23 can be readily moved vertically by the operation of the hoisting apparatus 22. The static electricity eliminating, device 23 can provide pressurized ionized airflow to an area above the fork 3.

Substantially, in the present embodiment, the hoisting apparatus 22 includes a pair of hoisting systems 22a, 22b. The static electricity eliminating device 23 is mounted in a sideway, and includes a pair of static electricity eliminating device 23a, 23b which is mounted to each of the hoisting systems 22a, 72b.

The forklift 1 further includes a pair of pillars 11, a swinging mechanism 12, a telescopic mechanism 13, a platform 14, and a moving mechanism 15. Each of the hoisting system 22a, 22b is mounted to a corresponding pillars 11. The platform 14 is interconnected to the hoisting system 22a, 22b with its sides. The swinging system 12 is disposed on a central area of the platform 14, and is further interconnected to the telescopic mechanism 13. The telescopic mechanism 13 is further interconnected with a fork 3.

With the operation of the hoisting apparatus 22, the hoisting systems 22a, 22b will drive the platform 14, the swinging mechanism 12, the telescopic mechanism 13, the fork 3 and the static electricity eliminating unit 23a to move synchronically along the vertical direction. By maneuvering the telescopic mechanism 13 and the swinging mechanism 12, the fork 3 can be completely retrieved within the platform 14, or extend beyond the platform 14. The moving mechanism 15 is disposed under the pillars 11 so as to move the forklift 1 along a preset direction. By way of the above description, the forklift 1 can readily used to dispose or retrieve an object located on different levels along a preset line.

In the present embodiment, the static electricity includes a pair of static electricity eliminating units 23a. However, the quantity of the static electricity eliminating unit 23 can be one or more than one or any suitable number. On the other hand, the static electricity eliminating device 23 can be mounted onto other location of the forklift 1. For example, the static electricity eliminating unit can be mounted onto a location on the platform 14 adjacent to the hoisting apparatus 22 so as to supply pressurized ionized airflow toward an area above the fork 3. Additional, it can also be mounted onto a top of the forklift 1 and from there to deliver the pressurized ionized airflow to the fork 3.

Referring now to FIGS. 2 and 3, the static electricity eliminating unit 23a further includes a rotating shaft 231, a transmitting mechanism 232, a stand 233, a blower 235, an air duct 236, a plurality of discharging probes 237, a fixture 238, and a dust hood 239.

The discharging probes 237 are arranged vertically and spaced from each other. The air duct 236 includes a basic duct (not shown) and a plurality of nozzle (not shown). The air duct is arranged vertically, and the nozzle is properly aligned with the discharging probe 237. The blower 235 will supply the pressurized airflow toward the discharging probe 237, and the discharging probe 237 will release ions into the pressurized airflow which is therefore filled with ions. Since the nozzle is vertically arranged with the duct, accordingly, the pressurized ionized airflow flows horizontally.

The fixture 233 is used to attach the static electricity eliminating unit 23a to the hoisting system 22a or 22b. The rotating shaft 231 is arranged vertically. The driving mechanism 232 drives the rotating shaft 231 to swing within a preset angle such that the static electricity eliminating unit will rotate with respect to the hoisting system. The rotational direction the static electricity eliminating systems 23a, 23b are opposite to each other. On the other hand, during the operation, the pressurized ionized airflow is directed toward an area above the fork 3 of the platform 14. As a result, the overage of the pressurized ionized airflow can readily and effectively eliminate accumulated static electricity loaded onto the fork, such as the cartridge filled with glass panels. Accordingly, the accumulated static electricity can he effectively eliminated so as to achieve the optimal result.

In the current embodiment, the transmitting mechanism 232 includes a servo motor (not shown) mounted onto the stand, and an output shaft (not shown) interconnected to the servo, and a belt connected to the rotating shaft 231.

The fixture 238 is used to securely attach the air duct 236 and the discharging probe 237. The rotating shaft 231, the blower 235, the air duct 236, and the discharging probe 237 are all installed within the dust hood 239.

As compared to the prior art, the forklift 1 of the present invention includes a static electricity eliminating device 23 driven by the hoisting apparatus 22. The static electricity eliminating device 23 discharges pressurized airflow with ions to an area above the fork 3 so as to drain and ground the static electricity accumulated on the object loaded onto the forklift 1. By ways of this, the static electricity within the automated warehouse can he effectively eliminated and controlled.

Referring to FIG. 4, the present invention farther provides a warehouse system which includes a forklift 1 and a storing tower 2. The forklift 1 can be used to dispose or retrieve the article stored within the tower 2. The detailed configuration and operation of the forklift can be readily referred to the above description.

Since the forklift 1 is incorporated with the static electricity eliminating device 23, accordingly, the static electricity accumulated in the warehouse system can be effectively eliminated, grounded and controlled.
