Abstract

PROBLEM TO BE SOLVED: To provide an order picker capable of running also in the direction of a running drive device by assuring a visual field from a driver. SOLUTION: A load handling device 22 for lifting a work stand 13 and a control device 23 for controlling the running steering of a vehicle 11 are installed on a rear plate frame 15 at the rear of a mast 12 concentratedly around the upper part of he running drive device 19 so as not to be positioned above batteries 20 on both right and left sides. The load handling device 22, control device 23, running drive device 19, and right and left side batteries 20 are covered by a cover formed along the overall contour line of these devices. Even when a driver runs the vehicle in the opposite direction of a fork 14, i.e., in the direction of the running drive device 19, the visual field of the driver can be sufficiently assured for easier running.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an order picker provided with a worktable which can be raised and lowered.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view of a conventional order picker disclosed in JP-A-8-231199. A workbench 2 supported by a pair of masts 1 so as to be able to move up and down is provided at the front part of the order picker, and a fork 3 for cargo handling work is fixed to the front part of the workbench 2.
Behind the mast 1, a functional product chamber 4 having a substantially T-shape when viewed from the front is provided. A traveling drive device 7 including a drive motor 5 and drive wheels 6 and the like is housed in the lower half of the functional room 4, and although not shown,
A cargo handling device for raising and lowering the workbench and a control device for controlling traveling are housed in the upper half of the functional room 4. A pair of batteries 8 are housed in a concave space defined by the lower left and right outer portions of the functional product chamber 4.

[0003]

However, as shown in FIG. 5, since the upper half portion of the functional chamber 4 has a predetermined height and extends to the upper portions of the batteries 8 on both left and right sides, The direction opposite to the fork 3, that is, the traveling drive device 7
If you try to drive the vehicle in the direction of
The upper half part of the vehicle obstructs the visual field of the driver on the workbench 2. Therefore, there is a problem that traveling in the direction of the traveling drive device 7 becomes difficult.

The present invention has been made in order to solve such a problem, and provides an order picker which secures a visual field from a driver and enables traveling in the direction of a traveling drive device. With the goal.

[0005]

SUMMARY OF THE INVENTION An order picker according to the present invention is provided with a workbench supported by a pair of masts so as to be able to move up and down on one side of a mast and a pair of traveling drive devices arranged on the other side of the mast. In the order picker provided with divided batteries, the cargo handling device for raising and lowering the workbench and the control device for controlling traveling are concentrated around the upper portion of the traveling drive device with a space above the battery. It has been arranged. Further, a pair of batteries may be installed on both left and right sides of the mast.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partial perspective view of the order picker according to the embodiment of the present invention with a part thereof omitted. A pair of masts 12 are arranged upright in the center of the vehicle 11, and a work table 13 provided in front of the mast 12 is supported so as to be able to move up and down. A fork 14 for cargo handling work is fixed to the front part of the work table 13, and the work table 13 and the fork 14 move up and down as a unit. In the present embodiment, the fork side is the front of the vehicle for convenience.

On the other hand, a back plate frame 15 is provided on an upper portion of a frame that is upright in the center of the vehicle 11 among frames that form the framework of the whole vehicle 11, and the left and right sides of the mast 12 are provided from both side edges of the back plate frame 15. The mast 12 is supported by the arm frames 16 extending to both sides. A travel drive device 19 including a drive motor 17 and drive wheels 18 is provided behind the mast 12.
A pair of batteries 20 serving as a drive source of the vehicle 11 are arranged on both left and right sides of the mast 12 and the traveling drive device 19.
That is, the front portions of the pair of batteries 20 are located below the arm frames 16 attached to the left and right sides of the mast 12, respectively, and are arranged adjacent to the rear portion of the work table 13. Therefore, compared to the case where the mast and the battery are aligned in the front-rear direction of the vehicle as in the conventional order picker shown in FIG. 5, the total length of the vehicle becomes shorter, which improves the turnability of the order picker. I was able to.

A rear plate frame 1 at the rear of the mast 12
5. A hydraulic oil tank 2 for storing hydraulic oil used in a cargo handling device described later in a space formed by the drive motor 17 of the traveling drive device 19 and the pair of batteries 20.
1 is arranged. The pair of batteries 20 are arranged at the lowest possible position in the vehicle 11, and as a result, a sufficient space is formed above the battery 20.

Next, as shown in FIG.
The cargo handling device 22 for raising and lowering the vehicle and the control device 23 for controlling the traveling steering and the like of the vehicle 11 are concentrated around the upper portion of the traveling drive device 19 so as not to be located above the batteries 20 on the left and right sides, 12 Rear plate frame 1
5 is attached. In this way, by disposing the cargo handling device 22 and the control device 23 in a concentrated manner on the back plate frame 15, the spaces formed above the batteries 20 on the left and right sides are occupied by the cargo handling device 22 and the control device 23. It will be in the open state without being.

Further, as shown in FIG. 3, the mast 1
From the left and right sides of 2 to the rear, openable cover 2 on the top
A cover 24 composed of 4a and a lower fixed cover 24b is attached. As described above, the cargo handling device 22 and the control device 23 are concentrated on the upper part of the traveling drive device 19 in the center in the width direction of the vehicle 11, and are arranged near the mast 12 in front of the traveling drive device 19 in the front-rear direction of the vehicle 11. By removing the cover 24, the left and right batteries 20 are removed.
Of the vehicle 11 and the rear side of the vehicle 11 above the traveling drive device 19 are open without any member. Cover 24
Is the upper part of the left and right batteries 20 opened in this way,
And the upper part of the traveling drive device 19 along the rear side of the vehicle 11, that is, along the overall outer shell shape of the cargo handling device 22, the control device 23, the traveling drive device 19 and the left and right batteries 20. It has such a shape that the upper corner portion of the box body is removed by a large inclination without wastefully forming an internal space therebetween. Therefore, even when the driver drives the vehicle in the direction opposite to the fork 14, that is, in the direction of the traveling drive device 19, the driver's visual field is sufficiently secured, and not only the direction of the fork 14 but also the traveling drive device 19 is driven.
You can now easily drive in the direction of.

Further, as shown in FIG. 4, when the openable cover 24a on the upper side is opened, the upper portion of the battery 20 is opened, so that the battery 20 can be moved to the battery 20 for maintenance without moving. It has become possible to easily replenish the water.

[0012]

As described above, according to the order picker of the present invention, the cargo handling device for raising and lowering the workbench and the control device for controlling the traveling are driven and driven in a space above the battery. Since the device is concentrated around the upper part of the device, the driver's view can be secured and traveling in the direction of the traveling drive device is possible.
