DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the transfer device of the present invention will be described below with reference to FIGS. 1 to 4.

In FIG. 1, an unmanned battery vehicle 1 runs along a trajectory preset by embedding guide wires in a floor F using electric power from a battery B held in a battery mounting section 2. As shown in FIG. 2, the battery mounting section 2 is formed by installing a plurality of rollers 4 between a pair of guide rails 3 extending parallel to the width direction of the vehicle, and the rollers 4'' are connected to a battery B. is placed. This battery B is held immovably by the hatch wrist collar 5, and after rotating this stopper 5 and retracting it from above the mounting part 2 as shown by the two-dot chain line (Fig. 1), it is moved to the side. By manually pulling the grasping tool 6, the battery B moves on the rollers 4. Note that a hook attendant hole 20a is formed between the front ends of both guide rails 3.

As shown in Fig. 2.3, a battery gear rear C is arranged adjacent to the battery mounting section 2 of the battery car 1, and a height difference between the battery gear rear C and the height difference between the battery gear rear C and the battery gear rear C is arranged so as to be rotatable at the end on the battery car 1 side. The arm-shaped mounting member 7 serving as an absorbing means is held in an upright retracted position by being held to the carrier C by a fastener 8. Similar to the mounting section 2 of the carrier C-carrier wheel 1, a transfer table 10 is formed by installing a plurality of rollers 9a at equal intervals in the length direction on a pair of guide rails 9 extending in parallel. , on both sides of which steps 11 are provided along the length. The transfer table 10 is provided with four bolt attachment parts (2 only two are shown) on its lower surface, and can be removed by adjusting the support bolts 13 screwed into the T&J parts 12. 10 heights are adjustable.

In particular, as shown in FIG. 2, a holding shaft 14 is hung on both guide rails 9 of the gear rear C at approximately the center in the longitudinal direction, and the holding shaft 14 is hung on both guide rails 9 of the gear rear C as shown in FIG. The rear ends of the pair of levers 15 extending forward are rotatably fitted onto the outside.

Note that a support piece 14a that projects diagonally downward is formed at the front end (right end) of both guide rails 9.

Furthermore, the mounting member 7 has a pair of parallel guide rails 16
A plurality of rollers 17 are hung at equal intervals in the length direction, and a mounting portion 18 is formed at the rear end of both guide rails 16 to project forward. In addition, handles 1 are provided at the front of the guide rails 16, respectively.
9 is attached, and a hook 20 formed by bending a metal plate into a hook shape is provided on the plate material stretched between the front ends of both guide rails 16.

In order to attach the mounting member 7 to both sides, a rotation shaft 21 is hooked and fixed between the parts 18, and the rotation shaft 21 is attached to the support piece 14a of the carrier C via the rotation shaft 21. The mounting member 7 rotates relative to the gear rear C each time it is attached at tJ.

One end of a pair of biasing bars 22 is fixed to this rotating shaft 2, and the other end of each biasing bar 22 is movable to the lever 5 on the carrier C side via a fitting piece 22a. It is fitted externally. One end of the lever 15 is supported by the rear end of the lever 15, and the pushing spring 23 wound around the lever 15 presses the biasing bar 22, so that when the mounting member 7 is in the mounting position in FIG. By applying a counterclockwise rotational force to the rotating shaft 21 via the biasing bar 22, the mounting member 7 is manually moved from the mounting position to the retracted position shown in FIG. It makes everything easier.

Note that the distances between the guide rails 3.9.16 of the battery vehicle 1 and the carrier C and the mounting member 7 are set equal, and the battery vehicle 1 and the carrier are connected via the mounting member A7 held at the mounting position. When these guide rails 3.9.16 are connected, a battery transfer path of a constant width is formed by these guide rails 3.9.16.

Then, when the battery car 1 and the carrier C are arranged on the same plane and the battery B is transferred, each roller 4
, 9a, and 17 are set to have the same height of the surfaces in contact with the battery B, so that the battery 13 can be smoothly moved within the transfer path.

In order to replace battery B due to exhaustion of battery B or the like, battery car 1 is stopped at a predetermined position near carrier C. Thereafter, the fastener 8 of the carrier C is removed, and the handle 19 of the mounting member 7 in the retracted position is pulled downward. Then, the push spring 2 applied to the rotating shaft 21 of the mounting member 7
3, the other end of the biasing bar 22 is moved to the lever 15.

In the above state, the stopper 5 of the battery car 1 is rotated to unlock the battery B, and then the gripper 6 of the battery B is pulled in the direction of the carrier C. Then, the battery B moves on the rollers 4 between the guide rails 3 of the mounting section 2 and reaches the top of the mounting member 7. If the gripper 6 of the battery B is still pulled, the battery B moves on the rollers 9a between the guide rails 9, moves on the rollers 17 between the guide rails 16 of the carrier C, and is then replaced with a new battery.

Thereafter, the replaced battery is moved in the opposite direction, placed on the mounting section 2 of the battery car 1, and then locked by the stopper 5.

During the transfer of the battery B described above, if the overall height of the battery car 1 is slightly different due to wear of the wheels of the battery car 1, unevenness of the road surface, etc., the rollers 4, 17 of the mounting section 2 of the Hara-Chiri car 1 and the carrier C may be slightly different. There is a difference in height between them. In this case, the mounting member 7 extending between the mounting portion 2 and the gear rear C is rotated up and down by an amount corresponding to the height difference, so that the height difference between the two and the gear rear C is absorbed, and the conventional This is a word in which the movement of battery B is obstructed by a step.
This embodiment can also be implemented in the following manner.

■Instead of unmanned battery vehicles, it can be applied to other industrial transportation vehicles such as battery-powered forklifts.

(2) The hook 20 and the hook hole 20a are omitted, and another locking mechanism is adopted.

(2) As a support mechanism for the carrier C, legs equipped with casters are used instead of the support bolts 13.
