Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to the structure of a battery cassette for storing batteries for driving a large number of unmanned carrier vehicles that self-propel within factories, work yards, etc.

BACKGROUND TECHNOLOGY The above-mentioned unmanned carriers are used in large numbers in factories, etc., and their operation is automated by computer control, and battery charging is also automated. In this case, battery charging depends on the operating condition of the transport vehicle,
In many cases, batteries are unloaded from transport vehicles and charged. Batteries for cycle service have a standard terminal voltage of 12V, and transport vehicles use battery cassettes containing multiple batteries connected in series. For maintenance such as charging, conventionally the cassettes are placed on free rollers installed inside the transport vehicle to facilitate loading and unloading.
In addition, cassette loading structures are used, such as one in which the electrical connection to the transport vehicle is made manually, or one in which the cassette is slid without using a free roller and electrical connection is made via a current collector. It was.

However, the former cassette loading structure is not fully automatic and is therefore unsuitable for unmanned operation of many transport vehicles, while the latter cassette loading structure has a current collector and a cassette positioning stopper located at the bottom of the cassette. However, there are disadvantages such as inconvenience in moving the cassette.

Problems to be Solved by the Invention The disadvantage of the conventional structure as described above is that the lower surface of the battery cassette is supported to move it in and out, so the present invention improves the movement structure of the battery cassette to eliminate the above disadvantages. The purpose of the present invention is to provide a battery cassette that is convenient for refilling electrolyte.

Measures to Solve the Problem This proposal fixes a cover to the top of a box that stores multiple batteries in a line in the direction of battery case arrangement, and At least six running rollers that run on ceiling rails provided on the unmanned carrier are provided on both sides of the cover, and guide rollers that contact the vertical sides of the ceiling rails are provided on both the front and rear sides of the cover, and the front and rear ends of the cover The above object has been achieved by a structure in which a stopper and a conductor connected to the terminal of the battery and in contact with the external current collector are provided at different lateral positions on the upper surface.

Function Cycle service batteries usually have multiple battery cases in one case depending on the battery voltage.
The batteries are arranged in a row and terminals are provided at both ends, and if a plurality of batteries are stored in a row in the battery cassette in the alignment direction, all the battery cases are arranged in a row and automatic water refilling is performed. Conveniently, the battery cassette is elongated in the alignment direction. Therefore, when moving a cassette between parts of a transport vehicle or charging equipment for battery replacement or charging, at least six running rollers stabilize the transfer of the cassette at the ceiling rail joint, allowing it to move forward and backward. The left and right guide rollers function to smooth the transfer. Then, when the cassette is inserted into a predetermined position in a transport vehicle or charging equipment, the conducting current automatically contacts a current collector provided in the transport vehicle or charging equipment, and charging and discharging is performed.

Embodiment In FIGS. 1 to 3, a battery cassette 1 has a frame-shaped cover 3 made of angle material fixed to the top of a rectangular bottomed box 2, and 12V cycle service batteries 4, 4 are installed inside. are stored so that each battery case is arranged in a row. cover 3
A shaft support block 5 is fixed symmetrically to the longitudinal center and the front and rear upper surfaces of the roller, respectively, and a running roller 7 is pivotally supported to the support block 5 via a spacer 6 so as to be opposite to each other on the left and right.

Arms 9 projecting forward and backward of the cover 3 are bolted to pillars 8 fixed to the four corners of the upper surface of the cover 3, and a guide roller 10 is pivotally supported at the top of the tip of the arm 9.

Ceiling rail 11 installed on transport vehicles, charging equipment, etc.
The rail part is formed by integrally forming a top part 12 to be fixed to a rail support, a side part 13 with both sides of the top part 12 bent at right angles, and a rail part 14 with a lower part of the side part folded back horizontally. A running roller 7 runs on the cassette 14, and a guide roller 10 comes into contact with the outer surface of the side part 13 to guide and run the cassette 1 without moving it from side to side. Particularly at the joint portion of the ceiling rail 11, the side surface portion 13 is curved slightly outward in order to facilitate the transfer of the guide roller 10.

A pair of ear plates 15 fixed to the front and rear surfaces of the cover 3
and the ear plates 16 protruding from the front and rear sides of the box 2 so as to be in contact with the ear plates 16, and the bolts 17 are passed through the cover 3.
is fixed to the case 2, and the hook of a transfer device or the like is engaged with the bolt 17 to move the cassette 1 back and forth.

A stopper 18 is installed at the center of the top of both front and rear ends of the cover 3.
A locking device (not shown) provided inside the transport vehicle or in a charging facility or the like is engaged with the stopper 18 to position and lock the cassette 1 in a predetermined position.

A pair of conductors 19 are attached to one end of the cover 3 via an insulator. As shown in detail in Figure 4,
The conductor 19 consists of a pair of metal plates elongated in the longitudinal direction fixed on the cover 3 via insulators 20, 21, etc. with bolts 22, the front and rear of which are inclined downward, and the connection provided at the rear. It is electrically connected to a terminal of the battery 4 by a screw 23.

In the interior of a transport vehicle, charging equipment, etc., the bases 25 of a pair of leaf springs 24 are bolted to the lower side of the upper surface 12 of a ceiling rail through an insulator, and the tips of the leaf springs 24 are attached to the upper surface 12. The fork 26 made of insulator is inserted into the gap to restrict vertical movement, and the current collector 29 is bolted to the intermediate portion of the leaf spring 24 via insulators 27 and 28. The collector 29 is pressed into contact with the flat part 30 of the conductor 19 by the elasticity of the leaf spring 24 to supply power from the battery 4 to equipment in the transport vehicle, or to supply charging power from the charging equipment to the battery 4.

The feeder 19 loads the cassette 1 in the direction of the arrow,
Alternatively, since the battery 4 is brought into contact with and separated from the current collector 19 by being pulled out in the opposite direction, no human effort is required to electrically connect the battery 4 when replacing or charging the battery.

Effects of the invention The present invention is as described above, and since the battery cassette is equipped with a predetermined number of running rollers and guide rollers on the upper part and is guided and moved on the ceiling rail, it can be smoothly moved in and out of the transport vehicle or charging equipment, and can be operated unattended. It is convenient, and because the stopper and power supply are located above the cassette and close to the ceiling rail, it is possible to accurately position the cassette in a transport vehicle or in a charging facility, and it does not interfere with the movement of the cassette. In addition, all the battery containers in the cassette are aligned in the direction of movement of the cassette, so when performing automatic water replenishment, water can be refilled sequentially from the battery container at one end to the container at the other end. This has the effect that it can be easily configured.
