In use, the pressure restraining means 86 rotates the base of the male screw portion 90 (the portion protruding outward of the container 88) to move the restraining jig 89 horizontally in the container 88, for example, transporting. By bringing the restraining jig 89 into contact with the side surface of the secondary battery through the opening formed in the side portion of the tray 11, a plurality of secondary batteries can be pressurized and restrained along the arrangement direction.

The charge / discharge inspection equipment 91 shown in FIG. 14 includes an arm device 17d and a charge / discharge inspection shelf 92 provided with two accommodating portions 15 for accommodating the transport tray 11 in the height direction and the width direction, respectively. (See FIG. 9). In this arm device 17d, a fire extinguishing nozzle (an example of fire extinguishing means) 93 for injecting a fire extinguishing agent is attached instead of the operating means 18 which is attached and detachable to the front side of the arm main body 18a. The fire extinguishing nozzle 93 can be replaced with the above-mentioned operating means 18 or the like by using, for example, an automatic tool changing device or the like.
The tip side of the fire extinguishing nozzle 93 can be inserted and removed from the insertion hole 94 formed in the charge / discharge inspection shelf 92. For example, when a fire breaks out in the accommodating portion 15, the fire extinguishing nozzle 93 is accommodated through the insertion hole 94. The digestive agent can be sprayed into the portion 15. As the fire extinguishing agent, for example, an inert gas such as water (fire extinguishing water), carbon dioxide (CO ₂ ), and nitrogen gas (N ₂ ) can be used.

In use, when a fire breaks out in the accommodating portion 15, the arm device 17d is operated, the tip side of the fire extinguishing nozzle 93 is inserted into the insertion hole 94, and the digestive agent is sprayed into the accommodating portion 15. By providing the fire extinguishing nozzle 93 with a detection sensor that detects either one or both of the flame and smoke, it is possible to intensively inject the digestive agent toward the ignition unit (ignition source). At this time, by keeping the drawer portion 82 in the closed state, it is possible to prevent the flame and smoke at the time of ignition and the fire extinguishing agent from flowing out from the accommodating portion.
Normally, it was necessary to provide the charge / discharge inspection shelf with a pipe for supplying the fire extinguishing agent to the charge / discharge inspection shelf and a nozzle provided in this pipe for injecting the digestive agent into each accommodating portion or the like. .. However, by providing the fire extinguishing nozzle in the arm device, the above-mentioned piping and the like become unnecessary, and the digestive agent can be more accurately sprayed to the ignition portion.

The measuring probe pin 97 connects a secondary battery to a measuring instrument (not shown), whereby an electrical measurement (for example, voltage measurement and / or resistance (DC resistance) of the secondary battery is performed. And AC resistance) measurement) can be performed (has a measurement function). Since the time required for this electrical measurement is shorter than the time required for the charge / discharge test, it is possible to perform electrical measurement while transferring the transport tray to the charge / discharge inspection shelf.

By incorporating a weight measuring means (for example, a load sensor) capable of measuring the weight of the secondary battery and / or the transport tray 11 in the arm device 17e, the transport tray 11 is held by the operating means 96. , Weight can also be measured.
Normally, the above-mentioned various measurements are performed on the conveyor, but in this case, it is necessary to temporarily stop the conveyor each time the measurement is performed, and in order to perform the measurement reliably, the conveyor is equipped with a position member or stopper for the transport tray. Etc. had to be provided. However, according to the configurations shown in FIGS. 15A and 15B, the measurement can be performed while continuously transporting the transport tray 11 without stopping the first conveyor 61, so that the working time can be shortened and the work time can be shortened. The positioning member, stopper, and the like of the conveyor tray 11 are not required, and the device configuration can be simplified.

In the modification shown above, the arm device has the functions conventionally provided in the charge / discharge inspection shelf (shutter opening / closing function, drawer opening / closing function, charge / discharge probe pin elevating function, fire extinguishing water injection function). Therefore, the configuration of the charge / discharge inspection shelf can be simplified, and for example, the charge / discharge inspection shelf can be made compact and the cost of the charge / discharge inspection facility can be reduced.
