  The process of mounting the battery 2 on the vehicle 1 by the above-described battery mounting device 3 includes a preparation process in the standby zone 90, a charging process from the standby zone 90 to the transport line 100, and a positioning by coupling to the vehicle 1 on the transport line 100. This is roughly divided into a setting step for mounting the battery 2, a mounting step for mounting the battery 2 at a specified position on the vehicle 1, and a returning step from the transport line 100 to the standby zone 90. Next, the operation of each part of the battery mounting device 3 in each step will be described.

(Preparation process)
The preparation step is a pre-processing step of loading the battery 2 into the battery mounting device 3 set at the initial position of the standby zone 90. The battery 2 transported by the battery transport line 91 is transferred to the battery holding unit 52 of the battery mounting device 3. Specifically, as shown in FIG. 5, the battery 2 is positioned by fitting the guide pin 92 and the tip of the guide rail 53 of the battery mounting device 3 through the bracket 2a of the battery 2 on the battery transfer line 91. Then, the battery 2 is delivered from the battery transfer line 91 to the battery mounting device 3.

(Input process)
When the target vehicle 1 is transported to the transport line 100, it is confirmed that the vehicle 1 has reached the reference position, and the prepared battery mounting device 3 is moved from the line-side standby zone 90 to the rear of the vehicle 1. Then, it is put into the transport line 100.

(Setting process)
As shown in FIG. 6, the stopper 23 is moved to the rear of the vehicle 1 until the stopper 23 comes into contact with the battery mounted device 3, and the battery mounted device 3 is connected to the vehicle 1 via the connecting arm 21 and connected thereto. When the connecting arm 21 is connected to the vehicle 1, the position of the battery mounting device 3 in the lateral direction (vehicle width direction) of the vehicle 1 is determined by the fixed guide beam 12 and the guide beam 13 as shown in FIG. 7. .

  That is, the position of the battery mounting device 3 in the front-rear direction is determined by bringing the stopper 23 of the battery mounting device 3 into contact with the rear skirt 1a at the rear of the vehicle 1, and further, as shown in FIG. The fixed guide beam 12 is moved to contact the inner wall on one side in the lateral direction of the opening 1b at the rear of the vehicle 1. In this state, as shown in FIG. 7B, the movable bed 11 is moved in the opposite direction, and when the movable guide beam 13 contacts the inner wall on the other side of the opening 1b, the movable bed 11 is stopped. Thereby, the positioning in the lateral direction is performed (the lateral movement amount A of the movable bed 11).

  After the positions of the battery mounting device 3 in the front-rear direction and the lateral direction with respect to the vehicle 1 are determined, the connecting arm 21 is raised, and as shown in FIG. The engaging member 22 at the tip of the connecting arm 21 is fitted into the reference hole h1. Thereby, the vehicle 1 and the battery mounting device 3 are connected and integrally connected. The distance from the stopper 23 to the engaging member 22 at the end of the connecting arm 21 is set to be equal to the distance B from the rear skirt 1a of the vehicle 1 to the first reference hole h1.

  Note that the connection between the vehicle 1 and the battery mounting device 3 is not limited to the fitting with the first reference hole h1 of the skeletal member 1c at the lower part of the vehicle 1, but may be a structure arranged on the left and right with respect to the center of the vehicle body. A fixing hole in the body may be used. For example, as shown in FIG. 9, the distal ends of the connecting arms 21 ′ are inserted into the opening ends of the left and right frames F to which the bumper beams are mounted at the rear of the vehicle, and the bumper beam mounting holes are orthogonal to the axial direction of the frame F. Alternatively, the pins 22 'may be joined by projecting the pins 22' from the tips of the connecting arms 21 '.

  Further, in a state where the vehicle 1 and the battery mounting device 3 are positioned and connected, the upper beam 41 of the pier 40 is moved forward. Then, as shown in FIGS. 10 and 11, the upper beam 41 is lowered at a position (distance C from the stopper 23) corresponding to the second reference hole h2 opened in the cabin of the vehicle 1, and the indoor guide legs 43 Is fitted into the second reference hole h2 for positioning, and the distal end of the support leg 42 is seated in the vehicle. Thereby, the load when the battery 2 is transported to the mounting position via the transport rail 51 can be supported.

(Mounting process)
As shown in FIG. 12, the battery holding unit 52 holding the battery 2 is moved forward via the transfer rail 51, and the guide rail 53 attached to the rear of the battery holding unit 52 and the battery provided on the vehicle 1 side The battery holding unit 52 is stopped at a position corresponding to the reference pin P1 serving as a reference for the mounting position. Then, the transport rail 51 is lowered, and as shown in FIG. 13, the battery mounting position is determined by fitting the guide rail 53 and the reference pin P1, and the transport rail 51 is lowered again, as shown in FIG. 2 is seated on the vehicle body.

  After the battery 2 is seated on the vehicle body, the bracket 2a of the battery 2 is bolted to the vehicle body using a fastening tool mounted on the battery mounting device 3 and fixed to the vehicle 1.

(Return process)
After the battery 2 is mounted on the vehicle 1, the clamp claws 52 a of the battery holder 52 are released, the transport rail 51 is raised, and the upper beam 41 is raised. Further, the movable bed 11 is moved to remove the movable guide beam 13 from the vehicle body, and the connecting arm 21 at the lower part of the vehicle body is lowered to detach the battery mounting device 3 from the vehicle 1. Then, the battery mounting device 3 is moved from the transport line 100 of the vehicle 1 to the standby zone 90, and returned to the initial position on the line side of the battery transport line 91.

  The processing flow of each of the above steps is shown in the flowcharts of FIGS. Hereinafter, the flow of the processing of each step will be described. Although detailed description is omitted, in each process, it is appropriately checked whether the battery 2 is properly loaded in the battery mounting device 3 and whether an abnormality has occurred during the operation of each unit. If an abnormality is detected, an alarm is issued and the apparatus is stopped.

When the feed amount has reached the specified amount, the forward movement of the upper beam 41 is stopped in step S17, the upper beam 41 is lowered in step S18, and the descending feed amount of the upper beam 41 is set in step S19. It is confirmed whether or not the seating of the distal end portion 42 and the specified amount that can be fitted into the second reference hole h2 at the distal end portion of the indoor guide leg 43 have been reached (see FIGS. 10 and 11). Then, when the downward feed amount reaches the specified amount, the lowering of the upper beam 41 is stopped in step S20, and the process proceeds to the mounting process shown in FIG.

  In the mounting process of FIG. 17, the battery holding unit 52 of the transport rail 51 is moved forward in step S21, and it is checked in step S22 whether the feed amount has reached a specified amount. When the feed amount of the battery holder 52 reaches the specified amount, the movement of the battery holder 52 is stopped in step S23, and the transport rail 51 is lowered in step S24. Due to the lowering of the transport rail 51, the battery holder 52 is lowered.

  After the battery holding unit 52 is lowered, it is checked in step S25 whether the descending feed amount of the transport rail 51 has reached a specified amount, and when the feed amount has reached the specified amount, the transport rail 51 is temporarily stopped in step S26. Let it. Next, the process proceeds to step S27, in which the transport rail 51 is lowered again to lower the guide rail 53 of the battery holding unit 52. In step S28, the downward feed amount of the transport rail 51 is changed to the reference pin P1 of the vehicle body. Check whether the specified amount to fit has been reached.

  When the descending feed amount of the transport rail 51 reaches the specified amount at which the guide rail 53 is fitted to the reference pin P1 in step S28, the process proceeds to step S29, and the descending of the guide rail 53 due to the descending of the transport rail 51 is stopped. Then, in step S30, the transport rail is further lowered to seat the battery 2 held by the battery holding unit 52 at the mounting position of the vehicle body, and after confirming the seating, the process proceeds to the return process shown in FIGS. .

  In the return process shown in FIGS. 18 and 19, the clamp claws 52a of the battery holder 52 are released in step S31, and the transport rail 51 is raised in step S32. Then, in step S33, it is confirmed whether or not the transport rail 51 has returned to the original position before descending.

  Further, the upper beam 41 is raised in step S35, and it is confirmed in step S36 whether the upper beam 41 has returned to the original position before the lowering. Then, when the upper beam 41 returns to the original position, the ascent of the upper beam 41 is stopped in step S37.

  Next, the process proceeds to step S38, in which the battery holding unit 52 is moved backward on the transport rail 51 in a direction away from the vehicle body. Then, in step S39, it is confirmed whether or not the battery holding unit 52 has returned to the original position before the forward movement. When the battery holding unit 52 has returned to the original position, the process proceeds to step S40, and the movement of the battery holding unit 52 is stopped.

  Further, in step S41, the upper beam 41 is moved backward in a direction away from the vehicle body, and in step S42, it is confirmed whether or not the upper beam 41 has returned to the original position before the forward movement. When the upper beam 41 returns to the original position, the movement of the upper beam 41 is stopped in step S43, and the process proceeds to step S44.

  In step S44, the movable bed 11 is moved to separate the movable guide beam 13 from the side wall of the vehicle body opening, and in step S45, it is confirmed whether the movable bed 11 has returned to the original position before the lateral movement. . Then, when the movable bed 11 returns to the original position, the movement of the movable bed 11 is stopped in step S46.

  Next, the process proceeds to step S47, in which the connecting arm 21 is lowered to release the connection between the vehicle 1 and the battery mounting device 3, and it is confirmed in step S48 whether the connecting arm 21 has returned to the original position before the ascending. . When the connecting arm 21 returns to the original position, the lowering of the connecting arm 21 is stopped in step S49.
