Linear bushings 124 and 124 with flanges are attached to the other piece of the slide bracket 122 side by side in the same vertical plane (left and right direction in FIG. 8) by fastening parts such as bolts (not shown).

  The shafts 126 and 126 have a contact portion 128 coupled to one end by a fastening part such as a bolt (not shown), and end plates 138 and 138 are attached to the other end by a fastening part such as a bolt (not shown). The end plates 138 and 138 prevent the shafts 126 and 126 from coming off.

The contact portion 128 includes insulating blocks 132a and 132b, and contact rollers 134 and 134 as power transmission terminals that are rotatably sandwiched between the insulating blocks 132a and 132b by holding plates 136 and 136. The insulating blocks 132a and 132b are made of a non-conductive material such as a resin, and are allowed to move relative to each other only in the axial direction of the shafts 126 and 126 and are combined with each other.
That is, the surface of the insulating block 132a facing the insulating block 132b (the right side in FIG. 8) is formed with a concave groove along the axial direction of the shaft 126, 126, and the surface of the insulating block 132b facing the insulating block 132a. Convex portions along the axial direction of the shafts 126 and 126 are formed on the left side in FIG. 8, and the convex portions are fitted into the concave grooves so that the axes of the shafts 126 and 126 of the insulating block 132a and the insulating block 132b are formed. Relative movement with respect to the direction is possible.

  The presser plates 136 and 136 and the contact rollers 134 and 134 are made of a conductive material such as copper. The contact rollers 134 and 134 are respectively connected to the positive terminal and the negative terminal of the charger 50 through the presser plates 136 and 136. They are connected by a power line L. Accordingly, one of the contact rollers 134 and 134 serves as an anode power transmission terminal, and the other serves as a cathode power transmission terminal.

As shown in FIG. 8, the action lever 32 is configured as a substantially L-shaped lever member having a short side portion 32a and a long side portion 32b, and is fixed to the base 22 by a stripper bolt SB. The bracket 25 is rotatably attached.

  As shown in FIG. 8, an elliptical hole 33b is formed at the distal end of the long side portion 32b of the action lever 32, and the slide bracket 122 and the slider main body 120b are formed by bolts B as shown in FIG. The attached miniature bearing 150 is inserted into the elliptical hole 33b, and the action lever 32 and the slide bracket 122 are connected. That is, the slide plate 104 and the slide bracket 122 are connected by the action lever 32.

  In this way, the short side portion 32a is connected to the slide plate 104 and the long side portion 32b is connected to the slide bracket 122, so that the movement of the slide plate 104 to the rear frame 26 side is reduced from the stripper bolt SB to the miniature bearing 112b.

The micro switch 36 is configured as a limit switch that is turned on by depressing the lever. When the micro switch 36 is turned on, the electric power from the charger 50 is supplied via the power line L to the contactor 20 (in detail). Is supplied to contact rollers 134 and 134) as power transmission terminals. The microswitch 36 is attached to the switch bracket 34 so that the microswitch 36 is turned on when the slide plate 104 has moved a predetermined distance toward the rear frame 26 side.
Here, in the embodiment, the predetermined distance is set to a relatively short distance from when the slide plate 104 starts to move to the rear frame 26 until it completely moves, and the slide plate 104 moves to the rear frame 26 side. It turns on at a relatively early stage.

  As shown in FIG. 1, the automatic guided vehicle 80 drives a drive unit (not shown) attached to the lower surface of the vehicle body 82 using electric power from a lithium ion battery LB mounted on the upper portion of the vehicle body 82, and is provided in the drive unit. It is configured to travel along the induction band 2 while detecting the induction band 2 by a magnetic sensor (not shown). An arm 84 and a power receiving terminal board 86 are provided on the side surface of the vehicle body 82.

Both ends of the arm 84 are fixed to the side surface of the vehicle body 82 with bolts B, and inclined portions 84a and 84a formed so as to gradually move away from the side surface of the vehicle body 82 from both ends to the inside. It is comprised from the parallel part 84b formed in parallel with the side surface of the vehicle body 82, connecting the part 84a and 84a. That is, the arm 84 is formed as a trapezoidal frame member having the parallel portion 84b as the upper bottom and the side surface side of the vehicle body 82 as the lower bottom.
The arm 84 is attached to the side surface of the vehicle body 82 so that the height of the arm 84 attached from the floor surface is the same as the height position of the miniature bearing 110b in the dog follower 110 of the contactor 20 from the floor surface.

FIG. 10 is an enlarged view showing a part of the side surface of the vehicle body 82 of the automatic guided vehicle 80 in an enlarged manner.
As shown in FIG. 10, the power receiving terminal board 86 includes a pair of power receiving terminals 86 a and 86 a arranged in the vertical direction, and is arranged below the arm 84. The power receiving terminals 86a and 86a are made of a conductive material such as copper, for example, and are connected to the positive terminal and the negative terminal of the lithium ion battery LB through the power line L as shown in FIG. Therefore, one of the power receiving terminals 86a and 86a is an anode power receiving terminal and the other is a cathode power receiving terminal.
The arrangement of the power receiving terminals 86 a and 86 a in the traveling direction of the automatic guided vehicle 80 corresponds to the parallel portion 84 b of the arm 84.

Next, the operation of the charging apparatus 10 of the embodiment configured as described above, particularly the operation when charging the lithium ion battery LB of the automatic guided vehicle 80 will be described.
FIG. 11 is a state diagram showing a state in which the arm 84 contacts the miniature bearing 110b of the dog follower 110 and the slide plate 104 starts to move toward the rear frame 26. FIG. 12 shows a state in which the micro switch 36 is turned on. FIG. 13 is a state diagram showing a state in which the contact rollers 134 and 134 and the power receiving terminals 86a and 86a of the automatic guided vehicle 80 are in contact with each other as the slide bracket 122 moves to the front frame 24 side. FIG. 14 is an explanatory view showing a state when the action lever 32 rotates.

When the automated guided vehicle 80 travels along the induction band 2 to, for example, the work station where the contactor 20 of the charging device 10 is installed in order to charge the lithium ion battery LB, it is fixed to the side surface of the vehicle body 82. The inclined portion 84 a in the arm 84 and the miniature bearing 110 b of the dog follower 110 in the moving portion 28 of the contactor 20 abut.
As the automatic guided vehicle 80 further advances, the slide plate 104 is resisted against the spring force of the compression springs 108 and 108 via the miniature bearing 110b by the cam action of the inclined portion 84b of the arm 84 as shown in FIG. Move to the rear frame 26 side.
At this time, as shown in FIG. 12, the switch dog 114 attached to the side surface of the leg 104b of the slide plate 104 is in a state where the lever of the micro switch 36 is completely pushed down, and the power from the charger 50 passes through the power line L. To the controllers 134 and 134.

As the slide plate 104 moves toward the rear frame 26, the miniature bearing 112b of the roller member 112 moves while pushing the inner wall of the long hole 33a of the short side portion 32a of the action lever 32, as shown in FIG. Thereby, the action lever 32 rotates with the stripper bolt SB as a fulcrum.
This rotation is in the counterclockwise direction, that is, the direction in which the long side portion 32a faces the front frame 24 (right side direction in FIG. 14). Accordingly, the slide bracket 122 connected to the long side portion 32b via the miniature bearing 150 moves to the front frame 24 side.
Here, in the embodiment, the contact portion between the contactor 20 and the inclined portion 84a of the arm 84 and the connecting portion between the slide plate 104 and the slide bracket 122 and the action lever 32 all use the miniature bearings 110b, 112b, and 150. Therefore, relative sliding can be made smooth.

As the slide bracket 122 moves to the front frame 24 side, the contact portion 128 coupled to the tips of the shafts 126 and 126 also moves to the front frame 24 side. As shown in FIG. 13, when the miniature bearing 110b reaches the parallel portion 84b of the arm 84, the movement of the slide plate 104 to the rear frame 26 side is maximized, and the slide bracket 122 moves to the front frame 24 side. Therefore, the contact portion 128 protrudes further to the front side (right side in FIG. 13) than the front frame 24.
Thus, the contact rollers 134 and 134 of the contact portion 128 come into contact with the power receiving terminals 86 a and 86 a of the automatic guided vehicle 80. At this time, since the power from the charger 50 is supplied to the contact rollers 134 and 134 via the power line L, the power is also supplied to the power receiving terminals 86a and 86a via the contact rollers 134 and 134. Then, charging of the lithium ion battery LB is started.

  Note that when the contact rollers 134 and 134 are in contact with the power receiving terminals 86a and 86a, the contact portion 128 is pushed back in a direction in which the protruding amount decreases. That is, since the compression springs 130 and 130 are compressed between the flanged linear bushings 124 and 124 and the contact portion 128, the contact rollers 134 and 134 are energized by the springs 130 and 130. In contact with the power receiving terminals 86a and 86a. Thereby, the contact between the contact rollers 134 and 134 and the power receiving terminals 86a and 86a is ensured.

  The amount of protrusion of the contact portion 128 takes into account various variations (such as the size variation of each part of the contactor 20 and the size of the arm 84, the mounting error of the contactor 20, the travel position of the automatic guided vehicle 80 on the guide band 2). However, the amount is set such that it can contact the power receiving terminals 86a and 86a in a state where the spring force is applied.

  The contact rollers 134 and 134 can be moved relative to each other in the axial direction of the shafts 126 and 126 via the insulating blocks 132a and 132b. For example, the automatic guided vehicle 80 is tilted due to unevenness of the floor surface. This charging can be sufficiently absorbed even when the battery is charged with the power, and the contact rollers 134 and 134 can be reliably brought into contact with the power receiving terminals 86a and 86a.

FIG. 15 is a state diagram illustrating a state of the protruding moving unit 30 in the contactor 20 when the automatic guided vehicle 80 is charged in a tilted state.
As shown in FIG. 15, when the automatic guided vehicle 80 is inclined upward in a direction away from the contactor 20, the lower contact roller 134 is pushed into the rear frame 26 side more than the upper contact roller 134. By absorbing the inclination of the automatic guided vehicle 80, the contact rollers 134 and 134 are reliably in contact with the power receiving terminals 86a and 86a.

According to the charging device 10 of the embodiment described above, when the arm 84 of the automatic guided vehicle 80 contacts the miniature bearing 110b of the dog follower 110, the slide plate 104 in the moving unit 28 moves to the opposite side to the automatic guided vehicle 80. Then, the movement of the slide plate 104 to the side opposite to the automatic guided vehicle 80 is reversed by the action lever 32 to the protruding movement of the contact rollers 134 and 134 as power transmission terminals in the protruding portion 30 to the automatic guided vehicle 80 side. The contact rollers 134 and 134 are brought into contact with the power receiving terminals 86a and 86a. That is, the controllers 134 and 134 as power transmission terminals are protruded toward the automatic guided vehicle 80 only when charging. Therefore, the danger is low as compared with the case where the power transmission terminal is always protruded toward the automatic guided vehicle 80 side.
Further, the movement of the slide plate 104 on the side opposite to the automatic guided vehicle 80 is mechanically reversed by using the action lever 32 to the protruding movement of the contact rollers 134 and 134 as power transmission terminals to the automatic guided vehicle 80 side. Because of the structure, there is no need to provide a separate drive mechanism such as an electric motor or cylinder. As a result, charging can be performed with a safe and simple configuration.

Further, according to the charging device 10 of the embodiment, when the inclined portion 84a of the arm 84 of the automatic guided vehicle 80 comes into contact with the miniature bearing 110b in the dog follower 110, and the slide plate 104 starts to move to the rear frame 26 side, the micro switch Since the switch dog 114 and the micro switch 36 are installed so that the switch 36 is turned on, it is not necessary to detect with a sensor or the like whether or not the contact rollers 134 and 134 as power transmission terminals have contacted the power reception terminals 86a and 86a.
In addition, since the micro switch 36 is turned on at a relatively fast stage after the slide plate 104 starts to move toward the rear frame 26, that is, before the contact rollers 134 and 134 contact the power receiving terminals 86 a and 86 a, the contact roller 134. , 134 starts charging immediately after contacting the power receiving terminals 86a, 86a.

  Furthermore, according to the charging device 10 of the embodiment, the short side portion 32a of the action lever 32 is connected to the slide plate 104, and the long side portion 32b of the action lever 32 is connected to the slide bracket 122. For the movement toward the frame 26 side, the slide bracket 122 protrudes toward the front frame 24 according to the lever ratio which is the ratio of the distance from the stripper bolt SB to the miniature bearing 112b and the distance from the stripper bolt SB to the miniature bearing 150. Can be reversed to move. That is, by moving the small slide plate 104 toward the rear frame 26, the slide bracket 122 can be largely moved to project toward the front frame 24.

Further, according to the charging device 10 of the embodiment, the contact rollers 134 and 134 are in contact with the power receiving terminals 86a and 86a in a state where the spring force is urged by the compression springs 130 and 130, respectively. Moreover, the protrusion amount of the contact portion 128 takes into consideration various variations such as the dimensional variation of each part of the contactor 20, the dimensional variation of the arm 84, the attachment error of the contactor 20, and the travel position of the automatic guided vehicle 80 on the guide band 2. However, it is set to an amount that can contact the power receiving terminals 86a and 86a in a state where the spring force is applied. As a result, contact between the contact rollers 134 and 134 as power transmission terminals and the power receiving terminals 86a and 86a can be ensured.
Further, since the contact rollers 134 and 134 can move relative to each other in the axial direction of the shafts 126 and 126, the contact rollers 134 and 134 as power transmission terminals and the power receiving terminals 86a and 86a can be more reliably brought into contact with each other. It can be.

  In the charging device 10 of the embodiment, the slide plate 104 is moved toward the rear frame 26 by the action lever 32 that rotates about the stripper bolt SB provided between the short side portion 32a and the long side portion 32b. The slide bracket 122 is mechanically inverted to project toward the front frame 24, but a plunger that moves integrally with the slide plate 104 is provided, and oil that is compressed as the plunger moves. The movement of the slide plate 104 toward the rear frame 26 is converted into the movement of the slide bracket 122 toward the front frame 24 by applying a compression force of a compression medium such as water, air, or the like to the slide bracket 122. It doesn't matter.

  In the charging device 10 of the embodiment, the action lever 32 is set so that the distance from the stripper bolt SB to the miniature bearing 150 is larger than the distance from the stripper bolt SB to the miniature bearing 112b. The distance from the stripper bolt SB to the miniature bearing 150 is set equal to the distance from the stripper bolt SB to the miniature bearing 150, or compared to the distance from the stripper bolt SB to the miniature bearing 112b. However, it may be set so that the distance up to becomes small.

  In the charging device 10 of the embodiment, the contact rollers 134 and 134 are in contact with the power receiving terminals 86a and 86a in a state where the spring force is urged by the compression springs 130 and 130. However, the contact rollers 134 and 134 have elastic force. If it is possible to contact the power receiving terminals 86a and 86a with the power receiving terminal 134, the compression springs 130 and 130 are not necessarily used, and a well-known pressure generating mechanism that generates oil pressure, air pressure, or the like may be used.

  In the charging device 10 of the embodiment, the contact rollers 134 and 134 are relatively movable in the axial direction of the shafts 126 and 126 via the insulating blocks 132a and 132b. It does not matter even if it does not move relative to the axial direction of 126. In this case, as illustrated in the contactor 20A of the modification of FIG. 16, the shafts 126A and 126A may be arranged in parallel in the same horizontal plane.

  In the charging device 10 of the embodiment, the lithium ion battery LB is charged as the power storage means. However, the power storage means is not necessarily the lithium ion battery LB, and the power storage means is a nickel / hydrogen storage battery or a nickel / cadmium storage battery. It doesn't matter.

  In the charging device 10 of the embodiment, the contactor 20 is installed at the work station, but a charging station dedicated to charging may be provided, and the contactor 20 may be installed there. In this case, when charging the lithium ion battery LB, the automatic guided vehicle 80 may be controlled to go to the charging station.

  In the charging device 10 of the embodiment, the contact portion between the contactor 20 and the inclined portion 84a of the arm 84, and the connecting portion between the slide plate 104 and the slide bracket 122 and the action lever 32 all use miniature bearings 110b, 112b, and 150. However, any members may be used as long as they can slide with each other.

  In the charging apparatus 10 according to the embodiment, the inclined portion 84a of the arm 84 contacts the miniature bearing 110b, and the contact rollers 134 and 134 receive power at a relatively early stage after the slide plate 104 starts to move toward the rear frame 26 side. The micro switch 36 is turned on at an early stage of preparation for charging until the terminals 86a and 86a are contacted. However, the slide bracket 122 is so touched that the contact rollers 134 and 134 are in contact with the power receiving terminals 86a and 86a. When the slide plate 104 is moved to the rear frame 26 side, the micro switch 36 is turned on, or the slide plate 104 is moved to the rear frame 26 side as much as possible. I.e. B Switch 36 may be made an ON state.

  In the above-described embodiments and modifications, the charging device 10 is used for charging the automatic guided vehicle 80. However, the charging device 10 is used for charging a mobile body equipped with power storage means, for example, an electric vehicle or an electric bicycle. It does not matter as what is used.

  As mentioned above, although embodiment of this invention was described using the Example, this invention is not limited to such an Example, In the range which does not deviate from the summary of this invention, it can implement with a various form. Of course.
