A temperature sensor S is provided as a temperature detection means consisting of a thermistor that outputs .

[0023] As shown in FIG. 1, both air pipes 29a and 29b of the air cylinder 27 are 21, and is connected to an air solenoid valve 35 disposed at the bottom of the support column 21. It is connected to an air supply source 37 via an air tube 36.

Ru.

[0024] As shown in FIG. 5, the ground station T is composed of a control device 38 and a charger 39. It is. A charger 39 is connected to the control device 38, and the control device 3 8 includes the ground-side optical communication device 20, the air solenoid valve 35, the power supply line 31, and the sensor. Cord S1 is connected. The ground-side optical communication device 20 is connected to the vehicle-side optical communication device 20. When communicating with the device 10, the automatic guided vehicle 1 stops at a predetermined position of the charging station J. A signal to that effect is output to the control device 38.

[0025] The control device 38 is connected to the ground-side optical communication device 20 so that the automatic guided vehicle 1 can be connected to the charging station. When a signal indicating that J has stopped at the specified position is input, the air on signal is sent to the air solenoid valve. 35 to open the air solenoid valve 35. Air solenoid valve 3 opened 5 supplies air from the air supply source 37 through the air tube 36 and air piping 29a. The air is supplied to the air cylinder 27.

There is. Therefore, when the guide pin 34 is inserted into the guide hole 16, the A charging start signal is output from the vehicle side optical communication device 10 to the ground side optical communication device 20. That will happen.

[0027] When the ground-side optical communication device 20 receives a charging start signal from the vehicle-side optical communication device 10, At the same time, a charging start signal is output to the control device 38. The control device 38 is on the ground side When a charging start signal is input from the optical communication device 20, an on signal is output to the charger 39. Strengthen. When the charger 39 receives an on signal, it starts charging the battery 11. The sea urchin is turning.

[0028] Then, when a predetermined charging time has elapsed, the control device 38 causes the charger 39 to At the same time, the off signal is output via the ground-side optical communication device 20 and the vehicle-side optical communication device 10. Then, a charging end signal is output to the controller C, and the charger 39 charges the battery 11. After stopping charging, the controller C drives the traveling motor 5 to move the automatic guided vehicle 1 through the vehicle. It is designed to return to normal running.

[0029] Now, the temperature detected by the temperature sensor S, that is, the ground side electrode terminal 30a , 30b is output to the control device 38, and when the temperature reaches 100°C, The control device 38 outputs an off signal to the charger 39, and also outputs an off signal to the ground side optical communication device. 20, and also lights up the electrode error lamp 40 to check the surrounding area. It is designed to notify you of an abnormality in the electrode.

[0030] When the off signal is input from the control device 38, the charger 39 Charging of the battery 11 is stopped even though the battery 11 is being charged. Immediately If the temperature of the ground side electrode terminals 30a, 30b reaches 100°C during charging, Charging of the battery 11 is stopped. On the other hand, a charging retry signal is output from the control device 38 to the ground-side optical communication device 20. The charging retry signal is input to the controller C via the vehicle-side optical communication device 10. be done. The controller C that inputs the charging retry signal drives the driving motor 5. The automatic guided vehicle 1 is moved forward, and the ground side electrode terminals 30a, 30b are connected to the vehicle side. The electrode terminals 13a and 13b are spaced apart.

[0031] Furthermore, the controller C connects the ground side electrode terminals 30a and 30b to the vehicle side electrode terminal. After the automatic guided vehicle 1 is stopped for a certain period of time at a position where 13a and 13b are separated, the automatic guided vehicle 1 is The vehicle 1 is moved backwards, and the vehicle side electrode terminals 13a, 1 are connected to the ground side electrode terminals 30a, 30b. 3b is connected to charge the battery 11 again. Next, we will explain the operation of the automatic charging device for automatic guided vehicles configured as described above. I will clarify.

[0032] First, the operation of the automatic charging device during normal charging will be explained. In FIG. 5, the automatic guided vehicle 1 normally follows a traveling route on which an electromagnetic guide line 2a is laid. When the vehicle is traveling and the mark sensor 8 detects the operation mark 3a, the controller C Based on the detection signal, the arrangement pattern of the operation mark 3a is recognized. And that Determine the operation information (in this case, reverse driving) that corresponds to the arrangement pattern of , the controller C drives and controls the steering motor 4 and the driving motor 5. The automatic guided vehicle 1 is made to spin backwards and turn, and the automatic guided vehicle 1 is branched from the electromagnetic guide line 2a. The charging station J is caused to enter the running route of the lead-in guide wire 2b, that is, the charging station J.

[0033] Next, when the automated guided vehicle 1 moves backwards and enters the charging station J, the automated guided vehicle 1 A vehicle-side optical communication device 10 mounted on the side of the transport vehicle 1 and a ground-side optical communication device 20 face each other. and communicate. At this time, the controller C receives an off signal from the vehicle-side optical communication device 10. input the number to stop the driving of the steering motor 4 and driving motor 5, and leave the vehicle unattended. The transport vehicle 1 is stopped at that position.

[0034] On the other hand, the ground-side optical communication device 20 informs the control device 38 of the ground station T that the automatic guided vehicle 1 is in the charging stage. It outputs a signal indicating that the station J has stopped at a predetermined position, and turns on the air switch of the control device 38. The air solenoid valve 35 is opened based on the signal, and the piston rod 27a is opened unattended. Projects toward the transport vehicle 1 side. As shown in FIG. 4, a guide provided protruding from the ground-side electrode bracket 32 The pin 34 is inserted into the guide hole 16 of the automatic guided vehicle 1 and the limit switch 17 is turned on. The button works. At this time, even if there is a slight deviation in the stopping position of the automatic guided vehicle 1, The upper electrode bracket 32 is supported by a pin 33 and an arm support member 24. Therefore, vertical and horizontal movements are allowed by sliding of the pin 33 and arm support member 24. .

[0035] As the limit switch 17 turns on, the controller C turns on the vehicle side light. A charging start signal is sent to the control device 38 via the communication device 10 and the ground-side optical communication device 20. The control device 38 outputs an on signal to the charger 39. And full From the electric appliance 39 to the power supply line 31, the ground side electrode terminals 30a, 30b and the vehicle side electrode end Power is supplied to the battery 11 through the terminals 13a and 13b, and the Charging will start. When the predetermined charging time has elapsed, an off signal from the control device 38 is activated. When charging of the battery 11 is completed, the air solenoid valve 35 is closed. to contract the piston rod 27a.

[0036] Due to the contraction of the piston rod 27a, the vehicle side electrode terminals 13a, 13 The ground side electrode terminals 30a and 30b are separated from b, and the ground side optical communication is controlled by the control device 38. A charging end signal is output to the controller C via the device 20 and the vehicle side communication device 10. Then, the automatic guided vehicle 1 moves forward. Then, the operation mark is detected by the mark sensor 8. 3b, the controller C detects the operation mark 3b based on the detection signal. The operation information (in this case, forward spin turn travel) is determined, and the automatic guided vehicle 1 is set to forward speed. and return to the traveling route of the electromagnetic induction wire 2a again.

[0037] Therefore, the above operation is repeated and the battery 11 of the automatic guided vehicle 1 is charged. . Subsequently, the vehicle side electrode terminals 13a, 13b or the ground side electrode terminals 30a, 3 If charging is performed with dust or dirt generated in the factory attached to 0b, both The contact resistance between the electrode terminals increases, and the temperature of both electrode terminals becomes higher than during normal charging as described above. Rise. Then, the ground side electrode terminals 30a, 3 detected by the temperature sensor S When the temperature of 0b reaches 100°C, the control device 38 indicates that the predetermined charging time has elapsed. Even though there is no charger, an off signal is output to the charger 39 and at the same time the ground side optical communication A retry signal is output to the device 20, and the electrode abnormality lamp 40 is further turned on.

[0038] Therefore, charging of the battery 11 is stopped, and the control device 38 20 and the vehicle-side optical communication device 10, a retry signal is output to the controller C. Ru. Controller C, which has input the retry signal, drives the traveling motor 5 to drive the vehicle. A position where both side electrode terminals 13a, 13b are separated from ground side electrode terminals 30a, 30b The automatic guided vehicle 1 is stopped running until the point.

[0039] Then, the controller C causes the automatic guided vehicle 1 to travel backwards and again The terminals 13a, 13b are connected to the ground side electrode terminals 30a, 30b. At this time, the control The control device 38 outputs a charging signal to the charger 39, so that the battery 11 is not charged. is started again. However, the temperature of the ground-side electrode terminals 30a and 30b also increases. When the temperature reaches 100°C, a retry signal is output from the control device 38 as described above. , the controller C stops the automatic guided vehicle 1 until the position where both electrode terminals are separated. make it stop

[0040] Therefore, by repeating the above operation, dust and dirt adhering to both electrode terminals can be removed. Debris etc. fall off from both electrode terminals, and the battery is removed with the contact resistance between both electrode terminals reduced. The battery 11 is charged. Then, when the predetermined charging time has elapsed, The vehicle returns to the running route along which the electromagnetic induction wire 2a is laid in the same way as during normal charging. As detailed above, according to the automatic charging device of this embodiment, the ground side electrode bracket By disposing the temperature sensor S on the ground side electrode terminals 30a and 30b, temperature can be measured. Therefore, the vehicle side electrode terminals 13a, 13b and the ground Dust, etc. adheres to the side electrode terminals 30a and 30b, increasing contact resistance and causing damage to both terminals during charging. When the electrode terminal generates heat and its temperature reaches 100°C, the ground side electrode terminal 30a, In order to separate the vehicle side electrode terminals 13a and 13b from 30b, plating is performed due to heat generation. Peeling and deformation of the ground-side electrode bracket 32 can be prevented.

[0041] Further, the retry signal causes the automatic guided vehicle 1 to continuously operate the vehicle side electrode terminals 13a, 1 3b and the ground-side electrode terminals 30a, 30b are separated from each other by repeating automatic travel. This eliminates the need for retry work by workers and reduces line downtime on assembly lines, etc. It is possible to shorten the time and reduce personnel costs. The present invention is not limited to the above-mentioned embodiments, and may be modified without departing from the spirit of the invention. For example, the following configuration can be used within a certain range.

(2) In the above embodiment, the temperature sensor S as a temperature detection means has a ground side electrode terminal. 30a, 30b side to detect the temperature of the ground side electrode terminals 30a, 30b. , this is arranged on the vehicle side electrode terminals 13a, 13b side, and the vehicle side electrode terminals 13a, 1 3b is detected, and controller C outputs a retry signal based on the temperature value. It may be configured to force the

[0043] (3) In the above embodiment, the temperature of the ground side electrode terminals 30a, 30b is 1 of the set temperature. When the temperature sensor S as a temperature detection means detects that the temperature has reached 00℃, From the control device 38 as a charging stop means of the station T to the controller C of the automatic guided vehicle 1 A retry signal is output, the automatic guided vehicle 1 moves forward, and the ground side electrode terminal 30a, 30b and the vehicle side electrode terminals 13a, 13b are separated, but this ground side electrode terminal 30a, 30b and the vehicle-side electrode terminals 13a, 13b when the automatic guided vehicle 1 is running. Alternatively, the piston rod 27a may be contracted. stomach.

[0044] (4) In the above embodiment, the temperature detected by the temperature sensor S as the temperature detection means is When the set temperature of 100°C is reached, the control device 38 as a charging stop means , outputs an off signal to the charger 39 and at the same time outputs a retry signal to the controller C. However, the set temperature may be changed arbitrarily. (5) In the above embodiment, when a predetermined charging time has elapsed from the start of charging, that is, when the battery When charging of the battery 11 is completed, the automatic guided vehicle 1 pulls into the charging station J. The guide line 2b was returned to the running route where the electromagnetic guide line 2a was laid, but this Based on the charging voltage of the battery 11, etc., the electromagnetic induction wire 2a is placed on the running route.
