[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic charging device for an automated guided vehicle used to charge a battery mounted on the automated guided vehicle.

[0002]

[Prior art]

 Since the automated guided vehicle travels using the battery installed in it as an energy source, the battery must be charged every time the vehicle travels a certain distance. An automatic charger is used to charge the battery. There are two types of automatic charging devices for automated guided vehicles: one that charges when the automated guided vehicle is stopped and one that charges while the vehicle is running.

The latter type of automatic charging device for an automated guided vehicle is shown in FIGS. 3 (a) and 3 (b). In the figure, 1 is an automated guided vehicle, 10 is a guided vehicle main body, 2 is wheels, 11 is a battery, and 3 is an automatic charging device. The structure of the automatic charging device 3 is shown in FIGS. 4 (a) and 4 (b). As shown in the figure, a pair of parallel plate-shaped contactors 6 are mounted on a base 5 projecting from the floor surface 4, while the lower part of the automated guided vehicle 1 is in sliding contact with the upper surface of each contactor 6. A current collector 8 is attached via a base 7. Then, in order to prevent dust from intervening between the contactor 6 and the current collector 8 to cause improper conduction, brushes 9 are provided in front of and behind the current collector 8 in combination with the base 7.

The wiring from the contactor 6 to the power supply is as shown in FIG. A recess 10 is formed on the floor surface 4 in the middle in the direction in which the base 5 extends, and a groove 11 is formed in a direction perpendicular to the direction in which the base 5 extends from the recess 10. The base 5 is connected to the floor surface 4 via bolts 12, and the contactor 6 is connected to the base 5 via set screws 13 penetrating the base 5. The other end of the cable, one end of which is connected to a power source (not shown), is guided to the recess 10 through the groove 11, and the terminal 15 attached to the other end of the cable is coupled to the set screw 13 through the nut 14. Has been done.

In such an automatic charging device for an unmanned guided vehicle, when a photoelectric sensor or the like detects that the unmanned guided vehicle 1 has arrived at the charging zone in which the contactor 6 is provided, the contactor 6 and the power source are connected to each other. The provided open / close switch is turned on, and the battery is charged via the contactor 6 and the current collector 8. Since the contactor 6 is long, the current collector 8 makes sliding contact with the contactor 6 even when the automatic guided vehicle 1 is running, and the battery can be charged while running. Then, when the photoelectric sensor or the like detects that the automatic guided vehicle 1 has exited the charging zone, the open / close switch is turned off, the power supply to the contactor 6 is stopped, and the charging is completed.

[0006]

[Problems to be solved by the device]

 However, since the contactor 6 is connected to the terminal 15 of the cable by using the set screw 13 projecting downward of the base 5, the recess 10 and the groove 11 must be formed in the floor surface 4, so that the unmanned transfer is performed. It is troublesome to construct and change the car taxiway because floor construction is required.

Therefore, an object of the present invention is to provide an automatic charging device for an automatic guided vehicle that solves the above problems.

[0008]

[Means for Solving the Problems]

 The structure of the present invention for attaining such an object is such that it is detachably fixed to the floor surface and is coupled to the upper surface of the base in parallel with the base formed of an insulating material. A pair of contacts, in which the current collectors that are electrically connected to the battery on the carrier are in sliding contact, a contact space formed below the contactor in the base, and a space formed in the base from the connection space in the direction perpendicular to the contactor. It is characterized by comprising a wiring space and a cable which is arranged in the wiring space and has one end connected to a power source and the other end connected to a contactor in the connection space.

[0009]

[Operation] When the automatic charging device is attached to the floor, the cable terminals are connected to the contactor in the connection space in the base without forming a recess in the floor, and the cable is connected to the wiring space in the base. The base is coupled to the floor surface with bolts or the like in the state of housing.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

The structure of the automatic charging apparatus for the automatic guided vehicle according to the present invention is shown in FIGS. As shown, a base 16 is formed of an insulating material, and a pair of contactors 17 and auxiliary contactors 18 are arranged in parallel with each other along the direction in which the base 16 extends. Then, each contactor 17 arranged on the base 16 is coupled to the base 16 via set screws 19 arranged at both ends and in the middle thereof, and the auxiliary contactor 18 is set screw 19 arranged at both ends. Is coupled to the base 16 via. Two narrow grooves 20 are formed between the pair of contactors 17 on the base 16, and the bolts 21 are provided between both ends of the base 20 and between the grooves 20. The base 16 is attached to the floor surface 22.

In order to connect the contactor 17 to a power source (not shown), it is configured as follows. As shown by a broken line in FIG. 2A, a connection space 23 is formed below the pair of contactors 17 and the auxiliary contactor 18 by notching through the base 16. Further, wiring spaces 24a, 24b, 24c for connecting the connection space 23 and the outside of the base 16 are formed in the base 16. Then, a pair of contactors 17 are connected to a power source via a cable (not shown), and the charging stop time is detected by mounting the collector 8 of the automatic guided vehicle on both the contactors 17 and the auxiliary contactors 18. In order to do so, the auxiliary contactor 18 and the like are connected. The connection between the terminal 26 attached to the end of each cable and the contactor will be described with reference to FIG. A terminal 26 is inserted into a mounting screw 25 penetrating the contactor at the position of the connection space in each contactor, and a nut 29 is screwed into the mounting screw 25 via a flat washer 27 and a spring washer 28. The respective cables are guided to the side of the base 16 via the connection space 23 and the wiring spaces 24a, 24b, 24c.

Next, the operation of the automatic charging device for the automatic guided vehicle will be described. In order to attach the automatic charging device to the floor surface, after attaching the terminal 26 at the tip of each cable to the pair of contactors 17 and the auxiliary contactors 18 via the attachment screws 25, the cables are connected to the connection space 23 and the wiring spaces 24a, 24b, It goes out to the side of the base 16 through 24c. After that, the base 16 is placed on the floor surface, tap holes are formed on the floor surface, and the bolts 21 are turned and screwed into the tap holes, whereby the base 16 is fixed to the floor surface. The cables extending from the sides of the base 16 are connected to predetermined parts, respectively. Since it is not necessary to form a recess for laying the cable on the floor as in the conventional case, the work of laying the automatic charging device can be performed very easily.

Although the present embodiment shows the case where the auxiliary contactor is provided in addition to the pair of contactors, the presence or absence of the auxiliary contactor does not matter.

[0015]

[Effect of device]

 As can be seen from the above description, since the automatic charging device for an automatic guided vehicle according to the present invention forms the connection space for connecting the terminal of the cable and the wiring space for wiring the cable in the base, As described above, the automatic charging device can be installed without performing the work for forming the concave portion for the cable wiring on the floor surface. Also, the work can be easily performed when changing the taxiway of the automatic guided vehicle.
