Description

[Detailed description of the invention] This invention relates to an electromagnetic coupler device that can be used to attach and detach cable lines as needed to movable bodies such as trolleys that reciprocate on short distance tracks in factories, port cargo handling facilities, etc. It is something.

There is no need to wait for examples of autonomous driving to quickly and easily attach and detach couplers to enable the supply of electricity, energy, hydraulic pressure, etc. from facilities on the ground to trolleys that move between fixed points depending on the driving situation. This is extremely important.

Therefore, the present invention was developed in view of the above points, in which a power feeding coupler elevating device is arranged at a predetermined position on the ground side, a power receiving coupler is installed on the trolley, and as the elevating device rises, the power feeding coupler is connected to the power receiving coupler. an electromagnet on one of the opposing parts of the power feeding coupler and the lifting device and a magnetic material on the other) and an electromagnet on one of the opposing parts of the power feeding coupler and the power receiving coupler on the other side. It is characterized in that a magnetic body is provided respectively, and when one electromagnet is excited, the other electromagnet is demagnetized, and a power supply coupler is attracted to either the lifting device or the power reception coupler. The reason for this is that the power supply coupler can be quickly attached to and detached from the power reception coupler on the trolley using the magnetic force of the electromagnet.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

The power supply coupler lifting device 1 installed at a predetermined position on the ground side is installed so that a rod 3 with a pedestal 2 attached to its tip is raised and lowered in the vertical direction by a built-in lifting motor. A magnetic body 4 is provided.

A power receiving coupler 6 installed on a trolley 5 that moves between fixed points is equipped with a compression spring 8 inside an outer frame T provided on the trolley 5 and opened at the bottom.
A magnetic body 10 is provided on the lower surface of the outer frame 7 while suspending and supporting the connector 9 which is urged downward at the outer frame 7 .

In the power supply shift 11, a connector 12 that contacts the connector 9 is provided on the upper surface of the holder 13, and electromagnets 14 and 15 corresponding to the magnetic bodies 4 and 10 are provided on the lower and upper surfaces of the holder 13, respectively. When the other electromagnet is energized, a circuit connection is made so that the other electromagnet is demagnetized, and a power supply line is connected.

Next, the operation of the electromagnetic coupler device configured as described above will be explained.

Although electromagnets are provided in each case, the present invention is not limited thereto, and it goes without saying that the electromagnets may be provided in the facing portion of the power receiving coupler 6 facing the power feeding coupler 11 or the pedestal 2.

Since the power supply coupler is detached using an electromagnet in this manner, the device can be made compact, and as a result, it is possible to easily arrange a plurality of devices within the track of the traveling vehicle as necessary.

For example, as shown in FIGS. 4 and 5, each pit 22a to 22 is
E can be operated by moving several trolleys to the E.

That is, in this example, there are three pits 22a on the right side of the traverser 20 and perpendicular thereto.

22b and 22c, and similarly two pits 22d on the left side.
, 22e are arranged, respectively.

Two carts can be moved to the right pits 22a to 22c, and one cart can be moved to the left pits 22d and 22e.

Therefore, two power supply coupler lifting devices 1a and 1b are installed at the entrances of the right pits 22a to 22c, and one power supply coupler lifting device 1c is installed at the entrances of the left pits 22d and 22e, respectively.

On the other hand, carts 5a + 5b move between each pit.
+5c, 5d are power supply coupler lifting devices 1a, 1
b.

Power receiving couplers 6a, 6b, and 6c are provided corresponding to the power receiving coupler 1c.

That is, two power receiving couplers 5a and (ib) are provided at the right end of each of the carts 5a to 5b, and one power receiving coupler 6c is provided at the left end.

Therefore, when the parent cart 21 carrying one of the carts moves on the traverser 20 and stops at a fixed position at one of the pit entrances, the power supply coupler lifting devices 1a, 1b, I
c rises, and the power supply couplers 11a, 11b,
11c is the corresponding power receiving coupler 6a, 6
b, 6c, and the cart can move within each pit while receiving power via the power supply line 16.

For example, as shown in FIG. 5, the cart 5a on the pit 22a connects the power feeding coupler 11a of the power feeding coupler lifting device 1a of the pit 22a with the power receiving coupler 6a, and the cart 5b also connects the power feeding coupler 11a to the power receiving coupler 6a. A power supply coupler 11b of the device 1b is coupled to a power reception coupler 6b.

Further, the cart 5d above the pit 22e connects the power supply coupler 11c of the power supply coupler lifting device 1c of the pit 22e to the power reception coupler 6c.

In this way, by installing an appropriate number of lifting devices for power supply couplers in each pit c and providing corresponding power receiving couplers on the carts, it is possible to move an appropriate number of carts on the traverser to each pit. becomes.

As described above, the present invention utilizes the attraction force due to electromagnetic force, so even a small coupler device can generate sufficient attraction force instantly.

Furthermore, since it can be attached and detached very easily and quickly, it is suitable for remote control and automatic operation, and is a useful device that can be used not only for electric couplers but also for fluid couplers such as air and hydraulic couplers.
