Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a cross section of a transport device 1 according to an embodiment of the present invention.

As shown in FIG. 1, the transport device 1 includes a nonmagnetic tube 11, an internal moving body 12, a wheel 13, a leaky coaxial cable 14, a power transmission electrode 15 as an inner conductor, a power reception electrode 16, and an external movement. The body 17, the pallet 18, the inner guide 19, the outer guide 20, the inverter 21, the bus bar 22, the magnet M, the rail 31, and the installation base 32 are included.
The internal moving body 12 moves in the non-magnetic tube 11 as an outer conductor fixed to the installation base 32 on the rail 31 by obtaining electric power with an electric field coupling type electrode pair and driving the wheel 13. The transport device 1 can perform bidirectional communication with an external system using the leaky coaxial cable 14.

Although not shown in the figure, the moving body (the internal moving body 12 and the external moving body 17) includes a linear encoder, and therefore can grasp its own position. Moreover, based on position data, it can move, communicating between an external system or between adjacent mobile bodies. Here, since the internal moving body 12, the power transmission electrode 15 as the inner conductor, and the leaky coaxial cable 14 are contained in the sealed structure, they are not affected by the external environment (dust, water, etc.).
In addition, when the leakage of electromagnetic waves is not taken into consideration, a structure that does not have a sealed structure (for example, a structure in which the lower part of the nonmagnetic tube 11 is opened) can be used. Thereby, maintenance can be performed efficiently.

A magnet M is mounted on the internal moving body 12. Even when surrounded by the nonmagnetic tube 11, a magnetic field can be formed outside the nonmagnetic tube 11. An external moving body 17 supported by a wheel 13 is disposed outside the nonmagnetic tube 11. In addition, since the magnet M is mounted on the external moving body 17, the polarity is such that attractive force is generated between the external moving body 17 and the magnet M mounted on the internal moving body 12.
Thereby, the external moving body 17 also moves in accordance with the movement of the internal moving body 12.
Although not shown, when the upward force is dominant by the magnet M, the wheel 13 can be attached to the upper side of the internal moving body 12.

The external moving body 17 is loaded with a pallet 18 on which luggage can be placed. For this reason, the pallet 18 can be transferred between the external moving bodies 17.
In addition, as another characteristic in the cross section of the conveyance apparatus 1 which concerns on one Embodiment of this invention of FIG. 1, it is as showing in FIG.

FIG. 2 is a diagram showing a plane of the transport device 1 of FIG.

FIG. 2 shows a plan view of the internal moving body 12 and the external moving body 17. Further, the positional relationship among the nonmagnetic tube 11 and the leaky coaxial cable 14 and the internal moving body 12 and the external moving body 17 is shown.

FIG. 2A showing a plan view of the internal moving body 12 and FIG. 2B showing a plan view of the external moving body 17 are shown on the same rail 31 and corresponds to the cross-sectional view of FIG. This is compared with FIG. In FIG. 2, the positional relationship of each magnet M, wheel 13, power receiving electrode 16, etc. is shown.

The power transmission electrode 15 as the inner conductor extends in parallel along the rail 31 although not shown in FIG. 2.
Further, FIG. 2 shows a power transmission coil 23 and a power receiving coil 24 that transmit power from the internal mobile body 12 to the external mobile body 17, and communication between the internal mobile body 12 and the external mobile body 17. An enabling communication unit 25 is provided. It is considered that the electric power transmitted from the internal moving body 12 to the external moving body 17 is mainly used for transferring (including rotating) the pallet 18 and operating the sensor.

By adopting such a system configuration, the power transmission system is hermetically sealed outside the entire rail 31 including the external moving body 17. For this reason, it is only necessary to worry about dust on the rail 31 and not to worry about water and dust around the electrode.
Furthermore, since electric power is transmitted also to the external mobile body 17, since communication is possible, it is easy to utilize as an IoT device.

In addition, as another characteristic in the figure which shows the plane of the conveyance apparatus 1 of FIG. 1 of FIG. 2, it is as showing in FIG.

FIG. 3 is an image diagram of the transport device 1 of FIG.

As shown in FIG. 3, the internal moving body 12 is driven by a motor. The external moving body 17 follows the internal moving body 12 by magnetic coupling with the internal moving body 12. Moreover, the external moving body 17 delivers and receives the pallet 18 between other external moving bodies as needed. Note that power transmission from the internal moving body 12 to the external moving body 17 and communication between the internal moving body 12 and the external moving body 17 are performed through the nonmagnetic tube 11.
Details are shown in Table 1.
As shown in Table 1, the nonmagnetic tube 11 has options A1 to A5.

Here, considering the non-leakage of electromagnetic waves, the nonmagnetic tube 11 is preferably a metal.
However, even if the options A2 to A5 are adopted, the radiated electromagnetic wave can be reduced by using a method such as feathering the electrodes.

As shown in Table 2, there are options B1 to B6 for the energy transmission means.

As shown in Table 3, there are C1 to C6 options for energy transfer means.

Although FIG. 1 shows the electric field coupling method, a magnetic field method, a contact method (trolley method), an electromagnetic wave method, and an acoustic method can be employed. If the rail 31 itself can be vibrated from the outside, a vibration power generation method can also be adopted.

As shown in Table 4, the magnet M used on the internal moving body 12 has options D1 to D3.

As shown in Table 5, there are options E1 to E4 for the magnet M used on the external moving body 17 side.

There is an option of using a permanent magnet, an electromagnet, and a superconducting magnet as the magnet M in the internal moving body 12.
As the magnet M on the external moving body 17 side, a permanent magnet or an electromagnet can be placed and attracted. In particular, in the case of an electromagnet, if it is necessary to remove the magnet, it can be easily separated because it is sufficient to eliminate the magnetism or reverse the magnetic pole.

In the case of a permanent magnet, the energy required for separation can be reduced by mechanically separating the distance between the magnets M.
Further, a ferromagnetic material can be used as the magnet M on the power receiving electrode 16 side. When facing the magnet M, it is necessary to always be aware of the polarity of the facing magnet, but in the case of a ferromagnetic material, such consideration is unnecessary.

When a superconducting magnet is used as the magnet M, since it can be fixed by pinning using a type 2 superconductor in particular, there is an advantage that it can be held upside down.
Further, by combining a permanent magnet and an electromagnet, it is usually possible to use both a permanent magnet and an electromagnet in order to generate a stronger magnetic field during initial movement using only the permanent magnet. Furthermore, when it is desired to break the magnetic coupling, a method of reducing the magnetic force to the outside by generating a reverse magnetic field may be adopted.

As shown in Table 6, there are options F1 to F8 as the driving method of the internal moving body 12 when power is supplied to the external moving body 17.

As shown in Table 7, there are G1 to G7 options for driving the internal moving body 12 when supplying power to the external moving body that supplies power to the attachment of the nonmagnetic tube 11.

In FIG. 1, the method F1 in Table 6 is shown, but as other methods, methods F2 to F8 or G1 to G7 can be adopted.

As shown in Table 8, there are H1 to H8 options for positioning the internal moving body 12 and the external moving body 17 in the vertical direction (weighting direction).

As the guide method for the horizontal positioning method of the internal moving body 12 and the external moving body 17, there are options I1 to I7 as shown in Table 9.

In FIG. 1, the method of H1 in Table 8 and the method of I1 in Table 9 are adopted, but one method can be selected and combined from H1 to H8 and I1 to I7.

When the nonmagnetic tube 11 is sealed with aluminum or the like, there are options J1 to J5 as shown in Table 10. The method J2 is limited to electromagnetic shielding.

In FIG. 1, the nonmagnetic tube 11 has a structure completely closed with respect to the outside world. The leaky coaxial cable 14 and the wiring connection portion have openings, but are covered by the installation base 32, so that there is no opening outside (see J1 in Table 10).

As shown in Table 11, the communication method between the internal mobile body 12 and the external mobile body 17 has options K1 to K4.

In addition, as another characteristic in the image figure of the conveyance apparatus of FIG. 1 of FIG. 3, it is as showing in FIG.

FIG. 4 is a diagram illustrating a state in which bidirectional communication is performed between the internal moving body 12 and the external moving body 17 constituting the transporting device of FIG. Example).

As shown in FIG. 4, communication between the internal mobile unit 12 and the external mobile unit 17 is made possible by preparing a plurality of slot S rows and a plurality of transmission / reception sets and combining the detector outputs with diversity. If the slot S is filled with a transparent dielectric, the hermeticity can be maintained. These plural slots S row are used for the wall of the nonmagnetic tube 11.

In addition, as another characteristic in the figure which shows a mode that bidirectional | two-way slot row penetration light is performed between the internal mobile body 12 and the external mobile body 17 which comprise the conveyance apparatus 1 of FIG. Is as shown in FIG.

FIG. 5 is a diagram showing the principle of transmitting power between the front and back of the metal shielding plate when the metal shielding plate having a plurality of slots S shown in FIG.

First, a method for transmitting power through the slot S will be described. The method can also be used for communication purposes.

As an existing technology, there is an effect that an electric field excited by a patch antenna can be fed to a microstrip line through a slot S or vice versa. In this case, the principle shown in FIG. 5A is the main one, but here, the electric field coupling power transmission technology through the slot S will be described.

FIG. 5A and FIG. 5B show a case where power is transmitted between the front side and the back side of the electric field coupling electrode through the slot S opened in the metal shielding plate as the nonmagnetic tube 11. . There are two cases as the principle.

The method used for power transmission to the microstrip line described above is shown in FIG. In the case of this method, the current between the electrode A1 and the electrode A2 on the power transmission surface A side flows as a displacement current 41 between each electrode and the metal shielding plate (nonmagnetic tube 11), but the metal shielding plate (nonmagnetic). It flows as a surface current 42 on the tube 11). Since the surface current 42 is present in the slot S, the surface current 42 flows around the left and right. When this surface current 42 flows in a detour, a sharp curve is cut at the end of the slot S, so that a strong magnetic field 51 is generated. Since the magnetic field 51 is generated clockwise and counterclockwise in the opposite direction, a rotating magnetic field is generated in the slot S.

Since this rotating magnetic field is generated when viewed from the back side (the power receiving surface B side) of the metal shielding plate (nonmagnetic tube 11), a current in a direction that cancels the rotating magnetic field is generated. That is, a current in the opposite direction to the power transmission surface A side is generated on the power reception surface B side in FIG. Due to this current, a potential is generated between the electrode B1 and the electrode B2, and power can be transmitted. However, in this case, the phase is delayed by 90 degrees because of the electromagnetic induction phenomenon.
On the other hand, in the case of FIG. 5B, the through-slot surface current 43 becomes a problem. That is, the slot through surface current 43 does not bypass the slot S but passes through the slot S from the electrode A1 to the electrode B1, and the other flows from the electrode B2 to the electrode A2. In the slot S, a current in the reverse direction flows on the opposite surface. In this case, no delay occurs because electromagnetic induction is not used.

In addition, as another characteristic in the figure which shows the principle which transmits power between the front and back of the metal shielding board (nonmagnetic tube 11) which has the slot S of FIG. 4 of FIG. 5, it is as showing in FIG.

Next, the electrode excitation method will be discussed with reference to FIG.
FIG. 6 is a diagram showing an electrode resonance method when power is transmitted through the metal shielding plate (nonmagnetic tube 11) having the slot S of FIG.

FIG. 6A shows a case where an antenna is used. As an antenna in this case, a half-wave antenna with a negligible width can be considered. Among them is a meander antenna.
In this case, the distance between the antenna and the metal shielding plate (non-magnetic tube 11) is slightly separated to function as a standing wave antenna. A voltage distribution 61 in which the end portion has the maximum voltage is generated.
Thereby, the surface current 62 is induced, and electric power is transmitted to the power receiving surface B side by the method shown in FIGS. 5 (a) and 5 (b).

FIG. 6B shows a case where the junction capacity is increased by bringing the electrode close to the metal shielding plate (nonmagnetic tube 11). In this case, a method of connecting resonance inductances in series or a method of parallel resonance can be employed. In the case of series resonance, a large current can be passed and power can be transmitted efficiently.
When the electrodes face both surfaces of the internal moving body 12 and the external moving body 17 with the nonmagnetic tube 11 shown in FIG. 2 interposed therebetween, the metal shielding plate (nonmagnetic tube 11) moves. At this time, the slots S are arranged as shown in FIG.

As shown in Table 12, there are options L1 to L6 for the power transmission method from the internal mobile body 12 to the external mobile body 17.

As shown in Table 13, the package delivery function by the external mobile body 17 has options M1 to M5.

As shown in Table 14, there are N1 or N2 options for the pallet fixing method and the power transmission method of the external moving body 17.

In addition, as another characteristic in the figure which shows the resonance system of the electrode at the time of power transmission through the metal shielding board (nonmagnetic tube 11) which has the slot S of FIG. 4 of FIG. 6, it is as showing in FIG.

FIG. 7 is a diagram showing a method of fixing with an insulating rotating pin 71 as an example of a method of fixing the external moving body 17 and the pallet 18 constituting the transporting device 1 of FIG.

As shown in FIG. 7, when inserting the insulating rotating pin 71 into the insulating elastic receiving portion 73 of the pallet 18, it can be inserted in a state where there is a space (see FIG. 7A). At this time, since the insulating elastic receiving portion 73 is made of an elastic member, the click feeling can be obtained by rotating the insulating rotating pin 71 in the insulating elastic receiving portion 73 (FIG. 7B). )reference). Further, when the rotating electrode 72 and the fixed electrode 74 are opposed to each other, pressure can be applied to bring the rotating electrode 72 and the fixed electrode 74 into close contact (see FIG. 7C).

As an example of a method of fixing the external moving body 17 and the pallet 18 constituting the transporting device 1 of FIG. 1 shown in FIG. As shown in FIG.

FIG. 8 is a circuit diagram when the method of fixing with the insulated rotating pin 71 of FIG. 7 is adopted.

As shown in FIG. 8, by using the counter electrode (the rotating electrode 72 and the fixed electrode 74) as different polarities and utilizing the action / reaction, the rotating electrode 72 and the fixed electrode 74 can be reliably adhered to each other.

7 and 8 are used by a contact method or an electric field coupling method. When used in an electric field coupling method, high reliability can be obtained.
In the contact method, the performance is easily affected by the oxidation state of the interface and the adhesion state of dust. In this method, the friction is always rubbed, so that the performance is easily maintained even in the contact method. However, when acidic and alkaline substances are present in the environment, the electric field coupling type should be used. Although not shown in the drawing, a mechanism that is locked by rotation can be attached in order to prevent the insulating rotation pin 71 from slipping out.

As shown in Table 15, there are options of O1 to O5 for communication between the internal moving bodies 12 and between the internal moving body 12 and the rail 31 (including devices attached to the rail 31).

As shown in Table 16, there are P1 and P2 options for the system in which the rail 31 is a fixed rail (fully sealed rail).

As shown in Table 17, there are Q1 or Q2 options for the system in which the rail 31 is a continuous rail.

As shown in Table 18, the method of R1 can be adopted as the rail transport method by the rail 31.

As shown in Table 19, there are S1 and S2 options for the DC transmission system.

As shown in Table 20, there are options T1 to T6 for the drying method in the rail 31 or the plasma generation between the electrodes. Note that a magnetic field may be applied to the electrode portion when considering the interelectrode plasma.

As shown in Table 21, there are U1 to U3 options for joining the rails 31.

As shown in Table 22, there are V1 to V7 options for the self-diagnosis method.

As shown in Table 23, there are W1 to W4 options for the internal pressure control method.

As shown in Table 24, there are X1 or X2 options for the use of the conduit or rail 31 that runs alongside the rail 31.

In addition, as another characteristic in the circuit diagram at the time of employ | adopting the method fixed with the insulated rotating pin 71 of FIG. 7 shown in FIG. 8, it is as showing in FIG.

By supplying electric energy from the power transmission side electrode plate connected to a power source to the power reception side electrode plate connected to a load, from the power transmission surface side of the nonmagnetic tube to the power reception surface side of the nonmagnetic tube. In contrast, electrical energy is transmitted.

The nonmagnetic tube can be a metal shielding plate.

The connector to which the present invention is applied is
Electric energy can be transmitted by aligning the resonance conditions of the power transmitting side electrode plate and the power receiving side electrode plate in addition to aligning the slot length or in addition to aligning the slot length.

The connector to which the present invention is applied is
A connector used when electric energy is transmitted to the loading unit by an external moving body that carries a loading unit on which a load is placed and moves outside the non-magnetic tube,
A plurality of first electrodes (for example, fixed electrodes 74 in FIG. 7) arranged facing the inside of an insertion hole provided in one of the external moving body and the stacking unit;
A plurality of second electrodes arranged on a side surface of an insertion body (for example, the insulating rotating pin 71 in FIG. 7) provided on a side different from the side on which the insertion hole is provided, of the external moving body and the loading portion. (For example, the rotating electrode 72 in FIG. 7);
With
There is a clearance between the insertion hole and the insert,
When the insertion body is inserted into the insertion hole, the first electrode and the second electrode do not face each other,
When the insert inserted in the insertion hole rotates, the first electrode and the second electrode face each other and come into close contact with each other, thereby enabling conductive connection or capacitive connection with each other.
When a power source is connected to one of the first electrode or the second electrode and a load is connected to the other electrode, a power transmission circuit is formed. Electric energy is transmitted to the other electrode.
As a result, only the mechanical part is exposed to the outside of the nonmagnetic body 11, and the electronic part can be completely hidden inside the nonmagnetic body 11. Since the electronics part can be sealed, it is not affected by the outside world where dust is clogged between the electrodes or water is accumulated. Furthermore, the user does not have to worry about electric shock and can reduce the radiated electromagnetic field.

On the other hand, since long-distance laying, power transmission to the power receiver, movement control, and information exchange are possible, convenience is greatly improved.
Moreover, since it becomes a completely waterproof type, IoT-like benefits can be widely used not only in factories but also in agriculture, livestock farming, fishing, and forestry. Furthermore, it can be extended to simple indoor applications (curtains, automatic doors, etc.) and use in pools.
