Abstract

PURPOSE:To enable the generation of an enough external magnetic field for coupling even if the package case is made of a ferromagnetic material such as iron by forming each magnetic core section of the respective inductive coupling coils so that the cross section thereof is shaped in an 'E'-letter. CONSTITUTION:The alternating current induction field due to the alternating current flowing through a partial winding 11E of a coupling coil 11A on the write/read device side is induced in a secondary winding 13 of a coupling coil 11 on the memory module side by relativity of the two coupling coils 11, 11A; however, since the cross section of each magnetic core 12, 11B of the two opposed coupling coils 11, 11A is shaped in an 'E'-letter, an external induction field can sufficiently be generated even if a package case is made of iron. As a result, even if the coupling coils 11, 11A are somewhat shifted in position, data or the power supply can positively be transmitted to the memory module side.

(Industrial Application Field) The present invention relates to a magnetic inductive coupling device for transmitting and receiving signals and power supply between a storage module and a writing/reading device in a non-contact manner. (Conventional device) Conventionally, as this type of magnetic inductive coupling device, for example, the seventh
There is something like the one shown in the figure. In FIG. 7, 1 is a storage module having, for example, a non-volatile memory, and 2 is a read/write device that writes and reads data between the storage module 1 and an external unit. A transmission inductive coupling coil 3 is installed on the end face of the write/read device 2.
A magnetic core 4 of this coupling coil 3 is formed in a horse-shaped shape, and a primary winding 5 is wound around the magnetic core 4. -The next winding 5 is supplied with a constant frequency AC signal (
An alternating current magnetic field is generated in the magnetic core 4 by the -order winding 5. On the other hand, on the end face of the storage module 1 side, a receiving inductive coupling coil 6 is arranged opposite to the transmitting inductive coupling coil 3, and the magnetic field 7 of this coupling coil 6 is also formed in a horse-shaped shape. At the same time, a quadratic winding 8 is wound around the magnetic field 7. Therefore, in a state where the storage module side write/read device 2 is aligned, the alternating current induced magnetic field generated in the negative side magnetic field 4.7 is transferred to the secondary winding between the two magnetic fields 4.7. 8, and receiving this AC induced magnetic field, an AC induced voltage is generated in the secondary winding 8. The AC induced voltage of the secondary winding 8 is converted into a signal of a predetermined frequency by a demodulation means, and is stored in a nonvolatile memory within the storage module 1. In addition, when taking out the AC induced voltage generated in the secondary winding B as a power source, this AC induced voltage is input to the rectifying and stabilizing power supply circuit, and after being rectified to DC, each circuit section of the memory module 1 is supplied with DC voltage. It is supplied as the power supply voltage. (Problem to be solved by the invention) However, such

[In the conventional magnetic induction coupling device J3, a horse-shaped 1A was used as the magnetic '-137 of the magnetic coupling nidoyl, so the horse-shaped A was stored in a ferromagnetic package case made of iron or the like. In this case, the magnetic flux leaks into the iron package case and can generate a sufficient external magnetic field. The case should be made of aluminum or non-magnetic material such as Plus Deck.
In the binding 4 of body b (1J, reverse -1 In this case, severe 41: When using condition -C, a new problem arises that the case is on the verge of breakage, 7 (Solve the problem) The present invention has been made in view of the above-mentioned conventional problems.Inductive coupling =] Even if the package case in which the coil is housed is made of ferromagnetic material such as iron, it is possible to sufficiently achieve coupling. An object of the present invention is to provide a magnetic inductive coupling device capable of generating an external magnetic field.In order to achieve this object, the present invention provides a storage module for storing various data, and a continuous write device that writes data and reads data;
In a magnetic inductive coupling device for supplying power and writing/reading data between the storage module and the writing/reading device in a non-contact manner via inductive coupling coils arranged relative to each other on the storage module side and the writing/reading device side, each inductive coupling coil Each magnetic core portion is formed so that its cross section is [shaped]. (Function) In the present invention having such a configuration, the core portion of the inductively coupled coil is a pot lower type with a “shaped” cross section, so the case for housing the coupling coil is made of ferromagnetic material such as iron. It is possible to generate a sufficient external magnetic field for coupling even when using an external magnetic field for coupling, and since the front surface is point symmetrical, the signal and power supply can be reliably generated even if the relative position of the coupling field is slightly shifted. Moreover, since the case is made of iron, it is highly reliable and will not be damaged even if it is hit by an object. (Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 (A>(B) to FIG. 2(A) and (B) are diagrams showing one embodiment of the present invention. First, the configuration will be explained. In FIG. 1 (A>), 11
is an inductive coupling coil that performs non-contact coupling for transmitting and receiving power and signals between the storage module and the writing/reading device. (See Fig. 1 (B)).The magnetic field 12 is of a pot lower type and includes a cylindrical portion 12A and a cylindrical portion 12B protruding from the center of the bottom wall of the cylindrical portion 12A. The winding 13 that winds the cylindrical portion 12B is housed in the cylindrical portion 12A. In addition, the magnetic core 12
A pair of notches 12C are formed in the respective notches, and the windings 13 are respectively drawn out to the outside via these notches 12C. In addition, 11A in FIG. 1(B) is the other inductive coupling coil 11 that is disposed opposite to the one inductive coupling coil 11 with a predetermined gap L, and one coupling coil 11 is used for reception, for example, and the other coil 11 is used for reception. The combination file 11A is for transmission. Next, 14 in FIGS. 2(A) and 2(B) is a package case containing a storage module, and this case 14 is made of a ferromagnetic material such as iron. This case 14 has two perfect circular openings 15.1, large and small.
6 are formed respectively, and a large receiving inductive coupling coil 11 disposed opposite to the transmitting inductive coupling coil 11A of the writing/reading device is placed in one large opening 15, and a receiving inductive coupling coil 11 is placed in the other small opening Inside the section 16, there is a small transmitting inductive coupling coil 1 arranged opposite to the receiving inductive coil on the write/read device side.
7 are stored respectively. That is, these receiving inductively coupled coils 11 and transmitting inductively coupled coils 16 are connected to each other within each opening 14.15 of its cylindrical portion 12B. 17A, -Next or secondary winding 17B, 13 and cylindrical part 1
2A and 17C are arranged facing each other in an exposed state. In FIG. 2(B), 18 indicates a CPU provided on the printed circuit board 19, and 20 indicates a nonvolatile memory also provided on the printed circuit board 19. Next, the effect will be explained. When the storage module is aligned with the writing/reading device, the receiving inductively coupled coil 11 having the pot-type magnetic core 12 has a pot-type magnetic core 11B.
The transmitting inductively coupled coil 11A is arranged relative to the transmitting inductively coupled coil 11A with a predetermined gap L (see FIG. 1 (B>).The gap L can be increased as the load is lighter; currently, it is 5 mm. In this case, the alternating current induced magnetic field due to the alternating current flowing through the primary winding 11E of the coupling coil 11A on the write/read device side is
A is induced in the secondary winding 13 of the coupling coil 11 on the storage module side, but in this embodiment,
Two opposing coupling coils 11. Each magnetic core 1 of 11A
Since each of 2.11B is formed to have an E-shaped cross section, a sufficient external induced magnetic field can be generated even if the package case 14 is made of iron. Therefore, by receiving this induced magnetic field, it is possible to sufficiently generate an AC induced voltage in the secondary winding 13, and as a result, the coupling coil 11, '11A
Data or power can be reliably transmitted to the storage module even if there is some misalignment. Further, since the case 14 is made of iron, it will not be damaged even if it is hit by an object, and the reliability of the device is extremely high. Next, an example in which the present invention is applied to a data processing device of an FA system used for automatic replacement of workpieces by a machining center will be described with reference to FIGS. 3 and 4. In FIG. 3, reference numeral 21 indicates an automatic tool changer (AT) that automatically exchanges processing tools in a machine tool such as a machining center 22.
C>, 23 is an automatic pallet changing device (APC>) that automatically changes the workpiece 25 mounted on the pallet 24, and these automatic tool changing device 21 and automatic pallet changing device 2
3 are combined to form a factory automation system aimed at unmanned machining operations. In this system, during unmanned operation such as at night, the prepared pallet 24 is transported by an unmanned carrier 27 to the automatic pallet exchange device 23 by mounting a workpiece 25 on the pallet yard 26 and exchanged with a processed pallet 25. The workpieces 25 mounted on pallets 24 prepared one after another are automatically machined by a machining center 22, and the machining tools are automatically replaced by an automatic tool changer 21. In addition, in this system, a storage module 331 having a non-volatile memory that can be replaced externally in response to electrical signals such as an EEPROM is installed in the bullet 24, so that it can be installed in the door 1-24 itself. The dark power supply between this memory 7Dicor 31 and the writing/reading device 32 and the reading/writing of data are performed by the inductive coupling of the above-mentioned Botni] Alive's Ile 11.11A. The arrangement allows for non-contact operation. That is, in FIG. 4 (32), the writing/reading device 32 transfers data from the NC-tape to the serial interface 3.

Using the circular magnetic field shown in Figure 1, the width in the minor axis and short side direction is narrower than that of iJb. In addition, the electric induction force can be changed in each of the long axis direction, the short axis direction, or the long side direction, the short side direction. When moving, if the direction of movement is the same as the long sleeve direction, an elliptical core (or rectangular core) can transmit the guiding force over a longer distance than a circular core, so relative movement due to a relatively high relative speed is possible. (Effects of the Invention) As explained above, according to the present invention, as a connection between a storage module and a writing/reading device for power supply and signal transmission/reception, Since a pot core type inductive coupling coil is used, a sufficient external magnetic field for coupling can be generated even if a case made of iron is used to house the inductive coupling coil, and the relative positioning of the inductive coupling coil can be made slightly smaller. It is possible to reliably transmit signals and power even if it is misaligned.Also, since the case is made of iron, it will not be damaged even if it is hit by an object.
Reliability is extremely high.
