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

(Embodiment 1)
1-6 is a figure which shows the food conveying apparatus using the non-contact-type electric power feeder of Embodiment 1 of this invention. FIG. 1 is an explanatory view showing a schematic configuration of the food conveying device, and FIG. 2 is a schematic diagram showing the entire conveying device main body in FIG. 1 ((a) is a top view and (b) is a front view). 3 is an enlarged view of a main part of the food conveying device (cross-sectional view taken along line AA in FIG. 2B), FIG. 4 is a cross-sectional view of the feeder line of the food conveying device, and FIG. 5 is the food conveying device. FIG. 6 is an explanatory view of the magnetic flux passing through the core in the pickup unit.

  The food conveyance device according to the first embodiment is a rice cooking device, and includes a conveyance plate 305 on which the rice cooker 306 is placed, and a drive unit 111 that moves the conveyance plate 305 in the vertical and horizontal directions. 300 and a power feeding device 200 that feeds power to a driving device 111 mounted on the main body 300. The power feeding device 200 includes a power feeding line 100 through which a high-frequency current flows and a core 2 that is inductively coupled to the power feeding line 100. The feeding plate 305 is driven by supplying power to the driving device 111 by the induced electromotive force induced in the pickup unit 1 provided. As shown in FIGS. 2A and 2B, the transport plate 305 has a plurality of upper stages 16 and lower stages 16 disposed at predetermined intervals, and travels on a traveling rail 303 constituting a track. To do. The driving device 111 includes an inverter and a motor, and conveys the conveying plate 305 at a predetermined speed.

  Furthermore, as shown in FIG. 3, a power feeding unit 500 is provided that feeds power for rice cooking to the rice cooker 306 that is placed on the transport plate 305 and travels at a predetermined speed. This power supply unit 500 also includes an AC outlet inverter 501 and an outlet 502, and the induced electromotive force induced in the pickup unit 1 is branched and supplied, so that the rice cooker 106 can be supplied by non-contact power supply. Made. Here, the electric power obtained by the pickup unit 1 for driving the transport plate may be separately supplied by separately providing a power supply line and a pickup unit.

  That is, the food conveyance device according to the present embodiment includes a feed line 100 installed in a loop as shown in FIG. 1, a high-frequency power source 110 that sends a high-frequency current to the feed line 100, and a pickup that is inductively coupled to the feed line 100. Unit 1 and supplies power to the outlet 502 from the pickup unit 1 to the driving device 111 that is a load.

  As shown in FIG. 4A, the power supply line 100 includes a cylindrical inner tube portion 101, a cylindrical outer tube portion 102 disposed outside the inner tube portion 101, an inner tube portion 101, and an outer tube portion. The connecting part 103 that connects the two parts 102 so as to be concentric with each other is formed by coating a conductor integrally formed by bending a metal plate with an insulator 104 made of a synthetic resin molded product having a rectangular tube shape. ing. That is, in a power supply line through which a high-frequency current flows, there is a resistance (high-frequency resistance) due to the skin effect and proximity effect in addition to the electrical resistance of the conductor material (metal plate). By using it for 100, it is possible to reduce the high-frequency resistance and the loss as compared with the cylindrical conductor.

  The power supply line is not necessarily limited to this structure, and the manufacturing method is not only bending, but also metal extrusion or the inner tube portion 101 including the connecting portion 103 in the outer tube portion 102. It can also be manufactured by a method such as press-fitting. As an example, a modification is shown in FIG. This power supply line connects the cylindrical inner tube portion 101, the cylindrical outer tube portion 102 disposed outside the inner tube portion 101, and the inner tube portion 101 and the outer tube portion 102 so as to be concentric with each other. The four conductors 103 are covered with an insulator 104 made of a square tube-shaped synthetic resin molded product.

  The pickup unit 1 includes a core 2, a coil 3, a bobbin 4, a magnetic shield body 5, and a power receiving circuit unit 6. The power receiving circuit unit 6 includes a capacitor that forms a resonance circuit together with the coil 3, a constant voltage circuit that makes the resonance voltage output from the resonance circuit of the coil 3 and the capacitor constant, and the like.

  As shown in FIG. 5, the core 2 has both an inner peripheral surface and an outer peripheral surface formed of curved surfaces (cylindrical surfaces), and has a substantially C-shaped cross section that intersects the axial direction (direction perpendicular to the paper surface). Yes. Here, both end portions 20 of the core 2 facing each other with the opening groove 2a interposed therebetween are cross sections along the axial direction, rather than portions (hereinafter referred to as “body portions”) 21 excluding the both end portions 20 of the core 2. The area is formed large.

  The bobbin 4 is made of a rectangular tube-shaped resin molded product curved in an arc shape, and outer casings 40 are provided at both ends in the axial direction. The core 2 is divided into two body parts 21 at the opposite side of the opening groove 2a, and the end parts of the body part 21 are joined to each other after the bobbin 4 is extrapolated to each body part 21. Thus, the core 2 shown in FIG. 5 is configured. Here, the core 2 has a two-divided structure, but may not be divided.

  The coil 3 is formed by winding a winding having an insulating coating around the bobbin 4 in a single layer. The step between the end portion 20 of the core 2 and the body portion 21 is set to be larger than the diameter of the winding so that the coil 3 does not protrude beyond the end portion 20 of the core 2. Thus, since the coil 3 does not protrude outside the end portion 20 of the core 2, magnetic flux leaking from the end portion of the coil 3 to the outside of the end portion 20 of the core 2 can be reduced.

  The magnetic shield body 5 is formed in a substantially cylindrical shape by a metal magnetic material having a high magnetic permeability, and is extrapolated to the core 2 and the coil 3. However, the magnetic shield body 5 is provided with a groove 5a communicating with the opening groove 2a of the core 2 along the axial direction. The magnetic shield 5 is not essential and may be omitted.

  As shown in FIG. 1, the core 2 has a substantially U-shaped outer section so as to straddle the power supply line 100 from the side, and the core 2 is located on both sides of the power supply line 100 inside the outer structure. A pair of coils are arranged opposite to each other to constitute an electromagnetic pickup. Here, the coil is preferably as close as possible to the feeder line 100. Then, when a high frequency current is supplied from the power source 110 to the power supply line 100, a magnetic field MF is generated and attenuated according to the frequency of the supplied high frequency current around the power supply line 100. As the magnetic flux density changes, an induction current is generated in the coil (electromagnetic induction).

  In the power receiving circuit section 6 shown in FIG. 1, the current generated in the coil in this way is stabilized by a resonance circuit (not shown) in the power receiving circuit section, and then the inverter of the driving device 111 is converted from the constant voltage circuit. Send to. The drive device 111 that drives the travel of the transport plate includes an inverter and a motor, and the inverter converts the current into a direct current and supplies it to the motor. The motor drives the transport plate 305 to travel along the travel rail 303.

  In this way, when a high frequency current flows through the opening groove 2a to the power supply line 100 disposed inside the core 2, as shown in FIG. 6, the high frequency current is formed on a concentric circle centering on the power supply line 100 (see FIG. 1). A magnetic field (magnetic flux φ) is generated, and most of the magnetic flux φ passes through the core 2 along the circumferential direction without leakage.

At this time, a comparative example is shown in FIG. When the inner peripheral surface and the outer peripheral surface of the core 2 ′ are both configured by abutting a plurality of planes as in the usual structure, that is, when the core 2 ′ has a substantially U-shaped cross section, FIG. As shown in the figure, a part of the magnetic flux φ leaks out of the core 2 ′ at the boundary portion (corner portion) between the flat surfaces, but the core 2 in the present embodiment has both the inner peripheral surface and the outer peripheral surface. Since the cross-sectional shape that is formed of a curved surface and intersects the axial direction is substantially C-shaped, the magnetic flux φ that leaks to the outside from the portion other than the opening groove 2a is hardly generated as shown in FIG.
Therefore, compared with the core 2 ′ of the comparative example shown in FIG. 7, the efficiency of power transmission from the feeder 100 to the pickup unit 1 is improved according to the core 2 of the present embodiment as shown in FIG. In addition, the amount of power supply can be increased.

In this way, the rice cooker traveled at a slightly longer cycle than the rice cooking time, and rice and water were set in the rice set unit R1 shown in FIG. 2 or, if necessary, and cooked in the takeout unit R2. Rice is taken out.
In this way, rice can be continuously cooked with good workability, and freshly cooked rice can always be supplied.
Moreover, the rice cooking amount per hour can also be adjusted easily by providing the rice cooker which is not set by the rice cooking set part R1 as needed, or delaying a conveyance period.

  In such a food transport device, since the transport plate is driven by non-contact power feeding, it is possible to always cook rice in a clean atmosphere without generating abrasion powder and maintenance-free. Therefore, workability is extremely good.

  In the present embodiment, both the inner peripheral surface and the outer peripheral surface of the core 2 are formed of curved surfaces, but a modification is shown. For example, only the outer peripheral surface may be formed of a curved surface as shown in the cross-sectional view of the core of the modified example in FIG. 8, or only the inner peripheral surface as shown in the cross-sectional view of the core of another modified example in FIG. The core 2 of any shape may have an opening as compared with the conventional core 2 ′ in which the inner peripheral surface and the outer peripheral surface are both configured by abutting a plurality of planes. It is possible to reduce the magnetic flux φ leaking to the outside from a portion other than the groove 2a. However, it is clear that the power transmission efficiency of the core 2 of the present embodiment is the highest with respect to these two types of cores 2.

  By the way, in the case where one of the two feed lines 100 going back and forth to the high frequency power supply 110 is arranged inside the core 2 and the other feed line 100 is arranged in the vicinity of the pickup unit 1. The magnetic flux generated around the other power supply line 100 cancels out with the magnetic flux φ passing through the core 2, and as a result, the power transmission efficiency of the pickup unit 1 may be reduced. On the other hand, in the present embodiment, since the core 2 and the coil 3 are covered with the magnetic shield body 5 and magnetically shielded, the magnetic flux φ passing through the core 2 as described above is an external magnetic field (magnetic flux). Can be prevented, and as a result, loss can be reduced.

  Further, in the present embodiment, the opening groove 2a is provided in the core 2 of the pickup unit 1 so as to be easily attached to and detached from the power supply line 100. In this opening groove 2a (gap), a magnetic circuit is provided. This greatly increases the magnetic resistance. Therefore, in the present embodiment, both end portions 20 and 20 of the core 2 facing each other across the opening groove 2a are formed to have a larger cross-sectional area along the axial direction than the body portion 21 excluding the both end portions 20 of the core 2. Thus, the magnetic resistance at both ends 20 and 20 of the core 2 is relatively reduced as compared with the body portion 21, and the magnetic flux leaking out of the core 2 from the opening groove 2a is reduced.

  Furthermore, when a coil is formed by winding multiple windings, the high frequency resistance of the winding may increase due to the proximity effect, which may reduce the efficiency of power transmission. Therefore, in the present embodiment, by forming the coil 3 by winding a single layer of the winding around the core 2, the high frequency resistance of the coil 3 is reduced as compared with the case where the winding is wound in multiple layers, and as a result The transmission efficiency can be improved.

As described above, according to the food conveying device of the present invention, since it is a non-contact power feeding method, power can be fed without a sliding portion, and the drive device is driven by the induced electromotive force induced in the pickup portion 1. By supplying power, the conveying plate is driven, so that no wear powder is generated, and the maintenance frequency can be reduced in a clean environment.
Moreover, also about the electric power feeding for rice cooking, electric power feeding can be performed very efficiently by non-contact electric power feeding.

In this non-contact power supply device, it is necessary to control the distance between the power supply line through which the high-frequency current flows and the pickup unit with high accuracy, and this positioning is important. For example, a routing member in which a feeder line is routed, a wire hanger attached to the routing member and fixing the feeder line to the routing member, and the movable body in a non-contact state with respect to the feeder line And a power receiving device that supplies the mobile body with power obtained by electromagnetic induction by current flowing through the power supply line, and a wire hanger for the wiring member in a direction along the wiring path of the power supply line. You may make it comprise the positioning structure which positions the said electric wire hanger to the said wiring member so that an attachment position can be selected.
According to this configuration, the wire hanger can be positioned on the routing member so that the attachment position of the wire hanger with respect to the routing member in the direction along the routing path of the feeder line can be selected by the positioning structure. A desired position of the electric wire can be fixed to the wiring member by the electric wire hanger, and the assemblability of the non-contact type power feeding device can be improved.

(Embodiment 2)

By accumulating, it is possible to detect how much the table is consuming at the same time. For example, by placing a display unit on the table, the payment amount can be displayed to the customer.

  As described above, according to the rotary sushi apparatus of the present embodiment, since it is a non-contact power feeding method, power can be fed without a sliding part and driven by an induced electromotive force induced in the pickup part 1. By supplying power to the apparatus, the conveying plate is driven, so that no wear powder is generated and the frequency of maintenance can be reduced in a clean environment.

  In the above embodiment, the color of the dish is used as the identifier. However, an identifier for realizing shape identification or a barcode placed on the back of the dish may be used.

  Further, an identifier for realizing weight identification may be used as the identifier, and the type of food may be identified by performing weight detection using a weight sensor that is similarly fed by non-contact power feeding.
