It has a coil 31.

That is, a magnetic field is generated by the coil 31, and a voltage is generated in the component shelf 4 by this change. Due to the generation of this voltage, a current flows through the component shelf 4 without making contact with the coil 31, and the power of the coil 31 is transmitted to the component shelf 4.

The component shelf 4 includes a conductive frame 41 (frame body) shown by a thick line in the figure and an insulating frame 42 shown by a chain line in the figure.
And a plurality of component storage portions 43 formed by dividing the component shelf 4 by the conductive frame 41 and the insulating frame 42.

Each component storage unit 43 is provided with a component instruction control unit 5, and the component instruction control unit 5 issues a component instruction. The component instruction control unit 5 is provided on the conductive frame 41,
Electric power is supplied to the conductor of the conductive frame 41 without being in contact with the conductor.

The configuration of the component instruction control unit 5 is as shown in FIG.

FIG. 2 is a block diagram showing the configuration of the component instruction control unit 5, and FIG. 3 is a graph showing the frequency of the current flowing through the component instruction control unit 5.

As shown in FIG. 2, the parts instruction control unit 5 is
The coil 51, the filter 52, the limiter 53, the lighting circuit unit 54, the lighting determination unit 6, and the transformer coupling circuit 7 are included.

The coil 51 is the conductive frame 4 of the parts shelf 4.
Is arranged in the vicinity of the conductor 41a attached to 1,
It is connected to the transformer coupling circuit 7 and the filter 52. Since a magnetic field is generated by the current flowing through the conductor 41a, a voltage is generated in the coil 51 due to the change in this magnetic field. Due to this voltage, a current flows through the transformer coupling circuit 7 and the filter 52.

The filter 52 is provided to eliminate noise.
It blocks passage of a frequency region that does not relate to a frequency pattern, which will be described later, of the flowing current. Further, the limiter 53 limits the amplitude of the signal waveform due to the current. The current that has passed through the limiter 53 is input to the lighting determination unit 6.

The lighting determination section 6 is composed of a serial reception section 61 (recognition means), an identification pattern storage section 62 (storage means), and a pattern comparison section 63 (comparison means). The serial reception unit 61 and the identification pattern storage unit 62 are each connected to the pattern comparison unit 63. Further, the pattern comparison unit 63 is connected to the lighting circuit unit 54.

The serial receiving unit 61 recognizes a time-series arrangement pattern of frequencies of received currents, that is, a combination pattern of frequencies, and outputs the combination pattern to the pattern comparison unit 63. Here, the combination pattern of frequencies means, for example, as shown in FIG.
It is a pattern in which "0" is represented by 00 kHz and "1" is represented by 530 kHz, and these different frequencies are continuously combined.

The identification pattern storage unit 62 stores in advance a combination pattern of predetermined frequencies as an identification pattern for identifying that the component instruction control unit 5 controls the instruction of the component.

The pattern comparing section 63 is a serial receiving section 6
The combination pattern recognized in 1 is compared with the identification pattern stored in the identification pattern storage unit 62, and if the same, the control signal is transmitted to the lighting circuit unit 54.

The lighting circuit section 54 controls the switch 71 of the transformer coupling circuit 7 to be ON based on the control signal transmitted by the pattern comparison section 63.

The transformer coupling circuit 7 includes a component designating lamp 70 (component designating means) and a switch 71. When the switch 71 is turned on by the lighting circuit unit 54, the component instruction lamp 70 is turned on. Parts instruction lamp 70

It is possible to instruct the operator to take out the parts from 3.

Next, the operation of each device for instructing parts will be described.

First, the operation of the host controller 2 will be described.

FIG. 4 is a flow chart showing the operation of the host controller 2.

As shown in FIG. 4, the host controller 2 first controls the power supply device 3 so as to supply a current to the parts shelf 4 in a combination pattern of frequencies for extinguishing (hereinafter referred to as extinguishing pattern) (step). S1). Here, the extinguishing pattern is, for example, 500 kHz so that the frequency combination pattern becomes “00000000”.
It is a pattern in which the frequency of is continuously output eight times. Unless otherwise specified, the current is always supplied in the light-off pattern. Since each component instruction lamp 70 is extinguished, the extinguishing pattern is a pattern that is not stored in the identification pattern storage unit 62 of any component instruction control unit 5.

Then, the host controller 2 determines whether or not to check the lighting of the component instruction lamp 70 of each component instruction control section 5 (step S2). When checking the lighting of the parts instruction lamp 70 (step S2: Y
ES) is a power supply device 3 that supplies a current to the component shelf 4 in a combination pattern of frequencies for checking lamp lighting.
To control.

When the lighting of the component instruction lamp 70 is not checked (step S2: NO), the host controller 2
Determines whether or not to instruct a component to be taken out in consideration of the work progress of the worker (step S4).

When no parts are designated (step S4: N
O), the power supply device 3 is directly supplied with a current at 500 kHz. When instructing parts (step S4: YE
S), so that the current is supplied in a combination pattern having the same frequency as the identification pattern stored in the identification pattern storage unit 62 of the component instruction control unit 5 provided in the component storage unit 43 in which the component to be instructed is stored. The power supply device 3 is controlled (step S5).

It is necessary to turn on the component instruction lamp 70 for a predetermined time until the operator takes out the component from the component storage section 43. Therefore, it is judged whether or not the predetermined time has elapsed (step S6). ), If the predetermined time has not elapsed (step S6: NO), the process returns to S5, and if the predetermined time has elapsed (step S6: Y).
In ES), the process of S5 is ended and the process from the start is repeated.

As described above, the power supply device 3 is controlled by the host controller 2 and the electric power is transmitted to the parts shelf 4. The electric power transmitted to the parts shelf 4 is transferred to the conductive frame 4
It is transmitted to the component instruction control unit 5 in a non-contact manner by the coil 51 through the conductor 41a included in 1.

Next, the operation of the parts instruction controller 5 will be described.

FIG. 5 is a flowchart showing the operation of the component instruction control unit 5.

First, the component instruction control section 5 recognizes the combination pattern of current frequencies in the serial receiving section 61 (step S11). Then, in the pattern comparison unit 63,
The recognized combination pattern is stored in the identification pattern storage unit 6
2 is compared (step S12) with the own identification pattern, and if the same as the own identification pattern (step S12: YES), the parts instruction lamp 70 is turned on to instruct the operator about the parts. Therefore, the lighting circuit unit 54
A control signal to turn on the component instruction lamp 70 (step S13).

If it is different from its own identification pattern (step S12: NO), it is judged whether the recognized combination pattern of frequencies is a check pattern (step S14), and if it is a check pattern (step S1).
4: YES), in order to check the lighting of the component instruction lamp 70, a control signal is transmitted to the lighting circuit unit 54 to light the component instruction lamp 70 (step S14). If the pattern is not a check pattern (step S14: NO),
The operation ends as it is.

In the component instruction system 1 of the present invention described above, the conductive frame 41 constitutes a plurality of component storage portions 43, so that the conductive frame 41 itself can transmit a current, and this current is generated. A voltage is induced in the coil 51 of the component instruction control unit 5 due to the change in the magnetic field. Therefore, the component instruction lamp 70 and the component instruction control unit 5
Can obtain electric power without directly contacting the conductive frame 41. As a result, no wiring or the like is required to supply power to the component instruction lamp 70 and the component instruction control unit 5, and the wiring is erroneously cut even if components are frequently taken in and out of the component storage unit 43. , The equipment never stops.

Further, by passing a current through the conductive frame 41 itself, the component instruction control section 5 and the component instruction lamp 7
Since 0 can be supplied with electric power, it is not necessary to provide any means for transmitting electric power in addition to the conductive frame 41. Therefore, the structure of the equipment can be simplified and the equipment can be downsized.

Furthermore, the component instruction control unit 5 controls the lighting of the component instruction lamp 70 based on the electric power of the power supply device 3 controlled by the host controller 2, that is, based on the frequency of the supplied current. Which component indicating lamp 70 is turned on to indicate a component can be achieved by adjusting the frequency. Therefore, it is not necessary to separately prepare a signal line and transmit a signal for instructing which component instructing lamp 70 to instruct a component, and as a result, it is not necessary to connect the signal line to the component shelf 4. Since no signal line is required, disconnection of the signal line does not occur, and it is possible to prevent equipment stoppage due to the disconnection.

As described above, since wiring and signal lines are not required, when rearranging or increasing the number of component storage parts 43, the number of man-hours for arranging wiring and signal lines is not required, and the component instruction system 1, particularly the components. The configuration of the shelf 4 can be easily changed.

Furthermore, the parts instruction control section 5 respectively
The combination pattern of predetermined frequencies is stored in advance in the identification pattern storage unit 62 as an identification pattern, and this identification pattern is compared with the combination pattern of the frequencies of the currents recognized by the serial reception unit (recognition means) to find the same pattern. In this case, the parts instruction lamp 70 is turned on. Therefore, if the identification patterns stored in the respective component instruction control units 5 are made different, the power supply device 3
By controlling the combination pattern of the frequencies of the currents supplied from, it is possible to turn on the component indicating lamp for which it is desired to indicate the component.

The power supply device 3 uses the magnetic field of the coil 31 to
Since electric power can be supplied without contacting the parts shelf 4, no wiring is required between the power supply device 3 and the parts shelf 4,
As a result, even if a component is frequently taken in and out of the component storage unit 43, the wiring is not accidentally cut and the facility does not stop.

(Second Embodiment) Next, a second embodiment of the parts instruction system 1 of the first embodiment will be described in which the configuration in the parts instruction control unit 5 is partially changed. .

FIG. 6 is a diagram showing the configuration of the parts instruction control unit 5 in the second embodiment. In the second embodiment, the configuration of the lighting determination unit 6'of the component instruction control unit 5 is different from that of the first embodiment. Therefore, other configurations are similar to those of the first embodiment, and therefore, the same reference numerals are given and the description thereof is omitted.

The lighting determination unit 6'includes the identification frequency storage unit 65.
And a frequency comparison unit 66. The frequency storage section (storage means) 65 stores in advance an identification frequency for identifying that the component instruction lamp 70 is turned on. The frequency comparison unit (recognition unit, comparison unit) 66 recognizes the frequency of the current transmitted by the conductor 41 a and compares it with the identification frequency stored in the identification frequency storage unit 65. Based on the result of this comparison, if the frequencies are the same,
The lighting circuit unit 54 is controlled to turn on the component instruction lamp 70.

Next, the operation of each device will be described. In the second embodiment, which component storage lamp 43 is to be turned on is determined not by the frequency combination pattern but by the frequency itself. Therefore, the operation of the host controller 2 to control the frequency of the power supply device 3 is also different, so the operation of the host controller 2 will be described first.

FIG. 7 is a flow chart showing the operation of the host controller 2 in the second embodiment.

First, the host controller 2 is connected to the power supply 3
To supply a current at the extinction frequency to extinguish each component instruction lamp 70 for the time being on the component shelf 4 (step S2).
1). Here, the turn-off frequency is a frequency that is not stored in the identification frequency storage unit 65 of any component instruction control unit 5, and does not become the identification frequency. Since the frequency does not become the identification frequency, when the current is supplied at the extinction frequency, each component instruction lamp 70 is extinguished.

Next, it is determined whether or not the lamp lighting check is performed (step S22). When the lamp lighting check is performed (step S22: YES), the power supply device 3 is caused to supply the current at the check frequency (step S2).
3). Here, the check frequency is, for example, 25
It is 0 kHz. When a current is applied at this check frequency, all of the component indicating lamps 70 are turned on.

When the lamp lighting check is not performed (step S22: NO), the host controller 2 determines whether or not to instruct a component to be taken out in consideration of the work progress of the worker and the like (step S4).

When no parts are designated (step S24:
NO), the power supply device 3 is directly supplied with current at 250 kHz. When instructing parts (step S24: YE
S), the power supply device 3 so that the current is supplied at the same frequency as the identification frequency stored in the identification frequency storage unit 65 of the component instruction control unit 5 provided in the component storage unit 43 in which the component to be instructed is stored. Is controlled (step S25).

It is necessary to turn on the component instruction lamp 70 for a predetermined time until the operator takes out the component from the component storage section 43. Therefore, it is judged whether or not the predetermined time has elapsed (step S26). ), If the predetermined time has not elapsed (step S26: NO), the process returns to S25, and if the predetermined time has elapsed (step S26).
26: YES), the process of S25 is ended, and the process from the start is repeated.

As described above, the power supply device 3 is controlled by the host controller 2 and the electric power is transmitted to the parts shelf 4. The electric power transmitted to the parts shelf 4 is transferred to the conductive frame 4
It is transmitted to the component instruction control unit 5 by the coil 51 through the 41 a of 1.

The operation of the parts instruction controller 5 will be described.

FIG. 8 is a flow chart showing the operation of the parts instruction control unit 5 in the second embodiment.

First, the component instruction control unit 5 includes the frequency comparison unit 6
The frequency of the current is recognized in step 6 (step S31), and the recognized combination pattern is compared with the identification frequency of its own stored in the identification frequency storage unit 65 (step S3).
2) If it is the same as its own identification frequency (step S3)
2: YES) sends a control signal to the lighting circuit unit 54 in order to instruct the operator of the component, and the component instruction lamp 7
0 is turned on (step S33).

If it is different from the identification frequency of its own (step S32: NO), it is judged whether the recognized frequency is a check frequency (step S34). If it is the check frequency (step S34: YES), it is for component instruction. In order to check the lighting of the lamp 70, a control signal is transmitted to the lighting circuit unit 54 to turn on the parts instruction lamp 70 even if it is different from the identification frequency (step S34). If the frequency is not the checking frequency (step S34: NO), the operation is ended without turning on the parts instruction lamp 70.

As described above, in the second embodiment, a predetermined identification frequency is stored in advance in the identification frequency storage unit 65 of the lighting determination unit 6, and this identification frequency is used as the frequency comparison unit 6.
6, the lighting circuit section 54 is controlled so that the component indicating lamp 70 is turned on when the frequency is the same as the frequency recognized by the reference numeral 6. Therefore, if the identification frequencies stored in the respective lighting determination units 6 are made different from each other, only the desired component indicating lamp 70 can be turned on by controlling the frequency of the current supplied from the power supply device 3. Therefore, it is possible to accurately instruct the operator about the parts.

In the first and second embodiments, the component instruction control unit 5 includes the lighting determination unit 6 and the lighting determination unit 6 '.
Although they are separately provided, they can be used together. In this case, for example, the lighting determination unit 6
The identification patterns stored in are 500 kHz and 530 kHz.
z is a pattern in which frequencies are combined, and the identification frequency stored in the lighting determination unit 6 ′ is 250 to 450 k.
It is necessary to prevent the frequency bands used by the lighting determination unit 6 and the lighting determination unit 6 ′ from overlapping by setting the frequency band to be in the range of Hz.

A bandpass filter may be used instead of the lighting determination units 6 and 6 '. The bandpass filter can pass only a predetermined frequency band.
Therefore, the lighting circuit 5 passes through the band pass filter.
Only when a current flows through the lamp 4, the component instruction lamp 70 can be turned on. If the component instruction control unit 5 includes a bandpass filter that passes different frequencies, the desired component instruction lamp 70 can be turned on by controlling the frequency of the current supplied from the power supply device 3. .
