Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a time switch with a weekly setting function used for turning on and off power for machine tools, lighting equipment, etc.

[Background Art] This type of time switch has a time switch that is driven on and off by a time setting setter that is removably attached to a local part of a dial that rotates once a day, and is linked to the dial and rotates once a day. For example, a day signal switch activated at midnight and seven day selection switches are used to select whether to enable or disable the load, and is called skipping disabling.

The conventional configuration of this type of time switch is
As shown in No. 191389, when weekly setting (setting of days to be skipped) is performed, it is done entirely mechanically or by connecting a discrete electronic circuit to the mechanical method. FIG. 12 shows a configuration diagram of a conventional example, which is configured as follows. That is, the clock mechanism section 51 is composed of a dial that rotates once a day, and a time switch 52 that is turned on and off by a timer time setting setter that is detachably attached to the circumference of the dial, and A switch 54 that is turned on for a certain period of time at midnight in conjunction with the rotation to generate a day change pulse from the day change pulse generator 53, and a switch 54 that inputs the day change pulse as a clock, and cyclically each time the clock is input,
A day-of-the-week signal generation circuit 56 consisting of a heptadary counter 55 having seven output terminals corresponding to each day of the week, which shifts the output terminal at which an output is generated, and one end connected to the corresponding output terminal and the other end connected in common. Seven day selection switches 57
L/-58 is turned on by the output signal of the day of the week signal generation circuit 56 inputted via the day of the week selection switch 57.
and a transistor 59 for operating the relay 5.
This is a time switch with a skip-day function in which a load 61 is connected to a power source through a series circuit of a relay contact 60 of 8 and a time switch 52.

By the way, in the time switch of this conventional configuration, the contact point of the time switch 52 that controls the load, the contact point of the relay 58 that is turned on by the output signal of the day of the week signal generation circuit 56,
Since α60 are connected in series, the capacitance of the contact depends on the capacitance of one of the contacts. Therefore, in order to open and close a high-capacity power supply, both the relay 58 and a switch that is turned on and off by a setter (hereinafter referred to as a load switching mechanical switch) must have a high capacity, and in the case of a relay, the current consumption In the case of load opening/closing mechanical switches, due to the increase in capacity, shape with higher capacity, cost increase, etc., in the case of load opening/closing mechanical switches, there is a problem of heat generation in the contact spring, and the need for higher torque of the motor that rotates the dial due to the increase in contact pressure for higher capacity. Therefore, there are major restrictions on cost increase and miniaturization. Furthermore, reliability due to contact deterioration also decreases because it depends on both the relay and the load opening/closing mechanical switch. Furthermore, it is conceivable to take out only the signal from the load opening/closing mechanical switch of the time switch without opening or closing the load, construct the electronic circuit with discrete electronic components, and drive the relay, but this would increase the cost and size.

[Object of the invention] The present invention is provided in view of the above-mentioned α,
The signals from the day change switch, time setting state detection switch, and day contact switch are taken in, and the generation of relay signals is carried out by a processing unit consisting of a microcomputer.The mechanical switch can be used with a low load, and is compact. The purpose of the present invention is to provide a time switch with a weekly setting function, which aims to significantly improve reliability, improve reliability, and reduce costs.

[Disclosure of the Invention 1 (Configuration) The present invention provides a clock IfI having a dial that rotates once a day.
i structure, a time setting state detection switch that is turned on and off by a time setting setter attached to the circumference of the dial, and a time setting state detection switch that is turned on and off for a certain period of time around midnight in conjunction with the dial to set the day of the week. A day of the week change switch that generates a change pulse, a day of the week selection switch for weekly settings that selects seven days of the week, and signals from the time setting state detection switch, day of the week change switch, and day of the week selection switch to drive the load on and off. Equipped with an arithmetic processing section consisting of a microcomputer that generates signal pulses to be applied to the relay, and a power supply circuit section that supplies power to the arithmetic processing section, the arithmetic processing section consisting of a microcomputer can detect the time setting state detection switch and change the day of the week. Signals from the switches and the day selection switch are taken in to generate signal pulses to be applied to the relays that turn on and off the load.In other words, the control signals from each switch are processed by an arithmetic processing section consisting of a microcomputer. In addition, the opening/closing mechanism for opening and closing the load is made possible by using only relays to open and close high-capacity current, and the signals from each switch are input to the arithmetic processing unit, allowing parts to handle small signals. This allows for the use of low operating force.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of a time switch according to the present invention,
A switch section mainly consisting of a power supply circuit section 6, a latch relay RF, a motor M, an arithmetic processing section 5 consisting of a microcomputer, and a mechanical switch mechanism such as a time setting state detection switch, a day of the week change switch, a day of the week selection switch, etc. It consists of 10. Also provided are a power failure detection circuit 7 for detecting a power failure, a reset circuit 8 for initializing the arithmetic processing unit 5 after power is turned on, and the like. Battery 9 is for backup. The schematic configuration of the switch section 10 is as follows. The switch unit 10 generates a day of the week change pulse, detects a time setting state, and detects a week setting state. The day of the week change pulse has a switch that is turned on once every 24 hours, and when this is turned on (for example, turned on at midnight), the day of the week is changed (to the next day).

FIG. 2 shows a top view of a time switch according to the invention,
The time setting state is detected by tilting down or standing up the setting element embedded in the dial 11, and detecting the state with a microswitch via an arm or a lever. This microswitch is! The zero week setting, which constitutes the time setting state detection switch, is set and detected by the sliding day selection switch 4. Each time the day of the week setting button 12 is pressed, the day of the week light emitting diodes LEDs corresponding to the day of the week selection switches 4 at 4 b . . . 4g advance one by one.

The day of the week selection switches 4a...4g are set to [Sun, 1...], respectively.
This corresponds to [Mon-1...r Sat]. The manual on/off switch 13 is in the off position and in the human position.
Regardless of the status of the time setting state detection switch and the normal/continuous changeover switch 14 of the day selection switch 4, when it is off, the output is turned off, when there is a person, the output is turned on, and when it is in the center automatic position, the time is set. The arithmetic processing section 5 determines the states of the setting state detection switch, the day selection switch 4, and the normal/continuous changeover switch 14, and turns off the output. The signal from the day of the week setting button 12 is also taken into the arithmetic processing unit 5, and is also used to determine the output of the day of the week light emitting diode LED, .

The day of the week light emitting diode LED displays the current day of the week.

The signal from the day of the week setting button 12 and the signal from the day selection switch 4 are taken into the arithmetic processing section 5, and the lighting is controlled by the arithmetic processing section 5. In addition, the day of the week light emitting diode L E
When D+... is lit or off, it indicates that the AC power is energized. The output light emitting diode LEDo indicates the output state, and lights up when the output is on, and turns off when the output is off. The lighting and turning off of this output light emitting diode LEDo is also controlled by the arithmetic processing unit 5. Each mechanical day selection switch 4,
Manual on/off switch 13, normal/continuous changeover switch 14
, signals from time setting state detection switches, which are microswitches driven by the rotation of the dial 11, are respectively input to the arithmetic processing section 5 and controlled.

In this way, the arithmetic processing unit 5 controls each switch 4...
・Detects the state of and turns latch relay Ry on and off. The on/off conditions for the latch relay RV are described in the third section below.
According to the 70-chart shown in the figure.

Further, the arithmetic processing section 5 controls the rotation of the motor M that drives the dial 11 that sets and detects the time setting state of the timepiece mechanism section 1, the lever, the arm, and the like.

FIG. 4 shows an exploded perspective view of the time switch. There is a stepping motor (not shown) controlled by an arithmetic processing unit 5 in the watch fi ellipse 1 which is a movement block, and when this stepping motor rotates, the dial 11 is controlled via several gears (wheel train). rotates once a day.

Ninety-six setting elements are attached to the circumference of the dial 11. A lever 15, an arm 16, a switching cam 18, and several gears are arranged between an upper plate 24 and a lower plate 25. A latch relay R31 and a power supply circuit section 6 are mounted on the printed board 21, and an arithmetic processing section 5, light emitting diodes LEDoSLED, etc. are mounted on the printed board 22. Further, the printed board 23 is equipped with a day selection switch 4, a day setting button 12, a manual on/off switch 13, a normal/continuous changeover switch 14, and the like. The day change switch 3 that generates the day change pulse at midnight is made up of two contact pieces 2.
6. Consists of a gear 28 that drives the contact piece 26, etc. Each of these members is made of net inside a lower case 19, and an upper case 20 is placed over the upper surface of the lower case 19. Lower case 1
A terminal block 30 provided with a terminal screw 28 and a terminal fitting 29 is attached to the lower surface of the terminal case 9, and the lower case 19 and the upper case 20 are fixed by a mounting fitting 31. A nameplate 32 is attached to the upper surface of the upper case 20.

FIG. 5 shows a perspective view of the main part of the structure for detecting the time setting state, in which a setter 17 is attached to the circumference of the dial 11.
It is rotatably mounted in the radial direction of 1. A claw piece 17a is integrally formed at the lower part of the setter 17.
By keeping it upright or knocking it down, dial 1
The lever 15, which is in contact with the circumference of the dial 11, rotates with or without a claw piece 17a on the circumference of the dial.

When the lever 15 rotates, the arm 16 moves, and the drive lever 33 in contact with it rotates, driving the push button 2a of the time setting state detection switch 2, which is a microswitch in the clock mechanism section 1, to set the time. Turn the state detection switch 2 on and off.

Next, day of the week selection switch 4 and normal/continuous changeover switch 1
The operations in normal mode and continuous mode in 4 will be explained. The day of the week selection switch 4 is a switch for setting the operation on each day of the week, and the normal/continuous changeover switch 14 is a switch for setting the operation mode, and changes the meaning of the day of the week selection switch 4. First, FIG. 6 shows a time chart showing the daily operation in the normal mode, in which the day selection switch 4 is set to ``auto'' on Sunday, Monday, and Thursday, and to ``off'' on Tuesday and Wednesday. "
On days of the week set to ``Auto'', press the time setting status detection switch (
When the microswitch) 2 changes from off to on, the output is turned on (8:00), and when it changes from on to off, the output is turned off (16:00). On days of the week set to [Off], the output will not turn on even if the time setting state detection switch (micro switch) 2 changes from off to on.
It remains off. When the time setting state detection switch 2 changes from on to off, the output is turned off. In addition, if the time setting state detection switch 2 is on during the day (for example, from 20:00 to 0:00 until 4:00), the time setting state on the day of the week set to "off" will be displayed. The output remains on until the detection switch 2 changes from on to off (4:00).

Next, the continuous mode will be explained. FIG. 7 shows a time chart of daily operation in continuous mode. In FIG. 7, the day of the week selection switch 4 is operated to set Monday, Tuesday, and Thursday to "auto" and Wednesday to "off." On days of the week set to [Auto], even if the time setting state detection switch 2 changes from on to off, the output does not turn off and remains on. When the time setting state detection switch 2 changes from off to on, the output is turned on. On days of the week set to "off", the state does not change even if the time setting state detection switch 2 changes from off to on. When the time setting state detection switch 2 changes from on to off, the output is turned off. Therefore, in continuous mode,
The output is turned on from 8200 on Mondays to 4:00 on Wednesdays.

Next, the overall operation will be schematically explained using chart 70 in FIG. When the power is turned on, the reset circuit 8 initializes the arithmetic processing section 5, and if the test mode is released, it is checked whether or not there is a timer interrupt. If there is a timer interrupt, one pulse is output to the stepping motor of the clock mechanism section 1. Here, if the day of the week change switch 3 is turned on from off, the day of the week light emitting diode LED, . . . is advanced by one. If the day of the week change switch 3 is off, the power outage detection circuit 7 detects a power outage.

If there is a power outage, light emitting diode LED.

..., the output light emitting diode LEDol; is turned off, and the latch relay Ry is turned off. If there is no power outage, data from the manual on/off switch 13, day selection switch 4, and microswitch (the microswitch shown in FIG. 3 is the time setting state detection switch 2) is taken into the arithmetic processing unit 5. . The funeral processing unit 5 repeats this routine if 1) each input data is the same as the previous time. If the data is not the same as the previous time, it is determined whether the state of the manual on/off switch 13 is "on", "automatic", or "off". If the manual on/off switch 13 is "off", the latch relay RY is turned off. Moreover, if it is "on", the latch relay Ry is turned on. If the manual on/off switch 13 is "Auto J", the normal/continuous changeover switch 14
Determine whether the mode is “normal mode” or [continuous mode], and select normal/
If the continuous changeover switch 14 is in the "normal mode", as shown in FIG.
If the current day selection switch 4 is on, the latch relay RV is turned on. When the latch relay R5/ is on, the output light emitting diode LEDo lights up. Also, when the micro switch is turned from on to off, the latch relay RY
is off. If the normal/continuous changeover switch 14 is set to ``1 continuous mode,'' as shown in FIG. 7, the microswitch changes from off to on, and if the current day of the week selection switch 4 is on, the latch relay Ry is turned on. Further, if the microswitch changes from on to off and the current day of the week selection switch 4 is off, the latch relay Ry is turned off. Incidentally, the above-mentioned microswitch refers to the time setting state detection switch 2 as described above.

In this way, the signals from each switch are processed by the arithmetic processing section 5 made up of a microcomputer to control on/off of the latch relay RV, thereby reducing the number of mechanical parts and discrete parts that make up the electronic circuit. The parts that make up each switch can also be small and require low operating force for signal control.
It is possible to reduce the size and cost of the product. In addition, the latch relay Ry directly opens and closes the load.
Since the number of components that pass high-capacity current is reduced, heat generation and insulation measures can be reduced. In addition, since a microcomputer is used in the arithmetic processing unit 5, other functions such as an interrupt function (FPI function that can be forcibly turned off even if the output is on only when the signal is input), It can provide Noh Takatsuki's time switch, such as a daytime function.

Next, day-to-day control will be explained. In FIGS. 6 and 7, the time setting on the dial 11 is from 20:00 to
At 4:00, it is in the state of day migration (setting state of on). On the contrary, when the normal/continuous switching switch 14 is in the on setting state from 4:00 to 20:00, the time chart when the normal/continuous switching switch 14 is in the normal mode is shown in Fig. 8, and the time chart when it is in the continuous mode is shown in Fig. 8. They are shown in Figure 9. In the case of Figure 8, Monday is set to "Auto" and Tuesday is set to "Off", and in the case of Figure 9, Monday and Tuesday are set to "Auto" consecutively.
This is what we do. In this way, by different time settings on the dial 11, different output operation patterns can be provided.

Incidentally, when performing day-to-day control, the time at which the day-of-the-week changing pulse for changing the day of the week is generated is important. FIG. 10 is a time chart showing the day-to-day operation in continuous mode when the turn-on time is set to 23:45 and the turn-off time is set to 0:00. Since the above-mentioned 16 - time setting state detection switch (micro switch) 2 and day change switch 3 consisting of contact piece 27, teeth 28, etc. are mechanical switches, the times at which signals are generated are somewhat different (.Time setting state detection Considering the time based on the time when switch 2 was activated, when the day of the week change pulse occurs, the day of the week is forwarded, which becomes %0:00, but this pulse is from 23:45 to 0:00. If it does not occur at 1) 23:45, the predetermined daily pattern cannot be obtained.
An output pulse is obtained at ~0:00, and while this pulse is still being generated, a day-of-the-week change pulse is generated at time t.

Therefore, in this case, the output is on, and on Thursdays when it is set to "auto", the output is on. 23 on Thursday generated by time setting state detection switch 2
The day of the week change pulse occurs at time t2 between the pulses of :00 and 0:00, and the day of the week change pulse is set to "off" at 0:00 on Friday.
The output is turned off.

FIG. 11 shows that the day change pulse from the day change switch 3 is generated from the time setting state detection switch 2 at 23:45.
12 is a time chart showing daily operation in continuous mode when no occurrence occurs between 0:00 and 0:00. Time setting state detection switch 2 does not occur between 23=45 and 0:00,
The operation when this occurs after 0:00 is shown. The signal from the time setting state detection switch 2 is turned on at 23:45, and the
:00, an off signal is generated, but after this, a day of the week change pulse is generated from the day of the week change switch 3 at time t3, and the day of the week is forwarded, so on Wednesday, when the day of the week selection switch 4 is "off", the IJ setting state detection switch is turned off. It does not accept the ON signal of 2 and does not operate during the day.

In addition, 23 by the time setting state detection switch 2 on Thursday:
A signal is output between 45 and 0:00, and a day of the week change pulse is generated after this signal.

In other words, the time when the last setter of the week turns on or off (for example, in a dial 11 equipped with a setter with a minimum setting time interval of 96, if (24 x 60 minutes) / 96 = 15 minutes, then 23: The day of the week change pulse is generated from the day of the week change switch 3 at the opening of 45.0:00, so that day-to-day operation in continuous mode can be obtained in a predetermined pattern. In this way, day of the week change pulses from the day of the week change switch 3, signals from the time setting state detection switch 2, etc. are taken in, and the arithmetic processing unit 5, which is made up of microswitches, generates relay signals, motor drive pulses, etc., and the day of the week is set. As mentioned above, by setting the mode of the day selection switch 4 and the normal/continuous changeover switch 14 to OFF, normal, and continuous, various output operations can be performed. It is possible to obtain a pattern. In addition, since the time setting on the dial 11 using the setter 17 and the changeover switches 4 and 14 for other modes are independent, the settings are easy. Even if it is turned on or off, it is possible to perform a predetermined daily operation.

[Effects of the Invention] As described above, the present invention includes a timepiece mechanism having a dial that rotates once a day, and a time setting device that is turned on and off by a time setting setter attached to the circumference of the dial. A state detection switch, a day change switch that is linked to a dial and turns on for a certain period of time around midnight to generate a day change pulse, a day selection switch for weekly settings that selects seven days of the week, and the time setting. An arithmetic processing section consisting of a microcomputer that takes in signals from the state detection switch, day of the week change switch, and day selection switch and generates signal pulses to be applied to relays that drive loads on and off; and a power supply circuit section that supplies power to the arithmetic processing section. Therefore, the arithmetic processing section consisting of a microcomputer takes in signals from the time setting state detection switch, day of the week change switch, and day of the week selection switch and generates signal pulses to be applied to relays that drive the load on and off. In other words, the control signals from each switch are processed by an arithmetic processing unit consisting of a microcomputer, and the only switching mechanism for switching the load is a relay, which can switch and close high-capacity current. By doing this, it is possible to reduce the number of mechanical parts and discrete parts that make up the electronic circuit, and the parts that make up each switch can also be made smaller and with less operating force for signal control. This makes it possible to reduce the size and cost of the product. In addition, relays are the only ones that directly open and close the load, reducing the number of components that pass high-capacity current.
This can reduce heat generation, insulation measures, etc. In addition, since a microcomputer is used in the arithmetic processing section, other functions, such as an interrupt function (a function that can force the output to turn off even if the output is on only when the signal is input), This has the effect of providing a highly functional time switch such as functions.
