Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a timer capable of outputting a plurality of timer outputs, and more specifically, from the start of a timer operation to the time-out of outputting a timer output. And a timer which can individually set the timer time according to each of the plurality of timer outputs.

(Prior art and its problems) As an example of a soft drink vending machine using two timers of this type as timer setting knobs, a description will be given of the inconvenience of using the timer. Point out.

That is, in a soft drink vending machine, zm in total amount
When the ingredients A and B of the soft drink are supplied and mixed at a constant mixing ratio x: y for one small cup of l, the timer A is set to 5 seconds by operating one of the setting knobs to supply the ingredient A. And supply the material B to the small cup by the same setting knob and set the operation timer time of the other setting knob to 7 seconds, and supply the material B to the small cup by the same amount as the yml via the supply device. Some timers use the timer to obtain a full refreshment.

When using such a timer, the total amount is 120% of zml
To supply the ingredients A and B to the large cup to obtain a soft drink having the same taste as above, one of the setting knobs is operated to set the timer time to 120% of 5 seconds, that is, the timer time of 6 seconds. It is necessary to operate the other setting knob to set the timer to 120% of 7 seconds, that is, 8.4 seconds.

Therefore, in such a timer, when the mixing ratio of each of the materials A and B is held and the total amount is changed to 120% of zml as in the above example, the calculation of the time timer is performed. It is necessary to change the timer time by operating each setting knob corresponding to the calculation.

However, such a change in the setting of the timer time requires calculation of the timer time for each setting knob, and furthermore, there is a problem that it is very difficult to operate each of the setting knobs according to the calculation. Of course, as described above, if there are only two types of small cups and large cups, there is no problem if the automatic setting can be automatically performed inside the vending machine from the beginning, but if the total amount is appropriately adjusted, such a case is not possible. No automatic set is possible, and that problem cannot be avoided.

Therefore, in the present invention, when a plurality of timer times are individually set, when each timer time is individually extended or shortened while the ratio (percentage) of each timer time is kept constant, the data of the percentage is used. It is an object of the present invention to eliminate the need to individually set the timer time by simply inputting the, and to eliminate the troublesome calculation of the timer time and the complicated operation of the setting knob as described above.

(Means for Solving the Problems) In order to achieve such an object, in the timer of the present invention, a timer time individual setting means, a timer time extension / reduction means, a count pulse generation means, a count means, The timer time individual setting means is independent without considering the operation state of the timer time extension / reduction means in a state where the timer time extension / reduction means is not externally extending or shortening the timer time. In addition, it is possible to individually set a plurality of timer times, and to output a plurality of timer signals corresponding to each of the timer times, and the timer time extending / shortening means sets the plurality of timer times at the same percentage. External operation for extension or shortening is possible, and an operation signal corresponding to the external operation amount is output. The pulse generating means generates and outputs a count pulse, and controls the generation cycle of the count pulse to a cycle corresponding to the operation signal to output the count pulse. The timer signal and the count pulse are input, and the count-up value is set in accordance with each of the plurality of input timer signals, and the timer is incremented every time the count value of the count pulse reaches the count-up value. It is characterized by outputting an output.

(Operation) When a plurality of timer times are individually set by the individual timer time setting means, a plurality of timer signals corresponding to the respective timer times are output from the individual timer time setting means. And when extending or shortening the individually set timer time by the same percentage,
The timer time extension / reduction means is externally operated in accordance with the extension / reduction timer time. As a result, an operation signal corresponding to the external operation amount is output from the timer time extension / reduction means.

The count pulse generation means receives the operation signal and controls the generation cycle of the count pulse in accordance with the percentage of the operation signal as data, and outputs the count pulse.

The counting means performs a counting operation with the previous generation cycle of the count pulse, and counts up when the count value reaches a count-up value set by each of the plurality of timer signals before extension or shortening. While each outputs the timer output,
When the count pulse generation period is extended or shortened from the count pulse generation means, the count operation is performed in accordance with the extension or shortening, and when the count value reaches the count-up value, the timer counts up and outputs a timer output. Is output.

Therefore, when extending or shortening each of the plurality of timer times by the same percentage, the extension or shortening can be performed only by external operation of the timer time extending / shortening means.

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

FIG. 1 is a schematic configuration diagram of a front panel of a timer according to an embodiment of the present invention. The structure of the front panel 2 shown in FIG. Reference numerals 4 and 6 denote first and second timer time setting knobs included in the timer time individual setting means, respectively, which are provided outside the front panel 2 from the independent dual variable resistor main body provided in the front panel 2. It is mounted on each protruding double structure movable terminal. The first timer time setting knob 4 has a setting hand 4a, and the rotation of the knob 4 moves the setting hand 4a along the first timer time setting scale 4b. A timer signal corresponding to the position on the scale 4b is output from the variable resistor main body. The second timer time setting knob 6 has a setting hand 6a. The rotating operation of the knob 6 moves the setting hand 6a along the second timer time setting scale 6b, and the scale 6b of the setting hand 6a. A timer signal corresponding to the upper position is output from the variable resistor main body.

Reference numeral 8 denotes a percentage setting knob included in the timer time extension / reduction means, which is mounted on a movable terminal protruding out of the front panel 2 from a variable resistor main body provided in the front panel 2. The percentage setting knob 8 has a setting hand 8a.
The setting hand 8a is moved in the + or-direction by the rotation operation of, and a percentage signal corresponding to the external operation amount of the setting hand 8a in the + or-direction is output from the variable resistor main body. Here, when the first and second timer times are set by the respective timer time setting knobs 4 and 6, the percentage signal is used to extend or shorten the respective timer times together by, for example, x percent. When the setting knob 8 is externally operated in the + or-direction, it is a signal corresponding to the external operation amount.

Reference numeral 10 denotes a percentage setting display section for displaying the external operation amount of the percentage setting knob 8 by light emission. As an example, 11 display sections 10a, 10b, and 10b corresponding to the percentage from 20% to 22% every 20%. , And each of the display units 10a, 10b,... Is driven to emit light by driving means (not shown) in accordance with the external operation amount of the percentage setting knob 8. Reference numeral 12 denotes a timer output display unit which emits light when the timer is in the output state and displays the output state. The display unit 12a corresponds to the first timer time setting knob 4, and the second timer time setting knob 6 And a display unit 12b corresponding to.

As shown in FIG. 2, the timer having the front panel structure has a count pulse generating circuit 14 to which a percentage signal from a percentage setting knob 8 is applied.
Is provided. The count pulse generation circuit 14 is constituted by, for example, a CR oscillation circuit, and the R portion thereof partially includes a variable resistor of a percentage setting knob 8, and the resistance adjustment of the variable resistor is used as a percentage signal to oscillate the oscillation frequency. Is variable so that the cycle of the count pulse, which is the oscillation pulse, can be adjusted. The timer also includes first and second counters 16 and 18 that operate in response to timer signals from the respective timer time setting knobs 4 and 6 and the count pulse from the count pulse generation circuit 14.

Each of the counters 16 and 18 is set to a count-up value in accordance with a timer signal from each of the timer time setting knobs 4 and 6, and each time the count value of the count pulse becomes the count-up value. The timer output is output to the For example, each timer time setting knob
Rotate 4, 6 to set the setting hands 4a, 6a to scales 4b, 6b
Each counter is moved along the top and the electric signal corresponding to the resistance value adjustment of the variable resistor is
When input to the counters 16 and 18, the counters 16 and 18 are set to a count-up value corresponding to the timer signal.

The operation will be described with reference to FIGS. 3 and 4. First, the first timer setting knob 4 is rotated to set its setting hand 4a to T1 of the scale 4b = 5 seconds, while the second timer is set. Rotate the time setting knob 6 to set the setting hand 6a to the scale 6b
T2 = 7 seconds. At this time, when the percentage setting knob 8 is set to a neutral position which is neither + nor-as shown in FIG. 1, that is, an operation position of 100%, the first timer time setting knob 4 to the first counter 16 display 5 seconds. The second timer signal corresponding to the timer time of 7 seconds is supplied to the second timer time setting knob 6 to the second counter 18 respectively.
Thus, the first counter 16 has a count-up value set to, for example, 50, and the second counter 18 has a count-up value set to, for example, 70. .. Of the display units 10a, 10b,... Of the percentage setting display unit 10 are driven to emit light, and the count pulse is displayed. The generation circuit 14 generates and outputs a count pulse having a cycle of t1 = 0.1 second as shown in FIGS. 4 (a) and 4 (b). FIG. 4A shows the count pulses supplied from the count pulse generation circuit 14 to the first counter 16, and FIG. 4B shows the count pulses supplied from the count pulse generation circuit 14 to the second counter 18, respectively. Therefore, the first counter 14 counts up when the number of count pulses reaches 50, that is, after T1 = 5 seconds, and outputs the first timer output. When the number of count pulses reaches 70, that is, after T2 = 7 seconds, the second counter 18 counts up and outputs the second timer output.

Next, extend each timer time by 120% of the same,
In other words, if you want to change it from 5 seconds to 6 seconds for the first timer time and from 7 seconds to 8.4 seconds for the second timer time, set the percentage setting knob 8 to 120% Operate externally by the amount corresponding to. At this time, the setting hands 4a and 6a of the timer time setting knobs 4 and 6 are on the scale of 5 seconds and 7 seconds as shown in FIG. At this time, by the above setting of the percentage setting knob 8, in the percentage setting display section 10, among the respective display sections 10a, 10b,..., The display section shown in black in FIG. When the timer operation is started in this state, the count pulse generating circuit 14 sets the percentage setting knob 8
In response to the input of the percentage signal, the generation cycle of the count pulse is set to t2 = 1.2 t1 = 0.12 seconds as shown in FIGS. 4 (a) 'and (b)'. Accordingly, the count pulse shown in FIG. 4 (a) '(b)' is given from the count pulse generating circuit 14 to each of the counters 4 and 6 at a period of 0.12 seconds. Since the count-up value is 50, when the count pulse generation cycle becomes 0.12 seconds, the count-up is from T1 = 5 seconds to T1 '= 1.2 T1 = 6 seconds, and the second counter 6 counts the count-up value. 70, so when the count pulse generation cycle reaches 0.12 seconds, it is T2 =
From 7 seconds, T2 '= 1.2 T2 = 8.4 seconds.

As a result, after first setting the timer time setting knobs 4 and 6 to 5 seconds and 7 seconds, respectively, without operating the knobs 4 and 6, only operating the percentage setting knob 8, the timer 5 seconds: 7 seconds = Percentage of time =
6 seconds: 8.4 seconds. In a vending machine for soft drinks, when changing only the total amount of the material A and the material B while maintaining the mixing ratio of 5: 7, the percentage setting knob 8 You only need to operate.

(Effect of the Invention) As is clear from the above description, according to the present invention, when a plurality of timer times are individually set,
When changing the setting of each timer time with the same percentage of extension or shortening of each timer time, it is possible to change the setting of the timer time only by inputting the data of the percentage. The troublesome calculation of the timer time and the troublesome operation of the setting knob become unnecessary.

That is, specifically, in a soft drink vending machine, when mixing the ingredients A and B in a cup at a certain mixing ratio, when changing only the total amount without changing the mixing ratio, This is very convenient because only the percentage setting knob, which is means for extending or shortening the timer time, can be operated.
