Description

[Detailed Description of the Invention] [Industrial Fields of Application] The present invention is capable of programmatically setting an arbitrary pattern for controlling a load on and off, and repeatedly executing the arbitrary pattern at intervals of a set period. This relates to a rotary timer that can be

[Prior Art] As shown in Fig. 4, a rotary timer (or sometimes called a cam timer) is used to turn on and off multiple loads within an arbitrarily settable period (period T in the figure). It is possible to set an arbitrary pattern in a program, and the arbitrary pattern set in the program can be repeatedly executed at intervals of the set period. In this rotary timer, the load program is set as follows. First, the period T is set. In the case of FIG. 4, the period T is 100 seconds. Then, the on and off times from output 1 to output N are set as shown in the following table, for example.

Table 1 In other words, in the case of Figure 4, during a period of 100 seconds, the load corresponding to output 1 is repeatedly turned on and off at 20 second intervals, and output 2 is turned on after 20 seconds within one cycle and turned off after 8 Q seconds. The output N repeats on and off at intervals of 10 seconds. Then, an arbitrary pattern within the period T set as described above is repeated at a period T=100 seconds.

[Problems to be Solved by the Invention] However, with the setting method described above, disconnection occurs when the load is operated in the same pattern as shown in FIG. 4 and only the cycle is desired to be slightly longer. In other words, the time settings for each output remain the same, and the period T is changed from 100 seconds to 1
If the length is increased to 10 se, the load operation pattern will operate in a different pattern from that shown in Fig. 4, as shown in Fig. 5. Therefore, in the conventional rotary timer,
In order to make the load operation pattern the same by changing only the period T, it was also necessary to reset the ON and OFF settings for each output as shown in the following table.

Table 2 The present invention has been made in view of the above points, and its purpose is to change the operation pattern of each load when only the cycle is changed and the operation pattern of the loads is the same. The purpose of the present invention is to provide a rotary timer without any problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a cycle setting means for setting the cycle at a time and an angle corresponding to the time, and a cycle setting means for setting the cycle at an angle corresponding to the angle of the cycle. The apparatus includes an angle setting means for setting the angle, and an arithmetic control means for converting the angle data set by the angle setting means into time data based on a cycle and controlling the operation pattern of the load according to the converted time data.

[Operation] As described above, the present invention sets the motion pattern in advance with data corresponding to the angle of the cycle, so that when only the cycle is changed, the motion pattern is automatically changed according to the cycle. This eliminates the need to change the operation pattern of each load.

[Example] An embodiment of the present invention is shown in FIGS. 1 to 3.

In the rotary timer of this embodiment, the setting of the load operation pattern, which was conventionally input by time, is now input by angle to the cycle.As shown in Figure 1, the repetition cycle is set. A cycle setting section 1 and an angle setting section 2 for setting the load operation pattern in terms of angle are provided, and an arithmetic control section 3 consisting of a built-in microcomputer controls the operation of the load according to the settings of each of these setting sections 1 and 2. It is recommended that you do this. Here, the period setting section 1 inputs the period T as a time and an appropriate angle according to the time. For example, in the case of Fig. 4, the period is set to 100
sec is set, and 360° is set as the angle corresponding to 100 sec. This cycle setting section 1.
The setting time and angle are stored in a setting storage section 4 consisting of a RAM. Angle/time conversion unit 31 of the calculation control unit 3
Then, the angle data inputted from the angle setting section 2 is converted into time according to the set time and angle inputted from the period setting section 1. The above angle data is converted into time data using the following calculation formula.

(Shunsho Cheetah) -" 3 C color Σ - - If 18° is set as the data, the time data will be 5 seconds. The data converted into time data in this way is stored in the setting storage section 4, and based on the stored data in the setting storage section 4, the control section 32 of the arithmetic control section 3 performs a load control based on the clock from the reference oscillator 6. Outputs a control signal to control on/off. Note that the operation of the control section 32 can be controlled by the input section 5.

That is, the input unit 5 can start, end, or reset the timer operation. Furthermore, the control unit 32
Then, display control of the display unit 7 is also performed, and the operating status of the load, input operation status, etc. are displayed.

In this embodiment, when changing the cycle, it is performed as shown in the flowchart shown in FIG. In other words, when you input cycle change data, it is determined whether the change is in the time corresponding to the cycle, and if it is, the previous setting cycle time and the new setting cycle are changed. If they do not match, the newly set time is stored in the setting storage section. Then, based on the time changed at this time, the angle data set by the angle setting section 2 is newly converted into new time data based on the above-mentioned time. On the other hand, if the cycle time is the same as the previous time and only the angle is changed, it is determined that the angle does not match the previous angle, and the angle setting unit 2 sets the cycle accordingly. Convert the angle data into new time data. When changing both the time and angle of the cycle, the above-described method is repeated to convert the angle data into time data.

The angle data is input from the angle setting section 2 as shown in the flowchart of FIG. First, in this case, first determine whether the period time and angle are registered.
When this setting registration has been performed, angle data can be input. If it is possible to input angle data, first input the program number and then input the output number. Then, specify the on/off operation of the load,
Enter angle data. After that, the arithmetic control unit 3 automatically converts the angle data into time data based on the time and angle of the cycle that are set and registered in advance, and converts the angle data into time data based on the output number, ON/OFF designated angle, and the angle. The converted time data is stored in the setting storage section 4. Thereafter, the control section 32 automatically controls the operation of the load in accordance with the operation of the input section 5 as described above. The angle data set as described above is expressed in correspondence with Table 1 as follows.

Table 1 If you enter the load operation pattern settings in the angle corresponding to the cycle, the operation pattern will be automatically changed according to the cycle and the load will operate with the same operation pattern when only the cycle is changed. It becomes possible to do so.

[Effects of the Invention] As described above, the present invention includes a cycle setting means for setting a cycle at a time and an angle corresponding to the time, an angle setting means for setting the operation pattern at an angle corresponding to the angle of the cycle, Since it is equipped with an arithmetic control means that converts the angle data set by the angle setting means into time data based on the period and controls the operation pattern of the load according to the converted time data, when only 5 periods are changed, The operation pattern can be automatically changed according to the cycle, so there is no need to change the operation pattern of each load.
