Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a multi-stage setting type counter device.

(Prior Art) Conventionally, this type of counter device has been forced to be large in size because its setting values have been mechanically set and displayed, and therefore, in practice, only two or three steps can be set.

(Objective of the Invention) The present invention was invented in view of the above situation, and by electrically setting and storing set values, a large number of set points can be obtained, and operation can be performed from any process. The present invention provides a counter device that can be started easily and that also enables miniaturization of the device.

(Configuration of the present invention) FIG. 1 is an overall configuration diagram clearly showing the configuration of the present invention.

The counter device of the present invention includes the following counter, input circuit, process calculation means, set value input means,
It is composed of a storage means, a data transfer means, a comparison means, an output circuit, a mode switching means, a display selection driving means, and a display device.

The counter counts the count input,
It consists of a hardware configuration (discrete configuration).

The input circuit is supplied with at least a reset signal, a step signal, a start signal and a start process signal. The start process signal is a signal that designates the first process and is constantly input. For example, if the process starts from the first step, a numerical signal corresponding to the first step is input. In addition, if it is necessary to return to (or skip) a specific process, for example, the Nth process, after the process advances or retreats one step at a time, the Nth
Input the numerical signal corresponding to the th process.
For example, when operation patterns for several types of stop positions are required, the settings must be changed each time the operation pattern changes, but by providing a start process signal input, all operation patterns can be memorized from the beginning. , a major feature is that the pattern can be selected from outside the counter. The reset signal is a signal for resetting an output circuit and a process counter, which will be described later. When the process counter is reset, the start process signal is read and the corresponding numerical signal is set in the counter. This will be described in detail in the examples described later. The step signal is for increasing or decreasing the value of the process counter. In other words, when moving the process forward one step at a time, a step signal is applied without adding a signal to the step direction designation input, and when moving the process backward one step at a time, a signal is added to the step direction designation input. Add step signal. The start signal is a signal for instructing the start of execution of the process set in the process counter.

Here, to describe the relationship among the above signals, as mentioned above, the start process signal is always inputted, and when the device is started for the first time, it is inputted in the order of reset signal → step signal → start signal. After activation, the step signal is input in the order of activation signal. Also, when returning to a specific process (or skipping), input the start process signal corresponding to that process, and then input the reset signal → step signal at an appropriate timing. A numerical value corresponding to the process is set in the process counter. Then, when the activation signal is input, the operation starts from the step described above.

The process calculation means sends out signals based on various control signals supplied via the input circuit. For example, when a reset signal is input, it is sent as is to the process counter and the process counter is reset. When the step-up signal is input, it is determined whether the process counter is in a reset state or not, and if it is not reset, a signal is sent to increase or decrease the value of the counter by one. If it has been reset, it reads the start process signal and sends out a signal for setting the corresponding numerical signal in the process counter. When the start signal is input, it is determined whether the process counter is in a reset state or not, and if it is not reset, the value set in the process counter, that is, a signal instructing to execute the process is sent out.

The setting value input means is a means for inputting each process and its corresponding setting value, and is, for example, a keyboard.

The storage means includes a process counter and a set value storage means, and is composed of RAM.

The process counter is reset based on a reset signal from the process calculation means, sets the corresponding process based on the start process signal, and adds or subtracts the count value based on the step signal. Then, based on the activation signal, the current count value, that is, the set value corresponding to the process is read from the set value storage means.

This process counter exists in the working area of RAM.

The set value storage means stores the set value signal from the set value input means, and stores one or more set values corresponding to each process. Then, the corresponding setting value is sent out based on the instruction from the process counter.

The data transfer means stores the setting signal from the setting value input means in the setting value storage means, and sends the signal from the process calculation means to the process counter.
It also reads out and sends out the setting value corresponding to the execution process set in the process counter.

The comparison means compares the output of the counter and the setting value from the data transfer means in terms of magnitude and coincidence, and sends out a signal according to the comparison. Note that the comparison means and data transfer means are activated by supply of a start signal during operation.

The output circuit sends out a control output based on the output of the comparison means.

The mode selection means sends out a selection signal for at least an operation mode and a setting mode. The operation mode is a normal operation system, and the setting mode is an operation system in which each process and its set value are stored in the set value storage means.

The display selection driving means sends out the output of the counter during operation, and sends out the set value from the data transfer means during setting, depending on the mode signal from the mode selection means.

The display device displays the output or setting value of the counter based on the output from the display selection driving means, and also displays the execution process. This display is usually a digital value.

Note that the process calculation means, data transfer means, and display selection driving means described above operate according to a ROM in which a program is stored in advance and the program.
It is composed of CPU. The comparison means may be composed of a ROM and a CPU in the same way as the above-mentioned means, or may be composed of a separately installed comparator.

Furthermore, when the mode selection means is selected as the operation mode, all components other than the set value input means are activated, and when the setting mode is selected, the set value input means and the storage means are activated. , the data transfer means, the display selection drive means, and the display device are preferably activated, but of course the invention is not limited thereto.

(Embodiment) FIG. 2 is a block diagram of a counter device according to an embodiment of the present invention, and FIG. 3 is a flowchart showing its operation.

In FIG. 2, 1 is an addition/subtraction counter;
Count count input. Furthermore, in relation to FIG. 1, a comparator corresponding to comparison means is built-in. Reference numeral 2 denotes an input circuit to which input signals such as a reset signal, step signal, start signal, start process signal, etc. are supplied.
A RAM 3 constitutes a process counter and a set value storage means, and stores each process and set values corresponding to each process. 4 is a ROM in which a predetermined program is stored. 5 is the CPU,
Various arithmetic operations are performed according to the programs in ROM4. In relation to Figure 1, this CPU5 is:
It constitutes a process calculation means, a data transfer means, and a display selection means. 6 is an output circuit, and CPU5
A control output is sent to the outside based on the comparison result of the comparator in the counter 1. 7 is a display, which displays the execution process and the output or set value of the counter 1; 8 is the keyboard, mainly
Used to write setting values to RAM3. In relation to FIG. 1, this keyboard 8 constitutes a set value input means. 9 is a cassette interface, which receives external playback input.
Write the setting value to RAM3, or
It is used to record the setting values of RAM3 on an external magnetic tape etc. as a recording output. 10 is a mode selection switch, which is used to select various modes.

The operation of the counter device having the above configuration will be explained based on the flowchart of FIG. 3.

Here, a case where the mode selection switch 10 is selected to the driving mode will be described as an example.
Note that details of this mode will be described later.

(1) When the mode is selected as the operation mode, control input is taken into the CPU 5 via the input circuit 2.

(2) When the control input is a reset signal, all outputs of the output circuit 6 are reset and the process counter is reset.

(3) Next, when a step signal is input, the process calculation means determines whether the process counter has been reset.

(4) Here, since the process counter has been reset, the start process signal is read by the process calculation means. Then, the process value corresponding to this signal is set in the process counter.

(5) Next, when the start signal is input, it is determined whether the process counter is set or not.

(6) Here, since the process counter has not been reset, the set value corresponding to the count value of the process counter is read from the set value storage means.
The set value is sent to the comparison means via the data transfer means.

(7) The comparison means compares the set value corresponding to the execution step and the output of the addition/subtraction counter 1.

(8) The comparison in step (7) is performed for magnitude and coincidence. For example, if the comparison is large, a direction instruction is displayed on the display 7 and a direction control signal is sent out via the output circuit 6. Conversely, if it is small, the direction instruction and control signal are sent to the display 7 and output circuit 6, respectively. When the set value and the output of the counter 1 match, a matching output is sent to the output circuit 6.

(9) Next, when the step signal is input, the process calculation means determines whether or not the process counter has been reset.

(10) Here, the process counter has not been reset, so either add one to the count set in the process counter, that is, the process value, or
Or subtract one to move the process forward or backward.

(11) Next, when the activation signal is input, steps (5) to (8) are performed.

Thereafter, steps (9) to (11) are repeated.
When changing the process flow, that is, instead of moving the process forward or backward one step at a time,
For example, if a process is to be started three steps after the execution process, a corresponding start process signal is input in advance, and a reset signal is input at the timing when the execution process is completed. This starts the operations from step (1) onwards.

Therefore, in the flowchart of FIG. 3, when a reset signal is input, the process proceeds in the order A→B→C, and in other cases, the process proceeds in the order B'→C.

In addition, in the above flowchart, "stop" is not shown and it is endless, but this is because this example shows an endless case in which the process returns to the first process after the final process. .

RAM3 is different from conventional counter devices,
Since a large number of setting values can be stored, for example, when the counter device of this embodiment is used as a multi-point positioning device, arbitrary auxiliary data for positioning control can also be written. For example, if the setting value of a certain process i is I _i ,
When the value of I _i is entered using the keyboard 8, ΔI ₁ ,
After inputting ΔI ₂ , writing these data to RAM3, and reading the set value from RAM3,
The CPU 5 calculates I _i −ΔI ₁ and I _i −ΔI ₂ ,
In addition to setting only one setting value corresponding to the execution process,
You can also make it three. In this way, control signals corresponding to each of the above-mentioned setting values are sent to an external device, making it possible to perform fine and appropriate positioning control.

In addition, in the explanation of the above flowchart, the case where the mode is selected as the operation mode was explained, but the selection of this mode is to select the operation of the CPU 5, that is, the program of the ROM 4, and various changes can be made as necessary. It is also possible to select a mode.

Regarding this mode, if the counter device of this embodiment is used as a multi-point positioning counter, it is conceivable to provide each mode of stop, adjustment, setting, profile setting, and cassette in addition to the above operation modes. . The stop mode is for stopping the entire device, and the adjustment mode is for changing the set values of the RAM 3, etc., and writing the changed data into the RAM 3 using the keyboard 8 while the operation continues. In setting mode, setting values are written to RAM3. In the tracing setting, the output of counter 1 at that time is written to RAM 3 according to the actual item. In the cassette mode, the following operations are performed via the cassette interface 9. In other words, when many pieces of equipment, such as machine tools, manufacture the same part, it is sufficient to write the same setting values to the RAM of each piece of equipment. The data can be written to the RAM 3 via the face 9. moreover,
It is also possible to write the contents of the RAM of one device to the RAM of another device via the cassette interface 9.

By providing various modes as described above, various operations can be performed and versatility can be increased.

(Effects of the Invention) As is clear from the above description, the counter device according to the present invention has the advantage that a large number of set values corresponding to each process can be set, and the entire device can be made smaller. In addition, since the counter has a hardware configuration, high-speed counting is possible.

Furthermore, if multiple positioning patterns are stored in advance by providing a start process signal input that can start from any process, it is possible to select which positioning pattern to execute using a switch or the like from outside the counter. The big advantage is that it can be done.
