Description

[Detailed description of the invention] (Technical field of invention) The present invention relates to a multi-stage setting type counter device.

(Prior art) Conventional stone counters had to set and display the setting values mechanically, so they had to be large in size, and therefore, in reality, there were only counters that could set G degrees in 2 to 3 steps. .

(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 an arbitrary process can be performed. The object of the present invention is to provide a counter device which can operate from the beginning and which also enables miniaturization of the tear.

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

The counter device of the present invention includes a counter, an input circuit, a process calculation means, a set value input means, a storage means, a data transfer means, a comparison setting, an output circuit, a mode switching means, a display selecting means, and a display described below. It is composed of devices.

The O input circuit, which is a counter and counts inputs and is made of a hardware configuration (discrete configuration), is supplied with at least a reset signal, a step signal, a start signal, and a start process signal. The starting process signal is a signal that specifies the first process, and is constantly controlled by humans. For example, it starts with the first knee, and I input a numerical signal corresponding to it. Also, after the processes are sequentially advanced or retracted by one process, a specific process, for example N
If it is necessary to return to (or skip) the Nth process, input a numerical signal corresponding to the Nth process.

For example, when you need a movement pattern for the stop position of some 4 MIs, you have to change the settings every time the movement pattern changes, but despite having six-way start process signals, you can memorize all movement patterns from the beginning. Another great feature is that the pattern can be selected outside of the counter. When the reset signal is set, the start signal is read and the corresponding numerical signal is sent to the counter. This will be explained in detail in the example below. The step signal is a signal for moving the machine forward or backward one step at a time by increasing or decreasing the value of the step counter. The start signal is an Ig signal for instructing the start of the completion of the process set in the process counter.

Here, to describe the relationship between the above signals, in the above-mentioned process, the start process signal is always inputted, and the first time the device is started, it is 59J.
When you want to activate it, you can input it in the following order: reset signal → step signal → start signal. After startup, inputs can be made in the order of step number and start signal. If you want to return to the fixed process at 4゛ (or skip it), input the start process signal corresponding to that process θ to 0, then at an appropriate timing, reset the process d → When the step signal is input, Nrl (iij) corresponding to the aforementioned process is set in the process counter. Then, when the °C1 start signal is input, the operation starts from the aforementioned process.

The process calculation means sends out a signal based on each control signal supplied via the input circuit. For example, when a reset signal is input, it sends it as it is to the process counter.
1 Reset the counter.

When an increment 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 increment or decrement the value of the counter by one. If it is reset, it reads the start process 1h1 signal and sends a signal to set the fC numerical signal in the process counter.When the 0 activation signal is input, it is determined whether the process counter is in the reset state. If it has not been reset, it will send out the fC value, that is, the number 47 (number 47) instructing to fire the process.

The set value input means is a means for inputting each process and the corresponding set value, and a keyboard or the like corresponds to the VC.

The storage means includes a process counter and a set value storage means,
You can save money in RAM.

The process counter is reset based on the reset signal from the kingdom calculation means, sets the corresponding process based on the start process signal, and increments 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 number 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 set value input means in the set value storage means, and also sends the (W) from the process calculation means to the process counter.

'f'fc1 Reads and sends the setting value corresponding to the execution process set in the food counter.

A signal is sent out according to the comparison. No, this comparator f7. When driving, connect L+ and data transfer means.
Acts upon supply of start signal.

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

The mode selection means sends out a selection signal between at least an operation mode and a setting mode. The operation mode is the normal operation system, and the setting mode is the storage of each process and its setting value in the setting value storage means. It is a motion system that allows

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, in accordance with each mode number from the mode selection means.

The receiving device displays the output or set value of the counter in addition to the output from the display selection driving means, and also displays the execution process. This display is usually digital (displayed as a y value).

Note that the above process calculation means 1. The data transfer means and display selection driving means are 7tROM in which programs are stored in advance.
and the CPU that operates according to the program. Similar to the above means, the comparison means is ROM and C
It may be configured by working with the PU, or it may be configured by a separate comparison calculator.

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 driving means, and the display device are preferably activated/stated, but the present invention is of course not limited to this.

In relation to FIG. 1, (11) constitutes a set value input means. (9) is a cassette interface, which allows setting values to be written to RAM (3) by external playback input, Alternatively, it is used to record the set value of the RAM (3) as a recording output onto an external magnetic tape, etc. 00 is a mode selection switch, which is used to select various modes.

The operation of the above-mentioned four-take counter device will be explained based on the flowchart shown in FIG.

Here, an example will be explained in which the mode selection switch 4 is selected to the driving mode. Note that details of this mode will be described later.

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

(2) When the control input is a reset signal, the output circuit (6
) and reset the 1-step counter.

(3) Next, when a multiple communication number 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.

(6) Here, since the process counter has not been reset, the setting value corresponding to the count value of the kingdom counter is read from the setting 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 size and one stage. For example, if the size is large, an instruction for the ■ direction is displayed on the display (7), and the
Sends direction control signals. On the other hand, if it is small, the instruction and control signal in the direction of θ 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.

αQ Here, since the process counter has not been reset-F, the count number set in the process counter,
That is, the process value is added by 1 or subtracted by 1 to move the process forward or backward.

α sword Next, when the activation signal is input, the above (51 to (8)
) steps are taken.

Thereafter, steps (9) to α1) are repeated.

Then, when changing the flow of the process, that is, changing the process to 1
For example, if you want to start the process three steps after the execution process instead of moving it forward or backward step by step, input the 7'C start process signal in advance and execute the process. Input a reset signal at the timing when the process is completed. This starts the operations from step (1) onwards.

Therefore, in the flowchart of FIG. 3, when the reset Nobushima is inputted, the process proceeds in the order of A −+ 33→C, and in other cases, the process proceeds in the order of B'→C.

Note that ``stop'' is not shown in 70-Char) of the above, but it is endless, because this example shows an endless case in which the process returns to the first process after the final process. It is.

RAM (3) 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 work 8 (1) is Ii, the keyboard (8) is
After inputting the iO value, input Δ11°ΔI, write these data to RAM (3), and
After reading the set value from (3), the CPU (5) calculates Ii - ΔI, , Ii - ΔI2, and the set value corresponding to the execution process can be set to three instead of just one. can. If you do this, each of the above settings (f
A control signal corresponding to O is sent to an external device, allowing fine and appropriate positioning control.

In the explanation of the 70-chart above, the case where the mode is selected as the operation mode is explained.
OM (4) program is selected, and various modes can be selected as required.

Regarding this mode, when the counter device of this embodiment is used as a multi-point positioning counter, in addition to the above operation modes, each of the four modes of stop, adjustment, setting, tracing setting, and cassette can be provided. Conceivable. The stop mode is for stopping the entire device, and the adjustment mode is for R.
This is to change the setting values of A M (3), etc., and the changed data can be RA'd using the keyboard (8) while operation continues.
Enter 8 into MC3).

In the setting mode, the set value is written in the RAM (31). In the profile setting, the output of the counter (1) at that time is written in the RAM (3) according to the actual item. In the cassette mode, the setting value is written in the RAM (3). In other words, when many pieces of equipment are used to manufacture the same part, such as a machine tool, the following operations are performed:
Since it is only necessary to write the same setting value in AM, the data can be once recorded on the magnetic tape and then written into RAM (3) via the cassette interface (9). Furthermore, the contents of the RAM of one device can be written 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 is made of hard CR, high-speed counting is possible.

If the positioning pattern of the mantissa is stored in advance by providing a start process signal input that can start from any process, it is possible to easily specify which positioning pattern to execute when performing a counter external operation such as 9-sinch. There is a strong starting point that you can choose.
