Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a multipoint positioning counter device.

(Prior Art) Conventionally, a counter device of this type has been set and displayed mechanically, and therefore has to be upsized. Therefore, actually, only two or three stages can be set.

(Object of the Invention) The present invention has been invented in view of such a situation. By electrically setting and storing a set value, a large number of set points can be obtained, and the apparatus can be downsized. The present invention provides a counter device for multipoint positioning.

(Structure of the Present Invention) FIG. 1 is an overall structure diagram clearly showing the structure of the present invention.

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

The counter counts the count input and has a hardware configuration (discrete configuration).

At least the reset signal, the step signal, and the start signal are supplied to the input circuit.

The process calculation means returns the current process to the initial process by the reset signal supplied via the input circuit, and sends the execution process signal by advancing or retracting the current process by the step signal.

The set value input means is means for inputting each step and the reference set value corresponding thereto and also inputting the displacement amount, and for example, a keyboard or the like corresponds thereto.

The set value storage means stores the set value corresponding to each process. In the present invention, the difference (Ii-ΔI) between the reference set value Ii and the displacement amount ΔI of each process is calculated by the calculating means. The difference is electrically stored as a set value for each process together with the reference set value Iii for each process. RAM is usually used.

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

The comparison means compares the output of the counter and the set value from the data transfer means for the magnitude and the coincidence, and sends out a signal according to the comparison. The comparison means and the data transfer means are operated by supplying a start signal during operation.

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

The mode selection means sends at least a selection signal for selecting the operation mode and the setting mode. The operating mode is a normal operating system, and the setting mode is an operating system for storing each process and its set value in the set value storage means.

The display selection drive means sends the output of the counter at the time of operation and the set value from the data transfer means at the time of setting according to the mode signal from the mode selection means.

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

The process calculation means, the data transfer means, and the display selection driving means are configured by a ROM in which a program is stored in advance and a CPU that operates according to the program. Similar to the above-mentioned means, the comparison means may be configured by a ROM and a CPU, or may be configured by a separate comparison arithmetic unit.

Further, when the mode selection means is selected to the operation mode, all the components except the setting input means are activated, and when the mode is selected to the setting mode, the setting input means and the set value are set. It is preferable to activate the storage means, the data transfer means, the display selection drive means and the display device, but of course the present invention is not limited to this.

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

In FIG. 2, (1) is an addition / subtraction counter, which counts the count input. Further, in relation to FIG. 1, a comparator corresponding to the comparison means is built in. (2) is an input circuit, to which input signals such as a reset signal, a step signal, and a start signal are supplied. (3) is a RAM in which set values corresponding to each process are stored. (4) is a ROM in which a predetermined program is stored. (5) is a CPU and ROM
Various arithmetic operations are performed according to the program of (4).
The CPU (5) constitutes a process calculation means, a data transfer means, and a display selection drive means in relation to FIG. (6) is an output circuit, which sends a control output to the outside based on the comparison result of the comparator in the counter (1) via the CPU (5). (7) is a display, which displays the execution process and the output or set value of the counter (1). (8)
Is a keyboard and is mainly used for writing setting values in RAM (3). This keyboard (8) is
In relation to the figure, it constitutes a set value input means.
(9) is a cassette interface, which writes a set value to RAM (3) by reproducing input from the outside,
Alternatively, it is used for recording the set value of the RAM (3) as a recording output on an external magnetic tape or the like. (10) is a mode selection switch, which is used to select various modes.

The operation of the multipoint positioning counter device having the above configuration will be described with reference to the flow chart of FIG.

Here, a case where the mode selection switch (10) is selected as the operation mode will be described as an example. The details of this mode will be described later.

(1) When the mode is selected as the operation mode, the control input is fetched to 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 is returned to the initial state.

(3) When the control input is a step signal, the execution process is moved forward or backward by one.

(4) When the control input is a start signal, the set value corresponding to the execution process is compared with the counter output of the addition / subtraction counter (1).

(5) The comparison of the above (4) is performed for small and large and one step. For example, if the comparison is large, a direction instruction is displayed on the display (7) and a direction control signal is sent via the output circuit (6). . On the contrary, if it is small, the direction instruction and the control signal are given to the display (7) and the output circuit (6) respectively.

(6) When the set value and the output of the counter (1) match according to the step (4), a match output is sent to the output circuit 6. Then, the process returns to step (1) again.

By repeating the above steps, the counter (1)
The control output is sent out from the output circuit 6 every time the output of the above-mentioned value coincides with the set value corresponding to each process. In the above-mentioned flow chart, the "stop" is not shown and the flow chart is endless. This is because this embodiment shows an endless case in which the process returns to the first process after the final process. .

Unlike the conventional counter device, the RAM (3) can store a large number of setting values, and auxiliary data for positioning is also written therein. For example, certain step (i)
If the set value of is Ii, then use the keyboard (8)
When the value of Ii is input, ΔI ₁ and ΔI ₂ are also input, these data are written in the RAM (3), the set value is read from the RAM (3), and then Ii-ΔI ₁ in the CPU (5). , Ii−ΔI ₂
It is also possible to carry out the calculation of, and to set not only one set value corresponding to the execution process but also three set values. With this configuration, the control signal corresponding to each of the above set values is sent to the external device, and fine and appropriate positioning control can be performed.

In the description of the flow chart above, the case where the mode is selected as the operation mode has been described, but this mode selection is, so to speak, the operation of the CPU (5), that is, the ROM (4).
Program is selected, and various modes can be selected as required.

Regarding this mode, in addition to the above operation mode, it is possible to provide each mode of stop, adjustment, setting, tracing setting, and cassette. The stop mode is for stopping the entire apparatus, and the adjustment mode is for changing the set values of the RAM (3), and the changed data is written in the RAM (3) by the keyboard (8) while the operation is continued. In the setting mode, the setting value is written in the RAM (3). The profile setting is the output of the counter (1) at that time according to the actual product.
Write to RAM (3). In the cassette mode, the following operation is performed via the cassette interface (9). In other words, when many devices such as machine tools manufacture the same parts, it is sufficient to write the same set values to the RAM of each device, so after recording that data once on the magnetic tape, the cassette interface It can be written to the RAM (3) via the face (9). Further, the contents of the RAM of a certain device can be written in 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 improved.

(Effects of the Invention) As is apparent from the above description, the multipoint positioning counter device according to the present invention has the advantage of being able to set a large number of setting values corresponding to each process and of downsizing the entire device. Further, the difference (Ii−ΔI) between the reference set value Ii and the displacement amount ΔI of each process is electrically stored as the set value of each process together with the reference set value Ii of each process. Auxiliary data for each process can be obtained simply by inputting, and the work of inputting set values becomes easy. In addition, since the counter has a hardware configuration, high-speed counting is possible.
