The general resistance welding measuring apparatus is provided with the operation panel for setting and inputting measurement or monitoring conditions (upper and lower limits of current, upper and lower limits of time, etc.) or displaying measurement values of welding conditions on the front or front of the apparatus.

In the conventional operation panel of this type of apparatus, switches, keys or buttons (hereinafter collectively referred to as "switches") for selecting respective items such as welding conditions and monitoring conditions or for inputting set values for each item. Many are set. In such an operation panel, for example, when setting or inputting a measurement or monitoring condition, the program switch is operated to switch to the program mode screen, and the corresponding item switch or to select each item from the program mode. If the user does not manually operate the various switches in a predetermined order, such as operating the switch and operating the increment switch and / or the decrement switch to set and enter a desired value for the selected item. Can not be done.

As described above, in the conventional resistance welding measurement apparatus, since a large number of switches are arranged on the operation panel, it is difficult to reduce the area of the operation panel, and furthermore, there is a problem that the size of the device unit is limited. In addition, in promoting the miniaturization of the operation panel, it is necessary to make individual switches inevitably small, and in doing so, it is not convenient for writing by allowing the user to perform small and complicated switch operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and an object thereof is to provide a resistance welding measuring apparatus which simultaneously realizes miniaturization of the operation panel and improvement of operability.

In order to achieve the above object, the resistance welding measuring apparatus of the present invention sets and inputs a predetermined measurement or monitoring condition in resistance welding through an operation panel provided on one surface of the device, and measures the measured value of the predetermined welding condition.

A second switch operation input processing means for sending or decreasing by way of example, and in response to the third switch operation, determine a selectable item or numerical value at the time on the display, and enter into the mode of the determined item; or It is set as the structure which has the 3rd switch operation input processing means which sets and inputs the determined numerical value.

In the above configuration, it is possible to selectively perform the first, second and third switch operations with one switch, and to sequentially send selectable items on the display or to increase numerical values by the first switch operation. By the second switch operation, it is possible to send the selectable items on the display in reverse order or to decrease the numerical values.The third switch operation confirms the corresponding items on the display and enters the mode of this item, or displays It is possible to enter the settings after confirming the corresponding value on the screen.

In the resistance welding measurement device of the present invention, preferably, the switch may be configured to be able to be pressed at least rightwardly, leftwardly, and elastically. In this case, the operation of turning the switch to the right is the first switch operation, the operation of turning the switch to the left is the second switch operation, and the operation of pressing the switch to the first condition is performed. The switch operation of 3 may be used. Alternatively, the operation of turning the switch to the left is the first switch operation, the operation of turning the switch to the right is the second switch operation, and the operation of pressing the switch to the first condition is the third operation. The switch operation may be performed.

In the first or second switch operation, the operation of turning the switch at a predetermined angle may be a switch operation of one unit. For example, each time the switch is turned to the right at a predetermined angle, the selectable items or numerical values may be sent one by one or increased by one.

The third switch operation may be preferably defined as an operation of pressing the switch once within a predetermined time. Further, from the pressing function of the switch according to the present invention, an operation of pressing the switch once for a predetermined time or more and a pressing operation of the switch several times within a predetermined time can also be performed. Therefore, from these two types of pressing operations, for example, an input process for switching the screen between the screen for setting the measurement or monitoring conditions on the display and the screen for performing the resistance welding, or the welding on the display. It is also possible to obtain an input process for switching the screen between the screen for displaying the measured value of the condition and the screen for displaying the set value of the measurement or monitoring condition.

Item lamps such as ANGL (current conduction angle), COUNT (count of RBI), SCH (schedule), STATUS (status), and PRG (program mode to execution mode switching) It is arranged.

The switch 14 is the only switch provided on the operation panel 10, has a disk-like shape, and can turn right (clockwise), turn left (counterclockwise), and press firmly with respect to the panel surface. It is configured to. In the vicinity of the outer circumference of the switch 14, in order to ensure stable and reliable rotation operation, a radial protrusion 14a for slipping is formed at regular angular intervals. In addition, on the upper surface of the switch 14, a recess 14b for the fingertips that is thinly curved at several off-set portions in order to ensure stable right turn or left turn operation is provided. Formed.

2 shows the functional configuration of this resistance welding measuring apparatus. The switch operation in the switch 14 is detected or identified by the switch input circuit 30 in the device unit, and the switch input signal corresponding to each switch operation is switched from the switch input circuit 30 to the switch input processing unit 32. Is given by The current sensor 34 is provided in the conductor 36 of the resistance welder through which the welding current (or current corresponding thereto) I to be measured flows. The output signal of this current sensor 34 is supplied to the measuring circuit 38 in the device unit via an electric cable, and the measuring circuit 38 obtains the measured value of current I or the measured value of energization time, and the measured value data is measured and stored. It is stored in 40.

The switch input processing section 32 is, for example, made of a CPU and executes all switch input processing in the apparatus in accordance with various programs held in the program storage section 42. In addition to the switch input circuit 30, the measurement memory unit 40, and the program memory unit 42, the switch input processing unit 32 includes a setting memory unit 44, a display unit 46, and a mode management unit 48. ) Is also connected.

The setting memory 44 stores the setting values of various setting or monitoring conditions which have been set and input via the operation panel 10. The display unit 46 includes a display control circuit related to a display function in addition to including the display unit 12 on the operation panel 10. The mode manager 48 responds to the inquiry from the switch input processing unit 32 with respect to the mode currently selected by the apparatus, and displays the operation history of the switch 14 and the mode status of the current time (display). Screen content).

In FIG. 3, the whole procedure of this switch input processing part 32 is shown according to the operation type of switch 14 in this embodiment. In the switch 14, five kinds of switch operations are possible. More specifically, "right turn operation" and "left turn operation" are possible in a configuration capable of turning right and left, respectively, and "single press operation", "long press operation" and "two times" in a configuration that can be pressed elastically. Continuous pressing operation ”.

In the " right turn operation " or " left turn operation ", each time the switch 14 is rotated by a predetermined angle (for example, 15 °), a switch input signal of one unit (right turn operation or left turn operation detection) is detected from the switch input circuit 30. Signal) is output. In the "one push operation", when the switch 14 is pressed once within a predetermined time (for example, one second), a switch input signal of one unit from the switch input circuit 30 (one push operation detection signal) ) Is output. In the "long press operation", when the switch 14 is pressed for a predetermined time (for example, 1 second) or more, one unit of switch input signal (long press operation detection signal) is input from the switch input circuit 30. It is supposed to be output. In the " two consecutive pressing operations ", when the switch 14 is continuously pressed twice within a predetermined time (for example, 1.5 seconds), a switch input signal of one unit from the switch input circuit 30 (two consecutive times) Operation detection signal).

As shown in Fig. 3, when the power is turned on, a predetermined initialization process (step A1) is performed, and the initial screen is displayed on the display unit 12 of the operation panel 10, and the switch operation in the switch 14 is performed. This can be accepted or enabled (step A2). Thereafter, in response to an arbitrary switch operation, an input process was performed in accordance with the mode or situation at each time point. That is, by the switch input process 32, the right turn operation input process①, the left turn operation input process②, the one press operation input process③, and the second continuous press operation input process④ and the long time according to the above five kinds of switch operations, respectively. The push operation input process 5 is executed.

4 shows the procedure of the right turn operation input processing ① in the switch input processing section 32. In this input processing ①, in response to the "right turn operation" of the switch 14, the query is first made to the mode manager 48 to recognize or confirm the mode status (display screen contents) of the current time (steps B1, B2, and B3). ). The resistance welding control apparatus in this embodiment prepares a "program" mode and a "execution" mode as an upper mode, and operates in either of these two upper modes.

In addition, under the "program" mode, various sub-modes are prepared, and the "right turn operation" is effectively accepted in the "item selection" mode and the "numeric input" mode. Thus, as described later with reference to Figs. 9 to 11, when the "right turn operation" is performed in the "numeric input" mode under the "program" mode, the display unit 12 increments the numerical value of the blinking position. (Step B4). When the "right turn operation" is performed in the "item selection" mode under the "program" mode, the selectable items are sent in order on the display unit 12 (step B6).

In addition, under the "execution" mode, various sub-modes are prepared, and the "right turn operation" is effectively accepted in the "schedule number selection" mode, the "item selection" mode, and the "set value display" mode. Thus, as described later with reference to FIG. 12, under the "execution" mode, when "right turn operation" is performed in the lower "schedule number selection" mode, the numerical value (schedule number) of the blinking position is incremented ( Step B6). When the "right turn operation" is performed in the "item selection" mode, the display unit 12 sends the selectable items in order (step B7). When "right turn operation" is performed in the "set value display" mode, the display unit 12 sends the items of the set value display in order (step B8).

5 shows a procedure of the right turn operation input process ②. In this input process ②, the switch 14 responds to the " left rotation operation " to perform a symmetrical process with the above right rotation operation input process ①. That is, "decrement" is performed instead of "increment" for numerical values, and "send in reverse order" instead of "sending in order" for the items.

6 shows the procedure of the single push operation input process ③. In this input processing ③, the "one push operation" is effectively accepted in the "program" mode in the lower "item selection" mode or "numeric input" mode. However, as will be described later with reference to Figs. 9 to 11, under the "program" mode, when the "one push operation" is performed in the "numerical input" mode, the display unit 12 responds (flashing). Confirm the numerical value of (step D4). In addition, when the "one push operation" is performed in the "item selection" mode, the display unit 12 selects the item (during lamp lighting, etc.) and enters the setting mode of the item (step D5). .

In addition, under the "execution" mode, the "one push operation" is effectively accepted in the lower "schedule number selection" mode or the "schedule" mode. However, as will be described later with reference to FIG. 12, under the "execution" mode, when the "one-time operation" is performed in the "schedule number selection" mode, the schedule number of the corresponding (flashing) is determined and inputted (step). D6). When the "one push operation" is performed in the "schedule" mode under the "execution" mode, the lower mode is switched to the "schedule number selection" mode (step D7).

7 shows a procedure of the long time push operation input process ④. In this input processing (4), the "long press operation" is effectively accepted as the lower mode of "high mode switching", that is, "program mode to execution mode switching" in both "program" mode and "execution" mode. As will be described later, switching from the "program" mode to the "execution" mode or from the "execution" mode to the "program" mode is performed (steps E5 and E6). If "long press operation" is performed in a mode other than "program mode to execution mode switching", it is invalidated (steps E4 and E7).

8 shows the procedure of the second continuous pressing operation input process 5. In this input processing (5), the "continuous pressing operation" is effectively accepted in the "set value display" mode or the "measured value display" mode under the "execution" mode, and the set value display will be described later with reference to FIG. In the "measured value mode" from "" mode, or from the "measured value mode" mode to the "set value display" mode (steps F3 and F4). Under the "Program" mode, "continuous press operation" is invalid (step F5).

Next, with reference to FIGS. 9-11, the input and display function on the operation panel 10 in this embodiment are demonstrated.

9 shows an example of switch operation and screen display of the display unit 12 when setting and inputting a schedule number in the " program " mode. Here, the schedule number is a management code for collectively managing a set of measurement or monitoring conditions. For example, when preparing schedule numbers 1 to 31, 31 sets of conditions can be set.

In the screen of Fig. 9A, the "SCH" lamp is lit on the mode setting display unit 20, and an item of "SCH" (schedule) can be selected. In this scene, when the "one push operation" of the switch 14 is performed, it enters into the mode of the "SCH" item, that is, the schedule number setting mode (step D5 in FIG. 6), and as shown in FIG. 9B. In the same manner, the numerical value (condition number) in the alphanumeric display section 26 of the mode setting display section 20 blinks to enter the numerical input mode relating to the schedule number. In this state, when the "right turn operation" of the switch 14 is performed, the schedule number in blinking is incremented (step B4 in FIG. 4). In addition, when the "left turn operation" of the switch 14 is performed, the schedule number which is flashing is decremented (step C4 in FIG. 5). Then, when the "one push operation" of the switch 14 is performed, the schedule number displayed at that time is determined (setting input) and does not blink (step D4 in FIG. 6), and in FIG. Return to the state.

In the screen of FIG. 9A, when the "right turn operation" of the switch 14 is performed, the mode is sent to the mode of the next item determined in advance, for example, the mode of the "LAST" item for energization time (FIG. 4). Step B5). At this time, the "SCH" lamp is turned off, and as shown in FIG. 10A, the "LAST" lamp of the time setting display unit 18 lights up.

In the screen of FIG. 10A, when the "one-time pressing operation" of the switch 14 is performed, the input is made to the setting mode of the "LAST" item (step D5 in FIG. 6). In this example, since "CYC" (cycle) is set or selected in advance as a unit of "LAST", the cycle is set to the LAST cycle setting mode as shown in Fig. 10B, and the "CYC" lamp is turned on. As shown in Fig. 10A, the mode setting display section 20 displays a schedule number ("1" in the example shown in the drawing) that was set earlier. In other words, it is indicated that the desired LAST cycle is set under this schedule number ("1").

In the LAST cycle setting mode, the numbers in the first lowest row blink and the flashing numerical value is incremented or decremented in accordance with the "right turn operation" or "left turn operation" of the switch 14 (step B4 in FIG. 4). Or step C4 of FIG. 5). When the "one push operation" of the switch 14 is performed, the numerical value of the lowest column displayed at that time is decided (setting input) and it does not flash already (step D4 of FIG. 6), but instead of The heat flashes. The numerical values of the respective columns are sequentially determined from the lower columns in the same order as described above, and the desired LAST cycle is determined and input at the time when the numerical value of the last highest column is determined, and the screen returns to the screen (A) of FIG.

The LAST cycle is the end of the measurement section for the energization time expressed by a cycle of a predetermined frequency (for example, 50 Hz). In this connection, the FIRST cycle is the start of the measurement section for the energization time indicated by the cycle.

Also in the screen of FIG. 10A, when the "right turn operation" of the switch 14 is performed, the mode is sent in order to the next predetermined mode, for example, the "FIRST" item for time setting (step of FIG. 4). B5). At this time, the "LAST" lamp is turned off, and the "FIRST" lamp is lit instead (not shown). When the left turn operation of the switch 14 on the screen of FIG. 10A is performed, the previous item, that is, the above-described "SCH" (schedule) item, is sent in the reverse order (step C5 in FIG. 5).

As described above, in the "program" mode, a desired schedule number can be set or selected, and various measurement or monitoring conditions can be set and input in order under the set schedule number. In the screen shown in FIG. 11A, the "LOW" lamp of the current setting display unit 16 is turned on in the "program" mode, and the lower limit value of the welding current can be set and input. In this state, when the "one push operation" of the switch 14 is performed, it inputs into the setting mode of the "LOW" item for welding current, ie, the current lower limit setting mode, as shown in FIG. Step D5).

In this current lower limit value setting mode, a desired current lower limit value is set and input in the same manner or in the same manner as in the LAST cycle setting mode (Fig. 10 (B)) for the energization time.

FIG. 12 shows an example of input processing and screen display related to the mode setting display unit 20 of the display unit 12 in the " execute " mode. In the "execution" mode, before performing resistance welding, the "SCH" (schedule) item in the mode setting display section 20 is selected by "right turn operation" or "left turn operation", and "single press operation". If this is done, it can be entered in the "schedule number selection" mode (step D7 in FIG. 6), and a desired schedule number ("16" in the example in the figure) can be selected here (steps B6 in FIG. 4 and FIG. 5). Step C6, step D6 in Fig. 6). When the schedule number is selected, all the measurement or monitoring condition setting values collectively managed by the selected schedule number ("16") are retrieved from the setting memory 44.

As shown in Fig. 12, when the item of "PRG" (program mode-execution mode switching) in the mode setting display section 20 is selected by the "right turn operation" or "left turn operation", and the "long press operation" is performed. , The mode is changed from the "execution" mode to the "program" mode (step E6 in FIG. 7). On the contrary, when the item of "PRG" (program mode ↔ execution mode switching) is selected under the "program" mode and "long press operation" is performed, the operation mode is changed from the "program" mode to the "execution" mode (step of FIG. 7). E5).

As shown in Fig. 12, when an item of "COUNT" (the number of RBIs) is selected, the number of RBIs at this time ("132" in the example of the figure) is displayed, and the value of "C.ANGL" (current conduction angle) is displayed. If the item is selected, the current conduction angle ("126 °" in the drawing) is displayed. If the item "STATUS" (status) is selected, the method of resistance welding is applied (AC method "AC" in the drawing). ) Is displayed.

13 shows an example of input processing and screen display for the current setting display unit 16 and the time setting display unit 18 of the display unit 12 in the " execute " mode. When one resistance welding is performed with a resistance welding machine, the current sensor 34 and the measuring circuit 38 measure the welding current or the energizing time in the resistance welding and at the currently selected schedule number. Depending on the measurement or monitoring conditions under control, a positive or negative plate for the welding current measurement or the energization time measurement is also performed. This quantity determination may be performed by the measuring circuit 38, for example.

Such measurement values and determination results are displayed on the current setting display section 16 and the time setting display section 18 under the "measurement value display" mode as shown in FIG. In the example of the figure, the welding current measurement value is 12.00 kA and the determination result is "NOM" (normal), and the energization time measurement value is 19.5 cycles, and the determination result is "NOM" (normal).

In this " measured value display " mode, once the " twice continuous pressing operation " of the switch 14 is performed, the display of the entire screen is once turned off and the mode is switched to the "set value display" mode (step F4 in Fig. 8). In the "set value display" mode, the set value of various measurement or monitoring conditions (current upper / lower limit, peak value, effective value, etc.) used for resistance welding by "right turn operation" or "left turn operation" is repeated in the reverse order or in reverse order. Repeatedly displayed on the screen. Here, the "current upper limit value" is an upper limit setting value for the welding current, and when the welding current measurement value exceeds this upper limit setting value, the "HIGH" lamp of the current setting display unit 16 lights in the "measurement value display" mode. have. The "current lower limit value" is a lower limit setting value for the welding current, and when the welding current measurement value is smaller than this lower limit setting value, the "LOW" lamp of the current setting display section 16 is turned on in the "measurement value display" mode.

In addition, when "right turn operation" is performed while the item of "current lower limit value" is selected, or "left turn operation" is performed while the item of "current lower limit value" is selected, drawings are omitted, but in order. Sending or sending in reverse order is used to switch to the item of measurement or monitoring condition related to the energization time.

In the " measured value display " mode as described above, when the " two consecutive pressing operations " of the switch 14 is performed, the mode is switched to the "measured value display" mode (step F3 in Fig. 8).

As described above, in this embodiment, the switch 14 provided on the operation panel 10 can be rotated left and right, but can be pushed elastically, and the " right turn operation ", " left turn operation " Five types of switch operations are available: push operation, long press operation, and two consecutive press operation. That is, one switch 14 enables switch operation for five conventional switches. For this reason, the drastic miniaturization and simplification of the operation panel 10 are realized. From the user's point of view, the panel switch 14, which is easy to operate with a suitable size and shape, can be performed by only a rotary operation and a push operation, and thus, all of the desired panel operations can be performed.

In this embodiment, depending on the type of the lower mode identified and displayed on the display unit 12 on the operation panel 10, numerical input and item order are sent from the " right turn operation " or " left turn operation " Two types of input processing of sending are selectively performed in order, and two types of input processing of numerical confirmation input and item selection are selectively performed from " one push operation ". In this manner, it is also possible to perform various types of input processing under various types of modes by one type of switch operation.

The layout on the operation panel 10 in the above embodiment is one example, and various kinds of modifications are possible. For example, in each of the setting display units 16, 18, and 20, various item lamps may be arranged near the upper side, the lower side, or the left side of the numerical display unit or the alphanumeric display unit. It is also possible to configure all as LCD (liquid crystal display). In addition, the structure, shape, function, and the like of the switch 14 can be variously modified. For example, the ring member is configured to be rotatable from side to side, and a push button is provided inside the loop member, and the right and left rotation operations are performed by the loop member, and the push button is pressed. For example, as described above, the "single press operation", the "long press operation" and the "sequential press operation" may be performed. Alternatively, a switch other than a disk or annular member, for example, a lever-shaped member can be configured, and a switch operation (for example, a deflection in the XY direction, etc.) other than rotation or pressing can also be configured. .

In the above-described embodiment, the input processing contents for the " right turn operation " and " left turn operation " It is also possible to make a construction and to send or increment in the order of the items with respect to the "left turn operation". Similarly, the input processing for the "one press operation", the "long press operation" and the "two consecutive press operation" of the switch 14 can be changed as appropriate.

It is also possible to provide a switch separate from the switch 14 as described above on the operation panel 10.

As described above, according to the resistance welding measuring apparatus of the present invention, since it is possible to perform various types of switch operation and input processing with one switch, it is possible to realize miniaturization of the operation panel and improvement of operability at the same time.
