First and second welding devices 1 and 2 are mutually connected via a network 3, respectively have a control device 10 for accepting information input by the operator and displaying information, a welding torch 41, a welding wire 42, a welding machine cart 44, a wire feeding device 45, a welding power supply 50, and weld a steel plate SP. The control device 10 has an input unit 11, a calculation unit 12 for calculating a welding condition of the welding device itself and outputting information to the other welding device, a storage unit 13 for storing data such as the welding condition and a program for function of the control device 10, a current-voltage power control unit 14 for controlling a wire feeding device 45 and a wire power supply 50, a driving instruction unit 15 for directing the drive of the cart 44.
Description
for example, the welding devices can automatically detect end portions of steel plates to be welded, and can stop an operation as the end of a welding operation when detecting the end portions. Therefore, when an operator starts the welding operation, the plurality of welding devices can automatically execute the welding operation to end the welding operation.
However, there is a case where a shape of a groove between the steel plates to be welded changes along with the welding operation. In that case, unless a welding condition such as a welding current and a welding voltage during the welding is changed in accordance with the shape of the groove, welding quality may be adversely affected. In addition, during the welding operation, for example, there exists an operation that the operator performs directly on the welding devices, such as removal of slag that is a non-metallic substance occurring in a welding portion and resupply of a flux that is a material used for removing oxides and the like occurring during the welding. Therefore, in a general welding operation, each operator is disposed for each welding device, and it has been necessary during the welding operation for the operator to monitor a welding state individually in the vicinity of the welding device and to perform operations such as setting change of the welding condition and the removal of slag as necessary. In addition, in a configuration of a conventional welding device, when a plurality of welding devices are operated simultaneously, the operator cannot set the welding condition of other welding device while checking a state of the other welding device from one welding device.
Therefore, a procedure of easily setting the welding condition of the other welding device even when the operator is under the welding operation in the one welding device will be described hereinafter. [Overall Description of Welding System]
Fig. 1 is a view showing a configuration example of a welding system according to the present embodiment.
The welding system has a first welding device 1 and a second welding device 2 connected to each other by a network 3 as an example of a communication line. As will be described below in detail, the first welding device 1 and the second welding device 2 are welding devices including the same components, and execute the welding operation by an automatic operation, based on information input by the operator. Although the first welding device 1 and the second welding device 2 include welding devices of various configurations, a one side welding device of submerged arc welding will be described as an example in the following description. In addition, the first welding device 1 and the second welding device 2 are assumed to communicate with each other via the network 3.
The network 3 is communication means used in information communication between the first welding device 1 and the second welding device, and is, for example, a LAN (Local
Area Network).
Description of Welding Device]
Next, configurations of the first welding device 1 and the second welding device 2 will be described. Fig. 2 is a perspective view of the first welding device 1 or the second welding device 2 (see Fig. 1) according to the present embodiment. In addition, Fig. 3 is a cross sectional view taken along line Y-Y in Fig. 2 in the first welding device 1 or the second welding device 2 according to the present embodiment. Since the first welding device and the second welding device 2 include the same configuration, the configuration of the first welding device 1 will be described hereinafter.
The first welding device 1 according to the present embodiment is a device which has a backing device 100 that disposes a backing flux on a back surface of a groove portion G formed with facing end surfaces of respective steel plates to be welded SP, and which covers a welding portion with a surface flux from a front surface and with the backing flux from a back surface and performs the welding by using welding wire 42.

Then, after the backing flux is disposed on the back surface of the groove portion G and the steel plates to be welded SP are fixed, the first welding device 1 uses the welding torch 41 to perform one side submerged arc welding from above the groove portion
G and welds the steel plates to be welded SP.
Hereinafter, the movement direction of the welding torch 41 (welding direction) may be referred to as the longitudinal direction, and the direction perpendicular to the movement direction of the welding torch may be referred to as the width direction.
In addition, the first welding device 1 includes a frame 20 that lift ably supports the backing device 100,

The main beams 21, the connecting beams 22, the parallel beams 23, and the vertical beams 24 are assembled in a concave shape when viewed from the longitudinal direction (when viewed in Fig. 3) so as to make it possible to dispose the backing device 100 inside.
In addition, as shown in Fig. 2, the frame 20 has a plurality of overhanging beams 25 overhanging outward in the width direction (opposite side to the side where the backing device 100 is disposed) from a site where the vertical beams 24 are disposed below the parallel beams 23. In addition, as shown in Fig. 2, the frame 20 has carts 26 disposed in lower portions of the connecting beams 22. The carts 26 can move on the rails R provided on the floor, and the backing device 100 moves in the width direction via the frame 20.
Next, the conveying and fixing device 30 will be described.
As shown in Figs. 2 and 3, the conveying and fixing device 30 is a device that moves the steel plates to be welded SP in the width direction above the backing device
100 and fixes the steel plates to be welded SP for the welding. The conveying and fixing device 30 includes a conveying roller 31 provided on each of the two parallel beams 23 of the frame 20, a magnet device 32 that fixes the steel plates to be welded SP by magnetism, and an auxiliary roller 33 that is disposed on each of the overhanging beams 25 and assists the conveying of the steel plates to be welded SP by the conveying roller 31.
Next, the welding machine 40 will be described.
As shown in Fig. 3, the welding machine 40 performs the welding from the front side of the groove portion G of the steel plates to be welded SP disposed above the backing device 100, and includes the welding torch 41, the welding wire 42 supplied to the welding torch 41, and a torch supporting member 43 that supports the welding torch 41 and is provided with rails 43a to be movable in the width direction. In addition, the welding machine 40 includes the welding machine cart 44 which travels along the welding machine beam B provided above the backing device 100 (see also Fig. 2) and to which the torch supporting member 43 is attached movably in the width direction.
Then, a bearing 44a is fixed to the welding machine cart 44, and the rails 43a provided in the torch supporting member 43 move via the fixed bearing 44a, whereby the torch supporting member 43 moves in the width direction and the welding torch 41 attached to the torch supporting member 43 moves in the width direction. The welding machine cart 44 includes a cart motor 44b, and a pinion 44c that is attached to a tip of a rotation shaft of the cart motor 44b and constitutes a rack and pinion mechanism together with a gear cut rack Bg on plate-like rails Br provided in an upper portion of the welding machine beam B. In addition, the welding machine cart 44 includes two wheels 44d that travel on the rails Br provided in the upper portion of the welding machine beam

The cart motor 44b is driven based on a welding speed signal that is a signal input from the control device 10to control a welding speed, and the wheels 44d travel on the rails Br provided in the upper portion of the welding machine beam B, whereby the welding machine cart 44 moves along the welding machine beam B. Thereby, the welding torch 41 supported by the welding machine cart 44 moves in the longitudinal direction.
In addition, the welding machine 40 includes a wire feeding device 45(see Fig. 4) that supplies the welding wire 42 to the welding torch 41.

DEVICE, AND CONTROL METHOD FOR WELDING DEVICE
The present invention relates to a welding device, a welding system, a program used in the welding device, and a control method for the welding device.
As a device for welding steel plates used in ships and the like, for example, there is proposed, as disclosed in Patent Document 1, a one side welding device that presses a backing flux from a back surface of a groove portion along the groove portion formed with facing end surfaces and performs welding from a front surface of the groove portion. The one side welding device described in Patent Document 1 includes a backing device having a first backing member and a second backing member that press the flux against the back surface of the groove portion formed with the butting end surfaces of the respective steel plates to be welded, conveying and fixing means that conveys the steel plates to be welded above the backing device to fix the steel plates, and a welding machine that performs the welding from the front surface of the groove portion. In addition, the one side welding device includes flux supply means that supplies the flux to the first backing member and the second backing member, and flux recovery means that recovers the flux from the first backing member and the second backing member.
In addition, Patent Document 2 discloses a robot control device in a machining system used in combination unit 11, the calculation unit 12, the current-voltage control unit 14, and the driving instruction unit 15 are realized. In addition, the storage unit 13 is realized by, for example, the ROM 10b. In addition, the input unit 11 is realized by, for example, the touch panel 10d.
The input unit 11 as an example of acceptance means and display means accepts the input operation of information on the welding operation by the operator.
Here, the input unit 11 includes a display screen used by the operator for the input operation, and examples of the input unit 11 can include well-known touch panels such as a capacitance type that detects a change in a surface charge of the panel forming a low voltage to electrically detect a position where the finger touches, and a resistance film type that electrically detects a contact position between the fingers of electrodes spaced apart from each other, as change in the position changing from a non-energized state to an energized state. Then, the input unit 11 accepts the input operation of information on the first welding device 1 as an example of first information by the operator, that is, the input operation of information such as a welding condition number defining a set value of the welding condition in the first welding device, a set value of the adjusted welding condition in the first welding device 1, and an instruction to start the welding in the first welding device 1. The input unit 11 outputs the information on the first welding device 1 to the calculation unit 12, based on the accepted input operation. In addition, the input unit 11 displays the set value of the welding condition in the first welding device 1 input by the operator on the display screen.
In addition, the input unit 11 accepts the input operation of information on the second welding device 2 as an example of second information by the operator, that is, the input operation of information such as a welding condition number in the second welding device 2, a set value of the adjusted welding condition in the second welding device 2, and an instruction to start the welding in the second welding device 2. The input unit 11 outputs the information on the second welding device 2 to the calculation unit 12, based on the accepted input operation. In addition, the input unit 11 displays the set value of the welding condition in the second welding device 2 input by the operator on the display screen.
Further, the input unit 11 acquires from the calculation unit 12 measured values of a welding current and welding voltage during the welding operation that are measured in the second welding device 2, and displays the acquired measured values of the welding current and the welding voltage on the display screen.
In addition, when the input operation by the operator of the welding conditions of the first welding device 1 and the second welding device 2 is performed in the second welding device 2, the input unit 11 acquires from the calculation unit 12the set value of the welding condition in the first welding device 1 input in the second welding device 2, the set value of the welding condition in the second welding device 2 input in the second welding device 2, and the measured values of the welding current and welding voltage measured in the second welding device 2. Then, the input unit 11 displays on the display screen the acquired set value of the welding condition in the first welding device 1, the acquired set value of the welding condition in the second welding device 2, and the acquired measured values of the welding current and welding voltage measured in the second welding device 2.
Although, here, the input unit 11 displays the measured values of the welding current and welding voltage measured in the second welding device 2 as the information indicating the current state of the second welding device 2, the input unit 11 is not limited thereto. For example, the input unit 11 may display images obtained by imaging an ammeter and a voltmeter included in the second welding device 2, an image obtained by imaging the shape of the groove between the steel plates to be welded in the second welding device 2, and the like.
The calculation unit 12 as an example of output means, acquisition means and transmission means calculates the welding condition in the first welding device 1, based on the information on the first welding device 1 input from the input unit 11. Here, when the welding condition number in the first welding device 1 is input from the input unit 11, the calculation unit 12 acquires the set value of the welding condition corresponding to the input welding condition number, from the storage unit 13. Then, the calculation unit 12 generates various signals necessary for controlling the welding machine cart 44, the wire feeding device 45, and the welding power supply 50, based on the set value of the welding condition acquired from the storage unit 13 and the set value of the adjusted welding condition acquired from the input unit 11.
The signal necessary for controlling the welding machine cart 44 means a signal for controlling a moving speed of the welding machine cart 44 (welding torch 41), that is, the welding speed signal indicating a welding speed command value. The signal necessary for controlling the wire feeding device 45 and the welding power supply 50 means the welding power supply control signal indicating the welding current command value and the welding voltage command value. The calculation unit 12 outputs the generated welding speed signal to the driving instruction unit 15, and outputs the generated welding power supply control signal to the current- voltage control unit 14. In addition, the calculation unit 12 outputs the set value of the welding condition in the first welding device 1 and the measured values of the welding current and welding voltage controlled by the current-voltage control unit 14, to the calculation unit 12 of the second welding device 2 (hereinafter, the calculation unit 12 of the second welding device 2 may be referred to as a calculation unit 12-2) in order to display on the input unit 11 of the second welding device 2.
In addition, the calculation unit 12 outputs the information on the second welding device 2 input from the input unit 11 to the calculation unit 12-2 via the network 3. Then, after the outputting, the calculation unit 12 acquires the measured values of the welding current and welding voltage measured in the second welding device 2, and outputs the acquired measured values to the input unit 11.
Further, the calculation unit 12 acquires the information on the first welding device 1 output by the calculation unit 12-2 via the network 3, and calculates the welding condition in the first welding device 1, based on the acquired information. Here, when the welding condition number in the first welding device 1 is input from the calculation unit 12-2, the calculation unit 12 acquires the set value of the welding condition corresponding to the input welding condition number, from the storage unit 13. Then, the calculation unit 12 generates and outputs the various signals necessary for controlling the welding machine cart 44, the wire feeding device 45 and the welding power supply 50, based on the set value of the welding condition acquired from the storage unit 13 and the set value of the adjusted welding condition acquired from the calculation unit 12-2. Then, the calculation unit 12 outputs the set value of the welding condition to the input unit 11, and also outputs the measured values of the welding current and welding voltage controlled by the current-voltage control unit 14 to the calculation unit 12-2.
It is to be noted that when the setting of the second welding device 2 is performed in the input unit 11 of the second welding device 2, the calculation unit 12 acquires the set value of the welding condition in the second welding device 2 and the measured values of the welding current and welding voltage measured in the second welding device 2 from the calculation unit 12-2 via the network 3. Then, the calculation unit 12 outputs the acquired set value and measured values in the second welding device 2 to the input unit 11.
The storage unit 13 stores data such as a map indicating correspondence between the welding condition number and the set value of the welding condition, the program for realizing the functions of the control device 10, and the like.
The current-voltage control unit 14 as an example of calculation means controls the wire feeding device 45 and the welding power supply 50, based on the welding power supply control signal input from the calculation unit 12.
Specifically, the current-voltage control unit 14 controls the wire feeding device 45 and the welding power supply 50 such that the welding current and the welding voltage between the steel plates to be welded SP and the welding wire 42 reach the welding current command value and the welding voltage command value of the welding power supply control signal. At that time, the current- voltage control unit 14 may perform feedback control, for example, based on the welding current and welding voltage output from the welding power supply 50. In addition, the current-voltage control unit 14 measures the welding current and the welding voltage to calculate the measured values, and outputs the calculated measured values of the welding current and the welding voltage to the calculation unit 12.
The driving instruction unit 15 controls the welding machine cart 44, based on the welding speed signal input from the calculation unit 12. Specifically, the driving instruction unit 15 controls the cart motor 44b such that the moving speed of the welding torch 41 (welding machine cart 44) reaches the welding speed calculated by the calculation unit 12. At that time, the driving instruction unit 15 may perform feedback control, for example, based on a rotation speed of the cart motor 44b detected by a rotary encoder attached to the cart motor 44b.
[Description of Display Screen]
Next, display screens included in the input unit 11 will be described. Figs. 5A and 5B are views showing examples of display screens included in the input unit 11 according to the present embodiment. Display of the input unit 11 is different between a display screen when the input operation of the information on the first welding device 1 is performed, as an example of a first screen, and a display screen when the input operation of information on the second welding device 2 is performed, as an example of a second screen. The respective display screens are shown in Figs. 5A and 5B. In addition, the first welding device 1 is assumed to perform the welding by using three welding torches 41, that is, three electrodes. In the same manner, the second welding device 2 is also assumed to perform the welding by using three electrodes.
Fig. 5A is a view showing an example of the display screen when the input operation of the information on the first welding device 1 is performed in the input unit 11 of the first welding device 1 before and during the automatic operation of the first welding device 1.
A wire remaining amount display unit 1101 displays a remaining amount of the welding wire 42 at each of the first to third electrodes in the first welding device 1.
A feeding amount of the welding wire 42 is counted in the wire feeding motor 45a, and when the remaining amount of the welding wire 42 falls below a threshold, the wire remaining amount display unit 1101 displays a warning. A welding current display unit 1102 displays the set value ! of the welding current at each electrode in the first welding device 1. A welding voltage display unit 1103 displays the set value of the welding voltage at each electrode in the first welding device 1. A welding speed display unit 1104 displays the set value of the welding speed of the welding machine cart 44 in the first welding device 1.
A condition number display unit 1105 displays the welding condition number set in the first welding device 1. The operator can change the number by touching the condition number display unit 1105 and inputting the welding condition number desired to be called. When the number is changed, the first welding device 1 is controlled under the changed welding condition corresponding to the changed welding condition number. A copying selection display unit 1106 includes a copying method selection button 1106a, and a copying method of a weld line in the first welding device 1 selected by the copying method selection button 1106a is displayed.
Here, the weld line means a place where the welding is performed, and corresponds to, for example, a site where two parts meet in order to couple the two parts. In addition, when the weld line is deviated from a predetermined position by the welding device, a method of correcting the deviation to return the weld line to the predetermined position is the copying method of the weld line. In the copying selection display unit 1106 shown in Fig. 5A, BEATUM copying performed with a device called
BEATUM is selected as the copying method.
A condition adjusting display unit 1107 includes an increase button 1107a and a decrease button 1107b, and the adjustment of the welding condition in the first welding device 1 is performed by pressing each of the buttons. For example, in the case of adjusting the welding current, the operator can increase the set value of the welding current in the first welding device 1 by first touching the welding current display unit 1102and successively pressing the increase button 1107a. In the same manner, the operator can adjust the set values of the welding voltage and the welding speed in the first welding device 1 by increasing and decreasing the set values.
A multi-operation button 1108 (an example of a switching portion) is pressed when the input operation of the information on the second welding device 2 is performed in the input unit 11 of the first welding device 1. In the case where the display of the input unit 11 of the first welding device 1 is the display screen shown in Fig. 5A, when the multi-operation button 1108 is pressed, the display of the input unit 11 is switched, and transitions from the display screen shown in Fig. 5A to the display screen shown in Fig. 5B.
Fig. 5B is a view showing an example of the display screen when the input operation of the information on the second welding device 2 is performed in the input unit 11 of the first welding device 1 before and during the automatic operation of the second welding device 2.
A unit display unit 1109 displays the unit of the welding device to be operated. The example shown in Fig. 5B is an example of the case where the input operation on the second welding device 2 is performed in the input unit 11 of the first welding device 1, and "Unit 2" ! representing the second welding device 2 is displayed on the unit display unit 1109.
A welding current display unit 1110 displays the welding current set value at each of the first to third electrodes in the second welding device 2and the measured value of the welding current by the ammeter in the second welding device 2. Here, in the case of setting the welding current, the operator is considered to set the welding current after checking the measured value of the current welding current and to adjust the set value while checking the measured value. However, since the operator can check the measured value of the welding current of the first welding device 1 by the ammeter (not shown) included in the first welding device 1, the measured value of the welding current in the first welding device 1 is not displayed on the welding current display unit 1102. On the other hand, since the operator cannot check the ammeter included in the second welding device 2 from the first welding device 1, the measured value of the welding current in the second welding device 2 is displayed on the welding current display unit 1110. In addition, as shown in Fig. 5B, the welding current display unit 1110 is assumed to display the measured value by a scale and pointer of the ammeter in accordance with display of the actual ammeter.
A welding voltage display unit 1111 displays the welding voltage set value at each electrode in the second welding device 2and the measured value of the welding voltage by the voltmeter in the second welding device 2.
Here, the measured value of the welding voltage in the first welding device 1 is not displayed on the welding voltage display unit 1103 in the same manner as the welding current display unit 1102; however the measured value of the welding voltage in the second welding device 2 is displayed on the welding voltage display unit 1111 in the same manner as the welding current display unit with a robot and a plurality of machine tools, and the robot control device includes a portable teach pendant for operating the robot control device and is connected to a plurality of machine tool control devices that controls the different machine tools respectively via communication means. The robot control device can operate the machine tool control devices through the machine tool screen of a display of the teach pendant.
Further, Patent Document 3discloses a welding robot control device wherein two or more robots are directly connected to one robot control device and programming pendants connected individually depending on operation contents are used to enable operation teaching of the individual robot and the operation teaching of the plurality of robots by one programming pendant, as necessary.

Patent Document 2: JP 4676544B
Patent Document 3: JP H9-179612 A
The welding devices can require change of welding conditions such as a welding current and a welding voltage in accordance with a state of steel plates to be welded and a shape of a groove portion formed with the steel plates concurrently with the welding operation.
Further, during the welding operation, for example, there exists an operation that an operator performs directly on
1110. In addition, as shown in Fig. 5B, the welding voltage display unit 1111 is assumed to display the measured value of the welding voltage by a scale and pointer of the voltmeter in accordance with display of the actual voltmeter. A welding speed display unit 1112 displays the set value of the welding speed of the welding machine cart 44 in the second welding device 2.
A condition number display unit 1113 displays the welding condition number set in the second welding device 2. In the same manner as the condition number display unit 1105, the operator can change the number by touching the condition number display unit 1113, and when the number is changed, the second welding device 2 is controlled under the changed welding condition corresponding to the changed welding condition number. A welding start display unit 1114 displays whether a pre- operation for starting the welding in the second welding device 2 is completed and the welding can be started.
When the welding can be started, the welding start display unit 1114 displays "Welding can be started,” and when the welding cannot be started, the welding start display unit 1114 displays "Welding cannot be started.”
In the case of starting the welding in the second welding device 2, a welding start button 1115 is pressed.
In the case of stopping the welding in the second welding device 2, a welding stop button 1116 is pressed. A condition adjusting display unit 1117 includes an increase button 1117a and a decrease button 1117b, and the adjustment of the welding condition in the second welding device 2 is performed by pressing each of the buttons in the same manner as the condition adjusting display unit 1107 of the first welding device 1. A return button 1118 is pressed in the case of returning to the display screen for performing the input operation on the first welding device 1. That is, in the case where the display of the input unit 11 of the first welding device 1 is the display screen shown in Fig. 5B, when the return button 1118 is pressed, the display of the input unit 11 transitions from the display screen shown in Fig. 5B to the display screen shown in Fig. 5A.
In addition, the copying selection display unit 1106 is displayed on the display screen shown in Fig. 5A, but is not displayed on the display screen shown in Fig. 5B.
Although in the copying selection display unit 1106, the copying method of the weld line is selected by the copying method selection button 1106a and the selected copying method is displayed, the selection of the copying method is an operation that the operator directly performs on the welding device as the pre-operation for starting the welding operation. That is, since the operator does not perform the selection of the copying method of the second welding device 2 from the input unit 11 of the first welding device 1, the display unit of the copying selection is not displayed on the display screen shown in Fig. 5B. Thus, on the display screen shown in
Fig. 5B, those relating to an operation that the operator directly performs in front of the welding device are not displayed, and those relating to an operation that the operator is likely to perform on the other welding device when being disposed for the one welding device are displayed.
As described above, the operator causes the display of the input unit 11 of the first welding device 1 to transition from the display screen for performing the input operation on the first welding device 1 to the display screen for performing the input operation on the second welding device 2, whereby the operator can perform the operation such as the setting change of the welding condition in the second welding device 2 from the first welding device 1. In addition, although in the examples shown in Figs. 5A and 5B, the display screens of the input unit 11 in the first welding device 1 are described, the same screens are also displayed in the input unit 11 of the second welding device 2. That is, on the input unit 11 of the second welding device 2, the screen shown in Fig. 5A is displayed as the screen for performing the input operation on the second welding device 2. Then, when the multi-operation button 1108 displayed on the input unit 11 of the second welding device 2 is pressed, the display of the input unit 11 of the second welding device 2 transitions from the display screen shown in Fig. 5A to the display screen shown in
Fig. 5B, and the operator can perform the operation such as the setting change of the welding condition in the first welding device 1 from the second welding device 2.
In addition, although in the display screens according to the present embodiment, the display screen shown in Fig. 5A and the display screen shown in Fig. 5B are switched and the input operation on the first welding device 1 and the input operation on the second welding device 2 are performed on the different display screens, the present embodiment is not limited thereto. For example, the input operation on the first welding device 1 and the input operation on the second welding device 2 may be performed on the same display screen. However, when the input operation on the first welding device 1 and the input operation on the second welding device 2 are performed on the same display screen, the operator is considered to perform an erroneous operation such as inputting the input item for the first welding device 1 into the second welding device 2. Therefore, when the input operation on the first welding device 1 and the input operation on the second welding device 2 are performed on the different display screens, the error of the operator can be suppressed. In addition, when the configuration of the display screen for the input operation on the second welding device 2 is largely different from the configuration of the display screen for the input operation on the first welding device 1, the operator is considered to have difficulty in the operation. Therefore, as shown in Figs. 5A and 5B, the display unit and the like on the display screen for the input operation on the second welding device 2 are disposed based on the disposition on the display screen for the input operation on the first welding device 1, whereby the operator can perform the input operation more easily. [Description of Setting Procedure of Welding condition]
Next, operations on the first welding device 1 and the second welding device 2 by the input unit 11 will be described. Figs. 6 and 7 are flowcharts showing setting procedures of the welding conditions of the first welding device 1 and the second welding device 2 by the input unit 11 of the first welding device 1. At first, the screen shown in Fig. 5A is assumed to be displayed as the display of the input unit 11.
First, the setting procedure of the welding condition of the first welding device 1 will be described. Fig. 6 is a flowchart showing the setting procedure of the welding condition of the first welding device 1 by the input unit 11 of the first welding device 1. The operator performs the setting of the welding condition from the display screen shown in Fig. 5A (step 101). For example, the operator touches the condition number display unit 1105 to input the welding condition number desired to be called. In addition, for example, the operator touches the welding voltage display unit 1103 and the increase button 1107a or the decrease button 1107b to adjust the welding voltage. Then, the information input into the input unit 11 is output to the calculation unit 12.
The calculation unit 12 generates various signals necessary for the control of the welding machine cart 44, the wire feeding device 45, and the welding power supply 50, based on the input information (step 102). Here, when the welding condition number is input, the calculation unit 12 acquires the set value of the welding condition of the first welding device 1 from the storage unit 13, and generates various signals necessary for the control of the welding machine cart 44, the wire feeding device 45, and the welding power supply 50, based on the acquired set value of the welding condition. In addition, when the information input into the calculation unit 12 is the set values of the adjusted welding current and welding voltage, the calculation unit 12 generates various signals based on the set values.
Next, the calculation unit 12 outputs the generated welding speed signal to the driving instruction unit 15, and outputs the generated welding power supply control signal to the current-voltage control unit 14. Then,
based on the welding speed signal and the welding power supply control signal, each of the welding machine cart 44, the welding power supply 50, and the wire feeding device 45 is controlled (step 103). In addition, the calculation unit 12 outputs the set value of the welding condition and the measured values of the welding current and welding voltage measured by the current-voltage control unit 14 to the second welding device 2 (step 104). Thereby, when the screen shown in Fig. 5B is displayed in the second welding device 2, the measured values of the welding current and the welding voltage in the first welding device 1 are displayed together with the set value of the welding condition in the first welding device 1.
Next, the setting procedure of the welding condition of the second welding device 2 will be described. Fig. 7 is a flowchart showing the setting procedure of the welding condition of the second welding device 2 by the input unit 11 of the first welding device 1. First, the operator presses the multi-operation button 1108, and causes the display of the input unit 11 to transition from the display screen shown in Fig. 5A to the display screen shown in Fig. 5B (step 201). Then, the operator performs the setting of the welding condition from the display screen shown in Fig. 5A (step 202). Since the setting procedure is the same as that in step 101, the description thereof will be omitted. Then, the information input into the input unit 11 is output to the calculation unit 12, and further, the information input into the calculation unit 12 is output to the calculation unit 12-2 of the second welding device 2 (step 203). In the second welding device 2, the setting of the welding condition is performed based on the input information.
Here, since the processing in steps 204 and 205 is the same as the processing in steps 102 and 103, the description thereof will be omitted.
Next, the calculation unit 12-2 of the second welding device 2 outputs the measured values of the welding current and welding voltage measured by the current-voltage control unit 14 of the second welding device 2 to the first welding device 1 (step 206).
Thereby, the measured value of the welding current of the second welding device 2 can be displayed on the welding current display unit 1110 in the first welding device 1.
In addition, the measured value of the welding voltage of the second welding device 2 can be displayed on the welding voltage display unit 1111.
As described above, in the welding system according to the present embodiment, the operator can perform the input operation on the second welding device 2 in addition to the input operation on the first welding device 1, by using the input unit 11 of the first welding device 1. In the same manner, the operator can perform the input operation on the first welding device lfrom the second welding device 2. Therefore, the operator can monitor the state of the second welding device 2 and the shape of the groove between the steel plates to be welded
SP to perform the operation such as the setting of the welding condition of the second welding device 2, while operating the first welding device 1.
In addition, in the input unit 11 of the first welding device 1, the set value of the welding condition in the second welding device 2 and the measured values in the second welding device 2 can be displayed in addition to the set value of welding condition in the first welding device 1. In the same manner, also in the second welding device 2, the set value of the welding condition in the first welding device 1 and the measured values in the first welding device 1 can be displayed in addition to the set value of the welding condition in the second welding device 2. Therefore, for example, when setting the welding condition of the second welding device 2 from the input unit 11 of the first welding device 1, the operator can perform the setting while checking the set value of the welding condition in the second welding device 2 and the measured values in the second welding device 2 by the display screen, and perform the setting of the welding condition in the second welding device 2 easily.
That is, in the conventional welding device, when a plurality of welding devices is operated simultaneously, there has been a case where each operator performs the welding operation on each welding device; however in the welding system of the present embodiment, one operator can perform the operation on the other welding device from the one welding device. Therefore, it is possible to reduce the number of operators in the welding operation.
In addition, the welding system according to the present embodiment can be realized by such a simple configuration that the first welding device 1 and the second welding device 2 are connected by the network 3.
Further, since the operator can perform the operations mutually on the first welding device 1 and the second welding device 2, even when it is necessary to perform the input operations on both the welding devices, the operator only needs to be disposed for any one of the welding device 1 and the second welding device 2. [Other Configuration Examples of the Present Embodiment]
Although in the present embodiment, the welding system is configured to include two welding devices of the first welding device 1 and the second welding device 2, the welding system is not limited to this configuration. That is, the welding system may be configured to include three or more welding devices connected to the network 3 such that the operator can perform the operation such as the setting change of the welding conditions in other welding devices from one welding device. As an example of this configuration, when two welding devices (hereinafter, referred to as
Unit 3 and Unit 4) are connected to the network 3 in addition to the first welding device 1 (hereinafter, referred to as Unit 1) and the second welding device 2 (hereinafter, referred to as Unit 2), the operator can perform the input operations on Units 2 to 4 from Unit 1.
In the same manner, the operator can perform the input operations on Units 1, 3, and 4 from Unit 2, the input operations on Units 1, 2, and 4 from Unit 3, and the input operations on Units 1 to 3 from Unit 4.
Fig. 8 is a view showing an example of a display screen when the input operations on the other welding devices are performed from the first welding device 1 according to the present embodiment. Here, as described above, four welding devices of Units 1 to 4 are assumed to be connected to the network 3. When the multi- operation button 1108 of the display screen shown in Fig. 5A is pressed in the input unit 11 of Unit 1,, the display of the input unit 11 transitions from the display screen shown in Fig. 5A to the display screen shown in
Fig. 8. In the case of setting the welding condition of
Unit 2 from Unit 1, the operator only needs to press a unit 2 button 1119p. When the unit 2 button 1119 is pressed, the display of the input unit 11 transitions from the display screen shown in Fig. 8 to the display screen shown in Fig. 5B. Then, "Unit 2" is displayed on the unit display unit 1109.
In the same manner, in the case of performing the input operation on Unit 3 from Unit 1, when the operator presses a unit 3 button 1119c, the display of the input unit 11 transitions to the display screen shown in Fig. 5B, and "Unit 3" is displayed on the unit display unit 1109. In addition, in the case of performing the input operation on Unit 4 from Unit 1, when the operator presses a unit 4 button 1119d, the display of the input unit 11 transitions to the display screen shown in Fig. 5B, and "Unit 4" is displayed on the unit display unit 1109. In addition, when the operator presses a unit 1 button 1119a, the display of the input unit 11 transitions from the display screen shown in Fig. 8 to the display screen shown in Fig. 5A.
As described above, the operator can perform the input operations on the other welding devices from the one welding device by selecting the other welding device desired to be operated. That is, the operator can set the welding conditions in other welding devices from the one welding device, and the one welding device can display the set values of the welding conditions, the measured values, and the like in the other welding devices. Therefore, the operator can perform the input operations on a plurality of welding devices from one the welding device, such as removal of slag and supply of a flux. Therefore, in a general welding operation, each operator is disposed for each welding device, and it has been necessary during the welding operation for the operator to monitor a welding state individually in the vicinity of the welding device and to perform operations such as setting change of the welding condition and the removal of slag as necessary.
The technique disclosed in patent document 2, a robot control device operates a plurality of machine tools. Further, the welding robot control device disclosed in Patent Document 3, teaching on a plurality of robots is executed by a program pendent. However, according to these conventional arts, setting of welding condition with confirming the state of the device for setting the welding condition cannot be implemented and operation with checking a state of the other welding device cannot be implemented.
An object of the present invention is that when an operator is under welding operation in one welding device, a welding condition of the other welding device is easily set.
In order to achieve the object a welding device to which the present invention is applied is connected to other welding device via a communication line and comprises an acceptance unit that accepts an input operation of first information on a welding condition during welding to be set in the welding device itself by an operator, and an input operation of second information on a welding condition to be set in the other welding welding device, and it is possible to reduce the number of the operators compared to the case where each operator performs the welding operation on each welding device.
In addition, although the input unit 11 is a touch panel in the present embodiment, the input unit 11 is not limited to this configuration. For example, the input unit 11 may be configured to include an input button for the operator to perform the input operation, separately from the display screen.
