Description

  The present invention particularly relates to a work management system that can efficiently record and manage a work of tightening a plurality of bolts and screws to a set torque value.

For field work such as bolting of equipment at the time of maintenance and inspection, after the operator tightens the bolt, the work team leader performs confirmation work to prevent forgetting bolt tightening or tightening failure.
However, in a plurality of bolt tightening operations, poor tightening and forgetful tightening are likely to occur, and it is difficult to completely prevent such an artificial mistake. Work management and education that relied on current people had limitations and were difficult to prevent.
Conventionally, a system disclosed in Patent Literatures 1 to 4 has been disclosed in order to eliminate such work defects.

The management system disclosed in Patent Literature 1 stores a master image obtained by causing an operator to perform a work process of a work in advance and capturing the work position of the work. Then, the worker performs work at the work position of the work object, and an image of the work position is taken each time the work is completed. If a master image that substantially matches the captured image is identified by comparing the captured image of the work position with the master image, and the work position can be identified for all the master images, it is determined that the work on the work object has been completed.
However, the work object may change due to the on-site environment, aging deterioration, scratches, and the like, and there is a possibility that a difference may occur when comparing the captured image and the master image during the subsequent work, making identification difficult. In addition, when the work object has a similar shape such as a plurality of bolts formed on a circular flange, it is difficult to distinguish from other bolts and identification is extremely difficult.

The management system disclosed in Patent Document 2 uses a torque wrench that activates the release mechanism when the set torque value for screw tightening is reached, and changes from the increasing tendency to the decreasing tendency of the tightening torque acting on the screw, for example. This is a system that manages the tightening state of a screw using the peak value as a tightening torque that actually acts on the screw.
However, when there are multiple screws in the object, it is not possible to determine whether the screw has already been tightened and whether the screw will be tightened from now on. Not considered. The identification code attached to the component is for calling the set torque of the object.

The management system disclosed in Patent Document 3 is based on output means for outputting work completion information indicating that work using a tool has been completed, side means for positioning a work position, work completion information, and work position information. And a processing means for specifying the work completion location, and the fact that the work to be performed has been completed can be grasped together with the position information.
However, the process and apparatus for positioning the work position are complicated, and the work may be complicated.

The management system disclosed in Patent Document 4 counts a tightening completion signal that is output when the bolt tightening torque exceeds a predetermined value, and whether the count value has reached a predetermined value or more that corresponds to the completion of all operations. Judgment is made.
However, when tightening a plurality of bolts, there is a possibility that the same bolts may be tightened because it is not determined whether the bolts have been tightened.

When the set value is input, the OK button (next button 241) is validated. If the input value does not match the target value and range, the OK button is not validated. When the OK button is pressed, the screen is switched to the working screen.

  As shown in FIG. 13B, the work in progress screen 242 displays items of work item 243, part number 244, supervision / work team head / worker 246, and a number field corresponding to the number of parts of the work target part. FIG. 249 (a schematic plan view of 12 tightening bolts attached to the flange as an example in this embodiment), a torque value 252, and an operator 250 are displayed. Thereby, the worker can always check the torque value set during the work.

Next, the bolt tightening operation is started (step 7). When the work start button 216 enabled on the login screen of the work terminal shown in FIG. 11A is pressed as the start time of the entire work, the work by the worker is started (step 100) and the work start time is recorded. Then, work time measurement is started (step 101).
The identification jig 80 is attached to the work object 12 in advance before the bolt tightening operation is started. The operator can select an arbitrary bolt from a plurality of bolts.

The operator temporarily tightens all the bolts of the work target component 14 using a torque wrench specified in the tightening operation, and then performs final tightening of any bolts.
When the screen is switched to the in-operation screen 242 shown in FIG. 13B, the bolt tightening start time is recorded (step 102). Then, the operator performs a tightening operation of tightening the bolt using a torque wrench. When the bolt tightening reaches the set value, the limit switch operates (step 103), the tightening is released, and a tightening completion signal that is a measured value of the torque value is transmitted to the control unit 28 of the work terminal 20. .

When the work completion signal is transmitted to the control unit 28, the box 248 of bolt number 1 on the screen of the work terminal 20 changes as colored. In addition, a selection mark (◯ mark) 254 is attached to a position that reaches bolt number 1 of the work object 12 illustrated in FIG. 249 on the screen, so that the tightening bolt in operation can be recognized.
The rework button 251 is pressed when the work is redone due to reasons such as being unable to continue the bolt work during the tightening work.

  FIGS. 14A and 14B are an explanatory diagram of (A) execution of tightening work and (B) explanatory drawing of completion of work on the working screen of the work terminal. The tightening completion signal is also transmitted to the tool control unit 44 of the work tool 40. When a work completion signal of the limit switch 42 is input, a control signal for starting the tool is transmitted from the tool control unit 44 to the identification code reading unit 46. The identification code reading unit 46 reads the identification code attached to each work target component. The position information of the read identification code is transmitted to the control unit 28 of the work terminal 20. The control unit 28 recognizes the bolt for which the tightening operation has been completed from the position information of the identification code (step 104), and the box 248 of the bolt number 1 changes as in other coloring.

  Next, a picture of the bolt that has been tightened is taken (step 105). The captured image is transmitted from the imaging terminal 30 to the image storage unit 26 of the work terminal 20. A determination is made as to whether or not this photography is within 4 seconds (step 106). If the photography is within 4 seconds from the reading of the identification code, it is determined that the photography of the bolt for which the tightening operation has been completed is completed (YES). On the other hand, if it is longer than 4 seconds, it is not determined that the photograph of the bolt that has been tightened is taken. In this case, the bolt tightening operation is performed again, and the process returns to the limit switch operation process (NO).

  As shown in FIG. 14A, a complete mark 257 indicating that the work is completed in the box 248 of the bolt number 1 when the photograph is taken and stored, and the work target part 14 in the drawing of the work target 12 When the completion mark 258 filled with the selection mark (◯ mark) is displayed, the bolt tightening end time is recorded (step 107). In addition, an icon 259 that can refer to the photographed image is attached near the completion mark 258 of the work target part for which the tightening work has been completed. Then, when performing the tightening work in the order of bolt numbers 1 to 12, the box 260 of the bolt number 2 to be worked next changes, such as coloring, on the work target part in the drawing of the work target A selection mark 261 (◯ mark) is added.

Then, the data storage management unit 29 of the work terminal 20 temporarily records the work data with a photo created by the control unit 28 (step 108). Thereafter, the number of tightening operations of the tightening bolt is counted by the operation number counter (step 109).
Next, the number of tightening bolts is determined. Specifically, the number of tightening bolts can be determined by taking the difference between the number of bolts of the work target part registered in advance (step 110) and the actual number of work performed (step 110). 111).

As a result of the determination, when the bolt tightening operation is performed, the operations from Step 103 to Step 109 are repeated for the bolt numbers 2 to 12.
As shown in FIG. 14B, when all the bolts are tightened, a complete mark 257 is displayed in the display column of all bolt numbers on the work screen, and all the work objects in the figure are displayed. A completion mark 258 is attached to the work target part. Then, a pop-up screen 262 indicating the completion of work is displayed. When the OK button 263 is pressed, the pop-up screen is closed. When the work end button 264 on the display screen is pressed, the screen is switched to the torque wrench setting screen 233 shown in FIG. When the tightening work by the worker is completed, the display of the worker 234 changes and it can be confirmed that the work is completed. When the tightening work is performed by the work team leader after the work of the worker is completed, the person in charge of the work team leader 235 of the worker registration shown in FIG. 13A is selected. The work team leader also performs the same tightening work as the worker.

When the tightening work by the work team leader is completed and the work end button 264 on the display screen shown in FIG. 14B is pressed, the work selection screen 223 shown in FIG. 11B is displayed. When the work completion button 265 on the work selection screen is pressed, the work time measurement is finished (step 112), the work finish time of the worker is recorded, and the work of the selected work item is finished (step 113).
When all the detailed work is finished and data is input, the work is finished (step 8).

FIG. 17 is an explanatory diagram of a work data management list table. The document creation unit 58 of the management terminal 50 creates a document such as a daily work report such as a work data management list based on the work data read from the work terminal 20. As an example, the work data management list table of the present embodiment displays a person in charge, work start time, work end time, torque wrench management number, torque value, and photo record for each work target part of the detailed work item. .
According to such a work management system of the present invention, it is possible to easily recognize a work target component being worked from a work target illustrated on the display screen. In addition, it is possible to easily record measurement values during work and images after work using the work terminal.
