Description

  The present invention relates to a production line management apparatus, a production line management method, and a production line management program.

  In a product production line, an operator who arranges a product conveyed by a conveyor for each process may be manually assembled. In such a production line, the area and man-hour for one worker to perform work are determined in advance. And when an operator cannot complete a required work within a predetermined man-hour, the assembly of the product is prevented from being incomplete by stopping the production line. The work delay is determined by detecting the removal of parts and tools for each process with a sensor, and if the removal is not detected within a predetermined number of man-hours, it is determined that the work of the process is not completed and the production line Stop. Here, in this type of production line, for example, a work waiting time is provided in a part of the self-propelled conveyance line, and if a work delay occurs in any process, the production line is stopped by reducing the work waiting time. Is preventing.

  Furthermore, in order to reduce the frequency of stoppage of the production line, the work area and the support area are arranged in order along the direction of travel of the conveyor, and when work delay occurs in the work area, support work is performed in the support area There is something configured. If the worker fails to complete the predetermined work within the work area, the worker calls a supporter arranged outside the line, and the supporter supports the work to reduce the frequency at which the production line stops. It is like that.

The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
The foregoing general description and the following detailed description are exemplary and explanatory only and are not intended to limit the invention.

FIG. 1 shows a schematic configuration of a manufacturing apparatus including a line management apparatus.
The manufacturing apparatus 1 includes a manufacturing line 1A and a line management apparatus 4 (manufacturing line management apparatus) that manages the manufacturing line 1A. A conveyor apparatus 3 that conveys a product 2 to be manufactured is included in the manufacturing line 1A. In addition to being provided, a plurality of workers who perform work determined for each process and supporters who are mobilized at any time to eliminate work delays are arranged.

  In the conveyor device 3, a plurality of work carts 7 are connected in a line along the conveyance guide 8, and a driving force applying unit 9 is attached to the leading work cart 7 </ b> A. By moving the leading work cart 7A in the predetermined conveying direction indicated by the arrow AR1 at a constant speed by the driving force applying unit 9, all the remaining work carts 7 are moved in the same direction. One product 2 is placed on each work carriage 7. Furthermore, a plurality of processes are arranged along the movement path of the work cart 7, and the worker 2 arranged for each process performs the work determined for each process in order to manufacture the product 2.

  This manufacturing apparatus 1 has six steps, and each step is divided into a work area 10 and a support area 11 from the upstream side in the transport direction. The work area 10 is an area where the worker performs work determined for each process. Further, the work area 10 is divided into an A area 10A and a B area 10B in order from the upstream side in the transport direction. The two areas 10A and 10B are divided so that the progress of work can be confirmed. The support area 11 is an area where the supporter performs the remaining work in the process when the work is not completed in the work area 10. The conveyor device 3 is provided with a line ANDON 12 and a process ANDON 13 so that the operating state of the process can be informed to the surroundings. In addition, the number of the processes which the manufacturing apparatus 1 has is not limited to six, It can set arbitrarily. The work area 10 may not be divided into the two areas 10A and 10B.

  As shown in the enlarged schematic configuration of one process in FIG. 2, the parts storage 17 is arranged in each work area 10 and each support area 11 in parallel with the transport path of each work carriage 7 of the conveyor device 3. ing. In the parts place 17, parts 15 and tools 16 necessary for the work of the process are arranged. Furthermore, one detection device 18 and 19 for detecting the progress of work is provided in the area on the work cart 7 side of the parts storage 17. A transmission sensor is used for the detection devices 18 and 19. The transmission sensor detects the progress of work using the fact that light is blocked when the component 15 or the tool 16 moves. The detection device 18 is arranged mainly in a region where the component 15 is placed, and detects that the component 15 has been taken out from the component storage place 17. The detection device 19 is arranged mainly in a region where the tool 16 is placed, and detects that the tool 16 has been taken out from the component storage place 17. The detection devices 18 and 19 can use devices other than the transmission sensor, and the number of installations can be arbitrarily changed. For example, when a camera and an image processing device are used as the detection devices 18 and 19, the camera is installed above the component storage 17, and the image captured by the camera is processed by data processing to move the component 15 or the tool 16. Detect movement and detect work progress.

  A call button 20 (calling device) and an emergency stop button 21 are arranged at the rear end of the work area 10. The call button 20 is pressed when the worker cannot complete the predetermined work in the work area 10, and can call the supporter to perform the remaining work in the support area 11. The emergency stop button 21 is used when stopping the production line 1A.

  Here, the worker is a person who is regularly arranged on the production line 1A. Typically, one person is assigned to every process. The supporter is normally waiting in a waiting place (not shown) outside the conveyance path of the conveyor device 3, and when the call button 20 is turned on because support is required in any process, The work delay is eliminated by entering the support area 11 and performing the remaining work. A predetermined number of supporters are arranged according to the length of the production line 1A. The number of supporters is less than the number of processes.

  As shown in FIG. 3, the line management device 4 requests support from the drive control device 31 of the drive force application unit 9 of the conveyor device 3, the detection devices 18 and 19, the ANDONs 12 and 13, and a supporter. For example, it is configured to control the production line 1A by causing a computer to execute a management program 46. The notification device 32 includes, for example, a portable terminal carried by a supporter, a display device installed on the production line 1A so that a plurality of people can be confirmed, and the like.

  Here, the line management device 4 includes a control unit 41 having a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and the like, and further includes a communication device 42 that manages data communication, The data input device 43 and the output device 44, and a storage device 45 such as an HDD (Hard Disk Drive) are included. The storage device 45 stores a management program 46, line information 47, standard work information 48, and the like. The management program 46 is a program for executing various functions of the line management device 4. The line information 47 stores information related to the production line 1A such as the length of the production line 1A, the number of processes, and the moving speed of the conveyor device 3. In the standard work information 48, the work included in each process of the production line 1A, the order of the work for each process, and the standard work man-hour information of each work are stored so as to be searchable.

Further, the control unit 41 of the line management device 4 includes, as characteristic functions of this embodiment, a remaining work man-hour calculation unit 51, a support man-hour calculation unit 52, a work man-hour calculation unit 53, and a determination unit 54. The function can be divided into the notification unit 55.
The remaining work man-hour calculating unit 51 calculates the remaining work man-hours of the worker or the supporter for each process based on the outputs of the detection devices 18 and 19 and the standard work information 48.
The support man-hour calculating unit 52 calculates the support man-hours necessary for the supporter to finish the current support work and to solve the newly generated work delay based on the remaining work man-hours, the supporter's movement man-hours, and the like. .
The workable man-hour calculation unit 53 acquires the workmanship manpower of the supporter in the process in which the work delay has newly occurred based on the line information 47.
The determination unit 54 determines whether or not work delay has occurred. Furthermore, the required support man-hours are compared with the manufacturable man-hours to determine whether the production line 1A needs to be stopped.
For example, the notification unit 55 is configured to transmit information requesting support to the notification device 32 such as a portable terminal held by the supporter via the communication device 42. Moreover, you may comprise the notification part 55 so that information may be output to the display etc. which are displayed so that a supporter can confirm instead of transmitting information to the notification apparatus 32, or in addition to this.

Next, an example of each process performed in the production line 1A will be described with reference to FIG. In FIG. 4, processes are arranged on the horizontal axis, and operations for each process are arranged vertically.
Each process includes one or more operations. The number of operations can be different for each process. For example, in step 3, an A component assembly operation PS31, a B seal attachment operation PS32, a C component assembly operation PS33, and a D seal attachment operation PS34 are sequentially performed from the bottom. Furthermore, the standard work man-hour of the A part assembly work PS31 is a second, and the standard work man-hour of the B seal attaching work PS32 is b seconds. In addition, the standard work man-hour of the C component assembling work PS33 is c seconds, and the standard work man-hour of the D seal attaching work PS34 is d seconds. Further, the process 5 includes an E component assembly operation PS51, an F component assembly operation PS52, a G seal attachment operation PS53, and an H screw assembly operation PS54. Each operation is performed in order from the bottom, and the standard operation man-hours are e seconds, f seconds, g seconds, and h seconds, respectively.

  Note that the contents of work for each process schematically shown in FIG. 4, the order of work, and the standard work man-hour information are registered in advance as standard work information 48 in the storage device 45 of the line management device 4 shown in FIG. Has been.

Next, an operation management method in the production line 1A will be described mainly with reference to the flowcharts of FIGS. 2 to 4 and FIG. In the following, in order to facilitate understanding, a case where only one supporter is arranged on the production line 1A will be described as an example.
As shown in step S <b> 101, the determination unit 54 of the line management device 4 always monitors whether work delay has occurred. The work delay is determined by, for example, the detection unit 54 checking the man-hour progress from the timing when the work cart 7 is input to each process, and the parts 15 and the like from the detection devices 17 and 18 until the work man-hour determined for each work elapses. It is determined whether or not a signal indicating the unloading is output.

  If a work delay occurs in step S101, the process waits until the call button 20 is turned on in step S102. If the worker's work does not end in the work area 10, the worker presses the call button 20 to make a support request. As a result, the notification unit 55 of the line management device 4 outputs a support request signal including information identifying a process requiring support from the communication device 42 to the notification device 32, and requests support from the supporter.

  Here, when the supporter is in a standby state, that is, in a state where support work is not performed, the supporter checks the information received by the notification device 32 and enters the support area 11 of the process for which the support request has been made. Complete the remaining work. In this case, step S111 that proceeds from terminal S103 in FIG. 4 at terminal A is executed, and production is continued. In addition, if support is complete | finished if the information which shows the support end from the call button 20 or the notification apparatus 32 is input into the determination part 54 of the line management apparatus 4 when support work is complete | finished, whether a supporter is working. Can be easily determined. As another example, it may be determined that the support work is being performed based on the presence or absence of the remaining work man-hours in the support area 11 in the process in which the work delay has occurred first. For example, when the remaining work man-hour is zero, it is determined that the support work in the process in which the work delay has occurred first has been completed and the support work is not being performed. On the other hand, when the remaining work man-hour is not zero, it is determined that the support work in the process in which the work delay has occurred first still remains and the support work is being performed.

  On the other hand, when the supporter is performing the support work in another process at step S103, the processes after step S104 are executed. In step S104, the remaining work man-hour calculating unit 51 checks the worker's completed work with the detection devices 17 and 18 in the process in which the call button 20 is newly turned on. The completed work indicates which work is completed among a plurality of works in one process. For example, when the detection devices 18 and 19 detect the removal of the B seal in step 3 shown in FIG. 4, it is determined that the assembly work PS31 for the A part, which is the previous work, has been completed.

  In the subsequent step S105, the remaining work man-hour calculating unit 51 searches the standard work information 48 with information for specifying the process for which support is requested, and removes the completed work of the worker from all the work in the process. The remaining work of the process requested for support is extracted, and the standard work number of each work corresponding to the remaining work is totaled to calculate the remaining work number A of the process requested for support.

  Furthermore, in step S106, the remaining work man-hour calculation unit 51 detects the completion work of the supporter who is currently performing the support work by sensing the detection devices 17 and 18. Subsequently, in step S107, the remaining work man-hour calculation unit 51 searches the standard work information 48 using information for specifying the process during the support work, and removes the work completed by the worker and the supporter from all the work in the process. The remaining work that the supporter needs to work in that process is extracted and the standard work hours of each work corresponding to the remaining work are totaled to calculate the remaining work time B of the process being supported by the supporter To do.

  In step S108, the support man-hour calculation unit 52 calculates the support man-hours necessary for the supporter to finish the current support work and eliminate the newly generated work delay. Specifically, the support man-hour is [remaining work man-hour A of a process for which a new support request has been made] + [remaining work man-hour B of a process currently under support work] + [moving man-hour C between processes]. As the [remaining work man-hour A of the process for which a new support request has been made], the value calculated in step S105 is used. As the [remaining work man-hour B of the process currently being supported], the value calculated in step S107 is used. [Processing man-hour C between processes] is calculated from information on two processes, the number of processes on the manufacturing line 1A, the length of the manufacturing line 1A, and the like with reference to the line information 47. Information on the process during the support work may be specified by storing a history in ON / OFF of the call button 20 or may be specified by examining the output of the detection device 19 in the support area 11. Further, the movement man-hour C may be registered in the storage device 45 in advance.

  Next, in step S109, the workable man-hour calculating unit 53 refers to the line information 47, and the supporter performs support work in the support area 11 where the support is requested from the conveyor speed and the support area size (length). The workable man-hour D that can be performed is calculated. For example, when the conveyor speed is constant, the workable man-hour D becomes long in a process where the support area size is large. On the other hand, in the process where the support area size is small, the workable man-hour D is shortened.

  Thereafter, in step S110, the determination unit 54 determines whether the delayed work can be eliminated in the support area 11. Specifically, when the man-hour that can be worked is larger than the man-hour required for the supporter, that is, [work man-hour D]> [remaining work man-hour A of the process for which support is newly requested] + [currently supporting work If the remaining work man-hours B] + [moving man-hours C between processes], the supporter completes the current support work, moves to the process of the additional delayed work, and can eliminate the delayed work judge. In this case, the process proceeds to step S111, where it is determined that production is to be continued, and the processing from step S104 to step S112 is repeated until it is determined in step S112 that the work of the supporter has been completed. The completion of the work of the supporter is detected by the detection devices 18 and 19 of the process for which a new support request has been made. The determination unit 54 determines that the work of the supporter is completed when the detection devices 18 and 19 detect the completion of the last work of the corresponding process.

  On the other hand, in step S110, [workable man-hour D] ≦ [remaining man-hour A for the process for which support was newly requested] + [remaining man-hour B for the process currently being supported] + [transfer man-hour C between processes] ], The determination unit 54 determines that the supporter cannot eliminate the delayed work, and proceeds to step S113 to stop the production line 1A.

Next, a specific example of the flow for determining the completion of delayed work will be described with reference mainly to FIGS.
As shown in FIG. 6, when the work is not completed in the work area 10 in the process 3, the worker in the process 3 presses the call button 20, and the supporter enters the support area 11 in the process 3 and remains. Take over the work and execute it.
In this state, as shown in FIG. 7, a work delay occurs in step 5, and the worker turns on the call button 20. In this production line 1A, only one supporter is arranged, and the supporter performs the remaining work of the current process 3 and moves to the support area 11 of the process 5 for which a new support request has been made. The remaining work of the process 5 needs to be completed within a predetermined man-hour.

  For example, in the standard work information 48 shown in FIG. 8, when a work delay first occurs in the process 3, the worker in the process 3 has finished up to the second work PS32, but the third work PS33 and the fourth work PS33. It is assumed that the work PS34 cannot be completed and is a remaining work. It is assumed that the call button 20 is turned ON in step 5 when the supporter who has received a call in this state is working to finish the remaining work in the support area 11 of step 3.

When the supporter has finished up to the third work PS33 in step 3 when a new work delay occurs, the supporter's remaining work is only the fourth work PS34. From this, the remaining work man-hour B of the supporter in the process 3 is d seconds that is the work man-hour of the work PS34.
On the other hand, the completed work of the worker in step 5 in which work delay has newly occurred is work PS51 and work PS52, and the remaining work is work PS53 and work PS54. In this case, the remaining work man-hour A of the worker in step 5 is (e + f) seconds, which is the sum of the work man-hours of the work PS 53 and the work PS 54. The remaining work man-hour A is calculated from the remaining work man-hours in step 5 because the work man-hours that need to be supported due to work delays that occurred during the support work of the supporter.

  Furthermore, the movement man-hour C required for the supporter to move from the support area 11 in the process 3 to the support area 11 in the process 5 is set to c35 seconds. And the work man-hour which can work in the support area 11 of the process 5 without stopping the conveyor apparatus 3 shall be D second.

  From this, if D> e + f + c35 is established, the supporter can move to the support area 11 in the process 5 after completing the remaining work in the process 3, and can complete the remaining work in the process 5. 3 does not need to be stopped. On the other hand, if D ≦ e + f + c35, it is determined that the remaining work in step 5 cannot be completed unless the conveyor device 3 is stopped, and the production line 1A is stopped.

  As described above, in the manufacturing apparatus 1 having the line management apparatus 4, it is determined whether or not it is necessary to stop the manufacturing line 1 </ b> A by grasping the remaining work amount when the work delay occurs and the state of the supporter. Therefore, it is possible to reduce the line stop frequency compared to the case where the production line is stopped when the number of support requests is larger than the number of supporters. By reducing the line stop frequency, production efficiency can be improved.

  In addition, when two or more supporters are arranged in one production line 1A, the same determination process as described above is performed for each supporter, and work delay can be eliminated by any supporter. If it is determined that there is, production is continued. In this case, the line management device 4 is configured so that information for specifying a plurality of supporters is provided in advance, and a process of performing support work for each supporter can be instructed. In addition, the process for which a support request is first made and the process for which a support request is newly made may be the same process. The line management device 4 may include detection devices 18 and 19 and a call button.

Search the standard work information and search by the operation completed by the worker or the supporter, extract the uncompleted work of the worker or the supporter, add the work hours of the uncompleted work, and calculate the remaining work time Calculate and calculate the man-hours required for the product in the process where the work delay occurred to move to the next process as the man-hours that the supporter can work in the process where the work delay occurred, and the work delay occurred Previous The work can be calculated by calculating the support work time from the remaining work time in the process, the travel time for the supporter to move to the process where the work was delayed, and the supporter's remaining work time when the supporter is working. When the man-hour is equal to or less than the support man-hour, the production line is stopped, and when the work-capable man-hour is shorter than the support man-hour, the computer is caused to execute a process for continuing the production of the production line. Management program.
