  However, the estimated work time and the work time in the actual production line do not always match. For this reason, in an actual production line, the work load at each work station becomes unbalanced, and the stop time caused by a specific work station may be longer than the stop time caused by another work station. In such a case, it is necessary to perform the line work in accordance with a specific work station having a long stop time, resulting in a long production time. For this reason, it is necessary to review the work distribution so that the work load at each work station is balanced.

  Accordingly, an object of the present invention is to support review of work distribution for a plurality of work stations included in a production line.

  The line work management support system according to the embodiment will be described below. FIG. 1 is a schematic diagram showing the overall configuration of the production line 10 and the line work management support system 30.

  The production line 10 will be described. The production line 10 uses a wire harness incorporated in an automobile as a production target. A wire harness is a part that bundles a plurality of electric wires and the like while appropriately branching according to the form of wiring to the automobile, and is a component that connects various electrical components mounted on the automobile in a state of being incorporated in the automobile. Used as

  The production line 10 has a plurality of (eight here) work stations ST1 to ST8 provided along a predetermined line. Each work station ST1-ST8 is a place where the worker who produces a wire harness performs the assigned work. Here, the work stations ST1 to ST8 are provided with an interval along an oval line. However, the work stations ST1 to ST8 may be provided along a straight line or a circular line.

  The production line 10 is provided with a transport device 20 for transporting the wire harness. The transport device 20 includes a plurality of work carts 22 provided at intervals along the predetermined line, and a traveling mechanism unit 24 that causes the plurality of work tables to travel along the predetermined line. Yes. The work cart 22 is a work table for producing a wire harness, and is configured to be able to travel along the predetermined line by wheels or the like provided at the bottom.

  The traveling mechanism unit 24 is configured to drive the plurality of work carts 22 along the predetermined line. Here, the traveling mechanism unit 24 is provided with driving wheels 25a and driven wheels 25b at both ends along the long axis direction of the oval line provided with the work stations ST1 to ST8, and these driving wheels 25a. The endless annular drive belt 26 is wound around the driven wheel 25b. Each work carriage 22 is connected to the drive belt 26 with a gap. Then, under the control of the traveling control unit 28, when the traveling motor 27 is rotationally driven to rotate the driving wheel 25a, the driving belt 26 is circulated and rotated, and the plurality of work carts 22 travel in synchronization. As a result, the plurality of work carts 22 and the wire harnesses being produced on the work carts 22 are conveyed so as to sequentially pass through the work stations ST1 to ST8.

  But the structure which makes the work trolley 22 drive is not restricted to the said example, The structure which the work trolley 22 itself self-propels may be sufficient. In addition, it is not essential that the production object is transported on the work carriage 22. For example, the production object may be transported by a belt conveyor or the like.

  Each of the plurality of work stations ST1 to ST8 is provided with a work stop instruction panel 29. The work stop instruction panel 29 has a work stop instruction switch 29a and a work stop release instruction switch 29b, and is configured to accept an operator's work stop instruction and work stop release instruction at each of the work stations ST1 to ST8. ing. Then, a work stop instruction and a work stop release instruction received by each work stop instruction panel 29 are given to the travel control unit 28. The travel control unit 28 stops the rotational drive of the travel motor 27 when a work stop instruction is given through any of the work stop instruction panels 29 while the travel motor 27 is rotationally driven. When a work stop cancellation instruction is given through 29, the rotational drive of the traveling motor 27 is resumed.

  Thus, when a work stop instruction is given at any of the work stations ST1 to ST8 during the line work in a state where the plurality of work carriages 22 are traveling, the plurality of work carriages 22 are stopped in synchronization and the wire harness The transportation is stopped. After that, when a work stop cancellation instruction is given, the plurality of work carts 22 resumes traveling in synchronism and the conveyance of the wire harness is resumed.

  This line work management support system 30 is incorporated in the production line 10 as described above and supports the work management, and includes a plurality of work stop state output units 32 and a line work management device 50. Yes.

  The plurality of work stop state output units 32 are provided corresponding to each of the plurality of work stations ST1 to ST8, and can identify the work stations ST1 to ST8 to which the work stop instruction or the work stop release instruction is given. Thus, the work stop instruction or the work stop release instruction to the corresponding work stations ST1 to ST8 can be output.

  Here, the work stop state output unit 32 is configured to be able to accept input of signals corresponding to the work stop instruction and the work stop release instruction in the corresponding work stop instruction panel 29 via an input circuit or the like. The wireless terminal device is capable of wirelessly transmitting data corresponding to the instruction content together with its own identification ID. The identification ID of the work stop state output unit 32 is used as information for identifying the work stations ST1 to ST8 in the line work management apparatus 50.

  However, the work stop state output unit 32 does not have to be a wireless terminal device, and may be connected to the line work management device 50 in a wired format such as a wired LAN.

  In addition, the line work management support system 30 includes a travel state detection unit 36 that detects the travel state of the plurality of work carts 22. Here, as shown in FIGS. 1 and 2, the traveling state detection unit 36 includes a reflective optical sensor having a light projecting unit and a light receiving unit, and is directed toward the work carriage 22 on which the detected light travels. Is set to be projected. Further, a reflection member 23 such as a reflective tape that reflects detection light is attached to the work carriage 22, and when the reflection member 23 portion of the work carriage 22 travels in front of the traveling state detection unit 36, the detection light is reflected. Reflected by the member 23, the reflected light is received by the traveling state detection unit 36. And the detection signal of the reflected light in the driving | running | working state detection part 36 is given to the line work management apparatus 50. FIG. On the line work management device 50 side, it is possible to determine whether the plurality of work carriages 22 are traveling or stopped based on the intermittent state of the detected light, and the number of work carriages 22 that have passed in front of the traveling state detection unit 36 is determined. You can also count. Based on the detection signal, the line work management device 50 determines the traveling speed of the work cart 22 (the time required for each work cart to pass a fixed point, the time required for a predetermined number of work carts to pass a fixed point, etc.), Counts the number of passing fixed points of the work cart 22, and thereby the time required to produce a predetermined number of wire harnesses (also called cycle time), grasps the number actually produced, the degree of production progress, and the prediction of production completion Time can be managed. Such a traveling state detection unit 36 can be easily incorporated into the existing production line 10, and thus has an advantage that it is possible to easily manage the transportation state for the existing equipment.

  FIG. 3 is a block diagram showing the line work management device 50. The line work management device 50 has a function as a work content receiving unit that accepts work content that causes work to be stopped, and can execute functions as a management data generation unit 52a and a distribution data generation unit 52b. Has been.

  More specifically, the line work management device 50 includes a CPU 52, a main storage unit 53, an auxiliary storage unit 54, an input / output circuit unit 55, an input unit 56, a display unit 57, and the like interconnected via the bus line 51. It is composed of a general computer. The main storage unit 53 is configured by a RAM (Random Access Memory) or the like, and is provided as a work area when the CPU 52 performs a predetermined process. The auxiliary storage unit 54 is configured by a non-temporary non-volatile storage device such as a flash memory or a hard disk device, and stores a management data generation program 54a and a distribution data generation program 54b in addition to a basic program. Yes. Then, in accordance with the procedure described in the management data generation program 54a, the CPU 52 as the main control unit executes arithmetic processing, and the outputs from the plurality of work stop state output units 32 and the work content receiving unit are accepted. As a management data generation unit 52a that generates work distribution review data 54c in which a work factor that causes a work stop and a stop time are associated with each of the plurality of work stations ST1 to ST8 based on the work content. The function is realized. Further, the CPU 52 as the main control unit executes arithmetic processing according to the procedure described in the distribution data generation program 54b, thereby generating time distribution data 54d and work distribution data 54e based on the work distribution review data 54c. The function as the distribution data generation unit 52b is realized. Note that the work distribution review data 54c, which is the processing result of the management data generation unit 52a, the time distribution data 54d and the work distribution data 54e, which are processing targets or processing results of the distribution data generation unit 52b, are also included in the auxiliary storage unit. 54. However, some or all of the functions performed by the management data generation unit 52a and the distribution data generation unit 52b may be realized by hardware using a dedicated logic circuit or the like.

  In the line work management apparatus 50, the input / output circuit unit 55, the input unit 56, the display unit 57, and the like are also connected to the bus line 51.

  The input / output circuit unit 55 is an interface for input / output signals for transmitting / receiving data to / from the outside. Here, the radio communication device 60 is connected to the input / output circuit unit 55. The wireless communication device 60 performs wireless communication with each work stop state output unit 32, and specifies the work stop instruction, the work stop release instruction, and the work stations ST1 to ST8 transmitted from each work stop state output unit 32. Information (identification ID) is given to the line work management device 50 through the input / output circuit unit 55.

  The input unit 56 includes various switch devices such as a keyboard, a pointer such as a mouse, a touch panel, and the like. The display unit 57 is configured by a liquid crystal display device or the like, and under the control of the CPU 52, a candidate list of work stop factors, various information based on the work distribution review data, various information based on the distributed data, the traveling state detection unit 36 Various information obtained based on the detection signal is displayed.

  The input unit 56 has a function as a work content receiving unit that receives the work content that causes the work to stop. The work content can be received as follows, for example. In other words, as shown in FIG. 4, a candidate list of work stop factors is displayed on the display unit 57. Here, the candidates included in the candidate list are partial operations for producing a wire harness, and include, for example, a work target and work contents for the work target. The work target is, for example, part specification information (temporary connection No. 1, part A No. 1, etc.) or position specification information in the wire harness (branch No. 1, etc.). Moreover, the work content with respect to the said work object is the actual work content (wiring, tape winding, attachment) which an operator performs, for example. This work content is a work unit when work is distributed to each work station ST1 to ST8, and is registered in advance as a candidate list. Then, when the worker selects one of the candidate lists of work stop factors from the input unit 56, the work content that causes the work stop is accepted. Here, an operator who performs maintenance management of the entire production line 10 is assumed as an operator who inputs the work content that causes the work stoppage through the input unit 56.

  However, the work content receiving unit is not limited to the above configuration, and may be configured to directly input the work content that caused the work stoppage using characters, symbols, or the like, or the work content that caused the work stoppage cause A configuration may be adopted in which an identifier printed in association with is read and input by a scanner or the like. Moreover, even if the work content reception unit is provided corresponding to each work station ST1 to ST8, the worker at each work station ST1 to ST8 individually inputs the work content that caused the work stoppage. Good.

  FIG. 5 is a flowchart showing processing by the management data generation unit 52a, and FIG. 6 is a diagram showing an example of first work distribution review data generated by the management data generation unit 52a. Here, the first work distribution review data is generated, for example, as data in which a stop number is associated with a stop time, a stop time, a stop station, and a stop factor. The stop number is, for example, a number given in a time-series order according to the time when the stop occurs. The stop time includes a stop start time and a stop start end time at which the stop start ends, and the stop time is a time between the stop start time and the stop start end time. The stop station is specific information of the work stations ST1 to ST8 to which the work stop instruction is input, and the stop factor is the work content that is the work stop factor input through the work content receiving unit.

  First, as shown in step S1, it is determined whether or not line work has been started. This determination is made by receiving an input of a direct line work start instruction to the line work management apparatus 50 or the like. If it is determined in step S1 that the line work has not started yet, the process of step S1 is repeated. If it is determined that the line work has started, the process proceeds to step S2.

  In step S2, the presence / absence of a work stop instruction at any of the work stations ST1 to ST8 is determined based on the transmission information from each work stop state output unit 32. If it is determined that there is no work stop instruction, the process of step S2 is repeated. If it is determined that there is a work stop instruction in any of the work stations ST1 to ST8, the process proceeds to step S3.

  In step S3, one of the stop numbers is assigned to the current stop, and the stop start time and the work station number are registered for the stop number. The stop start time is a time corresponding to an actual work stop instruction by the worker. When the stop instruction is received by the work stop state output unit 32, a stop instruction is issued from the work stop state output unit 32 to the wireless communication device 60. It is the time when the signal including it is transmitted, or the time when the stop instruction is recognized in the line work management device 50. The work station number is specific information of a work station corresponding to the work stop state output unit 32 to which the work stop instruction is transmitted, and here, any one of ST1 to ST8 is registered. After step S3 ends, the process proceeds to step S4.

  In step S4, it is determined whether or not a stop factor is registered. If it is determined that no stop factor is registered, step S4 is repeated. If it is determined that a stop factor is registered, the process proceeds to step S5.

  In step S5, a stop factor is registered for the stop number, and then the process proceeds to step S6.

  In step S6, it is determined whether or not the line work is finished. This determination is made by receiving an input of a direct line work end instruction to the line work management apparatus 50 or the like. If it is determined in step S6 that the line work has not been completed, the process returns to step S2 and the processes in and after step S2 are repeated. On the other hand, if it is determined that the line work is completed, the process proceeds to step S7. At this stage, first work distribution review data in an arbitrary production number unit or an arbitrary time unit is generated.

  In step S7, it is determined whether or not there is an instruction to generate data for each work station as the second work distribution review data. If it is determined in step S7 that there is no generation instruction, the processing in step S7 is repeated, and if it is determined that there is a generation instruction, the process proceeds to step S8.

  In step S8, data for each work station is generated based on the first work distribution review data. The data for each work station eliminates the distinction regarding the stop number and stop time in the first work distribution review data, and, as shown in FIG. 7, the total stop time and the cause of work stop for each of work stations ST1 to ST8. It is data that associates with the work that became. In the example shown in FIG. 7, the actual work time for each work station ST1 to ST8 at the time of the predetermined number production is shown. It is assumed that the ideal work time without work delay is 200 seconds, and the work stations ST2 and ST5 indicate that there is no work delay and the work is completed within the ideal work time. In addition, in the work stations ST1, ST3, ST4, ST6, ST7, and ST8, the ideal work time exceeds 200 seconds, indicating that work delay has occurred. Further, the portion of the rod-like portion that exceeds 200 seconds is divided into one or a plurality, and each divided region is associated with the work that caused the work stoppage. This association may be associated as data and referred to according to the operator's operation or the like. As a result, for each work station ST1 to ST8, it is possible to grasp the total work stop time and the content and ratio of the work that caused the work stop in the total work stop time. However, in this case, the data for each work station as the second work distribution review data as shown in FIG. 7 is generated from the first work distribution review data as shown in FIG. The data for each work station may be directly generated based on the transmission information from the status output unit 32 and the work content that causes the work stop accepted through the input unit 56.

  The distribution data generation unit 52b has a function of generating time distribution data 54d and a function of generating work distribution data 54e based on the work distribution review data.

  FIG. 8 is a flowchart showing a process in which the distribution data generating unit 52b generates the time distribution data 54d, and FIG. 9 is a diagram showing an example of the generated time distribution data 54d.

  That is, after the first or second work distribution review data is obtained, the presence / absence of a creation instruction for the time distribution data 54d is determined in step S11. If it is determined that there is a creation instruction, the process proceeds to step S12.

  In step S12, based on the first or second work distribution review data, the total stop time (total stop time) in all the work stations ST1 to ST8 is calculated, and then the process proceeds to step S13.

  In step S13, the total stop time is distributed to the work stations ST1 to ST8. The distribution is performed, for example, by equally distributing the total stop time by dividing the total stop time by the number of work stations ST1 to ST8. Then, the processing is terminated by displaying the distribution result on the display unit 57 or the like.

  The distribution result is displayed, for example, as shown in FIG. In the example shown in FIG. 9, the total stop time of the work stations ST1 to ST8 is approximately 260 seconds, and when this is divided by the number of work stations ST1 to ST8, it is approximately 32.5 seconds. Therefore, a time allocation guide line La as a distribution result is displayed at a position obtained by adding 32.5 seconds to the ideal work time of 200 seconds.

  Then, an operator or the like who performs maintenance management of the entire production line 10 sees the above distribution result and transfers the work contents of the work stations (for example, ST1, ST3, ST4) that have been overworked to other work stations ( For example, the work distribution in each of the work stations ST1 to ST8 can be appropriately reviewed so as to be redistributed to ST2, ST5, and the like.

  FIG. 10 is a flowchart showing a process in which the distribution data generation unit 52b generates the work distribution data 54e.

  That is, after the first or second work distribution review data is obtained, in step S21, it is determined whether or not there is a creation instruction for the work distribution data 54e.

  In step S22, based on the first or second work distribution review data, the work content that has become a stop factor in each of the work stations ST1 to ST8 is specified, and the process proceeds to the next step S22.

  In the next step S22, at least one of the work contents that caused the stoppage in each of the work stations ST1 to ST8 is redistributed to the other work stations ST1 to ST8.

  FIG. 11 conceptually shows an example of the reallocation process. In this example, a state is shown in which the work content that has become a stop factor at each work station ST1 to ST8 is distributed to work stations ST1 to ST8 on the downstream side (here, one downstream side). That is, the stop factor work of the work station ST1 is distributed to the downstream work station ST2, the stop factor work of the work station ST3 is distributed to the downstream work station ST4, and the stop factor work of the work station ST4 is assigned to the downstream work. Allotted to station ST5, and so on. The most downstream work station ST8 and the most upstream work station ST1 are handled in a cyclic manner so that the stop factor work of the most downstream work station ST8 is distributed to the most upstream work station ST1. Yes.

  Normally, the work stop instruction is issued immediately before the work ends at the work stations ST1 to ST8, so the stop factor work is a work close to the final stage of the work assigned to the work stations ST1 to ST8. For this reason, even if the stop factor work is redistributed to one downstream side, it is normally considered that no problem occurs in the order of work. However, it is not necessary to redistribute all the work contents that have caused the stoppage at each work station ST1 to ST8 to the downstream side, referring to the data of the work distribution originally planned and the like at each work station ST1 to ST8. You may make it redistribute the operation | work of back order downstream.

  If this redistribution process is repeated, it is considered that each work that causes a stop is eventually processed within a predetermined work time at any of the work stations ST1 to ST8. For this reason, it is considered that the work distribution has converged so that the work load at each work station is eventually balanced.

  The process shown in FIG. 11 is a process of allocating the work content that has caused the conveyance stop at each work station ST1 to ST8 to the downstream side. Can be redistributed to.

  FIG. 12 conceptually shows another example of the reallocation process. This example shows an example in which the work content that has become a stop factor in each work station ST1 to ST8 is distributed to the other work stations ST1 to ST8 so as to have equal time. In such a process, for example, in each of the work stations ST1 to ST8, work exceeding the time for which the total stop time is equally distributed is equally distributed to the other (especially downstream) work stations ST1 to ST8. This can be done by allocating the time.

  However, the processing example of work distribution is not limited to the above-described example, and may be a process that distributes at least one work content that has caused the conveyance stop in each work station ST1 to ST8 to another work station. In particular, in the production line, there may be a work order in which the work order cannot be changed. Therefore, the work contents to be redistributed within the range according to the work order and the work stations ST1 to ST8 that are the distribution destinations are specified, and the work contents are specified. Redistribution of

  According to the line work management support system configured as described above, work distribution review data 54c in which stop times are associated with each of the plurality of work stations ST1 to ST8 is generated. For this reason, the stop time can be easily grasped by distinguishing each of the work stations ST1 to ST8, and the work distribution can be reviewed more appropriately.

  In the work distribution review data 54c, registration of work contents may be omitted, and only the stop time for each work station ST1 to ST8 may be associated. Even in this case, the above effect can be obtained.

  However, if the work and the stop time that caused the work stop are associated with each work station ST1 to ST8, as in the work distribution review data 54c in the present embodiment, the worker can associate each work station ST1 to ST1. By distinguishing ST8, the work and the stop time that caused the work stop can be easily grasped, and the work distribution can be reviewed more appropriately.
