Description

The present invention relates to a work management system.

In recent years, work management systems for managing work performed by humans have been developed. For example, the work management system of Patent Document 1 includes an imaging device and an information processing device. The imaging device captures an image of the entire workpiece on which tightening work is to be performed. The information processing device pre-stores position data of adjustment jigs such as bolts on which work is to be performed. The information processing device also derives position data of the bolts on which work is to be performed from the imaging data transmitted from the imaging device. Next, the information processing device compares the derived position data with the pre-stored position data to determine whether or not all bolts have been tightened. This prevents bolts from being forgotten to be tightened.

JP 2010-42491 A

When capturing an image of a large workpiece in its entirety, the imaging device must be separated from the workpiece. However, if the imaging device is separated, the worker is placed between the imaging device and the workpiece. As a result, the bolt itself cannot be captured, and position data for the bolt on which the work was performed cannot be obtained.

As an alternative, a worker could be fitted with an imaging device to capture an image of the bolt he or she is manipulating. With this approach, the entire workpiece is not imaged, so the relative position of the imaging range cannot be determined. Therefore, it is necessary to assign an identifier, which is position information, to the bolt. However, the identifier may be obscured by the work tools used.

The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a work management system that can identify the adjustment jig being operated even if the adjustment jig's identifier is hidden by the work tool.

In order to achieve the above object, a work management system according to one aspect of the present disclosure includes a plurality of adjustment jigs that adjust equipment and are arranged in one direction, an identifier that assigns a color to each of the adjustment jigs, an imaging device that generates imaging data in which a portion of the adjustment jigs among the plurality of adjustment jigs are imaged, and an information processing device that acquires the imaging data. The identifiers include a reference identifier that assigns the same reference color to each of the adjustment jigs that are arranged in a predetermined number consecutively among the plurality of adjustment jigs, a first special identifier that assigns a first identification color different from the reference color to the adjustment jigs, a second special identifier that assigns a second identification color different from the reference color to the adjustment jigs, and a third special identifier that assigns a third identification color different from the reference color to the adjustment jigs. In the one direction, the first special identifier, the consecutively arranged multiple reference identifiers, the second special identifier, the consecutively arranged multiple reference identifiers, and the third special identifier are arranged in this order. The combination of the first identification color, the second identification color, and the third identification color from the one direction is only one set among all the identifiers. The information processing device identifies an adjustment jig in which any of the first special identifier, the second special identifier, the third special identifier, and the reference identifier cannot be identified from the imaging data as a work adjustment jig that has been worked on by a worker.

The work management system disclosed herein makes it possible to identify the adjustment tool being operated even if the identifier is hidden by the work tool.

As one aspect of the above-mentioned work management system, if the number of adjustment jigs that fall within the imaging range of the imaging device is NY, and the number of the reference identifiers that are sandwiched between the first special identifier and the third special identifier is NX, the following formula (1) is satisfied.

(Equation 1)
NY≧NX+3 Equation (1)

According to this aspect, even if the second identifier is hidden by the work tool, the first and second identifiers on either side of it are captured by the imaging device. Therefore, the adjustment jig hidden by the work tool can be identified.

As one aspect of the above work management system, the information processing device includes a calculation unit and a storage unit. The storage unit stores an arrangement pattern of the first identification color, the second identification color, the third identification color, and the reference color. The calculation unit identifies the work adjustment jig from all of the adjustment jigs based on a color combination from one direction of any two of the first identification color, the second identification color, and the third identification color that sandwich the work tool identified from the imaging data, the number of the reference colors from the work tool to the two colors, and the color arrangement pattern.

According to this aspect, even if the range that the imaging device can capture is smaller than the range of all the adjustment jigs, the calculation unit can identify the adjustment jig being worked on.

As one aspect of the above work management system, a work tool that transmits work volume data is further provided. The work adjustment tool, the work time, and the work volume data are stored in association with each other in the memory unit.

According to this aspect, it is possible to grasp the workload data of the identified adjustment jig.

As one aspect of the above-mentioned work management system, a measuring device is further provided for measuring evaluation data of the products produced by the equipment. The evaluation data and the work amount data are associated and stored in the storage unit.

According to this aspect, it is possible to understand the relationship between the workload data and the evaluation data of the identified adjustment jig.

The work management system disclosed herein can identify the adjustment jig being operated even if the adjustment jig's identifier is hidden by the work tool.

The present invention will be described in detail below with reference to the drawings. Note that the present invention is not limited to the following modes for carrying out the invention (hereinafter referred to as embodiments). Furthermore, the components in the following embodiments include those that a person skilled in the art can easily imagine, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the following embodiments can be combined as appropriate.

Figure 1 is a diagram showing the overall configuration of a resin film manufacturing apparatus to which the work management system of this embodiment is applied. The work management system 100 includes a plurality of adjustment bolts 1, an identifier 10, a work tool 20 (see Figure 5), an imaging device 30 (see Figure 6), an information processing device 40, and a thickness meter 97. The work management system 100 of this embodiment is also applied to a resin film manufacturing apparatus 90 that manufactures a resin film 91. The resin film manufacturing apparatus 90 includes a die device 92, a cast roll 93, a touch roll 94, a transport roll 95, a heat treatment device 96, and a roll winder 98.

The nozzle device 92 is a T-die. Molten thermoplastic resin is supplied to the nozzle device 92 from an extruder (not shown). The nozzle device 92 extrudes the thermoplastic resin from a slit (not shown) in the lip portion 99. This causes the thermoplastic resin to be formed into a film. The film-like thermoplastic resin is then cooled and solidified to become a resin film 91.

The resin film 91 is brought into close contact with the cast roll 93 by the touch roll 94. Next, the resin film 91 passes through the transport roll 95 and the heat treatment device 96, where it is stretched and heat-set. Next, the thickness of the resin film 91 is measured by the thickness meter 97. Finally, the resin film 91 is wound up by the roll winder 98.

The thickness meter 97 described above is a measuring device that acquires evaluation data of the product (resin film 91) manufactured by the resin film manufacturing apparatus 90. The thickness meter 97 associates the measurement time, the thickness of the resin film 91, and the transport speed of the resin film 91 (the transport speed by the cast roll 93, touch roll 94, and transport roll 95) and transmits them to the information processing apparatus 40. The memory unit 41 of the information processing apparatus 40 then stores the measurement time, the thickness of the resin film 91, and the transport speed of the resin film 91 as evaluation data D102 (see FIG. 10).

The resin film 91 has a different thickness at each location in the width direction (see Figures 11 and 12). Therefore, the thickness meter 97 measures all locations in the width direction of the resin film 91. The thickness meter 97 then transmits to the information processing device 40 the position data indicating which part in the width direction of the resin film 91 corresponds to the measurement time, the thickness of the resin film 91, and the conveying speed of the resin film 91. Therefore, the evaluation data D102 stored in the memory unit 41 is also divided and stored for each part in the width direction of the resin film 91, such as first evaluation data D1021, second evaluation data D1022, third evaluation data D1023, etc. (see Figure 10).

The adjustment bolt 1 is provided in a device called a cap device 92. The adjustment bolt 1 is an adjustment part for adjusting the width of a slit (not shown) in a lip portion 99 of the cap device 92. The width direction of the slit in the lip portion 99 is the thickness direction of the resin film 91. In this embodiment, a plurality of adjustment bolts 1 are provided for the cap device 92. The plurality of adjustment bolts 1 are arranged in one direction X for the cap device 92. The one direction X in which the plurality of adjustment bolts 1 are arranged is the direction indicated by the arrow in FIG. 1 and is parallel to the width direction of the resin film 91. The number of adjustment bolts 1 in this embodiment is 49.

Figure 2 is an enlarged perspective view of a portion of the multiple adjustment bolts provided in the nozzle device. As shown in Figure 2, the adjustment bolt 1 has a head 2 with a hexagonal outer shape and a cylindrical portion 3 extending from the head 2 toward a lip portion 99 (not shown in Figure 2). When the adjustment bolt 1 is rotated in one rotation direction, the width of the slit in the lip portion 99 becomes smaller, and the thickness of the resin film 91 becomes thinner. On the other hand, when the adjustment bolt 1 is rotated in the other rotation direction, the width of the slit in the lip portion 99 becomes larger, and the thickness of the resin film 91 becomes thicker.

The identifier 10 is a colored paint applied to the adjustment bolt 1. As shown by the hatching in FIG. 2, the identifier 10 of this embodiment imparts color to the end face 2a of the head 2 and the end face 3a of the cylindrical portion 3. The end faces 2a and 3a are the parts that overlap with the work tool 20 during the adjustment work (see FIGS. 8 and 9). The identifier 10 is not limited to paint, and may be a sticker, a lid, a tag, etc.

The identifier 10 includes a reference identifier 11 that assigns a reference color, and a special identifier 12 that assigns an identification color different from the reference color. In this embodiment, the reference color is yellow. The identification colors are red 12R, blue 12B, green (not shown in FIG. 2), and white (not shown in FIG. 2). Based on the arrangement position of the adjustment bolt 1 to which the special identifier 12 is assigned, one of red 12R, blue 12B, green (not shown in FIG. 2, and FIG. 7 to FIG. 9), and white (not shown in FIG. 2, and FIG. 7 to FIG. 9) is selected. The reference color may be the background color of the adjustment bolt 1. The reference color is not limited to yellow, and is preferably a color that is not transparent. For example, if the reference color is painted with a colored paint, the difference between the background and the reference color is easily distinguished from the image data of the image capture device 30.

Identifiers 10 are assigned to all adjustment bolts 1. Of these, 38 adjustment bolts 1 are assigned a standard color. Eleven adjustment bolts 1 are assigned an identification color. Thus, identifiers 10 with a special color different from the standard color are called special identifiers 12, and there are eleven special identifiers 12. Hereinafter, the eleven special identifiers 12 may be referred to as the first special identifier, second special identifier, third special identifier, fourth special identifier, fifth special identifier, sixth special identifier, seventh special identifier, eighth special identifier, ninth special identifier, tenth special identifier, and eleventh special identifier, in order in one direction X.

Figure 3 shows the color arrangement pattern of the identifiers stored in the storage unit of the information processing device. The arrangement pattern of the identifiers 10 is, in order from one direction X, the first special identifier 12, three reference identifiers 11, the second special identifier 12, four reference identifiers 11, the third special identifier 12, four reference identifiers 11, the fourth special identifier 12, four reference identifiers 11, the fifth special identifier 12, four reference identifiers 11, the sixth special identifier 12, four reference identifiers 11, the seventh special identifier 12, four reference identifiers 11, the eighth special identifier 12, four reference identifiers 11, the ninth special identifier 12, four reference identifiers 11, the tenth special identifier 12, three reference identifiers 11, and the eleventh special identifier 12. Therefore, the first and last of the identifiers 10 in one direction X are special identifiers 12. In addition, the number of adjustment bolts 1 with reference identifiers 11 arranged between the special identifiers 12 is three or four.

As shown in FIG. 3, the storage unit 41 of the information processing device 40 stores color array pattern data D100 of the identifiers 10 (see FIG. 3). The array pattern data D100 of the identifiers 10 associates the bolt number (indicated as "Bolt No." in FIG. 3) indicating the order when counting from one direction X with the color of the identifier attached to each adjustment bolt 1.

Figure 4 illustrates an arrangement pattern of the identification colors of special identifiers. In Figure 4, three identifiers arranged consecutively in any one direction X in the arrangement pattern of the identification colors of special identifiers are called the first special identifier, the second special identifier, and the third special identifier. For example, if the fifth special identifier is the first special identifier, the second special identifier is the sixth special identifier, and the third special identifier is the seventh special identifier. As shown in Figure 4, the colors assigned to the fifth special identifier, the sixth special identifier, and the seventh special identifier are green, blue, and blue in the one direction X, respectively. There is only one combination of colors in the arrangement pattern shown in Figure 4 that are green, blue, and blue in the one direction X, respectively. The arrangement pattern in Figure 4 is arranged so that the combination of the first identification color (first identification color), the second identification color (second identification color), and the third identification color (third identification color) arranged consecutively in the one direction X from any position in the arrangement pattern is only one combination among all identifiers.

In detail, the arrangement pattern of the identification colors of the special identifiers 12 is such that the combinations of identification colors from one direction X of two sequentially arranged special identifiers are all different. For example, the combination of identification colors from one direction X of the first special identifier (Bolt No. 1) and the second special identifier (Bolt No. 5) is red and blue. The combination of identification colors from one direction X of the second special identifier (Bolt No. 5) and the third special identifier (Bolt No. 10) is blue and red. Therefore, the combination of identification colors from one direction X of the first special identifier and the second special identifier is different from the combination of identification colors from one direction X of the second special identifier and the third special identifier.

In addition, the combinations of identification colors arranged in order from one direction X of two special identifiers 12 sandwiching one special identifier 12 are all different from the other positions of the color scheme pattern shown in FIG. 4. For example, the combination of identification colors from one direction X of the first special identifier 12 (Bolt No. 1) and the third special identifier 12 (Bolt No. 10) sandwiching the second special identifier 12 (Bolt No. 5) is red, red. The combination of identification colors from one direction X of the second special identifier 12 (Bolt No. 5) and the fourth special identifier 12 (Bolt No. 15) sandwiching the third special identifier 12 (Bolt No. 10) is blue, red. Therefore, the combination of identification colors from one direction X of the first special identifier and the third special identifier is different from the combination of identification colors from one direction X of the second special identifier and the fourth special identifier.

Figure 5 is a diagram showing a work tool. As shown in Figure 5, the work tool 20 is a torque wrench whose tip 21 fits into the head 2 of the adjustment bolt 1. When the work tool 20 is used, the work tool 20 wirelessly transmits work amount data associated with the work time to the information processing device 40. The work amount data of the work tool 20 includes the rotation angle and rotation torque of the adjustment bolt 1 (see Figure 10).

Fig. 6 is a diagram showing an imaging device. As shown in Fig. 6, the imaging device 30 is a camera that captures the work of the worker as a video and generates data. The imaging device 30 wirelessly transmits the imaging data and the imaging time associated with each other to the information processing device 40. The imaging device 30 is fixed to a helmet 32 by a band 31 and moves with the worker. The imaging device 30 is also fixed so as to capture an image of the worker's line of sight, that is, the work range.

Figure 7 is a diagram showing imaging data generated by the imaging device. As shown in Figure 7, the image range of the imaging device 30 is set so that it can image 11 adjustment bolts 1. In other words, the imaging device 30 cannot image all 49 adjustment bolts 1 arranged in one direction X. The imaging device 30 does not need to use a wide-angle lens, so an inexpensive lens can be used, and imaging data with little distortion can be obtained.

As shown in FIG. 3, the number of reference identifiers 11 placed between two special identifiers 12 is three or four. This means that the number of the two special identifiers 12, 12 sandwiching a certain special identifier 12, and the identifiers 10 between these two special identifiers 12, 12, is 10 or 11, all of which are included in the image range of the imaging device 30. In other words, the number of reference identifiers 11 is adjusted so that even if a certain special identifier 12 is hidden by the work tool 20, the special identifiers 12 on both sides of it are captured by the imaging device 30.

The information processing device 40 is a so-called computer, and has an input interface, an output interface, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a storage unit 41, and a display device 43. The input interface receives the work amount data D101 (see FIG. 10) of the work tool 20, the imaging data 30D (see FIG. 7) of the imaging device 30, and the evaluation data D102 (see FIG. 10) including the thickness data of the thickness gauge 97, via a wired or wireless connection or a recording medium. The display device 43 is connected to the output interface. The CPU, ROM, RAM, and storage unit 41 are connected by a bus. The ROM stores programs such as the BIOS (Basic Input Output System). The storage unit 41 is, for example, a hard disk drive (HDD) or flash memory, and stores an operating system program and application programs. The CPU is a computing means, and realizes the functions of the computing unit 42 by executing programs stored in the ROM and the storage unit 41 while using the RAM as a work area. The storage unit 41 may be built-in or external, and the RAM may be used as temporary storage, or it may be a storage device or server on a network.

The calculation unit 42 identifies the adjustment bolt 1 operated by the worker based on the image data 30D (see FIG. 7). In the first step of the processing process of the calculation unit 42, the work tool 20 is identified from the image data 30D. In the second step, two special identifiers 12 that sandwich the work tool 20 are identified from the image data 30D. Next, the combination of identification colors from one direction X of the identified two special identifiers 12 is identified. The calculation unit 42 also identifies the number of reference identifiers 11 between the work tool 20 and the two special identifiers 12. In addition, the calculation unit 42 calculates the number of adjustment bolts 1 interposed between the two special identifiers 12. In the third step, the calculation unit 42 compares the combination of identification colors from one direction X, the number of adjustment bolts 1 interposed between the identified two special identifiers 12, the number of reference identifiers 11, and the color arrangement pattern data D100 in the memory unit 41 to identify the adjustment bolt 1 that has been operated.

Figure 8 shows the first image data captured during work. In the following description, two specific examples are given to explain the details of the processing by the calculation unit 42. In Figure 8, one of the adjustment bolts 1 is hidden by the work tool 20. Specifically, one of the special identifiers 12 described above is hidden by the work tool 20. First, as a first step, the calculation unit 42 identifies the work tool 20 in the center of the image data 30D1. As a second step, the calculation unit 42 identifies two special identifiers 12, 12 that sandwich the work tool 20. Next, the calculation unit 42 identifies a combination of identification colors (blue 12B, red 12R) of the special identifiers 12, 12 from one direction X. Next, the calculation unit 42 identifies the number (4) of adjustment bolts 1 interposed between the work tool 20 and the special identifier 12 of red 12R, and the number (4) of adjustment bolts 1 interposed between the work tool 20 and the special identifier 12 of blue 12B. The calculation unit 42 then determines that the total number of adjustment bolts 1 between the blue 12B special identifier 12 and the red 12R special identifier 12 is nine.

In the third step, the calculation unit 42 searches the color arrangement pattern data D100 stored in the memory unit 41 for a position where the combination of identification colors, blue 12B and red 12R, is arranged from one direction X, and nine identifiers 10 are arranged between blue 12B and red 12R. As a result, the calculation unit 42 identifies the special identifier 12 of blue 12B as the identifier 10 attached to bolt No. 5. The calculation unit 42 also identifies the special identifier 12 of red 12R as the identifier 10 attached to bolt No. 15. As a result, the calculation unit 42 determines that the adjustment bolt 1 of bolt No. 10, which is the fifth from bolt No. 5 in one direction X and the fifth from bolt No. 15 in the opposite direction, is the adjustment bolt 1 that has been adjusted during work. In this way, although bolt No. 10 hidden by the work tool 20 cannot be identified from the image data 30D, the work management system 100 determines that bolt No. 10 is identified as the adjustment bolt 1 that the worker performed the work on.

As described above, the information processing device 40 identifies the adjustment bolt 1 in which any of the first special identifier 12, the second special identifier 12, the third special identifier 12, and the reference identifier 11 contained in the imaging data 30D cannot be identified from the imaging data 30D as the adjustment bolt worked on by the worker.

Figure 9 shows the second image data captured during work. In the example shown in Figure 9, one of the adjustment bolts 1 is hidden by the work tool 20. Specifically, one of the reference identifiers 11 described above is hidden by the work tool 20. First, as a first step, the calculation unit 42 identifies the work tool 20 in the center of the image data 30D1. As a second step, the calculation unit 42 identifies two special identifiers 12, 12 that sandwich the work tool 20 and are given two identification colors. Next, the calculation unit 42 identifies a combination of identification colors from one direction X (blue 12B, blue 12B). Next, the calculation unit 42 identifies the number (one) of adjustment bolts 1 interposed between the work tool 20 and the special identifier 12 of blue 12B on one side when viewed in one direction X. Furthermore, the calculation unit 42 determines the number (2) of adjustment bolts 1 between the work tool 20 and the blue 12B special identifier 12 on the other side of the X direction. From this, the calculation unit 42 determines that the total number of adjustment bolts 1 between the special identifiers 12 is four.

In the third step, the calculation unit 42 searches the array pattern data D100 for a combination of identification colors of blue 12B, blue 12B from one direction X, with four identifiers 10 arranged between blue 12B and blue 12B. As a result, the calculation unit 42 identifies one of the special identifiers 12 of blue 12B as the identifier 10 attached to bolt No. 25. The calculation unit 42 also identifies the other of the special identifiers 12 of blue 12B as the special identifier 12 attached to bolt No. 30. As a result, the calculation unit 42 determines that the adjustment bolt 1 of bolt No. 28, which is the third from bolt No. 25 in one direction X and the second from bolt No. 30 in the opposite direction, is the adjustment bolt 1 that was worked on.

Figure 10 is a diagram showing the work amount data, evaluation data, and adjustment bolt data stored in the memory unit. After identifying the adjustment bolt 1 that has been worked on, the calculation unit 42 stores the work time included in the image data 30D in the memory unit 41. This allows the work time to be stored in the adjustment bolt data D103 in the memory unit 41, making it possible to confirm whether or not adjustment work has been performed on the adjustment bolt 1. As shown in Figure 10, the memory unit 41 stores data for each adjustment bolt 1 separately, such as data D1 for bolt No. 1, data D2 for bolt No. 2, data D3 for bolt No. 3, data D4 for bolt No. 4, and so on.

After identifying the adjustment bolt 1 that has been worked on, the calculation unit 42 stores the work amount data D101, which is the work content, in the memory unit 41. Specifically, the rotation angle data and torque data sent from the work tool 20 are stored in the memory unit 41 together with the work time data. As a result, the work time and the work amount are associated and stored in the work amount data D101.

The calculation unit 42 also calculates the elapsed time from when the resin film 91 is pushed out from the lip portion 99 of the nozzle device 92 to when it reaches the thickness meter 97, based on the conveying speed in the evaluation data D102 in the memory unit 41. The calculation unit 42 then subtracts the elapsed time from the measurement time to calculate the molding time at which the resin film 91 is pushed out from the lip portion 99 and molded. The calculation unit 42 then stores the molding time in the evaluation data D102, which includes the thickness data.

After identifying the adjustment bolt 1 that has been worked on, the calculation unit 42 associates the thickness of the resin film 91 corresponding to this adjustment bolt 1 with the adjustment bolt data D103 and stores it in the memory unit 41. Specifically, the calculation unit 42 selects the evaluation data D102 including the thickness data, which includes the adjustment bolt 1 that has been adjusted and the thickness data of the portion corresponding to this adjustment bolt 1 in the width direction. Next, the calculation unit 42 stores, in the adjustment bolt data D103, the thickness data in which the work time of the adjustment bolt data D103 and the molding time of the evaluation data D102 match, from the evaluation data D102 including the thickness data. In this way, the adjustment bolt data D103 is stored in association with the work time and work amount of the work amount data D101 and the thickness data of the evaluation data D102.

Figure 11 is a graph showing thickness data of the resin film before adjustment. Figure 12 is a graph showing thickness data of the resin film after adjustment. The display device 43 is a display device that displays data stored in the memory unit 41. The display device 43 displays numerical values stored in the work amount data D101, evaluation data D102 including thickness data, and adjustment bolt data D103 stored in the memory unit 41. As shown in Figures 11 and 12, the display device 43 can also display a graph of the widthwise thickness of the resin film 91 at a certain time from the evaluation data D102 including thickness data. This makes it possible to understand which parts of the resin film 91 in the widthwise direction have changed and how they have changed before and after the adjustment work.

From the above, according to the work management system 100 of the embodiment, the work adjustment bolt can be identified from all the adjustment bolts 1 based on the combination of two of the first, second, and third identification colors from one direction X that sandwich the work tool 20 identified from the imaging data 30D, the number of reference colors from the work tool 20 to the two colors, and the color arrangement pattern data D100. Therefore, the manager of the resin film manufacturing device 90 can know what torque was applied to which adjustment bolt 1 and how the adjustment work was performed based on the adjustment bolt data D103 stored in the memory unit 41.

The memory unit 41 also stores the adjustment bolt 1 that was worked on, the work time, and the work amount data D101 in association with each other. This allows the administrator to grasp the amount of work done on the adjustment bolt 1 (the rotation angle and torque of the adjustment bolt).

The evaluation data D102 and the work amount data D101 are stored in association with each other in the memory unit 41. Therefore, the administrator can understand the relationship between the work amount of the adjusted adjustment bolt 1 and the thickness of the resin film 91 in that portion.

Although the preferred embodiment has been described above, the present invention is not limited to such an embodiment. The contents disclosed in the embodiment are merely examples, and various modifications are possible within the scope of the present invention. Appropriate modifications made within the scope of the present invention naturally fall within the technical scope of the present invention. All inventions that can be implemented by a person skilled in the art through appropriate design modifications based on the above-mentioned invention also fall within the technical scope of the present invention as long as they include the gist of the present invention.

For example, in the work management system of the present disclosure, the number of reference identifiers placed between special identifiers is not limited to three or four, and may be any number that satisfies the following formula (2). Note that "NY" in formula (2) is the number of adjustment bolts that fall within the imaging range of the imaging device. "NX" in formula (2) is the number of reference identifiers sandwiched between the first special identifier and the third special identifier that sandwich a certain special identifier (second special identifier).

(Equation 2)
NY≧NX+3 Equation (2)

In addition, although there are four different identification colors in the embodiment, in the work management system of the present disclosure, this number may be increased or decreased as appropriate in accordance with the total number of adjustment bolts. Also, although the number of adjustment bolts 1 in the present embodiment is 49, the number of adjustment bolts 1 is not limited to this in the work management system of the present disclosure.

For example, in the work management system 100 of the present disclosure, the adjustment bolt 1 is one of the adjustment jigs for the equipment. Instead of the adjustment bolt 1, an adjustment nut may be used. The work management system 100 of the present disclosure includes a plurality of adjustment jigs that adjust the equipment and are lined up in one direction, and may identify an adjustment jig that is not identified from the imaging data as the work adjustment jig that the worker used.

Generally, a "sheet" is defined in the JIS as a thin, flat product whose thickness is generally small relative to its length and width, and a "film" is generally a thin, flat product whose thickness is extremely small compared to its length and width, with an arbitrarily limited maximum thickness, and is usually supplied in roll form (Japanese Industrial Standard JIS K6900). However, the boundary between a sheet and a film is unclear, and in this embodiment, both are used synonymously and will be referred to uniformly as "film."
