Description

[Technical field]

[0001] The present invention relates to a work management system and a work management tool for managing work in various workplaces. [Background technology]

[0002] In a workplace, when multiple people are engaged in the same work, it is necessary for each person to share information about the progress of the work. Hereinafter, such information may be referred to as work information as necessary. Conventionally, as a method for sharing work information among a plurality of personnel, the work information has been posted on a shared bulletin board and shared among each of the personnel (see, for example, Patent Document 1).

[0003] Patent Document 1 proposes a technique for posting construction information on a bulletin board at a work site, capturing the construction information with a digital camera, filing the obtained image data in a storage file by a calculation element, and linking it to CAD data, i.e., design information. Patent Document 1 also introduces the use of character information in the image data, i.e., information such as the photographing location, date, time, construction content, and part, which is posted on the bulletin board and read by the calculation element, as information to be used for filing.

[0004] [Patent Document 1] JP 2005-242653 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in a workplace, there are cases where multiple personnel are involved in the same work at different times. For example, when performing a certain task, a supervisor issues instructions to a worker, the worker performs the instructed task, and then a checker checks whether the task performed by the worker was acceptable or not.

[0006] When multiple people are involved in the same work at different times as described above, each person needs to share work information in real time in order to perform the work smoothly or to move the work to the next stage. In addition, when the work information changes, the change needs to be notified to each person quickly and reliably.

[0007] In a workplace, many tasks are generally carried out simultaneously, and each worker generally performs many tasks one after another. Therefore, the tasks for which each worker should share their progress change from moment to moment, and it is not easy to share the task information in real time among the workers involved in the tasks.

[0008] By using the technology of Patent Document 1 mentioned above, it is possible to digitize information posted on bulletin boards and information such as handwritten characters on bulletin boards, file it, and share it among personnel involved in the same work. However, the technology of Patent Document 1 alone is insufficient for each employee to share work information in real time or to notify each employee of changes in work information quickly and reliably.

[0009] The present invention has been made in consideration of the above circumstances, and has as its problem to be solved, to provide a technology that enables personnel involved in work in a workplace to share work information in real time and with a high degree of accuracy. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] As described above, the work management system of the present invention is a work management system for grasping the progress of work in a workplace, and includes an instruction card, a notice board, an imaging element, and a calculation element. On the other hand, the work management tool of the present invention is a work management tool for grasping the progress of work in a workplace, and has an instruction card and a bulletin board. It can be said that the work management tool of the present invention focuses on the instruction card and the bulletin board in the work management system of the present invention. In other words, the work management tool of the present invention is one aspect of the instruction card and the bulletin board in the work management system of the present invention. Hereinafter, as necessary, the instruction card and the bulletin board in the work management system of the present invention may be referred to as the work management tool, the work management tool of the present invention, etc.

[0016] In the work management system of the present invention, the instruction cards display the contents of the work, and the bulletin board has a posting area for posting the instruction cards. Hereinafter, the "contents of the work" may be abbreviated to "work details" as necessary.

[0017] In the work management system of the present invention, the bulletin board can post instruction cards in a bulletin board area in a number of different states. Therefore, the work management system of the present invention has the advantage that, even when multiple personnel are involved in the same work at different times, each of the personnel involved in the work can share the work information displayed on the bulletin board in real time. In addition, there is also the advantage that each of the personnel can visually and intuitively recognize the pattern of the work information from the state of the instruction card posted on the bulletin board.

[0018] An example will be described in which multiple personnel, including an instructor, an operator, and an inspector, are involved in the same work at different times. In this case, first, the person in charge posts an instruction sign in the posting area of ​​the bulletin board. At this time, the instruction sign and the bulletin board display the work information. Since the bulletin board and the instruction signs posted on the bulletin board are shared by the personnel involved in the same work, the work information is shared in real time with each of the personnel.

[0019] As mentioned above, the task details are displayed on the instruction card, so the task information at this time includes the task details and also includes, as the task progress status, the fact that instructions on the task details have been issued to the worker.

[0020] When a worker finishes a task, he or she changes the status of the instruction sign in the bulletin board. This updates the task information displayed by the instruction sign and bulletin board, and the updated task information is shared with each worker in real time.

[0021] The work information at this time includes, in addition to the work content, the progress status of the work, which indicates that the worker has completed the work.

[0022] Based on the work information updated as described above, the inspector checks the work of the workers. Then, when the inspector completes the check, he or she changes the status of the instruction sign in the bulletin board. This updates the work information displayed by the instruction sign and bulletin board again, and the updated work information is also shared with each worker in real time.

[0023] The work information at this time includes, as the progress status of the work, the fact that the work, including checking, has been completed.

[0024] In this way, the work management system of the present invention allows multiple personnel who are involved in the same work at different times to share updates and changes to work information in real time. Also, the work management system of the present invention can change the state of the instruction sign posted on the bulletin board for each stage of the work, i.e., each time the work information is updated, so that each personnel can visually and intuitively recognize that the work information has been updated. As a result, the work management system of the present invention makes it possible to quickly and reliably inform each personnel of the work information.

[0025] The work management system of the present invention includes an imaging element and a calculation element in addition to the bulletin board and the instruction signs described above. The imaging element continuously or intermittently acquires image data of the entire bulletin board in real time, and the calculation element performs image analysis on the image data acquired by the imaging element.

[0026] The image data of the entire notice area acquired by the imaging element includes information on the notice boards posted in the notice area, the work contents displayed on the notice boards, the notice status of the notice boards, etc. The calculation element performs image analysis on the image data including this information. Therefore, the calculation element can grasp the progress of the work based on the state of the indication plate that changes relative to the display area.

[0027] The indication signs are posted on the bulletin board in a number of different states, so that when the computing element performs image analysis of image data including the indication signs, it is easy to recognize the pattern of the state of the indication sign, and it is possible to easily grasp the work information from the state of the indication sign. According to the work management system of the present invention, it is possible to appropriately manage work based on the work information grasped by the computing element.

[0028] The progress of the work grasped by the calculation element can be shared not only with the personnel involved in the work, but also with other personnel involved in the next stage of the work, which is advantageous for smoothly advancing the work to the next stage.

[0029] The work management tool of the present invention has a bulletin board and instruction cards, and constitutes a part of the work management system of the present invention described above. With such a work management tool of the present invention, like the work management system of the present invention described above, multiple personnel who are involved in the same work at different times can share updates and changes to work information in real time. In addition, the work management tool of the present invention can also change the state of the instruction cards posted on the bulletin board every time the work information is updated, which has the effect of allowing each personnel to visually and intuitively recognize that the work information has been updated. As a result, the work management tool of the present invention can also quickly and reliably inform each personnel of the work information.

[0030] There are two aspects of the work management tool of the present invention. In the work management tool of the first aspect, the posting area has a first posting section for posting an instruction sign when the work is in a first stage, and a second posting section for posting an instruction sign when the work is in a second stage. The instruction sign changes state between at least two different states, a state displayed on the first posting section and a state displayed on the second posting section.

[0031] According to the work management tool of the first aspect, each worker can easily recognize the pattern of the sign posted on the bulletin board, i.e., whether the sign is in the first bulletin board section or the second bulletin board section. Each worker can easily and reliably grasp the work information in real time, that is, when the sign is in the first bulletin board section, the work is in the first stage, and when the sign is in the second bulletin board section, the work is in the second stage. Similarly, when the calculation element performs image analysis on image data including the indicator plate, the calculation element can easily recognize the pattern of the state of the indicator plate, making it possible to grasp work information in real time more easily and more reliably.

[0032] In the work management tool of the second embodiment, the design of the instruction sign is different when it is displayed in a first direction from when it is displayed in a second direction perpendicular to the first direction. By displaying the instruction sign in the first direction when the work is in the first stage and displaying the instruction sign in the second direction when the work is in the second stage, the instruction sign changes between at least two different states.

[0033] According to the work management tool of the second aspect, each worker can easily recognize the pattern of the state of the instruction sign posted on the bulletin board, i.e., whether the instruction sign is posted in the first direction or the second direction. Each worker can easily and reliably grasp the work information in real time, that is, if the instruction sign is posted in the first direction, the work is in the first stage, and if the instruction sign is posted in the second direction, the work is in the second stage. Similarly, when the calculation element performs image analysis on image data including the indicator plate, the calculation element can easily recognize the pattern of the state of the indicator plate, making it possible to grasp work information in real time more easily and more reliably.

[0034] The work management system and work management tool of the present invention will be described below in detail with respect to each of their components. Note that the description of the instruction cards and bulletin boards in the work management system of the present invention can be read as the description of the instruction cards and bulletin boards in the work management tool of the present invention.

[0035] Hereinafter, unless otherwise specified, the numerical range "x to y" described in this specification includes the lower limit x and the upper limit y in the range. The numerical range can be formed by arbitrarily combining these upper and lower limit values, as well as the numerical values ​​listed in the embodiment. Furthermore, the numerical values ​​arbitrarily selected from within the numerical range can be the upper and lower limit numerical values.

[0036] The work management system of the present invention is a work management system for grasping the progress of work in a workplace. There are no particular limitations on the type of work site where the work management system of the present invention is carried out, the work to be managed by the work management system of the present invention, and the progress status thereof, and any work in any work site may be used.

[0037] The work management system of the present invention includes an instruction card, a bulletin board, an imaging element, and a computing element. Of these, the instruction sign may be any sign that displays the work content, and there are no particular limitations on the material, size, color, or style of displaying the work content. Examples of materials for the indication tags include resin, wood, paper, metal, etc. The work contents may be printed or handwritten on the indication tags. Alternatively, the indication tags may be provided with an electronic display device such as an LCD screen to electronically display the work contents. The color of the indication tags is not particularly limited, but it is preferable that indication tags in the same work management system are the same color, and it is also preferable that indication tags in related work management systems are the same color.

[0038] The shape of the indicator card is not particularly limited, but in order to easily recognize the pattern of the indicator card state, it is preferable that the indicator card be a rectangle with a different aspect ratio. Specifically, it is particularly preferable that the length of the indicator in a first direction differs from the length in a second direction perpendicular to the first direction by 1.5 times or more, 2 times or more, or 2.5 times or more.

[0039] Also, displaying a portion of a sign in a different color from the remaining portion of the sign is useful for easily recognizing patterns of the work content and state of the sign displayed on the sign. Specifically, a portion of the indication card may be displayed in white and another portion in black, or a portion of the indication card may be displayed in white and another portion in red, etc.

[0040] In order to make it easier to recognize the pattern of the work content and the state of the indicator card displayed on the indicator card, it is also useful to paint one end and the other end of a rectangular indicator card with different aspect ratios a different color in the longitudinal direction, or to paint one end and the other end of a rectangular indicator card with different aspect ratios a different color in the transverse direction.

[0041] When a part of a sign is displayed in a different color from the other part of the sign, the work content displayed on the part of the sign and the work content displayed on the other part of the sign may be the same color or different colors.

[0042] The bulletin board only needs to have a posting area for posting instruction signs. The bulletin board may have only one posting area, or may have multiple posting areas. In other words, the bulletin board may be shared by multiple work management systems.

[0043] There are no particular limitations on the material, shape, posting method, etc. of the bulletin board. For example, a magnetic bulletin board may be used, and the indication cards may have magnets integrated therein. The indication cards may be attached to the bulletin board by magnetic force, and posted in the notice area of ​​the bulletin board.

[0044] Alternatively, a plurality of pockets or fixtures may be provided in the bulletin board's bulletin board area, and the instruction tags may be posted in the bulletin board's bulletin board area by inserting the instruction tags into the pockets or fixing them to the fixtures. The method of posting instruction tags on the bulletin board is not limited to this, and various other methods may be adopted.

[0045] The work management system of the present invention may have only one instruction sign or may have multiple instruction signs. Also, it may have only one bulletin board or may have multiple bulletin boards. In other words, the work management system of the present invention may use only one instruction sign for one task or may use multiple instruction signs. Also, it may use only one bulletin board for one task or may use multiple bulletin boards.

[0046] In the work management system of the present invention, the bulletin board is capable of posting instruction signs in a posting area in a number of different states.

[0047] For example, it is preferable that the posting area has a first posting section for posting an instruction sign when the work is in a first stage, and a second posting section for posting an instruction sign when the work is in a second stage.

[0048] In this case, when the first stage of work is completed, the worker in the first stage simply posts the instruction sign on the first display area, and when the second stage of work is completed, the worker in the second stage simply moves the instruction sign from the first display area to the second display area.

[0049] For example, it is also preferable that the design of the instruction sign be different when it is displayed in a first direction from when it is displayed in a second direction perpendicular to the first direction. In this case, it is preferable to display the instruction sign in the first direction when the work is in the first stage, and display the instruction sign in the second direction when the work is in the second stage.

[0050] In this case, when the first stage of the work is completed, the worker in the first stage simply displays the instruction tag in a first orientation, and when the second stage of the work is completed, the worker in the second stage simply changes the state of the instruction tag from the first orientation to the second orientation.

[0051] The work may have only the above two stages, or may have three or more stages. In either case, it is sufficient that the state of the instruction sign can be changed in the display area according to the stages of the work.

[0052] For example, as described above, when performing a certain task, a supervisor issues instructions to a worker, the worker performs the instructed task, and a checker checks whether the task performed by the worker is acceptable or not. In this case, the supervisor corresponds to the first stage worker, the worker corresponds to the second stage worker, and the checker corresponds to the final stage worker.

[0053] In this case, the checker, i.e., the worker in the final stage, after the end of the final stage, may move the instruction tag to a third posting section different from the first posting section and the second posting section, or may remove it from the bulletin board. Alternatively, the worker in the third stage may turn the instruction tag over and post it on the first posting section or the second posting section.

[0054] Alternatively, the worker in the final stage may change the state of the instruction tag to a third direction different from the first direction and the second direction, or may remove it from the bulletin board after the completion of the final stage. Alternatively, the worker in the third stage may turn the instruction tag over and post it in the posting area.

[0055] In either case, the state of the instruction sign changes in the display area according to the steps of the work.

[0056] The imaging element captures image data of the entire display area continuously or intermittently in real time. The imaging element only needs to be able to acquire image data of the entire posting area, and image data of the entire posting area here means image data that can directly or indirectly identify the posting area to be imaged and the indicator signs posted in the posting area. The image data of the entire notice area can also be image data acquired by an imaging element installed in a position that includes the entire notice posted on the notice area to be imaged.

[0057] The work management system of the present invention may have only one imaging element, or may have a plurality of imaging elements.

[0058] The imaging element may continuously or intermittently acquire image data of the bulletin board area. For example, a bulletin board may be provided with multiple bulletin board areas, and one imaging element may rotate around and capture each bulletin board area in a predetermined order. In this case, the imaging element captures each bulletin board area at a predetermined interval, and image data for each bulletin board area is acquired intermittently.

[0059] In this case, a corresponding instruction sign is posted in each bulletin board, and multiple work management is performed on one bulletin board. In this case, one imaging element can be shared by multiple work management systems, which is advantageous in terms of cost.

[0060] The imaging element only needs to acquire image data of the entire posting area continuously or intermittently in real time, and such an imaging element may be capable of acquiring image data as a moving image or as a still image.

[0061] The calculation element is capable of image processing of the image data acquired by the imaging element, and is capable of grasping the progress of work based on the state of the instruction sign for the posting area on the image data, and its structure and configuration are not particularly limited.

[0062] An example of such a computing element is a computer having a computing and control device such as a CPU, and a storage device such as a memory or a hard disk.

[0063] The computing element is preferably connected by wire or wirelessly so that data from the imaging element can be acquired in real time, in order to process image data acquired in real time by the imaging element.

[0064] The work management system and work management tool of the present invention will be described below with specific examples.

[0065] Example 1 Fig. 1 is an explanatory diagram for typically explaining the indication plate, bulletin board, imaging element, and calculation element in the work management system and work management tool of Example 1. Fig. 2 is an explanatory diagram for typically explaining the indication plate in the work management system and work management tool of Example 1. Figs. 3 to 6 are explanatory diagrams for typically explaining the state in which work management is performed using the work management system and work management tool of Example 1. Hereinafter, each direction mentioned in the first embodiment refers to each direction shown in FIG.

[0066] The work management system 1 and the work management tool 10 of the first embodiment are for managing the work of preparing luggage to be loaded onto a truck at a luggage storage facility 110. The luggage storage facility 110 corresponds to a work site in the work management system 1 of the present invention.

[0067] 1, the work management system 1 of the first embodiment includes an instruction card 2, a bulletin board 3, an imaging element 4, and a calculation element 5. Of these, the instruction card 2 and the bulletin board 3 are the work management tool 10 of the first embodiment.

[0068] Bulletin board 3 has a plurality of bulletin board areas 30. The number of bulletin board areas 30 corresponds to the number of tasks managed by bulletin board 3. Each bulletin board area 30 is assigned a different number.

[0069] Each of the notice areas 30 on the bulletin board 3 is made of a magnetic material, and the indicators 2 each having a magnet attached thereto are attached to the corresponding notice area 30 by magnetic force and are displayed in that notice area 30.

[0070] 2, the instruction card 2 has a long rectangular shape and includes a base (not shown) made of a magnet and a display unit 20 made of paper and attached to the base. The work content is printed on the display unit 20.

[0071] The longitudinal length of the instruction sign 2 is about 2.5 times the lateral length of the instruction sign 2. One longitudinal end portion of the display section 20 of the instruction sign 2 is black, and the other longitudinal end portion of the display section 20 of the instruction sign 2 is white. The instruction sign 2 displays the work content 21, such as the work sequence number, the destination of the package, the truck number of the truck carrying the package, and the scheduled work time. The work sequence number refers to the order in which the target work is to be performed among all the work to be performed in the workplace.

[0072] As shown in Fig. 1, the bulletin board 3 in the work management system 1 of the first embodiment has multiple bulletin board areas 30, and one instruction sign 2 is posted in each of the bulletin board areas 30. Therefore, it can be said that the bulletin board 3 is shared by multiple work management systems 1. In other words, the work management system 1 of the first embodiment is part of multiple work management systems 1 that manage work in the same work area. The work management system 1 of the first embodiment uses the bulletin board 3 with the bulletin board area 30 assigned the number 1.

[0073] The imaging element 4 is a digital camera that intermittently captures image data as still images, and has a swivel function that repeatedly captures images of each bulletin board area 30 on the bulletin board 3 in ascending order of the assigned numbers. In the work management system 1 of the first embodiment, the imaging element 4 visits each bulletin board area 30 every 30 seconds. Therefore, the imaging element 4 captures image data intermittently every 30 seconds.

[0074] As shown in FIG. 1, the imaging element 4 is wirelessly connected to the computing element 5.

[0075] The computation element 5 is a computer equipped with AI, and the imaging element 4 is controlled by the computation element 5 to capture an image of the bulletin board area 30 of the bulletin board 3 and acquire image data. The image data is transmitted to the computation element 5 and stored therein.

[0076] The calculation element 5 corrects distortion of the image data and provides it for image analysis. The image data acquired by the imaging element 4 is corrected for distortion, and the image of the notice area 30 and the sign 2 posted in the notice area 30 on the image data is made closer to a realistic shape.

[0077] A specific process of performing work management using the work management system 1 and the work management tool 10 of the first embodiment will be described below.

[0078] The work management system 1 of the first embodiment is for managing the work of preparing luggage to be loaded onto trucks in a luggage storage facility 110.

[0079] Specifically, the work of preparing packages to be loaded onto a truck includes a step in which an instructor gives work instructions, a step in which a worker prepares the packages, and a step in which a checker checks the prepared packages.

[0080] As shown in FIG. 3, at the start of work, the notice area 30 on the bulletin board 3 to which the number 1 is assigned has no instruction sign 2 posted thereon and is therefore empty.

[0081] After starting the work, the instructor first gives instructions for the work. At this time, the instructor posts the instruction tag 2 corresponding to the work in the posting area 30 to which the number 1 is assigned, with the longitudinal direction facing up and down (FIG. 4).

[0082] The bulletin board 3 is located in a position where it can be seen by the personnel involved in the work, i.e., the instructor, the worker, and the checker. When the instruction sign 2 is posted in the posting area 30 with its longitudinal direction facing up and down, work information that a work instruction has been issued is shared in real time among the instructor, the worker, and the checker.

[0083] When the instruction sign 2 is posted, the worker checks the work content 21 displayed on the instruction sign 2 and moves the specified luggage to the specified position. When the work is completed, the worker changes the state of the instruction sign 2 so that the short side faces up and down, and posts it in the posting area 30 assigned the number 1 (FIG. 5).

[0084] When the instruction sign 2 is posted in the posting area 30 with its short side facing up and down, work information that the work has been completed is shared in real time among the instructor, the worker, and the checker.

[0085] The checker checks the work based on the work information. Specifically, the checker checks whether the work can be done by comparing the number and type of luggage collected by the worker with the work content 21 displayed on the instruction plate 2. If the number and type of luggage collected by the worker are correct, the checker removes the instruction plate 2 posted in the posting area 30 to which the number 1 is assigned (FIG. 6). When the instruction tag 2 is removed from the display area 30, the instructor, the worker, and the checker share in real time the work information that the check has been completed and that the number and types of luggage collected by the worker are correct.

[0086] In this work, the final worker is the checker, so the work ends when the check is completed.

[0087] If the inspector determines that the number or type of luggage collected by the worker is incorrect, the inspector will feed that information back to the worker, change the state of the instruction sign 2 so that the longitudinal direction is facing up or down, and post it again in the posting area 30 assigned the number 1 (Figure 4). The worker who receives feedback from the checker performs the task again, and when the task is completed, the worker changes the state of the instruction tag 2 so that the short side faces up and down, and posts it again in the posting area 30 assigned with the number 1 (Fig. 5).The checker then checks again, and if the number and type of luggage the worker has collected are correct, the checker removes the instruction tag 2 posted in the posting area 30 assigned with the number 1 from the posting area 30 (Fig. 6).

[0088] Meanwhile, while the above steps are being performed, the imaging element 4 captures an image of the notice area 30 assigned the number 1 and acquires image data. The image data acquired by the imaging element 4 is transmitted to the calculation element 5 and stored therein.

[0089] The imaging element 4 rotates around each display area 30 and obtains high-resolution image data for each display area 30. Therefore, the image data clearly shows the work content 21 displayed on the instruction sign 2, specifically, the work sequence number, the destination of the package, the truck number of the truck carrying the package, the scheduled work time, etc.

[0090] The calculation element 5 uses OCR to capture these various work contents 21 captured in the image data and saves them in a storage file in real time. At the same time, the calculation element 5 grasps the work information based on the state of the indication plate 2 and saves it in a storage file in real time together with the above work contents 21.

[0091] The saved file can be accessed not only by the personnel involved in the work, but also by other personnel involved in the next stage of the work. As a result, the work management system 1 of the first embodiment allows many personnel to share the work content 21 and its progress in real time.

[0092] In this way, the work management system 1 and the work management tool 10 of the first embodiment enable the personnel involved in work at the workplace to share work information in real time with a high degree of accuracy.

[0093] Example 2 Except for the shape of the bulletin board, the work management system and work management tool of the second embodiment are generally the same as those of the first embodiment. Therefore, the work management system and work management tool of the second embodiment will be described below, focusing on the differences from the first embodiment. 7 to 9 are explanatory diagrams for explaining in a schematic manner how work management is performed using the work management system and work management tool of the second embodiment.

[0094] As shown in FIGS. 7 to 9, in the work management system 1 and the bulletin board 3 in the work management tool 10 of the second embodiment, the bulletin board area 30 has two bulletin sections.

[0095] One of the display units, the first display unit 31, is an area for displaying the instruction sign 2 when the work is in the first stage, more specifically, when the instructor is giving work instructions. The other display unit, the second display unit 32, is an area for displaying the instruction sign 2 when the work is in the second stage, more specifically, when the worker has finished the work. The first display unit 31 and the second display unit 32 are arranged on the left and right.

[0096] In the work management system 1 and work management tool 10 of Example 2, the instruction sign 2 changes state among three different states: a state displayed on the first posting section 31 (Figure 8), a state posted on the second posting section 32 (Figure 9), and a state removed from the posting area 30 (Figure 7).

[0097] The work management system 1 and the work management tool 10 of the second embodiment also enable the personnel involved in work at the workplace to share work information in real time with a high degree of accuracy.

[0098] Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it is possible to implement the present invention by appropriately extracting and combining elements described in the embodiments, and to make various modifications without departing from the spirit of the present invention. Furthermore, the specification of the present invention discloses not only the citation relationships of each claim at the time of the initial application, but also a technical idea that appropriately combines the matters described in each claim.
