  The communication unit 45 includes a communication interface for communicating with the management device 10, the returnable container inspection system 20, and the returnable container repair assistance system 30.

  Next, the configuration and use of the returnable container inspection system 20 will be described with reference to FIG. The returnable container inspection system 20 includes an imaging device 22, a damaged part recognition device 23, and a damage type discrimination device 24.

  Here, it is assumed that the container 27 which is an inspection target container of the returnable container inspection system 20 has a dent 28 which is a kind of breakage on the side surface due to the use of transportation, cargo handling and the like.

  The imaging device 22 acquires an image of the container 27. The imaging device 22 is configured to be able to acquire an image of the entire surface, such as the bottom surface, the side surface, the upper surface, and the inner surface of the container 27. For example, the container 27 is disposed on the frame. The imaging device 22 is disposed to be able to image the six outer surfaces of the container 27. However, in the use of the returnable container inspection system 20, the acquisition of the image is not necessarily the entire surface of the returnable container because the characteristics of the returnable container or the repair location is clear. In addition, the imaging device 22 is not limited to being held or fixedly arranged by a person in charge of inspection, use of an auxiliary device for illumination at the time of image acquisition, and being one or more. However, it is desirable to obtain stereo images with a plurality of units for each side.

  The image of the container 27 acquired by the imaging device 22 is stored in the inspection history 73 of the container 27 in association with the management number 61, together with the acquisition date, information indicating which surface or region the image is, inspection results, etc. Be done.

  The damaged part recognition device 23 is connected to the imaging device 22. After the imaging device 22 acquires the image of the container 27 corresponding to the management number 61 of the inspection target, the imaging device 22 transfers the image data to the damaged part recognition device 23. The damaged part recognition device 23 takes in the image data, and specifies the damaged part of the container 27 to be inspected by image analysis. The damaged part recognition device 23 specifies the damaged part by, for example, the surface on which the damage exists and the xy coordinates in the surface. The damaged part recognition device 23 transfers the image data and the information of the specified damaged part to the damage type discrimination device 24.

  The damage type discrimination device 24 determines the type of damage by image processing based on the received image data and information on the damaged portion. The type of breakage is, for example, holes, cracks, defects. The damage type discrimination device 24 transmits, to the terminal device 40, the image data, the information on the damaged portion, and the type of damage. The terminal device 40 registers the damage history 72 and the inspection history 73 in the management database 60 in association with the management number 61 of the container 27. Each operation of the imaging device 22, the damaged part recognition device 23, and the damage type discrimination device 24 is performed by a person in charge of inspection from the device or the terminal device 40.

  The method of the image analysis which the damage location recognition apparatus 23 and the damage classification discrimination | determination apparatus 24 perform is arbitrary. For example, the feature data of the image corresponding to the damage is prepared in the management database 60 for each type of the reusable container and the type of the damage, and the image of the captured container 27 is analyzed to match the feature data corresponding to the damage. Feature data may be extracted. In addition, when the acquired image is a stereo image, the unevenness of each outer surface is obtained, and this is compared with the unevenness obtained from the most recent image determined to be non-abnormal, and a change above the standard occurs. It may be determined that there is damage.

  The inspector can access the management apparatus 10 via the terminal device 40 near the container 27 and can control each of the returnable container inspection system 20 at hand.

  Next, the configuration and mode of use of the returnable container repair assistance system 30 will be described with reference to FIG. The returnable container repair assistance system 30 includes an optical projection device 32a and an optical projection device 32b.

  The optical projection devices 32a and 32b are fixedly disposed at positions where they can be projected onto the container 27, which is a container to be repaired, from distant locations. As shown in the figure, the returnable container repair assistance system 30 projects damage information 33 corresponding to the repair location and damage condition on the surface of the container 27. In this case, the terminal device 40 that controls the optical projection devices 32a and 32b reads information on the breakage position and the breakage mode from the breakage history 72 using the management number of the container 27 to be repaired as a key, and information indicating the breakage position, for example, An arrow pointing to the position of breakage and that damage is a hole and damage mode information indicating its size are displayed. Furthermore, repair information may be stored in the management database 60 according to the type of damage, and information on repair may be displayed. Also, in order to facilitate the repair worker's work, dots 34 are optionally projected on the entire projection plane. The damage information 33 includes damage position information 33a indicating a position of damage and a damage status 33b indicating information such as a text related to the damage. The size, pitch, and the like of the dots 34 are arbitrarily set.

  The repair location and the damage status are created using the program stored in the terminal device 40 which has acquired the image data, the information on the damage location and the type of damage from the returnable container inspection system 20. The damage information 33 is not limited to the damage position information 33a and the damage status 33b in the illustrated example, but may include various information for facilitating the repair. Based on the damage information 33, the returnable container repair assistance system 30 presents the repair person with the repair location.

  The two optical projection devices 32 a and 32 b are connected to the management device 10 and the terminal device 40. The person in charge of repair acquires the information of the container to be repaired from the management database 60 through the management device 10 by the operation of the terminal device 40. Then, the person in charge of repair transmits the damage information 33 to the optical projection devices 32 a and 32 b disposed at locations separated from each other from the terminal device 40. The optical projection devices 32a and 32b combine the received damage information 33 and the dots 34 set as necessary on the surface to be repaired of the container 27 and project the same. At this time, adjustment of the projection position is facilitated by registering in advance the dimensions of the container 27 and the reference point of the projection position. Then, the repair person repairs the recess 28 while looking at the damage information 33 and the dot 34.

  The person in charge of repair can access the management device 10 near the container 27 via the terminal device 40 and can control each device of the returnable container repair assistance system 30 at hand.

  By using the plurality of optical projection devices 32a and 32b as shown, it is possible to display the breakage information 33 by any one of the optical projection devices 32a and 32b even if the repair person is in a position to block any projection. It is possible. There is no limitation on the damage position of the container 27 and the angle at which the optical projection devices 32a and 32b project the damage state, and it is possible to project by the upper, lower, left, or right or a combination thereof. By using the optical projectors 32a and 32b capable of wide angle projection, the optical projectors 32a and 32b can be installed near the container 27. This makes it possible to reduce the work space.

  Next, with reference to FIGS. 7-11, the flow of operation of the returnable container which uses the returnable container operating system 100 is demonstrated. In addition, what is described only as a "container" in the following description and flowcharts refers to a returnable container. In the following description, the returnable container is assumed to be the container 27 shown in FIG. In addition, a program for use by each person in charge is prepared in the terminal device 40, and a menu corresponding to the operation of FIGS. 7 to 11 is selected to work.

  First, normal operation processing will be described with reference to FIG. First, the manager in charge purchases a new container, and inserts the container into the returnable container operation system 100 (step S110). The container may be any of the same type as the returnable container already in use and a container of different specifications. At the start of use of a new container, the administrator assigns the management number 61 of FIG. 3 that can be uniquely identified for each container.

  Subsequently, the manager operates the terminal device 40 to input the container basic information 60a of FIG. 3 for a new container. The management device 10 that has received the container basic information 60 a via the terminal device 40 registers the container basic information 60 a in the management database 60 of the storage unit 12. The container basic information 60a registered before the start of use is, for example, the management number 61, the container type 62, the insertion start date 63, the purchase cost 64, the size 65, the weight 66, the material 67, the loading method 68, the number of stacks 69 is there.

  Subsequently, the loaded container is inspected before the start of use (step S120). In step S120, the inspector performs inspection on the container according to the normal routine. Thereafter, the inspector inputs the record of the inspection of the container to the terminal device 40. The record of the inspection of the container is registered in the inspection history 73 of the management database 60 via the terminal device 40 and the management device 10.

  If breakage of the container is found (Step S120: Yes), the inspector in charge inputs the broken part and the breakage state to the terminal device 40 in addition to the record of the inspection of the container. The management device 10 registers the inspection record of the container, the damaged part and the damaged state in the management database 60 via the terminal device 40. The record of the examination is registered in the examination history 73. The damage location and the damage status are registered in the damage history 72. Then, it progresses to the test | inspection by the container test | inspection system of FIG.

  If no damage is found in the container (step S120: No), the use of the container is started (step S130). In step S130, the person in charge of management operates the terminal device 40 to input, for example, the articles to be transported by the container, the date of start of use, the date of planned end of use, the destination of transport, etc. The management apparatus 10 registers in the management database 60 of the storage unit 12 the articles to be transported by the input container, the use start date, the scheduled use end date, the destination of transport, and the like. The articles transported by the container are registered in the transportation history 71, and the use start date, the planned use end date, and the destination of transportation are registered in the usage history 75.

  After that, while using the container, the inspector performs inspection of the container as needed (step S140). When breakage of the container is found in the inspection in step S140 (step S140: Yes), the person in charge of inspection operates the terminal device 40 to transmit the recording of the inspection of the container, the broken part and the broken state to the management device 10. Do. The management device 10 registers the received information in the management database 60. Then, it progresses to the test | inspection by the container test | inspection system of FIG.

  When there is no breakage of the container (Step S140: No), the management device 10 receives the record of the inspection of the container via the terminal device 40, and registers it in the management database 60. Thereafter, use of the container is continued until the process set for the container is completed. The registration in the management database 60 is the same as in step S120.

  When use of the container is finished (step S150), the container is inspected after use (step S160). In step S160, the person in charge inspects the container according to the normal routine. In step S160, the person in charge operates the terminal device 40, as in step S120 and step S140, and records the inspection of the container and, if necessary, inputs information such as a broken part and a broken condition, and the management device 10 Send to The management device 10 registers these pieces of information in the management database 60.

  When the breakage of the container is found (step S160: Yes), the management device 10 receives the record of the inspection of the container, the broken part and the broken condition through the terminal device 40, and registers it in the management database 60. Then, it progresses to the test | inspection by the container test | inspection system of FIG.

  When there is no breakage of the container (step S160: No), the management device 10 receives the record of the inspection of the container via the terminal device 40, and registers it in the management database 60. Thereafter, use of the container is continued until the process set for the container is completed. The registration in the management database 60 is the same as in steps S120 and S140.

  Subsequently, the management device 10 determines whether the container needs to be re-inspected (step S170). Containers requiring re-inspection are containers that have not been found damaged but have not been inspected for a certain period since the previous inspection, or containers that have exceeded the number of uses set for each distribution route and means of transport at that time, etc. is there.

  The management apparatus 10 collates the inspection history 73 and the usage history 75 of the management database 60 based on the management number 61, and determines whether re-inspection is necessary. If it is determined that re-examination is necessary (step S170: Yes), the process proceeds to the inspection by the container inspection system of FIG. If it is determined that re-examination is not necessary (Step S170: No), the container is returned to the storage location (Step S180).

  When the container is returned to the storage location, the management person inputs the information on the container transport location, the use end date, and the storage location in the terminal device 40. The management device 10 registers in the management database 60 of the storage unit 12 the transport location, end date of use, and storage location of the container input through the terminal device 40. The transportation location is registered in the transportation history 71 of the management database 60. The use end date is registered in the use history 75 of the management database 60. The storage location is registered in the location history 76 of the management database 60.

  The containers stored in the storage location are returned to step S120, inspected before use in the next cycle, and used for normal operation.

  Next, inspection using the container inspection system 20 will be described with reference to FIG. If the manager in charge of the inspection by the container inspection system 20 determines that the inspection by the container inspection system 20 is necessary in any of steps S120, S140, S160, and S170, the administrator in charge operates the terminal device 40 to perform a menu for inspection by the container inspection system. And enter the management number 61 of the container.

  The terminal device 40 transmits the management number 61 to the management device 10. Using the management number 61 as a key, the management apparatus 10 acquires container information related to the container, that is, information such as the container type 62, the size 65, the weight 66, and the material 67 in the container basic information 60a.

  Based on the acquired container information, the supplier selection unit 11 c of the control unit 11 of the management device 10 extracts a supplier capable of inspecting the container from the inspection supplier 81 of the management database 60 and displays the container on the terminal device 40. It is presented to the person in charge (step S210). The inspection company 81 has registered in-house business establishments or other companies that have introduced the returnable container inspection system 20.

  The administrator selects the inspection inspector in charge of the inspection from the presented suppliers, and arranges the delivery of the inspection (step S220). Then, when the delivery arrangement is completed, the container to be inspected is distributed to the inspection company in charge (step S230).

  After receiving the container to be inspected, the inspection company in charge performs inspection using the returnable container inspection system 20 shown in FIG. 5 (step S240) (step S250).

  As mentioned above, the imaging device 22 images the six outer surfaces of the container. The damaged part recognition device 23 analyzes the captured image and, for example, obtains a part where the feature data matches any of the images of the damaged part stored in advance, thereby the surface including the damaged part is included in the surface Identify the coordinates of the damaged area. The damage type determination device 24 further determines the type of damage such as a hole.

  When the breakage of the container is found (Step S250: Yes), the breakage location recognition device 23 and the damage type discrimination device 24 transmit the determination result, that is, the inspection record, the breakage location and the breakage status to the management device 10. The management apparatus 10 registers the record of the inspection of the container, the damaged part and the damaged state in the management database 60 in association with the management number of the container. The record of the examination is registered in the examination history 73. The damage location and the damage status are registered in the damage history 72. Thereafter, the process proceeds to the repair of FIG.

  If no damage is found in the container (Step S250: No), the inspector in charge inputs a record of inspection of the container to the terminal device 40. The management device 10 registers the record of the inspection of the container in the inspection history 73 of the management database 60 via the terminal device 40. Thereafter, the inspection company in charge returns the container (step S260).

  After the container is returned, the administrator stores the container in a storage location. The manager also inputs the storage location of the container to the terminal device 40. The management device 10 registers the storage location of the container in the location history 76 of the management database 60 via the terminal device 40. The stored containers are returned to step S120 of FIG. 7 and inspected before use in the next cycle and used for normal operation.

  Next, the process of repair will be described with reference to FIG. If breakage of the container is found as a result of the inspection by the container inspection system, the administrator determines whether or not the container should be repaired from the breakage state (step S310). The container may be at an inspector or at a repairer in determining whether the container should be repaired.

  If it is judged that the container should not be repaired, that is, it is impossible or uneconomical to repair and reuse the container (Step S310: No), the container is discarded. This determination is determined, for example, by whether the damage is larger than the reference. The person in charge of management inputs disposal information such as disposal date and disposal method to the terminal device 40. The terminal device 40 registers the discarding information in the usage history 75 of the management database 60 of the storage unit 12 via the management device 10.

  If it is determined that the container should be repaired (Step S310: Yes), an image instructing repair of the container is displayed on the terminal device 40. The administrator selects a menu for repair by the container inspection system in the terminal device 40, and inputs the management number 61 of the container.

  The terminal device 40 transmits the management number 61 to the management device 10. The management apparatus 10 refers to the management number 61 to the management database 60, and acquires necessary information such as the container type 62, the size 65, the weight 66, and the material 67 in the container basic information 60a.

  The trader selection unit 11c of the control unit 11 of the management device 10 extracts a repairable trader from the repair trader 82 of the management database 60 based on the acquired container basic information 60a and displays it on the terminal device 40. Presented to the person (step S320). As the repairer 82, a company's own business establishment or other contractor who has introduced the returnable container repair assistance system 30 is registered.

  The administrator selects a responsible repairer who requests an inspection from the presented supplier, and arranges the delivery of the inspection (step S330). Then, when the delivery arrangement is completed, the container to be repaired is delivered to the responsible repairer (step S340).

  After receiving the container to be repaired, the responsible repairer performs repair using the returnable container repair assistance system 30 shown in FIG. 6 (step S350).

  At this time, in order to facilitate repair, the terminal device 40 reads the latest damage information corresponding to the management number of the container from the management database 60, and the optical projection devices 32a and 32b damage the damaged area and the damaged area. Project to the vicinity of the damage point of the surface including. Furthermore, an image of a damaged part may be extracted from an image obtained at the time of inspection and the processed image may be projected by coloring the image.

  At this time, an imaging device is disposed in the optical projection devices 32a and 32b, and it is determined which surface is currently opposed, and further, the size of the surface to be projected and the inclination with respect to the surface are determined. It is desirable to go and project to the appropriate position.

  After completion of the repair, the repair person inputs the repair record of the container into the terminal device 40. The terminal device 40 registers the input repair record of the container in the repair history 74 of the management database 60 of the storage unit 12 via the management device 10. Thereafter, the responsible repairer returns the container (step S360).

  After the container is returned, the administrator stores the container in a storage location. The manager also inputs the storage location of the container to the terminal device 40. The management device 10 registers the storage location of the container in the location history 76 of the management database 60 via the terminal device 40. The stored containers are returned to step S120 of FIG. 7 and inspected before use in the next cycle and used for normal operation.

  Next, quantity management of containers will be described with reference to FIG. By the normal operation of FIG. 7, the inspection of FIG. 8, and the repair of FIG. Therefore, in order to prevent shortage of containers, it is preferable to manage the quantity.

  As shown in FIG. 10, for example, the management apparatus 10 periodically refers to the management database 60 (step S410). The data to be referred to are, for example, inspection history 73, repair history 74, use history 75, and location history 76. The number management unit 11d of the control unit 11 of the management device 10 determines the number of containers before and after use, the scheduled return date of the containers in use, the scheduled inspection completion date of the containers under inspection, The planned date of repair completion of containers under repair, the number of wastes, etc. are counted. Also, refer to future shipping schedule.

  Subsequently, the quantity management unit 11d obtains the number of containers to be in stock for each type and the expected period, such as two weeks, on a daily basis, from the collected data. The quantity management unit 11d determines whether there is a day when the determined number of stocks becomes equal to or less than the threshold (step S420). The types of containers are grouped, for example, for the same container type 62, size 65, weight 66, and material 67.

  If it is not determined that the container inventory is less than or equal to the threshold (step S420: No), the process returns to step S410. Thereafter, the management device 10 continues to refer to the management database 60 each time a predetermined period has elapsed.

  If it is determined that the inventory of the containers is equal to or less than the threshold (step S420: Yes), the quantity management unit 11d finds the number required to reach the threshold and proposes that the number of containers be replenished (step S430). ). The proposal is performed by, for example, displaying on the display unit 44 of the terminal device 40 as an alarm. The process then returns to step S410 and continues referring to the management database 60 at regular intervals. The person in charge refills the container as necessary in consideration of the proposal of the quantity management unit 11d.

  Next, container design support will be described with reference to FIG.
