Description

  The present invention relates to an article management system and an article management method for managing articles based on brought-in article information of articles brought into a management area and brought-out article information of articles taken out.

  For example, in a facility such as a power plant, necessary tools and measuring instruments are brought into the facility when performing periodic inspections, repairs, and repairs. If the article brought in is misplaced in the facility after the work is completed, the remaining article may affect the operation of the facility. Therefore, it is necessary to manage the articles brought into the facility so that they are not left behind.

  Conventionally, in order to prevent such misplacement, an operator has entered information on items to be brought in and items to be taken out into the management ledger. However, it takes time to fill out the information of all articles in the management ledger, and the management of the articles in the facility is not sufficient, such as omission of entry or confirmation omission.

  Therefore, a management system for managing articles by storing information on articles to be brought in and collating with stored article information at the time of taking out has been proposed (Patent Document 1). Specifically, the image information (image data) obtained by photographing the article to be brought in and the weight information (weight data) obtained by measuring the weight are stored in the storage means. By searching stored information based on image information and weight information, the brought-in article is specified and displayed, and the article is managed. At this time, the worker compares the displayed image of the article with the actual article and confirms that they are the same article. Patent Document 1 also describes that the collation at the time of taking out is ensured by giving an identification number to the article.

Japanese Patent No. 495656

  However, in the method of specifying the target article based on the weight information as described in Patent Document 1, when different articles are taken out even with the same weight, a plurality of articles are displayed as a result of retrieval during takeout. It is expected that In that case, it is necessary to select and confirm the target article from the displayed images of the plurality of articles. For this reason, there is a problem that it takes time and effort to confirm the article at the time of taking out, and the efficiency is not good.

  Moreover, in the method of managing by giving an identification number to an article described in Patent Document 1, the identification number is stored in an IC tag and attached to the target article. As a result, at the time of bringing in and taking out articles, it is possible to perform management only by reading the information of the IC tag attached to each article. However, articles to be brought in include metal objects, waste (cloth), wire numbers (wires), and the like, and it may be difficult to attach the IC tag. In addition, when an IC tag is attached to a tool, the IC tag may deteriorate due to use of the tool, resulting in a reading error, or the attached IC tag may be peeled off, resulting in a new leftover. . Further, the IC tag used by being attached to a metal needs to use a high-performance expensive tag in order to ensure reading performance, and there is a problem that the capital investment cost increases.

  Therefore, in view of the above circumstances, the present invention reliably and efficiently manages brought-in and taken-out articles without using an IC tag, and generates new leftovers due to IC tag peeling or the like. An object of the present invention is to provide an article management system and an article management method that are free of concerns.

  An article management system according to the present invention for solving the above-mentioned problems is an article management system for managing articles based on article information brought into a management area and article information of articles to be taken out, and conveying means for conveying articles , Shape information acquiring means for acquiring shape information of an article, input means for inputting input information including at least the article name of the article and worker information, and storage means for storing the shape information and input information of the article as article information The shape information of the article and the name of the article are stored in advance in the storage means as pre-registration information, and when the article is brought into or taken out from the management area, it is based on the acquired shape information and the shape information. The article name of the article specified by searching the storage means and the worker information are stored in the storage means as brought-in article information or taken-out article information, and the brought-in article information and the carried-out article information are stored. By compare, it is characterized in that managing the articles goods and brought brought into the controlled area.

  According to such a configuration, it is possible to acquire information on a conveyed article, and therefore it is possible to acquire information continuously for a plurality of articles. In that case, necessary information can be easily acquired by the shape information acquisition means and the input means. By storing these pieces of information in the storage means, the corresponding article can be specified by the search.

  In addition, by performing pre-registration, information on articles to be brought into the management area can be stored in advance in the storage means. Thereby, the labor of registration at the time of carrying in can be simplified. At that time, the names of the articles can be unified by registering the article names.

  When the article is brought in, by acquiring the shape information, it is possible to specify the article by searching the pre-registration information stored in the storage device based on the shape information. And the double registration by giving a different name with respect to the same goods can be prevented by making the goods name of the specified goods into one of brought-in goods information. In addition, by inputting worker information, it is possible to manage brought-in articles in units of workers.

  On the other hand, at the time of taking out the article, the article can be identified by searching the storage device based on the acquired shape information, as in the case of bringing in the article. In addition, the search in this case may search pre-registration information, and may search carry-in article information. In this manner, the article name of the identified article is set as one item of carry-out article information in the same manner as when bringing it in. Further, by inputting the worker information, it is possible to reliably identify the article at the time of take-out.

  By storing the brought-in article information and the brought-out article information created in this manner in the storage means, the article can be easily managed. Further, by comparing the stored brought-in article information with the taken-out article information, it is possible to reliably confirm whether or not all the articles brought into the management area have been taken out. That is, if all the brought-in article information and the brought-out article information match, it can be confirmed that there are no leftovers in the management area. Furthermore, since an identification number is not used and there is no need to attach an IC tag, it is possible to prevent generation of new leftovers due to peeling of the IC tag or the like.

  Further, in addition to the above configuration, the article management system of the present invention further includes weight measuring means for measuring the weight of the conveyed article to obtain weight information, and the article information stored in the storage means includes the weight Information, the shape information of the article, the article name, and the weight information are stored in advance in the storage means as pre-registration information, and when the article is brought into or taken out from the management area, the obtained shape information and weight The article name of the article specified by searching the storage means based on the information, the shape information and the weight information, and the worker information are stored in the storage means as brought-in article information or brought-out article information, and the brought-in article It is preferable to manage the articles brought into the management area and the articles taken out by comparing the information with the carried-out article information.

  Thereby, since the article information includes the weight information of the article, the article can be identified more reliably. Specifically, the weight does not change even when the shape information is acquired in different shapes at the time of carry-out and take-out, such as an article whose shape is deformed (for example, pliers, pliers, etc.) By using the weight information in addition to the shape information, it is possible to more reliably identify the article at the time of take-out.

  The shape information acquisition means in the article management system of the present invention includes a laser light irradiation means for irradiating the article with laser light, an imaging means for imaging the laser light irradiated on the article, and the target information from the imaging information. You may provide the calculating means which calculates | requires dimension information. Thereby, since shape information can be acquired as, for example, three dimension information (length dimension, width dimension, and thickness dimension) from the imaging information, it is possible to reliably identify the target article.

  By the way, it is preferable to manage the articles brought into the management area in association with the workers in units of workers. However, for example, the work is often performed by a plurality of workers of a company that undertakes the work, and the articles are held. There is a case where the worker to be brought in and the worker to be brought out do not necessarily match. In such a case, since the worker information at the time of taking out the articles is different, the carried-in article information and the carried-out article information do not match, which takes time and effort for confirmation.

  Therefore, it is preferable that the worker information has a worker name and company information. Thereby, since it has common company information as worker information of a plurality of workers, a plurality of workers can be managed as a group. For this reason, even when another worker of the same company takes out an item brought by a certain worker, it can be managed easily and reliably.

  Here, depending on the facility, a plurality of management areas may be set. In that case, it is necessary to perform pre-registration for each management area, and the same article may be pre-registered a plurality of times, so registration takes time. For this reason, the articles brought into a plurality of management areas and the article information of the articles to be taken out may be stored in the storage means as initial registration information. As a result, even if the facility has a plurality of management areas, it is only necessary to select necessary article information from the initial registration information in each management area, thus simplifying the registration of pre-registration information. It becomes possible.

  Moreover, you may acquire the time information of the time when the goods were brought in, or the time when the goods were taken out as carry-in article information or carry-out article information. Thereby, the article at the time of take-out can be more reliably identified by referring to the time information.

  Further, the number information indicating the number of articles may be input from the input means as the brought-in article information or the brought-out article information. As a result, when multiple items of the same type are brought in, the weight information and shape information can be acquired for one of them, and the item information can be created by inputting the number information. Compared to creating the article information, it is possible to significantly reduce the time required for creating the article information.

  On the other hand, the article management method of the present invention is an article management method for managing an article based on the article brought into the management area and the article information of the article to be taken out, the conveying means for conveying the article, and the article to be conveyed A weight measuring means for measuring the weight of the article to obtain weight information, a shape information obtaining means for obtaining the shape information of the article, an input means for inputting input information including at least the article name of the article and worker information, Storage means for storing article weight information, shape information, and input information as article information. The article weight information, shape information, and article name are stored in advance in the storage means as pre-registration information, and the article is stored in the management area. When the user is brought in or taken out, the obtained weight information and shape information, the article name of the article specified by searching the storage means based on the weight information and the shape information, and the worker information are held. Included It is stored in the storage means as article information or taken-out article information, and the articles brought into the management area and the articles taken out are managed by comparing the brought-in article information with the brought-out article information. .

  Using this method, in the same manner as described above, by comparing the stored carry-in article information with the carry-out article information, it is surely confirmed whether or not all the articles brought into the management area have been taken out. Can do.

  As described above, according to the present invention, it is possible to manage articles that are brought in and out reliably and efficiently without using an IC tag, and there is a concern that new leftovers may be generated due to peeling of the IC tag or the like. An article management system and an article management method can be provided.

  The positional relationship between the laser light source unit 226 and the 3D camera 227 is shown in FIG. The laser light source unit 226 is disposed downward so as to irradiate the article M to be conveyed with a line-shaped laser beam downward. In addition, the 3D camera 227 is arranged on the downstream side in the transport direction from the laser light source unit 226 so as to capture the irradiated laser light from an oblique direction.

  As shown in FIG. 1, the discharge unit 23 is provided adjacent to the discharge side of the shape information acquisition unit 22 and includes a plurality of conveyance rollers 231. Each transport roller 231 is driven by a drive mechanism (not shown). Further, the transport roller 231 is disposed at the same height as the transport surface by the transport roller 211 and the transport conveyor 221 of the weight measuring unit 21.

  The article carry-out unit 30 includes an article take-out stand 31 as a work table for taking out the article M from the tray 13, and a plurality of trays 13 from which the article M has been taken out are placed on the stand. The tray 13 placed on the article take-out table 31 is appropriately moved to the article placement table 11 of the article carry-in unit 10.

  FIG. 2 shows a block diagram of a control system of the article management system 1 according to the present invention.

  In the present embodiment, various controls are performed in the computer 40 as a control means provided in the housing 223. As shown in FIG. 2, the computer 40 is equipped with a CPU 41 including a control device 41a and an arithmetic device 41b, a memory 42 for temporarily storing various information, a clock function (not shown), and the like.

  The computer 40 is connected to various devices that input / output various information through an I / O port (not shown). Specifically, the bar code reader 12, the weighing device 213, the 3D camera 227, the photographing camera 228, the input device 51 (display panel 50), and the like are connected as information input devices. On the other hand, an alarm device 229, a laser light source unit 226, a conveyance roller 211, a driving roller 224, a display device 52 (display panel 50), and the like are connected as information output devices. In addition, an information capturing unit 43 for capturing various information and an information output unit 44 for outputting are provided. Further, the computer 40 is connected to a storage device 60 in which pre-registration information 61, brought-in article information 62, brought-out article information 63, etc., which will be described later, are stored.

  Here, the display panel 50 which is a touch panel is demonstrated based on FIG. The display panel 50 displays image information and character information stored in the memory 42 and the storage device 60 of the computer 40. As an example of the display on the display panel 50, FIG. Specifically, as the image information, an image photographed by the photographing camera 228 and an image stored as pre-registration information are displayed. As the character information, information indicating processing contents, acquired article information, information stored as pre-registration information, and the like are displayed. The quantity setting button and the correction button shown in the figure function as the input device 51. By pressing these buttons, a quantity setting screen or a correction screen (not shown) is separately displayed, and various information can be input as appropriate.

  Next, a management method for the article M in the target management area using the article management system 1 according to the present embodiment will be described. The article management system 1 stores the article information of the article M to be brought in, and confirms whether there is no leftover in the management area by comparing the article information when the article M is taken out. is there. Prior to the process of bringing in the article M, information on the article to be brought in is registered in advance (pre-registration process). The pre-registration process proceeds according to the display on the display panel 50 of the article management system 1.

  FIG. 5 shows a flowchart of the pre-registration process. First, a target management area for managing the article M is set (S101). Next, company information and worker name information as worker information are registered (S102, S103). The company information and the worker name information may be their names or names, or may be symbols or numbers. The worker information may be input from the input device 51, or information such as a list created separately may be acquired from the information acquisition unit 43 (see FIG. 2).

  Subsequently, the article management system 1 shown in FIG. 1 acquires article information of each target article M to be registered as advance information. Acquisition of article information is started by placing the target article M on the tray 13, setting it on the transport roller 211, and pressing a start button (not shown) shown on the display panel 50 of the housing 223. .

  In the article management system 1, first, the weight of the target article M is measured by the weight measuring unit 21 (S104). Specifically, when the tray 13 is transported to a predetermined position, the transport roller 211 is stopped, and the lifting platform 214 a is lifted by driving the lifting device 214. As the elevator 214 a rises, the support member 212 also rises, and the convex portion 212 a protrudes from between the conveying rollers 211 and comes into contact with the bottom of the tray 13. The tray 13 is separated from the conveyance roller 211 and supported by the support member 212. When the elevator 214a rises to a predetermined height, the elevator 214 stops and the weight is measured by the weighing device 213. When the weight measurement is completed, the lifting device 214 is driven again, and the lifting platform 214a is lowered to the initial position. As a result, the support by the support member 212 is released, and the tray 13 is supported by the transport roller 211. The weight information obtained by the measurement includes not only the weight of the target article M but also the weights of the support member 212 and the tray 13. Weight information other than the target article M is separately measured and stored in advance. By removing from the measured weight information, the weight information of only the target article M can be acquired.

  Further, the image information of the target article M is acquired by the photographing camera 228 during the weight measurement (S105). The acquired image information of the target article M is stored in the memory 42 of the computer 40. The image information may be displayed on the display panel 50.

  Next, the tray 13 is transported toward the housing 223 of the shape information acquisition unit 22 by driving the transport roller 211 and the transport conveyor 221. When the tray 13 reaches the passage part 222 inside the housing 223, the laser light source part 226 is activated to irradiate the target article M with laser light and to image the laser light emitted by the 3D camera 227 (FIG. 3). reference). Specifically, the target article M is conveyed in a state where the laser light source unit 226 irradiates the line-shaped laser light downward, and the 3D camera 227 images the irradiation region of the laser light from an oblique direction. At this time, since the line-shaped laser light irradiated on the target article M is reflected on the surface of the article M, it is generated in correspondence with the three-dimensional shape of the target article M by imaging from the oblique direction with the 3D camera 227. A step can be clearly imaged (see FIG. 3). In this way, imaging by the 3D camera 227 is continued until the tray 13 is conveyed to a predetermined position, and the three-dimensional image information of the target article M can be acquired as imaging information.

  Here, in the present embodiment, dimensional information (length dimension, width dimension, thickness dimension) as the shape information of the target article M is calculated and obtained based on the acquired three-dimensional image information (S106). Such dimensional information is obtained by analyzing an image of the acquired three-dimensional image information. Specifically, as shown in FIG. 6, a rectangle circumscribing the article is created in a state viewed from above and from the side, and a virtual frame circumscribing the article is set. The dimensions of the virtual frame in the X-axis direction, the Y-axis direction, and the Z-axis direction are obtained, and the length, width, and thickness are set in descending order of the numerical values. This calculation is performed by the calculation device 41b of the computer 40.

  Subsequently, the name of the target article M is input (S107) (see FIG. 5). In the present embodiment, the name of the article is input from the input device 51 of the display panel 50 that is a touch panel (see FIG. 4).

  When the article information is acquired in this way, the storage device 60 (see FIG. 2) is searched to check whether the same information has already been registered (S108). If the same information is not registered as a result of the search (S108: N), it is registered as article information (S109). The registration is stored in the storage area of the pre-registration information 61 of the storage device 60 (see FIG. 2). On the other hand, if the same information is registered as a result of the search (S108: Y), since the target article M has already been registered as the pre-registration information 61, registration is unnecessary (S110).

  When the acquisition of the shape information of the target article M is completed in the article management system 1, the tray 13 is transported to the transport roller 231 of the discharge unit 23 by the transport conveyor 221. Thereafter, the tray 13 is moved from the discharge unit 23 to the article take-out stand 31 of the article carry-out unit 30, where the target article M is taken out from the tray 13.

  Further, if there is another article M to be pre-registered (S111: present), the target article M is placed on the tray 13 and the article information is similarly acquired. A plurality of articles M may be placed on the tray 13 and the article information may be acquired sequentially. On the other hand, if there is no other article to be pre-registered (S111: None), the pre-registration process is terminated. In this way, information on the article M used in the target management area can be registered in advance. In addition, when the target article M has a size that cannot pass through the housing 223, only the image information acquired by photographing with the photographing camera 228 may be stored. Further, the dimension information may be input from the input device 51.

  Next, an article bringing process when the article M is brought into the management area by the worker will be described. FIG. 7 shows a flowchart of the article bringing process. The worker brings the article M to be brought into the management area, and performs the bringing-in process of the article M by the article management system 1 shown in FIG.

  First, the target management area is set (S201). This confirms that the work place is the target area.

  Next, the worker reads the worker information recorded on the attached ID card with the barcode reader 12. In the present embodiment, company information and worker name information are written in a two-dimensional barcode (QR code: registered trademark) on the ID card, and the company information and work are read by the barcode reader 12. The person name information can be acquired at the same time (S202, S203). The company information and the worker name information may be written separately or may be displayed as a one-dimensional barcode.

  Subsequently, “carry-in process” is selected from “carry-in process / carry-out process” displayed on the display panel 50 (S204). Since the operation for acquiring the article information is the same for bringing in and taking out, which processing is set here.

  Further, the article information of the brought-in article M is acquired from 1 by the article management system. For the article information, the article management system 1 acquires weight information (S205) of the brought-in article M, image information (S206) by the photographing camera 228, and shape information (S207). In addition, since acquisition of article information is the same as the operation of the above-described pre-registration process, detailed description is omitted.

  Here, based on the acquired article information, the pre-registration information 61 stored in the storage device 60 is searched to confirm whether or not the information of the brought-in article M is pre-registered (S208). If it is a pre-registered article M (S208: Yes), it is confirmed whether the name of the article M matches the name of the brought-in article M (S209). Specifically, the name of the article M is confirmed by the operator by displaying the name of the article M as a search result on the display panel 50. The display panel 50 may display the shape information and image information of the article M together. Further, when a plurality of articles M are candidates as a result of the search, information on the plurality of articles M may be displayed and selected. Here, when searching for the article M, it is determined that the same article M is obtained when three or more of the four pieces of article information of the weight information, the length dimension, the width dimension, and the thickness dimension match.

  On the other hand, when the carry-in article M is not pre-registered (S208: None), and when it is pre-registered, the name is different (S209: N), the name of the carry-in article M from the display panel 50. Is input (S210). In addition, even if it is the same goods M, when names are different (for example, a monkey wrench and a monkey spanner), it is judged that they are the same goods M by confirming the shape of the goods M displayed on the display panel 50. Thereby, it is possible to prevent the same article M from being registered with a plurality of different names.

  In this way, when the name of the brought-in article M is entered, or when the name of the brought-in article M is confirmed as in the case where the name of the brought-in article M matches the name of the article M registered in advance (S209: Y), Subsequently, the quantity of the brought-in article M is input (S211). When bringing a plurality of articles M of the same type, if the carry-in process is performed one by one, the same work is repeated, which takes time and effort. Therefore, about the goods of the same kind, a carrying-in process is performed about one of them, and a process can be simplified by inputting quantity. Moreover, at the time of taking out, it can be confirmed whether there is no leftover by confirming whether or not the same number of target articles M have been taken out.

  Thereafter, the brought-in time is acquired as time information from a clock function (not shown) (S212), and these pieces of information are stored in the storage device 60 as brought-in article information 62 (S213). Note that the time information acquired from the clock function may include not only time but also date information.

  Furthermore, if there is another carry-in article M that carries out carry-in processing (S214: Yes), the article information is similarly acquired. If there is no other brought-in article M to be brought in (S214: No), the article brought-in process is terminated. In this manner, the information on the article M brought into the target management area can be stored in the storage device 60 as the brought-in article information 62. In the present embodiment, the carry-in article information 62 is stored in units of workers.

  On the other hand, FIG. 8 shows a flowchart of the article take-out process. When the worker finishes the work in the management area and takes out the article M, the article management system 1 shown in FIG. The process proceeds according to the display on the display panel 50 as in the article bringing process. Since the setting from the target management area (S301) to the acquisition of shape information (S307) is the same as the article bringing-in process, detailed description thereof is omitted. In step S304, unlike the item bringing-in process, “take-out process” is selected.

  When the shape information of the article M is acquired, the quantity of the brought-out article M is subsequently input (S308). Thereafter, the take-out time is acquired from a clock function (not shown) (S309). In this way, various article information regarding the brought-out article M is acquired.

  Based on the article information acquired in this way, the brought-in article information 62 stored in the storage device 60 is searched to check whether the information on the brought-out article M is stored as the brought-in article M. (S310). If it is not stored as a carry-in article M (S310: None), it is confirmed whether or not continuous use information (details will be described later) is added as a continuous use article (S311). If the continuous use information is not added (S311: None), it is stored as an unmanaged article (S312). In addition, since there is a possibility that the unmanaged article may be an article brought in by another worker, it is preferable to store the unmanaged item without dividing it by worker.

  On the other hand, when it is stored as the brought-in article M (S310: yes) or when the continuous use information is memorized (S311: yes), it is stored in the storage device 60 as the carried-out article information 63 (S313). ). In the present embodiment, the carry-out article information 63 is stored in units of workers similarly to the carry-in article information 62.

  After storing the information of the carry-out article M in this way, if there is another carry-out article M (S314: Yes), the article information is similarly acquired, and the carry-in article information 62 is searched for confirmation. Do. Note that in the article take-out process, the article name of the article M is not changed when it is brought in. Therefore, when matching is performed by collation, the article name of the brought-in article information 62 is used as it is.

  On the other hand, if there is no other carry-in article M (S314: None), the carry-in article information 62 and the carry-out article information 63 by the worker are compared (S315). As a result of the comparison, if there is an article M that is stored as brought-in article information 62 but is not stored as taken-out article information 63, the article M is a remaining article that remains in the target management area. . In this way, the presence or absence of a remaining article is confirmed (S316). If there is a remaining article (S316: Y), it is determined whether or not the article M is to be used continuously (S317). If it is used continuously (S317: Y), information (continuous use information) as a continuously used article is added to the brought-in article information (S318). Note that examples of continuously using the article M include a case where it is installed as a scaffold for work and a case where the work is carried out over a plurality of days and is not intentionally taken out.

  If it is the remaining article M but is not used continuously (S317: N), the article information is stored in the storage device 60 as an unknown article (S319). In addition, since there is a possibility that the unidentified article may have been taken out by another worker by mistake, it is preferable to store the article without being classified by worker. When an unidentified article is taken out by another worker, it is stored as an unmanaged article, so it is preferable to compare the article with the unmanaged article. This may identify the location.

  In this way, if the article M can be confirmed by comparing the brought-in article information 62 and the brought-out article information 63, the article taking-out process is terminated. Thereby, the article M brought into the target management area and the article M taken out can be reliably managed.

  In the present embodiment, the weight measuring unit 21 is not necessarily an essential configuration, and may be the article management system 1 that does not include the weight measuring unit 21. In this case, as the article information of the article M, it is preferable to obtain shape information other than the length dimension, width dimension, and thickness dimension information from the three-dimensional image information acquired by the shape information acquisition unit 22. Thereby, the article M can be specified without using the weight information.

  Here, as the shape information obtained from the three-dimensional image information, in addition to the above-described dimension information (length dimension, width dimension, thickness dimension information), for example, area, center of gravity height dimension, peripheral height dimension, peripheral length Dimensions can be used. As for the area, the area of the upper surface of the article may be obtained. The height of the center of gravity is the height in the vertical direction (Z-axis direction in FIG. 6) passing through the center of gravity. The center of gravity can be obtained from the coordinates of the center of gravity position by using a well-known method from the value of the coordinates of the pixel in which the article exists and the number of pixels in each of the X coordinate and the Y coordinate on the X axis Y axis plane of FIG. it can. Moreover, the maximum value or average value of the height along the outer periphery of the article can be used as the peripheral height. Thus, since various information can be acquired and used as the shape information from the three-dimensional image information, the article M can be reliably identified without using the weight information. Can be managed.

  In the above embodiment, when searching for and specifying the article M, the same article M is obtained when three or more pieces of the four pieces of article information of weight information, length dimension, width dimension, and thickness dimension match. However, when the weight information is not used, any four pieces of information can be used from various pieces of shape information including the dimension information. Of course, shape information other than the above-described length, width, and thickness dimensions and weight information may be used in combination.

  In the present embodiment, the carry-in article information 62 and the carry-out article information 63 are stored in the storage device 60 in units of workers. However, the present invention is not limited to this, and a plurality of workers are grouped. You may make it memorize | store it collectively. Specifically, the company unit to which the worker belongs is preferable. Thereby, when comparing the brought-in article information 62 and the brought-out article information 63 (S315 in FIG. 8), the comparison target can be expanded from the worker unit to the group (company) unit. Therefore, for example, when working in a management area, even if a plurality of workers work and another worker may bring the brought-in article M, another worker brings it. Since the article M is also a comparison target, the occurrence of unmanaged articles and unidentified articles can be reduced, and management can be simplified. As a result, when the article M is taken out (at the end of the work), one of the workers represents the worker information on the ID card as a representative, and the articles about all the articles M brought in are read. It is also possible to sequentially perform information acquisition processing. As a result, it is possible to save time and labor for the carry-out process.

  Further, in the present embodiment, the article M used in the target management area is registered in advance as pre-registration, but the article information of the actual article M is acquired on the spot during the pre-registration process. Therefore, when there are multiple management areas in the facility, it is necessary to pre-register in each management area even for the same type of goods M used in each management area, and the same work is performed multiple times. It takes time and effort. Therefore, for the articles M that are commonly used in different management areas, article information may be prepared in advance as initial registration information. Specifically, in the flowchart of the pre-registration process in FIG. 5, steps S104 to S111 are performed, and the acquired article information is registered as initial registration information in S109.

  When pre-registration is performed in the target management area, it is possible to save labor for registration by using the initial registration information. Also, when performing registration in another management area, the initial registration information can be used in the same manner, so that the labor of registration can be saved. Thus, it is more effective in facilities having a plurality of management areas. The initial registration information may be registered in advance in the system when, for example, the article management system 1 is installed in a management area in the facility. Alternatively, it may be stored in a storage device connected via a LAN or the like, and the initial registration information may be used by connecting to this storage device during the pre-registration process, and various storage media (eg, CD, DVD, flash memory) Etc.) and may be taken in from the storage medium each time and used. In that case, it is preferable to fetch the initial registration information from the information fetching unit 43 shown in FIG.

  Furthermore, the acquired or input article information may be changed. Specifically, it is preferable that worker information can be changed. For example, the information change is preferably performed at the same time as inputting information related to the continued use of the carry-out process (FIG. 8: S316) and from the input device 51 of the display panel 50. Thereby, for example, when the article M used when working for a plurality of days is brought in, even if the brought-in worker is changed in the middle, it is changed to the succeeding worker. Thus, when the target article M is taken out at a later date, it is searched without any problem during the article take-out process.

  By the way, in a facility that needs to manage the carry-in of the article M, the management table may be created and reported by collecting the status of the carry-in and take-out of the article M after the daily work ends. Therefore, a management table may be created based on the brought-in article information 62 and the taken-out article information 63 in the target management area. Specifically, as shown in FIG. 9, the management table 70 includes a target management area, a date and time of bringing in each article, a company ID (company information), a worker ID (worker name information), a number, and weight information. For each piece of information on the shape information (length dimension, width dimension, thickness dimension), it is preferable to display a list of information at the time of bringing in and information at the time of taking out. Thereby, since it can produce based on the information memorize | stored in the memory | storage device, the list of the information regarding the carrying-in and taking-out of the article | item M can be created easily.

  The output of the management table 70 may be printed out on a paper medium, or may be output to a portable terminal such as a notebook computer or a tablet terminal, a computer connected via a LAN, or the like. In that case, it is preferable to output from the information output part 44 shown in FIG. In FIG. 9, the management table 70 is created for each article M. However, the management table 70 is not limited to this, and may be created for each worker or company. Furthermore, the creation of the management table 70 is not limited to after completion of daily work, but may be any timing during the day, work units such as weekly or monthly, or periodic inspection.

  As described above, according to the article management system of the present invention, the article information of the article M to be brought into the target management area is registered in advance, and when the article M is brought in, the weight information and the shape information of the article M are obtained. The article M is specified by acquiring and searching the pre-registration information stored in the storage device based on the information. In that case, it is not necessary to input all information on the article M on the spot. Therefore, the article bringing process can be simplified and the time required for the process can be shortened. In addition, by using pre-registered article names, it is possible to prevent a plurality of article names from being assigned to the same article M. On the other hand, when the article M is taken out, it is the same as in the carrying-in process except that the pre-registration information or the brought-in article information stored in the storage device is searched. Further, by comparing the brought-in article information with the brought-out article information, it can be easily confirmed whether or not the brought-in article M has been taken out.

  Further, in the article management system 1, since it can be continuously performed by simply placing the article M on the tray 13, even a plurality of articles M can be brought in and taken out without delay. it can. In that case, since the information of the article M is obtained by directly measuring the article M to obtain the article information, there is no need to attach an IC tag to the article M, and it is difficult to attach an IC tag. Even so, carry-in and take-out management can be easily performed. Furthermore, since daily carry-in and take-out management can be easily performed, even if a remaining article is generated in the target management area, it can be detected early.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. The article management system and article management method according to the present invention are not limited to facilities such as a power plant, but may be used in various construction sites, roads, railroad tracks, factories, medical institutions, research facilities, and the like.

  In addition, the management is not limited to installing an article management system for each target management area, but is installed at one place, such as an entrance to a facility having a plurality of management areas, to manage the article M in the plurality of management areas. May be performed together.
