[Figure 2]Figure 2 is a diagram illustrating an example of arrival information according to the first embodiment. [Figure 3] Figure 3 is a diagram illustrating an example of a packaging apparatus 20 according to the first embodiment. [Figure 4] Figure 4 is a sequence diagram showing an example of the operation of the film roll management system 1 according to the first embodiment. [Modes for carrying out the invention]

[0011] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of dimensions, etc., may differ from those of reality. Therefore, specific dimensions, etc., should be determined by referring to the following description. Furthermore, there may be parts in the drawings where the relationships and ratios of dimensions differ from those of other parts. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustration.

[0012] (First Embodiment) The film roll management system 1 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 4. Figure 1 is a diagram showing an example of the overall configuration of the film roll management system 1 according to the first embodiment, Figure 2 is a diagram for explaining an example of incoming information according to the first embodiment, Figure 3 is a diagram for explaining an example of a packaging device 20 according to the first embodiment, and Figure 4 is a sequence diagram showing an example of the operation of the film roll management system 1 according to the first embodiment.

[0013] As shown in Figure 1, the film roll management system 1 according to this embodiment includes an acquisition unit 10, a packaging device 20, a management device 30, a label issuing device 40, and a display unit 50.

[0014] The acquisition unit 10 acquires specific information that identifies the film roll 100 from the inheritance label L1 affixed to the film roll 100. This specific information may include, in addition to the identification information of the film roll 100, the current amount of film remaining in the film roll 100, the date the film roll 100 was replaced, the type of film roll 100, and the date the film roll 100 was received.

[0015] For example, such specific information may be printed on the inheritance label L1 in the form of a one-dimensional code or a two-dimensional code. Furthermore, if the inheritance label L1 includes or is composed of an RFID chip, such specific information may be stored within the chip. The acquisition unit 10 may be composed of a scanner capable of reading the aforementioned one-dimensional or two-dimensional codes, or of a device capable of reading the data (specific information) within the aforementioned chip.

[0016] If the management device 30 determines that the specific information acquired by the acquisition unit 10 matches the product to be produced, it instructs the packaging device 20, on which the film roll 100 is mounted, to start production. Here, the acquisition unit 10 acquires specific information that identifies the film roll 100 from the inheritance label L1 attached to the film roll 100 mounted on the packaging device 20.

[0017] Furthermore, if the packaging device 20 terminates production without using up the film roll 100, it transmits the current remaining film amount of the film roll 100 to the control device. The remaining film amount in this case is disclosed, for example, in Japanese Patent Application Publication No. 2019-156591 filed by the present applicant. The control device 30 then transmits new specific information, including the current remaining film amount, to the label issuing device 40 to issue a new successor label L1.

[0018] The label issuing device 40 issues this new inherited label L1, and the issued new inherited label L1 is attached to the remaining film roll removed from the packaging device 20. For example, the label issuing device 40 may issue an inherited label L1 printed with the above-mentioned specific information, or may issue an inherited label L1 including an RFID chip storing such specific information or an inherited label L1 constituted by an RFID chip.

[0019] According to the above configuration, by using the inherited label L1 automatically issued by the label issuing device 40, the proper use and management of the film roll 100 can be thoroughly carried out.

[0020] Also, the label issuing device 40 may issue an inherited label L1 based on the incoming information of the film roll 100.

[0021] Here, the incoming information is information including, in addition to the identification information attached to the film roll 100 at the time of incoming, the manufacturing date, rod number, winding amount, etc. of the film roll 100.

[0022] Note that the inherited label L1 is attached to the incoming film roll 100. In this case, the incoming information is, as shown in FIG. 2, for example, information obtained from the label L2 of the cardboard box 200 in which the film roll 100 is housed at the time of incoming. Alternatively, the incoming information is obtained from the label attached to such a plastic bag when the film roll 100 is incoming wrapped in a plastic bag. Also, the incoming information may be stored in a chip attached to the cardboard or plastic bag.

[0023] According to such a configuration, by managing the incoming date of the film roll 100 using the incoming information L2, a first-in, first-out check and warning can be performed.

[0024] Furthermore, as shown in FIG. 1, the management device 30 may include a storage unit 31 that stores the specific information acquired by the acquisition unit 10 and the above-mentioned new specific information acquired from the packaging device 20.

[0025] If the replacement date of the film roll 100 included in the specific information acquired by the acquisition unit 10 is not the oldest replacement date stored in the storage unit 31, the management device 30 may issue a warning.

[0026] This configuration eliminates the problem of partially used film rolls (100) remaining unused.

[0027] Alternatively, the acquisition unit 10 may acquire information on the arrival of the film rolls 100 and transmit it to the management device 30. The management device 30 may then transmit this arrival information to a display unit 50 located in the material storage area 2 where the arrived film rolls 100 are stored, causing the display unit 50 to show the arrival information of the stored film rolls 100.

[0028] With this configuration, the user can perform the task of retrieving the film roll 100 to be used for the specified product while looking at the arrival information displayed on the display unit 50, thereby reducing work errors.

[0029] The packaging device 20 here is, for example, a bag-making and packaging device, but it is not limited to a bag-making and packaging device as long as it is a packaging device that uses a film roll 100. Also, as shown in Figure 3, the packaging device 20 may be configured such that when the film roll 100 is mounted, the support shaft of the film roll 100 automatically rotates to a position where the acquisition unit 10 can read (scan) specific information, and after the acquisition unit 10 has finished scanning, it rotates in the reverse direction to return to a position where packaging processing is possible and waits, and when it receives an instruction to start production from the control device 30, it starts the packaging process.

[0030] The fixed acquisition unit 10 in Figure 3 scans the product code of the packaged item pre-printed on the film. The management device stores this product code in association with specific information acquired from the inheritance label L1 affixed to the film roll 100, so it can determine whether the installed film roll 100 matches the product (goods) to be produced.

[0031] Alternatively, the acquisition unit 10 in Figure 3 may be composed of a handheld scanner. In this case, specific information is acquired from the inheritance label L1 attached to the film roll 100 using the handheld scanner. Then, the inheritance label L1 is removed from the film roll 100, and the film roll 100 is mounted on the packaging device 20.

[0032] An example of the operation of the film roll management system 1 according to this embodiment will be described below with reference to Figure 4.

[0033] As shown in Figure 4, in step S1001, the user uses the acquisition unit 10 to acquire arrival information from the labels attached to the cardboard boxes, plastic bags, etc., containing the incoming film rolls 100.

[0034] In step S1002, the acquisition unit 10 transmits the incoming information to the management device 30. In step S1003, the management device 30 transmits the incoming information to the display unit 50 located in the material storage area 2, and the display unit 50 displays the incoming information.

[0035] Furthermore, in step S1004, the management device 30 transmits the incoming information to the label issuing device 40, and in step S1005, the label issuing device 40 issues a successor label L1 based on the incoming information. The user then affixes the successor label L1 to the corresponding film roll 100.

[0036] In step S1006, the user uses the acquisition unit 10 to acquire specific information from the inheritance label L1 attached to the film roll 100 mounted on the packaging device 20, or to the film roll 100 to be mounted.

[0037] In step S1007, the acquisition unit 10 transmits the acquired specific information to the management device 30, and in step S1008, the management device 30 determines whether the acquired specific information matches the product to be produced by the corresponding packaging device 20.

[0038] If the control device 30 determines that a match is found, in step S1009 it instructs the packaging device 20, on which the film roll 100 is attached, to start production.

[0039] In step S1010, if the packaging device 20 ends production without using up the film roll 100, it transmits the current remaining film amount to the management device 30.

[0040] In step S1011, the management device 30 transmits new specific information, including the current remaining film quantity, to the label issuing device 40, and in step S1012, the label issuing device 40 issues a new successor label. Here, the user affixes the new successor label to the film roll 100 that has finished production without being used up.

[0041] According to this method, the successor label L1 attached to the unused film roll 100 records not only the arrival information of the film roll 100, but also the replacement date when it was removed from the packaging device 20 and the remaining amount of film. Therefore, the operator can look at the successor label L1 and preferentially select and use the unused film roll 100. When such a film roll 100 is loaded into the packaging device 20, the packaging device 20 can recognize that the correct film roll 100 has been loaded and start operation.

[0042] Although the present invention has been described in detail using the embodiments described above, it will be clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Explanation of symbols]
