Description

[Technical field]

[0001] The present disclosure relates to a welding material dispensing system and method. [Background technology]

[0002] For example, welding materials are dispensed as follows: (1) A production engineer writes down welding instructions on paper and hands it over to the welder. (2) The welder checks the instructions and transfers the brand, size, amount of welding materials to be used, etc. onto a paper form for dispensing welding materials, and asks the operation foreman for confirmation and approval. (3) Once the operation foreman's approval is obtained, the welder submits the paper form for dispensing and requests the storage staff to dispense the materials. (4) The storage staff dispenses the specified amount of welding materials of the brand listed on the paper form for dispensing.

[0003] This type of operation poses the following issues. (A) Because instructions are transcribed from paper, errors occur in the brand of welding material, etc., and the wrong welding material is dispensed. (B) There is wasted effort and time involved in transcription work and waiting for the work chief's approval. (C) The person in charge of the storage facility who receives a request to dispense welding material dispenses the specified brand of welding material, but the selection of which welding material is subjective, and the old welding material (one close to its expiration date) is not always selected and dispensed. If old welding material remains, it will have to be discarded when its expiration date is reached, resulting in waste.

[0004] Patent Document 1 discloses a welding material dispensing system that aims to ensure traceability of welding materials and to prevent welding workers from misusing welding materials, but does not disclose means for solving problems (A) to (C). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2006-192449 A Summary of the Invention [Problem to be solved by the invention]

[0006] There is a need for a method for dispensing welding material that can solve the above problems (A) to (C).

[0007] The present disclosure provides a dispensing system and a dispensing method that can solve the above problems. [Means for solving the problem]

[0008] The dispensing system according to the present disclosure comprises a work instruction system, a welder terminal, and an inventory management system, the work instruction system comprising means for acquiring welding work information defining the brand of welding material to be used for each welding line to be welded from a higher-level system, means for creating welding work instruction information including the welding work information, and means for accepting approval of the instruction information, the welder terminal comprising means for accepting input of the usage amount of the brand included in the approved instruction information, and means for requesting the inventory management system to dispense the input usage amount of the brand, and the inventory management system comprising means for referencing a database for managing the inventory of the welding material, based on the brand and usage amount requested by the requesting means, and allocating the usage amount with priority to the brand with the oldest manufacturing date.

[0009] According to the dispensing method of the present disclosure, a computer used by a person instructing welding work obtains from a host system welding work information that defines the brand of welding material to be used for each weld line of a welding target, creates welding work instruction information including the welding work information, accepts approval for the instruction information, and a computer used by a welder performing the welding work accepts input of the usage amount of the brand included in the approved instruction information and requests an inventory management system that manages an inventory of welding materials to dispense the input usage amount of the brand, and the inventory management system refers to a database that manages the inventory of the welding materials based on the requested brand and usage amount, and allocates the usage amount, giving priority to the brand with the oldest manufacturing date. Effect of the Invention

[0010] According to the dispensing system and dispensing method disclosed herein, it is possible to reduce the dispensing of incorrect welding material due to transcription errors, as well as wasted labor and time in the dispensing process, and to ensure that older welding material is preferentially dispensed.

[0012] <Embodiment> The dispensing system of the present disclosure will now be described with reference to FIGS. (composition) FIG. 1 is a block diagram illustrating an example of a dispensing system according to an embodiment. The delivery system 100 includes a construction information management system 10, a welding management system 20, a work instruction system 30, a welder terminal 40, and an inventory management system 50. The construction information management system 10, the welding management system 20, the work instruction system 30, the welder terminal 40, and the inventory management system 50 are each configured by a computer.

[0013] The construction information management system 10 stores information on the contents of construction works (referred to as construction information), such as the work processes that make up one construction work, the type and number of machines required for each work process, the number of workers, the man-hours for each work process, the planned start date and planned completion date for the entire construction work, etc. The work processes may include welding work processes. For welding work processes, the work contents are managed for each weld line.

[0014] The welding management system 20 stores information (called welding line information) about the welding work process stored in the construction information management system 10, such as what kind of welding lines are included, what kind of construction is performed for each welding line, and what brand and amount of welding material is used. For example, a production engineer registers welding line information such as the construction method of each welding line and the brand and amount of welding material required for each welding work process managed by the construction information management system 10 through the welding management system 20. Then, the construction information management system 10 records the welding line information in association with the ID of the welding line. Note that the welding management system 20 is not essential. For example, the construction information management system 10 may register the welding line information in advance in association with the welding work process, or the production engineer may register the welding line information directly in the construction information management system 10 without going through the welding management system 20.

[0015] The work instruction system 30 creates instruction information for a welding work to be given to a welder, and transmits the created instruction information to the welder terminal 40. The work instruction system 30 includes an instruction information creation unit 31, an approval receiving unit 32, and an instruction unit 33.

[0016] The instruction information creation unit 31 creates instruction information for a welder. For example, a work foreman accesses the construction information management system 10 from the work instruction system 30 and refers to a list of target work. The list displays welding work information including a welding line ID, a name of a member to be welded, a construction method, a brand of welding material, a usage amount, a drawing number, and the like for each target work. The work foreman selects a welding work to be performed from the list. When the work foreman selects a welding work, information such as a welding line ID, a brand of welding material, and a welding construction method for the selected welding work is transmitted from the construction information management system 10 to the work instruction system 30. The instruction information creation unit 31 receives the information transmitted from the construction information management system 10 and outputs the welding work information to a display device or the like. The work foreman checks the output welding work information and assigns a welder to perform the work for each welding work information. The instruction information creation unit 31 stores the ID of the welder assigned by the work foreman and the ID of the welder terminal 40 used by the welder in association with each other. This eliminates the need for transcription work, and instruction information that accurately reflects the work content of the welding work registered in the construction information management system 10 is created.

[0017] The approval receiving unit 32 receives the chief's approval for the instruction information. For example, the approval receiving unit 32 outputs to the display device a screen showing an approval button and the instruction information created by the instruction information creating unit 31. The chief checks the output instruction information, and if there are no problems with the contents, presses the approval button or the like. The approval receiving unit 32 detects that the approval button has been pressed.

[0018] The instruction unit 33 transmits the instruction information after approval by the foreman to the welder terminal 40. For example, when the approval receiving unit 32 receives a press of the approval button, it notifies the instruction unit 33 of the approved instruction information. The instruction unit 33 transmits the instruction information contained in the instruction information to the welder terminal 40. As a result, the instruction contents for the welding work to be performed by the welder are transmitted to the welder terminal 40 of the welder performing the welding work. Also, since the instruction information is created by the foreman himself, the contents are confirmed, and the approved information is transmitted to the welder side, no waiting time for approval occurs.

[0019] The welding operator terminal 40 is a mobile terminal such as a tablet terminal or a smartphone carried by each welding operator who performs welding work. The welding operator terminal 40 includes a payment request unit 41 and a receipt confirmation unit 42.

[0020] The delivery request unit 41 receives the instruction information transmitted from the work instruction system 30, and outputs the instruction information, an input field for inputting information on the welding material to be delivered, and a delivery request button to the display unit of the welder terminal 40. The welder checks the construction method of the welding work to be performed and the brand of the welding material to be used. Based on the displayed instruction content, the welder inputs the brand, size, amount used, and receiving time of the welding material in the input field and presses the delivery request button. This input field is checked so that brands other than those included in the instruction information cannot be input, and is designed to prevent a different brand from being delivered by mistake. In addition, the identification information (serial number) of the welding material can be input in the input field as necessary. When the welder presses the delivery request button, the delivery request unit 41 transmits delivery request information including the brand, size, amount used, receiving time, etc. of the welding material input in the input field (for example, the serial number if input) to the inventory management system 50.

[0021] The receipt confirmation unit 42 displays the requested brand, size, and amount used (requested weight), and outputs a receipt confirmation screen on the display unit of the welder terminal 40, which displays an input field for inputting the received weight and a receipt confirmation button. The welder checks the brand, size, weight, and serial number of the welding material actually received after being dispensed from the storage, inputs the received weight and serial number on this receipt confirmation screen, and presses the receipt confirmation button. When the welder presses the receipt confirmation button, the receipt confirmation unit 42 transmits receipt confirmation information including the input received weight and serial number of the welding material to the inventory management system 50. Note that the weight is input on the receipt confirmation screen because the requested weight and the actually dispensed weight of the welding material may differ. For example, a situation may occur in which, although a request for dispensing 2 kg is made, only 1.8 kg is actually dispensed. If inventory management is performed as if 2 kg was dispensed, even though only 1.8 kg was actually dispensed, a discrepancy will occur between the actual inventory amount and the inventory amount managed in the inventory management table 200 described later. Therefore, the welder checks the weight that has actually been dispensed and provides feedback to the inventory management system 50, thereby enabling accurate inventory management.

[0022] The inventory management system 50 manages the inventory of a warehouse that stores welding materials. The inventory management system 50 includes an allocation unit 51, a printing unit 52, and an inventory update unit 53.

[0023] The allocation unit 51 receives the dispensing request information transmitted from the welding operator terminal 40, outputs the received dispensing request information to a display device of the inventory management system 50, and allocates the oldest welding material that satisfies the brand, size, and usage conditions included in the dispensing request information by referring to an inventory management table 200 stored in the inventory management system 50. FIG. 2 shows an example of the inventory management table 200. The inventory management table 200 has items such as the ID, brand, size, manufacturing date, inventory amount, warehoused date, and storage location of the welding material. As shown in the figure, multiple welding materials of the same brand and size are stored, and each is assigned a different ID. The ID in the inventory management table 200 is the manufacturing number of the welding material. Even welding materials of the same brand and size are manufactured at different times and assigned different manufacturing numbers. For example, when a request is made to dispense 2 kg of welding material of brand X1 and size 3.2, the allocation unit 51 refers to the inventory management table 200 and allocates, among the welding materials of brand X1 and size 3.2, ID=001 having the oldest manufacturing date as the material to be dispensed. For example, when a request is made to dispense 5 kg of welding material of brand X1 and size 3.2, the allocation unit 51 refers to the inventory management table 200 and allocates, among the welding materials of brand X1 and size 3.2, 2 kg of ID=001 having the oldest manufacturing date and 3 kg of ID=002 having the next oldest manufacturing date, for a total of 5 kg as the material to be dispensed. The allocation unit 51 outputs the ID, brand, size, and allocated amount (weight) of the allocated welding material to the printing unit 52.

[0024] The printing unit 52 uses a printer (not shown) to print information about the welding material allocated in response to the withdrawal request sent from the welder terminal 40 on a paper withdrawal slip. For example, when 2 kg of welding material with ID=001 and 3 kg of welding material with ID=002 are allocated, two withdrawal slips are printed: one for ID=001 and one for ID=002. The withdrawal slips have printed thereon the brand, size, amount to be withdrawn (weight), etc. of the material to be withdrawn. The person in charge of the storage facility refers to the printed withdrawal slips, takes out the allocated welding material from the storage facility by the receipt time included in the withdrawal request information, and hands (dispatch) the taken out welding material to the welder who made the withdrawal request. This allows the welding materials to be dispensed in order starting with the oldest production date.

[0025] The inventory update unit 53 receives the receipt confirmation information transmitted from the welder terminal 40, and updates the inventory management table 200. For example, assume that the registered contents of the inventory management table 200 are as shown in FIG. 2. In this state, if 2 kg of welding material with ID=001 and 3 kg of welding material with ID=002 are dispensed, the inventory update unit 53 updates the inventory amount of ID=001 to 0 kg and the inventory amount of ID=001 to 7 kg. This makes it possible to accurately manage the inventory amount of welding materials stored in the storehouse.

[0026] (operation) Next, the operation of the dispensing system 100 of this embodiment will be described. FIG. 3 shows an example of the creation and transmission process of instruction information by the dispensing system. A production engineer registers welding line information in the welding management system 20 (step S11). The welding management system 20 transmits the registered welding line information to the construction information management system 10. The construction information management system 10 receives the welding line information and reflects it in the welding work process. Next, the welding work supervisor creates instruction information using the work instruction system 30. First, the instruction information creation unit 31 acquires welding work information from the construction information management system 10 and displays it as a list. The supervisor selects welding work information of the work target from the list (step S12). Next, the supervisor links each selected welding work information to the work (operation) in which the welding is actually performed and the welder in charge of welding. The instruction information creation unit 31 acquires the welding work information and the welder linked by the supervisor and creates instruction information including these pieces of information (step S13). The instruction information includes welding work information, the name of the welder, and identification information of the welder terminal 40 used by the welder. Next, the operator checks the created instruction information and approves it if the content is correct (step S14). If the operator approves, the approval receiving unit 32 instructs the instruction unit 33 to send the instruction information. The instruction unit 33 sends the instruction information to the welder terminal 40 (step S15). For example, the instruction unit 33 has a table that associates the identification information of the welder terminal 40 with destination information such as the email address or IP address of the welder terminal 40, and transmits the instruction information to the welder terminal 40 by referring to this table.

[0027] In the conventional dispensing operation, there were problems such as (A) a transcription operation from instructions on paper media, which causes errors in the brand of welding material, etc., resulting in the wrong welding material being dispensed, and (B) wasteful labor and time such as transcription operation and waiting for the approval of the work chief. In contrast, according to the present embodiment, the instruction information is created by copying the welding work information registered in the construction information management system 10, so there are no problems due to errors in transcription (A) (for example, inputting a welding line ID incorrectly, creating an instruction not registered in the construction information management system 10, specifying a combination of welding materials that does not exist, etc.) and no labor and time required for transcription operation (B). In addition, the instruction information is sent to the welder only after the work chief creates and approves the work instructions himself, so the waiting time for approval (B) can be reduced. In addition, by sending the approved instruction information to the welder terminal 40 after the work chief's approval, the waiting time for approval can be reduced while the approval process in the conventional operation can be retained, and quality can be guaranteed.

[0028] Next, the process after transmitting the instruction information will be described with reference to FIG. When the welding operator terminal 40 receives the instruction information, the delivery request unit 41 outputs the contents of the instruction information to the display unit (step S21). When the welding operator confirms the instruction information, the welding operator requests delivery by specifying the brand, size, amount to be used, and time to be received of the welding material required for the work (presses the delivery request button). If it is necessary to specify the identification number (serial number) of the welding material, the welding operator specifies the identification number. The delivery request unit 41 transmits the delivery request information to the inventory management system 50 (step S22). In the inventory management system 50, the allocation unit 51 receives the delivery request information, and allocates welding materials from among the welding materials registered in the inventory management table 200 in order of the oldest manufacturing date among the brands and sizes specified in the delivery request information until the total delivery amount reaches the usage amount specified in the delivery request information (step S23). Next, the printing unit 52 prints information on the allocated welding materials (step S24). The person in charge of the storage facility refers to the printed delivery slip and delivers the designated amount of welding material to the welder by the delivery time. The welder who received the welding material operates the welder terminal 40 to call up the delivery confirmation screen. The delivery confirmation unit 42 displays the delivery confirmation screen. The welder checks the brand, size, weight, etc. of the delivered welding material, inputs the weight of the received brand into the delivery confirmation screen, and presses the delivery confirmation button. The delivery confirmation unit 42 transmits the delivery confirmation information to the inventory management system 50 (step S25). In the inventory management system 50, the inventory update unit 53 receives the delivery confirmation information and updates the inventory amount of the serial number included in the delivery confirmation information in the inventory management table 200 (step S26). For example, if the original inventory amount of ID=002 is 10 kg and the weight of ID=002 actually delivered, included in the delivery confirmation information, is 2 kg, the inventory update unit 53 updates the inventory amount of ID=002 in the inventory management table 200 from the original 10 kg to 8 kg.

[0029] In the conventional dispensing operation, there were problems such as (A) a mistake in the brand of the welding material occurs due to a transcription work from instructions on paper media, resulting in a mistake in the welding material to be dispensed, and (C) a person in charge of the storage facility who receives a dispensing request dispenses the specified brand of welding material, but the selection of the welding material is subjective, and the old (near expiration date) welding material is not necessarily selected and dispensed. In contrast, according to the present embodiment, the instruction information is created by copying the welding work information registered in the construction information management system 10, and a dispensing request is made based on the instruction information created in this way (for example, the brand cannot be changed), so that problems such as (A) a mistake in the welding material to be dispensed due to a transcription error, and (B) the labor required to transcribe the brand, size, usage amount, etc. of the welding material to be dispensed onto a paper form for dispensing can be prevented. In addition, according to the present embodiment, priority is given to the allocation of welding materials with older manufacturing dates in the inventory management table 200, so that the problem of (C) can be eliminated.

[0030] In addition, in the conventional operation, the welding material to be dispensed had to be prepared after receiving the dispensing slip posted by the welder, but according to the present embodiment, when a dispensing request is received from the welder terminal 40, a dispensing slip is printed, so the person in charge of the storage facility can grasp the request information in a timely manner and prepare the welding material in advance. In addition, since the receiving time can be specified in the dispensing request, the person in charge of the storage facility only needs to prepare the welding material by the specified receiving time, and the welder only needs to go to receive the welding material at the receiving time, so that both parties can use their time effectively. In addition, in the receipt confirmation, the weight of the welding material actually received by the welder can be reflected in the inventory management table 200, so accurate inventory management can be maintained.

[0031] (effect) As described above, according to this embodiment, the instruction information registered by the production engineer is reflected in the dispensing request without transcription, which prevents human errors such as transcription errors and reduces the labor and time required for transcription. In addition, by performing receipt confirmation, it is possible to ensure that the welding material is dispensed according to the instruction information. In addition, priority is given to welding materials with older manufacturing dates, so that the oldest welding materials can be dispensed with confidence, and the generation of welding materials to be discarded can be prevented.

[0032] In the above embodiment, the welding material is described as the object to be dispensed, but the dispensing method of the present embodiment can also be applied to the dispensing management of consumables such as gases and solvents used in construction work.

[0033] FIG. 5 is a diagram illustrating an example of a hardware configuration of the dispensing system according to the embodiment.
