Technical Field

[0001] The present invention relates to welding material technical management, and in particular to a welding wire drum management device, a management method and a storage medium. Background Art

[0002] At present, the conventional mode and process of issuing welding materials (such as welding wire) in the secondary welding material warehouse relies heavily on manual operation, which is reflected in three aspects. First, before the welding materials are issued, the paper version of the "Welding Material Receipt Form" is manually delivered. Second, when issuing, paper version approval, receipt information registration and filling in various data are used. Third, when issuing, the dryer and the welder must face-to-face handover of welding materials, and verify the identity information of the personnel and the welding material information.

[0003] However, in the above-mentioned traditional welding wire distribution process, manual face-to-face distribution of welding materials leads to low efficiency in distribution and collection, slow filling of paper documents, and easy errors in filling. Summary of the invention

[0004] The object of the present invention is to provide a welding wire drum management device, a management method and a storage medium, which can improve the distribution efficiency of welding wire drums.

[0009] In one embodiment, an empty bin detection mechanism is disposed on the bin bottom plate, and the empty bin detection mechanism is used to detect whether the storage bin is in an empty bin state.

[0010] In one embodiment, the rotating storage bin is provided with a reserved hole, which is located in the storage bin position and communicated with the accommodating cavity; the welding wire reel management device also includes a pushing structure; when the storage bin position and the access channel are opposite to each other, the pushing structure can pass through the reserved hole and push the welding wire reel located in the accommodating cavity to the access channel of the cabinet.

[0011] In one embodiment, the storage bin is provided with a position sensor, and the position sensor is used to determine the circumferential position angle of the storage bin in the rotating storage bin.

[0012] In one embodiment, the welding wire drum is provided with an information tag; and the welding wire drum management device further comprises an information reader for reading the information tag.

[0013] Another aspect of the present invention provides a welding wire reel management method, which is applied to a welding wire reel management device as described in any one of the above embodiments; the welding wire reel management method includes: determining the state of each storage position, determining the distance between each storage position in an empty position and an access channel, and taking the storage position with the smallest distance as the target storage position; controlling the target storage position to rotate to the access channel; storing the welding wire reel in the target storage position, and data docking between the target storage position and the welding wire reel.

[0014] In one embodiment, controlling the target storage location to rotate to the access channel includes: determining a minimum rotation angle for the target storage location to rotate to the access channel; and controlling the target storage location to rotate to the minimum rotation angle.

[0015] In one embodiment, the minimum rotation angle satisfies:

[0016]

[0017] Among them, α i is the circumferential position angle of the target storage location (located at the i-th among all the storage locations), β is the circumferential position angle of the access channel, is the angle difference between the target storage location rotating along the first direction and the circumferential position angle of the access channel, is the angle difference between the target storage location and the circumferential position angle of the access channel when the target storage location is rotated along the second direction, k is the index of the target storage location after the minimum rotation angle is determined, Δα k is the minimum rotation angle of the target storage location.

[0032] Figure 5 1 is a flow chart of an embodiment of a welding wire drum management method according to the present invention. DETAILED DESCRIPTION

[0033] At present, the main steps of manual operation for welding material distribution are:

[0034] The first step is for the work team members to fill out the paper version of the "Welding Material Requisition Form" in advance based on the welding workload of the next day. The welder team leader then assigns welders, and the welding technicians review the "Welding Material Requisition Form" and sign for confirmation.

[0035] In the second step, the welder brings his own welding wire tube and "Welding Material Receipt Form" to the secondary welding material warehouse to collect welding materials.

[0036] In the third step, the dryer takes out the corresponding welding wire from the secondary welding material warehouse according to the "Welding Material Receipt Form", counts it, and hands it over to the welder. The welder and the dryer respectively fill in the model, specification, quantity, and distribution time of the welding material and sign for confirmation. At the same time, they stick a "Welding Material Label" on the welding wire tube.

[0037] However, manual distribution leads to low efficiency in distribution and collection, slow filling out of paper documents, and easy errors in filling out documents.

[0038] Reference will now be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided to explain the present invention, not to limit the present invention. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made in the present invention without departing from the scope or spirit of the present invention. For example, a feature illustrated or described as part of one embodiment may be used together with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover these modifications and variations within the scope of the appended claims and their equivalents.

[0039] The term "welding wire drum" refers to a container for storing welding wire, which is usually a cylindrical structure. A reel may be provided inside the welding wire drum for winding the welding wire; or the welding wire drum may be an empty drum for placing straight welding wire.

[0040] Figures 1 to 3 The structure of an embodiment of the welding wire drum management device of the present invention is shown. Figure 1 This is the front view of the wire drum management device. Figure 2 This is a front view of the wire barrel management device with the cabinet hidden. Figure 3 This is a top view of the welding wire drum management device with the cabinet hidden.

[0041] like Figures 1 to 3 As shown, the welding wire drum management device of the present invention includes a cabinet 100 and a rotating storage bin 200. The cabinet 100 has a certain space inside, and the rotating storage bin 200 is arranged in the cabinet 100. An operation screen 110 and a reserved inspection port 120 are arranged on the cabinet 100. The reserved inspection port 120 is convenient for maintenance personnel to perform inspection and maintenance.

[0042] The operation screen 110 is located above the cabinet 100, and provides a human-machine interaction, machine-machine interaction terminal, and an information display terminal. The administrator can perform various operations through the operation screen 110, such as querying the inventory information and location information of the welding wire drum, manually controlling the rotation of the rotating storage bin 200, setting system parameters (such as temperature and humidity thresholds, etc.), and viewing the operating status and fault alarm information of the system. The screen of the operation screen 110 can be displayed to the administrator in an intuitive graphical interface or text information, so that the administrator can manage and monitor the management cabinet conveniently and quickly.

[0043] Combination Figure 2 and Figure 3The rotating storage bin 200 is provided with a plurality of storage bins 210 in the circumferential direction. The storage bins 210 are used to store welding wire drums (not shown). The storage bins 210 are the smallest units for storing welding wire drums. The number of storage bins 210 is not limited to Figure 3 The 18 shown may be determined according to the structure of the rotary storage bin 200 and the number of welding wire drums that need to be stored simultaneously.

[0044] Combination Figure 1 and Figure 3 The cabinet 100 is provided with an access passage 130, which connects the inside and outside of the cabinet 100. The access passage 130 and the operation screen 110 can be arranged on the same panel of the cabinet 100 (front view). Figure 1 The access channel 130 is provided with an access door (not shown). When the wire tube needs to be stored or collected, the access door is opened; at other times, the access door is closed.

[0045] The rotating storage bin 200 can rotate axially. When one storage bin 210 among the multiple storage bins 210 rotates to be opposite to the access channel 130, the welding wire reel can be taken out from the storage bin 210 or stored in the storage bin 210 through the access channel 130, thereby realizing the storage or collection of the welding wire reel.

[0046] The welding wire spool management device of the present invention adopts a rotating welding wire spool storage structure. When the welding wire spool needs to be stored, the rotating storage bin 200 rotates to rotate the storage bin position 210 in an empty bin state to the access channel 130; when the welding wire spool needs to be collected, the rotating storage bin 200 rotates to rotate the storage bin position 210 storing the welding wire spool to be collected to the access channel 130, thereby realizing the automatic storage and collection of the welding wire spool without the need for manual face-to-face distribution, thereby improving the efficiency of the dryer in distributing the welding wire and the welder in collecting the welding wire, and reducing the probability of incorrect distribution and collection.

[0047] At the same time, the rotary design enables the welding wire drum management device of the present invention to provide a larger welding wire drum storage capacity under a limited floor space.

[0048] In one embodiment, the welding wire drum management device further includes a rotating shaft 300 and a rotating driving member 400. The rotating shaft 300 and the rotating storage bin 200 are coaxially arranged, and the rotating driving member 400 is connected to the rotating shaft 300 to drive the rotating shaft 300 to rotate, thereby driving the rotating storage bin 200 to rotate. The rotating driving member 400 further includes a driving motor 410, a transmission belt 420, and a bearing 430.

[0049] Specifically, the drive motor 410 provides rotational power to drive the rotation of the entire rotating storage bin 200, so as to realize the operation of storing and retrieving the welding wire tubes in the storage bins 210 at different positions. The conveyor belt is connected to the output shaft of the drive motor 410. Driven by the drive motor 410, the conveyor belt transmits power smoothly through the cooperation with the bearing 430, so as to ensure that the rotating storage bin 200 can rotate according to the predetermined trajectory and speed. The bearing 430 is used to support the rotating shaft 300, reduce friction, ensure the smoothness and stability of the rotation process, and improve the service life and operation efficiency of the mechanism.

[0050] like Figure 3 As shown, the rotating storage bin 200 is cylindrical, and the storage bins 210 are arranged at intervals along the circumference of the cylindrical rotating storage bin 200. The rotating storage bin 200 can be cylindrical, which can make full use of the space. By arranging the welding wire barrels closely in the circumferential direction, more welding wire barrels can be stored compared to the traditional linear storage method. For example, under the same ground space occupation, the number of welding wire barrels stored in the cylindrical rotating storage bin 200 may be about 1.5-2 times that of ordinary shelf storage, which can effectively reduce the floor space occupied by the storage equipment for welding workshops with a large amount of welding wire.

[0051] Furthermore, the storage positions 210 are evenly arranged in the circumferential direction of the rotating storage bin 200 , that is, the circumferential position angles between adjacent storage positions 210 are the same, which makes it easy to determine the actual positions and rotation angles of different storage positions 210 .

[0052] Generally speaking, the length of the welding wire drum is about 1 m. If the welding wire drum is disposed transversely in the cabinet 100 , that is, the axial direction of the rotating storage bin 200 is parallel to the bottom surface of the cabinet 100 , the overall area occupied by the welding wire drum management device is relatively large.

[0053] In one embodiment, if Figure 2 As shown, the cylindrical rotating storage bin 200 is vertically arranged in the cabinet 100, that is, the axial direction of the rotating storage bin 200 is perpendicular to the bottom surface of the cabinet 100. The storage bin 210 extends along the axial direction of the rotating storage bin 200. The welding wire drum is vertically stored in the rotating storage bin 200 to further improve the space utilization. The axial length of the storage bin 210 is adapted to the length of the welding wire drum to match the structure of the welding wire drum.

[0054] Specifically, the storage bin 210 includes a bin bearing surface 211, a bin bottom plate 212, and a bin opening 213. The bin bearing surface 211 is recessed from the outer circumference of the rotating storage bin 200 toward the central axis of the rotating storage bin 200, and the bin bearing surface 211 and the bin bottom plate 212 are connected to form a receiving chamber 214 for receiving the welding wire tube, and the receiving chamber 214 is connected to the bin opening 213. When one of the storage bins 210 among the plurality of storage bins 210 is rotated to be opposite to the access channel 130, the receiving chamber 214 of the storage bin 210 is connected to the access channel 130 through the bin opening 213.

[0055] The design of the storage bin 210 should take into account the size and stability of the wire drum to ensure that the wire drum will not fall or shift during the rotation process. Each storage bin 210 can correspond to a unique number or position identifier to facilitate positioning and management of the control system.

[0056] The bin bearing surface 211 is matched with the outer peripheral wall of the welding wire barrel. Figure 3 As shown, the radial cross section of the bin bearing surface 211 is U-shaped, which can be adapted to the cylindrical welding wire drum. When the welding wire drum is placed in the accommodating cavity 214, the outer peripheral wall of the welding wire drum can fit the arc surface of the bin bearing surface 211 to prevent the welding wire drum from shaking or even falling out during rotation.

[0057] In one embodiment, an empty bin detection mechanism is provided on the bin bottom plate 212, and the empty bin detection mechanism is used to detect whether the storage bin 210 is in an empty bin state. The empty bin state indicates that no welding wire reel is stored in the storage bin 210, and the non-empty bin state (or full bin state) indicates that a welding wire reel is stored in the storage bin 210.

[0058] Each storage bin 210 is provided with an empty bin detection mechanism. When the dryer stores the welding wire drum, the storage bin 210 with storage capacity is determined by judging whether each storage bin 210 stores welding wire drums.

[0059] like Figure 4 As shown, the empty bin detection mechanism may be a pressure plate 230 and a switch (not shown). The pressure plate 230 is arranged on the bin bottom plate 212 of the storage bin 210. When a welding wire drum is placed, the gravity of the welding wire drum placed on the pressure plate 230 is used to press the pressure plate 230 downward, thereby triggering the switch, and at this time, the storage bin 210 is determined to be in a full bin state; when the welding wire drum is taken out, the pressure plate 230 is released, the switch is released, and at this time, the storage bin 210 is determined to be in an empty bin state. The empty bin detection mechanism may also be a pressure sensor, and the pressure obtained by the pressure sensor is used to determine whether a welding wire drum is stored.

[0060] In one embodiment, the rotating storage bin 200 is provided with a reserved hole 220, which is located in the storage bin 210 and communicates with the accommodating chamber 214. The welding wire barrel management device further includes a pushing structure (not shown). When the storage bin 210 and the access channel 130 are opposite, the pushing structure can pass through the reserved hole 220 and push the welding wire barrel in the accommodating chamber 214 to the access channel 130 of the cabinet 100, so that the welding wire barrel is smoothly pushed out of the bin. The pushing structure can be optionally a retractable push rod or a mechanical arm.

[0061] In one embodiment, the storage bin 210 is provided with a position sensor (not shown), which is used to determine the circumferential position angle of the storage bin 210 in the rotating storage bin 200, that is, to determine the angle value of the position of each storage bin 210 on the circumference.

[0062] The position sensor can be a photoelectric encoder with high accuracy. The position sensor is connected to the rotating shaft 300. As the rotating storage bin 200 rotates, the position information of each storage bin 210 can be fed back to the control system in real time. The control system compares the feedback position information with the preset path, and once a deviation is found, the control signal of the motor is adjusted immediately for correction. For example, if the theoretical position of the target wire drum should be at a certain angle, but the actual position feedback by the sensor deviates, the control system will speed up or slow down the speed of the motor according to the size and direction of the deviation, so that the wire drum returns to the correct path as soon as possible.

[0063] By setting a position sensor, the position of the welding wire drum in the rotating storage bin 200 can be precisely controlled so that it can accurately stop at the designated access position. The position information fed back by the position sensor is compared with the preset position data, and then the operation of the rotating drive member 400 is controlled to achieve precise adjustment of the position of the welding wire drum. For example, when an instruction to take out a welding wire drum with a specific number is received, the corresponding welding wire drum is rotated to the access channel 130 by quickly starting the drive motor 410.

[0064] In one embodiment, the welding wire drum is provided with an information tag. The dryer can use a printer to print the information tag, and attach the information tag to the welding wire drum by pasting or other means. The information tag can be an RFID tag or a barcode.

[0065] The welding wire drum management device further includes an information reader 140 for reading the information tag. The information reader 140 is used to read the information tag on the welding wire drum. The information reader 140 is arranged on the panel of the cabinet 100 where the operation screen 110 is located. The information reader 140 can be optionally an RFID identifier or a barcode scanner.

[0066] The welding wire drum management device of the present invention further includes an industrial computer 500. The industrial computer 500 is used to receive data from various sensors, including data from position sensors. The industrial computer 500 processes and analyzes the data according to preset programs and algorithms. Then, control instructions are sent to other devices such as the drive motor 410 and the operation screen 110 to coordinate the collaborative work between various components, thereby realizing the intelligent operation and various functions of the welding wire drum management device.

[0067] The welding wire drum management device of the present invention enables the dryer to easily put the welding wire drum through the access channel 130 for the welder to pick up without the need to search and carry it tediously as in the traditional way when distributing the welding wire drum. For the welder, it is also convenient to directly obtain the required welding wire drum from the access channel 130, which greatly realizes the automatic storage and collection function of the welding wire drum, effectively improves the efficiency and convenience of the welding wire management work in the links of the dryer distributing the welding wire and the welder using the welding wire, reduces the mistakes and time waste that may be caused by manual operation, and lays a solid foundation for the efficient operation of the entire welding production process.

[0068] Figure 5 The welding wire drum management method of the present invention is shown. The welding wire drum management method of the present invention is applied to the welding wire drum management device described in the above embodiment.

[0069] like Figure 5 As shown, the welding wire drum management method of the present invention includes steps S100 to S300:

[0070] In step S100, the state of each storage bin is determined, the distance between each storage bin in an empty state and the access channel is determined, and the storage bin with the shortest distance is used as the target storage bin.

[0071] Among them, the state can be determined by an empty storage detection mechanism provided on each storage position, and the storage position in an empty storage state can be used as a storage position to be selected.

[0072] The position of each storage location to be selected is determined by a position sensor, the distance between each storage location to be selected and the access channel is calculated, and the storage location to be selected with the shortest distance is used as the target storage location.

[0073] In step S200, the target storage location is controlled to rotate to the access channel.

[0074] In step S300, the welding wire reel is stored in a target storage location, and data connection is performed between the target storage location and the welding wire reel.

[0075] Among them, an information tag is attached to the welding wire reel, and the information of the welding wire reel is read by an information reader arranged on the cabinet, and then the target storage position and the welding wire reel are data-connected.

[0076] In one embodiment, step S200 further includes steps S210 to S220:

[0077] In step S210, a minimum rotation angle of the target storage location to the access channel is determined.

[0078] In step S220, the target storage location is controlled to rotate by a minimum rotation angle.

[0079] Among them, the minimum rotation angle satisfies:

[0080]

[0081] In equation (1), α i is the circumferential position angle of the target storage location (the i-th storage location among all storage locations), β is the circumferential position angle of the access channel, is the angle difference between the target storage location and the circumferential position angle of the access channel when the target storage location is rotated along the first direction, is the angle difference between the target storage location and the circumferential position angle of the access channel when the target storage location is rotated along the second direction, k is the target storage location index after the minimum rotation angle is determined, Δα k The minimum rotation angle of the target storage location.

[0082] It should be noted that Δα k Represents the attribute attached to the minimum rotation, k represents the index of the attribute, k = i, Δα k =minΔα o .

[0083] After the minimum rotation angle of the target storage location is determined according to equation (1), Δα k , that is, the minimum rotation angle and the rotation direction (first direction or second direction) are determined at the same time. The first direction can be selected as follows Figure 3 The second direction is clockwise from the top view, and the second direction may be the opposite direction to the first direction, that is, the counterclockwise direction. The rotation speed v of the rotary storage cabinet is a constant value, and the unit is degree / second (° / s). The rotation angular velocity ω=v.

[0084] Relation (1) can avoid repeated calculation of angle difference by using modular operation, and considers optimization in both clockwise and counterclockwise directions. By comparing the angle difference in the two directions, the optimal direction is selected and the rotation time is calculated.

[0085] by Figure 3 Taking the rotating storage bin shown in the figure as an example, 18 (the number of storage bins N=18) storage bins are evenly spaced on the circumference. Figure 3In the rotating storage bin shown, the storage bin at the bottom is opposite to the access channel, and this storage bin is referred to as the first storage bin. The circumferential position angle α1 of the first storage bin is 0°, and the circumferential position angle β of the access channel is 0°. The storage bins are numbered in a counterclockwise direction, and the one on the right side of the first storage bin is referred to as the second storage bin, and so on, the one on the left side of the first storage bin is referred to as the eighteenth storage bin.

[0086] The angle difference between adjacent storage locations satisfies:

[0087]

[0088] In equation (2), θ is the angle difference between adjacent storage locations, N is the number of storage locations, and N is a positive integer greater than or equal to 2. Figure 3 In the example shown, N=18 and θ=20°.

[0089] The circumferential position angles of each storage location satisfy:

[0090] α i =(i-1)·θ (3)

[0091] In equation (3), α i is the circular position angle of the i-th storage location, where i is a positive integer.

[0092] Combining equations (2) and (3), the circumferential position angle of the second storage bin is α2 = (2-1) × 20° = 20°, and the circumferential position angle of the third storage bin is α3 = (3-1) × 20° = 40°. By analogy, the circumferential position angles of the storage bins can be obtained, and the circumferential position angles are used as the initial state angles.

[0093] According to step S100, for example, after determining that the second storage location is the target storage location, the relationship (1) is used to calculate That is to say, the second storage position can reach the access channel (0° position) by rotating 20° clockwise or 340° counterclockwise. k =20°, and the rotation direction is clockwise. The time required for rotation satisfies:

[0094]

[0095] In equation (4), t k is the time required for one storage bin to rotate, and ω is the angular velocity of the rotating storage bin.

[0096] For the storage operation of M welding wire drums, the total time consumed satisfies:

[0097]

[0098] In equation (5), TotalTime is the total time consumed, t m is the time required for the mth storage bin to rotate to the access channel, t m It can be calculated according to equation (4), where m and M are both positive integers, and M ≥ m. T is the fixed time consumed by each storage bin during the rotation process, which can be understood as the system response time.

[0099] In one embodiment, the welding wire drum management method further includes step S400:

[0100] In step S400, the actual status and actual position of the target storage location are updated.

[0101] After the rotation operation is completed, the wire drum is stored or picked up, and the wire drum status is updated in real time, marking it as out of the warehouse or in the warehouse, that is, the status of the storage bin is updated to an empty bin state or a full bin state. According to the rotation direction and angle, the update formula is as follows:

[0102] If the target storage location is along the first direction (eg Figure 3 The actual position of the target storage bin satisfies:

[0103] α i ′=(α i +Δα k )mod 360° (6)

[0104] If the target storage location is along the second direction (e.g. Figure 3 The actual position of the target storage bin satisfies:

[0105] α i ′=(α i -Δα k +360°)mod 360° (7)

[0106] In equations (6) and (7), α i ′ is the updated circular position angle of the target storage location.

[0107] Equations (6) and (7) can be understood as updating the position of the storage bin based on the initial angle and the rotation angle.

[0108] In order to optimize the storage location index update, the discrete index calculation formula can be used to avoid floating point operation errors and ensure high-precision position update. Equation (8) is the index update formula:

[0110] In equation (8), i′ is the updated target storage location index, i is the initial index of the target storage location, and θ is the circumferential position angle between adjacent storage locations.

[0111] It should be noted that during the wire reel collection process, the position of the storage bin corresponding to the wire reel to be collected is first determined (for example, the Xth storage bin), and then the minimum rotation angle is determined according to equation (1). Please refer to steps S200 to S400 and will not be repeated here.

[0112] In combination with the welding wire drum management device and the welding wire drum management method of the present invention, the specific process of the dryer storing the welding wire drum and the welder receiving the welding wire drum is as follows:

[0113] 1. Receive welding material requisition form:

[0115] 1.2. According to the content of the requisition form, the dryer prepares the welding materials and puts them into the empty welding wire tube of the corresponding welder.

[0116] 2. Print and attach labels:

[0117] 2.1. The dryer uses a dedicated printer to print information labels with RFID tags and / or barcodes to ensure that the label information is accurate.

[0118] 2.2. Attach the printed information label to the wire reel for easy subsequent identification and tracking.

[0119] 3. Log in to the management cabinet and prepare for storage:

[0120] 3.1. The dryer logs in his / her own account on the operation screen of the welding wire drum management device of the present invention.

[0121] 3.2. Click the "Store" button on the operation screen to prepare for the storage of the welding wire reel.

[0122] 4. Automatic allocation of storage space in the management cabinet:

[0123] 4.1. The empty storage location is determined by the empty storage location detection mechanism to be an empty storage location (for example: storage location No. X, No. XX, storage location No. X).

[0124] 4.2. Calculate the storage location closest to the access channel as the target storage location (such as "storage location No. X").

[0125] 4.3. Determine the solution with the shortest rotation time for the target storage location by calculating the path.

[0126] 4.4. Move the target storage location to the access channel to facilitate storage by the dryer.

[0127] 5. Data connection and storage:

[0128] 5.1. The dryer uses an information reader (such as a handheld RFID scanner) to scan the information tag (such as RFID tag information) on the welding wire drum.

[0129] 5.2. Connect the data information of the welding wire drum with the target storage location to ensure the consistency of information.

[0130] 5.3. Place the welding wire tube into the target storage location.

[0131] 5.4. Click "Finish" on the operation screen to confirm the storage operation.

[0132] 6. Information transmission and reminder:

[0133] 6.1. The welding material collection information and the storage location of the welding wire tube are transmitted to the welder’s mobile phone APP in the form of data.

[0134] 6.2. The welder receives a reminder on his mobile phone APP, informing him to pick up the wire drum at the No. X wire drum management device.

[0135] The storage medium of the present invention is used to store non-transitory computer instructions. When the non-transitory computer instructions are executed, the above-mentioned welding wire drum management method is executed.
