Description

Technical Field

[0001] This invention belongs to the field of chip management technology, and particularly relates to an intelligent management system for chip storage and operation. Background Technology

[0002] Mandrels are a crucial component in seamless steel pipe production lines. During pressing or sintering, the mandrel is used to "form" the contour of the mold parts along the pressing direction. In the production of seamless steel pipes, the mandrel is inserted into the pipe body. As an important forming tool, the mandrel, in addition to possessing high strength and wear resistance, also needs to have high surface quality.

[0003] Mandrels have three main states in the seamless steel pipe production line: preparation (mandrel inspection and repair), storage (mandrel storage), and use (mandrels are put into use in the seamless steel pipe production line). The mandrels flow between these three states.

[0004] Currently, the handling of core rods in various scenarios relies on manual management. This involves manually operating overhead cranes for lifting and transporting the core rods, manually reading the stamped serial numbers, and manually filling out usage records. Therefore, the processes of core rod preparation, storage, use, and management all require a large number of personnel, resulting in low efficiency, high labor costs, significant safety hazards, and difficulty in meeting the needs of future information-based and intelligent production lines.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] refer to Figure 1 An embodiment of the present invention provides a smart management system for the operation of a chip rod warehouse, the smart management system comprising:

[0037] The mandrel preparation area 1 is equipped with a mandrel reprocessing return table 11, a mandrel processing line 12, and a mandrel transverse transfer table 13. The mandrel reprocessing return table 11 is used to place mandrels that fail surface inspection and are returned from the mandrel use area 3. The mandrel processing line 12 is used for reprocessing the problematic mandrels. The mandrel transverse transfer table 13 is used to store new mandrels and reprocessed problematic mandrels.

[0038] The core rod storage area 2 is located between the core rod preparation area 1 and the core rod usage area 3. It is equipped with a first core rod storage rack 21 and a second core rod storage rack 22. A first core rod transport roller conveyor 4 is provided between the first core rod storage rack 21, the second core rod storage rack 22 and the core rod transverse transfer platform 13. The first core rod storage rack 21 is close to the core rod preparation area 1 and the second core rod storage rack 22 is close to the core rod usage area 3. The second core rod storage rack 22 is used to store core rods used online, as well as core rods that need to be put into use in the next batch or subsequent batches. The first core rod storage rack 21 is used to store core rods that are put into use after the core rods stored in the second core rod storage rack 22. Each core rod storage rack is equipped with a paired core rod storage and retrieval mechanism for storing and retrieving core rods.

[0039] The core rod usage area 3 is equipped with a core rod usage processing line 31 and a problematic core rod storage rack 32. A second core rod transport roller conveyor 5 is provided between the core rod usage processing line 31 and the second core rod storage rack 22. The core rod usage processing line 31 is used for surface inspection and processing of core rods before use. The problematic core rod storage rack 32 is used to store problematic core rods that fail the surface inspection on the core rod usage processing line 31.

[0040] The crane can move between the mandrel preparation area 1 and the mandrel use area 3, and can be used to lift the mandrel.

[0041] Specifically, in the intelligent management system for chip rod storage and operation provided in one embodiment of the present invention, when there are prepared chip rods that can be put into use later, the chip rods are first temporarily stored on the chip rod transverse transfer platform 13. Then, according to the information of the chip rods to be stored (including the chip rod's usage time), the corresponding storage rack and its storage position on the storage rack are determined. The chip rods on the chip rod transverse transfer platform 13 are sent to the corresponding first chip rod storage rack 21 or second chip rod storage rack 22 through the first chip rod transport roller 4. After the chip rods are sent to the corresponding chip rod storage rack, the chip rod storage and retrieval mechanism is used to lift the chip rods to the corresponding positions for storage. When the chip rods need to be used, the chip rod storage and retrieval mechanism is used to lift the chip rods to be used from the second chip rod storage rack 22 and place them on the second chip rod transport roller 5. The second chip rod transport roller 5 sends the chip rods on it to the chip rod use processing line 31 for surface inspection before use. If the surface inspection of the chip rods is qualified, the surface treatment of the chip rods continues, and the surface-treated chip rods continue to be used. The mandrel is conveyed along the second mandrel transport roller 5 to the corresponding usage device (mandrel limiting device). If the surface inspection of the mandrel fails, the problematic mandrel is directly hoisted to the problematic mandrel storage rack 32 by a crane. Then, the next mandrel to be used is hoisted from the second mandrel storage rack 22 and placed on the second mandrel transport roller 5 using the mandrel storage and retrieval mechanism. Surface inspection of the mandrels on the second mandrel transport roller 5 continues until a mandrel with a qualified surface inspection is found. When the problematic mandrel... When problematic mandrels are present on storage rack 32 or when a certain number of problematic mandrels are stored there, they are hoisted to mandrel reprocessing return rack 11 by a crane. When problematic mandrels are present on mandrel reprocessing return rack 11 or when a certain number of problematic mandrels are stored there, they are sent to mandrel processing line 12. Mandrel processing line 12 reprocesses the problematic mandrels to eliminate surface defects. After reprocessing, the problematic mandrels are sent to mandrel transverse transfer rack 13 for storage, awaiting subsequent storage. When steel pipe production changes specifications or is suspended, mandrels in use online are returned to the second mandrel transport roller conveyor. The returned mandrels undergo surface inspection. If the surface inspection is qualified, the mandrels are returned to the second mandrel storage rack 22 for storage, awaiting use when needed in subsequent steel pipe production. If the surface inspection is unqualified, the mandrels are directly hoisted to problematic mandrel storage rack 32 by a crane, awaiting subsequent delivery to mandrel preparation area 1 for reprocessing.

[0042] In one embodiment of the present invention, the information of the mandrel, in addition to the usage time of the mandrel, can also be specifically set according to actual needs, such as including one or more of the following: the production batch, outer diameter, length, and planned storage time of the mandrel.

[0043] Furthermore, in one embodiment of the present invention, the intelligent management system for mandrel storage and operation is further provided with an information management and control module, which is used to manage and control the information of mandrels in the management system.

[0044] Furthermore, in order to facilitate the reprocessing of problematic core rods and improve the management efficiency of the intelligent management system for core rod storage and operation, in one embodiment of the present invention, the core rod preparation area 1 is further provided with a third core rod storage rack 14, a third core rod transport roller conveyor 6 is provided between the third core rod storage rack 14 and the core rod reprocessing return table 11, and a fourth core rod transport roller conveyor 7 is provided between the third core rod storage rack 14, the core rod processing line 12 and the core rod transverse moving table 13. The third core rod storage rack 14 is used to store problematic core rods to be reprocessed, and the third core rod storage rack 14 is provided with a paired core rod storage and retrieval mechanism for storing and retrieving core rods.

[0045] Specifically, when there are problematic mandrels on the return table 11 for reprocessing, or when the number of problematic mandrels stored reaches a certain quantity, the problematic mandrels are placed on the third mandrel transport roller 6 to be transported to the third mandrel storage rack 14 for storage. When the problematic mandrels need to be reprocessed, the mandrel storage and retrieval mechanism is used to lift the problematic mandrels from the third mandrel storage rack 14 and place them on the fourth mandrel transport roller 7. The fourth mandrel transport roller 7 then sends the mandrels on it to the mandrel processing line 12 for reprocessing. The reprocessed mandrels continue to be sent to the mandrel transverse transfer table 13 via the fourth mandrel transport roller 7 for temporary storage, awaiting subsequent storage.

[0046] Furthermore, in one embodiment of the present invention, a mandrel processing and detection device 15 is also provided on the third mandrel transport roller 6 between the third mandrel storage rack 14 and the mandrel reprocessing return table 11. The mandrel processing and detection device 15 is used to perform surface detection on the problematic mandrels transported on the third mandrel transport roller 6 to determine the surface quality problems of the problematic mandrels.

[0047] In one embodiment of the present invention, by setting up a mandrel processing and detection device 15 to detect the surface quality problems of problematic mandrels, the reprocessing process required for problematic mandrels can be determined based on the detection results of the surface quality problems, thereby ensuring that the surface inspection of mandrels reprocessed by the mandrel processing line 12 is qualified and improving the management efficiency of mandrels.

[0048] Furthermore, in one embodiment of the present invention, the mandrel storage rack adopts a truss structure.

[0049] refer to Figure 1-2 As an example, the mandrel storage rack includes: a support rod 81 and a plurality of support crossbars 82 disposed on both sides of the support rod 81. The support crossbars 82 are provided with V-shaped grooves in the transverse direction. The V-shaped grooves are used to place the support mandrels, and the bottom of the V-shaped grooves is provided with slots.

[0050] By adopting the above structure, it is possible to ensure that the core rod is stably stored in the core rod storage rack and to prevent the core rod from falling off.

[0051] refer to Figure 1-2 In one embodiment of the present invention, the core rod storage rack may include a plurality of support rods 81 arranged side by side, and each support rod 81 is provided with a plurality of support crossbars 82 on one or both sides to increase the number of core rods that the core rod storage rack can store.

[0052] Further, refer to Figure 1-2 In one embodiment of the present invention, the mandrel access mechanism includes:

[0053] The column 91 includes at least four columns, with at least two columns 91 provided on each side of the core rod storage rack;

[0054] The movable crossbeam 92 includes two beams, one of which is installed on each of the uprights 91 on both sides of the core rod storage rack.

[0055] The storage trolley 93 is mounted on the moving crossbeam 92 and can move along the moving crossbeam 92. The storage trolley 93 is equipped with a material hook 94 that can move up and down.

[0056] Specifically, when it is necessary to store the mandrel, the storage trolley 93 is controlled to move along the moving beam 92 to the first mandrel transport roller 4, and then the material hook 94 is controlled to lift and lower to hook the mandrel. After the mandrel is hooked, the storage trolley 93 is controlled to move along the moving beam 92 to the corresponding storage position of the mandrel, the material hook 94 is controlled to lift and lower, and the storage trolley 93 is controlled to move along the moving beam 92 until the mandrel is hoisted to the corresponding support beam 82, and the material hook 94 is controlled to release so that the mandrel is placed on the support beam 82. When it is necessary to lift the mandrel, control the storage trolley 93 to move along the moving beam 92 to the corresponding storage position of the mandrel, control the material hook 94 to rise and fall, and control the storage trolley 93 to move along the moving beam 92 until the material hook 94 reaches above the mandrel, and control the material hook 94 to hook the mandrel; after the mandrel is hooked, control the storage trolley 93 to move along the moving beam 92 to the second mandrel transport roller 5, control the material hook 94 to release, so that the mandrel can be placed on the second mandrel transport roller 5.

[0057] Furthermore, as an example, the retrieval trolley 93 is movably connected to the moving beam 92 via a gear transmission mechanism or a chain transmission mechanism. Specifically, when the retrieval trolley 93 is movably connected to the moving beam 92 via a gear transmission mechanism, a gear and a drive motor connected to the gear are provided on the retrieval trolley 93, and a rack that can mesh with the gear is provided on the moving beam 92 along its transverse direction. When the retrieval trolley 93 is mounted on the moving beam 92, the gear and the rack mesh with each other, thereby driving the gear to rotate through the drive motor, thus driving the retrieval trolley 93 to move along the moving beam 92.

[0058] Furthermore, as an example, the material hook 94 adopts a claw-shaped material hook, one end of which is used to hook the core rod, and the other end is connected to a drive cylinder. The drive cylinder is used to control the rotation of the claw-shaped material hook to open and clamp the claw-shaped material hook.

[0059] Further, refer to Figure 2 As an example, the material hook 94 is controlled to lift and lower via a telescopic hydraulic cylinder. Specifically, a guide rod 95 and a telescopic hydraulic cylinder are installed on the storage trolley 93. A horizontal plate 96 is fitted onto the guide rod 95, and the material hook 94 is installed on the horizontal plate 96. The output end of the telescopic hydraulic cylinder is connected to the horizontal plate 96, and the lifting and lowering of the horizontal plate 96 and the material hook 94 on it is achieved through the telescopic movement of the hydraulic cylinder.

[0060] refer to Figure 1 Furthermore, in one embodiment of the present invention, a lifting frame 23 is provided on one side of the second core rod storage rack 22. The lifting frame 23 is used to store core rods to be used within the working range of the core rod storage and retrieval mechanism paired with the second core rod storage rack 22.

[0061] By setting up a lifting frame 23 to store the mandrels to be used, the mandrels can be lifted in advance, so that they can be quickly put into use when needed, thereby improving production efficiency.

[0062] Further, refer to Figure 1 In one embodiment of the present invention, the mandrel processing line 31 includes an induction heating device 311, a surface detection device 312 and a surface lubrication spraying device 313 arranged sequentially along the second mandrel transport roller 5.

[0063] The induction heating device 311 is used to heat the mandrel;

[0064] The surface inspection device 312 is used to inspect the surface of the mandrel to determine whether the mandrel surface is qualified;

[0065] The surface lubrication spraying device 313 is used to perform surface lubrication spraying on mandrels that have passed surface inspection.

[0066] Specifically, when the mandrel processing line 31 processes the mandrels on the second transport roller conveyor 5, the induction heating device 311 first heats the mandrels to reach the set temperature. Then, the mandrels heated by the induction heating device 311 are transported to the surface inspection device 312 via the second transport roller conveyor 5. The surface inspection device 312 inspects the surface of the mandrels to determine whether the surface quality of the mandrels is qualified. If not, the mandrels that fail the surface inspection are hoisted by a crane to the problematic mandrel storage rack 32 for storage. If they are qualified, they continue to be transported to the surface lubrication spraying device 313 via the second transport roller conveyor 5. The surface lubrication spraying device 313 lubricates and sprays the surface of the mandrels. The sprayed mandrels continue to be transported to the corresponding application device (such as the mandrel movement limiting device) via the second transport roller conveyor 5.

[0067] Furthermore, in one embodiment of the present invention, a mandrel number information acquisition device is provided between the surface detection device 312 and the surface lubrication spraying device 313. The mandrel number information acquisition device is used to read the number information of the mandrels on the second transport roller 5.

[0068] The mandrel numbering information acquisition device is communicatively connected to the information management and control module of the management system.

[0069] With this setup, during the mandrel transportation process, the mandrel's information will be read by the mandrel number information acquisition device, which will then transmit the read information to the information management and control module. This facilitates real-time updates of usage information and intelligent control of mandrel transportation, processing, and hoisting by the intelligent management system, ensuring the normal and orderly operation of the intelligent management system.

[0070] The specific structure of the core rod number information acquisition device can be set according to actual needs. For example, the core rod number information acquisition device can use radio frequency identification (RFID) equipment or video acquisition and identification equipment.

[0071] Furthermore, in one embodiment of the present invention, photoelectric switches and / or proximity switches are provided on multiple mandrel transport rollers, and the photoelectric switches and proximity switches are used to detect the position of the mandrel on the mandrel transport rollers.

[0072] Among them, the photoelectric switch and the proximity switch are connected to the information management and control module.

[0073] With this setup, the position of the mandrel can be tracked and determined in real time throughout the entire mandrel circulation process, ensuring the orderly progress of the mandrel circulation process.

[0074] Furthermore, in one embodiment of the present invention, the information management and control module is equipped with multiple functional units, including WMS (Warehouse Management System), MES (Manufacturing Execution System), and WCS (Warehouse System Control System). The placement position of the mandrel is determined according to the production plan of the MES. The WMS can interact with the MES, and the WCS can execute the requirements of the WMS and arrange the placement position of the mandrel according to the production sequence.

[0075] Furthermore, in one embodiment of the present invention, the trolley is an intelligent trolley, which is communicatively connected to the information management and control module, and the information management and control module automatically controls the movement of the intelligent trolley according to the actual mandrel hoisting requirements.

[0076] An embodiment of the present invention provides an intelligent management system for chip bar storage and operation. By setting up multiple partitions and three-dimensional storage racks capable of storing chip bars, specific chip bars are stored using different storage racks. Chip bar access carts enable rapid access to chip bars on the storage racks, and transport roller conveyors enable chip bar transfer between different partitions. This system enables automatic and rapid circulation and online intelligent management of chip bars in different states and scenarios, improves the management and use efficiency of chip bars, reduces manual workload, and enhances the safety of chip bar use and management.
