DETAILED DESCRIPTION
[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0026] like Figure 1 As shown, the present invention provides an automatic feeding system for transformer core columns, including a feeding mechanism, a storage mechanism, a delivery mechanism and a plurality of pallets 11. The pallets 11 circulate among the feeding mechanism, the storage mechanism and the delivery mechanism, and are used to carry the core columns 12 to form column materials.
[0027] The unloading mechanism includes a material rack 1, a track 12 and a material unloading vehicle 3. The material rack 1 is arranged at the discharge port of the transverse shearing mechanism, and can use a pallet 11 to receive the iron core sheets cut out by the transverse shearing mechanism, and the iron core sheets are stacked to form an iron core column 12. The track 12 is installed on the exit side of several material racks 1, and the material unloading vehicle 3 is slidably installed on the track 12. The material unloading vehicle 3 slides along the track 12 to serve multiple transverse shearing mechanisms. The material unloading vehicle 3 is used to realize the transfer of column materials and pallets 11 between the material rack 1 and the distribution mechanism. Specifically, the material unloading vehicle 3 can transfer the column materials on the material rack 1 to the storage rack 4 or the transition rack 5, or transfer the column materials on the storage rack 4 to the transition rack 5, or transfer the pallet 11 on the pallet rack 6 to the material rack 1.
[0028] The storage mechanism is arranged at the exit end of the unloading vehicle 3, and includes a transition rack 5, a pallet rack 6 and a plurality of storage racks 4. Among them, the transition rack 5 is used to transfer the column material to the distribution mechanism. The pallet rack 6 is used to temporarily store the hollow pallets 11 in the distribution mechanism and transfer them to the unloading vehicle 3, so as to realize the reverse conveyance of the empty pallets. The storage rack 4 is used to temporarily store the column material. When batching is required, the target column material on the storage rack 4 is transferred to the transition rack 5 through the unloading vehicle 3, and then transferred to the distribution mechanism. It is conceivable that the target column material on the storage rack 4 can also be directly transferred to the distribution mechanism without the need for transfer through the unloading vehicle 3 and the transition rack 5.
[0029] The distribution mechanism is arranged on the side of the storage mechanism away from the unloading mechanism, and includes a track II 7, a batching car 8, a material preparation car 9 and a material receiving car 10. Among them, the track II 7 is installed on the side of several stacking platforms 13 close to the distribution mechanism, and the batching car 8 is slidably installed on the track II 7, which is used to receive the column materials in the storage mechanism. The batching car 8 slides along the track II 7, so that the column materials can be distributed to multiple stacking platforms 13. The material preparation car 9 is used to receive the column materials on the batching car 8 and place an empty pallet 11, and the material receiving car 10 is used to receive the column materials on the material preparation car 9. According to the number of core columns of the transformer core, each stacking platform 13 is equipped with multiple material receiving cars 10, and each material receiving car 10 distributes one column material. In order to reduce the walking distance of the material receiving car 10 and facilitate the material receiving car 10 to receive the column materials on the material preparation car 9, a track III 14 can be set between adjacent stacking platforms 13, and the material preparation car 9 is slidably installed on the track III 14.
[0030] In some preferred embodiments, the material rack 1, the material unloading car 3, the transition rack 5, the storage rack 4 and the pallet rack 6 are all upper and lower two-layer roller bed structures, each layer of the roller bed includes at least two roller channels, and each roller channel includes at least two roller areas, so that multiple core columns can be unloaded from the cross-cutting line at one time, and the intelligent storage and scheduling of column materials can be realized under the condition of limited space. A driving member, such as a driving motor, is arranged in each roller area to drive the rotation of the roller in the area, so as to accurately control the delivery of each column material.
[0031] like Figure 2 As shown, in one embodiment, the unloading vehicle 3 includes a double-layer support frame 3.1, and a track wheel 3.2 is installed at the bottom of the support frame 3.1. The track wheel 3.2 rotates to drive the unloading vehicle 3 to slide along the track 12, and the rotation of the track wheel 3.2 can be driven by a motor or other mechanism. The support frame 3.1 is equipped with upper and lower layers of unloading roller beds 3.3, each layer of unloading roller beds 3.3 includes 4 unloading roller channels, each unloading roller channel includes 3 unloading roller areas, and each unloading roller area is provided with a unloading drive motor (not shown in the figure) for driving the rotation of the roller in the unloading roller area, thereby driving the column material or the pallet 11 to enter and exit the unloading vehicle 3. One side of the support frame 3.1 can also be provided with an operating table 3.4, which can manually or automatically control the rotation of the track wheel 3.2 and / or the operation of each unloading drive motor.
[0032] The storage rack 4 is fixed to the ground, such as Figure 3As shown, in one embodiment, the storage rack 4 includes a frame structure and an upper storage roller bed 4.2 and a lower storage roller bed 4.3 installed thereon, the upper storage roller bed 4.2 includes 4 upper storage roller channels, each of which includes 2 roller areas, and is arranged on a side close to the unloading vehicle 3. The lower storage roller bed 4.3 includes 4 lower storage roller channels, each of which includes 3 roller areas. A stopper plate 4.1 is arranged on the side of the upper storage roller bed 4.2 and the lower storage roller bed 4.3 away from the unloading vehicle 3. The stop plate 4.1 can be fixed at the ends of the upper storage roller bed 4.2 and the lower storage roller bed 4.3 to prevent the column material from slipping; the stop plate 4.1 can also be a movable structure, for example, one end of the stop plate 4.1 is fixed, and the other end is installed at the ends of the upper storage roller bed 4.2 and the lower storage roller bed 4.3 through a snap-on structure. When the column material needs to be transferred out from this end, the stop plate 4.1 is rotated to remove it.
[0033] The transition frame 5 is fixed to the ground. Figure 4 As shown, in one embodiment, the transition frame 5 includes a frame structure and two layers of transition roller beds 5.3 installed thereon, each layer of transition roller bed 5.3 includes four transition roller channels, and each transition roller channel includes three transition roller areas. A movable stopper 5.1 is provided at one end of the transition frame 5 away from the unloading vehicle 3, and the movable stopper 5.1 is installed on a telescopic member 5.2. The telescopic member 5.2 can be a cylinder, and the piston rod of the cylinder is telescopic, so as to control whether the movable stopper 5.1 blocks the column material on the transition roller bed 5.3.
[0034] like Figure 5 As shown, in one embodiment, the pallet frame 6 includes two upper and lower pallet roller beds 6.1, each pallet roller bed 6.1 includes two pallet roller channels, and each transition roller channel includes two pallet roller areas.
[0035] The batching vehicle 8 is a liftable structure. Figure 6 As shown, in one embodiment, the batching vehicle 8 includes a lifting platform 8.1, and the lifting platform 8.1 is driven to rise and fall by a motor or an electric cylinder. A batching track wheel 8.4 is installed at the bottom of the lifting platform 8.1, and two batching roller channels 8.2 are installed on the lifting platform 8.1, one of which includes two batching roller areas, and the other includes three batching roller areas. A batching drive 8.3 is provided in each batching roller area, such as a drive motor, for driving the rotation of the roller in the batching roller area. Through the lifting and lowering of the lifting platform 8.1, the batching roller channel 8.2 can be connected to the upper and lower transition roller beds 5.3 respectively, or to the upper storage roller bed 4.2 and the lower storage roller bed 4.3 and the preparation roller bed 9.2 respectively.
[0036] The material preparation vehicle 9 is a rotatable structure. Figure 7As shown, in one embodiment, the material preparation vehicle 9 includes a rotating table 9.1, on which a material preparation track wheel 9.5 is installed, and a material preparation roller bed 9.2 and a pallet bracket 9.3 are installed on the rotating table 9.1. Among them, the material preparation roller bed 9.2 includes a plurality of material preparation roller channels. In some preferred embodiments, in order to facilitate the one-time assembly of all column materials of the transformer core, the number of material preparation roller channels is consistent with the number of core columns of a single transformer core. Taking the three-phase three-column transformer core as an example, the core column includes an upper yoke, a lower yoke, a middle column and two side columns. Therefore, the material preparation roller bed 9.2 includes 5 material preparation roller channels. Heavy hammer stops 9.4 are also provided at both ends of the material preparation roller channels to prevent the column materials from slipping out.
[0037] like Figure 8 As shown, in one embodiment, the material receiving vehicle 10 includes a material receiving vehicle frame 10.1, a roller 10.3 is installed at the bottom of the material receiving vehicle frame 10.1, and a single unpowered material receiving roller channel 10.2 is installed on the material receiving vehicle frame 10.1, and the height of the material receiving roller channel 10.2 is consistent with the height of the material preparation roller bed 9.2 in the material preparation vehicle 9.
[0038] In some preferred embodiments, the material rack 1, the material unloading vehicle 3, the transition rack 5, the pallet rack 6, the storage rack 4 and the batching vehicle 8 are docked by laser ranging positioning, which has a high degree of automation and can provide high-precision distance measurement to ensure docking accuracy.
[0039] In some preferred embodiments, a dispatching system is also included, such as an MDS dispatching system (Multimedia Dispatching System), which is used to control the operation of the unloading mechanism, the storage mechanism and the distribution mechanism to achieve a high degree of automation.
[0040] Based on the above transformer core column automatic feeding system, the present invention also provides a transformer core column automatic feeding method, comprising the following steps: S1: During the warehousing operation, the unloading vehicle 3 receives the column material on the material rack 1 and transfers it to the storage rack 4 for temporary storage; S2: During the unloading operation, the target column material on the storage rack 4 or the material rack 1 is transferred to the transition rack 5 via the unloading trolley 3, and then transferred to the preparation trolley 9 via the batching trolley 8, and finally distributed to the designated stacking table 13 via the receiving trolley 10; after the stacking of the target core column 12 is completed, the empty pallet 11 is placed on the pallet rack 9.3 of the preparation trolley 9, and then transferred to the pallet rack 6 for temporary storage via the batching trolley 8. When a new production instruction is received, it is transferred to the material rack 1 via the unloading trolley 3.
[0041] Taking the three-phase three-column transformer core as an example, during the feeding operation, after the cross-shear mechanism completes the punching, the unloading car 3 is docked with the punching rack 1. Five groups of column materials can be stored at a time, divided into upper and lower layers. The column materials are arranged as follows: Fig. 9As shown, two sets of side columns are placed on the upper layer, and the upper yoke, lower yoke and middle column are placed on the lower layer. The upper and lower layers are corresponding positions, and the corresponding columns (unloading roller channels) of the upper and lower layers are combined into a complete transformer core. After the column material is received, the unloading vehicle 3 moves along the track I 2 to the designated storage rack 4, and transfers the column material to the storage rack 4 in the same arrangement. Compared with the traditional cache rack (storage rack), the storage rack 4 of the present invention can store all the column materials required for multiple transformer cores at one time, which is convenient for one-time transfer.
[0042] When discharging, the unloading car 3 transfers the target column material on the storage rack 4 to the transition rack 5, and the batching car 8 receives all the target column materials by lifting and docking the two layers of roller beds of the transition rack 5, and then transfers all of them to the preparation car 9. The preparation car 9 rotates 90 degrees and transports the five column materials on it to the five receiving cars 10 respectively. The receiving cars 10 move to the four sides of the stacking table 13 for stacking. After stacking, the empty pallet 11 is placed on the preparation car 9 and then transferred to the pallet rack 6. Multiple pallets 11 can be stacked together and can be transported to the material rack 1 by the unloading car 3 according to needs.
[0043] The docking, material receiving and transfer in the above operations can all be carried out under the scheduling logic set by the scheduling system. The staff only needs to trigger the warehousing application on the cross-cutting line when there is a demand for warehousing, and trigger the discharging application when discharging.
[0044] It is conceivable that the target column material can be directly transferred from the material rack 1 by the unloading vehicle 3; the target column material on the storage rack 4 can be directly transported to the batching vehicle 8 without the need for the unloading vehicle 3 and the transition rack 5 for transfer; when the number of core columns of the transformer core is different, the corresponding structure can be adjusted.
[0045] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
