Description

Technical Field

[0001] The present invention belongs to the technical field of transformer core manufacturing, and particularly relates to an automatic feeding system and method for transformer core columns. Background Art

[0002] In the existing production process of transformer cores, the single-table feeding method is mainly used for cross-cutting and feeding, and the waiting time of the cross-cutting line is relatively long. At the same time, the storage methods of core columns are mostly flat storage or automated storage. Among them, flat storage occupies a large area and is not conducive to improving the unit output value of the overall workshop; while using automated storage for sheet material feeding and storage saves storage space, but the unit cost is very high, and there are certain construction requirements for height, and it cannot be implemented in some low-rise workshops. Summary of the Invention

[0003] The present invention aims to solve the above problems and provides an automatic feeding system and method for transformer core columns, which can unload multiple core columns from the cross-cutting line at one time and realize the intelligent storage and scheduling of core column materials under the condition of limited space.

[0004] According to the technical solution of the present invention, the automatic feeding system for transformer core columns includes a blanking mechanism, a storage mechanism, a distribution mechanism, and a number of pallets. The pallets circulate between the blanking mechanism, the storage mechanism, and the distribution mechanism, and are used to carry core columns to form column materials (the column materials in the present invention include core columns and pallets carrying the core columns).

[0005] The blanking mechanism includes a pusher frame, Track I, and a blanking cart. The pusher frame is arranged at the discharge port of the cross-cutting mechanism. Track I is installed on the outlet side of a number of pusher frames. The blanking cart is slidably installed on Track I and is used to transfer column materials and pallets between the pusher frame and the distribution mechanism.

[0006] The storage mechanism is arranged at the outlet end of the blanking cart and includes a transition frame, a pallet rack, and a number of storage racks. The transition frame is used to transfer column materials to the distribution mechanism; the pallet rack is used to temporarily store empty pallets of the distribution mechanism and convey them to the blanking cart; the storage racks are used to temporarily store column materials.

[0007] The distribution mechanism includes Track II, a batching cart, a stockpiling cart, and a receiving cart. Track II is installed on one side of a number of lamination tables close to the distribution mechanism; the batching cart is slidably installed on Track II and is used to receive column materials from the storage mechanism; the stockpiling cart is slidably installed on Track III between adjacent lamination tables and is used to receive column materials from the batching cart and place empty pallets; the receiving cart is used to receive column materials from the stockpiling cart.

[0008] Further, the feeding rack, the blanking truck, the transition rack, the storage rack and the pallet rack are all 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. A driving member is arranged in each roller area for driving the rotation of the rollers in this area.

[0009] Further, a stop baffle is arranged at one end of the storage rack away from the blanking truck, and the stop baffle is a fixed structure or a movable structure.

[0010] Further, a movable stop bar is arranged at one end of the transition rack away from the blanking truck, and the movable stop bar is installed on a telescopic member.

[0011] Further, the batching truck is a liftable structure, including a lifting platform. At least two batching roller channels are installed on the lifting platform. Each batching roller channel includes at least two batching roller areas. A batching driving member is arranged in each batching roller area for driving the rotation of the rollers in this batching roller area.

[0012] Further, the stock preparation truck is a rotatable structure, including a rotating platform. A stock preparation roller bed and a pallet support are installed on the rotating platform, and the stock preparation roller bed includes several stock preparation roller channels.

[0013] Further, the number of the stock preparation roller channels is the same as the number of the core columns of a single transformer core. Heavy hammer stops are arranged at both ends of the stock preparation roller channels.

[0014] Further, the feeding rack, the blanking truck, the transition rack, the pallet rack, the storage rack and the batching truck are docked through laser ranging and positioning.

[0015] Further, a scheduling system is further included, and the scheduling system is used to control the operation of the blanking mechanism, the storage mechanism and the distribution mechanism.

[0016] On the other hand, the present invention provides a method for automatically feeding transformer core columns, which is realized based on the above-mentioned transformer core column automatic feeding system, and includes the following steps:

[0017] S1: During the warehousing operation, the blanking truck receives the column materials on the feeding rack and transfers them to the storage rack for temporary storage.

[0018] S2: During the discharging operation, the column materials on the storage rack or the feeding rack are transferred to the transition rack through the blanking truck, then transferred to the stock preparation truck through the batching truck, and finally delivered to the designated lamination table through the material receiving truck; after the core columns are laminated, the empty pallets are temporarily stored on the pallet rack and then transferred to the feeding rack through the blanking truck.

[0019] The technical solution of the present invention has the following advantages compared with the prior art:

Detailed implementation manners

[0034] The present invention will be 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 be able to implement it, but the specific embodiments cited are not intended to limit the present invention.

[0035] As Figure 1 shown, the present invention provides an automatic feeding system for a transformer core column, including a blanking mechanism, a storage mechanism, a distribution mechanism, and a plurality of pallets 11. Among them, the pallets 11 circulate between the blanking mechanism, the storage mechanism, and the distribution mechanism, and are used to carry the core columns 12 to form column materials.

[0036] The blanking mechanism includes a material feeding rack 1, a Track I 2, and a blanking cart 3. Among them, the material feeding rack 1 is arranged at the discharge port of the transverse shearing mechanism, and can receive the core sheets sheared by the transverse shearing mechanism by using the pallets 11, and the core sheets are stacked to form the core columns 12. The Track I 2 is installed on the outlet side of a plurality of material feeding racks 1, and the blanking cart 3 is slidably installed on the Track I 2. The blanking cart 3 slides along the Track I 2, so as to serve multiple transverse shearing mechanisms. The blanking cart 3 is used to realize the transfer of column materials and pallets 11 between the material feeding rack 1 and the distribution mechanism. Specifically, the blanking cart 3 can transfer the column materials on the material feeding 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 empty pallets 11 on the pallet rack 6 to the material feeding rack 1.

[0037] The storage mechanism is arranged at the outlet end of the blanking vehicle 3, and includes a transition rack 5, a pallet rack 6, and a number of storage racks 4. Among them, the transition rack 5 is used to transfer column materials to the distribution mechanism. The pallet rack 6 is used to temporarily store the empty pallets 11 of the distribution mechanism and convey them to the blanking vehicle 3, realizing the reverse conveyance of the empty pallets. The storage rack 4 is used to temporarily store column materials. When batching is required, the target column materials on the storage rack 4 are transferred to the transition rack 5 through the blanking vehicle 3 and then transferred to the distribution mechanism. It can be imagined that the target column materials on the storage rack 4 can also be directly transferred to the distribution mechanism without being transferred through the blanking vehicle 3 and the transition rack 5.

[0038] The distribution mechanism is arranged on the side of the storage mechanism away from the blanking mechanism, and includes a track II 7, a batching vehicle 8, a stock preparation vehicle 9, and a material receiving vehicle 10. Among them, the track II 7 is installed on the side of a number of lamination tables 13 close to the distribution mechanism. The batching vehicle 8 is slidably installed on the track II 7 and is used to receive the column materials in the storage mechanism. The batching vehicle 8 slides along the track II 7, so that column material distribution can be carried out for a number of lamination tables 13. The stock preparation vehicle 9 is used to receive the column materials on the batching vehicle 8 and place empty pallets 11. The material receiving vehicle 10 is used to receive the column materials on the stock preparation vehicle 9. According to the number of core columns of the transformer core, each lamination table 13 is configured with a number of material receiving vehicles 10, and each material receiving vehicle 10 distributes one column material. To reduce the walking distance of the material receiving vehicle 10 and facilitate the material receiving vehicle 10 to receive the column materials on the stock preparation vehicle 9, a track III 14 can be arranged between adjacent lamination tables 13, and the stock preparation vehicle 9 is slidably installed on the track III 14.

[0039] In some preferred embodiments, the material punching rack 1, the blanking vehicle 3, the transition rack 5, the storage rack 4, and the pallet rack 6 are all 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 as to unload multiple core columns from the horizontal shearing line at one time and realize the intelligent storage and scheduling of column materials 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 rollers in this area, so as to accurately control the conveyance of each column material.

[0040] As Figure 2As shown, in one embodiment, the blanking truck 3 includes a support frame 3.1 with a double-layer structure. Track wheels 3.2 are installed at the bottom of the support frame 3.1. The rotation of the track wheels 3.2 drives the blanking truck 3 to slide along the track I 2. The rotation of the track wheels 3.2 can be driven by a motor or other mechanisms. Two layers of blanking roller beds 3.3 are installed on the support frame 3.1. Each layer of the blanking roller bed 3.3 includes 4 blanking roller tube channels. Each blanking roller tube channel includes 3 blanking roller tube areas. One blanking driving motor (not shown in the figure) is provided in each blanking roller tube area to drive the rotation of the rollers in that area, thereby driving the column materials or pallets 11 in and out of the blanking truck 3. An operation console 3.4 can also be provided on one side of the support frame 3.1 to manually control or automatically control the rotation of the track wheels 3.2 and / or the operation of each blanking driving motor.

[0041] The storage rack 4 is fixed to the ground, as Figure 3 As 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 tube channels. Each upper storage roller tube channel includes 2 roller areas, which are arranged on the side close to the blanking truck 3. The lower storage roller bed 4.3 includes 4 lower storage roller tube channels. Each lower storage roller tube channel includes 3 roller areas. A stop baffle 4.1 is provided on the side of the upper storage roller bed 4.2 and the lower storage roller bed 4.3 away from the blanking truck 3. The stop baffle 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 materials from slipping; the stop baffle 4.1 can also be a movable structure. For example, one end of the stop baffle 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 structure. When the column materials need to be transferred out from this end, the stop baffle 4.1 is rotated and removed.

[0042] The transition rack 5 is fixed to the ground, as Figure 4 As shown, in one embodiment, the transition rack 5 includes a frame structure and upper and lower layers of transition roller beds 5.3 installed thereon. Each layer of the transition roller bed 5.3 includes 4 transition roller tube channels. Each transition roller tube channel includes 3 transition roller tube areas. A movable stop bar 5.1 is provided at one end of the transition rack 5 away from the blanking truck 3. The movable stop bar 5.1 is installed on a telescopic member 5.2. The telescopic member 5.2 can adopt a cylinder, and the piston rod of the cylinder expands and contracts to control whether the movable stop bar 5.1 blocks the column materials on the transition roller bed 5.3.

[0043] As Figure 5 As shown, in one embodiment, the pallet rack 6 includes upper and lower layers of pallet roller beds 6.1. Each layer of the pallet roller bed 6.1 includes 2 pallet roller tube channels. Each transition roller tube channel includes 2 pallet roller tube areas.

[0044] The batching truck 8 has a liftable structure, asFigure 6 As shown in the figure, in one embodiment, the batching cart 8 includes a lifting platform 8.1, and the lifting platform 8.1 is driven to lift by a motor or an electric cylinder, etc. 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 the batching roller channels 8.2 includes two batching roller areas, and the other batching roller channel 8.2 includes three batching roller areas. A batching driving member 8.3, such as a driving motor, is arranged in each batching roller area for driving the rotation of the rollers in this batching roller area. Through the lifting of the lifting platform 8.1, the batching roller channels 8.2 can be respectively docked with the upper and lower two-layer transition roller beds 5.3, or respectively docked with the upper-layer storage roller bed 4.2, the lower-layer storage roller bed 4.3 and the stock preparation roller bed 9.2.

[0045] The stock preparation cart 9 has a rotatable structure, such as Figure 7 As shown in the figure, in one embodiment, the stock preparation cart 9 includes a rotating platform 9.1. A stock preparation track wheel 9.5 is installed on the rotating platform 9.1, and a stock preparation roller bed 9.2 and a pallet support 9.3 are installed on the rotating platform 9.1. Among them, the stock preparation roller bed 9.2 includes a number of stock preparation roller channels. In some preferred embodiments, to conveniently complete all column materials of the transformer core at one time, the number of stock preparation roller channels is the same as the number of core columns of a single transformer core. Taking a three-phase three-column transformer core as an example, the core columns include an upper yoke, a lower yoke, a middle column and two side columns. Therefore, the stock preparation roller bed 9.2 includes five stock preparation roller channels. Heavy hammer stops 9.4 are also arranged at both ends of the stock preparation roller channels to prevent the column materials from sliding out.

[0046] Such as Figure 8 As shown in the figure, in one embodiment, the material receiving cart 10 includes a material receiving cart frame 10.1. A roller 10.3 is installed at the bottom of the material receiving cart frame 10.1, and a single non-powered material receiving roller channel 10.2 is installed on the material receiving cart frame 10.1. The height of the material receiving roller channel 10.2 is the same as the height of the stock preparation roller bed 9.2 in the stock preparation cart 9.

[0047] In some preferred embodiments, the feeding frame 1, the blanking cart 3, the transition frame 5, the pallet frame 6, the storage frame 4 and the batching cart 8 are docked through laser ranging and positioning, with a high degree of automation and capable of providing high-precision distance measurement, ensuring the docking accuracy.

[0048] In some preferred embodiments, a scheduling system is further included, such as an MDS scheduling system (multimedia scheduling system) for controlling the operation of the blanking mechanism, the storage mechanism and the distribution mechanism to achieve a high degree of automation.

[0049] Based on the above transformer core column automatic feeding system, the present invention also provides a transformer core column automatic feeding method, including the following steps:

[0050] S1: During the warehousing operation, the blanking vehicle 3 receives the column materials on the feeding rack 1 and transfers them to the storage rack 4 for temporary storage.

[0051] S2: During the discharging operation, the target column materials on the storage rack 4 or the feeding rack 1 are transferred to the transition rack 5 by the blanking vehicle 3, then transferred to the stock preparation vehicle 9 by the batching vehicle 8, and finally delivered to the periphery of the designated lamination table 13 by the material receiving vehicle 10. After the lamination of the target iron core column 12 is completed, the empty pallet 11 is placed on the pallet rack 9.3 of the stock preparation vehicle 9, then transferred to the pallet rack 6 by the batching vehicle 8 for temporary storage, and when receiving a new production instruction, it is transferred to the feeding rack 1 by the blanking vehicle 3.

[0052] Taking the three-phase three-column transformer core as an example, during the feeding operation, after the horizontal shearing mechanism finishes feeding, the blanking vehicle 3 docks with the feeding rack 1, and can store 5 groups of column materials at a time, divided into upper and lower layers. The column materials are arranged as Figure 9 shown. Two 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 in corresponding positions, and the corresponding columns (blanking roller channels) of the upper and lower layers are combined into 1 whole transformer core. After receiving the column materials, the blanking vehicle 3 moves along the track I 2 to the designated storage rack 4 and transfers the column materials to the storage rack 4 in the same arrangement. Compared with the traditional buffer 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.

[0053] During the discharging operation, the blanking vehicle 3 transfers the target column materials on the storage rack 4 to the transition rack 5. The batching vehicle 8 receives all the target column materials by lifting and docking with the two-layer roller beds of the transition rack 5 respectively, and then transfers all of them to the stock preparation vehicle 9. The stock preparation vehicle 9 rotates 90°, and conveys the 5 column materials on it to 5 material receiving vehicles 10 respectively. The material receiving vehicle 10 moves to the periphery of the lamination table 13 for lamination. After the lamination is completed, the empty pallet 11 is placed on the stock preparation vehicle 9 and then transferred to the pallet rack 6. Multiple pallets 11 can be stacked together and can be conveyed to the feeding rack 1 by the blanking vehicle 3 according to requirements.

[0054] 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 at the horizontal shearing line when the warehousing is required, and trigger the discharging application when discharging.

[0055] It can be imagined that the target column materials can be directly transferred from the feeding rack 1 by the blanking vehicle 3; the target column materials on the storage rack 4 can be directly conveyed to the batching vehicle 8 without the need for the blanking vehicle 3 and the transition rack 5 for transfer; when the number of iron core columns of the transformer core is different, the corresponding structure can be adjusted.

[0056] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill 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 enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
