Description

Technical Field

[0001] The present invention relates to the field of electrical steel storage equipment and technology, in particular to a stacker for automatically storing and retrieving single or multiple horizontal steel coils of core column raw material steel coils. Background Art

[0002] In the prior art, electrical steel coils are usually picked up, placed and transported by crane. This operation will mainly cause the following problems:

[0003] First: When operators use the crane to take out electrical steel coils in the material warehouse, other materials, required materials and cantilever racks are prone to collision, which may cause the edges of the electrical steel coils to be damaged or the cantilever racks to be deformed;

[0004] Second, when taking and placing narrow steel coils (such as electrical steel coils with a sheet width of 30mm), due to the small sheet width, such steel coils are prone to shaking during the lifting process, resulting in tipping, which poses a serious safety hazard;

[0005] Third, when the cantilever rack is higher than the height of a person, it is difficult for operators to take and place single or multiple rolls of materials from the rack;

[0006] Fourth, when transporting multiple rolls of materials, the operator needs to transport them one by one by the crane. Due to the slow speed of the crane, the transport time is too long and the transport efficiency is extremely low, which increases unnecessary working hours and increases the company's labor costs. Summary of the invention

[0007] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a stacker for automatically storing and retrieving single or multiple horizontal steel coils of core column raw material steel coils, so that single or multiple electrical steel coils can be automatically, efficiently and quickly retrieved and transported from a stereoscopic warehouse.

[0034] The structure of the lifting vehicle 33 is as follows: it includes a lifting vehicle frame 16, a lifting vehicle fixed pulley 19 is installed at the bottom of the lifting vehicle frame 16, a large gear 21 is installed in the lifting vehicle frame 16 through a support block 29, the large gear 21 is driven to rotate by a small gear and a motor, a fork turntable 20 is fixedly installed on the top surface of the large gear 21, a groove 22 is provided in the middle of the fork turntable 20, the groove 22 is connected to the support 30 through a sliding mechanism 18, and the forks located on both sides of the groove 22 Guide rails 32 are symmetrically mounted on the turntable 20, rollers 31 are mounted on both sides of the bottom of the support 30, and the rollers 31 slide along the guide rails 32. A fork arm 24 extends outward from the upper part of the support 30, and a plurality of fork supports 25 are installed at intervals on both sides of the fork arm 24. Polyurethane rods 27 are installed at the heads of the plurality of fork supports 25 at the same time. A plurality of cylinders 26 are fixed at intervals on the fork arm 24, and the output end of the cylinder 26 is connected to the fork support 25 to drive the fork support 25 to expand and retract.

[0035] The fork arm 24 and the support 30 are installed at 90 degrees.

[0036] The fork arm 24 extends into the inner hole of the electrical steel 23 , and the polyurethane rod 27 contacts the inner hole of the electrical steel 23 .

[0037] A lighting system 14 is installed at an inner position of the top surface of the lifting vehicle frame 16 , a monitoring camera 15 is installed at an upper portion of the inner wall surface of the lifting vehicle frame 16 , and a detection device 17 is installed inside the lifting vehicle frame 16 .

[0038] A fall prevention system 28 is mounted on the exterior of the lift truck frame 16 .

[0039] The sliding mechanism 18 adopts a gear rack mechanism or a screw mechanism.

[0040] An inspection ladder 10 is installed on the outer side of the main beam 4 , a bottom control platform 7 is installed at the lower part of the inspection ladder 10 , and a control cabinet 8 is installed on the bottom control platform 7 ; a top inspection platform 9 is installed at the upper part of the inspection ladder 10 .

[0041] The cable 13 is provided with a hook for fastening a safety buckle.

[0042] The frame structure of the present invention is provided with an inspection ladder 10; a steel wire rope to which a safety buckle can be fastened is installed on the side of the inspection ladder 10, providing a repair channel for maintenance personnel when the stacker fails.

[0043] The frame structure can identify obstacles during its movement. When the frame structure is running on the track, if the sensor installed on the frame structure (not shown in the figure) detects an obstacle in its direction of movement, the stacker will stop running immediately.

[0044] The frame structure is equipped with a top-level maintenance platform 9, which is convenient for maintenance personnel to repair equipment on the top level of the frame;

[0045] The lifting vehicle is equipped with an anti-falling system 28; when the cable 13 driving the lifting vehicle 33 to lift and lower is separated from the lifting vehicle fixed pulley 19 below the lifting vehicle 33, the lifting vehicle 33 is mechanically locked on the track.

[0046] The lifting vehicle 33 is equipped with a lighting system 14 and a monitoring camera 15, so that the warehouse manager can monitor the status of the stacker in real time.

[0047] The fork arm 24 is used to pick up and place materials on the shelves on both sides of the three-dimensional warehouse. The stacker fork arm 24 picks up and places materials from the inside of the electrical steel 23, and picks up and places the electrical steel 23 on the shelves on both sides of the three-dimensional warehouse by rotating the fork turntable 20.

[0048] During actual use, the frame structure can move along the top rail 1 and the bottom rail 2 under the action of the frame drive motor 11. During the movement of the frame structure, the detection machines (not shown in the figure) installed on both sides of the frame structure can automatically detect whether there are obstacles in the moving direction of the frame structure. If the detection machine detects an obstacle, the stacker stops moving. The warehouse manager enters the stereoscopic warehouse in time to remove the obstacle. Ensure that the frame structure does not collide with any object during operation. The maintenance ladder 10 on the frame structure is convenient for mechanics to climb up for maintenance work. There is a steel wire rope on the side of the maintenance ladder 10 that can be tied with a safety buckle. When the mechanic climbs the maintenance ladder 10, he wears safety equipment and ties the safety equipment to the safety buckle to ensure the safety of high-altitude operations. The control cabinet 8 of the bottom control platform 7 is convenient for the warehouse manager to manually control the movement of the stacker. The top maintenance platform 9 is convenient for mechanics to repair equipment.

[0049] The lifting car 33 realizes the retraction and release of the cable 13 wound in the cable storage drum through the lifting car driving motor 12. These cables 13 lift the lifting car fixed pulley 19, thereby causing the lifting car 33 to move up and down along the inner track of the stacker main beam 4. The lifting car 33 is equipped with a safety anti-fall system 28. When the cable 13 driving the lifting car 33 to lift and lower is separated from the lifting car fixed pulley 19 below the lifting car 33, the lifting car 33 mechanically locks it on the track. The lifting car 33 is equipped with a lighting system 14 and a monitoring camera 15, which is convenient for the warehouse manager to monitor the status of the stacker in real time outside the three-dimensional warehouse. The detection devices 17 on both sides of the lifting car 33 are used to realize whether the electrical steel 23 is completely placed on the shelf of the three-dimensional warehouse or on the stacker fork arm 24 when the stacker fork arm 24 takes out the electrical steel 23. If there is electrical steel 23 that is not completely placed on the stacker fork arm 24 or on the shelf of the three-dimensional warehouse, the detection device 17 automatically detects the exposed electrical steel 23 and the stacker stops running.

[0050] The fork arm 24 is a cantilever beam structure, which takes and places materials from the inner side of the electrical steel 23. The electrical steel 23 on the shelves on both sides of the three-dimensional warehouse is taken and placed by rotating the fork turntable 20 of the stacker, so that the electrical steel 23 can be taken from both sides of the fork of the cantilever structure. The sliding mechanism 18 drives the support 30 and the fork arm 24 to move forward or backward along the guide rail 32 at the same time. The detector (not shown in the figure) configured at the front end of the fork arm 24 can automatically detect whether the electrical steel 23 is placed on the shelf of the three-dimensional warehouse, and can identify whether the shelf can continue to place electrical steel 23. When the fork arm 24 extends into the inner side of the electrical steel 23 hanging on the shelf of the three-dimensional warehouse, the detector (not shown in the figure) installed at the end of the fork arm 24 can automatically calculate the number of electrical steels 23. When a number of electrical steels 23 are placed on the fork arm 24 of the stacker, a detection device (not shown in the figure) arranged on the cylinder 26 connected to the fork support 25 detects the rising position of the fork support 25 to determine whether the inner circle of the electrical steel 23 is deformed.

[0051] The specific process of stacker reclaiming is as follows:

[0052] The frame structure and the lifting vehicle 33 move to the shelf position of the three-dimensional warehouse, and the fork turntable 20 rotates so that the fork arm 24 faces the shelf where the material is to be taken. The fork arm 24 enters the inner side of the electrical steel 23. Further, the frame structure rises. Further, the cylinder 26 works, and the fork support 25 opens to support the inner circle of the electrical steel 23. Further, the fork arm 24 returns to the origin.

[0053] The specific process of stacker unloading is as follows:

[0054] The frame structure and the lifting vehicle 33 move to the shelf position of the three-dimensional warehouse, and the fork turntable 20 rotates so that the fork arm 24 faces the shelf where the material is to be placed. Further, the frame structure descends. Further, the fork support 25 shrinks, and the fork arm 24 returns to the origin.

[0055] A detection instrument that can identify the electrical steel 23 is installed on the upper rear of the fork arm 24. The detection instrument can detect whether there is electrical steel 23 on the fork arm 24. At the same time, during the process of taking out the electrical steel 23, the detection instrument can also identify whether the electrical steel 23 on the fork arm 24 is offset. If the offset is too large, the stacker stops running.
