Description

Technical Field

[0001] This invention relates to the field of metallurgical rolling mill equipment, specifically to a coil unloading device and a coil unloading method. Background Technology

[0002] Typically, the unloading device is located at the end of the P&F (hook conveyor) line on high-speed wire rod or large coil production lines. It unloads the packaged and weighed coils from the C-hooks of the P&F line and systematically stacks them onto coil storage racks, awaiting crane removal. Finished coils are lifted using either double-fork coil hooks or disc cranes. Double-fork coil hooks have two lifting booms at the bottom, allowing for the lifting of two rows of coils at once, improving lifting efficiency.

[0003] When using a double-fork coil hoist for lifting, the existing coil unloading device employs a two-channel (A and B) coil storage rack with a lateral movement mechanism to coordinate with the hook operation. The existing coil unloading method is as follows: The centerline of the unloading trolley is first aligned with the centerline of the A-channel coil storage rack. Upon arrival of a coil, the unloading trolley lifts it from the C-hook on the P&F line and transports it to the A-channel coil storage rack for sequential storage. After three coils are stored on the A-channel rack, the lateral movement mechanism below the rack moves laterally, aligning the centerline of the B-channel coil storage rack with the centerline of the unloading trolley. Subsequent arriving coils are then stored on the B-channel rack. After three coils are stored on the B-channel rack, the double-fork coil hoist lifts the coils from both the A and B channels in one operation.

[0004] The above information can be found in Chinese Invention Patent CN 101941027 A, published on January 12, 2011, entitled "A Method for Unwinding and Aligning Qualified Finished Wire Coils of High-Speed ​​Wire". Or in Chinese Invention Patent CN 106040781 A, published on October 26, entitled "A Control Method for Unwinding Wire Coils".

[0005] Existing coil unloading methods have the following problems: 1. High requirements for electrical control, which can easily lead to production accidents. The traverse mechanism needs to align the centers of the A-channel and B-channel coil storage racks sequentially with the centerline of the unloading trolley. If a deviation occurs, the unloading trolley cannot pass smoothly through the junction point, causing a production accident. 2. Insufficient structural strength of the equipment. The unloading trolley must travel between the coil storage racks, and the design of the coil storage racks must consider the height and width space required for the trolley's movement. Therefore, the coil storage racks are high, there cannot be crossbeams between the two sides of the coil storage racks, and the coil storage racks are thin, sheet-like structures with poor rigidity, making them prone to deformation after a period of use. Summary of the Invention

[0006] To address the issue of deviations that can easily occur when the unloading trolley enters channel A or channel B, this invention provides a coil unloading device and a coil unloading method. In this coil unloading device, the unloading trolley only needs to enter one of the first channel (corresponding to channel A) or the second channel (corresponding to channel B). Then, the transfer mechanism can move the coil from the first storage position to the second storage position, eliminating the need for the transverse movement mechanism of the coil storage rack and avoiding the alignment control problem between the transverse movement mechanism and the unloading trolley.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a coil unloading device, including an unloading trolley, a transfer mechanism and a storage rack. The storage rack has a first channel and a second channel arranged side by side. The storage rack is provided with a first storage position and a second storage position. The first storage position corresponds to the first channel and the second storage position corresponds to the second channel. The unloading trolley corresponds to the first channel and can only move along the first channel. The unloading trolley can only unload the coil to the first storage position. The transfer mechanism can move the coil at the first storage position to the second storage position.

[0008] The coil unloading device includes multiple coil transfer mechanisms, and the coil storage rack is provided with multiple first storage positions and multiple second storage positions. Along the left and right direction, the coil transfer mechanisms, the first storage positions and the second storage positions are arranged in a one-to-one correspondence.

[0009] The rewinding mechanism can touch the reel and roll it laterally from the first storage position to the second storage position.

[0010] The transfer mechanism includes a material-pulling arm, a hydraulic cylinder, and a mounting base connected in sequence. The transfer mechanism is located on the left side of the first channel, and the material-pulling arm can move the coil in the first storage position.

[0011] The storage rack contains left-side supports, middle supports, and right-side supports arranged at intervals from left to right, and the left-side supports, middle supports, and right-side supports are parallel to each other.

[0012] The first channel is located between the left support and the middle support, and the second channel is located between the middle support and the right support.

[0013] Along the extension direction of the first channel, the left support has multiple left support segments, and there is a gap between two adjacent left support segments. The material feeding arm corresponds to the gap and can pass through the gap.

[0014] The transfer mechanism includes a pusher plate, a hydraulic cylinder, and a mounting base connected in sequence. The transfer mechanism is located on the left side of the first channel, and the pusher plate can push the coil in the first storage position.

[0015] A method for unwinding a coil, wherein the method employs the aforementioned coil unwinding device, and the method includes the following steps:

[0016] Step 1: Unload the coil onto the unloading trolley;

[0017] Step 2: The unloading trolley unloads the coil into the first storage position of the coil storage rack;

[0018] Step 3: The transfer mechanism moves the coil from the first storage position to the second storage position.

[0019] The coil unloading device includes three coil transfer mechanisms. The coil storage rack is provided with three first storage positions and three second storage positions. Along the extension direction of the first channel, the three coil transfer mechanisms are, in sequence, the first coil transfer mechanism, the second coil transfer mechanism, and the third coil transfer mechanism. The three first storage positions are, in sequence, the first storage position, the second storage position, and the third storage position. The three second storage positions are, in sequence, the second storage position, the second storage position, and the third storage position.

[0020] In step 2, the unloading trolley unloads the first coil into the first storage position.

[0021] In step 3, the first reel transfer mechanism moves the first reel in the first storage position to the second storage position.

[0022] The coil unwinding method further includes the following steps:

[0023] Step 4: The unloading trolley unloads the second coil into the No. 2, first storage position;

[0024] Step 5: The second reel transfer mechanism moves the second reel from the first storage position to the second storage position.

[0025] Step 6: The unloading trolley unloads the third coil into storage position number 3, position 1;

[0026] Step 7: The No. 3 transfer mechanism moves the third coil from the No. 3 first storage position to the No. 3 second storage position;

[0027] Step 8: The unloading trolley unloads the fourth coil to storage position 1, the unloading trolley unloads the fifth coil to storage position 2, and the unloading trolley unloads the sixth coil to storage position 3.

[0028] The beneficial effects of the present invention are:

[0029] 1. A rewinding mechanism is adopted, which has low requirements for electrical control. The rewinding mechanism can move the coil to the B-channel rewind rack simply by raising the material-shifting arm. The transverse movement mechanism of the rewind rack is eliminated, avoiding the centering control problem between the transverse movement mechanism and the unloading trolley.

[0030] 2. The track of the unloading trolley can be arranged continuously, which reduces the accident points at the track junctions and makes the unloading trolley run reliably and smoothly.

[0031] 3. The equipment has a simple structure and good rigidity. The roll storage rack is directly fixed to the foundation, which greatly reduces the height and improves the rigidity of the equipment. Attached Figure Description

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] A coil unloading device includes an unloading trolley 1, a transfer mechanism 2, and a storage rack 3. The storage rack 3 has a first channel 31 and a second channel 32 arranged side by side. The storage rack 3 has a first storage position 33 and a second storage position 34. The first storage position 33 corresponds to the first channel 31, and the second storage position 34 corresponds to the second channel 32. The unloading trolley 1 corresponds to the first channel 31 and can only move along the first channel 31. The unloading trolley 1 can only unload coils 5 onto the first storage position 33. The transfer mechanism 2 can move the coils 5 from the first storage position 33 to the second storage position 34. Figures 1 to 5 As shown.

[0048] The first channel 31 and the second channel 32 are arranged parallel to each other. The first channel 31 is equivalent to channel A in the prior art, and the second channel 32 is equivalent to channel B in the prior art. The unloading trolley 1 can only move along the first channel 31 at the position corresponding to the first channel 31, and the unloading trolley 1 cannot move along the second channel 32 at the position corresponding to the second channel 32. The transfer mechanism 2 can make the coil 5 on the first storage position 33 slide or roll to the second storage position 34.

[0049] In this embodiment, the coil unloading device may include one or more transfer mechanisms 2, and the storage rack 3 may have multiple first storage positions 33 and multiple second storage positions 34. The number of transfer mechanisms 2, the number of first storage positions 33, and the number of second storage positions 34 are the same, and the transfer mechanisms 2, the first storage positions 33, and the second storage positions 34 are arranged in a one-to-one correspondence along the left-right direction. For example, the coil unloading device may include three transfer mechanisms 2, and the storage rack 3 may have three first storage positions 33 and three second storage positions 34, such as... Figure 1 and Figure 2 As shown.

[0050] In this embodiment, the transfer mechanism 2 can contact the coil 5 to provide an upward force to the coil 5, causing the coil 5 on the first storage position 33 to roll laterally to the right to the second storage position 34. The transfer mechanism 2 includes a feeding arm 21, a hydraulic cylinder 22, and a mounting base 23 connected in sequence. The transfer mechanism 2 is located on the left side of the first channel 31, and the feeding arm 21 can move the coil 5 on the first storage position 33.

[0051] Specifically, the hydraulic cylinder 22 is roughly horizontal, and the feeding arm 21 is roughly an inclined elongated structure. The left end of the hydraulic cylinder 22 is hinged to the mounting base 23, and the right end of the hydraulic cylinder 22 is hinged to the middle of the feeding arm 21. The right end of the feeding arm 21 is connected to the feeding arm shaft 28, the axis of which is parallel to the extension direction along the first channel 31. The left end of the feeding arm 21 is located inside the first channel 31 and below the coil 5. The hydraulic cylinder 22 extends, thereby providing an upward force to the coil 5 at the right end of the feeding arm 21, and causing the coil 5 in the first storage position 33 to roll to the right to the second storage position 34. Figures 3 to 5 As shown.

[0052] In this embodiment, the storage rack 3 includes a left-side support 35, a middle support 36, and a right-side support 37 arranged from left to right at intervals, and the left-side support 35, the middle support 36, and the right-side support 37 are parallel to each other. The first storage position 33 is located on the left-side support 35 and the middle support 36, and the second storage position 34 is located on the middle support 36 and the right-side support 37. The first storage position 33 and the second storage position 34 share the middle support 36, which can save one support.

[0053] In this embodiment, the first channel 31 is located between the left support 35 and the middle support 36, and the second channel 32 is located between the middle support 36 and the right support 37. The first channel 31, the second channel 32, the left support 35, the middle support 36, and the right support 37 are parallel to each other. The left support 35, the middle support 36, and the right support 37 are all fixed to the concrete foundation with anchor bolts.

[0054] In this embodiment, along the extending direction of the first channel 31, the left support 35 includes multiple left support segments 351, and a gap 352 is provided between two adjacent left support segments 351. The position of the feeding arm 21 corresponds to the gap 352, and the feeding arm 21 can pass through the gap 352. For example, the left support 35 includes four left support segments 351 and three gaps 352.

[0055] In this embodiment, a trolley travel groove and a trolley track 4 are provided below the first channel 31. The trolley track 4 is located within the trolley travel groove. The first channel 31 and the trolley track 4 are arranged vertically parallel to each other. The unloading trolley 1 is located on the trolley track 4 and can move back and forth along the trolley track 4, that is, the unloading trolley 1 can move forward and backward. Figure 3 As shown. During the process of moving the coil 5 from the first storage position 33 to the second storage position 34, rubber pads can be installed on the intermediate support 36 and the right support 37 to prevent damage to the surface of the coil 5.

[0056] The transfer mechanism 2 can also be implemented in another way. For example, the transfer mechanism 2 includes a pusher plate 24, a hydraulic cylinder 22, and a mounting base 23 connected in sequence. The transfer mechanism 2 is located on the left side of the first channel 31. The pusher plate 24 is a vertical plate that can push the coil 5 on the first storage position 33. The hydraulic cylinder 22 extends, thereby causing the pusher plate 24 to provide a rightward force to the coil 5, pushing the coil 5 on the first storage position 33 to roll to the right to the second storage position 34, as shown. Figure 6 As shown.

[0057] The main inventive point of the coil unloading device of the present invention is that it reduces the two trolley tracks 4 in the prior art to one, eliminates the transverse movement mechanism used to move the unloading trolley 1 between the two trolley tracks 4, and adds a transfer mechanism 2. The unloading trolley 1 can only move along the first channel 31, and can only unload the coil 5 onto the first storage position 33. The transfer mechanism 2 moves the coil 5 from the first storage position 33 to the second storage position 34, and then the unloading trolley 1 unloads the coil 5 back onto the first storage position 33, so that the coil 5 exists at both the first storage position 33 and the second storage position 34.

[0058] The following describes a method for unwinding coiled coils. This method utilizes the aforementioned coil unwinding device and includes the following steps: Figure 1 and Figure 7 As shown:

[0059] Step 1: Unload coil 5 onto unloading trolley 1; that is, unload coil 5 from the C-hook 7 of P&F line 6 and place it on unloading trolley 1.

[0060] Step 2: The unloading trolley 1 unloads the coil 5 onto the first storage position 33 of the coil storage rack 3;

[0061] Step 3: The transfer mechanism 2 moves the coil 5 on the first storage position 33 to the second storage position 34.

[0062] For example, the coil unloading device includes three coil transfer mechanisms 2, and the coil storage rack 3 is provided with three first storage positions 33 and three second storage positions 34. Along the extension direction of the first channel 31, the three coil transfer mechanisms 2 are successively the first coil transfer mechanism 25, the second coil transfer mechanism 26 and the third coil transfer mechanism 27, the three first storage positions 33 are successively the first first storage position 331, the second first storage position 332 and the third first storage position 333, and the three second storage positions 34 are successively the first second storage position 341, the second second storage position 342 and the third second storage position 343.

[0063] The first roll transfer mechanism 25 is located to the left of the first storage position 331, and the first second storage position 341 is located to the right of the first storage position 331. The second roll transfer mechanism 26 is located to the left of the second first storage position 332, and the second second storage position 342 is located to the right of the second first storage position 332. The third roll transfer mechanism 27 is located to the left of the third first storage position 333, and the third second storage position 343 is located to the right of the third first storage position 333. Along the reverse extension of the first channel 31, the first first storage position 331, the second first storage position 332, and the third first storage position 333 are arranged sequentially.

[0064] Specifically, the coil unwinding method includes the following steps:

[0065] Step 1: The unloading trolley 1 is located below the C-hook 7 of the P&F line 6. The C-hook 7 of the P&F line 6 unloads the first coil 5 onto the unloading trolley 1.

[0066] Step 2: The unloading trolley 1 moves along the first channel 31 toward the direction of the storage rack 3, and the unloading trolley 1 unloads the first coil 5 onto the first storage position 331 of the storage rack 3.

[0067] Step 3: The unloading trolley 1 moves along the first channel 31 toward the direction of the P&F line 6. The C-hook 7 of the P&F line 6 unloads the second coil 5 onto the unloading trolley 1. The first transfer mechanism 25 moves the first coil 5 from the first storage position 331 to the second storage position 341.

[0068] Step 4: The unloading trolley 1 moves along the first channel 31 toward the direction of the storage rack 3, and the unloading trolley 1 unloads the second coil 5 onto the second first storage position 332;

[0069] Step 5: The unloading trolley 1 moves along the first channel 31 toward the direction of the P&F line 6. The C-hook 7 of the P&F line 6 unloads the third coil 5 onto the unloading trolley 1. The second transfer mechanism 26 moves the second coil 5 from the second first storage position 332 to the second second storage position 342.

[0070] Step 6: The unloading trolley 1 moves along the first channel 31 toward the direction of the storage rack 3, and the unloading trolley 1 unloads the third coil 5 onto the third first storage position 333.

[0071] Step 7: The unloading trolley 1 moves along the first channel 31 toward the direction close to the P&F line 6. The C-hook 7 of the P&F line 6 unloads the fourth coil 5 onto the unloading trolley 1. The third transfer mechanism 27 moves the third coil 5 from the third first storage position 333 to the third second storage position 343.

[0072] Step 8: The unloading trolley 1 moves along the first channel 31 toward the direction of the storage rack 3, and the unloading trolley 1 unloads the fourth coil 5 onto the first storage position 331.

[0073] The unloading trolley 1 moves along the first channel 31 toward the direction close to the P&F line 6. The C-hook 7 of the P&F line 6 unloads the fifth coil 5 onto the unloading trolley 1. The unloading trolley 1 moves along the first channel 31 toward the direction close to the storage rack 3. The unloading trolley 1 unloads the fifth coil 5 onto the second first storage position 332.

[0074] The unloading trolley 1 moves along the first channel 31 toward the direction of the P&F line 6. The C-hook 7 of the P&F line 6 unloads the sixth coil 5 onto the unloading trolley 1. The unloading trolley 1 moves along the first channel 31 toward the direction of the storage rack 3. The unloading trolley 1 unloads the sixth coil 5 onto the third first storage position 333.

[0075] Step 9: The double-fork coil hook lifts all six coils (the first, second, third, fourth, fifth, and sixth coils mentioned above) from the storage rack 3 in one go.
