Description

Technical Field

[0001] This utility model relates to the field of aluminum coil conveying technology, specifically to an aluminum coil loading and unloading device. Background Technology

[0002] Aluminum coils are metal products produced by casting and rolling mills after rolling, bending, and straightening, and are then ready for flying shearing. An uncoiler uncoils the aluminum coil according to requirements and removes the defective ends (the parts that do not meet quality standards). The uncoiler then rewinds the remaining portion of the aluminum coil to form a qualified finished aluminum coil. During the production process of aluminum coils, due to their large weight, manual loading and unloading is time-consuming, labor-intensive, and inefficient. Therefore, there is an urgent need for an aluminum coil loading and unloading device to solve these problems. Utility Model Content

[0003] To address the problem of time-consuming, labor-intensive, and inefficient manual loading and unloading of aluminum coils during the production process of aluminum coils using uncoilers, this invention provides an aluminum coil loading and unloading device that automates the loading and unloading of aluminum coils, improving loading and unloading efficiency, reducing human workload, and thus accelerating aluminum coil production efficiency.

[0004] This utility model provides an aluminum coil loading and unloading device, including a loading component, an unloading component, a moving trolley, and a pallet. The loading component and the unloading component are arranged side by side on the working ground, and the moving trolley is movably arranged on the working ground. The moving trolley is located below the loading component and the unloading component, and the moving direction of the moving trolley is perpendicular to the length direction of the loading component and the unloading component. The pallet is placed on the loading component, and the moving trolley is used to transfer the pallet from the loading component to the unloading component.

[0005] Furthermore, the feeding assembly includes a first feeding frame, a second feeding frame, and multiple first feeding rollers and second feeding rollers. The first and second feeding frames are positioned on the working ground, with a first gap between them. The moving trolley is located below the first gap. The multiple first feeding rollers are evenly rotated and positioned on the first feeding frame, and the multiple second feeding rollers are evenly rotated and positioned on the second feeding frame. The multiple first and second feeding rollers contact or separate from the bottom of the pallet. When part of the pallet passes through the first gap to the second feeding roller, the first and second feeding rollers jointly support the pallet and the semi-finished aluminum coil. The rotation of the multiple first and second feeding rollers conveys the pallet and the semi-finished aluminum coil.

[0006] Furthermore, each of the first and second feeding rollers is equipped with a first feeding wheel and a second feeding wheel at both ends. The second feeding wheel has a first annular groove. The wheel surfaces of the multiple first feeding rollers and the first annular grooves on the second feeding wheels contact or separate from the bottom of the pallet. When the multiple first and second feeding rollers rotate, the pallet is actually supported and transported by the first feeding wheels and the second feeding wheels; and the first annular groove can limit the position of the pallet and prevent the pallet from shifting.

[0007] Furthermore, the feeding assembly includes a first feeding frame, a second feeding frame, and multiple first feeding rollers and second feeding rollers. The first and second feeding frames are positioned on the working ground, with a second gap between them. The moving trolley is located below the second gap. The multiple first feeding rollers are evenly rotated and positioned on the first feeding frame, and the multiple second feeding rollers are evenly rotated and positioned on the second feeding frame. The multiple first and second feeding rollers contact or separate from the bottom of the pallet. When the moving trolley moves below the second gap, it places the pallet and the finished aluminum coil on the first and second feeding rollers. At this time, the first and second feeding rollers jointly support the pallet and the finished aluminum coil. The rotation of the multiple first feeding rollers and second feeding rollers conveys the pallet and the finished aluminum coil.

[0008] Furthermore, each of the first and second feeding rollers is equipped with a first feeding wheel and a second feeding wheel at both ends. The second feeding wheel has a second annular groove. The wheel surfaces of the multiple first feeding rollers and the second annular grooves on the second feeding wheels contact or separate from the bottom of the pallet. When the multiple first and second feeding rollers rotate, the pallet is actually supported and transported by the first and second feeding wheels; and the second annular grooves can restrict the position of the pallet and prevent the pallet from shifting.

[0009] Furthermore, a hydraulic cylinder and a slide rail are fixedly installed on the mobile trolley. The hydraulic rod of the hydraulic cylinder is fixedly connected to the top head. A sliding plate is slidably mounted on the slide rail and is fixedly connected to the top head. A slot is provided on the pallet, and the top head is engaged in the slot, with the top head located at the first notch on the feeding assembly or the second notch on the unloading assembly. When the hydraulic cylinder is activated, it drives the top head to move upward or downward, while the sliding plate moves up and down along the slide rail, causing the top head to engage or disengage from the slot. The slide rail and sliding plate, together with the hydraulic cylinder and the top head, support the pallet, further stabilizing it.

[0010] Furthermore, two tracks are positioned opposite each other on the working surface, located below the loading and unloading components. The length direction of the tracks is perpendicular to the length direction of the loading and unloading components. Two driving wheels and a driven wheel are evenly rotatably mounted on the moving trolley, both positioned evenly within the two tracks and capable of movement. The rotation of the driving and driven wheels allows them to move within the tracks, enabling the moving trolley to move along the length direction of the tracks.

[0011] Furthermore, the tray has two symmetrically arranged brackets at an angle, with a gap between them. At least one support roller is fixedly mounted on the top of each bracket. Semi-finished or finished aluminum coils are placed on the support rollers of the two brackets, which support and fix them in place.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model discloses an aluminum coil loading and unloading device. A pallet holds semi-finished aluminum coils. The pallet and semi-finished coils are placed on a loading component, which then loads them onto the pallet. The loading component transports the pallet and semi-finished coils to a mobile trolley. The mobile trolley removes the pallet and semi-finished coils from the loading component and transports them to an external uncoiler. The external uncoiler removes the semi-finished aluminum coils and processes them, resulting in qualified finished aluminum coils. The external uncoiler returns the finished aluminum coils to the mobile trolley, which then transports the pallet and finished aluminum coils to an unloading component. The unloading component transports the pallet and finished aluminum coils and unloads them. Finally, the finished aluminum coils are transported to an external warehouse for storage. This aluminum coil loading and unloading device replaces manual loading and unloading of aluminum coils, achieving automated loading and unloading, improving loading and unloading efficiency, reducing labor intensity, and thus accelerating aluminum coil production efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, an aluminum coil loading and unloading device includes a loading component 1, an unloading component 2, a moving trolley 3, and a pallet 4. The loading component 1 and the unloading component 2 are arranged side by side on the working ground. The moving trolley 3 is movably arranged on the working ground. The moving trolley 3 is located below the loading component 1 and the unloading component 2, and the moving direction of the moving trolley 3 is perpendicular to the length direction of the loading component 1 and the unloading component 2. The pallet 4 is placed on the loading component 1. The moving trolley 3 is used to transfer the pallet 4 from the loading component 1 to the unloading component 2, that is, the moving trolley 3 is used to remove the pallet 4 from the loading component 1 and transport it to the unloading component 2.

[0024] The working process of the aluminum coil loading and unloading device is as follows: Pallet 4 is loaded with semi-finished aluminum coils. Pallet 4 and semi-finished aluminum coils are placed on loading component 1. Loading component 1 loads pallet 4 and semi-finished aluminum coils and transports them to the location of mobile trolley 3. Mobile trolley 3 removes pallet 4 and semi-finished aluminum coils from loading component 1 and transports them to the location of external uncoiler. External uncoiler removes the semi-finished aluminum coils and processes them. After processing, the semi-finished aluminum coils become qualified finished aluminum coils. External uncoiler returns the finished aluminum coils to mobile trolley 3. Then, mobile trolley 3 transports pallet 4 and finished aluminum coils to the location of unloading component 2. Unloading component 2 transports pallet 4 and finished aluminum coils and unloads them. Finally, the finished aluminum coils are transported to an external warehouse for finished product storage.

[0025] The aluminum coil loading and unloading device in this embodiment replaces manual loading and unloading of aluminum coils, realizing automatic loading and unloading of aluminum coils, improving the loading and unloading efficiency of aluminum coils, reducing the labor intensity of people, and thus accelerating the production efficiency of aluminum coils.

[0026] In one possible implementation, the feeding assembly 1 includes a first feeding frame 11, a second feeding frame 13, and a plurality of first feeding rollers 12 and second feeding rollers 14. The first feeding frame 11 and the second feeding frame 13 are set on the working ground and a first gap is left between the first feeding frame 11 and the second feeding frame 13. The moving trolley 3 is located below the first gap. The size of the first gap is smaller than the size of the tray 4. The plurality of first feeding rollers 12 are evenly rotated and arranged on the first feeding frame 11, and the plurality of second feeding rollers 14 are evenly rotated and arranged on the second feeding frame 13. The plurality of first feeding rollers 12 and second feeding rollers 14 are in contact with or separate from the bottom of the tray 4. Pallet 4 is loaded with semi-finished aluminum coils. Pallet 4 and the semi-finished aluminum coils are placed on multiple first feeding rollers 12. When part of pallet 4 passes through the first notch and reaches the second feeding roller 14, the first feeding rollers 12 and the second feeding roller 14 jointly support pallet 4 and the semi-finished aluminum coils. The rotation of the multiple first feeding rollers 12 and the second feeding roller 14 realizes the conveying of pallet 4 and semi-finished aluminum coils. The moving trolley 3 moves to below the first notch and performs the next operation on pallet 4 and semi-finished aluminum coils located at the first notch.

[0027] Preferably, a plurality of feeding bearing seats are evenly arranged on the first feeding frame 11 and the second feeding frame 13, and the two ends of the first feeding roller 12 and the second feeding roller 14 are respectively fixedly connected to the feeding bearings of the two feeding bearing seats, thereby enabling the first feeding roller 12 and the second feeding roller 14 to rotate.

[0028] Preferably, first double-toothed sprockets 17 are fixedly mounted on the first feeding roller 12 and the second feeding roller 14. A first chain is sleeved between the first double-toothed sprockets 17 of adjacent first feeding rollers 12 and between the first double-toothed sprockets 17 of adjacent second feeding rollers 14. Feeding motors 6 are fixedly mounted on both the first feeding frame 11 and the second feeding frame 13. The output shaft of one feeding motor 6 is fixedly connected to one of the first feeding rollers 12 via a reducer, and the output shaft of the other feeding motor 6 is fixedly connected to one of the second feeding rollers 14 via a reducer. When one feeding motor 6 starts, it drives the first feeding roller 12 to rotate, causing the multiple first double-toothed sprockets 17 and the first chain to rotate, ultimately driving the multiple first feeding rollers 12 to rotate. Similarly, when the other feeding motor 6 starts, it drives the second feeding roller 14 to rotate, causing the multiple first double-toothed sprockets 17 and the first chain to rotate, ultimately driving the multiple second feeding rollers 14 to rotate.

[0029] Multiple first feeding frames 11 can be set (the number of first feeding rollers 12 set on multiple first feeding frames 11 can be different). Multiple first feeding frames 11 are located on the same side of the second feeding frame 13. The purpose of setting multiple first feeding frames 11 is to extend the feeding area of ​​the pallet 4 and the semi-finished aluminum coil, and to further facilitate the feeding of the pallet 4 and the semi-finished aluminum coil.

[0030] In one possible implementation, each of the first feeding rollers 12 and 14 has a first feeding wheel 15 and a second feeding wheel 16 at both ends. The second feeding wheel 16 has a first annular groove. The wheel surfaces of the multiple first feeding rollers 15 and the first annular grooves on the second feeding wheel 16 contact or separate from the bottom of the pallet 4. When the multiple first feeding rollers 12 and 14 rotate, the pallet 4 is actually supported and transported by the first feeding wheels 15 and 16; and the first annular groove can limit the position of the pallet 4 and prevent the pallet 4 from shifting.

[0031] In one possible implementation, the feeding assembly 2 includes a first feeding frame 21, a second feeding frame 23, and a plurality of first feeding rollers 22 and second feeding rollers 24. The first feeding frame 21 and the second feeding frame 23 are set on the working ground, and a second gap is left between the first feeding frame 21 and the second feeding frame 23. The size of the first gap is smaller than the size of the tray 4. The moving trolley 3 is located below the second gap. The plurality of first feeding rollers 22 are evenly rotated and set on the first feeding frame 21, and the plurality of second feeding rollers 24 are evenly rotated and set on the second feeding frame 23. The plurality of first feeding rollers 22 and second feeding rollers 24 are in contact with or separate from the bottom of the tray 4. The pallet 4 is loaded with finished aluminum coils. The moving trolley 3 transports the pallet 4 and the finished aluminum coils. When the moving trolley 3 moves to below the second notch, it places the pallet 4 and the finished aluminum coils on the first feeding roller 22 and the second feeding roller 24. At this time, the first feeding roller 22 and the second feeding roller 24 jointly support the pallet 4 and the finished aluminum coils. The rotation of multiple first feeding rollers 12 and second feeding rollers 24 realizes the transport of the pallet 4 and the finished aluminum coils.

[0032] Preferably, a plurality of feeding bearing seats are evenly arranged on the first feeding frame 21 and the second feeding frame 23, and the two ends of the first feeding roller 22 and the second feeding roller 24 are respectively fixedly connected to the feeding bearings of the two feeding bearing seats, thereby enabling the first feeding roller 22 and the second feeding roller 24 to rotate.

[0033] Preferably, second double-toothed sprockets 27 are fixedly mounted on the first feeding roller 22 and the second feeding roller 24. Second chains are fitted between the second double-toothed sprockets 27 of adjacent first feeding rollers 22 and between the second double-toothed sprockets 27 of adjacent second feeding rollers 24. Feeding motors 7 are fixedly mounted on both the first feeding frame 21 and the second feeding frame 23. The output shaft of one feeding motor 7 is fixedly connected to one of the first feeding rollers 22 via a reducer, and the output shaft of the other feeding motor 7 is fixedly connected to one of the second feeding rollers 24 via a reducer. When one feeding motor 7 is started, it drives the first feeding roller 22 to rotate, causing multiple second double-toothed sprockets 27 and the second chain to rotate, ultimately driving multiple first feeding rollers 22 to rotate. Similarly, when the other feeding motor 7 is started, it drives the second feeding roller 24 to rotate, causing multiple second double-toothed sprockets 27 and the second chain to rotate, ultimately driving multiple second feeding rollers 24 to rotate.

[0034] Multiple first feeding frames 21 can be set (the number of first feeding rollers 22 set on multiple first feeding frames 21 can be different). Multiple first feeding frames 21 are located on the same side of the second feeding frame 23. The purpose of setting multiple first feeding frames 21 is to extend the feeding area of ​​the pallet 4 and the finished aluminum coil, and to further facilitate the feeding of the pallet 4 and the finished aluminum coil.

[0035] In one possible implementation, each of the first feeding rollers 22 and the second feeding rollers 24 has a first feeding wheel 25 and a second feeding wheel 26 at both ends. The second feeding wheel 26 has a second annular groove. The wheel surfaces of the multiple first feeding rollers 25 and the second annular grooves on the second feeding wheel 26 are in contact with or separate from the bottom of the pallet 4. When the multiple first feeding rollers 22 and the second feeding rollers 24 rotate, the pallet 4 is actually supported and transported by the first feeding wheels 25 and the second feeding wheels 26; and the second annular groove can restrict the position of the pallet 4 and prevent the pallet 4 from shifting.

[0036] As one possible implementation, multiple support columns are evenly arranged on the first feeding frame 11, the second feeding frame 13, the first unloading frame 21 and the second unloading frame 23. The top of the support column contacts the bottom of the pallet 4, and the support column also supports the pallet 4 when the pallet 4 is being transported.

[0037] As one possible implementation method, combined with Figures 4-6 The mobile trolley 3 is fixedly equipped with a hydraulic cylinder 31 and a slide rail 32. The hydraulic rod of the hydraulic cylinder 31 is fixedly connected to the bottom of the top head 34. Preferably, the top head 34 is a cuboid. A sliding plate 33 is slidably mounted on the slide rail 32 (the sliding plate 33 is located on the slide rail 32 and can move up and down; the sliding method of the slide rail 32 and the sliding plate 33 is existing technology and will not be described in detail here). The sliding plate 33 is fixedly connected to the bottom of the top head 34. The tray 4 is provided with a slot. Preferably, the slot is elongated. The top of the top head 34 is inserted into the slot, and the top head 34 is located at the first notch on the feeding component 1 or the second notch on the unloading component 2. When the hydraulic cylinder 31 is activated, it drives the top head 34 to move up or down. At the same time, the sliding plate 33 moves up and down on the slide rail 32, causing the top head 34 to engage or disengage from the slot. The slide rail 32 and the sliding plate 33, together with the hydraulic cylinder 31 and the top head 34, support the tray 4, further stabilizing the tray 4. Once the mobile trolley 3 is fixedly connected to the pallet 4, the movement of the mobile trolley 3 will drive the pallet 4 and the semi-finished or finished aluminum coils to move.

[0038] In one possible implementation, two tracks 5 are positioned opposite each other on the working surface, located below the loading assembly 1 and the unloading assembly 2. The length direction of the tracks 5 is perpendicular to the length direction of the loading assembly 1 and the unloading assembly 2. Two driving wheels 35 and driven wheels 36 are evenly rotatably mounted on the moving trolley 3. The two driving wheels 35 and driven wheels 36 are evenly located within the two tracks 5 and are movable. The rotation of the driving wheels 35 and driven wheels 36 allows them to move within the tracks 5, thus enabling the moving trolley 3 to move along the length direction of the tracks 5.

[0039] Preferably, a first motor 8 is fixedly mounted on the mobile trolley 3. The output shaft of the first motor 8 is fixedly connected to the input end of a hollow shaft reducer. A drive shaft 351 is passed through the output end of the hollow shaft reducer. Two drive bearing seats are fixedly mounted on the mobile trolley 3. The two ends of the drive shaft 351 pass through the drive bearings on the two drive bearing seats and are fixedly connected to two drive wheels 35. A driven shaft 361 is rotatably mounted on the mobile trolley 3. Two driven bearing seats are fixedly mounted on the mobile trolley 3. The two ends of the driven shaft 361 pass through the driven bearings on the two driven bearing seats and are fixedly connected to two driven wheels 36. When the first motor 8 is started, it drives the drive shaft 351 and the two drive wheels 35 to rotate. The driven shaft 361 and the two driven wheels 36 also rotate, and finally the mobile trolley 3 moves along the length of the track 5.

[0040] Furthermore, a cable chain is movably installed on the working surface. The structure and movement of the cable chain are existing technologies and will not be described in detail here. When the mobile trolley 3 moves, the cable chain facilitates the movement of the wiring harness of components such as the first motor 8.

[0041] As one possible implementation method, combined with Figures 4-5 , Figure 4 The structure of tray 4 can be seen. Two brackets 41 are symmetrically arranged on tray 4, and the two brackets 41 are inclined. A gap is provided between the two brackets 41. At least one support roller 42 is fixedly installed on the top of each bracket 41. Semi-finished or finished aluminum coils are placed on the support rollers 42 of the two brackets 41, and the two support rollers 42 support and fix them. Preferably, the top of the bracket 41 is provided with two support rollers 42, which are arranged sequentially along the length of the bracket 41. The top of the bracket 41 has two grooves with pin holes. Roller shafts are provided at both ends of the support rollers 42. The roller shafts pass through the pin holes and are locked to the bracket 41 by nuts, thus fixing the support rollers 42 to the bracket 41.

[0042] The working process of the aluminum coil loading and unloading device is as follows: A pallet 4 is placed on multiple first loading rollers 12, and semi-finished aluminum coils are placed on multiple support rollers 42 of the pallet 4. The rotation of the multiple first loading rollers 12 conveys the pallet 4 and the semi-finished aluminum coils. When part of the pallet 4 passes through the first notch and reaches the second loading roller 14, the first and second loading rollers 12 and 14 jointly convey the pallet 4 and the semi-finished aluminum coils. The moving trolley 3 moves below the first notch, and the hydraulic cylinder 31 is activated, driving the top head 34 to move upward and the slide plate 33 to move upward in the slide rail 32. The top head 34 engages in the slot of the pallet 4, fixing the pallet 4 onto the moving trolley 3. The moving trolley 3 then conveys the pallet 4 and the semi-finished aluminum coils. The moving trolley 3 moves forward in the track 5 to the location of the external uncoiler, where the external uncoiler removes the semi-finished aluminum coils and processes them. The coils are processed, and after the semi-finished aluminum coils are processed, they become qualified finished aluminum coils. The external uncoiler sends the finished aluminum coils back to the tray 4 of the moving trolley 3. The moving trolley 3 moves backward in the track 5, driving the tray 4 and the finished aluminum coils to move below the second notch. The hydraulic cylinder 31 is activated, driving the top head 34 to move downward and the slide plate 33 to move downward in the slide rail 32. At this time, the first feeding roller 22 and the second feeding roller 24 jointly support the tray 4 and the finished aluminum coils. The top head 34 finally leaves the slot of the tray 4. The first feeding roller 22 and the second feeding roller 24 rotate to realize the conveying of the tray 4 and the finished aluminum coils. When the tray 4 and the finished aluminum coils have passed through the second notch and entered the first feeding roller 22, the first feeding roller 22 conveys the tray 4 and the finished aluminum coils. The first feeding roller 22 completes the unloading of the tray 4 and the finished aluminum coils.
