[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] like Figure 1 As shown, the transfer device for galvanized steel coils includes a transport component 1, a lifting component 2, an unloading component 3, a rotating platform 4, a guide rail 5, and a first rail 6. The rotating platform 4 is located on the ground, with its upper surface flush with the ground. The guide rail 5 is located on the ground, and the first rail 6 is located on the rotating platform 4. The first rail 6 can connect with the guide rail 5. The transport component 1 is located on the guide rail 5 and can move along the guide rail 5. The lifting component 2 is located on the transport component 1, and the galvanized steel coil 7 is placed on the upper end of the lifting component 2. The unloading component 3 is installed on the lifting component 2 and is used to unload the galvanized steel coil 7.
[0033] like Figure 1 As shown, the guide rail 5 includes multiple sets of second rails 51, which are not parallel to each other, and each set of second rails 51 can connect with the first rail 6. Alternatively, the guide rail 5 may include two sets of second rails 51, which are perpendicular to each other, and each set of second rails 51 can connect with the first rail 6.
[0034] like Figure 2 As shown, the transport assembly 1 includes a power unit 11, a driven unit 12, a chassis 13, and an angle iron 14. The power unit 11 and the driven unit 12 are arranged parallel to each other and rotatably connected to both ends of the chassis 13. The periphery of the power unit 11 and the driven unit 12 are rotatably connected to the first track 6. The angle iron 14 is arranged around the chassis 13.
[0035] like Figure 2As shown, the power unit 11 includes two power rollers 111, a power wheel shaft 112, and a drive unit 113. The power wheel shaft 112 is rotatably connected to the chassis 13. The drive unit 113 is located at the upper end of the chassis 13, and the movable end of the drive unit 113 is fixedly connected to the power wheel shaft 112. One power roller 111 is fixedly connected to each end of the power wheel shaft 112. The outer periphery of the power roller 111 is rotatably connected to the first track 5. The driven unit 12 includes two driven rollers 121 and a driven roller shaft 122. The driven roller shaft 122 is rotatably connected to the chassis 13. Each driven roller 121 is connected to one end of the power wheel shaft 122. The outer periphery of the driven roller 121 is rotatably connected to the first track 5.
[0036] When transporting the galvanized steel coil 7, the controller is activated, sending a signal to the drive unit 113, which is an existing technology engine (model 1FW6). The drive unit 113 drives the power unit 11 to rotate. Both the power unit 11 and the driven unit 12 are mounted on the first track 6, allowing the transport assembly 1 to carry the galvanized steel coil 7 along the first track 6. Upon reaching the designated position, the controller sends a signal to the drive unit 113, which stops rotating, bringing the entire transport assembly 1 to a stop. This device, equipped with the transport assembly 1, automatically transports the galvanized steel coil 7 along the track to the appropriate position, replacing traditional manual transport by bridge cranes or freight trucks. This improves work efficiency, saves manpower, and enhances safety, ensuring production safety in the workshop.
[0037] like Figure 3As shown, the lifting assembly 2 includes a first hydraulic rod 21, a second hydraulic rod 22, a support plate 23, and two supports 24. The support plate 23 and the chassis 13 are arranged parallel to each other. The outer periphery of the four corners of the support plate 23 is slidably connected to the inner side of the corresponding angle iron 14. Four first hydraulic rods 21 are provided at the upper end of the chassis 13. The movable end of each first hydraulic rod 21 is connected to the lower end of the support plate 23. Two first square holes 231 are provided symmetrically on the support plate 23. A support 24 is slidably connected in each first square hole 231. Two second hydraulic rods 22 are also provided at the upper end of the chassis 13. The movable end of each second hydraulic rod 22 is connected to the lower end of a support 24. The galvanized steel coil 7 is placed on the upper end of the two supports 24. The first hydraulic rod 21 and the second hydraulic rod 22 are both prior art, and the model of the first hydraulic rod 21 and the second hydraulic rod 22 is DYTZ4000-650. When lifting is required, the controller raises the second hydraulic rod 22. The movable port of the second hydraulic rod 22 pushes the support 24 upward, which in turn pushes the galvanized steel coil 7 upward, thus achieving height control of the galvanized steel coil 7. The lifting assembly can raise the galvanized steel coil 7 to the required position without any mechanical contact or friction with the coil during the lifting process, maintaining a smooth and even zinc layer and enhancing product value.
[0038] like Figure 4 and Figure 5As shown, the unloading assembly 3 includes a V-shaped support plate 31, pulleys 32, two slide rails 33, a first metal plate 34, a lead screw 35, a second metal plate 36, and a rotary motor 37. Each slide rail 33 is arranged parallel to the lead screw 35, and the two slide rails 33 are installed on the upper end of the support plate 23. The support plate 23 is also provided with a second square hole 232, in which the first metal plate 34 is slidably connected. The upper end of the first metal plate 34 is fixedly connected to the V-shaped support plate 31. The pulleys 32 are rotatably connected around the V-shaped support plate 31. The pulleys 32 are rotatably connected to the slide rails 33 on the same side and move along the slide rails 33. The lead screw 35 is located below the support plate 23 and is threadedly connected to the lower end of the first metal plate 34. One end of the lead screw 35 is rotatably connected to the second metal plate 36, and the other end of the lead screw 35 is fixedly connected to the movable end of the rotary motor 37. The rotary motor 37 and the second metal plate 36 are both fixedly installed on the lower end of the support plate 23. When the steel coil is transported to the appropriate position, the controller sends a signal to the first hydraulic rod 21, and the support plate 23 is raised, transferring the support object of the steel coil from the support platform 24 to the V-shaped support plate 31 on the support plate 23. At this time, the controller sends a signal to the rotary motor 37. The rotary motor 37 is existing technology, and the model of the rotary motor 37 is Delta ASDA-H3. The movable port of the rotary motor 37 drives the lead screw 35 to rotate. Since the lead screw 35 is threaded to the first metal plate 34 and rotates to the second metal plate 36, and the second metal plate 36 is fixed to the lower end of the support plate 23, the rotation of the lead screw 35 will cause the first metal plate 34 to move in the second square hole 232. The first metal plate 34 will drive the V-shaped support plate 31 to move. Since the steel coil has a large mass, the pulleys 32 set around the V-shaped support plate 31 will roll along the slide rail 33, which can drive the heavy steel coil, allowing the V-shaped support plate 31 to carry the steel coil to the forklift. After the steel coil is moved to the forklift, the forklift moves and completely removes the steel coil from the device. At this time, the controller will control the first hydraulic rod 21 to retract, the support plate 23 to descend, and the rotating motor 37 will reverse, controlling the first metal plate 34 to move towards the device and driving the V-shaped support plate 31 back to its original position.
[0039] like Figure 6 and Figure 7As shown, the rotating platform 4 includes a rotating support plate 41 and a base. The upper end of the base is provided with a circular groove 42. A servo motor 43, a chain 44, a sprocket 45 and a rotating shaft 46 are arranged in the circular groove 42. The base 42 is installed in the foundation. One end of the rotating shaft 46 is rotatably connected to the bottom of the circular groove 42, and the other end of the rotating shaft 46 is fixedly connected to the lower end of the rotating support plate 41. The lower end of the rotating support plate 41 can be slidably connected to the upper end face of the side wall of the circular groove 42, and the upper end face of the rotating support plate 41 is flush with the end face of the foundation. A guide rail 5 is set on the upper end face of the support plate 41. A sprocket 45 is sleeved on the rotating shaft 46. A chain 44 is sleeved on the sprocket 45. The inner ring of the chain 44 meshes with the outer periphery of the output gear of the servo motor 43. The servo motor 43 is fixedly connected to the bottom of the circular groove 42.
[0040] like Figure 7 As shown, a reset switch 47 is also provided inside the rotating platform 4. The reset switch 47 includes an infrared transmitter 471 and a signal receiver 472. The infrared transmitter 471 is located on the lower end face of the rotating support plate 41, and the signal receiver 472 is located on the inner side wall of the circular groove 42.
[0041] Servo motor 43 is existing technology, model Beckhoff AL2800. Infrared transmitter 471 is existing technology, model FH4053. Signal receiver 472 is existing technology, model STSOP572. When a turn is required, the controller sends a signal to servo motor 43, causing the output gear of servo motor 43 to rotate. The output gear drives sprocket 45 synchronously via chain 44, simultaneously driving the rotating shaft 46 and the rotating support plate 41 fixed on it to rotate. After rotation, the rotating support plate 41 drives the transport component on it to rotate and change to the second track 51 in a different direction. By controlling the rotation speed of servo motor 43, it is ensured that the rotating support plate 41 has rotated to the appropriate angle and that the first track 6 and the corresponding guide track 5 can be connected. When the signal receiver 472 receives the infrared signal from infrared transmitter 471, it means that servo motor 43 has been reset, and this position is the rotation origin of servo motor 43. A rotating platform is installed, which allows steel coils to change direction and switch to different tracks without leaving the device, ensuring production continuity and improving work efficiency.
[0042] The working process of the transfer device for galvanized steel coils:
[0043] The steel coil is placed on the support platform 24. The controller is activated, sending a signal to the drive unit 113, which in turn drives the power unit 11 to rotate. Both the power unit 11 and the driven unit 12 are mounted on the track 5, allowing the transport assembly 1 to move along the track 5 carrying the galvanized steel coil 6. Upon reaching the designated position, the controller sends a signal to the drive unit 113, which stops rotating, bringing the entire transport assembly 1 to a stop. At this point, the controller controls the second hydraulic rod 22 to rise. The movable port of the second hydraulic rod 22 pushes the support platform 24 upward, which in turn pushes the galvanized steel coil 6 upward. After transporting the steel coil to the appropriate position, the controller sends a signal to the first hydraulic rod 21, which lifts and transfers the support platform 24 from the steel coil support platform 24 to the V-shaped support plate 31. At this point, the controller sends a signal to the rotary motor 37, whose movable port drives... When the lead screw 35 rotates, it causes the first metal plate 34 to move within the second square hole 232. The first metal plate 34 then moves the V-shaped support plate 31. The pulleys 32 surrounding the V-shaped support plate 31 roll along the slide rail 33, carrying a heavy steel coil. This allows the V-shaped support plate 31 to support the steel coil and move it onto the forklift. Once the steel coil is on the forklift, the forklift moves and completely removes the coil from the device. The controller then controls the first hydraulic rod 21 to retract, causing the support plate 23 to descend. Simultaneously, the rotating motor 37 reverses, controlling the first metal plate 34 to move towards the device and causing the V-shaped support plate 31 to reset. When the device needs to be turned, the controller sends a signal to the servo motor 43. The output gear of the servo motor 43 rotates, and the output gear drives the sprocket 45 synchronously via the chain 44. This drives the rotating shaft 46 and the rotating support plate 41 fixed on it to rotate. After rotation, the rotating support plate 41 drives the transport component 1 to rotate and change to a different direction of the guide rail 5. By controlling the rotation speed of the servo motor 43, it is ensured that the rotating support plate 41 has rotated to the appropriate angle and that the first track 6 and the corresponding guide track 5 can be connected. When the signal receiver 472 receives the infrared signal from the infrared transmitter 471, it means that the servo motor 43 has been reset. This position is the rotation origin of the servo motor 43.
[0044] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
