Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal coil loading technology, and more specifically, it relates to an intelligent loading device for metal coils, which can not only be used for loading metal coils, but also for unloading metal coils in certain situations. Background Technology
[0002] Currently, the specifications for heavy steel coils are: outer diameter 2000mm, inner diameter (approximately) 1200mm, width 1530mm, and weight 22-24 tons. Transporting these heavy steel coils presents a significant challenge, particularly determining the appropriate loading and unloading equipment.
[0003] To address the aforementioned issues, a search revealed Chinese patent CN118908112A, which discloses a forklift for transporting coiled steel. This forklift can transport different types of goods (including steel coils) and is convenient to use. Another example is Chinese patent CN108128734A, which discloses a heavy-duty steel coil handling vehicle that can easily load heavy steel coils into containers. Yet another example is Chinese patent CN112479087A, which discloses a lifting and loading device for a steel coil factory. This patent utilizes the extension and retraction of a telescopic rod to drive a sliding strip, with a short plate, adjusting rod, and grippers working together to clamp the steel coil. An electric adjusting screw prevents the steel coil from falling during the clamping process. For example, Chinese patent CN212403370U discloses a loading and unloading device suitable for copper and aluminum coil materials. The loading and unloading device includes a connecting rod, a front plate, and a hanging chain plate. Vertically arranged roller mounting plates are provided on the left and right sides of the rear side of the front plate, and a horizontally arranged hanging chain plate is provided between the two roller mounting plates. The hanging chain plate is connected to the lifting system of the trolley. Rollers are provided at the upper and lower ends of the outer sides of the two roller mounting plates. The rollers are in rolling contact with the U-shaped groove rails set on the opposite side of the trolley gantry. A connecting rod is provided on the center line of the front side of the front plate. The rear end of the connecting rod is fixedly connected to the front plate, and the front end of the connecting rod extends horizontally away from the front plate. Under the action of the lifting system, the hanging chain plate can move up and down relative to the gantry. The movement of the hanging chain plate drives the connecting rod to move up and down relative to the gantry. The connecting rod with the U-shaped structure is equivalent to surface contact with the drum.
[0004] Analysis of the aforementioned patents reveals that not only is security not guaranteed, but work efficiency also needs improvement. Summary of the Invention

Therefore, the scope of the present invention is defined only by the appended claims.
[0076] The following detailed description and exemplary embodiments of the present invention can be better understood in conjunction with the accompanying drawings, wherein the elements and features of the present invention are identified by reference numerals.

[0078] The aforementioned sensing component 22 is a 3D laser scanner (such as the commercially available KSCAN-Magic). The 3D laser scanner can obtain the cross-sectional dimensions, depth, and parking position of the container on the workstation, and then feed the relevant container data back to the control unit.

[0081] Furthermore, the guiding unit may also include at least one starting position 11 and multiple terminal positions 12. The multiple terminal positions 12 can correspond to various sizes of metal coils 50, such as widths of 0.8m, 1.2m, and 1.5m.

[0085] exist Figure 2 In this context, the transport device 40 is an RGV transport vehicle, which is a commercially available product, such as a HEGERLS intelligent RGV, and is located on the guide unit. The RGV transport vehicle can be linked with the sensing component 22 and the loading vehicle 30. The RGV transport vehicle can transport the metal roll 50 along the guide unit. After the loading vehicle 30 receives the metal roll 50, the RGV transport vehicle returns to receive the next metal roll 50. The RGV transport vehicle includes a vehicle body and a mounting bracket located on the vehicle body, and the metal roll 50 is placed on the mounting bracket.

The bottom of the lifting hydraulic cylinder 3154 is connected to the base 311 (hinged), and its telescopic rod is fixedly connected to the lifting arm 3151. A joint (heavy-duty cylinder configuration structure) is fitted at the front end of the telescopic arm. The height of the lifting arm 3151 is controlled by the stroke limiter of the lifting hydraulic cylinder 3154.

The Z-direction sensor 323 is mounted on the lifting arm 3151 and faces the connecting beam 3423. The X-direction sensor 321 is a laser rangefinder or a wire encoder; the Y-direction sensor 322 is a wire encoder; and the Z-direction sensor 323 is an ultrasonic displacement sensor.
[0090] Combination Figure 11 , Figure 12 , Figure 14 , Figure 15As shown, the actuator 34 includes a drive assembly 341, a support assembly 342, and a load-bearing assembly 343. The load-bearing assembly 343 includes a cantilever cylinder 3431 and an anti-collision device 3432. The anti-collision device 3432 includes at least one first distance sensor 34321 (e.g., the SL-5000 series laser displacement sensor commercially available from UKC) and at least one first displacement sensor 34322 (the ODT3CL1-2M diffuse reflection sensor commercially available from Leuze). The first distance sensor 34321 is located inside the cantilever cylinder 3431 and can detect the distance to obstacles in front in real time (when threading the roll, the obstacle is the metal roll 50; when feeding the roll, the obstacle is the container 21, which includes a container, a flatbed truck, or a train carriage. All of the above-mentioned container 21 have a plane, on which the metal roll 50 is stacked and then fixed by fasteners).
[0091] It should be noted that, in Figure 15 In this configuration, the first displacement sensor 34322 is installed on the top of the inner arc of the cantilever cylinder 3431. During the winding process, it detects the distance between the cantilever cylinder 3431 and the inner wall of the metal roll 50, thereby ensuring that the cantilever cylinder 3431 and the inner wall of the metal roll 50 are within a safe distance range and avoiding collision between the cantilever cylinder 3431 and the inner wall of the metal roll 50; and is used to trigger the measurement and verification of the width of the metal roll 50 during winding.
[0092] In addition, such as Figure 17 As shown, the anti-collision device 3432 also includes a pair of second distance sensors 34323, which are symmetrically arranged on the left and right sides of the base 34334. During loading, the left and right positions of the cantilever cylinder 3431 within the container 21 are detected. When the detection distance is less than a set value, for example, a set distance of 10mm, or a detection distance of 9.5mm, the corresponding value is triggered, and an alarm signal is issued.
[0093] Furthermore, such as Figure 17 As shown, the bearing assembly 343 further includes a buffer device 3433, which includes an anti-collision ring 34331, a connecting rod 34332, a spring 34333, and a base 34334. The anti-collision ring 34331 is fixed to the connecting rod 34332, and the spring 34333 is sleeved on the connecting rod 34332. The cylindrical base 34334 is connected to the end cap 34313 of the cantilever cylinder 3431. The bottom of the base 34334 has a through hole that allows the connecting rod 34332 to pass through. The spring 34333 is placed in the base 34334 and is limited by the end cap 34313. This structure design can effectively avoid rigid contact between the cantilever cylinder 3431 and the inner wall of the container 21.
[0094] In order to reduce the weight of the load-bearing component 343, Figure 15 In this design, the diameter of the anti-collision ring 34331 is consistent with the outer diameter of the cantilever cylinder 3431. The anti-collision ring 34331 has a plurality of relief holes 34337, and at least one of the relief holes 34337 corresponds to the first ranging sensor 34321, which can ensure that the first ranging sensor 34321 is not affected by the obstruction of the anti-collision ring 34331.
[0095] In this embodiment, the connecting rod 34332 is hollow, the anti-collision ring 34331 has a through hole in the center, a base plate 34335 is provided at the tail of the base 34334, the first ranging sensor 34321 is provided on the base plate 34335, and it can measure distance through the hollow part of the connecting rod 34332.
[0096] When the equipment of this utility model is applied to the container 21 with a box-like structure, such as Figure 15 As shown, the bearing assembly 343 also includes a safety monitoring device 3434. The safety monitoring device 3434 includes at least one tilt angle sensor 34341, at least one second displacement sensor 34342, and a 3D imaging camera 34343. The tilt angle sensor 34341 is located inside the cantilever cylinder 3431 and can detect the tilt angle of the cantilever cylinder 3431 during winding, preventing large tilt angle problems during overload. The second displacement sensor 34342 is located at the tilt angle... Above the degree sensor 34341 and installed on the top of the inner arc of the cantilever cylinder 3431, during unloading, the second displacement sensor 34342 detects the distance to the inner wall of the metal coil 50 and determines the timing for the cantilever cylinder 3431 to be pulled away, effectively ensuring that the cantilever cylinder 3431 is pulled away after the metal coil 50 is placed stably; the 3D imaging camera 34343 is installed on the end cover 34313, and its head extends out of the outside of the end cover 34313, which can perform 3D scanning of the environment at the front end of the cantilever cylinder 3431 to ensure safe loading.
[0097] In actual use, the cantilever cylinder 3431 will inevitably collide with the wall of the container 21. Figure 16 and Figure 17 In the buffer device 3433, a proximity switch 34336 is also included. The proximity switch 34336 is disposed on one side of the tail of the connecting rod 34332 and fixed on the base 34334. When the anti-collision ring 34331 contacts the inner wall of the container 21, the anti-collision ring 34331 can compress the spring 34333 and move towards the inside of the cantilever cylinder 3431. The connecting rod 34332 touches the proximity switch 34336, forcing the cantilever cylinder 3431 to stop moving.
[0098] In addition, such as Figure 15 As shown, a rubber sleeve 34311 is fitted on the outside of the cantilever cylinder 3431. The rubber sleeve 34311 wraps around the cantilever cylinder 3431, which not only prevents wear on the inner wall of the metal coil 50, but also prevents the metal coil 50 from wearing down the cantilever cylinder 3431.
[0099] like Figure 12 and Figure 14 As shown, the support assembly 342 includes a front suspension bracket 3421, a rear suspension bracket 3422, a connecting beam 3423, and a moving device 3424. The two ends of the connecting beam 3423 are respectively connected to the front suspension bracket 3421 and the rear suspension bracket 3422. The guide sleeve 3415 is fixed on the connecting beam 3423. The front suspension bracket 3421 and the rear suspension bracket 3422 are assembled with the cantilever cylinder 3431.
[0100] exist Figure 12 In this device, the moving device 3424 includes a front guide rail 34241, a front roller 34242, a fixed base 34243, a rear guide rail 34244, and a clamping wheel 34245. The front guide rail 34241 and the rear guide rail 34244 are respectively fixed on the lifting arm 3151. The front roller 34242 is mounted on the fixed base 34243 and placed on the front guide rail 34241. The front suspension bracket 3421 is connected and fixed to the fixed base 34243 and can move along the front guide rail 34241. The clamping wheel 34245 is mounted on the rear suspension bracket 3422 and cooperates with the rear guide rail 34244.
[0101] like Figure 12 As shown, a structure of the drive assembly 341 is presented, which includes a bidirectional drive servo motor 3411, a reducer 3412, a coupling 3413, a lead screw 3414, and a guide sleeve 3415. The bidirectional drive servo motor 3411, reducer 3412, and coupling 3413 are fixed on the lifting arm 3151, and the lead screw 3414 cooperates with the guide sleeve 3415. Driven by the bidirectional drive servo motor 3411, reducer 3412, and coupling 3413, the lead screw 3414 rotates, causing relative movement between the lead screw 3414 and the guide sleeve 3415. The guide sleeve 3415 carries the support assembly 342 and moves along the X direction.
[0102] The cooperation between the lead screw 3414 and the guide sleeve 3415 ensures high precision in the Z direction. At the same time, the cooperation between the double lead screw 3414 and the guide sleeve 3415 makes the movement of the cantilever cylinder 3431 smoother and more precise.
[0103] For the structure of the drive component 341 described above, some existing high-precision components, such as electro-hydraulic cylinders, can also be used.
[0104] In addition, to reduce the impact of external dust on the lead screw and guide sleeve, such as Figure 2 As shown, the drive assembly is also equipped with a protective cover 3416; the protective cover is fixed on the lifting arm, and the protective cover has ventilation holes, which can dissipate the heat generated inside the bidirectional drive servo motor and prevent the bidirectional drive servo motor from overheating.
[0105] Furthermore, such as Figure 15 As shown, the cantilever cylinder 3431 has a built-in cable conduit 34312. The wiring harnesses of the first distance sensor 34321, the first displacement sensor 34322, the second distance sensor 34323, the proximity switch 34336, the second displacement sensor 34342, the tilt angle sensor 34341, and the 3D imaging camera 34343 all pass through the cable conduit 34312 and are connected to the control system of the loading vehicle 30.
[0106] Combination Figure 15 As shown, the center lines of the first displacement sensor 34322, the second displacement sensor 34342, and the tilt angle sensor 34341 are located in the same vertical plane as the central axis of the cantilever cylinder 3431.
[0107] The first displacement sensor 34322 is one of a laser sensor, a diffuse reflection sensor, and an ultrasonic sensor; the second displacement sensor 34342 is one of a laser sensor, a diffuse reflection sensor, and an ultrasonic sensor; the first ranging sensor 34321 is one of a laser sensor, a diffuse reflection sensor, and an ultrasonic sensor; and the second ranging sensor 34323 is one of a laser sensor, a diffuse reflection sensor, and an ultrasonic sensor.
[0108] like Figure 2 and Figure 8 As shown, one embodiment is provided, wherein the walking mechanism 33 includes a reduction motor 331, a pair of drive wheels 332 connected to the reduction motor 331, and at least a pair of driven wheels 333; the drive wheels 332 and driven wheels 333 are respectively placed on the guide unit and can move along the direction of the guide unit. Mechanical limit plates are provided at the starting position 11 and the end position 12 of the transverse guide rail 10 to further limit the movement.

Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
