Description

Technical Field

[0001] This application relates to the technical field of hoisting and handling, and in particular to a handling device and method based on a ceiling rail vehicle. Background Technology

[0002] To reduce storage space, folded cardboard boxes are usually stacked vertically on clamping pallets. To make the stacked cardboard boxes easier to handle, they need to be bundled and packaged to prevent them from scattering during transport.

[0003] The packed cardboard boxes will be unpacked again later due to the quantity required for distribution. For example, if half a stack of cardboard boxes is needed, the packed cardboard boxes not only need to be bundled and packed in advance during transportation, but also interfere with the subsequent distribution. Therefore, there is an urgent need for a handling device that can stably transport the whole stack without packing. Summary of the Invention

[0018] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0019] This application discloses a transport device based on a skyrail vehicle. Example 1:

[0020] Reference Figure 1 A transport device based on a skyrail vehicle includes a transport platform 1, a drive assembly 2, and a support assembly 3.

[0021] The moving platform 1 is rectangular and horizontally positioned. The moving platform 1 is connected to the overhead rail car via a belt. The overhead rail car is used to drive the moving platform 1 to move horizontally and lift vertically.

[0022] A moving arm 11 and a protective arm 12 are slidably arranged on the bottom surface of the moving platform 1. There are two sets of moving arms 11 and protective arms 12 symmetrically arranged. Each set of moving arms 11 and protective arms 12 has two. The moving arm 11 is used to approach the side of the board, and the protective arm 12 is used to approach the side of the board. In this embodiment, the board is a cardboard box.

[0023] Reference Figure 2The drive assembly 2 is mounted on the moving platform 1 and is connected to all the moving arms 11 and guard arms 12. The drive assembly 2 is used to drive the moving arms 11 and guard arms 12 to slide so that the moving arms 11 and guard arms 12 can move closer to or away from the stacked plates.

[0024] Two sets of support components 3 are symmetrically arranged and connected to two sets of moving arms 11 respectively. The support components 3 are used to support the bottom of the stacked plates and to abut against the side of each plate. The support components 3 can support each plate in the stack.

[0025] In use, the lifting arm 11 and the protective arm 12 can surround the stacked panels, making it difficult for the stacked and unbundled panels to fall apart. The supporting component 3 can support the bottom of the stacked panels and provide support for the sides of each panel. When the railcar drives the lifting platform 1 to lift, the supporting component 3 can lift the stacked panels as a whole. Under the blocking effect of the protective arm 12, the stacked and unbundled panels are difficult to fall apart, so that the whole stack of panels can be transported stably without the need for packaging and bundling, and the panels are less likely to affect subsequent distribution after transportation.

[0026] Specifically, refer to Figure 1 The support assembly 3 includes a support plate 31 and a support roller 32.

[0027] The support plate 31 is located at the bottom end of the moving arm 11 and is fixedly connected to all the corresponding moving arms 11. The support roller 32 is rotatably connected to the support plate 31 and is used to abut against the side of each plate.

[0028] The support roller 32 can move with the moving arm 11 via the support plate 31. When the moving arm 11 is lifted along with the moving platform 1, the support roller 32 can move up and abut against the side of each plate, so that the bottom of the stacked plates can be supported, and the rolling support roller 32 makes it easy for the moving arm 11 to move away from the stacked plates.

[0029] Reference Figure 1 and Figure 3 To prevent the lifting arm 11 from directly colliding with the stacked plates, the handling device based on the overhead rail vehicle of this application also includes a buffer assembly 5. The buffer assembly 5 is symmetrically arranged in four sets and is respectively connected to two sets of lifting arms 11. The buffer assembly 5 includes a buffer bracket 51, a buffer rod 52, a buffer plate 53, a limiting block 54, and a buffer elastic element 55.

[0030] Reference Figure 3The buffer bracket 51 is fixed on the moving arm 11, the buffer rod 52 slides through the buffer bracket 51, the buffer plate 53 is fixed on the buffer rod 52, the limiting block 54 is set on the buffer rod 52 and moves within the buffer bracket 51, the buffer bracket 51 is used to limit the movement stroke of the limiting block 54, the buffer elastic element 55 is set between the buffer bracket 51 and the buffer plate 53, the buffer elastic element 55 is sleeved on the buffer rod 52, the buffer elastic element 55 is used to drive the buffer plate 53 away from the buffer bracket 51.

[0031] In this embodiment, each set of buffer components 5 has two buffer brackets 51, which are located on the opposite sides of the two moving arms 11. There are two buffer rods 52, two limiting blocks 54 and two buffer elastic elements 55, which correspond one-to-one with the buffer brackets 51. The buffer elastic element 55 is a spring.

[0032] When the lifting arm 11 approaches the stacked plates, the buffer plate 53 can first come into contact with the stacked plates. As the lifting arm 11 continues to approach the stacked plates, the buffer plate 53 can compress the buffer elastic element 55, so that the buffer plate 53 can elastically press against the stacked plates, buffering the collision between the lifting arm 11 and the stacked plates, thereby making the stacked plates less prone to damage.

[0033] After the lifting arm 11 moves into place, the buffer plate 53 can continuously apply force to the stacked plates under the elastic force of the buffer elastic element 55, so that the stacked plates can also be subjected to elastic clamping force, thereby making the handling of the stacked plates more stable.

[0034] When the limiting block 54 moves to the position closest to the safety elastic member 43, it can prevent the buffer rod 52 from sliding out of the buffer bracket 51. When the limiting block 54 moves to the position furthest from the safety elastic member 43, it can prevent the buffer plate 53 from further squeezing the buffer elastic member 55, so that the buffer assembly 5 can operate safely.

[0035] Furthermore, referring to Figure 3 In order to facilitate the adjustment of the elastic buffering force of the buffer plate 53 on the stacked plates, the limiting block 54 is in the shape of a ring and is sleeved on the buffer rod 52. The limiting block 54 has a fastening notch 541 for adjusting the degree of compression between the limiting block 54 and the buffer rod 52. The fastening notch 541 connects the inside and outside of the limiting block 54. A fixing bolt 56 is threaded through the limiting block 54. The fixing bolt 56 is used to tighten the limiting block 54 on the buffer rod 52.

[0036] After the fixing bolt 56 is loosened, the limiting block 54 can slide relative to the buffer rod 52, so that the position of the limiting block 54 can be adjusted, thereby adjusting the initial elastic force value of the buffer elastic element 55, and adjusting the buffering force of the buffer plate 53 on the stacked plates.

[0037] Reference Figure 1 To prevent the stacked panels from being misaligned, the present application provides a handling device based on a railcar, which also includes a detection component 6. Two sets of detection components 6 are symmetrically arranged and are respectively connected to two sets of protective arms 12. The drive component 2 is used to drive the two sets of protective arms 12 to slide synchronously by the same distance. The detection component 6 is used to abut against the surface of the panel to detect the overall centering of the stacked panels.

[0038] Since the two sets of protective arms 12 will slide synchronously by the same distance, the two sets of detection components 6 can also move towards each other by the same distance. When the two sets of detection components 6 synchronously contact the plate within the allowable range of detection error, it indicates that the stacked plate is in the center position. At this time, the stacked plate is not prone to deviation during handling. When one set of detection components 6 contacts the plate first, it indicates that the stacked plate is not in the center position. At this time, it is not advisable to handle the stacked plate.

[0039] Specifically, refer to Figure 4 The detection component 6 includes a mounting bracket 61 fixed to one of the protective arms 12.

[0040] A detection rod 62 is rotatably connected to the mounting frame 61. The detection rod 62 has a detection surface 621 bent near one end and a feedback surface 622 bent near the other end. The detection surface 621 is used to press against the outermost plate of the stacked plates. A displacement sensor 63 is fixed on the mounting frame 61. The displacement sensor 63 is used to output the displacement signal of the feedback surface 622 relative to itself. A detection elastic element 64 is hooked between the end of the detection rod 62 near the feedback surface 622 and the mounting frame 61. The detection elastic element 64 is used to drive the detection surface 621 of the detection rod 62 to swing to an inclined state.

[0041] In this embodiment, the detection surface 621 is perpendicular to the feedback surface 622; the detection elastic element 64 is a tension spring.

[0042] When the protective arm 12 approaches the surface of the plate, the detection surface 621 can first abut against the surface of the plate. As the protective arm 12 continues to approach the plate, the plate can push the detection rod 62 to swing. When the detection rod 62 swings, the distance between the feedback surface 622 and the displacement sensor 63 will change, causing the displacement signal output by the displacement sensor 63 to change. By monitoring the displacement signals of the two displacement sensors 63, it can be determined whether the two detection rods 62 swing synchronously within the detection error range, thus facilitating the detection of whether the stacked plates are in the center position.

[0043] Specifically, refer to Figure 2 The drive assembly 2 includes a moving drive unit 21 and a protective drive unit 22.

[0044] Reference Figure 5The moving drive unit 21 includes a moving motor 211, a moving drive pulley 212, a moving driven pulley 213, a moving belt 214, and a moving carriage 215.

[0045] The moving motor 211 is fixedly connected to one end of the moving platform 1 along its length. The moving drive pulley 212 is fixedly connected to the output shaft of the moving motor 211. The moving driven pulley 213 is rotatably connected to the other end of the moving platform 1 along its length. The moving belt 214 is wound around the moving drive pulley 212 and the moving driven pulley 213.

[0046] Reference Figure 2 and Figure 5 There are two moving slides 215, both of which are slidably connected to the moving platform 1. One moving slide 215 is fixedly connected to the side of the moving belt 214 near the moving platform 1 and is fixedly connected to two moving arms 11 of one group. The other moving slide 215 is fixedly connected to the side of the moving belt 214 away from the moving platform 1 and is fixedly connected to two moving arms 11 of another group.

[0047] The moving motor 211 can drive the moving belt 214 to rotate by moving the driving pulley 212. With the support of the driven pulley 213, the moving belt 214 can drive the two moving carriages 215 to move closer or further away from each other, so that the two sets of moving arms 11 can move closer or further away from each other.

[0048] Reference Figure 5 The protective drive unit 22 includes a protective motor 221, a protective drive pulley 222, a protective driven pulley 223, a protective auxiliary pulley 224, a protective belt 225, and a protective slide 226.

[0049] The protective motor 221 is fixedly connected to the middle of the moving platform 1. The protective drive pulley 222 is fixedly connected to the output shaft of the protective motor 221. There are two protective driven pulleys 223, which are rotatably connected to both ends of the moving platform 1 in the width direction. There are two protective auxiliary pulleys 224, which are symmetrically arranged on both sides of the protective drive pulley 222. The protective auxiliary pulleys 224 are rotatably connected to the moving platform 1. The protective belt 225 is wound around the protective drive pulley 222 and the two protective driven pulleys 223. The two protective auxiliary pulleys 224 are pressed against the outer side of the protective belt 225.

[0050] Reference Figure 2 and Figure 5There are two protective slides 226. Both protective slides 226 are slidably connected to the moving platform 1. One protective slide 226 is fixed to the side of the protective belt 225 near the moving platform 1 and is fixed to both of the two protective arms 12 in one group. The other protective slide 226 is fixed to the side of the protective belt 225 away from the moving platform 1 and is fixed to both of the two protective arms 12 in another group.

[0051] The protective motor 221 can drive the protective belt 225 to rotate through the protective drive pulley 222. With the support of the protective driven pulley 223, the protective belt 225 can drive the two protective slides 226 to move closer or further apart, thereby enabling the two sets of protective arms 12 to move closer or further apart.

[0052] The implementation principle of a handling device based on a cable car in this application embodiment is as follows: In use, the cable car drives the moving platform 1 to move to the stacked panels, and the supporting roller 32 is positioned below the stacked panels. The driving component 2 drives the moving arm 11 and the protective arm 12 to slide, so that the moving arm 11 and the protective arm 12 surround the stacked panels. The stacked panels push the detection rod 62 to swing. When the two detection rods 62 swing synchronously within the allowable range of detection error, the cable car lifts the moving platform 1, so that the supporting roller 32 supports the bottom of the stacked panels. The detection rod 62 elastically blocks the side of the stacked panels to stably handle the unpacked stacked panels. When one of the detection rods 62 swings first, it is necessary to stop the continued handling of the stacked panels. After manually adjusting the position of the stacked panels to be centered, the driving component 2 drives the moving arm 11 and the protective arm 12 to surround the stacked panels again to continue handling the stacked panels. Thus, this application enables the entire stack of panels to be stably handled without being packaged. Example 2:

[0053] Reference Figure 6 The difference between this embodiment and embodiment 1 is that the supporting component 3 further includes an extension roller 33 and an extension portion 34.

[0054] Reference Figure 7 The extension roller 33 is located on the side of the support roller 32 away from the support plate 31, and at least one is provided in the direction away from the support plate 31. All extension rollers 33 are connected to the support plate 31 through extensions 34. In this embodiment, the number of extension rollers 33 is three.

[0055] Under normal conditions, the extension roller 33 closest to the support roller 32 abuts against the support roller 32, and two adjacent support rollers 32 abut against each other.

[0056] Reference Figure 8When the stacked plates come into contact with the support roller 32, the extension 34 is used to increase the distance between the extension roller 33 closest to the support roller 32 and the support roller 32, and the extension 34 is used to increase the distance between two adjacent extension rollers 33.

[0057] When the stacked plates come into contact with the support roller 32, the extension 34 can increase the distance between the extension roller 33 closest to the support roller 32 and the support roller 32, and can also increase the distance between two adjacent extension rollers 33. Since the extension rollers 33 can be supported by the support plate 31 through the extension 34, the support area of ​​the stacked plates is increased by increasing the distance between the support roller 32 and the extension rollers 33 and between two adjacent extension rollers 33, thus making the support effect of the stacked plates better.

[0058] Specifically, refer to Figure 7 The extension 34 includes an extension slide bar 341, a connecting rod 342, and a hinge roller 343.

[0059] There are two extension slide rods 341, which are located at both ends of the support roller 32. The extension slide rods 341 are slidably connected to the support plate 31. The extension slide rods 341 are provided with support grooves 3411. The end of the extension roller 33 furthest from the support roller 32 is rotatably mounted on the extension slide rod 341 closest to it. The ends of the other extension rollers 33 are slidably and rotatably mounted in the support grooves 3411 closest to them.

[0060] In this embodiment, both ends of the support roller 32 have a rotating shaft 321 extending from them. The rotating shaft 321 is rotatably mounted on the support plate 31 and extends out of the support groove 3411. The rotating shaft 321 can rotate and slide relative to the extension slide rod 341. Both ends of the extension roller 33 have a support shaft 331 extending from them. The support shaft 331 of the extension roller 33 furthest from the support roller 32 is rotatably mounted on the extension slide rod 341 and extends out of the extension slide rod 341. The support shafts 331 of the remaining extension rollers 33 slide and rotate within the support groove 3411 closest to them. The support shafts 331 of the remaining extension rollers 33 extend out of the support groove 3411.

[0061] There are six sets of connecting rods 342, which are arranged one-to-one between the ends of the support roller 32 and the extension roller 33, and between the ends of two adjacent extension rollers 33. Each set of connecting rods 342 has two rods, one of which is rotatably connected to the end of the rotating shaft 321 or the support shaft 331, and the other is rotatably connected to the end of the support shaft 331. There are three hinge rollers 343, which are arranged one-to-one between two sets of connecting rods 342. The ends of the hinge rollers 343 are rotatably connected to the ends of the two connecting rods 342 that are close to each other. The hinge rollers 343 hinge the two connecting rods 342, and the hinge rollers 343 can rotate relative to the two connecting rods 342.

[0062] A retractable elastic element 344 is provided between the rotating shaft 321 and the support shaft 331, as well as between two adjacent support shafts 331. One end of the retractable elastic element 344 is rotatably connected to the rotating shaft 321 or the support shaft 331, and the other end is rotatably connected to the support shaft 331. The retractable elastic element 344 is used to drive the support roller 32 and the extension roller 33 or two adjacent extension rollers 33 to move closer to each other. In this embodiment, the retractable elastic element 344 is located in the support groove 3411, and the retractable elastic element 344 is a tension spring.

[0063] The weight of the stacked plates acts on the hinge roller 343, causing the hinge roller 343 to move downwards. The hinge roller 343 pushes the connecting rod 342 to swing, increasing the angle between the two connecting rods 342 in each group. This increases the distance between the support roller 32 and the extension roller 33, as well as between two adjacent extension rollers 33, and allows the retractable elastic element 344 to accumulate elastic force. Thus, the position of the extension roller 33 can be adjusted by the weight of the stacked plates. After the stacked plates are unloaded, under the elastic force of the retractable elastic element 344, the extension roller 33 can abut against the support roller 32, and two adjacent extension rollers 33 can abut against each other, so that the support roller 32 and the extension roller 33 can move under the stacked plates within the limited sliding stroke of the moving arm 11.

[0064] Reference Figure 7 In order to improve the safety of handling stacked panels, the present application provides a handling device based on a railcar, which also includes a safety component 4. The safety component 4 is disposed in one of the support slots 3411 and includes a pressure sensor 41, a compression block 42 and a safety elastic element 43.

[0065] The pressure sensor 41 is fixedly connected to the support plate 31, and the extrusion block 42 is slidably disposed in the support groove 3411. The extrusion block 42 is connected to the extension slide rod 341 through the safety elastic element 43.

[0066] Reference Figure 8 When the angle between the two connecting rods 342 in each group reaches its maximum, the pressing block 42 is pressed against the pressure sensor 41 by the elastic force of the safety elastic element 43.

[0067] Reference Figure 2 and Figure 8 The pressure sensor 41 is electrically connected to the controller, and the controller is electrically connected to the drive assembly 2. The pressure sensor 41 is used to output a pressure signal, and the controller responds to the pressure signal output by the pressure sensor 41 and is used to control the drive assembly 2 to be in a stopped state.

[0068] In this embodiment, the safety elastic element 43 is a spring. One end of the safety elastic element 43 is fixedly connected to the compression block 42, and the other end is fixedly connected to the extension slide bar 341. The controller can control the moving motor 211 and the protective motor 221 of the drive assembly 2 to be in a stopped state based on the pressure signal.

[0069] When the stacked panels are pressed onto the support rollers 32, hinge rollers 343, and extension rollers 33, the angle between the two connecting rods 342 in each group reaches its maximum. At this time, the pressing block 42 can press against the pressure sensor 41 under the elastic force of the safety elastic element 43, causing the pressure signal output by the pressure sensor 41 to change. Based on the pressure signal, the controller can control the moving motor 211 and the protective motor 221 to stop, making it difficult to change the position of the moving arm 11 and the protective arm 12. This makes it less likely for the stacked panels to fall off due to malfunction or misoperation during the handling process.

[0070] This application also discloses a transportation method based on a skyrail vehicle.

[0071] A method for transporting materials based on a skyrail vehicle, employing the aforementioned skyrail vehicle-based transport device, includes the following steps: Approach: The moving platform 1, driven by the overhead rail vehicle, is moved horizontally to above the clamping tray holding the stacked plates; Lowering: The overhead rail car vertically lowers the moving platform 1, placing the stacked plates within the area enclosed by the moving arm 11 and the protective arm 12, until the support roller 32, the extension roller 33, and the articulated roller 343 are all below the stacked plates. Encirclement: The moving motor 211 drives the moving arm 11 to slide towards the stacked plates, so that the moving arm 11 is close to the side of the plates; the protective motor 221 drives the protective arm 12 to slide towards the stacked plates, so that the protective arm 12 is close to the surface of the plates. Detection: The protective arm 12 moves the detection rod 62 close to the plate. The plate pushes the detection rod 62 to swing until the detection surface 621 of the detection rod 62 is in contact with the plate surface, so that the displacement signals of the two displacement sensors 63 change synchronously. If the displacement signal of one of the displacement sensors 63 changes first, the encirclement of the stacked plates by the moving arm 11 and the protective arm 12 is released first. The position of the stacked plates on the clamping tray is adjusted manually, and then the above encirclement steps are repeated. Support: The overhead rail car vertically lifts the moving platform 1, so that the articulated roller 343 can support the bottom of the stacked plates. Under the gravity of the stacked plates, the articulated roller 343 drives the connecting rod 342 to swing, which increases the distance between the support roller 32 and the extension roller 33 and between two adjacent extension rollers 33, so that the support roller 32, the articulated roller 343 and the extension roller 33 all abut against the bottom of the stacked plates. Locking: The pressing block 42 is pressed against the pressure sensor 41 under the action of the safety elastic element 43. Based on the pressure signal output by the pressure sensor 41, the controller controls both the moving motor 211 and the protective motor 221 to be in a stopped state. Handling: The overhead rail car continues to drive the moving platform 1 upward, so that the stacked plates are separated from the clamping pallet. The overhead rail car drives the moving platform 1 to move horizontally and move the stacked plates to the preset position. Release: After the stacked plates are placed on the clamping tray at the preset position, the support roller 32 and the extension roller 33 are disengaged from the bottom of the stacked plates under the action of the retracting elastic member 344. The moving motor 211 drives the moving arm 11 to slide away from the stacked plates, the hinge roller 343 rolls relative to the bottom of the stacked plates, and the protective motor 221 drives the protective arm 12 to slide away from the stacked plates, releasing the stacked plates and placing them on the clamping tray at the preset position.

[0072] With the above solution, even when the stacked panels are not packaged or bundled, the panels that are scattered and stacked vertically can be transported stably without the risk of tilting. During the transport process, the positions of the lifting arm 11 and the protective arm 12 can be locked to prevent the stacked panels from falling off, thus enabling the entire stack of panels to be transported stably without being packaged.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
