[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Example 1

[0037] An embodiment of the present invention provides a material conveying device, such as Figure 1-9 As shown, the material conveying device includes a horizontal moving component 1, a vertical moving component 2, a moving switching component 3, a rack 4 and a stopping component 5. The horizontal moving component 1 is connected to the vertical moving component 2, and the rack 4 is slidingly connected to the vertical moving component 2 or the horizontal moving component 1 through the moving switching component 3. The moving switching component 3 can drive the rack 4 to switch from the vertical moving component 2 to the horizontal moving component 1. The stopping component 5 is arranged at the vertical moving component 2, and it has a first state fixedly connected to the rack 4 to prevent the rack 4 from rotating and a second state detached from the rack 4.

[0038] Specifically, the horizontal moving assembly 1 includes a horizontal belt power unit 11, a horizontal track 12, a horizontal guide rail 13 and a horizontal guide rail fixing plate 14, wherein the horizontal track 12 and the horizontal guide rail 13 are both fixed on the horizontal guide rail fixing plate 14, and the horizontal belt power unit 11 is located above the horizontal guide rail fixing plate 14, and the rotation of the horizontal belt power unit 11 can drive the storage rack 4 to move horizontally. The vertical moving assembly 2 includes a vertical belt power unit 21, a vertical track 22, a vertical guide rail 23 and a vertical guide rail fixing plate 24, wherein the vertical track 22 and the vertical guide rail 23 are both fixed on the vertical guide rail fixing plate 24, and the vertical belt power unit 21 is located above the vertical guide rail fixing plate 24, and the rotation of the vertical belt power unit 21 can drive the storage rack 4 to move vertically.

[0039] In this embodiment, the material is placed on the rack 4, and the mobile switching component 3 drives the rack 4 to move up and down along the vertical moving component 2. During this process, the stop component 5 is in the second state, that is, the stop component 5 is separated from the rack 4; when the rack 4 moves to a specific position and needs to move horizontally, the stop component 5 is first actuated and converted to the first state, that is, fixedly connected to the rack 4 to prevent the rack 4 from rotating. At this time, the mobile switching component 3 drives the rack 4 to move to the horizontal moving component 1. In the process of the mobile switching component 3 being converted from the vertical moving component 2 to the horizontal moving component 1, the mobile switching component 3 is converted by rotating. During the rotation, since the stop component 5 is in the first state, it is fixed to the rack 4, so the rack 4 will not rotate, and the material on the rack 4 will not tilt. In this way, the technical problem of flipping, tilting, etc. in the material transportation process affecting the material quality is avoided.

[0040] In a specific embodiment, Figure 1and Figure 3 As shown, the mobile switching component 3 includes a sliding unit 31, a rotating unit 32, a horizontal power block 33 and a vertical power block 34. The storage rack 4 is arranged on one side of the sliding unit 31, and the other side of the sliding unit 31 is connected to the rotating unit 32. The horizontal power block 33 is arranged on the horizontal moving component 1, and the vertical power block 34 is arranged on the vertical moving component 2. The storage rack 4 moves along the vertical moving component 2 through the sliding unit 31 and driven by the vertical power block 34. At a specific position, the rotating unit 32 drives the sliding unit 31 to rotate when the stop component 5 is in the first state, so that it moves along the horizontal moving component 1 driven by the horizontal power block 33.

[0041] Specifically, the sliding unit 31 is mainly used to drive the rack 4 to move up and down along the horizontal moving component 1 or along the vertical moving component 2. Therefore, the direction of the sliding unit 31 can be switched, and the rotating unit 32 is used to change the direction of the sliding unit 31. When the sliding unit 31 moves to a specific position, the rotating unit 32 drives the sliding unit 31 to rotate so that it moves to the horizontal moving component 1. Since the sliding unit 31 is fixedly connected to the rack 4, the rack 4 will also rotate during the rotation of the sliding unit 31. In response to this problem, the present embodiment also includes a stopper assembly 5, which passes through the sliding unit 31 and is fixed to the rack 4. The stopper assembly 5 is movably connected to the sliding unit 31. After passing through the sliding unit 31, the sliding unit 31 can still rotate, and the stopper assembly 5 is fixedly connected to the rack 4, which can fix the rack 4 at the current position. The horizontal power block 33 is used to realize the connection between the horizontal belt power unit 11 and the sliding unit 31 , and the vertical power block 34 is used to realize the connection between the vertical belt power unit 21 and the sliding unit 31 .

[0042] In a specific embodiment, Figure 3 As shown, the sliding unit 31 includes a track-changing track 311, a moving back plate 312 and a roller 313; the vertical moving component 2 includes a vertical track; the middle portion of the vertical track has a space for setting the track-changing track 311; the roller 313 is fixed to the inner side of the moving back plate 312; the roller 313 matches the track grooves on both sides of the track-changing track 311 and the vertical track; the horizontal power block 33 can drive the moving back plate 312 to move along the vertical track or the track-changing track 311 through the roller 313.

[0043] In addition, the horizontal power block 33 is clamped on the horizontal belt power unit 11, and it can move horizontally with the horizontal belt power unit 11; the horizontal power block 33 has a first matching hole, and the moving back plate 312 has a cylinder 314. When the rotating unit 32 drives the sliding unit 31 to rotate to the right position, the cylinder 314 matches with the first matching hole, and then the horizontal belt power unit 11 moves horizontally, and the moving back plate 312 is driven to move horizontally by the horizontal power block 33 and the cylinder 314. The vertical power block 34 is clamped on the vertical belt power unit 21, and it can move horizontally with the vertical belt power unit 21; the vertical power block 34 has a second matching hole, and after the cylinder 314 on the moving back plate 312 matches with the second matching hole, the vertical belt power unit 21 can drive the moving back plate 312 to move in the vertical direction through the vertical power block 34 and the cylinder 314.

[0044] In this embodiment, the middle part of the vertical track 22 has a space for setting the track-changing track 311, that is, the vertical track 22 includes two parts. For better explanation, it is assumed that the vertical track 22 includes a first vertical track and a second vertical track, and the first vertical track and the second vertical track are correspondingly arranged up and down and there is a space between the two. The track-changing track 311 is arranged in the space, that is, along the vertical direction, from top to bottom, there are the first vertical track, the track-changing track 311 and the second vertical track. During transportation, from bottom to top, the roller 313 can move along the second vertical track, the track-changing track 311 and the first vertical track in turn, and the roller 313 is fixed on the moving back plate 312, thereby realizing the up and down movement of the moving back plate 312. When the moving direction of the storage rack 4 needs to be changed, the rotating unit 32 needs to work at a specific position. The specific position refers to when the roller 313 moves to the track change track 311. In the initial design, the space between the first vertical track and the second vertical track corresponds to the horizontal moving component 1. Therefore, after the rotating unit 32 at the specific position drives the sliding unit 31 to rotate, the sliding unit 31 can dock with the horizontal moving component 1, thereby changing the moving direction of the storage rack 4.

[0045] In a specific embodiment, Figure 1 and Figure 3As shown, the material conveying device also includes an electromagnetic brake 6, and the outer side of the moving back plate 312 is connected to the storage rack 4 through the electromagnetic brake 6. The electromagnetic brake 6 is a connector that transmits the torque of the active side to the passive side, and can be freely combined, disconnected or braked as needed. In this embodiment, the active side of the electromagnetic brake 6 is connected to the storage rack 4, and the passive side is connected to the moving back plate 312. In the process of the storage rack moving up and down, the active side and the passive side are adsorbed to each other, so that the storage rack and the moving back plate 312 are fixed, and the storage rack 4 is prevented from shaking during the movement. When it is necessary to rotate the sliding unit 31, the adsorption force between the active side and the passive side is released, and when the rotation of the sliding unit 31 is completed, it can be adsorbed again.

[0046] In a specific embodiment, Figure 7 , Figure 8 as well as Fig. 9 As shown, a plurality of rollers 313 are provided, and the plurality of rollers 313 are evenly distributed on both sides of the track-changing track 311; the mobile switching component 3 also includes a limit unit 35, and the limit unit 35 includes a limit motor 351, and the output end of the limit motor 351 is connected to a connecting rod 352, and the connecting rod 352 is connected to the rollers 313 on both sides through a connecting joint 353; when the limit motor 351 works, it drives the connecting joint 353 to extend inward or outward through the connecting rod 352, thereby making the roller 313 and the track-changing track 311 clamped or loosened.

[0047] For better explanation, it is assumed that in a certain embodiment, four rollers 313 are provided, namely, a first roller, a second roller, a third roller and a fourth roller, wherein the first roller and the second roller are located on both sides of the upper section of the track-changing track 311, and the third roller and the fourth roller are located on both sides of the lower section of the track-changing track 311. The limiting units 35 include two, namely, an upper limiting unit for limiting the first roller and the second roller and a lower limiting unit for limiting the third roller and the fourth roller.

[0048] In the process of changing the direction of movement, the horizontal belt power unit 11 will be disconnected from the moving back plate 312. In order to prevent the moving back plate 312 and the roller 313 from falling off or shifting without power restriction, it is necessary to restrict the position of the roller 313 relative to the track-changing track 311 to ensure that the roller 313 and the track-changing track 311 do not move relative to each other. Specifically, when it is necessary to restrict the first roller and the second roller, the output shaft of the limit motor 351 of the upper limit unit rotates, and drives the connecting joint 353 to move upward through the connecting rod 352, so that the two sides of the connecting joint 353 are retracted inward, thereby making the first roller and the second roller hold the track-changing track 311 tightly, limiting the movement of the first roller and the second roller relative to the track-changing track 311. When the third roller and the fourth roller need to be limited, the output shaft of the limit motor 351 of the lower limit unit rotates, and the connecting joint 353 is driven to move downward through the connecting rod 352, so that the two sides of the connecting joint 353 are retracted inward, and then the third roller and the fourth roller are tightly clamped to the track-changing track 311, thereby limiting the movement of the third roller and the fourth roller relative to the track-changing track 311. The method of loosening the roller 313 is opposite to the above-mentioned clamping method, and only the output shaft of the limit motor 351 needs to be rotated in the opposite direction.

[0049] In a specific embodiment, Figure 3 As shown, the rotating unit 32 includes a rotating motor 321, a reducer 322, a gear 323 and a rotating back plate 324, wherein the rotating motor 321, the reducer 322, the gear 323 and the rotating back plate 324 are connected in sequence, and the rotating back plate 324 is connected to the track-changing track 311; when the rotating motor 321 is working, it can drive the sliding unit 31 to rotate at a specific position through the reducer 322, the gear 323 and the rotating back plate 324. The output shaft of the rotating motor 321 is connected to the gear 323 through the reducer 322, and the back of the rotating back plate 324 has a circle of toothed structure, which meshes with the gear 323. In this way, when the rotating motor 321 is working, it can drive the gear 323 to rotate through the reducer 322, and then drive the rotating back plate 324 to rotate through the cooperation of the gear 323 and the toothed structure, and then drive the track-changing track 311 to rotate.

[0050] In a specific embodiment, Figure 4 , Figure 5 as well as Figure 6As shown, the stop assembly 5 includes a driving unit 51, a stop shaft body 52, a bearing 53 and a moving stop shaft 56. A hole is provided on the moving back plate 312, and the bearing 53 is located in the hole. The stop shaft body 52 passes through the bearing 53. The driving unit 51 can drive the stop shaft body 52 to move so that it is connected with the moving stop shaft 56 in the rack 4 to fix the rack 4. When the running direction of the sliding unit 31 needs to be changed, the driving unit 51 drives the stop shaft body 52 to be fixedly connected with the spline of the moving stop shaft 56 in the rack 4, so that the rack 4 is fixed and tilting is avoided when the moving direction is changed. In this process, the hole of the moving back plate 312 has a bearing 53, and the stop shaft body 52 passes through the bearing 53, which will not affect the rotation of the moving back plate 312.

[0051] In a specific embodiment, the driving unit 51 includes a coil 511, and a permanent magnet block 512 is provided inside the coil 511. The coil 511 and the permanent magnet block 512 cooperate to push the anti-rotation shaft body 52 to move to the spline in the rack 4. The anti-rotation shaft body 52 can be pushed out to the spline of the moving anti-rotation shaft 56 in the rack 4 under the cooperation of the coil 511 and the permanent magnet block 512, thereby fixing the rack 4.

[0052] In a specific embodiment, the stop assembly 5 also includes a flange 54, a sleeve 55 is provided in the flange 54, and the end of the stop shaft 52 passes through the sleeve 55; the driving unit 51 also includes a spring 513, and the spring 513 is located in the flange 54 and abuts against the coil 511. When the sliding unit 31 completes the rotation and the electromagnetic brake 6 is adsorbed and braked, the stop shaft 52 can return to its original position under the action of the spring 513.

[0053] In the specific use process of the material conveying device provided in this embodiment, when it moves to a specific position where the track needs to be changed, the limit motor 351 drives the connecting joint 353 through the connecting rod 352, so that the roller 313 can hold the track change track 311 tightly, so as to prevent the moving back plate 312 and the roller 313 from falling off or deviating without power restriction. Then, the anti-rotation shaft body 52 is extended to the spline of the moving anti-rotation shaft 56 under the push of the electromagnetic coil, and the anti-rotation shaft body 52 is fixed, and the moving anti-rotation shaft 56 is connected to the storage rack 4, so as to prevent the storage rack 4 from rotating. After the storage rack 4 is fixed, the electromagnetic brake 6 is opened, the horizontal power block 33 and the vertical power block 34 are opened, and the rotating motor 321 drives the gear 323 through the reducer 322 to drive the rotating back plate 324 to rotate. The rotation of the rotating back plate 324 drives the track changing track 311 and the moving back plate 312 to rotate at the same time. The storage rack 4 remains fixed under the positioning of the stop shaft 52. After the rotation is completed, the electromagnetic brake 6 is adsorbed and braked, and the stop shaft 52 retreats under the action of the spring 513. The limit motor 351 drives the connecting rod 352 and the connecting joint 353 to release the roller 313, and the cylinder 314 switches to the horizontal power block 33 on the horizontal belt power unit 11. After completing the track changing action, horizontal transportation begins.
