[0036] Example 1

[0037] Embodiments of the present invention provide a material conveying device, such as... Figures 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 shelf 4, and a stop component 5. The horizontal moving component 1 is connected to the vertical moving component 2. The shelf 4 is slidably 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 shelf 4 to switch from the vertical moving component 2 to the horizontal moving component 1. The stop component 5 is located at the vertical moving component 2 and has a first state of being fixedly connected to the shelf 4 to prevent the shelf 4 from rotating and a second state of being disengaged from the shelf 4.

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

[0039] In this embodiment, materials are placed on the shelf 4. The moving switching component 3 drives the shelf 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 disengaged from the shelf 4. When the shelf 4 needs to move horizontally to a specific position, the stop component 5 first activates, switching to the first state, that is, it is fixedly connected to the shelf 4 to prevent the shelf 4 from rotating. At this time, the moving switching component 3 drives the shelf 4 to the horizontal moving component 1. During the process of the moving switching component 3 switching from the vertical moving component 2 to the horizontal moving component 1, the moving switching component 3 switches by rotation. During rotation, since the stop component 5 is in the first state and fixed to the shelf 4, the shelf 4 will not rotate, and the materials on the shelf 4 will not tilt. In this way, the technical problem of material quality being affected by overturning or tilting during the material transportation process is avoided.

[0040] In a specific embodiment, such as Figure 1and Figure 3 As shown, the moving switching component 3 includes a sliding unit 31, a rotating unit 32, a horizontal power block 33, and a vertical power block 34. The shelf 4 is disposed 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 disposed on the horizontal moving component 1, and the vertical power block 34 is disposed on the vertical moving component 2. The shelf 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, when the stop component 5 is in the first state, the rotating unit 32 drives the sliding unit 31 to rotate, thereby causing it to move along the horizontal moving component 1 under the drive of the horizontal power block 33.

[0041] Specifically, the sliding unit 31 is mainly used to drive the shelf 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, causing it to move onto the horizontal moving component 1. Since the sliding unit 31 and the shelf 4 are fixedly connected, the shelf 4 will also rotate during the rotation of the sliding unit 31. To address this issue, this embodiment also includes a stop component 5. The stop component 5 passes through the sliding unit 31 and is fixed to the shelf 4. The stop component 5 is movably connected to the sliding unit 31. After passing through the sliding unit 31, the sliding unit 31 can still rotate, while the stop component 5 is fixedly connected to the shelf 4, which can fix the shelf 4 in the current position. The horizontal power block 33 is used to connect the horizontal belt power unit 11 and the sliding unit 31, and the vertical power block 34 is used to connect the vertical belt power unit 21 and the sliding unit 31.

[0042] In a specific embodiment, such as Figure 3 As shown, the sliding unit 31 includes a track-changing track 311, a motion back plate 312, and rollers 313. The vertical moving component 2 includes a vertical track with a space in the middle for setting the track-changing track 311. The rollers 313 are fixed on the inner side of the motion back plate 312. The rollers 313 match the track grooves on both sides of the track-changing track 311 and the vertical track. The horizontal power block 33 can drive the motion back plate 312 to move along the vertical track or the track-changing track 311 through the rollers 313.

[0043] In addition, the horizontal power block 33 is clamped on the horizontal belt power unit 11 and can move horizontally along with the horizontal belt power unit 11; the horizontal power block 33 has a first matching hole, and the motion backboard 312 has a pneumatic cylinder 314; when the rotating unit 32 drives the sliding unit 31 to rotate to a position, the pneumatic cylinder 314 matches with the first matching hole, and then the horizontal belt power unit 11 moves horizontally, and the motion backboard 312 moves horizontally through the horizontal power block 33 and the pneumatic cylinder 314. The vertical power block 34 is clamped on the vertical belt power unit 21 and can move horizontally along with the vertical belt power unit 21; the vertical power block 34 has a second matching hole, and the pneumatic cylinder 314 on the motion backboard 312 matches with the second matching hole, so that the vertical belt power unit 21 can drive the motion backboard 312 to move in the vertical direction through the vertical power block 34 and the pneumatic cylinder 314.

[0044] In the embodiment, the middle part of the vertical rail 22 has a space for arranging the rail changing rail 311, that is, the vertical rail 22 includes two parts, for better explanation, it is assumed that the vertical rail 22 includes a first vertical rail and a second vertical rail, which are arranged in correspondence with each other and have a space between them, and the rail changing rail 311 is arranged in the space, that is, along the vertical direction, from top to bottom, the first vertical rail, the rail changing rail 311 and the second vertical rail. During transportation, from bottom to top, the roller 313 can move along the second vertical rail, the rail changing rail 311 and the first vertical rail in turn, and the roller 313 is fixed on the motion backboard 312, so as to realize the up-down movement of the motion backboard 312. When it is necessary to change the moving direction of the shelf 4, the rotating unit 32 needs to work at a specific position, which refers to the position when the roller 313 moves to the rail changing rail 311. In the early stage of design, the space between the first vertical rail and the second vertical rail corresponds to the horizontal moving assembly 1, so that after the rotating unit 32 drives the sliding unit 31 to rotate, the sliding unit 31 can be connected with the horizontal moving assembly 1, thereby changing the moving direction of the shelf 4.

[0045] In specific embodiments, as Figure 1 and Figure 3As shown, the material conveying device further comprises an electromagnetic brake 6, the outer side of the moving back plate 312 is connected with the shelf 4 through the electromagnetic brake 6. The electromagnetic brake 6 is a connector that transmits the driving side torsion to the passive side, which can be freely combined, cut off or braked as needed. In this embodiment, the driving side of the electromagnetic brake 6 is connected with the shelf 4, and the passive side is connected with the moving back plate 312. During the up and down movement of the shelf, the driving side and the passive side are adsorbed with each other, realizing the fixation of the shelf and the moving back plate 312, and avoiding the shaking of the shelf 4 during the movement. When the sliding unit 31 needs to be rotated, the adsorption force between the driving side and the passive side is released, and when the rotation of the sliding unit 31 is completed, the adsorption can be performed again.

[0046] In specific embodiments, as shown in Figure 7 、 Figure 8 and Figure 9 , the roller 313 is provided with a plurality of rollers 313, which are uniformly distributed on both sides of the rail changing track 311; the moving switching assembly 3 further comprises a limiting unit 35, the limiting unit 35 comprises a limiting motor 351, the output end of the limiting motor 351 is connected with a connecting rod 352, and the connecting rod 352 is connected with the rollers 313 on both sides through a connecting joint 353; the limiting motor 351 works, which drives the connecting joint 353 to stretch in or out through the connecting rod 352, so as to make the roller 313 tightly or loosen with the rail changing track 311.

[0047] In order to better explain and illustrate, it is assumed that in some embodiments, the roller 313 is provided with four rollers, which are respectively 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 segment of the rail changing track 311, and the third roller and the fourth roller are located on both sides of the lower segment of the rail changing track 311. The limiting unit 35 comprises two, which are respectively 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 moving direction, the horizontal belt power unit 11 is disconnected with the moving backboard 312. In order to prevent the moving backboard 312 and the roller 313 from falling off or deviating without power limitation, the position of the roller 313 relative to the track switching track 311 needs to be limited to ensure that the roller 313 and the track switching track 311 do not move relative to each other. Specifically, when the first roller and the second roller need to be limited, the output shaft of the limiting motor 351 of the upper limiting unit rotates, 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, and then the first roller and the second roller are tightly held with the track switching track 311, limiting the movement of the first roller and the second roller relative to the track switching track 311. When the third roller and the fourth roller need to be limited, the output shaft of the limiting motor 351 of the lower limiting unit rotates, drives the connecting joint 353 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 held with the track switching track 311, limiting the movement of the third roller and the fourth roller relative to the track switching track 311. The way to release the roller 313 is opposite to the above-mentioned way of holding, only the reverse rotation of the output shaft of the limiting motor 351 is needed.

[0049] In specific embodiments, as shown in Figure 3 The rotating unit 32 includes a rotating motor 321, a speed reducer 322, a gear 323, and a rotating backboard 324, which are connected in sequence. The rotating backboard 324 is connected with the track switching track 311. The rotating motor 321 can drive the sliding unit 31 to rotate at a specific position through the speed reducer 322, the gear 323, and the rotating backboard 324. The output shaft of the rotating motor 321 is connected with the gear 323 through the speed reducer 322. The back of the rotating backboard 324 has a ring of toothed structure which is engaged with the gear 323. In this way, when the rotating motor 321 works, it can drive the gear 323 to rotate through the speed reducer 322, and then drive the rotating backboard 324 to rotate through the cooperation of the gear 323 and the toothed structure, and then drive the track switching track 311 to rotate.

[0050] In specific embodiments, as shown in Figure 4 , Figure 5 and Figure 6As shown, the stop component 5 comprises a driving unit 51, a rotation-stopping shaft body 52, a bearing 53 and a motion rotation-stopping shaft 56. The motion back plate 312 is provided with a hole, the bearing 53 is located in the hole, the rotation-stopping shaft body 52 penetrates through the bearing 53, and the driving unit 51 can drive the rotation-stopping shaft body 52 to move so as to be connected with the motion rotation-stopping shaft 56 in the shelf 4 to fix the shelf 4. When it is needed to change the running direction of the sliding unit 31, the driving unit 51 drives the rotation-stopping shaft body 52 to be fixedly connected with the spline of the motion rotation-stopping shaft 56 in the shelf 4, so that the shelf 4 is fixed, and tilting of the shelf 4 when the running direction is changed is avoided. In this process, the bearing 53 is arranged in the hole of the motion back plate 312, and the rotation-stopping shaft body 52 penetrates through the bearing 53, so that the rotation of the motion back plate 312 is not affected.

[0051] In specific embodiments, the driving unit 51 comprises a coil 511, and the coil 511 is provided with a permanent magnet block 512. The coil 511 and the permanent magnet block 512 are matched to push the rotation-stopping shaft body 52 to move to the spline in the shelf 4. The rotation-stopping shaft body 52 can be pushed out to the spline of the motion rotation-stopping shaft 56 in the shelf 4 under the cooperation of the coil 511 and the permanent magnet block 512, so as to fix the shelf 4.

[0052] In specific embodiments, the stop component 5 further comprises a flange 54, the flange 54 is provided with a shaft sleeve 55, and the end of the rotation-stopping shaft body 52 penetrates through the shaft sleeve 55. The driving unit 51 further comprises a spring 513, the spring 513 is located in the flange 54 and abuts on the coil 511, so that when the rotation of the sliding unit 31 is completed and the electromagnetic brake 6 is adsorbed and braked, the rotation-stopping shaft body 52 can be reset under the action of the spring 513.

[0053] The material conveying device provided in the embodiment can prevent the moving back plate 312 and the roller 313 from falling off or deviating without power limitation when moving to a specific position where the track needs to be changed. Then, the rotation stopping shaft body 52 is extended to the spline of the moving rotation stopping shaft 56 under the pushing of the electromagnetic coil, so as to fix the rotation stopping shaft body 52. The moving rotation stopping shaft 56 is connected with the storage rack 4, so as to prevent the rotation of the storage rack 4. 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, the rotating motor 321 drives the gear 323 to drive the rotating back plate 324 to rotate through the speed reducer 322, the rotating back plate 324 rotates while driving the track changing track 311 and the moving back plate 312 to rotate at the same time, the storage rack 4 remains not to rotate under the positioning of the rotation stopping shaft body 52, and the electromagnetic brake 6 is attracted and braked after the rotation is completed. The rotation stopping shaft body 52 is retracted under the action of the spring 513, the limiting motor 351 drives the connecting rod 352 and the connecting joint 353 to loosen the roller 313, and the air cylinder 314 is switched to the horizontal power block 33 on the horizontal belt power unit 11.
