Description

Technical Field

[0001] This technical solution relates to the field of material feeding equipment technology, specifically a multi-layer silo. Background Technology

[0002] Multi-layer silos are industrial equipment used for storing and conveying bulk materials. Their most prominent feature is the structure of multiple silo units connected vertically from top to bottom and from large to small. Multi-layer silos are often used in conjunction with feeding equipment. During the feeding process, one layer of silo unit needs to be pulled to a designated position, and then a robotic arm grabs the material placed in the silo unit to achieve feeding.

[0003] Chinese patent CN213568314U discloses a double-row, multi-layer, dot matrix hopper feeding device used in conjunction with a gantry robotic arm. The product placement station of this hopper device is achieved through support blocks. During the feeding process, the placement tray needs to be pulled onto the support blocks. During the pulling process, the friction between the support blocks and the placement tray will make the stability of the placement tray poor when moving, resulting in a jerking sensation. This will cause the material displacement to change position, making subsequent transfer inconvenient. At the same time, after long-term operation, the bottom of the hopper and the support blocks will be worn, which will cause the hopper to tilt and move, eventually causing the material to slide on the hopper.

[0004] In addition, Chinese patent CN223149528U discloses a multi-bin vertical lifting feeding device for automatically feeding materials to a robotic arm. After the bin plates stored in this device are placed in a designated position, they need to be grasped by a three-axis robotic arm. It cannot be adapted to a two-axis robotic arm, which results in low product adaptability and a complicated material handling process. Summary of the Invention

[0005] The purpose of this technical solution is to provide a multi-layer silo that, by setting up a material preparation mechanism, enables stable material conveying and solves the problem of poor stability of the original equipment during the material handling process.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A multi-layer silo includes: a frame having a material preparation area and a material feeding area; a material preparation mechanism disposed in the material preparation area for placing the silo; and a material feeding mechanism disposed in the material feeding area for pulling the silo; wherein, the material preparation mechanism includes a plurality of material preparation components, the material preparation components dividing the material preparation area into a plurality of layers; each material preparation component includes a material preparation wheel and a material preparation belt sleeved on the material preparation wheel; the material preparation belt receives the silo; the material preparation components are disposed on the left and right side walls of the frame, and at least one set of material preparation components is disposed on each side wall.

[0008] Preferably, the feeding mechanism includes a feeding frame and a material picking component, the material picking component being used to pull the hopper into the feeding frame; a material guiding component is provided on the inner wall of the feeding frame, the material guiding component including a material guiding wheel and a material guiding belt sleeved on the material guiding wheel; the material guiding belt receiving the hopper.

[0009] Preferably, the loading rack is movably mounted in the loading area via a lifting assembly, the lifting assembly comprising: a lifting drive component mounted on the loading rack, the output end of the lifting drive component being provided with a lifting gear; and a lifting rack mounted on the inner wall of the frame, the lifting gear meshing with the lifting rack.

[0010] Preferably, an auxiliary slider is provided on the outer wall of the feeding rack, and the auxiliary slider is movably mounted on an auxiliary guide rail provided on the inner wall of the frame.

[0011] Preferably, the material handling assembly includes: a material handling drive unit disposed below the loading rack, wherein both the output end of the material handling drive unit and the loading rack are provided with material handling wheels; a material handling belt sleeved on the two material handling wheels; and a material handling part disposed on the material handling belt for engaging with a recess on the hopper.

[0012] Preferably, the material handling assembly further includes: a material handling guide rail disposed on the loading rack; and a material handling slider movably disposed on the material handling guide rail and connected to the material handling part.

[0013] Preferably, the feeding rack is equipped with a baffle; when the hopper comes into contact with the baffle, the hopper is fully inserted into the feeding area.

[0014] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0015] 1. The feeding mechanism designed in this technical solution can pull the hopper to the feeding area. During this process, the material preparation belt moves with the hopper due to friction and drives the material preparation wheel to rotate. When the material preparation wheel rotates, the material preparation belt and the hopper become static friction. Therefore, the stability of the hopper after being pulled on the material preparation belt is much higher than that after being pulled directly on the support block. This greatly avoids the jerking sensation when pulling the hopper and also prevents the bottom surface of the hopper from being worn, thereby increasing the service life of the material preparation belt and the hopper.

[0016] 2. The multi-layer silo designed in this technical solution can be used with a two-axis robot. The material handling component will pull the silo to move gradually. During the movement of the silo, the material can be picked up by the two-axis robot. Here, "two axes" means that the robot does not need to move along the material handling direction. It only needs to complete the movement and vertical lifting in the plane perpendicular to the material handling direction. This improves the adaptability of the multi-layer silo.

[0024] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, a multi-layer silo includes a frame 1, a material preparation mechanism, and a feeding mechanism. The frame 1 is hollow inside, forming a material preparation area 11 at the front and a feeding area 12 at the rear. The material preparation mechanism includes several material preparation components 2, which divide the material preparation area 11 into several layers. Each layer of material preparation components 2 is used to carry the silo 7. When feeding is required, the feeding mechanism pulls the silo 7 into the feeding area 12, and then cooperates with the robot arm to realize feeding.

[0026] like Figure 2 As shown, the material preparation assembly 2 includes a material preparation wheel 21 and a material preparation belt 22. The material preparation belt 22 is sleeved on the outside of the material preparation wheel 21. The material preparation wheel 21 is rotatably disposed on the inner side wall of the material preparation area 11. Two material preparation wheels 21 and one material preparation belt 22 constitute a set of material preparation components. Each material preparation assembly 2 includes at least two sets of material preparation components disposed opposite to each other on the inner side wall of the material preparation area 11. Multiple sets of material preparation components can be disposed on the same side wall to increase the stability of the hopper 7 when it moves.

[0027] Furthermore, when the hopper 7 is pulled, friction is generated between the hopper 7 and the material preparation belt 22. This friction causes the material preparation belt 22 to move, which in turn drives the material preparation wheel 21 to rotate. After the material preparation wheel 21 rotates, there is no relative movement between the hopper 7 and the material preparation belt 22. By utilizing the static friction between the two, the jerking sensation when the hopper 7 moves can be reduced, thereby increasing the stability of the movement of the hopper 7. Therefore, it can be ensured that the position of the material placed on the hopper 7 does not change.

[0028] like Figure 3 and Figure 4 As shown, the feeding mechanism includes a feeding frame 3, a picking component 4, and a lifting component. The picking component 4 is used to pull the hopper 7 into the feeding frame 3. The lifting component is used to drive the feeding frame 3 to rise and fall, so that it can correspond to the hopper 7 at different positions in the material preparation area 11. When the lifting component drives the feeding frame 3 to the corresponding position, the picking component 4 pulls the hopper 7 into the feeding frame 3. At this time, the lifting component can drive the feeding frame 3 to rise to the highest position for the robot to pick up the material, or control the robot to descend to the designated position to pick up the material.

[0029] Furthermore, during the material handling process of the material handling component 4, the material guiding component 5 is needed to maintain the stability of the movement of the hopper 7, such as... Figure 4 and Figure 5 As shown, the material guiding assembly 5 includes a material guiding wheel 51 and a material guiding belt 52. The material guiding belt 52 is sleeved on the outside of the material guiding wheel 51. Two material guiding wheels 51 and one material guiding belt 52 constitute a set of material guiding components. The loading rack 3 is provided with at least two sets of material guiding components. These two sets of material guiding components are arranged opposite to each other on the two side walls of the loading rack 3. Multiple sets of material guiding components can also be provided on any side wall to increase the stability when receiving the material bin 7.

[0030] Furthermore, by adjusting the height of the feeding rack 3, the guide belt 52 can be aligned directly with the preparation belt 22. This prevents the hopper 7 from bumping as it moves from the preparation belt 22 onto the guide belt 52. Additionally, since the guide belt 52 is parallel to the feeding direction of the hopper 7, the movement of the hopper 7 on the guide belt 52 is also relatively smooth.

[0031] Furthermore, when multiple sets of guide components are installed on the side wall of the feeding rack 3, the distance between the two guide wheels 51 (i.e. the length of the guide belt 52) ​​can be adjusted to ensure that the hopper 7 does not tilt due to gravity after the front end of the hopper 7 leaves the first set of guide belts 52 and before it enters the second set of guide belts 52. The adjustment method is to make the length of the guide belt 52 greater than half the length of the hopper 7.

[0032] like Figure 3 and Figure 5As shown, the loading rack 3 is movably set in the loading area 12 via a lifting assembly. The lifting assembly includes a lifting drive 61, a lifting gear 62, and a lifting rack 63. The lifting drive 61 is set on the side wall of the loading rack 3 and located below the loading rack 3. The lifting gear 62 is set at the output end of the lifting drive 61, and the lifting rack 63 is set on the inner wall of the loading area 12. The lifting gear 62 meshes with the lifting rack 63, so that the lifting drive 61 can drive the lifting gear 62 to rotate, and then cooperate with the lifting rack 63 to realize the lifting and lowering of the loading rack 3.

[0033] Furthermore, at the other end of the feeding rack 3 ( Figure 3 The same lifting gear 62 and lifting rack 63 are respectively provided on the other inner wall of the feeding area 12 (the side not shown in the picture) and the other inner wall of the feeding area 12. In this way, the two sets of components work together to improve the stability of the feeding rack 3 when it is lifted.

[0034] Furthermore, such as Figure 3 and Figure 5 As shown, an auxiliary slider 31 is provided on the outer side wall of the loading rack 3. The auxiliary slider 31 is movably mounted on the auxiliary guide rail 32 provided on the inner wall of the frame 1. Similarly, the same auxiliary slider 31 and auxiliary guide rail 32 are provided on the other side wall of the loading rack 3 and the other inner wall of the frame 1, respectively. The design of the auxiliary slider 31 and auxiliary guide rail 32 is also used to improve the stability of the loading rack 3 when it is raised and lowered.

[0035] like Figure 6 As shown, the material handling assembly 4 includes a material handling drive 41, two material handling wheels 42, a material handling belt 43, and a material handling part 44. The material handling drive 41 is located below the loading frame 3. One of the material handling wheels 42 is located at the output end of the material handling drive 41, and the other is located on the loading frame 3 and on the opposite side of the material handling drive 41. The material handling belt 43 is sleeved on the two material handling wheels 42, and the material handling part 44 is located on the material handling belt 43. When the material handling drive 41 drives the material handling wheels 42 to rotate, the material handling belt 43 can drive the material handling part 44 to move. The material handling part 44 is a spherical protrusion. The material handling part 44 can extend into the bottom of the hopper 7 and cooperate with the recess on the hopper 7, thus pulling and moving the hopper 7.

[0036] Furthermore, the material handling assembly 4 also includes a material handling guide rail 45 and a material handling slider 46. The material handling guide rail 45 is mounted on the feeding rack 3, and the material handling slider 46 is movably mounted on the material handling guide rail 45 and connected to the material handling part 44. The design of the material handling guide rail 45 and the material handling slider 46 is to improve the stability when pulling the material bin 7.

[0037] like Figure 5 As shown, a baffle 33 is provided on the feeding rack 3. When the hopper 7 comes into contact with the baffle 33, the hopper 7 is fully inserted into the feeding area 12. The baffle 33 is used to prevent the hopper 7 from being pulled out excessively.
