Description

Technical Field

[0001] This invention relates to the field of automated equipment technology, and more specifically, to a material dispersing and conveying system and method. Background Technology

[0002] In many industrial sectors such as food, chemicals, and building materials, bagged materials are a common form of material storage and transfer. The packaging process is crucial for ensuring the safe storage and efficient transportation of these materials. Typically, after bagged materials are metered and filled into bags of fixed specifications, they need to be manually or automatically packed into turnover boxes or transport containers according to a preset arrangement. Once the packaging is complete, it is easy to stack and store the materials through a warehousing system or transport them to downstream customers through a logistics network. The entire packaging process directly affects the efficiency of material flow and cost control.

[0003] To improve the utilization of space within transport containers and avoid irregular bag shapes caused by uneven material distribution and localized overlap, which could lead to gaps during stacking, existing technologies typically add a material dispersing process before the bagged materials enter the conveyor belt. This process uses mechanical vibration, stirring, or manual assistance to disperse the material into a uniform distribution, ensuring the bags maintain a regular shape before being transported to the transport container for stacking. However, this dispersing process prolongs the overall packing cycle, and the coordination between the dispersing operation and the conveyor belt transport requires additional equipment and manpower. This not only increases operational complexity but also significantly reduces overall packing efficiency, making it difficult to meet the demands for efficient transport of bagged materials in large-scale production scenarios. Summary of the Invention

[0004] To address the problem of low efficiency in the process of breaking down and conveying bagged goods, this invention provides a material breaking down and conveying system and method.

[0005] In a first aspect, this application proposes a material dispersing and conveying system, comprising:

[0006] A bagged item, comprising a bag body and a plurality of flexible adhesives; the flexible adhesives are sealed within the bag body.

[0007] Multiple first rollers, each first roller having a polygonal outer contour in its cross-section along its radial direction; the multiple first rollers are arranged sequentially along the feeding direction;

[0008] The working state of the material dispersing and conveying system includes the bagged material on the first roller, and multiple first rollers rotating around their own axes to drive the bagged material to move along the feeding direction; wherein, during the movement of the bagged material on the first roller, adjacent soft adhesives move relative to each other.

[0009] In some embodiments, the material dispersing and conveying system further includes a second conveying assembly; the second conveying assembly includes a short conveying unit and a long conveying unit; the long conveying unit includes a long conveyor belt and a plurality of stops; the first roller, the short conveying unit, and the long conveyor belt are arranged sequentially along the feeding direction; the stops are connected to the long conveyor belt; the plurality of stops are arranged at intervals along the length direction of the long conveyor belt; the spacing between adjacent stops along the length direction of the long conveyor belt is greater than or equal to the size of the bagged material in the first preset state along the feeding direction; the height difference between the top surface of the long conveyor belt and the top surface of the short conveying unit is within a second preset range; wherein, the maximum height difference between the top surfaces of the bagged material in the first preset state is within the first preset range;

[0010] The working states include a first state and a second state; the first state includes the first roller moving the bagged item onto the short conveyor unit, the short conveyor unit being stationary, and the stop moving along the feeding direction; the second state includes the first roller moving the bagged item onto the short conveyor unit, the short conveyor unit moving the bagged item between two adjacent stops, and the bagged item moving along the feeding direction with the long conveyor belt.

[0011] In some embodiments, the linear velocity of the outer peripheral surface of the first roller in the first region rotating about the axis of the first roller is a first velocity; the linear velocity of the outer peripheral surface of the first roller in the second region rotating about the axis of the first roller is a second velocity; wherein the first velocity is less than the second velocity, the first roller farther away from the second conveying assembly is the first roller in the first region, and the first roller closer to the second conveying assembly is the first roller in the second region.

[0012] In some embodiments, the first region includes a first front region and a first rear region; the first front region, the first rear region, and the second region are arranged sequentially along the feeding direction; the linear velocity of the outer peripheral surface of the first roller in the first front region rotating around the axis of the first roller is a third velocity; the linear velocity of the outer peripheral surface of the first roller in the first rear region rotating around the axis of the first roller is a fourth velocity; wherein, the fourth velocity is less than the third velocity and the fourth velocity is less than the second velocity.

[0013] In some embodiments, the material dispersing and conveying system further includes a second roller; the outer contour of the cross-section of the second roller along its own radial direction is polygonal; at least two first rollers are arranged between two adjacent second rollers; the rotation direction of the second roller about its own axis is opposite to the rotation direction of the first roller about its own axis; the speed at which the outer circumferential surface of the second roller rotates about the axis of the second roller is less than or equal to the speed at which the outer circumferential surface of the first roller rotates about the axis of the first roller.

[0014] In some embodiments, the second roller is disposed between the first rollers in the first region.

[0015] In some embodiments, α1 > α2; α3 > α2; where α1 is the minimum included angle between two adjacent faces of the first roller in the first region in its own rotation direction, α2 is the minimum included angle between two adjacent faces of the first roller in the second region in its own rotation direction, and α3 is the minimum included angle between two adjacent faces of the second roller in the first region in its own rotation direction.

[0016] In some embodiments, A > C; B > C; where A is the distance between adjacent first rollers in the first region along the feeding direction; B is the distance between adjacent first rollers and second rollers in the first region along the feeding direction; and C is the distance between adjacent first rollers in the second region along the feeding direction.

[0017] In some embodiments, the top surface of the first roller closer to the second conveying assembly is higher than the top surface of the first roller farther from the second conveying assembly.

[0018] Secondly, this application proposes a material dispersing and conveying method, which is applied to any of the material dispersing and conveying systems described in the first aspect. The material dispersing and conveying method includes:

[0019] The bagged item is moved to the first vibration unit; wherein the bagged item includes a bag body and a plurality of soft adhesives; the soft adhesives are sealed inside the bag body;

[0020] The first vibration unit has multiple first rollers that rotate around their own axis to drive the bagged material to move along the feeding direction; wherein, the outer contour of the cross section of the first roller along its own radial direction is polygonal; the multiple first rollers are spaced apart; during the movement of the bagged material on the first roller, the adjacent soft adhesives move relative to each other.

[0021] In some embodiments, during at least a portion of the process in which the plurality of first rollers of the first vibration unit rotate about their own axis to drive the bagged material to move along the feeding direction, the second roller of the material dispersing and conveying system rotates about its own axis and abuts against the bag; wherein the rotation direction of the first rollers is opposite to that of the second rollers.

[0022] To solve the problem of uneven distribution of lumps inside bagged materials during packaging, this invention has the following advantages:

[0023] The material dispersing and conveying system, consisting of bagged goods and multiple first rollers, operates by placing the bagged goods on the first rollers. The multiple first rollers rotate around their own axes, driving the bagged goods to move along the feeding direction. During this movement, adjacent soft, sticky parts of the bagged goods move relative to each other. This allows the distance from the top surface of the polygonal first roller to the axis to change with the rotation angle, causing the bagged goods to experience slight up-and-down bumps or slight left-and-right swaying. This force is transmitted to the soft, sticky parts inside the bag, causing them to separate and move. Simultaneously, the multiple first rollers arranged sequentially along the feeding direction ensure that the bagged goods are continuously subjected to this bumping action throughout the conveying process, avoiding the ineffectiveness of a single action. This method effectively addresses the issue of uneven dispersion in certain areas, ensuring the stability and thoroughness of the soft adhesive dispersion effect. This results in a uniform distribution of the soft adhesive within the bag and a more regular overall bag shape. Consequently, the bagged materials can be tightly and neatly stacked during subsequent boxing, significantly reducing gaps between bags and preventing uneven stress on the box caused by irregular bag shapes. Ultimately, this solves the technical problems of poor boxing results, low utilization of internal space in the box, increased packaging material consumption and transportation costs, and easy deformation, damage, and scattering of bagged materials during transportation or stacking caused by uneven distribution of the soft adhesive within the bagged material. This ensures the safety and stability of material transfer. Attached Figure Description

[0035] To improve space utilization within transport containers and prevent irregular bag shapes caused by uneven material distribution, which could lead to gaps during stacking, existing technologies typically add a material dispersing process before the bags enter the conveyor belt. This process uses mechanical vibration, stirring, or manual assistance to ensure a uniform material distribution and a regular bag shape. However, this dispersing process directly extends the overall packaging cycle. Furthermore, the coordination between the dispersing operation and the subsequent conveyor belt transport requires additional equipment and manpower, increasing operational complexity and significantly reducing overall packaging efficiency. Ultimately, this fails to meet the actual needs of efficient bagged material transportation in large-scale production scenarios.

[0036] Example 1:

[0037] This embodiment discloses a material dispersing and conveying system, such as Figure 2 and Figure 4 As shown, the material dispersing and conveying system includes a bagged item 50 and multiple first rollers 212. The bagged item 50 includes a bag body 51 and multiple soft adhesives 52; the soft adhesives 52 are sealed inside the bag body 51. The outer contour of the cross-section of each first roller 212 along its radial direction is polygonal; multiple first rollers 212 are arranged sequentially along the feeding direction. When the polygonal rollers rotate, the distance from the top surface to the axis changes with the rotation angle, causing the bagged item 50 to experience slight up-and-down bumps or slight left-and-right swaying. This force can be transmitted to the soft adhesives 52 inside the bag, pushing the originally aggregated soft adhesives 52 to separate and move. The multiple rollers arranged sequentially along the feeding direction ensure that the bagged item 50 is continuously subjected to bumping action throughout the conveying process, avoiding the problem of local undispersed areas caused by insufficient action in a single instance, and ensuring the stability and thoroughness of the dispersion effect of the soft adhesives 52.

[0038] The material dispersing and conveying system operates by having bagged goods 50 move along the feeding direction via multiple first rollers 212 rotating around their own axes. During this movement, the bagged goods 50, under their own weight and the vibrations caused by the rollers, cause relative movement of adjacent soft, sticky materials 52 within the bag. This minimizes vertical overlap of the soft, sticky materials 52, ensuring even distribution within the bag and resulting in a more regular bag shape. This process simultaneously disperses the soft, sticky materials 52 within the bag while conveying the bagged goods 50, improving the efficiency of the dispersing and conveying process. Furthermore, the regular bag shapes 51 allow for tight stacking with minimal gaps during subsequent boxing, improving the utilization of internal space and preventing uneven stress on the box caused by irregular bag shapes, thus ensuring safe transport.

[0039] In other embodiments, the outer contour of the cross section of the first roller 212 along its own radial direction can also be circular. The first roller 212 drives the bag 50 to produce small up-and-down bumps or slight left-and-right swaying by eccentric rotation.

[0040] Furthermore, such as Figure 2As shown, the material dispersing and conveying system also includes a second conveying component 30; the second conveying component 30 includes a short conveying unit 31 and a long conveying unit 32; the long conveying unit 32 includes a long conveyor belt 322 and multiple stops 323; the first roller 212, the short conveying unit 31, and the long conveyor belt 322 are arranged sequentially along the feeding direction; the stops 323 are connected to the long conveyor belt 322; the multiple stops 323 are arranged at intervals along the length of the long conveyor belt 322; the spacing between adjacent stops 323 along the length of the long conveyor belt 322 is greater than or equal to the size of the bagged material 50 in the first set state along the feeding direction. The multiple stops 323 are arranged at intervals along the long conveyor belt 322, and one bagged material 50 in the first set state can be accommodated between each two adjacent stops 323 in the feeding direction, which can prevent the bagged materials 50 from colliding, squeezing, or stacking with each other during conveying, and ensure that the shape of the bagged materials 50 is not damaged; the height difference between the top surface of the long conveyor belt 322 and the top surface of the short conveyor unit 31 is within a second set range. The second setting range limits the smoothness of the connection between the short conveyor unit 31 and the long conveyor unit 32, which can avoid unstable conveying caused by a large height difference between the top surface of the long conveyor belt 322 and the top surface of the short conveyor unit 31. The second setting range can be 0mm to 20mm. In the first setting state, the maximum height difference between the top surfaces of the bagged items 50 is within the first setting range. The first setting state limits the bagged items 50 to be in a uniformly dispersed state, ensuring that all bagged items 50 entering the second conveying assembly 30 meet the requirements for subsequent conveying and packing, and preventing unqualified materials from flowing into the next stage. The first setting range can be 0mm to 15mm, and the first setting range can be reset according to the actual size of the bagged items.

[0041] The working states include a first state and a second state. In the first state, the first roller 212 moves the bagged item 50 onto the short conveyor unit 31, the short conveyor unit 31 remains stationary, and the stop block 323 moves along the feeding direction. In the second state, the first roller 212 moves the bagged item 50 onto the short conveyor unit 31, the short conveyor unit 31 moves the bagged item 50 between two adjacent stop blocks 323, and the bagged item 50 moves along the feeding direction with the long conveyor belt 322. The short conveyor unit 31 can adjust the conveying timing of the bagged item 50 according to the position rhythm of the stop blocks 323 on the long conveyor belt 322. Thus, when the stop block 323 is not in position, the short conveyor unit 31 remains stationary, temporarily storing the bagged item 50; when the stop block 323 is in position, creating an empty space, the short conveyor unit 31 starts and smoothly feeds the bagged item 50 between two adjacent stop blocks 323. This avoids interference between the bagged item 50 and the stop block 323, preventing jamming or damage to the shape of the inner soft adhesive 52, thus improving overall conveying efficiency.

[0042] Furthermore, the linear velocity of the outer circumference of the first roller 212 in the first region rotating around the axis of the first roller 212 is the first velocity; the linear velocity of the outer circumference of the first roller 212 in the second region rotating around the axis of the first roller 212 is the second velocity; wherein, the first velocity is less than the second velocity, the first roller 212 farther away from the second conveying assembly 30 is the first roller 212 in the first region, and the first roller 212 closer to the second conveying assembly 30 is the first roller 212 in the second region. The first region is the region where the bagged material 50 enters the dispersing stage, and the lower first velocity provides sufficient time for the separation of the soft adhesive 52. The speed in the second region is faster, which allows the soft adhesive 52 to displace in the opposite direction of the feeding direction within the bag body 51 due to inertia. When the bagged material 50 is conveyed to the short conveyor belt 312 and stops, the soft adhesive 52 will displace in the feeding direction within the bag body 51 due to inertia, resulting in a uniform distribution of the soft adhesive 52 within the bag body 51. Moreover, as the end of the dispersing process and the transition area connecting the second conveying component 30, the higher second speed of the second area can match the downstream conveying rhythm.

[0043] Furthermore, the first region includes a first front region and a first rear region; the first front region, the first rear region, and the second region are arranged sequentially along the feeding direction; the linear velocity of the outer circumference of the first roller 212 in the first front region rotating around the axis of the first roller 212 is the third velocity; the linear velocity of the outer circumference of the first roller 212 in the first rear region rotating around the axis of the first roller 212 is the fourth velocity; wherein, the fourth velocity is less than the third velocity, and the fourth velocity is less than the second velocity. When the bagged material 50 first enters the system, there may be many soft, sticky materials 52 adhering to each other to form a whole, i.e., a large aggregated state. The polygonal roller at the third velocity can provide more intense vibration to the soft, sticky materials 52 through a faster rotation frequency, quickly breaking up the large aggregated state of the soft, sticky materials 52, so that the soft, sticky materials 52 do not overlap in their own height direction under the action of vibration, quickly forming the bagged material 50 in the first set state. At the same time, the faster conveying speed can quickly receive the bagged material 50 sent from upstream, avoiding material accumulation at the system inlet.

[0044] In addition, due to the higher speed in the second zone, when the bagged item 50 is conveyed from the first rear zone to the second zone, the soft adhesive 52 will be displaced in the opposite direction of the feeding direction within the bag body 51 due to inertia. Then, when the bagged item 50 is conveyed to the short conveyor belt 312 and stops, the soft adhesive 52 will be displaced in the feeding direction within the bag body 51 due to inertia, so that the soft adhesive 52 is evenly distributed within the bag body 51.

[0045] Furthermore, the material dispersing and conveying system also includes a second roller 222; the outer contour of the cross-section of the second roller 222 along its own radial direction is polygonal; at least two first rollers 212 are arranged between two adjacent second rollers 222; the rotation direction of the second roller 222 around its own axis is opposite to the rotation direction of the first roller 212 around its own axis; the rotation speed of the outer circumference of the second roller 222 around its axis is less than or equal to the rotation speed of the outer circumference of the first roller 212 around its axis. The second roller 222 adopts a rotation direction opposite to that of the first roller 212, and the combined force of the second roller 222 and the first roller 212 on the bagged material 50 results in more intense vibration of the bagged material 50, enhancing the dispersing effect, thereby further enabling the soft adhesive 52 to be evenly distributed inside the bag, making the overall shape of the bag 51 more regular.

[0046] Furthermore, the second roller 222 is positioned between the first rollers 212 in the first region. The first region is the core area where the soft adhesive 52 inside the bag 50 gathers into a first set state. Positioning the second roller 222 here can specifically address the problem of large-scale aggregation of the bag 50 without interfering with the function of other regions. If the second roller 222 is positioned in the second region, excessive vibration may cause the soft adhesive 52 to stack when the bag 50 is conveyed from the first rear region to the second region, due to inertia and displacement in the opposite direction of the feeding direction within the bag body 51.

[0047] Furthermore, such as Figure 5 and Figure 6 As shown, α1 > α2; α3 > α2; where α1 is the minimum included angle between two adjacent faces of the first roller 212 in the first region along its own rotation direction, α2 is the minimum included angle between two adjacent faces of the first roller 212 in the second region along its own rotation direction, and α3 is the minimum included angle between two adjacent faces of the second roller 222 in the first region along its own rotation direction. The smaller the minimum included angle between two adjacent faces, the closer the cross-sectional profile of the roller is to a circle, and the gentler the force exerted on the bagged material 50; conversely, the larger the minimum included angle, the greater the force exerted on the bagged material 50. The first region is the core area for the soft adhesive 52 inside the bagged material 50 to go from aggregation to the first set state. The larger amplitude of the bumps brought by α1 and α3, combined with the speed design of the first region, can quickly break up large clumps of soft adhesive 52 in the first region, avoiding incomplete dispersal due to insufficient bumps. The first roller 212 in the second region has a smaller α2 and a smoother profile. Its height changes more slowly and with a smaller amplitude during rotation, which greatly reduces the turbulence on the bagged item 50. This allows the soft adhesive 52 to be distributed more evenly, ensuring that the bagged item 50 enters the short conveyor unit 31 in a regular shape.

[0048] If α2 > α1 or α2 > α3, excessive vibration may cause the soft adhesive 52 to stack in the bag body 51 due to inertia as it is conveyed from the first rear area to the second area.

[0049] Further, A > C; B > C; where A is the spacing between adjacent first rollers 212 along the feeding direction in the first region (two adjacent first rollers 212 are two first rollers 212 without a second roller 222 in between); B is the spacing between adjacent first rollers 212 and second rollers 222 along the feeding direction in the first region; and C is the spacing between adjacent first rollers 212 along the feeding direction in the second region. A larger spacing allows for a larger concave area of ​​the bagged item 50 between two adjacent first rollers 212 or between adjacent first rollers 212 and second rollers 222 in the first region. When the concave portion of the bagged item 50 moves onto the first rollers 212 and second rollers 222, it will be lifted by the first rollers 212 and second rollers 222. This height difference generates greater vibration force, and the turbulence force generated by the roller rotation can more fully act on the inside of the bag body 51, avoiding incomplete dispersal of the bagged item 50 due to excessively dense rollers. The spacing between adjacent first rollers 212 in the second region is small. When the bag 50 moves at high speed, there are always multiple rollers supporting the bottom, which can prevent the bag 51 from shaking or deforming due to insufficient support, or the soft adhesive 52 from gathering again due to heavy shaking.

[0050] Furthermore, in the second region, the top surface of the first roller 212 near the second conveying assembly 30 is higher than the top surface of the first roller 212 away from the second conveying assembly 30. In this way, the top surface of the first roller 212 in the second region forms a slope, and the soft adhesive 52 generates a downward gravitational force along the slope, which can make the soft adhesive 52 move a certain distance in the opposite direction of the feeding direction. When the bagged material 50 moves to the second conveying assembly 30 and stops, the soft adhesive 52 will move a certain distance again in the feeding direction due to inertia. After the gravity and inertia brought by the slope reach equilibrium, the soft adhesive 52 can be evenly distributed in the bag body 51.

[0051] In other embodiments, such as Figure 1 As shown, the material dispersing and conveying device includes a first conveying assembly 10; the first conveying assembly 10 includes a first drive unit 11 and a first conveyor belt 12; the first drive unit 11 is driven to connect with the first conveyor belt 12; the first drive unit 11 drives the first conveyor belt 12 to convey the bagged material 50 to be dispersed onto the first roller 212. The first conveyor belt 12, as a continuous conveying carrier, can directly receive the bagged material 50 sent from upstream, avoiding the tipping and stacking of the bagged material 50 caused by manual handling or random stacking, and ensuring that each bagged material 50 enters the first roller 212 in a set posture.

[0052] In other embodiments, the material dispersing and conveying device includes a vibrating conveying assembly 20, which includes a first vibrating unit 21 and a second vibrating unit 22. The first vibrating unit 21 includes a second driving part 211 and a first roller 212. The second vibrating unit 22 includes a third driving part and a second roller 222. The second driving part 211 is drivenly connected to the first roller 212, and the third driving part is drivenly connected to the second roller 222.

[0053] In other embodiments, the short conveying unit 31 includes a fourth drive unit 311 and a short conveyor belt 312; the long conveying unit 32 includes a fifth drive unit, a long conveyor belt 322, and stop blocks 323. The fourth drive unit 311 is drivenly connected to the short conveyor belt 312; the fifth drive unit is drivenly connected to the long conveyor belt 322; and multiple stop blocks 323 are arranged at intervals along the length of the long conveyor belt 322.

[0054] In other embodiments, such as Figure 3 As shown, the material dispersing and conveying device includes a handling component 40 and a housing 60; the handling component 40 includes a robot arm 41 and a suction cup 42. The robot arm 41 is driven to connect with the suction cup 42; the robot arm 41 drives the suction cup 42 to pick up the bagged items 50 on the long conveyor belt 322 and transport them to the housing 60.

[0055] Example 2:

[0056] This embodiment provides a material dispersing and conveying method, which can be applied to any of the material dispersing and conveying devices in Embodiment 1, such as... Figure 7 As shown, the material dispersing and conveying method may include:

[0057] Step S10: The bagged material 50 is moved onto the first vibration unit 21; wherein, the bagged material includes a bag body 51 and a plurality of soft adhesives 52; the soft adhesives 52 are sealed inside the bag body 51; providing a basis for the subsequent dispersing operation.

[0058] Step S20: Multiple first rollers 212 of the first vibration unit 21 rotate around their own axes, driving the bagged material 50 to move along the feeding direction; wherein, the outer contour of the cross-section of the first roller 212 along its own radial direction is polygonal; multiple first rollers 212 are spaced apart; during the movement of the bagged material 50 on the first roller 212, adjacent soft adhesives 52 move relative to each other. Through the continuous rotation of the rollers, the soft adhesives 52 change from a locally piled state to a mutually separated and uniformly dispersed state, thereby solving the problem of irregular shape of the bag 51 caused by uneven distribution of lumps, thus facilitating the subsequent boxing work of the bagged material.

[0059] Furthermore, in at least a portion of step S20, the second roller 222 of the material dispersing and conveying system rotates around its own axis and abuts against the bag body 51; wherein the rotation direction of the first roller 212 is opposite to that of the second roller 222. The first roller 212 rotates along the feeding direction and applies a vibrational force in another direction to the bagged material 50 through its polygonal structure, which can further push the soft adhesive 52 to disperse along the conveying direction, improve the efficiency of the dispersion of the soft adhesive 52 in the bag body 51, and provide a stable foundation for the subsequent entry of the bagged material 50 into the second conveying assembly 30.

[0060] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
