Description

Technical Field

[0001] This utility model relates to the field of automated feeding, and more specifically, to a disc-shaped feeding device for conveying spherical materials. Background Technology

[0002] In the process of modern industrial automation, the intelligence and efficiency of material handling systems are key to improving overall production efficiency and reducing operating costs. With the deep integration of technology in manufacturing, food processing, pharmaceutical production, and chemical industries, automated production lines have become industry standards. Among these, automated conveying and traying operations for spherical materials (such as bearing balls, candy, capsules, and chemical pellets) are particularly frequent, and the performance of the feeding mechanism directly determines the cycle time and reliability of the production line.

[0003] Despite significant advancements in automated feeding technology, existing specialized feeding systems for spherical materials still suffer from substantial shortcomings, primarily in the following areas: First, at the sorting level, achieving stable and precise single-particle feeding is difficult. The inherent geometric characteristics of spherical materials make them prone to disordered rolling and mutual compression and adhesion during movement. Traditional vibratory feeders or chute-type feeding mechanisms struggle to provide forced and reliable single-particle separation, resulting in multiple materials being supplied to subsequent workstations simultaneously or with intermittent gaps. Second, at the conveying level, flow resistance and turbulence are prone to occur. Due to the high fluidity and easy rolling characteristics of spherical materials, blockages, jams, uneven accumulation, and disordered sorting are easily encountered in the conveying path. These phenomena not only disrupt production continuity, leading to unplanned production line downtime, but can also cause material damage, increasing maintenance costs and quality risks. Finally, at the system integration level, the structure is loose and space utilization efficiency is low. To achieve material sorting and directional output, existing technologies often combine multiple independent devices, resulting in complex system structures, large space occupation, and the connection links between devices further increase the probability of failure and energy consumption. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects (deficiencies) of the prior art and provide a disc-shaped feeding device for conveying spherical materials. It solves the problems that existing special feeding systems for spherical materials are difficult to perform forced and reliable single-material separation of spherical materials, and that material blockage, jamming, uneven accumulation and disordered sorting are prone to occur during the conveying of spherical materials, as well as loose structure and low space utilization.

[0005] The technical solution adopted by this utility model is a disc-shaped feeding device for conveying spherical materials, including a mounting base, a distributing mechanism, a guiding mechanism, and a conveying mechanism. The guiding mechanism includes a base plate, a guide column, and a guide rail. The base plate is fixed on the mounting base and has a discharge port. The guide column is vertically arranged on the base plate. The guide rail is spirally arranged around the guide column and has a head end and an end end, the end of which extends to the base plate and communicates with the discharge port. The distributing mechanism is a ring-shaped columnar structure, coaxially arranged outside the guide column, and can rotate relative to the guiding mechanism and the mounting base. The inner circumferential surface of the distributing mechanism is provided with multiple evenly distributed teeth, and the roots of two adjacent teeth are connected by a concave arc surface. The arc surface and the teeth together form a storage position for accommodating spherical materials.

[0006] When the material distribution mechanism rotates, the teeth on its inner circumferential surface separate the sticky spherical materials and organize the disordered accumulation of spherical materials, allowing them to smoothly enter the storage positions formed by the teeth and the arc surface. Once in the storage positions, the bottom layer of spherical materials in each position falls onto the guide rail. Part of the spherical material remains on the guide rail, while another part extends beyond it, propelled by the teeth. As the distribution mechanism rotates, the teeth push the spherical materials, and simultaneously, under their own gravity, the spherical materials roll downwards along the spirally arranged guide rail. When the material rolls to the end of the guide rail, it is discharged from the outlet due to inertia and conveyed to the next process by the conveying mechanism below the outlet.

[0007] By combining a rotatable dispensing mechanism with a fixed guiding mechanism, sticky spherical materials can be separated and sorted, allowing them to smoothly enter the storage positions, achieving efficient and orderly dispensing and a high degree of automation. As the dispensing mechanism rotates and is guided by the spiral guide rails, the spherical materials in the storage positions are continuously fed out of the outlet in a uniform and evenly spaced manner. Because the dispensing mechanism rotates at a constant speed and each storage position is spatially evenly distributed, the time interval between the delivery of spherical materials is fixed, which is beneficial for subsequent accurate counting and synchronous processing. The structure of the storage positions limits the amount of material they can hold, while the spiral guide rails provide a defined movement path for the materials. This allows the materials to roll orderly under gravity, avoiding the disorderly collisions, bridging, and jamming phenomena commonly found in vibrating silos, fundamentally preventing blockages. The materials are supported by the guide rails and move forward in a rolling manner, resulting in low frictional resistance. The pushing of the teeth and the rolling of the materials under gravity combine naturally, resulting in a smooth and stable movement process, avoiding violent impacts or scraping, effectively reducing wear on the equipment and materials, and extending service life. The material distribution mechanism adopts a ring-shaped columnar structure, with guide rails spirally arranged around the guide columns, resulting in a disc-shaped layout for the entire device. This compact structure maximizes space utilization. This design makes it ideal for integration into modern automated production lines with limited space.

[0008] The guide column has a hollow structure, and the discharge port is located directly below the guide column. This eliminates the need for additional space and structure to guide spherical materials, resulting in a compact structure and high space utilization of the entire device. A clearance hole is provided at the lower end of the guide column to allow spherical materials to pass through. This clearance hole is connected to the end of the guide rail. After the spherical material exits from the end of the guide rail, it enters the hollow guide column through the clearance hole and exits from the discharge port below.

[0009] On the base plate, a first guiding mechanism is installed between the end of the guide rail and the clearance hole. This mechanism guides the spherical material output from the end of the guide rail into the clearance hole, providing a seamless transition path for the spherical material. It smoothly guides the spherical material from the tangential movement of the spirally arranged guide rail to radial movement towards the clearance hole. The first guiding mechanism includes multiple first guide bearings arranged in an arc along a plane parallel to the base plate. The use of an arc-shaped bearing array instead of traditional arc-shaped baffles significantly reduces frictional resistance and surface wear during material turning. Furthermore, the rolling bearings actively receive and deliver the spherical material, effectively absorbing its impact energy and preventing jamming, bouncing, or deviation from the correct path caused by collisions with fixed walls. This ensures high-speed, stable, and reliable material passage at critical turning points, improving the overall conveying efficiency and long-term operational stability of the device.

[0010] A second guiding mechanism is installed above the discharge port to guide spherical materials into the discharge port. This mechanism includes multiple second guide bearings arranged in an arc along a plane perpendicular to the base plate. The arc-shaped openings formed by these bearings face the clearance holes, ensuring that even if the spherical material does not enter the guide column at the ideal angle or position, it can be reliably captured and guided towards the central discharge port, effectively preventing it from impacting the discharge port edge or getting stuck inside the guide column. Furthermore, when spherical material enters the vertical space from a horizontal direction, it is prone to bouncing due to inertial impact against the opposite inner wall, resulting in an unstable descent path. This array of arc-shaped bearings smoothly absorbs the lateral momentum of the spherical material through rolling contact and guides it vertically, ensuring that the material falls in a straight line along a predetermined path.

[0011] The first end of the guide rail is located between its end and the clearance hole. When the storage position rotates to the first end of the guide rail, the bottom layer of spherical material in that storage position is pushed by the teeth and enters the clearance hole from below the first end of the guide rail. The spherical materials above the bottom layer are pushed and rolled to the top of the first end of the guide rail, becoming the new bottom layer of spherical material, ready for the next output. Setting the height P of the first end from the bottom plate and the diameter D of the spherical material to 1.1D ≤ P ≤ 1.2D ensures that only the bottom layer of spherical material in the storage position is pushed into the clearance hole, while the second layer and above spherical materials smoothly roll into the first end of the guide rail, achieving stable and continuous output. If the height P is too small, the spherical material may be stuck between the first end of the guide rail and the bottom plate and cannot smoothly enter the clearance hole. If the height P is too large, the second layer of spherical material cannot roll into the first end of the guide rail.

[0012] At the beginning of the guide rail, a straight section parallel to the base plate is provided, extending to the clearance hole. This ensures that the guide rail is at the same height as the base plate before reaching the clearance hole, facilitating the smooth entry of spherical materials into the clearance hole. Without the straight section, the height of the guide rail from the base plate gradually decreases, and the spherical material may get stuck between the guide rail and the base plate during its entry into the clearance hole, thus preventing it from entering. Alternatively, the height of the beginning of the guide rail may need to be increased to allow the spherical material to enter the clearance hole smoothly.

[0013] The radial width of each storage position of the dispensing mechanism is adapted to the diameter of the spherical material, ensuring that each storage position can only accommodate one spherical material radially. This design fundamentally eliminates radial jamming. If the storage position is too wide radially, multiple spherical materials may simultaneously crowd into one storage position, causing jamming between the dispensing mechanism and the guide column or guide rail, resulting in equipment shutdown. Secondly, it avoids the additional resistance, vibration, and noise generated by the spherical materials squeezing and colliding with each other within the storage position, making the rotation of the dispensing mechanism smoother, the operation of the entire device more reliable, and its lifespan longer. Furthermore, by allowing only the bottommost layer of spherical material in each storage position to be output with each rotation of the dispensing mechanism, and by accommodating only one spherical material radially, only one spherical material is output per rotation of the storage position, facilitating precise control of the output quantity.

[0014] A drive motor is mounted on the mounting base, and a drive gear is mounted on the output shaft of the drive motor. A driven gear is mounted on the material distribution mechanism, and the driven gear meshes with the drive gear. When the drive motor is working, the drive gear rotates, driving the driven gear meshing with it to rotate, thereby realizing the rotation of the material distribution mechanism relative to the mounting base and the guide mechanism. Compared with chain drives or synchronous belt drives, gear drives have higher precision, can withstand larger loads, and can achieve a more compact structural layout in terms of space adaptability.

[0015] To prevent spherical materials from accumulating in the central area, a conical surface is provided at the top of the guide column to provide a smooth ramp, guiding the spherical materials to slide naturally and smoothly to the surrounding areas and smoothly enter the storage position.

[0016] When the material separating mechanism rotates, the teeth contact the spherical materials, thereby separating the spherical materials that are stuck together and pushing them to roll along the guide track. To avoid the right-angled edges formed on the teeth damaging the surface of the spherical materials, the side of the teeth facing the guide post is made into an arc surface to make the contact between the teeth and the spherical materials smoother. Compared with existing technologies, the advantages of this invention are as follows: By cooperating with a rotatable dispensing mechanism and a fixed guiding mechanism, mutually adhering spherical materials can be separated and sorted, allowing them to smoothly enter the storage positions, achieving efficient and orderly dispensing and a high degree of automation. Because the dispensing mechanism rotates at a uniform speed, and each storage position is evenly distributed in space, when the dispensing mechanism rotates, the spherical materials are pushed by the teeth and roll along the guide rail. Their speed is uniform, their arrangement is orderly, and the movement is smooth and stable, avoiding violent impacts or scratches, effectively reducing wear on the equipment and materials. Furthermore, the initial velocity of the spherical materials when output from the end of the rail is the same, preventing some spherical materials from having a higher initial velocity than others, thus avoiding phenomena such as squeezing, collision, or jamming of multiple spherical materials. The dispensing mechanism adopts a ring-shaped columnar structure, with the guide rail spirally arranged around the guide column. The entire device has a disc-shaped layout, a compact structure, and high space utilization. To avoid damaging the surface of the spherical material during separation and pushing, the side of the tooth facing the guide post is designed with an arc shape to ensure smoother contact between the tooth and the spherical material. The guide post is hollow, and the discharge port is located directly below it, eliminating the need for additional space or structure to guide the spherical material. A first guiding mechanism is installed between the end of the guide rail and the clearance hole to guide the spherical material output from the end of the guide rail into the clearance hole. The first guiding mechanism includes multiple first guide rail bearings arranged in an arc along a plane parallel to the base plate. These bearings actively receive and deliver the spherical material, effectively absorbing its impact energy and preventing jamming, bouncing, or deviation from the correct path caused by collision with the fixed wall. This ensures high-speed, stable, and reliable passage of the material at critical turning points. A second guiding mechanism is installed above the discharge port to guide the spherical material into the discharge port, preventing it from impacting the edge of the discharge port or getting stuck on the inner wall of the guide post. The second guiding mechanism includes multiple second guide bearings arranged in an arc along a plane perpendicular to the base plate, with the arc opening facing the clearance hole. This arc-shaped bearing array reliably captures and guides spherical material into the discharge port, smoothly absorbing the lateral momentum of the spherical material through rolling contact and guiding it vertically. A vertical guide channel is provided below the discharge port to provide material constraint for the spherical material leaving the discharge port, forcing it to fall along a predetermined vertical path and preventing it from leaving the discharge port at an undesirable angle, orientation, or with lateral velocity. The first end of the guide rail is located between its end and the clearance hole, and the height P of the first end from the base plate satisfies the condition 1.1D ≤ P ≤ 1.2D with respect to the diameter D of the spherical material. This ensures that when the storage position rotates to the first end of the guide rail, only the bottommost layer of spherical material enters the clearance hole from below the first end of the guide rail, while the uppermost layer rolls to the top of the first end of the guide rail.The guide rail has a straight section at its beginning that extends to a clearance hole, ensuring a uniform height from the beginning to the clearance hole and preventing spherical materials from getting stuck. To fundamentally eliminate radial jamming of spherical materials within the storage compartment, the radial width of each storage compartment is set to match the diameter of the spherical material, allowing each compartment to accommodate only one spherical material radially. Gear drive is employed, offering advantages such as high precision, high load capacity, compact structure, and strong spatial adaptability. To prevent material accumulation in the central area, a tapered surface is provided at the top of the guide column to guide the spherical material smoothly into the storage compartment.

[0029] like Figures 1-3 As shown, a device for conveying spherical materials is characterized by comprising a mounting base 1, a distributing mechanism 2, and a guiding mechanism 3. The guiding mechanism 3 includes a base plate 31, a guide column 32, and a guide rail 33. The base plate 31 is fixed on the mounting base 1 and has a discharge port 311. The guide column 32 is vertically disposed on the base plate 31. The guide rail 33 is spirally disposed around the guide column 32 and has a head end 331 and an end end 332. The end end 332 extends to the base plate 31 and communicates with the discharge port 311. The distributing mechanism 2 is an annular columnar structure, coaxially disposed outside the guide column 32, and can rotate relative to the guiding mechanism 3 and the mounting base 1. The inner circumferential surface of the distributing mechanism 2 is provided with a plurality of evenly distributed teeth 21, and the roots of two adjacent teeth 21 are connected by a concave arc surface 22. The arc surface 22 and the teeth 21 together form a storage position 4 for accommodating spherical materials.

[0030] Specifically, such as Figures 3-5 As shown, the base plate 31 is circular and fixed to the mounting base 1. Its edge is provided with an upwardly extending baffle 312, and the discharge port 311 is located in its central area. The guide column 32 is a hollow columnar structure, located on the base plate 31, directly above the discharge port 311. Its bottom is open, and its top has a conical surface 321. The conical surface 321 guides spherical materials into the storage position 4, preventing accumulation in the central area. A clearance hole 322 is provided on the side wall at the lower end of the guide column 32. The clearance hole 322 communicates with the end 332 of the guide rail 33. After the spherical material exits from the end 332 of the guide rail 33, it enters the interior of the guide column 32 through the clearance hole 322 and exits from the discharge port 311 below it. Figure 3 As shown, the guide rail 33 is spirally arranged around the outer surface of the guide post 32. Its first end 331 is located between the end 332 of the guide rail 33 and the clearance hole 322. The height P of the first end 331 from the base plate 31 satisfies 1.1D ≤ P ≤ 1.2D with respect to the diameter D of the spherical material (here, the height P of the first end 331 from the base plate 31 does not include the thickness of the guide rail 33). The first end 331 of the guide rail 33 is provided with a straight section 333, which is parallel to the base plate 31. The height of the straight section 333 from the base plate 31 is the same as the height P of the first end 331 from the base plate 31. The width B of the guide rail 33 is 0.4-0.6 times the diameter D of the spherical material. The width B of the guide rail 33 is the distance from the side of the guide rail 33 away from the guide post 32 (the edge of the guide rail) to the guide post 32.

[0031] like Figure 3 As shown, a first guiding mechanism 34 is provided on the base plate 31. The first guiding mechanism 34 is located between the end 332 of the guide rail 33 and the clearance hole 322, and is used to guide the spherical material output from the end 332 into the clearance hole 322. The first guiding mechanism includes a plurality of first guide bearings 341 arranged in an arc along a plane parallel to the base plate 31. Figure 4 As shown, a second guiding mechanism 35 is also provided above the discharge port 311 to guide spherical material into the discharge port 311. The second guiding mechanism includes multiple second guide bearings 351 arranged in an arc along a plane perpendicular to the base plate 31, and the arc-shaped opening formed by the multiple second guide bearings 351 faces the clearance hole 322. When the spherical material is output from the end 332 of the guide rail 33, it is guided by the first guiding mechanism 34 into the clearance hole 322, and then guided by the second guiding mechanism 35 to be output from the discharge port 311. Below the discharge port 311, a vertical guiding channel 313 is provided to force the spherical material to fall along a predetermined vertical path.

[0032] like Figure 1 , Figure 6 As shown, the material distribution mechanism 2 is coaxially arranged with the guide post 32 and located outside the guide post 32, with its inner circumferential surface forming an annular region with the guide post 32. Multiple evenly distributed teeth 21 are provided on the inner circumferential surface of the material distribution mechanism 2. The side of the teeth 21 facing the guide post 32 is set as an arc-shaped surface 211, making the contact between it and the spherical material smoother and avoiding damage to the surface of the spherical material when pushing it. The storage position 4 formed by the teeth 21 and the arc surface 22 is used to accommodate the spherical material. The width of the storage position 4 in the radial direction of the material distribution mechanism 2 is adapted to the diameter D of the spherical material, so that each storage position 4 can only accommodate one spherical material in the radial direction. Figure 6 , Figure 7 As shown, preferably, the ratio of the radius R1 of the arc surface 22 to the radius R of the spherical material is 1.0-1.2, so that the curvature of the arc surface 22 matches the contour height of the spherical material. The maximum distance H1 between the arc surface 22 and the guide post 32 is 1.1-1.3 times the diameter D of the spherical material, so that the spherical material can smoothly enter the storage position 4. A gap is left between the tooth 21 and the guide rail 33 to avoid interference and ensure that the dispensing mechanism 2 can rotate relative to the guide mechanism 3. Therefore, the minimum distance H between the tooth 21 and the guide post 32 is slightly larger than the width B of the guide rail 33. Preferably, the minimum distance H between the tooth 21 and the guide post 32 is 0.5-0.7 times the diameter D of the spherical material. This distance ensures that even when the spherical material is in close contact with the guide post 32, the tooth 21 can reliably push the spherical material along the guide rail 33, rather than pushing it into the jamming area. In the radial direction, the maximum distance G between the side of the guide rail 33 away from the guide post (the edge of the guide rail) and the arc surface 22 is less than 0.6 times the diameter D of the spherical material. This distance G ensures that the spherical material can be smoothly pushed by the teeth 21 even when it is in close contact with the arc surface 22, without getting stuck between the edge of the guide rail 33 and the arc surface 22. When the spherical material is in the storage position 4, its position is uncertain; it may be in close contact with the guide post 32 or the arc surface 22. Through the above-mentioned dimensional limitation, it can be ensured that the spherical material can be smoothly pushed by the teeth 21, so that it will not get stuck between the teeth 21 and the guide post 32, nor between the arc surface 22 and the edge of the guide rail 32.

[0033] Preferably, the storage position 4, located axially in the distribution mechanism 2, can accommodate 2-3 spherical materials. After the bottom layer of spherical material is output, the upper layers of spherical material fall down layer by layer under gravity to replenish it, forming a stable and sustainable material flow. This is beneficial for improving efficiency and continuity. However, the number of layers should not be too large; otherwise, the pressure on the bottom layer of spherical material will be too high, increasing friction and leading to increased rotational resistance of the distribution mechanism 2, as well as increased surface wear of the spherical material. It is understood that the storage position 4, located axially in the distribution mechanism 2, can also accommodate only one spherical material.

[0034] like Figure 8As shown, a first bearing 212 is provided at the bottom of each of the prying teeth 21. The height of the first bearing 212 from the base plate 31 is set according to the diameter D of the spherical material. The material distribution mechanism 2 is located above the enclosure 312 of the base plate 31. Therefore, the bottom of the prying teeth 21 will be at a certain height from the base plate 31. When the spherical material rolls to a lower position on the guide rail 33 or onto the base plate 31, the bottom of the prying teeth 21 may come into contact with the spherical material, scraping it or even causing it to get stuck between the bottom of the prying teeth 21 and the base plate 31. The first bearing 212 at the bottom of the prying teeth 21 reduces the friction on the spherical material by utilizing its rolling motion. The height of the first bearing 212 from the base plate 31 is set according to the diameter D of the spherical material to ensure that the spherical material can contact the first bearing 212.

[0035] like Figure 2 As shown, the material distribution mechanism 2 is equipped with a driven gear 23, and the mounting base 1 is equipped with a drive motor 11. The output shaft of the drive motor 11 is equipped with a driving gear 12, and the driving gear 12 meshes with the driven gear 23. When the drive motor 11 is working, the driving gear 12 rotates, driving the driven gear 23 meshing with it to rotate, thereby enabling the material distribution mechanism 2 to rotate relative to the mounting base 1 and the guide mechanism 3.

[0036] like Figure 2 , Figure 8 As shown, to enable the material distribution mechanism 2 to rotate relative to the mounting base 1 and the guide mechanism 3, a movement clearance is left between the material distribution mechanism 2 and the mounting base 1 and the guide mechanism 3, which causes the material distribution mechanism 2 to produce radial runout or wobbling during rotation. The device has multiple second bearings 13 installed on the mounting base 1. These second bearings 13 are evenly distributed along the outer circumferential surface of the material distribution mechanism 2 and contact the outer circumferential surface of the material distribution mechanism 2, thereby providing radial constraint on the material distribution mechanism 2, suppressing its radial runout and wobbling during rotation, ensuring that the relative position between the tooth 21 and the spherical material and the guide rail 33 remains accurate, and improving the stability and reliability of material distribution and conveying.

[0037] like Figure 9 As shown, a material tray 5 is provided above the material distribution mechanism 2 and the guiding mechanism 3. The material tray 5 is funnel-shaped and is used to guide and gather spherical materials into the annular area formed by the material distribution mechanism 2 and the guiding column 32. At the same time, the material tray 5 can hold a certain number of spherical materials to form a material pile, ensuring that the device has a continuous source of materials without the need for frequent feeding.

[0038] Below the discharge port 311, a conveying mechanism (not shown) is also provided for conveying the spherical material output from the discharge port 311.
