[0049] In modern logistics, warehousing, and various manufacturing scenarios, the efficient and stable transport of goods is a crucial element in ensuring the smooth operation of the entire process. Conveyor belt-chute combinations are widely used for transferring goods from one location to another due to their relatively simple structure and low cost.

[0050] However, this seemingly conventional method of transmission has revealed many serious drawbacks in actual operation.

[0051] When goods on the conveyor belt are transferred to the chute, their weight has a significant adverse impact on the conveying process. For heavier goods, their greater weight results in greater inertia and impact forces as they slide within the chute. This causes the heavy object to sequentially collide with the left and right side walls of the chute, generating substantial friction and collision forces. These forces can uncontrollably alter the object's motion, greatly increasing the risk of it stopping within the chute. Even if the object doesn't completely stop, repeated collisions and friction with the side walls can cause it to deviate from its normal trajectory, preventing it from smoothly exiting the chute and leading to blockages. This severely impacts the efficiency of the entire conveyor system.

[0052] Lighter goods face similar challenges. Despite their lower weight, they are easily affected by airflow and minor unevenness on the chute surface as they slide down. These disturbances cause lighter goods to frequently collide with the side walls of the chute. Once contacted, their limited weight and insufficient downward momentum prevent them from overcoming friction with the side walls, potentially causing them to stop inside the chute. Even if they continue sliding, they may deviate from their intended path and become stuck at the chute exit, unable to exit smoothly.

[0053] The problem of goods stopping or failing to slide out smoothly in the chute not only significantly reduces the efficiency of goods transportation but also increases the frequency and cost of manual intervention. Workers need to constantly inspect and clean the chute to ensure normal goods transport, which undoubtedly increases manpower and operating costs. Furthermore, frequent goods blockages can trigger a series of chain reactions, such as conveyor belt overload and equipment damage, further affecting the stability and reliability of the entire production or logistics system.

[0054] Meanwhile, traditional chute designs typically use a single structure and material, making it difficult to meet the sorting needs of different types of goods. For example, when goods with different weights, shapes, and surface characteristics move in the chute, their movement speed and kinetic energy consumption vary significantly, which can easily lead to collisions, accumulation, or even damage at the sorting location, affecting sorting efficiency, safety, and stability.

[0055] This utility model proposes a material chute 1, which can improve the stability of chute sorting.

[0056] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the material chute 1 includes a chute body 10, having a chute inlet 11, a chute outlet 12, and a chute track 13 connecting the chute inlet 11 and the chute outlet 12; the chute body 10 includes a sliding wall 10a and two side walls 10b connected to both sides of the sliding wall 10a, the sliding wall 10a and the two side walls 10b forming the chute track 13;

[0057] The slide 13 has a sliding area 131, a first buffer zone 132 and a second buffer zone 133 located on the sliding wall 10a. The first buffer zone 132 and the second buffer zone 133 are located on opposite sides of the sliding area 131. The first buffer zone 132 and the second buffer zone 133 extend obliquely toward the side wall 10b relative to the sliding area 131.

[0058] Specifically, the main body of this logistics sorting chute is the chute body 10, which has a chute inlet 11, a chute outlet 12, and a chute 13 connecting the two. The chute body 10 is composed of a sliding wall 10a and side walls 10b located on both sides of the sliding wall 10a. The chute 13 is formed by the sliding wall 10a and the two side walls 10b. The chute 13 has a sliding area 131 located on the sliding wall 10a, a first buffer zone 132, and a second buffer zone 133. These two buffer zones are distributed on opposite sides of the sliding area 131 and both extend inclined towards the side walls 10b.

[0059] The chute body 10 can be elongated or curved to meet different needs and adapt to the sliding trajectory of goods. As for the material of the chute body 10, wear-resistant and high-strength engineering plastics, such as polycarbonate (PC), can be used, which has good impact resistance and wear resistance, effectively extending the service life of the chute; stainless steel can also be used, ensuring strength while facilitating cleaning and maintenance. No specific limitations are imposed on either material.

[0060] The sliding wall 10a serves as the load-bearing surface of the slide 13, providing a base plane for the goods to slide down. It should be noted that, vertically, the height of the slide inlet 11 side is higher than the height of the slide outlet 12 side to ensure that the goods can slide within the slide 13 under the influence of gravity. The two side walls 10b limit the lateral movement range of the goods and are tightly connected to the sliding wall 10a. They can be manufactured using a one-piece molding process to ensure structural stability. The design of the first buffer zone 132 and the second buffer zone 133, extending at an angle towards the side walls 10b relative to the sliding area 131, provides buffer space for the goods when they deviate from the sliding area 131, preventing direct impact with the side walls 10b.

[0061] The design of the first buffer zone 132 and the second buffer zone 133 effectively reduces the occurrence of goods stopping or deviating from their trajectory due to collisions with the sidewall 10b within the chute. Furthermore, the first buffer zone 132 and the second buffer zone 133 provide cushioning and guidance for the goods, ensuring they can smoothly slide from the chute inlet 11 to the outlet. The first buffer zone 132 and the second buffer zone 133 also dissipate the movement speed and kinetic energy of goods of different weights and shapes, ensuring that the goods move at a relatively consistent speed when they finally enter the sorting position, achieving safe and efficient sorting and improving the efficiency and stability of logistics sorting.

[0062] For example, in a large e-commerce warehouse, packages vary in size and weight. When a package enters the chute from the conveyor belt 2, if it deviates in the sliding area 131, the first buffer zone 132 and the second buffer zone 133 can guide the package back to the normal path. For example, a heavy appliance package may deviate to one side due to inertia when entering the chute. The inclined first buffer zone 132 and the second buffer zone 133 can cushion and guide it, allowing it to slide smoothly and avoiding collision with the side wall 10b, which could damage the package or block the chute.

[0063] The technical solution of this utility model includes a chute body 10 comprising a sliding wall 10a and two side walls 10b connected to both sides of the sliding wall 10a. The sliding wall 10a forms a chute 13. The chute 13 has a sliding area 131, a first buffer zone 132, and a second buffer zone 133. The first buffer zone 132 and the second buffer zone 133 are located on opposite sides of the sliding area 131, and extend inclinedly towards the side walls 10b relative to the sliding area 131. Thus, the first buffer zone 132 and the second buffer zone 133 provide buffering and guiding for the goods, ensuring that the goods can smoothly slide from the chute inlet 11 to the outlet. Simultaneously, they dissipate the movement speed and kinetic energy of goods of different weights and shapes, ensuring that the goods move at essentially the same speed when entering the sorting position, achieving a safe and effective sorting effect and improving the efficiency and stability of logistics sorting.

[0064] Please see Figure 2 , Figure 5 to Figure 7 In one embodiment, the first buffer 132 includes a first sub-buffer 132a and a second sub-buffer 132b connected to each other, with the first sub-buffer 132a located between the sliding area 131 and the second sub-buffer 132b.

[0065] Specifically, the first buffer zone 132 consists of a first sub-buffer zone 132a and a second sub-buffer zone 132b connected together, with the first sub-buffer zone 132a located between the sliding zone 131 and the second sub-buffer zone 132b. In terms of shape, the first sub-buffer zone 132a can have a relatively gentle curve, while the second sub-buffer zone 132b has a curve with a greater curvature. In terms of material, different surface-treated materials can be selected according to different friction coefficient requirements. For example, the surface of the first sub-buffer zone 132a can be smoothed to reduce the friction coefficient, while texture can be added to the surface of the second sub-buffer zone 132b to increase the friction coefficient. Alternatively, the surface of the second sub-buffer zone 132b can be smoothed to reduce the friction coefficient, while texture can be added to the surface of the first sub-buffer zone 132a to increase the friction coefficient; no specific limitations are imposed on these methods.

[0066] Furthermore, the curvature of the second sub-buffer zone 132b is greater than that of the first sub-buffer zone 132a. The first sub-buffer zone 132a and the second sub-buffer zone 132b are connected sequentially to buffer and guide the cargo. The different curvature designs provide differentiated buffering effects for cargo with different speeds and energies. Specifically, for cargo with higher speed and energy, the greater curvature of the second sub-buffer zone 132b can provide a stronger buffering effect, effectively adjusting the speed and direction of movement of the cargo; while the first sub-buffer zone 132a first provides initial buffering for the cargo, ensuring that the cargo smoothly enters the second sub-buffer zone 132b.

[0067] For example, in a courier sorting center, large and heavy packages slide down the chute at a relatively high speed. When these packages enter the first buffer zone 132, the first sub-buffer zone 132a initially slows them down, and then the second sub-buffer zone 132b, with its greater curvature, further buffers and guides the packages, allowing them to slide down smoothly and preventing them from rushing out of the chute or damaging other goods due to excessive speed.

[0068] Please see Figure 6 In one embodiment, the width of the second sub-buffer zone 132b is set to gradually increase and then gradually decrease along the sliding direction of the slide 13.

[0069] Specifically, along the sliding direction of the slide 13, the width of the second sub-buffer zone 132b is set to gradually increase and then gradually decrease. It should be noted that the sliding direction of the slide 13 mentioned here and thereafter refers to the overall extension direction of the slide 13 from the chute inlet 11 to the chute outlet 12, not the specific direction in which the goods slide within the chute. Similarly, the width refers to the width of this area along the sliding direction of the slide 13. In this embodiment, the width of the second sub-buffer zone 132b refers to the width of the second sub-buffer zone 132b along the sliding direction of the slide 13. In shape, it resembles a spindle shape, wider in the middle and narrower at both ends. The material is consistent with the overall shape of the second sub-buffer zone 132b. This shape variation allows sufficient space for buffering and orientation adjustment when goods enter the second sub-buffer zone 132b; upon exiting, it allows them to gradually return to a suitable trajectory, ensuring the stability of the goods' movement. This effectively enhances the buffering and guiding capabilities of the second sub-buffer zone 132b, making the movement of goods within the buffer zone smoother and reducing deviations or jamming caused by improper buffering.

[0070] For example, in a furniture manufacturing plant, large furniture parts have high inertia due to their large size and weight during the conveyor belt process. The special shape of the second sub-buffer zone 132b allows the furniture parts to be adequately buffered when entering and smoothly return to their normal sliding trajectory when leaving, avoiding collisions between the furniture parts and the side wall 10b of the conveyor belt or other components.

[0071] Please continue reading. Figure 6 In one embodiment, the second sub-buffer zone 132b includes a first initial zone 132b1, a first cargo sliding zone 132b2, and a first extension zone 132b3, which are arranged sequentially along the sliding direction of the slide 13.

[0072] Specifically, the second sub-buffer zone 132b includes a first initial area 132b1, a first cargo sliding area 132b2, and a first extension area 132b3 arranged sequentially along the sliding direction of the slide rail 13. In terms of shape, the first cargo sliding area 132b2 is a relatively wide rectangle or trapezoid, while the first initial area 132b1 and the first extension area 132b3 are relatively narrow. Regarding materials, the surface roughness can be adjusted according to the functional requirements of different areas. For example, the first cargo sliding area 132b2 can be made of a smooth material to facilitate rapid cargo entry; the first initial area 132b1 and the first extension area 132b3 can have increased friction to better guide the cargo. This design with varying widths facilitates smooth cargo entry into the second sub-buffer zone 132b, while also enabling precise guidance during cargo entry and exit, optimizing the movement of the cargo within the second sub-buffer zone 132b.

[0073] Furthermore, the width of the first cargo sliding area 132b2 can be configured to be greater than the width of the first initial area 132b1 and the first extension area 132b3. It should be noted that the width of the first cargo sliding area 132b2, the width of the first initial area 132b1, and the width of the first extension area 132b3 refer to the width of this area along the sliding direction of the slide rail 13. The width of the first cargo sliding area 132b2 being greater than the width of the first initial area 132b1 and the first extension area 132b3 means that the maximum width of the first cargo sliding area 132b2 is greater than the maximum width of the first initial area 132b1 and the first extension area 132b3.

[0074] Furthermore, the wider first cargo sliding zone 132b2 reduces the risk of collision when cargo enters the buffer zone, while the narrower first initial zone 132b1 and first extension zone 132b3 help to precisely control the direction of cargo movement, ensuring that the movement of cargo in the buffer zone is more stable and orderly.

[0075] For example, in a book distribution center, when books are conveyed on a chute, a wider first cargo entry area 132b2 allows books to easily enter the buffer zone, preventing the edges of the books from colliding with the edges of the buffer zone; a narrower first initial area 132b1 and a narrower first extension area 132b3 prevent books from shifting excessively in the buffer zone, ensuring that the books slide down neatly, which facilitates subsequent sorting and arrangement.

[0076] Please see Figure 7 In one embodiment, the second buffer 133 includes a third sub-buffer 133a and a fourth sub-buffer 133b connected to each other, with the third sub-buffer 133a located between the sliding area 131 and the fourth sub-buffer 133b.

[0077] Specifically, the second buffer zone 133 consists of two connected sub-buffer zones 133a and 133b, with the third sub-buffer zone 133a located between the sliding zone 131 and the fourth sub-buffer zone 133b. In terms of shape, the third sub-buffer zone 133a is a relatively gentle curve, while the fourth sub-buffer zone 133b is a curve with a greater curvature. Regarding the material, similar to the first buffer zone 132, it can be selected according to the required coefficient of friction. For example, the third sub-buffer zone 133a can be made of a relatively smooth material, while the fourth sub-buffer zone 133b can be made of a material that increases friction; or, the fourth sub-buffer zone 133b can be made of a relatively smooth material, while the third sub-buffer zone 133a can be made of a material that increases friction. No specific limitations are imposed on this.

[0078] Furthermore, the curvature of the fourth sub-buffer zone 133b is greater than that of the third sub-buffer zone 133a. This configuration allows the greater curvature of the fourth sub-buffer zone 133b to provide stronger cushioning for high-energy cargo. Working in conjunction with the third sub-buffer zone 133a, it ensures that the cargo is adequately cushioned and guided within the second buffer zone 133, preventing problems caused by excessive speed or deviations in the cargo's trajectory. Through the cooperation of the third sub-buffer zone 133a and the fourth sub-buffer zone 133b, the cargo is further cushioned and guided, enhancing the second buffer zone 133's ability to adjust the cargo's trajectory.

[0079] For example, in an automotive parts manufacturing plant, heavier metal parts have significant kinetic energy during the conveying process via a chute. The third sub-buffer zone 133a provides initial buffering for the parts, and then the fourth sub-buffer zone 133b, with its greater curvature, further decelerates and adjusts the direction, ensuring that the parts pass safely and smoothly through the second buffer zone 133, preventing collision damage.

[0080] Please continue reading. Figure 7 In one embodiment, the width of the fourth sub-buffer zone 133b is set to gradually increase and then gradually decrease along the sliding direction of the slide 13.

[0081] Specifically, along the sliding direction of the slide 13, the width of the fourth sub-buffer zone 133b is set to gradually increase and then gradually decrease. Its shape is similar to the second sub-buffer zone 132b, being a spindle shape that is wider in the middle and narrower at both ends. The material is consistent with that of the fourth sub-buffer zone 133b. This shape variation provides ample buffering and adjustment space for the goods, allowing them to enter the subsequent area at a suitable speed and direction when leaving the fourth sub-buffer zone 133b. This effectively enhances the buffering and guiding effect of the fourth sub-buffer zone 133b on the goods, making the movement of the goods in the second buffer zone 133 smoother and reducing the possibility of excessive speed or directional deviation when leaving the fourth sub-buffer zone 133b.

[0082] For example, in a logistics warehouse, when parts of large equipment are conveyed on a chute, this setting of the fourth sub-buffer zone 133b allows the parts to gradually adjust their speed and direction during the buffering process, so that they can accurately fall into the designated position when leaving, thus improving the accuracy and efficiency of logistics operations.

[0083] Please continue reading. Figure 7 In one embodiment, the fourth sub-buffer zone 133b includes a second initial zone 133b1, a second cargo sliding zone 133b2, and a second extension zone 133b3, which are arranged sequentially along the sliding direction of the slide 13.

[0084] Specifically, the fourth sub-buffer zone 133b includes a second initial zone 133b1, a second cargo sliding zone 133b2, and a second extension zone 133b3 arranged sequentially along the sliding direction of the slide rail 13. In terms of shape, the second cargo sliding zone 133b2 is a wider area, while the second initial zone 133b1 and the second extension zone 133b3 are relatively narrower. Regarding materials, the surface properties can be adjusted according to the functional requirements of different areas; for example, the second cargo sliding zone 133b2 can be made of a smooth material, while the second initial zone 133b1 and the second extension zone 133b3 can be made of a material that increases friction.

[0085] In one embodiment, the width of the second cargo sliding area 133b2 is greater than the width of the second initial area 133b1 and the second extension area 133b3, and the width of the second cargo sliding area 133b2 is greater than the width of the third sub-buffer zone 133a. It should be noted that the aforementioned width refers to the width of this area along the sliding direction of the slide rail 13. The fact that the width of the second cargo sliding area 133b2 is greater than the width of the second initial area 133b1 and the second extension area 133b3 means that the maximum width of the second cargo sliding area 133b2 is greater than the maximum width of the second initial area 133b1 and the second extension area 133b3. Similarly, the fact that the width of the second cargo sliding area 133b2 is greater than the width of the third sub-buffer zone 133a means that the maximum width of the second cargo sliding area 133b2 is greater than the maximum width of the third sub-buffer zone 133a.

[0086] The wider second cargo entry zone 133b2 reduces the risk of collision when cargo enters the fourth sub-buffer zone 133b, while the narrower second initial zone 133b1 and second extension zone 133b3 help to precisely control the direction of cargo movement, ensuring more stable and orderly movement of cargo in the second buffer zone 133. This width design facilitates cargo entry into the fourth sub-buffer zone 133b, while enabling precise guidance during cargo entry and exit, optimizing the overall movement of cargo in the second buffer zone 133.

[0087] For example, in a lighting production workshop, when fragile lighting fixtures are conveyed in a chute, a wider second cargo entry zone 133b2 can prevent the lighting fixtures from colliding and ensure that the lighting fixtures safely enter the buffer zone; a narrower second initial zone 133b1 and a second extension zone 133b3 can prevent the lighting fixtures from shifting excessively in the buffer zone, allowing the lighting fixtures to slide out of the buffer zone smoothly and reducing the probability of damage to the lighting fixtures.

[0088] In one embodiment, the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is not less than the coefficient of friction of the sliding zone 131. Specifically, the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is greater than or equal to the coefficient of friction of the sliding zone 131. In terms of material selection, the sliding zone 131 can be made of smooth metal or plastic to ensure that the goods can slide down quickly in the sliding zone 131; the first buffer zone 132 and the second buffer zone 133 can be made of materials that increase friction, such as rubber coating materials with special textures.

[0089] When the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is greater than the coefficient of friction of the sliding zone 131, this difference in coefficient of friction allows the goods to decelerate rapidly and adjust their direction of movement when entering the buffer zone, preventing them from becoming uncontrollable due to excessive speed. Simultaneously, it enhances the chute's control over the movement of goods, ensuring effective buffering and guidance within the buffer zone and reducing the risk of goods colliding with the side wall 10b or rushing out of the chute due to excessive speed. When the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is equal to the coefficient of friction of the sliding zone 131, it facilitates the manufacturing of the material chute 1.

[0090] For example, during the parcel sorting process, parcels sliding down at high speed can quickly slow down upon entering a buffer zone due to their higher coefficient of friction, allowing them to slide smoothly and preventing damage from collisions. Similarly, during peak delivery periods like "Double 11," a large number of parcels are rapidly transported in chutes; the buffer zone's higher coefficient of friction effectively controls parcel speed, ensuring smooth sorting operations.

[0091] In one embodiment, the coefficient of friction of the first sub-buffer zone 132a is not greater than the coefficient of friction of the second sub-buffer zone 132b.

[0092] Specifically, the coefficient of friction of the first sub-buffer zone 132a is less than or equal to the coefficient of friction of the second sub-buffer zone 132b. In terms of material selection, the first sub-buffer zone 132a can use a low-friction material, such as a polytetrafluoroethylene (PTFE) coating, to allow goods to enter the buffer zone quickly; the second sub-buffer zone 132b uses a high-friction material, such as a textured rubber material, to enhance the deceleration and guiding effect on the goods. The lower coefficient of friction in the first sub-buffer zone 132a facilitates rapid entry of goods into the buffer zone, reducing jamming during entry; the higher coefficient of friction in the second sub-buffer zone 132b effectively reduces the speed of the goods, adjusts their trajectory, and allows them to pass smoothly through the buffer zone. By setting different coefficients of friction, adjustments can be made to the movement of the goods at different stages, enabling precise control of the goods' speed and trajectory. Of course, the coefficient of friction of the first sub-buffer zone 132a can also be set to be equal to that of the second sub-buffer zone 132b. In this case, the first and second sub-buffer zones 132a can be made of the same material with the same coefficient of friction.

[0093] For example, in an electronics manufacturing workshop, when small electronic components are conveyed in a chute, the low coefficient of friction of the first sub-buffer zone 132a ensures that the electronic components enter the buffer zone quickly and avoids the components from stalling; the high coefficient of friction of the second sub-buffer zone 132b enables the electronic components to decelerate smoothly and prevents the components from being damaged or deviating from the track due to excessive speed.

[0094] In one embodiment, the coefficient of friction of the third sub-buffer zone 133a is not greater than the coefficient of friction of the fourth sub-buffer zone 133b. Specifically, the coefficient of friction of the third sub-buffer zone 133a is less than or equal to the coefficient of friction of the fourth sub-buffer zone 133b. Regarding material selection, the third sub-buffer zone 133a can be made of a low-friction material, such as a smooth-surfaced metal material, to facilitate the rapid entry of goods; the fourth sub-buffer zone 133b can be made of a high-friction material, such as a plastic material with anti-slip texture, to achieve deceleration and guidance of goods. Alternatively, the third sub-buffer zone 133a can be made of a high-friction material, and the fourth sub-buffer zone 133b can be made of a low-friction material; no specific limitation is made in this regard.

[0095] For example, the lower coefficient of friction in the third sub-buffer zone 133a facilitates the rapid entry of goods into the fourth sub-buffer zone 133b, reducing congestion during entry. Conversely, the higher coefficient of friction in the fourth sub-buffer zone 133b effectively reduces the speed of the goods, adjusting their trajectory and allowing them to pass smoothly through the second buffer zone 133. Setting different coefficients of friction allows for adjustments to the movement of goods at different stages within the second buffer zone 133, enabling precise control over the speed and trajectory of the goods. Alternatively, the coefficients of friction in the third and fourth sub-buffer zones 133a can be configured to be the same, facilitating uniform deceleration control of the goods and improving the production of the material chute 1.

[0096] For example, in a precision instrument manufacturing workshop, when tiny and expensive precision instruments are conveyed in a chute, the low coefficient of friction of the third sub-buffer zone 133a ensures that the instruments quickly enter the fourth sub-buffer zone 133b, avoiding instrument stagnation; the high coefficient of friction of the fourth sub-buffer zone 133b enables the instruments to decelerate smoothly, preventing the instruments from being damaged or deviating from the track due to excessive speed.

[0097] It is worth mentioning that you should refer to Figure 6 to Figure 8 The slide 13 has a sliding area 131, a first buffer zone 132, and a second buffer zone 133 located on the sliding wall 10a. The first buffer zone 132 includes a first sub-buffer zone 132a and a second sub-buffer zone 132b connected to each other. The second buffer zone 133 includes a third sub-buffer zone 133a and a fourth sub-buffer zone 133b connected to each other. The second sub-buffer zone 132b includes a first initial area 132b1, a first cargo sliding in area 132b2, and a first extension area 132b3. The fourth sub-buffer zone 133b includes a second initial area 133b1, a second cargo sliding in area 133b2, and a second extension area 133b3.

[0098] In the second sub-buffer zone 132b, the friction coefficients of the first initial zone 132b1, the first cargo sliding zone 132b2, and the first extension zone 132b3 can be set to be different in order to specifically consume kinetic energy and guide the cargo. Similarly, the friction coefficients of the second initial zone 133b1, the second cargo sliding zone 133b2, and the second extension zone 133b3 of the fourth sub-buffer zone 133b can also be set to have different friction coefficients.

[0099] In addition, it should be noted that the sliding area 131, the first sub-buffer zone 132a in the first buffer zone 132, and the third sub-buffer zone 133a in the second buffer zone 133 can also be further divided into multiple small areas along the sliding direction of the slide rail 13, and the friction coefficient of multiple small areas can be further adjusted according to the actual use scenario to adapt to different needs.

[0100] Please see Figure 6 and Figure 7 In one embodiment, the connection between the first buffer zone 132 and the second buffer zone 133 and the sliding zone 131 is smoothly transitioned. Specifically, the connection between the first buffer zone 132 and the second buffer zone 133 and the sliding zone 131 adopts a smooth transition design. The connection can be designed with rounded corners or arcs to avoid sharp edges. This smooth transition allows goods to pass smoothly from the sliding zone 131 into the buffer zone or from the buffer zone back to the sliding zone 131, reducing jamming and impact caused by unevenness at the connection. This effectively reduces the resistance of the goods during movement, preventing the goods from changing their motion state due to collisions with the connection between the first buffer zone 132, the second buffer zone 133, and the sliding zone 131, further improving the smoothness of the goods sliding within the chute and reducing the risk of the goods stopping or being damaged.

[0101] For example, in the material conveying chutes of a food processing workshop, the food items being conveyed are mostly fragile, such as pastries. When the pastries enter the buffer zone from the sliding area 131, the smooth transition at the connection point can prevent the pastries from breaking due to collision, ensuring the integrity of the product and reducing losses.

[0102] Please see Figure 6 and Figure 7 In one embodiment, the cross-sections of the first buffer zone 132 and the second buffer zone 133 are curved in the sliding direction perpendicular to the slide rail 13.

[0103] Specifically, in the sliding direction perpendicular to the slide rail 13, the cross-sections of the first buffer zone 132 and the second buffer zone 133 are curved. This curved shape can be arc-shaped, elliptical, etc., and its design purpose is to better conform to the movement trajectory of the goods. The material used is also the same wear-resistant material as the slide rail body 10.

[0104] The curved surface design allows for a larger contact area and more uniform pressure distribution when the cargo comes into contact with the first buffer zone 132 or the second buffer zone 133, thereby reducing the possibility of excessive local stress on the cargo. This enhances the cushioning effect of the first buffer zone 132 and the second buffer zone 133 on the cargo, effectively dispersing the pressure between the cargo and the first buffer zone 132 and the second buffer zone 133, reducing the possibility of cargo damage, and improving the stability of the cargo during movement in the first buffer zone 132 and the second buffer zone 133.

[0105] For example, during the logistics and transportation of glass products, the surface of the glass is fragile and easily breaks due to impact. Using a buffer zone with a curved cross-section allows the pressure to be evenly distributed when the glass product comes into contact with the buffer zone, greatly reducing the risk of breakage and ensuring product quality.

[0106] Please see Figure 2 and Figure 3In one embodiment, the slide 13 is curved and has an inner curved side W1 and an outer curved side W2. A first buffer zone 132 is provided on the inner curved side W1 and a second buffer zone 133 is provided on the outer curved side W2.

[0107] Specifically, the slide 13 is curved, having an inner curved side W1 and an outer curved side W2. A first buffer zone 132 is located on the inner curved side W1, and a second buffer zone 133 is located on the outer curved side W2. The curved shape of the slide 13 can be designed with different radii of curvature according to the actual site and cargo movement requirements. In terms of materials, the slide 13 can be made of high-strength metal materials, such as aluminum alloy, to ensure structural strength.

[0108] Furthermore, along the sliding direction of the slide rail 13, the width of the second buffer zone 133 is greater than the width of the first buffer zone 132. The position and width design of the first and second buffer zones 132 are to accommodate the movement characteristics of goods on the curved slide rail 13. The wider second buffer zone 133 provides greater buffer space for goods moving on the outer curved side W2 of the slide rail, preventing goods from being thrown out of the slide rail 13 due to centrifugal force; the first buffer zone 132 plays an auxiliary guiding role for goods on the inner curved side W1 of the slide rail. This configuration effectively solves the problem of unstable movement of goods on the curved slide rail 13 caused by centrifugal force and other factors, improving the safety and stability of goods transmission on the curved slide rail 13.

[0109] For example, in the process of transporting parts in amusement park facilities, the chutes are usually designed to be curved due to space constraints. In this case, the wider second buffer zone 133 located on the outer curved side W2 of the chutes can prevent parts from being thrown off the chutes 13 due to centrifugal force, while the first buffer zone 132 located on the inner curved side helps guide the parts and ensures that the parts are transported smoothly on the curved chutes 13.

[0110] Furthermore, the first buffer zone 132 spans the inner curved side W1 of the slide, and the inner curved side W1 forms an angle α. The second buffer zone 133 intersects the angle bisector of the angle α. Specifically, along the extension direction of the slide 13, i.e. the sliding direction of the goods, the first buffer zone 132 spans the entire inner curved side W1 of the slide to provide better guidance for the goods. The slide (13) is curved, and the inner curved side W1 of the slide forms an angle α. This angle α refers to the angle formed between the upstream and downstream of the inner curved side W1 of the slide, i.e., between the two side walls 10b of the slide body 10. If the two side walls 10b of the slide body 10 are irregular side walls 10b, then the line connecting the two end points of the side wall 10b of the inner curved side W1 of the slide body 10, and the connection point between the bends of the side walls 10b, is taken as the two sides of the angle α.

[0111] The second buffer zone 133 intersects the angle bisector of the included angle α, as shown below. Figure 3 As shown, the angle bisector of the included angle α is M. It should be noted that the angle bisector of the included angle α is a virtual line, which changes accordingly based on the size of the included angle α. In this way, on the one hand, the position of the second buffer zone 133 is defined, and on the other hand, goods that still have a large amount of energy after sliding out of the first buffer zone 132 can continue to slide into the second buffer zone 133 to continue to consume energy. This ensures that the goods move at a basically consistent speed when they finally enter the sorting position, achieving a safe and efficient sorting effect and improving the efficiency and stability of logistics sorting.

[0112] Please see Figure 1 to Figure 3 In one embodiment, the width of the chute inlet 11 is greater than the width of the chute outlet 12; and / or

[0113] The width of the sliding area 131 at the inlet is greater than the width of the sliding area 131 at the outlet; and / or

[0114] Along the sliding direction of the slide 13, the width of the sliding area 131 is set to gradually decrease.

[0115] Specifically, there are three width variations: the width of the chute inlet 11 is greater than the width of the chute outlet 12; the width of the sliding area 131 at the inlet is greater than the width at the outlet; and the width of the sliding area 131 gradually decreases along the sliding direction of the chute 13. The overall shape of the chute resembles a trapezoid that is wider at the top and narrower at the bottom. In terms of material, the chute body 10 can be made of sturdy plastic or metal.

[0116] These width variations help guide the goods to gradually accelerate down the chute while limiting their lateral movement, allowing them to move more concentratedly towards the chute outlet 12. This improves the efficiency of goods transport, reduces lateral offset within the chute, and prevents goods from colliding with the sidewall 10b or clogging the chute due to excessive offset.

[0117] For example, in a grain processing workshop, the gradually decreasing width of the chute allows the grain to automatically gather as it slides down, facilitating subsequent collection and processing. Similarly, in the conveying process of rice after hulling, this chute design allows the rice to enter the next processing stage more concentratedly, improving production efficiency.

[0118] Please see Figure 1 to Figure 3In one embodiment, the first buffer zone 132 is positioned closer to the chute inlet 11 than the second buffer zone 133. Specifically, objects entering the chute often possess a certain velocity and kinetic energy, generating significant impact force. Positioning the first buffer zone 132 near the chute inlet 11 allows for immediate buffering of objects entering the chute, reducing the impact on the chute and subsequent structures, lowering the risk of wear and damage due to impact, and extending the service life of the chute and related equipment.

[0119] For example, in a logistics sorting system, packages enter the chute from the conveyor line at a relatively high speed. The first buffer zone can effectively slow down the packages, preventing damage caused by high-speed impacts on the chute, and also preventing the chute from deforming or cracking due to prolonged exposure to large impacts. Furthermore, this arrangement allows for a more rational layout of the entire chute system and more efficient use of space. By placing the first buffer zone 132 close to the chute inlet 11, the subsequent second buffer zone 133 and other functional areas can be arranged more flexibly according to actual needs, achieving more functions or accommodating more objects for buffering and processing within a limited space.

[0120] Please see Figure 6 and Figure 7 In one embodiment, in the vertical direction, the height of the inlet side of the chute body 10 is higher than the height of the outlet side of the chute body 10.

[0121] Specifically, in the vertical direction, the height of the inlet side of the chute body 10 is higher than the height of the outlet side. The chute as a whole has a certain inclination angle, the size of which can be adjusted according to the characteristics of the goods and the conveying requirements, generally between 15° and 45°. The material is the same as that of the chute body 10.

[0122] This height difference utilizes gravity to provide the downward momentum for the goods, ensuring that they can smoothly slide from the chute inlet 11 to the outlet. No additional power unit is required; the goods can be transported solely by gravity, reducing equipment costs and energy consumption, while ensuring the goods continue to slide down the chute, minimizing the possibility of goods stopping inside.

[0123] For example, in building material warehouses, the design of a high inlet and low outlet for conveying heavier bricks via chutes fully utilizes gravity, allowing the bricks to slide down quickly without additional power, thus improving handling efficiency. Similarly, on small construction sites, workers use these chutes to quickly transport bricks to the work floors, saving manpower and time.

[0124] In one embodiment, the slide 13 is provided with a guide protrusion structure (not shown in the figure); or

[0125] The sliding area 131, the first buffer zone 132, and the second buffer zone 133 are each provided with different types of guide protrusion structures (not shown in the figure).

[0126] Specifically, the slide 13 is provided with guide protrusions; or the sliding area 131, the first buffer zone 132, and the second buffer zone 133 are each provided with different types of guide protrusions. The shape of the guide protrusions can be strip-shaped, dot-shaped, or serrated, etc. In terms of material, the same material as the slide body 10 can be selected, and it can be set in the corresponding area by integral molding or post-attachment.

[0127] The guide protrusion structure further guides the movement of goods, preventing them from deviating or spinning within the chute. Different types of guide protrusion structures are installed in different areas, allowing for targeted guidance based on the movement status of the goods in different zones. This improves the accuracy and stability of the goods' movement within the chute, ensuring that the goods slide down the predetermined path and reducing blockages and damage caused by deviations from the trajectory.

[0128] For example, in an electronic chip manufacturing workshop, when tiny chips are conveyed in a chute, guide protrusions can precisely guide the movement of the chips, preventing damage due to positional deviations.

[0129] Please see Figure 1 to Figure 3 In another embodiment of the present invention, the material chute 1 includes a chute body 10, having a chute inlet 11, a chute outlet 12, and a chute track 13 connecting the chute inlet 11 and the chute outlet 12. The chute inlet 11 is flared. The chute body 10 includes a sliding wall 10a and two side walls 10b connected to both sides of the sliding wall 10a. The sliding wall 10a and the two side walls 10b form the chute track 13.

[0130] The slide 13 has a sliding area 131, a first buffer zone 132 and a second buffer zone 133 located on the sliding wall 10a. The first buffer zone 132 and the second buffer zone 133 are located on opposite sides of the sliding area 131. The first buffer zone 132 and the second buffer zone 133 extend obliquely toward the side wall 10b relative to the sliding area 131. The friction coefficient of the first buffer zone 132 and the second buffer zone 133 is not less than the friction coefficient of the sliding area 131.

[0131] Specifically, the main body of this logistics sorting chute is the chute body 10, which has a chute inlet 11, a chute outlet 12, and a chute 13 connecting the two. The chute body 10 is composed of a sliding wall 10a and side walls 10b located on both sides of the sliding wall 10a, and the chute 13 is formed by the sliding wall 10a. The chute 13 has a sliding area 131, a first buffer zone 132, and a second buffer zone 133. These two buffer zones are distributed on opposite sides of the sliding area 131 and both extend inclinedly towards the side walls 10b.

[0132] The chute body 10 can be elongated or curved to meet different needs and adapt to the sliding trajectory of goods. As for the material of the chute body 10, wear-resistant and high-strength engineering plastics, such as polycarbonate (PC), can be used, which has good impact resistance and wear resistance, effectively extending the service life of the chute; stainless steel can also be used, ensuring strength while facilitating cleaning and maintenance. No specific limitations are imposed on either material.

[0133] The sliding wall 10a serves as the bearing surface of the slide 13, providing a base plane for the goods to slide down. It should be noted that, vertically, the height of the slide inlet 11 side is higher than the height of the slide outlet 12 side to ensure that the goods can slide within the slide 13 under the influence of gravity. The two side walls 10b limit the lateral movement range of the goods and are tightly connected to the sliding wall 10a. They can be manufactured using a one-piece molding process to ensure structural stability. The design of the first buffer zone 132 and the second buffer zone 133, extending at an angle towards the side walls 10b relative to the sliding area 131, provides a buffer space for the goods when they deviate from the sliding area 131, preventing direct impact with the side walls 10b.

[0134] The design of the first buffer zone 132 and the second buffer zone 133 effectively reduces the occurrence of goods stopping or deviating from their trajectory due to collisions with the sidewall 10b within the chute. Furthermore, the first buffer zone 132 and the second buffer zone 133 provide cushioning and guidance for the goods, ensuring they can smoothly slide from the chute inlet 11 to the outlet. The first buffer zone 132 and the second buffer zone 133 also dissipate the movement speed and kinetic energy of goods of different weights and shapes, ensuring that the goods move at a relatively consistent speed when they finally enter the sorting position, achieving safe and efficient sorting and improving the efficiency and stability of logistics sorting.

[0135] For example, in a large e-commerce warehouse, packages vary in size and weight. When a package enters the chute from the conveyor belt 2, if it deviates in the sliding area 131, the first buffer zone 132 and the second buffer zone 133 can guide the package back to the normal path. For example, a heavy appliance package may deviate to one side due to inertia when entering the chute. The inclined first buffer zone 132 and the second buffer zone 133 can cushion and guide it, allowing it to slide smoothly and avoiding collision with the side wall 10b, which could damage the package or block the chute.

[0136] The friction coefficients of the first buffer zone 132 and the second buffer zone 133 are greater than those of the sliding zone 131. In terms of material selection, the sliding zone 131 can be made of smooth metal or plastic to ensure that goods can slide down quickly within the sliding zone 131; the first buffer zone 132 and the second buffer zone 133 are made of materials that increase friction, such as rubber-coated materials with special textures.

[0137] When the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is greater than the coefficient of friction of the sliding zone 131, this difference in coefficient of friction allows the goods to decelerate rapidly and adjust their direction of movement when entering the buffer zone, preventing them from becoming uncontrollable due to excessive speed. Simultaneously, it enhances the chute's control over the movement of goods, ensuring effective buffering and guidance within the buffer zone and reducing the risk of goods colliding with the side wall 10b or rushing out of the chute due to excessive speed. When the coefficient of friction of the first buffer zone 132 and the second buffer zone 133 is equal to the coefficient of friction of the sliding zone 131, it facilitates the manufacturing of the material chute 1.

[0138] For example, during the parcel sorting process, parcels sliding down at high speed can quickly slow down upon entering a buffer zone due to their higher coefficient of friction, allowing them to slide smoothly and preventing damage from collisions. Similarly, during peak delivery periods like "Double 11," a large number of parcels are rapidly transported in chutes; the buffer zone's higher coefficient of friction effectively controls parcel speed, ensuring smooth sorting operations.

[0139] Please see Figure 5 to Figure 7 In one embodiment, the first buffer 132 includes a first sub-buffer 132a and a second sub-buffer 132b connected to each other, with the first sub-buffer 132a located between the sliding area 131 and the second sub-buffer 132b.

[0140] Specifically, the first buffer zone 132 consists of a first sub-buffer zone 132a and a second sub-buffer zone 132b connected together, with the first sub-buffer zone 132a located between the sliding zone 131 and the second sub-buffer zone 132b. In terms of shape, the first sub-buffer zone 132a can have a relatively gentle curve, while the second sub-buffer zone 132b has a curve with a greater curvature. In terms of material, different surface-treated materials can be selected according to different friction coefficient requirements. For example, the surface of the first sub-buffer zone 132a can be smoothed to reduce the friction coefficient, while texture can be added to the surface of the second sub-buffer zone 132b to increase the friction coefficient. Alternatively, the surface of the second sub-buffer zone 132b can be smoothed to reduce the friction coefficient, while texture can be added to the surface of the first sub-buffer zone 132a to increase the friction coefficient; no specific limitations are imposed on these methods.

[0141] Furthermore, the curvature of the second sub-buffer zone 132b is greater than that of the first sub-buffer zone 132a. The first sub-buffer zone 132a and the second sub-buffer zone 132b are connected sequentially to buffer and guide the cargo. The different curvature designs provide differentiated buffering effects for cargo with different speeds and energies. Specifically, for cargo with higher speed and energy, the greater curvature of the second sub-buffer zone 132b can provide a stronger buffering effect, effectively adjusting the speed and direction of movement of the cargo; while the first sub-buffer zone 132a first provides initial buffering for the cargo, ensuring that the cargo smoothly enters the second sub-buffer zone 132b.

[0142] For example, in a courier sorting center, large and heavy packages slide down the chute at a relatively high speed. When these packages enter the first buffer zone 132, the first sub-buffer zone 132a initially slows them down, and then the second sub-buffer zone 132b, with its greater curvature, further buffers and guides the packages, allowing them to slide down smoothly and preventing them from rushing out of the chute or damaging other goods due to excessive speed.

[0143] Please see Figure 5 to Figure 7 In one embodiment, the second buffer 133 includes a third sub-buffer 133a and a fourth sub-buffer 133b connected to each other, with the third sub-buffer 133a located between the sliding area 131 and the fourth sub-buffer 133b.

[0144] Specifically, the second buffer zone 133 consists of two connected sub-buffer zones 133a and 133b, with the third sub-buffer zone 133a located between the sliding zone 131 and the fourth sub-buffer zone 133b. In terms of shape, the third sub-buffer zone 133a is a relatively gentle curve, while the fourth sub-buffer zone 133b is a curve with a greater curvature. Regarding the material, similar to the first buffer zone 132, it can be selected according to the required coefficient of friction. For example, the third sub-buffer zone 133a can be made of a relatively smooth material, while the fourth sub-buffer zone 133b can be made of a material that increases friction; or, the fourth sub-buffer zone 133b can be made of a relatively smooth material, while the third sub-buffer zone 133a can be made of a material that increases friction. No specific limitations are imposed on this.

[0145] Furthermore, the curvature of the fourth sub-buffer zone 133b is greater than that of the third sub-buffer zone 133a. This configuration allows the greater curvature of the fourth sub-buffer zone 133b to provide stronger cushioning for high-energy cargo. Working in conjunction with the third sub-buffer zone 133a, it ensures that the cargo is adequately cushioned and guided within the second buffer zone 133, preventing problems caused by excessive speed or deviations in the cargo's trajectory. Through the cooperation of the third sub-buffer zone 133a and the fourth sub-buffer zone 133b, the cargo is further cushioned and guided, enhancing the second buffer zone 133's ability to adjust the cargo's trajectory.

[0146] For example, in an automotive parts manufacturing plant, heavier metal parts have significant kinetic energy during the conveying process via a chute. The third sub-buffer zone 133a provides initial buffering for the parts, and then the fourth sub-buffer zone 133b, with its greater curvature, further decelerates and adjusts the direction, ensuring that the parts pass safely and smoothly through the second buffer zone 133, preventing collision damage.

[0147] In one embodiment, the coefficient of friction of the first sub-buffer zone 132a is not greater than the coefficient of friction of the second sub-buffer zone 132b; and / or,

[0148] The friction coefficient of the third sub-buffer zone 133a is not greater than the friction coefficient of the fourth sub-buffer zone 133b.

[0149] Specifically, the coefficient of friction of the first sub-buffer zone 132a is less than or equal to the coefficient of friction of the second sub-buffer zone 132b. In terms of material selection, the first sub-buffer zone 132a can use a low-friction material, such as a polytetrafluoroethylene (PTFE) coating, to allow goods to enter the buffer zone quickly; the second sub-buffer zone 132b uses a high-friction material, such as a textured rubber material, to enhance the deceleration and guiding effect on the goods. The lower coefficient of friction in the first sub-buffer zone 132a facilitates rapid entry of goods into the buffer zone, reducing jamming during entry; the higher coefficient of friction in the second sub-buffer zone 132b effectively reduces the speed of the goods, adjusts their trajectory, and allows them to pass smoothly through the buffer zone. By setting different coefficients of friction, adjustments can be made to the movement of the goods at different stages, enabling precise control of the goods' speed and trajectory. Of course, the coefficient of friction of the first sub-buffer zone 132a can also be set to be equal to that of the second sub-buffer zone 132b. In this case, the first and second sub-buffer zones 132a can be made of the same material with the same coefficient of friction.

[0150] For example, in an electronics manufacturing workshop, when small electronic components are conveyed in a chute, the low coefficient of friction of the first sub-buffer zone 132a ensures that the electronic components enter the buffer zone quickly and avoids the components from stalling; the high coefficient of friction of the second sub-buffer zone 132b enables the electronic components to decelerate smoothly and prevents the components from being damaged or deviating from the track due to excessive speed.

[0151] Similarly, specifically, the coefficient of friction of the third sub-buffer zone 133a is less than or equal to the coefficient of friction of the fourth sub-buffer zone 133b. Regarding material selection, the third sub-buffer zone 133a can be made of a low-friction material, such as a smooth-surfaced metal, to facilitate the rapid entry of goods; the fourth sub-buffer zone 133b can be made of a high-friction material, such as a plastic material with anti-slip texture, to decelerate and guide the goods. Alternatively, the third sub-buffer zone 133a can be made of a high-friction material, and the fourth sub-buffer zone 133b can be made of a low-friction material; no specific limitation is made in this regard.

[0152] For example, the lower coefficient of friction in the third sub-buffer zone 133a facilitates the rapid entry of goods into the fourth sub-buffer zone 133b, reducing congestion during entry. Conversely, the higher coefficient of friction in the fourth sub-buffer zone 133b effectively reduces the speed of the goods, adjusting their trajectory and allowing them to pass smoothly through the second buffer zone 133. Setting different coefficients of friction allows for adjustments to the movement of goods at different stages within the second buffer zone 133, enabling precise control over the speed and trajectory of the goods. Alternatively, the coefficients of friction in the third and fourth sub-buffer zones 133a can be configured to be the same, facilitating uniform deceleration control of the goods and improving the production of the material chute 1.

[0153] For example, in a precision instrument manufacturing workshop, when tiny and expensive precision instruments are conveyed in a chute, the low coefficient of friction of the third sub-buffer zone 133a ensures that the instruments quickly enter the fourth sub-buffer zone 133b, avoiding instrument stagnation; the high coefficient of friction of the fourth sub-buffer zone 133b enables the instruments to decelerate smoothly, preventing the instruments from being damaged or deviating from the track due to excessive speed.

[0154] Please see Figure 5 to Figure 7 In one embodiment, the second sub-buffer zone 132b includes a first initial zone 132b1, a first cargo sliding zone 132b2, and a first extension zone 132b3, which are arranged sequentially along the sliding direction of the slide rail 13; the coefficient of friction of the first cargo sliding zone 132b2 is not less than the coefficients of friction of the first initial zone 132b1 and the first extension zone 132b3; and / or,

[0155] The fourth sub-buffer zone 133b includes a second initial zone 133b1, a second cargo sliding zone 133b2, and a second extension zone 133b3. The second initial zone 133b1, the second cargo sliding zone 133b2, and the second extension zone 133b3 are arranged sequentially along the sliding direction of the slide rail 13. The friction coefficient of the second cargo sliding zone 133b2 is not less than the friction coefficients of the second initial zone 133b1 and the second extension zone 133b3.

[0156] Specifically, the second sub-buffer zone 132b includes a first initial area 132b1, a first cargo sliding area 132b2, and a first extension area 132b3 arranged sequentially along the sliding direction of the slide rail 13. The width of the first cargo sliding area 132b2 can be set to be greater than that of the first initial area 132b1 and the first extension area 132b3. In terms of shape, the first cargo sliding area 132b2 is a relatively wide rectangle or trapezoid, while the first initial area 132b1 and the first extension area 132b3 are relatively narrow. Regarding materials, the surface roughness can be adjusted according to the functional requirements of different areas. For example, the first cargo sliding area 132b2 can be made of a smooth material to facilitate rapid cargo entry; the first initial area 132b1 and the first extension area 132b3 can have increased friction to better guide the cargo. This design with varying widths facilitates smooth cargo entry into the second sub-buffer zone 132b, while also enabling precise guidance during cargo entry and exit, optimizing the movement of the cargo within the second sub-buffer zone 132b. The friction coefficient of the first cargo sliding in zone 132b2 is not less than the friction coefficient of the first initial zone 132b1 and the first extension zone 132b3. It can be configured such that the friction coefficient of the first cargo sliding in zone 132b2 is greater than or equal to the friction coefficient of the first initial zone 132b1 and the first extension zone 132b3.

[0157] Furthermore, the wider first cargo sliding zone 132b2 reduces the risk of collision when cargo enters the buffer zone, while the narrower first initial zone 132b1 and first extension zone 132b3 help to precisely control the direction of cargo movement, ensuring that the movement of cargo in the buffer zone is more stable and orderly.

[0158] For example, in a book distribution center, when books are conveyed on a chute, a wider first cargo entry area 132b2 allows books to easily enter the buffer zone, preventing the edges of the books from colliding with the edges of the buffer zone; a narrower first initial area 132b1 and a narrower first extension area 132b3 prevent books from shifting excessively in the buffer zone, ensuring that the books slide down neatly, which facilitates subsequent sorting and arrangement.

[0159] Furthermore, the coefficient of friction of the first cargo sliding zone 132b2 is greater than or equal to the coefficients of friction of the first initial zone 132b1 and the first extension zone 132b3. Regarding material selection, the first initial zone 132b1 and the first extension zone 132b3 can use low-friction materials with different coefficients of friction, such as polytetrafluoroethylene (PTFE) coatings, to allow the cargo to enter quickly; while the first cargo sliding zone 132b2 uses high-friction materials, such as rubber with a special texture, to enhance the deceleration and guiding effect on the cargo. By setting different coefficients of friction, adjustments can be made to the movement state of the cargo at different stages, enabling precise control of the cargo's speed and trajectory.

[0160] Please see Figure 5The fourth sub-buffer zone 133b includes a second initial zone 133b1, a second cargo sliding zone 133b2, and a second extension zone 133b3 arranged sequentially along the sliding direction of the slide rail 13. The width of the second cargo sliding zone 133b2 is greater than that of the second initial zone 133b1 and the second extension zone 133b3, and also greater than that of the third sub-buffer zone 133a. In terms of shape, the second cargo sliding zone 133b2 is a wider area, while the second initial zone 133b1 and the second extension zone 133b3 are relatively narrower. Regarding materials, the surface properties can be adjusted according to the functional requirements of different areas; for example, the second cargo sliding zone 133b2 can be made of a smooth material, while the second initial zone 133b1 and the second extension zone 133b3 can be made of a material that increases friction.

[0161] The wider second cargo sliding zone 133b2 reduces the risk of collision when cargo enters the fourth sub-buffer zone 133b, while the narrower second initial zone 133b1 and second extension zone 133b3 help to precisely control the direction of cargo movement, ensuring more stable and orderly movement of cargo in the second buffer zone 133. This width design facilitates cargo entry into the fourth sub-buffer zone 133b and enables precise guidance during cargo entry and exit, optimizing the overall movement of cargo in the second buffer zone 133. The coefficient of friction of the second cargo sliding zone 133b2 is not less than the coefficients of friction of the second initial zone 133b1 and the second extension zone 133b3, and can be configured such that the coefficient of friction of the second cargo sliding zone 133b2 is greater than or equal to the coefficients of friction of the second initial zone 133b1 and the second extension zone 133b3.

[0162] For example, in a lighting production workshop, when fragile lighting fixtures are conveyed in a chute, a wider second cargo entry zone 133b2 can prevent the lighting fixtures from colliding and ensure that the lighting fixtures safely enter the buffer zone; a narrower second initial zone 133b1 and a second extension zone 133b3 can prevent the lighting fixtures from shifting excessively in the buffer zone, allowing the lighting fixtures to slide out of the buffer zone smoothly and reducing the probability of damage to the lighting fixtures.

[0163] Furthermore, the coefficients of friction of the second initial zone 133b1, the second cargo sliding zone 133b2, and the second extension zone 133b3 are different. Similarly, in terms of material selection, the second initial zone 133b1 and the second extension zone 133b3 can use low-friction materials with different coefficients of friction, such as polytetrafluoroethylene coating materials, to allow the cargo to enter quickly; while the second cargo sliding zone 133b2 uses high-friction materials, such as rubber materials with special textures, to enhance the deceleration and guiding effect on the cargo. By setting different coefficients of friction, adjustments can be made to the movement state of the cargo at different stages, enabling precise control of the cargo's speed and trajectory.

[0164] Please see Figure 1 and Figure 8In this application, the logistics sorting chute is typically used in conjunction with the conveyor belt 2, with the chute inlet 11 of the chute body 10 abutting against the side of the conveyor belt 2. When goods need to be separated from the conveyor belt 2 and entered into the logistics sorting chute for sorting, the goods can be divided into heavy goods, medium-weight goods, and light-weight goods according to their weight.

[0165] Please see Figure 1 In the diagram, X refers to the direction of movement of conveyor belt 2, and Y refers to the direction of movement of goods when they are subjected to force and enter the material chute 1.

[0166] Please see Figure 8 In the diagram, S1 represents the sliding path of a heavy cargo. Due to its large weight, the heavy cargo has significant initial kinetic energy when entering the sliding zone 131 from the conveyor belt 2. Upon entering the sliding zone 131, the gravitational potential energy Ep = mgh (where m is the mass of the cargo, g is the gravitational acceleration, and h is the height difference) is relatively high, causing a rapid increase in speed during the sliding process. When approaching the first buffer zone 132, due to its high speed and large kinetic energy, it is easy to deviate from the sliding zone 131 and enter the first buffer zone 132. In the first buffer zone 132, it first passes through the first sub-buffer zone 132a. The friction coefficient of the first sub-buffer zone 132a is relatively small, resulting in a weak deceleration effect on the cargo, allowing it to pass quickly. Upon reaching the second sub-buffer zone 132b, due to its larger curvature and higher friction coefficient, according to the friction work formula W = Fs = mgμs (where μ is the sliding friction coefficient and s is the sliding distance), the cargo experiences significant resistance, its speed decreases rapidly, and its direction of motion is adjusted. After leaving the first buffer zone 132, if the speed is still high, it may rush towards the second buffer zone 133. In the second buffer zone 133, the goods first pass through the third sub-buffer zone 133a for initial buffering, and then enter the fourth sub-buffer zone 133b. The fourth sub-buffer zone 133b has a larger curvature and a higher coefficient of friction, further decelerating and adjusting the trajectory of the goods to reduce their speed to a suitable range, and finally allowing them to smoothly slide out of the chute from the sliding zone 131 to reach their destination. Alternatively, in the second buffer zone 133, the goods may only pass through the third buffer zone, where they are further decelerated and their trajectory adjusted to reduce their speed to a suitable range, and finally slide out of the chute from the sliding zone 131 to reach their destination.

[0167] Please see Figure 8In the diagram, S2 represents the sliding path of medium-weight cargo. After entering the sliding zone 131 of the chute, the gravitational potential energy of the medium-weight cargo is converted into kinetic energy, and its speed gradually increases. While moving within the sliding zone 131, its speed is relatively lower than that of heavy-weight cargo. Upon entering the first buffer zone 132, it undergoes initial deceleration in the first sub-buffer zone 132a, followed by further adjustment of its speed and direction in the second sub-buffer zone 132b. Because the kinetic energy of medium-weight cargo is less than that of heavy-weight cargo, its speed is effectively controlled after passing through the first buffer zone 132, and it generally will not rush into the second buffer zone 133, but will instead slide directly out of the chute from the sliding zone 131 at a suitable speed. If it does rush into the second buffer zone 133, it will enter the third sub-buffer zone 133a for further buffering, further decelerating the cargo and adjusting its trajectory to reduce its speed to a suitable range, ultimately allowing it to smoothly slide out of the chute from the sliding zone 131 and reach its destination. Throughout this process, the relationship between gravitational potential energy, kinetic energy, and the work done by friction still follows the aforementioned formula, adjusting the cargo's energy and trajectory through changes in the friction coefficient in different areas.

[0168] Please see Figure 8 In the diagram, S3 represents the sliding path of a low-weight cargo. After entering the sliding zone 131 of the chute, the cargo has relatively low gravitational potential energy and is mainly affected by friction. Because friction does work and consumes energy, its speed increases slowly. The cargo moves in a basically parabolic trajectory within the sliding zone 131. Due to its light weight, it is relatively susceptible to external interference, but because of its slow speed, it generally does not deviate from the sliding zone 131 and enter the buffer zone. Finally, it slides out of the chute from the exit of the sliding zone 131 at a relatively stable, low speed to reach its destination. Throughout the process, the changes in the kinetic energy, gravitational potential energy, and work done by friction of the cargo are relatively gradual. According to the formula, its energy change mainly manifests in the work done to overcome friction, maintaining a relatively stable motion until it slides out of the chute.
