[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] In modern logistics, warehousing and various manufacturing scenarios, efficient and stable transportation of goods is the key link to ensure the smooth progress of the entire process. The conveyor belt-chute combination is widely used in the process of transferring goods from one location to another due to its relatively simple structure and low cost.

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

[0051] When the goods on the conveyor belt are transferred to the chute, the weight of the goods has a great adverse effect on the transmission process. For heavier goods, during the sliding process in the chute, due to their own large gravity, the inertia and impact force generated are also relatively large. This causes the heavy objects to touch the left and right side walls of the chute in turn when sliding down. During the contact process, large friction and collision forces will be generated with the side walls. This friction and collision force may cause uncontrollable changes in the movement state of the heavy objects, greatly increasing the risk of the heavy objects stopping in the chute. Even if the heavy objects have not completely stopped, they may deviate from the normal sliding trajectory due to multiple collisions and frictions with the side walls, resulting in the inability to slide out of the chute exit smoothly, which will cause cargo blockage and seriously affect the working efficiency of the entire conveying system.

[0052] Lighter cargoes face similar difficulties. Although they have less gravity, they are easily disturbed by factors such as airflow and slight unevenness on the surface of the chute when sliding down the chute. Under the influence of these interference factors, lighter cargoes will frequently touch the left and right side walls of the chute. Once they touch the side walls, due to their light weight, the sliding power generated is limited and they cannot overcome the friction between the side walls, so they are very likely to stop in the chute. Even if they can continue to slide down, they may get stuck at the exit of the chute because they deviate from the normal trajectory and cannot slide out smoothly.

[0053] The problem of goods stopping in the chute or failing to slide out smoothly will not only greatly reduce the efficiency of goods delivery, but also increase the frequency and cost of manual intervention. The staff needs to constantly check and clean the chute to ensure that the goods can be delivered normally, which undoubtedly increases the manpower burden and operating costs. In addition, frequent cargo blockages may also cause 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] At the same time, traditional chute designs usually use a single structure and material, which is difficult to meet the needs of sorting different types of goods. For example, when goods of different weights, shapes and surface characteristics move in the chute, their movement speed and kinetic energy consumption vary greatly, which can easily cause collisions, accumulation and even damage at the sorting location, affecting sorting efficiency, safety and stability.

[0055] The present invention provides a material chute 1, which can improve the stability of chute sorting.

[0056] See also 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 slide 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, and the sliding wall 10a and the two side walls 10b form the slide 13;

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

[0058] Specifically, the main body of the logistics sorting chute is a chute body 10, which is provided with 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 and the two side walls 10b. The chute 13 has a sliding area 131 located on the sliding wall 10a, a first buffer area 132 and a second buffer area 133, which are distributed on opposite sides of the sliding area 131 and both extend obliquely toward the side wall 10b.

[0059] The chute body 10 can be arranged in a long strip shape, or the chute body 10 can be arranged in a curved shape to meet different needs and adapt to the sliding trajectory of the goods. As for the material of the chute body 10, wear-resistant and high-strength engineering plastics such as polycarbonate (PC) can be selected, which has good impact resistance and wear resistance and can effectively extend the service life of the chute; stainless steel can also be used to ensure strength while being easy to clean and maintain, and there is no specific limitation on this.

[0060] The sliding wall 10a serves as the bearing surface of the slide 13, providing a basic plane for the goods to slide down. It should be noted that in the vertical direction, 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 in the slide 13 under the action of gravity. The two side walls 10b are used to limit the lateral movement range of the goods, and are tightly connected to the sliding wall 10a. They can be manufactured using an integrated molding process to ensure a stable structure. The design of the first buffer zone 132 and the second buffer zone 133 extending obliquely toward the side wall 10b relative to the sliding zone 131 allows the goods to have a buffer space when they deviate from the sliding zone 131 to avoid direct impact on the side wall 10b.

[0061] The design of the first buffer zone 132 and the second buffer zone 133 can effectively reduce the situation where the goods stop or deviate from the track due to collision with the side wall 10b in the chute. In addition, the first buffer zone 132 and the second buffer zone 133 are provided to provide a buffer and guide function for the goods, ensuring that the goods can slide smoothly from the chute entrance 11 to the exit, and the first buffer zone 132 and the second buffer zone 133 consume the movement speed and kinetic energy of goods of different weights and shapes, so that the movement speed of the goods is basically the same when they finally enter the sorting position, achieving a safe and effective sorting effect, and improving the efficiency and stability of logistics sorting.

[0062] For example, in a large e-commerce warehouse, various packages have different sizes and weights. When a package enters the chute from the conveyor belt 2, if the package deviates in the sliding area 131, the first buffer 132 and the second buffer 133 can guide the package back to the normal path. For example, a heavy electrical appliance package deviates to one side due to inertia when entering the chute. The inclined first buffer 132 and the second buffer 133 can buffer and guide it, so that it slides down smoothly, avoiding collision with the side wall 10b, causing damage to the package or blocking the chute.

[0063] According to the technical solution of the present invention, the chute body 10 includes a sliding wall 10a and two side walls 10b connected to the two sides of the sliding wall 10a, and the sliding wall 10a is formed with a slide 13; wherein the slide 13 has a sliding area 131, a first buffer area 132 and a second buffer area 133, the first buffer area 132 and the second buffer area 133 are located on opposite sides of the sliding area 131, and the first buffer area 132 and the second buffer area 133 extend obliquely toward the side wall 10b relative to the sliding area 131. In this way, by setting the first buffer area 132 and the second buffer area 133, a buffering and guiding effect is provided for the goods, ensuring that the goods can slide smoothly from the chute entrance 11 to the exit, and at the same time, the movement speed and kinetic energy of goods of different weights and shapes are consumed, so that when the goods finally enter the sorting position, the movement speed is basically the same, achieving a safe and effective sorting effect, and improving the efficiency and stability of logistics sorting.

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

[0065] Specifically, the first buffer zone 132 is composed of a first sub-buffer zone 132a and a second sub-buffer zone 132b connected to each other, and the first sub-buffer zone 132a is located between the sliding zone 131 and the second sub-buffer zone 132b. In terms of shape, the first sub-buffer zone 132a may be a relatively gentle curve, and the second sub-buffer zone 132b may be a curve with a greater curvature. In terms of material, materials with different surface treatments may be selected according to different friction coefficient requirements, such as smoothing the surface of the first sub-buffer zone 132a to reduce the friction coefficient; adding textures to the surface of the second sub-buffer zone 132b to increase the friction coefficient, or smoothing the surface of the second sub-buffer zone 132b to reduce the friction coefficient; adding textures to the surface of the first sub-buffer zone 132a to increase the friction coefficient, and there is no specific limitation on this.

[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 in sequence to jointly buffer and guide the goods. Different curvature designs provide differentiated buffering effects for goods with different speeds and energies. Among them, for goods with faster speeds and greater energy, the larger curvature of the second sub-buffer zone 132b can provide a stronger buffering effect, so that the speed and movement direction of the goods can be effectively adjusted; while the first sub-buffer zone 132a first performs preliminary buffering on the goods to ensure that the goods enter the second sub-buffer zone 132b smoothly.

[0067] For example, in an express delivery sorting center, large and heavy parcels slide down the chute at a faster speed. When these parcels enter the first buffer zone 132, the first sub-buffer zone 132a initially decelerates them, and then the second sub-buffer zone 132b further buffers and guides the parcels with a greater curvature, so that they slide down smoothly, thereby preventing the parcels from rushing out of the chute or damaging other goods due to excessive speed.

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

[0069] Specifically, along the sliding direction of the slide 13, the width of the second sub-buffer 132b is set in a trend of gradually increasing and then gradually decreasing. It should be noted that the sliding direction of the slide 13 described here and in the following text refers to an extension direction of the slide 13 from the chute entrance 11 to the chute exit 12 as a whole, not the specific direction of the goods sliding in the chute. Similarly, the width refers to the width of the area along the sliding direction of the slide 13. The width of the second sub-buffer 132b in this embodiment refers to the width of the second sub-buffer 132b along the sliding direction of the slide 13. In shape, it is similar to a shuttle shape with a wide middle and narrow ends. The material is consistent with the second sub-buffer 132b as a whole. This shape change allows the goods to have enough space for buffering and adjusting direction when entering the second sub-buffer 132b; when leaving, it can gradually return to the appropriate motion trajectory to ensure the stability of the movement of the goods. The second sub-buffer 132b effectively enhances the buffering and guiding ability of the goods, making the movement of the goods in the buffer more stable, and reducing the deviation or jamming of the goods due to improper buffering.

[0070] For example, in a furniture manufacturing factory, when large furniture parts are being transported in the chute, they have large inertia due to their large size and heavy weight. The special shape of the second sub-buffer zone 132b can fully buffer the furniture parts when they enter, and smoothly return to the normal sliding trajectory when they leave, thereby preventing the furniture parts from colliding with the chute sidewall 10b or other parts.

[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-in zone 132b2 and a first extension zone 132b3, and the first initial zone 132b1, the first cargo sliding-in zone 132b2 and the first extension zone 132b3 are arranged in sequence along the sliding direction of the slide 13.

[0072] Specifically, the second sub-buffer zone 132b includes a first initial zone 132b1, a first cargo sliding-in zone 132b2, and a first extension zone 132b3, which are arranged in sequence along the sliding direction of the slideway 13. In terms of shape, the first cargo sliding-in zone 132b2 is a wider rectangle or trapezoid, and the first initial zone 132b1 and the first extension zone 132b3 are relatively narrow. In terms of material, the surface roughness can be adjusted according to the functional requirements of different areas. For example, the first cargo sliding-in zone 132b2 can be made of smooth material to facilitate the rapid entry of cargo; the first initial zone 132b1 and the first extension zone 132b3 can appropriately increase friction to better guide the cargo. This width variation design facilitates the cargo to enter the second sub-buffer zone 132b smoothly, and at the same time achieves precise guidance when the cargo enters and leaves, optimizing the movement process of the cargo in the second sub-buffer zone 132b.

[0073] Further, the width of the first cargo sliding-in area 132b2 can be configured to be greater than the widths of the first initial area 132b1 and the first extension area 132b3. It should be noted that the width of the first cargo sliding-in area 132b2 and the widths of the first initial area 132b1 and the first extension area 132b3 refer to the width of the area along the sliding direction of the slideway 13. The width of the first cargo sliding-in area 132b2 is greater than the widths of the first initial area 132b1 and the first extension area 132b3. It means that the maximum width of the first cargo sliding-in 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-in area 132b2 reduces the risk of collision when cargo enters the buffer zone, while the narrower first initial area 132b1 and the first extension area 132b3 help to precisely control the movement direction of cargo, 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 in the chute, the wider first cargo sliding area 132b2 allows the books to easily enter the buffer zone, preventing the edge of the book from colliding with the edge of the buffer zone; the narrower first initial area 132b1 and the first extension area 132b3 can prevent the books from excessively deflecting in the buffer zone, ensuring that the books slide down neatly, facilitating subsequent sorting and sorting.

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

[0077] Specifically, the second buffer zone 133 is composed of a third sub-buffer zone 133a and a fourth sub-buffer zone 133b connected to each other, and the third sub-buffer zone 133a is 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, and the fourth sub-buffer zone 133b is a curve with a greater curvature. In terms of material, similar to the first buffer zone 132, it can be selected according to the friction coefficient requirements, such as the third sub-buffer zone 133a uses a relatively smooth material, and the fourth sub-buffer zone 133b uses a material that increases friction, or the fourth sub-buffer zone 133b uses a relatively smooth material, and the third sub-buffer zone 133a uses a material that increases friction, and there is no specific limitation on this.

[0078] Furthermore, the curvature of the fourth sub-buffer zone 133b is greater than the curvature of the third sub-buffer zone 133a. With such a configuration, for goods with greater energy, the greater curvature of the fourth sub-buffer zone 133b can provide a stronger buffering effect, and work in conjunction with the third sub-buffer zone 133a to ensure that the goods are adequately buffered and guided in the second buffer zone 133, thereby avoiding problems with the goods due to excessive speed or deviation in the movement trajectory. The third sub-buffer zone 133a and the fourth sub-buffer zone 133b cooperate with each other to further buffer and guide the goods, thereby enhancing the ability of the second buffer zone 133 to adjust the movement trajectory of the goods.

[0079] For example, in an automobile parts manufacturing plant, heavier metal parts have greater kinetic energy during the chute transmission process. The third sub-buffer zone 133a first performs preliminary buffering on the parts, and then the fourth sub-buffer zone 133b further decelerates and adjusts the direction with a greater curvature to ensure that the parts pass through the second buffer zone 133 safely and smoothly, preventing the parts from being damaged by collision.

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

[0081] Specifically, along the sliding direction of the slideway 13, the width of the fourth sub-buffer zone 133b is set to gradually increase and then gradually decrease. The shape is similar to the second sub-buffer zone 132b, which is a shuttle shape with a wide middle and narrow ends. The material is consistent with the fourth sub-buffer zone 133b as a whole. This shape change provides sufficient buffer space and adjustment space for the goods, so that the goods can enter the subsequent area at a suitable speed and direction when leaving the fourth sub-buffer zone 133b. The buffering and guiding effect of the fourth sub-buffer zone 133b on the goods is effectively enhanced, so that the movement of the goods in the second buffer zone 133 is smoother, and the situation of excessive speed or direction deviation of the goods when leaving the fourth sub-buffer zone 133b is reduced.

[0082] For example, in a logistics warehouse, when parts of large equipment are conveyed in a chute, the setting of the fourth sub-buffer 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, thereby 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, and the second initial zone 133b1, the second cargo sliding zone 133b2 and the second extension zone 133b3 are arranged in sequence 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, which are arranged in sequence along the sliding direction of the slideway 13. In terms of shape, the second cargo sliding zone 133b2 is a wider area, and the second initial zone 133b1 and the second extension zone 133b3 are relatively narrow. In terms of material, the surface characteristics can be adjusted according to the functional requirements of different areas, such as the second cargo sliding zone 133b2 uses a smooth material, and the second initial zone 133b1 and the second extension zone 133b3 use a material that increases friction.

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

[0086] The wider second cargo sliding-in area 133b2 reduces the risk of collision when cargo enters the fourth sub-buffer zone 133b, while the narrower second initial area 133b1 and second extension area 133b3 help to accurately control the movement direction of cargo, ensuring that cargo moves more stably and orderly in the second buffer zone 133. This width design facilitates cargo to enter the fourth sub-buffer zone 133b, while achieving precise guidance when cargo enters and leaves, optimizing the overall movement process of cargo in the second buffer zone 133.

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

[0088] In one embodiment, 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 zone 131. Specifically, the friction coefficient of the first buffer zone 132 and the second buffer zone 133 is greater than or equal to the friction coefficient of the sliding zone 131. In terms of material selection, the sliding zone 131 can be made of smooth metal or plastic material 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 friction coefficient of the first buffer zone 132 and the second buffer zone 133 is greater than the friction coefficient of the sliding zone 131, the difference in friction coefficients allows the goods to quickly decelerate and adjust the direction of movement when entering the buffer zone, preventing the goods from losing control due to excessive speed. At the same time, the control ability of the chute over the movement of goods is enhanced, ensuring that the goods are effectively buffered and guided in the buffer zone, reducing the risk of the goods colliding with the side wall 10b or rushing out of the chute due to excessive speed. When the friction coefficient of the first buffer zone 132 and the second buffer zone 133 is equal to the friction coefficient of the sliding zone 131, the production and manufacturing of the material chute 1 is convenient.

[0090] For example, during the express parcel sorting process, when the parcels slide down at high speed and enter the buffer zone, the larger friction coefficient can quickly reduce the parcel speed, allowing it to slide down smoothly and avoid collision and damage. For example, during express peak periods such as "Double 11", a large number of parcels are quickly transported in the chute. The larger friction coefficient of the buffer zone can effectively control the parcel speed and ensure the smooth progress of the sorting work.

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

[0092] Specifically, the friction coefficient of the first sub-buffer zone 132a is less than or equal to the friction coefficient of the second sub-buffer zone 132b. In terms of material selection, the first sub-buffer zone 132a can use materials with low friction coefficients, such as polytetrafluoroethylene coating materials, so that the goods can quickly enter the buffer zone; the second sub-buffer zone 132b uses materials with high friction coefficients, such as rubber materials with special textures, to enhance the deceleration and guidance of the goods. Among them, the smaller friction coefficient of the first sub-buffer zone 132a facilitates the rapid entry of the goods into the buffer zone and reduces the jamming of the goods when entering; the larger friction coefficient of the second sub-buffer zone 132b can effectively reduce the speed of the goods, adjust the movement trajectory of the goods, and allow the goods to pass through the buffer zone smoothly. By setting different friction coefficients, the movement state of the goods at different stages can be adjusted to achieve precise control of the movement speed and trajectory of the goods. Of course, the friction coefficient of the first sub-buffer zone 132a can be set to be equal to the friction coefficient of the second sub-buffer zone 132b. At this time, the first sub-buffer zone 132a and the second sub-buffer zone 132b can be set with the same friction coefficient material.

[0093] For example, in an electronic product manufacturing workshop, when small electronic components are conveyed in a slide, the low friction coefficient of the first sub-buffer zone 132a can ensure that the electronic components quickly enter the buffer zone to avoid stagnation of the components; the high friction coefficient of the second sub-buffer zone 132b can decelerate the electronic components smoothly to prevent the components from being damaged or deviating from the trajectory due to excessive speed.

[0094] In one embodiment, the friction coefficient of the third sub-buffer zone 133a is not greater than the friction coefficient of the fourth sub-buffer zone 133b. Specifically, the friction coefficient of the third sub-buffer zone 133a is less than or equal to the friction coefficient of the fourth sub-buffer zone 133b. In terms of material selection, the third sub-buffer zone 133a may use a material with a low friction coefficient, such as a metal material with a smooth surface, to facilitate the rapid entry of goods; the fourth sub-buffer zone 133b may use a material with a high friction coefficient, such as a plastic material with an anti-slip texture, to achieve deceleration and guidance of the goods, or the third sub-buffer zone 133a may use a material with a high friction coefficient, and the fourth sub-buffer zone 133b may use a material with a low friction coefficient, and there is no specific limitation on this.

[0095] For example, the smaller friction coefficient of the third sub-buffer 133a facilitates the rapid entry of the goods into the fourth sub-buffer 133b, reducing the jamming of the goods when entering; the larger friction coefficient of the fourth sub-buffer 133b can effectively reduce the speed of the goods, adjust the movement trajectory of the goods, and allow the goods to pass smoothly through the second buffer 133. The setting of different friction coefficients can be adjusted according to the movement state of the goods at different stages of the second buffer 133, so as to achieve fine control of the movement speed and trajectory of the goods. Of course, the friction coefficient of the third sub-buffer 133a and the friction coefficient of the fourth sub-buffer 133b can also be configured to be the same, so as to facilitate the uniform deceleration control of the goods and the production of the material chute 1.

[0096] For example, in a precision instrument manufacturing workshop, when tiny and expensive precision instruments are transported in a slide, the low friction coefficient of the third sub-buffer zone 133a can ensure that the instruments quickly enter the fourth sub-buffer zone 133b to avoid stagnation of the instruments; the high friction coefficient of the fourth sub-buffer zone 133b can decelerate the instruments smoothly to prevent the instruments from being damaged or deviating from the trajectory due to excessive speed.

[0097] It is worth mentioning that see Figures 6 to 8 , and the preceding and following contents. The slideway 13 has a sliding area 131, a first buffer area 132 and a second buffer area 133 located on the sliding wall 10a, the first buffer area 132 includes a first sub-buffer area 132a and a second sub-buffer area 132b connected to each other, the second buffer area 133 includes a third sub-buffer area 133a and a fourth sub-buffer area 133b connected to each other, wherein the second sub-buffer area 132b includes a first initial area 132b1, a first cargo sliding-in area 132b2 and a first extension area 132b3, and the fourth sub-buffer area 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 so as to specifically consume the 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 13, and the friction coefficients of the multiple small areas can be further adjusted according to actual usage scenarios to meet different needs.

[0100] See also 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 is designed with a smooth transition. The connection can be designed to be rounded or arc-shaped to avoid sharp corners. This smooth transition allows the goods to pass smoothly when entering the buffer zone from the sliding zone 131 or returning from the buffer zone to the sliding zone 131, reducing the jamming and impact caused by the uneven connection. It effectively reduces the resistance of the goods during movement, avoids the goods from changing the movement state due to collision with the connection between the first buffer zone 132, the second buffer zone 133 and the sliding zone 131, further improves the smoothness of the goods sliding in the chute, and reduces the risk of stopping or damage to the goods.

[0101] For example, in the material conveying chute of a food processing workshop, the conveyed food is mostly fragile, such as cakes. When the cakes enter the buffer zone from the sliding zone 131, the smooth transition connection can prevent the cakes from being broken due to collision, thereby ensuring the integrity of the product and reducing loss.

[0102] See also Figure 6 and Figure 7 In one embodiment, in a sliding direction perpendicular to the slideway 13, the cross-sections of the first buffer zone 132 and the second buffer zone 133 are curved.

[0103] Specifically, in a direction perpendicular to the sliding direction of the slideway 13, the cross-sections of the first buffer zone 132 and the second buffer zone 133 are arranged in a curved surface. The curved surface shape can be an arc, an ellipse, etc., and its design purpose is to better fit the moving track of the goods. The material is also selected to be a wear-resistant material consistent with the slideway body 10.

[0104] The curved surface design makes the contact area larger and the pressure distribution more uniform when the goods come into contact with the first buffer zone 132 or the second buffer zone 133, thereby reducing the situation where the goods are subjected to excessive local force. The first buffer zone 132 and the second buffer zone 133 enhance the buffering effect of the goods, effectively disperse the pressure between the goods and the first buffer zone 132 and the second buffer zone 133, reduce the possibility of damage to the goods, and improve the stability of the goods when they move in the first buffer zone 132 and the second buffer zone 133.

[0105] For example, during the logistics transmission of glass products, the surface of glass products is fragile and easily broken due to collision. The use of a buffer zone with a curved cross-section can evenly disperse the pressure of glass products when they contact the buffer zone, greatly reducing the risk of glass products breaking and ensuring product quality.

[0106] See also Figure 2 and Figure 3In one embodiment, the slide 13 is arranged in a curved shape and has an inner curved side W1 and an outer curved side W2 opposite to each other. The first buffer zone 132 is arranged on the inner curved side W1 and the second buffer zone 133 is arranged on the outer curved side W2.

[0107] Specifically, the slide 13 is arranged in a curved shape, having an inner curved side W1 and an outer curved side W2, a first buffer zone 132 is arranged on the inner curved side W1, and a second buffer zone 133 is arranged on the outer curved side W2. The curved shape of the slide 13 can be designed to have different curvature radii according to the actual site and the requirements of cargo movement. In terms of material, the entire 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 slideway 13, the width of the second buffer zone 133 is greater than the width of the first buffer zone 132. The position and width of the first buffer zone 132 and the second buffer zone 133 are designed to adapt to the movement characteristics of the goods on the curved slideway 13. The wider second buffer zone 133 can provide a larger buffer space for the goods moving on the outer curved side W2 of the slideway to prevent the goods from rushing out of the slideway 13 due to centrifugal force; the first buffer zone 132 plays an auxiliary guiding role for the goods on the inner curved side W1 of the slideway. Such a setting effectively solves the problem of unstable movement of goods on the curved slideway 13 due to factors such as centrifugal force, and improves the safety and stability of the transportation of goods on the curved slideway 13.

[0109] For example, in the process of transferring parts of amusement park facilities, the slide is usually designed to be curved due to space limitations. In this case, the wider second buffer 133 located on the outer curved side W2 of the slide can prevent the parts from being thrown out of the slide 13 due to centrifugal force, and the first buffer 132 located on the inner curved side assists in guiding the parts to ensure that the parts are smoothly transferred on the curved slide 13.

[0110] Furthermore, the first buffer zone 132 spans the inner curved side W1 of the slide, and the inner curved side W1 of the slide forms an angle α, and the second buffer zone 133 intersects with the bisector of the angle α. Specifically, along the extension direction of the slide 13, that is, the sliding direction of the goods, the first buffer zone 132 spans the entire inner curved side W1 of the slide to better guide the goods. The slide (13) is arranged in a curved shape, and the inner curved side W1 of the slide forms an angle α, which refers to the upstream and downstream of the inner curved side W1 of the slide, that is, the angle formed 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, the end points of the two ends of the side wall 10b of the inner curved side W1 of the slide of the slide body 10, and the connecting line between the connection point between the side wall 10b and the bending point of the side wall 10b are taken as the two sides of the angle α.

[0111] The second buffer zone 133 intersects with the angle bisector of the angle α, as shown in FIG. Figure 3 As shown, the bisector of the angle α is M. It should be noted that the bisector of the angle α is a virtual line, which changes accordingly according to the change in the size of the angle α. In this way, on the one hand, the position of the second buffer 133 is limited, and on the other hand, the goods that still have a large amount of energy after sliding out of the first buffer 132 can continue to slide into the second buffer 133 to continue to consume energy, so that when the goods finally enter the sorting position, the movement speed is basically the same, achieving a safe and effective sorting effect, and improving the efficiency and stability of logistics sorting.

[0112] See also Figures 1 to 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 inlet side of the sliding area 131 is greater than the width of the outlet side of the sliding area 131; and / or

[0114] Along the sliding direction of the slideway 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 inlet side is greater than the width of the sliding area 131 outlet side; along the sliding direction of the slide 13, the width of the sliding area 131 is set to gradually decrease. The overall shape of the chute is similar to a trapezoid that is wide at the top and narrow at the bottom. In terms of material, the chute body 10 can be made of solid plastic or metal material.

[0116] These width changes help guide the cargo to gradually accelerate down the chute, while limiting the lateral movement range of the cargo, so that the cargo moves more concentratedly toward the chute outlet 12. This improves the cargo delivery efficiency, reduces the lateral deviation of the cargo in the chute, and prevents the cargo from colliding with the side wall 10b or blocking the chute due to excessive deviation.

[0117] For example, in a grain processing workshop, when grains are conveyed in the chute, the gradually decreasing width design allows the grains to automatically gather during the sliding process, making it easier to collect and process them later. For example, in the process of conveying rice after husking, this chute design allows the rice to enter the next processing link more concentratedly, improving production efficiency.

[0118] See also Figures 1 to 3In one embodiment, the first buffer zone 132 is disposed closer to the chute entrance 11 than the second buffer zone 133. Specifically, when an object enters the chute, it often has a certain speed and kinetic energy, which will generate a large impact force. The first buffer zone 132 is disposed near the chute entrance 11, so that the object entering the chute can be buffered in the first place, the impact of the object on the chute and subsequent structures can be reduced, the risk of wear and damage caused by the impact can be reduced, and the service life of the chute and related equipment can be extended.

[0119] For example, in a logistics sorting system, when a package enters the chute from the conveyor line at a high speed, the first buffer zone can effectively slow down the speed of the package, prevent the package from being damaged by high-speed collision with the chute, and prevent the chute from being deformed or broken due to long-term large impact force. In addition, this setting method can make the layout of the entire chute system more reasonable and make better use of space. By placing the first buffer zone 132 close to the chute entrance 11, the subsequent second buffer zone 133 and other functional areas can be arranged more flexibly according to actual conditions, so as to realize more functions or accommodate more objects for buffering and processing in a limited space.

[0120] See also Figure 6 and Figure 7 In one embodiment, in the vertical direction, the height of the entrance side of the chute body 10 is higher than the height of the exit side of the chute body 10 .

[0121] Specifically, in the vertical direction, the entrance side height of the chute body 10 is higher than the exit side height. The chute as a whole presents a certain inclination angle, which can be adjusted according to the characteristics of the goods and the transmission requirements, generally between 15°-45°. The material is consistent with the chute body 10.

[0122] This height difference uses gravity to provide downward force for the goods, ensuring that the goods can slide smoothly from the chute entrance 11 to the exit. No additional power device is required, and the goods can be transferred by gravity, which reduces equipment costs and energy consumption, while ensuring that the goods continue to slide in the chute and reducing the situation where the goods stop in the chute.

[0123] For example, in a building material warehouse, when heavier bricks are transported in a chute, the design of a high entrance and low exit can make full use of gravity, allowing bricks to slide down quickly without additional power, improving handling efficiency. For example, on a small construction site, workers can quickly transport bricks to the construction floor through this chute, saving manpower and time.

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

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

[0126] Specifically, a guide protrusion structure is provided in the slideway 13; or different types of guide protrusion structures are provided in the sliding area 131, the first buffer area 132 and the second buffer area 133. The guide protrusion structure may be in the shape of a strip, a dot or a serrated shape. In terms of material, the same material as the slideway body 10 may be selected and provided in the corresponding area by integral molding or later gluing.

[0127] The guide protrusion structure can further guide the movement direction of the goods and prevent the goods from deviating or spinning in the chute. Different types of guide protrusion structures are set in different areas, and targeted guidance can be performed according to the movement status of the goods in different areas. The accuracy and stability of the movement of goods in the chute are improved, ensuring that the goods slide along the predetermined path and reducing blockage and damage caused by deviation from the track.

[0128] For example, in an electronic chip manufacturing workshop, when tiny chips are transported in a slide, the guiding protrusion structure can accurately guide the movement of the chips to prevent the chips from being damaged due to position deviation.

[0129] See also Figures 1 to 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 slide 13 connecting the chute inlet 11 and the chute outlet 12, and the chute inlet 11 is expanded; the chute body 10 includes a sliding wall 10a and two side walls 10b connected to both sides of the sliding wall 10a, and the sliding wall 10a and the two side walls 10b form the slide 13;

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

[0131] Specifically, the main body of the logistics sorting chute is a chute body 10, which is provided with 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 area 132 and a second buffer area 133, which are distributed on opposite sides of the sliding area 131 and both extend obliquely toward the side wall 10b.

[0132] The chute body 10 can be arranged in a long strip shape, or the chute body 10 can be arranged in a curved shape to meet different needs and adapt to the sliding trajectory of the goods. As for the material of the chute body 10, wear-resistant and high-strength engineering plastics such as polycarbonate (PC) can be selected, which has good impact resistance and wear resistance and can effectively extend the service life of the chute; stainless steel can also be used to ensure strength while being easy to clean and maintain, and there is no specific limitation on this.

[0133] The sliding wall 10a serves as the bearing surface of the slide 13, providing a basic plane for the goods to slide down. It should be noted that in the vertical direction, the height of the slide entrance 11 side is higher than the height of the slide exit 12 side to ensure that the goods can slide in the slide 13 under the action of gravity. The two side walls 10b are used to limit the lateral movement range of the goods. They are tightly connected to the sliding wall 10a and can be manufactured using an integrated molding process to ensure a stable structure. The first buffer zone 132 and the second buffer zone 133 are designed to extend obliquely toward the side wall 10b relative to the sliding zone 131, so that when the goods deviate from the sliding zone 131, there is a buffer space to avoid direct impact on the side wall 10b.

[0134] The design of the first buffer zone 132 and the second buffer zone 133 can effectively reduce the situation where the goods stop or deviate from the track due to collision with the side wall 10b in the chute. In addition, the first buffer zone 132 and the second buffer zone 133 are provided to provide a buffer and guide function for the goods, ensuring that the goods can slide smoothly from the chute entrance 11 to the exit, and the first buffer zone 132 and the second buffer zone 133 consume the movement speed and kinetic energy of goods of different weights and shapes, so that the movement speed of the goods is basically the same when they finally enter the sorting position, achieving a safe and effective sorting effect, and improving the efficiency and stability of logistics sorting.

[0135] For example, in a large e-commerce warehouse, various packages have different sizes and weights. When a package enters the chute from the conveyor belt 2, if the package deviates in the sliding area 131, the first buffer 132 and the second buffer 133 can guide the package back to the normal path. For example, a heavy electrical appliance package deviates to one side due to inertia when entering the chute. The inclined first buffer 132 and the second buffer 133 can buffer and guide it, so that it slides down smoothly, avoiding collision with the side wall 10b, causing damage to the package or blocking the chute.

[0136] The friction coefficients of the first buffer zone 132 and the second buffer zone 133 are greater than the friction coefficient of the sliding zone 131. In terms of material selection, the sliding zone 131 can be made of smooth metal or plastic material 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 are made of materials that increase friction, such as rubber coating materials with special textures.

[0137] When the friction coefficient of the first buffer zone 132 and the second buffer zone 133 is greater than the friction coefficient of the sliding zone 131, the difference in friction coefficients allows the goods to quickly decelerate and adjust the direction of movement when entering the buffer zone, preventing the goods from losing control due to excessive speed. At the same time, the control ability of the chute over the movement of goods is enhanced, ensuring that the goods are effectively buffered and guided in the buffer zone, reducing the risk of the goods colliding with the side wall 10b or rushing out of the chute due to excessive speed. When the friction coefficient of the first buffer zone 132 and the second buffer zone 133 is equal to the friction coefficient of the sliding zone 131, the production and manufacturing of the material chute 1 is convenient.

[0138] For example, during the express parcel sorting process, when the parcels slide down at high speed and enter the buffer zone, the larger friction coefficient can quickly reduce the parcel speed, allowing it to slide down smoothly and avoid collision and damage. For example, during express peak periods such as "Double 11", a large number of parcels are quickly transported in the chute. The larger friction coefficient of the buffer zone can effectively control the parcel speed and ensure the smooth progress of the sorting work.

[0139] See also Figures 5 to 7 In one embodiment, the first buffer area 132 includes a first sub-buffer area 132 a and a second sub-buffer area 132 b connected to each other, and the first sub-buffer area 132 a is located between the sliding area 131 and the second sub-buffer area 132 b.

[0140] Specifically, the first buffer zone 132 is composed of a first sub-buffer zone 132a and a second sub-buffer zone 132b connected to each other, and the first sub-buffer zone 132a is located between the sliding zone 131 and the second sub-buffer zone 132b. In terms of shape, the first sub-buffer zone 132a may be a relatively gentle curve, and the second sub-buffer zone 132b may be a curve with a greater curvature. In terms of material, materials with different surface treatments may be selected according to different friction coefficient requirements, such as smoothing the surface of the first sub-buffer zone 132a to reduce the friction coefficient; adding textures to the surface of the second sub-buffer zone 132b to increase the friction coefficient, or smoothing the surface of the second sub-buffer zone 132b to reduce the friction coefficient; adding textures to the surface of the first sub-buffer zone 132a to increase the friction coefficient, and there is no specific limitation on this.

[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 in sequence to jointly buffer and guide the goods. Different curvature designs provide differentiated buffering effects for goods with different speeds and energies. Among them, for goods with faster speeds and greater energy, the larger curvature of the second sub-buffer zone 132b can provide a stronger buffering effect, so that the speed and movement direction of the goods can be effectively adjusted; while the first sub-buffer zone 132a first performs preliminary buffering on the goods to ensure that the goods enter the second sub-buffer zone 132b smoothly.

[0142] For example, in an express delivery sorting center, large and heavy parcels slide down the chute at a faster speed. When these parcels enter the first buffer zone 132, the first sub-buffer zone 132a initially decelerates them, and then the second sub-buffer zone 132b further buffers and guides the parcels with a greater curvature, so that they slide down smoothly, thereby preventing the parcels from rushing out of the chute or damaging other goods due to excessive speed.

[0143] See also Figures 5 to 7 In one embodiment, the second buffer area 133 includes a third sub-buffer area 133 a and a fourth sub-buffer area 133 b connected to each other, and the third sub-buffer area 133 a is located between the sliding area 131 and the fourth sub-buffer area 133 b.

[0144] Specifically, the second buffer zone 133 is composed of a third sub-buffer zone 133a and a fourth sub-buffer zone 133b connected to each other, and the third sub-buffer zone 133a is 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, and the fourth sub-buffer zone 133b is a curve with a greater curvature. In terms of material, similar to the first buffer zone 132, it can be selected according to the friction coefficient requirements, such as the third sub-buffer zone 133a uses a relatively smooth material, and the fourth sub-buffer zone 133b uses a material that increases friction, or the fourth sub-buffer zone 133b uses a relatively smooth material, and the third sub-buffer zone 133a uses a material that increases friction, and there is no specific limitation on this.

[0145] Furthermore, the curvature of the fourth sub-buffer zone 133b is greater than the curvature of the third sub-buffer zone 133a. With such a configuration, for goods with greater energy, the greater curvature of the fourth sub-buffer zone 133b can provide a stronger buffering effect, and work in conjunction with the third sub-buffer zone 133a to ensure that the goods are adequately buffered and guided in the second buffer zone 133, thereby avoiding problems with the goods due to excessive speed or deviation in the movement trajectory. The third sub-buffer zone 133a and the fourth sub-buffer zone 133b cooperate with each other to further buffer and guide the goods, thereby enhancing the ability of the second buffer zone 133 to adjust the movement trajectory of the goods.

[0146] For example, in an automobile parts manufacturing plant, heavier metal parts have greater kinetic energy during the chute transmission process. The third sub-buffer zone 133a first performs preliminary buffering on the parts, and then the fourth sub-buffer zone 133b further decelerates and adjusts the direction with a greater curvature to ensure that the parts pass through the second buffer zone 133 safely and smoothly, preventing the parts from being damaged by collision.

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

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

[0149] Specifically, the friction coefficient of the first sub-buffer zone 132a is less than or equal to the friction coefficient of the second sub-buffer zone 132b. In terms of material selection, the first sub-buffer zone 132a can use materials with low friction coefficients, such as polytetrafluoroethylene coating materials, so that the goods can quickly enter the buffer zone; the second sub-buffer zone 132b uses materials with high friction coefficients, such as rubber materials with special textures, to enhance the deceleration and guidance of the goods. Among them, the smaller friction coefficient of the first sub-buffer zone 132a facilitates the rapid entry of the goods into the buffer zone and reduces the jamming of the goods when entering; the larger friction coefficient of the second sub-buffer zone 132b can effectively reduce the speed of the goods, adjust the movement trajectory of the goods, and allow the goods to pass through the buffer zone smoothly. By setting different friction coefficients, the movement state of the goods at different stages can be adjusted to achieve precise control of the movement speed and trajectory of the goods. Of course, the friction coefficient of the first sub-buffer zone 132a can be set to be equal to the friction coefficient of the second sub-buffer zone 132b. At this time, the first sub-buffer zone 132a and the second sub-buffer zone 132b can be set with the same friction coefficient material.

[0150] For example, in an electronic product manufacturing workshop, when small electronic components are conveyed in a slide, the low friction coefficient of the first sub-buffer zone 132a can ensure that the electronic components quickly enter the buffer zone to avoid stagnation of the components; the high friction coefficient of the second sub-buffer zone 132b can decelerate the electronic components smoothly to prevent the components from being damaged or deviating from the trajectory due to excessive speed.

[0151] Similarly, specifically, the friction coefficient of the third sub-buffer zone 133a is less than or equal to the friction coefficient of the fourth sub-buffer zone 133b. In terms of material selection, the third sub-buffer zone 133a may use a material with a low friction coefficient, such as a metal material with a smooth surface, to facilitate the rapid entry of goods; the fourth sub-buffer zone 133b may use a material with a high friction coefficient, such as a plastic material with an anti-slip texture, to achieve deceleration and guidance of goods, or the third sub-buffer zone 133a may use a material with a high friction coefficient, and the fourth sub-buffer zone 133b may use a material with a low friction coefficient, and there is no specific limitation on this.

[0152] For example, the smaller friction coefficient of the third sub-buffer 133a facilitates the rapid entry of the goods into the fourth sub-buffer 133b, reducing the jamming of the goods when entering; the larger friction coefficient of the fourth sub-buffer 133b can effectively reduce the speed of the goods, adjust the movement trajectory of the goods, and allow the goods to pass smoothly through the second buffer 133. The setting of different friction coefficients can be adjusted according to the movement state of the goods at different stages of the second buffer 133, so as to achieve fine control of the movement speed and trajectory of the goods. Of course, the friction coefficient of the third sub-buffer 133a and the friction coefficient of the fourth sub-buffer 133b can also be configured to be the same, so as to facilitate the uniform deceleration control of the goods and the production of the material chute 1.

[0153] For example, in a precision instrument manufacturing workshop, when tiny and expensive precision instruments are transported in a slide, the low friction coefficient of the third sub-buffer zone 133a can ensure that the instruments quickly enter the fourth sub-buffer zone 133b to avoid stagnation of the instruments; the high friction coefficient of the fourth sub-buffer zone 133b can decelerate the instruments smoothly to prevent the instruments from being damaged or deviating from the trajectory due to excessive speed.

[0154] See also Figures 5 to 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, and the first initial zone 132b1, the first cargo sliding zone 132b2, and the first extension zone 132b3 are arranged in sequence along the sliding direction of the slideway 13; the friction coefficient of the first cargo sliding zone 132b2 is not less than the friction coefficient 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-in zone 133b2 and a second extension zone 133b3, and the second initial zone 133b1, the second cargo sliding-in zone 133b2 and the second extension zone 133b3 are arranged in sequence along the sliding direction of the slide 13; the friction coefficient of the second cargo sliding-in zone 133b2 is not less than the friction coefficient of the second initial zone 133b1 and the second extension zone 133b3.

[0156] Specifically, the second sub-buffer zone 132b includes a first initial zone 132b1, a first cargo slide-in zone 132b2, and a first extension zone 132b3 arranged in sequence along the sliding direction of the slideway 13, wherein the width of the first cargo slide-in zone 132b2 can be set to be greater than the first initial zone 132b1 and the first extension zone 132b3. In terms of shape, the first cargo slide-in zone 132b2 is a wider rectangle or trapezoid, and the first initial zone 132b1 and the first extension zone 132b3 are relatively narrow. In terms of material, the surface roughness can be adjusted according to the functional requirements of different areas, such as the first cargo slide-in zone 132b2 can be made of smooth material to facilitate the rapid entry of cargo; the first initial zone 132b1 and the first extension zone 132b3 can appropriately increase friction to better guide the cargo. This design of width variation facilitates the smooth entry of cargo into the second sub-buffer zone 132b, while achieving precise guidance when the cargo enters and leaves, and optimizing the movement process of the cargo in the second sub-buffer zone 132b. Among them, the friction coefficient of the first cargo sliding area 132b2 is not less than the friction coefficient of the first initial area 132b1 and the first extension area 132b3, and can be configured so that the friction coefficient of the first cargo sliding area 132b2 is greater than or equal to the friction coefficient of the first initial area 132b1 and the first extension area 132b3.

[0157] Furthermore, the wider first cargo sliding-in area 132b2 reduces the risk of collision when cargo enters the buffer zone, while the narrower first initial area 132b1 and the first extension area 132b3 help to precisely control the movement direction of cargo, 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 in the chute, the wider first cargo sliding area 132b2 allows the books to easily enter the buffer zone, preventing the edge of the book from colliding with the edge of the buffer zone; the narrower first initial area 132b1 and the first extension area 132b3 can prevent the books from excessively deflecting in the buffer zone, ensuring that the books slide down neatly, facilitating subsequent sorting and sorting.

[0159] In addition, the friction coefficient of the first cargo sliding-in area 132b2 is greater than or equal to the friction coefficient of the first initial area 132b1 and the first extension area 132b3. In terms of material selection, the first initial area 132b1 and the first extension area 132b3 can use materials with different friction coefficients and low friction coefficients, such as polytetrafluoroethylene coating materials, so that the cargo can enter quickly; the first cargo sliding-in area 132b2 uses materials with high friction coefficients, such as rubber materials with special textures, to enhance the deceleration and guidance of the cargo. By setting different friction coefficients and adjusting the movement state of the cargo at different stages, precise control of the cargo movement speed and trajectory can be achieved.

[0160] See also Figure 5, 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 in sequence along the sliding direction of the slideway 13, wherein the width of the second cargo sliding zone 133b2 is greater than the second initial zone 133b1 and the second extension zone 133b3, and is greater than the third sub-buffer zone 133a. In terms of shape, the second cargo sliding zone 133b2 is a wider area, and the second initial zone 133b1 and the second extension zone 133b3 are relatively narrow. In terms of material, the surface characteristics can be adjusted according to the functional requirements of different areas, such as the second cargo sliding zone 133b2 uses a smooth material, and the second initial zone 133b1 and the second extension zone 133b3 use a material that increases friction.

[0161] The wider second cargo sliding-in area 133b2 reduces the risk of collision when cargo enters the fourth sub-buffer zone 133b, while the narrower second initial area 133b1 and second extension area 133b3 help to accurately control the direction of cargo movement, ensuring that cargo moves more stably and orderly in the second buffer zone 133. This width design facilitates cargo to enter the fourth sub-buffer zone 133b, while achieving precise guidance when cargo enters and leaves, and optimizing the overall movement process of cargo in the second buffer zone 133. Among them, the friction coefficient of the second cargo sliding-in area 133b2 is not less than the friction coefficient of the second initial area 133b1 and the second extension area 133b3, and can be configured so that the friction coefficient of the second cargo sliding-in area 133b2 is greater than or equal to the friction coefficient of the second initial area 133b1 and the second extension area 133b3.

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

[0163] Furthermore, the friction coefficients of the second initial area 133b1, the second cargo sliding area 133b2, and the second extension area 133b3 are different. Similarly, in terms of material selection, the second initial area 133b1 and the second extension area 133b3 can use materials with different friction coefficients and low friction coefficients, such as polytetrafluoroethylene coating materials, so that the cargo can enter quickly; the second cargo sliding area 133b2 uses materials with high friction coefficients, such as rubber materials with special textures, to enhance the deceleration and guidance of the cargo. By setting different friction coefficients and adjusting the movement state of the cargo at different stages, precise control of the cargo movement speed and trajectory can be achieved.

[0164] See also Figure 1 and Figure 8In the present application, the logistics sorting chute is usually used in conjunction with the conveyor belt 2, and the chute entrance 11 side of the chute body 10 abuts against the side of the conveyor belt 2. When the goods need to be separated from the conveyor belt 2 and enter the logistics sorting chute for sorting, the goods can be divided into heavy weight goods, medium weight goods and light weight goods according to their weight.

[0165] See also Figure 1 In the figure, X refers to the movement direction of the conveyor belt 2, and Y refers to the movement direction of the goods when they are forced into the material chute 1.

[0166] See also Figure 8 , S1 in the figure is the sliding path S1 of heavy goods. Due to its own gravity, heavy goods have a large initial kinetic energy when entering the sliding area 131 of the chute from the conveyor belt 2. After entering the sliding area 131, due to the large gravitational potential energy Ep=mgh (m is the mass of the goods, g is the acceleration of gravity, and h is the height difference), the speed increases rapidly during the sliding process. When approaching the first buffer zone 132, due to the fast speed and large kinetic energy, it is easy to deviate from the sliding area 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, and the deceleration effect on the goods is weak, so the goods pass quickly. Arriving at the second sub-buffer zone 132b, because of its large curvature and large friction coefficient, according to the friction work formula W=Fs=mgμs (μ is the sliding friction coefficient, s is the sliding distance), the goods are subject to large resistance, the speed is rapidly reduced, and the direction of movement is adjusted. After leaving the first buffer zone 132, if the speed is still large, it may rush to the second buffer zone 133. In the second buffer zone 133, the goods first pass through the third sub-buffer zone 133a for preliminary buffering, and then enter the fourth sub-buffer zone 133b. The fourth sub-buffer zone 133b has a larger curvature and a larger friction coefficient, and further decelerates and adjusts the trajectory of the goods to reduce the speed to a suitable range, and finally smoothly slides out of the chute from the sliding zone 131 to the destination. Alternatively, in the second buffer zone 133, the goods may only pass through the third buffer zone, and further decelerate and adjust the trajectory of the goods to reduce the speed to a suitable range, and finally smoothly slide out of the chute from the sliding zone 131 to the destination.

[0167] See also Figure 8, S2 in the figure is the sliding path S2 of medium-weight cargo. After the medium-weight cargo enters the sliding area 131 of the chute, the gravitational potential energy is converted into kinetic energy, and the speed gradually increases. When moving in the sliding area 131, the speed is relatively small compared to the heavy-weight cargo. When entering the first buffer zone 132, the first sub-buffer zone 132a is initially decelerated, and then the speed and direction are further adjusted in the second sub-buffer zone 132b. Since the kinetic energy of medium-weight cargo is not as large as that of heavy-weight cargo, the speed has been effectively controlled after passing through the first buffer zone 132, and generally it will not rush into the second buffer zone 133, but will directly slide out of the chute at a suitable speed from the sliding area 131. If it rushes into the second buffer zone 133, it will rush into the third sub-buffer zone 133a for further buffering, further decelerate the cargo and adjust the trajectory, so that its speed is reduced to a suitable range, and finally smoothly slide out of the chute from the sliding area 131 to the destination. In this process, the relationship between gravitational potential energy, kinetic energy and friction work still follows the above formula, and the energy and movement trajectory of the cargo are adjusted by the change of the friction coefficient in different areas.

[0168] See also Figure 8 , S3 in the figure is the sliding path S3 of the low-weight cargo. After the low-weight cargo enters the sliding area 131 of the chute, the gravitational potential energy is small. In the sliding area 131, it is mainly affected by friction. Because the friction consumes energy, its speed increases slowly. The low-weight cargo basically moves in a parabolic motion in the sliding area 131. Due to its light weight, it is relatively more affected by external interference, but because of its slow speed, it generally does not deviate from the sliding area 131 and enter the buffer zone. Finally, it slides out of the chute from the exit of the sliding area 131 at a relatively stable and low speed to reach the destination. In the whole process, the changes in the kinetic energy, gravitational potential energy and friction work of the low-weight cargo are relatively gentle. According to the formula calculation, its energy change is mainly reflected in overcoming the friction work, so that the cargo maintains a relatively stable state of motion until it slides out of the chute.
