Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of goods conveying, and more particularly relates to a chute and a goods conveying mechanism. BACKGROUND

[0002] With the continuous updating and development of modern information technology, remote conveying / delivering goods relying on information technology has become a core logistics transportation mode. Generally, in the process of whole or sorting goods at the departure place, transfer place or destination, the goods are conveyed by full-automatic or semi-automatic assembly line equipment, for example, the goods are conveyed to the chute by using a conveyor belt or manual mode.

[0003] The chute has a certain extension length, so that the goods are limited and guided to slide along the length direction of the chute by using the inner wall of the chute, and the chute has a certain inclination along the gravity direction, so that the goods can slide out of the chute along the length direction of the chute by using the gravity potential energy possessed by the goods. In this way, under the combined action of the guiding of the chute structure and the gravity potential energy possessed by the goods, the goods enter the chute from the higher port of the chute, and slide out of the chute from the lower port of the chute.

[0004] However, different goods have different volumes, densities, materials or construction modes, different goods have different weights, and different goods have different initial speeds when entering the chute from the higher port of the chute. In other words, different goods have different gravity potential energy in the chute, different goods have different friction between the goods and the inner wall of the chute, and different goods have different kinetic energy in the chute, which finally leads to different sliding trajectories of different goods in the chute, and also leads to the risk that part of the goods cannot slide out of the chute from the lower port.

[0005] Based on the different weights and different volumes of different goods, the goods are distinguished by different pressure intensities of different goods on the chute, and are divided into low-energy goods, medium-energy goods and high-energy goods. Among them, the energy here can refer to the energy possessed by the goods in the movement process, mainly including kinetic energy and potential energy, which is a physical quantity for measuring the work function possessed by the goods due to the movement state and relative position. Or, the energy here can refer to the energy density of the goods, which is positively correlated with the density of the goods. Different goods density energy has different pressure intensities on the chute, and the goods are divided according to the different pressure intensities.

[0006] The low-energy cargo usually has a small volume, a light weight, a low initial speed when entering the chute from the higher port, is relatively easy to operate in the process of whole cargo or sorting, has a small load requirement and space occupation requirement for the chute, has a low kinetic energy when sliding in the chute, that is, a relatively slow sliding speed, and a relatively small friction force from the inner wall of the chute, and thus does not cause a large impact on the chute. For example, the low-energy cargo can be a package containing several clothes, and the weight is about 1 kg. Since the low-energy cargo has a small gravitational potential energy and a limited initial speed when entering the chute, it is easy to stop in the chute when sliding, and thus cannot reach the lower port of the chute or directly stop at the lower port, which finally hinders the smooth completion of the sorting work.

[0007] The medium-energy cargo usually refers to a cargo with an energy between the low-energy cargo and the high-energy cargo, has a certain weight and volume, has a medium kinetic energy when sliding in the chute, and has certain operation specification requirements and matters needing attention in the sorting process. The initial speed when entering the chute from the higher port is not low nor high, and since the medium-energy cargo has a certain speed and kinetic energy when sliding in the chute, it can collide slightly with other cargos, but generally will not cause serious damage, has a certain pressure bearing requirement and space occupation requirement for the chute, but within the normal bearing range. For example, the medium-energy cargo can be an express package containing a small-sized sweeping robot, and the weight is generally several kilograms. Since the medium-energy cargo has a certain speed and kinetic energy when sliding in the chute, it will alternately touch the two inner walls of the chute along the width direction during the sliding process, but will not cause a serious impact on the inner wall of the chute.

[0008] The high-energy cargo has a large weight, and the volume is also large, has a large kinetic energy when sliding in the chute, has certain special equipment requirements and operation process requirements in the transportation, cargo handling and sorting process, for example, special manpower support or technical support is needed in the sorting and delivery process. The initial speed when entering the chute from the higher port is large, and the kinetic energy generated can be very large, which can cause damage to the chute, is easy to collide seriously with other cargos during the sliding process, causes damage to the high-energy cargo itself or other cargos, and has a high pressure bearing requirement and space occupation requirement for the chute. For example, the high-energy cargo can be an express package containing small-sized furniture, household appliances or fitness equipment, and the weight is generally several tens of kilograms. Since the high-energy cargo has a certain speed and kinetic energy when sliding in the chute, it will alternately touch the two inner walls of the chute along the width direction during the sliding process, and can cause a serious impact on the inner wall of the chute.

[0009] For the above medium energy goods and high energy goods, when sliding, there is a certain friction between the left and right side walls and the bottom wall of the chute and the inner wall of the chute, which depends on the specific material of the inner wall of the chute. If the friction is too large, combined with the weight and volume of the medium energy goods and high energy goods, there is a risk that the goods may stop in the chute or cannot smoothly slide out of the chute outlet. If the friction is too small, combined with the weight and volume of the medium energy goods and high energy goods, there is a risk that the goods may rush out of the lower port or out of the left and right side walls of the chute at a high speed, thereby causing problems of sorting safety and goods safety.

[0010] It should be noted that the above comparison between low energy goods, medium energy goods and high energy goods is only an illustrative description of the differences between the three. Low energy goods, medium energy goods and high energy goods can be distinguished within a certain threshold range, for example, goods can be divided into low energy goods, medium energy goods and high energy goods within a weight threshold range of 0-10kg. Goods can also be divided into low energy goods, medium energy goods and high energy goods within a weight threshold range of 0-100kg. Goods can also be divided into low energy goods, medium energy goods and high energy goods within a weight threshold range of 100kg-1000kg. The reference to low energy goods, medium energy goods and high energy goods here is only to describe the defects of the prior art. There is no indication of energy division for goods in the actual application of the prior art.

[0011] In the prior art, the above low energy goods, medium energy goods and high energy goods are generally transported by the same chute. The inner wall of the chute has a uniform friction force, which cannot simultaneously adapt to the transportation of the three energy goods. The uniform friction force causes at least one of the low energy goods, medium energy goods and high energy goods to stop, be thrown out from the sides or rush out of the chute at a high speed during sliding transportation, thereby causing technical problems of normal sorting failure or inability to guarantee goods safety and sorting safety.

[0027] In some embodiments, the chute has an inner concave side and an outer convex side arranged opposite along the width direction;

[0040] The goods transportation mechanism provided by the application has the same beneficial effects as the chute provided by the application compared with the prior art. The non-uniformly arranged friction force can simultaneously adapt to the transportation of at least two energy goods. The non-uniformly arranged friction force limits the goods in the constrained friction zone during the sliding transportation, so that the goods cannot be thrown out from both sides or rush out of the chute at a large speed in the middle of the way, which causes the technical problems of unable to normally sort or unable to guarantee the safety of the goods and the safety of sorting, and the friction zone considers the required work function to ensure that it normally reaches the guide outlet, and the goods do not stop.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0058] Now the chute 100 and the cargo conveying mechanism provided by the embodiments of the present application will be described. Among them, the first embodiment, the second embodiment and the third embodiment are described in detail respectively according to the division of the friction area, and the fourth embodiment is described in detail from the structural point of view of the chute 100. Among them, in actual application, the first embodiment, the second embodiment and the third embodiment can be used in combination with the fourth embodiment respectively.

[0059] Please refer to Figures 1 to 6The first embodiment of the application provides a chute 100 which is arranged obliquely relative to a horizontal plane. The chute 100 comprises a guide-in groove section 101, an arc-shaped groove section 102 and a guide-out groove section 103 which are sequentially communicated along an extension direction a of the chute 100. The arc-shaped groove section 102 is arc-shaped, and the guide-in groove section 101 and the guide-out groove section 103 are arranged at an angle. An end of the guide-in groove section 101 away from the arc-shaped groove section 102 is a guide-in opening 100a, and the goods to be conveyed are guided into the chute 100 from the guide-in opening 100a. An end of the guide-out groove section 103 away from the arc-shaped groove section 102 is a guide-out opening 100b, and the goods to be conveyed are guided out of the chute 100 from the guide-out opening 100b. The height position of the guide-in opening 100a is higher than the height position of the guide-out opening 100b.

[0060] In the width direction b of the chute 100 and the direction from the center of the chute 100 to the width edge of the chute 100, the inner wall of the chute 100 has at least a first friction zone 1001 and a second friction zone 1002. The first friction zone 1001 and the second friction zone 1002 are both arranged along the extension direction a, and the friction coefficient of the second friction zone 1002 is greater than the friction coefficient of the first friction zone 1001. The first friction zone 1001 is used to limit the trajectory of the goods with a first energy density within the first friction zone 1001, and the second friction zone 1002 is used to limit the trajectory of the goods with a second energy density within the second friction zone 1002 and the first friction zone 1001. The first friction zone 1001 and the second friction zone 1002 are also used to make the guide-out speed of the goods with the first energy density and the goods with the second energy density consistent at the guide-out opening 100b. The second energy density is greater than the first energy density, and the energy density is the energy consumed by the unit volume of goods when slidingly conveyed in the chute 100.

[0061] The first friction zone 1001 and the second friction zone 1002 are both arranged along the extension direction a, so that the goods can be guided along the extension direction a, and the friction coefficient of the second friction zone 1002 is greater than the friction coefficient of the first friction zone 1001, which can provide different friction forces for the goods.

[0062] In this way, the same chute 100 can convey at least the goods with the first energy density and the goods with the second energy density. The inner wall of the chute 100 has a non-uniformly arranged friction force, which can simultaneously adapt to the conveying of at least two kinds of energy goods. The non-uniformly arranged friction force limits the goods in the constrained friction zone during the sliding conveying process, so that the goods do not appear to be thrown out from both sides or rush out of the chute 100 at a large speed, which causes the technical problems of unable to normally sort or unable to guarantee the safety of the goods and the safety of the sorting, and the friction zone considers the required work function to ensure that it normally reaches the guide-out opening 100b, so that the goods do not appear to be stagnant.

[0063] The first energy density cargo and the second energy density cargo can be low energy cargo and medium energy cargo, medium energy cargo and high energy cargo, or low energy cargo and high energy cargo, respectively.

[0064] The different cargos have different volumes, densities, materials or construction methods, different weights, and different initial speeds when entering the chute 100 from the guide inlet 100a. In other words, the different cargos have different gravitational potential energy in the chute 100, different friction between the cargo and the inner wall of the chute 100, and different kinetic energy in the chute 100, which ultimately results in different sliding trajectories of the different cargos in the chute 100, and the risk that some cargos cannot slide out of the chute 100 from the guide outlet 100b.

[0065] Based on the different weights and volumes of different cargos, the cargos are classified into low energy cargo, medium energy cargo and high energy cargo by the different pressure of different cargos on the chute 100. The energy here can refer to the energy of the cargo during movement, mainly including kinetic energy and potential energy, which is a physical quantity that measures the work function of the cargo due to the movement state and relative position. Alternatively, the energy here can refer to the energy density of the cargo, which is positively correlated with the density of the cargo. Different cargo density energy has different pressure on the chute 100, and the cargos are classified according to the different pressure.

[0066] The low energy cargo usually has a small volume and light weight, a low initial speed when entering the chute 100 from the guide inlet 100a, and is relatively easy to operate during the whole cargo or sorting process. The low energy cargo has a small load requirement and space requirement for the chute 100, a low kinetic energy when sliding in the chute 100, that is, a relatively slow sliding speed, and a relatively small frictional force from the inner wall of the chute 100, which does not cause a large impact on the chute 100.

[0067] The medium energy cargo usually refers to the cargo with energy between the medium energy cargo and the high energy cargo, which has a certain weight and volume, and a medium kinetic energy when sliding in the chute 100. The medium energy cargo has certain operation specification requirements and matters needing attention during the sorting process. The initial speed of the medium energy cargo when entering the chute 100 from the guide inlet 100a is not low or high. Since the medium energy cargo has a certain speed and kinetic energy when sliding in the chute 100, it may collide slightly with other cargos, but usually does not cause serious damage. The medium energy cargo has a certain pressure requirement and space requirement for the chute 100, but within the normal bearing range.

[0068] The high-energy cargo has a large weight, and its volume is often large, and its kinetic energy is large when sliding in the chute 100. It has certain special equipment requirements and operation process requirements in the transportation, cargo handling and sorting process, such as providing special manpower support or technical support in the sorting and delivery process. The initial speed of the cargo entering the chute 100 from the guide inlet 100a is large, and the kinetic energy generated is very large, which can cause damage to the chute 100, and is easy to cause serious collision with other cargos in the sliding process, resulting in damage to the high-energy cargo itself or other cargos, and has a high pressure requirement and space requirement for the chute 100.

[0069] It should be noted that the above comparison among the low-energy cargo, the medium-energy cargo and the high-energy cargo is only an illustrative description of the differences among the three, and is not an absolute definition and setting. The definition method can be determined by considering one or more of the weight, volume, material, pressure, and energy density. The embodiments of the present application do not make more specific constraints. In addition, the low-energy cargo, the medium-energy cargo and the high-energy cargo can be defined within a certain threshold range, and the embodiments of the present application do not make more specific constraints. For example, the cargos can be divided into low-energy cargos, medium-energy cargos and high-energy cargos within a weight threshold range of 0-10 kg. The cargos can also be divided into low-energy cargos, medium-energy cargos and high-energy cargos within a weight threshold range of 0-100 kg. The cargos can also be divided into low-energy cargos, medium-energy cargos and high-energy cargos within a weight threshold range of 100 kg-1000 kg.

[0070] For another example, in some embodiments, the pressure P of the cargo on the inner wall of the chute 100 is used to define the energy density of the cargo, and the energy density of the cargo is proportional to its density. The natural density of liquid water is set as 1000 g / dm3 as a standard. The formula is ρ=m / V, where m is the mass of the cargo, and V is the volume of the cargo. The friction per unit area of the cargo is positively correlated with the pressure, and the pressure of 1 dm is set as P1=980 pa as a standard. The pressure of the cargo on the inner wall of the chute 100 is set as P. When P>P1, the cargo is a cargo with a third energy density, or can be a high-energy cargo. When 1 / 3P1≤P≤P1, the cargo is a cargo with a second energy density, or can be a medium-energy cargo. When P<1 / 3P1, the cargo is a cargo with a first energy density, or can be a low-energy cargo.

[0071] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002, which are arranged on both sides of the first friction zone 1001 along the width direction b. The two second friction zones 1002 are used to limit the trajectory of the cargo with a second energy density between the two outer edges of the two second friction zones 1002 away from each other along the width direction b.

[0072] In some embodiments, the inner wall of the chute 100 further has a third friction zone 1003; in the width direction b of the chute 100, and in the direction from the center of the chute 100 to the width edge of the chute 100, the first friction zone 1001, the second friction zone 1002, and the third friction zone 1003 have a greater coefficient of friction than the second friction zone 1002. The third friction zone 1003 is used to restrict the trajectory of the cargo with the third energy density within the third friction zone 1003, the second friction zone 1002, and the first friction zone 1001, and to make the discharge speed of the cargo with the third energy density at the outlet 100b tend to be consistent with the discharge speed of the cargo with the first energy density and the cargo with the second energy density at the outlet 100b; wherein, the third energy density is greater than the second energy density.

[0073] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002 and two third friction zones 1003; the two second friction zones 1002 are disposed on both sides of the first friction zone 1001 along the width direction b, and the two second friction zones 1002 are used to restrict the trajectory of the goods with the second energy density between two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b; the two third friction zones 1003 are disposed on both sides of the second friction zones 1002 along the width direction b, and the two third friction zones 1003 are used to restrict the trajectory of the goods with the third energy density between two outer edges of the two third friction zones 1003 that are opposite to each other along the width direction b.

[0074] like Figure 3 The trajectory 1 shown restricts the trajectory of the cargo with the first energy density to two opposite outer edges of the first friction zone 1001 along the width direction b. Figure 3 The trajectory 2 shown restricts the trajectory of the cargo with the second energy density to two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b. Figure 2 The trajectory 3 shown restricts the trajectory of the cargo with the third energy density to the two outer edges of the two third friction zones 1003 that are opposite to each other along the width direction b.

[0075] In some embodiments, the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 each have a starting end and a terminal end along the extension direction a. The starting end and the terminal end of the first friction zone 1001 are arranged flush with the mouth edge of the inlet 100a and the mouth edge of the outlet 100b, respectively; the starting end of the second friction zone 1002 is arranged spaced apart from the mouth edge of the inlet 100a along the extension direction a, and the starting end of the third friction zone 1003 is arranged on the side of the starting end of the second friction zone 1002 away from the inlet 100a, and the terminal ends of the second friction zone 1002 and the third friction zone 1003 are arranged flush with the mouth edge of the outlet 100b.

[0076] That is, at the inlet 100a of the chute 100, the first friction zone 1001 occupies the entire width dimension of the chute 100 along the width direction b of the chute 100, and the goods of different energy densities entering the chute 100 from the inlet 100a all enter the first friction zone 1001 first, and after sliding a distance in the first friction zone 1001, they start to contact the second friction zone 1002 and the third friction zone 1003 according to different energy densities, and are autonomously screened by the second friction zone 1002 and the third friction zone 1003 and their trajectory ranges are limited.

[0077] In some embodiments, the slot opening of the chute 100 is arranged open upward, the first friction zone 1001 is arranged opposite the slot opening along the height direction c of the chute 100, the second friction zone 1002 is connected at an obtuse angle relative to the first friction zone 1001, the third friction zone 1003 is connected at an obtuse angle relative to the second friction zone 1002, and the third friction zone 1003 and the first friction zone 1001 are connected perpendicularly.

[0078] Along the width direction b of the chute 100, the cross section of the chute 100 is generally U-shaped, the middle region is the first friction zone 1001, the first friction zone 1001 generally occupies most of the region of the bottom wall of the chute 100, the two side walls of the chute 100 are arranged on both sides of the bottom wall along the width direction b, and the side wall and the bottom wall are smoothly connected by an arc-shaped chamfer.

[0079] Among them, the second friction zone 1002 can occupy a small part of the side region of the bottom wall along the width direction b, and a small part of the region of the side wall close to the bottom wall, that is, the second friction zone 1002 covers the region of the arc-shaped chamfer. The third friction zone 1003 can occupy most of the region of the side wall close to the slot opening.

[0080] It should be noted that the occupying dimensions of the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 along the width direction b can be adaptively increased or decreased according to different requirements of the width of each region, and are not limited to the size occupying scheme described above.

[0081] In some embodiments, the chute 100 has an inner concave side 1004 and an outer convex side 1005 arranged oppositely along the width direction b; the two second friction zones 1002 have a consistent extension along the width direction b; the third friction zone 1003 on the outer convex side 1005 of the chute 100 has a greater extension along the width direction b than the third friction zone 1003 on the inner concave side 1004 of the chute 100; and / or, the first friction zone 1001 has a greater extension along the width direction b than the second friction zone 1002 and the third friction zone 1003.

[0082] For example, the first friction zone 1001 can have a dimension along the width direction b that is much greater than the extension of the second friction zone 1002 along the width direction b, even twice or more than the extension of the second friction zone 1002 along the width direction b. Similarly, the first friction zone 1001 can have a dimension along the width direction b that is much greater than the extension of the third friction zone 1003 along the width direction b, even twice or more than the extension of the third friction zone 1003 along the width direction b.

[0083] In some embodiments, the chute 100 has an inner concave side 1004 and an outer convex side 1005 arranged oppositely along the width direction b; on the side of the inner concave side 1004, the second friction zone 1002 and the third friction zone 1003 are simultaneously convex towards the outer convex side 1005, and the convex trend is simultaneously matched to the convex trend of the inner concave side 1004 towards the outer convex side 1005; and, the convex is divided by a perpendicular line d perpendicular to the tangent line at the vertex of the convex into a first convex portion 1004a and a second convex portion 1004b on both sides of the perpendicular line d, the first convex portion 1004a is adjacent to the side of the inlet 100a, and the second convex portion 1004b is connected with the outlet 100b.

[0084] On the side of the outer convex side 1005 and along the extension direction a of the chute 100, the second friction zone 1002 and the third friction zone 1003 are both first convex towards the inner concave side 1004 and then both concave towards the outer convex side 1005, thereby forming a continuous convex portion 1005a and a concave portion 1005b; and, the part of the first convex portion 1004a adjacent to the inlet 100a is arranged staggered with the convex portion 1005a along the extension direction a, and the concave portion 1005b is arranged opposite to the second convex portion 1004b and the part of the first convex portion 1004a close to the perpendicular line d along the width direction b.

[0085] The first protrusion 1004a is used to limit the trajectory of the second energy density goods and the third energy density goods for the first time, the part on the concave portion 1005b close to the convex portion 1005a is used to limit the trajectory of the second energy density goods and the third energy density goods for the second time, and the second protrusion 1004b is used to limit the trajectory of the second energy density goods and the third energy density goods for the third time, so that the second energy density goods and the third energy density goods are smoothly guided out of the guide outlet 100b.

[0086] The first friction area 1001, the second friction area 1002 and the third friction area 1003 can be continuously extended along the extension direction a, or can be discontinuously extended. For example, in the second friction area 1002, the first protrusion 1004a and the second protrusion 1004b can be discontinuously arranged, and the goods can be limited in trajectory by the first protrusion 1004a and the second protrusion 1004b with a higher probability, so that the first protrusion 1004a and the second protrusion 1004b can not be arranged as a friction area, or can be arranged as the first friction area 1001. For example, in the third friction area 1003, the convex portion 1005a and the concave portion 1005b can be discontinuously arranged, and the goods can be limited in trajectory by the convex portion 1005a and the concave portion 1005b with a higher probability, so that the convex portion 1005a and the concave portion 1005b can not be arranged as a friction area, or can be arranged as the first friction area 1001 or the second friction area 1002.

[0087] In some embodiments, a coating layer is coated on the inner wall of the chute 100, the coating layer includes a base layer and particles doped in the base layer and having hardness; and the base layers in the first friction area 1001, the second friction area 1002 and the third friction area 1003 are the same or different, the particle size of the particles in the first friction area 1001 is smaller than the particle size of the particles in the second friction area 1002, and the particle size of the particles in the second friction area 1002 is smaller than the particle size of the particles in the third friction area 1003.

[0088] In some embodiments, the coating layer can be polytetrafluoroethylene, which has a very low friction coefficient, usually about 0.04, excellent chemical stability and corrosion resistance, and can be coated on the inner wall of the chute 100 to significantly reduce the friction between the goods and the wall, so that the goods can quickly and smoothly slide, especially suitable for light weight and friction sensitive goods, which can effectively control the sliding speed and reduce the jamming and blocking phenomenon. For example, the polytetrafluoroethylene can be coated at least in the first friction area 1001.

[0089] In some embodiments, the coating layer can be a polyurethane coating layer, which has good wear resistance, flexibility and impact resistance, and the friction coefficient can be adjusted within a certain range through the formula, generally between 0.3 and 0.6. At the same time, it has good oil resistance, water resistance and aging resistance. According to the characteristics of the goods and the use environment of the chute 100, the formula of the polyurethane coating layer can be adjusted to obtain a suitable friction coefficient, which can not only ensure a certain sliding speed of the goods, but also provide appropriate friction to prevent the goods from sliding too fast or out of control. It is suitable for goods of various weights and materials.

[0090] In some embodiments, the coating layer can be a silicone rubber coating layer, which has good elasticity, high temperature resistance and electrical insulation, and the friction coefficient is relatively low, generally between 0.2 and 0.4, and the surface is smooth, which can effectively reduce the friction between the goods and the wall. In addition, it also has excellent weather resistance and biocompatibility. For some goods that are easy to scratch or need to protect the surface, the silicone rubber coating layer can play a buffering and protective role, and its low friction coefficient helps the goods to slide smoothly in the chute 100, which can be used to transport electronic products, glass products and other fragile or easily scratched goods.

[0091] In some embodiments, the coating layer can be a ceramic coating layer, which has high hardness, high wear resistance, high temperature resistance and chemical stability, and the friction coefficient is between 0.3 and 0.5. The ceramic coating layer also has good self-lubricating property, which can reduce the friction loss to a certain extent, and is suitable for high-speed and high-frequency use of the chute 100, which can withstand large friction and impact force, reduce wear and tear, and prolong the service life of the chute 100. For heavy and fast sliding goods, the ceramic coating layer can provide a stable friction coefficient to ensure the controllability of the sliding track of the goods.

[0092] In some embodiments, the above-mentioned particulate matter can be glass beads, which have good wear resistance, chemical stability and sphericity, and the surface is smooth, which can effectively reduce the friction coefficient. The particle size of the glass beads is generally between several tens of microns and several hundred microns, which can be selected as needed. Uniformly distributing the glass beads on the inner wall of the chute 100 can form rolling friction between the goods and the wall, greatly reducing the friction and improving the sliding speed of the goods, and the uniform distribution of the glass beads helps to keep the sliding track of the goods stable.

[0093] In some embodiments, the above-mentioned particulate matter can be graphite particles, which have good lubricity and electrical conductivity, and a low friction coefficient, between 0.1 and 0.3. The graphite particles can form a lubricating film between the goods and the wall of the chute, reducing direct contact and friction. The friction between the goods and the wall of the chute can be effectively reduced, and in some environments where static electricity needs to be prevented, the electrical conductivity of the graphite particles can also eliminate static electricity, preventing damage to the goods or equipment caused by static electricity, and ensuring the safe and smooth sliding of the goods in the chute 100.

[0094] In some embodiments, the above-mentioned particulate matter can be molybdenum disulfide (MoS2) particles, which are a typical layered solid lubricant, have a very low friction coefficient, generally between 0.05 and 0.1, and can maintain good lubrication performance under high temperature, high pressure and high load conditions. Adding molybdenum disulfide particles to the inner wall of the chute 100 can form a high-efficiency lubricating layer between the goods and the wall of the chute, even in the case of heavy goods and fast sliding speed, the friction can be significantly reduced, the energy loss can be reduced, the sliding speed and trajectory of the goods can be effectively controlled, and the operating efficiency and stability of the chute 100 can be improved.

[0095] In the above, the specific coating material and particulate matter of the base layer can be appropriately selected according to actual needs, the base layer in the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 can be the same or different, and the particulate matter in the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 can be the same or different.

[0096] The chute 100 will be described in detail below in combination with the block region of each friction zone and the physical principle of the chute 100.

[0097] As an example, as shown in FIG. 1, the chute 100 can be divided into a first friction zone 1001, a second friction zone 1002 and a third friction zone 1003 according to the sliding speed of the goods. Figure 3As shown, along the extension direction a of the chute 100, the first friction area 1001 is divided into a standard transportation area S1-1, a standard transportation area S1-2, a standard transportation area S1-3, and a standard transportation area S1-4. Along the extension direction a of the chute 100, the second friction area 1002 located on the same side as the inner concave side 1004 is divided into a second density buffer area S2-1, a second density buffer area S2-2, and a second density buffer area S2-3, and the second friction area 1002 located on the same side as the outer convex side 1005 is divided into a second density buffer area S2-1', a second density buffer area S2-2', and a second density buffer area S2-3'. Along the extension direction a of the chute 100, the third friction area 1003 located on the same side as the inner concave side 1004 is divided into a third density buffer area S3-1, a third density buffer area S3-2, a third density buffer area S3-3, and a third density buffer area S3-4, and the third friction area 1003 located on the same side as the outer convex side 1005 is divided into a third density buffer area S3-1', a third density buffer area S3-2', and a third density buffer area S3-3'.

[0098] As an example, different cargos are subjected to two directional velocity components at the initial position, respectively, velocity v1 and velocity v2. Among them, v1 is approximately in the horizontal direction, and its size is about 1 m / s, which can be understood as the original forward direction of the cargo. v2 is approximately at a 90-degree angle with v1, and its size is about 1 m / s, which can be understood as the sorting direction of the cargo.

[0099] As an example, all cargos with different energy densities first pass through the standard transportation area S1-1, and the cargos with larger energy density (for example, the third energy density cargo) automatically pass through the second density buffer area S2-1 and / or the third density buffer area S3-1 (approximately the position of the first convex part 1004a) in turn and rush to the highest point, and then under the action of the reaction force, it is guided to enter the second density buffer area S2-1' and / or the third density buffer area S3-1' (approximately the part on the convex part 1005a close to the concave part 1005b) in turn, so that different friction areas have different friction coefficients to adjust the running track of the cargo. Again under the action of the reaction force, the cargo is guided to the second density buffer area S2-3 and / or the third density buffer area S3-3, the third density buffer area S3-4 again, and then sorted out from the chute 100 at the standard transportation area S1-4 after being slowed down to v3.

[0100] For example, the goods with medium energy density (e.g., the goods with the second energy density) firstly pass through the standard transportation area S1-1, and then pass through the second density buffer area S2-1 (approximately the position of the first convex part 1004a) automatically and sequentially, and are guided to the highest point under the action of the reaction force, and then are guided to enter the second density buffer area S2-1' (approximately the part on the concave part 1005b close to the convex part 1005a) under the action of the reaction force, so that the different friction areas have different friction coefficients to adjust the running track of the goods. Again under the action of the reaction force, the goods are guided to the second density buffer area S2-3 again until the speed is reduced to v3, and are sorted out from the chute 100 from the standard transportation area S1-4.

[0101] For example, the goods with small energy density (e.g., the goods with the first energy density) move in a parabolic motion in the standard transportation area S1-1, the standard transportation area S1-2, the standard transportation area S1-3, and the standard transportation area S1-4, and are sorted out from the chute 100 from the standard transportation area S1-4 at the terminal speed of v3.

[0102] In this way, the goods with different energy densities have different s-shaped motion paths and consume different energy, and finally are sorted out from the chute 100 at the standard transportation area S1-4 at a substantially consistent speed, and are safely and effectively entered into the sorting position.

[0103] wherein the gravitational potential energy Ep of the goods is mgh, the kinetic energy K is (M*V2) / 2, the friction work W is FS=mg*μs, and μs is the friction coefficient. The goods are subjected to two forces in the motion process, which are the gravity and the friction force. When the goods move downward, the gravitational potential energy is converted into the kinetic energy, and when the goods move upward, the gravitational potential energy offsets part of the kinetic energy.

[0104] The initial energy k1 of the goods is (M*V12) / 2 + (M*V22) / 2, the energy k2 of the goods in the sliding process is k1+W+mgh, and the terminal energy k3 of the goods is (M*V32) / 2. It can be deduced that w=k1-k3+mgh. Therefore, the shape of the chute 100 and the friction coefficients of different areas are properly designed according to w, so that the goods with different energy densities run on different motion paths, consume different proportions of kinetic energy, and achieve the same motion speed at the outlet position.

[0105] Based on the above first embodiment, another purpose of the embodiment of the application is to provide a goods conveying mechanism, which comprises the chute 100 as above, and a conveying belt, the conveying belt and the chute 100 are sequentially arranged along the conveying path of the goods, and the conveying end of the conveying belt and the guide inlet 100a of the chute 100 are communicatively arranged.

[0106] The second embodiment of the present application aims to provide a chute 100 suitable for goods with a second energy density of 1 / 3P1≤P<≤P1 and goods with a first energy density of P<1 / 3P1, so as to avoid the technical problems of goods stagnation, ejection from both sides in the middle, or ejection from the chute 100 at a large speed, which leads to normal sorting failure or cannot guarantee the safety of goods and sorting.

[0107] Please refer to Figures 1 to 6 The chute 100 has at least a first friction area 1001 and a second friction area 1002 in the width direction b of the chute 100 and from the center of the chute 100 to the edge of the width of the chute 100, the first friction area 1001 and the second friction area 1002 are both arranged along the extension direction a of the chute 100, and the second friction area 1002 has a friction coefficient greater than that of the first friction area 1001, the first friction area 1001 is used to limit the trajectory of the goods with the first energy density within the first friction area 1001, the second friction area 1002 is used to limit the trajectory of the goods with the second energy density within the second friction area 1002 and the first friction area 1001, and the first friction area 1001 and the second friction area 1002 are also used to make the exit speed of the goods with the first energy density and the goods with the second energy density consistent; wherein the second energy density is greater than the first energy density, and the energy density is the energy consumed by the unit volume of goods when sliding and conveying in the chute 100.

[0108] The chute 100 has a coating layer on the inner wall of the chute 100, the coating layer includes a base layer and particles doped in the base layer and having hardness; and the base layer in the first friction area 1001 and the second friction area 1002 is the same or different, the particle size of the particles in the first friction area 1001 is smaller than that of the particles in the second friction area 1002; and the pressure P1 of 1dm of liquid water is set to 980pa, the pressure P of the goods on the inner wall of the chute 100 is set, and P is positively correlated with the energy density, then: when 1 / 3P1≤P<≤P1, the goods are goods with the second energy density; when P<1 / 3P1, the goods are goods with the first energy density.

[0109] The second embodiment of the present application can be used to convey the first energy density goods and the second energy density goods through the same chute 100, the first energy density goods and the second energy density goods can be low energy goods and medium energy goods respectively, and the first energy density goods and the second energy density goods have a set pressure range. The inner wall of the chute 100 has a non-uniformly arranged friction force, which can simultaneously adapt to the conveying of the two energy goods. The non-uniformly arranged friction force limits the goods in a constrained friction zone during the sliding conveying process, and the technical problems such as the goods being thrown out from both sides or being rushed out of the chute 100 at a large speed in the middle of the conveying process, which leads to the failure of normal sorting or the failure to guarantee the safety of the goods and the safety of the sorting, do not occur. In addition, the friction zone considers the required work amount to ensure that it normally reaches the guide outlet 100b, and the goods do not stop.

[0110] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002 arranged on both sides of the first friction zone 1001 along the width direction b, and the two second friction zones 1002 are used to limit the trajectory of the second energy density goods between the two outer edges of the two second friction zones 1002 facing away from each other along the width direction b.

[0111] In some embodiments, the chute 100 has a concave side 1004 and a convex side 1005 arranged at intervals along the width direction b; in the two second friction zones 1002, the outer edge of one second friction zone 1002 and the side of the concave side 1004 on the same side are connected or arranged at intervals, and the outer edge of the other second friction zone 1002 and the side of the convex side 1005 on the same side are connected or arranged at intervals.

[0112] That is, the outer edge of the second friction zone 1002 can be spaced apart from the side of the chute 100 by a certain distance, or directly extend to the side, for example, the second friction zone 1002 can occupy the position occupied by the second friction zone 1002 in the first embodiment, or the second friction zone 1002 occupies the position occupied by the second friction zone 1002 in the first embodiment and the position occupied by the third friction zone 1003.

[0115] In some embodiments, the first convex part 1004a and the second convex part 1004b are continuously arranged or discontinuously arranged along the extension direction a, and the protruding part 1005a and the recessed part 1005b are continuously arranged along the extension direction a.

[0116] Based on the second embodiment, another purpose of the present application is to provide a goods conveying mechanism, which comprises the chute 100 as above and a conveyor belt, the conveyor belt and the chute 100 are sequentially arranged along the conveying path of the goods, and the conveying end of the conveyor belt is in communication with the inlet 100a of the chute 100.

The first protruding part 1004a is used to limit the trajectory of the third energy density goods for the first time, the part of the recessed part 1005b close to the protruding part 1005a is used to limit the trajectory of the third energy density goods for the second time, and the second protruding part 1004b is used to limit the trajectory of the third energy density goods for the third time, so that the third energy density goods are smoothly guided out of the outlet 100b.

[0125] In some embodiments, the first protruding part 1004a and the second protruding part 1004b are arranged continuously or discontinuously along the extension direction a, and the protruding part 1005a and the recessed part 1005b are arranged continuously along the extension direction a.

[0126] Based on the third embodiment, another object of the present application is to provide a goods conveying mechanism, which comprises the chute 100 as above and a conveyor belt, the conveyor belt and the chute 100 are arranged in sequence along a conveying path of the goods, and a conveying end of the conveyor belt is arranged in communication with the guide inlet 100a of the chute 100.
