Description

Technical Field

[0001] This application relates to the field of logistics technology, specifically to a conveying unit, a conveying method, and a conveying system. Background Technology

[0002] Currently, in the logistics transportation field, belts, rollers, and other methods are commonly used for the straight-line transport of packages, while swing wheels and turning belts are used to change the transport direction of packages. However, changing the transport direction of packages using swing wheels and turning belts is less flexible and increases the footprint of the equipment. At the same time, because traditional belts, rollers, and other devices achieve transport through rotation, there are large gaps at the arc-shaped joints of these devices, which can easily cause packages to get stuck, affecting package transport and even leading to package damage. Summary of the Invention

[0003] This application provides a conveying unit, a conveying method, and a conveying system, aiming to solve the technical problem of poor flexibility in changing the direction of package transportation in traditional parcel transportation devices.

[0009] In some embodiments, the conveying body is provided with multiple air supply channels;

[0010] Each air supply channel is connected to an air vent with a different airflow direction, while air vents with the same airflow direction share the same air supply channel.

[0011] In some embodiments, each pore group has the same airflow direction layout, and in each pore group, the airflow direction of each pore is different.

[0012] Multiple air supply channels are connected one-to-one with the air holes in the same air hole group, and the air holes in the same airflow direction in the multiple air hole groups are connected to the same air supply channel.

[0013] In some embodiments, multiple air hole groups are arranged in a rectangular array, wherein all air hole groups are distributed in multiple rows and / or multiple columns, and the conveying body is also provided with corresponding multiple rows and / or multiple columns of diversion channels;

[0014] Among them, one row of diversion channels is connected to the air holes in the same row of air holes in the same air flow direction, one row of diversion channels is connected to the air holes in the same row of air holes in the same air flow direction, and multiple diversion channels connected to air holes in the same air flow direction are connected to the corresponding air supply channels.

[0015] In some embodiments, multiple flow channels connecting vents in the same airflow direction are parallel to each other.

[0016] In some embodiments, the number of diversion channels, the number of multiple vents in the same vent group, the number of columns and rows of multiple vent groups arranged in a rectangular array satisfy the following relationship:

[0017] S=(ma)*x+(a)*y

[0018] Where S is the number of diversion channels, m is the number of multiple pores in the same pore group, a is the number of multiple pores in the same pore group that are connected to the row-shaped diversion channels, x is the number of columns in the multiple pore groups, and y is the number of rows in the multiple pore groups.

[0019] In some embodiments, half of the pores in the same pore group are connected to a row-shaped diversion channel, and the other half of the pores are connected to a column-shaped diversion channel.

[0020] In some embodiments, the flow dividers connecting the vents in the same airflow direction are located on the same horizontal plane;

[0021] The flow channels connecting vents in different airflow directions are located in different vertical planes or different horizontal planes.

[0022] In some embodiments, the delivery body has multiple sides, and the central axis of the air supply channel is parallel to at least one side.

[0023] In some embodiments, the conveying body is in the shape of a cuboid and has four sides;

[0024] In the same pore group, multiple pores include a first pore, a second pore, a third pore, and a fourth pore, which extend along the four sides of the central axis respectively.

[0025] In some embodiments, the delivery unit further includes at least one air supply device and multiple air supply pipelines;

[0026] Each gas supply line is connected to an air vent with a different airflow direction, and the gas supply device supplies gas to the gas supply line.

[0063] This application provides a conveying unit 100, a conveying method, and a conveying system, which will be described in detail below.

[0064] First, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 This paper shows a schematic diagram of a conveying unit 100 in an embodiment of this application. Figure 2 A perspective view of the conveying unit 100 in an embodiment of this application is shown. Figure 3 This application shows Figure 2 A magnified view of a portion of point A in the diagram. Figure 4 This illustration shows a schematic diagram of an embodiment of the present application in which the air vent 11 is disposed on the conveying body 10, wherein the conveying unit 100 has multiple conveying directions, and the conveying unit 100 includes:

[0065] The conveying body 10 is provided with multiple air hole groups 110. Each air hole group 110 includes multiple air holes 11. Each air hole 11 includes an airflow channel 1102 and an air outlet 1101.

[0066] In each group of air vents 110, multiple air vents 11 have different airflow directions based on airflow channels 1102 with different orientations. The airflow direction of any air vent 11 has a directional component along at least one conveying direction, and any conveying direction is in the same direction as the directional component of the airflow direction of at least one air vent 11.

[0067] Specifically, the conveying direction of the conveying unit 100 refers to the direction in which it transports objects. Generally, the multiple conveying directions of the conveying unit 100 are located in the horizontal plane. For example, the multiple conveying directions of the conveying unit 100 include horizontal forward, horizontal backward, horizontal left, and horizontal right directions. It can be understood that the conveying direction of the conveying unit 100 can also be at a certain angle to the horizontal plane, or the conveying direction of the conveying unit 100 can also be parallel to the surface of the conveying body 10.

[0068] The conveying body 10 is used to form the vent group 110, and the gas output from the vent group 110 drives the object to move. Generally, such as... Figure 1 As shown, multiple vent groups 110 can be arranged in a rectangular array on the surface of the conveying body 10. All vent groups 110 are distributed in multiple rows and / or columns, that is, multiple vent groups 110 are arranged in rows and columns covering the entire conveying body 10. When conveying an object, according to the target transport direction of the object, gas is output from the corresponding vent group 110 on the conveying body 10 to drive the object to move along the target transport direction. It can be understood that the vent groups 110 can also have other arrangements, such as a ring array arranged around the center of the surface of the conveying body 10.

[0069] In some embodiments of this application, the conveying body 10 can be a plate-shaped object, with the air hole group 110 formed on the plate-shaped object. Exemplarily, the shape of the plate-shaped conveying body 10 can be a rectangle, a regular hexagon, or an equilateral triangle, etc. It is understood that the shape of the conveying body 10 can also be a cylinder, a cuboid, etc.

[0070] Each group of pores 110 includes multiple pores 11, see reference. Figure 4 The vent 11 includes an airflow channel 1102 and an air outlet 1101. The air outlet 1101 is located on the surface of the conveying body 10, while the airflow channel 1102 is located inside the conveying body 10. In each vent group 110, multiple vents 11 have different airflow directions based on the airflow channels 1102 with different orientations. The airflow direction refers to the flow direction of the gas delivered from the vent 11. Generally, the airflow channel 1102 is straight, and the airflow direction is controlled by the orientation of the straight airflow channel 1102, such as... Figure 4 As shown, when the angle between the orientation of the airflow channel 1102 of the straight vent 11 and the horizontal plane is 45°, the airflow direction of the straight vent 11 is at an angle of 45° with the horizontal plane.

[0071] In some embodiments of this application, such as an embodiment where the cross-section of the vent 11 is circular, the orientation of the airflow channel 1102 of the vent 11 is parallel to its central axis. It is understood that the cross-section of the vent 11 can also be other shapes, such as square, triangle, etc., and the orientation of the vent 11 is along the center line of the square or triangular vent 11.

[0072] Understandably, the airflow channel 1102 of the vent 11 can also be curved, such as serpentine, wavy, or multi-segment straight, for example, see [reference needed]. Figure 5 , Figure 5 This illustration shows a schematic diagram of an embodiment of the present application in which the air hole 11 is provided on the conveying body 10, and the airflow direction is controlled by a portion of the airflow channel 1102 near the air outlet 1101 at the end of the air hole 11.

[0073] In some embodiments of this application, such as embodiments where the air holes 11 are straight, drilling air holes 11 with different orientations on the conveying body 10 can result in multiple air holes 11 in the same air hole group 110 having different airflow directions. In other embodiments of this application, such as embodiments where the air holes 11 are curved, controlling the orientation of the airflow channel 1102 near the air outlet 1101 at the end of the air hole 11 can result in multiple air holes 11 in the same air hole group 110 having different airflow directions.

[0074] It is worth noting that, unless otherwise specified, the plurality of pores 11 in this application refers to a group of pores 110, that is, a group of pores 11 included in a group of pores 110, and not to all pores 11 on the conveying body 10.

[0075] The directional component is obtained by decomposing an airflow direction, delivery direction, or orientation. Generally, a single airflow direction can be decomposed into two directional components. The airflow direction and the two directional components satisfy the parallelogram law. For example, the two directional components are perpendicular to each other and can be combined to form the decomposed airflow direction. As an example, the airflow direction of the vent 11 can be decomposed into a directional component in the horizontal plane and a directional component perpendicular to the horizontal plane; as another example, the movement direction can be decomposed into a directional component along the airflow direction of a vent 11 and a directional component in a plane perpendicular to the airflow direction of a vent 11.

[0076] In some embodiments of this application, such as embodiments where multiple conveying directions of the conveying unit 100 are on a horizontal plane, the airflow direction of the vent 11 forms a preset angle with the horizontal plane (or the surface of the conveying body 10), which is greater than 0° and less than 90°, so that the airflow direction of the vent 11 can be decomposed into a directional component in the horizontal plane and a directional component perpendicular to the horizontal plane. When air is released from the vent 11, the gas generates a pushing force on the object on the conveying body 10. This pushing force can be decomposed into a component force in the horizontal plane and a component force perpendicular to the horizontal plane. The component force perpendicular to the horizontal plane can at least offset part of the object's weight, reduce or even completely eliminate the friction between the object and the conveying body 10, and the component force in the horizontal plane can push the object to move, ultimately realizing the movement of the object.

[0077] In the embodiments of this application, see Figure 6 , Figure 6 A schematic diagram showing the relationship between the airflow direction and the conveying direction of the vent 11 in the embodiment of this application is shown. The airflow direction of any vent 11 has a directional component along at least one conveying direction, and the directional component of the airflow direction of any conveying direction is in the same direction as the directional component of the airflow direction of at least one vent 11. That is, any vent 11 corresponds to at least one conveying direction, and any conveying direction corresponds to at least one vent 11. The relationship between the conveying direction and the vent 11 is one-to-one or one-to-many. When the object moves along the conveying direction, one or more oblique air vents in the same vent group 110 are released at the same time.

[0078] In some embodiments of this application, the conveying direction and the air hole 11 can correspond one-to-one, for example, see [reference]. Figure 7 , Figure 7 This illustration shows a schematic diagram of multiple air holes 11 in the same air hole group 110 and multiple conveying directions in an embodiment of this application. The multiple conveying directions of the conveying unit 100 include horizontal forward, horizontal backward, horizontal left and horizontal right directions. The airflow direction of the multiple air holes 11 has horizontal forward, horizontal backward, horizontal left and horizontal right directional components, thereby driving the object to move in the horizontal forward, horizontal backward, horizontal left and horizontal right directions.

[0079] In other embodiments of this application, the relationship between the conveying direction and the air vent 11 is one-to-many, for example, see [reference needed]. Figure 8 , Figure 8 This illustration shows another schematic diagram of multiple air holes 11 and multiple conveying directions in the same air hole group 110 in an embodiment of this application. The conveying directions include eight directions: horizontal forward, horizontal backward, horizontal left, horizontal right, horizontal left front corner, horizontal right front corner, horizontal left rear corner, and horizontal right rear corner. The airflow direction of the multiple air holes 11 has directional components of horizontal forward, horizontal backward, horizontal left, and horizontal right, respectively.

[0080] In the above embodiment, when the object needs to move horizontally to the left front corner, the air vents 11 with horizontal forward and horizontal left components simultaneously release air. The object is subjected to a thrust in the horizontal forward and horizontal left directions, and the thrusts combine to form a resultant force in the direction of the left front corner of the conveying body 10, thereby propelling the object to move towards the left front corner of the conveying body 10. Similarly, when the object moves horizontally to the right front corner, the air vents 11 with horizontal forward and horizontal right components simultaneously release air. The same principle applies when the object needs to move horizontally to the left rear corner and horizontally to the right rear corner, which will not be elaborated further here.

[0081] Understandably, this application can also have a greater number of delivery directions, for example, see [reference needed]. Figure 9 , Figure 9 This illustration shows another schematic diagram of multiple air holes 11 and multiple conveying directions in the same air hole group 110 in an embodiment of this application. There are 16 conveying directions arranged in a ring array in the horizontal plane around the center of the conveying body 10. By controlling the flow rate of gas from multiple air holes 11, the magnitude of the thrust of gas from a single air hole 11 on the object is changed, thereby changing the direction of the resultant force and the direction of movement of the object.

[0082] As an exemplary embodiment of the arrangement of multiple pores 11 in the pore group 110, see [reference]. Figure 10 as well as Figure 11 , Figure 10 This illustration shows a perspective view of an embodiment of the present application showing the vent assembly 110 disposed on the conveying body 10. Figure 11 This illustration shows a schematic diagram of an air vent group 110 disposed on a conveying body 10 in an embodiment of this application. The air outlets 1101 of multiple air vents 11 in the same air vent group 110 are arranged in a row. In the direction from left to right, the airflow direction of the first air vent 11 has a horizontal rightward component, the airflow direction of the second air vent 11 has a horizontal backward component, the airflow direction of the third air vent 11 has a horizontal forward component, and the airflow direction of the fourth air vent 11 has a horizontal leftward component. When it is necessary to control the movement of the object, gas can be input into the corresponding air vent 11.

[0083] As an exemplary embodiment of another arrangement of multiple pores 11 in the pore group 110, see [reference]. Figure 12 as well as Figure 13 , Figure 12 This illustration shows another perspective view of the vent assembly 110 disposed on the conveying body 10 in an embodiment of this application. Figure 13This illustration shows another schematic diagram of the vent group 110 disposed on the conveying body 10 in an embodiment of this application. Each vent group 110 includes four vents 11, and the outlets 1101 of the four vents 11 are arranged in a matrix of two rows and two columns. The airflow direction of the first vent 11 in the first row has a horizontal backward direction component, the airflow direction of the second vent 11 in the first row has a horizontal left direction component, the airflow direction of the first vent 11 in the second row has a horizontal right direction component, and the airflow direction of the second vent 11 in the second row has a horizontal forward direction component.

[0084] It is understandable that the multiple pores 11 in the pore group 110 can also have other arrangements, such as the pores 11 in the same pore group 110 being arranged in a ring, a triangle, or a regular polygon.

[0085] This application provides multiple air hole groups 110 on the surface of the conveying body 10, and each air hole group 110 is configured to include multiple air holes 11 with different airflow directions. Since the airflow direction of any air hole 11 has a directional component along at least one conveying direction, and any conveying direction has a directional component along the airflow direction of at least one air hole 11, when conveying items, air can be released from the air holes 11 in the same airflow direction or multiple airflow directions in the multiple air hole groups 110, thereby allowing items to be conveyed along multiple conveying directions. Compared with traditional methods of changing the direction of package transportation by means of swing wheels, turning belts, etc., this application has the advantages of high flexibility, low equipment manufacturing cost, and small footprint. At the same time, multiple conveying units 100 can be closely spliced ​​together to form a conveying system, avoiding large gaps between the conveying devices, thereby preventing packages from getting stuck in the gaps and affecting package transportation or even causing package damage.

[0086] Furthermore, when multiple vents 11 in the same vent group 110 emit air simultaneously, in order to concentrate the thrust on the object and make the object's movement more stable, further reference is made to some embodiments of this application. Figure 15 as well as Figure 16 , Figure 15 This illustration shows another perspective view of the vent assembly 110 disposed on the conveying body 10 in an embodiment of this application. Figure 16 This illustration shows another schematic diagram of the vent group 110 disposed on the conveying body 10 in an embodiment of this application, wherein in each vent group 110, the air outlets 1101 of all the vents 11 converge at the same point on the surface of the conveying body 10 to form a common air outlet 120.

[0087] In the above embodiment, when multiple vents 11 in the same vent group 110 simultaneously emit air, since the outlets 1101 of the multiple vents 11 converge at the same point on the surface of the conveying body 10, the gas from each vent 11 converges at the common outlet 120 to form a stream of air directed in one direction. For example, if a vent 11 with a horizontal forward airflow component and a vent 11 with a horizontal leftward airflow component simultaneously emit air, the gas from these two vents 11 converges to form a stream of air directed towards the left front corner. In other words, the movement of the object is driven by the stream of air generated by each vent group 110, relative to... Figures 9 to 13 When the air outlets 1101 of the air holes 11 in the same air hole group 110 with different airflow directions do not converge at the same point on the surface of the conveying body 10, the thrust on the object is concentrated and stable, which is beneficial to improving the stability of the object's movement when multiple air holes 11 in the same air hole group 110 emit air at the same time.

[0088] For more details, please refer to [link / reference]. Figure 17 , Figure 17 This illustration shows another perspective view of the vent group 110 disposed on the conveying body 10 in an embodiment of this application. In some embodiments of this application, in each vent group 110, the central axes of the airflow channels 1102 of each vent 11 intersect at the same point on the surface of the conveying body 10. This point is located on the plane where the common air outlet 120 is located. For embodiments where the surface of the conveying body 10 is planar, the plane where the common air outlet 120 is located is also the surface of the conveying body 10. This allows the air outlets 1101 of multiple vents 11 to overlap to the maximum extent at the same point on the surface of the conveying body 10, thereby improving the concentration of gas convergence when multiple vents 11 in the same vent group 110 emit gas simultaneously.

[0089] In some embodiments of this application, to facilitate air supply to the air holes 11 with different airflow directions, see [reference needed]. Figure 3 The conveying body 10 has multiple air supply channels 12 inside, and each air supply channel 12 is connected to an air hole 11 with different airflow directions. Air holes 11 with the same airflow direction share the same air supply channel 12.

[0090] In the above embodiment, when the air supply channel 12 supplies air, the air holes 11 connected to it in the same airflow direction simultaneously output gas. The object is pushed by the gas output from the air holes 11 in the same airflow direction, thereby moving the object. By supplying air to the air holes 11 in the same airflow direction in the multiple air hole groups 110 through the air supply channel 12, the side of the object facing the conveying body 10 can be subjected to a uniform force, ensuring the synchronicity of the air output from the air holes 11 in the same airflow direction in the multiple air hole groups 110, thereby improving the stability of the object's movement.

[0091] In some embodiments of this application, each vent group 110 has the same airflow direction layout, and in each vent group 110, the airflow direction of each vent 11 is different, such as... Figures 9 to 12 As shown, each vent group 110 has the same number of vents 11 and the same airflow direction corresponding to the vents 11. For example, each vent group 110 includes four vents 11 with airflow directions of horizontal left, horizontal right, horizontal backward and horizontal forward, so that when each vent group 110 outputs gas, each vent group 110 provides the object with a horizontal left, horizontal right, horizontal backward and horizontal forward driving force, and at the same time propels the object to move.

[0092] Understandably, additional pores can be added to some pore groups 110, for example, see [reference needed]. Figure 14 , Figure 14 This illustration shows another perspective view of the vent group 110 disposed on the conveying body 10 in an embodiment of this application. One of the vent groups 110 also has a vent 11 with the airflow direction vertically upward. The vent 11 outputs vertically upward gas to provide support for the object. Alternatively, two or more vents 11 with the same airflow direction can be provided in the same vent group 110. For example, in addition to four vents 11 with horizontal left, horizontal right, horizontal backward and horizontal forward directional components, there is an additional vent 11 with a horizontal right directional component.

[0093] In some embodiments of this application, the air supply channel 12 corresponds one-to-one with the air holes 11 of the same air hole group 110, and the air holes 11 in the same airflow direction in multiple air hole groups 110 are connected to the same air supply channel 12. For example, in the embodiment of four air holes 11 with horizontal left, horizontal right, horizontal backward and horizontal forward airflow directions, the conveying body 10 is provided with four air supply channels 12. Each air supply channel 12 provides gas to an air hole 11 in a separate airflow direction, thereby ensuring the independence of air supply to the air holes 11 in the same airflow direction in multiple air hole groups 110.

[0094] As an exemplary embodiment of the arrangement of the vent group 110 and the connection between the vent 11 and the air supply channel 12, see the following... Figure 2 , Figure 3 as well as Figure 18 , Figure 18This illustration shows a schematic diagram of the connection between the air vents 11, the diversion channel 13, and the air supply channel 12 in an embodiment of this application. In this embodiment, multiple air vent groups 110 are arranged in a rectangular array, and all air vent groups 110 are distributed in multiple rows and / or multiple columns. The conveying body 10 is also provided with corresponding multiple rows and / or multiple columns of diversion channels 13. One column of diversion channels 13 is connected to the air vents 11 in the same column of air vent groups 110 with the same airflow direction, and one row of diversion channels 13 is connected to the air vents 11 in the same row of air vent groups 110 with the same airflow direction. In other words, multiple air vent groups 110 are arranged in a multi-row, multi-column matrix. In each row of air vent groups 110, the air vents 11 in the same airflow direction are connected to the corresponding row of diversion channels 13. In each column of air vent groups 110, the air vents 11 in the same airflow direction are connected to the corresponding row of diversion channels 13. This allows one row or one column of diversion channels 13 to supply air to the air vents 11 in the same airflow direction. In this case, the arrangement of diversion channels 13 is adapted to the air vent groups 110 in the matrix, which can make reasonable use of the internal space of the conveying body 10 and supply air to the rectangular array of air vent groups 110.

[0095] In the above embodiment, multiple diversion channels 13 that connect the air holes 11 in the same airflow direction are connected to the corresponding air supply channels 12. When the air supply channel 12 supplies air, the gas is diverted to multiple rows and / or multiple columns of diversion channels 13, and then the gas flows to the air hole group 110 of the array of the conveying body 10. By realizing simultaneous air passage to the air holes 11 of the array, the synchronicity of air outlet of the air holes 11 in the same airflow direction on the entire surface of the conveying body 10 can be improved.

[0096] Understandably, the multiple pore groups 110 can also have other arrangements, for example, see [reference needed]. Figure 19 , Figure 19 An exemplary diagram is shown in which multiple air hole groups 110 are arranged on the conveying body 10 in an embodiment of this application. The air hole groups 110 are arranged in a ring array on the conveying body 10; or the diversion channel 13 may have other arrangements, such as being arranged diagonally on the conveying body 10.

[0097] As a preferred embodiment, in some embodiments of this application, for example, where multiple air vent groups 110 are arranged in a rectangular array, and the conveying body 10 is further provided with multiple rows and / or columns of diversion channels 13, see further details. Figure 2 as well as Figure 3 Multiple diversion channels 13 connected to the air holes 11 in the same airflow direction are parallel to each other, avoiding the multiple diversion channels 13 connected to the air holes 11 in the same airflow direction from intersecting each other, thereby avoiding complicating the channel structure inside the conveying body 10, and also reducing the processing difficulty of the internal channels (such as diversion channels 13 and air supply channels 12) of the conveying body 10.

[0098] In some embodiments of this application, the number of diversion channels 13, the number of multiple vents 11 in the same vent group 110, the number of columns and rows of multiple vent groups 110 arranged in a rectangular array satisfy the following relationship:

[0099] S=(ma)*x+(a)*y

[0100] Where S is the number of diversion channels 13, m is the number of multiple vents 11 in the same vent group 110, a is the number of multiple vents 11 in the same vent group 110 that are connected to the row-shaped diversion channels 13, x is the number of columns of the multiple vent groups 110 arranged in a rectangular array, and y is the number of rows of the multiple vent groups 110 arranged in a rectangular array.

[0101] As an example, when a = 0, that is, there is no row-shaped diversion channel 13, and the air holes 11 with different airflow directions are all connected to the column-shaped diversion channel 13. In this embodiment, the number of diversion channels 13 is the product of the number of multiple air holes 11 and the number of columns of multiple air hole groups 110 arranged in a rectangular array.

[0102] As another example, when a = m, that is, there is no column-shaped diversion channel 13, and the air holes 11 with different airflow directions are all connected to the row-shaped diversion channel 13. In this embodiment, the number of diversion channels 13 is the product of the number of multiple air holes 11 and the number of rows of multiple air hole groups 110 arranged in a rectangular array.

[0103] In a preferred embodiment, when a = m / 2, half of the multiple air holes 11 are connected to the row-shaped diversion channels 13, while the other half are connected to the column-shaped diversion channels 13. This allows the row-shaped and column-shaped diversion channels 13 to be reasonably arranged in different horizontal and vertical planes, thus making reasonable use of the internal space of the conveying body 10. This avoids the phenomenon that the row-shaped or column-shaped diversion channels 13 need to be arranged in layers on different horizontal planes, which would result in the conveying body 10 being too thick.

[0104] For further details, please refer to [link / reference]. Figure 2 as well as Figure 3 In this configuration, the branch channels 13 connecting the air holes 11 with the same airflow direction are located on the same horizontal plane. At this time, the air supply channel 12 corresponding to the air hole 11 with the same airflow direction is also within this horizontal plane. That is, the air supply channel 12 is a straight channel, which helps reduce the processing difficulty of the air supply channel 12. Simultaneously, the branch channels 13 connecting the air holes 11 with different airflow directions are located on different vertical planes or different horizontal planes, which can prevent the branch channels 13 connecting the air holes 11 with different airflow directions from being interconnected, ensuring the independence of the air supply to the air holes 11 with different airflow directions. It is understandable that the branch channels 13 connecting the air holes 11 with the same airflow direction can also be located within the same vertical plane.

[0105] In some embodiments of this application, see Figure 17 The conveying body 10 has multiple sides 130. The central axis of the air supply channel 12 is parallel to at least one side 130. Generally, the distance between the central axis and the adjacent side 130 is greater than the radius of the air supply channel 12 but less than the diameter of the air supply channel 12. This allows the air supply channel 12 to be located close to the side 130 of the conveying body 10, which is beneficial for the air supply channel 12 to connect to the air supply equipment outside the conveying body 10. At the same time, the air supply channel 12 and the diversion channel 13 are reasonably arranged at the edge and middle of the conveying body 10, respectively, to avoid the air supply channel 12 from intersecting with multiple rows or columns of diversion channels 13 and causing complexity in the internal structure of the conveying body 10.

[0106] For one specific implementation method, please refer to [link / reference]. Figure 2 , Figure 3 , Figure 6 as well as Figure 17 The conveying body 10 is rectangular in shape and has four sides 130. In the same group of air holes 110, a plurality of air holes 11 include a first air hole 111, a second air hole 112, a third air hole 113 and a fourth air hole 114, whose central axis extends along the four sides 130 of the conveying body 10 respectively.

[0107] In the above embodiments, when only the first air hole 111, the second air hole 112, the third air hole 113, or the fourth air hole 114 emits air, the moving unit can control the object to move to the rear, right, front, or left of the conveying body 10, respectively; when two of the first air hole 111, the second air hole 112, the third air hole 113, or the fourth air hole 114 emit air at the same time, the moving unit can control the object to move to a corner of the conveying body 10. For example, when the first air hole 111 and the second air hole 112 emit air at the same time, the moving unit can control the object to move to the upper left corner of the conveying body 10.

[0108] It is understandable that when air is emitted from the first vent 111, the second vent 112, the third vent 113, or the fourth vent 114 at the same time, the direction of movement of the object can be changed by changing the gas flow rate of the two vents 11, thus achieving multi-directional adjustment of the direction of movement of the object.

[0109] Furthermore, for the purpose of venting pore 11, please refer to [further details]. Figure 20 , Figure 20The diagram illustrates another structural embodiment of the conveying unit 100 in this application. The conveying unit 100 further includes at least one air supply device 20 and multiple air supply pipes 30. Each air supply pipe 30 is connected to an air hole 11 with a different airflow direction. The air supply device 20 supplies air to the air supply pipes 30. For example, the air supply device 20 can be a blower, air compressor, or air pump, or other gas conveying equipment.

[0110] Generally, in order to ensure the independence of air supply to each vent 11, the number of air supply devices 20 and air supply pipes 30 corresponds to the number of vents 11. For example, in the above embodiment including the first vent 111, the second vent 112, the third vent 113 and the fourth vent 114, the number of air supply devices 20 and air supply pipes 30 are four, so as to supply air to the first vent 111, the second vent 112, the third vent 113 and the fourth vent 114 respectively.

[0111] In some embodiments of this application, such as the embodiment in which the conveying body 10 is provided with an air supply channel 12 and a diversion channel 13, one end of the air supply pipe 30 is connected to the air supply device 20 and the other end is connected to the air supply channel 12. The gas output by the air supply device 20 flows through the air supply pipe 30 into the air supply channel 12, and then flows through the diversion channel 13 into the air hole 11. Finally, the gas is output through the air hole 11 and pushes the object to move.

[0112] Understandably, the gas supply device 20 can also supply gas directly to the gas port 11 through multiple gas supply lines 30; or multiple gas supply lines 30 can be connected to the same gas supply device 20.

[0113] Furthermore, to facilitate control of the gas flow rate of the vents 11 in different airflow directions, please refer to [further details]. Figure 20 The conveying unit 100 also includes multiple flow control valves 40, each corresponding to a gas supply pipeline 30. The flow control valves 40 are installed on the gas supply pipeline 30. By adjusting the flow rate of the air holes 11 with different airflow directions, the flow ratio of multiple air holes 11 with different airflow directions can be controlled when they emit gas at the same time, thereby controlling the magnitude and direction of the gas pushing force on the object, and ultimately achieving the purpose of adjusting the direction of the object's movement.

[0114] It is worth noting that the above description of the conveying unit 100 is intended to clearly illustrate the implementation process of this application. Under the guidance of this application, those skilled in the art can also make equivalent modifications. For example, an air supply channel 12 can be set to simultaneously connect two or more air holes 11 in multiple air hole groups 110, thereby supplying air to two or more air holes 11 in two or more air flow directions in the air hole group 110 at the same time, ensuring the synchronicity of air outlet of the air holes 11 when air supply from two or more air flow directions is required.

[0115] Furthermore, to better implement the conveying unit 100 in the embodiments of this application, based on the conveying unit 100, the embodiments of this application also provide a conveying method, which is applied to the conveying unit 100 in any of the above embodiments, and the conveying method includes:

[0116] The object is placed on the conveying unit 100, and the object at least covers part of the pore group 110 on the surface of the conveying body 10;

[0117] According to the preset moving direction of the object, control the air outlet of at least one air hole 11 in the airflow direction of the multiple air hole groups 110 on the surface of the conveying body 10.

[0118] Specifically, the preset movement direction of an object (e.g., a thin package) refers to the direction in which it will move, such as forward, backward, left, or right. In some embodiments of this application, when the preset movement direction of the object is in the same direction as the directional component of the airflow direction of one vent 11, air can be vented only through that vent 11, and the object can move under the propulsion of the gas. In some embodiments of this application, when the preset movement direction of the object coincides with the vector sum of the directional components of the airflow directions of two vents 11 (e.g., the vector sum of the directional components of the airflow directions of two vents 11 in the horizontal plane), the object can move through both vents 11. Similarly, when the preset movement direction of the object coincides with the vector sum of the directional components of the airflow directions of more than two vents 11, air is vented through all of the more than two vents 11.

[0119] In some embodiments of this application, when controlling the air outlet 11 on the surface of the conveying body 10, the airflow direction of the air outlet 11 can be compared with a preset movement direction in advance. For example, the direction component of the airflow direction of the air outlet 11 in the horizontal plane can be compared with the preset movement direction. If the direction component of the airflow direction of the air outlet 11 in the horizontal plane coincides with the preset movement direction, it means that the air outlet of a single air outlet 11 can meet the movement requirements of the object. For example, the preset movement direction of the object is horizontal to the left, and the airflow direction of one of the air outlets 11 can be decomposed into a horizontal leftward direction and a direction component perpendicular to the horizontal plane. Then, air can be supplied to the air outlet 11 in the airflow direction to meet the movement requirements of the object.

[0120] In other embodiments of this application, such as embodiments where the movement of an object requires controlling the simultaneous air output of two vents 11, the step of controlling the air output of at least one vent 11 in the airflow direction of a plurality of vent groups 110 on the surface of the conveying body 10 according to the preset movement direction of the object includes: controlling the air output flow rate of the two vents 11 so that the vector sum of the air output from the two vents 11 is along the preset movement direction in the horizontal plane.

[0121] In the above embodiment, since the air flow rate of the two vents 11 is controlled, the air output from the two vents 11 becomes a vector with magnitude and direction. This allows the vector sum of the air output from the two vents 11 to have its component in the horizontal plane along a preset direction of movement. The component of this vector sum perpendicular to the horizontal plane corresponds to the gravity of the object. In other words, by adjusting the air flow rate of the two vents 11, the magnitude and direction of the force exerted by the gas on the object are controlled. The component of this force in the horizontal plane is in the same direction as the preset direction of movement, while the component perpendicular to the horizontal plane cancels out the gravity of the object.

[0122] Specifically, the air outlet 11 and the air flow rate of the air outlet 11 can be calculated by back-calculation based on the preset movement direction. For example, the directional components of the two air outlets 11 in the horizontal plane are along the X-axis and Y-axis respectively. The angle between the preset movement direction and the X-axis and Y-axis is determined, and then the air flow rate of the two air outlets 11 can be calculated using the cosine formula.

[0123] Understandably, it is also possible to control multiple vents 11 to emit air simultaneously and their airflow rates, with the vector sum of the air emitted from these multiple vents 11 and its component in the horizontal plane moving along a preset direction.

[0124] Furthermore, to better implement the conveying unit 100 in the embodiments of this application, a conveying system is also provided in the embodiments of this application based on the conveying unit 100, see reference. Figure 21 , Figure 21 A schematic diagram of a conveying system according to an embodiment of this application is shown. The conveying system includes a plurality of conveying units 100 of any of the above embodiments.

[0125] In some embodiments of this application, multiple conveying units 100 are mounted on a frame 200, and an image sensor 300 is provided on the frame 200. The image sensor 300 can acquire images of the objects wrapped on the conveying units 100, thereby determining the position of the objects. After determining the position of the objects and the target position, the preset direction of movement of the objects can be determined.

[0126] In some embodiments of this application, multiple conveying units 100 are laid out on the same plane and form at least one discharge port 400. For express delivery sorting, express packages can move freely in the plane and be sorted through the discharge port 400. At the same time, due to the multi-directional conveying characteristics of the conveying units 100, express packages can not only move to the conveying units 100 in the front, back, left, and right directions, but also move directly to the conveying unit 100 at the opposite corner, thereby shortening the movement path of express packages and providing flexibility in the movement of express packages.

[0127] It is understood that the multiple conveying units 100 in the conveying system of this application may also have other arrangements, such as forming a linear, ring-shaped or other irregularly shaped conveying system.

[0128] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the detailed descriptions of other embodiments above, which will not be repeated here.
