Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and in particular to a transport platform and sorting device. Background Technology

[0002] Currently, sorting devices are commonly used to sort goods during logistics transportation. After the goods to be sorted are transported to the sorting device, they move along the device driven by a conveyor belt. As the goods pass through the sorting chutes near the conveyor belt, different types of goods sequentially enter different sorting chutes and slide into their target positions under the guidance of the chutes, thus achieving the sorting of the goods.

[0003] However, goods are typically packaged in rough-surfaced bags such as woven bags during transportation. When goods enter the sorting chute, the large contact area between the woven bag and the chute results in significant friction. Furthermore, multiple goods may be packed within the same woven bag, leading to uneven distribution of force and hindering the smooth descent of goods along the chute. Limited by the chute's capacity, multiple goods entering simultaneously can easily cause packing problems. Summary of the Invention

[0004] The purpose of this invention is to provide a transport platform and sorting device to improve the problem of goods having difficulty sliding down the sorting chute. The specific technical solution is as follows:

[0005] This application provides a transportation platform, including:

[0006] A transport frame, including a conveyor belt, on which a swing wheel mechanism is provided;

[0007] Sorting chutes are disposed on both sides of the conveyor belt. The inlet of the sorting chutes is located on the side of the sorting chutes closer to the conveyor belt and is connected to the swing wheel mechanism on the conveyor belt. The sorting chutes include a bottom wall and a first side wall. The projection of the bottom wall onto the horizontal plane extends in a direction parallel to the extension direction of the conveyor belt. The bottom wall includes a first contact surface and a second contact surface. The first contact surface is a plane, and the second contact surface connects the first contact surface and the first side wall. The first end of the bottom wall is higher than the second end. The first side wall connects the inlet of the sorting chutes to the side of the bottom wall closer to the conveyor belt, and the first side wall is a curved surface.

[0008] In some embodiments of this application, the number of conveyor belts is one;

[0009] The sorting chute is a single-sided chute, and the single-sided chute is provided on both sides of the conveyor belt. The single-sided chute includes a bottom wall, a first side wall and a second side wall. The second side wall protrudes from the bottom wall and surrounds the first end of the bottom wall and the side of the bottom wall away from the conveyor belt.

[0010] In some embodiments of this application, the number of conveyor belts is multiple, and the multiple conveyor belts are arranged in parallel and at intervals;

[0011] The sorting chute includes:

[0012] A single-sided chute is provided on the side of the conveyor belt that is not adjacent to any other conveyor belt. The single-sided chute includes a bottom wall, a first side wall, and a second side wall. The second side wall protrudes from the bottom wall and surrounds a first end of the bottom wall and the side of the bottom wall away from the conveyor belt.

[0013] A double-sided chute is disposed between two adjacent conveyor belts. The double-sided chute has two inlets, located on the sides of the two adjacent conveyor belts that are close to each other, and connected to the swing wheel mechanisms on the two conveyor belts respectively. The double-sided chute includes a bottom wall and two first side walls. The two first side walls are respectively connected to different inlets of the sorting chute and the side of the bottom wall close to the inlet. The bottom wall includes a first contact surface and two second contact surfaces. The two second contact surfaces are respectively connected to the first contact surface and different first side walls.

[0014] In some embodiments of this application, the ratio between the center distance between two adjacent conveyor belts and the width of the bottom wall of the double-sided chute ranges from 25:2 to 45:4.

[0015] In some embodiments of this application, the number of sorting chutes is multiple;

[0016] The sorting chute is partially arranged in a forward direction, and the first end to the second end of the bottom wall of the forward-arranged sorting chute is in the same direction as the movement direction of the conveyor belt in the horizontal plane.

[0017] Another part of the sorting chute is arranged in reverse, and the first to second ends of the bottom wall of the reverse-arranged sorting chute are in the opposite direction of the movement of the conveyor belt in the horizontal plane.

[0018] In some embodiments of this application, the angle between the projection of the first sidewall of the sorting chute arranged in the forward direction and the direction of movement of the conveyor belt on the horizontal plane is 50°±2°.

[0019] In some embodiments of this application, the transport platform further includes: at least one set of conveyor belts, each set of conveyor belts including a first conveyor belt and a second conveyor belt; at least one set of sorting chutes is provided between the first conveyor belt and the second conveyor belt in the same set; each set of sorting chutes includes sorting chutes arranged in a forward direction and sorting chutes arranged in a reverse direction, and the sorting chutes arranged in the same set in a forward direction and the sorting chutes arranged in a reverse direction are arranged opposite to each other in sequence along the movement direction of the conveyor belt;

[0020] The first conveyor belt is connected to the outlet of the sorting chute arranged in the forward direction;

[0021] The second belt conveyor is connected to the outlet of the sorting chute, which is arranged in the opposite direction;

[0022] The minimum distance between the first and second belt conveyors in the same group on the horizontal plane is 5800mm.

[0023] In some embodiments of this application, the goods on the conveyor belt enter the balance wheel mechanism from the first end of the balance wheel mechanism;

[0024] The number of sorting chutes is multiple;

[0025] The outlet of one portion of the sorting chute is located above the outlet of the other portion of the sorting chute;

[0026] The first interval between the inlet of the sorting chute located below the outlet and the first end of the balance wheel mechanism is 200mm ± 5mm;

[0027] The second interval between the inlet of the sorting chute located above the outlet and the first end of the balance wheel mechanism is 50mm ± 5mm.

[0028] In some embodiments of this application, the first sidewall is a diamond facet, and the bottom wall is made of flat sheet metal.

[0029] This application also provides a sorting device, including the transport platform described in any of the above embodiments.

[0030] Beneficial effects of the embodiments of the present invention:

[0031] This invention provides a transport platform and sorting device in which the first contact surface of the bottom wall of the sorting chute is set as a plane. Compared with the curved shape of the first side wall, the plane first contact surface extends horizontally in the width direction, resulting in a larger internal space for the sorting chute and improving the problem of crowding when multiple goods enter the sorting chute simultaneously. When goods enter from the inlet of the sorting chute, they slide towards the first contact surface of the bottom wall under the guidance of the first side wall. Thus, within the sorting chute, part of the goods contacts the curved first side wall, and another part contacts the bottom wall. Because the first contact surface of the bottom wall is plane, it prevents the goods from converging towards the center of the sorting chute and thus squeezing the side walls of the goods. This effectively reduces the contact area between the goods and the sorting chute, thereby reducing the friction between the sorting chute and the goods that hinders their descent.

[0032] Of course, implementing any product or method of the present invention does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of the present invention.

[0053] This application provides a transportation platform, such as Figure 1 As shown, Figure 1This is a schematic diagram of the structure of the transportation platform provided in this application. The transportation platform includes: a transportation frame 1, including a conveyor belt 11, on which a swing wheel mechanism 111 is provided; a sorting chute 2, disposed on both sides of the conveyor belt 11, with the entrance of the sorting chute 2 located on the side of the sorting chute 2 closest to the conveyor belt 11 and connected to the swing wheel mechanism 111 on the conveyor belt 11; the sorting chute 2 includes a bottom wall 21 and a first side wall 22, the projection of the bottom wall 21 on the horizontal plane extending in a direction parallel to the extension direction of the conveyor belt 11, the bottom wall 21 including a first contact surface 211 and a second contact surface 212, the first contact surface 211 being a plane, the second contact surface 212 connecting the first contact surface 211 and the first side wall 22, the first end of the bottom wall 21 being higher than the second end, the first side wall 22 connecting the entrance of the sorting chute 2 and the side of the bottom wall 21 closest to the conveyor belt 11, and the first side wall 22 being a curved surface.

[0054] In this embodiment, after the goods to be sorted are transported to the transport platform, they move along the conveyor belt 11 under the drive of the conveyor belt 11. When the goods are transported to the designated position, they enter the sorting chute 2 under the drive of the swing wheel mechanism 111. The goods are transported to the target position under the guidance of the sorting chute 2, thereby realizing the sorting of goods. The target position refers to the position to be reached after the goods are sorted. That is to say, the outlet of the sorting chute 2 is close to the target position so that the goods can reach the target position when they slide out of the outlet of the sorting chute 2.

[0055] This application sets the first contact surface 211 of the bottom wall 21 of the sorting chute 2 as a plane. Compared to the curved shape of the first side wall 22, the plane first contact surface extends horizontally in the width direction, resulting in a larger internal space for the sorting chute 2 and improving the problem of crowding when multiple goods enter the sorting chute 2 simultaneously. When goods enter from the entrance of the sorting chute 2, the first side wall 22 is a downward-protruding curved surface, and the goods slide towards the first contact surface 211 of the bottom wall 21 under the guidance of the first side wall 22. Thus, within the sorting chute 2, part of the goods contacts the curved first side wall 22, and another part contacts the bottom wall 21. Since the first contact surface 211 of the bottom wall 21 is a plane, it does not cause the goods to gather towards the center of the sorting chute 2, thereby squeezing the side wall of the goods. This effectively reduces the contact area between the goods and the sorting chute 2, thereby reducing the friction between the sorting chute 2 and the goods and its resistance to the downward movement of the goods.

[0056] In some embodiments of this application, the number of conveyor belts 11 is one; the sorting chute 2 is a single-sided chute 24, and single-sided chute 24 is provided on both sides of the conveyor belt 11, such as... Figure 1 As shown, the single-sided chute 24 includes a bottom wall 21, a first side wall 22 and a second side wall 23. The second side wall 23 protrudes from the bottom wall 21 and surrounds the first end of the bottom wall 21 and the side of the bottom wall 21 away from the conveyor belt 11.

[0057] In this embodiment, when there is only one conveyor belt 11, a single-sided chute 24 is provided on both sides of the conveyor belt 11 along the transport direction. The second sidewall 23 of the single-sided chute 24 protrudes upward from the side of the bottom wall 21 away from the first sidewall 22. When the goods enter the sorting chute 2 from the conveyor belt 11, they will slide away from the first sidewall 22 due to inertia. When the goods slide to the edge of the bottom wall 21 away from the first sidewall 22, the second sidewall 23 can block the goods, thereby restricting the movement range of the goods within the single-sided chute 24 to prevent the goods from falling out of the single-sided chute 24. When the goods are in the single-sided chute 24, part of them are in contact with the first sidewall 22 and part of them are in contact with the bottom wall 21. Since the bottom wall 21 of the single-sided chute 24 is flat, the internal space of the single-sided chute 24 is relatively large, which will not cause the goods to be gathered towards the center of the single-sided chute 24 and thus squeeze the side wall of the goods. This effectively reduces the contact area between the goods and the single-sided chute 24, thereby reducing the friction between the single-sided chute 24 and the goods and the resistance to the downward movement of the goods.

[0058] In some implementations of this application, such as Figure 1 As shown, there are multiple conveyor belts 11, which are arranged parallel to each other and spaced apart. The sorting chute 2 includes: a single-sided chute 24, located on the side of a conveyor belt 11 that is not adjacent to another conveyor belt 11, the single-sided chute 24 including a bottom wall 21, a first side wall 22 and a second side wall 23, the second side wall 23 protruding from the bottom wall 21 and surrounding the first end of the bottom wall 21 and the side of the bottom wall 21 away from the conveyor belt 11; and a double-sided chute 25, located between two adjacent conveyor belts 11. It has two inlets, located on the side of two adjacent conveyor belts 11 that are close to each other, and connected to the swing wheel mechanism 111 on the two conveyor belts 11 respectively. The double-sided chute 25 includes a bottom wall 21 and two first side walls 22. The two first side walls 22 are respectively connected to different inlets of the sorting chute 2 and the side of the bottom wall 21 that is close to the inlet. The bottom wall 21 includes a first contact surface 211 and two second contact surfaces 212. The two second contact surfaces 212 are respectively connected to the first contact surface 211 and different first side walls 22.

[0059] In this embodiment, the single-sided chute 24 is located on the side of the conveyor belt 11 that is not adjacent to other conveyor belts 11. As described in the previous embodiment, the second sidewall 23 of the single-sided chute 24 can block the goods, restricting the movement range of the goods within the single-sided chute 24 to prevent the goods from detaching from the single-sided chute 24. The technical effect of the bottom wall 21 of the single-sided chute 24 is the same as in the previous embodiment, and will not be described in detail here.

[0060] A double-sided chute 25 is provided between two adjacent conveyor belts 11, and the two inlets of the double-sided chute 25 are respectively connected to two swing wheel mechanisms 111 on the two adjacent conveyor belts 11. In this way, the goods on both sides of the double-sided chute 25 can slide into the double-sided chute 25. The two sides of the double-sided chute 25 closest to the two adjacent conveyor belts 11 are first sidewalls 22, and a flat bottom wall 21 is provided between the two first sidewalls 22. In this way, when the goods slide into the double-sided chute 25, under the guidance of the first sidewalls 22 with downward convex curved surfaces on both sides, they will eventually slide to the middle position of the double-sided chute 25, that is, slide to the top of the bottom wall 21. Since the first contact surface 211 of the bottom wall 21 is flat, it will not pull the goods towards the center of the double-sided chute 25 and squeeze the sidewalls of the goods, effectively reducing the contact area between the goods and the double-sided chute 25, thereby reducing the friction between the double-sided chute 25 and the goods and the resistance to the sliding of the goods.

[0061] In some implementations of this application, such as Figure 2 and Figure 3a As shown, Figure 2 A schematic diagram of the sorting device provided in this application; Figure 3a for Figure 2 The sorting device shown is a top view. The ratio between the center distance L1 between two adjacent conveyor belts 11 and the width D of the bottom wall 21 of the double-sided chute 25 ranges from 25:2 to 45:4.

[0062] In this embodiment, when there are multiple conveyor belts 11, and the multiple conveyor belts 11 are arranged in parallel and spaced apart, the center distance L1 between two adjacent conveyor belts 11 is the limit distance between vehicles. By reasonably setting the center distance L1 between two adjacent conveyor belts 11, the double-sided chute 25 can be installed between the two conveyor belts 11 so that the double-sided chute 25 can simultaneously receive the goods on the two conveyor belts 11 located on both sides of it. In this embodiment, by reasonably setting the width D of the bottom wall 21 of the double-sided chute 25 and the center distance L1 between two adjacent conveyor belts 11, the ratio between the center distance L1 and the width D of the bottom wall 21 is limited to 25:2 to 45:4, so that the bottom wall 21 of the double-sided chute 25 has a sufficiently large area. When the goods slide into the double-sided chute 25, the contact area between the goods and the planar bottom wall 21 of the double-sided chute 25 can be increased, further reducing the contact area between the goods and the curved surface, thereby reducing the contact area between the side wall of the goods and the double-sided chute 25, effectively reducing the friction between the goods and the double-sided chute 25, and further improving the problem that the goods are difficult to slide down after entering the sorting chute 2.

[0063] In one exemplary embodiment, the center distance L1 between adjacent conveyor belts 11 can be set to 3500mm, and the width D of the bottom wall 21 of the double-sided chute 25 can be set to 300mm, so that the center distance L1:width D is 35:3.

[0064] In some implementations of this application, such as Figure 3a and Figure 3b As shown, Figure 3b for Figure 3a A partial enlarged view of point M1. There are multiple sorting chutes 2; some sorting chutes 2 are arranged in the forward direction, and the first to second ends of the bottom wall 21 of the forward-arranged sorting chutes 2 are in the same direction as the movement direction of the conveyor belt 11 in the horizontal plane; other sorting chutes 2 are arranged in the reverse direction, and the first to second ends of the bottom wall 21 of the reverse-arranged sorting chutes 2 are in the opposite direction to the movement direction of the conveyor belt 11 in the horizontal plane.

[0065] In this embodiment, some sorting chutes 2 are arranged in the same direction as the conveyor belt 11. When goods slide out of the outlet of the sorting chutes 2 arranged in the same direction, the horizontal movement direction of the goods is the same as the movement direction of the conveyor belt 11. Other sorting chutes 2 are arranged in the opposite direction to the conveyor belt 11. When goods slide out of the outlet of the sorting chutes 2 arranged in the opposite direction, the horizontal movement direction of the goods is opposite to the movement direction of the conveyor belt 11. By arranging the sorting chutes 2 in both directions, sorting of goods in different directions is achieved.

[0066] In some implementations of this application, such as Figures 4 to 7 As shown, Figure 4 A schematic diagram of the structure of the parallel double-sided chute arranged in the forward direction in the transportation platform provided in this application; Figure 5 for Figure 4 Top view; Figure 6 A schematic diagram of a single-sided chute arranged in the forward direction in the transportation platform provided in this application; Figure 7 for Figure 6 The top view. The angle α between the projection of the first sidewall 22 of the sorting chute 2, which is arranged in the forward direction, and the direction of movement of the conveyor belt 11 on the horizontal plane is 50°±2°.

[0067] In this embodiment, when sorting goods in the forward direction, the goods enter the forward-oriented sorting chute 2. Since the sliding trajectory of the goods is similar to that of a cardboard box, its speed is relatively high. At this time, the angle α between the projection of the first sidewall 22 and the moving direction of the conveyor belt 11 on the horizontal plane is set to 50°±2°. Compared with the design where the first sidewall 22 is completely perpendicular to the moving direction of the conveyor belt 11 in the horizontal direction, the angle at which the goods enter the sorting chute 2 is smaller, allowing the goods to enter the sorting chute 2 from a smaller angle. Thus, when the goods enter the sorting chute 2 from the side with the smaller angle, they can gradually slide down against the first sidewall 22. Under the inertia and the guiding action of the first sidewall 22, the goods slide to the bottom wall 21 and contact the plane. In other words, by reducing the angle α between the projection of the first sidewall 22 and the conveyor belt 11 on the horizontal plane, the goods can always slide in the sorting chute 2 in close contact with the inner wall of the sorting chute 2, thereby reducing the sliding speed of the goods in the sorting chute 2 and effectively improving the problem of damage to some fragile goods (such as plastic bottled liquids and heavy cardboard boxes) caused by excessive sliding speed.

[0068] For the reverse-configured sorting chute 2, such as Figures 8 to 11 As shown, Figure 8 A schematic diagram of the reverse-configured double-sided chute in the transportation platform provided in this application; Figure 9 for Figure 8 Top view; Figure 10 A schematic diagram of the reverse-configured single-sided chute in the transportation platform provided in this application; Figure 11 for Figure 10 A top view. When goods are sorted in reverse, their sliding trajectory is a 90° curved trajectory. During the sliding process, the goods will reduce their speed under the action of centrifugal force. Therefore, the sliding speed of the goods in the reverse-set sorting chute 2 is moderate, and the damage rate of the goods is low.

[0069] In one exemplary embodiment, the included angle α can be set according to the throwing angle of the balance wheel mechanism 111. When the throwing angle of the balance wheel mechanism 111 is between 30° and 45°, the included angle α can be set to 50°±2° as described in the previous embodiment. Specifically, when the throwing angle of the balance wheel mechanism 111 is 40°, the included angle α can be set to 49°. Of course, the throwing angle and included angle α of the balance wheel mechanism 111 can also be set to other values ​​according to actual needs, as long as the goods can fit against the inner wall of the sorting chute 2 when entering the sorting chute 2.

[0070] In some implementations of this application, such as Figure 2 and Figure 3aAs shown, there is at least one set of conveyor belts, each set of conveyor belts including a first conveyor belt 31 and a second conveyor belt 32; at least one set of sorting chutes 2 is provided between the first conveyor belt 31 and the second conveyor belt 32 in the same set; each set of sorting chutes 2 includes sorting chutes 2 arranged in the same direction and sorting chutes 2 arranged in the opposite direction, and the sorting chutes 2 arranged in the same set in the same direction and in the opposite direction are arranged in opposite directions along the movement direction of the conveyor belt 11; the first conveyor belt 31 is connected to the outlet of the sorting chutes 2 arranged in the same direction; the second conveyor belt 32 is connected to the outlet of the sorting chutes 2 arranged in the opposite direction; the minimum distance d between the first conveyor belt 31 and the second conveyor belt 32 in the same set on the horizontal plane is 5800mm.

[0071] In this embodiment, a conveyor belt can be installed at the outlet of the sorting chute 2. When goods slide out of the sorting chute 2, they can directly enter the conveyor belt and be transported to the designated sorting area by the conveyor belt. For example, Figure 2 As shown, the forward-facing sorting chute 2 and the reverse-facing sorting chute 2 can be arranged back-to-back along the direction of movement of the conveyor belt 11, that is, the two types of sorting chute 2 are arranged in a back-to-back manner, so that the outlets of the two types of sorting chute 2 are set opposite. In this case, a first belt conveyor 31 can be set at the outlet of the forward-facing sorting chute 2, and a second belt conveyor 32 can be set at the outlet of the reverse-facing sorting chute 2, so that the goods can fall onto the belt conveyor when they slide out of the outlet of the sorting chute 2. Figure 3a As shown, the minimum distance d between adjacent first belt line 31 and second belt line 32 is 5800mm, which allows two sorting chutes 2 to be accommodated between them.

[0072] Of course, the minimum distance d can be set to other values ​​according to the specific size of the sorting chute 2, as long as it can accommodate at least two sorting chute 2s set opposite to each other along the movement direction of the conveyor belt 11.

[0073] In some implementations of this application, such as Figure 12 As shown, Figure 12 for Figure 3a A partial enlarged view of point M2. Goods on conveyor belt 11 enter the swing wheel mechanism 111 from the first end of the swing wheel mechanism 111; there are multiple sorting chutes 2; the outlet of some sorting chutes 2 is located above the outlet of another sorting chutes 2; the first interval L2 between the inlet of the sorting chutes 2 with the outlet located below and the first end of the swing wheel mechanism 111 is 200mm ± 5mm; the second interval L3 between the inlet of the sorting chutes 2 with the outlet located above and the first end of the swing wheel mechanism 111 is 50mm ± 5mm.

[0074] In this embodiment, the angle α between the first sidewalls 22 on both sides of the inlet of the sorting chute 2 and the conveyor belt 11 along the direction of movement is not uniform. Typically, the angle α between the first sidewall 22 closer to the first end of the swing wheel mechanism 111 and the conveyor belt 11 along the direction of movement is smaller than the angle α between the first sidewall 22 on the other side and the conveyor belt 11 along the direction of movement. Therefore, by offsetting the inlet of the sorting chute 2 from the swing wheel mechanism 111, the goods enter the sorting chute 2 closer to the side with the smaller angle. This ensures that the goods slide within the sorting chute 2 always in contact with the inner wall of the sorting chute 2, thereby controlling the sliding speed of the goods within the sorting chute 2 and effectively improving the problem of damage to some fragile goods caused by excessive sliding speed.

[0075] In one exemplary embodiment, the first interval L2 can be 196 mm, and the second interval L3 can be 51 mm. Of course, it can also be adjusted according to the distance between the first belt 31 and the second belt 32, as long as it allows the goods to fit against the inner wall of the sorting chute 2 when they enter the sorting chute 2.

[0076] In some implementations of this application, such as Figure 1 As shown, the first sidewall 22 has a diamond-shaped surface, and the bottom wall 21 is made of flat sheet metal.

[0077] In this embodiment, the first sidewall 22 is configured as a diamond surface, which can control the sliding speed of goods within the sorting chute 2. The bottom wall 21 is constructed of flat sheet metal. The first contact surface 211 can be made from a single, complete flat sheet metal piece, while the second contact surface 212 between the first contact surface 211 and the first sidewall 22 can be formed by splicing multiple flat sheet metal pieces to create folded surfaces with different slopes. Because the flat sheet metal extends horizontally in the width direction, it prevents the goods from converging towards the center of the sorting chute 2 and thus compressing the sidewalls of the goods. This effectively reduces the contact area between the goods and the sorting chute 2, thereby reducing the friction between the sorting chute 2 and the goods that hinders their descent.

[0078] This application also provides a sorting device, including the transport platform described in any of the above embodiments.

[0079] In this embodiment, the transport frame 1 of the transport platform is connected to the delivery vehicle. Goods are transported from the delivery vehicle to the conveyor belt 11 on the transport frame 1. Driven by the conveyor belt 11, the goods move to the sorting chute 2, and enter the sorting chute 2 under the drive of the swing wheel mechanism 111. Finally, the goods slide onto the belt conveyor, completing the sorting of the goods.
