Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, specifically to a logistics conveying equipment. Background Technology

[0002] Logistics is the entire process of planning, implementing, and managing the movement of raw materials, semi-finished products, finished products, and related information from the place of origin to the place of consumption, through transportation, storage, and distribution, in order to meet customer needs at the lowest cost. Logistics requires unloading and conveying equipment during the handling of goods.

[0003] In traditional logistics, after goods are sorted and classified, staff need to move each item onto a conveyor belt. This process is labor-intensive, and when there are many goods, it is not convenient to place them on the conveyor belt in a concentrated manner, resulting in low logistics efficiency.

[0004] In the prior art, patent application number 202210186218.5 discloses a logistics unloading and conveying component. This component raises the goods via a conveyor structure and then uses a flipping structure to throw the goods onto the conveyor belt. While this avoids the need for logistics personnel to manually carry heavy goods onto the conveyor belt, saving manpower, some goods need to be placed upright at all times. If the flipping structure is used to throw the goods onto the conveyor belt, the goods will be upside down, potentially damaging the contents. Summary of the Invention

[0005] In order to solve at least one of the technical problems mentioned in the background art, the present invention aims to provide a logistics conveying device to prevent goods from being upside down and avoid damage to the internal items.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A logistics conveying device includes a conveyor frame with several conveying layers and conveyor belts on each layer. Several lifting frames are located on one side of the conveyor frame, with lifting platforms slidably connected to each frame. A lifting mechanism for driving the lifting platforms to move up and down is provided on each lifting frame. Several guide plates for conveying goods to the conveyor belts are hinged to each conveying layer, and several guide rollers are rotatably connected to each guide plate. Each guide plate on each conveyor belt corresponds to a lifting platform. A rotating mechanism for driving the guide plates to rotate is provided on each conveying layer. An infrared detection component for detecting the presence of goods is also provided on each conveying layer, corresponding to each guide plate. The infrared detection component is electrically connected to a PLC, which is electrically connected to the rotating mechanism on the corresponding guide plate. When the infrared detection component detects goods, the PLC controls the rotating mechanism to lift the guide plate.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] Goods are placed on the lifting platform, which is then driven upwards by the lifting mechanism. As the platform moves from bottom to top and aligns with the bottommost guide plate, the goods are moved horizontally and smoothly onto it. Once the goods are fully on the guide plate, they are detected by the infrared detection component. At this point, the PLC-controlled rotating mechanism tilts the guide plate, preventing it from completely tipping over, allowing the goods to slide smoothly onto the conveyor belt. This effectively prevents the goods from tipping over and protects the contents from damage. Using multiple lifting platforms prevents excessive spacing between goods, improving handling efficiency. However, to prevent collisions, when the infrared detection component detects goods on the conveyor belt opposite a guide plate, the PLC-controlled rotating mechanism tilts the guide plate. The lifting mechanism then drives the platform upwards, but it doesn't align with a guide plate containing goods; instead, it continues upwards until it reaches a level without goods, preventing congestion and overload.

[0010] Preferably, the guide plate has a groove on the side near the lifting frame, the groove opening downwards, and a protrusion matching the groove is provided on the lifting platform, with a contact switch on the upper side of the protrusion; the lifting platform is provided with a feeding pulley assembly, and a pulley motor for driving the feeding pulley assembly to transport goods is provided on the lifting platform; the guide plate is provided with a roller motor for driving the guide roller to rotate; when the contact switch abuts against the top wall of the groove, the pulley motor and the roller motor start.

[0011] Preferably, the lifting frame has a feeding ramp on the side away from the conveyor frame, and when the lifting platform is at its bottom, the top of the feeding ramp and the top surface of the lifting platform are on the same plane.

[0012] Preferably, a feeding assembly is provided between the feeding ramp and the lifting frame. The feeding assembly includes a plane connected to the top of the feeding ramp, a slide rod slidably connected to the lifting frame, a push plate fixed to the end of the slide rod, and a baffle fixed to the end of the push plate. The lifting frame is provided with a gear and a gear motor for driving the gear to rotate. A rack is provided on the slide rod, and the gear meshes with the rack for transmission.

[0013] Preferably, the two ends of the conveyor layer are the inlet end and the outlet end, respectively, and the conveyor belt conveys the goods in the direction from the inlet end to the outlet end.

[0014] Preferably, the infrared detection component includes a first infrared sensor and a second infrared sensor, wherein the first infrared sensor is directly opposite the corresponding guide plate, and the second infrared sensor is located on the side of the guide plate closer to the inlet end.

[0015] Preferably, the rotating mechanism includes an electric push rod fixed on the conveying layer, a limiting slide rail fixed at the bottom of the guide plate, and the top end of the electric push rod slidably connected to the inner wall of the limiting slide rail.

[0016] Preferably, when the guide plate is horizontal, the height of the guide plate is not lower than the height of the upper surface of the conveyor belt on the conveying layer.

[0017] Preferably, the lifting mechanism includes an electric slide rail formed on the lifting frame, and a slider that matches the electric slide rail is provided on the lifting platform, and the electric slide rail drives the slider to move up and down.

[0018] Preferably, the lifting mechanism includes a scissor mechanism fixed on the lifting frame, and the output end of the scissor mechanism is fixed at the bottom of the lifting platform. Attached Figure Description

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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 without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 and Figure 4 This embodiment provides a logistics conveying device, including a conveyor frame 1, on which two conveyor layers 10 are provided, and a conveyor belt 11 is provided on the conveyor layer 10. The two ends of the conveyor layer 10 are respectively the inlet end 101 and the outlet end 102. The conveyor belt 11 conveys goods in the direction from the inlet end 101 to the outlet end 102.

[0029] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, each conveying layer 10 is hinged with three guide plates 2 for conveying goods to the conveyor belt 11. The three guide plates 2 are arranged horizontally, and the bottom of the guide plate 2 is provided with a platform, which ensures that the guide plate 2 can only rotate to a horizontal position at its lowest point. When the guide plate 2 is horizontal, its height is not lower than the height of the upper surface of the conveyor belt 11 on the conveying layer 10. The conveying layer 10 is provided with a rotating mechanism for driving the guide plate 2 to rotate. The rotating mechanism includes an electric push rod 22 fixed to the conveying layer 10, and a limiting slide rail 23 fixed to the bottom of the guide plate 2. The top end of the electric push rod 22 is slidably connected to the inner wall of the limiting slide rail 23. A plurality of guide rollers 21 are rotatably connected to the guide plate 2, and a roller motor for driving the guide rollers 21 to rotate is provided on the guide plate 2.

[0030] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 In this embodiment, three lifting frames 3 are provided on one side of the conveyor frame 1. Lifting platforms 31 are slidably connected to the lifting frames 3. Lifting mechanisms for driving the lifting platforms 31 to rise and fall are provided on the lifting frames 3. The three guide plates 2 on each conveyor belt 11 correspond one-to-one with the three lifting platforms 31. The lifting mechanism includes an electric slide 30 opened on the lifting frame 3. The lifting platform 31 is provided with a slider that matches the electric slide 30. The electric slide 30 drives the slider to rise and fall.

[0031] The conveying layer 10 is equipped with an infrared detection component 12 for detecting whether there is cargo. The infrared detection component 12 includes a first infrared sensor 121 and a second infrared sensor 122. The first infrared sensor 121 is directly opposite the corresponding guide plate 2, and the second infrared sensor 122 is located on the side of the guide plate 2 near the receiving end 101 (it is worth noting that if the distance from the guide plate 2 near the receiving end 101 to the receiving end 101 is less than the length of a courier package, then the second infrared sensor 122 is not installed at that location). The infrared detection component 12 is electrically connected to a PLC, and the PLC is electrically connected to an electric push rod 22 on the corresponding guide plate 2. When the infrared detection component 12 detects cargo, the PLC controls the electric push rod 22 to extend and lift the guide plate 2.

[0032] The guide plate 2 has a groove 20 on the side near the lifting frame 3, with the groove 20 opening downwards. The lifting platform 31 has a protrusion 311 that matches the groove 20, and a contact switch 312 is provided on the upper side of the protrusion 311. The lifting platform 31 is provided with a feeding pulley assembly, and the lifting platform 31 is provided with a pulley motor for driving the feeding pulley assembly to transport goods. When the contact switch 312 abuts against the top wall of the groove 20, the pulley motor and the roller motor start.

[0033] During operation, the first infrared sensor 121 and the second infrared sensor 122 first detect whether there is cargo at the detectable location. If there is cargo, the electric push rod 22 is extended by the PLC to lift the guide plate 2 until the cargo is removed. Only then is the guide plate 2 laid flat to prevent cargo from colliding with the conveyor belt 11. During the process of transferring cargo from the lifting platform 31 to the conveyor belt 11, the lifting platform 31 first raises the cargo. When the contact switch 312 abuts against the top wall of the groove 20, the lifting platform 31 stops rising, and the pulley motor and roller motor start, so that the cargo is transferred from the lifting platform 31 to the guide plate 2 in sequence, and finally transferred to the conveyor belt 11, completing the transfer of cargo.

[0034] In another embodiment, the lifting mechanism includes a scissor mechanism fixed to the lifting frame 3, the output end of which is fixed to the bottom of the lifting platform 31. Except for the lifting mechanism, all other aspects are the same.

[0035] Please see Figure 1 and Figure 6 In this embodiment, except for the lifting frame 3 closest to the receiving end 101, the other lifting frames 3 are provided with a feeding ramp 4 on the side away from the conveyor frame 1. When the lifting platform 31 is at the bottom, the top of the feeding ramp 4 and the top surface of the lifting platform 31 are on the same plane. Rollers can be installed on the feeding ramp 4 to facilitate pushing the goods onto the lifting platform 31.

[0036] Please see Figure 1 and Figure 5 In this embodiment, a feeding assembly 5 is provided between the feeding ramp 4 and the lifting frame 3 closest to the infeed end 101. The feeding assembly 5 includes a plane 51 connected to the top of the feeding ramp 4, a slide rod 52 slidably connected to the lifting frame 3, a push plate 53 fixed to the end of the slide rod 52, and a baffle 54 fixed to the end of the push plate 53. The lifting frame 3 is provided with a gear and a gear motor for driving the gear to rotate. The slide rod 52 is provided with a rack, and the gear meshes with the rack. Transmission: When the lifting platform 31 is at its lowest point, the top surface of the plane 51 and the top surface of the lifting platform 31 are on the same plane. Through the meshing of gears and racks, the push plate 53 is driven to move towards the lifting platform 31, pushing the goods onto the lifting platform 31. The baffle 54 can prevent the goods from sliding off the plane 51. The front side of the plane 51 is provided with a feeding ramp 4. The top of the feeding ramp 4 and the top surface of the plane 51 are on the same plane. Rollers can be installed on the feeding ramp 4 and the plane 51 to facilitate pushing the goods onto the lifting platform 31.

[0037] In this embodiment, lighter goods can be placed directly onto the conveyor belt 11 from the inlet 101. Under the detection of the infrared detection component 12, there will be no problem of goods collision.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
