Description

Technical Field

[0001] The present invention relates to the technical field related to logistics loading and unloading, and specifically relates to a conveyor for logistics loading and unloading. Background Art

[0002] Logistics loading and unloading refers to the process of loading or unloading goods into or from a transportation device manually or mechanically at a designated location. By loading and unloading logistics, the various stages of logistics can be connected, making the individual processes in logistics become a continuous flow process, thus achieving the effect of improving the efficiency of logistics transportation. In the existing market, logistics loading and unloading generally involves the transfer of logistics between a logistics vehicle and a designated location. To improve the efficiency of logistics transportation, the loading and unloading of logistics has gradually tended to develop towards intelligence. The traditional manual loading and unloading of logistics goods has gradually been replaced by loading and unloading conveyors. The existing logistics loading and unloading conveyors in the market are generally set as an inclined conveyor belt structure. Workers place logistics goods on one side at the bottom. Then, the goods move to the top along the conveyor belt structure and enter the interior of the transport vehicle, where they are taken by the workers here, thus completing the loading and unloading work of the goods. For example, the loading and unloading method disclosed in an automatic loading and unloading device for logistics transportation with the application number 202421583479.1;

[0003] However, when the above-mentioned loading and unloading device transports logistics goods, since there is a certain distance between the workers at the head and tail positions of the device, they cannot communicate in a timely manner about the emergencies that occur during the loading process in the transport vehicle. Further, when the goods are not loaded in a timely manner at the top by the workers, at this time, due to the frequent loading of goods by the workers at the bottom, there will be a phenomenon of goods piling up inside the transport vehicle. This will affect the normal loading and unloading work of the workers. And since the height inside the transport vehicle is relatively high, a large amount of time is required for climbing when loading and unloading goods inside the vehicle, which will increase the frequency of goods piling up at the top. Therefore, when the workers carry out the loading and unloading of goods, the efficiency is not high. Summary of the Invention

[0004] The purpose of the present invention is to provide a conveyor for logistics loading and unloading, so as to solve the problem proposed in the above background technology. When the current loading and unloading devices on the market are used to convey logistics goods, since the staff at the head and tail positions of the device are at a certain distance, they cannot communicate in time about the emergencies that occur during the loading process in the transport vehicle. Further, when the goods are not loaded in time at the top by the staff, at this time, since the staff at the bottom frequently perform the loading work of the goods, the phenomenon of goods piling up inside the transport vehicle will occur. This will affect the normal loading and unloading work of the staff. Moreover, since the height inside the transport vehicle is relatively high, a large amount of time is required for climbing when loading and unloading goods inside the vehicle. Therefore, the frequency of goods piling up at the top will increase. As a result, the efficiency of the staff during the loading and unloading of goods is not high.

[0044] Please refer to Figures 1 - 11, the present invention provides a technical solution: a conveyor for logistics loading and unloading, including a support assembly 1 for fixing the entire conveyor. At the top of the support assembly 1, a conveying assembly 2 is provided for transporting logistics goods. At the top of the conveying assembly 2, a telescopic assembly 4 is provided, and at the top of the buffer platform assembly 5, a loading and unloading assembly is provided. The loading and unloading assembly enters the interior of the loading and unloading vehicle through the telescopic assembly 4 to perform the logistics loading and unloading work. At the bottom of the conveying assembly 2, an adjusting assembly 3 is provided for adjusting the conveying height of the conveying assembly 2. The loading and unloading assembly includes a buffer platform assembly 5 and a working platform 6. The buffer platform assembly 5 is used to buffer the transported logistics to avoid the phenomenon of logistics transportation accumulation. At the bottom of the buffer platform assembly 5, a working platform 6 is provided for the staff to perform the logistics loading and unloading work. The working platform 6 is connected to the bottom of the buffer platform assembly 5 and is used to move along with the position of the buffer platform assembly 5 to achieve flexible logistics loading and unloading work;

[0045] This application provides a conveyor for logistics loading and unloading with a buffer platform assembly 5. Specifically, when in use, the entire conveyor is set at a suitable position on the ground under the action of the support assembly 1. Then, the entire conveyor is connected to an external power supply. The entire conveyor can then perform the logistics loading and unloading work. When loading and unloading, first, it is necessary to control the adjusting assembly 3 to drive the top of one side of the entire conveying assembly 2 to reach a position corresponding to the height of the transport vehicle. Then, start the telescopic assembly 4 to drive the buffer platform assembly 5 into the interior of the transport vehicle. After that, the staff inside the vehicle stands on the working platform 6 and can unload the goods inside the vehicle, making them reach the conveying assembly 2 through the telescopic assembly 4 to complete the unloading work. At the same time, on the ground, goods can also be placed on the conveying assembly 2, so that the goods reach the telescopic assembly 4 along with the conveying assembly 2 and then reach above the buffer platform assembly 5 again for the staff on the working platform 6 to pick up and load the goods.

[0046] Among them, in this application, according to Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the support assembly 1 includes a mounting base plate 11, fixed side plates 12, and support seats 13. Fixed side plates 12 are installed at both sides of the top of one side of the mounting base plate 11. Support seats 13 are provided at the bottom of the mounting base plate 11 for support work. At the top of the mounting base plate 11, an adjusting assembly 3 is connected to the bottom of one side of the conveying assembly 2, and the other side of the conveying assembly 2 is arranged inside the 2 fixed side plates 12;

[0047] Among them, the entire device is set on the ground through the support seats 13. Through the 2 fixed side plates 12, the side of the conveying assembly 2 can be limited.

[0048] When the conveying component 2 is transporting, according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying assembly 2 includes three rotating rollers 21, a conveying belt 22, a fixed support rod 23 and an inclined support rod 24. The three rotating rollers 21 are distributed in an obtuse angle shape, and the conveying belt 22 is arranged outside thereof. The top ends of the two rotating rollers 21 arranged horizontally are connected to the inner wall of the fixed support rod 23 through bearings, and the top ends of the two rotating rollers 21 arranged inclinedly are connected to the inner wall of the inclined support rod 24 through bearings. The fixed support rod 23 is arranged at the outer position of the inclined support rod 24. The top end of the fixed support rod 23 is also provided with a pressing assembly 10 for pressing down and limiting the bending position of the conveying belt 22. The top end axis of the middle rotating roller 21 passes through the fixed support rod 23 and the inclined support rod 24 and is connected to the moving slider 25, and the moving slider 25 slides in the slide groove 231 inside the fixed support rod 23. The outer side of the rotating roller 21 biased toward the higher position is coaxially connected with a driving motor 7 for driving the rotation thereof.

[0049] Specifically, when conveying, it is necessary to start the driving motor 7 so that it drives the rotating roller 21 coaxially connected to its top to rotate. With the arrangement of the conveying belt 22 on the three rotating rollers 21, the conveying belt 22 will be able to convey above two rotating rollers 21, thereby achieving the effect of conveying the goods on its surface.

[0050] Since the adjustment component 3 is arranged at the bottom of the conveying component 2, when adjusting, according to Figure 8 As shown, the adjustment assembly 3 is provided with 2 groups, and includes an adjustment motor 31, a rotating screw 32 and a rotating rod 33. The top of the adjustment motor 31 is coaxially connected with the rotating screw 32, and the outer side of the rotating screw 32 is threadedly connected with a moving seat, and the top of the moving seat is provided with a rotating rod 33 axially connected thereto, and the top of the other side of the rotating rod 33 is connected to the bottom axis of the tilt support rod 24;

[0051] When making adjustments, the adjusting motor 31 needs to be started so that the adjusting motor 31 drives the rotating screw 32 at its top to rotate. When the rotating screw 32 rotates, the moving seat connected to its external thread moves. When the moving seat moves, the rotating rod 33 is driven to rotate. Then, the rotating rod 33 rotates, and the top of the rotating rod 33 drives the tilting support rod 24 to change its angle. At this time, the rotation of the tilting support rod 24 changes the top angle of the conveying assembly 2, thereby driving the height of the loading and unloading assembly to change, so as to achieve the effect of facilitating the adjustment of the height of the loading and unloading assembly according to the different loading and unloading heights in the vehicle.

[0052] In the present application, a tension adjuster is provided at the bottom of the conveying assembly 2, so that when the angle of the inclined support rod 24 changes, the conveying belt 22 can always be in a tensioned state, and a movable slider 25 is provided on the outer side of the middle rotating roller 21 to move inside the slide groove 231. Therefore, when the angle of the entire inclined support rod 24 changes, the entire conveying assembly 2 can also move inside the fixed side plate 12, and thus there will be no motion interference.

[0053] When the telescopic component 4 controls the telescopic movement, Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, the telescopic assembly 4 is connected to the conveying assembly 2 via a fixed assembly 8, and the telescopic assembly 4 includes two groups of prismatic telescopic frames 41 and a rotating assembly 42. The rotating assembly 42 is evenly spaced at the middle position of the top ends of the two groups of prismatic telescopic frames 41, and the rotating assembly 42 includes a rotating wheel 421 and a rotating motor 422. The top end of the rotating wheel 421 passes through the bearing in the through hole at the top end of the prismatic telescopic frame 41 and is connected to the rotating motor 422.

[0054] The fixing assembly 8 includes a connecting vertical plate 81, a fixing cross bar 82, an intermediate cross bar 83 and a first circular shaft 84. The top of the connecting vertical plate 81 is connected to the bearings on both sides of the external shaft of the rotating roller 21, and the bottom thereof is fixed with a fixing cross bar 82. The bottom of the fixing cross bar 82 is fixed with an intermediate cross bar 83 toward the rotating roller 21, and the outer side of the intermediate cross bar 83 is connected to the bottom bearing of one side of the prismatic telescopic frame 41. A pushing assembly 9 is also provided at the top of the intermediate cross bar 83 to connect with the working platform 6 and the other side of the prismatic telescopic frame 41.

[0055] The pushing assembly 9 includes a pushing cylinder 91, a rectangular column 92, a second circular shaft 93 and a connecting frame 94. The bottom of the pushing cylinder 91 is connected to the middle position of the middle crossbar 83, and the top of the pushing cylinder 91 is connected to the rectangular column 92. The second circular shaft 93 is arranged outside the rectangular column 92 and connected to the bottom bearing of the other side of the prismatic telescopic frame 41. The bottom of the rectangular column 92 is also provided with a "U"-shaped connecting frame 94 connected to the bottom of the fixed frame 51.

[0056] Specifically, when controlling the expansion and contraction of the telescopic component 4, it is necessary to start the pushing cylinder 91 in the middle of the middle crossbar 83, so that its top drives the rectangular column 92 to move inlay. When the rectangular column 92 moves forward, it will drive the second circular shaft 93 outside it to move. Thus, the second circular shaft 93 drives the outer top of the rhombic telescopic frame 41 to move outwards, so that the entire rhombic telescopic frame 41 is in an unfolded state, and thus the rotation components 42 arranged at equal intervals at its top are evenly distributed. Then, start the rotation motor 422, and the rotation roller 421 at its top will rotate. Thus, the goods reaching the rotation roller 421 through the conveying component 2 will continue to be conveyed as the rotation component 42 rotates, and finally reach above the buffer platform component 5;

[0057] In this application, since a connection frame 94 is provided at the top of the rectangular column 92 to connect with the buffer platform component 5, when the telescopic component 4 expands and contracts, it will drive the buffer platform component 5 to move forward together.

[0058] According to Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, the buffer platform component 5 includes a fixed frame 51, a conveying cylinder 52, a middle hole 53 and a rotating plate 54. The conveying cylinders 52 distributed obliquely at equal intervals are arranged on both sides of the fixed frame 51 for the buffer falling work of logistics. A through middle hole 53 is also provided at the middle position of the fixed frame 51. A rotating plate 54 is arranged in the middle of the middle hole 53, and the rotating plate 54 is controlled to rotate by a control component 55 outside the fixed frame 51. The control component 55 includes a control motor 551, a driving gear 552 and a driven gear 553. The control motor 551 is arranged at a partial position at the bottom of the fixed frame 51, and its top is coaxially connected with the driving gear 552. The top of the driving gear 552 meshes with the driven gear 553, and the middle shaft of the driven gear 553 is connected to the middle axis position of the rotating plate 54;

[0059] Specifically, the goods conveyed by the rotating component 42 will finally reach the rotating plate 54 in the middle of the fixed frame 51. At this time, the staff can timely obtain and take the goods. At the same time, the control motor 551 can also be started to drive the driving gear 552 at its top to rotate and mesh with the driven gear 553. Thus, the driven gear 553 drives the rotating plate 54 to rotate and tilt, so that the goods reach the two inclined conveying cylinders 52, and are conveyed downwards for stacking and buffering along the inclined structure of the conveying cylinders 52 for the staff to take and use;

[0060] Since the goods can be stacked on both sides, sufficient time is provided for the loading and unloading work of the staff, so there will be no phenomenon that the goods are conveyed too fast and a large amount of them are piled up in the vehicle.

[0061] When the staff are working, according to Figure 5 and Figure 9 As shown, the working platform 6 includes a telescopic cylinder 61 and a working plate 62. The bottom of the telescopic cylinder 61 is provided with a working plate 62 in a "U" - shaped structure, and the top of the telescopic cylinder 61 is arranged at both sides of the bottom of the fixed frame 51. The outer dimension of the working plate 62 is larger than the outer dimension of the fixed frame 51.

[0062] Specifically, when loading and unloading, the staff can directly stand on the working plate 62 and move to any position. Since it is arranged at the outer edge position of the bottom of the fixed frame 51, the goods at any position on the fixed frame 51 can be flexibly picked up, and they can also move flexibly according to the different loading and unloading positions of the goods in the vehicle. At the same time, the telescopic cylinder 61 can be adjusted to drive the working plate 62 to move up and down. Thus, there is no need to climb high for loading and unloading. On the premise of ensuring the safety of the staff, the efficiency of goods loading and unloading can be improved.

[0063] In this application, according to Figure 11 As shown, the pressing component 10 includes a mounting frame body 101 and a pressing roller 102. The mounting frame body 101 is installed above the fixed support rod 23, and a pressing roller 102 is arranged inside its bearings. Two groups of pressing components 10 are symmetrically arranged on both sides of the bending position of the conveyor belt 22, and a friction strip is also arranged at the middle position above the conveyor belt 22;

[0064] Specifically, the pressing roller 102 can limit the middle position of the conveyor belt 22 to ensure that there is no phenomenon of the middle part warping up. At the same time, through the setting of the friction strip made of rubber or silica gel, the friction between the goods and the conveyor belt 22 can be increased, ensuring that both bagged goods and boxed goods can be transported.
