Description

Technical Field

[0001] The present invention mainly relates to the technical field of sorting machines, and in particular to a sorting machine with a cargo frame self-adapting function. Background Art

[0002] Sorting machines play a vital role in logistics, warehousing and many other industries that require the classification and sorting of goods. Traditional sorting machines mostly use fixed-structure conveying devices and load-bearing platforms, which have many limitations when faced with diverse cargo box sizes and complex site layout requirements.

[0003] The conveying plane height of many sorting machines is fixed and cannot be flexibly matched with subsequent conveying equipment (such as multi-layer conveyors) set at different heights. For example, in some large warehouses, in order to make full use of space, multi-layer conveyors are often set at different height levels according to storage areas and sorting processes. However, since traditional sorting machines cannot adjust the conveying height of the cargo frame, they can only rely on additional ramps and complex transfer devices to connect equipment at different heights. This not only increases equipment costs, but also easily causes jams and drops during cargo transfer, affecting sorting efficiency and cargo integrity.

[0004] In terms of the adaptability of the size of the cargo box, traditional sorting machines are usually designed according to the cargo box of a specific standard size. When encountering cargo boxes of different sizes such as width and height, they are either unable to be effectively fixed, causing the cargo box to shake during transportation or even fall off the conveying track, causing damage to the goods; or they need to manually adjust the relevant parts of the equipment to adapt to the new cargo box size. This method is inefficient, and frequent adjustments are prone to wear and tear of equipment parts, increasing the maintenance cost of the equipment. At the same time, it is difficult to meet the increasingly diversified needs of cargo packaging specifications in the modern logistics industry. Summary of the invention

[0026] The spacing adjustment component 7 includes a mounting frame 71, on which a fixed mounting bar 75 is provided. The mounting frame 71 is also provided with an adjustment mechanism 77, and a movable mounting bar 76 is provided at the output end of the adjustment mechanism 77. The adjustment mechanism 77 is used to drive the movable mounting bar 76 to move closer to or away from the fixed mounting bar 75.

[0027] A screw sleeve mounting hole 72 for mounting the screw sleeve 23 is provided on one side of the mounting frame 71, and an avoidance hole 73 is provided on the other side. The avoidance hole 73 is used to avoid the first screw rod 22 on the other side. A plurality of guide columns 8 are arranged in the frame 1, and a guide hole 74 is provided on the mounting frame 71. The guide hole 74 is slidably sleeved in the guide column 8.

[0028] The adjusting mechanism 77 includes two second screw rods 772 rotatably mounted on the mounting frame 71, the two second screw rods 772 are connected via a second sprocket assembly 777, one end of the second screw rod 772 away from the second sprocket assembly 777 is connected to the third motor 771, and a threaded barrel 774 is threadedly mounted on the second screw rod 772, and the threaded barrel 774 is connected to the movable mounting strip 76.

[0029] A moving block 773 is disposed on the outer side of the threaded cylinder 774 , a guide shaft 775 is disposed parallel to the lower side of the second screw rod 772 , a guide groove 776 is formed on the moving block 773 , and the guide groove 776 is slidably mounted on the guide shaft 775 .

[0030] The movable installation bar 76 and the fixed installation bar 75 are both provided with a conveyor belt 41 , and the conveyor belt 41 is operated by a driving mechanism 42 .

[0031] The driving mechanism 42 includes a hexagonal shaft 423 rotatably mounted on the mounting frame 71, the hexagonal shaft 423 is connected to the second motor 421 through the first sprocket assembly 422, and a driving pulley 424 is rotatably mounted on the movable mounting bar 76 and the fixed mounting bar 75 respectively, the driving pulley 424 is sleeved on the hexagonal shaft 423, and driven pulleys 425 are rotatably mounted at both ends of the movable mounting bar 76 and the fixed mounting bar 75, the conveyor belt 41 is sleeved on the driving pulley 424 and the driven pulley 425, and a pad 426 is arranged under the upper conveyor belt 41.

[0032] Working principle: The power supply of the sorting machine is turned on, and the power components such as the first motor 21, the second motor 421, and the third motor 771 are in a waiting state. At this time, the spacing adjustment component 7 of the cargo frame clamping mechanism 5 and the spacing adjustment component 7 of the cargo frame transfer platform 4 are in the initial setting position, and the spacing between the clamping block 51 and the conveyor belt 41 is initially adjusted according to the preset cargo frame 9 size range. The conveyor belts 41 have not started to operate yet, and the entire sorting machine is ready to receive the cargo frame for sorting operation.

[0033] When facing cargo frames 9 of different widths, the cargo frame clamping mechanism 5 and the spacing adjustment assembly 7 on the cargo frame transfer platform 4 begin to play a role. Start the third motor 771, the third motor 771 drives a second screw rod 772 connected thereto to rotate, and through the transmission of the second sprocket assembly 777, the two second screw rods 772 rotate synchronously in the same direction. Since the threaded barrel 774 and the second screw rod 772 are installed by threads, and the moving block 773 on the outer side of the threaded barrel 774 is slidably guided along the guide shaft 775 through the guide groove 776, it is ensured that the threaded barrel 774 can only move linearly along the second screw rod 772, thereby driving the movable mounting strip 76 to approach or move away from the fixed mounting strip 75, so that the spacing between the clamping blocks 51 on the cargo frame clamping mechanism 5 and the width of the conveyor belt 41 on the cargo frame transfer platform 4 can be adaptively adjusted according to the actual width of the cargo frame 9, ensuring the effective fixation and stable placement of the cargo frame 9.

[0034] According to the height requirement of the cargo frame 9, the first lifting mechanism 2 is started (the second lifting mechanism 3 is the same, and the two have the same structure). The first motor 21 starts to run, driving the first screw 22 to rotate. Since the screw sleeve 23 and the first screw 22 are threadedly matched, and the screw sleeve 23 is installed in the screw sleeve mounting hole 72 of the mounting frame 71, and the mounting frame 71 is guided up and down along the guide column 8 through the guide hole 74, the mounting frame 71 is smoothly lifted and lowered as the screw sleeve 23 moves up and down. The first lifting mechanism 2 drives the cargo frame transfer platform 4 to rise or fall, and the second lifting mechanism 3 drives the cargo frame clamping mechanism 5 to rise or fall, thereby adjusting the distance between the cargo frame transfer platform 4 and the cargo frame clamping mechanism 5 to be suitable for the height of the cargo frame 9.

[0035] After the size self-adaptation adjustment is completed, the driving mechanism 42 is started to drive the conveyor belt 41 to operate so as to convey the cargo frame 9. The second motor 421 starts to work, driving the hexagonal shaft 423 to rotate, and the hexagonal shaft 423 transmits power through the first sprocket assembly 422, so that the driving pulley 424 sleeved on the hexagonal shaft 423 starts to rotate, thereby driving the conveyor belt 41 to circulate along the driving pulley 424 and the driven pulley 425, and the pad 426 under the upper conveyor belt 41 plays a role of supporting and assisting the conveying, and is ready to smoothly convey the cargo frame 9 from the cargo frame transfer table 4 to the multi-layer conveyor 6.

[0036] As the conveyor belt 41 operates, the cargo frame 9 placed on the cargo frame transfer table 4 begins to move toward the multi-layer conveyor 6, and is finally transported to the corresponding level of the multi-layer conveyor 6. Subsequently, the multi-layer conveyor 6 can transport the cargo frame 9 to different destinations for further processing or storage according to preset sorting rules, thereby completing the transportation and transfer operations of the cargo frame in the entire sorting process.

[0037] A working process: first, the first lifting mechanism 2 drives the cargo frame transfer platform 4 to descend, and then, according to the width of the cargo frame 9, the spacing adjustment component 7 is started to adjust the distance between the two conveyor belts 41, and after the cargo frame 9 to be sorted is placed on the cargo frame transfer platform 4, the cargo frame clamping mechanism 5 is driven to descend by the second lifting mechanism 3, and then the spacing adjustment component 7 controls the clamping block 51 to clamp the cargo frame 9, and then the first lifting mechanism 2 and the second lifting mechanism 3 operate synchronously, thereby driving the cargo frame transfer platform 4 (and the cargo frame clamping mechanism 5 above as a whole) to rise or fall to a specified height position, so as to subsequently convey the cargo frame 9 to the multi-layer conveyor 6 at a suitable level.

[0038] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
