Description

Technical Field

[0001] This invention relates to the field of cargo transportation technology, and more specifically to a logistics cargo dispatching device with loading and unloading functions. Background Technology

[0002] Logistics and goods are the lifeblood of the real economy. Their efficient, safe, and low-cost flow directly affects the competitiveness of enterprise supply chains, the efficiency of social resource allocation, and the operating costs of the national economy. Optimizing the operational level of goods in transit and transshipment is a key breakthrough to improve overall logistics efficiency.

[0003] The shortcomings of existing technologies: In the logistics cargo transfer process, when goods need to be stacked on pallets, existing equipment cannot tightly fit the layers of goods together. When the stack reaches a certain height, the overall stability is insufficient, and there is a risk of shaking or even tipping over during transfer. In order to ensure stability during transportation, it is often necessary to reduce the number of stacking layers, which directly reduces the amount of goods transferred in a single transfer, and also reduces space utilization and transfer efficiency. To address this, we propose a logistics cargo scheduling device with loading and unloading functions. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a logistics cargo scheduling device with loading and unloading functions to solve the problems existing in the background art.

The material conveying mechanism includes a mounting frame, guide rods, a lifting seat, and a lifting frame. The mounting frame is installed between the lower frame and the upper frame. Multiple guide rods are installed inside the mounting frame. The lifting seat is slidably connected to the circumferential surface of the guide rods. The lifting frame is installed on the surface of the lifting seat, and a material tray is placed at the upper end of the lifting frame. The support column is equipped with a sorting mechanism, which includes a bidirectional lead screw, a threaded block, a connecting seat, and a positioning frame. Multiple bidirectional lead screws are rotatably connected to the support column, and multiple sets of threaded blocks are slidably connected to the support column. Each threaded block is threadedly connected to the bidirectional lead screw, and a connecting rod is rotatably connected to the surface of each threaded block. A connecting seat is rotatably connected to the end of each connecting rod away from the threaded block, and a rotating rod is installed inside the connecting seat. The positioning frame is installed on the circumferential surface of the rotating rod and is located around the material tray. Preferably, a lifting screw is rotatably connected inside the mounting frame, the lifting seat is threadedly connected to the lifting screw, and the output end of the servo motor mounted on the upper end of the mounting frame is fixedly connected to the lifting screw.

[0006] Preferably, a drive motor is installed on the upper end of the upper frame, a drive shaft is installed on the output end of the drive motor, the drive shaft is connected to the bidirectional lead screw through a first sprocket set, and the bidirectional lead screws are connected to each other through a second sprocket set.

[0007] Preferably, the material handling mechanism includes a support frame, a guide shaft, a suspension frame, a slide rail, a slider, a mounting shell, and a suction cup. The support frame is installed on the upper end of the upper frame, and multiple guide shafts are installed inside the support frame. The suspension frame is slidably connected to the circumferential surface of the guide shafts. The slide rail is installed at the lower end of the suspension frame, and the slider is slidably connected inside the slide rail. A multi-stage electric telescopic rod is installed at the upper end of the slider. The mounting shell is installed at the output end of the multi-stage electric telescopic rod. A rotary motor is installed inside the mounting shell, and a connecting shaft is installed at the output end of the rotary motor. The suction cup is installed at the lower end of the connecting shaft.

[0008] Preferably, a transverse motor is mounted on the surface of the support frame, a first threaded rod is mounted on the output end of the transverse motor, the suspension frame is threadedly connected to the first threaded rod, a longitudinal motor is mounted on the surface of the slide rail, a rotating shaft is mounted on the output end of the longitudinal motor, a second threaded rod rotatably connected inside the slide rail is threadedly connected to the slider, and the rotating shaft is connected to the second threaded rod through a third sprocket set.

[0009] Preferably, a sliding shaft is slidably connected inside the connecting seat, a rack is mounted on the circumferential surface of the sliding shaft, a gear mounted on the circumferential surface of the rotating rod meshes with the rack, and a first spring is installed between the sliding shaft and the connecting seat.

[0010] Preferably, a slide block is installed on the surface of the support column, a sliding frame is slidably connected to the slide block and the lower frame, a second spring is installed between the sliding frame and the lower frame, and pressure blocks are installed on the circumferential surface of the sliding frame, with the pressure blocks fitting against the upper end of the slide shaft.

[0011] Preferably, a downward pressure arm is installed on the surface of the lifting seat, and the downward pressure arm is used to press down the sliding frame.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention involves accurately inserting the lifting frame below the material tray, then controlling the lifting seat to rise vertically within the mounting frame, simultaneously raising the lifting frame and material tray to their highest limit position. After the equipment moves to the side of the material conveying equipment, the material handling mechanism transfers the material boxes one by one onto the material tray. When one layer of material boxes is filled, the bidirectional lead screw begins to rotate, causing the surrounding positioning frames to simultaneously retract inwards, applying uniform pressure to the material boxes on the material tray to achieve a tight and close fit of the boxes in that layer. Subsequently, the positioning frames are controlled to reset outwards, while the lifting seat lowers the material tray and material boxes as a whole, ensuring that the top surface of the current material box is flush with the initial stacking reference surface of the material tray, guaranteeing the material box placement height. Similarly, the material handling mechanism can then continue to stack the material boxes layer by layer, and repeat the above compaction steps after each layer is filled to achieve a tight stacking of multiple boxes. The resulting stable integrated stack greatly reduces the risk of the stack tilting and collapsing due to center of gravity shift, equipment vibration, or external impact. This ensures transportation safety, increases the single-load capacity, and significantly improves cargo transfer efficiency. After the stacking operation is completed, the equipment is moved to the unloading position, the lifting seat is lowered to the lowest point, the lifting frame is detached from the pallet, and the pallet lands smoothly. The equipment is then moved to remove the lifting frame, which enables rapid unloading. The lifting frame can then be reinserted under a new pallet for subsequent transportation operations.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The logistics cargo scheduling equipment with loading and unloading functions involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1-11As shown, in one embodiment, a logistics cargo scheduling device with loading and unloading functions is proposed, including a lower frame 1, a drive wheel set 101 installed at the lower end of the lower frame 1, a support column 102 and a material conveying mechanism 2 installed at the upper end of the lower frame 1, an upper frame 103 installed at the upper end of the support column 102, and a material picking mechanism 3 installed at the upper end of the upper frame 103. The material conveying mechanism 2 includes a mounting frame 201, a guide rod 202, a lifting seat 203 and a lifting frame 204. The mounting frame 201 is installed between the lower frame 1 and the upper frame 103. Multiple guide rods 202 are installed inside the mounting frame 201. The lifting seat 203 is slidably connected to the circumferential surface of the guide rods 202. The lifting frame 204 is installed on the surface of the lifting seat 203. A material tray 205 is placed at the upper end of the lifting frame 204. A sorting mechanism 4 is provided inside the support column 102. The sorting mechanism 4 includes a bidirectional lead screw 401, a threaded block 402, a connecting seat 403, and a positioning frame 406. Multiple bidirectional lead screws 401 are rotatably connected inside the support column 102. Multiple sets of threaded blocks 402 are slidably connected inside the support column 102. The threaded blocks 402 are threadedly connected to the bidirectional lead screws 401. A connecting rod 404 is rotatably connected to the surface of each threaded block 402. A connecting seat 403 is rotatably connected to the end of the connecting rod 404 away from the threaded block 402. A rotating rod 405 is installed inside the connecting seat 403. The positioning frame 406 is installed on the circumferential surface of the rotating rod 405 and is located around the material tray 205.

[0017] In practical application, this embodiment of the invention controls the movement of the equipment via the drive wheel set 101, causing the lifting frame 204 to be inserted under the material tray 205. Then, the lifting seat 203 is controlled to move upwards within the mounting frame 201. The lifting seat 203 drives the lifting frame 204 and the material tray 205 to their uppermost limit position. The equipment is then moved to the side of the material conveying equipment. At this point, the material box is transferred to the material tray 205 via the material handling mechanism 3. After the material tray 205 is filled with a layer of material boxes, the bidirectional lead screw 401 is controlled to rotate. The bidirectional lead screw 401 drives the threaded blocks 402 in each set to approach each other. The threaded blocks 402, through the connecting rod 404, drive the connecting seat 403 away from the support column 102, causing the surrounding positioning frames 406 to move inwards simultaneously, compressing the material boxes on the material tray 205. The material boxes on the tray 205 are tightly fitted together. Then, the bidirectional lead screw 401 is reversed, which drives the positioning frame 406 to move around to complete the reset. The lifting seat 203 is also controlled to descend, which drives the tray 205 and the material boxes to descend synchronously. At this time, the highest surface of the material box is the same as the initial highest surface of the tray 205, ensuring that the material boxes are placed at the same height. Subsequently, the material boxes can be stacked on the material boxes of the lower layer through the picking mechanism 3. After each layer is full, the positioning frame 406 is used to tightly fit the material boxes of each layer together. The multi-layer tight stacking can form a stable integrated structure, which greatly reduces the risk of the stack tilting and collapsing due to the center of gravity shift, equipment vibration or external impact, ensuring the safety of cargo transportation. At the same time, it can increase the cargo volume of a single transport and improve the efficiency of cargo transshipment. After the goods are stacked, the equipment is moved to the unloading position by controlling the drive wheel set 101. Then, the lifting seat 203 is lowered to the lowest limit position. At this time, the lifting frame 204 can be released from the support of the material tray 205, and the material tray 205 falls to the ground. The equipment is then moved to pull the lifting frame 204 out from under the material tray 205, thus completing the rapid unloading effect. Subsequently, new material trays 205 can be inserted and picked up by the lifting frame 204 to continue the transportation of subsequent goods.

[0018] In one embodiment of the present invention, positioning frames 406 of different shapes can be replaced according to the overall external dimensions of the cargo boxes after they are placed, so that when the replaced positioning frames 406 move inward to push the cargo boxes, they match the overall external dimensions of the cargo boxes after they are placed.

[0019] like Figure 10 and 11 As shown, in one embodiment, a lifting screw 206 is rotatably connected inside the mounting frame 201, the lifting seat 203 is threadedly connected to the lifting screw 206, and the output end of the servo motor 207 mounted on the upper end of the mounting frame 201 is fixedly connected to the lifting screw 206.

[0020] In practical applications, the embodiments of the present invention control the operation of the servo motor 207, which drives the lifting screw 206 to rotate. When the lifting screw 206 rotates, it drives the lifting seat 203 to rise or fall within the mounting frame 201, which can synchronously drive the material tray 205 and the goods to rise and fall, facilitating the stacking and unloading of goods.

[0021] like Figure 12 and 13 As shown, in one embodiment, a drive motor 407 is installed on the upper end of the upper frame 103, and a drive shaft 408 is installed on the output end of the drive motor 407. The drive shaft 408 is connected to the bidirectional lead screw 401 through a first sprocket set 409, and the bidirectional lead screws 401 are connected to each other through a second sprocket set 4010.

[0022] In practical application, the embodiments of the present invention control the operation of the drive motor 407, which drives the drive shaft 408 to rotate. The drive shaft 408 drives the bidirectional lead screw 401 to rotate through the first sprocket group 409. At the same time, through the action of the second sprocket group 4010, multiple bidirectional lead screws 401 rotate synchronously, thereby achieving the effect of simultaneously controlling the positioning frame 406 to move inward, pushing each layer of material boxes to fit tightly, so that the stacked material boxes can form a stable integrated structure and improve the stability of the material box stack.

[0023] like Figure 1-4 As shown, in one embodiment, the material handling mechanism 3 includes a support frame 301, a guide shaft 302, a suspension frame 303, a slide rail 304, a slider 3016, a mounting shell 306, and a suction cup 309. The support frame 301 is mounted on the upper end of the upper frame 103. Multiple guide shafts 302 are mounted inside the support frame 301. The suspension frame 303 is slidably connected to the circumferential surface of the guide shafts 302. The slide rail 304 is mounted on the lower end of the suspension frame 303. The slider 3016 is slidably connected inside the slide rail 304. A multi-stage electric telescopic rod 305 is mounted on the upper end of the slider 3016. The mounting shell 306 is mounted on the output end of the multi-stage electric telescopic rod 305. A rotary motor 307 is mounted inside the mounting shell 306. A connecting shaft 308 is mounted on the output end of the rotary motor 307. The suction cup 309 is mounted on the lower end of the connecting shaft 308.

[0024] In practical application, when the device moves to the material conveying equipment, the slider 3016 is controlled to move within the slide rail 304, causing the suction cup 309 to move onto the material box. Then, the output end of the multi-stage electric telescopic rod 305 extends, causing the suction cup 309 to descend and adhere to the material box. The output end of the multi-stage electric telescopic rod 305 then retracts, and the suction force of the suction cup 309 causes the material box to move upwards. Finally, the slider 3016 is again controlled to move within the slide rail 304, moving the material box to the material tray 2. Above 05, the front and rear positions of the material box can be changed, and the suspension frame 303 can be controlled to slide on the circumferential surface of the guide shaft 302 to adjust the left and right positions of the material box. At the same time, the rotation motor 307 can be controlled to rotate. The rotation motor 307 drives the suction cup 309 and the material box to rotate through the connecting shaft 308, and the placement angle of the material box can be adjusted. The material boxes can be neatly placed on the material tray 205. When the material tray 205 is full of material boxes, the sorting mechanism 4 can be used to tightly fit the material boxes between each layer, ensuring the stability of subsequent material box stacking.

[0025] like Figure 3 and 4 As shown, in one embodiment, a horizontal motor 3010 is mounted on the surface of the support frame 301, and a first threaded rod 3011 is mounted on the output end of the horizontal motor 3010. The suspension frame 303 is threadedly connected to the first threaded rod 3011. A vertical motor 3012 is mounted on the surface of the slide rail 304, and a rotating shaft 3013 is mounted on the output end of the vertical motor 3012. A second threaded rod 3014 rotatably connected inside the slide rail 304 is threadedly connected to the slider 3016. The rotating shaft 3013 and the second threaded rod 3014 are connected by a third sprocket set 3015.

[0026] In practical application, this invention controls the operation of the horizontal motor 3010, which drives the first threaded rod 3011 to rotate, thereby moving the suspension frame 303 left and right to adjust the left and right position of the material box. The vertical motor 3012 is controlled to rotate, which drives the rotating shaft 3013 to rotate. The rotating shaft 3013 drives the second threaded rod 3014 to rotate through the action of the third sprocket set 3015. The second threaded rod 3014 drives the slider 3016 to slide back and forth in the slide rail 304, thereby controlling the suction cup 309 to move back and forth to complete the material picking effect. At the same time, the front and back positions of the material box can be adjusted so that the material box can be stacked on the material tray 205.

[0027] like Figure 8 and 9As shown, in one embodiment, a sliding shaft 5 is slidably connected inside the connecting seat 403, a rack 501 is mounted on the circumferential surface of the sliding shaft 5, a gear 4011 mounted on the circumferential surface of the rotating rod 405 meshes with the rack 501, and a first spring 502 is installed between the sliding shaft 5 and the connecting seat 403.

[0028] In practical application, the first spring 502 pushes the sliding shaft 5 upward to its limit position. The sliding shaft 5 drives the rack 501 upward to its limit position. The rack 501 restricts the gear 4011, preventing the gear 4011 and the rotating rod 405 from rotating. This restricts the position of the positioning frame 406, allowing it to push the material boxes of each layer to fit tightly together. When the material tray 205 is supported on the ground, the sliding shaft 5 is pushed downward, simultaneously driving the rack 501 downward. The rack 501 drives the gear 4011 and the rotating rod 405 to rotate. The rotating rod 405 drives the positioning frame 406 to rotate upward, causing the rotating rod 405 to move away from the front of the goods pile. The subsequent control equipment moves backward, allowing the material tray 205 and the goods pile to separate from the equipment, achieving the effect of rapid unloading.

[0029] like Figure 7 , 13 As shown in 14 and 15, in one embodiment, a slide block 503 is mounted on the surface of the support column 102, a slide frame 504 is slidably connected to the slide block 503 and the lower frame 1, a second spring 505 is installed between the slide frame 504 and the lower frame 1, and pressure blocks 506 are mounted on the circumferential surface of the slide frame 504, and the pressure blocks 506 are in contact with the upper end of the slide shaft 5.

[0030] In practical application, the second spring 505 pushes the sliding frame 504 upward through the action of the second spring 505. The pressure block 506 installed on the circumferential surface of the sliding frame 504 fits against the slide base 503, so that the sliding frame 504 is in the uppermost extreme position. When the sliding frame 504 is pressed down, the sliding frame 504 presses down the sliding shaft 5 through the pressure block 506. The sliding shaft 5 drives the rack 501 to move synchronously, thereby achieving the effect of driving the positioning frame 406 to rotate.

[0031] like Figure 16 and 17 As shown, in one embodiment, a pressing arm 507 is mounted on the surface of the lifting seat 203, and the pressing arm 507 is used to press down the sliding frame 504.

[0032] In practical application, when the lifting seat 203 descends, it can simultaneously drive the lowering arm 507 to move. When the lifting seat 203 is about to descend to its lowest limit position, the lowering arm 507 will engage with the sliding frame 504. Subsequently, as the lifting seat 203 continues to descend, the lowering arm 507 can descend synchronously, pressing down on the sliding frame 504, causing the sliding frame 504 and the pressure block 506 to descend, pushing the sliding shaft 5 and the rack 501 to descend, thereby achieving the effect of controlling the rotation of the positioning frame 406, moving it away from the front of the goods stack, and facilitating the unloading of goods.
