Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to an automatic unloading mechanism for a warehouse used for logistics distribution. Background Art

[0002] With the continuous development of the Internet and e-commerce, the logistics industry has developed rapidly. Logistics distribution is an important link in in-transit logistics operations and a node connecting upstream and downstream in a multi-level supply chain. The smoothness of its operation is directly related to the smoothness of the operation of the entire supply chain. It has functions such as sorting, storage, distribution, connection and processing. In daily work, the number of logistics items is huge, and it even reaches a very high order of magnitude during specific shopping festivals. The staff needs to enter the information, and then divert it according to the information, and then identify and sort it according to the information, and distribute the goods in parts. After the sorting is completed, another gun scan is carried out to match the specific address of the recipient with the specific route of the express delivery, and the workload when the goods are unloaded in the warehouse is very large.

[0003] When unloading goods from a cargo truck, traditional logistics distribution warehouses generally use manual labor to unload the goods over long distances and transport them to the cargo conveying mechanism in the warehouse. Manual unloading is time-consuming and labor-intensive, with high labor costs. In addition, it is often necessary to manually perform the initial sorting of the logistics goods according to the size of the logistics goods. Some existing unloading mechanisms are only unloading platforms, lacking a shock-absorbing lifting mechanism, and also lacking the transmission function and initial sorting function that can reduce manpower. For this reason, we have proposed an automatic unloading mechanism for logistics distribution warehouses to solve the above problems. Summary of the invention

The rubber airbag makes the third rubber airbag expand and stretch rapidly and lift the end of the unloading plate to compress and deflect toward one end of the spring through the rotating shaft, so that the other end of the unloading plate is in contact with the receiving plate. At this time, the goods on the unloading plate can be automatically unloaded and slide onto the conveyor belt. The receiving plate plays the role of receiving the unloading plate to prevent the unloading plate from excessive deflection and contact with the conveyor belt. The third rubber airbag can also prevent the unloading plate from high-strength collision with the support column, which is beneficial to prolonging the service life. There is no need to manually unload the goods and carry them to the conveyor belt, which saves time and effort, reduces labor intensity, reduces labor costs, and improves efficiency.

[0019] 3. By arranging a conveyor belt, a second side plate, a top plate, a first electric cylinder, an adjustable baffle, a push plate, a second electric cylinder and a distribution slide, as the conveyor belt is conveyed, the goods can be driven to move toward the goods conveying mechanism in the cargo warehouse, and the first electric cylinder can drive the adjustable baffle to rise and fall, so as to adjust the gap between the adjustable baffle and the conveyor belt. The gap can be adjusted and set as needed, so that some small-packaged goods can be directly conveyed to the goods conveying mechanism in the cargo warehouse through the gap through the adjustable baffle by the conveyor belt, and the goods blocked by the adjustable baffle are larger packages. The second electric cylinder can drive the push plate in front of the adjustable baffle to move horizontally, and push the larger-packaged goods blocked in front of the adjustable baffle away from the conveyor belt through the opening, so that the larger-packaged goods slide to the goods conveying mechanism in another warehouse through the distribution slide at the opening, which can save the labor of manually performing the initial sorting of the logistics goods at the warehouse entrance, save time and effort, reduce labor costs and improve efficiency.

[0028] Among them, the width of the conveyor belt 10 is larger than the width of the unloading plate 4. Two mutually symmetrical first side plates 41 are fixedly connected to the upper side wall of the unloading plate 4. The two first side plates 41 are respectively arranged on both sides of the unloading plate 4. Two brackets 5 are fixedly connected to the upper side wall of the distribution platform 1. A support column 7 and a spring 8 are respectively arranged on the left and right sides of the bracket 5. The lower side wall of the support column 7 is fixedly connected to the upper side wall of the distribution platform 1. The upper and lower ends of the spring 8 are respectively fixedly connected to the lower side wall of the unloading plate 4 and the upper side wall of the distribution platform 1. The side wall of the unloading plate 4 close to one end of the support column 7 is rotatably connected to the two brackets 5 through a rotating shaft 6. A third rubber airbag 71 is embedded on the upper side wall of the support column 7. The upper side wall of the support column 7 is provided with a third rubber airbag 7 for placing the third rubber airbag 7. 1, the upper and lower side walls of the third rubber airbag 71 are respectively fixedly connected to the lower side wall of the unloading plate 4 and the bottom wall of the second groove, a second air pump 72 is fixedly connected to the side wall of the support column 7, the output end of the second air pump 72 passes through the side wall of the support column 7 and is connected to the third rubber airbag 71, and a second electric exhaust valve is provided on the side wall of the third rubber airbag 71. Second side plates 9 are provided on both sides of the conveyor belt 10, and a receiving plate 11 is provided at one end of the second side plate 9 close to the unloading plate 4. The receiving plate 11 is arranged above the end of the conveyor belt 10, and the side walls of the receiving plate 11 on both sides are respectively fixedly connected to the side walls opposite to the two second side plates 9, and the lower end side walls of the two second side plates 9 are fixedly connected to the upper end side wall of the distribution platform 1. By setting the unloading plate 4 and the first The side panels 41, the brackets 5, the rotating shafts 6, the supporting pillars 7, the third rubber airbags 71, the second air pumps 72, the springs 8, the second side panels 9, the conveyor belts 10 and the receiving plates 11 are provided with the unloading plate 4 having two first side panels 41 for temporarily placing goods and allowing the goods to slide along the first side panels 41 to the conveyor belts 10. The conveyor belts 10 are used to transport the goods that slide down thereon to the goods transporting mechanism in the cargo warehouse connected thereto. When the unloading plate 4 and the unloading cargo bucket are lifted and lowered to be flush with each other by the lifting mechanism 3, the unloading plate 4 is supported by the brackets 5 at this time, and the supporting pillars 7 and the springs 8 are provided at both ends to maintain balance. The goods in the unloading cargo bucket can be dropped onto the unloading plate 4 by the staff, or the goods can be dumped onto the unloading plate 4 by controlling the tilt of the unloading cargo bucket. The shafts 6 are all arranged on the side wall of the unloading plate 4 close to the end of the support column 7 rather than at the axis of the unloading plate 4. Therefore, as the goods on the unloading plate 4 increase, the unloading plate 4 can be compressed and deflected toward one end of the spring 8 through the rotating shaft 6. At the same time, it can also cooperate with the support column 7 to control the start of the second air pump 72. The second air pump 72 can quickly pump gas into the third rubber airbag 71, so that the third rubber airbag 71 can quickly expand and stretch and lift the end of the unloading plate 4 to be compressed and deflected toward one end of the spring 8 through the rotating shaft 6, so that the other end of the unloading plate 4 is in contact with the receiving plate 11.

Similarly,By closing the second air pump 72 and controlling the second electric exhaust valve to open, the gas in the third rubber airbag 71 can be quickly discharged under the gravity of the unloading plate 4 and the elastic recovery of the spring 8, so that the unloading plate 4 can be deflected and restored to a horizontal state for the next unloading. The third rubber airbag 71 can also prevent the unloading plate 4 from hitting the support column 7 with high strength, which is beneficial to prolonging the service life. There is no need to manually unload and transport the goods to the conveyor belt 10, which saves time and effort, reduces labor intensity, reduces labor costs, and improves efficiency.

[0029] Among them, the upper end side walls of the two second side plates 9 away from the unloading plate 4 are commonly fixedly connected with a top plate 12, and the upper end side walls of the top plate 12 are fixedly connected with two first electric cylinders 13, and the ends of the output shafts of the two first electric cylinders 13 penetrate the upper end side walls of the top plate 12 and are fixedly connected with an adjustable baffle 14, and the side of the adjustable baffle 14 close to the unloading plate 4 is provided with a push plate 15, and the side wall of the second side plate 9 is fixedly connected with a second electric cylinder 16, and the end of the output shaft of the second electric cylinder 16 penetrates the side wall of the second side plate 9 and is connected with the push plate The side wall of the second side plate 9 is fixedly connected, the side wall of the second side plate 9 is penetrated with an opening corresponding to the position of the push plate 15, and the side wall of the second side plate 9 located at the opening is fixedly connected with a distribution slide 17. By arranging the conveyor belt 10, the second side plate 9, the top plate 12, the first electric cylinder 13, the adjustable baffle 14, the push plate 15, the second electric cylinder 16 and the distribution slide 17, when the goods are automatically unloaded onto the conveyor belt 10, along with the transmission of the conveyor belt 10, the goods can be driven to move toward the goods conveying mechanism in the warehouse. In this process, The first electric cylinder 13 is controlled to be started, and the first electric cylinder 13 can drive the adjustable baffle 14 to rise and fall, so as to adjust the gap between the adjustable baffle 14 and the conveyor belt 10. Goods are generally divided into flat pieces and parcels. Flat pieces are generally small packages, and parcels are generally larger packages. The gap can be adjusted and set according to the size and demand of flat pieces and parcels, so that some small-packaged goods can be directly conveyed to the goods conveying mechanism in the warehouse by the conveyor belt 10 through the gap through the adjustable baffle 14, while the goods blocked by the adjustable baffle 14 are larger packages. At this time, the second electric cylinder 16 is controlled to be started, and the second electric cylinder 16 can drive the push plate 15 in front of the adjustable baffle 14 to move horizontally, and push the larger-packaged goods blocked in front of the adjustable baffle 14 away from the conveyor belt 10 through the opening, so that the larger-packaged goods slide to the goods conveying mechanism in another warehouse through the distribution slide 17 at the opening, which can save the labor of manually sorting the logistics goods at the warehouse entrance, save time and labor, reduce labor costs, and improve efficiency.

First, the height is adjusted by the lifting mechanism 3 so that the unloading plate 4 and the unloading cargo bucket are flush with each other. The first electric exhaust valve 39 can be an electromagnetic valve, which controls the first electric exhaust valve 39 to be closed, and controls the start of the first air pump 37, so that gas can be quickly input into the first rubber airbag 34. At the same time, the air in the first rubber airbag 34 The liquid is continuously injected into the second rubber airbag 35 through the connecting pipe 38, so that the first rubber airbag 34 and the second rubber airbag 35 expand and stretch rapidly, the first rubber airbag 34 lifts the distribution platform 1, and the second rubber airbag 35 lifts the slider 33 together with the guide column 32, so that the guide column 32 slides and lifts upward along the first guide groove 31, so that the unloading plate 4 and the unloading cargo bucket are flush with each other. At this time, the unloading plate 4 is supported by the bracket 5, and the two ends are also provided with support columns 7 and springs 8 to maintain balance. The goods in the unloading cargo bucket can be put onto the unloading plate 4 by the staff, or the goods can be dumped onto the unloading plate 4 by controlling the tilt of the unloading cargo bucket. As the goods on the unloading plate 4 increase, the unloading plate 4 can be made to pass The rotating shaft 6 is compressed and deflected toward one end of the spring 8, and at the same time, it can cooperate with the support column 7 to control the start of the second air pump 72. The second air pump 72 can quickly pump gas into the third rubber airbag 71, so that the third rubber airbag 71 can quickly expand and stretch and lift the end of the unloading plate 4 through the rotating shaft 6. The compression and deflection toward one end of the spring 8 makes the other end of the unloading plate 4 contact with the receiving plate 11. At this time, the goods on the unloading plate 4 can be automatically unloaded and slide onto the conveyor belt 10. When the goods are automatically unloaded onto the conveyor belt 10, as the conveyor belt 10 is transported, it can drive the goods to move toward the goods conveying mechanism in the warehouse. In this process, the first electric cylinder 13 is controlled to start, and the first electric cylinder 13 can drive the adjustable baffle 14 to rise and fall. The gap between the adjustable baffle 14 and the conveyor belt 10 can be adjusted as needed, so that some small-packaged goods can be directly conveyed to the cargo conveying mechanism in the warehouse through the adjustable baffle 14 through the gap by the conveyor belt 10, while the goods in larger packages are blocked by the adjustable baffle 14. At this time, the second electric cylinder 16 is controlled to start, and the second electric cylinder 16 can drive the push plate 15 in front of the adjustable baffle 14 to move horizontally, and push the larger-packaged goods blocked in front of the adjustable baffle 14 away from the conveyor belt 10 through the opening, so that the larger-packaged goods slide through the distribution slide 17 at the opening to the cargo conveying mechanism in another warehouse, which can save the labor of manually sorting the logistics goods at the warehouse entrance.
