Specific embodiments

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1. A bagged material transfer system, the structure is as Figures 1-9As shown, it includes a loader 13, a track 14 is arranged below the loader 13, a transfer vehicle 15 is arranged on the track 14; a crane device 16 is arranged above the track 14 and beside the loader 13; the transfer vehicle 15 includes a mobile vehicle 1 arranged on the track 14, a base 2 is arranged on the mobile vehicle 1, and two outer guard plates 3 are installed on the base 2. Among them, the specific individual components or devices such as the loader 13, the track 14, the mobile vehicle 1, etc. are directly purchased or welded and assembled according to the structure shown in the figure using existing accessories and existing technologies during specific implementation. For example, the loading machine 13 may adopt the device of Patent No. 2019101196680, 2022102266076 or 2021111145593 (it may further adopt the technology of Patent No. 2023211914858, 2023211918168, 202321192164X, 2023211924563, 2023217641623 and / or 2023218622102), these loading machines feed by belts and pass through transverse The shifting mechanism and the bag dropper can automatically complete the fixed-point and quantitative feeding of bagged materials; the bottom of the mobile vehicle 1 is provided with a roller driven by a motor and matched with the track 14; the base 2 is a structure composed of the outer column bottom plate, the triangular plate reinforcement plate, the bolt assembly, etc.; the outer guard plate 3 is a structure composed of the side plate, the reinforcement ribs, the column, the cross beam, etc.; the traveling crane device 16 includes a mounting beam assembly 17, and a crane 18 is movably arranged on the mounting beam assembly 17, and the crane 18 is connected to the hook 20 through a lifting rope 19; the control system adopted is also the existing device or conventional.

[0033] When the above system is implemented, Figure 1Taking the shown state and angle as an example, the remote-controlled overhead crane device 16 lifts and removes the loaded ton bags, and transports the ton bags to a predetermined position. A new ton bag is laid on the lifting platform 4 between the two outer guard plates 3 of the transfer vehicle 15. The mobile vehicle 1 is started to move leftward to the lower part of the loading machine 13. The loading machine 13 automatically feeds the materials, and the materials are stacked on the ton bag. The stacking method can be carried out in a conventional manner according to the specifications of the ton bag. Generally, the ton bags used are 1-ton bags or 2-ton bags. In this example, 1-ton bags filled with 50 kg / bag of material are used, and they are stacked in a way of 4 bags per layer and a total of 5 layers. After stacking, the mobile vehicle 1 moves rightward along the track 14 to the lower part of the overhead crane device 16, and is lifted from both ends of the ton bag by the overhead crane device 16. The ton bag material package is transported to a predetermined position. Taking the illustration as an example, the feeding direction is "inward or outward direction in the illustration" perpendicular to the movement direction of the trolley. The predetermined position can be the cargo box of a truck, that is, the overhead crane device 16 directly sends the ton bag material package to the designated position in the cargo box; the predetermined position can also be the transfer position in the material temporary storage area. After repeating the above steps and temporarily storing a large number of ton bags at the transfer position, a truck is driven over to centrally lift the ton bag material packages into the cargo box. After the above method uses ton bags for material transportation and loading, when the truck arrives at the destination for unloading, it also unloads the goods in the form of ton bags. Unloading one ton bag unloads 20 bags of materials accordingly, and the overall unloading efficiency is greatly improved. Moreover, the used ton bags can be collected and reused, without additional costs.

[0034] Furthermore, it is implemented with the following specific structure:

[0035] A lifting platform 4 is provided between the two outer guard plates 3. The lifting platform 4 is provided with a top platform as shown in the illustration. A liftable support is provided below the platform. The lifting power preferably uses a hydraulic cylinder, and the height of the platform can be freely adjusted through the hydraulic cylinder.

[0036] An intermediate guard plate 7 is provided between the two outer guard plates 3, and a lifting platform 4 is respectively provided between adjacent plates. Adjacent plates refer to the two adjacent plates of the outer guard plate 3 and the intermediate guard plate 7.

[0037] Flanging frames 5 are respectively rotatably installed at the front and rear ends of the top of the lifting platform 4; guide rods 6 are respectively horizontally arranged on the front and rear sides of the outer guard plate 3; the flanging frames 5 are correspondingly and one-to-one horizontally placed on the guide rods 6 front and back. The flanging frame 5 is composed of a long side, a short side, a hypotenuse, a beam, etc. according to the illustrated structure.

[0038] When the lifting platform 4 rises to the highest position, the flanging frame 5 is horizontally arranged, which is the initial state of the transfer vehicle 15. A guide rod sleeve is arranged outside the guide rod 6. When the lifting platform 4 descends, the guide rod sleeve can rotate on the guide rod 6 to facilitate the movement of the flanging frame 5. During the process, the flanging frames 5 at both ends lift the ton bag upwards to facilitate the loading of the ton bag. The ton bag hanging ears at both ends of the ton bag can also be temporarily tied and fixed through the flanging frame 5 to prevent the ton bag hanging ears from accidentally being pressed into the bottom of the ton bag, which is not conducive to lifting.

[0039] Both ends of the guide rod 6 are arranged on the pull rod seat 11, and the pull rod seat 11 is connected to the outer guard plate 3. The pull rod seat 11 is used to install and support the guide rod 6.

[0040] Multiple platform lower limit rods 9 are connected to the top of the mobile vehicle 1. The lifting platform 4 is equipped with upper limit and lower limit travel switches. The upper limit position is preferably 1500 mm away from the track, and the lower limit position is the position of the height difference between the upper limit position of the track and the total height of the material. The platform lower limit rod 9 plays a role in protecting and supporting when the lower limit switch fails.

[0041] The flanging frame 5 and the lifting platform 4 are connected by hinges. The hinges provide the rotatability between the flanging frame 5 and the lifting platform 4.

[0042] Ground inspection brackets 8 are arranged on the front and back sides of the mobile vehicle 1. The ground inspection brackets 8 are welded according to the positions of the travel switches and control switches, and the switches are used to control the moving position of the mobile vehicle 1.

[0043] When the above device is executed, refer to Figure 5 , during the loading process of this system, when bagging is carried out into the ton bag, the initial state of the transfer vehicle 15 is as Figure 5As shown, the height of the middle guard plate 7 and the outer guard plate 3 exceeds the lifting platform 4 by a certain distance, which can be a height slightly higher than the thickness of the material bag, such as 20 cm; the middle guard plate 7 and the outer guard plate 3 are provided with inclined surfaces, which are used to guide the material bag to maintain its posture and accurately fall on the predetermined position of the ton bag; the height of the lifting platform 4 from the bag dropping device is the optimal height for the material bag to maintain its posture after dropping the bag, such as 60 cm; the loading machine 13 throws the bags into the ton bag layer by layer. After the first layer is loaded, control the lifting platform 4 to descend by the height of one layer of the material bag, such as 15 cm. At this time, the flanging frame 5 is tilted inward under the action of the guide rod 6 and pulls the end of the ton bag. After the first layer is loaded, load another layer of the material bag in the same way. At this time, since the lifting platform 4 has descended by the height of one layer of the material bag, the height from the top of the first layer of the material bag to the bag dropping device still remains at the optimal bag throwing height, and the inward-tilted flanging frame 5 cooperates with the tops of the middle guard plate 7 and the outer guard plate 3 to form a shape similar to a funnel, which can further ensure the accuracy of bag dropping and avoid bag slipping. After the second layer of the material bag is loaded, the lifting platform 4 descends another 15 cm, and repeat the above steps to continue throwing the bags at the optimal height. After the ton bag is filled with the material bag, start the mobile vehicle 1, move the bag loading and transporting vehicle 15 under the double-row crane system 16, manually loosen the two ends of the hanging ears of the ton bag and perform bundling and pre-tightening, and hang the corresponding hanging ears at both ends of the ton bag on the hooks 25. When the ton bag is lifted, tighten the binding belt by the way to carry out hoisting and loading. It should also be noted that each of the two lifting platforms 4 has a hydraulic cylinder. If the two cylinders have independent control systems, they can be controlled separately. When implementing this system, in the preferred cost-saving way, the two hydraulic cylinders share a single oil pump and a single hydraulic station. Under this facility, the pressures of the two hydraulic cylinders are synchronized. Therefore, this system proposes an adapted bag throwing method. When the loading machine 13 throws the bags onto the two lifting platforms of a transporting vehicle 15, it is preferred to throw 1 layer of the material bag into the first ton bag first, then throw 2 layers of the material bag into the second ton bag, then throw 2 layers into the first ton bag, and then alternate in the way of 2 layers until after the last layer of the material bag is loaded, the material bags in both ton bags reach the required number of layers and the bag throwing is completed. The purpose of such bag throwing is to ensure the balance of the transporting vehicle 15 and the stability of the two lifting platforms 4. If the bags are loaded into one ton bag first and then into the other ton bag in the conventional way, there will be problems such as more than 1 ton of weight pressing on one side of the transporting vehicle 15 when the first ton bag is full, no weight on the other side of the transporting vehicle 15, the overall device is under unbalanced pressure, and the components are prone to damage.

[0044] It is not convenient to lift two packages of ton bags simultaneously with the conventional hook 20 of the overhead crane device 16. Therefore, a conversion piece 21 is provided. The middle of the conversion piece 21 is hung on the hook 20. Hanging ears 22 are connected to both ends of the conversion piece 21. Hanging holes 23 are respectively arranged at both ends of the hanging ears 22. Chains 24 are connected to the hanging holes 23, and hooks 25 are connected to the chains 24. With this structure, each of the four hanging holes 23 of the hanging ears 22 is connected to a hook 25 through a chain 24. The four hooks 25 are grouped in pairs of two and respectively hang on the four ends of the two packages of ton bags, that is, the four ton bag hanging ears, so as to realize the operation of lifting two packages of ton bags at one time.

[0045] To facilitate the use of this system, preferably, the remote control device of the overhead crane device 16 is arranged on the transfer vehicle 15. The remote control device includes three control buttons respectively for controlling the overhead crane to rise, fall, and move horizontally, and can realize the function of moving the ton bag to the designated transfer position.

[0046] Embodiment 2. A bagged material transfer system. This embodiment is based on Embodiment 1, and the difference is that the middle guard plate 7 is not provided in this embodiment. By adjusting the fixing positions of the illustrated bolts, the two outer guard plates 3 are moved inward by a certain distance so that the distance between the two outer guard plates 3 is just enough for two ton bags. To enable the two outer guard plates 3 to move inward by a certain distance smoothly, a limited-length sleeve 10 is also sleeved on the corresponding guide rod 6. The limited-length sleeve 10 can rotate on the guide rod 6, and the length of the limited-length sleeve 10 is just the thickness of the middle guard plate 7 and the distance that the two outer guard plates 3 are adjusted towards the center. In this way, when the two outer guard plates 3 need to move towards the center, removing the limited-length sleeve 10 can avoid the blockage of the guide rod sleeve.

[0047] In this embodiment, conventional hook operations are adopted, and the charging, lifting of ton bags, and feeding are carried out in the manner of a single 2-ton bag.

[0048] Embodiment 3. A bagged material transfer system. This embodiment is based on Embodiment 1, and the difference is that 2 middle guard plates 7 are provided, and correspondingly, 3 lifting platforms 4 are also provided. In this embodiment, the charging, lifting of ton bags, and feeding are carried out in the manner of 3 ton bags, and correspondingly, 1 more hanging ear 22 is added.

[0049] Embodiment 4. A bagged material transfer system. This embodiment is based on Embodiment 1, and the difference is that the hydraulic system is not used for the lifting of the platform, but the servo electric push rod is used.

[0050] Embodiment 5. A bulk bag transfer system. The overhead crane device 16 in Embodiment 1 lifts the bulk bag material package from the lifting platform 4 and suspends it to the designated transfer position. After unloading the bulk bag material package, the overhead crane device 16 returns to the transfer position of the transfer vehicle with one key. This embodiment is based on Embodiment 1, and another overhead crane device A is added at the transfer position. When the overhead crane device 16 places the bulk bag material package at the transfer position, the overhead crane device A hoists the bulk bag material package from the transfer position onto the transport vehicle.

[0051] Embodiment 6. A bulk bag transfer system. The overhead crane device 16 in Embodiment 1 lifts the bulk bag material package from the lifting platform 4 and suspends it to the carriage. In this embodiment, another overhead crane device B and a transfer vehicle are added on the track 14. When the original overhead crane device 16 transports the bulk bag material package out, another transfer vehicle travels to the loading machine 13 for loading and is hoisted to the carriage by the overhead crane device B. At this time, the original transfer vehicle and the overhead crane device 16 return. That is, in this embodiment, through the combination of two sets of transfer vehicles and overhead crane devices, continuous loading and feeding are carried out alternately back and forth, thereby further improving the bulk bag transfer efficiency.

[0052] Embodiment 7. A bulk bag transfer system. This embodiment is similar to Embodiment 1, except that when this embodiment is implemented, pallets are used instead of bulk bags, and the pallets can adopt conventional structures.

[0053] Furthermore, it is preferable to use a pallet similar to the structure of a vegetable transfer box, which is convenient for stacking the pallets on the carriage.
