[0002] In the process of logistics transportation, bulk bags, as a large-capacity packaging container, are widely used in the loading and transfer of various bulk materials. Traditional bulk bag loading relies on manual operation. Workers need to manually connect the hook of a crane or forklift to the handle of the bulk bag and then carry out hoisting and loading. This method not only has a high labor intensity and low efficiency, but also has certain safety risks. The crane hoists the bulk bag to the truck for lifting and then loading. The hoisting distance is long, and the large weight of the bulk bag makes the hoisting process slow. The long-distance round trip of the crane seriously restricts the improvement of the bulk bag loading efficiency. Content of the Utility Model

[0029] The present utility model will be further described in detail below in conjunction with the accompanying drawings. The accompanying drawings illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0030] Specific embodiment 1 of the ton-bag loading center-lifting type conveyor line provided by the present utility model:

[0031] Please refer to Figures 1-7 , the ton-bag loading center-lifting type conveyor line includes a loading platform 1, a first conveyor 2, a second conveyor 5 and a lifting conveyor 3.

[0032] In this embodiment, two second conveyors 5 are provided, both of which are relatively long belt conveyors. The two second conveyors 5 are corresponding end to end; the two second conveyors 5 convey the ton-bags formed by bagging and packing alkali salts to near the truck. In some other embodiments, the second conveyor 5 includes multiple conveyors to realize the transfer of ton-bags closer to the truck.

[0033] As Figure 6 and Figure 7 shown, the loading system includes a steel structure frame, and the truck can enter and pass through the steel structure frame. A bridge crane is installed on the steel structure frame as a crane for ton-bag loading and stacking; the bridge crane is connected with a grasping device for grasping ton-bags.

[0034] During the loading process, the truck stands inside the steel structure frame. The loading platform 1 corresponds to the middle part of the truck bed, and the loading platform 1 is located inside the middle part of the steel structure frame.

[0035] The loading platform 1 includes a support platform, and legs are provided on the lower side of the support platform. The upper side height of the loading platform 1 is close to the upper side height of the truck bed.

[0036] The first conveyor 2 is installed on the upper side of the loading platform 1. The first conveyor 2 is a relatively short belt conveyor, and its length only needs to be greater than the length of the ton-bag. In this embodiment, the upper side height of the first conveyor 2 is not lower than the upper side height of the truck bed; the first conveyor 2 receives and temporarily supports the ton-bag, and waits for the crane to lift the ton-bag onto the truck for stacking.

[0037] Two first conveyors 2 are provided on the upper side of the loading platform 1, and the two first conveyors 2 are corresponding end to end. The two first conveyors 2 can receive and support two ton-bags.

[0038] The first conveyor 2 is a reversible belt conveyor, and the forward and reverse rotation of the belt is realized by the forward and reverse rotation of its motor. After the two first conveyors 2 support two ton bags, the first conveyor 2 with the forward and reverse rotation function can bring the two ton bags closer, and then the first conveyor 2 stops running; it is convenient for the grasping device to grasp the two ton bags at the same time.

[0039] The height of the second conveyor 5 is lower than that of the first conveyor 2, and it conveys the ton bag towards the direction of the first conveyor 2. In this embodiment, the second conveyor 5 is close to the ground.

[0040] The lifting conveyor 3 is vertically lifted between the first conveyor 2 and the second conveyor 5. The lifting conveyor 3 is a belt conveyor, and its length is slightly longer than the length of a ton bag, and it is used to accommodate a ton bag and lift the height of the ton bag.

[0041] There is a lift 6 between the first conveyor 2 and the second conveyor 5, and the lift 6 vertically lifts the lifting conveyor 3. The lift 6 includes a frame 61, a lifting platform 62 that supports the lifting conveyor 3, and a winch 63; the lifting platform 62 moves vertically along the frame 61; the lifting conveyor 3 is installed on the upper side of the lifting platform 62, and the winch 63 drives the lifting platform 62 to lift through a steel wire rope 64; in some embodiments, two winches 63 are provided and operate synchronously. The winch 63 includes a double drum, and two steel wire ropes 64 are wound on each double drum and are respectively connected to the upper sides of the two corners of the lifting platform 62. In some other embodiments, there are four synchronous winches 63 at the top of the lift 6, which are respectively connected to the upper sides of the four corners of the lifting platform 62 through steel wire ropes 64.

[0042] In this embodiment, the frame 61 includes four vertical angle steels, and the four corners of the lifting platform 62 are respectively located inside the four angle steels. The frame 61 enables the lifting platform 62 to lift inside the frame 61 and limits the lifting platform 62. In some embodiments, a number of vertical tracks are provided on the frame 61, and sliding seats that move vertically along the tracks are provided on the lifting platform 62. In some other embodiments, rollers are provided at the corners of the lifting platform 62, and the rollers move along the inside of the frame 61. It can make the lifting platform 62 lift vertically more stably.

[0043] When the lifting conveyor 3 is at a low position, its height is the same as that of the second conveyor 5, so as to facilitate receiving the conveyed ton bag from the second conveyor 5. When the lifting conveyor 3 is at a high position, its height is the same as that of the first conveyor 2, so as to facilitate conveying the lifted ton bag to the upper side of the first conveyor 2.

[0044] In this embodiment, a third conveyor 4 is provided between the second conveyor 5 and the lifting conveyor 3; the third conveyor 4 is a belt conveyor with the same length as the lifting conveyor 3. The third conveyor 4 is used to temporarily store the ton bags. After the ton bags move to the upper side of the third conveyor 4, the third conveyor 4 stops operating and waits until the lifting conveyor 3 is in the low position before operating again to convey the temporarily stored ton bags to the lifting conveyor 3.

[0045] In this embodiment, the lengths of the first conveyor 2, the lifting conveyor 3, and the third conveyor 4 are all less than that of the second conveyor 5. The height of the third conveyor 4 is the same as that of the second conveyor 5.

[0046] The third conveyor 4 compensates for the error in the cooperation between the conveyors, facilitating the efficient and orderly conveyance of the ton bags to the lifting conveyor 3. At the same time, it reduces the shutdown of the long-distance second conveyor 5, making the entire conveyor line stable and orderly, which is conducive to the full-line automation of ton bag loading onto the truck.

[0047] In this embodiment, as Figure 6 and Figure 7 shown, the conveying directions of the first conveyor 2, the second conveyor 5, the third conveyor 4, and the lifting conveyor 3 are all parallel to the length direction of the truck.

[0048] During the conveying process, the second conveyor 5 conveys the ton bags towards the middle of the truck. After the ton bags move to the upper side of the third conveyor 4, the third conveyor 4 stops operating. After the lifting conveyor 3 is in the low position, the lifting conveyor 3 and the third conveyor 4 operate, and the third conveyor 4 conveys the ton bags to the upper side of the lifting conveyor 3; after the lifting conveyor 3 receives the ton bags, it stops operating. After the lifting conveyor 3 rises to the high position, it operates again, and the first conveyor 2 operates in the direction away from the lifting conveyor 3 to convey the ton bags to the upper side of the first conveyor 2 away from the lifting conveyor 3, and the first conveyor 2 away from the lifting conveyor 3 stops operating. According to the above steps, another ton bag is conveyed to the upper side of the first conveyor 2 close to the lifting conveyor 3, so that there are ton bags on the upper sides of both first conveyors 2. Then, the first conveyor 2 away from the lifting conveyor 3 rotates in reverse, and the first conveyor 2 close to the lifting conveyor 3 rotates forward, bringing the two ton bags closer. Then, the first conveyor 2 stops operating and waits for the grasping device to grasp the two ton bags simultaneously.

[0049] Specific embodiment 2 of the ton bag loading center lifting type conveyor line provided by the present utility model:

[0050] Please refer to Figure 8 , the conveying directions of the first conveyor 2, the second conveyor 5, the third conveyor 4, and the lifting conveyor 3 are all perpendicular to the length direction of the truck; the main difference between this embodiment and Embodiment 1 lies in: the layout directions of the conveyors. By different layout directions of the conveyors, different site requirements can be adapted.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
