Description

Technical Field

[0001] This utility model relates to the field of transportation machinery technology, specifically a double-layer material transportation device. Background Technology

[0002] Granular materials, such as plastic granules, are generally transported in bags, and the efficiency and cost of this transportation directly impact the overall supply chain operation. Currently, the transportation of plastic granules typically employs the following traditional process: first, the plastic granules are bagged to form individual packages; then, the bagged plastic granules are transported to the truck bed via a conveyor; finally, workers manually stack the granules inside the truck bed to achieve orderly stacking, thereby improving the utilization rate of the truck bed space and the loading capacity.

[0003] However, the above methods have significant drawbacks: First, manual stacking is inefficient and heavily reliant on manual labor, resulting in a long overall transportation process that is difficult to meet the needs of large-scale transportation; second, workers have to perform high-intensity physical labor in cramped carriages, which not only creates a harsh working environment and poses significant safety hazards, but also makes them prone to fatigue, leading to unstable stacking and increasing the risk of cargo damage during transportation; third, traditional conveyors are ground-based mobile devices that require excessive space in the workshop when loading, thereby reducing the amount of plastic granules stored in the workshop and affecting transportation efficiency.

[0004] Therefore, there is a lack of existing technologies that can achieve automated, efficient, and low-labor-intensity plastic pellet loading and stacking solutions, and there is an urgent need to solve the above problems through technological innovation. Utility Model Content

[0008] The first conveyor is horizontally installed at the power output end of the linear conveyor;

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0035] This utility model discloses a double-layer material transport device, including a linear conveyor fixedly installed on the top of the workshop; its specific structure includes two parallel and symmetrically arranged H-beams 11, and a screw drive device for driving the first conveyor 2 to move linearly. The slots of the H-beams 11 are horizontally oriented, and their upper ends are fixedly connected to the top of the workshop. The screw drive device includes a horizontally arranged ball screw pair and a reduction motor fixedly connected to one end of the screw.

[0036] The belt-driven first conveyor 2 is horizontally arranged, and its frame is equipped with multiple rollers 21 on both sides that engage with the side grooves of the H-beams 11, allowing the first conveyor 2 to move directionally along the length of the H-beams 11. The frame of the first conveyor 2 is fixedly connected to the screw nut in the ball screw assembly. When the geared motor starts, it can drive the first conveyor 2 to move.

[0037] A second conveyor 3 is disposed below the first conveyor 2, and in vertical projection, the center lines of the first conveyor 2 and the second conveyor 3 in the length direction coincide.

[0038] by Figure 3From a reference perspective, the right end of the first conveyor 2 is the input end, and the left end is the output end; the left end of the second conveyor 3 is the input end, and the right end is the output end. The left end of the second conveyor 3 extends beyond the left end of the first conveyor 2, so that when material falls from the left end of the first conveyor 2, it can land stably on the left end of the second conveyor 3.

[0039] A rotating assembly 4 is also installed on the frame of the first conveyor 2 to drive the second conveyor 3 to rotate. Its specific structure includes a lifting cylinder 41 and a connecting rod 42. The cylinder body of the lifting cylinder 41 is hinged to the left side of the frame of the first conveyor 2, and the driving end of the lifting cylinder 41 faces downwards and is hinged to the left end of the frame of the second conveyor 3. The connecting rod 42 is located on the right side of the lifting cylinder 41, and its two ends are hinged to the first conveyor 2 and the second conveyor 3 respectively. With this configuration, when the lifting cylinder 41 is started, it can drive the second conveyor 3 to swing up and down, thereby adjusting the height of the right end of the second conveyor 3. Since the minimum drop height of the bagged plastic granules is 0.6m (height from the drop surface) and the maximum drop height is 1.2m, this is to ensure that the bagged plastic granules not only fall accurately to the target area but also do not break due to excessive impact. Therefore, by adjusting the height of the right end of the second conveyor 3, the drop height of the bagged plastic granules can be adjusted.

[0040] The tail end of the second conveyor 3 is equipped with an upward-curving retention platform 31, which is a non-powered roller conveyor 33. When the material moves to the retention platform 31, its kinetic potential energy decreases, and the impact force of falling is also reduced, thus preventing the bag from breaking. Moreover, under the action of the rotating component 4, when the material moves to the retention platform 31, the right end of the second conveyor 3 first rotates upward a certain distance, allowing the material to pause briefly on the DC platform to remove and eliminate the material's kinetic potential energy; then the right end of the second conveyor 3 rotates downward, and the material falls freely, thus minimizing the impact force of the falling material.

[0041] Because the material will shift in position when it falls onto the second conveyor 3, symmetrically arranged leveling plates 32 are installed on both sides of the middle position of the second conveyor 3. The leveling plates 32 limit the material and correct its position. The area of ​​the second conveyor 3 with the leveling plates 32 is the roller conveyor 33. This arrangement reduces the friction between the material and the roller conveyor 33, facilitating material movement and position correction.

[0042] Robotic arms 6 are installed on both sides of the lower end of the H-beam 11. The drive end of the robotic arm 6 is equipped with a gripper assembly 5, which is located on both the front and rear sides of the freight car, allowing it to cover the entire area of ​​the car. The gripper assembly 5 is used to organize the materials inside the car, ensuring their orderly stacking.

[0043] Because trucks are prone to colliding with the gripper assembly 5 when reversing into the workshop, a vertically arranged telescopic column 7 is installed at the lower end of the H-beam 11. The telescopic end of the telescopic column 7 is raised and lowered by an electric cylinder. The base of the robotic arm 6 is installed at the lower end of the telescopic column 7. The installation of the telescopic column 7 not only allows the gripper assembly 5 to be raised when the truck enters the workshop to avoid collision, but also makes the height of the gripper assembly 5 adjustable, thereby expanding the range of movement of the gripper assembly 5 and improving its flexibility.

[0044] The working principle of this embodiment is as follows:

[0045] 1. The screw drive device drives the first conveyor 2 to move to the right side, to the position where the bagged plastic granules are stacked;

[0046] 2. Place the bagged plastic granules at the right end of the first conveyor 2, and as the first conveyor 2 runs, the upper end of the first conveyor 2 will be filled with the bagged plastic granules.

[0047] 3. The screw drive device drives the first conveyor 2 to move to the left, so that the right end of the second conveyor 3 is directly above the front or rear end of the truck body;

[0048] 4. Adjust the height of the right end of the second conveyor 3 to meet the requirements for the height of lost packages;

[0049] 5. The first conveyor 2, the second conveyor 3, and the screw drive device are started, so that the bagged plastic granules are laid and piled up in the carriage from the first end to the last end or from the last end to the first end; at the same time, the lifting cylinder 41 moves up and down and back and forth, so that the bagged plastic granules fall after a brief stay on the DC platform.

[0050] Compared to existing technologies, the advantages of this embodiment are: 1. By fixing the linear conveyor device to the top of the workshop and coordinating the operation of the first and second conveyors 3, continuous automated conveying of plastic granules from the workshop to the truck bed is achieved. The introduction of the robotic arm 6 and the gripper assembly 5 replaces traditional manual stacking, completely eliminating the efficiency bottleneck of manual stacking, meeting the needs of large-scale, high-intensity transportation, and significantly improving the overall loading speed. 2. The linear conveyor device is fixedly installed on the top of the workshop, without occupying ground space, solving the problem of traditional ground-mounted mobile conveyors compressing the storage area of ​​plastic granules in the workshop, thereby indirectly increasing the workshop's storage capacity and further improving overall transportation efficiency. 3. By adjusting the height of the tail end of the second conveyor 3 through the rotating assembly 4, the height of the tail end of the second conveyor 3 from the drop surface is adjusted, so that when the bagged plastic granules fall, the bags will not break due to excessive impact.

[0051] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
