Description

Technical Field

[0001] This utility model relates to a bagged material palletizing device, and more particularly to a bagged material palletizing device. Background Technology

[0002] In the palletizing process of fertilizer production, the forklifting and flattening of bagged fertilizer is a crucial step in ensuring palletizing quality and efficiency. Existing palletizing equipment suffers from two major shortcomings: Firstly, the moving mechanism for picking up fertilizer is driven by a servo motor, which has a complex structure and high integration, resulting in high maintenance difficulty and cost, making it difficult to meet the rapid maintenance needs in mass production. Secondly, the fertilizer bag flattening mechanism uses a combination structure of "single cylinder + plate," resulting in concentrated but unevenly distributed flattening force. This easily leads to flatness issues, where the fertilizer bags are "lower in the middle and higher on both sides," affecting the regularity of subsequent stacking. Furthermore, traditional flattening mechanisms cannot flexibly adjust the flattening range according to different fertilizer bag sizes, exhibiting poor adaptability and limiting the equipment's applicable scenarios. These problems not only reduce stacking efficiency but may also cause insufficient stacking stability due to irregular placement of fertilizer bags, inconveniencing the production process. Summary of the Invention

[0003] To address the problems of existing technologies, this utility model provides a bagged material palletizing device, which not only improves equipment uptime but also ensures that the bagged materials remain flat after stacking, thus enhancing the stability of the stacking.

[0004] The technical solution adopted in this utility model is as follows: A bagged material palletizing device includes a palletizing mechanism installed on one side of a conveyor line, and a palletizing tray disposed on the other side of the palletizing mechanism. The palletizing mechanism includes a robot base, on which a palletizing robot is disposed. The end of the robotic arm of the palletizing robot is connected to a fork-and-flattening mechanism, which is used to fork up the bagged material on the conveyor line and transfer it to the palletizing tray, and flatten it during the transfer process.

[0005] Preferably, the fork-lifting and flattening mechanism includes a fixed plate connected to the robotic arm. A sliding bushing is provided at the bottom of the fixed plate, and a sliding shaft is inserted inside the sliding bushing. One end of the sliding shaft is connected to a fork bracket, and a fork is connected below the fork bracket. A double-fork-lifting cylinder structure is provided between the fork bracket and the fixed plate. The extension and retraction of the piston rod of the double-fork-lifting cylinder structure enables the fork bracket to move horizontally relative to the fixed plate, thereby driving the fork to move horizontally and realizing the fork-lifting action of bagged material. At least three sets of flattening components are provided on the front and rear sides of the fixed plate. Each set of flattening components includes a flattening cylinder fixed to the side of the fixed plate and a flattening tube connected to the piston rod end of the flattening cylinder. Each set of flattening cylinders is individually controlled by a PLC controller to realize the partial or overall flattening of bagged material during the transfer process.

[0006] Preferably, a baffle is connected to the side of the fixing plate via a baffle bracket.

[0007] Preferably, the flattening components are in three sets.

[0008] Preferably, the fixing plate is connected to the end of the palletizing robot's robotic arm via a rotating column, and the rotating column is linked to a rotary motor on one side of the end of the robotic arm.

[0009] Preferably, the dual-fork air intake structure includes a first cylinder fixed to the fixed plate by a first bracket and a second cylinder fixed to the fork bracket by a second bracket, wherein the first piston rod of the first cylinder is connected to the second piston rod of the second cylinder.

[0010] The beneficial effects of the technical solution provided by this utility model are: 1. Simplified structure and convenient maintenance: The dual-cylinder drive replaces the servo motor, which greatly simplifies the mechanical structure of the forklift mechanism, reduces the difficulty of maintenance and maintenance costs, and improves the equipment's uptime. 2. Significantly improved flattening effect: At least six sets of flattening cylinders are distributed on both sides to work with square tubes to flatten the fertilizer bags, so that the force is evenly covered in the middle and both sides of the fertilizer bags, completely solving the flatness problem of "low in the middle and high on both sides" and ensuring the neatness of stacking. 3. Enhanced adaptability: Supports personalized flattening control for fertilizer bags of different sizes, meeting the production needs of multiple specifications without changing tooling, thus expanding the equipment's applicability. 4. Economical and practical: Compared with servo motors, cylinder-driven solutions are less expensive and more energy-efficient, improving performance while reducing equipment procurement and operating costs, resulting in higher cost-effectiveness.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0014] As attached Figure 1 As shown, a bagged material palletizing device of this embodiment includes a palletizing mechanism installed on one side of a conveyor line 1, and a palletizing tray 2 provided on the other side of the palletizing mechanism. The palletizing mechanism includes a robot base 3, and a palletizing robot 4 is provided on the robot base 3. The end of the robotic arm of the palletizing robot 4 is connected to a fork-lifting and flattening mechanism 5. The fork-lifting and flattening mechanism 5 is used to lift the bagged material 6 on the conveyor line 1 and transfer it to the palletizing tray 2 and place it down, and flatten it during the transfer process.

[0015] As attached Figure 2-6As shown, the fork-lifting and flattening mechanism 5 of this embodiment includes a fixed plate 51 connected to the robotic arm. A sliding bushing 52 is provided at the bottom of the fixed plate 51, and a sliding shaft 53 is inserted inside the sliding bushing 52. One end of the sliding shaft 53 is connected to a fork bracket 54, and a fork 55 is connected below the fork bracket 54. A double-fork lifting cylinder structure 56 is provided between the fork bracket 54 and the fixed plate 51. The extension and retraction of the piston rod of the double-fork lifting cylinder structure 56 realizes the horizontal movement of the fork bracket 54 relative to the fixed plate 51, thereby driving the fork 55 to move horizontally and realize the fork-lifting action of the bagged material 6. Three sets of flattening components 57 are respectively provided on the front and rear sides of the fixed plate 51. Each set of flattening components 57 includes a flattening cylinder 571 fixed on the side of the fixed plate 51 and a flattening tube 572 connected to the piston rod end of the flattening cylinder 571. Each set of flattening cylinders 571 is individually controlled by a PLC controller to realize the partial or overall flattening of the bagged material during the transfer process.

[0016] In this embodiment, a baffle 512 is connected to the side of the fixing plate 51 via a baffle bracket 511.

[0017] In this embodiment, the fixed plate 51 is connected to the end of the palletizing robot 4 via a rotating column 7. The rotating column 7 is linked to a rotary motor 8 located on one side of the end of the robotic arm. The rotary motor 8 controls the rotating column 7 to drive the fork-lifting and flattening mechanism 5 below to achieve overall rotation.

[0018] The double-fork air intake structure 56 in this embodiment includes a first cylinder 562 fixed to the fixed plate 51 by a first bracket 561 and a second cylinder 564 fixed to the fork bracket 54 by a second bracket 563. The first piston rod 565 of the first cylinder 562 is connected to the second piston rod 566 of the second cylinder 563.

[0019] The workflow of a bagged material palletizing device according to this embodiment is as follows: 1. Workstation standby and material inspection The equipment is in the initial standby state: the palletizing robot arm returns to the position above the forklift station, the double forklift cylinder structure is in the retracted state, and the pressure tube is in the raised position; after the conveyor line transports the fertilizer bags (of different sizes) to be palletized to the forklift station, the photoelectric sensor at the station detects the material and sends a "material in place" signal to the PLC controller.

[0020] 2. Action of picking up fertilizer bags with a fork After receiving the signal, the PLC controls the two cylinders of the fork-picking mechanism to extend synchronously, driving the forks to insert into the bottom of the fertilizer bag until they are blocked by the baffle. After the forks are fully inserted into the support position under the bag, the two cylinders remain in the retracted state. At the same time, the lifting joint of the robotic arm is activated, driving the fork-picking assembly (and fertilizer bag) to be lifted upward by 5-10cm, completing the picking up and unloading of the material from the conveyor line.

[0021] 3. Size identification and flattening preparation As the fork lifts, fertilizer bags of different widths arrive at the workstation in sequence. The PLC controller can determine the number of cylinders required to flatten the bags according to the preset cylinder-to-size logic (e.g., 2 sets of cylinders are activated for small bags, and 3 sets are activated for large bags).

[0022] 4. Precise flattening at the flattening station During the process of the robotic arm driving the forklift assembly (including fertilizer bags) to the palletizing tray, the PLC controls the corresponding number of flattening cylinders to extend synchronously, pushing the flattening tube downward to fit against the surface of the fertilizer bag. Since the cylinders are distributed in three parts, the flattening tube can apply uniform downward pressure to the middle and side areas of the fertilizer bag at the same time, avoiding the problem of "low in the middle and high on the sides". After the flattening action lasts for 2-3 seconds, the flattening cylinder retracts and the flattening tube returns to its original position and lifts up.

[0023] 5. Material delivery at the palletizing station After flattening, the robotic arm moves the entire fork to above the palletizing tray and adjusts it to the target placement position according to the preset number of palletizing layers and arrangement. Then, the double-fork cylinder structure retracts synchronously, the fork retracts, and the fertilizer bag is blocked by the baffle and placed stably in the corresponding position on the pallet. The robotic arm returns to the fork-picking station and waits for the next fertilizer bag to arrive before starting the next work cycle. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
