Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and in particular to a bagged cement batching system. Background Technology

[0002] Because of its greater flexibility, bagged cement is one of the main sales channels for cement plants. Currently, the production of bagged cement is mainly based on customer orders. Goods are prepared in advance, temporarily bagged and sealed, and then stacked by robotic arms. When loading, the robotic arms deliver the cement to the conveyor belt for loading, in order to increase the factory's inventory and loading efficiency, especially to alleviate the bagging pressure during peak loading periods.

[0003] Palletizing consists of two forms. One is to divide palletizing areas on both sides of the conveyor belt, where robotic arms stack cement directly on the ground. This method requires raising the pallet height to accommodate the robotic arm's operating height, but this method affects subsequent changes to the factory area. Therefore, the only solution is to use supports to increase the height for easy dismantling. However, this process results in relatively high pallets, posing a certain degree of danger. Furthermore, due to the limited operating height of the robotic arm, the sides of the conveyor belt cannot store a large amount of cement (generally, three to four layers are sufficient for the robotic arm's vertical stacking height, requiring larger robotic arms and increasing costs). Therefore, the solution is to add tracks to the bottom of the robotic arm to extend the palletizing area. However, this method still does not meet the storage requirements, and the large amount of cement piled on the conveyor belt poses a certain degree of danger. The second method uses stackable racks for palletizing, and then forklifts transport the cement to designated areas. This process allows for on-demand palletizing, but it requires forklift drivers to be stationed at fixed points, failing to achieve unattended operation. To address these issues, we propose a bagged cement batching system. Utility Model Content

[0004] This application provides a bagged cement batching system that solves the problems of low storage efficiency and complex transportation process of bagged cement.

[0005] This application provides a bagged cement batching system, including a conveyor belt, on which a robotic arm for handling cement is installed. A rotating frame is provided on the side of the conveyor belt, and multiple placement frames are provided around the circumference of the rotating frame. Placement plates are placed inside the placement frames. A positioning mechanism is provided on the side of the rotating frame, and a lifting structure is also provided on the corresponding side of the conveyor belt. The lifting structure corresponds to the placement frames.

[0006] Preferably, the rotating frame comprises multiple frames respectively disposed on both sides of the conveyor belt.

[0007] Preferably, the rotating frame is driven by a motor, and a support roller is installed at the bottom of the rotating frame.

[0008] Preferably, the positioning mechanism includes a positioning sensor installed on the ground, and a sensing structure is provided at the bottom of the rotating frame and at the corresponding position of the placement frame.

[0009] Preferably, the lifting structure includes a lifting cylinder installed at the lower part of the rotating frame, and a top plate is installed on the top of the lifting cylinder, the top plate corresponding to the placement frame.

[0010] Preferably, positioning plates are provided on both sides of the bottom of the placement frame in the direction of movement.

[0011] Preferably, the placement frame is provided with a placement groove, and the top plate is located in the placement groove.

[0012] Preferably, a limiting groove is provided on the ground, and the support roller is located in the limiting groove.

[0013] As can be seen from the above technical solution, this application provides a bagged cement batching system. During operation, the rotating frame rotates to control the placement frame to the designated position, and the lifting structure lifts the placement plate to the designated height. The bagged cement production line starts working. The bagged cement is sent to the gripping position of the robot arm by the conveyor belt. The robot arm stacks the cement on the placement plate. When the specified number of stacks is reached, the lifting structure resets and places the placement plate in the placement frame. The rotating frame rotates again to one station to perform the stacking work of the next placement frame. When the placement plate requires a higher stacking height, the lifting structure can lower the placement plate when the robot arm reaches the maximum stacking height, so that the robot arm can continue stacking. The design height of the rotating frame is close to the ground.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up rotating frames and placement frames, multiple placement areas can be set on both sides of the conveyor belt, and the placement areas can be transformed according to needs, so as to configure different numbers of placement frames according to orders, realize order requirements for palletizing, and greatly improve the placement capacity on both sides of the conveyor belt.

[0016] 2. By setting up the lifting structure, the height of the placement plate can be changed, allowing the robot arm to stack at a suitable height, further increasing the stacking height of the placement plate. At the same time, it also further reduces the height of the rotating frame, so that the stacked cement is as low as possible and close to the ground, making it easier for staff to inspect.

[0017] 3. By setting up a positioning mechanism, the positioning accuracy of the rotating frame during rotation is improved, which further improves the accuracy of the robot when stacking, so that the robot can stack according to the programmed height without the need for additional positioning.

[0018] In summary, this application enables large-scale palletizing and transportation on both sides of the conveyor belt, realizes the pre-packaging of large-volume orders, and can meet the palletizing requirements of multiple orders, improving the loading efficiency of large-volume orders. At the same time, the center of gravity of this application after loading is low, the safety is high, and it is easy to inspect and clear through cameras, thus preparing for further improvement of automation.

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] See Figure 1-3A bagged cement batching system is disclosed in this application. This system is used to improve the cement storage and transportation capacity of a bagged cement production line. The system includes a conveyor belt 5, on which a robotic arm 4 for handling cement is installed. The robotic arm 4 can be installed in two ways: a first is a fixed installation, and the second is a mobile installation, that is, it is installed on the conveyor belt 5 via a track and can be moved according to instructions. The robotic arm 4 is equipped with a sensing and positioning device for sensing bagged cement, enabling it to accurately grasp cement. See existing robotic arm palletizing technology for details. A rotating frame 1 is installed on the side of the conveyor belt 5. In this application, multiple rotating frames 1 are respectively arranged on both sides of the conveyor belt 5. One robotic arm 4 can feed material to the rotating frames 1 on both sides, further increasing the storage capacity of bagged cement. When there are four rotating frames 1, they can be respectively arranged on both sides of the conveyor belt 5, with two robotic arms 4 installed to complete the grasping and transfer work, further increasing storage capacity and conveying efficiency. Multiple placement frames 2 are arranged around the circumference of the rotating frame 1. In this application, cement is placed using multiple placement frames 2. Specifically, a placement plate 11 is set inside the placement frame 2. Bagged cement is placed on the placement plate 11 for palletizing. During palletizing, each placement plate 11 can be set to stack multiple layers, with five bags per layer, or multiples of five bags, to improve palletizing stability. When the material on a placement plate 11 is in place, the rotating frame 1 is controlled to complete the palletizing process. The rotating frame 1 rotates to another placement box 2 for stacking. The side of the rotating frame 1 is equipped with a positioning mechanism to position the placement box 2. Whenever the placement box 2 is rotated and changed, it is positioned by the positioning mechanism. The side of the corresponding conveyor belt 5 is also equipped with a lifting structure. In this application, since the design height of the rotating frame 1 is close to the ground, the placement plate 11 is lower than the lowest position of the robot arm 4. Therefore, the height of the placement plate 11 is adjusted by the lifting structure. Thus, the lifting structure corresponds to the placement box 2. That is, the placement box 2 after each adjustment needs to correspond with the robot arm 4 and the lifting structure. This application is used in conjunction with a bagged cement filling system. It can fill, transport, and store in advance according to the order requirements. The entire system shares a single conveyor belt 5 and robot arm 4. After filling, the material is moved to the robot arm 4 via the conveyor belt 5 and then transferred to the placement box 2 by the robot arm 4. When discharging, the robot arm transfers the material on the placement box 2 to the conveyor belt 5 via the robot arm 4 to complete the material transfer.

[0026] In this application, in order to further improve the stability of the rotating frame 1, the rotating frame 1 is driven by a motor. It should be understood that the rotating frame 1 is driven by the main shaft of the gearbox, and the motor drives the gearbox. The bottom of the rotating frame 1 is equipped with a support roller 7 to support the rotating frame 1, so that cement can be transferred on either side. Furthermore, a limit groove 12 is provided on the ground, and the support roller 7 is located in the limit groove 12. The support roller 7 can only move along the limit groove 12, thereby improving the stability of the rotating frame 1 and its resistance to deformation.

[0027] In this application, the positioning mechanism includes a positioning sensor 10 installed on the ground. The positioning sensor 10 performs positioning through a corresponding sensing module. Therefore, a sensing structure is provided at the bottom of the rotating frame 1 and the corresponding position of the placement frame 2. When the rotating frame 1 rotates, the sensing structure contacts the positioning sensor 10, triggering the positioning sensor 10 to realize the positioning function when the rotating frame 1 rotates.

[0028] In this application, the lifting structure includes a lifting cylinder 9 installed at the lower part of the rotating frame 1. Since the rotating frame 1 is close to the ground, a groove can be set on the ground to install the lifting cylinder 9 into the groove. A top plate 3 is installed on the top of the lifting cylinder 9. The top plate 3 corresponds to the placement frame 2. When the placement frame 2 moves to the corresponding position, the lifting cylinder 9 lifts the placement plate 11 to the height of the robot arm 4 for loading. The lifting cylinder 9 can be adjusted according to the set height to meet the palletizing requirements of different heights.

[0029] In this application, in order to further improve the positional accuracy of the placement frame 2, positioning plates 8 are provided on both sides of the bottom moving direction of the placement frame 2. The two positioning plates 8 are arranged in a V-shape. After the positioning mechanism completes the approximate positioning, when the lifting cylinder 9 controls the top plate 3 to move upward, if the positioning mechanism deviates, the top plate 3 will hit the positioning plate 8, moving the placement frame 2 to one side, so that the top plate 3 can pass through the placement frame 2, thereby lifting the placement plate 11 and completing the secondary positioning of the placement frame 2.

[0030] As can be seen from the above technical solution, during operation, the rotating frame 1 rotates to control the placement frame 2 to the designated position, and the lifting structure lifts the placement plate 11 to the designated height, and the bagged cement production line starts working. The bagged cement is sent to the gripping position of the robot arm 4 by the conveyor belt 5, and the robot arm 14 stacks the cement on the placement plate 11. When the stacking reaches the specified quantity, the lifting structure resets and places the placement plate 11 in the placement frame 2. The rotating frame 1 rotates again to one station to carry out the stacking work of the next placement frame 2. When the placement plate 11 needs a higher stacking height, the lifting structure can lower the placement plate 11 when the robot arm 4 reaches the maximum stacking height, so that the robot arm 4 can continue to stack. The design height of the rotating frame 1 is close to the ground, which lowers the center of gravity.
