Description

Technical Field

[0001] This invention relates to the field of industrial white sugar conveying equipment, and more specifically to an industrial white sugar packaging and conveying system. Background Technology

[0002] The finished granulated sugar, produced during the sugar-making process in the factory, is packaged into bags using bagging equipment and then sealed. Since our factory uses 50kg large packaging bags, similar to fertilizer bags, these bags are quite heavy. After filling, the bags are sealed using a sealing machine; the bags are placed vertically during sealing to facilitate the process. After sealing, to facilitate subsequent gripping and stacking by industrial robots, the bags need to be laid flat before the robots can grasp them. However, due to changes in the bag's placement during transport, the material inside the bag shifts, resulting in uneven distribution and uneven weight distribution. This makes it easy for the bags to fall off when the industrial robot grasps them.

[0003] In addition to this issue, finished product packaging is transferred using lifting bags. Compared to pallets, lifting bags can hold stacked finished product packaging, and the lifting ropes along the outside of the finished product packaging can provide obstruction and restraint, making forklift transfer more stable. However, the lifting ropes on the lifting bags require manual operation by workers to pull up the ropes, wait for the forklift forks to move to the rope position, and then manually hook the ropes onto the forks before lifting and transferring the product. During this process, manual pulling of the ropes is inaccurate, requiring manual adjustment in coordination with the forklift each time. Furthermore, after workers have completed the forklift support of the lifting ropes, they also need to pre-arrange the lifting bags on one side of the conveyor track for the next lifting bag installation, but the transport track obstructs this, limiting the coordination between workers on both sides. Based on these circumstances, an industrial white sugar packaging conveyor system was designed to solve the aforementioned problems and improve transportation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an industrial white sugar packaging and conveying system. This system simultaneously inverts sealed packaging bags and redistributes unevenly distributed material within the bags, ensuring the bags are neatly arranged and easy for industrial robots to grasp. Finished packages are stacked above pre-positioned lifting bags, with the lifting ropes fixed in place, eliminating the need for manual handling while waiting for a forklift to lift. Furthermore, the bags are pre-arranged below the track; after the track is disengaged, workers on both sides can directly place the arranged bags onto the transport railcar to complete the installation, reducing worker steps and improving equipment operating efficiency.

Detailed Implementation like Figure 1-2 As shown, to achieve the above objectives, the present invention provides the following technical solution: an industrial white sugar packaging and conveying system. The main function of this system is to change the finished product packaging bag 12 from an upright state to a horizontal position, and to adjust the distribution of the material inside the packaging bag 12 in the horizontal state, ensuring that the industrial robot 3 can stably grip it. After the finished product packaging bags 12 are stacked, they are transferred to the forklift lifting position, where the lifting rope 9.1 can smoothly lift the packaging bags 12. The operator's work is limited to laying the bags 9 and suspending the lifting rope 9.1, reducing their workload.

[0026] like Figure 1 , 2As shown in Figures 7, 8, and 9, the starting position of the system is connected to the discharge end of the sealing machine. The sealed packaging bag 12 enters from the feeding end of the bag-inverting mechanism 1 in a vertical state; the packaging bag 12 moves out from the discharge end of the bag-inverting mechanism 1 and enters the leveling mechanism 2 in a horizontal state; an industrial robot 3 is installed at the discharge end of the leveling mechanism 2, and a fence is installed outside the working range of the industrial robot 3 for protection. Industrial robot 3 uses grippers 3.1 to repeatedly grip individual packaging bags 12 and stack them above hanging bags 9 on the surface of transport railcar 4; transport railcar 4 moves along the loading end of conveyor rail group 5 to the unloading end on the other side; transport railcar 4 is equipped with a platform 4.1; movable holes are provided on both sides of the surface of platform 4.1; support rods 6 are movably installed in the movable holes; support rods 6 on the same side of platform 4.1 are fixedly connected by connecting plates 8; lifting cylinder 7 is fixed above platform 4.1; the telescopic end of lifting cylinder 7 passes through platform 4.1 and is fixedly connected to connecting plate 8; the top of support rod 6 is equipped with two support heads 6.1; the top of support head 6.1 has a slot for placing lifting rope 9.1; the gap between the support heads 6.1 is used to open the lifting rings 9.2 of the lifting rope 9.1. The gap between the lifting rings 9.2 and the support heads 6.1 is the position for the forklift forks to insert. The bottom of the car body 4.1 of the transport railcar 4 is equipped with rail wheels 4.2. The rail wheels 4.2 move along the rail group after the fixed rail 5.1 and the moving rail 5.2 are connected. The rail wheels 4.2 are driven by the first motor 4.3.

[0027] Example 1: The conveyor rail assembly 5 includes a fixed rail 5.1, a moving rail 5.2, a movable base plate 5.3, a fixed plate 5.4, and a hydraulic cylinder 5.5. The loading end of the fixed rail 5.1 is mounted within the handling range of the gripper 3.1 of the industrial robot 3. The unloading end of the fixed rail 5.1 is mounted on the fixed plate 5.4. The movable base plate 5.3 is slidably mounted above the fixed plate 5.4. The moving rail 5.2 is fixed above the movable base plate 5.3. The hydraulic cylinder 5.5 is fixed below the fixed plate 5.4. The telescopic end of the hydraulic cylinder 5.5 is connected to one side of the movable base plate 5.3. Support legs 5.6 are fixed below the movable base plate 5.3, the fixed rail 5.1, and the fixed plate 5.4. The support legs 5.6 below the movable base plate 5.3 are located at the bottom of the end of the movable base plate 5.3. A traveling wheel 5.7 is fixed to the bottom of the support legs 5.6 below the movable base plate 5.3. Below the disconnection point between the moving rail 5.2 and the fixed rail 5.1, there is a bag-carrying conveyor rail 10 perpendicular to the moving rail. A pre-laying trolley 11 is mounted on the bag-carrying conveyor rail 10, with neatly arranged bags 9 stacked on its surface. The pre-laying trolley 11 moves on the same principle as the transport rail car 4, driven by a motor. The conveyor rail assembly 5 ensures the finished product packaging on the transport rail car 4. When the moving rail 5.2 is disconnected, operators can stand on either side of the moving rail 5.2 and pull on one side of the lifting rope 9.1 to lift the bags 9 below. After the moving rail 5.2 returns to its original position, the bags 9 are placed on the surface of the transport rail car 4. When the hydraulic cylinder 5.5 is in the retracted state, one end of the moving rail 5.2 aligns with the discharge end of the fixed rail 5.1; the transport rail car 4 moves along the aligned track. After the hydraulic cylinder 5.5 extends to its maximum stroke, the moving rail 5.2 disconnects from the fixed rail 5.1, allowing the bags 9 below to move upwards for easy removal by operators.

[0028] like Figure 3 , 4 As shown, the bag-pouring mechanism 1 is configured as follows: The bag-tipping mechanism 1 includes a first conveyor belt 1.11, a bag-blocking plate 1.12, a second conveyor belt 1.13, a support 1.14, a bag-pushing frame 1.16, a bag-pushing plate 1.17, a bag-pushing cylinder 1.18, a bag-tipping frame 1.19, a bag-tipping plate 1.20, a pressure roller 1.21, and an adjusting frame 1.22; guardrails to prevent the packaging bags from tipping over are fixed on both sides of the feeding end of the first conveyor belt 1.11; a second conveyor belt 1.13 is provided on one side of the conveying end of the first conveyor belt 1.11; The second conveyor belt 1.13 is perpendicular to the first conveyor belt 1.11; a bracket 1.14 is fixed on the other side of the conveying end of the first conveyor belt 1.11; a connector 1.24 is provided on the top of the bracket 1.14; the connector 1.24 is fixedly connected to the top of the bag-turning frame 1.19; a bag-turning plate 1.20 is fixed on the bag-turning frame 1.19; a pressure roller 1.21 is movably provided at the bottom of the bag-turning frame 1.19; the frame body of the bag-turning frame 1.19 is fixedly connected to the end of the adjusting frame 1.22. A bag-pushing cylinder 1.18 is provided inside the bracket 1.14; the end of the bag-pushing cylinder 1.18 is hinged to the crossbar 1.15 of the bracket 1.14; the telescopic end of the bag-pushing cylinder 1.18 is hinged to the back of the bag-pushing plate 1.17; the bag-pushing plate 1.17 is fixed to the bag-pushing frame 1.16; the top of the bag-pushing frame 1.16 has an L-shaped structure; the top end of the bag-pushing frame 1.16 is movably connected to the connector 1.24; a bag-stop plate 1.12 is provided at the conveying end of the first conveyor belt 1.11; a roller group 1.23 is inclined at the connection position of the first conveyor belt 1.11 and the second conveyor belt 1.13, and the roller group 1.23 is used to transition the bag-pouring position to avoid the height difference affecting the conveying of the packaging bag 12.

[0029] like Figure 5 , 6 As shown, the leveling mechanism 2 is configured as follows: The leveling mechanism 2 includes a conveying square roller 2.1, a flat conveyor belt 2.2, a feeding conveyor roller 2.3, a support frame 2.4, a chute 2.5, a slider 2.6, an adjusting screw 2.7, a crossbeam 2.8, a square roller pressure wheel 2.9, and a second motor 2.10. The conveying square roller 2.1, the flat conveyor belt 2.2, and the feeding conveyor roller 2.3 are connected in sequence. The discharge end of the bag-pouring mechanism 1 is connected to one end of the conveying square roller 2.1. The support frame 2.4 is horizontally mounted on the frame of the flat conveyor belt 2.2. A chute 2.5 is vertically fixed on one side of the support frame 2.4. A slider 2.6 is slidably mounted in the chute 2.5. An adjusting screw 2.7 passes through the middle of the slider 2.6, and the slider 2.6 is fixedly connected to the back of the crossbeam 2.8. A square roller pressure wheel 2.9 is rotatably mounted on the inner side of the crossbeam 2.8, and the square roller pressure wheel 2.9 is driven by the second motor 2.10. Adjusting screw 2.7 controls the raising and lowering of square roller pressure roller 2.9, allowing adjustment of its height as needed. The leveling mechanism 2 uses conveying square roller 2.1 to level the bottom of the packaging bag 12 and square roller pressure roller 2.9 and pressure roller 1.21 to level the surface of the packaging bag 12. The conveying square roller 2.1 and the flat conveyor belt 2.2 are also driven by motors, simultaneously performing the leveling operation on the packaging bag 12. Unless otherwise described, all fixing methods described above utilize welding or threaded fastening techniques commonly used by industry professionals.

[0030] The system workflow is as follows: The packaging bag 12, emerging from the sealing machine conveyor line, is in an upright position. It enters the first conveyor belt 1.11 and stops at the end of the first conveyor belt 1.11. When the bag-inverting mechanism 1 pushes the packaging bag 12, the packaging bag 12 is acted upon by the bag-stopping plate 1.12, changing the packaging bag 12 from an upright position to a horizontal position. During the state change, the position of the material inside the bag changes accordingly. After the packaging bag 12 moves from the bag-inverting mechanism 1 to the leveling mechanism 2, the conveying square roller 2.1 can change the position of the material inside the packaging bag 12 during the conveying process, making it level. When it passes through the square roller pressure roller 2.9, the square roller pressure roller 2.9 has its height adjusted in advance according to the packaging specifications. This allows the pressure roller 1.21 of the square roller pressure roller 2.9 to contact the surface of the packaging bag 12, thus leveling the material inside the packaging bag 12. After being flattened and packaged, the bags reach the feeding conveyor roller 2.3. The transport railcar 4 needs to move to the outside of the fence first. The operators lay the hanging bags 9 outside the fence. When the hanging bags 9 are taken away, the moving rail 5.2 needs to be disconnected from the fixed rail 5.1. After disconnection, the hanging bags 9 below are lifted out by the operators on both sides. After the hanging bags 9 are taken out, the moving rail 5.2 is reset and reconnected, and the hanging bags 9 are laid on the transport railcar 4. The transport railcar 4 carries the laid hanging bags 9 into the fence and reaches the feeding end of the fixed rail 5.1. The industrial robot 3 picks up the packaging bag 12 and places it on the surface of the hanging bag 9. The operation is repeated until the required quantity is reached. Then, the transport railcar 4 moves to the forklift feeding end. The forklift's forks are inserted into the lifting ring 9.2, and after lifting, the hanging bags 9 are transferred into the warehouse.
