Description

Technical Field

[0001] This utility model belongs to the field of bagged goods transportation technology, and relates to a transportation line. Background Technology

[0002] Bagged goods are usually cement bags, etc. To ensure efficient transportation and stacking on freight trucks, a transport route is usually set up. The bagged goods are first stacked, then grabbed by a robotic arm, and then slid along the mechanical gantry and placed on the freight truck.

[0003] Because there are multiple stacked bags of goods, they are prone to slipping when the robotic arm grabs them. Therefore, the current practice is to place packing cloth on the stacking trolley, stack the bags of goods on the packing cloth, and then tie the two ends of the packing cloth together. The two ends of the packing cloth are also equipped with lifting rings, which are hung on the robotic arm or the hoist of the mechanical gantry. The robotic arm or hoist is then moved to move the packing cloth onto the freight vehicle.

[0004] However, the above method uses manual packaging, and since the bagged goods are not stably secured inside, there is a risk of slipping during transportation, which reduces the packaging efficiency and effectiveness of the bagged goods. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a transportation line. The technical problem this utility model aims to solve is: how to address the low packing efficiency of existing bagged goods transportation routes.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A transport line includes a waste weighing and detection device, a stacking device, and a strapping device arranged sequentially along the transport direction of bagged goods packages. The line is characterized by a feeding conveyor roller between the waste weighing and detection device and the stacking device. The stacking device includes a transport trolley, and the feeding conveyor roller is capable of transporting qualified bagged goods packages from the waste weighing and detection device to the transport trolley. The transport trolley includes a stacking conveyor belt for stacking bagged goods packages. The strapping device includes at least one strapping conveyor belt, which transports the stacked bagged goods packages onto the strapping conveyor belt. Each strapping conveyor belt is equipped with two spaced-apart strapping machines capable of strapping the same stack of bagged goods packages.

[0008] The bagged goods are placed on a waste weighing and detection device for weighing. After passing the test, the bagged goods are conveyed via a feeding conveyor roller to a transport trolley in the stacking device. The bagged goods are then stacked on the stacking conveyor belt of the transport trolley and directly transported to a strapping conveyor belt. The strapping conveyor belt is equipped with two spaced-apart strapping machines. The two strapping machines on the same strapping conveyor belt simultaneously strap the same stacked bagged goods, so that the stacked bagged goods only need to stop once during strapping. This structure, which first weighs and detects the bagged goods, then stacks them, and finally straps them, achieves the packaging of stacked bagged goods and enables rapid transport of the bagged goods. The fully automated structure eliminates the need for manual operation, improving the efficiency of bagged goods packaging and transportation.

[0009] In the aforementioned transport line, the waste weighing and detection device includes a weighing platform and a waste removal platform arranged sequentially along the transport direction of the bagged goods. The weighing platform is equipped with a weighing conveyor belt, and the waste removal platform is equipped with a waste conveyor belt and a drive cylinder. The conveying shaft of the waste conveyor belt near the weighing conveyor belt is fixedly connected to the piston rod of the drive cylinder, and the drive cylinder can push one end of the waste conveyor belt to move upward. The feeding conveyor roller is located at the other end of the waste conveyor belt.

[0010] The bagged goods are placed on a weighing conveyor belt for weighing. After weighing, they are transferred to a waste conveyor belt. If the weighing is qualified, the drive cylinder does not start, but the goods are directly transported to the feed conveyor roller via the waste conveyor belt. If the weighing is unqualified, the drive pneumatic system starts, which moves one end of the waste conveyor belt upward, causing the bagged goods on the waste conveyor belt to fall off from the other end. This achieves the purpose of waste rejection, while qualified bagged goods can be continuously transported, thus ensuring the packaging stability of intact bagged goods.

[0011] In the aforementioned transport line, the drive cylinder is located at one end of the waste removal platform, and the waste removal platform is provided with a waste removal plate that is inclined downward from one end near the drive cylinder to the other end, and the waste removal plate is located below the waste conveyor belt.

[0012] The waste removal plate is designed to ensure that bagged goods removed from the waste conveyor belt can fall steadily through the guide plate, preventing the contents of the bagged goods from spilling out when falling directly, thus improving the stability of waste removal.

[0013] In the above-mentioned transport line, a discharge platform is provided between the feeding conveyor roller and the stacking device. The discharge platform is provided with a discharge conveyor belt connected to the feeding conveyor roller. The discharge platform is provided with a double door panel. The transport trolley can be located below the double door panel. The bagged goods package on the discharge conveyor belt is transported to the double door panel and falls onto the corresponding transport trolley.

[0014] The bagged goods packages on the feeding conveyor rollers are transferred to the unloading conveyor belt on the unloading platform. The bagged goods packages are then transferred to the double-door panel via the unloading conveyor belt. Opening the double-door panel allows the bagged goods packages to fall onto the corresponding transport trolleys, enabling the bagged goods packages to be stacked on the transport trolleys and improving the speed of stacking.

[0015] In the aforementioned transport line, the stacking device further includes two stacking slide rails arranged perpendicular to the transport direction. Multiple transport trolleys are mounted on the stacking slide rails, and each transport trolley is equipped with a transport cylinder that drives the stacking conveyor belt to move vertically.

[0016] Multiple transport trolleys can be installed on the stacking slide rails according to specific needs, which facilitates the use of multiple strapping conveyor belts and greatly improves the conveying efficiency. The setting of transport cylinders allows the stacking conveyor belts of the transport trolleys to be lifted by the transport cylinders after stacking, so that the stacking conveyor belts are aligned with the strapping conveyor belts, and the stacked bagged goods are transported to the strapping conveyor belts, which improves the stacking effect of the stacking trolleys and also avoids the need for the double-door panels to be set higher, thus improving the rational use of space.

[0017] In the aforementioned transport line, there are two transport trolleys and two strapping conveyor belts, and the strapping conveyor belts and transport trolleys are arranged in a one-to-one correspondence along the transport direction.

[0018] Since the stacking time is limited, the dual-line conveyor can achieve the highest efficiency. Therefore, the combination of two transport trolleys and two strapping conveyor belts further ensures the efficiency of the transport while also allowing for a more reasonable arrangement of the transported workpieces on the transport route.

[0019] In the aforementioned transport line, two strapping machines are arranged sequentially along the transport direction of the strapping conveyor belt.

[0020] This structure allows the bagged goods to be bundled only once, and after bundling, the bundled bags can be quickly transported along the conveying direction, improving conveying efficiency.

[0021] In the aforementioned transport line, mechanical trusses are provided on both sides of the strapping conveyor belt. Mechanical arms that can retract vertically are connected to the mechanical trusses. A side plate that is vertically arranged is connected to the lower end of the mechanical arm. An insert plate is connected to the side plate. The insert plate has a plate-shaped insert rod that is arranged horizontally. The insert rod is located on one side of the bottom end of the side plate. A connecting rod one and a drive cylinder are hinged to the side plate. A connecting rod two is hinged to the upper end of the connecting rod one. A push plate that is vertically arranged is hinged to the lower end of the connecting rod two. The piston rod of the drive cylinder is hinged to the connecting rod two and pushes the connecting rod two to move the push plate along the length direction of the insert rod.

[0022] The robotic arm extends downwards and moves to insert the insert rod of the insertion plate between the bagged goods and the existing conveyor structure, ensuring the entire bagged goods are positioned on the insert rod. The robotic arm then retracts upwards and moves to the corresponding unloading position, pushing the push plate. The push plate is connected to the side plate via connecting rod one and connecting rod two. The drive cylinder is hinged to the side plate, while the piston rod is hinged to connecting rod two. This design increases the push plate's stroke when the drive cylinder's stroke is insufficient, allowing the side plate and insertion plate to remain stationary. Only the drive cylinder pushes connecting rod two, which in turn moves the push plate to push the bagged goods outwards, thus achieving the desired unloading of the bagged goods. For unloading the bags, this structure uses a combination of an insert rod, a push plate, and a drive cylinder. When moving the bagged goods, the insert rod directly lifts the bagged goods; the robotic arm does not apply gripping force to the bagged goods. Instead, it lifts the bagged goods to the desired position, and then the drive cylinder pushes connecting rod one and connecting rod two, which in turn push the push plate to one side of the bagged goods, pushing it out. Because the push plate has a long stroke, it needs to push the entire bundled bagged goods out of the insert rod. Therefore, the combination of connecting rod one, connecting rod two, and the drive cylinder extends the movement stroke of the push plate, making it less likely to damage the bagged goods when the robotic arm moves them, thus improving stability.

[0023] Furthermore, to facilitate reset, a reset spring can be added between connecting rod one and connecting rod two. When no force is applied to the push plate, the return force of the reset spring will drive the push plate to reset quickly, thus improving the material feeding efficiency for multiple feeding operations.

[0024] In the aforementioned transport line, the mechanical truss has multiple vertically arranged support rods and a sliding longitudinal rod connected to the upper ends of all the support rods. Sliding frames are slidably connected to the two sliding longitudinal rods, and mechanical arms are connected to the sliding frames.

[0025] The mechanical truss uses multiple support rods and sliding longitudinal bars to ensure its structural strength and improve the stability of the sliding robotic arm on the sliding frame.

[0026] In the aforementioned transport line, the mechanical truss includes a frame, a sliding frame connected to the top of the frame, a mechanical arm connected to the sliding frame, and a longitudinal slide rail located on one side of the strapping conveyor belt and close to the bottom of the strapping conveyor belt. The bottom of the mechanical truss is slidably connected to the corresponding longitudinal slide rail and can slide along the longitudinal slide rail.

[0027] By placing the longitudinal slide rails on both sides of the conveyor belt, and setting them close to the bottom of the conveyor belt, installation only requires laying the longitudinal slide rails at the bottom of the frame. When adding a new production line, the laying and installation of the longitudinal slide rails can be achieved quickly, which is convenient for the staff. Since the longitudinal slide rails are laid close to the bottom of the conveyor belt, they do not affect the conveying of other parts in the factory. Furthermore, when there is a fault between the longitudinal slide rails and the frame, it can be quickly repaired and replaced, improving the convenience of mechanical truss installation and maintenance.

[0028] Compared with the prior art, the advantages of this utility model are as follows: the bagged goods are weighed and tested first, then the bagged goods are stacked, and then tied by a strapping machine, which realizes the packaging of the stacked bagged goods and the rapid transportation of the bagged goods. The fully automatic structure eliminates the need for staff to operate it, thus improving the packaging and transportation efficiency of bagged goods. Attached Figure Description

The feeding conveyor roller 11 can transport the qualified bagged goods packages in the waste weighing and detection device 1 to the transport trolley 21. The transport trolley 21 includes a stacking conveyor belt 22 for stacking bagged goods packages. The strapping device 3 includes at least one strapping conveyor belt 31. The stacking conveyor belt 22 can transport the stacked bagged goods packages to the strapping conveyor belt 31. Each strapping conveyor belt 31 is provided with two strapping machines 32 that are spaced apart and can strap the same stacked bagged goods packages.

[0044] The bagged goods are placed on the waste weighing and detection device 1 for weighing and detection. After passing the detection, the bagged goods are transported to the transport trolley 21 of the stacking device 2 via the feeding conveyor roller 11. After being stacked on the stacking conveyor belt 22 of the transport trolley 21, the bagged goods are directly transported to the strapping conveyor belt 31 via the stacking conveyor belt 22. The strapping conveyor belt 31 is equipped with two strapping machines 32 spaced apart. The two strapping machines 32 on the same strapping conveyor belt 31 simultaneously strap the same stacked bagged goods, so that the stacked bagged goods only need to stop once during strapping. Through the above structure, the bagged goods are weighed and detected first, then stacked, and then strapped by the strapping machine 32. This realizes the packaging of stacked bagged goods and the rapid transportation of bagged goods. The fully automatic structure eliminates the need for manual operation and improves the packaging and transportation efficiency of bagged goods.

[0045] like Figure 1 and Figure 2 As shown, the waste weighing and detection device 1 includes a weighing platform 12 and a waste removal platform 13 arranged sequentially along the conveying direction of bagged goods. The weighing platform 12 is equipped with a weighing conveyor belt 12a. The waste removal platform 13 is equipped with a waste conveyor belt 13a and a drive cylinder 13b. The conveying shaft 13c of the waste conveyor belt 13a near the weighing conveyor belt 12a is fixedly connected to the piston rod of the drive cylinder 13b. The drive cylinder 13b can push one end of the waste conveyor belt 13a to move upward. The feeding conveyor roller 11 is arranged at the other end of the waste conveyor belt 13a. The drive cylinder 13b is arranged at one end of the waste removal platform 13. The waste removal platform 13 is equipped with a waste removal plate 14 that is inclined downward from one end near the drive cylinder 13b to the other end. The waste removal plate 14 is located below the waste conveyor belt 13a.

[0046] like Figure 3-5 As shown, a feeding platform 4 is provided between the feeding conveyor roller 11 and the stacking device 2. The feeding platform 4 is provided with a feeding conveyor belt 41 connected to the feeding conveyor roller 11. The feeding platform 4 is provided with a double-door panel 42. The transport trolley 21 can be located below the double-door panel 42. The bagged goods package on the feeding conveyor belt 41 is transported to the double-door panel 42 and falls onto the corresponding transport trolley 21. The stacking device 2 also includes two stacking slide rails 23 arranged vertically in the conveying direction. Multiple transport trolleys 21 are provided on the stacking slide rails 23. The transport trolley 21 is provided with a transport cylinder 21a that drives the stacking conveyor belt 22 to move vertically. There are two transport trolleys 21 and two strapping conveyor belts 31. The strapping conveyor belts 31 and the transport trolleys 21 are arranged one-to-one in the conveying direction.

[0047] like Figure 6-9As shown, two strapping machines 32 are arranged sequentially along the conveying direction of the strapping conveyor belt 31. Mechanical trusses 5 are arranged on both sides of the strapping conveyor belt 31. Mechanical arms 51 that can retract vertically are connected to the mechanical trusses 5. The lower end of the mechanical arm 51 is connected to a side plate 52 arranged vertically. An insert plate 53 is connected to the side plate 52. The insert plate 53 has a plate-shaped insert rod portion 53a arranged horizontally. The insert rod portion 53a is located on one side of the bottom end of the side plate 52. The side plate 52 is hinged to a connecting rod 1 54a and a drive cylinder 7. The upper end of the connecting rod 1 54a is hinged to a connecting rod 2 54b. The lower end of the connecting rod 2 54b is hinged to a push plate 55 arranged vertically. The piston rod 71 of the drive cylinder 7 is hinged to the connecting rod 2 54b and pushes the connecting rod 2 54b to drive the push plate 55 to move along the length direction of the insert rod portion 53a.

[0048] By setting connecting rod 54a and connecting rod 54b, the side plate 52 and the push plate 55 are hinged, which increases the travel of the push plate 55 without affecting its pushing action. This facilitates the connection between the side plate 52 and the push plate 55 and improves installation efficiency.

[0049] like Figure 1 As shown, the mechanical truss 5 has multiple vertically arranged support rods 56 and a sliding longitudinal rod 57 connected to the upper end of all the support rods 56. Sliding frames 6 are slidably connected to the two sliding longitudinal rods 57, and mechanical arms 51 are connected to the sliding frames 6.
