Description

Technical Field

[0001] This utility model relates to the field of bagged material conveying technology, and specifically to a bag-handling and conveying device for bagged materials. Background Technology

[0002] During the blood product packaging process, empty bags (bag-shaped materials) need to be placed on the conveyor belt as required, and the bag-shaped materials must be in the same position and not overlap before entering the next production stage, such as the peeling process before filling and packaging.

[0003] Due to the irregular and unique nature of blood product packaging bags, manual placement of materials is inefficient, results in poor material consistency, and is physically demanding, posing a safety risk of hand pinching. Existing conveyor belts move at a uniform speed in a specific direction, only transporting materials and not adjusting their position or orientation. Inconsistent material positioning can lead to low efficiency in subsequent stripping units, reducing overall work efficiency and increasing production costs. Therefore, to reduce labor intensity, mitigate safety risks, and improve production efficiency, it is necessary to design a bag-sorting and conveying device for packaged materials.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] This utility model provides a bag-handling and conveying device for bagged materials, such as... Figure 1 As shown, it includes a feeding mechanism 1, a primary differential transmission component 2, a secondary differential transmission component 3, a transition steering component 4, a gripping transmission component 5, and a return conveyor belt 6; the primary differential transmission component 2, the secondary differential transmission component 3, the transition steering component 4, the gripping transmission component 5, and the return conveyor belt 6 are arranged in a "U" shape.

[0028] The feeding mechanism 1 connects to the primary differential transmission component 2. The primary differential transmission component 2 has a primary guide separation baffle 22 at its end, which is angled to the transmission direction of the primary differential transmission component. The end of the primary differential transmission component 2 connects to the secondary differential transmission component 3. The end of the secondary differential transmission component 3 has a secondary guide separation baffle 32, which is angled to the transmission direction of the secondary differential transmission component. The end of the secondary differential transmission component 3 connects to the transition steering component 4. The end of the transition steering component 4 connects to the gripping conveyor component 5. Component 5 includes a gripping conveyor belt 51, with a vision inspection unit 52 and a robotic transfer unit 53 arranged sequentially above the gripping conveyor belt 51. A downstream equipment conveyor belt 7 is arranged on one side of the gripping conveyor belt 51, and the end of the gripping conveyor belt 51 is connected to a return conveyor belt 6, the end of which is connected to a feeding mechanism 1. The vision inspection unit 52 is used to acquire the position and posture information of the bag-shaped material, and the robotic transfer unit 53 is used to grip the bag-shaped material and transfer it to a designated position. The return conveyor belt 6 is used to transfer the bag-shaped material that the robotic transfer unit 53 did not grip back to the feeding mechanism 1 for re-sorting.

[0029] Furthermore, the feeding mechanism 1 includes a storage bin 11 and an inclined conveyor belt 12. The storage bin 11 has a feeding port at the top and a discharge port at the bottom. The head of the inclined conveyor belt 12 is located directly below the discharge port of the storage bin 11, and the end connects to the primary differential transmission assembly 2. Preferably, the storage bin 11 has a telescopic column at its bottom, and the height of the storage bin 11 is adjustable. More preferably, the bottom of the storage bin 11 is hinged to the top of the telescopic column, and the discharge angle of the storage bin is adjustable. The adjustable height and angle of the storage bin conform to ergonomics, and the entire process of material handling and transmission is automated, greatly reducing the workload of workers.

[0030] Furthermore, the inclined conveyor belt 12 is equipped with partitions 13, which are evenly spaced along the conveying direction and the spacing is adjustable. Preferably, the distance between adjacent partitions 13 is 1.1 to 1.3 times the length of the bag-shaped material, and the height of the partition 13 is 0.6 to 0.8 times the height of the bag-shaped material, to achieve orderly output of the bag-shaped material. The bag-shaped material is manually added from the upper feed port of the storage silo 11 and automatically discharged from the lower discharge port of the storage silo 11 under the action of gravity. The bag-shaped material can achieve "first-in, first-out" in the storage silo 11, avoiding long-term material retention.

[0031] Furthermore, the primary differential speed conveyor assembly 2 is composed of several primary conveyor belts 21 arranged side by side. Along the direction of the primary guide separation baffle 22, the speeds of adjacent primary conveyor belts 21 increase sequentially. Preferably, the speed difference between adjacent primary conveyor belts 21 in the primary differential speed conveyor assembly 2 is 0.1–0.3 m / s to achieve effective separation of bagged materials. Preferably, the head end of the primary guide separation baffle 22 is movably connected to the outer perimeter of the primary differential speed conveyor assembly 2, and the end is hinged to a primary outlet baffle 23. The primary outlet baffle 23 is parallel to the conveying direction of the primary conveyor belts 21. The primary guide separation baffle 22 is a telescopic baffle, and the angle between the primary guide separation baffle 22 and the primary conveyor belts 21 is adjustable, which can change the component velocity of the bagged material along the primary guide separation baffle on the primary conveyor belt, thus dispersing the bagged material. Preferably, the angle adjustment range is 15°–45° to accommodate different types and sizes of bagged materials.

[0032] The secondary differential speed conveyor assembly 3 consists of several secondary conveyor belts 31 arranged side by side. Along the direction of the secondary guide separation baffle 32, the speeds of adjacent secondary conveyor belts 31 increase sequentially. Preferably, the speed difference between adjacent secondary conveyor belts in the secondary differential speed conveyor assembly 3 is 0.05–0.2 m / s. Preferably, the head end of the secondary guide separation baffle 32 is movably connected to the outer perimeter of the secondary differential speed conveyor assembly 3, and the end is hinged to a secondary outlet baffle 33. The secondary outlet baffle 33 is parallel to the conveying direction of the secondary conveyor belts 31. The secondary guide separation baffle 33 is a telescopic baffle, and the angle between the secondary guide separation baffle 32 and the secondary conveyor belts 31 is adjustable. This allows for changing the component speed of the bagged material along the secondary guide separation baffle 32 on the secondary conveyor belts 31, thus shaping and sorting the bagged material to ensure uniform distribution, consistent posture, and no stacking of the bagged material on the secondary conveyor belts 32. The primary differential transmission component 2 and the secondary differential transmission component 3 employ optimized and reasonable automatic acceleration and deceleration control to reduce inertia during equipment startup and shutdown, thereby better protecting the integrity of bagged materials.

[0033] The transition steering component 4 has a steering angle of 90° and a radius of curvature of 1-2m, and is used to further accurately sort and organize bagged materials.

[0034] The visual detection unit 52 includes an image acquisition module and a data processing module. The image acquisition module includes a camera, which is used to identify and determine the placement posture of the bagged material. The data processing module analyzes the posture, angle, and coordinate information of the bagged material based on the data acquired by the image acquisition module and sends it to the robotic transfer unit 53. The robotic transfer unit 53 decides whether to transfer the bagged material from the gripping conveyor belt 51 to the downstream equipment conveyor belt 7 based on the received information. Preferably, the downstream equipment conveyor belt 7 is equipped with a posture detection sensor. The posture detection sensor is communicatively connected to an alarm device and a display screen device. The posture detection sensor is used to detect the bagged material's placement posture in real time and send the detection results to the alarm device and the display screen device. For bagged materials whose placement posture does not match the requirements or which fail to be placed successfully, the alarm device will issue an audible and visual alarm to prompt the operator to check and judge the situation, so as to ensure that the bagged material is correctly placed and to ensure the smooth operation of the downstream equipment conveyor belt.

[0035] The return conveyor belt 6 has a transmission speed of 0.2-0.5 m / s and is used to stably return bagged materials that have not been grasped by the robotic arm transfer unit 53 to the feeding mechanism 1.

[0036] This utility model's bag conveying device pours bagged materials from above the storage bin 11 and conveys them out from below, following a "first-in, first-out" principle to avoid prolonged stagnation. The inclined conveyor belt 12 is designed with baffles 13, the spacing of which is slightly larger than the length of a single bag, ensuring that only one row of bags is conveyed at a time. The bagged materials fall onto the primary differential conveyor belt assembly 2 via the inclined conveyor belt 12. The speeds of adjacent belts on the primary conveyor belt increase sequentially. Under the action of the primary guide separation baffles, the stacked bagged materials are dispersed. Further, the bagged materials are oriented and sorted on the secondary differential conveyor belt assembly, ensuring uniform distribution, consistent orientation, and no stacking of the bagged materials on the conveyor belt. To improve the success rate of the robotic arm's gripping, the speed settings between the conveyor belts are adjustable. The transition steering assembly 4 and the gripping conveyor assembly 5 are set with differential speeds, making the separation of bagged materials more thorough. The transition steering assembly 4 adopts an arc-shaped turning transmission belt design to ensure that the bagged materials pass smoothly without stacking. After the bagged materials are further spaced under differential speed, they enter the gripping and conveying assembly 5. The vision detection unit 52 can identify and judge the placement posture and coordinate information of the bagged materials in real time and transmit it to the robotic gripping unit 53 in a timely manner. The robotic gripping unit 53 adjusts the posture and angle of the robotic arm according to the transmitted information to grip the bagged materials on the gripping conveyor belt 51 and place the bagged materials on the downstream equipment conveyor belt 7. At the same time, the robotic gripping unit 53 can also adjust the posture of the bagged materials as needed. The return conveyor belt 6 returns the ungrabbed bagged materials to the feeding mechanism to avoid accidental drop of ungrabbed bagged materials. The posture detection sensor on the downstream equipment conveyor belt 7 monitors the position and posture of the bagged materials in real time and sends the detection results to the alarm device and display device. If bagged materials are found to be in a posture that does not meet the requirements or have failed to be successfully gripped, an audible and visual alarm will be triggered to prompt the operator to check and judge the situation.

[0037] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
