Description

Technical Field

[0001] This utility model relates to the field of packaging device technology, and more specifically, to a synchronous belt-type bone strip bag image buffer device. Background Technology

[0002] Currently, most ribbed bag buffer feeding devices on the market suffer from the following technical defects: First, the equipment has poor compatibility and is difficult to adapt to the feeding needs of ribbed bags of different specifications; second, it is difficult to guarantee the consistency of bag feeding position, especially when processing packaging bags with ribbed structures, as the uneven stacking height of the ribs leads to deviations in the suction position; third, the capacity design of existing single-station buffer devices is unreasonable, typically only able to maintain production needs for 5 minutes, requiring frequent manual replenishment by operators, which seriously affects production efficiency. More significantly, when the number of ribbed bags stacked in traditional material boxes reaches around 100, the ribs form a distinct stepped stacking, causing inaccurate positioning of the bags within the material box and frequently resulting in residual material that cannot be completely removed. These problems manifest as: the suction cup's inability to accurately capture the bag tail position during ribbed bag suction, poor consistency in feeding position, and systemic defects such as production line interruptions caused by excessively short replenishment intervals. Utility Model Content

[0003] This utility model discloses a synchronous belt-type bone strip bag image upper bag buffer device, which aims to solve the above-mentioned problems.

[0004] The present invention adopts the following solution: A synchronous belt type image loading and buffering device for bone strip bags includes: a synchronous belt with multiple segmented attachments, the segmented attachments being adapted to restrict the two sides of the bone strip bag to prevent the bone strip bag from tilting; an image positioning unit disposed above the synchronous belt for identifying the posture of the uppermost bone strip bag in the loading station; and a loading mechanism configured to pick up the bone strip bag according to its posture to keep the picking position consistent.

[0005] Furthermore, a photoelectric sensor is installed at the bag-loading station to identify the rib bags in the supply compartment at the bag-loading station to confirm whether there is a shortage of material.

[0006] Furthermore, a light source assembly is provided on one side of the upper bag station, the light source assembly including two complementary light sources that are tilted relative to each other to form an "eight" shape.

[0007] Furthermore, the image positioning unit includes an aluminum profile frame and a camera lens disposed above the aluminum profile frame, the camera lens being adapted to move and adjust within the aluminum profile frame.

[0008] Furthermore, the synchronous belt is driven by a servo motor.

[0009] Furthermore, the bag-loading mechanism employs a bag-loading robot arm.

[0010] Furthermore, the segmented attachment is adapted to form multiple receiving cavities on the synchronous belt with the baffles disposed on both sides of the synchronous belt for placing the bone strip bag; the bottom of the receiving cavity is provided with a receiving groove and a slope at the bone strip end position of the bone strip bag, so that the bone strip end of the bone strip bag is biased downward in the receiving cavity.

[0011] Furthermore, the bottom of the receiving cavity is provided with an elastic floating tray to maintain the top surface of the top bag at a predetermined height.

[0012] Beneficial effects: 1. The relative position of the bone strip bag is identified by image capture and the position information is output to the bag-loading robot, which ensures the consistency of the bag-loading robot's suction position; 2. The synchronous conveyor belt design with segmented attachments is adopted, which ensures that each segment of the bone strip bag can be fully filled without any leftover material, thus solving the problem of unstable bag feeding.

[0013] 3. A photoelectric sensor is installed to detect the presence or absence of bags, which can alert personnel in advance to replenish materials. Attached Figure Description

[0015] Combination Figure 1 This embodiment provides a synchronous belt type image loading and buffering device for bone strip bags, including: a synchronous belt 1 with multiple segmented attachments 2, the segmented attachments 2 being adapted to restrict the two sides of the bone strip bag to prevent the bone strip bag from tilting; an image positioning unit above the synchronous belt 1, used to identify the posture of the uppermost bone strip bag in the supply grid located at the loading station; and a loading mechanism (not shown), configured to pick up the bone strip bag according to its posture to keep the picking position consistent.

[0016] Among them, the segmented attachment 2 refers to the limiting components spaced at intervals along the length of the synchronous belt 1, which can be implemented using L-shaped metal buckles, with its vertical side forming a right-angle constraint with the running direction of the synchronous belt 1. The image positioning unit refers to a vision system with three-dimensional spatial detection capabilities, which can be implemented using an industrial camera in conjunction with an adjustable bracket, and can be adjusted to adapt to the detection needs of bags of different sizes. The bag loading mechanism refers to an adsorption device with position feedback, which can be implemented using a vacuum suction cup in conjunction with a servo drive module, and coordinate compensation ensures that the suction point is aligned with the center of the bag.

[0017] When synchronous belt 1 operates, it drives segmented attachment 2 to form a continuous supply unit. Each segmented unit is constrained by side limiters to prevent lateral displacement of the bag. When the segmented unit moves to the upper bag station, the vision system performs a 3D scan of the stacked bags, calculating the center coordinates and tilt angle of the top bag. The host computer generates coordinate compensation commands based on the vision data, driving the suction device of the upper bag mechanism to adjust the planar coordinates and angular offset of the vacuum suction cup, ensuring that each suction action is performed on the preset position of the bag. Preferably, a sloped structure set at the bottom of the segmented unit guides the bone strip end to sink naturally, eliminating the height accumulation effect during the stacking process. This solution achieves active control of the bag stacking shape through the coordinated action of dynamic synchronous belt 1 segmentation and bottom slope, combined with servo drive to achieve precise position compensation.

[0018] In this embodiment, a photoelectric sensor 9 is installed at the bag-loading station. The photoelectric sensor 9 is used to identify the rib bags in the supply compartment at the bag-loading station to confirm whether there is a shortage of material. The photoelectric sensor 9 can be implemented using an infrared transmitter-receiver pair or a laser sensor. Its installation position is located above or to the side of the supply compartment. It determines whether there is material in the compartment by monitoring whether the light path is blocked by the rib bags. The photoelectric sensor 9 outputs a signal to determine whether the rib bags in the supply compartment are exhausted, avoiding situations where the robot arm sucks up empty or the equipment runs idle due to a shortage of material.

[0019] In a preferred embodiment, a light source assembly 5 is provided on one side of the upper bagging station. The light source assembly 5 includes two relatively tilted supplementary light sources forming a figure-eight shape. The installation position and angle of the light source assembly 5 must ensure that the light covers the surface of the ribbed bag. The supplementary light source refers to a light source with a specific illumination direction, which can be implemented using a linear light source with an tilt angle of 30°-60°. The two light sources are symmetrically distributed on both sides of the upper bagging station, forming a cross-illumination area to eliminate shadow interference on the surface of the ribbed bag. When the image positioning unit performs posture recognition on the ribbed bag, the cross light can cover the area where the ribbed end of the ribbed bag connects to the bag body, avoiding local reflections or shadow occlusion caused by unilateral illumination. For example, the tilt angle of the supplementary light source can be set to 45°, at which point the light can evenly cover the uneven surface of the stacked ribbed bags, ensuring that the camera captures clear contour features.

[0020] The image positioning unit described in this embodiment includes an aluminum profile frame 7 and a camera lens 8 disposed above the aluminum profile frame 7. The camera lens 8 is adapted to move and adjust within the aluminum profile frame 7. The camera lens 8 can be fixed to the mounting base by a quick-release clamp, and the operator can adjust the coordinate position of the camera in the horizontal plane along the aluminum profile guide rail. In a preferred embodiment, when the stacking posture of the bone strip bags changes, the camera can be moved so that its optical axis is aligned with the center area of ​​the target bag, ensuring that the image acquisition area covers the effective feature parts of the bone strip bag.

[0021] In this embodiment, the synchronous belt 1 is driven by a servo motor 6. The servo motor 6 drives the synchronous belt 1 to move the segmented attachment 2, so that each supply segment can accurately stop at the bag-loading station according to a preset step distance. Here, each receiving cavity 3 of the synchronous belt 1 can hold 100 bone strip bags, which is exactly the number of one stack of bone strip bags. The buffer capacity of the entire synchronous belt 1 can meet the client's need to replenish materials once every 1.5 hours. Through the image positioning detection system, the position of the top layer of bone strip bags is output each time, and then the position positioning information is output to the bag-loading robot to meet the requirements of consistent bone strip bag picking position and consistent feeding position. At the same time, since it is a single-station feeding mode and the number of bags is moderate, it can be ensured that each segment of material can be stably polished without leaving any excess material, so that the replenishment interval can be effectively guaranteed.

[0022] Combination Figure 1 and Figure 2As shown, in a preferred embodiment, the compartment attachment 2 is adapted to form multiple receiving cavities 3 on the synchronous belt 1 with the baffles disposed on both sides of the synchronous belt 1 for placing the bone strip bags; the bottom of the receiving cavity 3 is provided with receiving grooves 4 and inclined surfaces 10 at the bone strip ends of the bone strip bags, so that the bone strip ends of the bone strip bags are biased downward within the receiving cavity 3. Here, the receiving groove 4 refers to the recessed area located at the bottom of the receiving cavity 3, the depth of which can be set to be slightly greater than the thickness of the bone strip end; the inclined surface 10 refers to the wedge-shaped slope formed from low to high from the bone strip end to the bag tail end on the support surface of each receiving cavity, so that the bone strip end is naturally lower than the bag tail end. After stacking in this way, the bag tail of the top layer bag is higher and more exposed, which is convenient for image recognition edges and the lower nozzle. Specifically, a slope structure with an inclination angle of 15-30 degrees can be used to guide the bone strip ends to sink. When the bone strip bag is placed in the receiving cavity 3, the bone strip ends are embedded into the receiving grooves 4 under the action of gravity, and the inclined surface 10 forces the bone strip ends to continue to slide downward until they are completely in contact with the bottom of the groove. This structure ensures that the bone strip ends of the bag consistently face the recessed groove during stacking, preventing the bag from tilting due to the bone strip ends sticking up. During the operation of the synchronous belt 1, the enclosed space formed by the baffle and the dividing attachment 2 prevents the bone strip bag from shifting due to inertial forces. Through the synergistic effect of the accommodating groove 4 and the inclined surface 10, the bone strip ends automatically sink and align during stacking, eliminating suction failures caused by differences in bone strip end height. This ensures that the bone strip bag maintains a fixed bone strip end position during buffering, guaranteeing that the bag's position deviates from the preset coordinates within the mechanical repeatability accuracy range for each suction operation. This structure effectively solves the problem of suction cups missing bag tails due to uncontrolled stacking height of the bone strip ends, while also eliminating the need for frequent manual adjustments to the bag's position.

[0023] In another preferred embodiment, an elastic floating tray (not shown) is provided at the bottom of the receiving cavity 3 to maintain the top surface of the top bag at a predetermined height. The elastic floating tray is a load-bearing structure with elastic support function set at the bottom of the receiving cavity 3. Specifically, it can be implemented using a spring-supported metal plate, adapting to changes in the stacking height of the boned bags through elastic deformation. The predetermined height refers to a fixed plane position that matches the suction position of the upper bag mechanism. This can be achieved by adjusting the initial compression of the elastic floating tray, ensuring that the top boned bag is always within a stable suction range. As the number of boned bags in the receiving cavity 3 gradually decreases, the elastic floating tray rises under the action of elastic restoring force, ensuring that the top layer of the remaining boned bags is always in close contact with the opening plane of the receiving cavity 3. When the number of stacked boned bags reaches its maximum value, the elastic floating tray is compressed to its lowest position, at which point the depth of the receiving cavity 3 matches the stacking height. Through this structure, regardless of the change in the number of boned bags in the receiving cavity 3, the relative height between the boned end of the top bag and the suction mechanism remains constant. The dynamic compensation of the flexible floating tray eliminates the impact of stacking height changes on the suction operation, avoids the problem of leakage caused by the sinking of the bag tail, and effectively solves the problem of unstable top layer height caused by the accumulation of thickness at the bone strip end during the stacking of bone strip bags.

[0024] The above-described embodiments improve bagging efficiency and ensure consistency in each bagging process.
