Description

Technical Field

[0001] This utility model relates to the field of soft bag detection technology, and in particular to a soft bag body detection mechanism. Background Technology

[0002] Flexible bags, as a common type of flexible packaging container, are widely used in medical (e.g., infusion bags, peritoneal dialysis bags) and food (e.g., juice, sauces) fields due to their ease of transportation, storage, and use. Whether for medical or food applications, the seal integrity of flexible bags is a key indicator for ensuring the sterility of the contents, preventing spoilage, and ensuring user safety. If a flexible bag leaks, the contents may become contaminated with microorganisms or undergo chemical changes, directly endangering the user's health and life. Therefore, before flexible bags are put on the market, they must undergo rigorous seal testing. Currently, the market demand for flexible bag seal testing is growing, especially for efficient, automated equipment capable of 100% inspection. However, there is a significant gap in the current field of fully automated flexible bag testing equipment; many testing steps still rely on manual or semi-automated equipment, resulting in low efficiency, poor consistency, and a high risk of missed detections.

[0003] Existing technology discloses a soft bag inspection device and method. Patent application CN118616354A discloses a soft bag inspection device including an inclined conveyor line for transporting soft bags. The inclined conveyor line includes an upper inclined conveyor mechanism and a lower inclined conveyor mechanism. The upper inclined conveyor mechanism has at least one light inspection station and / or a leak detection module, and the lower inclined conveyor mechanism has at least one light inspection station and / or a leak detection module. Related technologies, including the above-mentioned technical solutions, still have many problems, such as: ① During the production of soft bags, the surface of the soft bag is not flat. The sealing edges and grooves created by forming and filling the bag body can lead to insufficient contact between the detection brush and the bag surface, forming a blind spot and easily causing missed detections; ② Existing technologies using upper or lower inclined conveyor mechanisms, because the soft bags are placed along the conveyor line during transport, are prone to missed detections for cases where the soft bag edges are rolled or deformed, resulting in poor detection accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a soft bag body detection mechanism to solve the technical problems of poor detection accuracy and missed detection caused by grooves or rolled edges of the soft bag body in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soft bag body inspection mechanism, comprising:

[0007] The first bag body detection component is used to tilt and convey the bag to be detected so that its left half is filled with liquid, so as to detect the left half and left side of the bag body;

[0008] The second bag body detection component is used to tilt and convey the bag to be detected so that its right half is filled with liquid, so as to detect the right half and right side of the bag body.

[0009] The first bag body detection component and the second bag body detection component are connected end to end to achieve continuous conveying. Both the first bag body detection component and the second bag body detection component include a brush detection component for detecting the conveyed bag body. The direction of the movement of the conductive brush of the brush detection component is consistent with the extension direction of the left and right sides of the soft bag.

[0010] Furthermore, the first bag body detection component includes a first front conveyor belt and a first rear conveyor belt, which are connected end to end and have a gap between them. A first brush detection component is provided at the gap, which is used to detect the left half and left side of the bag body passing through the gap.

[0011] Furthermore, the upper surfaces of the first front conveyor belt and the first rear conveyor belt are both inclined, and a first guide plate is provided on the side with the lower height. The first guide plate is used to slide against the left half of the bag body passing through the first front conveyor belt and the first rear conveyor belt to guide it and ensure that the left half of the bag body is filled with liquid.

[0012] Furthermore, the second bag body detection component includes a second front conveyor belt and a second rear conveyor belt, which are connected end to end and have a gap between them. A second brush detection component is provided at the gap, which is used to detect the right half and right side of the bag body passing through the gap.

[0013] Furthermore, the upper surfaces of the second front conveyor belt and the second rear conveyor belt are both inclined, and a second guide plate is provided on the side with the lower height. The second guide plate is used to slide against the right half of the bag body passing through the second front conveyor belt and the second rear conveyor belt to guide it and ensure that the right half of the bag is filled with liquid. The inclination directions of the second front conveyor belt and the first rear conveyor belt are opposite.

[0014] Furthermore, the first front conveyor belt and the first rear conveyor belt have the same inclination angle α, and the second front conveyor belt and the second rear conveyor belt have the same inclination angle β. Here, the direction of counterclockwise rotation is defined as positive above the horizontal plane and negative below the horizontal plane, where α > 0° > β and α = -β.

[0015] Furthermore, the brush detection assembly includes a vertical plate and two horizontal connecting rods connected to both ends of the connecting rod. An upper conductive brush and a lower conductive brush are respectively installed on the ends of the two horizontal connecting rods away from the vertical plate. An adjustable upper fixed seat and a lower fixed seat are respectively installed on the two horizontal connecting rods. The upper fixed seat and the lower fixed seat are respectively fixedly installed relative to the frame.

[0016] Furthermore, the frame includes several support rods and side plates. The side plates are fixedly installed relative to the top of the support rods. Several sets of main conveyor rollers and driven conveyor rollers are rotatably installed between the two side plates. A rotary conveyor belt is installed between the main conveyor rollers and driven conveyor rollers. The main conveyor rollers are driven to rotate by a drive unit.

[0017] Furthermore, a transition conveyor belt is provided at the entrance of the first front conveyor belt. The inclination direction and inclination angle of the transition conveyor belt are consistent with those of the first front conveyor belt. The first guide plate extends from the entrance of the transition conveyor belt to the exit of the first rear conveyor belt.

[0018] Furthermore, the drive unit includes a transition drive unit, a first drive unit, and a second drive unit. The transition drive unit is used to drive the transition conveyor belt to run, the first drive unit is used to drive the first front conveyor belt and the first rear conveyor belt to run, and the second drive unit is used to drive the second front conveyor belt and the second rear conveyor belt to run.

[0019] Furthermore, both the first guide plate and the second guide plate are connected to the positioning block via a horizontal support rod, and the positioning block is mounted on the side plate.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] (1). This utility model sets up a first bag body detection component and a second bag body detection component to transport the bag body to be tested at different angles. Unlike the existing technology, which uses uphill and downhill transport to fill the upper and lower halves of the bag body with liquid for detection, this application adopts a scheme to fill the left and right sides of the bag body with liquid for detection. This ensures that the filaments of the conductive brush are consistent with the extension direction of the left and right sides of the soft bag, thereby avoiding the situation of missed detection caused by uneven contact of the conductive brush due to the side edge curling or grooves of the bag body. This is beneficial to improving the detection accuracy.

[0022] (2). By setting a first guide plate and a second guide plate, which are respectively used in conjunction with their respective conveyor belts, this utility model can achieve the tilted conveying of the bag to be tested while ensuring the positional accuracy of the bag. In turn, it can cooperate with the brush detection component to complete the detection operation, which greatly improves the detection accuracy. Attached Figure Description

The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0037] This utility model primarily addresses the common problems in existing equipment for inspecting soft bags, such as uneven surface due to rolled edges or grooves caused by being filled with liquid during bag processing, air bubbles appearing inside the soft bag during processing, leading to insufficient contact between the brush and the bag surface during inspection and resulting in poor detection accuracy, as well as the inability to detect the hollow parts of the soft bag. This application provides technical improvements to address these deficiencies, specifically as follows:

[0038] See appendix Figure 1 and 2A soft bag body detection mechanism includes: a frame, a first bag body detection component and a second bag body detection component mounted on the frame. The first bag body detection component and the second bag body detection component are connected end to end to achieve continuous conveying. Both the first bag body detection component and the second bag body detection component include an electric brush detection component for detecting the conveyed bag body. The direction of the movement of the conductive brush of the electric brush detection component is consistent with the extension direction of the left and right sides of the soft bag. The electric brush detection component includes a first electric brush detection component 400 and a second electric brush detection component 401. The end-to-end connection here can be understood as the soft bag being detected by the first bag body detection component and then being conveyed directly into the second bag body detection component for further detection. It should be noted that the left and right sides of the soft bag refer to the symmetrical division on both sides with the center line of the soft bag head as the boundary. One side is the left half and the other side is the right half. The left half and the right half are the two sides of the soft bag. The frame includes several support rods 100 and side plates 101. The side plates 101 are fixedly installed relative to the top of the support rods 100. Several sets of main conveyor rollers and driven conveyor rollers are rotatably installed between the two side plates 101. A rotary conveyor belt is installed between the main conveyor rollers and driven conveyor rollers. The main conveyor rollers are driven to rotate by a drive unit. It can be understood that there are two rows of support rods 100, and several side plates 101 are installed on the top of each row of support rods 100. Several sets of independently operating conveyor belts are installed between the two rows of side plates 101.

[0039] See appendix Figure 3The first bag body detection component is used to tilt and convey the bag to be tested so that its left half is filled with liquid, so as to detect the left half and left side of the bag body. It can be understood that the tilted conveying causes the air bubble to slide naturally to the right and higher, avoiding the problem that this cavity cannot be detected. Specifically, the first bag body detection component includes a first front conveyor belt 300 and a first rear conveyor belt 500. The first front conveyor belt 300 and the first rear conveyor belt 500 are connected end to end and there is a gap between them. A first brush detection component 400 is set at the gap. The first brush detection component 400 is used to detect the left half and left side of the bag body that pass through the gap. Specifically, the upper surfaces of the first front conveyor belt 300 and the first rear conveyor belt 500 are both inclined, and a first guide plate 102 is provided on the side with the lower height. This first guide plate 102 is used to slide against the left half of the bag body passing through the first front conveyor belt 300 and the first rear conveyor belt 500 to guide it and ensure that the left half is filled with liquid. The purpose of this inclined conveying is to ensure that when the soft bag is conveyed under its own weight, the side of the soft bag to be detected contacts the first guide plate 102 to adjust the position of the soft bag, so that the first brush detection assembly 400 can fully contact the soft bag. In addition, it helps to keep air bubbles away from the side to be detected, thereby improving detection accuracy. It can be understood that the inclined setting of the first front conveyor belt 300 and the first rear conveyor belt 500 is adjusted by the length of the support rod 100. The length of the support rod 100 on the lower side is smaller, and the length of the support rod 100 on the higher side is larger, thereby realizing the angle adjustment of the first front conveyor belt 300 and the first rear conveyor belt 500.

[0040] See appendix Figure 4 The second bag body detection component is used to tilt and convey the bag to be tested so that its right half is filled with liquid, so as to detect the right half and right side of the bag body. It can be understood that the tilted conveying causes the air bubbles to slide naturally to the left and higher, avoiding the problem of this cavity being undetectable. Specifically, the second bag body detection component includes a second front conveyor belt 600 and a second rear conveyor belt 700. The second front conveyor belt 600 and the second rear conveyor belt 700 are connected end to end and there is a gap between them. A second brush detection component 401 is set at the gap. The second brush detection component 401 is used to detect the right half and right side of the bag body passing through the gap. Specifically, the upper surfaces of the second front conveyor belt 600 and the second rear conveyor belt 700 are both inclined, and a second guide plate 103 is provided on the side with the lower height. The second guide plate 103 is used to slide against the right half of the bag body passing through the second front conveyor belt 600 and the second rear conveyor belt 700 to guide it and ensure that the right half of it is filled with liquid. The inclination directions of the second front conveyor belt 600 and the first rear conveyor belt 500 are opposite. The purpose of the opposite inclination directions of the second front conveyor belt 600 and the first rear conveyor belt 500 is to conduct comprehensive inspection of both sides of the soft bag.

[0041] See appendix Figure 2 The first front conveyor belt 300 and the first rear conveyor belt 500 have the same inclination angle, α. The second front conveyor belt 600 and the second rear conveyor belt 700 have the same inclination angle, β. Here, the direction is defined as counterclockwise, with values ​​above the horizontal plane being positive and values ​​below the horizontal plane being negative, where α > 0° > β and α = -β. Preferably, α = 5° to 10°, and α = 5°. It can be understood that the fact that the first front conveyor belt 300 and the second front conveyor belt 600 have the same inclination angle means that they are symmetrically arranged vertically along the horizontal plane.

[0042] See appendix Figure 5 The brush detection assembly includes a vertical plate 402 and two horizontal connecting rods 405 connected to both ends of a connecting rod. An upper conductive brush 407 and a lower conductive brush 406 are respectively installed on the ends of the two horizontal connecting rods 405 away from the vertical plate 402. An adjustable upper fixing seat 403 and a lower fixing seat 404 are respectively installed on the two horizontal connecting rods 405, and are fixedly mounted relative to the frame. It can be understood that the connections between the upper fixing seat 403 and the lower fixing seat 404 and the horizontal connecting rods 405 are secured with screws. The installation positions of the upper fixing seat 403 and the lower fixing seat 404 on the horizontal connecting rods 405 can be adjusted as needed. The positions of the upper conductive brush 407 and the lower conductive brush 406 on the horizontal connecting rods 405 are adjusted through elongated holes on the upper conductive brush 407 and the lower conductive brush 406.

[0043] See appendix Figure 1 and 6 The first guide plate 102 and the second guide plate 103 are both connected to the positioning block 1022 via a horizontal support rod 1021, which is mounted on the side plate 101. It is understood that the mounting position of the positioning block 1022 on the horizontal support rod 1021 can be adjusted as needed.

[0044] See appendix Figure 1A transition conveyor belt 200 is also provided at the inlet of the first front conveyor belt 300. The inclination direction and inclination angle of the transition conveyor belt 200 are the same as those of the first front conveyor belt 300. The first guide plate 102 extends from the inlet of the transition conveyor belt 200 to the outlet of the first rear conveyor belt 500. In addition, the drive unit includes a transition drive unit 800, a first drive unit 801, and a second drive unit 802. The transition drive unit 800 drives the transition conveyor belt 200, the first drive unit 801 drives the first front conveyor belt 300 and the first rear conveyor belt 500, and the second drive unit 802 drives the second front conveyor belt 600 and the second rear conveyor belt 700. The transition drive unit 800, the first drive unit 801, and the second drive unit 802 all use rotary motors. The transition conveyor belt 200 is designed to facilitate the inclined conveying of soft bags falling onto it, ensuring they contact the first guide bar.

[0045] When using this invention to inspect soft bags, the soft bag is conveyed to the transition conveyor belt 200 after the previous process. Due to the inclined setting of the transition conveyor belt 200, the soft bag slides down to the side and contacts the first guide plate 102 under its own weight. When the soft bag is conveyed to the gap between the first front conveyor belt 300 and the first rear conveyor belt 500, the first brush detection component 400 detects the left side and left edge of the bag. The soft bag continues to be conveyed to the second front conveyor belt 600 and then to the gap between the second front conveyor belt 600 and the second rear conveyor belt 700. The second brush detection component 401 detects the other side of the soft bag, namely the right side and right edge. Since the direction of the movement of the conductive brush bristles is consistent with the extension direction of the left and right sides of the soft bag, the problem of insufficient contact between the conductive brush and the soft bag due to the curling or grooves of the soft bag can be avoided, thereby improving the detection accuracy.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
