Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a defective product rejection device for bagged materials. Background Technology

[0002] Currently, the industry widely uses automated devices based on vision inspection technology for defective inspection and rejection of bagged materials. Existing vision inspection modules typically only have a vision inspection component installed above the conveyor line, and can only inspect the single surface of the bagged material facing the inspection component. However, defects in bagged materials may appear on both opposite sides (such as printing errors on the front or broken seals on the back), and single-sided vision inspection cannot cover the need for double-sided inspection of the material.

[0003] To achieve comprehensive inspection of both sides of bagged materials and ensure no potential quality issues are overlooked, technicians often employ a layout where two vision inspection modules are sequentially positioned above the conveyor line along the material transport direction, with a flipping component between them to turn the bagged materials over. However, this common layout has drawbacks. Positioning two vision inspection modules and a flipping component sequentially along the transport direction results in the vision inspection module occupying a significant amount of space along the length and / or width of the conveyor line, thus increasing the footprint of the defective product rejection device or the entire bagged material production line within the factory.

[0004] Many small and medium-sized factories face the reality of limited factory space, and multiple production lines for the same product often operate simultaneously within the same factory. When a factory adds a new production line for a new product or upgrades the equipment on a production line for a certain product (such as bagged materials), it often needs to make large-scale adjustments to the layout of the existing factory, and may even need to lease or expand additional factory space. This undoubtedly increases the company's production costs and the difficulty of production planning. Utility Model Content

[0005] The main purpose of this invention is to provide a bag-shaped material defect removal device, which aims to provide a bag-shaped defect removal device with a small footprint.

[0006] To achieve the above objectives, the present invention proposes a defective bag-shaped material rejection device for a conveyor line transporting bag-shaped materials, comprising:

[0007] A visual inspection module, located near the end of the conveyor line, includes a detection and conveying assembly located on the conveyor line, a first detection assembly located above the conveyor line, and a second detection assembly located below the conveyor line. The conveyor line has a first detection station corresponding to the first detection assembly and a second detection station corresponding to the second detection assembly. The detection and conveying assembly conveys the bagged material at the first detection station to the second detection station. The first and second detection assemblies respectively inspect opposite sides of the bagged material.

[0008] The rejection module is located on the side of the vision inspection module near the end of the bag material conveyor line, and is used to reject defective bag materials detected by the vision inspection module from the bag material conveyor line.

[0009] In one embodiment, the detection conveying assembly includes a rotating flip plate, and the rotating flip plate is provided with a connecting component to connect the bag-shaped material to the plate surface of the rotating flip plate. The rotating flip plate is used to flip the bag-shaped material and can move the bag-shaped material from the first detection station to the second detection station.

[0010] In one embodiment, the conveyor belt has a feeding station for the rejection module, the feeding station is located close to the vision detection module, and the rotating flip plate can transport the bagged material from the second detection station to the feeding station.

[0011] In one embodiment, the rotating flip plate includes a first plate extending along a first direction and a second plate extending along a second direction, the ends of the first plate and the second plate are connected, and the first direction and the second direction are perpendicular to each other. The connecting component is disposed on the side of the first plate and the second plate that are close to each other, and the rotation axis of the rotating flip plate is disposed at the intersection of the first plate and the second plate.

[0012] In one embodiment, the conveyor belt is further provided with a first flipping station and a second flipping station. The first detection station, the first flipping station and the second flipping station are arranged sequentially in the conveying direction of the conveyor belt, and the extension direction of the first flipping station is perpendicular to the extension direction of the second flipping station. The first flipping station is located above the second flipping station, and the first plate and the second plate rotate between the first detection station, the second detection station, the first flipping station and the second flipping station.

[0013] In one embodiment, the first inspection station and the second inspection station are located on opposite sides of the conveyor belt.

[0014] In one embodiment, the rotating flipping plate has a first forward rotation state, a second forward rotation state, and a first reverse rotation state. In the first forward rotation state, the first plate rotates from the first detection station to the first flipping station, and the second plate rotates from the first flipping station to the second flipping station. The connecting component on the first plate is not connected to the bag-shaped material, so that the bag-shaped material falls from the first flipping station to the second flipping station. The connecting component on the second plate is connected to the bag-shaped material.

[0015] In the second forward rotation state, the first plate rotates from the first flipping station to the second flipping station, and the second plate rotates from the second flipping station to the second detection station;

[0016] In the first reverse rotation state, the first plate rotates past the second flipping station and arrives at the first flipping station. The second plate rotates from the second detection station to the second flipping station. The rotating flipping plate is also provided with a pusher, which pushes the bag-shaped material from the second flipping station to the feeding station.

[0017] In one embodiment, the rotating flip plate further includes a third plate and a fourth plate, the third plate and the first plate being disposed opposite to each other, the fourth plate and the second plate being disposed opposite to each other, and the ends of the first plate, the second plate, the third plate and the fourth plate being connected together, and the connecting components being disposed on opposite sides of the first plate, the second plate, the third plate and the fourth plate.

[0018] In one embodiment, the rotating flip plate also has a second reverse rotation state, in which the first plate rotates from the first flip station to the first detection station, and the second plate rotates from the second flip station to the first flip station.

[0019] In one embodiment, the pusher includes an air nozzle and an air jet assembly connected to the air nozzle, and air nozzles are provided on the side of the first plate, the second plate, the third plate and the fourth plate near the rotating shaft.

[0020] In one embodiment, both the first detection component and the second detection component include a detection housing, a light source disposed in the detection housing, and a detection camera. The light source and the detection camera are both positioned facing the conveyor belt. The detection housing is provided with an avoidance opening to avoid the rotating flip plate. When the first plate is located at the first detection station, the second plate and the detection housing enclose a detection space. When the second plate is located at the second detection station, the first plate and the detection housing enclose the detection space.

[0021] In one embodiment, the connecting assembly includes a negative pressure suction hole disposed on the rotating flip plate and a negative pressure assembly connected to the negative pressure suction hole.

[0022] In one embodiment, the rejection module includes a flap, a drive unit for moving the flap, and a waste bin below the flap. The flap is positioned close to the feeding station, and a conveying assembly is provided on the upper side of the flap for conveying the bagged material along the conveying direction of the conveyor belt. The flap has a rejection position and a transport position. In the rejection position, the flap is away from the conveyor belt, and a material outlet connecting the flap and the conveyor belt to the waste bin is provided. In the transport position, the flap is close to the conveyor belt, and the bagged material is transported by the conveying assembly.

[0023] The technical solution of this utility model places the first detection component (detecting one side of the bagged material) of the visual inspection module above the conveyor line and the second detection component (detecting the opposite side) below the conveyor line. This avoids excessive extension of the device in the length or width direction, significantly reducing the overall footprint and allowing it to flexibly adapt to production scenarios with limited space, such as small and medium-sized factories, without requiring large-scale adjustments to the factory layout to introduce the equipment. This reduces the manpower and material costs associated with layout adjustments. While reducing the footprint, the detection and conveying component accurately transports the bagged material from the first detection station to the second detection station, enabling the two detection components, distributed vertically, to comprehensively inspect the opposite sides of the material. This effectively covers quality inspection dimensions such as sealing, filling volume, bag integrity, and printing patterns, avoiding sacrificing the inspection range due to layout optimization, and achieving a balance between space compactness and comprehensive inspection.

[0042] This utility model proposes a device for rejecting defective bagged materials.

[0043] Please see Figures 1 to 8 In one embodiment of this utility model, the bag-shaped material 400 defective product rejection device, used in the conveyor line 300 for conveying the bag-shaped material 400, includes:

[0044] A visual inspection module 100, located near the end of the conveyor line 300, includes a detection conveying component 21111 disposed on the conveyor line 300, a first detection component 15 disposed above the conveyor line 300, and a second detection component 16 disposed below the conveyor line 300. The conveyor line 300 has a first detection station corresponding to the first detection component 15 and a second detection station corresponding to the second detection component 16. The detection conveying component 21111 is used to convey the bag-shaped material 400 from the first detection station to the second detection station. The first detection component 15 and the second detection component 16 respectively inspect the opposite sides of the bag-shaped material 400.

[0045] The rejection module 200 is located on the side of the vision inspection module 100 near the end of the bag material 400 conveyor line 300, and is used to reject the defective bag materials 400 detected by the vision inspection module 100 from the bag material 400 conveyor line 300.

[0046] The technical solution of this utility model involves placing the first detection component 15 (detecting one side of the bagged material 400) of the visual inspection module 100 above the conveyor line 300 and the second detection component 16 (detecting the opposite side) below the conveyor line 300. This avoids excessive extension of the device in the length or width direction, significantly reducing the overall footprint and allowing it to flexibly adapt to production scenarios with limited space, such as small and medium-sized factories, without requiring large-scale adjustments to the factory layout to introduce the equipment. This further reduces the manpower and material consumption caused by layout adjustments. While reducing the footprint, the detection and conveying component 21111 accurately conveys the bagged material 400 from the first inspection station to the second inspection station, enabling the two detection components, distributed vertically, to comprehensively inspect the opposite sides of the material. This effectively covers quality inspection dimensions such as sealing, filling volume, bag integrity, and printing patterns, avoiding sacrificing the inspection range due to layout optimization, and achieving a balance between space compactness and comprehensive inspection.

[0047] In one embodiment, the inspection and conveying assembly 21111 includes a rotating flip plate 12, on which a connecting assembly 13 is provided to connect the bag-shaped material 400 to the surface of the rotating flip plate 12. The rotating flip plate 12 is used to flip the bag-shaped material 400 and can move the bag-shaped material from the first inspection station to the second inspection station. The rotating flip plate 12 can drive the material to complete a precise flip, so that the side of the material originally facing down from the conveyor line 300 is flipped to face up (or adapted to the inspection angle of the second inspection assembly 16). With the first inspection assembly 15 located above the conveyor line 300 and the second inspection assembly 16 located below it, the material can be inspected comprehensively on both sides without blind spots, effectively covering quality dimensions such as sealing, filling volume, bag integrity, and printing patterns, greatly reducing the probability of missed or false inspections due to unstable material position, and improving the accuracy of defective product identification. In other embodiments, the detection conveying assembly 21111 may include a pusher 14, and a detection box corresponding to the second detection assembly 16 is provided on the conveyor belt. The bottom plate of the detection box is made of transparent material so that the second detection assembly 16 can take pictures and detect the other side of the bag-shaped material 400. The pusher 14 can push the bag-shaped material 400 from the first detection station to the second detection station, that is, push it into the detection box.

[0048] In one embodiment, the conveyor belt has a feeding station for the rejection module 200, which is located close to the vision inspection module 100. The rotating flipper 12 can transport the bagged material 400 from the second inspection station to the feeding station. The feeding station's proximity to the vision inspection module 100 avoids the problem of traditional devices where the inspection module and rejection module 200 are far apart, requiring an additional long-distance conveying section, thus significantly shortening the overall span of the equipment along the conveyor line 300. Simultaneously, after conveying and flipping the bagged material 400, the rotating flipper 12 can directly transport the material to the adjacent feeding station without the need for a separate transitional conveying mechanism connecting the inspection module and rejection module 200, such as a short conveyor belt or guide roller assembly. This design allows the vision inspection module 100, the feeding station, and the rejection module 200 to form a compact, integrated layout, further reducing the space occupied by the equipment in the factory. In other embodiments, the detection conveying assembly 21111 may include a pushing device located on the side of the conveyor belt to push the bagged material 400 to the feeding station.

[0049] Specifically, the rotating and flipping plate 12 includes a first plate 121 extending along a first direction and a second plate 122 extending along a second direction. The ends of the first plate 121 and the second plate 122 are connected, and the first direction and the second direction are perpendicular to each other. A connecting component 13 is disposed on the adjacent sides of the first plate 121 and the second plate 122. The rotation axis of the rotating and flipping plate 12 is disposed at the intersection of the first plate 121 and the second plate 122. The vertical arrangement of the first plate 121 and the second plate 122 can be combined with the rotation angle design to achieve a 90° turn in the material conveying direction, for example, the first plate 121 turns from along the conveying line 300 to perpendicular to the conveying line 300, or completes a 180° flipping action. The connecting component 13 is disposed on the inner side of the two plates, which can realize the smooth transfer of materials between the two plates during rotation, for example, from the first plate 121 to the second plate 122.

[0050] In one embodiment, the conveyor belt is further provided with a first flipping station and a second flipping station. The first detection station, the first flipping station, and the second flipping station are arranged sequentially in the conveying direction of the conveyor belt, and the extension direction of the first flipping station is perpendicular to the extension direction of the second flipping station. The first flipping station is located above the second flipping station, and the first plate 121 and the second plate 122 rotate between the first detection station, the second detection station, the first flipping station, and the second flipping station. Further, a rotary drive member 125 is also included to drive the rotating flipping plate 12 to rotate.

[0051] It should be noted that the rotating flipping plate 12 has a first forward rotation state. In the first forward rotation state, the first plate 121 rotates from the first detection station to the first flipping station, that is, rotates 90° forward, so as to change the bag-shaped material 400 on the first plate 121 from a horizontal state to a vertical state. The second plate 122 rotates from the first flipping station to the second flipping station. The connecting component 13 on the first plate 121 is not connected to the bag-shaped material 400, so that the bag-shaped material 400 flips from the first flipping station to the second flipping station under its own weight, that is, falls onto the second plate 122. The connecting component 13 on the second plate 122 is connected to the bag-shaped material 400. At this time, the flipping of the bag-shaped material 400 is completed, and the second detection component 16 can detect the other side of the bag-shaped material 400.

[0052] Furthermore, the first and second inspection stations are located on opposite sides of the conveyor belt. That is, the first inspection component 15 and the second inspection component 16 are arranged on opposite sides in the height direction of the conveyor belt, further reducing the footprint of the vision inspection module 100. In other embodiments, the first and second inspection stations may also be arranged in the length direction of the conveyor belt.

[0053] It should be noted that the rotating flip plate 12 also has a second forward rotation state. In the second forward rotation state, the first plate 121 rotates from the first flip station to the second flip station, and the second plate 122 rotates from the second flip station to the second detection station, that is, it rotates 180° forward. This is so that the second detection component 16 can detect the other side of the bag-shaped material 400.

[0054] In one embodiment, the rotating flipping plate 12 has a first reverse rotation state. In the first reverse rotation state, the first plate 121 rotates past the second flipping station and arrives at the first flipping station, while the second plate 122 rotates from the second detection station to the second flipping station, i.e., rotates 180° in the opposite direction. The rotating flipping plate 12 is also provided with a pusher 14, which pushes the bag-shaped material 400 from the second flipping station to the feeding station, so that the bag-shaped material 400 enters the rejection module 200. In other embodiments, the pusher 14 may not be provided, and the detection conveying assembly 21111 includes a pushing device located on the side of the conveyor belt to push the bag-shaped material 400 to the feeding station.

[0055] In one embodiment, the rotating flip plate 12 further includes a third plate 123 and a fourth plate 124. The third plate 123 is disposed opposite to the first plate 121, and the fourth plate 124 is disposed opposite to the second plate 122. The ends of the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 are connected, and a connecting assembly 13 is disposed on opposite sides of the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124. At this time, the rotating flip plate 12 is arranged in a cross shape. That is, after the pusher 14 pushes away the bag-shaped material 400 on the second plate 122, the conveyor belt can transport the new bag-shaped material 400 to the fourth plate 124 located at the first inspection station.

[0056] Therefore, the rotating flip plate 12 has a new first forward state, a second forward state, and a first reverse state, so that the original fourth plate 124 becomes the new first plate 121, the original first plate 121 becomes the new second plate 122, the original second plate 122 becomes the new third plate 123, and the original third plate 123 becomes the new fourth plate 124. This allows the bagged material 400 on the new first plate 121 to be sequentially inspected, flipped, and inspected before being sent to the rejection module 200. Based on the above process, the rotating flip plate 12, which is arranged in a cross shape, continuously inspects multiple bagged materials 400 conveyed by the conveyor belt.

[0057] Of course, in other embodiments, the third plate 123 and the fourth plate 124 may not be provided, that is, the rotating flip plate 12 is arranged in an L-shape. In this case, the rotating flip plate 12 also has a second reverse rotation state. In the second reverse rotation state, the first plate 121 rotates from the first flip station to the first detection station, and the second plate 122 rotates from the second flip station to the first flip station, that is, it rotates 90° in the opposite direction. At this time, the first plate 121 is located at the first detection station so as to be able to receive the bag-shaped material 400 falling into the first detection station, so that the first detection component 15 can detect the bag-shaped material 400.

[0058] In one embodiment, the pusher 14 includes an air nozzle 141 and an air jet assembly connected to the air nozzle 141. Air nozzles 141 are provided on the side of the first plate 121, second plate 122, third plate 123, and fourth plate 124 near the rotation axis. The airflow ejected from the air nozzle 141 conveys the bagged material 400 that has completed inspection at the second flipping station to the feeding station. In other embodiments, the pusher 14 may also include a push plate and a telescopic drive component for driving the push plate.

[0059] In one embodiment, the connecting assembly 13 includes a negative pressure suction hole 131 disposed on the rotating flip plate 12, and a negative pressure assembly connected to the negative pressure suction hole 131. Atmospheric pressure is used to fix the bag-shaped material 400 to the rotating flip plate 12. In other embodiments, the connecting assembly 13 may include grippers.

[0060] In one embodiment, both the first detection component 15 and the second detection component 16 include a detection housing 151, a light source disposed in the detection housing 151, and a detection camera 153. Both the light source and the detection camera 153 are oriented towards the conveyor belt. The detection housing 151 has an avoidance opening 152 to avoid the rotating flip plate 12. When the first plate 121 is located at the first detection station, the second plate 122 and the detection housing 151 enclose a detection space. When the second plate 122 is located at the second detection station, the first plate 121 and the detection housing 151 enclose a detection space. The detection space can prevent external ambient light from interfering with the detection accuracy of the detection camera 153 in detecting the bagged material 400.

[0061] It should be noted that the inspection camera 153 is a CCD high-definition camera, and the light source can be one of ultraviolet, green, or white light, or multiple light sources can be switched. Through real-time inspection of products using the camera and light source, it can detect heat-generating biological foreign objects (hair, insects), material defects (black spots, ink residue), and printing character defects (missing prints, misalignment), and can identify minute defects as small as 0.1mm.

[0062] In one embodiment, the rejection module 200 includes a flap 21, a drive unit for moving the flap 21, and a waste bin 22 below the flap 21. The flap 21 is located near the feeding station, and a conveying assembly 211 is provided on the upper side of the flap 21 to convey the bagged material 400 along the conveying direction of the conveyor belt. The flap 21 has a rejection position and a transport position. In the rejection position, the flap 21 is away from the conveyor belt, and there is a material passage 221 between the flap 21 and the conveyor belt that connects to the waste bin 22. In the transport position, the flap 21 is close to the conveyor belt, and the bagged material 400 is conveyed by the conveying assembly 211.

[0063] In actual operation, the bag-shaped material 400 enters the first inspection station via the conveyor line 300, where the first inspection component 15 inspects one side of the bag-shaped material 400. Subsequently, the first plate 121 of the rotating flipping plate 12 connects the bag-shaped material 400 via the connecting component 13 and rotates to the first flipping station. At the first flipping station, the connecting component 13 on the first plate 121 releases the bag-shaped material 400, causing it to fall into the second flipping station and be connected by the connecting component 13 of the second plate 122. The second plate 122 continues to rotate, conveying the bag-shaped material 400 to the second inspection station, where the second inspection component 16 inspects the other side of the bag-shaped material 400. After inspection, the rotating flipping plate 12 pushes the bag-shaped material 400 to the feeding station via the pusher 14. At the feeding station, the rejection module 200 determines whether to reject the bag-shaped material 400 based on the visual inspection results. If the product is found to be defective, the flap 21 moves to the rejection position, and the bagged material 400 falls into the waste bin 22 through the feed port 221; if the product is found to be good, the flap 21 remains in the transport position, and the conveying assembly 211 continues to transport the bagged material 400.

[0064] This device achieves the flipping and conveying of the bagged material 400 through the rotating flipping plate 12, enabling the first detection component 15 and the second detection component 16 to perform comprehensive detection on both sides of the bagged material 400, thus improving the accuracy and efficiency of detection. Simultaneously, the rejection module 200 enables the automatic rejection of defective products, reducing manual intervention and improving production efficiency.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
