Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a novel foreign object detection device for bottles. Background Technology

[0002] After the production of wine bottles or the bottling of wine is completed, it is usually necessary to inspect the bottles for defects or foreign objects to ensure the quality of the finished product. The commonly used inspection method is to transport the bottles in a straight line using a conveyor and to set up sampling cameras along the transport path to collect images. Based on the collected image information, the inspection work for bottle defects or foreign objects is completed. On the one hand, the straight-line conveying method will occupy a large amount of deployment space. On the other hand, in order to ensure the quality of image acquisition, a preset time interval needs to be paused when the bottle reaches the sampling camera position, which affects the inspection efficiency of the wine bottles. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a novel foreign object detection device for bottles.

[0004] The technical solution of this utility model is as follows:

[0005] A novel foreign object detection device for bottles includes a main board and a wheel conveyor system mounted on it. The wheel conveyor system has a material conveying system on one side that can dock with it to complete the transfer of wine bottles. The main board is also equipped with a detection system located on the outer side of the wheel conveyor system. The wine bottles can be transported circumferentially by the conveyor system, and the detection system can detect foreign objects inside the bottles during the transportation process.

[0006] As the core technical concept of this utility model, the rotary conveyor system includes a turntable and a bottle-fixing mechanism on its outer ring. Through the docking of the fixing mechanism with the conveying system, it can receive or transfer bottles to the conveying system. This circular transport method significantly reduces the space requirements for the conveying system. The detection system includes a bracket located outside the turntable, on which is an arc-shaped slide rail whose center coincides with the turntable axis and can oscillate back and forth around the center. A detection camera mechanism is connected to the slide rail, and the detection camera mechanism is located above the rotation trajectory of the bottle-fixing mechanism. Based on this structure, the movement of the slide rail can drive the detection camera mechanism to rotate with the bottle, and complete the detection of foreign objects inside the bottle during the following process. After the detection is completed, it can return to complete the detection of the next bottle or the next group of bottles. This following detection method significantly improves detection efficiency.

[0007] As described above, in the novel bottle foreign object detection device, regarding the swing setting of the slide rail, the bracket has multiple sets of guide mechanisms arranged in an arc. The guide mechanism includes two rollers with a horizontal gap. The slide rail has grooves on both sides, and the rollers and grooves roll in cooperation, thereby enabling the slide rail to move around the center under the action of multiple sets of guide mechanisms.

[0008] As described above, in a preferred embodiment of the novel bottle foreign object detection device, to ensure the clarity of image acquisition by the detection camera mechanism, the detection system further includes an arc-shaped bottle passage formed by the gap between two arc-shaped light sources. The rotation trajectory of the bottle fixing mechanism coincides vertically with the bottle passage, and the detection camera mechanism is located above the bottle passage. The bottle can pass through the bottle passage under the load of the fixing mechanism.

[0009] As a further preferred embodiment, to ensure the accuracy of the detection results obtained by the detection system, the detection system is provided with multiple sets, and the detection camera mechanism includes sampling cameras, with the multiple sets of sampling cameras having different shooting angles.

[0010] Preferably, in order to enable the detection system to have a longer reset time and reduce its oscillation frequency, all of the detection systems include the same number of sampling cameras.

[0011] As described above, a novel bottle foreign object detection device includes a star wheel mechanism and an input line and an output line on its outer side in terms of the structure of the feeding system. The star wheel mechanism is configured to sequentially feed the bottles on the input line to the bottle fixing mechanism and to feed the bottles on the bottle fixing mechanism to the output line.

[0012] As described above, a novel foreign object detection device for bottles includes a support unit capable of supporting the bottle and a clamping unit capable of clamping the bottle on the support unit, in order to ensure the stability of the bottle during transport with the bottle-fixing mechanism.

[0013] The beneficial effects of this utility model are as follows: This utility model is a novel foreign object detection device for bottles. The bottles can be transported circumferentially with the turntable under the action of the bottle fixing mechanism. This circumferential transportation method significantly reduces the space requirements for the layout of the conveying system. The movement of the slide rail can drive the detection camera mechanism to rotate with the bottles and complete the detection of foreign objects inside the bottles during the following process. After the detection is completed, it can be returned to complete the detection of the next bottle or the next group of bottles. The following detection method significantly improves the detection efficiency. Attached Figure Description

[0025] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0026] Example

[0027] This embodiment provides a novel foreign object detection device for bottles. See [link / reference] Figure 1 and Figure 2The device includes a horizontally arranged main board 1, a wheel conveyor system 2 in the middle of the main board 1, a material conveying system 3 on one side of the wheel conveyor system 2 that can dock with it to complete the transfer of wine bottles, and a detection system 4 on the main board 1 located outside the wheel conveyor system 2. The wine bottles can be transported circumferentially by the conveyor system, and the detection system 4 can detect foreign objects inside the bottles during the transportation process. The structure of the detection device (the above-mentioned novel bottle foreign object detection device) will be described in more detail below with reference to the accompanying drawings.

[0028] In this embodiment, combined with Figure 3 The rotary conveyor system 2 includes a turntable 21 horizontally positioned above the center of the main board 1. The outer circumference of the turntable 21 has several bottle-fixing mechanisms 22, which connect to the conveying system 3 via these fixing mechanisms. This allows the system to receive or transfer bottles to the conveying system 3. This circular transport method significantly reduces the space requirements for the conveying system. It should be noted that... Figure 3 Only three bottle-fixing mechanisms 22 are shown; in reality, the bottle-fixing mechanisms 22 are arranged in a full circle around the outer ring of the turntable 21.

[0029] Regarding the drive structure of the wheel, the main board 1 has a rotating spindle in the middle, the turntable 21 is coaxially mounted on the upper end of the spindle, the lower end of the spindle passes through the main board 1 and has a main gear, and the lower side of the main board 1 is also provided with a rotation drive motor, which meshes and is connected to the main gear. The rotation drive motor can drive the turntable to rotate, and then drive the turntable 21 to rotate through the spindle.

[0030] As a preferred implementation, to ensure the stability of the bottle during transport with the bottle securing mechanism 22, the bottle securing mechanism 22 includes a supporting unit capable of supporting the bottle and a clamping unit capable of clamping the bottle on the supporting unit.

[0031] Combination Figure 4 and Figure 5 Specifically, regarding the structure of the bottle-fixing mechanism 22, the outer circumference of the turntable 21 has several fixing ports. The bottle-fixing mechanism 22 includes a mounting base 221 located within the fixing ports. The supporting unit includes a support rod 222 vertically located within the mounting base 221. The upper end of the support rod 222 extends out of the mounting base 221 and is horizontally provided with a support plate 223, which can support the wine bottle. The upper end of the support rod 222 is provided with a U-shaped groove. The clamping unit includes clamping arms 224 arranged opposite to each other and hinged at one end to the upper end of the U-shaped groove. The non-hinged end of the clamping arm 224 extends to the outside of the support plate 223. A slider 225 is also vertically slidably provided inside the U-shaped groove. Both clamping arms 224 are hinged to the slider 225 via a hinge rod 226. The vertical sliding of the slider 225 can drive the clamping arms 224 to clamp or release the wine bottle on the support plate 223.

[0032] Furthermore, the clamping unit also includes a drive rod 227 vertically inserted inside the support rod 222. The upper end of the drive rod 227 extends into the U-shaped groove and is fixed to the lower side of the slider 225, while the lower end extends out of the support rod 222 and is provided with a drive block 228. A cam guide rail 23 is also provided on the main board 1, located below the turntable 21 and near the material conveying system 3. A spring is provided on the outer ring of the upper end of the drive rod 227, with the upper and lower ends of the spring respectively abutting against the slider 225 and the support rod 222. Based on the above structure, under the action of the spring... The lower part can push the slider 225 upward, and then push the clamping arm 224 to clamp the wine bottle on the tray 223 through the hinge rod 226. When the bottle fixing mechanism 22 rotates with the turntable 21 to the docking position with the material conveying system 3, that is, the position of the cam guide rail 23, under the guidance of the cam guide rail 23, it can push the drive block 228 to move down, and then pull the slider 225 down through the drive rod 227. Finally, the hinge rod 226 pulls the clamping arm 224 to release the wine bottle on the tray 223, ensuring that the bottle fixing mechanism 22 can be smoothly docked with the material conveying system 3.

[0033] As a further preferred embodiment, to ensure that the detection system 4 can complete the detection work more comprehensively, the support rod 222 is rotatably mounted in the mounting base 221, and the lower end of the mounting base 221 extends out and is provided with a pulley 229. The turntable 21 is provided with an adjustment drive motor connected to the pulley 229 via a belt. Through the action of the adjustment drive motor, the support rod 222, the support plate 223, the clamping arm 224, the slider 225, the hinge rod 226 and the drive rod 227 can be rotated as a whole to realize the rotation drive of the wine bottle. On this basis, in order to ensure the effectiveness of the cooperation between the drive block 228 and the cam guide rail 23, the drive rod 227 and the drive block 228 are rotatably connected. The lower side of the turntable 21 is provided with a limiting plate corresponding to the position of the bottle fixing unit. The limiting plate has a vertical strip-shaped sliding opening, and one side of the drive block 228 is set through the sliding opening to prevent the drive block 228 from rotating with the drive rod 227, so as to ensure that it can cooperate smoothly with the cam guide rail 23 and straighten and release the clamping arm 224.

[0034] In this embodiment, combined with Figure 6 The conveying system 3 includes a star wheel mechanism 33 and an input line 31 and an output line 34 on its outer side. The star wheel mechanism 33 is configured to convey the bottles on the input line 31 to the bottle fixing mechanism 22 in sequence, and to convey the bottles on the bottle fixing mechanism 22 to the output line 34.

[0035] Specifically, the star wheel mechanism 33 includes a central guard plate 331 horizontally disposed on the outside of the turntable 21. The central guard plate 331 has arc-shaped notches on opposite sides. The star wheel mechanism 33 also includes a feeding star wheel 332 and a discharging star wheel 333 coaxially rotatably disposed in the two notches. The outer rings of the feeding star wheel 332 and the discharging star wheel 333 are provided with bottle openings, and are rotatably disposed on the main board 1 only through a secondary shaft. The lower end of the secondary shaft extends to the lower side of the main board 1 and is provided with a secondary gear meshing with the main gear. The rotation of the main gear can drive the secondary gear to rotate, thereby driving the feeding star wheel 332 and the discharging star wheel 333 to rotate.

[0036] Based on the above structure, the bottle outlet end of the input line 31 is located near the feeding star wheel 332, and a spiral feeding mechanism 32 is also provided on the outside. The spiral feeding mechanism 32 includes a feeding roller that is horizontally rotated along the conveying direction of the input line 31 and has a spiral groove on its outer ring. When the bottle moves along the input line 31 to the position of the spiral feeding mechanism 32, it can be conveyed to the feeding star wheel 332 under the action of the feeding roller, and the bottle is sequentially conveyed to the bottle fixing mechanism 22 of the conveying system under the action of the feeding star wheel 332. The bottle inlet end of the output line 34 is located near the discharge star wheel 333. When the bottle rotates one revolution with the turntable 21 to the position of the discharge star wheel 333, it can be conveyed to the output line 34 under the action of the discharge star wheel 333.

[0037] In this embodiment, combined with Figure 7 The detection system 4 includes a bracket 41 located outside the turntable 21, on which is an arc-shaped slide rail 42 whose center coincides with the axis of the turntable 21 and can swing back and forth around the center. A detection camera mechanism is connected to the slide rail 42 and is located above the rotation trajectory of the bottle fixing mechanism 22. Based on this structure, the movement of the slide rail 42 can drive the detection camera mechanism to rotate with the bottle and complete the detection of foreign objects inside the bottle during the follow-up process. After the detection is completed, it can return to complete the detection of the next bottle or the next group of bottles. The follow-up detection method significantly improves the detection efficiency.

[0038] Regarding the swing setting of the slide rail 42, the bracket 41 has multiple sets of guide mechanisms arranged in an arc. The guide mechanism includes two rollers with a horizontal gap. The slide rail 42 has grooves on both sides, and the rollers and grooves are in rolling cooperation. The bracket 41 is also equipped with a swing drive 43 that is connected to the slide rail 42 for transmission. Through the action of the swing drive 43, the slide rail 42 is driven to reciprocate around the center under the action of multiple sets of guide mechanisms.

[0039] As a preferred embodiment, to ensure the clarity of image acquisition by the detection camera mechanism, the detection system 4 further includes a light source mechanism 46. The light source mechanism 46 includes an arc-shaped bottle passage formed by the gap between two arc-shaped light sources. The rotation trajectory of the bottle fixing mechanism 22 coincides vertically with the bottle passage. The detection camera mechanism is located above the bottle passage, and the wine bottle can pass through the bottle passage under the load of the fixing mechanism.

[0040] As a further preferred embodiment, in order to ensure the accuracy of the detection results performed by the detection system 4, the detection system 4 is provided with multiple sets, and the detection camera mechanism includes a mounting bracket 44 located on the lower side of the slide rail 42 and a sampling camera 45 located on the lower side of the mounting bracket 44, and the multiple sets of sampling cameras 45 of the detection system 4 have different shooting angles.

[0041] Preferably, in order to enable the detection system 4 to have a longer reset time and reduce its swing frequency, all sets of the detection systems 4 include the same number of sampling cameras 45.
