Description

Technical Field This invention relates to the field of glass bottle production and inspection, and in particular to an automatic alignment glass bottle conveying and inspection system. Background Technology Glass bottles are commonly used containers for cosmetics. Currently, most glass bottles are manufactured using in-mold blow molding. This method is prone to defects such as air bubbles, impurities, and cracks. While some production lines use image acquisition devices to inspect glass bottles, the inconsistent positions and angles of the bottles make it impossible to capture a single image, especially for irregularly shaped or flat bottles. Therefore, minimizing the interference from inconsistent bottle positions and angles is crucial for effective glass bottle inspection.

[0001] For example, a high-center-of-gravity flat bottle (202130010815.9) manufactured by the applicant is prone to tipping over when transported to the conveyor belt, and is also prone to deflection when placed and displacement when corrected, which increases the difficulty of subsequent video inspection.

[0002] The applicant's prior patent 202023347167.5 discloses a front-mounted bottle straightening device that corrects the position of a glass bottle by using two vertical belts spaced apart. Although this method can solve the problem of glass bottle deflection to a certain extent, it is easy for bottles with a high center of gravity to tip over. Summary of the Invention This invention provides an automatic alignment glass bottle conveying and inspection system that can accurately inspect glass bottles from multiple angles and directions, effectively solving the problems existing in the prior art.

[0005] Furthermore, the bottle-discharging station is formed at the end of the first conveyor belt.

[0006] Furthermore, the guide shell includes a guide portion having the inner cavity, the guide portion having a bottle-blocking portion extending to the upper side of the first conveyor belt and a limiting portion extending to both sides of the top of the first conveyor belt, wherein the height of the bottle-blocking portion and the top surface of the first conveyor belt is less than the height of the glass bottle, and the distance between the two limiting portions is less than the height of the glass bottle.

Detailed Implementation To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0014] The embodiments of the present invention are as follows Figure 1-4As shown, an automatic alignment glass bottle conveying and detection system includes: a first conveyor belt 1 for conveying glass bottles, the first conveyor belt 1 having a bottle discharge station 101; a bottle dropping mechanism, disposed at the bottle discharge station 101 of the first conveyor belt, including a guide shell 2 with an inner cavity, the cross-section of the guide shell 2 gradually decreasing from top to bottom, and the inner cavity forming a directional section 201 at the bottom of the guide shell 2, the directional section 201 being able to position and abut against the surface of the glass bottle, the guide shell 2 having a guide groove 6 penetrating along a first direction, and the guide shell 2 having an openable and closable opening 15 on the penetrating side of the guide groove 6; a first detection mechanism including a downwardly positioned first CCD module 3, the first CCD module 3 being disposed at the top of the guide shell 2, so that when the glass bottle moves to position and abut against the directional section 201, the first CCD module 3... The system is capable of detecting the image of the mouth of the glass bottle; a second detection structure includes a second CCD module 4, which is disposed on the outside of the guide shell 2, so that the second CCD module 4 forms a lateral detection area 5 on the outside of the guide shell 2, and the second CCD module 4 can take pictures and detect the side of the glass bottle; a second conveyor belt 19 is disposed on the lower side of the guide shell 2, and the second conveyor belt 19 passes under the lateral detection area 5; a second moving component includes a first telescopic part 7 that is movable along the extension direction of the guide groove 6, a second telescopic part 8 disposed on the first telescopic part, and a bottle body fixing member 9 disposed at the end of the second telescopic part 8, the bottle body fixing member 9 can fix the glass bottle in the guide shell 2, so that the first telescopic part 7 can move to drive the glass bottle from the opening 15 to the second conveyor belt 19.

[0015] When the online device of the present invention is in use, the glass bottle moves on the conveyor belt to the bottle dispensing station 101 and enters the guide shell 2, allowing the glass bottle to slide to the orientation section 201 and be positioned and abutted. At this time, the first CCD module 3 performs image detection on the mouth of the glass bottle. Then, the second moving component moves the bottle body fixing member 9 to the guide groove 6, and the second telescopic part 8 moves the bottle body fixing member 9 to the glass bottle and fixes the glass bottle. At this time, the opening 15 opens, and the glass plate is moved to the second conveyor belt 19 by the first telescopic part 7 and released on the second conveyor belt 19. When the second conveyor belt 19 moves the glass bottle to the side detection area 5, the second CCD module 4 takes a picture of the side of the glass bottle for detection.

[0016] The technical advantages of this application are as follows: by positioning the glass bottle using the guide shell 2, the first CCD module 3 can accurately detect the image of the bottle opening. Furthermore, the position of the glass bottle can be determined so that the bottle body fixing component 9 can be moved and fixed in the designated position. By clamping the moving glass bottle with the second moving component, after the orientation section 201 determines the bottle's orientation (especially for flat bottles), the bottle's position is stable and its angle is uniform when moving to the second conveyor belt 19, facilitating detection by the second CCD. Simultaneously, the cooperation between the guide shell 2 and the bottle body fixing component 9 also prevents high-center-of-gravity glass bottles from tipping over. Especially when a glass bottle tipps over on the conveyor belt, detection can still be completed even for bottles with their openings facing upwards.

[0017] In the illustrated embodiment, the second moving component is further specifically configured as follows: two second telescopic parts 8 are provided, each located on one side of the guide shell 2; the bottle body fixing component 9 includes a claw. As shown in the figure, the first telescopic part 7 includes a U-shaped rod and a first telescopic rod that drives the U-shaped rod to extend and retract. The second telescopic part 8 is a second telescopic rod located inside the U-shaped rod. The claw is an arc-shaped claw that abuts against the side of the bottle body. Thus, when it is necessary to fix the glass bottle, the first telescopic rod moves, causing the claw to move to the side of the glass bottle. The extension and retraction of the second telescopic rod drives the claw to move and clamp the glass bottle. The first telescopic rod moves the glass bottle to the second conveyor belt 19, and at the same time, the first telescopic rod provides the glass bottle with the same speed as the second conveyor belt 19, so that after the claw releases the glass bottle on the upper side of the second conveyor belt 19, the glass bottle can be stably placed on the second conveyor belt 19.

[0018] for Figure 1 In the illustrated embodiment, more specifically, the bottle-discharging station 101 is formed at the end of the first conveyor belt 1. Figure 1 As shown, by setting a bottle-discharging station 101 at the end of the first conveyor belt 1, the glass bottles can be automatically moved to the guide shell 2 on the first conveyor belt 1.

[0019] In an alternative embodiment, the bottle-discharging station can also be located on the side of the conveyor belt, where a cylinder pusher is installed on the side of the conveyor belt to push the glass bottles onto the guide shell 2.

[0020] Regarding the setting of guide shell 2, in Figure 1 In the illustrated embodiment, more specifically, the guide shell 2 includes a guide portion having the inner cavity, the guide portion having a bottle-blocking portion 11 extending to the upper side of the first conveyor belt 1 and limiting portions 12 extending to both sides of the top of the first conveyor belt 1, wherein the height of the bottle-blocking portion 11 and the top surface of the first conveyor belt 1 is less than the height of the glass bottle, and the distance between the two limiting portions 12 is less than the height of the glass bottle.

[0021] like Figure 2 As shown, by setting the bottle-blocking part 11, when the first conveyor belt 1 moves the glass bottle, the bottle-blocking part 11 can automatically push the glass bottle, so that the mouth of the glass bottle faces away from the guide shell 2. Thus, when the first conveyor belt 1 moves the glass bottle into the guide shell 2, it ensures that the mouth of the pushed glass bottle is facing upward, so that the fixing part can enter the bottle mouth.

[0022] The limiting parts 12 on both sides can guide the glass bottle to move towards the opening of the guide shell 2 after it is tilted, preventing the glass bottle from moving out of the first conveyor belt 1.

[0023] for Figure 1 In the illustrated embodiment, a further optimization is that the guide shell 2 includes an upper shell 13 and a lower shell 14. The lower shell 14 is provided with the directional section 201, and the upper shell 13 is provided with a vibrator. The lower shell 14 and the upper shell 13 are separate structures. By providing a vibrator, the glass bottle can be prevented from getting stuck in the upper shell 13 when it moves downward, ensuring that the glass bottle falls normally. By making the upper shell 13 and the lower shell 14 separate structures, the vibration transmitted from the upper shell 13 to the glass bottle can be reduced after the glass bottle is positioned in the lower shell 14, thereby enabling the first CCD module 33 to monitor stably. The vibrator can be an existing vibrator, and the vibrator is preferably installed on the side of the upper shell 13 closer to the first conveyor belt 1.

[0024] In the illustrated embodiment, the gap between the upper housing 13 and the lower housing 14 forms a guide groove 6.

[0025] For the installation of the vibrator, it is preferable to use an existing vibration motor, which can be directly installed on the upper housing 13.

[0026] A further optimization of the present invention is that the moving direction of the second conveyor belt 19 is perpendicular to the moving direction of the first conveyor belt 1. As shown in the figure, when the glass bottle is a flat bottle, the narrow side of the glass bottle faces the moving direction of the second conveyor belt 19 to facilitate the glass bottle entering and exiting the opening 15. Also, when the glass bottle is placed on the second conveyor belt 19, the wide side of the glass bottle faces the side of the second conveyor belt 19, which is beneficial for the second CCD module 4 to take pictures and detect the glass bottle.

[0027] Regarding the configuration of the positioning unit, Figure 1 In the illustrated embodiment, more specifically, the guide shell 2 is provided with an elastic rubber plate 16 at the position of the opening 15, such as... Figure 4As shown, by providing an elastic rubber plate 16 at the opening 15 position in the guide shell 2, when the glass bottle is removed from the guide shell 2, the glass bottle is pushed outward by the elastic rubber plate 16 at the opening 15 position, thus passing through the opening 15. This ultimately causes the glass bottle to leave the guide shell 2. After the glass bottle leaves the elastic rubber plate 16, the elastic rubber plate 16 returns to its original position, waiting for the next glass bottle to fall.

[0028] Preferably, the guide shell 2 includes a rigid shell portion, the shell portion having through holes for mounting elastic rubber plates 16, and an opening 15 formed between the two elastic rubber plates 16. In an alternative embodiment, the guide shell 2 can also be configured as a single elastic rubber guide shell 2, with the elastic rubber plates 16 directly formed on both sides of the opening 15.

[0029] Alternatively, in an alternative embodiment, the positioning part can be configured as described below, wherein the guide shell 2 is hinged to a positioning plate at the opening 15, and a reset elastic element is provided between the positioning plate and the guide shell 2, the reset elastic element driving the positioning plate to rotate toward the directional section 201. Specifically, the reset elastic element can be a torsion spring or a spring.

[0030] for Figure 1 In the illustrated embodiment, more specifically, the bottom of the guide shell 2 is provided with an openable and closable lower baffle 1718, and the detection system further includes a third CCD module 10 disposed below the lower baffle 17. By providing the lower baffle 17, after the glass bottle is gripped by the jaws, the lower baffle 17 can be moved away, and the third CCD module 10 can take a picture of the bottom of the bottle for detection. Specifically, the lower baffle 17 can be moved by a bottom cylinder. The second moving component and the bottom cylinder are simultaneously connected to a processor, so that after the second moving component clamps and fixes the glass bottle, the processor issues a command to the bottom cylinder to extend or retract.

[0031] In the illustrated embodiment, more specifically, the guide shell 2 has an openable and closable bottle discharge port 18 on the side opposite to the opening 15. This allows the second moving component to move the bottle through the discharge port 18 and discharge it when the glass bottle is inverted or when the first CCD module 3 or the second CCD module 4 detects a defect in the glass bottle. The opening and closing mechanism of the discharge port 18 can refer to the configuration of the opening 15.

[0032] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0033] Any aspects of this invention not described in detail are well-known to those skilled in the art.
