Description

Technical Field

[0001] The utility model relates to the technical field of bottle body defect detection, in particular to a bottle neck crack centering detection machine. Background Art

[0002] During the manufacturing process of glass bottles, defects may occur in different parts of the bottle body due to molds, temperature, and other factors. Among them, neck defects such as deep cracks in the neck, cracked edges of the neck, and raised neck seams are common problems. The applicant previously applied for a patent document with application number CN201720728586.2, which discloses a visual detection system for neck crack defects in glass container manufacturing. By collecting images of the neck of the glass container, the system can see the characteristics of the neck in 360 degrees without blind spots. However, in the actual production process, the specifications and heights of glass bottles vary. The patent cannot adjust the height in time to accommodate glass bottles of different specifications, and it is difficult to ensure that the bottles on the production line can accurately enter the center position of the detection camera light source, which affects the accuracy of the detection. Utility Model Content

[0003] In order to solve the technical problems in the above-mentioned background technology that the detection camera cannot adjust the height and it is difficult to ensure that the bottles on the production line can accurately enter the center position of the detection camera light source, the utility model provides a bottleneck crack alignment detection machine.

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

[0005] A neck crack centering detection machine comprises a conveyor belt, a centering module positioned in front and behind of the conveyor belt, and a neck crack detector. The centering module comprises two sets of centering units positioned opposite each other on either side of the conveyor belt. Each centering unit comprises a mounting frame, the upper portion of which, on the side closest to the conveyor belt, is equipped with a plurality of centering rollers arranged along the conveyor belt's conveying direction. The outer rings of the plurality of centering rollers are provided with centering belts. The neck crack detector comprises a bracket mounted on one side of the conveyor belt, the neck crack detector unit being mounted on the side closest to the conveyor belt and capable of being raised and lowered.

[0006] The space above the conveyor belt, enclosed by centering belts on either side, forms a passage for bottles to be inspected. The spacing between the two centering belts is slightly larger than the diameter of the bottle to be inspected. When a bottle on the conveyor belt passes through the centering unit, it first contacts the centering belt on at least one side of the conveyor belt and, under the pressure of the centering belt, moves toward the center of the conveyor belt, ensuring that the bottle to be inspected is centered on the conveyor belt, thereby ensuring the accuracy of subsequent inspection processes. The vertical height of the bottleneck inspection unit can be adjusted by raising and lowering it to accommodate various glass bottle sizes.

[0007] In order to ensure that the bottles to be inspected can maintain their original moving speed when passing through the centering belt, and avoid the accumulation of bottles due to the slowdown in the moving speed of the bottles to be inspected, the centering unit also includes a centering motor connected to the centering belt transmission, which is configured to drive the centering belt and the conveyor belt to rotate at the same speed.

[0008] As a preferred embodiment, the distance between the two sets of centering belts is adjustable. When the specifications of the bottles to be inspected are not uniform, the requirements of bottles of different sizes can be met by adjusting the distance between the two sets of centering belts.

[0009] Further preferably, the mounting frame includes a fixed frame and a sliding frame on its upper side capable of sliding perpendicular to the conveying direction of the conveyor belt, with the centering roller located on the side of the sliding frame closest to the conveyor belt. The centering module also includes a drive unit configured to drive the two sets of sliding frames to synchronously slide toward or away from each other. The arrangement of the sliding frames ensures the stability of the centering belt during movement, while the drive unit drives the sliding frames to synchronously slide, ensuring the centering effect of the centering unit and facilitating the adjustment of the spacing of the centering belts at any time, eliminating repeated adjustment steps.

[0010] The specific structure of the sliding frame consists of a first connecting plate slidably connected to the top of the fixed frame. A plurality of fixing rods are vertically mounted on the first connecting plate. A second connecting plate, parallel to the first connecting plate, is mounted at the upper end of each fixing rod. The second connecting plate is positioned above the plane of the conveyor belt. The centering roller is located on the side of the second connecting plate closest to the conveyor belt. The second connecting plate ensures the stability of the centering roller and the centering belt, improving their integrity. Furthermore, a plurality of fixing rods are provided along the circumference of the first connecting plate, further strengthening the overall structural stability.

[0011] In a preferred embodiment, the centering unit further includes a tensioning pulley positioned in front of the centering roller. The centering belt is mounted on the outer ring of the tensioning pulley, and the spacing between the two tensioning pulleys is greater than the spacing between the two sets of centering rollers. The tensioning pulley not only adjusts the path and tension of the centering belt, reducing vibration and noise, but also serves to guide the bottles being inspected, facilitating contact between the bottles and the centering belt.

[0012] Furthermore, the neck crack detector also includes a detection device located in front of the bottleneck detection unit and capable of detecting the height of bottles on the conveyor belt. The detection device can detect whether the height of the bottle to be inspected is consistent with the height of the bottleneck detection unit. If the bottle to be inspected is too high, the conveyor belt needs to be stopped to prevent the bottle from colliding with the bottleneck detection unit.

[0013] Specifically, the detection device includes a photoelectric sensor that rises and falls synchronously with the bottleneck detection unit. The sensor is located above the centering belt. If a bottle on the conveyor belt is at a height inconsistent with the bottleneck detection unit, the photoelectric sensor above the centering belt will detect the presence of the overly tall bottle as it passes the centering unit, and the conveyor belt can be stopped manually or automatically to prevent the overly tall bottle from colliding with the bottleneck detection unit behind the centering belt.

[0014] Through the above design, the beneficial effect of the present invention is: by arranging the centering belts on both sides of the conveyor belt, the bottles to be inspected on the conveyor belt can be moved to the middle of the conveyor belt, ensuring that the bottles to be inspected can accurately enter the detection position of the bottleneck detection unit. At the same time, the centering belt can slide perpendicular to the conveying direction of the conveyor belt, and the bottleneck detection unit with adjustable vertical height ensures that the present invention can adapt to bottles of different sizes.

[0021] Example

[0022] Combine Figures 1 to 3 This embodiment provides a bottleneck crack centering detection machine, including a conveyor belt and a centering module 1 and a neck crack detector 2 arranged in front and behind along the conveying direction of the conveyor belt.

[0023] In this embodiment, the centering module 1 includes two groups of centering units 11 arranged on both sides of the conveyor belt. The centering unit 11 includes a mounting frame 111, and a plurality of centering rollers 112 are arranged along the conveying direction of the conveyor belt on the upper side close to the conveyor belt. The outer rings of the plurality of centering rollers 112 are provided with centering belts 113.

[0024] In order to ensure that the bottles to be inspected can maintain their original moving speed when passing through the centering belt 113 and avoid the accumulation of bottles due to the slowdown in the moving speed of the bottles to be inspected, the centering unit 11 also includes a centering motor that is transmission-connected to the centering belt 113, which is configured to drive the centering belt 113 to rotate at the same speed as the conveyor belt.

[0025] As a preferred embodiment, the distance between the two sets of centering belts 113 is adjustable. When the specifications of the bottles to be inspected are not uniform, the requirements of bottles of different sizes can be met by adjusting the distance between the two sets of centering belts 113 .

[0026] Further preferably, the mounting frame 111 includes a fixed frame 1111 and a sliding frame 1112 on its upper side which can slide perpendicular to the conveying direction of the conveyor belt. The centering roller 112 is arranged on the side of the sliding frame 1112 close to the conveyor belt. The setting of the sliding frame 1112 can ensure the stability of the centering belt 113 during the movement.

[0027] In a specific implementation, the mounting frame 111 is further provided with a track perpendicular to the conveying direction of the conveyor belt, and a slider capable of sliding with the track is provided under the sliding frame 1112. The track is provided to provide support and guidance when the sliding frame 1112 slides.

[0028] Regarding the specific structure of the sliding frame 1112, it comprises a first connecting plate slidably connected to the top of the fixed frame 1111. A plurality of fixing rods are vertically mounted on the first connecting plate. A second connecting plate, parallel to the first connecting plate, is mounted at the upper end of each fixing rod. The second connecting plate is positioned above the plane of the conveyor belt. The centering roller 112 is positioned on the side of the second connecting plate closest to the conveyor belt. The provision of the second connecting plate ensures the stability of the centering roller 112 and the centering belt 113, improving their integrity. Furthermore, a plurality of fixing rods are provided along the circumference of the first connecting plate, further enhancing the robustness of the overall structure.

[0029] Reference Figure 3 The centering module 1 further includes a drive unit 12 configured to drive two sets of sliding frames 1112 to synchronously slide toward or away from each other. The drive unit 12 drives the sliding frames 1112 to synchronously slide, thereby ensuring the centering effect of the centering unit 11 and facilitating the adjustment of the spacing of the centering belts 113 at any time, eliminating the need for repeated adjustment steps.

[0030] In a specific embodiment, the fixed frame 1111 includes a horizontally disposed fixed plate. The drive unit 12 includes at least two drive gears 121 and a transmission belt 122 disposed around the outer rings of the two drive gears 121. The two drive gears 121 are disposed below the two fixed plates, away from the conveyor belt, and are rotatably connected to the fixed plates. The drive unit 12 also includes a drive motor 123 capable of driving the drive gears 121.

[0031] The fixed plate is provided with a through hole perpendicular to the conveying direction of the conveyor belt, and a linkage part 1113 is provided under the first connecting plate. The two sets of linkage parts 1113 are respectively fixed on different sections of the transmission belt 122 between the two driving gears 121, and the two sets of linkage parts 1113 are configured to be able to move synchronously in the opposite direction when the transmission belt 122 rotates.

[0032] As a preferred embodiment, the centering unit 11 further includes a tensioning pulley 114 disposed in front of the centering roller 112. The centering belt 113 is sleeved on the outer ring of the tensioning pulley 114. The spacing between the two tensioning pulleys 114 is greater than the spacing between the two sets of centering rollers 112. The provision of the tensioning pulley 114 can adjust the path and tension of the centering belt 113, reducing vibration and noise. Furthermore, the larger spacing between the two sets of tensioning pulleys 114 can guide the bottles to be inspected, facilitating contact between the bottles to be inspected and the centering belt 113.

[0033] Preferably, the centering motor and the driving motor 123 are both fixedly mounted on the mounting frame 111, and the overall structure is compact and highly stable.

[0034] In this embodiment, the neck crack detector 2 includes a bracket 21 provided on one side of the conveyor belt, and a bottleneck detection unit 22 is provided on a side close to the conveyor belt in a liftable manner.

[0035] As a preferred embodiment, a vertical slide rail 211 is provided on a side of the bracket 21 close to the conveyor belt, and the bottleneck detection unit 22 is connected to the slide rail 211 by sliding up and down via a lifting frame 212 .

[0036] Furthermore, the neck crack detector 2 also includes a detection device located in front of the bottleneck detection unit 22 and capable of detecting the height of the bottles on the conveyor belt. The detection device can detect whether the height of the bottle to be inspected is consistent with the height of the bottleneck detection unit 22. If the bottle to be inspected is too high, the conveyor belt needs to be stopped to prevent the bottle to be inspected from colliding with the bottleneck detection unit 22.

[0037] Specifically, the detection device includes a photoelectric sensor that can be raised and lowered synchronously with the bottleneck detection unit 22. A connecting rod parallel to the conveyor belt's direction is provided on the side of the lifting frame 212 facing the centering belt 113. The photoelectric sensor is located at the end of the connecting rod facing away from the lifting frame 212 and positioned above the centering belt 113. If a bottle appears on the conveyor belt that is not at the same height as the bottleneck detection unit 22, the photoelectric sensor above the centering belt 113 will promptly detect the presence of the overly high bottle as the bottle passes the centering unit 11, and the conveyor belt can be stopped manually or automatically to prevent the overly high bottle from colliding with the bottleneck detection unit 22 behind the centering belt 113.

[0038] The utility model uses the centering belts 113 arranged on both sides of the conveyor belt to move the bottles to be inspected on the conveyor belt to the middle of the conveyor belt, ensuring that the bottles to be inspected can accurately enter the detection position of the bottleneck detection unit 22. At the same time, the centering belts 113 can slide perpendicular to the conveying direction of the conveyor belt, and the bottleneck detection unit 22 with adjustable vertical height ensures that the utility model can adapt to bottles of different sizes.
