Detailed Implementation

[0024] like Figure 1 As shown, this embodiment of the invention provides a bottle cap suspension transport assembly for use in detecting the inner side of bottle caps. This bottle cap suspension transport assembly is mounted on a detection platform.

[0025] The bottle cap suspension transport assembly includes two conveyor units 1 and a suspension frame 2. The two conveyor units 1 are used to clamp and transport bottle caps. The suspension frame 2 is mounted on the inspection platform and spans across the two conveyor units 1 above and to the left and right sides, with the two conveyor units 1 mounted on the suspension frame 2.

[0026] Two conveyor units 1 are suspended above the inspection platform by a suspension frame 2. This allows the bottle caps to be positioned above the inspection platform and suspended below it as they are conveyed between the two conveyor units 1, so that image acquisition mechanisms such as cameras and light sources can be installed below the bottle caps to capture images of the inside of the bottle caps. In addition, a support-type cap-shifting unit is installed downstream of the conveying route of the two conveyor units 1. The support-type cap-shifting unit is aligned between the two conveyor units 1, positioned below them, and one end extends below the output end of the two conveyor units 1, with its top surface aligned with the bottom of the bottle cap.

[0027] By suspending the bottle caps during transport and using an image acquisition method from below, the bottle caps can be transported in an upright position when inspecting the inner image. After the inner image is acquired, the bottle caps can be directly placed on the support-type cap transfer unit without the need for flipping. This allows for smooth connection between the two inspection processes of the bottle caps, improving the overall transport and inspection efficiency of the bottle caps.

[0028] Compared to bottle body inspection, bottle cap inspection is different because the height of the bottle cap is smaller than that of the bottle body and the diameter is also smaller. Therefore, the inventors designed the suspended conveying device of this application specifically for the characteristics of bottle cap inspection. The horizontal suspended frame 2 (detailed structure will be described later) suspends the two conveyor units 1 between the suspended frame 2, which can avoid occupying the space under the conveyor units 1 and provide sufficient installation space for the installation of image acquisition mechanisms such as cameras and light sources.

[0029] In detail, such as Figure 2 and Figure 3 As shown, both conveyor units 1 extend forward and backward, are parallel to each other, and are horizontally symmetrical. Specifically, each conveyor unit 1 includes a mounting plate 11 that extends forward and backward. A drive wheel 12 and a driven wheel 13 are provided on the underside of the mounting plate 11, along with a conveyor belt 14 fitted onto the drive wheel 12 and the driven wheel 13. The drive wheel 12 and the driven wheel 13 are located at the front and rear ends of the mounting plate 11, and their axes of rotation are vertical. A distance is provided between the two conveyor belts 14 of the two conveyor units 1. The opposing belt portions of the two conveyor belts 14 cooperate with each other, clamping the sides of the bottle cap and conveying the bottle cap between the two conveyor belts 14.

[0030] The mounting plate 11 specifically includes a fixing part 111 and wheel frames 112 connected to both ends of the fixing part 111. The driving wheel 12 and the driven wheel 13 are rotatably connected to the two wheel frames 112 respectively. Both the fixing part 111 and the wheel frames 112 are plate-shaped.

[0031] A drive motor 15 is mounted on the upper side of the wheel frame 112 connecting to the drive wheel 12, and is directly or via a transmission connection to the drive wheel 12. The drive motors 15 of the two conveyor units 1 are located at the same end.

[0032] A slotted hole 1121 is provided on the wheel frame 112 connecting the driven wheel 13, extending vertically through the wheel frame 112. The slotted hole 1121 is a straight hole extending front to back, allowing the mounting shaft of the driven wheel 13 to slide and be fixed within the slotted hole 1121. An adjusting screw 1122 is provided on the end face of the wheel frame 112 at a position corresponding to the slotted hole 1121. The adjusting screw 1122 extends front to back, inserts into the slotted hole 1121, and is inserted into the mounting shaft of the driven wheel 13. The mounting shaft has a threaded hole that mates with the adjusting screw 1122. Tightening the adjusting screw 1122 allows the driven wheel 13 to move forward or backward, thereby increasing or decreasing the distance between the driven wheel 13 and the driving wheel 12. This not only facilitates the installation of the conveyor belt 14 onto the driving wheel 12 and the driven wheel 13 but also allows for adjustment of the tension of the conveyor belt 14.

[0033] A base 16 is provided on the upper side of the fixing part 111 of the mounting plate 11, and the two conveyor units 1 are suspended and hoisted by the suspension frame 2 connected to the base 16. The base 16 is located close to the drive wheel 12 to cope with the weight of the drive motor 15, so that the weight at both ends of the base 16 can be more balanced when the conveyor unit 1 is hoisted.

[0034] In addition, in order to improve the clamping tightness of bottle caps when conveying them, multiple side wheels 17 are provided on the lower side of the mounting part of the mounting plate 11. The multiple side wheels 17 are located inside the conveyor belt 14 and are distributed on the left and right sides of the vertical plane where the shafts of the drive wheel 12 and the driven wheel 13 are located. The wheel surfaces of the side wheels 17 are all in contact with the inner side of the conveyor belt 14. The multiple side wheels 17 located on the same side of the mounting plate 11 are evenly spaced back and forth to support the belt body of the conveyor belt 14 between the drive wheel 12 and the driven wheel 13 and improve the tension.

[0035] The two wheel frames 112 are positioned higher than the fixed part 111 to provide space for the rotating components of the driving wheel 12 and the driven wheel 13 (e.g., rolling bearing assembly), so that the conveyor belt 14 is closer to the lower side of the fixed part 111, reducing the torque on the shaft of the side wheel 17, and enabling the side wheel 17 to rotate smoothly for a long time.

[0036] In this embodiment, the number of side wheels 17 on the mounting plate 11 near the bottle cap clamping side is greater than the number of side wheels 17 on the other side. Furthermore, the distance between adjacent side wheels 17 on the mounting plate 11 near the bottle cap clamping side is less than the diameter of the bottle cap. This results in higher belt tension on the conveyor belt 14 clamping the bottle cap, ensuring a tight grip throughout the bottle cap transport process and preventing the bottle cap from falling off due to insufficient clamping caused by the stretchability of the conveyor belt 14 when it reaches the middle position.

[0037] In this embodiment, the conveyor belt 14 is preferably a synchronous belt, and the driving pulley 12, the driven pulley 13 and the side pulley 17 are preferably synchronous belt pulleys.

[0038] The suspended frame 2 specifically includes two end plates 21 located on the left and right sides of the two conveyor units 1. Both end plates 21 extend forward and backward and are mounted on the testing platform via two columns. At least two horizontal shafts 22 extending left and right are connected between the two end plates 21, and the base 16 is connected to the horizontal shafts 22. The at least two horizontal shafts 22 are horizontally distributed forward and backward.

[0039] In this embodiment, the suspended frame 2 is also provided with a bidirectional lead screw 23, which extends to the left and right and passes through the base 16 of the two conveyor units 1. The bidirectional lead screw 23 is parallel to the horizontal axis 22 and is preferably located in the middle of the horizontal axis 22. One or both ends of the bidirectional lead screw 23 are rotatably connected to the end plate 21 on the corresponding side, and preferably, one end passes through the end plate 21 and is provided with a handwheel 24 at the end to rotate the bidirectional lead screw 23. The base 16 of the two conveyor units 1 is provided with a bushing 18 corresponding to the horizontal axis 22. The bushing 18 is sleeved on the horizontal axis 22, and the base 16 is slidably connected to the horizontal axis 22 through the bushing 18. On the base 16 of the two conveyor units 1, corresponding to the positions of the bidirectional lead screw 23, there are capped nuts 19. The two capped nuts 19 have different thread directions. The bidirectional lead screw 23 is machined with threads of different directions from the middle to both ends. The two capped nuts 19 are respectively engaged with the two different thread directions of the bidirectional lead screw 23. When the bidirectional lead screw 23 is rotated, the two capped nuts 19 drive the two bases 16 to move in opposite directions at the same time, thereby adjusting the distance between the two conveyor belts 14 to accommodate bottle caps of different diameters.

[0040] Additionally, a locking handle 25 is threaded onto the end plate 21 through which the bidirectional lead screw 23 passes. The locking handle 25 has a stud, one end of which is connected to the locking handle 25, and the other end is inserted into the end plate 21 and threadedly connected to it. Preferably, the stud is located directly above the bidirectional lead screw 23, and its vertical extension is perpendicular to the bidirectional lead screw 23. The end of the stud inserted into the end plate 21 can abut against the bidirectional lead screw 23 during screwing, pressing it firmly against the cylindrical surface of the bidirectional lead screw 23, thereby locking the bidirectional lead screw 23 and thus locking the distance between the two conveyor belts 14.
