Bottle caps have the function of keeping the contents of the product sealed, as well as the functions of preventing theft and opening and ensuring security. Therefore, they are widely used in bottled products.

[0003] When bottle caps are pressed onto outer packaging, the process involves pressing, sampling quality inspection, and calculating the pass rate to determine the pass rate of beverage bottle cap pressing. However, using estimation to determine the pass rate not only introduces significant errors but also easily leads to delays in results.

[0011] The press-fit qualification rate monitoring system includes a human-machine interface structure.

[0014] This invention provides a continuous conveying capping device for beverage bottle caps and a capping qualification rate monitoring system thereon, which has the following beneficial effects:

[0015] 1. The continuous conveying capping device for beverage bottle caps and its capping qualification rate monitoring system use a second pressure sensor to detect the downward reaction force on the clamping parts. This sensor detects whether the bottle cap separates from the outer packaging when subjected to an upward force within a certain range. Therefore, the clamping structure can convert the pushing and pulling force controlled by the telescopic hydraulic cylinder to the force used to detect the qualified capping of the outer packaging. This allows for timely detection of the processing qualification rate. When consecutive failures occur, workers can stop the loss in time and reduce the cost of the conveying capping equipment.

[0016] 2. The continuous conveying capping device for beverage bottle caps and its capping qualification rate monitoring system, with the image analysis module electrically connected to the control module, control the clamping structure to perform the third and fourth operations in sequence. This serves to detect whether the bottle cap separates from the outer packaging after local stress and deformation of the outer packaging, whether the beverage inside the outer packaging is sprayed out, and whether the bottle cap separates from the outer packaging when subjected to a certain degree of upward force.

[0017] 3. In this continuous conveying capping device for beverage bottle caps and its capping qualification rate monitoring system, when the counting module, which is electrically connected to the recording module, detects that the same judgment result appears three times consecutively within the recording module, the recording module, which is electrically connected to the counting module, transmits the judgment result to the report generation module. The report generation module generates an equipment problem warning report, which is displayed on the human-machine interface structure electrically connected to the output end of the report generation module. This reminds the staff to repair the conveying capping device and can generate unqualified test results in a timely manner, making it convenient for the staff to adjust production and stop losses in time.

[0029] This invention provides a continuous conveying capping device for beverage bottle caps and a capping qualification rate monitoring system thereof.

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The equipment includes a housing 1, a display screen 2, a packaging feeding structure 3, a pushing structure 4, a packaging conveying structure 5, a first limit conveying structure 6, a second limit conveying structure 7, a bottle cap conveying structure 8, a bottle cap conveying diversion structure 10, a bottle cap feeding structure 11, an adhesive coating structure 12, and a camera 15, forming a capping and conveying device. Multiple clamping structures 9 are fixedly installed on the outside of the bottle cap conveying structure 8. Each clamping structure 9 includes a triangular plate 901 and a clamping head 904. A telescopic hydraulic cylinder 902 and a liquid storage tank 906 are fixedly connected to the outside of the triangular plate 901. Inside 906 is a piston plate 907, which is fixedly connected to a solenoid valve 908 and a bend 909. One end of the bend 909 is connected to a hydraulic telescopic rod 912. A motion box 921 is fixedly sleeved on the outside of the hydraulic telescopic rod 912. A clamping member 916 is slidably arranged inside the motion box 921. A second pressure sensor 922 and multiple springs 919 are arranged on the outside of the clamping member 916. A connecting frame is slidably arranged between one end of the hydraulic telescopic rod 912 and the clamping member 916. A first pressure sensor 905 is fixedly connected inside the clamping head 904.

[0031] Specifically, a CNC program is pre-input and stored inside the display screen 2. The display screen 2 controls the operation of the packaging feeding structure 3, the pushing structure 4, the packaging conveying structure 5, the first limit conveying structure 6, the second limit conveying structure 7, the bottle cap conveying structure 8, the bottle cap conveying diversion structure 10, the bottle cap feeding structure 11, and the gluing structure 12 through the CNC program. Multiple bottle caps 14 glued together form a set of bottle caps 14. The working bottle cap feeding structure 11 transports a set of bottle caps 14 to the bottle cap conveying diversion structure 10. The working bottle cap conveying diversion structure 10 moves from a set of bottle caps 14... After the bottle caps 14 are separated one by one, they are transported. When the bottle cap 14 transported by the bottle cap conveying and diverting structure 10 moves to the bottom of the glue coating structure 12, the glue coating structure 12 applies glue to the bottle cap 14. The bottle cap 14 after being coated with glue is transported by the bottle cap conveying and diverting structure 10 and then transported to the clamping structure 9 of the bottle cap conveying structure 8. Subsequently, the clamping structure 9 works for the first time to clamp and fix the bottle cap 14 after being coated with glue. The bottle cap conveying structure 8 transports the clamping structure 9, which serves to transport the bottle cap 14 after being coated with glue.

[0032] After multiple outer packages 13 are transported into the equipment housing 1 by the packaging feeding structure 3, the pushing structure 4 installed on top of the packaging feeding structure 3 periodically conveys the outer packages 13 from the top of the packaging feeding structure 3 to the top of the packaging conveying structure 5. The packaging conveying structure 5 transports bottle caps 14. By controlling the working speed of the pushing structure 4, the packaging conveying structure 5, the bottle cap conveying diversion structure 10, the gluing structure 12, and the bottle cap conveying structure 8, the bottle caps 14 with glue applied, transported by the bottle cap conveying structure 8, move to the bottom of the bottle cap conveying structure 8, align with the top of the outer packages 13 transported by the packaging conveying structure 5, and move at the same speed and in the same direction while remaining relatively stationary. A second limiting conveying structure 7 and a first limiting conveying structure 6 are symmetrically arranged on the top of the packaging conveying structure 5. The second limiting conveying structure 7 and the first limiting conveying structure 6 separate the multiple outer packages 13, preventing the situation where one outer package 13 breaks and the internal beverage contaminates the other outer packages 13.

[0033] After the bottle cap 14 enters the gripping head 904, when the gripping structure 9 works for the first time, the telescopic hydraulic cylinder 902, which is fixedly connected between the triangular plate 901 and the gripping head 904, works for the first time. The telescopic hydraulic cylinder 902 extends and pushes the gripping head 904 to move away from the triangular plate 901. Since the triangular plate 901 is fixedly installed on the outside of the bottle cap conveying structure 8, the gripping head 904 moves away from the bottle cap conveying structure 8 at this time.

[0034] Since the bent tube 909 is fixedly connected to the bottom of the piston plate 907 and the clamping head 904, when the clamping head 904 moves away from the triangular plate 901, the clamping head 904 will drive the piston plate 907 to move through the bent tube 909, and the piston plate 907 located inside the liquid storage tank 906 will move away from the triangular plate 901. The liquid in the piston plate 907, away from the triangular plate 901, is squeezed, and the hydraulic pressure rises. The increased liquid enters the bend 909 through the guide groove 910 on the top of the outer side of the bend 909. A connecting pipe 911 is fixedly connected between the bend 909 and the hydraulic telescopic rod 912. Therefore, the high-pressure liquid enters the hydraulic telescopic rod 912 through the bend 909 and the connecting pipe 911. The hydraulic pressure inside the hydraulic telescopic rod 912 rises and extends. The hydraulic telescopic rod 912 pushes the transmission plate 913, which is fixed at one end, to move. Since multiple connecting rods 914 are fixedly connected between the two transmission plates 913, the two transmission plates 913 move synchronously at this time, pushing the clamping member 916 away from the inside of the motion box 921. The clamping member 916 clamps and fixes the bottle cap 14 into the clamping head 904, thus clamping and fixing the bottle cap 14 that has entered the clamping head 904.

[0035] Since mounting plates 917 are fixedly connected between the two sides of the outer jacket 915 and the clamping member 916, and a sliding plate 918 is slidably installed on one side of the mounting plate 917, the mounting plate 917 is limited by the sliding plate 918 installed inside the motion box 921 by the second telescopic rod 920, and the clamping member 916 can move up and down on one side of the sliding plate 918.

[0036] The sliding plate 918 installed on the telescopic second telescopic rod 920 can move left and right, that is, the clamping member 916 can move left and right.

[0037] After the bottle cap 14, which is held and fixed by the clamping structure 9, is aligned with the outer packaging 13, the clamping structure 9 and the bottle cap 14 move in the same direction at the same speed, and the bottle cap 14 and the outer packaging 13 are in a relatively stationary state. At this time, the display screen 2 controls the clamping structure 9 to perform a second operation. At this time, the telescopic hydraulic cylinder 902 pushes the clamping head 904 to move a distance away from the triangular plate 901, pressing the bottle cap 14 onto the top of the outer packaging 13. When the telescopic hydraulic cylinder 902 is working, the display screen 2 controls the solenoid valve 908 fixed by the piston plate 907 to open for a period of time. At this time, the liquid on both sides of the piston plate 907 can be connected, and the downward speed of the piston plate 907 is in balance with the speed of the liquid passing through the solenoid valve 908. Therefore, the hydraulic pressure inside the liquid storage tank 906 will not increase due to the downward movement of the piston plate 907, and the hydraulic telescopic rod 912 will not extend to pressurize the bottle cap 14. The display screen 2 controls the telescopic hydraulic cylinder 902 and the liquid storage tank 906 to stop working at a time, pressing the bottle cap 14 onto the outer packaging 13. After the adhesive on the bottle cap 14 solidifies, the bottle cap 14 and the outer packaging 13 are fixed together.

[0038] Subsequently, the display screen 2 controls the solenoid valve 908 to open for a period of time and then close. While the piston plate 907 remains stationary, during the open period of the solenoid valve 908, the liquid inside the bend 909 and the hydraulic telescopic rod 912 leaks out through the guide groove 910 and the solenoid valve 908, reducing the hydraulic pressure inside the hydraulic telescopic rod 912. The spring 919 fixed between the transmission plate 913 and the motion box 921 rebounds and contracts, causing the transmission plate 913 to move a certain distance away from the clamping member 916. The transmission plate 913's movement distance is limited, and it does not contact the outer casing 915, so the clamping member 916 is not moved by the transmission plate 913 at this time. Meanwhile, the multiple springs 919 fixed between the sliding plate 918 and the motion box 921 push the clamping member 916, applying a certain pressure to it, creating friction between the clamping member 916 and the bottle cap 14.

[0039] When the bottle cap 14 and outer packaging 13 move into the field of view of the camera 15, the display screen 2 controls the clamping structure 9 to operate for the third time. The telescopic hydraulic cylinder 902 pushes the clamping head 904 away from the triangular plate 901 for the third time, applying a certain pressure to the bottle cap 14. Since part of the bottle cap 14 is in contact with the first pressure sensor 905, it applies pressure to one side of the top of the bottle cap 14. The bottle cap 14 and the bottom outer packaging 13 are subjected to force. After detecting the local force on the bottle cap 14 and the local deformation of the outer packaging 13, the system detects whether the bottle cap 14 separates from the outer packaging 13 and whether the beverage inside the outer packaging 13 is sprayed out. The first pressure sensor 905 detects the pressure value applied to the bottle cap 14 and outer packaging 13 by the clamping head 904. When the pressure applied to the bottle cap 14 and outer packaging 13 reaches the preset value, the display screen 2, which is electrically connected to the first pressure sensor 905, controls the telescopic hydraulic cylinder 902 to stop working. During this process, the displacement distance of the clamping head 904 is extremely small, and the movement distance of the piston plate 907 is extremely small. Therefore, even if the hydraulic telescopic rod 912 extends, it will not push the transmission plate 913 to contact the clamping part 916.

[0040] Subsequently, the display screen 2 controls the clamping structure 9 to perform a fourth operation. The telescopic hydraulic cylinder 902 operates again, driving the clamping head 904 to move closer to the triangular plate 901. At this time, multiple springs 919 apply a certain pressure to the clamping member 916, creating friction between the clamping member 916 and the bottle cap 14. The upward-moving clamping head 904, through the bent pipe 909 and the hydraulic telescopic rod 912, drives the motion box 921 to move upward (as described above and below in this application). Figure 3 Based on the reference, the friction between the clamping member 916, which can move up and down, and the bottle cap 14 causes the clamping member 916 to apply an upward force to the bottle cap 14. The bottom of the clamping member 916 is provided with a second pressure sensor 922, which detects the downward reaction force on the clamping member 916. This serves to detect whether the bottle cap 14 separates from the outer packaging 13 when it is subjected to an upward force within a certain range. Therefore, the clamping structure 9 can convert the pushing and pulling force of the telescopic hydraulic cylinder 902 controlling the position of the clamping head 904 into a force to detect whether the outer packaging 13 and the bottle cap 14 are properly pressed together, and promptly detect the processing pass rate. When consecutive failures occur, the staff can stop the loss in time.

[0041] Furthermore, the friction between the clamping member 916 and the bottle cap 14 is much less than the force that drives the clamping head 904 to move driven by the telescopic hydraulic cylinder 902, so the clamping member 916 can move away from the outside of the bottle cap 14. While the telescopic hydraulic cylinder 902 is working, the piston plate 907 moves synchronously, and the hydraulic pressure inside the reservoir 906 changes. When the clamping member 916 leaves the outside of the bottle cap 14, the hydraulic telescopic rod 912 retracts, causing the transmission plate 913 near the clamping member 916 to contact the outer sleeve 915. Subsequently, the solenoid valve 908 opens, and the pressure inside the hydraulic telescopic rod 912 returns to normal. The spring 919 fixed between the sliding plate 918 and the motion box 921 rebounds completely, and the transmission plate 913, which is away from the hydraulic telescopic rod 912, pushes the outer sleeve 915. The outer sleeve 915, through the mounting plate 917, causes the clamping member 916 to move away from the first pressure sensor 905. The clamping head 904 moves away from the bottle cap 14 as a whole, the hydraulic pressure inside the reservoir 906 returns to normal, the solenoid valve 908 closes, the clamping structure 9 returns to its initial state, and is moved by the bottle cap conveying structure 8 to proceed to the next working process.

[0042] Other, such as Figure 3 As shown, a telescopic first telescopic rod 903 is fixedly connected between the triangular plate 901 and the clamping head 904. The first telescopic rod 903 provides limiting support for the clamping head 904, reducing the forces generated by gravity, movement, pressure, etc., at the installation positions of the telescopic hydraulic cylinder 902 and the clamping head 904, and protecting the installation of the telescopic hydraulic cylinder 902 and the clamping head 904.

[0043] Other, such as Figure 4 As shown, since one end of the bend 909 passes through the liquid storage tank 906, the bend 909, which moves synchronously with the clamping head 904, drives the piston plate 907 to move inside the liquid storage tank 906. The sealing structure between the liquid storage tank 906 and the bend 909 that does not affect the sliding of the bend 909 is a common technical means and no specific restrictions are imposed.

[0044] Other, such as Figure 5 As shown, bearings are rotatably sleeved on the outer sides of multiple connecting rods 914. Therefore, during the movement of the clamping member 916 driving the outer sleeve 915, the bearings play a role in reducing resistance and ensuring the accuracy of the detection by the second pressure sensor 922.

[0045] Please see Figure 9 and Figure 10The press-fit qualification rate monitoring system includes a human-machine interface structure 201. The output end of the human-machine interface structure 201 is electrically connected to a data storage module 202. The output end of the data storage module 202 is electrically connected to a control module 203 and an image analysis module 204. The output end of the control module 203 is electrically connected to a data analysis module 205. The output end of the data analysis module 205 is electrically connected to a recording module 206. The output end of the recording module 206 is electrically connected to a three-dimensional coordinate analysis module 208 and a report generation module 209. The output end of the image analysis module 204 is electrically connected to a counting module 207.

[0046] The operator inputs the CNC program into the human-machine interface structure 201. After the CNC program is stored in the data storage module 202, the control module 203, which is electrically connected to the output of the data storage module 202, controls the operation of the packaging feeding structure 3, the pushing structure 4, the packaging conveying structure 5, the first limit conveying structure 6, the second limit conveying structure 7, the bottle cap conveying structure 8, the bottle cap conveying diversion structure 10, the bottle cap feeding structure 11, the glue coating structure 12, and other structures through the CNC program.

[0047] The working camera 15 captures images of the outer packaging 13 and bottle cap 14 between the second limiting conveying structure 7 and the packaging conveying structure 5. The images captured by the camera 15 are transmitted to the image analysis module 204. When the image analysis module 204 detects a new clamping structure 9, outer packaging 13 and bottle cap 14 in the image, the control module 203, which is electrically connected to the image analysis module 204, controls the clamping structure 9 to perform a third and fourth operation in sequence. This serves to detect whether the bottle cap 14 separates from the outer packaging 13 after local stress and deformation of the outer packaging 13, whether the beverage inside the outer packaging 13 is sprayed out, and whether the bottle cap 14 separates from the outer packaging 13 when subjected to a certain degree of upward force.

[0048] The camera 15 captures images of the outer packaging 13 and the bottle cap 14. The image analysis module 204 analyzes whether the beverage sprays out, whether there is a crack between the bottle cap 14 and the outer packaging 13, or whether the bottle cap 14 and the outer packaging 13 separate. When the above situations occur, the image analysis module 204 captures the corresponding image and sends it to the trace analysis unit 2051, which is electrically connected to the output end. The trace analysis unit 2051 analyzes the motion trajectory data of the bottle cap 14 and the trajectory data of the beverage in the image. The trajectory data is sent by the trace analysis unit 2051 to the cause analysis unit 2053, which is electrically connected. The first pressure sensor 905 and the second pressure sensor 922 detect the data and send it to the data analysis unit 2052. The data analysis unit 2052 analyzes the data changes and sends the analysis results to the cause analysis unit 2053, which is electrically connected to the delivery end.

[0049] The cause analysis unit 2053 analyzes the reasons for the problem. For example, if the beverage inside the outer packaging 13 sprays out during the increase of data from the first pressure sensor 905, the cause analysis unit 2053 generates a result indicating that the adhesive fixation between the bottle cap 14 and the outer packaging 13 has failed. Alternatively, if the data from the first pressure sensor 905 is stable and a gap appears between the bottle cap 14 and the outer packaging 13 under pressure on one side, the cause analysis unit 2053 generates a result indicating that the adhesive on the bottle cap 14 is uneven. Or, if the bottle cap 14 separates from the outer packaging 13 during the change of data from the second pressure sensor 922, the cause analysis unit 2053 will generate a result indicating that the adhesive on the bottle cap 14 is uneven. 3. The result of the failure of the glue application on the bottle cap 14 is generated; and the result of the cause analysis unit 2053 is sent to the recording module 206, which is electrically connected, for storage. When the counting module 207, which is electrically connected to the recording module 206, detects that the same judgment result appears three times in a row, the counting module 207, which is electrically connected to the recording module 206, sends the judgment result to the report generation module 209. The report generation module 209 generates an equipment problem warning report. The problem warning report is displayed on the human-machine interaction structure 201, which is electrically connected to the output end of the report generation module 209, to remind the staff to perform maintenance on the capping equipment.

[0050] Meanwhile, the number of bottle caps 14 captured by the image analysis module 204 is recorded by the counting module 207 electrically connected to the output of the image analysis module 204. After the bottle caps 14 are pressed onto the outer packaging 13 in a certain stage, the total number of times recorded inside the counting module 207 is sent to the recording module 206. The recording module 206 calculates the number of times the processing has problems in a certain stage based on the total number of times and the records of problems, and obtains the pass rate of processing, so as to help the staff adjust and arrange the operation of the capping equipment.

[0051] Since the output of the image analysis module 204 is electrically connected to the three-dimensional coordinate analysis module 208, the images captured by the image analysis module 204 are transmitted to the three-dimensional coordinate analysis module 208. The three-dimensional coordinate analysis module 208 generates three-dimensional distance data between two adjacent bottle caps 14 and between the bottle cap 14 and the outer packaging 13 based on the captured images. It analyzes whether the distance between the two bottle caps 14 meets the preset, or whether the positional relationship between the bottle cap 14 and the outer packaging 13 meets the preset. When the same result of not meeting the preset occurs twice in a row, the report generation module 209, which is electrically connected to the three-dimensional coordinate analysis module 208, generates a report on the operation of the bottle cap conveying structure 8, the packaging conveying structure 5, or the pushing structure 4. The report is displayed on the human-machine interaction structure 201, which makes it convenient for staff to process and adjust the operation of the conveying capping equipment or the CNC program in a timely manner, thereby reducing economic losses.
