[0002] The sealing performance of milk-containing beverage bottles affects the shelf life of the beverage. After the beverage is filled and sealed, the sealing performance of the bottle needs to be tested. Optical sealing detection equipment can detect the external shape of the beverage bottle. Beverage bottles with surface deformation have poor sealing performance and need to be reprocessed. Some existing detection equipment has a slow detection efficiency and is not suitable for factory production lines.

[0003] To this end, a bottle cap sealing detection device with patent publication number CN203083794U includes a conveyor belt for conveying bottles, a bottle cap is provided at the bottle mouth of the bottle, and an optical detection device for detecting the height of the bottle cap; the optical detection device includes an infrared light source and an infrared beam receiving device respectively horizontally arranged on both sides of the conveyor belt, and the heights of the two are slightly higher than the bottle cap; the infrared light source emits an infrared beam, and the infrared beam receiving device at the other end receives the infrared beam and determines whether the bottle cap is loose by comparing it with a preset height value. If it is loose, it will trigger an alarm device connected to the optical detection device to alarm, with a simple structure, good accuracy and high detection efficiency.

[0004] However, beverage bottles generally have a cylindrical structure. During the optical inspection process, there are blind spots at some angles on the outside of the beverage bottles, which affects the accuracy of optical inspection.

[0021] 1. The present invention is provided with a rotating steering seat for adjusting the angles of the milk-containing beverage bottles corresponding to different inspection stations, and a plurality of limit grooves are provided on the feeding turntable. The milk-containing beverage bottles are transferred to the limit grooves and are rotated to different inspection stations by the rotating feeding turntable, and the feeding rotation controls the steering seat below the beverage bottle to rotate by the steering assembly when controlling the circular rotation of the beverage bottle.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figure 1-Figure 5As shown, a sealing detection device for milk-containing beverage bottles, a conveying frame 1 for conveying milk-containing beverage bottles in and out is installed on both sides of the sealing detection device, and the sealing detection device also includes a detection table 21 fixed between the two conveying frames 1, a protective cover 22 fixedly installed on the detection table 21, a feeding turntable 23 rotatably installed on the detection table 21, a plurality of fixed frames 24 fixed at equal angles on the detection table 21, an upper optical detection camera 25 installed on the upper end of the fixed frame 24, and a side optical detection camera 26 installed on the lower side of the fixed frame 24; a motor 31 is fixedly installed on the detection table 21, and the output end of the motor 31 is connected to the feeding turntable 23 Fixedly connected, a plurality of limit grooves 32 are provided at equal angles on the feeding turntable 23, a steering seat 33 is rotatably mounted in the feeding turntable 23, and a steering assembly 34 for driving the steering seat 33 to rotate is installed on the feeding turntable 23; a correction assembly 35 for adjusting the optical detection position of the dairy beverage bottles contained in the upper limit groove 32 of the feeding turntable 23 is installed on the fixed frame 24; the fixed frame 24 corresponds to the lateral position of the limit groove 32, and the upper optical detection camera 25 is correspondingly arranged at the position directly above the steering seat 33, and the two groups of limit grooves 32 on the feeding turntable 23 correspond to each other with the conveying frames 1 on both sides, respectively, so as to facilitate the feeding and discharging of dairy beverage bottles.

[0042] The milk-containing beverage bottles are placed on the conveyor rack 1 and transported to the feeding turntable 23, and the milk-containing beverage bottles enter a limiting groove 32 provided on the feeding turntable 23. The running motor 31 controls the rotation of the feeding turntable 23. The rotation of the feeding turntable 23 controls the circular rotation of the milk-containing beverage bottles in the limiting groove 32, so that the rotation of the milk-containing beverage bottles corresponds to different inspection stations in turn, and the beverage bottles are optically sealed by the upper optical inspection camera 25 and the side optical inspection camera 26. According to the deformation of the bottle body of the beverage bottle and the corresponding packaging of the bottle mouth, it is determined whether the beverage bottle is sealed. After multiple optical inspections, the feeding turntable 23 rotates so that the inspected beverage bottles correspond to the position at the exit of the inspection table 21, and the beverage bottles are controlled to enter the conveyor rack 1 at the exit of the inspection table 21, and the inspected beverage bottles are fed out autonomously.

[0043] During the rotation of the feeding turntable 23, the steering seat 33 embedded in the feeding turntable 23 is controlled by the steering assembly 34 to rotate. The steering seat 33 is supported at the lower position of the milk-containing beverage bottle. During the rotation of the steering seat 33, the milk-containing beverage bottle is driven to rotate synchronously. Therefore, when the milk-containing beverage bottle rotates in a circle to switch the detection station, the beverage bottle simultaneously rotates to adjust the angle of optical detection, thereby avoiding detection blind spots and improving the accuracy of the sealing detection of the equipment.

[0044] See also Figure 4-Figure 6As shown, the steering assembly 34 includes a fixed seat 341 fixed in the detection platform 21 and a support frame 343 fixed on the feeding turntable 23. A central gear ring 342 corresponding to the feeding turntable 23 is fixedly installed on the fixed seat 341. A large gear 344 is rotatably installed on the support frame 343. The large gear 344 is fixedly connected to the steering seat 33. A small gear 345 is meshingly assembled on the side of the large gear 344. The small gear 345 is rotatably mounted on the support frame 343. The small gear 345 is meshingly assembled with the central gear ring 342. A circular groove structure is provided at the bottom of the limiting groove 32 of the detection platform 21. The steering seat 33 is embedded in the circular groove and rotatably assembled in the detection platform 21. The steering seat 33 is embedded in the circular groove and rotated in the detection platform 21 under the transmission action of the steering assembly 34. A circular groove structure is provided at the center position of the central gear ring 342 and the fixed seat 341 so that the output shaft of the motor 31 can extend and be fixedly connected to the bottom of the feeding turntable 23.

[0045] When the motor 31 drives the feeding turntable 23 to rotate, the feeding turntable 23 drives multiple small gears 345 distributed on the bottom circumference to rotate in a circle. The small gears 345 are meshed and linked to the outer side of the center gear ring 342. When the small gears 345 rotate in a circle, they rotate by themselves through the meshing transmission structure with the center gear ring 342. The side of the small gear 345 is meshed and equipped with a large gear 344. Under the action of the meshing transmission structure, the large gear 344 also rotates. The large gear 344 is fixedly connected to the bottom of the steering seat 33. When it rotates, it drives the steering seat 33 to rotate synchronously, thereby rotating to adjust the optical detection angle of the beverage bottle on the steering seat 33.

[0046] See also Figure 4 , Figure 7-Figure 9 As shown, the correction component 35 includes a hollow guide block 351 fixed on the fixed frame 24, a guide rod 352 is slidably connected through the hollow guide block 351, a correction arc piece 353 is fixedly installed on the guide rod 352, a sliding frame 354 is fixedly installed on the guide rod 352, a sliding protrusion 355 is slidably connected in the sliding frame 354, and the sliding protrusion 355 is rotatably installed on the detection table 21.

[0047] When a beverage bottle in a limit groove 32 rotates to an inspection station, the sliding protrusion 355 of the inspection station rotates. When the sliding protrusion 355 rotates, the upper part passes through the sliding frame 354 to slide, pushing the sliding frame 354 to move linearly. At this time, the guide rod 352 passes through the hollow guide block 351 and slides back and forth. During the linear movement of the guide rod 352, it drives the side fixed correction arc piece 353 to move synchronously, so that the correction arc piece 353 pushes the beverage bottle toward the inner side of the limit groove 32, adjusts the position of the beverage bottle corresponding to the limit groove 32, thereby adjusting the optical detection position of the beverage bottle to maintain the accuracy of optical detection.

[0048] See also Figure 4 , Figure 7-Figure 9 As shown, a linkage assembly 36 for driving the sliding protrusion 355 to rotate is provided between the correction assembly 35 and the steering assembly 34 .

[0049] When the feeding turntable 23 rotates, the support frame 343 in the steering assembly 34 below it is fixed on the feeding turntable 23 and rotates in a circle. When the support frame 343 rotates in a circle, it can drive the correction assembly 35 through the linkage assembly 36, thereby adjusting the corresponding position of the beverage bottle in the feeding turntable 23.

[0050] See also Figure 4 , Figure 7-Figure 9 As shown, the linkage assembly 36 includes a disk 361 elastically rotatably mounted in the detection platform 21 through a scroll spring, a limiting column 362 is fixedly mounted on the disk 361, a driving gear 363 is fixedly connected to the disk 361, a driven gear 364 is meshingly assembled next to the driving gear 363, the driven gear 364 is rotatably mounted in the detection platform 21 and is coaxially fixedly connected to the sliding protrusion 355, a lever 365 is fixedly connected to the support frame 343 in the steering assembly 34, and the lever 365 rotates in a circle and contacts the outer arc surface of the limiting column 362.

[0051] When the lever 365 is rotated and separated from the limit column 362, the disc 361 is rotated and reset under the elastic tension of the spiral spring. When the disc 361 rotates, it drives the driving gear 363 fixed above to rotate synchronously. The side of the driving gear 363 is meshed and assembled with the side of the driven gear 364. Under the action of the meshing transmission structure, the driven gear 364 and the sliding protrusion 355 fixed above the driven gear 364 rotate. The sliding protrusion 355 above passes through the sliding frame 354 and slides inside to drive the guide rod 352 to move linearly.

[0052] See also Figure 4 and Figure 7 As shown, a through arc groove 37 is opened in the detection platform 21, and the lever 365 is fitted in the through arc groove 37 and rotates in a circle. The conveying frames 1 on both sides of the detection platform 21 are also provided with through arc grooves 37 to provide rotation space for the lever 365.

[0053] The limiting column 362 below the disk 361 corresponds to the through arc groove 37. When the lever 365 is fitted in the through arc groove 37 and rotates in a circle, the lever 365 contacts the side of the limiting column 362 to push the disk 361 to rotate.

[0054] See also Figure 3 and Fig.10 As shown, a loading assembly 4 and a hydraulic feeding assembly 5 for assisting the entry and exit of milk-containing beverage bottles are respectively installed at the connection position between the detection platform 21 and the two conveyor racks 1. The loading assembly 4 clamps the milk-containing beverage bottle and squeezes the bottle body when moving to assist the upper optical inspection camera 25 and the side optical inspection camera 26 in identifying leaking beverage bottles. The hydraulic feeding assembly 5 is composed of a hydraulic telescopic rod and a discharge plate, and the discharge plate corresponds to the discharge port position of the detection platform 21.

[0055] The loading assembly 4 can clamp the milk-containing beverage bottle on the conveying rack 1 and move it to the limiting groove 32 on the feeding turntable 23. The hydraulic feeding assembly 5 can push the milk-containing beverage bottle in the upper limiting groove 32 on the feeding turntable 23 to move onto the conveying rack 1, thereby realizing autonomous loading and unloading.

[0056] See also Figure 10-Figure 14 As shown, the feeding assembly 4 includes a screw slide 41 fixed on the detection table 21, a slide frame 42 is threadedly slidably assembled on the screw slide 41, a cylinder 43 is fixedly installed on the slide frame 42, a hollow column 44 is fixed on the telescopic end of the cylinder 43, an embedded rod 45 is telescopically connected to the hollow column 44, a clamping arc piece 46 is fixedly installed on the embedded rod 45, a hollow pressure piece 47 is slidingly sleeved on the embedded rod 45, a limiting spring 48 is connected between the hollow pressure piece 47 and the clamping arc piece 46, the screw slide 41 includes a rectangular frame for providing sliding of the slide frame 42 and a screw rotatably installed in the rectangular frame, the slide frame 42 and the screw are threadedly assembled, and the screw is connected to the output end of the small driver.

[0057] When the milk-containing beverage moves to the feeding port of the conveying rack 1 and the inspection table 21, the cylinder 43 is first operated to push the hollow column 44 to move in the direction of the beverage bottle. The clamping arc piece 46 on the side of the hollow column 44 is clamped on the outside of the beverage bottle. The side of the clamping arc piece 46 is elastically connected with a hollow pressing piece 47 through a limit spring 48. The hollow pressing piece 47 is slidably sleeved on the outside of the embedded rod 45, and the aperture of the sliding opening of the hollow pressing piece 47 is smaller than the outer diameter of the hollow column 44. Therefore, the hollow pressing piece 47 fits at the end position of the hollow column 44. The elastic structure of the limit spring 48 can limit the force of the clamping arc piece 46 clamping the outside of the beverage bottle. Then, the sliding frame 42 is controlled to slide and move through the screw slide 41, and the sliding frame 42 drives the clamped beverage bottle to move straightly to the limit groove 32 on the feeding turntable 23, thereby realizing the function of autonomous feeding.

[0058] See also Figure 11-Figure 14 As shown, a control arc plate 49 is fixedly installed on the hollow pressing piece 47, a rotating rod 410 is elastically rotatably installed on the screw slide 41 through a scroll spring, a cylindrical seat 411 is rotatably assembled on the rotating rod 410, and the hollow pressing piece 47 moves laterally to engage with the cylindrical seat 411.

[0059] When the slide frame 42 controls the linear movement of the beverage bottle for loading, the control arc plate 49 fixed on the side of the hollow pressing plate 47 moves synchronously. When the control arc plate 49 moves and engages with the outside of the cylindrical seat 411, it drives the cylindrical seat 411 to move sideways synchronously. At this time, the two ends of the rotating rod 410 connected between the cylindrical seat 411 and the screw slide 41 rotate accordingly. The rotating rod 410 rotates to push the engaged control arc plate 49 and the hollow pressing plate 47 to move in the direction of the clamped beverage bottle. The hollow pressing plate 47 is sleeved on the outside of the embedded rod 45 and slides. The hollow pressing plate 47 compresses the limit spring 48 to increase the force of the control arc plate 49 clamping the outside of the beverage bottle, thereby intensifying the external deformation strength of the beverage bottle in the leaking state, and assisting the upper optical detection camera 25 and the side optical detection camera 26 to identify the leaking beverage bottle.

[0060] See also Figure 1-Figure 14 As shown, the present invention also includes a method for detecting a milk-containing beverage bottle, which has the above-mentioned milk-containing beverage bottle sealing detection device, and includes the following steps:

[0061] S1, autonomous loading, the conveying frame 1 controls the milk-containing beverage bottles to be autonomously conveyed and moved to the feeding turntable 23, and the milk-containing beverage bottles are squeezed during the loading process to aggravate the deformation of the bottle body so that the optical detection camera can identify the leaking beverage bottles.

[0062] S2. Multi-angle visual recognition. The feed turntable 23 rotates so that the beverage bottles in the limit slots 32 move to different inspection stations in turn. Each inspection station is provided with an upper optical inspection camera 25 and a side optical inspection camera 26 for inspection. Whether the beverage bottle is sealed is quickly determined based on the deformation of the bottle body. When the feed turntable 23 rotates, the steering seat 33 is controlled to rotate through the steering assembly 34 so that different angles of the outside of the beverage bottle are optically inspected, thereby improving the inspection accuracy.

[0063] S3, position correction, when the feeding turntable 23 rotates to control the milk-containing beverage bottles to move to different inspection stations, the correction components 35 on each inspection station adjust the corresponding positions of the beverage bottles in the limiting grooves 32 to maintain the inspection accuracy.

[0064] S4, autonomous discharging, after being detected on the feeding turntable 23, the milk beverage bottles are moved to the conveying rack 1 and autonomously conveyed outward.

[0065] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
