Description

Technical Field

[0001] The invention relates to the technical field of industrial automation detection, and in particular to an adaptive mixed production bottle mouth detection method. Background Art

[0002] In the production process of glass bottles (or porcelain bottles), defects such as cracks and gaps often appear. Glass bottles with these defects seriously affect the transportation and preservation of products.

[0003] The applicant has previously applied for a large number of equipment for bottleneck / bottle mouth detection to improve the efficiency of bottle quality detection. For example, the application document with application number CN202111260527.4 previously applied by the applicant discloses a linear follow-up bottle mouth crack detection system, which drives the rotating module to move with the bottle body through a reciprocating follow-up module, and completes the collection of glass bottle mouth pattern information through rotation during the movement, and finally completes the detection of bottle mouth defects. For example, the application document with application number CN201720728586.2 previously applied by the applicant discloses a glass container manufacturing neck crack defect visual detection system, which can see the characteristics of the neck 360 degrees without dead angles by collecting images of the neck of the glass container, and finally completes the detection of bottleneck defects. The above-mentioned bottleneck / bottle mouth detection system is usually directly set on the glass bottle production line to perform defect detection on the glass bottles on the production line, and finally ensure the detection efficiency of the glass bottles.

[0004] However, since the above-mentioned bottleneck / bottle mouth detection equipment is directly used to cooperate with the glass bottle production line, whether it is the follow-up design disclosed by the above-mentioned linear follow-up bottle mouth crack detection system, or the bottleneck detection method above the glass bottle disclosed by the above-mentioned glass container manufacturing neck crack defect visual detection system, the objects to be detected can only be glass bottles of a single specification. When it is necessary to detect glass bottles of different specifications, it is necessary to disassemble and adjust them again, resulting in poor overall detection practicability and certain limitations in the detection range. Summary of the invention

The structure of the mixed inspection line is described in detail below.

[0055] In this embodiment, combined with Figure 2The conveying system 1 includes a conveying frame 11 and a plurality of conveyor belts 12 arranged in parallel on the upper side thereof. A frame-shaped fixing frame 13 is also arranged on the upper side of the conveying frame 11, and a plurality of bottle unscrambling devices 14 arranged above the conveyor belts 12 and corresponding to the plurality of conveyor belts 12 are arranged inside the fixing frame 13. Bottles of different kinds can be transported sequentially along different conveyor belts 12 under the action of the bottle unscrambling devices 14.

[0056] Specifically speaking, the structure of the bottle unscrambling device 14 includes two baffles 141 arranged opposite to each other. The two baffles 141 are strip-shaped plate structures arranged along the conveying direction of the conveyor belt 12, and a conveying channel capable of accommodating the bottles to be inspected is formed between the two baffles 141. The bottles can be transported along the conveying channel under the action of the conveyor belt 12, and a bottle stopping mechanism 142 capable of stopping the bottles is also provided at the end position of the conveying channel.

[0057] As a preferred embodiment, the distance between the two baffles 141 of the same bottle unscrambling device 14 is adjustable, so that when the types of bottles are different, the bottles can be better transported between the two baffles 141 along the conveyor belt 12 by adjusting the distance between the two baffles 141, ultimately ensuring that the conveying of different types of bottles can be completed smoothly and orderly.

[0058] As a further preference, in order to ensure the bottle stopping effect of the bottle stopping mechanism 142, so that the bottle stopping mechanism 142 can respond quickly and complete the stopping work of the bottle body, and prevent the bottle stopping mechanism 142 from damaging the bottle body, the bottle stopping mechanism 142 is configured to include two vertical plates arranged opposite to each other, the upper ends of the two vertical plates are connected to the fixing frame 13, and bottle stopping air bags are provided on the opposite sides, the bottle stopping mechanism 142 also includes a gas cylinder hung on one side of the conveying frame 11, which is connected to the bottle stopping air bag through a control valve, and is configured to complete the inflation work of the bottle stopping air bag, and finally the bottle body is clamped / blocked by the bottle stopping air bag to complete the stopping work of the bottle body.

[0059] Specifically speaking, the structure of the bottle-stopping airbag includes a block-shaped bag body, a cavity is provided on one side of the bag body, and a bag membrane which can swell under the action of the gas cylinder is provided at the opening of the cavity, the gas cylinder is connected to the cavity of the bag body, a slot is provided on the vertical plate, and the bag body can be detachably arranged in the slot, so that when the bottle-stopping airbag fails or is damaged, the disassembly, assembly and replacement work can be completed more conveniently.

[0060] In order to further ensure the stopping effect of the bottle stopping airbag on the bottle body and to enable the bottle stopping work to be successfully completed by the bottle stopping airbag when the bottle body heights are different, a plurality of bottle stopping airbags are vertically arranged on the same vertical plate.

[0061] To further ensure the stopping effect of the bottle-stopping airbag on different types of bottles, the upper end of the vertical plate is slidably connected to the fixing frame 13, and the sliding direction is perpendicular to the transport direction of the conveyor belt 12, so that the lateral spacing between the two vertical plates arranged opposite to each other is finally adjustable.

[0062] Specifically speaking, the adjustment method of the baffle 141 and the vertical plate is as follows: one end of the baffle 141 close to the head end of the conveyor belt 12 is horizontally slidably connected to the fixed frame 13, and the other end is fixed to one side of the vertical plate. Both ends of the fixed frame 13 along the transportation direction of the conveyor belt 12 are horizontally provided with screw thread shafts perpendicular to the transportation direction of the conveyor belt 12. The upper end of the vertical plate and the end of the baffle 141 close to the head end of the conveyor belt 12 are respectively screwedly connected to the threaded shafts at both ends of the fixed frame 13. By rotating the threaded shafts, the spacing between the two baffles 141 and the two vertical plates can be adjusted. In order to enable the threaded shafts at both ends of the fixed frame 13 to rotate synchronously, and then the spacing between the two baffles 141 and the two vertical plates can be synchronously adjusted, a synchronous belt is provided between the two corresponding front and rear threaded shafts.

[0063] Furthermore, a bottle full prompting mechanism 143 is provided on the baffle 141 on one side of the same bottle unscrambling device 14. The bottle full prompting mechanism 143 can prompt when the bottles in the conveying channel are full, thereby preventing too many bottles from piling up in the conveying channel and affecting the conveying of the bottles.

[0064] Combination Figure 3Specifically, the structure of the bottle full prompt mechanism 143 includes a mounting frame 1431 arranged on the outer side of the baffle plate 141, a horizontal axis 1432 is horizontally arranged on the upper side of the mounting frame 1431, and the axis of the horizontal axis 1432 is parallel to the conveying direction of the conveyor belt 12, and the bottle full prompt mechanism 143 also includes a strip-shaped follower plate 1433, which is vertically arranged, and the upper end is fixed to the middle part of the horizontal axis 1432, the baffle plate 141 is provided with an opening at the position below the fixing frame 13, the lower end of the follower plate 1433 is bent toward the conveying channel and extends into the conveying channel through the opening, and a follower rod 1434 is horizontally arranged at one end inside the conveying channel, the middle part of the follower rod 1434 is fixed to the follower plate 1433, and both ends are bent toward the baffle plate 141, and a tension spring / spring is also provided between the horizontal axis 1432 / follower plate 1433 and the mounting frame 1431, and the The follower plate 1433 is configured to have a movement tendency toward the baffle 141 under the action of the tension spring / spring, a detection plate 1435 is further provided on the rotating shaft, and a photoelectric element 1436 is provided on the fixing frame 13. The detection plate 1435 is configured so that when the lower end of the follower plate 1433 rotates out of the opening, it just reaches the position of the photoelectric element 1436. On the basis of the above structure, when the bottle body passes through the position of the bottle full prompt mechanism 143 from the conveying channel, the follower rod 1434 can be squeezed outwardly to make the lower end of the follower plate 1433 rotate outward. After the bottle body passes, the end of the follower plate 1433 is evenly re-entered into the conveying channel under the action of the tension spring / spring. At this time, the detection plate 1435 only triggers the photoelectric detection signal once. If the conveying channel is full of bottles, there is a situation where the bottles always squeeze the lower end of the follower plate 1433, and the detection plate 1435 is always at the position of the photoelectric element 1436, thereby completing the bottle full prompt work.

[0065] It should be noted that the conveyor belt 12 includes a secondary belt and a main belt corresponding to the detection system 2. In this embodiment, three conveyor belts 12 are set as an example. The middle conveyor belt 12 is the main belt, and the conveyor belts 12 on both sides are secondary belts. The conveying system 1 also includes a transfer mechanism, which is configured to transfer the bottles transported from the end of any conveying channel to the middle main belt.

[0066] As for the position and structure of the transfer mechanism, it is located on one side of the fixed frame 13 along the transport direction of the conveyor belt 12, and is an eight-shaped structure composed of two feed-sliding plates with an opening facing the fixed frame 13. One end of the two feed-sliding plates close to the fixed frame 13 is located on the outside of the outermost conveyor belt 12, and the other ends are located on both sides of the main belt. Based on the above structure, when the bottle body is transported with the conveyor belt 12, it can be concentrated on the main belt under the action of the two feed-sliding plates, and finally the bottle body transportation work to the detection system 2 is completed through the main belt.

[0067] In this embodiment, combined with Figure 4The detection system 2 includes a detection belt 21 corresponding to the end of the main belt, and a bottleneck detection device 22 and a bottle mouth detection device 23 which are successively arranged along the transportation direction of the detection belt 21.

[0068] Combination Figure 6 Specifically, the bottleneck detection device 22 includes a first detection frame 221 of a frame structure, the detection belt 21 is set through the first detection frame 221, and the first detection frame 221 is provided with a bottleneck detection mechanism 223 for bottle bottleneck detection.

The bottleneck detection unit 2232 can be a glass container manufacturing neck crack defect visual inspection system 2 disclosed in the applicant's previous application document with application number CN201720728586.2. No further elaboration is made here. In order to adapt to the bottleneck detection work of bottles of different heights, the bottleneck detection unit 2232 is slidably arranged on the neck inspection fixed frame 2231 in a liftable manner.

[0070] As a preferred embodiment, the bottleneck detection device 22 further includes a centering mechanism 222 disposed on both sides of the detection belt 21 in front of the bottleneck detection unit 2232, combined with Figure 5 Specifically, the centering mechanism 222 includes a centering fixing frame 2221 disposed outside the detection belt 21 and a bottle body centering frame 2222 disposed above the centering frame 2222. A plurality of centering wheels 2225 are disposed on the side of the bottle body centering frame 2222 close to the detection belt 21 along the conveying direction of the neck detection belt. A plurality of centering wheels 2225 are disposed on the side away from the conveying direction of the detection belt 21 and away from the detection belt 21.

The centering belt 2227, the centering mechanism 222 also includes a centering motor 2224, which is connected to the centering belt 2227 in transmission. On the basis of the above structure, the centering belt 2227 between the collecting wheels 2226 and the centering wheels 2225 of the centering mechanisms 222 on both sides is in an eight-shaped structure with its opening facing away from the conveying direction of the detection belt 21, so that when the position of the bottle body is offset along the transportation of the detection belt 21, the bottle body can be straightened by the centering mechanism 222, ultimately ensuring that the bottleneck detection work can be successfully completed.

[0071] As a further preference, in order to adapt to the final operation of different types of bottles, the bottle body centering frame 2222 is connected to the centering fixed frame 2221 in a transverse sliding manner, and the sliding direction is perpendicular to the conveying direction of the detection belt 21. The centering mechanism 222 also includes a transverse adjustment motor 2223, which is configured to complete the position adjustment of the bottle body centering frame 2222.

[0073] Specifically, the structure of the bottle mouth detection mechanism 232 includes a hanging frame 2321 located above the detection belt 21 and fixed to the second detection frame 231, and a bottle mouth detection unit 2322 is hung on the lower side of the hanging frame 2321. The bottle mouth detection unit 2322 can be a linear follow-up bottle mouth crack detection system 2 disclosed in the applicant's previous application document with application number CN202111260527.4.
