Description

Technical Field

[0001] This utility model relates to the field of glass bottle defect detection technology, specifically to a bottle body transfer device for a glass bottle defect detection machine. Background Technology

[0002] During glass bottle production, cracks may appear on the bottle body (especially at the mouth and neck). To detect these cracks, the current method involves taking photographs and processing the images. However, since defects like cracks in glass bottles do not always appear in the same area, traditional image processing methods suffer from low reliability.

[0003] To improve the detection accuracy of crack defects, the commonly used detection scheme is to detect cracks by utilizing the difference in light reflection and refraction between cracked and intact parts of the bottle. Specifically, a turntable is set up with multiple detection positions arranged around its circumference. In each detection position, multiple light-receiving parts with different angles are arranged, and a light-emitting part (i.e., light source) is set up corresponding to the light-receiving part. After the glass bottle is transferred to the turntable, it passes through each detection position in sequence as the turntable rotates. At each detection position, the glass bottle also rotates at a certain angle on the surface of the turntable. After passing through all the detection positions, the bottle body completes one full rotation, thus realizing the detection of the bottle body around its entire circumference. When there is a crack in the bottle body, the reflected light will be detected by a light-receiving part at a certain detection position, so that it can be rejected in subsequent processing (such as the technical solution described in the Chinese Utility Model Patent with application number 202120853256.2, application date April 23, 2021, and patent name "Automatic Inspection Machine", and the technical solution described in the PCT Invention Patent with application number 202210462656.X, application date February 6, 2017, and patent name "Inspection Device for Glass Bottle").

[0004] In the above-mentioned testing scheme, one step is to transfer the glass bottles to be tested from the production line to the turntable mentioned above, and after the test is completed, transfer the glass bottles to the subsequent process. Traditional transfer methods include the following: (1) Belt conveyor. That is, the glass bottles are transferred by belts that are set up opposite each other and rotate in the same direction, such as the technical solution recorded in the Chinese invention patent with application number 202310163759.0, application date February 24, 2023, and patent name "A bottle body servo camera detection device", and the technical solution recorded in the Chinese invention patent with application number 202210307420.9, application date March 25, 2022, and patent name "A glass bottle inspection machine". (2) Casing wheel conveyor. That is, the glass bottles are transferred to the edge of the casing wheel by casing wheels with casing grooves on the edge, and then the casing grooves are used to further realize the transfer or transfer.

[0005] However, the above-mentioned transfer method is more suitable for the transfer of round glass bottles. If the cross-section of the glass bottle to be tested is irregular (such as elliptical or rectangular), it is difficult to transfer the bottle body by the above method. Therefore, designing a technical solution that is suitable for the transfer of irregular bottle bodies (and also for round bottle bodies) in order to realize the crack detection of glass bottles has become an urgent problem to be solved in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bottle body transfer device for a glass bottle defect detection machine that achieves the transfer between glass bottles and the inspection machine through clamping and transfer, which is more conducive to the transfer of irregularly shaped bottles compared with the traditional method.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: the bottle body transfer device of the glass bottle defect detection machine includes an input device and an output device that are connected to the detection machine. The input device and the output device are respectively set at the entrance and the exit of the detection machine. The feature is that a transfer assembly is set in the detection machine, and the transfer assembly is provided with two transfer mechanisms for clamping and transferring the glass bottle: an input clamping mechanism and an output clamping mechanism.

[0025] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0026] like Figure 1 As shown, a bottle body transfer device for a glass bottle defect inspection machine includes an input device 3 and an output device 1 that are connected to the inspection machine 2. After the glass bottle to be tested is processed, it is sent into the inspection machine 2 through the input device 3. After crack detection is completed in the inspection machine 2, it is transferred to the output device 1 and output to the subsequent process by the output device 1.

[0027] Combination Figures 2-3 The testing machine 2 includes a testing platform 6 and a housing covering the testing platform 6. A testing turntable 9 is rotatably mounted on the surface of the testing platform 6. Multiple testing positions 5 are arranged on the outer side of the testing turntable 9, and multiple light-receiving parts are arranged in each testing position 5. A light source corresponding to the light-receiving parts is also provided inside the housing. Multiple rotating seats 23 (see...) are evenly arranged on the surface of the testing turntable 9. Figure 6The rotating seat 23 is rotatably mounted on the surface of the detection turntable 9. The method of rotating the detection turntable 9, the method of rotating the rotating seat 23 on its surface, the method of implementing the light-receiving part in each detection position 5, and the detection principle for glass bottle cracks are all common knowledge in the field (such as the technical solutions described in the Chinese utility model patent with application number 202120853256.2, application date April 23, 2021, entitled "Automatic Inspection Machine", and the technical solutions described in the PCT invention patent with application number 202210462656.X, application date February 6, 2017, entitled "Inspection Device for Glass Bottles"), and will not be repeated in this application.

[0028] A transfer assembly 8 is also provided on the surface of the testing table 6. The transfer assembly 8 is located on one side of the testing turntable 9. An inlet and an outlet are respectively provided on both sides of the housing. The transfer assembly 8 is located between the inlet and outlet of the housing. The input device 3 extends to the inlet of the housing and docks with one end of the transfer assembly 8. The output device 1 extends from the other side of the housing to the outlet of the housing and docks with the other end of the transfer assembly 8. The input device 3 is implemented by a conveyor belt driven by the input drive motor 7, and the output device 1 is implemented by a conveyor belt driven by the output drive motor 4.

[0029] The glass bottle to be tested is placed on the surface of the conveyor belt in the input device 3. The conveyor belt runs under the action of the input drive motor 7, sending the glass bottle to be tested into the entrance of the housing of the testing machine 2. The transfer component 8 transfers the glass bottle that has run to the end of the input device 3 to the rotating seat 23 on the surface of the testing turntable 9. As the glass bottle rotates with the testing turntable 9, it passes through each testing position 5 in sequence to complete the test. Then it runs to the exit of the output device 1. At this time, the transfer component 8 transfers the glass bottle that has completed the test to the surface of the conveyor belt of the output device 1. Driven by the output drive motor 4, the glass bottle is lowered and transferred out of the testing machine 2.

[0030] like Figures 4-5 As shown, the transfer assembly 8 includes a linear module 13 horizontally disposed on the surface of the inspection table 6. Two sliders are slidably disposed on the linear module 13, and an input translation frame 12 and an output translation frame 14 are respectively disposed on the surfaces of the two sliders. An input fixing seat 11 is installed on the surface of the input translation frame 12 near the input device 3. An input lifting cylinder 10 is installed on the end of the input fixing seat 11 facing the inspection turntable 9. An input lifting frame 20 is installed on the movable end of the input lifting cylinder 10. An input gripping cylinder 21 is horizontally fixed on the surface of the input lifting frame 20, and a set of input grippers 22 are disposed opposite to each other on the movable end of the input gripping cylinder 21.

[0031] An output mounting base 16 is installed on the surface of the output translation frame 14 near the output device 1. An output lifting cylinder 15 is installed on the end of the output mounting base 16 facing the detection turntable 9. An output lifting frame 17 is installed on the movable end of the output lifting cylinder 15. An output gripping cylinder 18 is horizontally fixed on the surface of the output lifting frame 17. A set of output grippers 19 are arranged opposite to the movable end of the output gripping cylinder 18.

[0032] The specific working process and working principle are as follows: Combination Figure 6 A through-beam sensor 24 is installed at the output end of the input device 3, with its input and output ends located on opposite sides of the output end of the input device 3. The glass bottle to be tested is placed on the surface of the conveyor belt in the input device 3. The conveyor belt runs under the action of the input drive motor 7, sending the glass bottle to be tested into the entrance of the testing machine 2 housing. When the glass bottle is conveyed to the end of the input device 3, it blocks the signal between the input and output ends of the through-beam sensor 24, at which point the input drive motor 7 stops running.

[0033] Simultaneously, the input translation frame 12 moves towards the output end of the input device 3 under the action of the corresponding slider. During (or before) the movement of the input translation frame 12, the input lifting cylinder 10 actuates, sending the input gripping cylinder 21 to its highest position. At the same time, the input gripping cylinder 21 actuates, causing its end-end input jaws 22 to open. At this time, the open input jaws 22 are directly above the glass bottle. The input lifting cylinder 10 resets, causing the input gripping cylinder 21 to descend to its lowest position. At this time, the input jaws 22 are located on both sides of the lower part of the glass bottle. The input gripping cylinder 21 resets, causing its end-end input jaws 22 to close, thus clamping the glass bottle.

[0034] The input lifting cylinder 10 actuates again, driving the input gripping cylinder 21 and the glass bottle to the highest position. The input translation frame 12 returns under the action of the corresponding slider, transferring the glass bottle directly above the rotating seat 23 on the surface of the detection turntable 9. The input lifting cylinder 10 resets again, causing the input gripping cylinder 21 and the glass bottle to descend, placing the glass bottle into the groove on the surface of the rotating seat 23. The input gripping cylinder 21 actuates again, opening its input gripper 22. The input lifting cylinder 10 actuates three times, driving the input gripping cylinder 21 to the highest position, separating the input gripper 22 from the glass bottle, and then grabbing the subsequent glass bottle on the surface of the output device 1.

[0035] After the glass bottle is transferred to the rotating seat 23 on the surface of the detection turntable 9, the glass bottle passes through each detection position 5 sequentially as the detection turntable 9 rotates, and then proceeds to the outlet of the output device 1. Because the detection turntable 9 rotates cyclically, while the glass bottle on the surface of the input device 3 is being grasped, one glass bottle simultaneously moves to the output device 1 after completion. Utilizing the same time interval, the transfer assembly 8 simultaneously completes the transfer of the glass bottle to the output device 1. Specifically: The output translation frame 14 moves towards the output end of the input device 3 under the action of the corresponding slider. During (or before) the movement of the output translation frame 14, the output lifting cylinder 15 actuates, sending the output gripping cylinder 18 to its highest position. At the same time, the output gripping cylinder 18 actuates, causing its end-end output jaws 19 to open. At this time, the open output jaws 19 are directly above the glass bottle. The output lifting cylinder 15 resets, causing the output gripping cylinder 18 to descend to its lowest position. At this time, the output jaws 19 are located on both sides of the lower part of the glass bottle. The output gripping cylinder 18 resets, causing its end-end output jaws 19 to close, thus clamping the glass bottle.

[0036] The output lifting cylinder 15 actuates again, driving the output gripping cylinder 18 and the glass bottle to the highest position. The output translation frame 14 returns under the action of the corresponding slider, transferring the glass bottle directly above the conveyor belt of the output device 1. The output lifting cylinder 15 resets again, causing the output gripping cylinder 18 and the glass bottle to descend, placing the glass bottle on the surface of the conveyor belt of the glass bottle output device 1. The output gripping cylinder 18 actuates again, opening its end gripper 19. The output lifting cylinder 15 actuates three times, driving the output gripping cylinder 18 to the highest position, separating the output gripper 19 from the glass bottle, and then grabbing the subsequent glass bottle on the surface of the detection turntable 9.

[0037] A counting sensor 25 is also provided at the output end of the input device 3. The counting sensor 25 is fixed to the surface of the inspection table 6 by the loom. The counting sensor 25 counts the glass bottles fed into the inspection machine 2 and tracks them for subsequent processing (such as rejecting defective glass bottles).

[0038] Meanwhile, the input gripper 22 and the output gripper 19 are detachably installed at the ends of the input gripping cylinder 21 and the output gripping cylinder 18, respectively. The input gripper 22 and the output gripper 19 have recesses inside to form grooves that conform to the contours of the glass bottles, so as to grip glass bottles of different shapes.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
