[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: an empty bottle removing device, including: a conveyor belt 5, an actuator 1 for removing empty bottles is provided on the top of the conveyor belt 5, two groups of through-beam photoelectric sensors 4 are provided on the top of the actuator 1, a height adjustment component 2 is provided on the side of the actuator 1, and a diffuse reflection type photoelectric sensor 3 is provided on the top of the height adjustment component 2.

[0025] Further, when the conveyor belt 5 is started, the conveyor belt 5 drives the bottle body to move. The bottle body is located between the first limit plate 11 and the second limit plate 112 to prevent the bottle body from falling off the conveyor belt 5. When the bottle body passes through the diffuse reflection type photoelectric sensor 3, the diffuse reflection type photoelectric sensor 3 detects that the bottle body has passed and transmits the signal to the through-beam photoelectric sensor 4. The through-beam photoelectric sensor 4 detects whether the bottle body has contents and transmits the detection result to the actuator 1. The actuator 1 judges whether to alarm and remove or release and pass through according to the received signal.

[0026] The actuating mechanism 1 includes: a first limiting plate 11, one side of the first limiting plate 11 is hinged to one side of the baffle plate 12, a strip-shaped chute 15 is opened at the top of the baffle plate 12, the chute wall of the strip-shaped chute 15 is slidably connected to the outside of the slider 13, the top of the slider 13 is fixedly connected to the bottom of one end of the connecting rod 14, and the other end of the connecting rod 14 is fixedly connected to the top of the push plate 16. One side of the push plate 16 is fixedly connected to one end of the guide rod 111, and the other end of the guide rod 111 is fixedly connected to one side of the limiting block 19. The side part of the guide rod 111 is slidably inserted into the inside of the fixing plate 17, and both ends of the fixing plate 17 are fixedly connected to the outside of the second limiting plate 112. A return spring 110 is arranged between the fixing plate 17 and the limiting block 19, and the inner ring of the return spring 110 is slidably sleeved on the outside of the guide rod 111. The center position outside the fixing plate 17 is fixedly connected to the outside of the air cylinder 18, and the output shaft end of the air cylinder 18 is movably connected to the outside of the push plate 16.

[0027] Further, when the actuating mechanism 1 receives a signal to remove empty bottles, the output shaft of the air cylinder 18 extends and pushes the push plate 16 to move towards the baffle plate 12. At the same time, the push plate 16 also pushes the empty bottles towards the baffle plate 12. The push plate 16 pushes the baffle plate 12 to open through the connecting rod 14, so that a notch appears in the first limiting plate 11, and in this way, the empty bottles will be pushed away from the conveyor belt 5 from the notch, thus completing the removal of the empty bottles. When the push plate 16 moves towards the baffle plate 12, it also drives the limiting block 19 to move towards the fixing plate 17 through the guide rod 111, so that the limiting block 19 compresses the return spring 110. When the output shaft of the air cylinder 18 retracts, the return spring 110 will rebound and push the limiting block 19 away from the fixing plate 17. The limiting block 19 drives the push plate 16 to move towards the fixing plate 17 and return to the original position through the guide rod 111, and the push plate 16 drives the baffle plate 12 to return to the original position through the connecting rod 14 to ensure the normal passage of the bottles on the conveyor belt 5. Through the combined use of the above structure, the removal of empty bottles does not require manual intervention, the removal rate is higher, and the cost and the risk of omission are reduced.

[0028] The first limiting plate 11 is arranged on one side of the top of the conveyor belt 5, and the second limiting plate 112 is arranged on the other side of the top of the conveyor belt 5.

[0029] Further, the conveyor belt 5 drives the bottles to move, and the bottles are located between the first limiting plate 11 and the second limiting plate 112 to prevent the bottles from falling off the conveyor belt 5.

[0030] The height adjustment assembly 2 includes: a sleeve 22, one side of the sleeve 22 is fixedly connected to the outside of the second limiting plate 112, the inner wall of the sleeve 22 is slidably sleeved on the outside of the lifting column 21, a strip-shaped through hole 23 is provided on one side of the sleeve 22, and a diffuse reflection photoelectric sensor 3 is installed at the top end of the lifting column 21. The hole wall of the strip-shaped through hole 23 is slidably sleeved on the outside of the threaded rod 25, one end of the threaded rod 25 is fixedly connected to one side of the lifting column 21, and the outer part of the threaded rod 25 is threadedly connected to the inner ring of the nut sleeve 24.

[0031] Further, loosen the nut sleeve 24, push the nut sleeve 24 up and down. The nut sleeve 24 drives the lifting column 21 to move up and down through the threaded rod 25. The lifting column 21 drives the diffuse reflection photoelectric sensor 3 to move up and down, realizing the change of the height of the diffuse reflection photoelectric sensor 3 to meet the bottles of different heights. After the height is adjusted, tighten the nut sleeve 24 so that the lifting column 21 cannot move up and down.

[0032] Working principle: When in use, start the conveyor belt 5. The conveyor belt 5 drives the bottles to move. The bottles are located between the first limiting plate 11 and the second limiting plate 112 to prevent the bottles from falling off the conveyor belt 5. When the bottles pass through the diffuse reflection photoelectric sensor 3, the diffuse reflection photoelectric sensor 3 detects that the bottles have passed and transmits the signal to the opposed photoelectric sensor 4. The opposed photoelectric sensor 4 detects whether the bottles have contents and transmits the detection result to the actuator 1. The actuator 1 judges whether to alarm and reject or let pass through according to the received signal.

[0033] When the actuator 1 receives the signal to reject the empty bottles, the output shaft of the cylinder 18 extends and pushes the push plate 16 to move towards the baffle 12. At the same time, the push plate 16 also pushes the empty bottles to move towards the baffle 12. The push plate 16 pushes the baffle 12 to open through the connecting rod 14, making a notch appear in the first limiting plate 11. In this way, the empty bottles will be pushed away from the conveyor belt 5 through the notch, thus completing the rejection of the empty bottles.

[0034] When the push plate 16 moves towards the baffle 12, it drives the limiting block 19 to move towards the fixed plate 17 through the guide rod 111, causing the limiting block 19 to compress the return spring 110. When the output shaft of the cylinder 18 retracts, the return spring 110 will rebound and push the limiting block 19 away from the fixed plate 17. The limiting block 19 drives the push plate 16 to move towards the fixed plate 17 and return to the original position through the guide rod 111. The push plate 16 drives the baffle 12 to return to the original position through the connecting rod 14 to ensure the normal passage of the bottles on the conveyor belt 5. Through the combined use of the above structure, the rejection of empty bottles does not require manual intervention, the rejection rate is higher, and the cost and omission risk are reduced.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
