[0030] Example 1:

[0031] Please refer to Figure 1-4 This embodiment provides a cap selection mechanism, including a conveying assembly 10, a cap discharging assembly 20, a rejecting assembly 30 and a control system;

[0032] The conveyor assembly 10 includes a conveyor mounting frame 11, which is made of several metal profiles and plates and mainly provides an installation and support foundation for the various components of the conveyor assembly 10. The conveyor mounting frame 11 is installed with a conveyor drive member 12, a synchronous belt assembly 13 and a second encoder 14; the synchronous belt assembly 13 is sequentially formed with an input station 131, a rejection station 132 and an output station 133; the conveyor drive member 12 is connected to the synchronous belt assembly 13, and is powered by the conveyor drive member 12. The bottle caps are driven by the synchronous belt assembly 13 to pass through the input station 131, the rejection station 132 and the output station 133 in sequence; the second encoder 14 is used to calculate the transportation distance of the synchronous belt assembly 13;

[0033] The cap discharging assembly 20 includes a cap discharging fixing frame 21, which is fixedly connected to the conveying mounting frame 11; a chuck conveying device 22 and a first encoder 23 are installed on the cap discharging fixing frame 21, and the chuck conveying device 22 has a cap receiving position 221 and a cap discharging position 222, and the chuck conveying device 22 can transport the bottle cap from the cap receiving position 221 to the cap discharging position 222; the cap receiving position 221 is used to receive the bottle cap separated from the mold; the cap discharging position 222 coincides with the input station 131 of the conveying assembly 10, thereby connecting the assembly 20 with the conveying assembly 10; the first encoder 23 is connected to the chuck conveying device 22, and the first encoder 23 is used to calculate the moment when the target bottle cap separated from the target mold arrives at the cap discharging position 222;

[0034] The rejecting assembly 30 is disposed near the rejecting station 132 , and is used to reject the bottle caps on the rejecting station 132 .

[0035] The control system is electrically connected to the rejection component 30, the first encoder 23, and the second encoder 14 respectively. The control system obtains rejection information by analyzing and processing the recorded information of the first encoder 23 and the second encoder 14, and controls the rejection component 30 to execute the rejection instruction according to the rejection information.

[0036] Based on the above structure, when in use, the bottle cap is formed from the turntable of the compression molding capping machine, and the cap receiving position 221 is used to receive the bottle cap separated from the mold, and the bottle cap is transported from the cap receiving position 221 to the cap discharging position 222 by the chuck conveying device 22; since the cap receiving position 221 corresponds to the mold one by one, when it is necessary to select a bottle cap of a target mold number, the position of the corresponding target cap receiving position 221 is recorded by the first encoder 23, and the position of the target bottle cap corresponding to the target mold can be located. Since the angle from the cap receiving position 221 to the cap discharging position 222 is fixed, the time when the target bottle cap reaches the cap discharging position 222 can be calculated by the recorded data of the first encoder 23; since the cap discharging position 222 coincides with the input station 131, this moment is the time when the target bottle cap enters the input station 131. At the moment when the conveying component 10 reaches the input station 131, the synchronous belt component 13 drives the target bottle cap to move; the second encoder 14 calculates the transportation distance of the target bottle cap on the synchronous belt component 13 after it arrives at the input station 131; when the transportation distance of the target bottle cap on the synchronous belt component 13 reaches a preset distance, the rejection component 30 extends to reject the bottle cap; the preset distance is the distance from the input station 131 to the rejection station 132. When the transportation distance recorded by the second encoder 14 reaches the preset distance, it means that the target bottle cap has moved from the input station 131 to the rejection station 132. At this time, the rejection component 30 performs the rejection action to accurately reject the target bottle cap. This reciprocating process can achieve the goal of selecting all bottle caps of a specific model number.

[0037] This embodiment provides a first encoder 23 and a second encoder 14. When a target bottle cap arrives at the input station 131 from the cap discharging assembly, the first encoder 23 records the target bottle cap's position. At this time, the second encoder 14 records the transport distance of the synchronous belt assembly 13. Since the distance from the input station 131 to the rejection station 132 is fixed, the target bottle cap's position on the synchronous belt assembly 13 can be accurately determined. Therefore, when the target bottle cap arrives at the rejection station 132, the rejection assembly 30 receives a signal and rejects the target bottle cap. This upgrades the original manual cap selection method to automatic selection, greatly improving production efficiency and the degree of automation of the equipment. Compared to other visual recognition rejection methods, this embodiment does not require complex recognition operations, has a fast response, and can effectively avoid visual recognition errors, reducing the risk of misselection or omission. It is more adaptable to situations where the equipment has many models and high demand, and can efficiently select bottle caps of specific models.

[0038] Specifically, the chuck conveying device 22 includes a first cap ejecting chuck 223 and a second cap ejecting chuck 225, both of which are disc-shaped parts with a plurality of grooves formed circumferentially, and the bottle caps stuck in the grooves are transported by rotating the first cap ejecting chuck 223 and the second cap ejecting chuck 225; a first cap ejecting channel 224 is formed circumferentially on the first cap ejecting chuck 223, and the first cap ejecting channel 224 has an input end and an output end; a second cap ejecting channel 226 is formed circumferentially on the second cap ejecting chuck 225, and the second cap ejecting channel 226 has an output end; the input end of the first cap ejecting chuck 223 is connected to the output end of the second cap ejecting chuck 225; the cap ejecting position 222 is formed at the output end of the first cap ejecting channel 224, and a plurality of the cap connecting positions 221 are formed circumferentially on the second cap ejecting chuck 225. That is, the first cap discharging channel 224 is connected to the second cap discharging channel 226 to form a complete bottle cap transportation channel, which transports the bottle caps received by the cap receiving position 221 to the cap discharging position 222 in sequence.

[0039] The chuck conveying device 22 has a cap discharging transmission shaft 227 and a cap discharging driving member, and the cap discharging driving member is connected to the second cap discharging chuck 225 through the cap discharging transmission shaft 227, and is powered by the cap discharging driving member, and drives the second cap discharging chuck 225 to rotate through the cap discharging transmission shaft 227; the first encoder 23 is connected to the cap discharging transmission shaft 227, and the first encoder 23 is a rotary encoder, which records the angular displacement of the cap discharging rotation axis through the first encoder 23 to calculate the moment when the target bottle cap reaches the cap discharging position 222.

[0040] The synchronous belt assembly 13 of this embodiment includes a first conveyor roller 134, a second conveyor roller 135, an active roller 136 and a conveyor belt 137; the first conveyor roller 134 and the second conveyor roller 135 are respectively connected to the opposite ends of the conveyor mounting frame 11 through sliding bearing seats, the active roller 136 is rotatably connected to the bottom of the conveyor mounting frame 11 through a fixed plate, and the conveyor belt 137 is circumferentially wound around the active roller 136, the first conveyor roller 134 and the second conveyor roller 135.

[0041] The timing belt assembly 13 further includes a first tensioning roller 138 and a second tensioning roller 139, which are respectively disposed on opposite sides of the driving roller 136. The first tensioning roller 138 and the second tensioning roller 139 increase the wrap angle between the driving roller 136 and the conveyor belt 137, thereby preventing slippage and improving positioning accuracy.

[0042] The conveying drive member 12 has an output shaft connected to the driving roller 136 via a speed reducer. The second encoder 14 is connected to the driving roller 136. The second encoder 14 is a rotary encoder that records the angular displacement of the driving roller 136 and the diameter of the driving roller 136 to calculate the transport distance of the synchronous belt assembly 13.

[0043] The rejection assembly 30 of this embodiment includes a rejection mounting plate 31, which is fixedly connected to the conveyor mounting frame 11. A blow shaft 32 and a control valve 33 are mounted on the rejection mounting plate 31. The control valve 33 of this embodiment is a solenoid-controlled valve. An air inlet and a blow port are formed at each end of the blow shaft 32, respectively. The air inlet is connected to the control valve 33 via an air pipe. The control valve 33 is connected to an air supply device, and the solenoid-controlled valve controls the opening and closing of the air supply channel between the blow shaft 32 and the air supply device. The blow port is located on one side of the rejection station 132. When the solenoid-controlled valve receives a pulse signal from the control system, it briefly opens the air supply channel connecting the blow shaft 32, causing the blow port to blow out a high-pressure airflow, which removes the target bottle caps from the rejection station 132. This is highly efficient and does not affect the normal passage of subsequent bottle caps through the rejection station 132. It can effectively select bottle caps of a specific mold number when the equipment has a large number of mold numbers and a high demand.

[0044] Furthermore, the rejection component 30 also includes a cap recovery component 34, which is fixed to the conveying mounting frame 11; a cap slide is formed inside the cap recovery component 34, and a slide inlet and a slide outlet are formed at both ends of the cap slide respectively, and the slide inlet is arranged opposite to the blowing port of the blowing shaft 32, and the slide outlet is used to collect the rejected bottle caps to a collection area.

[0046] Finally, it should be noted that the above-mentioned implementation mode is only a preferred embodiment mode of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
