DETAILED DESCRIPTION

[0063] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0065] like Figure 1 As shown, in one embodiment of the container cap collecting device 200 provided by the present invention, the collecting device includes a cap removing device 60, a receiving device 30, a cap removing device 40 and a first conveying device 50. The cap removing device 60 is used to remove the container cap 20 from the container 10 at the first station. The receiving device 30 is used to receive the container cap 20 removed by the cap removing device 60 at the first station, and the receiving device 30 can move relative to the first station. The cap removing device 40 is used to remove the container cap 20 from the receiving device 30. The first conveying device 50 is arranged on one side of the cap removing device 60. The first conveying device 50 is used to receive the container cap 20 removed by the cap removing device 40 and convey the container cap 20.

[0066] In the above embodiment, the container cap 20 is removed from the container 10 at the first station by the cap removal device 60, and then the container cap 20 removed by the cap removal device 60 is received by the receiving device 30, and then the receiving device 30 moves with the container cap 20 relative to the first station to leave the first station, and the container cap 20 can be removed from the receiving device 30 by the cap removal device 40, and the removed container cap 20 is received and transported by the first conveying device 50. The removal, transportation and collection of the container cap 20 are realized by the cap removal device 60, the receiving device 30, the cap removal device 40 and the first conveying device 50, which can greatly save costs compared with the solution using a mechanical arm.

[0067] After the capping device 60 completes the capping work at the first station, the receiving device 30 receives the container cap 20 and carries it for movement. Therefore, the capping device 60 does not need to leave the first station, which can save the time of its reciprocating movement. The first conveying device 50 is located on one side of the capping device 60. Therefore, the operation of the first conveying device 50 receiving and conveying the container cap 20 is performed at a position outside the first station. In this way, the capping device 60 can be put into the next round of capping work after the receiving device 30 leaves. The interval time is short, which is conducive to improving the efficiency of capping.

[0068] Furthermore, the cover-pushing device 40 is configured to realize the removal of the container cover 20 from the receiving device 30 by relative movement with the receiving device 30. Compared with the solution of picking up, moving, and then putting down the container cover 20, this transfer method of realizing the removal of the container cover 20 from the receiving device 30 by relative movement of the cover-pushing device 40 and the receiving device 30 has a simpler movement method and a simpler structure. Moreover, a larger number of container covers 20 can be removed at one time, and the operation is more direct, fast, effective, and efficient.

[0069] Specifically, when the container cover 20 is removed, the receiving device 30 can be kept stationary and the cover-moving device 40 can move relative to the receiving device 30; or, the cover-moving device 40 can be kept stationary and the receiving device 30 can move relative to the cover-moving device 40; or, both the receiving device 30 and the cover-moving device 40 move relative to the ground, but at different speeds or directions, that is, the receiving device 30 and the cover-moving device 40 have relative movement.

[0070] In such Figures 2 to 10 In the embodiment shown, a solution is adopted in which the cover-pushing device 40 remains stationary while the receiving device 30 moves relative to the cover-pushing device 40. Therefore, the receiving device 30 can move relative to the first station. Keeping the cover-pushing device 40 stationary can save the driving components for moving the cover-pushing device 40, thereby saving investment costs. At the same time, reducing the number of moving parts can also reduce maintenance costs.

[0071] Optionally, the cover-pushing device 40 realizes the function of removing the container cover 20 during the process of the receiving device 30 returning to the first workstation. In this way, the movement of the receiving device 30 can be fully utilized. The cover-pushing function can be completed while the receiving device 30 completes its function. This can save time and improve work efficiency, save parts and reduce costs.

[0072] The specific structure of the cover-pushing device 40 can be selected in many ways, such as a stopper bar or a steel wire rope, etc. The stopper bar or the steel wire rope can be used to pull off multiple container covers 20 at one time, and failure of pulling off can be avoided, thereby improving the success rate of pulling off.

[0073] The cover-pushing device 40 can be arranged to be liftable relative to the receiving device 30. The advantage of such arrangement is that when the cover-pushing device 40 is needed to be used for cover-pushing, the cover-pushing device 40 can be lowered to a height higher than the receiving device 30 and lower than the container cover 20 on the receiving device 30, so that when the receiving device 30 moves relative to the cover-pushing device 40, the container cover 20 can be pushed off from the receiving device 30 by utilizing the blocking effect of the cover-pushing device 40 on the container cover 20; and when the cover-pushing device 40 is not needed for cover-pushing, for example, before the receiving device 30 moves to the cover-pushing position, the cover-pushing device 40 can be raised to a height higher than the container cover 20 on the receiving device 30, so as to avoid interference of the cover-pushing device 40 with the movement of the receiving device 30, and it can also be helpful to enable the receiving device 30 to move to a suitable position before the cover is pulled.

[0074] By arranging the cover-opening device 40 to be liftable relative to the receiving device 30, the movement route of the receiving device 30 can be shortened, so that the receiving device 30 does not need to take a detour to avoid interference with the cover-opening device 40 before reaching a suitable cover-opening position, which is beneficial to reducing the space required for the entire device and also can improve efficiency.

[0075] When the receiving device 30 is at the first station, the receiving device 30 is located below (for example, directly below) the cap removing device 60, so that the cap removing device 60 can make the container cap 20 fall directly onto the receiving device 30 after releasing the container cap 20, so as to facilitate the receiving device 30 to receive it. After receiving the container cap 20, the receiving device 30 will move with the container cap 20 relative to the first station to leave the first station, so as to facilitate the cap removing device 60 to continue the next round of cap removing operation.

[0076] After the receiving device 30 leaves the first station, when the cap removing device 40 is used to remove the cap, the receiving device 30 is located above the first conveying device 50. Specifically, before the cap removal begins, the receiving device 30 is located directly above the first conveying device 50. When the cap is removed, the receiving device 30 moves to one side relative to the first conveying device 50, and the receiving device 30 gradually moves away from directly above the first conveying device 50 until the receiving device 30 returns to the first station, and the receiving device 30 is located obliquely above the first conveying device 50. In this way, the cap removal can be realized conveniently by using the process of the receiving device 30 returning to the first station, and the first conveying device 50 can receive the removed container cap 20 conveniently.

[0077] The receiving device 30 includes a receiving platform, and the container cover 20 is detached from the receiving platform from a first side of the receiving platform, and at least one side of the receiving platform adjacent to or opposite to the first side is provided with a boss 31 for preventing the container cover 20 from falling off. By providing the boss 31, the container cover 20 can be prevented from falling off from a position other than the first side.

[0078] The cap removal device 60 may include a cap screwing ring 61 and a rotating shaft 62, wherein the rotating shaft 62 is connected to the cap screwing ring 61, a through hole is provided at the center of the cap screwing ring 61, and the cap screwing ring 61 is used to be sleeved on the outer periphery of the container cap 20 and to screw the container cap 20 off the container 10 under the rotation of the rotating shaft 62. The inner wall of the cap screwing ring 61 contacts the outer periphery of the container cap 20, and when the rotating shaft 62 drives the cap screwing ring 61 to rotate, the cap screwing ring 61 screws off the container cap 20 by relying on the friction between the cap screwing ring 61 and the container cap 20.

[0079] The inner diameter of the screw cap ring 61 can be set to gradually decrease from the end surface inward, that is, the inner wall of the screw cap ring 61 is an inclined surface, or the diameter of the through hole gradually decreases from the end surface inward. This setting can facilitate the container cover 20 to enter the interior of the screw cap ring 61 and clamp the container cover 20 by utilizing the change in the diameter of the through hole.

[0080] The cap removal device 60 further comprises a disengaging device, which is used to disengage the container cap 20 from the cap screwing ring 61 .

[0081] The disengagement device includes a retaining ring 63, the diameter of which is larger than the diameter of the cover screwing ring 61, and the cover screwing ring 61 and the rotating shaft 62 can move relative to each other with the retaining ring 63, and the retaining ring 63 is used to separate the container cover 20 from the cover screwing ring 61 when the retaining ring 63 moves relative to the cover screwing ring 61 and the rotating shaft 62. By providing the retaining ring 63, the container cover 20 can be easily separated from the cover screwing ring 61.

[0082] Specifically, when the container cover 20 is separated from the cover screwing ring 61, the cover screwing ring 61 and the rotating shaft 62 can be kept stationary, and the retaining ring 63 moves relative to the cover screwing ring 61 and the rotating shaft 62; or, the retaining ring 63 can be kept stationary, and the cover screwing ring 61 and the rotating shaft 62 move relative to the retaining ring 63; or, the cover screwing ring 61, the rotating shaft 62 and the retaining ring 63 all move relative to the ground, but the movement speeds or directions are different, and there is relative movement between the cover screwing ring 61 and the rotating shaft 62 and the retaining ring 63.

[0083] The relative motion between the cover screwing ring 61, the rotating shaft 62 and the retaining ring 63 can be in the form of linear motion or curved motion. For example, linear relative motion can occur in the vertical direction. The container cover 20 is provided with a flange. When relative motion occurs between the cover screwing ring 61, the rotating shaft 62 and the retaining ring 63, the retaining ring 63 can push the flange to move, thereby pushing the container cover 20 away from the cover screwing ring 61.

[0084] The container cap collecting device 200 may include a plurality of cap removing devices 60 and a receiving device 30, wherein the plurality of cap removing devices 60 are arranged side by side and operate synchronously, and the receiving device 30 is used to simultaneously receive a plurality of container caps 20 removed by the plurality of cap removing devices 60. In this way, without increasing the receiving device 30 and the first conveying device 50, a plurality of cap removing devices 60 may be arranged simultaneously, thereby greatly improving the cap removing efficiency.

[0085] Combine the following Figure 1 The specific structure of an embodiment of the container cap collecting device 200 of the present invention is described as follows:

[0086] like Figure 1 As shown, the container cap collecting device 200 includes a cap unloading device 60, a receiving device 30, a cap removing device 40 and a first conveying device 50, wherein the cap unloading device 60 includes a cap screwing ring 61, a rotating shaft 62 and a retaining ring 63. The cap screwing ring 61, the rotating shaft 62 and the retaining ring 63 are coaxially arranged, and the outer diameter of the cap screwing ring 61 is smaller than the inner diameter of the retaining ring 63. A through hole is provided at the center of the retaining ring 63, and the cap screwing ring 61 and the rotating shaft 62 are arranged in the through hole of the retaining ring 63. The retaining ring 63 is fixedly arranged relative to the ground, and the cap screwing ring 61 is fixedly connected to the rotating shaft 62. The rotating shaft 62 is driven by the first driving mechanism so that the rotating shaft 62 rotates around its own axis and drives the cap screwing ring 61 to rotate. The cap screwing ring 61 and the rotating shaft 62 can move up and down relative to the retaining ring 63, and specifically, the rotating shaft 62 can be driven up and down by the second driving mechanism to drive the cap screwing ring 61 to move up and down together.

[0087] The hole wall of the central through hole of the screw cap ring 61 includes a variable diameter section and a constant diameter section. The lower half of the hole wall is a variable diameter section with a gradually decreasing opening from bottom to top, and the upper half is a constant diameter section with equal diameter.

[0088] The diameter of the upper portion of the container cover 20 gradually increases from top to bottom, and the lower portion of the container cover 20 is a flange with a diameter larger than that of the upper portion. The diameter of the flange is larger than the outer diameter of the retaining ring 63.

[0089] The receiving device 30 can be driven by the third driving mechanism so that the receiving device 30 moves translationally relative to the first station.

[0090] The cover removal device 60 completes the work of removing the container cover 20 at the first station. When the receiving device 30 moves to the first station, the cover removal device 60 is located directly above the receiving device 30, and the container 10 with the container cover 20 removed is located directly below the receiving device 30.

[0091] The cover removing device 40 includes a cross bar, which is arranged along the conveying direction of the first conveying device 50. The connecting line of the cross bar and the plurality of cover removing devices 60 is parallel to each other.

[0092] The cover-moving device 40 can move up and down relative to the first conveying device 50 , and can be specifically driven by the fourth driving mechanism.

[0093] The capping device 40 and the first conveying device 50 are both arranged on the right side of the cap removing device 60. The first conveying device 50 is fixed relative to the ground. The first conveying device 50 can be a belt conveyor or a chain conveyor. After receiving the container cap 20, the first conveying device 50 conveys the container cap 20 to a storage bin for storing the container cap 20 or conveys it to the next process line for further operation on the container cap 20.

[0094] The position of the first conveying device 50 is called the second station. When the receiving device 30 moves to the second station, the receiving device 30 is located directly above the first conveying device 50, and the cover removing device 40 is located above the receiving device 30 and on the side of the first conveying device 50 close to the cover removing device 60.

[0095] The first station and the second station are two virtual stations parallel to the horizontal plane, and the first station is located on the left side of the second station. The distance between the first station and the second station can be shortened as much as possible according to actual conditions to make the overall layout more compact and save space.

[0096] The first drive mechanism, the second drive mechanism, the third drive mechanism and the fourth drive mechanism can be oil cylinders, air cylinders or motors, etc. The first drive mechanism, the second drive mechanism, the third drive mechanism and the fourth drive mechanism can be provided separately or integrated together.

[0097] The container cap collecting device 200 may further include a controller, which is used to control the actions of the cap removing device 60 , the receiving device 30 , the cap removing device 40 and the first conveying device 50 .

[0098] Combine the following Figures 2 to 10 The working process of one embodiment of the container cap collecting device 200 of the present invention is described as follows:

[0099] like Figure 2 As shown, the receiving device 30 moves from left to right to the top of the first conveying device 50, at which time the cover screwing ring 61 and the rotating shaft 62 are in a retracted state, the cover screwing ring 61 and the rotating shaft 62 are retracted into the retaining ring 63, and the cover removing device 40 is in a raised state;

[0100] like Figure 3 As shown, the cover screwing ring 61 and the rotating shaft 62 extend downward relative to the retaining ring 63 until the cover screwing ring 61 covers the container cover 20 on the container 10 located below the cover removal device 60, and the first driving mechanism drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the cover screwing ring 61 to rotate, and the cover screwing ring 61 removes the container cover 20 from the container 10 by friction.

[0101] like Figure 4As shown, the retaining ring 63 remains stationary, the cover screwing ring 61 and the rotating shaft 62 retract upward relative to the retaining ring 63, and drive the container cover 20 to rise together, until the cover screwing ring 61 and the rotating shaft 62 drive the container cover 20 to rise to a position close to the retaining ring 63;

[0102] like Figure 5 As shown, the receiving device 30 returns from right to left to the position directly below the cover removal device 60;

[0103] like Figure 6 As shown, the cover screwing ring 61 and the rotating shaft 62 continue to move upward, and the retaining ring 63 contacts the lower flange of the container cover 20. Under the blocking effect of the retaining ring 63, the container cover 20 is separated from the cover screwing ring 61 and falls onto the receiving device 30;

[0104] like Figure 7 As shown, after receiving the container cover 20, the receiving device 30 drives the container cover 20 to move rightward to just above the first conveying device 50;

[0105] like Figure 8 As shown, the cover-pushing device 40 moves downward to a height higher than the receiving device 30 and lower than the container cover 20 on the receiving device 30;

[0106] like Fig. 9 As shown, the receiving device 30 moves leftward and returns to the position directly below the cap removing device 60. During the return process, the container cap 20 is removed from the receiving device 30 by the blocking action of the cap removing device 40 and falls onto the first conveying device 50, and is conveyed to a preset position by the first conveying device 50.

[0107] like Fig.10 As shown, after all the container caps 20 on the receiving device 30 have fallen onto the first conveying device 50, the cap removing device 40 rises, and the process of unloading, receiving, removing and delivering caps is completed. Then, the receiving device 30 can continue to move rightward to the top of the first conveying device 50, thereby starting the next round of container cap collection process.

[0108] The present invention further provides a container cap collection system, which includes the container cap collection device 200 described above.

[0109] like Fig.11As shown, the container cap collection system includes a second conveying device 100, a container cap collection device 200, a first rejection device 300 and a third conveying device 400, wherein the second conveying device 100 is used to convey containers 10, the container cap collection device 200 is used to remove and collect container caps 20 on the containers 10 conveyed by the second conveying device 100, the first rejection device 300 is arranged downstream of the container cap collection device 200, and the first rejection device 300 is used to reject containers 10 whose container caps 20 have not been removed after detection from the second conveying device 100, and the third conveying device 400 is connected to the starting end of the second conveying device 100 and is located upstream of the container cap collection device 200, and the third conveying device 400 is used to convey the containers 10 rejected by the first rejection device 300 to the second conveying device 100. The third conveying device 400 and the second conveying device 100 form a closed-loop conveying.

[0110] In the above embodiment, the container cap collection system includes a first rejection device 300 and a third conveying device 400. When the containers 10 on the second conveying device 100 are not successfully removed from the container caps 20 by the container cap collecting device 200, the first rejection device 300 will reject these containers 10 from the second conveying device 100, and these rejected containers 10 can be sent back to the second conveying device 100 via the third conveying device 400. The third conveying device 400 is connected to the starting end of the second conveying device 100 and is located upstream of the container cap collecting device 200. Therefore, the containers 10 sent back to the second conveying device 100 via the third conveying device 400 can pass through the container cap collecting device 200 again for a second opening. In this way, the containers 10 that were not successfully opened for the first time can be reprocessed, reducing or even eliminating the configuration of opening personnel and saving labor costs; the containers 10 that were not successfully opened can also be processed in a timely manner to avoid backlogs and affect product quality.

[0111] The container cap collection system further includes a first detection device 500, which is disposed downstream of the container cap collection device 200 and upstream of the first rejection device 300, and is used to detect whether the container cap 20 is removed. By providing the first detection device 500, it is possible to automatically detect whether the container cap 20 is removed, thereby improving the automation of the container cap collection system and reducing manpower input.

[0112] The third conveying device 400 is provided with a first blocking device 600, and the first blocking device 600 is used to block the container 10 from entering the second conveying device 100. By providing the first blocking device 600, it is possible to control whether the third conveying device 400 is connected to the second conveying device 100, so as to prevent the container 10 transported by the third conveying device 400 to the second conveying device 100 from colliding with the container 10 transported by the second conveying device 100. When the first blocking device 600 is opened, the third conveying device 400 and the second conveying device 100 are blocked by the first blocking device 600 and are not connected, and the container 10 on the third conveying device 400 cannot be transported to the second conveying device 100. When the first blocking device 600 is closed, the third conveying device 400 is connected to the second conveying device 100, and the container 10 on the third conveying device 400 can be transported to the second conveying device 100.

[0113] The container cap collection system further includes a fourth conveying device 700, which is connected to the beginning of the second conveying device 100 and is used to convey the container 10 to the second conveying device 100. The fourth conveying device 700 is in communication with the second conveying device 100, and continuously conveys the container 10 to the second conveying device 100, so as to provide the second conveying device 10 with the container 10. The fourth conveying device 700 and the second conveying device 100 may be two independent conveying devices, or may be connected as one. When the fourth conveying device 700 and the second conveying device 100 are connected as one, the connection position between the fourth conveying device 700 and the second conveying device 100 is the beginning of the second conveying device 100, and the third conveying device 400 is connected at the connection position between the fourth conveying device 700 and the second conveying device 100.

[0114] The fourth conveying device 700 is provided with a second blocking device 800, and the second blocking device 800 is used to block the container 10 on the fourth conveying device 700 from entering the second conveying device 100. By providing the second blocking device 800, it is possible to control whether the fourth conveying device 700 is connected to the second conveying device 100, so as to avoid collision between the container 10 transported to the second conveying device 100 by the fourth conveying device 700 and the container 10 transported to the second conveying device 100 by the third conveying device 400. When the second blocking device 800 is opened, the fourth conveying device 700 and the second conveying device 100 are blocked by the second blocking device 800 and are not connected, and the container 10 on the fourth conveying device 700 cannot be transported to the second conveying device 100. When the second blocking device 800 is closed, the fourth conveying device 700 is connected to the second conveying device 100, and the container 10 on the fourth conveying device 700 can be transported to the second conveying device 100.

[0115] The container cap collection system may further include a second detection device 900, which is disposed upstream of the first blocking device 600 and is signal-connected to the first blocking device 600 and the second blocking device 800. The second detection device 900 is used to send a signal to the first blocking device 600 and the second blocking device 800 when it detects that a container 10 passes through the third conveying device 400.

[0116] By setting up the second detection device 900, when it is detected that there is a container 10 on the third conveying device 400 that needs to be conveyed to the second conveying device 100, a signal can be sent to the first blocking device 600 and the second blocking device 800 to close the first blocking device 600 and open the second blocking device 800, so that the container 10 to be conveyed to the second conveying device 100 by the fourth conveying device 700 can stop entering the second conveying device 100, while the container 10 on the third conveying device 400 can enter the second conveying device 100, thereby avoiding collision of the containers 10 on the entire conveying line; and when there is no container 10 on the third conveying device 400 that needs to be conveyed to the second conveying device 100, the first blocking device 600 can be opened and the second blocking device 800 can be closed, so that the containers 10 on the fourth conveying device 700 can be continuously conveyed to the second conveying device 100.

[0117] The container cap collection system also includes a second rejection device 1000 and a collection platform 1100. The second rejection device 1000 is arranged downstream of the first rejection device 300. The second rejection device 1000 is used to reject containers 10 on the second conveying device 100 whose container caps 20 have not been removed after passing through the container cap collection device 200 at least twice. The collection platform 1100 is connected to the second conveying device 100 and is used to receive the containers 10 rejected by the second rejection device 1000.

[0118] Generally, after passing through the container cap collecting device 200 at least twice, the container caps 20 on most containers 10 will be successfully removed. If they are still unsuccessful, they can be identified as containers 10 that are difficult to remove the container caps 20. In this case, if they continue to be sent back to the second conveying device 100 and repeatedly pass through the container cap collecting device 200, not only is the possibility of the container caps 20 being removed small, but the efficiency of removing the caps from normal containers will also be reduced. Therefore, after the second rejection device 1000 and the collection platform 1100 are set, the containers 10 that have not been removed after at least two openings can be conveyed to the collection platform 1100 for unified collection. After collection, these containers 10 can be manually opened or directly discarded. Since the number of these containers 10 is small, the intensity of manual opening will not be too great, and more importantly, collecting these containers 10 can improve the efficiency of removing the caps from normal containers.

[0119] Combine the following Fig.11 The specific structure and working process of an embodiment of the container cap collection system of the present invention are described as follows:

[0120] like Fig.11 As shown, the container cap collection system includes a second conveying device 100, a container cap collecting device 200, a first rejection device 300 and a third conveying device 400. The second conveying device 100 passes through the container cap collecting device 200, the first rejection device 300 is arranged on one side of the second conveying device 100, and the third conveying device 400 is connected to the other side of the second conveying device 100 opposite to the first rejection device 300. The second conveying device 100 and the third conveying device 400 are connected to form a rectangular closed loop.

[0121] A plurality of containers 10 are placed on the second conveying device 100 , and the plurality of containers 10 may enter the container cap collecting device 200 in groups. The container cap collecting device 200 may be provided with a plurality of decapping stations to perform decapping operations on the plurality of containers 10 at the same time.

[0122] The container cap collection system further includes a fourth conveying device 700, which is connected to the second conveying device 100. The third conveying device 400 is directly connected to the second conveying device 100, and the fourth conveying device 700 is connected to the second conveying device 100 from the side of the second conveying device 100. The end of the fourth conveying device 700 connected to the second conveying device 100 is away from the side of the second conveying device 100 and gradually tilts toward the direction close to the second conveying device 100.

[0123] The container cap collection system further comprises a first detection device 500 disposed upstream of the first rejection device 300 and located at one side of the second conveying device 100. The container cap collection system further comprises a second detection device 900 disposed at one side of the third conveying device 400.

[0124] A first blocking device 600 is disposed at the end of the third conveying device 400, and a second blocking device 800 is disposed at the end of the fourth conveying device 700. A second rejecting device 1000 is disposed downstream of the first rejecting device 300, and the second rejecting device 1000 is disposed on one side of the second conveying device 100, and a collecting platform 1100 is disposed on the other side opposite to the second rejecting device 1000.

[0125] During operation, in the initial state, the first blocking device 600 is in an open state, the second blocking device 800 is in a closed state, the first rejecting device 300 is in an open state, and the second rejecting device 1000 is in a closed state. After the work starts, the container 10 on the fourth conveying device 700 is conveyed to the second conveying device 100, and the container cap 20 of the container 10 is removed when passing through the container cap collecting device 200; the container 10 whose container cap 20 is not successfully removed will be detected by the first detection device 500, and the signal will be transmitted to the first rejection device 300. The first rejection device 300 rejects it after receiving the signal from the first detection device 500, and the rejected container 10 enters the third conveying device 400; after the second detection device 900 detects the container 10, it sends a signal to the first blocking device 600 and the second blocking device 800 to open the second blocking device 800, and the container 10 on the fourth conveying device 700 stops entering the second conveying device 100, and the first blocking device 600 is closed, so that the container 10 on the third conveying device 400 enters the second conveying device 100, so that the container 10 whose container cap 20 is not successfully removed after passing through the container cap collecting device 200 for the first time can pass through the container cap collecting device 200 again for re-cap removal.

[0126] If the preset container 10 has not had its container cap 20 successfully removed after passing through the container cap collecting device 200 twice, it is determined that it is a container 10 from which the container cap 20 is difficult to remove. After the container 10 is conveyed to the second conveying device 100 via the third conveying device 400, the first rejection device 300 is closed and the second rejection device 1000 is opened. If this part of the container 10 has not been successfully removed after passing through the container cap collecting device 200 again after detection by the first detection device 500, it will be rejected by the second rejection device 1000 to the collection platform 1100 for manual removal of the cap or other processing.

[0127] If the preset container 10 has not had its container cap 20 successfully removed after passing through the container cap collecting device 200 for three times, it is determined that it is a container 10 from which the container cap 20 is difficult to remove. After the container 10 is conveyed to the second conveying device 100 by the third conveying device 400 for the second time, the first rejection device 300 is closed and the second rejection device 1000 is opened. After the first detection device 500 detects that the container 10 that has passed through the container cap collecting device 200 for the third time has not been successfully removed, it will be rejected by the second rejection device 1000 to the collection platform 1100 for manual cap removal or other processing.

[0128] If the preset container 10 has not had its container cap 20 successfully removed after passing through the container cap collecting device 200 for more than three times, it is determined that it is a container 10 from which the container cap 20 is difficult to remove. The opening time of the second rejection device 1000 can be extended accordingly, and it will not be opened until the number of times it has passed through the container cap collecting device 200 reaches the limit. This will not be elaborated here.
