[0025] Reference Figs. 1-3 The pop-up cover 200 is sent to the capping machine by the conveying channel 100, so that the capping machine performs capping operation on the pop-up can body through the pop-up cover 200.

[0026] Among them, one end of the conveying channel 100 is connected to the cover supply end of the capping machine, and the bottom of the conveying channel 100 is provided with a conveying groove 120, and a plurality of pop-up covers 200 are placed in the conveying groove 120 in a stacked manner.

[0027] The reverse cap detection and rejection device comprises a reverse cap sensor 300, a telescopic cylinder 400 and a controller installed on the conveying channel 100. The reverse cap sensor 300 is a metal proximity switch. The sensing end of the reverse cap sensor 300 faces the side of the pop can 200 on the conveying channel 100. Since the two sides of the pop can 200 are not symmetrical, when the pop can 200 appears in a reverse cap state, a gap exists between the pop can 200 in the reverse cap state and the pop can 200 adjacent to one side thereof. When the gap passes through the reverse cap sensor 300, the reverse cap sensor 300 can detect the gap and generate a reverse cap signal.

[0028] In the embodiment, the installation position of the telescopic cylinder 400 is downstream of the installation position of the reverse cap sensor 300 with respect to the conveying channel 100, i.e., the pop can 200 passes through the position corresponding to the reverse cap sensor 300 first and then passes through the position corresponding to the telescopic cylinder 400 on the conveying channel 100.

[0029] The telescopic working direction of the telescopic cylinder 400 is perpendicular to the conveying direction of the pop can 200 in the conveying channel 100. The output end of the telescopic cylinder 400 is provided with a rejection plate 410.

[0030] Specifically, the side of the rejection plate 410 facing the pop can 200 is used to push the pop can 200 and is provided in a circular arc shape matching the outer circumferential side of the pop can 200. First edges 411 are formed on both sides of the side of the rejection plate 410 facing the pop can 200. The first edges 411 are triangular in cross section and have one end facing the pop can 200, and the first edges 411 are integrally formed with the rejection plate 410. In addition, a silica gel sleeve matching the end of the rejection plate 410 close to the pop can 200 is sleeved on the end, so that damage to the pop can 200 can be prevented when the pop can 200 is pushed. A notch 110 is provided on the side of the conveying channel 100 away from the telescopic cylinder 400. The notch 110 is in communication with the conveying groove 120, so that the notch 110 can be used to push the pop can 200 away from the conveying groove 120 from one side.

[0031] The controller is in communication connection with the conveying channel 100, the reverse cap sensor 300 and the telescopic cylinder 400, respectively.

[0032] The controller can obtain the conveying speed of the pop can 200 in the conveying channel 100. For example, a speed sensor is arranged to detect the conveying speed of the pop can 200 and transmit the conveying speed to the controller. The conveying distance between the reverse cap sensor 300 and the rejection plate 410 is measured and input into the controller. At the same time, the controller also receives the reverse cap signal sent by the reverse cap sensor 300.

[0033] It can be understood that when the controller receives the reverse cover signal sent by the reverse cover sensor 300, it means that the pull-tab cap 200 in the reverse cover state appears in the position corresponding to the reverse cover sensor 300 of the conveying channel 100. At this time, the controller calculates according to the received reverse cover signal, conveying distance and conveying speed, and generates a control signal containing execution time information and the like.

[0034] When the telescopic cylinder 400 receives the control signal, the telescopic cylinder 400 is started at the execution time, and the telescopic cylinder 400 drives the ejection plate 410 to move, so that the first edges on both sides of the ejection plate 410 are respectively embedded in the positions on both sides of the pull-tab cap 200 in the reverse cover state, and under the continuous pushing, the pull-tab cap 200 in the reverse cover state is pushed out of the position of the gap 110 from the conveying channel 100, and the pull-tab cap 200 in the reverse cover state is ejected. Thus, it can reduce the need to stop and manually remove the pull-tab cap 200 in the reverse cover state, improve production efficiency. At the same time, it can also prevent the situation that the fingers of the person are injured when manually removing the pull-tab cap 200, and improve safety.

[0035] It can be understood that the execution time refers to the time when the pull-tab cap 200 in the reverse cover state just reaches or is about to reach the position corresponding to the ejection plate 410 according to the calculation of the conveying speed and the distance. The telescopic cylinder 400 can be a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder.

[0036] Further, a second edge 412 is arranged on the side of the ejection plate 410 away from the first edge 411, the cross section of the second edge 412 is triangular, and one end of the second edge 412 in the initial state faces away from the pull-tab cap 200. The second edge 412 is integrally formed with the ejection plate 410, and the second edge 412 is in the middle position. After the telescopic cylinder 400 drives the ejection plate 410 to eject the pull-tab cap 200 in the reverse cover state, the ejection plate 410 can easily pass between the adjacent two pull-tab caps 200 on the conveying channel 100 through the second edge 412, so as to ensure that the ejection plate 410 can return to the initial position smoothly.

[0037] It can be understood that the telescopic cylinder 400 is fixed on one side of the conveying channel 100 through the mounting frame, and the output end of the telescopic cylinder 400 is higher than the highest position of the pull-tab cap 200 in the conveying process, so that the telescopic cylinder 400 does not hinder the normal conveying process of the pull-tab cap 200 when pushing the ejection plate 410.

[0038] Further, a protrusion 111 is arranged on the side bottom wall of the gap 110 close to the conveying groove 120, the height of the protrusion 111 is low, the protrusion 111 can limit the zip-top lid 200, so as to reduce the influence of the gap 110 on the conveying of the zip-top lid 200, thereby improving the conveying stability of the zip-top lid 200. In addition, the knockout plate 410 can also smoothly push the zip-top lid 200 in the reverse cover state to cross the protrusion 111 and separate from the conveying groove 120 from the gap 110.

[0039] The width of the side of the knockout plate 410 close to the zip-top lid 200 is the knockout distance between the two first edges 411, and the knockout distance is greater than the width occupied by the zip-top lid 200 in the reverse cover state. That is, when the knockout plate 410 pushes the zip-top lid 200 in the reverse cover state, it can knockout the adjacent zip-top lid 200 in the normal direction state together, thereby improving the reliability of knocking out the zip-top lid 200 in the reverse cover state.

[0040] A bracket 500 and a second bolt 540 are installed on the output end of the telescopic cylinder 400, and the bracket 500 is detachably installed on the output end of the telescopic cylinder 400 through the second bolt 540. A first bolt 530 is installed on the bracket 500, and the knockout plate 410 is detachably installed on the bracket 500 through the first bolt 530, so that different knockout widths of the knockout plate 410 can be replaced, thereby improving the flexibility and adaptability of the device. In other embodiments, the bracket 500 can be welded on the output end of the telescopic cylinder 400, and the knockout plate 410 can also be welded or bonded on the bracket 500.

[0041] A turnover box is installed on one side of the conveying channel 100, the opening of the turnover box is on the side away from the conveying groove 120 of the gap 110, or the bottom of the gap 110 is provided with a zip-top lid 200 falling channel connected to the top of the turnover box, so that the knockout zip-top lid 200 can fall and be collected into the turnover box, thereby facilitating the recycling of the knockout zip-top lid 200.

[0042] A motor 510 is installed on the bracket 500, and a connecting rod is rotatably installed on the bracket 500, the connecting rod is provided with a filling block 520, the width of the filling block 520 is matched with the width of the gap 110, so that the filling block 520 can just fill the gap 110, so that the zip-top lid 200 cannot be removed from the gap 110 temporarily. The end of the filling block 520 close to the knockout plate 410 is arranged in a circular arc type matched with the outer circumference of the zip-top lid 200.

[0043] The output end of the motor 510 is connected to the connecting rod, so that the motor can drive the connecting rod and the filling block 520 to rotate together. The motor 510 is in communication connection with the telescopic cylinder 400. When the telescopic cylinder 400 drives the ejecting plate 410 to start pushing the zip-top lid 200, the motor synchronously drives the filling block 520 to rotate in a direction away from the ejecting plate 410. When the zip-top lid 200 is completely pushed out of the conveying groove 120, the zip-top lid 200 can fall into the turnover box through the gap 110. When the telescopic cylinder 400 returns to the initial position, the motor also drives the filling block 520 to rotate back to the initial angular position.

[0044] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
