[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] like Figure 1 and Figure 2As shown, this embodiment provides an automatic rejection device for burnt cigarette sticks. The automatic rejection device for burnt cigarette sticks includes a conveying device 100 and a flap 200. The conveying device 100 is used to convey cigarette sticks 1 along the conveying direction. The flap 200 is rotatably disposed on one side of the conveying device 100 along the conveying direction. The flap 200 has an automatic rejection working state and a normally open sampling working state. When the flap 200 is in the automatic rejection working state, the flap 200 can reject the cigarette sticks 1 on the conveying device 100. When the flap 200 is in the normally open sampling working state, the flap 200 can be opened relative to the conveying device 100 for a first preset time to reject the cigarette sticks 1 on the conveying device 100.
[0036] A conveying device 100 is provided to convey cigarette sticks 1 along the conveying direction; a flap 200 is provided by rotating the conveying device 100 to remove unqualified cigarette sticks 1 from the conveying device 100. Specifically, the flap 200 has an automatic removal working state and a normally open sampling working state. In the automatic removal working state, the flap 200 actively removes the cigarette sticks 1 from the conveying device 100. In the normally open sampling working state, the flap 200 is open relative to the conveying device 100, and the cigarette sticks 1 on the conveying device 100 are removed, allowing the operator to observe manually. The normally open sampling working state will last for a first preset time, which is set to be no less than the total time that unqualified cigarette sticks 1 may have passed through the flap 200 due to machine stoppage, to ensure that unqualified cigarette sticks 1 can be completely removed at the beginning of the automatic cigarette stick removal device startup. In summary, the automatic rejection device for damaged cigarette sticks can effectively prevent unqualified cigarette sticks 1 from flowing into the next process, ensuring that all cigarette sticks 1 entering the subsequent process are qualified products, thus improving the overall product quality; the automatic rejection working state eliminates the need for frequent manual inspections, reducing time wasted due to manual operation and improving production efficiency; it also reduces the product rework rate, reduces economic losses caused by unqualified products, and lowers production costs.
[0037] The automatic rejection device for burnt cigarette sticks also includes a cigarette stick conveyor belt device 500. The downstream end of the cigarette stick conveyor belt device 500 is connected to the conveying device 100, allowing the cigarette sticks 1 produced by the cigarette stick conveyor belt device 500 to be conveyed by the conveying device 100. Optionally, the cigarette stick conveyor belt device 500 and the conveying device 100 are arranged vertically. A flap 200 is located at the connection point between the cigarette stick conveyor belt device 500 and the conveying device 100. A detection table 110 is provided on the other side of the conveying device 100 opposite to the cigarette stick conveyor belt device 500, making it easier for operators to operate. The automatic rejection device for burnt cigarette sticks is easier to install and maintain. The connection method between the components is simple and clear, facilitating quick installation and disassembly. In case of malfunction, timely repair and replacement of components are possible, ensuring long-term stable operation of the equipment.
[0038] Furthermore, the automatic rejection device for burnt cigarette sticks is equipped with a timer 310, which records the downtime of the cigarette stick conveyor belt device 500. It is worth noting that the downtime of the cigarette stick conveyor belt device 500 affects the pass rate of cigarette sticks 1 at the initial startup of the automatic rejection device. Therefore, by setting the timer 310 to record the downtime of the cigarette stick conveyor belt device 500, the flip plate 200 can be selectively placed in either the automatic rejection mode or the normally open sampling mode.
[0039] Because the longer the downtime of the cigarette pack conveyor belt device 500, the higher the defect rate of cigarette pack 1, and there is a second preset downtime, under which all cigarette pack 1 are defective products. Therefore, in this embodiment, when the downtime is less than or equal to the second preset downtime, the flip plate 200 is in the normally open sampling state, and manual observation is required to screen out defective cigarette packs 1; when the downtime is greater than the second preset downtime, all cigarette packs 1 are defective products, and the flip plate 200 is in the automatic rejection state, without the need for manual screening.
[0040] For example, if the second preset time is set to within five minutes, that is, if the downtime of the cigarette conveyor belt device 500 is greater than five minutes, then all cigarettes 1 at the beginning of the start-up need to be rejected. At this time, the rejection can be carried out by the flip plate 200 in the automatic rejection working state, which is more efficient. If the downtime is less than or equal to five minutes, then the cigarettes 1 may be unqualified. Therefore, the flip plate 200 needs to be in the normally open sampling working state, in conjunction with manual observation, so as to reject the unqualified cigarettes 1.
[0041] Specifically, the automatic rejection device for burnt cigarette sticks is equipped with a counter 320, which is located on the cigarette stick conveyor belt 500. The counter 320 is used to count the cigarette sticks 1 rejected by the flip plate 200. In particular, it counts the cigarette sticks 1 rejected by the flip plate 200 during automatic rejection operation. For example, if the downtime exceeds a second preset time, and 5 cigarette sticks 1 are determined to be defective products in the automatic rejection device for burnt cigarette sticks, the counter 320 can perform subsequent actions only after the count reaches 5. Optionally, the counter 320 can be a laser sensor.
[0042] It is understood that the automatic rejection device for burnt cigarette sticks is also equipped with a control unit. The counter 320 and timer 310 are both connected to the control unit, and the control unit stores the corresponding control program to fulfill the above functions. For example, the control unit includes a circuit board 450, which is disposed inside the housing 460.
[0043] It is worth noting that both the automatic rejection mode and the normally open sampling mode of the flip plate 200 are in the initial startup phase. After the rejection of the cigarette sticks 1 that are defective due to machine downtime is completed, the automatic rejection device for burnt cigarette sticks will enter normal operation. However, even during normal operation, there is a need for operators to manually sample the cigarette sticks 1. Therefore, in this embodiment, the flip plate 200 also has a closed mode. After the flip plate 200 has been in the normally open sampling mode for a first preset time, or after the flip plate 200 has been in the automatic rejection mode and the rejected cigarette sticks 1 meet a preset value, the flip plate 200 will be switched to the closed mode.
[0044] Specifically, when the flap 200 is in the closed state, it can open relative to the conveying device 100 upon receiving an open signal to remove the cigarette sticks 1 from the conveying device 100 for sampling by the operator. Upon receiving a close signal, it can close relative to the conveying device 100 for normal conveying of the cigarette sticks 1.
[0045] Furthermore, the automatic rejection device for burnt cigarette sticks is also equipped with a sampling start button and a sampling end button to generate open and close signals, respectively. Both the sampling start button and the sampling end button are connected to the control unit. In other embodiments, a rotary switch 440 can also be used to generate the open and close signals, resulting in a simpler structure.
[0046] To achieve the rotational movement of the flip plate 200, the automatic burnt cigarette stick removal device is also equipped with a rotary cylinder 410, and the flip plate 200 is located at the output end of the rotary cylinder 410; to achieve control of the rotary cylinder, the automatic burnt cigarette stick removal device is also equipped with a solenoid valve 420, which is connected to the rotary cylinder 410 and is also connected to the control unit, and is used to selectively place it in a certain working state according to the control program.
[0047] Specifically, when the electromagnetic coil inside the solenoid valve 420 is energized, it generates electromagnetic force, causing the valve core to move and open the air passage. Compressed air enters the rotary cylinder 410, driving the rotary cylinder 410 to rotate, which in turn causes the flap 200 to move accordingly. When the electromagnetic coil inside the solenoid valve 420 is energized, the solenoid valve 420 will switch the air passage, causing the flap 200 to close, ensuring that the tobacco stick 1 enters the next process.
[0048] Preferably, the automatic rejection device for burnt cigarette sticks is also equipped with a throttle valve, which is connected to the rotary cylinder 410 to more accurately control the gas flow and pressure entering the rotary cylinder 410, thereby enabling the rotary cylinder 410 to operate smoothly.
[0049] Furthermore, the automatic burnt cigarette stick removal device is also equipped with a flexible coupling, an air pipe 430, an air connector, and other components. The rotary cylinder 410 is connected to the flap 200 through the flexible coupling. The flexible coupling can not only ensure that the power of the rotary cylinder 410 is effectively transmitted to the flap 200, but also buffer vibration to a certain extent, ensuring that the flap 200 rotates smoothly. The rotary cylinder 410 is connected to the air source through the air pipe 430. The air pipe 430 is equipped with a throttle valve to provide power to the rotary cylinder 410 and adjust its operating speed.
[0050] For example, the automatic rejection device for burnt cigarette sticks is also equipped with an optocoupler. The optocoupler is located at the input and output ends of the control unit. The optocoupler can effectively isolate external interference signals, ensure stable and reliable signal transmission between the control circuit of the control unit and other components, and enhance the anti-interference capability of the automatic rejection device for burnt cigarette sticks.
[0051] This utility model discloses an automatic rejection device for burnt cigarette sticks, comprising a circuit board 450, a rotary cylinder 410, a flap 200, and a solenoid valve 420. When the packaging equipment is in continuous production, the flap 200 is closed, ensuring that the produced cigarette sticks can smoothly enter the overhead conveyor channel. When the packaging equipment stops production due to malfunction or other reasons, the timer 310 in the circuit board 450 starts counting. After the timer 310 reaches the set time, the circuit board 450 sends a signal to the solenoid valve 420 to switch the air path, the rotary cylinder 410 actuates, and the flap 200 opens. When the packaging equipment resumes production, the burnt cigarette sticks can be rejected along the flap 200. The number of rejected cigarette sticks is counted by the counter 320 at the cigarette stick outlet. After reaching the set number, the circuit board 450 re-controls the flap 200 to close. This utility model's automatic rejection device for burnt cigarette sticks can effectively reject unqualified cigarette sticks, which is of great significance for improving the product quality of automatic rejection devices for burnt cigarette sticks.
[0052] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
