Description

Technical Field

[0001] The present application relates to the technical field of tobacco manufacturing, and more specifically, to a tobacco rod defect detection device and method for a packaging machine. Background Art

[0002] During the production and operation of the auxiliary equipment of the GDX packaging machine, the cigarette strips after folding the box are put through the transparent paper wrapping forming and heat sealing system, and then pushed into the beauty section by the cigarette strip output push rod. After the cigarette strips are beautified with transparent paper in the first and second beautifiers, they pass through the conveying channel to the input end of the cigarette strip elevator, and after being vertically lifted by the cigarette strip elevator, they are weighed by the weighing device on the horizontal conveyor belt and conveyed to the carton sealing machine.

[0003] However, due to various reasons, such as poor folding and pasting of the strip box, or poor folding and heat sealing of the transparent paper of the strip box, the cigarette rods output from the wrapping, forming and heat sealing system have quality defects, such as uneven strip box, loose transparent paper, loose strips, etc. Such quality defects may cause the cigarette rods to be blocked in front of the first beautifier. If the unqualified cigarette rods successfully pass through the first beautifier and the second beautifier and are vertically lifted by the cigarette rod lifter, the cigarette rods will be blocked in front of the weighing device on the horizontal conveyor belt or in front of the main drive motor of the conveyor belt during the horizontal conveying process, causing the cigarette rod lifter to stop. At this time, the unqualified cigarette rods need to be removed before the cigarette rod lifter can be restarted, which is time-consuming and labor-intensive. If the cigarette rods are blocked in front of the drive motor, it may also cause the cigarette rods to be blocked one by one, resulting in more quality-defective cigarette rods.

[0041] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0042] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0043] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0044] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0045] The present application provides a device and method for detecting tobacco rod defects of a packaging machine, which detects defective tobacco rods in time and issues an alarm through a photoelectric sensor installed at the output end of a transparent paper wrapping, forming and heat-sealing system or the input end of a beauty section, thereby avoiding blocking subsequent tobacco rod conveying channels.

[0046] like Figure 1 As shown, the packaging machine includes a transparent paper wrapping forming and heat sealing system (not shown in the figure, located on the left side of the first beauty device), a first beauty device 3, a second beauty device 4, a first horizontal conveyor belt 5, a second horizontal conveyor belt 9 and a cigarette rod lifter 10. The cigarette rod lifter 10 is controlled by a lifter controller 12.

[0047] The tobacco strip 20 formed after the transparent paper wrapping, forming and heat-sealing system is pushed into the beauty section by the push rod 19 at the output end of the transparent paper wrapping, forming and heat-sealing system. The beauty section includes a first beauty container 3 and a second beauty container 4. The tobacco strip is pushed into the first beauty container 3 and the second beauty container 4 in sequence for transparent paper beauty treatment, and then from the output end of the second beauty container 4 through the first horizontal conveyor belt 5, the transition conveyor plate, and the second horizontal conveyor belt 9 conveying channel to the input end of the tobacco strip lifter 10. After being vertically lifted by the tobacco strip lifter 10, it is conveyed to the carton sealing machine via the third horizontal conveyor belt.

[0048] As an embodiment, the tobacco rod defect detection device of the packaging machine provided in the present application includes a first photoelectric sensor, a controller and a first alarm.

[0049] The first photoelectric sensor is installed on the side wall of the output end of the transparent paper wrapping forming and heat sealing system or the input end of the beauty section of the packaging machine, and the distance between the first photoelectric sensor and the bottom surface of the output end of the transparent paper wrapping forming and heat sealing system or the bottom surface of the input end of the beauty section is greater than the thickness of the tobacco rod. Figure 1 and 2 As shown, as an embodiment, the first photoelectric sensor 21 is installed on the inner wall of the front side plate 18 of the input end 1 of the first beauty device 3, and the installation position of the first photoelectric sensor 21 is higher than the top of the tobacco rod.

[0050] As an embodiment, the controller is a PLC controller of a packaging machine. It can be understood that the controller can also be a newly added local controller.

[0051] As an example, Figure 1 As shown, the first alarm is a light alarm 7 , which is installed on the outer side of the side wall of the first horizontal conveyor belt 5 .

[0052] The controller is signal-connected to the first photoelectric sensor 21 and the first alarm respectively.

[0053] If the cigarette box is uneven, the transparent paper is loose or scattered, and the top surface of the cigarette rod is higher than the height of the first photoelectric sensor 21, the first photoelectric sensor 21 is triggered, and the first photoelectric sensor 21 sends a first cigarette rod defect signal to the controller. After receiving the first cigarette rod defect signal, the controller sends an alarm signal to the first alarm, and the alarm sounds to remind the operator to deal with it in time to prevent unqualified cigarette rods from entering the cigarette rod elevator.

[0054] Preferably, if Figure 2 As shown, the tobacco rod defect detection device further includes a second photoelectric sensor 22, which is mounted on the inner side wall of the front side plate 18 of the output end of the transparent paper wrapping forming and heat sealing system or the input end of the beauty section of the packaging machine. The second photoelectric sensor 22 is higher than the first photoelectric sensor 21 relative to the bottom surface of the output end of the transparent paper wrapping forming and heat sealing system or the bottom surface of the input end of the beauty section. As an embodiment, Figure 2 As shown, the second photoelectric sensor 22 is directly above the first photoelectric sensor 21. The second photoelectric sensor 22 is connected to the controller signal.

[0055] When the top surface of the cigarette rod is higher than the height of the second photoelectric sensor 22, the second photoelectric sensor 22 is triggered, and the second photoelectric sensor 22 sends a second cigarette rod defect signal to the controller. After receiving the second cigarette rod defect signal, the controller sends a stop command to the auxiliary start and stop switch of the packaging machine, forcing the operator to handle it, so as to avoid unqualified cigarette rods being blocked in the first beauty device or the second beauty device, causing cigarette rods to stack.

[0056] Preferably, the tobacco rod defect detection device further comprises a third photoelectric sensor, which is installed at the output end of the beauty section, the input end of the tobacco rod lifter of the packaging machine, or between the output end of the beauty section and the input end of the tobacco rod lifter. Figure 1 As shown, as an embodiment, the third photoelectric sensor 15 is installed on the fixed conveying channel 8 between the output end of the beauty section and the input end of the tobacco rod lifter 10. The third photoelectric sensor 15 is connected to the controller signal.

[0057] In the preferred embodiment, the controller includes a counter.

[0058] The counter starts after the controller receives the first cigarette rod defect signal from the first photoelectric sensor 21. After the cigarette rod passes through the third photoelectric sensor 15, the third photoelectric sensor 15 generates a cigarette rod signal and sends it to the controller. Every time the controller receives a cigarette rod signal from the third photoelectric sensor, the counter increases by one.

[0059] Preferably, if Figure 2 As shown, a fixed conveying channel 8 and a state switching channel 6 are included between the output end of the beauty section and the input end of the cigarette rod lifter. The first end of the fixed conveying channel 8 is fixedly connected to the output end of the beauty section, and the second end of the fixed conveying channel 8 is rotatably connected to the first end of the state switching channel 6. Under normal working conditions, the second end of the state switching channel 6 abuts against the second horizontal conveyor belt 9; under abnormal processing conditions, the second end of the state switching channel 6 is separated from the second horizontal conveyor belt 9. A manual packing platform 17 is provided below the state switching channel 6. It can be understood that in some embodiments, the second horizontal conveyor belt 9 can be cancelled. Under normal working conditions, the second end of the state switching channel 6 directly abuts against the input end of the cigarette rod lifter 10, and the cigarette rods directly enter the input end of the cigarette rod lifter 10 from the state switching channel 6.

[0060] As an embodiment, the driving component of the state switching channel 6 includes a solenoid valve and a cylinder 14. The solenoid valve is connected to the controller signal; the cylinder 14 is connected to the solenoid valve, the end of the piston rod of the cylinder 14 is fixedly connected to the second end of the state switching channel 6, and the base of the cylinder is fixedly connected to the support 2 of the fixed delivery channel 8.

[0061] Preferably, the tobacco rod defect detection device further comprises a second alarm, and the second alarm is connected to the controller signal. Figure 1 As shown, the second alarm is a buzzer 11 , and the buzzer 11 is installed on the lift controller 12 .

[0062] When the number of cigarette rods counted by the counter is greater than the predetermined number, the controller sends a switching command to the solenoid valve, which controls the piston rod of the cylinder 14 to retract, and the state switching channel 6 rotates downward relative to the fixed conveying channel 8. After the cigarette rods move to the lower end of the fixed conveying channel 8, they freely fall to the manual packing platform 17, and the cigarette rods are manually packed to prevent unqualified cigarette rods from entering the cigarette rod lifter 10. At the same time, the controller controls the buzzer 11 to sound and the light alarm to flash, reminding the operator to handle and avoid clogging of the cigarette rod conveyor belt.

[0063] Preferably, a first reset switch 16 is provided on the light alarm 7. The first reset switch is connected to the controller signal. After pressing the first reset switch 16, the light alarm stops flashing, the alarm stops, and the counter in the controller stops counting.

[0064] Preferably, the lift controller 12 further includes a second reset switch 13, which is respectively connected to the electromagnetic valve and the buzzer 11. After pressing the second reset switch 13, the electromagnetic valve is reset, the piston rod of the cylinder 14 extends, the second end of the state switching channel 6 abuts against the second horizontal conveyor belt 9 or the input end of the cigarette rod lifter 10, and the cigarette rod conveying enters a normal working state; at the same time, the buzzer stops beeping.

[0065] The present application also provides a method for detecting tobacco rod defects of a packaging machine that matches the above-mentioned tobacco rod detection device, and the method is suitable for a controller. Figure 3 As shown, the cigarette rod defect detection method includes:

[0066] S310: Receive a first cigarette rod defect signal from a first photoelectric sensor.

[0067] S320: In response to receiving the first cigarette rod defect signal, an alarm signal is sent to the first alarm device, so that the operator can handle the fault in time.

[0068] Preferably, the cigarette rod defect detection method further comprises:

[0069] S330: starting a counter in response to receiving the first tobacco rod defect signal.

[0070] S340: In response to receiving the tobacco rod signal from the third photoelectric sensor, the counter is incremented by one.

[0071] S350: If the count value of the counter is greater than the predetermined number, that is, the number of cigarette rods exceeds the predetermined number, a control signal is sent to the solenoid valve and the second alarm. The solenoid valve switches the channel through the cylinder control state, so that the cigarette rods fall into the manual packing table 17 to avoid the blockage of the conveyor belt, and the second alarm reminds the operator to handle the fault.

[0072] In this preferred embodiment, if the operator fails to handle the problem in time after the first alarm sounds, it is likely to cause the conveyor belt to be blocked and spread to the tobacco rod lifter. Therefore, if the number of tobacco rods passing through the third photoelectric sensor exceeds a predetermined number, the blockage is relieved through the channel between the terminal state switching channel and the third horizontal conveyor belt 9 or the tobacco rod lifter 10.

[0073] Preferably, the cigarette rod defect detection method further comprises sending a stop command to the auxiliary machine start-stop switch in response to receiving a second cigarette rod defect signal from the second photoelectric sensor.

[0074] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
