Description

Technical Field

[0001] The invention relates to the technical field of cigarette rejection control, and in particular to a control system for a reject baffle of a cigarette making machine. Background Art

[0002] During the operation of ordinary equipment for transporting cigarettes, the rejection roller rolls clockwise to transfer qualified cigarettes to the last transfer roller that rolls counterclockwise. There is a high-speed rejection solenoid valve for waste cigarettes on the ordinary rejection wheel. The rejection position of waste cigarettes is at the end of the clockwise rotation of the rejection roller. When unqualified cigarettes are detected, the high-speed rejection solenoid valve for waste cigarettes will be activated to reject them. However, when the solenoid valve is not sensitive or the rejection air pressure is low, the rejection will be delayed, and the rejected cigarettes will be kicked to the last transfer roller, so that the waste cigarettes are sandwiched between the rejection roller and the last transfer roller, which will cause messy and rotten cigarettes to the normally transmitted cigarettes. A high-speed rejection valve costs about 6,000 to 7,000 yuan. If the high-speed rejection valve is replaced or repaired when it is not sensitive, the maintenance cost will increase, which will increase the production cost of cigarettes. Therefore, it is of great significance to prevent the rejected cigarettes from falling on the transfer roller when the rejection valve is not sensitive. Summary of the invention

[0027] In order to more clearly illustrate the specific embodiments of the present invention, the drawings required for use in the embodiments will be briefly introduced below.

[0030] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and the embodiments.

[0031] Aiming at the problem that the normal cigarettes on the transfer roller are likely to be disrupted or collided during the rejection of waste cigarettes, the present invention provides a control system for the rejection baffle of waste cigarettes in a cigarette making machine, which solves the problem that waste cigarettes are likely to fall onto the last transfer roller during rejection in the existing cigarette making machine, and can avoid the normal cigarettes on the transfer roller from being disrupted or collided, improving the product quality of cigarette production.

[0032] As Figure 1 and Figure 2 shown, a control system for the rejection baffle of waste cigarettes in a cigarette making machine includes: a controller, a rejection baffle 1, a stepping motor driver, and a stepping motor. The rejection baffle 1 is arranged at the waste cigarette rejection position between the rejection roller and the last transfer roller to form a separation between the rejected waste cigarettes 2 and the last transfer roller. The stepping motor is arranged on the MAX wallboard around the rejection roller, the rotating shaft of the stepping motor is connected with a mounting bracket, and the rejection baffle is arranged on the mounting bracket. When the stepping motor rotates, it drives the rejection baffle to adjust the tilt angle to adapt to the rejection trajectory of the waste cigarettes. The controller is signal-connected to the stepping motor driver and controls the operation of the stepping motor through the stepping motor driver.

[0033] Specifically, an ejection baffle is installed at the ejection position of the rejected cigarettes on the rejection wheel to isolate the rejected cigarettes from the last transfer roller. A bracket is installed at the ejection baffle, and the other end of the bracket is installed at the rotating position of the stepping motor, and the stepping motor is fixed on the MAX wallboard near the rejection roller. A baffle connecting rod can be connected to the rotating shaft of the stepping motor, and the other end of the baffle connecting rod is connected to the ejection baffle, enabling the ejection baffle to rotate with the rotation of the stepping motor. The controller controls the rotation of the stepping motor to drive the ejection baffle to tilt upward or downward by a corresponding angle, thereby blocking the rejected cigarettes and preventing them from being clamped between the rejection wheel and the last transfer wheel. This can avoid the normal cigarettes on the transfer roller from being disrupted or collided, improving the product quality of cigarette production.

[0034] The system further includes: a pressure sensor P; the pressure sensor P is arranged at the air outlet of the ejection valve and is signal-connected to the controller to detect the pressure at the air outlet of the ejection valve. When the pressure at the air outlet of the ejection valve is not within the set range, the controller controls the stepping motor to rotate to adjust the tilt angle of the ejection baffle according to the pressure at the air outlet of the ejection valve, and reports an alarm for abnormal air outlet pressure.

[0035] In practical applications, a pressure sensor is installed at the air outlet of the ejection valve, which can generate different voltage signals according to different air pressures. The air pressure analog signal is transmitted to the stepping motor controller to control the stepping motor to rotate at different angles according to different air pressures, thereby controlling the rotation of the stepping motor to drive the baffle to tilt upward or downward by a corresponding angle to block the rejected cigarettes and prevent them from being clamped between the rejection wheel and the last transfer wheel.

[0036] The system further includes: an alarm device; the alarm device is signal-connected to the controller, and when the pressure at the air outlet of the ejection valve is less than the set threshold, the controller controls the alarm device to give an alarm.

[0037] Furthermore, the alarm device at least includes any one of the following: an indicator light, a buzzer, and an audible and visual alarm.

[0038] The system further includes: a reset switch k1; the reset switch k1 is signal-connected to the controller, and when the reset switch k1 is closed, the controller controls the stepping motor to rotate to make the ejection baffle in the initial position.

[0039] The system further includes: a position sensor k3; the position sensor k3 is signal-connected to the controller and is used to detect whether the rotation angle of the ejection baffle exceeds 3°; when the rotation angle of the ejection baffle exceeds 3°, the controller controls the alarm device to give an alarm and prompts to replace the ejection valve.

[0040] The system further includes: a manual jog switch k2; the manual jog switch k2 is signal-connected to the controller, and the controller controls the stepper motor to be in jog control when the manual jog switch k2 is closed, so as to manually adjust the tilt angle of the rejection baffle.

[0041] In practical applications, the reset switch and the manual jog switch can adopt push-button switches, and the in-place sensor adopts a limit switch. When the air outlet pressure of the rejection valve is not at the normal pressure value, the stepper motor rotates forward and backward accordingly. When the stepper motor rotates to 3 degrees of the initial phase, at this time the in-place sensor acts, indicating that the air guiding of the rejection valve is seriously blocked, the replacement rejection valve alarm light is on. After pressing the reset button for the replacement rejection valve, the baffle returns to the initial position again. Pressing the manual jog button of this device can perform the manual operation of the stepper motor, so as to achieve a better rejection and shielding angle for waste cigarettes. When the manually operated baffle reaches the 3-degree position of the initial phase and triggers the in-place sensor, the stepper motor rotates in the reverse direction until it reaches the initial position, and then the stepper motor rotates in the forward direction (the direction in which the baffle rotates upward) until the stepper motor stops after stopping pressing the jog button.

[0042] The system further includes: a touch screen; the touch screen is signal-connected to the controller, and a human-machine interaction operation interface is provided on the touch screen, and the operator can remotely switch the manual jog switch and / or the reset switch through the touch screen.

[0043] Further, the rejection baffle is a quarter-arc structure with a radius of 15 cm, and the arc length is less than 4 cm.

[0044] Further, the controller is a PLC controller.

[0045] It can be seen that the present invention provides a rejection baffle control system for waste cigarettes of a cigarette machine. A rejection baffle is arranged between the rejection roller and the last transfer roller, and the controller controls the rotation of the stepper motor to drive the rejection baffle to adjust the tilt angle. It solves the problem that waste cigarettes are easily dropped onto the last transfer roller during rejection of the existing cigarette machine, and can avoid the normal transferred cigarette sticks on the transfer roller from being disrupted or collided, and improves the product quality of cigarette stick production.
