[0053] like Figure 1 As shown, this application provides a cigarette stick rotation and pushing device, including: a cigarette stick longitudinal conveying module 1, a cigarette stick transverse conveying module 2, a servo motor driven rotation mechanism 3, a human-machine interface 4, and an electrical control cabinet 5.

[0054] The longitudinal conveying module 1 for cigarette sticks includes: a first frame, a first conveyor belt, a first front conveyor roller, a first rear conveyor roller, sensor I, sensor II, and motor I.

[0055] A connecting plate is provided between the longitudinal conveying module 1 and the transverse conveying module 2 of the cigarette sticks to allow the cigarette sticks to pass through.

[0056] Sensor I is installed at the inlet of the longitudinal conveying module 1 to detect the presence of cigarette sticks and whether there is any blockage at the inlet. Elliptical holes are provided on both sides of the inlet of the first frame. The first front conveying roller is mounted on a shaft that passes through the elliptical holes, allowing it to be mounted on the frame. The first front conveying roller rolls on the shaft. Both ends of the shaft are elliptical and have threaded holes. One end of a lead screw passes through the threaded hole on the shaft, and the other end is connected to a fixed seat on the frame. Adjusting the position of the lead screw changes the forward and backward position of the first front conveying roller, thereby adjusting its tension and correcting the position of the first conveyor belt to prevent skewing. Sensor II is installed at the end of the longitudinal conveying module 1 to detect whether the cigarette sticks are in place and whether there is any blockage at that station. A rectangular baffle is provided at the sensor II station to block the cigarette sticks. Figure 3 This is a diagram showing the state of the cigarette pack after it has been placed in place according to this application.

[0057] The first frame has round holes on both sides at its end. The first rear conveyor roller passes through the round holes, with one end connected to motor I1 and fixed to the first frame, and the other end connected to a bearing seat and fixed to the first frame. Motor I drives the first rear conveyor roller, thereby driving the first conveyor belt.

[0058] The transverse cigarette conveying module 2 consists of a second frame, a second left conveyor belt, a second right conveyor belt, a second front left conveyor roller, a second rear left conveyor roller, a second front right conveyor roller, a second rear right conveyor roller, and a motor II. The transverse cigarette conveying module 2 is similar to the longitudinal cigarette conveying module 1, except that it has two conveyor belts. The second left conveyor belt is mounted on the second front left conveyor roller and the second rear left conveyor roller. The second right conveyor belt is mounted on the second front right conveyor roller and the second rear right conveyor roller.

[0059] like Figure 2As shown, the servo motor-driven rotating mechanism 3 includes: a servo motor 31, sensor III 321, sensor IV 322, a protective cover 33, a rotating push plate 34, and a clutch 35. The protective cover 33 is a hollow cylinder with an opening at the bottom to provide space for the cigarette bar to move. The protective cover 33 is fixed to the end of the first frame via a connecting block. A circular hole 331 is located at the center of one side of the protective cover 33, and an arc-shaped hole 332 is located above the circular hole 331. The servo motor 31 passes through the circular hole 331 and is mounted on the protective cover. The first sensor 321 passes through the arc-shaped hole 332 and is mounted on the protective cover 33. Sensor III 321 detects the position of the rotating push plate 34. One end of the clutch 35 is connected to the motor 31, and the other end is connected to the rotating push plate 34. Sensor IV 322 is located on the clutch 35 to detect the disengagement and engagement states of the clutch 35. The rotating push plate 34 consists of a rod-shaped handle 341 and a cylindrical push plate 342. There are two cylindrical push plates 342, symmetrically arranged at both ends of the rod-shaped handle 341. The surface of the push plates 342 is provided with a cushioning material. The cushioning material can be an impact-resistant layer made of a soft material applied to the surface of the push plates 342.

[0060] A human-machine interface 4 is located in the middle and rear section of the transverse conveyor module 2. The human-machine interface 4 is fixed to the frame of the transverse conveyor 2 via a bracket. The operating status of the equipment can be viewed through the human-machine interface 4. The human-machine interface 4 can rotate clockwise or counterclockwise by a maximum of 160°, and the bracket of the human-machine interface 4 can rotate clockwise or counterclockwise by a maximum of 90°. The housing of the human-machine interface 4 is equipped with reset, stop, start, and emergency stop switches for controlling the cigarette bar rotation and pushing device. An electrical control cabinet 5 is located below the second frame of the transverse conveyor module 2. The electrical control cabinet 5 has a main power switch on the outside. The electrical control cabinet 5 contains electrical components such as a PLC, frequency converter, servo controller, air switch, and relays.

[0061] like Figure 3 As shown, the electrical control system of the servo motor driven rotary mechanism is based on a PLC. The servo controller, frequency converter, and sensors work together to complete the electrical control of the equipment. The PLC receives signals from the sensors, frequency converter, servo controller, etc., processes them, and then outputs signals to the actuators.

[0062] The process flow of this application is as follows: Figure 4 As shown, the specific steps are as follows:

[0063] 1) Connect the power supply to the equipment and press the reset switch. The equipment will perform a self-check of its own status. If there is a fault, it will alarm. If there is no fault, it will enter the preparation state and wait to start.

[0064] 2) Press the start switch to start the equipment and perform initialization work. The longitudinal conveying starts. After a set time T1, the rotating push plate 34 rotates. The sensor III321 detects the rotating push plate 34, and the rotating push plate 34 stops moving. Then the transverse conveying starts.

[0065] 3) If sensor I does not detect the presence of the cigarette bar after a set time T2, the equipment enters a waiting state and stops running all conveyor belts until sensor I detects the cigarette bar, at which point the equipment enters the running state.

[0066] 4) When sensor II detects the presence of the cigarette bar, the rotating pusher plate starts to move, and stops moving after rotating to the set angle;

[0067] 5) If sensor I or sensor II detects a cigarette bar and the sensor signal does not change after a set time T3, then a cigarette bar blockage occurs at the corresponding sensor position, the equipment stops and alarms, and sends an equipment fault signal to the upstream machine.

[0068] 6) The rotating push plate starts to move. The servo controller monitors the position of the rotating push plate 34. If the rotating push plate 34 does not reach the set position within the set time T4, it is determined that the rotating push plate 34 has malfunctioned. The equipment stops and alarms, and sends an equipment fault signal to the upstream machine.

[0069] If the rotating push plate 34 reaches the set position at the set time T4, the rotating push plate 34 will stop moving.

[0070] 7) Sensor IV322 monitors the clutch disengagement and engagement status. During normal operation, the clutch is engaged and sensor IV322 detects the clutch.

[0071] When the clutch disengages, sensor IV322 cannot detect the clutch, determines that the clutch has malfunctioned, the equipment stops and alarms, and sends an equipment fault signal to the upstream machine.

[0072] Motors I and II are geared motors, controlled by a frequency converter installed in the electrical control cabinet 5. The frequency converter allows setting parameters such as the rotation frequency and acceleration / deceleration of motors I and II, while also monitoring their current and torque. Servo motor 31 is driven by a servo controller. The servo controller allows setting parameters such as the frequency, initial position, and stop position of servo motor 31, while also monitoring its current and movement position. When motors I, II, or servo motor 31 malfunction, the frequency converter and servo controller stop operating and send a fault signal to the PLC, halting the equipment's operation and simultaneously sending a fault signal to the upstream machine.

[0073] The speeds of the longitudinal conveying module 1 and the transverse conveying module 2 can be adjusted in two ways:

[0074] 1) The speed of the motor can be adjusted by adjusting the output frequency of the corresponding frequency converter that controls the motor;

[0075] 2) Change the diameter of the conveyor roller. The larger the diameter of the conveyor roller, the greater the movement speed of the conveyor module.

[0076] In addition, the speed of the servo motor 31 can be adjusted by modifying the parameters of the servo controller.
