Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0016] like Figures 1-3 As shown, this embodiment provides a small box rejection and separation device for a cigarette packaging machine, including a mounting base plate 1. A protective shell plate 2 is provided at the top of the mounting base plate 1. A flip-plate separation assembly 3 is provided on the upper part of the protective shell plate 2. An electrical control box 4 and two rejection bins 5 are provided at the lower part of the protective shell plate 2, mounted on the mounting base plate 1. The flip-plate separation assembly 3 includes a separation guide box 301 located at the top of the protective shell plate 2. A box discharge port 302 is provided at the connection between the separation guide box 301 and the protective shell plate 2. A box filling port 303 is provided at the top of the separation guide box 301. A first partition plate 304 is provided inside the separation guide box 301 and connected to the same side as the box discharge port 302 and the box filling port 303. A separation flip plate 305 is connected to the cavity formed by the first partition plate 304 and the separation guide box 301 via a bearing. The material of the separation flip plate 305 is... Made of POM plastic, the first partition plate 304 is equipped with a rotary cylinder 306 that drives the separation flap 305 to rotate via bearings. The solenoid valve 9 changes the airflow direction and controls the rotary cylinder 306 to operate. The rotary cylinder 306 rotates the separation flap 305 to a set angle, guiding the rejected small boxes to fall into the corresponding rejection bin 5. After the small boxes have completely fallen, the separation flap 305 resets, completing the small box separation action. Using the rotary cylinder 306 to control the action of the separation flap 305 is more efficient than using a regular straight rod cylinder, and the rotation angle is easier to adjust. The separation flap 305 is made of POM plastic, which makes the surface of the separation flap 305 smooth, facilitating the sliding of the small boxes. The rotation angle range of the separation flap 305 is 90°-150°, controlled by the solenoid valve 9.

[0017] The top of the separating guide box 301 is provided with a rejection feed cover 307 covering the box filling opening 303. The rejection feed cover 307 is L-shaped and has an opening at the top. The rejected small boxes enter the rejection feed cover 307 and are then separated.

[0018] The mounting base plate 1 has a vertically upward second partition plate 6 in the middle, and two rejection bins 5 are respectively located on both sides of the second partition plate 6; the top of the second partition plate 6 has an extension connecting plate 7 that extends upward and into the box discharge port 302. The setting of the second partition plate 6 and the extension connecting plate 7 can ensure that the small box falls accurately into the corresponding rejection bin 5.

[0019] The electrical control box 4 is equipped with an air supply line 8 that supplies air to the rotary cylinder 306. A solenoid valve 9 is installed on the air supply line 8. The solenoid valve 9 is used to change the airflow direction and control the rotary cylinder 306 to move.

[0020] The air supply pipeline 8 is equipped with an air source oil-water filter 10. The rejection action is achieved by the rotary cylinder 306. The air supply pipeline 8 is connected to the air source filter 10 for filtration before supplying air to the rotary cylinder 306.

[0021] The electrical control box 4 is equipped with a photoelectric sensor 11. The photoelectric sensor 11 is used to detect the action and improve the sorting accuracy. The photoelectric sensor 11 can detect the position of the separation flip plate 305 or the state of the small box falling.

[0022] During operation, this equipment operates in two modes: intermittent rejection and continuous rejection. In the intermittent rejection mode, the rejection signal is frequently issued. The solenoid valve of this device redirects the airflow according to the rejection signal, controlling the rotary cylinder to repeatedly flip and reset. The time interval between these actions is determined by the rejection interval of the original machine. In the continuous rejection mode, this device operates only once. After the continuous rejection is completed, the device's flip plate resets.

[0023] The structure and principle of this rejection and separation device can be applied to the rejection and separation of small cigarette packs, including standard cigarettes, medium cigarettes, slim cigarettes, hard-pack cigarettes, and soft-pack cigarettes.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] During operation: After the original machine's PLC controller receives the NG signal from the code reader, the original machine rejects the NG box (this is prior art, known to those skilled in the art). Upon receiving the rejection signal, the rejection separation device activates the solenoid valve 9 to change the airflow direction, controlling the rotary cylinder 306 to operate. The rotary cylinder 306 rotates the separation flip 305 to a pre-set angle, guiding the rejected box to fall into the corresponding rejection bin 5. After the box has completely fallen, the separation flip 305 resets, completing the box separation action. The rotary cylinder then... The cylinder 306 controls the movement of the separating flap 305, which is more efficient than using a conventional straight-rod cylinder. The rotation angle is also easier to adjust. The separating flap 305 is made of POM plastic, making its surface smooth and facilitating the sliding of small boxes. The rotating cylinder 306 is controlled by a solenoid valve 9, and a photoelectric sensor 11 detects the movement. This rejection and separation device uses compressed gas as a power source, ensuring safety and efficiency. It is also highly versatile, suitable for rejecting and separating small boxes with QR codes on ZB45 / 25, GDX1 / X2, and ZB47 models. Rejection of small boxes mainly includes rejection due to appearance issues and rejection due to QR code problems. This device can accurately and quickly distinguish the specific reason for rejection, facilitating subsequent classification and processing. The control principle is simple, the structure operates smoothly, and it will not damage the rejected cigarette boxes. The overall size of this rejection and separation device is small, occupying little space in the original machine, and its external installation is simple and has no impact on the original machine's condition.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
