[0059] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be construed as a limitation to the present invention.

[0060] The present invention provides an embodiment of a method and system for automatically classifying and collecting unqualified cigarette packs. Specifically, as Figure 1 shown, which includes:

[0061] In this embodiment, the unqualified cigarette pack automatic classification and collection system is provided with a rejection mechanism 4 at the end of the outlet of the packaging main machine 1. The rejection mechanism 4 is a bypass on the main production line and is used to identify and reject the cigarette packs that do not meet the production requirements. The rejected cigarette packs then turn to the bypass and do not affect the normal operation of the main production line.

[0062] A visual detection device is provided on the rejection mechanism 4, which can be an AI camera. By taking images of unqualified cigarette packs and cooperating with the controller to identify the defect degree of the cigarette packs, and classifying the defect degree according to preset levels, such as first-level defects, second-level defects, third-level defects, fourth-level defects, etc.;

[0063] A rotating device is provided below the rejection mechanism 4. A plurality of collection bins 3 are arranged at the circumferential position of the rotating device. The collection bins 3 are marked in advance according to the unqualified levels, such as a first-level collection bin, a second-level collection bin, a third-level collection bin, a fourth-level collection bin, etc. The rotating device can rotate above the collection bins 3 to convey the unqualified cigarette packs into the collection bins 3.

[0064] The rotating device includes:

[0065] A motor 21, and the motor 21 is fixed at the outlet position of the packaging main machine 1;

[0066] A base 22 fixedly connected to the motor 21, a rejection guide plate 23 fixedly connected to the base 22. The rejection guide plate 23 is inclined. The motor 21 and the rejection guide plate 23 are respectively installed at opposite ends of the base 22, and the rejection guide plate 23 can rotate with the motor 2I. The rejection guide plate 23 includes: a connecting plate 231 fixedly connected to the base 22, and a guide channel 232 fixedly connected to the connecting plate 231. A first detector is provided at the outlet end of the guide channel 232 to detect whether the unqualified cigarette pack at the outlet end of the guide channel 232 at the current moment has slipped out of the guide channel 232. If the cigarette pack has slipped, a third signal is output.

[0067] A deceleration mechanism is provided on the front side of the rejection guide plate 23, and an acceleration mechanism is provided on the rear side of the rejection guide plate 23. The moving speed of the cigarette packets on the rejection guide plate 23 is controlled by the deceleration mechanism and the acceleration mechanism. Since the rejection guide plate 23 is inclined, the cigarette packets will freely slide along the rejection guide plate 23 due to gravity and fall into the collection box 3. At this time, by setting the deceleration mechanism and the acceleration mechanism, the moving speed of the cigarette packets can be controlled.

[0068] Both the deceleration mechanism and the acceleration mechanism here adopt blowing devices, and the blowing devices are also controlled by the controller, and the blowing pressure of the blowing devices is collected in real time. According to the magnitude of the required blowing pressure, the amount of compressed air of the blowing devices is adjusted.

[0069] In another implementation, a pitching motor is provided at the connection between the rejection guide plate 23 and the base 22. The pitching angle of the rejection guide plate 23 is adjusted by the pitching motor, the inclination of the rejection guide plate 23 is adjusted, and thus the moving speed of the cigarette packets is adjusted.

[0070] Second detectors are provided at both ends of the collection box 3, and the second detectors are electrically connected to the controller; when the collection box 3 is full, the second detector outputs a fourth signal to remind the staff to replace the box as soon as possible. In this embodiment, the above-mentioned electrical components are all connected to the controller, and the collected information is transmitted to the controller, and the controller controls the cooperation of each structure. Optionally, the controller can adopt a PLC.

[0071] In this embodiment, when automatically classifying and collecting unqualified cigarette packets:

[0072] Step 11, obtain the first signal of the vision detection device, and the first signal includes the defect image of the unqualified cigarette packet;

[0073] Step 12, determine the unqualified level of the unqualified cigarette packet according to the first signal;

[0074] Step 13, according to the unqualified level, control the rotating device to rotate to the collection box 3 at the preset position.

[0075] Specifically, when the rejection mechanism 4 rejects an unqualified cigarette packet, the vision detection device takes a picture of the cigarette packet at the same time and transmits the picture to the controller. The controller obtains the unqualified level of the cigarette packet according to the degree of defect, and classifies the unqualified level according to the preset level, such as first-level defect, second-level defect, third-level defect, fourth-level defect, etc. The cigarette packet falls on the rejection guide plate 23, and the rejection guide plate 23 turns to the upper part of the collection box 3 matching the unqualified level.

[0076] If the unqualified cigarette pack at this time is a first-level defect, the controller controls the motor 21 to drive the rejection guide plate 23 to turn towards the first collection box, and sends the cigarette pack into the collection box. At this time, the first detector sends a signal to determine that the cigarette pack has fallen from the rejection guide plate 23.

[0077] When there are two or more cigarette packs on the rejection guide plate 23 at the same time, since the unqualified levels of the cigarette packs may be different, they need to be placed in different collection boxes 3. At this time, the visual detection device sends a second signal, and the controller activates the deceleration mechanism to slow down the sliding speed of the cigarette packs, providing sufficient time for the rejection guide plate 23 to rotate to the preset position.

[0078] When the sliding of the cigarette pack is blocked, such as when there are foreign objects on the surface of the rejection guide plate 23, the controller activates the acceleration mechanism to provide auxiliary external force for the smooth sliding of the cigarette pack.

[0079] The above embodiments of the present invention solve the problems that the existing cigarette packs accumulate at the rejection outlet, cannot be quickly classified, resulting in the concentrated stacking of unqualified cigarette packs, affecting the cleanliness of the production site, and the excessive accumulation of defective cigarette packs also affects the normal operation of the equipment and the normal work of the operation and maintenance personnel. It improves the production efficiency, saves energy consumption, and meets the requirements of the production task.
