[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] Example 1:

[0035] like Figure 1 As shown, this embodiment provides an automatic cigarette sorting device, including: a centrifugal turntable 100, a feeding hopper 200, and a cigarette sorting mechanism 300; the bottom of the feeding hopper 200 is fixed to the centrifugal turntable 100 and arranged coaxially; the centrifugal turntable 100 is provided with a rotation drive device 110 for driving the centrifugal turntable 100 to rotate; the inner wall of the feeding hopper 200 is provided with a spiral lifting track 210; the discharge port at the upper end of the feeding hopper 200 is higher than the rest of the upper end surface of the feeding hopper; the width of the lifting track 210 at the outlet is adapted to the diameter of a single cigarette; the cigarette sorting mechanism 300 is used to sort and collect the incoming cigarettes according to defective cigarettes and the orientation of the filter tip relative to the cigarette output direction.

[0036] This embodiment addresses the issue of currently recycled cigarettes being in a disordered state by designing a centrifugal turntable. The disordered cigarettes are guided into the turntable, where centrifugal force and the inner wall track of the hopper separate them into individual cigarettes, which are then conveyed upwards along the track. These upward-conveyed cigarettes are transported through a cigarette conveying channel to a cigarette sorting mechanism, where they are sorted and collected using visual recognition technology. During operation, waste cigarettes and cigarette packs rejected by the machine's rejection port are manually removed, and then poured into the centrifugal turntable 100. As the turntable rotates, centrifugal force causes the cigarettes to scatter onto the spiral track 210 on the inner wall of the hopper 200, achieving the separation of individual cigarettes. The separated individual cigarettes continue to be conveyed upwards to the cigarette sorting mechanism 300. The cigarette sorting mechanism 300 compares the cigarettes based on the orientation of the filter end and the lighting end relative to the cigarette output direction, as well as the differences in cigarette color and length, and selects them accordingly. The information is then fed back to the controller, which drives the actuator of the cigarette sorting mechanism to push the defect-free cigarettes with different orientations into the corresponding funnels for collection. Cigarettes with appearance defects selected through graphic comparison are separated from defect-free cigarettes and can also be rejected, thereby achieving the technical purpose of orderly collection of cigarettes.

[0037] It should be noted that the image comparison techniques in the above embodiments are based on existing technologies, so the image comparison and classification techniques will not be further illustrated or described.

[0038] As an example, such as Figure 1 and Figure 2 As shown, the cigarette sorting mechanism 300 includes: a cigarette inlet track 310, a camera 320, a controller 330, a first rejection mechanism 340, and a second rejection mechanism 350. The cigarette inlet track 310 serves as a cigarette conveying channel, accommodating only a single cigarette as it lies flat. When the discharge port of the hopper reaches the end of the cigarette inlet track, the cigarette at the discharge port is conveyed from the lifting track to the camera 320. As an embodiment, the height of the inner side of the cigarette inlet track 310 (the side closer to the rotation axis of the centrifugal turntable 100) is slightly greater than the height of the outer side of the cigarette inlet track 310 (the side farther from the rotation axis of the centrifugal turntable 100), and it is driven by a belt conveyor structure or a commonly used power structure to achieve the technical purpose of conveying cigarettes.

[0039] The first rejection mechanism 340, the second rejection mechanism 350, and the camera 320 are electrically connected to the controller 330 respectively; the first rejection mechanism 340 and the second rejection mechanism 350 are respectively set on both sides of the smoke inlet track 310; the effective image recognition area of ​​the camera 320 is aligned with the smoke inlet track 310.

[0040] The camera transmits the image to the processor for recognition, and the processor selects the appearance quality defects of the cigarette, such as cigarette wrinkles, yellow spots, clamping ends, punctures, and uneven tipping paper, and identifies the cigarette with the above problems as defective cigarettes.

[0041] If the cigarette is a defective cigarette, neither the first nor the second rejection mechanism is triggered; if the cigarette is not defective and the direction of the filter end to the lit end of the cigarette is consistent with the transmission direction of the cigarette (hereinafter referred to as a filter end cigarette), the first rejection mechanism is triggered; if the direction of the filter end to the lit end of the cigarette is opposite to the transmission direction of the cigarette (hereinafter referred to as a lit end cigarette), the second rejection mechanism is triggered. The above technical solution of the present application can separate individual cigarettes to the inner wall track of the upper hopper based on the recovery amount of the cigarette, and transport the cigarette spirally upward according to the centrifugal force of the centrifugal disc.

[0042] In one use, when the filter end cigarette is selected, the pusher arm of the first rejection mechanism 340 on the right side of the cigarette inlet track 310 (based on the perspective) pushes the filter end cigarette into the left storage box; when the lit end cigarette is selected, the pusher arm of the second rejection mechanism 350 on the left side pushes the lit end cigarette into the right storage box. When the cigarette is identified as an appearance defect cigarette, the pusher arms of the two rejection mechanisms do not move, and the defective cigarette is continuously transported along the track until it falls off. Figure 1

[0043] As an example, the first rejection mechanism 340, the second rejection mechanism 350, and the lower part of the end position of the cigarette inlet track 310 are respectively provided with a cigarette storage box 360. After the storage box 360 is set, the recovered cigarette can be automatically separated and selected, and the classified cigarette is stored in the corresponding storage box.

[0044] Figure 3 The cigarette storage box 360 below the first rejection mechanism 340 and the second rejection mechanism 350 is shown.

[0045] Preferably, the upper part of the cigarette storage box 360 is provided with a funnel 361 with a trapezoidal longitudinal cross section.

[0046] Preferably, the falling end of the funnel 361 is only allowed to fall through a single cigarette, and the shape of the funnel changes from wide to narrow until only one cigarette is allowed to pass, so that the cigarette falling into the storage box cannot be disordered again.

[0047] As Figure 3 ​As shown, this embodiment further includes a track end baffle mechanism 370 based on the structural scheme disclosed in the above embodiments; the track end baffle mechanism 370 is electrically connected to the controller 330; the track end baffle mechanism 370 is located at the downstream end of the cigarette transmission direction of the smoke inlet track 310; the track end baffle mechanism 370 is triggered when the cigarette arrives at the baffle.

[0048] As one embodiment, the track end baffle mechanism 370 includes: a baffle with a lifting drive device and a position sensor; the lifting drive device and the position sensor are electrically connected to the controller 330. When the position sensor detects the arrival of a defective cigarette, it sends a position signal to the controller 330. The controller 330 controls the lifting drive device to lower the baffle, providing an outlet for the defective cigarette. After the defective cigarette falls, the controller 330 controls the lifting drive device to raise the baffle, preventing the cigarette from falling.

[0049] Preferably, the position sensor is a photoelectric sensor.

[0050] Preferably, the camera 320 and the controller 330 are integrated into a single smart camera.

[0051] Preferably, the smart camera is equipped with a fill light.

[0052] Preferred, such as Figure 1 As shown, a conical protrusion 120 is provided in the middle of the centrifugal turntable 100 to help disperse the cigarettes to the surrounding area.

[0053] The working principle of the above-described structure in this embodiment is as follows: Waste cigarettes and cigarette packs rejected by the machine's rejection port are manually removed of their waste materials and poured into a centrifugal turntable. The turntable has a conical protrusion in the center. As the turntable rotates, the cigarettes disperse in all directions and then adhere to a spiral track on the inner wall of the feeding hopper. This spiral track achieves the separation of individual cigarettes. The separated cigarettes are then conveyed upwards along the inlet track to the camera. The camera compares the color and length of the cigarettes at the filter tip and the lighting tip to select them and feeds the information back to the controller. The controller then drives the pusher arm of the corresponding rejection mechanism to push the cigarettes at the filter tip and the lighting tip into the corresponding trapezoidal funnels located on the left and right sides, respectively. As the trapezoidal funnels narrow, only one cigarette is allowed to slide down at a time. Finally, the cigarettes are stacked in the storage boxes on the left and right sides in a consistent and neat arrangement. In addition, the camera can also select cigarettes with appearance defects through graphic comparison, and transport them along the smoke inlet track to the end baffle mechanism at the end of the track for rejection.

[0054] In another embodiment of the present embodiment, the filter end cigarettes and the lit end cigarettes can also be pushed by the left and right cigarette pushing arms into the trapezoidal funnel respectively, and finally slide into the storage box through the trapezoidal funnel, wherein the appearance defective cigarettes continue to be conveyed upward along the cigarette conveying track to the track end baffle mechanism, and the cigarette baffle of the track end baffle mechanism falls off, and the defective cigarettes automatically fall off.

[0055] Although some specific embodiments of the present application have been described in detail by way of example with reference to the drawings, it is to be understood that the examples are for illustrative purposes only and are not to be construed as limiting the scope of the present application. It is to be understood that modifications can be made to the above embodiments without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
