Description

Technical Field

[0001] This utility model relates to the field of finished cigarette sampling and testing, and in particular to a device for the layering and visual inspection of cigarette packs after unpacking. Background Technology

[0002] In the modern tobacco industry, relatively stable and reliable quality inspection methods have been established at various stages of cigarette production. Machines and manual labor each perform their specific functions, bearing the heavy responsibility of quality control. However, in the context of modernization and high speed, some manual inspection methods suffer from inefficiency, subjective testing, and high labor intensity, causing problems that hinder upstream and downstream production. Currently, before packing cigarette cartons, a final, consumer-facing inspection is required: random quality checks of the inner cigarette packs after packaging. This process currently relies heavily on manual inspection, requiring the manual removal of the outer packaging and the extraction of the inner cigarette packs for specific manual inspection.

[0003] Currently, the unpacking and inspection of cigarette packs have been implemented, but many problems still exist. Due to the adhesion between the oil seal paper on the outer surface of the cigarette pack and the single-intervention process during layering and repackaging, the layering and repackaging work cannot be completed well, resulting in some failures. In addition, in terms of visual inspection, true six-sided inspection of the cigarette pack has not been achieved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a simple device for layering and visually inspecting cigarette packs after unpacking double-layer cigarette packs. This device can also perform six-sided inspection of the cigarette packs.

[0005] The technical solution of the cigarette pack layering and visual inspection equipment provided by this utility model is as follows:

[0006] The device includes a layered lifting device for cigarette packs (1), a longitudinal conveying device for cigarette packs (2), and a transverse conveying device for flipping cigarette packs (3). The layered lifting device for cigarette packs (1) includes a cigarette pack bin (10), a vertical movement mechanism (11), a fixed support (12), and a horizontal movement mechanism (13). The fixed support (12) is fixed in place. The vertical movement mechanism (11), the horizontal movement mechanism (13), and the cigarette pack bin (10) are installed on the fixed support (12). An inlet layered guide is provided inside the cigarette pack bin (10). The plate (14) and the inlet layer guide plate (14) are located on the upper layer of the double-layer cigarette pack (4). When the double-layer cigarette pack (4) is pushed into the cigarette pack warehouse (10) by the upstream cigarette pack unpacking equipment, the bottom layer cigarette pack (4) moves in a straight line along the pushing direction, and the upper layer cigarette pack (4) is guided by the inlet layer guide plate (14) to realize the positional shift of the upper and lower layers. Then, the cigarette pack is sequentially passed through the cigarette pack sub-packing longitudinal conveying device (2) and the cigarette pack flipping transverse conveying device (3) to complete the layering and packaging of the cigarette pack and perform six-sided visual inspection.

[0007] Furthermore, after the double-layer cigarette pack (4) is fully inserted into the cigarette pack chamber (10), the up-down movement mechanism (11) lowers the cigarette pack chamber (10) with it. After it descends to the bottom of its stroke, the horizontal movement mechanism (13) extends horizontally and contacts the lower layer of the double-layer cigarette pack (4), pushing the lower cigarette pack (4) out of the cigarette pack layer outlet (15). After the horizontal movement mechanism (13) retracts, the upper cigarette pack (4) descends to the lower layer by gravity and can be pushed out on the second push.

[0008] Furthermore, the longitudinal conveying device (2) for cigarette pack subpackaging includes a single-layer cigarette pack inlet conveying section (20), a single-layer cigarette pack subpackaging conveying section (21), and a first cigarette pack three-sided visual inspection group (22). The single-layer cigarette pack inlet conveying section (20) is connected to the single-layer cigarette pack subpackaging conveying section (21), and the first cigarette pack three-sided visual inspection group (22) is set on the single-layer cigarette pack subpackaging conveying section (21).

[0009] Furthermore, the single-layer cigarette pack access conveying section (20) includes a first conveyor belt (200), a first guide frame (201), a first support structure (202), and a cigarette pack presence / absence detection sensor (203). The first support structure (202) is fixed, and the first conveyor belt (200), the first guide frame (201), and the cigarette pack presence / absence detection sensor (203) are all fixed on the first support structure (202). The single-layer cigarette pack access conveying section (20) is used for the access and forward conveying of the single-layer cigarette pack (4) pushed out by the cigarette pack layer lifting device (1). When the cigarette pack (4) is pushed in, the presence / absence of the cigarette pack (4) is judged by the cigarette pack presence / absence detection sensor (203). When no cigarette pack (4) is detected, it can be pushed in and conveyed after being pushed in. The first guide frame (201) is used for guiding the cigarette pack (4), and the first conveyor belt (200) is used for forward conveying of the cigarette pack (4).

[0010] Furthermore, the single-layer cigarette pack sub-packaging and conveying section (21) includes a second conveyor belt (210), a second guide frame (211), a second support structure (212), and a differential structure. The second support structure (212) is fixed, and the second conveyor belt (210), the second guide frame (211), and the differential structure are all fixed on the second support structure (212). The single-layer cigarette pack sub-packaging and conveying section (21) is used for the sub-packaging and forward movement of the incoming single-layer cigarette packs (4). The second conveyor belt (210) is used for the forward conveying of the cigarette packs (4), and the second guide frame (211) is used for the forward conveying of the cigarette packs (4). The guide for the conveying process of the pack (4) is a differential structure used for the sub-packing of single-layer cigarette packs (4). The differential structure includes a large and small pulley group (213), a first power source (214), and a differential roller group (215). The small pulley in the large and small pulley group (213) provides power to the single-layer cigarette pack sub-packing conveying section (21), and the large pulley provides power to the single-layer cigarette pack access conveying section (20). The differential speed between the front and rear conveying sections is achieved through the speed ratio of the large and small pulleys, thereby realizing the sub-packing of cigarette packs (4). The transition section between the single-layer cigarette pack access conveying section (20) and the single-layer cigarette pack sub-packing conveying section (21) has a height difference.

[0011] Furthermore, the first cigarette pack three-sided visual inspection group (22) includes a camera lens group (220), a top light source (221), an auxiliary light source (222), a bottom diffuser (223), a bottom trigger sensor (224), and a support (225). The support (225) serves to fix the cigarette pack. The camera lens group (220) is set on the top and the two sides of the cigarette pack (4) in the forward direction and is responsible for taking pictures. The top light source (221) and the bottom diffuser (223) are used to provide illumination for the three sides of the cigarette pack (4) to be inspected. The diffuser will reflect the light from the top light source (221) to the two sides of the cigarette pack (4) to be inspected. The auxiliary light source (222) is used to illuminate the cellophane defects on the top surface of the cigarette pack (4). The trigger of the camera lens group (220) is set with a certain delay after the first trigger. The bottom trigger sensor (224) is used to detect that the camera lens group (220) provides a trigger signal after the cigarette pack (4) reaches the picture position.

[0012] Furthermore, the cigarette pack flipping and transverse conveying device (3) includes a flipping and pushing mechanism (30), a cigarette pack transverse conveying device (31), a second cigarette pack three-sided visual inspection group (32), and a cigarette pack outlet and rejection device (33). The flipping and pushing mechanism (30) is connected to the cigarette pack transverse conveying device (31) and is used to flip the cigarette pack. The second cigarette pack three-sided visual inspection group (32) is set on the cigarette pack transverse conveying device (31), and the cigarette pack outlet and rejection device (33) is located at the end of the cigarette pack flipping and transverse conveying device (3).

[0013] Furthermore, the flipping and pushing mechanism (30) includes a timing belt with a stop (300), a fixed frame (301), a second power source (302), a cigarette pack arrival sensor (303), and a flipping slide (304). The fixed frame (301) is used to fix the entire mechanism. The second power source (302) provides motion power to the timing belt with the stop. When the cigarette pack (4) reaches the end position, the cigarette pack arrival sensor (303) detects that it is in position. The second power source (302) drives the timing belt with the stop to perform intermittent motion, pushing the cigarette pack into the flipping slide (304). The cigarette pack (4) reaches the lower cigarette pack transverse conveying device (31) through the arc-shaped slide and completes the flipping of the cigarette pack (4), preparing for the subsequent bottom mapping of the cigarette pack (4).

[0014] Furthermore, the transverse conveying device (31) for cigarette packs is a conveyor belt that includes a guide frame.

[0015] Furthermore, the structure of the second cigarette pack three-sided visual detection group (32) is the same as that of the first cigarette pack three-sided visual detection group (22), and it is used to capture images of the other three sides of the cigarette pack (4).

[0016] Furthermore, the cigarette pack outlet and rejection device (33) includes a rejection guide port (330), a rejection cigarette pack sensor (331), a rejection solenoid valve (332), and a rejection nozzle (333). When a defective cigarette pack (4) reaches a predetermined position, the rejection cigarette pack sensor (331) detects the cigarette pack (4) and activates the rejection solenoid valve (332). The cigarette pack (4) is blown to the rejection guide port (330) through the nozzle connected to the solenoid valve, and the qualified cigarette pack (4) flows into the downstream equipment.

[0017] The implementation of this utility model has the following technical effects:

[0018] This invention relates to a device for layering and visually inspecting cigarette packs after unpacking. It involves multiple interventions in the double-layered cigarette packs after unpacking (initial intervention by the inlet layering guide plate, and subsequent intervention by the horizontal movement mechanism). The smaller, layered packs also undergo multiple interventions (accurate layering through speed and height differences), thus achieving better layering and repackaging results and solving the problem of high failure rates during the layering and repackaging process. Through structural improvements, multiple interventions are achieved, resulting in excellent performance in layering double-layered cigarette packs and repackaging single-layered cigarette packs.

[0031] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention and do not limit it in any way.

[0032] See Figure 1 As shown in the figure, this embodiment provides a cigarette pack layering and visual inspection device after unpacking, including a cigarette pack layering lifting device 1, a cigarette pack longitudinal conveying device 2, and a cigarette pack flipping transverse conveying device 3. See [link to documentation]. Figure 2 and Figure 3As shown, the cigarette pack layer lifting device 1 includes a cigarette pack compartment 10, a vertical movement mechanism 11, a fixed support 12, and a horizontal movement mechanism 13. The fixed support 12 is fixed in place, and the vertical movement mechanism 11, the horizontal movement mechanism 13, and the cigarette pack compartment 10 are installed on the fixed support 12. An inlet layering guide plate 14 is set inside the cigarette pack compartment 10. The inlet layering guide plate 14 is located on the upper layer of the double-layer cigarette pack 4. When the double-layer cigarette pack 4 is pushed into the cigarette pack compartment 10 by the upstream cigarette pack unpacking equipment, the bottom layer cigarette pack 4 moves in a straight line along the pushing direction, and the upper layer cigarette pack 4 makes a compound movement under the guidance of the inlet layering guide plate 14, thereby achieving the first layering intervention and realizing the positional misalignment of the upper and lower layers to help with subsequent layering. Then, the cigarette packs are sequentially conveyed by the cigarette pack longitudinal conveying device 2 and the cigarette pack flipping transverse conveying device 3 to complete the layering and packaging of the cigarette packs and perform six-sided visual inspection. After the double-layer cigarette pack 4 is fully inserted into the cigarette pack chamber 10, the vertical movement mechanism 11 moves the cigarette pack chamber 10 downward. After descending to the bottom of its stroke, the horizontal movement mechanism 13 extends horizontally. The horizontal movement mechanism 13 contacts the lower layer of the double-layer cigarette pack 4, thereby pushing the lower layer of cigarette pack 4 out of the cigarette pack layering outlet 15. When the horizontal movement mechanism 13 retracts, the upper layer of cigarette pack 4 initially descends to the lower layer by gravity. It can be pushed out on the second push. This push action realizes the second layering work. The two layering effects can better solve the problem of the double-layer cigarette pack 4 not sticking together. Figures 1 to 3 The image shows two tobacco pack compartments 10. The upper tobacco pack compartment indicates the state at the entrance, and the lower tobacco pack compartment indicates the state of descent. In reality, there is only one tobacco pack compartment 10.

[0033] See Figure 4 As shown, the longitudinal conveying device 2 for cigarette pack sub-packaging includes a single-layer cigarette pack inlet conveying section 20, a single-layer cigarette pack sub-packaging conveying section 21, and a first cigarette pack three-sided visual inspection group 22. The single-layer cigarette pack inlet conveying section 20 is connected to the single-layer cigarette pack sub-packaging conveying section 21, and the first cigarette pack three-sided visual inspection group 22 is installed on the single-layer cigarette pack sub-packaging conveying section 21. See also... Figure 5 As shown, the single-layer cigarette pack inlet conveyor section 20 includes a first conveyor belt 200, a first guide frame 201, a first support structure 202, and a cigarette pack presence / absence detection sensor 203. The first support structure 202 is fixed, and the first conveyor belt 200, the first guide frame 201, and the cigarette pack presence / absence detection sensor 203 are all fixed on the first support structure 202. The single-layer cigarette pack inlet conveyor section 20 is mainly used for the inlet and forward conveying of the single-layer cigarette packs 4 pushed out by the cigarette pack layer lifting device 1. When the cigarette pack 4 is pushed in, the presence / absence of the cigarette pack 4 is determined by the cigarette pack presence / absence detection sensor 203. When no cigarette pack 4 is detected, it can be pushed in and then conveyed. The first guide frame 201 is used for guiding the cigarette pack 4, and the first conveyor belt 200 is used for forward conveying of the cigarette pack 4. See also Figure 6As shown, the single-layer cigarette pack sub-packaging and conveying section 21 includes a second conveyor belt 210, a second guide frame 211, a second support structure 212, and a differential structure. The second support structure 212 is fixed, and the second conveyor belt 210, the second guide frame 211, and the differential structure are all fixed on the second support structure 212. The single-layer cigarette pack sub-packaging and conveying section 21 is used for the sub-packaging and forward movement of the incoming single-layer cigarette packs 4. The second conveyor belt 210 is used for the forward conveying of the cigarette packs 4, and the second guide frame 211 is used for the conveying of the cigarette packs 4. The process guides the distribution of single-layer cigarette packs 4 using a differential speed structure. This structure includes a large and small pulley group 213, a first power source 214, and a differential roller group 215. The small pulley in the large and small pulley group 213 provides power to the single-layer cigarette pack distribution conveyor section 21, while the large pulley provides power to the single-layer cigarette pack inlet conveyor section 20. The speed difference between the front and rear conveyor sections is achieved through the speed ratio of the large and small pulleys, thus enabling the distribution of cigarette packs 4. The transition section between the single-layer cigarette pack inlet conveyor section 20 and the single-layer cigarette pack distribution conveyor section 21 has a height difference. The differential roller provides a speed difference for the initial distribution between the single-layer cigarette pack inlet conveyor section 20 and the single-layer cigarette pack distribution conveyor section 21, and the speed difference at both points assists in the distribution process. Furthermore, the height difference between the single-layer cigarette pack inlet conveyor section 20 and the single-layer cigarette pack distribution conveyor section 21 provides space for the continuous cigarette packs 4 to move around using gravity. (See also...) Figure 7 As shown, the first three-sided visual inspection group 22 of the cigarette pack includes a camera lens group 220, a top light source 221, an auxiliary light source 222, a bottom diffuser 223, a bottom trigger sensor 224, and a support 225. The support 225 serves to fix the cigarette pack. The camera lens group 220 is set on the top and the two sides of the cigarette pack 4 in the forward direction and is responsible for taking pictures. The top light source 221 and the bottom diffuser 223 are used to provide illumination for the three sides of the cigarette pack 4 that need to be inspected. The diffuser reflects the light from the top light source 221 to the two sides of the cigarette pack 4 that need to be inspected. The auxiliary light source 222 is used to illuminate the defects of the cellophane on the top surface of the cigarette pack 4. The triggering of the camera lens group 220 is set with a certain delay after the first triggering. The bottom trigger sensor 224 is used to detect that the camera lens group 220 provides a trigger signal after the cigarette pack 4 reaches the picture position.

[0034] See Figure 8 As shown, the cigarette pack turning and transverse conveying device 3 includes a turning and pushing mechanism 30, a cigarette pack transverse conveying device 31, a second cigarette pack three-sided visual inspection group 32, and a cigarette pack outlet and rejection device 33. The turning and pushing mechanism 30 is connected to the cigarette pack transverse conveying device 31 and is used to turn the cigarette packs over. The second cigarette pack three-sided visual inspection group 32 is installed on the cigarette pack transverse conveying device 31, and the cigarette pack outlet and rejection device 33 is located at the end of the cigarette pack turning and transverse conveying device 3. See also Figure 9As shown, the flipping and pushing mechanism 30 includes a timing belt with stops 300, a fixing frame 301, a second power source 302, a cigarette pack arrival sensor 303, and a flipping slide 304. The fixing frame 301 is used to fix the entire mechanism. The second power source 302 provides motion power to the timing belt with stops. When the cigarette pack 4 reaches the end position, the cigarette pack arrival sensor 303 detects its position. The second power source 302 drives the timing belt with stops 300 to move intermittently, pushing the cigarette pack into the flipping slide 304. The cigarette pack 4 passes through the arc-shaped slide to the lower cigarette pack transverse conveyor 31, completing the flipping operation of the cigarette pack 4, thus preparing for subsequent bottom image acquisition of the cigarette pack 4. The transverse conveyor 31 is a conveyor belt including a guide frame. The structure of the second cigarette pack three-sided visual inspection group 32 is the same as that of the first cigarette pack three-sided visual inspection group 22, used to capture images of the other three sides of the cigarette pack 4. The specific structure will not be described in detail. See [link to documentation]. Figure 10 As shown, the cigarette pack outlet and rejection device 33 includes a rejection guide port 330, a rejection cigarette pack sensor 331, a rejection solenoid valve 332, and a rejection nozzle 333. When the defective cigarette pack 4 reaches the predetermined position, the rejection cigarette pack sensor 331 detects the cigarette pack 4 and activates the rejection solenoid valve 332. The cigarette pack 4 is blown to the rejection guide port 330 through the nozzle connected to the solenoid valve, and the qualified cigarette pack 4 flows into the downstream equipment.

[0035] Because of the adhesive force on the contact surface of the cigarette pack after the sealing paper, a single direct push cannot effectively complete the layering and packaging process when the adhesive force is strong. This invention addresses these issues by implementing multiple interventions after the pack of cigarettes is opened, including an initial intervention by the inlet layering guide plate and a horizontal movement mechanism. The smaller packs after layering also undergo multiple interventions, including differential speed packaging and height difference packaging, to achieve accurate packaging. This results in better layering and packaging, solving the problem of high failure rates during the layering and packaging process. Through structural improvements and multiple interventions, it achieves excellent results in both layering double-layer cigarette packs and packaging single-layer cigarette packs.

[0036] The visual appearance inspection method of this utility model avoids the jigsaw puzzle method required in the visual inspection of cigarette packs. It uses three cameras to first inspect three sides of the cigarette pack, and then flips the cigarette pack over to inspect the other three sides. This avoids the jigsaw puzzle inspection method in the existing inspection process and truly achieves complete inspection of all six sides of the cigarette pack.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
