Description

Technical Field

[0001] The utility model relates to cigar packaging equipment, and more specifically, to a cigar packaging tube appearance detection device. Background Art

[0002] Cigars are a type of tobacco product made from dried and fermented tobacco. When smoking, one end is ignited and the other end is inhaled to produce smoke. Cigars are loved by smokers for their unique taste. In order to facilitate storage, transportation, subsequent fermentation and sale, cigarette companies will package cigars after making them into finished products. Common packaging methods are mainly box packaging and single-piece packaging. For example, the Chinese utility model patent document CN221554698U discloses an umbrella-type pull-out cigar box, which uses a box body as a container and fixes the cigars through partition grooves to achieve packaging of cigars. Single-piece packaging mainly adopts tube packaging, that is, the cigars are packaged in a packaging tube. The packaging tube is a hollow tube with an opening at one end and a closed end at the other end. The open end is sealed with a cover plug, and the cover plug and the packaging tube are connected. Typically, threaded connections or snap fasteners are used. High-end cigars are often packaged in individual tubes. This packaging effectively protects the cigar wrapper and foot from physical damage, provides a better fermentation environment, prevents moisture evaporation, helps maintain a long-lasting aroma, and enhances the quality of the cigar. Individually packaged cigars are also more portable and can be easily placed in a pocket, making them suitable for on-the-go smoking. Existing cigar packaging equipment uses an intermittent conveyor belt. An automatic blanking mechanism places the cigars and packaging tubes on the conveyor belt. A tube-pushing mechanism then pushes the packaging tube into the tube. A cap-feeding mechanism then places the cap on the conveyor belt. Finally, a capping mechanism secures the cap to the tube, completing the packaging of the individual cigars. After the tube and cap are secured, a visual inspection device is required to inspect the finished product's appearance. While this device addresses the visual inspection issue, it increases production costs by adding additional steps. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] like Figure 1 As shown: A cigar packaging tube appearance inspection device includes a roller conveyor 1. The upper part of the roller conveyor 1 is provided with a cap plug unloading mechanism 2 and a cap pressing rotating device from left to right. The conveyor belt of the roller conveyor 1 uses intermittent motion to convey materials. The roller conveyor 1 includes a bracket 101, a chain, a roller 102, and a drive motor. The chain is rotatably mounted on the bracket 101. A plurality of rollers 102 are evenly and longitudinally fixedly mounted on the chain. The chain and the rollers 102 are combined to form a conveyor belt. Two adjacent A longitudinal limit groove 103 is formed between the rollers 102. The chain is rotated by the driving motor, and the chain rotation drives the rollers 102 to move. The longitudinal limit groove 103 refers to the transmission direction of the conveyor belt of the roller conveyor 1 as the transverse direction, and the direction at the same horizontal plane as the conveyor belt and perpendicular to the transverse direction as the longitudinal direction, that is, each limit groove 103 is arranged on the conveyor belt plane perpendicular to the transmission direction of the conveyor belt; the inlet end of the roller conveyor 1 is also provided with a transition groove 3, which is connected to the front-end mechanism of the single cigar packaging equipment.

[0020] The capping and rotating device includes a top cap mechanism 4 and a rotating mechanism 5, which are axially aligned and respectively installed on the brackets 101 on both sides of the conveyor belt. The top cap mechanism 4 is located on one side of the cap plug unloading mechanism 2; the top cap mechanism 4 is a telescopic cylinder, and the rotating mechanism 5 is a rotating cylinder or a rotating motor; when the packaging tube and the cap plug containing cigars are conveyed between the top cap mechanism 4 and the rotating mechanism 5, the cylinder shaft of the top cap mechanism 4 extends and pushes the cap plug toward the rotating mechanism 5 along the limiting groove 103. In the process of the cap plug being pushed, the cap plug pushes the packaging tube to move axially toward the rotating mechanism 5 until the end of the packaging tube abuts against the rotating axis of the rotating mechanism 5. The top cap mechanism 4 and the rotating mechanism 5 cooperate to axially clamp and squeeze the two ends of the packaging tube and the cap plug, so that the cap plug is clamped on the packaging tube, and the assembly of the cap plug and the packaging tube is completed.

[0021] like Figure 2 As shown: the front end of the cylinder shaft of the top cover mechanism 4 is also rotatably installed with a push head 401, and the front end of the push head 401 has an arc-shaped groove 402, which is adapted to the top of the plug. The front end of the rotating shaft of the rotating mechanism 5 is also provided with a groove adapted to the bottom of the packaging tube. The arc-shaped groove 402 on the push head 401 and the groove at the front end of the rotating shaft of the rotating mechanism 5 are used to axially limit the plug and the packaging tube to avoid inaccurate docking when the plug and the packaging tube are clamped; two tapered roller bearings 403 are fixedly installed on the cylinder shaft of the top cover mechanism 4, and the two tapered roller bearings 403 are installed opposite to each other. The push head 401 is sleeved on the outer walls of the two tapered roller bearings 403, and the tapered roller bearings 403 are used to bear the thrust while realizing the rotatability of the push head 401, so that the packaging tube can rotate smoothly during visual inspection.

[0022] like Figure 1 As shown: the roller conveyor 1 is also provided with a visual inspection mechanism, which is installed on the roller conveyor 1 through a gantry 601. The visual inspection mechanism includes a linear array industrial camera 6, a lens, and a light source. The linear array industrial camera 6, the lens, and the light source are fixedly installed on the gantry 601. The linear array industrial camera 6, the lens, and the light source are connected to the control terminal signal. The working end of the linear array industrial camera 6 corresponds to the capping rotating device. In actual production, a ring mark (referred to as the ring mark) is also affixed to the packaging tube. After the packaging tube and the cap are clamped together, the rotating mechanism 5 drives the packaging tube to rotate. The linear array industrial camera 6 collects images of the ring mark outside the packaging tube and the packaging tube to check for defects such as missing ring marks and damaged packaging tubes, and analyzes whether the product has defects through machine vision algorithms.

[0023] A rejection mechanism 7 is also provided at the rear of the capping rotating device on the roller conveyor 1. The rejection mechanism 7 is a telescopic cylinder and is connected to the control terminal signal. The rejection mechanism 7 also includes a waste collection box 701 arranged on the other side of the roller conveyor 1, and a slide 702 connected to the waste collection box 701. The slide 702 is axially aligned with the telescopic cylinder; when the linear array industrial camera 6 detects that the cap plug or packaging tube is damaged or the ring label is missing, the control terminal locates the defective product according to the running position. When the defective product is conveyed to the rejection mechanism 7, the control terminal controls the cylinder shaft of the rejection mechanism 7 to extend, and pushes the defective product from the limit groove 103 through the slide 702 into the waste collection box 701.

[0024] Specific usage method: Before visual inspection of cigars, the front-end single-piece cigar packaging equipment puts the cigars into the packaging tube. The packaging tube containing cigars slides from the transition slot 3 to the limit slot 103 on the roller conveyor 1. The roller conveyor 1 drives the packaging tube containing cigars to intermittently move to the plug unloading mechanism 2. The plug unloading mechanism 2 puts the plug into the limit slot 103 on the open end of the packaging tube. The roller conveyor 1 continues to drive the packaging tube and the plug to intermittently move to the capping rotating device. The cylinder shaft of the top cover mechanism 4 extends and pushes the plug along the limit slot 103 to the rotating mechanism 5. In the process of the plug being pushed, the plug pushes the packaging tube to move axially toward the rotating mechanism 5 until the packaging is finished. The bottom of the tube abuts against the rotating mechanism 5, and the top cover mechanism 4 and the rotating mechanism 5 axially clamp and squeeze the two ends of the packaging tube and the plug so that the plug is connected to the packaging tube. After the plug and the packaging tube are assembled, the rotating mechanism 5 drives the packaging tube to rotate in a circle, and the linear array industrial camera 6 captures images of the ring label outside the packaging tube and the packaging tube, and analyzes whether the product has defects through the machine vision algorithm. After the inspection is completed, the axis of the top cover mechanism 4 shrinks, and the finished product falls into the limit groove 103. The roller conveyor 1 continues to drive the finished product to move toward the discharge port. Qualified finished products are transported to the subsequent packaging process, and unqualified finished products are sent to the rejection mechanism 7. The rejection mechanism 7 pushes the unqualified products into the waste collection box 701.
