Abstract
Description
A carton appearance inspection device Technical Field
[0001] This utility model relates to the field of visual inspection in the tobacco industry, and in particular to a carton appearance inspection device. Background Technology
[0002] With the development of automation in the tobacco industry, the speed of carton packaging machines in cigarette production is increasing, but corresponding packaging quality problems are also emerging. Equipment malfunctions, or missing or damaged cellophane, can easily lead to the cigarette cartons falling apart during transport, or the edges of the carton wrapper peeling off, causing blockages in the cigarette carton conveying system. Furthermore, if appearance defects such as dirt on the cartons and scratches on the cellophane caused during the packaging process are not inspected, defective cigarette cartons will enter the market, severely impacting the company's reputation. Therefore, appearance inspection of cigarette carton packaging is of paramount importance. Tobacco companies need to classify and statistically analyze carton appearance defects to improve cigarette quality. Therefore, both internal and external defects of the cellophane wrapper must be considered and categorized for identification.
[0003] Currently, most carton appearance inspections are performed after the oil sealing machine, which cannot simultaneously inspect the appearance of the carton inside the transparent paper and the appearance of the transparent paper. Moreover, most carton appearance inspection equipment on the market does not fully possess the capability for unobstructed inspection on all six sides. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carton appearance inspection device with good lighting effect and the ability to inspect the carton appearance inside the transparent paper and the carton appearance outside the transparent paper from all six sides without obstruction.

[0015] 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 constitute any limitation thereof.
[0016] Referring to Figures 1 to 3, this embodiment provides a carton appearance inspection device, including a smoke storage device 1, a smoke pushing device 2, a first inspection station 3, a flipping device 4, a second inspection station 5, and a base plate 8. After inspecting the carton at the first inspection station 3, the carton is flipped by the flipping device 4 and enters the second inspection station 5 for six-sided inspection. Each planar image-taking surface at the first inspection station 3 and the second inspection station 5 is illuminated by a planar shadowless light source, and each vertical image-taking surface is illuminated by a linear light source. Furthermore, the inspection device also includes a rejection device 6 and a slide 7. Cartons that fail the inspection are rejected at the rejection device 6, and the rejected cartons are collected via the slide 7. Qualified cartons proceed to the next process via a conveyor belt.
[0017] Referring to Figure 2, the first inspection station 3 includes six camera components. The first camera component 101, the second camera component 102, the third camera component 103, and the fourth camera component 104 are fixed to the base plate 8 by the first bracket 111. The first planar shadowless light source 110 is fixed to the first support plate 107. The fifth camera component 105 and the sixth camera component 106 are fixed to the first support plate 107 by the third bracket 115. The first support plate 107 is fixed to the base plate 8 by the first support seat 109 and the cantilever support 108. The first linear light source 113 and the second linear light source 114 are fixed to the base plate 8 by the first mounting plate 112.
[0018] Referring to Figure 3, the second inspection station 5 includes four camera components: the ninth camera component 203 and the tenth camera component 204 are fixed to the second support base 208 by the second bracket 209; the second planar shadowless light source 205 is fixed to the second support plate 211; the seventh camera component 201 and the eighth camera component 202 are fixed to the second support plate 211 by the fourth bracket 210; the second support plate 211 is fixed to the base plate 8 by the second support base 208; and the third linear light source 206 and the fourth linear light source 207 are fixed to the base plate 8 by the second mounting plate 211.
[0019] The working principle is as follows: After the carton 9 comes out of the smoke storage device, it is pushed to the flipping device 4 by the smoke pushing device 2. When it passes the first detection station 3, it is illuminated by the first planar shadowless light source 110, the first linear light source 113 and the second linear light source 114. The fifth camera assembly 105 and the sixth camera assembly 106 perform imaging detection on the top of the carton, the first camera assembly 101 and the second camera assembly 102 perform imaging detection on the front of the carton, and the third camera assembly 103 and the fourth camera assembly 104 perform imaging detection on the back of the carton. After the carton enters the flipping device 4 and is flipped 180°, the bottom surface faces upward and the top surface contacts the conveyor belt. It moves towards the removal device 6 by the conveyor belt. When it passes the second detection station 5, it is illuminated by the second planar shadowless light source 205, the third linear light source 206 and the fourth linear light source 207. The seventh camera assembly 201 and the eighth camera assembly 202 image and detect the bottom surface of the carton, the ninth camera assembly 203 image and detects the left side of the carton, and the tenth camera assembly 204 image and detects the right side of the carton.
[0020] The carton appearance inspection device in this embodiment uses a planar shadowless light source for illumination on each planar imaging surface and a linear light source for illumination on each vertical imaging surface. This provides good lighting and allows for the simultaneous inspection of both the appearance of the carton inside the transparent paper and the appearance of the transparent paper itself. The use of multiple cameras further enhances the accuracy of the inspection.
