[0003] Usually, the inspection of the box cover and the cover insertion gap mainly relies on manual inspection of the box cover, and unqualified packaging boxes are rejected, and the qualified boxes are placed on the conveyor belt and transported to the next process.

[0004] However, the manual inspection method wastes human resources, and an automatic inspection and rejection device is needed to save human resources.

[0005] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a cartoning machine cover detection and rejection device to solve the shortcomings of the prior art. Utility Model Content

[0006] The purpose of the utility model is to avoid the deficiencies of the prior art and to provide a cartoning machine cover detection and rejection device, which performs vertical laser detection on the cover of the packaging box through a laser detector. When it is detected that the cover plate and the cover insertion gap are not inserted into the interior of the box body, the packaging box body falling from the cartoning machine conveyor belt is introduced into the interior of the rejection collection slot through the sorting and rejection mechanism, thereby realizing automatic detection and rejection of the cartoning machine cover and saving human resources.

[0007] The above-mentioned purpose of the utility model is achieved through the following technical means.

[0033] The utility model is further described in conjunction with the following embodiments.

[0034] Example 1.

[0035] like Figure 1-4 As shown, a cover detection and rejection device for a cartoning machine comprises two L-shaped positioning frames 1, the L-shaped positioning frames 1 are fixedly mounted on both sides of the end of a cartoning machine conveyor belt 2, a plurality of packaging boxes 3 are placed on the cartoning machine conveyor belt 2, a laser detector 4 is fixedly mounted on the top of the L-shaped positioning frame 1, and a sorting and rejection mechanism is fixedly mounted below the end of the cartoning machine conveyor belt 2.

[0036] The present application is used to perform cover detection on the cartoning machine of the packaging box 3. First, the laser detector 4 is fixed by the L-shaped positioning frame 1. The detection distance of the laser detector 4 only needs to be from the top of the L-shaped positioning frame 1 to the cartoning machine conveyor belt 2. When the cover plate 10 and the cover insertion gap piece of the packaging box 3 are not inserted into the interior of the box body, the cover plate 10 and the cover insertion gap piece can fall into the inside of the detection range, and an unqualified signal can be issued, and then the unqualified packaging box 3 is introduced into the rejection collection slot 7 for separate collection through the sorting and rejection mechanism.

[0037] The sorting and rejecting mechanism includes a supporting platform 5, a finished product collecting trough 6 is fixedly installed at any end of the supporting platform 5, a rejecting collecting trough 7 is fixedly installed at the end of the finished product collecting trough 6 away from the supporting platform 5, the finished product collecting trough 6 is located below the end of the cartoning machine conveyor belt 2, and two movable slideways 8 are jointly provided on the supporting platform 5 and the finished product collecting trough 6, a blanking ramp 9 is slidably installed on the movable slide 8, and the lower end of the blanking ramp 9 faces the end of the movable slide 8 close to the rejecting collecting trough 7.

[0038] The sorting and rejection mechanism installs the blanking ramp 9 on the supporting platform 5 and the finished product collection trough 6 through sliding. After the packaging box 3 is boxed and sealed by the cartoning machine, the qualified products can directly fall into the interior of the finished product collection trough 6 through the cartoning machine conveyor belt 2. When the laser detector 4 sends out an unqualified signal, the blanking ramp 9 can be pushed to slide on the moving slide 8 and slide to the top of the finished product collection trough 6, and the unqualified packaging box 3 can be introduced into the interior of the rejection collection trough 7.

[0039] The light beam of the laser detector 4 passes through the L-shaped positioning frame 1 , the width of the cover plate 10 of the packaging box 3 is D1 , and the horizontal distance between the light beam of the laser detector 4 and the cover plate 10 of the packaging box 3 is D2 , and D2 satisfies 0<D2≤D1.

[0040] The beam of the laser detector 4 detects a vertical line. When the cover 10 and the cover insertion gap are not inserted into the box body, the range of the cover 10 and the cover insertion gap is within a distance D1 extending outward from both ends of the packaging box 3. When D2 satisfies 0<D2≤D1, it can be detected that the cover 10 and the cover insertion gap are not inserted into the box body. D2=1 / 2D1 is the best position, which ensures the detection of unqualified capping and avoids misjudgment.

[0041] A driving cylinder 11 is fixedly mounted on the supporting platform 5 , and an output end of the driving cylinder 11 is fixedly connected to the blanking ramp 9 .

[0042] The blanking ramp 9 is pushed to move to the top of the finished product collection tank 6 by the output of the driving cylinder 11, and the unqualified products are introduced into the rejection collection tank 7. The driving cylinder 11 receives the signal of the laser detector 4 for driving.

[0043] A protective side plate 12 is fixedly mounted on the blanking ramp 9 .

[0044] The protective side plate 12 can prevent the packaging box 3 from sliding to the outside.

[0045] The vertical projection area of ​​the blanking ramp 9 is the same as the vertical projection area of ​​the finished product collecting trough 6 .

[0046] The blanking inclined platform 9 completely covers the top of the finished product collecting tank 6 , and introduces the unqualified packaging boxes 3 into the rejection collecting tank 7 .

[0047] The utility model performs vertical laser detection on the sealing part of the packaging box 3 through the laser detector 4. When it is detected that the cover plate 10 and the cover insertion gap piece are not inserted into the interior of the box body, the packaging box 3 falling from the cartoning machine conveyor belt 2 is introduced into the interior of the rejection collection slot 7 through the sorting and rejection mechanism, thereby realizing automatic detection and rejection of the sealing part of the cartoning machine and saving human resources.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
