Description

Technical Field

[0001] This invention belongs to the field of food defect detection and identification technology, and in particular relates to a flipping conveyor. Background Technology

[0002] Small-packaged snack foods often require testing after processing and packaging. Substandard products are discarded, and the qualified products are then boxed, packaged, and transported. The detection of defects in snack foods is crucial to food safety. However, the small size and diverse shapes of these snack products present significant challenges for testing.

[0003] Existing small package inspection methods typically involve manual or mechanical inspection. Manual inspection is inefficient and prone to omissions, while existing mechanical inspection methods mostly only perform single-sided scanning, resulting in incomplete inspection and significantly reducing inspection efficiency. Summary of the Invention

[0006] Preferably, the upper conveyor is higher than the lower conveyor, and both the upper and lower conveyors are driven by motors.

[0007] Preferably, both the upper and lower conveyors are fitted with supports, and the supports are fitted with external protective covers.

[0008] Preferably, the control panel is located on the top surface of the outer cover.

[0009] Preferably, the rack is arranged in a cabinet shape.

[0010] Preferably, a visual light source device is provided directly below the front and back visual recognition lenses.

[0011] The present invention has at least the following beneficial effects:

[0012] This invention provides a flipping conveyor that can conveniently perform visual identification and inspection of the front and back of small packaged snack foods, remove defective products, greatly improve efficiency, and greatly facilitate use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This invention provides a technical solution: a tilting conveyor, including a frame 3, with an upper conveyor 4 and a lower conveyor 7 spaced apart on the top surface of the frame 3. Specifically, the upper conveyor 4 and the lower conveyor 7 are fixed to the frame 3 by a fixed frame. A tilting curved surface 9 is provided between the upper conveyor 4 and the lower conveyor 7. The tilting curved surface 9 is sleeve-shaped and has a spiral intermediate curved surface inside. An intermediate rejection air knife 10 is provided between the tilting curved surface 9 and the upper conveyor 4. A defect rejection chute 8 is provided below the tilting curved surface 9 and the intermediate rejection air knife 10. The lower conveyor... The lower conveyor 7 has a tail removal air knife 11 at the end away from the upper conveyor 4. Specifically, the free end of the lower conveyor 7 has a transition plate. Several front and back vision inspection lenses 12 are spaced apart above the upper conveyor 4 and the lower conveyor 7. The upper conveyor 4 has a feed chute and a front and back vision recognition lens 5 at the end away from the lower conveyor 7. The front and back vision recognition lens 5 and the front and back vision inspection lens 12 are electrically connected to a control panel 1. Specifically, the front and back vision recognition lens 5 and the front and back vision inspection lens 12 feed back the visual results to the control panel 1.

[0022] In this embodiment, small packages of snack foods enter the upper conveyor 4 through the feeding chute. The front and back visual recognition lens 5 identifies whether the small packages of snack foods are front or back, and then the front and back visual inspection lens 12 on the upper conveyor 4 is used for inspection.

[0023] If it is the front side, check if the inkjet printing is normal. If it is normal, it will enter the flipping surface 9 for flipping. If it is not normal, it will be removed by the middle rejection air knife 10 and discharged through the defect rejection chute 8.

[0024] If it is the reverse side, check whether the impurities in the material exceed the standard. If it is normal, it will enter the flipping surface 9 for flipping; if it is not normal, it will be removed by the intermediate rejection air knife 10 and discharged through the defect rejection chute 8.

[0025] Small packages of snacks entering the flipping curved surface 9 are flipped by the spiral intermediate curved surface and then enter the lower conveyor 7. They are then inspected by the front and back visual inspection lenses 12 on the lower conveyor 7. Depending on whether it is the front or the back, the corresponding inkjet code or impurity standard is detected (as above). If the detection result of the front and back visual inspection lenses 12 is abnormal, it is rejected by the tail rejection air knife 11. If the detection is normal, it enters the next process through the transition plate.

[0026] Furthermore, the upper conveyor 4 is higher than the lower conveyor 7, and both the upper conveyor 4 and the lower conveyor 7 are driven by motors.

[0027] In this embodiment, the upper conveyor 4 is higher than the lower conveyor 7, which facilitates the falling of small packaged snacks from the upper conveyor 4 into the lower conveyor 7 via the flipping curved surface 9; both the upper conveyor 4 and the lower conveyor 7 are driven by motors to transmit power through the conveyor belt.

[0028] Furthermore, both the upper conveyor 4 and the lower conveyor 7 are fitted with supports, and the supports are fitted with external protective covers 2.

[0029] In this embodiment, the front and back visual recognition lens 5, the front and back visual inspection lens 12, and the intermediate removal air knife 10 are all fixed to the bracket and an external protective cover 2 is provided to facilitate the installation of a light source on the external protective cover 2, thereby ensuring that the visual observation of the front and back visual recognition lens 5 and the front and back visual inspection lens 12 is more obvious.

[0030] Furthermore, the control panel 1 is located on the top surface of the outer cover 2.

[0031] In this embodiment, the control panel 1 is located on the top surface of the outer cover 2 for easy observation and operation.

[0032] Furthermore, rack 3 is arranged in a cabinet shape.

[0033] In this embodiment, the rack 3 is arranged in a cabinet shape for convenient storage.

[0034] Furthermore, a visual light source device 6 is provided directly below the front and back visual recognition lens 5.

[0035] In this embodiment, a visual light source device 6 is provided to supplement the light source, thereby ensuring the accuracy of the recognition results.

[0036] The working principle and usage process of this invention: After the invention is installed, it is operated according to the above implementation method until all working steps are completed.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.
