Description

Technical Field

[0001] This utility model relates to the field of paperboard production, and in particular to a device for rejecting defective honeycomb paperboard. Background Technology

[0002] In the paperboard production industry, paperboard undergoes multiple production steps such as bonding, drying, and trimming. These steps easily lead to contamination or damage to the surfaces of the paperboard. Subsequent manual visual inspection is required to remove damaged or contaminated paperboard. However, manual visual inspection is inefficient and prone to missing defects. Therefore, an automated line inspection device has been developed to identify contamination or damage on the paperboard surface. This device is suitable for line paperboard inspection. When damage or contamination is detected, a pushing mechanism pushes the paperboard off the conveyor belt, thus removing defective products. However, the removed paperboard is piled up haphazardly on the ground, requiring manual cleaning and stacking later. Therefore, further improvements are needed. Utility Model Content

The motor is mounted on the end of the frame near the drive wheel and is used to drive the drive wheel.

[0010] The beneficial effects of this invention are: the rejection device can identify defective cardboard and transfer it from the conveyor belt to the stacking table by a robotic arm, so as to facilitate the subsequent recycling of defective cardboard and eliminate the need for manual cardboard handling later. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the rejection device according to an embodiment of the present invention. Detailed Implementation

[0012] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0013] Please refer to the appendix. Figure 1 This utility model provides a defective honeycomb cardboard rejection device, which includes a conveyor belt 1, a robotic arm 2, a paper stacking station 3, and a vision inspection module 4. The vision inspection module 4 and the robotic arm 2 are arranged sequentially along the conveying direction of the conveyor belt 1. The vision inspection module 4 includes a light shield 41, a high frame rate industrial camera 42, and a supplementary light 43. The high frame rate industrial camera detects the cardboard conveyed on the conveyor belt, while the supplementary light provides illumination to the inside of the light shield. The light shield 41 is arranged across the conveying surface of the conveyor belt 1. The high frame rate industrial camera 42 is located at the top inner part of the light shield 41, and the supplementary light 43 is located inside the light shield 41. The robotic arm 2 is located on one side of the conveyor belt 1, and the paper stacking station 3 is located on one side of the robotic arm 2. The robotic arm 2 can transfer the cardboard on the conveyor belt 1 to the paper stacking station 3. The robotic arm uses the detection signal from the high frame rate industrial camera to pick up defective cardboard and put it on the paper stacking station for subsequent recycling of defective products.

[0014] The paper stacking base 3 includes a base plate 31 and multiple retaining posts 32. The base is provided with a cardboard storage area 33.
