Abstract
Description
Technical Field
[0001] The utility model relates to the field of paper detection, specifically to automatic layering and stacking for black dot detection. Background Technique
[0002] In modern industrial production, the quality control of paper is crucial. Especially in the paper-making industry, the perfection of each piece of paper directly affects the final quality of the product and the market acceptance. Defective paper detection is the first line of defense to ensure product quality. If effective detection is not carried out, some minor problems on the product cannot be discovered in time, which may ultimately lead to large-area defects, affecting the printing effect, and even may result in the abandonment of the finished product, causing economic losses. Therefore, advanced detection equipment and technologies are adopted to strictly screen each batch of paper to ensure that the quality of the output products is stable and meets the standards.
[0003] Black dots are one of the common defects in paper. The black dots may be caused by raw material impurities, pollution during the manufacturing process, or equipment failures, etc. If not properly handled, these detected black dot papers may be mixed into normal papers, increasing the work difficulty and risk of the subsequent processes. Content of the Utility Model
[0004] The purpose of the utility model is to provide automatic layering and stacking for black dot detection to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the automatic layering and stacking for black dot detection includes a fixed frame. A vision camera is arranged on the fixed frame near the paper inlet direction. A stacking mobile cart is arranged on one side of the fixed frame. A pneumatic automatic flap is arranged on the top of the fixed frame. Lower conveying rollers and upper conveying rollers are arranged on the side of the pneumatic automatic flap close to the stacking mobile cart. Blowing mechanisms are arranged on the sides of the lower conveying rollers and the upper conveying rollers close to the pneumatic automatic flap.
[0006] Furthermore: An automatic lifting mechanism is arranged at the bottom of the fixed frame, and a limit switch is arranged on the surface of the automatic lifting mechanism.
[0007] Furthermore: Each of the lower conveying rollers and the upper conveying rollers includes a power roller and a non-power roller. A conveying belt is arranged between the power roller and the non-power roller. One end of the axis of the power roller is fixedly connected to the output end of a motor, and the motor is fixedly installed on the fixed frame.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. In this utility model, advanced detection equipment and technologies are adopted to strictly screen each batch of paper. Defective paper can be automatically separated from good paper for stacking, and paper with black spots can be promptly detected and removed, ensuring the stable quality of the output products and meeting the standards.
[0010] 2. Compared with traditional methods for detecting black spots on paper, it can effectively save time and human resources. The equipment can operate automatically. The conveyance of defective paper can automatically adjust its lifting according to the stacking height, and papers of different qualities can be separated. This can not only prevent good paper from being contaminated but also facilitate subsequent classification processing, such as recycling or selling as secondary products. In addition, reasonable stacking can improve the utilization rate of warehouse space and reduce storage costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this utility model without creative efforts shall fall within the protection scope of this utility model.
[0016] Please refer to Figures 1-3 , the figure shows a preferred embodiment of this utility model, the automatic layered stacking for black spot detection, which includes a fixed frame 1. A vision camera is arranged on the fixed frame 1 near the paper inlet direction. A stacking mobile cart 7 is arranged on one side of the fixed frame 1. A pneumatic automatic flap 2 is arranged on the top of the fixed frame 1. A lower conveying roller 3 and an upper conveying roller 5 are arranged on the side of the pneumatic automatic flap 2 close to the stacking mobile cart 7. Blowing mechanisms 6 are arranged on the sides of the lower conveying roller 3 and the upper conveying roller 5 close to the pneumatic automatic flap 2.
[0017] Specifically, an automatic lifting mechanism 4 is provided at the bottom of the fixed rack 1, and a limit switch 8 is provided on the surface of the automatic lifting mechanism 4.
[0018] Among them, both the lower conveying roller 3 and the upper conveying roller 5 include a driving roller and a non-driving roller. A conveying belt is arranged between the driving roller and the non-driving roller. The axis of one end of the driving roller is fixedly connected to the output end of the motor, and the motor is fixedly installed on the fixed rack 1; after being driven by the motor, the driving roller drives the conveying belt to move, and the paper on its upper part is conveyed to the stacking mobile vehicle 7 through the conveying belt.
[0019] In this embodiment, the black dot detection and layered stacking operation is as follows: The defective part of the paper is detected by the vision camera on one side of the device. When the paper is conveyed to the device, the pneumatic automatic flap 2 is automatically opened. When the paper is normal, the pneumatic flap 2 does not need to move. The genuine paper is conveyed from the upper conveying roller 5 to the stacking mobile vehicle and finally cut according to the conventional size or the required size. When the paper is defective, the pneumatic automatic flap 2 deflects, guiding the defective paper to automatically run from the lower conveying roller 3 to the mobile vehicle for stacking. The defective paper can be utilized in the finished products with low requirements. After the defective paper is cut, the pneumatic automatic flap 2 will automatically close, allowing the genuine paper to be conveyed and stacked from the upper layer, running automatically without manual operation;
[0020] It should be added that a guide rail is provided at the bottom of the stacking mobile vehicle 7, and the stacking mobile vehicle 7 can move horizontally on the guide rail, so that the stacked paper can be spread at different positions; the automatic lifting mechanism 4 can be a cylinder, a hydraulic cylinder or an electric push rod, which controls the angle of the lower conveying roller 3. The lifting of the defective paper conveyor can be automatically adjusted according to the stacking height, and different quality papers can be separated; the blowing mechanism includes a pump machine and an air outlet pipe connected to each other. The air outlet end of the air outlet pipe faces the stacking mobile vehicle 7, and can clean the impurities adhered to the surface of the paper during stacking.
[0021] Finally, it should be noted that in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
