Description

Technical Field

[0001] This application relates to the field of visual inspection technology for PP material products, and in particular to a layout device for visual inspection of PP material products. Background Technology

[0002] Polypropylene (PP) is widely used in various fields and can be used to make a variety of products due to its unique properties, such as high temperature resistance, chemical corrosion resistance, lightweight, and low cost. These include food packaging such as cling film, food bags, beverage bottles, and disposable tableware; non-food packaging such as cosmetic packaging and daily necessities packaging, such as detergent bottles and shampoo bottles; and applications in textile products, the automotive industry, home appliances, and medical devices. Its uses are extremely wide-ranging.

[0003] Currently, due to the large usage of PP material products, mass production is underway, such as beverage bottles and bottle caps. PP products are typically transparent, and defects such as black spots are quite noticeable during production, leading to defective or scrap products. Therefore, quality inspection (including burrs and flash) is necessary during production. Current technology allows for photo-based visual inspection, effectively improving inspection efficiency. However, before inspection, the batch of products needs to be arranged to avoid affecting the inspection results due to stacking. Bottles are larger and generally do not have stacking issues, while bottle caps are smaller and prone to stacking, which can affect photo-based inspection. Currently, vibratory feeding systems for small products like bottle caps can achieve single-layer transport, but stacking still occurs during vibration. Figure 3 The problem shown at point a) means that the detection effect still exists. Summary of the Invention

[0004] To address the aforementioned problems, this application aims to provide a layout device for visual inspection of PP material products, which ensures that products can be photographed and inspected in a single-layer conveying manner, thereby effectively solving the impact of photographing stacked small PP products on the inspection quality and improving the accuracy of product inspection.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A layout device for visual inspection of PP material products includes a vibratory plate, an accumulation groove is provided in the middle of the vibratory plate, a spiral conveyor belt is provided on the outside of the accumulation groove, one end of the spiral conveyor belt is connected to the accumulation groove, and the other end extends to the outside of the vibratory plate, a rejection plate is provided above the outer end of the spiral conveyor belt, the rejection plate is set at an angle to the outer end of the spiral conveyor belt, and the gap between the bottom side of the rejection plate and the surface of the spiral conveyor belt is greater than the thickness of one product and less than the thickness of two products.

[0006] Preferably, one end of the rejection plate is provided with a support plate, and the other end of the support plate is fixed to the outer wall of the vibratory plate by bolts, and an adjustment hole is vertically opened at the bolt insertion point on the support plate.

[0007] Preferably, the rejection plate is configured as an arc-shaped plate structure.

[0008] Preferably, a return trough plate is provided across the outer end of the rejection plate and the spiral conveyor belt, the return trough plate is inclined downward and the bottom end extends into the accumulation tank.

[0009] Preferably, the rejection plate is also provided at the junction of the accumulation tank and the spiral conveyor belt.

[0010] The beneficial effects of this application are: by setting up a rejection plate, this application can remove the stacked products that still exist in the arrangement process of the vibratory feeder from the spiral conveyor belt, ensuring that the products can be photographed and inspected in a single-layer conveying manner, thereby effectively solving the impact of photographing stacked small PP products on the inspection quality and improving the accuracy of product inspection.

[0011] By setting up a return trough plate, rejected stacked products can be returned to the vibratory feeder for arrangement, avoiding contact contamination problems caused by manual collection. At the same time, a rejection plate is set at the inlet on the lower side of the spiral conveyor belt, so that stacked products can be rejected in the initial stage of conveying. This, together with the rejection plate on the upper side, achieves two rejection points, further ensuring that the inspected products are single-layered. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached document Figures 1-9 The diagram shows a visual inspection arrangement device for PP material products, including a vibratory feeder 1. An accumulation groove 1a is located in the center of the vibratory feeder 1, and a spiral conveyor belt 11 is located outside the accumulation groove 1a. One end of the spiral conveyor belt 11 is connected to the accumulation groove 1a, and the other end extends to the outside of the vibratory feeder 1. Currently, this device is used for inspecting products such as bottle caps. Figure 1 When arranging the products (as shown), the batch-produced products are lifted and accumulated into the collection tank 1a of the vibratory plate 1 by the elevator (not shown in the figure). Under the action of vibration and conveying by the spiral conveyor belt 11, the products in the collection tank 1a will be gradually conveyed through the spiral collection tank 1a to realize the individual arrangement of small bottle cap products.

[0024] And such Figure 3-4 As shown, when products enter the spiral conveyor belt 11 from the bottom side, due to the large accumulation of products in the accumulation tank 1a, products may still be stacked and enter the spiral conveyor belt 11. Since the stacked products do not vibrate after entering the spiral conveyor belt 11, they will continue to be conveyed to the photographic inspection area. The stacked products will affect the photographic inspection. Therefore, to solve this problem, such as... Figure 5-7 As shown, this application provides a rejection plate 2 above the outer end of the spiral conveyor belt 11. The rejection plate 2 is set at an angle to the outer end of the spiral conveyor belt 11, and the gap between the bottom side of the rejection plate 2 and the surface of the spiral conveyor belt 11 is greater than the thickness of one product and less than the thickness of two products.

[0025] When the stacked products are conveyed to the rejection plate 2 via the spiral conveyor belt, the height of the stacked products is greater than the gap between the rejection plate 2 and the spiral conveyor belt 11. Therefore, the rejection plate 2 blocks the stacked products. Under the blocking effect, the stacked products come into contact with the rejection plate 2 and fall off the spiral conveyor belt 11 at an angle along the surface of the rejection plate 2 and the spiral conveyor belt 11. This solves the problem of the stacked products continuing to be conveyed to the inspection area for testing. If the products are arranged in a single layer, they can pass smoothly through the gap between the rejection plate 2 and the spiral conveyor belt to be conveyed to the inspection area for testing. Therefore, by setting the rejection plate 2, the impact of stacked products on the quality of photographic inspection can be effectively solved, and the accuracy of product inspection can be improved.

[0026] There are many types of PP products. To achieve the goal of rejecting products of different thicknesses after lamination, such as... Figure 5 As shown, a support plate 3 is provided at one end of the rejection plate 2, and the other end of the support plate 3 is fixed to the outer wall of the vibratory feeder 1 by bolts 4. An adjustment hole (not shown in the figure) is vertically opened at the point where the bolts 4 pass through the support plate 3. The height of the support plate 3 can be adjusted through the adjustment hole, thereby adjusting the height of the rejection plate 2 and the gap between the rejection plate 2 and the spiral conveyor belt 11, so that the gap is between the thickness of a single product and the thickness of two products, thereby realizing the rejection of products of different thicknesses when they are stacked.

[0027] To facilitate the smooth removal of laminated products from the spiral conveyor belt 11 after contact with the rejection plate 2, such as Figure 6 As shown, the rejection plate 2 is configured as an arc-shaped plate structure. Compared with a flat plate structure, the arc-shaped plate structure can avoid jamming of the stacked products after contacting the rejection plate 2, and facilitate the smooth removal of the stacked products from the spiral conveyor belt 11.

[0028] To allow the stacked products to be returned to the vibratory feeder 1 for further arrangement, such as... Figure 8 As shown, a return trough plate 5 is provided across the outer end of the rejection plate 2 and the spiral conveyor belt 11. The return trough plate 5 is inclined downwards, and its bottom end extends into the accumulation tank 1a. After the laminated products come into contact with the rejection plate 2, they fall along the rejection plate 2 onto the return trough plate 5. The inclined arrangement of the return trough plate 5 allows the laminated products to slide down into the accumulation tank 1a under gravity and re-enter the arrangement process, realizing direct return of the laminated products and solving the problems of manually collecting the accumulated laminated products and the surface contamination of the products during the collection process.

[0029] To prevent stacking of products when they enter the spiral conveyor belt 11, such as Figure 9As shown, a rejection plate 2 is also provided at the junction of the accumulation tank 1a and the spiral conveyor belt 11. This rejection plate 2 is used to reject products when they are stacked and enter the spiral conveyor belt 11. Together with the rejection plate 2 at the top of the spiral conveyor belt 11, it achieves a dual rejection function, further ensuring that the product is a single layer during subsequent photographic inspection. The lower rejection plate 2 is also fixed to the side wall of the spiral conveyor belt (with adjustment holes) by bolts 4, allowing for height adjustment.

[0030] The principle of this application is as follows: When arranging small PP products through the vibratory feeder 1, if there are stacked products on the spiral conveyor belt 11, they are first directly rejected by the lower rejection plate 2 into the collection tank 1a. If, under the action of vibration, the products in the collection tank 1a jump over the lower rejection plate 2 and stack on the already conveyed products, when they are conveyed to the upper rejection plate 2, they are rejected from the spiral conveyor belt 11 by the upper rejection plate 2 and fall into the return trough plate 5. The rejected stacked products slide down the return trough plate 5 into the collection tank 1a for re-arrangement.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
