Description

Technical Field

[0001] This utility model relates to the field of automatic sorting and collection devices, specifically to a product error prevention screening and collection device. Background Technology

[0002] The screening and collection of goods is a crucial step throughout the entire production flow. Its core requirements lie in accurately separating defective products and efficiently counting and grouping qualified products to ensure the stability of subsequent processes and the quality of delivered goods. "Mistake-proofing" design, as an important means of improving process reliability, can reduce human error through structural or functional design, lowering the risk of defective products flowing into the next stage. However, in current scenarios involving small to medium batches of goods, most screening and collection processes still rely on manual intervention or simple equipment combinations, making it difficult to balance screening accuracy, processing efficiency, and automation. This results in high production flow costs and loopholes in quality control.

[0003] To address the core needs of product screening and collection, various solutions have been developed in related technological fields. For weight-based screening, traditional methods often employ a "manual weighing + manual sorting" model. Operators pick up items one by one beside the conveyor belt, use portable weighing equipment to determine if the weight is acceptable, then separate non-acceptable items, while acceptable items are grouped and stacked according to preset quantities. To improve efficiency, some scenarios have introduced basic automation equipment, typically consisting of a single conveyor belt and a fixed weighing module. The weighing module issues an audible and visual alarm when it detects non-acceptable items, which are then manually removed. In the acceptable item collection stage, fixed bins are often placed at the end of the conveyor belt, and the quantity of items in the bins is manually counted periodically. Once a set value is reached, the bin is replaced to complete the grouping.

[0004] Existing technologies suffer from several shortcomings that urgently need to be addressed, specifically in the following aspects: poor automation and coordination; fragmented screening and collection processes; and a lack of linkage between functions such as weighing, sorting, counting, and grouping. For example, the weighing module and sorting device lack signal interaction, requiring manual intervention to remove defective products. Even after counting qualified products, manual switching of collection paths is still necessary, resulting in low overall process efficiency. Therefore, an integrated and interconnected error-proof screening and collection device is urgently needed to solve these problems. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a product error prevention screening and collection device. Through the segmented design of the conveyor belt system, the coordinated linkage of the guiding device, the weighing device, the air blowing device and the flipping collection device, the automatic guidance of the products, weight detection, rejection of defective products and counting and grouping of qualified products are realized, thereby improving the screening accuracy and collection efficiency and reducing human error.

[0006] Technical Solution: This utility model provides a goods error prevention screening and collection device, comprising: a conveyor belt system, the conveyor belt system including a first conveyor belt, a second conveyor belt and a third conveyor belt connected sequentially along the goods conveying direction; a guiding device, disposed on the first conveyor belt, for guiding goods to be conveyed along a preset trajectory; a weighing device, disposed on the second conveyor belt, for detecting the weight of the goods; an air blowing device, installed on the side of the third conveyor belt and signal-connected to the weighing device, for blowing away goods from the conveyor belt when the weighing device detects goods with unqualified weight; a collection channel, disposed on the other side of the third conveyor belt opposite to the air blowing device, its position corresponding to the air blowing device, for receiving the blown-away unqualified goods and guiding them to fall into a collection box on the ground; and a flipping collection device, disposed at the end of the third conveyor belt, for counting and grouping qualified goods for collection. By sequentially connecting the first, second, and third conveyor belts, the entire process of goods being transported continuously from entering the device to completion of screening and classification is achieved. This ensures the continuity of the production process, avoids goods accumulation or transport interruptions, and establishes a signal linkage between the weighing device and the air blowing equipment. When the weight of the goods exceeds the acceptable range, a control signal can be sent to the air blowing equipment in real time to trigger the air blowing action, realizing the automated identification and sorting of non-conforming products without the need for manual intervention. The flipping collection device at the end of the third conveyor belt can count the qualified goods that have passed the screening in real time, replacing manual counting operations and reducing counting errors. According to preset parameters, the flipping collection device can complete the flipping action when the count reaches the set value, collecting the qualified goods in fixed groups to meet the standardized requirements of subsequent packaging and warehousing.

[0007] Furthermore, this application discloses a product error-proof screening and collection device, wherein the flipping collection device includes: a frame; a pair of inclined guide plates symmetrically inclined on the frame; a pair of infrared counters respectively disposed on the sides of the two inclined guide plates for counting products sliding down them; a flipping guide plate rotatably disposed on the upper end of the frame via a rotating shaft; and a pair of cylinders mounted on the frame, the driving ends of which are respectively connected to the lower side of the flipping guide plate for driving the flipping guide plate to flip around the rotating shaft, so that it can selectively overlap with one of the inclined guide plates on one side; wherein, after qualified products fall onto the flipping guide plate, they slide down its inclined surface to the currently overlapped inclined guide plate and are counted by the infrared counter on that side; when the count reaches a set value, the cylinder on that side drives the flipping guide plate to flip, so that it overlaps with the inclined guide plate on the other side, thereby switching the product collection path. By selectively overlapping the flip guide plate and the inclined guide plate, the goods are guided to slide down along the set path to avoid deviation.

[0008] Furthermore, in this application, a goods error-proof screening and collection device includes an air blowing device comprising: a fixed plate; a pair of adjustable upright plates vertically fixed to the fixed plate, each adjustable upright plate having an elongated slot; and a pair of air blowing components mounted on the fixed plate, each air blowing component including an air nozzle. The fixed plate is vertically adjustable via bolts passing through the elongated slots. By cooperating with the bolts in the elongated slots on the adjustable upright plates, the vertical position of the fixed plate (and the air blowing components mounted thereon) can be adjusted, allowing for flexible adjustment of the air nozzle height according to the goods height.

[0009] Furthermore, in one product error-proof sorting and collection device of this application, the storage channel is generally box-shaped, with an opening on its side wall directly opposite the air blowing component. Products blown away enter the storage channel through this opening and fall down. The box-shaped structure forms a closed storage space, guiding the entering products to fall vertically along the channel and preventing them from scattering.

[0010] Furthermore, in this application, a goods error-proof screening and collection device includes a guiding device comprising a pair of baffles respectively disposed on both sides of the first conveyor belt. Each baffle is fitted with a set of adjustable rods that can be adjusted perpendicular to the conveying direction, and the ends of the adjustable rods are provided with baffles. Each baffle includes a connected limiting part and a guiding part. The limiting parts on both sides are parallel to each other, forming a limiting channel for goods to pass through. The guiding parts on both sides are arranged in a figure-eight shape, with their open ends facing the direction of goods coming from. By adjusting the baffles with the adjustable rods that can be adjusted perpendicular to the conveying direction, the limiting parts of the baffles can be moved synchronously, realizing flexible adjustment of the width of the limiting channel to accommodate goods of different sizes (widths). The guiding parts of the baffles on both sides are arranged in a figure-eight shape, with their open ends facing the direction of goods coming from, which can guide and correct goods that deviate during the conveying process, allowing them to automatically slide into the middle limiting channel.

[0011] Furthermore, in one of the goods error-proof screening and collection devices of this application, a cover is provided on the second section of the conveyor belt. The cover serves to protect against dust.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The product error prevention screening and collection device described in this utility model achieves automatic product guidance, weight detection, rejection of defective products, and counting and grouping of qualified products through the segmented design of the conveyor belt system, the coordinated linkage of the guiding device, the weighing device, the air blowing device and the flipping collection device. This improves the screening accuracy and collection efficiency, reduces human error, and solves the problem of poor automation coordination in the prior art.

[0013] 2. The goods error prevention screening and collection device of this utility model can adapt to goods of different sizes and heights through an adjustable guiding device and an air blowing device, which enhances the versatility and flexibility of the device. At the same time, the flipping collection device realizes accurate counting and automatic grouping of qualified goods through infrared counting and cylinder-driven flipping, which further improves the reliability and efficiency of the collection process.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 like Figure 1-4 As shown, this embodiment provides a product error prevention screening and collection device for the automated screening and collection of seasoning packets. The device includes a conveyor belt system 1, which comprises a first conveyor belt 11, a second conveyor belt 12, and a third conveyor belt 13 connected sequentially along the product conveying direction.

[0018] The first conveyor belt 11 is equipped with a guiding device 2 to guide the seasoning packets along a preset trajectory. The guiding device 2 includes a pair of baffles 21 respectively disposed on both sides of the first conveyor belt 11. Each baffle 21 is fitted with a set of adjustable rods 22 that can be adjusted perpendicular to the conveying direction. The ends of the adjustable rods 22 are provided with baffles 23. The baffles 23 include connected limiting parts 231 and guiding parts 232. The limiting parts 231 on both sides are parallel to each other, forming a limiting channel for the goods to pass through. The guiding parts 232 on both sides are arranged in a figure-eight shape, with their open ends facing the direction of the goods. By adjusting the adjusting rods 22, the width of the limiting channel can be flexibly adjusted to accommodate seasoning packets of different sizes.

[0019] The second conveyor belt 12 is equipped with a cover 6 to protect the weighing device from dust from the seasoning packets. The weighing device, located on the second conveyor belt 12, is used to detect the weight of the seasoning packets. When a seasoning packet passes through the weighing device, the system automatically determines whether its weight is within the acceptable range.

[0020] A blowing device 3 is installed on the side of the third conveyor belt 13 and is connected to the weighing device. It is used to blow a seasoning packet away from the conveyor belt when the weighing device detects a substandard weight. The blowing device 3 includes a fixed plate 31, a pair of adjustable upright plates 32, and a pair of blowing components 33. The adjustable upright plates 32 are vertically fixed to the fixed plate 31, and each adjustable upright plate 32 has an elongated slot 321. The blowing components 33 are installed on the fixed plate 31, and each blowing component 33 includes a blowing nozzle 331. The fixed plate 31 is adjusted vertically by bolts passing through the elongated slots 321, allowing the height of the blowing nozzles 331 to be flexibly adjusted according to the height of the seasoning packet.

[0021] The third conveyor belt 13 has a storage channel 4 on the other side of the blowing device 3. The storage channel 4 is in the shape of a square box. An opening 41 is provided on its side wall facing the blowing component 33. The unqualified seasoning packets that are blown away enter the storage channel 4 through this opening 41 and fall into the storage box on the ground.

[0022] At the end of the third conveyor belt 13, a flipping and collecting device 5 is provided for counting and grouping qualified seasoning packets. The flipping and collecting device 5 includes a frame 51, a pair of inclined guide plates 52, a pair of infrared counters 55, a flipping guide plate 53, and a pair of cylinders 54. The inclined guide plates 52 are symmetrically inclined on the frame 51, and the infrared counters 55 are respectively set on the sides of the two inclined guide plates 52 to count the seasoning packets sliding down them. The flipping guide plate 53 is rotatably mounted on the upper end of the frame 51 via a rotating shaft. The cylinders 54 are mounted on the frame 51, and their driving ends are respectively connected to the lower side of the flipping guide plate 53 to drive the flipping guide plate 53 to flip around the rotating shaft, so that it can selectively overlap with one of the inclined guide plates 52.

[0023] The specific working process is as follows: The seasoning packets enter from the first conveyor belt 11, are guided into the limiting channel by the guide device 2, and are automatically slid into the limiting channel by the guide part 232 of the adjusting rod 22 and the baffle 23. The seasoning packets are conveyed from the first conveyor belt 11 to the second conveyor belt 12, where the weight is detected by the weighing device. Seasoning packets that do not meet the weight requirements are blown off the conveyor belt by the air blowing device 3's air nozzle 331 triggered by the weighing device signal, and fall into the storage box through the opening 41 of the storage channel 4. Seasoning packets that meet the weight requirements continue to be conveyed to the third conveyor belt 13, reach the flipping collection device 5, slide down the flipping guide plate 53 to the currently overlapping inclined guide plate 52, and are counted by the infrared counter 55 on that side. When the count reaches a set value (e.g., 50 packets), the cylinder 54 on this side drives the flipping guide plate 53 to flip, so that it overlaps with the inclined guide plate 52 on the other side, thereby switching the collection path of the seasoning packets and realizing the automatic grouping and collection of qualified seasoning packets.

[0024] In this embodiment, through the segmented design of the conveyor belt system and the coordinated operation of the guiding device, weighing device, air blowing device and flipping collection device, the automatic guidance, weight detection, rejection of defective products and counting and grouping of qualified products of seasoning packets are realized, which significantly improves the screening accuracy and collection efficiency, reduces human error, and is particularly suitable for the automated screening and collection of small and medium batches of goods such as seasoning packets.

[0025] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
