Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehousing and logistics, and in particular to a sorting and placement device for warehousing and logistics goods. Background Technology
[0002] In warehousing and logistics, there are various types of equipment used for classifying and placing goods. Shelving is the most basic classification and placement equipment in warehousing and logistics. In the storage management of small and medium-sized warehouses, medium-duty shelving is widely used for the storage of daily necessities, light industrial products or parts due to its significant advantages such as simple structure, moderate height and ease of manual handling.
[0003] When using medium-duty shelving for storage, a common practice is to directly stack goods on the shelves. Following the first-in, first-out (FIFO) principle, goods at the bottom should be removed first. However, due to the stacking, removing items from the bottom can easily cause similar items to tip over, damaging the goods, disrupting the neatness of the stack, increasing subsequent handling workload and difficulty, and reducing overall warehouse efficiency. To ensure neat stacking, existing technologies use storage boxes to hold goods before placing them on the shelves. This method partially solves the problem of goods tipping over when directly stacked, ensuring neatness on the shelves. However, because the volume of goods shipped is uncertain, it's difficult to guarantee that all goods in each storage box can be shipped out each time. Therefore, goods at the bottom of the storage boxes are not prioritized for shipment and remain there, easily disrupting the storage order and increasing the difficulty of inventory counting and management.
[0004] Therefore, this utility model provides a sorting and placement device for warehousing and logistics goods to meet the needs. Utility Model Content
[0005] The technical problem this utility model aims to solve is to provide a classification and placement device for warehousing and logistics goods. By setting limiting components, it can not only maintain the neatness of the goods placement but also provide stable protection for the goods, improving the stability of goods storage. At the same time, it can orderly remove goods from the bottom of the stack while following the first-in-first-out (FIFO) principle, avoiding the pulling and tipping of goods. This reduces the extra sorting work caused by the tipping of goods and avoids the problem of goods remaining at the bottom. It ensures the clarity and stability of the goods storage order, reduces the difficulty of inventory counting and management, and improves the accuracy and efficiency of warehouse management. Through the above settings, it can solve the problems of goods damage and uneven stacking caused by direct stacking of goods, as well as the problems of goods being difficult to follow the FIFO principle for stable delivery, which leads to the accumulation of goods and disrupts the storage order and increases the difficulty of inventory counting and management.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sorting and placement device for warehousing and logistics goods includes two symmetrically arranged uprights, with multiple crossbeams equidistantly spaced between the two uprights, each crossbeam having a shelf, and each crossbeam having a support shaft on one side; and a limiting component for limiting the goods placed on top of the shelf, the limiting component being connected to the shelf and the support shaft respectively.
[0007] Optionally, the limiting component includes a limiting frame that rotates on the surface of the support shaft. One side of the limiting frame is in contact with the bottom of the shelf near the support shaft, and the other side of the limiting frame has a gap with the shelf away from the support shaft.
[0008] Optionally, the limiting frame includes a rotating part that rotates on the surface of the support shaft. A limiting part and a connecting part are respectively connected to both sides of the rotating part. The cross-section of the limiting part is an inverted U-shape with an opening facing downwards. The limiting part and the connecting part are arranged perpendicularly. There is a gap between one side of the limiting part and the shelf away from the support shaft. The connecting part is in contact with the bottom of the shelf near the support shaft.
[0009] Optionally, the end of the limiting part away from the rotating part is connected to an abutting part one, which abuts against one side of the cargo.
[0010] Optionally, a roller is provided between the limiting part and the abutting part, and a partition curtain is wound on the roller.
[0011] Optionally, the limiting part is provided with symmetrical sliding grooves on one side, and sliding columns are slidably provided in both sliding grooves. One end of each sliding column passes through the sliding groove and is fixed to the bottom two sides of the barrier curtain respectively.
[0012] Optionally, a limiting button is provided at the bottom of the inner wall of the groove, and the limiting button abuts against the surface of the sliding column.
[0013] Optionally, an elastic part is connected to the end of the connecting part away from the rotating part, and an abutting part two is connected to the end of the elastic part away from the connecting part, the abutting part two abutting against the top of the goods.
[0014] Optionally, a counterweight is provided on one side of the connecting part, and one side of the counterweight is in contact with the bottom of the shelf.
[0015] Optionally, a lightweight groove is formed on the surface of the connecting part.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting up limiting components, not only can the neatness of the goods be maintained and the space utilization of the warehouse be improved, but the goods can also be stably protected, preventing stacked goods from being accidentally knocked over, thus improving the stability of goods storage and reducing the risk of goods damage. At the same time, when goods are being orderly removed from the bottom of the stack according to the first-in-first-out principle, it is possible to prevent goods from being pulled out and tipped over, reducing the extra sorting work caused by goods tipping over, thereby improving the overall operational efficiency of the warehouse. It also avoids the problem of goods remaining at the bottom, ensuring the clarity and stability of the goods storage order, reducing the difficulty of inventory counting and management, and improving the accuracy and efficiency of warehouse management.
[0017] By setting up limit racks, not only can the neatness of the goods be maintained, but they also provide stable protection for the goods, preventing stacked goods from being accidentally knocked over, improving the stability of goods storage, reducing the risk of goods damage, avoiding the problem of goods remaining at the bottom, ensuring the clarity and stability of goods storage order, reducing the difficulty of inventory counting and management, and improving the accuracy and efficiency of warehouse management.
[0018] By setting up abutment part one and abutment part two, the top and sides of the goods can be limited respectively. While maintaining the neatness of the goods, it also plays a stable protective role for the goods, which can prevent stacked goods from being accidentally bumped and tipped over, thus improving the stability of goods storage.
[0019] By installing partition curtains, and with the cooperation of the partition curtains and the abutment part, the goods placed there can be further protected, ensuring the stability of the goods storage. Attached Figure Description

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0025] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0026] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.
[0027] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.
[0028] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.
[0029] like Figures 1 to 7 As shown, an embodiment of this utility model provides a sorting and placement device for warehousing and logistics goods, including two symmetrically arranged uprights 1, with multiple crossbeams 2 equidistantly spaced between the two uprights 1. Each crossbeam 2 has a shelf 3. By setting multiple crossbeams 2 between the two uprights 1 and placing a suitable number of shelves 3 on top of each crossbeam 2, a support shaft 4 is provided on one side of each crossbeam 2. The support shaft 4 is installed together with the crossbeam 2. The splicing part of the medium-duty shelving is disclosed as prior art and will not be described in detail here. A limiting component is used to limit the goods placed on top of the shelves 3. The limiting component is connected to both the shelf 3 and the support shaft 4. When the worker sorts and places the goods on the corresponding shelf 3, the limiting component rotates synchronously along the axis of the support shaft 4, thus limiting the top of the placed goods. The limit switch can also restrict the movement of goods on the sides, which not only maintains the neatness of the goods and improves the space utilization of the warehouse, but also provides stable protection for the goods, preventing stacked goods from being accidentally knocked over, improving the stability of goods storage, reducing the risk of goods damage, and preventing goods from being pulled out and tipped over when orderly unloading from the bottom of the stack according to the first-in-first-out principle. This allows staff to carry out unloading operations more smoothly, improves unloading efficiency, reduces the extra work caused by goods tipping over, and thus improves the overall operational efficiency of the warehouse. Adhering to the first-in-first-out principle also avoids the problem of goods remaining at the bottom, ensuring the clarity and stability of the goods storage order, reducing the difficulty of inventory counting and management, and improving the accuracy and efficiency of warehouse management.
[0030] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, the limiting assembly includes a limiting frame 5, which rotates on the surface of the support shaft 4. It is understood that the support shaft 4 is installed only after the limiting frame 5 is installed on it. One side of the limiting frame 5 is in contact with the bottom of the shelf 3 near the support shaft 4, while the other side of the limiting frame 5 has a gap with the shelf 3 away from the support shaft 4. It is understood that the gap between the limiting frame 5 and the shelf 3 is sufficient to allow for the smooth removal of at least one item. Furthermore, both sides of the limiting frame 5 are in contact with the bottom of the shelf 3 above the item and have gaps with the top of the shelf 3 where the item is currently placed. When workers sort and place items, one side of the limiting frame 5 moves along the support shaft 4 as the item is placed. The axis of shaft 4 rotates closer to the bottom of the shelf 3 above the goods until it is in contact with the goods. At this time, the limiting frame 5 simultaneously limits the top and sides of the goods. This not only maintains the neatness of the goods and improves the space utilization of the warehouse, but also provides a stable protection for the goods. It can prevent the stacked goods from being accidentally knocked over, improve the stability of goods storage, and reduce the risk of goods damage. There is a gap between the other side of the limiting frame 5 and the top of the shelf 3 where the goods are currently placed, which makes it easy to pull the goods from the bottom of the stacked goods to complete the first-in-first-out of the goods. This avoids the problem of the bottom goods being stuck, ensures the clarity and stability of the goods storage order, reduces the difficulty of inventory counting and management, and improves the accuracy and efficiency of warehouse management.
[0031] It should be noted that the appendix Figure 1 and attached Figure 2 The image only shows the limiting status of one of the five limiting racks on one floor. This is for illustrative purposes only. The actual number of racks used can be increased or decreased depending on the specific situation. No specific limits or further details are provided here.
[0032] In this embodiment, as Figures 1 to 4As shown, the limiting frame 5 includes a rotating part 6, which rotates on the surface of the support shaft 4. A limiting part 7 and a connecting part 14 are respectively connected to both sides of the rotating part 6. The limiting part 7 has a U-shaped cross-section with an opening facing downwards. The limiting part 7 and the connecting part 14 are vertically arranged. There is a gap between one side of the limiting part 7 and the shelf 3 away from the support shaft 4. The connecting part 14 is in contact with the bottom of the shelf 3 near the support shaft 4. When workers place goods, one side of the goods pushes one side of the connecting part 14 towards the width direction of the shelf 3. Under the action of the rotating part 6, the limiting part 7 and the connecting part 14 rotate synchronously along the surface of the support shaft 4. After the goods are placed, as described above, one side of the connecting part 14 is in contact with the bottom of the shelf 3 above the goods. The connecting part 14 fits snugly, and the other side of the connecting part 14 abuts against the top of the goods, limiting the top of the goods. The limiting part 7 is set perpendicular to the connecting part 14. At this time, the limiting part 7 abuts against the side of the goods, limiting the side of the goods. While maintaining the neatness of the goods, it also plays a stable protective role for the goods, which can prevent the stacked goods from being accidentally bumped and tipped over, thus improving the stability of goods storage. There is a gap between the limiting part 7 and the top of the shelf 3 where the goods are currently placed, so that the goods can follow the first-in-first-out rule to achieve stable delivery. The cross-section of the limiting part 7 is an inverted U-shape with an opening facing downwards, which provides space for the staff to place the goods when the limiting part 7 rotates with the connecting part 14, without interfering with the placement of the goods.
[0033] In this embodiment, as Figures 3 to 7 As shown, the end of the limiting part 7 away from the rotating part 6 is connected to the abutting part 8. The abutting part 8 abuts against one side of the goods. After the goods are placed, the inner side of the abutting part 8 abuts against the side of the goods, limiting the side of the goods and preventing the goods from tipping over and falling, which helps to ensure the stability of the goods storage.
[0034] In this embodiment, as Figure 3 , Figure 6 and Figure 7 As shown, a roller 9 is provided between the limiting part 7 and the abutting part 8. A partition curtain 10 is wound on the roller 9. It can be understood that a coil spring is provided on the roller 9, and the two ends of the coil spring are fixed to one side of the roller 9 and the partition curtain 10, respectively. This enables the automatic winding of the partition curtain 10. The partition curtain 10 can cover the downward-facing chamfered side of the limiting part 7, thereby providing further protection for the placed goods and ensuring the stability of the goods storage.
[0035] In this embodiment, as Figure 3 and Figure 4As shown, the limiting part 7 has symmetrically provided sliding grooves 11 on one side, and sliding columns 12 are slidably provided in both sliding grooves 11. One end of each sliding column 12 passes through the sliding groove 11 and is fixed to the bottom two sides of the partition curtain 10 respectively. It can be understood that when the partition curtain 10 is unfolded, it can provide further protection for the placed goods. When the partition curtain 10 is rolled up, it can provide sufficient space for the staff to place goods. During the opening and closing of the partition curtain 10, the sliding columns 12 slide in the sliding grooves 11, which effectively guides the opening and closing of the partition curtain 10, so that the partition curtain 10 can be opened and closed smoothly.
[0036] In this embodiment, as Figures 3 to 5 As shown, a limiting button 13 is provided at the bottom of the inner wall of the slide groove 11. The limiting button 13 abuts against the surface of the sliding column 12. As mentioned above, when the sliding column 12 and the barrier curtain 10 slide to the bottom of the inner wall of the slide groove 11, the limiting button 13 limits the sliding column 12, thereby ensuring the stability of the barrier curtain 10 in protecting the goods. When the barrier curtain 10 needs to be rolled up, the operator can manually lift the bottom of the barrier curtain 10 upward to overcome the frictional force of the limiting button 13 limiting the sliding column 12. It can be understood that the frictional force of the limiting button 13 limiting the sliding column 12 is greater than the elastic force of the barrier curtain 10 automatically rolling up. This part is disclosed as prior art and will not be elaborated on here.
[0037] In this embodiment, as Figures 3 to 7 As shown, the end of the connecting part 14 away from the rotating part 6 is connected to an elastic part 15, and the end of the elastic part 15 away from the connecting part 14 is connected to an abutting part 2 16. The abutting part 2 16 abuts against the top of the goods. When the connecting part 14 is in contact with the bottom of the shelf 3 located above the goods, under the cooperation of the elastic part 15 and the abutting part 2 16, the elasticity of the elastic part 15 makes the abutting part 2 16 always in contact with the top of the goods, which can not only ensure the limit of the top of the goods, but also not affect the shipment of the goods.
[0038] In this embodiment, as Figures 3 to 7 As shown, a counterweight 17 is provided on one side of the connecting part 14. One side of the counterweight 17 is attached to the bottom of the shelf 3. It can be understood that the attachment between the counterweight 17 and the shelf 3 can be a magnetic or snap-fit method as in the prior art. No specific limitation or further description is given here. The counterweight 17 is used to limit the rotation position of the connecting part 14, which helps to maintain the stable limit of the top of the goods by the abutment part 16 and the stable delivery of the goods. When not in use, the counterweight 17 is attached to the bottom of the shelf 3, so that the entire limiting frame 5 can be completely stored between the shelves 3 without occupying the movement space in the warehouse. When in use, the staff pulls one side of the limiting part 7 to separate the counterweight 17 from the bottom of the shelf 3. Under the action of gravity, the connecting part 14 can be driven to be perpendicular to the shelf 3, and the limiting part 7 parallel to the shelf 3, so that it can be switched to a position that is convenient for the placement of goods.
[0039] In this embodiment, as Figure 3 and Figure 4 As shown, the surface of the connecting part 14 is provided with a lightweight groove 18, which, together with the sliding groove 11 on one side of the limiting part 7, effectively reduces the weight of the limiting frame 5. The lightweighting of the limiting frame 5 not only facilitates installation but also saves on the cost of production materials.
[0040] The working principle of the technical solution provided by this utility model is as follows: Before use, staff members assemble the upright frame 1, crossbeam 2, support shaft 4, and limiting frame 5 in sequence according to storage needs, and place the corresponding shelves 3. When not in use, the counterweight 17 is attached to the bottom of the shelf 3, so that the entire limiting frame 5 can be completely stored between the shelves 3 without occupying the movement space in the warehouse. When in use, staff members pull one side of the limiting part 7 to separate the counterweight 17 from the bottom of the shelf 3. Under the action of gravity, the connecting part 14 can be driven to be perpendicular to the shelf 3, and the limiting part 7 can be parallel to the shelf 3, so that it can be switched to a position that is convenient for goods to be placed. At this time, the partition curtain 10 is in a rolled-up state. When staff sort and place goods, one side of the goods pushes one side of the limiting frame 5 connecting part 14 towards the width of the shelf 3. Under the action of the rotating part 6, the limiting part 7 and the connecting part 14 of the limiting frame 5 rotate synchronously along the surface of the support shaft 4 until the counterweight 17 on one side of the connecting part 14 is in contact with the bottom of the shelf 3 above the goods. The second abutment part 16 on the other side of the connecting part 14 abuts against the top of the goods, limiting the top of the goods. At this time, the first abutment part 8 on one side of the limiting part 7 abuts against the side of the goods, limiting the goods. The side of the partition curtain 10 is used to limit the movement of goods and maintain their neatness. After the goods are placed, the staff pulls the bottom of the partition curtain 10 down until the limit button 13 and the sliding block 12 are against each other. This allows the partition curtain 10 to work with the abutment part 8 to effectively protect the goods and ensure the stability of the storage. When it is necessary to ship the goods, the staff can ship them out in an orderly manner through the gap between the bottom of the limit part 7 and the top of the goods placement shelf 3. This ensures that the goods are shipped out first in first out, avoids the retention of goods at the bottom, and improves the accuracy and efficiency of warehouse management.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
