Description
Technical Field
[0001] This utility model belongs to the field of steel sorting technology, and in particular relates to a non-standard length steel sorting device and sorting system. Background Technology
[0002] In steel production and sales, "fixed length" and "non-fixed length" are two common steel length specifications. The main difference between them lies in the degree of standardization of length and application scenarios.
[0003] Custom-length steel refers to steel produced to a fixed length specified by the user. This length is predetermined and is typically used in projects or processing scenarios requiring precise dimensions. Due to the need for customized production, its production cost and selling price are usually higher than non-custom-length steel. Non-custom-length steel refers to steel produced within a standard length range during the production process, with its length usually exhibiting some fluctuation (e.g., 6-12 meters, 9-15 meters, etc.). The length of this type of steel is not fixed but determined based on the actual conditions during the production process.
[0004] On a hot-rolled steel production line, steel is conveyed from the cooling bed to a shearing machine for cutting to length to obtain standard-length steel. During this process, the first and last shears may produce some short-length steel. To ensure the quality of the finished product, these short-length steel pieces must be separated from the standard-length steel pieces before entering the bundling machine.
[0005] Currently, the separation of short-length steel is mainly done manually on the CD roller conveyor. Workers need to quickly identify and pick out the short-length steel on the conveyor rollers using tools such as hooks. However, when there is a large quantity of steel, workers cannot hook the short-length steel off the CD roller conveyor in time, and some short-length steel will still enter the baling machine. Utility Model Content
[0006] The purpose of this invention is to provide a non-standard length steel sorting device and sorting system to promptly screen short-length steel materials on the CD roller conveyor and improve production efficiency.
[0007] The present invention adopts the following technical solution: a non-standard length steel sorting device, comprising columns respectively arranged on both sides of the CD roller conveyor;
[0008] A horizontal fixing rod is installed between the two columns. The fixing rod extends from one side of the CD roller conveyor to the other side, and the fixing rod is higher than the roller body of the CD roller conveyor.
[0009] It also includes a movable rod, which is set parallel to the fixed rod and located directly below the fixed rod;
[0010] The guard plate of the CD roller conveyor between the fixed rod and the moving rod has a strip-shaped gap for the moving rod to pass through;
[0011] The movable rod is mounted on the first drive device, which is used to drive the movable rod to move up and down.
[0012] Furthermore, a vertical strip space is provided in the middle of the column;
[0013] The two ends of the fixing rod are respectively fixed in two strip spaces;
[0014] The two ends of the moving rod are located in two strip spaces respectively.
[0015] Furthermore, the bottom of the strip space has a support rod, which is located below the movable rod.
[0016] Furthermore, the top of the strip space also has a support rod, which is located above the fixed rod and is fixedly connected to the fixed rod.
[0017] Furthermore, both the fixed rod and the movable rod are round rods or round tubes.
[0018] Furthermore, the tops of the two columns are connected by a crossbeam;
[0019] Each column is equipped with a base plate (170) at its bottom;
[0020] The first drive unit is mounted on the crossbeam or base plate (170).
[0021] Furthermore, the distance between the fixed rod and the exit of the CD roller conveyor is less than or equal to the length of the steel and greater than the length of the short steel.
[0022] Another technical solution of this utility model: a non-standard length steel sorting system, including a non-standard length steel sorting device according to any one of the above-mentioned claims;
[0023] It also includes a baffle installed at the exit of the CD roller conveyor, which extends from one side of the CD roller conveyor to the other side and can move up and down relative to the CD roller conveyor.
[0024] Furthermore, a second drive device is provided on the top of the baffle.
[0025] Furthermore, a cold shear is installed at the entrance of the CD roller conveyor.
[0026] The beneficial effects of this utility model are as follows: By setting a fixed rod and a movable rod on the CD roller conveyor, when the short steel piece on the CD roller conveyor passes under the fixed rod and the fixed steel piece does not pass under the fixed rod, the movable rod moves from bottom to top toward the fixed rod, thereby driving the fixed steel piece to move toward the fixed rod until the fixed rod and the movable rod clamp the fixed steel piece, thus realizing the sorting of fixed steel piece and short steel piece.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0037] This utility model discloses a non-standard length steel sorting device, such as... Figure 1 and Figure 2As shown, the CD roller conveyor 400 includes columns 150 respectively disposed on both sides of the CD roller conveyor 400; a horizontal fixing rod 130 is disposed between the two columns 150, extending from one side of the CD roller conveyor 400 to the other side, and the fixing rod 130 is higher than the roller body of the CD roller conveyor 400; it also includes a movable rod 140, which is arranged parallel to the fixing rod 130 and located directly below the fixing rod 130 (i.e., the two intersect in the horizontal direction); a strip-shaped gap is opened on the guard plate of the CD roller conveyor 400 between the fixing rod 130 and the movable rod 140 for the movable rod 140 to pass through; the movable rod 140 is mounted on a first driving device, which is used to drive the movable rod 140 to move up and down. The roller body is the main part of the CD roller conveyor 400 in which the rollers participate in transporting materials.
[0038] This invention uses a fixed rod 130 and a movable rod 140 on a CD roller conveyor 400. When a short piece of steel on the CD roller conveyor 400 passes below the fixed rod 130 while a piece of steel of a fixed length does not, the movable rod 140 moves upward toward the fixed rod 130, causing the piece of steel of a fixed length 500 to move toward the fixed rod 130 until the fixed rod 130 and the movable rod 140 clamp the piece of steel of a fixed length 500, thus achieving the sorting of the piece of steel of a fixed length 500 and the short piece of steel 600.
[0039] The column 150 has a vertically oriented strip space in its middle; the two ends of the fixed rod 130 are respectively fixed in two strip spaces; the two ends of the movable rod 140 are also located in two strip spaces. By creating strip spaces on the column 150, the movement path of the movable rod 140 can be limited to prevent it from deviating, thereby stably clamping the fixed-length steel 50. Moreover, the fixed rod 130 and the movable rod 140 being in the strip spaces also prevent them from accidentally falling and affecting the normal operation of other equipment.
[0040] Regarding the strip space, it can also be formed by two sub-columns arranged side by side to form column 150, which can eliminate the need to process the strip space and reduce the processing difficulty.
[0041] The bottom of the strip-shaped space has a support rod 160, which is located below the movable rod 140. The support rod 160 is designed to support the movable rod 140, facilitating disassembly or replacement of the movable rod 140.
[0042] The top of the strip-shaped space has a support rod 160, which is located above and fixedly connected to the fixed rod 130. Since the moving rod 140 applies force by moving upwards, a higher degree of stability is required for the fixed rod 130. Therefore, adding the support rod 160 in the direction of force application to the fixed rod 130 can make the fixed rod 130 more stable.
[0043] The support rod 160 can take many forms, such as plate, rod, groove, etc., or even non-standard shapes, all based on stability.
[0044] In this invention, both the fixed rod 130 and the movable rod 140 are round rods or tubes. This ensures that their contact points are tangent, forming a clamping line similar to chopsticks, providing greater clamping force and effectively preventing the fixed-length steel 500 from being carried away by the CD roller conveyor 400 due to insufficient or uneven clamping force.
[0045] In addition, a soft pad is provided on the clamping area of the fixed rod 130 and the moving rod 140 to prevent the clamping area of the fixed rod 130 and the moving rod 140 from damaging the threads on the surface of steel materials such as threaded steel bars during clamping.
[0046] The tops of the two uprights 150 are connected by a crossbeam 110; each upright 150 has a base plate 170 at its bottom; the first drive unit is mounted on either the crossbeam 110 or the base plate 170. The crossbeam 110 and the base plate 170 increase the structural stability of the sorting device. When the first drive unit is mounted on the crossbeam 110, its output shaft faces downwards; when the first drive unit is mounted on the base plate 170, its output shaft faces upwards. Relatively speaking, mounting the first drive unit on the base plate 170 is safer, but due to the presence of the CD roller conveyor 400, the base plate 170 may not be suitable for installation, in which case it can be mounted on the crossbeam 110.
[0047] It should be noted that the distance between the fixed rod 130 and the exit of the CD roller conveyor 400 is less than or equal to the length of the fixed-length steel 500 and greater than the length of the short-length steel 600. Since the steel is passively moved on the CD roller conveyor 400 at the same speed, the front ends of both the fixed-length steel 500 and the short-length steel 600 are flush. This is because they are formed simultaneously by cold shearing. Therefore, when the fixed-length steel 500 and the short-length steel 600 move simultaneously and their front ends are flush, the difference lies in their rear ends; the rear end of the fixed-length steel 500 is further back than the rear end of the short-length steel 600.
[0048] Therefore, by limiting the length as described above, it can be ensured that the fixed rod 130 and the moving rod 140 clamp the fixed length of steel 500 each time, thereby achieving the separation of the two.
[0049] This utility model also discloses a non-standard length steel sorting system, including the aforementioned non-standard length steel sorting device; it also includes a baffle 310 disposed at the exit of the CD roller conveyor, the baffle 310 extending from one side of the CD roller conveyor 400 to the other side, and the baffle 310 being movable up and down relative to the CD roller conveyor 400.
[0050] When the baffle 310 falls, its lower end is at the same height as the CD roller conveyor 400, which can block the fixed-length steel 500 and short-length steel 600 moving from the direction of the sorting device. This results in the front end of the steel in the same batch being blocked by the baffle 310, creating a distance difference between the rear ends of the two types of steel. This allows the fixed rod 130 and the moving rod 140 to clamp the rear ends of the fixed-length steel 500. Then, when the baffle 310 rises, the short-length steel 600 will continue to move forward from below the baffle 310, thus achieving the sorting of the two types of steel.
[0051] In this invention, since the baffle 310 is located above the CD roller conveyor 400, a second driving device is provided on the top of the baffle 310. This avoids occupying space in the CD roller conveyor 400. It should be noted that both the first and second driving devices can be selected as needed. For example, in this application, the first driving device is selected as the first cylinder 120, and the second driving device is selected as the second cylinder 300.
[0052] In addition, a cold shear 200 is installed at the entrance of the CD roller conveyor 400. The cold shear 200 can cut steel into fixed length steel 500 or short length steel 600.
[0053] The following will be based on Figures 3-7 The detailed working process of this utility model is described and explained.
[0054] like Figure 3 and Figure 4 As shown, the column 150 is made of 14# channel steel, and the crossbeam 110 is made of steel plate with dimensions of 3850mm × 300mm × 30mm. The sorting device has a height of 1740mm and a span of 2550mm. Both cylinders are model QGBZ 125-250-MPI, with a stroke of 250mm and a cylinder diameter of 125mm. The fixed rod 130 is made of φ90mm steel pipe, with a length of 2600mm, and is welded and fixed to the column 150, providing a solid fixed support for the device. The moving rod 140 is made of φ90mm steel pipe, with a length of 3400mm, and can move flexibly under the drive of the cylinders.
[0055] Uncut steel is transported from the cooling bed to the cold shear 200, where it is sheared to a pre-set size. Because the steel entering the cold shear 200 varies in length and at different times, some steel is at the beginning or end during shearing, resulting in short-length steel pieces 600 after shearing.
[0056] After the cold shearing 200 is completed, as follows: Figure 3 and Figure 4As shown, the fixed-length steel 500 and the short-length steel 600 move forward under the drive of the CD roller conveyor 400. When the front ends of these steel pieces approach the outlet of the CD roller conveyor 400, the baffle 310 falls under the drive of the second cylinder 300, blocking the front ends of these steel pieces and aligning them. This is because the fixed-length steel 500 and the short-length steel 600 have different lengths, and the tail ends of the two types of steel pieces are also in different positions. The tail end of the fixed-length steel 500 is after the sorting device, and the tail end of the short-length steel is before the sorting device.
[0057] Next, the first cylinder 120 is activated, causing the moving rod 140 to move upward, simultaneously raising the tail end of the fixed-length steel 500 until the moving rod 140 and the fixed rod 130 clamp the tail end of the fixed-length steel 500. Figure 5 and Figure 6 As shown, at this point, the tail end of the short steel bar 600 is not clamped.
[0058] Then, as Figure 7 As shown, the baffle 310 is raised by the second cylinder 300, and the short steel bar 600 continues to move forward under the drive of the CD roller conveyor 400. The fixed steel bar 500 remains in the same position because its tail end is clamped. After the short steel bar 600 enters the collection area, the first cylinder 120 is driven to move the moving rod 140 downward, and the fixed steel bar 500 continues to move forward under the drive of the CD roller conveyor 400.
[0059] In this way, it can be ensured that the fixed-length steel (500 mm) and short-length steel (600 mm) enter the steel collection area in batches, thus realizing the sorting of the fixed-length steel (500 mm) and short-length steel (600 mm).
[0060] This invention adds an independent mechanical component to existing production line equipment. This component is specifically designed for steel separation tasks, eliminating the need for a complex electronic control system and simplifying the overall structure. Utilizing precise cylinder control, it achieves automatic lifting, clamping, and separation of the steel, a crucial action for improving separation efficiency and accuracy. The device design emphasizes simplicity, making it easy to integrate into existing production lines and facilitating installation and operation. Due to its simple structure, manufacturing and maintenance costs are relatively low, resulting in a high cost-effectiveness ratio. The device can adapt to production lines for different specifications of bar stock, exhibiting excellent versatility and flexibility. The simplified design also means easier maintenance and reduced long-term operating costs.
