Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, and more specifically, to an automatic steel strip separating and anti-reverse device. Background Technology

[0002] In the construction and metal processing industries, steel bars are a critical material, making their efficient processing extremely important. Traditional manual or semi-automatic steel bar sorting methods suffer from low efficiency, high labor intensity, and susceptibility to counting errors. With the increasing demand for automation in the industry, the requirements for automation and precision in steel bar sorting and conveying equipment are constantly rising. The automatic steel bar sorting and anti-backward device has emerged to address this need. Through the coordinated operation of components such as the base, guiding mechanism, anti-backward mechanism, and conveyor belt, it solves the problems of orderly conveying, precise separation, stable transmission, and accurate counting of steel bars, providing an effective technical solution for improving steel bar processing efficiency and quality while reducing labor costs.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: Most existing devices use mechanical baffles or simple cylinder-driven separation, lacking a precise transmission system with servo motors and lead screws, resulting in large deviations in the movement position of the push plate, which easily leads to the stacking of reinforcing bars or uneven separation spacing. The front end of the separating components (such as the insertion rod) is mostly designed with right angles or flat surfaces, which easily causes hard collisions when inserted into the gaps between reinforcing bars, resulting in scratches or jamming on the surface of the reinforcing bars, especially when dealing with large-diameter reinforcing bars.

[0004] Therefore, an automatic strip-separating anti-backward device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic steel strip separating and anti-backward device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic bar-separating anti-backward device, comprising a base, a guiding mechanism at the top of the base, an anti-backward mechanism on one side of the guiding mechanism, and a conveyor belt at the bottom of the guiding mechanism; the guiding mechanism includes a guiding component for guiding the bars one by one to the top of the conveyor belt and a separating component for separating adjacent bars, the separating component including a bearing seat fixedly installed on the top of the base, a servo motor for driving the lead screw to rotate, a lead screw threadedly connected to the lead screw for driving the push plate to move back and forth, and a push plate for separating the upper and lower bars, an insert rod fixedly connected to one side of the push plate, the insert rod passing through a pre-reserved limiting groove in the guide seat, and a streamlined guiding slope at the front end of the insert rod, the lead screw converting the rotational motion of the servo motor into the linear motion of the push plate, controlling the movement accuracy and stroke of the push plate.

[0007] Preferably, the guiding mechanism includes guide seats fixedly installed on the left and right sides of the base, a guide plate fixedly installed on one side of the guide seat slope for guiding the reinforcing bars to roll down to the top of the conveyor belt, and a side plate for cooperating with the insert rod and the guide seat to form a waiting area. The guide seat includes two symmetrically installed guide blocks on the left and right, and the top of each guide block is provided with a slope for guiding the reinforcing bars to roll down. The insert rod passes through the guide seat limiting groove and is linked with the push plate. The streamlined guide slope at the front end guides the reinforcing bars to move smoothly and avoid jamming.

[0008] Preferably, the anti-backflow mechanism includes a positioning seat fixedly installed on the top of the base. The positioning seats are symmetrically arranged on the left and right sides of the conveyor belt. A one-way guide plate is hinged to the top of each positioning seat. The one-way guide plate is normally inclined. A spring is provided between the one-way guide plate and the positioning seat. One end of the spring is fixedly connected to the positioning seat, and the other end of the spring is fixedly connected to the one-way guide plate. The one-way guide plate is normally inclined, allowing the reinforcing bar to move towards the end of the conveyor belt and preventing the reinforcing bar from flowing back. The smooth wear-resistant layer near the side of the conveyor belt can reduce the friction loss of the reinforcing bar.

[0009] Preferably, the anti-reverse mechanism further includes a laser counter positioning frame fixedly installed on the top of the positioning seat, and a laser counter body is fixedly installed on the top of the laser counter positioning frame, with the laser counter body positioned directly above the conveyor belt.

[0010] Preferably, a limiting post is fixedly connected to one side of the push plate, and the limiting post is movably connected to a guide groove opened on one side of the bearing seat.

[0011] Preferably, the guide plate is an arc-shaped plate that matches the curvature of the guide seat slope, and its extension direction points towards the feed end of the conveyor belt.

[0012] Preferably, the unidirectional guide plate has a smooth and wear-resistant layer on the side near the conveyor belt, and its inclination angle is an acute angle with the direction of steel bar conveying.

[0013] Preferably, a linear bearing is provided between the limiting post and the guide groove of the bearing seat.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with existing technologies, this automatic steel bar separating and anti-backward device, through the inclusion of components such as a servo motor, lead screw, push plate, insert rod, and guide seat, utilizes the driving relationship between the servo motor and the lead screw to control the forward and backward movement of the push plate via threaded transmission, thereby driving the insert rod to slide within the limiting groove of the guide seat. The streamlined guide slope at the front end of the insert rod, in conjunction with the slope of the guide seat and the arc trajectory of the guide plate, can separate stacked steel bars into individual pieces, guiding them sequentially to the top of the conveyor belt. This structure, through the synergistic effect of mechanical transmission and guiding limitation, achieves the effect of orderly separation and precise conveying of the screened steel bars, avoiding the jamming or chaos caused by stacked steel bar conveying.

[0016] 2. Compared with existing technologies, this automatic steel bar separation anti-backflow device for the steel bar sorting machine utilizes components such as a positioning seat, a unidirectional guide plate, springs, a laser counter positioning frame, and a laser counter body. Through the hinged connection between the positioning seat and the unidirectional guide plate, the unidirectional guide plate maintains a constant tilt angle due to the elastic tension of the springs, thus creating a unidirectional anti-backflow barrier for the steel bars on the conveyor belt. When the steel bars are conveyed forward, the guide plate is pushed open, and the rear guide plate resets under the action of the springs, preventing the steel bars from flowing back. Simultaneously, the laser counter body is fixed directly above the conveyor belt by the positioning frame, counting the passing steel bars in real time. This design, through the combination of a mechanical anti-backflow structure and a laser counting system, achieves the effects of anti-backflow control and automated, accurate counting of the screened steel bars, improving the reliability and production efficiency of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 The automatic steel bar separating and anti-backflow device shown includes a base 1, with a guiding mechanism 2 on the top of the base 1. The guiding components of the guiding mechanism 2 include guide seats 206 fixedly installed on the left and right sides of the base 1, a guide plate 207 fixedly installed on one side of the slope of the guide seat 206 for guiding the steel bars to roll onto the top of the conveyor belt 4, and a side plate 208 for forming a waiting area with the insert rod 209 and the guide seat 206. The guide seat 206 includes two symmetrically installed guide blocks, and the top of each guide block is provided with a ramp for guiding the steel bars to roll down. The ramp design of the guide seat 206 allows the steel bars to roll smoothly along a preset path. The guide plate 207 further regulates the movement trajectory of the steel bars. The waiting area formed by the side plate 208 and the insert rod 209 can temporarily store the steel bars, ensuring that the steel bars enter the conveyor belt 4 in an orderly manner.

[0025] like Figure 2 and Figure 3 As shown, the guiding mechanism 2 includes a guiding assembly for guiding the reinforcing bars one by one to the top of the conveyor belt 4 and a separating assembly for separating adjacent reinforcing bars. The separating assembly includes a bearing seat 201 fixedly installed on the top of the base 1, a servo motor 202 for driving the lead screw 203 to rotate, a lead screw 203 threadedly connected to the lead screw 203 for driving the push plate 204 to move back and forth, and a push plate 204 for separating the upper and lower reinforcing bars. A rod 209 is fixedly connected to one side of the push plate 204. The rod 209 passes through the limiting groove reserved in the guide seat 206, and the front end of the rod 209 has a streamlined guiding slope. The servo motor 202 drives the lead screw 203 to drive the push plate 204 to reciprocate. The push plate 204 separates the stacked reinforcing bars one by one through the rod 209. The streamlined guiding slope reduces the resistance to the movement of the reinforcing bars, ensuring that only a single reinforcing bar is pushed to the conveyor belt 4 at a time.

[0026] like Figures 2 to 4As shown, a limiting post 205 is fixedly connected to one side of the push plate 204. The limiting post 205 is movably connected to a guide groove opened on one side of the bearing seat 201. The guide plate 207 is an arc-shaped plate that matches the curvature of the slope surface of the guide seat 206, and its extension direction points to the feeding end of the conveyor belt 4. A linear bearing is provided between the limiting post 205 and the guide groove of the bearing seat 201. The limiting post 205 and the linear bearing cooperate to ensure that the push plate 204 moves smoothly without deviation. The arc-shaped guide plate 207 fits against the slope surface of the guide seat 206, accurately guiding the steel bars to roll down to the feeding end of the conveyor belt 4, improving the accuracy and stability of steel bar conveying.

[0027] like Figure 1 and Figure 3 As shown, a backstop mechanism 3 is provided on one side of the guiding mechanism 2, and a conveyor belt 4 is provided at the bottom of the guiding mechanism 2. The backstop mechanism 3 includes a positioning seat 301 fixedly installed on the top of the base 1. The positioning seats 301 are symmetrically arranged on the left and right sides of the conveyor belt 4. A one-way guide plate 302 is hinged to the top of each positioning seat 301. The one-way guide plate 302 is normally inclined. A spring 303 is provided between the one-way guide plate 302 and the positioning seat 301. One end of the spring 303 is fixedly connected to the positioning seat 301, and the other end of the spring 303 is fixedly connected to the one-way guide plate 302. The one-way guide plate 302 is kept inclined under the action of the spring 303, allowing the steel bars to pass smoothly in the conveying direction and preventing them from sliding backward, effectively preventing the backflow of steel bars, ensuring stable one-way conveying of the conveyor belt 4, and avoiding the accumulation or backflow of steel bars during the conveying process.

[0028] like Figure 2 and Figure 3 As shown, the anti-reverse mechanism 3 also includes a laser counter positioning frame 304 fixedly installed on the top of the positioning seat 301. A laser counter body 305 is fixedly installed on the top of the laser counter positioning frame 304. The laser counter body 305 is positioned directly above the conveyor belt 4. The unidirectional guide plate 302 has a smooth and wear-resistant layer on the side near the conveyor belt 4, and its tilt angle is an acute angle with the direction of rebar conveying. The laser counter body 305 monitors the number of rebars on the conveyor belt 4 in real time, providing accurate data for the counting machine. The smooth and wear-resistant layer reduces frictional wear between the unidirectional guide plate 302 and the rebars, and the acute tilt angle ensures smooth rebar passage, improving the overall durability and counting accuracy of the device.

[0029] Example

[0030] Rebar sorting and counting scenario

[0031] On the steel bar production line of a steel processing company, the produced steel bars need to be sorted and accurately counted for subsequent packaging and sales. At this stage, the automatic steel bar sorting and anti-backflow device plays a crucial role.

[0032] First, the steel bars to be sorted are stacked in a stacking area adjacent to the base 1. The steel bars roll down onto the guide seat 206 of the guiding mechanism 2 under their own weight or external pushing force. The guide seat 206 consists of two symmetrically installed guide blocks, each with a ramp at its top to guide the steel bars as they slide down naturally. A guide plate 207, an arc-shaped plate matching the curvature of the guide seat 206's slope, is fixedly installed on one side of the slope, extending towards the feed end of the conveyor belt 4, precisely guiding the steel bars to the top of the conveyor belt 4.

[0033] During the rebar rolling process, in order to ensure that the rebars move to the conveyor belt 4 in an orderly manner, the separating component starts to work. The servo motor 202, which is fixedly installed on the bearing seat 201 on the top of the base 1, starts and drives the lead screw 203 to rotate. The push plate 204, which is threadedly connected to the lead screw 203, moves back and forth under the drive of the lead screw 203. The limiting post 205, which is fixedly connected to one side of the push plate 204, is movably connected to the guide groove opened on one side of the bearing seat 201, and a linear bearing is set between the limiting post 205 and the guide groove of the bearing seat 201 to ensure the stability and smoothness of the movement of the push plate 204. The insert rod 209 is fixedly connected to the other side of the push plate 204. The insert rod 209 passes through the limiting groove reserved in the guide seat 206, and the front end of the insert rod 209 has a streamlined guide slope. As the push plate 204 moves forward, the guide slope of the insert rod 209 can separate the stacked upper and lower reinforcing bars, allowing the reinforcing bars to enter the waiting area formed by the side plate 208, the insert rod 209 and the guide seat 206 one by one, and then move accurately to the top of the conveyor belt 4, avoiding congestion and chaos of the reinforcing bars.

[0034] After the conveyor belt 4 starts, it transports the reinforcing bars forward. At this time, the anti-reverse mechanism 3 begins to function. The positioning seats 301, which are fixedly installed on the top of the base 1 and symmetrically arranged on the left and right sides of the conveyor belt 4, have a one-way guide plate 302 hinged to its top. Under the action of the spring 303, the plate is normally tilted, and the tilt angle is an acute angle with the direction of reinforcing bar transportation. The side of the one-way guide plate 302 closest to the conveyor belt 4 has a smooth wear-resistant layer. When the reinforcing bar moves forward with the conveyor belt 4, the reinforcing bar pushes the one-way guide plate 302 to rotate around the hinge point of the positioning seat 301, and the spring 303 is stretched, allowing the reinforcing bar to pass smoothly. When the reinforcing bar tends to slide backward due to a short pause of the conveyor belt 4 or other reasons, the one-way guide plate 302, under the tension of the spring 303, tightly presses against the reinforcing bar, preventing it from moving backward and ensuring that the reinforcing bar can only move in the direction of transportation.

[0035] Meanwhile, a laser counter positioning frame 304, fixedly installed on top of the positioning base 301, has a laser counter body 305 positioned directly above the conveyor belt 4 to count the passing steel bars in real time. Each time a steel bar passes the laser counter body 305, the counter records the count, thus accurately determining the number of steel bars on the conveyor belt 4 and providing precise data support for subsequent sorting and packaging.

[0036] The implementation principle of the automatic steel strip separating and anti-backward device of this application embodiment is as follows:

[0037] First, the steel bars to be processed are stacked on top of the guide mechanism 2. Using the sloping structure at the top of the guide seat 206, the steel bars automatically roll down the slope to the guide plate 207. The guide plate 207 is an arc-shaped plate that matches the curvature of the slope of the guide seat 206. Its extension direction is precisely pointed to the feed end of the conveyor belt 4. The steel bars are guided to slide along the preset path through the arc trajectory and enter the waiting area formed by the side plate 208, the insert rod 209 and the guide seat 206, completing the initial positioning and orientation calibration of the steel bars, and preparing for subsequent separation.

[0038] Secondly, after the servo motor 202 starts, it drives the lead screw 203 to rotate, which drives the push plate 204 to move back and forth along the guide groove of the bearing seat 201 through the threaded transmission. The insertion rod 209 on one side of the push plate 204 moves synchronously with the push plate 204. The streamlined guide slope at its front end is inserted into the gap of the stacked steel bars, forcibly separating the upper layer of steel bars from the lower layer of steel bars. The limiting post 205 cooperates with the linear bearing in the guide groove of the bearing seat 201 to ensure the stability and accuracy of the movement of the push plate 204. Each action only allows a single steel bar to pass through the waiting area and fall into the conveyor belt 4 below, avoiding the stacking and conveying of multiple steel bars.

[0039] Next, after the conveyor belt 4 starts, it drives the single steel bar to move towards the discharge end. When the steel bar contacts the one-way guide plate 302 of the anti-reverse mechanism 3, since the tilt angle of the guide plate is at an acute angle to the steel bar conveying direction, and the forward force of the steel bar is greater than the tension of the spring 303, the guide plate rotates around the hinge point of the positioning seat 301, allowing the steel bar to pass. After the steel bar passes, the restoring force of the spring 303 makes the guide plate quickly return to the tilted state, forming a reverse blocking surface to prevent the steel bar from flowing back due to the fluctuation of the conveyor belt 4 or the action of external force, ensuring stable one-way conveying of the steel bar. The smooth wear-resistant layer on the surface of the guide plate can reduce the frictional resistance with the steel bar and improve the durability of the mechanism.

[0040] Next, directly above the conveyor belt 4, the laser counter body 305, fixedly installed on the laser counter positioning frame 304, continuously emits a laser beam. When the steel bar passes through the laser beam area with the conveyor belt 4, the steel bar blocks the laser signal. The counter body captures the signal change in real time and records the number of times. This counting process is synchronized with the steel bar conveying and does not require additional manual intervention. Combined with the one-way anti-reverse function of the anti-backflow mechanism 3, it ensures that each passing steel bar is accurately counted, avoiding counting errors caused by backflow or repeated conveying.

[0041] Finally, through the ramp guidance of the guiding mechanism 2, the single-strand separation of the separating component, the continuous conveying of the conveyor belt 4, the one-way blocking of the anti-reverse mechanism 3, and the real-time counting of the laser counter, the components form a closed-loop working system. The steel bars start from the stacked state and go through the guiding, separating, conveying, anti-reverse, and counting stages to finally achieve automated strip picking. The entire process does not require manual intervention and effectively solves the problems of steel bar stacking jamming and backflow and missed counting in traditional strip picking machines. It significantly improves the efficiency and accuracy of steel bar sorting and is suitable for the high-efficiency operation requirements of industrial production lines.
