Description

Technical Field

[0001] This utility model belongs to the technical field of binding equipment, specifically relating to an automatic rebar binding device. Background Technology

[0002] During building or bridge construction, rebar tying is required, and currently it is still done manually. Workers use tying tools or handheld tying machines to complete the tying. However, this method is inefficient and labor-intensive due to the large scale of construction projects. While there are now some automated tying machines available, these are bulky, complex in structure, and expensive. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic rebar tying device to address the problems of existing technologies.

[0004] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows: An automatic rebar tying device includes a frame, on which a longitudinal moving mechanism is provided to drive the device to move along the longitudinal rebars of a rebar mesh. The frame is also equipped with a lifting mechanism, on which multiple automatic rebar tying machines are arranged at equal intervals in the transverse direction. A position sensor is provided on the frame corresponding to the automatic rebar tying machine in the transverse direction to detect the position of the transverse rebar. The position sensor is connected to a controller, which is connected to the longitudinal moving mechanism, the automatic rebar tying machines, and the lifting mechanism.

[0005] As a preferred embodiment, the longitudinal movement mechanism includes rotatably mounted wheels at the bottom of the frame. The outer side of each wheel has a V-shaped travel groove. A drive shaft connects the two ends of the wheels on one side, and the drive shaft is connected to a travel drive mechanism. The arrangement of the wheels and the V-shaped travel groove allows the device to be placed on top of the longitudinal reinforcing bars of a steel mesh, move along the longitudinal reinforcing bars, and accommodate longitudinal reinforcing bars of various sizes.

[0006] As a preferred embodiment, the walking drive mechanism includes a driven pulley fixed on the drive shaft, a driving pulley connected to the driven pulley via a synchronous belt, and a walking motor fixedly connected to the driving pulley. The walking motor is fixed to the frame. When the walking motor starts, it drives the drive shaft to rotate via the driving pulley, synchronous belt, and driven pulley, thereby causing the walking wheels to roll along the longitudinal reinforcing bars.

[0007] As a preferred embodiment, a central support wheel is rotatably mounted in the middle of the frame, and a V-shaped travel groove is provided on the outer wall of the central support wheel. This provides support for the front and rear of the device in the middle, making movement more stable.

[0008] As a preferred embodiment, an outer shell is fixed to the outer side of the frame, and a handle connecting the frame is fixed to the upper part of the outer shell to facilitate lifting the device.

[0009] As a preferred embodiment, the top of the outer casing is equipped with a pusher for fixing the frame, which allows the device to be easily moved manually.

[0010] As a preferred embodiment, the lifting mechanism includes a linear module 1 vertically mounted on the frame, a mounting plate 1 connected to the linear module 1, and multiple connecting plates fixed at equal intervals along the horizontal direction on the mounting plate 1. A fixed frame is flexibly connected to the bottom of the outer end of the connecting plates. The automatic rebar tying machine is vertically fixed on the fixed frame. The lifting of the linear module 1 can drive the automatic rebar tying machine mounted on the fixed frame to lift and move closer to or away from the tying position.

[0011] As a preferred embodiment, a buffer rubber column is provided between the fixed frame and the connecting plate. Connecting screws are fixed to the top and bottom of the buffer rubber column. The upper and lower connecting screws pass through the connecting plate and the fixed frame respectively and are connected to locking nuts. Each of the upper and lower connecting screws has a positioning boss integrated with the buffer rubber column. A vertical guide rail is provided on the frame, and a slider is mounted on the guide rail. The slider is fixed to the mounting plate. By providing a buffer rubber column between the fixed frame and the connecting plate, vibration damping is achieved, and a flexible connection is realized, allowing for a certain amount of elasticity at the bottom of the automatic rebar tying machine, making it less prone to jamming.

[0012] As a preferred embodiment, the lifting mechanism includes a second linear module that is inclined at an angle between the horizontal and vertical directions. The second linear module is connected to a second mounting plate, and the automatic rebar tying machine is vertically fixed on the second mounting plate.

[0013] As a preferred embodiment, a hanging plate is fixed to the frame, and a fixed plate is fixed to the bottom of the hanging plate. The fixed plate is inclined at the angle between the vertical and longitudinal directions. The second linear module is fixed to the fixed plate, and an inclined guide rail is fixed to the fixed plate. The guide rail has a slider, which is fixed to the mounting plate. The lifting mechanism drives the automatic rebar tying machine to descend and tie the rebars at a 45-degree spatial trajectory, preventing the lower end of the automatic rebar tying machine from getting stuck at the intersection of the rebars.

[0014] The advantages of this utility model compared with the prior art are: The longitudinal moving mechanism can drive the device to move along the longitudinal bars of the steel mesh. Then, the position sensor detects the position of the transverse bars. When it reaches the intersection of the transverse and longitudinal bars, it can stop. Then, the lifting mechanism lifts and lowers the automatic steel bar tying machine to automatically tie the steel bars. Multiple steel bar nodes can be tied in one descent, which improves tying efficiency, reduces labor intensity, and has a simple structure and low cost. Attached Figure Description

[0016] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1, Reference Figures 1 to 3 An automatic rebar tying device is characterized by comprising a frame 14, on which a longitudinal moving mechanism is provided to drive the device to move along the longitudinal rebar of the rebar mesh, and a lifting mechanism is also provided on the frame 14. The lifting mechanism is provided with a plurality of automatic rebar tying machines 3 arranged at equal intervals in the transverse direction. A position sensor 6 is provided on the frame 14 corresponding to the automatic rebar tying machine 3 in the transverse direction to detect the position of the transverse rebar. The position sensor 6 is connected to a controller, and the controller is connected to the longitudinal moving mechanism, the automatic rebar tying machine 3 and the lifting mechanism.

[0018] When tying reinforcing bars, since the horizontal and vertical spacing of the reinforcing mesh is fixed, we designed this device. During operation, the device is placed on the vertical reinforcing bars of the mesh. The vertical moving mechanism drives the device to move along the vertical reinforcing bars. At this time, the position sensor 6 detects the position of the horizontal reinforcing bars. Upon detecting the position signal of the horizontal reinforcing bars, it sends a signal to the controller. The controller stops the vertical moving mechanism and then controls the lifting mechanism to lower the automatic reinforcing bar tying machine 3 to the tying position for automatic tying. After tying is completed, the lifting mechanism rises, and the vertical moving mechanism continues to move to the next tying position. Alternatively, if the horizontal reinforcing bars are above the vertical reinforcing bars, the device can also be placed on the horizontal reinforcing bars and moved along them to detect the position of the vertical reinforcing bars.

[0019] Example 2, based on Example 1, such as Figures 1 to 4 As shown, the longitudinal movement mechanism includes a traveling wheel 2 rotatably mounted on the bottom of the frame 14. The outer side wall of the traveling wheel 2 is provided with a V-shaped traveling groove. A drive shaft 15 is connected between the two ends of the traveling wheel 2 on one side, and the drive shaft 15 is connected to the traveling drive mechanism. The traveling wheel 2 is made of stainless steel and is covered with a polyurethane layer.

[0020] The walking drive mechanism includes a driven pulley 16 fixed on the drive shaft 15. The driven pulley 16 is connected to a driving pulley via a synchronous belt. The driving pulley is fixedly connected to a walking motor 18, which is fixed to the frame 14. The walking motor 18 is a servo motor. The controller is a PLC controller, such as a Siemens ST40. The position sensor 6 is a metal proximity switch.

[0021] A central support wheel 17 is rotatably mounted in the middle of the frame 14, and a V-shaped traveling groove is provided on the outer side wall of the central support wheel 17. At this time, the automatic rebar tying machine 3 can use the RT-441 fully automatic rebar tying machine.

[0022] An outer shell 1 is fixed to the outer side of the frame 14, and a lifting handle 4 connected to the frame 14 is fixed to the upper part of the outer shell 1. After the walking drive mechanism moves the device from one end of the longitudinal steel bar to the other end, it can be manually lifted by the lifting handle 4 for lateral transfer. An operation panel is provided on the outer shell 1, which is connected to a controller. The outer shell is provided with power, binding, forward, backward, and start buttons connected to the controller.

[0023] The top of the outer casing 1 is equipped with a push handle 5 for fixing the frame 14. It can be manually moved by pushing the push handle.

[0024] The lifting mechanism includes a linear module 12 vertically mounted on the frame 14. The linear module 12 is connected to a mounting plate 11. Multiple connecting plates 10 are fixed at equal intervals along the horizontal direction on the mounting plate 11. A fixing frame 7 is flexibly connected to the bottom of the outer end of the connecting plate 10. The automatic rebar binding machine 3 is vertically fixed on the fixing frame 7.

[0025] A buffer rubber column 8 is provided between the fixed frame 7 and the connecting plate 10. The top and bottom of the buffer rubber column 8 are fixed with connecting screws 9. The upper and lower connecting screws 9 pass through the connecting plate 10 and the fixed frame 7 respectively and are connected with locking nuts. The upper and lower connecting screws 9 are provided with positioning bosses 25 that are integrated with the buffer rubber column 8. The frame 14 is provided with a vertical guide rail 13. A slider is provided on the guide rail 13. The slider is fixed to the mounting plate 11.

[0026] Example 3 differs from Example 2 in that, as Figures 5 to 8 As shown, the lifting mechanism includes a linear module 219 inclined at the angle between the horizontal and vertical directions. The linear module 219 is connected to a mounting plate 20, and the automatic rebar tying machine 3 is vertically fixed on the mounting plate 20.

[0027] A hanging plate 23 is fixed on the frame 14, and a fixing plate 22 is fixed to the bottom of the hanging plate 23. The fixing plate 22 is inclined at an angle between the vertical and longitudinal directions, preferably 45 degrees. The linear module 19 is fixed on the fixing plate 22, and an inclined guide rail 21 is fixed on the fixing plate 22. The fixing plate 22 is inclined at a 45-degree angle, and a slider 2 is provided on the guide rail 21. The slider 2 is fixed to the mounting plate 20. At this time, the automatic rebar tying machine 3 can be a fully automatic rebar tying machine of model 8-34.

[0028] Automatic binding is possible. Pressing the "Start" button sends a start signal to the controller, which then sends a forward signal and a pulse signal to the walking motor 18. The device moves forward a set distance along the longitudinal reinforcing bars. Position sensors 6 on both sides detect the reinforcing bars and send a position signal to the controller. The controller then sends a stop signal to the walking motor 18, causing it to stop moving and the reinforcing bar binding machine to stop advancing. If both position sensors 6 detect the reinforcing bars within a certain range, the device is in position. The display receives the controller signal and shows "Equipment in position" on the automatic interface. The controller then sends a binding signal to execute the binding action. If neither position sensor 6 detects the reinforcing bars within a certain range, the device is not in position. The display receives the controller signal and shows "Equipment not in position" on the automatic interface. Manual adjustment using the forward and backward buttons is required until the display shows "Equipment in position." The controller then sends a binding signal to execute the binding action. During the binding action, the controller simultaneously triggers multiple automatic rebar binding machines 3 to descend synchronously to the set height and reach the working position. After receiving the arrival signal, the controller triggers timer T1 and sends a working signal to the automatic rebar binding machines 3 to bind the rebars. Once the automatic rebar binding machines 3 complete the binding, timer T1 ends. After timer T1 ends, the controller triggers the automatic rebar binding machines 3 to reset, and the automatic rebar binding machines 3 rise back to the starting position. The controller restarts the automatic rebar binding machines 3, and the binding machines continue to move forward. The above binding steps are repeated until the end of the longitudinal rebar or an emergency stop is triggered. The above steps can also be performed manually by pressing the start, forward, reverse, and binding buttons sequentially.

[0029] When the travel motor 18 is overloaded, the motor driver reports an overcurrent fault. Position sensor 6 loses signal for a set period of time and reports a sensor malfunction warning.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
