Description

Technical Field

[0001] This invention relates to the field of rebar connection technology, and in particular to a rebar wire splicing device and operating method. Background Technology

[0002] In engineering construction, to enhance the strength of the foundation pit walls, steel reinforcement cages are added to the diaphragm wall to restrain the concrete. In existing steel reinforcement cage fabrication processes, for the main or parallel reinforcement bars of the upper and lower mesh panels, domestic manufacturers tend to use connectors to link several bars into a single continuous length, such as... Figure 1 As shown. During on-site splicing, the general on-site wire splicing steps are as follows:

[0003] Manually connect connector 10 to rebar 20;

[0004] Place the first steel bar 20 on the ground, and place the second steel bar 30 at the other end of the connector 10;

[0005] Clamp the second reinforcing bar 30 at its far end with pipe wrench 40;

[0006] Use pipe wrench 40 to tighten rebar 230 by a few threads to connect it to rebar 120's connector 10;

[0007] Start the motor 50 and rotate the pipe wrench 40, which will cause the second rebar 30 to rotate, while the first rebar 20 and the connector 10 do not rotate.

[0008] The pipe wrench 40 continues to rotate until the first rebar 20 and the second rebar 30 rotate together. At this point, the connection between the first rebar 20 and the second rebar 30 is considered complete.

[0009] The existing wire splicing device has a low degree of automation, cannot detect when the connection is in place and stop automatically, is inconvenient to operate, requires at least two workers, and wastes human and material resources. Summary of the Invention

[0010] The purpose of this invention is to provide a rebar splicing device and operating method, which makes rebar connection more convenient, saves manpower and material resources, improves work efficiency, and can detect the connection status of the connector, with a high degree of automation.

[0011] To achieve this objective, the present invention adopts the following technical solution:

[0012] Rebar splicing device, including:

[0013] Support base;

[0014] Two clamping assemblies are respectively disposed at both ends of the support base along a first direction, and are used to clamp the first steel bar and the second steel bar to be connected respectively;

[0015] The limiting component includes two limiting claws, which are spaced apart on the support base and can move up and down in the vertical direction. A proximity switch is provided on the opposing sides of the two limiting claws. A connector is provided at the rear end of the first reinforcing bar, and the connector can be limited between the two limiting claws.

[0016] A rotating component for rotating the connector to connect the connector to the second reinforcing bar.

[0017] As an optional solution for the rebar splicing device, the rotating assembly includes a main support and a secondary support. The main support is provided with a driving wheel, and the secondary support is provided with a driven wheel. The main support and the secondary support can approach each other to clamp the connector. The drive motor can drive the driving wheel to rotate, so that the connector rotates.

[0018] As an optional solution for the rebar splicing device, there are two driven wheels, which are spaced apart along a second direction, and the connector is supported between the two driven wheels along a first direction.

[0019] As an optional solution for the rebar splicing device, the main support is moved along the second direction by a horizontal cylinder, and the secondary support is raised and lowered along the vertical direction by a first vertical cylinder.

[0020] As an optional solution for the rebar splicing device, the limiting claw is raised and lowered along the vertical direction by a second vertical cylinder.

[0021] As an optional solution for the rebar splicing device, the limiting component further includes two limiting blocks. The limiting blocks are provided with a sliding groove on the side facing the limiting claw. The bottom end of the vertical rod of the limiting claw is connected to the output end of the second vertical cylinder, and the vertical rod is slidably disposed in the sliding groove.

[0022] As an alternative to the rebar splicing device, the clamping assembly includes a drive member and two clamping plates. The drive member is capable of driving the two clamping plates to move closer to or further apart from each other.

[0023] As an optional solution for the rebar splicing device, the driving component is a driving cylinder, and the clamping assembly also includes a fixed gear and two racks. The fixed gear is rotatably mounted on the support base, and the two racks are respectively located on both sides of the fixed gear and mesh with the fixed gear. The two racks are respectively fixedly connected to the two clamping plates, and the output end of the driving cylinder is fixedly connected to one of the clamping plates.

[0024] As an optional solution for the rebar splicing device, it also includes a grating sensor, which is used to detect the positions of the first rebar, the connector and the second rebar, and to detect the quantity of the first rebar and the second rebar.

[0025] A method for splicing reinforcing bars, using the reinforcing bar splicing device described in any of the above schemes, includes the following steps:

[0026] S1: The conveying device conveys the first steel bar. The rear end of the first steel bar is provided with a connector. The first steel bar moves from the front side to the rear side of the support seat along the first direction. When the first steel bar and the connector move to the set position, the limiting claw near the rear side of the support seat rises. The connector stops moving after triggering the proximity switch of the limiting claw on the rear side.

[0027] S2: The clamping assembly near the rear side of the support clamps the first reinforcing bar;

[0028] S3: The conveying device conveys the second reinforcing bar, which moves from the front to the rear of the support seat along the first direction. When the second reinforcing bar reaches the set position, the limiting claw near the front of the support seat rises.

[0029] S4: The clamping assembly near the front side of the support clamps the second reinforcing bar;

[0030] S5: The rotating assembly clamps the connector and rotates the connector. The connector rotates and moves toward the second reinforcing bar, while simultaneously rotating to connect with the second reinforcing bar. When the connector triggers the proximity switch of the limiting claw on the front side, the rotating assembly stops rotating.

[0031] The beneficial effects of this invention are:

[0032] This invention provides a rebar splicing device, comprising a support base, a limiting component, a rotating component, and two clamping components. The two clamping components are respectively disposed at both ends of the support base along a first direction, and are used to clamp a first rebar and a second rebar. The limiting component includes two limiting claws, which can be raised and lowered vertically, and proximity switches are provided on the facing sides of the two limiting claws. When the first rebar moves from the front to the rear of the support base along the first direction, the connector reaches a designated position, and the limiting claw near the rear of the support base rises. At this time, the first rebar and the connector continue to move. After the connector triggers the proximity switch of the rear limiting claw, the connector and the first rebar stop moving. The second rebar moves from the front to the rear of the support base along the first direction to a designated position, and the limiting claw near the front of the support base rises. The rotating component clamps the connector and then rotates it, causing the connector to screw into the end of the second rebar and simultaneously move towards the second rebar. When the connector triggers the proximity switch of the front limiting claw, the rotating component stops rotating. The rebar splicing device can limit the position of the connector, and the rotating component automatically stops after the connector is connected to the second rebar, ensuring accurate connection. The clamping component automatically clamps the first and second rebars, saving manpower and resources.

[0033] The rebar splicing operation method provided by this invention is applied to a rebar splicing operation device. When the first rebar moves from the front to the rear of the support along a first direction, the connector reaches a designated position, and the limiting claw near the rear of the support rises. At this time, the first rebar and the connector continue to move. After the connector triggers the proximity switch of the rear limiting claw, the connector and the first rebar stop moving. The second rebar moves from the front to the rear of the support along the first direction to a designated position, and the limiting claw near the front of the support rises. The rotating component clamps the connector and rotates it. The connector screws into the end of the second rebar and moves toward the second rebar at the same time. When the connector triggers the proximity switch of the front limiting claw, the rotating component stops rotating, so that the first and second rebars are automatically connected and the connection position is accurate, improving work efficiency and saving manpower and resources.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] like Figures 2-7As shown, this embodiment of the invention provides a rebar splicing device, including a support base 1, a limiting component 3, a rotating component 4, and two clamping components 2. The support base 1 has conveying mechanisms on both sides along a first direction (i.e., the X direction). These conveying mechanisms can transport the first rebar 100 and the second rebar 200 to be spliced ​​onto the support base 1 and can also output them. It should be noted that when the first rebar 100 or the second rebar 200 is located in front of the support base 1, it is conveyed by the conveying mechanism located in front of the support base 1. After the first rebar 100 or the second rebar 200 passes through the support base 1, it is conveyed by the conveying mechanism located behind the support base 1. A connector 300 is provided at the rear end of the first rebar 100, and the connector 300 uses a threaded connection to splice the first rebar 100 and the second rebar 200. The connector 300 is connected to the first reinforcing bar 100 and the second reinforcing bar 200. The limiting component 3 includes two limiting claws 31, which are spaced apart on the support base 1 along the first direction and can be raised and lowered in the vertical direction. A proximity switch is provided on the opposite side of the two limiting claws 31, and the connector 300 can be limited between the two limiting claws 31. Two clamping components 2 are spaced apart at both ends of the support base 1 along the first direction. The two clamping components 2 can clamp the first reinforcing bar 100 and the second reinforcing bar 200 respectively, so that the first reinforcing bar 100 and the second reinforcing bar 200 are fixed when the connector 300 rotates. The rotating component 4 is disposed between the two limiting claws 31 for rotating. The adapter 300 enables the adapter 300 to be threadedly connected to the second reinforcing bar 200. The connection process is as follows: when the first reinforcing bar 100 moves from the front side to the rear side of the support base 1 along the first direction to a set position, the limiting claw 31 near the rear side of the support base 1 rises, and the first reinforcing bar 100 continues to move within the U-shaped groove of the U-shaped block 312 of the limiting claw 31. After the adapter 300 triggers the proximity switch of the limiting claw 31 on the rear side, it stops moving, and the clamping assembly 2 near the rear side of the support base 1 clamps the first reinforcing bar 100. The second reinforcing bar 200 moves from the front side to the rear side of the support base 1 along the first direction to a set position, and the limiting claw 31 near the front side of the support base 1 rises. The clamping assembly 2, located near the rear of the support base 1, clamps the second reinforcing bar 200. At this time, the connector 300 is located between the two limiting claws 31. The rotating assembly 4 rotates the connector 300 to make the connector 300 threadedly connected to the second reinforcing bar 200. When the connector 300 is threadedly connected to the second reinforcing bar 200, it moves towards the second reinforcing bar 200. When the connector 300 triggers the proximity switch of the limiting claw 31 on the rear side, the rotating assembly 4 stops rotating, indicating that the connector 300 is connected. The two clamping assemblies 2 release the first reinforcing bar 100 and the second reinforcing bar 200, and the conveying mechanism continues to convey the connected first reinforcing bar 100 and the second reinforcing bar 200.

[0059] The rebar splicing device can limit the position of the connector 300, and the rotating component 4 automatically stops after the connector 300 is connected to the second rebar 200, ensuring accurate connection. The clamping component 2 automatically clamps the first rebar 100 and the second rebar 200, saving manpower and resources.

[0060] The rebar splicing device also includes a grating sensor 5, which is located in the area between the clamping assembly 2 and the limiting claw 31 on the front side of the support base 1. When the first rebar 100 is conveyed, the front end of the first rebar 100 first triggers the rising edge signal of the grating sensor 5, causing the grating sensor 5 to count to 1, and the first rebar 100 is conveyed. When the rear end, which is equipped with the connector 300, triggers the falling edge signal of the grating sensor 5 through the grating sensor 5, causing the grating sensor 5 to count to 2, the limiting claw 31 located on the rear side rises, and the first rebar 100 is conveyed until the connector 300 triggers the proximity switch of the limiting claw 31 on the rear side, at which point the conveying stops; the second rebar 200 is then conveyed, and the second rebar 200... The rising edge signal of the front end triggers the grating sensor 5, causing the grating sensor 5 to count to 3. At this time, the second reinforcing bar 200 stops conveying after a set time, that is, the front end of the second reinforcing bar 200 reaches the set position. The rotating component 4 rotates the connector 300 until the connector 300 triggers the proximity switch of the limit claw 31 near the front side of the support base 1, and then stops rotating. The conveying device outputs the connected first reinforcing bar 100 and second reinforcing bar 200 simultaneously. The rear end of the second reinforcing bar 200 triggers the falling edge signal of the grating sensor 5, at which time the grating sensor 5 counts to 4. The grating sensor 5 realizes the position detection of the first reinforcing bar 100, the connector 300 and the second reinforcing bar 200, as well as the counting of the first reinforcing bar 100 and the second reinforcing bar 200. When the count of the grating sensor 5 reaches the set value, a stop signal can be issued.

[0061] It should be explained that when the rebar splicing device is started and initialized, the PLC terminal grating sensor 5 counts to 0. The total length 'a' of the finished rebar to be processed and the length 'b' of a single first rebar 100 or second rebar 200 (the lengths of the first rebar 100 and the second rebar 200 are equal) are manually input. The maximum count value y of grating sensor 5 is 2*(floor(a / b)+1). All of the above data are stored in the PLC. When grating sensor 5 reaches the maximum count value, a stop signal is issued.

[0062] The rotating assembly 4 includes a main support 41 and a slave support 42. A drive wheel 43 is mounted on the main support 41 via a drive shaft. A driven wheel 44 is mounted on the slave support 42 via a driven shaft. When the connector 300 is positioned between the two limiting claws 31, the connector 300 is supported on the driven wheel 44. The main support 41 and the slave support 42 can approach each other to clamp the connector 300. The drive wheel 43 is connected to a drive motor via a transmission component. The drive motor can drive the drive wheel 43 to rotate, thereby causing the connector 300 to rotate. The transmission component can be a chain drive, belt drive, or gear drive, etc.

[0063] Preferably, the monitoring of whether the connector 300 has been successfully screwed into the second reinforcing bar 200 can be achieved by monitoring the real-time torque of the drive motor. If the torque is too large, an alarm will be triggered and the machine will be stopped to prompt adjustment of the reinforcing bar splicing device.

[0064] To ensure greater stability of the connector 300 when clamped between the driving wheel 43 and the driven wheel 44, two driven wheels 44 are provided. Two sets of support frames are spaced apart along the second direction (Y direction) from the bracket 42, with two driven shafts respectively mounted on the two support frames, and the two driven wheels 44 respectively mounted on the two driven shafts. When the connector 300 is confined between the two limiting claws 31, the connector 300 is supported on the two driven wheels 44.

[0065] Furthermore, the rotating assembly 4 also includes a horizontal cylinder and a first vertical cylinder. The main support 41 is slidably mounted on the support base 1 along the second direction, and the main support 41 is connected to the output end of the horizontal cylinder. The horizontal cylinder can drive the main support 41 to move toward or away from the secondary support 42. The secondary support 42 is connected to the output end of the first vertical cylinder, and the first vertical cylinder can drive the secondary support 42 to move up and down along the vertical direction (i.e., the Z direction). This structure is simple and easy to use.

[0066] The limiting component 3 also includes a second vertical cylinder. The limiting claw 31 is located at the output end of the second vertical cylinder. The second vertical cylinder can realize the lifting and lowering of the limiting claw 31. The structure is relatively simple and easy to use.

[0067] Furthermore, the limiting assembly 3 also includes two limiting blocks 32. Each limiting block 32 has a groove on the side facing the limiting claw 31. The bottom end of the vertical rod 311 of the limiting claw 31 is connected to the output end of the second vertical cylinder, and the vertical rod 311 is slidably positioned within the groove. This structure makes the limiting claw 31 more robust and its overall structure more rational.

[0068] Continue to refer to Figure 2 and Figure 6The clamping assembly 2 includes a driving member and two clamping plates 21. The two clamping plates 21 are spaced apart along a second direction. The driving member can drive the two clamping plates 21 to move closer or further apart from each other to clamp or release the first reinforcing bar 100 or the second reinforcing bar 200.

[0069] Specifically, the driving component is a driving cylinder 22, and the clamping assembly 2 also includes a fixed gear 23 and two racks 24. The racks 24 are slidably mounted on the support base 1 via guide blocks 25. The fixed gear 23 is rotatably mounted on the support base 1. The two racks 24 are respectively located on both sides of the fixed gear 23 and mesh with it. The two racks 24 are respectively fixedly connected to two clamping plates 21. The output end of the driving cylinder 22 is fixedly connected to one clamping plate 21. In this structure, the driving cylinder 22 pushes one clamping plate 21 to move, causing the racks 24 mounted on the clamping plate 21 to move, which in turn drives the fixed gear 23 to rotate. While the fixed gear 23 rotates, it drives the other rack 24 to move in the opposite direction, which in turn drives the other clamping plate 21 to move in the opposite direction, so as to make the two clamping plates 21 move closer or further apart.

[0070] Furthermore, the clamping assembly 2 also includes two support plates 26, which are spaced apart on the support base 1 along a second direction. Two guide shafts 27 are spaced apart between the two support plates 26 along a first direction. The clamping plate 21 is mounted on the guide shafts 27 via sliding bearings 28. This structure allows the clamping plate 21 to slide more smoothly and is more structurally sound.

[0071] In other embodiments, the clamping assembly 2 may also be implemented using a parallel-moving finger cylinder.

[0072] Reference Figure 7 Clamping blocks 211 are provided on the opposing sides of the two clamping plates 21, and V-shaped grooves are provided on the opposing sides of the two clamping blocks 211. The first steel bar 100 and the second steel bar 200 are clamped in the two V-shaped grooves to make the clamping more secure.

[0073] This invention also provides a method for splicing reinforcing bars, using the aforementioned reinforcing bar splicing device, with reference to... Figures 8-11 The method for splicing rebar includes the following steps:

[0074] When the equipment is powered on and initialized, the limit chuck 31, clamping plate 21, drive wheel 43 and driven wheel 44 all return to their original positions. The number of steel bars to be processed is manually input and saved in the PLC.

[0075] When the equipment is started, the rear end of the first reinforcing bar 100 is threaded using an upsetting and threading device (which flattens the end of the reinforcing bar to thicken it). The threading diameter is greater than or equal to the original diameter of the first reinforcing bar 100 (to improve the connection strength), and the threading length of the first reinforcing bar 100 is equal to the length of the connector 300 (so that the connector 300 can be fully inserted into the rear end of the first reinforcing bar 100 when initially connected to it). The front end of the second reinforcing bar 200 is threaded using the upsetting and threading device, and the threading length is equal to half the length of the connector 300.

[0076] The conveying equipment conveys the first reinforcing bar 100 from the front to the rear of the support base 1 along the first direction. The front end of the first reinforcing bar 100 triggers the rising edge signal of the grating sensor 5 and continues to convey until the rear end of the first reinforcing bar 100 triggers the falling edge signal of the grating sensor 5 (i.e., the connector 300 triggers the falling edge signal of the grating sensor 5), and the limiting claw 31 near the rear of the support base 1 rises. At this time, the first reinforcing bar 100 continues to convey, and the connector 300 stops conveying after triggering the proximity switch of the limiting claw 31 on the rear side.

[0077] The first reinforcing bar 100 moves into place, and the two clamping plates 21 of the clamping assembly 2 near the rear side of the support base 1 move closer to each other so that the first reinforcing bar 100 is clamped in the two V-shaped grooves;

[0078] The conveying device continues to convey the second steel bar 200. The second steel bar 200 moves from the front side to the rear side of the support 1 along the first direction. After the front end of the second steel bar 200 triggers the rising edge signal of the grating sensor 5, it continues to move for a set time and then stops. At this time, the front end of the second steel bar 200 reaches the set position.

[0079] The second reinforcing bar 200 moves into place, and the two clamping plates 21 of the clamping assembly 2 near the front side of the support base 1 move closer to each other so that the second reinforcing bar 200 is clamped in the two V-shaped grooves;

[0080] Driven by the horizontal cylinder, the main support 41 drives the driving wheel 43 to move toward the driven wheel 44 in the second direction. The first vertical cylinder drives the driven wheel 44 to move upward in the vertical direction. The driving wheel 43 and the driven wheel 44 clamp the connector 300. The drive motor is started to drive the driving wheel 43 to rotate, so that the connector 300 rotates. When the connector 300 rotates, it rotates out of the first steel bar 100. At the same time as the connector 300 rotates out of the first steel bar 100, it rotates to connect to the second steel bar 200 and moves toward the second steel bar 200. When the connector 300 triggers the proximity switch of the limit claw 31 on the front side, the drive motor stops. At this time, the connector 300 has not completely withdrawn from the first steel bar 100, thus completing the connection of the first steel bar 100 and the second steel bar 200 and outputting.

[0081] Repeat the above operation process to continue connecting the third and fourth reinforcing bars, the fifth and sixth reinforcing bars, and so on, until the maximum set value recorded by the PLC is reached and then the machine stops.

[0082] This rebar splicing operation method is applied to a rebar splicing operation device. By moving the first rebar 100 from the front to the rear of the support base 1 along a first direction to a set position, the limiting claw 31 near the rear of the support base 1 rises. The first rebar 100 continues to move within the U-shaped groove of the U-shaped block 312 of the limiting claw 31. The connector 300 stops moving after triggering the proximity switch of the limiting claw 31 on the rear side, and the clamping assembly 2 near the rear of the support base 1 clamps the first rebar 100. The second rebar 200 moves from the front to the rear of the support base 1 along the first direction to a set position. The limiting claw 31 near the front of the support base 1 rises, and the clamping assembly 2 near the rear of the support base 1 clamps the second rebar 200. At this time, the connection... The connector 300 is located between two limiting claws 31. The rotating assembly 4 rotates the connector 300 to make the connector 300 threadedly connected to the second reinforcing bar 200. When the connector 300 is threadedly connected to the second reinforcing bar 200, it moves towards the second reinforcing bar 200. When the connector 300 triggers the proximity switch of the limiting claw 31 on the rear side, the rotating assembly 4 stops rotating, indicating that the connector 300 is connected. The two clamping assemblies 2 release the first reinforcing bar 100 and the second reinforcing bar 200. The conveying mechanism continues to convey the connected first reinforcing bar 100 and the second reinforcing bar 200 so that the first reinforcing bar 100 and the second reinforcing bar 200 are automatically connected and the connection position is accurate, which improves work efficiency and saves manpower and material resources.
