Description

The steel bar take-up machine is a kind of equipment that can automatically finish, coil and transport steel bars. The I-shaped wheel is an important part of the steel bar take-up machine. It can fix the head of the steel bar and wrap the steel bar around it by rotation. After the steel bar is coiled, the tail of the steel bar is fixed to form a steel bar coil. The formed steel bar coil needs to be removed from the I-shaped wheel. When the steel bar coil reaches the place of use, the steel bar coil needs to be paid out for the second time to reach the use state. Therefore, the coiling quality of the steel bar coil directly determines the difficulty of the second time pay-out and the quality of the use state.

[0003] In the prior art, manual assistance is generally required to complete the fixing of the ends of the steel bars, which not only has a low degree of automation but also has high labor intensity. Alternatively, the main machine is used to automatically fix the steel bars, but this method has the disadvantages of arbitrary fixing positions, poor hiding of the ends of the steel bars, easy tangling of the wires when the steel bars are wound, uneven wiring, and low aesthetics, which seriously affects the appearance quality of the steel bar coil and the stability of the secondary wire laying.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] The present embodiment provides an automatic disassembly I-shaped wheel, which can be used in a steel bar take-up machine to automatically fix the head of the steel bar before the steel bar is coiled and automatically fix the tail of the steel bar after the steel bar is coiled, thereby improving the aesthetics of the coiled steel bar and avoiding the occurrence of tangled wires. The automatic disassembly I-shaped wheel can also automatically disassemble the steel bar coil after the steel bar coil is coiled, thereby reducing the labor intensity of workers and improving the safety of the workers' working environment.

[0054] like Figures 1 to 5 As shown, the automatic disassembly of the I-shaped wheel includes an I-shaped wheel body, a fan-shaped frame retracting mechanism 4, a head clamping mechanism 6 and a tail clamping mechanism 5. Among them, the I-shaped wheel body is in the shape of an "I" as a whole, and includes a top cover 1, a rotating body 2 and a base 3. The top cover 1 is an annular structure formed by splicing plates, and a plurality of reinforcing ribs can be arranged on it according to requirements. In this embodiment, the top cover 1 is an annular shape. The base 3 is a table-shaped structure formed by splicing plates, and a plurality of reinforcing ribs can also be arranged on it according to requirements. In this embodiment, the base 3 is a truncated table shape, and a downwardly recessed installation cavity is arranged on the top surface of the base 3. The top cover 1 and the base 3 are arranged in parallel, and the base 3 is located below the top cover 1. The rotating body 2 is arranged between the top cover 1 and the base 3. The diameter of the rotating body 2 is smaller than the diameters of the top cover 1 and the base 3. The bottom surface of the top cover 1, the outer wall surface of the rotating body 2 and the top surface of the base 3 form a accommodating space for winding steel bars. When the automatic disassembly spool rotates under the action of external force, the steel bars can be wound around the rotating body 2 and accommodated in the accommodating space.

[0055] In this embodiment, if Figure 1 As shown, the rotating body 2 includes a plurality of fan-shaped frames 21, which are arranged in a ring structure around the central axis of the entire automatic disassembly spool, and the middle cavity on the top cover 1, the middle cavity of the rotating body 2, and the installation cavity on the base 3 form an accommodating through hole. The top end of each fan-shaped frame 21 is rotatably connected to the top cover 1, and the bottom end of each fan-shaped frame 21 is inserted into the installation cavity. In this embodiment, the installation cavity is a circular cavity, and the outer wall surfaces of the plurality of fan-shaped frames 21 are arranged to form a cylindrical surface, and the bottom ends thereof can be inserted into the installation cavity, thereby realizing a detachable connection between the rotating body 2 and the base 3.

[0056] The number of the fan-shaped racks 21 is set according to the requirements. In this embodiment, four fan-shaped racks 21 are provided. The structure of each fan-shaped rack 21 is the same. Figure 6 As shown, the fan-shaped frame 21 includes an arc-shaped plate 211 and two mounting plates 212. The two mounting plates 212 are arranged in parallel on the inner side of the arc-shaped plate 211 and along the length direction of the arc-shaped plate 211. A rotating shaft hole is respectively arranged on the top of the two mounting plates 212, and a rotating shaft hole is also arranged on the top cover 1. The rotating shaft passes through the three rotating shaft holes in sequence, thereby realizing the rotation connection between the fan-shaped frame 21 and the top cover 1.

[0057] In order to automatically remove the steel bar coil from the automatic disassembly spool after the steel bar coil is wound, the automatic disassembly spool further includes a fan-shaped frame retracting mechanism 4, which is arranged inside the spool body and located in the accommodating through hole. Under the action of the first external force, the lower part of the fan-shaped frame 21 can be retracted toward the direction close to the central axis of the rotating body 2 to reduce the size of the lower part of the rotating body 2, so that the rotating body 2 can be separated from the installation cavity of the base 3, and the lower part of the fan-shaped frame 21 continues to retract toward the direction close to the central axis of the rotating body 2, so that the steel bar coil can be detached from the lower part of the rotating body 2.

[0058] Specifically, Figure 3 As shown, the fan-shaped frame retraction mechanism 4 includes a first inner cylinder 41, a central axis 42, a convex slide 43 and a plurality of pulleys 44. The first inner cylinder 41 is placed in the accommodating through hole and fixedly connected to the top cover 1. The first inner cylinder 41 is provided with a bundling guide groove 22 for facilitating the bundling of the steel bar coil. The central axis 42 is placed in the first inner cylinder 41, the convex slide 43 is connected to the bottom end of the central axis 42, and the top end of the central axis 42 is arranged close to the top surface of the first inner cylinder 41 to facilitate the external driving mechanism to apply a first external force to the top end of the central axis 42. Driven by the first external force, the central axis 42 moves downward as a whole along the axial direction of the first inner cylinder 41 and drives the convex slide 43 to move downward.

[0059] The outer wall surface of the convex sliding platform 43 is a profiled surface, which has multiple widths from top to bottom, and the width at the upper part is smaller than the width at the lower part. The pulley 44 is rotatably connected to the lower part of the fan-shaped frame 21. Specifically, a rotating shaft hole is respectively provided at the lower part of the two mounting plates 212 of the fan-shaped frame 21. The pulley 44 is arranged between the two mounting plates 212 and protrudes from the mounting plates 212. The rotating shaft passes through the lower part of the mounting plates 212 and the pulley 44, so that the pulley 44 is rotatably connected to the lower part of the fan-shaped frame 21. In the present embodiment, each fan-shaped frame 21 is rotatably connected to a pulley 44. Of course, in other embodiments, two or more pulleys 44 can also be rotatably connected to the fan-shaped frame 21 according to requirements.

[0060] Each pulley 44 abuts against the profiled surface on the convex slide 43. When the automatic disassembly I-shaped wheel is in the initial state, that is, before the central axis 42 is subjected to the first external force, the pulley 44 abuts against the lower part of the convex slide 43. Since the width of the lower part of the convex slide 43 is large, the diameter of the lower part of the rotating body 2 formed by the four fan-shaped frames 21 is large, and it can be stably clamped in the installation cavity. When the central axis 42 is subjected to the first external force, since the convex slide 43 moves downward under the drive of the central axis 42, the pulley 44 rolls from bottom to top on the profiled surface of the convex slide 43, the width of the profiled surface where the pulley 44 is located decreases, the lower part of the fan-shaped frame 21 gradually approaches the central axis 42, the overall size of the lower part of the rotating body 2 is small, and a gap appears between the installation cavity. At this time, if the top cover 1 and the rotating body 2 are subjected to an upward external force, the rotating body 2 can be smoothly separated from the base 3.

[0061] Furthermore, since it takes three steps to remove the steel coil from the automatic disassembly I-wheel: 1. Separate the rotating body 2 from the base 3; 2. Transfer the rotating body 2 carrying the steel coil to the steel coil unloading station; 3. Separate the steel coil from the rotating body 2. Therefore, during the whole process, the rotating body 2 needs to retract twice, and the first external force also includes two stages: the first force application stage and the second force application stage. In the first force application stage, the rotating body 2 retracts for the first time to provide space for the separation of the rotating body 2 from the base 3; in the second force application stage, the rotating body 2 retracts for the second time to provide space for the separation of the steel coil from the rotating body 2. Therefore, in this embodiment, the special-shaped surface on the convex slide 43 has three widths from top to bottom, which are the first width, the second width and the third width that increase in sequence. When the top of the central axis 42 is not subjected to force, the pulley 44 abuts against the third width of the profiled surface; after the first force application stage, the pulley 44 abuts against the second width of the profiled surface; after the second force application stage, the pulley 44 abuts against the first width of the profiled surface.

[0062] Specifically, the specific values ​​of the first width, the second width, and the third width are not limited and are set according to requirements. In order to improve the stability of the rotation of the pulley 44, the convex slide 43 has a smooth transition between different widths. Of course, in other embodiments, the first width, the second width, and the third width can also be three interval values, and the width difference of each interval value is very small, so as to ensure that the above-mentioned gradual retraction function can be achieved and the rolling stability of the pulley 44 can be improved.

[0063] Furthermore, in order to improve the stability of the entire automatic disassembly spool structure, as Figure 3 As shown, a limit hook 45 is provided at the bottom of the fan-shaped frame 21, and an L-shaped limit surface is provided on the limit hook 45. A limit block 31 is provided in the installation cavity, and the limit block 31 is arranged horizontally. The L-shaped limit surface of the limit hook 45 can be clamped at the L-shaped surface formed by the bottom and side surfaces of the limit block 31. In the initial state of automatic disassembly of the I-shaped wheel, that is, when the top of the central axis 42 is not subjected to force, the limit hook 45 has a first state of being hooked on the limit block 31, thereby improving the connection strength of the rotating body 2 and the base 3 in the initial state, and avoiding accidental separation. And after the above-mentioned first force application stage, due to the retraction of the lower part of the rotating body 2, the limit hook 45 has a second state of being separated from the limit block 31 and hooked on the bottom of the steel bar coil. At this time, the limit hook 45 can limit the steel bar coil, and avoid the steel bar coil from being separated from the rotating body 2 before reaching the steel bar unloading position, thereby avoiding the occurrence of safety accidents. After the second force application stage, since the lower part of the rotating body 2 continues to retract, the limiting hook 45 has a third state of being separated from the steel bar coil.

[0064] Furthermore, if Figure 3 As shown, the automatic disassembly of the I-shaped wheel also includes a retraction power mechanism, which is used to provide additional power for the retraction of the fan-shaped frame 21, so as to avoid the fan-shaped frame 21 being unable to retract smoothly only by relying on the rotation connection between the fan-shaped frame 21 and the top cover 1 and the state of the fan-shaped frame 21. In this embodiment, the retraction power mechanism includes a plurality of tension springs 46, and a tension spring 46 is arranged between each fan-shaped frame 21 and the first inner cylinder 41, one end of the tension spring 46 is connected to the fan-shaped frame 21, and the other end is connected to the first inner cylinder 41, and the initial state of the tension spring 46 is a tension state. Under the tension of the tension spring 46, as long as the width of the abutment between the pulley 44 and the convex slide 43 changes, the fan-shaped frame 21 can be pulled and retracted. Of course, in other embodiments, a plurality of tension springs 46 can also be arranged between each fan-shaped frame 21 and the first inner cylinder 41 to increase the tension.

[0065] Furthermore, in order to enable the fan-shaped frame retracting mechanism 4 to automatically reset after the first external force is removed so as to reassemble the rotating body 2 with the base 3, the automatic disassembly spool also includes a first reset mechanism. Figure 3As shown, the first reset mechanism includes a first spring 47 and a pressure cover 48. The first spring 47 is sleeved between the central shaft 42 and the first inner cylinder 41. The pressure cover 48 is fixed on the top cover 1 and presses against the top of the first spring 47. The bottom of the first spring 47 is fixed in the first inner cylinder 41. When the central shaft 42 moves downward under the action of the first external force, the top of the first spring 47 moves downward and is compressed to generate a restoring force; when the first external force is removed, under the action of the restoring force, the central shaft 42 automatically moves upward to drive the convex slide 43 to move upward and reset the lower part of the rotating body 2.

[0066] Optionally, in order to realize the installation of the first spring 47, the first reset mechanism further includes an upper baffle 49 and a lower baffle 410. The upper baffle 49 and the lower baffle 410 are both annular baffles, the upper baffle 49 is sleeved and fixed on the top of the central shaft 42, the top of the first spring 47 is fixedly connected to the bottom surface of the upper baffle 49, and the top surface of the upper baffle 49 abuts against the bottom surface of the pressure cover 48. A step surface is set on the inner wall surface of the first inner cylinder 41, the lower baffle 410 is sleeved on the middle part of the central shaft 42, and there is a gap between the lower baffle 410 and the central shaft 42, the lower baffle 410 is placed on the step surface, and is fixedly connected to the bottom of the first spring 47. Under the action of the first external force, the central shaft 42 moves downward, and drives the upper baffle 49 to move downward. Since the position of the lower baffle 410 remains unchanged, the purpose of compressing the first spring 47 can be achieved.

[0067] The tail clamping mechanism 5 is used to fix the tail of the steel bar coil when the steel bar coil is wound, so as to avoid the steel bar being scattered and the tail being difficult to find due to inaccurate fixing of the tail of the steel bar coil. Figure 4 As shown, the tail clamping mechanism 5 includes a rotating connecting rod and a tail clip 51, the tail clip 51 is arranged at one end of the rotating connecting rod, and the rotating connecting rod is configured to be able to rotate under the action of the second external force to drive the tail clip 51 to open. Optionally, the rotating connecting rod includes a first connecting rod 52, a second connecting rod 53 and a third connecting rod 54, the first connecting rod 52 and the third connecting rod 54 are arranged in parallel, one end of the first connecting rod 52 is rotatably connected to the base 3, a force application point is arranged in the middle of the first connecting rod 52, and the second external force is applied to the force application point, the other end of the first connecting rod 52 is rotatably connected to one end of the second connecting rod 53, the other end of the second connecting rod 53 is rotatably connected to the middle of the third connecting rod 54, one end of the third connecting rod 54 is rotatably connected to the base 3, and the other end is connected to the tail clip 51.

[0068] Furthermore, the tail clamping mechanism 5 also includes a second reset mechanism, which is configured to drive the rotating connecting rod to reset when the second external force is cancelled, so that the tail clamp 51 clamps the tail of the steel bar roll. Specifically, the second reset mechanism is a compression spring 55, one end of the compression spring 55 is connected to the first connecting rod 52, and the other end is connected to the second connecting rod 53. The compression spring 55 is in a compressed state when the tail clamp 51 is opened, so that after the second external force is cancelled, the first connecting rod 52 can be reset under the action of the compression spring 55, thereby driving the second connecting rod 53, the third connecting rod 54 and the tail clamp 51 to reset, thereby achieving the purpose of clamping the tail of the steel bar roll.

[0069] The head clamping mechanism 6 is used to clamp the head of the steel bar. Figures 7 to 10 As shown, the head clamping mechanism 6 includes a support seat 61, a clamping arm 62, a driving arm 63, a driving plate 64 and a third reset mechanism 65. There are two clamping arms 62, the middle of which is rotatably connected to the support seat 61, one end of which is a clamping end and the other end is a driving end. There are two driving arms 63, which are arranged one by one corresponding to the two clamping arms 62. One end of the driving arm 63 is rotatably connected to the driving end and the other end is rotatably connected to the driving plate 64. When the driving plate 64 moves toward the clamping arm 62, the two driving ends can be spread apart by the driving arm 63, so that the two clamping ends are close to each other to clamp the steel bars. The third reset mechanism 65 is arranged on the support seat 61, so that the two clamping ends are in an open state spaced apart from each other in a free state.
