And the automatic dismounting spool can automatically finish dismounting the reinforcing steel bar roll after the reinforcing steel bar roll is formed by coiling, thereby reducing the labor intensity of workers and improving the safety of the working environment of the workers.

As shown in fig. 1 to 5, the automatic detaching spool includes a spool main body, a sector frame retracting mechanism 4, a head clamping mechanism 6, and a tail clamping mechanism 5. The spool body is integrally I-shaped and comprises a top cover 1, a revolving body 2 and a base 3. The top cover 1 is an annular structure formed by splicing plates, a plurality of reinforcing rib plates can be arranged on the top cover according to requirements, and in the embodiment, the top cover 1 is annular. The base 3 is the platform column structure that adopts the plate concatenation to form, also can set up a plurality of reinforcing floor on it according to the demand, and in this embodiment, the base 3 is round platform form, is provided with the installation cavity of undercut on the top surface of base 3. Top cap 1 and base 3 parallel arrangement, base 3 are located top cap 1's below, and the solid of revolution 2 sets up between top cap 1 and base 3, and the diameter of the solid of revolution 2 is less than top cap 1, base 3's diameter, forms the accommodation space of coiling reinforcing bar between top cap 1's bottom surface, the outer wall of the solid of revolution 2 and the top surface of base 3. When the automatic dismounting spool rotates under the action of external force, the steel bar can be wound on the revolving body 2 and is contained in the containing space.

In this embodiment, as shown in fig. 1, the rotator 2 includes a plurality of fan-shaped frames 21, the plurality of fan-shaped frames 21 are arranged around the central axis of the whole automatic dismounting spool to form an annular structure, and the middle cavity on the top cover 1, the middle cavity of the rotator 2 and the installation cavity on the base 3 form accommodating through holes.

In this embodiment, the installation cavity is a circular cavity, the outer wall surfaces of the fan-shaped frames 21 are surrounded to form a cylindrical surface, and the bottom ends of the cylindrical surfaces can be inserted into the installation cavity, so that the detachable connection between the revolving body 2 and the base 3 is realized.

The number of the fan-shaped brackets 21 is set as required, and in the present embodiment, four fan-shaped brackets 21 are provided. Each fan frame 21 has the same structure, and as shown in fig. 6, each fan frame 21 includes an arc plate 211 and two mounting plates 212, and the two mounting plates 212 are disposed in parallel on the inner side of the arc plate 211 and along the length direction of the arc plate 211. The tops of the two mounting plates 212 are respectively provided with a rotating shaft hole, the top cover 1 is also provided with a rotating shaft hole, and the rotating shafts sequentially penetrate through the three rotating shaft holes, so that the rotating connection between the fan-shaped frame 21 and the top cover 1 is realized.

In order to enable the steel bar roll to be automatically disassembled from the automatic disassembling spool after the steel bar roll is formed by winding, the automatic disassembling spool further comprises a sector frame retracting mechanism 4, and the sector frame retracting mechanism 4 is arranged inside the spool main body and is positioned in the accommodating through hole. The lower part of the fan-shaped frame 21 can retract towards the direction close to the central axis of the rotator 2 under the action of the first external force so as to reduce the size of the lower part of the rotator 2, so that the rotator 2 can be separated from the mounting cavity of the base 3, and the steel bar coil can be detached from the lower part of the rotator 2 by continuously retracting the lower part of the fan-shaped frame 21 towards the direction close to the central axis of the rotator 2.

Specifically, as shown in fig. 3, the sector frame retracting mechanism 4 includes a first inner cylinder 41, a center shaft 42, a convex sliding table 43, and a plurality of pulleys 44. The first inner cylinder 41 is disposed in the accommodating through hole and fixedly connected to the top cover 1, and the first inner cylinder 41 is provided with a bundling guide slot 22 for facilitating bundling of the steel bar roll. The central shaft 42 is disposed in the first inner cylinder 41, the convex sliding table 43 is connected to the bottom end of the central shaft 42, and the top end of the central shaft 42 is disposed near the top surface of the first inner cylinder 41, so that the external driving mechanism can apply a first external force to the top end of the central shaft 42. Driven by the first external force, the central shaft 42 moves downward integrally along the axial direction of the first inner cylinder 41 and drives the convex sliding table 43 to move downward.

The outer wall surface of the convex sliding table 43 is a special-shaped surface having a plurality of 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 a lower portion of the fan frame 21, and specifically, a rotating shaft hole is provided at each of lower portions of two mounting plates 212 of the fan frame 21, the pulley 44 is disposed between the two mounting plates 212 and is disposed to protrude from the mounting plates 212, and a rotating shaft passes through the lower portions of the mounting plates 212 and the pulley 44, thereby rotatably connecting the pulley 44 to the lower portion of the fan frame 21. In this embodiment, a pulley 44 is rotatably connected to each fan frame 21. Of course, in other embodiments, two or more pulleys 44 may be rotatably connected to the segment frame 21 as desired.

Each pulley 44 abuts against a special-shaped surface on the convex sliding table 43, when the automatic dismounting spool is in an initial state, namely the central shaft 42 is not subjected to the first external force, the pulley 44 abuts against the lower part of the convex sliding table 43, and the width of the lower part of the convex sliding table 43 is larger, so that the diameter of the lower part of the revolving body 2 formed by the four fan-shaped frames 21 is larger, and the revolving body can be stably clamped in the installation cavity. When the central shaft 42 is subjected to a first external force, the convex sliding table 43 moves downwards under the driving of the central shaft 42, so that the pulley 44 rolls from bottom to top on the special-shaped surface of the convex sliding table 43, the width of the special-shaped surface where the pulley 44 is located is reduced, the lower part of the sector frame 21 gradually approaches the central shaft 42, the whole size of the lower part of the revolving body 2 is small, and a gap is formed between the lower part of the revolving body and the installation cavity. At this time, if the top cover 1 and the rotator 2 receive an upward external force, the rotator 2 can be smoothly separated from the base 3.

Further, the removal of the rebar roll from the automatic removal spool requires three steps: firstly, separating the revolving body 2 from the base 3; secondly, transferring the revolving body 2 carrying the steel bar coil to a steel bar coil unloading station; and thirdly, separating the reinforcing steel bar coil from the revolving body 2. Therefore, in the whole process, the rotator 2 needs to be retracted twice, and the first external force also includes two stages, namely a first force application stage and a second force application stage. In the first force application stage, the revolving body 2 retracts for the first time to provide a space for separating the revolving body 2 from the base 3; in the second force application stage, the revolving body 2 retracts for the second time, and a space is provided for separating the reinforcing steel bar coil from the revolving body 2. Therefore, in the present embodiment, the irregular surface on the convex sliding table 43 has three widths from top to bottom, which are respectively a first width, a second width and a third width that are increased in sequence. When the top of the central shaft 42 is not stressed, the pulley 44 abuts at the third width of the profiled surface; after the first force application stage, the pulley 44 abuts against the second width of the special-shaped surface; after the second force application phase, the pulley 44 abuts at the first width of the profiled surface.

Specifically, specific values of the first width, the second width, and the third width are not limited, and are set as required. In order to improve the stability of the rotation of the pulley 44, the different widths of the convex sliding table 43 are smoothly transited. Of course, in other embodiments, the first width, the second width and the third width may be three intervals, and the difference between the widths of the intervals is small, so as to ensure that the above-mentioned gradual retraction function can be realized and the stability of the rolling of the pulley 44 can be improved.

Further, in order to improve the stability of the whole automatic dismounting spool structure, as shown in fig. 3, the bottom of the fan-shaped frame 21 is provided with a limiting hook 45, the limiting hook 45 is provided with an L-shaped limiting surface, a limiting block 31 is arranged in the installation cavity, the limiting block 31 is horizontally arranged, and the L-shaped limiting surface of the limiting hook 45 can be clamped at the bottom surface of the limiting block 31 and the L-shaped surface formed by the side surface. In the initial state of automatically detaching the spool, that is, when the top of the central shaft 42 is not stressed, the limiting hook 45 has a first state of hooking the limiting block 31, so that the connection strength of the revolving body 2 and the base 3 in the initial state is improved, and accidental detachment is avoided. And after above-mentioned first application of force stage, because the lower part of solid of revolution 2 is retracted, spacing hook 45 has and breaks away from stopper 31 and colludes the second state of linking in the reinforcing bar book bottom, and at this moment, spacing hook 45 can carry out spacingly to the reinforcing bar book, avoids the reinforcing bar book just to take place to break away from with solid of revolution 2 before reaching reinforcing bar uninstallation station to the emergence of incident has been avoided. After the second force application stage, the lower portion of the rotator 2 continues to retract, so that the stopper hook 45 has a third state of being disengaged from the bead roll.

Further, as shown in fig. 3, the automatic dismounting spool further includes a retraction power mechanism, and the retraction power mechanism is configured to provide additional power for retraction of the fan-shaped frame 21, so as to avoid that the fan-shaped frame 21 is connected with the top cover 1 only by rotation and the fan-shaped frame 21 cannot be retracted smoothly. In this embodiment, the retracting power mechanism includes a plurality of tension springs 46, one tension spring 46 is disposed between each fan frame 21 and the first inner cylinder 41, one end of each tension spring 46 is connected to the fan frame 21, the other end is connected to the first inner cylinder 41, and the initial state of each tension spring 46 is a stretching state. Under the pulling force of the tension spring 46, the fan-shaped frame 21 can be pulled and retracted as long as the width of the abutting part of the pulley 44 and the convex sliding table 43 is changed. Of course, in other embodiments, a plurality of tension springs 46 can be disposed between each fan frame 21 and the first inner cylinder 41 to increase the tension.

Further, in order to automatically reset the sector frame retraction mechanism 4 after the first external force is removed so as to reassemble the revolving body 2 with the base 3, the automatic disassembling spool further comprises a first reset mechanism. As shown in fig. 3, the first return mechanism includes a first spring 47 and a gland 48, the first spring 47 is sleeved between the central shaft 42 and the first inner cylinder 41, the gland 48 is fixed on the top cover 1 and pressed against the top of the first spring 47, and the bottom of the first spring 47 is fixed in the first inner cylinder 41. When the center shaft 42 moves downward by 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, the central shaft 42 automatically moves upward under the action of the restoring force to drive the convex sliding table 43 to move upward and reset the lower part of the revolving body 2.

Optionally, to enable the installation of the first spring 47, the first return mechanism further comprises an upper stop 49 and a lower stop 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 end of the first spring 47 is fixedly connected with the bottom surface of the upper baffle 49, and the top surface of the upper baffle 49 abuts against the bottom surface of the gland 48.

The tail clamping mechanism 5 is used for fixing the tail of the reinforcing steel bar roll when the reinforcing steel bar roll is wound, so that the phenomena that the reinforcing steel bar is partially scattered and the tail is not searched well due to inaccurate fixation of the tail of the reinforcing steel bar roll are avoided.
