[0029] 2. Cutting device. Detailed Implementation

[0030] The automatic rebar scrap collection device 1 of the present invention is used to collect the remaining section of a rebar after it has been cut, such as... Figure 1 and Figure 2As shown, the collecting device 1 includes a mounting frame 11, a rotating feeding trough 12, a supporting device 14, and a controller. The mounting frame 11 is horizontally positioned and, in this example, is supported by a support frame 18. The rotating feeding trough 12 is positioned along the length of the mounting frame 11, meaning it is parallel to the mounting frame 11; in this embodiment, they are at the same height. The rotating feeding trough 12 includes two opposing side walls and a bottom wall for accommodating the reinforcing bars to be cut, which are also parallel to the length direction of the rotating feeding trough 12. One side wall or bottom wall of the rotating feeding trough 12 is hinged to the mounting frame 11 near the side wall; in this embodiment, the bottom wall of the rotating feeding trough 12 is hinged to the mounting frame 11 near the side wall via a hinge 13. The supporting device 14 is mounted on the mounting frame 11 and located below the rotating feeding trough 12. The supporting device 14 has a support member 1414 that can support the bottom of the rotating feeding trough 12 and can also be horizontally separated from the bottom of the rotating feeding trough 12. "Leaving the bottom of the rotary feed trough 12" means that the two do not overlap in the vertical direction. When the support member 1414 supports the bottom of the rotary feed trough 12, the rotary feed trough 12 is in a horizontal position. When the support member 1414 leaves the bottom of the rotary feed trough 12, the rotary feed trough 12 rotates, and the internal steel bars automatically fall down. The controller controls the action of the support device 14 to make the support member 1414 support or leave the bottom of the rotary feed trough 12, thereby realizing the automatic unloading of excess steel bars.

[0031] With the automatic rebar scrap collection device 1 of the present invention, after the rebar cutting is completed, the supporting device 14 is controlled to move the supporting member 1414 away from the rotating feeding trough 12. The rotating feeding trough 12 rotates around its connection point with the mounting frame 11, tilting the rebar out and automatically unloading it entirely by gravity. This not only shortens the auxiliary operation time but also seamlessly connects with the cycle time of the upstream cutting equipment, avoiding production interruptions caused by delays in manual cleaning and ensuring the continuous and efficient operation of the rebar processing production line. At the same time, it liberates workers from repetitive and heavy physical labor, fundamentally improving the working environment.

[0032] like Figure 1 and Figure 2 As shown, the supporting device 14 includes a plurality of supporting mechanisms 141 arranged along the length of the mounting frame 11. These multiple supporting mechanisms 141 can support the rotating feed trough 12 at multiple positions, thus resulting in a more stable structure. Figure 3As shown, each of the supporting mechanisms 141 includes a mounting base 1411 fixed to the mounting frame 11, a rotating member 1412 mounted on the mounting base 1411 and rotatable in a horizontal plane relative to the mounting base 1411, and a supporting member 1414 hinged to the rotating member 1412 for supporting the feeding trough. The supporting device 14 also includes a drive rod 142 hinged to the rotating member 1412 of all supporting devices 14 and a drive rod 142 drive mechanism for driving the drive rod 142 to perform linear reciprocating motion.

[0033] like Figure 3 As shown, the rotating component 1412 includes a first connecting rod 14121 and a second connecting rod 14123. The first connecting rod 14121 and the second connecting rod 14123 are connected to form a V-shape, that is, one end of the first connecting rod 14121 is connected to one end of the second connecting rod 14123, and the two are at an angle, preferably 30°-90°. A connecting hole is provided at the connection between the first connecting rod 14121 and the second connecting rod 14123. The rotating component 1412 also includes a rotating shaft 1413 that passes through the connecting hole and is tightly fitted to the connecting hole. The rotating shaft 1413 is mounted on the mounting base 1411 by a bearing, that is, the rotating shaft 1413 can rotate relative to the mounting base 1411.

[0034] The ends of the first connecting rod 14121 and the second connecting rod 14123 are each provided with hinged elongated holes 14122 and 14124 extending along their length. The rotating member 1412 also includes a hinge shaft passing through the first hinged elongated hole 14122 of the support member 1414 and the first connecting rod 14121, and a hinge shaft passing through the second hinged elongated hole 14124 of the drive rod 142 and the second connecting rod 14123. The support device 14 also includes a guide ring 14143 fixed to the mounting base 1411. The axis of the guide ring 14143 is perpendicular to the length direction of the rotating feed trough 12, and the support member 1414 passes through the guide ring 14143.

[0035] When the drive rod 142 moves linearly, it drives the rotating component 1412 to rotate. Under the action of the guide ring 14143, the support component 1414 moves linearly to support the rotating feeding trough 12 below it, or moves linearly away from the rotating feeding trough 12 below it, thereby realizing the switching between the position of supporting the rotating feeding trough 12 and the position of leaving the rotating feeding trough 12.

[0036] like Figure 3As shown, the support member 1414 includes a support rod 14141 with one end hinged to the mounting base 1411 and a roller 14142 disposed at the other end of the support rod 14141 for supporting the bottom of the rotating feed trough 12. When the support rod moves, the roller 14142 moves relative to the bottom of the rotating feed trough 12. This movement is achieved by rolling, thereby reducing friction and making the support member 1414 work more smoothly.

[0037] like Figure 3 As shown, the end of the support rod 14141 connected to the first connecting rod 14121 is U-shaped, a part of the first connecting rod 14121 extends into the U-shape, and the U-shaped part of the support rod 14141 is hinged to the first connecting rod 14121.

[0038] like Figure 3 As shown, the support device 14 also includes a plurality of guide brackets 143 fixed to the bottom of the mounting bracket 11. Each guide bracket 143 has a guide hole that allows the drive rod 142 to pass through and slide. The plurality of guide holes together form a guide for the drive rod 142, preventing the drive rod 142 from deflecting, thereby enabling more precise power transmission.

[0039] The automatic rebar scrap collection device 1 also includes a transport mechanism (not shown in the figure) located below the rotating feed trough 12. The rebar scraps fall directly onto the transport mechanism. When a large amount of rebars accumulates, the transport mechanism transports the rebar scraps to a designated location.

[0040] This invention also provides a fully automatic rebar cutting system, such as... Figure 1 and Figure 2 As shown, the feeding system includes a cutting device for cutting reinforcing bars and an automatic reinforcing bar scrap collection device 1 as described above. The mounting frame 11 is also fixed with a fixed feeding trough 15. One end of the fixed feeding trough 15 is close to the cutting device for feeding the reinforcing bars to the cutting device, and the other end is connected to the rotating feeding trough 12 to form a combined feeding trough. The two are spliced ​​together but not connected, so the rotating feeding trough 12 can rotate independently. The combined feeding trough is equipped with a robotic arm 16 for clamping the reinforcing bars. The feeding system also includes a robotic arm drive mechanism 17 that drives the robotic arm 16 to move along the length of the feeding trough. The controller controls the actions of the cutting device, the robotic arm 16, and the robotic arm drive mechanism 17.

[0041] The fully automatic rebar cutting system of the present invention provides a complete conveying channel for rebar from the waiting area to the cutting station by a combined feeding trough formed by splicing a fixed feeding trough 15 and a rotating feeding trough 12. Under the command of the controller, the robotic arm 16 moves back and forth along the length of the feeding trough, which can push the rebar to the cutting device. After cutting, the robotic arm 16 sends the rebar residue into the area of ​​the rotating feeding trough 12, and rotates the feeding trough 12 to unload the rebar residue. The whole process does not require manual transfer, eliminates waiting and stoppage between processes, and greatly improves the overall cycle time and output efficiency of the production line.

[0042] The present invention also provides an automatic method for collecting surplus steel bars, which uses the feeding system described above to collect surplus steel bars, including the following steps:

[0043] S1, with the support member 1414 supporting the bottom of the rotating feed trough 12, the robot arm 16 is controlled to clamp the steel bar residue, and the robot arm drive mechanism 17 is controlled to drive the robot arm 16 to move so that the steel bar residue is completely moved to the rotating feed trough 12.

[0044] S2, control the drive rod 142 drive mechanism to drive the drive rod 142 to move linearly, so that the support 1414 leaves the bottom of the rotating feed trough 12. The rotating feed trough 12 rotates to make the steel bar scrap fall. In this embodiment, the steel bar scrap falls onto the transport mechanism.

[0045] Step S3 involves transporting the leftover steel bars to a designated location via a transport mechanism. The transport mechanism automatically receives and transfers the leftover materials, creating a complete unmanned logistics closed loop from cutting and unloading to the collection of leftover materials, which significantly improves the material turnover efficiency of the workshop.

[0046] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art to the present invention within its spirit and scope of protection also fall within the scope of protection of the present invention.
