DETAILED DESCRIPTION

[0015] See also Figure 1-4 The present embodiment is a billet unloading device, which is used for unloading billets on the slide rail 1 of the elevator 100. The slide rail 1 has a feeding end and a discharging end. The billet unloading device includes: a lever 2, which is arranged above the slide rail 1; and a driving member 3, which is transmission-connected to the lever 2; the driving member 3 drives the lever 2 to rotate, and the lever 2 responds to the action of the driving member 3 to push the billet retained on the slide rail 1 and close to the discharging end to leave the slide rail 1.

[0016] The present invention provides a lever 2 and a driving member 3. When the steel billet on the slide rail 1 stops, the driving member 3 can drive the lever 2 to move the steel billet so that the steel billet can be unloaded normally, thereby improving the unloading smoothness.

[0017] Furthermore, the height of the slide rail 1 is gradually reduced from one end close to the steel billet to the other end, so that the steel billet rolls or slides along the slide rail 1 under the action of gravity.

[0018] The shifting rod 2 is bent to form a shifting end 21 , so as to increase the contact area between the shifting end 21 and the steel billet when the shifting end 21 rotates to the steel billet.

[0019] In this embodiment, the driving member 3 drives the lever 2 to perform circular motion, so that after the stopped billet is moved, the lever 2 continues to rotate to the top of the slide rail 1 without being limited in rotation by other billets.

[0020] Preferably, there are multiple levers 2, and they are arranged at intervals along the length direction of the steel billet. When the lever 2 rotates, it can simultaneously move multiple locations of the steel billet, thereby improving the moving efficiency and moving accuracy.

[0021] Furthermore, the billet lowering mechanism further includes a plurality of first support frames 4, and a rotating shaft assembly 5 mounted on the first support frames 4. The rotating shaft assembly 5 is respectively connected to the driving member 3 and the lever 2. The driving member 3 can drive the rotating shaft assembly 5 to rotate, thereby driving the lever 2 to rotate. In this embodiment, the driving member 3 is specifically a reduction motor.

[0022] Reference Figure 1 , Figure 3 and Figure 4 As shown, the rotating shaft assembly 5 includes a bearing seat 51 and a rotating shaft 52. There are multiple bearing seats 51, which are respectively fixed on multiple first support frames 4. The rotating shaft 52 is inserted into the bearing seat 51, and the shifting rod 2 is fixedly sleeved on the rotating shaft 52. In this embodiment, the end of the shifting rod 2 away from the material shifting end 21 forms a connecting end 22, and the connecting end 22 is provided with a connecting hole 221 sleeved on the rotating shaft 52. Preferably, the inner wall of the connecting hole 221 is recessed outwardly with a limiting groove 222, and correspondingly, the rotating shaft 52 is provided with a convex rib adapted to the limiting groove 222, so as to limit the axial rotation of the shifting rod 2 after the shifting rod 2 is sleeved on the rotating shaft 52. The bearing seat 51 includes a bearing seat body 511 and a bearing 512 fixed on the bearing seat body 511, and the rotating shaft 52 is inserted in the bearing 512.

[0023] Preferably, since the span between the first support frames 4 at both ends is relatively large, in order to avoid deformation caused by the excessive length of the rotating shaft 52, in this embodiment, there are multiple rotating shafts 52, and the rotating shafts 52 are connected to each other through a connecting sleeve 53. Specifically, the rotating shaft 52 is inserted into the connecting sleeve 53, and it can be interference fit with the connecting sleeve 53, or fixed by a threaded fastener, which is not limited in the present invention.

[0024] Further, see Figure 1 , Figure 2 and Figure 5As shown, the billet unloading device further includes a buffer assembly 300 for buffering the billet, and the buffer assembly 300 is directly opposite to the discharge end of the slide rail 1. There is a buffering distance between the discharge end of the slide rail 1 and the buffer assembly 300, and the buffer assembly 300 is configured to limit the sliding stroke of the billet.

[0025] The buffer assembly 300 includes a second support frame 6, an elastic member 7 mounted on the second support frame 6, and a baffle 8 mounted on the elastic member 7 to resist the steel billet. When the steel billet flows from the steel billet to the end of the slide rail 1, the buffer assembly 300 can block the steel billet to prevent the steel billet from flowing away from the collection area at the end of the slide rail 1 due to the excessive speed of the steel billet. In this embodiment, the elastic member 7 is specifically a spring. Preferably, there are multiple groups of buffer assemblies 300, and they are respectively located between two adjacent first support frames 4, so as to buffer multiple positions of the steel billet and further improve the buffering effect.

[0026] In addition, the billet unloading device further includes a laser sensor 200. The discharge end of the slide rail 1 has an empty state and a billet retention state. The laser sensor 200 is configured to determine the state of the discharge end of the slide rail 1. Specifically, the laser sensor 200 is directly opposite to the discharge end of the slide rail 1 to emit a laser to the discharge end, thereby monitoring the discharge end of the slide rail 1 in real time. When the laser sensor 200 detects a retained billet, it sends a command to the driving member 3 to drive the lever 2 to push the retained billet away from the slide rail 1.

[0027] In summary, the present invention provides a lever and a driving member. When the steel billet on the slide rail stops, the driving member can drive the lever to move the steel billet so that the steel billet can be unloaded normally, thereby improving the smoothness of unloading. A buffer assembly is provided at the end of the slide rail, which can buffer the steel billets flowing to the end of the slide rail to ensure that the steel billets flow to the collection area.
