In the existing storage and transportation of ingots in an extrusion production line, usually a batch of ingots can only be stored in a unified length, and then they are transported by overhead cranes or forklifts. There are also cases where manual instructions are sent to complete the transportation through ingot-carrying trolleys. These storage and transportation methods have a slow rhythm, cannot differentially change the ingot length at any time, have a low degree of automation, and there are certain safety hazards.

A reflector is installed on the pushing bar trolley, and the reflector cooperates with the laser rangefinder.

[0011] The cylinder, the variable frequency motor reducer, and the laser rangefinder are all electrically connected to the PLC control system.

[0012] The ingot sawing machine includes a saw blade, a saw blade feeding mechanism, a saw blade rotating mechanism, and a sawdust collecting mechanism.

[0018] An intelligent storage and transportation control method for ingots in an extrusion production line, using an intelligent storage and transportation control system for ingots in the extrusion production line, includes the following steps:

[0019] Step 1) Input the length L of the ingots required for this batch through the HMI human-machine interface, and the PLC control system controls the feeding mechanism to convey the casting rod;

[0020] Step 2) After the PLC control system receives the signal from the feeding induction switch, it controls the feeding roller table to lift the casting rod from the lower position to the upper position, and then sends a signal to the pusher trolley at the rear. The clamp of the pusher trolley clamps the tail of the casting rod and advances along the track;

[0021] Step 3) When the pusher induction switch sends a signal to the PLC control system, the pusher trolley stops. After that, the PLC control system controls the pusher trolley to continue moving forward with the casting rod for a distance L;

[0022] Step 4) The PLC control system controls the ingot sawing machine to advance and saw the casting rod into ingots with a length of L.

[0023] Step 5) The movable pawl of the ingot clamping mechanism that has been waiting at the ingot grasping position descends under the control of the PLC control system to grasp the ingot and rise.

[0024] In step 4), when the ingot sawing machine retracts to the initial point, the PLC control system judges whether the length of the sawed casting rod is greater than L through the pusher induction switch. When the judgment is true, the pusher trolley continues to move forward with the casting rod for a distance L, and this operation is repeated until the PLC control system judges that the length of the sawed casting rod is less than L and the loop ends.

[0040] Unless otherwise specified, the terms used herein (including technical terms) have the ordinary meaning understood by those skilled in the art.

[0041] Embodiment 1:

[0042] This embodiment provides an intelligent storage and transportation control system for ingots in an extrusion production line, which includes a loading mechanism 1, a pusher trolley 2, an ingot sawing machine 3, a roller table 4 after sawing, an ingot clamping mechanism 5, an ingot storage table 6, and a PLC control system 8. The pusher trolley 2 is located between the loading mechanism 1 and the ingot sawing machine 3. The roller table 4 after sawing is located behind the ingot sawing machine 3. The ingot clamping mechanism 5 includes a manipulator and a track 11. The track 11 is provided above the end of the roller table 4 after sawing and is perpendicular to it. The ingot storage table 6 is provided below the track 11. A pusher induction switch 206 is installed between the ingot sawing machine 3 and the pusher trolley 2. An ingot 10 in-place induction switch is installed on the roller table 4 after sawing.

[0043] The PLC control system 8 is electrically connected to an HMI human-machine interface 7. The loading mechanism 1, the pusher trolley 2, the ingot sawing machine 3, the roller table 4 after sawing, the ingot clamping mechanism 5, the pusher induction switch 206, the ingot 10 in-place induction switch, and the ingot storage table 6 are all electrically connected to the PLC control system 8.

[0044] The pusher induction switch 206 is used to send a signal to the PLC control system 8 to determine the base point of the forward distance L of the pusher trolley 2 driving the casting rod 9, and the length of the remaining casting rod 9 after the casting rod 9 is sawed, so that the PLC control system 8 can judge whether the next sawing can be performed. The ingot 10 in-place induction switch is used to send a signal to the PLC control system 8 after the ingot 10 is sawed, control the roller table 4 after sawing to convey the ingot 10 below the ingot clamping mechanism 5, and finally the ingot clamping mechanism 5 places the ingot 10 on the ingot storage table 6.

[0045] Specifically, the application process of the intelligent storage and transportation control system for ingots in the extrusion production line provided in this embodiment is as follows:

[0046] The required length L of the ingot 10 is input through the HMI human-machine interface 7. Then, the PLC control system 8 controls the feeding mechanism 1 to convey the casting rod 9. After the conveyance is in place, the pusher trolley 2 clamps the tail of the casting rod 9. Under the control of the PLC control system 8, the pusher trolley 2 advances a certain distance. When the pusher induction switch 206 sends a signal to the PLC control system 8, the pusher trolley 2 stops. Then, the pusher trolley 2 is controlled to advance by the length L of the ingot 10, and the ingot sawing machine 3 performs sawing. The sawn ingot 10 is conveyed by the post-saw roller table 4 to below the ingot clamping mechanism 5. Finally, the ingot clamping mechanism 5 places the ingot 10 on the ingot storage table 6.

[0047] After the ingot sawing machine 3 completes one sawing operation, it retracts to the initial position. When the PLC control system 8 determines through the pusher induction switch 206 that the length of the remaining casting rod 9 is greater than L (there is an induction plate at the front end of the vehicle body, that is, the distance between the pusher induction switch 206 and the induction plate satisfies L), it controls the pusher trolley 2 to advance by the length L of the ingot 10 for secondary sawing; the above process is repeated until sawing cannot be performed. The pusher trolley 2 releases the remaining residue, which is conveyed by the post-saw roller table 4 to below the ingot clamping mechanism 5, and the ingot clamping mechanism 5 places the ingot 10 in a designated place.

[0051] The casting rod 9 is conveyed by the feeding table 101 and then falls onto the feeding roller table (in the initial state, the feeding roller table is lower than the feeding table 101). When the feeding induction switch 104 senses the presence of the casting rod 9, it sends a signal to the PLC control system 8. The PLC control system 8 controls the feeding roller table to rise. Then, the pusher trolley 2 clamps the tail of the casting rod 9 and advances along the rails. Among them, the feeding roller table is composed of feeding supporting rollers 102.

[0084] Step 1) Input the length L of the ingots 10 required for this batch through the HMI human-machine interface 7, and the PLC control system 8 controls the feeding mechanism 1 to convey the casting rod 9;

[0085] Step 2) After the PLC control system 8 receives the signal from the feeding induction switch 104, it controls the feeding roller table to lift the casting rod 9 from the lower position to the upper position, and then sends a signal to the pusher car 2 at the rear.

[0089] Among them, the PLC control system 8 judges whether the pusher car 2 is at the rear limit through the laser rangefinder 201. A post-saw roller table induction switch is installed on the post-saw roller table 4. When the post-saw roller table induction switch sends a signal, the post-saw roller table 4 stops conveying, and the ingot 10 reaches the ingot grasping position.

[0090] Embodiment 11:

[0091] On the basis of Embodiment 10, this embodiment provides a method for controlling the intelligent storage and transportation of ingots in an extrusion production line. In step 4), when the ingot sawing machine 3 retracts to the initial point, the PLC control system 8 judges whether the length of the sawed casting rod 9 is greater than L through the pusher induction switch 206. When the judgment is true, the pusher car 2 continues to advance the casting rod 9 by a distance L, and this operation is repeated until the PLC control system 8 judges that the length of the sawed casting rod 9 is less than L and the loop ends.
