Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is for reference. Figures 1 to 4 The automatic bar sawing machine unloading, lifting, and conveying device of this utility model is described in conjunction with the embodiments.

[0023] An automatic bar sawing machine unloading, lifting, and transfer device includes roller A1, roller chain A2, servo motor A3, track frame A4, roller B5, roller chain B6, servo motor B7, oscillating cylinder rotating body 8, oscillating cylinder and connecting plate 9, guide column 10, guide sleeve 11, lifting cylinder 12, base frame 13, rotating bracket (i.e., roller track B14), piston rod baffle 15, push plate 16, push plate cylinder 17, bar stock 18, roller track C19, waste chute 20, waste frame 21, roller track A22, material blocking cylinder 23, roller C24, roller chain C25, servo motor C26, track frame C27, and other components.

[0024] The roller track A22 is placed on the track frame A4 on the ground. Servo motor A3, roller chain A2, and roller A1 are mounted on roller track A22 to drive the bar stock 18 forward on roller track A22. Servo motor B7, roller chain B6, and roller B5 are mounted on the rotating bracket, i.e., roller track B14, to drive the bar stock 18 to rotate and move forward on the rotating bracket 14. Roller track C19 is placed on the track frame C27 on the ground. Servo motor C26, roller chain C25, and roller C24 are mounted on roller track C19 to drive the sawn bar stock 18 forward on roller track C19. A stop cylinder 23 is placed on the side wall of the base frame 13, and its piston rod head is fixedly connected to the piston rod baffle 15 for stopping the material. The pusher cylinder 17 is fixed to the side wall of the roller track C19, and its piston rod head is fixed to the pusher plate 16, which is used to push the defective bar stock 18 into the waste frame 21. The waste chute 20 is placed between the roller track C19 and the waste frame 21 to guide the waste to slide down. The bottom end of the rotating bracket, i.e., the roller track B14, is fixed to the upper end of the swing cylinder rotating body 8, and the swing cylinder rotating body 8 drives the rotating bracket 14 to rotate. The swing cylinder and connecting plate 9 are fixed to the upper end of the guide column 10 and the upper end of the piston rod of the lifting cylinder 12, and the bottom end of the lifting cylinder 12 is fixed to the upper end of the middle plate of the base frame 13. Under the guidance of the guide column 10 and the guide sleeve 11, the piston rod of the lifting cylinder 12 extends and retracts, driving the rotating bracket 14, the swing cylinder rotating body 8, and the swing cylinder and connecting plate 9 to rise and fall.

[0025] During operation, the servo motor C on the roller track C rotates, driving the roller chain C and rollers C to rotate, thereby propelling the sawn bar stock 18 forward on the roller track C. When the image scanning recognition or weighing mechanism determines that the sawn bar stock is unqualified, the piston rod of the baffle cylinder 23 extends, and the baffle plate 15 blocks the unqualified bar stock 18. At the same time, the piston rod of the push plate cylinder 17 extends, and the push plate 16 pushes the unqualified bar stock out of the roller track C and into the waste box 21.

[0026] For qualified bar stock, it continues to move forward on roller track C until it reaches the rotating bracket 14 (i.e., roller track B). At this time, the servo motor B on the rotating bracket 14 rotates, driving the roller chain B and roller B to rotate, thereby driving the qualified bar stock forward on the rotating bracket 14. When the qualified bar stock is driven to the center of the rotating bracket 14, the rotating cylinder 8 drives the rotating bracket 14 to rotate 90 degrees. At the same time, under the guidance of the guide post 10 and the guide sleeve 11, the piston rod of the lifting cylinder 12 extends and retracts, driving the rotating bracket 14 to rise to the lifting height of roller track A.

[0027] Subsequently, the servo motor B spindle on the rotating bracket 14 rotates again, driving the roller chain B and roller B to rotate, thereby driving the qualified bar stock to continue moving forward and enter the roller track A. At this time, the servo motor A spindle on the roller track A rotates, driving the roller chain A and roller A to rotate, thereby driving the qualified bar stock to move forward on the roller track A and enter the next process, completing one work cycle.

[0028] Throughout the process, automated operation is achieved through PLC control, eliminating the need for manual intervention and greatly improving production efficiency and product quality.

[0029] Compared with existing technologies, the automatic bar sawing machine unloading, lifting, and conveying device of this utility model has the following advantages:

[0030] This utility model discloses an automatic bar sawing machine with a compact structure for feeding, lifting, and transferring materials, facilitating automated control and improving production efficiency. PLC control enables automated operation of the entire process, reducing manual operation costs. Equipped with a baffle cylinder and a pusher cylinder, it can automatically identify and separate defective bars, improving product quality. The design of the rotating bracket and lifting cylinder realizes the lifting and transfer of bars, increasing the flexibility of the equipment.
