In this embodiment, the front-to-back spacing is set to 2 radii of the tubing.
By adopting the ingenious design, when the third telescopic cylinder 320 jacks the retainer plate 310, only one pipe 400 can be lifted, and under the action of the driving mechanism 500, the lifting mechanism 300 takes the pipe 400 to pass over the clamping manipulator 200, so that the clamping manipulator can deliver the pipe 400 to the laser cutting machine one by one.
The working process of the feeding device is as follows: before clamping the tube 400, the lifting mechanism 300 is driven by the driving mechanism 500 to move backward and return to the set position. Then, the clamping robot 200 moves backward relative to the base frame 100 to return to the set position, at this time, the rear side surface of the clamping robot 200 is located at the front side of the rear side surface of the retainer plate 310, and the front-rear distance between the rear side surface of the clamping robot 200 and the rear side surface of the retainer plate 310 is the set diameter of the pipe.
After the pipe 400 moves from the inclined plane to the horizontal plane, since the clamping manipulator 200 returns to the set position, the rear side surface of the clamping manipulator 200 can contact with a pipe located on the horizontal plane and located at the foremost side, at this time, the clamping manipulator 200 plays a positioning role, and then the lifting mechanism 300 works to make the retainer plate 310 only lift the pipe 400 contacting with the clamping manipulator 200.
After the retainer plate 310 lifts the tube 400 higher than the clamping robot 200, the driving mechanism 500 drives the lifting mechanism 300 to move forward to a set position, that is, in front of the clamping robot 200; then, the retainer plate 310 carries the tube 400 to a set height position.
Then, the clamping manipulator 200 moves forward to the set horizontal position, and the first clamping block 210 and the second clamping block 220 approach each other, so that the first clamping block 210 and the second clamping block 220 simultaneously contact the surface of the pipe 400 due to the synchronous motion and the same moving distance of the first clamping block 210 and the second clamping block 220, and the pipe is clamped stably. At this time, the lifting mechanism 300 moves backward to a set position, and is ready to lift the next pipe.
Finally, centre gripping manipulator 200 removes toward laser cutting machine direction, delivers to chuck department with the tubular product level, lets after chuck direct movement one section distance, directly cliies tubular product through its anchor clamps, need not to adjust the high position and the front and back position of tubular product, and the accuracy of material loading promotes greatly to, the chuck takes tubular product to remove toward laser cutting head direction to accomplish the laser cutting of tubular product and handle.
Because the adjacent pipes 400 are in contact with each other, after the pipe a is lifted, the next pipe B moves due to the pushing force applied to the next pipe B, and replaces the position of the previous pipe a, and after the clamping manipulator 200 moves to the right, the pipe B contacts with the clamping manipulator 200 and is lifted by the lifting mechanism 300, so that the above-mentioned work is repeated continuously.
In some embodiments, the drive mechanism 500 comprises: a mounting seat 540, a second guide rail 520, a second slider 530 and a fourth telescopic cylinder 510.

The fixed end of the fourth telescopic cylinder 510 is connected with the mounting base 540 through screws, and the telescopic end of the fourth telescopic cylinder 510 is connected with the movable base 340. When the telescopic end of the fourth telescopic cylinder 510 extends or contracts, the fourth telescopic cylinder 510 can drive the lifting mechanism 300 to move back and forth.
Of course, the driving mechanism 500 may also adopt a transmission mode of a motor and a lead screw, when the motor drives the lead screw to rotate forward or backward, the moving seat 340 screwed with the lead screw is driven to move forward or backward. In addition, a linear module may be used as the driving mechanism 500.
In some embodiments, the material supporting top surface is in a V shape, and is mainly used for feeding a circular tube, so that the tubular product 400 can be kept stable in the lifting process to prevent the tubular product 400 from falling off from the material supporting plate 310, and the tubular product 400 can be positioned, at this time, the tubular product 400 is positioned in the middle of the material supporting top surface, the circular tube is supported by two inclined surfaces of the material supporting plate 310, and when the lifting mechanism 300 drives the circular tube to move forwards, the circular tube can be ensured to be stable, so that the clamping manipulator 200 can conveniently and accurately clamp the tubular product 400.
And, the loading attachment still includes: a blocking rod and a first telescopic cylinder 140.

The fixed end of the first telescopic cylinder 140 is fixedly connected with the base frame 100, and the telescopic end of the first telescopic cylinder 140 is connected with the blocking rod to drive the blocking rod to lift.
Because the pipe drops from the horizontal plane because of rolling easily on the horizontal plane, consequently, set up specially and block the pole, when centre gripping manipulator 200 sent tubular product 400 level to laser cutting machine, produce the effect of blockking to the pipe, prevent effectively that the pipe from moving forward too big and drop on ground on the horizontal plane.
And set up first telescopic cylinder 140 and order about stopping the pole and reciprocate, when centre gripping manipulator 200 cliied tubular product and move forward, can avoid stopping the pole and cause to block the influence to the tubular product that is pressed from both sides.
In addition, the top surface of the supporting plate 120 includes a flat surface and an inclined surface 122, the flat surface and the inclined surface 122 are sequentially arranged from back to front, and the circular tube automatically rolls from the inclined surface to the inclined surface 122 of the supporting plate 120 to contact with the blocking rod.
