The use process of the embodiment of the present invention:

When the pipe cutting machine needs to process pipes, the automatic material warehouse automatically fetches materials according to the pipe type required by the pipe cutting machine. The automatic pipe feeding device according to the pipe type required by the pipe cutting machine, the program controls the separation motor 3.3 to drive the separation chain to drive The separation assembly 3.19 moves along the separation slide 3.9, so that the distance between the first inclined side surface 3.19.1 and the parallel surface 3.21.1 is automatically adjusted to be equal to the shape of the pipe; at the same time, the program controls the stopper motor to drive the stopper chain, thereby Drive the stopper assembly to move along the stopper slide 3.17, so that the distance between the receiving surface 3.18.1 and the first oblique side 3.19.1 is automatically adjusted to be equal to the external dimension of the pipe; after the adjustment, the automatic hopper will be a bundle The pipe is sent to the material receiving device 2, and the material pulling motor 10 drives the rope assembly 2.2, thereby driving the feeding end of the material receiving frame 2.1 to turn upwards around the discharge end of the material receiving frame 2.1, and the one sent from the automatic material warehouse The bundle of pipes is turned over to the feeding side of the distributing device 3, and the receiving rack 2.1 remains oblique; a bundle of pipes is stacked on the first oblique side 3.19.1, the contact surface 3.21.2 and the surface of the receiving rack 2.1 , And then the pusher motor 3.1 drives the pusher chain, thereby driving the pusher assembly 3.21 to move upward along the pusher slide 3.13, because the distance between the first oblique side 3.19.1 and the parallel surface 3.21.1 is equal to the outer dimension of the pipe , The resistance surface of the pusher component 3.21 3.21.2 The resistance can only push the pipe upward in a single-layer, non-stacked form. When the infrared sensor 3.20 detects that a pipe falls into the stopper assembly, the outer red sensor sends a signal to control the push The feed motor 3.1 reverses to make the pusher assembly 3.21 retreat to the initial point; the initial state of the second cylinder 3.23 is extended to the maximum distance. When the infrared sensor 3.20 detects that the pipe falls into the stopper assembly, it drives the second cylinder 3.23 The piston rod retracts and the pipe is sent to the bottom of the measuring device 4. The pressure plate 4.1 of the measuring device 4 initially drops to the lowest point by its own weight, but the pressure plate 4.1 is still placed on top of the pipe, and then the first part of the measuring device 4 The piston cover of a cylinder 4.3 drives the connecting plate 4.4 to move toward the pipe, and the pressing plate 4.1 moves along with the connecting plate toward the pipe until the pressing surface 4.1.1 of the pressing plate 4.1 touches the measuring surface of the pipe. When the piston rod of the first cylinder 4.3 continues to extend towards the pipe to its maximum value, the connecting plate 4.4 moves relative to the pressure plate 4.1 towards the direction of the pipe groove, so that the displacement sensor 4.2 is continuously compressed, and the displacement is determined by the compression of the displacement sensor 4.2. The difference of the amount of measurement measures the outer dimensions of the pipe, so as to determine whether the model of the pipe is the model that needs to be processed by the pipe cutting machine; if not, the stopper motor drives the stopper assembly to slide up along the stopper slide 3.17, and the pipe Push to the pusher assembly 3.21, and then switch the pipe; if it is, the stopper motor drives the stopper assembly to move down along the stopper slide 3.17, when the bearing surface 3.18.1 of the stopper assembly drops below the 5.12 conveyor belt On On the surface, the upper surface of the conveying belt 5.12 transmits the pipe to the lifting device, and the limit column 5.3 restricts the continuous transmission of the pipe.

The center point of, rises to the specified fixed height; the servo motor drives the first baffle 5.2 to collide with one end of the pipe, and the other end of the pipe collides with the second baffle 5.1. The servo motor calculates the length of the pipe by the difference of the moving distance. Determine the cutting distance of the pipe to the pipe cutting machine; after the servo motor measures the length, the conveying motor drives the manipulator to move along the pipe conveying direction, the clamping motor drives the upper clamp 5.9 and the lower clamp 5.8 to simultaneously clamp each other, and the manipulator clamps After the pipe, the lifting motor reverses to drive the lifting device down, and the conveying motor continues to drive the manipulator to move along the pipe conveying direction until the center point of the pipe coincides with the center point of the pipe cutter clamp; after the pipe cutter clamps the pipe , The clamping motor reversibly drives the upper clamp 5.9 and the lower clamp 5.8 to open apart, and the conveying motor reverses to drive the manipulator back to the initial point. When the pipe cutting machine still needs the same type of pipe, repeat the above steps for feeding.

If the pipe cutting machine needs another type of pipe, the pulling motor 10 reverses to drive the pulling frame back to the initial point; the automatic storage hopper takes away the remaining pipes; the automatic storage hopper then takes the other required by the pipe cutting machine The type of pipe is conveyed to the receiving device 2; the separation motor 3.3 drives the separation assembly 3.19 to move along the separation slide 3.9, and automatically adjusts the distance between the first oblique side 3.19.1 and the parallel surface 3.21.1 to be the outer dimension of the pipe , The stopper motor drives the stopper assembly to move along the stopper slide 3.17, and automatically adjust the distance between the receiving surface 3.18.1 and the first oblique side 3.19.1 to the shape of the pipe; repeat the above steps after the adjustment is completed.
