Technical Field

[0002] Laser tube cutting machines have the advantages of high precision, high cutting efficiency, neat incisions and low production costs. Therefore, laser tube cutting machines have been widely used in the field of tube processing. In the entire processing process, the loading process is a more important link, which determines the processing efficiency and processing rhythm of the entire laser tube cutting machine.

[0003] At present, in order to increase the feeding speed of pipes, most existing laser pipe cutting machines use semi-automatic feeding devices or fully automatic feeding devices. Among them, although the semi-automatic feeding device has low cost, it requires workers to manually arrange the pipes on the conveyor rack intermittently, so it has a long and high-intensity labor, which easily causes the workers to feel physically tired. Based on this, it not only reduces the feeding efficiency of the pipes, but also increases the risk of pipe falling accidents during the pipe handling process.

[0004] The fully automatic feeding device generally adopts chain feeding, uses a cylinder or motor to lift the pipe to the position of the pneumatic clamp, and then controls the pneumatic clamp to move and clamp the pipe, and feeds the pipe into the center of the laser pipe cutting machine. However, although the existing fully automatic feeding device reduces the workload of the staff, this fully automatic feeding device has problems such as complex structure and high equipment cost in actual production.

Among them, the inner wall of the silo is paved with a shock-absorbing pad 2-7, and a tensioning belt 2-11 is provided in the silo. One end of the tensioning belt 2-11 is fixed to the rear end of the silo through a pressure plate 1 2-9, and the other end of the tensioning belt 2-11 is fixed to the reel 2-14 after passing through the support wheel 2-12 at the front end of the silo through a pressure plate 2-15. The reel 2-14 is rotatably installed on the support frame 2-1 through a seat bearing 2-8 or other bearings, and the rotating shaft 2-18 of the reel 2-14 is transmission-connected with a rotating drive mechanism. In this way, the reel 2-14 can be driven to rotate through the rotary drive mechanism, the tensioning belt 2-11 can be slowly tightened through the reel 2-14, and the pipes placed in the tensioning belt 2-11 can be driven to rise, so as to transport the pipes one by one to one place on the feeding slope.

[0034] In addition, as a preferred embodiment, the utility model can also set a blocking plate 2-10 in the middle or lower part of the rear end of the silo, and pass the tensioning belt 2-11 through the blocking plate 2-10, so as to constrain the position of the tensioning belt 2-11 through the blocking plate 2-10 to prevent the pipe and other materials from excessively rolling backward in the tensioning belt 2-11. The support seat 2-13 used to support the support wheel 2-12 is installed on the side of the feeding ramp 1 through an adjustable height structure, such as a matching installation structure of a bolt and an elongated hole, so that the staff can adjust the support wheel 2-12 to a suitable height.

[0035] And if Figure 1 , Figure 6 As shown, all the reels 2-14 of the feeding monomers 2 are connected to the same rotary drive mechanism, and the rotary drive mechanism is connected to the photoelectric start-stop mechanism.

When the trigger photoelectric plate 5-3 moves horizontally with the nut seat, the trigger photoelectric plate 5-3 can trigger the fall-back-in-place photoelectric 5-7, the fall-limit photoelectric 5-6, the lift-in-place photoelectric 5-5, and the lift-limit photoelectric 5-4 at the corresponding position to shut down the system, thereby playing a role of double protection. In this way, the utility model can realize the follow-up of the trigger photoelectric plate 5-3 when the ball screw 3-7 rotates with the transmission shaft 4-4 and the winding wheel 2-14, and when the winding wheel 2-14 controls the tensioning belt 2-11 to be tightened to the limit position, the trigger photoelectric plate 5-3 is controlled to move to the corresponding position, and sequentially triggers the lifting in place photoelectric 5-5 and the lifting limit photoelectric 5-4, triggering the system to shut down; when the winding wheel 2-14 controls the tensioning belt 2-11 to be relaxed to the limit position, the trigger photoelectric plate 5-3 is controlled to move to the corresponding position, and sequentially triggers the falling limit photoelectric 5-6 and the falling in place photoelectric 5-7, triggering the system to shut down.

The frame assembly 3 is provided with a blocking mechanism 2 at the upper position of the high end of the feeding ramp 1, and the blocking mechanism 2 can block the conveying space above the high end of the feeding ramp 1; the side of the high end of the feeding ramp 1 is provided with a linkage limit sensor mechanism 1 and a linkage limit sensor mechanism 2 from back to front in sequence, and the side of the low end of the feeding ramp 1 is provided with a linkage limit sensor mechanism 3 and a material ejection mechanism from back to front; and the linkage limit sensor mechanism 1 and the linkage limit sensor mechanism 2 are connected in communication with the linkage limit sensor mechanism 3, the material ejection mechanism, and the rotary drive mechanism. The middle part or the lower end of the feeding ramp 2 is provided with a blocking mechanism 1 and a linkage limit sensor mechanism 4, and the position of the blocking mechanism 1 is opposite to the position of the correction mechanism; the linkage limit sensor mechanism 4 is connected in communication with the correction mechanism and the blocking mechanism 1. The upper end of the feeding platform is provided with a linkage limit sensor mechanism 5 and a material blocking platform.

[0037] Specifically, the linkage limit sensor 1 and the linkage limit sensor 4 both adopt the cooperation of the limit plate and the inductive limit sensor, and taking the linkage limit sensor 1 as an example, the linkage limit sensor 1 includes an L-shaped limit plate 2-23, and the corner of the L-shaped limit plate 2-23 is rotatably installed on the side of the feeding slope 1, and the horizontal section of the L-shaped limit plate 2-23 is located in front of the hinge point between the L-shaped limit plate 2-23 and the feeding slope 1, and the horizontal section of the L-shaped limit plate 2-23 is in a free state. In the state, it is higher than the upper surface of the feeding slope 1; the vertical section of the L-shaped limit plate 2-23 is located below the hinge point between the L-shaped limit plate 2-23 and the feeding slope 1, and an inductive limit sensor 2-22 is arranged on one side of the vertical section of the L-shaped limit plate 2-23. When the material on the feeding slope 1 presses the horizontal section of the L-shaped limit plate 2-23, the vertical section of the L-shaped limit plate 2-23 can trigger the inductive limit sensor 2-22, and the inductive limit sensor 2-22 is communicated with the rotation drive mechanism. At this time, the utility model can sense whether the pipe at the tensioning belt 2-11 can slide down to a place on the feeding slope through the cooperation between the L-shaped limit plate 2-23 and the inductive limit sensor 2-22, and when it determines that the pipe in the tensioning belt 2-11 has already slid down to a place on the feeding slope, it can transmit a signal to the controller to control the rotating drive mechanism to stop running, so as to prevent the pipe in the tensioning belt 2-11 from piling up too high.

[0038] Similarly, the utility model can sense whether the pipe has slipped to a stopper mechanism of the feeding ramp 2 through the cooperation between the L-shaped limit plate 2-24 and the inductive limit sensor 2-25, and when it is determined that the pipe has been able to slide to a stopper mechanism, it can control the correction mechanism to perform corresponding end correction actions according to the signal, and the stopper mechanism 1 performs a discharge action.

And if the swing arm limit sensor 2-21 detects that there are pipes arranged at the high end of the feeding ramp 1, it can transmit a signal to control the action of the blocking mechanism 2 to block the material conveying space above the feeding ramp 1 to prevent the pipes on the feeding ramp 1 from squeezing each other; on the contrary, when the pipe cutting machine transmits a signal to require profiles, if the swing arm limit sensor 2-20 detects that there are no pipes arranged at the low end of the feeding ramp 1, it can transmit a signal to control the action of the blocking mechanism 2 to ensure that the pipes in the tensioning belt 2-11 can pass smoothly through the material conveying space above the feeding ramp 1, thereby realizing the corresponding feeding action; at the same time, if the swing arm limit sensor 2-20 and the inductive limit sensor 2-22 do not detect any pipes, they can issue a feeding alarm and control the reverse rotation of the rotary drive mechanism to drop the tensioning belt 2-11 back to the waiting height for feeding; on the contrary, if there are pipes, they can transmit a signal to control the lifting mechanism to perform the feeding action.

[0040] The lifting mechanism includes a lifting cylinder 2-5, the cylinder body of the lifting cylinder 2-5 is obliquely installed on the side of the feeding slope one, and a lifting plate 2-6 is installed on the end of the piston rod of the lifting cylinder 2-5. The upper end of the lifting plate 2-6 is inclined, and its inclination angle is consistent with the inclination angle of the feeding slope one and the inclination angle of the feeding slope two.
