Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to pipe feeding equipment and a feeding method. Background Art

[0002] In order to improve production efficiency and processing speed, laser tube cutting machines are equipped with automatic loading racks to continuously provide tubes for laser cutting machines without manual intervention. Existing automatic loading racks are mostly to arrange multiple tubes placed in the material placement component in order on the discharge component, and to separate one tube from multiple tubes through the lifting component, and then the pushing component pushes the tube to the subsequent laser tube cutting machine. In actual production, when the tubes are transferred to the discharge component for arrangement, it is particularly easy to get stuck, especially between the feed trough and the limit adjustment plate, so the machine needs to be stopped for debugging to solve the problem, which affects the production rhythm of automated production.

[0003] Patent No. CN202411055247.3 discloses an automatic continuous pipe cutting device, including a side hanging frame, a gantry, a laser cutting assembly, a rear chuck assembly, a front chuck assembly, and an automatic feeding rack and a receiving rack. The automatic feeding rack includes at least three groups of rack modules arranged at intervals, each rack module includes a base frame, a corner frame arranged on the base frame, a material distribution area arranged at the top corner of the corner frame, a first material blocking assembly for intercepting and releasing the pipes in the material distribution area, and a material distribution assembly for screening multiple pipes in the material distribution area into a single pipe. The corner frame is provided with an inlet bevel and an outlet bevel shaft. An open material distribution area is formed by the cooperation of the outlet bevel shaft and the first material blocking assembly. The material storage pulling assembly only needs to pull multiple pipes to the material distribution area. The pushing strips and stacking pushing blocks of the material distribution assembly work together to accurately screen multiple irregularly placed pipes in the material distribution area into a single pipe, thereby solving the problem of material jamming. When feeding some thin-walled and long pipes, the texture of such pipes is relatively soft. During the feeding process, two pipes are prone to cross each other. After the crossed pipes enter the dividing area 13, because the dividing area 13 is U-shaped with an opening upward, the movable space at the end of the pipe is small, and the material may get stuck. The dividing assembly 3 cannot push the cross-stacked pipes back into the material storage area 41. At this time, the machine needs to be stopped for manual adjustment, which is inefficient. Therefore, the present invention proposes pipe feeding equipment and a feeding method. Summary of the invention

[0023] By arranging a material straightening component below the material depot pulling component, each time the material depot pulling component releases the pipe on the cloth belt downward, after the cloth belt contacts the first inclined surface, the pipe will slide and roll down along the first inclined surface, thereby straightening the pipes and separating the crossed pipes, reducing the probability of pipe crossing and improving the success rate of material loading;

[0024] The cloth belt is provided with a pushing block. When a very small amount of pipe material is left on the cloth belt, the cloth belt can push against the pipe material through the pushing block to pull the pipe material, thereby ensuring that the pipe material can be smoothly pulled to the material distribution area.

[0037] The material warehouse pulling assembly includes a cloth belt 9, a tightening wheel 10, a servo motor 25, a support block 26 and a column 11. The servo motor 25 is arranged at the lower part of the bracket 7, and the column 11 is arranged on the side of the bracket 7 away from the material distribution area. The servo motor drives the tightening wheel 10 to rotate around the second horizontal direction. The support block 26 is located at the lower part of the material distribution area 23. One end of the cloth belt 9 is wound around the tightening wheel 10, and the middle part of the cloth belt is supported on the support block 26. The other end of the cloth belt 9 is connected to the column 11, and the installation height is higher than the support block 26. A sinking space is formed between the column 11 and the support block 26.

[0038] A material unit is provided at the bottom of the material storage pulling unit 1. The material unit includes a material plate 12 provided on a bracket below the cloth belt. The upper end surface of the material plate is provided as a first inclined surface 13 facing the side where the tensioning wheel is located.

[0039] The cloth belt 9 is connected with a pusher assembly, which includes a pusher block 14 located on the upper surface of the cloth belt 9 and a clamping plate 15 located on the lower surface of the cloth belt 9. The clamping plate 15 and the pusher block 14 are fixed to the cloth belt 9 by bolts.

[0040] The upper end surface of the pusher block 14 is configured as a second inclined surface 16 , and the lower end of the second inclined surface 16 faces the side where the column 11 is located.

[0041] The second inclined surface 16 is provided with a ridge 17 extending along the length direction thereof.

When the material blocking member 18 rotates to the highest point, it is higher than the material distribution area 23 .

[0043] It also includes a material distribution space adjustment component, which includes a slide plate 20, a slide rail, a screw rod 21 and a drive motor 22. The slide rail is arranged on the bracket and guides the slide plate 20 to slide obliquely. The drive motor 22 drives the screw rod 21 to rotate. The screw rod 21 is threadedly matched with the slide plate 20. The axis of the screw rod 21 is parallel to the length direction of the slide rail.

When the pipe enters the material distribution area 23, the pressure rod is pressed, and the pressure sensor monitors the pressure change, thereby monitoring whether the material is coming.

[0045] The initial state of the feeding equipment: the push rod of the first cylinder 5 is extended, so that the material distribution plate 4 extends above the material distribution area, and a temporary storage slot with an opening inclined upward is formed between the material blocking rod 6 and the material distribution area 23. The temporary storage slot can only accommodate a single pipe, and multiple pipes are stacked on the cloth belt 9.

[0046] The working process of the present invention is as follows: the servo motor drives the take-up wheel 10 to reel the cloth belt 9, thereby pulling the pipes stacked on the cloth belt 9 upward so that the front end of the pipes flows into the material distribution area;

[0047] The servo motor drives the cloth belt 9 to reset, so that the remaining pipes sink into the sinking space. At the same time, the push rod of the first cylinder 5 retracts and then extends to complete a material separation action. The friction between the material blocking rod 6 and the frontmost pipe causes it to vibrate, so that the first pipe in the material separation area 23 is separated from the pipes behind. When the pipes are cross-stacked, when the push rod of the first cylinder 5 retracts for the first time, the temporary storage slot is released, and the activity space at the end of the pipe can prevent the end of the pipe from getting stuck. The crossed pipes are returned to the material storage pulling unit 1 under the friction of the cloth belt 9 and the self-weight of the pipe, so there is no need to stop the machine for manual adjustment, which greatly improves the work efficiency.

[0048] The push rod of the first cylinder 5 is retracted, and the second cylinder 19 drives the material blocking member 18 to rotate clockwise, releasing the single pipe in the material distribution area 23, and the pipe slides out along the output inclined axis 8;

[0049] The second cylinder 19 drives the material stopper 18 to reset, and the first cylinder 5 drives the material dividing plate 4 to reset;

[0050] Repeat the above steps to achieve continuous loading.

[0051] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
