Description

Automatic feeding mechanism Technical Field

[0001] This utility model relates to the field of pipe processing equipment, and in particular to an automatic material receiving mechanism. Background Technology

[0002] With the development of laser cutting technology, laser cutting has been widely used in manufacturing, such as laser cutting of pipes. In order to reduce the labor intensity and feeding accuracy caused by manual material handling, existing laser pipe cutting machines are generally equipped with automatic receiving mechanisms to assist in material handling, that is, to transport the processed pipes one by one to the material handling station.

[0003] The existing automatic receiving mechanism supports the pipe in the middle of the flip plate when receiving the pipe, and then drives the flip plate to flip and tilt it, so that the pipe slides down the tilted surface of the flip plate onto the receiving rack. However, because there is a large height distance between the middle of the flip plate and the receiving rack, the pipe will fall from the flip plate onto the receiving rack in a hard free fall, which can easily damage the pipe. Moreover, due to the large impact force of the fall, the pipe is easy to fall off the receiving rack. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic receiving mechanism that can receive pipes after pipe cutting, reduce the impact force of pipe cutting, improve the reliability of pipe cutting, prevent damage to pipes, and prevent pipes from falling out of the receiving rack.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An automatic receiving mechanism includes a tilting plate and a receiving rack disposed on one side of the tilting plate, and also includes a buffer assembly. The buffer assembly includes a first cylinder, a second cylinder, a slide block, and a telescopic stop bar. The tilting plate is provided with a strip-shaped through groove, and a sliding groove is provided below the strip-shaped through groove. The slide block is slidably disposed in the sliding groove, and its lower side is fixedly connected to the first cylinder. The output end of the first cylinder is fixedly connected to the telescopic stop bar. The middle part of the slide block is provided with a through hole, and the telescopic stop bar is disposed in the through hole. The second cylinder is fixedly connected to the side of the tilting plate away from the receiving rack, and its output end is fixedly connected to the side of the slide block away from the receiving rack.

[0007] Preferably, a third cylinder and a support plate are hinged to the lower side of the tilting plate, with the support plate located on the side of the third cylinder away from the receiving frame.

[0008] Preferably, a first support is fixedly connected to the lower side of the support plate, and a rack is connected to one side of the support plate. The bottom of the third cylinder is hinged to the first support. A gear is meshed with the rack. A gearbox is connected to the gear. A motor is connected to the gearbox. A second support is fixedly connected to the second support. An inverted slider is fixedly connected to the second support. A slide rail is connected to one side of the support plate. The inverted slider is slidably connected to the slide rail.

[0009] Preferably, a translation frame is connected to the lower side of the second support, a base is slidably connected to the lower side of the translation frame, and a push-pull plate is connected to the side of the translation frame away from the receiving frame. A fourth cylinder is connected to the side of the base away from the receiving frame, and the output end of the fourth cylinder is fixedly connected to the push-pull plate.

[0010] Preferably, two guide grooves are symmetrically provided on both sides of the slide groove, and two guide blocks are symmetrically connected on both sides of the slide block, with the two guide blocks slidingly disposed in the two guide grooves respectively.

[0011] Preferably, a rubber sleeve is fitted onto the outer side of the telescopic stop bar.

[0012] Preferably, one side of the receiving rack is connected to an inclined limiting plate, and the other side is connected to an arc-shaped limiting plate, with a first limiting plate connected to the top of the arc-shaped limiting plate.

[0013] Preferably, a second limiting plate is connected to the side of the flip plate away from the receiving rack.

[0014] Preferably, a roller is rotatably connected to the flip plate, the roller protrudes upward from the flip plate, and several rollers are evenly arranged. Several sets of buffer components are evenly arranged, and the rollers and the sets of buffer components are alternately arranged.

[0015] The beneficial effects of this utility model are as follows:

[0016] The automatic receiving mechanism supports the pipe through the middle of the flip plate. The first cylinder drives the telescopic stop to rise and protrude from the top surface of the flip plate. When the flip plate flips from a horizontal state to an inclined state, the telescopic stop supports the lower side of the pipe. When the second cylinder drives the slide to move downward along the slide groove, the pipe follows the telescopic stop and slides downward. When the pipe slides to the end of the flip plate, the first cylinder drives the telescopic stop to retract, thereby shortening the distance of the pipe falling freely onto the receiving rack. This prevents the pipe from falling too fast and causing a large impact, preventing damage to the pipe and preventing the pipe from falling out of the receiving rack, thus improving the reliability of pipe feeding.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1-9. This utility model provides a technical solution: an automatic receiving mechanism, including a flip plate 1 and a receiving rack 2 disposed on one side of the flip plate 1, and also includes a buffer assembly 3. The buffer assembly 3 includes a first cylinder 301, a second cylinder 302, a slide block 303 and a telescopic stop bar 304. The flip plate 1 is provided with a strip-shaped through groove 4, and a sliding groove 25 is provided below the strip-shaped through groove 4. The slide block 303 is slidably disposed in the sliding groove 25, and its lower side is fixedly connected to the first cylinder 301. The output end of the first cylinder 301 is fixedly connected to the telescopic stop bar 304. The middle part of the slide block 303 is provided with a through hole 305, and the telescopic stop bar 304 is disposed in the through hole 305. The second cylinder 302 is fixedly connected to the side of the flip plate 1 away from the receiving rack 2, and its output end is fixedly connected to the side of the slide block 303 away from the receiving rack 2.

[0029] After the pipe is cut, it is supported by a horizontally positioned flip plate 1. A first cylinder 301 drives a telescopic stop bar 304 to rise and protrude from the top surface of the flip plate 1. Then, a second cylinder 302 drives a slide block 303 to move horizontally along a slide groove 25, thereby causing the telescopic stop bar 304 to move horizontally and abut against one side of the pipe. The flip plate 1 then flips from a horizontal position to an inclined position. At this time, the telescopic stop bar 304 supports the inclined lower side of the pipe. Then, the second cylinder 302... The drive slide 303 moves downward along the slide groove 25 at an angle, and the pipe slides downward at an angle following the telescopic stop bar 304. When the pipe slides to the end of the flip plate 1, the first cylinder 301 drives the telescopic stop bar 304 to retract. At this time, the pipe falls out of the flip plate 1 and undergoes free fall, which shortens the distance of the pipe falling to the receiving rack 2, prevents the pipe from falling too fast and causing a large impact collision with the receiving rack 2, prevents damage to the pipe and prevents the pipe from falling out of the receiving rack 2, and improves the reliability of pipe feeding.

[0030] In order to facilitate the automatic flipping of the flipping plate 1, in this embodiment, preferably, a third cylinder 5 and a support plate 6 are hinged to the lower side of the flipping plate 1. The support plate 6 is located on the side of the third cylinder 5 away from the receiving rack 2. The purpose is to drive the flipping plate 1 to flip downward on the side close to the receiving rack 2 through the third cylinder 5, thereby making the flipping plate 1 tilted.

[0031] To facilitate the lifting and lowering of the rotating plate 1, in this embodiment, preferably, a first support 7 is fixedly connected to the lower side of the support plate 6, and a rack 8 is connected to one side of the support plate 6. The bottom of the third cylinder 5 is hinged to the first support 7. A gear 9 is meshed with the rack 8. A reduction gearbox 10 is driven by the gear 9. A motor 11 is driven by the reduction gearbox 10. A second support 12 is fixedly connected to the reduction gearbox 10. A C-shaped slider 13 is fixedly connected to the second support 12. A slide rail 14 is connected to one side of the support plate 6. The C-shaped slider 13 is slidably connected to the slide rail 14.

[0032] The purpose is that the motor 11 drives the gear 9 to rotate through the reduction gearbox 10, and then drives the support plate 6, the first support 7, the third cylinder 5 and the tilting plate 1 to lift and lower as a whole through the rack 8. At the same time, the slide rail 14 slides and lifts along the C-shaped slider 13, improving the accuracy and stability of the lifting stroke. After the tilting plate 1 receives the pipe and before the tilting plate 1 is driven to tilt, the tilting plate 1 can be driven to drop a certain height first, further shortening the distance of the pipe falling freely onto the receiving rack 2.

[0033] In order to facilitate the horizontal movement of the rotating plate 1, in this embodiment, preferably, a translation frame 15 is connected to the lower side of the second support 12, a base 16 is slidably connected to the lower side of the translation frame 15, and a push-pull plate 17 is connected to the side of the base 16 away from the receiving frame 2. A fourth cylinder 18 is connected to the side of the base 16 away from the receiving frame 2, and the output end of the fourth cylinder 18 is fixedly connected to the push-pull plate 17.

[0034] The purpose is to drive the fourth cylinder 18 to move the translation frame 15 horizontally relative to the base 16 through the push-pull plate 17, thereby driving the second support 12, the C-shaped slider 13, the slide rail 14, the support plate 6, the first support 7, the third cylinder 5 and the flip plate 1 to move horizontally as a whole. This allows the flip plate 1 to be moved and adjusted so that it is aligned with the receiving rack 2, preventing the flip plate 1 from being misaligned with the receiving rack 2 and causing the pipe to fail to fall accurately from the flip plate 1 onto the receiving rack 2.

[0035] For convenience, in this embodiment, preferably, two guide grooves 19 are symmetrically provided on both sides of the slide groove 25, and two guide blocks 306 are symmetrically connected on both sides of the slide block 303. The two guide blocks 306 are slidably disposed in the two guide grooves 19 respectively.

[0036] In order to prevent scratching the surface of the pipe, in this embodiment, preferably, a rubber sleeve 307 is fitted on the outer side of the telescopic stop bar 304. The purpose is to make the telescopic stop bar 304 contact the pipe through the rubber sleeve 307 to prevent scratching the surface of the pipe.

[0037] To prevent the pipe from falling out of the receiving rack 2, in this embodiment, preferably, one side of the receiving rack 2 is connected to an inclined limiting plate 20, and the other side is connected to an arc-shaped limiting plate 21. The top of the arc-shaped limiting plate 21 is connected to a first limiting plate 22. The purpose is to make the pipe roll along the inclined surface of the inclined limiting plate 20 and then roll towards the arc-shaped limiting plate 21 when the pipe falls from the flip plate 1 to the inclined limiting plate 20. Then, through the clamping and frictional resistance of the arc surface of the arc-shaped limiting plate 21, the kinetic energy of the pipe is gradually consumed, and finally a stable stop is achieved. The first limiting plate 22 prevents the pipe from rushing out of the arc-shaped limiting plate 21.

[0038] In order to prevent the pipe from falling out from the side of the flip plate 1 away from the receiving rack 2, in this embodiment, preferably, a second limiting plate 23 is connected to the side of the flip plate 1 away from the receiving rack 2.

[0039] To facilitate the smooth movement of the pipe onto the flip plate 1 and prevent scratching, in this embodiment, preferably, a roller 24 is rotatably connected to the flip plate 1. The roller 24 protrudes upward from the flip plate 1, and several rollers 24 are evenly arranged. Several sets of buffer components 3 are evenly arranged. The rollers 24 and the buffer components 3 are alternately arranged. The purpose is that before the pipe is cut, when the pipe moves from one end of the flip plate 1 to the other end, the rollers 24 support the pipe and roll along with the pipe, improving the smoothness of the pipe movement and preventing scratching.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
