Description

Technical Field

[0001] The utility model relates to a pipe feeding device, and more specifically to a full-automatic loading rack for a laser pipe cutting machine. Background Art

[0002] At present, there are three ways to feed pipes for laser pipe cutting machines: manual feeding, semi-automatic feeding, and full-automatic feeding. When there are a large number of pipes of the same specification to be cut, full-automatic feeding is the most suitable. Full-automatic feeding has the advantages of high feeding efficiency, few single-machine operators, and low labor intensity of operators.

[0003] There are various styles of existing full-automatic loading racks for laser pipe cutting machines on the market. Some can only be used for full-automatic feeding of round pipes, some can only be used for full-automatic feeding of square pipes. The full-automatic loading racks that can be fully applied to round pipes, square pipes, and rectangular pipes have a relatively complex structure, and there are few mature and reliable models. Moreover, they all have several defects and limitations:

[0004] First, the coverage range of the cross-sectional dimensions of the applicable pipes is small, and it is only suitable for pipes with small cross-sectional dimensions.

[0005] Second, there are safety hazards. For the most mainstream full-automatic loading racks on the market, in the primary material distribution, 3 - 4 slings are used to support a whole bundle of pipes weighing about 2 - 3 tons. The motor shortens the slings through a worm and worm gear reducer, a coupling, a 5-meter-long shaft, and a reel, causing the 2 - 3-ton bundle of pipes to move up and down frequently for primary material distribution. Each up and down movement does not necessarily ensure that one pipe is effectively distributed. The 2 - 3-ton bundle of pipes needs to move up and down 1 - 3 times, or even more times, to ensure one effective material distribution. Therefore, dozens of 2 - 3-ton pipes roll, slide, and rub frequently on the slings, intensifying the wear of the slings, which poses a serious safety hazard. If daily safety inspections are not in place and the slings are not replaced in a timely manner, if one sling suddenly breaks during work, the single sling load of the remaining slings suddenly increases. Since several slings are almost worn equally and at the same time, the remaining slings are likely to break in a chain reaction due to the sudden increase in load. The 2 - 3-ton pipes lose effective balanced support and slide to one side, causing serious personal injuries to the operators nearby. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a full-automatic loading rack for a laser pipe cutting machine, which abandons the primary material distribution method using slings and adopts a V-shaped groove + lifting cylinder structure for primary material distribution, with better safety and eliminating the safety hazard of sling breakage in the primary material distribution method using slings.

The terms used in the description of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figures 1 to 5, a fully automatic loading rack for a laser pipe cutting machine provided by the present utility model, which is composed of two unit loading racks 10 with the same structure. The pipes are supported by at least one of the unit loading racks 10. In some embodiments, it can be composed of three unit loading racks 10, that is, the fully automatic loading rack of the laser pipe cutting machine of the present utility model is composed of at least two unit loading racks 10.

[0024] In this embodiment, Figure 1 As shown, the number of the unit loading racks 10 is three, which respectively support the head and tail ends and the middle part of the pipe A, and jointly lift and transport the pipe.

[0025] In this embodiment, the unit loading rack 10 is provided with a first-level V-shaped groove 11, a second-level V-shaped groove 12, and a third-level V-shaped groove 13 for supporting the pipe A and decreasing in height. The top of the first-level V-shaped groove 11 is provided with a discharge ramp 14. The outer sides of the first-level V-shaped groove 11, the second-level V-shaped groove 12, and the third-level V-shaped groove 13 are all provided with a pipe lifting mechanism 17 for lifting the pipe to the upper level. The pipe A first passes through the third-level V-shaped groove 13, and the pipe A is lifted to the second-level V-shaped groove 12 by the pipe lifting mechanism 17, and then is lifted into the first-level V-shaped groove 11 again through the pipe lifting rack of the second-level V-shaped groove.

[0026] In this embodiment, a detection ferry release mechanism 15 is arranged outside the discharge ramp 14. The detection ferry release mechanism 15 includes a first guide rail pair 151 installed on the side of the discharge ramp 14, a slow-down cylinder 152 fixed on the discharge ramp 14 for pushing the slide plate of the first guide rail pair 151 to move, a material blocking and release cylinder 153 fixed on the slide plate of the first guide rail pair 151, a reverse push cylinder 154 fixed on the cylinder shaft of the material blocking and release cylinder 153, and a material blocking plate 155 fixed on the reverse push cylinder 154. The slow-down cylinder 152 is used to push the slide plate of the first guide rail pair 151 to move in the descending or ascending direction of the discharge ramp 14, and the material blocking and release cylinder 153 is used to push the reverse push cylinder 154 to lift and lower, so as to push the material blocking plate 155 to extend above and below the discharge ramp 14, so as to achieve the effect of blocking the material and pushing the pipe on the discharge ramp 14 through the reverse push cylinder 154. When the pipes in the first-level V-shaped groove are emptied, the pipe lifting cylinder mechanism in the second-level V-shaped groove will lift a part of the reserved pipes in the second-level V-shaped groove and send them into the first-level V-shaped groove for a one-time replenishment, and several pipes are replenished each time.

[0027] When the pipes in the second-level V-shaped groove are emptied, the pipe lifting cylinder mechanism in the third-level V-shaped groove will lift a part of the reserved pipes in the third-level V-shaped groove and send them into the second-level V-shaped groove for a one-time replenishment, and several pipes are replenished each time.

[0028] Each level of V-shaped groove is equipped with a pipe sensor, which can detect the presence or absence of pipes in the V-shaped groove.

[0029] There is only one correct case where the pipe is fed into the discharge ramp, and it can be prepared for slow descent and release. In all other cases, it is not a correct material separation, and the pipe must be pushed back to the first-level V-shaped groove. The only correct material separation is: among the three detection sensors in the V-shaped groove, only the middle detection sensor can detect the pipe, and the two side detection sensors cannot detect the pipe.

[0030] If it is a correct material separation, the reverse push cylinder does not act, waits for the signal to prepare for slow descent and release. After there is no waiting pipe in the waiting area and all the cylinders in the waiting area are reset, the slow descent cylinder descends along the direction of the discharge ramp, ferries the correctly separated pipe to the lower dead point of the slow descent cylinder, then the material blocking and releasing cylinder retracts to release the pipe. The released pipe slides along the remaining ramp slide under its own gravity to the waiting area and stops when it hits the waiting area stop bar. The three cylinders of the detection ferry release mechanism are all reset, waiting for the separated pipe to enter the detection V-shaped groove again.

[0031] If it is an incorrect material separation, the reverse push cylinder acts, pushes all the pipes in the detection V-shaped groove back to the first-level V-shaped groove, and then resets. Then, the first-level lifting cylinder mechanism of the first-level V-shaped groove acts again to lift the pipes for primary material separation again.

[0032] In this embodiment, a feeding-in-place mechanism 16 is provided outside the end of the discharge ramp 14. The feeding-in-place mechanism 16 includes a second guide pair 161, a feeding plate 162 mounted on the slide plate of the second guide pair 161, a feeding cylinder 163 for pushing the feeding plate 162 to move, a swing stop bar 164 whose bottom end is rotatably mounted at the end of the feeding plate 162, and a swing cylinder 165 mounted on the feeding plate 162 and movably connected to the top end of the swing stop bar 164. The pipe falls onto the feeding plate through the discharge ramp 14, and the feeding plate horizontally pushes out the fallen pipe.

[0033] In this embodiment, the pipe lifting mechanism 17 includes a third guide pair 171, a lifting plate 172 for fixing the movement of the slide plate of the third guide pair 171, and a lifting cylinder 173 for pushing the lifting plate 172 to lift and lower.

[0034] In this embodiment, the unit loading rack 10 includes a bottom beam 101, and a first inclined rod 102, a second inclined rod 103, a third inclined rod 104, a fourth inclined rod 105, and a fifth inclined rod 106 that are successively fixed on the bottom beam 101 from the rear end to the front end. The first inclined rod 102 and the second inclined rod 103 define the three-stage V-shaped groove. The top of the second inclined rod 102 and the third inclined rod 103 define the two-stage V-shaped groove. The top of the third inclined rod 103 and the fourth inclined rod 105 define the one-stage V-shaped groove. The top surface of the fifth inclined rod 106 defines the discharge ramp.

[0035] It is worth mentioning that the first guide rail pair, the second guide rail pair, and the third guide rail pair are conventional fittings in the art, and they include a guide rail and a slide plate slidably mounted on the guide rail.

[0036] In order to improve safety performance and prevent the pipe from sliding, anti-slip nylon strips B are provided on the groove walls of the one-stage V-shaped groove, the two-stage V-shaped groove, the three-stage V-shaped groove, and the discharge ramp.

[0037] The utility model adopts an open structure. There is no gantry or other obstacles above the unit loading rack, which facilitates the operation of loading the whole bundle of pipes. It can be loaded with a whole bundle by overhead crane or forklift. The utility model is applicable to the full-automatic loading of round pipes, square pipes, and rectangular pipes.

[0038] The utility model has the following advantages:

[0039] Advantage 1: Eliminate potential safety hazards. The utility model abandons the primary feeding method with sling, and adopts the V-shaped groove + lifting cylinder structure for primary feeding, which has better safety and eliminates the potential safety hazard of sling breakage in the primary feeding method with sling.

[0040] Advantage 2: Energy saving and consumption reduction. The primary feeding three-stage cylinder lifting structure uses the cylinder as the power itself, does not require a high-power motor, greatly reduces the power and energy consumption of primary feeding. In addition, only the one-stage lifting cylinder mechanism of the one-stage V-shaped groove participates in primary feeding, and the two-stage and three-stage lifting cylinder mechanisms only intermittently act to replenish materials to the upper-stage V-shaped groove when there is no material in the upper-stage V-shaped groove, which further reduces the system energy consumption.

[0041] Advantage 3: Detect the V-shaped groove through three sensors to detect and judge whether the pipe sent by primary feeding is correct, whether to release it or push it back in reverse. In this way, when changing the pipe specification, only the positions of the three sensors need to be adjusted to sense and detect the new pipe, and the adjustment is very convenient and fast.

[0042] Advantage 4: The bottom dead point of the slow-down cylinder is controlled by the cylinder magnetic switch, which is convenient for adjusting the bottom dead point position. The appropriate release height can be selected according to the weight, cross-sectional shape, surface smoothness, sliding speed, and potential energy impact force of a single pipe, so that the released pipe can rely on its own gravity to slide smoothly to the position of the barrier rod in the standby area without causing too much impact on the barrier rod and causing damage.

[0043] Advantage 5: The utility model adopts a modular structure, each unit rack is identical and independent, which is convenient for flexible combination and stacking when loading into vehicles and cabinets, and occupies less transportation space.

[0044] Advantage 6: The utility model adopts an open structure, without a rack, and the top of the rack is completely open, which is very convenient for loading the whole bundle of pipes into the V-groove silo with a crane or a forklift. Also, because there is no hard connection between the unit racks (except for the electrical cable duct near the front ground), the personnel passage is unobstructed, which is very friendly for equipment maintenance, repair, and additional manual loading of special pipes.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
