Description

Technical Field

[0001] The invention relates to the technical field of material receiving equipment, and in particular to a material receiving device. Background Art

[0002] Laser cutting has the characteristics of high flexibility, fast cutting speed, high production efficiency and short product production cycle, so it is widely used in the manufacturing industry, such as using laser to cut pipes or profiles.

[0003] Existing laser tube cutting machines are generally equipped with a material receiving device to assist in material unloading, which can greatly reduce labor intensity and improve material unloading safety. For example, the Chinese patent with publication number CN215145859U discloses a material rack module, in which the loading and unloading parts of the material rack module adopt the same structure, and the workpiece after cutting is transferred to the storage station of the storage mechanism through the transverse material transport mechanism. The transverse material transport mechanism includes a lifting cylinder and a lifting slide plate arranged on the output end of the lifting cylinder.

DETAILED DESCRIPTION

[0030] The present invention provides a material receiving device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0031] See also Figure 1-Figure 5The present invention provides a material receiving device, comprising a plurality of material receiving modules 100 arranged at intervals and a plurality of material discharge racks 200 arranged at intervals behind the material receiving modules 100, each material receiving module 100 comprises a material receiving base frame 1, a fixed plate 2 arranged on the material receiving base frame 1, a first section movable plate 3 arranged on the fixed plate 2 and capable of being raised and lowered, a second section movable plate 4 arranged on the first section movable plate 3 and capable of being raised and lowered, a first section material receiving component 5 for driving the first section movable plate 3 to be raised and lowered, and a second section material receiving component 6 for driving the second section movable plate 4 to be raised and lowered following the first section movable plate 3 to be raised and lowered, a material receiving plate 7 is hingedly connected to the top of the second section movable plate 4, and a material receiving drive component 8 is arranged on the second section movable plate 4 for driving the material receiving plate 7 to support pipe fittings when it is horizontal or to guide the pipe fittings to the material discharge rack 200 located behind the material receiving base frame 100 when it is tilted backward.

[0032] In actual application, the material receiving device is located behind the rear section of the pipe cutting machine (i.e., in front of the material receiving device of the pipe cutting machine), the front section of the pipe cutting machine is used for feeding the pipe fittings, and the middle section of the pipe cutting machine is used for cutting the pipe fittings. The two ends and the middle part of the pipe fittings are fixed by a chuck arranged on the pipe cutting machine, and the chuck can reciprocate along the length direction of the pipe cutting machine.

[0033] See also Figure 1 In this embodiment, the material receiving modules 100 are arranged to be five at intervals, and the material unloading racks 200 are arranged to be seven at intervals. The five groups of material receiving modules 100 are electrically connected to the control center, and can be operated independently or in multiple groups synchronously, and can be used to receive materials for pipes of different lengths such as three meters, six meters, nine meters, and twelve meters. When the pipe is twelve meters, the weight of a single pipe can reach 1500kg; and the material receiving device is suitable for square pipes, rectangular pipes, H-shaped steels, channel steels, angle irons, small-diameter round pipes, medium-diameter round pipes, large-diameter round pipes and other profiles, making the material receiving device more versatile and adaptable.

[0034] See also Figure 1 and Figure 2 The front side of each group of material receiving modules 100 is connected to the rear side of the pipe cutting machine for fixing the material receiving modules 100. Each unloading rack 200 is provided with four bolt holes 203 for connecting and positioning with the ground through bolts. Each unloading rack 200 is fixed separately, that is, it is not connected to the material receiving module 100. The unloading rack 200 can be placed at any position according to the length of the receiving pipe fittings, and the impact force of the pipe fittings on the unloading rack 200 when unloading large or heavy pipe fittings will not be transmitted to the material receiving module 100, that is, the position of the material receiving module 100 will not change and will not affect the precision parts on the material receiving module 100.

[0035] See also Figure 5 and Figure 7When the pipe is cut, under the action of the first-stage receiving component 5, the first-stage movable plate 3 is driven to rise. At the same time, under the action of the second-stage receiving component 6, the second-stage movable plate 4 rises along with the rise of the first-stage movable plate 3, so that the second-stage movable plate 4 realizes a two-stage rising support stroke. When the second-stage movable plate 4 rises, the receiving drive component 8 and the receiving plate 7 arranged thereon are driven to rise synchronously. At this time, under the action of the receiving drive component 8, the receiving plate 7 is in a horizontal state, and the receiving plate 7 abuts against the bottom end of the pipe being cut. When the pipes to be cut are rectangular pipes, square pipes, H-shaped steel, channel steel, angle iron and other profiles, the distance from the lowest point of the profile to the ground changes at any time due to the rotation of the profile driven by the chuck. Therefore, under the joint action of the first-stage receiving assembly 5 and the second-stage receiving assembly 6, the first-stage movable plate 3 and the second-stage movable plate 4 follow the change in the height of the pipe from the ground and change their lifting height accordingly, so that the receiving plate 7 can support the pipes accordingly, which can effectively prevent large and heavy pipes from shaking during rotation or movement, thereby reducing the cutting accuracy. Please refer to Figure 1-Figure 3 and Fig. 9 After the cutting is completed, the chuck releases the clamping of the pipe fitting, and the pipe fitting is supported on the receiving plate 7. While the first-stage receiving assembly 5 drives the first-stage movable plate 3 to descend, the second-stage receiving assembly 6 drives the second-stage movable plate 4 to descend until the heights of the fixed plate 2, the first-stage movable plate 3 and the second-stage movable plate 4 are basically the same; then, under the action of the receiving drive assembly 8, the rear end of the receiving plate 7 is tilted downward, so that the round tube rolls to the unloading rack 200 located behind the receiving module 100 or the profile slides to the unloading rack 200 located behind the receiving module 100 under the guidance of the inclined receiving plate 7.

[0036] The material receiving device is suitable for the unloading of pipes of different lengths by setting up multiple material receiving modules 100 and multiple material unloading racks 200; a material receiving base frame 1 is provided for installing a fixed plate 2, a first-stage material receiving component 5 is driven to rise or fall on a first-stage movable plate 3, a second-stage material receiving component 6 is driven to rise when the second-stage movable plate 4 rises or falls when the first-stage movable plate 3 rises, and a material receiving drive component 8 is provided to make the material receiving plate 7 horizontal or inclined, so that the material receiving device has the function of supporting the pipes up and down, and realizes the support stroke with the minimum compression ratio of the two-stage rise or fall, and can realize a larger moving stroke, adapt to the material receiving height requirements of the pipe cutting machine, and is conducive to the rational use of space.

[0037] See also Figure 5 , Figure 7 and Figure 8Further, the two-stage material receiving assembly 6 includes a first material receiving positioning block 61 arranged on the front side of the fixed plate 2, a second material receiving positioning block 62 arranged on the front side of the second-stage movable plate 4, two material receiving bearing seats 63 arranged on the upper side walls of the first-stage movable plate 3, a rotating shaft 64 rotatably arranged between the two material receiving bearing seats 63, a material receiving sprocket 65 arranged on both ends of the rotating shaft 64, and a material receiving chain 66 connected to the first material receiving positioning block 61 and the second material receiving positioning block 62 at both ends, and the middle position of the material receiving chain 66 is meshed with the corresponding material receiving sprocket 65 for transmission. Two material receiving sprockets 65 and two material receiving chains 66 are arranged to ensure force balance, and one rotating shaft 64 drives the two material receiving sprockets 65 to rotate coaxially.

[0038] Specifically, the lower part of the second-stage movable plate 4 is provided with an N-shaped groove for avoiding the first-stage receiving component 5. Figure 5 , Figure 7 and Figure 8 The two ends of the material receiving chain 66 are respectively fixed on the first material receiving positioning block 61 and the second material receiving positioning block 62, that is, the two ends of the material receiving chain 66 are equivalent to being connected to the front side of the fixed plate 2 and the second movable plate 4 respectively. When the first material receiving component 5 rotates forward to drive the first movable plate 3 and the material receiving bearing seat 63, rotating shaft 64, and material receiving sprocket 65 arranged on the first movable plate 3 to rise synchronously, under the driving action of the material receiving sprocket 65, the material receiving chain 66 with one end connected to the front side of the fixed plate 2 is subjected to force to pull the second movable plate 4 to rise synchronously, realizing the supporting stroke of the two-stage rise. Please refer to Fig. 9 On the contrary, when the first section receiving assembly 5 rotates in the opposite direction to drive the first section movable plate 3 to descend, the receiving sprocket wheel 65 is always engaged with the receiving chain 66, and the second section movable plate 4 is synchronously descended under the gravity of the second section movable plate 4 and the traction of the receiving chain 66 until the heights of the second section movable plate 4, the first section movable plate 3 and the highest position of the fixed plate 2 are basically the same. The above structure is simple and ingeniously designed. By adopting the receiving chain 66 and the receiving sprocket wheel 65, the second section movable plate 4 can be pulled up or down following the first section movable plate 3, the manufacturing cost is low, and the effect of achieving a two-stage lifting stroke is remarkable.

[0039] See also Figure 7Furthermore, a tension adjustment block 67 is provided on the front side of the fixed plate 2, and the tension adjustment block 67 is arranged above the first material receiving and positioning block 61; the first material receiving and positioning block 61 is provided with a first adjustment waist-shaped hole 611 extending along its height direction, and the fixed plate 2 is provided with a first threaded hole corresponding to the first adjustment waist-shaped hole 611, and the first adjustment waist-shaped hole 611 and the first threaded hole are provided with the same first locking screw (not shown in the figure); the tension adjustment block 67 is provided with a second threaded hole 671 passing through the upper and lower side walls thereof, and the first limit screw 68 is threadedly connected to the second threaded hole 671, and the end of the first limit screw 68 abuts against the upper surface of the first material receiving and positioning block 61.

[0040] During installation, the first material receiving positioning block 61 is first fixed to the front side of the fixed plate 2 by the first locking screw, and then the tension adjustment block 67 is fixed to the front side of the fixed plate 2 by the screw. When the tension of the material receiving chain 66 needs to be adjusted, since the second material receiving positioning block 62 is fixed on the second-stage movable plate 4, the tension of the material receiving chain 66 can be finely adjusted by adjusting the position of the first material receiving positioning block 61 relative to the fixed plate 2. The specific adjustment steps are as follows: when the material receiving chain 66 needs to be tightened, first loosen the first locking screw so that the first material receiving positioning block 61 can move upward under the guidance of the first adjusting waist-shaped hole 611 (because due to the self-weight of the two-stage movable plate 4, one end of the material receiving chain 66 connected to the second material receiving positioning block 62 will pull the other end of the material receiving chain 66 connected to the first material receiving positioning block 61); then screw the first limiting screw 68 into the second threaded hole 671 from top to bottom. In the process of screwing in the first limiting screw 68, the end of the first limiting screw 68 pushes the first material receiving positioning block 61 downward, and then measures the distance from the lower surface of the tension adjustment block 67 to the upper surface of the first material receiving positioning block 61 by a measuring instrument such as a caliper. After reaching the preset distance, finally lock the first material receiving positioning block 61 on the fixed plate 2 by the first locking screw. Conversely, when the material receiving chain 66 needs to be loosened, the first locking screw is also loosened first, and then the first limiting screw 68 is gradually screwed out of the second threaded hole 671, and the distance between the tension adjustment block 67 and the first material receiving positioning block 61 is measured, and then the first locking screw is re-locked. Through the above settings, the distance between the tension adjustment block 67 and the first material receiving positioning block 61 can be intuitively known through the distance meter, so as to achieve accurate adjustment of the tension of the material receiving chain 66.

[0041] See also Figure 7 and Figure 8Furthermore, a two-stage material receiving slider 42 is provided on the rear side of the one-stage movable plate 3, and a two-stage material receiving slide rail 41 extending along its height direction is provided on the front side of the two-stage movable plate 4, and the two-stage material receiving slider 42 is slidably provided on the two-stage material receiving slide rail 41. The two-stage material receiving slide rail 41 is provided with two, and each of the two-stage material receiving slide rail 41 is provided with more than one two-stage material receiving slider 42. When installing the two-stage material receiving slide rail 41, any one of the two-stage material receiving slide rails 41 is taken as the main guide rail, and the other is taken as the auxiliary guide rail. The side reference of the main guide rail rests on the slide rail installation surface of the two-stage movable plate 4, and then the collimator is used to detect the flatness and straightness of the entire main guide rail, and the accuracy is corrected to make the straightness accuracy corrected to ≤0.02mm / m, and then the auxiliary guide rail is installed and the dial indicator is used to detect the parallelism of the main guide rail and the auxiliary guide rail, and then the auxiliary guide rail is corrected, and the parallelism of the main guide rail and the auxiliary guide rail is ≤0.03mm. By providing the two-stage receiving slide block 42 and the two-stage receiving rail 41, the two-stage movable plate 4 can be smoothly raised or lowered under the guidance of the two-stage receiving rail 41, thereby improving the stability of the receiving plate 7 provided thereon, thereby improving the supporting effect on the pipe fittings.

[0042] See also Figure 7 and Figure 8 Further, the upper part of the front side of the two-stage movable plate 4 is provided with a first-stage two-stage limit seat 43 and a first-stage two-stage anti-collision block 44 arranged below the first-stage two-stage limit seat 43, and the first-stage two-stage anti-collision block 44 is arranged on the rear side of the one-stage movable plate 3; the lower part of the front side of the two-stage movable plate 4 is also provided with a second-stage two-stage anti-collision block 45 and a second-stage two-stage limit seat 46 arranged above the second-stage two-stage anti-collision block 45, and the second-stage two-stage limit seat 46 is arranged on the rear side of the one-stage movable plate 3. Under normal circumstances, the first-stage two-stage limit seat 43 will not contact the first-stage two-stage anti-collision block 44, and similarly, the second-stage two-stage anti-collision block 45 will not contact the second-stage two-stage limit seat 46, that is, the distance between the first-stage two-stage limit seat 43 and the second-stage two-stage limit seat 46 is greater than the moving stroke of the two-stage movable plate 4. The above-mentioned arrangement is used to prevent the one-stage material receiving component 5 from continuously running, and plays a role in limiting the moving stroke of the two-stage movable plate 4.

[0043] See also Figure 5Furthermore, the one-stage material receiving assembly 5 includes a one-stage material receiving drive motor 51, a material receiving transmission gear 9 (not visible in the figure) that is transmission-connected to the output end of the one-stage material receiving drive motor 51, and a material receiving transmission rack 52 that is arranged on the rear side surface of the fixed plate 2 and extends along its height direction, and the material receiving transmission gear is meshed with the material receiving transmission rack 52. When in use, when the one-stage material receiving drive motor 51 rotates forward, it drives the material receiving transmission gear to rotate forward, and under the guidance of the material receiving transmission rack 52, a section of movable plate 3 connected to the one-stage material receiving drive motor 51 is raised. On the contrary, when the one-stage material receiving drive motor 51 rotates reversely, it drives the material receiving transmission gear to rotate reversely, so that a section of movable plate 3 is lowered. The above structure has high transmission efficiency and high transmission accuracy.

[0044] Specifically, the one-stage material receiving drive motor 51 is a servo motor, which has a brake function, which can prevent the large and heavy pipes and the second-stage movable plate 4 from falling due to a sudden power failure of the one-stage material receiving drive motor 51 when cutting, supporting or receiving the pipes, causing safety hazards.

[0045] See also Figure 3 and Figure 4 Further, the upper part of the receiving frame 1 is provided with a first position sensor 11, and the lower part of the side wall of the first movable plate 3 is provided with a first sensing sheet 31 for sensing the first position sensor 11; the lower part of the receiving frame 1 is provided with a second position sensor 12, and the lower part of the side wall of the second movable plate 4 is provided with a second sensing sheet 47 for sensing the first position sensor 11 and the second position sensor 12. The first position sensor 11 and the second position sensor 12 are electrically connected to the control center respectively, and the first receiving drive motor 51 is electrically connected to the control center. When the first sensing sheet 31 on the first movable plate 3 rises to the side of the first position sensor 11, the second movable plate 4 rises to the highest height, the first position sensor 11 transmits the arrival signal to the control center, and the control center transmits the stop signal to the first material receiving drive motor 51 to stop it; when the second movable plate 4 drives the second sensing sheet 47 thereon to descend to the side of the second position sensor 12, the heights of the second movable plate 4 and the first movable plate 3 are the lowest, the second position sensor 12 transmits the arrival signal to the control center, and the control center transmits the stop signal to the first material receiving drive motor 51 to stop it. Through the above settings, precise arrival is achieved. The first position sensor 11 and the second position sensor 12 only show the mounting frame for installing the first position sensor 11 and the second position sensor 12. The first position sensor 11 and the second position sensor 12 are conventional products that can be purchased directly on the market.

[0052] See also Figure 4Furthermore, a material receiving height adjustment plate 48 is provided on the rear side surface of the second-stage movable plate 4, and the cylinder body of the material receiving cylinder is provided on the rear side surface of the material receiving height adjustment plate 48; the material receiving height adjustment plate 48 is provided with a third adjusting waist-shaped hole (not shown in the figure) extending along its height direction, and the second-stage movable plate 4 is provided with a sixth threaded hole (not shown in the figure) corresponding to the third adjusting waist-shaped hole, and the third adjusting waist-shaped hole and the sixth threaded hole are provided with the same third locking screw; a material receiving height adjustment block 49 is provided above the material receiving height adjustment plate, and the material receiving height adjustment block 49 is provided with a second through hole running through the upper and lower side walls thereof, and the material receiving height adjustment plate 48 is provided with a seventh threaded hole corresponding to the second through hole, and a third limiting screw is provided in the second through hole, and the end of the third limiting screw is threadedly connected with the seventh threaded hole.

[0053] See also Figure 2 and Fig.10 Further, two opposite material head bearing seats 91 (i.e., material receiving module No. 1 100) are arranged on the left side of the lower surface of the material receiving plate 7 at the far left end, and a material head rotating shaft 92 is arranged between the two material head bearing seats 91, and a material head folding plate 9 is arranged around the outer periphery of the material head rotating shaft 92, and the height of the material head folding plate 9 is flush with the height of the material receiving plate 7, and a material head cylinder 93 is also arranged on the lower surface of the material receiving plate 7, and the output end of the material head cylinder 93 is connected to the lower surface of the material head folding plate 9; a material head hopper 94 is arranged below the material head folding plate 9, and a short material hopper 73 is arranged behind the material receiving plate 7. That is, the material receiving module 100 at the far left end is used to distinguish between material heads and short material finished products. In this embodiment, there may be short materials and material heads after the pipe fittings are cut, and the cutting control center can automatically determine and distinguish whether there are material heads that need to be unloaded. The short material and the material head are synchronously unloaded onto the material receiving plate 7 and the material head folding plate 9 (at this time, the output end of the material head cylinder 93 is extended, and the output end of the material receiving cylinder is extended, so that the material receiving plate 7 and the material head folding plate 9 are both in a horizontal state), and then the first-stage movable plate 3 and the second-stage movable plate 4 drive the material receiving plate 7 and the material head folding plate 9 to descend to the lowest position, and then the output end of the material head cylinder 93 is changed from the extended state to the contracted state. In the process of contraction, the material head folding plate 9 is driven to fold downward 90° under the guidance of the material head rotating shaft 92, so that the material head freely falls into the material head hopper 94 located below the material head folding plate 9. After the unloading of the material head is completed, the output end of the material receiving cylinder is then contracted, so that the material receiving plate 7 is tilted downward, so that the short material is unloaded into the short material hopper 73.

[0054] See also Figure 2 and Fig.10Furthermore, the material head folding plate 9 is provided with a laser air-avoiding opening 95 extending along the width direction thereof. Since the No. 1 material receiving module 100 is located below the laser cutting head, the laser air-avoiding opening 95 can effectively prevent the material head folding plate from being cut during high-energy laser cutting.

[0055] See also Figure 2 Furthermore, both ends of the material discharging rack 200 are provided with stopper columns 201, and the upper surface of the material discharging rack 200 is provided with a buffer rubber pad 202. The setting of the stopper columns 201 is used to limit the position of the pipe fittings, prevent the pipe fittings from rolling and falling, and ensure safety performance. Since the pipe fittings or profiles on the tilted receiving plate 7 fall onto the material discharging rack 200 under the action of gravity, the impact force of large and heavy pipes on the material discharging rack 200 is relatively large, and the buffer rubber pad 202 is provided to safely buffer the material discharging and protect the surface of the pipe fittings or profiles to prevent hard collision with the material discharging rack 200.
