Description

Technical Field

[0001] This invention relates to the field of automated processing technology, and in particular to an automated production line for arched supports. Background Technology

[0002] Section steel is a type of strip steel with a specific cross-sectional shape and size. It is one of the four major categories of steel (plates, pipes, sections, and wires). Based on the cross-sectional shape, section steel is divided into simple section steel and complex section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channel steel, rails, window frame steel, bent section steel, etc.

[0003] The current production process of arched steel supports cannot achieve systematic continuous automated production. Continuous feeding is not possible, and many processes still require manual assistance. The level of automation is low, resulting in high labor intensity for workers and low production efficiency, which cannot meet the market demand for large-scale production in a short time. Furthermore, the arched supports need to be manually stacked after production, which not only involves a large workload and high labor intensity but also reduces production efficiency. Moreover, when stacking arched supports, they are generally simply piled on a trolley, making the arched supports prone to loosening and shaking during transport. This affects the neat stacking of the arched supports and makes subsequent loading, unloading, and transfer difficult for workers. Summary of the Invention

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Example 1: Refer to Figure 1-19 An automated production line for arched supports includes a press and a frame 1 distributed along the processing line, and further includes:

[0049] The feeding conveyor roller 2 is located at the front end of the frame 1 and is used to feed the structural steel.

[0050] The movable length setting part 3 is located at the end of the feeding conveyor roller 2 and is used to position the steel cutting position. A cutting machine is provided on the side of the movable length setting part 3.

[0051] Stepping conveyor 4 is disposed on the side of the moving fixed length section 3 and is perpendicular to the moving fixed length section 3. It is used to realize the stepping lateral movement of the cut steel section. A first auxiliary conveying roller 28 is provided between the stepping conveyor 4 and the moving fixed length section 3.

[0052] The clamping roller mechanism 30 is set at the feeding end of the stepping conveyor 4 and is used to clamp and convey the steel profile. The press is placed on the upper side of the clamping roller mechanism 30. A second auxiliary conveying roller track 29 is provided between the clamping roller mechanism 30 and the stepping conveyor 4.

[0053] The clamping pull-out part 5 is located at the end of the stepping conveying part 4 and is used to clamp the steel section on the pull-out clamping and conveying roller mechanism 30.

[0054] Tilting part 6, located at the end of clamping pull-out part 5, is used to tilt and flatten the steel profile that is arched and upright due to pressing.

[0055] The receiving and inspection roller conveyor 7 is located on the side of the tilting part 6 and is arranged parallel to the tilting part 6.

[0056] The collection platform 8 is located at the end of the frame 1 and is used to stack steel sections and push the neatly stacked steel sections to the feeding trolley 17.

[0057] Specifically, the feeding conveyor roller 2 transports a section of steel to the moving fixed-length section 3. A plasma cutting machine (currently in use) cuts the steel according to the pre-set trajectory. After cutting, the first auxiliary conveyor roller 28 sends the cut steel to the stepping conveyor section 4. The stepping conveyor section 4 repeatedly transports the cut steel to the second auxiliary conveyor roller 29 according to a stepping rhythm. When the steel reaches the clamping roller mechanism 30, the clamping roller mechanism 30 clamps the steel and feeds it into the press mold. The press begins to press down on the steel. Because the length of the steel is greater than the mold length, it needs to be pressed three times to form the shape. The clamping roller mechanism 30 feeds the steel a second time, but the clamping rollers are insufficient for the third feeding. Material conditions require the clamping and pulling part 5 to pull out the remaining part. The clamping and pulling part 5 clamps and pulls the pressed arched steel bracket out of the press mold and pulls it to the tilting part 6. The tilting part 6 tilts the arched steel bracket, which is upright due to pressing, and lays it flat. The receiving and inspection roller conveyor 7 receives and transports the flat arched steel bracket. The arched steel bracket is inspected during transportation. The qualified arched steel bracket is sent to the collection platform 8 to start stacking. The neatly stacked arched steel bracket is pushed to the feeding trolley 17 by stepping. The feeding trolley 17 transports the arched steel bracket outside the site for manual unloading. After unloading, the manual control of the feeding trolley 17 returns to the collection station.

[0058] This application achieves continuous conveying and processing of steel profiles by rationally arranging the production process of the steel arch frame 19 and through various automated mechanisms, so that the steel profile raw materials are processed into arch supports. The degree of automation is high, which reduces the labor intensity of workers, reduces the waste of raw materials, and has high production efficiency, making it very practical.

[0059] Example 2: Refer to Figure 1-3 An automated production line with an arched support structure, based on embodiment 1, further includes a first auxiliary conveyor roller 28, a second auxiliary conveyor roller 29, a feeding conveyor roller 2, and a receiving and detection roller 7 with the same structure. Each of the first auxiliary conveyor roller 28, the second auxiliary conveyor roller 29, the feeding conveyor roller 2, and the receiving and detection roller 7 includes a first frame base 9 fixed on a frame 1. Several conveyor rollers 901 are rotatably connected to the first frame base 9. Each conveyor roller 901 has a sprocket 902 at its end, and a chain 903 is provided between the multiple sprockets 902. A base 10 is fixed on one side of the first frame base 9, and a conveyor motor 1001 is provided on the base 10. Both the conveyor motor 1001 and one of the conveyor rollers 901 are provided with a synchronous pulley 1002, and a synchronous belt is provided between the two synchronous pulleys 1002.

[0060] Specifically, when the roller conveyor is working, the conveyor motor 1001 is controlled to run. The output shaft of the conveyor motor 1001 drives one of the conveyor rollers 901 on the first frame 9 to rotate through the synchronous pulley 1002 and the synchronous belt. During the rotation of the conveyor roller 901, the other conveyor rollers 901 are driven to rotate through the sprocket 902 and the chain 903, thereby realizing the conveying and transfer of the steel profile.

[0061] Example 3: Reference Figure 1-3 An automated production line for arched supports, based on embodiment 2, further includes a detection component 904 on the first frame 9 of the receiving and detection roller conveyor 7. The detection component 904 includes a laser sensor and a laser camera, which are electrically connected to a back-end terminal.

[0062] Specifically, when the steel profiles pressed into arched supports are conveyed on the receiving and inspection roller conveyor 7, the pressed workpieces are scanned and inspected by laser or infrared detection instruments. The results of the calculations are compared and analyzed with the parameters of the workpiece drawings, and the back-end terminal finally determines whether the pressed steel profiles are qualified.

[0063] Example 4: Reference Figure 4-5 An automated production line for an arched support, based on embodiment 3, further includes a moving fixed-length section 3 comprising a second frame 11 fixed on the frame 1 and arranged parallel to the first frame 9 of the feeding conveyor roller 2. A scale 111 and a moving motor 112 are fixed on the second frame 11. A first lead screw 113 connected to the output shaft of the moving motor 112 is rotatably connected to the second frame 11. A lead screw nut 114 is threaded onto the first lead screw 113. A hydraulic lifting arm 115 is fixed on the top of the lead screw nut 114. A limit stop 116 is provided on the hydraulic lifting arm 115.

[0064] Specifically, based on the length of the steel section to be cut, the moving motor 112 is controlled to run. The output shaft of the moving motor 112 drives the first lead screw 113 to rotate. When the first lead screw 113 rotates, the threaded nut 114 on the outer side drives the hydraulic lifting arm 115 to move along its axial direction. The hydraulic lifting arm 115 moves to the end of the steel section and controls the limit block 116 to move down to limit the end of the steel section, ensuring the steel section is at the stop position. Then, the cutting machine is controlled to cut the steel section at the dimension corresponding to the scale 111.

[0065] Example 5: Refer to Figure 6An automated production line for arched supports, based on embodiment 4, further includes a stepping conveyor 4 comprising a third frame 12 fixed on the frame 1 and perpendicular to the second frame 11. The third frame 12 has a positioning baffle 121 fixed on its side, opposite to the moving fixed length part 3. A conveying cylinder 122 is fixed on the third frame 12. The piston rod of the conveying cylinder 122 is connected to a pushing crossbeam frame 123. The pushing crossbeam frame 123 slides on the third frame 12. Each crossbeam of the pushing crossbeam frame 123 is provided with several first claws 124 that move against the steel profile. A first torsion spring is provided between the first claws 124 and the crossbeams of the pushing crossbeam frame 123.

[0066] Specifically, after the steel section is cut, the hydraulic lifting arm 115 raises the limit stop 116, and the steel section is continued to be conveyed and transported by the second auxiliary conveying roller 29 to the third frame 12 until it is restricted from moving by the positioning baffle 121 on the third frame 12. When the transfer cylinder 122 is working, it controls its piston rod to pull the push beam 123 back and forth. The push beam 123 relies on the first claw 124 to step-by-step convey the steel section on the third frame 12. When the push beam 123 moves back, the first claw 124 is blocked by the steel section subsequently conveyed to the third frame 12. The first claw 124 is forced to flip and avoid the steel section. When the push beam 123 continues to push, the first claw 124 resets and continues to push the steel section placed on the third frame 12.

[0067] Example 6: Refer to Figure 7 , Figure 8 , Figure 9 and Figure 18 An automated production line for arched supports, based on embodiment 5, further includes a clamping and pulling-out part 5 comprising a fourth frame base 13 fixedly mounted on the frame 1. A transverse motor 131 is fixedly mounted on the fourth frame base 13. The output shaft of the transverse motor 131 is connected to a first screw 132 rotatably connected to the fourth frame base 13. A first sleeve 133 is threadedly connected to the first screw 132. A transverse frame slidably connected to the fourth frame base 13 is fixed on the first sleeve 133. 134. A longitudinal motor 135 is fixedly mounted on the transverse frame 134. The output shaft of the longitudinal motor 135 is connected to a second screw 136 that is rotatably connected to the transverse frame 134. A second sleeve 137 is threadedly connected to the second screw 136. A longitudinal frame 138 that is slidably connected to the transverse frame 134 is fixedly mounted on the second sleeve 137. A rotary motor 139 is fixedly mounted on the longitudinal frame 138. The output shaft of the rotary motor 139 is connected to a rotary seat 14. A clamping component is provided on the rotary seat 14.

[0068] Furthermore, the clamping component includes clamping cylinders 141 fixed on both sides of the rotating seat 14. Each clamping cylinder 141 has a connecting plate 142 connected to its piston rod. The end of the connecting plate 142 is provided with a clamping claw 143. A guide rod 144 is fixed on the rotating seat 14. The connecting plate 142 is slidably connected to the guide rod 144.

[0069] Furthermore, the pinch roller mechanism 30 includes a sixth frame 3001 fixed on the frame 1. The sixth frame 3001 is provided with an upper bearing seat 3002 and a lower bearing seat 3003. Conveyor wheels 3004 are rotatably connected inside both the upper bearing seat 3002 and the lower bearing seat 3003. A drive motor 3005 for driving the conveyor wheels 3004 inside the lower bearing seat 3003 is fixed on the sixth frame 3001. A hydraulic cylinder 3006 for driving the upper bearing seat 3002 to rise and fall is fixed on the sixth frame 3001. A lifting cylinder 3007 is fixed on the sixth frame 3001. The piston rod of the lifting cylinder 3007 is connected to a pneumatic baffle 3008.

[0070] Specifically, the hydraulic cylinder 3006 drives the upper bearing seat 3002 to move, adjusting the distance between the two conveying wheels 3004. The lifting cylinder 3007 drives the pneumatic baffle 3008 to move, achieving the function of aligning and positioning the incoming material, limiting the end of the steel section, and controlling the drive motor 3005 to run. The drive motor 3005 drives the conveying wheel 3004 on the lower bearing seat 3003 to rotate, cooperating with the conveying wheel 3004 in the upper bearing seat 3002 to convey the steel section. When the steel section reaches the clamping roller mechanism 30, the conveying wheel 3004 clamps the steel section and sends it into the press mold (the press is existing technology). The press begins to press down to press the steel section. Since the length of the steel section is greater than the length of the mold, it needs to be pressed three times to form the shape. The clamping roller is insufficient for the second and third feeding operations, requiring coordination. The clamping and pulling part 5 pulls out the remaining part for pressing. Depending on the different radii of the steel profile, the gripping points are different. The transverse motor 131 and the longitudinal motor 135 are controlled to work, so that the clamping parts on the rotating seat 14 move to the designated position to grip the steel profile. The clamping claw 143 is in the open state. Then the clamping cylinder 141 is controlled to work, so that the clamping cylinder 141 drives the clamping claw 143 to clamp and pull the steel profile through the connecting plate 142. The guide rod 144 can improve the stability of the connecting plate 142 when it moves. Then the transverse motor 131 is controlled to work, so that the first sleeve 133 moves axially along the first screw 132, and then cooperates with the press to pull out the remaining part of the steel profile for pressing. Then the clamping claw 143 clamps the pressed steel arch frame 19 and removes it from the mold by flipping the angle. The clamping claw 143 feeds the pressed steel arch frame 19 to the tilting part 6.

[0071] Example 7: Refer to Figure 10-12An automated production line for arched supports, based on embodiment 6, further includes a tilting section 6 comprising a fifth frame base 15 fixed on the frame 1, a tilting cylinder 151 mounted on the fifth frame base 15, a tilting frame 16 movably connected to the piston rod of the tilting cylinder 151, and a tilting frame 16 rotatably connected to the fifth frame base 15 via a pin. The tilting frame 16 includes a connecting seat 161 rotatably connected to the fifth frame base 15, a horizontal seat 162 fixed to the connecting seat 161, several vertical plates 163 fixed on the horizontal seat 162, and support plates 164 mounted on the vertical plates 163.

[0072] Specifically, after the clamping and pulling part 5 moves the pressed steel arch frame 19 to the tilting part 6, the steel arch frame 19 is placed on the support position of the upright plate 163 and the support plate 164 on the horizontal seat 162. Then, the tilting cylinder 151 is controlled to run. The tilting cylinder 151 drives the horizontal seat 162 to rotate around the pin shaft connected to the fifth frame seat 15 through the connecting seat 161, so that the vertically placed steel arch frame 19 is placed flat on the receiving and inspection roller conveyor 7.

[0073] Example 8: Refer to Figure 13-14 An automated production line for an arched support structure, based on embodiment 7, further includes a collection platform 8 located beside the end of the receiving and inspection roller conveyor 7. The end of the first support seat 9 of the receiving and inspection roller conveyor 7 is fixed with a limiting plate that moves against the structural steel. The collection platform 8 includes a collection seat 801 and a pusher seat 802 fixed on both sides of the receiving and inspection roller conveyor 7. Both the collection seat 801 and the pusher seat 802 are fixed with a pusher cylinder 803. The piston rod of the pusher cylinder 803 is fixed with a pusher plate 8031. A second pawl 8032 is rotatably connected to the pusher plate 8031 ​​via a pin. A second torsion spring for resetting the second pawl 8032 is sleeved on the pin.

[0074] Specifically, after the receiving and inspection roller conveyor 7 completes the inspection of the steel arch frame 19 in the conveyor, the steel arch frame 19 continues to move until it reaches the end of the receiving and inspection roller conveyor 7 and is limited by the limiting plate. At this time, the pushing cylinder 803 on the pushing seat 802 works, and the steel sections that have moved to the end of the receiving and inspection roller conveyor 7 are pushed one by one to the collecting seat 801 and stacked through the pushing plate 8031. After the number of steel arch frames 19 stacked on the collecting seat 801 reaches a certain number, the pushing cylinder 803 on the collecting seat 801 is controlled to work. The pushing cylinder 803 uses the second claw 8032 on the pushing plate 8031 ​​to move the neatly stacked steel arch frames 19 horizontally to the feeding trolley 17.

[0075] Example 9: Refer to Figure 15An automated production line for an arched support, based on embodiment 8, further includes a traveling track 18 set on one side of the collection platform 8, a feeding trolley 17 sliding on the traveling track 18, a side plate 171 fixed on the top of the feeding trolley 17 away from the collection platform 8, a groove 172 opened on the side of the feeding trolley 17 away from the side plate 171, a limiting block 173 slidably connected in the groove 172, a pressing slope opened on the side of the limiting block 173 near the collection platform 8, and a first elastic element 174 provided between the limiting block 173 and the inner wall of the groove 172.

[0076] Specifically, during the pushing process, the steel arch frame 19 pushed from the collection platform 8 onto the feeding trolley 17 exerts a pushing force on the pressing slope of the limiting block 173. The limiting block 173 is forced to retract into the groove 172 to avoid the movement of the steel arch frame 19 until one side of the neatly stacked steel arch frame 19 abuts against the side plate 171 and the other side passes over the limiting block 173. The limiting block 173 is reset under the push of the first elastic element 174 and cooperates with the side plate 171 to limit the other side of the steel arch frame 19, so as to prevent the neatly stacked steel arch frame 19 from loosening due to shaking when the feeding trolley 17 moves along the travel track 18 to feed materials, thereby ensuring the neat stacking state of the steel arch frame 19.

[0077] Example 10: Refer to Figure 16-17 An automated production line for an arched support, based on embodiment 8, further includes a receiving groove 20 on the limiting block 173, a first rotating rod 21 fixedly disposed in the receiving groove 20, a first torsion spring disposed between the first rotating rod 21 and the limiting block 173, a first swing plate 22 rotatably connected to the outside of the first rotating rod 21, a second rotating rod 23 rotatably connected to the first swing plate 22, a second torsion spring disposed between the second rotating rod 23 and the first swing plate 22, a second swing plate 24 fixedly disposed on the second rotating rod 23, and angle limiting components disposed at the second swing plate 24 and the first swing plate 22.

[0078] Furthermore, the angle limiting assembly includes a rubber pad 25 fixed on the second swing plate 24, a cavity 251 is formed in the rubber pad 25, two pneumatic cavities 26 are formed on the first swing plate 22, the cavity 251 and the pneumatic cavities 26 are connected by an air pipe, a piston body 261 is slidably connected in each pneumatic cavity 26, a second elastic element 262 is fixed on the piston body 261, and a limiting rod 263 that is slidably connected to the first swing plate 22 is connected to the end of the second elastic element 262 away from the piston body 261. A plurality of circumferential limiting holes 264 that cooperate with the limiting rod 263 are formed on the first rotating rod 21 and the second rotating rod 23.

[0079] Specifically, initially, the second swing plate 24 is on the same plane as the first swing plate 22 under the action of the second torsion spring. The first swing plate 22 is inclined to the limiting block 173 under the action of the first torsion spring. When the limiting block 173 moves down into the groove 172, the first swing plate 22 moves down synchronously and is pressed by the side wall of the groove 172. The first swing plate 22 drives the second swing plate 24 to move into the receiving groove 20. After the stacked steel arch frame 19 passes the limiting block 173 and abuts against the side plate 171, the limiting block 173 moves up under the elastic force of the first elastic element 174. The first swing plate 22 then returns to its original swing position under the action of the first torsion spring. During this period, the second swing plate 24 at the upper end of the first swing plate 22 abuts against the steel arch frame 19. The second swing plate 24 abuts against the steel arch frame 19 through the rubber pad 25 at its end. The rubber pad 25 is subjected to The air compressed in the internal cavity 251 is introduced into the two pneumatic chambers 26 of the first swing plate 22 through the air pipe. The piston body 261 in the two pneumatic chambers 26 is pushed by the air. The piston body 261 drives the limiting rod 263 to move through the second elastic element 262, so that the limiting rod 263 in the two pneumatic chambers 26 are respectively inserted into the limiting holes 264 of the first rotating rod 21 and the second rotating rod 23. This fixes the position between the first swing plate 22 and the first rotating rod 21, and the position between the first swing plate 22 and the second rotating rod 23. This keeps the second swing plate 24 in contact with the steel arch frame 19, and prevents the neatly stacked steel arch frame 19 from loosening due to shaking when the feeding trolley 17 moves along the walking track 18 to feed materials. This ensures the neat stacking of the steel arch frame 19 and facilitates subsequent operations by the staff.

[0080] Example 11: Refer to Figure 16-17 An automated production line for an arched support, based on embodiment 8, further includes a pull rope 27 fixed on the limiting rod 263. The end of the pull rope 27 away from the limiting rod 263 passes through the first swing plate 22 and extends outward. The pull rope 27 is placed in the rodless cavity of the pneumatic cavity 26.

[0081] Specifically, when it is necessary to release the movement restriction on the steel arch frame 19, the staff only needs to pull the pull rope 27 to pull the limit rod 263. The limit rod 263 squeezes the second elastic element 262 and retracts into the pneumatic cavity 26, so that the limit rod 263 releases the movement restriction between the second rotating rod 23 and the first swing plate 22, and then moves the second swing plate 24 away from the steel arch frame 19, so as to facilitate the removal of the steel arch frame 19.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
