Technical Field

[0001] This invention belongs to the field of automatic mattress production technology, and in particular relates to an automatic production line for mattress bed netting. Background Technology

[0002] A mattress mesh refers to the metal support structure inside a mattress, consisting of a frame, springs, and butterfly springs. In the current mattress mesh production process, the frame, springs, and butterfly springs are generally stacked on one side. Production workers then take the corresponding materials from the pile and assemble them into the mattress mesh.

[0003] During the assembly and fixing of the frame and the butterfly support spring, the edge of the butterfly support spring is first aligned with the frame, and then the frame and the butterfly support spring are fixed by U-shaped nails using a handheld nailing machine. This process is highly dependent on manual labor and restricts the improvement of production efficiency. Summary of the Invention

The base plate has an upwardly bent support plate on the side of the U-shaped nail roll away from the nailing machine. A side baffle for guiding the U-shaped nail strip to one side is fixedly mounted on the base plate. The mounting base has a nailing machine on the side away from the U-shaped nail roll. The nailing machine has a nail feeding guide rail extending above the base plate. A height limiting baffle is provided on the upper surface of the feeding end of the nail feeding guide rail. The end of the height limiting baffle facing the feeding end is curved upward.

[0009] The upper nailing structure further includes a vertical guide plate, which is slidably mounted to the guide shaft and connected to the drive motor. A front and rear adjustment rail is fixedly provided on the side of the vertical guide plate away from the guide shaft. The mounting base of the upper nailing structure is slidably mounted to the front and rear adjustment rail via a slider.

A rotary motor is fixedly mounted on the fixed base, and the power output end of the rotary motor is meshed with the transmission gear, driving the storage turntable to rotate. Several storage positions are arranged around the upper surface of the storage turntable. Each storage position has two vertically extending storage columns corresponding to the circular part of the disc spring. The same storage plate is slidably mounted on the two storage columns at each storage position. The end of the storage column connected to the upper surface of the storage turntable is fixed. A gap-relief washer is fixedly installed to lift and isolate the storage plate; a lifting structure is also fixedly installed on the fixed base to lift the butterfly support spring on the storage position to detach it from the storage column. The lifting structure includes a support base fixedly installed on the fixed base, a lifting guide rail extending vertically on one side of the support base, a lifting motor fixedly installed on the top of the support base and on one side of the lifting guide rail, a lifting screw connected to the power output end of the lifting motor, a lifting threaded sleeve connected to the lifting screw, a lifting guide seat fixedly connected to the lifting threaded sleeve, a lifting guide seat slidably connected to the lifting guide rail, and a butterfly spring lifting rod extending to below one of the storage plates is also fixedly installed on the lifting guide seat.

[0011] The aforementioned butterfly spring feeding structure includes a feeding track fixedly installed on a fixed base. The feeding track is a rodless cylinder. A left-right adjustment structure is fixedly installed on the slider of the feeding track. The left-right adjustment structure is also a rodless cylinder, and the sliding direction of the slider of the left-right adjustment structure is perpendicular to the sliding direction of the slider of the feeding track.

Both fingers of the pneumatic fingers are fixedly equipped with gripping parts. The gripping parts are semi-frustum shaped, and the diameter of the end connected to the finger is larger than the other end. The diameter of the end of the gripping part closer to the finger is larger than the circular part of the butterfly spring, and the diameter of the other end is smaller than the circular part of the butterfly spring. The two gripping parts can be combined to form a frustum shaped structure.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. Through the cooperation of the frame material storage structure, frame feeding structure, nail fixing structure, butterfly spring material storage structure and butterfly spring feeding structure, the automatic feeding and nail fixing of the frame and butterfly support spring can be realized, realizing the automated production of mattress bed net, reducing the dependence on manpower and improving production efficiency.

[0014] 2. The frame lifting rods in the frame material storage structure can separate the frames and prevent them from getting tangled and crushed. The top of the lifting chain is an arc-shaped structure. When the frame is lifted to the top, it will have a certain lateral displacement and be misaligned with other frames, which is convenient for picking up and putting down. At the same time, since the top of the lifting chain is an arc-shaped structure, the top frame lifting rods form a trumpet-shaped structure, which also facilitates picking up and putting down materials.

[0015] 3. The design of the frame clamp and V-shaped groove in the frame feeding structure can ensure that the frame is firmly clamped and prevent the frame from falling off on its own during the conveying process.

[0016] 4. The storage column in the butterfly spring storage structure can standardize the storage of the butterfly support spring and avoid scattering. In addition, the butterfly spring feeding structure utilizes the elasticity of the circular spring part of the butterfly support spring and fixes the butterfly support spring by expanding the gripper. The resistance of elastic force and expansion force makes the clamping more firm and stable. At the same time, it does not require precise control position, which can reduce control accuracy.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] As attached Figure 1-30 The automatic production line for mattresses and mattresses shown includes a frame 1. A frame storage structure 2 is installed at one end of the frame 1. A frame feeding structure 3 is automatically slidably installed on the upper part of the frame 1. One end of the sliding stroke of the frame feeding structure 3 is located above the frame storage structure 2, and a production table 4 is set below the other end of the stroke. The frame is fed from the frame storage structure 2 to the production table 4 through the frame feeding structure 3. Nail fixing structures 5 are slidably installed on both sides of the production table 4 on the frame 1. A butterfly spring storage structure 6 is synchronously slidably installed on one side of the nail fixing structure 5. A butterfly spring feeding structure 7 is fixedly installed on one side of the butterfly spring storage structure 6. The butterfly spring feeding structure 7 feeds the butterfly spring from the butterfly spring storage structure 6 to the production table 4 and fixes it. Then, the frame and the butterfly spring are fixedly connected by the nail fixing structure 5.

[0049] In a preferred embodiment, a rotating tray 11 is rotatably mounted on one end of the frame 1 via a bearing. Two frame storage structures 2 are detachably mounted on the rotating tray 11; one is in use, and the other is on standby. When the frames in the currently used frame storage structure 2 are depleted, the rotating tray 11 rotates to rotate the frame storage structure 2, and the empty frame storage structure 2 is reloaded. In actual production, since the frame production speed is greater than the bed net assembly speed, multiple frame storage structures 2 can be set up for loading and storing frames. The frame storage structure 2 includes a storage base plate 21, with a main servo motor 211 mounted in the center of the upper surface of the storage base plate 21. The two sides of the main servo motor 211 (according to...) Figure 2 (As shown in the direction), a secondary servo motor 212 is installed at the upper left and lower right of the storage substrate 21. Eight lifting mechanisms for storing and raising the frame are fixedly installed on the upper surface of the storage substrate 21. Two lifting mechanisms are distributed on each side of the storage substrate 21. The four lifting mechanisms located at the lower left and upper right form a quadrilateral main lifting group. The two lifting mechanisms located at the upper left and the two lifting mechanisms located at the lower right form two secondary lifting groups. Each secondary lifting group contains two lifting mechanisms. The power output end of the main servo motor 211 is connected to a gear reducer. The gear reducer is then connected to two drive shafts extending to the lower left and upper right respectively. The drive shafts are then connected to the two lifting mechanisms on the corresponding side through bevel gears and other drive shafts, so that all lifting mechanisms in the main lifting group are connected to the main servo motor 211. The secondary servo motors 212 located at the upper left and lower right are also connected to the secondary lifting groups on the corresponding side through a new gear reducer and drive shaft. The servo motors drive the lifting mechanisms to raise and lower the frame for feeding and storage.

[0050] The frame lifting mechanism includes a frame fixing frame 22 extending vertically. A sprocket 23 is mounted on the upper and lower parts of the frame fixing frame 22. The lower sprocket 23 is connected to a corresponding servo motor. The two sprockets 23 are connected by the same lifting chain 24. The lifting chain 24 is a double-layer chain, consisting of two chain links fixedly connected side-by-side to form a chain group. Multiple chain groups are connected end-to-end to form a closed-loop multi-layer chain structure. The sprockets 23 are double-layer sprockets that match the double-layer chain. A tensioning wheel 25, which meshes with the lifting chain 24, is installed on the fixed frame 22. The tensioning wheel 25 is a double-layer tensioning wheel that matches the double-layer chain. Each link in the lifting chain 24 has a vertically extending frame lifting rod 241 on its outer side. One chain group has two links fixed side by side, for a total of four frame lifting rods 241. Storage space is left between the frame lifting rods 241 of adjacent links. The frame lifting mechanism is driven by a servo motor to lift and feed the frame and lower it for storage. The frame fixing frame 22 also has... A guide cover 26 is installed, comprising a main cover 261 and a secondary cover 262. A support frame 221 is fixedly installed on one side of the frame fixing bracket 22. The main cover 261 is fixedly installed on the frame fixing bracket 22, and the secondary cover 262 is fixedly installed on the support frame 221. A guide groove 263 matching the shape of the lifting chain 24 is formed between the main cover 261 and the secondary cover 262. A telescopic cylinder 2 is fixedly installed at the top of the frame fixing bracket 22 and inside the main cover 261. 7. The telescopic end of the telescopic cylinder 27 is rotatably connected to one end of the locking rod 271. The locking rod 271 is also rotatably connected to the rotating seat 272. The rotating seat 272 is fixedly installed on the side of the telescopic cylinder 27 facing the guide groove 263. Both the main cover 261 and the auxiliary cover 262 are provided with through grooves 264 whose shape matches the locking rod 271. The telescopic cylinder 27 drives the locking rod 271 to extend out of the main cover 261 and cross the guide groove 263. When the locking rod 271 extends, it can prevent the top edge from coming off.

[0051] During storage, the frame falls onto the storage space of the lifting chain 24 under the action of the guide groove 263. Then, the servo motor drives the sprocket 23 to rotate, which in turn drives the lifting chain 24 to rotate. At this time, the frame moves with the lifting chain 24 and gradually descends for storage. The new storage space on the lifting chain 24 replaces the storage space that already has frames and waits for new frames until the entire storage structure 2 is full. After the storage structure 2 is full, it can be replaced with a new storage structure 2 to continue storing. The full storage structure 2 can be transported to one side for standby or directly installed on the standby position of the rotating tray 11 for rotation. During retrieval, the servo motor drives the sprocket 23 to rotate in the opposite direction and lifts the frame to facilitate retrieval by the frame feeding structure 3. Due to the separation of the lifting rod 241, multiple frames do not contact each other, avoiding entanglement between the frames.

[0052] The frame feeding structure 3 includes a movable base 31. A frame feeding slide rail 12 is provided on each side of the upper surface of the frame 1, and a frame feeding rack 13 is provided on one side of each frame feeding slide rail 12. The movable base 31 is provided with four guide sliders 311 that slide and match the frame feeding slide rails 12. Each pair of guide sliders 311 corresponds to one frame feeding slide rail 12. The movable base 31 is also provided with a sliding motor 312. A gear meshing with the frame feeding rack 13 is fixedly installed at the power output end of the sliding motor 312, driving the movable base 31 to slide on the frame 1. Four frame butterfly spring lifting cylinders 742 are also fixedly installed on the movable base 31. The telescopic ends of the frame butterfly spring lifting cylinders 742 extend downwards. A common gripping lifting frame 33 is fixedly connected below the telescopic ends of all the frame butterfly spring lifting cylinders 742. Eight downward-extending gripping cylinders 34 are fixedly installed on the periphery. A vertically extending first guide rod 342 is slidably connected to one side of the gripping cylinder 34 via a first linear bearing 341. The end of the first guide rod 342 is fixedly connected to the telescopic end of the gripping cylinder 34. A pneumatic gripper 35 is installed at the lower end of the gripping cylinder 34. A frame clamp 351 is fixedly installed on each gripper finger of the pneumatic gripper 35. A horizontally extending second guide rod 353 is fixedly installed on one frame clamp 351, and a second linear bearing 354 is fixedly installed on the other frame clamp 351. The second guide rod 353 and the second linear bearing 354 are slidably connected. The two frame clamps 351 can fit together and separate under the drive of the pneumatic gripper 35. V-shaped clamping grooves 352 are provided at the fitting points of the two frame clamps 351, and the openings of the two V-shaped clamping grooves 352 are close to each other.

[0053] When the frame feeding structure 3 is running, the sliding motor 312 first drives the moving seat 31 to move above the frame storage structure 2. The frame lifting cylinder 742 is activated and drives the gripping lifting frame 33 to descend. Then, the gripping cylinder 34 is activated and drives the pneumatic gripper 35 to descend until the V-shaped clamping groove 352 is at the same height as the frame. The pneumatic gripper 35 is activated and drives the frame clamping frame 351 to clamp the frame into the V-shaped clamping groove 352. Then, the frame lifting cylinder 742 and the gripping cylinder 34 are reset and the frame is lifted. At this time, the sliding motor 312 is activated again and drives the moving seat 31 to move above the production table. Then, the frame lifting cylinder 742 and the gripping cylinder 34 are activated again and send the frame down to a suitable height. The pneumatic gripper 35 is driven to release the frame, thus completing one frame gripping and transportation process.

[0054] The nailing fixing structure 5 includes a translation guide rail 51 disposed on one side of the frame 1. A translation base 52 is slidably mounted on the translation guide rail 51. Two translation rods 521 are fixedly disposed on the lower surface of the translation base 52. The translation base 52 is connected to a slider slidably mounted on the translation guide rail 51 through the translation rods 521. The translation guide rail 51 is a combination of a lead screw motor and a lead screw sleeve. A lifting guide seat 53 is vertically mounted on the upper surface of the translation base 52. The lifting guide seat 53 is provided with... The system comprises two guide shafts 531. A lifting guide seat 53 has a drive motor and a nail-driving adjusting screw 532 positioned between the two guide shafts 531. A lower nail-driving structure 54 is fixedly mounted on the lower part of the guide shafts 531. An upper nail-driving structure 55 is also vertically slidable on the guide shafts 531 via a slider. The drive motor is connected to the upper nail-driving structure 55 via the engagement of the nail-driving adjusting screw 532 and a threaded sleeve, driving the upper nail-driving structure 55 to slide. Both the upper nail-driving structure 55 and the lower nail-driving structure 54 are enclosed... The system includes a mounting base 56, on which a U-shaped nail roll 561 is rotatably mounted. A U-shaped nail strip 562 is wound around the U-shaped nail roll 561. A base plate 57 for supporting the U-shaped nail strip 562 is fixedly mounted between the U-shaped nail roll 561 and the mounting base 56. The base plate 57 has an upwardly bent support plate 571 on the side of the U-shaped nail roll 561 away from the nailing machine 563. A side guide for guiding the U-shaped nail strip 562 to one side is fixedly mounted on the base plate 57. The side of the baffle 572 facing the U-shaped nail roll 561 is an inclined section, which brings the U-shaped nail strip 562 to one side of the bottom support plate 57. The mounting base plate 56 is provided with a nailing machine 563 on the side away from the U-shaped nail roll 561. The nailing machine 563 is provided with a nail feeding guide rail 564 extending above the bottom support plate 57. The nail feeding guide rail 564 is provided with a height limiting baffle 565 on the upper surface of the feeding end. The end of the height limiting baffle 565 facing the feeding end is curved upward.

[0055] The upper nailing structure 55 further includes a vertical guide plate 551, which is slidably mounted on the guide shaft 531 and connected to the drive motor. A front and rear adjustment rail 58 is fixedly provided on the side of the vertical guide plate 551 away from the guide shaft 531. The mounting base plate 56 of the upper nailing structure 55 is slidably mounted on the front and rear adjustment rail 58 via a slider. A first front and rear cylinder 552 is also fixedly mounted on the vertical guide plate 551. The telescopic end of the first front and rear cylinder 552 is rotatably connected to the mounting base plate 56 of the upper nailing structure 55. The lower nailing structure 54 further includes a fixed guide plate 541, which is fixedly mounted on the guide shaft 531. A front and rear adjustment rail 58 is fixedly provided on the side of the fixed guide plate 541 away from the guide shaft 531. The mounting base plate 56 of the lower nailing structure 54 is slidably mounted on the front and rear adjustment rail 58 via a slider. A second front and rear cylinder 542 is also rotatably mounted on the translation base 52. The telescopic end of the second front and rear cylinder 542 is rotatably connected to the mounting base plate 56 of the lower nailing structure 54.

[0056] In operation, the total travel distance and the travel distance of the translation base 52 are first set according to the specifications of the bed net. Then, the height of the upper nailing structure 55 is controlled according to the thickness of the bed net, so that the distance between the working positions of the upper nailing structure 55 and the lower nailing structure 54 is equal to the thickness of the bed net. Then, the work officially begins. The translation base 52 moves to the starting position, and the first and second front-to-back cylinders 552 and 542 are activated to drive the upper nailing structure 55 and the lower nailing structure 54 forward and nail. The first and second front-to-back cylinders 552 and 542 then reset, causing the upper nailing structure 55 and the lower nailing structure 54 to move backward. The translation base 52 moves to the second nailing position, and the first and second front-to-back cylinders 552 and 542 are activated again to drive the upper nailing structure 55 and the lower nailing structure 54 forward and nail. The process is then repeated until the nailing and fixing work is completed.

A gap-reducing washer 625 is fixedly installed at the end of each storage column 623 that connects to the upper surface of the storage turntable 62 to lift and isolate the storage plate 624. When the storage plate 624 descends to its lowest position, it engages with the storage turntable. Sufficient space is left between the discs 62 for inserting the butterfly spring lifting rod 66; a lifting structure for lifting the butterfly spring on the storage position to disengage from the storage column 623 is also fixedly installed on the fixed base 61. The lifting structure includes a support base 63 fixedly installed on the fixed base 61. A lifting guide rail 631 extending vertically is provided on one side of the support base 63. A lifting motor 64 is fixedly installed on the top of the support base 63 and on one side of the lifting guide rail 631. The power output end of the lifting motor 64 is connected to... There is a lifting screw 641, which is driven by a lifting threaded sleeve 642. The lifting threaded sleeve 642 is fixedly connected to a lifting guide seat 65. The lifting guide seat 65 is also slidably connected to a lifting guide rail 631. A butterfly spring lifting rod 66 extending to the bottom of one of the storage plates 624 is also fixedly installed on the lifting guide seat 65. The butterfly spring lifting rod 66 extends into the bottom of the storage plate 624 but does not extend to the storage column 623, so as not to affect the rotation of the storage turntable 62.

[0058] When using the product, the manufactured butterfly-shaped support springs are first placed into the storage position. The two circles in the middle of the butterfly-shaped support springs correspond to the two storage columns 623 in the storage position. When the bed net production operation is performed, the lifting motor 64 is started first. The lifting motor 64 can be a servo motor. The lifting motor 64 drives the lifting screw 641 to rotate. The cooperation between the lifting screw 641 and the threaded sleeve 642 uses the butterfly spring lifting rod 66 to slowly lift the storage plate 624 (for easy demonstration of the butterfly spring lifting rod 66). Figure 26 The butterfly spring lifting rod 66 does not actually rise; it should instead be attached to the lower surface of the storage plate 624 to lift the storage plate 624. The butterfly-shaped support springs stored on the storage plate 624 are sequentially lifted to the top of the storage column 623. At this time, the butterfly spring feeding structure 7 removes the first butterfly-shaped support spring from the top of the storage column 623. Then, the lifting motor 64 drives the next butterfly-shaped support spring to the top of the storage column 623, until all the butterfly-shaped support springs at that storage position are removed. At this time, the lifting motor 64 rotates in the reverse direction to reset the butterfly spring lifting rod 66 and the storage plate 624. Then, the rotary motor 622 starts to drive the storage turntable 62 to rotate, rotating the storage plate 624 of the next storage position above the butterfly spring lifting rod 66. Then, the lifting motor 64 continues to repeat the lifting of the butterfly-shaped support springs, realizing automated feeding.

[0059] The aforementioned butterfly spring feeding structure 7 includes a feeding track 71 fixedly installed on a fixed base 61. The feeding track 71 is a rodless cylinder. A left-right adjustment structure 72 is fixedly installed on the slider of the feeding track 71. The left-right adjustment structure 72 is also a rodless cylinder, and the sliding direction of the slider of the left-right adjustment structure 72 is perpendicular to the sliding direction of the slider of the feeding track 71. A rotary cylinder 73 is fixedly installed on the slider of the left-right adjustment structure 72. A butterfly spring lifting cylinder 74 is fixedly installed on the turntable of the rotary cylinder 73. The telescopic end of the butterfly spring lifting cylinder 74 is fixed... A gripping rod 75 is fixedly installed, and two expansion grips 76 are fixedly installed on the gripping rod 75. The distance between the two expansion grips 76 is equal to the distance between the two circular parts of the butterfly support spring. The expansion grips 76 include pneumatic fingers 77, and gripping parts 78 are fixedly installed on both finger parts of the pneumatic fingers 77. The gripping parts 78 are semi-frustum shaped, and the diameter of the end connected to the finger is larger than that of the other end. The diameter of the end of the gripping part 78 near the finger is larger than that of the circular part of the butterfly support spring, and the diameter of the other end is smaller than that of the circular part of the butterfly support spring. The two gripping parts 78 can be assembled into a frustum shaped structure.

[0060] like Figure 27As shown, during use, when the butterfly spring storage structure 6 moves the butterfly-shaped support spring to the appropriate position, the butterfly spring lifting cylinder 74 drives the two expansion grippers 76 to descend to the gripper part 78 and insert into the circular spring part of the butterfly-shaped support spring through the gripper rod 75. The pneumatic finger 77 is activated to cause the two grippers 78 to expand and separate, forming support for the circular spring part of the butterfly-shaped support spring. Through the combination of support force and elasticity, the butterfly-shaped support spring is fixed to the gripper part 78. Then, the butterfly spring lifting cylinder 74 drives the expansion grippers 76 and the butterfly-shaped support spring in the opposite direction. The material rises, and then, according to the preset program, the feeding track 71, the left and right adjustment structure 72, and the rotary cylinder 73 are activated and perform corresponding position control operations, so that the butterfly support spring can be sent to the installation position. At this time, the nail fixing structure 5 fixes the butterfly support spring and the frame. Then, the pneumatic finger 77 starts to control the two grippers 78 to retract and release the fixation of the butterfly support spring. Finally, the feeding track 71, the left and right adjustment structure 72, the rotary cylinder 73, and the butterfly spring lifting cylinder 74 are reset and the next feeding is carried out.
