Description

Technical Field

[0001] This invention relates to the field of lifting and adjusting technology for automated warehouses, specifically to a lifting and adjusting device for a vertical warehouse containing finished nylon fiber cakes. Background Technology

[0002] The vertical warehouse lifting and adjusting device for finished nylon fiber cakes is a specialized device for storing, handling, and adjusting nylon fiber cakes.

[0003] Patent publication number CN212952396U relates to a lifting device for automated warehouse racking, comprising a motor transmission mechanism and a lifting device. The motor transmission mechanism consists of an AC motor and a brake gear. This patent is composed of a pair of driven gears and a pair of crank mechanisms. The motor output power rod is rigidly connected to the brake gears. With this connection method, the torque output by the motor is directly transmitted to the brake gears, achieving efficient power transmission. In addition, the lifting device is equipped with a pair of symmetrical crank mechanisms and a pair of symmetrical driven gears. The crank rods and driven gears are rigidly connected, enabling the crank mechanism to achieve synchronous lifting and efficient power transmission, thereby ensuring the smoothness and synchronicity of warehouse racking lifting. The motor transmission mechanism and the lifting device are intact under the packaging base plate.

[0004] In the aforementioned patent, the crank mechanism achieves synchronous lifting and efficient power transmission, thereby ensuring the smoothness and synchronicity of warehouse rack lifting. The motor transmission mechanism and lifting device are fully integrated under the packaging base plate. However, when handling the processed nylon yarn cakes, the nylon yarn is wrapped around the surface of the I-beam wheel during processing, which makes it easy to damage the surface of the yarn cakes when placing or clamping them. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lifting and adjusting device for a vertical warehouse of finished nylon fiber filament cakes, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a vertical warehouse lifting and adjusting device for finished nylon fiber cakes, comprising a base plate, a storage warehouse fixedly installed on the top of the base plate, multiple shelves fixedly installed on the top of the base plate, a slide rail fixedly installed on the top of the base plate, and an internal support device provided on the top of the base plate.

[0007] The internal support device includes: a first drive unit, a sliding rod, a second drive unit, a turntable, a sliding round rod, a fixed plate, a square plate, a transmission plate, a rubber block, a transmission inclined rod, and a limiting inclined block. The first drive unit is located on the top of the slide rail, the sliding rod is slidably mounted on the top of the first drive unit, the second drive unit is located on the surface of the sliding rod, the turntable is rotatably mounted on the surface of the second drive unit, the turntable contains a third drive unit, the surface of the turntable has an arc-shaped groove, the sliding round rod is slidably mounted on the inner wall of the arc-shaped groove, and the sliding round rod is slidably mounted on the side of the second drive unit near the turntable. The fixed plate is fixedly installed at the end of the sliding round rod away from the second driving device. The square plate is fixedly installed on the side of the fixed plate away from the sliding round rod. The transmission plate is slidably installed on the side of the fixed plate close to the square plate. The rubber block is fixedly installed on the top of the transmission plate. The transmission inclined rod slides through the inner and outer walls of the sliding round rod and the fixed plate. The limiting inclined block is fixedly installed on the surface of the second driving device. When the fixed plate moves, it will drive the transmission inclined rod to move towards the transmission plate. The transmission plate contacts the transmission inclined rod and pushes the transmission inclined rod to move away from the first spring. When the transmission inclined rod moves, it will contact the limiting inclined block.

[0008] The bottom plate is equipped with a protective device to protect the silk cake and a slowing device to limit the movement speed of the sliding rod.

[0009] According to the above technical solution, a No. 1 spring is provided between the square plate and the transmission plate. The transmission plate is in contact with the transmission rod, and the No. 1 spring drives the transmission plate to reset.

[0010] According to the above technical solution, a second spring is provided between the transmission inclined rod and the sliding round rod. The transmission inclined rod contacts the limiting inclined block, and the second spring drives the transmission inclined rod to reset.

[0011] According to the above technical solution, the protective device includes: a collar, a transmission vertical rod, a sliding column, an arc-shaped rod, an arc-shaped block, an electric push rod, a fixed base, a fixed sleeve rod, a triangular block, a positioning rod, and a positioning block. The collar is rotatably mounted on the circumferential surface of the sliding rod, the sliding column is slidably mounted on the surface of the second driving device, the arc-shaped rod is fixedly mounted on the circumferential surface of the sliding column, one end of the transmission vertical rod is fixedly mounted on the circumferential surface of the collar, the other end of the transmission vertical rod is fixedly mounted on the surface of the arc-shaped rod, the arc-shaped block is fixedly mounted on the circumferential surface of the sliding column, and the electric push rod is fixedly mounted on the top of the first driving device. A connecting rod is fixedly installed at the output end of the electric push rod. The connecting rod is fixedly installed on the surface of the sliding rod. The fixed seat is fixedly installed on the top of the second drive device. The fixed sleeve rod is fixedly installed on the inner wall of the fixed seat. The positioning rod is slidably installed on the inner wall of the fixed sleeve rod. The triangular block is fixedly installed on the inner wall of the positioning rod. The positioning block is slidably installed on the inner wall of the fixed sleeve rod. The positioning block is fixedly connected to the positioning rod. When the silk cake gets tangled with other silk cakes or gets snagged on the shelf, the fixed sleeve rod will move and come into contact with the positioning block. The fixed sleeve rod is blocked by the positioning block, preventing the fixed sleeve rod from moving further.

[0012] According to the above technical solution, the arc-shaped block contacts the triangular block, and a No. 3 spring is provided between the positioning block and the fixed sleeve rod, so that the positioning block can be reset by the No. 3 spring.

[0013] According to the above technical solution, the deceleration device includes: a hollow box, a spring, a sliding plate, a limiting plate, and a friction block. The hollow box is fixedly installed on the top of the driving device one. The spring is fixedly installed on the side of the connecting rod near the hollow box. The sliding plate is slidably installed on the inner wall of the hollow box. The limiting plate is fixedly installed on the surface of the sliding plate. The friction block is slidably installed on the inner wall of the hollow box. The friction block is reset by a No. 4 spring, which drives the friction block to move away from the spring. After the friction block moves, it no longer contacts the spring, so that no friction force and deceleration effect are generated.

[0014] According to the above technical solution, the slowing device further includes: two clamping plates, an L-shaped plate, a rotating rod one, a rotating rod two, and a one-way plate. The two clamping plates are fixedly installed on the inner wall of the hollow box. The L-shaped plate is rotatably installed between the two clamping plates. The rotating rod one is fixedly installed at the output end of the electric push rod. The rotating rod two is rotatably installed on the surface of the rotating rod one. The one-way plate is fixedly installed on the side of the rotating rod one near the friction block. The movement of the rotating rod two will push the L-shaped plate to rotate. The rotation of the L-shaped plate will drive the friction block to move. After the friction block moves, it will be repositioned by the limiting plate.

[0015] According to the above technical solution, a No. 4 spring is provided between the friction block and the hollow box, and the L-shaped plate contacts the rotating rod two, so that the friction block is reset by the No. 4 spring.

[0016] This invention provides a lifting and adjusting device for a vertical warehouse storing finished nylon fiber cakes. It has the following beneficial effects:

[0017] (1) In this invention, the rubber block moves and contacts the inner wall of the H-shaped wheel of the silk cake. When picking up and placing the silk cake, the device will contact the inner wall of the H-shaped wheel and pick up the silk cake from the inside by supporting it from the inside. This prevents the fiber from being damaged when picking up from the outside and contacting the fiber wrapped on the outer wall. This improves the protection of the silk cake. The transmission inclined rod moves and contacts the limiting inclined block, so that the sliding round rod cannot continue to move towards the circumference of the turntable. After the clamping is completed, the device will automatically lock, preventing the silk cake from being unable to be transported when the device moves. This improves the stability of the device during operation.

[0018] (2) In this invention, the fixed base moves and drives the positioning rod to move towards the silk cake. The positioning rod moves and contacts the silk cake, protecting the silk cake and preventing it from being scratched during movement. The fixed sleeve rod is blocked by the positioning block, preventing it from moving further. When the silk cake and the shelf are intertwined, the positioning block limits the fixed sleeve rod, preventing the output end of the electric push rod from moving further. This prevents excessive pulling from causing the silk cake fibers to break and the silk cake to loosen, thus improving the practicality of the device.

[0019] (3) In this invention, the spring piece moves and contacts the friction block to generate friction, which reduces the moving speed of the output end of the electric push rod. This prevents the positioning block and the fixed sleeve rod from colliding and being damaged due to the initial speed of the silk cake moving too fast. After the friction block moves, it no longer contacts the spring piece, so that no more friction and slowing effect are generated. This prevents overload due to excessive resistance when the output end of the electric push rod moves in the opposite direction, thus improving the protection effect of the device. The L-shaped plate rotates and drives the friction block to move. After the friction block moves, it is repositioned by the limiting plate, so that the device returns to its initial state and improves the practicality of the device. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 One embodiment of the present invention is: a vertical warehouse lifting and adjusting device for finished nylon fiber cakes, including a base plate 1, a storage warehouse 2 fixedly installed on the top of the base plate 1, a plurality of shelves 3 fixedly installed on the top of the base plate 1, a slide rail 4 fixedly installed on the top of the base plate 1, and an internal support device provided on the top of the base plate 1.

[0032] The internal support device includes: a first drive device 51, a sliding rod 52, a second drive device 53, a turntable 54, a sliding round rod 55, a fixed plate 56, a square plate 57, a transmission plate 58, a rubber block 59, a transmission inclined rod 510, and a limiting inclined block 511. The first drive device 51 is located on the top of the slide rail 4. The sliding rod 52 is slidably mounted on the top of the first drive device 51. The second drive device 53 is located on the surface of the sliding rod 52. The turntable 54 is rotatably mounted on the surface of the second drive device 53. The third drive device is located inside the turntable 54. An arc-shaped groove is formed on the surface of the turntable 54. The sliding round rod 55 is slidably mounted on the inner wall of the arc-shaped groove. The sliding round rod 55 is slidably mounted on the side of the second drive device 53 near the turntable 54. The fixed plate 56 is fixedly mounted on the end of the sliding round rod 55 away from the second drive device 53. The square plate 57 is fixedly mounted on the fixed plate 56. The side of plate 56 away from the sliding round rod 55, the transmission plate 58 is slidably mounted on the side of fixed plate 56 near square plate 57, and the rubber block 59 is fixedly mounted on the top of transmission plate 58. When picking up and placing, the device will contact the inner wall of the I-beam wheel and pick up the silk cake by internal support, preventing damage to the fibers when picking up from the outside due to contact with the fibers wrapped on the outer wall, thus improving the protection of the silk cake. The transmission inclined rod 510 slides through the inner and outer walls of the sliding round rod 55 and fixed plate 56. The limiting inclined block 511 is fixedly mounted on the surface of the second drive device 53, preventing the sliding round rod 55 from continuing to move towards the circumferential surface of the turntable 54. After the clamping is completed, the device will automatically lock, preventing the silk cake from being unable to be conveyed when the device moves, thus improving the stability of the device during operation.

[0033] A first spring is provided between the square plate 57 and the transmission plate 58. The transmission plate 58 is in contact with the transmission rod 510, and the first spring drives the transmission plate 58 to reset.

[0034] A second spring is provided between the transmission inclined rod 510 and the sliding round rod 55. The transmission inclined rod 510 contacts the limiting inclined block 511, and the second spring drives the transmission inclined rod 510 to reset.

[0035] In this embodiment, during operation: Driving device 1 51 is activated. The movement of driving device 1 51 moves sliding rod 52, which in turn moves driving device 2 53, which in turn moves turntable 54. Then, driving device 3 is activated. The rotation of driving device 3 causes turntable 54 to rotate. When turntable 54 rotates clockwise, it causes the arc-shaped groove to rotate, which in turn causes sliding rod 55 to move towards the circumference of turntable 54. The movement of sliding rod 55 causes fixed plate 56 to move, which in turn causes transmission plate 58 to move, which in turn causes rubber block 59 to move towards the inner wall of the yarn cake. The rubber block 59 then contacts the inner wall of the yarn cake's I-beam wheel, allowing the device to move by contacting the inner wall of the I-beam wheel during picking and placing. The device contacts the wall and removes the yarn cake from the inside by supporting it from the inside. This prevents damage to the fibers when removing it from the outside by contact with the fibers wrapped around the outer wall, thus improving the protection of the yarn cake. After the rubber block 59 contacts the yarn cake, as the fixed plate 56 continues to move towards the transmission plate 58, the movement of the fixed plate 56 will drive the transmission inclined rod 510 to move towards the transmission plate 58. The transmission plate 58 contacts the transmission inclined rod 510 and pushes the transmission inclined rod 510 to move away from the first spring. The movement of the transmission inclined rod 510 will contact the limiting inclined block 511, preventing the sliding round rod 55 from continuing to move towards the circumference of the turntable 54. This allows the device to automatically lock after clamping, preventing it from loosening during device movement and causing the yarn cake to fail to be conveyed, thus improving the stability of the device during operation.

[0036] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the top of the base plate 1 is provided with a protective device for protecting the silk cake and a slowing device for limiting the moving speed of the sliding rod 52. The protective device includes: a collar 61, a transmission vertical rod 62, a sliding column 63, an arc-shaped rod 64, an arc-shaped block 65, an electric push rod 66, a fixed seat 67, a fixed sleeve 68, a triangular block 69, a positioning rod 610, and a positioning block 611. The collar 61 is rotatably mounted on the circumferential surface of the sliding rod 55. The sliding column 63 is slidably mounted on the surface of the second drive device 53. The arc-shaped rod 64 is fixedly mounted on the circumferential surface of the sliding column 63. One end of the transmission vertical rod 62 is fixedly mounted on the circumferential surface of the collar 61, and the other end of the transmission vertical rod 62 is fixedly mounted on the surface of the arc-shaped rod 64. The arc-shaped block 65 is fixedly mounted on the circumferential surface of the sliding column 63. The electric push rod 66 is fixedly mounted on the circumferential surface of the sliding column 63. Installed on the top of drive unit 51, the output end of electric push rod 66 is fixedly mounted with connecting rod 612. Connecting rod 612 is fixedly mounted on the surface of sliding rod 52. Fixed seat 67 is fixedly mounted on the top of drive unit 53. Fixed sleeve rod 68 is fixedly mounted on the inner wall of fixed seat 67. Positioning rod 610 is slidably mounted on the inner wall of fixed sleeve rod 68. Triangular block 69 is fixedly mounted on the inner wall of positioning rod 610 to protect the silk cake and prevent it from being scratched when moving. Positioning block 611 is slidably mounted on the inner wall of fixed sleeve rod 68. Positioning block 611 is fixedly connected to positioning rod 610 so that when the silk cake and the shelf 3 are intertwined, positioning block 611 will limit fixed sleeve rod 68, so that the output end of electric push rod 66 cannot continue to move, preventing excessive pulling from causing the silk cake fibers to break and the silk cake to loosen, thus improving the practicality of the device.

[0037] The arc block 65 contacts the triangular block 69, and a No. 3 spring is provided between the positioning block 611 and the fixed sleeve rod 68. The No. 3 spring drives the positioning block 611 to reset.

[0038] The slowing device includes a hollow box 71, a spring 72, a sliding plate 73, a limiting plate 74, and a friction block 75. The hollow box 71 is fixedly installed on the top of the drive device 51. The spring 72 is fixedly installed on the side of the connecting rod 612 near the hollow box 71. The sliding plate 73 is slidably installed on the inner wall of the hollow box 71. The limiting plate 74 is fixedly installed on the surface of the sliding plate 73. The friction block 75 is slidably installed on the inner wall of the hollow box 71. This device prevents the positioning block 611 from colliding with the fixed sleeve rod 68 due to excessive initial speed when the yarn cake moves, thus preventing overload due to excessive resistance when the output end of the electric push rod 66 moves in the opposite direction, thereby improving the protection effect of the device.

[0039] The slowing device also includes: two clamping plates 76, an L-shaped plate 77, a rotating rod 78, a rotating rod 79, and a one-way plate 710. Both clamping plates 76 are fixedly installed on the inner wall of the hollow box 71. The L-shaped plate 77 is rotatably installed between the two clamping plates 76. The rotating rod 78 is fixedly installed on the output end of the electric push rod 66. The rotating rod 79 is rotatably installed on the surface of the rotating rod 78. The one-way plate 710 is fixedly installed on the side of the rotating rod 78 near the friction block 75, so that the device returns to its initial state and improves the practicality of the device.

[0040] A No. 4 spring is installed between the friction block 75 and the hollow box 71. The L-shaped plate 77 contacts the rotating rod 79, and the friction block 75 is reset by the No. 4 spring.

[0041] In this embodiment, during operation: the movement of the sliding rod 55 causes the collar 61 to move upwards, which in turn causes the transmission vertical rod 62 to move upwards. The movement of the transmission vertical rod 62 causes the arc-shaped rod 64 to move upwards, which in turn causes the sliding column 63 to move upwards. The movement of the sliding column 63 causes the arc-shaped block 65 to move upwards, and the arc-shaped block 65 contacts the triangular block 69. The movement of the arc-shaped block 65 causes the triangular block 69 to move away from the fixed seat 67. The movement of the fixed seat 67 causes the positioning rod 610 to move towards the wire cake, and the positioning rod 610 contacts the wire cake, protecting it from scratches during movement. The electric push rod 66 is activated, and its movement causes the connecting rod 612 to move, which in turn causes the sliding rod 612 to move. The moving rod 52 moves away from the silk cake. The movement of the sliding rod 52 will drive the second drive device 53 to move away from the silk cake. The movement of the second drive device 53 will drive the fixed seat 67 to move away from the silk cake. The movement of the fixed seat 67 will drive the fixed sleeve rod 68 to move away from the positioning rod 610. When the silk cake is entangled with other silk cakes or gets caught on the shelf 3, the fixed sleeve rod 68 will contact the positioning block 611. The fixed sleeve rod 68 is blocked by the positioning block 611, preventing it from moving further. When the silk cake is entangled with the shelf 3, the positioning block 611 will limit the fixed sleeve rod 68, preventing the output end of the electric push rod 66 from moving further. This prevents excessive pulling from causing the silk cake fibers to break and the silk cake to loosen, thus improving the practicality of the device.

[0042] The movement of connecting rod 612 causes spring 72 to move towards hollow box 71. Spring 72 then contacts friction block 75, generating friction and reducing the speed of the output end of electric push rod 66. This prevents excessive initial speed during the movement of the silk cake from causing collision and damage between positioning block 611 and fixed sleeve rod 68. As spring 72 continues to move, it contacts sliding plate 73 and pushes it away from friction block 75. Sliding plate 73's movement causes limit plate 74 to move. After limit plate 74 moves, it no longer contacts friction block 75. Friction block 75 is then reset by spring number four, causing friction block 75 to move away from spring 72. After moving, friction block 75 no longer contacts spring 72. The contact eliminates friction and slows down the movement, preventing overload due to excessive resistance when the output end of the electric push rod 66 moves in the opposite direction, thus improving the protection of the device. The movement of the output end of the electric push rod 66 will cause the first rotating rod 78 to move away from the sliding plate 73. The movement of the first rotating rod 78 will cause the second rotating rod 79 to move. The second rotating rod 79 will contact the L-shaped plate 77. The second rotating rod 79 is blocked by the one-way plate 710, preventing it from rotating in the direction of the one-way plate 710. The movement of the second rotating rod 79 will push the L-shaped plate 77 to rotate. The rotation of the L-shaped plate 77 will cause the friction block 75 to move. After the friction block 75 moves, it will be repositioned by the limiting plate 74, so that the device returns to its initial state and improves the practicality of the device.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
