Description

Technical Field

[0001] This invention relates to the field of automated warehouse technology, and more specifically, to a forklift-type rotary table-type automated warehouse and its usage method. Background Technology

[0002] In the automotive manufacturing industry, small single-piece fixtures (such as positioning and clamping fixtures for car doors, fenders, sheet metal parts, etc.) are characterized by large demand, wide variety, and frequent model changes. In order to achieve orderly management and efficient retrieval of such fixtures, various fixtures usually need to be stored in different storage rooms on different floors of the fixture automated warehouse to save workshop floor space and improve space utilization.

[0003] In the existing technology, the transfer and storage of such small single-piece fixtures mainly relies on a forklift-type rotary table fixture automated storage and retrieval system. The core transfer logic is as follows: first, the fixture tray containing the fixture is placed on the double forklift at a low position. After the double forklift is driven by the lifting mechanism to rise to the target high storage layer, the rotary table rotates and drives the fixture tray to the corresponding door position of each storage room on that layer, thereby completing the initial transfer and positioning of the fixture.

[0004] However, the above solutions still have the following problems in actual operation: After the fork arm transports the fixture tray to the location at the entrance of each storage room, the fixture tray needs to go through three steps in sequence to fully enter the storage room: "the fork arm first extends horizontally into the storage room, the fork arm drives the fixture tray to descend so that the fixture tray is no longer in contact with the fork arm lifting surface, and the fork arm then retracts horizontally back into position from the storage room". The entire operation process is redundant and takes a long time, which cannot meet the production needs of the automotive industry where small and medium-sized single-piece fixtures are frequently changed and need to be quickly transferred and stored.

[0005] In view of this, we propose a fork-arm type rotary table type fixture 3D library and its usage method to improve the shortcomings of the prior art. Summary of the Invention

[0006] One of the objectives of this invention is to provide a fork-arm type rotary table fixture storage system, which solves the problem that the fork arm still needs to go through multiple steps to send the fixture into the storage room, resulting in a long time consumption.

[0007] To achieve the above objectives, the fork-arm type turntable type fixture automated storage system includes a pair of lifting guide rails set at one end of the automated storage system. The automated storage system includes multiple storage compartments. Lifting sliders are slidably set on the side of the two lifting guide rails that are close to each other. A base is fixedly connected between the two lifting sliders. A turntable body is rotatably connected to the top of the base.

[0008] A horizontal guide rail is concentrically fixedly connected to the top of the turntable body. A horizontal slide block is slidably provided on the top of the horizontal guide rail. An arc-shaped lever block is fixedly connected to the centrifugal side of the horizontal slide block. Multiple pressure-bearing lever blocks are slidably connected to the periphery of the horizontal guide rail. The distance between the centrifugal end of the arc-shaped lever block and the axis is greater than the distance between the centripetal end of the pressure-bearing lever block and the axis. A fork arm body is provided on the side of the pressure-bearing lever block away from the horizontal guide rail, which is slidably connected to the turntable body. The fork arm body and the pressure-bearing lever block are in contact through an inclined surface. When the arc-shaped lever rotates around the horizontal guide rail, the arc-shaped lever can push the pressure-bearing lever to extend radially outward, causing the fork body to slide relative to the turntable body in the vertical direction, so as to separate the fork body from the clamp support on its top.

[0009] Based on this, multiple drive wheels are rotatably connected inside the horizontal slide, and each drive wheel rolls and fits against the outer wall of the horizontal guide rail.

[0010] One of the drive wheels is coaxially connected to a drive motor on the side away from the horizontal guide rail, and the drive motor is used to provide the driving force for the horizontal slide to slide along the horizontal guide rail.

[0011] Furthermore, the pressure-bearing block includes an arc-shaped portion and a straight portion. The distance from the arc-shaped portion to the axis of the turntable body is less than the distance from the centrifugal end of the arc-shaped block to the axis of the turntable body, that is, the arc-shaped portion is located on the path of the arc-shaped block's rotation.

[0012] With this design, when one of the clamp trays rotates to the entrance of the storage chamber, the power to the drive motor is turned on, causing the drive wheel to rotate. Driven by the friction between the drive wheel and the outer wall of the horizontal guide rail, the horizontal slide slides along the top of the horizontal guide rail. When the arc-shaped lever slides to the vicinity of the clamp tray to be transferred into the storage chamber, the arc-shaped lever slides past the centripetal end of the arc-shaped part of the pressure lever. The arc-shaped lever pushes the arc-shaped part to slide to the centrifugal side by squeezing it, thereby causing the fork arm body to descend and separate from the bottom of the clamp tray, so that the pushing structure of the storage chamber can push the clamp tray into the interior of the storage chamber.

[0013] In another technical solution, the straight part of the pressure-bearing block is slidably connected to the inner wall of the limiting ring seat, and the two opposite sides of the inside of the limiting ring seat are provided with sliding grooves. The two opposite ends of the straight part of the pressure-bearing block are fixedly connected with sliding bolts, and each sliding bolt is slidably connected to the corresponding sliding groove.

[0014] Furthermore, a guide rod is fixedly installed inside the slide groove along the sliding direction of the sliding bolt, and a return spring is sleeved around the guide rod between the sliding bolt and the side wall of the slide groove. The two ends of the return spring that are far apart are respectively in close contact with the sliding bolt and the side wall of the slide groove.

[0015] In this technical solution, when the arc-shaped part of the pressure-bearing block is squeezed by the arc-shaped block, the straight part of the pressure-bearing block drives the sliding bolt to slide in the groove towards the centrifugal direction of the turntable body. During the sliding of the sliding bolt along the guide rod, the return spring stores elastic potential energy due to the compression between the sliding bolt and the side wall of the groove. After the arc-shaped block leaves the vicinity of the arc-shaped part of the pressure-bearing block, the pressure-bearing block loses the squeezing force, and the sliding bolt is reset under the action of the restoring force of the return spring.

[0016] In addition, a number of horizontal push blocks are fixedly connected to the side of the straight part of the pressure-bearing block away from the arc-shaped part, and a horizontal wedge is fixedly connected to the end of the horizontal push block away from the straight part of the pressure-bearing block, with the inclined surface of the horizontal wedge facing downward.

[0017] Furthermore, a lifting wedge is fixedly connected to one end of the fork arm body near the horizontal wedge, with the inclined surface of the lifting wedge facing upwards, and the inclined surface of the horizontal wedge slidingly engaging with the inclined surface of the lifting wedge.

[0018] Several lifting slide rods are fixedly connected to the bottom of the fork arm body. A buffer groove is provided at the bottom of each mounting plate on the top of the turntable body. The end of the lifting slide rod away from the fork arm body is located in the buffer groove.

[0019] Based on the above, a lifting spring shall be provided on the periphery of the lifting slide rod between the top of the mounting plate and the bottom of the fork arm body, and the deformation force of the lifting spring shall be greater than the weight of the clamp support and the clamp inside it.

[0020] As described above, when the horizontal slide block drives the arc-shaped lever to slide along the top of the horizontal guide rail, the arc-shaped lever, by pressing the arc-shaped part of the pressure lever, causes the horizontal wedge to slide horizontally along the centrifugal direction of the turntable body. The inclined surface where the horizontal wedge and the lifting wedge slide and fit together converts the horizontal movement of the horizontal wedge into the vertical movement of the lifting wedge. In other words, the lifting wedge causes the fork arm body to move downward, the fork arm body separates from the bottom of the clamp holder, and the clamp holder is transferred into the storage chamber by the pushing structure inside the storage chamber. During this period, the lifting spring is compressed and stores elastic potential energy. After the horizontal wedge returns to its horizontal position, the fork arm body also returns to its original position under the restoring force of the lifting spring.

[0021] The second objective of this invention is to provide a method for using a forklift-type rotary table-type automated storage and retrieval system, comprising the following steps: S1. After placing the clamp in the clamp holder, place the clamp holder on the top of the fork arm body at a low position, and move the clamp holder from a low position to a high position by sliding the lifting slider along the surface of the lifting guide rail. S2. Start the horizontal slide block to make it rotate the arc-shaped block around the horizontal guide rail. When the arc-shaped block passes near each clamp holder placed on the top of the fork body, the arc-shaped block pushes the pressure block to move horizontally in the radial direction. Since the pressure block and the fork body are in contact through the inclined surface, this contact method converts the horizontal movement of the pressure block into the vertical movement of the fork body. S3. The fork arm body separates from the clamp tray by sliding downwards, while the bottom of the clamp tray remains in contact with the inner bottom wall of the storage chamber, waiting for the push structure inside the storage chamber to push the clamp tray completely into the storage chamber. S4. The fork arm body, separated from the clamp holder, follows the turntable body as it rotates and leaves the current storage chamber entrance, waiting for the next clamp holder to rotate to the new storage chamber entrance, and then repeats the above operation.

[0022] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: When the horizontal slide block drives the arc-shaped lever to slide along the top of the horizontal guide rail, the arc-shaped lever, by pressing the arc-shaped part of the pressure-bearing lever, causes the horizontal wedge to slide horizontally in the centrifugal direction of the turntable body. The inclined surface that slides and fits between the horizontal wedge and the lifting wedge converts the horizontal movement of the horizontal wedge into the vertical movement of the lifting wedge. In other words, the lifting wedge causes the fork arm body to move downward, the fork arm body separates from the bottom of the clamp holder, and the clamp holder is transferred into the storage chamber by the pushing structure inside the storage chamber.

[0023] Through the above operations, each time a clamp tray is transferred, the new clamp tray can be rotated to the entrance of the new storage room simply by rotating the turntable body, thereby meeting the needs of large-scale and multi-type transfer of small automotive clamps.

[0026] 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 a part of the embodiments of the present invention, and not all of the 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.

[0027] Example 1: In the prior art, after the fork arm transports the clamp tray to the location at the entrance of each storage room, the clamp tray needs to go through three steps in sequence to fully enter the storage room: "the fork arm first extends horizontally into the storage room, the fork arm drives the clamp tray to descend so that the clamp tray is no longer in contact with the fork arm lifting surface, and the fork arm then retracts horizontally back into position from the storage room". The entire operation process is redundant and takes a long time, which cannot meet the production needs of the automotive industry where small and medium-sized single-piece clamps are frequently changed and need to be quickly transferred and stored.

[0028] like Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a fork-arm type turntable type fixture automated storage and retrieval system. The fixture automated storage and retrieval system includes a pair of lifting guide rails 110 disposed at one end of the automated storage and retrieval system 100. The automated storage and retrieval system 100 includes multiple storage chambers 101. Lifting sliders 122 are slidably disposed on the side of the two lifting guide rails 110 that are close to each other. A base 121 is fixedly connected between the two lifting sliders 122. A turntable body 120 is rotatably connected to the top of the base 121. A horizontal guide rail 200 is concentrically fixedly connected to the top of the turntable body 120. A horizontal slide block 210 is slidably provided on the top of the horizontal guide rail 200. An arc-shaped lever block 220 is fixedly connected to the centrifugal side of the horizontal slide block 210. Multiple pressure-bearing lever blocks 310 are slidably connected to the periphery of the horizontal guide rail 200. The distance between the centrifugal end of the arc-shaped lever block 220 and the axis is greater than the distance between the centripetal end of the pressure-bearing lever block 310 and the axis. A fork arm body 331 is provided on the side of the pressure-bearing lever block 310 away from the horizontal guide rail 200 and is slidably connected to the turntable body 120. The fork arm body 331 and the pressure-bearing lever block 310 are in contact through an inclined surface. When the arc-shaped lever 220 rotates around the horizontal guide rail 200, the arc-shaped lever 220 can push the pressure-bearing lever 310 to extend radially outward, so that the fork body 331 slides relative to the turntable body 120 in the vertical direction, so that the fork body 331 separates from the clamp support on its top.

[0029] Working principle: After the clamp is placed in the clamp holder, the clamp holder is placed on the top of the fork arm body 331 at a low position. The clamp holder is transferred from a low position to a high position by sliding the lifting slider 122 upward along the surface of the lifting guide rail 110. Then, the horizontal slide 210 is activated to drive the arc-shaped lever 220 to rotate around the horizontal guide rail 200. When the arc-shaped lever 220 passes near each clamp holder placed on the top of the fork body 331, the arc-shaped lever 220 pushes the pressure-bearing lever 310 to move horizontally in the radial direction. Since the pressure-bearing lever 310 and the fork body 331 are in contact through the inclined surface, this contact method converts the horizontal movement of the pressure-bearing lever 310 into the vertical movement of the fork body 331. Therefore, the fork arm body 331 separates from the clamp tray by sliding downwards, while the bottom of the clamp tray remains in contact with the inner bottom wall of the storage chamber 101, waiting for the push structure inside the storage chamber 101 to push the clamp tray completely into the storage chamber 101. This push structure is an inherent structure in the existing automated warehouse 100, which is not shown in the attached drawings and will not be described in detail here.

[0030] The fork arm body 331, separated from the clamp holder, follows the turntable body 120 as it rotates and leaves the current storage chamber 101 entrance, waiting for the next clamp holder to rotate to the new storage chamber 101 entrance, and then repeats the above operation.

[0031] Next, please refer to Figure 3 and Figure 4 Multiple drive wheels 211 are rotatably connected inside the horizontal slide 210, and each drive wheel 211 rolls against the outer wall of the horizontal guide rail 200.

[0032] One of the drive wheels 211 is coaxially connected to a drive motor 212 on the side away from the horizontal guide rail 200. The drive motor 212 is used to provide the driving force for the horizontal slide 210 to slide along the horizontal guide rail 200.

[0033] Furthermore, the pressure-bearing lever 310 includes an arc-shaped portion and a straight portion. The distance from the arc-shaped portion to the axis of the turntable body 120 is less than the distance from the centrifugal end of the arc-shaped lever 220 to the axis of the turntable body 120, that is, the arc-shaped portion is located on the path of rotation of the arc-shaped lever 220.

[0034] It should be noted that when one of the clamp trays rotates to the entrance of the storage chamber 101 to be stored, the power supply of the drive motor 212 is turned on, causing the drive wheel 211 to rotate. Under the driving force of the friction between the drive wheel 211 and the outer wall of the horizontal guide rail 200, the horizontal slide 210 slides along the top of the horizontal guide rail 200. When the arc-shaped lever 220 slides to the vicinity of the clamp tray to be transferred into the storage chamber 101, the arc-shaped lever 220 slides past the centripetal end of the arc-shaped part of the pressure lever 310. The arc-shaped lever 220 pushes the arc-shaped part to slide to the centrifugal side by squeezing it, thereby causing the fork arm body 331 to descend and separate from the bottom of the clamp tray, so that the pushing structure of the storage chamber 101 can push the clamp tray into the interior of the storage chamber 101.

[0035] Through the above operations, each time a clamp tray is transferred, the new clamp tray is simply rotated to the entrance of the new storage chamber 101 by rotating the turntable body 120, thereby meeting the needs of large-scale and multi-type transfer of small clamps for automobiles.

[0036] exist Figure 5 and Figure 6 In the middle, the straight part of the pressure-bearing block 310 is slidably connected to the inner wall of the limiting ring seat 301. The two sides of the limiting ring seat 301 that are far apart are provided with sliding grooves 302. The two ends of the straight part of the pressure-bearing block 310 that are far apart are fixedly connected with sliding bolts 311. Each sliding bolt 311 is slidably connected to the corresponding sliding groove 302.

[0037] Furthermore, a guide rod 303 is fixedly provided inside the slide groove 302 along the sliding direction of the sliding bolt 311. A return spring 304 is sleeved on the periphery of the guide rod 303 between the sliding bolt 311 and the side wall of the slide groove 302. The two ends of the return spring 304 that are far apart are respectively in close contact with the sliding bolt 311 and the side wall of the slide groove 302.

[0038] In other words, when the arc-shaped part of the pressure-bearing block 310 is squeezed by the arc-shaped block 220, the straight part of the pressure-bearing block 310 drives the sliding bolt 311 to slide in the groove 302 toward the centrifugal direction of the turntable body 120. During the process of the sliding bolt 311 sliding along the guide rod 303, the return spring 304 is squeezed by the sliding bolt 311 and the side wall of the groove 302 and stores elastic potential energy. After the arc-shaped block 220 leaves the vicinity of the arc-shaped part of the pressure-bearing block 310, the pressure-bearing block 310 loses the squeezing force, and the sliding bolt 311 is reset under the action of the restoring force of the return spring 304.

[0039] Based on the above explanation, the following will further combine... Figure 7 and Figure 8 Explaining the preferred effect of the arc-shaped lever 220 moving radially along the turntable body 120 to support the pressure lever 310, thereby causing the fork arm body 331 to descend: Several horizontal push blocks 321 are fixedly connected to the side of the straight part of the pressure-bearing push block 310 away from the arc-shaped part. A horizontal wedge block 320 is fixedly connected to the end of the horizontal push block 321 away from the straight part of the pressure-bearing push block 310, with the inclined surface of the horizontal wedge block 320 facing downward.

[0040] Furthermore, a lifting wedge 330 is fixedly connected to one end of the fork arm body 331 near the horizontal wedge 320. The inclined surface of the lifting wedge 330 faces upward, and the inclined surface of the horizontal wedge 320 slides and fits against the inclined surface of the lifting wedge 330.

[0041] Continue reading Figure 8 Several lifting slide rods 332 are fixedly connected to the bottom of the fork arm body 331. The top of the turntable body 120 has a buffer groove 123 at the bottom of each mounting plate 300. The end of the lifting slide rod 332 away from the fork arm body 331 is located in the buffer groove 123.

[0042] Based on the above, a lifting spring 333 shall be provided on the periphery of the lifting slide bar 332 between the top of the mounting plate 300 and the bottom of the fork arm body 331. The deformation elastic force of the lifting spring 333 shall be greater than the weight of the clamp support and the clamp inside it.

[0043] When the horizontal slide block 210 drives the arc-shaped lever 220 to slide along the top of the horizontal guide rail 200, the arc-shaped lever 220, by pressing the arc-shaped part of the pressure-bearing lever 310, causes the horizontal wedge 320 to slide in the centrifugal direction of the turntable body 120 in the horizontal direction. The inclined surface that slides and fits between the horizontal wedge 320 and the lifting wedge 330 converts the horizontal movement of the horizontal wedge 320 into the vertical movement of the lifting wedge 330. That is, the lifting wedge 330 drives the fork body 331 to move downward, and the fork body 331 separates from the bottom of the clamp holder. The clamp holder is transferred into the storage chamber 101 by the pushing structure inside the storage chamber 101. During this period, the lifting spring 333 is compressed and stores elastic potential energy. After the horizontal wedge 320 returns to its horizontal position, the fork body 331 also returns to its position under the restoring force of the lifting spring 333.

[0044] Example 2: This example, based on the content provided in Example 1, aims to provide a method for using a forklift-type rotary table-type automated storage and retrieval system. The specific steps are as follows: S1. Low-level loading and high-level transfer. Place the small single-piece clamps to be stored in the clamp tray, and place the clamp tray on the top of the fork arm body 331 at a low level; activate the lifting slider 122 to slide it upward along the lifting guide rail 110, which will drive the clamp tray on the base 121, the turntable body 120 and the fork arm body 331 to rise together, and transfer the clamp tray from the low level to the entrance of the storage room 101 of the target storage layer of the automated warehouse 100.

[0045] S2. The turntable body 120 is aligned and the arc-shaped lever 220 is activated. The turntable body 120 is rotated to precisely align the fork arm body 331 carrying the clamp holder with the entrance of the target storage chamber 101; the power of the drive motor 212 is turned on, and the drive motor 212 drives the drive wheel 211 to rotate. Under the action of friction, the horizontal slide 210 slides along the horizontal guide rail 200, thereby driving the arc-shaped lever 220 to rotate around the horizontal guide rail 200.

[0046] S3. The fork arm descends and separates from the clamp support. When the arc-shaped lever 220 rotates to the vicinity of the current clamp support, it squeezes the arc-shaped part of the pressure-bearing lever 310, pushing the pressure-bearing lever 310 to move horizontally outward along the turntable body 120. With the help of the inclined surface between the pressure-bearing lever 310 and the fork arm body 331, or the inclined surface of the horizontal wedge 320 and the lifting wedge 330, the horizontal movement of the pressure-bearing lever 310 is converted into the vertical downward movement of the fork arm body 331, so that the fork arm body 331 separates from the clamp support, and the bottom of the clamp support contacts the inner bottom wall of the storage chamber 101.

[0047] S4. Fixture tray storage and mechanism reset. Utilizing the push structure of the storage chamber 101 of the automated warehouse 100, the fixture tray, separated from the fork arm body 331, is completely pushed into the storage chamber 101. The arc-shaped lever 220 continues to rotate away from the pressure lever 310, which is radially reset under the action of the reset spring 304. The fork arm body 331 is vertically reset under the action of the lifting spring 333. The turntable body 120 rotates, causing the reset fork arm body 331 to leave the current storage chamber 101 entrance, waiting for the next fixture tray to be transferred to the new storage chamber 101 entrance. The above steps are repeated to complete the batch fixture transfer and storage.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

The inclined surface of the horizontal wedge (320) faces downward.

8. The fork-arm type rotary table type fixture automated storage system according to claim 7, characterized in that: The fork arm body (331) is fixedly connected to a lifting wedge (330) at one end near the horizontal wedge (320). The inclined surface of the lifting wedge (330) faces upward, and the inclined surface of the horizontal wedge (320) slides and fits against the inclined surface of the lifting wedge (330).

9. The fork-arm type rotary table type fixture automated storage system according to claim 1, characterized in that: The bottom of the fork arm body (331) is fixedly connected with several lifting slide rods (332), and the top of the turntable body (120) is provided with a buffer groove (123) at the bottom of each mounting plate (300). The end of the lifting slide rod (332) away from the fork arm body (331) is located in the buffer groove (123). A lifting spring (333) shall be provided on the periphery of the lifting slide bar (332) between the top of the mounting plate (300) and the bottom of the fork body (331). The deformation elastic force of the lifting spring (333) shall be greater than the weight of the clamp support and the clamp inside it.

10. A method of using a fork-arm type rotary table type fixture automated storage system as described in any one of claims 1-9, characterized in that: Includes the following steps: S1. After placing the clamp in the clamp holder, place the clamp holder on the top of the fork arm body (331) at a low position, and slide the lifting slider (122) upward along the surface of the lifting guide rail (110) to transfer the clamp holder from a low position to a high position. S2. Start the horizontal slide (210) to drive the arc-shaped lever (220) to rotate around the horizontal guide rail (200). When the arc-shaped lever (220) passes near the clamp holder placed on the top of each fork body (331), the arc-shaped lever (220) pushes the pressure-bearing lever (310) to move horizontally in the radial direction. Since the pressure-bearing lever (310) and the fork body (331) are in contact through the inclined surface, this contact method converts the horizontal movement of the pressure-bearing lever (310) into the vertical movement of the fork body (331). S3. The fork arm body (331) separates from the clamp holder by sliding downwards, while the bottom of the clamp holder remains in contact with the inner bottom wall of the storage chamber (101), waiting for the push structure inside the storage chamber (101) to push the clamp holder completely into the storage chamber (101). S4. The fork arm body (331) separated from the clamp holder rotates with the turntable body (120) and leaves the current storage chamber (101) entrance, waiting for the next clamp holder to rotate to the new storage chamber (101) entrance, and then repeats the above operation.
