Description

Technical Field

[0001] This invention relates to the field of cargo storage technology, specifically to a CNC shelving system. Background Technology

[0002] A shelving unit consists of uprights, beams, and shelves, and is a three-dimensional, frame-like device used for storing goods. In existing technology, shelving units are generally fixed structures. Shelves should not be too deep, and the spacing between shelves should not be too narrow. Excessively deep shelves and / or narrow spacing between shelves can lead to difficulties in retrieving and placing goods. Summary of the Invention

[0003] The present invention aims to provide a CNC shelving system that can effectively solve the problem of difficulty in picking and placing goods.

[0004] To address the aforementioned technical problems, the present invention provides the following technical solution: This invention provides a CNC shelving unit, comprising: a frame body, on which two gantry gates are rotatably connected; and multiple second shelves are stacked within the frame body. A second motor is located at the top center of the frame body, and transmission components are located on both sides of the frame body, with the second motor and the transmission components being drive-connected. The gantry gates are equipped with lifting components and shelf-picking / placing components, which are drive-connected when the gantry gates are open. The lifting components can drive the shelf-picking / placing components to move up and down, and the shelf-picking / placing components can pick up the second shelves and place them onto the two gantry gates or into the frame body.

[0005] By adopting the above technical solution, the lifting component can be connected to the transmission component after the two gantry gates are opened. The rotation of the second motor's drive end moves the lifting component up and down via the transmission component to determine which second shelf to retrieve. Then, the shelf-mounting component retrieves the corresponding second shelf onto the two gantry gates, which support the second shelf, allowing workers to retrieve and place goods. Finally, the shelf-mounting component places the second shelf back into the rack, completing the entire retrieval and placement process. In this process, since the required second shelf has already been retrieved, workers can retrieve and place goods more conveniently, without being limited by the depth of the second shelf or the obstruction of two adjacent second shelves, thus effectively solving the problem of difficult retrieval and placement.

[0006] Optionally, the transmission component includes a transmission shaft, a third sprocket, a splined sleeve, and a first cylinder; the transmission shaft is rotatably connected to the frame, the third sprocket is coaxially fixedly connected to one end of the transmission shaft, the splined sleeve is axially slidably connected to the other end of the transmission shaft, the first cylinder is mounted on the frame and its telescopic end is fixedly connected to the splined sleeve; the splined sleeve can be transmitted to the lifting component; a fourth sprocket is coaxially fixedly connected to the drive end of the second motor, a second chain is sleeved on the fourth sprocket, and the second chain is also sleeved on the third sprocket.

[0007] By adopting the above technical solution, when the telescopic end of the first cylinder extends, the spline sleeve can achieve a transmission connection with the lifting component. When the drive end of the second motor rotates, the fourth sprocket rotates coaxially with the drive end of the second motor. Driven by the second chain, the third sprocket drives the transmission shaft to rotate, thereby driving the spline sleeve to rotate, thus realizing the lifting control of the lifting component.

[0008] Optionally, the lifting component includes a rotating shaft, a first fixed sprocket, a second fixed sprocket, a first moving sprocket, a second moving sprocket, and a third chain; the rotating shaft is rotatably connected to the top of the gantry, one end of the rotating shaft has a spline, and the spline sleeve can be splined to the rotating shaft; the first fixed sprocket is coaxially fixedly connected to the rotating shaft, the second fixed sprocket is rotatably connected to the bottom of the gantry, the first moving sprocket and the second moving sprocket are fixed by a locking seat, and the shelf loading and unloading component is disposed on the locking seat; one end of the third chain is fixed to the bottom of the gantry, and after sequentially being engaged and reversed by the second moving sprocket, the second fixed sprocket, the first fixed sprocket, the first fixed sprocket, and the first moving sprocket, the other end is fixed to the top of the gantry.

[0009] By adopting the above technical solution, when the rotating shaft rotates, the first fixed sprocket, the second fixed sprocket, the first moving sprocket, and the second moving sprocket rotate accordingly. The first moving sprocket and the second moving sprocket are limited by the locking seat and can move up or down synchronously, thereby realizing the height adjustment of the shelf loading and unloading parts.

[0010] Optionally, the shelf-loading component includes a long strip seat, a third motor, a fifth sprocket, a sixth sprocket, a fourth chain, a first drag block, and multiple first rollers; the long strip seat is mounted on a locking seat, the third motor is mounted on one end of the long strip seat, the fifth sprocket is coaxially fixedly connected to the drive end of the third motor, and the sixth sprocket is rotatably connected to the other end of the long strip seat; one end of the fourth chain is sleeved on the fifth sprocket, and the other end is sleeved on the sixth sprocket; the first drag block is mounted on the fourth chain and is capable of picking up the second shelf onto the two gantry gates or placing it into the frame.

[0011] By adopting the above technical solution, when the drive end of the third motor rotates, the fifth sprocket rotates coaxially with the drive end of the third motor, and drives the sixth sprocket to rotate via the fourth chain. At this time, the first drag block on the fourth chain moves, and the first drag block can drag the second layer plate onto the long strip seat on the gantry for easy loading and unloading of goods. When the drive end of the third motor rotates in the opposite direction, the first drag block can drag the second layer plate on the long strip seat onto the support base.

[0012] Optionally, a support bolt is vertically threaded to the bottom of the free end of the gantry, a rotating handle is coaxially connected to the top of the support bolt, and the bottom of the support bolt can be inserted into a slotted plate installed on the ground.

[0013] By adopting the above technical solution, when the rotating handle is turned, the handle can rotate coaxially with the support bolt, causing the support bolt to move downward. The bottom of the support bolt is inserted into the slot plate, thereby supporting the gantry. When the support bolt moves upward, the gantry can rotate.

[0014] Optionally, gantry rotating components are respectively provided on both sides of the frame. Each gantry rotating component includes a first rotating frame, a second rotating frame, a mounting plate, a threaded shaft, a threaded sleeve, a first motor, a first reversing gearbox, and a first chain. The first rotating frame is hinged to one side of the frame, the second rotating frame is rotatably mounted on the gantry, the mounting plate is fixedly mounted on the first rotating frame, the threaded shaft is threaded through the mounting plate and the threaded sleeve, and one end is hinged to the gantry through the second rotating frame. The threaded shaft is fixedly connected to the second rotating frame and can drive the gantry to rotate around its rotational connection point with the frame. The first reversing gearbox is mounted on the mounting plate, and the first motor, the first reversing gearbox, and the threaded sleeve are connected in a transmission manner.

[0015] By adopting the above technical solution, when the drive end of the first motor rotates, the first reversing gearbox drives the threaded sleeve to rotate through the first chain. At this time, the first rotating frame and the second rotating frame rotate, and the threaded sleeve drives the threaded shaft to extend or retract toward the gantry, thereby realizing the rotation of the gantry.

[0016] Optionally, the second shelf is mounted on the frame by a support member, which includes a support base, a groove plate, a second drag block, and a plurality of second rollers; the support base is mounted on the frame, the plurality of second rollers are mounted on the support base, the groove plate is slidably connected to the plurality of second rollers, the second shelf is inserted into the groove plate, and the second drag block is mounted on the support base and can abut against the first drag block.

[0017] By adopting the above technical solution, the second plate can be placed on two support seats through two sliding groove plates, and when the first drag block and the second drag block abut, the first drag block can drag the groove plate out or in.

[0018] Optionally, multiple first-layer plates are stacked within the frame via support members, with adjacent first-layer plates and second-layer plates having the same height. Transfer components for moving the first-layer plates to the positions of the second-layer plates are respectively provided on both sides of the frame. Each transfer component includes a fourth motor, a second reversing gearbox, a seventh sprocket, an eighth sprocket, a fifth chain, a drive shaft, a driven shaft, and multiple clutches. The second reversing gearbox is mounted on the frame. The drive shaft and driven shaft are vertically rotatably connected to the frame. The drive end of the fourth motor is coaxially connected to the input end of the second reversing gearbox. The seventh sprocket is coaxially fixedly connected to the output end of the second reversing gearbox. The eighth sprocket is coaxially fixedly connected to the drive shaft. The two ends of the fifth chain are respectively sleeved on the seventh and eighth sprockets.

[0019] By adopting the above technical solution, when the drive end of the fourth motor rotates, the seventh sprocket can drive the eighth sprocket to rotate through the transmission of the second reversing gearbox. The seventh sprocket drives the drive shaft to rotate, and the drive shaft is connected to the driven shaft through the clutch, thereby controlling the transfer of any one or more first layer plates to the position of the second layer plate.

[0020] Optionally, the clutch includes a sliding shaft, a fixed shaft, a return spring, a ninth sprocket, a tenth sprocket, a sixth chain, a second cylinder, an abutment roller, and a third drag block; the sliding shaft is slidably sleeved on the drive shaft, the fixed shaft is coaxially rotatably connected to the drive shaft, the return spring is sleeved on the drive shaft and its two ends abut against the sliding shaft and the fixed shaft respectively, the second cylinder is mounted on the drive shaft, the abutment roller is mounted on the telescopic end of the second cylinder, the ninth sprocket is coaxially fixedly connected to the fixed shaft, the tenth sprocket is coaxially fixedly connected to the driven shaft, the two ends of the sixth chain are respectively sleeved on the ninth sprocket and the tenth sprocket, and the third drag block is disposed on the sixth chain and can abut against the second drag block.

[0021] By adopting the above technical solution, when the telescopic end of the second cylinder extends, the abutting roller abuts against the sliding shaft, causing the sliding shaft to move downward and connect with the fixed shaft via a spline. At this time, the drive shaft drives the fixed shaft to rotate coaxially through the sliding shaft. The ninth sprocket on the fixed shaft drives the tenth sprocket to rotate through the sixth chain, and the tenth sprocket drives the driven shaft to rotate. The third drag block on the sixth chain moves and abuts against the second drag block, thereby dragging the first layer on the support seat to the position of the second layer plate, so that the first drag block on the fourth chain can move and abut against the second drag block, thereby dragging the first layer plate on the support seat onto the long strip seat on the gantry for easy loading and unloading. When the telescopic end of the second cylinder retracts, the return spring drives the sliding shaft to move upward, separating the sliding shaft and the fixed shaft. At this time, the rotation of the drive shaft cannot drive the rotation of the fixed shaft through the sliding shaft, that is, the first layer plate cannot be moved. By controlling the engagement and disengagement of the clutch, the first layer plate of different layers can be moved to the position of the second layer plate. Correspondingly, the first layer plate located at the position of the second layer plate can also be moved back to the position of the first layer plate via the transfer component.

[0022] Optionally, the frame and / or gantry is provided with a brake to prevent the shelf from moving. The brake includes a third cylinder, a brake block, two guide shafts, and two connecting springs. The two guide shafts are arranged side by side on opposite sides of the third cylinder. The brake block is slidably connected to the two guide shafts. The two connecting springs are respectively sleeved on the two guide shafts and their ends are respectively fixedly connected to the third cylinder and the brake block.

[0023] By adopting the above technical solution, when the third cylinder is energized, its telescopic end retracts, compressing the connecting spring, and braking does not occur. When the power is off, the connecting spring is no longer under the force of the third cylinder, returns to its original position, and the brake block slides away from the third cylinder, allowing it to abut against the first or second plate, thus achieving braking.

[0024] In summary, the present invention has at least the following beneficial technical effects: This CNC shelving unit can remove the corresponding shelf when picking up or placing goods, which can effectively avoid the difficulty of picking up or placing goods caused by shelves that are too deep or the spacing between shelves is too narrow, thus improving the convenience of picking up and placing goods.

[0034] This embodiment provides a CNC shelving unit.

[0035] refer to Figure 1 and Figure 2 A CNC shelving unit includes: a frame 1, two gantry gates 2, multiple first shelf panels 3, and multiple second shelf panels 4.

[0036] The frame 1 is a three-dimensional frame, and two gantry gates 2 are respectively hinged to the two sides of the frame 1. The gantry gates 2 can be rotated to fit the loading and unloading side of the frame 1, or they can be rotated to open the loading and unloading side of the frame 1.

[0037] Multiple first-layer plates 3 are horizontally stacked across the side of the rack 1 away from the side for picking up and placing goods, and multiple second-layer plates 4 are horizontally stacked across the side of the rack 1 closer to the side for picking up and placing goods. The number of first-layer plates 3 and second-layer plates 4 is the same, and the first-layer plates 3 and second-layer plates 4 are arranged adjacent to each other at the same height.

[0038] Reference Figure 3 The bottom of the free end of the gantry 2 is vertically threaded with a support bolt 5 via a bracket. A rotating handle 6 is coaxially connected to the top of the support bolt 5. The bottom of the support bolt 5 can be inserted into a slotted plate 7, which is mounted on the ground. When the rotating handle 6 is rotated, it causes the support bolt 5 to rotate coaxially and move downwards, inserting its bottom into the slotted plate 7, thus supporting the gantry 2. When the support bolt 5 moves upwards, the gantry 2 can rotate.

[0039] refer to Figure 2 and Figure 4The frame 1 has gantry rotating components installed on its two outer walls. Each gantry rotating component includes a first rotating frame 8, a second rotating frame 9, a mounting plate 10, a threaded shaft 11, a threaded sleeve 12, a first motor 13, a first reversing gearbox 14, and a first chain 15. The first rotating frame 8 is hinged to one side of the frame 1, the second rotating frame 9 is rotatably mounted on the gantry 2, and the mounting plate 10 is fixedly mounted on the first rotating frame 8. The threaded shaft 11 is threaded through the mounting plate 10 and the threaded sleeve 12, and its right end is fixedly connected to the second rotating frame 9. The right end of the threaded shaft 11 is hinged to the gantry 2 via the second rotating frame 9. The rotational connection point between the gantry 2 and the frame 1 is located at the rear of the left end of the gantry 2, and the rotational connection point between the gantry 2 and the second rotating frame 9 is located at the front of the left end of the gantry 2. The first reversing gearbox 14 is mounted on the mounting plate 10, and the drive end of the first motor 13 and the input end of the first reversing gearbox 14 are coaxially connected. The first sprocket 16 is coaxially sleeved at the output end of the first reversing gearbox 14, and the second sprocket 17 is integrally formed in the circumferential direction of the threaded sleeve 12. The first chain 15 is sleeved on the first sprocket 16 and the second sprocket 17.

[0040] When the drive end of the first motor 13 rotates, the first reversing gearbox 14 drives the threaded sleeve 12 to rotate via the first chain 15. At this time, the first rotating frame 8 and the second rotating frame 9 rotate, and the threaded sleeve 12 drives the threaded shaft 11 to extend or retract toward the gantry 2, thereby realizing the rotation of the gantry 2. Please refer to [link / reference]. Figure 4 When the threaded shaft 11 extends to the right, it drives the gantry 2 to rotate around the rotation connection point between the gantry 2 and the frame 1 via the second rotating bracket 9. During the rotation of the gantry 2, the first rotating bracket 8 located on the left side of the threaded shaft 11 deflects synchronously with the threaded shaft 11. The first rotating bracket 8 rotates around the rotation connection point with the frame 1, and the second rotating bracket 9 rotates relative to the gantry 2 to adapt to the movement of the threaded shaft 11. The threaded shaft 11 can smoothly drive the gantry 2 to rotate around the rotation point with the frame 1.

[0041] refer to Figure 5 A second motor 18 is installed in the top middle section of the frame 1 near the side for picking up and placing goods. Transmission components are respectively installed on both sides of the frame 1, and the second motor 18 and the transmission components are connected for transmission. Lifting components and shelf picking components are respectively installed on the two gantry gates 2. The lifting components and transmission components are connected for transmission when the gantry gates 2 are opened. The lifting components can drive the shelf picking components to move up and down, and the shelf picking components can pick up or place the first shelf 3 or the second shelf 4.

[0042] refer to Figure 4 and Figure 5The transmission components include a drive shaft 19, a third sprocket 20, a splined sleeve 21, and two first cylinders 22. The drive shaft 19 is rotatably connected to the frame 1, the third sprocket 20 is coaxially fixedly connected to one end of the drive shaft 19, and the splined sleeve 21 is axially slidably connected to the other end of the drive shaft 19. The two first cylinders 22 are mounted side by side on the frame 1, and the splined sleeve 21 is located between the two first cylinders 22, with the telescopic ends of the first cylinders 22 fixedly connected to the splined sleeve 21.

[0043] When the telescopic end of the first cylinder 22 extends, the splined sleeve 21 can achieve a transmission connection with the lifting component. A fourth sprocket 23 is coaxially fixedly connected to the drive end of the second motor 18. A second chain 24 is sleeved on the fourth sprocket 23, and the second chain 24 is also sleeved on the third sprocket 20. When the drive end of the second motor 18 rotates, the fourth sprocket 23 rotates coaxially with the drive end of the second motor 18. Driven by the second chain 24, the third sprocket 20 drives the transmission shaft 19 to rotate, thereby driving the splined sleeve 21 to rotate.

[0044] refer to Figure 4 and Figure 5 The lifting mechanism includes a rotating shaft 25, two first fixed sprockets 26, two second fixed sprockets 27, two first moving sprockets 28, two second moving sprockets 29, and two third chains 30. The rotating shaft 25 is horizontally rotatably connected to the top of the gantry 2. One end of the rotating shaft 25 near the hinged end of the gantry 2 has a spline, allowing the splined sleeve 21 to spline into the rotating shaft 25 when the telescopic end of the first cylinder 22 extends. The two first fixed sprockets 26, two second fixed sprockets 27, two first moving sprockets 28, two second moving sprockets 29, and two third chains 30 are divided into two sprocket groups. Each sprocket group includes one first fixed sprocket 26, one second fixed sprocket 27, one first moving sprocket 28, one second moving sprocket 29, and one third chain 30.

[0045] The first fixed sprocket 26 is coaxially fixedly connected to the rotating shaft 25, and the second fixed sprocket 27 is rotatably connected to the bottom of the gantry 2. The first moving sprocket 28 and the second moving sprocket 29 are fixed by a locking seat 31, and the shelf loading and unloading device is set on the locking seat 31, with the first moving sprocket 28 above the second moving sprocket 29. The first fixed sprocket 26, the second fixed sprocket 27, the first moving sprocket 28, and the second moving sprocket 29 are all engaged with the third chain 30. One end of the third chain 30 is fixed to the bottom of the gantry 2, and after being engaged and reversed by the second moving sprocket 29, the second fixed sprocket 27, the first fixed sprocket 26, the first fixed sprocket 26, and the first moving sprocket 28, the other end is fixed to the top of the gantry 2.

[0046] When the rotating shaft 25 rotates, the two first fixed sprockets 26, the two second fixed sprockets 27, the two first moving sprockets 28, and the two second moving sprockets 29 rotate accordingly. The first moving sprockets 28 and the second moving sprockets 29 are limited by the locking seat 31 and can move up or down synchronously, thereby realizing the height adjustment of the shelf loading and unloading parts.

[0047] refer to Figure 6 The shelf loading and unloading mechanism includes a long strip base 32, a third motor 33, a fifth sprocket 34, a sixth sprocket 35, a fourth chain 36, a first drag block 37, and multiple first rollers 38. The long strip base 32 is horizontally fixedly connected to the locking seat 31. The third motor 33 is fixedly connected to one end of the long strip base 32 via a guide bracket. The fifth sprocket 34 is coaxially fixedly connected to the drive end of the third motor 33. The sixth sprocket 35 is rotatably connected to the other end of the long strip base 32 via a bracket. One end of the fourth chain 36 is sleeved on the fifth sprocket 34, and the other end is sleeved on the sixth sprocket 35.

[0048] The first drag block 37 can be one or more. The first drag block 37 is fixedly connected to the side of the fourth chain 36. The first drag block 37 is used to drag the first layer plate 3 or the second layer plate 4 from the frame 1 to the gantry 2, or from the gantry 2 into the frame 1. Multiple first rollers 38 are installed in a straight line at equal intervals along the length of the long strip 32. When the first layer plate 3 or the second layer plate 4 is transferred to the long strip 32, the first rollers 38 can provide rolling support for the first layer plate 3 or the second layer plate 4.

[0049] Meanwhile, a guide roller 39 is rotatably connected to the guide bracket, and a guide groove is vertically opened at the free end of the gantry 2. The guide roller 39 is located in the guide groove, thereby guiding the up and down movement of the shelf pick-up and drop parts and improving stability.

[0050] refer to Figure 2 and Figure 6 Both the first shelf 3 and the second shelf 4 are mounted on the frame 1 via support members. The support members include a support base 40, a slotted plate 41, a second drag block 42, and multiple second rollers 43. The support base 40 is welded to the inner wall of the frame 1, and the multiple second rollers 43 are installed on the support base 40 at equal intervals along its length. The slotted plate 41 has a first slot and a second slot, the opening directions of which are perpendicular to each other. The slotted plate 41 is slidably connected to the support base 40, specifically, the multiple second rollers 43 are located within the first slot, providing sliding support for the slotted plate 41. The first shelf 3 or the second shelf 4 is inserted into the second slot. The second drag block 42 is welded to the side of the support base 40 near the bracket and is located near the loading / unloading side; the second drag block 42 can abut against the first drag block 37.

[0051] When the drive end of the third motor 33 rotates, the fifth sprocket 34 rotates coaxially with the drive end of the third motor 33, and drives the sixth sprocket 35 to rotate via the fourth chain 36. At this time, the first drag block 37 on the fourth chain 36 moves and abuts the second drag block 42, thereby dragging the first shelf 3 or the second shelf 4 on the support base 40 onto the long shelf 32 on the gantry 2 for easy loading and unloading of goods. Correspondingly, when the drive end of the third motor 33 rotates in the opposite direction, it can drag the first shelf 3 or the second shelf 4 on the long shelf 32 onto the support base 40. How to move the first shelf 3 to the position of the second shelf 4 will be described below.

[0052] refer to Figure 2 and Figure 7 The frame 1 has transfer components on both sides for moving the first shelf 3 to the position of the second shelf 4. The transfer components include a fourth motor 44, a second reversing gearbox 45, a seventh sprocket 46, an eighth sprocket 47, a fifth chain 48, a drive shaft 49, a driven shaft 50, and multiple clutches. The second reversing gearbox 45 is mounted on the top of the middle section of one side of the frame 1. The drive shaft 49 is vertically rotatably connected to one side of the frame 1, and is located between the first shelf 3 and the second shelf 4. The driven shaft 50 is vertically rotatably connected to one side of the frame 1, and is located near the side of the frame 1 closest to the loading / unloading area. The drive end of the fourth motor 44 is coaxially connected to the input end of the second reversing gearbox 45, and the seventh sprocket 46 is coaxially fixedly connected to the output end of the second reversing gearbox 45. The eighth sprocket 47 is coaxially fixedly connected to the drive shaft 49, and the two ends of the fifth chain 48 are respectively sleeved on the seventh sprocket 46 and the eighth sprocket 47.

[0053] When the drive end of the fourth motor 44 rotates, the seventh sprocket 46 can drive the eighth sprocket 47 to rotate through the fifth chain 48 via the transmission of the second reversing gearbox 45. The seventh sprocket 46 drives the drive shaft 49 to rotate. The drive shaft 49 is connected to the driven shaft 50 through the clutch, thereby controlling the transfer of any one or more first layer plates 3.

[0054] refer to Figure 7The number of clutches is the same as the number of first layer plates 3, with each clutch corresponding to one first layer plate 3. Each clutch includes a sliding shaft 51, a fixed shaft 52, a return spring 53, a ninth sprocket 54, a tenth sprocket 55, a sixth chain 56, two second cylinders 57, two abutting rollers 58, and at least one third drag block 59. The sliding shaft 51 is slidably mounted on the drive shaft 49 and cannot rotate circumferentially; when the drive shaft 49 rotates, the sliding shaft 51 rotates coaxially with it. The fixed shaft 52 is coaxially rotatably connected to the drive shaft 49, and the sliding shaft 51 of a single clutch is above the fixed shaft 52. The return spring 53 is mounted on the drive shaft 49, with its two ends pressing against the sliding shaft 51 and the fixed shaft 52 respectively. The two second cylinders 57 are respectively installed on opposite sides of the drive shaft 49, and the two abutting rollers 58 are respectively installed on the extension and retraction ends of the two second cylinders 57. The ninth sprocket 54 is coaxially and fixedly connected to the fixed shaft 52, and the tenth sprocket 55 is coaxially and fixedly connected to the driven shaft 50. The two ends of the sixth chain 56 are respectively sleeved on the ninth sprocket 54 and the tenth sprocket 55. The third drag block 59 is fixedly connected to the sixth chain 56, and the third drag block 59 can abut against the second drag block 42.

[0055] When the telescopic end of the second cylinder 57 extends, the abutment roller 58 abuts against the sliding shaft 51, causing the sliding shaft 51 to move downward and spline-connect with the fixed shaft 52. At this time, the drive shaft 49 drives the fixed shaft 52 to rotate coaxially via the sliding shaft 51. The ninth sprocket 54 on the fixed shaft 52 drives the tenth sprocket 55 to rotate via the sixth chain 56. The tenth sprocket 55 drives the driven shaft 50 to rotate. The third drag block 59 on the sixth chain 56 moves and abuts against the second drag block 42, thereby dragging the first shelf 3 on the support base 40 to the position of the second shelf 4, so that the first drag block 37 on the fourth chain 36 can move and abut against the second drag block 42, thereby dragging the first shelf 3 on the support base 40 onto the long strip seat 32 on the gantry 2 for easy loading and unloading of goods. It should be understood that in this step, the second shelf 4 needs to be removed from the frame 1 and the gantry 2. When the telescopic end of the second cylinder 57 retracts, the return spring 53 drives the sliding shaft 51 to move upward, separating the sliding shaft 51 from the fixed shaft 52. At this time, the rotation of the drive shaft 49 cannot drive the rotation of the fixed shaft 52 through the sliding shaft 51, that is, the first layer plate 3 cannot be moved. Through the above design, by controlling the engagement and disengagement of the clutch, the first layer plate 3 of different layers can be moved to the position of the second layer plate 4. Correspondingly, the first layer plate 3 at the position of the second layer plate 4 can also be moved back to the position of the first layer plate 3 by the transfer component.

[0056] In an optional embodiment of this application, brake components can be installed on both the frame 1 and the gantry 2 to prevent the shelves from moving. In this embodiment, multiple brake components are provided on both sides of the frame 1, each brake component corresponding to a first shelf 3 or a second shelf 4; brake components are also provided on the long support 32.

[0057] refer to Figure 6 The braking system includes a third cylinder 60, a brake block 61, two guide shafts 62, and two connecting springs 63. The two guide shafts 62 are fixedly connected side-by-side to opposite sides of the third cylinder 60 via brackets. The brake block 61 is slidably connected to the two guide shafts 62 via two lugs on its sides. The two connecting springs 63 are respectively sleeved on the two guide shafts 62, with one end of each spring fixedly connected to the bracket of the third cylinder 60 and the other end fixedly connected to the lug of the brake block 61.

[0058] When the third cylinder 60 is energized, its telescopic end retracts, compressing the connecting spring 63, and braking is not applied. When the power is off, the connecting spring 63 is no longer under the force of the third cylinder 60, and returns to its original position. The brake block 61 slides away from the third cylinder 60, and then abuts against the support seat 40, thereby achieving braking.

[0059] In an optional embodiment of this application, reference is made to Figure 1 A weighing device 64 can also be installed on the ground near the loading / unloading side of the frame 1 to weigh the goods.

[0060] It should be understood that this CNC shelving can also be equipped with alarm systems based on alarm lights and voice devices, as well as detection systems based on sensors, etc., which will not be elaborated here.
