[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0019] Reference Figure 1 to Figure 6 : The storage rack driving mechanism includes a base 1, a storage rack 3, a driving assembly 2 and a moving assembly 4. The base 1 is provided with a storage rack 3, a driving assembly 2 and a moving assembly 4. There are multiple storage racks 3. The driving assembly 2 and the moving assembly 4 are connected. The moving assembly 4 is arranged below the storage rack 3. The moving assembly 4 includes a first guide rail 42 and a moving bar 41. The first guide rail 42 is fixed on the base 1. The moving bar 41 cooperates with the first guide rail 42. The moving bar 41 is provided with multiple first positioning holes 43 along the length direction. The moving bar 41 is connected with the driving assembly 2. A positioning assembly 30 is provided at the bottom of each storage rack 3. The positioning assembly 30 and the first positioning hole 43 are arranged correspondingly. Among them, the number of storage racks 3 can be increased or decreased according to the actual storage needs. The driving assembly 2 can control the movement of the moving assembly 4, thereby controlling the movement of the corresponding storage rack 3.
[0020] In actual use, shafted plate rollers are placed on both sides of the storage rack to realize the storage of shafted plate rollers. When the shafted plate roller on one of the storage racks 3 needs to be taken out, or the shafted plate roller needs to be placed, the remaining storage racks on one side of the storage rack 3 are moved, so that there is corresponding space for placing or taking out the shafted plate roller, which is convenient for operation.
[0021] The positioning assembly 30 includes a first cylinder 31, such as Figure 3 As shown, the first cylinder 31 is arranged on one side of the storage rack 3 and is arranged vertically. The first cylinder 31 corresponds to the moving bar 41, and the first piston rod 32 of the first cylinder 31 can cooperate with the first positioning hole 43. When the first cylinder 31 cooperates with the first positioning hole 43, the piston rod of the first cylinder 31 moves downward and is inserted into the first positioning hole 43 of the moving bar 41, so that the storage rack 3 is connected to the moving bar 41. After the connection, when the moving bar 41 moves horizontally, it can simultaneously drive the corresponding storage rack 3 to move forward and backward along the guide rail.
[0022] The positioning assembly 30 also includes a second cylinder 33, which is vertically arranged and located on one side of the first cylinder 31. The base 1 is provided with a second positioning hole 51, and there are multiple second positioning holes 51, which are located on one side of the moving bar 41. The multiple second positioning holes 51 are distributed along the length direction of the moving bar 41, and the piston rod of the second cylinder 33 corresponds to the second positioning hole 51. When the piston rod of the second cylinder 33 moves downward, it is inserted into the second positioning hole 51, and at the same time, the piston rod of the first cylinder 31 rises, so that the storage rack 3 can be fixed on the base 1 without moving with the moving bar.
[0023] Preferably, a plurality of fixing seats 5 are provided on one side of the moving assembly 4, referring to Figure 4 and Figure 5 A fixing seat structure is shown, in which the fixing seat 5 is arranged along the length direction of the base 1, wherein the second positioning hole 51 is located on the fixing seat 5. The piston rod of the second cylinder 33 moves downward and is inserted into the through hole 51 of the fixing seat 5, so that when the storage rack 3 is in the storage state, it can be more firmly fixed on the base 1. At the same time, the piston rod of the first cylinder 31 moves upward and disengages from the moving bar 41, so that when the moving bar 41 drives other storage racks 3 to move, the storage rack 3 disengaged from the moving bar 41 is still fixed on the fixing seat 5 and is not affected by the movement of the moving bar 41.
[0024] During the movement of the storage rack 3, in order to facilitate the installation of the first cylinder and the second cylinder, mounting racks 35 are provided on both sides of the storage rack 3, and mounting cavities 351 are provided in the mounting racks 35. The cylinder bodies of the first cylinder 31 and the second cylinder 33 are fixed in the mounting cavities 351. This is conducive to improving the integrity of the entire storage rack 3, avoiding the cylinders protruding outside the storage rack 3, affecting the transfer or placement of other lifting devices or plate rollers, providing more space for other components or devices, so that multiple storage racks 3 can be arranged more compactly, thereby increasing the storage quantity of shafted plate rollers. Optionally, the second cylinder 33 is arranged on one side of the first cylinder 31, and the first cylinder 31 and the second cylinder 33 are arranged in parallel, which can ensure the effective use of the storage space of the mounting cavity 351 and facilitate maintenance when necessary.
[0025] The driving assembly 2 includes a driving motor 21, a gear 23 and a rack 22. Figure 6A driving assembly is shown, a driving motor 21 is fixed on the base 1, a gear 23 is connected to the output shaft of the driving motor 21, a rack 22 is fixed to the moving bar 41, and the gear 23 and the rack 22 are meshed. The output shaft of the driving motor 21 is sleeved with a gear 23, and a horizontally arranged rack 22 meshing with the gear 23 is provided below the gear 23. Compared with the setting of a transmission screw, the setting of the gear 23 and the rack 22 can bear heavy loads without being easily deformed, so that the rack 22 drives the storage rack 3 to move more accurately and smoothly. The driving motor 21 can be a servo motor. When the driving motor 21 is working, it drives the gear 23 to rotate, so that the rack 22 can move relative to the gear 23, and the rack 22 drives the moving bar 41 to move, thereby realizing the movement of the storage rack 3 fixed relative to the moving bar 41 on the base 1. When the motor is working, the output shaft drives the gear 23 to rotate, and the gear 23 is driven to rotate by the forward and reverse rotation of the driving motor 21. The gear 23 rotates and engages with the rack 22, so that the rack 22 will move linearly along the axial direction of the gear 23, realizing the conversion of the rotational motion of the gear 23 into the reciprocating linear motion of the rack 22, thereby changing the moving direction of the mobile frame.
[0026] A slider 36 is provided at the bottom of the storage rack 3, and a second guide rail 45 is fixed on the base 1. The second guide rail 45 is arranged parallel to the first guide rail 42. Figure 4 As shown, the second guide rail 45 is arranged outside the first guide rail 42, and the second guide rail 45 cooperates with the slider 36. When the storage rack 3 moves under the drive of the driving assembly 2, the slider 36 can move along the second guide rail 45, further ensuring the stability of the storage rack 3 when moving forward and backward.
[0027] When it is necessary to place the shaft plate roll on the bracket of one of the storage racks 3 in the middle position, firstly, the first cylinders 31 of the multiple storage racks 3 that need to be moved are matched with the first positioning holes 43 at the corresponding positions on the moving bar 41, that is, the piston rods of the respective first cylinders 31 are inserted into the first positioning holes 43 of the moving bar 41, and the piston rods of the second cylinders 33 are separated from the fixing seat 5. The second cylinders 33 of the remaining moving racks that do not need to be moved are matched with the fixing seat 5, that is, the piston rods of the second cylinders 33 are inserted into the fixing seat 5, and the first cylinders 31 are separated from the moving bar 41. Figure 1As shown, the driving motor 21 is controlled by an external controller, and the driving motor 21 drives the moving bar 41 to move forward, thereby controlling the multiple storage racks 3 that cooperate with the moving bar 41 to move forward synchronously, and the remaining storage racks 3 are in a fixed state and are still fixed in the original position. Multiple storage racks 3 move forward out of the placement space, and then the moving hanging mechanism carries the shaft plate roller to this position, and then the shaft plate roller is placed on the corresponding storage rack 3, and the hanging mechanism moves back to its position after placement. Then the motor reverses and changes the moving direction of the storage rack 3, so that the multiple storage racks 3 that have moved forward are moved backward back to the initial position, so that the storage racks 3 are restored to a compact arrangement. After the return is completed, the piston rod of the first cylinder 31 of each storage rack 3 can be moved upward to disengage from the moving bar 41, and at the same time, the piston rod of the second cylinder 33 moves downward to cooperate with the fixed seat 5, so that all storage racks 3 are restored to a fixed state. Through the above arrangement, when storing, there is no need to move the storage racks 3 one by one, which saves the time required to move a single storage rack 3, and there is no need to independently set a driving motor at the bottom of each storage rack 3, which saves corresponding costs and improves storage efficiency.
[0028] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
