Description

Technical Field

[0001] This invention relates to the field of intelligent warehousing equipment technology, specifically to an intelligent stacker. Background Technology

[0002] In traditional machining and sheet metal manufacturing, sheet metal materials are often stored in flat stacks or simple shelves, which not only occupies a lot of workshop space, but also requires repeated stacking and relocation when retrieving materials from lower levels, consuming a lot of manpower and time, and posing significant safety hazards. In recent years, automated storage and retrieval systems (AS / RS) technology has developed rapidly. Stacker cranes, as core equipment, are widely used in the storage and retrieval operations of high-rise racks. Existing stacker cranes are usually composed of a frame, a traveling mechanism, a lifting mechanism, and a telescopic mechanism. They can travel horizontally along the aisle track, the loading platform can be lifted and lowered vertically along the columns, and the forks can be extended and retracted to the storage compartments on both sides to realize the storage and retrieval of goods in three-dimensional space. However, existing stacker cranes still have some problems when stacking sheet metal materials: the lifting system of traditional stacker cranes mostly uses wire rope winches or single hydraulic cylinders for driving. When carrying heavy sheet metal materials, they are prone to swaying and uneven loading during the lifting process. In addition, after long-term use, the wire ropes undergo plastic elongation, and the accuracy of the vertical movement continues to decline. Secondly, the rigidity of the traditional stacker crane's track frame structure is insufficient, resulting in shaking and large displacement deviations during the start and stop process. It is impossible to cooperate with a high-precision positioning mechanism to complete fixed-point stopping and precise alignment operations. Therefore, we propose an intelligent stacker crane to solve the above problems. Summary of the Invention

The telescopic mechanism 5 includes a structural support 51, and telescopic components 52 are fixedly installed on both sides of the top of the structural support 51. The telescopic assembly 52 includes a structural frame 521, which is fixedly installed on the top of the structural support 51 by bolts.

By activating the second motor 54, and cooperating with the third transmission sprocket 55, the fourth transmission sprocket 551, and the second chain 552, the drive shaft 53 is controlled to rotate. By controlling the rotation of the drive shaft 53, the second gear 5213 in the two telescopic components 52 is driven to rotate. In conjunction with the meshing connection of the third rack 5221, the first telescopic frame 522 is driven to slide out. At the same time, in conjunction with the meshing connection of the first gear 527 and the second rack 526, the first gear 527 is controlled to rotate synchronously.

By controlling the rotation of the first shaft 43, the first sprocket 431 is driven to rotate, thereby pulling the long chain 47. In conjunction with the transmission of the second sprocket 441, the third sprocket 451, and the fourth sprocket 461, the transmission of the fifth sprocket 81, the sixth sprocket 821, the seventh sprocket 831, and the eighth sprocket 841 is controlled to rise, thereby controlling the telescopic mechanism 5 to rise stably. Compared with traditional lifting systems, this lifting mechanism 4 can reduce swaying and uneven load during the lifting process. Moreover, the plastic elongation of the long chain 47 is small after long-term use, which improves the accuracy of the vertical movement of the telescopic mechanism 5, thereby improving the stacking accuracy of the intelligent stacker crane.

[0043] The lifting mechanism 4 also includes a first drive shaft 48 and a first motor 49. A first rotating seat 481 is rotatably mounted on the outer side of the first drive shaft 48. The first rotating seat 481 is fixedly mounted on the top of the base bracket 3. The two ends of the first drive shaft 48 are respectively fixedly mounted to the ends of the first shaft 43 in the lifting group.

A second transmission sprocket 492 is fixedly mounted on the outer side of the first drive shaft 48. A transmission chain 493 is meshed with the outer sides of the first transmission sprocket 491 and the second transmission sprocket 492. By turning on the first motor 49, the first drive shaft 48 is controlled to rotate in coordination with the transmission of the first transmission sprocket 491, the second transmission sprocket 492 and the transmission chain 493, thereby controlling the first shaft 43 in the lifting groups on both sides to rotate synchronously.

[0044] A protective cover 85 is fixedly installed on the inner side of the structural support 51 in the telescopic mechanism 5. A long chain 47 moves through the protective cover 85. The fifth sprocket 81, the sixth sprocket 821, the seventh sprocket 831 and the eighth sprocket 841 are located in the protective cover 85.

[0045] In the telescopic mechanism 5, a positioning block 9 is movably mounted in the middle of the structural support 51. A movable sleeve block 91 is fixedly installed at both the bottom and top of the positioning block 9. A drive screw 92 is threadedly installed in the middle of the movable sleeve block 91. The drive screw 92 is rotatably mounted on the structural support 51 in the telescopic mechanism 5. A transmission wheel 93 is fixedly mounted at the end of the drive screw 92 away from the movable sleeve block 91. A transmission belt 931 is movably sleeved on the outer side of the two transmission wheels 93. A drive motor 94 is fixedly mounted on the structural support 51 in the telescopic mechanism 5 near one of the drive screws 92. The drive end of the drive motor 94 is fixedly mounted to the shaft end of the corresponding drive screw 92. A positioning slot 9 is provided on the outer side of the side support 2 to cooperate with the positioning block 9. 01. Positioning block 9 is movable in positioning slot 901. After the telescopic mechanism 5 is raised and lowered to a certain height, the drive motor 94 can be turned on immediately. With the transmission of the two transmission wheels 93 and the transmission belt 931, the two drive screws 92 are controlled to rotate synchronously. This controls the positioning block 9 to move to one side of the side support 2, so that the positioning block 9 is movable in positioning slot 901. This provides auxiliary limit for the telescopic mechanism 5, reduces the static load on the long chain 47 when the height position of the telescopic mechanism 5 remains unchanged, and further improves the overall use effect of the intelligent stacker. Conversely, turning on the drive motor 94 controls the two drive screws 92 to rotate synchronously in opposite directions, so that the positioning block 9 slides out of positioning slot 901 in the opposite direction, and the telescopic mechanism 5 loses its limit.

[0046] In the telescopic mechanism 5, two symmetrically distributed first auxiliary shafts 7 and two symmetrically distributed second auxiliary shafts 72 are rotatably mounted on the structural support 51 via bearings. A first limiting wheel 71 is fixedly mounted at the end of the first auxiliary shaft 7, and a second limiting wheel 721 is fixedly mounted at the end of the second auxiliary shaft 72. A limiting guide rail 73 is fixedly mounted on the outer side of the side support 2. The first limiting wheel 71 and the outer side of the limiting guide rail 73 are in contact, and the second limiting wheel 721 rolls and is locked on the outer side of the limiting guide rail 73. When the telescopic mechanism 5 is raised and lowered, the first limiting wheel 71 and the second limiting wheel 721 roll and are limited on the outer side of the limiting guide rail 73, which further improves the stability of the telescopic mechanism 5 when it is raised and lowered, thereby improving the stability of stacked sheet metal materials.

A drive component 62 is fixedly installed at the bottom end of the mounting bracket 61.

The bottom of the drive sleeve 624 is rolled and locked on the top of the bottom drive guide wheel 63 and makes high friction contact with the surface of the bottom drive guide wheel 63. The top side limit wheel 629 contacts the side end of the bottom drive guide wheel 63. By controlling the drive sleeve 624 to rotate, and by the limit of the top side limit wheel 629, the entire stacker crane is driven to move automatically and stably in the horizontal direction in the warehouse.

[0049] A top support guide rail 11 is provided above the top support 1. The top support guide rail 11 is installed on the warehouse floor. Multiple U-shaped support frames 12 are fixedly installed on the top support 1. Bottom support guide wheels 121 are rotatably installed at both ends of the U-shaped support frame 12. Bottom support horizontal grooves 111 corresponding to the bottom support guide wheels 121 are opened at the bottom end of the top support guide rail 11. The bottom support guide wheels 121 are rolled and locked in the bottom support horizontal grooves 111. Two symmetrically distributed L-shaped supports 13 are fixedly installed on the top support 1 near the U-shaped support frame 12.

The side end of the top support guide rail 11 is provided with a bottom side transverse groove 112 corresponding to the bottom side limiting wheel 132. The bottom side limiting wheel 132 rolls and is stuck in the bottom side transverse groove 112. When the entire stacker crane moves horizontally in the warehouse, the bottom support guide wheel 121 is supported and rolls in the bottom support transverse groove 111, and the bottom side limiting wheel 132 is limited and rolls in the bottom side transverse groove 112, which further improves the stability of the entire stacker crane's horizontal movement.

[0050] Working principle: The bottom drive guide wheel 63 is installed inside the warehouse, and the top support guide rail 11 is installed inside the warehouse; When heavy sheet metal needs to be stacked, the worm gear motor 626 is turned on, which drives the drive shaft 627 to control the inner rotating cylinder 623 to rotate, thereby controlling the drive sleeve wheel 624 to rotate. Through the limit of the top side limit wheel 629, the entire stacker crane carries the sheet metal to move automatically and stably in the horizontal direction in the warehouse. The first barcode locator is used to accurately locate the horizontal movement position of the intelligent stacker crane. With the help of two track limiters, the stacker crane carries the sheet metal to the warehouse scanning point and stops the worm gear motor 626. Subsequently, the first motor 49 is turned on, and in conjunction with the transmission of the first transmission sprocket 491, the second transmission sprocket 492 and the transmission chain 493, the first drive shaft 48 is controlled to rotate, thereby controlling the first shaft 43 in the lifting groups on both sides to rotate synchronously, driving the first sprocket 431 to rotate, thereby pulling the long chain 47, and in conjunction with the transmission of the second sprocket 441, the third sprocket 451 and the fourth sprocket 461, controlling the transmission of the fifth sprocket 81, the sixth sprocket 821, the seventh sprocket 831 and the eighth sprocket 841 to rise, thereby controlling the telescopic mechanism 5 to rise stably. The second barcode locator is used to accurately position the lifting position of the telescopic mechanism 5, so that the telescopic mechanism 5 carrying the sheet metal rises to the shelf position of the corresponding scanning point in the warehouse, and the first motor 49 is stopped. Then the drive motor 94 is turned on, and in conjunction with the transmission of the two transmission wheels 93 and the transmission belt 931, the two drive screws 92 are controlled to rotate synchronously, thereby controlling the positioning block 9 to move to one side of the side support frame 2, so that the positioning block 9 is moved into the positioning slot 901, which assists in limiting the telescopic mechanism 5 and reduces the static load of the long chain 47 when the height position of the telescopic mechanism 5 remains unchanged. Subsequently, the telescopic mechanism 5 is precisely inserted into one shelf, and the tray is placed on the crossbeam using the telescopic mechanism 5. Then, the drive motor 94 is turned on, controlling the two drive screws 92 to rotate synchronously in opposite directions, causing the positioning block 9 to slide in the opposite direction and disengage from the positioning slot 901, and the telescopic mechanism 5 loses its limit. Then, the first motor 49 is turned on again to control the first drive shaft 48 to rotate in the opposite direction, thereby controlling the telescopic mechanism 5 to descend slightly, the pallet is lowered, and the stacking of the heavier sheet metal is completed. Subsequently, the telescopic mechanism 5 retracts; When the telescopic mechanism 5 is raised or lowered, the first limiting wheel 71 and the second limiting wheel 721 roll on the outside of the limiting guide rail 73 to further improve the stability of the telescopic mechanism 5 when it is raised or lowered, thereby improving the stability of the stacked sheet metal materials.
