Description

Technical Field

[0001] The present invention relates to the technical field of stackers, and in particular to an automated precise positioning stacker for intelligent logistics. Background Art

[0002] Logistics stacker cranes are the core equipment of automated warehousing systems. Through the integration of mechanical, electronic, control and computer technologies, they enable precise storage and retrieval of goods between high-rise shelves. Their core functions can be summarized as improving warehousing efficiency, optimizing space utilization, reducing operating costs, ensuring operational safety and supporting flexible production. They are currently widely used in multiple industries, significantly improving warehousing efficiency and space utilization.

[0003] The stacker works by driving the lifting, horizontal movement and extension and retraction of forks through motors to automatically store and retrieve goods, replacing manual handling. When the stacker is working, the middle fork body of the telescopic fork needs to bear the entire load of the front fork arm and the goods when it is extended. Its cantilever structure causes the peak bending moment to appear at the connection between the middle fork body and the fixed fork body. The leverage effect causes the bending moment of the middle fork body to be the largest. At the same time, since the middle fork body needs to bear dual effects when loaded, stress concentration is prone to occur, resulting in increased deflection. In severe cases, the fork cannot be retracted after being extended, and may even get stuck. Long-term use may change the position of the fork end, making it lower than the theoretical position, and the pallet cannot be accurately inserted into the cargo grid, affecting the recognition of the photoelectric sensor, resulting in deviations in the fork stop position, affecting the positioning accuracy.

[0004] Therefore, the present invention provides an intelligent logistics automated precision positioning stacker that can lift and support the suspended part from the bottom when the telescopic fork is extended. Summary of the Invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example: Figures 1-10As shown, the present invention describes an automated precision positioning stacker for intelligent logistics, including a lifting mechanism 1 and a connecting seat 2 installed on the lifting mechanism 1, the connecting seat 2 is fixedly installed with a telescopic fork 3, and the telescopic fork 3 is provided with a transmission assembly 5, a support assembly 6 and a reset assembly 7. The transmission assembly 5 includes a movable rod group and a gear group; the support assembly 6 includes a support rod 62 rotatable with its own center as a fulcrum and a counterweight block 63 slidably connected to the support rod 62, which moves with the middle fork of the telescopic fork 3. When the telescopic fork 3 is extended and loaded, one end of the movable rod group moves downward, and the gear group cooperates to make the movable rod group as a whole into an inverted V shape, and then the counterweight block 63 moves from the fulcrum of the support assembly 6 in the opposite direction of the extension direction of the telescopic fork 3, pulling the support rod 62 to rotate, providing support force for it from the bottom of the middle fork of the telescopic fork 3, reducing the risk of stress concentration, and at the same time, when the telescopic fork 3 is retracted and reset, the reset assembly 7 drives the counterweight block 63 to reset.

[0034] In this embodiment, the telescopic fork 3 is a double-fork arrangement, and a driving motor is provided at one end of the reset assembly 7. The telescopic fork 3 and the reset assembly 7 operate synchronously. When the telescopic fork 3 is extended or retracted, the reciprocating screw 72 rotates synchronously. At the same time, under the action of the connecting assembly 4, the transmission assembly 5 and the support assembly 6 move synchronously with the middle fork. The fulcrum of the support rod 62 is always located at the midpoint of the middle fork. When the front fork carries goods, the suspended end of the middle fork moves slightly downward, thereby squeezing one of the first movable rods 511, causing the first movable rod 511 to rotate, and then under the action of the connecting rack 53, the gear set is operated, thereby driving the other first movable rod 511 to rotate, so that the two first movable rods 511 and 513 are connected. The rod 511 is in an inverted V shape, and under the action of the synchronization component, the two second movable rods 521 are also in an inverted V shape. There is a shift rod 74 on one side of the counterweight block 63 to block it, so that the counterweight block 63 moves in the opposite direction of the extension of the telescopic fork 3, thereby pulling one end of the support rod 62 downward and raising the other end thereof, providing bottom support for the fixed plate 65 between the two middle forks. The lever structure is used to reduce stress concentration. When the telescopic fork 3 is reset, the two movable blocks 73 approach each other, and the shift rod 74 pushes the counterweight block 63 back to its initial position after contacting the counterweight block 63. Under the movement of the counterweight block 63, the first movable assembly 51 and the second movable assembly 52 are restored to a horizontal state.

[0035] Specifically, if Figure 2-Figure 10As shown, the movable rod group includes a first movable component 51 and a second movable component 52. The first movable component 51 includes a group of symmetrically arranged first movable rods 511 and a fixed block 512 fixedly connected to the end of the first movable rod 511. The second movable component 52 is located at the bottom of the first movable component 51 and includes a group of symmetrically arranged second movable rods 521. The gear group includes a group of first gears 54, a group of second gears 55 and a connecting rack 53 respectively meshed with the first gear 54 and the second gear 55. The first gear 54 is meshed with the second gear 55. The first gear 54 and the second gear 55 are both connected to the connecting member 4 1 rotation connection; the transmission assembly 5 also includes a second slide groove 56 opened on the second movable rod 521, and the connecting rack 53 is located on both sides of the end where the first movable rod 511 and the second movable rod 521 are close to each other, and is fixedly connected to the first movable rod 511 and the second movable rod 521 respectively. The connecting rack 53 is arc-shaped and meshes with the gear set. One side of the first gear 54 and the second gear 55 are respectively rotatably connected to a hollow shaft 57. The end of the hollow shaft 57 away from the first gear 54 and the second gear 55 is fixedly connected to the side wall of the connecting member 41. The two ends of the first movable rod 511 and the second movable rod 521 close to each other are fixedly connected. The sides are respectively fixedly connected with a rotating shaft 58, which rotates through the hollow shaft 57 and the side wall of the connecting member 41; a synchronization component is provided between the rotating shaft 58 corresponding to the first gear 54 and the rotating shaft 58 corresponding to the second gear 55; the support assembly 6 also includes a fixed shaft 61 fixedly connected to the connecting member 41 and a group of fixed plates 65 fixedly connected to the middle forks of the two telescopic forks 3, the fixed shaft 61 passes through the support rod 62 and is rotatably connected to the support rod 62, and support blocks 621 are fixedly installed at both ends of the support rod 62, and a third slide groove 622 is provided at the bottom of the support rod 62, and the sliding assembly 6 is slidably connected in the third slide groove 622 4. The sliding assembly 64 includes a second sliding rod 643 that is slidably connected to the third sliding groove 622 and the second sliding groove 56. A slider 644 is fixedly connected to the top of the second sliding rod 643, and a clamping block 641 is fixedly connected to the bottom of the second sliding rod 643. Rollers 642 are respectively provided on both sides of the clamping block 641; the slider 644 is spherical and has a diameter larger than that of the second sliding rod 643. The rollers 642 are rollingly connected to the bottom of the second sliding groove 56. The end of the clamping block 641 away from the second sliding rod 643 is fixedly connected to the counterweight block 63. The fixing block 512 and the support block 621 are both matched with the fixing plate 65; the support rod 62 is set in an inverted V shape.

[0036] In this embodiment, in the initial state, the counterweight 63 is clamped by the two shift rods 74. When the telescopic fork 3 is extended, the two shift rods 74 move in opposite directions at the same time, and one of the shift rods 74 is always in contact with one side of the counterweight 63. When the telescopic fork 3 carries cargo, the middle fork body bears the entire load of the front fork and the cargo, so that the end of the middle fork connected to the front fork moves slightly downward, and then squeezes one end of the first movable rod 511 on one side under the action of gravity, so that the first movable rod 511 rotates with the axis of the corresponding rotating shaft 58 as the center of the circle. When the first gear 54 is rotated, the corresponding connecting rack 53 drives the first gear 54 to rotate, and then the second gear 55 rotates to drive the first movable rod 511 on the other side to rotate, so that the two first movable rods 511 are in an inverted V shape. The synchronization component is set on the rotating shaft 58. One embodiment is to achieve it through the cooperation of the synchronous belt and the synchronous wheel. The rotating shaft 58 passes through the first gear 54, the second gear 55, the hollow shaft 57 and the side wall of the connecting member 41. The rotating shaft 58 corresponding to the first movable component 51 is matched with the rotating shaft 58 corresponding to the second movable component 52 on the same side. The first movable rod 511 and the second movable rod 521 are simultaneously bent into an inverted V shape. After the telescopic fork 3 stops extending, the movable block 73 stops moving at the same time. After loading, the first movable rod 511 and the second movable rod 521 are in an inverted V shape. The gap between the two second movable rods 521 is small. After bending, the roller 642 can roll downward, while the lever 74 on one side of the counterweight 63 blocks it. After the second movable rod 521 is bent, the roller 642 can only move to the other side, that is, the opposite direction of the extension direction of the telescopic fork 3. The counterweight 63 moves When the second slide bar 643 slides in the second slide groove 56 and the third slide groove 622, the slider 644 pulls the support rod 62 to rotate, so that the other end of the support rod 62 is tilted, and the support block 621 at its end is against the bottom of the fixed plate 65 on the same side to support the middle fork of the telescopic fork 3. The support rod 62 is an inverted V-shaped setting as a whole, which can decompose the downward force of the counterweight block 63 into horizontal and vertical components. This force synergy can effectively enhance the supporting force of the support rod 62. Only rubber pads are provided on the top of the fixed block 512 and the support block 621 to avoid rigid friction.

[0037] In this embodiment, if Figure 3As shown, a connecting assembly 4 is provided between the transmission assembly 5 and the telescopic fork 3, and the connecting assembly 4 includes a connecting piece 41 fixedly connected to the middle forks of the two telescopic forks 3 and a first slide groove 42 respectively provided on the opposite side of the fixed forks of the two telescopic forks 3, and the two ends of the connecting piece 41 are respectively fixedly connected to the first slide rod 43, and the end of the first slide rod 43 away from the connecting piece 41 is slidably connected to the first slide groove 42; the movement of the middle fork of the telescopic fork 3 drives the connecting piece 41 to move synchronously, and the movement of the middle fork causes the two first slide rods 43 to slide in the first slide groove 42 on the fixed fork, and the connecting piece 41 and the two first slide rods 43 provide support for the transmission assembly 5 and the support assembly 6. The bending state of the movable rod group is limited by the fixed plate 65. When the support block 621 is against the bottom of the fixed plate 65, the first movable rod 511 and the second movable rod 521 cannot continue to bend.

[0038] Specifically, if Figure 6 As shown, the reset assembly 7 is located on one side of the support assembly 6, and includes a connecting frame 71 fixedly connected to one side of the fixed fork of the telescopic fork 3. The connecting frame 71 is rotatably connected to a reciprocating screw 72, and the reciprocating screw 72 rotates through a set of movable blocks 73. The movable blocks 73 are slidably engaged with the connecting frame 71, and a shift rod 74 is fixedly connected to the bottom of the movable blocks 73; the two movable blocks 73 make synchronous reverse movements.

[0039] When the fork 3 is in the initial state, the center of the middle fork and the center of the reciprocating screw 72 are on the same vertical line. At this time, the distance between the two movable blocks 73 is the shortest, and the two shift rods 74 are both in contact with the side of the counterweight 63. The slot of the reciprocating screw 72 is composed of two sections, and the two sections are symmetrically arranged. When the telescopic fork 3 is extended, the reciprocating screw 72 rotates, so that the two movable blocks 73 move away from each other at the same time. The movable block 73 is slidably engaged with the connecting frame 71 so that the movable block 73 can only move horizontally. During the process, the shift rod 74 on the same side of the fork extension direction is always in contact with the counterweight 63 until the fork load causes the first movable rod 511 and the second movable rod 521 to rotate, and the counterweight 63 is produced. When the fork is reset, the reciprocating screw 72 rotates again, causing the two movable blocks 73 to approach each other at the same time. The lever 74 on the same side of the counterweight 63 contacts the counterweight 63 and pushes the counterweight 63, causing the roller 642 to roll in the second slide groove 56 until the counterweight 63 returns to the fulcrum of the support rod 62. At the same time, under the action of the gravity of the counterweight 63, the counterweight 63 presses the ends of the two second movable rods 521 that are close to each other, causing the second movable rod 521 to rotate in the opposite direction, and the lower end moves upward until the fixed block 512 abuts against the bottom of the fixed plate 65, thereby restoring the first movable rod 511 and the second movable rod 521 to a horizontal state.

[0040] Working principle: When the stacker is in use, the lifting mechanism 1 drives the connecting seat 2 to move vertically, and the telescopic fork 3 is extended. When the middle fork moves, it drives the transmission assembly 5 and the support assembly 6 to move synchronously under the action of the connecting assembly 4. The movable rod group is in a horizontal state at this time. The fixed block 512 on the first movable rod 511 is against the bottom of the fixed plate 65, and the counterweight block 63 is located at the fulcrum of the support rod 62. One of the shifting rods 74 is attached to one side of the counterweight block 63. When the front fork carries goods, the connection between the middle fork and the front fork moves downward slightly, so that the first movable rod 511 on the same side of the goods is slightly rotated with the axis of the corresponding rotating shaft 58 as the center of the circle, and the corresponding gears 53, the first gear 54 and the second gear 55 are connected. Under mutual cooperation, the first movable rod 511 on the other side rotates at the same time, so that the two first movable rods 511 are changed from a straight state to an inverted V shape, and the synchronization component makes the second movable component 52 also change to an inverted V shape, thereby making the counterweight block 63 move in the opposite direction of the extension of the telescopic fork 3, thereby pulling the support rod 62 to rotate, so that one end of the support rod 62 is tilted, and the support block 621 is abutted against the bottom of the fixed plate 65, supporting the middle fork of the telescopic fork 3 upward, reducing the risk of stress concentration at the connection between the front fork and the middle fork, and suppressing the deformation of the fork body from affecting the positioning accuracy. When the telescopic fork 3 is reset, the reset component 7 that operates synchronously with it uses the shift rod 74 to push the counterweight block 63 back to the initial position for subsequent work.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
