Description

Technical Field

[0001] The present invention relates to the technical field of stackers, in particular to an automated high-speed stacker with an emergency stop buffer function. Background Art

[0002] A stacker crane is a type of cargo storage and retrieval equipment used in automated high-bay warehouses. It achieves efficient and accurate cargo handling through a mechanical structure. It is the core equipment of high-bay warehouses and is mainly used to run back and forth between warehouse aisles to achieve cargo storage and retrieval operations.

[0003] A Chinese invention with application publication number CN118515097B discloses a high-speed material box stacker, including a bottom box, a vertical frame fixedly connected to the top of the bottom of the bottom box, a sliding seat slidably sleeved on the outer side of the vertical frame, a support plate fixedly installed on one side of the sliding seat, and guide rails fixedly connected to the front and rear sides of the bottom of the bottom box; a drive mechanism is used to drive the sliding seat to rise and fall, and a counterweight mechanism is used to adjust the center of gravity position of the bottom box.

[0004] However, the inventors found that during actual use, when the stacker stops suddenly, only adjusting the position of its counterweight block by the base has little effect on the goods moved to the upper end. Based on this, we proposed an automated high-speed stacker with an emergency stop buffer function. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology. A carrier is provided on one side of the vertical rail, a buffer plate is slidingly provided on the carrier, an electromagnetic induction is provided between the buffer plate and the carrier, a load-bearing box is provided on the other side of the vertical rail, a counterweight block is provided in the load-bearing box, and a linkage assembly is provided inside the vertical rail. When the stacker stops suddenly, the goods on the carrier will generate an impact force due to inertia, causing the electromagnetic induction to be disconnected. When the buffer plate slides on the carrier, it is driven by the linkage assembly, and the counterweight block moves in the opposite direction to balance the forward impact of the goods, avoid the stacker from tipping over, and ensure the stability of the goods.

[0006] In view of the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] An automated high-speed stacker with an emergency stop buffer function comprises a base, a vertical rail fixedly connected to the top of the base, a platform slidingly provided on one side of the vertical rail, a buffer plate slidingly provided on the platform, electromagnetic induction provided between the buffer plate and the platform, a load-bearing box provided on the other side of the vertical rail, a counterweight block provided in the load-bearing box, a linkage assembly provided inside the vertical rail, and the linkage assembly being used to drive the buffer plate and the counterweight block to move relative to or away from each other.

[0008] Preferably, the linkage assembly includes a first slide groove arranged inside the vertical rail, a moving block slidingly arranged in the first slide groove, a rotating shaft rotatably arranged in the moving block, a gear fixedly arranged on the rotating shaft, and a first rack and a second rack respectively arranged at the upper and lower ends of the gear and meshing with the gear.

[0009] As a preference, the first rack is fixedly connected to the lower end surface of the buffer plate, and the second rack is fixedly connected to the upper end surface of the counterweight block.

[0010] As a preference, rotating wheels are evenly distributed on the lower end of the counterweight block, a track is provided in the load-bearing box, and the rotating wheels roll and move in the track.

[0011] As a preference, the outer surface of the vertical rail is provided with two parallel slide grooves, and the carrier platform and the load-bearing box are respectively slidably arranged in the slide grooves.

[0012] As a preference, a T-shaped slide groove is provided on the upper surface of the carrier, a T-shaped protrusion is provided on the lower end surface of the buffer plate, and the T-shaped protrusion is slidably arranged in the T-shaped slide groove.

[0013] As a preference, support rods are provided at the upper and lower ends of the moving block, and the support rods are fixedly connected to the carrier and the load-bearing box respectively.

[0014] As another preferred embodiment, a lead screw is provided through the carrier, and a drive motor is provided at the upper end of the vertical rail, and the drive motor is used to drive the lead screw to rotate.

[0015] Beneficial effects of the present invention:

[0016] In the present invention, the cargo buffer plate and the counterweight block are linked together. When the stacker stops suddenly, the cargo on the platform will generate an impact force due to inertia, causing the electromagnetic induction to be disconnected. When the buffer plate slides on the platform, it is driven by the linkage component, and the counterweight block moves in the opposite direction to balance the forward impact of the cargo, avoid the stacker from tipping over, and ensure the stability of the cargo.

[0017] In summary, the equipment has the advantages of stable center of gravity and buffer function, and is particularly suitable for the field of stacker technology. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1 to 8 As shown, an automated high-speed stacker with an emergency stop buffer function includes a base 1, a vertical rail 2 is fixedly connected to the top of the base 1, a platform 3 is slidably provided on one side of the vertical rail 2, a buffer plate 4 is slidably provided on the platform 3, an electromagnetic induction 5 is provided between the buffer plate 4 and the platform 3, a load-bearing box 6 is provided on the other side of the vertical rail 2, a counterweight 7 is provided in the load-bearing box 6, a linkage assembly 8 is provided inside the vertical rail 2, and the linkage assembly 8 is used to drive the buffer plate 4 and the counterweight 7 to move relative to or away from each other.

[0031] like Figures 2 to 5As shown, the linkage assembly 8 includes a first slide 81 disposed inside the vertical rail 2, a moving block 82 slidably disposed in the first slide 81, a rotating shaft 83 rotatably disposed in the moving block 82, a gear 84 fixedly disposed on the rotating shaft 83, and a first rack 85 and a second rack 86 disposed at the upper and lower ends of the gear 84 and meshing with the gear 84. The first rack 85 is fixedly connected to the lower end surface of the buffer plate 4, and the second rack 86 is fixedly connected to the upper end surface of the counterweight 7.

[0032] In this embodiment, the first rack 85 drives the gear 84 to rotate, thereby driving the second rack 86 to move in the opposite direction, and driving the counterweight block 7 under the second rack 86 to move in the opposite direction to the buffer plate 4.

[0033] like Figure 6 As shown, rotating wheels 71 are evenly distributed on the lower end of the counterweight block 7 , a track 61 is provided in the load-bearing box 6 , and the rotating wheels 71 roll and move in the track 61 .

[0034] It is worth mentioning here that the counterweight 7 is heavy, and the counterweight 7 is easily moved by sliding the rotating wheels 71 in the track 61 .

[0035] like Figure 7 As shown, the outer surface of the vertical rail 2 is provided with two parallel slide grooves 21, and the carrier 3 and the load-bearing box 6 are slidably arranged in the slide grooves 21 respectively.

[0036] like Figure 8 As shown, a T-shaped slot 31 is provided on the upper surface of the carrier 3 , and a T-shaped protrusion 41 is provided on the lower end surface of the buffer plate 4 . The T-shaped protrusion 41 is slidably provided in the T-shaped slot 31 .

[0037] like Figure 3 As shown, support rods 87 are provided at the upper and lower ends of the moving block 82 , and the support rods 87 are fixedly connected to the carrier 3 and the load-bearing box 6 respectively.

[0038] It is worth mentioning that, by providing the support rods 87 at both ends, the platform 3 can simultaneously drive the moving block 82 and the load-bearing box 6 to move synchronously when the platform 3 moves.

[0039] like Figure 7 As shown, a lead screw 22 is provided through the carrier 3 , and a drive motor 23 is provided at the upper end of the vertical rail 2 , and the drive motor 23 is used to drive the lead screw 22 to rotate.

[0040] In this embodiment, the lead screw 22 is driven to rotate by the driving motor 23 , so that the platform 3 is limited in the vertical rail 2 , and the platform 3 moves longitudinally in the vertical rail 2 .

[0041] The working process is as follows:

[0042] Start the drive motor 23 to drive the lead screw 22 to rotate, driving the platform 3 to move longitudinally in the vertical rail 2, and through the connection arrangement of the support rod 87, drive the moving block 82 and the load-bearing box 6 to move synchronously;

[0043] When the stacker stops suddenly, the buffer plate 4 of the load will generate an impulse due to the effect of inertia. When the impulse is greater than the suction force of the electromagnetic induction 5, the first rack 85 drives the buffer plate 4 to move forward, the driving gear 84 rotates, and drives the second rack 86 to move in the opposite direction, driving the counterweight block 7 under the second rack 86 to move in the opposite direction of the buffer plate 4.

[0044] When the force of inertia disappears, the first rack 85 will move the buffer plate 4 back, and the adsorption force of the electromagnetic induction 5 will cause the buffer plate 4 to be adsorbed on the carrier 3 again.

[0045] Of course, in this technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0046] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art based on the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
