Description

Technical Field

[0001] This invention relates to the field of logistics equipment, specifically to a high-speed bin stacker crane. Background Technology

[0002] As a core piece of equipment in automated storage and retrieval systems (AS / RS), the technological background of stacker cranes can be traced back to the explosive growth in demand for warehouse automation in the mid-20th century. Traditional warehousing models rely on manual operation, which suffers from pain points such as low efficiency, poor space utilization, and high labor costs. The emergence of stacker cranes marks a leap forward in the warehousing industry towards "three-dimensional" and "fully automated" systems.

[0003] Patent application CN202220510426.1 discloses a high-speed bin stacker crane, including a ground rail, a column component, a loading platform component, a traveling power component, a lower crossbeam component, a traveling mechanism, and a lifting mechanism. The loading platform component moves up and down on the column component. The lifting mechanism includes a lifting timing belt to provide power for the movement of the loading platform component. The traveling power component provides horizontal power for the stacker crane. The lower crossbeam component is the chassis of the stacker crane. The traveling mechanism is mounted on the chassis, and the two ends of the traveling timing belt are fixed to the ground rail to provide traction for the traveling mechanism. The traveling timing belt is installed in the traveling direction along the center of gravity projection of the stacker crane and is centrally located. The crane experiences uniform horizontal force and has no deflection torque, which is more conducive to ensuring the stability of the equipment during high-speed operation.

[0004] However, this patent only allows one container to be placed at a time for single-stage palletizing, which greatly increases the palletizing time.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0036] like Figures 1 to 8 As shown, the high-speed bin stacker of the present invention includes: a sliding seat 1, a vertical rod 2 fixedly installed on the sliding seat 1, a placement frame 3 slidably installed on the vertical rod 2, a driving mechanism 4 for driving the placement frame 3 to move along the vertical rod 2, and a feeding mechanism 5 disposed on the placement frame 3;

[0037] The feeding mechanism 5 includes: a support rod 51 fixedly installed on the placement frame 3, a sprocket 52 rotatably installed on the support rod 51, a chain 53 meshing with the sprocket 52, grid bars 54 fixedly installed at equal intervals on the chain 53, and a drive motor 55 coaxially fixedly connected to the sprocket 52.

[0038] In the automated palletizing process for material bins, the operator only needs to precisely position the bin to be palletized on the lowest-level grid bar 54 component near the placement rack 3. Then, the drive motor 55 starts running, driving the sprocket 52 to rotate, which in turn drives the chain 53 system meshing with it, and the grid bar 54 fixedly connected to specific nodes of the chain 53 to move upwards synchronously. During this process, the operator can simultaneously place subsequent bins to be palletized onto the surface of the next-level grid bar 54 component. Through this hierarchical progressive operation mode, multiple sets of bins can be continuously and orderly stacked. This technical solution significantly optimizes material storage and retrieval efficiency in the bin lifting and palletizing process, effectively shortening the cycle time of material retrieval operations.

[0039] The feeding mechanism 5 adopts a four-group symmetrical layout design (specific structure as follows). Figure 3 As shown in the figure, this configuration ensures that the hopper is placed stably and evenly on the surface of the grid bar 54 component.

[0040] The drive mechanism 4 includes: a second motor 41 fixedly mounted on the vertical rod 2, a winding roller 42 fixedly mounted on the output shaft of the second motor 41, a pull rope 43 fixedly mounted on the winding roller 42, and a placement frame 3 fixedly connected to one end of the pull rope 43;

[0041] When it is necessary to lift the materials on the placement rack 3, motor 41 starts and drives the winding roller 42 to rotate. As the winding roller 42 continues to rotate, its matching pull rope 43 is wound in an orderly manner around the surface of the winding roller 42, thereby driving the placement rack 3 to move vertically upwards along the preset vertical rod 2 through mechanical traction. After the placement rack 3 is lifted to the designated position at the same height as the shelf, the precise stacking operation of the material box can be completed.

[0042] To achieve refined and dynamic management of goods, standardized labels are typically affixed to the surfaces of the bins before palletizing. An integrated label scanning system then automatically identifies the bins' preset stacking positions, thereby optimizing warehouse space utilization and stacking logic. During operation, the surface of the bin with the electronic label must be precisely aligned with the scanning device's sensing area to ensure the completeness and accuracy of data collection.

[0043] The placement rack 3 is also equipped with a correction mechanism 6;

[0044] The correction mechanism 6 includes: a turntable 61 rotatably mounted on the placement frame 3, a drive motor 62 that drives the turntable 61 to rotate, a wave groove 63 formed on the turntable 61, a hinge rod 64 slidably mounted in the wave groove 63, a push plate 65 hinged to the hinge rod 64, and the push plate 65 slidably mounted on the placement frame 3.

[0045] During the bin palletizing operation, the operator can place the bins to be palletized onto the surface of the grid bar 54 assembly in a non-strict order. After starting motor 55, the grid bar 54 assembly is driven vertically through the chain drive system, causing the bins on the grid bar 54 to fall sequentially onto the surface of the rotating turntable 61 of the placement rack 3 under gravity. Subsequently, motor 62 drives the turntable 61 to rotate in a directional manner until the label pasting surface of the bin on the turntable 61 is precisely aligned with the scanning device preset on the side of the placement rack 3 (this scanning mechanism adopts the existing technical standard configuration, and its specific structure will not be described in detail here). After the scanning device acquires the bin information through optical recognition technology, the system automatically generates the optimal stacking path planning instruction.

[0046] The push plate 65 is symmetrically provided in two sets, and is respectively connected to the two symmetrical sides of the wave groove through the hinge rod 64.

[0047] During the rotation of the turntable 61, the pre-set wave groove 63 structure on its surface drives two symmetrically arranged push plate 65 assemblies to move linearly closer together via a mechanical linkage mechanism. This allows the ends of the push plates 65 to flexibly contact the outer contour of the hopper, thereby achieving spatial posture correction of the hopper. Specifically, when the turntable 61 completes a 90° directional rotation, the two sets of push plates 65 move synchronously towards the center and apply a balanced squeezing force, ensuring that each surface of the hopper maintains a strict parallel relationship with the preset coordinate system. After the posture correction is completed, when the turntable 61 enters the next rotation cycle, the contour curve of the wave groove 63 drives the push plate 65 assemblies to move in the opposite direction, maintaining a safe distance between the push plates 65 and the outer surface of the hopper. This design, through a dynamic gap control mechanism, effectively avoids mechanical interference between the push plates 65 and the edge structure of the hopper during rotation, ensuring the decoupling of the posture correction mechanism 6 and the turntable 61 drive system.

[0048] The push plate 65 is also equipped with a cleaning component 7;

[0049] The cleaning component 7 includes: a cleaning roller 71 rotatably mounted on the push plate 65, and a motor 72 that drives the cleaning roller 71 to rotate; the cleaning roller 71 is provided in multiple sets; and a rotating belt 73 is provided between each pair of cleaning rollers 71.

[0050] When the push plate 65 forms a stable contact with the surface of the material box, motor 4 72 starts and drives the built-in cleaning roller 71 to perform rotational motion. The high-density bristles on the surface of the cleaning roller 71 efficiently peel off and collect dust particles attached to the side walls of the material box through continuous contact friction, effectively eliminating the attenuation of label optical recognition caused by dust accumulation on the box surface. When motor 3 62 drives the turntable 61 to perform multi-degree-of-freedom rotation, the relative motion trajectory of the cleaning roller 71 and the material box forms a spatial envelope coverage. Combined with the intermittent positioning rotation strategy of the turntable 61, it can achieve dynamic cleaning of the material box without dead angles. Compared with the traditional single-axis cleaning mode, this design increases the effective cleaning area per unit time by 300%. At the same time, it couples the cleaning operation with the posture correction process in time and space, significantly optimizing the time utilization rate of the overall operation process.

[0051] The push plate 65 is also provided with a scraping component 8 for scraping the cleaning roller 71.

[0052] The scraping assembly 8 includes: a sealing chamber 81 fixedly installed on the push plate 65, a scraper 82 fixedly installed in the sealing chamber 81, an air extraction chamber 83 opened in the sealing chamber 81, a piston 84 slidably installed in the air extraction chamber 83, one end of the piston 84 being fixedly connected to the placement frame 3, an air port 85 opened on the air extraction chamber 83, and the air port 85 being connected to the external suction pump through a hose 86.

[0053] When motor 72 drives cleaning roller 71 to rotate, its scraper 82 is in close contact with the surface of cleaning roller 71 to scrape off the dust on cleaning roller 71. When turntable 61 rotates, push plate 65 moves towards the box body, and suction chamber 83 moves synchronously under the drive of push plate 65. The piston 84 creates negative pressure in suction chamber 83 under the movement of suction chamber 83, which draws out the dust scraped by scraper 82 on cleaning roller 71, reduces dust in the sealed cavity, improves the cleanliness of cleaning roller 71, thereby improving the cleanliness of the material box surface and improving label capture efficiency.

[0054] Furthermore, when the push plate 65 approaches the material box, its piston 84 passes the air hole on the suction chamber 83, and its sealing chamber 81 connects with the suction pump. The suction pump provides sufficient negative pressure to the sealing chamber 81 to ensure that the dust generated when the cleaning roller 71 is in close contact with the material box for cleaning can be quickly removed. When the push plate 65 moves away from the material box, its piston 84 can block the connection with the air pump, reducing energy consumption.

[0055] In summary, when motor 62 drives turntable 61 to rotate, on the one hand, it adjusts the posture of the material box to ensure that the side of the material box with the label is close to the scanning mechanism, thereby improving the scanning accuracy; on the other hand, it drives push plate 65 to approach the material box and clean the side wall of the material box to prevent dust on the side wall of the material box from affecting the label recognition effect; moreover, when push plate 65 moves, it can also absorb the dust generated by cleaning roller 71.

[0056] The placement rack 3 is also equipped with a pushing component 9;

[0057] The pushing component 9 consists of a cylinder 91 and a baffle 92; the cylinder 91 is fixedly installed on the placement frame 3, and the baffle 92 is fixedly connected to the piston rod 84 of the cylinder 91.

[0058] After the bin is scanned by the scanning mechanism, cylinder 91 pushes the bin into the shelf to complete the stacking.
