Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a material rack for connecting basket materials into a warehouse. Background Technology

[0002] In the piston manufacturing process, the raw piston castings formed by die casting machines need to undergo key steps such as handling, buffering, and subsequent heat treatment. Since there is usually a considerable distance between the die casting machine and the automated storage and retrieval system used to buffer the raw piston castings, AGV (Automated Guided Vehicle) technology is widely used in the industry as a transfer device to handle the transportation of crates of materials in order to improve the automation level of material transportation, reduce manual intervention costs, and increase production efficiency. Specifically, the crates loaded with raw materials for piston casting are first received by AGV (Automated Guided Vehicle) trolleys from the die-casting machine's output area. The AGVs then transport the crates to the receiving racks of the automated storage and retrieval system (AS / RS) according to a pre-set path. Once the crates are placed on the receiving racks, the stacker cranes in the AS / RS activate, fork up the crates, and move them to a designated location on the rack for buffering, preparing them for subsequent heat treatment processes. However, in actual production, existing material receiving racks can only serve the simple function of carrying crates and do not have the function of adjusting the position of the crates. This leads to a situation where, during the process of AGV trolleys transporting crates to the racks, due to various factors such as the positioning accuracy error of the AGV itself, differences in ground flatness, and the offset of the center of gravity of the crates being loaded, there is often a distance deviation in the front-to-back direction between the actual position of the crates placed on the racks and the preset forklift position of the stacker crane. This positional deviation directly affects the accuracy of the stacker crane's forks in picking up crates: if the deviation is too large, the stacker crane's forks may not be able to accurately insert into the preset position at the bottom of the crate, causing the crate to tilt and the material to shift, affecting the normal operation of subsequent buffering and heat treatment processes. Therefore, given the shortcomings in the position adjustment of existing material racks for connecting crates into the warehouse, there is an urgent need to develop a new type of material rack that can precisely adjust the position of crates to eliminate positional deviations caused by AGV trolley handling, ensure the accuracy and safety of stacker crane forklift operations, and thus improve the overall efficiency of the piston casting raw material storage and transportation process.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a material rack that can readjust and reposition the position of the basket material so as to better connect the material rack for the storage of basket material.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material rack for connecting crates for storage is provided. The rack is U-shaped and includes two side frames and a rear connecting rod connecting the tails of the two side frames. The front of the rear connecting rod forms a loading and unloading entrance for AGV trolleys to enter and exit. The tops of the two side frames jointly support the crates. The top of the side frames is provided with a rear positioning plate. The rear connecting rod is provided with a crate pulling mechanism for aligning the crates with the rear positioning plate. The side frames are provided with a sensing mechanism for detecting the presence of crates.

[0006] As a further improvement to the above technical solution, the rear positioning piece includes an inclined piece, a vertical piece disposed at the bottom of the inclined piece, and a rear flat piece bent and disposed behind the vertical piece. A first inclined surface is formed on the inclined piece to guide the basket material to slide toward the top of the side frame.

[0007] As a further improvement to the above technical solution, the back sides of the inclined plate, the vertical plate, and the rear flat plate are connected by a back support plate.

[0008] As a further improvement to the above technical solution, the basket pulling mechanism includes a first guide rod cylinder disposed on the rear connecting rod and facing forward, a second guide rod cylinder disposed on the output plate of the first guide rod cylinder and facing vertically upward, and a pull head disposed on the output plate of the second guide rod cylinder.

[0009] As a further improvement to the above technical solution, the pull head includes an L-shaped plate and at least two pull ears disposed on the top of the vertical plate of the L-shaped plate, and the flat plate of the L-shaped plate is fixed to the output plate of the second guide rod cylinder.

[0010] As a further improvement to the above technical solution, a back support plate is provided at the inner corner of the L-shaped plate.

[0011] As a further improvement to the above technical solution, the side frame includes a side horizontal tube, a front support frame and a rear support frame set on the side horizontal tube, a front vertical support tube set at the bottom of the side horizontal tube, a rear vertical support tube for connecting the rear connecting rod and the side horizontal tube, and a diagonal support tube connecting the front end of the side horizontal tube and the front vertical support tube. The top surfaces of the front support frame and the rear support frame bear the basket material.

[0012] As a further improvement to the above technical solution, angle irons are provided on the inner sides of the front support frame and the rear support frame, and the angle irons together with the top surfaces of the front support frame and the rear support frame support the basket material.

[0013] As a further improvement to the above technical solution, a correction plate is provided on the outer side of both the front support frame and the rear support frame, and a second inclined surface is formed on the correction plate to guide the basket material to slide to the front support frame and the rear support frame.

[0014] As a further improvement to the above technical solution, the sensing mechanism includes a through-beam photoelectric sensor, with the transmitting end of the through-beam photoelectric sensor disposed on one of the side frames and the receiving end of the through-beam photoelectric sensor disposed on the other side frame.

[0015] Beneficial effects: The material rack provided by this utility model uses a basket-pulling mechanism to align the basket materials and then position them, effectively eliminating positional deviations caused by these deviations and ensuring that the basket materials are in the preset forklift positions of the stacker crane. This precise basket positioning provides reliable assurance for the stacker crane's forklift operation, preventing the stacker crane's forks from failing to accurately insert into the preset bottom position of the basket material due to positional deviations. This prevents basket tilting and material displacement, ensuring the normal operation of subsequent buffering and heat treatment processes. It reduces operational delays and troubleshooting time caused by positional deviations, improves the automation level and continuity of piston casting raw material storage and transportation, and thus enhances overall production efficiency.

[0021] This utility model provides a material rack for connecting baskets of materials into a warehouse. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0023] Please see Figures 1 to 4 This utility model provides a material rack for connecting crates for storage. The material rack is U-shaped and includes two side frame bodies 1 and a rear connecting rod 2 connecting the tails of the two side frame bodies 1. The front of the rear connecting rod 2 forms a loading and unloading entrance for AGV trolleys 8 to enter and exit. The tops of the two side frame bodies 1 jointly support crates 9. The top of the side frame body 1 is provided with a rear positioning piece 3. The rear connecting rod 2 is provided with a crate pulling mechanism 4 for aligning the crates 9 with the rear positioning piece 3. The side frame body 1 is provided with a sensing mechanism 5 for detecting whether crates 9 are present.

[0024] When the AGV trolley, loaded with a basket of raw materials for piston casting, enters through the loading / unloading inlet and places the basket 9 on top of the two side frames 1, the sensing mechanism 5 on the side frames 1 will detect the presence of the basket 9. Subsequently, the basket pulling mechanism 4 on the rear connecting rod 2 will be activated, pulling the basket 9 backward so that the basket 9 is aligned with the rear positioning piece 3 on the top of the side frame 1, thus adjusting the position of the basket 9 so that the stacker crane in the automated storage and retrieval system can accurately pick up the basket 9.

[0025] The material rack provided by this utility model, through the basket pulling mechanism 4, aligns the basket material 9 and positions it with the positioning piece 3, effectively eliminating positional deviations of the basket material 9 and ensuring that the basket material 9 is in the preset forklift position of the stacker crane. Precise positioning of the basket material 9 provides reliable assurance for the stacker crane's forklift operation, avoiding situations where the stacker crane's forks cannot accurately insert into the preset bottom position of the basket material 9 due to positional deviations. This prevents situations such as basket material 9 tilting or material displacement, ensuring the normal operation of subsequent buffering and heat treatment processes. It reduces operational delays and troubleshooting time caused by positional deviations, improves the automation level and continuity of piston casting raw material storage and transportation, thereby enhancing overall production efficiency.

[0026] Specifically, the rear positioning piece 3 includes an inclined piece 31, a vertical piece 32 disposed at the bottom of the inclined piece 31, and a rear flat piece 33 bent behind the vertical piece 32. The inclined piece 31 forms a first inclined surface to guide the basket material 9 to slide towards the top of the side frame 1. The front end face of the vertical piece 32 is a aligning surface, allowing the basket pulling mechanism 4 to properly align the basket material 9 to the vertical piece 32. When the AGV trolley places the basket material 9 too far back, the basket material 9 can slide down along the first inclined surface of the inclined piece 31 to the top of the side frame 1, achieving self-correction. This process, aided by the guiding effect of the inclined surface, prevents the basket material 9 from falling out of the effective bearing range of the side frame 1 due to being placed too far back, ensuring that the basket material 9 is always stably supported by the side frame 1 and preventing the basket material 9 from being suspended or falling.

[0027] Furthermore, the back sides of the inclined plate 31, the vertical plate 32, and the rear flat plate 33 are connected by the back support plate 34, forming a more rigid overall structure. This effectively resists the impact and lateral forces generated when the basket material 9 contacts the rear positioning plate 3 (such as when the basket material 9 slides down the inclined plate 31 or when the basket pulling mechanism 4 drives the basket material 9 to fit against the vertical plate 32), preventing individual plates from deforming, loosening, or breaking due to excessive force, and ensuring that the rear positioning plate 3 can stably perform its positioning and guiding functions for a long time.

[0028] In this embodiment, the basket pulling mechanism 4 includes a first guide rod cylinder 41 disposed on the rear connecting rod 2 and facing forward, a second guide rod cylinder 42 disposed on the output plate of the first guide rod cylinder 41 and facing vertically upward, and a pull head 43 disposed on the output plate of the second guide rod cylinder 42. When the sensing mechanism 5 detects that the basket material 9 is placed on the top of the side frame 1, the basket pulling mechanism 4 is activated: First, the first guide rod cylinder 41 is activated, pushing the second guide rod cylinder 42 and the pull head 43 forward. Then, the second guide rod cylinder 42 is activated, causing the pull head 43 to extend vertically upward, raising the pull head 43 to the corresponding position at the bottom of the basket material 9. Subsequently, the first guide rod cylinder 41 is activated in the opposite direction, pulling the second guide rod cylinder 42 and the pull head 43 backward. The pull head 43 then moves the basket material 9 backward until the basket material 9 is aligned with the vertical piece 32 of the rear positioning piece 3, completely eliminating the positional deviation in the front and rear directions. After positioning is completed, the second guide rod cylinder 42 drives the pull head 43 to return to its vertical position downward, and the first guide rod cylinder 41 also returns to its forward position, waiting for the next basket pulling action.

[0029] The guide rod cylinder has the characteristics of high guiding accuracy and stable output force. The coordinated action of the first guide rod cylinder 41 and the second guide rod cylinder 42 can avoid problems such as jamming and deviation during the pulling process, and ensure that the pulling head 43 exerts a uniform force on the basket material 9 and the direction is stable, preventing the basket material 9 from tilting or the material from scattering during the pulling process.

[0030] Specifically, the pull head 43 includes an L-shaped plate 431 and at least two pull ears 432 set on the top of the vertical plate of the L-shaped plate 431. The flat plate of the L-shaped plate 431 is fixed to the output plate of the second guide cylinder 42, ensuring the overall installation is firm. Several pull ears 432 can contact the basket material 9 from multiple points (the bottom edge of the basket material 9 forms a raised edge 91). Through multi-point force balance, the basket material 9 is prevented from tilting or shifting due to single-point force during the pulling process, ensuring that the basket material 9 always remains stable when pulled, and further improving the accuracy of position adjustment.

[0031] The inner corners of the L-shaped plate are areas where stress is concentrated. When the pull head 43 pulls the basket material 9, the tension on the vertical plate is transmitted to the connection point with the flat plate. Long-term stress can easily lead to deformation or cracking at the inner corners. To address this, a back support plate 433 is provided at the inner corner of the L-shaped plate 431. The back support plate 433 is connected to both the vertical plate and the flat plate of the L-shaped plate to form a triangular support structure, which significantly improves the bending resistance of the inner corners of the L-shaped plate. This ensures that the L-shaped plate maintains structural stability during long-term, high-frequency basket pulling operations and avoids affecting the positional accuracy of the pull head 43 due to deformation.

[0032] Specifically, the side frame 1 includes a side horizontal tube 11, a front support frame 12 and a rear support frame 13 mounted on the side horizontal tube 11, a front vertical support tube 14 located at the bottom of the side horizontal tube 11, a rear vertical support tube 15 connecting the rear connecting rod 2 and the side horizontal tube 11, and a diagonal support tube 16 connecting the front end of the side horizontal tube 11 and the front vertical support tube 14. The top surfaces of the front support frame 12 and the rear support frame 13 support the basket material 9. The side frame 1 supports the basket material 9 together through the top surfaces of the front support frame 12 and the rear support frame 13. This two-point support structure provides a stable foundation for the basket material 9, preventing it from tilting or swaying due to single-point support. Compared to a single flat plate, the frame structure of the front support frame 12 and the rear support frame 13 ensures sufficient load-bearing area while reducing its own weight. It also enhances the adaptability to the bottom of the basket material 9, accommodating the placement needs of basket materials 9 with different bottom structures.

[0033] The bottom of both the front vertical branch pipe 14 and the rear vertical branch pipe 15 is equipped with a ground lock plate 17, which is locked to the ground by expansion bolts and nuts.

[0034] When the basket material 9 is placed on the front support frame 12 and the rear support frame 13, the weight is transferred through the frames to the side horizontal pipe 11, and then from the side horizontal pipe 11 to the front vertical support pipe 14 and the rear vertical support pipe 15, and finally distributed to the ground or the foundation structure of the material rack. The setting of the diagonal bracing pipe 16 further strengthens the connection between the front end of the side horizontal pipe 11 and the front vertical support pipe 14, forming a triangular stable structure, which can effectively resist the bending moment generated by the force on the front end of the side horizontal pipe 11, making the force transmission more uniform and smooth, and reducing stress concentration inside the structure.

[0035] As a preferred technical solution, angle irons 6 are provided on the inner sides of the front support frame 12 and the rear support frame 13. The angle irons 6, together with the top surfaces of the front support frame 12 and the rear support frame 13, jointly support the basket material 9, which is equivalent to adding an additional support structure to the original frame, thereby improving the reliability of the support. The angle irons 6 themselves have high strength and rigidity, which can effectively distribute the weight of the basket material 9, preventing the front support frame 12 and the rear support frame 13 from undergoing local deformation due to long-term heavy loads, further improving the load-bearing stability of the basket material 9, and ensuring reliable support even when the basket material 9 is heavily loaded.

[0036] Furthermore, both the front support frame 12 and the rear support frame 13 are equipped with a correction plate 7 on their outer sides. The correction plate 7 has a second inclined surface 71 formed on it to guide the basket material 9 to slide towards the front support frame 12 and the rear support frame 13. When the AGV trolley places the basket material 9, if there is a lateral positional deviation (such as deviating towards the outer side of the side frame 1), the edge of the basket material 9 will first contact the second inclined surface 71. Under the slight pushing force of gravity or the AGV trolley's placement action, the basket material 9 will slide inward along the second inclined surface 71 and eventually fall into the bearing area of ​​the front support frame 12 and the rear support frame 13, thus automatically correcting the lateral positional deviation and ensuring that the basket material 9 is within the effective bearing range of the side frame 1.

[0037] Preferably, the sensing mechanism 5 includes a through-beam photoelectric sensor. The transmitting end of the through-beam photoelectric sensor is disposed on one of the side frames 1, and the receiving end of the through-beam photoelectric sensor is disposed on the other side frame 1, forming a detection optical path spanning the load-bearing area of ​​the basket material 9. When the basket material 9 is placed on top of the side frame 1, it will block the optical path, and the receiving end will trigger a detection signal because it cannot receive the light signal; if the basket material 9 is not placed or its position is not fully within the load-bearing area, the optical path remains unobstructed, and the sensor does not trigger a signal. The correction plate 7 has a clearance hole for the optical path of the through-beam photoelectric sensor to pass through.

[0038] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
