Description

Technical Field

[0001] This utility model relates to the field of parts storage and transfer technology, and in particular to a large-capacity parts storage system. Background Technology

[0002] In large-scale parts machining scenarios and parts warehousing and transfer environments, there is often a need for large-capacity storage. However, existing technologies typically present challenges in storing and transferring large warehouse racks. Furthermore, as the height and length of the racks increase, as does the weight of the parts, stability deteriorates, leading to issues such as swaying and tilting. This results in spatial distance errors between the placement of parts and tooling and their intended locations, causing interference and collisions during parts retrieval and potentially impacting efficiency and even causing racks to tip over. Utility Model Content

[0003] This utility model aims to solve the above problems and provides a large-capacity parts storage system, the technical solution of which is as follows: A high-capacity parts storage system includes storage racks for storing parts and a transfer mechanism for moving parts. The storage racks include multiple vertically arranged longitudinal support frames in two parallel rows. Each row contains multiple longitudinal support frames that are parallel to each other in the vertical plane. The longitudinal support frames in the two rows are arranged in pairs. A storage tray for placing parts or tooling is provided between each pair of longitudinal support frames. The storage tray has a planar structure. A horizontal feeding crossbar is fixedly connected to each row of longitudinal support frames. A feeding channel is formed between the feeding crossbeams; the transfer mechanism is set on one side of the storage rack, and the transfer mechanism includes a horizontal transfer guide rail, a vertical transfer guide rail, a movable frame and a material picking and placing mechanism. The horizontal transfer guide rail is set parallel to the feeding crossbeam, the vertical transfer guide rail is set parallel to the longitudinal support frame, and the vertical transfer guide rail is slidably set on the horizontal transfer guide rail. The movable frame is slidably set on the vertical transfer guide rail, and the material picking and placing mechanism is fixedly connected to the movable frame. The material picking and placing mechanism includes a sliding frame that moves in the horizontal plane perpendicular to the extension direction of the horizontal transfer guide rail.

[0004] Based on the above scheme, the longitudinal support frame is provided with a position calibration slot on the side facing the transfer mechanism. There are multiple position calibration slots, and each slot corresponds to a storage tray. The relative position of the position calibration slot to each storage tray is consistent. The transfer mechanism includes a distance sensor, which is fixedly connected to the moving frame. The distance sensor is used to detect the distance between itself and the position calibration slot, and the distance sensor is communicatively connected to the power device that drives the sliding frame.

[0005] Based on the above scheme, the position calibration groove is an inverted T-shaped structure, including a transverse calibration groove extending in the vertical direction and a longitudinal calibration groove extending in the horizontal direction, with the bottom of the transverse calibration groove located in the middle of the longitudinal calibration groove.

[0006] Preferably, the material handling mechanism includes a fixed connecting frame, a primary sliding frame, and a secondary sliding frame. The fixed connecting frame is fixedly connected to the movable frame, and the upper surface of the secondary sliding frame is flat. A primary drive gear is rotatably connected to the fixed connecting frame, and the primary drive gear rotates in a vertical plane. A primary rack is fixedly connected to the primary sliding frame on the side facing the fixed connecting frame, and the primary rack extends along the moving direction of the primary sliding frame, with the primary drive gear meshing with the primary rack. A secondary drive gear is rotatably connected to the primary sliding frame, and the secondary drive gear rotates in a vertical plane. A secondary rack is fixedly connected to the secondary sliding frame on the side facing the primary sliding frame, and the secondary rack is parallel to the primary rack and extends along the moving direction of the secondary sliding frame, with the secondary drive gear meshing with the secondary rack.

[0007] Based on the above scheme, the fixed connecting frame includes two vertically arranged and relatively parallel connecting plates, a primary drive gear is connected between the two connecting plates, a primary sliding frame is arranged above the fixed connecting frame, the primary sliding frame extends downward in the outer area of ​​the fixed connecting frame and bends to form a primary sliding groove, a connecting frame pulley is rotatably arranged on the fixed connecting frame in the horizontal direction, the connecting frame pulley rotates in the vertical plane, the connecting frame pulley is arranged on the opposite outer side of the connecting plate, and the connecting frame pulley is rotatably engaged in the primary sliding groove.

[0008] Preferably, the secondary sliding frame is disposed above the primary sliding frame, and the bottom of the secondary sliding frame is fixedly connected to the secondary connecting frame in the outer area of ​​the primary sliding frame. The secondary connecting frame is rotatably connected to the secondary pulley, which rotates in the vertical plane. The primary sliding frame is recessed inward on the side facing the secondary connecting frame to form a secondary sliding groove, and the secondary pulley is rotatably engaged in the secondary sliding groove.

[0009] Preferably, a primary drive motor is connected to the fixed connecting frame, and the primary drive motor drives the primary drive gear to rotate; a secondary drive motor is connected to the primary sliding frame, and the secondary drive motor drives the secondary drive gear to rotate; it also includes a distance sensor, the distance sensor being fixed in relative position to the fixed connecting frame, and the distance sensor being communicatively connected to the primary drive motor and the secondary drive motor.

[0010] Preferably, the storage tray is detachably mounted on a longitudinal support frame.

[0011] Preferably, it also includes a transfer buffer mechanism, which includes a buffer frame, a buffer conveyor belt, a buffer positioning motor, and a buffer clamping plate. The buffer conveyor belt circulates on the buffer frame, and buffer tray supports overlap the bottom of the buffer tray on the buffer conveyor belt. The buffer positioning motors are arranged in pairs on both sides of the buffer conveyor belt in the conveying direction. The buffer positioning motors drive the buffer clamping plate to move in the horizontal plane in a direction perpendicular to the buffer conveyor belt. Buffer guide blocks are fixedly connected to the relatively inner sides of the buffer clamping plates, and buffer positioning grooves are formed on the outer sides of the buffer guide blocks. When the buffer clamping plates move relatively inward to the clamping position, the buffer tray supports are engaged in the buffer positioning grooves. When the buffer clamping plates move relatively outward to the releasing position, the buffer tray supports are released from the buffer positioning grooves.

[0012] Based on the above scheme, there are multiple buffer guide blocks, which are arranged in parallel along the direction of movement of the buffer conveyor belt in the horizontal plane. The buffer positioning slots are located between adjacent buffer guide blocks and at the outer edge of the outermost buffer guide block.

[0013] The beneficial effects of this utility model are as follows: Each storage pallet in the warehouse rack is equipped with a fixed position calibration slot. By detecting the position of the position calibration slot, the actual position of the corresponding storage pallet can be determined. When picking up, placing and transferring, the operation is carried out according to the actual position, which effectively avoids the error in operation distance caused by the tilt of the warehouse rack. The transfer mechanism enables the material handling mechanism to move within space, satisfying material handling and transfer operations at different locations. Through a two-stage sliding mechanism, the material handling mechanism meets two different transfer needs: short-distance small-sized workpieces and tooling, and long-distance large-sized workpieces and tooling. When transferring short-distance or small-sized workpieces and tooling, only the second-stage sliding frame or the first-stage sliding frame moves. When transferring long-distance or large-sized workpieces and tooling, both the first-stage and second-stage sliding frames extend together, which is equivalent to doubling the stroke of the bearing device based on the fixed connecting frame, thereby meeting the needs of different sizes and transfer distances. A transfer buffer mechanism is set up to meet the temporary storage needs before workpieces are loaded for processing, and to position the temporarily stored parts and tooling to meet the position requirements of the parts in subsequent processing and loading operations.

[0018] like Figure 1 As shown, a large-capacity parts storage system includes storage racks for storing parts and a transfer mechanism for moving parts.

[0019] like Figure 1 and Figure 2 As shown, the storage rack includes multiple vertically arranged longitudinal support frames 31, which are arranged in two parallel rows. Each row contains multiple longitudinal support frames 31 that are parallel to each other in the vertical plane. The longitudinal support frames 31 in the two rows are arranged in pairs, and a storage tray 33 for placing parts or tooling is provided between each pair of longitudinal support frames 31. The storage tray 33 has a planar structure. A horizontal loading crossbeam 32 is fixedly connected to each row of longitudinal support frames 31, forming a loading channel between the loading crossbeams 32 of the two rows of longitudinal support frames 31. This loading channel can be used in conjunction with the loading device 11 in the upstream process. After the tooling tray 15 and the parts on it are transported by the loading device into the loading channel, they are supported by a transfer mechanism and placed on storage trays 33 at different positions on the storage rack. Tray legs 151 are fixedly connected to the bottom of the tooling tray 15, forming an operating space for support at the bottom of the tooling tray 15.

[0020] Preferably, the storage tray 33 is detachably mounted on the longitudinal support frame 31 to facilitate the removal and replacement of individual storage trays 33. Specifically, positioning blocks 331 protrude outward from opposite sides of the storage tray 33. The positioning blocks 331 engage with vertical grooves on opposite inner sides of the longitudinal support frame 31 to provide positioning. Vertical mounting grooves are provided on the longitudinal support frame 31. Mounting blocks 332 are fixedly connected to the outer side of the positioning blocks 331. The mounting blocks 332 engage with the mounting grooves on the corresponding sides to complete the installation of the storage tray 33.

[0021] like Figure 3 As shown, the transfer mechanism is located on one side of the storage rack. The transfer mechanism includes a horizontal transfer guide rail 41, a vertical transfer guide rail 42, a movable frame 43, and a material handling mechanism 45. The horizontal transfer guide rail 41 is parallel to the loading crossbeam 32, and the vertical transfer guide rail 42 is parallel to the longitudinal support frame 31. The vertical transfer guide rail 42 is slidably mounted on the horizontal transfer guide rail 41. The movable frame 43 is slidably mounted on the vertical transfer guide rail 42. The material handling mechanism 45 is fixedly connected to the movable frame 43, and the material handling mechanism 45 includes a sliding frame that moves perpendicular to the extension direction of the horizontal transfer guide rail 41 in the horizontal plane. This structure enables the material handling mechanism 45 to move over a wide range in space, thereby allowing material transfer at different locations.

[0022] like Figures 3 to 6As shown, the material handling mechanism 45 includes a fixed connecting frame 461, a primary sliding frame 471 and a secondary sliding frame 481. The fixed connecting frame 461 is fixedly connected to the moving frame 43. The upper surface of the secondary sliding frame 481 is flat and is used to support the workpiece or tooling.

[0023] A primary drive gear 462 is rotatably connected to the fixed connecting frame 461. The primary drive gear 462 rotates in a vertical plane. A primary sliding frame 471 is fixedly connected to a primary rack 472 on the side facing the fixed connecting frame 461. The primary rack 472 extends along the moving direction of the primary sliding frame 471, and the primary drive gear 462 meshes with the primary rack 472. The rotation of the primary drive gear 462 drives the primary rack 472 and the primary sliding frame 471 to move relative to the fixed connecting frame 461. Preferably, there are multiple primary drive gears 462, arranged parallel to the primary rack 472, with adjacent primary drive gears 462 meshing with each other. Each primary drive gear 462 meshes with the primary rack 472, improving driving capability and supporting the primary sliding frame 471 at different positions.

[0024] A secondary drive gear 473 is rotatably connected to the primary sliding frame 471. The secondary drive gear 473 rotates in a vertical plane. A secondary rack (not shown in the figure) is fixedly connected to the secondary sliding frame 481 facing the primary sliding frame 471. The secondary rack is parallel to the primary rack 472 and extends along the moving direction of the secondary sliding frame 481. The secondary drive gear 473 meshes with the secondary rack. The rotation of the secondary drive gear 473 drives the secondary rack and the secondary sliding frame 481 to move relative to the primary sliding frame 471. There are two secondary drive gears 473, which are located diagonally opposite each other on the primary sliding frame 471. Correspondingly, there are also two secondary racks to balance the supporting force of the secondary drive gears 473 on the secondary sliding frame 471.

[0025] The fixed connecting frame 461 is connected to a primary drive motor 463, which drives the primary drive gear 462 to rotate; the primary sliding frame 471 is connected to a secondary drive motor, which drives the secondary drive gear 473 to rotate.

[0026] Preferably, the fixed connecting frame 461 includes two vertically arranged and relatively parallel connecting plates. A primary drive gear 462 is connected between the two connecting plates. A primary sliding frame 471 is arranged above the fixed connecting frame 461. The primary sliding frame 471 extends downward in the outer region of the fixed connecting frame 461 and is bent to form a primary sliding groove. The primary sliding groove is a U-shaped groove that opens to one side of the connecting plate. A connecting frame pulley 464 is rotatably arranged on the fixed connecting frame 461 in the horizontal direction. The connecting frame pulley 464 rotates in the vertical plane and is arranged on the opposite outer side of the connecting plate. The connecting frame pulley 464 is rotatably engaged in the primary sliding groove. On the one hand, it supports the primary sliding frame 471, and on the other hand, it modifies the sliding friction between the primary sliding frame 471 and the fixed connecting frame 461 into rolling friction, which greatly reduces the frictional resistance. Preferably, there are multiple connecting frame pulleys 464 on each side connecting plate, and they are arranged in a direction parallel to the first-stage rack 472 to provide uniform support for different positions of the first-stage sliding frame 471.

[0027] Preferably, the secondary sliding frame 481 is disposed above the primary sliding frame 471. The bottom of the secondary sliding frame 481 is fixedly connected to the secondary connecting frame 482 in the outer region of the primary sliding frame 471. The secondary connecting frame 482 is rotatably connected to the secondary pulley 483, which rotates in the vertical plane. The primary sliding frame 471 is recessed inward on the side facing the secondary connecting frame 482 to form a secondary sliding groove. The secondary sliding groove is a U-shaped groove with a horizontally outward opening. The secondary pulley 483 is rotatably engaged in the secondary sliding groove, which on the one hand supports the secondary sliding frame 481, and on the other hand modifies the sliding friction between the secondary sliding frame 481 and the primary sliding frame 471 into rolling friction, greatly reducing frictional resistance. Preferably, the secondary connecting frame 482 and the secondary sliding groove are respectively arranged on both sides of the secondary sliding frame 481 and the primary sliding frame 471. Multiple secondary pulleys 483 are connected to each secondary connecting frame 482 and arranged in a direction parallel to the secondary rack. This is used to evenly support different positions of the secondary sliding frame 481.

[0028] The outer side of the primary sliding frame 471 is rotatably connected to a supporting pulley 474, which rotates in a vertical plane. The upper part of the supporting pulley 474 abuts against the lower edge of the secondary connecting frame 482 and rotates relative to the secondary connecting frame 482, thereby supporting the secondary connecting frame 482 and the secondary sliding frame 481 and reducing friction. The lower edge of the secondary connecting frame 482 is rotatably connected to a limiting pulley 484, which rotates in a horizontal plane. The side of the limiting pulley 484 near the primary sliding frame 471 abuts against the outer edge of the primary sliding frame 471 and rotates relative to the primary sliding frame 471, thereby limiting the relative positional relationship between the secondary sliding frame 481 and the primary sliding frame 471.

[0029] When picking up and transferring materials, the two orthogonal guide rails of the transfer mechanism drive the material picking and placing mechanism 45 to move to the target position of the feeding channel or storage pallet 33. The first-stage drive motor 463 and the second-stage drive motor are activated, driving the sliding frame to extend to one side of the storage rack until it enters the operating space below the tooling pallet 15. The moving frame 43 drives the material picking and placing mechanism 45 to move upward, taking the tooling pallet 15 away from the feeding channel or storage pallet 33. The moving frame 43 drives the tooling pallet 15 to move in the opposite direction to outside the storage rack. Then, according to the process flow requirements, the tooling pallet 15 is transferred to the target storage pallet 33, or moved in the opposite direction to the processing machine tool and other target positions on the opposite side of the storage rack.

[0030] To ensure accurate target positioning and prevent errors due to storage rack offset, the longitudinal support frame 31 is provided with position calibration slots 34 facing the transfer mechanism. Multiple position calibration slots 34 are provided, each corresponding to a storage pallet 33, and their relative positions are consistent. The transfer mechanism includes a distance sensor 44, which is fixedly connected to the moving frame 43. The distance sensor 44 detects the distance between itself and the position calibration slot 34 and is communicatively connected to the power unit driving the sliding frame, specifically to the primary drive motor 463 and the secondary drive motor. The position calibration slots 34 can be located above or below the corresponding storage pallet 33. Each position calibration slot 34 has an inverted T-shaped structure, including a transverse calibration slot 341 extending vertically and a longitudinal calibration slot 342 extending horizontally. The bottom of the transverse calibration slot 341 is located in the middle of the longitudinal calibration slot 342. During position calibration, the material handling mechanism 45 is first moved to the theoretically predetermined position. Then, the moving frame 43 drives the distance sensor 44 to move horizontally. When it moves to the horizontal calibration slot 341, a falling edge signal is detected, proving that the horizontal movement is in place. Then, the moving frame 43 drives the distance sensor 44 to move vertically. When it moves to the vertical calibration slot 342, a falling edge signal is detected, proving that the vertical movement is in place, and the sliding frame can be driven to perform material handling.

[0031] Furthermore, to meet the temporary storage needs before parts are loaded and processed, a transfer buffer mechanism is also included, which includes a buffer rack 51, a buffer conveyor belt 52, a buffer positioning motor 54 and a buffer clamping plate 55. The tooling pallet 15 from the storage rack is transferred to the transfer buffer mechanism as a buffer pallet 53, and the pallet support 151 is referred to here as the buffer pallet support 531. The buffer conveyor belt 52 circulates on the buffer rack 51. The buffer pallet support legs 531 at the bottom of the buffer pallet 53 overlap the buffer conveyor belt 52. The buffer positioning motors 54 are arranged in pairs on both sides of the buffer conveyor belt 52 in the conveying direction. The buffer positioning motors 54 drive the buffer clamping plates 55 to move in the horizontal plane in a direction perpendicular to the buffer conveyor belt 52. The buffer guide blocks 551 are fixedly connected to the inner side of the buffer clamping plates 55. The outer side of the buffer guide blocks 551 forms a buffer positioning groove 552. There are multiple buffer guide blocks 551, which are arranged in parallel in the horizontal plane in the direction of movement of the buffer conveyor belt 52. The buffer positioning groove 552 is located between adjacent buffer guide blocks 551 and at the outer edge of the outermost buffer guide block 551.

[0032] When the buffer clamping plate 55 moves inward to the clamping position, the buffer tray support legs 531 engage in the buffer positioning groove 552 to determine the relative position of the buffer tray 53 and the buffer conveyor belt 52. This engagement can be achieved through the buffer positioning groove 552 between adjacent buffer guide blocks 551, or through the outer edge of the outermost buffer guide block 551. When the buffer clamping plate 55 moves outward to the releasing position, the buffer tray support legs 531 disengage from the buffer positioning groove 552, allowing the buffer tray 53 to continue moving with the buffer conveyor belt 52.

[0033] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
