Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent warehousing, and in particular relates to a stacker and an intelligent warehousing device for parts. Background Art

[0002] In the domestic aircraft maintenance industry, the wings of aircraft are generally laid flat (the larger aircraft wings are 7.5 meters × 3.5 meters, and the smaller ones are 1 meter × 3 meters), which occupies a large area, is very difficult to transport, and has a low level of intelligence.

[0003] In order to facilitate the transfer of aircraft parts to the workstations in the operation room, the operation room can only be set up on the first floor. The area of ​​the operation room is limited and there are relatively few operation stations. After the parts are repaired, the parts need to be transferred out in time, which still occupies a large storage space. In addition, a certain amount of transfer space is still required between parts, which increases the area occupied by parts storage. Finding and transferring parts often requires a long distance and a long time.

[0004] The same problem exists not only in the aircraft maintenance industry, but also in the storage and maintenance of parts in industries such as automobiles and trains. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects in the prior art that parts stored flat on the ground occupy a large area and are inconvenient to access, and to provide a parts storage stacker and a parts intelligent storage device that occupy a small space and are convenient for transportation.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] The present invention discloses a stacker, which is characterized by comprising a loading platform, push-pull guide rails which are consistent with the storage and retrieval direction of the stacker are arranged at both ends of the loading platform, a push-pull motor is slidably connected to the push-pull guide rails, the push-pull motor is a shaftless motor, the output end of which is a push-pull nut, the push-pull nut is spirally sleeved on a push-pull lead screw, both ends or one end of the push-pull lead screw is rotatably mounted on the loading platform through bearings; a push-pull cross bar which is arranged parallel to the push-pull guide rail is fixedly mounted on the outer shell of the push-pull motor, and an electric latch is installed on the push-pull cross bar.

[0008] Preferably, an optical camera is also installed on the push-pull cross bar.

[0009] Preferably, detection rods are respectively installed at the four corners of the loading platform, and a large tray detection sensor for detecting whether the large tray has completely entered the loading platform is installed at the lower part of the detection rod.

[0010] Preferably, a component detection sensor for detecting whether there are components on the large tray is installed on the upper part of the detection rod.

[0011] Preferably, both ends of the push-pull cross bar are provided with an electric latch and an optical camera.

[0012] The present invention also discloses an intelligent storage device for parts, which is characterized by: comprising the above-mentioned stacker and shelves arranged on one side or both sides of the stacker; the stacker and the shelves are located in the storage room, and the parts are located in the operating room adjacent to the storage room, and a connecting window is provided between the storage room and the operating room, and an in-and-out storage connecting rack penetrates the connecting window and is horizontally connected to a certain shelf of the shelf; the parts are placed on a large pallet, and the large pallet has push-pull holes corresponding to the electric latch; an unpowered roller line is installed on the shelf, and the large pallet storing the parts is placed on the in-warehouse connecting rack, and the large pallet is pulled onto the loading platform for storage after the push-pull cross bar is moved and the electric latch is inserted into the push-pull hole.

[0013] Preferably, a non-powered roller line is also installed on the storage connecting frame.

[0014] Preferably, the operation room has at least two floors, and there is a connecting window between the operation room and the storage room on each floor.

[0015] Preferably, the large pallet includes: transverse main beams and longitudinal main beams vertically overlapped to form a rectangular shape, and load-bearing beams are also overlapped between the transverse main beams or the longitudinal main beams; TPR material is laid on the load-bearing beams; and the transverse main beams have a plurality of push-pull holes for docking with a stacker.

[0016] More preferably, a concave surface corresponding to the convex surface of the component is processed on the large tray; the outer edge of the component is also provided with a protective frame that fits therewith; and the curved shape of the protective frame is consistent with the outer edge of the component.

[0017] Compared with the prior art, the stacker and the intelligent storage device for parts of the present invention have the following beneficial effects:

[0018] 1. The push-pull motor of the stacker adopts a shaftless motor, and the output end is a push-pull nut. The shell of the push-pull motor directly serves as the slider in the ball screw nut transmission, and the push-pull nut serves as the nut in the ball screw nut. There is no motor at the end of the push-pull screw, so that the push-pull motor can move to both ends of the loading platform to the maximum extent, maximizing the stroke of the push-pull crossbar and reducing the width of the stacker.

[0019] 2. The optical camera detects the push-pull holes on the large pallet, and then the electric latch is inserted into the push-pull holes to pull the large pallet onto the loading platform. This method is safe and simple, and is especially suitable for the storage of larger parts. Compared with ordinary stackers that use forks to carry parts into the warehouse, the load-bearing capacity of the larger loading platform is safe and reliable, and the parts are not touched during the storage process to avoid damage to the parts.

[0020] 3. The intelligent storage device for parts stores parts on multi-layer shelves through stackers, which greatly reduces the floor space occupied by parts storage; the storage room and the operation room are separated and set adjacent to each other, and the transfer of parts from the shelves to the operation room is achieved through connecting windows.

[0021] 4. The operation room can be divided into multiple layers according to the height of the shelves, which greatly reduces the overall floor space of the operation room, increases the number of maintenance operation stations, and improves maintenance efficiency.

[0022] 5. The parts are placed on large pallets for entering and leaving the warehouse. The large pallets are processed with concave surfaces corresponding to the convex surfaces of the parts to prevent the parts from sliding easily. In addition, a protective frame that fits the outer edge of the parts is also provided to protect the outer edge of the parts from being damaged by collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] like Figure 1-Figure 7 The specific embodiment of the intelligent storage device for parts of the present invention shown in the figure is mainly used for the storage of parts of aircraft, automobiles, trains, etc. This embodiment takes the storage of aircraft parts as an example. Figure 1 and Figure 2 The intelligent storage device for parts includes: a factory building, shelves 3 and a stacker 2. The factory building includes an operation room 12 and a storage room 13. In this embodiment, the shelves 3 are arranged in two rows in parallel, and a single row of shelves 3 can also be arranged as needed. The shelves 3 are arranged close to the wall of the storage room 13. The storage room 13 can be arranged in the middle as needed, and the operation rooms 12 can be arranged on both sides, or on one side. Figure 1 The stacker 2 moves between two rows of shelves 3 guided by the ceiling rail 210 and the floor rail 211, and stores or takes goods from the shelves 3. The shelves 3 and the stacker 2 are located in the storage room 13. The operation room 12 can be divided into multiple layers according to the height of the factory building and the height of the stacker 2. In this embodiment, it is divided into two layers of operation rooms 12, namely the first-floor operation room and the second-floor operation room. There are connecting windows 15 between the first-floor operation room and the second-floor operation room and the storage room 13. A storage-in and storage-out connecting frame 1 passes through the connecting window 15 and is horizontally connected to a certain layer of shelves 31 on the shelves 3. There should be a connecting window 15 between each layer of the operation room 12 and the storage room 13 to realize the storage and out of the parts 16.

[0034] The shelves 3 are higher than the connecting window 15 of the second-floor operating room. A non-powered roller line 11 is installed on each layer of the shelf 31 to facilitate the entry and exit of goods. The entry and exit methods in each operating room 12 are the same. Here, the second floor is taken as an example.

[0035] Aircraft parts 16 need to be placed on pallets when entering and leaving the warehouse. The pallets are divided into large pallets 4 and small pallets 17. A large pallet 4 is placed on each shelf 31. For large parts 16, one large pallet 4 can hold one part, and for small parts 16, one large pallet can hold multiple parts 16; two small pallets 17 can be placed on a large pallet 4, and small parts 16 of the aircraft are placed on the small pallet 17. The pallet has a pallet code, and the aircraft parts have a product code. The system recognizes their identity characteristics by scanning the code.

[0036] Each component of the outer wing, vertical tail and horizontal tail of the aircraft is placed on a large tray 4, and the rudder, downward vertical tail, flaperon, front door, speed brake, leading edge flap, leading edge flap second section, main wheel bay door and landing gear rear door are placed on a small tray 17.

[0037] See also Figure 3 The large pallet 4 includes a transverse main beam 42 and a longitudinal main beam 43 which are overlapped vertically to form a rectangular shape. A load-bearing beam 44 is overlapped between the transverse main beams 42 or the longitudinal main beams 43. The transverse main beams 42 and the longitudinal main beams 43 are made of steel. The lower layer of the load-bearing beam 44 can be made of softer pine wood or harder iron wood, because wood is easier to process. The upper layer of the load-bearing beam 44 is made of TPR material, which is directly laid on the wood. This material is economical, wear-resistant, non-slip, flexible, and shock-absorbing. There are multiple push-pull holes 41 on the transverse main beam 42 for docking with the stacker 2.

[0038] See also Figure 6 The size of the small tray 17 is ≤ 1 / 2 of the size of the large tray 4, and it is also made of overlapped steel, and a flexible TPR material is laid where it contacts the parts 16. Two small trays 17 can be placed on each large tray 4.

[0039] Since the outer surfaces of the outer wing, vertical tail and horizontal tail have curvature, the convex surface of the component 16 can be used as a reference to process a concave surface corresponding to the convex surface of the component 16 on the wood layer of the pallet. The combination of the convex surface of the part and the concave surface of the pallet allows the aircraft component 16 to be stored on the pallet for a long time without deformation. Figure 7 A protective frame 14 that fits the component 16 can be sleeved on the outer edge of the component 16 , and the curved shape of the protective frame 14 is consistent with the outer edge of the component 16 .

[0040] The small tray 17 has good compatibility. The components 16 are manually placed on the small tray 17 . The components 16 need to be separated by flexible materials and manually bound with safety ropes.

[0041] See also Figure 5 The shelves 3 are welded shelves 3 and are bolted with I-beams. Each shelf 31 includes a longitudinal plate 32 and a plurality of non-powered roller lines 11 fixed on the upper surface of the longitudinal plate 32. Fire protection installation space and maintenance space are reserved on the shelves 3. In order to prevent the pallet from sliding in the warehouse, a damping device is installed at the end where the non-powered roller line 11 is connected to the stacker 2 to ensure that the pallet will not slide on the shelf 31 by itself.

[0042] See also Figure 1 The stacker 2 includes: two parallel ground rails 211 arranged on the ground, two ceiling rails 210 arranged on the ceiling of the storage room 13 and parallel to the ground rails 211, a lower base frame 212 slidably connected to the ground rails 211, two parallel columns 213 vertically installed on the lower base frame 212, a loading platform 20 moving up and down along the columns 213, a lifting motor 214 for driving the loading platform 20 to rise and fall, and an upper connecting frame 215 arranged at the top of the column 213 and slidably connected to the ceiling rails 210; the lifting motor drives the loading platform 20 to move up and down through a chain, a moon ladder 216 is installed on the outer side of the column 213 and connected to a high-position maintenance platform 217 close to the position of the ceiling rails 210, and limit switches 218 are provided at both ends of the ground rails 211 to limit the stacker 2.

[0043] In this embodiment, there are four columns 213, each of which is fixedly mounted with a vertical guide rail 219. The sides of the loading platform 20 opposite to the vertical guide rail 219 are provided with a lifting slider 220, and the lifting slider 220 has two rows of symmetrically arranged pulleys, which clamp the vertical guide rail 219 and roll along the vertical guide rail 219.

[0044] See also Figure 4 , push-pull guide rails 21 are provided at both ends of the loading platform 20 in the same direction as the stacker 2 for storing and retrieving goods, and a push-pull motor 22 is slidably connected to the push-pull guide rails 21. The push-pull motor 22 is a shaftless motor, and its output end is a push-pull nut, which is spirally sleeved on a push-pull lead screw 23, and both ends or one end of the push-pull lead screw 23 are rotatably mounted on the loading platform 20 through bearings. The embodiment of the present invention adopts a shaftless bidirectional rotating motor, and the motor itself is a slider, so as to avoid the push-pull motor 22 being fixedly arranged at one end of the push-pull lead screw 23, which affects the bidirectional retrieval of the stacker 2.

[0045] A push-pull cross bar 24 parallel to the push-pull guide rail 21 is fixedly mounted on the push-pull motor 22, and an electric latch 25 and an optical camera 26 are mounted on both ends of the push-pull cross bar 24. When the pallet is completely on the loading platform 20, the initial position of the push-pull motor 22 is located in the middle of the loading platform 20. When the push-pull motor 22 picks up goods from the shelves 3 on the left and right sides, the number of rotations of the push-pull motor 22 is generally within a range according to the size of the pallet and the distance between the push-pull motor 22 and the shelf 3. In this way, the control system can set a maximum number of rotations for the push-pull motor 22 to prevent the push-pull motor 22 from excessive movement and damage to other components 16.

[0046] The loading platform 20 also has a non-powered roller line 11. The four corners of the loading platform 20 are respectively equipped with detection rods 27. A large tray detection sensor 28 is installed at the lower part of the detection rod 27 to ensure that the tray enters the loading platform 20 completely to prevent it from slipping. A parts detection sensor is installed at the upper part of the detection rod 27 to ensure that there are parts 16 on the large tray 4, rather than an empty tray entering the warehouse.

[0047] When the stacker 2 needs to pick up goods from the shelf 3, the push-pull motor 22 is started to move the push-pull cross bar 24 toward the shelf 3 where the goods need to be picked up. Here, taking the goods from the shelf 3 on the right as an example, the push-pull motor 22 drives the push-pull cross bar 24 to move to the right, and the optical camera 26 on the push-pull cross bar 24 detects the push-pull holes 41 on the large pallet 4. When it moves to a certain position, the optical camera 26 detects that the electric latch 25 is just above a suitable push-pull hole 41, and the control system controls the electric latch 25 to move downward into the push-pull hole 41, and then pushes the electric latch 25 to move to the right. The pulling motor 22 moves in the opposite direction and pulls the large pallet 4 onto the loading platform 20. When the large pallet 4 detection sensor 28 on the right side receives no photoelectric signal, it indicates that the large pallet 4 begins to enter the loading platform 20. When the large pallet 4 detection sensor 28 on the right side receives the photoelectric signal again, it indicates that the large pallet 4 has completely entered the loading platform 20. At the same time, the large pallet 4 detection sensor 28 on the left side can receive the photoelectric signal, indicating that the left side of the large pallet 4 does not exceed the loading platform 20. The push-pull motor 22 stops rotating and the stacker 2 completes one pick-up from the shelf 3.

[0048] The specific working process of the parts intelligent storage device of the embodiment of the present invention is as follows:

[0049] A large pallet 4 carrying aircraft parts 16 is placed on the warehousing connecting rack 1, and slides into the shelf 31 connected to the warehousing connecting rack 1 through the unpowered roller 11 on the warehousing connecting rack 1, and the damping device at the end of the shelf 31 prevents the large pallet 4 from sliding in the warehouse. The control system sends a warehousing command to the stacker 2, and the loading platform 20 of the stacker 2 moves to the shelf 31 at the warehousing position. The push-pull motor 22 starts and drives the push-pull cross bar 24 to move. The electric latch 25 moves to the appropriate position and is inserted into the push-pull hole 41 of the large pallet 4, pulling the large pallet 4 onto the loading platform 20. Then the stacker 2 moves the parts 16 to the corresponding shelf 31 according to the warehousing information sent by the control system.

[0050] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
