Description

Technical Field

[0001] The present invention relates to the field of warehousing technology, and in particular to an intelligent and efficient warehousing system. Background Art

[0002] Shuttle warehousing is an important component of modern logistics and storage industries. Current shuttle warehousing generally includes shelves, shuttles, elevators or stackers. Storing and retrieving goods generally requires a shuttle to place the goods on a certain shelf to a designated location, and an elevator or stacker to transport the goods to shelves at different heights.

[0003] With the development of society, the production volume is also increasing. The storage system needs to prepare a large number of shelves to place different goods. When the existing stacker loads and unloads goods from the shelves, it first uses a shuttle car to reach the designated position to transfer the goods to the stacker, and then the stacker moves and lifts to transfer the goods to the shelves. Since the stacker moves slowly when loaded, the efficiency of the storage system is low and cannot meet the current storage and transportation requirements. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent and efficient storage system to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent and efficient storage system, comprising a plurality of warehouse mechanisms, the warehouse mechanism being composed of four rows of shelves arranged in a longitudinal direction and arranged in a transverse manner, the shelves being composed of a plurality of U-shaped support frames extending downward and arranged in a longitudinal direction, and each U-shaped support frame being fixedly connected by a plurality of support plates, the support plates being used to place goods, the two middle rows of shelves being closely connected, and the U-shaped support frames of the two outer rows of shelves forming a transfer area with the ground;

[0006] Several stackers, at least two of which are provided in each warehouse unit, installed between the outer shelves and the shelves adjacent to them, used to lift goods to the upper shelves, and can slide longitudinally;

[0007] A plurality of transfer tracks, at least one of which passes through the transfer area longitudinally and is laterally connected at both ends of the first shelf and the fourth shelf to form a circular circulation track;

[0009] Several shuttles, with at least one shuttle being arranged on each of the transfer track and the conveying track;

[0010] The stacker and shuttle are both equipped with a transfer mechanism capable of transferring goods and a position sensor for positioning.

[0011] Furthermore, the transfer mechanism includes a conveying frame, a chain, a transfer reduction motor, a cargo guide plate and a limit plate. Two rollers are provided at both ends of the conveying frame. The chain connects the rollers and the transfer reduction motor through a chain drive. The cargo guide plates are installed on both sides of the conveying frame, and the limit plate is fixed at the rear end of the conveying frame.

[0012] Furthermore, the shuttle car also includes a driving mechanism for driving the shuttle car to move along the transfer track or the conveying track, the driving mechanism includes two sets of driving wheel devices and two sets of driven wheel devices, the driving wheel device includes a driving wheel mounting seat, a driving wheel seat and a driving reduction motor, a driving roller is arranged on the inner side of the driving wheel mounting seat, the driving wheel seat is rotatably arranged on the top of the driving wheel mounting seat, the driving reduction motor is mounted on the outer wall side of the driving wheel mounting seat, and the transmission end of the driving reduction motor is penetrated through the driving wheel mounting seat to connect the driving roller, the driven wheel device includes a driven wheel mounting seat, a driven wheel seat and a secondary wheel swing arm, a driven guide rail wheel is rotatably mounted on the inner side of the driven wheel mounting seat, two ends of the secondary wheel swing arm are respectively hinged to the driven wheel mounting seat and the driven wheel seat, the front and rear ends of the driving wheel mounting seat and the driven wheel mounting seat are fixed with guide wheel seats, a deep groove ball is arranged below the guide wheel seat, and the deep groove ball is rotatably connected to the guide wheel seat.

[0032] Two conveying tracks 4 are respectively arranged at the head end and the tail end of the warehouse mechanism and are parallel to the transverse arrangement of the transfer track 3;

[0033] A plurality of shuttle vehicles 5, at least one shuttle vehicle 5 is respectively arranged on the transfer track 3 and the conveying track 4;

[0034] The stacker 2 and the shuttle 5 are both equipped with a transfer mechanism for transferring goods and a position sensor for positioning.

[0035] As mentioned above, during the operation of the warehousing system, a transfer area is designed under the shelf 1, and a transfer track 3 passes through the transfer area. The stacker 2 receives the signal and moves first to the bottom of the side where the shelf 1 is placed, and the shuttle 5 on the conveying track 4 transfers the goods to the shuttle 5 on the transfer track 3. The shuttle 5 on the transfer track 3 moves to the bottom of the shelf 1, and the shuttle 5 on the transfer track 3 then transfers the goods to the stacker 2. The existing stacker 2 needs to receive the goods at a specific position, and then move to the bottom of the shelf 1 for lifting. Since the stacker 2 receives the signal and moves first, the moving time of the slow-moving stacker 2 is reduced, thereby speeding up the efficiency.

[0036] In this embodiment, refer to Figure 5 The transfer mechanism includes a conveyor frame 61, a chain 62, a reduction motor, a cargo guide plate 64 and a limit plate 65. Two rollers 66 are arranged at both ends of the conveyor frame 61. The chain 62 is connected to the roller 66 and the second reduction motor through a chain drive. The cargo guide plate 64 is installed on both sides of the conveyor frame 61. The limit plate 65 is fixed to the rear end of the conveyor frame 61. The reduction motor drives the chain 62 to move it, driving the cargo to move to another transfer mechanism or the shelf 1 to realize cargo transfer.

[0037] In this embodiment, refer to Figure 6, 7 , 8 and 9, the shuttle 5 also includes a driving mechanism for driving the shuttle 5 to move along the transfer track 3 or the conveying track 4, the driving mechanism includes two sets of driving wheel devices and two sets of driven wheel devices, the driving wheel device includes a driving wheel mounting seat 71, a driving wheel seat 72 and a driving reduction motor 73, a driving roller 74 is arranged on the inner side of the driving wheel mounting seat 71, the driving wheel seat 72 is rotatably arranged on the top of the driving wheel mounting seat 71, the driving reduction motor 73 is mounted on the outer wall side of the driving wheel mounting seat 71, and the transmission end of the driving reduction motor 73 passes through the driving wheel mounting seat 71 to connect the driving roller 74, the driven wheel device includes a driven wheel mounting seat 75, a driven wheel seat 76 and auxiliary wheel swing arm 77, a driven guide wheel 78 is rotatably installed on the inner side of the driven wheel mounting seat 75, and the two ends of the auxiliary wheel swing arm 77 are respectively hinged to the driven wheel mounting seat 75 and the driven wheel seat 76, and the front and rear ends of the driving wheel mounting seat 71 and the driven wheel mounting seat 75 are fixed with a guide wheel seat 79, and a deep groove ball 80 is arranged below the guide wheel seat 79, and the deep groove ball 80 is rotatably connected to the guide wheel seat 79, and is directly connected to the active roller wheel 74 by driving the reduction motor 73, and the wheel pressure is increased to increase the friction of the active roller wheel 74, thereby improving the walking speed of the shuttle car 5. During transportation, the active roller wheel 74 can travel quickly on the track, thereby accelerating the transportation speed of the warehousing system.

[0038] In this embodiment, refer to Figure 2 The top and bottom of the stacker 2 are slidably connected to a linear guide rail 81 arranged along the longitudinal direction, wherein the linear guide rail 81 at the top is fixedly connected to a support rod arranged along the transverse direction, and both ends of the support rod are fixedly connected to a ground beam, so that the stacker 2 is more stable and the load capacity of the stacker 2 is increased.

[0039] In this embodiment, refer to Fig.10, also includes an infrared transmitter, an infrared receiver and a central system. The shuttle 5 is equipped with an infrared transmitter, and the shelf 1, the stacker 2 and the position between the transfer track 3 and the conveying track 4 are equipped with infrared receivers. The central system is electrically connected to the stacker 2, the shuttle 5, the infrared receiver and the position sensor respectively. Through the rapid recognition function of the infrared transmitter and the infrared receiver, the storage system is intelligent and the efficiency of the storage system is improved. During the storage of goods, when the shuttle 5 on the conveying track 4 is loaded with goods, the central system detects that the shuttle 5 on the conveying track 4 is moving through the position sensor, and then moves the shuttle 5 on the transfer track 3 to the side of the infrared receiver between the conveying track 4 and the transfer track 3 to wait, and the stacker 2 starts to move. The three steps are carried out simultaneously. When the shuttle 5 on the transfer track 3 moves to the side of the infrared receiver, the infrared receiver controls the corresponding shuttle 5 to stop through the central system after receiving the infrared signals from the shuttle 5 on the conveying track 4 or the infrared transmitter on the transfer track 3 respectively. After both stop, the shuttle 5 on the conveying track 4 can accurately transfer the goods to the shuttle 5 on the transfer track 3. After the first transfer of goods is completed, the shuttle 5 continues to move on the transfer track 3 until it moves to the side of the stacker 2. After the infrared receiver on the stacker 2 receives the infrared signal from the infrared transmitter on the shuttle 5, the central system controls the shuttle 5 to stop, and the shuttle 5 on the transfer track 3 transfers the goods to the stacker 2.

[0040] As described above, the present invention provides an intelligent and efficient warehousing system, in which a shuttle 5 with a moving speed faster than that of the stacker 2 works on the transfer track 3 below the shelf 1. Since the stacker 2 with a slower moving speed receives the instruction first and has reached the corresponding shelf 1, the shuttle 5 on the conveying track 4 transfers the goods to the shuttle 5 on the transfer track 3, and then transfers them to the stacker 2, so that the goods are transferred faster, avoiding the efficiency affected by the slow moving speed of the stacker 2 when loaded, and extending the service life of the stacker 2.

[0041] In addition, since the shuttle 5 travels in a single direction, the more shuttles 5 there are on the transfer track 3 and the transport track, the higher the efficiency. The number of shuttles 5 can be selected according to demand, and a spare track is set on one side of the transfer track 3 and the transport track. The main track can still operate after being damaged and will not affect the transportation work of the storage system. The bottom of the U-shaped support frame 11 is embedded in the ground at a different distance according to the storage requirements of the storage system. The higher the height, the more the U-shaped support frame 11 is buried underground.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
