Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent warehousing, and in particular relates to a high-precision transport vehicle for an intelligent warehousing system. Background Art

[0002] Smart warehousing system refers to an intelligent, networked and unmanned warehouse cargo in and out management system. The hardware mainly includes smart transport vehicles, shelves and warehouse in and out record ports. The software mainly includes a cargo management system that can run automatically, monitor in real time and temporarily dispatch.

[0003] The structure of the existing transport vehicle used in the intelligent warehousing system mainly includes a vehicle body, a wireless sensing structure under the vehicle, and a cargo fixing structure on the vehicle. The wireless sensing structure under the vehicle is mainly used to determine the running track of the transport vehicle, while the cargo fixing structure ensures that a row of cargo boxes are vertically aligned and stacked, so that the cargo boxes are not easy to fall during transportation.

[0004] However, the existing cargo fixing structure for transport vehicles only includes a few fixed columns, so it only controls the left and right deviations between the vertically stacked cargo boxes within a relatively large range, so the ability of the cargo boxes to prevent falling is not strong. Therefore, the market is in urgent need of a new type of cargo fixing structure for transport vehicles with higher precision, which can make a row of cargo boxes more accurately aligned vertically and less likely to fall.

[0005] The Chinese utility model patent with patent announcement number CN211544941U and announcement date 2020.09.22 discloses an IGV-guided transport vehicle for a garbage collection station, including a loading and unloading base plate, the bottom of which is connected to a transport vehicle chassis, a pair of running wheels are arranged at the front and rear of the transport vehicle chassis, and the running wheels are driven by a drive motor; a vehicle box fence is arranged around the loading and unloading base plate, a load-bearing net is arranged at the bottom of the loading and unloading base plate, a weighing sensor and a gyroscope are arranged in the load-bearing net, and vehicle box guide docking grooves are also arranged on both sides of the loading and unloading base plate; an acceleration sensor, a magnetic induction sensor, and an ultrasonic sensor are also arranged at the front end of the loading and unloading base plate; an electrical control cabinet is also arranged on the side of the loading and unloading base plate, and an RFID antenna is extended from the top of the electrical control cabinet.

[0006] However, the transport vehicle in this utility model patent has the problem that the cargo fixing effect is poor and the cargo is relatively easy to fall off. Summary of the invention

[0007] The purpose of the present invention is to provide a high-precision transport vehicle for an intelligent warehousing system, which can achieve the effect of stability and non-dropping of cargo boxes during transportation by arranging L-shaped baffles, movable T-shaped plate units and rotating guide plate units on the vehicle body panels. The present invention has the advantages of reasonable and effective active locking structure of cargo boxes, vertical alignment and stacking of cargo boxes of different sizes within a certain range, and non-dropping, compactness and high precision of the locking structure, simple and quick locking and unlocking of cargo boxes, and good overall user experience in the intelligent warehousing system.

[0026] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0027] Example: As attached Figure 1 , 2 , 3, 4, 5, 6 and attached Figure 7 As shown, a high-precision transport vehicle for an intelligent warehousing system includes a body plate 1, and L-shaped baffles 2 arranged on the upper surface of the body plate 1 and respectively located at four end corners and used to limit and fix two rows of cargo boxes 11. It is characterized in that it also includes an active T-shaped plate unit 3 arranged on the body plate 1 and used to push the cargo boxes 11 toward the two pairs of L-shaped baffles 2, and a rotating guide plate unit 4 arranged on the L-shaped baffles 2 and used to limit and fix the cargo boxes 11 whose box width is smaller than the limiting width of the paired L-shaped baffles 2 by rotating open and approaching each other to reduce the effective limiting width.

[0028] In the prior art, the two pairs of L-shaped baffles 2 at both ends of the long side of the vehicle body panel 1 are used to limit, fix, and align a row of cargo boxes 11. However, the following problems are encountered: first, when the cargo box 11 is placed on the vehicle body panel 1, it needs to be pushed toward the inner side of the two L-shaped baffles 2, which is a laborious process. Second, the distance between the relative inner sides of the two L-shaped baffles 2 is the maximum allowable width of the cargo box 11. When the distance is less than this width by more than 5 cm, the alignment between the upper and lower cargo boxes is insufficient, and a row of cargo boxes staggered to the left and right is prone to falling off. Therefore, the prior art cannot engage and align cargo boxes that are much smaller than the preset width.

[0029] Therefore, in this embodiment, the movable T-plate unit 3 is automatically powered to push the cargo box 11 toward the pair of L-shaped baffles 2, and the rotating guide plate unit 4 is used to open towards each other, so that the actual effective width of the pair of L-shaped baffles 2 can be reduced to the width of aligning with the small-sized cargo box. For example, the width between the relative inner sides of the L-shaped baffle 2 is 80 cm, and the minimum allowable cargo box width is 75 cm. When the cargo box width is less than 75 cm, for example 60 cm, the rotating guide plate unit 4 must be opened so that the minimum distance between the two rotating guide plate units 4 is 62 cm. In this way, cargo boxes with a width of 60 cm can be vertically aligned and stacked, and there will be no problem of large left-right deviations between each cargo box.

[0030] The movable T-shaped plate unit 3 includes an outer limiting plate 301 disposed on the upper surface of the vehicle body plate 1, a pushing plate 302 disposed on the inner side of the outer limiting plate 301 and used to push the cargo box 11, a rack 303 disposed on the lower surface of the outer limiting plate 301, a sliding slot 304 disposed on the upper surface of the vehicle body plate 1 and used to accommodate the rack 303, and a driving motor 305 disposed on the lower surface of the vehicle body plate 1 and passing upward through the sliding slot 304 and engaging with the rack 303. The movable T-shaped plate unit 3 also includes an inverted U-shaped plate 306 disposed on the lower surface of the pushing plate 302, a second slot 307 disposed on the upper surface of the vehicle body plate 1 and used to accommodate the inverted U-shaped plate 306, and a rectangular plate 308 disposed in the second slot 307 and used to limit and fix the inverted U-shaped plate 306. The movable T-shaped plate unit 3 also includes an L-shaped plate 309 arranged on the lower surface of the vehicle body plate 1 and used to install the drive motor 305, a gear 310 arranged on the drive motor 305, and a circular hole 311 arranged on the bottom surface of the sliding slot 304 and used to pass through and install the drive motor 305.

[0031] In this embodiment, the two pairs of L-shaped baffles 2 correspond to a pair of movable T-shaped plate units 3. When the movable T-shaped plate units 3 slide to the left or right, a row of cargo boxes can be vertically aligned and stacked in the two pairs of L-shaped baffles 2, ensuring that the cargo boxes are vertically aligned and not easy to fall.

[0032] Among them, the back side of the rack 303 is attached to the inner side of the sliding groove 304, ensuring that the rack 303 and the entire outer limiting plate 301 and the push plate 302 can slide linearly stably, and the drive motor 305 is a stepping motor that can accurately select forward or reverse rotation.

[0033] In addition, the inverted U-shaped plate 306 is engaged with the rectangular plate 308 to further ensure that the outer limiting plate 301 and the push plate 302 as a whole only slide linearly without any deflection or jamming problem, and the gear 310 is the direct driving part of the drive motor 305 to drive the rack 303, and an independent power supply for powering the drive motor 305 is provided on the lower surface of the vehicle body plate 1.

[0034] The rotating guide plate unit 4 includes a rectangular groove 401 arranged on the inner side of the side limit plate 2a of the L-shaped baffle 2, a rotating plate 402 arranged in the rectangular groove 401 and opened by rotating outward to reduce the actual limit width between the two side limit plates 2a, a mounting shaft 403 arranged on the lower surface of the rotating plate 402 and away from the end blocking plate 2b, a third slot 404 arranged on the upper surface of the vehicle body plate 1 and used to insert the mounting shaft 403 downward, a second gear 405 arranged on the mounting shaft 403 and located in the third slot 404, a sliding plate 406 arranged on the third slot 404, and a tooth 407 arranged on the sliding plate 406 and meshing with the second gear 405. The rotating guide plate unit 4 further includes a rectangular channel 408 disposed on the third slot 404 and connected to the sliding slot 304 and used for inserting and installing the sliding plate 406. The rotating plate 402 rotates outward and opens when the sliding plate 406 is pushed by the rack 303. The rotating guide plate unit 4 further includes a limiting groove 409 disposed on the third slot 404 and away from one end of the rectangular channel 408 and used for limiting and installing the sliding plate 406, and an auxiliary shaft 410 disposed on the upper surface of the rotating plate 402 and vertically aligned with the installation shaft 403 and used for inserting into the top surface of the rectangular slot 401.

[0035] In this embodiment, there are four rotating guide plate units 4, which are arranged in pairs and are used to guide cargo boxes whose alignment width is less than a preset value toward the middle. The preset value is the distance between the inner surfaces of the two side limit plates 2a.

[0036] Among them, after the rotating plate 402 is rotated and opened, the distance between the closest edges of the two rotating plates 402 can ensure that the width of the smaller cargo box is 2-5 cm larger. In this way, the smaller cargo box can also be vertically aligned with small left and right deviations, and a row of cargo boxes will not be crooked and will not easily fall off.

[0037] In addition, the sliding plate 406 cooperates with the teeth 407 to input power for driving the rotating plate 402 to rotate and open. A hole for inserting the mounting shaft 403 is provided on the inner bottom surface of the rectangular groove 401, and a groove for inserting the auxiliary shaft 410 is provided on the inner top surface, so that the rotating plate 402 can be smoothly rotated to open and rotated back.

[0038] Finally, the force for the rotating plate 402 to rotate open comes from the rack 303 pushing the sliding plate 406, while the force for rotating and retracting requires manual pushing of the rotating plate 402 inward. The two rotating plates 402 need to be opened to the required width before stacking smaller cargo boxes, and when the two rotating plates 402 are rotated and opened to be perpendicular to the side limit plates 2a, the distance between the sides of the two rotating plates 402 is the minimum allowable size of the cargo box width. Cargo boxes smaller than this are not suitable for the transport vehicle in this embodiment.

[0039] The rotating deflector unit 4 also includes an internal threaded hole 411 disposed on the rotating plate 402 and at a position away from the installation shaft 403, and a threaded column 412 disposed on the internal threaded hole 411 and used to fix the threaded column 412 that has been rotated open by rubbing against the upper surface of the vehicle body panel 1 after downward rotation. The rotating deflector unit 4 also includes an adjustment slot 413 disposed on the upper surface of the rotating plate 402 and located above the internal threaded hole 411 and used to expose the upper end of the threaded column 412, and a friction elastic block 414 disposed on the lower end surface of the threaded column 412. The rotating deflector unit 4 also includes two elastic sheets 415 disposed on the inner side surface of the adjustment slot 413 and the vertical side surface of the rotating plate 402 and used to hold the rotating plate 402 when it is rotated and retracted.

[0040] In this embodiment, after the rotating plate 402 is rotated and opened to the desired angle, the rack 303 is to be retracted to drive the movable T-plate unit 3. Therefore, the rotating plate 402 requires a post-rotation fixing structure to prevent the rotating plate 402 from being accidentally recovered into the rectangular groove 401. The fixing structure is that the threaded column 412 rotates downward until the friction force between the friction elastic block 414 and the upper surface of the vehicle body panel 1 is sufficient and appropriate.

[0041] When the rotating plate 402 is idle in the rectangular groove 401, the threaded column 412 is at a relatively high position in the internal threaded hole 411, ensuring that the rotating plate 402 can be completely "retracted" into the rectangular groove 401, and the adjustment slot 413 is used to insert fingers to pinch and rotate the threaded column 412, while the elastic sheet 415 is used to comfortably pinch the rotating plate 402 and push the rotating plate 402 back into the rectangular groove 401, which means that the transportation of this batch of cargo boxes on the transport vehicle has been completed.

[0042] Finally, the L-shaped baffle 2, the outer limiting plate 301 and the push plate 302 in this embodiment are all of the same height, at least equal to the total height of the preset number of boxes, to ensure that both rows of boxes are not easy to fall, and the elastic sheet 415 and the friction elastic block 414 are both existing high-strength rubber.

[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
