Description

Technical Field

[0001] This invention belongs to the field of shuttle technology, and particularly relates to a compact, multifunctional intelligent shuttle robot. Background Technology

[0002] Shuttles in warehousing and logistics equipment mainly come in two forms: shuttle-type inbound / outbound systems and shuttle-type storage systems. These are trolleys that run on fixed tracks in a reciprocating or looping manner, transporting goods to designated locations or connecting equipment. They are equipped with intelligent sensing systems that can automatically memorize the origin position and automatic deceleration systems.

[0003] Currently, different types of racking systems are used to transport pallets and moving bins, so only two different types of shuttles can be used. This makes the shuttles less versatile, and deploying a large number of shuttles will greatly increase the cost of the warehousing system. In addition, the lifting and drive modules used by the shuttles are separate, which requires multiple different drive systems, making the structural design complex and the vehicle body occupying a large space. Summary of the Invention

[0004] The purpose of this invention is to address the problems of shuttles with different structures used for transporting pallets and moving containers, where the lifting and drive modules of the shuttles are designed separately, resulting in poor shuttle versatility, complex structural design, and large space occupation of the shuttle body. Therefore, this invention proposes a compact, multi-functional intelligent shuttle robot.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a compact multi-functional intelligent shuttle robot, which includes a body, multiple first drive wheels, multiple second drive wheels, multiple sets of lifting turbine mechanisms, telescopic arm mechanisms, and two sets of drive mechanisms.

[0006] Multiple sets of the lifting turbine mechanisms are respectively located at the four corners of the vehicle body. The multiple sets of the lifting turbine mechanisms are symmetrically distributed, and two symmetrical sets of the lifting turbine mechanisms are connected by a first shaft.

[0007] Multiple first drive wheels are symmetrically distributed on opposite sides of the vehicle body. Two symmetrical first drive wheels are connected by a second axle. The second axle passes through two sets of lifting turbine mechanisms, which drive the second axle to rise and fall.

[0008] Multiple second drive wheels are symmetrically distributed on opposite sides of the vehicle body. The axis of the second drive wheel is perpendicular to the axis of the first drive wheel. Two second drive wheels located on the same side of the vehicle body are connected by a third axle. The ends of the second drive wheels and the third axle are connected by a steering box, which is mounted on the vehicle body.

[0009] Two sets of drive mechanisms are located inside the vehicle body. The drive mechanisms connect the first axle, the second axle, and the third axle, and drive the first axle to rotate, drive the second axle to rotate, and drive the third axle to rotate.

[0010] The telescopic arm mechanism is mounted on the vehicle body and is located between the two sets of drive mechanisms.

[0011] As a further description of the above technical solution:

[0012] The first shaft, the second shaft, and the third shaft are parallel to each other.

[0013] As a further description of the above technical solution:

[0014] The drive mechanism includes a first motor and two sets of electronically controlled clutches. The first motor is fixedly mounted on the vehicle body, and the two sets of electronically controlled clutches are mounted on the first motor. One set of electronically controlled clutches drives the first shaft to rotate via a synchronous belt, and the other set of electronically controlled clutches drives the second shaft to rotate and the third shaft to rotate via a synchronous belt.

[0015] As a further description of the above technical solution:

[0016] The lifting turbine mechanism includes a housing, a worm gear, a turbine body, a solenoid, a lead screw, and a lifting plate. The housing is fixedly mounted on the vehicle body. The worm gear is hinged to the housing and connected to the end of the first shaft. The solenoid is hinged to the housing. The turbine body is connected to the solenoid and meshes with the worm gear. The lifting plate is slidably disposed in the housing in a vertical direction. The lead screw is fixedly connected to the lifting plate and screwed to the solenoid. The second shaft passes through the lifting plate and is hinged to the lifting plate.

[0017] As a further description of the above technical solution:

[0018] The electronically controlled clutch is connected to the third shaft via a timing belt. A transition shaft is hinged to the vehicle body. The transition shaft is connected to the second shaft and the third shaft via timing belts. A tensioning mechanism is provided on the vehicle body. The tensioning mechanism abuts against the timing belt connecting the second shaft and the transition shaft.

[0019] As a further description of the above technical solution:

[0020] The tensioning mechanism includes a bracket, a tension wheel, and a torsion spring. The bracket is hinged to the vehicle body and is located above the transition shaft. The torsion spring is connected to the bracket and abuts against the vehicle body. The tension wheel is hinged to the end of the bracket and abuts against the timing belt connecting the second shaft and the transition shaft.

[0021] As a further description of the above technical solution:

[0022] The telescopic boom mechanism includes a second motor and a cargo-retrieving arm body. The second motor is fixedly installed inside the vehicle body, and the cargo-retrieving arm body is slidably mounted on the vehicle body. The second motor is equipped with a gear, and the cargo-retrieving arm body is equipped with a rack, with the gear meshing with the rack.

[0023] As a further description of the above technical solution:

[0024] The top surface of the pickup arm body coincides with the top surface of the vehicle body.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In this invention, the first and second drive wheels are driven to rotate by a drive mechanism, which in turn drives the lifting turbine mechanism to rise and fall, giving the vehicle body the functions of four-way movement and lifting, thus meeting the needs of transporting material boxes. At the same time, a telescopic arm mechanism is provided on the vehicle body. Under the action of the second motor, the picking arm body moves along a straight line and extends from one side of the vehicle body. The picking arm body can be inserted into the pallet, thereby meeting the needs of transporting pallets. This makes the shuttle car applicable to different racking systems and highly versatile.

[0027] 2. In this invention, two sets of electronically controlled clutches are connected to the first motor. One set of electronically controlled clutches is connected to the first shaft and drives the first shaft to rotate. The rotation of the first shaft drives the lifting turbine mechanism, which in turn drives the second shaft to rise and fall, thereby causing the first drive wheel to rise and fall, so that the first drive wheel touches the ground and the entire vehicle body is lifted. The other set of electronically controlled clutches drives the second and third shafts to rotate, thus driving the first and second drive wheels to rotate. Combined with the rising and falling of the first drive wheel, the first and second drive wheels alternately touch the ground, thus causing the vehicle body to move in four directions. The lifting and driving modules are cleverly combined in the design, requiring only a single drive source, which greatly saves the space occupied by the transmission structure inside the vehicle body and facilitates a simplified and compact design of the overall vehicle body structure.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1-16 The present invention provides a technical solution: a compact multi-functional intelligent shuttle robot, comprising a body 1, four first drive wheels 2, four second drive wheels 3, four sets of lifting turbine mechanisms 4, a telescopic arm mechanism 5, and two sets of drive mechanisms 6;

[0048] The four sets of lifting turbine mechanisms 4 are respectively located at the four corners of the vehicle body 1. The four sets of lifting turbine mechanisms 4 are symmetrically distributed in pairs, and the two sets of lifting turbine mechanisms 4 that are symmetrical to each other are connected by the first shaft 7.

[0049] Four first drive wheels 2 are symmetrically distributed in pairs on opposite sides of the vehicle body 1. Two symmetrical first drive wheels 2 are connected by a second axle 8. The second axle 8 passes through two sets of lifting turbine mechanisms 4, and the lifting turbine mechanism 4 drives the second axle 8 to rise and fall.

[0050] Four second drive wheels 3 are symmetrically distributed in pairs on opposite sides of the vehicle body 1. The axis of the second drive wheel 3 is perpendicular to the axis of the first drive wheel 2. Two second drive wheels 3 located on the same side of the vehicle body 1 are connected by a third axle 9. The ends of the second drive wheels 3 and the third axle 9 are connected by a steering box 10, which is mounted on the vehicle body 1.

[0051] Two sets of drive mechanisms 6 are provided inside the vehicle body 1. The drive mechanism 6 connects the first shaft 7, the second shaft 8 and the third shaft 9, and the drive mechanism 6 drives the first shaft 7 to rotate, drives the second shaft 8 to rotate and drives the third shaft 9 to rotate.

[0052] The telescopic arm mechanism 5 is mounted on the vehicle body 1 and is located between the two sets of drive mechanisms 6;

[0053] The first shaft 7, the second shaft 8, and the third shaft 9 are parallel to each other, which facilitates stable transmission.

[0054] The drive mechanism 6 includes a first motor 61 and two sets of electronically controlled clutches 62. The first motor 61 is fixedly mounted on the vehicle body 1, and the two sets of electronically controlled clutches 62 are mounted on the first motor 61. One set of electronically controlled clutches 62 drives the first shaft 7 to rotate via a synchronous belt, and the other set of electronically controlled clutches 62 drives the second shaft 8 and the third shaft 9 to rotate via a synchronous belt. Corresponding pulleys are fixedly mounted on the electronically controlled clutches 62, the first shaft 7, the second shaft 8, and the third shaft 9, and the pulleys are used to connect with the synchronous belt. When the first motor 61 is always running, when one set of electronically controlled clutches 62 is closed and the other set of electronically controlled clutches 62 is open, the second drive wheel 3 is in contact with the ground, and the second shaft 8 and the third shaft 9 are rotating. Both the first drive wheel 2 and the second drive wheel 3 are rotating. At this time, the body 1 moves under the driving action of the second drive wheel 3. When both electronically controlled clutches 62 are in the open state, the first shaft 7, the second shaft 8 and the third shaft 9 are all rotating. The lifting turbine mechanism 4 drives the second shaft 8 to descend under the driving action of the first shaft 7. The first drive wheel 2 descends with the second shaft 8 and replaces the second drive wheel 3 to contact the ground. Both the first drive wheel 2 and the second drive wheel 3 are rotating. At this time, the body 1 moves under the driving action of the first drive wheel 2, thus realizing four-way movement. At the same time, the overall height of the body 1 is also raised. The transmission structure is cleverly designed, which greatly saves the space occupied by the transmission structure inside the body 1, making it easy to simplify and compact the overall structure of the body 1.

[0055] The lifting turbine mechanism 4 includes a housing 41, a worm gear 42, a turbine body 43, a solenoid 44, a lead screw 45, and a lifting plate 46. The housing 41 is fixedly mounted on the vehicle body 1. The worm gear 42 is hinged inside the housing 41 and connected to the end of the first shaft 7. The solenoid 44 is hinged to the housing 41. The turbine body 43 is connected to the solenoid 44 and meshes with the worm gear 42. The lifting plate 46 is slidably disposed within the housing 41 in a vertical direction. The lead screw 45 is fixedly connected to the lifting plate 46 and screwed to the solenoid 44. The second shaft 8 passes through the lifting plate 46, and the second... The shaft 8 is hinged to the lifting plate 46. When the first shaft 7 rotates, it drives the worm gear 42 to rotate. The rotation of the worm gear 42 drives the turbine body 43 to rotate. The rotation of the turbine body 43 drives the solenoid 44 to rotate. Since the solenoid 44 does not move during rotation, the lead screw 45 screwed to the solenoid 44 moves. The degree of freedom of the lead screw 45 is released together with the lifting plate 46 connected to it, thereby driving the lifting plate 46 to slide vertically along the inside of the housing 41. The lifting of the lifting plate 46 drives the lifting of the second shaft 8. The transmission method combining the turbine and the solenoid 44 results in high transmission efficiency and smooth lifting process. It avoids the noise generated when using hydraulic and chain transmissions and reduces manufacturing costs.

[0056] The electronically controlled clutch 62 is connected to the third shaft 9 via a synchronous belt. A transition shaft 11 is hinged to the vehicle body 1, and the transition shaft 11 is connected to the second shaft 8 and the third shaft 9 via synchronous belts. A tensioning mechanism 12 is provided on the vehicle body 1, and the tensioning mechanism 12 abuts against the synchronous belt connecting the second shaft 8 and the transition shaft 11. The tensioning mechanism 12 includes a bracket 121, a tension wheel 122, and a torsion spring 123. The bracket 121 is hinged to the vehicle body 1 and is located above the transition shaft 11. The torsion spring 123 is connected to the bracket 121 and abuts against the vehicle body 1. The tension wheel 122 is hinged to the end of the bracket 121 and abuts against the synchronous belt connecting the second shaft 8 and the transition shaft 9. The timing belt of the transition shaft 11 has corresponding pulleys fixedly installed on it. The pulleys are used to connect with the timing belt. The transition shaft 11 connects the second shaft 8 and the third shaft 9 respectively. When the position of the second shaft 8 changes, the position between the third shaft 9 and the transition shaft 11 is not fixed, and the transmission is in a statically stable state. The second shaft 8 and the transition shaft 11 are in a dynamic connection. Therefore, the tension of the timing belt connecting the second shaft 8 and the transition shaft 11 is constantly changing. The torsion spring 123 is used to adjust the bracket 121 by rotating it along the vehicle body 1. The tension wheel 122 at the end of the bracket 121 abuts against the timing belt, so that the timing belt connecting the second shaft 8 and the transition shaft 11 is always in a taut state. This makes the transmission in a dynamically stable state, with good transmission effect and high transmission efficiency.

[0057] The telescopic arm mechanism 5 includes a second motor 51 and a picking arm body 52. ​​The second motor 51 is fixedly installed inside the vehicle body 1, and the picking arm body 52 is slidably mounted on the vehicle body 1. The second motor 51 is provided with a gear 13, and the picking arm body 52 is provided with a rack 14. The gear 13 meshes with the rack 14. The rotation of the second motor 51 drives the gear 13 to rotate, and the gear 13 drives the rack 14 to move in a straight line. Therefore, the picking arm body 52 moves in a straight line and extends from one side of the vehicle body 1. The picking arm body 52 is inserted into the pallet, or the reciprocating motion of the picking arm body 52 drags the material box to the center of the vehicle body 1, which satisfies the work of simultaneously handling pallets and material boxes. It has strong functionality and versatility.

[0058] The top surface of the picking arm body 52 coincides with the top surface of the vehicle body 1, ensuring that the top surface of the vehicle body 1 is flat, thereby ensuring that the goods are transported smoothly.

[0059] Working principle: First, when the vehicle body 1 needs to move in one direction, the first motor 61 is always running. One set of electronically controlled clutches 62 is closed, and the other set is open. (A controller can be installed inside the vehicle body 1. The controller is electrically connected to the two electronically controlled clutches 62 and controls the switching of the electronically controlled clutches 62.) The second drive wheel 3 is in contact with the ground. The electronically controlled clutches 62 drive the third shaft 9 to rotate via a synchronous belt. The third shaft 9 drives the transition shaft 11 to rotate via a synchronous belt. The transition shaft 11 drives the second shaft 8 to rotate via a synchronous belt. The tensioning mechanism 12 continuously presses against the synchronous belt connecting the second shaft 8 and the transition shaft 11. The rotation of the second shaft 8 drives the first drive wheel connected to it. 2. The third axle 9 rotates, driving the steering box 10 to rotate (the steering box 10 is a right-angle steering box used to change the transmission direction). Under the direction-changing action of the steering box 10, the second drive wheel 3 starts to rotate. At this time, the vehicle body 1 moves under the driving action of the second drive wheel 3. Secondly, when the vehicle body 1 needs to be lifted or move in another direction, the first motor 61 is always running, both sets of electronically controlled clutches 62 are in the open state, the second drive wheel 3 is in contact with the ground, the electronically controlled clutches 62 drive the third axle 9 to rotate through the synchronous belt, the third axle 9 drives the transition shaft 11 to rotate through the synchronous belt, the transition shaft 11 drives the second axle 8 to rotate through the synchronous belt, and the tensioning mechanism 12 always abuts against the connection between the second axle 8 and the transition shaft 11. The synchronous belt drives the second shaft 8 to rotate, which in turn drives the first drive wheel 2 connected to it to rotate. The third shaft 9 rotates, which in turn drives the steering box 10 to rotate. Under the direction-changing action of the steering box 10, the second drive wheel 3 begins to rotate. At the same time, the electric clutch drives the first shaft 7 to rotate via the synchronous belt. When the first shaft 7 rotates, it drives the worm gear 42 to rotate. The worm gear 42 rotates and drives the turbine body 43 to rotate. The turbine body 43 rotates and drives the solenoid tube 44 to rotate. Since the solenoid tube 44 does not move during rotation, the lead screw 45 screwed to the solenoid tube 44 moves. The degree of freedom of the lead screw 45 is released together with the lifting plate 46 connected to it, thereby driving the lifting plate 46 to slide vertically along the inside of the housing 41. The lifting of the lifting plate 46 drives the second shaft 8 to rotate. As the vehicle body 1 descends, the first drive wheel 2 descends along with the second axle 8. At this time, due to the change in the position of the second axle 8, the tension of the synchronous belt connecting the second axle 8 and the transition shaft 11 continuously changes. The torsion spring 123 acts on the bracket 121, which rotates and adjusts along the vehicle body 1, causing the tension wheel 122 at the end of the bracket 121 to abut against the synchronous belt. This ensures that the synchronous belt connecting the second axle 8 and the transition shaft 11 remains taut. The first drive wheel 2 replaces the second drive wheel 3 in contact with the ground, and the vehicle body 1 moves under the action of the first drive wheel 2, raising the overall height of the vehicle body 1. Then, when the vehicle body 1 needs to transport a pallet, the second motor 51 rotates, driving the gear 13 to rotate. The gear 13 drives the rack 14 to move in a straight line.Therefore, the picking arm body 52 moves in a straight line and extends from one side of the vehicle body 1. The picking arm body 52 inserts into the pallet. Finally, when the vehicle body 1 needs to transport regular packages, the packages can be placed directly on top of the vehicle body 1. Additionally, a servo driver can be installed inside the vehicle body 1. The servo driver connects to the first motor 61 and the second motor 51, thereby controlling the forward and reverse rotation of the first motor 61 and the second motor 51. Thus, the rotation direction of the first drive wheel 2, the rotation direction of the second drive wheel 3, the rising and falling of the lifting plate 46, and the movement direction of the picking arm body 52 can all be controlled accordingly.
