Description

Technical Field

[0001] The present invention relates to the technical field of transport equipment, and in particular to a multi-directional shuttle transport device. Background Art

[0002] As a common equipment in the field of logistics and warehousing, shuttle cars are mainly small cars that move back and forth along tracks to achieve the entry and exit of goods. At present, the cargo handling equipment commonly used in stereoscopic warehouses on the market is divided into mother-child cars and four-way shuttle cars. However, the existing mother-child cars have two independently moving small cars that are combined with each other to achieve movement in the X and Y axis directions on the plane, which has problems such as high cost and control difficulty. In addition, the four-way shuttle cars in the current related technologies all use a vertically arranged drive wheel system plus a reversing component to achieve steering movement. They have a complex structure and many parts, which makes the whole machine bulky, difficult to assemble, and occupies a large space.

[0003] Therefore, how to design a multi-directional shuttle transport device with simple structure and low cost has become a problem that needs to be solved urgently. Summary of the invention

[0004] The present invention aims to at least solve the problems of a four-way shuttle vehicle having a complex structure, numerous parts and components, and high cost.

[0005] To this end, a first aspect of the present invention provides a multi-directional shuttle transport device.

[0006] In view of this, the first aspect of the present invention proposes a multi-directional shuttle transport device, comprising: a walking mechanism; a rotating main shaft, rotatably installed on the walking mechanism, and the rotating main shaft can drive the walking mechanism to move when it rotates; a loading platform, rotatably installed on the rotating main shaft, and located above the walking mechanism; a driving assembly, connected to the rotating main shaft and the walking mechanism, used to drive the rotating main shaft to rotate to drive the walking mechanism to move, and used to drive the walking mechanism to rotate to adjust the walking direction of the walking mechanism.

[0007] The multi-directional shuttle transport device provided by the present invention comprises a traveling mechanism, a rotating spindle, a loading platform and a driving assembly. The driving assembly can drive the rotating spindle to rotate, thereby driving the traveling mechanism to move. The driving assembly can also drive the traveling mechanism to rotate, thereby changing the traveling direction of the traveling mechanism. Specifically, the rotating spindle is rotatably mounted on the traveling mechanism, and the rotating spindle can drive the traveling mechanism to move when rotating. For example, the rotating spindle and the traveling mechanism can be rotatably mounted by the cooperation of a plurality of bevel gears, so that the traveling mechanism can be driven to move by the rotation of the rotating spindle. Of course, the rotatable installation can also be performed in other ways. The loading platform is arranged above the traveling mechanism, and can carry the goods to be transported to realize the transportation of the goods. In addition, in order to ensure the stability of the loading platform, the loading platform can be rotatably mounted on the rotating spindle, so that when the rotating spindle rotates to drive the traveling mechanism to move, it can be ensured that the loading platform does not rotate with it, thereby ensuring the stability of the loading platform and ensuring that the goods do not fall. When driving the rotating spindle to rotate or driving the traveling mechanism to rotate, it can be driven by the driving assembly to ensure that there is enough power to drive. It is understandable that the multi-directional shuttle transport device provided by the present application can realize the movement and steering of the entire device only by the cooperation of the rotating main shaft and the walking mechanism, so the structure is simple and reliable, the manufacturing cost is low, and the speed of switching direction is fast, so the transportation efficiency can be improved. Moreover, when the multi-directional shuttle transport device of the present application is enlarged or reduced according to actual needs, the device of the present application will not increase the manufacturing cost much.

[0008] The multi-directional shuttle transport device provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, the multi-directional shuttle transport device can move along the track, and the multi-directional shuttle transport device also includes: a driving gear, which is arranged on the rotating main shaft; a rack, which is installed on the inner wall of the track, and when the rotating main shaft rotates, the driving gear can cooperate with the rack to drive the walking mechanism to move along the track.

[0010] In these embodiments, the multi-directional shuttle transport device can be configured to move along a track. Specifically, a driving gear can be provided on the rotating main shaft, and a rack can be provided on the inner wall of the track, so that when the driving gear rotates and cooperates with the rack, the multi-directional shuttle transport device can be moved.

It can be understood that, since the present application can drive the running mechanism to rotate through the driving assembly, there is no need to set up other additional driving mechanisms to drive the transfer track to rotate, and it is only necessary to use the rotation of the running mechanism to drive the transfer track to rotate, which further saves costs.

It can be understood that the solution of arranging a chain around the transmission disc has a lower cost and can further save costs.

[0027] In some embodiments, optionally, the second transmission assembly includes: a gear plate fixedly mounted on the walking mechanism for cooperating with the driving assembly.

The driving assembly 4 can drive the rotating spindle 2 to rotate, thereby driving the traveling mechanism 1 to move. The driving assembly 4 can also drive the traveling mechanism 1 to rotate, thereby changing the traveling direction of the traveling mechanism 1. Specifically, the rotating spindle 2 is rotatably mounted on the traveling mechanism 1, and the rotating spindle 2 can drive the traveling mechanism 1 to move when rotating. For example, the rotating spindle 2 and the traveling mechanism 1 can be rotatably mounted through the cooperation of a plurality of bevel gears 7, so that the traveling mechanism 1 can be driven to move by the rotation of the rotating spindle 2. Of course, the rotating installation can also be carried out in other ways. The loading platform 3 is arranged above the traveling mechanism 1, and can carry the goods to be transported to realize the transportation of the goods. In addition, in order to ensure the stability of the loading platform 3, the loading platform 3 can be rotatably mounted on the rotating spindle 2, so that when the rotating spindle 2 rotates to drive the traveling mechanism 1 to move, it can be ensured that the loading platform 3 does not rotate with it, thereby ensuring the stability of the loading platform 3 and ensuring that the goods do not fall. When driving the rotating main shaft 2 to rotate or driving the traveling mechanism 1 to rotate, it can be driven by the driving component 4 to ensure that there is sufficient power to drive. It can be understood that the multi-directional shuttle transport device provided by the present application can achieve the movement and steering of the entire device only by the cooperation of the rotating main shaft 2 and the traveling mechanism 1. Therefore, the structure is simple and reliable, the manufacturing cost is low, and the speed of switching direction is fast, so the transportation efficiency can be improved.

[0100] In some embodiments, optionally, the first rotational bearing 23 is a first cross roller bearing 231 .

[0101] In these embodiments, when the first rotating bearing 23 is a first cross roller bearing 231, the first cross roller bearing 231 can be connected and fixed to the loading platform 3 by means of bolts 8. Specifically, the first cross roller bearing 231 can be arranged below the loading platform 3, and then the bolts 8 can be passed through the loading platform 3 from above the loading platform 3 to cooperate with the outer ring of the first cross roller bearing 231, so as to achieve fixed installation of the two.

[0102] In some embodiments, optionally, the multi-directional shuttle transport device further includes: a second rotating bearing 24 fixedly mounted on the rotating main shaft 2 ; the walking mechanism 1 fixedly mounted on the second rotating bearing 24 , and the walking mechanism 1 and the rotating main shaft 2 rotate through the second rotating bearing 24 .

[0103] In these embodiments, the walking mechanism 1 can be rotatably mounted on the rotating main shaft 2 through the second rotating bearing 24. Specifically, the second rotating bearing 24 is fixedly mounted on the rotating main shaft 2, and then the walking mechanism 1 is fixedly mounted on the second rotating bearing 24, so that the walking mechanism 1 and the rotating main shaft 2 can be rotated through the second rotating bearing 24. By setting the second rotating bearing 24 for rotation, the rotation performance can be improved, and then the overall service life of the multi-directional shuttle transport device can be improved.

[0104] In some embodiments, optionally, the second rotation bearing 24 is a second cross roller bearing 241 .

[0105] In these embodiments, when the second rotating bearing 24 is a second cross roller bearing 241 , the second cross roller bearing 241 can be connected and fixed to the traveling mechanism 1 by bolts 8 .

[0106] In some embodiments, optionally, in order to facilitate the axial positioning of the loading platform 3 and the walking mechanism 1 , the rotating main shaft 2 can be set as a stepped shaft.

[0107] In some embodiments, optionally, Figures 11 to 15 As shown, the multi-directional shuttle transport device further includes: a plurality of bevel gears 7, which are respectively mounted on the rotating main shaft 2 and the traveling mechanism 1. The rotating main shaft 2 drives the traveling mechanism 1 to move through the cooperation of the plurality of bevel gears 7.

[0108] In these embodiments, multiple bevel gears 7 can be provided to realize the movement of the rotating main shaft 2 driving the traveling mechanism 1. Specifically, multiple bevel gears 7 can be installed on the rotating main shaft 2 and the traveling mechanism 1 respectively, and the traveling mechanism 1 can be driven to move by the cooperation of multiple bevel gears 7. In this case, it is not necessary to provide a rack 51 on the side wall of the track 5, and it is not necessary to make the multi-directional shuttle transport device move along the track 5, so that the multi-directional shuttle transport device can move in any direction.

[0109] In some embodiments, optionally, Fig.16 As shown, the plurality of bevel gears 7 include a large bevel gear and a small bevel gear. The rotating main shaft 2 rotates to drive the large bevel gear to rotate. The large bevel gear meshes with the small bevel gear to drive the small bevel gear to rotate. Fig.17 As shown, the bevel gear shaft 15 of the small bevel gear is a stepped shaft, and the axial positioning of the small bevel gear is achieved through the keyway and the shaft retaining ring. Therefore, further, the bevel gear 7 rotates, driving the bevel gear shaft 15 to rotate, and then driving the travel wheel 13 to rotate. Since the travel wheel 13 is on the special groove track 5, the axial positioning of the travel wheel 13 along the bevel gear shaft 15 is guaranteed. In addition, the shaft retaining ring on the bevel gear shaft 15 also ensures the axial positioning of the bevel gear 7.

[0110] In some embodiments, optionally, in order to realize the vertical positioning of the bottom running wheel 13, an adjusting bolt 8 is used, which passes through the transmission plate 121 through a threaded hole, and then is connected to the joint bearing 14, with one group arranged on the left and right, and the bevel gear shaft 15 passes through the inner ring of the joint bearing 14, without the need for axial positioning, that is, the meshing distance of the bevel gear 7 can be adjusted by rotating the bolt 8, and the vertical positioning of the running wheel 13 is realized. The working process is: when the small bevel gear rotates, it drives the running wheel 13 to rotate, and the whole machine moves forward or backward. Similarly, the bottom track can only rotate at the intersection, and the rest are fixed tracks. When the trolley is moving, there is no need to balance the torque.

[0111] In some embodiments, optionally, the driving assembly 4 includes: a first driving motor 41, installed on the loading platform 3, for driving the rotating spindle 2 to rotate; a second driving motor 42, installed on the loading platform 3, for driving the walking mechanism 1 to rotate.

[0112] In these embodiments, the driving assembly 4 includes a first driving motor 41 and a second driving motor 42. The first driving motor 41 and the second driving motor 42 are installed on the loading platform 3, and the first driving motor 41 can drive the rotating spindle 2 to rotate, and the second driving motor 42 can drive the walking mechanism 1 to rotate. By setting two driving motors, the power requirements of the multi-directional shuttle transport device can be ensured.

[0113] In some embodiments, optionally, the first drive motor 41 and the second drive motor 42 are symmetrically installed on the loading platform 3 .

[0114] In these embodiments, in order to ensure the balance of the loading platform 3 , the first driving motor 41 and the second driving motor 42 may be symmetrically installed on the loading platform 3 .

[0115] In some embodiments, optionally, the first drive motor 41 is a bidirectional motor and / or the second drive motor 42 is a bidirectional motor.

[0116] In these embodiments, the first drive motor 41 is a bidirectional motor and / or the second drive motor 42 is a bidirectional motor, so that the rotation spindle 2 can be rotated forward and reversely, and the walking mechanism 1 can be moved forward and backward. Of course, the walking mechanism 1 can also be rotated forward and reversely, so as to adjust the walking direction.

[0117] In some embodiments, optionally, in order to further balance the torque of the loading platform 3 during walking and turning so that the loading platform 3 remains stable, a multi-directional shuttle transport device may be used in combination, for example, the loading platforms 3 of two multi-directional shuttle transport devices may be connected together and then used in combination, thereby offsetting the torque of the loading platform 3.

[0118] In some embodiments, optionally, adjusting wheels may be symmetrically arranged on the loading platform 3 so that the adjusting wheels are in contact with the track 5 , thereby balancing the torque of the loading platform 3 during walking and turning.

[0119] In some embodiments, optionally, the multi-directional shuttle transport device is a four-directional shuttle.

[0120] According to an embodiment of the first aspect of the present invention, a multi-directional shuttle transport device is provided, comprising: a top platform, a rotating platform, a drive shaft system, a track 5 (transfer track 6), a rack 51 and a drive gear 21. The top platform, the rotating platform and the drive shaft system are axially fixed and can rotate relatively independently.

[0121] In some embodiments, optionally, the top platform includes a top plate (loading platform 3) and a universal ball wheel (support member 31), wherein the universal ball wheel is fixed on the top plate, and when the top plate is subjected to force, the universal ball wheel can distribute the force evenly, and when the rotating platform rotates, the universal ball wheel will not interfere with it.

[0122] In some embodiments, optionally, the rotating platform includes a turntable (transmission disk 121), a walking wheel 13 system (walking mechanism 1) and a chain plate 124, wherein the walking wheel 13 system is composed of a wheel frame and a directional wheel, the directional wheel moves along the groove of the track 5, and the wheel frame and the chain plate 124 are fixed on the turntable.

[0123] In some embodiments, the drive shaft system optionally includes a plurality of bolts 8, a first cross roller bearing 231, a small pad 25, a sprocket (first transmission assembly 22), a fixing nut 26, a large pad 27, a second cross roller bearing 241 and a rotating main shaft 2. The bolt 8 passes through the top plate and cooperates with the outer ring of the first cross roller bearing 231. Among them, a small pad 25, a sprocket (first transmission assembly 22), a fixing nut 26, a large pad 27, a turntable (transmission disk 121) and a second cross roller bearing 241 are sequentially arranged below the first cross roller bearing 231, and a long bolt is used to pass through in sequence so that the inner ring of the second cross roller bearing 241 cooperates with the inner ring of the first cross roller bearing 231 to fix it. The rotating main shaft 2 is a stepped shaft with threads provided thereon, and the fixing nut 26 is fixed on the rotating main shaft 2 so that the walking wheel 13 is kept fixed in the axial direction. The rotating spindle 2 can rotate freely relative to the top platform. In addition, the second cross roller bearing 241 cooperates with the stepped surface of the rotating spindle 2 for axial fixation. The turntable on the rotating platform is fixed on the outer ring of the second cross roller bearing 241, so that the turntable can rotate independently relative to the rotating spindle 2. By setting two cross roller bearings, the top platform, the rotating platform and the driving shaft system can all rotate relatively independently, and under the action of the fixing nut 26, the three will not move relative to each other in the axial direction.

[0124] In some embodiments, optionally, the drive of the bottom gear rack 51 can be changed to bevel gear 7 transmission, the rotating main shaft 2 drives the large bevel gear to rotate, the large bevel gear drives the small bevel gear to rotate, and the small bevel gear is fixed to a rotating wheel at the bottom, thereby driving the rotating wheel to move back and forth.

[0125] At the same time, the rotating wheel can also be replaced by a wheel hub, which can be directly driven to move. This solution does not require any track 5 and can achieve omnidirectional movement.

[0126] In some embodiments, optionally, the steering drive uses a chain 122 to pull the turntable to rotate left and right, which can be replaced by a bevel gear 7 transmission.

[0127] In some embodiments, the chain drive may optionally be replaced with a gear or pulley drive.

[0128] In some embodiments, optionally, in order to balance the torque during walking and turning so that the top plate remains stable, the multi-directional shuttle transport device can be arranged and used symmetrically.

[0129] In some embodiments, optionally, when the multi-directional shuttle transport device is used alone, support wheels or slide grooves can be used on the left and right sides of the top plate to contact the fixed frame or track 5, and the torque generated during the movement can also be offset. When in the rotating position, the support wheel or slide groove can realize 90° reciprocating motion. When the bottom turntable is driven, it can synchronously drive the support wheel or slide groove to move back and forth, thereby balancing the torque generated during the steering process.

[0130] The following is an introduction to the working principle of the multi-directional shuttle transport device:

[0131] The top platform is fixed, and the sprocket and the driving gear are connected to the rotating main shaft through the keyway. The rotation of the sprocket drives the rotating main shaft to rotate, and then drives the driving gear to rotate. The driving gear and the rotating main shaft are axially positioned through the stepped shaft and the shaft retaining ring. Since the rack is fixed on the track, the driving gear and the rack are meshed with each other. When the driving gear rotates, the rack and the track remain fixed, so the traveling wheel train can be driven to move forward and backward along the track to realize the forward and backward movement of the trolley. When the trolley reaches the turning position, another chain pulls the chain plate on the turntable to rotate left and right, thereby driving the traveling wheel train to rotate. At this time, the lower part of the track at the turning position is provided with a rotating table (transfer track). The rotation of the traveling wheel train can drive the lower track to rotate synchronously, thereby realizing the turning.

[0132] The following is a specific example to further illustrate the workflow:

[0133] In a specific embodiment, if Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, when two groups of four-way shuttles (multi-directional shuttle transport devices) are arranged symmetrically along the center line, and the racks on the tracks corresponding to the two groups of four-way shuttles are set on one side (for example, the rack on the track corresponding to the left four-way shuttle is set on the left side of the track, and the rack on the track corresponding to the right four-way shuttle is set on the left side of the track), the right-angle reduction motor (drive assembly) and the drive sprocket are arranged at the top, and the right-angle reduction motor drives the drive sprocket to cooperate with the sprockets on the left and right four-way shuttles through the chain. In the walking state, the rotation direction of the left and right reduction motors can be set to the same direction. For example, when the left reduction motor rotates clockwise, the drive sprocket rotates, and then drives the left rotating spindle to rotate clockwise, the drive gear of the left four-way shuttle engages with the rack on the left side of the track, and the wheels move forward. At this time, the reduction motor on the right also rotates clockwise, and then drives the right rotating spindle to rotate clockwise, the drive gear of the right four-way shuttle engages with the rack on the left side of the track, and the wheels also move forward.

[0134] Among them, the racks on the tracks corresponding to the two groups of four-way shuttles can also be symmetrically arranged on the left and right sides (for example, the racks on the tracks corresponding to the left four-way shuttle are arranged on the left side of the track, and the racks on the tracks corresponding to the right four-way shuttle are arranged on the right side of the track). At this time, in the walking state, the rotation direction of the left and right reduction motors can be set to the opposite direction. For example, when the left reduction motor rotates clockwise, the drive sprocket rotates, thereby driving the left rotating spindle to rotate clockwise, the drive gear of the left four-way shuttle engages with the rack on the left side of the track, and the wheel moves forward. The reduction motor on the right rotates counterclockwise, thereby driving the right rotating spindle to rotate counterclockwise, the drive gear of the right four-way shuttle engages with the rack on the right side of the track, and the wheel also moves forward. When this solution is used in practice, in order to ensure that the two four-way shuttles can travel normally on the same track, the rotating spindles of the two four-way shuttles are usually staggered to ensure that the drive gear of each four-way shuttle can cooperate with its corresponding rack, and avoid one drive gear from cooperating with the racks on both sides at the same time. Among them, no matter the racks are set on one side, or on the left and right sides, the travel motor and the steering motor can be set as brake motors. At this time, when the four-way shuttle moves forward, since the four sets of motors are installed on the top plate, the rotational torque generated by walking can be balanced by the braking torque of the steering motor (the principle is as follows: when the travel motor drives the walking, the steering motor controls the transmission disc to remain stationary. Since the steering motor is set on the loading platform, the loading platform and the transmission disc can remain relatively stationary, thereby balancing the torque generated during walking). Similarly, the rotational torque generated during steering can also be balanced by the braking torque of the travel motor. That is, the rack position can be arranged arbitrarily, as long as the forward direction is consistent. If arranged on the same side, the motors rotate in the same direction, and if arranged symmetrically, the rotation directions are opposite.

[0135] like Figure 7 and Figure 8 As shown, when the four-way shuttle moves to the rotating position (transfer track), at this time, the bottom track of the four-way shuttle is rotatable, and a turntable is provided at the bottom of the track. The reduction motor and sprocket at the bottom drive the chain. The left and right sides of both ends of the chain are connected to the chain plate on the four-way shuttle to achieve steering. There is no need to specify a specific direction when turning. It is only necessary to ensure that the forward direction of the trolley is consistent after turning. The rotational torque can be balanced by the braking torque of the travel motor. For example, the motor rotation direction can be set to reverse. When the left reduction motor rotates clockwise, the left turntable rotates clockwise, and then drives the track (transfer track) to rotate clockwise. At the same time, the right reduction motor rotates counterclockwise, which drives the track (transfer track) to rotate counterclockwise, achieving torque balance and completing the reversal. The state of the four-way shuttle changes from. Fig. 9 becomes Fig.10 In this embodiment, the track can only rotate when in the turning position. In the normal walking state, the track is fixed.

[0136] like Fig.11 As shown, the directional wheel in the traveling wheel system can also be replaced with a hub motor, so that the gear rack can be eliminated, so that the multi-directional shuttle transport device can travel in any direction. Similarly, its torque balance is the same as the above embodiment, and can be achieved by the traveling motor and the steering motor.

[0137] The beneficial effects of this application are as follows:

[0138] 1. The inner and outer rings of the cross roller bearing cooperate with each other to make the structure more compact, and the whole machine can be enlarged or reduced as needed.

[0139] 2. The conventional commutation scheme with vertical arrangement of the wheel train has been abandoned. Both driving and commutation can move relatively independently. The commutation is performed by a rotating track, which increases the response speed during the steering process.

[0140] 3. The steering drive uses a sprocket to pull the chain plate on the turntable to rotate. The structure is simple and reliable, and the manufacturing cost is low. When the four-way shuttle car is enlarged or reduced according to actual needs, the steering solution will not increase the manufacturing cost much.

[0141] 4. Two four-way shuttle vehicles can be arranged symmetrically and driven synchronously to balance the torque generated during walking and turning and enhance the stability of movement.

[0142] 5. The structure is simple and compact, and all common parts on the market are used, which reduces the production cost.
