Description

Technical Field

[0001] The present invention belongs to the technical field of automated logistics transportation, and relates to a power transmission mechanism that can float and expand / contract, a transmission method, and a transportation device. Background Art

[0002] In modern automated logistics systems, highly flexible logistics equipment such as shuttles, automated guided vehicles (AGVs), and automated storage and retrieval systems (AS / RS) often need to dynamically dock with fixed or semi-fixed conveyor lines to achieve efficient and automated transfer of goods. To achieve this docking and conveying, the commonly adopted technical solution is to install a power sending mechanism at the access end of the mobile device or warehouse, and install a power receiving mechanism at the end of the corresponding docking conveyor line. When the device reaches the specified docking position, the power sending mechanism and the power receiving mechanism are physically connected through a mechanical interface and transmit power, thereby driving the conveyor line to operate.

[0003] However, in the existing power docking and transmission solution, at the moment when the power sending mechanism and the power receiving mechanism are separated, the power receiving mechanism often continues to rotate freely due to inertia or the gravity of the residual goods on the conveyor line. Although a few solutions provide a rotation stopping function, these devices usually require an additional independent power source and control signal to actively release the locked state, which greatly increases the complexity of the system and the operation steps, resulting in inaccurate positioning of the goods, phenomena such as outward sliding or rolling, and there are safety risks. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the existing power docking and transmission solution that there is a lack of a good rotation stopping function or the rotation stopping function is complicated to operate, resulting in inaccurate positioning of the goods, phenomena such as outward sliding or rolling, and there are safety risks, and to provide a power transmission mechanism that can float and expand / contract, a transmission method, and a transportation device.

At this time, the anti-rotation mechanism is separated from the input end of the power receiving mechanism, and the output end of the power receiving mechanism is connected to the input end of the power transmission mechanism;

[0010] When the power transmission mechanism is separated from the power receiving mechanism, the anti-rotation mechanism resets and the power transmission terminates. At this time, the anti-rotation mechanism is connected to the input end of the power receiving mechanism.

[0011] A further improvement of the present invention lies in:

[0012] The power receiving mechanism includes a mounting plate, a passive gear is arranged on the mounting plate, and a docking bearing is arranged on the side wall of the passive gear;

[0013] The anti-rotation mechanism includes a support block, the support block is hinged to the mounting plate, the support block is provided with a tension spring, one end of the tension spring is connected to the support block, and the other end is connected to the mounting plate;

[0014] A rotation-stop block is arranged on the support block, and rotation-stop teeth corresponding to the passive gear are provided on the rotation-stop block;

[0015] It further includes a separation block, the separation block is connected to the support block, a rotation-stop bearing is arranged at the end of the separation block far from the support block. When the rotation-stop teeth are engaged with the passive gear, the side wall of the rotation-stop bearing abuts against the side wall of the docking bearing.

[0016] A docking guide block is arranged at the end of the power transmission mechanism, and a docking guide groove and a separation block pushing groove are provided at the end of the docking guide block;

[0017] When the rotation-stop teeth are engaged with the passive gear, the docking guide groove is located outside the docking bearing, and the separation block pushing groove can push the separation block to separate from the docking bearing. At this time, the support block rotates counterclockwise along the mounting plate.

[0018] The power transmission mechanism includes a docking plate, the docking guide blocks are symmetrically arranged at both ends of the docking plate, and driving gears are arranged at positions near both ends of the docking plate. The driving gears are connected to a rotational power source. When the power transmission mechanism is connected to the power receiving mechanism, the driving gears are engaged with the passive gear;

[0019] The docking plate is connected to a slider, the slider slides along a linear guide, and the docking plate is connected to a telescopic power source.

[0020] A telescopic floating mechanism is arranged on the docking plate. The telescopic floating mechanism includes a power block, a spring shaft installation groove is provided on the power block, a spring shaft penetrates through the spring shaft installation groove, and two floating springs are symmetrically arranged on the spring shaft.

[0024] Three sliders are arranged, one of the sliders is connected to the telescopic floating mechanism, and the other two sliders are symmetrically arranged on both sides of the telescopic floating mechanism.

[0025] The rotary power source is connected to a sprocket through a chain, and the sprocket is connected to a driving gear.

[0026] A transportation device with a power transmission mechanism capable of floating and telescoping includes a driving conveying device and a driven conveying device. The power sending mechanism according to any one of the present inventions is installed on the driving conveying device, and the power receiving mechanism according to any one of the present inventions is installed on the driven conveying device.

[0027] A power transmission method of the power transmission mechanism according to any one of the present inventions includes the following steps:

[0028] Drive the power sending mechanism to gradually approach the power receiving mechanism. The power sending mechanism gradually pushes the anti-rotation mechanism to rotate along the power receiving mechanism. When the output end of the power sending mechanism meshes with the input end of the power receiving mechanism, the anti-rotation mechanism is separated from the power receiving mechanism, and power transmission starts.

[0029] When the power sending mechanism gradually disengages from the power receiving mechanism, the anti-rotation mechanism gradually resets until the power sending mechanism is completely disengaged from the power receiving mechanism, and the anti-rotation mechanism is connected to the input end of the power receiving mechanism.

[0031] The present invention discloses a power transmission mechanism capable of floating and telescoping. An anti-rotation mechanism is arranged on the power receiving mechanism. When the power sending mechanism is docked with the power receiving mechanism, the lock is automatically released to transmit power. At the moment when the power sending mechanism is separated from the power receiving mechanism, the anti-rotation mechanism resets to lock the power receiving end, solving the problem in the prior art that the power receiving end rotates freely after separation or the anti-rotation device depends on additional power operation, effectively preventing the goods from slipping and misalignment of positioning, eliminating potential safety hazards, and reducing the wear of the equipment caused by idling. In this device, the anti-rotation mechanism is directly hinged to the power receiving mechanism, maintaining the overall compactness of the equipment and saving equipment space.

[0032] Furthermore, in the present invention, the tension spring provides a restoring force for the support block to ensure that the anti-rotation teeth that stop rotating immediately engage with the passive gear at the moment of separation, guaranteeing the positioning accuracy. During docking, the power transmission mechanism pushes the bearing, and the support block rotates, gradually driving the anti-rotation block away from the passive gear to release the locking. The unlocking action is naturally triggered by the docking action without the need for electricity, pneumatic power, or manual intervention. After the anti-rotation is released, the passive gear can immediately receive power without delay, and the side wall of the bearing abuts against the side wall of the docking bearing to avoid jamming or impact.

[0033] Furthermore, in the present invention, the push groove of the separation block can push the stop bearing, and then precisely push the separation block, forcing the separation block to drive the support block to rotate counterclockwise to achieve the accuracy of docking.

[0034] The present invention discloses a transportation device with a power transmission mechanism that can float and telescopic. A anti-rotation mechanism is provided on the power receiving mechanism. When the power transmission mechanism is docked with the power receiving mechanism, the lock is automatically released to transmit power. At the moment when the power transmission mechanism is separated from the power receiving mechanism, the anti-rotation mechanism resets to lock the power receiving end, solving the problem in the prior art that the power receiving end rotates freely after separation or the anti-rotation device relies on additional power operation, effectively preventing the goods from slipping and misalignment of positioning, eliminating potential safety hazards, and reducing the wear of the equipment caused by idling. In this device, the anti-rotation mechanism is directly hinged to the power receiving mechanism, maintaining the overall compactness of the equipment and saving equipment space, and is widely applicable to equipment such as shuttle cars, AGVs, and automated storage and retrieval systems that need to dock with conveyor roller lines, belt lines, etc. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0061] The present invention will be further described in detail below with reference to the accompanying drawings:

[0062] Refer to Figures 1 to 18 , an embodiment of the present invention discloses a floating and telescopic power transmission mechanism. This mechanism can be used for rotary power transmission, realizing one-to-many power supply, reducing the input of power sources, and achieving the energy-saving goal; the power sending mechanism is provided with rotary power by a rotary power source, transmits the power to the two-end gears through a chain (belt), etc., and then controls the telescopic moving gear through the mechanism to mesh with the gear of the power receiving mechanism to transmit power. When the telescopic moving gear moves, the rotary power source does not move along with it, reducing energy consumption; the power receiving mechanism receives the rotary power through the gear, and has a stopping device to lock the gear when not connected to the power sending mechanism, preventing the gear from rotating randomly when there is no power; this mechanism can be widely used in equipment such as shuttle cars, AGVs, and automated storage and retrieval systems that need to dock with conveyor roller lines, belt lines, etc., with a simple and stable structure.

[0063] In this mechanism, there is a set of driving gears 12 and docking guiding blocks 8 at each end of the docking plate 11 on the power sending mechanism. The telescopic power source 15 controls the left and right telescopic movement of the docking plate 11 through the gear-rack cooperation. The docking guiding block 8 first opens the stopping mechanism and then guides the docking bearing 7. The driving gear 12 docks with the driven gear 1 to transmit power; the rotary power source transmits the power to the driving gears 12 at both ends of the docking plate 11 through a chain (belt), etc., and drives them to rotate, but does not move along with the docking plate; the floating device accommodates the position error of the power receiving mechanism through the deformation of springs and elastic workpieces.

[0064] Specifically, it includes:

[0065] Refer to Figures 1 to 2 , this embodiment discloses a floating and telescopic power transmission mechanism, including a power sending mechanism 32, and power receiving mechanisms 33 are arranged at both ends of the power sending mechanism 32;

[0066] It further includes a linear guide. The power sending mechanism 32 is slidably connected to the linear guide. When the power sending mechanism moves along the linear guide, the output end of the power sending mechanism 32 can mesh with the input end of the power receiving mechanism 33;

[0067] A stopping mechanism is arranged on the power receiving mechanism 33. The stopping mechanism is hinged to the power receiving mechanism 33. When the power sending mechanism 32 is connected to the power receiving mechanism 33, the power receiving mechanism 33 will push the stopping mechanism to rotate along the power receiving mechanism 33. At this time, the stopping mechanism is separated from the input end of the power receiving mechanism 33. When the power sending mechanism 32 is separated from the power receiving mechanism 33, the stopping mechanism resets, and at this time, the stopping mechanism is connected to the input end of the power receiving mechanism 33.

[0068] Refer to Figures 3 to 5Further, in this embodiment, the specific structures of the power receiving mechanism and the anti-rotation mechanism are as follows:

[0069] The power receiving mechanism includes a mounting plate, on which a passive gear 1 is mounted, and a docking bearing 7 is arranged on the side wall of the passive gear 1.

[0070] Further, in this embodiment, the anti-rotation mechanism includes a support block 2, a tension spring 3, a anti-rotation block 4, a hinge pin 26, a disengaging block 5 and an anti-rotation bearing 6;

[0071] The passive gear 1 meshes and rotates with the driving gear 12 of the power transmission mechanism, and then transmits the rotational power;

[0072] The docking bearing 7 contacts the docking guide block 8 of the power transmission mechanism, and has the function of guiding and positioning;

[0073] The support block 2 of the anti-rotation mechanism is the support main body, and the tension spring 3, the anti-rotation block 4 and the disengaging block 5 are all mounted on the support block 2. One end of the tension spring 3 is connected to the support block 2, and the other end is connected to the mounting plate, on which the passive gear 1 is mounted.

[0074] The anti-rotation block 4 contacts and meshes with the passive gear 1 under the action of the tension spring 3, and can limit the rotation of the passive gear 1. During docking, the docking guide block 8 of the transmission mechanism contacts the disengaging block 5 and the anti-rotation bearing 6, and rotates the anti-rotation block 4 around the hinge pin 26, away from the passive gear 1, and no longer restricts the rotation of the passive gear 1.

[0075] Specifically, a docking guide groove 9 and a disengaging block pushing groove 10 are formed at the end of the docking guide block 8. During docking, the docking guide groove 9 is gradually connected and matched with the docking bearing 7, and the disengaging block pushing groove 10 gradually pushes the anti-rotation bearing 6, further driving the disengaging block 5 to move. At this time, the support block 2 rotates counterclockwise around the hinge pin 26, and the anti-rotation block 4 is separated from the passive gear 1. The disengaging block 5 pulls the spring 3 during the rotation process, and the passive gear 1 meshes and rotates with the driving gear 12 of the power transmission mechanism, and then transmits the rotational power.

[0076] When separating, the docking guide groove 9 and the disengaging block pushing groove 10 start to separate from the passive gear 1. At this time, under the action of the spring 3, it starts to reset. At this time, the support block 2 rotates clockwise around the hinge pin 26, and the anti-rotation block 4 gradually approaches the passive gear 1. When the docking guide block 8 is completely separated from the passive gear 1, the anti-rotation block 4 meshes with the passive gear 1.

[0077] See Figures 6 to 7 , Further, in this embodiment, the specific structure of the power transmission mechanism is as follows:

[0078] The telescopic power source 15 controls the left and right telescopic movement of the docking plate 11 through the cooperation of a gear and a rack. There is a set of driving gears 12 and docking guide blocks 8 at both ends of the docking plate 11. The rack 20 maintains linear motion through a set of linear rails 14 and sliders 13, and then provides the power for the left and right movement of the docking plate 11 through a telescopic floating mechanism. The telescopic floating mechanism uses two floating springs 18 for elastic floating. When docking with the power receiving mechanism, the floating springs 18 are compressed, so that the driving gears 12 are pressed on the driven gear 1 by the force of the floating springs 18, and the distance errors between multiple power receiving mechanisms and the power sending mechanism are elastically accommodated by the floating springs 18.

[0079] See Figures 8 to 14 Further, in this embodiment, the specific structure of the telescopic floating mechanism is as follows:

[0080] The telescopic floating mechanism includes a power block 16, floating springs 18, floating blocks 19, and spring shafts 17; among them, the power block 16 is fixed to the rack 20 and moves together with the rack 20, and the floating blocks 19 are fixed to the docking plate 11 and move together with the docking plate 11.

[0081] When the power block 16 moves, it first compresses the floating springs 18, and then the floating springs 18 provide a force to the floating blocks 19 and drive the floating blocks 19 and the docking plate 11 to move. After the power block 16 moves in place, due to the differences in the positions of each power receiving mechanism, the displacements of the docking plate 11 will also be different, and the distances between the floating blocks 19 and the power block 16 will also be different, that is, the spring compression amounts are different when docking with different power receiving mechanisms, so as to accommodate the distance errors between different mechanisms.

[0082] There is a set of floating springs 18 and floating blocks 19 on both the left and right sides of the power block 16, which can accommodate the distance errors on both sides; the spring shafts 17 pass through the floating springs 18 to limit the positions of the floating springs 18 and prevent the floating springs 18 from popping out. The spring shafts 17 are in clearance fit with the power block 16. Specifically, spring shaft installation grooves are opened on the power block 16, and the spring shafts 17 penetrate through the spring shaft installation grooves, and the floating blocks 19 are located at both ends of the spring shafts 17.

[0083] See Figures 10 to 14 , Further, in this embodiment, the installation of the docking plate and the slider is as follows:

[0084] The docking plate 11 is floatingly connected to the linear guide 14 and the slider 13, which can accommodate the height error of the power receiving mechanism. There are three sliders 13, one of which is connected to the telescopic floating mechanism, and the other two sliders are symmetrically arranged on both sides of the telescopic floating mechanism. Among the sliders 13 on both sides, a set of equal-height bolts 21 and gaskets 23 are installed on any one slider to fix the docking plate 11 to the slider 13 with a clearance fit. The docking plate 11 can move offset relative to the slider 13 to meet the alignment error during docking. When the high bolts 21 and gaskets 23 are installed on both sliders 13 on both sides, the offset and movement of the docking plate 11 are restricted. The elastic bushing 22 can keep the docking plate 11 in the middle position when there is no external force. When there is an external force, the elastic bushing 11 is compressed, and the docking plate can move relative to the linear guide 14 to achieve the accommodation of the height error of the power receiving mechanism.

[0085] Further, in this embodiment, the power sending mechanism provides power for the driving gear 12 through a rotary power source. The working principle of the rotary power source is as follows:

[0086] The rotary power source transmits the power to the driving gears 12 at both ends of the docking plate 11 through the chain 24 and drives them to rotate; there is a sprocket 25 at each end of the docking plate 11, and the sprocket 25 is connected to the driving gear 12 to transmit power; it also includes a bottom plate 27, on which a rotary power source 28, a limiting idler 29, an auxiliary idler 30 and a tensioning idler 31 are fixed, and none of them move with the docking plate 11;

[0087] The limiting idler 29 makes the part of the chain 24 on the docking plate 11 arranged in parallel. In this way, when the docking plate 11 moves left and right, the perimeter of the chain 24 will not change, and the rotary power source 28 does not need to change its position; the tensioning idler 31 can adjust the tightness of the chain 24 and improve the service life of the chain 24.

[0088] Further, the chain 24 in this embodiment is a belt.

[0089] Further, in this embodiment, the rotary power source 28 is a motor, and the power is transmitted through the chain 24 by the gear at the output end.

[0090] See Figures 15 to 18 , further, the working principle of this embodiment is as follows:

[0091] The power sending mechanism is driven by an external mechanism (the external mechanism includes a moving module or an AGV) to move to the docking position of the power receiving mechanism;

[0092] The power sending mechanism extends the docking plate 11. The docking guide block 8 on the power sending mechanism opens the anti-rotation mechanism of the power receiving mechanism. The driving gear 12 on the power sending mechanism rotates and meshes with the driven gear 1 of the power receiving mechanism to start transmitting the rotary power;

[0093] When the driving gear 12 on the power transmission mechanism stops rotating, the docking plate 11 is retracted, and the rotation stopping mechanism of the power receiving mechanism restricts the rotation of the driven gear 1, and the rotation power transmission ends;

[0094] The power transmission mechanism is driven by an external mechanism (such as a mobile module, an AGV, etc.) to move to the docking position of other power receiving mechanisms, and a new round of power transmission begins

[0095] This mechanism is stable, reliable, simple in structure and easy to maintain. This mechanism can be widely used in equipment such as shuttle cars, AGVs, and automated warehouses that need to dock with conveyor roller lines, belt lines, etc.

[0096] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
