Description

Technical Field

[0001] This invention belongs to the field of automated logistics transportation technology, and relates to a floating and retractable power transmission mechanism, transmission method and transportation equipment. Background Technology

[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 cargo transfer. To achieve this docking, a common technical solution is to install a power transmitting mechanism at the storage and retrieval end of the mobile equipment or warehouse, and a power receiving mechanism at the end of the corresponding docking conveyor line. When the equipment reaches the designated docking position, the power transmitting mechanism and the power receiving mechanism physically connect through a mechanical interface to transmit power, thereby driving the conveyor line.

[0003] However, in existing power docking transmission schemes, the power receiving mechanism often continues to rotate freely due to inertia or the gravity of residual cargo on the conveyor line at the moment of separation between the power transmitting and receiving mechanisms. While a few solutions provide anti-rotation functionality, these devices typically require an additional independent power source and control signal to actively unlock the system. This significantly increases the complexity of the system and the number of operational steps, potentially leading to mispositioning of the cargo, external slippage or rolling, and posing safety risks. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in existing power docking transmission schemes that lack a good anti-rotation function or have a complicated anti-rotation function, which leads to inaccurate positioning of goods, external slippage or rolling, and safety risks. The invention provides a floating and retractable power transmission mechanism, transmission method and transportation equipment.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A floating and retractable power transmission mechanism includes a power transmitting mechanism, and power receiving mechanisms are provided at both ends of the power transmitting mechanism;

[0007] It also includes a linear rail, and the power transmitting mechanism is slidably connected to the linear rail. When the power transmitting mechanism moves along the linear rail, the output end of the power transmitting mechanism can engage with the input end of the power receiving mechanism.

[0008] The power receiving mechanism is provided with an anti-rotation mechanism, which is hinged to the power receiving mechanism.

[0009] When the power transmitting mechanism is connected to the power receiving mechanism, the power receiving mechanism pushes the anti-rotation mechanism to rotate along the power receiving mechanism. 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 transmitting mechanism.

[0010] When the power transmitting mechanism separates 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 is that:

[0012] The power receiving mechanism includes a mounting plate, a driven gear is provided on the mounting plate, and a mating bearing is provided on the side wall of the driven gear;

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

[0014] An anti-rotation block is provided on the support block, and the anti-rotation block has anti-rotation teeth corresponding to the driven gear;

[0015] It also includes a release block, which is connected to the support block. An anti-rotation bearing is provided at the end of the release block away from the support block. When the anti-rotation tooth meshes with the driven gear, the side wall of the anti-rotation bearing abuts against the side wall of the mating bearing.

[0016] The end of the power transmission mechanism is provided with a docking guide block, and the end of the docking guide block is provided with a docking guide groove and a disengagement block pushing groove;

[0017] When the anti-rotation tooth meshes with the driven gear, the docking guide groove is located outside the docking bearing, and the release block pushing groove can push the release block to separate from the docking bearing. At this time, the support block rotates counterclockwise along the mounting plate.

[0018] The power transmitting mechanism includes a docking plate, and docking guide blocks are symmetrically arranged at both ends of the docking plate. A drive gear is arranged near both ends of the docking plate. The drive gear is connected to a rotating power source. When the power transmitting mechanism is connected to the power receiving mechanism, the drive gear meshes with the driven gear.

[0019] The docking plate is connected to the slider, the slider is slidably connected to the linear rail, and the docking plate is connected to the telescopic power source.

[0020] The docking plate is provided with a telescopic floating mechanism, which includes a power block. A spring shaft mounting groove is opened on the power block. A spring shaft passes through the spring shaft mounting groove. Two floating springs are symmetrically arranged on the spring shaft and are symmetrically distributed at both ends of the spring shaft mounting groove.

[0021] Floating blocks are provided at both ends of the spring shaft, and the floating blocks are connected to the docking plate;

[0022] A rack is provided on the power block, and the rack is connected to a telescopic power source.

[0023] The docking plate and the slider are connected by equal-height bolts, and an elastic bushing and a washer are sequentially fitted on the outer side of the equal-height bolts.

[0024] There are three sliders, 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.

[0025] The rotational power source is connected to a sprocket via a chain, and the sprocket is connected to a drive gear.

[0026] A transport device with a floating and retractable power transmission mechanism includes an active conveying device and a driven conveying device. The active conveying device is equipped with the power transmitting mechanism according to any one of the present invention, and the driven conveying device is equipped with the power receiving mechanism according to any one of the present invention.

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

[0028] The driving power transmitting mechanism gradually approaches the power receiving mechanism, and the power transmitting mechanism gradually pushes the anti-rotation mechanism to rotate along the power receiving mechanism. When the output end of the power transmitting mechanism engages with the input end of the power receiving mechanism, the anti-rotation mechanism separates from the power receiver, and power transmission begins.

[0029] As the power transmitting mechanism gradually disengages from the power receiving mechanism, the anti-rotation mechanism gradually resets until the power transmitting mechanism and power receiving mechanism are completely disengaged, at which point the anti-rotation mechanism connects to the input end of the power receiving mechanism.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] This invention discloses a floating and retractable power transmission mechanism. An anti-rotation mechanism is installed on the power receiving mechanism. When the power transmitting mechanism and the power receiving mechanism are connected, the mechanism automatically unlocks to transmit power. At the instant the power transmitting mechanism and the power receiving mechanism separate, the anti-rotation mechanism resets and locks the power receiving end. This solves the problems of free rotation of the power receiving end after separation or the reliance on additional power for the anti-rotation device in existing technologies. It effectively prevents cargo slippage and positioning inaccuracies, eliminates safety hazards, and reduces wear 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 space.

[0032] Furthermore, in this invention, the tension spring provides a restoring force to the support block, ensuring that the anti-rotation teeth that stop rotating at the moment of separation immediately engage the passive gear, thus guaranteeing positioning accuracy. During docking, the power transmission mechanism pushes the bearing, causing the support block to rotate and gradually disengage the anti-rotation block from the passive gear, releasing the lock. The unlocking action is naturally triggered by the docking action, requiring no electric, pneumatic, or manual intervention. After the anti-rotation is released, the passive gear can immediately receive power without delay, and the sidewall of the bearing abuts against the sidewall of the docking bearing, avoiding jamming or impact.

[0033] Furthermore, in this invention, the release block push groove can push the stop bearing, thereby precisely pushing the release block, forcing the release block to drive the support block to rotate counterclockwise, thus achieving precise docking.

[0034] This invention discloses a transportation device with a floating and retractable power transmission mechanism. An anti-rotation mechanism is installed on the power receiving mechanism. When the power transmitting mechanism and the power receiving mechanism are docked, the anti-rotation mechanism automatically releases the lock to transmit power. At the instant the power transmitting mechanism and the power receiving mechanism separate, the anti-rotation mechanism resets and locks the power receiving end. This solves the problems of free rotation of the power receiving end after separation or the reliance on additional power for the anti-rotation device in existing technologies. It effectively prevents cargo slippage and positioning inaccuracies, eliminates safety hazards, and reduces wear 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 space. It is widely applicable to shuttle cars, AGVs, automated warehouses, and other equipment that requires docking with conveyor rollers, belt conveyors, etc. Attached Figure Description

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0056] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0057] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0058] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0059] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0060] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

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

[0062] See Figures 1 to 18 This invention discloses a floating and retractable power transmission mechanism. This mechanism can be used for rotary power transmission and can achieve one-to-many power supply, reducing the investment in power sources and achieving energy-saving goals. The power transmitting mechanism is provided with rotary power by a rotary power source, and the power is transmitted to the gears at both ends through chains (belts), etc. The mechanism then controls the retractable movement of the gears to mesh with the gears of the power receiving mechanism to transmit power. When the retractable movement of the gears occurs, the rotary power source does not move with it, reducing energy consumption. The power receiving mechanism receives rotary power through gears. When not connected to the power transmitting mechanism, an anti-rotation device locks the gears to prevent them 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 require docking with conveyor rollers, belts, etc. It has a simple structure and is stable.

[0063] In this mechanism, each end of the docking plate 11 on the power transmitting mechanism has a set of driving gears 12 and docking guide blocks 8. The telescopic power source 15 controls the telescopic movement of the docking plate 11 by means of gears and racks. The docking guide block 8 first opens the anti-rotation mechanism and then guides the docking bearing 7. The driving gears 12 dock with the driven gears 1 to transmit power. The rotational power source transmits power to the driving gears 12 at both ends of the docking plate 11 through chains (belts) and drives them to rotate, but does not move with the docking plate. The floating device uses the deformation of springs and elastic workpieces to accommodate the positional error of the power receiving mechanism.

[0064] Specifically, it includes:

[0065] See Figures 1 to 2 This embodiment discloses a floating and retractable power transmission mechanism, including a power transmitting mechanism 32, and power receiving mechanisms 33 are provided at both ends of the power transmitting mechanism 32;

[0066] It also includes a linear rail, and the power transmitting mechanism 32 is slidably connected to the linear rail. When the power transmitting mechanism moves along the linear rail, the output end of the power transmitting mechanism 32 can engage with the input end of the power receiving mechanism 33.

[0067] An anti-rotation mechanism is provided on the power receiving mechanism 33. The anti-rotation mechanism is hinged to the power receiving mechanism 33. When the power transmitting mechanism 32 is connected to the power receiving mechanism 33, the power receiving mechanism 33 will push the anti-rotation mechanism to rotate along the power receiving mechanism 33. At this time, the anti-rotation mechanism is separated from the input end of the power receiving mechanism 33. When the power transmitting mechanism 32 is separated from the power receiving mechanism 33, the anti-rotation mechanism is reset and then connected to the input end of the power receiving mechanism 33.

[0068] See Figures 3 to 5Furthermore, 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 driven gear 1 is mounted, and a mating bearing 7 is provided on the side wall of the driven gear 1.

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

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

[0072] The docking bearing 7 contacts the docking guide block 8 of the power transmission mechanism, which serves as a guide and positioner.

[0073] The support block 2 of the anti-rotation mechanism is the main support body. The tension spring 3, the anti-rotation block 4 and the release block 5 are all installed 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. The passive gear 1 is installed on the mounting plate.

[0074] The anti-rotation block 4 contacts and meshes with the driven gear 1 under the force of the tension spring 3, which can restrict the rotation of the driven gear 1. During docking, the docking guide block 8 of the sending mechanism contacts the disengagement block 5 and the anti-rotation bearing 6, and rotates the anti-rotation block 4 around the hinge pin 26 away from the driven gear 1, no longer restricting the rotation of the driven gear 1.

[0075] Specifically, the end of the docking guide block 8 is provided with a docking guide groove 9 and a release block pushing groove 10. During docking, the docking guide groove 9 gradually connects and cooperates with the docking bearing 7, and the release block pushing groove 10 gradually pushes the anti-rotation bearing 6, further driving the release block 5 to move. At this time, the support block 2 rotates counterclockwise around the hinge pin 26, the anti-rotation block 4 separates from the driven gear 1, and the release block 5 pulls the spring 3 during rotation. The driven gear 1 meshes and rotates with the driving gear 12 of the power transmission mechanism, thereby transmitting rotational power.

[0076] When the separation occurs, the docking guide groove 9 and the disengagement block push groove 10 begin to separate from the driven gear 1. At this time, under the action of the spring 3, the reset begins. At this time, the support block 2 rotates clockwise around the hinge pin 26, and the anti-rotation block 4 gradually approaches the driven gear 1 until the docking guide block 8 is completely separated from the driven gear 1, at which point the anti-rotation block 4 meshes with the driven gear 1.

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

[0078] The telescopic power source 15 controls the telescopic left and right movement of the docking plate 11 through a gear and rack mechanism. Each end of the docking plate 11 has a set of driving gears 12 and docking guide blocks 8. The rack 20 maintains linear motion through a set of linear rails 14 and sliders 13. The telescopic floating mechanism provides the power for the left and right movement of the docking plate 11. 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 gear 12 is pressed against the passive gear 1 by the force of the floating springs 18. The elasticity of the floating springs 18 is used to accommodate the distance error between multiple power receiving mechanisms and power sending mechanisms.

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

[0080] The telescopic floating mechanism includes a power block 16, a floating spring 18, a floating block 19, and a spring shaft 17; wherein, the power block 16 is fixed together with the rack 20 and moves together with the rack 20, and the floating block 19 is fixed on the docking plate 11 and moves together with the docking plate 11.

[0081] When the power block 16 moves, it first compresses the floating spring 18, and then the floating spring 18 provides force to the floating block 19, which drives the floating block 19 and the docking plate 11 to move. After the power block 16 moves to its position, the displacement of the docking plate 11 will also be different due to the different positions of each power receiving mechanism. The distance between the floating block 19 and the power block 16 will also be different. That is, the spring compression is different when docking different power receiving mechanisms, so as to accommodate the distance error between different mechanisms.

[0082] The power block 16 has a set of floating springs 18 and floating blocks 19 on each of its left and right sides, which can accommodate the distance error on the left and right sides; the spring shaft 17 passes through the floating spring 18, limits the position of the floating spring 18, and prevents the floating spring 18 from popping out. The spring shaft 17 is clearance-fitted with the power block 16. Specifically, the power block 16 has a spring shaft mounting groove, and the spring shaft 17 passes through the spring shaft mounting groove. The floating blocks 19 are located at both ends of the spring shaft 17.

[0083] See Figures 10 to 14 Furthermore, 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 slider is connected to the telescopic floating mechanism, and the other two sliders are symmetrically arranged on both sides of the telescopic floating mechanism. On either of the two sliders 13, a set of equal height bolts 21 and shims 23 are installed to fix the docking plate 11 to the slider 13 with a clearance fit. The docking plate 11 can offset and move relative to the slider 13 to meet the alignment error during docking. When equal height bolts 21 and shims 23 are installed on both sliders 13, the offset and movement of the docking plate 11 are restricted. The elastic bushing 22 can keep the docking plate 11 in the center 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 accommodate the error in the height direction of the power receiving mechanism.

[0085] Furthermore, in this embodiment, the power transmission mechanism provides power to the drive gear 12 through a rotating power source. The working principle of the rotating power source is as follows:

[0086] The rotary power source transmits power to the drive gears 12 at both ends of the docking plate 11 via the chain 24 and drives them to rotate. There is a sprocket 25 at each end of the docking plate 11. The sprocket 25 is connected to the drive gear 12 to transmit power. It also includes a base plate 27. The base plate 27 is fixed with a rotary power source 28, a limiting idler wheel 29, an auxiliary idler wheel 30 and a tensioning idler wheel 31, none of which move with the docking plate 11.

[0087] The limiting idler wheel 29 makes the chain 24 partially parallel on the docking plate 11, so that when the docking plate 11 moves left and right, the circumference of the chain 24 will not change, and the rotation power source 28 will not need to change position; the tensioning idler wheel 31 can adjust the tension of the chain 24 and improve the service life of the chain 24.

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

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

[0090] See Figures 15 to 18 Furthermore, the operating principle in this embodiment is as follows:

[0091] The power transmitting mechanism moves to the docking position of the power receiving mechanism under the drive of an external mechanism (including a mobile module or AGV);

[0092] The power transmitting mechanism extends the docking plate 11, the docking guide block 8 on the power transmitting mechanism opens the anti-rotation mechanism of the power receiving mechanism, the driving gear 12 on the power transmitting mechanism rotates and meshes with the passive gear 1 of the power receiving mechanism, and begins to transmit rotational power.

[0093] When the drive gear 12 on the power transmitting mechanism stops rotating, the docking plate 11 retracts, and the anti-rotation mechanism of the power receiving mechanism restricts the rotation of the passive gear 1, thus ending the rotational power transmission.

[0094] Driven by external mechanisms (mobile modules, AGVs, etc.), the power transmitting mechanism moves to the docking position of other power receiving mechanisms, starting a new round of power transmission.

[0095] This mechanism is stable and reliable, with a simple structure and easy maintenance. It can be widely used in equipment such as shuttle cars, AGVs, and automated warehouses that require docking with conveyor rollers, belt conveyors, etc.

[0096] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
