Description

Technical Field

[0001] This invention relates to the field of non-standard mechanical automation technology, specifically to a transfer device for unlocking, conveying, and transmitting power in a small space. Background Technology

[0002] In a certain conveyor production line, the workpieces are densely arranged, occupying a limited space. To ensure the quantity of workpieces meets targets, the transport space and transfer station space are extremely limited. The workpieces being transferred weigh up to 400 kg, are 1.2 m long and 0.6 m wide, and are stacked side-by-side on shelves. Considering the reliability of the workpiece storage environment (requiring high reliability, maintainability, and simplified control for the entire production line), the shelves must be free of internal power sources. Power for workpiece transfer must be entirely provided by an external transfer device, transmitting torque through a power transmission interface on the shelves. The shelves must have a locking and limiting function for the workpieces, and the transfer device must unlock the shelves before the workpieces leave the warehouse. Unlocking the shelves can be achieved through a horizontal push mechanism. The shelf unlocking interface also requires the transfer device to have both transport and workpiece limiting functions. Market research shows that existing transfer devices cannot unlock the shelf locking mechanism and provide an external power source for the shelves within a small space. Therefore, inventing a transfer device that unlocks and transmits power within a small space is a key challenge for the conveyor production line.

[0003] This invention, taking into account limited space, combines unlocking and power transmission actions. While achieving unlocking and power transmission functions, it reduces the number of motors, improves the reliability of the transfer device, and lowers the space requirements. This invention fundamentally solves the problem of unlocking, conveying, and transmitting power in small spaces. Summary of the Invention

[0004] The purpose of this invention is to provide a transfer device that unlocks, conveys, and transmits power within a confined space. The technical problem it addresses is that the workpieces being transferred on production lines are heavy and large, and the storage racks are purely mechanical structures without a power source, which current transfer devices on the market cannot meet. This invention combines the extended unlocking and power transmission interfaces, merges the power sources for the transfer device's conveying and power transmission functions, and unifies the control of the transfer device's dual-sided locking function. This achieves unlocking, locking, conveying, and power transmission functions within a limited space, while reducing the number of motors to improve the reliability of the transfer device and reduce the required space.

[0007] The unlocking assembly 3 includes an unlocking motor 12, a gear belt b13, an unlocking rod 14, a bearing seat b18, and a ball screw 22.

The ball screw 22 is sleeved on the ball sleeve 28. The bearing seat b18 is installed on the ball screw 22 for support, and its two ends are connected to the unlocking rod 14. In the unlocking assembly, the unlocking motor 12 drives the gear belt b13 to rotate, thereby causing the ball sleeve 28 to rotate. By fixing the ball sleeve 28, the ball screw 22 can generate linear lateral movement.

[0008] The power transmission assembly 4 includes a power transmission rod 15, a bearing seat c25, a conveyor motor 19, a sprocket and chain 20, and an output shaft b23. The conveyor motor 19 and the bearing seat c25 are fixed on the frame 1. The conveyor motor 19 and the output shaft b23 are connected by the sprocket and chain 20. The bearing seat c25 is installed on the output shaft b23 for support, and its two ends are respectively connected to the power transmission rod 15. The power transmission rod 15 realizes rotational power transmission through the power of the conveyor motor 19, and extends together with the unlocking rod 14 through the power of the unlocking motor 12 to complete the interface docking.

[0009] The power transmission rod 15 and the unlocking rod 14 are connected together by a combination plate 16; the unlocking rod 14 is connected to the shelf unlocking interface 26; the power transmission rod 15 is connected to the shelf power input interface 27.

[0010] The conveying assembly 5 includes a conveying roller 17 and a bevel gear 24, the edges of which are perpendicularly connected. The bevel gear 24 is fixed on the output shaft b23 and rotates through the power output by the conveying motor 19, thereby driving the conveying roller 17 to rotate.

[0011] The beneficial effects of this invention are as follows: Based on the transfer space, this invention employs transmission technologies such as sprockets and chains, gear meshing, and ball screws, and coordinates and controls them through an electrical system to achieve the functions of unlocking, locking, conveying, and transmitting power in the transfer device.

Detailed Implementation

[0016] A transfer device for unlocking, conveying, and transmitting power in a small space mainly consists of an unlocking component 3, a conveying component 5, a power transmission component 4, a limiting component 2, and a frame 1. The unlocking motor 12 drives the unlocking rod 14 to extend and engage with the shelf unlocking interface 26, completing the shelf unlocking action; simultaneously, it drives the power transmission component 4 interface to engage with the shelf power input interface, preparing for power transmission. The limiting motor 7 drives the opening of a single-sided workpiece conveying channel, ensuring smooth channel flow and end-point limiting during workpiece conveying. The conveying motor 19 drives the conveying component 5 to rotate, simultaneously transmitting power to the shelf conveying component 5, transferring the workpiece 6 from the shelf to the transfer device, completing the workpiece transfer action. This invention utilizes mature and reliable sprocket and chain, gear meshing, and ball screw transmission technologies, solving the problem of small-space layout. Gear meshing and ball screw transmission are not only safe and reliable, but also require little installation space, are simple to control, and can complete unlocking and conveying actions with high efficiency and high precision.

[0017] Based on the structural characteristics and functional requirements of the production line transportation space, and with the aim of achieving transfer in a small space, transmission technologies such as sprockets and chains, gear meshing, and ball screws are adopted to realize the functions of unlocking, locking, conveying, and transmitting power of the transfer device.

[0018] refer to Figure 1 The transfer device consists of two layers, upper and lower, with identical structural distribution. Each layer includes a limiting component 2, an unlocking component 3, a power transmission component 4, and a conveying component 5. These components are symmetrically distributed left and right and are fixed to the frame 1.

[0019] refer to Figure 2 The limiting assembly 2 consists of a limiting motor 7, a limiting block 8, a bearing seat a9, a clutch 10, and a gear belt a11. The limiting motor 7 and the bearing seat a9 are fixed on the frame 1, and the bearing seat a9 provides support for the output shaft a21. The power output by the limiting motor 7 is transmitted to the output shaft a21 through the gear belt a11. The clutch 10 enables independent control of the two limiting blocks 8 at the front and rear of the transfer device, realizing the functions of limiting and releasing the workpiece.

[0020] The unlocking assembly 3 consists of an unlocking motor 12, a gear belt b13, an unlocking rod 14, a ball screw sleeve 28, and a ball screw 22. The unlocking motor 12 and the bearing seat b18 are fixed to the frame 1, and the bearing seat b18 provides support for the ball screw 22.

[0021] The power transmission assembly 4 consists of a power transmission rod 15, a bearing housing c25, a conveyor motor 19, a sprocket and chain 20, and an output shaft b23. The conveyor motor 19 and the bearing housing c25 are fixed to the frame 1, and the bearing housing c25 provides support for the output shaft b23. The unlocking rod 14 in the unlocking assembly 3 is connected to the power transmission rod 15 in the power transmission assembly 4 via a combination plate 16.

[0022] The unlocking motor 12 outputs power to the ball screw sleeve 28 via the gear belt b13. Utilizing the transmission mechanism between the ball screw sleeve 28 and the ball screw 22, the combination plate 16 and the unlocking rod 14 and power transmission rod 15 connected thereto are pushed out, respectively connecting to the shelf unlocking interface 26 and the shelf power input interface 27, thus realizing the shelf unlocking function. (Refer to...) Figure 3 The power transmission assembly 4 is powered by the conveyor motor 19, which transmits power to the output shaft b23 via sprockets and chains. The power is then transmitted to the shelf via the power transmission rod 15 and the shelf power input interface 27, thus realizing the power transmission function.

[0023] The conveying assembly 5 consists of a conveying roller 17 and a bevel gear 24. The bevel gear 24 is fixed on the output shaft 23 in the power transmission assembly 4. The power output from the conveying motor 19 rotates the conveying roller 17, thereby realizing the function of the transfer device in conveying workpieces.

[0024] This invention provides a transfer device for unlocking, conveying, and transmitting power in a confined space. Power is transmitted via sprockets and chains, gear meshing, and rack and pinion mechanisms. This allows the motor and output mechanism to be placed vertically, thereby reducing lateral space usage and improving space utilization. Simultaneously, this transfer device solves the problem of unlocking and transmitting power in confined spaces.
