Description

Technical Field

[0001] This invention belongs to the technical field of mechanical automation and relates to an elevator-type transfer device for horizontal bidirectional transmission and vertical lifting and transfer in narrow spaces. Background Technology

[0002] In a certain conveyor production line, the cargo boxes are densely packed. To ensure the required quantity of cargo boxes, the transfer space is very limited, and cargo box transfer can only be completed in a narrow aisle between the two side shelves. The weight of the workpieces being transferred is as high as 400 kg, and they are stacked side by side on the shelves. Therefore, inventing an elevator-type transfer device is a key challenge in cargo box transfer within the conveyor production line.

[0003] This invention takes into account the limited transfer space and combines horizontal conveying and vertical lifting functions to realize the transfer function of upper and lower cargo boxes in narrow spaces, reduce the number of motors, and improve the reliability of the transfer device. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal bidirectional conveying and vertical lifting transfer device for cargo boxes in narrow spaces. The technical problem it addresses is that the workpieces being transferred on production lines are heavy and large, and the transfer channels are narrow, which current transfer devices on the market cannot meet. This invention designs an elevator-type transfer device. A horizontal drive motor is connected via gears, chains, etc., transmitting power to rollers on both sides, reducing the number of motors and thus improving reliability. The space in front of and behind the rollers is not enclosed, enabling horizontal bidirectional conveying of cargo boxes. The lifting motor is placed vertically, reducing lateral space usage and improving space utilization. Power is transmitted via a lead screw to achieve the lifting function of the cargo box.

[0005] The technical solution of this invention, based on the transfer space, employs transmission technologies such as sprockets and chains, gear meshing, lead screws, and rollers, and coordinates and controls them through an electrical system to achieve the functions of horizontal linear movement of the transfer device, bidirectional transport of cargo boxes, and lifting and transferring of cargo boxes. The mechanism of this technical solution mainly consists of a track assembly, a main frame, a vertical lifting assembly, a horizontal conveying assembly, a drive assembly, and a high-position limit assembly.

[0006] The drive motor moves the gear along the rack, thus driving the transfer device to move horizontally along the track. The horizontal conveyor assembly's drive motor drives the reducer, which in turn drives the transmission shaft via a gear belt. Power is transmitted to the rollers on both sides via a reversing shaft and bevel gears, and then to the remaining rollers via a chain for synchronous movement. The drive motor's forward and reverse rotation drives the rollers to rotate in both directions, achieving bidirectional horizontal movement of the cargo box. When the lifting motor is working, the lead screw rotates, causing the lifting frame connected by the lead sleeve to slide up and down along the guide rail, achieving vertical lifting of the cargo box. The limit motor drives the gear on the rack, which in turn causes the limit plate to extend or retract along the track. When the main frame is in the lower position, the limit plate retracts, reserving a lifting channel for the main frame to rise; when the main frame is in the upper position, the limit plate extends, providing mechanical restraint for the main frame and improving the safety and reliability of the transfer device.

[0007] According to one aspect of this application, an elevator-type transfer device is provided, comprising a track assembly 1, a main frame 2, a vertical lifting assembly 3, a horizontal conveying assembly 4, a drive assembly 5, and a high-position limiting assembly 6.

[0008] The track assembly 1 consists of a lower track 101, an upper track 102, and a slider 103, providing guidance and support for the overall movement of the elevator-type transfer device;

[0009] The upper track 102 has two sections, which are fixed to the roof;

[0010] The lower track 101 has two sections, which are fixed to the ground;

[0011] The slider 103 is fixed to the inside of the main frame 2 by bolts. Four sliders are provided on the upper surface of the inside of the main frame 2 for use with the upper rail 102, and four sliders are provided on the lower surface of the inside of the main frame 2 for use with the lower rail 101.

[0012] The main frame 2 is welded from thin steel plates, providing external protection and interfaces for the elevator-type transfer device;

[0013] The main frame 2 is provided with a lead screw interface 201, a high-position limit component interface 202, and a drive component interface 203.

[0014] The vertical lifting assembly consists of three parts: a lifting motor 301, a reducer 302, a lead screw 303, a lead sleeve 304, a bearing 305, a lifting frame 306, a guide rail 307, and a slider 308.

[0015] There are two sets of vertical lifting components 3, which are symmetrically installed on the left and right sides of the main frame 2.

[0016] In the vertical lifting assembly on the left, the lead screw 303 passes through the bearing 305 and is fixed in the lead screw interface 201 on the side of the main frame 2. The lead sleeve 304 passes through the lead screw 303. The lifting frame 306 passes through the lead screw interface 201 and is fixed to the lead sleeve 304 by bolts. The lifting motor 301 is connected to the reducer 302 and is connected to the lead screw 303.

[0017] The vertical lifting assembly on the right is the same as that on the left;

[0018] When the lifting motor 301 is working, the lead screw 303 rotates, causing the lifting frame 306 connected by the lead sleeve 304 to slide up and down along the guide rail 307, thereby realizing the vertical lifting function of the cargo box 7.

[0019] The horizontal conveying assembly 4 consists of a drive motor 401, a reducer 402, a gear belt 403, a transmission shaft 404, a chain 405, a reversing shaft 406, a bevel gear 407, rollers 408 and 409, and a chain 410.

[0020] The horizontal conveying assembly 4 is installed inside the lifting frame 306. The drive motor 401 drives the reducer 402 to drive the transmission shaft 404 to rotate through the gear belt 403. The power is transmitted to the roller 409 through the reversing shaft 406 and the bevel gear 407. The roller 409 drives the roller 408 to achieve synchronous movement through the chain 410. The horizontal movement of the cargo box is completed by the rotation of the rollers 408 and 409.

[0021] The drive assembly 5 consists of a drive motor 501, a reducer 502, a gear 503, and a rack 504;

[0022] The drive motor 501 and reducer 502 are installed on the right side of the main frame 2, and the rack 504 is fixed below the main frame 2 and placed parallel to the lower track 101.

[0023] The drive motor 501 drives the gear 503 to move along the rack 504, thereby driving the elevator-type transfer device to move as a whole along the lower track 101 and the upper track 102.

[0024] The high-position limiting component 6 consists of a limiting motor 601, a track 602, a slider 603, a gear 604, a rack 605, and a limiting plate 606.

[0025] The limiting motor 601 and the track 602 are fixed at the high and low limiting component interface 202 at the middle position on the left side of the main frame 2.

[0026] The slider 603 and rack 605 are fixed on the limiting plate 606;

[0027] The limiting motor 601 drives the gear 604 to move on the rack 605, thereby causing the limiting plate 606 to extend or retract along the track direction.

[0028] When the main frame 2 is in the lower position, the limiting plate 606 retracts to reserve a lifting channel for the main frame 2 to rise. When the main frame 2 is in the upper position, the limiting plate 606 extends to provide mechanical limiting for the main frame 2, thereby improving the safety and reliability of the elevator-type transfer device.

[0029] This invention utilizes mature and reliable transmission technologies such as sprockets and chains, gear meshing, lead screws, and rollers, solving the problem of small space layout. Gear meshing and lead screw transmission are not only safe and reliable, but also require little installation space, are simple to control, and can complete translation, lifting, and bidirectional conveying actions with high efficiency and high precision.

[0030] The effects and benefits of this invention: This invention is designed primarily based on actual usable space and functional characteristics, employing mature market technologies, and featuring a compact overall mechanical structure. The overall structure is safe and reliable, with high space utilization, high transportation efficiency, reduced production and maintenance costs, and enhanced reliability, maintainability, and safety of the transfer device.
