Description

Technical Field

[0001] This invention relates to the field of suspended conveyor systems, specifically a suspended conveyor system for a cabinet production line. Background Technology

[0002] Suspended conveyor systems are automated equipment that continuously transport materials or products using overhead rail-suspended vehicles (such as baskets, trolleys, etc.). The core principle is to achieve rapid handling using three-dimensional space. The system is mainly divided into two types: suspended conveyors and overhead self-propelled trolleys. The former forms a continuous conveying network through traction chains and sliding frames, while the latter uses modular cargo vehicles to achieve three-dimensional transportation.

[0003] When using a suspended conveyor structure to transfer cabinets during production, manual hanging of the cabinets is often required. Furthermore, the contact area between the suspension mechanism and the cabinet is limited, resulting in reduced operational efficiency and a risk of the cabinets falling. Therefore, this does not meet the current requirements. To address this, we propose a suspended conveyor system for cabinet production lines. Summary of the Invention

The cabinet clamps are located at one-third to one-quarter of the length of the cabinet, so that the cabinet can automatically change from a horizontal state to a vertical state by gravity after the limiting rod is released, without the need for two additional operations, simplifying the mechanical mechanism of the device and improving the operating efficiency of the suspension conveying system.

[0017] 2. This invention uses protective positioning blocks to protect the cabinet, preventing the cabinet from slipping off the inside of the cabinet clamps during rotation, thus ensuring safety during the cabinet's state transition process;

[0018] 3. This invention uses a guide docking plate and a limiting plate to support the cabinet being transported on the cabinet transmission module, and adjusts the electric telescopic rod to drive the rotating positioning plate to rotate, thereby positioning and clamping the side of the cabinet. Adjusting the position of the cabinet facilitates the cabinet suspension clamping module to accurately clamp the cabinet. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] like Figure 1 As shown, a suspended conveying system for a cabinet production line includes a suspended conveying module 1, a cabinet docking module 2, a cabinet transmission module 3, and a cabinet suspension clamping module 4. The suspended conveying module 1 includes a track structure, a chain, a carriage, a hanger, a drive structure, safety and auxiliary components, and a terminal control mechanism. The carriage is slidably connected to the track structure. The hanger is installed at the bottom of the carriage and fixedly connected to a fixed suspension rod 401. The drive structure drives the carriage to move in a closed loop on the track structure via a chain, thereby transporting the clamped cabinet.

[0028] The cabinet transmission module 3 includes a frame, multiple transmission rollers evenly spaced along the length of the frame, a power output structure, and a power transmission structure. The power transmission structure connects the transmission rollers to the power output structure, thereby enabling the transmission rollers to rotate in the same direction, thus transmitting the cabinet to the cabinet docking module 2.

[0029] like Figure 5As shown, the cabinet docking module 2 includes a fixed base 201. A guide docking plate 202 and a limiting plate 203 are fixed on the top outer surface of the fixed base 201. The guide docking plate 202 and the limiting plate 203 are on the same straight line and at the same height. Four symmetrically distributed support bars 204 are also fixed on the top outer surface of the fixed base 201. A support shaft 205 is rotatably installed between two support bars 204 on the same side of the fixed base 201. A rotating positioning plate 206 is fixed on the outside of the support shaft 205. An adjustable electric telescopic rod 207 is provided between the rotating positioning plate 206 and the fixed base 201. The adjustable electric telescopic rod 207 is fixed to the fixed base 201. The cabinet transmitted on the cabinet transmission module 3 is supported by the guide docking plate 202 and the limiting plate 203. The rotating positioning plate 206 is rotated by the adjustable electric telescopic rod 207 to position and clamp the side of the cabinet. Adjusting the position of the cabinet facilitates the cabinet hanging clamping module 4 to clamp the cabinet.

[0030] like Figures 1 to 4 and Figure 6 As shown, the cabinet suspension clamping module 4 is located below the suspension conveying module 1. The cabinet suspension clamping module 4 includes a fixed suspension rod 401, inside which a double-headed electric telescopic rod is fixed. The end of the double-headed electric telescopic rod passes through the end of the fixed suspension rod 401 and is fixed with an adjusting block 402. The bottom end of the adjusting block 402 is fixed with a lifting block 404. A cabinet clamping plate 405 is provided on the inner side of the lifting block 404. A first lifting rod 406 is fixed on one side of the lifting block 404, and a second lifting rod 407 is fixed on the other side of the lifting block 404. An adjusting rotating rod 4 is rotatably installed at the bottom end of the second lifting rod 407. 11. A limiting rod 412 is fixed between the two adjusting rotating rods 411. A rotating connecting rod 408 is rotatably installed at the bottom end of the first lifting rod 406. A connecting block 409 is provided at the end of the rotating connecting rod 408 away from the first lifting rod 406. A protective positioning block 410 is fixed on one side of the connecting block 409. The cabinet clamping plate 405 is used to clamp both sides of the cabinet, and the adjusting rotating rod 411 and the limiting rod 412 are used to press down one end of the cabinet to prevent the cabinet from rotating during the lifting process. At the same time, the protective positioning block 410 is used to protect the cabinet to prevent the cabinet from slipping off the inside of the cabinet clamping plate 405 during the rotation process.

[0031] The bottom end of the lifting block 404 has a through hole. The cabinet clamp plate 405 is fixed with a plug rod 418 facing the surface of the lifting block 404. The plug rod 418 is rotatably inserted into the inside of the hole. A torsion spring is provided between the plug rod 418 and the lifting block 404 to ensure that the cabinet clamp plate 405 can rotate synchronously with the cabinet under the action of gravity after the cabinet is freed from the pressure of the restraining rod 412. After the cabinet and the cabinet clamp plate 405 are separated, the cabinet can rotate and reset the cabinet clamp plate 405.

[0032] The bottom end of the first lifting rod 406 is provided with a docking groove 417. One end of the rotating connecting rod 408 is rotatably inserted into the inner side of the docking groove 417, and a pivot pin is provided through this end of the rotating connecting rod 408. The end of the pivot pin is rotatably inserted into the first lifting rod 406, and a torsion spring is sleeved on the outer side of the end. The elastic force of the torsion spring is greater than the sum of the weight of the rotating connecting rod 408, the connecting block 409, the protective positioning block 410, and the internal components of the rotating connecting rod 408, ensuring that the rotating connecting rod 408 can automatically reset after rotation without manual adjustment or mechanical reset.

[0033] An electromagnet 420 is fixed inside the end where the rotating connecting rod 408 connects to the connecting block 409. A movable support block 419 is fixed at the end where the connecting block 409 contacts the rotating connecting rod 408. The movable support block 419 is slidably inserted into the rotating connecting rod 408 and has a magnetic metal rod 422 fixed at its end. When the electromagnet 420 is energized, it magnetically attracts the magnetic metal rod 422. A return spring 421 is sleeved on the outside of the magnetic metal rod 422. The position of the connecting block 409 and the protective positioning block 410 is adjusted by the magnetic attraction of the magnetic metal rod 422 by the electromagnet 420, so as to realize the contact or separation of the protective positioning block 410 with the cabinet. When the protective positioning block 410 contacts the cabinet, it protects the rotating cabinet and prevents the cabinet from slipping off the inside of the cabinet clamp 405.

[0034] A limiting groove 423 is provided on one side of the movable support block 419. A limiting pin 424 is inserted into the inner side of the limiting groove 423. The limiting pin 424 passes through the side of the rotating connecting rod 408. The position of the movable support block 419 is limited by the limiting pin 424 to prevent the movable support block 419 from falling off the end of the rotating connecting rod 408 due to the elasticity of the return spring 421.

[0035] An adjusting shaft 413 is inserted through the end of the adjusting rotating rod 411 that is connected to the second lifting rod 407. The adjusting shaft 413 passes through the second lifting rod 407 and is rotatably connected to the second lifting rod 407. An adjusting gear 414 is fixed to the outer side of the end of the adjusting shaft 413 that extends through the second lifting rod 407. A transmission gear 415 is meshed with one side of the adjusting gear 414. An adjusting motor 416 is axially connected to the transmission gear 415. The adjusting motor 416 is fixed to the outer side of the second lifting rod 407. The positions of the adjusting rotating rod 411 and the limiting rod 412 are adjusted by adjusting the motor 416, the transmission gear 415, the adjusting gear 414 and the adjusting shaft 413, thereby realizing the pressing or releasing of the limiting rod 412 on the cabinet.

[0036] Working principle: When using the overhead conveyor system to transport cabinets in production, the cabinet is first transferred to the cabinet docking module 2 by the cabinet transfer module 3. The cabinet moves to the surface of the fixed seat 201 and the limiting plate 203 through the guide docking plate 202, and is restricted in its movement position by the limiting plate 203. After the cabinet is separated from the cabinet transfer module 3, the two adjusting electric telescopic rods 207 are simultaneously energized and their ends extend. The ends of the adjusting electric telescopic rods 207 push the bottom end of the rotating positioning plate 206, so that the top of the rotating positioning plate 206 rotates upward around the axis of the supporting rotating shaft 205 until the supporting rotating shaft 205 contacts the side of the cabinet. The rotating supporting rotating shaft 205 clamps the cabinet from the side, so that the center line of the cabinet is located between the two cabinet clamping plates 405.

[0037] Subsequently, the double-headed electric telescopic rod inside the fixed suspension rod 401 is energized and its end extends, causing the adjusting block 402 to separate from the fixed suspension rod 401 until the position of the cabinet clamping plate 405 exceeds the position of the cabinet side. At this time, the lifting hydraulic rod 403 drives the lifting block 404, the cabinet clamping plate 405, the first lifting rod 406 and the second lifting rod 407 to move down until the limiting rod 412 contacts the upper surface of the cabinet. Then, the double-headed electric telescopic rod is energized and its end retracts until the cabinet clamping plate 405 is engaged with the cabinet side. Subsequently, the electromagnet 420 is energized and magnetically attracts the magnetic metal rod 422, causing the connecting block 409 to move closer to the end of the rotating connecting rod 408, and the protective positioning block 410 to contact the end corner of the cabinet.

[0038] At this point, the adjusting shaft 413 is energized and drives the lifting block 404 to move upward. Simultaneously, the cabinet clamping plate 405 and the protective positioning block 410 move the clamped cabinet upward until its height exceeds the top of the rotating positioning plate 206. The suspended conveying module 1 then transports the clamped cabinet. After the cabinet moves away from above the cabinet docking module 2, the adjusting motor 416 is energized and drives the transmission gear 415 to rotate. The transmission gear 415, through the adjusting gear 414, drives the adjusting shaft 413 and the adjusting rotating rod 411 to rotate. At this time, the adjusting rotating rod 411 drives the adjusting block... 402 rotates upward until the adjusting rotating rod 411 enters the inner side of the second lifting rod 407. Since the cabinet clamping plate 405 is engaged at one-third to one-quarter of the length of the cabinet, the weight of the two ends of the cabinet is unbalanced and one end of the cabinet loses the pressure of the limiting rod 412. At this time, the cabinet drives the protective positioning block 410 and the rotating connecting rod 408 to rotate downward. At the same time, the cabinet clamping plate 405 changes from a horizontal state to a vertical state, realizing the automatic clamping, locking and state transportation state conversion of the cabinet, saving the time of hanging the cabinet and improving the operation efficiency and running efficiency of the hanging conveyor system.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
