Description

Technical Field

[0001] The invention belongs to the technical field of production and manufacturing, and specifically relates to a heavy-load RGV trolley. Background Art

[0002] In today's diversified manufacturing field, accurate and efficient material handling is of vital importance. Traditional ordinary transport carts have single functions and can only adapt to materials of fixed specifications, which greatly limits their application scenarios. This innovative transport cart stands out. Its material guiding link abandons the easily damaged cylinder telescopic structure and adopts a motor and chain collaborative drive mode. The chain has inherent flexibility. When encountering accidental collision with materials, it can effectively buffer the unloading force, greatly reduce the risk of component damage, and ensure the stability and durability of the equipment. In contrast, the common cylinder guides on the market, once hit, are not only easily damaged themselves, but also have high maintenance costs, and will frequently stop and affect the production rhythm. Moreover, traditional solutions often require the trolley to be equipped with complicated accessories such as air pumps, which undoubtedly makes the trolley structure bloated and the volume expanded, and its movement is restricted in the narrow production space, which brings many inconveniences to customers.

[0003] When facing the handling of large-sized materials, the disadvantages of the ordinary multi-cylinder controlled guidance are fully revealed. Due to the long guiding distance, it is difficult to coordinate multiple cylinders synchronously, and the advancement speed is often inconsistent, which leads to the guidance jamming and the operation of the equipment is blocked. However, this new trolley relies on the advanced single-motor driven chain technology to ensure smooth and unobstructed guidance throughout the process. Considering the high-frequency demand for material reversing in the customer's production line, the trolley has a breakthrough built-in reversing mechanism, which does not require the customer to purchase and install a reversing device separately. The reversing mechanism relies on the exquisite coordination of the motor and the connecting rod, and is precise and powerful when operating. It automatically self-locks when in place, eliminating the reversing displacement deviation and ensuring that the material is accurately connected to the subsequent process. Compared with the conventional cylinder locking reversing, the motor-driven method greatly simplifies the space occupation, reduces the dependence on the gas source, and reduces energy consumption and equipment complexity.

A bearing seat 405 is fixedly sleeved and installed at three positions: left, middle and right. A fixed sprocket seat 409 is fixedly installed on the top of the material conveying component 3, and the fixed sprocket seat 409 corresponds to the left, middle and right bearing seats 405. The outer surface of the bearing seat 405 and the outer surface of the fixed sprocket seat 409 are fixedly sleeved with a second sprocket 406, and the connecting shaft 403 passes through the three bearing seats 405 on the left, middle and right, and the second sprocket 406 on the inner side is fixedly sleeved therewith. The two second sprockets 406 are connected through a chain 407. A chain pull rod 408 is fixedly installed on the upper outer surface of the chain 407, a guide member 412 is fixedly installed on the top of the chain pull rod 408, and the three chain pull rods 408 are evenly fixedly connected to the guide member 412.

[0030] When the staff starts the guide switching bidirectional motor 402 through the external controller, when the guide switching bidirectional motor 402 is started, the bidirectional output shaft will start to rotate, and then drive the connecting shaft 403 to start rotating. When the connecting shaft 403 starts to rotate, it will drive the second sprocket 406 inside the three left and right middle bearing seats 405 to start rotating, and the fixed sprocket seat 409 contains a rotatably installed roller. Then, through the second sprocket 406 inside the three left and right middle bearing seats 405, the three corresponding chains 407 drive the second sprocket 406 inside the fixed sprocket seat 409 to start rotating. When the chain 407 starts to rotate, it will drive the chain pull rod 408 to start moving, thereby driving the guide member 412 to move on the outer surface of the material conveying component 3, so that the guide member 412 moves and adjusts the distance between it and the fixed member 413 to meet the passage of different material product sizes.

[0031] The left, middle, and right bearing seats 405 drive the rotation of the bearing seat inside the fixed sprocket seat 409 through three corresponding chains 407.

The two first conveying rollers 306 and the second conveying roller 307 are connected by a transmission chain 302.

[0039] Start the conveying motor 303 through an external controller. When the conveying motor 303 starts, it will cause the output shaft to drive the first sprocket 305 at the end to start rotating. When the first sprocket 305 starts to rotate, it will drive the first sprockets 305 sleeved on the outer surfaces of the first conveying roller 306 and the second conveying roller 307 through the transmission belt 308.

[0048] Working principle and usage process:

[0049] When the staff starts the guide switching two-way motor 402 through an external controller, when the guide switching two-way motor 402 starts, the two-way output shaft will start to rotate, and then drive the connecting shaft 403 to start rotating. When the connecting shaft 403 starts to rotate, it will drive the second sprockets 406 inside the left, middle, and right bearing seats 405 to start rotating. And the fixed sprocket seat 409 internally contains a rotatably installed roller. Then, through the second sprockets 406 inside the left, middle, and right bearing seats 405, the second sprockets 406 inside the three corresponding fixed sprocket seats 409 are driven to rotate. When the chain 407 starts to rotate, it will drive the chain pull rod 408 to start moving, thereby driving the guide member 412 to move on the outer surface of the material conveying assembly 3, so that the movement of the guide member 412 adjusts the distance from the fixing member 413 to meet the passage of different material product sizes.

[0050] When the staff starts the motor 201 through an external controller, then the motor 201 will drive the output shaft end to drive the gear 202 to start rotating. When the gear 202 starts to rotate, it will drive the slewing bearing 203 meshed with it to start rotating. And since the material conveying assembly 3 is fixedly installed on the slewing bearing 203, the material conveying assembly 3 rotates together to realize the steering of the material. As shown in Figure 10 The rotating material conveying assembly 3 is driven by the material reversing assembly 2 to be reversed to the docking station A and the docking station B.

[0051] Start the locking motor 501 through an external controller. Then, the output shaft of the locking motor 501 will drive the first connecting rod 502 to start rotating. Then, the first connecting rod 502 will drive the second connecting rod 504 to rotate. Then, when the second connecting rod 504 rotates, it will drive the guide post 505 and the moving wedge block 510 to move up and down. The electrical limit is composed of the induction plate 509, proximity switch 508, and electrical installation plate 507 induction plate. When the moving wedge block 510 fits with the fixed wedge block 511, the material conveying assembly 3 will be locked and stopped.
