Description

Technical Field

[0001] This utility model belongs to the field of assembly line technology, and specifically relates to an automatic feeding system for an assembly line with adjustable spacing. Background Technology

[0002] In modern industrial production, assembly line feeding systems play a crucial role, as their efficient and continuous operation greatly improves production efficiency. However, existing assembly line feeding systems generally suffer from a significant design flaw: the fixed spacing between the baffles. This fixed spacing design performs well when dealing with products of a single size or specification, but its applicability is greatly reduced when switching to products of different sizes.

[0003] Specifically, when the size of products to be processed on the production line changes, such as from large to small, the original fixed-space baffles often cannot effectively adapt to the new product size. Small-sized products are prone to dispersion during transport due to excessive spacing, which not only increases the risk of product damage but may also lead to uneven material supply, affecting subsequent production processes and product quality. Conversely, if the product size increases, the fixed spacing may restrict the smooth passage of products, causing jams or blockages, which also negatively impacts production efficiency.

[0004] In conclusion, there is a certain market demand for an automated feeding system for production lines with adjustable spacing. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides an automatic feeding system for production lines with adjustable spacing to solve the aforementioned problems.

[0006] This utility model discloses an automatic feeding system for an adjustable-spacing assembly line, comprising a conveyor frame, on which are arranged a plurality of rotating rollers and adjusting rollers. An adjusting roller is located at each end of the conveyor frame, and adjusting rollers are interspersed among the rotating rollers. Each adjusting roller is a hollow roller, and each end has a plurality of grooves arranged in a rotating array around its axis. A baffle sprocket is slidably mounted in each groove of the adjusting roller, and a baffle chain is fitted onto it, connecting all the baffle sprockets at that end. One end of the adjusting roller is equipped with a lead screw motor and a conductive slip ring. The lead screw motor is connected to a bidirectional lead screw that passes through the adjusting roller. Two lead screw seats are symmetrically arranged on the bidirectional lead screw, and each lead screw seat is connected to a baffle sprocket. A distance sensor is installed on the conveyor frame, and the detection end of the distance sensor corresponds to the outer side of the adjacent baffle chain. One end of the conveyor frame is equipped with a drive mechanism for driving the rotation of one adjusting roller.

[0007] Furthermore, the driving mechanism includes a drive motor, a drive wheel is provided on the output shaft of the drive motor, a driven wheel is provided on the transmission shaft of one of the adjusting rollers, and a transmission belt is provided between the drive wheel and the driven wheel.

[0018] To better understand this utility model, the following is in conjunction with... Figures 1 to 4 The embodiments of this utility model will be explained in detail below.

[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0020] This invention discloses an automatic feeding system for an assembly line with adjustable spacing, comprising a conveyor frame 1 made of robust metal material to ensure long-term stability and durability. The conveyor frame 1 is equipped with several rotating rollers 2 and adjusting rollers 3. The rotating rollers 2 support and transport products, while the adjusting rollers 3 adjust the spacing between adjacent baffles. In this invention, an adjusting roller 3 is provided at both ends of the conveyor frame 1, and adjusting rollers 3 are also interspersed among the rotating rollers 2; for example, an adjusting roller 3 is provided every two rotating rollers 2, or every three rotating rollers 2. This design allows the adjusting rollers 3 to be flexibly distributed at different positions on the conveyor frame 1 to adjust the spacing as needed.

[0021] The adjusting roller 3 is a hollow roller, with grooves 4 arranged in a rotating array around its axis at both ends. These grooves 4 are used to accommodate and slide baffle sprockets 5. A baffle sprocket 5 is slidably disposed in each groove 4 at each end of each adjusting roller 3, and a baffle chain 6 (prior art) is fitted on it to connect all the baffle sprockets 5 at that end. In this way, when the adjusting roller 3 rotates, the baffle sprockets 5 and the baffle chain 6 will move accordingly, thereby changing the spacing between adjacent baffle chains 6.

[0022] To achieve automatic spacing adjustment, a lead screw motor 7 and a conductive slip ring 8 are installed at one end of the adjusting roller 3. The lead screw motor 7 is fixed to the end face of the adjusting roller 3 and rotates with it. The conductive slip ring 8 prevents the lead screw motor 7's wiring from becoming entangled. The lead screw motor 7 is connected to a bidirectional lead screw 9 that passes through the adjusting roller 3. Two lead screw seats 10 are symmetrically arranged on the bidirectional lead screw 9, and each of these two lead screw seats 10 is connected to a baffle sprocket 5. When the lead screw motor 7 is working, the bidirectional lead screw 9 drives the two lead screw seats 10 to move within the slide groove 4, thereby driving the baffle sprocket 5 and the baffle chain 6 to move, thus achieving spacing adjustment.

[0023] In addition, a distance sensor 11 is installed on the conveyor frame 1. The detection end of the distance sensor 11 corresponds to the outer side of the adjacent baffle chain 6, and is used to monitor the distance between adjacent baffle chains 6. When changing products, the distance sensor 11 will send a signal to control the lead screw motor 7 to work and adjust the distance to a suitable range.

[0024] To drive the adjustment roller 3 to rotate, a drive mechanism 12 is provided at one end of the conveyor frame 1. The drive mechanism 12 includes a drive motor, and a drive wheel is provided on the output shaft of the drive motor. A driven wheel is provided on the transmission shaft 16 of one of the adjustment rollers 3, and a transmission belt is provided between the drive wheel and the driven wheel. When the drive motor is working, it drives the drive wheel to rotate, which in turn drives the driven wheel and the adjustment roller 3 to rotate through the transmission belt. End caps 14 are provided at both ends of the adjustment roller 3. One end cap 14 is provided with a lead screw motor 7 and a bearing 15 that cooperates with a bidirectional lead screw 9, and the other end cap 14 is provided with a transmission shaft 16. The transmission sprocket 13 is provided on the transmission shaft 16.

[0025] In addition, to achieve synchronous rotation of multiple rotating rollers 2 and adjusting rollers 3, the present invention also provides a transmission sprocket 13 at one end of each rotating roller 2 and adjusting roller 3, and a transmission chain is fitted onto all the transmission sprockets 13 in series. In this way, when one rotating roller 2 or adjusting roller 3 rotates, it will drive the other rotating rollers 2 and adjusting rollers 3 to rotate synchronously through the transmission chain.

[0026] To facilitate the inspection and installation of components such as the baffle sprocket 5 and the lead screw seat 10 inside the adjusting roller 3, end caps 14 are provided at both ends of the adjusting roller 3 and are connected by bolts. One end cap 14 is equipped with a lead screw motor 7 and a bearing 15 that cooperates with the bidirectional lead screw 9, while the other end cap 14 is equipped with a drive shaft 16. The aforementioned drive sprocket 13 and driven wheel are both mounted on the drive shaft 16.

[0027] To enhance the stability and anti-slip performance of the conveying mechanism, the present invention also provides annular grooves 17 in the middle sections of both the rotating roller 2 and the adjusting roller 3, and a support belt 18 adapted to the annular grooves 17 is fitted onto the rotating roller 2 and the adjusting roller 3. The support belt 18 fits tightly within the annular grooves 17, providing stable support for the product and preventing it from entering the gaps between the rollers. Simultaneously, anti-slip textures are also provided within the annular grooves 17 to further enhance the anti-slip performance.

[0028] The usage and principle of this utility model:

[0029] First, based on the product's size requirements, the distance between adjacent baffles is adjusted to a suitable range using the distance sensor 11 and the lead screw motor 7. Then, the drive motor is started, rotating the adjusting roller 3 and the rotating roller 2, placing the product on the conveyor frame 1. The rotating roller 2 and adjusting roller 3 support and transport the product to the next process. During transport, the distance sensor 11 helps technicians monitor the distance between adjacent baffle chains 6 and adjust it according to product needs, ensuring stable transport after product replacement. Simultaneously, the support belt 18 provides stable support for the product, further improving transport stability and efficiency.
