Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to an accumulating roller conveyor line. Background Technology

[0002] Accumulating roller conveyors enable continuous material transport, smoothly moving materials from one workstation to another. They also have an accumulation function, allowing materials to be temporarily stored and accumulated on the conveyor line when downstream processes malfunction or when transport is not immediately required. This prevents production line blockages, acts as a buffer, and regulates production rhythm, improving the flexibility and reliability of the production system. They are widely used in logistics, warehousing, and various manufacturing industries.

[0003] As disclosed in patent announcement number CN222158595U, an accumulating roller conveyor line includes a frame. Several drive rollers are arranged side-by-side on one side of the frame, and a first active roller is arranged on the other side of the frame. First driven rollers are respectively arranged on both sides of the first active roller. This invention utilizes a third motor, a movable frame, a clamping rod, a threaded rod, and a second single-groove pulley in cooperation. When the first item is fed onto the drive roller, the first driven roller is stopped again. The first driven roller is restarted only after the item on the drive roller has moved to a designated position. This reciprocating motion allows for adjustment of the spacing between items without stopping the machine, preventing workers from finding items too close together and causing inconvenience when picking them up.

[0004] However, during the use of this utility model, because the upstream products are still continuously being conveyed to the accumulation area, and the accumulation area has no shielding measures, the products are easily pushed to the downstream conveyor line, and the products are prone to piling up and falling off the conveyor line, thus increasing the amount of manual work. To this end, we have proposed an accumulation roller conveyor line, which solves the problems of poor product accumulation effect and easy product falling off the conveyor line of this utility model, and improves the practical effect of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide an accumulating roller conveyor line to solve the problems mentioned in the background art.

An electric telescopic rod 203 is hinged to the side plate 201 near the accumulation plate 202, and the top of the electric telescopic rod 203 is hinged to the accumulation plate 202. A through hole is opened at one end of the accumulation plate 202 near the side plate 201, and a connecting shaft 204 passes through the through hole. A limit cap 205 is fixedly installed at the top of the connecting shaft 204. A mounting column 206 is fixedly installed at the top of the mounting platform 200, and a mounting groove 207 is opened inside the mounting column 206. The bottom end of the connecting shaft 204 is fixedly installed inside the mounting groove 207. The accumulation plate 202 is rotatably connected to the connecting shaft 204. A PLC control panel 208 is fixedly installed on the side away from the accumulation plate 202. The PLC control panel 208 is electrically connected to the electric telescopic rod 203 through a microcontroller. Through the accumulation temporary storage mechanism set on one side of the roller conveyor body 100, when the roller conveyor needs to temporarily store products on the conveyor line during product conveying, the PLC control panel 208 sends a start / stop signal to the microcontroller. The microcontroller can set the start / stop interval time of the electric telescopic rod 203 through the PLC empty box panel, thereby adjusting the production rhythm. The microcontroller controls the extension of the electric telescopic rod 203, thereby driving the accumulation plate 202 to rotate along the connecting shaft 204 to the set position, realizing the effect of stopping the products on the roller conveyor line and avoiding the production rhythm disorder caused by product congestion downstream of the conveyor line.

[0023] In this embodiment, preferably, the anti-fall mechanism includes a heightening baffle 300, which is slidably installed on the top of the roller conveyor body 100. Sliding grooves 301 are provided on both sides of the top of the roller conveyor body 100. A sliding block 302 adapted to the sliding groove 301 is provided at the bottom of the heightening baffle 300. A threaded hole 303 is provided on one side of the top of the roller conveyor body 100. A limiting hole 304 corresponding to the threaded hole 303 is provided on the heightening baffle 304.

Through the heightening baffle 300, sliding groove 301, and sliding block 302 provided by the anti-fall mechanism, when the roller conveyor line is in operation and transporting large items, the heightening baffle 300 can be slidably installed on both sides of the conveyor line and fixed with the limiting bolts 305, achieving a heightening effect on both sides of the conveyor line and effectively reducing the probability of products falling off the conveyor line.

[0024] In this embodiment, preferably, the auxiliary moving mechanism includes a movable wheel 400 and a threaded support foot 401. The threaded support foot 401 is located near the movable wheel 400. A support leg 101 is fixedly installed at the bottom of the roller conveyor body 100.

A U-shaped plate 103 is fixedly installed on one side of the load-bearing plate 102. The U-shaped plate 103 is threadedly connected to the threaded support foot 401. The conveyor line is moved to the working area by the movable wheel 400 of the auxiliary moving mechanism. Then, by rotating the threaded rod movably installed on the threaded support foot 401, the support foot connected to the bottom of the threaded rod is moved down to the ground, and the center of gravity of the conveyor line is transferred from the movable wheel 400 to the threaded support foot 401. This achieves the effect of fixing the working position of the roller conveyor body 100 and prevents the conveyor line from slipping during use.

[0025] In this embodiment, when an accumulating roller conveyor line is in use, the conveyor line is first moved to the working area by the movable wheel 400 of the auxiliary moving mechanism. Then, by rotating the threaded rod movably installed on the threaded support foot 401, the support foot connected to the bottom of the threaded rod is moved down to the ground, and the center of gravity of the conveyor line is transferred from the movable wheel 400 to the threaded support foot 401, thereby achieving the effect of fixing the working position of the roller conveyor body 100 and preventing the conveyor line from slipping during use. By using an accumulation and temporary storage mechanism on one side of the roller conveyor body 100, when the roller conveyor needs to temporarily store products on the conveyor line during product transport, a start / stop signal is sent to the microcontroller via the PLC control panel 208. The microcontroller can set the start / stop interval of the electric telescopic rod 203 via the PLC control panel, thereby adjusting the production rhythm. The microcontroller controls the extension of the electric telescopic rod 203, which drives the accumulation plate 202 to rotate along the connecting shaft 204 to a set position, achieving the effect of stopping the products on the roller conveyor line and avoiding production rhythm disruptions caused by product congestion downstream. The anti-fall mechanism includes a heightening baffle 300, a sliding groove 301, and a sliding block 302. During operation, when transporting large items, the heightening baffle 300 can be slidably installed on both sides of the conveyor line and fixed with limit bolts 305, achieving a heightening effect on both sides of the conveyor line. This effectively reduces the probability of products falling off the conveyor line and improves the conveying efficiency.
