200~2000KG Load Accumulating Roller Free Flow Chain Conveyor Assembly

Description

Free flow conveyor is also namely accumulating roller chain conveyor or double speed chain conveyor. Similar to normal chain conveyor, it’s also a conveyor machine that uses chain as traction part and product. But there is also difference. The conveying principle is to use the speed increasing function of the double-speed chain. Therefore, the workpiece pallet which supports the products can run quickly. Free flow chain conveyor is mainly used in assembly production lines. It can realize the complementarity of each work station.

What is free flow conveyor chain?

Different from normal chain conveyor, it uses the accumulating roller chain. So what is the difference between them? How does the free flow conveyor chain work?

Above all, the double-speed chain composes of large-diameter rollers, small-diameter rollers and joint chain links. The small rollers run on the guide rail, and big rollers support the workpiece pallets. When we drag the entire chain to move, it is actually small rollers moving on the guide rail. On the other hand, when the whole chain moves, the large rollers and the small rollers move synchronously. In other words, when the small roller runs for one circle, the large roller also runs for one circle. However, due to the difference in diameter, their actual movement distance in the horizontal direction is different. The running distance of the big roller is much greater than that of the small roller.

For example, the free flow conveyor chain runs at the speed of V1. Then the turnover speed of the small roller is V1. At this time, the turnover speed of the big roller is (R/r)*V1. Therefore, the running speed (V) of the workpiece pallet is the sum of the large roller speed and the chain speed. That is, V=(R/r)*V1+V1=(R/r+1)*V1. If the ratio of the radius of the big roller to the small roller is 1.5:1, the speed of the conveyor pallet is V=(1.5+1)*V1=2.5*V1.

The running speed of the product is faster than that of the accumulating roller chain. Therefore, due to the special structure of the double-speed chain, it produces the speed-increasing effect. Of course, due to the chain structure, the speed increase of the accumulating roller chain is limited. The usual speed-up effect of free flow conveyor is V=(2~3)*V1. Common specifications are 2.5 times speed conveyor chain and 3 times speed conveyor chain.

Why need accumulating roller chain conveyor?

Traditional manual assembly line requires workers on both sides. For example, there is an air conditioning assembly line. Twist the screws in the first station. The second station installs other parts. The third station is labeled. The efficiency of manual operation is not always very high. To improve production efficiency, we began to use free flow chain conveyor.

The accumulating roller chain can quickly move the pallet from one process to the next. In the double-speed chain conveyor assembly line, each process is operated by robots. In order to facilitate the operation of the robot, it adds blocking mechanisms.

Technical Parameters of Double Speed Chain Conveyor

The Characteristic of Accumulating Roller Chain Conveyor

1. First of all, it uses a special aluminum profile as the guide rail. So it makes the double speed chain conveyor have very good stability and durability during the conveying process. Therefore, it’s suitable for continuous mass production of products.

2. Secondly, it can move the workpiece for long distance. And speed can be fast. At the same time, it can realize accumulation type conveying to prevent material backlog.

3. Thirdly, the conveying capacity is large. Besides, free flow chain conveyor can carry a large load. Loads from 200KG to 2000KG are applicable.

4. It can meet the needs of a variety of production processes, such as glue dispensing, large screws, welding, etc.

5. In addition, accumulating roller chain conveyor can achieve a variety of test requirements, such as CCD vision, photoelectric detection, resistance detection, withstand voltage detection, product function detection, etc.

6. Free flow conveyor can be applicable to various types of similar products. Moreover, if customers need to increase product types, they can quickly upgrade and transform.

7. The double-speed chain assembly conveyor is flexible. For example, when we need to improve production efficiency, we can increase the number of pallets and work stations. vice versa. On the other hand, it can also design complex product flow. For example, we can add horizontal traversing and turning devices to realize a horizontal circular assembly line. Or to achieve a more complex shape of the assembly line.

8. Finally, it can realize intelligent manufacturing functions. The running data, inspection data and production data of the entire production line can be saved and summarized. So it’s convenient to read online or online.

How to choose free flow chain conveyor?

When you need to customize the free flow chain assembly conveyor, please confirm the below details:

1. Firstly, it needs to inform the size and weight of the product. Because this will affect the selection of tooling board and motor power.

2. Secondly, clarify the shape and layout of the accumulating roller chain conveyor. Is it a straight line, a horizontal loop or a vertical loop?

3. Thirdly, determine the size of the double-speed chain conveyor. The longest can be 30-40 meters. The width is generally 250~900mm (customizable). Additionally, the height is generally 500~1200mm.

4. Fourthly, confirm the operating speed of the free flow chain conveyor. Generally, the maximum speed is 20m/min.

5. Fifthly, determine the type of double-speed chain. The speed is divided into 2.5 times and 3 times. The large rollers can be stainless steel and engineering plastics.

6. Material selection: there are a variety of materials for workpiece pallets to choose from, such as aluminum, steel, engineering plastic, wood, etc. The frame materials are generally aluminum profiles and painted steel.

7. In addition, it is best to inform your process flow. At the same time, inform whether there are additional functions onto free flow conveyor, such as product testing.

8. Finally, confirm the power supply: single-phase 220V / three-phase 380V 50Hz or others.

How to replace free flow conveyor chain?

In fact, the installation of accumulating rolller chain conveyor is other chain conveyors. When you need to replace the free flow conveyor chain, remove the old chain firstly. Then, place the chain on the chain shaft in order to avoid chain damage. And guide the chain trough the lower part of the drive unit. Immediately afterwards, bypass driven sprocket, the drive end and the drive sprocket in turn. Finally connect the double speed conveyor chain.

Similar to belt conveyor, free flow conveyor also needs to tighten the chain. Otherwise it will influence the load-bearing capacity of the conveyor assembly line.

Kind note: this free flow chain conveyor has self-tensioning device. It needs often observe the length of Y. Besides, it must ensure that 35≤Y≤55.

How to maintain accumulating roller chain conveyor?

Before starting the free flow chain conveyor daily, we should check whether there are fragments in the chain. Otherwise, it will damage the chain. In addition, clean the assembly conveyor line each week. And often check if the double speed conveyor chain is loose. At the same time, check whether the chain needs lubrication.

Chain lubrication

Before starting the free flow conveyor for the first time, you must lubricate chain. How to lubricate the chain? Drage the whole chain. Lubricate the chain with an amount of about 2~3ml/m. Recommend 15W40 Shell oil.

In addition, as long as the equipment is down for more than 6 months, you need re-lubricate it. Before lubricating, remove excess grease, oil stains or other impurities on the accumulating roller chain. At the same time, check whether the chain is worn or stretched. Lubrication method and oil volume are the same as above.

During normal use of the assembly conveyor, it needs re-lubricate the chain every 1000 hours. Lubricate a small amount each time-about 2ml/m. In addition, if the operating environment has high humidity, we should shorten the interval time between each lubrication according to the actual situation.

Of course, we can customize the self-lubrication system. It can optimally and uniformly lubricate the free flow conveyor chain during equipment operation.

When using the free flow conveyor, if there is an emergency, press the red emergency stop switch immediately. Then turn off the power and start the solution.
