Double speed chain conveyor line / Automated Production Lines

 Double speed chain conveyor line/Automated Production Lines

Definition : Multiplier Chain Conveyor Line is a kind of automatic conveyor equipment with multiplier chain as the core driving part, which is widely used in the assembly, testing, packaging and other production processes in the industries of electronics, home appliances, auto parts and so on. Its core feature is to realize precise conveying, staging and beat control of materials (or workpieces) through the cooperation of chain and workpiece plate, which is especially suitable for continuous or intermittent operation in the automated production line.

Product application field

The characteristics of multiplier chain conveyor line make it especially suitable for automated assembly lines. Typical applications include: 

Electronics industry:

parts assembly, testing and packaging lines for cell phones, computers and other products.

Home appliance industry:

shell assembly of TV sets, washing machines, parts installation line.

Automotive parts industry:

 automotive instrumentation, wiring harness, small assembly assembly line.

Medical device industry:

assembly and testing lines for small medical devices.

Its advantages are especially prominent in the “need for frequent start-stop, accurate positioning, beat production” scenarios, such as a cell phone assembly line, the speed chain conveyor line can be transported to the cell phone shell screw screwing, screen installation, quality inspection and other workstations in turn, each workstation through the blocker to control the residence time of the workpiece board, to ensure that the orderly connection of the processes.

Core Advantages

times speed conveying, high efficiency:

 the speed of the work plate is higher than the speed of the chain, under the same chain speed, it can convey the materials faster, which is suitable for the high beat demand of the production line.

Precise positioning and strong controllability:

 the blocking mechanism can make the workpiece plate stop precisely at any working position (the positioning accuracy can reach ±0.5mm), which is convenient for robots or manpower to carry out assembly, testing and other operations, and release the workpiece plate to continue conveying after the completion of the work.

High degree of flexibility:

according to the layout of the production line, it can be designed in the form of horizontal, climbing (≤5°), turning (90°/180°), etc., adapting to the complex workshop space; at the same time, it can flexibly increase or decrease the number of working stations to meet the production needs of different products.

Smooth running and low noise:

 the contact between chain and guide rail and work plate is rolling friction, low friction resistance, the running noise is lower than the plate chain conveyor, suitable for the workshop with higher requirements on environmental noise (such as electronic assembly workshop).

Moderate load:

 it is suitable for conveying light to medium-sized workpieces (the load capacity of a single workpiece plate is usually 50-200kg), and overweight will affect the life of the chain and the stability of operation.

Structural Composition 

Multiplier Chain:

It consists of chain body (roller chain) and special big roller, the diameter of big roller is usually 2-3 times of the chain roller (e.g. for 3 times speed chain, the diameter of big roller is 3 times of the chain roller), which is the key to realize “Multiplier”.

Workpiece plate (carrier plate):

 a panel that holds the workpiece, the bottom of which is in contact with the large roller of the speed multiplier chain and moves with the chain.

Guide rail:

supports the workpiece plate and chain, divided into upper and lower guide rails (the lower guide rail supports the chain, and the upper guide rail guides the workpiece plate to move directionally).

Driving system:

It consists of motor, reducer, sprocket, etc. to provide power for the chain.

Blocking mechanism:

 such as cylinder blocker, which is used to pause the workpiece plate in specific working position (such as assembly, testing position) to realize accurate positioning.

Tensioning device:

 adjust the chain tension to ensure the transmission stability.

Working Principle:

When the speed multiplier chain is in operation, the small roller of the chain (which engages with the sprocket) rotates with the sprocket wheel, while the large roller moves the work plate by friction. Since the diameter of the large roller is larger than that of the small roller, the speed at which the work plate moves (the linear velocity of the large roller) is 2-3 times the speed at which the chain itself moves (the linear velocity of the small roller), and thus it is called a “doublespeed chain”. For example, in 3 times speed chain, if the chain speed is 1m/s, the speed of the work plate can reach 3m/s, which greatly improves the conveying efficiency.
