90 degree turning conveyor line /Turning conveyor line /Belt conveyor line /Assembly Line Belt Conveyor

Product application field

Electronics industry:

 In the assembly line of cell phone, the 90-degree turn belt line shifts the main board from the welding station to the testing station, realizing the automation connection.

Logistics and Warehousing:

The courier sorting center uses roller turning lines to transfer parcels from the main conveyor line to different sorting lanes to improve sorting efficiency.

Food processing:

 In the cookie production line, the chain plate turn line conveys the baked cookies from the oven to the cooling area, adapting to the high temperature environment.

Core Advantages

High space utilization No need for manual handling or sorting, direct steering through the equipment saves space, especially suitable for compact production lines.

Stable and Reliable Conveying Equipped with guiding device, the materials are not easily shifted when turning, which is suitable for high-speed or high-precision conveying scenarios (e.g. electronic component assembly).

Flexibility It can be combined with linear conveyor lines, elevators, sorting equipment, etc. to adapt to diversified production processes.

Wide range of application It can convey small, large, regular or irregular shaped items, and can meet the needs of special environments through the selection of materials (e.g., anti-static belts).

High degree of automation Sensors and control systems can be integrated to realize linkage with other equipment in the production line (e.g. automatic counting, fault detection).

Structural Composition 

 Conveying Body 

According to the conveying material and demand, the common types include: 

Belt Type Turning Conveying Line:

adopts loop belt as conveying medium, good flexibility, suitable for conveying small and light parts (such as electronic components, boxes).

Roller type turning conveyor line:

 It is composed of several sets of rollers, which are inclined at a certain angle (e.g. conical roller), utilizing friction or differential speed to realize turning, and is suitable for conveying pallets, boxes and other heavier items.

Chain plate turning conveyor line:

 using chain plate as carrier, with strong load bearing capacity, suitable for conveying heavy workpieces or high temperature, oil pollution environment (such as automobile parts).

Turning section structure:

 usually curved design, equipped with internal guiding devices (e.g. guardrail, retaining edge) to ensure that the material remains stable during turning to avoid deflection or slipping.

Driving system 

consists of motor, reducer, coupling, etc., driving the conveying body to run, the speed of turning section and straight section should be matched to ensure smooth conveying.

Supporting and guiding device 

The frame is made of aluminum alloy, stainless steel or steel, and side baffles, guardrails or guiding rollers are set up at the turning point to prevent the materials from tipping over or getting out of the conveying line.

Working Principle

Through the continuous operation of the conveying body (belt, roller, chain plate, etc.), the material is brought from the straight section to the turning section. Turning section through the following ways to realize the steering:

Differential speed principle: 

turn inside and outside of the conveyor speed is different (such as roller turning line inside the roller speed is slower, faster outside), the use of the speed difference to make the material to complete the 90-degree turn.

Guiding constraints:

through the guardrail, baffle or guide rail to limit the trajectory of the material, forcing it to turn along the arc path.

Classification form 

(I) Classified according to conveying medium 

Belt type 90 degree turn conveying line 

Features:

smooth conveying, low noise, suitable for light and small parts, commonly used in electronics and food industry.

Application Scenario:

 In the assembly line of cell phone components, the parts are transferred from the transverse conveying line to the longitudinal inspection station.
Roller Type 90 Degree Turning Conveyor Line 

Characteristics:

Strong load-bearing capacity, suitable for pallets, cartons and other large parts, commonly used in logistics and warehousing, automobile manufacturing.

Key design:

the turning section adopts conical roller or differential roller to ensure the smooth turning of large parts.
Chain Plate 90 Degree Turning Conveyor Line 

Features:

 High temperature and wear resistant, suitable for heavy duty or special environment (e.g. spraying line, baking line).

Application scenario:

 automobile chassis parts conveying, need to turn between high temperature welding stations.

(II) Classification by control mode 

Manual adjustment type:

suitable for production lines with fixed product specifications, turning speed and guiding device need to be preset manually.

Automatic adjustment type:

 equipped with sensors and intelligent control system, it can automatically adjust the turning parameters (e.g. speed, guiding strength) according to the material size and weight.

Selection and design points 

Material characteristics:

 according to the weight, size and shape of the choice of conveying medium (such as light and small parts of the choice of belt, large parts of the choice of roller).

Turning radius:

 need to be determined according to the size of the material, too small a radius may lead to material dumping (generally recommended turning radius ≥ 2 times the length of the material).

Conveying speed:

 match with the speed of the front and rear sections to avoid blockage or accumulation.

Environmental requirements:

anti-static (electronic workshop), high temperature (baking line), waterproof (food cleaning line) and other special needs to be specified in advance.
Safety protection: set up emergency stop button and guardrail to prevent personnel from touching the running parts.
