Cautions on the CAD data
-
Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
You will need to edit the Data so that it meets your specific design conditions. -
The CAD data unit assembly consists of sub-assemblies.
Each sub-assembly unit can be used as it is or can be edited. - The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
- The Data including the third-part components are made by the Company.
* The part in the frame is a sub-assembly unit.
-
- * Unit assembly CAD data consists of some sub-assemblies.
Each sub-assembly unit can be used as it is or can be edited.
Application Overview
Purpose
- A structure in which dust is removed from a workpiece utilizing ring blower from all directions while the workpiece is transferred by a conveyor.
- Air blow from all directions is achieved by means of a ring blower.
Points for use
- Automatic transfer achieved by pushing a workpiece on the conveyor with a pusher
- The cover prevents dust from leaking out.
- A V-shaped pusher is configured as a part of another unit and transfers workpieces.
Target workpiece
- Bottle in bowling pin shape (resin).
- Outer dimensions: D200 x H340mm.
- Workpiece weight: 570g.
- Workpiece volume: 0.0065 m³ -> 6.5L.
Design Specifications
Operating Conditions or Design Requirements
- Outer dimensions: W608 x D628 x H1376mm.
- Conveyor length: 595mm.
- Conveyor roller strength: 273N.
Required Performance
- Ring blower air discharge amount: 2.5m³/min at maximum.
- Air volume discharged from one nozzle: 0.0694m³/min.
- Air speed discharged from one nozzle: 37.11m/s.
Selection Criteria for Main Components
- Conveyor.
- A conveyor that can withstand the weight of workpieces filled with water is selected.
- Workpiece weight 5.7N + water 65N = 70.7N < conveyor roller strength 273N.
- Nozzle (adjusting hose).
- Two types of nozzles with different hose lengths are selected so that the entire surface of the workpiece is blown.
- Ring blower.
- A ring blower is selected to address the number of nozzles.
Design Evaluation
Verification of main components
- [Air speed is verified based on the air volume per nozzle.]
- [Air volume<per nozzle>.]
- Air volume = ring blower air discharge amount/number of nozzles = 0.0694m³/min.
- [Air speed<per nozzle>.]
- From the nozzle outlet diameter of Ø6.3mm, the nozzle outlet sectional area is,
sectional area = (3.15 x 10⁻³)² x π = 3.117 x 10⁻⁵m².
- Air speed = air volume/(nozzle outlet sectional area x 60)
= 0.0694/(3.117 x 10⁻⁵ x 60) = 37.11m/s.
- From the nozzle outlet diameter of Ø6.3mm, the nozzle outlet sectional area is,
Other Design Consideration
- A cover is attached to prevent dust blown by air from leaking out.
- Leveling mounts with casters are selected to facilitate relocation of the unit.
- Adjusting hoses are used so that the air blow directions can be adjusted on site.
- As the attitude of the workpiece is maintained as it is pushed by a V-shaped pusher of another unit, no workpiece guides are installed in particular.
