Transport and transfer solution

1.Conveyor

The key element of the project is a twin-track modular conveyor produced by Bosch Rexroth - TSplus. It is used to transport and transfer the assembly parts form the entrance of the system, between assembly stations and to the way out. All components of theTSplus system are pre-engineered and modular.

  a) Workpiece Pallet
The component who decides the design of the transport system is the workpiece pallet. They are used to carry the assembly pallets. TSplus conveyors transport parts on workpiece pallets. The workpiece pallets (160 x 160 mm) ride on the surface of the conveying medium. This transport method has many advantages for product assembly applications, including:

Positioning

Pallets are positioned at workstations to ± 0.002 inches when used with a Rexroth Lift-Position Unit, permitting precision assembly operations.

Mounting

Pallets can be tooled with fixtures to secure parts for manual or automated operations. Identification and data carrying devices (used to coordinate assembly sequences, identify model types, etc.) are also commonly mounted to pallets.

Stopping

Pallets can be stopped on the leading or trailing edge - regardless of pallet orientation on the conveyor. Pallets can also be accumulated in queue and released one at a time.

Sensing

Exciter plates on the pallet bottom and sides work with conveyor-mounted proximity switches to sense pallet presence. Pallet orientation and routing can be controlled using Rexroth ID/10 or ID/80 identification systems.

  b) Longitudinal conveyor
The role of the longitudinal conveyor is to transport pallets in a closed loop

  c) Leg Set
The structure of the conveyor is supported by an aluminium frame composed of pair of adjustable(only during the mounting stage) leg sets.

  d) Motor
The drive module(motor) drives the belt. The motor can be mounted suspended or horizontally.

  e) Lift Transfer Unit
The electrical transverse conveyor is used to join two parallel longitudinal conveyor sections with a conveyor separation > 320 mm. All the transport belts for the electrical transverse conveyor are driven by the same motor. Along with the workpiece pallets, the lift transfer units are the key elements of the system.
