Linear transfer system
LS280

With LS280, WEISS has transferred benefits of the Rotary Indexing Table over to a Transfer System. This concept shortens the transport times and thereby increases the productivity. The modularly designed system can be expanded as needed.

Feature

LOCKING STATION
LS280

The locking stations are designed for transporting and positioning multiple workpiece carriers at the same time. Depending on the cycle stroke and design, a different number of locked processing positions is available.

  • Positioning accuracy of ± 0.03 mm in the x- and y-directions and ± 0.06 mm in the z-direction
  • Different strokes (70, 140, 280, 560 mm)
  • Short transport times
  • Available as a single or double locking station
  • Up to 28 locking stations on one LS 280 are possible

Feature

BELT SECTION
LS280

The belt sections transport the workpiece carriers between the locking stations. They decouple the individual cell modules and also act as little buffers outside the processing stations.

  • Available in different lengths and transport speeds

Feature

WORKPIECE CARRIER TRAIN
LS280

The workpiece carrier train consists of two workpiece carriers connected as a train. Transportation occurs on a continuous rail system. The hardened and polished profile guideways ensure a long service life and high degree of accuracy.

  • Workpiece also accessible from underneath
  • Loading up to 4 kg (weight of workpiece + its holders)
  • Stationary support of the carrier plates is possible at high process forces
  • Standardized carrier plates available in three sizes, optionally with customer's hole pattern
  • Optionally with RFID transponder

Feature

Base frame
LS280

The base frame is the stable foundation of the LS280. Additional handling components such as HP Pick & Place Modules can be mounted here simultaneously.

  • Stable design
  • Handling components can be integrated without a substructure
  • Central lubrication unit is optional
  • Standardized carrier plates available in three sizes, optionally with customer's hole pattern
  • Standard mounting plates are 1199 x 320 mm and 1199 x 480 mm, optionally with customer's hole pattern

Feature

REDIRECTION MODULE
LS280

The redirection module enables the LS280 to have a space-saving design and variety of uses.

  • Available in two versions
  • 180° redirection module for a linear design
  • 90° redirection module so that the face ends can have process stations attached

Benefits
LS280

The benefits of the LS280 are the result of a well-conceived operating principle.

  • Higher cycle rate increases the output
  • Simple, reliable motion principle
  • Workpiece carrier transport optimized for low level of jerking and jolting
  • Compensates for different process times
  • Highly reliable thanks to maintenance-free operation

Feature

Controlling
LS280

The W.A.S. Control Package simplifies the process for configuration, commissioning and adaptation to customer requirements. At the same time, it is fast and easy to connect to the higher-level system control.

  • One master PLC per LS280 base machine
  • Centrally stored parameter file
  • Fieldbus interfaces for customer interface:
    Profinet/Profibus, EtherNet/IP, EtherCAT
  • Hardware capable of multiple voltages (400/480 V 3ph / 50/60 Hz)
  • Frequency converter with integrated restart interlock Safe Torque Off (SIL 2, PL "d")

CONFIGURATIONS
LS280

Depending on the final product, there are different machining, assembly and production processes. WEISS designs and builds your LS280 in accordance with your requirements, drawing from numerous combination options.

Double twin

The platform needs an area of only 4.8 by 9 m and offers the user a total of 21 workpiece positions (14 + 7). In this example, the cycle strokes used are at 140 and 280 mm.

Offset arrangement

This version has a total of 29 workpiece positions in an offset arrangement. Cycle strokes of 70, 140, and 280 mm can be implemented here. The space requirement of this LS280 version is 9.6 x 0.9 m. Due to the offset arrangement, there is more space for potential attachments.

Offset twin arrangement

With a total of 13 workpiece positions, the LS280 twin version can also
be used in an offset arrangement. The width of the subsystem remains
at 0.9 m. The length is 7.2 m. The cycle strokes are 280 and 560 mm.

90° arrangement

This arrangement allows for processing stations to be implemented at the redirection modules. The footprint of this LS version is 4.5 x 2.5 m. It is designed with a cycle stroke of 280 mm and offers a total of 14 workpiece positions.
