To satisfy increasing customer requirements, Hepco has upgraded its popular DLS range of linear transmissions.A new range of cost effective, high quality AC geared motors and worm gearboxes has been added to create a complete linear drive solution which is ideally suited to many positioning applications. Motors up to 1.1kW are offered as are gearboxes with ratios from 5:1 to 75:1. This provides driving forces to 1225N and linear speeds from zero to 2m/s (up to 5+m/s for systems using special motors). The reduced engineering package gives the power, flexibility and reliability of an...

The cantilever axis is particularly useful in Z-axis or horizontal pick and place applications. It is intended to be used with the beam moving on the carriage, as opposed to the standard DLS where the beam is stationary. It is available in size 3 only.Supplied with the lightweight beam as standard, this arrangement offers rigid support for cantilever loads with the minimum of inertia. It is particularly useful in the context of a multi-axis system (see application examples on pages 6 & 7) where the DLS3C is mounted onto the carriage of a standard DLS axis.The DLS3C can be offered with...

Bishop-Wisecarver can provide the components which are required to turn the mechanical transmission into a complete positioning unit. Precision Planetary Gearboxes. Bishop-Wisecarver will supply any DLS with a planetary gearbox in an appropriate ratio engineered into the drive end unit. These gearboxes are very efficient and accurate, have a high load capacity, are very compact, and are compatible with many electric motors. Their high performance makes them particularly suitable for use with servo motors. Worm Gearboxes . A high quality right angle drive unit which is directly coupled to...

The ability of the DLS to feed to a length is used in a sheet feeding mechanism for a vacuum moulding process. The AC motor is driven using the inverter, which in turn is controlled by a PLC which supervises the whole process. After a start signal from the PLC, the motor drives the axis until a limit switch signals to the PLC that the required length is achieved. The PLC can then instruct the remaining part of the machine cycle to proceed. The length can be varied to suit a particular mould size by either moving the switch, or having several switches corresponding to different mould tools....

Used in automated system for picking up a basket of components, placing them in a cleaning tank and then returning the basket for subsequent processing. This unit uses a DLS3 standard unit with fitted AC geared motor for the X-axis, and a cantilever axis for the vertical Z-axis. The cantilever axis is fitted with a brake motor option to provide a holding force while this axis is stationary. The unit has a number of stations on the X-axis defined by limit switches, and a PLC controls the whole process, commanding moves from any starting point to the target position in the cleaning tank....

Motion Without Limits > The master X-axis transmission is shown fitted with a high precision planetary gearbox and a servo motor. It is connected to the slave X-axis by a transmission shaft connecting between the output shaft of the first X-axis and the input shaft of the second X-axis by flexible couplings. The Y-axis transmission also has the same motor and gearbox arrangement fitted. It is connected to the carriages of the X-axes using the long fixing clamps which fit directly onto the carriage plate mounting holes. Both master X-axis and the Y-axis have a switch cam on the carriage and...

Having selected the right motor/gearbox combination, the user should then evaluate if any options are required for the geared motor: > The brake lining is spring loaded against the friction plate, so the brake coil must be energized to release. In the event of a power failure, the brake is applied, so the unit is fail safe. The brake fits under an extended fan cowling on the end of the motor. Dimensions are shown on page 9. The brake requires nominal 200-230V AC power (which is rectified for the DC coil). This means that the brake should not be connected in parallel with a motor phase if...

A critical feature of the DLS system used in conjunction with an AC geared motor is that it does not have any position measurement or feedback, with positioning dependent upon the unit having a switch at the desired stopping or reversing position. If the unit advances to a switch, the ramp down command is issued as the switch closes, however as some time is required for the system to stop, then the carriage will overshoot the switch position by a distance which depends on the approach speed and the deceleration time. In high speed systems, this overrun can be quite substantial (10ْs of mm)...
