Introducing the HepcoMotion DLS Linear Transmission To satisfy increasing customer requirements, Hepco has upgraded its popular DLS range of linear transmissions. Customers wishing to make their own arrangements for the drive may purchase any Hepco DLS with a drive shaft. 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...

System Composition Standard Axis The Hepco DLS provides the complete solution to linear drive problems. It has been engineered with all the options required to enable it to handle almost any linear positioning application. The illustration below shows a unit with a fitted AC geared brake motor, which also has the optional output shaft (to enable direct coupling to a second unit, see page 7). It is fitted with a microswitch mounted using a switch bracket, and this switch is operated by the switch cam which is shown attached to the carriage. The DLS unit can be attached to a mounting base using...

System Composition Cantilever Axis 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....

System Composition Ancillary Mechanical Components Hepco can provide the components which are required to turn the mechanical transmission into a complete positioning unit. Precision Planetary Gearboxes. Hepco 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...

Application Examples Sheet Feeding Mechanism 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...

Application Examples X-Z Transfer Unit 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. The 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 the Hepco 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...

Application Examples X-Y System The master X-axis transmission is shown fitted with the Hepco high precision planetary gearbox and a servo motor. It is connected to the slave X-axis by the Hepco 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...

Data & Dimensions DLS3 & 4 Standard Axis = = The important dimensions of the DLS are shown in the drawing and table below. The main picture shows the DLS in standard form, with an input shaft. Details of gearbox and geared motor options are included on page 9.

Data & Dimensions AC Geared Motor Option The optional AC geared motor will be the preferred choice for many applications as it provides an excellent combination of power, accuracy, flexibility and value. It is ideally suited to be used in conjunction with the Allen-Bradley Smart Speed Controller (see page 13) to produce a complete linear positioning system. Hepco offers 3 phase squirrel cage motors to VDE 0530 supported by DIN 42677. Motors in 4 IEC frame sizes from 56 to 80 are offered, each with the choice of short (S) or long (L) field windings and 2 or 4 pole designs (running at approximately...
