3.6.2 Replacing the Complete Drive Unit [00359284-xx] Modular PCB Conveyor System

Service Manual SIPLACE X Series 153

Removal

► Switch off the machine and secure it to prevent unauthorized reactivation.

► Push the Y gantries into the area outside the PCB conveyor.

► Mark the allocation (+/-) of the cable connections (1). This is important for the direction of rotation!

► Disconnect the cable shoes from the motor terminals (1).

► Strip the heat-shrinkable sleeve, (2) used to fasten the connection cable, from the circumference of

the DC geared motor.

► Remove the three screws (3) holding the motor mount in place (5).

► Move the conveyor so that you can easily access the

screws fastening the motor fixtures (3). The convey-

or position with the best access may vary, according

to the conveyor type and area.

► If the drive on the outer fixed edge (single/dual con-

veyor) is replaced, use the machine SW to adjust the

edge until you can access the fixtures for the hexag-

onal shaft. You may need to change the conveyor

mode to fixed side right/left. Make sure that there is

still a gap of 120 mm between the conveyor edges for

the lane concerned.

► Undock the changeover tables to give you more

space to move.

NOTICE

Loosening the deflection pulley

If necessary, loosen the deflection pulley with slot (6). This will make it easier to unthread the

motor mount. The position of this deflection pulley may vary, according to the conveyor area.

4. Retaining washer

► Single/dual conveyor: Disconnect the hexagonal

shaft from the conveyor edge (see diagram).

► Quad lane conveyor: First loosen the clamp on the

drive between the conveyor edges.

CAUTION

Do not damage the toothed belt!

The toothed belts must not be stretched or kinked!

► Single/dual conveyor: Loosen the circlip on the hexagonal shaft and unthread the motor from the

hexagonal shaft.

Quad lane conveyor: Push the drive plus hexagonal shaft to one side and loosen the clamp on the

outer side of the drive. Push the hexagonal shaft off the drive.

NOTICE

Observe how the belt is run

The way in which the conveyor toothed belt is run around the belt guide depends upon the

transport area concerned. Please observe this belt guidance during assembly.

If you have discovered a break in the motor cable during a continuity check, the motor cable

must be unthreaded as far as the conversion board of the conveyor edge (see circuit diagrams

of the same name) and unplugged at the corresponding point. This might be somewhat com-

plicated depending on the routing of cables inside the machine base.

► You may wish to contact SIPLACE service team regarding this work if you are unsure about

how to proceed.

► Fit the new drive unit in the reverse order.

► Please check:

⇨ The entire width of the conveyor toothed belt (1)

must engage at all toothed disks (2) and be run

around the belt guide (3).

⇨ See also "Adjusting the Tension of the Conveyor

Toothed Belt".

► Perform a function test.

NOTICE!

Function test via the station software

After the new drive has been installed, you must make

certain that the direction of rotation and the conveyor

speed (motor voltage) are correct. After connecting the

geared motor, you only need to check the direction of ro-

tation.
