Elevator or lift platform

6.21.1 Functional description

The lifting elevator function is integrated in the palletising function.

The lift function drive is designed for a specific maximum pallet weight of

1500 kg.

A pallet is positioned on a pallet roller conveyor.

This pallet roller conveyor is integrated on a lifting platform.

For optimal handling / energizing the unit is equipped with a guided

counterweight.

The pallet is lifted to a position under the loading platform (stripper table),

depending on the actual height of the pallet.

The loading platform opens and a layer is dropped on top of the pallet (or

pallet load).

Now the pallet(load) is lowered in high speed until the top of the pallet(load)

is under the loading platform.

Then it will raise the pallet(load) in slow speed back towards the platform

for the next layer to be accepted.

sticky tape, packaging and product remnants, glass fragments,

wood splinters etc. must be removed immediately .

- Please shut cable tracks correctly and insure that connections andinternal sections are not damaged or loose.

- Cables and pneumatic hoses (if applicable) must not become

twisted or jammed. Please also ensure that there is enough play for

lengthwise movement in the cable track.

- Cables and hoses must be secured with a pull relief on outer ends

of cable tracks.

6.21.5 Replace the lift chains and/or lift shaft bearings

General

Warningw The counterweight must be blocked mechanically.For that reason a blocking provision (See Fig. 6.8 Safety Blockage

Positions 4/5 & 29/30) has been fitted on each side of the frame.

Each blocking provision has two blocking pins. ( See Fig. 6.7 Safety

blockage lift platformpositions 3) In total four counterweight blocking pins

have been fitted.

Check prior to works

1 Check that the platform is empty.

(No load allowed on the conveyor.)

2 Bring the lift platform up and the counter weight down (Using the manual

control on the main operator panel)

Required: lift platform on high level for easier access.

6.21.5.1 Operation

Warningw The work must always be carried out by two persons.6.21.5.2 Tools required:

6.21.5.3 Chain

Lift chain needs to be exchanged if the elongation is more than 3 %

1 Open the door

The safety cylinders will go out (on spring actuation) and at least one of the

cylinders will be captured in the safety profile. (See Fig. 6.7 Safety

blockage lift platform)

On each side of the elevator frame a blocking provision is mounted on the

outside (see Fig. 6.8 Safety Blockage Positions 4/5 & 29/30).

2 Remove the two dummy bolts M20 positioned in the provisions (one

each) side and approx 700 mm height. holes in the elevator frame will

occur.

3 The locking pin (See Fig. 6.9 Position 2) can now be taken from the

blockage provision. (see Fig. 6.8 Safety Blockage Positions 4/5 & 29/

30).

Keep the pins with you for further handling.

1 Place the dummy M20 into the (now) free slot (position) of the blocking

provision.

Chains must be set slack on both sides

1 Switch to manual mode (using the manual control on the main operator

panel)

- One person to Lower the lift platform and raise the counterweight in

manual operating of the elevator.

- One person on the outside of the fencing to visually check when the

bolt slot(s) become free. The counter weight must be above the bolt

slots.

2 The operator can now stop moving the elevator.

3 Mount the locking pins in the blocking provision for the counterweight

from the outside.

(See Fig. 6.8 Safety Blockage Positions 4/5 & 29/30)

The pin to enter into the profile of the moving area of the counterweight.

4 When all four pins are installed, the operator must raise the platformshortly and lower the counterweight onto the pins. (using the manual

control on the main operator panel)

The chains to the counterweight now become slack.

5 Open the door.

The safety cylinders will go out (on spring) and at least one of the cylinders

will be captured in the safety profile.( See Fig. 6.6 Overview Palletiser

position 7.1)

Warningw Normally we will be needing some kind of slack of the chainIn order to work safely the strong hold of the lifting platform on the lifting

chain should be eliminated!

Create slack on the chains to the lifting platform.

Noten See Fig. 6.6 Overview Palletiserpositions 7.1 and 7.21 Lift by hand the brakes of the elevator drive so that the platform will drop

downwards until the lift blockage system will stop the movement.

One of the safety cylinders is now against the bottom of the hole in the

safety catching profile.

For removal of the drive the lift a rope must be tightened in such a way that

it can be shifted to one side.

Note

nMake sure the drive does not drop down when it comes off the shaft!

Torque arm

After the drive is secured we can now safely remove the torque arm

support.

Noten The drive still remains on the shaft.Noten The shaft will not start turning because the blocking mechanism preventsthe chains to move the shaft.

If you only want to exchange the drive it is not required to use the

counterweight mechanical blockage system.

1 Lift drive motor and lift chains

a Lift drive motor is to be removed from the shaft before the lift

chains can be accessed.

b Pull the drive from the shaft (Use pulley wrench if necessary).

Note

nSee item 8 and make sure the drive is held properly by the liftingequipment and rope(s)!

c Replace lift chain on the drive motor side.

2 Remove the bracket (16) from the top frame on the drive motor side.

This is one of the connections between the lift frame and top part.

Now the lifting chain on the drive motor side of the elevator is free.

Warningw Mind the weight of the chain!3 Visually check the chain for wear and tear.

If necessary exchange the chain.

Noten If chains and or bearings need to be replaced always exchange bothbearings and or chains during the stop.

a Check the status of the chain sprockets.

When chain sprockets are worn (and or if there is play between the

key connections and the chain sprocket and drive shaft) and they

need to be replaced continue with item 18.
