To shorten the drive chain, please proceed as follows:
  1. Disconnect the electrical supply of the entire conveyor system and secure against reconnection.
  2. Remove the 228 mm long top rail extrusion above the drive station.
  3. Turn the fan of the drive motor in the direction of flow to drive the conveyor manually until a master link is visible (zinced).
    CAUTION: There is a residual danger because of the non covered chain drive.
  4. Remove the clear front cover of the drive station and release the chain tensioner. Lock it in that position with an adequate device.
  5. Open the master link, and pull the chain to tension and shorten the excessive chain.
  6. Re-connect both chain ends with the master link. Pay attention...

LOGOMAT automation systems, Inc. offers different types of drive stations which get used in different applications. Roller conveyors with a bi-directional flow need a reversible drive station with two chain tensioners.

The drive stations that are installed in your conveyor system are listed in the conveyor parts list in detail.

Overview of the different types of drive stations:


To change the end roller, please proceed as follows:
  1. Disconnect the electrical supply of the entire conveyor system and secure against reconnection.
  2. If covers between rollers are installed, remove them by pushing them out from the bottom.
  3. Remove the chain covers between the two last rollers of the conveyor section, as described in the previous chapter.
  4. Remove the plastic chain end support.
  5. Loosen and remove the mounting bolts of the end roller. Relieve the end roller against the chain tension by hand to remove the bolts.
  6. Release the end roller by turning in slightly from the drive chain and remove the end roller sideways (the same way as the friction roller).
  7. Install the new end roller...

    Roller Changing end roller


To change or relocate a friction roller, please proceed as follows:
  1. Disconnect the electrical supply of the entire conveyor system and secure against reconnection.
  2. Remove the chain covers in the area around the roller(s) to be replaced or relocated.
  3. Loosen and remove the mounting bolts of the rollers (M8 socket head bolt with hexagon socket size 6 mm).
  4. To take the friction roller out, release the roller from the drive chain by twisting or sliding sideways. If relocation to an adjoining mounting position is planned, the roller can be shifted sideways.
  5. Remove the friction roller (aslope) upwards.
  6. Install the new roller in reverse order.

Only KRUPS Standard Rollers with adjustable nut and silver or golden spring can be adjusted in their friction.
Rollers with a silver spring generate more friction than the gold spring rollers but share the same internal structure, allowing the spring to be changed to increase tension when needed. Warning: Too much friction can wear out the bottom of the pallet.
 
The friction rollers can be adjusted (increased or decreased) by turning the adjusting nut on the axis of the roller with an open-end wrench size 22 mm until the required transportation force is achieved. The adjustment range is predefined in all types of rollers because of the existing thread length.
Tightening the nut increases the...

Roller Adjustments



The stub rollers get used if free center access through the conveyor is necessary. The reason can be operations with tooling from underneath or the installation of components like lift and locates or rotates.
 
A continuous section with stub rollers should not exceed 1,000 mm in length. The driven stub rollers have to be arranged in a pitch of 57 mm to generate sufficient friction to transport the pallet safely. The pitch of the non-driven stub rollers can be 114 mm because they just support the pallet. If a stub roller area needs to be longer than 1,000 mm a friction roller, or at least a roller shaft, has to be installed to maintain the strength of the conveyor frame.

Please position and secure the pallet upside down for a better handling.
 
To change the pallet stop insert, please proceed as follows:
  1. De-install and remove the attachment bolts and the lock washers of the stop insert.
  2. Remove the stop insert with the return stop flapper with suitable tools.
  3. Insert the new stop insert and the return stop flapper in the intended opening. Make sure that the PU damping strips are inserted and the stop insert is even on the bottom of the cutout.
  4. Insert and tighten the attachment bots with the lock washers. Make sure that the heads of the screws are not protruded beyond the stop insert but also that the bolts are not too tight because it is just bolted into...

For working on the side guide rollers, a free access has to be given to the attachments of the side guide rollers. Please remove attached top plates or any structure on top of the pallet, if necessary.
 
To change the side guide rollers of a pallet, please proceed as follows:
  1. Remove the clamping bolts of the hold down device and remove those.
  2. Drive out the shaft of the roller with a pin punch of 3 mm until the side guide roller can be removed.
  3. Install the new side guide roller in the reverse order as described above. Make sure that the axis is not set up too low, the roller is flexible and can rotate freely and the bolts of the hold down device are not tightened too much, because it is just...
