4.2.2 Fastening material/vacuum hose

Note the flow direction (PU tubes only, optional), (see figure 4.4). Incorrect installation direction may influence the transport output.

Remove the wire spiral [1] from the tube and bend it inwards to make it contact the hopper loader.

Slide the material/vacuum hose on to the connection on the hopper loader and fasten the hose with a suitable hose band clip (see Figure 4.5).

CAUTION!

MATERIAL DAMAGE!Incorrectly attached material tubes cause transport problems and damage to the hop-per loader.

Lay out material/vacuum hose to the hopper loader with a sufficiently wide curve.Ground the hose.

Connecting the control cable

The electrical power is supplied from the controller via the controller cable (see figure 4.64.7).

CAUTION!

MATERIAL DAMAGE!Radiant heat and hot surfaces may damage the controller cable.

Lay out the controller cable so it will not be damaged by the heat of downstream units (hot surfaces or radiant heat)!

METRO 0.5 to 1.5Structure and function 5

Function

5 Structure and function

5.1 Function

In a hopper loader system with METRO H** and/or METRO M** hopper loaders one central Motancontroller controls all units in the system.

The different hopper loaders report a material requirement to the relevant controller and are then processed in succession.

METRO H**: Material required via the Proximity switch if the discharge flap is closed

METRO M**: Material required via the demand probe if the granulate no longer covers the demand probe.

If material is required by one or more hopper loaders, the blower station starts and generates underpressure in the vacuum line. The bypass valve on the filter closes and simultaneously open the vacuum valve in the hopper loader. An underpressure forms in the vacuum line and continues through the hopper loader to the material line through to the suction point.

Fig. 5.1 – Layout of the hopper loaders

[6] Material discharge module (bin loader)[7] Proximity switch (METRO H** only)[8] Multifunction panel METRO *P*[9] Material discharge module (machine hopper

loader)[10] Demand probe (METRO M** only)

5 Structure and functionFunction METRO 0.5 to 1.5


The aspirated air forms a mixture of air and granulate in the material line. The granulate falls down by gravity when it enters the hopper loader. The dust particles in the granulate pass through the screen filter and are removed by the central filter. This removes dust from the granulate at the same time.

Depending on the specified conveying time the vacuum valve closes to form an airtight seal. Because of the underpressure in the hopper loader the implosion valve now opens suddenly for a short time. The implosion cleans the screen filter after every loading cycle.

METRO H**: as a result of the implosion the underpressure in the hopper loader collapses and the weight of the granulate opens the discharge flap. The material flows into the machine bin.

The vacuum valve in the hopper loader opens at the next demand. The loading cycle starts.

Only one hopper loader at a time can be filled on a blower line.

If all hopper loaders are full and no material required is pending at the controller, the bypass valve on the filter opens, the blower aspirates fresh air and switches off after a specified run-on time. This reduces the load on the blower station.

If a hopper loader reports material required again to the controller, the blower station is switched on and a new loading cycle starts.

9 Maintenance and repairMaintenance and cleaning METRO 0.5 to 1.5


Prepare the hopper loader for maintenance (see "Maintenance and repair" on Page 32).

Open the spring clips on the top of the unit.

Open the cover.

Remove the screen filter.

Tap the screen filter to clean it and clean the screen filter with a vacuum cleaner.

Check its condition and if necessary replace the screen filter.

Structure

Insert the screen filter so the screen filter seal contacts the fastener ring [2].

Check that the screen filter [1] is correctly positioned, i.e. the rods of the filter fastener (see figure 9.2) are not in the vicinity of the vacuum valve.

Close the cover and lock it with the spring clips.

CAUTION!

MALFUNCTION!The required vacuum may not be generated if the rods of the filter fastener project above the hopper housing.

Never force the cover closed.Make sure that the screen filter is precisely positioned and that the rods do not project above the hopper housing.

Maintenance and cleaning

9.4.2 Check inlet flap

Prepare the hopper loader for maintenance (see "Before starting work" on Page 32).

Remove the screen filter (see "Clean screen filter." on Page 33).

Check the inlet flap [1] for wear (see arrows in the magnified view).

Note

The screen filter clogs up faster when regrind material is transported.

Reduce cleaning intervals appropriately.

Note

The air gap at the discharge flap ensures that particles of granulate on the discharge flap are sucked in by the vacuum at the start of transport.

The discharge flap is pulled up by the vacuum and forms an airtight seal.
