2.1 DESCRIPTION OF THE MACHINE

Alongside the traditional 4-shafts equipped shredders, I.S.V.E. proposes a series of single-shaft equipped shredders with pusher-drawer. These machines are purposely studied to shred thick materials and highly resistant to cut such as plastic blocks and sheets, various types of timber, paper, extruded polymer pipes, etc. Operation drawings: A pusher-drawer with hydraulic drive (4) pushes the material towards a tools-holder (3) roller (2) which carries out the first breaking and thanks to its rotation and to the COUNTER-BLADE action (6) makes a first breaking and the shredding of the product.

The product passes through a drilled screen, which allows establishing the final sizes of the material.

Detail of the roller (2) with the tools (3) Operation phases

1. Beginning grinding phase

2. Hydraulic drawer pushing action on the

rotor

3. Material advanced grinding

Note: in case of excessive effort, the

drawer might invert the direction to release

the material that had been loaded to avoid

structural overloads.

3.1 GENERAL REGULATIONS

I.S.V.E. has taken great pains in designing this family of machines and to make them as safe as possible; they have been equipped with all the necessary types of safety protection and devices felt to be necessary. They have also been supplied with the necessary information so that they are used correctly without running risks of accidents. As regards to “the lighting in the work place”, the room where the machine is housed, must neither have areas in the shade, irritating dazzling light or create dangerous stroboscopic effects. The room must also have good air circulation with possible use of an aspiration plant. The machine must be used only by qualified operators and it has been constructed to shred plastic scrap and other similar materials; the use of materials different from those indicated, can be

carried out only following written prior confirmation on the part of I.S.V.E.. The absence of this authorization, removes any responsibility on the part of the manufacturer for any damage to the machine, persons and animals. The behaviour of the operating, maintenance, cleaning, control, personnel etc, must comply in full with the accident prevention regulations of the Country the machine is operating in. We recommend the operator uses clothing suitable for the work place and the situation he finds himself in. The person in charge of the machine or responsible for maintenance should pay careful attention to the type of clothes worn, for example: - avoid using clothes which can easily get hitched to parts of the machine; - avoid wearing a tie or have clothing which flaps; - avoid wearing large rings or bracelets which could become entangled in the machinery . Before starting to use the machine the operator must be perfectly aware of the positions and function of all the commands and characteristics of the machine.

N.B.:

FOR THE EXACT QUALIFICATIONS OF THE OPERATOR SEE PARAGRAPH 0.4

Ordinary and extraordinary maintenance and cleaning operations must be carried

out when the machine is stopped and power has been switched off.

When carrying out electrical connections it is good practice to observe the general installation and connection rules and have them carried out by qualified personnel. It is strictly forbidden to camper with the safety devices on the machine; Operations with reduced safety must be carried out complying scrupulously with the indications supplied in the pertinent descriptions; For no reason modify any of the parts of the machine¸ in the case of malfunction due to non

compliance with the above, I.S.V.E. declines all responsibility. We advise you to write directly to the Manufacturing Company for any changes. Clean the machine coverings, the panels and commando, using a soft dry cloth or dampened with a bland cleaning detergent; do not use solvents such as alcohol or petrol in that they could damage the surfaces;

NOTE

The definition “qualified personnel” are those who have attended special training

courses etc. and have experience as regards to installing, starting up and

maintenance of machines.

3.9 RESIDUAL RISKS AND HAZARDS

3.9.1 RESIDUAL CUTTING RISKS

During the handling phases of the cutters and shredders (maintenance, calibration, replacement), there is the risk of getting cuts because of the sharp cutting edges of the cutters.

WARNING

The operator must use suitable individual protective devices, such as gloves with the

requirements as indicated in the EN 388 standard, he must also take the precaution

of covering the blades with rubber protections.

3.9.2 RESIDUAL RISK GENERATED BY NOISE

Even though the sound pressure level is within the safety limits, long term exposure to noise can damage the hearing of operators or other exposed individuals. Therefore, the use of a soundproof cabin, or at least adequate personal protective equipment like headbands, ear muffs, and earplugs is recommended.

Important!

The clothes to be worn and the means of protection must comply with the CEE 686

directives as regards to personal protection, or as an alternative according to the

regulations in force in the country of the user.

3.9.3 Residual risk caused by rotor blocking.

Should the conditions occur whereby one of the rotor blocks due to build up of material in the shredder chamber, the attempt on the part of the operator to rectify this situation could create a risk condition.

WARNING

Do not carry out impulsive or irrational actions.

The operator must carefully follow the procedure described in paragraph 7.13 of this

documentation to unblock the rotor.

4.2 TRANSPORT

The machine is usually forwarded on a pallet and protected by a cellophane covering. On arrival we advise you to check to make sure the machine has not been damaged during transport and if so to notify the road haulers immediately. Also check to see that the list of components of the supply in the packing list corresponds to what has been forwarded.

WARNING

Before lifting or moving the machine, check the weight shown on the packing and on

the plate attached to the machine itself.

4.3 LIFTING

Lift the machine using a lift truck suitable to the weight and overall size of the machine. When moving make sure the more delicate parts do not get damaged. Should a lift truck not be available, ropes or belts can be used as long as they have sufficient lifting capacity.

WARNING

During handling the machine must always be perfectly horizontal, no matter what

type of equipment is used to carry out the handling operations.

4.4 INSTALLATION

IMPORTANT

Make sure that the base the machine will rest on is compact, solid and perfectly flat

so that it can support the machine rigidly without any vibrations. The flooring we

recommend is reinforced concrete with smooth support surface.

POSITION THE MACHINE IN AN AREA WHICH IS LARGE ENOUGH SO THAT THE OPERATOR HAS THE NECESSARY SPACE TO CARRY OUT MAINTENANCE ON ALL FOUR SIDES. This machine has been constructed to operate without water being present. Furthermore the electrical components assembled, even if manufactured in compliance with CEE regulations, must operate in the absence of humidity or water; we recommend installing the machine protected from atmospheric agents and insulated from water which could be present on the floor.

Before modifying the shredder operation parameters contact the manufacturer’s

6.2.5 PRINCIPLE OF OPERATION Pushing the START OIL PUMP and the START SHREDDER MOTOR buttons, the motor and the tool-holding rotor are activated for the time set by the B001 parameter. If the operation for this interval is regular, the pusher drawer is activated. When the material is pushed over the shredding rotor, two situations may occur:

Pre-treatment: With the pressure of the pusher drawer on the material and the tool-holding rotor, the real shredding phase begins. The absorption of the motor is directly proportional to the resistance that the cutting tools encounter during the processing. If the absorption of current (set up in the B015 parameter) has a duration equal to or greater than the value set up in the B006 parameter, the process of the reversal of the pusher drawer is triggered. This mechanism serves to prevent overloads of the rotor and the motor itself. The return time of the pusher drawer is set with the B008 parameter.

Overload and unblocking procedure: If the absorption reaches the threshold value of 150% for a time equal to or greater than the B002 parameter, the rotor unblocking procedure is activated. The shredder will stop for the B003 time and reverses the direction of the tool-holding rotor following the settings of the B004 parameter. In this way it frees itself of the material overloading the cutting tools. The rotor will subsequently resume regular operation.

Manual unblocking procedure: In some cases it may happen that a piece of material blocks the pusher drawer. In this case the hydraulic control unit unsuccessfully attempts to push the material forward. To intervene the shredder must be stopped with the STOP SHREDDER MOTOR button and activate the MANUAL REVERSE FOR PUSHER DRAWER button. Insert other pieces in the hopper and reactivate the shredder pressing the START MOTOR push-button. In the event the procedure does not produce any effect,

intervene manually by removing the material from the hopper. BEFORE CONDUCTING

ANY MATERIAL REMOVAL OPERATION FROM THE HOPPER BE SURE THAT THE

MACHINE IS STOPPED, WITH THE EMERGENCY PUSH-BUTTON INSERTED, THE

GENERAL SWITCH OF THE CONTROL PANEL POSITIONED ON OFF AND THE

MACHINE’S PLUG REMOVED FROM THE ELECTRIC POWER SUPPLY.

7.1 MAINTENANCE

General Recommendations Before proceeding with any type of operation, carefully read the instructions in this handbook.

CAUTION

To proceed with any type of operation, trust only to specialized and expert figures

(see paragraph 0.4, operators qualifications).

- All maintenance operations must be executed with the machine shut down, disconnected from

the power supply and with the shredder outside its housing in the machine. - When the electrical equipment is powered, certain parts of this equipment could be

dangerous. - Behaviour not complying with the safety instructions for the use of this equipment could result

in injury to persons and damage to things. - Scrupulously keep to the instructions in the paragraphs regarding each maintenance

operation. After carrying out the maintenance operations and before beginning to operate the machine, check that: 1 Parts replaced and/or tools used during maintenance have been removed from the shredder. 2 All the safety devices are operating.

IMPORTANT

After the first day of operation check the tension of the transmission belt. The proper

tension is the minimum at which the belt does not slip. Also verify that the pulleys

are correctly aligned between them.

7 – MAINTENANCE I

7 - 3

7.2 WEEKLY MAINTENANCE OPERATIONS

HYDRAULIC SYSTEM: Pay attention that when starting the machine the hydraulic pusher drawer goes forward fluidly and that there are no oil leaks from the system;

Control that the limit micro of the pusher drawer (Fig. 07-01) works correctly and that it is good fixed to the supporting beam.

Fig. 07-01: Pusher drawer safety micro

Fig. 07-02: Pressostat

The motion of the hydraulic drawer is managed by a pressostat (Fig. 07-02) with manual regulation; control the regulation and integrity.

To access the hydraulic gearcase it’s necessary to open the closing carter unscrewing the screws (Fig. 07-03).

7.3 MONTHLY MAINTENANCE OPERATIONS

NOTE

These operations must be executed by a qualified mechanic.

7.3.1 Tensioning transmission belts

For the proper operation of the shredder, it is critical that the transmission belts are always tensioned. Proper tensioning reduces the wear of the rotor bearings, in addition, it reduces wear and the stretching of the belts themselves. For the verification and tensioning of the belts proceed as follows:

1 Put GENERAL BUTTON on."0” and unplug the electric net of the shredder

2 Unscrew the nuts rif. “E” - 07-04 for blocking of the hold-motor base;

Fig. 07-04

3 Fasten the screws rif. “F” - Fig. 07-05 for tensioning of the belts.

Fig. 07-05

IMPORTANT

Tighten the bolts Ref. “F” - Fig. 07-03 evenly so as to maintain the axis of the motor

sliding support perfectly perpendicular to the axis of the belts.

7 – MAINTENANCE I

7 - 5

When verifying the tension of the belts individually, if they are equal, it means that

the axis of the motor sliding support is in the correct position with respect to the

belts.

When the adjustment is complete re-tighten the nuts Ref. “E” - Fig.07-02.

7.3.2 Verification and adjustment of the transmission belts

Verify the tension of the transmission belts after 8-10 hours of operation and, if necessary, adjust them according to the values listed in the table. Verify the tension and integrity of the belts once a month. Every time the tension of the belts is adjusted, verify the tension again after 20-30 hours of operation at full load. To access the transmission, remove the protection guard (Fig. 07-06).

Fig. 07-06

NOTE

After each tensioning operation verify that the pulleys are aligned.

IMPORTANT

The table below lists the correct tensioning values of the transmission belts.

7 – MAINTENANCE I

7.3.2.1 Belt flexural rigidity calculation

To calculate the flexural rigidity of the belt make reference to the following formula:

Distance between the two centres (metres) X 16 = Total flexion (mm) For example, applying a given force (see Table A) in the centre of the belts mounted on two pulleys 1 metre apart with respect to their centres, the belts should flex down by approximately 16 mm in order for the tensioning to be correct.

The force necessary to flex the belts 16 mm for each metre between axles, can be obtained from Table A. If the force applied is greater, the belts are too tense, while applying a lesser force with respect to the value listed in the table indicates that the belts are too slack. For example, an SPZ belt with 1 metre between axles and mounted on a 56 mm diameter pulley will be correctly tensioned if a force of 13 Newtons or 1.3 Kg, flexes the belt 16 mm.

Total flexion = 1 (m) X 16 = 16 mm - Necessary force for the flexion = 13 Newtons Diameter small pulley: 56 mm

7.10 ROTOR UNBLOCKING PROCEDURE

In the case the rotor is blocked, caused by a possible accumulation of material inside the cutting chamber, and signalled by abnormal noisiness of the shredder, proceed in the following manner: - press the emergency stop button; - restore the emergency stop button; - open the shredder; - lock the general switch off; - clean the cutting chamber of the material still present.

WARNING

When the rotor is blocked absolutely do not clear it with hands, it can be extremely

dangerous.

Do not try to clear the machine by putting hands on the rotor, the blades or inside

the cutting chamber. Keep hands out of the rotor´s trajectory.

WARNING

Before conducting the following operations be sure to have your feet solidly on the

ground, that the pavement is clean and that your body is very balanced.

Pay attention the possible loss of balance that may occur as a result of the

unexpected unblocking of the rotor.

In order to clear the blocked rotor of the material, use a sturdy wood lever that is sufficiently long to keep the hands far from the trajectory of the blades, and apply pressure on the rotor in the opposite direction of the correct rotation of the shredder. In addition, use long tongs to remove the piece or pieces that provoked the blockage of the rotor.

After having unblocked the machine, manually rotate the rotor for a complete turn to make sure that there are no abnormal noises or friction. After completing that check, to restore working conditions all the checks already described in chapter 5 must be completed. For the possible adjustments necessary, make reference to the procedures presented in the present chapter.

8.1 FAULTS,CAUSES AND SOLUTIONS

The bad running of the pusher-drawer could be determined by different causes: • Mechanical problems; • Hydraulic problems; • Electric problems;

Mechanical problems. Check the absence of embedded material along front and rear guides, which could block the pusher-drawer. The fore guides can be visualized directly from the cutting chamber of the shredder.

Fig. 08-01

To verify the back guides open the upper ispection hatch of the grinder (Fig. 08-02)

CAUTION This operation must be absolutely done with unplugged machine from the electric net.

Fig. 08-02


8 - 3

Hydraulic problems: An oil-pressure station with a quite simple circuit controls the pusher-drawer. The main parts of this circuit are the reservoir, the oil pump and the control solenoid valve.

Oil reservoir Check if oil level is enough using the special level indicator. Check that the reservoir and the whole rest of the circuit don't have oil losses which could compromise the push pressure in the whole

The pump Check if the oil pump is working. After having given tension to the board, press the start-button of the pump. If the pump does not start, check the electric wiring or the motor running. If the pump turns but it does not put the oil in pressure, check mechanical parts. To open the pump it’s enough to remove the screws shown on the picture and the cover. Once opened, check if gears are integral and working.

WARNING This operation must absolutely be done with switched-off machine and the electric plug must be disconnected from the feeding net.


8 - 4

The solenoid valve The solenoid valve is necessary to manage the running of the oil-pressure piston. This is a quite delicate item because it works with an internal block with horizontal sliding, which determinate the oil passage. To check that the internal block is not embedded or damaged, it’s necessary to act on the manual controls placed by the side of the solenoid valve.

Using a pin or a key, press the metallic cylinder placed in the centre of lateral pivots up the bottom.

IMPORTANT: If after this operation the drawer works correctly, it’s sure that you have an electric problem. If the problem persists, it’s sure that you have a problem due to the oil pressure circuit.


8 - 5

The manostat The manostat is necessary to manage the working of oil-pressure piston. In fact it determinate the maximum pressure of push over which the solenoid valve commutates and the drawer reverses the movement. Verify that the manostat is entire, working and connected to the relative wirings. Besides check that the pressure level regulation is correct.

Electric problems: The bad working could also be caused by problems on the electric equipment. Please check the following points:

Check that wirings are integral and cables are well sold into the terminal boards.

Check that the FU3 fuse placed to protect the control line is not burnt.

Check the correct running of the relè that control the pusher-drawer (KA5 e KA6);

Check if solenoids, which manage the solenoid valve, are working. These devices are equipped with a confirmation luminous led.

After having put the oil-pressure pump in activity and press the pusher-drawer controls placed behind the electric board, solenoid lights turn on to confirm the operation.

8.2 ELECTRICAL FAULTS

The following pages list some faults which may occur on the shredder. These general indications, enable location of possible faults and how to proceed to repair them rapidly. In all events, when searching for the causes, it is a good rule to start with the simple checks before beginning to carry out difficult disassembly operations and trying unnecessary solutions.


Machine blocks Safety switch has interrupted the circuit. Relay switch disconnected.

Check to make sure the knobs which trigger the safety switch are tight. Check calibration.

The machine does not start up No current. A thermal switch on the motor has triggered Overload block. The safety switch is broken. Cutting chamber too full.

Check fuses. Press the button of the “motor” thermal switch inside the switchboard. If the fault repeats, it may depend on the fact that the relay is calibrated too low. In this case, turn the black disk placed on the aforesaid relay anticlockwise using a screwdriver making sure not to exceed the value of the ammeter on the plate of the motor. If the fault remains it could be that a piece of wood is stuck between the cutters preventing start-up. Check amps on electric motor Check and repair. Remove material from cutting chamber.

The motor starts but does not pick up speed

Too much tension on the transmission belt. Motor improperly connected to the power source.

Verify the tension of the belt and adjust it. Re-do the electrical connections properly.

The motor starts but does not pick up speed

Bearings too worn Cutting chamber blocked.

Replace the bearings. Clear out the cutting chamber.
