1.0 INTRODUCTION

Since the dawn of civilisation, man has been continuously trying to ease

and improve his work by developing better tools. This process started with the

development of stone tools and will culminate into development of a totally

automated factory. This factory would be able to do all the things associated with

a product, right from designing it to packaging. Since the human operator tends

to be the weakest link in the production process, the need for automation has

been felt throughout the industry. A Flexible Manufacturing System (F.M.S.) is a

part of this process and a step towards complete automation of the factory. This

system automates the metal cutting part of the product manufacturing. A F.M.S.

is a form of flexible automation in which several machine tools are linked together

by a material-handling system, and all aspects of the system are controlled by a

central computer.

STATION 7 ( FMS – 207)

3.0 SAFETY,HEALTH AND ENVIRONMENTAL DOCUMENTS AND

STANDARDS

GENERAL SAFETY PRECAUTIONS

Once the process has begun, care must be taken to avoid adding pieces to, or

removing pieces from, the respective stores or pallets in circulation.

In general, the stations should not be manipulated with whilst the machine is

running.

When proceeding to the disassembly of the mechanism, do not leave any

pieces behind inside the main body.

Under no circumstances must the protection and safety devices described

below be tampered with.

If the stations have to be physically dealt with after a halt, to extract a fallen

piece. For instance, always press the emergency stop mushroom head down

until the intervention is completed. If some damaged element has to be

replaced, we must open either the sectionalising switch on the button pad or

the one the transfer unit, as circumstances require.

In order to safeguard the cell components, care must be taken to stop foreign

bodies or obstacles from entering the stations.

PROTECTION AND SAFETY DEVICES

All the stations and the transfer unit are equipped with emergency stop

mushroom heads for stopping the process at any moment in order to prevent

accidents. If the emergency stop mushroom is used, once the incident that caused the

stop has been overcome, make sure, before reactivating the cell or station, that the

situation will not recur, by taking appropriate measures. Furthermore, it is advisable

to take away pieces that are in the middle of a cycle whenever possible. After freeing

the emergency stop mushroom it will be necessary to press button so that the

components return to their starting mode positions.

2

There is also a pneumatic device at the general air input, which causes a

gradual increase in air pressure when the air is connected, thus avoiding accidents

produced by the sudden input of air in the circuit.

Stations 3 (press) has a protection fairing to prevent accidents occurring with

the press. It descends when the latter is working and goes up when the task is

finished.

Stations 7 and 8 (robot and store, respectively) there is a protection fairing

that covers the entire station. We must be sure that all the gates are closed before

running these stations. The gates should never be opened with the station running.

MAINTENANCE PROCEDURES

PNEUMTIC COMPONENTS

In general, the pneumatic components of the FMS200 are lubricated for life

and there is no need to carry out any maintenance of this kind on them. It is

possible that, over a long period of time, the internal gaskets of the cylinders

may suffer from attrition. In this eventually, if the cylinder is detachable the

gaskets have to be replaced. If it is not detachable it will to be replaced by

another cylinder.

It is recommendable every so often to carry out periodic bleeding of the water

that accumulates in the cell’s air conditioning units. The filter condensate

level should never go the maximum indicated on the filter bowl.

If the filter pressure drop higher than a bar is detected, the cartridge filter must

be replace with a new one.

ELECTRICAL SHAFTS

The electrical shaft on station 8 require periodic inspection : after every six

months of continuous work or after a month at standstill. This inspection must

involve a check on the unit holding elements, such as screws and nuts, in case they

are loose. It is also necessary to clean the feed shaft with the right kind of grease,

3

moving the carriage backwards and forwards. The linear guide runners hav to be

greased as well, using an appropriate tool. Important Note : The grease used must not

contain fluorine.

CLEANING

For the periodic cleaning operations on the FMS200 a clean cloth that leaves

no fibre traces can be used, whilst it is not advisable to use any cleaning product, in

particular those containing alcohol, solvents or chlorinated compounds.

SAFEGUARDING

Safeguarding includes the use of safeguards such as interlocking guards,

awareness means in addition to the safeguards, and safe working procedures to

reduce the possibility of injury while performing an assigned task.

Here, the guidance on safeguards and awareness means are provided for customers to

check their safeguarding

SAFEGUARD

1. Fixed guards must be installed outside the maximum space of the robot.

2. Fixed guards must be constructed to withstand foreseeable operational and

environmental forces.

3. Set the fixed guard to prevent entry into the protection region (inside the safety

fence) from entrances other than those provided with an interlock device or presence

detection device. (So that an operator cannot climb over, go under or get the fence.)

4. Fixed guards must be permanently fixed in position and only be removable with

the aid of a tool.

4

5. Fixed guards must be free of sharp edges and projections and must not themselves

be a harzard.

6. The interlocking guard with guard should be designed so that the guard remains

locked until the guard is closed. The closure of the a deliberate action at the control

station.

7. The interlocking guard with guard should be designed so that the guard remain

locked closed until the risk of injury from the hazard has passed or that the guard

while the robot system is working gives a stop or emergency stop instruction. Where

the hazard cannot be eliminated immediately by power interruption, the interlocking

system must need to include a guard locking or a braking system.

8. When the operator’s entire body can enter the safety protection region (inside the

safety fence) from the door with interlock, install a device so that the door cannot be

closed unintentionally.

9. The interruption, re-establishment after an interruption of fluctuation in whatever

manner of the power supply to the safeguards must not lead to a dangerous situation.

10. Guard and protection devices must cause minimum obstruction to the view of the

production process.

11. Guards and protection devices must enables essential work to be carried out in

installation and/or replacement of tools and also for maintenance by restricting access

only to the area where the work has to be done, if possible without the guard or

protection device having to be dismantled.

12. Re-establishing the interlocked gate or presence sensing device field must not in

itself restart automatic operation.

5

13. A presence sensing device must be installed and arranged so that persons cannot

enter and reach into a hazardous area without activating that device or cannot reach

the restricted space before the hazardous conditions have ceased.

14. Barrier used in conjunction with the presence sensing device may be required to

prevent persons from passing the device.

15. The operation of presence sensing device must not be adversely affected by any

of the environmental conditions for which the system was intended.

16. Resumption of robot motion must require the removal of the sensing field

interruption. This must not be the control to restart automatic operation.

17. Where laser ray equipment or other harmful ray equipment is used, guards and

protection devices must prevent any accidental radiation as well as reflection and

diffusion that may damage health.

AWARENESS MEANS

1. An awareness barrier must be constructed and installed so as to prevent inadvertent

entry into the restricted.

2. An awareness signal device must be constructed and located such that it must

provide a recognizable audible or visual to persons of an approaching or present

hazard.

3. When awareness signal in the form of light are used warn of hazards in the

restricted space, sufficient devices must be used and located so that the lights can be

seen by all persons in the proximity of the space.

4. Audible awareness devices must have a distinctive sound of greater intensity than

the ambient noise level.

6

4.0 PROCESS AND LAYOUT INFORMATION

PROCESS INFORMATION

The seventh FMS-200 station integrates robotics as technology which is

widely used in automated environments. In this case, a robot is used to screw in the

four bolts supplied by the previous station. The robot has a tool attached with a

pneumatic gripper and an electric screwdriver and the station table includes two

warehouses for material (with capacity for 6 lids and 6 shafts in different materials,

colors and heights). These components allow the user to screw the four bolts in the

work in process as well as to carry out operations such as the change in material,

insertion and extraction of material in the assembly and the exchange of material

between warehouses. These applications give way to an extensive range of programs

for the robot's controlling unit thus extending significantly its didactic capacities.

8

THE INTEGRATION OF ROBOTICS

The control of the robot's movements is carried out using a controlling

element which can also be used to program the movements it has to carry out. The

programming is carried out from a PC with the robot's own software.

The station also has a programming console from which the commands must be entered.

9

In order to avoid risks from uncontrolled movements by the robot, the station

is equipped with a protection guard in its programming. We have a wide variety of

robot versions which can be customized to our clients' needs. Consult availability.

HANDLING AND PACKAGING

The packing is designed to protect the modules from physical, chemical or mechanical attack that might be produced during handling and transportation.

For transoceanic transportation, the packaging is treated with waterproofing and dehydrating elements so as to provide protection against the effects of steam, salt spray, dust and other external agents that might damage module components.

Details are given below of the packaging characteristics for each module :

BASE HEIGHT VOLUMESTATION 7 1000 x 700 2010 mm 1.407 m³

When handling, loading and unloading the packaging, it is advisable to employ appropriate equipment such as lift trucks. Once unloaded the stations can be transported by a minimum of two people, while the transfer requires a minimum of four. The boxes must be kept vertical at all times and must, under no circumstances, be piled one on top of another or have other objects placed on top.

When proceeding to unpacking, it is advisable to observe the following procedure :

1. In the first place, make sure there is enough room to carry out the unpacking process. We recommend, as a minimum, that there be a free surface area more than three times the space occupied by each packaging.

2. Next, it is necessary to cut the straps that fasten the four seals at the bottom of the box. These are then raised so as to be able to lift the lid.

3. Two or more people must raised the lid that covers the station and store it where it will not get in the way of the following phases.

4. The next move is to loosen the wood pieces that secure the station to the bottom of the packaging. The best idea is to loosen only the top pieces, as the station can be extracted without freeing all the others: it can also prove useful to keep them for possible transportation in the future. In this operation suitable tools will be required for taking out the coach screws or nails that hold the wood in place.

5. When this operation is complete, the station must be transferred from the base of the packaging on the floor of the space where the unpacking operation is taking place : at least two people are required to do this. It is advisable to check that all the components listed on the station delivery note are included.

15

6. The station has wheels, which means that it can be transported easily and effortlessly to place where it will be used.

INSTALLATION

Individual Station

If there any individual, they come with a tray with a pallet for placing the pieces. In order to avoid problems in the transportation process, the tray with the supporting pallet for the piece to be assembled has been in the position indicated in figure 1.

When installing the station, the tray has to be disassembled so that it can then be placed with the pallet facing upwards, as shown in figure 2.

16

The next step is to proceed to establish the electrical and pneumatic connections for the station. Before doing this we must make that the classroom meets the pneumatic and electrical requirements mentioned above.

For greater safety, it is wise to cut off voltage to the station using the isolating switch on the button pad before any electrical connection is made. This is done by connecting the station plug to the appropriate classroom socket.

In the same way, it is recommendable to carry out the pneumatic connection with the station air tap turned off. A six-diameter pipe must be connected from the classroom socket to the air treatment group intake for the station.

START-UP

STATION 7 (ROBOT) :

1. Carry out a visual inspection of the station to check that there are no elements

that might distort the functioning of the system.

2. Make sure that the fairing protection gates are closed.

3. The robot drive switch at the back of the unit and the magnetic circuit breaker

situated on the electrical control panel must be in the "on" position.

4. Set the cycle switch on the button pad to step-by-step mode.

5. Move the load switch on the button pad to the "on" position.

6. Check that the emergency stop mushroom head on the button pad is unblocked.

7. Press the reset button on the button pad to ensure that the process begins in

start mode conditions. Each time the process is halted, either during start-up or

during a cycle, if the station is not in start mode condition the defect pilot light

on the button pad will start blinking. In addition the drive unit error led lights

up accompanied by the sound of a buzzer.

8. When the start button is pressed the first step in the process will be executed.

Since we will be working in step-by-step mode, it will be necessary to press the

start button each time we wish to take a new step.

9. If any imbalance in the unit is detected, take appropriate corrective action and

repeat the cycle until it functions correctly. It is quite likely that slight

modifications have to be made to the robot's screwing movements so that it

performs its duty correctly. To do this the robot manual must be consulted.

17

10. When the cycle is over, set the cycle switch on the button pad to continuous

mode. When the start button is pressed it will now execute an uninterrupted

cycle.

11. The process can be halted at any time by pressing the stop button or the

emergency stop mushroom head. If the latter is pressed, once it has been

deactivated it will be necessary to return to initial mode conditions (reset

button on the button pad and drive unit). After this we only have to press the

start button on the button pad.

18

PROCEDURE FOR USE

STATION 7 (ROBOT) :

1. Carry out a visual inspection of the station to check that there are no elemens that

might distort the system’s performance.

2. Ensure that the fairing protection gates are closed.

3. The switch at the back of the robot drive unit and the magnetic circuit breaker on

the electrical control panel must be in the ‘ON’ position.

4. Set the cycle switch on the button pad to the desired mode.

5. Move the load switch on the button pad to the ‘ON’ position.

6. Make sure that the emergency stop mushroom head is unblocked.

7. Press the reset button on the button pad to ensure that the process will begin in

starting mode conditions. Each time the process is halted, whether during start-up or

during a cycle, if the station is not in starting mode conditions the defect pilot light

on the button pad will start blinking. In addition the unit’s drive error led will light

up, accompanied by the sound of the buzzer.

8. If the continuous cycle has been selected, when the starter button is pressed the

cycle will be executed. If we are working in step-by-step mode, it will be necessary

to press the starter button each time we wish to perform a new step.

9. The process can be halted at any point by pressing the button or the emergency

stop mushroom. If the mushroom head is pressed, once it has been deactivated it

will be necessary to return to starting mode conditions (reset button on the button

pad and the drive unit). Afterwards it will e sufficient to press the starter button on

the button pad again.
