Transport and unloading of the machine: Given the fragility of some components of the machine, it needs a wooden crate with reinforced platform for attachment to the base by bolts in the holes of the rubber feet.

With the aim of keeping the weight well balanced, we recommend moving the die head halfway before packing the machine up. In case of maritime transport, the linear guides and the driving spindle located in the lower section of the cutting head need to be lubricated and totally covered with a plastic sheet. We will place the four rubber feet and level the machine.

During the punching process, we can STOP the machine pressing on red button STOP and we can open the doors. In this way, we can restart the process keeping the values pressing START once doors are closed again. On the screen we can see how far the belt has progressed, the position of the cutting head and the number of rows punched.

MANUAL: In the Manual Mode, we can execute a punching test to adjust the pressure or the cutting time. To this purpose, we will feed the machine with a sample of the same material and, with the door closed, press on the PUNCH CYL.

The cylinder will operate with the gauge pressure and the punching time set in the configuration in PARAMETERS screen.

To work with any of these memories, simply click on LOAD once you see the memory on the screen; you can also modify the memory and save it with a different name. To erase an existing memory, click on DELETE. REMARK: To save a memory, we need to assign a name to it.

Configuration:

In the Configuration Menu, we can see and modify some parameters, depending on the work we want to execute. These parameters always keep memorized until changed again.

Vacuum interval: time in seconds between vacuum works Time: time in seconds during which the vacuum will activate

REMARK: These vacuum times shall be adjusted depending on the punching hole diameter and its frequency.

- Table time movement



Model: PAF-300

20



After completing each row, the nylon table will move some millimeters depending on this time set. This table movement makes cutting easier and ensures a homogenous wear of the table. This time will usually last 0.3 to 0.5 seconds.

- Punching time This is the time during which the solenoid of the die is activated. It shall be adjusted depending on the thickness of the material and the punching pressure.

- End belt action Not step correction: For open belts without end rows adjustment. Step correction:

For endless belts to reprogram the last row distance and row number, for this reason we have to program less rows that really needed to adjust the last rows when appears this screen.

Them, we can introduce the new value in C1 distance between rows and NC row number and press ENTER with this new value, the machine continues work to end the belt with this last values. Also you can modify this values again, touching the down right corner of screen.



Model: PAF-300

21



- End belt measure forward The progress in millimeters of the belt when a program or a sequence has been completed.

- Lot. Number Number of series that will be made automatically with End belt measure between series.

Preparation:

To start a job, introduce the end of the belt to be punched on the right side of the machine, passing the belt below the hold-down bar. REMARK: DO NOT MOVE the left guide position, “0” point of step motor is aligned with this reference. Ensure that the belt is properly placed on the wheel of the measurement encoder, completely tangential to the left guide of the table up to the drive rollers. You can adjust the height wheel pressure depending the belt thickness.



Model: PAF-300

22



Once the initial end has been introduced, adjust the two right guides to prevent the material from suffering any displacement.

Lower the pressure role with the black button of frontal panel to get it fixed, allowing belt progress in automated mode.

If we want to adjust the top roller pressure, you can do it with pressure regulator (see picture)



Model: PAF-300

23



If we have a starting reference, we will operate in MANUAL mode to advance or rewind the belt to the desired extent; then execute a ENCODER RESET to put the gauge to “0”. REMARK: To pass the belt below the hold-down bar, the machine needs to be reset with the blue button of the control panel.

Die change: To change the diameter for another with a different diameter, we recommend to move the punching head to the opposite side some centimeters to facilitate space. Select MENU in MANUAL and pressing right STEP MOTOR button to move.

Open the protection door. Also, when door is opened, we recommend to active vacuum system during this die change to avoid debris from falling from the head onto the belt.
