Hopper Setup#

This section describes the procedure for configuring the hopper. The Hopper is the component that automatically feeds parts to the FlexiBowl® when the level drops below a minimum threshold.

Important

Operating logic

FlexiVision manages the hopper activation logic. It will in fact send the string Hopper;signalnumber;time when it considers activation necessary.

Note

Prerequisites

Before proceeding, make sure that:

  • The Hopper has been mechanically installed

  • The electrical connections have been made (control and power signals)

  • The FlexiBowl® is already connected


Preparing the Physical Setup#

0

Remove the calibration grid and restore the initial layout:

  • Reposition the surface

  • Reposition the central flange

  • Fix the central flange with its four screws


Accessing Hopper configuration#

1

From the software main page, click ../../../_images/tasto_setup1.png

2

On the SETUP page, locate and click the Hopper Setup icon

Setup Page

Setup Page

3

The Hopper configuration page opens


Hopper Setup Interface Overview#

The Hopper Setup page has several sections for configuring the operating parameters of the various hoppers:

Hopper Setup Page

Section

Description

Enable Hopper

Switch to enable/disable the use of the Hopper in the system

Steps

Number of required sequences with which the section of the disc that is currently in the vision area arrives below the hopper unloading area

Time

Duration of hopper activation in milliseconds

Signal

Number of the digital signal used to control the Hopper

Config Hopper

Button to configure the hopper (to be used later)


Hopper configuration#

The hopper configuration allows you to manage the automatic filling of components on the FlexiBowl® disc. The system uses the vision to determine when the filling level is insufficient and to activate the hopper.

Step 1: Accessing the Configuration#

1

Click ../../../_images/tasto_setup1.png. From the Hopper Setup section, you can view and manage the connected load units.

Hopper Setup Page

Hopper Setup Page

2

In the Signal field, enter the number of the digital signal (DO - Digital Output) used to control the Hopper

Warning

It is essential to enter the correct signal number:

  • An incorrect number will activate the wrong signal (potentially dangerous)

  • See the wiring diagram made during installation

  • If in doubt, contact the person who did the wiring

3

Tick the Enable Hopper X box to activate the corresponding hopper.

Important

Only enable the Hopper if the device is correctly installed

4

Click the Config Hopper X button to access the specific configuration

Step 2: Defining the Control Area#

In this step, the portion of the disc that the camera needs to monitor for unloading is defined.

5

Change the blue box on the screen to frame the area where the components will be detected.

Tip

If you have any doubts during configuration, please consult the INFO key on the current page.

Step 3: Definition of Threshold Values#

6

Click ../../../_images/tasto_next.png to access the Define Value Hopper Cam page, where the system learns how to distinguish between an empty and a full disk.

Define Value Hopper Cam Page

7

Remove all components from the vision area and click the first CAPTURE button.

8

Position the minimum number of components you wish to keep in the vision area. If the number drops below this threshold, the hopper will be activated.

9

Click the second CAPTURE button.

10

By clicking ../../../_images/tasto_AUTO.png in the Expression Builder, the system automatically calculates the Mean and Standard Deviation values.

11

Remove some pieces and click ../../../_images/tasto_TEST.png.

12

Look at the result indicator:

  • Green 🟢: Insufficient level, Hopper is activated (unloading necessary)

  • Red 🔴: Sufficient level, Hopper is NOT ACTIVATED (OK)

    Warning

    Insufficient calibration

    If the system does not detect the level correctly:

    Problem: Always green (always activates Hopper) → Threshold too low or interference in the area → Solution: Increase number of pieces in second capture, check that area is clean

    Problem: Always red (never activates Hopper) → Threshold too high or monitoring area not representative → Solution: Reduce number of pieces in second CAPTURE, repeat AUTO

    Problem: Incorrect behaviour (green/red toggle randomly) → Unstable lighting or area too small → Solution: Check stable backlight, enlarge monitoring area, repeat calibration

Note

Hopper Fill Threshold

The Hopper Fill Threshold parameter defines the filling percentage threshold of the vision area below which the hopper is automatically activated.

The value of 100% corresponds to the amount of pieces acquired during the second CAPTURE (full area). Consequently, a 50% threshold corresponds to half of that amount.

The system automatically sets the initial value to 70%, which is a good balance for most applications.

Ongoing modification

It is possible to adjust the threshold without repeating the capture procedure:

  • To unload fewer pieces → reduce the percentage (e.g. 50%) and click AUTO

  • To unload more pieces → increase the percentage (e.g. 85%) and click AUTO

Tip

If you have any doubts during configuration, please consult the INFO key on the current page.

Step 4: Operational Parameters#

Return to the main Hopper Setup screen to define the mechanical behaviour. Hopper Setup Page

Operating Parameters#

Parameter

Description and Procedure

Steps

Number of FlexiBowl® feeds (sequences) required to bring parts from the vision area to the hopper unloading area.

Time

Milliseconds of hopper activation. Recommended value: 100 – 1000 ms (Average: 500 ms). Adjust by ±50 ms according to the desired flow.

Tip

The activation time depends not only on the set value, but also on the volume of components currently in the hopper tank. It is essential to maintain a constant load for an even flow.

Tip

The Time value is closely related to the hopper loading volume:

  • With the hopper full, there will be more parts in the unloading area

  • With the hopper half-full, there will be fewer parts in the unloading area

Important

In general, it is important never to exceed the maximum load of the hopper used.

Saving Configuration#

Warning

Saving recipe mandatory

At the end of the Hopper configuration:

Verify that all parameters are configured correctly:

  • Monitoring area positioned

  • Thresholds calibrated (TEST working)

  • Steps and Time set

Return to the main page ../../../_images/tasto_recipes.png

Click ../../../_images/tasto_save_recipes.png

Confirm saving

IMPORTANT: Any changes made are stored ONLY if the recipe is saved correctly before exiting or changing page.

Without saving, all Hopper setups will be lost when FlexiVision One is closed!
