MIB-100 Special Features
The duration of each inspection interval is determined by the length of time that a particular color appears on the screen and finishes with an audio signal. The duration for each inspection can be altered in 0.1-second increments by the supervisor. The operator simply touches a button on the operator interface to begin the inspection process. The operator interface indicates when the inspection interval has expired by changing color. At the completion of the inspection cycle the inspector can record whether the last sample passed or failed the visual inspection. The PLC will keep the total number of containers Accepted, Rejected and total number of inspections performed. The supervisor can reset the data accumulation at the beginning of a new tray, batch or shift.
Figure 1. MIB-100 Key Components of Production Model
The MIB-100 is fabricated with an anodized aluminum framework and light gray polycarbonate panels. The panels have a dual purpose; first to shroud the inspection samples from ambient light and second to insure the proper background is available for the inspection. All of the components necessary for operation of the manual inspection booth are included as part of the MIB-100 system, including the lighting system, the visual display, the electronic pacer system, incoming and out-going product shelves, adjustable armrest and footrest. The MIB-200 model even has a shelf for a local printer should one be required. The lamps selected for MIB-100 provide approximately 8,000 - 10,000 hours of life in which the intensity maintains an acceptable output level. The standard operating procedure requires that the lamps be changed at least once a year. Normally the lamp change is scheduled during the July or December shutdown period.
In the interest of clarity only selected elements have been shown. The framework is designed so that the shelves and armrests can be adjusted for height of the operator. The Figure legends are 1) Central structure fabricated from extruded aluminum channel sections that accommodate movements of the inspector interface elements, numbers 3, 4 and 5. The height of the inspectors eyes are adjusted to be at the vertical center point of the bottom light and the top light which are not visible in the illustration. Also not shown is the armrest shelf, item 4. The armrest is adjustable up/down and in/out to make the position of the inspection as comfortable as possible. The operator interface panel can be mounted on either the left side or right side of the enclosure opening on the MIB-100 model. Inclined tray support (3) holds containers to be inspected. The tray holder is inclined to position particles in the heel of the container before inspection to avoid the random positioning of particles at or near the containers rotation axis. The input and disposition tray supports can be modified to fit the exact size of the trays used by your organization. For example, some customer may prefer a single tray on the shelves; others prefer two trays on the shelves. No. 5 is the accepted container tray; a cage for rejected containers is positioned across the top of No. 5 or separate "reject box" in mounted below. After function identification has been entered and checked, the color displayed on the face of the TFT flat panel monitor is used to time and control the inspection sequence. The external housing for the operator monitor is labeled (2). The shelf labeled (6) supports a local printer on the MIB-100 model.
Figure 2. Adjustable Shelves and Armrest
The shelves and armrest can be adjusted without the use of tools. Figure 2 above illustrates the adjustment handles used to raise/lower and rotate the shelf support arm. No external tools are required to make the adjustments. When the handles contact the wall or structure simply lift them toward the hex head screw and rotate them to a new position.
There are a number of optional components that can be added to the MIB-100 to aid the inspector and make the inspection task more comfortable.
1) There is a visor kit that is mounted in the front channel of the booth that can be positioned to prevent direct viewing of the lamps when they located in forward most position (higher light intensity).
2) The MIB-100 booth can be raised by using the booth leg extension kit to increase the center line on the inspection area by 12 inches, helpful for tall inspectors.
3) There is an audible alarm option that will provide audible signals for pacing operations as well as the standard LED pacers.
4) The optional Side Shelves Kit is very useful when the MIB-100 is used for high volume production work. The arm are articulated and the joints allow the shelves to be positioned in almost an infinite number of ways. The side shelves are designed to fit the size of the customer holding trays.
5) The Lower Mirror Protection Trays is used to protect the bottom mirror when the operator is inspecting large or heavy containers. The trays holds 1.5 liters of fluid and will prevent protect from entering the inspection booth in the event of an accident.
6) The foot switch option is use to start the inspection cycle in place of touching the operator screen. It is also used to indicate whether the inspection was accepted or rejected when performing Indexed Inspections.
Illumination System Considerations
ILLUMINANCE: (old term: ILLUMINATION)
Definition: (density of luminous flux on a surface)
FC = Lux x .0929
LUX = FC x 10.76 - (ie: 550 FC = 5918 LUX)
