2.6.2 Detachable Material Hopper Procedure
Detachable material hopper for TB45 (4 bins) TB100 (2 bins) and
TB250R-4 (2 bins) models.
NOTE
All detachable material hoppers on the above referenced models are held in place
with a captive retainer (screw) held in the hopper support frame. The retainer
stabilizes the detachable hopper when mounted in the blender support frame from
forces exerted on the hopper by resin weight and various types of automatic
loading/receiving device(s) during normal vibration from the process. There is a
separate retainer for each detachable hopper.
When removing any of these detachable hoppers for cleaning or material
changeover; first, remove the automatic loading/receiving device; then use the
proper hex head socket or screwdriver and back out the captive retainer. Hopper
can then be removed.
Upon re-insertion of the detachable hopper, it is very important to re-anchor
the respective hopper(s) using the captive retainer to provide stability
during normal operation of the blender. Once the hoppers have been placed
and anchored, the respective loading / receiving devices can be mounted.

Structure and Function
5.2 Brief description of the functional units
(Item numbers refer to diagram on previous page)
The TrueBlend meters and mixes free-flowing plastic granulate (regrind and
natural material) and additives. The unit mixes four to six materials, depending on
model and configuration.
For example, the unit has four material hoppers [2] with mounting flanges for one
hopper loader
cone valves [4] and are fed to the weigh bin [13], which is mounted on a load
cell [11]. The pneumatic cylinder [12] opens the weigh bin.
The mixture (batch) [5] falls into the mixing chamber [10] and is mixed by an electrically powered mixer [8]. The mixing chamber holds three batches. After mixing
the batch [9] the mixing chamber is emptied by the pneumatic discharge slide
gate (remote mount) [7]. Approximately one batch remains in the mixing chamber
to ensure that the next batch can be optimally mixed.
The operation of the TrueBlend is by a PLC controller. The controller receives a
signal to feed material from the capacitive level sensor [6] in the mixing chamber
(see also 9.5.1 Adjust or replace level sensor

5.4 Operating modes
The TrueBlend operates in three different operating modes:
• Gravimetric mode: all components are metered and weighed in sequence.
• Volumetric mode: all components are metered in sequence without weigh-
ing.
•Combined mode: a gravimetric cycle is followed by an adjustable number
of volumetric cycles.
38 Edition: February 2007
TrueBlend™ Structure and Function
5.4.1 Gravimetric mode
The metering sequence is identical as outlined below with every metering cycle
unless Precision Additive™ (PREC) is selected:
1 The regrind is metered by the vertical cone valve as a percentage of the
whole batch and fed into the weigh bin.
2 The required quantity of natural material is calculated by the controller and
dispensed as the next component.
3 The additive natural (Add N) is metered as percentage of the natural mate-
rial(s).
4 The additive batch (Add B) is metered as a percentage of the total batch.
The remainder of the cycle is the same with all operating modes and is described
in
5.2 Brief description of the functional units.
5 Precision Additive™ applies to a low percentage (<2%) color or additive
natural material which is a critical component of the process. The Precision Additive can only be applied to one additive natural position. When
selected that material is dispensed before the natural material, but after
regrind if being used. The Precision Additive™ is dispensed and weighed.
Then the natural material is dispensed and adjusted for any minor variation with the Precision Additive™ to assure the proper ratio; thereby, assuring this critical component is held to the actual target setting. Then the
balance (if selected) of additive naturals are dispensed to their setpoint
percentages of the weighted naturals, followed by any additive batch components.
5.4.2 Volumetric mode
Volumetric mode is an emergency mode and must only be used if the weighing
system fails or in special circumstances.
The metering sequence is identical with every metering cycle.
1 First the regrind, then the virgin material is metered through the respective
vertical valves by time control and filled into the weigh bin. The load cell
does not operate in volumetric mode.
2 The additives/batch and additive color are added last through the smaller
vertical valves by time control.
The remainder of the cycle is the same with all operating modes and is described
in
5.2 Brief description of the functional units.
5.4.3 Combined mode
In combined mode one gravimetric cycle is followed by up to eight volumetric
cycles (number is adjustable). The total material throughput can be increased by
eliminating the weighing times. The metering cycle is described in
5.4.1 Gravimetric mode.

changed in the majority of cases. Please consult with Conair service before you
change any of these parameters.
A. Settling times
Edition: February 2007 75
Operation
TrueBlend™
The settling time is the time after a component dispensed into the weigh bin, while
multiple weight reading are taken. (This time allows the material to settle and the
load cells to recover from the dumping process before the final weight reading is
taken.) The time should be entered in milliseconds For example, in the above
screen shot 1500 milliseconds is entered which equals 1.5 seconds. For most
Trueblend applications the default time of 1500 milliseconds should be
acceptable. In retrofit applications where slow screw feeders are used these times
may need to be increased to allow the material to drop from the feeders.
B. Batch times
Batch Settling time – The Batch settling time is the time prior to beginning a
batch, where the blender waits for the weigh bin to settle and return to the tare
weight.
Weigh Bin Open time – The weigh bin open time is the time that the weigh bin is
actually open as the material is dumped into the mixing chamber.
Second Dump time – The second dump time is the length of time that the weigh
bin opens a second time to knock off any additional material that may remain in
the weigh bin. This feature is used on the TB45 and TB100 blenders.
Flow Control Valve time – The flow valve time is the time that the material valve
under the mixing chamber is open to allow the material to exit the mixing
chamber. (When this option is included)
76 Edition: February 2007
TrueBlend™ Operation
Batch time screen – The “Start %” refers to the size of the first 7 batches. The
blender reduces the batch size of the first seven batches to avoid overfilling the
weigh bin before the correct flow rate is known. The default is 50%, but when the
target weight is only a few grams of any component, 50% is difficult to achieve
and often results in alarms.
Extrusion Mode button – The extrusion mode button, when selected,
ensures that the blender will only run if all components add up to between
99 and 101%. A warning hand will be displayed above the ON/OFF button to
prevent starting. If the percentages are changed while the blender is running, a
warning message will be displayed and the blender will stop the current process.
NOTE
NOTE
When in Extrusion Mode do not change the recipe while the blender is
operating..
When operating in “Extrusion Mode” it is also important that all material
positions be set as the same material type, “Naturals” (N).
This will ensure proper ratios of the ingredients are maintained and the
“Alarm” mode (selectable from the component setup screen) be set to “Stop”.

C. Dosing Rates
The Dosing rates are the flow rates in gm/sec of each component in the mix. This
is the same value as is displayed on the individual component screens. In normal
operation the dosing rate starts with a default value and the default value is
modified by the blender software during a material calibration, or as blending
progresses, to reflect the actual material flow rate seen for each component.

Detachable material hopper for TB45 (4 bins) and TB100 (2 bins) models,
and TB250R (2 bins).
NOTE
All detachable material hoppers on the above referenced models are held in place
with a captive retainer (screw) held in the hopper support frame. The retainer
stabilizes the detachable hopper when mounted in the blender support frame from
forces exerted on the hopper by resin weight and various types of automatic
loading/receiving device(s) during normal vibration from the process. There is a
separate retainer for each detachable hopper.
When removing any of these detachable hoppers for cleaning or material
changeover; first, remove the automatic loading/receiving device; then use the
proper hex head socket or screwdriver and back out the captive retainer. Hopper
can then be removed.
Upon re-insertion of the detachable hopper, it is very important to re-anchor
the respective hopper(s) using the captive retainer to provide stability
during normal operation of the blender. Once the hoppers have been placed
and anchored, the respective loading / receiving devices can be mounted.
