TP 21 – Weighing-bagging machines for preformed valve bags
TP 21 Series weighing-bagging machines for preformed valve bags, suitable for fine powders.
In construction for almost a century, the TP 21 series weighing-bagging machine, successor to the TP 35, is the right machine for weighing and bagging finely ground dry powders.
High performance and minimal maintenance are the key features of this machine, which is also compact and thus easily to include in any context.
Its modularity allows combined configurations of 2, 3 or 4 bagging machines in line.
Weighing is electronic by means of load cells.
Minimal overall size
Dust extraction port
Adjustable-height bag cradle designed to enable filling of bags of variable size
Bearings protected by dustproofing device incorporating compressed air pressurisation circuit
Technical data
HORIZONTAL TURBINE BAGGING SYSTEM
The product is handled by a horizontal turbine, which propels it into the bag.
The device comprises a sturdy external case in special cast iron, with internal rotor (turbine) fitted with easily replaceable steel blades.
It is powdered by an electric motor via a belt and pulley drive.
A special guard ensures that the powder does not come into contact with the bearings.
A pneumatic guillotine damper shuts off the flow of product instantaneously when the weight is reached.
Cleaning is simplified by the total opening of the side cover.

SYSTEM ENGINEERING
TP 21 weighing-bagging machines can be configured individually or in multiple installations (up to 4) in line (see fig. A + B).
The system is automated through combination with the model FB automatic empty bag feeder (see fig. C).

GENERAL CHARACTERISTICS
TYPES OF POWDERS
Dry, finely ground mineral powders (cement, scagliola, plaster, slaked lime, tile adhesives).
VALVE SIZES
STANDARD
The TP 21 Series can be equipped with bagging spouts suitable for valves in the standard sizes 90 mm · 110 mm · 130 mm · 150 mm.
SPECIAL
Spouts for special valve sizes (other than those listed above) are also available on request.
SIZE CHANGE
The same bagging machine can be equipped to fill bags of different sizes.
In this case, tooling the machine takes an estimated “size changeover time” of about 30 minutes (in semi-automatic version).
HOURLY PRODUCTION RATES
The production rate depends on valve size, product type and bag weight.
The graphs illustrate the relationships between these parameters.
ELECTRONIC WEIGHING
Electronic weighing eliminates moving parts, meaning there will be no wear.
The electronic weighing system we manufacture provides instantaneous reading of the actual weight and performs the tare check.
It is type-approved by the notified bodies in accordance with the European MI-006 Directives for automatic weighing instruments.
CS CONTROL UNIT
The model CS (Control System) electronic control unit, connected to the weighing system, provides pre-setting of the weighing phases and the final weight value.
The current weight is displayed immediately.
OPTIONALS
“FLIP-OVER” FULL BAG EJECTION
Full bags are removed via “flip-over” ejection.
For greater production efficiency, once it is full the bag can be removed via optional installation of the device which pneumatically swings the bag cradle.
The bag is ejected onto the removal conveyor belt coaxial with the main belt.
This application is recommended in the following configurations:
Single, Double with operator seated in central position, or Triple or Quadruple when combined with automatic empty bag feeder.
“VERTICAL” FULL BAG EJECTION
Full bags are removed via “vertical” ejection.
In this variant, the bag filler is equipped with “shell plates” which guide the bag during ejection.
The bag is removed bottom-forward, coaxial with the conveyor.
This application is recommended in the both single and multiple configurations with manual empty bag feeding.
BAG VALVE SEALING WITH ULTRASOUND SEALER
ON-BOARD VERSION
Before the full bag is ejected, the bag valve is sealed by an ultrasound sealer which ensures excellent performance even in dusty conditions.
With this application, the bagging machine’s throughput rate is reduced by about 20%.
IN-LINE VERSION
The filled bags are removed to be conveyed, via a bag presser, to the model G853 in-line ultrasound sealer.
AUTOMATIC EMPTY BAG FEEDING
Combination with the model FB automatic feeder automates the bagging machine: the operator has only to oversee the system and keep the empty bag magazine supplied.
INFLATABLE SPOUT TO REDUCE DUST EMISSIONS
This application sharply reduces dust emissions during bag filling.
With this application, the bag must be micro perforated and must also be fitted with a valve (with sealable external collar).
