TabXpress PUV 20 GMP MODEL

HIGH SPEED CENTRAL DRIVE PRECOMPRESSION ROTARY TABLET PRESS       

                

PUV20

 

 

PRISM TabXpress PUV is a high speed single sided central drive Precompression Rotary Tablet Press suitable for medium batch size production.

 

TabXpress PUV designed in an effort to exceed the highest cGMP requirement and to ensure the most economical and efficient tablet production. The new PRISM TabXpress PUV features a unique ergonomic design for EASY to Operate, EASY to Fast Changeover, EASY to Clean with minimum down time. The TabXPress Tablet Press is completely separated into three zones i.e. Tablet Compression zone, Machine service zone and Electrical controls zone. The Optional feature of TabXPress-V-II machine can provide with Touch Screen Operate Interface with PLC Controls, which is mounted in a separate electric controls cabinet.

The TabXpress PUV Tablet Press is offered in four different models viz. Tooling 20 Stn “D” Type, 27 Stn “B” Type, 30 Stn “BB” Type.

 

THE MACHINE CONCEPT:

The basic construction of the machine consists of:

  • Base frame with Stainless steel covering drive Zone.
  • Tablet Compression Zone.
  • Electric Controls Zone.

THE ERGONOMICS DESIGN:

The TabXpress PUV has been completely newly designed according to the most modern ergonomics aspects.

  • cGMP confirms.
  • Fast cleaning and changeover capability.
  • Totally enclosed central drive.
  • Pre-Compression system to improve compressibility.
  • Force feed systems will bottom drive for uniform filling to weight consistency.
  • Powder level sensor to ensure quality production.
  • Option: PLC Controllers with MMI Touch screen interface controls.
  • Easy to operate and maintenances.
  • Adjustable upper punch penetrates.
  • Lower punch scraper seal.

 

THE DRIVE:

The machine is equipped with frequency controlled drive. A large torque can be achieved even at low speed and because of its high regulating speed. The turret is centrally driven by an electric motor with electromagnetic clutch, through rigid reduction gear box. The electromagnetic clutch is installed to protect the electric motor and machine.

THE FEEDER SYSTEMS:

The tablet press has wide variety of applications that the large number of materials to be pressed in tablet shape has different characteristics therefore PRISM TabXPress PUV has developed different types of feeder systems ranging from a simple gravity feeder to complex forced including the possibility of constant level feeders. The feeder motor is installed in separate machine drive zone with variable frequency controlled to ensure high exception of tablet weight consistency through feeding performance of powder in high speed of the machine. The design of the feeder has been easy to remove and repositioning without any tools. It is fitted with butterfly valve for flow controls of powder and powder discharge chute to empty the feeder.

THE COMPRESSION ROLLER STATION:

The machine is equipped with two completely new designed compression Roller Station for pre and main compression.

THE PRE COMPRESSION:

PRISM TabXPress PUV is facilitated with Pre-Compression station. The Pre Compression helps air leave from the granules in the die and also pre-densities the material prior to the main compression as well as improves the finishing quality of tablet. This feature is especially useful when the tendency of material for capping and lamination is greater.

THE MAIN COMPRESSION:

Main Compression has been designed with large diameter rollers to ensure optimum dwell time for the punches under pressure and therefore a tablet is getting good hardness.

THE UPPER PUNCH PENETRATION:

Adjustable upper punch penetration is incorporated as standard feature of the machine. The feature allows changing the level of compression zone in the die. It is beneficial while tabletting difficult products or very shallow tablets. The system also reduces ejection loads and extends punch head and ejection cam life.

THE TAKE OFF SYSTEMS:  

Moving parts before sintering when they are still fragile is a delicate look. Removing them from the press requires specific handling systems PRISM TabXPress designs specific needs of any shape tablet with easy shifting and removing.

THE TURRET AND DIE TABLET:

PRISM TabXPress is proposing a S.G. Iron Steel.

THE LOWER PUNCH SEAL:

Punch tightness can cause severe damage to the press. The lower punch guide is protected by scraper seals which minimize the possibility of tight lower punches caused by the possible ingress of powder in to the punch guide holes. This results in reduced wear and extended tool life and enables the machine to run for longer periods between clean downs.

THE CAMS:

For smooth operation, all cams are calculated by computer with a harmonic profile to fluent operation and less wear. The upper cam plate designed with single piece cam plate with track for smooth running.

THE PRESSURE LOADING AND OVERLOAD RELEASE:

The hydraulic power pack is a unique way of applying compression force. It combines the advantages of selecting constant force or constant thickness of the tablet. The overload release ensures any overloading transmitted to the punches.

THE FAST AND EASYTOOL CHANGE OVER:

PRISM TabXpress PUV designed with features to facilitate Fast Tool Change over through easily removable inter locked weight adjusting section for fast and easy removing and fitting of lower punch and die. Thus, minimizing downtime of the machine. The hand wheel is situated at gearbox with protection cover and indexing rotating arrow.

THE CLEANLINESS AND CLEANBILITY:

The Tabletting zone has no painted surface and corners to avoid dust traps. The large cabinet combined with acrylic guards gives excellent access area for cleaning. Dust extraction nozzle significantly reduces the dust levels in the tabletting zone. The turret fitted with lower punch scrapper seals for preventing the powder from passing through lower punch guide in to the Cam Track and Lower Roll. This results in reducing downtime between clean periods of the machine running. Also reducing wear and tear of Cam Track and extended tool life.

THE DUST EXTRACTION SYSTEM

In High Speed Tabletting, dust extraction is essential. The dust suction nozzles are fitted at compression point with quick release design.

THE CONTROLS

The electric control panel of the machine is situated at the front of the machine. The PLC Touch screen Control Panel can be supplied as optional to replace electric controls. All the tablets parameter i.e. weight adjustment, pre-compression tablet thickness and final tablet thickness are precisely controlled with accurate dials. As all the controls are located outside and front of the machine the can be operated when machine is running. This simplifies the machine setting.

THE OPERATOR SAFETY

The front side fitted control panel allows easy and safety adjustment of operating parameters and highlights the operator with warning lights and signals. To emergency stop buttons are provided to stop the machine immediately. All upper guards are fitted with interlock switch with visual warning light at control panel to ensure that the machine is nit operated when the guards are in open condition.

THE NOISE LEVEL

The compression area is completely encapsulated and the machine itself is surrounded by sound absorbing covering. Therefore, the noise level is below 75db even under highest load. The machine is mounted on anti vibration mounts.
