SECTION 3 : DESCRIPTIVE MACHINE SPECIFICATIONS
3.1 MAIN MACHINE UNIT
3.1.1 Cutting Unit : This is the last and the final operating unit which cut down the plastic film after it had been sealed and cooled thoroughly from the centre and side thereby leaving one of the opening for filling. This assembly constitutes two blades adjusted at an angle Blade 1 and 2 having a scissors cutting operation.
3.1.2 Front Cooling Station : This station is provided by means of press type cooling arrangement for a proper and smooth surface finish of the side sealing which has just been done by means of the side sealing units. This front cooling station is fixed with a upper station which is mounted by the spring on the top and nuts on the lower position of upper station. The pressure of the cooling unit can be adjusted according to the type of plastic film and sealing temperature by means of this spring and the position can be adjusted by means of the nuts. This cooling station can be moved to and for by means of rack and pinion arrangement. The cooling water required is about 8 L - 15 L (max.) coming from the chilling plant.
3.1.3 Front Sealing Station : This station is divided into the front sealing station No. 1 (Heater No.1) and the front sealing station No.2 (Heater No.2). The front sealing station having a sealer on the lower side, which seal the plastic film from the lower portion. This sealer can be changed according to the sealing width as accordingly demanded. The sealing station No.2 having a sealer from the upper portion seals the film from the upward sides. The position and movement of the station can be accordingly done as discussed above. The next main unit of this machine is the unwind unit of this machine is the unwind unit which unwinds the laminated sheets in the roller form.
3.1.4 Photocell Station : This station is placed just behind the front pull roller. This constituted a photocell, which serves out the colour combination and directs the accurate cutting at a very high speed. The photocell is made to sense a colour mark on the film.
3.1.5 Bit Sealing Station : This assembly oriented before the front, sealing assembly constitutes of bit sealer used in âpart sealing at the edge of the filmâ while stand up pouches. The common size of the Bit sealer are (LxW) = 10x80, 10x100, 12x80, 12x100, 14x80, 14x100, 15x80, 15x100 etc.
3.1.6 V Notching Station : This station performs the operation of Notching mark on the pouch, which requires for tear up the filled pouch. This station incorporated of a pneumatic actuator, which reciprocates the hardened notching tool thru the film thickness. The maximum frequency of this unit is 100 stroke/ Min.
3.1.7. Pneumatic Punching Unit : This station incorporate of a punch and die set driven by a pneumatic actuator which makes the punches on the film.
The punching on the centre seal pouch is required for the carrying purpose. The die & punch set has a touch of Uflexibility in various shape & sizes i.e. round, square, oval, UFO shape etc.
3.1.8 Rear Cooling Station : These cooling station has got the same function as the front cooling station do for the side sealing but they are incorporated for the centre sealing which has just been done by the rear sealing station. The setting of pressure and adjustment of the stations can be done as discussed above.
3.1.9 Rear Sealing Station (Radius Sealing) : The rear sealing station is the main unit which starts sealing the laminated film parallel to the flow by sealing radially. The radius sealing is responsible for the stand up pouch, semi stand up pouch and the zipper sealing on the upper & lower layer of the film. This is one of the main sealing station on the machine. The station has 4 pair of sealing set which compressed on each other by the Rocker Arm drive in between which both the layer of the film flows.
3.1.10 Main Drive Assembly : This assembly constitutes the Cam-follower mechanism linked by a sprocket chain drive which is further driven by 5 HP III phase induction motor with a warm reducer of ratio 1:30.
The Cam-follower assembly further gives drive to the Rocker Arm assembly which directs the reciprocating motion of all the stations.
3.1.11 Miscellaneous Assemblies :
a. Slitting Assembly - The slitting assembly is oriented before the cutting unit which provides the parallel tearing of the film by means of Razor blades on the flow of film. These assembly is used for the multiple pouch production per shot.
b. Pinch Roller Assembly - This assembly is oriented after the horizontal dancing unit and constitutes of 2 parallel rubber roller with a fixed gap in between them. The pinch roller controls the web of both the layer of film flow.
c. Lubrication Network - This is an oil pipe line network which is initially connected to the piston pump of 10 CC/stroke, which provides the lubrication to the all Cam- follower assemblies.
3.2 UNWIND UNIT
1. A vertical Unwind is used for this machine, which incorporates the Electro magnetic powder break of 2.5kg. torque and a 1 HP A.C. induction motor with inverter with a warm reducer for the film unwinding operation. Also there is a vertical dancing unit for the constant tension and the feeding of the film. A 1000 wide film roll can be installed on this unwinder.
2. A fourth Unwind is used for the additional film roll mounting which also has a vertical mounting.
A vertical dancing lever unit is also incorporated with the Unwind unit. The film feeding on the dancing lever is controlled by a 1 K. Ohms potentiometer which generates the feeding thru the A.C. derive the body of the unwinder is fabricated.
3. Two nos. of vertical side Unwind unit which are driven by a 1 HP Induction motor with a inverter is also incorporated with this Unwind. This Unwind is for the mounting of bottom strip roll of width range 30 mm - 300 mm.
4. A âMâ� shape former is used for changing the angle of flow of film to 90 deg. & parted the film in two equal layers by a Razor blade slitting assembly.
5. Copper Roller Assembly is provided for the web control of the upper & lower film and to shift the film perpendicularly to the flow.
6. Chain Pulley Assembly is provided on the Unwinder for the loading/unloading of the film roll upto the weight of 0.5 ton. A manually operated hoist is used for the lifting.
7. Adjustable Former Assembly is provided for the folding and controlling the flow of bottom film.
3.3 HORIZONTAL DANCING UNIT
The Horizontal Dancing Unit is oriented between the main machine & the Unwind unit. This unit provides a constant tension and feed to the flow of both the layers of the film separately. This unit consists of a pair of dancing roller, which reciprocates up & down and hence gives a constant feeding to the film and controlled by 1 ohm Potentiometer that controls the speed of Unwinding Motor. The Dancing Arms are connected by 2 Pneumatic actuators of 40 bore - 200 strokes.
3.4 OPTIONAL ASSEMBLIES
3.4.1 Scrap Winding Machine : This machine is used for the winding of side web which is parted by the slitting unit from the main film. This machine is driven by a 1/2 HP induction motor and can be placed anywhere near the main machine.
3.4.2 Gusset Folding Assembly: This is a new concept in the pouch manufacturing industries by which we developed a âbottom folded gusset pouchâ�. These pouches can intake a greater amount of filler with respect to the conventional three-side seal pouch. The gusset assembly is incorporated by the two circular angular discs on the one side of the film (which is in the single layer). The position of the gusset disc can be adjusted in X & Y axis by means of the knobs provided on the mountings
3.4.3 D-Punch Attachment Assembly: This is a separate unit which can be mounted on the main machine. This unit is controlled by a separate PLC and all the motions are pneumatically generated. Various nos. of Pneumatic actuators and vacuum generators are used in this unit.
