Referring to Figure 1 & 2, an embodiment of the present invention a machine for preparing a flower pot type of firecrackers multi-position rotating turret (2) with pockets (3) to hold the filling cones (4) on a cone holder (5) automatic filling machine, which has a bearing housing (8), pneumatic cylinder (10), a rotating shaft (6) fitted on the plate (7) of base frame; the lower end of the shaft is fitted on bearing which are fixed in bearing housing (8) and upper end of the shaft is fitted with covers on top, which are fastened with the turret (2); at bottom of shaft, uni direction unit (9) is fitted which is fixed with a pneumatic cylinder (10); every forward stroke of cylinder makes the shaft to rotate according the stroke length and rotates the turret; the top and sides of the disc has a solid chassis with the vertical axis, connected with a feed hopper, the bottom side of the hopper has a filling valve with pneumatic actuation; there is an empty cardboard cone on rotating turret (2) within pockets (3); turret rotates brings the cone from one station to another individual working stations for filling, washer placing, ramming.

A Machine for preparing a flower pot type of firecrackers consists of a base frame (1) made of aluminium pipes and sheets. There is a rotating turret (2) with pockets (3) on it, to hold the filling cones (4). Further, in order to make machine suitable for different size of cones, a cone holder (5) is fitted in turret holes which can be changed to suit new cone diameter. Individual working stations are made for filling, washer placing, ramming and above all operations, which are described below:

In an embodiment of the present invention turret (2) positioning comprises movement of the turret at intermittent speed from one station to another station; it stop at all station for fixed time; a rotating shaft (6) assembly has been fitted on the plate (7) of base frame to rotate turret (2) positioning. The shaft is further fitted on bearing which are fixed in bearing housing (8). The shaft is further fitted with covers on top, which are fastened with the turret (2). So, rotation of shaft makes the turret also to rotate. At bottom of shaft, uni direction unit (9) is fitted which is fixed with a pneumatic cylinder (10). Every forward stroke of cylinder makes the shaft to rotate according the stroke length and in turn rotates the turret. This brings the cone from one station to another. The return stroke of cylinder is empty.

By adopting the technical program automatically fireworks safety, the ingredients placed in the cones (4), fireworks will need premixed ingredients of gunpowder into the cones (4), starting rotation the shaft fitted on bearing which are fixed in bearing housing (8). The shafts are fastened with the turret (2). So, rotation of shaft makes the turret also to rotate. At bottom of shaft, uni direction unit (9) is fitted which is fixed with a pneumatic cylinder (10) with telescopic cylinders driven to rotate, the power source driving the rotating shaft driven turret (2).

A pneumatic firecrackers machine for preparing a flower pot, which includes frame and cylinder, characterized by further comprising: frame (1) made of aluminium pipes and sheets; a rotating turret (2) with pockets (3) on it, to hold the filling cones (4). Further, in order to make machine suitable for different size of cones, a cone holder (5) is fitted in turret holes, pneumatic cylinder (10) with telescopic cylinders pushing the block and the cylinder head and piston rod connected to a fixed connection to rotating shaft (6) respectively, with the driving gear is coupled to the bearing means for rotating turret (2).

A PLC (25) is programmed to have information about interlocks, time and feedback system.

Empty cones (4) are placed manually by the operator in the rotating turret (2) with pockets (3) on it, to hold the filling cones (4) prescribed pocket on cone holder (5). Optionally cones (4) are placed or can be placed using pneumatic pick and place arrangement or similar other means.

Empty cones (4) are filled with firecracker material powder through filling valve (11) with pneumatic actuation has been used, which has all contact exposed parts are rubber covered to suit fireworks requirement. This eliminates rubbing using non approved material. There is a hopper (12), in which the powder is filled and valve is fitted below it. After getting signal, the valve opens and the powder falls in the cone. The amount of powder is decided by the opening time of valve and valve opening diameter.

First Washer Placement: In order to prevent any external moisture going inside the filled powder, the cone has to be covered by washer (13) on it. The washer placing station comprises of rotating pin sprocket (14) uniquely designed to suit the washer picking requirement. The washer picking plate (15) is fitted on rotating shaft (16) which rotates and goes up to pick the washer stacked on top. A vacuum unit (17) is mounted on plate which picks the washer and places it down. The pins (18) of sprocket are mounted on pneumatic cylinder.

First washer ramming station consists of a ramming bar (19) designed and dimensioned to meet the washer diameter and cone overall dimension is fitted on pneumatic cylinder (20) and pushed forward to exert ramming force on washer.

Second washer placement: In order to have ensured sealing of filled powder, second washer is placed just above to first washer. The second washer placing station comprises of rotating pin sprocket (14) uniquely designed to suit the washer picking requirement. The washer picking plate (15) is fitted on rotating shaft (16) which rotates and goes up to pick the washer stacked on top. A vacuum unit (17) is mounted on plate which picks the washer and places it down. The pins (18) of sprocket are mounted on pneumatic cylinder.

Second washer ramming station consists of a ramming bar (19) designed and dimensioned to meet the washer diameter and cone overall dimension is fitted on pneumatic cylinder (20) and pushed forward to exert ramming force on washer.

In order to seal the cone and add required weight, mud with suitable chemical and other liquid is applied on cone. Similar to powder filling, mud filling valve has been fitted and based on time, it is applied in the cone. Mud spreading bar (21) is formed and it spread the mud on periphery.

Cone discharging from machine: The filled cone is lifted by discharge rod (22) and it lifts the cone from the turret. The lifted cone is thrown out by a whisper of air (23). The thrown cone is further collected in bin.
