Inside the forearm 5 at the exit from it on the axis 7 (see Fig. 4), a shutter 8 is fixed with the possibility of its rotation by means of pneumatic cylinders 9 and cranks 10 to the “OPEN” and “CLOSED” positions. The pneumatic cylinders 9 are mounted on brackets 11 mounted on the outer surface of the pin 5. The pneumatic cylinders 9 are closed by a casing 12. The nozzle 6 has channels 13 inside (see FIG. 4) for venting, and the outside has a conical surface 14.

The supporting device for the polymer shell is made in the form of a rod 15 mounted on the frame 1, on which a pneumatic cylinder 16 is fixed (see Fig. 3), the rod of which is equipped with a pivoting lever 17 carrying a cage 18 with a brake ring 19

the shell 20, for example polyethylene, to the conical surface 14 of the nozzle 6.

The operation of the shutter 8 is synchronized with the operation of the metering device 4 by a pneumatic control system (not shown).

The sealing unit of the ends of the shell (see figure 1) contains a table-stop 21, designed to set the required length of the cartridge, and a locking device, made, for example, in the form of a clipper 22, for example, "Clipper pneumatic brand Corundum clip 2.0- 3.0 "and intended for pinching the polyethylene sheath 20 by applying two clips 23 to it, and segments with a knife (not shown) of the formed cartridge 24. On the guides 25 of the clipper 22, pushers 26 with springs 27 for feeding clips 23 are installed.

The pneumatic control system (not shown) is equipped with two control panels 28 and 29 mounted, respectively, on the clipper 22 (see figure 2) and on the frame 1 (see figure 1), as well as the preparation unit 30 mounted on the frame 1 air (see figure 1), intended for the purification of compressed air from impurities, sludge condensate and pressure regulation.

On the control panel 29 (see Fig. 1), a pinch toggle switch 31, a button 32 for controlling a knife (not shown) of the clipper 22, and a button 33 for controlling the metering device 4 are fixed.

On the control panel 28 (see figure 2) placed switches and controllers of the installation, namely:

- switch 34, designed to set modes (automatic or manual) control the dosing device 4;

- timer 35, designed to set the operating time of the metering device 4;

- a toggle switch 36, turning on and off the preload of the brake ring 19 of the supporting device of the polymer shell to the pin 5;

- regulator 37, designed to change the preload of the brake ring 19.

Pressure pipe 38 connects pump 3 to metering device 4. Drain pipe 39 serves to return explosive from metering device 4 to hopper 2.

The metering device 4 is designed to supply explosive from the pressure pipe 38 to the pin 5 and shut off the drain pipe 39 when the metering device 4 is turned on.

Installation for patronizing explosives works as follows:

Installation can work in two modes: manual and automatic.

Manual mode is implemented as follows.

The operator manually slides the pivoting lever 17 down and rotates it through an angle, which provides the operator with the subsequent unhindered clothing of the plastic shell 20 on the casing 12, mounted on the pin 5.

Then the operator manually installs in two guides 25 of the clipper 22 cassettes with clips 23, which are sent to the receiving stores (not shown) of the clipper 22 with pushers 26 by means of springs 27.

At this time, from the mixer (not shown in FIG.), The hopper 2 is filled with explosive.

Then, the operator through the block 30 by supplying compressed air to a control system, for example, pneumatic (not shown in Fig.), Turns on pump 3, and also orientates all units of the system operating synchronously, such as shutter 8, dispenser 4, and clip clamping mechanism (on Fig. not shown), pushers 26 and a knife (not shown) of the clipper 22.

In this case, the shutter 8 is set to the position "CLOSED".

In this case, the pump 3 captures the explosive from the hopper 2 and delivers it to the metering device 4, which in the initial position directs the flow of the explosive through the drain pipe 39 back to the hopper 2.

Then, the mode switch 34 is set by the operator to the "Manual" position, and the pinch toggle switch 36 to the "Off" position.

In this case, the brake ring 19 with the help of the pneumatic cylinder 16 extends down, releasing the polyethylene shell 20, pinched from one (lower) end.

Further, the plastic shell 20 unfilled with explosive material is manually moved down to the table - stop 21, and the pinch switch 36 is set by the operator to the “On” position, while the brake ring 19 is pulled up using the pneumatic cylinder 16, pressing the plastic shell 20 against the conical surface 14 of the nozzle 6.

By manually pressing and holding the control button 33 of the metering device 4. the operator sends a signal to the pneumatic control system (not shown in Fig.) To turn on the metering device 4, which shuts off the supply of explosive through the drain pipe 39 to the hopper 2 and directs it to the pin 5.

In this case, synchronously with the inclusion of the metering device 4, the shutter 8 with the help of pneumatic cylinders 9 and cranks 10 is set to the "Open" position ie along the longitudinal axis of the pin 5. An explosive fills the polyethylene shell 20, forcing air out of it through the channels 13 until the control button 33 of the metering device 4 is held by the operator.

After filling the polyethylene shell 20 to the desired mass (determined by the operator visually by the position of the polyethylene shell relative to the table - stop 21), the operator releases the button 33 for controlling the metering device 4.

In this case, the metering device 4 again transfers the flow of explosive into the drainage pipe 39, and the shutter 8 is set to the "Closed" position.

Then the operator by the pinch toggle switch 31 sends a signal to the control system to turn on the clipper 22, which pinches the polyethylene sheath 20 and puts two clips 23 on it.

Then, with the knife control button 32 (not shown in FIG.) Of the clipper 22, the operator turns on the clipper 22 (not shown) of the clipper 22 and the finished cartridge 24 is separated from the pin 5.

The cycle is repeated to obtain the next cartridge.

Automatic operation is implemented as follows:

In the automatic mode of operation, the switch 34, designed to set the modes (automatic or manual) control the dosing device 4, is set by the operator in the "Automatic" position.

Using the timer 35, designed to set the operating time of the metering device 4, the filling time of the cartridge 24 is regulated, which will correspond to the required size (weight) of the cartridge 24.

The timer 35 is turned on by briefly pressing the button 33 to control the metering device 4.

In this case, the metering device 4 is turned on, blocking the supply of explosive from the drainage pipe 39 and directing it to the pin 5.

After filling the polyethylene shell 20 to the desired mass, determined by the setting of the timer 35, the metering device 4 automatically shuts off the supply of explosive to the pin 5 and sends it to the drainage pipe 39.

Then, using the pinch toggle switch 36 and the knife control button 32 (not shown in FIG.) Of the clipper 22, pinch, clipping and chuck section 24 are performed in the manner described above.
