Description

The subject of the invention is an automatically operating machine for the manufacture of ammonite cartridges, in which the processes of making the paper shell and loading it with a powdered explosive are performed simultaneously and continuously.

A known automatic machine for patronizing an explosive substance, consisting of a horizontal screw apparatus with a hopper, a mechanism for feeding the paper tape at an angle to the tube and a device for spiral winding of the paper tape, forming the shell, continuously filling it with a product of cutting and cutting it into cartridges. mechanically acting skin. This machine also simultaneously and continuously manufactures a paper casing and loads it with an explosive, but the production process of such a machine ends by cutting the casing into cartridges without plugging them from the ends.

The difference of the described invention from the known one is that in the new machine the device for winding the paper tape is made in the form of a warrior with rubber rollers and a gear system, the operation of the cutting knife is based on the principle of electromagnet triggering from the photocell when crossing the illuminator beam, and as a last operation Maschine provides for blocking the cartridge with the ends.

FIG. 1 shows a schematic view of a device made in a duplex version (each spindle operates independently); in fig. 2-cross-section of the warrior; in fig. 3-longitudinal section of the warrior; in fig. 4 types of longitudinal section of the cartridge after the operations performed with it.

The electric motor / (Fig. 1) transmits the rotation to the spindle unit 2. The conveyor 3 set in motion delivers powdered explosive from the bunker to the pneumatic screw 4, which directs it into the screw-tube 5. At the same time, winding is carried out on the screw no. 118064-2 -

1-cutting paper tape coming from the roll 6 at a certain angle. Before starting the machine, the beginning of the belt is wrapped around the auger tube and placed in the warp 7.

The burner (Figs. 2 and 3) dried, allowing the continuous formation of the paper shell of the cartridge and filling it with the product to the required density. It consists of a support 8, on which a ball-bearing 9 is mounted, in the inner ring of which the body 10 of the warlock is embedded. Three rollers 11 are mounted in the casing at an angle of 120 °. At one end of each roller, cylindrical gears 12 and bevel gears 13 are mounted on ball bearings. Cylindrical gears are coupled to a fixed gear 14 attached to support 8 with help and bearing caps 15. On the middle protrusion of the roller) / a rubber roller 16 is mounted and a bevel gear 17 attached to it is attached to the gear 13. An auger tube 5 passes through the hole of the warp in its lid, the end of which protrudes from the warmer by 10-15 mm. The rubber rollers 16 are pressed against the screw-tube and, consequently, against the wound paper tape, and the wall of their pressing is adjusted by the lever 18 and the set screw 19.

When the paper ribbon is loaded into the warp and the vine is continuously wound and the endless envelope is wrapped.

During augering, the product compacted by the auger screw (Fig. 1) shrinks the paper casing from the auger tube, while the rubber rollers rotate, controlling the sheath, and, being in engagement with the bevel and helical gears of the wicker, transmit he has a look at what makes it winding on the tube of paper tape and forming the core of the sheath. When the product feed is stopped, the scroll stops rotating, with a reduced feed, it slows it down, and with an increased feed, it accelerates.

After winding and finishing, the casing is subjected to waxing, for which it enters the steam-heated channel 20, in which it is poured on top of the molten narafin supplied by the pump from the tank 21.

Then the core of the sheath enters the device for cutting pieces of cartridges of a certain length. The cut is made by the knife 22 acting from the electromagnet 23 at the moment when the end of the rod doesn’t cut a beam of light from the illuminator 24 to the photocell 25 connected to the electromagnet.

The resulting cartridge is transferred by means of mechanical stackers 26 to a chain conveyor 27 for feeding to the end closure mechanism (Figs. 1 and 4), which performs the alignment operation of the cartridges on the tool 28, shaking the loaded product to a depth of 8-10 mm from each end of the cartridge on the device 29, pressing in the ends of the cartridge chucks of dense cartridge, prewaxed paper on the device 30 and rolling the ends of the cartridge with paper cups by means of heated rollers on the device 31. Delco cartridges ends is effected centering them relative to the working mechanism through the nip 32 to the stationary base 33.

The stencil application for cartridges is performed on paper tape before winding it onto the auger tube and is performed by the roller 34 in the form of continuous printing.
