Description

In industry, pneumatic distributors of fibrous material coming from a single source are known, in a group of machines operating in parallel, including a product pipe connected to a maotine. supplying pneumatic distributor, equipped with divided shafts grids, mounted above the hoppers of hackle machines, and air duct with a switch valve.

The proposed pneumatic distributor of fiber material coming from one source, for example, from a scutching machine, but a group of Parallel-working, for example, carding machines, differs from the well-known one in that the production pipeline is equipped with a tee with a self-switching valve that separates the product conductor into several, for example, two branches fed alternately and the grids of each shaft divide it into two chambers, to one of which the product pipeline is connected, and to the other air duct. In the chamber with the connected air duct, an adjustable damper is mounted, activated by the photo sensor signal when the hopper of the powered machine is filled, and narrow linings are moved along the grid, and in the chamber with the connected pipeline, the check valves are activated by the self-switching valve signal.

The air pipeline switch-switch consists of a pin driven by a cam mechanism, passing through the branches of the air ducts, and dampers mounted at a right angle to each other, alternately blocking the air ducts.

These differences contribute to the increased uniformity of cotton threading machines in the production line of cotton production.

FIG. 1 shows a pneumatic dispenser of a fibrous material; in fig. 2 - valve-switch, section along AA

No. 149330-2 of FIG. one; in fig. 3-bunker of the fed machine with a shaft mounted above it with a pneumatic distributor.

Pneumatic distributor of fibrous material coming from the scutching machine 1 in a group of parallel-working carding machines; in 2, includes a product pipeline 3 connected to a machine that feeds a pneumatic distributor equipped with divided shafts 4 shafts 5 mounted above the bunker 6 of carding machines 2 and the air line 7 with valve switch 8, which connects the branches of 9 carding machines 2 to fan 10.

The valve-switch 8 of the air pipe 7 consists of a pin // driven by a cam mechanism (not shown) passing through the branches of the air pipes 7 and mounted at right angles to each other of the G2 flaps, which alternately block the air pipes 7.

The product pipe 3 is equipped with a tee 13 with a self-crossed valve 14, which divides the product pipeline into two, alternately fed branches 9 of combing machines 2 Grids 4 of each shaft 5, divide it into two chambers (not shown), one of which is connected to the product pipeline 5, and to another air duct 7.

In the chamber with the connected air duct 7, an adjustable damper 15 is mounted, which is activated by the signal from the photo sensor 16 when the hopper 6 of the powered machine 2 is filled, and narrow slips are moved along the grid 4 (not shown in the drawing).

In the chamber with the connected pipeline 3, check valves 17 are mounted, which are activated by the signal of the self-switching valve 14.

The supply of fibrous material, such as cotton, from burrs, to the carding machines 2, is accomplished by diluting the air created by the fan 10 in the product line 3 and its branches x 9 located above the chambers 5 and the hoppers 6 of the carding machines.

With the help of a cam switch S, driven by a cam mechanism, each of the branches 9 of the pipeline 3 is alternately connected to the fan 10, which means that (and with the help of a self-switching valve from air dilution) the fibrous material enters simultaneously into all chambers of one branch 9 of the pipeline then the other.

The cycle time of the switch valve 8 can be controlled by the speed of rotation of its cams. The cycle time of the switch valve is set to be short in order to ensure that the fibrous material is often supplied to the carding hoppers in small portions. The frequent alternation of the power of the branches of 9 carding machines maintains the level of fibrous material in the bunkers with slight differences, which is one of the conditions for obtaining a uniform ribbon.

When the carding hopper is filled with fiber mater; up to a predetermined level, the beam of photo sensor 16 overlaps and automatically actuates the pneumatic mechanism 18, which closes the valve 15, as a result of which the air through the grid 4 from the chambers stops and the fibrous material does not enter bzdet.

When one of the branches of the product line 3 is disconnected from the fan 10, the flaps of the check valves 17 under its own weight are lowered, and the fibrous material (cotton) lags behind the grid 4 and enters the carding bunker.

At the next branch of this branch to the fan W, the incoming (sucked) air will raise the flaps of the valves 17, which (in the raised state) will disconnect the bunker 6 of the fed machine from the chambers, the shafts 5.

For more reliable closing of the valves (sashes), they are driven by a pneumatic actuator 19.

When one branch 9 of the product pipeline is disconnected from the fan 10, the material (cotton) and its suction to the grids 4 of the chambers 5 of the bins 6 are fed to another branch 9 of the combing machines 2.

The same size of the portion of cotton sucked to the grids of the cameras of carding machines is achieved by the corresponding installation in the air duct of 7 flaps 15.

The uniform distribution of the material (cotton) across the width of the fed (carding) machine is achieved by different installation of 4 narrow slips moved along the grid, which divide the grid into several sections of cotton suction.

When filling the bins of all combing machines of one branch with fibrous material, the feeder organs of the machine feeding the fibrous material into the chambers stop; simultaneously, the shutters 15 are opened above all the chambers of mines 5 of this branch of the combing machines so that the rest of the fibrous material found in the product pipes is small portions of mi in all carding machines of this branch.

The disengagement of the feeder organs of the feeder machine and the simultaneous opening of the shutters 15 above all the chambers of the bins also occurs when the bunkers of all carding machines are filled with the fibrous material.

In the case of a large distance of the carding machines from the threading (scutching) machine, the installation of an intermediate fan 20 in the immediate vicinity of the feed machine is provided.

At the conclusion of the CNIHBI this invention has industrial utility. The described pneumatic distributor of fibrous material has passed the test in the laboratory of VNIIiltekmash and is installed at the Red Flag Plant.
