Description

The combat mechanism of the lower-loom weaving machine of the system. Platt has a number of flaws that are the limiting factors in the operation of the automated “Platte” machine tool.

The main disadvantages of the Platt combat mechanism are that the spring shock absorber (fungus) does not provide a clear and constant landing of the shuttle in the shuttle box.

When the shuttle enters the shuttle box, the spring of the shock absorber (fungus) is compressed by the strap, and the hook before the start of the next kidney is in the box under the force of the spring of the shock absorber, which tends to take it out of its normal position. The presence of such a position leads to frequent rebounding of the shuttle and its incorrect arrival in the opposite box.

In addition, the spring shock absorber does not possess the same braking elasticity of the shuttle, which is created by a belt shock absorber (bed-covered belt, Drescher-type loop, etc.);

This deficiency has a particularly sharp effect on the work of the Plattovsky camp (78).

With an automatic spool change where a shuttle is required to fit into the shuttle boxes.

The second most significant drawback of plattovsky bots is the non-fixed races at the end of the logon locks and the absence of a linear movement of the end of the drive. The free position of the race at the end of the drive leads to the fact that the races and the end of the shoulder of the tracks wear out quickly, as a result of which the force of the shuttle of the shuttle and the direction of the impact of the race at the toe of the shuttle change.

The movement of the upper end of the shoulder strap in an arc creates the possibility of bumping it by the bobbin disks of the drum.

The practice of working on automated machines has shown that the end of the shoulder straps is required to be trimmed, and in order for the races not to jump off the shoulder straps, safety peaks are made on the cheeks of the shuttle boxes, which worsen the working conditions of the spool changing mechanism.

In addition, the Plattov races are larger in size than the Northrop type race and more material and space is required for its manufacture in the shuttle box.

In order to eliminate these drawbacks in the combat mechanism of the system, Platt and to ensure the best performance of the automated machine, in the sense of a more correct flight and landing of the shuttle, the proposed invention was intended.

In the schematic drawing of FIG. I, 2 and 3 depict three projections of the proposed fixture.

The peculiarity of the proposed combat mechanism is that the Platt automated machine has a straight-line movement fixed on the walk, a race achieved by reducing the running motion with a conventional Northrop shoe with the Platt weaving machine combat mechanism. On Platt's iodbatannoy shaft A, a guide bracket 1 is installed, which is cast together with the uprights 2; A spindle 3 is inserted into the lugs of the uprights 2, on which the lever 4, which has a socket 5, freely rotates.

The wooden board 6 is inserted into the socket 5 and fastened with two bolts, as shown in the drawing.

A short shoulder strap 6 with a clamp 7 is connected to the strap 8, which carries at its end a rigidly fixed race of the type “Northrop.

The rest of the combat mechanism (combat disc with a roller, slide and roller) remains without changing the system "Platte."

The operation of the combat mechanism is carried out in the usual order, i.e. during the action of the combat roller on the slide, the roller, at its end 9, presses on the end of the lever 4, which, through a short drive 6 and collar 7, moves the drive 8 and produces a shuttle shuttle .

The return of the lead to the rear initial position is made under the action of the spring 10, which in this scheme should be somewhat stronger than the spring installed on the Northrop. The shock absorber in this model is a conventional batting belt, which is not shown in the drawing.

The subject matter of the invention.

A device for driving a crown with a linear movement of a race on a loom system. Platt, characterized by

that a shoulder strap 8 with a rigidly fortified gokk, mounted on a shoe of the usual type of Northrop machines, is connected by a collar 7 with a short shoulder 6 of the usual combat mechanism of machine tools of the Platte system.
