SU6485A1 - Adaptation to an automatic weaving machine to support the spool - Google Patents

Description

In the existing designs of the automatic weaving machine (Northrop and others), the lever supporting the spool is fixed on a fixed axis; This has the disadvantage that the direction of the force pushing to the saddle on the path of the bobbin to the shuttle is continuously changing and at the end of the movement a significant lateral force is created, which tends to pull the pin out of the bounce saddle. In addition, the support lever is retracted to the side of the spool itself, which is already deprived of the force-supporting lever on the last part of the way before entering the shuttle.

The proposed fixture is intended to eliminate these disadvantages in that the force pressing the spool passes through the center of a circle described by the axis of the holder which supports the spool even when it is partially in the shuttle.

In FIG. 1 and 2 depict vertical sections of the proposed device in two, positions, and FIG. 3 is the same, front view.

The device consists of the following main parts: a lever (fork) 1 (Fig. 1), mounted on a common axis with lever A and axis 2 and fixedly fixed on it with a retaining bolt 3; Z-shaped lever 4, pivotally connected to the lever 1 via axis 10 and normalized (up to contact with pin 9) by spring 8, fixed at the other end in the flush of the lever 1, and the holder b, which is jointly connected the lever 4 by means of the axis 5 and pulled back to the normal position (up to the contact of the added stop & the lever 4) by the spring 7 fixed by the other end in the flush ear from the lever 4.

The action of the knockout, produced by lever A, is controlled by the mechanism of the probe and is performed under the influence of the reverse clockwise movement of the lever A, which is regulated, in turn, by rolling roller B on the curve of angle C.

As the bobbin e (Fig. 2) approaches the shuttle box, the lever 4 with its lower arm approaches the plane d of the batan until it touches it, after which it slides along it (to the right in the drawing), rotating along with it around axis 10, fascinated behind him in the same direction pivotally. EVERYTHING with it is holder 6, while freeing the spool and allowing lever A (at the moment of contact between the spools and /) to perform an action of knockout.

Thereafter, bounce lever A and all parts associated with it return to their former normal position, indicated in FIG. one.

By attaching the thrust plane d to a known bias, it is possible to achieve that at the last moment the lever will turn out from under the spool and give the latter a free admission to the canoe.

The subject of the patent.

Adaptation to an automatic weaving machine to support the spool, characterized by the use of lever 4, rotating on a fork 1 attached to lever A, which serves to push the spool e supported by spring 7 into the shuttle by means of holder b, which is hinged pivotally on lever 4, with the lever 4, slipping along the plane d of the outgoing batan, retracts the holder b from the spool e when it is pushed into the shuttle.
