Description

Weaving attachments for changing shuttles on the move, controlled by sliding feelers and equipped with a slider that takes the lower hook from the magazine, are already known. The disadvantage of such devices is that the work of opening the cheeks of the shuttle box in them is performed by the hook supplied by the picker.

The proposed device has the peculiarity that, in order to free the shuttle from the store of the shuttle from the store to open the shuttle box's cheeks, an eccentric associated with the shocker, connected to a shaped lever connected with a spring-loaded rod with the box's cheeks, was used to jointly lift the latter.

FIG. 1 is a diagram of the adaptation of the feeler to the adaptation; in fig. 2 is a general view of a part of a Schenger type weaving machine with a device in the approximate form of its execution.

The fixture encloses a feeler (Fig. 1), for example, of the type Midget entering the shuttle and descending onto the shaft. If there is a yarn on it, the feeler cannot turn under the action of the spring 2, since its notch rests on the rough surface of the yarn.

Once the splinter is free of yarn, it shchunlo touches the smooth surface of the spool and, under the action of the spring 2, rotates together with the levers 3 to 4 counterclockwise. Detail 4a of the axis of the lever 4, acting on the plug 5, stretch the spring 6 and turn the detail 7 clockwise so that the end of the rod 8 rises. When the batana moves to the edge of the fabric, the bar 8 will touch with its end by the lever 9 and turn it together with the roller 10 clockwise.

Due to this, the lever 11 deflects to the right and, having stretched the spring 12, deflects the bar 13 to the right. The last OT is not the right dog 14, which causes the bar 15 to fall (Fig. 2). When the rod falls 15 its protrusion

16 will stop against the stop 17 fixed on the arm of the batan. Lastly, by focusing 17, lug 16 and advance bar 15 to the edge of the fabric. In this case, the lower arm of the lever 18, 19 will turn against the action of the spring 37, and its left shoulder 19 will lower. Thus, the eccentric 20 will turn clockwise and pressing the roller 21 will turn the shaped lever 22 clockwise around the spindle 23. The rod 24 pulled down by the spring 38 will lift and through the connection 25 and the bars 26 will lift both cheeks 27 and 28 of the shuttle the boxes. At this moment, the baton will appear already at the runner 29. The latter, under the action of the upper end 30 of the shoulder 18, moves to the reed, seizes the lower hook from the store 34 and pushes it into the space formed by lifting the pads 27-28. The old shuttle will be pressed out of the shuttle box, and the new one will take its place. At the same time, the bevel 55 of the rod 15 will overlap on the roller 36 and will land the rod 15 on the dog 11.

The stops 16-17 are disconnected and the adaptation stops. The springs 12, 37, 38, 6, 2 will bring its parts to their original position.

Subject invention

An adaptation to weaving machines for changing shuttles on the move, controlled by a slide bar, uplifted and equipped with a fall, pick up the lower hook from the store, distinguished by the fact that, in order to free the shuttle from the store, it leaves the shuttle from the store for opening the shuttle box , for joint lifting of the latter, an eccentric, kinematically connected with a damper, is used, which interacts with a shaped lever connected by a spring-loaded rod with w, box boxes.
