SU47647A1 - Adaptation to the weaving machine for slowing it down when the shuttle is undershot - Google Patents

Description

It is already known to use on weaving machines a device that protects the main threads from breaking during shuttling undershoots and consists of a lever that penetrates through a slot in the shuttle box cheek to control the shuttle in it, which is connected to the machine brake by means of intermediate links. In the present invention, in order to ensure reliable operation of such devices, regardless of the wear of the cheeks, shuttles, etc., as well as the possibility of easily correcting the disorder of the device itself that may be in operation, a spring-loaded lever is used that serves as a guide for the knife roller the batana and the help of intermediate levers interacting with the roller carrying the lever, the process of which penetrates to control the shuttle in the box through the slot in the batan gateway. In the drawing of FIG. 1 is a side view of the tool on one side of the loom; FIG. 2-side and general view of the device together

(96) (,

With Krivoschipnim-shaft and with a shuttle in a box; Fig, 3-device with. extreme front position of the battery and with a shuttle in the box; FIG. 4 - the moment when the device takes effect when the shuttle is not in the box; FIG. 5-device with crankshaft shaft in displaced positions; FIG. 6 is a front view of the fixture and batana; FIG. 7-top view of the device.

The designations introduced in the drawing have the following meanings: - shuttle, 2-way driver, 3-armor, 4- support, 5-lever, 6- roller of control device. The spring-loaded double-arm lever 7, which sits on the axis 9 and led to the end of the lever 5, is provided with a roll 8 (Fig. 2) entering the recess of the spring-loaded lever 13. The lever 13 supports the roller 14 of the knife 15, which is rotatably fixed on the batane. When lowering the lever 13, the knife 15 enters the notch of the lever 17, which is connected with the brake device of the machine 22, and brakes it. The connecting rod 24 carries the shaft 16 and the corner post 25. The stopper 19 at the end of the lever 17 seated on the shaft 18 serves to adjust the relative position of the notch of the lever 17 and the end of the knife 15.

The proposed device functions as follows. A double-shouldered lever 13 is attached to the frame 26 of the machine by means of the shaft 10. A spring 12 is attached to the end of the shorter arm, leading to the frame of the machine 26, which spring holds the lever 13 in the raised position; the other shoulder of this lever rests on the roller 8, which sits on the lever 7. On the double-arm lever 13, with its raised position, roller 14 slides 15 of the batana. The knife 15 sits on the shaft 16, which connects the blade of the baton to the crankshaft shaft 23 by means of the leash 24. The knife 15, carrying roller 14 at one end, has a wedge-shaped shape. As long as the double-arm lever 7 remains raised, the bat can work freely, roller 14 slides along the double-arm lever 13, and knife 15 remains raised.

The double-shouldered lever 17 is connected to the frame 26 of the weaving machine with a shaft 18. The end of the longer arm is provided with a stepped groove for the stop, a knife 15. The shorter end of the double-arm lever carries a stopper 19 that holds the lever 17 in proper positions. The longer arm is attached with rings 20 tons ha 21, leading to the braking device of the weaving machine. If the double-shouldered lever 13 is not in the specified EXCELLENTly elevated position, then the knife 15 can freely lower and come into contact with the edge of the recess of the lever 17 by means of its wedge-shaped end. The rod 22, in turn, acts on the brakes of the weaving machine, so that it stops.

If the shuttle is in the box, i.e., if the loom is working normally, the double-arm lever 13 remains in a position where the knife 15 does not interact with the lever 17. The double-arm equipped with a spring 11 lever 7 carries an eccentric rod that is not shown in the drawing the roller 8, on one side of which the lever 121 slides. If the hook is not in the box, then the small lever 5 interacts with the lever 7. Under the action of the roller 8, which is eccentrically sliding along the two shoulders, the lever should lower, so; in the same gnovenie knife 15 interacts with the stopping arm 17 (FIG.). FIG. 2 and 3 show that, if the shuttle is in the box, then the lever 7 remains stationary, the knife 15 cannot move, and the operation of the weaving machine proceeds normally. In the event that, as can be seen from FIG. 4 and 5, the shuttle is not included in the box, then the lever 7 is set in motion, as the device located on the bottom of the batan begins to function.

The lower part of the battery is provided with a roller 6 and calipers 4, 4 (Fig. 6 and 7). The levers 5 and 31 are attached to one of the ends of the roller 6. The lever 31 is provided, in turn, with a spike 32, shown in front in FIG. The plan in FIG. 7 and having a rounded protrusion at the upper part of the bat (Figs. 6 and 7), as well as a shoulder, carrying a roller 28 through the bolt 29, which slides along the edge of the part 27 attached at its ends to the frame 26 of the loom, as shown in FIG. 1. One of the ends of the spring 30 is attached to the roller 6, and the other end to the lever 31, so that the hook, if it is in the box, causes a certain pressure. In opposite | In the same case, the roller 6 begins to oscillate until the end of the appendix 32 is above the bat, as shown in FIG. 6. The pressure mentioned above takes place, the baton is in the position shown in FIG. 1. i.e. when the shuttle has finished its movement and is in the box. ; The roller 28 slides as shown in FIG. 1, part 27. If for some reason the hook does not enter the box and the bat is in the position shown in FIGS. 1 and 4, then under the action of the spring 30 an oscillating movement of the roller 6 occurs, causing pbi4ah 5 attached to this roller occupy the position shown in fig. 4 and 5. The lever 5 interacts with the roller 7 and causes it to perform an oscillating motion. Similarly, the roller 8 on the lever 7 eccentrically slides over the two shoulders of the lever 13 and causes it to also perform an oscillating movement, as a result of which the knife 15 is lowered until it touches the stop lever 17.

As a result, under the action of the gig 22, which controls the braking device of the weaving machine, the whole mechanism stops.

The subject matter of the invention.
