Description

The invention relates to textile machinery and is intended for the weaving of shuttleless weaving looms.

The purpose of the invention is to increase labor productivity by increasing the convenience of inserting the thread into the hopper by means of a flexible hook rod.

Figure 1 shows the accumulate, general view; figure 2 - section aa in Fig .; Fig. 3 shows the tension adjustment mechanism; figure 4 - ballooning.

The weft yarn accumulator contains a device for adjusting the tension of the thread being wound onto the drum, having a self-winding type guide eye 1, a weft thread brake, o; from the bottom of elastic pipes 2 and J fixed on the axes 4 and 5 with the ability to adjust the force squeezing the plates and located between preparatory 6 and 7 with cutouts for centering the thread when it is wound, the electric motor 8 with a hollow rotor 9, on which are attached two O y. 11, one of which serves as a carrier for the thread, and the second for balancing the rotating system of the drum 12 for accumulating the thread fixed by the ring with pins (not shown), the mechanism 13 for laying the thread on the drum, the device 14 for controlling the length the drum of the yarn, the balloon limiter 15 having the opening 16, as well as the slot 17 for inserting the yarn into the peephole 18.

The drive weft yarn works as follows.

The thread is unwound from the fixed reel, the peephole 1 passes, is braked by elastic plates 2 and 3 and, freely passing through the holes in guide 6 and 7, the hollow rotor 9 and the guide tube 10, is wound on the drum 12 as the torus rotates. The threads of the thread are laid out in one layer using the ukadka mechanism 13. Upon reaching a certain thread line on the reel 12, determined by the position of the device 14 for controlling the thread, the drive is turned off.

At the beginning of the winding of the thread from the reel 12, which is determined by the machine tool pattern, it occurs. the inclusion of storage in the work. Removed from the drum under the action of the plotter's usia (not shown), the thread passes through the peephole 18 of the balloon guard 15 and enters the working bodies of the weaving machine. When the weft yarn 25 breaks in front of the accumulator, it moves upward from bottom to top through peephole 1 without using a weaving hook, is superimposed on top of the directions and using a flexible rod with a -JQ hook at the end (not shown) passed through the hole 16 in the balloon 15 The curved channel formed by the tube 10 and the hollow rotor 9 is pulled out outside the cylinder limiter 15. The thread slides along the bevels of the guides 6 and 7 and is inserted between their brake plates 2 and 3 through their slots. It enters the working bodies of the loom. When the machine is turned on, the accumulator is turned on and a thread accumulates on the drum.

At the beginning of winding the thread from the drum 4 of the barrel according to arrow 5 (FIG. 2) due to its ballooning and tension, the thread slides along the slit 17 and spontaneously slides into the eye 18. Partial sliding of the thread along the slit 17 occurs

when filling the weft yarn into the working bodies of the machine due to its tension.

When using the proposed accumulator, there is no need to use a weaving hook to thread the thread into the eye of the thread tension regulator, into the hole of the thread length control device and into the eye of the balloon limiter, eliminating the need for opening the balloon limiter to wind the thread into the eye of the balloon limiter and then closing it. Thus, only one hand tool is used: a flexible rod with a hook at the end.

The use of the present invention makes it easier to wind the weft yarn into the hopper.
