Description

- In FIG. Figures 1, 2, and 3 show front, top, and side views of the proposed fixture for a cross loader, and FIG. 4 a and 46 according to the spring, the origin of the blow received in conventional cross-treading machines.

In known cross loader machines, a yarn guide (no matter whether a uniform skein is produced or an uneven skein) is driven by a grooved eccentric. The disadvantage of this design lies in the noisy progress of the machine, since the yarn guide, whenever it begins to reverse, ending the course, loudly hits it. If, however, at the same time, as is the case with unequal hanks, they work from thirty to fifty spindles and more, then the blows of individual floaters are Nrevrash, but the sound is loud. The origin of this impact is illustrated in FIG. 4 a and 4 &. The numeral 1 denotes an eccentric wheel with a groove 2. It moves the roller 3 by means of a pin 4 of the yarn guide 5, which is mixed on the guide shaft 6 back and forth. When the thread guide, and with it the roller 3, is completed, according to FIG. 4 ft., His turn, he, having still living strength, strikes the whole force with a roller into the opposite wall 7 of the groove 2, as he suddenly stops in movement in one direction and pushes back in the opposite direction. With one turn of the eccentric, therefore, two such hard blows occur, which, depending on the number of spindles, condense into a long unnerving noise. They tried to weaken the eccentric impact, but put it together with the thread guide into the drum silencers, but the improvement was insignificant. Since the number of revolutions of this machine cannot be greater than a definite one, this is a disadvantage in its operation. Roller 3 cannot be dispensed with, since otherwise pin 4 would soon flow around in certain places, and the direction of the thread would not be accurate. The roller itself wears out and applying it is tantamount to a significant weakening of the collar; This deficiency can only be compensated by hardening the pin and roller. But then, in the case of increasing the speed of the machine to the limit that the winding thread can withstand.

POSSIBILITY of breakdowns increases. From this it follows that the machine cannot be used as much as the strength of the thread would allow.

The proposed device aims to eliminate all these disadvantages. A known crank drive is used for this with a linkage rigidly connected with a yarn guide and driven by a crank. Since the reel rotates at a uniform speed, the yarn guide must, in order for the winding to be the same, move back and forth evenly. It is therefore necessary to arrange the device so that the same results are obtained as with the use of a special grooved eccentric curve. If the crank was set in motion by the main shaft by means of an ordinary gear transmission, the crank would rotate evenly, but the link and the thread guide would move unevenly. Therefore, a special transmission drive, namely a heart-shaped wheel drive, which causes the crank to move unevenly, is inserted between the main drive shaft and the crank. This irregularity is made well defined and is designed so that the movement of the link and the yarn guide becomes uniform.

According to the invention (FIGS. 1-3), the helical wheel a mounted on the drive shaft fe is in engagement with the screw wheel b fitted on the shaft I. The heart-shaped wheel c is also loaded on this shaft, which works in conjunction with another forest. d last fixed on a short shaft yes. A crank e is also mounted on this shaft, which drives the crank with the link, namely the trunnion of the crank e enters the notch s of the slider f connected to the y guide, in order to avoid the rubbing of the trunnion d to the notch s rotating roller 7i. The casing, in which the bearings for both shafts I and W are mounted, is also provided with directional grooves o for a slider f. On the spindle p placed reel g.

It is recommended to make the gear ratio of the screw wheels a and and as 1: 3 and both gears as 1; 2, so that with one revolution of the gear wheel d, the drive shaft It will make six turns. With this one turn, the yarn guide will go along the reel r forward and backward between the points gg. and v. The heart-shaped shape of the gear wheel c and the corresponding gear wheel shape give the crank an irregular “speed at which the cutout s and the thread guide g would move uniformly. Since there is no resistance in places where the stroke changes, and therefore there is no impact, the return motion of the yarn guide occurs without much noise. The lack of resistance is associated with the ability to start the machine as quickly as; this is allowed by the strength of the thread. Thus, it is meant to be able to drive the car faster than it has been until now.
