SU15596A1 - Carousel loom with several shuttles simultaneously running - Google Patents

Description

The proposed carousel loom is intended mainly for producing seamless fabric, for example, for bags, mattresses, and so on. or to produce very wide cloths of cloth, such as, for example, for Eiranas in cinema, tarpaulins, etc., and have the goal of increasing the productivity of the machine, which is achieved by the simultaneous operation of several shuttles moving one after the other with continuous weft and unlimited length of the fabric produced, because as the individual spools of the base work, they can be replaced with new ones on the run of the machine, and the shuttle position allows you to lay a large weft spool. In the proposed machine, there are no heavy swinging parts, no impacts and losses, and all movements are smooth, circular, which allows to achieve a high speed of work, limited only by the strength of the base.

In FIG. 1 depicts a general view of the machine, the left part of the machine being shown in vertical section with the opening of the pharynx, and the right part is not allowed with the closed opening of the pharynx. For the sake of clarity of drawing, all repetitive parts

machine shown in one instance; FIG. 2, in side view, movable plates, pushing apart the warp threads to form the pharynx and to form slots for moving the shuttle, with a partial cut thereof; FIG. 3-horizontal sections of the machine, with the first quarter of the drawing depicting pr13res FIG. 1 by plane I, I, the second quarter is the same, plane II, II and third by quarter-plane III, III, where in the first quarter the moving plates pushing the warp threads of the base are shown for the clarity of the drawing in a limited number, the points on the inner ends of the plates indicate the position of the threads the basics; and FIG. 4- shuttle with spool in longitudinal section. The machine is located on 4 wooden beds A, A {FIG. 1, 3) fastened crosswise with crossbars on top and below the image of ledges 5i, on which ring frame C lies. Inside the frame is a toothed rim D with ring cover / C supported by balls on frame C. The rim together with the cover is driven by means of the conic wheel - M operating from the drive. The rim encloses the cylinder -iff, suspended from the crossbars J when the rod N is approached, so that there is an annular gap R. between the rim and the cylinder. Above the frame C, a ring comb B having radial slits is approved with the aid of racks O. The second one is the same comb, suspended with the help of m r Oi to the crossbars B. The number of cutters in both combs should be the same, in this size of the machine is about 720, and the cuts are located respectively in the same vertical planes. In these cuts, p and pi plates are inserted (Figs. 1 and 3) to move the warp threads. Each plate (Fig. 2) has in the front part two eyes E, e, through which the warp threads pass, and below there is a mushroom-shaped notch along which Christmas tree slides, and a process r or gi of different height. The base, wound on individual spools, is arranged in whole grabs over the machine around the circumference (shown in the drawing e); each base thread then passes through the teeth of the separating 5. then separated by rings G, PI, and, passing the ring FI, is alternately threaded into the eyes of the plates p, - pi. The ends of the warp threads are fixed on the surface of cylinder N. If you now move the plates p, Pi in opposite directions, t, -e. even to the right, and odd to the left, the throat is formed, in which a hook with a weft thread can pass (Figs. 1 and 2). The plates are moved apart by the following construction. On the ring K, a leash is strengthened, consisting of an inclined stand a on which the board b is fixed (Fig. 1); On the pole there are 4 guide plates d, d, di d (Fig. 3). These plates, capturing the processes g, ii, located on each plate p, Pi, move the latter in opposite directions. Suppose that the pharynx is open, then the plates p, PI should stand in such a position as shown in the drawings (in Fig. 1 on the left side and in Fig. 3, representing them in plan, in the upper part of the left quarter) and we will rotate the toothed rim KE, and with it the whole system, clockwise, the d, d guiding planes (Fig. 3), grasping one left and the right processes of the other, move them to the middle and at point d t one pd. |

At this point, the pharynx will be closed, as shown in the first figure on the right. The next moment, the di plane is lower, it captures only the longer processes of those plates that were on the right and moves them to the left, the dz plane enters it, is higher and captures the remaining short processes and drives them to the right. After the passage of the guide planes, the shed will open again to skip the shuttle, followed by a second system with plates d, d, etc. From this it follows that from the four guide planes the front pairs of their of, d must be the same height, and in the back pair, one protruding forward should be lower and only capture longer shoots. Moreover, if on the first system it was on the left, then on the second it should be right, and so on.

The shuttle represents a metal plate shown in figure 3 in plan, and in figure 2 in transverse and figure 4 in a longitudinal section: the front and rear sides of the plate v are beveled in convex and concave arcs, facilitating the movement of the shuttle under pressure of the moving plateJJ, j) i . A pin is attached to the shuttle's plate, carrying on itself a spool with weft yarn (Fig. 4), surrounded by an arc f, having two peepholes, Wi to skip the weft thread, and the thread. is passed through wire hook I. The shuttle moves in the grooves located on each plate p, at its end, when the plates are moved apart to form the pharynx, all their notches form like two grooves (Fig. 1 and 2), Bi of which moves the shuttle . The plates themselves are the driving force for the shuttle when the guide planes d of the driver begin to move them towards the middle. For this, the rear part of the shuttle is beveled so that each plate acts on it at an angle of 45 °; at the same time, a pair of forces are formed that drive the shuttle forward, like pushing it out. For a given size of the shuttle, these pairs will be about 15. Since they act simultaneously, there is little resistance to each of them.

Wefting is done with a cone Z, fitted with steel needles and a conical cuff at the base. The cone moves along with the annular pad -K on which it is fastened, so that lapel 1, it rolls around the circumference of the cylinder //, due to friction against the edge of the fabric formed in this place. Since the radius of the blade at the point of contact is equal to the radius of the ends of the needles, the latter describe the cycloid, and due to the inclination of the cone and the fact that the base is located around the circumference, the needles enter into the base only in a minor space, therefore there is no touching needles for warp threads; using needles, wefts are pressed against the edge of the fabric that forms. Cone Z is shown in FIG. 1 on the right side for clarity, in fact, it is always in the place where the pharynx closes, if it is woven with a spade, if it is open when it is opened, if it is woven with prostrate. The fabric is cleaned as follows. Cylinder and. has a recess L on its surface (Fig. 1). In the interval P between the cylinder H and the ring lining K. the roller g moves, having a rim entering the recess of cylinder i. The roller t moves with the ring K. and is always 1 in the place where the bottom pharynx is formed, i.e. in the place of the greatest tension of threads. Since the roller with its body presses the fabric to the cylinder, and the rim presses it into the recess of the cylinder, the amount of fabric needed for this should come from above. Following the passage of the roller, the disk m moves along the fabric at an angle to the plane of rotation of the entire system. This creates a friction of the disk on the fabric, directed downwards, as if scraping, which causes the fabric that is released after the passage of the roller is pulled downwards. Accumulated with the machine under the machine, the fabric is folded away in the side by folds or cut off as needed. In the case of a weft yarn break, a thin wire spring I (fig. 1, 4) is released, which was previously held under tension by the weft thread, for which the latter is carried out, as shown in fig. 4, through the eye “and the wire arc D, then it touches the hook of the wire spring I and exits through the eye Jnj. The free spring I with its end touches the copper cylinder d, what closes the current. An electromagnet incorporated into the circuit attracts measles, thus releasing the brake latch. The brake drops and stops the machine. The spring I is made rather long and flexible, which allows it, after the current is closed, with the machine still moving, to deflect the warp threads back and remain in contact with the cylinder g for some time. When a base thread breaks, a droplet in a ring-shaped trough falls, having a bottom, cut zigzag-shaped into two non-contiguous parts; this closes the current and stops the machine. The pendants are located on the warp threads above the ridge S and the trough under it. In the drawing, these parts are not shown in order not to darken the drawing.
