Description

It is well known that a network is formed by a pairwise connection by a simple knot of threads coming from the neighboring nodes of the previous row.

In the proposed machine, designed for use with the above-mentioned simple knot, there are two rows of load-bearing threads on the spools of shuttles, which move reciprocating vertically along the guide along with the frame connected with the slide. In the lower position of the frame, one of the two rows of shuttles is shifted together with the box relative to the frame by an amount the size of which is wide for arranging the threads in pairs before knotting.

In FIG. 1 shows a view of a simple knot in a tightened and not tightened state; FIG. Figures 2–4 clarify the network access process using the proposed tool; FIG. 5, 5 - the general view of the double shuttle and its top view; FIG. 5 is an ABCD section of FIG. five; FIG. b-schematic view of the loop-forming hook; FIG. 7 shows the arrangement of shuttles at the beginning of each nodalization cycle; FIG. 8 is a schematic side view of the machine; FIG. 9 is a sectional view of it; FIG. 10, a U-part mechanism for switching on and off the combing ridge between the threads.

The network is made up of longitudinal threads, tied up in pairs in knots and going in a network in a zigzag fashion (Fig. 2). Each pair of threads goes from a double shuttle to the last row of knots.

The double hook (figs. 5, 5, 5 °) is a flat box, which is easy to stream into the loop, consisting of two cud halves, carrying k {and along one spool b with wound threads. Parts of the shuttle with and rf sit on shuttle washers 34, holding the shuttles in the proper position, but allowing the loop to pass under the shuttle. Thanks to such a device, the rows of parts of shuttles can be moved relative to each other by one step at the beginning of each nodalization cycle, which is schematically shown in plan in FIG. 7 (top-position before moving, bottom-after moving).

After tightening the previous row of nodes by supplying the network at the edge of the beam 4 (FIG. 4, position IV) formed by the previous cycles, the above-mentioned movement of the shuttle parts and the thread occurs. The combing comb / (FIG. 4, position 1), the entrance to the thread zone, combing them from the shuttles to the beam, thereby connecting the threads in pairs, the cdc is shown in FIG. 3. Posde etgr

each pair of threads is caught by the loop-forming hook 2 (Fig. 4, position I), which, turning around its axis by 270 °, forms a loop on itself, after which the combing ridge emerges from the threads.

The loop-forming hook 2 (Fig. 6) is provided on its rear part with a recess K intended to facilitate hooking of the loop in order to form the throat for the passage of the double shuttle with needles 3 of the upper hook 46.

Position III (Fig. 4) shows the moment when the needle 3 forged a loop. Next, the loop-forming hook 2 stretches the loop, and the double hook 5 at the same time moves towards the loop to its extreme position, in which the loop is dropped by the turn of the loop-forming hook onto the hook nose (position IV). Then the hook passes through the loop and pulls it into the knot on the prying needle 3 (position V), after which the prying needle comes out of the knot and the knot is finally tightened by feeding the net at the edge of the beam 4. The combing comb / returns to its original position and cycle is happening again.

The above networked process is carried out using the proposed machine, shown schematically in FIG. 8 (side view) and FIG. 9 (section), with FIG. 8 shows the position corresponding to the initial one, and FIG. 4 corresponding to the time the loop is thrown onto the nose of the double shuttle.

The machine consists of two beds with drive mechanisms, in the interval between which occurs the work of the working bodies of the network. All the necessary movements of the working bodies are obtained from the upper 7 and lower 8 shafts, which are kinematically connected between themselves by a pair of gear wheels 9 and W. a roller to the eccentric / 2 fixed on the gear wheel of the lower shaft gives the ridge vertical displacements, and a ton of 13, adjacent the roller to the eccentric / / reinforced on

gear top shaft, horizontal movement. The rotation of the loop-forming hooks is carried out by the toothed rack 15 located in the cavity of the ridge 2. The forward movements at the right moment of this rail are communicated by the lever 76 pivotally fixed on the string 5/5 at point 77, so that it can swing in the plane perpendicular to the drawing. Swing gets its end bearing the roller 7, rolling along the rim 19, having a bulge in the plane of the drawing. On the other side of the machine at the same lever comb gets a longitudinal movement. The movements of the shuttle frame 20 up and down along the guides 24 in front of the frame are carried out by means of the backstage 27 (Fig. 8) with a stone 22. Part 23 (box) of the frame 2Q (Fig. 9) can periodically move in the longitudinal direction, changing the relative position of the parts shuttles 5 according to the scheme in FIG. 7. This is achieved by the device on the moving box 23 side tongues 25, which in the lowest position of the frame goes into the gaps between the fingers 26 fixed on the water shaft 27. The drive shaft receives movement from the lever 28 hinged on the axis 29 to the rear machine frame. The lever 28 has a roller 30, interacting with an end cam 31 of the gear 32. For one revolution of the shaft 33, the gear 32 makes only half a turn; therefore, the fist 31 is able to move the lever 28, and through it the movable part 23 of the frame 20 in one cycle in one direction, in the next, in the other. The rotation of the shuttle washers 34 during the passage under the double hook of the loop is achieved, as in the existing machines, by running when the frame moves down the forked arms 35 of the washer shaft 36 to the fixed fixed pins 67. The pins, acting on the fork 55, turn the roller 55 to the desired angle. When reversing from the bottom up, the washers thus return to their former position. The combing comb 7 is led out of the thread zone by turning it inwardly around the roller 57, which is fixed on the carriage 38, sliding along the same guides 24 as the shuttle frame. The upward movement of the carriage, and with it the combing ridge, is obtained from the action of a cam 39, mounted on the gears of the lower shaft, a double-arm lever 40. The latter, turning around the axis 4}, pulls 42 the carriage to the upper position. In the lower position, the carriage returns the shuttle frame by hooking the dog 43 to it. When the carriage moves upward again, the dog 43 is disengaged by acting on its tail of the finger 44 fastened on the gear wheel of the lower shaft.

The comb ridge 7 is interposed between the threads by the action of a finger 67 (Fig. 10) on the process 62 of the toothed sector 63, which is in engagement with sector 64 of a roller 37, which rotates the ridge 7. The ridge is turned off by the same mechanism from two sectors 63, 64 ( Fig. 10) by acting on the appendix 65 of one of them with a finger 66, mounted on a rod 45 (Fig. 8), which is also designed for turning the upper ridge 46 with prying needles. T ha 45, moving progressively, parallel to its axis, and driven by an eccentric, similarly to the above, from the lower shaft, tilts the combing ridge with a finger, and then, when its upper head rests on the finger 47 of the lever 48 of the comb shaft 49 with the supporting needles, turns the latter to hook the needles of the formed loops on the hooks 2. The number 4 denotes a bar at which knots are drawn.

The supply of the finished network is produced by the felt shafts 50, the device of which is similar to the existing one. The shafts are driven by a ratchet mechanism from a finger 57 seated in a radial slot on the upper shaft wheel. To adjust the size, whose finger can be radially adjusted. The ratchet wheel 52 has an overlapping sector 53, which also results in an adjustment.

The drive of the whole machine is from shaft 33 through a pair of elliptical gears 57-55, slowing down the movement of the machine at the right moments.

A shaft 33 provided with a release sleeve may be rotatable.

either from an individual motor through a reducer, or a belt from a counter drive.
