Description

The proposal aims at a machine design that would allow working on simple Plattovsky 4/4 machines without speed reduction, namely 220-230 beats per minute, and would give greater performance than current machines, which is achieved:

1) A change in the principle of putting the spool into the shuttle.

The spool is invested in the canoe not by the action of the baton on the bouncer, in which the initial speed of the bouncer is greater than the final speed, due to the arrival of the baton at the right moment for the knockout of the shiuli to the dead position of the crooked and, due to this, some delay in the return of the bouncer. The proposed automaton is driven from a stubborn shaft acting on the driver almost at a constant speed, and the return waste is produced at the moment when the bat comes to a dead position.

2) The shlull head is guided into the cells between the clips that prevent it from changing its position relative to the axis of the shuttle.

3) Avtomat a switch, - if the chelots are short, or its swelling is ““ ivayii ”; from the race, it is integral with the machine gun, which made it possible to make it highly sensitive to work and less disorganized.

4) To adjust the flight of the shuttle in the “bats of the batana, make a crouton, thanks to which you can properly stop the shuttle in the required place under the bouncer within the limits of tolerance”.

In FIG. 1 of this selection shows the front view of the mechanism itself and aitbmata in a collective form; FIG. 2- View of his eboku; FIG. his top; FIG. 4 shows a view of the automaton installed on the machine P Atta; fig.- his side a pack.

The proposed machine arrange the following way. The frame S4 EtaMK is screwed with two bolts, a bracket 32 (Fig. 4 and 5). On the bracket 32, the prong joints are assembled with three bolts together with the bycicle holder (detector). At the bottom of the cfakifa, no axis with a stubborn shaft is attached to two boats 1 of play 19, on its spindle 21 there is a p1 1 C 12, at one end of which a hook 13 of the striker is attached. The hook of the ball is always held in the lower half of the evening; as indicated (phi. 5) -. 12g with a spring b all latching is held in the lower position in the front, in, € Lach, installed with a bolt-buffer 23. This buffer, using the I / OF-1H1X under the Washer Head, places the Bfeiuie or lower the lever 12; this is a length of 8, so that the firing pin 20, at Zadopa Sh, has a gain of 17 mm. Koc- | fe 4 levers 12 th leg 14 is connected to the lever arm forks 6. The length of the string 14 is set such that the bouncer 10 does not reach the soldier 33 by 1 mm when knocking it out; at this time, the fork lever 6 should fit close to the boltabuffer 11; The spindle 22, screwed to the lever 12, places the lever 17, which with one arm via the rod 18 connects to the hook 13, and the other arm of the lever 17 connects through the rod 35 to the lever 36 of the fork roller 37. The fork roller 37 is in two brackets 38. The brackets 38 are screwed in the breast pad 39. At the other end of the fork roller 37, there is a lever near the fork machine itself, with an arm length of 78 mm (not shown on the drawing). The lever and fork machine tool are supplied by our existing Witeker design. When the trimmed fork detects the absence of a duck in the shuttle, the hammer moves the lever, mounted on the roller 37, in the usual way, with the fork, and rotates the roller 37c by the known lever 36 upwards. The 36 t of the goy 35 pulls the lever 17, the other lever of the lever 17 pulls the hook 13 close to the head of the lever 12, as shown by the dotted line, and this puts the hook 13 on the action of the striker 20. Striker 20, -3. the hook 13, raises the lever 12 approximately at the same angle as the lever 12 has in the lowered position; At this time, the other end of the lever 12 lowers the bolt 14 and thereby releases the bolt of the blade 30 and allows the piston 26 with the trigger lifter switch 29 turned to it under the action of the spring 27 to move closer to the bat, and the fork lever 6 moves the trigger 7 to the protrusion a bouncer 10, and if the shuttle in the shuttle box is in the proper position, trigger 7 captures picker 10 by protrusion a and brings the kicker to soldier 33; In this position, the bouncer puts the spool into the hook. The bouncer 10 is raised back by the spring. When the striker 20 releases the hook 13, the spring b of the lever 12 will put the lever 12 and the fork lever 6 into its original position, as indicated in the drawing, and the ha 14 will hook with its wedge-shaped elevation. bolt blade 30 and move the piston 26 to its original position. When the hook at the time of the change of the spool does not reach its proper position, the hook will move the piston 26 with the switch 29 turned to it, which raises the elevator of the trigger 8 together with the trigger 7, and the trigger 7 will pass above the elevation (the bouncer 10 and the spool will not fit.) At the end of the bat there is a movable sukovaty cracker with stuffed skin on the side of the baton. The striker 20 is kept in the position as indicated on the drawing (Fig. 5). By turning back, the dowel 20, approaching the hook 13, deflects toward g and thus does not violate the installed correctness of the parts for switching on the machine.The subject invention 1. An automatic machine for changing the spools on a loom consisting of a weaving machine a cam disc, which, for the purpose of changing spools, through a system of tg and levers, is connected with the fork mechanism of the machine and with the spool bouncer, characterized by the use of a spring-loaded hook 13 (Fig. 5), which, in order to perceive the impact of the striker 20, permuted on the cam disc 5, which is seated on the prostatic shaft, is connected with a fork roller 37 by means of a pull-rod system and levers 18, 17, 35 and 36, for the purpose of changing the spools are connected to the spring-loaded outliner 10 by means of the spring-loaded lever 12, ti 14, blade 30, piston 2v, spring-loaded switch 29, plug b and trigger 7, striking the protrusion of the bouncer 10 when changing the spool. 2. When using the device according to claim 1, use the protrusion "1 on the switch 29 and the elevator 8 of the trigger, in order to prevent the change of the spools in the case of improper installation of the shuttle in the box.
