Description

The use for the weaving machine of the bouncer, moving together with the batan during the folding of the spool, is already known. In the proposed device to an automatic weaving machine for changing spools, a spring-loaded bouncer is hingedly mounted on a lever with a process in the middle part. The latter rests on the latch of the bat when moving it, together with the lever, to the chest, until the stop of the process of the bouncer into the protrusion of the bracket, which serves to carry out the initial turning of the bouncer.

In FIG. 1 and 2 depict a general view (with a partial section) in two projections; FIG. 3 and 4-part device.

The bobbin disk 1 (Fig. 2), seated on the spindle 2, is provided with a long sleeve on which the disk 3 with keys and the disk 4 screwed to it with a plug 5 for the ends of the threads is mounted. In the eye of the movable lever 6 (Fig. 1 and 2), the bouncer 7 is pivotally fixed with a process in the middle part and a pull-down spring 8. The bouncer carries on the feeding dog 9 and the dog 10. The process of the bouncer 7

(42)

The grip 11 is connected to the two shoulders lever 12, pivoting from a finger 13, mounted on a disk, seated on a crankshaft. A vertical roller 14 (Fig. 3) with a curved tab 15, passed through the bar 16, its lower end is connected to the lever 17, the long arm of which is inserted into the slot of the latch 18, and the short arm is carried by a spring-loaded tip 19, retractable by the enable lever 20. Spring 21, pulling the tip 19, when moving it from the inclusion lever 20, goes beyond the axis of the vertical roller 14 and thereby sets the system in one direction or the other. On the beam of the batana 16, the bar 22 is screwed up with a straight-through hole for the passage of the process of the movable lever 6.

The device for changing spools is turned on either from the weft fork or the cob of the cob by turning the switch-on roller, and with it the lever 2b in the direction of the arrow (Fig. 1). When the batana moves to the chest (on the surf), tip 19 (Fig. 3, 4) will meet with lever 20 and, having leaned, will turn the corner lever 17, and

with him and vertical th 14. At the same time. 15 go; The opening hole of the shuttle and the dlinnbe. the lever arm 17 will turn on the axle to the shcheckle 18, which will close the hole in the bar 22. If the hook has not reached, then the foot 15 will be pressed into the wall of the shuttle, and the spring 21 will not reach the axis of the vertical roller 14 (Fig. 4) and put the lever 17 into non-working position. When the opening of the bar 22 is closed with the latch 18, the baton, moving to the breast, will meet with the protruding tip of the movable lever 6 and until the moment it arrives, will begin to divert it to the side of the breast.

The bouncer 7, resting its protrusion in the protrusion in the bracket (Fig. 1), turns, squeezing out the reel from the magazine and at the same time the finger and at the end of the bouncer will sink for the protuberance of the protrusion b and thus turn the entire drum. When moving to the surf, the speed of movement of the vyschibel is equal to the speed of movement of the batane. The scion of the bouncer 7 at the point of connection with the thrust 11 deflects towards the thrust rod, and the lever 12, having turned on the axis, will meet with the moving finger 13. This meeting moment corresponds to the moment of the meeting of the spuds: under the action of the finger 13 indenting the spike into the canoe, with an increased speed of movement of the bouncer. In the process of changing the spools the baton, going to the surf, leads the lever 6 and, having reached the surf, goes to the rear position, and after it the lever 6 under the action of the lever 12 through 11 on the bounce stick 7. The finger 13, turning the lever 12, finishes the work of changing the spools and the entire system under the action of the spring 8 will come to the non-working position until the next change of the spools. The bouncer, returning back, slides a finger and slides into the notch b. The feeder dog 9 fits the storage tooth - y -

the bobbin of the bobbin disk and turns it until the contacting dog 10 is in contact with the tooth of the other ratchet, pointing in the other direction, due to which the drum is locked from accidental turning. In order to manually rotate the drum when charging the spools, the tails of the thrust pawl and the feed, under the action of the fingers, are disengaged from the ratchet and the drum is rotated freely.

The subject matter of the invention.

Claims (3)

1. A device for an automatic weaving machine for changing spools, equipped with a spreader, moving together with a batan during the insertion of a spindle, characterized in that the spring-loaded bouncer 7 (Fig. 1-2) is hingedly mounted on the lever 6 with a process in the middle part, abutting The latch 18 (fig. 3) of the chestnut when moving the latter together with the lever 6 to the chest until the extension of the outgrowth of the vyschibel into the protrusion in the bracket serves for the initial turning of the vychibel and the installation of the lever 12 on the way of the finger 13. 2. The form of the device according to claim 1, characterized in that for turning on the baton the latch 18 serves as a corner arm 17 articulated with a long shoulder with the latch, fastened on the bat and carrying a spring-loaded tip 19 on its short arm (Fig. 4). 3. When using the device according to claim 1, applying a protector consisting of a bat passed through a bar and integral with the lever 17 of the roller 14 with a curved tab 15, designed when it stops in the nose of the shuttle does not fly to prevent the turning of the lever 17 to the ends of the lever 20. fig f p, -r: - -l  Cii;:,.
