Description

The present invention relates to the construction of an automatic machine for assembling needles with tongues on semi-axes extruded from the walls of the needle. In contrast to the known automata, which carry out only filling the finished tabs into the slot of the needle and corebing the hole for the axis on the needle walls, i.e. not fixing the tabs in the needle, but only preparing the needle for further assembly operations, the proposed machine produces needles with fully fixed tabs. Further operations are reduced only to the finishing of the end of the tab in relation to the elimination of waste tape after its sections with an automatic machine and B finishing the needle hook, but not at all affecting the operation of fastening the tab in the needle itself. The automatic feeding of the machine with the needles from the magazine and the tongue belt occurs automatically in two mutually perpendicular directions.

In FIG. 1 shows a needle view, partly in a longitudinal section, with the end of the tongue tape set in the needle slot; FIG. 2 is an enlarged longitudinal section of the needle along the axis of rotation of the tongue; FIG. 3- view of the needle head with a chopped tongue, the end of which is not processed,

as the needles come out of the machine; FIG. 4 - front view of the machine; FIG. 5 is a side view of it; FIG. b - view from above; FIG. 7 is a view of a part of the machine along the feed line of the tongue tape; FIG. 8 is a view of the same part of the machine from above; FIG. 9 is a front view of the needle bar and both cores; FIG. 10 is a view of the needle bar with the needle threaded and cores on top.

As can be seen from FIG. 1-3, the end / tongue tape with a hole is threaded into the slot of the 5-b needle rod 2, and the axle shafts 3-4 of the material of the needle walls are pressed into the holes of the tongue, as shown in FIG. 2. As a result, a needle with a tongue on two semiaxes is known per se. FIG. 3 shows a needle with a cut-off tongue tape, the end of which consists in part of a waste tape. Ready zychkov tape periodically fed in the direction of m p (Fig. 4, 6, 7 and 8) to the cores 22-23 (Fig. 9). The same cores in the direction AB (in Fig. 6) are periodically supplied with each needle from the magazine / b, slid over the tongue with its slit, after which the cores 22-23 extrude the semiaxes from the needle walls.

For the periodic feeding of a tongue belt wound on a drum not shown in the drawing, a carriage 27 is applied in the direction of the slide, reciprocatingly moving in this direction. The carriage 2J spring 9 is pressed to the roller of the lever 24, the other end of which is adjacent to the cam 8 of the drive shaft 7. The carriage is fixed to the carriage 2 / on the side with a guide tube 25 for passing the tape (Fig. 8), also supporting the grip 26 pressed to tongue tape spring 27. The end of the grip 26 during the course of the carriage 27 to the cores. 22-23 captures the tape behind the holes in the semi-axes and advances the tape to the cores. During the return stroke of the carriage 27 from the cores 22-23, the end of the grip 26 extends from the hole in the tongue tongue and the latter remains in place, as it is held by the grip 25, pressed by the spring 29 to the tape. The gripper 28 is placed at an appropriate distance from the gripper 26 and its axis 3J is fixedly fixed to the frame. To flatten the tongue tape before approaching it to the gripper 28, there is a flat spring 32 and a guide tube 30. Before approaching the cores 22-23, the zychkov tape passes through the slit of the plate 33 and between the punches 34 and the matrix 35 (Fig. 7), after which it passes into the needle holder, consisting of two pairs of sponges 36 fixedly attached to the frame (Fig. 9-10). Between the upper jaws 36 on the roller 37 there is a gripper 55 which presses the tape against the lower jaws at a pressure of the plate 39 from above onto the gripper 38. The plate 39 is fixed to the end of the lever 40 rotatable near axis 4 and carrying a ram 34. Lever 42 with a screw at the end for adjustment , driven from the eccentric 7 / main shaft 7, serves to move the spring-loaded lever 40, which causes the chipping of the tape by the punche 34 about the matrix 35 and pressing the severed tongue to the matrix 35 and the lower jaws 36 through the slotted wall of the needle using the gripper 38. Shop n the known device for the needles in the drawing is not fully illustrated, except

brood portion / b for needles. The needles fed from the magazine are positioned against the pushers 3-J4 of the carriage 15, periodically reciprocating along the frame in the guides, parallel to the carriage 27, from the eccentric 72 of the main shaft 7 using the lever 43. When the needle moves parallel to the T3-14 pushers the needle located along line AB in FIG. b and its slot is worn on the tab between the upper and lower paired jaws 36 (Fig. 9-10). But the needle penetrates into the slot of the plate 44 of the carriage 27, which holds the needle in a horizontal plane. Following the chipping of the filed into the jaws 36 and into the slotted needle of the tongue tongue by the punch 34 and the die 35, the chopped tongue is pressed against the needle slot and to the lower jaws 36 using the grip 38 and extruding the semi-axes from the material of the needle walls using cores 22-23 activated by levers 19-20 from the protrusions of the fist W of the main shaft. The extrusion of the semiaxes occurs at the intersection of the TP lines of the tongue feed and the AV feed line of needles from the store. When moving the plate 44 with the carriage 2 / the continuous movement of the pushers 13-14 leads to the ejection of the needle with the tongue fixed in it into the slot of the machine bed, after which the carriage 75 returns to its original position.

The subject matter of the invention.
