The machine for inserting and fixing the plugs in the sleeves of the coils shown in FIG. 1, 1, consists of three} with the same type of heads 5, 6, 7 (Fig. 2, 3, 4), fastened with bolts in a common frame. The headstock 5 carries a shaft 12 with locking rings 13, 13, a coil spring 15 and a gear 14, which can move along the shaft along a key; the gear 14 bends around the chain with a thrust load 16. In the headstock 6, 7 a shaft 17 is placed, having on its part a square cuts entering the nut 18 fixed in the headstock 6. The ball 17 receives a rotational movement from the pulley that sits freely on it 19, periodically coupled to the shaft via a conical friction clutch 20. In headstock 5, 6, shaft 21 is also placed, and:; sagging along almost its entire length 4 kpnaiki (Fig. 6), connected between, at the right end his friend with dru.e) m. The left end of the shaft 17 is worn: 22, held by retaining rings and provided with a cut-out for the passage through it of the shaft 21, on which the parts L, A j5, B, B, 1, which rotate with the shaft and move along it Part A sits on part A. I can only have a longitudinal movement with it; parts G, 1 sit at the ends of the shafts 12 and 17.

When the clutch 20 is coupled with the pulley 19, the shaft 17 rotates, moves to the left and returns back from the load 16 of the part 22, when the parts sitting on the shaft, Г ст в тс to its original position, shown in FIG. 2, 3. The ring 23 also, like the parts A, B, B, is mounted on the shaft 21 on the keys with notches (Figs. 7, 8), which include the ends of the screws. When the shaft 17 moves together with the part 22 to the left, the ring 23 is caught by the springs 24, 24 under the influence of the springs. In the embodiment shown in FIG. 2 and 3 (the shaft 17 moves to the right), the ring 23 is uncoupled from part 22 and held by the spring dog 25. To part 22, the shank 26 fits, covering the rod 27 connected to the plug 28, which serves to engage the coupling 20 with the pulley 19 when the movement 22 to the right. In part 22, oval holes are made on both sides, which include spikes 29, 29, which are pressed by springs into the grooves of shaft 21, which have the purpose, while moving part 22 to the right, rotate it by 45 °, and during reverse motion, part 22 is also 45 °.

Part A ( Fig. 9, 9) consists of two disks 30, 30 with shoulders 31 and bushings 32, 32, which are fastened with bolts 33, 33 also with disks of parts B, B- (figs 12, 12), Bushings 32, 32 are mounted on the shaft 21 on the keys that enter into the recesses 34 (Fig. 9) and also into the notches of the keys (Fig. 7, 8). Both sleeves are interconnected by a nut 35 with right and left threads, during which they rotate can get closer and ra d1 | igat, entrance into each other. 4 bolts 36 are screwed into the nut, the ends of which enter the notches of the keys (Fig. 7, 8), moreover, in order to turn the nut 35, it is necessary to turn these bolts up to the output of the ends of the keys On the sleeves 32, 32, loosely mounted disks 36i, Zb11 | (Fig. 9, 10, 11) of part A (Fig. 10, 11), held by washers 37, 38 (ig. 9).

With the discs 36, 36i, a lever grip 39, 39, 40, and 45 is associated (Figs. 10, 11),

serving to hold the coil while the plugs are screwed into it; the levers 39, 39 are seated on a common axis 42, and the levers 40 and 45 are mounted on the hub 41 mounted on this axis and are respectively affected by the springs 43 and 44. The rotation of the levers 39, 39 and 45 is limited by the bolt 46 abutting on the nut 35. On disks 36i, 36i there is a second lever grip 47, 47, 48 similar to the first for holding coils during lubrication with glue. The system of levers 50, 50, 51, 51 serves to grip the plugs. The pivots of the levers 50 and 51 are respectively the rods of the bolts 54 and 55. The levers 51, 51 are connected to the levers 48 by elastic bars 56, 56 (Fig. 11; Fig. 10 is not shown) and when the levers 48 are turned to the left, they are raised, and when they are turned to the right, they are lowered. The levers 50, 50 are pulled away all the time to the right by springs (Fig. 11) through, through the plates 58, 58, with notches 59, 59, through which rod 60 (Fig. 11, 2) of the control apparatus is passed. The movement of the upper end of the lever 50 to the right is limited by an abutment of the wall of the notch 59 into the rod 60, and the amount of this movement is regulated by a spring 57 fixed in various grooves 61 of the plate 58. Tubes with tires L, K (Fig. 11, 3; fig. 10 the tires are not shown) are fed through the guide plates n, b, c, which are seated on the axle 62 and interconnected by a pin 63 (Fig. 11). When the plate moves down, its protrusion rests on corner 65, and the right end rests on the protrusion of the plate 50 (the figure shows the position when the guide plates should be lowered with the right ends down to the plate in the lower protrusion of the lever 50).

Plates 66, 66 (Fig. 10, 11), pulled by a load 67 and used to hold the coils rolling on the tires E, are mounted on the upper of the two bolts that attach the tires E to the rack from the corners 60, 60. At the right end of the plates 66, 66, the strips 68 are suspended with the corners 69 and 65 attached, equipped with adjustable stops 70, 70,, 71 and 7i for retaining the plugs, k Between the disks 36,, 36 there is an emphasis for the plugs when putting them on

consists of a cross-shaped disk 79, attached to part A by bolts and carrying a crossmember 81, 82, bolted, each, with two bolts 83 so that the bolts themselves are fixed in the disks, and the crossbars may have a slight movement along their length.

 Four curved plates 84 are pivotally connected to the disk 79. Both the plates 84 and the disks are equipped with lever plates 6, which serve to grip and hold the wire 89. As the crossbars 81, 82 move along the axis, the ends of the rods 85 and the bent ends of the plates 86 are pressed and pressed or moving away from the plane of the plates 84. In the crossbars 81, 82 there are long

 bolts 87, designed near the disk 79, to hold the plates 84 when attaching the wire, the entrance to the corresponding cutouts of the plates as the crossbars move. When turning the disc, the ends of the bolts meet the cams 80, 80

 (Fig. 11) and move them down (from left to right).

The wires 89, 89 extending from the tubular guides 78 (Figs 11, 12) enter the open plug parts b in front of the grinder; 1, the cross-pieces look and then

the crossbars are cut with scissors 90, 91. Since the bolt 87 at the top left comes out of the gripping plates 84.84, they start to turn the disk 79 by pulling the wire away from the crossbars 81 and occupy the position shown in fig. 12 top right. The wire is thus positioned along the diameter of the cuts of the disc with the ends clamped. and when the plugs are brought in, it is pulled out of its clips. Changing the length of the cut piece of wire is achieved by changing the fixing of the crossbars and knives. The springs 93 press the plates 84 to the crossbars, opposing the rotation of the disk to the force of inertia that draws them away from the crossbars.

Parts B, B (Figs. 2, 3, 13 and 13) are disks with four circular openings at the periphery, each of which is equipped with a swivel ring 94 with notches 96 that carry tubular, provided with longitudinal ridges on the outside, with spindles 97 sec. half 98 coupling with four teeth 99 and with the head 100 for the seal in her tube.

Details T, / h (Fig. 14) - a device for additional, in addition to the pinings on the spindle 97, fastening the plugs when screwing in - consists of couplings 101, 101 freely attached to the ends of the shafts 12 and 17. With couplings having two cuts, The arms 104, 104 are connected with hinges to the sleeves 102, 103 with cutouts for the passage of the stops 105, 105, which, when the shafts 12 and 17 move to the left, enter the rings 96 into the notch 96, and the earrings 102 and 103 become in a position perpendicular to the shaft axis, retraction from the shafts right ends of the levers Č04, 104 and clamping at the same time these levers to the rings 94. Left ends of the levers (jagged) clamp with the head of the tube 97. The end of the shaft has counter teeth, which it captures the coupling 98 and the ring 94 and rotates with it the entire system of parts 94-105. When the ends of the levers approach the coil flanges, the stops 105 meet the wall of the part 79 disk 79 and move them to the right, while the axis of the hinges 106, 106 also moves to the right and the levers 104, 104 release the plug and then move away from it to the right. During the reverse course of the shaft 17, the protrusions of the upholstery meet the wall of the notch 96 and

gi 102, 103 and occupy the initial position again (inclined to the left); also, the levers 104, 1041, with an abutment 105, tensioning the spring cover 107, are pressed against the cuts of the coupling 101 and held in a certain position.

The device for cutting the wire after winding it onto the plugs consists of a spindle 97 of the rod 111 inserted into the cavity (Fig. 15) with a hook on one

end and spring 110 on the other. When the shaft ends 17 or 12 are pushed in by the spindle 97, the shaft is dropped by the wire placed along the gauge diameter, and when it is reversed, under the action of the spring 110, it hooks this part of the wire to cut it. the sharp edges of the spindle 97. Mutual position-. parts of the device for feeding coils and stoppers to the machine, as well as devices

%; for lubrication with glue is shown in FIG. 3 and 11. The sleeves are laid on the U-shaped guides fixed on the beams 112,112 (Figs. 10, 11) and rolled up by the projection AO of the plates 66, which hold them up until they are seized by the machine. Guides K, K for plugs (Fig. 3.11) and guides for sleeves are attached to a STYLE of two gons 60 attached to the beam 10. Guides K, K are put on by hook-like cuts on crossbar 113 and are tightened by rod 114 (Fig. 11), passed through the holes in the squares 60 and having ..; ..;,. i (left and right and left threads). By rotating the rod for the head 115, the guides can be pulled together or moved apart to the required distance from one another.

The mechanism M for lubricating the sleeves in coils and plugs with glue consists of spring plate levers 116 (Fig. 11), planted on an axis 117, pivoted, by means of a flexible rod 118 and spring lever 119, by acting on the button 123 of the movable shank 26. Ends levers 116, provided with counterweights 122, exit the glue container L (Fig. 11, 3) and contact with the respective brushes 120 or 120 (Fig. 2, 3) fixed to the rods 121, 121 and located opposite the coils, clamped by levers 47.48 (Fig. 11). The brushes are in contact with pivoting plugs 64 and inserted.

into the bore of the sleeve with longitudinal movement in the respective guide rods 121 and 121 of the brushes.

The control device consists of a rod 60 (Fig. 11, 2, 3) with a lever 128 attached to its right end (Fig. 11, 2) connected to a stopper 26 so that in the latter it can freely rotate and move in the longitudinal direction with yvostovik. Lever 129 is provided with a protrusion designed to abut it (in the absence of a plug 50, 51 in the stopper or in the coil clamp 47, 47, 48) of the cutout wall in the retracted 57 spring plate 58 and insert the end of the lever 128 into the notch on the rod 27 (FIG. 2), in order to disengage the clutch 20 with the pulley 19 and stop the machine.

The work of the machine is as follows. When moving from FIG. 2 and 3 of the position of the part 22 to the right of the spikes 130 (Fig. 2), the shaft 21 is rotated 45 along with the parts sitting on it, the shank 26, moving the rod 27 to the right, connects the coupling 20 to the pulley 19, and then begins to move to the left ; the shaft 21 at the time of the return of the part 22 to the position shown in FIG. 2, will turn another 45. During this rotation, the stop 131 (Fig. 9, 9), pressing the lower branch of the lever 47 (Fig. 11), turns it to the left, the tubes 49 retract the plate 66 downwards, pass the sleeve to grip it with the levers 47, 48 (finding here the sleeve is previously allocated to the grippers 31 and levers 39, 40). At the same time, the lever 68 is lowered, the plugs are passed to the guides a, b, c to the grippers of the levers 50, 51. The levers 39, 45 are moved downward at the beginning of the shaft rotation by the stops 132 (Figs 9, 9). At the beginning of the shaft movement, the assembled coil is retracted to the right by grippers 31, and the lever 40 rotates to the right to pass the coil and depresses the disks 36 (to the right) from the sleeve of the assembled coil. When separating the stops 131 from the lever 47, the latter rotates to the right and takes the seized guiding the E coil between the lever 48 and its upper branch. The lever 48 t gami 56 turns the levers 51 to clamp the plugs in the proper place. Inserting the stop 72 occurs at the last moment of the rotation of the shaft 21, turning the lever grippers 45 and 39.

During operation of the machine, after each rotation of shaft 21 by 90 °, all parts A- / approach each other, plugs clamped by levers 51 and 50 are put on spindles 97 fixed in front side slots of part I, B discs, at the same time wire is screwed on plugs , Hope: for the previous move of the machine on the spindle 97 and turned out to be now in the upper slots of the disks - /, B and also greasing the ends of the bush with glue (by moving the brushes into them). Screwing of the plugs can occur either successively first, right, then left, or simultaneously, depending on the amount of resistance to screwing in one or the other; goy cork.

Instead of the above-described construction for reversing the screw 17, a belt drive from the motor can be put; Coupling 20 must then engage with a pulley placed on the shaft 17 to the right of it. The described parts of the device of transferring gigs and others remain unchanged.
