The proposed machine has a fixed frame 1 and a part 2 rotating in the center of this frame, which serves to move the lamp feet holders from one position to another. Each of these holders (Figs. 11-13) consists of a pin 80 to which a fixed cheek 81 is attached, which together with the movable cheek 82 is intended to grip and hold with the help of a spring 83 the leg k of the lamp. Attached to the fixed cheek 81 is a bent, as shown in FIG. 11, a plate 86 serving as a support for supporting and connecting the wires of the lamp foot.

Mechanism A (Figs. 1-3) is driven by a sprocket 9 mounted on a shaft 11 supported on a cam plate in frame 1. In addition to the sprocket 9, there is also a sprocket 10 on this shaft to transmit movement to other mechanisms and fists 12, 13 and 17. The cam 12 rests on the roller 14, which is capable of rotating around the spindle 15 secured in the rail 16. The rail 16 can slide through the sleeves 21 along fixedly mounted in the tubes with liners 30 Shtangam 19 and 20. As a result of this sliding movement the rotation of the shaft 11, the slide 16 will periodically move in ol rods 19 and -20. In order to return them, a spring 36 is attached to the slide, which continuously presses the roller 14 to the knuckle 12. On the slide 16, in addition, two more fixed pins 22 and 23 are attached, around which the levers 24 and 25 equipped with the rollers 27 and 28 can rotate pressed by the spring 26 to the knuckles 13 and, respectively, 17. At the ends of these levers, the toothed parts 40 are fixed, between the teeth of which, when these parts come into contact with each other, may include supporting and supply wires that are fixed in the lamp foot. The levers 24 and 25 carry on themselves the pins 34, 35, which, in the extreme clamped position of the levers, rest against the fist 31 mounted on the shaft 15. The method of operation of the mechanism is as follows. At that moment, when the lamp leg i2; put into position with respect to the mechanism, the levers 24 and 25 are in the most diluted position. Due to the rotation of the shaft 11, the slide 16 will begin to move forward and the fists 13 and 17 will come in such a position that parts 40 of the levers 24 and 25 will be able to close the supporting and feeding wires of the legs / s between their teeth. In order to make possible the return movement of the slide 16, for the shaft 11, a slot 37 is made in the latter. The moment when the support and supply wires are finally clamped by the lever parts 40, the position of the mechanism shown in FIG. 2. Upon further rotation of the shaft 11, the roller 14 together with the slide 16 under the pressure of the cam 12 will begin to move away from the lamp foot Jc. As a result of this movement, the rollers 27 and 28 will begin to run away from the cams 13 and 17, and the levers 24 and 25 will be compressed by the action of the spring 26. To prevent them from being compressed too much and the wires could not be damaged, the pins 34 and 35 abut against the stop 31 at the right time and thus prevent further movement of these levers. Since the carrier 16 still continues to move in the same direction, the wires closed between the parts 40 of the arms 25, 24 are drawn between the teeth and straightened. When the slide moves backward, the levers 24, 25 again diverge, and the lamp foot moves to the next position. The fixture used to bend the wires is driven by the sprocket 50, which is rotated by the chain 7 (Fig. 1). This wheel is mounted on the shaft 31 (Fig. 4 and 5), which has a support in the frame 1, equipped with a fist 52, which slides over the roller 53 fixed on the slide 55, which informs the latter forward movement on the rods 57 fixed on the brackets 60. Slide 55 bear the cheeks 67 and 68 and the bracket 62, on which the levers 63 and 64 with the cheeks 65 and 66 are fixed on the wasps x 80, 81. All this together forms, as it were, double tongs 65, 67 and 66, 68. The stops 72 and 73 are rigidly connected to the bracket 60. When the levers 63 and 64 touch these stops, the latter force them to turn on axles 80, 81, whereby the wire The pins are clamped with double pincers 65, 67 and 66, 68. After this, the carriage 55 moves backward, and then the levers 63 and 64 move away from the stops 72 and 73 and then are pressed by the action of the springs 69 and 70 to the stops 74 and 75, which limits their reverse movement. Wires with acquire a curved shape shown in FIG. 5. At the moment when the slide reaches the k position furthest from the lamp foot, the latter moves further and is installed against mechanism C. Mechanism C (Fig. 1) is set in motion like mechanisms L and -In chain 7 of sprocket 100 mounted on a shaft 101 provided with a cam 102. The roller 103, capable of being rotated on a spindle fixed in the slide 105, is pressed by the spring 108 to the cam 102 so that it all slides over the latter. The slides 105 can be moved with clutches 106 by -TU to the rods 107, which are fixedly mounted on the arm 117. The slides 105 are also provided with a pin 110 on which the pliers 113, 114 can rotate. These pliers at one end are provided with cheeks 130, 131 knives 115 are fastened to them by means of bolts 116, and rollers 118 and 119 are controlled by another, controlled by a fist 121 mounted on shaft 122. This shaft 122, which is seated in bearings 123 and 124, is connected to lever 125, which is shown in the drawing only partially. The lever 125 in one way or another can be brought into periodic motion. In this case, the cam 121 will push apart the rollers 118 and 119, overcoming the action of the spring 124. The cheeks 130 and 131 will shrink and the knives 115 will cut the wires. Depending on the desired length of the latter, the knives are fastened with bolts 116 in a certain position.

The following mechanism, D (Fig. 1), to which the leg is supplied, is similar to the described mechanisms A, B and C and differs only in the design of its sled 156, which are driven in exactly the same way as the sled 16, 55 and 105 of the previous mechanisms. They consist, as shown in FIG. 10, of the main body, in which an opening 176 is made for the shaft 177, having an eccentric 178. A rod 177 is mounted on the latter, to which a punch 181 is attached by means of the bolt 180. Against this punch 181, a fixed punch 182 is located, fixed by means of the bolt 183 Shaft 177 is rotated by a sprocket 175, which is driven in rotational motion in a manner not shown in the drawing. The eccentric 178 lowers the punch 181 whenever the sled is in such a position that the wires are between the punches and the latter flatten the ends of these wires. After a flattening movement of the sled 156, the fist 152 retracts and

the foot can move again to the next position E.

Mechanism E (Figs. 1, 14 and 15) is driven by a sprocket 200 mounted on a shaft 201, having a support in the frame. A gear wheel 231 and cams 202 and 215 are also mounted on this shaft. The roller 203, which can rotate on the spindle 204, follows the movements of the cam 202 overcoming the action of the spring 235. The slide 205 can move along rods 207 similar to the rods of previous mechanisms. On the slide 205, a stop 210 and a lever 211 are attached to this slide by means of a pin 242 on which it can rotate. The lever has a tongue end and is driven by a lever 213, which is controlled by means of a roller 214 by a cam 215, overcoming the action of the spring 243. The lever 220, mounted on a pin 221, is equipped with a roller 223, controlled by a cam 224. This cam 224 is attached to the shaft 225 , rotating in bearings 226 and 229 and equipped with a gear wheel 230, which is in engagement with the gear wheel 231. With the lever 220 by means of a pin 219, a lever 212, rotatable impaled on this pin. The lever 212 is provided with a forward-pointing fist 218, which is pressed by the spring 222 to the forward protruding surface 216 of the stop 210. When the lamp foot 1c is brought up by the rotating part 2 of the machine, the slide 205 moves forward and the flattened ends of the wires with the tongue end of the lever 211 are pressed forward the stop 210. At this point, the cam 224 is rotated at such an angle that the roller 223 is in the position closest to the axis of the shaft 225, and the lever 212 is in the most extended position. The spring 222, with the slip plane 217, presses it against the protruding surface 216 of the stop 210. In this position of the protrusion, the forward fist 218 will be opposed to the wires with the lamp foot / g. Upon further rotation of the cam 224, the lever 212 will begin to approach the leg A and the slip plane 217, following the profile of the forward protruding surface 126, will direct the movement of the cam 218 so that the flattened end of the feeding wire will bend around the zyko-like part 211. When this is achieved, first, the lever 212 moves back, then the tongue of the lever 211 comes out of the hooked end of the wire c, and then the slide 205 returns to the position furthest from the lamp foot, so that leg k gets the opportunity movable in the next position F.

Fixture F (Figs. 1 and 16) consists of a turret support 249, which is rotatable around shaft 250, and is driven into a periodically ceasing rotational movement by means of a system of gears 252, 253, 254, where these movements correspond. the movement of the moving part of the mask 2 | FIG. one). The turret 249 is provided with holders 255 for the individual nets 256 to be attached. These holders consist of a fixed part 248 and a movable clip -258 between which the net is held. As can be seen from FIG. 17, the mesh 256 has a retaining wire 257, the ends of which must be welded to the wires b. The mesh is inserted into the holder in such a way that the ends of the retaining wire 257 come exactly at the desired position relative to the wires b at the moment of attachment.

The connection is made using a welding / welding device, which consists of welding pins 263 and 264, which are attached elastically to the brackets 265 and 266. The pins move in the guides 269 and 270 and can be attached to the levers 267 and 268, driven by the fist 271 (Fig. 1). This fist is mounted on the shaft 272, which is rotated by means of 1 sprocket 273 and chain 7. The third crank arm 260 (Fig. 16) can rotate around its axis 261 fixed in the frame 1 and driven in a manner not shown in the drawing . As it moves, it hits a roller 259 attached to the clip 258 when it is in the working position. This movement, which occurs after the wire is welded to the wire, is removed by the clip 258 of the holder.

the grid and release the latter, while the holder with the foot moves further to mechanism G.

Fixture G (Figs. 1, I 8, 19 k 20) is provided with a turret support 307 with holders 308 having parts 309,312 and 313 serving to clamp and bend the flat anode plate into the cylinder. This plate is bent at both its ends at a right angle in order to attach these bent edges to the wires and the lamp foot. For this purpose, parts 312 and 313 are equipped with studs with rectangles with micro-cavities 310 and 311, and the flat anode plate can be rolled up, just between these two teeth and part 309. The mandrel 314, fixed on the arm 325, is connected by a hinge with a lever 320, which sits on axis 327, attached, in turn, also to bracket 325.

The pillar 301, located fc rotatably around the shaft 303, is rotated from the sprocket 300 and chain 7 (Fig. 1). On the column 301 (Fig. 18), the fists 302 and 3U2 are reinforced by which the lever 320 and the crank lever 322 are controlled using the rollers d and e on them. The crank lever sits on the axis 326 strengthened on the same bracket 325, and is under the action of the spring 323, with its end 318 adjacent to the plate 328, in which the pins 330 and 331 are fixedly attached. These pins are directly connected to the parts 312 and 313; a pin 330 rests on a spring 329, which at the other end presses against a portion 309.

If the end of the cranked lever end 318 moves to the left (Fig. 18), then the pin 331, having overcome the action of the spring and 319, will also move to the left. At the same time, the spring 329 will be compressed with the coupling 330 and, as a result, the holder part 309 will be pressed against the anode plate (FIG. 19). This movement continues until the plate anode rests on mandrel 314, after which the plate is folded around mandrel 314 (Fig. 20). The movement of part 309 will stop, while parts 312 and 313 will continue on their way. Final burn

The plate abutment around the mandrel 314 is produced by the cheeks 350 and 351 of the movable tongs 344, 345 (Fig. 21 and 22). These pincers have a fixed axle 341, fixed to the sled 340, which can move along the rods 342, mounted on the bed 1. At the ends of the pincers opposite to the cheeks 350 and 351, rollers 346 and 347 are sitting and the ends of these cords are spring 338, which presses the rollers 346 and 347 to the fixed stop 348 on the stand 349. The crank lever 355 on the axis 456 is attached to the bracket 325 and has rollers 358 and 358 at its ends. The first one slides along the fist 302 controlling this lever, and the second rests on, the sled 340 and serves to communicate its forward movement when turning those leverage 355.

When the plate anode is bent as shown in FIG. 20, the slide 340 moves further to the left and portions of the holders 312 and 313 move away from the plate. In this case, the stop 348 enters between the rollers 346 and 347 AND; 5 moves them so that the cheeks 350 and 351 seize the mandrel 314 and compress the plate (Fig. 21), which assumes a cylindrical shape and between the curved ends of the wire and the lamp foot.

Mechanism G is equipped with pins for welding 371 and 372, which are movable under the action of levers 380 and 381 in brackets 373 and 374 connected to each other by lever 377. Lever 381 is driven by rod 385 (Fig. 1) and communicates its movement to lever 380 by means of articulated at the point 384 of the levers 382 and 383. The lever 377 sits on the axis 378, which is fixed on the bracket 379 and can be moved up and down by the vertical bar 393. As a result of this up and down movement, the welding device is brought into position and out of it. When the welding device comes to a working position, it is driven by a crank arm 385 rotating around a point 387, which is controlled by a cam 388 and a roller sliding on it. This fist sits on the same axis with the sprocket 389 driven by the chain 7. The gear system 390, 391 and 306 is used for driving the turret.

The interaction of all the described parts of the mechanism of O occurs in the following way. When the lamp foot is moved to its working position, the mandrel 314 of the floor with the lever 320 moves upward, the screen net already attached to the foot. Thereafter, the anode plate of the holder parts 309, 312, and 313 and the cheeks 350 and 351 of the tongs 344, 345 are crimped around this mandrel and, with their bent ends, are positioned in the correct position relative to the wires a. The lever 377 with the welding device is brought to the working position, the pins 371 and 372 move towards each other and the anode plate is welded to the wires of the leg K. After this, the mandrel 314 is moved downwards, while the welding device is lifted and the leg k is supplied by the moving part 2 of the machine to the position N.

The final step of attaching the incandescent wire is to device H (Fig. 1). This device is driven by a sprocket 400 mounted on shaft 401. Another gear wheel 402, fist 403, and cam discs 404 and 420 are mounted on shaft 401 (Fig. 23-24). The support 406 is fixed on the base 1, to which the lever 408 is pivotally attached. This lever 408 is attached to the hinge 407 by a rod, which is guided by a slot in the base 1 and is controlled by means of the roller 410 with a fist 403. The lever 408 has a spindle with a 405 fork with a pin 411 pins 412 and is under the action of the spring 409. The pin 412 is guided by the clutch on the bracket 417 and ends with the cannula 413, through which the wire 414 is passed, winding the drum 415 attached to the bracket 417. In FIG. 25, this part of the mechanism is described in more detail. about. As can be seen from FIG. 25, the peg 411 is connected to the pin 412 by a hinge 433 and provided with two protrusions 431 and 432. If the fork 405 of the lever 408 is pushed to the right, then the protrusion 431 will clamp the wire 414 fixedly. When the needle 413 is in the lower position

This overhang, the wire 414, is gripped by the tongs 419 (Fig. 23). Pincers 419 can rotate on axis 416 fixed to base 1 and are driven by means of a roller sliding along cam 420. The cheek of these pincers is provided with a felt pad and is pressed, in the pinched position of the pincers, to the fixed stop 440 by a spring. The wire 414 is gripped between the anvil 440 and the hub 419, and when the pin 412 is fed upwards, it comes to the position necessary to attach it to the hooked ends of the supporting wires from the leg. Pincers 421 and 422 with cheeks 423 and 424, driven by a fist 425, are provided for squeezing these hooked ends. This arm, which sits on the same shaft 426 with gear 427, is driven by a gear wheel 402. Cheeks 423 and 424 at the upper ends are provided with flat portions along which knives 435 and 436 can slide to cut the wire 414 after attaching it to the feed wires. The knives 435 and 436 are attached to the lever 418, which is rotatably fixed at point 437 and is controlled by means of a roller by a paw disc 44.

When the wires are cut, the cheeks 423 and 424 are expanded, and they are pulled back in the unfolded position, so that they do not interfere with the movement of the leg k to the normal position O. In the O position, the worker removes the finished leg with attached electrodes from the holder and replaces its other, which in turn, undergoes the operations described above.
