By connecting to the control circuit of one or another number of BVK, the number of pulses coming to the stepping motor and thereby change the pitch of the wire on the coil.  Drive sprockets 28 and 31 of the pickup mechanism are seated on shaft 34, and followers 30 and 33 are fixed on rails 12 and 13 or on housing 35. Platform 11 is directly attached to chains 29, 32, the tension of which is controlled by sprockets 36 and 37.  The platform 11 is secured with a flag 38, which interacts during its movement with the BVK 39-41 located in the path of its movement, the BVK 39 and 40 are intended to change the direction of movement of the exhaust mechanism along the coil and control the course of the layout.  At their command, the direction of rotation of the stepper motor 26 is changed, the BVK 40 is also used to control the coil replacement process. In the wire transfer mode, the BVK 39 is simultaneously a sensor for a pulse counting relay (RCI) (not shown), BVK 39 and 40 are fixed on carriages 42 and 43. Their position relative to the coil cheeks can be changed with the help of screw pairs 44 and 45 and the handle 46 and 47.  .  The BVK 41 is fixed on the device case 35 and is intended for duplicating the functions of the BVK 40 c.  the mode of transferring the wire to an empty coil, as well as for automatically stopping the drawing machine and the coiler when the latter is not prepared to transfer the wire.  The pickup coils are mounted on a movable carriage 48, which is reciprocally movable on rolling bearings along the guides by means of an air cylinder 49 mounted on a fixed rod 50 between the guides 12 and 13. On the carriage 48 there are two cylindrical rods 51, 52 to the supporting platforms 53 and 54 designed to base the coils thereon.  The distance between the rods 51 and 52 is assumed such that when one of the coils is installed in the work zone (winding zone) of the other is available for replacement.  The coils are fixed by means of wedge-screw clamps 55, 56 placed in the base rods 51, 52, the screws of which are rotated by the knobs 57, 58 manually or by means of the stops 59, 60, 61 mounted on the path of the movement 57, 58 On the pneumatic cylinder 49, flags 62, 63 are fixed, interacting alternately with BVK 64, 65 and 66 placed in the path of their movement.  BVK 64 and 66 are designed to control a spool-type device (not shown) that serves to supply air to one or the other cavity of pneumatic cylinder 49, and BVK 65 to control the presence in the working area of the receiving coil and issue a signal to the automatic wire transfer in case if involved BVK 40.  BVK 40 gives the command to transfer with time delay, which is installed on the relay.  of time.  This shutter speed is assigned based on the condition of providing the necessary number of turns of wire on the winding.  digging drum 67 and accumulative drum 5 of the exhaust mechanism in overshoot mode, when the exhaust roller 3 goes beyond the winding zone, as well as to sufficiently remove it from the end surface of the drum 67 to eliminate the possibility of their collision when the filled coil moves from the working zone .  A storage drum 67 is inserted by the base portion into the opening of the coil.  The coils that are reeled on the accumulation drum 67 are used as a spring damper, which makes it possible to eliminate the twisting or breakage of the wire in the idle mode of a pulling mechanism.  The outer diameter and height of the drum 67 are selected on the basis of the length of the damped wire section.  In order to control the winding speed, the device is provided with a loop left regulator 68 consisting of fixed and movable roller blocks 69. This regulator is also used as a wire storage device.  Its movable unit moves along rails 70, 71 and is associated with interchangeable weights 72 and a helical bar 73, which is connected to a loop-length sensor.  For example, selsyn 74.  When moving the rolling block of rollers from one extreme position to the other, the rail 73 rotates by the required angle, and with it the selspin's pore 74.  On the carriage of the movable block 69, the flag 75 is fixed, which interacts with the BVK 76 and 77, which serves to stop the winding device and the drawing machine in those cases when the block 69 reaches one of their positions.  On platform 11, on rolling bearings, a hollow arm 78 is fixed, braked when necessary by brake 79.  The leash 78, combined with the accumulative drum 5 of the stretching cylinder 1, serves to accumulate the turns and to keep the wire from moving it in the direction of the loop regulator 68 in the transfer mode to the empty reel.  The driver 76 in the operating mode is driven by the rotation of the wire being pulled through its rollers 80 and rotates in the non-braked state together with the exhaust cylinder 1.  The leash can be made with forced rotation.  In this case, it is supplied with an individual drive.  In this case, it is possible to eliminate the twisting of the wire in the transfer mode in the area from the exhaust roller 3 to the filled coil, for which it is enough to stop the exhaust cylinder 1 with the rotating leash 78. The wire coming from the looper regulator 68 accumulates on the stationary storage drum S cylinder 1 in the form of spiral turns.  With a non-driven lead 78, the accumulation of wire on the drum 5 of cylinder 1 is carried out with the braked or completely stopped driver 78 and the rotating cylinder 1 due to the winding of the wire on the drum 5. The construction of the accumulator drum 5 of the multiplier allows the wire to be pulled through it.  accumulate or reset.  To accumulate the wire and dump it from the drum 5, you can do without the lead 78.  To do this, it is sufficient to set the roller 81 so that in the transfer mode the wire leaves it tangentially to the storage drum 5, and in the reset mode it moves over the drum 5 to the point from which the wire running down it describes the conical surface most favorable for shaking. accumulated turns from the drum 5.  To provide such a mutual arrangement of the roller 81 and the drum 5, the reciprocating movement of the exhaust mechanism in the transfer mode or the forced movement of the roller 81 can be used.  one of the above provisions.  Preparation of the device for operation is performed as follows.  Cylindrical rods 51, 52 and supporting surfaces 53, 54 are used to base the coils on the carriage 48.  Coils are mounted alternately.  After installing the first of them, the cart is moved from one extreme position to the other by means of an air cylinder 49.  When the second Katugaki is fed into the working area, it is secured with a wedge screw mechanism 55 (56) when its handle 57 (58) interacts with the stop 60.  In order to prevent the coil being fed into the working area from bumping into the exhaust cylinder 1 and roller 4, the platform 11 is set to the extreme upper position.  This is characteristic of the beginning of the mode of wire transfer from one coil to another with the installation of the exhaust roller 3 in one of the extreme diametrically opposed positions relative to the catalog, excluding the possibility of their meeting.  From the retractor (dragging machine), the wire is guided to the take-up reel through a loop controller 68, the deflecting rollers 80, 81, the guide rollers 2 of the exhaust mechanism and the exhaust roller 3, and fix its end on the rod.  When the coils are mounted on the trolley 48, accumulative drums 67 are inserted into them from above. Depending on the size of the coils and the cross section of the wire to be wound on them, a rammer pickup step (stepper motor) is used, including a number of pulse sensors (proximity switches). , and the stroke of the platform 11, equal to the distance between the cheeks of the coils, using screw pairs 44, 45 and the handle 46, 47, set the contactless switches 39, 40 to the required position.  On the sensor of the number of layers, the number of pairs of layers known for cutting the wire and the size of the coil is established, which must be wound on the coil.  The movable block of the rollers of the loop controller is set in the upper position.  Engines 22 and 26 are turned on by the exhaust mechanism and pickup mechanism from the loop controller 68 at the same time as the delivery device is put into operation.  The required amount of tension of the wire during winding is set by means of interchangeable weights 72 associated with the moving unit 69 of the loop speed regulator.  When the electric motor 22 is turned on in the work of the exhaust roller 3 and the driver 78, a rotational movement around the fixed coil, on which the end of the wire is fixed, is communicated. also reciprocating motion in the pickup mode along the coil from the stepper motor 26, operating in the mode given by the pulse sensor 27 associated with the electric motor 22 controlled from the loop regulator 68. In this case, the rotational motion of the exhaust mechanism is communicated from the electric motor. . . 22 4Q res. belt drive 23, 24, 25. , the drive shaft 21, the hollow pulley 10 and the belt drive 10 6, 1, and the reciprocating from the stepper motor 26 through chains 28, 29, 30 and 31, 32, 33, Change the direction of rotation, the stepper motor 26, and therefore , and the direction of movement of the platform 11 occurs on command from the limit switches 39, 40 when interacting with the flag 38, If necessary, adjusting the progress of the marker pro. is shifted on the move, by changing the position of the contactless limit switches 39, 40 with screw pairs 44, 45 and handle 46, 47. As the wire coil is filled, the leveling of the winding speed and the wire arrival speed from the wire drawing machine is equalized torus 68 controlling the motor i.  In cases where the loop 75 knob 75 acts on the BVK 76 (77), the drive of the drawing mill and the coiler is automatically disabled.  The proximity switch 39 is used as a layer-by-layer sensor for monitoring the filling of the coil with wire.  For each turn of platform 11 up and down, t. e.  after winding on the card of every two layers of wire, the switch interacts with the flag 38 and gives a signal to the RSI, which is triggered after winding a predetermined number of layers of wire on the coil and switches to work in coil change mode (BVK) 40. Upon reaching the flag 38 of the BVK 40, the platform 11 does not change its movement to the opposite, but moves up until the moment the flag 38 enters the shed of the BVK 41, which in this case duplicates the BVK 40 and changes the direction of movement, the platform 11 to the opposite o when the platform 11 moves upwards, the flag 38 interlocks with the BVK 40, on command of which, with a time delay sufficient to move the pneumatic cylinder 49 and braked by the brake 79 to the required distance from the upper cheek of the coil of the exhaust roller 3 Doc 78, as a result of which the drum 5 winds up a wire.  The ejector roller 3, lifting above the filled coil, winds on the accumulation drum 67 a predetermined number of turns of wire, which are subsequently pulled out from it and used as a damper, which prevents the wire from twisting when the exhaust mechanism rotates in idle mode when replacing the filled coil on empty.  During operation of the exhaust mechanism in idle mode, t. e.  when the winding of turns on accumulative drum 67 stops, at the time relay command, the pneumatic cylinder 49 removes the filled coil from the winding zone, and replaces it with an empty one.  When the trolley 48 is moved from one extreme position to the other from the sip of the BEC 65, the flag 62 is displayed and the flag 63 is entered.  When the filled coil is moved from the working area, the turns of the wire, pulled by the exhaust mechanism from the storage drum 67, under the action of the self-weight are lowered, as the movement of the relaxed wire in the direction of the loop loop prevents the coils wound on the storage drum 5, an increase in the loop length (wire margin) on the loop controller in this case occurs due to its arrival from the dragging machine.  A safety clip 82 prevents the wire from escaping from the groove of the 3 B wire roll to e transfer to an empty spool.  The electric system of control of the device operation modes provides for automatic stopping of the drawing machine and the winding device.  The automaton works if, when the flag 38 is applied to the BVK 41, the coil is not fed into the working area.  The fact that the coil replacement operation has been completed is signaled by the BVK 65, having been impacted by the flag 62 or 63 when the cart is moved from one extreme position to the other.  After supplying an empty coil to the winding zone, as a result of which BVK 65 is involved, BVK 41 commands to turn off brake 79 and change the direction of rotation of stepper motor 26 and move platform 11 to pickup area, as well as to switch BVK 40 to work in layouts.  As the loop increases on the loop controller 68, the control action of the selsyn 74 on the electric motor 22 increases, which accelerates in the jib mode to a speed corresponding to the speed of the wire from the transmitter.  After the exhaust roller 3 is thrown onto the empty coil of the first turn, the process of winding a wire drawn through the storage drum 5 of the cylinder 1 on it begins.  In this case, the lead is driven by the wire pulled through it rapidly into rotation and gradually removes the accumulated turns from the drum 5, further rotating together with the exhaust cylinder 1.  After the command to transfer the RCI resets the account and keeps records of the filling of the wire following the coil.  The filled coil is replaced with an empty one, and the cycle is repeated.  Before replacing the coil, a section of wire binding the filled and filled coils is cut with scissors embedded in the cart 48.  A storage drum 67 is removed from the filled coil and inserted into the empty reel mounted on the cart 48.  When the wire is wound on stationary coils using the above-described device, it twists on the Zbo for each turn of the exhaust d-lindra 1.  By unwinding the wire from these fixed coils, the stranding is eliminated.  The ends of the wire of the two coils can be connected, t. e.  to carry out its continuous return, since both ends of the wire of each coil are brought out.  The proposed device allows for the continuous winding of the wire on m over-coil with the maximum degree of mechanization of all operations with minimal energy costs for the winding process.  The use of an exhaust mechanism in the form of a cylinder suspended on the belts will allow an increase in the winding speed and thereby expand the range of use of the device.  Claim 1.
