201 Wire coiling machine US201204 1980-10-27 US4372141A 1983-02-08 Frank S. Russell; Robert J. Simonelli
A machine for coiling wire to form any one of a number of different size, type and configuration of coil spring and comprising a machine frame in which is mounted a driveshaft, intermediate shaft, camshaft, and feed roller shafts. At the work station of the machine appropriate coiling dyes are supported along with one or more cutters mounted adjacent thereto. The wire is fed to the work station via a pair of feed rollers driven at variable speed, preferably by means of an elliptical gear drive, wherein the feed speed is at a maximum during coiling and decrease to a minimum feed speed for cutting. Wire feed is synchronously interrupted at cutting by means of a cam arrangement that briefly disengaged the feed rollers. This variable speed drive enables a high duty cycle of operation and also enables start up (feed rollers engaging) at reduced speed so as to minimize wire distortion. In an alternate form of wire feed, instead of interrupting drive to the feed rollers by a cam arrangement, a clutch is used to briefly stop motion for cutting.

203 NC Coil spring manufacturing apparatus US784917 1977-04-05 US4112721A 1978-09-12 Hirobumi Takase; Yutaka Utsunomiya
The NC coil spring manufacturing apparatus of this invention is an apparatus for manufacturing a variety of coil springs according to predetermined programs controlled by instruction signals transmitted from a microcomputer, comprising a pitch feed mechanism for enabling a pitch tool to start and stop quickly for and at an end turn processing position, a diameter tool feed mechanism for enabling a coiling point to shift quickly against the thrust by an element wire, a means for digitally measuring the dimensions of a wound coil spring, and a means for selecting the coil spring according to the result of such measurement, and employing a pulse motor for driving feed rollers for element wire, controlled by the computer and requiring only a simple control circuit; thus manufacturing precise and uniform coil springs efficiently.
204 Wire coiling machine fluid cutoff US783945 1977-04-01 US4090425A 1978-05-23 Stephen A. Platt
Wire coil cutoff apparatus for a wire coiling machine that forms an axially advancing, rotational, helical wire coil, the advancing coil being momentarily biased into indexing engagement with the cutter blade by pneumatic pressure, and the indexed blade then being shifted into cutoff relation with the coil while the pressure is still applied.
205 Spring coiling machine with auxiliary drive and control US577617 1975-05-14 US4026135A 1977-05-31 George Joseph Yagusic; Bernard Pierre Lampietti
A spring coiling machine with an auxiliary drive and control has a feed roll driving clutch with inputs from both a main machine drive and from the auxiliary drive. The main drive is set to rotate feed rolls to advance a length of wire an increment less than that required for a coil spring of a predetermined configuration and dimension. The final increment of wire feed is then accomplished by the auxiliary drive, the clutch acting to render the latter effective as main drive rotational velocity drops off. An optical sensor responsive to the position of a leading end portion of the wire in the spring being coiled thereafter signals the auxiliary drive control to terminate wire feed. A fast response servo motor is employed as an auxiliary drive and a precise termination of wire feed is thus achieved to provide for precise end positioning. The clutch employed is unidirectional and termination of auxiliary feed may be accomplished by terminating forward drive or by reversing the servo motor. A bistable device maintains an "on forward drive" signal pending receipt of an "off forward drive" or "reverse" signal, the latter being supplied by said optical position sensor. The "on" signal for the servo motor may be provided in either event by a cam shaft position sensor operable when a main drive actuated wire feeding operation is partially complete.
206 Spring winding machine with improved pitch mechanism US621209 1975-10-09 US4018071A 1977-04-19 Bernard Pierre Lampietti
A spring winding machine comprising a rotary cam shaft, a cam mounted on the shaft and rotatable therewith, and a follower on a lever intermediate its ends and engaged and driven in one and an opposite direction by the cam during each cam rotation. The lever is pivotally supported at one end and an opposite end drives a first slide in one and an opposite direction. A rack on the slide rotates a pinion on one and an opposite direction which in turn drives an electrical spindle drive means. The drive means includes a direct current tachometer generator and a fast response servo controller and motor which rotates the spindle in one and an opposite direction to wind springs thereon. A manually adjustable potentiometer predetermines the number of spindle turns for each cam rotation and thus establishes the number of spring coils. A second slide movable in one and an opposite direction is driven from the first slide by means of an angularly adjustable guideway on the first slide and a follower on the second slide. Adjustment of the guideway occurs about a point on the centerline of movement of the second slide so that a constant reference or starting point is maintained. The second slide drives an oscillable lever which in turn drives a conventional pitch rod in one and an opposite direction. The pitch rod is connected by a yoke with the spindle for free relative rotation but for axial driving movement of the spindle by the rod. Thus, the amount or extent of spindle axial or pitch movement is determined by the angular adjustment of the guideway and a constant starting point is provided for to maintain a constant wire feed or pass line, spindle readjustment for each pitch setting being thus eliminated.
207 Machine for manufacturing wire coils US583058 1975-06-02 US3972214A 1976-08-03 Adolf Jagersberger
In a machine for manufacturing wire coils, wire is fed by a feeder and is shaped in a winding station to form a continuous helix the convolutions of which may adjoin each other or may be spaced predetermined distances apart. This continuous helix is cut by cutting means into wire coils having a predetermined length or number of convolutions. These coils may constitute springs or may preferably constitute electric resistance heating coils. To control the length of the wire coils, a sensing wheel is associated with the winding station and is driven by the wire and operates control means for controlling the cutting means in such a manner that the length of each severed coil is determined by the preset, measured wire length. To ensure an exact length measurement, the control device comprises a pulse generator, which is operated by the sensing wheel and produces pulses in dependence on the angular movement of the wheel, and a presettable counter for counting these pulses and for initiating the operation of the cutting means when a preset number of pulses have been counted.
208 Method for producing coil springs US47142274 1974-05-20 US3906766A 1975-09-23 SATO TAKASHI
In a method for producing coil springs, an electric pulse is generated for every predetermined length of wire fed through a wire feeding mechanism; a predetermined number of these pulses, which are adapted for the production of the shape and dimensions of a coil spring, are applied at a time also adapted for the formation of the shape and dimensions of the coil spring, to at least one of a pitch controlling circuit, a wire length controlling circuit, and a coil diameter controlling circuit all included in a control device; and the output of the control device is utilized for controlling at least one of a pitch forming device, a wire feeding device, and a coil diameter regulating device, and also a wire cutting device, whereby the shape and dimensions of the coil springs are controlled numerically.
209 Coil transfer and storage tool and machine for winding same US3714973D 1971-02-08 US3714973A 1973-02-06 KIEFFER V; KORSKI F
An apparatus for winding and a method for storing electrical coils used in the axial insertion of motor windings provides for placing the winding coil on a transfer and storage tool in a manner similar to that required for axial insertion. The tool is inverted and the coil is transferred to an axial insertion machine prior to placement in a stator core. The tool preferably is an injection molded plastic, form, with a series of blades arranged similarly to the blades of the axial inserter. While prewound coils may be placed on the tool manually, the apparatus of this invention winds successive coil throws and automatically places them on the transfer and storage tool.
