Definitions
- the present invention relates to coiling machines. More specifically, the present invention is concerned with a machine to coil semirigid wire without using a core, resulting in a free-standing coil.
- Coiling machines are well known in the art. They usually are provided with a rotating core onto which wire is wound. In some cases, the core is part of the finished product. When this is the case, the coil is completed when a predetermined number of turns have been coiled thereto.
- the core is not part of the finished product.
- the coil has to be removed from the core.
- the core may be made of separable sections so designed as to allow the reduction of the core dimensions thereby facilitating the removal of the core from the coil.
- An object of the present invention is therefore to provide an improved coiling machine for coiling rectangular wires and other relatively large non-circular wires.

- the present disclosure is concerned with a coiling machine configured to coil semi-rigid wires without using a core to wind the wire thereonto, yielding a free-standing coil.
- the wiring machine includes a wire drawing mechanism, a wire feeding mechanism and a wire bending mechanism all controlled by a controller.
- the wire feeding is so controlled as to feed a predetermined length of the continuous wire from the wire drawing mechanism to the wire bending mechanism prior to the bending of a predetermined angle. This process is repeated until the coil is completed.
- the coiling machine 10 includes a wire drawing mechanism 12, a wire feeding mechanism 14 and a wire bending mechanism 16 all controlled by a controller 18 provided with an interface 19.
- a transparent cover 20 is removably positioned over the wire feeding mechanism 14.
- the purpose of the wire drawing mechanism 12 is to uncoil a certain length of wire from the spool 22 in order to supply the wire to the feeding mechanism 14 at a generally constant and moderate tension.
- the wire feeding mechanism 14 then feeds a precise length of wire to the wire bending mechanism 16 that precisely bends the wire of a predetermined and controllable angle.
- the controller 18 controls these mechanisms so that a sequence is followed to yield a coil, such as coil 132 in Figure 21 , having the desired specifications and geometry.
- the wire drawing mechanism 12 includes a shaft 24 onto which the spool 22 is mounted.
- the shaft 24 is maintained to a frame 26 of the machine 10 via two pillow blocks 28 and 30.
- the shaft 24 includes a pulley 25 used to connect the shaft 24 to a motor 27 via a driving belt 29.
- the motor 27 is coupled to the controller 18 so that the controller 18 may control the unwinding of the wire from the spool 22 via the motor 27.
- the shaft 24, motor 27 and driving belt 29 can be replaced in parts, in whole or complemented by other spool driving means controllable by the controller 18.
- the wire drawing mechanism 12 also includes a movable carriage 32 mounted to rails 34 via linear bearings 36 to allow longitudinal movements (see arrow 38) of the carriage 32 relative to the spool 22.
- the movable carriage 32 includes an arcuate wire guide 42 including two parallel plates 44 spaced by rollers 46.
- a pneumatic cylinder 40 biases the movable carriage 32 away from the spool 22 to keep a tension thereon.
- the cylinder 40 is a closed circuit. Limit switches (not shown) are used to supply carriage position data to the controller 18.
- the carriage 32 allows supplying wire to the feeding mechanism 14 at a constant level relatively thereto.
- the movable carriage 32 further allows supplying the wire to the wire feeding assembly 14 at a generally constant and moderate tension by automatically adjusting the tension on the wire, following the spool 22 unwinding a certain length of wire.
- limit switches (not shown) detect the limit position of the carriage 32, a signal is sent to the controller 18 which activates the motor 27 for unwinding another length of wire. This process is repeated so that the wire feeding mechanism 14 always has a sufficient length of wire for its operation.
- the carriage 32 further prevents the wire feeding assembly 14 from having to pull the full or variable load of the spool 22.
- the wire drawing mechanism 12 also includes an adjustable wire straightener 48 that straightens the drawn wire before supplying it to the wire feeding mechanism 14.
- the adjustable wire straightener 48 includes bottom rollers 50 and top rollers 52 adjustably biased towards the bottom rollers 50. It is believed that this type of straightener is know in the art and will therefore not be discussed in greater details herein. Of course, the straightener can have other form allowing to straight the wire.
- drawing mechanism according to the first illustrated embodiment of the present invention includes a carriage 32 which provides for both the above-described tensioning and leveling functions
- a drawing mechanism according to a further embodiment of the present invention can be provided with two separate mechanisms, one for the leveling function and the other for tensioning the wire drawn from the spool 22.
- any biasing pulley appropriately mounted to the frame can be used to insure that the wire is leveled with the feeding mechanism 14.
- the wire straightener 48 can also play the role of such leveler.
- Figure 5 of the appended drawings illustrates the wire feeding mechanism 14 and the wire bending mechanism 16.
- the purpose of the wire feeding mechanism 14 is to repeatedly feed predetermined lengths of the wire to the bending mechanism 16 under control of the controller 18 to yield a coil having predetermined dimensions.
- the wire feeding mechanism 14 includes an elongated wire guide 72 to guide the wire 70 from the wire drawing mechanism 14 to the wire bending mechanism 16 and a wire feeder 53.
- the elongated wire guide 72 includes a slot 73 configured and sized to receive the wire 70.
- the wire feeder 53 includes a linearly movable table 54 actuated by an electric servo motor.
- a linearly movable table 54 actuated by an electric servo motor.
- the table 54 may therefore move in the directions of arrow 55 under the control of the controller 18. It is to be noted that the movable table 54 is shown at its leftmost position in Figure 5.
- a gripping arm 56 is pivotally mounted to the movable table 54.
- the gripping arm 56 is fixedly mounted to a shaft 58 pivotally mounted to two pillow blocks 60 (only one shown) which are secured to the table 54.
- the first end 62 of the arm 56 is further pivotally mounted to an actuator 64 that is itself pivotally mounted to the table 54. Accordingly, the actuator 64 may pivot the arm 54 about the shaft 58 (see arrow 59 in Figure 6).
- the second end 66 of the arm 56 includes a friction pad 68 configured to positively and frictionally engage the wire 70 onto the wire guide 72 when the arm 56 is in the wire gripping position, shown in broken lines in Figure 6.
- a friction pad 68 configured to positively and frictionally engage the wire 70 onto the wire guide 72 when the arm 56 is in the wire gripping position, shown in broken lines in Figure 6.
- the wire bending mechanism 16 will now be described in more detail with reference to Figure 7.
- the mechanism 16 includes a wire holding assembly 74 for selectively immobilizing the wire 70 during the bending process and a wire bending assembly 76 for bending a selected portion of the wire 70.
- the wire holding assembly 74 includes a bracket 78, defining a wire-receiving support, to which is mounted an actuator 80 provided with a piston 82, defining a movable friction element, that may slide through an aperture of the bracket 78.
- the assembly 74 also includes a channel element 84 provided with a longitudinal channel 85 configured and sized to receive the wire 70 and defining a fixed friction element, and a top plate 86 interconnecting the element 84 and the bracket 78.
- the wire 70 is prevented from moving when it is frictionally engaged by the piston 82 when it is extended through the aperture of the bracket 78.
- the wire holding assembly 74 may be oriented differently relatively to the wire bending assembly 76 than what is illustrated in Figure 7. For example, the wire holding assembly 74 as illustrated in Figure 7 could be turned upside down.
- the wire bending assembly 76 includes a base 87 secured to the frame 26, a fixed roller 88 fixedly mounted to the based 87 and a pivotable roller 90 that can pivot about a pivot axis defined by the fixed roller 88. More specifically, the pivotable roller 90 is fixedly mounted to an actuator 92, which is mounted to the base 87. Both the rollers 88 and 90 include circumferential channels, respectively 89 and 91 , sized to snugly receive the wire 70.
- a predetermined geometry of coil is achieved by successively feeding a predetermined length of wire and then bending the wire of a predetermined angle and then repeating these two steps as necessary with a series of lengths and angles.
- Figure 8 illustrates the feeding (see arrow 94), by the wire feeding mechanism 14, of a first predetermined length of wire.
- This first length of the wire fed is equal to the length of the first long leg of the coil plus the length of the lead of the coil.
- the wire feeding mechanism 14 stops and the piston 82 is actuated to prevent wire movement.
- the pivotable roller 90 is pivoted (see arrow 94)
- the radius of curvature of the bend is equal to the radius of the channel of the fixed roller 88.
- the gap between the fixed and pivotable rollers 88 and 90, including the circumferential channels 89 and 91 is such that the wire 70 is snuggly fitted between the two rollers 88 and 90, allowing for a precise bending.
- the roller 90 is returned to its resting place by the actuator 92 (see arrow 98), the piston 82 returns to its resting position and a second predetermined length of wire 70 is fed (see arrow 100) by the feeding mechanism 14. Again, when the precise length had been fed, the wire feeding mechanism 14 stops and the piston 82 is actuated to prevent wire movement. It is to be noted that this last step is similar to the step illustrated in Figure 8, where only the second predetermined length of wire fed to the bending mechanism 14 differs from the first predetermined length of wire.
- piston 82 is actuated to prevent wire movement during the bending process and returns to its resting position while wire is fed to the bending mechanism. For concision purposes, these movements of the piston 82 of the actuator 80 will not be repeated hereinbelow.
- Figure 11 illustrates the bending of the second bend of the coil.
- the pivotable roller 90 is pivoted (see arrow 102) of a second predetermined angle. It is to be noted that while the bending radius of the second bend is the same as the bending radius of the first bend, since it is the fixed roller 88 that determines the bending radius, the angle formed by the second bend is smaller than the angle formed by the first bend since the movement of the pivotable roller 90 is greater in the second bend. [0064] As can be seen from Figure 12, the pivotable roller 90 returns to its original position (see arrow 104) and a third predetermined length of wire is fed (see arrow 106).
- the third predetermined length is equal to the second predetermined length and the third bend is identical to the first bend in order to yield a coil 132 as illustrated in Figure 21.
- the process may then be repeated a predetermined number of times to yield a coil having the predetermined number of turns.
- the first predetermined length or wire fed to the bending mechanism 16 is of course less than for the first turn since no additional length has to be provided for the length of the lead of the coil.
- a rectangular wire coiling machine 134 according to a second illustrative embodiment of the present invention will now be described with reference to Figures 22 to 24. Since the machine 134 is very similar to the machine 10, and for concision purposes, only the difference between the two machines 10 and 134 will be described herein in more detail.
- the wire coiling machine 134 further comprises a wire stripping mechanism 136 and a wire cutting mechanism 138.
- the wire stripping mechanism 136 is mounted to the frame 26 between the wire drawing mechanism 12 and the wire feeding mechanism 14. However, as will become more apparent upon reading the following, the wire stripping mechanism 136 can be located anywhere downstream from the spool 22 and upstream from the wire cutting mechanism 138. Of course, the wire stripping mechanism 136 is also operatively position relatively to the wire.
- the wire stripping mechanism 136 includes two opposite stripper claws 138 mounted to a common stripper claw actuating mechanism 140 which is slidably mounted to a frame member in the form of a beam 141 , two grater fingers 142, each one mounted to a respective stripper claw 138, a wire clamping mechanism 144 secured to the beam 141 , a linear actuator 146 for selectively moving the stripper claw actuating mechanism 140 along the beam 141 and a vacuum (not shown).
- the beam 141 is parallel to the elongated wire guide 72 of the wire feeding mechanism 14.
- Each stripper claw 138 is pivotally mounted to a mounting assembly 148 part of the stripper claw actuating mechanism 140 via respective interlocking gears 150 for pivotal movement in unison between a resting position and a wire engaging position.
- the stripper claws 138 are positioned relative to the wire feeding path so as to be symmetrically facing each other relative to the wire 70.
- Each stripper claw 138 includes a cutting edge 139 at its distal end.
- the stripper claw actuating mechanism 140 further includes a lever arm 152 integrally mounted to one of the two stripper claws 138 and an actuator, in the form of a cylinder 154, operatively coupled to the lever arm 152. More specifically, the distal end 156 of the lever arm 152 is pivotally mounted to the piston 158 of the cylinder 154.
- the cylinder 154 is mounted to the mounting assembly 148 via an L-shaped bracket 160.
- the stripper claw actuating mechanism 140 is slidably mounted to the beam 141 via sliding elements 162 and 164 secured to the beam 141 and an L-shaped bracket 166 securing the mounting assembly 148 to the sliding element 164.
- the linear actuator 146 includes a cylinder 167 whose piston
- the piston 168 is coupled to the sliding element 164 for selectively causing reciprocal relative movement of the sliding elements 162-164. More specifically, the piston 168 is fixedly mounted to the first longitudinal end 170 of an elongated plate 172, the second longitudinal end of which being secured to the sliding element 164 via a length-adjustable bolt 174. Two mechanical stops 176-178 are secured to the beam 141 for limiting the course of the stripper claw actuating mechanism 140 along the beam 141.
- Each grater finger 142 includes a blade 180 at its distal end.
- Each grater finger 142 is mounted to a respective stripper claw 138 so that its blade 180 is leveled with the cutting edge 139 of the stripper claw 138 when the stripper claws 138 are in the wire engaging position.
- the wire clamping mechanism 144 includes a first friction plate
- the clamping actuator assembly 186 includes a cylinder 188 mounted to the beam 141 via a mounting bracket 190.
- the piston 192 of the cylinder 188 is coupled to the second friction plate 184 via an adjustable-length assembly 194. Since such adjustable-length assembly is believed to be within the reach of a person skilled in the art, and for concision purposes, it will not be described herein in more detail.
- the stripper claw actuating mechanism 136, the wire clamping mechanism 144, and the linear actuator 146 are all controlled by the controller 18.
- Figure 27 illustrates the wire stripping mechanism 136 in a resting position with a wire 70 passing between its stripper claws 138. According to this position, the cylinder 154 of the stripper claw actuating mechanism 140 is fully extended, the claws 138 are apart from one another, and the cylinders 167 and 192 of respectively the linear actuator 146 and the wire clamping mechanism 144 are fully retracted.
- the stripper claw actuating mechanism 140 is also actuated, resulting in the retraction of the piston of the cylinder 154 (see arrow 198). This raises the lever arm 152, closing together and onto the wire 70 the two stripper claws 138 (see arrow 200).
- the linear actuator 146 is energized, causing the extension of the cylinder 167 (see arrow 202) which causes the displacement of the wire clamping mechanism 144 and therefore of the stripper claws 138 with the finger graters 142 attached thereto (see arrow 204).
- the linear displacement is done over a predetermined length of wire 70 so as to strip the corresponding length of wire 70.
- the finger graters 142 being positioned behind the claws relative to the stripping movement, allow removing any residual sheath and core materials 206 resulting from the stripping process.
- the vacuum (see in broken line in Figure 29) allows the removal of the residue.
- controller 18 precisely controls the operation of the wire drawing mechanism 12, of the wire feeding mechanism 14, and of the wire bending mechanism 18, and their relative positions, it can easily determine the relative position of where the wire 70 should be stripped.
- the stripper claws 138 can take other forms allowing to precisely cutting a thin layer of the wire 70.
- a wire stripping mechanism according to the present invention is not limited to rectangular wires.
- the stripper claws can be adapted to strip wires having other geometries.
- the stripper claw actuating mechanism can take other form allowing selectively bringing together and apart the two stripper claws 138. Furthermore, the two stripper claws 138 need not to be mounted on a common actuating mechanism or be movable by a common linear actuator. Indeed, separate mechanisms can be provided therefore.
- the claws 138 can be so configured and sized as to either partially or totally strip the wire 70 over its periphery.
- the wire cutting mechanism 138 includes a cutter 208 which is mounted to the frame 26 so as to be movable between a retracted position relative to the wire bending mechanism 16 and an extended position for cutting the wire 70.
- the cutter 208 includes jaw cutting elements 209 operable from the controller 18. It is to be noted that the wire cutting mechanism 138 is so configured and positioned relatively to the wire bending mechanism 16 so that the cutting elements 209 of the cutter 208 intersect the axis defined by the channel of the channel element 84 of the wire bending mechanism 16, and therefore the path of the wire 70, when the wire cutting mechanism 138 is in its extended position.
- the cutter 208 is pivotally mounted to a support bracket 210, which is slidably mounted to a frame member 212 via sliding elements 214- 216. More precisely, the cutter 208 is fixedly mounted to a post 218. The post 218 is pivotably mounted to the support bracket 210 via a pivot pin 220.
- a first cylinder 222 having its proximate end 224 mounted to the support bracket 210 and whose piston 228 is pivotally mounted to the post 218, allows pivoting the cutter 208.
- a second cylinder 230 secured to the frame member 212 allows for translating the support bracket 210 along the frame member 212. The first and second cylinders 222 and 230 are controlled by the controller 18.
- the wire cutting mechanism 138 is initially in its retracted position relative to the wire bending mechanism 16 as illustrated in solid line in Figures 33 and 34. While in this position, the top of the cutter 208 is lower than the elongated wire guide 73 and more generally to the level of the wire 70 so as to yield a clearance for the operation of the wire bending mechanism 16.
- the relative position of the cutter 208 and the wire bending mechanism 16 can be better seen from Figure 24.
- the cutter 208 is further so positioned relatively to the axis defined by the path of the wire 70 as to define an angle therewith. This allows positioning the cutting elements 209 perpendicularly to said axis.
- the wire cutting assembly 138 can be either mounted to the frame 26 or provided with its own independent support structure (not shown). The same can also be said to wire drawing mechanism 12, wire feeding mechanism 14, wire bending mechanism 16, controller 18 and wire stripping mechanism 136.
- wire coiling machines 10 and 134 have been described as having a single controller 18 controlling the operation of the wire drawing mechanism 12, wire feeding mechanism 14, wire bending mechanism 16, wire splitting mechanism 136 and wire cutting mechanism 138, a plurality of controllers (not shown) can be used to control their operation, wherein either a central controller (not shown) is used to coordinate their operation or a communication protocol is used therefore.
