Abstract

PURPOSE:To automate aligned winding of a wire on a taper bobbin incl. the time of turning by allowing a wire to reach the bobbin end for initial winding, permitting the bobbin to make traverse motion for one pitch to the reverse side after traverse motion in the amount corresponding to the delay angle, adhering the wound wire get-on part of wire having intruded in a pitch groove of the wound wire, and giving a delay angle after initial winding. CONSTITUTION:When regular winding of a wire 3 progresses to cause attainment of one side-end of a taper bobbin 2, it is moved aside in the (a) direction for a distance corresponding to the delay angle alpha so that the wire 3 becomes perpendicular to the traverse axis (i), i.e., the delay angle alpha becomes zero. Then a wire guide 6 is sunk so as to take a position nearly contacting the wire 3 side face at one side-end of the bobbin 2. Then the bobbin 2 is moved sideways in the (b) direction axially (i) for a distance corresponding to the set number of pitches, and the wire 3 is put in the specified pitch groove of the wound wire. In this condition an automatic adhering device 8 is operated to adhere the get-on part of wire 3 on the wound wire to the same with adhesives. Then the wire 3 is wound on the bobbin 2 in two or three turns by means of inching motion of the bobbin 2, which is moved for a distance corresponding to the delay angle alpha, and thus winding is conducted with delay angle given to the wire 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for winding continuously fed wire around a tapered bobbin having a truncated conical shape.

[Prior Art] In contrast to a wire rod simply wound in an aligned manner around a cylindrical bobbin, in a wire rod wound in an aligned manner around a tapered bobbin having a truncated conical shape, the wound wire rod is unwound by pulling it in the direction of the bobbin axis. This tapered bobbin aligned winding method has been adopted for a variety of applications because it operates smoothly.

In the wire alignment winding equipment that aligns and winds the wire around the taper bobbin as described above, the wire fed out from the wire feeding section is centered at the center positioning section in front of the taper bobbin, and then rotated while being perpendicular to the wire feeding direction. As shown in FIGS. 10 and 11, the wire is wound around a tapered bobbin that moves in the axial direction of the bobbin traverse by the wire winding pitch. That is, the wire rod 3 is attached to the taper bobbin 2, which is rotatably supported on the bobbin support stand 1 in the winding part at an angle such that the upper surface thereof is horizontal. (trough between) 4) and are wound in an aligned manner. At this point, the wire 3 is
In a winding operation in the intermediate portion of the tapered bobbin 2 excluding both ends, that is, in a bad steady winding operation, the winding is performed on the tapered bobbin 2 with a delay angle α.

In the above-mentioned aligned winding operation on the taper bobbin, there are relatively few problems with the steady winding operation in the middle part, but when the wire is wound and turns (changes direction) after reaching the side end of the taper bobbin, In particular, since the bobbin is tapered, the winding wire tends to become loose. For this reason, conventionally, at the time of the above-mentioned turn, a worker used a gluer to manually glue the part of the incoming wire rod that ran over the already wound wire l\ to the surrounding shoreline, and then This prevented the structure from collapsing.

[Problems to be Solved by the Invention] The conventional method of manually bonding the incoming wire to the already wound wire as described above is extremely inefficient, and it is therefore desirable to sufficiently improve the operating efficiency of the aligned winding equipment. It was impossible.

The present invention has been made in order to eliminate such conventional drawbacks, and it is an object of the present invention to provide a method for aligned winding of a tapered bobbin I\, which can automatically wind the wire on the tapered bobbin in an aligned manner, including during turning. purpose.

[Means for Solving the Problems] The present invention, which solves the above problems, provides a wire rod aligned winding method for a taper bobbin I\ for aligning and winding continuously fed wire around the outer periphery of a tapered bobbin having a truncated conical shape. The taper bobbin, which moves laterally in the direction of the bobbin traverse axis perpendicular to the wire feeding direction while rotating for winding the wire, winds the wire at a delay angle α. When the wire to be wound reaches one end of the tapered bobbin, the tapered bobbin is moved laterally by a distance equivalent to the delay angle toward the one side in the direction of the bobbin traverse axis so that the incoming wire is perpendicular to the bobbin axis. and then, a step of restraining the input wire rod at the position perpendicular to the bobbin traverse axis by the wire restraint member, and then setting the taper bobbin in a state in which the input wire rod is restrained by the wire restraint member by a length of the pig. a step of laterally moving the incoming wire rod toward the other side opposite to the one side in the direction of the bobbin traverse axis, and putting the incoming wire rod into a predetermined pitch groove of the already wound wire, and then a part of the incoming wire rod that rides over the surrounding shoreline. Next, by inching the taper bobbin, the incoming wire material is wound around the taper bobbin by a small amount, and then the tapered bobbin is moved slightly laterally toward the one side in the bobbin traverse axis direction to inject the wire. A wire rod for a tapered bobbin l\ characterized by comprising: a step of imparting a delay angle α to the wire rod; and a steady operation step of rotating the taper bobbin and moving it laterally toward the other side in the bobbin ■/rubber axis direction. This is an aligned winding method.

[Operation] According to the above-mentioned wire rod alignment winding method, the incoming wire rod is wound with a delay angle on the tapered bobbin that rotates and moves laterally toward one side in the bobbin traverse axis direction, and reaches one end. When this happens, the taper bobbin moves laterally toward the same side of the bobbin traverse axis by a distance equivalent to the delay angle, and the incoming wire becomes perpendicular to the bobbin traverse axis.
Next, the tapered bobbin is restrained in that position by the wire restraining member, and then the tapered bobbin is moved laterally in the opposite direction of the bobbin traverse axis by the set pitch, and the incoming wire enters the predetermined pre-wound wire pitch groove. Next, the part of the incoming wire rod that rides over the already wound wire is glued to the already wound wire, and then the wire rod is wound around the taper bobbin a small amount by inching operation of the taper bobbin, and then the taper bobbin - A delay angle is added to the incoming wire by moving laterally to the left by a distance equivalent to the delay angle,
Then, steady operation of the taper bobbin is performed.

Thereby, it is possible to automate the aligned winding of the wire rod on the tapered bobbin l\, including the time of turning.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 6 is a plan view of the vicinity of the wire winding section in the wire winding equipment for winding wire rods around taper bobbins in order, and FIG. 7 is a side view of the same. As shown in bobbin support stand 1
The support stand 1 is rotatably supported at an angle such that its upper surface is horizontal, and its movement in the direction of the bobbin traverse axis (a) is controlled by numerical control.

A center positioning section 4 for positioning the center of the wire 3 is installed on the upstream side of the tapered bobbin 2 in the wire rod feeding direction (left side in FIGS. 6 and 7), and a paraffin coating section 5 is installed on the upstream side in the wire rod feeding direction. Although not shown in the drawing, a wire feeding section is provided on the left side of the drawing of the paraffin application section 5.

A wire guide 6, which is a wire restraining member, a transmission type sensor 7, and an automatic bonding device 8 are arranged above the taper bobbin 2. These wire guide 6, transmission type sensor 7, and automatic bonding machine 8 are attached to an arm 9, which is screwed into a vertical screw 10 and guided by a vertical guide 11 so that it can be raised and lowered. . The screw 10 is provided on a movable head 13 of a single-axis robot 12 having a movement axis (b) parallel to the bobbin traverse axis (a), and is rotated by a rotation drive unit 14 provided on the movable head 13. By rotating the screw 10 by this rotary drive unit 14, the arm 9, the wire guide 6 attached thereto, the transmission type sensor 7, and the automatic bonding machine 8 can be raised and lowered.

The automatic bonding device 8 automatically discharges adhesive and performs other operations to bond the part of the incoming wire material 3 that runs over the already wound wire to the already wound wire, as will be described later.

The wire guide 6 is for restraining the input wire 3 at a position perpendicular to the bobbin traverse axis (ie, a position where the delay angle is zero), and the illustrated example has a simple vertical plate shape.

The transmission type sensor 7 is for detecting the incoming wire rod 3 when the wire guide 6 descends, and as shown in FIGS. It includes a light section 7a and a light receiving section 7b, and its height position is slightly above the lower end of the wire guide 6.

The center positioning section 4 has a trapezoidal guide arm 17 rotatable about a central axis 16 on a positioning section base 15, and a photoelectric switch 18a for right turn is mounted on the base 15 at the left and right positions of the guide arm 17. and has a photoelectric switch 18b for left turn, ・Guide arm 1
One slit member for following the wire rod having a vertical slit 19a through which the wire rod 3 is passed is provided at the tip end of the wire rod 7. Furthermore, two vertical guide rollers 20 whose positions are fixed are provided at the upstream end of the base 15 in the wire rod feeding direction.

The paraffin application section 5 is for applying paraffin to the wire in order to improve the slippage of the wire. In other words, during steady winding of the wire, the wire is wound in alignment with a delay angle, which causes friction between the wire and the adjacent already wound wire, but in order to reduce this friction, the wire is coated with paraffin. do. This paraffin application section 5 includes upper and lower felts 21 and 22 impregnated with paraffin,
The upper felt 21 can be raised and lowered by an air cylinder 23.

Next, the operation will be explained.

In FIGS. 6 and 7, in the steady winding operation, the wire 3 fed out from the wire feeding section as shown is coated with paraffin in the paraffin coating section 5, passes between guide rollers 20, and is set at a delay angle α. In this state, it passes through the slit 19a of the center positioning part 4 and is wound onto the tapered bobbin 2.

At this point, the arm 9 is rising, and the wire guide 6,
The transmission type sensor 7 and the automatic bonding device 8 are separated upward from the wire 3. The taper bobbin 2, which operates under the control of the numerical control device, rotates and moves laterally in the direction of the bobbin traverse axis by the wire winding pitch, thereby winding the wire in an aligned manner.

When the steady winding of the wire rod 3 progresses and the wire rod 3 reaches one end of the tapered bobbin 2, that is, as shown in FIG. 1(i).

In (ii), when the taper bobbin 2 that has been moved to one side of the bobbin traverse axis direction (direction a in the figure) reaches the state shown in the figure, the tapered bobbin 2 is moved in the same direction as above (direction a) by a distance equivalent to the delay angle α. , so that the entry wire 3 is perpendicular to the traverse axis (a) as shown in Fig. 2 (i>, (ii)).In other words, the delay angle α is zero. In this case, the slit member 19 and the guide arm 17 integrated therewith rotate around the central axis 16 following the left and right movement of the wire 3, and the left and right photoelectric switches 18a and 18b rotate in the trapezoidal shape of the guide arm 17. By simultaneously detecting the left and right edges of
It is detected that the delay angle α has become zero. Next, the wire guide 6 is lowered and positioned so as to be almost in contact with the side surface of the input wire 3 on the tapered bobbin side end side. In this case, since the transmission type sensor 7 detects the wire 3 (that is, detects the pass line of the wire), even if the pass line of the wire 3 changes due to the thickening of the wire on the tapered bobbin 2,
The lowering position of the wire guide 6 can be appropriately set with respect to the pass line of the wire.

Next, as shown in FIGS. 3(i) and (ii), the taper bobbin 2 is moved by the set pitch on the bobbin traverse axis (a).
By moving it laterally toward the other direction (direction b), the incoming wire rod 3 is put into a predetermined pre-wound wire pitch pattern. That is, the winding wire after turning is not placed in the outermost winding shoreline pitch groove of the lower winding wire, but the windings two or three furrows further inward are placed in the line pitch groove. In this state, the automatic bonding machine 8 is operated to bond the part of the incoming wire rod 3 that runs onto the already wound wire with an adhesive to the already wound wire.

Next, as shown in FIGS. 4(i) and 4(ii), the wire rod 3 is wound around the taper bobbin 2, for example, 2.3 times by four-motion operation of the taper bobbin 2 to stabilize the winding state of the wire rod 3 at the turn portion.

Next, as shown in FIGS. 5(i) and (ii), the tapered bobbin 2 is laterally moved toward one side (direction a) of the bobbin traverse axis (a) by a distance corresponding to the delay angle α, and the wire rod 3 After that, the taper bobbin 2 is set at a steady -
The machine is operated to perform steady winding of the wire rod 3.

Note that the wire rods to which the method of the present invention can be applied include electric wires, optical fibers, threads, iron wires, piano wires, and various other wires, and are not particularly limited.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to perform automatic turning when winding the wire rod in an aligned manner on a taper bobbin, thereby saving labor and reducing the operation of the wire rod aligned winding equipment. It has become possible to improve the efficiency and to stably wind the wire at the side end of the tapered bobbin.
