[Conventional technology]

A wire winding device, particularly a device for winding a solder plating wire or the like into a pack, uses a winder and a flyer attached with a pressing roller that rotates in contact with the winding pot.
A type in which a wire drawn out along with the rotation of a pressing roller falls under its own weight and is wound along a taper cap attached on a pack has been widely used.

FIG. 4 shows this wire winding device. The wire winding device includes a fixed guide pulley 2, a winding hook 3, a flyer 4, a guide pulley 5, a winding pulley 6, a holding roller 7 rotating in contact with the winding hook 3, a winding pack 8, and a winding pack 8. Consisting of a tapered cap 9 located coaxially. The winding pulley 6 and the pressing roller 7 are fixed to the flyer 4 and rotate around the winding hook 3.
The guide pulley 5 is also fixed near the axis of the flyer 4 and rotates together with the flyer 4. 1 indicates a wire, and 8a indicates a full-wrap pack.

The wire 1 supplied through the guide pulley 2 passes through the center of the take-up pot 3, passes through the guide pulley 5, and is wound around the take-up pot 3 by a take-up pulley 6 circling around the take-up pot 3, It is fed out from the pressing roller 7 which rotates in contact with the take-up pot 3, and falls along the taper cap 9 which is located coaxially with the take-up pack 8,
It is wound up by the winding pack 8. When a predetermined amount of the wire 1 is wound up by the winding pack 8 and becomes full, the full winding pack 8a is transferred to a predetermined position.

FIG. 5 is an enlarged view of the vicinity of the take-up pot 3, in which 51 is a drive motor, 52 and 53 are gears, and 54 is a hollow shaft passing through the take-up pot 3. The rotation of the drive motor 51
3 transmitted to the hollow shaft 54 via the hollow shaft 54
The flyer 4 fixed to is rotated. The flyer 4 is provided with a winding pulley 6 and a holding roller 7, and rotates together with the flyer 4. The take-up pot 3 is fixed to a fixing system 55, and the pressing roller 7 contacts the outer periphery of the take-up pot 3 and rotates. The wire 1 passes through the hollow portion of the hollow shaft 54 from the fixed guide pulley 2, passes through the guide pulley 5, and is wound around the winding hook 3 by the rotating winding pulley 6. The wound wire 1 is contacted with the take-up pot 3 by a pressing roller 7 which rotates.
And falls along the outer periphery of the taper cap 9 (FIG. 4).

[Problem to be solved by the invention]

However, according to the conventional winding device, when the winding speed is 60 m / min or more, as shown in FIG. 6, the wire 1 unwound from the winding pot 3 bulges outward from the rotary shaft due to centrifugal force. Unwinding and jumping out of the winding pack 8 made winding difficult.

Also, when the take-up pack is full (full), it is necessary to remove the full pack and replace it with a new pack. This greatly reduced the efficiency of the winding process.

Accordingly, an object of the present invention is to provide high-speed winding, for example, 60 m /
An object of the present invention is to provide a wire winding device that can normally wind a wire without jumping out of a pack wound by centrifugal force even at a winding speed of min or more.

Still another object of the present invention is to be able to continue winding even at a winding speed of 60 m / min or more without interrupting wire supply during pack switching. It is to provide a wire winding device.

[Means for solving the problem]

In order to solve the above-mentioned problem, in the present invention, a take-up pot provided above a take-up pack for taking up a wire, a pulley for winding the wire around the take-up pot, and a wire wound around the take-up pot A press roller that feeds out the wire from the take-up pan while holding down, a flyer that rotates the pulley and the press roller while maintaining a fixed positional relationship around the take-up pan, and between a take-up pan and the take-up pack. A taper cap provided coaxially with the take-up pack, a pack rotating means for rotating the take-up pack at a speed corresponding to the pay-out speed of the wire fed from the take-up pot to take up the wire, and winding has been completed. Pack moving means for moving the take-up pack and setting a new empty pack to the take-up position, and take-up between the take-up pot and the take-up pack A guide member is provided for guiding the wire that is fed out from the container and falls by its own weight, and a shutter that protrudes between the taper cap and the winding pack to hold the wire while stopping winding by the winding pack, A cutter that cuts a wire connected to the wound pack moved by the pack moving means between the shutter and the wound pack; a taper cap that can rotate together with a flyer; Means are provided to prevent rotation of the taper cap while taking is stopped.

That is, the wire winding device of the present invention has the following means or members.

(1) Take-up pot A cylindrical member fixed above the take-up pack.
It serves to form a loop of the wire by releasing the wire wound around a part of the outer periphery again.

Since a winding pulley and a flyer described below are provided below the take-up pot, a hollow shaft having a hole for passing a wire is provided through the take-up pot.

(2) Winding pulley Guide means for winding the wire around the winding hook by a pulley provided outside the winding hook, for example, at a position symmetrical to a pressing roller described below and inclined with respect to the axis of the winding hook. Act as The take-up pulley usually has a smaller diameter than the take-up pot and is provided in contact with or close to the take-up pot.

It rotates around the winding pot with the rotation of the winding pot (rotation and revolution). The positional relationship between the winding pulley and the pressing roller around the winding hook is not limited to a symmetrical position, and may be provided at a distance of, for example, 1/3 turn or 3/4 turn.

The guide pulley is provided below the take-up hook due to the suspension of the taper cap on the fryer.

(3) Pressing Roller Around the take-up pot is rotated by contact with the take-up pot (revolution and rotation) by a flyer to be described later, and the wire wound around the take-up pot is fed out. To the take-up pack located at The winding pulley and holding roller attached to the flyer always maintain a fixed positional relationship around the winding hook,
For example, it rotates at a symmetric position. The wire guided by the winding pulley is wound around the take-up pot, and is fed out from between the press roller and the take-up pot with the rotation of the press roller.

(4) Flyer As described above, the wire wound around the take-up pot by the take-up pulley is fed out from between the pressing roller and the take-up pot. For this purpose, a rotating means for rotating the winding pulley and the holding roller around the take-up hook with a constant positional relationship is required. A flyer is used as this means. For example, a flyer as shown in FIG. 5 can be used. That is, the guide pulley 5, the winding pulley 6, and the pressing roller 7 are attached to the flyer 4, and are fixed to the hollow shaft 54 penetrating the winding hook 3. The hollow shaft 54 is rotated by the drive motor 51 via gears 52 and 53.

A taper cap described later is hung below the flyer, and rotates together with the flyer. A support member for suspending the taper cap under the flyer is provided so as not to hinder the operation of the guide pulley and the passage of the wire.

(5) Take-up Pack The take-up pack is positioned below the take-up pot and a guide member described below, and is rotated by the pack rotating means to take up the wire supplied from the take-up pot.

(6) Taper cap A member having a conical or frustoconical portion provided coaxially with the take-up pack above the take-up pack. The wire guided by the guide member described later is securely inserted into the take-up pack. Guide from inside to be sent to. The taper cap may not be entirely conical or frustoconical, but may have a cylindrical portion above or below the conical or frustoconical portion. The diameter of the conical or frustoconical part (or the cylindrical part below it) is preferably equal to or slightly larger than the diameter of the core of the winding pack.
When the winding speed is high, the taper cap should be relatively long. The upper part of the taper cap may pass through the inside of a guide ring described later.

Whereas the conventional apparatus rotates the taper cap together with the take-up pack, the present invention is characterized in that the taper cap is rotated together with the flyer. This eliminates the need to separate the taper cap from the take-up pack when replacing the take-up pack, making it possible to replace the pack without stopping the operation of the apparatus. As will be described in detail later, the rotation of the taper cap is stopped while the winding is interrupted. As described above, the support member for fixing the taper cap under the flyer needs to be provided so as not to hinder the operation of the auxiliary pulley and the passage of the wire.

(7) Pack rotating means This is a means for rotating the take-up pack so that the wire unwound from the take-up pot and falling around the taper cap is taken up in a desired shape in the take-up pack. The rotation speed is set according to the winding speed so as to increase the space factor. In order to increase the space factor, it is desirable that the winding pack be vibrated up and down simultaneously with rotation during winding.

(8) Pack moving means While the winding of the wire is temporarily suspended, the winding pack that has completed winding (full winding) is moved, and a new empty pack is set at the winding position. The movement may be on a straight line or on a circumference, but movement on a circumference, for example, by a turret is convenient.

(9) Guide member A wire that is provided between the take-up pot and the take-up pack, and that is pulled out of the take-up pot and falls under its own weight, jumps out of the take-up pack by centrifugal force during high-speed take-up. Instead, it is guided so as to be surely wound into the take-up pack.

For example, it is composed of a guide ring that guides the wire on the inner circumference, or a guide ring and a cylindrical guide provided below the guide ring so as to surround a taper cap described below. When the winding speed is relatively high, it is preferable to use both.

The cylindrical guide may be rotated with the taper cap or take-up pack, but is preferably fixed. The inner diameter of the cylinder is the same as or slightly smaller than that of the take-up pack, but it is preferable that the upper part has a trumpet shape that is wider than the trunk.

Since the wire directly contacts the upper end of the guide ring or the cylindrical guide, it is necessary to use a relatively soft material. For example, soft nylon is preferable. It is preferable to use a nylon tube for the guide ring.

(10) Shutter By providing between the taper cap and the winding pack, and projecting between the taper cap and the winding pack when the winding pack is full,
Winding of the wire into the pack is suspended and the wire is suspended on the shutter. The shape of the shutter is, for example, one or more rods, branched rods, discs,
Or a grid.

The shutter is retracted from the wire path during winding and must be protruded when winding is interrupted. The movement for projecting and retracting may be linear,
It may be on the circumference. The shutter may constitute a part of a means for preventing rotation of a taper cap described later.

(11) The winding of the wire to the pack is temporarily interrupted by the cutter shutter, and after the winding is completed (full winding), the winding pack is moved by the pack moving means, and then the wire still connected to the wound pack ( (Called the transition wire) between the shutter and the full pack. When the shutter is opened after cutting, winding into a new pack is started. It is preferable to provide a guide member for guiding the crossover wire to the cutting position together with the cutter.

(12) Means for Preventing Rotation of Tapered Cap In the winding device of the present invention, the taper cap is rotated together with the flyer during the winding of the wire, but while the shutter is closed and the winding of the wire to the pack is stopped. Stop the rotation of the taper cap. For this purpose, for example, the connecting portion between the flyer and the taper cap is set to be slippable, and the connecting portion is in an engaged state during winding,
When winding is interrupted, a shutter or other braking means is brought into contact with the lower portion of the taper cap to restrain the rotation of the taper cap by friction, so that the connection portion slips and the rotation of the taper cap is stopped. I do.

In order to make the shutter abut the taper cap and restrict the rotation of the taper cap by friction, for example, a projection is provided at the lower part of the taper cap, and this projection is engaged with a recess provided on the upper surface of the shutter. There is. Alternatively, there is a method in which a convex portion is provided on the upper surface of the shutter, and the convex portion is engaged with a concave portion provided below the taper cap. In any case, the projecting and retreating movement of the shutter must be performed smoothly, so that the convex portion fits into the concave portion only at the position where the shutter completely protrudes.
For this purpose, for example, a ball plunger biased by a spring is suitable as the projection. If the ball plunger is used as a projection, the movement of the projection and retraction of the shutter is performed smoothly, and furthermore, at the position where the shutter is completely projected, the ball fits into the recess on the other side, and the engagement between the shutter and the taper cap is ensured. Done.

[Action]

In the wire winding device configured as described above, the wire is guided by a (revolution) guide pulley that rotates around the winding kettle by a flyer, is wound around the winding kettle, and is released from between the press roller. And it is fed out from the take-up pot. The fed-out wire falls by its own weight while being guided by a guide member, for example, a guide ring and a cylindrical guide member from the outside, and by a taper cap from the inside, and is accommodated in the winding pack.
Since the winding pack is rotating at a predetermined speed, the wire is wound in a circle or a petal shape therein. Whereas in conventional winding devices the taper cap is fixed or engaged with the winding pack, in the device of the present invention the taper cap rotates with the flyer independently of the pack.

When the take-up pack is full, the retracted shutter projects onto the take-up pack, the wire is temporarily held on the shutter, and the take-up into the pack is interrupted. During this time, the wound-up pack (full-wrapped pack) is moved by pack moving means, for example, a turret, and a new empty pack is supplied to the winding position. The so-called crossover wire connected to the full-pack is cut by the cutter. While the winding into the pack is interrupted, the rotation of the taper cap is also stopped by the rotation preventing means, thereby preventing the wire retained on the shutter from being dragged by the rotation of the taper cap and becoming entangled.

Thereafter, when the shutter is opened, the winding is continued again with a new winding pack. Since the wire is held by the shutter during the switching of the pack, continuous winding can be continued without interrupting the supply of the wire to the apparatus.

〔Example〕

Hereinafter, the wire winding device of the present invention will be described in detail with reference to examples.

1 and 2 show an embodiment of the wire winding device of the present invention. At the upper part of the apparatus, a take-up pot 3, a hollow shaft 54 penetrating through the take-up pot 3, and a flyer 4 are provided. It is fixed in a symmetric position. The flyer 4 is rotated by a motor 51 via gears 52 and 53. A guide pulley 5 is also fixed near the axis of the flyer 4 and rotates together with the flyer 4. A tapered cap 9 having a conical intermediate portion and cylindrical upper and lower portions is connected to a rotary guide shaft 54a fixed to the flyer 4 via a coupling 10, and is suspended. The coupling 10 is a bearing that engages by friction when the load is small and can be slipped by a large load. As shown in FIG. 3, a ball plunger 11a biased by a spring 11c is provided at the lower end of the taper cap.
Is provided. A fixed guide roller 2 for guiding the wire 1 to the center hole of the hollow shaft 54 is provided further above the take-up pot 3 and the like.

A turret 12 on which the winding packs 8 and 8a are placed is provided at the lower part of the apparatus. 8a is a full roll pack. The turret 12 can be rotated in a counterclockwise direction by rotating means (not shown).
8a can rotate counterclockwise. The take-up pack 8 is vibrated up and down by vibrating means (not shown). Close to the top of the winding pack 8, there is provided a cylindrical guide 13 of approximately the same diameter having a large-diameter lap-shaped portion at the top. Take-up pot 3 and cylindrical guide 13
A guide ring 14 is provided between them. Take-up pot 3, flyer 4, taper cap 9, guide ring 1
4. The cylindrical guide 13 and the winding pack 8 are provided such that their center lines coincide.

A shutter 15 is provided between the taper cap 9 and the winding pack 8 to temporarily hold the wire 1 when the winding of the wire is temporarily stopped, and is connected to a rotary solenoid 16 for operating the shutter. . The shutter 15 is rotatable around the rotation axis of the rotary solenoid 16, and can move between a retracted position during winding of the wire and a protruding position when winding is interrupted. It has a depression 11b on the upper surface, and engages with the ball plunger 11a at the protruding position. FIG. 3 shows a cross section of the ball plunger 11a and the concave portion 11b at the lower end of the taper cap 9 when the shutter 15 is at the projecting position.

In the vicinity of the path where the transfer wire 1a connected to the full-pack 8a passes, a cutter 17 for cutting the transfer wire 1a is driven by an operation cylinder 19 for guiding the transfer wire 1a to a cutting position by the cutter 17. Transfer wire guide arm
18 are provided. The cutter 17 is operated as required by cutter driving means (not shown).

 The operation of the apparatus according to the embodiment will be described below.

The wire 1 is guided to a winding pulley 6 via a fixed guide pulley 2 and wound around a winding hook 3. As the flyer 4 rotates, the wire 1 is discharged from the pressing roller 7. The discharged wire 1 is a guide ring from the outside.
While being guided by the tapered cap 9 from the inside by the cylindrical guide 14 and the cylindrical guide 13, it falls by its own weight and is wound up by the winding pack 8. The winding pack 8 is rotating counterclockwise at a suitable speed, in which the wire is wound in a circle or a petal.

When the winding pack 8 is full, the winding pack 8
When the rotary solenoid 16 is actuated, the shutter 15 protrudes, the winding to the pack 8 is interrupted, and the wire is temporarily held on the shutter 15. At this time, the ball plunger 11a engages with the concave portion 11b above the shutter 15, and the coupling 10 slips, so that the rotation of the taper cap 9 stops. This prevents the wire 1 held on the shutter 15 from being dragged and tangled by the rotation of the taper cap 9. Shutter
While the wire 1 is being held by 15, the wound-up pack (full-wrapped pack) 8 a is moved by the turret 12 to a position rotated 120 ° counterclockwise, and a new empty pack 8 is supplied to the winding position. You. During the movement, the rotation (rotation) and vibration of the take-up pack are stopped. Full roll pack 8a
Is transferred to the cutting position by the advance of the transfer wire guide arm 18 and is cut by the cutter 17. Since the wire 1 is held by the shutter 15 during the switching of the pack, the high-speed winding can be continued without interrupting the supply of the wire 1.

Thereafter, if the operation of the rotary solenoid 16 is released and the shutter 15 is retracted, the winding of the new pack 8 is continued. Rotation (rotation) and vertical vibration are again applied to the new winding pack 8 whose winding has started. In the embodiment, the rotation directions of the winding pot 3 and the winding pack 8 are counterclockwise, but they may be clockwise.

With the above wire winding device, the solder plating wire could be wound without trouble up to a winding speed of 135 m / min.

The pack moving means such as a turret may be manually operated. However, when the winding speed is increased, it is preferable to detect whether the pack is full or to automatically switch the pack at every predetermined wire length.

〔The invention's effect〕

According to the wire winding device of the present invention, even when the winding speed is 60 m / min or more, the wire can be normally wound without jumping out of the winding pack, and the winding speed can be smoothly increased to a winding speed of approximately 135 m / min. Can be taken.

Further, according to the pack winding device of the present invention including the taper cap, the shutter, the cutter, the pack moving means, and the means for preventing the rotation of the taper cap which rotate independently of the pack, the supply of the wire is not interrupted. The winding can be continued continuously.

The apparatus of the present invention is useful for winding a pack of a solder-plated wire having a flexible surface, but is also useful for winding other wires such as an enameled wire.
