Description

[Detailed Description of the Invention] The present invention relates to a parallel shaft continuous wire winding machine.

2. Description of the Related Art A conventional parallel shaft continuous wire winding machine for winding a wire such as a core wire for a communication cable made of a solid annealed copper wire coated with plastic on a reel is shown in FIG. 1, for example.

The wire 1 passes through an inlet guide sheave 2, enters a wire storage section 3 for controlling tension, is sent from an outlet guide sheave 4 to a guide sheave 5, and then passes between a pair of sheaves 6a and 6b. Take-up reel 7
(or the take-up reel 8 arranged parallel to this). The pair sheaves 6a and 6b are capable of reciprocating in the direction of the rotation axis of the take-up reels 7 and 8,
The length of the winding portions of the winding reels 7 and 8 (the distance between the flanges of the winding reels 7 and 8) is continuously reciprocated in synchronization with the rotational speed of the winding reels 7 and 8. The guide sheave 5 is arranged so that it moves following the reciprocating motion of the pair sheaves 6a, 6b.
b is supported on a support member (not shown), and the filament 1 is arranged so as to enter between the pair rolls 6a, 6b, and the pair rolls 6a,
It is supported so as to be able to swing around a vertical axis 9 (coinciding with the center line of the vertically descending filament 1) passing through the middle of 6b as a rotation axis. Similarly, the exit guide sheave 4 is also swingable about a vertical shaft 10 passing through the entry position of the filament 1 as a fulcrum. With this configuration, the filament 1 is wound up as shown in FIGS. 2-4. FIG. 2 shows a state in which the filament 1 is wound on the take-up reel 7 closest to the flange 7a. From this state, the pair sheaves 6a, 6b and the guide sheave 5 move toward the flange 7b on the opposite side. FIG. 3 shows a state in which the paired sheaves 6a, 6b and the guide sheave 5 have reached approximately the center of the take-up reel 7. As the paired sheaves 6a and 6b move, the exit guide sheave 4 and the guide sheave 5
The angle θ that the filament 1 makes with its initial position increases, but since the outlet guide sheave 4 and the guide sheave 5 are both swingable about the vertical axes 10 and 9, the filament 1, the outlet guide sheave 4 and the guide sheave 5 swing by an angle θ to allow the filament 1 to flow smoothly. In this way, when the pair of sheaves 6a and 6b reach the flange 7b as shown in FIG. 4, they move in the opposite direction and return to the state shown in FIG. 2 again. By repeating this, the filament 1 is wound onto the take-up reel 7.

However, since the conventional winding machine had the above-mentioned configuration, there was a problem in that when the paired sheaves 6a and 6b changed the moving direction, extra tension was applied to the filament 1, reducing its elongation rate. .
That is, the pair sheave 6a, 6b is, for example, the fourth
In the state shown in the figure, the traveling direction is changed to the exact opposite direction, but the swinging direction of the guide sheave 5 and the outlet guide sheave 4 must also be changed at the same time. However, a large inertial force acts on the swingably supported guide sheave 5 and the outlet guide sheave 4 at the time of direction change, and at the moment of direction change, the guide sheave 5
As shown in FIG. 5, the exit guide sheave 4 swings beyond its original stop position, and an unexpected force is applied to the filament 1.

Furthermore, switching from one fully wound take-up reel 7 or 8 to the other empty take-up reel 8 or 7 is performed when the filament 1 comes to the furthest flange side of the take-up reel. There was also a problem that if the guide sheave 5 vibrated, this switching could not be performed smoothly.

The object of the present invention is to obtain a continuous wire winding machine that solves the conventional problems as described above.

Hereinafter, the present invention will be described with reference to FIGS. 6 to 9 of the accompanying drawings showing embodiments thereof.

The filament 11 enters the wire storage section 13 through an inlet guide sheave 12, passes through a vertical guide sheave 14 provided at the outlet of the wire storage section 13, and a horizontal first guide sheave 15 substantially perpendicular thereto. Furthermore, it passes through a second guide sheave 16 that is parallel to and on the same plane as the first guide sheave 15, makes a U-turn, is sent to a pair of sheaves 17a and 17b that have rotational axes perpendicular to the second guide sheave 16, and then Take-up reel 18 (or take-up reel 1 arranged parallel to this)
9). The pair sheave 17a, 17b and the second sheave 16 are supported on the same support member (not shown), and the length of the take-up portion (take-up reel) is It is possible to reciprocate between the flanges (distance between flanges 18 and 19).

By this wire winding machine, the wire 11 is
It is wound up as shown in the figure. Figure 7 shows
The filament 11 is located at the most flange 18a of the take-up reel 18.
Shows it being rolled up on the side. From this state,
The pair sheaves 17a, 17b and the second guide sheave 16 are connected to the other flange 18 of the take-up reel 18.
It moves in the direction b, and when it reaches the position closest to the flange 18b shown in FIG. 8, it changes direction and now moves toward the flange 18a, returning to the state shown in FIG. 7 again. By repeating this, the filament 11 is wound onto the take-up reel 18.
When the take-up reel 18 is fully wound, the winding is then carried out on the other take-up reel 19 in the same manner. When the paired sheaves 17a and 17b change direction, the first and second guide sheaves 15 and 16 do not assist, so that no abnormal force is applied to the filament 11 due to inertia, and the filament 11 is moved steadily and smoothly. 11 is being wound up.

In the above embodiment, the first and second guide sheaves 15 and 16 are arranged horizontally, but the arrangement is not limited to this, and the paired sheaves 17a,
17b reciprocating direction (i.e. pair sheave 17
The object of the present invention can be achieved by arranging the first and second guide sheaves so that the rotation axis of the guide sheave is orthogonal to (or more precisely, spatially orthogonal to) the rotation axis of . This means that the inclined first and second guide sheaves 15' and 1
This will become clearer with reference to FIG. 9, which shows 6'.

As explained above, according to the present invention, the first sheave having the rotation axis orthogonal to the rotation axis of the pair sheave
A guide sheave is provided at the wire storage section outlet, and a second guide sheave having a rotation axis parallel to the first guide sheave and located on the same plane as the first guide sheave is configured to reciprocate together with the pair sheave. A first guide sheave,
Since the second guide sheave, pair sheave, and take-up reel are passed in this order, when the pair sheave changes direction, the guide sheave does not swing unnecessarily due to inertia, and harmful external forces are not applied to the wire. Therefore, stable winding operation is possible at all times, and the elongation rate of the filament is not reduced.
