[0008]

However, according to the wire guide roller of the conventional solder plating apparatus, the wire group is provided with a roll group consisting of a pressing roll, a tension roll, a tansieve, etc. Wears on the surface in contact with the bearing, or the bearing becomes abnormal. For this reason, usually, the rolls are exchanged regularly (all the roll groups are exchanged at the same time) twice a year. However, this replacement work requires 2 hours / time for each plating tank, which is a disadvantage that a considerable amount of time must be spent.

In addition, when the roll group is replaced during operation (during operation), the line must be stopped and replaced.
In consideration of a plurality of plating tanks and a stop time of the solder plating work, it is inevitable that productivity is lowered due to the time required for replacement. Therefore, it is an object of the present invention to provide a wire guide roller unit that can switch rolls without stopping the processing applied to the wire.

[0010]

In order to achieve the above-mentioned object, according to the present invention, one or a plurality of wires are sequentially passed between a plurality of rollers, and a predetermined treatment is applied to the wires in the process. In the wire guide roller unit to be applied, a roll holder provided so as to be rotatable on a shaft of a fixed system, and a plurality of rolls arranged at equal intervals so as to be rotatable on the same circumferential line on the side surface of the roll holder. It has a configuration with.

According to this structure, the roll that is worn out is retracted from the pass line only by rotating the roll holder by a predetermined angle, and a new roll without wear appears on the pass line. Therefore, the rolls can be exchanged without attaching or detaching the rolls. As a result, it is not necessary to frequently attach and detach the rolls, and it is possible to improve the operating rate and eventually the productivity.

[0012] The roll holder may have a structure in which the roll holder is rotated by a predetermined angle according to the number of worn rolls among the plurality of rolls, and is fixed after the rotation. According to this configuration, by setting and rotating the rotation angle of the roll holder according to the number of rolls that have been in contact with the wire, that is, the number of worn rolls, a plurality of new rolls that have not been worn contact the wire. Come to do. This allows
It is not necessary to replace the unit until all the rolls mounted on the roll holder are worn, and the number of roll replacements can be reduced.

Further, the plurality of rolls may have a screwing structure or a pressure contact holding structure with respect to the roll holder. According to this configuration, for the roll holder,
To attach and detach a plurality of rolls, a screwing means using a nut or a means for holding the roll base portion in a pressurized state by an elastic member such as a leaf spring can be used, and the rolls can be attached and detached in the shortest time.

Things. Therefore, the roll unit shown in FIG.
When applied to the configuration of FIG. 1, 16 roll units
You will need it.

On one surface of the disk-shaped roll holder 24, a plurality of rolls are arranged at predetermined angles (here, the rolls 25a,
25b, 25c, 25d, 25e, 25f, 25g, 2
5h, 25i, 25j, 25k, 25l, all 12 are 3
The collars 26 are attached to each other at an interval of 0 ° (the ends of which are externally threaded or integrally formed with an insertion shaft). Further, a cylindrical flange 27 is provided at the center of rotation on the back surface of the roll holder 24. The flange 27 includes collars 3 _{-1 to} 3 _-n , 4 _-1 to 4 _-n shown in FIG.
It is fixed to a shaft (not shown) via 13 _{-1 to} 13 _-n , 14 _{-1 to} 14 _{-n and the} like.

Each of the rolls 25a to 25l can be mounted by using a screwing system or a one-touch fitting system. As shown in FIG. 3, in the screwing method, the collar 26 is screwed into the male screw portion 28, and this is held by the roll holder 24.
It is configured such that it is passed through the through hole provided in the above and is tightened and fixed by the nut 29 on the back surface. In addition, the one-touch fitting method is shown in FIG.
As shown in, the collar 26 is pressed onto the insertion rod 30. On the other hand, the roll holder 24 is provided with a through hole 31, and a plurality of leaf springs 32 are interposed in the through hole 31. By inserting the insertion rod 30 of the roll 25 into the through hole 31 in this state, the insertion rod 30 is pressed against the inner surface of the leaf spring 32,
It will not come out under normal use.

In the above structure, the wire 23 is stretched in the direction of the arrow by the rolls 25a, 25b and 25l and the restraining rolls 8 and 9 as shown in FIG. As described above, the plurality of planetary rolls (here, three rolls 25a, 25b, and 25l) in the pass line of the wire 23 are worn by the contact with the wire 23 after being used for a certain period of time. If it is determined that the roll holder should be replaced, the roll holder 24 is rotated 90 ° (automatically or manually).
Let it. Then, the unused rolls 25c, 25d, 25
Three of e come to come to the pass line of the wire 23.
As a result, the rolls can be exchanged without stopping the passage of the wires 23 (that is, without stopping the solder plating) and without attaching or detaching the rolls. Further, since it is only necessary to rotate the roll unit, the surrounding area is not soiled.

Here, an example is shown in which the tension rolls 7 _{-1 to} 7 _-n are used, but the number of rolls used at a time differs depending on the place to be used and the type of roll, and the rotation angle is 180 °, 60 ° or It will be different, such as 30 °. When all the planetary rolls on the roll holder 24 are in a worn state, the line is stopped or replacement work is carried out when not in operation. First, worn roll 2
All of 5a to 25l may be removed and replaced with new rolls 25a to 25l. Alternatively, the roll holder 24 may be removed from the shaft and replaced with a new roll unit. For the removed roll unit, the worn rolls 25a to 25l are removed and replaced with new rolls 25a to 25l to prepare for the next replacement. When the rolls 25a to 25l have the configuration shown in FIG. 3, the nut 29 can be loosened and removed, and can be easily replaced with a new planetary roll. Also,
In the case of the configuration of FIG. 4, it is sufficient to pull out the rolls 25a to 25l with a tool or a hand, and new rolls 25a to 25l.
The mounting of l is completed by simply pushing it into the through hole 31.

As described above, according to the present invention, when the roll is worn, the entire unit is rotated so that the new roll 25 comes to the pass line of the wire 23, and the roll is replaced as in the conventional case. Can be in the same state as. By reducing the number of roll exchanges, the operating rate of the line can be improved and productivity can be increased. Also, roll replacement (roll unit replacement) can be performed systematically.

In the above construction, the roll 25
However, the present invention is not limited to 12 and can be arbitrary. However, considering that the whole is rotated during operation, if the number of wires decreases, the wire tension will change significantly, so
Not preferred. Furthermore, as the rolls 25a to 25l, commercially available products that are easily available can be used. In this case, from the design stage, the colors 3 _{-1 to} 3 _-n , 4 _-1 to 4 _-n , 13 _-1 to 1
It is necessary to consider the intervals of 3 _-n and 14 _{-1 to} 14 _-n .

When the rolls 25a to 25l are made of a metal having a relatively low abrasion resistance, the surface contacting the wire can be treated to have abrasion resistance. For example,
A metal film such as titanium nitride (TiN) or tungsten carbide (WC) having high hardness may be used to form a metal film on the roll surface by a vapor deposition technique.

[0022]

As described above, according to the present invention, a plurality of rolls are mounted on the roll holder so that they are arranged at equal intervals on the same circumferential line and the pass lines match the wires. The number of roll replacements is reduced, the line operating rate is improved, and productivity can be increased. Also, it becomes possible to plan the roll replacement timing.
