Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is for inserting filamentous materials such as electric wires, wires, or threads used in the electronics industry, textile industry, etc. into relatively small diameter through holes. The present invention relates to a filament insertion device.

<Prior Art> Conventionally, a device for inserting a filamentous object such as a wire into a relatively small-diameter through hole has been used by rotating a pair of rollers that sandwich the filamentous object from both sides, or by By moving a pair of fingers that grip the object from both sides, the filament is sent out while being positioned with respect to the through hole, and the tip of the filament inserted through the through hole is pulled out by another roller or finger. What has been done is generally known.

<Problems to be Solved by the Invention> When such a device is used, the filament is positioned and delivered with high precision, but due to differences in the surface roughness of the through-holes and processing variations during the formation of the through-holes, Due to minute positional deviations in the through-hole, when the filament is inserted into the through-hole, the axis of the filament and the hole center of the through-hole may not align accurately. In such a case, the tip of the filament comes into contact with the edge of the through hole or the inner wall surface of the through hole, and the frictional force generated at that time makes it impossible to insert the filament smoothly into the through hole, and the filament There is a problem in that it is not possible to insert a predetermined length of the object into the through hole.

The present invention has been made in view of the above-mentioned technical problems, and it is possible to always insert a filament into a through-hole reliably, regardless of differences in surface roughness of the through-hole or minute positional deviations of the through-hole. The object of the present invention is to provide a device for inserting a filament into a through-hole, which can quantitatively control the insertion length of the filament.

Means for Solving the Problems> In order to solve the above problems, the filamentous object insertion device of the present invention includes the following features:
The roller includes at least a pair of rollers, a roller drive device for driving the rollers, and a filament delivery guide body disposed before and after the rollers, and the rollers clamp the filament and rotate the filament by rotationally driving the filament. In addition to sending out striae,
The filament delivery guide body is provided with a guide hole, and the filament, which is slidably inserted into the guide hole, is guided by an air flow, and the air flow is directed from the delivery port of the filament. I try to spit it out.

Action> The filamentous material delivery guide body drive device opens the filamentous material delivery guide body, and the filamentous material is placed so as to face the introduction part, the guide part, and the diff user part formed on the filamentous material delivery guide body. After being placed, the filamentous material delivery guide body is closed and polymerized by the filamentous material delivery guide body driving device, the filamentous material is held between the rollers, and the introduction hole, guide hole, and diffuser of the filamentous material delivery guide body are closed and polymerized. It is inserted and held inside.

Next, after the filament outlet, that is, the tip of the filament, is positioned to face the through hole into which the filament is to be inserted,
Air is sent to the filament delivery guide body, and the rollers are driven by a roller drive device to insert the filament into the through hole.

At this time, the air flow sent to the filament delivery guide provided on the downstream side (through-hole side) of the roller is discharged almost uniformly from around the filament, so the axis of the filament is Even if the filament does not exactly align with the hole center of the through hole, the direction is corrected so that the tip of the filament faces the through hole along the flow direction of the airflow, and the filament is inserted securely into the through hole. It will be introduced smoothly. Furthermore, since the filament is transferred by at least one pair of rollers that sandwich the filament, the filament can be quantitatively transferred by controlling a roller drive device that rotationally drives the rollers. At this time, the filamentous material is reliably and smoothly introduced between the rollers by aligning the air flow direction with the filamentous material transport direction by the filamentary material delivery guide provided on the front side of the rollers. - <Examples> Examples of the present invention will be described below with reference to the drawings. 1 to 7 each show an embodiment of the linear object insertion device of the present invention, FIG. 1 is a sectional view taken along line A-A in FIG. 5, which will be described later, and FIGS. 2 and 3 are FIGS. 4 and 5 are front views of the filament delivery guide body in an open state and a closed state, respectively, and FIGS. 6 and 7 are B of FIG. 4, respectively. -B sectional view and C

On the opposing surfaces of each of the filamentous material delivery guide bodies 5.6 and 7.8, there is provided a line that forms a hole when the filamentous material delivery guide bodies 5.6 and 7.8 are closed and in a superposed state. Article 9
introduction parts 5a, 6a, 7a, 8a, and guide parts 5b,
6b, 7b, 8b, and the differential user section 5c.

6c, 7c, and 8c are connected to each other, and as shown in FIG. Hole 10.
11, guide hole 12.13 and differential user 14.1
5 respectively. Reference numeral 31 is a delivery port for the filament 9 and the tip of the diffuser 14 .

In addition, each filament delivery guide body 5.6.7.8 has air supply holes 5e, 6e that communicate from the upper air inlets 5d, 6d, 7d, 8d to the diff user parts 5c, 6c, 7c, 8c, respectively. , 7e, 8e are perforated, and the air inlets 5d, 6d, 7d, 8d are connected to an air supply source (
Air is supplied from (not shown).

As shown in FIGS. 1.6 and 7, rollers 16.17 for transporting the filament 9 are provided between the filament delivery guide bodies 5.6 and 7.8. The roller 16 is rotatably supported between roller support members 16a and 16b, and one ends of these roller support members 16a and 16b are attached to the support member 2. Further, the roller 17 is
It is rotatably supported between roller support members 17 and 17b, and one end of these roller support members 17a and 17b is attached to support member 3. These rollers 16.17 are positioned so as to sandwich the filament 9 from both sides when the support member 2.3 approaches in the closing direction. A roller drive device 18 that rotationally drives the roller 17 is provided on the roller support member 17a.

Next, the operation of this embodiment will be explained.

As shown in FIG. 4, when each drive shaft 4 is protruded by the opening/closing chuck mechanism l, the support members 2.3 move in the direction of separation, and the filament delivery guide bodies 5.6 and 7.
8 Furthermore, both rollers 16 and 17 are opened. In this state, the filamentous material 9 is moved from below to the filamentous material delivery guide bodies 5 and 6.
7 and 8, and further between rollers 16 and 17 by an actuator (not shown), and each introducing portion 5a, 5a.

7a, 8a, guide portion 5b, 6b, 7b, 8b,
7' Ear is kept stationary at a height position facing the s-ear portions 5c, 6c, 7c, 8c and the rollers 16 and 17.

Thereafter, the opening/closing chuck mechanism l is driven to suck each drive shaft 4, and the filament delivery guide bodies 5.6 and 7.8 insert the filament 9 as shown in FIGS. 1 and 5. The roller 16 is polymerized while the roller 16
．． The filament 9 is held between the grips 17. At this time, the filament 9 includes the differential users 14 and 15 formed by the differential user parts 5c, 6c, 7c, and 8c, the guide holes 12 and 13 formed by the guide parts 5b, 6b, 7b, and 8b, and the introduction part 5as. 6a, 7a,
It is held inserted into the introduction holes 1o and 11 formed by 8a, respectively.

Next, the filament 9 is cut by a cutting mechanism (not shown) so that the protruding length of the tip of the filament 9 from the outlet of the diff user 14, which is the delivery port 31 of the filament 9, becomes a predetermined length. disconnected. Thereafter, the filament insertion device is positioned so that the tip of the filament 9 faces the through hole 19 into which the tip is to be inserted.

In this state, air is supplied from the air supply source into the differential users 14 and 15 through the air supply holes 5e, 6e, 7e, and 8e, and the roller drive device 18 By rotationally driving the roller 17 in the direction of the arrow E, the roller 16 is also rotationally driven in the direction of the arrow F, and the filament 9 is transferred in the direction of the arrow G and sent out from the diff user 14, 15. At this time, the low-speed, high-pressure air flow supplied through the air supply holes 5e, 6e, 7e, and 8e is caused by the diff user 14.15 whose diameter tapers toward the outlet.
Converts into high-speed, low-pressure airflow. At this time, the air flowing into the differential user 14.15 is transferred to the guide hole 12.13.
Since the diameter of the filament 9 is slightly larger than the diameter of the filament 9, there is almost no gap between the guide hole 12.13 and the filament 9, which prevents the flow from flowing backward from the guide hole 12.13. In the diffuser 14 , 15 , it flows almost uniformly around the filament 9 and is discharged from the outlet 31 .

Therefore, in the filamentous material delivery guide body 5.6, the high-speed airflow uniformly discharged from the periphery of the filamentous material 9 flows through the through hole 19.
Even if there is a difference in the surface roughness of the through holes, or even if for some reason the axis of the filament 9 and the flower core of the through hole 19 do not match exactly, the line The direction of the tip of the strip 9 is corrected so that it faces the through hole 19 along the flow of the airflow, and is introduced into the through hole 19 reliably and smoothly.

Further, since the transfer amount of the filament 9 is determined by the rotation of the rollers 16 and 17, the transfer amount of the filament 9 can be arbitrarily set by the drive amount of the roller drive device 18 to transfer the filament 9. can be controlled quantitatively.

Note that the present invention is not limited to the examples described and illustrated above, and may include various modifications without departing from the scope of the claims. For example, a case has been described in which the filament delivery guide bodies 5.6 and 7.8 are provided with the differential users 14 and 15, respectively. A low-pressure, high-speed air flow may be supplied from the filamentous material delivery guide body 5.6.7.8. You may also provide one. Further, although a pair of rollers 16 and 17 are provided, two or more pairs of rollers may be provided.

<Effects of the Invention> As explained above, according to the linear object insertion device of the present invention,
A filamentous material delivery guide body that guides the transportation of the filamentous material by airflow and discharges the airflow from the delivery port of the filamentous material, and at least one pair that transports the filamentous material by holding and rotating the filamentous material. Since it is equipped with a roller and a linear material delivery guide body that smoothly supplies the linear material to this roller,
The filament can always be reliably and smoothly inserted into the through hole without being affected by differences in surface roughness or minute positional deviations of the through hole. Moreover, the filamentous material can be reliably and smoothly transferred to the rollers by the filamentous material delivery guide body that always feeds the filamentous material to the center of the roller.
