Abstract

PURPOSE:To insert a linear material reliably into a through-hole by guiding carriage of a linear material inserted into a guide hole slidably through air-flow and providing a linear material guide body for delivering the air flow through feed-out port of the linear material. CONSTITUTION:A linear material 7 is guided by linear material guides 5, 6 and held by a pair of rollers 11, 12. Then the tip of the linear material 7 is positioned to face with a through-hole 14, and air-flow delivered through a feed-out port flows into the through-hole 14. Since the air flow is delivered uniformly from the circumference of the linear material 7, the tip section of the linear material 7 is directed to face with the through-hole 14 along the direction of air flow even when the axis of the linear material 7 does not match accurately with the axis of the through-hole 14, and the linear material 7 is led into the through-hole 14 reliably and smoothly. Since movement of the linear material 7 is controlled through the pair of rollers 11, 12, the linear material 7 is carried quantitatively through the roller driver.

Description

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

<Prior Art> Conventionally, as a device for inserting a filamentous object such as a wire into a relatively small-diameter through hole, a device that rotates a pair of rollers holding the wire from both sides, or a device that grips the wire from both sides has been used. It is generally known that the wire is sent out while being positioned in the through hole by the movement of a pair of fingers, and the tip of the wire inserted through the through hole is pulled out by another roller or finger.

<Problems to be Solved by the Invention> However, although the wire is positioned with high precision with respect to the through-hole and sent out, there may be small problems due to differences in the surface roughness of the through-hole or variations in the formation of the through-hole. Due to the misalignment, the axis of the wire and the core of the through-hole may not accurately match when the wire is inserted into the through-hole. In such a case, the tip of the wire comes into contact with the edge or inner wall of the through hole, and the frictional force generated at that time makes it impossible to insert the wire smoothly into the through hole, and the wire cannot penetrate the specified length. There is a problem that it cannot be inserted through the hole.

<Purpose of the Invention> The present invention has been made in view of such conventional technical problems, and it is possible to always insert a filament object into a through hole reliably regardless of minute positional deviation of the through hole, and also to It is an object of the present invention 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> The present invention has the following technical means for solving the problems described above. That is, in a device for inserting a small-diameter filamentous object such as a wire or electric wire into a small-diameter through hole, the airflow guides the transfer of the filamentous object slidably inserted into the guide hole, and the airflow is A filamentous material delivery guide body is provided for discharging the filamentous material from a delivery port, and the filamentous material is held at a position in front of the filamentous material delivery guide body in the direction of transport of the filamentous material, and the filamentous material is delivered by rotational drive. It is characterized by the provision of a pair of rollers that are fed out from the outlet and a roller drive device that controls the rotation of the rollers.

Effect> When the outlet of the filament, that is, the tip of the filament is positioned to face the through hole into which the filament is to be inserted, the airflow discharged from the outlet flows into the through hole. At this time,
Airflow is discharged almost uniformly from around the striated object, so
Even if the axis of the filament does not exactly match the center of the through-hole, the tip of the filament is oriented so that it faces the through-hole along the air flow direction, and the penetrating It can be introduced into the hole reliably and smoothly. Furthermore, since the transportation of the filament is controlled by at least a pair of rollers that sandwich the filament, the filament can be quantitatively transferred by a roller drive device that rotationally drives the rollers.

<Examples> Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

1 to 7 each show an apparatus for inserting a filament into a through hole according to an embodiment of the present invention, and FIG. 1 is a cutaway plan view taken along line A-A in FIG. 5, which will be described later. , FIGS. 2 and 3 are perspective views seen from the front and rear, respectively, FIGS. 4 and 5 are front views in the open and closed states, respectively, and FIGS. 6 and 7 are respectively the same as in FIG. 4. A BB cross-sectional view and a CC line cross-sectional view are shown, respectively.

In these figures, flat support members 2.3 are movably provided on both sides of the air chuck mechanism 1 by four drive shafts 4 that are driven to attract and project. A pair of block-shaped filament delivery guide bodies 5 and 6 are fixed to opposing lower surfaces of both support members 2.3, respectively, and as shown in FIGS. 6 and 7, Both filament delivery guide bodies 5 and 6 are driven to open and close by the protrusion and suction drive of each drive shaft 4.

On the opposing surfaces of each of the filamentous material delivery guide bodies 5 and 6, there is an introduction portion 5a for the filamentous material 7 which becomes flower-shaped when both the filamentous material delivery guide bodies 5 and 6 are closed and in a superposed state. ,6a

Air supply holes 5e and 6e communicating with the differential user parts 5c and 6c from 6d are bored, and air inlet ports 5d and 6d are formed.
is supplied with air from an air supply source (not shown).

The rollers 1) and 12 for feeding the filamentous material are placed at the front stage position in the feeding direction of the filamentous material 7 with respect to the filamentous material feeding guide body 5.6 in each support member 2, 3, and both support members 2 and 3 are closed. The filament 7 is positioned and rotatably mounted so as to sandwich the filament 7 from both sides when approached in the direction. A roller drive device 13 that controls the rotation of the roller 12 is connected to one of the rollers 12 .

Next, the operation of the above embodiment will be explained.

As shown in FIG. 4, each drive shaft 4 of the air chuck mechanism 1 is discharged to move both support members 2.3 in the direction of separation, and both filament delivery guide bodies 5, 6 and a pair of When the rollers 1) and 12 are in an open state, the filament 7 is loosely inserted from below between the filament delivery guide bodies 5 and 6 and the pair of rollers 1) and 12 by an actuator (not shown), and Each differential user part 5C16C% guide part 5b, 6b, introduction part 5a, 6a and roller 1)
．． It is stopped at a height position opposite to 12.

After that, the air check mechanism 1 is driven to suck each drive shaft 4, and as shown in FIGS. A pair of rollers 1). 12
The filament 7 is held between the two. At this time, the filament 7 includes a differential user 10 formed by both differential user portions 5C16c, a guide hole 9 formed by both guide portions 5b and 6b, and both warm-in portions 5.
They are held inserted into the introduction holes 8 by a and 6a, respectively.

Then, each roller 1)゜12
is rotated in the direction opposite to the arrow in FIG. 1, the filament 7 is moved in the direction opposite to the arrow, and the protrusion length of the tip of the filament 7 from the outlet of the differential user 10 is set to a predetermined value. . Next, the through hole 14 into which the filament 7 is to be inserted is inserted into the tip.
After the air supply holes 5e and 6 are positioned so as to face each other, the air supply holes 5e and 6 are connected from the air supply source as shown by the one-dot chain arrow in FIG.
Air is supplied into the differential user 10 through e, and the filament 7 is transferred in the direction of the arrow by the rotational drive of the rollers 1) and 12 in the direction of the arrow.
It is sent out from. At this time, the low-speed, high-pressure air flow supplied through the air supply holes 5e, 6e is converted into a high-speed, low-pressure flow by the diffuser 10, which has a tapered small diameter toward the outlet, and this high-speed air The flow enters through hole 14 . At this time, the air flowing into the diff user 10 is prevented from flowing backward by the guide hole 9, which is formed to have a diameter slightly larger than the diameter of the filament 7, so that there is almost no gap between the air and the filament 7. Default user 10
It flows almost uniformly around the filament 7 and is discharged under pressure from the outlet. Therefore, a high-speed airflow uniformly discharged from around the filament 7 flows into the through hole 14, so that for some reason the axis of the filament 7 and the flower core of the through hole 14 may not exactly match. If not, the direction of the tip of the filament 7 is corrected so that it faces the through hole 14 along the flow of the airflow, and the filament 7 is reliably and smoothly introduced into the through hole 14. Further, since the amount of transfer of the filament 7 is determined by the rotation of the pair of rollers 1) 12, the amount of transfer of the filament 7 can be arbitrarily set by the drive amount of the roller drive device 13, transfer can be quantitatively controlled.

It should be noted that the present invention is not limited to the above description and illustrated examples, and may include various modifications without departing from the scope of the claims. For example, although the case has been described in which the diff user 10 is provided in the filament delivery guide bodies 5 and 6, it may be simply cylindrical and may be configured to supply a low-pressure, high-speed air flow from an air supply source. 4 may have two each on the left and right.

<Effects of the Invention> As detailed above, according to the device for inserting a filament into a through hole of the present invention, the transportation of the filament is guided by the airflow, and the airflow is discharged from the outlet of the filament. Since the configuration includes a filamentous material delivery guide body, at least a pair of rollers that transfer the filamentous material by holding and rotating the filamentous material, and a drive device for this roller, the air flowing into the through hole is Since the direction of the tip of the filament can be corrected by the flow, the filament can be inserted into the through-hole reliably and smoothly at all times without being affected by differences in surface roughness or minute positional deviations of the through-hole. can. Further, the transportation of the filament can be quantitatively controlled by the rollers and the roller drive device.
