Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a device for inserting an insulating tube into a terminal wire of a molded stator or the like.

Conventionally, as a device for inserting an insulating tube into a terminal wire,
There is a device proposed and disclosed in Japanese Patent Publication No. 55-4600. This device is suitable for wiring work such as control locks.
An insulating tube with incense sticks printed on it is inserted into the wire. Indeed, the insulating tubes used in Mukusoden have relatively large inner diameters and short lengths.
A measure has been taken to feed the insulating tube in row 2 and insert it into the electric wire.

In order to insulate the connection part of the tt1 electric wire, measures such as covering it with a short heat-shrinkable tube with a relatively large inner diameter and fixing it in an island shape have also been taken.

However, conventional insulating tube insertion devices insert short insulating tubes with relatively large inner diameters and ample space between them and electric wires, but when inserting long insulating tubes with insufficient inner diameter into electric wires, In this case, due to the frictional resistance during insertion, the part of the wire where the cheep should be inserted may buckle and bend, and the tube may not be inserted, so conventional devices such as those mentioned above cannot be applied.
When inserting an insulating tube into the terminal wire of the stator of a small model, automation is difficult due to the flexibility of both tubes and the limited inner diameter of the insulating tube, which has traditionally been done manually. The next step is being performed.

The object of the invention is to eliminate the above-mentioned drawbacks of the prior art, and to make it possible to quickly and smoothly insert a terminal wire into a long insulated tube with a small diameter and little margin for the terminal wire without buckling the terminal wire. An object of the present invention is to provide an insulating tube insertion method and an insulating tube insertion device that can automatically selectively insert many kinds of insulating tubes.

The distance 2 causes the wire drawing rollers 18 to approach each other. Furthermore, although the wire retraction roller 1B is separated from the lower tube holder 171L and the wire guide 179 by the release lever 20, it does not approach together with them, but rather approaches after a delay.

Next, the operation of this tube insertion device will be explained.

First, the terminals 4I5 of the stator 4 are preliminarily positioned, the stator 4 is set in a stable state, and the start switch is pressed.The required tube 7 of the tube intex means 8 is positioned.Next, as shown in FIG. The tube holder 16, the lower tube holder 17, and the end *m guide means (wire guide 17 and wire pull-in row 218) are raised and positioned, and the end rt of the nine-chave is clamped. , descends and pulls out the tube to the required length. At this time, the components of the wire guide 17' are brought closer together by the actuation of the opening lever 20, but the wire pull-in rows 218 are not yet brought closer to each other, in this state. The upper part of the tube 7 is held down with a tube holding tool 9, and the tube 7 is cut to a required length with a cutter 10. This state is shown in FIG.

On the other hand, below, the terminal line positioning chuck 24 moves forward to a predetermined position, slides over the South America WA5 while being held in place by the terminal line st springer, and rises. Stretch the lAs vertically, leave a predetermined length smaller than the tip of the terminal wire, stop at the hole position, and wait.

The tip of the terminal I15 is now positioned. The specified dimension from the tip is the shortest possible length for positioning the tip and preventing buckling of the tip. If there is a possibility that the tip of the terminal @S is bent, the positioning chuck 24 should be set at a degree S that is approximately equal to or slightly longer than the vertical length of the wire guide.
Raise it to the tip of + and then lower it by a predetermined distance.

Next, the tube clamping means 116, 17 and the terminal line guide means 17', 18 are lowered. As shown in Figure 4, terminal I
The tip of the wire guide 1r is guided by the horn-shaped peep of the wire guide 17' and securely enters the tube 7. At this time, the lower end of the wire guide 1r approaches the positioning chuck 24. Then, the first positioning chuck 24 releases the grip on the terminal I15, retreats, and descends. At the same time, the wire lead-in rows I) 18 approach each other and sandwich the terminal-5, causing the terminal @
The circumferential speed of the wire drawing roller 18 through which the wire 5 is fed is set to be equal to or higher than the descending speed of the tube 7. This state mt is shown in FIG. This prevents buckling of the terminal and allows high-speed tube insertion! - The upper and lower tip holders 16 and 17, the wire guide 17' and the wire retraction roller 18 are lowered simultaneously, and the release lever 20 is activated before the lower part of the wire guide 17'' contacts the stator 4. The lower tube holder 17 and the wire guide 17 are in contact with the lever driving cam 23 and are integrated.

This completes the tube insertion. During this time, the tube indexing means 8 moves the tip 7° of the tube to be inserted next.
Insert it and position it in the correct position.

When the tube has been inserted, the upper tube holder 16 releases its grip and rises. The lower tube holder 17, the wire guide 17', and the +teer pull-in roller 18 move up to the position of holding the next tube. When the tube clamping means or the like is raised, the lumber indexing hand R2 is actuated to index the next terminal into a predetermined position.

In this way, insert the tube for the next terminal wire.

When the tubes are inserted into the required number of terminal wires of the stator 40, the device stops.
