Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for arranging a plurality of electric wire pieces having a substantially constant length or a variable length within a fixed range in parallel and fixing the parallel condition with an adhesive tape.

[0002]

2. Description of the Related Art A large number of wire pieces are attached, for example, after crimping a conductive terminal to a bare wire end, or following the crimping, a wire identification piece is attached near the conductive terminal or in a central portion between both ends of the wire. After that, it is often delivered to the wiring work site or supplied to the electrical equipment manufacturer. However, hitherto, there has been nothing to be seen as an appropriate automatic device for efficiently bundling and packing such a large number of electric wire pieces.

Therefore, such work is often dependent on human power, and it is common to pack and pack an extremely large number of wire pieces for each wire type or conductive terminal type depending on the attention of the operator. Therefore, not only was the work inefficient, but there were many unfavorable problems such as incorrect counting, mixing of different types of electric wires, and confusion at the work site.

[0004]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a fixed length or a fixed range which is continuously fed from a terminal crimping machine, an electric wire identification piece attaching machine or another electric wire piece processing apparatus. The above problems can be solved at once by providing a device that is suitable for continuously connecting electric wire pieces of the same length with adhesive tape and in a state that does not hinder the handling in the final application. Especially.

[0005]

The structure of the present invention for attaining this object will first be briefly described with reference to the reference numerals in FIGS. The aligning and pasting device is a pair of left and right arranged at predetermined intervals which are driven so as to travel from the entrance (A) to the exit (B) of the conveyor (C) in the upper path (10a).
On the outer surfaces of the endless belts (10) , (10) , feed claws (11) in a direction intersecting with the line connecting the inlet and the outlet are projected at equal intervals, and at positions corresponding to the left and right sides . Mutual
There is no a line to, these left and right pair of endless belts (10), in the vicinity below the adhesive tape facing upward adhesive surface from below (21) the inlet of (A) between (10) An upper adhesive tape (22), which is supplied from the first feeder (31) so as to be parallel to the upper path of the belt and has an adhesive surface facing downward from above the endless belt (10), is located near the inlet in the upper path (10a). ) Is supplied from the second feeder (32) so as to be parallel to the above), and the upper side of the electric wire pieces (D), (D), ... Which are aligned in parallel by the feed claw (11) of the upper path (10a). Adhesive tapes (21) and (22) are sequentially attached to the peripheral surface portion and the lower peripheral surface portion, and both tapes in a portion between adjacent electric wire pieces are attached to the pair of left and right endless belts (10 ) before reaching the outlet (B). ),
A pressing means (40) having a pressing member that is urged in a direction toward each other so as to bond the adhesive surfaces to each other by sandwiching them from above and below is arranged between (10) .

[0006] As a typical example, the first and second feeders rotatably hold the core of the adhesive tape wound around a short cylindrical core or the reel hub around which the tape is wound. It is a fixed axis. It is desirable that the tape is a single-sided adhesive tape having a pressure-sensitive adhesive applied on only one side.

As a mechanism for feeding the endless belt along the upper path from the entrance to the exit and returning it along the lower path from the exit to the entrance, a positive drive roller is arranged on the exit side and It is preferable to use an endless track type in which an idle roller is arranged. If necessary, a tension adjusting roller can be provided in the lower path.

If the endless belts are arranged on both the left and right sides of the moving path of both adhesive tapes that are vertically aligned and run opposite to each other, the wire pieces should be kept in a parallel posture until reaching the conveyor outlet. Is convenient. However, when the pressing means has a positive feeding function, or when the covered electric wire has an appropriate diameter and is sufficiently rigid,
In such cases, the endless belt may be arranged on only one side.

[0009]

In the apparatus of the present invention, the electric wire pieces supplied to the conveyor inlet from the automatic continuous crimping machine, for example, at regular time intervals are first the lower adhesive tape (or the upper adhesive tape, the following "0022" item). (See above) and then the upper adhesive tape (or the lower adhesive tape, same as above), it is sandwiched between the preceding electric wire pieces with an interval equal to the pitch of the feed claw. In this way, the electric wire piece in the temporarily adhered state is firmly adhered to both tapes by the pressing means at a point where the electric wire piece is further advanced by a slight distance.

Since the pressing means urges, for example, free rotating rollers as upper and lower pressing members in the approaching direction, the portions of both tapes located between the preceding electric wire piece and the succeeding electric wire piece are Adhesive coated surfaces are "directly"
Moreover, they are firmly joined, and a large number of electric wire pieces and both tapes are integrated. Therefore, the electric wire piece propulsion force by the feed claw of the endless belt also acts on both adhesive tapes through each electric wire piece,
Also, the withdrawal of the adhesive tape from the second feeder is autonomously performed following the operation of the conveyor.

As is clear from the above, when this device is installed in a one-to-one relationship by being connected to the outlet of the automatic continuous crimping machine or the automatic identification piece mounting machine, the conveyor is operated at a speed synchronized with these machines. The belt is driven. However, it goes without saying that it is not necessarily connected to a crimping machine or the like, and in that case, it may be operated at an appropriate speed. In any case, a large number of electric wire pieces connected in a "string of beads" shape with an adhesive tape are stored or transported in the form of a coil, and the tape is cut with a cutter or scissors at the shipping site, one by one. It will be separated for use in wiring work.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Number (10) in FIG. ) Shows an endless belt rotating to travel toward (). This Belt (10)
Is made of, for example, semi-hard rubber.

The endless belts (10) and (10) have an inlet (A) and an outlet.
(B) is arranged on both sides of the conveyor center line in the direction of connecting, the drive is friction type by rollers (13), (13) on the outlet side fixed to a common axle (12) The rollers (14), (14) on the inlet side are free-rotating rollers mounted on the axle (15). For example, the wire piece (D) with the terminal (T) attached to the bare end by a crimping machine (not shown) has a belt (10), () located slightly before reaching the apex of the outer peripheral surface of the inlet side roller (14). It is supplied as a bridge between the parts of 10), but since there is a lower tape there, there is no risk of falling from the conveyor.

The feed claws (11) protruding from the outer surface of the endless belt (10) at equal intervals are made by adhering a plastic strip to the rubber material in this example, but are formed integrally with the rubber material. You can In the process of returning to the entrance side along the lower route (10b), these feed claws (11) have no effect,
Of course, it is in the "idler" state.

Each feeding claw (11) of each belt has a posture that intersects with a line connecting the conveyor inlet and outlet,
The left and right corresponding feed pawls (11), (11) are in line with each other.

From the first feeder (31) provided with the supporter (31a) for rotatably supporting the core of the adhesive tape, the arrow (Y
1) Lower adhesive tape supplied from below as in (Fig. 1)
(21) slides on the surface of a substantially L-shaped corner rounding turning guide (33) located outside the conveyor entrance and turns to the exit side while sliding on the surface, specifically, Enters the traffic area between the endless belts (10) and (10). This pull-in is performed by the propulsive force of the feed claw (11) via the wire piece after the device enters the steady operation state, but at the time of start-up, the operator pulls the hand with the hand to the outlet side and You have to stick it. The number (34) indicates a pair of ridges for preventing tape roll.

Turning guide (33) on which the lower tape (21) slides
The upper surface of the is flush with the upper surface of the belt (10) in the upper path (10a), or slightly below. Therefore,
The entry of the wire piece is smooth and sticks immediately after entry (precisely before reaching the pressing means) to the upward sticking surface of the tape.

On the other hand, from the upper side of the endless belt (10), the arrow
As shown in (Y2) (Fig. 1), the upper adhesive tape (22) with the adhesive surface facing downward is located slightly inward from the entrance.
It is supplied from the second feeder (32) via 5) and adheres to the wire piece at that position. Thus, the electric wire pieces (D), (D), which are advanced in parallel by the feed claws (11), (11), which are advanced along the upper path (10a) of the conveyor, are mixed with the pressing means (40) described below. And both tapes (21) and (22) are kept parallel to and substantially flush with the upper path. The turning guide (35) for the upper tape is a free-rotating roller held by the support shaft (36) at a constant height. Like the first feeder, the second feeder (32) is also provided with a supporter (32a) that rotatably supports the core of the adhesive tape.

In this way, the tapes (21), (2) that sequentially adhere to the electric wire pieces (D), (D) ... the upper peripheral surface portion and the lower peripheral surface portion.
2) is pressed from above and below by the pressing means (40) in the area between the adjacent electric wire pieces before reaching the outlet (B), and the adhesive surfaces of the areas where the electric wire pieces do not exist are "directly" joined to each other. At the same time, it is more surely adhered to the wire piece.

The pressing means (40) is attached in the respective approaching directions by springs (43) and (44) whose spring elastic coefficients are adjusted so that they come into contact with each other at the height of the central axis of each electric wire piece (D). As a biased pressing member, a free-rotating small roller (41),
It is equipped with (42). As seen in Figure 2, the entrance
In order to prevent the electric wire piece from sticking to the adhesive tape in the section from (A) to the pressing means (40) excessively strongly, the lower tape (21) is given a slight upward slope and the upper tape (22).
Conversely, both guides (33), (3
A mechanism (not shown) that can finely adjust the height of 5) is also attached.

[0021] Thus, the group of "ross-tie" electric wire pieces bonded and integrated with the tape is connected to the discharge slide plate (50) having the downward slope (51) arranged in the vicinity of the conveyor outlet (B). Transferred from the device and continuously exiting the device.

Although the representative embodiments of the present invention have been described above, the present invention is not necessarily limited to only these embodiments, and has the above-mentioned constitutional requirements of the present invention, achieves the object of the present invention, and is as follows. It can be appropriately modified within a range that has an effect. For example, contrary to the embodiment, the turning guides are arranged so that the upper adhesive tape is parallel to the upper path outside the conveyor inlet, and the upper adhesive tape is correspondingly parallel to the upper path slightly inward of the inlet. The turning guide may be arranged so that In that case, the receiving plate may be arranged near the conveyor so that the electric wire does not drop at the entrance.

[0023]

According to the wire piece aligning and pasting device of the present invention, it is not necessary to rely on manual work to pack and pack an extremely large number of wire pieces for each wire type or each conductive terminal type. Not only can the same type of electric wire or an electric wire with a terminal of the same type be efficiently performed, but in some cases, it can be automatically performed as the final step that is part of the crimping work, etc. All undesired problems such as congestion and confusion at the work site can be avoided. The device of the present invention uses an electric wire having such a shape.
Has an effect that can be easily and surely obtained by simple means.
