DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel for winding cords, and an automatic winding device and an automatic terminal stopping device for cords suitable for using the reel.

[0002] Cords (or cords) are linear bodies (including stranded wires) called various names such as steel cords, filaments, metal wires, wires, ropes, steel cords, synthetic resin wires, ropes, strings, and the like. Means any material.

[0003]

2. Description of the Related Art After winding cords, particularly metal cords having high elasticity, onto a reel, it is necessary to fix the terminal portion of the cord to an appropriate position on the reel. One structure for stopping the terminal portion of the cords is described in Japanese Utility Model Laid-Open Publication No. 3-62069.

[0004] In this method, a long hole from which a terminal portion of cords can be drawn is formed on the outer peripheral edge of the flange of the reel, and a clip, a spring or the like (an engaging member) is formed on the outer surface of the flange at a position close to the long hole. Stop piece). The ends of the cords (portions slightly returned from the ends) are plastically deformed into a U-shape or a V-shape, drawn out through the elongated holes to the outside of the flange, and the drawn bent portions are stopped with clips.

In the case of this structure, the terminal portion of the cords must be drawn out through a long hole, so that the terminal fixing work is complicated and unsuitable for automation thereof. Further, since the cords are bent in a U-shape or a V-shape, a considerably long portion is wasted.

[0006] Since there was no reel suitable for automating the terminal stop, it is a matter of course to realize a device that can automatically stop the terminals of the cords and a winding device for the cords including such an automatic terminal stop device. I didn't.

The present invention provides a cord automatic winding device including the above-mentioned terminal stopping device.

According to a first aspect of the present invention, there is provided a cord winding reel according to the present invention, wherein flanges are provided at both ends of a winding drum, and a cord holding piece made of an elastic material is provided near an outer peripheral edge of at least one of the flanges. The cord holding piece is provided with a central holding finger, fixed fingers provided on both sides thereof, and a connecting portion for connecting the pressing finger and the fixed finger, and a tip and a connecting portion of the fixed finger are provided. The upper and lower edges of the window come into contact with the outside of the flange, and the tip of the fixed finger is swaged and fixed by the folded portion of the outer periphery of the flange.
The center pressing finger has a tip portion along the inner surface of the outer peripheral edge portion of the flange, and cords are sandwiched and fixed between the tip portion and the inner surface of the outer peripheral edge portion of the flange.

According to a second aspect of the present invention, there is provided a cord winding reel according to the present invention, wherein flanges are provided at both ends of a winding drum, and a window is formed near an outer peripheral edge of at least one of the flanges. A cord holding piece made of a body is attached. The cord holding piece includes a center pressing finger, fixed fingers provided on both sides thereof, and a connecting portion for connecting the pressing finger and the fixed finger. A connecting portion is provided along the outer surface of the flange on the left and right of and below the window, and the tip of the fixing finger is swaged and fixed by a folded portion of the outer peripheral edge of the flange. Is located along the inner surface of the outer peripheral edge of the flange, and has a curved central portion protruding from the window to the outside of the flange. In which the cords between the sides is sandwiched fixed.

The reels for winding up cords defined from the first viewpoint and the reels for winding cords defined from the second viewpoint are summarized as follows. That is,
In the reel for winding cords according to the present invention, a flange is provided at both ends of the winding drum, and a window for accommodating a cord holding piece made of an elastic body is formed near at least one outer peripheral edge of the flange. Has a center pressing finger, fixed fingers provided on both sides thereof, and a connecting portion for connecting the pressing finger and the fixed finger, and a tip of the fixed finger is fixed by caulking by a folded portion of an outer peripheral edge of the flange. ,
The center pressing finger has a tip portion along the inner surface of the outer peripheral edge portion of the flange, and cords are sandwiched and fixed between the tip portion and the inner surface of the outer peripheral edge portion of the flange.

According to the cord winding reel according to the present invention, after the cords are wound on the reel, the pressing finger at the center of the cord holding piece is pressed from the outside with the operator's finger or a part of the machine. A gap is formed between the tip of the presser finger and the inner surface of the outer peripheral edge of the flange. When the terminal portion of the cords is inserted into this gap, the terminal portion of the cords is sandwiched and fixed between the tip of the pressing finger and the inner surface of the outer peripheral edge of the flange. Therefore, the work of fixing the terminals to the codes is easy. In addition, since the cord holding piece is formed of an elastic body, the terminal portion of the cords is securely fixed by the elastic force. In the reel of the present invention defined from the second point of view, the pressing finger at the center of the cord holding piece is curved outward and protrudes outward from the flange, so that it is easy to press this part.

Since the pressing finger at the center of the cord holding piece can be pushed by a pusher or other members of the machine, not only the winding of the cords on the reels but also the terminal stopping of the cords is automatically carried out by the machine. Will be able to do it. The automatic terminal stopping device will be described later.

The tip of the pressing finger at the center of the cord holding piece extends along the inner side surface of the outer peripheral edge of the flange, and the terminal portion of the cord is fixed at this portion. There is little possibility that the terminal portion jumps out.

If the terminal portion of the cords wound on the reel has only a small length, it can be guided to the position of the cord holding piece. Is short and economical.

The cord holding piece can be attached to the flange simply by caulking and fixing the tip of the fixed finger by the folded portion of the outer peripheral edge of the flange, so that the assembly is simple and can be provided at low cost.

The connecting portion of the cord holding piece only contacts the lower edge of the window from outside the flange. When this connecting portion is fixed by welding or the like, stress concentrates near the fixing portion, and the cord holding piece is easily broken. In the present invention, since the connecting portion is not fixed, the stress generated by holding the cord terminal portion is dispersed, the life of the cord holding piece is extended, and the elasticity for holding the cord terminal portion is also increased.

In one embodiment of the present invention, a recess for accommodating the tip of the pressing finger is formed on the inner side surface of the outer peripheral edge of the flange along which the tip of the pressing finger of the cord holding piece extends. Since the pressing finger of the cord holding piece can be accommodated in the recess, the pressing finger does not become an obstacle when the cords are wound around the reel.

In another embodiment, a depression for accommodating at least a part of the cords is formed at the tip of the pressing finger of the cord holding piece. Since a depression is formed in the pressing finger of the cord holding piece, the terminal portion of the cords is securely fixed and hardly detached by fitting the terminal portion of the cords into the depression. Also, even when the terminal portion of the cords is sandwiched, the pressing finger is not bent so much inward, so that no excessive force is applied near the base thereof, and the possibility of weakening or breaking near the base is low. Become.

The portion of the cord holding piece held by the pressing finger is not the terminal (tip) of the cords, but is a place slightly returned from the tip. The code terminals are in a state where they can move freely.

Therefore, it is preferable to form a cord terminal holding portion on the outer peripheral edge of the flange at a position at a suitable distance from the cord holding piece in the cord winding direction along the outer peripheral edge of the flange.

The terminals of the cords can be securely fixed by the terminal holding section. It is possible to prevent accidents caused by the code terminals jumping out (such as striking an operator's eyes or damaging them by contacting other reels during transportation).

The cord holding pieces may be provided on the two right and left flanges of the cord winding reel, respectively. Similarly, the cord terminal holder can be provided on each of the two flanges. In this case, after the cords are wound on the reel in one direction, the positional relationship between the cord holding pieces and the cord terminal holding portions is determined so that the terminal portions of the cords can be held on either of the left and right flanges. Good.

It is preferable that the cord holding piece is an elastic body as hard as possible. More preferably, the cord retaining piece is formed of carbon tool steel. Its hardness is Rockwell hardness H
It is at least Rc27, more preferably at least HRc30. The cord holding piece can be made harder by heat treatment (quenching and subsequent tempering).

The present invention provides an apparatus for winding cords around the above-mentioned reel and automatically stopping the terminal.

The automatic winding apparatus for cords according to the present invention is supplied by transferring and transferring a reel from a cord winding position to a terminal stop position, and by holding and rotating the reel at the cord winding position. A first holding and rotating mechanism for winding the cords, a traverse roll for reciprocating the cords supplied to the reel at the cord winding position in the axial direction of the reel, and a second holding the reel at the terminal stop position.
A pusher for pushing a pressing finger of a cord holding piece provided on a reel held by the second holding mechanism into the reel, and separating a tip end of the pressing finger from a flange of the reel; By pressing a portion of the cords wound on the reel held by the holding mechanism 2 extending in the direction of the traverse roll, a part of the cords is moved between the tip of the pressing finger and the flange. Cord holding means is provided.

The cords are wound around the reel at the cord winding position. The reel on which the cords are wound is transferred to the terminal stop position. Here, the pressing finger of the cord holding piece provided on the reel is pressed by the pusher, and the terminals of the cords are put into the gap between the tip of the pressing finger and the flange of the reel. In this manner, after the cords are wound around the reel, the terminals of the cords can be automatically fixed to the reel without manual operation.

In one embodiment, the cords are cut between the end portion of the pressing finger and the flange at a position between the cord winding position and the terminal stopping position, and then the cords are cut. A cutter is provided.

Before the cords are cut by the cutter in preparation for winding the cords on the empty reel at the cord winding position, the first holding / rotating mechanism causes the start end of the cords to move to the reel. Hold it between the flanges.

The cord terminal stopping device according to the present invention used in the cord automatic winding device described above is a sensor for detecting the position of the cord holding piece provided on the reel, and the pressing finger of the cord holding piece is attached to the reel. Pushing inward, pushing the tip of the presser finger off the flange of the reel, holding the reel around which the cords are wound, and rotating the reel until the sensor detects the position of the cord holding piece,
A reel holding and rotating mechanism for rotating the reel until the pressing finger of the cord holding piece reaches the position opposing the pusher; and a part of the cord extending from the reel to the cord supply side is formed by the tip of the holding finger and the flange. Means for moving the cords in a direction between them.

First, the position of the code holding piece of the reel is detected by the sensor, and the reel is rotated until the pressing finger of the code holding piece reaches the angular position facing the pusher. In this way, the pusher can reliably press the presser finger, and the reliability of stopping the cords at the terminals is improved.

If necessary, a cutter is provided, and after a part of the cords is sandwiched between the tip of the pressing finger and the flange by the cutter, the cords are cut on the supply side.

In a preferred embodiment, a mechanism is provided to allow the cords to be supplied without causing slack when the reel is rotated by the reel holding and rotating mechanism.

[Explanation of the embodiment]

First Embodiment FIGS. 1 to 8 show a first embodiment of a cord winding reel according to the present invention.

In FIG. 1, the reel for winding up cords comprises a cylindrical winding drum 1 and disk-shaped flanges 2A and 2B attached to both ends thereof. The winding drum 1 and the flanges 2A and 2B are generally made of metal, and the flanges 2A and 2B are fixed to the winding drum 1 by welding. The outer peripheral edges of the flanges 2A and 2B are folded outward (the folded portions are indicated by reference numeral 3). In addition, flange 2
A plurality of reinforcing ribs 4 are integrally formed radially on A and 2B. The rib 4 protrudes on the outer surface of the flange and is recessed on the inner surface.

In one flange 2A, a window 5 is formed near the outer peripheral edge thereof (particularly, see FIG. 4). The upper edge (outer edge) of the window 5 substantially coincides with the inner edge of the folded portion 3. On the inner surface of the folded portion 3, a depression 3a is formed at a position corresponding to the center of the window 5 in the width direction. The window 5 accommodates a cord holding piece 10 described below.

As shown in FIGS. 5 (A) and 5 (B), the cord holding piece 10 has a center pressing finger 11, fixed fingers 12 and 13, spaced apart from each other on both sides thereof. Further, a connecting piece 14 for connecting the holding finger 11 and the fixed fingers 12 and 13 at their lower portions is provided. The cord holding piece 10 is formed of an elastic body such as steel (preferably, carbon tool steel described in the second embodiment).

The center pressing finger 11 is the longest, and its tip is curved outward (to the right in FIG. 5B).
In the vicinity of this tip, a dent 11
a is formed in the width direction. The recess 11a is large enough to fit at least a part of the terminal portion of the cords.

The connecting portion 14 is bent outward at right angles from the lower ends (bases) of the holding finger 11 and the fixed fingers 12 and 13, is bent again at a right angle with a small width, and extends in parallel with the fingers 11 to 13. Similarly, the tips 12a and 13a of the fixed fingers 12 and 13 are also bent outward at right angles, bent again at right angles with a slight width, and extend in parallel with the central portions of the fingers 12 and 13. The width of the bent portion is substantially equal to the thickness of the flange 2A.

Outer edge of fixed finger 12 of cord holding piece 10 and fixed finger
The spacing between the outer edges of the thirteen is approximately equal to the width of the window 5. The length from the right-angled bent portion of the fixed fingers 12 and 13 to the right-angled bent portion of the connecting portion 14 is substantially equal to the height of the window 5.

The cord holding piece 10 having such a configuration is similar to that of FIG.
As shown in the figure, the lens is housed in the window 5 and fixed to the flange 2A.

From the outside of the flange 2A, the cord holding piece 10
Insert the tip of the center presser finger 11 through the window 5 into the flange 2
The holding finger 11 and the fixed fingers 12 and 13 are put into the window 5 so as to be along the inner surface of the outer peripheral edge portion (the folded portion 3) of A. A gap is previously provided between the tip of the folded portion 3 and the outer surface of the flange 2A.
The tips 12a and 13a are along the outer surface of the upper edge of the window 5 and enter this gap. By strongly crimping the folded portion 3, the tips 12a and 13a of the fixed fingers 12 and 13 are strongly sandwiched between the folded portion 3 and the outer surface of the flange 2A, and are fixed. The connecting portion 14 of the cord holding piece 10 extends along the outer surface of the lower edge of the window 5. Since the tips 12a and 13a of the fixed fingers 12 and 13 and the connecting portion 14 are bent at right angles at two places with a small width as described above, the pressing finger 11 and the fixed finger 12
And 13 are substantially flush with the inner surface of the flange 2A in the window 5.

The recess 3a is formed on the inner surface of the outer peripheral edge of the flange 2A as described above. The tip of the pressing finger 11 housed in the window 5 is housed in the depression 3a. As a result, the tip of the presser finger 11 also does not protrude (or hardly protrudes) inside the inner surface of the outer peripheral edge of the flange 2A. When winding cords on reels, presser fingers
The 11 tips do not get in the way.

The connecting portion 14 of the cord holding piece 10 is a flange 2A
This portion 14 is not fixed to the flange 2A by fixing means such as welding, rivets, etc., merely by contacting the outer surface of the flange 2A. If the connecting portion 14 is fixed to the flange 2A, stress tends to concentrate on the lower end of the pressing finger 11 (near the boundary with the connecting portion 14) when the end of the cords is fixed with the pressing finger 11. . When used for a long time, the lower end of the presser finger 11 becomes fatigued and is easily broken. The stress generated when holding the end parts of the cords is as follows:
By not fixing the cord holding piece 10, the cord holding piece 10 is dispersed throughout the vicinity of the connecting part 14, the lower end of the pressing finger 11, and the lower end of the fixed fingers 12 and 13, thereby extending the life of the cord holding piece 10. Also, presser finger
The spring property for holding the cord terminal portion by 11 is also improved.

As best shown in FIGS. 1, 2 and 4, the flange 2A is slightly smaller (for example, 10 to 20 cm) in the cord winding direction than the position where the cord holding piece 10 is provided.
At an approximately (distant) position, an elongated hole (cord terminal holding portion) 20 for holding a cord terminal is formed in the outer peripheral edge (returned portion 3) of the flange 2A.

When a suitable amount of cords are wound around the winding drum 1 of such a reel and the terminal portion is fixed,
As shown in FIG. 7, the pressing finger 11 of the cord holding piece 10 is pressed inward from the outside of the flange 2A by the operator's finger. Then, the tip of the presser finger 11 separates from the inner surface of the outer peripheral edge of the flange 2A to form a gap. When the terminal of the cords to be fixed is inserted into this gap and the pressing of the pressing finger 11 is released, the pressing finger 11 returns to its original state due to its elasticity, and the distal end of the pressing finger 11 and the inner peripheral surface of the flange 2A. The terminal C of the cords is sandwiched and fixed between them (see FIG. 8).

A depression is formed at the tip of the holding finger 11 of the cord holding piece 10.
Since the terminal 11a is formed, the terminal portion of the cords is securely fixed and hardly detached by fitting into the recess 11a. In addition, even when the terminals of the cords are sandwiched, the holding finger 11 does not bend too much inward, so that no excessive force is applied near the lower end, and the possibility of weakening or breaking near the lower end is low. Become. As mentioned above,
Since 14 is not fixed, the stress applied to the pressing finger 11 is dispersed.

The leading end (the end of the cords) of the cords held by the pressing finger 11 is inserted into the elongated hole 20 as shown in FIG. As a result, it is possible to prevent an accident (such as striking an operator's eyes or contacting another reel during transportation) caused by the code terminals jumping out.

When pressing the terminal portion of the cords with the press finger 11, instead of pressing the press finger 11 inward with the finger of the operator as described above (as shown in FIG. 7), Then, it can be pushed by a part of the machine (push rod, pusher, etc.). That is, not only the cords are wound around the reels, but also the terminals can be automatically stopped by the machine. The automatic terminal stopping device will be described later.

The terminal holding slot 20 need not always be provided. The cord holding piece 10 may be provided on the other flange 2B in addition to the flange 2A. In this case, the terminal holding slot 20 can also be formed in the flange 2B. When the cord holding pieces 10 (and the terminal holding holes 20) are provided on both the flanges 2A and 2B, respectively, the ends of the cords wound in one direction are attached to both the left and right flanges 2A and 2B. It is preferable to determine their positional relationship so that they can be locked.

Second Embodiment FIGS. 9 to 12 show a second embodiment of a cord winding reel according to the present invention.

In FIG. 9, the reel for winding the cords comprises a cylindrical winding drum 1 and disk-shaped flanges 2A and 2B attached to both ends thereof, as in the first embodiment. .

The winding drum 1 is firmly formed by two cylinders, an outer cylinder 1A and an inner cylinder 1B. Flanges 1C fixed to both ends of the inner cylinder 1B of the winding drum 1 are fixed to the flanges 2A and 2B by welding. A triangular hole 7 is formed substantially at the center in the length direction of the outer cylinder 1A of the winding drum 1. The hole 7 is used to insert a tip of a cord or the like to be wound and to lock it. Because the hole 7 is triangular,
The winding direction (direction from the base of the triangle to the vertex) is also shown. This hole 7 is not always necessary. The inner cylinder 1B of the winding drum 1 is used for attaching the reel to a take-up shaft (a spindle or a tail stock described later) or a rewind shaft. Hole 1D formed in flange 2A (and 2B) and 1C around inner cylinder 1B
Is used for inserting a pin for rotating and driving the reel, particularly in winding of cords.

As in the first embodiment, a plurality of radial reinforcing ribs 4 are formed on the flanges 2A and 2B. In this embodiment, a window 6 is formed at a position substantially corresponding to both flanges 2A and 2B. These windows 6
The upper edge (outer edge) is also located at a position substantially coincident with the inner edge of the folded portion 3 of the flanges 2A and 2B. At a position separated from the position of the window 6 by an appropriate length in the winding direction, the flange 2
An elongated hole 20 for holding a code terminal is formed in the outer peripheral edge portion (turned portion 3) of A and 2B.

It is preferable to clearly indicate the winding direction of the cords on the outer surfaces of the flanges 2A and 2B as indicated by an arrow 8. In addition, a mark as shown by an arrow 9 may be provided so that the position of the code terminal holding hole 20 can be recognized. The position of the window 6 (code holding piece 30) may be clearly indicated in the same manner (useful for detection by a code holding piece sensor described later). These arrows 8 and 9 can be provided by forming projections in the form of arrows on the flanges 2A and 2B, or the seals with the arrows printed on the flanges 2A and 2B.
You may provide by attaching to A and 2B.

The fixing action of the cord holding piece 30 attached to the window 6 and the end of the cords using the cord holding piece 30 is the same in both the flanges 2A and 2B. The code holding piece 30 will be described.

As shown in FIGS. 10 (A) and 10 (B), the cord holding piece 30 has a center pressing finger 31 and fixed fingers 32 provided on both sides of the pressing finger 31 at a distance. 33, and a connecting piece 34 for connecting them. The cord holding piece 30 is formed of a hard elastic body.

Preferably, the cord holding piece 30 is made of carbon tool steel J
IS SK5 (ISO TC90, TC80) (AISI
It is made according to ASTM W1-8). JIS SK
5 has a composition of C0.8-0.9 (W%), Si0.35 or less, Mn
0.50 or less, P0.03 or less, S0.03 or less, and the balance is Fe. Preferably, the hardness and spring property are increased by heat treatment. For example, carbon tool steel SK5 was quenched at 820 ° C for 45 minutes, then tempered at 570 ° C for 60 minutes, and then air-cooled. As a result, Rockwell hardness HRc30 or more was secured. The heat treatment by quenching and tempering is characterized in that the obtained hardness has a small variation. Experiments have shown that a rock well hardness of HRc27 or more is sufficient for practical use. Preferably rockwell hardness HRc
30 or more. Cord holding piece with such high hardness
If 30 is used, the fixing ability and durability of the cord terminal will be excellent.

The center pressing finger 31 is longer than the other fixed fingers 32 and 33. A semicircular or arcuate pressing portion 31b is formed at the center in the length direction of the pressing finger 31. The length of the pressing portion 31b is slightly shorter than the height of the window 6 formed in the flange 2A. The width of the pressing finger 31 is formed slightly smaller than the width of the window 6. The presser finger 31 as a whole is
b is slightly warped in the protruding direction (to the right in FIG. 10 (B)).

The tips 32a and 33a of the fixed fingers 32 and 33 are
It is slightly curved in a direction opposite to the direction in which the pressing portion 31b of the pressing finger 31 protrudes (to the left in FIG. 10B).

The cord holding piece 30 is fixed to the flange 2A as shown in FIG. From the outside of the flange 2A, the tip 31a of the holding finger 31 is brought into the inside of the flange 2A through the window 6, and the fixed fingers 32 and 33 and the connecting piece 34 are connected to the window 6A.
Around the outer surface of the flange 2A. Fixed finger
The distal ends 32a and 33a of 32 and 33 enter the gap between the distal end of the folded portion 3 and the outer surface of the flange 2A. Since the folded portion 3 is bent slightly inward from the outer edge of the flange 2A, the curved tips 32a and 33a of the fixed fingers 32 and 33 follow the inner surface of the slightly curved folded portion 3.

By strongly caulking the folded portion 3,
The tips 32a and 33a of the fixed fingers 32 and 33 are strongly sandwiched between the tip of the folded portion 3 and the outer surface of the flange 2A, and the cord holding piece 30 is fixed to the flange 2A. Pressing part of presser finger 31
31b protrudes from the window 6 to the outside of the flange 2A. It is preferable that the caulking operation is performed while the cord holding piece 30 is temporarily fixed to the outer surface of the flange 2A with an adhesive or the like.

The cord holding piece 30 is formed of a hard material. When swaging the folded part 3 strongly,
The tip 31a of the thrust finger 31 slightly deforms the folded portion 3, and a small recess 3b for accommodating the tip 31a is formed on the inner surface of the folded portion 3. The tip of the presser finger 31
31a is slightly curved along the depression 3b of the folded portion 3. Further, since the pressing finger 31 is entirely warped with respect to the connecting piece 34, the tip 31a is strongly pressed against the recess 3b of the flange 2A. Since the tip 31a of the pressing finger 31 does not protrude inward of the flange 2A, the tip 31a does not hinder the operation of winding the cords on the reel.

It goes without saying that the depression 3b of the folded portion 3 and the curvature of the tip 31a of the pressing finger 31 may be formed in advance.

When a suitable amount of cords are wound around the winding drum 1 of such a reel and the terminal portion is fixed,
Press the pressing portion 31b of the pressing finger 31 of the cord holding piece 30 with the flange 2A.
Press inward with the operator's finger from outside. Then, presser finger 31
Is the outer peripheral edge of the flange 2A (the folded portion 3)
A gap is formed away from the inner surface. When the terminal of the cords to be fixed is inserted into this gap and the pressing of the presser finger 31 is released,
The presser finger 31 returns to its original state due to its elasticity.
The terminal portion C of the cords is sandwiched and fixed between the front end portion 31a and the inner peripheral surface of the outer periphery of the flange 2A (see FIG. 12).

Also in this embodiment, the connecting portion 34 of the cord holding piece 30 is only in contact with the outer surface of the flange 2A, and this portion 34 is fixed to the flange 2A by fixing means such as welding or rivets. There is no. Therefore, the stress generated when the ends of the cords are held is dispersed throughout the connection part 34, the lower end of the holding finger 31, and the lower ends of the fixed fingers 32 and 33, and the life of the cord holding piece 30 is extended. become longer. Further, the spring property for holding the cord terminal portion by the pressing finger 31 is also improved.

The leading end (the end of the cord) of the cord held by the pressing finger 31 is inserted into the slot 20.

Instead of pushing the holding finger 31 inward with the finger of the operator, the holding finger 31 may be pushed by a part of the machine (such as a push rod). In addition to the winding of the cords on the reels, the terminal can be automatically stopped by a machine, as is the case with the cord winding reel of this embodiment.

The cord holding piece 30 and the long hole 20 are connected to the flange 2
Needless to say, it may be provided in only one of A and 2B. The pressing finger 31 of the cord holding piece 30 may be formed with a depression into which the terminal portion of the cords corresponding to the depression 11a of the first embodiment fits.

And a pusher 74 are provided. When the reel 40Z at the clamp position Z rotates, the sensor 73 and the pusher 74 both
It is located at a position facing the path through which 30 passes.

The sensor 73 is, for example, a reflection type photoelectric sensor, and detects the code holding piece 30 based on the fluctuation of the reflected light. When the projection light of the sensor 73 is projected on a portion of the reel flange 2A near the outer periphery where the reinforcing rib 4 is not provided, the reflected light intensity is substantially constant even if the reel rotates. There is a window 6 in a portion where the cord holding piece 30 is provided. The pressing finger 31 of the cord holding piece 30 is curved.
Since the reflected light is small at this point, the cord holding piece 30
Is detected.

Instead of detecting the code holding piece 30 itself, the sensor 73 may detect a reflector or a mark provided near the code holding piece 30. Also,
The sensor 73 is not limited to a reflection type photoelectric sensor.

The pusher 74 presses the pressing finger 31 of the cord holding piece 30 and is driven by the air cylinder 75. The distal end face of the pusher 74 is preferably formed in a curved shape of the pressing finger 31, or an elastic body such as rubber is provided on the distal end face. The pusher 74 is located ahead of the sensor 73 in the rotation direction of the reel 40Z.

A cord holder 76 and a cutter 77 are provided between the clamp position Z and the winding position Y. The cord presser 76 is always slightly above the reel on the transfer mechanism 41, and is driven to move downward by a driving device (not shown) when the terminals of the cords are stopped.
The cutter 77 cuts cords. The cutter 77 is normally held at a position retracted laterally from the reel transfer path of the transfer mechanism 41.

Referring again to FIGS. 13 to 15, winding position Y
When winding the cords with the reel 40Y in
The spindle 61 and the tail stock 62 advance into the central hole of the inner cylinder 1B of the reel, and hold the reel. When the spindle 61 is rotationally driven, the reel also rotates to wind up the cords. At this time, the moving roll 52 of the adjusting device 50 is at the lower limit position. Since the clutch of the clutch / brake unit 54 is kept off and the brake is kept on, the moving roll 52 is kept at the lower limit position.

When the cords wound on the reel are full (or the cords of a predetermined length are wound) and the winding is completed, the traverse roll 49 is moved to a predetermined position (FIG. 14 or FIG. 17). At a position close to the spindle 61 as shown in FIG. Traverse roll extending from reel

Since the clutch of the clutch / brake unit 54 of the adjusting device 50 is off and the brake is also off,
With the transfer of the reel, the cords are pulled, the ball screw 55 is rotated by the force, and the moving roll 52 is raised. Spindle 71 and tail stock 72 are in the retracted position. The empty reel 40X at the standby position X moves to the winding position Y (this reel is indicated by reference numeral 40Y (40X)), and a new empty reel 40X is brought to the standby position X. This state is shown in FIGS. 16, 17 and 18.

The spindle 71 and the tail stock 72 advance and clamp the reel 40Z (40Y). The spindle 71 is rotationally driven in a direction for winding the cords. The code holding piece 30 is detected by the sensor 73 during at least one rotation of the reel. Since both the clutch and the brake of the clutch / brake unit 54 of the adjusting device 50 are kept off, the cords are pulled with the rotation of the reel, and the moving roll 52 further rises.

The relationship between the position of the sensor 73 and the position of the pusher 74 is predetermined. The reel 40Z (40Y) is further rotated by a predetermined angle from the angular position where the sensor 73 detects the code holding piece 30, and the code holding piece 30 is brought to a position facing the pusher 74. During this time, the moving roll 52 rises a distance corresponding to the rotation angle of the reel.

The air cylinder 75 is driven, and the pusher 74 pushes the pressing finger 31 of the cord holding piece 30 inward of the reel as shown in FIG. As a result, the tip 31a of the pressing finger 31 separates from the inner peripheral surface of the outer peripheral edge of the flange 2A, and a gap is formed between the inner peripheral surface and the inner peripheral surface.

Subsequently, the cord holder 76 is lowered to push the cords between the winding position Y and the clamp position Z downward. Get out of reel 40Z (40Y) and traverse roll 49
Since a part of the cords facing the inner side of the flange 2A is along the inner surface of the flange 2A, this part of the cords (which becomes the terminal portion C) is located between the tip 31a of the pressing finger 31 and the inner surface of the outer peripheral edge of the flange 2A. Into the gap. At this time, the moving roll 52 further moves up. Thereafter, the air cylinder 75 retreats and the pusher 74 returns, so that the pressing finger 31 returns to its original state by its elasticity. Cords 39 are the tip 31a of the presser finger 31 and the flange 2A.
Between the outer peripheral edge and the inner side surface. This state is shown in FIG.

Since the traverse roll 49 is stationary at a position outside the position of the reel flange 2A,
When the empty reel 40Y (40X) advances to the winding position Y,
The cords are on the outside of the flange 2A of this reel (Fig.
17).

Both the spindle 61 and the tail stock 62 advance to hold the reel 40Y (40X) at the winding position. Flange 60 of spindle 61 is reel 40Y (40X)
Over the flange 2A, and clamp the cords between the flange 60 and the flange 2A. Cutter
77 advances, the cord presser 76 and the reel at the winding position Y
The cords are cut at a position between 40Y (40X).

The reel 40Z (40Y) in which the cords have been wound up and the terminal portion C of which is stopped by the cord holding piece 30 is transferred to the next step, for example, a packing step or an aligning step.

In the adjusting device 50, the brake is turned off, the clutch is turned on, and the motor 53 is driven to rotate the ball screw 55, and the moving roll 52 is lowered to its lower limit position. Thereafter, the clutch is turned off and the brake is turned on.

At the winding position Y, the spindle 61 starts rotating, and the reels 40Y (40X) rotate, so that the cords are wound on this reel. The traverse roll 49 also reciprocates in the axial direction of the reel in synchronization with the rotation of the reel.

The leading end portions of the cords that are sandwiched between the flanges 2A and 60 and protrude outside are cut manually by a packing process or an aligning process after the terminal is stopped.
