Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a flat cable manufactured by integrally coating a large number of conductors, while the conductor portion is cut almost completely, The present invention relates to a flat cable cutter device capable of cutting perforations.

“Prior Art” Conventionally, in a flat cable manufactured by integrally coating a large number of conductors of this type, the conductor portion is cut almost completely, while the coating portion is cut into perforations (that is, No cutter device has been known that can leave the uncut portion in the coated portion in a perforated shape).

Here, the conventional method of winding a flat cable will be described. After measuring a flat cable continuously fed from the manufacturing apparatus side, an accumulator (a wire storage mechanism) composed of a plurality of rollers whose shafts can be separated from each other. ) Is used to wind the reel to the reel attached to the winder, and after the predetermined amount of flat cable has been wound onto the reel, the flat cable is cut and newly wound onto an empty reel. I have to.

In the conventional flat cable cutter device used in such a winding device, the flat cable is completely cut (both the conductor wire and the covering material) at the cutter device portion. , And manually collect the existing reel on which the flat cable has been wound, and attach a new reel to the winder.
After winding the end of the cut flat cable around this, the winder is restarted to wind the reel on a new reel.During that time, the flats continuously sent from the manufacturing equipment side. Since it is necessary to temporarily stop the cable from being sent to the winder side, the shafts of the rollers of the accumulator mechanism are separated from each other, thereby absorbing the flat cable during traveling, I am trying to do the work.

"Problems to be solved by the invention" However, in the conventional flat cable cutter device, the flat cable is completely cut at that time. While it is necessary to secure a certain amount of work time, there is a limit to the accumulated dose of the accumulator for temporarily stopping the feeding of the flat cable to the winder side, and during the process of changing the reel, there is a limit. Once the speed is reduced and the reels have been replaced, the speed of the process may be restored to the original state.However, during this deceleration operation, an error may occur in the dimensions of the flat cable, and If you try to increase the accumulated dose of the accumulator in order not to change the speed of the accumulator, the accumulator becomes a large-scale facility. There were problems such as an increase in equipment costs.

The present invention has been made in view of the above problems, and when cutting with a cutter, the flat cable is not completely cut, and the uncut portion of the covering material is left in a perforated shape, and the winder is used. At the time of exchanging the reel in, the perforation is completely cut so that it is continuously wound on a new reel, during which the cable is continuously wound without affecting the speed of the process. It is an object of the present invention to provide a flat cable cutter device that does not require the accumulator or the like.

"Means for Solving the Problems" The present invention provides the above-mentioned problems by providing intervals between a plurality of conductor wires arranged in parallel in a flat cable and cutting blades at which a plurality of notches are formed at different intervals. Has been resolved.

[Operation] According to the flat cable cutter device of the present invention, since a plurality of notches of the cutting edge are formed at intervals different from the intervals of the conductors arranged in parallel in the flat cable, The position of the conductor does not have to be safely aligned,
Therefore, the position of the notch of the cutting blade and the position where the wall thickness of the covering material is thin do not completely coincide with each other, and the covering part is always left without being cut.

Next, a winding method using the flat cable winding device of the present invention configured as described above will be described.

The flat cable 1 continuously sent from a manufacturing device (not shown) first enters the measuring section A, and then the rollers 4, 5, 6
The feed length is measured by the rotary encoder 8 in a state where the slack is eliminated by being pulled with a predetermined tension by. The measured flat cable 1 is wound by the existing reel 25k sent to the winding section C via the cutter section B. Then, it is determined that the flat cable 1 is wound on the existing reel 25 by a sufficient amount.
In the double-sided tape sticking section 12 of the cutter section B, the flat cable 1 and the double-sided tape 2 are measured first.
The adhesive portion 2 is formed by attaching a. When sticking the double-sided tape, the running flat cable 1 is pressed against the sticking drum 14 by the roller 15, and the double-sided tape 2a sent from the double-sided tape sending section 13 is urged to the sticking drum 14 by the shaft 14a. By rotating the sticking drum 14, a predetermined amount of double-sided tape 2a is stuck to the flat cable 1 sandwiched between the sticking drum 14 and the roller 15. Then, when the sticking drum 14 rotates by a predetermined rotation angle and stops, the running force of the flat cable 1 and the adhesive force of the stuck double-sided tape 2a tear the double-sided tape 2a to a predetermined length, and FIG. As shown in, the double-sided tape 2a having a predetermined length is attached to the flat cable 1.

Next, when the flat cable 1 to which the double-sided tape 2a of a predetermined length is attached passes through the cutter device 16 arranged next to the double-sided tape attaching portion 12, the cutout portions 19a and 19a are formed.
are sandwiched between the rotating body 17 and the rotating body 18 to which the cutter 19 having the a, ... Formed is fixed, and as shown in FIG. 11, the perforated line 3 is formed at the substantially central portion of the affixed double-sided tape 2a. Is formed. In the present embodiment, as shown in FIG. 3, the space P between the conductors of the flat cable 1 is set.
₁ , P ₁ , ... And notches 19a, 19 of the cutter 19
Since the intervals P ₂ , P ₂ , ... Of a, ... Have different dimensions, the recesses 1x, 1x, ... Of the insulating coating material 1c of the flat cable 1 and the notches 19 of the cutter 19 are formed.
, 19a, ... Do not completely coincide with each other, and the depth 19d of the cutout portion of the cutting blade 19 is equal to the insulating coating material 1c.
Since the thickness is approximately the same as the thickness of the convex portion 1t of the
, k, 1k, ... are completely cut, but insulation coating 1
The shaded portions 1s, 1s, ... of c always remain in a perforated shape, and at this point the flat cable 1
Is never completely disconnected.

Then, at about the same time that the double-sided tape 2a is attached to the flat cable 1 on the cutter portion B and the perforations 3 are formed at the substantially central portion thereof, the turntable 23 starts to rotate in the winding portion C, Until then, the existing reel 25k that has wound the flat cable 1 and the empty reel 25s are exchanged. First, as shown in FIG. 6, the existing reel 25k and the empty reel 25s are positioned so as to be orthogonal to the direction in which the flat cable 1 is sent.
As 3 rotates, it approaches a parallel state as shown in FIG. 7, and as shown in FIG. 8, it becomes substantially parallel to the direction in which the flat cable 1 is sent. In this state, the adhesive portion 2 formed on the flat cable 1 comes into contact with the empty reel 25s near the perforations. In this state, since the existing reel 25k further rotates, the flat cable 1 is pulled between the empty reel 25s and the existing reel 25k, and cut at the portion of the perforation 3 formed on the adhesive section 2. The Rukoto. Then, one of the flat cables 1 cut at the perforations 3 is wound on the existing reel 25k, and finally the adhesive portion 2 is attached to the surface of the flat cable 1 so that slack does not occur and the flat cable 1 In the other one, the adhesive portion 2 adheres to the shaft portion of the empty reel 25s and is loosened, and the empty reel 25s starts to be wound with the rotation of the empty reel 25s. At that time, the ends of the flat cable 1 where the adhesive portion 2 is formed are the rotating arms 22a and 22b attached to the upper portion of the winding portion C.
By being pressed against the existing reel 25k and the empty reel 25s by this, the reel 25 is securely fixed.

Further, the existing reel 25k on which the flat cable 1 is wound is, as shown in FIG.
The hook 36a is housed in the winding portion 24 by driving the chuck air cylinder 38 and lifting it up, whereby the engagement between the hook 36a and the reel 25 is released. Then, the reel chuck 36 is attached to the winding shaft 29.
As shown in FIG. 15 when stored in a,
After removing the winding shaft 29a from the existing reel 25k and setting the existing reel 25k in a free state above the turntable,
As shown in FIG. 16, the shaft 51a of the reel discharge part 27
Is inserted into the through hole of the existing reel 25k,
By rotating the screw 50, the reel transfer device 51 is moved to the column 47 side, and as shown in FIG. 17, the existing reel 25k is moved to the elevating device 49 in which other existing reels 25k, 25k, ... Are stacked. Store.

Then, when the existing reel 25k is stored in the reel discharge part 27, the turntable 23 further rotates and returns to the original position as shown in FIG. 6, and the empty reel 25s continuously winds the flat cable 1. At the same time, a new empty reel 25s is supplied from the reel supply unit 26 to the portion where the existing reel 25k was disposed. Here, the supply method will be briefly described with reference to the drawing. First, as shown in FIG. 18, the lifting device is raised to move the empty reel 2 at the uppermost stage.
After the bottom of 5 s is positioned slightly above the upper surface of the turntable 22, the empty reel 25 s is linearly moved along the arm 42 while the empty reel 25 s is gripped by the starting part 46, whereby the empty reel The 25 s through hole is located at the through hole 23 a portion of the winding unit 24 of the rotary table 23.

When the empty reel 25s is positioned above the through hole 23a, as shown in FIG.
The winding air cylinder 40 is driven in a state where a is stored in the winding shaft 34a to insert the winding shaft 34a into the through hole of the empty reel 25s, and further, the chuck air cylinder 3
8 is driven to lower the reel chuck 36 so that the hook 36a is expanded outward from the slit 35 of the winding shaft 34a and engaged with the upper portion of the empty reel 25s. Fixed on top of.

In this way, by providing the new empty reel 25s on the turntable 23, even when the flat cable 1 is wound on the existing reel 25k by a predetermined amount, the empty reel 25s can be operated as described above. By replacing the existing reel 25k, the sent flat cable 1 can be continuously wound on the reel.

In addition, other embodiments other than the above or technical matters will be described below.

(i) In the above embodiment, the flat cable is used as the convex portion 1.
The present invention was applied to a corrugated plate-shaped cross section in which t and concave portions 1x are alternately formed. Of course, it can be applied to cases.

(ii) In the above-described embodiment, the cutter device is made to face two cylindrical rotating bodies 17 and 18, and one of them is provided with the cutting blade 19
Are fixed, and the flat cable 1 passing therethrough is sandwiched to cut the flat cable 1, but the invention is not limited to such a structure, and the cutting blade 19 may be one piece, and , Any device as long as it can cut the conductive wire portion almost completely and the covering material 1c portion with the cutting edge 19 having the cutout portions 19a, 19a, ... Good.

(iii) The intervals P2, P2, ... Of the notches 19a formed in the cutting edge 19 shown in the above embodiment are appropriately set according to the intervals P1, P1 ,. Needless to say, the design can be appropriately changed to the optimum size, and the shape of the cutout portion can be arbitrarily set.

As described above, the flutter and cable cutter device according to the present embodiment has a cylindrical shape in which the cutting blades 19 having the notches 19a formed at intervals different from the interval between the conductors 1k of the flat cable 1 are erected in parallel. Since it is fixed to one of the rotating bodies 17 and 18, the positions of the notch 19a of the cutting blade 19 and the conducting wire 1k do not completely coincide with each other.
The cutout portion 19a and the concave portion 1x of the flat cable 1 do not coincide with each other safely, and the covering material 1c always remains in a perforated shape without being cut. As a result, the flat cable is not completely cut at the cutter,
When changing the flat cable 1 from the reel 25k to the reel 25s, the flat cable 1 can be cut from the perforated portion by applying tension to the flat cable 1, and the reel replacing operation temporarily stops the winder. This is done without any need, and it is not necessary to temporarily stop the feeding of the flat cable that is continuously fed. for that reason,
Unlike conventional systems, equipment such as accumulators is not required, and it is no longer necessary to temporarily slow down the process or return to the original state when exchanging reels, which results in a flat cable during deceleration operation. It is possible to eliminate dimensional error.

"Effects of the Invention" As described above, the flat cable cutter device of the present invention is provided with cutting blades in which notches are formed at intervals different from the distance between the flat cable conductors. The notch and the position of the conductor wire do not completely match, that is, the notch and the part without the conductor wire do not completely match, and the uncut part remains in the covering part in a perforated shape. . As a result, the flat cable is not completely cut by the cutter device and can be easily cut by applying a predetermined tension at a predetermined place. For example, the flat cable is wound up. When replacing the existing reel with a new empty reel,
If it is cut from the perforated portion and continuously wound on an empty reel, the cable can be continuously wound without affecting the speed of the process during that time, and an accumulator or the like can be eliminated. .
