Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is a double-reel type wire winding machine that continuously winds various wire objects such as coated electric wires and communication wires at high speed over two winding reels. The present invention relates to a material winding machine that is capable of reliably and easily automatically pulling out the lower end line, which is the winding start end of an empty reel, to the outside of the reel circumference.

(Prior art) Two take-up reels are arranged side by side with their axes parallel to each other,
A double reel type wire material winding machine that repeatedly winds a wire material onto one reel via a traverse sheave, winds it fully, then cuts the wire material and continues to wind it onto the other take-up reel. Needless to say, this is well known, and the structure and function of the one disclosed in Japanese Patent Application Laid-Open No. 56-23174 will be explained as an example.

In FIG. 5, the two take-up reels 1 and 1' are
They are supported by the drive support parts 3, 4, 3', 4' in a removable and rotatable manner in opposite directions, and are arranged parallel to each other in the axial direction, and at one axial end of each reel 1, 1'. are provided with pawl wheels 5, 5' having claws 12, 12' on their respective circumferential sides for capturing the filament 2 and cutting the filament 2 through suitable cutting means. A traverse sheave 8 for feeding and guiding the linear material 2 to the reels 1 and 1' is movable between the reels 1 and 1', and is also movable between the reels 1 and 1'. The reels 1 and 1' are provided so as to be movable back and forth in the axial direction, and a line shifting lever 6 is also provided between the reels 1 and 1' so as to be movable back and forth in the axial direction of the reels.Continuous winding is carried out as follows. It is done. That is, when winding the linear material 2 onto one take-up reel 1, the traverse sheave 8 is positioned above the other take-up reel 1' side, and while the take-up reel 1 is rotated, the wire material 2 is wound through the sheave 8. feed the linear material 2 to the reel 1 side,
By reciprocating the sheave 8 in a straight line between a and b in the figure, the linear object 2 is reciprocated and sequentially moved from one axial end to the other end and from the other end to the other end on the circumference of the body of the reel 1. It is rolled up into layers. In this way, the take-up reel 1 is fully wound, the traverse sheave 8 is stopped at point a in the figure, and the wire material 2 is transferred to the take-up reel 1'. That is, as the position of point a of the traverse sheave 8 is moved, the wire material 2 is brought into a state of tangent to the inner surface of the pawl wheel 5' of the air reel 1' as shown in the figure through the movement of the line shifting lever 6, and the same As the reel 1' rotates (in the opposite direction to the rotational direction of the reel 1), the linear object 2 is engaged with the pawl 12' of the pawl wheel 5' accompanying the rotation, and an appropriate cut is made (not shown). The linear object 2 is cut at the position of the claw 12' by a means, and the cut end at the position of the claw 12' is the starting point on the air reel 1' side.
Rotation of empty reel 1' and traverse sheave 8
Through the upward movement of the full-wound reel 1 and the reciprocating movement of the sheave 8 between a and b, the wire material 2 is similarly wound around the body of the reel 1' in a laminated manner. be. During this time, on the full reel 1 side, reel 1
is removed and a new empty reel 1 is inserted, and when the empty reel 1' becomes full, next time the new take-up reel 1 is replaced and winding is carried out continuously in the same way. It will be done. In addition, in Figure 5, 9,
9' is the main terminal processing cover, 10 and 10' are auxiliary terminal processing covers, and these covers cover reel 1 on the full winding side.
for completely accommodating the cutting terminal extending around the circumference of the cutting terminal.

(Problems to be Solved by the Invention) In the prior art, as illustrated in FIG. Nail 1
Since the linear object 2 from the fully wound reel 1 side is cut at the position engaged with the reel 2', the cutting end remaining on the fully wound reel 1 side has a sufficient length from the circumference of the reel 1. The cut-off linear object 2 on the empty reel 1' has a starting end (output end) of a short length from the claw 12' to the circumference of the reel 1'. Moreover, this winding start end side is covered with the inner surface of the pawl wheel 5' by the wire material 2 which is wound in a sequentially laminated manner on the circumference of the reel 1' to form a full volume. Only the portion slightly engaged with the claw 12' is exposed.

This winding start end is generally called the lower opening or lower opening line, and the cutting end when the winding is full is called the upper opening or upper opening line, but if the lower opening line is too short, , the following disadvantages arise. In other words, in the case of such a double-reel type continuous winding machine, since winding is carried out alternately and continuously, errors may occur due to slippage of the measuring device used to measure the total length of the linear object during a series of winding operations. For this reason, a meter check is required.As is known, the meter check is performed by measuring and detecting the electrical conductor resistance and converting it. In use, it is extremely inconvenient that the exposed length of the lower opening (lower opening line) is short as described above.

(Means for Solving the Problems) In order to solve the above problems, the present invention extends the lower end wire to the outer circumferential side of the take-up reel at a sufficient length from the cutting position. The drawer does not interfere with the reel winding of the wire material at all, and it is designed to securely hold and expose the reel. Specifically, it has two winding reels that can be driven to rotate. are arranged in parallel with their axes parallel to each other, via a traverse sheave that feeds and guides the linear material to the take-up reel,
After winding a wire on one take-up reel, the wire is cut and can be continuously and alternately transferred to the other take-up reel, and the axis of each take-up reel is A double reel type wire material winding device, in which a chucking wheel is provided on one side in a direction so as to be rotatable together with the chucking wheel, and a locking member for locking the winding start end of the wire material is provided on the outer periphery of the chucking wheel. In the traversing machine, a bottom line drawing hook for hooking a linear object is provided on the outer periphery of the chucking wheel at a predetermined distance from the locking member toward the rear side in the rotational direction, and a hook for hooking a wire object is provided on the outer periphery of the chucking wheel. Therefore, the structure is such that a linear object can be hung on the hook.

(Function) According to the technical means of the present invention, as shown in FIG.
a, 21b are arranged in parallel with their axes parallel to each other, and both reels 21a, 21b are provided rotatably in opposite directions as shown by the arrows in the figure, as shown in FIG. The wire material 2 guided by the traverse sheave 25 is caught on the outer circumferential side of the chuck wheel 24 which is supported and can be rotated and stopped along with the reel, and the wire material 2 guided by the traverse sheave 25 is caught and cut into the wire material via the cutting hammer 26. A chucking plate 27 for cutting the object 2 is provided in a protruding manner, and a hook for pulling out the wire at the bottom end is also provided at a different position on the outer circumferential side of the foil 24 (on the rear side in the direction of rotation of the foil) for locking the linear object 2. By providing 28 in a similar protruding manner, the lower end wire can be secured outside the take-up reels 21a, 21b with a sufficient length in the following manner. That is, in FIG. 1, the wire material 2 is fully wound on the take-up reel 21a side,
The reel 21a is stopped, and the reel 21a is stopped.
The winding reel 21 on the empty winding side is connected to the linear object 2 extending from the full winding side of 1a to the traverse sheave 25.
When b rotates counterclockwise as shown by the arrow in the figure, the chucking plate 27 protruding from the outer circumferential side of the reel 21b and the chucking wheel 24 that is coaxial with the reel 21b rotates. , shows a state in which the linear object 2 is hooked and chucked at the position of the claw portion 27a, and the reel 21 is once hooked at the position where the chucking plate 27 corresponds to the position of the cutting hammer 26.
b is stopped, and then the traverse sheave 25 is moved to the center position as shown in FIG. At the rear of the sheave 27, the sheave 25 is placed on the left side in the drawing than the hook 28 for drawing out the lower line that protrudes outside the reel 21b, and then in this position, the sheave 25 is moved rearward in the vertical direction in the drawing. be. That is, to explain this with reference to FIG. 4, the traverse sheave 25 at the position 25a in the same figure is moved rearward to the position 25b in the same figure, and thereby the hook 2
The tracking plate 2 is retracted from position 8.
As shown in FIG. 4, the portion of the linear object 2 extending between the sheave 25 and the sheave 25 moves from the position 2a to the position 2b, and changes to a position directly facing the hook 28 for drawing out the lower wire. Next, as shown in FIG. 3, the linear object between the tracking plate 27 and the sheave is removed by moving the traverse sheave 25, which has been moved to the center position in FIG. 2, to its original position as shown in FIG. The second part is
As shown in the figure, the traverse sheave 25 is securely engaged with the hook 28 for pulling out the lower wire in a cross-shape manner, and in this state, the traverse sheave 25, which is in the position shown in the figure, is moved vertically forward in the figure. In this state, the sheave 25 at the position 25b is moved to the position 25a in FIG.
The part of the wire 2 that changes from the b position to the 2c position, is locked to the hook 28 without fear of coming off, and is held between the hook 28 and the chucking plate 27 becomes the lower opening line 29. . This first,
After the lower end wire take-out operation shown in FIGS. 2 and 3, by rotating the take-up reel 21b on the empty winding side in the direction of the arrow in the figure, the wire material 2 is removed from the plate as the chucking plate 27 passes the hammer 26 position. 27 claws 2
cut via the hammer 26 at position 7a;
The wire material 2 is separated from the full winding side, and the traverse sheave 2
forward and backward reciprocating movement along the axial direction of the reel 21b of No. 5;
Further, through the continuous rotation of the reel 21b, the wire material 2 that has been wound is sequentially rolled on the body circumference of the reel 21b from one end in the axial direction to the other end, and from the other end to one end, so that the wire material 2 is sequentially wound in a laminated manner. It is being wound up.
Therefore, when winding on this winding reel 21b, the tracking plate 27 and the hook 28
The lower end wire 29 that is locked between the linear object 2
Even if there is a full roll on the same reel, reel 21
It is stably and reliably exposed and maintained on the circumference of the chucking foil 24 at a distance from the circumference of the flange 23 of b, and the lower opening wire 29 can be easily drawn out to a sufficient length, and the Connection and other operations can be made extremely convenient, and conventional problems can be solved.

(Example) An example of the technical means according to the present invention will be described in the first,
Figures 2 and 3 will be explained. 2 take-up reels 2
1a and 21b each consist of a reel body 22 and flanges 23 and 23 that support both ends of the body, and as already described in FIG. It is rotatably and removably attached to the Also, located at one end in the axial direction of each reel 21a, 21b, there is a chucking plate (locking member) 27 and a hook 2 for drawing out the lower line on the outer peripheral side thereof.
A tracking wheel 24 having a number 8 projecting from the circumferential side is disposed so as to be able to stop rotating along with the reels 21a and 21b and to be detachable from the reels. The chucking plate 27 is a plate body bent into a substantially U shape, and one bent end serves as a claw 27a, and the base of the claw 27a has a stepped portion for locking the linear object 2. 27b is formed. Further, the hook 28 for drawing out the lower wire is protruded in an L-shape from the upper end of the bracket 30 as shown in the fourth figure.

The chucking plate 27 cuts the linear object 2 chucked by the claw 27a at the position of the claw 27a.The cutting hammer 26 has both reels 21a and 21b.
Cut portions 26a, 26a are formed on both sides facing the reels 21a, 21b, and numeral 31 in the figure indicates a line shifting lever. In addition, the chucking plate 27 and the hook 2 for drawing out the bottom line
The shape and structure of 8 may be other than those shown in the illustrations as long as the linear object 2 can be securely held between the plate 27 and the hook 28, and the plate 27 is always attached to the hook 28 in the reel rotation direction.
It is assumed to be located further forward than the Further, the mechanism for moving the traverse sheave 25 across the reels 21a and 21b and the reciprocating mechanism for reciprocating in the axial direction of the reel on each reel may be the same as that of a conventional traverse sheave. In addition, a hammer 26 for cutting wire materials and a wire collection lever 31 are installed.
It is possible to use the cutting member and the line gathering lever used in conventional winding machines of this type.

According to this embodiment, it goes without saying that the same movement as previously explained in the section of operation with respect to FIGS. 1 to 4 is performed, and as shown in FIG. When the reel 21a is fully wound, the reel 21a is stopped and the other take-up reel 21b is rotated.
Reel 2
The wire material 2 extending from the full winding side of 1a to the traverse sheave 25 side is hooked onto the pawl 27a of the plate 27 as the line shifting lever 31 is moved, and the reel 21b is stopped at the position shown in FIG.
The traverse sheave 25 is moved to the center position as shown in the second figure, and the sheave 25 is
By moving the wire rearward, the two portions of the linear object extending between the chucking plate 27 and the sheave 25 are moved to a position outside of and directly facing the hook 28 for drawing out the lower wire, and then as shown in the third figure. By returning the traverse sheave 25 to its original position, the two portions of the linear object extending between the tracking plate 27 and the sheave are placed over the hook 28, and the sheave is further moved forward. Accordingly, hook 2
8. Make sure that the two parts of the linear object that have been crossed over the hook 2 are
8 and rotates the take-up reel 21b in the winding direction, the wire 2 extending from the full winding side to the sheave 25 side is moved to the hammer 26 at the claw 27a position of the tracking plate 27. Cut portion 26
a, and the cut end at the claw 27a position is fixed to the tracking plate 27 with the winding start end, and the portion of the wire 2 extending between this winding start end and the hook 28 is connected to the lower end line 29. As such, the wire material 2 is continuously wound on the reel 21b side in a state where it is secured under a sufficient length and exposed outside the periphery of the reel 21b, and in the fully wound state,
Even if the wire 2 from the hook 28 to the reel body is hidden by the fully wound wire, the lower end wire 29 outside the reel periphery remains completely exposed, preventing connection. This means that there will be no problem in other post-processing operations.

(Effects of the Invention) According to the present invention, in the conventional double reel type wire material winding machine of this type, the claw wheels 5, 5' are simply
A claw 1 for capturing and cutting a linear object 2 on the circumferential side of the
2 and 12', it solves the drawback that the lower end wire that becomes the winding start end is left as an extremely short part at the claw part, and is necessary as the lower end wire 29 for joining. Moreover, one having sufficient length can be secured around the outer periphery of the tracking foil 24. Furthermore, in the present invention, a chucking plate 27 and a lower line drawing hook 28 are provided on the circumferential side of the chucking wheel 24, which corresponds to a conventional pawl wheel, at front and rear positions along the reel rotation direction.
At the same time, the linear object 2 is placed on the hook 28 by the movement of the traverse sheave 25 during winding.
As a result, the required length of the lower wire 29 can be easily obtained between the plate 27 and the hook 28, and there is almost no need to make any modifications to the continuous winding and transferring operations. , and can be carried out without causing too much trouble or difficulty in the wire-like material winding operation.
