Description

  The present invention relates to a winding device for a linear body such as an electric cable.

  A linear body winding device of this type is generally described with reference to FIG. 1 showing an embodiment of the invention according to the present application. A drum that rotates around an axis and winds a linear body a 10, a guide 27 that guides the linear body a toward the peripheral surface of the drum 10, a traverser 20 that reciprocates the guide 27 between the flanges 11 a and 11 b at both ends of the drum 10, and the linear body and a control means for controlling the movement of the traverser 20 so that a is wound in a multilayered manner on the peripheral surface of the drum 10 (Patent Document 1, Claims, FIG. 1, Patent Document) 2. See claims and FIG.

  For example, as shown in the figure, the linear body winding device is configured to rotate the drum 10 by rotating the drum 10 after stopping the tip end a ′ of the linear body a on one of the flanges 11b (see the broken line portion). The linear body a is wound around the body portion in the axial direction. At this time, the linear body a is wound around the tip a 'at an angle to the direction perpendicular to the axis of the drum 10 (radial direction). Further, as shown in FIG. 9A, after the final winding of the linear body a is wound at a position that is 1/2 pitch (cross-sectional radius of the linear body a) t from the flange 11a (on the flange 11a side). After the winding end reaches the end of the wire, it is wound in the direction of the other flange 11b (see Patent Document 1, column 7, lines 25-30). For this reason, as shown in FIG. 9 (b), in the folding at the flange 11a, after being wound in a state where it is placed between the final winding and the flange 11a, the winding 11 is directed to the groove s between the windings in the direction of the flange 11b. It is wound (fitted) along.

At this time, as shown in FIG. 9 (c), up linear body a ₂ of the first winding of the second layer is riding on a linear body a which rests during the final winding and the flange 11a of the first layer It may be rolled up. In this case, falls into the groove s between the linear body a linear body a of the next to linear body a ₂ went up the ride is adjacent to the flange 11a, then the second layer along the grooves s is It may be wound, but as indicated by a chain line in the figure, it may jump over the groove s and fall into the previous groove s, and the winding may be continued. If it becomes like this, the space for one volume will arise between the 2nd layer 1st volume and the 2nd volume. This space may cause collapse in the vicinity of the ridge 11a after the third layer. The space may be generated not only in the second layer but also in the third and subsequent layers, in the vicinity of both sides 11a and 11b of each layer, and there is a risk that the collapse will occur each time.

For this reason, as one means for eliminating the collapse, there is one in which the linear body a is wound around the drum while being fed with a delayed feed angle (see θ in FIG. 1) (Patent Document 1, column 8, column 8). 41 to 9th column 2nd line, see FIG. 6).
Further, as another means, the length direction of the drum 10 around which the linear body a is wound is divided at the central portion, and the linear body is arranged on the drum 10 from one flange portion (one end portion) to the central portion of the drum. a is wound while being supplied with a delay angle (delay feed angle), and is wound while being supplied with the same advance angle (advance feed angle) from the central portion to the other flange portion (the other end portion). (See Patent Document 2, Claim 1, FIGS. 3 to 11, etc.).

  Although each of the above prior arts is effective as it is, the folding may occur when the collar is folded back. Also, depending on the state of the linear body (thickness, number of twists, flexibility, etc.), the linear body If the traverse position, the folding distance, etc. are not finely adjusted, there will be a problem that the roll will collapse and the adjustment is complicated.

  This invention makes it a subject to reduce the collapse | fold collapse at the time of the folding | turning in a collar part as much as possible under the above actual condition.

  In order to achieve the above object, the present invention provides a drum that rotates around a shaft and winds a linear body, a guide that guides the linear body toward the peripheral surface of the drum, and a guide for the drum. In a linear body winding apparatus, comprising: a traverser that reciprocates between the ends of the both ends; and a control unit that controls movement of the traverser so that the linear body is wound in a multilayered manner on a peripheral surface of a drum. The control means is configured to move the linear body when the linear body moves toward one side of the drum and the winding tip reaches the end of the side of the drum and folds back toward the other side. When the winding tip reaches the end on the side, the required length is folded back, returned again to the end of the one side, and then moved toward the end of the other side, and the same applies to the other side of the side. Fold back, return, and move toward the edge of the ridge, and then perform the same action. As Te finish winding is to that configured to control the traverser.

  Normally, in the traverse movement in the opposite direction in the folding at the heel part, if the folding distance is small, the winding layer collapses at the winding layer end, and conversely if the distance is large, the winding layer end There is a possibility that a space that is far away from the part occurs and a space for the one turn is generated. For this reason, as the above-described configuration, once it is folded back largely to prevent lap winding (a linear body that is prevented from being wound on the above-mentioned linear body a that has ridden and formed into a multi-layer is formed. a) shift to the next groove), and then return to the opposite direction (side) to stabilize the fitting into the next groove, and even if overcoming the next groove Swing it back into the adjacent groove and fit it.

At this time, if the traverser is stopped between the folding action and the returning action, the linear body is shaken off by the folding action to ensure the falling time, and the linear body is wound on the lower layer. It can be surely depressed and fitted between the linear members of the layer. The traverser's stop action time is preferably set by the rotation angle of the drum so that it is not affected by the speed of feeding (feeding) the linear body to the drum.
Moreover, it is preferable that the folding action and the returning action of the traverser be performed while the drum is rotated once after detecting that the winding end has reached the end on the heel side. FIG 9 riding linear body a ₂ shown by (c), interlace is because the drum after the detection of the winding ends often may occur during one rotation.

  The above folding distance, folding operation speed, stop time, return distance, and return operation speed are based on the state of the linear body (thickness, number of twists, flexibility, etc.) and the state of the wrinkles (material, etc.) Set as appropriate. For this reason, the folding distance or the like can be set independently.

In addition, each of the traverser's forward path and return path can be divided into at least three zones. This section can be used in combination with the above configuration.
That is, first, in winding the linear body around the drum, since the optimal winding conditions are different between the end flange portions and the other portions (portions between both ends), the traverse length is set to at least three zones. If it divides into two, optimal winding can be performed by setting the winding conditions of the both ends collar part and other parts separately. Zones can be divided into four or more round trips.

Next, in the forward path and the return path, the traverse direction is also reversed, and when the linear body is a stranded wire, the twist direction with respect to the traverse direction is also reversed. It was a partition area. That is, in the following embodiments, the section widths of (i) and (iv), (ii) and (v), (iii) and (vi) are also different, and the traverse moving speed and drum axis of the section area are different. The winding conditions such as the feeding angle θ of the linear body with respect to are also made different.
At this time, usually, if the feed angle θ is taken as a large delay angle, the winding end smoothly proceeds and the winding state is stabilized. However, if the delayed feed angle θ is large in the vicinity of the heel, the force separating from the heel is increased. It works on a linear body and it is difficult to wind it close to the edge of the bag. For this reason, it is assumed that the feed angle θ with respect to the perpendicular line to the axis of the drum of the linear body from the traverser to the drum in each zone of the forward path and the backward path is sequentially reduced toward the traveling direction as a delay angle. You can wrap it around the edge of the kite. Reducing the delayed delivery angle θ includes the case where the delivery angle θ is changed from the delay angle to the advance angle (see Example 3 in Table 3 below).

  Since the present invention is configured as described above, it is possible to effectively prevent the collapse, and in particular, to effectively prevent the collapse at the collar portion (end portion).

One embodiment of the linear body winding device according to the present invention is shown in FIGS. 1 to 8, and the linear body winding device A of this embodiment is a core of an electric wire cable fed from a twisting machine 7. This Z (S) stranded copper wire a is wound around a drum 10 as shown in FIG. For this reason, the copper wire a is fed into the drum 10 at the delivery speed v determined by the rotational speed of the twisting machine.
The drum 10 has flanges 11a and 11b (general symbol: 11) on both sides, and is rotated around the axis 12 by a driving machine (not shown). The rotation is fixed so that the tension of the copper wire a is constant. Tension controlled. For this reason, if the winding diameter of the copper wire a becomes large, the rotation speed of a drum will reduce.
A rotary encoder 14 is attached to the drum 10, and the rotational speed and rotational angle (rotational displacement) of the drum 10 are calculated by a controller (not shown) based on the detected value of the rotary encoder 14 (patent) Reference 2 paragraphs 0037 and 0040, FIG. 1 etc.).

The drum 10 is provided with a traverser 20, and a base plate 21 of the traverser 20 is movably provided on a screw shaft 22 and a guide shaft 23 (see Patent Document 1, FIG. 1 and the like), and a screw. The shaft 22 reciprocates in the direction of the arrow as shown. The screw shaft 22 is connected to a drive unit 24 and rotates at a required speed to reciprocate the traverser 20 at a required speed at a required speed.
Further, a rotary encoder 25 is attached to the drive unit 24, and the rotational speed of the screw shaft 22, that is, the position of the traverser 20 is detected based on the rotational displacement of the rotary encoder 25 (paragraph 0037 of Patent Document 2). , 0040, FIG. 1 etc.).

In this embodiment, the position of the traverser 20 is set so that the reference point o is also located in the drum width of the drum 10 that can be set in the linear body winding device A. Therefore, for example, in FIG. 1, if the rotational displacement number of the rotary encoder 25 at the reference point o is 1000, the position of the right flange 11b is less than 1000, for example, the rotational displacement number is 950, and the left side The position of the heel 11a is detected with more than 1000, for example, the number of rotational displacements: 1785. Further, when the traverser 20 passes the reference point o, the error with respect to the reference point position of the traverser 20 is corrected by the detected value.
Instead of the rotary encoders 14 and 25, a pulse motor or the like may be used as a drive machine, and the rotation speed and rotation speed of the drum 10 and the screw shaft 22 may be calculated based on the rotation speed and rotation speed of the drive machine 24. .

  On the base plate 21 of the traverser 20, a swing plate 26 is swingably provided with a support shaft c, and guide rollers 27 and 27 are provided on the front and rear (up and down in FIG. 1) of the swing plate 26. Yes. When the stranded copper wire a guided by the guide rollers 27 is inclined with respect to the axis of the drum 10, the swing plate 26 is also inclined as shown by the arrow in accordance with the inclination. The feeding angle θ of the copper wire (linear body) a fed from the guide roller 27 with respect to the direction perpendicular to the axis 12 of the drum 10 is determined according to the swing angle. This feed angle θ is measured by the sensor 28 on the base plate 21 and sent to the controller. The sensor 28 employs a proximity sensor or the like, measures the distance to the copper wire a, and calculates the feed angle θ according to the distance. The sensor 28 may be replaced with an angle sensor that detects the swing angle of the swing plate 26 (see Patent Document 2, paragraph 0040, FIG. 1).

In the linear body winding device A, the current position of the traverser 20 is the tip of the winding layer, and the current position of the traverser 20 is the rotational speed (rotational displacement) of the screw shaft 22 by the rotary encoder 25 of the screw shaft 22. ) To detect.
Depending on the current position of the traverser 20, the movement area of the traverser 20 in the drum 10 is demarcated. If the movement from right to left in FIG. 1 is the forward path, the forward path is (i), (ii), (iii). Similarly, the return path is divided into three zones (iv), (v), and (vi). The length (width) of each of the zones (i) to (vi) is set so that proper winding is performed in consideration of the winding length of the drum 10 (the distance between both ends), the state of the copper wire a, and the like. It is set appropriately for experiments.

  In which zone the traverser 20 is located, the controller determines which zone (i) to (vi) the current position of the detected traverser 20 is in, and each zone (i) , (Ii), (iii) or (iv), (v), (vi), the feed angle (winding angle) θ is determined. The feed angle θ can be set separately. In this embodiment, the outgoing angle θ in each zone (i), (ii), (iii), (iv), (v), (vi) of the forward path and the backward path is set as a delay angle toward the traveling direction. It is getting smaller one after another. For example, the zones (i) and (iv) are θ: 1.10 degrees, the zones (ii) and (v) are θ: 0.7 degrees, and the zones (iii) and (vi) are θ: 0.2 degrees. To do.

  Further, the final winding (winding layer tip) of the copper wire a is wound around the end of the drum 10 on the side of the flanges 11a and 11b, as shown in FIG. After that, when winding in the state of being placed between the final winding and the collar 11a shown in FIG. 9B, the feed angle θ gradually decreases and falls within a certain change. It is detected that the front end of the layer has reached the end of the drum. At this time, the rotation angle α of the drum 10 that falls within a certain change is, for example, 30 degrees or more, and the position detection value of the traverser 20 is also used as a determination factor for the determination at that time. As described above, assuming that the position detection value of the traverser 20 is also a determination factor, for example, in the zones (i) and (iv) other than the ends of the flanges 11a and 11b, the constant rotation angle α (for example, 30 degrees) of the drum 10 Even in the above case, if the feed angle θ is 1.10 degrees or less and the feed angle θ is 0.7 degrees or less in the zones (ii) and (v), there is some trouble in winding the copper wire a. I understand that.

  Further, in this linear body winding device A, the copper wire a moves (in the forward direction) toward one flange 11a (for example, the left side in FIG. 1) of the drum 10, and the end on the one flange 11a side. When the winding tip reaches the end, the required length is folded back and returned again to the direction of the one hook 11a, and then moved toward the other hook 11b. The traverser 20 is controlled so as to turn back, return, and move in the direction of the single hook 11a, and thereafter perform the same action and finish the winding.

  That is, first, as shown in FIG. 5A, the copper wire a drawn out from the traverser 20 is fixed to one end of the drum 10 (inside the flange 11b) in the same manner as in the prior art, as shown in FIG. When the winding is started, it is determined that the condition setting is completed, and if it is completed, the operation start button is pushed based on the display to that effect. The drum 10 is rotated by this operation, and it is recognized that the winding is in the zone (i) from the initial position of the traverser 20 (for example, the rotational displacement number of the rotary encoder 25: 900), and the feed angle θ is θ1. The movement of the traverser 20 is controlled so as to be (= eg, 1.10 degrees), and the copper wire a is wound around the drum 10 (FIG. 5B).

  When the winding operation continues and the position of the traverser 20 (winding tip) reaches the zone (ii) (that the traverser 20 has reached this zone (ii), the rotary encoder 25 attached to the screw shaft 22 Detection is based on rotational displacement (the same applies hereinafter) The copper wire a is wound around the drum 10 by controlling the movement of the traverser 20 so that the feed angle θ is θ2 (= 0.7 degrees, for example) (FIG. 5). (C)) Further, when the winding tip reaches the zone (iii), the movement of the traverser 20 is controlled so that the feed angle θ becomes θ3 (= 0.2 degrees, for example), and the copper wire a is drummed. 10 (FIG. 5 (d)).

Eventually, when the winding tip reaches the inner side surface (left end of the drum 10) of the flange 11a ((1) in FIG. 2), the operation shifts to the operation shown in FIGS. 3 and 6, and first, as shown in FIG. 6 (a). As described above, after the final winding of the copper wire a is wound at a position separated from the flange 11a by 1/2 pitch (cross-sectional radius of the copper wire a) t (see FIG. 9A), the final winding and the flange 11a. (See FIG. 9B). When this winding is performed, since the feed angle θ from the traverser 20 becomes 0.2 degrees or less, the controller determines that the winding tip has reached the hook 11a, and moves the traverser 20 in the direction of the other hook 11b. Transition to the turning action toward.
When the folding is performed for a required length, it stops (FIG. 6 (b)), and again returns to the direction of the one ridge 11a (from FIG. 6 (b) to (c)), and thereafter, FIG. 6 (d), As shown in FIG. 7, it moves toward the end of the other ridge 11b. At this time, it is preferable that the folding distance ≧ the returning distance.

  In this folding operation, even if the end of the drum 10 is wound in multiple layers (overlapping) as shown in FIG. 9 (c), the copper wire a wound in the multilayer is swung. As shown in FIG. 9B, it is inserted into the groove s with the adjacent copper wire a. At this time, if the turn-back distance is short, they are superimposed, and conversely if they are long, they are jumped by one turn (see FIG. 9C). For this reason, the folding length is appropriately set by experiments or the like so that such inconvenience does not occur. After the folding action, the traverser 20 is stopped by the operation to be surely shaken down, and is surely dropped into the groove s between the copper wires a of the lower winding layer.

  Furthermore, even if the copper wire a protrudes from the inside of the groove s with the adjacent copper wire a by the folding action (see the chain line state in FIG. 9C), the returning action in the direction of the one flange 11a. Thus, the winding tip is brought close to the flange 11a side and fits in the groove with the adjacent copper wire a (see FIG. 9B), and the winding layer neatly arranges the copper wire a (alignment). State). For this reason, at the time of the movement toward the end of the other ridge 11b, it is further wound from the front end side of the beautiful winding layer.

After the above folding and returning action, when the traverser 20 moves in the direction of the other saddle 11b, it recognizes that the winding is in the zone (iv) as shown in FIG. 3 and FIG. The copper wire a is wound around the drum 10 by controlling the movement of the traverser 20 so that the angle θ becomes θ4 (= 1,10 degrees, for example) (FIG. 7A).
When the winding action continues and the winding tip reaches the zone (v), the movement of the traverser 20 is controlled so that the feed angle θ becomes θ5 (= 0.7 degrees, for example), and the copper wire a is drummed. 10 (FIG. 7B). Further, when the winding tip reaches the zone (vi), the movement of the traverser 20 is controlled to wind the copper wire a around the drum 10 so that the feed angle θ becomes θ6 (= 0.2 degrees, for example). (FIG. 7 (c)).

Eventually, as shown in FIG. 8 (a), when the winding tip reaches the inner side surface (the right end of the drum 10) of the flange 11b (when the end is detected ((2) in FIG. 3)), it is shown in FIGS. In the same manner as the winding at the end on the side of the flange 11a, first, the required length is folded back and stopped (FIG. 8B), and then returned to the direction of the other flange 11b again (FIG. 8C )), And then, it moves toward the direction of one ridge 11a (FIG. 8 (d)).
At this time, similarly to the above, by this folding action, even if the end of the drum 10 is wound in a multilayer, the copper wire a wound in the multilayer is shaken off, and the adjacent copper wire a It fits into the groove s. Similarly, after this folding action, the traverser 20 is stopped by the operation of stopping the traverser 20 and is surely dropped and fitted between the copper wires a of the lower winding layer.

  Furthermore, even if the copper wire a protrudes from the inside of the groove with the adjacent copper wire a by the folding action, the winding tip is moved toward the hook 11b side by the returning action in the direction of the other hook 11b. Then, it fits into the groove with the adjacent copper wire a, and the winding layer is in a state where the copper wire a is neatly arranged. For this reason, at the time of the movement toward the direction of the one ridge 11a, it will be further wound from the front end side of the beautiful winding layer.

  Thereafter, the operations of FIGS. 2 to 4 and FIGS. 5 to 8 are repeated ((3) of FIG. 4), and when the winding of the copper wire a around the drum 10 is completed (the winding length is predetermined). If the required number of winding layers is reached, (4) in FIGS. 3 and 4), the rotation of the drum 10 is stopped, and the operation of cutting the copper wire a and setting the next drum 10 is started. When the drum 10 is reset, the above actions are performed, and the copper wire a is wound around the drum 10.

The above folding, stopping and returning operations are preferably performed while the drum 10 makes one rotation after detecting the hooks 11a and 11b (after determining that the winding tip has reached the hooks 11a and 11b). .
Further, when the winding tip (frontmost winding of the copper wire a) reaches the inner surface (end of the drum 10) of the other rod 11 from the one rod 11, the traverser 20 is on the vertical line (radial direction) of the rod 11. ) And the copper wire a can jump out from the outer peripheral edge of the flange 11 (see Patent Document 1 FIG. 6 (D)). The distance over which the traverser 20 exceeds is appropriately set by experiments or the like so that smooth winding is performed at the end of the winding layer.

In the linear body winding device A of the above-described embodiment, the above-described stranded copper wire a (Examples 1 to 6) of the types shown in Table 1 is fed out to the drum 10 having a body diameter and a body width shown in the same table. When the action in each zone (section) (i) to (vi) shown in Table 2 is performed according to the speed v, the folding operation, the stopping operation, the returning operation, and Table 3 are performed. The copper wire (linear body) a could be smoothly wound around the drum 10.
In Table 1, “H” is hard copper, “A” is soft copper, “SB” is a twisted copper wire that is tightened after twisting the copper wire, and “circle” is a twisted copper wire ( (SQ) indicates the cross-sectional area of the stranded copper wire after being twisted. In Table 2, the angle α at the time of the stop operation is “stop of the traverser 20 after the turn-back operation” The rotation angle of the drum 10 is “hour”. In Table 3, “delay” in “direction” is when the traverser 20 is located rearward from the winding front end in the winding direction (see FIG. 1). “Advance” is when the traverser 20 is located in front of the winding front end.

Although the said embodiment was the case of the stranded copper wire a, it cannot be overemphasized that this invention can be employ | adopted as a winding device of various linear bodies, such as a resin-coated cable.
Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
