Description

[Detailed description of the invention] (Industrial application field) The present invention is based on the traverse (reciprocating) winding of a winding machine that winds a winding material B such as metal wire or thread onto a winding bobbin A, as shown in Fig. 10, for example. (lateral movement) device.

(Prior Art) There have been various types of traverse devices, one of which is shown in FIG.

This is a traverse body E that can freely move back and forth along guides C and D, and guide wheels I and J are attached via a support F and an arm G, and a winding material B is wound around the guides I and J. When the winding bobbin A is fixed to the winding bobbin A and the winding bobbin A is rotated in the direction of the arrow a in Fig. 10A, the winding material B is wound onto the bobbin A. Taking Fig. 10B as an example, when the pressing ring attached to the lever O of the main body E presses against the left stopper M by moving toward the arrow c side, the lever O is moved to the side shown in Fig. 11B. At the same time, the traverse main body E in FIG. 10B turns in the direction of arrow b in FIG. 10B. Traverse body E
When the lever O continues to move to the left side and the pressing ring K presses against the left stopper L shown in Fig. 10B, the lever O is reversed to a direction symmetrical to that shown in Fig. 11A to E, and the traverse body is E turns in the direction of arrow c in Figure 10 (b) and returns in the same direction. By repeating this, the traverse body E reciprocates in the lateral direction.

As a result, the guide bodies I and J in Fig. 10 attached to the traverse body E are
The winding material B, which is guided by the guide bodies I and J, is swung in the longitudinal direction of the winding bobbin A and wound in the entire longitudinal direction of the bobbin A, as shown in FIG. 14A and B.

(Problems with the Prior Art) In the conventional traverse device, the traverse speed is constant and the position at which the traverse body E turns is always the same, so the following problems occurred.

(1) If the winding speed of the winding bobbin A is kept constant and the moving speed of the traverse body E is increased, the first
As shown in Figure 4, the angle (delay angle) between the traversing guides I and J and the winding position increases, and when the traverse body E turns, the winding continues until the delay angle becomes reversed as shown in Figure 14B. The turn on the winning side is delayed. As a result, as shown in Fig. 12, both ends of the winding bobbin A in the longitudinal direction become thick, and the winding material B at both ends collapses, or when the winding material B is pulled out from the winding bobbin A. There were cases where wires B got tangled and broke.

(2) If the amount of the winding material B, especially the outer diameter (the outer diameter when winding is completed) is kept constant, and the thickness of the winding material B is made thinner or thinner, both ends of the winding bobbin A The amount of curling and thickening is accumulated, and both ends become thickened. As a result, there is a problem similar to that in case 1 above.

(3) A ribbon phenomenon as shown in Figure 13 appears. This ribbon phenomenon is a phenomenon that occurs when the winding pitches of the winding material 2 overlap in the relationship between the winding pitch and the winding diameter, and it occurs at a certain diameter,
If it exceeds that diameter, it will disappear. For this reason, when the wound material B is pulled out, the winding collapses, making it difficult to pull out, and making the winding material B more likely to break.

(4) In order to eliminate the thick winding at both ends of the winding bobbin, a method has been considered to turn the traverse body E early.
As shown in Figure 5, both ends of the winding bobbin A are recessed, so if the winding material B is a metal wire, the metal wire that has been carefully wound will slip into the recess X and collapse, causing the winding to collapse when being pulled out. The metal wires may get tangled and become difficult to pull out, or may break.

(Purpose of the invention) An object of the invention is to realize a traverse device that prevents the winding from becoming thick at both ends of the winding drum and prevents the ribbon phenomenon from occurring.

(Means for Solving the Problems) The traverse device of the present invention has a guide body (for example, shown in FIG. 10) that guides a winding material B such as a wire rod to a traverse main body that moves back and forth (for example, E in FIG. 10). I, J) and lever 3 are attached, a pusher 4 is attached to the lever 3, the pusher 4 is attached to the lever 3, and the pusher 4 is pressed against the stopper 5 by the movement of the traverse body. In a traverse device in which the direction of the lever 3 is then reversed and the traverse body turns and moves to the opposite side, the pusher body 4 is attached to the lever 3 eccentrically and rotatably. is pressed against the stopper 5 so that the turning position changes each time the traverse body turns.

(Operation of the invention) FIGS. 1 to 8 are explanatory views of the operation of the traverse device of the invention. In these figures lever 3
is wound around the traverse body (for example, E in FIG. 10), and traverses together with the traverse body E.

The lever 3 in Figure 2A moves to the right, and the pusher 4 hits the stopper 5 as shown in Figure 2B.
When it moves further to the right, the groove formed on the outer circumferential surface of the pressing body 4 engages with the groove of the stopper 5 as shown in FIG. If the lever 3 continues to move toward the stopper 5 in this state, the lever 3 will be raised by the stopper 5 as shown in Figure 2C, and will be about to be reversed. Turn.

Moreover, since the pushing body 4 is eccentrically attached to the lever 3, the state immediately before reversal changes each time as shown in FIGS. 3A to 3C. Incidentally, the maximum amount of change is approximately twice the amount of eccentricity, as shown in Figure 6 (c). Therefore, as shown in FIG. 5, the reversing position of the lever 3 changes each time it is reversed, and as shown in FIG. 6, the turning position of the traverse body also changes each time it turns. Therefore, the winding material B wound on the winding bobbin A is
Do not roll it at both ends.

The above explanation is based on the case where there is only one pressing body 4, and the pressing body 4 is pressed against the stoppers 5 on both the left and right sides. In this case, if the structures of the left and right stoppers 5 are the same, even if the pushing body 4 presses against one stopper and rotates, when it presses against the other stopper, it will be returned by the amount of rotation, and the traverse body E The inversion position of will always be constant. For this reason, when there is only one pusher 4, it is necessary to make the amount of rotation different when the pusher 4 hits one stopper and when it hits the other stopper. To do this, for example, as shown in Fig. 7, the spacing and number of grooves 8 and 9 on the left and right rotations 5a and 5b may be made different, or the angle at which the lever 3 is raised by pressing against the stopper 5 may be adjusted. or change it.

FIG. 8 shows another example of the traverse device of the present invention. This is a lever 3 in which two pressing bodies 4a and 4b are attached eccentrically to each other. In this case, the left pressing body 4a presses against the left stopper 5a, and the right pressing body 4b presses against the right stopper 5b. Pushing body 4a,
When the pushers 4b are pressed against the stoppers 5a, 5b, the rotational state of the pushers 4a, 4b is the same as when there is only one pusher. In this case, the left pusher 4a is pressed against the left stopper 5a, and the right pusher 4b is pressed against the left stopper 5a.
Since the right stopper 5b is pressed against the right stopper 5b, even if the left and right stoppers 5a and 5b have the same structure, the problem that occurs when there is only one pressing member does not occur.

(Example of the invention) In Fig. 5, the pressing bodies 4a, 4b and the stopper 5
Although grooves are formed in both a and 5b, it is also possible, for example, to form grooves only in one of the pressing members and the stopper, and not to form grooves in the other. In this way, since the positions of the left and right turns of the traverse body are different, the positions of the turns of the winding material B are also different each time the winding material B is turned, as shown in Fig. 9, and thickening of the winding at both ends of the winding bobbin is prevented. . Incidentally, in this case, the width of the traverse of the traverse body is constant, but the position of the turn shifts from side to side.

Further, the pressing body 4 may be a roller or the like instead of a gear.

The abutment surface of the stopper 5 is not easy to press, and may be made smooth or, conversely, formed with a non-slip surface. In short, the pressing body 4 and the left and right stoppers 5a,
5b may be any type as long as the amount of rotation of the pressing body 4 that presses against it changes.

(Effect of the invention) The traverse device of the invention has the pushing bodies 4, 4a,
4b is eccentrically and rotatably attached to the lever 3, so that the pushing bodies 4, 4a, 4b
The amount of rotation changes each time it presses against the stopper 5, 5a, 5b. Therefore, the position of the turn of the traverse body changes each time it is turned, and furthermore, the position where the winding bobbin A is wound at both ends changes each time, so that thick winding at both ends is eliminated. Further, no ribbon phenomenon occurs.
