Description

[Detailed explanation of the invention] This invention uses a shuttle to store the winding material.
The present invention relates to a winding device for winding a winding material around an annular body such as a toroidal core, and particularly to a structure for holding the winding start end of the winding material when the annular body is reciprocated within a required angle range.

A winding device that winds electric wires in the same direction around the core of an annular body is equipped with a shuttle that stores winding material of a required length and a holding device that holds the core.The core is inserted into the shuttle and the core is held in the holding device. After that, rotate the shuttle in a predetermined direction (wire storage direction), wind the required length of winding material around the shuttle, store the wire, pass the end of the wire through the groove of the guide member fixed to the end face of the shuttle, and insert it by hand. After holding the guide member so that it does not slacken and bring the guide member close to the core, rotate the shuttle in the opposite direction to the wire storage direction (winding direction), and use the holding device to rotate the core to the required position around its axis. It is configured to rotate back and forth within an angular range to wind the wire around the core a required number of times.

If there is only one layer of winding on the core and the lead wire is short, there is no need to hold the end of the winding by tying the starting end of the winding to the core, but when the core is small and the winding material is thin, It is difficult to connect the winding start end to the core sufficiently, and when the winding material is thin and the lead wire is long, the winding start end is attached to the holding device,
It is necessary to hold the starting end of the winding to prevent it from getting tangled with the core itself. When winding multiple layers of thin winding material around the core, hold the starting end of the winding material by hand and rotate the core back and forth while applying appropriate tension to prevent slack and breakage. Therefore, it is necessary to move your hands.

As described above, in the case of the conventional toroidal winding machine, a worker must be present at all times to hold the winding start end of the winding material during the winding process. When the number of windings is large and the winding material is thin, worker fatigue is severe and failures due to breakage of the lead wire during winding are inevitable.
Work efficiency will drop significantly.

The purpose of this invention is to easily hold the winding start end of the winding material during toroidal winding work, to prevent wire breakage due to excessive tension on the lead wire, and to reduce worker overwork and improve work efficiency. be.

This invention consists of a shuttle that stores winding material of a required length, a core of an annular body crossed by the shuttle, and a reciprocating rotation of the annular body around its axis in synchronization with the rotation of the shuttle during winding. In a toroidal winding machine, the winding material stored in the shuttle is wound in the same direction around the core while being unwound. A cylindrical body that rotates back and forth in synchronization with the reciprocating rotation of the annular body is provided, and an elastic wire having a locking portion at the tip is planted around the periphery of the cylindrical body to lock the winding start end of the winding material during winding. It is characterized in that it is locked and held in a stop part.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view of the main parts of the winding machine, and although the shuttle 1 has an inlet that can be opened and closed for inserting the annular core 4, it is omitted in the figure. A groove 2 for storing the winding material is formed on the outer peripheral surface of the shuttle 1, and a guide member 3 having a groove for guiding the winding material is fixed on the end surface. Three shafts 5, 5', rotatably supported at predetermined positions;
A belt 6 and shaft 5 that transmit the rotational force of the motor to the shaft 5 to a pulley (not shown) fixed to one end of each of the belts 5"
A belt 7 that transmits the rotational force transmitted to the shafts 5', 5'' to the shafts 5', 5'' is hung, and the other ends of the three shafts 5, 5', 5'' support the inner periphery of the shuttle 1 and are connected to the shafts 5', 5''. A roller 8 that transmits rotational force to the shuttle 1 is fixed. The core 4 is held on three support plates 9, 9', 9'' by rollers 10, 10', 10'' fixed to the upper ends of three shafts that protrude through these, and the core 4 is A part of it will be linked to shuttle 1. Note that the support plate 9' is different from 9, 9'' in that its right end is extended in an angular shape.In synchronization with the rotation of the shuttle 1, the core 4 is reciprocated within a predetermined angle range around its axis. A roller 10' facing the outer peripheral surface of the shuttle 1
A cylindrical body 12 fixed to the upper end of a shaft 11 that protrudes through the extending part 9'' of the support plate 9' is disposed on the outside of the cylindrical body 12, and a locking part 1 is provided at the top end of the cylindrical body 12.
A belt 15 is attached to a pulley (not shown) fixed below the roller 10' and a groove provided in the circumferential direction at the bottom of the cylindrical body 12. are stretched in a figure 8 shape, and the cylindrical body 12 is rotated back and forth in the direction opposite to the rotation direction of the roller 10' and in the same direction as the rotation direction of the core 4.

The work of winding the winding material around the core 4 in the same direction is performed as follows.

Open the introduction port (not shown) of the shuttle 1, insert the core 4 into the shuttle 1, and insert the rollers 10, 10',
10'' and close the inlet, then fix the end of the winding material from the winding material supply container (not shown) to the shuttle 1. Close the wire storage switch and rotate the shuttle 1 in the wire storage direction, for example, clockwise. The winding material is stored in the wire groove 2. When the required length of wire has been stored, the wire storage switch is opened, the winding material is cut at a predetermined position between the shuttle 1 and the supply container, and the end on the shuttle side is (the winding start end of the winding) is passed through the groove of the guide member 3 of the shuttle 1, and while pulling the wire moderately so as not to slacken the wire, the shuttle 1 is moved in the opposite direction of wire storage, that is, in the winding direction, counterclockwise in this example. After rotating the guide member 3 to a position below the core 4, the winding switch is closed and the shuttle 1 is rotated in the winding direction, and the winding material is rotated as shown in FIG. 2a. The winding start end 16 is fixed by wrapping it around the locking part 14 of the elastic wire 13 of the cylindrical body 12 two or three times so as not to slack.The locking part 14 may be formed into an ear shape by wrapping adhesive tape or , by crimping a small lead lump or bending it into a hook shape, the winding start end 16 becomes the wire rod 1.
Just make sure you don't go beyond 3. Winding start end 16
During this winding, the winding material is unwound from the shuttle 1 and wound around the core 4, and at the same time, the core 4 is rotated clockwise to advance the winding to the state shown in FIG. 2b. The diameter and rotational speed of the cylindrical body 12 are such that at the start of winding, the elastic wire 13 is on the side where the guide member 3 of the shuttle 1 is provided, and the winding start portion is on the front side of the shuttle 1 and the roller as shown in FIG. 2b. The elastic wire 13 is similarly selected to be at the farthest point in front of the shuttle 1 when it comes to the 10' side. In addition, the elastic wire 13
The length of the winding start end 1 in the state shown in Figure 2b
The tension portion 6 is selected so that it does not touch the peripheral edge of the roller 10'. When the winding progresses further and the rotation of the core 4 exceeds approximately 180 degrees, the elastic wire 13 faces the opposite side of the guide member 3 of the shuttle 1, as shown in FIG. 2c. When the core 4 reaches the set rotation angle, the rollers 10, 10', 10'' rotate in the opposite direction, the core 4 rotates in the opposite direction (counterclockwise), and the second layer of winding begins. The core 4 is rotated forward and backward within such a set angle range until the winding machine automatically stops.The winding start end 1
During winding, the elastic wire rod 13 makes a reciprocating oscillating motion and is held under tension with a substantially constant tension, thereby preventing wire breakage at the winding start end 16. Further, since the winding work is almost automatically carried out from the beginning to the end of winding, work efficiency can be significantly improved.

When the winding is completed, return the switch to its original position, open the inlet of the shuttle 1, pull out the core 4 from the shuttle 1, remove the winding start end 16 from the elastic wire 13, and remove the winding end from the shuttle to form one toroidal coil. is completed.
