Abstract

PURPOSE:To facilitate the correction of a coil which has many number of poles and high space factor by telescopically mounting a pair of pawls on a former of a flier type winding machine. CONSTITUTION:A pair of grooves 1b are formed on the end of a cavity 1a formed in a former body 1, and a pair of pawls 2 are slidably mounted respectively in the grooves. A base 2a integrated with the pawl 2 is coupled to a shaft 6 which slides perpendicularly to the sliding direction of the pawl 2 via a pin 3, a link 4 and a pin 5, the shaft 6 is slided in a direction of an arrow Y, and the pawl 2 is telescoped in a direction of an arrow X. A guide plate 8 is provided at the end between the pawls 2, introduced into the slot of a rotor R, and a winding W is guided into the slot. The pawl 2 is moved forward during winding to cooperate with the plate 8 to guide the winding W. When the winding in the slot is finished, the pawl 2 is moved backward, the entire former is then separated from the rotor R, and moved to the winding position of next phase. In this manner, a margin is produced in the winding W to facilitate the correction of the coil having high space factor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire guide device for a flyer one-way winding machine.

A winding machine for winding wire around an electric motor rotor includes a wire guiding device or former, and a conventional former includes a first
With the typical shape shown in the figure, when winding, the former F
contacts the winding phase portion of the rotor R and guides the wire W. This former uses only the shape of the former to wind the wires in a predetermined position, so the number of poles per rotor is small, the space factor is low, and the rotor can be wound without straightening each phase winding. However, especially in cases where the number of poles is large and the space factor is high, such as in a small rotor, winding cannot be performed unless the winding of each phase is corrected. In this case, even if you try to correct this with a conventional former, the coils will tightly wrap around the rotor, making it impossible to correct the problem.When winding the next phase, the previous phase coil will get in the way, making it impossible to wind the next phase. there were.

This invention has been made in view of the above, and aims to provide a wire guide device that eliminates the problems of the conventional ones.In order to achieve this object, a former is provided with l pairs of claws, and 4! It has a structure that allows it to be taken in and out of the rotor! [This is the case.] This invention is particularly effective as a wire guide mechanism for flyer one-way winding machines that have a large number of poles, a high space factor, and require correction.

The invention will now be described in detail with reference to the illustrated embodiments.

As shown in FIGS. 2 and 3, the former body l is provided with a cavity /a, and at the end of the cavity /a there are l pairs of grooves /b. The claw is slidably mounted. The integral base of the pawl λ, 2a, is connected to one end of the link μ by a pin 3 in the cavity /a, and the other end of the link μ is slidable by the pin S in a direction approximately perpendicular to the sliding direction of the pawl. It is pivotably mounted on a sliding shaft mounted on the body. The l pair of claws are thus connected to the shaft 6 by a link mechanism, and can be moved in and out of the body l by pushing the sliding shaft 6 from the outside. For this reason, the body l at the end of the shaft
has holes on both sides. The pressure on both sides of the upper and lower sides of the former body L is balanced by installing the former guide 7 so that the wire is correctly guided on the sliding claw a of the body during winding, and the upper guide is lighter than the lower guide. This is a trap for Forma to always maintain the correct posture. A guide plate g is attached to the tip of the former body l between the claws, and the guide plate g can fit into the slot of the rotor.

When winding is to be carried out, the former body L is supported by the former shaft D as shown in FIG. 4, and the former is set relative to one rotor R as shown, and then the winding is started. During winding, the claws protrude from the body and are located on both the upper and lower sides of the single rotor.

Although the claws protrude, the sliding shaft 6 is housed within the former body 1 (Fig. 2), so it does not get in the way. Information board g
By entering and guiding the wire W into the slot of the rotor R, the wire W applies winding tension on the former during winding, thereby preventing the former from moving relative to the rotor and causing one position shift.

FIG. 4 shows a state in which one phase winding of the wire W has been completed, and the winding is performed in the slot via the upper and lower claws. When winding is completed, if the former and the pawl are moved away from the rotor at the same time, the wire placed inside the slot will tend to protrude out of the slot together with the pawl due to the frictional resistance of the pawl, as shown in Figure 3. When winding is completed, the claw is first pulled into the former body l using an external force using a link mechanism.

At this time, even if the wire W tries to come out of the slot, it will be blocked by the former body l and will not come out. Next, as shown in FIG. 6, by moving the entire former away from the rotor, it can be moved to the primary phase winding position.

When the pawls are drawn into the former body l, the pawls retreat from both sides of the rotor, so that a space corresponding to the shape of the pawls 2 is created above and below the rotor, as shown in FIGS. 3 and 6. This space provides the wire with the flexibility and degree of freedom necessary for correction, allowing it to be freely and easily corrected from the outside.

In this way, the winding of the next phase can be continued after straightening without damaging the wire.

As described above, the present invention has the effect that even when the number of poles is large and the space factor is high, especially in a small rotor, correction can be made freely and easily, and the primary phase winding is not obstructed or trapped. It will be done. The structure is extremely simple, as it only requires a claw on the former body to allow it to be taken in and out.
