Description

[Detailed Description of the Invention] This invention relates to a device that automatically removes only a coil from an integrally constructed coil winding jig.

A coil winding jig or member has a large number of coils wound at a constant number of turns using a special coil winding device, but when removing just the coil from this coil winding member, the coils may become tangled or There are some troubles such as the coil unraveling.

This invention aims to provide a device that can smoothly remove a coil from a coil winding member, with the above points in mind.

Hereinafter, this invention will be explained based on the accompanying drawings showing examples thereof.

Reference numeral 1 designates a base. As shown in FIGS. 1 and 2, a large number of frame groups 3 are mounted on the base, which can be slid via horizontal guide bars 21.2b. arranged in parallel.

A stopper member 4 is provided between each frame 3 to prevent the gap from opening more than a certain width, and a rod 6 of an air cylinder 5 is fixed to the front frame. 5, each frame 3 is moved in a parallel direction to open and close between each frame.

As shown in FIG. 4, the frame 3 is made up of opposing vertical arms 3a, 3a integrated at the bottom via a support plate 3b. A groove 7 is formed.

A claw 9 is provided on the front surface of the support plate 3b and extends upward between the arms 3a, 3a, and the upper surface of the claw 9 from the thin rod-shaped tip 9a to the most part forms an inclined surface 8 that descends toward the rear. .

One end of the stopper member 4 is bent into a hook shape to prevent the spaces between the frames from expanding any further when a certain distance is created between the frames by pulling the rod 6 from the closed state between the frames 3. The bent portion 4a is configured to be locked to a protrusion 4b of the next frame.

For example, the overhanging structure may be such that the frames are connected by a link member having an elongated hole, and a protrusion of the next frame is latched into the elongated hole.

The bobbin 10 serving as a coil winding member is shown in FIG. 3.

As shown in FIG. 5, the coil winding part 12 with an inclined explosive surface and the flange 10a on the edge of the end face are separated from each other, and both sides of the flange 10a are fitted into the groove 7 from above as shown in FIG. Frame 3
The bobbin 10 is supported.

As shown in both figures, a hole 17 into which the tip of the clip 15 is inserted is formed on the outer circumferential surface of the winding portion 12, so that the wound coil 14 can be easily held by the clip 15.

Further, a hole 18 extending from the winding part 12 to the collar 10a is formed on the outer surface of the bobbin 10, and when each frame 3 is closed as shown in FIG. It is located at the collar portion of the hole 18.

Furthermore, the center of the bobbin 10 is a through hole 11, and this through hole 11 is open at the top.

A large number of bobbins 10 are connected by arbitrary connecting rods (as shown) to form one unit, and the coil 14 is wound around each of the winding portions 12 in the unit state.

Since the wound coil 14 is sandwiched between the collars 10a on both sides, it will not come off or become tangled.

Thus, the coil bobbin 1 with the coil 14 wound thereon
0 with the frame 3 closed, each tsuba 10
a is fitted into the groove 7 of each frame 3.

Before installation, each coil 14 is temporarily secured at its lower end with a clip 15, as shown in FIGS. 5 and 6.

In this state, remove the connecting rod and attach the cylinder to the frame 3.
When the coil 14 is opened, as shown in FIG. 6, the lower part of the coil 14 is pushed by the tip 9a of the claw 9, and the coil 14 is guided by the inclined outer surface of the winding part 12 and the inclined surface 8 of the claw 9 to separate from the bobbin 10.

Immediately before that, insert the bar 16 that supports each coil into the hole 11, and with the frame 3 fully opened, each coil 1
4 are all suspended on the bar 16.

This bar 16 is moved back and forth by a drive unit that performs arbitrary linear motion, and is lifted up through the hole 11 and attached to the bobbin 10.
be moved away from the site to a designated location.

That is, each coil is taken out from the coil winding member in a ring shape, with the lower end thereof being clipped, and extending over the bar.

As described above, according to this invention, the opposing vertical arms are integrated at the bottom to form a frame, grooves are formed from above on the opposing surfaces of both arms, and the frame has claws facing between the arms on the front side. A plurality of frames are arranged in parallel and movable in the row direction so that the frames can be opened and closed by a cylinder, and the bobbin is constructed from the coil winding part and the collar on the edge of the end face. Both sides of the flange can be inserted between the grooves from above, and a hole is formed on the outer peripheral surface of the winding portion into which the tip of the coil clamping clip is inserted, and a hole extending from the winding portion to the flange is formed on the outer surface of the bobbin. , When each frame is closed, the claw is located at the flange of this hole, and a through hole is formed in the center of the bobbin, and this through hole opens at the top of the bobbin, and the bar is inserted through it. Since the structure allows the coil to be removed upwardly, the coil can be easily removed from the bobbin by opening the frame.

Therefore, there is an excellent effect that the coil winding work can be greatly improved.

[Brief explanation of the drawing]

The drawings show an example of this invention. Figure 1 is a front view without the coil winding member attached, Figure 2 is a plan view with the coil winding member attached, and Figure 3 is a side view of the figure 2. , FIG. 4 is a partial perspective view of FIG. 1, and FIGS. 5 and 6 are explanatory views of removing the coil.
