Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for forming a cup-shaped rotor winding body of a coreless motor, for example.

This type of winding device is used for a turntable 1 as shown in FIG.
Attach pulse motors 4 and 5 to each stage 2 and 3 above,
Winding frames 7 and 8 are attached to each of the rotating shafts 6, and a rotating shuttle 9 is provided to wind the coil wire around the winding frame 8 at a predetermined position, for example, the lower position in FIG. 1 of the shuttle 9 based on the output of the rotation detection means 10 of the shuttle 9.
For each rotation, the pulse motor 5 is rotated by one step corresponding to the length of the coil wire, and when the shuttle 9 completes winding at a predetermined number of rotations, the pulse motor 5 rotates 360 degrees.

In this case, if the winding frame 8 attached to the rotating shaft 6 of the pulse motor protrudes outward from the turntable 1, the turntable 1 can be rotated regardless of the rotational position of the shuttle 9. , the winding device becomes larger. Therefore, the positions of the winding frames 7 and 8 are set within the cover of the turntable 1,
In addition, it is desirable to provide it close to the upper surface of the turntable 1. For this reason, relief grooves 11 are formed in each of the stages 2 and 3 so that the shuttle 9 does not come into contact with them. Further, in order to allow the turntable 1 to rotate, the shuttle 9 is formed in a C-shape and has a insertion portion 12, as shown in FIG. The turntable 1 is rotated so as to fit into the insertion notch 12, but if the turntable 1 collides with the shuttle 9, the shuttle 9 may be damaged. Therefore, a commonly considered safety measure is to provide detection switches 13 and 14 at predetermined positions within each escape groove 11 to detect contact with the shuttle 9, as shown in FIG.

Each detection switch 13, 14 is inserted into a turntable drive circuit 15 or a control circuit 18 of a relay coil 17 that switches a relay switch 16, as shown in FIG.
When either of the detection switches 13, 14 contacts the shuttle 9 and opens, the IJ Ray coil 17 is de-energized and the rotation of the turntable 1 is stopped. The control circuit 18 further includes a switch transistor 9 in series, and this transistor controls the monostable multipipetrator 20 by a turntable drive signal generated by closing a manual switch or the like after the rotation of the shuttle 9 is completed, that is, the winding on the winding frame 8 is completed. It is designed to conduct the output for a certain period of time. In the above-mentioned winding device, if the number of stages on the turntable is increased, the number of detection switches must be increased, which increases the cost, and the detection signal from each detection switch is extracted from the turntable via a slip ring, etc. Must be.

The present invention has been invented in view of these points, and specific examples of the present invention will be described below with reference to FIGS. 3 to 7.

3 is a partial front view of the winding device, and FIG. 4 is a plan view showing the relationship between the winding frame 8 and the shuttle 9. Components that are the same as those in FIG. 1 are given the same reference numerals. A pulse motor 5 as a winding frame mounting means is mounted on the stage 3 of the turntable 1, and a winding frame 8 is mounted on its rotating shaft 6. The shuttle 9 is rotatably supported by a holding means (not shown) so as to be inclined with respect to the rotating shaft 6, and is supported by a plurality of rollers 21, 2.
A wire storage bobbin 22 is attached to the shuttle 9, and a coil wire 23 from the bobbin is supplied to the winding frame 8 via a pulley 24. A rotation detection means 10 for detecting rotation of the shuttle 9 is provided near the shuttle 9. The detection means consists of a reed switch 25, and a permanent magnet 26 is attached to the shuttle 9.

The rotation detection means 10 is provided to detect one rotation of the main shuttle 9 and rotate the pulse motor 5 by one step. The mounting position of the permanent magnet 26 is selected so that a detection output can be obtained at a corresponding position, that is, a position where the turntape can pass through the notch 12. FIG. 5 shows the first control circuit of the turntable drive means 27, and the control circuit 18 of the IJ Ray coil 17, which is inserted into the turntable drive circuit 15 and switches the race switch 16, includes the detection switch 13 shown in FIG.
14 is not present, and the base of the switch transistor 19 inserted in the control circuit is connected to the output of a monostable multipipe layer control circuit 20 which receives a turntable drive signal generated by closing a manual switch, etc., and the shuttle stationary circuit. and the detection output of the time rotation detection means 10 as an input.
The output of circuit 27 is applied. Therefore, even if a turntable drive signal is issued, when the notch 12 of the shuttle 9 does not correspond to the turntable 1, there is no detection output of the rotation detection means 10, that is, the output is "L", so the l-th
The output of the AND circuit 28 remains "L", the switch transistor 19 remains cut off, the turntable drive circuit 15 is in an inactive state, and the turntable 1
There is no collision with the shuttle 9 due to the rotation of the shuttle. In this state, when the shuttle 9 is rotated so that the notch 12 of the shuttle 9 corresponds to the position of the turntable flue, the detection output of the rotation detection means 10 becomes "H", and the turntable drive circuit 15 is activated. , Stage 2, which follows Turntaple, comes to oppose Shuttle 9. Next, FIG. 6 shows a second control circuit for the turntable driving means 27.
9 and 30 are first and second NAND circuits, 31 is a trigger flip-flop circuit, 32 is a second monostable multipipulator, 33 is an R-S flip-flop, and 34 is a second A
The ND circuits 35, 36, and 37 are first, second, and third NOT circuits, and each circuit is connected as shown.

38 is a shuttle drive circuit, and a second switch transistor 41 is connected to the base of a switch transistor 41 in which four relay coils are connected in series to switch a relay switch 39 inserted in the drive circuit.
The output of the AND circuit 34 is applied.

42 is a shuttle drive control circuit which together with the loaf 21 constitutes a drive means for the shuttle 9.

In the second control circuit, the detection output a of the rotation detection means 10
When the turntable drive signal is "L" and the turntable drive signal is "H", the output b of the INAND circuit 29 becomes "H".
The trigger flip-flop circuit 31 is not reset, its Q output is "L", and the output of the AND circuit 30 which receives the "L" signal of the detection output a becomes "H". Therefore, the output d of the second monostable multipipulator circuit 32 becomes "H" for a certain period of time, and when this output d "H'' and the inverted signal "H" from the INOT circuit 35 of the detection output a are input, The switch transistor 19 becomes conductive at the output of the first AND circuit 28, and the turntable drive circuit 15
operate. In this case, since the "H" of the output c is inverted to "L" by the OT circuit 37, the R-S flip-flop circuit 33 is reset and its Q output is "L", and the shuttle drive circuit 38 is inactive and the shuttle 9 is stationary. Next, the turntable drive signal is “H”.
”, when the notch 12 of the shuttle 9 does not correspond to the turntape, the detection output a of the rotation detection means 10 is “H”, so the output b of the INAND circuit 29 is “L”. Therefore, the trigger flip-flop circuit 3
1 is reset and the output c of the AND circuit 30 is set to “L”.
Therefore, the output d of the second monostable multipipelator circuit 32 remains at "L", and the turntable drive circuit 15 remains in an inactive state.

In this case, the turntable drive signal "H" is inverted by the OT circuit 36 and becomes "L", giving a set input to the R-S flip-flop circuit 33, and the output c becomes "L".
Therefore, since the circuit 33 is not reset, the circuit 3
The Q output e of No. 3 becomes "H", which makes the switch transistor 41 conductive through the second ND circuit 34, and the relay coil 40 is energized to close the relay switch 39 and the shuttle drive circuit 38 is activated.

Therefore, the shuttle 9 rotates, and the notch 12 of the shuttle 9 rotates.
When the rotation detecting means 10 reaches the corresponding position on the turntable 1, the detection output a of the rotation detecting means 10 detects the position and becomes "L", so that the turntable drive circuit 38 is inactivated as described above. As described above, according to the present invention, the rotating shuttle for supplying and winding the coil wire around the winding frame is formed into a C-shape, and is provided with a notch for insertion of the turntable. Since the rotation detecting means for detecting the rotation of the shuttle generates a detection output at a position where the shuttle can be inserted, if the turntable is driven based on the detection output, the turntable will move through the notch. Since the turntable can be inserted through the shuttle, it is possible to avoid a situation where the turntable collides with the shuttle.

Furthermore, since the rotation detecting means is originally required when winding the coil wire from the shuttle around the winding frame, there is no need to separately provide a special detecting means for driving the turntable. Since the circuit detection means is provided near the shuttle, there is no need to extract an abnormality detection signal from the turntable via an IJ spring or the like as in the prerequisite device of the present invention, and the mechanism is simple and inexpensive. Further, when the turn table driving means includes means for rotating the shuttle until the detection output is obtained when there is no detection output from the rotation detection means when the turntable drive signal is received, The turntable can be reliably and safely rotated by the turntable drive signal.
