  Next, as shown in FIG. 13, by raising the piston rod 153 of the cylinder 152 of the gripping means 15 in FIG. 6, the half coil 1A is lifted by the gripping frame 154 and the gripping claws 156 of the gripping means 15. Thereafter, the beam 142 of the rocking means 14 is moved to convey the half coil to the center position of the apparatus shown in FIG.

  Next, as shown in FIG. 14, the pin 147 on the moving body 9 in FIG. 2 is pulled out from the hole 149 by the cylinder 145, and then the swinging cylinder 143 is contracted, so that the beam 142 as shown in FIG. Is swung counterclockwise with the pin 146 as a fulcrum. Thereafter, the piston rod 153 of the cylinder 152 in the gripping means 15 is lowered, and the half coil 1A is placed on the pedestals 6 and 7 in an oblique state.

  Next, in FIG. 15, the cylinder 143 shown in FIG. 1 is extended, the beam 142 is returned straight, the pin 147 on the moving body 9 is reinserted into the hole 149 by the cylinder 145, and then the screw shaft 11 is rotated. The movable body 9, the beam 142 and the gripping means 15 are returned to the position just above the carry-in conveyor 4, and finally the piston rod 153 of the cylinder 152 is extended to load the gripping frame 154 and gripping claws 156 in the gripping means 15. It is lowered into the conveyor 4 and returned to the initial position.

  Next, in FIG. 16, the half coil 1 </ b> B is carried into the apparatus by the carry-in conveyor 4, whereby the half coil 1 </ b> B is set on the grip frame 154 and the grip claws 156 in the grip means 15.

  However, the half coil 1B carried in at this time is carried into the carry-in conveyor 4 in a state opposite to the front and back with respect to the carried half coil 1A shown in FIG. Further, as shown in FIG. 31, in the half coil 1B, a sheet C impregnated with a resin in advance is inserted in each dislocation portion.

  Next, in FIG. 17, the piston rod 153 of the cylinder 152 in the gripping means 15 shown in FIG. 6 is contracted, the gripping frame 154 and the gripping claws 156 in the gripping means 15 are raised, and the half coil 1B is lifted. Thereafter, the screw shaft 11 is rotated to move the moving body 9, the beam 142, and the gripping means 15 to the carry-out conveyor 5 side, and convey the half coil 1B to the center position of the apparatus. Then, the gripping frame 154 and the gripping claws 156 in the gripping means 15 are lowered, and the half-coil 1B is placed in a straight state (the left-right direction in FIG. 17) on the half-coil 1A and the pedestals 6 and 7 that are arranged obliquely in advance. Put on.

  Next, in FIG. 18, the pin 147 and the hole 149 are disengaged by the cylinder 145, and the swinging cylinder 143 in FIG. After swinging clockwise as a fulcrum and releasing the half coil 1B by the gripping claws 156 in the gripping means 15, the piston cylinder 153 of the cylinder 152 in the gripping means 15 is contracted, and the gripping claws 156 in the gripping means 15 are moved. Raise. Thereafter, the swinging cylinder 143 in FIG. 1 is contracted, and the beam 142 is swung counterclockwise with the pin 146 as a fulcrum, so that the swing angle between the straight half coil 1B and the first half coil 1A is Swing to an intermediate angle. Then, the piston rod 153 of the cylinder 152 in the gripping means 15 is lowered, the gripping frame 154 and the gripping claws 156 in the gripping means 15 are lowered, and finally the swinging cylinder 143 is contracted, so that the beam 142 is moved to the first half coil. It is swung until it becomes the same angle as that of 1A (it is swung counterclockwise with the pin 146 as a fulcrum). As a result, the openings of the gripping frame 154 and the gripping claws 156 in the gripping means 15 are inserted into the half coil 1A that is first carried in, and the setting for lifting the half coil 1A is completed.

  Next, in FIG. 19, first, the positioning arm 72 is vertically projected by the rotary actuator 71 provided on the cradle 7 shown in FIGS. 10 and 11, and the half coil 1B is moved on the surface of FIG. Hold down. Then, the piston rod 153 of the cylinder 152 in the gripping means 15 in FIG. 6 is raised, and the first half coil 1A that is carried in is lifted by the gripping frame 154 and the gripping claws 156 in the gripping means 15. Then, by extending the gripping claw tilting cylinder 158 in FIG. 6, the gripping claw 156 is rotated about the pin 157, and the half coil 1A gripped by the gripping claw 156 is tilted. At this time, since the side surface of the half coil 1A engages with the engagement protrusion 155 of the grip frame 154, the half coil 1A is prevented from dropping from the grip claws 156.

  Next, in FIG. 20, when the beam 142 is swung in the clockwise direction with the pin 146 as a fulcrum by extending the swinging 143 in FIG. 1, an area a indicated by a two-point difference line between the half coil 1A and the half coil 1B. And area b are overlaid.

  FIG. 21 shows operations of the gripping frame 154 and the gripping claws 156 of the gripping means 15 when the half coil 1A and the half coil 1B are overlapped. FIG. 21 is a view taken in the direction of arrows XX-XX in FIG.

  Here, as shown in FIGS. 19 and 21, the reason why the half coil 1A is tilted by the gripping means 15 and swung as shown in FIG. 20 in this state will be described with reference to FIG. 22 is a view taken along the line XX-XX in FIG. In FIG. 22, 1A is a half coil that is first carried in, and 1B is a half coil that is carried in a state where the sheet C impregnated with resin is sandwiched between the front and back sides of the half coil 1A. . In FIG. 22, when the half coil 1A is tilted by the gripping means 15, the half coil 1A is in a state of opening its mouth. In this state, the sheet Ca impregnated with the resin is inserted without being caught in the mouth portion of the half coil 1A by swinging the half coil 1A as shown in FIG. 20, and the sheet Ca impregnated with the resin is inserted. This makes it possible to perform good overlay without being caught.

  Next, in FIG. 23, the gripping claw tilting cylinder 158 is contracted to release the inclination of the gripping claw 156, and the engagement between the half coil side surface and the engaging projection 155 of the gripping frame 156 is also released. Further, the pin 147 on the moving body 9 in FIG. 2 is inserted into the hole 149 by the cylinder 145, the pin 146 is extracted from the hole 148 by the cylinder 144, and the swing fulcrum of the beam 142 is switched from the pin 146 to the pin 147.

  Thereafter, in FIG. 24, by contracting the swing cylinder 143 in FIG. 1, the beam 142 swings clockwise with the pin 147 as a fulcrum. At that time, since the half coil 1A is hooked on the arm 72 of the pedestal 7, the gripping claws 156 of the gripping means 15 are detached from the half coil 1A.

  Next, in FIG. 25, the piston rod 153 of the cylinder 152 in the gripping means 15 in FIG. 6 is extended, and the gripping frame 154 and gripping claws 156 in the gripping means 15 are lowered. Then, the cylinder 143 for swinging in FIG. 1 is extended, and the beam 142 is swung counterclockwise with the pin 147 as a fulcrum. Place on coil 1B.

  Next, in FIG. 26, the gripping claw tilting cylinder 158 is contracted to release the tilting of the gripping claw 156, and the engagement between the half coil side surface and the engaging projection 155 of the gripping frame 154 is also released.

  Next, in FIG. 27, the positioning plate 62 is pushed out by the cylinder 61 provided on the cradle 6 shown in FIGS. 8 and 9, and the beam 142 is moved downward in FIG. 27 by driving the screw shaft 11 in FIG. Move.

  Thereafter, as shown in FIG. 28, the screw shaft 11 is driven to move the movable body 9 and the beam 142 until the gripping claws 156 of the gripping means 15 are located directly above the carry-out conveyor 5. By extending the piston rod 153 of the cylinder 152, the completed dislocation coil can be placed on the carry-out conveyor 5. Thereafter, by driving the carry-out conveyor 5, the completed dislocation coil is carried out of the apparatus (right side in FIG. 28).

  By the above operation, the operation of superimposing the half coils having three dislocation groups previously knitted with half of the strands necessary for manufacturing the dislocation coil can be automated.

  In the above-described knitting operation, the description has been given by taking as an example the superposition operation of the half coils having three dislocation groups, but in FIG. 23, the oscillation center of the beam 142 is not switched from the pin 146 to the pin 147. Thereafter, the operation shown in FIG. 26 described above is performed first, and the operations described in FIGS. 24, 25, 27, and 28 can be performed, so that half coils having two dislocation groups can be overlapped. It is.

  In the above-described embodiment, a screw and screw shaft driving device is used as the moving means of the moving body 9, but a cylinder driving device can also be used. Further, although the swinging cylinder 143 is used for swinging the beam 142, a driving motor can be provided on the movable leg 141.

  According to the embodiment of the present invention, it is possible to mechanize and automate the superposition operation of the half coils with respect to the manufacture of the coil with the narrowed pitch of the dislocation portion of the coil. Reduction can be achieved. As a result, the manufacturing cost can be reduced. In addition, when the half coils are overlaid, the portion where the sheet impregnated with resin is to be inserted can be opened to eliminate the catching of the sheet on the coil, thereby preventing a decrease in product reliability. The speed of the apparatus can also be increased.
