It is composed of a resin rod or the like which is shorter than the interval. The mounting table 210 raises and receives the bobbin reel B transferred by the lifting rod 196 described above, and receives and holds the bobbin reel B by the guide plate 211 and the support rod 212.

The pay-out mechanism 170 moves the slider 181 to the take-out position immediately below the bobbin reel B during the winding of the carrier tape C onto the bobbin reel B or after the winding is completed, and separates the link member 185 of the slider 181. Rock in the direction. When the winding of the carrier tape C is completed and the carrier tape C is cut by the cutting mechanism 20, the bobbin reel B falling between the reel side plates 114 and 115 is received on the bar 187, and the slider 181 moves in the tape running direction. Move to T to the transfer position.

In addition, the slider 192 is previously moved to the transfer position by the elevating cylinder 194 to lower the insertion cylinder 195 to a predetermined position and waits. When the slider 181 reaches the transfer position, the insertion cylinder 195 lifts the lifting rod. 196 is inserted into the hole Bc of the bobbin reel B, the elevating cylinder 194 is actuated to lift the bobbin reel B, and the slider 192 moves right above the mounting table 210. After that, when the slider 192 reaches directly above the mounting table 210, the mounting table 210 causes the cylinder 213 to extend so that the mounting plate 211 and the support rod 212 come into contact with the bobbin reel B, and in this state, the lifting rod 196. The cylinder 195 is pulled out from the hole Bc of the bobbin reel B. Then, the mounting table 210 lowers the mounting plate 211 and the support rod 212.

In the winding device 1 according to this embodiment, the carrier tape C molded by the molding machine is introduced via the dancer roll 10, and the introduced carrier tape C is grasped by the guide 36. The bobbin reel B is sandwiched between the reel side plates 114 and 115 of the rotation drive mechanism 110, and the bobbin reel B is rotationally driven to wind up the carrier tape C. When the winding of the carrier tape C is started, or when the carrier tape C is wound on a new bobbin reel B, first,
The carrier tape C is cut by the cutting mechanism 20, and the grip arm 37 is swung to sandwich the cut end of the carrier tape C between the grip jig 39 and the grip guide 36 (FIGS. 5a and 5b).

Thereafter, the tilting bracket 34 is tilted so that the cut end of the carrier tape C is directed obliquely upward in the tape running direction T (FIG. 6a), and in this state the slide table 3 is moved.
1 is moved toward the bobbin reel B of the rotary drive mechanism 110 (FIG. 6b), and the cut end of the carrier tape C is brought into surface contact with the winding core surface of the bobbin reel B. When the cut end of the carrier tape C comes into surface contact with the winding core surface of the bobbin reel B, the tilt bracket 34 is tilted to move the carrier tape C.
Are tangentially extended with respect to the core surface (FIG. 7).

On the other hand, in the fastening mechanism 50, the rolls 53 and 54 are rotated by a predetermined rotation angle (number) in response to the movement of the slide table 31, and the adhesive tape piece 55 attached to the release film 56 is removed. The adhesive tape piece 55 is peeled by the peeling member 57, and is guided to the suction pad 58 by the compressed air blown from the air nozzle 79 (FIG. 5A).
Then, the adhesive tape piece 55 is adsorbed and held with the adhering surface as the lower surface on the adsorbing pad 58 to which the negative pressure is introduced (FIG. 4).
b).

Then, the elevating rod 52 descends to press the suction pad 58 against the core surface of the bobbin reel C, and the adhesive tape piece 55 on the lower surface of the suction pad 58 is cut off the carrier tape C and the core of the bobbin reel C. Affixing is carried out across the surface (FIG. 8a), and the lifting rod 52 is raised after the bonding (FIG. 8b). Therefore, the cut end of the carrier tape C is fixed to the bobbin reel B.

After that, the winding motor 121 is energized to rotate the bobbin reel B, and at the same time, the winding motor 121 is reciprocally driven in the direction of the rotation center axis by the servo motor 119, and the bobbin reel B is supplied with the carrier tape. C is wound in a spiral shape. That is, the rotation of the bobbin reel B is detected by an encoder, the rotation speed of the servo motor 119 and the switching timing of forward and reverse rotation are controlled based on the output of the encoder, and the carrier tape C is wound around the bobbin reel B at a predetermined pitch. take. Therefore, bobbin reel B
The winding length of the carrier tape C to be wound up can be increased.
Further, since the maximum value of the transmission torque of the winding motor 121 is regulated by the powder clutch 122, the tension at the time of winding the carrier tape C does not become excessive, and the winding can be performed at an appropriate tension.

Further, during winding of the carrier tape C on the bobbin reel B, the slider 181 moves to the bobbin reel B.
Of the slider 181 swings in the direction in which the link member 185 of the slider 181 separates, and the receiving bar 187 waits so that the bobbin reel B can be received. The insertion cylinder 195 is lowered to a predetermined position by 194 and stands by. Then, when the winding of the carrier tape C onto the bobbin reel B is completed and the carrier tape C is cut by the cutting mechanism 20, the movable support member 113 fixes the movable support member 113.
Moving away from the plunger 12
4 protrudes, and the bobbin reel B on which the winding is completed falls on the receiving bar 187.

After this, the slider 181 is moved to the bobbin reel B.
When the slider 181 reaches the transfer position by mounting it on the receiving bar 187 and moving to the transfer position, the insertion cylinder 195 causes the lifting rod 196 to move the lifting rod 196 to the bobbin reel B.
And the bobbin reel B is lifted. Then, the moving cylinder 193 operates to convey the slider 192 to the payout position and pays out the bobbin reel B. After that, the slider 192 moves to the transfer position and prepares next.

Further, almost at the same time when the slider 181 moves toward the transfer position, the swing arm 156 swings to the delivery position to move the empty bobbin reel B to the reel side plate 11.
Lift between 4,115. Then, the movable support member 11
3 is driven to the side of the fixed support member 112 and the reel side plate 11
The bobbin reel B is sandwiched between 4,115. After this,
Similarly, the carrier tape C is provided on the winding core surface of the bobbin reel B.
The bobbin reel B is rotated, and the bobbin reel B is reciprocated in a predetermined range in the direction of the rotation center axis to wind up the carrier tape C on the bobbin reel B, and this is repeated thereafter. Therefore, the carrier tape C can be efficiently wound around the bobbin reel B without manual work of the operator.
