It is located above the side lead cutter 83.

In the present embodiment, a plurality of types of lead contact members 95 (for example, a first lead contact member 95a and a second lead contact member 95b described later) may be attached to the upper end surface of the lead holding portion 90. However, the plural types of lead contact members 95 differ in the configuration of the turning side gripping surface 96 and the positioning piece 97 depending on the wire diameter of the lead 142 in the radial component 140 and the like. In the following description, the lead contact member 95 may be used as a general term for a plurality of types of lead contact members.

As shown in FIG. 6 and FIG. 7, the turning side gripping surface 96 is constituted by the end surface of the lead contact member 95 on the side of the fixing member 70, and is located between the fixing member 70 and the turning member. It faces the compliant component 135. That is, the turning-side gripping surface 96 faces the fixed-side gripping surface 73 of the fixing member 70 with the lead 142 taped to the carrier tape 145 of the tape-making component 135 being sandwiched. The turning-side gripping surface 96 is located closer to the tape-making component 135 than the cutting edge of the turning-side lead cutter 83 when the lead holding portion 90 is turning together with the turning body 81.

The turning side gripping surface 96 is configured as a flat surface that is inclined with respect to the mounting surface 99 of the lead contact member 95 so as to form a predetermined inclination angle, and the inclination angle is the line of the lead 142. It is determined according to the diameter. Specifically, the inclination angle of the turning-side gripping surface 96 is determined as an angle that is parallel to the fixed-side gripping surface 73 when the lead 142 is gripped with the fixed-side gripping surface 73.

A positioning piece 97 is formed on the upper end surface of the lead contact member 95 so as to project toward the tape-forming component 135 side with respect to the turning side gripping surface 96 of the lead contact member 95. As shown in FIG. 5, a pair of notches 98 is formed at the edge of the positioning piece 97. The pair of notches 98 are formed according to the wire diameter and the pitch of the pair of leads 142 in the radial component 140 of the tape-formed component 135.

With such a structure, the cutting device 65 cuts the lead 142 and the carrier tape 145 taped to the carrier tape 145 with the rotation of the rotating member 80, and separates the radial component 140 from the carrier tape 145.

More specifically, first, when the rotating member 80 is rotated in the direction in which the upper end of the rotating member 80 approaches the tape-making component 135, the carrier tape 145 is inserted into the pair of notches 98 of the positioning piece 97. A pair of taped leads 142 enter. As a result, the taped radial component 140 is positioned between the fixed member 70 and the rotating member 80. Then, the pair of leads 142 are sandwiched between the turning side gripping surface 96 of the turning member 80 and the fixed side gripping surface 73 of the fixing member 70. As a result, the radial component 140 having the pair of leads 142 is held at the predetermined position.

After that, when the rotating member 80 is further rotated, the lead holding portion 90 is restricted from further rotation due to the contact of the rotating side holding surface 96 with the fixed side holding surface 73 via the lead 142. However, the rotating body 81 further rotates. At this time, the turning side lead cutter 83 of the turning side cutter holding portion 82 approaches the fixed side lead cutter 75 of the fixing member 70 and is sandwiched by the turning side gripping surface 96 and the fixing side gripping surface 73. The pair of leads 142 are cut by the turning side lead cutter 83 and the fixed side lead cutter 75. At the same time, since the turning tape cutter 84 of the turning cutter holding portion 82 approaches the fixed tape cutter 76 of the fixing member 70, the carrier tape 145 of the tape-ized component 135 turns with the fixed tape cutter 76. It is cut by the side tape cutter 84.

Thereby, in the cutting device 65, the radial component 140 is separated from the carrier tape 145, and the radial component 140 is supplied at the position positioned by the positioning piece 97. That is, the lead 142 of the radial component 140 is positioned by the notch 98 of the positioning piece 97, and is sandwiched between the turning side gripping surface 96 and the fixed side gripping surface 73, so that the lead 142 is supplied so as not to fall.

In the tape feeder 55 according to the present embodiment, the operation of the cylinder 110 causes the feeding device 60 and the cutting device 65 to operate integrally with each other, thereby feeding the tape-forming component 135 and removing the tape-forming component 135 from the tape-forming component 135. And the radial component 140 can be separated.

Specifically, first, by the operation of the cylinder 110, the contact block 63 of the delivery device 60 is slid forward while being biased forward by the elastic force of the spring. The holding unit 61 holding the claw member 62 also slides forward together with the contact block 63. Here, as described above, since the claw member 62 is engaged with the feed hole 146 of the tape-formed component 135 when sliding forward by a predetermined amount, the claw member 62 slides forward as a result. The tape-formed component 135 is fed forward by a predetermined amount.

The plate cam 106 also slides forward by the operation of the cylinder 110 in this case. In the following description, the position of the plate cam 106 before the operation of the cylinder 110 is referred to as a neutral position, and the roller 85 is in close contact with the first portion 107 with respect to the plate cam 106 at the neutral position.

Then, by the operation of the cylinder 110, the plate cam 106 moves from the neutral position to the front, and until the contact surface with the roller 85 moves from the first portion 107 to the third portion 109, the delivery device 60 is The state in which the claw member 62 is engaged with the feed hole 146 of the carrier tape 145 is maintained, and the engagement of the claw member 62 with the feed hole 146 is released at a predetermined timing. As a result, the tape-forming component 135 is stopped when a predetermined amount is fed to the front side of the tape feeder 55. During this time, since the contact surface with the roller 85 remains the first portion 107 of the plate cam 106 (see FIG. 8), the rotating member 80 of the cutting device 65 does not rotate, and the radial part 140 does not rotate. There is no need for gripping and separating.

By the operation of the cylinder 110, the plate cam 106 is slid further forward from the state shown in FIG. 8 to move the contact surface of the roller 85 to the plate cam 106 from the first part 107 to the third part 109 (see FIG. 9). ). At this time, the contact surface with the roller 85 moves from the first portion 107 to the third portion 109, so that the roller 85 moves in a direction away from the plate cam 106. As a result, in the cutting device 65, the rotating member 80 rotates about the shaft 100, and the upper end portion thereof approaches the tape-forming component 135.

Then, by operating the cylinder 110, the plate cam 106 is slid further forward from the state shown in FIG. 9 to move the contact surface of the roller 85 to the plate cam 106 from the third portion 109 to the second portion 108 (FIG. 10). At this time, the contact surface with the roller 85 moves from the third portion 109 to the second portion 108, so that the roller 85 further moves in a direction away from the plate cam 106.

At this time, in the cutting device 65, since the rotating member 80 further rotates about the shaft 100, as described above, the pair of leads 142 taped on the carrier tape 145 rotate with the fixed-side gripping surface 73. While being sandwiched by the side gripping surface 96, the pair of leads 142 are cut by the fixed side lead cutter 75 and the rotating side lead cutter 83. At the same time, the carrier tape 145 of the tape-forming component 135 is cut by the fixed-side tape cutter 76 and the rotating-side tape cutter 84. That is, while the feeding device 60 stops feeding the tape-formed component 135, the cutting device 65 holds the pair of leads 142 taped to the carrier tape 145, and the pair of leads 142 and the carrier tape 145 are held. Be disconnected.

Then, after the plate cam 106 slides to the position shown in FIG. 10, the plate cam 106 is slid backward by the operation of the cylinder 110 and returned to the neutral position. At this time, the close contact of the roller 85 with the plate cam 106 is maintained by the elastic force. Therefore, in the cutting device 65, the rotating member 80 rotates in the direction in which the upper end portion thereof is separated from the tape-forming component 135.

At this time, in the delivery device 60, the contact block 63 slides backward against the elastic force of the spring by the operation of the cylinder 110, and the holding unit 61 also slides rearward together with the contact block 63. At this point, the engagement of the claw member 62 with the feed hole 146 of the tape-formed component 135 is released, so that the tape-formed component 135 cannot be fed back in the reverse direction when the holding unit 61 is slid backward. To be prevented. Then, when the holding unit 61 is slid to the rear end position, the claw member 62 is engaged with the feed hole 146 of the tape-formed component 135.

As described above, in the tape feeder 55, the operation of the cylinder 110 causes the feeding device 60 and the cutting device 65 to work in unison with each other. That is, the cylinder 110 is shared as a drive source for the delivery device 60 and the cutting device 65. As a result, the number of drive sources can be minimized, and the installation space of the drive sources, the cost required for the drive sources, etc. can be suppressed.
