That is, the component P located at the supply position SS is held by the mounting head 20 including the chuck device 36 described above and mounted on the substrate S. By the way, FIG. 7 shows a portion where the supply position SS exists from a front right obliquely upper perspective.

ii) Feeding Mechanism Explaining with reference to FIG. 8 showing a state in which the outer cover is removed, the tape-formed component TP is held by the guide rail 62 provided in the guide groove 60. The guide rail 62 has a lower portion bent leftward in a U-shape and an upper portion bent rightward to form a flange. Although the taped component TP is not shown in the drawing, the taped component TP is held on the left side of the guide rail 62 in a state where the lower portion is accommodated in the U-shaped portion. The parts feeder 26 includes a feeding mechanism 70 that sends the taped parts TP in that state forward.

The feed mechanism 70 is supported by the feeder main body, a first slide 72 movably supported by the feeder main body in the front-back direction, a double-acting air cylinder 74 that is an actuator that reciprocates the first slide 72 in the front-back direction. The second slide 76 that reciprocates in the front-back direction in accordance with the operation of the first slide 72, the support bar 78 that operates integrally with the second slide 76, and the support bar 78 that rotates through the bracket 80 and the bracket 82. The feed claw 84 and the feed claw 86 are movably supported.

When the first slide 72 is moved forward by the air cylinder 74, the spring 88, which is a tension coil spring passed between the feeder main body and the second slide 76 (strictly speaking, the support bar 78), moves the first slide 72. The second slide 76 moves forward while being in contact with the first slide 72. A stopper 90 is attached to the feeder main body, and when the stopper 90 is moved to a certain distance, the second slide 76 is locked by the stopper 90 and the forward movement is stopped. In that state, only the first slide 72 is allowed to move forward. When the first slide 72 is returned to the rear by the air cylinder 74, at a certain position, the first slide 72 contacts the second slide 76 locked by the stopper 90, and thereafter, the second slide 76 is contacted. Moves backward with the first slide 72.

The feed claw 84 and the feed claw 86 have their base end portions rotatably supported by a bracket 80 and a bracket 82 fixed to the support bar 78, respectively, and are rotatable in a horizontal plane. .. The tips of the feed claws 84 and 86 face the left side. A spring 92, which is a compression coil spring, is arranged between each bracket 80, 82 and each feed pawl 84, 86, and each feed pawl 84, 86 is biased in the direction in which the tip end thereof moves to the left side. ing.

A locking plate 94 is arranged between the guide rail 62 and the support bar 78 so as to extend in the front-rear direction. In the state shown in the figure, that is, in the state where the support bar 78 is located rearward, in other words, when the second slide 76 is located at the rear end of the moving range, the feeding claws 84 and 86 are not moved. The tip end is brought into contact with the locking plate 94 by the biasing force of the spring 92.

Referring also to FIGS. 9A and 10A, which are enlarged views of the portion where the feed claw 84 is disposed, FIG. 9A is shown when the support bar 78 is located rearward. As shown in, the tip of the feed claw 84 is in contact with the locking plate 94. On the other hand, when the second slide 76 advances and the support bar 78 advances, the feed claw 84 also advances, and the tip of the feed claw 84 protrudes from the end of the locking plate 94, as shown in FIG. By the urging force of the spring 92, the feed claw 84 is rotated to a position exposed from the opening of the guide rail 62. Although illustration is omitted, as the support bar 78 advances, the feed claw 86 is also operated in the same manner, the tip of the feed claw 86 protrudes from the long hole provided in the locking plate 94, and the urging force of the spring 92 guides it. The feed claw 86 is rotated to a position where it is exposed from the opening of the rail 62.

The distance between the tip of the feed claw 84 and the tip of the feed claw 86 is set to an integer multiple (p2×n) of the hole pitch p2 of the feed holes FH provided in the tape-formed component TP, and the engagement by the locking plate 94. When the stop is released, the tips of the feed claws 84 and 86 are inserted into different feed holes FH at the same time. By further advancing the support plate 78 after the insertion, the tape-formed component TP is sent by the amount of the advance. The amount of further advance is adjusted to be equal to the hole pitch p2.

As can be seen from FIGS. 9A and 10A and FIGS. 9B and 10B (the feed claws 84 are omitted) shown from the viewpoint from above, the guide rail 62 is A check claw 96 is rotatably arranged on the side opposite to the feed claws 84 and 86, that is, on the left side of the tape-formed component TP. If the front side is called the downstream side in the feeding direction of the tape-formed component TP and the rear side is called the upstream side, the check claw 96 is provided on the downstream side of the feeding claw 84. The check claw 96 is biased to the right by the force of the spring 98, which is a compression coil spring, and is inserted into the feed hole FH when the tape-formed component TP is fed by the above-described amount of advance. When the check claw 96 is inserted into the feed hole FH, the tape component TP is prohibited from being displaced to the upstream side. Note that the check claw 96 has an inclined surface on the upstream side at the tip thereof, and even when it is inserted into the feed hole FH, when the taped component TP is fed to the downstream side, it is fed. Due to the force, it resists the biasing force of the spring 98 and separates from the feed hole FH.

By retracting the first slide 72 while the check claw 96 is inserted in the feed hole FH, the feed claw 84 and the feed claw 86 are also retracted while the taped component TP maintains its position. .. As can be seen from the operation described above, the feed mechanism 70 engages the feed pawl 84 and the feed pawl 86 with the feed hole FH and moves the feed pawl 84 and the feed pawl 86 to move the tape-formed component TP. Is configured to be fed in the feed direction, and the tape-shaped component TP is fed to the downstream side by the feed pitch p3 equal to the hole pitch p2 and the arrangement pitch p1 by one forward/backward movement of the air cylinder 74. Has been done.

iii) Positioning Mechanism and Lead Cutting Mechanism The present component feeder 26, as shown in FIGS. 7 and 8, is a mechanism for positioning the component P at the above-mentioned supply position SS, specifically, as shown in FIG. The P has a positioning mechanism 108 for determining the positions of the two leads Le in the feed direction. Further, the positioning mechanism 108 is combined with a mechanism for cutting an extra portion of the two leads Le of the component P located at the supply position SS.

Explaining in detail with reference to FIGS. 7, 8, 11, and 12, the positioning mechanism 108 roughly includes a first member and a second member that are two members that move relative to each other. The clamp 110 that opens and closes is configured as a main component. Specifically, the clamp 110 is configured to include a fixing block 112 fixed to the feeder main body and a lever 114 that is swingably held by the feeder main body. Incidentally, the lever 114 functions as one of the first member and the second member, and the fixed block 112 functions as the other of the first member and the second member.

The lever 114 is composed of a main lever 116 whose upper end is branched into two, and a sub-lever 118 which intersects the main lever 116 by utilizing the branched portion. It is possible to swing. As can be seen from FIG. 12A, the upper end of the main lever 116 is biased to the right by the biasing force of the spring 122, which is a compression coil spring, and the sub-lever 118 is the spring 124, which is a compression coil spring. The lower end portion is biased to the right by the biasing force of.

A blade 126 is attached to the upper end of the main lever 116, and a holding plate 128 is attached to the upper end of the sub lever 118. A roller 130 is attached to the lower end portion of the main lever 116. As shown in FIG. 8, the roller 130 functions as a cam follower, and when the first slide 72 moves forward, the roller 130 moves. It is adapted to engage with a cam surface 132 provided at the front end portion.

The biasing force of the spring 122 is larger than the biasing force of the spring 124, and in the state shown in FIG. 12A, the sub-lever 118 contacts the back surface of the blade 126 and the upper end of each of the main lever 116 and the sub-lever 118. Is located on the right side, that is, the clamp 110 is open. In this state, both the blade 126 and the holding plate 128 are separated from the fixed block 112.

When the first slide 72 moves forward, the main lever 116 swings in the direction in which the upper end moves to the left, and accordingly, the sub lever 118 also swings in the same direction. When the main lever 116 and the sub-lever 118 swing to some extent, as shown in FIG. 12B, between the holding surface 134 provided on the fixed block 112 and the holding surface 136 provided on the holding plate 128. Then, the swing of the sub-lever 118 is stopped while the lead Le of the component P is sandwiched. The portion of the fixed block 112 where the holding surface 134 is provided and the portion of the holding plate 128 where the holding surface 136 is provided each function as a holding portion, and the lead Le of the component P is held by these holding portions. In this state, the lead Le is clamped by the force of the spring 124.

Further, when the main lever 116 swings, the lead Le is cut by the tip of the blade 126 and the lower end of the holding surface 134 of the fixed block 112, as shown in FIG. 12C. The tip of the blade 126 and the lower end of the holding surface 134 of the fixed block 112 function as a pair of blades respectively provided on the above-mentioned first member and second member, and the lead Le causes the pair of blades to move, The tip end side (lower end side) of the portion sandwiched by the sandwiching portion is sheared. That is, the component feeder 26 is provided with the lead cutting mechanism 138 including the pair of blades and cutting the lead Le by the opening/closing operation of the clamp at the supply position SS.

The component whose lead Le has been cut at the supply position SS is held by the chuck device 36 of the mounting head 20 described above with the lead Le being held by the clamp 110, and after the clamp 110 is opened, its mounting is performed. It is moved by the head 20 and provided for mounting on the substrate S. The opening operation of the clamp 110 is performed by utilizing the urging force of the spring 122 and the spring 124 by retracting the first slide 72. Since the operation between the open position shown in FIG. 12A and the closed position shown in FIG. 12B, that is, the opening/closing operation of the clamp 110 is performed along with the forward/backward movement of the first slide 72, It is supposed to be interlocked with the operation of the feeding mechanism 70 described above.

As shown in FIG. 11, a blade 140 and a blade 142 for cutting the carrier tape CT are provided on the front end surface of the fixed block 112 and the front end surface of the main lever 116, respectively. By the opening/closing operation of the clamp 110, a part of the carrier tape CT that has already been supplied with the component P and is left is cut. A part of the cut carrier tape CT is recovered in the waste tape recovery box 56 through the recovery path 144 (see FIG. 6).

In the present positioning mechanism 108, it is important to position each of the two leads Le of the component P at an appropriate position in the feeding direction of the tape-formed component TP. Therefore, a guide portion 150 is provided on the upper end of the lever 114, which is one of the first member and the second member, specifically, on the holding plate 128 attached to the upper end of the sub lever 118.

The holding plate 128 has a thin piece-shaped projecting piece portion 152 protruding from the holding surface 136. Corresponding to the two leads Le, the projecting piece portion 152 has two openings that respectively open toward the fixed block 112 that is the other of the first member and the second member when the clamp 110 is in the closed position. V notches 154 and 154 are formed. When the clamp 110 is closed, the protruding portion 152 moves so as to cover the fixed block 112, and the V notches 154 and 154 cause the two leads Le to move to the defined positions, that is, the valley bottoms of the V notches 154 and 154. Will be guided to the position. As described above, the guide portion 150 is configured to include the plurality of V notches 154 according to the number of the leads Le of the component P.

Depending on the type of the component P, the number of lead Le, the diameter, the position of the lead Le, the spacing between the leads Le, and the like are different, and the number, shape, and spacing of the V notches 154 are changed according to the supplied component P. There is a need to. For example, a positioning mechanism 156 as shown in FIG. 13A, that is, a main body portion (holding portion) of the holding plate 128 described above is integrated with the sub-lever 118, and a thin guide plate 158 (which constitutes the projecting piece portion 152). It is also conceivable to employ a positioning mechanism configured to replace only the guide portion) according to the part P. FIG. 13A shows a state in which the lead Le of the component P is normally sandwiched. However, in the case of such a configuration, FIG. 13B and the side view schematically show the state. 13(c) may cause a problem. More specifically, one of the leads Le is positioned at an appropriate position due to the feed amount of the tape-formed component TP by the feeding mechanism 70 being improper or the lead Le being bent. It is expected that none of the leads Le will fit within the corresponding V-notch 154 opening. In that case, the lead Le contacts the portion of the guide plate 158 where the V notch 154 is not formed when the clamp 110 is closed, and the guide plate 158 bends the lead Le and the tip portion of itself. Is deformed so as to be lifted, and the clamp 110 may reach the proper closed position. By the way, if the lead Le has a small diameter, the possibility becomes particularly high.

In order to avoid such a situation as described above, in the component feeder 26, the holding plate 128 is manufactured in a state in which the main body portion thereof and the projecting piece portion 152 are integrated, and more specifically, the main body portion and the projecting piece portion. 152 is formed from one member, and is configured to be replaced with the sandwiching plate 128 according to the component P. Since such a structure is adopted, that is, the rigidity of the protruding piece portion 152 is relatively high, when the lead Le is not positioned at the proper position in the component feeder 26, the clamp The clamp 110 is not closed to the extent that the closed position of 110 is the proper position. Therefore, by checking whether or not the closed position of the clamp 110 is at the proper position, it is possible to easily check whether or not the position of the lead Le is at the proper position.

iv) Clamp Closed Position Confirmation Mechanism From the above viewpoint, in the component feeder 26, when the lead Le of the component P is clamped by the clamp 110 at the supply position SS, the clamp 110 is closed, that is, the clamp 110 is closed. A clamp closed position confirmation mechanism 160 for confirming whether or not the operating position in the closed state is the proper position is provided.

Specifically, as shown in FIG. 11, the clamping plate 128 is provided with a bulging portion 162 that extends forward from the sub-lever 118, and the detection hole 164 is formed through the bulging portion 162. , The detected hole 164 is detected by a light reflection type sensor 166 disposed below the detected hole 164, and the closed position of the clamp 110 is set to an appropriate position depending on whether or not the detected hole 164 is detected by the sensor 166. It is possible to check whether there is any. That is, the component feeder 26 includes the detected hole 164 as a detected portion provided in the guide portion that is a part of the sandwiching plate 128, and the sensor 166 that detects the detected hole 164, and the clamp closed position. The confirmation mechanism 160 is configured.

More specifically, the state where the clamp 110 is fully closed is the state where the closed position of the clamp 110 is at the proper position, and in this state, the light from the sensor 166 is reflected by the portion without the detected hole 164. The light is detected by the sensor 166. At that time, the hole 164 to be detected is not detected, and it is determined that the closed position of the clamp 110 is at the proper position. On the other hand, when the clamp 110 is not in the proper closed position, that is, when the clamp 110 is not completely closed, the light from the sensor 166 passes through the detection hole 164 and the light is detected by the sensor 166. Not done. If the detected hole 164 is detected at that time, it is determined that the closed position of the clamp 110 is not at the proper position. When it is determined that the closed position of the clamp 110 is not the proper position, the operation of the component feeder 26 and the component mounter 10 are stopped.

Here, as a special case, let us consider a case where the lead Le is bent and the component P is inclined. In this case, it is expected that the two leads Le are guided to one V notch 154, as shown in FIG. In that case, as shown in FIG. 14C as an abnormal clamp, when the clamp 110 is closed, the closed position of the clamp 110 is not the proper position. FIG. 14B shows the state of the normal clamp, but as can be seen by comparison with this, in the state shown in FIG. 14C, the two leads Le overlap and the clamp 110 is not completely closed. .. The component feeder 26 detects a detected hole 164 provided in the holding plate 128 as a detection target, so that a plurality of leads Le are guided by one V notch 154 (hereinafter, referred to as “lead overlapping state”). It is also possible to detect.

However, the proper closed position of the clamp 110 differs depending on the diameter of the lead Le, and it is necessary to consider whether or not the clamp 110 is at the proper closed position. Specifically, in the case of the lead Le having a diameter smaller than that of the lead Le shown in FIGS. 14B and 14C, the results are as shown in FIGS. The proper closing position will be different. In the extreme, when the sandwiching plate 128 shown in FIGS. 14B and 14C is used for the component P of the lead Le shown in FIGS. 14D and 14E, an abnormality occurs. Even in the clamped state, it may be determined that the clamp is in the normal state.

As described above, in the component feeder 26, the sandwiching plate 128 provided with the guide portion 150 is exchanged according to the component P to be handled. Then, the sandwiching plate 128, that is, the guide portion 150 thereof is provided with a detected hole 164 that is a detected portion, and any sandwiching plate 128, that is, any guide portion 150, the detected hole 164. However, it is provided at a position corresponding to the diameter of the lead Le of the corresponding component. Since the sandwiching plate 128 is exchanged, it is possible to save the trouble of adjusting the position of the sensor 166 according to the component P.

In view of the function of the clamp closed position confirmation mechanism 160 described above, the clamp closed position confirmation mechanism 160 has a proper position in the feed direction of each of the leads Le included in the component P sent to the supply position SS. It is supposed to function as a lead position confirmation mechanism for confirming whether or not it is in the position at the supply position SS.

v) Feed confirmation mechanism In order to position the component P, more specifically, the lead Le of the component P at the specified position by the positioning mechanism 108 at the supply position SS, the feed amount of the tape-formed component TP by the feed mechanism 70 is adjusted. It is assumed that it is appropriate, that is, it is accurately fed by the feed pitch p3. In view of this, the component feeder 26 includes a feed confirmation mechanism for confirming whether or not the tape-formed component TP has been fed by the feed mechanism 70 at the feed pitch p3.

As shown in FIG. 8, the feed confirmation mechanism 170 is provided between the feed mechanism 70 and the positioning mechanism 108 in the feed direction. That is, it is provided on the downstream side of the feeding mechanism 70 and on the upstream side of the positioning mechanism 108. More specifically, referring to FIG. 9 and FIG. 10, the feed confirmation mechanism 170 feeds the pin 172 inserted into the feed hole FH formed in the carrier tape CT of the tape forming component TP and the pin 172. The pin insertion mechanism 174 to be inserted into the hole FH and the sensor 176 for detecting whether or not the pin 172 is inserted into the feed hole FH by the pin insertion mechanism 174 are configured.

More specifically, the pin 172 is held by a swing lever 178 as a movable body. The swing lever 178 has a shaft (not shown) inserted into the shaft hole 180, as can be seen from FIGS. 9C and 10C in which the swing lever 178 and the pin 172 are mainly shown. As a result, the feeder main body is swingably held around the central axis of the shaft hole 180. The swing lever 178 is biased to the left by a spring 182 which is a compression coil spring. On the other hand, the roller 184 is provided on the support bar 78 described above, and when the support bar 78 is retracted, the roller 184 is connected to the vertical wall of the swing lever 178 as shown in FIG. The portion 186 abuts from the left. Therefore, the pin 172 is retracted to the position displaced to the right of the guide rail 62, that is, to a position that does not hinder the feeding of the tape-formed component TP.

When the support bar 78 is advanced, that is, when the tape-forming component TP is fed by the feeding mechanism 70, the roller 184 is advanced to a position where it does not engage with the vertical wall portion 186, as shown in FIG. The urging force of the spring 182 causes the swing lever 178 to be displaced leftward. Since the pin 172 is located at the position ahead of the position of the check claw 96 by the feed pitch p3 (equal to the hole pitch p2 of the feed hole FH), the tape-making component TP is fed by the feed mechanism 70 to the feed pitch p3. If it is correctly fed, the pin 172 is displaced leftward and inserted into the feed hole FH. That is, the pin insertion mechanism 174 is configured to include the rollers 184, the swing lever 178, and the like. Incidentally, when the support bar 78 is retracted, the roller 184 engages with the vertical wall portion 186 and returns to the state shown in FIG. 9.

The rocking lever 178 is provided with a detected piece 188. When the pin 172 is displaced to the left, that is, the pin 172 is inserted into the feed hole FH, the detected piece 188 also moves to the left. .. The sensor 176 is adapted to detect the movement of the detected piece 188. The sensor 176 is of a type in which a light source and a detection unit for detecting the light from the light source face each other. When the pin 172 is properly inserted into the feed hole FH, the light from the light source to the detection unit is detected. Since the light is blocked, it is determined that the pin 172 has been inserted into the feed hole FH. Incidentally, when the feed amount is not the feed pitch p3, the pin 172 comes into contact with a portion of the carrier tape CT where the feed hole FH does not exist, thereby prohibiting the pin 172 from moving to the left. .. In that case, since the detected piece 188 does not block the light from the light source to the detection portion, it is determined that the pin 172 is not inserted into the feed hole FH. In that case, the operation of the component feeder 26 and the component mounter 10 are stopped because the feed amount is not appropriate.

As can be seen from the above description, the operation of the feed confirmation mechanism 170, specifically, the operation of the pin insertion mechanism 174 is an operation according to the movement of the support bar 78, and is linked to the feed operation of the feed mechanism 70. Has been done. Even if the tip of the pin 172 is sharp and the feed amount by the feed mechanism 70 is slightly deviated from the feed pitch p3, the pin 172 is inserted into the feed hole FH to cause the deviation. Will be resolved.

As a cause of the feed amount not being the feed pitch p3, for example, the carrier tape CT may be cut as shown in FIG. 5C at the end of the tape-formed component TP. Due to the structure of the feeding mechanism 70 described above, when the cutting is performed at the center of the feeding hole FH as shown in FIG. 5B, the feeding amount is appropriate, but as shown in FIG. This is because the feed amount decreases or increases when the feed hole FH is cut and cut. The feed confirmation mechanism 170 can confirm that the feed amount is not appropriate due to such a cause.

[D] Modified Example Instead of the component feeder 26, the component mounter 10 may employ a component feeder as a modified example described below. As shown in FIG. 15, the component feeder 200 of this modified example is, to put it simply, instead of the feed confirmation mechanism 170 and the clamp closed position confirmation mechanism 160 employed in the component feeder 26, the feed mechanism 70 in the feed direction. A confirmation mechanism 210 having a combined function of these functions is provided on the downstream side of the supply position SS and on the upstream side of the supply position SS. Incidentally, as the positioning mechanism, the positioning mechanism 156 shown in FIG. 13A is adopted.

More specifically, the confirmation mechanism 210 roughly includes a support 212 fixed to the feeder main body, a swing lever 214 swingably held by the support 212, and a pin fixedly held by the swing lever 214. 216, a comb plate 218 exchangeably attached to the swing lever 214, a detected piece 220 fixedly attached to the lower part of the swing lever 214, and a sensor 222 for detecting the detected piece 220. It is configured to include.

Referring to FIG. 16A and FIG. 16B which are also schematically shown from the front side, the swing lever 214 is a compression coil spring interposed between the swing lever 214 and the support 212. The upper end portion is urged to the left (right in the figure) by the spring 224. On the other hand, the swing lever 214 is locked by the main lever 116 (the blade 126 is omitted in the figure) of the clamp 110 described above, and the upper end portion is directed to the left (to the right in the figure). Rotation is limited.

FIG. 16A shows a state in which the clamp 110 is open, and in this state, the swing lever 214 is prohibited from moving the upper end portion to the left side (right side in the figure) of the figure. When the clamp 110 is closed, as shown in FIG. 16B, the operation is allowed, and the operation by the biasing force of the spring 224 is enabled. On the contrary, when the clamp 110 is opened from the closed state, the swing lever 214 is operated by the rotation of the main lever 116 so that the upper end portion moves rightward (leftward in the drawing). By the way, the swing lever 214, which is a movable body, operates so that the upper end of the swing lever 214 moves forward and backward with respect to the lead Le of the component P. The term "advance/retreat motion" may be used as a generic term for.

The comb plate 218 attached to the swing lever 214 is provided with a plurality of notches 226 (specifically, two notches 226) each having a slot shape corresponding to the lead Le of the component P. The comb plate 218 functions as a comb portion of the confirmation mechanism 210. Each notch 226 opens toward the lead Le of the component P similarly to the V notch 154 of the guide plate 158 of the positioning mechanism 156, and is formed to have the same width as the width of the opening end of the V notch 154. There is. When the position of each lead Le of the component P in the feed direction is in an appropriate position, that is, in the position where it can be guided to the specified position by the V notch 154 of the guide plate 158 at the supply position SS, As shown by “OK” on the left side of 16(c), each lead Le passes through each notch 226 as the swing lever 214 advances.

On the other hand, the pin 216 is one of the feed holes FH provided in the carrier tape CT when the tape-making component TP is fed by the feed pitch p3 by the feed mechanism 70 in accordance with the advancing operation of the swing lever 214. It is provided at a position where it can be inserted into.

When the swing lever 214 has properly advanced, the sensor 222 detects the detected piece 220 provided on the swing lever 214. The sensor 222 is of a type in which a light source and a detection unit that detects the light from the light source face each other, and when the swing lever 214 appropriately advances, the detected piece 220 emits light from the light source. Shut off.

When the position of any of the leads Le of the component P is not in the proper position, the tip of the comb plate 218 is attached to one of the leads Le as in the state shown as “NG” on the right side of FIG. 16C. Since the rocking lever 214 is locked, it cannot properly perform the advancing operation. Further, even if the feeding amount of the tape-formed component TP by the feeding mechanism 70 is not appropriate, the pin 216 cannot be inserted into the feeding hole FH provided in the carrier tape CT, and thus the swing lever 214 is also appropriate. Cannot move into. In other words, it is not possible to perform a sufficient advance operation. In that case, the sensor 222 does not detect the detected piece 220, and accordingly, the tape-forming component TP is not fed by the feed mechanism 70 at the feed pitch p3 or is planned to be fed to the feed position SS. It is determined that one of the leads Le of the component P is not in the proper position. When such a determination is made, the operation of the component feeder 200 is stopped.

Based on the function of the confirmation mechanism 210 described above, the confirmation mechanism 210 is provided on the upstream side of the supply position SS in the feeding direction of the tape-formed component TP, and has the component P that is sent to the supply position SS by the feeding mechanism 70. It functions as a lead position confirmation mechanism for confirming whether or not the position of each of the leads Le in the feed direction is at an appropriate position, and whether or not the tape-formed component TP is fed by the feed mechanism 70 at the feed pitch p3. It functions as a feed confirmation mechanism for confirming.

The operation of the confirmation mechanism 210, specifically, the forward/backward movement of the swing lever 214 as a movable body is linked to the opening/closing operation of the clamp 110, and the opening/closing operation is linked to the operation of the feed mechanism 70. Therefore, in the component feeder 200, the operation of the confirmation mechanism 210 is linked to the operation of the feed mechanism 70.

By the way, the guide plate 158 and the comb plate 218 are exchanged according to the supplied component P for the reasons described above. Further, according to the present confirmation mechanism 210, the lead overlapping state described with reference to FIG. 14, that is, the state in which a plurality of leads Le are guided by one V notch 154 cannot be detected in advance. In order to detect the lead overlapping state, for example, the width of the cutout 226 of the comb plate 218 may be made smaller than the width of the open end of the V notch 154 of the guide plate 158 to some extent.

Since the component feeder 26 of the embodiment employs the clamp closing position confirmation mechanism 160 described above, in order to avoid the situation described with reference to FIG. A positioning mechanism configured to integrate the main body portion and the projecting piece portion 142 and replace the sandwiching plate 128 according to the component P is adopted, but in the component feeder 200, the upstream side of the supply position SS. Since the above-mentioned situation is prevented from occurring by the confirmation mechanism 210 provided in the positioning mechanism 156, that is, the main body portion (holding portion) of the holding plate 128 is integrated with the auxiliary lever 118, the projecting piece portion 142 is formed. The positioning mechanism is configured so that only the thin guide plate 158 (guide portion) constituting the above is replaced according to the component P.
