EMBODIMENT

[A] Component Mounting Machine on which Component Feeder is Installed

(18) As illustrated in FIG. 1, a component mounting machine 10 on which a component feeder of the embodiment is installed includes a main body 12, a board conveyance and fixing device 14 which conveys and fixes a board S, a component supply device 16 which supplies a component, such as an electronic component, two mounting heads 18 and 20 for mounting the component on the board S fixed by the board conveyance and fixing device 14 by holding the component supplied from the component supply device 16, and a head moving device 22 which moves the mounting heads 18 and 20 along one plane between the component supply device 16 and the board conveyance and fixing device 14. Incidentally, the head moving device 22 is an XY-robot-type moving device, and moves the mounting heads 18 and 20 in the x-direction and in the y-direction which are illustrated in the drawing.

(19) The component supply device 16 includes a tray-type component supply device 24 which supplies the components aligned in a tray, and a feeder-type component supply device 26 which supplies the component from a taped component. In the drawing, only one feeder-type component supply device 26 is not disposed, but multiple feeder-type component supply devices 26 can be disposed to be aligned. Although will be described in detail later, the feeder-type component supply device 26 illustrated in the drawing is a component feeder of the embodiment, and hereinafter, the feeder-type component supply device 26 will be called a component feeder 26. Incidentally, although will be described in detail later, the component feeder 26 supplies a component having multiple leads, that is, a component with leads.

(20) As illustrated in FIG. 2, the mounting heads 18 and 20 are attached to one slider 28 via a head lifting and lowering devices 30 and 32 which lift and lower each of the mounting heads 18 and 20, and as the slider 28 is moved by the head moving device 22, the mounting heads 18 and 20 are integrally moved along one plane. Meanwhile, the mounting heads 18 and 20 are independently lifted and lowered by the head lifting and lowering devices 30 and 32. In other words, the head lifting and lowering devices 30 and 32 respectively move the mounting heads 18 and 20 in an up-down direction (z-direction illustrated in FIG. 1).

(21) The mounting head 18 mainly loads the component supplied from the tray-type component supply device 24 onto a surface of the board, and includes a suction nozzle 34 which sucks and holds the component by a negative pressure in a lower portion as a component holding device. Meanwhile, the mounting head 20 is mainly for inserting the component supplied from the component feeder 26, that is, each of the multiple leads included in the component, into a hole provided in the board, and a chuck device 36 illustrated in FIG. 3 is provided in the lower portion thereof. Incidentally, FIG. 3(a) is a view illustrating the chuck device 36 from a y-direction illustrated in FIG. 1, and FIG. 3(b) is a view when the chuck device 36 is viewed from x-direction.

(22) The chuck device 36 is configured to include a chuck 38 and a chuck driving device 40, and the chuck 38 is configured to include a fixed claw 42, and an opening and closing claws 44 and 46 provided on both sides of the fixed claw 42. Although the detailed description of the operation is omitted, the chuck driving device 40 oscillates the chuck 38 in a direction illustrated by an outlined arrow in FIG. 3(a). The chuck 38 is configured such that the opening and closing claws 44 and 46 are closed in accordance with the oscillation. A component with leads P (hereinafter, simply, there is a case of being called “component P”) including two leads Le is supplied from the component feeder 26, and as illustrated in FIG. 3(b), the chuck 38 is configured to respectively pinch one of the two leads Le between the opening and closing claw 44 and the fixed claw 42, and another one lead Le between the opening and closing claw 46 and the fixed claw 42, in a state of being closed. In addition, as illustrated in FIG. 4, the component P held by the chuck 38 is mounted on the board S as the leads Le included in the component P is inserted into a hole H provided on the board S.

[B] Taped Component Handled by Component Feeder

(23) In the taped component handled by the component feeder 26, for example, the component P, such as the electronic component, is held at a predetermined disposition pitch p1 on a carrier tape CT as illustrated in FIG. 5(a), and in a taped component TP illustrated in FIG. 5(a), the component with leads P, such as an electrolytic capacitor, and the multiple leads Le (specifically, two leads Le) included in the component P are held on the carrier tape CT. In addition, the component P is a component in which the two leads Le extend in parallel in the same direction, and can be called a component with radial leads. The carrier tape CT is configured of a relatively thick main tape CT1 and an adhesive sticking tape CT2 stuck thereto, and the lead Le is held to be interposed therebetween.

(24) In the carrier tape CT, feed holes FH are punched at a predetermined hole pitch p2. The hole pitch p2 is equal to the disposition pitch p1 of the component P, and each of the feed holes FH is provided in the middle of the component P in a longitudinal direction of the carrier tape CT. The feed holes FH is used in feeding the taped component TP by the component feeder 26. In addition, in the component feeder 26, the taped component TP is fed in a predetermined feeding direction, that is, in the Y-direction illustrated in the drawing.

[C] Component Feeder

(25) i) Outline of Component Feeder

(26) As illustrated in FIG. 6, the component feeder 26 of a schematic embodiment of the component feeder is disposed in the component supply device 16 of the component mounting machine 10 in a state where a box holder 52 which holds a component accommodation box 50 in which the taped component TP is accommodated, a tape guide 54 which guides the taped component TP in the component accommodation box 50 held by the box holder 52 to the component feeder 26, and a waste tape collection box 56 which accommodates the cut carrier tape CT (which will be described later), are attached.

(27) In the upper portion of the component feeder 26, a guide groove 60 which extends in the longitudinal direction is provided, and the taped components TP guided by the tape guide 54 are intermittently fed a predetermined feeding pitch p3 by a predetermined feeding pitch p3 from a tail end side to a front end side in the longitudinal direction of the component feeder 26 through the guide groove 60. In other words, the Y-direction illustrated in the drawing is the feeding direction. Incidentally, in the description above, regarding the direction related to the component feeder 26, a right part is called a front part and a left part is called a rear part in FIG. 6, and the left part and the right part in a case of being seen in the feeding direction of the taped component TP are respectively called the left part and the right part.

(28) In the drawing, the position at which the component P that exits on the most front side is a supply position SS set in the component feeder 26, and the component P is supplied at the position. In other words, the component P positioned at the supply position SS is held by the mounting head 20 including the chuck device 36 described above, and is mounted on the board S. Incidentally, a view in which a part at which the supply position SS exists is illustrated when viewed from obliquely right front upper part, is illustrated in FIG. 7.

(29) ii) Feeding Mechanism

(30) In the description with reference to FIG. 8 in which a state where an exterior cover is removed is illustrated, the taped component TP is held by a guide rail 62 provided in the guide groove 60. In the guide rail 62, a lower portion is folded and bent in a U shape to a left side, and an upper portion is bent to a right side and has a part that serves as a flange. In the drawing, although the taped component TP is not illustrated, the taped component TP is held on the left side of the guide rail 62 in a state where the lower portion is in the U-shaped part. The component feeder 26 includes a feeding mechanism 70 which feeds the taped component TP in this state forward.

(31) The feeding mechanism 70 is configured to include a first slide 72 which is supported to be movable in a front-rear direction in a feeder main body, a double-acting air cylinder 74 which is an actuator that allows the first slide 72 to reciprocate in the front-rear direction, a second slide 76 which is supported by the feeder main body and reciprocates in the front-rear direction in accordance with the operation of the first slide 72, a support bar 78 which is operated integrally with the second slide 76, and a feeding claw 84 and a feeding claw 86 which are supported to be rotatable around the support bar 78 via a bracket 80 and a bracket 82.

(32) In a case of moving the first slide 72 forward by the air cylinder 74, the second slide 76 moves forward in a state of abutting against the first slide 72 by a spring 88 which is a tensile coil spring that passes across between the feeder main body and the second slide 76 (specifically, the support bar 78). When a stopper 90 is established in the feeder main body and moves by a certain distance, the second slide 76 is locked to the stopper 90 and the forward movement thereof is stopped. In this state, only the forward movement of the first slide 72 is allowed. When the first slide 72 returns to the rear part by the air cylinder 74, at a certain position, the first slide 72 abuts against the second slide 76 locked to the stopper 90, and after this, the second slide 76 moves rearward together with the first slide 72.

(33) Base end sections of the feeding claw 84 and the feeding claw 86 are respectively supported to be rotatable by the bracket 80 and the bracket 82 which are fixed to the support bar 78, and are rotatable in a horizontal plane. Distal ends of the feeding claw 84 and the feeding claw 86 are oriented toward the left side. Between each of the brackets 80 and 82 and each of the feeding claws 84 and 86, a spring 92 which is a compression coil spring is installed, and each of the feeding claws 84 and 86 is biased in a direction in which the distal end is oriented toward the left side.

(34) Between the guide rail 62 and the support bar 78, in a posture of extending forward and rearward, a locking plate 94 is installed. In a state illustrated in the drawing, that is, in a state where the support bar 78 is positioned at the rear part, and in other words, in a case where the second slide 76 is positioned at the tail end of a movement range, tail ends of each of the feeding claw 84 and the feeding claw 86 abut against the locking plate 94 by the biasing force of the spring 92.

(35) With reference to FIGS. 9(a) and 10(a) in which a part at which the feeding claw 84 is installed is enlarged and illustrated, in a state where the support bar 78 is positioned at the rear part, as illustrated in FIG. 9(a), a distal end of the feeding claw 84 abuts against the locking plate 94. Meanwhile, when the second slide 76 advances and the support bar 78 advances, the feeding claw 84 also advances, and as illustrated in FIG. 10(a), the distal end of the feeding claw 84 protrudes from the end of the locking plate 94, and the feeding claw 84 is rotated to the position that protrudes from the opening of the guide rail 62 by the biasing force of the spring 92. Although not illustrated, by the advancing of the support bar 78, the feeding claw 86 is also similarly operated, the distal end of the feeding claw 86 protrudes from a long hole provided in the locking plate 94, and the feeding claw 86 is rotated to the position that protrudes from the opening of the guide rail 62 by the biasing force of the spring 92.

(36) An interval between the distal end of the feeding claw 84 and the distal end of the feeding claw 86 is an integral multiple (p2×n) of the hole pitch p2 of the feed hole FH provided in the taped component TP, and when the locked state by the locking plate 94 is released, the distal ends of each of the feeding claw 84 and the feeding claw 86 are inserted into different feed holes FH at the same time. As the supporting plate 78 further advances after the insertion, the taped component TP is fed only by the advancing amount. The further advancing amount is adjusted to an amount which is equal to the hole pitch p2.

(37) As can be ascertained from FIGS. 9(a) and 10(a), and FIGS. 9(b) and 10(b) (the feeding claw 84 is omitted) which are viewed from above, on a side opposite to the feeding claw 84 and the feeding claw 86 of the guide rail 62, that is, on the left side of the taped component TP, a non-return claw 96 is installed to be rotatable. When the front side is called a downstream side in the feeding direction of the taped component TP, and the rear side is called an upstream side, the non-return claw 96 is provided on the downstream side of the feeding claw 84. The non-return claw 96 is biased in the right direction by a force of a spring 98 which is a compression coil spring, and when the taped component TP is fed only by the above-described advancing amount, the non-return claw 96 is inserted into the feed hole FH. Ina case where the non-return claw 96 is inserted into the feed hole FH, the displacement to the upstream side of the taped component TP is prohibited. In addition, in the non-return claw 96, a surface on the upstream side at the distal end is an inclined surface, and the non-return claw 96 is disengaged from the feed hole FH against the biasing force of the spring 98 by the feeding force when feeding the taped component TP to the downstream side even in a state of being inserted into the feed hole FH.

(38) In a state where the non-return claw 96 is inserted into the feed hole FH, by allowing the first slide 72 to retreat, while the taped component TP maintains the position, the feeding claw 84 and the feeding claw 86 also retreat. As can be ascertained from the operation described above, the feeding mechanism 70 is configured to engage the feeding claw 84 and the feeding claw 86 with the feed hole FH, and to feed the taped component TP in the feeding direction by moving the feeding claw 84 and the feeding claw 86, and to feed the taped component TP to the downstream side only by the feeding pitch p3 which is equal to the hole pitch p2 and the above-described disposition pitch p1 by one time of advancing and retreating operation of the air cylinder 74.

(39) iii) Positioning Mechanism and Lead Cutting Mechanism

(40) The component feeder 26 includes a mechanism for positioning the component P at the above-described supply position SS as illustrated in FIGS. 7 and 8, that is, a positioning mechanism 108 for positioning the component P in each of the feeding directions of the two leads Le included in the component P as illustrated in FIG. 11. In addition, in the positioning mechanism 108, a mechanism for cutting a spare part of the two leads Le of the component P positioned at the supply position SS is integrated.

(41) With reference to FIGS. 7, 8, 11, and 12, more specifically, the positioning mechanism 108 generally configures a clamp 110 which includes a first member and a second member which are two members that perform operations relative to each other, and performs an opening and closing action, as a main constituent element. Specifically, the clamp 110 is configured to include a fixing block 112 fixed to the feeder main body, and a lever 114 held to be oscillatable in the feeder main body. Incidentally, the lever 114 functions as one of the first member and the second member, and the fixing block 112 functions as the other one of the first member and the second member.

(42) The lever 114 is configured to include a main lever 116 of which an upper end portion branches into two, and a sub-lever 118 which intersects with the main lever 116, and the main lever 116 and the sub-lever 118 are oscillatable around a common shaft 120. As can be ascertained from FIG. 12(a), in the main lever 116, an upper end portion is biased to a right part by a biasing force of a spring 122 which is a compression coil spring, and in the sub-lever 118, a lower end portion is biased to a right part by the biasing force of a spring 124 which is a compression coil spring.

(43) A blade 126 is attached to the upper end of the main lever 116, and a pinching plate 128 is attached to an upper end of the sub-lever 118. A roller 130 is attached to the lower end portion of the main lever 116, and as illustrated in FIG. 8, the roller 130 functions as a cam follower, and in a case where the first slide 72 advances, the roller 130 is engaged with a cam surface 132 provided in the front end portion of the first slide 72.

(44) The biasing force by the spring 122 is greater than the biasing force by the spring 124, and in a state illustrated in FIG. 12(a), the sub-lever 118 abuts against the rear surface of the blade 126, and a state where the upper ends of each of the main lever 116 and the sub-lever 118 are positioned at the right part, that is, a state where the clamp 110 is open, is achieved. In this state, both of the blade 126 and the pinching plate 128 are disengaged from the fixing block 112.

(45) When the first slide 72 advances, an upper end of the main lever 116 oscillates in a direction toward the left part, and according to this, the sub-lever 118 also oscillates in the same direction. When the main lever 116 and the sub-lever 118 oscillate to a certain degree, as illustrated in FIG. 12(b), in a state where the lead Le of the component P is interposed between a pinching surface 134 provided in the fixing block 112 and a pinching surface 136 provided in the pinching plate 128, oscillation of the sub-lever 118 is stopped. A part at which the pinching surface 134 of the fixing block 112 is provided and a part at which the pinching surface 136 of the pinching plate 128 is provided, respectively function as pinching sections, and the lead Le of the component P is pinched by the pinching sections. In this state, the lead Le is pinched by a force caused by a biasing force of the spring 124.

(46) Furthermore, when the main lever 116 oscillates, as illustrated in FIG. 12(c), the lead Le is cut by the distal end of the blade 126 and the lower end of the pinching surface 134 of the fixing block 112. The distal end of the blade 126 and the lower end of the pinching surface 134 of the fixing block 112 function as one pair of blades which are respectively provided in the above-described first member and the second member, and by the one pair of blades, the lead Le is cut on the distal end side (lower end side) of the part pinched by the above-described pinching section. In other words, the component feeder 26 includes a lead cutting mechanism 138 which cuts the lead Le by the opening and closing action of the clamp configured to include one pair of blades, at the supply position SS.

(47) The component of which the lead Le is cut at the supply position SS is held by the chuck device 36 of the mounting head 20 described above in a state where the lead Le is held by the clamp 110, and is supplied to be mounted on the board S moved by the mounting head 20 after the clamp 110 is open. The opening operation of the clamp 110 is performed by using the biasing force of the spring 122 and the spring 124 as the first slide 72 retreats. Since the operation between an open position illustrated in FIG. 12(a) and a closed position illustrated in FIG. 12(b), that is, the opening and closing action of the clamp 110, is performed in accordance with the advancing and retreating operation of the first slide 72, the operation is interlocked with the operation of the feeding mechanism 70 described above.

(48) In addition, as illustrated in FIG. 11, on the end face on the front side of the fixing block 112 and on the end face on the front side of the main lever 116, a blade 140 and a blade 142 for cutting the carrier tape CT are respectively provided, and by the opening and closing action of the clamp 110, a part of the carrier tape CT which remains after the component P is supplied has already been cut. Apart of the cut carrier tape CT is collected by the waste tape collection box 56 through a collection road 144 (refer to FIG. 6).

(49) In the positioning mechanism 108, it is important that each of the two leads Le included in the component P is positioned at an appropriate position in the feeding direction of the taped component TP. Therefore, at the upper end of the lever 114 which is one of the first member and the second member, specifically, in the pinching plate 128 attached to the upper end of the sub-lever 118, a guide section 150 is provided.

(50) The pinching plate 128 includes a thin piece-like protrusion piece section 152 which protrudes from the pinching surface 136. In the protrusion piece section 152, corresponding to the two leads Le, two V notches 154 and 154 which are respectively open toward the fixing block 112 which is the other one of the first member and the second member in a case where the clamp 110 is at a closed position, are formed. When the clamp 110 is closed, the protrusion piece section 152 moves to cover the fixing block 112, and by the V notches 154 and 154, the two leads Le are guided to a defined position, that is, the position that is a bottom of the V notches 154 and 154. In this manner, the guide section 150 is configured to include the multiple V notches 154 that correspond to the number of leads Le of the component P.

(51) According to the type of the component P, the number of the leads Le, the diameter of the lead Le, the position of the lead Le, the interval between the leads Le, or the like is various, and according to the component P to be supplied, it is necessary to change the number, the shape, the interval or the like of the V notches 154. For example, it is also considered that a positioning mechanism 156 illustrated in FIG. 13(a), that is, a positioning mechanism configured to integrate the main body section (pinching section) of the above-described pinching plate 128 with the sub-lever 118, and to exchange only a thin guide plate 158 (guide section) that configures the protrusion piece section 152 depending on the component P, is employed. FIG. 13(a) illustrates a state where the lead Le of the component P is normally pinched, but in such a configuration, there is a possibility that a defect illustrated in FIGS. 13(b) and 13(c) which is schematically illustrated when viewed from side face, is generated. Specifically, because of a case where the feeding amount of the taped component TP by the feeding mechanism 70 is not appropriate, or a case where any of the leads Le is bent, it is predicted that any of the leads Le is not positioned at an appropriate position, that is, that any of the leads Le is not in the opening of the corresponding V notch 154. In this case, when closing the clamp 110, the lead Le abuts against the part at which the V notch 154 of the guide plate 158 is not formed, the distal end portion of the guide plate 158 itself is deformed to be lifted up while folding and bending the lead Le, and there is a possibility that the clamp 110 reaches the appropriate closed position. Incidentally, in a case where the diameter of the lead Le is narrow, the possibility is particularly increases.

(52) In order to avoid the above-described situation, in the component feeder 26, the pinching plate 128 is made in a state where the main body section thereof and the protrusion piece section 152 are integrated with each other, and specifically, the main body section and the protrusion piece section 152 are formed by one member, and are exchanged depending on the component P for each pinching plate 128. In order to employ such a configuration, that is, in order to employ a configuration in which rigidity of the protrusion piece section 152 is relatively high, in the component feeder 26, in a case where the situation in which the lead Le is not positioned at an appropriate position, the clamp 110 is not closed to the extent that the closed position of the clamp 110 becomes the appropriate position. Therefore, by checking whether or not the closed position of the clamp 110 is an appropriate position, it is possible to easily check whether or not the position of the lead Le is an appropriate position.

(53) iv) Clamp Closed Position Checking Mechanism

(54) From the above-described point of view, in the component feeder 26, a clamp closed position checking mechanism 160 for checking whether or not the closed position of the clamp 110, that is, the operation position in a state where the clamp 110 is closed is an appropriate position when pinching the lead Le of the component P by the clamp 110 at the supply position SS, is provided.

(55) Specifically, as illustrated in FIG. 11, in the pinching plate 128, an overhang section 162 which overhangs from the sub-lever 118 forward is provided, a detection target hole 164 is formed to penetrate the overhang section 162, the detection target hole 164 is detected by a light reflection-type sensor 166 installed therebelow, and according to whether or not the detection target hole 164 is detected by the sensor 166, it is possible to check whether or not the closed position of the clamp 110 is an appropriate position. In other words, in the component feeder 26, the clamp closed position checking mechanism 160 is configured including the detection target hole 164 that serves as the detection target section provided in the guide section which is a part of the pinching plate 128, and the sensor 166 which considers the detection target hole 164 as a target of detection.

(56) Specifically, a state where the clamp 110 is sufficiently closed is a state where the closed position of the clamp 110 is an appropriate position, and in this state, the light from the sensor 166 is reflected by a part at which the detection target hole 164 does not exist, and the light is detected by the sensor 166. At this time, the detection target hole 164 is not detected, and it is determined that the closed position of the clamp 110 is an appropriate position. Meanwhile, in a state where the closed position of the clamp 110 is not an appropriate position, that is, in a case where the clamp 110 is closed, the light from the sensor 166 penetrates the detection target hole 164, and the light is not detected by the sensor 166. At this time, the detection target hole 164 is detected, and it is determined that the closed position of the clamp 110 is not an appropriate position. In addition, in a case where it is determined that the closed position of the clamp 110 is not an appropriate position, the operation of the component feeder 26 and the operation of the component mounting machine 10 are stopped.

(57) Here, as a certain special case, for example, a case where the lead Le is bent and the component P is inclined is considered. In this case, as illustrated in FIG. 14(a), it is predicted that the two leads Le are guided to one V notch 154. In this case, as an abnormal clamp, as illustrated in FIG. 14(c), the closed position of the clamp 110 is not an appropriate position in a case where the clamp 110 is closed. FIG. 14(b) illustrates a state of the normal clamp, and as can be ascertained from the comparison, in a state illustrated in FIG. 14(c), since the two leads Le overlap each other, the clamp 110 is not closed. The component feeder 26 can also detect the state (hereinafter, there is a case of being called “lead overlapping state”) where the multiple leads Le are guided to one V notch 154, regarding the detection target hole 164 provided in the pinching plate 128 as a detection target.

(58) However, it is necessary to consider that the appropriate closed position of the clamp 110 varies in accordance with the diameter of the lead Le, when checking whether or not the closed position of the clamp 110 is an appropriate position. Specifically, in a case of the lead Le having a narrower diameter than that of the lead Le illustrated in FIGS. 14(b) and 14(c), the state of FIGS. 14(d) and 14(e) is achieved, and an appropriate closed position of the clamp 110 varies. Extremely, with respect to the component P of the lead Le illustrated in FIGS. 14(d) and 14(e), in a case of using the pinching plate 128 illustrated in FIGS. 14(b) and 14(c), there is a concern that it is determined that the state of the normal clamp is achieve even in a state of the abnormal clamp.

(59) As described above, in the component feeder 26, depending on the component P to be handled, the pinching plate 128 provided in the guide section 150 is exchanged. In addition, in the pinching plate 128, that is, in the guide section 150, the detection target hole 164 which is a detection target section is provided, and in any of the pinching plates 128, that is, in any of the guide sections 150, the detection target hole 164 is provided at a position that corresponds to the diameter of the lead Le of the component corresponding thereto. As the pinching plate 128 is exchanged, it is possible to save time and labor for adjusting the position of the sensor 166 depending on the component P.

(60) In addition, considering the functions of the clamp closed position checking mechanism 160 described above, the clamp closed position checking mechanism 160 functions as a lead position checking mechanism for checking whether or not the position in the feeding direction of each of the multiple leads Le included in the component P fed to the supply position SS is an appropriate position, at the supply position SS.

(61) v) Feeding Checking Mechanism

(62) At the supply position SS, in order to position the component P, particularly, the lead Le of the component P at a defined position by the positioning mechanism 108 it is assumed that the feeding amount of the taped component TP by the feeding mechanism 70 is appropriate, that is, that the taped component TP is accurately fed only by the feeding pitch p3. Considering this, the component feeder 26 includes the feeding checking mechanism for checking whether or not the taped component TP is fed by the feeding pitch p3 by the feeding mechanism 70.

(63) As illustrated in FIG. 8, a feeding checking mechanism 170 is provided between the feeding mechanism 70 and the positioning mechanism 108 in the feeding direction. In other words, the feeding checking mechanism 170 is provided on the downstream side of the feeding mechanism 70, and is provided on the upstream side of the positioning mechanism 108. In specific description with reference to FIGS. 9 and 10, the feeding checking mechanism 170 is configured to include a pin 172 which is inserted into the feed hole FH punched on the carrier tape CT of the taped component TP, a pin insertion mechanism 174 which inserts the pin 172 into the feed hole FH, and a sensor 176 for detecting whether or not the pin 172 is inserted into the feed hole FH by the pin insertion mechanism 174.

(64) Specifically, the pin 172 is held by a rocking lever 178 that serves as a movable body. As can be ascertained from FIGS. 9(c) and 10(c) which focus on the rocking lever 178 and the pin 172, the rocking lever 178 is held to be oscillatable around a center axis of a shaft hole 180 in the feeder main body as the shaft (not illustrated) is inserted into the shaft hole 180. The rocking lever 178 is biased to the left part by a spring 182 which is a compression coil spring. Meanwhile, in a state where a roller 184 is installed in the support bar 78 described above, and the support bar 78 retreats, as illustrated in FIG. 9, the roller 184 abuts against a vertical wall section 186 of the rocking lever 178 from the left part. Therefore, the pin 172 retreats to a state of being displaced to the right part of the guide rail 62, that is, to a position at which the feeding of the taped component TP is not interrupted.

(65) When the support bar 78 advances, that is, when the taped component TP is fed by the feeding mechanism 70, as illustrated in FIG. 10, the roller 184 advances to the position at which the roller 184 is not engaged with the vertical wall section 186, and the rocking lever 178 is displaced to the left part by the biasing force of the spring 182. Since the pin 172 is positioned further at a front position only at the feeding pitch p3 (which is equal to the hole pitch p2 of the feed hole FH) than the position of the non-return claw 96, in a case where the taped component TP is correctly fed only at the feeding pitch p3 by the feeding mechanism 70, the pin 172 is displaced to the left part and is inserted into the feed hole FH. In other words, the pin insertion mechanism 174 including the roller 184 and the rocking lever 178 is configured. Incidentally, as the support bar 78 retreats, the roller 184 is engaged with the vertical wall section 186, and returns to a state illustrated in FIG. 9.

(66) In the rocking lever 178, a detection target piece 188 is provided, and by the displacement of the pin 172 to the left part, that is, the insertion of the pin 172 into the feed hole FH, the detection target piece 188 also moves to the left part. The sensor 176 detects the movement of the detection target piece 188. The sensor 176 is a type in which the light source and the detection section which detects the light from the light source face each other, and in a case where the pin 172 is appropriately inserted into the feed hole FH, the light from the light source to the detection section is blocked, and it is determined that the pin 172 is inserted into the feed hole FH by the blocking of the light. Incidentally, in a case where the feeding amount is the feeding pitch p3, the pin 172 abuts against a location at which the feed hole FH does not exist in the carrier tape CT, and accordingly, the movement of the pin 172 to the left part is prohibited. In this case, since the detection target piece 188 blocks the light from the light source to the detection section, it is determined that the pin 172 is not inserted into the feed hole FH. In addition, in this case, the feeding amount is not appropriate, and the operation of the component feeder 26 and the operation of the component mounting machine 10 are stopped.

(67) As can be ascertained above, the operation of the feeding checking mechanism 170, specifically, the operation of the pin insertion mechanism 174, is an operation which corresponds to the movement of the support bar 78, and is interlocked with the feeding operation of the feeding mechanism 70. In addition, the distal end of the pin 172 is sharp, and in a case where the feeding amount by the feeding mechanism 70 is slightly shifted from the feeding pitch p3, the shifted state is released by the insertion of the pin 172 into the feed hole FH.

(68) In addition, as a reason why the feeding amount is not the feeding pitch p3, for example, a case where the carrier tape CT is cut as illustrated in FIG. 5(c) at the tail end of the taped component TP, is considered. This is because, in the structure of the above-described feeding mechanism 70, as illustrated in FIG. 5(b), in a case where the carrier tape CT is cut at the center of the feed hole FH, the feeding amount is appropriate, but as illustrated in FIG. 5(c), in a case where the feed hole FH is shifted and cut, the feeding amount becomes small or large. The feeding checking mechanism 170 can check that the feeding amount is not appropriate due to such a reason.

[D] Alternative Embodiment

(69) Instead of the above-described component feeder 26, in the component mounting machine 10, it is possible to employ a component feeder which is an alternative embodiment which will be described hereinafter. As illustrated in FIG. 15, briefly speaking, instead of the feeding checking mechanism 170 and the clamp closed position checking mechanism 160 which are employed in the component feeder 26, a component feeder 200 of the alternative embodiment includes a checking mechanism 210 having a function into which the functions are integrated, on the upstream side of the supply position SS which is the downstream side of the feeding mechanism 70 in the feeding direction. Incidentally, as the positioning mechanism, a positioning mechanism 156 illustrated in FIG. 13(a) is employed.

(70) Specifically, the checking mechanism 210 is generally configured to include a support 212 fixed to a feeder main body, a rocking lever 214 which is held to be oscillatable by the support 212, a pin 216 which is held to be fixed to the rocking lever 214, a comb plate 218 which is attached to the rocking lever 214 to be exchangeable, a detection target piece 220 attached to be fixed to a lower portion of the rocking lever 214, and a sensor 222 which detects the detection target piece 220.

(71) In the description with reference to FIGS. 16(a) and 16(b) which are schematically illustrated when viewed from the front side, the upper end portion of the rocking lever 214 is biased to the left part (right part in the drawing) by a spring 224 which is a compression coil spring interposed between the rocking lever 214 and the support 212. Meanwhile, the rocking lever 214 is locked by the main lever 116 (in the drawing, the blade 126 is omitted) of the above-described clamp 110, and the rotation of the upper end portion of the rocking lever 214 to the left part (right part of the drawing) is restricted.

(72) FIG. 16(a) illustrates a state where the clamp 110 is open, and in this state, the operation of the upper end portion of the rocking lever 214 to the left part (right part of the drawing) of the drawing is prohibited. In a case where the clamp 110 is closed, as illustrated in FIG. 16(b), the operation is allowed, and the operation by a biasing force of the spring 224 is possible. On the contrary, in a case where the clamp 110 is open from the closed state, the upper end portion of the rocking lever 214 is operated by the rotation of the main lever 116 so as to move to the right part (left part of the drawing). Incidentally, since the rocking lever 214 which is a movable body is operated such that the upper end portion thereof advances and retreats with respect to the lead Le of the component P, hereinafter, regarding the operation of the rocking lever 214, there is a case where an expression of an advancing operation, a retreating operation, and an advancing and retreating operation generally indicating both of them.

(73) In the comb plate 218 attached to the rocking lever 214, corresponding to the lead Le of the component P, multiple cutouts 226 (specifically, two cutouts 226) made in a shape of a slot are provided, and the comb plate 218 functions as a comb section of the checking mechanism 210. Each of the cutouts 226 is open toward the lead Le of the component P similar to the V notch 154 of the guide plate 158 of the positioning mechanism 156, and is formed as a part having a width which is the same as the width of the opening end of the V notch 154. In a case where the position in the feeding direction of each of the leads Le of the component P is an appropriate position, that is, in a case where the position is a position at which guiding to the defined position by the V notch 154 of the guide plate 158 is possible at the supply position SS, as illustrated in a state illustrated as “OK” on the left side of FIG. 16(c), each of the leads Le passes through each of the cutouts 226 in accordance with the advancing and retreating operation of the rocking lever 214.

(74) Meanwhile, in a case where the taped component TP is fed only at the feeding pitch p3 by the feeding mechanism 70, a pin 216 is provided at a position at which the pin 216 can be inserted into one feed hole FH provided on the carrier tape CT in accordance with the advancing operation of the rocking lever 214.

(75) In a case where the rocking lever 214 appropriately performs the advancing operation, the sensor 222 detects the detection target piece 220 provided in the rocking lever 214. The sensor 222 is a type in which the light source and the detection section which detects the light from the light source face each other, and in a case where the rocking lever 214 appropriately performs the advancing operation, the detection target piece 220 blocks the light from the light source.

(76) In a case where the position of any lead Le of the component P is not an appropriate position, as illustrated in a state illustrated as “NG” on the right side of FIG. 16(c), since the distal end of the comb plate 218 is locked to any of the leads Le, the rocking lever 214 cannot appropriately perform the advancing operation. In addition, even in a case where the feeding amount of the taped component TP by the feeding mechanism 70 is not appropriate, since the pin 216 cannot be inserted into the feed hole FH provided on the carrier tape CT, the rocking lever 214, therefore, the rocking lever 214 cannot appropriately perform the advancing operation. In other words, the advancing operation cannot be sufficiently performed. In this case, the sensor 222 does not detect the detection target piece 220, and according to this, it is determined that the taped component TP is not fed at the feeding pitch p3 by the feeding mechanism 70, or that any of the leads Le of the planned component P supplied to the supply position SS is not at an appropriate position. In a case where such determination is not performed, the operation of the component feeder 200 is stopped.

(77) Based on the function of the above-described checking mechanism 210, the checking mechanism 210 is provided on the upstream side of the supply position SS in the feeding direction of the taped component TP, functions as a lead position checking mechanism for checking whether or not the position in the feeding direction of each of the multiple leads Le included in the component P fed to the supply position SS by the feeding mechanism 70 is an appropriate position, and functions as the feeding checking mechanism for checking whether or not the taped component TP is fed at the feeding pitch p3 by the feeding mechanism 70.

(78) An operation of the checking mechanism 210, specifically, the advancing and retreating operation of the rocking lever 214 that serves as the movable body, is interlocked with the opening and closing action of the clamp 110, and the opening and closing operation is interlocked with the operation of the feeding mechanism 70. Therefore, in the component feeder 200, the operation of the checking mechanism 210 is interlocked with the operation of the feeding mechanism 70.

(79) Incidentally, the guide plate 158 and the comb plate 218 are exchanged depending on the component P to be supplied due to the reason described above. In addition, according to the checking mechanism 210, the lead overlapping state described with reference to FIG. 14, that is, the state where the multiple leads Le are guided to one V notch 154, cannot be detected in advance. In order to detect the lead overlapping state in advance, for example, means for reducing the width of the cutout 226 of the comb plate 218 to be approximately smaller than the width of the opening end of the V notch 154 of the guide plate 158, may be considered.

(80) In addition, in the component feeder 26 of the embodiment, in order to employ the above-described clamp closed position checking mechanism 160, the positioning mechanism 108 which is supposed to avoid the situation described with reference to FIG. 13, that is, the positioning mechanism which is configured to exchange the pinching plate 128 depending on the component P for each of the pinching plates 128 by integrating the main body section thereof with the protrusion piece section 142, is employed, but in the component feeder 200, since generation of the above-described situation is prevented in advanced by the checking mechanism 210 provided on the upstream side of the supply position SS, the positioning mechanism 156, that is, the positioning mechanism which is configured to exchange only the thin guide plate 158 (guide section) that configures the protrusion piece section 152 by integrating the main body section (pinching section) of the pinching plate 128 with the sub-lever 118 depending on the component P, is employed.
